ITEM 1.  DESCRIPTION OF BUSINESS

         Universal Seismic Associates, Inc. (hereinafter referred to together
with its subsidiaries as "the Company") was incorporated in Delaware in July
1988.  Prior to May 1994, the Company was exclusively a seismic data
acquisition company providing services through its subsidiary, Universal
Seismic Acquisition, Inc. ("Acquisition").  In May 1994, the Company acquired a
data processing services company and renamed it Universal Seismic Technologies,
Inc. ("UST").  In January 1996 the Company formed a new wholly owned
subsidiary, UNEXCO, Inc. ("UNEXCO") to conduct oil and gas exploration and
production activities.

         The Company is a provider of three-dimensional ("3-D") seismic
acquisition and processing services to the energy industry in the United States
("U.S.") and also participates in carefully selected oil and gas projects
through UNEXCO.  Oil and gas companies utilize seismic data in determining
suitable locations for drilling wells, in the development of oil and gas
reserves and, increasingly, in reservoir management.  The Company acquires, on
a contract basis, seismic data for energy and energy service companies, which
typically have exclusive ownership of the data.  The Company also processes
seismic data for both acquisition clients and energy customers that have
acquired data from other sources.

         In September 1991, the Company obtained its first data acquisition
system with 3-D capability.  The system, an Input/Output, Inc. ("I/O") SYSTEM
TWO ("SYSTEM TWO") employs a 24 bit analog-to-digital converter using advanced
delta sigma technology.  The Company presently has the equipment capability of
operating up to five such I/O systems.

         The Company uses state-of-the-art seismic recording systems and
experienced crews, both of which are necessary in order to provide 3-D seismic
services to the oil and gas community.  The Company has further enhanced its
traditional acquisition business by offering 3-D processing and analysis along
with global position system ("GPS") surveys.  The Company began operating in
swamp and shallow water environments in conjunction with the addition of its
I/O SYSTEM TWO Remote Seismic Recorder crews in October 1995 and June 1996.

DATA ACQUISITION

         Seismic Crews.  A seismic crew typically consists of a supervisor,
crew chief, assistant crew chief, an observer who operates the seismograph and
controls the recording of seismic data, and general laborers who place and move
the geophones and related equipment.  A seismic crew typically uses general
laborers who are part of either (i) a drill crew that drills holes for
explosives and shooters who detonate the explosives or (ii) a vibroseis crew
that operates the vibroseis trucks. A fully staffed seismic crew typically
consists of 35 to 55 people.  The Company has the ability to staff its
acquisition crews according to specific client requirements.  The Company
operated three crews during most of the quarter ended September 30, 1997, and
if all of its equipment were placed in operation the Company would have to hire
and train additional personnel.  The market for experienced personnel is
presently very tight.

         Contracts.  The Company's Data Acquisition activities are conducted
under contracts with customers who typically retain exclusive ownership of the
acquired seismic data.  Contracts, which are awarded on a competitive bid
basis, are either "turnkey" contracts which provide for a fixed fee to be paid
to the Company for each unit of data acquired or "term" contracts which provide
for a fixed monthly fee and bonuses for production during the term of a
project.  Turnkey contracts generally can provide more profit potential for the
Company, but involve more risk because of potential down time for weather and
other types of delays.

DATA PROCESSING

         The Company's Data Processing center located in Houston, Texas is a
high technology provider of seismic data processing and analysis.  Data
Processing combines raw data collected in the field and enhances it through
various processes into a form ready for interpretation by customers in the oil
and gas industry.  The Company has added externally developed software and
hardware operating on a Unix based platform to enhance its 3-D processing
capabilities.  The center utilizes its internally developed, PC-based,
interactive workstations for smaller 3-D projects and two-dimensional ("2-D")
processing.

         The Company also reprocesses older existing data using current
techniques in order to enhance the usefulness of that data.

OIL AND GAS

         The Company participates in oil and gas exploration projects through
its wholly owned subsidiary, UNEXCO.  The Company earns or purchases carried
and working interests in carefully selected 3-D seismic projects with the goal
of creating substantial oil and gas reserves and a revenue stream from these
interests.

          The Company typically earns a working interest in a prospect by
acquiring the 3-D seismic data using its own acquisition and processing
resources.  Partners in the prospect typically contribute the oil and gas
leases and/or options, geological and engineering expertise and operating
capability.  UNEXCO maintains a state-of-the-art interpretation workstation,
and together with the Company's partners, jointly interprets the 3-D seismic
data.  After interpreting the 3-D data and integrating the geological and
engineering data, the Company and its partners will decide whether to drill the
prospect themselves or try to sell their interests for cash or a carried
interest to oil and gas industry participants.

         As of September 30, 1997, the Company had participated in ten
completed 3-D seismic programs (nine in fiscal year 1997) totaling
approximately two hundred twenty square miles of 3-D program.  The Company
earned an interest in one additional project by reprocessing an existing 3-D
data set and is currently permitting an additional program.  For additional
information on oil and gas activities, see "Oil and Gas" under Item 2.

SEASONALITY

         The Company has the opportunity to generate its highest Data
Acquisition revenues during the summer months, primarily because this period
typically provides for more recording hours due to longer days.  Although
certain seasons during the year generally provide better working conditions,
adverse weather conditions may impact Data Acquisition revenue at any time
throughout the year.

CUSTOMERS

         The Company's Data Acquisition customers include major and independent
oil and gas exploration companies and service companies.  The following table
sets forth the Company's Data Acquisition





                                       4

customers who accounted for 10% or more of the Company's revenues in either of
the past two fiscal years:

</TABLE>

         -------
         *Less than 1%

         The Company's mix of customers changes yearly as contracts are awarded
and completed.  The Company is unable to anticipate whether significant
portions of its future revenues may be attributable to a few customers,
although it is likely the customer mix will change from year to year.

COMPETITION

         The acquisition and processing of seismic data for the oil and gas
exploration industry is highly competitive.  Although reliable comparative
figures are not available, the Company believes, and it should be assumed, that
some of its principal competitors have more extensive and diversified
operations and some also have financial, operating and other resources
substantially in excess of those available to the Company.

         The Company's competitors for seismic Data Acquisition and Data
Processing contracts include Western Atlas, Veritas DGC, Inc., the GECO
division of Schlumberger, Inc., Grant Geophysical, Boone Geophysical, Inc.,
Tidelands Geophysical Co., Inc. and several other companies.  Competitive
factors that affect the decision on who is awarded a 3-D Data Acquisition
contract include past performance, dependability, reputation, price and
availability of equipment.  For Data Processing, industry reputation,
turnaround time, and price are the critical factors in receiving a job.

         The Company operates in the highly competitive areas of oil and gas
exploration, development and production.  The Company's competitors include
major integrated oil and gas companies and substantial independent energy
companies, many of which possess greater financial and other resources than the
Company.

BACKLOG

         On June 30, 1997, the Company had a backlog of Data Acquisition
contracts of approximately $15.0 million.  In most cases, the agreements may be
terminated by the customer upon 30 days written notice without substantial
penalty.  For this and other reasons, the Company's backlog at any particular
date may not be indicative of the Company's revenues or other operating results
for any succeeding fiscal period.  The Company can not, therefore, assure that
the backlog will be realized as revenue.  At June 30, 1997 the Company's Data
Processing center had contracted backlog of approximately $182,000.  These
contracts are generally terminable by the customer at any time prior to the
actual work being done and, therefore, may not be indicative of future revenues
or operating results.

         On September 30, 1997, the Company had a Data Acquisition backlog of
$4.8 million and a Data Processing Backlog of $116,000.

SUPPLIERS

         The Company's primary supplier of seismic data acquisition equipment
is I/O.  This equipment and related replacement parts are readily available
from I/O and other industry suppliers and can be obtained under leasing or
purchasing arrangements.  Management believes that its relationship with I/O and
other various equipment suppliers is satisfactory.

EMPLOYEES

         On June 30, 1997, the Company employed 244 people, all of whom are
full time employees, and none of whom is covered by a collective bargaining
agreement. The Company considers its employee relations to be satisfactory.

SIGNIFICANT DEVELOPMENTS SINCE JUNE 30, 1996

         Business Expansion.  In fiscal 1997 the Company continued the
expansion of its operations.  Data Acquisition activity increased due to a full
year of operation from the two most recently added 3-D acquisition crews.  The
Company began operating in swamp and shallow water environments in conjunction
with the addition of these crews in October 1995 and June 1996.  This
represented the Company's first significant Data Acquisition effort in these
environments.  The Company's data acquisition crews experienced reduced gross
margins that when combined with indirect overhead, depreciation and interest
expenses lead to fiscal 1997 operational losses.  The reduced gross margins
also resulted from less than full utilization of the Company's crews and
operational difficulties incurred on several significant projects.  The
Company's oil and gas exploration and production operation recognized its first
revenues in the current fiscal year and reported proved reserves with an SEC
PV10 value of $8,002,300.

         Aborted Merger, Proxy Fight, and Shareholder Suit.  During fiscal 1997
the Company was involved in an aborted merger that led to a proxy fight with a
group of shareholders.  This same group of shareholders filed a suit against
the Company and its directors in United States District Court in Delaware.  The
proxy fight was resolved at the annual shareholders meeting held in February
1997 at which management's slate of directors was reelected and all proposals
in opposition to management were defeated.  The shareholder suit was settled
and received final court approval on October 1, 1997.  For additional
information, see Item 3 "Legal Proceedings".  The Company incurred significant
costs related to the aborted merger, proxy fight and shareholder suit.  These
costs significantly impacted fiscal 1997 operating losses.

         The Company restated its financial statements for the three month
periods ended September 30, 1996 and December 31, 1996.  This action was taken
as a result of an internal review by the Audit Committee of the Company's Board
of Directors, which had been commenced in February 1997 in response to
allegations made by a stockholder who pursued litigation against the Company.
The review identified that certain seismic acquisition start-up costs had been
deferred to be amortized over subsequent periods.  Some companies within the
seismic industry utilize an accounting policy which defers and amortizes such
crew start-up costs.  The Company, after consulting with its independent
accountants, determined that the historical policy of expensing start-up costs
should be utilized for accounting for such costs.  Additionally, it was
determined that the Company mistakenly recognized revenue related to a project
involving UNEXCO, when such revenues should have offset capitalized costs.
Accordingly, the previously reported financial results for the three month
periods ended September 30, 1996 and December 31, 1996 were restated. Previously
reported results of operations were overstated by $865,447 for the three months
ended September 30, 1996 and understated by $162,537 for the three months ended
December 31, 1996.





                                       6
<PAGE>   7



         Financing Activities and Debt Covenants.  On December 20, 1996 the
Company entered into a financing agreement with RIMCO Partners, L.P., RIMCO
Partners II, L.P., RIMCO Partners III, L.P. and RIMCO Partners IV, L.P.
(collectively, the "RIMCO Partnerships") to provide $4,000,000 (increased to
$5,500,000 on March 27, 1997) under a revolving credit facility for the
expansion of the Company's exploration and production activities.  On March 27,
1997 the Company borrowed an additional $2,000,000 from the RIMCO Partnerships
for general working capital purposes.  In August 1997 the Company borrowed an
additional $2,000,000 from the RIMCO Partnerships with proceeds being utilized
to fund the shareholder litigation settlement and legal and accounting fees
incurred as a result of such litigation.  The liability for borrowing from the
RIMCO Partnerships was $18,182,516 as of September 30, 1997.

         The RIMCO Partnerships have waived the covenants under the various
financing agreements until July 1, 1998.  They have also agreed to defer
payments of interest and principal due after June 30, 1997 until December 1,
1997.  Also, the Company is presently not in compliance with several covenants
related to its revolving line of credit agreement on accounts receivable from
another financial institution.  The Company was unable to obtain a waiver, but
still receives advances under the agreement.

         Unusual Charge.  The Company leases a 720 channel OPSEIS 5586
telemetry acquisition system under an operating lease through March 2000.  Due
to the recording limitations of this system, the Company believes it has become
non-competitive in the 3-D data acquisition market.  The system has not
operated since October 1996 and the Company recognized the remaining $929,121
lease payments in the fourth quarter of fiscal 1997.

         Additional Recent Developments.  In August 1997 the Company's Board of
Directors engaged Morgan Keegan & Company, Inc. ("Morgan Keegan") to assist in
exploring, developing and recommending various strategic alternatives designed
to enhance shareholder value.  These alternatives may include the possible
merger or business combination of the Company with another entity as well as
capital raising or recapitalization or reorganization strategies.

ITEM 2.  DESCRIPTION OF PROPERTY

         The Company leases corporate office facilities in Houston, Texas,
consisting of approximately 19,779 square feet, under a 120 month lease
expiring on June 14, 2005, subject to the Company's option to cancel on, but
not before or after, the 60th month, or the 84th month, with monthly rental of
$18,011.  The Company, from time to time, also leases temporary offices for its
field crews, the terms of such leases being dependent on the size and term of
the project.  All real property leased by the Company is in good condition.

DATA ACQUISITION

         The Company has the equipment capability of operating up to five 3-D
Data Acquisition crews utilizing I/O SYSTEM TWO equipment.  The Company's
approximately 8,100 channels of I/O data recording equipment are
interchangeable among its crews, allowing for the combination of crews when
necessary.  This provides the Company with flexibility in designing recording
programs to meet the specific requirements of each project.  Up to three I/O
Systems can be operated using cable technology to link remote signal
conditioners to the central electronics unit or control center.  Up to two I/O
RSR crews can be operated using radio telemetry technology to link the system.
This telemetry technology allows the Company to operate in environmentally
sensitive areas such as swamp/marsh areas along the Gulf Coast





                                       7
<PAGE>   8



and in other challenging geographic areas.  The crews typically operate along
the Gulf Coast, from Texas to Florida, and have the ability to use dynamite,
airgun and vibroseis energy sources.

         In addition, the Company has a 720 channel OPSEIS 5586 telemetry
acquisition system under an operating lease.  This system was in operation for
approximately four months during the fiscal year ended June 30, 1997.  Due to
the recording limitations of this system, the Company believes it has become
non-competitive in the 3-D data acquisition market.  The Company, therefore,
expensed the remaining portion of the related operating lease in fiscal 1997
and does not anticipate significant operation of this system in the future.

DATA PROCESSING

         The Company operates a Silicon Graphics Power Challenge system as its
primary hardware source.  This system delivers up to 5.4 gygaflops (transfer
rate of one million floating point numbers per second) of maximum performance
and has a 64-bit architecture which enables its servers to support the large
memory and file size requirements of supercomputing environments.  The Company
primarily utilizes Seis Up software under a license with Geocenter, Inc.  Seis
Up is a fully interactive, standards compliant, seismic processing system
designed specifically for processing large volume land and marine 2-D and 3-D
seismic surveys.  Seis Up also offers optimized 3-D parallel processing on
networks or clusters of segregated workstations.

</TABLE>


         In general, estimates of economically recoverable oil and natural gas
reserves or the future net cash flows therefrom are based upon a number of
variable factors and assumptions, such as historical production from the
properties, assumptions concerning future oil and natural gas prices and future
operating costs and the assumed effects of regulation by governmental agencies,
all of which may vary considerably from actual results.  Estimates of the
economically recoverable oil and natural gas reserves attributable to any
particular group of properties based on risk of recovery and estimates of
future net cash flows expected therefrom prepared by different engineers or by
the same engineers at different times, may vary substantially.  The Company's
actual production, revenues, severance and excise taxes and development and
operating expenditures with respect to its reserves will vary from such
estimates, and such variances could be material.

         Estimates with respect to proved reserves that may be developed and
produced in the future are often based upon volumetric calculations and upon
analogy to similar types of reserves rather than actual production history.
Estimates based on these methods are generally less reliable than those based
on actual production history.  Subsequent evaluation of the same reserves based
upon production history will result in variations, which may be substantial, in
the estimated reserves.

         In accordance with applicable requirements of the Securities and
Exchange Commission ("SEC"), the estimated discounted future net cash flows
from estimated proved reserves are based on prices and costs as of the date of
the estimate unless such prices or costs are contractually determined at such
date.  The Company used $17.75 per Bbl of oil and condensate and $2.25 per
MMbtu for natural gas, representing the posted price for West Texas
Intermediate at June 30, 1997, and the average Vinton spot price for June,
respectively.  Actual future prices and costs may be materially higher or
lower.  The June 1997 prices realized averaged $17.48 per Bbl for oil and
condensate and $2.15 per Mcf for gas.  Actual future net cash flows also will
be affected by factors such as actual production, supply and demand for oil and
natural gas, curtailments or increases in consumption by natural gas
purchasers, changes in governmental regulations or taxation and the impact or
inflation on costs.

         Since July 1, 1997, no oil or gas reserve information has been filed
with, or included in any report to, any U.S. authority or agency other than the
SEC and the Energy Information Administration ("EIA").  The basis of reporting
reserves to the EIA for the Company's reserves is identical to that set forth
in the foregoing table.

PRODUCTION AND PRICING

         The Company recognized its first revenues from its oil and gas
operations in fiscal 1997.  Since this was the first production it may not be
indicative of future costs or prices.  Production, average sales prices and
production costs for fiscal 1997 are as follows:

ACREAGE

         The table below sets forth the acreage in which the Company had an
interest at June 30, 1997.  As of June 30, 1996 the Company held 2,480 gross
undeveloped acres and 289 net undeveloped acres.  Developed acreage includes
that assigned to the existing productive wells reflected above.  Undeveloped
acreage is considered to be those leased acres on which wells have not been
drilled or completed to a point that would permit the production of commercial
quantities of oil or gas regardless of whether or not such acreage contains
proved reserves.  The Company's acreage is entirely in Texas and Louisiana.

</TABLE>

CAPITAL REQUIREMENTS

         The Company will require substantial capital expenditures for the
exploration, exploitation and development of its existing properties and any
new ones the Company acquires.  The Company's current level of indebtedness
limits its ability to fully recognize the potential of its existing properties
and to expand its oil and gas operations.  While oil and gas reserves are
expected to increase in fiscal 1998, cash flow from operations will not be
sufficient to fund required capital expenditures.  There can be no assurance
that additional debt or equity financing will be available.

SHORTAGES OF RIGS, EQUIPMENT, SUPPLIES AND PERSONNEL

         There is a general shortage of drilling rigs, equipment and supplies
which the Company believes may intensify.  The costs and delivery times of
rigs, equipment and supplies are substantially greater than in prior periods
and are currently escalating.  Shortages of drilling rigs, equipment or
supplies could delay and adversely affect the Company's exploration and
development operations.

         The demand for, and wage rates of, qualified rig crews have begun to
rise in the drilling industry in response to the increasing number of active
rigs in service.  Such shortages have in the past occurred in the industry in
times of increasing demand for drilling services.  If the number of active rigs
continues to increase, the oil and gas industry may experience shortages of
qualified personnel to operate drilling rigs, which could delay the Company's
planned drilling operations.

REGULATION OF OIL AND NATURAL GAS EXPLORATION AND PRODUCTION

         Exploration and production operations of the Company are subject to
various types of regulation at the federal, state and local levels.  Such
regulation includes requiring permits for the drilling of wells, maintaining
bonding requirements in order to drill or operate wells, and regulating the
location of wells, the method of drilling and casing wells, the surface use and
restoration of properties upon which wells are





                                       11
<PAGE>   12



drilling and the plugging and abandonment of wells.  The Company's operations
are also subject to various conservation laws and regulations.  These include
the regulation of the size of drilling and spacing units or proration units and
the density of wells which may be drilled and unitization or pooling of oil and
gas properties.  In this regard, some states allow the forced pooling or
integration of tracts to facilitate exploration while other states rely on
voluntary pooling of lands and leases.  In addition, some state laws establish
maximum rates of production and some prorate production to market demand.

ENVIRONMENTAL MATTERS

         The Company's operations are subject to federal, state and local laws
and regulation governing the discharge of materials into the environment or
otherwise relating to environmental protection.  Numerous governmental
departments issue rules and regulations to implement and enforce such laws
which are often difficult and costly to comply with and which carry substantial
penalties for failure to comply.  These laws and regulations may require the
acquisition of a permit before drilling commences, restrict the types,
quantities and concentration of various substances that can be released into
the environment in connection with drilling and production activities, limit or
prohibit drilling activities on certain lands lying within wilderness, wetlands
and other protected areas, and impose substantial liabilities for pollution
resulting from the Company's operations.   In addition, these laws, rules and
regulations may restrict the rate of oil and natural gas production below the
rate that would otherwise exist.

RECENT ACTIVITIES

         In the three months ended September 30, 1997 the Company participated
in the drilling of  7 (3.3 net) wells of which 3 (1.3 net) were productive, 3
(1.0 net) were dry and 1 (.1 net) was still being drilled.

         In August 1997 the Company sold 45% of its interest in the Lake Boeuf
prospect for $1,012,500 and a carried interest to casing point in the first 3
wells in that prospect.  This sale reduced the Company's proved undeveloped
reserves by approximately 2,981 MMcfe and the SEC PV10 value by approximately
$1,981,000.

         Substantially all of the Company's assets, including all its oil and
gas properties, are pledged under terms of various financing arrangements.  See
Note 4 to the consolidated financial statements.

ITEM 3.  LEGAL PROCEEDINGS

         From time to time, the Company and its subsidiaries are defendants or
parties in lawsuits or other proceedings arising in the ordinary course of the
Company's business.  Such lawsuits typically relate to claims arising from the
Company's seismic activities.  The Company is not aware of any such proceedings
which it deems to be potentially material.

         The Company was involved in an aborted merger earlier in fiscal 1997
that led to a proxy fight with a group of shareholders that styled themselves
"The Universal Seismic Stockholders' Protective Committee" (the "Stockholders'
Committee").  The proxy fight was resolved at the reconvened Annual Meeting of
Shareholders on February 11, 1997, at which management's slate of directors was
reelected and all of the Stockholders' Committee's proposals were defeated.





                                       12
<PAGE>   13



         Thereafter, Michael T. Kanarellis, one of the members of the
Stockholders' Committee, submitted letters to various members of the Audit
Committee of the Company, alleging that "the Company's financial statements for
the fiscal year ended June 30, 1996 and the fiscal quarters ended September 30,
1996 and December 31, 1996 were false and materially misstated" and alleging
certain specific terms of misstatement. The group also filed a suit against the
Company and its directors styled The Universal Seismic Associates, Inc.,
Stockholders' Protective Committee, Michael T.  Kanarellis, and Robert J.
Kecseg v. Michael J. Pawelek, Ronald L. England, Calvin G. Cobb, Gary Milavec,
Steven Oakes, Rick Trapp, Rimco Associates, L.P. and Resource Investors
Management Company, L.P. v. Universal Seismic Associates, Inc., in the United
States District Court of Delaware.

         All parties entered into a stipulation of Settlement which was
tendered to the Court on August 7, 1997, whereby the RIMCO Partnerships and
their general partner, Resource Investors Management Company Limited
Partnership and its general partner RIMCO Associates, Inc.(all collectively
"RIMCO") agreed to purchase all of the shares of the Company Common Stock owned
by the Stockholders' Committee for an aggregate purchase price of $650,000, or
$3.17 per share.  Also in connection with the settlement, RIMCO entered into a
$2 million loan agreement with the Company, with the proceeds being used to
fund the immediate costs of settlement and to pay other expenses associated
with the lawsuit.  The settlement was approved by the Court on October 1, 1997,
at which time the Court entered judgment dismissing all claims with prejudice.
The Company believes that it will recover a substantial portion of its costs
and expenses associated with the settlement of the lawsuit from its directors'
and officers' liability insurance carrier.

         See Item 6. "Management's Discussion and Analysis of Financial
Condition and Results of Operations" for a description of the effects of this
lawsuit on the Company in the last fiscal year.

ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

OPERATING REVENUE AND COSTS

         The fiscal 1997 revenues of $31,287,329 represent an increase of
approximately 22% over fiscal 1996 revenues of $25,599,121.  The increased
revenues reflect gains in Data Acquisition activities.  Data Acquisition
revenues increased by approximately 23% to $30,015,185 in 1997 due primarily to
a full year of operation of the Company's two most recently added 3-D
acquisition crews.  These crews were placed in service in October 1995 and June
1996, respectively.  Data processing revenues remained relatively constant at
$1,166,100 in fiscal 1996 as compared to $1,158,830 in fiscal 1997.  Oil and
gas revenues for fiscal 1997 were $113,314, which was the first year that the
Company had oil and gas revenues.  The Company does expect oil and gas revenues
to increase in fiscal 1998, although such increase is likely to be limited
because the Company currently lacks sufficient cash to conduct its drilling
activities.

         Operating expenses increased from $25,302,906 to $36,661,381, or
approximately 45%, in fiscal 1997.  Direct costs of Data Acquisition increased
by approximately 36%, from $19,921,200 in 1996 to $27,034,915 in 1997, due to
the Company's expanded crew operations.  Direct costs of Data Processing
increased slightly from $893,715 in 1996 to $905,992 in 1997 as no significant
changes in Data Processing operations took place.  Gross margins before
depreciation for Data Acquisition operations declined to approximately 10% in
fiscal 1997 from approximately 18% in fiscal 1996, due primarily to operational
difficulties with certain seismic crews, increased provision for doubtful
accounts and continued competitive pressure on seismic data acquisition
pricing.  Selling, general and administrative expenses increased approximately
11% from $2,247,845 in 1996 to $2,488,787 in 1997 due primarily to increased
costs of insurance and corporate office operating expenses associated with the
Company's expanded operations.  In 1997 the Company incurred $2,146,313 in
non-recurring expenses related to the aborted Suelopetrol merger and related
proxy contest and shareholder litigation.  The expenses incurred were as
follows:  (i) $301,230 relating to the aborted Suelopetrol merger and (ii)
$1,845,083 of legal, accounting and other costs related to the proxy contest
and subsequent litigation initiated by a shareholder, including uninsured
settlement costs.  Also, in 1997 the Company decided to expense the remaining
portion of the operating lease for its obsolete Opseis 5586 data acquisition
system totaling $929,191.  Depreciation and amortization increased by
approximately 40% from $2,240,146 in 1996 to $3,132,242 due primarily to
equipment additions related to the Company's crew expansion made during fiscal
year 1996.

         Interest expense increased by approximately 24%, from $1,121,969 in
1996 to $1,389,961 in 1997.  The increased interest resulted primarily from
equipment financing for the Company's Data Acquisition expansion and borrowings
for working capital for the expanded operations.

         The Company reported a net loss of $6,171,539, or $(1.23) per share,
for fiscal 1997 as compared to a net loss of $808,857, or $(0.19) per share in
fiscal 1996.  The net loss for fiscal 1997 is after a $559,461 gain on a sale
of leasehold interests by UNEXCO.  The current period net loss was primarily
the result of (i) lower gross margins from Data Acquisition activities that
resulted from less than full utilization of the Company's crews and operational
difficulties on several significant projects, that combined with indirect
overhead, depreciation and interest expenses lead to operating losses, (ii) the
extraordinary expenses associated with the aborted merger and related proxy
fight and shareholder litigation, (iii) the provision for doubtful accounts and
(iv) the obsolescence of the Opseis system.  The proxy fight and shareholder
litigation put additional downward pressure on profits as substantial
management resources were diverted to manage the proxy fight and litigation.
Management also believes that, in some instances, the proxy fight and
shareholder litigation may have resulted in damage to customer and other
relationships which may have resulted in lost business or required the Company
to bid seismic projects more





                                       15
<PAGE>   16



aggressively than in the past to obtain a project.  The proxy fight and
litigation also increased the difficulty of hiring crew personnel which also put
additional pressure on operational efficiency.  Although the Company is
attempting to reduce its operating losses by increasing Data Acquisition
marketing efforts, improving Company and crew management and staffing and
otherwise attempting to increase the efficiency of its seismic crews, it is
anticipated that operations will continue to be conducted at a loss in the near
term.

LIQUIDITY AND CAPITAL RESOURCES

         During fiscal 1997 the Company's cash and cash equivalents increased
by $877,246.  This increase resulted from cash provided by operations of
$1,740,163, proceeds from the sale of assets of $1,494,457 and the proceeds
from a working capital loan totaling $2,000,000.  Capital expenditures of
$7,022,835 during fiscal 1997 include $6,157,051 invested in oil and gas
properties, $606,389 for miscellaneous Data Acquisition equipment and $259,395
for Data Processing equipment.  The Company increased long term debt
obligations by $5,381,685 during 1997.  The Company incurred expenses relating
to the aborted merger, proxy contest and shareholder litigation of $2,146,313
in 1997 of which approximately $602,000 was paid in fiscal 1997 and the
remainder of which will be paid in fiscal 1998.

         In December 1996 UNEXCO entered into a $4,000,000 revolving line of
credit facility with  RIMCO.  In March 1997 the agreement was amended
increasing the revolving line to $5,500,000.  Borrowings under the credit
facility bear interest at 12% per year and mature on December 1, 1999.  On
September 30, 1997 the outstanding balance under this facility was $5,350,000.

         In March 1997 the Company borrowed an additional $2,000,000 from RIMCO
for general working capital purposes.  The facility bears interest at 12% per
year and matures on December 1, 1999.

         In August 1997 the Company borrowed an additional $2,000,000 from
RIMCO.  The proceeds were utilized to fund the shareholder litigation
settlement and legal and accounting fees incurred as of a result of such
litigation.  The Company expects to recover a substantial portion of its costs
of the settlement and expenses associated with the lawsuit from its directors'
and officers' liability insurance carrier.  Any and all proceeds from insurance
reimbursements related to the litigation are required to be applied to amounts
outstanding from the borrowing.  The facility bears interest at 12% per year
and matures on December 1, 1999.

         Also, in August 1997, UNEXCO received $1,012,500 in exchange for the
reduction of its working interest in its Lake Boeuf Prospect from 37.5% to
20.625%.

         The Company's other current liabilities balance increased by
$1,660,388 in the fiscal 1997.  The increase is primarily attributed to a
provision for the shareholder litigation settlement and related expenses in the
amount of $1,205,000 net of the expected recovery from the Company's directors'
and officers' liability insurance carrier and provision for other unresolved
disputes and various other pending litigation.  At June 30, 1997 the Company
had approximately $1,559,000 in trade accounts receivable over 90 days past
due, which as of September 30, 1997 had been reduced to $1,540,000.  The
Company increased its allowance for doubtful accounts receivable to $721,697 in
fiscal year ended June 1997 as compared to $55,000 in fiscal year 1996,
primarily because of unresolved billings with two customers.

         At June 30, 1997 the Company had cash balances of $1,859,677.  As of
September 30, 1997, such cash balances were $698,807.  If losses from
operations continue (as is anticipated), the Company does not believe this
cash, along with anticipated cash flow from its seismic and exploration and
production





                                       16
<PAGE>   17



operations and funds available under its credit facilities, will be adequate
for its overall working capital requirements.  The Company was in default under
certain provisions of its financing agreement for its trade receivables and has
been unsuccessful in obtaining a waiver but is still receiving advances under
the agreement.  The loss of this financing would further aggravate the working
capital situation.  The Company was also in default under covenants in its
RIMCO financing agreements, and RIMCO has waived such defaults until July 1,
1998 and has deferred payments of interest and principal due after June 30,
1997 until December 1, 1997.  The Company also believes that it could generate
substantial cash flow from its oil and gas properties if it had sufficient
funding of its drilling program.  As a result, the Company has engaged Morgan
Keegan to assist it in exploring, developing and recommending various strategic
alternatives to meet its working capital requirements and maximize shareholder
value.  The alternatives may include the possible merger or business
combination of the Company with another entity as well as capital raising or
recapitalization or reorganization strategies.  The Company and Morgan Keegan
are in the process of soliciting and evaluating proposals for such strategic
alternatives.

SECTION 16 (a) COMPLIANCE

         Under Section 16 (a) of the Securities Exchange Act of 1934,
directors, certain officers and beneficial owners of 10% or more of the
Company's Common Stock are required from time to time to file with the SEC
reports on Form 3, 4 or 5, relating principally to transactions in Company
securities by such persons.  Based solely upon review of Forms 3 and 4 and
amendments thereto furnished to the Company during its fiscal year 1996 and
thereafter, Forms 5 and amendments thereto furnished to the Company with
respect to its fiscal year 1996, and any written representations received by
the Company from a director, officer or beneficial owner of more than 10% of
the Common Stock by the Company ("reporting persons") that no Form 5 is
required, the Company believes that the following reporting persons failed to
file on a timely basis the following reports required by Section 16(a) of the
Securities and Exchange Act of 1934 during the Company's fiscal 1997 or prior
years.  Mr. Oakes was elected a director in May 1996, and Mr. Spooner was

and November 10, 1996, respectively.  Mr. England assigned warrants to purchase
105,000 shares of Company stock to Kentex on January 16, 1996, and neither
party filed Form 4 for this change in beneficial ownership.

EMPLOYMENT AGREEMENTS

         The Company has entered into written employment contracts with Michael
J. Pawelek and Ronald L. England for a term of two years beginning March 1,
1995, with automatic renewals for additional terms of two years unless Mr.
Pawelek or Mr. England or the Company give notice at least 60 days prior to the
expiration of the initial term or any renewal term.  These contracts, which
were automatically renewed in accordance with their respective aforedescribed
terms provide for minimum annual salaries of $120,000 for Mr. Pawelek and

his then current salary and annual bonus until the next succeeding December 31
on which the Company could have terminated the term of the contract and (ii)
pay immediately a lump sum equal to the individual's then current annual salary
and the amount of incentive bonus paid or payable for the immediately preceding
year.  Each of the individuals  is also provided an automobile under the terms

CHANGE IN CONTROL

         A number of events have occurred in fiscal 1997 and thereafter which
may effect or have effected a change in control of the Company.  Because the
Company has defaulted on substantially all of its credit facilities, incurred
large operating losses from its data acquisition operation, lacks sufficient
funding for its oil and gas and seismic operations, and has limitations on
sources of additional capital, the Company has retained Morgan Keegan to assist
it in determining its strategic alternatives and developing recommendations to
attempt to maximize shareholder value.  Those recommendations may include the
merger or business combination of the Company with another entity, as well as
capital raising, recapitalization or reorganization alternatives, any of which
may result in a change in control of the Company.

         Since January 1996, RIMCO has been a principal shareholder and lender
and has had two nominees serving on the Board of Directors of the Company.  As
a result of the agreed purchase by RIMCO of 205,300 shares of Common Stock in
connection with the settlement of the shareholder litigation and the conversion
by the Company of $3,500,000 in debt owed by the Company to RIMCO into an
aggregate of 940,962 shares of Common Stock, RIMCO has or will have record
ownership of 1,146,262 shares of Common Stock, or 22% of the issued and
outstanding Common Stock of the Company on October 10, 1997.  RIMCO also has
the right to acquire at an aggregate price of $1,911,350 up to an additional
443,650 shares of Common Stock under currently exercisable warrants, which
could increase RIMCO's holdings to 28% of the issued and outstanding Common
Stock of the Company.   In addition, since June 30, 1996 the Company has
entered into three new credit facilities with RIMCO for an aggregate of
$9,500,000, which when combined with prior RIMCO loans aggregated $18,182,516
at September 30, 1997, or in excess of 90% of the Company's debt at such date.
RIMCO's debt is secured by substantially all of the assets of the Company.  The
Company is in default on numerous material covenants in its credit facilities
with RIMCO, including payment covenants.  RIMCO has waived the Company's
defaults under the covenants (other than payment covenants) until July 1, 1998.
RIMCO has also deferred payments of interest and principal due after June 30,
1997 until December 1, 1997.  RIMCO has waived or modified these covenants to
give the Company additional time and flexibility to pursue the strategic
alternatives described above.

ITEM 12.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

         Transactions between the Company and its officers, directors and
principal stockholders or affiliates of any of them have been and will be on
terms no less favorable to the Company than could be obtained from unaffiliated
third parties.  Approval of a majority of disinterested members of the Board of
Directors will be required for any transaction between the Company and its
officers, directors or affiliates.  Any future loans from the Company to its
officers, directors, key employees or their affiliates will be approved by a
majority of the independent and disinterested directors.

         The Company has performed seismic services for Energy Arrow, for which
Matthew R. Bob, a former director of the Company, is President and an owner.
In fiscal 1996, the Company received approximately $1,683,000 for seismic
services performed for Energy Arrow under various contracts.

         The Company had net unpaid advances of $76,440 due from Sierra
Management, Inc., a company partially owned by Messrs. Pawelek and England, as
of July 1, 1995.  This amount was repaid by payments of $48,000 and $28,440 on
September 30, 1995 and 1996, respectively.  Payments were without interest.

         On February 1, 1996, the Company entered into a consulting agreement
with Mr. Billy E. Trapp, the former President of the Company who retired from
full time employment in March 1991 (the "Billy





                                       23
<PAGE>   24



Trapp Consulting Agreement").  Pursuant to the Billy Trapp Consulting
Agreement, the Company pays Mr. Trapp $4,000 per month for his services as a
consultant to the Company for a term of ten years, provided that the Company
may terminate the agreement for good cause.  In connection with the Billy Trapp
Consulting Agreement, Mr. Trapp and his wife executed a release agreement
whereby each jointly and severally released the Company, Sierra and their
respective affiliates, officers, directors, employees and representatives from
any liabilities or claims related to a certain letter agreement regarding
advisory and consulting services dated February 14, 1992 between Mr. Trapp and
the Company, a certain letter agreement for consulting services, stock
assignment, termination of stock options and group life insurance coverages
dated February 14, 1992 by Mr. Trapp, with a joinder by Mrs. Trapp, and any
other agreements or relationships between Mr. Trapp and/or Mrs. Trapp and the
Company and/or Sierra.  In connection with amending the consulting agreement,
the Company issued Mr. Trapp warrants to purchase 37,500 shares of common stock
at $3.75 per share.  Billy E. Trapp is the father of Rick E. Trapp, the
Company's former Chief Executive Officer and Chairman of the Board.

         On December 15, 1994, the Company entered into a consulting agreement
with Rick E. Trapp, the former Chief Executive Officer and Chairman of the
Board of Directors, for a term of three years (the "Rick Trapp Consulting
Agreement").  The Rick Trapp Consulting Agreement provided for (i) a monthly
fee of $10,000 to be paid to Mr. Trapp, and (ii) a covenant not to engage in
certain activities in competition with the Company for a period of six months
following termination of the agreement.  On September 22, 1996, Mr. Trapp and
the Company agreed to terminate the Rick Trapp Consulting Agreement.  In
connection therewith (i) the Company agreed to pay to Mr. Trapp the sum of
$40,000, payable in four equal monthly installments commencing on October 1,
1996, and (ii) Mr. Trapp executed a release and waiver agreement pursuant to
which Mr. Trapp agreed to release the Company and its affiliates, officers,
directors, employees and representatives from any and all liability and claims
related to Mr. Trapp's employment with the Company, the termination of Mr.
Trapp's employment, the Rick Trapp Consulting Agreement and any other
agreements and relationships between the Company and Mr. Trapp.  The Company
has agreed to pay up to $40,000 for income tax planning related to Kentex and
Sierra in connection with the termination of Mr. Trapp's consulting agreement.
The release and waiver agreement further provided that Mr. Trapp not compete
with the Company nor solicit any employee, agent or representative of the
Company for a period of one year thereafter.  The Company paid Mr. Trapp for
four additional months as a result of work performed by him (a total of
$110,000 in fiscal 1997).

         On January 19, 1996, the Company entered into a financing arrangement
with RIMCO providing up to $7,000,000, of which $4,000,000 was immediately
funded, to restructure existing debt.  Messrs. Oakes and Milavec are employees
of RIMCO.  The debt restructure consisted of (i) $3,500,000 in 10% Senior
Secured General Obligation Notes payable in 48 equal monthly installments of
principal plus interest (payments due after June 30, 1997, extended to December
1, 1997), and (ii) $500,000 in 5% Convertible Notes maturing on February 1,
1998, with monthly payments of interest, convertible into common stock of the
Company (the "Convertible Notes") at a conversion price of $3.45 per share,
subject to adjustment. The remaining $3,000,000 was subsequently funded under
10% Senior Secured Exchangeable General Obligation Notes, which were
exchangeable for common stock of the Company (the "Exchangeable Notes") at an
exchange price of $3.77 per share, subject to adjustment.  The proceeds were
used to finance the Company's exploration and production activities.  In
connection with this financing arrangement, the Company issued to RIMCO
warrants to purchase 165,000 shares of the Company's common stock at a purchase
price of $3.14 per share, subject to adjustment.  On August 14, 1996, the
Company exercised its right to convert the Convertible Notes into 145,208
shares of the common stock of the Company.  On September 30, 1996, the Company
exercised its right to exchange the Exchangeable Notes for 795,754 shares of
the Company's common stock.

         On May 28, 1996, the Company entered into an additional credit
facility with RIMCO pursuant to which the Company issued 10% Senior Secured
General Obligation Notes in the aggregate principal

amount of $6,500,000.  The proceeds were used to acquire new seismic equipment
and retire some existing debt.  The notes provide for monthly payments of
interest only until December 1, 1996 (all payments after June 30, 1997 have
been extended to December 1, 1997), then $138,106, including interest, with the
balance due December 1, 1999, and are secured by the Company's seismic
equipment.  In connection with this credit facility, the Company issued to
RIMCO warrants to purchase 278,650 shares of the Company's common stock at a
purchase price of $5.00 per share, subject to adjustment.

         On December 20, 1996, the Company entered into another financing
agreement with RIMCO to provide $4,000,000 (increased to $5,500,000 on March
27, 1997)  under a revolving credit facility for the expansion of the Company's
exploration and production activities ($5,350,000 outstanding at June 30,
1997).  RIMCO has the right of approval on any property that funds are advanced
toward.  In connection with this revolving credit facility, the Company issued
12% Senior Secured General Obligation Notes with interest payable monthly
(interest due after June 30, 1997 has been extended to December 1, 1997) and
the principal due December 1, 1999.  The notes are secured by the Company's oil
and gas properties.

         On March 27, 1997 the Company borrowed an additional $2,000,000 from
RIMCO under new 12% Senior Secured General Obligation Notes with interest
payable monthly (interest due after June 30, 1997 has been deferred to December
1, 1997) and principal due December 1, 1999.  The proceeds were used for
working capital.  The notes are secured by the Company's seismic equipment.

         On August 6, 1997 the Company borrowed an additional $2,000,000 from
RIMCO under another 12% Senior Secured General Obligation Note, also secured by
the Company's seismic equipment, with interest payable monthly (extended to
December 1, 1997) and principal due December 1, 1999.  The proceeds were used
to fund the shareholder settlement described under "Legal Proceedings".

         Employees of RIMCO introduced the Company to the operator of the Lake
Boeuf and East Holly Beach prospects, and on April 17, 1996, the Company
entered into agreements to acquire an interest in both prospects.  On May 14,
1996 the Company and RIMCO entered into an agreement for RIMCO to pay the
Company for 25% of its costs incurred and to participate on the same basis as
the Company as to 25% of the Company's then interest in the two prospects.  In
August the Company sold a portion of its remaining interest in the Lake Boeuf
prospect to an unaffiliated party.  The Company and affiliates of RIMCO also
participate in the West Refugio prospect as non-operator, on similar terms.

         RIMCO has waived the Company's defaults under the covenants in its
various financing agreements until July 1, 1998.  It has also deferred payments
of interest and principal due after June 30, 1997 until December 1, 1997.  As
of September 30, 1997 the Company was indebted to RIMCO under the various
financing agreements for $18,182,516 principal and $501,830 accrued interest.

         The Company and Brigham Exploration Company both participate in the
Southwest Danbury prospect.  Mr. Milavec is a director of both companies.

         As of March 1, 1997 the Company entered into an agreement with
Corstone Corporation ("Corstone"), a business in which Calvin G. Cobb is a
managing director, to provide investor relations and corporate communication
services.  The term of the agreement is one year and provides for a monthly fee
of $9,500.

         The shareholder litigation described in Item 3. "Legal Proceedings"
involved claims against the individual directors, in addition to the Company
itself, all of which were settled by the Company on behalf of itself and its
directors.  The Company paid approximately $1.85 million in legal, accounting
and other costs to defend the lawsuit, a portion of which it believes may
eventually be recovered from its directors' and officers' liability insurance
carrier.

FORWARD-LOOKING STATEMENTS

         Statements included in this report which are not historical facts
(including any statements concerning plans and objectives of management for
future operations or economic performance, or assumptions related thereto) are
forward-looking statements within the meaning of Section 21E of the Securities
Exchange Act of 1934, as amended, and Section 27A of the Securities Act of
1933, as amended.  In addition, the Company and its representatives may from
time to time make other oral or written statements which are also
forward-looking statements.

         Such forward-looking statements include, among other things,
statements regarding development activities, capital expenditures, acquisitions
and dispositions, drilling and exploration programs, projected quantities of
future oil and gas production, costs and expenditures as well as projected
demand for seismic acquisition and processing services and oil and gas, which
will affect sales levels, prices and margins realized by the Company.

         These forward-looking statements are made based upon management's
current plans, expectations, estimates, assumptions and beliefs concerning
future events impacting the Company and, therefore, involve a number of risks
and uncertainties.  The Company cautions that forward-looking statements are
not guarantees and that actual results could differ materially from those
expressed or implied in the forward-looking statements.

         Important factors that could cause the actual results of operations or
financial condition of the Company to differ include, but are not necessarily
limited to: the cost of finding and successfully developing oil and gas
reserves, production levels of its seismic crews, the demand for the Company's
3-D seismic data acquisition and processing services, the price for which such
reserves and services can be sold, the volatility of commodity prices for oil
and gas, the inability to raise new capital through financings or sale of
interests in its oil and gas properties, unanticipated geological problems, the
occurrence of unusual weather or operating conditions including force majeure,
the failure of equipment or processes to operate in accordance with
specifications or expectations, delays in anticipated start-up dates,
environmental risks affecting the drilling and producing of oil and gas wells,
the timing of receipt of necessary governmental permits, labor relations and
costs, accidents, changes in governmental regulation or enforcement practices,
risks and uncertainties relating to general domestic and international economic
(including inflation and interest rates) and political conditions, the
experience and financial condition of joint venture partners and changes in
financial market conditions.  Many of such factors are beyond the Company's
ability to control or predict.  Readers are cautioned not to put undue reliance
on forward-looking statements.

         While the Company periodically reassesses material trends and
uncertainties affecting the Company's results of operations and financial
condition in connection with the preparation of Management's Discussion and
Analysis of Results of Operations and Financial Condition and certain other
sections contained in the Company's quarterly, annual and other reports filed
with the Securities and Exchange Commission, the Company does not intend to
publicly review or update any particular forward-looking statement, whether as
a result of new information, future events or otherwise.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Stockholders and
Board of Directors of
Universal Seismic Associates, Inc.:



We have audited the accompanying consolidated balance sheet of Universal
Seismic Associates, Inc. and Subsidiaries as of June 30, 1997 and 1996, and the
related consolidated statements of operations, stockholders' equity and cash
flows for the years then ended. The consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatements. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of
Universal Seismic Associates, Inc. and Subsidiaries as of June 30, 1997 and
1996, and the consolidated results of their operations and their cash flows for
each of the two years in the period ended June 30, 1997, in conformity with
general accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 10 to the
financial statements, the Company has incurred significant losses and has a
working capital deficit that raise substantial doubt about its ability to
continue as a going concern. Management's plan in regard to these matters is
also described in Note 10. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

UNIVERSAL SEISMIC ASSOCIATES, INC AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.       SUMMARY OF SIGNIFICANT ACCOUNTING PRINCIPLES:

         Organization and Principles of Consolidation

         Universal Seismic Associates, Inc. and subsidiaries (the "Company")
         are engaged primarily in land geophysical services. These services
         include the contract acquisition of three-dimensional seismic data,
         the processing and reproduction of seismic data and survey services.
         The Company also participates in oil and gas exploration, development,
         and production activities. The consolidated financial statements are
         presented after all significant intercompany accounts and transactions
         have been eliminated.

         Revenue Recognition

         The Company recognizes revenue on fixed price contracts on the basis
         of percentage of completion with no profit recognized until sufficient
         progress has been made to adequately assess the estimate of profit
         recognition. When estimated total costs on any contract indicates a
         loss, the entire amount of the loss is recognized immediately.

         Property and Equipment

         Property and equipment, other than oil and gas properties, are stated
         at cost and are depreciated on the straight-line method over the
         estimated useful lives of the assets, which range from three to ten
         years. Equipment under capital leases is stated at the present value
         of future minimum lease payments at the inception of the lease and is
         amortized on the straight-line method over the shorter of the
         estimated useful life of the assets, which range from five to ten
         years, or the term of the lease. Maintenance and repairs are charged
         against income when incurred, and renewals or betterments are
         capitalized. Upon retirement or other disposal of fixed assets, the
         cost and related accumulated depreciation are removed from the
         respective accounts, and any gains or losses are included in results
         of operations. The Company had fully depreciated property and
         equipment which was still being utilized in the amounts of $543,000
         and $502,000 at June 30, 1997 and June 30, 1996, respectively.

         The Company uses the full cost method of accounting for oil and gas
         activities. Under this method of accounting, all costs incurred in the
         acquisition, exploration, and development of oil and gas properties,
         including costs incurred by the Company's own data acquisition
         subsidiary, are capitalized. Such capitalized costs and estimated
         future development and dismantlement costs are amortized on a
         unit-of-production method based on proved reserves. Net capitalized
         costs of oil and gas properties are limited to the lower of unamortized
         costs or the cost center ceiling, defined as the sum of the present
         value (10% discount rate) of estimated unescalated future net revenues
         from proved reserves; plus the cost of properties not being amortized,
         if any; plus the lower of cost or estimated fair value of unproved
         properties included in the costs being amortized, if any; less related
         income tax effects. Disposition of oil and gas properties are recorded
         as adjustments to capitalized costs, with no gain or loss recognized
         unless such adjustments would significantly alter the relationship
         between capitalized costs and proved reserves. A large portion of the
         capitalized costs related to the Company's oil and gas activities are
         created by the Company's data acquisition business. All intercompany
         profit has been eliminated. During the first quarter of fiscal 1997,
         the Company sold a portion of its only property with proved reserves,
         at the time, and recognized a gain of $559,461.





                                      F-6
<PAGE>   40

         Unevaluated properties and associated costs not being amortized and
         included in oil and gas properties were $3,791,033 and $1,722,847 at
         June 30, 1997 and 1996, respectively. The properties represented by
         these costs were at such dates undergoing exploration or development
         activities, or are properties on which the Company intends to commence
         such activities in the future, assuming sufficient funding is 
         available.  The Company believes that the unevaluated properties at 
         June 30, 1997 will be substantially evaluated and therefore subject to
         amortization in 12 to 24 months. During fiscal 1997, the Company had 
         $245,203 of capitalized interest relating to unevaluated properties.

         Goodwill

         The excess of the purchase price over the estimated fair value of net
         assets acquired is included in goodwill and is amortized on a
         straight-line basis over fifteen years. At each balance sheet date,
         management assesses whether there has been a permanent impairment in
         the value of goodwill by comparing anticipated undiscounted future
         cash flows from operating activities with the carrying value of the
         goodwill. Other factors considered by management in this assessment
         include operating results, trends and prospects, as well as the
         effects of obsolescence, demand, competition, and other economic
         factors. All goodwill is related to the Company's data processing
         operation.

         Deferred Financing Costs

         Costs incurred in connection with the issuance of the Company's
         long-term debt and notes payable are capitalized and amortized over
         the terms of the respective borrowings using a method which
         approximates the interest method. Accumulated amortization relating to
         deferred financing costs totaled $125,480 and $67,313 at June 30, 1997
         and 1996 respectively.

         Income Taxes

         The Company follows the asset and liability method in accounting for
         income taxes. Under this method, deferred tax assets and liabilities
         are recorded for the estimated future tax consequences attributable to
         the difference between the financial carrying amounts of existing
         assets and liabilities and their respective tax basis. Deferred tax
         assets and liabilities are measured using the tax rate in effect for
         the year in which those temporary differences are expected to turn
         around. The effect of a change in tax rates on deferred tax assets and
         liabilities is recognized in the year of the enacted rate change.

         Earnings Per Share

         Primary earnings per share are based upon the weighted average number
         of outstanding shares of common stock during the respective years.
         Fully diluted earnings per share is not presented because such amounts
         would be antidilutive.

         In February 1997, the Financial Accounting Standards Board issued
         Statement of Financial Accounting Standards No. 128, Earnings Per
         Share, ("SFAS 128"). This Statement specifies the computation,
         presentation and disclosure requirements for Earnings Per Share. This
         statement is effective for financial statements for both interim and
         annual periods ending after December 15, 1997. The Company does not
         expect the adoption of SFAS 128 to have a significant impact on its
         calculation of earnings per share.

         Management Estimates

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities as of
         the date of the financial statements and the reported amounts of
         revenues and expenses during the reported 





                                      F-7
<PAGE>   41

         period. The Company's most significant estimates are based on
         uncompleted seismic acquisition contracts and remaining proved oil
         and gas reserves. See Supplemental Oil and Gas Disclosures in Note
         11. While it is believed that such estimates are reasonable, actual
         results could differ from those estimates due to uncertainties
         inherent in the estimation process.

         Reclassifications

         Certain reclassifications for the prior year have been made to conform
         with the current year presentation, but the net loss for fiscal 1996
         did not change.

         Stock Based Compensation

         In October 1995, the FASB issued Statement of Accounting Standards No.
         123 ("SFAS No. 123"), "Accounting for Stock-Based Compensation" which
         is effective for the Company beginning July 1, 1996. SFAS No. 123
         permits, but does not require, a fair-value-based method of accounting
         for employee stock option plans which results in compensation expense
         being recognized in the results of operations when stock options are
         granted. The Company plans to continue to use the current
         intrinsic-value-based method of accounting for such plans where no
         compensation expense is recognized. See Note 6 for the pro forma
         disclosure of net income and earnings per share as if the
         fair-value-based method of accounting had been applied.

         Concentration of Credit Risk

         The Company maintains deposits in a bank which may exceed the amount
         of federal deposit insurance available. Management periodically
         assesses the financial condition of the institution and believes that
         any possible deposit loss is minimal. The Company has not experienced
         such losses in the past.

         The Company operates primarily in the southern United States and
         grants credit to substantially all of its customers, which are
         primarily independent oil and gas exploration, production and service
         companies. The Company performs on-going credit evaluations of its
         customers and generally does not require collateral for accounts
         receivable. The Company recorded allowances for doubtful accounts
         totaling $721,697 and $55,000 at June 30, 1997 and 1996, respectively.
         The increase at June 30, 1997 was primarily the result of unresolved
         billings with two customers.

         Four customers accounted for approximately 63% of gross accounts
         receivable at June 30, 1997 compared to the three largest accounting
         for 42% at June 30, 1996. No other customer accounted for more than
         10% of receivables at either date.

         Major Customers

         The Company's mix of customers changes yearly as contracts are awarded
         and completed. The Company is unable to anticipate whether significant
         portions of its future revenues may be attributable to a few
         customers, although it is likely the customer mix will change from
         year to year. In fiscal 1997 one customer accounted for 30% of the
         Company's revenues while another accounted for 14%. In fiscal 1996 the
         Company had no revenue from the above customers but 11% of its revenue
         was from one customer with less than 1% of fiscal 1997 revenues.

         On January 19, 1996, the Company entered into a financing arrangement
         with Resource Investors Management Company and four partnerships of
         which it is the general partner (collectively "RIMCO") providing up to
         $7,000,000, of which $4,000,000 was immediately funded to restructure
         existing debt. The debt restructure consisted of (i) $3,500,000 in 10%
         Senior Secured General Obligation Notes payable in 48 equal monthly
         installments of principal plus interest, and (ii) $500,000 in 5%
         Convertible Notes maturing on February 1, 1998, with monthly payments
         of interest, convertible into common stock of the Company (the
         "Convertible Notes") at a conversion price of $3.45 per share, subject
         to adjustment. The remaining $3,000,000 was subsequently funded under
         10% Senior Secured Exchangeable General Obligation Notes, which were
         exchangeable for common stock of the Company (the "Exchangeable
         Notes") at an exchange price of $3.77 per share, subject to
         adjustment. The proceeds were used to finance the Company's
         exploration and production activities. In connection with this
         financing arrangement, the Company issued to RIMCO warrants to
         purchase 165,000 shares of the Company's common stock at a purchase
         price of $3.14 per share, subject to adjustment. On August 14, 1996,
         the Company exercised its right to convert the Convertible Notes into
         145,208 shares of the common stock of the Company. On September 30,
         1996, the Company exercised its right to exchange the Exchangeable
         Notes for 795,754 shares of the Company's common stock.

         On May 28, 1996, the Company entered into an additional credit
         facility with RIMCO pursuant to which the Company issued 10% Senior
         Secured General Obligation Notes in the aggregate principal amount
         $6,500,000. The proceeds were used to acquire new seismic equipment
         and retire some existing debt. The notes provide for monthly payments
         of interest only until December 1, 1996 (extended to December 1,
         1997), then $138,106, including interest, with the balance due
         December 1, 1999. In connection with this credit facility, the Company
         issued to RIMCO warrants to purchase 278,650 shares of the Company's
         common stock at a purchase price of $5.00 per share, subject to
         adjustment.

         On December 20, 1996, the Company entered into another financing
         agreement with RIMCO to provide $4,000,000 (increased to $5,500,000 on
         March 27, 1997) under a revolving credit facility for the expansion of
         the Company's exploration and production activities ($5,350,000
         outstanding at June 30, 1997). RIMCO has the right of approval on any
         property that funds are advanced toward. In connection to this
         revolving credit facility, the Company issued 12% Senior Secured
         General Obligation Notes with interest payable monthly (interest due
         after June 30, 1997 has been extended to December 1, 1997) and the
         principal due December 1, 1999. The notes are secured by the Company's
         oil and gas properties.

         On March 27, 1997 the Company borrowed an additional $2,000,000 from
         RIMCO under new 





                                     F-11
<PAGE>   45

         12% Senior Secured General Obligation Notes with interest payable
         monthly (interest due after June 30, 1997 has been deferred to
         December 1, 1997) and principal due December 1, 1999. The proceeds
         were used for working capital. The notes are secured by the Company's
         seismic equipment.

         On August 6, 1997 the Company borrowed an additional $2,000,000 from
         RIMCO under another 12% Senior Secured General Obligation Note, also
         secured by the Company's seismic equipment, with interest payable
         monthly (extended to December 1, 1997) and principal due December 1,
         1999. The proceeds were used to fund the shareholder settlement
         described in Note 9.

         These loan agreements obtained from RIMCO described above have
         numerous covenants, the most restrictive of which require the Company
         to maintain earnings before depreciation, amortization and interest of
         greater than $2,000,000 through August 31, 1996, and greater than
         $2,500,000 thereafter. The Company must also maintain a current ratio,
         as defined by the note agreements, greater than 0.75 to 1.0 through
         September 30, 1996, and 1.00 to 1.00 thereafter. In addition, the
         Company must maintain a tangible net worth, as defined by the note
         agreements, of greater than $6,000,000 through September 30, 1996, and
         $7,000,000 thereafter. As of June 30, 1997, the Company was not in
         compliance with several of the covenants. RIMCO has waived the
         Company's defaults under the covenants in the various financing
         agreements until July 1, 1998. It has also agreed to defer payments of
         interest and principal due after June 30, 1997 until December 1, 1997.
         As of September 30, 1997 the Company was indebted to RIMCO under the
         various financing agreements for $18,182,516 principal and $501,830
         accrued interest.

         The Company has a $5,000,000 revolving line of credit with a financial
         institution for the financing of its trade receivables. This agreement
         provides the Company must maintain a minimum net worth of $3,000,000
         and annual earnings before interest, taxes, depreciation and
         amortization of at least $500,000, plus certain other covenants. The
         Company was not in compliance with certain provisions of the agreement
         and has been unsuccessful in obtaining a waiver; however, the Company
         still receives advances under the arrangement.

         The Company leases a 720 channel OPSEIS 5586 telemetry acquisition
         system under an operating lease through March 2000. Due to the
         recording limitations of this system, the Company believes it has
         become non-competitive in the 3-D data acquisition market. The system
         has not operated since October 1996 and the Company recognized the
         remaining $929,121 of lease payments in the fourth quarter of fiscal
         1997. The current portion of this obligation is included in other
         current liabilities.

         The weighted average interest rate on short-term borrowings at June
         30, 1997 was approximately 8.21%.


5.       COMMITMENTS AND CONTINGENCIES:

         Lease Commitments

         The Company leases certain seismic equipment, vehicles and office
         facilities under operating leases. The future minimum lease payments
         under the Company's noncancelable operating leases are as follows:

                  Year ending June 30,
                           1998                      $  1,514,903

                           2001                           216,132
                           2002                           216,132
                           Thereafter                     612,374
</TABLE>

         Total rental expense under the Company's  various operating leases for
         the years ended June 30, 1997 and 1996 were $2,480,271 and $2,291,746,
         respectively.

         Contingencies

         The Company has in dispute approximately $850,000 of charges from a
         supplier of services. The supplier billed for approximately $1,075,000
         in fiscal 1997 and $3,090,000 in fiscal 1996. The Company believes
         certain of the charges are inappropriate and that it has substantial
         offsets for additional costs the Company incurred when the supplier
         left a job before it was complete. The Company believes that it has
         provided sufficient liability in its financial statements to cover the
         disputed amounts.

         The Company is involved in various claims and legal actions arising in
         the ordinary course of business. In the opinion of management, the
         ultimate disposition of these matters will not have a material adverse
         effect on the Company's consolidated financial condition. The
         resolution in any reporting period of one or more of these matters in
         a manner adverse to the Company could have a material impact on the
         Company's results of operations and cash flows for that period.

         The Company has employment contracts with certain of its officers and
         key employees for periods up to two years that generally provide for
         automatic renewals unless notice is given within a specified period.
         Some of the contracts provide for a one year period of continued
         employment with no reduction in compensation or benefits in the event
         of a merger, sale of substantially all of the assets or a change in
         control.

         As of January 1, 1996 the Company adopted a 401 (k) qualified
         retirement plan. The Company makes matching contributions in an amount
         equal to 50% of an employee's contribution up to 6%. The Company's
         expense was $55,600 in fiscal 1997 and $15,883 in fiscal 1996.

         See Note 9 regarding a shareholder suit brought during fiscal 1997 and
         settled subsequent to June 30, 1997.

6.       STOCKHOLDERS' EQUITY:

         Stock Option Plans

         The Company has three stock option plans, two for employees and one
         for non-employee Directors (the "Plans") under which an aggregate of
         555,000 shares of common stock are reserved for issuance pursuant to
         the Plans. The Plans are administered by the Board of Directors or a
         committee appointed by the Board of Directors (the "Plan
         Administrator"). The Plan Administrator determines, subject to the
         provisions of the Plan, the employees to whom options 





                                     F-13
<PAGE>   47

         are granted and the number of options to be granted. The Plan
         Administrator may grant (i) "incentive stock options" within the
         meaning of Section 422 of the Internal Revenue Code of 1986 and (ii)
         "non-qualified stock options" (options which do not meet the
         requirements of Section 422).

         Incentive stock options and non-qualified options granted under the
         Plans must have an exercise price equal to at least the fair market
         value of the common stock at the date the option is granted. Each
         option granted under the Plans may have a term of up to ten years,
         except that incentive stock options granted to a stockholder who, at
         the time of the grant, owns more than 10% of the voting stock of the
         Company, may have a term of up to only five years. The exercise price
         of options granted to stockholders possessing more than 10% of the
         total combined voting power of all classes of stock of the Company
         must not be less than 110% of the fair market value of such stock on
         the date of grant and options granted under the non-employee plan
         provides that the price of grants be 125% of the fair market value on
         the date of grant. Options granted under the plans have generally been
         fully exercisable after the grant.

         A summary of stock option transactions during the two years ended June
         30, 1997 is as follows:

         Warrants

         As of June 30, 1997 there were 783,650 Common Share warrants 
         outstanding all of which are exercisable at June 30, 1997 at prices
         ranging from $2.50 to $9.11. Of this, 120,000 warrants are held by 
         directors and are, therefore, included in the following pro forma
         disclosure.

         The Company applies the intrinsic value method for reporting
         compensation expense pursuant to Accounting Principles Board Option
         No. 25 "Accounting for Stock Issued to Employees" to its stock-based
         compensation plans (including certain warrants). Accordingly, no
         compensation expense has been recognized for awards granted under
         these plans. Had compensation expense for the Company's stock-based
         compensation plans been determined in accordance with the fair value
         method pursuant to SFAS No. 123 "Accounting for Stock-based
         Compensation", the Company's pro forma net income and earnings per
         share for the years ended June 30, 1997 and 1996, would have been as
         follows:

         The fair value of the options and warrants granted during fiscal 1996
         (none granted in fiscal 1997) is estimated on the date of grant using
         the Black-Scholes option-pricing model with the following weighted-
         average assumptions: a) no dividends paid, b) expected volatility of
         51.21%, c) risk-free interest rate ranges from 5.13% to 6.25% and d)
         expected life of options is 5 years for 10-year options and 2.5 years
         for 5-year warrants.
        
         The effects of applying SFAS No. 123 in this pro forma disclosure are

         The Company has tax net operating loss carryforwards of approximately
         $15,367,000 available to offset future federal taxable income which
         will expire if not used in fiscal years 2007 through 2012.

         Under federal tax law, the amount of availability of loss
         carryforwards (and certain other tax attributes) are subject to a
         variety of interpretations and restrictive tests applicable to the
         Company and its subsidiaries. The utilization of such carryforwards
         could be limited or effectively lost upon certain changes in
         ownership. Accordingly, while the Company believes substantial loss
         carryforwards are available to it, no assurance can be given
         concerning such loss carryforwards or whether such loss carryforwards
         will be available in the future.

         The Company has provided for a full valuation allowance as it is
         uncertain as to whether the Company will be able to utilize all of its
         net operating loss carryforwards. The Company has not provided for
         federal income taxes for 1997 and 1996 due to the lack of taxable
         income in the carryback period and the fully reserved net deferred tax
         asset related to the net operating loss carryforwards.

8.       RELATED PARTY TRANSACTIONS:

         The Company has a consulting agreement with its founder, which
         requires payments to such individual of $4,000 per month through
         February 1, 2006. In connection with the consulting agreement, the
         Company issued the founders warrants to purchase 37,500 shares of the
         Company's Common Stock at $3.75 per share. The Company also had an
         agreement with its former chairman of the board, which required
         payments to such individual of $10,000 per month, which terminated in
         fiscal 1997. The Company has agreed to pay up to $40,000 for income
         tax planning related to former chairman's common stock holdings of the
         Company.

         The Company has entered into various contracts to perform seismic
         services for a company whose president and owner is a former director
         of the Company. Approximately $1,683,000 in seismic services were
         provided to this company during fiscal 1996. In March 1997 the Company
         entered into a one year agreement with the employer of a director to
         provide investor relations and corporate communication services for a
         monthly fee of $9,500.

         The Company has several transactions with RIMCO as set forth in the
         following paragraphs.

         Two of the Company's directors are employees of RIMCO, in accordance
         with terms of financing agreements with RIMCO they have the right to
         designate two directors.

         As of June 30, 1997 the Company owed RIMCO an aggregate of $16,182,516
         under various financing arrangements as described in Note 4, plus
         $24,518 of accrued interest. Subsequent to June 30, 1997 RIMCO loaned
         the Company an additional $2,000,000 in connection with the settlement
         of a shareholder lawsuit described in Note 9.

         The Company and RIMCO participate in three oil and gas prospects on
         similar terms. RIMCO may approve all oil and gas prospects to which
         the Company commits under terms of certain of the financing
         arrangements.

         According to information furnished to the Company by RIMCO, they owned
         940,963 shares of the Company's common stock at June 30, 1997 (18% of
         the shares outstanding). In the





                                     F-16
<PAGE>   50

         settlement of the shareholder lawsuit described in Note 9, RIMCO has
         the obligation to acquire, under certain conditions, 205,300
         additional shares. RIMCO also holds warrants to purchase 443,650
         additional shares (see Note 4). If the shares were acquired and the
         warrants were exercised RIMCO could increase its holding to 28% of the
         shares outstanding.

9.       SHAREHOLDER LITIGATION AND SUBSEQUENT EVENT:

         The Company was involved in an aborted merger earlier in fiscal 1997
         that led to a proxy fight with a group of shareholders that styled
         themselves "The Universal Seismic Stockholders' Protective Committee"
         (the "Stockholders' Committee"). The proxy fight was resolved at the
         reconvened Annual Meeting of Shareholders on February 11, 1997, at
         which management's slate of directors was reelected and all of the
         Stockholders' Committee's proposals were defeated.

         Thereafter, Michael T. Kanarellis, one of the members of the
         Stockholders' Committee, submitted letters to various members of the
         Audit Committee of the Company, alleging that "the Company's financial
         statements for the fiscal year ended June 30, 1996 and the fiscal
         quarters ended September 30, 1996 and December 31, 1996 were false and
         materially misstated" and alleging certain specific items of
         misstatement. The groups also filed a suit against the Company and its
         directors styled The Universal Seismic Associates, Inc. Stockholders'
         Protective Committee, Michael T. Kanarellis, and Robert J. Kecseg v.
         Michael J. Pawelek, Ronald L. England, Calvin G. Cobb, Gary Milavec,
         Steven Oakes, Rick Trapp, Rimco Associates, L.P. and Resource
         Investors Management Company, L.P. v. Universal Seismic Associates,
         Inc., in the United States District Court in Delaware.

         All parties entered into a stipulation of Settlement which was
         tendered to the Court on August 7, 1997, whereby affiliates of RIMCO
         agreed to purchase all of the shares of the Company Common Stock owned
         by the Stockholders' Committee for an aggregate purchase price of
         $650,000, or $3.17 per share. Also in connection with the settlement,
         affiliates of RIMCO entered into a $2 million loan agreement with the
         Company, with the proceeds being used to fund the immediate costs of
         settlement and to pay other expenses associated with the lawsuit. The
         settlement was approved by the Court on October 1, 1997, at which time
         the Court entered judgment dismissing all claims with prejudice. The
         Company believes that it will recover a substantial portion of its
         costs of settlement and expenses associated with the lawsuit from its
         directors' and officers' liability insurance carrier.

10.      LIQUIDITY:

         The financial statements have been prepared assuming the Company will
         continue as a going concern. A number of events have occurred in
         fiscal 1997 and thereafter which raise doubt about the Company's
         ability to continue as a going concern and may effect or have effected
         a change in control of the Company. Because the Company has defaulted
         on substantially all of its credit facilities, see Note 4, incurred
         large operating losses from its data acquisition operation, has a
         working capital deficit of approximately $2.3 million, lacks
         sufficient funding for its oil and gas and seismic operations, and has
         limitations on sources of additional capital, the Company has retained
         Morgan Keegan to assist the Company in determining its strategic
         alternatives and developing recommendations to attempt to maximize
         shareholder value. Those recommendations may include the merger or
         business combination of the Company with another entity, as well as
         capital raising, recapitalization or reorganization alternatives, any
         of which may result in a change in control of the Company. There is no
         assurance that the Company will be successful in these efforts.

11.      SUPPLEMENTAL OIL AND GAS DISCLOSURES (UNAUDITED):

         The supplementary information regarding the Company's oil and gas
         activities is presented in accordance with the requirements of the
         Securities and Exchange Commission ("SEC") and the Statement of
         Financial Standards No. 69.

         Reserve quantities and future production are based primarily upon the
         reserve report of the independent oil and gas engineering firm of
         Netherland, Sewell & Associates, Inc. based on data supplied to them
         by the Company.

         Reserve quantities and future production are based primarily upon the
         reserve report of the independent oil and gas engineering firm of
         Netherland, Sewell & Associates, Inc.

         Proved oil and gas reserves are the estimated quantities of crude oil,
         condensate and natural gas that geological and engineering data
         demonstrate with reasonable certainty to be recoverable in future
         years from known reservoirs under existing economic and operating
         conditions at the end of the respective years. Proved developed oil
         and gas reserves are those reserves expected to be recovered through
         existing equipment and operating methods. All reserves are located in
         the United States.

</TABLE>

         The calculation of estimated future net cash flows in the following
         table assumed the continuation of existing economic conditions and
         applied year-end prices (except for future price changes as allowed by
         contract) of gas and condensate to the expected future production of
         such reserves, less estimated future expenditures (based on current
         costs) to be incurred in developing and producing those proved
         reserves.

         The standardized measure of discounted future net cash flows does not
         purport, nor should it be interpreted, to present the fair market
         value of a company's gas and oil reserves. These estimates reflect
         proved reserves only and ignore, among other things, changes in prices
         and costs, revenues that could result from probable reserves which
         could become proved reserves in fiscal 1998 or later years, and the
         risks inherent in reserve estimates.

L.P., a Delaware limited partnership, RIMCO PARTNERS, L.P. 11, a Delaware
limited partnership, RIMCO PARTNERS, L.P. 111, a Delaware limited partnership,
and RIMCO PARTNERS, L.P. IV, a Delaware limited partnership (collectively, the
"Noteholders").

     In consideration of the mutual covenants herein contained, the Company and
the Noteholders agree as follows:

                              DEFINITIONS, ETC.

     Section 1.01. Certain Defined Terms. Capitalized terms used in this
Agreement and not otherwise defined herein shall have the respective meanings
set forth in Annex A attached hereto (such meanings to be equally applicable to
both singular and plural forms of the terms defined).

     Section 1.02. Covenant Construction. Each covenant contained herein shall
be construed (absent express provision to the contrary) as being independent of
each other covenant contained herein, so that compliance with any one covenant
shall not (absent such an express contrary provision) be deemed to excuse
compliance with any other covenant. Where any provision herein refers to action
to be taken by any Person, or which such Person is prohibited from taking, such
provision shall be applicable whether such action is taken directly or
indirectly by such Person.

     Section 1.03. Other Rules of Construction. The words "hereof," "herein"
and "hereunder" and words of similar import when used in this Agreement shall
refer to this Agreement as a whole and not to any particular provision of this
Agreement. All references herein to articles, sections, annexes, exhibits and
schedules shall, unless the context requires a different construction, be
deemed to be references to the articles and sections of this Agreement and the
annexes, exhibits and schedules attached hereto and made a part hereof. In this
Agreement, unless a clear contrary intention appears, the word "including" (and
with correlative meaning "include") means including, without limiting the
generality of any description preceding such term. The headings of the various
articles and sections of this Agreement are for convenience only and shall not
affect the meaning of the terms and conditions of this Agreement.  No provision
of this Agreement shall be interpreted or construed against any party solely
because that party or its legal representative drafted such provision.

                                SALE OF NOTES

     Section 2.01. Notes. The Company will authorize the issue and sale of
$2,000,000 aggregate principal amount of its 12% Senior Secured General

Company, Notes in the principal amount specified opposite such Noteholder's
name in Schedule A at the purchase price of 100% of the principal amount

                                   CLOSING

tender such Notes to the Noteholders as provided above in this Article III, or
any of the conditions specified in Article IV shall not have been fulfilled to
the Noteholders' satisfaction, the Noteholders shall, at the Noteholders'
election, be relieved of all further obligations under this Agreement, without
thereby waiving any rights the Noteholders may have by reason of such failure
or such nonfulfillment.

                                  ARTICLE V
                REPRESENTATIONS AND WARRANTIES OF THE COMPANY

          The Company represents and warrants to the Noteholders that:

          Section 5.01. Organization; Power and Authority. The Company is a
corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware, and is duly qualified as a foreign corporation
and is in good standing in each jurisdiction in which such qualification is
required by law, other than those jurisdictions as to which the failure to be
so qualified or in good standing could not, individually or in the aggregate,
reasonably be expected to have a Material Adverse Effect. The Company has the
corporate power and authority to own or hold under lease the properties it
purports to own or hold under lease, to transact the business it transacts and
proposes to transact, to execute and deliver this Agreement mid the other
Transaction Documents and to perform the provisions hereof and thereof.

          Section 5.02. Authorization, etc. This Agreement and the other
Transaction Documents have been duly authorized by all necessary corporate
action on the part of the Company, and this Agreement constitutes, and upon
execution and delivery thereof each other Transaction Document will constitute,
a legal, valid and binding obligation of the Company enforceable against the
Company in accordance with its terms, except as such enforceability may be
limited by (a) applicable bankruptcy, insolvency, reorganization, moratorium or
other similar laws affecting the enforcement of creditors' rights generally and
(b) general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

          Section 5.03.  Compliance With Laws, Other Instruments, etc.  The
execution, delivery and performance by the Company of this Agreement and the
other Transaction Documents will not (a) contravene, result in any breach of, or
constitute a default under, or result in the creation of any Lien in respect
of any property of the Company or any Subsidiary under, any indenture, mortgage,
deed of trust, loan, purchase or credit agreement, lease, corporate charter or
by-laws, or any other agreement or instrument to which the Company or any
Subsidiary is bound or by which the Company or any Subsidiary or any of their
respective properties may be bound or affected, (b)



                                     -4-
<PAGE>   6
conflict with or result in a breach of any of the terms, conditions or
provisions of any order, judgment, decree, or ruling of any court, arbitrator
or Governmental Authority applicable to the Company or any Subsidiary or (c)
violate any provision of any statute or other rule or regulation of any
Governmental Authority applicable to the Company or any Subsidiary.

     SECTION 5.04. Governmental Authorizations, Etc. No consent, approval or
authorization of, or registration, filing or declaration with, any Governmental
Authority is required in connection with the execution, delivery or performance
by the Company of this Agreement or the other Transaction Documents.

     SECTION 5.05. Subsidiaries. Schedule 5.05 contains complete and correct
lists of the Company's Subsidiaries, showing, as to each Subsidiary, the
correct name thereof, the jurisdiction of its organization, and the percentage
of shares of each class of its capital stock or similar equity interests
outstanding owned by the Company and each other Subsidiary. No Subsidiary is a
party to, or otherwise subject to any legal restriction or any agreement (other
than this Agreement and customary limitations imposed by corporate law
statutes) restricting the ability of such Subsidiary to pay dividends out of
profits or make any other similar distributions of profits to the Company or
any of its Subsidiaries that owns outstanding shares of capital stock or
similar equity interests of such Subsidiary.

     SECTION 5.06. Financial Statements. The consolidated balance sheet of the
Company and its Subsidiaries as at June 30, 1996, and the related consolidated
statements of income, retained earnings and cash flows for the 12-month period
then ended, copies of which the Company has delivered to each Noteholder,
fairly present in all material respects the consolidated financial position of
the Company and its Subsidiaries as of such date and the consolidated results
of their operations and cash flows for such period and have been prepared in
accordance with GAAP consistently applied throughout the periods involved
except as set forth in the notes thereto.

     SECTION 5.07. Disclosure. This Agreement, the documents, certificates or
other writings delivered to the Noteholders by or on behalf of the Company in
connection with the transactions contemplated hereby, the financial statements
referred to in Section 5.06 and the Form 10-Qs filed by the Company with the
Securities Exchange Commission since June 30, 1996, taken as a whole, do not
contain any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein not misleading. Since June 30,
1996, except as otherwise disclosed in writing to the Noteholders there has
been no change in the financial condition, operations, business, properties or
prospects of the Company or any Subsidiary except changes that individually
or in the aggregate could not reasonably be expected to have a Material Adverse
Effect.  There is no fact known to the Company that could reasonably be
expected to have a Material Adverse Effect that has not been set forth herein
or in the other documents, certificates and other writings (including the
financial statements referred to in Section 5.06) delivered to the Noteholders
by or on behalf of the Company specifically for use in connection with the
transactions contemplated hereby.



                                     -5-
<PAGE>   7
     Section 5.08.  Litigation. Except as disclosed in Schedule 5.08, there are
no actions, suits or proceedings pending or, to the knowledge of the Company,
threatened against or affecting the Company or any Subsidiary or any property
of the Company or any Subsidiary in any court or before any arbitrator of any
kind or before or by any Governmental Authority that, individually or in the
aggregate, could reasonably be expected to have a Material Adverse Effect.

     Section 5.09.  Observance of Agreements, Statutes and Orders. Neither the
Company nor any Subsidiary is in default under any term of any agreement or
instrument to which it is a party or by which it is bound, or any order,
judgment, decree or ruling of any court, arbitrator or Governmental Authority
or is in violation of any applicable law, ordinance, rule or regulation
(including without limitation Environmental Laws) of any Governmental
Authority, which default or violation, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect.

     Section 5.10.  Taxes. The Company and its Subsidiaries have filed all tax
returns that are required to have been filed in any jurisdiction, and have paid
all taxes shown to be due and payable on such returns and all other taxes and
assessments levied upon them or their properties, assets, income or franchises,
to the extent such taxes and assessments have become due and payable and before
they have become delinquent, except for any taxes and assessments (i) the
amount of which is not individually or in the aggregate Material or (ii) the
amount, applicability or validity of which is currently being contested in good
faith by appropriate proceedings and with respect to which the Company or a
Subsidiary, as the case may be, has established adequate reserves in accordance
with GAAP. The Company knows of no basis for any other tax or assessment that,
if imposed, could reasonably be expected to have a Material Adverse Effect. The
charges, accruals and reserves on the books of the Company and its Subsidiaries
in respect of Federal, state or other taxes for all fiscal periods are adequate
in all material respects. The Federal income tax liabilities of the Company and
its Subsidiaries have been determined by the Internal Revenue Service and paid
for all fiscal years up to and including the fiscal year ended June 30, 1996.

     Section 5.11.  Title to Property. The Company and its Subsidiaries have
good and sufficient title to their respective properties that individually or
in the aggregate are Material, including all such properties reflected in the
most recent audited balance sheet referred to in Section 5.06 or purported to
have been acquired by the Company or any Subsidiary after said date, in each
case free and clear of Liens other than those permitted by this Agreement. All
leases that individually or in the aggregate are Material are valid and
subsisting and are in full force and effect in all material respects. 

     Section 5.12.  Licenses, Permits, etc. The Company and its subsidiaries own
or possess all licenses, permits, franchises, authorizations, patents,
copyrights, service marks, trademarks and trade names, or rights thereto, that
individually or in the aggregate are Material, without known conflict with
the rights of others. To the best knowledge of the Company, (a) no product of
the Company infringes in any material respect any license, permit, franchise,
authorization, patent, copyright, service mark, trademarks, trade name or other
right owned by any


                                      -6-
<PAGE>   8

other Person; and (b) there is no Material violation by any Person of any right
of the Company or any of its Subsidiaries with respect to any patent,
copyright, service mark, trademark, trade name or other right owned or used by
the Company or any of its Subsidiaries.

     Section 5.13.  Compliance with ERISA.

     (a)  The Company and each ERISA Affiliate have operated and administered
each Plan, if any, in compliance with all applicable laws except for such
instances of noncompliance as have not resulted in and could not reasonably be
expected to result in a Material Adverse Effect. Neither the Company nor any
ERISA Affiliate has incurred any liability pursuant to Title I or IV or ERISA
or the penalty or excise tax provisions of the Code relating to employee
benefit plans (as defined in Section 3 of ERISA), and no event, transaction or
condition has occurred or exists that could reasonably be expected to result in
the incurrence of any such liability by the Company or any ERISA Affiliate, or
in the imposition of any Lien on any of the rights, properties or assets of the
Company or any ERISA Affiliate, in either case pursuant to Title I or IV of
ERISA or to such penalty or excise tax provisions or to Section 401(a)(29) or
412 of the Code, other than such liabilities or Liens as would not be
individually or in the aggregate Material.

     (b)  The present value of the aggregate benefit liabilities under each of
the Plans (other than Multiemployer Plans), determined as of the end of such
Plan's most recently ended plan year on the basis of the actuarial assumptions
specified for funding purposes in such Plan's most recent actuarial valuation
report, did not exceed the aggregate current value of the assets of such Plan
allocable to such benefit liabilities. The term "benefit liabilities" has the
meaning specified in section 4001 of ERISA and the terms "current value" and
"present value" have the meaning specified in section 3 of ERISA.

     (c)  The Company and its ERISA Affiliates have not incurred withdrawal
liabilities (and are not subject to contingent withdrawal liabilities) under
section 4201 or 4204 of ERISA in respect of Multiemployer Plans that
individually or in the aggregate are Material.

     (d)  The expected post-retirement benefit obligation (determined as of the
last day of the Company's most recently ended fiscal year in accordance with
Financial Accounting Standards Board Statement No. 106, without regard to
liabilities attributable to continuation coverage mandated by section 4980B of
the Code) of the Company and its Subsidiaries is not Material.

     Section 5.14.  Use of Proceeds; Margin Regulations. The Company will apply
the proceeds of the sale of the Notes to pay for the settlement of that certain
lawsuit styled The Universal Seismac Associates, Inc. Stockholders' Protective
Committee, Michael T. Kanarellis, and Robert J. Kecseg vs. Michael J. Pawelek,
Ronald L. England, Calvin G. Cobb, Gary Milavec, Steven Oakes, Rick Trapp,
Universal Seismic Associates, Inc., RIMCO Associates, Inc.; and Resource 
Investors Management Co., L.P.; CA No. 97-22 (RRM) in the United States District
Court of the District of Delaware and for legal fees and accounting fees related
thereto. No part of the proceeds from the sale

                                      -7-
<PAGE>   9

of the Notes hereunder will be used, directly or indirectly, for the purpose of
buying or carrying any margin stock within the meaning of Regulation G of the
Board of Governors of the Federal Reserve System (12 CFR 207), or for the
purpose of buying or carrying or trading in any securities under such
circumstances as to involve the Company in a violation of Regulation X of said
Board (12 CFR 224) or to involve any broker or dealer in a violation of
Regulation T of said Board (12 CFR 220).

     Section 5.15.  Status under Certain Statutes. Neither the Company nor any
Subsidiary is subject to regulation under the Investment Company Act of 1940,
as amended, the Public Utility Holding Company Act of 1935, as amended, the
Interstate Commerce Act, as amended, or the Federal Power Act, as amended.

     Section 5.16.  Capitalization. The authorized capital stock of the Company
consists solely of 20,000,000 shares of $.0001 par common stock, of which
5,234,109 shares are issued and outstanding.

     Section 5.17.  Securities Matters. Other than offers to Accredited
Investors, neither the Company nor anyone acting on its behalf has directly or
indirectly offered the Notes or any part thereof or any similar securities for
sale to, or solicited any offer to buy any of the same from, or otherwise
approached or negotiated in respect thereof with, anyone other than the
Noteholders named in Schedule A. Neither the Company nor anyone acting on its
behalf has taken or will take any action which would subject the issuance and
sale of the Notes to the registration and prospectus delivery provisions of the
Securities Act.

     Section 5.18.  Environmental Matters. Neither the Company nor any
Subsidiary has knowledge of any claim or has received any notice of any claim,
and no proceeding has been instituted raising any claim against the Company or
any of its Subsidiaries or any of their respective real properties now or
formerly owned, leased or operated by any of them or other assets, alleging any
damage to the environment or violation of any Environmental Laws, except, in
each case, such as could not reasonably be expected to result in a Material
Adverse Effect. Except as otherwise disclosed to the Noteholders in writing,
(a) neither the Company nor any Subsidiary has knowledge of any facts which
would give rise to any claim, public or private, of violation of Environmental
Laws or damage to the environment emanating from, occurring on or in any way
related to real properties now or formerly owned, leased or operated by any of
them or to other assets or their use, except, in each case, such as could not
reasonably be expected to result in a Material Adverse Effect; (b) neither the
Company nor any of its Subsidiaries has stored any Hazardous Materials on real
properties now or formerly owned, leased or operated by any of them and has not
disposed of any Hazardous Materials in a manner contrary to any Environmental
Laws in each case in any manner that could reasonably be expected to result in
a Material Adverse Effect; and (c) all buildings on all real properties now
owned, leased or operated by the Company or any of its Subsidiaries are in
compliance with applicable Environmental Laws, except where failure to comply
could not reasonably be expected to result in a Material Adverse Effect.

without limitation, Environmental Laws, and will obtain and maintain in effect
all licenses, certificates, permits, franchises and other governmental
authorizations necessary to the ownership of their respective properties or to
the conduct of their respective businesses, in each case to the extent
necessary to ensure that non-compliance with such laws, ordinances or
governmental rules or regulations or failures to obtain or maintain in effect
such licenses, certificates, permits, franchises and other governmental
authorizations could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect. The Company will, and will cause
each of its Subsidiaries to, comply with, and perform their respective
obligations under, each contract or agreement to which each is a party, unless,
in the good faith judgment of the Company, the failure to so comply or perform
could not reasonably be expected to have a Material Adverse Effect.

Subsidiaries to, maintain, with financially sound and reputable insurers,
insurance with respect to their respective properties and businesses against
such casualties and contingencies, of such types, on such terms and in such
amounts (including deductibles, co-insurance and self-insurance, if adequate

connection therewith may be properly conducted at all times, provided that this
Section shall not prevent the Company or any Subsidiary from discontinuing the
operation and the maintenance of any of its properties if such discontinuance
is desirable in the conduct of its business and the Company has concluded that
such discontinuance could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

     Section 9.04. Payment of Taxes and Claims. The Company will, and will
cause each of its Subsidiaries to, file all tax returns required to be filed in
any jurisdiction and to pay and discharge all taxes shown to be due and

assets, income or franchises, to the extent such taxes and assessments have
become due and payable and before they have become delinquent and all claims
for which sums have become due and payable that have or might become a Lien on
properties or assets of the Company or any Subsidiary, provided that neither
the Company nor any Subsidiary need pay any such tax or assessment or claims if
(i) the amount, applicability or validity thereof is contested by the Company
or such Subsidiary on a timely basis in good faith and in appropriate
proceedings, and the Company or a Subsidiary has established adequate reserves
therefor in accordance with GAAP on the books of the Company or such Subsidiary
or (ii) the nonpayment of all such taxes and assessments in the aggregate could
not reasonably be expected to have a Material Adverse Effect.

     Section 9.05. Corporate Existence, etc. The Company will at all times
preserve and keep in full force and effect its corporate existence. The Company
will at all times preserve and keep in full force and effect the corporate
existence of each of its Subsidiaries and all rights and franchises of the
Company and its Subsidiaries unless, in the good faith judgment of the Company,
the termination of or failure to preserve and keep in full force and effect
such corporate existence, right or franchise could not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect.

cancellation thereof, the Company at its own expense shall execute and deliver,
in lieu thereof, a new Note, dated and bearing interest from the date to which
interest shall have been paid on such lost, stolen, destroyed or mutilated Note

be waived (either retroactively or prospectively), with (and only with) the
written consent of the Company and the Required Holders, except that (a) no
amendment or waiver of any of the provisions of Articles II, III, IV or V, or
any defined term (as it is used therein), will be effective as to the
Noteholders unless consented to by all of the Noteholders in writing, and (b)
no such amendment or waiver may, without the written consent of the holder of
each Note at the time outstanding affected thereby, (i) subject to the

of Default not expressly amended or waived or impair any right consequent
thereon. No course of dealing between the Company and the holder of any Note
nor any delay in exercising any rights hereunder or under any Note shall
operate as a waiver of any rights of any holder of such Note.

               Section 13.04. Notices. All notices and communications provided
for hereunder shall be in writing and sent (a) by telecopy if the sender on the
same day sends a confirming copy of such notice by a recognized overnight
delivery service (charges prepaid), or (b) by registered or certified mail with
return receipt requested (postage prepaid), or (c) by a recognized overnight
delivery service (with charges prepaid). Any such notice must be sent (i) if
to a Noteholder, to its address specified for such communications in Schedule
A, or at such other address as it shall have specified to the Company in
writing, (ii) if to the Company, to the Company at 16420 Park Ten Place, Suite
300, Houston, Texas 77084, Telecopy No.: 281-578-7091, or at such other address
as the Company shall have specified to the holder of each Note in writing.
Notices under this Section 13.04 will be deemed given only when actually
received.

              Section 13.05. Limitation on Interest. Each provision in this
Agreement and each other Transaction Document is expressly limited so that in
no event whatsoever shall the amount paid, or otherwise agreed to be paid, by
the Company for the use, forbearance or detention of the money to be loaned
under this Agreement or any other Transaction Document or otherwise (including
any sums paid as required by any covenant or obligation contained herein or in
any other Transaction Document which is for the use, forbearance or detention
of such money), exceed that amount of money which would cause the effective rate
of interest thereon to exceed the Highest Lawful Rate, and all amounts owed
under this agreement and each other Transaction Document shall be held to be
subject to reduction to the effect that such amounts so paid or agreed to be
paid which are for the use, forbearance or detention of money under this
Agreement or such Transaction


                                     -22-
<PAGE>   24
Document shall in no event exceed that amount of money which would cause the
effective rate of interest thereon to exceed the Highest Lawful Rate.
Notwithstanding the provisions of Section 13.14, to the extent that the Highest
Lawful Rate applicable to a Noteholder is at any time determined by Texas law,
such rate shall be the "indicated rate ceiling" described in Section (a)(1) of
Article 1.04 of Chapter 1, Title 79, of the Revised Civil Statutes of Texas,
1925, as amended; provided, however, to the extent permitted by such Article,
the Noteholders from time to time by notice to Company may revise the aforesaid
election of such interest rate ceiling as such ceiling affects the then-current
or future balances of the loans outstanding under the Notes. Notwithstanding
any provision in this Agreement or any other Transaction Document to the
contrary, if the maturity of the Notes or the obligations in respect of the
other Transaction Documents are accelerated for any reason, or in the event of
prepayment of all or any portion of the Notes or the obligations in respect of
the other Transaction Documents by the Company or in any other event, earned
interest on the Notes and such other obligations of the Company may never
exceed the maximum amount permitted by applicable law, and any unearned
interest otherwise payable under the Notes or the obligations in respect of the
other Transaction Documents that is in excess of the maximum amount permitted
by applicable law shall be canceled automatically as of the date of such
acceleration or prepayment or other such event and, if theretofore paid, shall
be credited on the principal of the Notes or, if the principal of the Notes has
been paid in full, refunded to the Company. In determining whether or not the
interest paid or payable, under any specific contingency, exceeds the Highest
Lawful Rate, the Company and the Noteholders shall, to the maximum extent
permitted by applicable law, amortize, prorate, allocate and spread, in equal
parts during the period of the actual term of this Agreement, all interest at
any time contracted for, charged, received or reserved in connection with the
Transaction Documents.

              Section 13.06. Indemnification. The Company agrees to indemnify,
defend and hold each Noteholder, their partners and their respective officers,
employees, agents, directors, partners, affiliates and shareholders
(collectively, "Indemnified Persons") harmless from and against any and all
loss, liability, damage, judgment, claim, deficiency or reasonable expense
(including interest, penalties, reasonable attorneys' fees and amounts paid in
settlement) incurred by or asserted against any Indemnified Person arising out

by the parties hereto and thereto of their respective obligations hereunder and
thereunder and consummation of the transactions contemplated hereby and
thereby, (b) the actual or proposed use of the proceeds of the loans
contemplated hereby, (c) any violation by the Company or any of its
Subsidiaries of any requirement of law, including but not limited to
Environmental Laws, (d) any Noteholder being deemed an operator of any real or
personal property of the Company in circumstances in which no Noteholder is
generally operating or generally exercising control over such property, to the
extent such losses, liabilities, damages, judgments, claims, deficiencies or
expenses arise out of or result from any Hazardous Materials located in, on or
under such property or (e) any claim, litigation, investigation or proceeding
relating to any of the foregoing, whether or not any Indemnified Person is a
party thereto; provided that such indemnity shall not apply to any such losses,
claims, damages, liabilities or related expenses that result from the gross
negligence or willful misconduct of, or willful violation of the Transaction
Documents by,

Person will attempt to consult with the Company prior to entering into any
settlement of any lawsuit or proceeding that could give rise to a claim for
indemnity under this Section 13.06, although nothing herein shall give the
Company the right to direct, or control any such settlement negotiations or
any related lawsuit or proceeding on behalf of such Indemnified Party. The

that is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof, and any
such prohibition or unenforceability in any jurisdiction shall (to the full
extent permitted by law) not invalidate or render unenforceable such provision
in any other jurisdiction.

               Section 13.09. Counterparts. This Agreement may be executed in
any number of counterparts, each of which shall be an original but all of which

       of Wise County, Texas ("Shamrock Pipe").

that one or more of the defendants caused the plaintiffs' pipe to rupture as a
result of negligent conduct of seismic testing, resulting in down time and lost
gasoline. Presently USA's insurance company has assumed the defense and has
hired counsel to represent it in the case. MAS is a wholly-owned subsidiary of
USA which was formed for the purpose of acquiring the assets, including the
tradename, of a now dissolved corporation. The asset acquisition occurred after
the alleged incident giving rise to this suit. Accordingly. plaintiff's counsel
believes that the former owner of the corporate name Marine Automated Surveys,
now known as JBX Corporation, will be joined and that all claims with respect
to MAS will be dismissed.

relevant to the Company.

applicable to other senior executive employees of the Company. Nothing herein,
however, shall be construed as limiting the right of the Employee to additional

for the immediately preceding year pursuant to Section 4(b). The Employer and

the Company's business and affairs without the concerns that normally arise

Employee's employment on account of his death or Retirement (as hereafter
defined) will not be considered a termination of the Employee's employment by
the Company and will not require the Company to pay and provide any severance

to the company; provided that no act, or failure to act, on the Employee's part
shall be considered "willful" unless done, or omitted to be done, in bad faith

opposed to, the best interests of the company, or (iii) for a serious conduct
violation specifically listed in Article IV., Conduct, page 9, of the Universal
Seismic Associates, Inc. Employee Handbook in effect on January 1, 1995. It is

                              EMPLOYMENT AGREEMENT


     This Employment Agreement executed by and between Universal Seismic
Associates, Inc., a Delaware corporation ("Company") and Patrick A. Donais now
residing in Spring, Texas ("Employee").


                              W I T N E S S E T H

WHEREAS, the Employee is employed by the  Company  in  a  managerial  or
executive capacity and desires to continue such employment; and

WHEREAS, the Company desires to retain the services of Employee in such
capacity.

NOW, THEREFORE, in consideration of the covenants and agreements herein
contained, the parties hereto agree as follows:

     1.  The Company agrees to employ the Employee, and the Employee agrees to
render Employee's exclusive and full time service to the Company upon the terms
and conditions set forth in this Agreement. Such employment shall be initially
as Vice President, Exploration and Production, of the UNEXCO subsidiary of the
Company and with such duties as assigned from time to time by the Company. Such
employment shall commence on August 1, 1997 and shall continue through July 31,
1998, and shall extend and renew automatically for successive one (1) year
terms unless the Employee or the Company shall terminate such employment by
written notice of termination given to the other party at least 60 days prior
to the expiration of the one (1) year term then in effect. Termination by
either party, in accordance with the provisions of the preceding sentence,
shall not require a statement of the reason or cause for such termination and
shall not be deemed a breach or violation of the Agreement by the party giving
such notice. As used in this Agreement, the phrase "term of this Agreement"
shall be deemed to include the period subsequent to the date hereof and prior
to termination of this Agreement; provided, however, such phrase shall not be
construed as limiting the enforceability by either party of any rights which
survive termination of this Agreement.

     2.  In consideration of the services and duties to be rendered and
performed by the Employee during the term of this Agreement, including the
assumption of the duties and responsibilities as a manager or executive of the
Company, its affiliates and/or subsidiaries, the Company agrees to pay and
provide for the Employee the compensation and benefits described below:

     (a) An annual salary, payable in the amount of not less than $3,846.15
every two (2) weeks, or in such greater amount as may from time to time be
fixed by the Board of Directors of the Company.


<PAGE>   2
     (b) An automobile which is reasonable and customary for the position held
by Employee in a company of the size and nature of the Company, which the
Company shall insure, maintain, service and fuel. In lieu of providing such
automobile, the Company may, at its sole option and discretion, pay Employee an
automobile allowance in accordance with the Company's policies for such
allowances.

     (c) All payments and/or benefits under any pensions, profit-sharing,
thrift, bonus, incentive, stock option or stock appreciation or other employee
benefit plan, including any life insurance, accident, medical, disability,
health or relocation plan or policy (all of which are included by reference to
the term "Plan") maintained by the Company for its employees, generally.
Nothing herein, however, shall be construed as limiting the right of the
Employee to additional or other and greater benefits if the provisions of this
Agreement obligate the Company to provide such other or greater benefits.

     (d) Company shall provide directors and officers liability insurance
coverages of the Employee as an officer and director of the Company and of any
of its subsidiaries or affiliates, and Company shall provide indemnification of
the Employee as an officer and director of the Company as permitted by
applicable law and the applicable provisions of the Company's Articles of
Incorporation and By-laws, as amended from time to time.

     (e) Any and all of Employee's service as an employee, officer or director
of any subsidiary or other affiliate of the Company shall be performed without
additional compensation.

     3.  Employee's location of employment will be at Houston, Texas and/or at
such other locations as may be designated from time to time by the Company;
provided, however, in the event Employee while employed outside Texas is
terminated without good cause or due to a general reduction in force by
Employer or the expiration of this Agreement, Employer will pay the reasonable
and necessary cost of travel (economy class or equivalent) and transportation
of household goods and furnishings (excluding vehicles and boats) of the
Employee, his spouse and dependent children from the location where employed at
the time of such termination or expiration to Spring, Texas.

     4.  The Employee shall be reimbursed for out-of-pocket expenses reasonably
incurred from time to time on behalf of the Company or any subsidiary or in the
performance of his duties under this Agreement, upon the presentation of such
supporting documents and forms as required by the policies and procedures of
the Company.



                                       2

     5.  In the event Employee receives any advance payment or "draw" on any
compensation, expense, benefit, bonus or commission, or receives payment for or
charges to Company any improper expense or other improper payment or charge,
such payment, draw or charge shall be repaid by Employee on demand of Company
or, at Company's sole discretion and option, be off set at any time against any
salary, bonus, commission or any other payment owed by company to Employee.

     6.  Employee shall not, during the period of employment herein provided,
directly or indirectly invest or engage in any business which is competitive
with that of the Company or accept employment with or render services to a
competitor as a director, officer, agent, employee or consultant, or take any
action inconsistent with the fiduciary or other relationship of an employee to
an employer.

     7.  In the event that the employment of Employee hereunder shall be
terminated by the Company for cause, Employee agrees that during the period of
twelve (12) months following the termination of such employment Employee will
not, directly or indirectly, either through any kind of ownership (other than
ownership of securities of publicly held corporations of which Employee owns
less than one percent (1%) of any class of outstanding securities) or as a
director, officer, agent, employee or consultant, engage in any business within
the State of Texas which is competitive with the Company or its subsidiaries or
affiliates at the time such employment is terminated. Employee agrees the
foregoing covenant not to compete will also extend for a period of twelve (12)
months following termination of Employee's employment by the Company without
cause or by the Employee for other than cause if the Company elects, at its
sole option and discretion, at the time of such termination to so extend such
covenant and continues to pay Employee his salary in accordance with Section
2(a) during the time such covenant is in force. During employment and for
twelve (12) months following termination for any reason, Employee shall not
solicit any employee, agent or representative of the Company to terminate or
breach any employment, contract or any other relationship or duty to or with
the Company. It is expressly agreed that the remedy at law for breach of this
covenant is inadequate and that injunctive relief shall be available to prevent
the breach thereof. Employee hereby acknowledges and agrees that the
limitations as to time, geographical area, and scope of activity to be
restrained are reasonable and do not impose a greater restraint than is
necessary to protect the goodwill or other business interest of Company.

     8.  All information relating to the identity of the customers and suppliers
of the Company or its subsidiaries or affiliates, their arrangements with such
suppliers and customers, pricing methods and policies, technical, scientific
and financial information, data, designs, processes, procedures, formulas and
improvements relating to Company's or its subsidiary or affiliates 



                                       3
<PAGE>   4
products and services (hereinafter "Confidential Information"), shall be
treated as confidential by Employee both during and after the termination of
Employee's employment under this Agreement. Employee understands and
acknowledges that the Confidential Information, including without limitation
customer lists, accounts and information, are valuable, special and unique
assets and trade secrets of the Company and that the Company has taken measures
to prevent Confidential Information from becoming available to persons other
than those selected by the Company to have access to such Confidential
Information for limited purposes. Employee further acknowledges that prior to
Employee's employment by Company Employee had no knowledge of any of the
Confidential Information. Except with the prior approval of the Company,
Employee shall not disclose any of such Confidential Information at any time to
any person except personnel of the Company or its subsidiary or affiliated
corporations authorized by the Company to receive such Confidential
Information. In the event of a breach or threatened breach by the Employee of
the provisions of this paragraph, the Company shall, in addition to any other
available remedies, be entitled to any injunction restraining Employee from
disclosing, in whole or in part, any such information or from rendering any
services to any person, firm or corporation to whom any of such Confidential
Information may be disclosed or is threatened to be disclosed.

     9. All data, designs, processes, procedures, formulas, improvements,
drawings, software, photographs, copies and other records and written material
prepared, compiled or conceived by Employee, solely or jointly, during the
course of or in connection with Employee's duties with the Company, or with the
use of the time or materials of the Company, or which relates to the business
of the Company, or furnished to Employee while in the employ of the Company
shall be the sole and exclusive property of the Company, none of such, data,
designs, processes, procedures, formulas, improvements, drawings, software or
other records, or copies thereof shall be retained by Employee upon termination
of Employee's employment and shall be returned to the Company upon such
termination or at such other time the Company requests such return.

     10. Employee shall promptly disclose to the Company any and all
inventions, designs, improvements, and discoveries which Employee may now or
hereafter have, whether developed or conceived by Employee alone or with
others. All inventions, designs, improvements and discoveries which Employee,
alone or with others, develops or conceives during working hours, or with the
use of the Company property or assets, or which pertain or are related to the
business of the Company shall be the exclusive property of the Company.
Employee shall assist the Company to obtain patent, trademark, copyrights or
other rights, including executing documents necessary to vest full title
thereto in Company, and to protect such rights against infringement or
unauthorized disclosure.

continue to be binding upon Employee in accordance with their terms,
notwithstanding termination of Employee's employment hereunder for any reason;

                      EMPLOYMENT AGREEMENT


     This EMPLOYMENT AGREEMENT (this "Agreement") is made and entered into as

hereunder:

     4.1 Salary. During the Term, the Company shall pay Executive a monthly
base salary ("Base Salary") of $17,500, payable in advance on the first of each

     4.3 Participation in Benefit Plans. Except as provided below, during the
Term Executive shall be eligible to participate in all employee benefit plans
and arrangements now in effect or which may hereafter be established that are

executives of the Company. Notwithstanding the foregoing, Executive shall not
participate in any group health plan of the Company and, to the extent
Executive is eligible to participate therein by the terms of such plan,
Executive hereby waives such eligibility and participation.

     4.4 Reimbursement of Expenses. The Company shall reimburse Executive for

SECTION 5.   Termination.

     5.1 Termination by the Company Without Cause. The Company may terminate
Executive's employment other than for Cause or Executive becoming Disabled (as
such terms are defined below) at any time during the Term if the Board
determines, in its sole discretion, that the continued employment of Executive
is not in the continued interests of the Company. In the event the Company
terminates Executive's employment pursuant to this Section 5. 1, then Executive
shall

                                2


<PAGE>   3


be paid on termination (i) any unpaid Base Salary earned hereunder prior to the
termination date (the "Earned Amount"), and (ii) an amount equal to the amount
of Base Salary that Executive would receive if Executive's employment had
continued without change through the remainder of the original Term.

     5.2 Termination by the Company for Cause. The Company may terminate this
Agreement at any time, in the discretion of the Board, in the event of "Cause",
which shall mean (i) any conviction of Executive for a felony, (ii) any
material breach of any material provision of this Agreement by Executive, (iii)
any willful conduct by Executive materially injurious to the Company, (iv) any
willful failure by Executive to comply with any material policies, procedures,
or directives of the Audit Committee of the Board that are consistent with the
terms of this Agreement, (v) any fraud, misappropriation of funds,
embezzlement, or other similar acts of misconduct by Executive with respect to
the Company, or (vi) the failure by Executive to sign the Company's management
representation letter to the Company's auditors or the Company's Form 10-K, in
a form reasonably satisfactory to the Audit Committee; provided, however, Cause
shall exist with respect to a matter described in (ii), (iii) or (iv) above
that is capable of being corrected only if Executive shall first be given
notice from the Audit Committee of such failure and such failure shall not have
been cured within five days after such notice or, if such failure is not
capable of being cured within five days, Executive shall not have commenced and
be diligently pursuing in good faith efforts to cure such default. In the event
the Company terminates Executive's employment pursuant to this Section 5.2 for
Cause, then Executive shall be paid on termination the Earned Amount and the
Company shall have no further liability or obligations to Executive pursuant to
this Agreement.

     5.3 Termination Upon Death or Disability of Executive. This Agreement shall
terminate upon the death of Executive or upon Executive becoming Disabled (as
defined below). In the event of a termination of this Agreement pursuant to
this Section 5.3, Executive (or Executive's estate, if applicable) shall be
paid on termination the Earned Amount and the Company shall have no further
liability or obligations to Executive pursuant to this Agreement. For purposes
of this Agreement, "Disabled" shall mean that Executive shall have incurred a
mental or physical disability that has prevented Executive from substantially
performing his duties under this Agreement for a period of 30 days within any 45
day period.

     5.4 Voluntary Resignation for Good Reason. Executive may resign
Executive's employment with the Company at any time and, if such resignation is
for "Good Reason" (as defined below), Executive shall be entitled to the same
payments that Executive would receive under Section 5.1 if Executive's
employment were being terminated by the Company other than for Cause or
Executive becoming Disabled. "Good Reason" shall mean: (i) the failure by the
Company to pay when due any portion of the Base Salary payable to Executive
hereunder, (ii) any material breach by the Company of any material provision of
this Agreement, (iii) the Company's failure at any time to cause Executive to
be covered as an insured under a policy or contract that insures directors and
officers of the Company against personal liability for acts or omissions or
alleged acts or omissions in connection with such individual's service as an
officer or director of the Company or service in other capacities at the
request of the Company ("D&O Policy") on terms and conditions that are
substantially the same as the coverages provided to officers and directors of
the Company as of the date of this Agreement, (iv) the failure of the Company
to provide Executive a written binding

                                       3


<PAGE>   4


commitment by September 17, 1997 that the Company will maintain coverage for 
Executive under the Company's D&O Policy for a period of three years
following the Term of this Agreement for claims arising from acts or omissions
or alleged acts or omission occurring during the Term of this Agreement, or (v)
the failure of Resource Investors Management Company Limited Partnership (or
its affiliates) to provide the Company with a written binding commitment by
September 17, 1997 to finance the costs of such coverage referred to in clause
(iv) immediately above; provided, however, Good Reason shall exist with respect
to a matter that is capable of being corrected by the Company only if such
matter is not corrected by the Company within a reasonable period, not to
exceed 30 days, following its receipt of written notice of such matter from
Executive, and in no event shall a termination by Executive occurring more
than 35 days following any such written notice of the event described above be
for Good Reason.

SECTION 6.   Covenant Not to Compete; Confidentiality.

     6.1 Noncompetition. Unless granted written permission by the Board, while
employed by the Company and for a period of 12 months after the termination of
such employment, Executive covenants that Executive shall not (i) own (as a
proprietor, partner, or stockholder of greater than one percent of outstanding
equity securities, interests or otherwise) an interest in, or (ii) participate
(as an officer, director, or in any other capacity) in the management,
operation, or control of, or (iii) perform services as or act in the capacity
of any employee, independent contractor, consultant, or agent of any business
which engages in activities that are competitive with the three-dimensional
seismic acquisition and processing services of the Company or its subsidiaries
in an area within North America in which the Company is then conducting
business and in which the Company commenced conducting such business prior to
the commencement of such activities therein by Executive.

     6.2 Confidentiality. Executive acknowledges that in the course of
Executive's employment by the Company, Executive will be furnished and have
access to certain information concerning the business, financial condition,
operations, assets and liabilities of the Company that is confidential or
proprietary in nature. All such information (irrespective of the form of
communication) is hereinafter collectively referred to as the "Information."
Executive agrees to keep the Information confidential and agrees that Executive
will use the Information solely for the purpose of performing Executive's
duties hereunder or as otherwise authorized by the Board. This Agreement shall
be inoperative as to such portions of the Information which (a) are or become
generally available to the public other than as a result of a disclosure by
Executive in violation of this Agreement, (b) become available to Executive on
a non-confidential basis from a source other than the Company that is not bound
by an obligation of confidentiality to such entity or entities, or (c) are
required to be disclosed by an order or decree of a court or other tribunal of
competent jurisdiction, provided the Company is given prompt notice of, and the
opportunity to contest disclosure under, such order or decree. Upon termination
of this Agreement, Executive will return all Information furnished by the
Company and any documents that contain, reflect, or are based upon, in whole or
in part, the Information.

     6.3 Equitable Relief. Executive acknowledges and agrees that it would be
difficult to measure damage to the Company from any breach by Executive of
Section 6.1 or 6.2 and that

                                       4


<PAGE>   5


monetary damages would be an inadequate remedy for any such breach.
Accordingly, Executive agrees that if Executive shall breach Section 6.1 or
6.2, the Company shall be entitled, in addition to all other remedies it may
have at law or in equity, to an injunction or other appropriate orders or
equitable relief to restrain any such breach, without showing or proving any
actual damage sustained by the Company.

     6.4 Executive's Acknowledgment. Executive hereby expressly acknowledges and
agrees that (i) the restrictions and obligations set forth in and imposed by
this Section 6 will not prevent Executive from obtaining gainful employment in
Executive's field of expertise or cause Executive undue hardship, and (ii) in
view and consideration of the substantial benefits Executive will receive from
the Company pursuant to this Agreement, the restrictions and obligations
imposed on Executive under this Section 6 are reasonable and necessary to
protect the legitimate business interests of the Company.


Section 7.   Indemnification.

     (a) During the Term, the Company shall cause Executive to be covered by
and named as an insured under any policy or contract of insurance obtained by
it to insure its directors and officers against personal liability for acts or
omissions in connection with service as an officer or director of the Company
or service in other capacities at the request of the Company. The coverage
provided to Executive pursuant to this Section 7 shall be of a scope and on
terms and conditions at least as favorable as the coverage (if any) provided to
any other officer or director of the Company.

     (b) To the maximum extent permitted under applicable law, the Company
shall indemnify Executive against and hold Executive harmless from any costs,
liabilities, losses and exposures ("Liabilities") for an act or omission or
alleged act or omission of Executive as an officer or employee, of the Company.
In addition, to the maximum extent permitted by applicable law, the Company
shall advance to Executive all reasonable fees and expenses Executive may incur
in connection with any such Liability; provided, however, that Executive shall
be required to reimburse the Company for all sums advanced to Executive to the
extent it is determined such advanced amounts may not be properly paid by the
Company.

SECTION 8.   Representations and Warranties.

     8.1 By the Executive. Executive represents and warrants to the Company
that (i) Executive is under no contractual or other restriction or obligation
which would prevent the performance of Executive's duties hereunder or
interfere with the rights of the Company hereunder and (ii) this Agreement has

                    To Purchase Shares of Common Stock of

     THIS CERTIFIES THAT, for value received, RONALD L. ENGLAND, whose address

Period"), 5,000 fully paid and nonassessable shares of the Company's common
stock, $0.0001 par value (the "Common Stock"), at the price of $2.50 per Share
("Share Purchase Price"); subject, however, to the provisions and upon the
terms and conditions herinafter set forth in this Warrant ("Warrant"). The 
shares of Common Stock deliverable upon exercise of this Warrant shall be 
referred to hereinafter collectively as the "Shares."

     1. Exercise: Issuance of Certificates: Payment for Shares. The rights
represented by this Warrant may be exercised by the Holder, in whole or in
part, at any time or from time to time during the Exercise Period, upon
presentation and surrender of This Warrant to the Company, at its principal
office as set forth above, or at such other place as the Company may designate
written notice from the Holder stating that the Holder is exercising this
Warrant and specifying the number of Shares that the Holder desires to purchase
(the "Notice") and accompanied by payment of the applicable Share Purchase
Price for each Share so purchased and all federal and state taxes or other
governmental charge applicable to such exercise and issuance of the Shares.
Such payment shall be made, in cash or by certified, bank or cashier's check,

Holder has complied with the provisions of this Section 1.

     2. Restrictions on Exercise or Transfer of Warrant. The Holder may not
sell, assign, transfer or hypothecate this Warrant or any interest herein
except as set forth in the last sentence of this Section, and any attempt by
the Holder to do so shall be void. Neither this Warrant nor any interest herein
may be sold, assigned, transferred or hypothecated involuntarily or by
operation of law. The Company specifically understands and agrees that the
Warrant shall be fully transferable to any corporation of which the Holder is a
director or affiliate and has a 10% or more equity interest therein, provided
that the transferee specifically agrees to comply with the foregoing and the
Holder has a bona fide interest in such corporation and such transfer has not
been made to such corporation for the primary purpose of avoiding the foregoing
transfer restrictions.

     3. Reservation of Shares. The Company hereby agrees that at all times
during the Exercise Period there shall be reserved for issuance and delivery
upon exercise of this Warrant such number of Shares as shall be required for
issuance and delivery on exercise of this Warrant.

presentation, surrender, and cancellation of this Warrant. The Holder shall pay
all federal and state taxes or other governmental charge applicable to any
issuance of new Warrants under this Section 4.

     5. Rights of the Holder. The Holder shall not, by virtue of this Warrant,
be entitled to any rights of a shareholder in the Company, either at law or
equity. The rights of the Holder are limited to those expressed in the Warrant
and are not enforceable against the Company except to the extent set forth
herein.

     6. Adjustment and Other Events.

               (a) Definition. As used in this Section 6, "Stock" shall mean
shares of the Company's capital stock of any class, whether now or hereafter
authorized, that has the right to participate in the distribution of earnings
and assets of the Company without limit as to amount or percentage. As of the
date hereof, Stock consists of 20,000,000 authorized shares of the Company's
common stock, $0.0001 par value per share.

               (b) Stock Dividend or Distribution. If the Company shall declare
any dividend or other distribution upon its outstanding Stock payable in Stock,
or shall subdivide its outstanding shares of Stock into a greater number of
shares, then, on the effective date of such dividend, distribution or
subdivision, the number of Shares that may thereafter be purchased


                                     - 2 -


<PAGE>   3


upon the exercise of the rights represented hereby shall be increased in
proportion to the increase through such dividend, distribution or subdivision,
and the Share Purchase Price shall be decreased in such proportion. In case the
Company shall at any time combine the outstanding shares of its Stock into a
smaller number of shares, then, on the effective date of such combination, the
number of Shares that may thereafter be purchased upon the exercise of the
rights represented hereby shall be decreased in proportion to the decrease
through such combination, and the Share Purchase Price shall be increased in
such proportion.

               (c) Notice of Adjustment and-Other Events. The Company shall
give the Holder notice of any event requiring an adjustment as provided in
Subsection 6(b) at least ten days prior to the effective date of such event;
provided, however, that failure to give such notice shall not in any way
invalidate or otherwise limit or affect the validity or effectiveness of such
event.

               (d) Fractional Shares. No fractional shares of Common Stock or
scrip representing fractional shares of Common Stock shall be issued upon the
exercise of this Warrant, and the Company shall have no obligation to make any
cash payment with respect thereto.

               (e) Company-Held Stock. The number of shares of Stock of any
class at any time outstanding shall include all shares of Stock of that class
then owned or held by or for the account of the Company.

     7. Registration Rights.

               (a) Registrable Stock. As used in this Section 7, the term
"Registrable Stock" shall mean all Shares issued pursuant to the provisions of
this Warrant, but shall not include the Warrant.

               (b) Incidental Registration. In the event that the Company
proposes, at any time during the Exercise Period, to file a registration
statement on a general form of registration under the Securities Act of 1933,
as amended (the "Securities Act"), and relating to shares of Common Stock
issued or to be issued by it (other than a registration effected solely to
implement an employee benefit plan or solely with respect to a transaction to
which Rule 145 under the Securities Act is applicable), then it shall give
written notice of such proposal to all holders of Registrable Stock and any
other holders of securities of the Company having any rights to include
securities in such registration. Upon the written request of a holder or
holders of any shares of Registrable Stock given within ten days after receipt
of any such notice (stating the number of shares of Registrable Stock to be
disposed of and the intended method of disposition of such shares by such
holder or holders), the Company will use its best efforts to promptly cause all
such shares intended to be disposed of, the holder or holders of which shall
have so requested registration thereof, to be registered under the Securities
Act so as to permit the sale or other disposition (in accordance with the
intended methods thereof as aforesaid) by the holder or holders of the shares
so registered, subject to the limitations set forth in Section 7(c). The


                                     - 3 -


<PAGE>   4


Company specifically covenants and agrees that it will use all reasonable
efforts to include such shares in any registration statement filed at the
request of Resource investors Management Company ("RIMCO") Or any affiliate
thereof filed by reason Of any registration rights granted Pursuant to the
contemplated investment in various debt instruments and related securities by
various limited partnerships affiliated with RIMCO (the "RIMCO Partnerships").
To the extent that the RIMCO Partnerships do not make such investment or no
registration statement is filed on their behalf within 24 months of the
execution date hereof, the Company shall, if permitted under applicable rules
and regulations of the Securities and Exchange Commission promptly cause the
Stock to be included on a registration statement on Form S-8, or if not so
permitted, on the next registration statement filed by the Company (other than
a registration effected solely to implement an employee benefit plan or solely
with respect to a transaction to which Rule 145 under the Securities Act is
applicable).

               (c) Limitations on Registration. If the Company gives notice
Pursuant to Section 7(b) for the purpose of permitting registration (whether
involving an underwritten or other offering) of Shares, the Company shall have
the right to determine the aggregate size of the offering and to limit the
number of Shares to be registered by the holders of Registrable Stock pursuant
to Section 7(b), including the right to exclude all shares to be sold on behalf
of holders of Registrable Stock if the Company's underwriters or financial
advisers determine such exclusion is necessary or advisable to insure a
successful offering of the Company securities. If the Company limits the number
of (but does not exclude) shares sold by selling shareholders, the maximum
number of shares to be registered on behalf of any holder of Registrable Stock
shall be determined by multiplying the number of shares of Registrable Stock
such holder has properly requested be registered by a fraction, the numerator
of which shall be the number of shares of Common Stock to be included in such
registration by all shareholders, and the denominator of which is the number of
shares of Common Stock validly requested to be included in such registration by
all holders of Common Stock having registration rights. All registration rights
with respect to any shares of Registrable Stock shall lapse and terminate at the
earlier of (i) such time as such shares have been actually registered once on a
registration statement on Form S-3 or S-8, (ii) such time as the holder thereof
has had the opportunity to register such shares hereunder and has declined or
failed to so register such shares, or (iii) such time as counsel for the
Company makes a good faith determination that all of the shares of Registrable
Stock may be sold into public markets under Rule 144 promulgated under the
Securities Act, or otherwise, in a period of nine months or less and that any
restrictive legend set forth on the shares of Registrable Shares pertaining to
securities law compliance may be removed. In addition, to the extent that any
existing registration rights of the Company conflict with the provisions of
this Section 7, the registration rights provided herein shall be subject to any
previously granted registration rights with respect to the Company securities
and shall be delayed or otherwise equitably subordinated to such prior rights
until such prior rights are satisfied. The foregoing limitations shall not
apply to the first registration statement filed on behalf of RIMCO or any of
the RIMCO Partnerships, provided that RIMCO consents to such inclusion.

                                    WARRANT

                     To Purchase Shares of Common Stock of

                       UNIVERSAL SEISMIC ASSOCIATES, INC.

     THIS CERTIFIES THAT, for value received, RONALD L. ENGLAND, whose address

entitled to purchase from UNIVERSAL SEISMIC ASSOCIATES, INC., a Delaware

77084-5051 (the "Company"), at any time from and after the date hereof, and

Period"), 100,000 fully paid and nonassessable shares of the Company's common
stock, $0.0001 par value (the "Common Stock"), at the price of $3.75 per Share
("Share Purchase Price"); subject, however, to the provisions and upon the
terms and conditions hereinafter set forth in this Warrant ("Warrant"). The
shares of Common Stock deliverable upon exercise of this Warrant shall be
referred to hereinafter collectively as the "Shares."

     1. Exercise; Issuance of Certificates; Payment for Shares.  The rights
represented by this Warrant may be exercised by the Holder, in whole or in
part, at any time or from time to time during the Exercise Period, upon
presentation and surrender of this Warrant to the Company, at its principal
office as set forth above, or at such other place as the Company may designate
written notice from the Holder stating that the Holder is exercising this
Warrant and specifying the number of Shares that the Holder desires to purchase
(the "Notice") and accompanied by payment of the applicable Share Purchase
Price for each Share so purchased and all federal and state taxes or other
governmental charge applicable to such exercise and issuance of the Shares.
Such payment shall be made, in cash or by certified, bank or cashier's check,
payable to the order of the Company. The Shares so purchased shall be deemed to
have been issued to the Holder as of the close of business on the business day
next following the date on which this Warrant shall have been surrendered to
the Company, along with the Notice and full payment for the Shares purchased.

purchased and, unless this Warrant shall have expired, a new Warrant
representing the number of Shares, if any, with respect to which this Warrant
shall not then have been

exercised, shall be delivered to the Holder within a reasonable time after the
Holder has complied with the provisions of this Section 1.

     2. Restrictions on Exercise or Transfer of Warrant The Holder may not sell,
assign, transfer or hypothecate this Warrant or any interest herein except as
set forth in the last sentence of this Section, and any attempt by the Holder
to do so shall be void. Neither this Warrant nor any interest herein may be
sold, assigned, transferred or hypothecated involuntarily or by operation of
law. The Company specifically understands and agrees that the Warrant shall be
fully transferable to any corporation of which the Holder is a director or
affiliate and has a 10% or more equity interest therein, provided that the
transferee specifically agrees to comply with the foregoing and the Holder has
a bona fide interest in such corporation and such transfer has not been made to
such corporation for the primary purpose of avoiding the foregoing transfer
restrictions.

     3. Reservation of Shares. The Company hereby agrees that at all times
during the Exercise Period there shall be reserved for issuance and delivery
upon exercise of this Warrant such number of Shares as shall be required for
issuance and delivery on exercise of this Warrant.

case of loss, theft or destruction, upon receipt by the Company of indemnity
satisfactory to the Company, or (ii) in the case of mutilation, upon
presentation, surrender, and cancellation of this Warrant. The Holder shall pay
all federal and state taxes or other governmental charge applicable to any
issuance of new Warrants under this Section 4.

     5. Rights of the Holder. The Holder shall not, by virtue of this Warrant,
be entitled to any rights of a shareholder in the Company, either at law or
equity. The rights of the Holder are limited to those expressed in the Warrant
and are not enforceable against the Company except to the extent set forth
herein.

     6. Adjustment and Other Events.

               (a) Definition. As used in this Section 6, "Stock" shall mean
share of the Company's capital stock of any class, whether now or hereafter
authorized, that has the right to participate in the distribution of earnings
and assets of the Company without limit as to amount or percentage. As of the
date hereof, Stock consists of 20,000,000 authorized shares of the Company's
common stock, $0.0001 par value per share.

               (b) Stock Dividend or Distribution. If the Company shall declare
any dividend or other distribution upon its outstanding Stock payable in Stock,
or shall subdivide its outstanding shares of Stock into a greater number of
shares, then, on the effective date of such dividend, distribution or
subdivision, the number of Shares that may thereafter be purchased


                                     - 2 -


<PAGE>   3


upon the exercise of the rights represented hereby shall be in proportion to
the increase through such dividend, distribution or subdivision, and the Share
Purchase Price shall be decreased in such proportion. In case the Company shall
at any time combine the outstanding shares of its Stock into a smaller number
of shares, then, on the effective date of such combination, the number of Shares
that may thereafter be purchased upon the exercise of the rights represented
hereby shall be decreased in proportion to the decrease through such
combination, and the Share Purchase Price shall be increased in such
proportion.

               (c) Notice of Adjustment and Other Events. The Company shall
give the Holder notice of any event requiring an adjustment as provided in
Subsection 6(b) at least ten days prior to the effective date of such event;
provided, however, that failure to give such notice shall not in any way
invalidate or otherwise limit or affect the validity or effectiveness of such
event.

               (d) Fractional Shares. No fractional shares of Common Stock or
scrip representing fractional shares of Common Stock shall be issued upon the
exercise of this Warrant, and the Company shall have no obligation to make any
cash payment with respect thereto.

               (e) Company-Held Stock. The number of shares of Stock of any
class at any time outstanding shall include all shares of Stock of that class
then owned or held by or for the account of the Company.

     7. Registration Rights.

               (a) Registrable Stock. As used in this Section 7, the term
"Registrable Stock" shall mean all Shares issued pursuant to the provisions of
this Warrant, but shall not include the Warrant.

               (b) Incidental Registration. In the event that the Company
proposes, at any time during the Exercise Period, to file a registration
statement on a general form of registration under the Securities Act of 1933,
as amended (the "Securities Act"), and relating to shares of Common Stock
issued or to be issued by it (other than a registration effected solely to
implement an employee benefit plan or solely with respect to a transaction to
which Rule 145 under the Securities Act is applicable), then it shall give
written notice of such proposal to all holders of Registrable Stock and any
other holders of securities of the Company having any rights to include
securities in such registration. Upon the written request of a holder or
holders of any shares of Registrable Stock given within ten days after receipt
of any such notice (stating the number of shares of Registrable Stock to be
disposed of and the intended method of disposition of such shares by such
holder or holders), the Company will use its best efforts to promptly cause all
such shares intended to be disposed of, the holder or holders of which shall
have so requested registration thereof, to be registered under the Securities
Act so as to permit the sale or other disposition (in accordance with the
intended methods thereof as aforesaid) by the holder or holders of the shares
so registered, subject to the limitations set forth in Section 7(c). The

                                     - 3 -


<PAGE>   4


Company specifically covenants and agrees that it will use all reasonable
efforts to include such shares in any registration statement filed at the
request of Resource Investors Management Company ("RIMCO") or any affiliate
thereof filed by reason of any registration rights granted pursuant to the
contemplated investment in various debt instruments and related securities by
various limited partnerships affiliated with RIMCO (the "RIMCO Partnerships").
To the extent that the RIMCO Partnerships do not make such investment or no
registration statement is filed on their behalf within 24 months of the
execution date hereof, the Company shall, if permitted under applicable rules
and regulations of the Securities and Exchange Commission promptly cause the
Stock to be included on a registration statement on form S-8, or if not so
permitted, on the next registration statement filed by the Company (other than
a registration effected solely to implement an employee benefit plan or solely
with respect to a transaction to which Rule 145 under the Securities Act is
applicable).

               (c) Limitations on Registration. If the Company gives notice
pursuant to Section 7(b) for the purpose of permitting registration (whether
involving an underwritten or other offering) of Shares, the Company shall have
the right to determine the aggregate size of the offering and to limit the
number of Shares to be registered by the holders of Registrable Stock pursuant
to Section 7(b), including the right to exclude all shares to be sold on behalf
of holders of Registrable Stock if the Company's underwriters or financial
advisers determine such exclusion is necessary or advisable to insure a
successful offering of the Company securities. If the Company limits the number
of (but does not exclude) shares sold by selling shareholders, the maximum
number of shares to be registered on behalf of any holder of Registrable Stock
shall be determined by multiplying the number of shares of Registrable Stock
such holder has properly requested be registered by a fraction, the numerator
of which shall be the number of shares of Common Stock to be included in such
registration by all selling shareholders, and the denominator of which is the
number of shares of Common Stock validly requested to be included in such
registration by all holders of Common Stock having registration rights. All
registration rights with respect to any shares of Registrable Stock shall lapse
and terminate at the earlier of (i) such time as such shares have been actually
registered once on a registration statement on Form S-3 or S-8, (ii) such time
as the holder thereof has had the opportunity to register such shares hereunder
and has declined or failed to so register such shares, or (iii) such time as
counsel for the Company a good faith determination that all of the shares of
Registrable Stock may be sold into public markets under Rule 144 promulgated
under the Securities Act, or otherwise, in a period of nine months or less and
that any restrictive legend set forth on the shares of Registrable Shares
pertaining to securities law compliance may be removed. In addition, to the
extent that any existing registration rights of the Company conflict with the
provisions of this Section 7, the registration rights provided herein shall be
subject to any previously granted registration rights with respect to the
Company securities and shall be delayed or otherwise equitably subordinated to
such prior rights until such prior rights are satisfied. The foregoing
limitations shall not apply to the first registration statement filed on behalf
of RIMCO or any of the RIMCO Partnerships, provided that RIMCO consents to such
inclusion.

such combination, and the Share Purchase Price shall be increased in such
proportion.

                         (iii) prepare and file without expense to the Holder
          and such owners any necessary amendment or supplement to such
          registration statement or prospectus as may be necessary to comply
          with Section 10(a)(3) of the Securities Act or advisable in
          connection with the proposed distribution of the Shares by the Holder

<PAGE>   4
          to do business or file a general consent to service of process as a
          condition to the qualification of such securities;

                         (v)   notify the Holder and such owners of any stop
          order suspending the effectiveness of the registration statement and
          use its reasonable best efforts to remove such stop order;

                         (vi)  undertake to keep said registration statement
          and prospectus effective for a reasonable period of time; and

                         (vii) furnish to the Holder and such owners, as soon
          as available, copies of any such registration statement and each
          preliminary or final prospectus and any supplement or amendment
          required to be prepared pursuant to the foregoing provisions of this
          Section 7, all in such quantities as such owners may from time to
          time reasonably request. Upon written request, the Company shall also
          furnish to each owner, without cost, one set of the exhibits to such

pursuant to this Section 7 for the purpose of permitting registration (whether
involving an underwritten or other offering) of Shares, the Company shall have
the right to determine the aggregate size of the offering and to limit the
number of shares to be registered at the request of Holder or any record owners
of Shares issued hereunder ("Registrable Stock") pursuant to Section 7(a),
including the right to exclude all shares to be to be registered at the request
of Holder or any record owners of Registrable Stock if the Company's
underwriters or financial advisers determine such exclusion is necessary or
advisable to insure a successful offering of the Company securities. If the
Company limits the number of (but does not exclude) such Shares, the maximum
number of shares to be registered on behalf of any holder of Registrable Stock
shall be determined by multiplying the number of shares of Registrable Stock
such holder has properly requested be registered by a fraction, the numerator
of which shall be the number of shares of Common Stock to be included in such
registration by all selling shareholders, and the denominator of which is the
number of shares of Common Stock validly requested to be included in such
registration by all holders of Common Stock having registration rights. All
registration rights with respect to any shares of Registrable Stock shall lapse
and terminate at the earlier of (i) such time as such shares have been actually
registered once on a registration statement on Form S-3 or S-8, (ii) such time
as the holder thereof has had the opportunity to register such shares hereunder
and has declined or failed to so register such shares, or (iii) such time as
counsel for the Company makes a good faith determination that all of the shares
of Registrable Stock may be sold into public markets under Rule 144 promulgated
under the Securities Act, or otherwise, in a period of nine months or less and
that any restrictive legend set forth on the shares of Registrable Shares
pertaining to securities law compliance may be removed. In addition, to the
extent that any existing registration rights of the Company conflict with the
provisions of this Section 7, the registration rights provided herein shall be
subject to any previously granted registration rights with respect to the
Company securities and shall be delayed or otherwise equitably subordinated to
such prior rights until such prior rights are satisfied.

the time of the pendency of any request of the registration of this Warrant or
Shares, such securities may be publicly sold by the holder thereof without
registration under the Securities Act pursuant to Rule 144 promulgated
thereunder or otherwise, such holder shall not be entitled to require the
Company to register such securities pursuant to the Securities Act.

or other disposition of such securities; except that no such agreement shall be
required from any person purchasing Shares issued or issuable upon exercise of
this Warrant pursuant to a registration statement effective under the
Securities Act. The Holder agrees that, prior to the disposition of any Shares
purchased pursuant to the exercise hereof under circumstances that might
require registration of such Shares under the Securities Act, or any similar
federal or state statute then in force, the Holder shall give written notice to
the Company expressing his intention as to the disposition to be made of such
Shares. Promptly upon receiving such notice, the Company shall present copies
thereof to its counsel. If, in the opinion of the Company's counsel, the
proposed disposition does not require registration of such Shares under the
Securities Act, or any similar federal or state statute then in force, the
Company shall, as promptly as practicable, notify the Holder of such opinion,
and the Holder shall then be entitled to dispose of such Shares, but only
strictly in accordance with the terms of the notice delivered by the Holder to
the Company and any qualifications or limitations contained in the opinion of
the Company's counsel.

1.   LEASE OF EQUIPMENT. The Agreement establishes the general terms and
     conditions for Lessee to lease equipment from Lessor. The Agreement will
     be incorporated into each individual lease ("Lease") executed by Lessor
     and Lessee. A Lease lists the equipment to be leased ("Equipment") and
     includes other information particular to that Lease. If a provision of a
     Lease conflicts with a provision of the Agreement, the Lease prevails.

2.   TERM; ACCEPTANCE.

     (a)  The term of the Lease ("Lease Term"), unless terminated earlier,
     consists of an Interim Lease Term, a Base Lease Term, and any Renewal
     Term, all as specified in the Lease.

     (b)  Lessee -- not Lessor -- is responsible for selecting the Equipment
     and assuring that it is delivered and properly installed. The Equipment
     is considered irrevocably accepted by Lessee on the date the


                                                                 Lessor  /s/
                                                                        -----

                                                                 Lessee  /s/
                                                                        -----
<PAGE>   2
                                      2

     Lease Term begins. "Acceptance" means that the Lessee represents and
     warrants that the Equipment: (i) has been delivered to and is in the
     possession of Lessee; (ii) has been fully inspected by Lessee or its
     qualified agent; (iii) is suitable for the purpose intended by Lessee;
     (iv) is in good order, operating condition, and repair and has been
     properly installed (subject to minor undischarged obligations of
     suppliers, manufacturers, or installers under their agreements and
     warranties); (v) meets all recommended or applicable safety and
     environmental laws, regulations, and standards; (vi) is clear of Lessee
     Liens (as defined in Paragraph 4); and (vii) has been insured as required
     by Paragraph 6.

     (c) Lessor is not obligated to purchase the Equipment and enter into a
     Lease unless, as of the beginning of the Lease Term: (i) there are no
     Lessee Liens (as defined in Paragraph 4) on the Equipment; (ii) all
     Lessee's Representations and Warranties in Paragraph 9 are true and
     correct; (iii) no Event of Default (as defined in Paragraph 13) would
     exist upon signing the Lease, and no Event of Default exists as to other
     Leases under the Agreement; (iv) there has been no material adverse change
     in Parent's financial condition since June 30, 1995; (v) Lessor's due
     diligence has been completed to its satisfaction; and (vi) all documents
     attached to the Lease are satisfactory in form and substance to Lessor.
     The Total Equipment Cost (as specified in the Lease) may not exceed
     $4,300,000, and Acceptance of all Equipment must occur before December 31,
     1995.

3.   RENT; TAXES; LATE CHARGES.

     (a) Rent. Lessee promises to pay Lessor, throughout the Lease Term, the
     rental payments ("Rent") in the amounts and on the dates specified in the
     Lease. Rent is due and payable whether or not Lessee receives written
     notice from Lessor. Lessor intends to send monthly Rent invoices to
     Lessee, but Lessee's obligation to pay Rent on time does not depend on its
     receipt of monthly invoices. If an individual Rent payment or other amount
     due under the Lease is greater than $50,000, Lessee will make the payment
     by bank transfer of immediately available funds.

     (b) Taxes. Lessor will pay, and Lessee promises to reimburse Lessor, for
     all taxes, fees, duties, imposts, assessments, or other charges ("Taxes")
     that are imposed on Lessor or its affiliates, now or in the future, in
     connection with the Equipment (including its purchase by Lessor and,
     during the Lease Term, its ownership, leasing, use, and possession), and
     Lessor will make the necessary filings for Taxes. Taxes include interest,
     penalties, and fines (unless caused solely by the act or omission of
     Lessor), but Taxes exclude taxes on or measured by Lessor's net income or
     gross receipts. Taxes include those imposed by federal, state, local, and
     foreign authorities, whether imposed directly on Lessor, on Lessee, on the
     Equipment, or on a Lease. For purposes of the Agreement, Taxes are
     included within the meaning of the term "Rent."

     (c) Late Charges. If Lessee is late in paying Rent or any other amount
     under the Lease, Lessee will pay Lessor, as additional Rent, a late charge
     at a rate of 1.5 percent of the unpaid sum for each full or partial month
     that the sum remains unpaid. Payments will be applied first to late
     charges, then to Rent or other amounts owed by Lessee.


                                                                 Lessor  /s/
                                                                        -----
                                                                 Lessee  /s/
                                                                        -----

4.   CHARACTERISTICS OF LEASE.

     (a) Non-Terminable Net Lease. The Lease is a net lease and cannot be
     terminated by Lessee. Lessee's obligation to pay Rent and other amounts
     due under the Lease is ABSOLUTE AND UNCONDITIONAL, not subject to set-off,
     counterclaim, delay, or modification for any reason, including failure of
     the Equipment to perform as specified by a supplier or manufacturer.

     (b) Title; UCC Article 2A. The Equipment is separately identifiable
     personal property and is not considered a fixture or affixed to real
     estate. Title to the Equipment remains with Lessor. The Lease is a true
     lease for tax purposes and is a "finance lease" as defined in Article 2-A
     - Leases of the Uniform Commercial Code ("UCC Article 2A"); this is not a
     sale. If Lessor provides tags or labels indicating Lessor's ownership of
     the Equipment, Lessee will affix and maintain the tags or labels on the
     Equipment.

     (c) Liens. Lessee at its expense will take actions Lessor deems reasonably
     necessary to prevent third persons from acquiring or maintaining a right
     or interest in the Equipment. Lessee will not place, or allow to be
     placed, a mortgage, pledge, lien, security interest, or encumbrance of any
     kind on the Equipment (a "Lessee Lien"). Lessee is not responsible for a
     Lessor Lien, which arises out of a transaction unrelated to the Agreement,
     to which Lessor is a party and to which Lessee is not a party. If a Lessee
     Lien is placed on the Equipment, Lessee will promptly notify Lessor and at
     Lessee's expense clear the Lessee Lien within 30 days after learning of it
     or sooner if necessary to prevent losing possession of the Equipment or to
     prevent a diminution or change of Lessor's rights in the Equipment;
     provided however, so long as no Event of Default is continuing, if Lessee
     within such 30 day period initiates and at all times diligently pursues
     the appropriate court or administrative action seeking to clear the Lessee
     Lien, Lessee will have an additional 90 days from the end of such 30 day
     period to clear it.

     (d) Lessor's Rights; UCC Financing Statements. Lessee at its expense will
     promptly take action as Lessor reasonably requests to protect Lessor's
     rights under the Agreement, including without limitation the signing of
     UCC financing statements in jurisdictions Lessor considers necessary.
     Lessor will prepare the UCC financing statements and present them to
     Lessee for its signature. Return of the executed statements to Lessor is a
     condition prior to closing, and Lessee agrees to sign continuing
     statements, as necessary. Lessor may choose to file the UCC financing
     statements, and Lessee will reimburse Lessor for the filing fees and the
     outside service and administration fees. The execution and filing of such
     statements is precautionary (except where the Equipment is considered a
     fixture for UCC purposes) and does not affect the true lease character of
     the Lease for tax purposes or the "finance lease" character of the Lease
     under UCC Article 2A.

     (e) Quiet Possession. So long as no Event of Default is continuing,
     neither Lessor nor a third person claiming through Lessor will interfere
     with Lessee's right of quiet possession of the Equipment.


                                                                 Lessor  /s/
                                                                        -----
                                                                 Lessee  /s/
                                                                        -----

5.   OPERATION AND MAINTENANCE.

     (a) Use. Lessee will maintain sole possession and control of the
     Equipment. Lessee will use the Equipment solely in the normal conduct of
     its business in a careful manner according to the supplier's and
     manufacturer's instructions and in compliance with laws, regulations, and
     insurance requirements. Lessee will pay all costs, claims, damages, fees,
     and other amounts arising out of the possession, use, or maintenance of
     the Equipment. Lessee has the right and the obligation to assert directly
     against the supplier or manufacturer of the Equipment all claims regarding
     the Equipment, and Lessee will give Lessor prompt written notice of the
     terms of any settlement. Lessee at its expense will maintain the Equipment
     in good working order and repair to maintain the utility, operating
     efficiency, value, and remaining useful life of the Equipment, reasonable
     wear and tear resulting solely from proper use excepted; the Equipment
     must remain capable of performing its intended function efficiently and
     according to the supplier's and manufacturer's specifications. All
     replacement parts must meet the specifications of the supplier or
     manufacturer and have at least the utility and value of those replaced.
     Lessee will maintain accurate maintenance and inspection records on the
     Equipment and provide copies of such records to Lessor upon request. After
     the supplier's or manufacturer's warranty ends, Lessee at its expense
     will, unless waived by Lessor, enter into a maintenance agreement with the
     supplier or manufacturer (or another maintenance contractor approved by
     Lessor) for maintenance of the Equipment during the remainder of the Lease
     Term.

     (b) Modifications. Upon Lessor's prior written consent which will not be
     unreasonably withheld, Lessee at its expense has the right to make
     modifications, alterations, renovations, or improvements to the Equipment
     ("Modifications"), so long as such Modifications (i) do not damage or
     impair the utility, operating efficiency, value, or remaining useful life
     of the Equipment and (ii) may be removed without damaging the Equipment.
     Lessee at its expense will make Modifications during the Lease Term that
     are required by law, regulation, or insurance policy. A Modification that
     is not a Severable Modification (as defined below) becomes the property of
     Lessor and constitutes Equipment for all purposes under the Lease. A
     Severable Modification is a Modification that is readily removable and
     severable, is not a replacement or substitution for part of the Equipment,
     and is not required by law, regulation, or insurance policy. Lessee may
     remove a Severable Modification during or at the end of the Lease Term. A
     Severable Modification that is not removed at the end of the Lease Term
     becomes the property of Lessor, except that upon Lessor's request Lessee
     at its expense will remove a Severable Modification and return the
     Equipment to the condition required by the Lease.

     (c) Inspection. Upon two business days advance notice and during
     reasonable business hours but without disruption to Lessee's business,
     Lessee will allow Lessor or its representative to inspect the Equipment,
     to observe its operation with the assistance of Lessee's personnel, and to
     examine and copy maintenance and inspection records.

     (d) Movement of Equipment. Lessee may move all items of Equipment within
     the continental United States by giving Lessor 30 days prior notice. On
     January 31 of each year throughout the Lease Term, Lessee will provide
     Lessor with a written, monthly report detailing the number of days


                                                                 Lessor  /s/
                                                                        -----
                                                                 Lessee  /s/
                                                                        -----

                                      5

     in the month that the Equipment spent at any location (by county and 
     state).

6.   INSURANCE.

     (a) Property. Throughout the Lease Term, Lessee will purchase and maintain
     an all risk physical damage policy insuring the Equipment against loss and
     damage in an amount not less than the greater of full replacement value of
     the Equipment or the Stipulated Loss Value as calculated under Paragraph
     7(b). The deductible or self-insurance retention applicable to the policy
     may not exceed the amount specified in the Lease. Lessor will be named as
     loss payee.

     (b) Liability. Throughout the Lease Term, Lessee will purchase and
     maintain a commercial general liability insurance policy relating to the
     Equipment protecting against claims alleging bodily injury (including
     personal injury) and property damage with a combined single limit per
     occurrence not less than the amount specified in the Lease. The deductible
     or self-insurance retention applicable to the policy may not exceed the
     amount specified in the Lease. The policy will be on an occurrence form,
     and Lessor will be named as additional insured.

     (c) Policies and Premiums. Lessee will deliver proof of insurance coverage
     to Lessor before the beginning of the Lease Term and at least 30 days
     before expiration of insurance coverage during the Lease Term. Proof of
     insurance coverage consists of a certificate of insurance and, at Lessor's
     option, the complete insurance policy. The insurance company selected by
     Lessee must be reasonably acceptable to Lessor, and the insurance policy
     must be in form and substance reasonably satisfactory to Lessor. Insurance
     policies will provide that (i) Lessor will be given 30 days prior written
     notice of any alteration or cancellation of the coverage, and (ii)
     Lessor's status as loss payee and additional insured will not be
     invalidated by action or inaction by Lessee. Regarding all insurance,
     Lessee will pay the premiums. Lessee agrees that Lessor may obtain a
     security interest in the proceeds of all insurance policies directly
     relating to the Equipment.

7.   RISK OF LOSS OR DAMAGE.

     (a) Loss. Lessee assumes all risk of loss, theft, and damage to the
     Equipment from any cause ("Loss"). A Loss does not relieve Lessee of its
     obligation to pay Rent or to perform other obligations under the Lease.
     Lessor incurs no liability to Lessee or third persons for loss of
     business, loss of profits, or other direct or consequential damages
     relating to a Loss. Lessee will immediately give Lessor notice of a Loss
     (except that no notice is required for cosmetic damage that does not
     affect the operating performance of the Equipment); if notice is given
     orally, it will be confirmed in writing within 15 days. If less than a
     Total Loss (as defined below) occurs, Lessee will promptly restore the
     Equipment to the condition required by Paragraph 5.

     (b) Total Loss. After receiving Lessee's notice of a Loss or upon Lessor's
     inspection, if Lessor determines that all or substantially all the
     Equipment is damaged beyond repair, lost, stolen, condemned, or
     confiscated ("Total Loss"), Lessor will notify Lessee in writing that a
     Total Loss has occurred and that Lessee is obligated to continue paying
     Rent until Lessee pays to Lessor a


                                                           Lessor   /s/
                                                                  -------
                                                           Lessee   /s/
                                                                  -------
<PAGE>   6
                                      6

     Total Loss Payment. The Total Loss Payment will be due on the next Rent
     payment date following the earlier of (i) receipt of insurance proceeds
     relating to the Total Loss or (ii) 90 days from the date of the Total
     Loss. The Total Loss Payment will equal the Rent and other amounts due
     Lessor up to and including such next Rent payment date plus the Stipulated
     Loss Value. The Stipulated Loss Value, which represents liquidated damages
     for loss of a bargain, consists of: (i) the Total Equipment Cost specified
     in the Lease for the Equipment subject to the Total Loss, multiplied by
     (ii) the percentage factor for the next Rent payment date shown on the
     Table of Stipulated Loss Values attached to the Lease, plus (iii) Taxes
     imposed on Lessor relating to the Total Loss, if any.

     After Lessor receives the Total Loss Payment, the Lease on the Equipment
     subject to the Total Loss will terminate, and Lessor will transfer the
     Equipment to Lessee on an "as is, where is" basis without recourse and
     without representation or warranty (express or implied), except that the
     Equipment will be clear of Lessor Liens.

     (c) Insurance Proceeds. Proceeds received at any time by Lessor or Lessee
     from Lessee's insurer on a Total Loss or Loss will be distributed promptly
     as follows.

         (i) Proceeds on a Total Loss will be distributed to Lessor, and Lessee
         irrevocably appoints Lessor as Lessee's attorney-in-fact to endorse
         checks directly relating to such proceeds. Such proceeds will reduce
         or discharge Lessee's obligation to pay the Total Loss Payment, and
         any excess of such proceeds over the Total Loss Payment will be
         retained by Lessor.

         (ii) Proceeds on a Loss other than a Total Loss will be distributed
         to Lessee to reimburse it for the expense it actually incurs to
         restore the Equipment (Lessee will provide Lessor with satisfactory
         documentation of the actual restoration costs); provided however if
         an Event of Default is continuing, the proceeds will be distributed
         to Lessor, and Lessee irrevocably appoints Lessor as Lessee's
         attorney-in-fact to endorse checks directly relating to such proceeds,
         which will be applied against the Default Payment, if any, under
         Paragraph 14.

8.   DISCLAIMER OF WARRANTY; LIMITATION OF LIABILITY.

     (a) LESSOR LEASES THE EQUIPMENT TO LESSEE "AS IS". LESSEE SELECTED THE
     EQUIPMENT USING ITS OWN JUDGMENT AND EXPRESSLY DISCLAIMS RELIANCE UPON ANY
     STATEMENTS, REPRESENTATIONS, OR WARRANTIES MADE BY OR ON BEHALF OF LESSOR.
     EXCEPT FOR LESSEE'S RIGHT OF QUIET POSSESSION, LESSOR MAKES NO WARRANTY OR
     REPRESENTATION (EXPRESS OR IMPLIED) RELATING TO, WITHOUT LIMITATION: THE
     DESIGN, QUALITY, OR CONDITION OF THE EQUIPMENT; MERCHANTABILITY OR FITNESS
     OF THE EQUIPMENT FOR ANY PARTICULAR PURPOSE; TITLE TO THE EQUIPMENT;
     INFRINGEMENT OR INTERFERENCE WITH INTELLECTUAL PROPERTY RIGHTS;
     ACCOUNTING, FINANCIAL, OR TAX TREATMENT OR THE LIKE RELATING TO THE
     EQUIPMENT OR THE LEASE; OR ANY OTHER WARRANTY OR REPRESENTATION ARISING
     FROM


                                                                 Lessor  /s/  
                                                                        ----- 
                                                                 Lessee  /s/  
                                                                        ----- 
<PAGE>   7
                                       7

     COURSE OF DEALING OR USAGE OF TRADE LESSEE EXPRESSLY WAIVES ANY RIGHT TO
     MAKE CLAIMS AGAINST LESSOR BASED ON BREACH OF WARRANTY OR BASED ON
     MISREPRESENTATION.

     (b) LESSOR IS NOT LIABLE FOR ANY LOSS OR DAMAGE DIRECTLY OR INDIRECTLY
     ARISING FROM LESSEE'S POSSESSION, OPERATION, MAINTENANCE, OR REPAIR OF THE
     EQUIPMENT. IN ANY EVENT, LESSOR IS NOT LIABLE FOR CONSEQUENTIAL, SPECIAL,
     OR INCIDENTAL DAMAGES.

     (c) Lessor assigns to Lessee (to the extent assignable) rights Lessor has
     under warranties of a supplier or manufacturer of the Equipment, and such
     rights will be automatically reassigned to Lessor upon return of the
     Equipment to Lessor or upon repossession of the Equipment by Lessor.

     (d) If more than one Lessee is named in a Lease, the liability of each is
     joint and several.

9.   REPRESENTATIONS AND WARRANTIES OF LESSEE. Lessee represents and warrants
     the following to Lessor.

     (a) Legal Corporation. Lessee is a duly organized corporation under the
     laws of its state of incorporation and is in good standing under the laws
     of each jurisdiction in which it conducts business. Lessee has taken all
     corporate actions and has obtained all necessary corporate approvals to
     execute the Agreement, the Lease, and related documents.

     (b) Legal Agreement. The Agreement and the Lease are legal, binding
     obligations of Lessee and are enforceable against Lessee for the benefit
     of Lessor and its successors and assigns. Lessee's performance of its
     obligations do not and will not contravene (i) any law, regulation, or the
     like or (ii) the provisions of, or constitute a default under, any other
     agreement of Lessee.

     (c) Legal Actions and Defaults. On the dates Lessee executes the Agreement
     and the Lease, Lessee

        (i) is not a party to pending actions (and knows of no threatened
        actions) before a court, arbitrator, or government agency,

        (ii) is not in default under an obligation of borrowed money, for the
        deferred purchase price of property, or for the payment of rent under
        any lease agreement, and

        (iii) complies with all environmental laws, regulations, and standards

     that either individually or in the aggregate would adversely and
     materially affect Lessee's financial condition or its ability to perform
     its obligations under the Agreement and the Lease.

     (d) Financial Information. The financial information that Parent provided
     and will provide to

                                                    Lessor  /s/

     Lessor was and will be materially true and complete. As of the beginning
     of the Lease Term, there has been no material adverse change in Parent's
     financial condition since Lessor reviewed Parent's financial information
     prior to execution of the Agreement. In the two preceding sentences, the
     concept of "material" is defined under Generally Accepted Accounting
     Principles ("GAAP").

10.  FINANCIAL INFORMATION; OFFICER'S CERTIFICATE.

     (a) Parent will provide Lessor the following financial information during
     the Lease Term:

        (i) within 120 days of the end of Parent's fiscal year, a consolidated
        balance sheet of Parent (and its subsidiaries) and related statements
        of income and cash flow, prepared under GAAP, and certified by Parent's
        independent certified public accountant (or Form 10K if filed with the
        Securities and Exchange Commission ("SEC"));

        (ii) within 60 days of the end of each of Parent's first three fiscal
        quarters, a consolidated balance sheet of Parent (and its subsidiaries)
        and related statements of income and cash flow, prepared under GAAP,
        and certified by, Parent's comptroller, chief financial officer, or
        president (or Form 10Q if filed with the SEC);

        (iii) within 30 days after filing, all reports, forms, and other
        filings, if any, Parent makes to the SEC (or comparable government
        agency in a foreign country); and

        (iv) other financial information regarding the creditworthiness of
        Parent as Lessor may reasonably request.

     (b) Within 60 days of the end of each of Lessee's first three fiscal
     quarters and within 120 days of the end of Lessee's fiscal year, Lessee
     will provide a certificate of an authorized officer of Lessee stating: (i)
     there exists no Event of Default under Paragraph 13; and (ii) there exists
     no event with the lapse of time or the giving of notice or both would
     constitute an Event of Default under Paragraph 13.

11.  GENERAL INDEMNITY. Lessee agrees to defend, indemnify on an after-tax
     basis, and hold harmless Lessor (including its officers, directors,
     employees, agents, successors, and assigns) against claims and losses
     (including reasonable legal expenses) related in any way to the Agreement,
     the Lease, or the Equipment unless such claims or losses are directly
     caused by the gross negligence or willful misconduct of Lessor. Lessor
     will give Lessee prompt notice of a claim or action brought against Lessor
     related to an indemnifiable event. Lessee at its expense will control the
     defense of the claim or action, provided that: (i) no Event of Default is
     continuing; (ii) Lessor must reasonably approve defense counsel selected
     by Lessee (unless counsel is appointed by Lessee's insurer or
     underwriter); (iii) Lessor must approve of any settlement, which approval
     will not be unreasonably delayed or withheld; and (iv) Lessor at its
     expense may elect to participate with Lessee in the defense.


                                                           Lessor   /s/
                                                                 ----------
                                                           Lesse   /s/

12.  TAX INDEMNITY.

     (a) Definitions for this Paragraph.

        (i) "Lessor" includes Lessor's consolidated federal taxpayer group.

        (ii) "Code" means the Internal Revenue Code of 1986, as amended from
        time to time, or its successor.

        (iii) "MACRS Deductions" means the deductions under Section 168 of the
        Code determined by the modified Accelerated Cost Recovery System on the
        total invoice cost of any item of Equipment for its property class,
        using the accelerated method in Section 168(b)(1) of the Code.

        (iv) "Tax Loss" means, regarding the computation of Lessor's federal,
        state, local, or foreign taxes:

            (1) the benefits of MACRS Deductions are lost, delayed, disallowed,
            or recaptured;

            (2) Lessor becomes liable for additional tax because of a
            prepayment of Rent or because a Modification is made to the
            Equipment; or

            (3) the statutory full-year marginal federal tax rate (including
            any surcharge) for corporations increases above 35 percent (if such
            tax rate decreases from 35 percent, Lessor will adjust accordingly
            the Rent and Stipulated Loss Value).

        (v) "Lessor's Net Return" means the originally contemplated after-tax
        net return assumed in Lessor's economics with the same periodicity.

        (vi) "Tax Indemnification Payment" means the tax adjustment (taking
        into account applicable interest, penalties, additions, and taxes)
        discounted at a rate necessary to maintain Lessor's Net Return
        following a Tax Loss throughout the Lease Term.

     (b) Representations and Warranties. Lessee represents and warrants that:
     (i) the reasonably estimated useful life of the Equipment at the beginning
     of the Lease Term exceeds the sum of the Interim and Base Lease Terms (and
     any Renewal Term with fixed rent) by the greater of one year or 20 percent
     of the estimated useful life; (ii) the reasonably estimated fair market
     value of the Equipment at the end of the Base Lease Term (or at the end of
     any Renewal Term with fixed rent) is at least 20 percent of the Total
     Equipment Cost (as specified in the Lease), without considering any
     increase or decrease for inflation or deflation during the Lease Term;
     (iii) the Equipment will be used only in the United States as part of
     Lessee's normal business operations; and (iv) the Equipment is, and will
     be used by Lessee so as to remain during the Lease Term, property eligible
     for MACRS Deductions, for so long as MACRS deductions are available under
     the Code.

                                                         Lessor  /s/
                                                               -----------
                                                         Lessee  /s/
                                                               -----------

                                                                     
<PAGE>   10


                                       10


     (c) Tax Indemnification Payment. If a Tax Loss occurs, Lessor will notify
     Lessee in writing, and Lessee will pay Lessor the required Tax
     Indemnification Payment within 30 days of the notice. A Tax Loss occurs
     upon the earliest of: (i) the occurrence of an event (such as a
     disposition or change in use of the Equipment) that causes the Tax Loss;
     (ii) Lessor's payment of the tax increase resulting from the Tax Loss;
     (iii) the date on which the Tax Loss is realized by Lessor; or (iv) the
     adjustment of Lessor's tax return to reflect the Tax Loss. Lessee has no
     obligation to make a Tax Indemnification Payment on a Tax Loss arising
     solely as a direct result of: (i) Lessor's failure to timely and properly
     claim Tax Benefits in its tax return other than as a result of a change in
     the Code or applicable regulations, unless in the opinion of Lessor's tax
     counsel there is no reasonable basis for such claim; or (ii) Lessor's
     failure to have sufficient taxable income before application of MACRS
     Deductions to offset the full amount of such deductions, other than as a
     result of a change in the Code or applicable regulations.

13.  DEFAULT. An Event of Default means any of the following:

     (a) Failure to Pay, Lessee fails to pay Rent or any other amount as it
     becomes due under any Lease or under any other agreement between Lessor
     and Lessee, and full payment is not received by Lessor within 5 days of
     Lessor's written notice to Lessee.

     (b) Liens; Insurance. Lessee fails to perform under Paragraphs 4(c)
     [Lessee Liens], or Lessee fails to obtain and maintain throughout the
     Lease Term the insurance required by Paragraph 6.

     (c) Misrepresentation. Lessee's representations and warranties in
     Paragraphs 2(b), 9, or 12(b) were materially inaccurate or misleading when
     made.

     (d) Assignments; Transfer. Lessee makes an unauthorized assignment of the
     Agreement or the Lease, or Lessee makes an unauthorized transfer,
     sublease, pledge, or the like of the Equipment.

     (e) Corporate Existence. Lessee ceases to be an ongoing concern; Lessee
     ceases to be in good standing under the laws of each jurisdiction in which
     it conducts business, and such lack of good standing is not cured within
     15 days of written notice from Lessor; Lessee terminates its corporate
     existence or enters into a merger or consolidation in which it is not the
     surviving entity; or Lessee transfers all or substantially all of its
     assets (unless the entity acquiring the assets assumes all duties and
     obligations of Lessee under the Lease, and Lessor is satisfied in its sole
     discretion with the creditworthiness of the new entity).

     (f) Insolvency; Bankruptcy. Lessee becomes insolvent; Lessee consents to
     the appointment of a receiver, trustee, or the like for a substantial part
     of its property; Lessee makes a general assignment for the benefit of
     creditors; Lessee admits in writing its general inability to pay its debts
     when due; Lessee takes action seeking relief under bankruptcy or any
     insolvency law; or an action under bankruptcy or any insolvency law is
     begun against Lessee, and the action is not dismissed within 30 days.


                                                           Lessor   /s/
                                                                 --------------
                                                           Lessee   /s/
                                                                 --------------

                                                                      

<PAGE>   11
                                      11

     (g) Cross Default. Lessee does not cure within 30 days a default with
     respect to third persons under an obligation in excess of $500,000 for
     borrowed money, for the deferred purchase price of property, or for the
     payment of rent under any lease agreement.

     (h) Financial Covenants.

            1) Parent's leverage ratio exceeds 2:1 during the Lease Term.
            Leverage means Total Liabilities to Total Shareholders' Equity, as
            such terms are defined by GAAP.

            2) Parent makes a payment of dividends,

            3) Rick E. Trapp and Michael J. Pawelek fail to directly or
            indirectly maintain an aggregate of at least 25% ownership of
            Parent during the Lease Term.

     (i) Compliance Certificate. Lessee fails to provide the officer's
     certificate required under Paragraph 10(b) within ten days of written
     notice from Lessor.

     (j) Other Failure. Lessee fails to perform or observe any other
     obligation, condition, or requirement under the Lease or under any other
     agreement between Lessor and Lessee, and the failure is not cured within
     30 days after the earlier of (i) the date on which Lessee learns of the
     failure or (ii) the date of notice by Lessor to Lessee.

14.  REMEDIES. If an Event of Default occurs, Lessor may declare a default
     ("Default") by written notice to Lessee. Lessor may declare a Default on
     all Leases under the Agreement or, alternatively, on some or all of the
     Equipment or Leases. If Lessor declares a Default, Lessor may pursue one
     or more of the following remedies.

     (a) Default Payment. Without seeking return of the Equipment and upon
     written notice to Lessee specifying a payment date not earlier than 10
     days, Lessor may demand that Lessee pay a Default Payment to Lessor.
     Lessee acknowledges that the Default Payment represents liquidated damages
     necessary to compensate Lessor for the loss of a bargain caused by
     Lessee's Default and does not constitute a penalty. The Default Payment is
     an amount equal to the Rent and other amounts due Lessor up to and
     including the next Rent payment date plus the higher of:

        (i) the Stipulated Loss Value defined in Paragraph 7(b); or

        (ii) the present value of future Rents to the end of the Base Lease
        Term (or, as applicable, a Renewal Term) plus Lessor's reasonable then
        current assessment of the Fair Market Value of the Equipment at the end
        of the Base Lease Term (or, as applicable, a Renewal Term), both
        discounted at six percent. Fair Market Value means the price that a
        willing, knowledgeable buyer would pay for the Equipment in an arm's
        length transaction to a willing, knowledgeable seller under no
        compulsion to sell, assuming that the Equipment is installed and in use
        and is in the condition required by Paragraph 5 of the Agreement.





          

<PAGE>   12


                                       12

     If Lessee fails to make the Default Payment by the specified payment date,
     Lessee will pay to Lessor late charges as calculated in Paragraph 3(c).
     After Lessor receives the full amount of the Default Payment (including
     any late charges and any Taxes imposed on Lessor related to the transfer
     of the Equipment to Lessee), the Lease (or part of it) subject to the
     Default will terminate, and Lessor will transfer the applicable Equipment
     to Lessee on an "as is, where is" basis without recourse and without
     representation or warranty (express or implied), except that the Equipment
     will be clear of Lessor Liens.

     (b) Return or Repossession of Equipment.

            (1) Upon written notice to Lessee, Lessor may require Lessee at
            Lessee's expense to promptly return the Equipment according to the
            return provisions of the Lease. Alternatively, Lessor may require
            Lessee at its expense to place the Equipment in the condition
            required by the return provisions of the Lease and to gather the
            Equipment at the location or locations where the Equipment was
            originally delivered (or at a location or locations designated by
            Lessor in reasonable proximity to the original delivery points);
            Lessor may then take immediate possession of the Equipment by
            summary proceedings or otherwise and may remove it from Lessee's
            location, with no liability to Lessor.

            (2) Upon return or repossession of the Equipment, Lessor may sell
            or re-lease the Equipment in a commercially reasonable manner at a
            public or private sale. Lessor will use commercially reasonably
            efforts in good faith to mitigate the damages caused by Lessee's
            Default. Lessor's entire obligation to attempt to mitigate damages
            is stated in this subparagraph, and Lessee waives whatever
            additional rights it might have under laws or regulations to
            require mitigation.

            (3) If after making commercially reasonable efforts Lessor is not
            able to sell or re-lease the Equipment, Lessee will pay to Lessor,
            upon 10 days written notice, the Default Payment defined in
            Paragraph 14(a), and the Equipment will be transferred to Lessee
            according to Paragraph 14(a).

            (4) If Lessor is able to sell or re-lease the Equipment, Lessee
            will pay Lessor, upon 10 days written notice, the Default Payment
            defined in Paragraph 14(a) minus the Net Proceeds. The Net Proceeds
            of a sale are: (i) the total consideration received by Lessor on
            the sale; (ii) minus Lessor's incidental damages associated
            directly or indirectly with the sale (including reasonable charges
            and expenses for repair and restoration of the Equipment and of the
            landlord's premises, storage, freight, advertising, legal services,
            appraisal services, financing, sales commissions, and rent or other
            fees paid to a landlord).  The Net Proceeds of a re-lease are: (i)
            the present value of aggregate rents on the re-leased equipment
            throughout the remainder of the Lease Term under this Agreement
            (discounted at six percent); (ii) minus Lessor's incidental damages
            associated directly or indirectly with the re-lease (including
            reasonable charges and expenses of the type described in the
            previous sentence). In no event will Lessor be required to make a
            payment to Lessee under this subparagraph (b)(4).



                                                           Lessor   /s/
                                                                 ----------
                                                           Lessee   /s/
                                                                 ----------    

<PAGE>   13


                                       13

     (c) Cure By Lessor. Lessor may cure a Default or Event of Default (without
     relieving Lessee of its other obligations under the Agreement or the
     Lease), and Lessee will reimburse Lessor for all expenses incurred
     (including reasonable attorney fees).

     (d) Other Remedies. Lessor may pursue remedies available to it at law or
     in equity, including those under UCC Article 2A and suits for damages and
     for specific performance.

     (e) Election of Remedies. Lessor's remedies are cumulative. Lessor may
     pursue one or more remedies separately or concurrently. Lessor may pursue
     the same or different remedies with respect to individual items of
     Equipment within a Lease and with respect to individual Leases under the
     Agreement. Lessor's election of one remedy does not bar its pursuit of
     other remedies, provided that Lessor is not entitled to place itself in a
     better position than it would have been in had Lessee fully performed
     under the Lease.

     (f) Expenses; Agency. Lessee will pay Lessor's commercially reasonable
     charges, expenses, commissions, and the like (including reasonable
     attorney fees and any resulting Taxes) to pursue remedies under this
     paragraph. Lessee irrevocably appoints Lessor as Lessee's agent to execute
     and file documents necessary for Lessor to pursue remedies under this
     paragraph, except for those documents relating to actions at law or in
     equity.

     (g) Continuing Obligations. While Lessor is pursuing its remedies under
     this paragraph, Lessee remains liable under the Agreement and all Leases
     for all obligations that are not subject to the Default.

15.  END-OF-TERM OPTIONS.

     Provisions, if any, for renewal of a Lease, purchase of the Equipment, and
     return of the Equipment are specified in the Lease.

16.  GENERAL.

     (a) Assignment. Without Lessor's prior written consent, Lessee may not
     assign a Lease in whole or in part, nor may Lessee transfer, sublease, or
     pledge the Equipment in whole or in part; except that with 30 days prior
     notice to Lessor, Lessee may assign a Lease to a wholly-owned subsidiary
     of Lessee. In all cases of Lessee's assignment, transfer, sublease, and
     pledge (including an assignment to a wholly-owned subsidiary), Lessee will
     remain obligated under the Lease unless specifically released by Lessor.
     Lessor may assign a Lease in whole or in part without the consent of, or
     prior notice to, Lessee.

     (b) Timeliness. Time is of the essence regarding the Agreement and the
     Lease.

     (c) Non-Waiver. No course of dealing or failure to strictly enforce a
     provision of the Agreement or any Lease constitutes a waiver of the future
     performance of that provision.

VII.   ACCEPTANCE: REPRESENTATIONS AND WARRANTIES

(a) Lessee irrevocably accepts the Equipment described above according to 
Paragraph 2(b) of the Agreement.

(b) Lessee confirms, as of the execution date of this Lease, its
representations and warranties in Paragraphs 9 and 12 of the Agreement.

VIII.  END-OF-TERM OPTIONS

(a) At the end of the Base Lease Term, so long as no Event of Default is
continuing, Lessee must elect one of the following options:

     (i)  purchase all the Equipment; or

     (ii) renew the Lease for one or more terms, after which time either
     purchase or return all the Equipment.

(b) If Lessee fails to give timely notice (as specified below) of its election
of the purchase or return option, Lessee will be deemed to have elected the
renewal option.

(c) Lessor and Lessee anticipate that they will execute additional Leases
(Lease # 95-15b, Lease # 95-15c, and so forth) for multiple takedowns of
Equipment. Lessee's election of an end-of-term option for this Lease # 95-15a
will govern the end-of-term options for all Leases under Lease # 95-15. That
is, the end-of-term option for Lease # 95-15b, Lease # 95-15c, and so forth
will be the same end-of-term option that Lessee elects for this Lease # 95-15a.

1.     RENEWAL OPTION.

(a) To exercise its renewal option, Lessee must give Lessor irrevocable written
notice at least 180 days before the end of the Base Lease Term or, if
applicable, a Renewal Term.

(b) Lessee's first renewal option is for a period of one year ("First Renewal
Term") at a monthly Rent equal to 1.720005 percent of the Total Equipment Cost
specified in the Lease. At the end of the First Renewal Term, so long as no
Event of Default is continuing, Lessee has the option to renew the Lease for
successive periods of one year (each a "Successive Renewal Term") at the then
Fair Market Rent. "Fair Market Rent" means the rent that the Equipment would
command on the open market, assuming the Equipment is installed and in use and
is in the condition required by Paragraph 5 of the Agreement. Fair Market Rent
will be determined by mutual agreement between Lessor and Lessee. If Lessor and
Lessee are unable to reach agreement, Lessor will select an appraiser
reasonably acceptable to Lessee.


                                                              /s/    Lessor
                                                           ----------
                                                              /s/    Lessee
                                                           ----------
<PAGE>   19
 

                                       4


The valuation of the appraiser will become the binding Fair Market Rent. Lessee
will pay the appraiser's fees and expenses.

2.     PURCHASE OPTION.

(a) To exercise its option to purchase all Equipment listed on a Lease, Lessee
must give Lessor irrevocable written notice at least 180 days before the end of
the Base Lease Term or, if applicable, a Renewal Term.

(b) The purchase price at the end of the Base, Lease Term will be the greater
of: (i) 20 percent of the Total Equipment Cost (as specified in the Lease); or
(ii) the then Fair Market Value of the Equipment. The purchase price at the end
of a Renewal Term will be the then Fair Market Value. In addition to this
purchase price, Lessee will reimburse Lessor for all Taxes imposed on Lessor
(excluding taxes on any gain on the sale), plus all costs and expenses
(including reasonable attorney fees) payable by Lessor on the sale. Fair Market
Value means the price that a willing, knowledgeable buyer would pay for the
Equipment in an arm's length transaction to a willing, knowledgeable seller
under no compulsion to sell, assuming that the Equipment is installed and in
use and is in the condition required by Paragraph 5 of the Agreement. Fair
Market Value will be determined by mutual agreement between Lessor and Lessee.
If Lessor and Lessee are unable to reach agreement, Lessor will select an
appraiser reasonably acceptable to Lessee. The valuation of the appraiser will
become the binding Fair Market Value. Lessee will pay the appraiser's fees and
expenses.

(c) Upon receipt of the full purchase price and all other amounts then due
under the Lease, Lessor will transfer title to the Equipment to Lessee on an
"as is, where is" basis, without recourse and without representation or
warranty (express or implied), except Lessor warrants that the Equipment is
clear of Lessor Liens.

3.     RETURN OF THE EQUIPMENT.

(a) To exercise its option to return all Equipment listed on a Lease at the end
of a Renewal Term, Lessee must give Lessor irrevocable written notice at least
180 days before the end of a Renewal Term.

(b) Show Rights. Upon receiving reasonable notice from Lessor in the period 180
days before expiration or earlier termination of the Lease and without
disruption to Lessee's business, Lessee will make the Equipment available for
on-site operational inspections by potential purchasers, and Lessee will
provide personnel, power, and other operational requirements necessary to
demonstrate the electrical, mechanical, and operating systems of each item of
the Equipment.

(c) Restoration of the Equipment. By the end of the Lease Term, Lessee will at
its expense:


                                                                    /s/  Lessee
                                                                   -----
                                                                    /s/  Lessee
                                                                   -----

requirements necessary for the sale and continued commercial use of the
Equipment; (iii) ensure that the Equipment is clear of all Lessee Liens; and
(iv) restore the Equipment to its original condition as of the beginning of the
Lease Term (reasonable wear and tear resulting solely from proper use excepted)

to the following:

            -            ensure that the Equipment is clean, cosmetically
                         acceptable, and structurally sound with no noticeable
                         cracks, scratches or other visual, electrical or
                         mechanical damage. The Equipment must be in good
                         operating order, repair and condition free of any
                         hazardous waste material, and free from all rust and
                         corrosion, with no missing or damaged parts;

            -            ensure that all of the Equipment's systems, including
                         its electrical and telemetry systems, are able to
                         operate as designed in accordance with manufacturer's
                         specifications and within designed tolerances.

(d) Return. Lessee at its expense will:

          (1) At least 120 days before end of the Lease Term, provide to Lessor
          a detailed inventory of all components of the Equipment. The
          inventory should include, but not be limited to, a listing of model
          and serial numbers for all components.

          (2) At least 90 days before the end of the Lease Term, provide (or
          cause the suppliers or manufacturers to provide) to Lessor the
          following documents: (i) one set of service, operating, and software
          manuals including replacements and additions, such that all
          documentation is completely up-to-date; and (ii) one set of documents
          detailing configuration, operating requirements, maintenance and
          inspection records, and other technical data concerning the set-up
          and operation of the Equipment, including replacements and additions,
          such that all documentation is completely up-to-date.

          (3) At least 90 days before the end of the Lease Term, cause the
          manufacturer's representative or a qualified equipment maintenance
          provider acceptable to Lessor to perform a comprehensive physical
          inspection to test all material and workmanship of the Equipment and
          provide an in-depth field report to Lessor; if during the inspection,
          the authorized inspector finds that any of the Equipment is defective
          (reasonable wear and tear resulting solely from proper use excepted)
          or does not operate within the supplier's or manufacturer's
          specifications, Lessee will make repairs or replace all defects with
          supplier or manufacturer approved parts; and after corrective
          measures are completed, Lessee will arrange for a follow-up

          (4) At least 30 days before the end of the Lease Term, provide for an
          inspection and Fair Market Value appraisal to be performed by an
          appraiser selected by Lessor (and, if no Event of Default is
          continuing, reasonably acceptable to Lessee) and send the results of
          the inspection and appraisal to Lessor.

          (5) Return each item of Equipment with an in-depth field service
          report detailing the inspection outlined in subparagraph 3 above. The
          report will certify that the Equipment has been properly inspected,
          examined, and tested and that it operates within the supplier's and
          manufacturer's specifications.

          (6) Return the equipment with a certificate from the manufacturer that
          the Equipment (including any software): i) has been tested and is
          functioning properly; has an operating system at the current level;
          and ii) is qualified for manufacturer maintenance at standard rates
          without any reconditioning, initial set-up, or license charges. If
          Lessee does not provide the certificate, Lessor has the right to have
          the Equipment tested, and Lessee will promptly pay for the cost of:
          i) such testing; ii) any parts, shipping materials, or repairs
          necessary to bring the Equipment to its original performance
          condition (ordinary wear and tear resulting solely from proper use
          excepted); and iii) any updates necessary to bring the operating
          system to current level.

          (7) Ensure that all inspections, overhauls, rebuilding, or
          certifications known to be or expected to be due within 12 months are
          completed prior to return.

          (8) Disassemble and pack the Equipment according to the supplier's
          and manufacturer's specifications and recommendations, to include the
          following: (i) remove all process fluids from the Equipment and
          dispose of them in accordance with then-current waste disposal laws
          and regulations (at no time are materials which could be considered
          hazardous waste by any regulatory authority to be shipped with the
          Equipment); and (ii) fill all internal fluids (such as lube oil and
          hydraulic fluid) to operating levels and secure filler caps and seal
          all disconnect hoses to avoid spillage.

          (9) Within 10 days of the end of the Lease Term, transport the
          Equipment to not more than ten individual locations in the
          continental United States selected by Lessor, and provide the
          insurance required by Paragraph 6 of the Agreement prior to and
          during transport of the Equipment.

          (10) If requested by Lessor, provide insurance and safe, secure
          storage for the Equipment for 90 days after the end of the Lease
          Term.

(e) Failure to Return. In addition to Lessor's other remedies in Paragraph 14 of
the Agreement, if Lessee fails to return the Equipment within the required time
period or fails to restore the Equipment to the proper condition specified in
subparagraph (b) above, Lessee will

                                                                    /s/  Lessor

continue to pay Rent at the last prevailing rate for the period of delay in
returning the Equipment or for the period of time reasonably necessary for
Lessor (at Lessee's expense) to restore the Equipment to its proper condition.
Lessor's acceptance of this continuing Rent does not constitute a renewal of
the Lease or a waiver of Lessor's right to prompt return of the Equipment in
proper condition.

(g)  Equipment: as identified in the Purchase Agreement.

(h)  Acceptance of the Equipment: means that the Lessee represents and warrants
that the Equipment: (i) has been delivered to and is in the possession of
Lessee; (ii) has been fully inspected by Lessee or its qualified agent; (iii)
is suitable for the purpose intended by Lessee; (iv) is in good order,

accepts the assignment; provided that, other than Lessor's obligation to pay
the purchase price for the Equipment in accordance with Paragraph 3 below,

                                     - 2 -

perform all duties of the "purchaser" under the Purchase Agreement as if this

name to demand and accept the service on the Equipment that the Vendor is
obligated to provide under the Purchase Agreement.

3.   ACCEPTANCE OF EQUIPMENT; PAYMENT; TITLE.

     (a) Lessee will immediately inspect the Equipment upon delivery to ensure
conformance with Vendor's obligations under the Purchase Agreement. According
to the Lease, title to the Equipment will vest in Lessor upon Lessee's
Acceptance of the Equipment, and at that time Lessor will pay Vendor the

payments of the purchase price to Vendor, Lessor will reimburse Lessee for the
partial payments and pay to Vendor the balance of the purchase price, up to the
Total Equipment Cost specified in the Lease.)

     (b) Lessor's obligation to purchase and pay for the Equipment is
conditioned on Lessee's compliance with the Lease. If Lessee does not comply to
Lessor's satisfaction, Lessor's obligation to purchase the Equipment will

fully in effect and is enforceable in accordance with its terms, a true and
complete execution copy of which Lessee has delivered to Lessor; (ii) the

to Lessor; and (v) it will defend Lessor's title to the Equipment against any

agreements of any nature between Vendor and Lessee) have been assigned to or in
any manner assumed by Lessor.

     (c) Vendor agrees that, on Acceptance of the Equipment and payment of the

               made"); and

               (iii) an invoice for each item of Equipment, reflecting Lessor
               as purchaser, in an amount equal to the purchase price of the
