                                  RISK FACTORS

  THE STATEMENTS INCLUDED IN THIS REPORT REGARDING FUTURE FINANCIAL PERFORMANCE
AND RESULTS AND THE OTHER STATEMENTS THAT ARE NOT HISTORICAL FACTS ARE
FORWARD-LOOKING STATEMENTS. THE WORDS "EXPECT," "PROJECT," "ESTIMATE," "PREDICT"
AND SIMILAR EXPRESSIONS ALSO ARE INTENDED TO IDENTIFY FORWARD-LOOKING
STATEMENTS. SUCH STATEMENTS INVOLVE RISKS, UNCERTAINTIES AND ASSUMPTIONS,
INCLUDING BUT NOT LIMITED TO, INDUSTRY CONDITIONS, PRICES OF CRUDE OIL AND
NATURAL GAS, AND OTHER FACTORS DISCUSSED IN THIS REPORT (INCLUDING THOSE
SPECIFICALLY DISCUSSED BELOW) AND IN THE COMPANY'S OTHER FILINGS WITH THE
SECURITIES AND EXCHANGE COMMISSION. SHOULD ONE OR MORE OF THESE RISKS OR
UNCERTAINTIES MATERIALIZE, OR SHOULD UNDERLYING ASSUMPTIONS PROVE INCORRECT,
ACTUAL OUTCOMES MAY VARY MATERIALLY FROM THOSE INDICATED.

  CAPITALIZED TERMS USED IN RISK FACTORS ARE DEFINED LATER IN THIS REPORT.

INCURRENCE OF SUBSTANTIAL INDEBTEDNESS

  At March 31, 1997, the Company had approximately $144.0 million in total
indebtedness. The Company historically has operated at substantially lower
levels of debt. The Company's level of indebtedness has several important
effects on its future operations, including, without limitation, (i) a
substantial portion of the Company's cash flow from operations must be dedicated
to the payment of interest and principal on its indebtedness, (ii) the Company's
leveraged position substantially increases its vulnerability to adverse changes
in general economic and industry conditions, as well as to competitive pressure,
and (iii) the Company's ability to obtain additional financing for working
capital, capital expenditures, acquisitions, general corporate and other
purposes may be limited. The Company's ability to meet its debt service
obligations and to reduce its total indebtedness will be dependent upon the
Company's future performance, which will be subject to general economic
conditions, industry cycles and financial, business and other factors affecting
the operations of the Company, many of which are beyond its control. There can
be no assurance that the Company's business will continue to generate cash flow
at or above current levels. If the Company is unable to generate sufficient cash
flow from operations in the future to service its debt, it may be required,
among other things, to seek additional financing in the debt or equity markets,
to refinance or restructure all or a portion of its indebtedness, including the
Senior Notes, or to sell selected assets or reduce or delay planned capital
expenditures. There can be no assurance that any such measures would be
sufficient to enable the Company to service its debt or that any such financing,
refinancing or sale of assets would be available on economically favorable
terms. See "Business - Senior Notes; Subsidiary Guarantees."

                                        1
<PAGE>
DEPENDENCE ON VOLATILE OIL AND GAS INDUSTRY

  Demand for the Company's services depends substantially upon the level of
activity in the oil and gas industry, which in turn depends in part on oil and
gas prices, expectations about future prices, the cost of exploring for,
producing and delivering oil and gas, the discovery rate of new oil and gas
reserves in land areas, the level of drilling and workover activity, domestic
and international political, military, regulatory and economic conditions and
the ability of oil and gas companies to raise capital. Prices for oil and gas
historically have been extremely volatile and have reacted to changes in the
supply of and demand for oil and natural gas, domestic and worldwide economic
conditions and political instability in oil producing countries. No assurance
can be given that current levels of oil and gas activities will be maintained or
that demand for the Company's services will reflect the level of such
activities. Prices for oil and natural gas are expected to continue to be
volatile and affect the demand for and pricing of the Company's services. A
material decline in oil or natural gas prices or activities could materially
adversely affect the demand for the Company's services and the Company's results
of operations. Industry conditions will continue to be influenced by numerous
factors over which the Company has no control. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business -
Customers."

  The volatility of the oil and gas industry and the consequent impact thereof
on exploration activity could adversely impact certain of the Company's
customers. The Company, therefore, could be subject to special credit risks as
to certain of its customers. While the Company endeavors not to take unjustified
credit risks, it is necessary from time to time to extend trade credit to
long-term customers and others where some risks of nonpayment or late payment
could exist.

ACQUISITION RISKS

  The Company completed the Pride Acquisition in February 1997 and the Taylor
Acquisition in July 1996. Pursuant to the Pride Acquisition the Company acquired
407 workover rigs, which is more than four times the number of workover rigs it
previously operated. No assurance can be given that the Company will be
successful in managing and incorporating the businesses and assets acquired in
the Pride Acquisition or the Taylor Acquisition into its existing operations or
that such activities will not require a disproportionate amount of management's
attention. The Company's failure to incorporate the acquired businesses and
assets into its existing operations successfully, or the occurrence of
unexpected costs or liabilities in the acquired businesses, could have a
material adverse effect on the Company. See "Business - General; -- Business
Strategy."

                                       2
<PAGE>
LIQUIDITY NEEDS; ABILITY TO REPAY NOTES

  The Company may from time to time fund a portion of its working capital needs
and capital expenditure requirements from external financing. In addition, the
Company expects that in order to repay the principal amount of the Senior Notes
at maturity or upon acceleration, or to purchase the Senior Notes upon a Change
of Control, it will likely be required to seek additional financing or engage in
asset sales or similar transactions. There can be no assurance that sufficient
funds for any of the foregoing purposes would be available to the Company at the
time they are required on favorable terms. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources" and "Business - Senior Notes; Subsidiary Guarantees."

RISKS RELATING TO INJECTION WELLS

  The Company's injection operations pose certain risks of environmental
liability to the Company. Although the Company monitors the injection process,
any leakage from the subsurface portions of the wells could cause degradation of
fresh groundwater resources, potentially resulting in cancellation of operation
of the well, fines and penalties from governmental agencies, expenditures for
redemption of the affected resource, and liability to third parties for property
damages and personal injuries. In addition, the sale by the Company of residual
crude oil collected as part of the saltwater injection process could impose
liability on the Company in the event the entity to which the oil was
transferred fails to manage the material in accordance with applicable
environmental health and safety laws.

SUBSTANTIAL COMPETITION

  The workover rig and production services industry is highly competitive and
fragmented and includes several large companies and a number of small companies
capable of competing effectively on a local basis. See "Business - Competition."

OPERATING RISKS AND INSURANCE

  The Company's operations are subject to hazards inherent in the oil and gas
industry, such as blowouts, explosions, craterings, fires and oil spills, that
can cause personal injury or loss of life, damage to or destruction of property,
equipment, the environment and marine life and suspension of operations. In
addition, claims for loss of oil and gas production and damage to formations can
occur in the workover business. Litigation arising from a catastrophic
occurrence at a location where the Company's equipment and services are used may
in the future result in the Company being named as a defendant in lawsuits
asserting potentially large claims.

                                       3
<PAGE>
  The Company maintains insurance coverage that it believes to be customary in
the industry against these hazards. However, there can be no assurance that the
Company will be able to maintain adequate insurance in the future at rates it
considers reasonable or that insurance will continue to be available on terms as
favorable as the Company's existing arrangements. The occurrence of a
significant event or adverse claim in excess of the insurance coverage limits
maintained by the Company could have a materially adverse effect on the
Company's financial condition and results of operations. See "Business -
Operating Risks and Insurance."

RISK OF ENVIRONMENTAL COSTS AND LIABILITIES

  The Company's operations are subject to governmental laws and regulations
governing the management and disposal of waste materials or otherwise relating
to the protection of the environment or of public health and safety. Many of the
Company's operations take place in or near ecologically sensitive areas, such as
the Texas Gulf Coast and Louisiana inland waters. Numerous local, state and
federal environmental laws impose liability for causing pollution in inland and
coastal waters. State and federal legislation also provide special protection to
water quality and animal and marine life that could be affected by some of the
Company's activities. The Company's operations also take place in states that
stringently regulate environmental matters, such as California. In general, the
regulations applicable to the Company's operations include certain regulations
controlling the discharge of hazardous or toxic materials into the environment,
requiring removal or remediation of pollutants and imposing civil and criminal
penalties for violations. Some of the statutory and regulatory programs that
apply to the Company's operations also authorize private suits, the recovery of
nature resource damages by the government, injunctive relief and cease and
desist orders.

  Some environmental statutes impose strict liability, rendering a person or
entity liable for environmental damage without regard to negligence or fault on
the part of such person or entity. As a result, the Company could be liable,
under certain circumstances, for environmental damage caused by others or for
acts of the Company that were in compliance with all applicable laws at the time
such acts were performed.

  The clear trend in environmental regulation has been to impose more
restrictions and limitations on activities that may impact the environment,
including the generation and disposal of wastes and the use and handling of
chemical substances. These restrictions and limitations have increased operating
costs for both the Company and its customers. Any regulatory changes that impose
additional environmental regulations or requirements on the Company and its
customers could adversely affect the Company through increased operating costs
and potential decreased demand for the Company's services.

                                       4
<PAGE>
  In this regard, the Resource Conservation and Recovery Act ("RCRA"), the
principal federal statute governing the disposal of solid and hazardous wastes,
includes a statutory exemption that allows oil and gas exploration and
production wastes to be classified as non-hazardous waste. A similar exemption
is contained in many of the state counterparts to RCRA, including the state
statutes in Texas, New Mexico, and Louisiana however, there is no such exemption
in the California statutes. If oil and gas exploration and production wastes
were required to be managed and disposed of as hazardous waste, either as a
result of changes in RCRA or the imposition of more stringent state regulations,
domestic oil and gas producers, including many of the Company's customers, could
be required to incur substantial obligations with respect to such waste. Because
of the potential impact on the Company's customers, any regulatory changes that
impose additional restrictions or requirements on the disposal of oil and gas
wastes could adversely affect demand for the Company's services. See "Business
Environmental Regulation."

DEPENDENCE ON KEY PERSONNEL

  The Company believes that its success will depend to a significant extent upon
the continued services of certain key individuals, particularly Michael E.
Little, Chairman of the Board, President and Chief Executive Officer, and James
J. Byerlotzer, Vice President of Operations and Chief Operating Officer. The
loss of the services of either of these individuals could have a material
adverse effect on the Company.

DEPENDENCE ON MAJOR CUSTOMERS

  During the fiscal year ended March 31, 1997, the Company derived approximately
20.00% of its revenues from its largest customer. The loss of this customer
could have a material adverse effect on the Company's financial condition and
results of operations. See "Business Customers."

DIVIDEND POLICY

  The Company has never paid cash dividends on the Common Stock and does not
anticipate that cash dividends will be paid in the foreseeable future. The
Company currently intends to retain any future earnings to finance the expansion
and continuing development of the Company's business. The declaration and
payment in the future of any cash dividends will be at the election of the
Company's Board of Directors and will depend upon the earnings, capital
requirements and financial position of the Company, future loan covenants,
general economic conditions and other pertinent factors. Furthermore, certain
provisions of the Credit Facility and the Indenture will restrict the Company's
ability to pay cash dividends on the Common Stock. See "Management's Discussions
and Analysis of Financial Condition and Results of Operations - Liquidity and
Capital Resources."

                                       5

SUBSTANTIAL AMOUNT OF SECURITIES SUBJECT TO REGISTRATION RIGHTS

  Pursuant to a registration rights agreement (the "Registration Rights
Agreement"), shareholders (the "Rights Holders") that beneficially own
approximately 2.4 million shares of Common Stock, or approximately 22% of the
currently issued and outstanding shares of Common Stock, are entitled to
registration of such shares under the Securities Act of 1933, as amended (the
"Securities Act"), subject to certain exceptions and limitations. Under the
Registration Rights Agreement, the Company is obligated to file a registration
statement (the "Shelf Registration Statement"), beginning July 20, 1997 for the
Registrable Securities. The holders of a majority of the Registrable Securities
can require that the Shelf Registration Statement be in the form of an
underwritten offering. Additionally, if the Company proposes to register any of
its securities under the Securities Act for its own account or for the account
of the other security holders, the Rights Holders are entitled to notice of such
registration and are entitled to include all or a portion of the Registrable
Securities in such registration, subject to certain exceptions and limitations,
including the right of the underwriters (if any) of any such offering to exclude
for marketing reasons some or all of the Registrable Securities from such
registration. The Company generally is required to pay all of the expenses
relating to the registration of the Registrable Securities, except for the
Rights Holders' share of any underwriting discounts and commissions. The
Registration Rights Agreement prohibits the Company from granting any new
registration rights under the Securities Act that would adversely impact the
rights of the Rights Holders. Sales of substantial amounts of the Common Stock
in the public market could adversely affect prevailing market prices and the
ability of the Company to raise equity capital in the future.

ANTI-TAKEOVER EFFECT OF CERTAIN PROVISIONS

  The Company's Articles of Incorporation and Bylaws include certain provisions
that may have the effect of discouraging potential unsolicited offers or other
efforts to obtain control of the Company that are not approved by the Board.
Upon a change of control of the Company, holders of the Senior Notes will have
the right to require the Company to purchase such Senior Notes at a price equal
to 101% of the aggregate principal amount thereof, together with accrued and
unpaid interest to the date of purchase. Such provisions may adversely affect
the market price of the Common Stock and may also deprive the shareholders of
opportunities to sell shares of Common Stock at prices higher than prevailing
market prices. Such provisions include the requirement that all shareholder
action must be taken at a duly called annual or special meeting of shareholders
unless a majority of the entire Board provides its prior approval for
shareholder action to be taken by written consent of shareholders. The Board has
the authority, without further action by the shareholders, to issue up to
560,600 shares of the Company's preferred stock in one or more series and to fix

ITEM I.   BUSINESS

GENERAL

  Dawson Production Services, Inc. (the "Company" or "Dawson") is a leading
provider of a broad range of workover, liquid and production services used in
the production of oil and gas. The Company's services are utilized by major oil
and gas companies as well as independent producers to optimize performance of
oil and gas wells. The Company recently acquired the U.S. land-based well
servicing operations of Pride Petroleum Services, Inc. ("Pride") in a
transaction (the "Pride Acquisition") that has positioned Dawson as the second
largest provider of workover rigs in the United States.

  The Company commenced operations in 1951. In 1982, the current management team
joined the Company and initiated a strategy to expand and diversify the
Company's workover rig services. At that time, the Company owned four workover
rigs that were operated out of a single yard. In November 1994, the Company
broadened the array of services that it provides by acquiring the liquid
services and production services businesses of Well Solutions, Inc. (the "Well
Solutions Acquisition") and expanded such business in July 1996 with the
acquisition of Taylor Companies, Inc. (the "Taylor Acquisition"). Subsequent to
the Pride Acquisition that closed effective February 20, 1997, the Company owns
and operates 498 workover rigs. The Company believes that it generally has been
successful in acquiring businesses and assets and subsequently reducing
overhead, enhancing internal controls, improving marketing and related
operations through management incentives and improving the utilization of its
assets by redeploying equipment.

  As a result of its acquisitions and certain corporate restructuring, the
Company currently has several direct and indirect subsidiaries through which it
conducts a significant portion of its operations. All of the assets acquired
from Pride are held in Dawson Production Partners, L.P., a Delaware limited
partnership (the "Partnership"), and the Company is in the process of
transferring substantially all of its remaining operating assets to the
Partnership. All of the general and limited partnership interests in the
Partnership are owned by two wholly owned corporate subsidiaries of Dawson;
Dawson Production Management, Inc., a Delaware corporation, owns a 1% general
partnership interest in the Partnership, and Dawson Production Acquisition
Corp., a Delaware corporation, owns the remaining 99% limited partnership
interest in the Partnership. Dawson has the following additional wholly owned
subsidiaries: Dawson Production Services de Mexico, S.A. de C.V., and Ubicadora
de Tecnicos S.A. de C.V., both of which are companies organized under the laws
of Mexico, Taylor Companies, Inc., a Texas corporation; and Mobley Vehicle
Acquisition Corp., a Texas corporation.

BUSINESS STRATEGY

  The Company's strategy emphasizes diversification and expansion through
acquisitions and internal growth. In recent years, there has been significant
industry consolidation activity in the Company's principal businesses. The
Company has been an active participant in this industry consolidation and plans
to continue to pursue strategic acquisitions of businesses and assets which
enhance or expand its market presence or complement its existing businesses. As
a result of the Pride Acquisition, the Company has expanded the range of
services offered at its locations and continues to increase its presence,
through redeployment of underutilized assets, within the geographic regions in
which the Company operates. The Company believes that its ability to offer a
wide range of services over a large operating base will provide it with a
competitive advantage by allowing its customers to consolidate their procurement
of workover, liquid and production services by utilizing fewer vendors. The
Company believes that this consolidation may allow customers to lower their
costs by streamlining production decisions and increasing operational
efficiencies. The Company also believes that its strategy will allow it to take
advantage of cross-marketing opportunities for its services and to appeal to a
broader customer base by enhancing its position as a one-stop source for
workover, liquid and production services.

  Consistent with its business strategy, on February 20, 1997 the Company closed
a transaction in which it acquired substantially all of Pride's U.S. land-based
well servicing operations for approximately $135.4 million in cash. The Pride
Acquisition has significantly increased the size and geographic scope of the
Company's workover rig service business. This U.S. land-based fleet consists of
407 workover rigs and related operations in 28 locations in the Texas and
Louisiana Gulf Coasts, the Permian Basin areas of West Texas and New Mexico, and
California. The Company is currently the largest provider of workover rigs in
Texas and the second largest provider in the United States. The Company will
seek to generate improved profit margins for the acquired assets through
increased operating efficiencies and cost savings resulting from overhead
reductions and the consolidation of certain overlapping yard locations. In
addition, the Company will seek to expand its liquid and production services
businesses into new markets through certain of the acquired yard locations and
also to redeploy certain of the acquired workover rigs to areas with greater rig
demand.

  The Company believes that the high quality of its equipment, employees and
services combined with its favorable safety record enables it to maintain its
position as a leader in its principal markets. In that regard, the Company has
committed substantial capital to an ongoing workover rig refurbishment program
to maintain the Company's equipment in good working condition. The Company has
invested, and plans to continue to invest, in quality management and safety
programs. The Company believes that many smaller competitors have not undertaken
comparable maintenance or training programs and do not have the financial
resources to enable them to do so. The Company believes that a number of its
customers place significant importance on their contractors' safety records and
quality management systems in their screening and selection processes, and that
such factors will gain further importance in the future.

OVERVIEW OF SERVICES

WORKOVER RIG SERVICES

  The Company provides workover rig services to oil and gas exploration and
production companies through the use of mobile well servicing workover rigs
together with crews of three to four workers. Additional equipment such as
pumps, tanks, blowout preventers and power swivels are provided by the Company
as may be required for a particular job. The Company also provides trucking
services for moving large equipment to and from the job sites of its customers.
The Company charges its customers an hourly rate for its workover rig services,
which varies based on a number of considerations including market conditions in
each region, the type of rig, the amount of ancillary equipment required and the
necessary personnel. The Company gives its yard managers considerable
flexibility to negotiate with customers and, through compensation arrangements,
seeks to provide incentives to its managers to maximize both revenues and
profitability. For the fiscal year ended March 31, 1997, workover rig services
contributed approximately 49% of the Company's revenues.

  The Company operates 496 land workover rigs, two barge-mounted workover rigs
and ancillary equipment from yards in Texas, Louisiana, California and New
Mexico. The Company's land workover rigs are mobile units that generally operate
within a radius of approximately 75 to 100 miles from their respective bases.
Swab rigs are used for swabbing or cleaning wells at depths of up to
approximately 16,000 feet. Pole rigs are used for swabbing and rod and tubing
workovers and repairs on wells at depths of up to approximately 4,000 feet. Rigs
having between 150 and 250 horsepower are used for services on wells to maximum
depths of between 4,000 and 6,000 feet and work primarily on rod and tubing
workovers and repairs. Rigs having between 251 and 350 horsepower are used for
services on wells to maximum depths of between 10,000 and 12,000 feet and also
work primarily on rod and tubing workovers and repairs. Rigs having between 351
and 550 horsepower are used for deeper workovers and more complicated procedures
such as deepening of existing well bores, recompletions and complicated fishing
operations. These rigs operate at maximum depths of between 16,000 and 18,000
feet. Rigs having between 551 and 750 horsepower are used in wells with maximum
depths of approximately 20,000 feet. Rigs having between 751 and 900 horsepower
are generally used for horizontal drilling or recompletion jobs and deep
workovers at depths of up to approximately 25,000 feet. These rigs are almost
always operated for continuous 24-hour periods as contrasted to the Company's
other rigs that typically operate during daylight hours only.

  The Company operates two barge-mounted workover rigs in the Louisiana inland
waters. These rigs typically are outfitted by moving a land workover rig onto
the barge, with operating crews housed on the barge, and have the capability to
operate for continuous 24-hour periods. In addition to hourly charges for the
workover rigs, when market conditions permit, the Company charges its customers
for auxiliary equipment, travel time, mobilization and other related items.

  The Company operated approximately 82 of 89 rigs during the 1996 calendar
year. The Company acquired 407 additional rigs from Pride in February 1997. In
the Pride Purchase Agreement, Pride represented that it had operated 318 of the
approximately 407 rigs within the 12 months ended December 23, 1996. The Company
believes that market demand may justify the incremental cost of refurbishing a
majority of the remaining 89 rigs acquired from Pride and anticipates that a
minority of the 89 rigs may not be restored to operating condition. Therefore,
the Company's stacked rigs will be refurbished, used for spare parts or
liquidated.

  Workover rig services are categorized by the type of job performed:
completion, maintenance, workover, and plugging and abandonment.

  COMPLETION SERVICES. Completion services prepare a newly drilled well for
production. The completion process may involve selectively perforating the well
casing to access producing zones, stimulating and testing these zones and
installing downhole equipment. The Company provides a workover rig to assist in
this completion process. Newly drilled wells are frequently completed by well
servicing rigs to minimize the use of higher cost drilling rigs. The completion
process typically requires a few days to several weeks, depending on the nature
and type of the completion, and generally requires additional auxiliary
equipment.

  The demand for well completion services is directly related to drilling
activity levels, which are sensitive to expectations relating to and changes in
oil and gas prices. During periods of weak drilling demand, drilling contractors
frequently price well completion work competitively compared to a workover rig
so that the drilling rig stays on the job. Thus, excess drilling capacity will
serve to reduce the amount of completion work available to the well servicing
industry.

                                       11
<PAGE>
  MAINTENANCE SERVICES. Maintenance services are required on producing oil and
gas wells to ensure efficient and continuous operation. These services consist
of routine mechanical repairs necessary to maintain production from the well,
such as repairing parted sucker rods or defective downhole pumps in an oil well
or replacing defective tubing in a gas well. The Company provides the workover
rigs, equipment and crews for these maintenance services. Many of these workover
rigs also have pumps and tanks that can be used for circulating fluids into and
out of the well. Maintenance jobs are often performed on a series of wells in
proximity to each other and typically take less than 48 hours per well.

  Maintenance services are generally required throughout the life of a well. The
need for these services does not depend on the level of drilling activity and is
generally independent of short-term fluctuations in oil and gas prices.
Accordingly, maintenance services are generally the most stable type of workover
rig services activity. The general level of maintenance, however, is affected by
changes in the total number of producing oil and gas wells in the Company's
geographic service area.

  WORKOVER SERVICES. In addition to periodic maintenance, producing oil and gas
wells occasionally require major repairs or modifications called "workovers."
Workover services include extensions of existing wells to drain new formations
either through deepening well bores or through drilling of horizontal laterals.
In less extensive workovers, the Company's rigs are used to drill out plugs and
packers in existing well bores to access previously bypassed productive zones.
The Company's workover rigs are also used to convert producing wells to
injection wells during enhanced recovery operations. Workover services also
include major subsurface repairs such as casing repair or replacement, recovery
of tubing and removal of foreign objects in the well bore. These extensive
workover operations are normally performed by a workover rig with additional
specialized auxiliary equipment, which may include rotary drilling equipment,
mud pumps, mud tanks and blowout preventers, depending upon the particular type
of workover operation. Most of the Company's workover rigs are designed and
equipped to perform complex workover operations. A workover may last from a few
days to several weeks.

  The demand for workover services is more sensitive to expectations relating to
and changes in oil and gas prices than the demand for maintenance services, but
not as sensitive as the demand for completion services. When oil and gas prices
are low, there is little incentive to perform workovers on wells to increase
production and well operators tend to defer workover services. As oil and gas
prices increase, the level of workover activity tends to increase as operators
seek to increase production by enhancing the efficiency of their wells.

  PLUGGING AND ABANDONMENT SERVICES. Workover rigs are also used in the plugging
and abandonment of oil and gas wells no longer capable of producing in economic
quantities. The demand for well plugging services is not impacted significantly
by levels of demand for oil and gas.

                                       12

LIQUID SERVICES

  The Company provides liquid services, which are comprised of vacuum truck
services, frac tank rentals and salt water injection services. The Company uses
its vacuum trucks, frac tanks and salt water injection wells to provide an
integrated mix of liquid services to well site customers. For the fiscal year
ended March 31, 1997, liquid services contributed approximately 36% of the
Company's revenues.

  VACUUM TRUCK SERVICES. The Company previously owned and operated 175 vacuum
trucks and it acquired an additional 10 vacuum trucks in connection with the
Pride Acquisition. A vacuum truck is a tractor trailer with a fluid hauling
capacity of 130 barrels. A large vacuum pump mounted on each truck extracts
fluids from pits, tanks and other storage facilities. The vacuum trucks also are
used for the following purposes: to transport water to fill frac tanks on well
locations, including frac tanks provided by the Company and by others; to
transport produced salt water to injection wells, including injection wells
owned and operated by the Company; and to transport brine and other drilling
fluids to and from well locations. In conjunction with the rental of its frac
tanks, the Company generally uses its vacuum trucks to transport water for use
in fracturing operations. Following completion of fracturing operations, the
Company's vacuum trucks are used to transport salt water produced as a result of
the fracturing operations from the well site to injection wells. Vacuum truck
services are generally provided to oilfield operators within a 30-mile radius of
the Company's nearest yard.

  FRAC TANK RENTALS. The Company owns 696 frac tanks located primarily at the
Company's yards in Bryan, Giddings and Kilgore, Texas. Each frac tank can store
up to 500 barrels of fluid and is used by oilfield operators to store various
fluids at the well site, including water, drilling mud, acid and brine. The
Company transports frac tanks on its trucks to well locations which are usually
within a 30-mile radius of the Company's nearest yard. Frac tanks are used
during all phases of the life of a producing well. The Company generally rents
frac tanks at daily rates for a minimum of four days. A typical fracturing
operation, absent complications, can be completed within four days using 20 to
100 frac tanks.

  INJECTION WELL SERVICES. The Company owns or leases 22 injection wells that
are authorized to dispose of salt water and incidental non-hazardous oil and gas
wastes, each with an injection capacity of 2,000 to 21,000 barrels per day. The
Company's injection wells are strategically located in close proximity to its
customers' producing wells. These wells are utilized primarily to dispose of
salt water produced from oil and gas wells. Most oil and gas wells ultimately
produce varying amounts of salt water and, particularly in vertically fractured
formations such as those common in the Austin Chalk trend, produce salt water at
increasing rates throughout their productive lives. In addition, these wells are
utilized for the disposal of incidental, non-hazardous oil and gas wastes. In
Texas and Arkansas, oil and gas wastes and salt water produced from oil and gas
wells are required by law to be disposed of in authorized facilities, including
permitted injection wells. Injection wells are licensed by state authorities and
are completed in permeable formations below the fresh water table.

                                       13
<PAGE>
  The Company utilizes its injection wells primarily for the disposal of salt
water and incidental, non-hazardous oil and gas waste transported from the well
site by vacuum trucks owned and operated by the Company. Although the Company is
authorized to inject salt water and non-hazardous oil and gas wastes transported
by other licensed vacuum truck operators, the Company does not currently permit
such uses by third parties. The Company also maintains separators at each of its
injection wells permitting it to salvage residual crude oil, which is later sold
for the account of the Company.

  The Company's injection operations pose certain risks of environmental
liability to the Company. Although the Company monitors the injection process,
any leakage from the subsurface portions of the wells could cause degradation of
fresh groundwater resources, potentially resulting in cancellation of operation
of the well, fines and penalties from governmental agencies, expenditures for
remediation of the affected resource, and liability to third parties for
property damages and personal injuries. In addition, the sale by the Company of
residual crude oil collected as part of the saltwater injection process could
impose liability on the Company in the event the entity to which the oil was
transferred fails to manage the material in accordance with applicable
environmental health and safety laws.

PRODUCTION SERVICES

  The Company provides production services, which are comprised of production
testing services, slickline wireline services, fishing and rental tool services
and pipe testing. For the fiscal year ended March 31, 1997, production services
contributed approximately 15% of the Company's revenues.

  PRODUCTION TESTING SERVICES. The Company owns 21 gas production testing units
that are used to provide services to oil and gas wells located onshore and in
inland waters. The Company performs production testing services for oil and gas
producers primarily along the Texas Gulf Coast and to a limited extent in
Mexico. In addition, the Company is bidding on a multi-year contract for
services in northern Mexico.

  The Company's equipment includes several trailer-mounted manifolds,
separators, heater treaters, sand separators, light generators and slickline
wireline units. Manifolds are used to reduce the flowing pressure of the well
stream to a rate which will easily flow through the production testing
equipment. After the appropriate well stream rate is achieved, a separator is
used to divide the well stream into its respective components -- oil, gas and
water. For gas wells, a heater is used to prevent the gas from freezing during
flowbacks. Slickline wireline equipment generally is used to lower measurement
equipment into a well for several days to retrieve data to determine the
characteristics of the reservoir.

                                       14
<PAGE>
  The Company uses its production testing units to perform deliverability tests
required upon the initial completion of a well and periodically during the
productive life of a gas well to determine the maximum production allowable
under certain rules of the Texas Railroad Commission, the state oil and gas
regulatory agency. In addition, these units are used to clean and test
stimulated wells and to measure the pressure, volume and quality of gas and
liquids produced by the well. These units also are used to determine the most
efficient production flow rate, to run pressure build-up tests that measure the
rate of increase of shut-in gas pressure to determine reservoir characteristics
and to determine whether a producing formation has been damaged.

  SLICKLINE WIRELINE SERVICES. The Company owns seven slickline wireline units
and will acquire three additional units upon the closing of the Pride
Acquisition. The mechanical downhole wireline or "slickline" services are used
to simplify completion operations and in connection with regular maintenance on
producing wells. In some cases, slickline wireline services may be used instead
of workover rigs to provide workover services. By using slickline wireline
services, workover services can be performed under 15,000 psi of pressure
without shutting-in the well. The Company also provides slickline wireline
consulting services where unusual conditions exist.

  FISHING AND RENTAL TOOLS. The Company provides a complete line of cased hole
fishing and rental tools to oilfield operators and well service companies from
two yards in the Texas Panhandle. The Company's rental tool inventory includes
both air compressor equipment, which is used in drilling and workover
activities, and fishing tools, which are used to mill or retrieve loose or
broken equipment or other material in the well bore or to free stuck pipe and
other tools, such as slips, elevators and casing cutters. The Company rents the
equipment to its customers at daily rates and, in the case of air compressors
and fishing tools, generally conducts or supervises the operations.

  PIPE TESTING. The Company operates nine pipe testing units along the Texas
Gulf Coast. The Company's testing equipment is used during completion and
recompletion operations for leak detection in the internal pipe systems of oil
and gas wells.

                                       15
<PAGE>
COMPETITION

  The workover rig and production services industry is highly competitive and
fragmented and includes several large companies and a number of small companies
capable of competing effectively on a local basis. As a result of the Pride
Acquisition, the Company is the second largest provider of workover rigs in the
United States behind Pool Energy Services Co. ("Pool"). Pool and Key Energy
Group, Inc. ("Key") are the largest companies that currently compete with the
Company in providing workover rig and liquid services in the domestic well
servicing markets. Pool and Key operate in multiple geographic regions and Pool
has significantly more domestic workover rigs than the Company. In addition to
these large companies, the Company has numerous regional competitors for each of
the services it provides. The Company believes that it is competitive in terms
of pricing, performance, equipment, safety, availability of equipment to meet
customer needs and availability of experienced, skilled personnel in those areas
in which it operates.

  Excess capacity in the well servicing industry has resulted in severe price
competition throughout much of the past decade. In the well servicing market, an
important competitive factor in establishing and maintaining long-term customer
relationships is having an experienced and skilled work force. In recent years,
many of the Company's larger customers have placed an emphasis not only on
pricing, but also on safety records and quality management systems of
contractors. The Company believes that such factors will gain further importance
in the future. The Company has directed substantial resources toward employee
safety and quality management training programs as well as its employee review
process. While the Company's efforts in these areas are not unique, many
competitors, particularly small contractors, have not undertaken similar
training programs for their employees. The Company expects competition and
pricing pressures to continue in the foreseeable future.

CUSTOMERS

  The Company has approximately 3,700 active customers. The Company's largest
customer, Union Pacific Resources Company ("UPRC"), accounted for approximately
20.00% of the Company's revenues for the fiscal year ended March 31, 1997. The
Company has a contract with UPRC to provide liquid and workover rig services,
which expires in February 1999 (with respect to liquid services) and August 1997
(with respect to workover rig services). The Company is required to maintain
established levels of insurance and to indemnify UPRC against all losses arising
in whole or in part from the Company's negligence, whether or not UPRC and its
agents were contributorily negligent. While the Company believes that its
relationship with UPRC is good, the loss of UPRC, or a significant reduction in
business done with the Company by UPRC, if not offset by sales to new or
existing customers, could have a material adverse effect on the Company's
business, results of operations and prospects. No other customer accounted for
more than 10% of the Company's revenues during the fiscal year ended March 31,
1997.

                                       16
<PAGE>
EMPLOYEES

  As of June 20, 1997, the Company employed approximately 3,051 people, of whom
approximately 2,527 were employed on an hourly basis. The Company's future
success will depend partially on its ability to attract, retain and motivate
qualified personnel. The Company is not a party to any collective bargaining
agreements and has not experienced any strikes or work stoppages. The Company
considers its relations with employees to be generally satisfactory.

OPERATING RISKS AND INSURANCE

  The Company's operations are subject to hazards inherent in the oil and gas
industry, such as blowouts, explosions, craterings, fires and oil spills, that
can cause personal injury or loss of life, damage to or destruction of property,
equipment, the environment and marine life, and suspension of operations. In
addition, claims for loss of oil and gas production and damage to formations can
occur in the workover business. If a serious accident was to occur at a location
where the Company's equipment and services are used, it could result in the
Company being named as a defendant in lawsuits asserting potentially large
claims.

  Because the Company's vacuum truck and frac tank rentals involve the
transportation of heavy equipment and materials, the Company may experience
traffic accidents which may result in spills, property damage and personal
injury. Despite the Company's efforts to maintain high safety standards, the
Company from time to time has suffered losses in the past and anticipates that
it could experience further losses in the future. Moreover, the frequency and
severity of such incidents affect the Company's operating costs and
insurability, and its relationship with customers, employees and regulators. Any
significant increase in the frequency or severity of such incidents, or the
general level of compensation awards with respect thereto, could adversely
affect the cost of, or ability of the Company to obtain, workers' compensation
and other forms of insurance, and could have other material adverse effects on
the Company's financial condition and results of operations.

  As a protection against operating hazards, the Company maintains broad
insurance coverage, including physical damage, employer's liability,
comprehensive commercial general liability and workers' compensation insurance.
The Company believes that it is adequately insured for public liability and
property damage to others with respect to its operations, and that its insurance
coverage is comparable to that which is customary in the industry against such
hazards. However, such insurance may not be sufficient to protect the Company
against liability for all consequences of well disasters, extensive fire damage,
damage to personal property, injuries to or deaths of persons or damage to the
environment. In addition, certain insurance policies exclude coverage for
damages resulting from environmental contamination. The Company also carries
insurance to

                                       17
<PAGE>
cover physical damage to or loss of certain of its workover rigs. No assurance
can be given that the Company will be able to maintain the type and amount of
coverage that it considers adequate at rates that it considers reasonable or
that insurance will continue to be available on terms as favorable as the
Company's existing arrangements.

  In addition to insurance, the Company conducts training programs designed to
promote the safe operation of all equipment and to minimize accidents occurring
on job sites. The Company gives its managers incentives, through compensation
arrangements, to take all reasonable steps possible to promote safety. The
Company monitors safety closely and has carefully designed safety programs to
reduce costs associated with accidents. However, there can be no assurance that
the Company's insurance or safety programs will be adequate to protect against
liability for accidents occurring on the job site or affecting the Company's
equipment.

ENVIRONMENTAL REGULATION

  Many of the Company's operations take place in or near ecologically sensitive
areas, such as the Texas Gulf Coast and the Louisiana inland waters, as well as
in states that stringently regulate environmental matters, such as California.
In addition, the Company's operations routinely involve the handling of
significant amounts of waste materials, some of which are classified as
hazardous substances. The Company's operations and facilities are thus subject
to numerous local, state and federal environmental and public health and safety
laws, rules and regulations, including laws concerning the containment and
disposal of hazardous materials, oilfield waste and other waste materials, the
use of underground storage tanks and the use of underground injection wells. The
regulations applicable to the Company's operations include certain regulations
controlling the discharge of hazardous or toxic materials into the environment,
requiring removal or remediation of pollutants, requiring permits or licenses
issued by regulatory agencies and imposing civil and criminal penalties for
violations. Some of the statutory and regulatory programs that apply to the
Company's operations also authorize private suits, the recovery of natural
resource damages by the government, injunctive relief and cease and desist
orders. Moreover, environmental laws typically expose the Company to "strict
liability" rendering a person or entity liable for environmental damage without
regard to negligence or fault on the part of such person or entity. As a result,
the Company could be liable for cleanup costs, even if the situation resulted
from previous acts by the Company that were lawful at the time or from the
improper conduct of, or conditions caused by, previous property owners, lessees
or other persons not associated with the Company. Environmental laws have become
more stringent in recent years and are expected to become even more so in the
future.

  Cleanup costs associated with environmental claims or capital expenditures or
increased operating costs associated with changes in environmental laws and
regulations could be substantial and could have a material adverse effect on the
Company's financial condition and

                                       18
<PAGE>
results of operations. However, the cost of environmental compliance has not had
any material adverse effect on the Company's operations, financial condition or
competitive position in the past, and management is not currently aware of any
situation or condition that it believes is likely to have any such material
adverse effect or require any material capital expenditure in the foreseeable
future. In addition to management personnel who are responsible for monitoring
environmental compliance and arranging for remedial actions as required from,
the Company also employs from time to time outside experts to advise and assist
the Company's environmental compliance efforts.

  In addition to having a direct effect on the Company, local, state and federal
environmental regulations also may negatively impact oil and gas exploration and
production companies which in turn could have a material adverse effect on the
Company. To the extent laws are enacted or other governmental action is taken
that prohibits or restricts drilling or imposes environmental protection
requirements that result in increased costs to the oil and gas industry in
general and the drilling industry in particular, the financial condition and
results of operations of the Company could be adversely affected.

  In this regard, RCRA, the principal federal statute governing the disposal of
solid and hazardous wastes, includes a statutory exemption that allows oil and
gas exploration and production wastes to be classified as nonhazardous waste. A
similar exemption is contained in many of the state counterparts to RCRA,
including the state statutes in Texas, New Mexico and Louisiana however, there
is no such exemption in the California statutes. If oil and gas exploration and
production wastes were required to be managed and disposed of as hazardous
waste, either as a result of changes in RCRA or the imposition of more stringent
state regulations, the Company could be required to make significant
unanticipated capital and operating expenditures or to cease or curtail certain
operations. Further, if such wastes were required to be managed and disposed of
as hazardous waste, domestic oil and gas producers, including many of the
Company's customers, could be required to incur substantial obligations with
respect to such waste. Because of the potential impact on the Company's
customers, any regulatory changes that impose additional restrictions or
requirements on the disposal of oil and gas wastes could adversely affect demand
for the Company's services.

SENIOR NOTES; SUBSIDIARY GUARANTEES

  Terms used in this subheading as defined terms have the same meanings as set
forth in the Indenture between the Company and its Subsidiary Guarantors, dated
as of February 20, 1997, with U.S. Trust Company of Texas, N.A. as trustee,
relating to the Company's 9 3/8% Senior Notes due 2007. Each of the Company's
Significant Subsidiaries on the Issue Date, including those acquired in the
Pride Acquisition, and each other Restricted Subsidiary that provides a
guarantee under the Credit Facility (defined in the Indenture to include the
Working Line which is in effect, and the Acquisition Line, which is not) became
a Subsidiary Guarantor under

                                       19
<PAGE>
the Indenture. Each Subsidiary Guarantor has unconditionally guaranteed on a
senior basis, jointly and severally, the full and prompt performance of the
Company's obligations under the Indenture and the Notes, including the payment
of principal and interest on the Notes. The obligations of each Subsidiary
Guarantor under its Subsidiary Guarantee is limited to the maximum amount as
will, after giving effect to all other contingent and fixed liabilities of such
Subsidiary Guarantor and after giving effect to any collections from or payments
made by or on behalf of any other Subsidiary Guarantor in respect of the
obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee or
pursuant to its contribution obligations under the Indenture, result in the
obligations of such Subsidiary Guarantor under the Subsidiary Guarantee not
constituting a fraudulent conveyance or fraudulent transfer under federal or
state law. The terms of the Subsidiary Guarantees provide that, for purposes of
such limitations and the applicable fraudulent conveyance laws, any indebtedness
of a Subsidiary Guarantor incurred from time to time pursuant to the Credit
Facility and secured by a perfected Lien on the assets of such Subsidiary
Guarantor (assuming, for purposes of such determination, that the incurrence of
any such indebtedness and the granting of any such security interest did not
violate any such fraudulent conveyance laws) shall be deemed, to the extent of
the value of the assets subject to such Lien, to have been incurred prior to the
incurrence by such Subsidiary Guarantor of liability under its Subsidiary
Guarantee.

  The Indenture provides that no Subsidiary Guarantor may consolidate with or
merge with or into (whether or not such Subsidiary Guarantor is the surviving
Person) another Person (other than the Company or another Subsidiary Guarantor),
whether or not affiliated with such Subsidiary Guarantor, unless (i) subject to
the provisions of the following paragraph, the Person formed by or surviving any
such consolidation or merger (if other than such Subsidiary Guarantor) shall
execute a Subsidiary Guarantee and deliver an opinion of counsel in accordance
with the terms of the Indenture; (ii) immediately after giving effect to such
transaction, no Default or Event of Default exists; (iii) such Subsidiary
Guarantor, or any Person formed by or surviving any such consolidation or
merger, would have Consolidated Net Worth (immediately after giving effect to
such transaction), equal to or greater than the Consolidated Net Worth of such
Subsidiary Guarantor immediately preceding the transaction; (iv) the Company
would be permitted by virtue of the Company's pro forma Fixed Charge Coverage
Ratio, immediately after giving effect to such transaction, to incur at least
$1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in the Indenture; and (v) such transaction does not violate
certain other covenants described in the Indenture.

  The Indenture provides that in the event of (i) the designation of any
Subsidiary Guarantor as an Unrestricted Subsidiary or (ii) a sale or other
disposition of all or substantially all of the property or assets of any
Subsidiary Guarantor to a third party or an Unrestricted Subsidiary, by way of
merger, consolidation or otherwise, or a sale or other disposition of all of the
capital stock of any Subsidiary Guarantor, in either case, in a transaction or
manner that does not violate any of the covenants in the Indenture, then such
Subsidiary Guarantor (in the event of such a designation

                                       20
<PAGE>
or a sale or other disposition, by way of such a merger, consolidation or
otherwise, of all of the capital stock of such Subsidiary Guarantor) or the
Person acquiring the property (in the event of a sale or other disposition of
all or substantially all of the properties or assets of such Subsidiary
Guarantor) will be released from and relieved of any obligations under its
Subsidiary Guarantee, PROVIDED that any Net Proceeds of such sale or other
disposition are applied in accordance with certain covenants set forth in the
Indenture, and PROVIDED, FURTHER, HOWEVER, that any such termination shall occur
only to the extent that all obligations of such Subsidiary Guarantor under all
of its guarantees of, and under all of its pledges of assets or other security
interests that secure, any other Indebtedness of the Company or its Restricted
Subsidiaries shall also terminate upon such release, sale or disposition.

  The Indenture provides that (i) if the Company or any of its Restricted
Subsidiaries shall, after the Issue Date, (a) transfer or cause to be
transferred, any assets, businesses, divisions, real property or equipment
having an aggregate fair market or book value in excess of $1.0 million to any
Restricted Subsidiary that is not a Subsidiary Guarantor or (b) make any
Investment having an aggregate fair market or book value in excess of $1.0
million in any Restricted Subsidiary that is not a Subsidiary Guarantor or (ii)
if, after the Issue Date, any Restricted Subsidiary that is not a Subsidiary
Guarantor shall own any assets or properties having an aggregate fair market or
book value in excess of $1.0 million, then the Company shall cause such
Restricted Subsidiary to execute a Subsidiary Guarantee and deliver an opinion
of counsel, in accordance with the terms of the Indenture. In addition, the
Company shall not permit any of its Restricted Subsidiaries, other than a
Subsidiary Guarantor, directly or indirectly, to (i) incur, guarantee or secure
through the granting of Liens the payment of any Indebtedness of the Company or
(ii) pledge any intercompany notes representing obligations of any of its
Restricted Subsidiaries to secure the payment of any Indebtedness of the
Company, in each case, unless the Company shall cause such Restricted Subsidiary
to execute a Subsidiary Guarantee and deliver an opinion of counsel in advance
in accordance with the terms of the Indenture.

  The Notes are effectively subordinated in right of payment to all existing and
future senior Indebtedness of the Company, which includes any draws made under
the Credit Facility. As of March 31, 1997, the Company's Credit Facility
consisted of a $50.0 million working capital line of credit which, if borrowed,
would be included as senior Indebtedness. The Indenture also permits the Company
to have an acquisition line of credit of up to $10.0 million. See "Management's
Discussion and Analysis - Liquidity and Capital Resources." Thus, the Notes and
the Subsidiary Guarantees are effectively subordinated to claims of the lenders
under the Credit Facility to the extent of such pledged collateral. At March 31,
1997, the Notes and the Subsidiary Guarantees were not subordinated to any
secured Indebtedness (excluding letters of credit) of the Company or the
Subsidiary Guarantors.

  Certain summary financial information concerning Dawson Production Services,
Inc., on an unconsolidated basis, is set forth in the notes to the financial
statements appearing elsewhere in this report. As noted above, the Company is in
the process of completing the transfer of substantially all of its assets to the
Partnership, which is expected to occur during July, 1997. Accordingly, at such
time, substantially all of Company's revenue producing assets (other than
interests in the Partnership itself) will be owned by the Partnership, which is
a Subsidiary Guarantor. The Company's subsidiaries making such transfers are
also Subsidiary Guarantors and the transfers are thus permissible under the
terms of the Indenture.

ITEM 2. PROPERTIES

PROPERTIES

  The principal office of the Company is located in approximately 16,400 square
feet of leased office space in San Antonio, Texas. The Company now operates
approximately 39 yards, 15 of which it owns and 24 of which it leases. Of the
Company's approximately 39 yards, 32 yards are located in Texas, 2 yards are
located in Louisiana, 2 yards are located in New Mexico, and 3 yards are located
in California. The Company has an option to purchase 9 of its leased yards
pursuant to the terms of the Pride Purchase Agreement. The Company also operates
21 injection wells in Texas and 1 in Arkansas, 6 of which it owns and 15 of
which it leases. The Company believes that its leased and owned properties, none
of which individually is material to the Company, are adequate for its current
needs.

ITEM 3. LEGAL PROCEEDINGS

  From time to time, the Company is a party to litigation or other legal
proceedings that the Company considers to be a part of the ordinary course of
its business. The Company currently is not involved in any legal proceedings
that could reasonably be expected to have a material adverse effect on the
Company's financial condition or results of operations. See "Business Operating
Risks and Insurance."

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

  No matters were submitted, during the fourth quarter of the Company's fiscal
year ended March 31, 1997, to a vote of its shareholders.

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED SHAREHOLDER MATTERS

  The Company's Common Stock commenced trading on the Nasdaq National Market on
March 20, 1996 under the symbol "DPSI." The following table sets forth the high
and low sale prices per share of the Common Stock as reported by the Nasdaq
National Market for the periods indicated. 

                                                          HIGH            LOW

       Fourth Quarter (March 20, 1996 - March 31, 1996)  $11 7/8        $10

Fiscal 1997
       First Quarter (April 1 - June 30, 1996)           $14 1/2        $10 3/4
       Second Quarter (July 1 - September 30, 1996)      $14            $ 9 3/4
       Third Quarter (October 1 - December 31, 1996      $16 1/4        $11 1/2
       Fourth Quarter (January 1 - March 31, 1997)       $16 1/2        $11 3/16

  On March 31, 1997, the last reported sale price of the Common Stock on the
Nasdaq National Market was $12 1/4 per share. At June 24, 1997, the Company had
112 shareholders of record of the Common Stock. The Company believes that there
are in excess of 400 beneficial owners of the Common Stock.

  The Company has never paid cash dividends on the Common Stock and does not
anticipate that cash dividends will be paid in the foreseeable future.
Furthermore, certain provisions of the Credit Facility and the Indenture
restrict the Company's ability to pay cash dividends on the Common Stock. Prior
to the conversion of the Company's Series A Preferred Stock into Common Stock in
March 1996, dividends were paid on the Series A Preferred Stock at the rate of
$1.25 per share per annum, in accordance with the requirements of the Company's
Articles of Incorporation. Such dividends were payable, at the option of the
Company, either in cash or in shares of Common Stock, at the rate of one share
of Common Stock for each $3.49 of dividends due. The Company paid dividends on
the Series A Preferred Stock both in cash and in shares of Common Stock. The
Company's loan agreement in effect at the time with its bank prohibited the
payment of dividends; however, the bank waived this provision with respect to
the payment of Series A Preferred Stock dividends. No Series A Preferred Stock
is currently outstanding.

  The Company currently intends to retain any future earnings to finance the
expansion and continuing development of the Company's business. The declaration
and payment in the future of any cash dividends will be at the election of the
Company's Board of Directors and will depend upon the earnings, capital
requirements and financial position of the Company, future loan covenants,
general economic conditions and other pertinent factors. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS

  The following Management's Discussion and Analysis of Financial Condition and
Results of Operations contains forward looking statements which involve risks
and uncertainties. The Company's actual results could differ materially from
those anticipated in these forward looking statements. In addition, the
Management's Discussion and Analysis should be read in conjunction with, and is
qualified in its entirety by reference to, the financial statements of the
Company and the notes thereto included elsewhere in this Annual Report. This
discussion and analysis of operations compares the three fiscal years ended
March 31, 1995, 1996 and 1997.

GENERAL

  The Company's operations have been significantly impacted by the Pride
Acquisition. As a result of the Pride Acquisition, the Company increased its
workover rig fleet to over five times its previous size to become the second
largest provider of workover rigs in the United States. In addition, the Company
has acquired significant operations in California, a market in which it did not
previously operate. The Company also will seek to expand its liquid and
production services into land-based well servicing areas acquired through the
Pride Acquisition. The Company does not have any current understanding,
arrangement or agreement to acquire other businesses or assets. There can be no
assurance that attractive acquisitions will be available to the Company at
prices it believes to be reasonable or that any acquisition achieved will
ultimately prove to be a successful undertaking by the Company. Consistent with
its strategy, the Company intends to continue to pursue acquisitions of
businesses and assets as attractive opportunities become available.

  The Company has experienced revenue growth as a result of the Pride
Acquisition and, to a lesser extent, the Taylor Acquisition. The Company derives
its revenues from workover rig services, liquid services and production
services. Workover rig services are billed at hourly rates that are generally
determined by the type of equipment required, market conditions in the region in
which the rig operates, the ancillary equipment provided on the rig and the
necessary personnel. The Company charges its customers for liquid services
either on an hourly basis or on a per barrel basis depending on the services
offered, while production services are primarily billed on an hourly basis. The
base rates for the Company's services have generally been stable over the past
three years.

                                       26
<PAGE>
  In February 1997, the Company sold 4,722,259 shares of its common stock at
$12.50 per share in a public offering which yielded net proceeds of
approximately $55.3 million. Concurrent with the stock offering, the Company
sold $140 million of senior unsecured notes at par value. The senior unsecured
notes carry a coupon rate of interest of 9 3/8%, the proceeds of which netted
the Company approximately $135.3 million. The total proceeds from the stock and
senior unsecured note offerings (the "Offerings") yielded the Company combined
proceeds of approximately $190.6 million of which $135.4 million was used to pay
the consideration attributable to the Pride Acquisition. Approximately $12.3
million was used to repay existing indebtedness and the remainder is being used
for working capital and general corporate purposes.

  The Company's operating costs are comprised primarily of labor and maintenance
costs. Labor costs generally are variable and are incurred only while a workover
rig is operating or liquid services or production services are being provided;
however, the Company employs rig personnel to perform maintenance and other
services who are paid even when rigs are not operating. The Company's
administrative staff at the yard level and in the corporate office are accounted
for as general and administrative expense. Insurance costs generally are fixed
costs and relate to the number of active rigs, trucks and other equipment in the
Company's fleet. The Company's workers' compensation insurance costs have
declined over the past two years due to its favorable safety record.

RESULTS OF OPERATIONS

YEAR ENDED MARCH 31, 1997 COMPARED TO THE YEAR ENDED MARCH 31, 1996

  REVENUES. Revenues for the year ended March 31, 1997 were $92.6 million, an
increase of 77% from $52.4 million for the year ended March 31, 1996. This
increase in revenues is primarily attributable to the various acquisitions made
during the fiscal year ended March 31, 1997. The Pride Acquisition added 407
workover rigs, the Taylor Acquisition added 66 vacuum trucks to the Company's
fleet, and the acquisition of Mobley Company, Inc. ("the Mobley Acquisition")
added 33 vacuum trucks. Various other acquisitions added 11 vacuum trucks, a
Louisiana production testing company and six workover rigs.

  OPERATING COSTS. Operating costs for the year ended March 31, 1997 were $60.0
million, an increase of 75% from $34.3 million for the year ended March 31,
1996. This increase was due primarily to the Pride and Taylor Acquisitions.
Operating costs as a percentage of revenues remained constant at 65% for the
years ended March 31, 1997 and 1996.

                                       27
<PAGE>
  GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses for
the year ended March 31, 1997 were $14.8 million, an increase of 65% from $8.9
million for the year ended March 31, 1996. This increase was due primarily to
the higher general and administrative expenses associated with the Pride and
Taylor Acquisitions, which significantly increased the Company's fixed cost base
with the addition of 29 new yard locations. As a percentage of revenues, general
and administrative expenses decreased to 16% for the year ended March 31, 1997,
compared to 17% for the prior year.

  DEPRECIATION AND AMORTIZATION. Depreciation and amortization expense for the
year ended March 31, 1997 was $7.8 million, an increase of 78% from $4.4 million
for the year ended March 31, 1996. This increase was due to a substantial
increase in the Company's asset base resulting from the Pride and Taylor
Acquisitions.

  INTEREST EXPENSE. Interest expense for the year ended March 31, 1997 was $2.3
million compared to $1.9 million for the year ended March 31, 1996. The increase
of $.4 million is attributable to two factors. First, interest expense declined
for the first nine months of the year ended March 31, 1997 due to the retirement
of debt from funds generated from the Company's initial public offering
completed in March 1996. Secondly, interest expense in the fourth quarter of
fiscal 1997 increased substantially due to the $140.0 million senior notes
incurred in the Debt Offering in February 1997.

  MINORITY INTEREST. Minority interest for the year ended March 31, 1997 was
$nil, compared to $0.9 million for the year ended March 31, 1996. This decrease
was a result of the Company's acquisition of the Minority interest in Dawson
Welltech L.C. in November of 1996. 

YEAR ENDED MARCH 31, 1996 COMPARED TO THE YEAR ENDED MARCH 31, 1995

  REVENUES. Revenues for the year ended March 31, 1996 were $52.4 million, an
increase of 46% from $36.0 million for the year ended March 31, 1995. This
increase was due primarily to the Well Solutions Acquisition in November 1995.
Revenues from workover rig services were slightly higher for the year ended
March 31, 1996 compared to the prior year due to increased demand for horizontal
recompletion services and the introduction of a second barge-mounted workover
rig in August 1995.

  OPERATING COSTS. Operating costs for the year ended March 31, 1996 were $34.3
million, an increase of 42% from $24.2 million for the year ended March 31,
1995. This increase was due primarily to the Well Solutions Acquisition.
Operating costs as a percentage of revenues decreased to 65% for the year ended
March 31, 1996 compared to 67% for the prior year, which reflects the higher
margin characteristics of the liquid services and production services businesses
acquired in the Well Solutions Acquisition compared to the Company's workover
rig services business.

                                       28
<PAGE>
  GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses for
the year ended March 31, 1996 were $8.9 million, an increase of 60% from $5.6
million for the year ended March 31, 1995. This increase was due primarily to
the higher general and administrative expenses associated with the Well
Solutions Acquisition, which significantly increased the Company's fixed cost
base with the addition of seven new yard locations. As a percentage of revenues,
general and administrative expenses increased to 17% for the year ended March
31, 1996, compared to 15% for the prior year. In fiscal year 1996, the Company
granted bonuses of $336,000 in connection with exercises of non-statutory stock
options by certain of the Company's current and former officers, directors and
employees with regard to federal tax liability they incurred related to such
exercises. The Company does not anticipate granting bonuses for such purposes in
the future.

  DEPRECIATION AND AMORTIZATION. Depreciation and amortization expense for the
year ended March 31, 1996 was $4.4 million, an increase of 69% from $2.6 million
for the year ended March 31, 1995. This increase was due to a substantial
increase in the Company's asset base resulting from the Well Solutions
Acquisition.

  INTEREST EXPENSE. Interest expense for the year ended March 31, 1996 was $1.9
million compared to $0.8 million for the year ended March 31, 1995, due to the
incurrence, in connection with the Well Solutions Acquisition, of $13.0 million
of debt with a 10.81% interest rate. The approximately $11.4 million of debt
remaining in March 1996 relating to the Well Solutions Acquisition was prepaid
with a portion of the proceeds from the IPO.

  MINORITY INTEREST. Minority interest for the year ended March 31, 1996 was
$0.9 million, a decrease of 12% from $1.1 million for the year ended March 31,
1995. This decrease was a result of the acquisition in November 1995 of the
Minority interest in Dawson Welltech, L.C.

  EXTRAORDINARY ITEM. As a result of the prepayment of approximately $11.4
million of debt related to the Well Solutions Acquisition, the Company recorded
an extraordinary expense for the year ended March 31, 1996 amounting to
approximately $0.5 million (net of taxes). This amount represents prepayment
penalties, reimbursement to the lender for its costs and expenses resulting from
the prepayment and the write-off of fees incurred at loan origination (net of
taxes).

LIQUIDITY AND CAPITAL RESOURCES

  The Company had cash and cash equivalents of approximately $42.3 million at
March 31, 1997 compared to approximately $13.9 million at March 31, 1996.
Working capital was approximately $56.0 million and approximately $16.8 million
at March 31, 1997 and March 31, 1996, respectively. The Company used a net
amount of approximately $163.8 million for investing activities during the
fiscal year ended March 31, 1997, primarily for the Pride and Taylor Acquisition
and for other capital expenditures of approximately $63 million. Acquisitions of
additional assets

                                       29
<PAGE>
and businesses are expected to continue to be an important part of the Company's
strategy. Under certain circumstances, the Company would need to obtain
additional financing to fund such acquisitions.

  On January 20, 1997, the Company completed the Mobley Acquisition. The Company
paid approximately $5.0 million of the acquisition price from its existing cash.
The remainder of the purchase price consisted of a $0.5 million five year
subordinated note.

  In February 1997, the Company sold 4,722,259 shares of its common stock at
$12.50 per share in a public offering which yielded net proceeds of
approximately $55.3 million. Concurrent with the stock offering, the Company
sold $140.0 million of senior unsecured notes at par value. The senior unsecured
notes carry a coupon rate of interest of 9 3/8%, the proceeds of which netted
the Company approximately $135.3 million. The total net proceeds from the
Offerings yielded the Company combined proceeds of approximately $190.6 million
of which $135.4 million was used to pay the consideration attributable to the
Pride Acquisition. Approximately $12.3 million was used to repay existing
indebtedness and the remainder is being used for working capital and general
corporate purposes.

  The Company has $3.75 million of subordinated debt outstanding at March 31,
1997. Approximately $1.5 million of the subordinated debt is represented by a
debenture held by Well Solutions, bears interest at 8%, matures on November 30,
1999, is prepayable without penalty at any time, and may be converted at any
time, at the option of the holder, into 37,634 shares of Company Common Stock,
subject to adjustment to prevent dilution. The Company does not currently intend
to prepay the debenture by may decide to do so in the future if interest rates
decline. Approximately $1.75 million of subordinated debt is represented by a
subordinated, non-negotiable promissory note held by PSD Investments, Ltd.,
which bears interest at 8%, matures on July 26, 2001 and is prepayable without
penalty at any time. In addition, approximately $.5 million of subordinated debt
is represented by a promissory note held by The Mobley Company, Inc., which
bears interest at 8.5%, matures on January 20, 2002 and is prepayable without
penalty at any time.

     All of the subordinated debt of the Company was incurred in conjunction
with certain acquisitions made by the Company and have offset provisions in
conjunction with unforeseen liabilities that might arise from these
acquisitions. The Company has received a request for acceleration of payment and
has been served with a lawsuit relating to the $1.75 million of subordinated
debt held by PSD Investments, Ltd. debt due to an alleged event of default.
However, the Company believes it is in compliance with the applicable loan
covenants and an event of default does not exist. Accordingly, the subordinated
debt has not been reflected as a current obligation in the consolidated
financial statements.

  The Company generated cash from operating activities of approximately $13.5
million during the year ended March 31, 1997. The Company's principal uses of
cash during the year ended March 31, 1997 were to prepay the indebtedness from
the Taylor Acquisition and to fund approximately $6.3 million of capital
expenditures for upgrading and purchasing equipment.

                                       30
<PAGE>
  The Company believes that the combination of internally generated cash flow,
the net proceeds from the Offerings and availability under the Credit Facility
should provide the Company with sufficient financing to fund the Company's
operations for at least the next 12 months. There can be no assurance, however,
that the Company will not need additional financing or that such financing will
be available on economically acceptable terms.

DESCRIPTION OF CREDIT FACILITY

  Concurrent with the closing of the Offerings and the Pride Acquisition, the
Company put into place a working capital line of credit (the "Working Line")
with a bank. The maximum availability under the Working Line is the lesser of
(i) $50.0 million or (ii) 80% of eligible accounts receivable that have been
outstanding less than 90 days. The Working Line is secured by a first lien
security interest on all the Company's accounts receivable. Borrowings under the
Working Line mature on February 20, 1999 and bear interest, at a rate the
Company may select from time-to-time, equal to: (i) the Bank's prime rate of
interest or (ii) the applicable margin plus the Wall Street Journal LIBOR rate
of interest; the applicable margin is determined by a ratio of total funded debt
to consolidated EBITDA, but shall never be less than 1.75% nor higher than
2.75%. Under the terms of the agreement relating to the Working Line, the
Company must maintain minimum working capital, tangible net worth, current
ratios and debt to capital ratios. The foregoing description does not purport to
be a complete description of all terms of the Working Line or the Credit
Facility. The Company had not drawn against the Working Line as of March 31,
1997 but has used the line to secure five letters of credit totaling $568,000
related to its worker's compensation insurance program.

INFLATION AND SEASONALITY

  Inflation has not had a significant impact on the Company's operations to date
and the Company's operating revenues have not historically been subject to
significant seasonal changes.

NEW ACCOUNTING PRONOUNCEMENTS -- ACCOUNTING FOR ASSET IMPAIRMENT; ACCOUNTING FOR
STOCK-BASED COMPENSATION; ACCOUNTING FOR EARNINGS PER SHARE

  During March 1995, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("FAS") No. 121, "Accounting for the
Impairment of LongLived Assets and for Long-Lived Assets to Be Disposed Of "
("FAS 121"). The Company adopted FAS 121 effective April 1, 1996. FAS 121
requires that long-lived assets and certain identifiable intangibles to be held
and used by an entity be reviewed for impairment whenever events or changes in
circumstances indicate that the carrying amount of an asset may not be
recoverable. Adoption of this pronouncement had no material effect on the
financial statements.

  In October 1995, the FASB issued FAS No. 123, "Accounting for Stock-Based
Compensation" ("FAS 123"). FAS 123 defines a fair value based method of
accounting for employee stock options or similar equity instruments and
encourages all entities to adopt that

                                       31
<PAGE>
method of accounting for all of their employee stock compensation plans. Under
the fair value based method, compensation cost is measured at the grant date
based on the value of the award and is recognized over the service period of the
award, which is usually the vesting period. However, FAS 123 also allows
entities to continue to measure compensation costs for employee stock
compensation plans using the intrinsic value method of accounting prescribed by
APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25").
Entities electing to remain with the accounting prescribed by APB 25 must make
pro forma disclosures of net income and earnings per share as if the fair value
based method recommended by FAS 123 had been applied. The accounting
requirements of FAS 123 are effective for transactions entered into in years
that begin after December 15, 1995, though they may be adopted on issuance. The
disclosure requirements of FAS 123 are effective for financial statements for
years beginning after December 15, 1995. The Company intends to continue
measuring compensation costs using APB 25 and has provided pro forma disclosures
of net income and earnings per share as if the fair value based method of
accounting under FAS 123 had been applied beginning with its financial
statements for the year ending March 31, 1997.

  In February 1997, the FASB issued FAS No. 128, "Earnings Per Share," which
establishes standards for computing and presenting earnings per share. This
Standard, effective for financial statements issued for periods ending after
December 15, 1997, replaces the presentation of primary earnings per share with
a presentation of basic earnings per share. In addition, this Standard requires
dual presentation of basic and diluted earnings per share on the face of the
statement of operations. The impact of the adoption of FAS No. 128 on earnings
per share for 1996 and 1997 will not be material.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
Dawson Production Services, Inc.:

  We have audited the accompanying consolidated balance sheets of Dawson
Production Services, Inc. and subsidiaries as of March 31, 1996 and 1997, and
the related consolidated statements of income, shareholders' equity, and cash
flows for each of the years in the three-year period ended March 31, 1997. These
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
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

  In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Dawson
Production Services, Inc. and subsidiaries as of March 31, 1996 and 1997, and
the results of their operations and their cash flows for each of the years in
the three-year period ended March 31, 1997, in conformity with generally
accepted accounting principles.

Permian Basin areas of West Texas and New Mexico, and California. The Company's
services are utilized by major oil and gas companies as well as independent
producers to optimize performance of oil and gas wells. The Company recently
acquired the U.S. land-based well servicing operations of Pride Petroleum
Services, Inc.
("Pride").

  As a result of its acquisitions and certain corporate restructuring, the
Company currently has several direct and indirect subsidiaries through which it
conducts a significant portion of its operations. All of the assets acquired
from Pride are held in Dawson Production Partners, L.P., a Delaware limited
partnership (the "Partnership"), and the Company is in the process of
transferring substantially all of its remaining operating assets to the
Partnership. All of the general and limited partnership interests in the
Partnership are owned by two wholly-owned corporate subsidiaries of Dawson;
Dawson Production Management, Inc., a Delaware corporation, owns a 1% general
partnership interest in the Partnership, and Dawson Production Acquisition
Corp., a Delaware corporation owns the remaining 99% limited partnership
interest in the Partnership. Dawson has the following additional wholly owned
subsidiaries: Dawson Production Services de Mexico, S.A. de C.V., and Ubicadora
de Tecnicos, S.A. de C.V., both of which are companies organized under the laws
of Mexico; Taylor Companies, Inc., a Texas corporation; and Mobley Vehicle
Acquisition Corp., a Texas corporation.

PRINCIPLES OF CONSOLIDATION

  The consolidated financial statements include the accounts of the Company and
its subsidiaries. All significant intercompany accounts and transactions have
been eliminated (see note 2).

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 at the date of

                                       39
<PAGE>
the financial statements and the reported amounts of revenues and expenses
during the reporting period. While it is believed that such estimates are
reasonable, actual results could differ from those estimates.

CASH EQUIVALENTS

  For purposes of the statements of cash flows, cash and short-term investments
with an original maturity of three months or less from the date of purchase are
considered to be cash equivalents.

REVENUE RECOGNITION

  The Company generally recognizes revenue when services are rendered.

PROPERTY AND EQUIPMENT

  Property and equipment are stated at cost. Major renewals and improvements are
capitalized and depreciated over the respective asset's useful life.
Expenditures for repairs and maintenance are charged to expense as incurred.
Property and equipment are reviewed for impairment whenever events or
circumstances provide evidence that suggests that the carrying amounts of the
property and equipment may not be recoverable.

  Property and equipment are depreciated over their estimated useful lives on
the straight-line method. Commencing with the acquisition of substantially all
of Pride Petroleum Services, Inc.'s U.S. land-based well servicing operations in
February 1997, the Company has utilized a "component parts" approach to
depreciating fixed assets. Estimated useful lives are as follows:

                                                           ESTIMATED

Well servicing equipment...............................      3-20
Vehicles...............................................       3-5
Office furniture and other equipment...................      5-12

INCOME TAXES

The Company uses the asset and liability method of accounting for income taxes.
Under the asset and liability method, deferred tax assets and liabilities are
recognized for the future tax consequences attributable to temporary differences
between the financial statement carrying amounts of existing assets and
liabilities and their respective tax bases. Deferred tax assets and liabilities
are measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognized in income in the period that includes the enactment date.

                                       40
<PAGE>
INTANGIBLE AND OTHER ASSETS

  Goodwill represents the excess purchase price over fair value of net assets
acquired and is amortized on a straight-line basis over twenty to twenty-five
year periods from the dates of acquisition. Other assets consist principally of
loan costs and are amortized on a straight-line basis over the terms of the
loans.

  Intangible assets are reviewed for impairment whenever events or circumstances
provide evidence that suggests that the carrying amount of the intangible asset
may not be recoverable. The Company assesses the recoverability of the
intangible asset by determining whether the carrying amount of the intangible
asset can be recovered through projected undiscounted future cash flows over the
remaining amortization period.

FAIR VALUES OF FINANCIAL INSTRUMENTS

  The Company's financial instruments consist primarily of short-term, variable
rate items or recently issued debt instruments for which management believes
fair value approximates carrying value. The carrying value of the $140 million
Senior Notes due February 1, 2007 (see note 5) approximates fair value as of
March 31, 1997.

EARNINGS PER SHARE

  Primary earnings per share is computed by deducting preferred dividends from
net income in order to determine net income attributable to common shareholders.
This amount is then divided by the weighted average number of common shares
outstanding and common stock equivalents.

  Earnings per share assuming full dilution is determined by dividing net income
plus tax effected convertible debt interest by the weighted average number of
common shares outstanding during the year after giving effect for common stock
equivalents arising from stock options and for convertible debt or preferred
stock assumed converted to common stock.

  Pursuant to Securities and Exchange Commission Staff Accounting Bulletin No.
83, stock and stock options issued during the twelve months immediately
preceding the Company's initial public offering filing date including those
issued in connection with the minority interest acquisition (see note 2) have
been included in the calculation of common and common equivalent shares using
the treasury stock method and the anticipated public offering price as if they
were outstanding for all periods. Common stock equivalents resulting from the
conversion or exercise of convertible debt or preferred shares and other stock
options are excluded when their result is anti-dilutive.

RECLASSIFICATION

  Certain amounts, as previously presented, have been reclassified to conform
with the current year financial statement presentation.

NEW ACCOUNTING PRONOUNCEMENTS

ACCOUNTING FOR STOCK-BASED COMPENSATION

  In October 1995, the Financial Accounting Standards Board (FASB) issued SFAS
No. 123, "Accounting for Stock-Based Compensation," which sets forth alternative
accounting and disclosure requirements for stock-based compensation
arrangements. SFAS 123 does not rescind the existing accounting for employee
stock-based compensation under APB Opinion No. 25. Companies may continue to
follow the current accounting to measure and recognize employee stock-based
compensation; however, SFAS 123 requires disclosure of pro forma net income and
earnings per share that would have been reported under the "fair value" based
recognition provisions of SFAS 123. The Company has elected to continue to
follow the provisions of APB Opinion No. 25 for employee stock-based
compensation and has disclosed the pro forma information required under SFAS 123
(see note 8).

EARNINGS PER SHARE

  In February 1997, the FASB issued SFAS No. 128, "Earnings Per Share," which
establishes standards for computing and presenting earnings per share. This
Standard, effective for financial statements issued for periods ending after
December 15, 1997, replaces the presentation of primary earnings per share with
a presentation of basic earnings per share. In addition, this Standard requires
dual presentation of basic and diluted earnings per share on the face of the
statement of operations. The impact of the adoption of SFAS No. 128 on earnings
per share for 1996 and 1997 will not be material.

CONCENTRATION OF CREDIT RISK

Financial instruments which potentially subject the Company to concentrations of
credit risk consist primarily of temporary cash investments and trade
receivables. The Company places its temporary cash investments in U.S.
Government securities and in other high quality financial instruments. By policy
the Company limits the amount of credit exposure to any one financial
institution or issuer. The Company's customer base consists primarily of
independent oil and natural gas producers. During the years ended March 31,
1995, 1996 and 1997, the provisions charged to operations to increase the
reserve for doubtful trade accounts receivable were $223,475, $21,714 and
$270,343, respectively. During the years ended March 31, 1995, 1996 and 1997,
sales to the Company's largest customer accounted for approximately 16%, 24% and
20.0%, respectively, of total operating revenues.

(2) ACQUISITIONS

PRIDE

Effective February 20, 1997, the Company acquired Pride for approximately $135.4
million in cash and acquisition costs of $1.9 million. The acquisition has been
accounted for as a purchase and, accordingly, the operating results of Pride
have been included in the Company's consolidated statements of income since the
effective date of acquisition. The excess of the aggregate purchase price over
the fair market value of the net assets acquired was recognized as goodwill and
is being amortized over 25 years. The fair value of assets acquired, including
goodwill of $30.2 million, was $138.0 million and liabilities assumed totaled
$1.8 million. The funds used to acquire Pride were provided by proceeds of sales
of common stock and senior notes through public offerings in February 1997.

TAYLOR COMPANIES, INC.

  Effective July 29, 1996, the Company acquired all of the issued and
outstanding stock of Taylor Companies, Inc. for an aggregate purchase price of
$12,750,000, consisting of $11,000,000 in cash and a $1,750,000 subordinated
promissory note payable to the selling shareholder. Goodwill recognized on this
transaction amounted to approximately $7,350,621, which is being amortized over
a twenty-year period. The final purchase price allocations for the Pride and
Taylor Acquisitions may be adjusted based on the resolution of certain
pre-acquisition issues.

     Assuming the purchases of Pride and Taylor Companies, Inc. had been
consummated as of the beginning of the fiscal year 1996, unaudited pro forma
operating results of the Company would be as follows:

                                                           MARCH 31,

                                              ---------------    --------------
Revenues ..................................   $   182,219,000       205,382,000
Net income (loss) .........................   $    (4,003,000)        2,169,000 
Primary earnings (loss) per share .........   $         (0.56)             0.21
Fully diluted earnings (loss) per share ...   $         (0.56)             0.21

  The pro forma results of operations are not necessarily indicative of the
actual results of operations that would have occurred had the purchase been made
at the beginning of the respective periods.

WELL SOLUTIONS, INC.

  On November 30, 1994, the Company acquired substantially all of the property
and equipment of Well Solutions, Inc. (Well Solutions), a company engaged in
providing oilfield services, for an aggregate purchase price of $18,097,550,
consisting of $15,895,733 in cash, a convertible note payable of $1,500,000 and
closing costs of $701,817. The acquisition has been accounted for as a purchase
and, accordingly, the operating results of Well Solutions have been included in
the Company's consolidated statements of income since the date of acquisition.
The excess of the aggregate purchase price over the fair market value of the net
assets acquired was recognized as goodwill and is being amortized over 20 years.
The fair value of assets acquired, including goodwill of $2,451,818, was
$18,534,355 and liabilities assumed totaled $436,805. The funds used to acquire
Well Solutions were provided by long-term borrowings, proceeds of sales of
common stock and subordinated debt and cash from operations.

OTHER ACQUISITIONS:

  Effective November 1, 1995, the Company acquired the 39% minority interest in
the Company's subsidiary, Dawson WellTech, L.C., from WellTech, Inc. in exchange
for the issuance to WellTech, Inc. of 1,329,495 shares of common stock for a
total purchase price of $7,700,000 based on an independent appraisal of the
common stock. Goodwill recognized on this transaction amounted to $385,000 and
is being amortized over 20 years.

  Effective March 1, 1996, the Company acquired a portion of the assets of a
small company in Giddings, Texas for an aggregate purchase price of
approximately $1,248,000, consisting of $125,000 in cash and $1,123,000 in
capital leases and a note payable. Goodwill recognized on this transaction
amounted to $97,000 and is being amortized over 20 years.

  In April 1996, the Company acquired the assets of two small production testing
companies in Louisiana. The aggregate purchase price was approximately $673,000.
Goodwill and a non-compete agreement were recognized on these transactions which
amounted to approximately $111,000. These items are being amortized over 20 and
five year periods, respectively.

  In May 1996, the Company acquired the Texas-based well servicing division of a
non-affiliated company. The aggregate purchase price was $779,000.

  In July 1996, the Company acquired the assets of a trucking company in
Louisiana. The aggregate purchase price was approximately $400,000. Goodwill
recognized on the transaction amounted to $50,000, which is being amortized over
a 20-year period.

  On January 20, 1997, the Company acquired the liquid services assets of Mobley
Company, Inc. for approximately $5.0 million in cash and a $500,000 five year
subordinated note. Goodwill recognized on this transaction amounted to
$1,566,000 and is being amortized over 20 years.

                                       44
<PAGE>
  The other acquisitions have been accounted for as purchases and, accordingly,
the operating results have been included in the Company's consolidated
statements of income since the dates of acquisition. The effect on results of
operations would not have been material if such other acquisitions had occurred
at the beginning of the year.

(3) MANDATORILY REDEEMABLE PREFERRED STOCK

  In October 1990, the Company issued 80,800 shares of 10% cumulative
convertible preferred stock for a total price of $1,010,000. Each preferred
shareholder was entitled to receive, in preference to common shareholders,
annual dividends in the amount of $1.25 per share, payable quarterly. At the
discretion of the Company, the dividends could have been declared in either cash
or common stock valued at $3.49 a share. Dividends were cumulative and accrued
from the date of the stock issuance. The Company declared dividends on the
preferred stock in the amount of $101,007 in the years ended March 31, 1994 and
1995 and $88,273 in the year ended March 31, 1996.

  Holders of the preferred stock elected to convert 20,200 shares of such stock
into 86,860 shares of common stock, effective October 18, 1995. Pursuant to a
November 1, 1995 Agreement for the Conversion of Securities (the "Conversion
Agreement"), the remaining 60,600 shares of preferred stock converted into
260,580 shares of common stock effective February 19, 1996.

  On February 20, 1997, concurrent with the closing of the Senior Note and
Common Stock offerings and the acquisition of Pride, the Company entered into a
working capital line of credit (the "Working Line") with a bank. The maximum
availability under the Working Line would be the lesser of (i) $50 million or
(ii) 80% of eligible accounts receivable that have been outstanding less than 90
days. The Working Line is secured by a first lien security interest on all the
Company's accounts receivable. Borrowings under the Working Line mature two
years from the date of any such borrowings and bear interest at the lesser of
(i) the Bank's prime rate of interest or (ii) a varying percentage rate ranging
from 1.75% to 2.75%, based on the total funded debt to cash flow ratio, over the
Company's choice of the 30, 90 or 180-day LIBOR rate of interest. The Company
had not drawn against the line as of March 31, 1997, but has used the line to
secure five letters of credit totaling $568,000 related to its worker's
compensation insurance program. Under the terms of the loan agreement, the
Company must maintain minimum working capital, tangible net worth, current
ratios and debt to capital ratios. The foregoing description does not purport to
be a complete description of all terms of the Credit Facility.

  The Company has $3.75 million of subordinated debt outstanding at March 31,
1997. Approximately $1.5 million of the subordinated debt is represented by a
debenture held by Well Solutions, bears interest at 8%, matures on November 30,
1999, is prepayable without penalty at any time, and may be converted at any
time, at the option of the holder, into 37,634 shares of Company Common Stock,
subject to adjustment to prevent dilution. Approximately $1.75 million of
subordinated debt is represented by a subordinated, non-negotiable promissory
note held by PSD Investments, Ltd., which bears interest at 8%, matures on July
26, 2001 and is prepayable without penalty at any time. In addition, $.5 million
of subordinated debt is represented by a promissory note held by Mobley Company,
Inc., which bears interest at 8.5%, matures on January 20, 2002 and is
prepayable without penalty at any time.

  All of the subordinated debt of the Company was incurred in conjunction with
certain acquisitions made by the Company and have offset provisions in
conjunction with unforeseen liabilities that might arise from these
acquisitions. The Company has received a demand for acceleration of payment and
has been served with a lawsuit relating to the $1.75 million of subordinated
debt held by PSD Investments, Ltd. due to an alleged event of default. However,
the Company believes it is in compliance with the applicable loan covenants and
that an event of default does not exist. Accordingly, the subordinated debt has
not been reflected as a current obligation in the consolidated financial
statements.

  In March 1996, the Company elected to prepay a $13,000,000 note payable to a
bank. An extraordinary charge of $513,819 (net of income tax benefit of
$264,495) was incurred as a result of the early extinguishment of the note
payable.

  During fiscal 1995, $75,000 in principal amount of subordinated notes were
converted into 16,125 shares of common stock. During fiscal 1996, $150,000 in
principal amount of subordinated notes were converted into 27,232 shares of
common stock.

  Also, pursuant to the Conversion Agreement, $2.4 million of the Company's
subordinated debt converted into common stock at the rate of one share of common
stock for each $6.98 in principal amount of subordinated debt effective February
19, 1996.

  Scheduled maturities of principal for long-term debt based on balances
outstanding at March 31, 1997 are summarized as follows:

  The Senior Notes due February 1, 2007 (Notes) were issued by the Company in
February 1997. The Notes bear interest at 9 3/8%, payable semi-annually on
February 1 and August 1 of each year, commencing August 1, 1997. The proceeds
from the issuance of the Notes were utilized primarily to acquire Pride (see
note 2) and prepay existing debt. The Notes are redeemable at the option of the
Company, in whole or in part, at any time on or after February 1, 2002, at the
redemption prices included in the indenture agreement, together with accrued and
unpaid interest to the date of redemption. The Notes are unconditionally
guaranteed on a senior unsecured basis by each of the Company's principal
operating subsidiaries. The terms of the indenture related to the Notes contain
covenants limiting, among other things, the incurrence of additional
indebtedness of the Company; dividend payments on or issuance and sales of
capital stock of restricted subsidiaries; payments with respect to certain
subordinated obligations and the making of certain investments; sales of assets;
certain transactions with affiliates; and sale/leaseback transactions.

 (7) SHAREHOLDERS' EQUITY

     (a) EQUITY OFFERINGS

      In March 1996, the Company completed an initial public offering (the
"IPO") of 2,616,202 shares (net of 48 fractional shares paid in cash in
connection with the Recapitalization and Stock Split referred to below) of its
common stock for the purpose of raising funds to acquire additional businesses
and to retire debt. Net proceeds to the Company from the IPO, after deduction of
associated expenses, were approximately $23,522,000.

      In February 1997, the Company completed a secondary public offering of
4,722,259 shares (including 689,773 shares issued in connection with an
over-allotment option) of its common stock for the purpose of raising funds to
acquire Pride and retire debt (see notes 2 and 4). Net proceeds to the Company,
after deduction of associated expenses, were approximately $55,285,000.

                                       48
<PAGE>
     (b) RECAPITALIZATION AND STOCK SPLIT

Effective January 17, 1996, the shareholders approved an amendment to the
Articles of Incorporation which, among other actions, increased the authorized
shares of all classes of capital stock to 20,560,600 and changed the par value
of the common stock to $.01 per share. Share and per share amounts for all
periods presented have been adjusted to reflect these changes. The Board of
Directors approved a 4.3-for-one stock split of the common stock which occurred
on March 1, 1996. Share and per share amounts for all periods presented have
been adjusted to reflect this stock split.

     (c) TREASURY STOCK

  During fiscal 1996, the Company retired all of the common shares held in
treasury. The cost of acquired shares in excess of par value was charged to
additional paid-in capital.

(8) STOCK WARRANTS AND OPTIONS

  In fiscal 1995, 118,250 common stock warrants were issued by the Company to
several officers and directors of the Company. The warrants have an exercise
price of $4.65 per share. During fiscal 1995 and 1996, employees and officers of
the Company exercised their warrants to purchase 40,618 and 36,546 shares,
respectively, of common stock in exchange for notes payable to the Company of
$66,878 and $75,000. The notes are secured by the shares of common stock issued
and the personal guarantees of the officers receiving the stock.

  In October 1995, the Company adopted the 1995 Incentive Plan (the "1995
Plan"). Under the 1995 Plan, incentive options, non-statutory options,
restricted stock awards, and/or stock appreciation rights may be granted to key
employees, non-employee directors and consultants to purchase the Company's
common stock at prices not less than the fair market value at the time of grant,
which become exercisable as described in the respective Award Agreement.
Pursuant to the 1995 Plan, an aggregate of 537,500 shares of the Company's
common stock is available for issuance upon the exercise of such options, awards
and rights, which may be granted over a ten-year period. On October 6, 1995,
options to purchase 133,300 shares of common stock at $7.44 per share were
granted under the 1995 Plan. During fiscal 1997, options to purchase 329,350
shares of common stock at amounts ranging from $10.75 to $12.25 per share were
granted under the 1995 Plan. Also in fiscal 1997, 21,500 and 5,300 options were
exercised and canceled, respectively, under the 1995 Plan.

  The weighted average fair value of stock options granted during 1996 and 1997
was $7.44 and $11.375 per share, respectively. The fair value of each option
grant is estimated on the date of grant using the Black-Scholes options-pricing
model. The model assumed expected volatility of 0% and 47.6%, weighted average
risk-free interest rates of 6.66% and 6.75%, for grants in 1996 and 1997,
respectively, and an expected life of 4 years. As the Company has not declared
dividends since it became a public entity, no dividend yield was used. Actual
value realized, if any, is dependent on the future performance of the Company's
common stock and overall stock market conditions. There is no assurance the
value realized by an optionee will be at or near the value estimated by the
Black-Scholes model.

  As discussed in note 1, no compensation expense has been recorded in 1995,
1996 or 1997 for the Company's stock options. Had compensation cost for the
Company's stock option plans been determined based on the fair-value at the
grant dates for awards made after March 31, 1995 under that plan, the Company's
net income and earnings per common share would have been reduced to the pro
forma amounts indicated below:

  The Company anticipates the reversal of existing taxable temporary differences
will provide sufficient taxable income to realize the benefits of its deferred
tax assets.

  For the year ended March 31, 1996, a decrease in deferred income tax expense
resulted primarily from the purchase of the remaining 39% interest in the
Company's majority owned subsidiary, Dawson WellTech, L.C. (note 2), a reduction
in deferred tax liabilities occurred of approximately $1,400,000 as a result of
the differences in basis of assets for financial reporting and income tax
purposes.

  As discussed in note 2, the Company acquired all of the issued and outstanding
stock of Taylor Companies, Inc. The transaction was accounted for as a purchase
and resulted in an increase in deferred tax liabilities of approximately $2.5
million due to differences in basis of assets for financial reporting and income
tax purposes.

                                       51

  At March 31, 1997, the Company had $869,000 of alternative minimum tax credit
carryforwards available to reduce regular Federal income taxes which have no
expiration date. The Company also has a tax net operating loss carryforward of
approximately $1,885,000 and foreign tax credits of approximately $124,000 for
federal income tax purposes which expire in 2011 and 2002, respectively.

(10) RELATED PARTY TRANSACTIONS

  The Company previously retained a company owned by a member of the Board of
Directors to provide consulting services and makes payments to that company upon
completion of various financing and acquisition transactions. Payments for fees
and expenses for the years ended March 31, 1995, 1996 and 1997 were $147,916,
$47,475 and $18,614, respectively. The payment for the year ended March 31, 1995
includes $122,500 paid as a finder's fee by an investment banking firm from the
fee it received from the Company in connection with an acquisition.

(11) EMPLOYEE BENEFIT PLANS

  The Company has a welfare benefit plan (the "Plan") to provide medical
benefits for eligible employees and their dependents. Contributions to the Plan
are made by the Company and covered employees. The Plan may be terminated at the
discretion of the Company. Contributions to the Plan in the amounts of $571,387,
$686,949 and $1,054,965 were made in fiscal 1995, 1996 and 1997, respectively.

  In addition, the Company made contributions to the Taylor Interests, Inc.
welfare benefit plan to provide medical benefits for those employees hired by
Dawson. Contributions were $187,239 from July 29, 1996 through January 1, 1997,
the date the employees transferred to the Company.

  In fiscal 1993, the Company established a 401(k) savings plan. Eligible
employees can make contributions to the plan. The Company may, at its option,
match a portion of the contributions made by the employees. The Company matched
50% of employee contributions up to a limit of $500 per employee in fiscal 1994,
resulting in total payments of $50,140, which amounts were paid in fiscal 1995.
The Company did not match employee contributions made in fiscal 1995, 1996 or
fiscal 1997.

  As of January 1, 1997, the Company transferred all former Taylor Interests,
Inc. employees hired by Dawson from the Taylor Interests 401(k) savings plan to
the Dawson 401(k) savings plan. Dawson did not match employee contributions made
to either plan by these employees from July 29, 1997 through March 31, 1997.

(12) COMMITMENTS AND CONTINGENCIES

  Under the Company's worker's compensation insurance program, the Company pays
the first $300,000 of all claims with no aggregate limit in any one year.
Provision for claims under the program has been made in the financial statements
which represent the expected future payments based on the estimated ultimate
costs for incidents incurred through the end of each period. The insurance
carrier required the Company to make a deposit of $95,000. The deposit has been
included in other assets in the accompanying balance sheet. In addition, the
Company has established a letter of credit in favor of its respective insurance
carriers (note 4) and has entered into an agreement with an insurance carrier
for the guarantee of deductible reimbursement. The amount of the guarantee for
the year ended March 31, 1997 was $500,000.

  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 position or results of operations.

        The Trustee shall authenticate the Notes for original issue up to the
aggregate principal amount of $140,000,000. The aggregate principal amount of
Notes outstanding at any time may not exceed $140,000,000 except as provided in
Section 2.7 hereof.

        The Trustee may appoint an authenticating agent acceptable to the
Company to authenticate Notes. An authenticating agent may authenticate Notes
whenever the Trustee may do so. Each reference in this Indenture to
authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as an Agent to deal with the Company or
an Affiliate of the Company.

SECTION 2.3    REGISTRAR AND PAYING AGENT.

        The Company shall maintain an office or agency where Notes may be
presented for registration of transfer or for exchange ("REGISTRAR") and an
office or agency where Notes may be presented for payment ("PAYING AGENT"). The
Registrar shall keep a register of the Notes and of their transfer and exchange.
The Company may appoint one or more co-registrars and one or more additional
paying agents. The term "REGISTRAR" includes any co-registrar and the term
"PAYING AGENT" includes any additional paying agent. The Company may change any
Paying Agent or Registrar without notice to any Holder. The Company shall notify
the Trustee in writing of the name and address of any Agent not a party to this
Indenture. If the Company fails to appoint or maintain another entity as
Registrar or Paying Agent, the Trustee shall act as such. The Company or any of
its Subsidiaries may act as Paying Agent or Registrar.

        The Company initially appoints The Depository Trust Company ("DTC") to
act as Depository with respect to the Global Notes.

        The Company initially appoints the Trustee to act as the Registrar and
Paying Agent and to act as Note Custodian with respect to the Global Notes.

SECTION 2.4    PAYING AGENT TO HOLD MONEY IN TRUST.

        The Company shall require each Paying Agent other than the Trustee to
agree in writing that the Paying Agent will hold in trust for the benefit of
Holders or the Trustee all money held by the Paying Agent for the payment of
principal, premium, if any, or interest on the Notes, and will notify the
Trustee of any default by the Company in making any such payment. While any such
default continues, the Trustee may require a Paying Agent to pay all money held
by it to the Trustee. The Company at any time may require a Paying Agent to pay
all money held by it to the Trustee. Upon payment over to the Trustee, the
Paying Agent (if other than the Company or a Subsidiary thereof) shall have no
further liability for the money. If the Company or a Subsidiary thereof acts as
Paying Agent, it shall segregate and hold in a separate trust fund for the
benefit of the Holders all money held by it as Paying Agent. Upon any bankruptcy
or reorganization proceedings relating to the Company, the Trustee shall serve
as Paying Agent for the Notes.

                                       18

SECTION 2.5    HOLDER LISTS.

        The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
all Holders and shall otherwise comply with TIA ss. 312(a). If the Trustee is
not the Registrar, the Company shall furnish to the Trustee at least seven
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of the Holders of
Notes and the Company shall otherwise comply with TIA ss. 312(a).

SECTION 2.6    TRANSFER AND EXCHANGE.

               (a) TRANSFER AND EXCHANGE OF DEFINITIVE NOTES. When Definitive
Notes are presented by a Holder to the Registrar with a request:

                        (x) to register the transfer of the Definitive Notes; or

                        (y) to exchange such Definitive Notes for an equal
        principal amount of Definitive Notes of other authorized denominations,

the Registrar shall register the transfer or make the exchange as requested if
its requirements for such transactions are met; provided, however, that the
Definitive Notes presented or surrendered for register of transfer or exchange
shall be duly endorsed or accompanied by a written instruction of transfer in
form satisfactory to the Registrar duly executed by such Holder or by his
attorney, duly authorized in writing.

               (b) TRANSFER OF A DEFINITIVE NOTE FOR A BENEFICIAL INTEREST IN A
GLOBAL NOTE. A Definitive Note may not be exchanged for a beneficial interest in
a Global Note except upon satisfaction of the requirements set forth below. Upon
receipt by the Trustee of a Definitive Note, duly endorsed or accompanied by
appropriate instruments of transfer, in form satisfactory to the Trustee,
together with written instructions from the Holder thereof directing the Trustee
to make, or to direct the Note Custodian to make, an endorsement on the Global
Note to reflect an increase in the aggregate principal amount of the Global
Note, in which case the Trustee shall cancel such Definitive Note in accordance
with Section 2.11 hereof and cause, or direct the Note Custodian to cause, in
accordance with the standing instructions and procedures existing between the
Depository and the Note Custodian, the aggregate principal amount of the Global
Note to be increased accordingly. If no Global Note is then outstanding, the
Company shall issue and, upon receipt of an authentication order in accordance
with Section 2.2 hereof, the Trustee shall authenticate,a new Global Note in the
appropriate principal amount.

               (c) TRANSFER AND EXCHANGE OF GLOBAL NOTE. The transfer and
exchange of the Global Note or beneficial interests therein shall be effected
through the Depository, in accordance with this Indenture and the procedures of
the Depository therefor, which shall include restrictions on transfer comparable
to those set forth herein to the extent required by the Securities Act.

               (d) TRANSFER OF A BENEFICIAL INTEREST IN A GLOBAL NOTE FOR A
DEFINITIVE NOTE.

                        (i) Any Person having a beneficial interest in a Global
        Note may upon request exchange such beneficial interest for a Definitive
        Note. Upon receipt by the Trustee of written instructions or such other
        form of instructions as is customary for the Depository, from the
        Depository or its nominee on behalf of any Person having a beneficial
        interest in a Global 

                                       19
<PAGE>
        Note, the Trustee or the Note Custodian, at the direction of the
        Trustee, shall, in accordance with the standing instructions and
        procedures existing between the Depository and the Note Custodian, cause
        the aggregate principal amount of a Global Note to be reduced
        accordingly and, following such reduction, the Company shall execute and
        the Trustee shall authenticate and deliver to the transferee a
        Definitive Note in the appropriate principal amount.

                      (ii) Definitive Notes issued in exchange for a beneficial
        interest in a Global Note pursuant to this Section 2.6(d) shall be
        registered in such names and in such authorized denominations as the
        Depository, pursuant to instructions from its direct or indirect
        participants or otherwise, shall instruct the Trustee. The Trustee shall
        deliver such Definitive Notes to the Persons in whose names such Notes
        are so registered.

               (e) RESTRICTIONS ON TRANSFER AND EXCHANGE OF GLOBAL NOTE.
Notwithstanding any other provision of this Indenture (other than the provisions
set forth in subsection (f) of this Section 2.6), a Global Note may not be
transferred as a whole except by the Depository to a nominee of the Depository
or by a nominee of the Depository to the Depository or another nominee of the
Depository or by the Depository or any such nominee to a successor Depository or
a nominee of such successor Depository.

               (f) AUTHENTICATION OF DEFINITIVE NOTES IN ABSENCE OF DEPOSITORY.
If at any time:

                      (i) the Depository for the Notes notifies the Company that
        the Depository is unwilling or unable to continue as Depository for the
        Global Note and a successor Depository for the Global Note is not
        appointed by the Company within 90 days after delivery of such notice;
        or

                      (ii) the Company, at its discretion, notifies the Trustee
        in writing that it elects to cause the issuance of Definitive Notes
        under this Indenture,

then the Company shall execute, and the Trustee shall authenticate and deliver,
Definitive Notes in an aggregate principal amount equal to the principal amount
of the Global Note in exchange for such Global Note.

               (g) CANCELLATION AND/OR ADJUSTMENT OF GLOBAL NOTE. At such time
as all beneficial interests in a Global Note have been exchanged for Definitive
Notes, redeemed, repurchased or canceled, the Global Note shall be returned to
or retained and canceled by the Trustee in accordance with Section 2.11 hereof.
At any time prior to such cancellation, if any beneficial interest in a Global
Note is exchanged for Definitive Notes, redeemed, repurchased or canceled, the
principal amount of Notes represented by such Global Note shall be reduced
accordingly and an endorsement shall be made on such Global Note, by the Trustee
or the Note Custodian, at the direction of the Trustee, to reflect such
reduction.

               (h)    GENERAL PROVISIONS RELATING TO TRANSFERS AND EXCHANGES.

                      (i) To permit registrations of transfers and exchanges,
        the Company shall execute and the Trustee shall authenticate Definitive
        Notes and Global Notes at the Registrar's request.

                                       20
<PAGE>
                      (ii) No service charge shall be made to a Holder for any
        registration of transfer or exchange, but the Company may require
        payment of a sum sufficient to cover any transfer tax or similar
        governmental charge payable in connection therewith (other than any such
        transfer taxes or similar governmental charge payable upon exchange or
        transfer pursuant to Sections 3.7, 3.9, 4.10, 4.15 and 9.5 hereto).

                      (iii) The Registrar shall not be required to register the
        transfer or exchange of any Note selected for redemption in whole or in
        part, except the unredeemed portion of any Note being redeemed in part.

                      (iv) All Definitive Notes and Global Notes issued upon any
        registration of transfer or exchange of Definitive Notes or Global Notes
        shall be the valid obligations of the Company, evidencing the same debt,
        and entitled to the same benefits under this Indenture, as the
        Definitive Notes or Global Notes surrendered upon such registration of
        transfer or exchange.

                      (v)    The Company shall not be required:

                             (A) to issue, to register the transfer of or to
               exchange Notes during a period beginning at the opening of
               business 15 days before the day of any selection of Notes for
               redemption under Section 3.2 hereof and ending at the close of
               business on the day of selection;

                             (B) to register the transfer of or to exchange any
               Note so selected for redemption in whole or in part, except the
               unredeemed portion of any Note being redeemed in part; or

                             (C) to register the transfer of or to exchange a
               Note between a record date and the next succeeding interest
               payment date.

               (i) Prior to due presentment for the registration of a transfer
of any Note, the Trustee, any Agent and the Company may deem and treat the
Person in whose name any Note is registered as the absolute owner of such Note
for the purpose of receiving payment of principal of and interest on such Notes,
and neither the Trustee, any Agent nor the Company shall be affected by notice
to the contrary.

SECTION 2.7    REPLACEMENT NOTES.

        If any mutilated Note is surrendered to the Trustee or the Company, and
the Trustee receives evidence to its satisfaction of the destruction, loss or
theft of any Note, the Company shall issue and the Trustee shall authenticate a
replacement Note if the Trustee's requirements are met. If required by the
Trustee or the Company, an indemnity bond must be supplied by the Holder that is
sufficient in the judgment of the Trustee and the Company to protect the
Company, the Trustee, any Agent and any authenticating agent from any loss that
any of them may suffer if a Note is replaced. The Company may charge for its
expenses in replacing a Note.

        Every replacement Note is an additional obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Notes duly issued hereunder.

                                       21
<PAGE>
SECTION 2.8    OUTSTANDING NOTES.

        The Notes outstanding at any time are all the Notes authenticated by the
Trustee except for those canceled by it, those delivered to it for cancellation,
those redeemed, those reductions in the interest in a Global Note effected by
the Trustee in accordance with the provisions hereof, and those described in
this Section as not outstanding. Except as set forth in Section 2.9 hereof, a
Note does not cease to be outstanding because the Company, any of the Subsidiary
Guarantors or any Affiliate of the Company or any of the Subsidiary Guarantors
holds the Note.

        If a Note is replaced pursuant to Section 2.7 hereof, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Note is held by a bona fide purchaser.

        If the principal amount of any Note is considered paid under Section 4.1
hereof, it ceases to be outstanding and interest on it ceases to accrue.

        If the Paying Agent (other than the Company, a Subsidiary or an
Affiliate of any thereof) holds, on a redemption date or maturity date, money
sufficient to pay Notes payable on that date, then on and after that date such
Notes shall be deemed to be no longer outstanding and shall cease to accrue
interest.

SECTION 2.9    TREASURY NOTES.

        In determining whether the Holders of the required principal amount of
Notes have concurred in any direction, waiver or consent, Notes owned by the
Company, any of the Subsidiary Guarantors or any Affiliate of the Company or any
of the Subsidiary Guarantors, shall be considered as though not outstanding,
except that for the purposes of determining whether the Trustee shall be
protected in relying on any such direction, waiver or consent, only Notes that
the Trustee actually knows are so owned shall be so disregarded.

SECTION 2.10   TEMPORARY NOTES.

        Until Definitive Notes are ready for delivery, the Company may prepare
and the Trustee shall authenticate temporary Notes upon a written order of the
Company signed by two Officers thereof. Temporary Notes shall be substantially
in the form of Definitive Notes but may have variations that the Company
considers appropriate for temporary Notes and as shall be reasonably acceptable
to the Trustee. Without unreasonable delay, the Company shall prepare and the
Trustee shall authenticate Definitive Notes or the Global Note in exchange for
temporary Notes.

        Holders of temporary Notes shall be entitled to all of the benefits of
this Indenture.

SECTION 2.11   CANCELLATION.

        The Company at any time may deliver Notes to the Trustee for
cancellation. The Registrar and Paying Agent shall forward to the Trustee any
Notes surrendered to them for registration of transfer, exchange or payment. The
Trustee and no one else shall cancel all Notes surrendered for registration of
transfer, exchange, payment, redemption, replacement or cancellation and shall
destroy such canceled Notes. The Trustee shall provide a certificate of
destruction to the Company from time to time, at the written request of the
Company. The Company may not issue new Notes to replace Notes that it has paid
or that have been delivered to the Trustee for cancellation. If the Company or
any Subsidiary Guarantor 

                                       22
<PAGE>
shall acquire any of the Notes, such acquisition shall not operate as a
redemption or satisfaction of the Indebtedness represented by such Securities
unless and until the same are surrendered to the Trustee for cancellation
pursuant to this Section 2.11.

SECTION 2.12   DEFAULTED INTEREST.

        If the Company defaults in a payment of interest on the Notes, it shall
pay the defaulted interest in any lawful manner plus, to the extent lawful,
interest payable on the defaulted interest, to the Persons who are Holders on a
subsequent special record date, in each case at the rate provided in the Notes
and in Section 4.1 hereof. The Company shall notify the Trustee in writing of
the amount of defaulted interest proposed to be paid on each Note and the date
of the proposed payment. The Company shall fix or cause to be fixed each such
special record date and payment date, provided that no such special record date
shall be less than 10 days prior to the related payment date for such defaulted
interest. At least 15 days before the special record date, the Company (or, upon
the written request of the Company, the Trustee in the name and at the expense
of the Company) shall mail or cause to be mailed to Holders a notice that states
the special record date, the related payment date and the amount of such
interest to be paid.

SECTION 2.13   CUSIP NUMBERS.

        The Company in issuing the Notes may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use CUSIP numbers in notices of
redemption as a convenience to Holders; provided that any such notice may state
that no representation is made as to the correctness of such numbers either as
printed on the Notes or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Notes, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company shall promptly notify the Trustee of any
change in the CUSIP numbers.

                                    ARTICLE 3

                            REDEMPTION AND PREPAYMENT

SECTION 3.1    NOTICES TO TRUSTEE.

        If the Company elects to redeem Notes pursuant to the optional
redemption provisions of Section 3.7 hereof, it shall furnish to the Trustee, at
least 30 days but not more than 60 days before a redemption date, an Officers'
Certificate setting forth (i) the clause of this Indenture pursuant to which the
redemption shall occur, (ii) the redemption date, (iii) the principal amount of
Notes to be redeemed and (iv) the redemption price.

SECTION 3.2    SELECTION OF NOTES TO BE REDEEMED.

        If less than all of the Notes are to be redeemed at any time, the
Trustee shall select the Notes to be redeemed among the Holders of the Notes in
compliance with the requirements of the principal national securities exchange,
if any, on which the Notes are listed or, if the Notes are not so listed, on a
pro rata basis, by lot or in accordance with any other method the Trustee
considers fair and appropriate; provided that no Notes of $1,000 or less will be
redeemed in part. In the event that less than all of the 

                                       23
<PAGE>
Notes are to be redeemed by lot, the particular Notes to be redeemed shall be
selected, unless otherwise provided herein, not less than 30 nor more than 60
days prior to the redemption date by the Trustee from the outstanding Notes not
previously called for redemption.

        The Trustee shall promptly notify the Company in writing of the Notes
selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed. Notes and portions of
Notes selected shall be in amounts of $1,000 or whole multiples of $1,000;
except that if all of the Notes of a Holder are to be redeemed, the entire
outstanding amount of Notes held by such Holder shall be redeemed. Except as
provided in the preceding sentence, provisions of this Indenture that apply to
Notes called for redemption also apply to portions of Notes called for
redemption.

        The provisions of the two preceding paragraphs of this Section 3.2 shall
not apply with respect to any redemption affecting only a Global Note, whether
such Global Note is to be redeemed in whole or in part. In case of any such
redemption in part, the unredeemed portion of the principal amount of the Global
Note shall be in an authorized denomination.

SECTION 3.3    NOTICE OF REDEMPTION.

        Subject to the provisions of Section 3.9 hereof, at least 30 days but
not more than 60 days before a redemption date, the Company shall mail or cause
to be mailed, by first class mail, a notice of redemption to each Holder whose
Notes are to be redeemed at its registered address. Failure to receive such
notice or any defect in the notice to any such Holder shall not affect the
validity of the proceedings for the redemption of any other Notes or portion
thereof.

        The notice shall identify the Notes to be redeemed (including CUSIP
number) and shall state:

                      (i)   the redemption date;

                      (ii)  the redemption price;

                      (iii) if any Note is being redeemed in part, the portion
        of the principal amount of such Note to be redeemed and that, after the
        redemption date upon surrender of such Note, a new Note or Notes in
        principal amount equal to the unredeemed portion shall be issued upon
        cancellation of the original Note;

                      (iv)  the name and address of the Paying Agent;

                      (v)   that Notes called for redemption must be surrendered
        to the Paying Agent to collect the redemption price;

                      (vi)  that, unless the Company's defaults in making such
        redemption payment, interest on Notes called for redemption ceases to
        accrue on and after the redemption date;

                      (vii) the paragraph of the Notes and/or Section of this
        Indenture pursuant to which the Notes called for redemption are being
        redeemed; and

                      (viii) that no representation is made as to the
        correctness or accuracy of the CUSIP number, if any, listed in such
        notice or printed on the Notes.

                                       24
<PAGE>
        If any of the Notes to be redeemed is in the form of a Global Note, then
the Company shall modify such notice to the extent necessary to accord with the
procedures of the Depository applicable to redemption.

        At the Company's request, the Trustee shall give the notice of
redemption in the Company's name and at its expense; PROVIDED, HOWEVER, that the
Company shall have delivered to the Trustee, at least 45 days (unless the
Trustee and the Company agree to a shorter period) prior to the redemption date,
an Officers' Certificate requesting that the Trustee give such notice and
setting forth the information to be stated in such notice as provided in the
preceding paragraph.

SECTION 3.4    EFFECT OF NOTICE OF REDEMPTION.

        Once notice of redemption is mailed in accordance with Section 3.3
hereof, Notes called for redemption become irrevocably due and payable on the
redemption date at the redemption price. A notice of redemption may not be
conditional.

SECTION 3.5    DEPOSIT OF REDEMPTION PRICE.

        One Business Day prior to the redemption date, the Company shall deposit
with the Trustee or with the Paying Agent (or, if the Company is acting as its
own Paying Agent, segregate and hold in trust as provided in Section 2.4 hereof)
money sufficient to pay the redemption price of and accrued interest on all
Notes to be redeemed on that date. The Trustee or the Paying Agent shall
promptly return to the Company any money deposited with the Trustee or the
Paying Agent by the Company in excess of the amounts necessary to pay the
redemption price of, and accrued interest on, all Notes to be redeemed.

        If the Company complies with the provisions of the preceding paragraph,
on and after the redemption date, interest shall cease to accrue on the Notes or
the portions of Notes called for redemption. If a Note is redeemed on or after
an interest record date but on or prior to the related interest payment date,
then any accrued and unpaid interest shall be paid to the Person in whose name
such Note was registered at the close of business on such record date. If any
Note called for redemption shall not be so paid upon surrender for redemption
because of the failure of the Company to comply with the preceding paragraph,
interest shall be paid on the unpaid principal, from the redemption date until
such principal is paid, and to the extent lawful on any interest not paid on
such unpaid principal, in each case at the rate provided in the Note and in
Section 4.1 hereof.

SECTION 3.6    NOTES REDEEMED IN PART.

        Upon surrender of a Note that is redeemed in part, the Company shall
issue and the Trustee shall authenticate for the Holder at the expense of the
Company a new Note equal in principal amount to the unredeemed portion of the
Note surrendered.

SECTION 3.7    OPTIONAL REDEMPTION.

               (a) The Notes will not be redeemable at the Company's option
prior to February 1, 2002. Thereafter, the Notes will be subject to redemption

more than 60 days' notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest thereon to
the applicable 

                                       25

               (b) Notwithstanding the foregoing, at any time on or prior to
February 1, 2000, the Company may redeem up to an aggregate of $49.0 million
principal amount of Notes at a redemption price of 109.375% of the principal
amount thereof, plus accrued and unpaid interest thereon to the redemption date,
with the net proceeds of a Public Equity Offering; PROVIDED that at least $91.0
million in aggregate principal amount of Notes remain outstanding immediately
after the occurrence of such redemption; and, PROVIDED, FURTHER; that such
redemption shall occur within 60 days of the date of the closing of such Public
Equity Offering.

               (c) Any redemption pursuant to this Section 3.7 shall be made
pursuant to the provisions of Sections 3.1 through 3.6 hereof.

SECTION 3.8    MANDATORY REDEMPTION.

        Except as set forth under Sections 4.10 and 4.15 hereof, the Company
shall not be required to make mandatory redemption payments or sinking fund
payments with respect to the Notes.

SECTION 3.9    OFFER TO PURCHASE BY APPLICATION OF EXCESS PROCEEDS.

               (a) In the event that, pursuant to Section 4.10 hereof, the
Company shall be required to commence an Asset Sale Offer, it shall follow the

               not tendered shall continue to accrue interest;

                              (D) that, unless the Company defaults in the
               payment of the purchase price for the Notes payable pursuant to
               the Asset Sale Offer, any such Notes accepted for payment
               pursuant to the Asset Sale Offer shall cease to accrue interest,

               3.9(a)(iii)(H) hereof) and may not elect to have only a portion
               of such Note purchased;

                              (F) that Holders electing to have a Note purchased
               pursuant to any Asset Sale Offer shall be required to surrender
               the Note, with the form entitled "Option of Holder to Elect
               Purchase" on the reverse of the Note completed to the Company or

               of the Holder, the principal amount of the Note the Holder
               delivered for purchase and a statement that such Holder is

               Notes surrendered by Holders exceeds the Offer Amount or less
               than all of the Notes tendered pursuant to the Asset Sale Offer
               are accepted for payment by the Company for any reason consistent
               with this Indenture, the Trustee shall select the Notes to be
               purchased in compliance with the requirements of the principal
               national securities exchange, if any, on which the Notes are
               listed or, if the Notes are not so listed, on a pro rata basis,
               by lot or by such method as the Trustee deems fair and
               appropriate; PROVIDED that Notes accepted for payment in part
               will only be purchased in integral multiples of $1,000; and

                              (I) that Holders whose Notes were purchased only
               in part shall be issued new Notes equal in principal amount to

<PAGE>
        If any of the Notes subject to an Asset Sale Offer is in the form of a
Global Note, then the Company shall modify such notice to the extent necessary
to accord with the procedures of the Depository applicable to repurchases.

               (b) On the Asset Sale Offer Purchase Date, the Company shall: (i)

and mail to any such Holder of Notes accepted for payment in part a new Note
equal in principal amount to any unpurchased portion of the Notes, and any Note
not accepted for payment in whole or in part shall be promptly returned to the

Offer to Holders of the Notes on or as soon as practicable after the Asset Sale
Offer Purchase Date. The Company shall comply with the requirements of Rule
14e-1 under the Exchange Act, and any other securities laws or regulations, if

SECTION 4.1    PAYMENT OF NOTES.

        The Company shall pay or cause to be paid the principal of, premium, if
any, and interest on the Notes on the dates and in the manner provided in the
Notes. Principal, premium, if any, and interest shall be considered paid on the
date due if the Paying Agent, if other than the Company or a Subsidiary thereof,

deposited by the Company in immediately available funds and designated for and
sufficient to pay all principal, premium, if any, and interest then due.

        The Company shall pay interest (including post-petition interest in any
proceeding under any Bankruptcy Law) on overdue principal at the rate equal to
1.0% per annum in excess of the then applicable interest rate on the Notes to
the extent lawful; it shall pay interest (including post-petition interest in
any proceeding under any Bankruptcy Law) on overdue installments of interest
(without regard to any applicable grace period) at the same rate to the extent
lawful.

SECTION 4.2    MAINTENANCE OF OFFICE OR AGENCY.

        The Company shall maintain in the Borough of Manhattan, the City of New

of the Trustee, Registrar or co-registrar) where Notes may be presented for
payment, surrendered for registration of transfer or for exchange and where
notices and demands to or upon the Company in respect of the Notes and this
Indenture may be served. The Company shall give prompt written notice to the
Trustee of the location, and any change 

                                       28

to maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee.

        The Company may also from time to time designate one or more other
offices or agencies where the Notes may be presented or surrendered for any or
all such purposes and may from time to time rescind such designations; PROVIDED,
HOWEVER, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, the City of New York for such purposes. The Company shall give prompt
written notice to the Trustee of any such designation or rescission and of any
change in the location of any such other office or agency.

        The Company hereby designates the Corporate Trust Office of the Trustee
as one such office or agency of the Company in accordance with Section 2.3
hereof.

SECTION 4.3    REPORTS.

               (a) Whether or not required by the rules and regulations of the
Commission, so long as any Notes are outstanding, the Company shall furnish to
the Holders of Notes (i) either the actual Forms 10-Q and 10-K filed with the
Commission, or all quarterly and annual financial information that would be
required to be contained in a filing with the Commission on Forms 10-Q and 10-K

the Company's certified independent accountants and (ii) either any actual Form
8-K filed with the Commission, or all information that would be required to be

required to file such Form. In addition, whether or not required by the rules
and regulations of the Commission, the Company shall file a copy of all such
information and reports with the Commission for public availability (unless the
Commission will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request. The Company shall at
all times comply with TIA ss. 314(a).

               (b) Delivery of such reports, information and documents to the
Trustee is for informational purposes only and the Trustee's receipt of such
shall not constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company'
compliance with any of the covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

SECTION 4.4    COMPLIANCE CERTIFICATE.

               (a) The Company shall deliver to the Trustee, within 90 days
after the end of each fiscal year, an Officers' Certificate stating that a
review of the activities of the Company and its Subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has kept, observed,
performed and fulfilled its obligations under this Indenture, and further
stating, as to each such Officer signing such certificate, that to the best of
his or her knowledge the Company has kept, observed, performed and fulfilled
each and every covenant contained in this Indenture and is not in default in the
performance or observance of any of the terms, provisions and conditions of this
Indenture (or, if a Default or Event of Default shall have occurred and is
continuing, describing all such Defaults or Events of Default of which he or
she may 

                                       29
<PAGE>
have knowledge and what action the Company is taking or proposes to take with
respect thereto) and that to the best of his or her knowledge no event has
occurred and remains in existence by reason of which payments on account of the
principal of or interest, if any, on the Notes is prohibited or if such event
has occurred, a description of the event and what action the Company is taking
or proposes to take with respect thereto.

               (b) So long as not contrary to the then current recommendations
of the American Institute of Certified Public Accountants, the year-end
financial statements delivered pursuant to Section 4.3(a) above shall be
accompanied by a written statement of the Company's independent public
accountants (who shall be a firm of established national reputation) that in
making the examination necessary for certification of such financial statements,
nothing has come to their attention that would lead them to believe that the
Company has violated any provisions of Article 4 or Article 5 hereof or, if any
such violation has occurred, specifying the nature and period of existence
thereof, it being understood that such accountants shall not be liable directly
or indirectly to any Person for any failure to obtain knowledge of any such
violation.

               (c) The Company shall, so long as any of the Notes are
outstanding, deliver to the Trustee, forthwith upon any Officer becoming aware
of any Default or Event of Default, an Officers' Certificate specifying such
Default or Event of Default and what action the Company is taking or proposes to
take with respect thereto.

SECTION 4.5    TAXES.

        The Company shall pay, and shall cause each of its Subsidiaries to pay,
prior to delinquency, all material taxes, assessments, and governmental levies
except such as are contested in good faith and by appropriate proceedings or
where the failure to effect such payment is not adverse in any material respect
to the Holders of the Notes.

SECTION 4.6    STAY, EXTENSION AND USURY LAWS.

        The Company covenants (to the extent that it may lawfully do so) that it
shall not at any time insist upon, plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay, extension or usury law wherever
enacted, now or at any time hereafter in force, that may affect the covenants or
the performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it shall not, by resort to any such law, hinder, delay
or impede the execution of any power herein granted to the Trustee, but shall
suffer and permit the execution of every such power as though no such law has
been enacted.

SECTION 4.7    RESTRICTED PAYMENTS.

        The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly: (i) declare or pay any dividend or make
any other payment or distribution on account of the Company's or any of its
Restricted Subsidiaries' Equity Interests (including, without limitation, any
payment in connection with any merger or consolidation involving the Company) or
to the direct or indirect holders of the Company's Equity Interests in their
capacity as such (other than dividends or distributions payable in Equity
Interests (other than Disqualified Stock) of the Company or dividends or
distributions payable to the Company or any Wholly Owned Restricted Subsidiary
of the Company); (ii) purchase, redeem or otherwise acquire or retire for value
any Equity Interests of the Company or any 

                                       30
<PAGE>
Affiliate of the Company (other than (A) any such Equity Interests owned by the
Company or any Wholly Owned Restricted Subsidiary of the Company that is a
Subsidiary Guarantor and (B) Employee Stock Repurchases); (iii) make any
principal payment on, or purchase, redeem, defease or otherwise acquire or
retire for value any Subordinated Indebtedness (other than $3.75 million of
Subordinated Indebtedness which is Existing Indebtedness, provided that such
Subordinated Indebtedness is redeemed or repaid at or below par), except in
accordance with the mandatory redemption or repayment provisions set forth in
the documentation governing such Indebtedness or (iv) make any Restricted
Investment (all such payments and other actions set forth in clauses (i) through
(iv) above being collectively referred to as "RESTRICTED PAYMENTS"), unless, at
the time of and after giving effect to such Restricted Payment:

                (a) no Default or Event of Default shall have occurred and be
        continuing or would occur as a consequence thereof;

                (b) the Company would, at the time of such Restricted Payment
        and after giving pro forma effect thereto as if such Restricted Payment
        had been made at the beginning of the applicable four-quarter period,
        have been permitted to incur at least $1.00 of additional Indebtedness
        (in addition to Permitted Indebtedness) pursuant to the Fixed Charge
        Coverage Ratio test set forth in Section 4.9(a) hereof; and

                (c) such Restricted Payment, together with the aggregate of all
        other Restricted Payments made by the Company and its Restricted
        Subsidiaries after the Issue Date (excluding Restricted Payments
        permitted by clauses (x) and (y) of the next succeeding paragraph, but
        including the Restricted Payment permitted by clause (z) of the next
        succeeding paragraph), is less than the sum of (i) 50% of the
        Consolidated Net Income of the Company for the period (taken as one
        accounting period) from the beginning of the first fiscal quarter
        commencing after the Issue Date to the end of the Company's most
        recently ended fiscal quarter for which internal financial statements
        are available at the time of such Restricted Payment (or, if such
        Consolidated Net Income for such period is a deficit, less 100% of such
        deficit), plus (ii) 100% of the aggregate Net Equity Proceeds (A)
        received by the Company from the issue or sale, subsequent to the Issue
        Date, of Qualified Capital Stock of the Company or (B) of any other
        Equity Interests or debt securities of the Company that have been issued
        subsequent to the Issue Date and that have been converted into such
        Qualified Capital Stock (other than any Qualified Capital Stock sold to
        a Restricted Subsidiary of the Company) plus (iii) to the extent not
        otherwise included in Consolidated Net Income, the net reduction in
        Investments in Unrestricted Subsidiaries resulting from dividends,
        repayments of loans or advances, or other transfers of assets, in each
        case to the Company or a Restricted Subsidiary after the Issue Date from
        any Unrestricted Subsidiary or from the redesignation of an Unrestricted
        Subsidiary as a Restricted Subsidiary (valued as provided below), plus
        (iv) $10.0 million.

        The foregoing provisions shall not prohibit any of the following: (w)
the payment of any dividend within 60 days after the date of declaration
thereof, if at said date of declaration such payment would have complied with
the provisions of this Indenture; (x) the redemption, repurchase, retirement or
other acquisition of any Equity Interests of the Company in exchange for, or out
of the Net Equity Proceeds of, the substantially concurrent sale (other than to
a Restricted Subsidiary of the Company) of Qualified Capital Stock of the
Company (other than any Disqualified Stock); PROVIDED that the amount of any
such Net Equity Proceeds that are utilized for any such redemption, repurchase,
retirement or other acquisition shall be excluded from clause (c)(ii) of the
preceding paragraph and (y) the defeasance, redemption or repurchase of
Subordinated Indebtedness with the net cash proceeds from an incurrence of
Permitted 

                                       31
<PAGE>
Refinancing Indebtedness or the substantially concurrent sale (other than to a
Restricted Subsidiary of the Company) of Qualified Capital Stock of the Company;
PROVIDED that the amount of any such net cash proceeds that are utilized for any
such redemption, repurchase, retirement or other acquisition shall be excluded
from clause (c)(ii) of the preceding paragraph.

        For purposes of the foregoing provisions, the amount of any Restricted
Payment (other than cash) shall be the fair market value (evidenced by a
resolution of the Board of Directors set forth in an Officers' Certificate
delivered to the Trustee) on the date of the Restricted Payment of the asset(s)
proposed to be transferred by the Company or such Restricted Subsidiary, as the
case may be, pursuant to the Restricted Payment. Not later than five days
following the date of making any Restricted Payment, the Company shall deliver
to the Trustee an Officers' Certificate stating that such Restricted Payment is
permitted and setting forth the basis upon which the calculations required by
this Section 4.7 were computed, which calculations may be based upon the
Company's latest available financial statements.

        The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would be permitted by the provisions
of this Section 4.7 and if such Restricted Subsidiary otherwise meets the
definition of an Unrestricted Subsidiary. For purposes of making such
determination, all outstanding Investments by the Company and its Restricted
Subsidiaries (except to the extent repaid in cash prior to such designation) in
the Restricted Subsidiary so designated will be deemed to be Restricted Payments
at the time of such designation and will reduce the amount available for
Restricted Payments under paragraph (c) of this Section 4.7. All such
outstanding Investments will be deemed to constitute Investments in an amount
equal to the Fair Market Value of such Investments at the time of such
designation.

SECTION 4.8    DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES.

        The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, directly or indirectly, create or otherwise cause or suffer to
exist or become effective any encumbrance or restriction on the ability of any
Restricted Subsidiary to (i)(a) pay dividends or make any other distributions to
the Company or any of its Restricted Subsidiaries (1) on its Capital Stock or
(2) with respect to any other interest or participation in, or measured by, its
profits or (b) pay any indebtedness owed to the Company or any of its Restricted
Subsidiaries, (ii) make loans or advances to the Company or any of its
Restricted Subsidiaries or (iii) transfer any of its properties or assets to the
Company or any of its Restricted Subsidiaries, except for such encumbrances or
restrictions existing under or by reason of (r) Existing Indebtedness as in
effect on the Issue Date, (s) the Credit Facility as in effect as of the Issue
Date, and any amendments, modifications, restatements, renewals, increases,
supplements, refundings, replacements or refinancings thereof, PROVIDED that
such amendments, modifications, restatements, renewals, increases, supplements,
refundings, replacement or refinancings are no more restrictive with respect to
such dividend and other payment restrictions than those contained in the Credit
Facility as in effect on the Issue Date, (t) this Indenture and the Notes, (u)
applicable law, (v) any instrument governing Indebtedness or Capital Stock of a
Person acquired by the Company or any of its Restricted Subsidiaries as in
effect at the time of such acquisition (except to the extent such Indebtedness
was incurred in connection with or in contemplation of such acquisition), which
encumbrance or restriction is not applicable to any Person, or the properties or
assets of any Person, other than the Person, or the property or assets of the
Person, so acquired, PROVIDED that, in the case of Indebtedness, such
Indebtedness was permitted by the terms of Section 4.9 hereof to be incurred,
(w) by reason of customary non-assignment provisions in leases entered into in
the ordinary course of business and customary provisions in other agreements
that restrict assignment of such agreements or rights thereunder, (x) customary
restrictions contained in asset sale 

                                       32
<PAGE>
agreements limiting the transfer of such assets pending the closing of such
sale, (y) purchase money obligations for property acquired in the ordinary
course of business that impose restrictions of the nature described in clause
(iii) above on the property so acquired, or (z) Permitted Refinancing
Indebtedness with respect to any indebtedness referred to in clauses (r), (t)
and (v) above, PROVIDED that the restrictions contained in the agreements
governing such Permitted Refinancing Indebtedness are no more restrictive than
those contained in the agreements governing the Indebtedness being refinanced.

SECTION 4.9    INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED EQUITY.

               (a) The Company shall not, and shall not permit any of its
Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "INCUR") any
Indebtedness (including Acquired Indebtedness but excluding any Permitted
Indebtedness) and that the Company will not issue any Disqualified Stock and
will not permit any of its Restricted Subsidiaries to issue any shares of
preferred stock; PROVIDED, HOWEVER, that the Company may incur Indebtedness
(including Acquired Indebtedness) or issue shares of Disqualified Stock, and any
Restricted Subsidiary may incur Indebtedness (including Acquired Indebtedness),
if the Fixed Charge Coverage Ratio for the Company's most recently ended four
full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred
or such Disqualified Stock is issued would have been at least (i) 2.0 to 1.0 if
such date occurs on or after the Issue Date and on or prior to March 31, 1998,
or (ii) 2.25 to 1.0 if such date occurs after March 31, 1998, determined on a
pro forma basis (including a pro forma application of the net proceeds
therefrom), as if the additional Indebtedness had been incurred, or the
Disqualified Stock had been issued, as the case may be, at the beginning of such
four-quarter period.

               (b) The Company shall not, and shall not permit any Subsidiary
Guarantor to, directly or indirectly, in any event incur any Indebtedness that
by its terms (or by the terms of any agreement governing such Indebtedness) is
subordinated to any other Indebtedness of that Company or such Subsidiary
Guarantor, as the case may be, unless such Indebtedness is also by its terms (or
by the terms of any agreement governing such Indebtedness) made expressly
subordinate to the Notes or the Subsidiary Guarantee of such Subsidiary
Guarantor, as the case may be, to the same extent and in the same manner as such
Indebtedness is subordinated pursuant to subordination provisions that are most
favorable to the holders of any other Indebtedness of the Company or such
Subsidiary Guarantor, as the case may be.

        The foregoing provisions shall not apply to the incurrence of any of the
following Indebtedness (collectively, "PERMITTED INDEBTEDNESS"):

                      (i) Indebtedness (and any guarantee thereof) under the
        Working Line in an aggregate principal amount at any one time
        outstanding not to exceed the greater of (A) $35.0 million, less any

SECTION 4.10   ASSET SALES.

        The Company shall not, and shall not permit any Restricted Subsidiary
to, sell, issue, convey, transfer, lease or otherwise dispose of, to any Person
other than the Company or any of its Restricted Subsidiaries (including, without
limitation, by means of a sale-and-leaseback transaction or a merger or
consolidation) (collectively, for purposes of this Section 4.10, a "TRANSFER"),
directly or indirectly, in one or a series of related transactions, (a) any
Capital Stock of any Restricted Subsidiary held by the Company or any other
Restricted Subsidiary, (b) all or substantially all of the properties and assets
of any division or line of business of the Company or any of its Restricted
Subsidiaries, (c) any Event of Loss or (d) any other properties or assets of the
Company or any of its Restricted Subsidiaries other than transfers of cash, Cash
Equivalents, accounts receivable, or properties or assets in the ordinary course
of business; PROVIDED that the sale, lease, conveyance or other disposition of
all or substantially all of the properties or assets of the Company and its
Restricted Subsidiaries, taken as a whole, shall be governed by Sections 4.15
and/or 5.1 hereof and not by the provisions of this Section 4.10 (each of the
foregoing, an "ASSET SALE"), unless (i) the Company (or the Restricted
Subsidiary, as the case may be) receives consideration at the time of such Asset
Sale at least equal to the fair market value (evidenced by a resolution of the
Board of Directors set forth in an Officers' Certificate delivered to the
Trustee) of the assets or Equity Interests issued or sold or otherwise disposed
of and (ii) at least 75% of the consideration therefor received by the Company
or such Restricted Subsidiary is in the form of cash or Cash Equivalents;
PROVIDED that the amount of (x) any liabilities (as shown on the Company's or
such Restricted Subsidiary's most recent balance sheet) of the Company or any
Restricted Subsidiary (other than contingent liabilities and liabilities that
are Subordinated Indebtedness or otherwise by their terms subordinated to the
Notes or the Subsidiary Guarantees) that are assumed by the transferee of any
such assets pursuant to a novation agreement that releases the Company or such
Restricted Subsidiary from further liability and (y) any notes or other
obligations received by the Company or any such Restricted Subsidiary from such
transferee that are converted by the Company or such Restricted Subsidiary into
cash within 180 days of closing such Asset Sale (to the extent of the cash
received), shall be deemed to be cash for purposes of this clause (ii).

        Notwithstanding the foregoing, any of the following shall, not be deemed
an "Asset Sale": (i) any transfer of properties or assets to an Unrestricted
Subsidiary, if such transfer is permitted under Section 4.7 hereof; (ii) sales
of damaged, worn-out or obsolete equipment or assets that, in the Company's
reasonable judgment, are either (A) no longer used or (B) no
longer useful in the business 

                                       35
<PAGE>
of the Company or its Restricted Subsidiaries; (iii) any lease of any property
entered into in the ordinary course of business and with respect to which the
Company or any Restricted Subsidiary is the lessor, except any such lease that
provides for the acquisition of such property by the lessee during or at the end
of the term thereof for an amount that is less than the fair market value
thereof at the time the right to acquire such property occurs; (iv) any trade or
exchange by the Company or any Restricted Subsidiary of one or more workover
rigs for one or more workover rigs owned or held by another Person, PROVIDED
that (A) the Fair Market Value of the workover rig or rigs traded or exchanged
by the Company or such Restricted Subsidiary (including any cash or Cash
Equivalents, not to exceed 15% of such Fair Market Value, to be delivered by the
Company or such Restricted Subsidiary) is reasonably equivalent to the Fair
Market Value of the workover rig or rigs (together with any cash or Cash
Equivalents, not to exceed 15% of such Fair Market Value) to be received by the
Company or such Restricted Subsidiary and (B) such exchange is approved by a
majority of the Disinterested Directors of the Company; (v) sales of inventory
in the ordinary course of business of the Company and any Subsidiary consistent
with past practices; (vi) the issuance by the Company of its Capital Stock;
(vii) a Restricted Payment permitted under the terms of Section 4.7 hereof and
(viii) any transfers that, but for this clause (viii), would be Asset Sales, if
(A) the Company elects to designate such transfers as not constituting Asset
Sales and (B) after giving effect to such transfers, the aggregate Fair Market
Value of the properties or assets transferred in such transaction or any such
series of related transactions so designated by the Company does not exceed
$500,000.

        Within 365 days after the receipt of any Net Proceeds from any Asset
Sale, the Company may (i) apply all or any of the Net Proceeds therefrom to
repay Indebtedness (other than Subordinated Indebtedness) of the Company or any
Restricted Subsidiary, PROVIDED, in each case, that the related loan commitment
of any revolving credit facility or other borrowing (if any) is thereby
permanently reduced by the amount of such Indebtedness so repaid or (ii) invest
all or any part of the Net Proceeds thereof in properties and other capital
assets that replace the properties or other capital assets that were the subject
of such Asset Sale or in other properties or other capital assets that will be
used in the business of the Company and its Restricted Subsidiaries or in
entities engaged in such business, provided that in such latter instance such
entities become a Subsidiary Guarantor or Restricted Subsidiary, as applicable.
Pending the final application of any such Net Proceeds, the Company may
temporarily reduce borrowings under any revolving credit facility or otherwise
invest such Net Proceeds in any manner that is not prohibited by this Indenture.
Any Net Proceeds from Asset Sales that are not applied or invested as provided
in the first sentence of this paragraph shall be deemed to constitute "EXCESS
PROCEEDS". When the aggregate amount of Excess Proceeds equals or exceeds $15.0
million (the date of such occurrence being called the "ASSET SALE OFFER TRIGGER
DATE"), the Company shall make an offer to all Holders of Notes (an "ASSET SALE
OFFER") to purchase the maximum principal amount of Notes that may be purchased
out of the Excess Proceeds at an offer price in cash in an amount equal to 100%
of the principal amount thereof plus accrued and unpaid interest thereon to the
date of purchase in accordance with the procedures set forth in Section 3.9
hereof. To the extent that the aggregate amount of Notes tendered pursuant to an
Asset Sale Offer is less than the Excess Proceeds, the Company may use any
remaining Excess Proceeds for general corporate purposes. Upon completion of
such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

        The Company shall not permit any Restricted Subsidiary to enter into or
suffer to exist any agreement that would place any restriction of any kind
(other than pursuant to law or regulation) on the ability of the Company to make
an Asset Sale Offer following any Asset Sale. The Company shall comply with Rule
14e-1 under the Exchange Act, and any other securities laws and regulations

                                       36
<PAGE>
thereunder, if applicable, in the event that an Asset Sale occurs and the
Company is required to purchase Notes pursuant to this Section 4.10.

SECTION 4.11   TRANSACTIONS WITH AFFILIATES.

        The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, (a) sell, lease, transfer or otherwise dispose of any of its
properties, assets or securities to, (b) purchase or lease any property, assets
or securities from, (c) make any Investment in or (d) enter into or suffer to
exist any other transaction or series of related transactions with, or for the
benefit of, any Affiliate of the Company unless (i) such transaction or series
of transactions is on terms that are no less favorable to the Company or such
Restricted Subsidiary, as the case may be, than those that would be available in
a comparable arm's length transaction with an unrelated third party, (ii) with
respect to any one transaction or series of related transactions involving
aggregate payments in excess of $1.0 million, the Company delivers an Officers'
Certificate to the Trustee certifying that such transaction or series of related
transactions complies with clause (i) above and (iii) with respect to a
transaction or series of related transactions involving payments in excess of
$10.0 million, the Company delivers an Officers' Certificate to the Trustee
certifying that (A) such transaction or series of related transactions complies
with clause (i) above and (B) such transaction or series of related transactions
has been approved by a majority of the Disinterested Directors of the Company;
PROVIDED, HOWEVER, that the foregoing restriction shall not apply to (u) any
arrangements in effect on the Issue Date, (v) transactions between or among the
Company and its Wholly Owned Restricted Subsidiaries, (w) loans or advances to
officers, directors and employees of the Company or any Restricted Subsidiary
made in the ordinary course of business and consistent with past practices of
the Company and its Restricted Subsidiaries in an aggregate amount not to exceed
$1.0 million outstanding at any one time, (x) indemnities of officers, directors
and employees of the Company or any Restricted Subsidiary permitted by bylaw or
statutory provisions, (y) the payment of reasonable and customary regular fees
to directors of the Company or any of its Restricted Subsidiaries who are not
employees of the Company or any Affiliate and (z) the Company's employee
compensation and other benefit arrangements.

SECTION 4.12   LIENS.

        The Company shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, create, incur, assume, affirm or suffer to exist or
become effective any Lien of any kind, except for Permitted Liens, upon any of
their respective property or assets, whether now owned or acquired after the
Issue Date, or any income, profits or proceeds therefrom, to secure (i) any
Indebtedness of the Company or such Restricted Subsidiary (if it is not also a
Subsidiary Guarantor), unless prior to, or contemporaneously therewith, the
Notes are equally and ratably secured or (ii) any Indebtedness of any Subsidiary
Guarantor, unless prior to, or contemporaneously therewith, the Subsidiary
Guarantees are equally and ratably secured; PROVIDED, HOWEVER, that if such
Indebtedness is expressly subordinated to the Notes or the Subsidiary
Guarantees, the Lien securing such Indebtedness will be subordinated and junior
to the Lien securing the Notes or the Subsidiary Guarantees, as the case may be,
with the same relative priority as such Indebtedness has with respect to the
Notes or the Subsidiary Guarantees. The foregoing covenant shall not apply to
any Lien securing Acquired Indebtedness, provided that any such Lien extends
only to the property or assets that were subject to such Lien prior to the
related acquisition by the Company or such Restricted Subsidiary and was not
created, incurred or assumed in contemplation of such transaction.

Restricted Subsidiary of the Company to, transfer, convey, sell, or otherwise
dispose of any Capital Stock of any Wholly Owned Restricted Subsidiary of the
Company to any Person (other than the Company or a Wholly Owned Restricted
Subsidiary of the Company), unless (A) such transfer, conveyance, sale or other
disposition is of all the Capital Stock of such Wholly Owned Restricted
Subsidiary and (B) the cash Net Proceeds from such transfer, conveyance, sale or
other disposition are applied in accordance with Section 4.10 hereof and (ii)
will not permit any Wholly Owned Restricted Subsidiary of the Company to issue
any of its Equity Interests to any Person other than to the Company or a Wholly
Owned Restricted Subsidiary of the Company; except, in the case of both clauses
(i) and (ii) above, with respect to dispositions or issuances by a Wholly Owned
Restricted Subsidiary of the Company as contemplated in clauses (i) and (ii) of
the definition of "Wholly Owned Restricted Subsidiary" included in Section 1.1
hereof.

SECTION 4.14   SALE-AND-LEASEBACK TRANSACTIONS.

        The Company shall not, and shall not permit any of its Restricted
Subsidiaries to, enter into any sale-and-leaseback transaction; PROVIDED that
the Company or any Restricted Subsidiary, as applicable, may enter into a
sale-and-leaseback transaction if (i) the Company could have (A) incurred
Indebtedness in an amount equal to the Attributable Indebtedness relating to
such sale-and-leaseback transaction pursuant to the Fixed Charge Coverage Ratio
test set forth in Section 4.9(a) hereof and (B) incurred a Lien to secure such

in such sale-and-leaseback transaction is permitted by, and the Company applies

Notes shall have the right to require the Company to repurchase all or any part
(equal to $1,000 or an integral multiple thereof) of such Holder's Notes on a
Business Day (the "CHANGE OF CONTROL PAYMENT DATE") not more than 70 nor less
than 30 days following such Change of Control, pursuant to the offer described
below (the "CHANGE OF CONTROL OFFER") at an offer price in cash equal to 101% of
the aggregate principal amount thereof plus accrued and unpaid interest thereon
to the date of purchase (the "CHANGE OF CONTROL PAYMENT"). Within 30 days
following any Change of Control, the Company shall mail a notice to each Holder
describing the transaction or transactions that constitute the Change of Control
and offering to repurchase Notes pursuant to the procedures required by this
Section 4.15 and described in such notice. The Company shall comply with the

<PAGE>
of all Notes or portions thereof so tendered and (iii) deliver or cause to be
delivered to the Trustee the Notes so accepted, together with an Officers'
Certificate stating the aggregate principal amount of Notes or portions thereof
being purchased by the Company. The Paying Agent shall promptly mail or
otherwise deliver to each Holder of Notes so tendered the Change of Control
Payment for such Notes, and the Trustee shall promptly authenticate and mail (or
cause to be transferred by book entry) to each Holder a new Note equal in
principal amount to any unpurchased portion of the Notes surrendered, if any;
PROVIDED that each such new Note shall be in a principal amount of $1,000 or an
integral multiple thereof. The Company shall publicly announce the results of
the Change of Control Offer on or as soon as practicable after the Change of
Control Payment Date.

               (c) The Change of Control provisions described above shall be
applicable whether or not any other provisions of this Indenture are applicable.

               (d) The Company shall not be required to make a Change of Control
Offer upon a Change of Control if a third party makes the Change of Control
Offer in the manner, at the times and otherwise in compliance with the
requirements set forth in this Indenture applicable to a Change of Control Offer
made by the Company and purchases all Notes validly tendered and not withdrawn
under such Change of Control Offer.

        grace period or the occurrence of such acceleration, as the case may be,
        such Event of Default under this Section 6.1(v) and any consequential
        acceleration of the Notes shall be automatically rescinded, so long as
        such recision does not conflict with any judgment or decree;

                      (vi) a final judgment or final judgments for the payment
        of money are entered by a court or courts of competent jurisdiction
        against the Company or any of its Subsidiaries and such judgment or
        judgments remain unpaid and undischarged for a period (during which
        execution shall not be effectively stayed) of 60 consecutive days,
        provided that the aggregate of all such unpaid and undischarged
        judgments exceeds $5.0 million;

                      (vii) any Subsidiary Guarantee shall for any reason cease
        to be, or be asserted by the Company or any Subsidiary Guarantor, as
        applicable, not to be, in full force and effect (except pursuant to the
        release of any Subsidiary Guarantee in accordance with this Indenture);

                      (viii) the Company or any of its Restricted Subsidiaries
        that constitutes a Significant Subsidiary or any group of Restricted
        Subsidiaries that, taken together, would constitute a Significant

               constitutes a Significant Subsidiary or any group of Restricted

                             (B) appoints a Bankruptcy Custodian of the Company
               or any of its Restricted Subsidiaries that constitutes a

               Restricted Subsidiaries;

        and the order or decree remains unstayed and in effect for 60
        consecutive days.

SECTION 6.2    ACCELERATION.

        If any Event of Default (other than an Event of Default specified in
clause (viii) or (ix) of Section 6.1 hereof with respect to the Company or any
of its Restricted Subsidiaries that constitutes a Significant Subsidiary or any
group of Restricted Subsidiaries that, taken together, would constitute a
Significant Subsidiary) occurs and is continuing, the Trustee or the Holders of
at least 25% in aggregate principal amount of the then outstanding Notes may
declare all the Notes to be due and payable immediately. Upon any such
declaration, the Notes shall become due and payable immediately. Notwithstanding
the foregoing, if an Event of Default specified in clause (viii) or (ix) of
Section 6.1 hereof occurs with respect to the Company or any of its Restricted
Subsidiaries that constitutes a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken together, would constitute a Significant
Subsidiary, all outstanding Notes shall be due and payable immediately without
further action or notice.

        The Holders of a majority in aggregate principal amount of the then
outstanding Notes by written notice to the Trustee may on behalf of all of the
Holders waive any existing Default or Event of Default acceleration and its
consequences if the rescission would not conflict with any judgment or decree
and if all existing Events of Default (except nonpayment of principal, interest
or premium on the Notes) have been cured or waived.

SECTION 6.3    OTHER REMEDIES.

        If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy to collect the payment of principal, premium, if any, and
interest on the Notes or to enforce the performance of any provision of the
Notes or this Indenture.

        The Trustee may maintain a proceeding even if it does not possess any of
the Notes or does not produce any of them in the proceeding. A delay or omission
by the Trustee or any Holder of a Note in exercising any right or remedy
accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default. All remedies are
cumulative to the extent permitted by law.

                                       42
<PAGE>
SECTION 6.4    WAIVER OF PAST DEFAULTS.

        Holders of not less than a majority in aggregate principal amount of the
then outstanding Notes by notice to the Trustee may on behalf of the Holders of
all of the Notes waive an existing Default or Event of Default and its
consequences hereunder, except a continuing Default or Event of Default in the
payment of interest on, or the principal of, the Notes (including in connection
with an offer to purchase pursuant to Sections 3.7, 3.9, 4.10 or 4.15 hereof).
Upon any such waiver, such Default shall cease to exist, and any Event of
Default arising therefrom shall be deemed to have been cured for every purpose
of this Indenture; but no such waiver shall extend to any subsequent or other
Default or impair any right consequent thereon.

SECTION 6.5    CONTROL BY MAJORITY.

        Holders of a majority in aggregate principal amount of the then
outstanding Notes may direct the time, method and place of conducting any
proceeding for exercising any remedy available to the Trustee or exercising any
trust or power conferred on it. However, the Trustee may refuse to follow any
direction that conflicts with law or this Indenture that the Trustee determines
may be unduly prejudicial to the rights of other Holders of Notes or that may
involve the Trustee in personal liability.

SECTION 6.6    LIMITATION ON SUITS.

        A Holder of a Note may pursue a remedy with respect to this Indenture or
the Note only if:

                      (i) the Holder of a Note gives to the Trustee written
        notice of a continuing Event of Default;

                      (ii) the Holders of at least 25% in aggregate principal
        amount of the then outstanding Notes make a written request to the
        Trustee to pursue the remedy;

                      (iii) such Holder of a Notes or Holders of Notes offer
        and, if requested, provide to the Trustee indemnity satisfactory to the
        Trustee against any loss, liability or expense;

                      (iv) the Trustee does not comply with the request within
        60 days after receipt of the request and the offer and, if requested,
        the provision of indemnity; and

                      (v) during such 60-day period the Holders of a majority in
        aggregate principal amount of the then outstanding Notes do not give the
        Trustee a direction inconsistent with the request.

        A Holder of a Note may not use this Indenture to prejudice the rights of
another Holder of a Note or to obtain a preference or priority over another
Holder of a Note.

SECTION 6.7    RIGHTS OF HOLDERS OF NOTES TO RECEIVE PAYMENT.

        Notwithstanding any other provision of this Indenture, the right of any
Holder of a Note to receive payment of principal, premium, if any, and interest
on the Note, on or after the respective due dates expressed in the Note
(including in connection with an offer to purchase pursuant to Sections 3.7,

                                       43
<PAGE>
3.9, 4.10 or 4.15 hereof), or to bring suit for the enforcement of any such
payment on or after such respective dates, shall not be impaired or affected
without the consent of such Holder.

SECTION 6.8    COLLECTION SUIT BY TRUSTEE.

        If an Event of Default specified in Section 6.1(i) or (ii) occurs and is
continuing, the Trustee is authorized to recover judgment in its own name and as
trustee of an express trust against the Company for the whole amount of
principal of, premium, if any, and interest remaining unpaid on the Notes and
interest on overdue principal and, to the extent lawful, interest and such
further amount as shall be sufficient to cover the costs and expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

SECTION 6.9    TRUSTEE MAY FILE PROOFS OF CLAIM.

        The Trustee is authorized to file such proofs of claim and other papers
or documents as may be necessary or advisable in order to have the claims of the
Trustee (including any claim for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel) and the
Holders of the Notes allowed in any judicial proceedings relative to the Company
(or any other obligor upon the Notes), its creditors or its property and shall
be entitled and empowered to collect, receive and distribute any money or other
property payable or deliverable on any such claims and any custodian in any such
judicial proceeding is hereby authorized by each Holder to make such payments to
the Trustee, and in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee any amount due to
it for the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 7.7 hereof. To the extent that the payment of any such compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, and
any other amounts due the Trustee under Section 7.7 hereof out of the estate in
any such proceeding, shall be denied for any reason, payment of the same shall
be secured by a Lien on, and shall be paid out of, any and all distributions,
dividends, money, securities and other properties that the Holders may be
entitled to receive in such proceeding whether in liquidation or under any plan
of reorganization or arrangement or otherwise. Nothing herein contained shall be
deemed to authorize the Trustee to authorize or consent to or accept or adopt on
behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Notes or the rights of any Holder, or to authorize the
Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 6.10   PRIORITIES.

        If the Trustee collects any money pursuant to this Article 6, it shall
pay out the money in the following order:

                FIRST: to the Trustee, its agents and attorneys for amounts due
        under Section 7.7 hereof, including payment of all compensation, expense

        costs and expenses of collection;

                SECOND: to Holders of Notes for amounts due and unpaid on the
        Notes for principal, premium, if any, and interest, ratably, without
        preference or priority of any kind, according to the amounts due and
        payable on the Notes for principal, premium, if any, and interest,
        respectively; and

                                       44
<PAGE>
                THIRD: to the Company or to such party as a court of competent
        jurisdiction shall direct.

        The Trustee may fix a record date and payment date for any payment to
Holders of Notes pursuant to this Section 6.10.

SECTION 6.11   UNDERTAKING FOR COSTS.

        In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit of an undertaking to pay the costs of the suit, and the
court in its discretion may assess reasonable costs, including reasonable
attorneys' fees and expenses, against any party litigant in the suit, having due
regard for the merits and good faith of the claims or defenses made by the party
litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a
Holder of a Note pursuant to Section 6.6 hereof, or a suit by Holders of more
than 10% in aggregate principal amount of the then outstanding Notes.

SECTION 7.1    DUTIES OF TRUSTEE.

               (a) If an Event of Default has occurred and is continuing, the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in its exercise, as a
prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

               (b)    Except during the continuance of an Event of Default:

                      (i) the duties of the Trustee shall be determined solely
               by the express provisions of this Indenture and the Trustee need
               perform only those duties that are specifically set forth in this
               Indenture and no others, and no implied covenants or obligations
               shall be read into this Indenture against the Trustee; and

                      (ii) in the absence of bad faith on its part, the Trustee
               may conclusively rely, as to the truth of the statements and the
               correctness of the opinions expressed therein, upon certificates
               or opinions furnished to the Trustee and conforming to the
               requirements of this Indenture. However, in the case of any such
               certificates or opinions that by any provision hereof are
               specifically required to be furnished to the Trustee, the Trustee
               shall examine the certificates and opinions to determine whether
               or not they conform to the requirements of this Indenture.

               (c) The Trustee may not be relieved from liabilities for its own
negligent action, its own negligent failure to act, or its own willful
misconduct, except that:

<PAGE>
                      (ii) the Trustee shall not be liable for any error of
               judgment made in good faith by a Responsible Officer, unless it
               is proved that the Trustee was negligent in ascertaining the
               pertinent facts; and

                      (iii) the Trustee shall not be liable with respect to any
               action it takes or omits to take in good faith in accordance with
               a direction received by it pursuant to Section 6.5 hereof.

               (d) Whether or not therein expressly so provided, every provision
of this Indenture that in any way relates to the Trustee is subject to
paragraphs (a), (b) and (c) of this Section 7.1.

               (e) No provision of this Indenture shall require the Trustee to
expend or risk its own funds or incur any liability. The Trustee shall be under
no obligation to exercise any of its rights and powers under this Indenture at
the request of any Holders, unless such Holder shall have offered to the Trustee
security and indemnity satisfactory to it against any loss, liability or
expense.

               (f) The Trustee shall not be liable for interest on any money
received by it except as the Trustee may agree in writing with the Company.

require an Officers' Certificate or an Opinion of Counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in
reliance on such Officers' Certificate or Opinion of Counsel. The Trustee may
consult with counsel of its selection and the advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection from
liability in respect of any action taken, suffered or omitted by it hereunder in
good faith and in reliance thereon.

               (c) The Trustee may act through its attorneys and agents and
shall not be responsible for the misconduct or negligence of any agent appointed
with due care.

               (d) The Trustee shall not be liable for any action it takes or
omits to take in good faith that it believes to be authorized or within the
rights or powers conferred upon it by this Indenture.

demand, request, direction or notice from the Company shall be sufficient if
signed by an Officer of the Company.

               (f) The Trustee shall be under no obligation to exercise any of
the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders unless such Holders shall have offered to the Trustee

SECTION 7.3 INDIVIDUAL RIGHTS OF TRUSTEE.

        The Trustee in its individual or any other capacity may become the owner
or pledgee of Notes and may otherwise deal with the Company or any Affiliate of
the Compete with the same rights it would have if it were not Trustee. However,
in the event that the Trustee acquires any conflicting interest it must
eliminate such conflict within 90 days, apply to the Commission for permission
to continue as trustee or resign. Any Agent may do the same with like rights and
duties. The Trustee is also subject to Sections 7.10 and 7.11 hereof.

paid to the Company or upon the Company's direction under any provision of this
Indenture, it shall not be responsible for the use or application of any money
received by any Paying Agent other than the Trustee, and it shall not be
responsible for any statement or recital herein or any statement in the Notes or
any other document in connection with the sale of the Notes or pursuant to this
Indenture other than its certificate of authentication.

SECTION 7.5    NOTICE OF DEFAULTS.

        If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to Holders of Notes a notice of the
Default or Event of Default within 90 days after it occurs. Except in the case
of a Default or Event of Default in payment of principal of, premium, if any, or
interest on any Notes, the Trustee may withhold the notice if and so long as a
committee of its Responsible Officers in good faith determines that withholding
the notice is in the interests of the Holders of the Notes.

SECTION 7.6 REPORT BY TRUSTEE TO HOLDERS OF THE NOTES.

        Within 60 days after each May 15 beginning with the May 15 following the
date of this Indenture, and for so long as Notes remain outstanding, the Trustee
shall mail to the Holders of the Notes a brief report dated as of such reporting
date that complies with TIA ss. 313(a) (but if no event described in TIA ss.
313(a) has occurred within the 12 months preceding the reporting date, no report
need be transmitted). The Trustee also shall comply with TIA ss. 313(b)(2) and
ss. 313(b)(1). The Trustee shall also transmit by mail all reports as required
by TIA ss. 313(c).

        A copy of each report at the time of its mailing to the Holders of Notes
shall be mailed to the Company and filed with the Commission and each stock
exchange on which the Notes are listed in accordance with TIA ss. 313(d). The
Company shall promptly notify the Trustee when the Notes are listed on any stock
exchange.

SECTION 7.7    COMPENSATION AND INDEMNITY.

        The Company shall pay to the Trustee from time to time such compensation
as shall be agreed between the Company and the Trustee for its acceptance of
this Indenture and services hereunder. The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust. The Company
shall reimburse the Trustee promptly upon request for all reasonable
disbursements,

                                       47
<PAGE>
advances and expenses incurred or made by it in addition to the compensation for
its services. Such expenses shall include the reasonable compensation,
disbursements and expenses of the Trustee's agents and counsel.

        The Company shall indemnify each of the Trustee and any successor
Trustee against any and all losses, liabilities, damages, claims or expenses,
including taxes (other than taxes based on the income of the Trustee), incurred
by it arising out of or in connection with the acceptance or administration of
its duties under this Indenture, including the costs and expenses of enforcing
this Indenture against the Company (including this Section 7.7) and defending
itself against any claim (whether asserted by the Company or any Holder or any
other person) or liability in connection with the exercise or performance of any
of its powers or duties hereunder, except to the extent any such loss, liability

its obligations hereunder. The Company shall defend the claim and the Trustee

Trustee shall have a Lien prior to the Notes on all money or property held or
collected by the Trustee, except that held in trust to pay principal, premium,
if any, and interest on particular Notes. Such Lien shall survive the
satisfaction and discharge of this Indenture.

Default specified in Section 6.1(viii) or (ix) hereof occurs, the expenses and
the compensation for the services (including the fees and expenses of its agents
and counsel) are intended to constitute expenses of administration under any
Bankruptcy Law. The Trustee shall also be entitled to receive compensation for
extraordinary services in default administration.

        The Trustee shall comply with the provisions of TIA ss. 313 (b)(2) to
the extent applicable.

SECTION 7.8    REPLACEMENT OF TRUSTEE.

Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.8.

        The Trustee may resign in writing at any time and be discharged from the
trust hereby created by so notifying the Company. The Holders of Notes of a
majority in aggregate principal amount of the then outstanding Notes may remove

Trustee or its property; or

               (d) the Trustee becomes incapable of acting.

office of Trustee for any reason, the Company shall promptly appoint a successor
Trustee. Within one year after the successor Trustee takes office, the Holders
of a majority in aggregate principal amount of the then outstanding Notes may
appoint a successor Trustee to replace the successor Trustee appointed by the
Company.

        If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
Holders of Notes of at least 10% in aggregate principal amount of the then
outstanding Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

        If the Trustee, after written request by any Holder of a Note who has
been a Holder of a Note for at least six months, fails to comply with Section
7.10 hereof, such Holder of a Note may petition any court of competent
jurisdiction for the removal of the Trustee and the appointment of a successor
Trustee.

        A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to the Company. Thereupon, the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. The successor Trustee shall mail a notice of its
succession to Holders of the Notes. The retiring Trustee shall promptly transfer
all property held by it as Trustee to the successor Trustee, provided all sums

subject to the satisfaction of the conditions set forth in Section 8.4 hereof,
be deemed to have been discharged from its obligations with respect to all
outstanding Notes on the date the conditions set forth below are satisfied
(hereinafter, "LEGAL DEFEASANCE"). For this purpose, Legal Defeasance means that
the Company shall be deemed to have paid and discharged the entire Indebtedness
represented by the outstanding Notes, which shall thereafter be deemed to be
"outstanding" only for the purposes of Section 8.5 hereof and the other Sections
of this Indenture referred to in clauses (i) and (ii) below, and the Company and
each Subsidiary Guarantor shall be deemed to have satisfied all of its other
obligations under such Notes or Subsidiary Guarantee and this Indenture (and the

instruments acknowledging the same), except for the following provisions, which
shall survive until otherwise terminated or discharged hereunder: (i) the rights
of Holders of outstanding Notes to receive solely from the trust fund described

SECTION 8.3    COVENANT DEFEASANCE.

        Upon the Company's exercise under Section 8.1 hereof of the option
applicable to this Section 8.3, the Company shall, subject to the satisfaction

obligations under the covenants contained in Sections 4.5, 4.7, 4.8, 4.9, 4.10,
4.11, 4.12, 4.13, 4.14, 4.15 and 4.16 hereof and Article 10 hereof with respect
to the outstanding Notes on and after the date the conditions set forth below
are satisfied (hereinafter, "COVENANT DEFEASANCE"), and the Notes shall
thereafter be deemed not "outstanding" for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed
"outstanding" for all other purposes 

                                       50

for accounting purposes). For this purpose, Covenant Defeasance means that, with
respect to the outstanding Notes, the Company and any Subsidiary Guarantor may
omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or
indirectly, by reason of any reference elsewhere herein to any such covenant or
by reason of any reference in any such covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a Default
or an Event of Default under Section 6.1 hereof, but, except as specified above,
the remainder of this Indenture and such Notes shall be unaffected thereby. In
addition, upon the Company's exercise under Section 8.1 hereof of the option
applicable to this Section 8.3 hereof, subject to the satisfaction of the
conditions set forth in Section 8.4 hereof, Sections 6.1(v) and 6.1(vii) hereof
shall not constitute Events of Default.

SECTION 8.4    CONDITIONS TO LEGAL OR COVENANT DEFEASANCE.

        The following shall be the conditions to the application of either
Sections 8.2 or 8.3 hereof to the outstanding Notes:

        In order to exercise either Legal Defeasance or Covenant Defeasance:

               (a) the Company must irrevocably deposit with the Trustee, in
trust, for the benefit of the Holders, cash in United States dollars,
non-callable Government Securities, or a combination thereof, in such amounts as
will be sufficient, in the opinion of a nationally recognized firm of
independent public accountants, to pay the principal of, premium, if any, and
interest on the outstanding Notes on the stated date for payment thereof or on
the applicable redemption date, as the case may be, and the Company must specify
whether the Notes are being defeased to maturity or to a particular redemption
date;

               (b) in the case of an election under Section 8.2 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that (i) the Company has
received from, or there has been published by, the Internal Revenue Service a
ruling or (ii) since the date of this Indenture, there has been a change in the
applicable federal income tax law, in either case to the effect that, and based
thereon such Opinion of Counsel shall confirm that, the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Legal Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Legal Defeasance had not occurred;

               (c) in the case of an election under Section 8.3 hereof, the
Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that the Holders of the
outstanding Notes will not recognize income, gain or loss for federal income tax
purposes as a result of such Covenant Defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as
would have been the case if such Covenant Defeasance had not occurred;

               (d) no Default or Event of Default shall have occurred and be
continuing on the date of such deposit (other than a Default or Event of Default
resulting from the incurrence of Indebtedness all or a portion of the proceeds
of which will be used to defease the Notes pursuant to this Article 8

                                       51
<PAGE>
concurrently with such incurrence) or insofar as Section 6.1(viii) or 6.1(ix)
hereof is concerned, at any time in the period ending on the 91st day after the
date of deposit;

               (e) such Legal Defeasance or Covenant Defeasance shall not result
in a breach or violation of, or constitute a default under, any material
agreement or instrument (other than this Indenture) to which the Company or any
of its Subsidiaries is a party or by which the Company or any of its
Subsidiaries is bound;

               (f) the Company shall have delivered to the Trustee an Opinion of
Counsel to the effect that, as of the date such opinion, (i) the trust funds
will not be subject to rights of holders of Indebtedness other than the Notes
and (ii) assuming no intervening bankruptcy of the Company between the date of
deposit and the 91st day following the deposit (assuming no Holder of Notes is
an insider of the Company) or the day following the end of such other preference
period in effect at the time of such opinion (assuming a Holder of Notes is an
insider of the Company), as applicable, following the deposit, the trust funds
will not be subject to the effects of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally under any
applicable United States or state law;

               (g) the Company shall have delivered to the Trustee an Officers'
Certificate stating that the deposit was not made by the Company with the intent
of preferring the Holders of Notes over any other creditors of the Company or
any Subsidiary Guarantor with the intent of defeating, hindering, delaying or
defrauding creditors of the Company, or any Subsidiary Guarantor or others; and

               (h) the Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, which, taken together, state that all
conditions precedent provided for or relating to the Legal Defeasance or the
Covenant Defeasance have been complied with.

SECTION 8.5    DEPOSITED MONEY AND GOVERNMENT SECURITIES TO BE HELD IN
               TRUST; OTHER MISCELLANEOUS PROVISIONS.

        Subject to Section 8.6 hereof, all money and non-callable Government
Securities (including the proceeds thereof) deposited with the Trustee (or other
qualifying trustee, collectively for purposes of this Section 8.5, the
"TRUSTEE") pursuant to Section 8.4 hereof in respect of the outstanding Notes
shall be held in trust and applied by the Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or
through any Paying Agent (including the Company acting as Paying Agent) as the
Trustee may determine, to the Holders of such Notes of all sums due and to
become due thereon in respect of principal, premium, if any, and interest, but
such money need not be segregated from other funds except to the extent required
by law.

        The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the cash or non-callable Government
Securities deposited pursuant to Section 8.4 hereof or the principal and
interest received in respect thereof other than any such tax, fee or other
charge which by law is for the account of the Holders of the outstanding Notes.

        Anything in this Article 8 to the contrary notwithstanding, the Trustee
shall deliver or pay to the Company from time to time upon the request of the
Company any money or non-callable Government Securities held by it as provided
in Section 8.4 hereof that, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee (which may be the opinion delivered under Section
8.4(a) hereof), are in excess of the amount thereof 

                                       52
<PAGE>
that would then be required to be deposited to effect an equivalent Legal
Defeasance or Covenant Defeasance.

SECTION 8.6    REPAYMENT TO THE COMPANY.

        Subject to the applicable escheat and abandoned property laws, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of, premium, if any, or interest on any
Note and remaining unclaimed for two years after such principal, and premium, if
any, or interest has become due and payable shall be paid to the Company on its
request or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Notes shall thereafter, as a secured creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; PROVIDED, HOWEVER, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in The New York Times and
The Wall Street Journal (national edition), notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than
30 days from the date of such notification or publication, any unclaimed balance
of such money then remaining will be repaid to the Company.

SECTION 8.7    REINSTATEMENT.

        If the Trustee or Paying Agent is unable to apply any United States
dollars or non-callable Government Securities in accordance with Section 8.5
hereof by reason of any order or judgment of any court or governmental authority
enjoining, restraining or otherwise prohibiting such application, then the
Company's obligations under this Indenture and the Notes shall be revived and
reinstated as though no deposit had occurred pursuant to Sections 8.2 or 8.3
hereof until such time as the Trustee or Paying Agent is permitted to apply all
such money in accordance with Section 8.5 hereof; PROVIDED, HOWEVER, that, if
the Company makes any payment of principal of, premium, if any, or interest on
any Note following the reinstatement of its obligations, the Company shall be
subrogated to the rights of the Holders of such Notes to receive such payment
from the money held by the Trustee or Paying Agent.

SECTION 9.2    WITH CONSENT OF HOLDERS OF NOTES.

        Except as provided below in this Section 9.2, the Company and the
Trustee may amend or supplement this Indenture, the Subsidiary Guarantees or the

principal amount of the Notes then outstanding (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange
offer for, Notes) and, subject to Sections 6.4 and 6.7 hereof, any existing
Default or Event of Default (other than a Default or Event of Default in the
payment of the principal of, premium, if any, or interest on the Notes, except a
payment default resulting from an acceleration that has been rescinded) or
compliance with any provision of this Indenture or the Notes may be waived with
the consent of the Holders of a majority in aggregate principal amount of the

purchase of, tender offer or exchange offer for Notes).

        Upon the request of the Company accompanied by a resolution of its Board

Trustee of the consent of the Holders of Notes as aforesaid, and 

                                       54
<PAGE>
upon receipt by the Trustee of the documents described in Section 9.6 hereof,
the Trustee shall join with the Company and the Subsidiary Guarantors in the
execution of such amended or supplemental Indenture unless such amended or
supplemental Indenture affects the Trustee's own rights, duties or immunities
under this Indenture or otherwise, in which case the Trustee may in its
discretion, but shall not be obligated to, enter into such amended or
supplemental Indenture.

        Subject to Sections 6.4 and 6.7 hereof, the Holders of a majority in
aggregate principal amount of the Notes then outstanding may waive compliance in
a particular instance by the Company and the Subsidiary Guarantors with any
provision of this Indenture or the Notes. However, without the consent of each
Holder affected, an amendment or waiver may not (with respect to any Notes held
by a non-consenting Holder):

                                Holders must consent to an amendment, supplement

                                the Notes (except as provided below with respect
                                to Sections 3.9, 4.10 and 4.15 hereof);

                        (iii)   reduce the rate of or change the time for
                                payment of interest, including default interest,
                                on any Note;

                        (iv)    waive a Default or Event of Default in the
                                payment of principal of or premium, if any, or
                                interest on the Notes (except a rescission of
                                acceleration of the Notes by the Holders of at
                                least a majority in aggregate principal amount
                                of the then outstanding Notes and a waiver of
                                the payment default that resulted from such
                                acceleration);

                        (v)     make any Note payable in money other than that
                                stated in the Notes;

                        (vi)    make any change in the provisions of this
                                Indenture relating to waivers of past Defaults
                                or the rights of Holders of Notes to receive
                                payments of principal of or premium, if any, or
                                interest on the Notes;

                        (vii)   waive a redemption payment with respect to any
                                Note (other than a payment required by Sections
                                4.10 or 4.15 hereof);

                        (viii)  alter the ranking of the Notes relative to other
                                Indebtedness of the Company; or

                        (ix)    make any change in the foregoing amendment and
                                waiver provisions.

        In addition, without the consent of Holders of not less than 66-2/3% in
aggregate principal amount of the Notes then outstanding, no such amendment,
supplement or waiver may amend, change or modify the obligation of the Company
to make and consummate a Change of Control Offer in the event of a Change of
Control or make and consummate an Asset Sale Offer with respect to any Asset
Sale or modify any of the provisions or definitions with respect thereto.

                                       55
<PAGE>
        It shall not be necessary for the consent of the Holders of Notes under
this Section 9.2 to approve the particular form of any proposed amendment or
waiver, but it shall be sufficient if such consent approves the substance
thereof.

        After an amendment, supplement or waiver under this Section 9.2 becomes
effective, the Company shall mail to the Holders of Notes affected thereby a
notice briefly describing the amendment, supplement or waiver. Any failure of
the Company to mail such notice, or any defect therein, shall not, however, in
any way impair or affect the validity of any such amended or supplemental
Indenture or waiver.

SECTION 9.3    COMPLIANCE WITH TRUST INDENTURE ACT.

        Every amendment or supplement to this Indenture or the Notes shall be
set forth in a amended or supplemental Indenture that complies with the TIA as
then in effect.

SECTION 9.4    REVOCATION AND EFFECT OF CONSENTS.

        Until an amendment, supplement or waiver becomes effective, a consent to
it by a Holder of a Note is a continuing consent by the Holder of a Note and
every subsequent Holder of a Note or portion of a Note that evidences the same
debt as the consenting Holder's Note, even if notation of the consent is not
made on any Note. However, any such Holder of a Note or subsequent Holder of a
Note may revoke the consent as to its Note if the Trustee receives written
notice of revocation before the date the waiver, supplement or amendment becomes
effective. An amendment, supplement or waiver becomes effective in accordance
with its terms and thereafter binds every Holder.

SECTION 9.5    NOTATION ON OR EXCHANGE OF NOTES.

        The Trustee may place an appropriate notation about an amendment,
supplement or waiver on any Note thereafter authenticated. The Company in
exchange for all Notes may issue and the Trustee shall authenticate new Notes
that reflect the amendment, supplement or waiver.

        Failure to make the appropriate notation or issue a new Note shall not
affect the validity and effect of such amendment, supplement or waiver.

SECTION 9.6    TRUSTEE TO SIGN AMENDMENT ETC.

stating that the execution of such amended or supplemental Indenture is

                              SUBSIDIARY GUARANTEES

SECTION 10.1   SUBSIDIARY GUARANTEES.

               (a) The Subsidiary Guarantors and each Subsidiary of the Company
that in accordance with Section 10.2 hereof is required to guarantee the
obligations of the Company under the Notes and this Indenture hereby jointly and
severally and unconditionally guarantees, on a senior basis (each such guarantee
being a "SUBSIDIARY GUARANTEE"), to each Holder of a Note authenticated and
delivered by the Trustee irrespective of the validity or enforceability of this
Indenture, the Notes or the obligations of the Company under this Indenture or
the Notes, that: (i) the principal of, premium, if any, and interest on the
Notes shall be paid in full when due, whether at the maturity or interest
payment or mandatory redemption date, by acceleration, call for redemption or
otherwise, and interest on the overdue principal and interest, if any, of the
Notes and all other obligations of the Company to the Holders or the Trustee
under this Indenture or the Notes shall be promptly paid in full or performed,
all in accordance with the terms of this Indenture and the Notes and (ii) in
case of any extension of time of payment or renewal of any Notes or any of such
other obligations, they shall be paid in full when due or performed in
accordance with the terms of the extension or renewal, whether at maturity, by
acceleration or otherwise. Failing payment when due of any amount so guaranteed
for whatever reason, each Subsidiary Guarantor shall be obligated to pay the
same whether or not such failure to pay has become an Event of Default that
could cause acceleration pursuant to Section 6.2 hereof. Each Subsidiary
Guarantor agrees that this is a guarantee of payment not a guarantee of
collection.

               (b) Each Subsidiary Guarantor hereby agrees that its obligations
with regard to its Subsidiary Guarantee shall be unconditional, irrespective of
the validity or enforceability of the Notes or the obligations of the Company
under this Indenture, the absence of any action to enforce the same, the
recovery of any judgment against the Company or any other obligor with respect
to this Indenture, the Notes or the obligations of the Company under this
Indenture or the Notes, any action to enforce the same or any other
circumstances (other than complete performance) that might otherwise constitute
a legal or equitable discharge or defense of a Subsidiary Guarantor. Each
Subsidiary Guarantor further, to the extent permitted by law, waives and
relinquishes all claims, rights and remedies accorded by applicable law to
guarantors and agrees not to assert or take advantage of any such claims, rights
or remedies, including but not limited to: (i) any right to require the Trustee,
the Holders or the Company (each, a "BENEFITTED PARTY") to proceed against the
Company or any other Person or to proceed against or exhaust any security held
by a Benefitted Party at any time or to pursue any other remedy in any
Benefitted Party's power before proceeding against such Subsidiary Guarantor;
(ii) the defense of the statute of limitations in any action hereunder or in any
action for the collection of any Indebtedness or the performance of any
obligation hereby guaranteed; (iii) any defense that may arise by reason of the
incapacity, lack of authority, death or disability of any other Person or the
failure of a Benefitted Party to file or enforce a claim against the estate (in
administration, bankruptcy or any other proceeding) of any other Person; (iv)
demand, protest and notice of any kind including but not limited to notice of
the existence, creation or incurring of any new or additional Indebtedness or
obligation or of any action or non-action on the part of such Subsidiary
Guarantor, the Company, any Benefitted Party, any creditor of such Subsidiary
Guarantor, the Company or on the part of any other Person whomsoever in
connection with any Indebtedness or Obligations hereby guaranteed; (v) any
defense based upon an election of remedies by a Benefitted Party, including but
not limited to an election to proceed against such Subsidiary Guarantor for
reimbursement; (vi) any defense based upon any statute or rule of law that
provides that 

                                       57
<PAGE>
the obligation of a surety must be neither larger in amount nor in other
respects more burdensome than that of the principal; (vii) any defense arising
because of a Benefitted Party's election, in any proceeding instituted under any
Bankruptcy Law, of the application of Section 1111(b)(2) under the Bankruptcy
Law; (viii) any defense based on any borrowing or grant of a security interest
under Section 364 under the Bankruptcy Law or (ix) any right to require a
proceeding first against the Company, protest, notice and all demands
whatsoever. Each Subsidiary Guarantor hereby covenants that its Subsidiary
Guarantee will not be discharged except by complete performance of all of the
obligations contained in its Subsidiary Guarantee, the Notes and this Indenture.

               (c) If any Holder or the Trustee is required by any court or
otherwise to return to either the Company or any Subsidiary Guarantor, or any
custodian, trustee, or similar official acting in relation to either the Company
or such Subsidiary Guarantor, any amount paid by the Company or such Subsidiary
Guarantor to the Trustee or such Holder, the applicable Subsidiary Guarantee, to
the extent theretofore discharged, shall be reinstated in full force and effect.
Each Subsidiary Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed
hereby until payment in full of all obligations guaranteed hereby.

               (d) Each Subsidiary Guarantor further agrees that, as between
such Subsidiary Guarantor, on the one hand, and the Holders and the Trustee, on
the other hand, (i) the maturity of the obligations guaranteed hereby may be
accelerated as provided in Section 6.2 hereof for the purposes of this
Subsidiary Guarantee, notwithstanding any stay, injunction or other prohibition
preventing such acceleration as to the Company or any other obligor on the Notes
of the obligations guaranteed hereby and (ii) in the event of any declaration of
acceleration of those obligations as provided in Section 6.2 hereof, those
obligations (whether or not due and payable) will forthwith become due and
payable by such Subsidiary Guarantor for the purpose of this Subsidiary
Guarantee.

SECTION 10.2   ADDITIONAL SUBSIDIARY GUARANTEES.

               (a) If, after the Issue Date, (i) the Company or any of its
Restricted Subsidiaries shall (A) transfer or cause to be transferred, any
assets, businesses, divisions, real property or equipment having a fair market
or book value in excess of $1.0 million to any Restricted Subsidiary that is not
a Subsidiary Guarantor or (B) make any Investment having an aggregate fair
market or book value in excess of $1.0 million in any Restricted Subsidiary that
is not a Subsidiary Guarantor or (ii) any Restricted Subsidiary that is not a
Subsidiary Guarantor (A) shall provide a guarantee under the Credit Facility or
(B) shall own any assets or properties having an aggregate fair market or book
value in excess of $1.0 million, then the Company shall cause such Restricted
Subsidiary to execute and deliver a supplemental indenture to this Indenture
agreeing to be bound by its terms applicable to a Subsidiary Guarantor and
providing for a Subsidiary Guarantee of the Notes by such Restricted Subsidiary,
in accordance with the terms of this Indenture.

               (b) The Company shall not permit any of its Restricted
Subsidiaries, other than a Subsidiary Guarantor, directly or indirectly, to (i)
incur, guarantee or secure through the granting of Liens the payment of any
Indebtedness of the Company or (ii) pledge any intercompany notes representing
obligations of any of its Restricted Subsidiaries to secure the payment of any
Indebtedness of the Company, in each case, unless the Company shall cause such
Restricted Subsidiary to execute a Subsidiary Guarantee and deliver an Opinion
of Counsel in advance in accordance with the terms of this Indenture.

                                       58
<PAGE>
SECTION 10.3   LIMITATION OF SUBSIDIARY GUARANTORS' LIABILITY.

               (a) Each Subsidiary Guarantor and by its acceptance hereof, each
beneficiary hereof, hereby confirm that it is its intention that the Subsidiary
Guarantee by such Subsidiary Guarantor not constitute a fraudulent transfer or
conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance
Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to
the extent applicable to any of the Subsidiary Guarantees. To effectuate the
foregoing intention, each such person hereby irrevocably agrees that the
obligations of such Subsidiary Guarantor under its Subsidiary Guarantee under
this Article 10 shall be limited to the maximum amount as will, after giving
effect to all other contingent and fixed liabilities of such Subsidiary
Guarantor and after giving effect to any collections from or payments made by or
on behalf of any other Subsidiary Guarantor in respect of the obligations of
such other Subsidiary Guarantor under its Subsidiary Guarantee or pursuant to
its contribution obligations under this Indenture, result in the obligations of
such Subsidiary Guarantor under the Subsidiary Guarantee not constituting a
fraudulent conveyance or fraudulent transfer under federal or state law.

               (b) For purposes of such limitations and the applicable
fraudulent conveyance laws, any indebtedness of a Subsidiary Guarantor incurred
from time to time pursuant to the Credit Facility and secured by a perfected
Lien on the assets of such Subsidiary Guarantor (assuming, for purposes of such
determination, that the incurrence of any such indebtedness and the granting of
any such security interest did not violate any such fraudulent conveyance laws)
shall be deemed, to the extent of the value of the assets subject to such Lien,
to have been incurred prior to the incurrence by such Subsidiary Guarantor of
liability under its Subsidiary Guarantee.

               (c) Each beneficiary under the Subsidiary Guarantees, by
accepting the benefits hereof, confirms its intention that, in the event of a
bankruptcy, reorganization or other similar proceeding of the Company or any
Subsidiary Guarantor in which concurrent claims are made upon such Subsidiary
Guarantor hereunder, to the extent such claims will not be fully satisfied, each
such claimant with a valid claim against the Company shall be entitled to a
ratable share of all payments by such Subsidiary Guarantor in respect of such
concurrent claims.

SECTION 10.4   SUBSIDIARY GUARANTORS MAY CONSOLIDATE ETC., ON CERTAIN TERMS.

               (a) No Subsidiary Guarantor may consolidate with or merge with or
into (whether or not such Subsidiary Guarantor is the surviving Person) another
Person (other than the Company or another Subsidiary Guarantor), whether or not
affiliated with such Subsidiary Guarantor, unless (i) subject to the provisions
of the following paragraph, the Person formed by or surviving any such
consolidation or merger (if other than such Subsidiary Guarantor) shall execute
and deliver a supplemental indenture to this Indenture agreeing to be bound by
its terms applicable to a Subsidiary Guarantor and providing for a Subsidiary
Guarantee of the Notes by such Person, in accordance with the terms of this
Indenture; (ii) immediately after giving effect to such transaction, no Default
or Event of Default exists; (iii) such Subsidiary Guarantor, or any Person
formed by or surviving any such consolidation or merger, would have Consolidated
Net Worth (immediately after giving effect to such transaction), equal to or
greater than the Consolidated Net Worth of such Subsidiary Guarantor immediately
preceding the transaction; (iv) the Company would be permitted by virtue of the
Company's pro forma Fixed Charge Coverage Ratio, immediately after giving effect
to such transaction, to incur at least $1.00 of additional Indebtedness pursuant
to the Fixed Charge Coverage Ratio test set forth in Section 4.9(a) hereof and
(v) such transaction does not violate any of the covenants contained in Articles
4 and 5 hereof. In 

                                       59
<PAGE>
connection with any consolidation or merger contemplated by this provision, the
Subsidiary Guarantor shall deliver, or cause to be delivered, to the Trustee, in
form and substance reasonably satisfactory to the Trustee, an Officers'
Certificate and an Opinion of Counsel, each stating that such consolidation or
merger and the supplemental indenture in respect thereto comply with this
provision and that all conditions precedent in this Indenture provided for
relating to such transaction or transactions have been complied with.

               (b) Notwithstanding the foregoing, (i) a Subsidiary Guarantor may
consolidate with or merge with or into the Company, provided that the surviving
corporation (if other than the Company) shall expressly assume by supplemental
indenture complying with the requirements of this Indenture, the due and
punctual payment of the principal of, premium, if any, and interest on all of
the Notes, and the due and punctual performance and observance of all the
covenants and conditions of this Indenture to be performed by the Company and
(ii) a Subsidiary Guarantor may consolidate with or merge with or into any other
Subsidiary Guarantor.

SECTION 10.5   RELEASES OF SUBSIDIARY GUARANTORS.

        In the event of (i) the designation of any Subsidiary Guarantor as an
Unrestricted Subsidiary or (ii) a sale or other disposition of all or
substantially all of the properties or assets of any Subsidiary Guarantor to a
third party or an Unrestricted Subsidiary, by way of merger, consolidation or
otherwise, or a sale or other disposition of all of the capital stock of any
Subsidiary Guarantor, in either case, in a transaction or manner that does not
violate any of the covenants or other provision of this Indenture, then such
Subsidiary Guarantor (in the event of such a designation or a sale or other
disposition, by way of such a merger, consolidation or otherwise, of all of the
capital stock of such Subsidiary Guarantor) or the Person acquiring the property
(in the event of a sale or other disposition of all or substantially all of the
assets of such Subsidiary Guarantor) will be released from and relieved of any
obligations under this Indenture and its Subsidiary Guarantee, PROVIDED that any
Net Proceeds of such sale or other disposition are applied in accordance with
Section 4.10 hereof and PROVIDED, FURTHER, HOWEVER, that any such termination
shall occur only to the extent that all obligations of such Subsidiary Guarantor
under all of its guarantees of, and under all of its pledges of assets or other
security interests that secure, any other Indebtedness of the Company or its
Restricted Subsidiaries shall also terminate upon such release, sale or
disposition.

SECTION 10.6   "TRUSTEE" TO INCLUDE PAYING AGENT.

        In case at any time any Paying Agent other than the Trustee shall have
been appointed by the Company and be then acting hereunder, the term "Trustee"
as used in this Article 10 shall in such case (unless the context shall
otherwise require) be construed as extending to and including such Paying Agent
within its meaning as fully and for all intents and purposes as if such Paying
Agent were named in this Article 10 in place of the Trustee.

SECTION 10.7   CONTRIBUTION.

        In order to provide for just and equitable contribution among the
Subsidiary Guarantors, the Subsidiary Guarantors agree, INTER SE, that in the
event any payment or distribution is made by any Subsidiary Guarantor (a
"FUNDING GUARANTOR") under a Subsidiary Guarantee, such Funding Guarantor shall
be entitled to a contribution from all other Subsidiary Guarantors in a pro rata
amount based on the Adjusted Net Assets (as defined below) of each Subsidiary
Guarantor (including the Funding Guarantor) 

                                       60
<PAGE>
for all payments, damages and expenses incurred by that Funding Guarantor in
discharging the Company's obligations with respect to the Notes or any other
Subsidiary Guarantor's obligations with respect to such Subsidiary Guarantee.
"ADJUSTED NET ASSETS" of such Subsidiary Guarantor at any date shall mean the
lesser of the amount by which (x) the fair value of the property of such
Subsidiary Guarantor exceeds the total amount of liabilities, including, without
limitation, contingent liabilities, but excluding liabilities under the
Subsidiary Guarantee of such Subsidiary Guarantor at such date and (y) the
present fair salable value of the assets of such Subsidiary Guarantor at such
date exceeds the amount that will be required to pay the probable liability of
such Subsidiary Guarantor on its debts (after giving effect to all other fixed
and contingent liabilities incurred or assumed on such date and after giving
effect to any collection from any subsidiary of such Subsidiary Guarantor in
respect of the obligations of such subsidiary under the Subsidiary Guarantees),
excluding debt in respect of the Subsidiary Guarantees, as they become absolute
and matured.

SECTION 10.8   EXECUTION OF SUBSIDIARY GUARANTEES.

        To evidence its guarantee to each Holder of Notes, each of the
Subsidiary Guarantors hereby agree to execute its Subsidiary Guarantee in
substantially the form of Exhibit A recited to be endorsed on each Note ordered
to be authenticated and delivered by the Trustee. Each Subsidiary Guarantor
hereby agrees that its Subsidiary Guarantee set forth in Section 10.1 hereof
shall remain in full force and effect notwithstanding any failure to endorse on
each Note a notation of such Subsidiary Guarantee. Each such Subsidiary
Guarantee shall be signed on behalf of each Subsidiary Guarantor by one Officer
of such Subsidiary Guarantor who shall have been duly authorized by all
requisite corporate actions, and the delivery of such Note by the Trustee, after
the authentication thereof hereunder, shall constitute due delivery of such
Subsidiary Guarantee on behalf of such Subsidiary Guarantor. Such signatures
upon the Subsidiary Guarantee may be by manual or facsimile signature of such
Officer and may be imprinted or otherwise reproduced on the Subsidiary
Guarantee, and in case any such Officer who shall have signed the Subsidiary
Guarantee shall cease to be such Officer before the Note on which such
Subsidiary Guarantee is endorsed shall have been authenticated and delivered by
the Trustee or disposed of by the Company, such Note nevertheless may be
authenticated and delivered or disposed of as though the person who signed the
Subsidiary Guarantee had not ceased to be such officer of the Subsidiary
Guarantor.

                          9-3/8% SENIOR NOTES DUE 2007

        Unless and until it is exchanged in whole or in part for Notes in
definitive form, this Note may not be transferred except as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository or by the Depository or any
such nominee to a successor Depository or a nominee of such successor
Depository. Unless this certificate is presented by an authorized representative
of The Depository Trust Company (55 Water Street, New York, New York) ("DTC"),
to the Company or its agent for registration of transfer, exchange or payment,
and any certificate issued is registered in the name of Cede & Co. or such other
name as may be requested by an authorized representative of DTC (and any payment
is made to Cede & Co. or such other entity as may be requested by an authorized
representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR
OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner
hereof, Cede & Co, has an interest herein.(1)

        Capitalized terms used herein shall have the meanings assigned to them
in the Indenture referred to below unless otherwise indicated.

        1. INTEREST. Dawson Production Services, Inc., a Texas corporation (the
"COMPANY"), promises to pay interest on the principal amount of this Note at
9-3/8% per annum from February 20, 1997, until maturity. The Company shall pay
interest semi-annually on February 1 and August 1 of each year, or if any such
day is not a Business Day, on the next succeeding Business Day (each, an
"INTEREST PAYMENT DATE"). Interest on the Notes shall accrue from the most
recent date to which interest has been paid or, if no interest has been paid,
from the date of issuance; PROVIDED that the first Interest Payment Date shall
be August 1, 1997. The Company shall pay interest (including post-petition
interest in any proceeding under any Bankruptcy Law) on overdue principal and
premium, if any, from time to time on demand at a rate that is 1% per annum in
excess of the rate then in effect; it shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on overdue
installments of interest (without regard to any applicable grace periods) from
time to time on demand at the same rate to the extent lawful. Interest will be
computed on the basis of a 360-day year of twelve 30-day months.

        2. METHOD OF PAYMENT. The Company shall pay interest on the Notes
(except defaulted interest) to the Persons who are registered Holders of Notes
at the close of business on the January 15 or July 15 next preceding the
Interest Payment Date, even if such Notes are canceled after such record date
and on or before such Interest Payment Date, except as provided in Section 2.12
of the Indenture with respect to defaulted interest. The Notes will be payable
as to principal, premium and interest at the office or agency of the Company
maintained for such purpose within or without the City and State of New York,
or, at the option of the Company, payment of interest may be made by check
mailed to the Holders at their addresses set forth in the register of Holders,
and provided that payment by wire transfer of immediately available funds will
be required with respect to principal of, and interest and premium on, all
Global Notes and all other Notes the Holders of which shall have provided
written wire transfer instructions to the Company or the Paying Agent at least
10 Business Days prior to the applicable 
- ------------
(1) This paragraph should be included only in the Note if issued in global form.

                                      A-2

payment date. Such payment shall be in such coin or currency of the United
States of America as at the time of payment is legal tender for payment of
public and private debts.

        3. PAYING AGENT AND REGISTRAR. Initially, U.S. Trust Company of Texas,
N.A., the Trustee under the Indenture, will act as Paying Agent and Registrar.
The Company may change any Paying Agent or Registrar without notice to any
Holder. The Company or any of its Subsidiaries may act in any such capacity.

        4. INDENTURE AND SUBSIDIARY GUARANTEES. The Company issued the Notes
under an Indenture dated as of February 20, 1997 (the "INDENTURE"), among the
Company, the Subsidiary Guarantors and the Trustee. The terms of the Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code ss.ss.
77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred
to the Indenture and such Act for a statement of such terms. The Notes are
obligations of the Company limited to $140.0 million in aggregate principal
amount. Payment on each Note is guaranteed on a senior basis, jointly and
severally, by the Subsidiary Guarantors pursuant to Article 10 of the Indenture.

        5.     OPTIONAL REDEMPTION.

               (a) Except as set forth in subparagraph (b) of this Paragraph 5,
the Company shall not have the option to redeem the Notes prior to February 1,
2002. Thereafter, the Company shall have the option to redeem the Notes, in
whole or in part, upon not less than 30 nor more than 60 days' written notice,
at the redemption prices (expressed as percentages of principal amount) set
forth below, plus accrued and unpaid interest thereon, if any, to the applicable
redemption date, if redeemed during the 12-month period beginning on February 1
of each of the years indicated below:

            YEAR                                             PERCENTAGE

           2002..........................................     104.6875%
           2003..........................................     103.1250%
           2004..........................................     101.5625%
           2005 and thereafter...........................     100.0000%

               (b) Notwithstanding the provisions of subparagraph (a) of this
Paragraph 5, at any time on or prior to February 1, 2000, the Company may redeem
up to an aggregate of $49.0 million principal amount of Notes at a redemption
price of 109.375% of the principal amount thereof, plus accrued and unpaid
interest thereon to the redemption date, with the net proceeds of a Public
Equity Offering; PROVIDED that at least $91.0 million in aggregate principal
amount of Notes remain outstanding immediately after the occurrence of such
redemption; and, PROVIDED, FURTHER, that such redemption shall occur within 60
days of the date of the closing of such Public Equity Offering.

        6. MANDATORY REDEMPTION. The Company shall not be required to make
mandatory redemption payments or sinking fund payments with respect to the
Notes.

<PAGE>
        7.     REPURCHASE AT OPTION OF HOLDER.

               (a) If there is a Change of Control, the Company shall be
required to make an offer (a "CHANGE OF CONTROL OFFER") to repurchase all or any
part (equal to $1,000 or an integral multiple thereof) of each Holder's Notes at
a purchase price equal to 101% of the aggregate principal amount thereof plus
accrued and any unpaid interest thereon, if any, to the Change of Control
Payment Date (as hereinafter defined) (the "CHANGE OF CONTROL PAYMENT"). Within
30 days of the occurrence of a Change of Control, the Company shall notify the
Trustee in writing of such proposed occurrence and shall make a Change of
Control Offer. Within 30 days following the occurrence of a Change of Control,
the Company shall mail a notice to each Holder setting forth the procedures
governing the Change of Control Offer as required by the Indenture.

               (b) If the Company or a Restricted Subsidiary consummates any
Asset Sales, within 10 days following each Asset Sale Trigger Date, the Company
shall commence an offer to all Holders of Notes (an "ASSET SALE OFFER") pursuant
to Section 3.9 of the Indenture to purchase the maximum principal amount of
Notes that may be purchased out of the Excess Proceeds at an offer price in cash
in an amount equal to 100% of the principal amount thereof plus accrued and
unpaid interest thereon, if any, to the Asset Sale Offer Purchase Date in
accordance with the procedures set forth in the Indenture. To the extent that
the aggregate amount of Notes tendered pursuant to an Asset Sale Offer is less
than the Excess Proceeds, the Company (or such Subsidiary) may use such excess
for general corporate purposes. Holders of Notes that are the subject of an
offer to purchase will receive an Asset Sale Offer from the Company prior to any
related purchase date and may elect to have such Notes purchased by completing
the form entitled "Option of Holder to Elect Purchase" on the reverse of the
Notes.

        8. NOTICE OF REDEMPTION. Notice of redemption shall be mailed at least
30 days but not more than 60 days before a redemption date to each Holder whose
Notes are to be redeemed at its registered address. Notes in denominations
larger than $1,000 may be redeemed in part but only in whole multiples of
$1,000, unless all of the Notes held by a Holder are to be redeemed. On and
after the redemption date interest ceases to accrue on Notes or portions thereof
called for redemption.

        9. DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $1,000 and integral multiples of $1,000. The
transfer of Notes may be registered and Notes may be exchanged as provided in
the Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company need not exchange or register the
transfer of any Note or portion of a Note selected for redemption, except for
the unredeemed portion of any Note being redeemed in part. Also, it need not
exchange or register the transfer of any Notes for a period of 15 days before a
selection of Notes to be redeemed or during the period between a record date and
the corresponding Interest Payment Date.

        10. PERSONS DEEMED OWNERS. The registered Holder of a Note may be
treated as its owner for all purposes.

        11. AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the
Indenture or the Notes may be amended or supplemented with the consent of the
Holders of at least a majority in aggregate principal amount of the then
outstanding Notes, and any existing default or compliance with any provision of
the Indenture or the Notes may be waived with the consent of the Holders of a
majority in aggregate principal amount of the then outstanding Notes. Without
the consent of any Holder of a 

                                      A-4
<PAGE>
Note, the Indenture or the Notes may be amended or supplemented to cure any
ambiguity, defect or inconsistency, to provide for uncertificated Notes in
addition to or in place of certificated Notes, to provide for the assumption of
the Company's obligations to Holders of the Notes in case of a merger or
consolidation, to make any change that would provide any additional rights or
benefits to the Holders of the Notes or that does not adversely affect the legal
rights under the Indenture of any such Holder, to secure the Notes, to add or
release any Subsidiary Guarantor pursuant to the terms of the Indenture or to
comply with the requirements of the Commission in order to effect or maintain
the qualification of the Indenture under the TIA.

        12. DEFAULTS AND REMEDIES. Events of Default include: (i) default for 30
days in the payment when due of interest on the Notes; (ii) default in payment
when due of principal of or premium, if any, on the Notes when the same becomes
due and payable at maturity, upon redemption (including in connection with an
offer to purchase) or otherwise, (iii) failure by the Company to comply with
Section 4.10, 4.15 or 5.1 of the Indenture; (iv) failure by the Company for 45
days after notice to the Company by the Trustee or the Holders of at least 25%
in aggregate principal amount of the Notes then outstanding to comply with
certain other agreements in the Indenture or the Notes; (v) default under
certain other agreements relating to Indebtedness of the Company, which default
(A) is caused by a failure to pay principal of or premium, if any, or interest
on such Indebtedness prior to the expiration of the grace period provided in
such Indebtedness on the date of such default (a "PAYMENT DEFAULT") or (B)
results in the acceleration of such Indebtedness prior to its express maturity
and, in each case, the principal amount of any such Indebtedness, together with
the principal amount of any other such Indebtedness under which there has been a
Payment Default or the maturity of which has been so accelerated, aggregates
$5.0 million or more for any single Indebtedness or a total of $10.0 million or
more for all such Indebtedness and PROVIDED, FURTHER, that if any such default
is cured or waived or any such acceleration rescinded, or such Indebtedness is
repaid, within a period of 10 days from the continuation of such default beyond
the applicable grace period or the occurrence of such acceleration, as the case
may be, such Event of Default under the Indenture and any consequential
acceleration of the Notes shall be automatically rescinded, so long as such
recision does not conflict with any judgment or decree; (vi) certain final
judgments for the payment of money that remain undischarged for a period of 60
days; (vii) any Subsidiary Guarantee shall for any reason cease to be, or be
asserted by the Company or any Restricted Subsidiary that is a Guarantor, as
applicable, not to be, in full force and effect (except pursuant to the release
of any Subsidiary Guarantee in accordance with the Indenture) and (viii) certain
events of bankruptcy or insolvency with respect to the Company or any of its
Restricted Subsidiaries that constitutes a Significant Subsidiary or any group
of Restricted Subsidiaries that, taken together, would constitute a Significant
Subsidiary. If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in aggregate principal amount of the then outstanding
Notes may declare all the Notes to be due and payable immediately.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency with respect to the Company, any
Restricted Subsidiary that constitutes a Significant Subsidiary or any group of
Restricted Subsidiaries that, taken together, would constitute a Significant
Subsidiary, all outstanding Notes will become due and payable without further
action or notice. Holders may not enforce the Indenture or the Notes except as
provided in the Indenture. Subject to certain limitations, Holders of a majority
in principal amount of the then outstanding Notes may direct the Trustee in its
exercise of any trust or power. The Trustee may withhold from Holders of the
Notes notice of any continuing Default or Event of Default (except a Default or
Event of Default relating to the payment of principal or interest) if it
determines that withholding notice is in their interest. The Holders of a
majority in aggregate principal amount of the Notes then outstanding by notice
to the Trustee may on behalf of the Holders of all of the Notes waive any
existing Default or Event of Default and its consequences under the Indenture
except a continuing 

                                      A-5
<PAGE>
Default or Event of Default in the payment of interest on, or the principal of,
the Notes. The Company is required to deliver to the Trustee annually a
statement regarding compliance with the Indenture, and the Company is required
upon becoming aware of any Default or Event of Default, to deliver to the
Trustee a statement specifying such Default or Event of Default.

        13. TRUSTEE DEALINGS WITH THE COMPANY. The Trustee, in its individual or
any other capacity, may make loans to, accept deposits from, and perform
services for the Company or its Affiliates, and may otherwise deal with the
Company or its Affiliates, as if it were not the Trustee.

        14. NO RECOURSE AGAINST OTHERS. No past, present or future director,
officer, employee, incorporator or shareholder of the Company or any Subsidiary
Guarantor, as such, shall have any liability for any obligations of the Company
or such Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary
Guarantees, as the case may be, or for any claim based on, in respect of, or by
reason of, such obligations or their creation. Each Holder by accepting a Note
waives and releases all such liability. The waiver and release are part of the
consideration for the issuance of the Notes and the Subsidiary Guarantees.

        15. AUTHENTICATION. This Note shall not be valid until authenticated by
the manual signature of the Trustee.

        16. ABBREVIATIONS. Customary abbreviations may be used in the name of a
Holder or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship
and not as tenants in common), CUST (= Custodian) and U/G/M/A (= Uniform Gifts
to Minors Act).

        17. CUSIP NUMBERS. Pursuant to a recommendation promulgated by the
Committee on Uniform Security Identification Procedures, the Company has caused
CUSIP numbers to be printed on the Notes and the Trustee may use CUSIP numbers
in notices of redemption as a convenience to Holders. No representation is made
as to the accuracy of such numbers either as printed on the Notes or as
contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

        The Company shall furnish to any Holder upon written request and without
charge a copy of the Indenture. Requests may be made to:

          [FORM OF NOTATION ON NOTE RELATING TO SUBSIDIARY GUARANTEES]

        Each of the Subsidiary Guarantors under the Indenture (the "INDENTURE")
referred to in the Note upon which this notation is endorsed, has
unconditionally guaranteed the obligations of the Company under the Notes and
the Indenture, jointly and severally (each such guarantee being a "SUBSIDIARY
GUARANTEE"), to each Holder of a Note authenticated and delivered by the Trustee
irrespective of the validity or enforceability of the Indenture, the Notes or
the obligations of the Company under the Indenture or the Notes, that: (i) the
principal of, premium, if any, and interest on the Notes shall be paid in full
when due, whether at the maturity or interest payment or mandatory redemption
date, by acceleration, call for redemption or otherwise, and interest on the
overdue principal and interest, if any, of the Notes and all other obligations
of the Company to the Holders or the Trustee under the Indenture or the Notes
shall be promptly paid in full or performed, all in accordance with the terms of
the Indenture and the Notes and (ii) in case of any extension of time of payment
or renewal of any Notes or any of such other obligations, they shall be paid in
full when due or performed in accordance with the terms of the extension or
renewal, whether at maturity, by acceleration or otherwise. Failing payment when
due of any amount so guaranteed for whatever reason, each Subsidiary Guarantor
shall be obligated to pay the same whether or not such failure to pay has become
an Event of Default that could cause acceleration pursuant to Section 6.2 of the
Indenture. Each Subsidiary Guarantor agrees that this is a guarantee of payment,
not a guarantee of collection. Capitalized terms used herein have the meanings
assigned to them in the Indenture unless otherwise indicated, and the
obligations of the Subsidiary Guarantors pursuant to the Subsidiary Guarantees
are subject to the terms of the Indenture, to which reference is hereby made for
the precise terms thereof. The obligations of each Subsidiary Guarantor to the
Holders of Notes and to the Trustee pursuant to the Subsidiary Guarantee and the
Indenture are expressly set forth, and are senior unsecured obligations of each
such Subsidiary Guarantor to the extent and in the manner provided, in Article
10 of the Indenture, and may be released or limited under certain circumstances.
Reference is hereby made to such Indenture for the precise terms of the
Subsidiary Guarantee therein made.

        The Subsidiary Guarantees shall not be valid or obligatory for any
purpose until the certificate of authentication on the Note on which the
Subsidiary Guarantees are noted shall have been executed by the Trustee under
the Indenture by the manual signature of one of its authorized officers.

        By each of the following, and any other Subsidiary Guarantor as may be
added or substituted from time to time, as Subsidiary Guarantors:

                                   THE CREDITS

        SECTION 2.1 COMMITMENT TO LEND. From time to time prior to February
20th, 1999, so long as there is no Default or Event of Default under this

Day before each Borrowing or the issuance of each Letter of Credit requested
hereunder, Borrower shall give the Bank the following:

                                       2
<PAGE>
            (1)   for each Borrowing, notice (a "Consolidated Borrowing Base
                  Certificate") in the form attached hereto as Exhibit B
                  specifying the amount of such Borrowing;

            (2)   for each Letter of Credit, a Consolidated Borrowing Base
                  Certificate and a notice (a "Letter of Credit Information
                  Form") in the form attached hereto as Exhibit C specifying the
                  terms of the requested Letter of Credit.

        (c) Not later than 2:00 P.M. (San Antonio time) on the date of each
Borrowing, unless the Bank determines that any applicable condition precedent

its deposit account established with the Bank.

        SECTION 2.3   NOTES.

        (a) The Loans of the Bank shall be evidenced by a Note to the Bank and a
Note to each Purchaser described in Section 8.7(d) in the amount of the
Commitment held by each.

        (b) Each reference in this Agreement to the "Notes" of the Bank shall be
deemed to refer to and include any or all of the Notes referred to in the
preceding clause (a), as the context may require.

        (c) Bank shall record on its books, and prior to any transfer of the
Notes shall endorse on the schedule forming a part thereof, appropriate
notations to evidence the date and amount of the Loans made and the date and
amount of each payment of principal made by Borrower with respect thereto;
provided that the failure of the Bank to make any such recordation or
endorsement shall not affect the obligations of Borrower or the Bank hereunder
or under any other Loan Document. The Bank is hereby irrevocably authorized by
Borrower so to endorse the Notes and to attach to and make a part of the Notes a
continuation of any such schedule as and when required.

        SECTION 2.4 INTEREST RATES AND PAYMENT.

        (a) The Loans shall bear interest on the outstanding principal amount
thereof at a rate per annum equal to whichever of the following rates as shall
be selected by Borrower in its Selection of Interest Rate Form given to Bank at
the time of the initial Borrowing: (i) the Prime Rate the Bank may charge from
time to time, or (ii) the sum of the Applicable Margin PLUS the applicable Wall
Street Journal London Interbank Offered Rate, but never more than the Maximum
Rate. The interest rate so selected by Borrower shall continue to be effective
as to all Loans until the date of maturity unless no less than three Business
Days prior to the end of any month before maturity, Borrower shall change its
selection on one or more occasions by submitting to the Bank a new Selection of
interest Rate Form. Any new interest rate so selected shall become effective as
to all Loans as of the first day of the following month, and such new interest
rate shall continue to be effective until the date of maturity unless again
changed by Borrower in accordance with the preceding sentence of this Section
2.4(a). Accrued, unpaid interest on the outstanding principal of the Loans shall
be due and payable 

                                       3
<PAGE>
monthly as it accrues on the first day of each month for the Loans. Any
principal of and, to the extent permitted by Law, interest on the Loans which
has become due and payable shall bear interest on the unpaid portion thereof,
payable on demand, for each day from such due date and until paid, at the
Default Rate.

        (b) The Bank shall determine the interest rate applicable to the Loans
hereunder and each fee hereunder. Interest for all Loans and all fees shall be
computed on the basis of a year of 360 days, in each case for the actual number
of days elapsed (including the first day but excluding the last day), except
that, if use of a 360-day year would result in a rate in excess of the Maximum
Rate, such computation will be made on the basis of a year consisting of 365 or
366 days, as appropriate. Each determination by the Bank of an interest rate or
fee hereunder shall be conclusive and binding in the absence of manifest error.

        (c) Notwithstanding the foregoing, if at any time the applicable
contractual rate of interest provided for herein (without reference to the
Maximum Rate limitation) exceeds the Maximum Rate, then the rate of interest on
the Loans or other Obligation shall be limited to the Maximum Rate during such
time, and at all times thereafter (including periods during which any or all of
such applicable contractual rates of interest have fallen below the Maximum
Rate), the interest rate on the Loans or other Obligation shall be the Maximum
Rate, or if there is no Maximum Rate in effect, the Agreed Maximum Rate, until
the total amount of interest accrued on the Loans or other Obligation equals the
amount of interest which would have accrued thereon if the applicable
contractual rate of interest (without reference to the Maximum Rate limitation)
had at all times been in effect; but in no event shall the aggregate interest
payable or paid during the period beginning on the date the initial Loan is made
until the Obligations are paid in full exceed an amount equal to interest at the
Maximum Rate, so long as the Maximum Rate shall be applicable to this Agreement
and the transactions contemplated hereby. If at maturity or final payment of the
Notes or other Obligations, as applicable, the total amount of interest paid or
accrued on the Notes or other Obligations under the foregoing provisions is less
than the total amount of interest which would have been paid or accrued if the
applicable contractual rate of interest provided for herein had at all times
been in effect, then the Borrower agrees, to the fullest extent permitted by
Law, to pay an amount equal to the difference between (i) the lesser of (A) the
amount of interest which would have been paid or accrued on the Notes or other
Obligations, as applicable, if the Maximum Rate had at all times been in effect
and (B)the amount of interest which would have been paid or accrued on the Notes
or other Obligations, as applicable, if a rate per annum equal to the applicable
contractual rate of interest provided for herein had at all times been in
effect, and (ii) the amount of interest paid or accrued in accordance with the
other provisions of the Notes or other Obligations, as applicable.

        (d) The payment of interest (or any amount deemed to be interest) on the
Notes and on any other Obligation shall, in all respects regarding each Loan
Document, be subject to the provisions of Section 8.8.

                                       4
<PAGE>
        (e) Unless the maturity of the Notes shall have sooner accrued, the
outstanding principal balance of the Notes and any accrued, unpaid interest
shall be finally and fully payable on February 20, 1999.

        SECTION 2.5 COMMITMENT, LOAN AND LETTER OF CREDIT FEES. Subject to
Section 8.8 the Borrower shall pay to the Bank:

        (a) On the Closing Date, a Commitment fee in the amount of$125,000.00;

        (b) A Loan fee equal to .15% (15 basis points) per annum on the average
daily unused amount of the Commitment during the term thereof; with such Loan
fee to be payable quarterly in arrears on the 15th day of May, August, November
and February of each year commencing May 15, 1997, upon the Bank's delivery to
the Borrower of a detailed statement thereof for the preceding calendar quarter,
and

        (c) A Letter of Credit fee equal to the greater of (i) $300.00 for each
Letter of Credit issued during the term of the Commitment, or (ii) 1.5% per
annum on the average daily face amount of each Letter of Credit issued during
such term; with such Letter of Credit fee to be payable upon execution and
delivery to Bank of an Application and Agreement for Standby Letter of Credit in
form and substance satisfactory to the Bank.

        SECTION 2.6 MANDATORY PREPAYMENTS. If at any time the aggregate
principal amount of all Loans outstanding and the face amount of all outstanding
Letters of Credit exceeds the lesser of (i) the Consolidated Borrowing Base, or
(ii) the sum of $50,000,000.00, the Borrower shall immediately prepay the Loans
in an amount at least equal to such excess of Loans and Letters of Credit over
the lesser of "(i)" or "(ii)" above. All such mandatory prepayments shall be
accompanied by, and the Borrower shall pay, interest thereon which has accrued
until the date of payment thereof.

        SECTION 2.7 OPTIONAL PREPAYMENTS. The Borrower may, upon notice to the
Bank given not later than 1:00 P.M. (San Antonio time) on the date of prepayment
of the Loans, prepay (without premium or penalty) the Loans in whole at any
time, or from time to time in part. Such notice shall specify the date and
amount of prepayment. The payment amount specified in such notice shall be due
and payable on the date specified therein, together with accrued interest
thereon and other fees and expenses due and owing by such Borrower to the date
of prepayment.

        SECTION 2.8 GENERAL PROVISIONS AS TO PAYMENTS. The Borrower shall make
each payment of principal of and interest on the Loans and each payment of fees
or any other Obligations of the Borrower, in U.S. dollars, not later than 1:00
P.M. (San Antonio time) on the date when due (it being understood that interest
shall accrue and be payable for such date on any amounts which are paid after
1:00 P.M. (San Antonio time)), in immediately available funds, without
deduction, setoff or counterclaim to the Bank at the Domestic Lending Office of
the Bank set forth in Annex A. Whenever any payment of principal of or interest
shall be due on a day which is not a Business Day, the date for payment thereof
shall be extended to the next succeeding Business Day unless such 

                                       5
<PAGE>
Business Day falls in another calendar month, in which case the date for payment
thereof shall be the immediately preceding Business Day. Whenever any payment of
any other Obligations shall be due on a day which is not a Business Day, the
date for payment thereof shall be extended to the next succeeding Business Day.
If the date for any payment of principal is extended as provided above or by
operation of law or otherwise, interest thereon shall be payable for such
extended time.

        SECTION 2.9 PROCEEDS OF LOANS. The proceeds of the Loans shall be used
by Borrower to (i) support Accounts Receivable; (ii) fund Letters of Credit for
up to$10,000,000.00 issued by the Bank as a part of its Commitment, and (iii)
provide for certain of the Companies' working capital needs.

and as more specifically provided in the assignment and assumption agreement in
the form of Exhibit H attached hereto and made a part hereof for all purposes.
Purchaser shall for all purposes be a bank party to this Agreement and have 50%
of the rights and obligations of the Bank under this Agreement to the same
extent as if Purchaser were an original party hereto with 50% of the Commitment
asset forth in the assignment and assumption agreement, and Bank shall be
released from a corresponding 50% of its Commitment, rights and obligations
under this Agreement. No further consent or action by Borrower or the Bank shall
be required. However, pursuant to the terms of this Agreement and the assignment
and assumption agreement, all payment, reporting and notification obligations of
Borrower hereunder shall be satisfied by Borrower delivering all such payments,
reports and notices to transferor Bank in accordance with the terms of this
Agreement. No such payments, reports or notices need be delivered by Borrower to
Purchaser, but shall be delivered to transferor Bank by Purchaser pursuant to
the terms of the assignment and assumption agreement. All notices to be
delivered by Bank to Borrower hereunder shall also be delivered by transferor
Bank to Borrower pursuant to the terms of this Agreement and the assignment and
assumption agreement.

        (e) The Borrower authorizes the Bank to disclose to any Participant and
the Purchaser (each a "Transferee") and any prospective Participant any and all
financial information in the Bank's possession concerning the Borrower which has
been delivered to the Bank by or on behalf of it 

                                       29
<PAGE>
pursuant to this Agreement or which has been delivered to the Bank by them in
connection with the Bank's credit evaluation prior to entering into this
Agreement.

        (f) No Transferee shall be entitled to receive any greater payment under
this Agreement than the transferor Bank would have been entitled to receive with
respect to the rights assigned.

        (g) Notwithstanding any other provisions of this Section 8.7, no
transfer or assignment of the interests or obligations of the Bank hereunder or
any grant of participations therein shall be permitted if such transfer,
assignment or grant would require any Borrower to file a registration statement
with the Securities and Exchange Commission or to qualify the Loans under
the"Blue Sky" laws of any state.

        (h) Each person that becomes a Bank pursuant to an assignment permitted
by Section 8.7(d) will, upon its becoming party to this Agreement, represent
that it is a Qualified Bank, and that it will make or acquire Loans only for its
own account in the ordinary course of its business; provided, however, that
subject to the preceding provisions of this Section 8.7, the disposition of any
promissory notes or other evidences of or interests in Obligations held by it
shall at all times be within its exclusive control.

        SECTION 8.8 MAXIMUM INTEREST RATE. It is the intent of the parties
hereto that each of the Bank and the Borrower in the execution, delivery and
performance of all Loan Documents, the transactions provided for therein and
contemplated thereby, and all matters incidental and related thereto and arising
therefrom, shall comply and conform strictly with Applicable Law from time to
time in effect. In furtherance thereof, the Bank and the Borrower stipulate and
agree that none of the terms and provisions contained in, or pertaining to, the
Loan Documents shall ever be construed to create a contract to pay for the use
or forbearance or detention of money with interest at a rate or in an amount in
excess of the Maximum Rate or maximum amount of interest permitted or allowed to
be contracted for, charged, received, taken or reserved under said Laws. For
purposes of each Loan Document, (i) "interest" shall include the aggregate of
all amounts which constitute or are deemed to constitute interest under the Laws
of the State of Texas or, to the extent they may apply, the Laws of the United
States of America, that are contracted for, chargeable, receivable(whether
received or deemed to have been received), taken or reserved under each such
document, and (ii) all computations of the maximum amount of interest permitted
or allowed under Applicable Law will be made on the basis of the actual number
of days elapsed over a 365 or 366 day year, whichever is applicable. Neither the
Borrower nor any other person shall ever be required to pay unearned interest
on, or with respect to any of, the Loan Documents and shall never be required to
pay interest on, or with respect to any of, the Loan Documents at a rate or in
an amount in excess of the Maximum Rate or maximum amount of interest that may
be lawfully contracted for, charged, received, taken or reserved under
Applicable Law, AND THE PROVISIONS OF THIS PARAGRAPH SHALL CONTROL OVER ALL
OTHER PROVISIONS OF THE LOAN DOCUMENTS. If the effective rate or amount of
interest which would otherwise be payable under the Loan Documents would exceed
the Maximum Rate or maximum amount of interest the Bank or any other holder of
any Note or other Obligations is allowed by Applicable Law to charge, contract
for, take, reserve or receive, or in the event the Bank or any 

                                       30
<PAGE>
holder of any Note or other Obligations shall charge, contract for, take,
reserve or receive monies that are deemed to constitute interest which would, in
the absence of this provision, increase the effective rate or amount of interest
payable under the Loan Documents to a rate or amount in excess of that permitted
or allowed to be charged, contracted for, taken, reserved or received under
Applicable Law then in effect, then the principal amount of such Note or other
Obligations or the amount of interest which would otherwise be payable
thereunder shall be payable at, or reduced to, as applicable, the maximum amount
allowed pursuant to the then applicable indicated (weekly) rate ceiling referred
to herein above at the definition of the term Applicable Law, or if no such
ceiling is then in effect, as authorized and allowed under said Laws as now or
hereafter construed by the courts having jurisdiction, and all such monies so
charged, contracted, for, received, taken or reserved that are deemed to
constitute interest in excess of the Maximum Rate or maximum amount of interest
permitted by Applicable Law shall be immediately returned or credited to the
account of such Borrower upon such determination.

        SECTION 8.9 GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS AGREEMENT,
THE NOTE AND EACH OTHER LOAN DOCUMENT (INCLUDING ITS AND THEIR VALIDITY,
ENFORCEABILITY AND INTERPRETATION) SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF TEXAS (WITHOUT REGARD TO ANY
CONFLICTS OF LAW PRINCIPLES) AND TO THE EXTENT CONTROLLING, THE FEDERAL LAWS OF
THE USA; PROVIDED THAT (I) THE PROVISION OF CHAPTER 15 OF THE TEXAS CREDIT CODE
(VERNON'S TEXAS CIVIL STATUTES, ARTICLE 5069-15.01 ET SEQ.) ARE EXPRESSLY
DECLARED BY THE PARTIES NOT TO BE APPLICABLE TO ANY LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED BY ANY OF THEM, AND (II) THE LAWS OF THE STATE OF
TEXAS AND/OR THE UNITED STATES OF AMERICA SHALL NOT LIMIT THE AMOUNT OR RATE OF
INTEREST WHICH THE HOLDER OF ANY NOTE MAY CONTRACT FOR, CHARGE, RECEIVE,
COLLECT, TAKE, RESERVE AND/OR APPLY IF OTHER APPLICABLE LAWS PERMIT AT ANY TIME
A HIGHER AMOUNT OR RATE. THE PARTIES EXPRESSLY ACKNOWLEDGE THAT (Y) THEY INTEND
THAT THIS AGREEMENT AND EACH OTHER LOAN DOCUMENT SHALL BE GOVERNED BY THE
PROVISIONS (INCLUDING, WITHOUT LIMITATION, THE RIGHT OF THE PARTIES TO SELECT
THE GOVERNING LAW) OF THE UNIFORM COMMERCIAL CODE AND NOT BY COMMON LAW AND (Z)
THE STATE OF TEXAS BEARS A REASONABLE RELATIONSHIP TO THIS TRANSACTION AND NO
OTHER STATE HAS A MATERIALLY GREATER INTEREST IN THIS TRANSACTION THAN THE STATE
OF TEXAS. EACH BORROWER HEREBY SUBMITS TO THE NONEXCLUSIVE JURISDICTION OF THE
UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF TEXAS (SAN ANTONIO
DIVISION) AND OF ANY TEXAS STATE COURT SITTING IN BEXAR COUNTY, TEXAS FOR
PURPOSES OF ALL LEGAL PROCEEDINGS ARISING OUT OF OR RELATING TO THE LOAN
DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY.

                                       31
<PAGE>
        SECTION 8.10 COUNTERPARTS; EFFECTIVENESS. This Agreement may be signed
in any number of counterparts, and by each of the parties hereto on separate
counterparts, all of which taken together shall constitute one and the same
instrument. This Agreement shall become effective when the Bank shall have
received counterparts hereof signed by all of the parties hereto.

        SECTION 8.11 INDEPENDENCE OF COVENANTS. Each covenant and agreement of
the Borrower under each Loan Document shall be given independent effect so that,
if a particular action or condition is prohibited or required by any covenant,
the fact that it would be permitted by an exception to, or be otherwise within
the limitations of, another covenant shall not avoid the occurrence of a Default
or Event of Default if such action is taken or condition exists.

        SECTION 8.12 SURVIVAL. The Obligations of the Borrower under Sections
8.3, 8.4, 8.8, 8.18 and 8.20 shall survive the termination of this Agreement,
the payment of all other Obligations and the termination of the Commitment. The
representations and warranties set forth in this Agreement and each of the other
Loan Documents shall survive the execution, delivery and performance of this
Agreement and the other Loan Documents and shall continue until one year after
the later of (i) the repayment of the Obligations and (ii) the date on which the
Bank's obligations to make Loans shall have fully and finally terminated; and
any investigation at any time by or on behalf of the Bank shall not diminish any
of their respective rights to rely thereon.

        SECTION 8.13 SEVERABILITY. Incase any one or more of the provisions or
part of a provision contained in any Loan Document shall for any reason be held
to be invalid, illegal or unenforceable in any respect in any jurisdiction, such
invalidity, illegality or unenforceability shall be deemed not to affect any
other jurisdiction or any other provision or part of a provision of any Loan
Document, but such Loan Document shall be reformed and construed in such
jurisdiction as if such provision or part of a provision held to be invalid or
illegal or unenforceable had never been contained herein and such provision or
part reformed so that it would be valid, legal and enforceable in such
jurisdiction to the maximum extent possible.

        SECTION 8.14 GOVERNMENTAL REGULATION. Anything contained in any Loan
Document to the contrary notwithstanding, the Borrower acknowledges and agrees
that the Bank shall not be obligated (i) to extend or fund any credit or other
financial accommodation to, or for the benefit of, the Borrower in an amount, or
(ii) to perform any other agreement or obligation to, or for the benefit of, the
Borrower in any regard, in contradiction or violation of any limitation or
prohibition provided by any applicable statute or regulation, or any
interpretation, ruling, decision, opinion or other pronouncement in respect
thereto (whether or not having the effect of law), which any of them believes is
applicable.

        SECTION 8.15 NO CONTROL. None of the covenants, terms or other
provisions of any Loan Document or any document executed in conjunction
therewith or related thereto shall, or shall be deemed to, give the Bank rights
or powers to exercise control over, or participate in the management of, the
business, affairs, operations or management of the Borrower or any of its
respective Property, including any right or power to influence or affect any of
its treatment, 

                                       32
<PAGE>
transportation, storage or disposal of toxic and/or hazardous waste, substances
or constituents. The relationship between the Borrower and the other parties
hereto created by this Agreement and each of the other Loan Documents is only
that of debtor-creditor (with or without security as applicable), and the Rights
of such other parties hereunder and thereunder are limited to the rights to
receive payment of the Obligations and to exercise the Rights provided herein
and therein and in any other document executed in conjunction herewith or
therewith or related hereto or thereto.

        SECTION 8.16 RENEWALS, EXTENSIONS, REARRANGEMENTS, TERMINATION, ETC.
With respect to each and every (i) renewal, extension, increase and
rearrangement, if any, of the Obligations, or any part thereof, and (ii)
amendment, modification, supplement, restatement, waiver and consent, if any, of
or to this Agreement or any other Loan Document, all provisions of this
Agreement and the other Loan Documents shall apply with equal force and effect
to each such event or circumstance, except to the extent, if any, expressly set
forth in connection with each such event or circumstance; provided, however, the
foregoing is not intended in any regard to convey, acknowledge or otherwise
evidence on the part of the Bank, expressly or by implication, any present
consent or agreement to any such event or circumstance occurring subsequent to
the date hereof, it being acknowledged and agreed that the entry by the parties
hereto to any such events or circumstances shall be evaluated as they occur and
subject to the other provisions of the Loan Documents, as same may be
applicable. Except as expressly provided therein, all Loan Documents shall
remain in effect until full and complete payment of all Obligations, termination
of all commitments and obligations of the Bank to make or extend any credit or
financial accommodation to, or for the benefit of, any Borrower, and receipt by
the Bank, or any of the foregoing Persons, if so requested, of such written
assurances of each Borrower and any other designated Person or Persons that no
other claims, rights, defenses, liabilities or obligations exist in respect
hereto or against any of them or any other Indemnified Party.

        SECTION 8.17 CONFLICTS. In the event of any inconsistency or conflict
between the terms of this Agreement and the terms of any other Loan Document,
the terms of this Agreement shall control.

        SECTION 8.18 CONFIDENTIALITY. The Bank agrees to use reasonable
precautions to keep confidential, in accordance with customary procedures for
handling confidential information of this nature and in accordance with safe and
sound banking practices, any non-public information supplied to it by the
Borrower pursuant to this Agreement which is identified by the Borrower as being
confidential at the time the same is delivered to the Bank, provided that
nothing herein shall limit the disclosure of any such information (i) to the
extent required by statute, rule, regulation or judicial process, (ii) to
counsel for the Bank, (iii) to bank examiners, auditors or accountants of the
Bank, (iv) to any other Bank, (v) in connection with any litigation to which the
Bank is a party, provided, further, that, unless specifically prohibited by
applicable Law or court order, the Bank shall, at least five Business Days prior
to disclosure thereof, notify the Borrower of any request for disclosure of any
such non-public information (A) by any governmental agency or representative
thereof(other than any such request in connection with an examination of the
Bank's financial condition by such governmental agency) or (B) pursuant to legal
process, or (vi) to any Transferee (or prospective 

                                       33
<PAGE>
Transferee) so long as such Transferee (or prospective Transferee) agrees in
writing to handle such information confidentially.

        SECTION 8.19 PROVISIONS CONCERNING LOCK BOX. Borrower does hereby
irrevocably appoint the Bank as each Company's attorney-in-fact and hereby
grants to the Bank an unrestricted and unqualified power of attorney, coupled
with an interest, to endorse or sign the name of each Company (as appropriate)
on all checks or drafts payable to each Company or to their respective orders,
to take possession of all collections, receipts or other documents whatsoever,
and to take possession of and open mail addressed to each Company and remove
therefrom any payment on account (prior to delivering such mail to the
Companies, as appropriate with respect to any and all Accounts Receivable or
other claims owned by each Company at any time, of whatever nature, however or
from whatever source arising. The Companies have or will set up a lock box with
the Bank, by executing at Closing, a separate lock box agreement with the Bank
in a form acceptable to the Bank, and deliver or cause to be delivered, all keys
to such lock box to the Bank. The lock box shall be and remain under the
exclusive control of the Bank. Immediately after the Closing, each of the
Companies will direct each of its Account Debtors to make payments due under or
with respect to any and all of each Company's Accounts Receivable directly to
the lock box. All receipts from the lock box shall be deposited to each
Company's account (as appropriate) in accordance with the separate lock box
agreement so long as there is no Default hereunder. Upon the occurrence of a
Default hereunder, the Bank shall have the right, and the Borrower hereby
authorizes the Bank, to deposit into a special collateral account to be
established and maintained with the Bank, all checks, drafts and cash payments
received in said lock box. All deposits in said collateral account shall
constitute proceeds of Collateral and shall not constitute payment of any
Indebtedness owing to the Bank by the Borrower. At its option, the Bank may, at
any time, apply finally collected funds on deposit in said collateral account to
the payment of the Indebtedness of Borrower to the Bank in such order of
application as the Bank may determine or, at the sole discretion of the Bank,
the Bank may permit any Company (as appropriate) to withdraw all or any part of
the balance on deposit in said collateral account. Upon the occurrence of a
Default hereunder, the Companies will promptly deliver to the Bank, for deposit
into the collateral account, all payments on account and chattel paper received
by any of them representing payments on or evidence of any of their respective
Accounts Receivable. All such payments shall be delivered to the Bank in the
form received(except for a Company's endorsement where necessary). Until so
deposited, all payments on account and any chattel paper received by any of the
Companies shall be held in trust by such Company for and as the property of the
Bank and shall not be commingled with any other funds or Property whatsoever.

        SECTION 8.20 PAYMENTS SET ASIDE. To the extent that the Borrower makes a
payment or payments to the Bank (or its Transferee), or the Bank (or its
Transferee) enforces any Lien or exercises its right of setoff, and such payment
or payments or the proceeds of such enforcement or setoff, or any part thereof,
are subsequently invalidated, declared to be fraudulent or preferential, set
aside and/or required to be repaid to a trustee, receiver or any other Person
under any Debtor Laws or equitable cause, then, to the extent of such recovery,
the obligation or part thereof originally intended to be satisfied, and all
rights and remedies therefor, shall be revived and shall continue in full 

                                       34
<PAGE>
force and effect as if such payment had not been made or such enforcement or
setoff had not occurred.

        SECTION 8.21 LIMITATION OF LIABILITY; COMMENCEMENT OF ACTIONS. To the
extent not prohibited by applicable Law, no claim may be made by or on behalf of
the Borrower or any other Person against the Bank or any other Indemnified Party
for any special, indirect, consequential or punitive damages in respect of any
claim for breach of contract arising out of or related to the transactions
contemplated by any Loan Document, or any act, omission, or event occurring in
connection therewith (whether any of such is a claim based on contract, tort,
duty imposed by law or otherwise), and Borrower hereby waives, releases, and
agrees not to sue, or commence or authorize the commencement of any Litigation,
upon any claim for any such damages, whether or not accrued and whether or not
known or suspected to exist in its favor. Further, any claim made by or on
behalf of the Borrower or any other Person against the Bank or any other
Indemnified Party shall be barred unless it is asserted by the commencement of
an action or proceeding in a court as prescribed in Section 8.9 by the filing of
a complaint therein within one year after the first act, occurrence or omission
upon which such claim or cause of action, or any part thereof, is based,
discovered or, in the exercise of reasonable diligence, should have been
discovered; and the Borrower agrees that such period of time is a reasonable and
sufficient time for it to investigate and act upon any such claim or cause of
action. The provisions of this Section 8.20 shall survive any termination,
howsoever occurring, of this Agreement and each Loan Document and the full and
final payment of the Notes and the other Obligations.

        SECTION 8.22 REVIEW. The Borrower acknowledges and represents to the
Bank that Borrower has reviewed this Agreement and each other Loan Document, has
had the benefit of legal counsel of its own choice throughout its review and
negotiation of this Agreement and each other Loan Document, has been afforded an
opportunity to review and negotiate this Agreement and each other Loan Document
with the advice of its legal counsel, and is fully informed and knowledgeable of
the terms, provisions, rights and effects of this Agreement and each other Loan
Document. In furtherance of the foregoing, but not in limitation thereof, the
Borrower acknowledges and agrees that each Loan Document should be and shall be
construed as if jointly drafted by the parties hereto.

        SECTION 8.23 THIS AGREEMENT. THIS WRITTEN LOAN AGREEMENT AND ALL OTHER
LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT AMONG THE PARTIES WITH RESPECT TO
THE SUBJECT MATTER COVERED HEREBY AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS OR SUBSEQUENT ORAL AGREEMENTS BY THE PARTIES. THERE ARE
NO UNWRITTEN ORAL AGREEMENTS BETWEEN OR AMONG THE PARTIES.

                              CERTAIN DEFINITIONS

As used herein, the following terms shall have the respective meanings assigned

        "ACCEPTABLE ACCOUNT RECEIVABLE" means an Account Receivable as to which
payment is due not more than 90 days from the original date of invoice and as to
which payment in accordance with such terms is not delinquent or past due. If
payment of any Account Receivable is due more than 90 days after the date of
invoice, or with respect to any Accounts Receivable, if payment by the Account

shall no longer be, an "Acceptable Account Receivable" for purposes of this
Agreement.

        "ACCOUNT DEBTOR" means, with respect to any Account Receivable, the
Person obligated to pay such Account Receivable.

        "ACCOUNT RECEIVABLE" means any intangible property or right owned by any
Company at any time consisting, in whole or part, of a legally enforceable right
to receive from any Person, or require the payment by any Person of, a certain
amount of money whenever arising, however or whenever acquired or evidenced,
whether due or to become due, and whether or not earned by performance,
including but not limited to, obligations evidenced by notes, installment
purchase agreements, accounts, and/or contracts, and all contract rights,
chattel paper, instruments and general intangibles, excluding, however, any such
intangible property or rights arising solely from services rendered or materials
provided by a Company outside of the USA to any Person not domiciled in the USA.

        "ACQUISITION" means the following: (i) the purchase or acquisition by
any Person of all of (A) the capital stock of a corporation, (B) the membership
interests of a limited liability company or (C) the partnership interests of a
general or limited partnership, provided that each such transaction results in
such Person possessing the power to control the management and policies of such
corporation or (ii) the acquisition of the assets of a going concern business
(as defined in accordance with GAAP).

        "ACQUISITION TARGET" means the Person which is the subject of an
Acquisition by Borrower.

any Person, means a member of the board of directors, a partner or an officer of
such Person, or any other Person with possession, directly or indirectly, of the
power to direct or cause the direction of the management and policies of such
Person, through the ownership (of record, as trustee or by proxy) of Voting
Shares, through a management contract, or otherwise. Any Person owning or
controlling directly or indirectly 10% or more of the Voting Shares, or other
equity interests of another Person shall be deemed to be an Affiliate of such
Person.

<PAGE>
        "AGREED MAXIMUM RATE" means a per annum rate of interest equal to 5.0%

while there is no Maximum Rate applicable to the transactions contemplated
hereby.

        "AGREEMENT", "HEREOF","HERETO", "HEREIN", "HEREUNDER" and words of
similar import means this Agreement as a whole, and not any particular article

modified or supplemented from time to time.

        "APPLICABLE LAW" means, with respect to the Bank, the law in effect,
from time to time, applicable to this loan transaction and each Loan Document
which lawfully permits the contracting for, taking, reserving, receiving,
charging and/or collection of the maximum lawful, non-usurious rate of interest
by such Person on each Loan Document and the transactions evidenced thereby, and
arising in connection therewith (including, but without limitation, the
Notes),including laws of the State of Texas, to the extent controlling, the laws
of the United States of America, and laws of any jurisdiction whose laws may be
mandatorily applicable to such Person, notwithstanding other provisions of any
Loan Document or laws of the United States of America applicable to such Person
and the transaction contemplated hereby, which would permit such Person to
contract for, take, reserve, receive, charge or collect a greater amount of
interest then under such jurisdiction's law. To the extent that Applicable Law
is determined by reference to Article 1.04, Title 79, Revised Civil Statutes of
Texas, 1925, as amended, the interest ceiling applicable hereto and in
connection herewith shall be the "indicated" (weekly) rate ceiling as defined in
said Article 1.04; provided however, it is agreed that the terms hereof,

extensions, modifications, alterations, refinancings and rearrangements of all
or any part of the Indebtedness.

        4. BENEFITS TO GUARANTOR. Guarantor acknowledges, warrants and
represents to Lender that Guarantor will derive or expects to derive financial

given to induce Lender to extend credit to Borrower which would not be extended

agreement between Guarantor and Lender with respect to Guarantor's guarantee of
the Indebtedness; provided, however, this Guaranty is in addition to and does
not replace, cancel, modify, impair, or affect any other guaranty executed by
Guarantor and now or hereafter held by Lender that relates to Borrower or any
other person or entity. No representations or agreements have been made by
Lender to Guarantor except as contained in this Guaranty. Guarantor has read and
understands the implications of this Guaranty. Guarantor agrees to the terms,
provisions and conditions of the Note, the Loan Documents which may have been or
may hereafter be executed by Borrower or other persons evidencing, securing or
in connection with the Indebtedness or any part thereof, and agrees that
Guarantor's liability shall in no manner be affected, impaired or released by
reason of any term, provision or condition of the Note, the Loan Documents or
loan agreement or by the failure, refusal or omission of Lender to enforce or
observe any of same or by any action taken or omitted to be taken by Lender
pursuant thereto or in connection therewith.

        7. PAYMENT BY GUARANTOR. In each event that all or any portion of the
Indebtedness shall become due and remain unpaid (however the maturity may have
occurred), Guarantor will, upon demand, pay the amount due to Lender (other than
any interest as may be in excess of the Maximum lawful amount), without notice
having been given to Guarantor previous to such demand of the acceptance by
Lender of this Guaranty or of the creating or incurring of such indebtedness.
Guarantor specifically agrees that it shall not be necessary or required in
order to enforce any obligations under this Guaranty that Lender has made demand
for payment upon Borrower or any other person liable on the Indebtedness for
payment thereof or has presented same for payment by Borrower or any other
person liable thereon or has made protest thereof or has given notice to
Borrower or any other party liable thereon of the maturity or nonpayment of the
Indebtedness. All amounts becoming payable by Guarantor to Lender under this
Guaranty shall be payable at Lender's Address stated above, or at such other
address as directed by Lender in written notice to Guarantor. All payments made
upon the Indebtedness at any time shall be deemed to have been paid by Borrower
unless express notice in writing is given to Lender at the time of payment by
Guarantor that Lender has been paid by Guarantor.

        9. COSTS OF COLLECTION. Guarantor agrees to pay all costs of collection,
including attorney's fees and expense, if this Guaranty is placed in the hands
of an attorney for collection or is collected through any court.

        10. WAIVER BY GUARANTOR. Guarantor specifically waives any notice of
acceptance of this Guaranty by Lender and of the creation, advancement,

rearrangement of the Indebtedness, or any indulgence with respect to the

accelerate the maturity of the Indebtedness, notice of acceleration of the
maturity of the Indebtedness, demand, protest, or presentment with respect to
the Indebtedness, and Guarantor waives notice of the amount of the Indebtedness
outstanding at any time. Guarantor agrees that the maturity of the Indebtedness,
or any part thereof, may be accelerated, renewed, extended, modified,
refinanced, rearranged or any other indulgence may be granted with respect
thereto by Lender at its will or as may be agreeably Borrower without notice to
or further consent by Guarantor at any time. Guarantor agrees that Guarantor
shall not be considered a "Debtor" as defined in Section 9.105 of the Texas
Business and Commerce Code or Section 51.002 of the Texas Property Code.

        11. GUARANTOR'S DIRECT LIABILITY. Lender shall not be required, before

or requiring payment of the Indebtedness by Guarantor hereunder, or at any time
thereafter, to do any of the following:

                (a) proceed to obtain or assert a claim for personal judgment
        against Borrower for the Indebtedness or make any effort at collection
        of the Indebtedness from Borrower;

                (b) foreclose against or seek to realize upon the Collateral or
        any security now or hereafter existing for the Indebtedness;

                (c) file suit or proceed to obtain or assert a claim for
        personal judgment against any other party (including any maker,
        guarantor, endorser or surety) liable for the Indebtedness or make any
        effort at collection of the Indebtedness from any such other party;

                (d) exercise or assert any other right or remedy to which Lender
        is or may be entitled in connection with the Indebtedness or any
        security or other guaranty therefor;

                (e) assert or file any claim against the assets or estate of
        Borrower or other person liable for the Indebtedness, or any part
        thereof;

                (f) take any action against Borrower or any other person, to
        exhaust its remedies against endorsers, the Collateral or other
        collateral or security, or to resort to any balance of any deposit
        account or credit on the books of Lender in favor of Borrower or any
        other person; or

                (g) pursue any other remedies Lender may have in connection with
        the Indebtedness.

        12. OBLIGATIONS NOT IMPAIRED. Guarantor's obligations under this
Guaranty shall not be released, diminished, impaired, reduced, or adversely
affected, and Guarantor waives any common 

                                     Page 3
<PAGE>
law, equitable, statutory or other rights that Guarantor might otherwise have,
as a result of any of the following:

                (a) any full or partial release of the liability of Borrower,
        any other guarantor of the Indebtedness, or any other person primarily
        or secondarily liable on the Indebtedness, or any part thereof
        (including any maker, endorser, guarantor or surety), whether such
        liability is direct or indirect, joint, several, or joint and several,
        it being recognized, acknowledged and agreed that Guarantor may be
        required to pay the Indebtedness in full without assistance of any other
        party, and Guarantor has not been induced to enter into this Guaranty on
        the basis of an understanding or agreement that other parties will at
        all times be liable to pay the Indebtedness, or that Lender will look to
        other parties to pay the Indebtedness; provided, however, nothing in
        this Guaranty shall waive or release, either expressly or impliedly, any
        rights of subrogation, reimbursement or contribution that Guarantor may
        have, after payment in full of the Indebtedness, against others liable
        under the Indebtedness, but Guarantor's rights of subrogation,
        reimbursement and contribution are secondary, subordinate and inferior
        to the rights and claims of Lender;

                (b) the voluntary or involuntary liquidation, sale or other
        disposition of all or substantially all of the assets of Borrower, or
        any receivership, insolvency, bankruptcy, reorganization or other
        similar proceedings affecting Borrower or any of its assets;

                (c) any impairment, modification, release or limitation of
        liability of Borrower, or stay of foreclosure or other lien enforcement
        proceedings against Borrower, or Borrower's property, or Borrower's
        estate in bankruptcy, or any modification, discharge or extension of the
        Indebtedness resulting from the operation of any present or future
        provision of the Federal Bankruptcy Code or other bankruptcy laws, or
        from the decision of any court, it being recognized, acknowledged and
        agreed that Guarantor shall remain liable on the Indebtedness,
        notwithstanding any act, omission or thing which might, but for the
        provisions hereof, otherwise operate as a legal or equitable discharge
        of Guarantor;

                (d) any release of, subordination of, or substitution of any
        security or other guaranty now or hereafter held by Lender for payment
        of the Indebtedness, or of any part thereof;

                (e) Lender's failure to use diligence or care in preserving the
        liability of any person on the Indebtedness, or in bringing suit to
        enforce collection of the Indebtedness;

                (f) the addition of another guarantor or guarantors of the
        Indebtedness;

                (g) the substitution or withdrawal of collateral or release of
        security;

                (h) any renewal, extension, modification, alteration,
        refinancing or rearrangement of or any other indulgence with respect to
        the Indebtedness, or any part thereof;

                (i) the exercise, failure to exercise, delay, omission or lack
        of diligence or care by Lender in exercising any right or power
        conferred upon Lender in this Guaranty, the Note, the Security
        Agreement, or any Loan Document evidencing, securing or relating to the
        Note or by law or in equity;

                (j) Borrower's not being liable for the Indebtedness because the
        act of creating the Indebtedness is ultra vires, or the officers or
        persons creating the Indebtedness acted in 

                                     Page 4
<PAGE>
        excess of their authority, or for any reason the Indebtedness cannot be
        enforced against Borrower;

                (k) any payment by Borrower to Lender if such payment is held to
        constitute a preference under the Federal Bankruptcy Code or other
        bankruptcy laws, or if for any other reason Lender is required to refund
        such payment to Borrower or pay the amount thereof to any other party;

               (l) Guarantor's being or becoming liable for any indebtedness
        owing by Borrower to Lender, by endorsement or otherwise, other than
        under this Guaranty; or

               (m) the invalidity, illegality or unenforceability of all or any
        part of the Indebtedness, for any reason whatsoever, including without
        limitation the fact that the Note or other Loan Documents pertaining to
        the Indebtedness have been forged or otherwise are irregular or not
        genuine or authentic.

        13. APPLICATION OF PAYMENTS. If Lender should collect or receive any
payments from any person other than Guarantor, or funds which are not
specifically required by law or agreement to be applied to the Indebtedness,
then Lender may, in Lender's sole discretion, apply such payments to any
indebtedness of Borrower other than the Indebtedness. Guarantor agrees that
Lender may apply payments or other funds received by Lender from Borrower, from
any other party obligated on the Indebtedness, from the liquidation of any
collateral now or hereafter securing the Indebtedness, or from any other source,
including without limitation, insurance proceeds and condemnation, to the
Indebtedness in any manner or order as Lender may deem appropriate in its sole
and absolute discretion.

        14. COLLECTION OF INDEBTEDNESS. Guarantor expressly waives any right to
the benefit of or to require or control application of any security or the
proceeds of any security now existing or hereafter obtained by Lender as
security for the Indebtedness, or any part thereof, and agrees that Lender shall
have no duty to apply to the Indebtedness any monies, payments or other property
at any time received by or paid to or in the possession of Lender, except as
Lender shall determine in its sole discretion. Guarantor specifically agrees
that Guarantor shall not have any recourse or action against Lender by reason of
any action Lender may take or omit to take in connection with the Indebtedness,
the collection of any sums or amounts herein mentioned, or in connection with
any security for or any other guaranty of the Indebtedness.

        15. SUBORDINATION. Guarantor subordinates all indebtedness owing to
Guarantor from Borrower to the Indebtedness. Guarantor further subordinates any
liens or security interest it may have in the collateral or security of Borrower
(or any other party) to the liens and security interests in favor of Lender
securing the Indebtedness. Guarantor agrees not to accept any payments or
satisfaction of any kind of any indebtedness of Borrower to Guarantor. If
Guarantor should receive any such payment or satisfaction for indebtedness of
Borrower to Guarantor in violation of the above terms, Guarantor agrees to
deliver the payment or satisfaction to Lender, and until delivered, Guarantor
agrees to hold the same in trust for Lender.

        16. FINANCIAL INFORMATION. Guarantor warrants and represents to Lender
that all financial statements and cash flow statements delivered by or on behalf
of Guarantor prior to the date hereof are true and correct, that there are no
material adverse changes as of the date of This Guaranty, and that the execution
of this Guaranty does not render Guarantor insolvent.

        17. NOTICE OF LITIGATION, CLAIMS, AND FINANCIAL CHANGE. Guarantor shall
promptly inform Lender of any litigation against Guarantor or affecting any
security for the Indebtedness which, if 

                                     Page 5
<PAGE>
determined adversely, might have a material adverse effect upon the financial
condition of Guarantor or upon such security or might cause a default under any
of the documents evidencing, securing or governing the Indebtedness, any claim
or controversy which might become the subject of litigation, and any material
adverse change in the financial condition of Guarantor.

        18. USURY DISCLAIMER. No provision herein or in any promissory note,
security instrument, or any other loan agreement executed by Borrower or
Guarantor evidencing the Indebtedness shall be construed to be or to create a
contract by Guarantor to pay, as consideration for the use, forbearance, or
detention of money, interest in excess of the rate or amount allowed by Law. If
any excess of interest in such respect is provided for herein or in any such
promissory note, security instrument, or any other loan agreement, the
provisions of this Section shall govern, and neither Borrower nor Guarantor
shall be obligated to pay the amount of such interest to the extent that it is
in excess of the amount permitted by applicable law. The intention of the
parties is to conform strictly to the usury laws now in force, and all
promissory notes and Loan Documents executed by Borrower or Guarantor evidencing
the Indebtedness shall be held subject to reduction to the amount allowed under
said usury laws as now or hereafter construed by the courts having jurisdiction.

        19. TRANSFERABILITY. This Guaranty is intended for and shall inure to
the benefit of Lender and each and every other person who shall from time to
time be or become the owner or holder of any of the Indebtedness, and each and
every reference herein to Lender shall also include and refer to each and every
successor or assignee of Lender at any time holding or owning any part of or
interest in any part of the Indebtedness. This Guaranty shall be transferable
and negotiable, with the same force and effect and to the same extent that the
Indebtedness is transferable, it being understood and stipulated that upon the
assignment or transfer by Lender of any of the Indebtedness the legal holder or
owner of the Indebtedness (or part thereof or interest therein transferred or
assigned by Lender) shall also, unless provided otherwise by Lender in its
transfer or assignment, have and may exercise all of the rights granted to
Lender under this Guaranty to the extent of the part of or interest in the
Indebtedness assigned or transferred to said person. Guarantor expressly waives
notice of transfer or assignment of the Indebtedness, or any part thereof, or of
the rights of Lender hereunder. Notwithstanding anything in this Section to the
contrary, all Indebtedness to Lender shall be paid in full first, before any
assignee or transferee shall receive any benefits of This Guaranty.

        20. INFORMATION CONCERNING GUARANTOR. Guarantor acknowledges and agrees
that Lender may transfer the Indebtedness or partial interests therein to one or
more transferees or participants. Guarantor authorizes Lender to disseminate any
information Lender has pertaining to the Indebtedness, including, without
limitation, credit information on Guarantor, to any such transferee or
participant or prospective transferee or participant.

        21. BINDING ON OTHERS. This Guaranty shall be binding upon Guarantor and
Guarantor's heirs, legal representative, personal representatives, executors,
administrators, successors and assigns.

        22. MODIFICATION OR CONSENT. No modification, consent or waiver of any
provision of this Guaranty shall be effective unless the modification, consent
or waiver is in writing and signed by an officer of Lender, and then shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand on Guarantor in any case shall, of itself, entitle Guarantor
to any other or further notice or demand in similar or other circumstances. No
delay or omission by Lender in exercising any power or right under this Guaranty
shall impair any such right or power or be construed as a waiver thereof or any
acquiescence therein, nor shall any single or partial exercise of any such power
preclude other or further exercise thereof, or the exercise of any other right
or power under this Guaranty. All rights and remedies of Lender under this
Guaranty are cumulative of each other and of every other right or remedy which
Lender may otherwise have at law or in equity 

                                     Page 6
<PAGE>
or under any other contract or document, and the exercise of one or more rights
or remedies shall not prejudice or impair the concurrent or subsequent exercise
of other rights or remedies.

        23. WAIVER OF CERTAIN STATUTORY PROVISIONS. Guarantor hereby waives all
rights to which Guarantor may be or might otherwise become entitled to with
respect to the provisions of Sections 34.02 and 34.03 of the Texas Business and
Commerce Code, as amended, and agrees that the rights of Guarantor pursuant to
the provisions of Section 34.04 of the Texas Business and Commerce Code, as
amended, shall be subject to, secondary, subordinate and inferior in all
respects to the rights of Lender pursuant to this Guaranty.

        24. NOTICES. Any notice or demand to Guarantor may be given and shall
conclusively be deemed and considered to have been given and received upon the
deposit thereof, in writing, in the United States mail, duly stamped and
addressed to Guarantor at Guarantor's Address For Notice stated above, but
actual notice, however given or received, shall always be effective. The last
preceding sentence shall not be construed in any way to affect or impair any
waiver of notice or demand herein provided or to require giving of notice or
demand to or upon Guarantor in any situation or for any reason.

        25. GOVERNING LAW AND PLACE OF PERFORMANCE. GUARANTOR AGREES THAT THIS
GUARANTY IS GOVERNED BY THE LAWS OF THE UNITED STATES AND THE STATE OF TEXAS.
This Guaranty is performable in Bexar County, Texas, and Guarantor hereby waives
the right to be sued elsewhere.

        26. HEADINGS. Section headings of this Guaranty are inserted for
convenience of reference only, and shall not alter, define, or be used in
construing the text of such sections.

        27. PRONOUNS. As used herein and when required by the context, each
number (singular and plural) shall include all numbers, and each gender shall
include all genders, and unless the context otherwise requires the word "person"
or "party" shall include "person, corporation, firm, partnership or
association".

        28. NOTICE OF INVALIDITY OF ORAL AGREEMENTS. THIS WRITTEN AGREEMENT
REPRESENTS THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED
BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE
PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

Frost National Bank
400 Frost Bank Tower

San Antonio, Texas 78205

Ladies and Gentlemen:

        We have acted as counsel to Dawson Production Services, Inc.
("Borrower") and Taylor Companies, Inc. and Dawson Production Acquisition Corp.,
a Delaware corporation, Taylor Companies, Inc., a Texas corporation, Dawson
Production Partners, L.P., f/k/a Pride Land Operations, L.P., a Delaware limited
partnership, Dawson Production Management, Inc., f/k/a Pride Land GP, Inc., a
Delaware corporation, Dawson Production Services de Mexico, S.A. De C.V., a
Mexican corporation and Mobley Vehicle Acquisition Corp., a Texas corporation
(collectively referred to as "Guarantors") in connection with the preparation,
execution and delivery of the Credit Agreement (the "Credit Agreements) dated as
of February __, 1997 between the Borrower and Frost National Bank ("Lender") and
the transactions contemplated by the Credit Agreement. This opinion is being
furnished to you pursuant to the Credit Agreement. Capitalized terms used herein
without definition have the same meanings as in the Credit Agreement.

        This Opinion Letter is governed by, and shall be interpreted in
accordance with, the Legal Opinion Accord (the "Accord") of the ABA Section of
Business Law. As a consequence, it is subject to a number of qualifications,
exceptions, definitions, limitations on coverage and other limitations, all as
more particularly described in the Accord, and this Opinion Letter should be
read in conjunction therewith. The law covered by the opinions expressed herein
is limited to the federal Law of the United States and the Law of the State of
Texas (including, to the limited extent provided herein, the Law of the State of
Texas dealing with the legal issues described in the Accord).

                             1. DOCUMENTS REVIEWED.

        1.1 TRANSACTION DOCUMENTS. As counsel to the Borrower, we have reviewed
copies provided to us of the following documents and instruments dated as of
February __, 1997, unless otherwise stated (collectively, the "Transaction
Documents"):

        (a)     Credit Agreement;

<PAGE>
        (b)     Revolving Note (the "Note") executed by the Borrower and payable
                to the order of Lender;

        (c)     Security Agreements (the "Security Agreements"), executed by the
                Borrower and each of the Guarantors;

        (d)     Guaranty executed by each of the Guarantors; and

        (e)     Financing Statements (Form UCC-1) executed by the Borrower and
                Guarantors to be filed in the office of the Secretary of State
                of Texas, (the "Financing Statement").

              2. QUALIFICATIONS OF FACTUAL AND LEGAL EXAMINATIONS.

        2.1 FACTUAL MATTERS. We have relied as to certain factual matters solely
on the representations and warranties of the Borrower and Guarantors set forth
in the Transaction Documents and the certificates of officers of Borrower and
Guarantors set forth below and have made no other investigation or inquiry other
than to review the following:

        (a)     Articles of Incorporation and Bylaws of Borrower and Guarantors.

        (b)     Certificate of Existence issued by the Secretary of State of
                Texas and Certificates of Good Standing issued by the
                Comptroller of Public Accounts of Texas with respect to Borrower
                and Guarantors.

        (c)     Unanimous Written Consent of Borrower and Guarantors dated
                February ___, 1997, executed by the directors of Borrower and
                Guarantors.

        (d)     Certificate of Incumbency and Resolutions for Borrower and
                Guarantors dated February ___, 1997.

        2.2 GENERAL QUALIFICATIONS. The General Qualifications are applicable to
the opinions expressed in the Opinion Letter. In addition, the enforceability of
certain of the remedial, waiver, subrogation and other provisions of the
Transaction Documents is further subject to all applicable constitutional,
legislative, judicial and administrative provisions, statutes, decisions, ruling
and other laws; however, such laws do not, in our opinion, substantially
interfere with the practical realization of the benefits expressed in the
Transaction Documents (except for the economic consequences of any procedural
delay which may result from such laws).

        2.3 OTHER QUALIFICATIONS. You are hereby notified that (a) we do not
consider you to be our client in the matter to which this opinion relates, (b)
neither the Texas Code of Professional

                                       2
<PAGE>
Responsibility nor current case law clearly articulates the circumstances under
which an attorney may give a legal opinion to a person other than the attorney's
own client, (c) a court might determine that it is improper for us to issue, and
for you to rely upon, a legal opinion issued by us when we have acted as counsel
to the Borrower and Guarantors in connection with the Credit Agreement, and (d)
you may wish to obtain a legal opinion from your own legal counsel as to the
matters addressed in this opinion letter.

                                  3. OPINIONS.

        Based upon and subject to the foregoing and the other qualifications and
limitations stated herein, we are of the opinion that:

        3.1 ORGANIZATION AND AUTHORITY OF THE BORROWER. The Borrower is duly
organized, validly existing and in good standing as a corporation in the State
of Texas and the execution and delivery of the Transaction Documents to which
the Borrower is a party have been duly authorized by all necessary corporate
action.

        3.2 ORGANIZATION AND AUTHORITY OF GUARANTORS. The corporate Guarantors
are duly organized, validly existing and in good standing as corporations under
the laws of the respective jurisdictions of incorporation shown in the Guaranty.
The execution and delivery by corporate Guarantors of the Transaction Documents
to which corporate Guarantors are parties have been duly authorized by all
necessary corporation action. The limited partnership guarantors are duly
organized, validly existing and in good standing as partnerships under the laws
of the respective jurisdictions of formation shown in the Guaranty. The
execution and delivery by the limited partnership Guarantors of the transaction
documents to which the limited partnership Guarantors are parties have been duly
authorized by all necessary partnership action.

        3.3 ENFORCEABILITY OF TRANSACTION DOCUMENTS. The Transaction Documents
to which the Borrower is a party are binding upon and enforceable against the
Borrower. The Transaction Documents to which Guarantors are parties are binding
upon and enforceable against Guarantors.

        3.4 NO VIOLATION OF LAW. The execution and delivery of the Transaction
Documents to which the Borrower and Guarantors are parties, and the performance
of their respective obligations thereunder do not violate applicable provisions
of statutory law or regulation.

        3.5 SECURITY INTERESTS IN PERSONAL PROPERTY. The provisions of the
Security Agreement are effective to create in favor of Lender a valid security
interest in all right, title and interest of the Borrower and Guarantors in that
portion of the Collateral described in each thereof in which a security interest
may be created under Chapter 9 of the Texas Business and Commerce Code (the
"Code"). Upon the filing of the appropriate Financing Statement in the office
of the Secretary of State of Texas, the Security Agreement will constitute a
fully perfected lien on, and security 

                                       3
<PAGE>
interest in, all rights, title and interest of the Borrower and Guarantors, as
the case may be, in all of the Collateral described in each thereof in which
Borrower and Guarantors have an interest and in which a security interest may be
perfected by filing financial statements under Chapter 9 of the Code with the
Secretary of State of Texas.

        3.6 USURY. The Loan, as reflected in the Transaction Documents, is not
usurious under applicable law.

                    4. ASSUMPTIONS CONCERNING PERFECTION OF
                       SECURITY INTERESTS UNDER THE CODE

        With respect to the Opinions stated in paragraphs 3.3 and 3.5 above, the
following assumptions are applicable:

        4.1 ASSUMPTIONS REGARDING FINANCING STATEMENT. For purposes of this
opinion, we have assumed (i) the accuracy of the name of the record owner of any
property and the description thereof, and (ii) the proper filing of the
Financing Statement in the offices in which it is to be filed.

        4.2 ASSUMPTIONS CONCERNING COLLATERAL. We have also assumed that (i) the
Borrower and Guarantors, as the case may be, have good and sufficient title to
the collateral, (ii) the Borrower and Guarantors, as the case may be, have
"rights in the collateral" as that term is used in Section 9.203 of the Code,
(iii) value has been given within the meaning of Section 9.203 of the Code, and
(iv) the chief executive office of the Borrower and Guarantors is located at 901
N.E. Loop 410, Suite 700, San Antonio, Texas 78209-1306.

             5. QUALIFICATIONS TO OPINIONS REGARDING PERFECTION OF
                 SECURITY INTERESTS UNDER CHAPTER 9 OF THE CODE

        With respect to the opinions stated in paragraphs 3.3 and 3.5 above, the
Opinions concerning the security interests of Lender in the collateral are
qualified as follows:

        5.1 EXCLUSIONS. We express no opinion regarding the accuracy or
completeness of any property descriptions contained in the Transaction Documents
or the title to any assets pledged to Lender by Borrower and Guarantors.

        5.2 OTHER QUALIFICATIONS.

        (a) The continuation of any security interest and perfection of any
security interest in collateral consisting of proceeds is limited to the extent
set forth in Section 9.306 of the Code; 

                                       4
<PAGE>
        (b) Continuation statements complying with the Code must be filed with
the filing offices in which each financing statement was filed not more than six
months prior to the expiration of a five year period dating from the date of
filing of the financing statement (or otherwise within the time permitted by
Section 9.403 and the Code) and subsequent continuation statements must be filed
within six months prior to the end of each subsequent five year period and
amendments or supplements to the financing statements and or additional
financing statements may be required to be filed in the event of a change of
name, identity or organizational structure of the debtor or if the debtor
changes the jurisdiction of its place of business (or, if it has more than one
place of business its chief executive office) or the jurisdiction in which
collateral is located;

        (c) In the case of property which becomes collateral after the date
hereof, Section 552 of the Federal Bankruptcy Code limits the extent to which
property acquired by a debtor after the commencement of a case under the Federal
Bankruptcy Code may be subject to a security interest arising from the security
agreement entered into by the debtor before the commencement of the case;

        (d) We express no opinion as to the priority of any security interest.

        (e) The enforceability of the Transaction Documents may be subject to
(i) bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or
similar laws effecting the enforcement of creditors' rights generally; (ii)
general principles of equity (regardless of whether such enforceability is
considered in a proceeding at law or in equity); (iii) matters of public policy;
(iv) the rights of the United States under the Federal Tax Lien Act of 1966, as
amended; and (v) other applicable laws and procedures which may affect the
remedies provided therein, but which do not, in our judgment, make such remedies
as a whole inadequate for the practical realization of the rights and benefits
provided thereby, although they may result in delays thereof (and we express no
opinion as to the economic consequences, if any, of any such delays).

        (f) Provisions of the Transaction Documents which permit the Bank to
take action or make determinations may be subject to a requirement that such
action be taken or such determinations be made on a reasonable basis and in good
faith.

        (g) Further, the opinions expressed herein are based on statutory law
and judicial decisions that are controlling on the date of this letter, and we
do not assume any responsibility to advise you of any future changes in our
opinions which may result from statutory enactments, court or administrative
decisions, or other governmental promulgations occurring after the date of this
opinion letter.

        5.3 LENDER'S ACTIONS. We express no opinion as to the perfection of the
security interest in any Collateral to the extent Lender consented to any
security interest in favor of any

                                       5
<PAGE>
other party or has authorized the disposition of any Collateral or released or
subordinated Lender's security interest therein.

        5.4 LIMITED TO TRANSACTION DOCUMENTS. Our Opinions concerning the
creation and perfection of the security interest in the Collateral are in all
cases limited to the obligations under the Transaction Documents and such future
advances as are made thereunder in accordance with the terms of the Transaction
Documents; no Opinion is expressed as to the effectiveness of the Transaction
Documents to grant and create a security interest with respect to any
indebtedness other than that created by borrowings under the Transaction
Documents.

        5.5 AFTER ACQUIRED PROPERTY. Our opinion with respect to the perfection
of any security interest in documents, instruments and goods in which the
Borrower and Guarantors acquire rights after the date hereof is limited to
property (a) which is located in Texas when the Borrower and Guarantors acquire
rights therein or (b) in which Lender has a purchase money security interest and
(i) which Lender, Borrower and Guarantors understand, at the time the Borrower
and Guarantors acquire rights therein, will be kept in Texas and (ii) which
arrives in Texas within thirty days after the Lender receives possession
thereof.

      6. QUALIFICATIONS AND ASSUMPTIONS REGARDING OPINION REGARDING USURY.

        The Opinions stated in paragraphs 3.3 and 3.6 above are qualified as
follows:

        6.1 Transaction Documents. Our opinions in paragraphs 3.3 and 3.6 above
deal only with the issue of whether Lender has contracted for usurious interest
as reflected by the Transaction Documents. We express no opinion as to whether
Lender may charge or receive usurious interest after the date of execution of
the Transaction Documents. Lender must observe any limitations contained in the
Transactions Documents on the amount of interest which it can charge or receive.

        6.2 COMMITMENT FEE/LOAN FEE. A court could determine that the
compensation designated as a "commitment fee" or as a "loan fee" in the Credit
Agreement should instead be characterized as interest on the Loan or should be
construed as reducing the amount of principal available to the Borrower under
the Loan and we have assumed that such characterization or construction would
not cause the Loan to be usurious.

        6.3 OTHER CHARGES. In HARDWICK V. AUSTIN GALLERY OF ORIENTAL RUGS. INC.,
779 S.W.2d 438 (Text App. -- Austin 1989, writ ref'd), the court held that a
charge of interest in excess of the interest which the maker of the note agreed
to pay was usurious even though the total interest charged on the note was below
the statutory limit. The court based its holding on the conclusion that any
amount of interest charged over the interest provided for in the note was
automatically usurious under Texas law. While the holding in HARDWICK appears to
be contrary to prior law and

                                       6
<PAGE>
also appears to render the spreading doctrine and statute ineffective with
respect to unilateral charges, the Supreme Court of Texas refused to hear an
appeal of the (lower) appellate court's decision. Accordingly, present case law
provides no clear guidance for predicting the enforceability of such spreading
doctrine and statute and, thus, we are expressing no opinion herein as to (a)
the effect of the HARDWICK decision on the Transaction Documents, (b) whether
the spreading provisions of the Transactions Documents are enforceable in the
context of the facts addressed in HARDWICK, and (c) whether a fact scenario
under the Loan similar to that presented in HARDWICK would render the Loan
usurious.

        This Opinion Letter may be relied upon by you only in connection with
the Transaction and may not be used or relied upon by you or any other person
for any purpose whatsoever, except to the extent authorized in the Accord,
without in each instance our prior written consent.

                                   Very truly yours,

                                   JENKENS & GILCHRIST,
                                   A Professional Corporation

payments received by it or as otherwise specifically provided herein, the
transfer and assignment of the Pro Rata Share hereunder shall be without
recourse against, or representation or warranty by, Transferor/Agent.

                                       II.

                                  CONSIDERATION

        In consideration for the transfer and assignment of its Pro Rata Share,
Transferee agrees to pay to Transferor/Agent in immediately available funds, on

                                PARTIAL PAYMENTS

        If the Borrower makes only a partial principal, interest or fee payment
to Transferor/Agent under the Loan Documents, Transferee shall be entitled to
receive an amount equal to the product of (a) the amount Transferee would have
been entitled to receive from Transferor/Agent if the Borrower had made a full
principal, interest or fee payment under the Loan Documents, times (b) a
fraction (i) the numerator of which is the amount of the partial principal,
interest or fee payment made by the Borrower to Transferor/Agent under the Loan
Documents, and (ii) the denominator of which is the amount of the full
principal, interest or fee payment that the Borrower was obligated to pay Bank
under the Loan Documents.

                                       IV.

                             PAYMENTS TO TRANSFEREE

Documents or, if no such time is specified, prior to 12:00 Noon, San Antonio
time, on such day, or (b) on the Business Day next following the day on which
Transferor/Agent receives such payment in good funds, if such payment is
received later than such time. As used herein, the term "Business Day" shall
mean any day which is not a Saturday, Sunday or a legal holiday on which banking
institutions in the State of Texas are authorized by law to close.

                                LETTERS OF CREDIT

        Upon the date of issuance by Transferor/Agent of a Letter of Credit
under the terms of the Credit Agreement, Transferor/Agent shall be deemed,
without further action by any party hereto, to have transferred and assigned to
Transferee, and Transferee shall be deemed, without further action by any party
hereto, to have assumed, its Pro Rata Share of the rights and obligations of
Transferor/Agent in and to such Letter of Credit. Upon Transferor/Agent's
receipt of a Letter of Credit Information Form, Transferor/Agent shall promptly
notify Transferee of the contents thereof. The issuance by Transferor/Agent of
each Letter of Credit shall be subject to the condition precedent that such
Letter of Credit shall be in such form, contain such terms and support such
transactions as shall be reasonably satisfactory to Transferor/Agent and
Transferee. Transferor/Agent shall promptly notify Transferee in the event any
Letter of Credit is presented for payment. On the date of such notice (or if
such notice is given after 12:00 Noon, San Antonio time, on such date, on the
next succeeding Business Day), Transferee shall, without regard to the existence
of a Default or an Event of Default, pay to Transferor/Agent an amount equal to
Transferee's Pro Rata Share of such amount as Transferor/Agent is required to
fund under the terms of the Letter of Credit, together with interest on such Pro
Rata Share for each day from the date the Transferor/Agent pays such draw to the
date of payment by Transferee at a rate of interest per annum equal to the
Federal Funds Rate, as defined in Paragraph VII below.

                                       VI.

                          ADDITIONAL COLLATERAL; SETOFF

        Transferee shall have no interest in any property taken as collateral
security for any other loan or loans made to Borrower by Transferor/Agent, or in
any property now or hereafter in Transferor/Agent's possession or control that
may be or become collateral security for any such loan by reason of the general
description contained in any general loan or collateral agreement held by
Transferor/Agent or by reason of any right of setoff, counterclaim, banker's
lien or otherwise. In the event the Loans are cross-collateralized with any
other loan or loans made to Borrower by Transferor/Agent, proceeds from the
liquidation of Collateral shall be applied first to fully repay the Loans prior
to application to repayment of any such other loan or loans to Borrower from
Transferor/Agent.

                          PAYMENTS ON ACCOUNT; RETURNS

        Transferor/Agent may, but shall not be obligated to, transfer funds to
Transferee which may be due from the Borrower on the date so due prior to
receipt from the Borrower. If any portion of funds are not then received from
the Borrower, Transferee shall, on demand by Transferor/Agent, repay its Pro
Rata Share of the amount not received to Transferor/Agent at the Federal Funds
Rate. "Federal Funds Rate" means the weighted average of the rates on overnight
federal funds transactions with members of the Federal Reserve System in effect
at the Federal Reserve Bank in San Antonio, Texas, as determined on any basis
reasonably selected by the Transferor/Agent. The Federal Funds Rate applicable
each day shall be the Federal Funds Rate reported as applicable to federal funds
transactions on that date. In the case of a Saturday, Sunday or legal holiday,
the Federal Funds Rate shall be the rate applicable to federal funds
transactions on the immediately preceding day for which the Federal Funds Rate
is determined.

                                      VIII.

                           REPAYMENTS TO THE BORROWER

        Transferee shall repay to Transferor/Agent any sums paid to
Transferor/Agent by the Borrower and distributed by Transferor/Agent to
Transferee which Transferor/Agent shall be required to return to the Borrower or
to any receiver, trustee or custodian for the Borrower. In the event Transferee
fails or refuses to make any such payment or fails or refuses to pay its Pro
Rata Share of the Loans to Transferor/Agent directly or through offset by
Transferor/Agent against funds of Transferee on deposit in Transferee's account
or accounts at Transferor/Agent (against which Transferor/Agent is hereby
specifically authorized to offset for such purposes), then, in addition to any
of its rights at law or in equity, Transferor/Agent shall be entitled to fund
Transferee's Pro Rata Share of such payment and offset against Transferee's Pro
Rata Share all sums received by Transferor/Agent hereunder until reimbursed
therefor by Transferee. Furthermore, any such amount paid by Transferor/Agent on
behalf of Transferee shall be payable to Transferor/Agent on written demand
therefor, and shall bear interest for each day from the date of such payment
until it is repaid by Transferee at the Federal Funds Rate.

                                FEES AND EXPENSES

        Transferee shall pay its Pro Rata Share of all reasonable attorneys'
fees and other expenses incurred by Transferor/Agent in connection with the
enforcement of the Obligations of Borrower under any of the Loan Documents.
Transferee shall be entitled to its Pro Rata Share of any payments subsequently
received by Transferor/Agent with respect to fees and expenses paid by
Transferee.

                                       X.

                BORROWER INFORMATION; INDEPENDENT CREDIT ANALYSIS

        To the extent not already provided or made available to Transferee, and
as often as is reasonably requested by Transferee, Transferor/Agent shall
provide Transferee with(a) copies of all Loan Documents; (b) such information as
is then in Transferor/Agent's possession with respect to the current status of
principal and interest payments and interest accruals with respect to the Loans;
(c) copies of all current financial statements from the Borrower and all
guarantors then in Transferor/Agent's possession; and (d) other current factual
information and data in or coming into the possession of Transferor/Agent and
either submitted under the terms of the Loan Documents or otherwise bearing on
the continuing creditworthiness of the Borrower; provided, that nothing
contained in this Paragraph shall impose any liability upon Transferor/Agent for
its failure to provide Transferee any of such Loan Documents, information,
financial statements or other data unless such failure constitutes willful
misconduct or gross negligence on the part of Transferor/Agent; and provided
further, that Transferor/Agent shall not be obligated to provide Transferee with
any information in violation of the law or any contractual restrictions on the
disclosure thereof. Transferee has specifically consented and agreed to the
provisions of Section 8.7(d) of the Credit Agreement. Transferee hereby
acknowledges, agrees and represents: (i) that Transferee has conducted or shall
conduct an independent credit analysis of the Borrower and an investigation or
assessment of risk with respect to the Loans to satisfy itself that its Pro Rata
Share of the Loans is a credit which Transferee would make acting alone,
(ii)that Transferor/Agent has not provided to Transferee, and Transferee has not
relied on or used in any other way, any credit analysis of the Borrower prepared
by Transferor/Agent or an investigation or assessment of risk with respect to
the Commitment prepared by Transferor/Agent, and (iii) Transferee has
independently and without reliance upon Transferor/Agent, and based upon such
documents and information as Transferee deemed appropriate, made its own
decision to enter into this Agreement. Transferor/Agent represents 

                                       6
<PAGE>
and warrants that it has no current actual knowledge that any information,
reports, representations or warranties provided by or on behalf of Borrower in
connection with the Loans are incorrect in any material respect.

                                       XI.

                        LEGAL RELATIONSHIP OF THE PARTIES

        A. APPOINTMENT OF AGENT. Transferor/Agent is hereby appointed agent for
the parties to act as herein specified, and acting in the manner into the extent
provided in this Article XI, Transferor/Agent accepts such appointment.
Transferor/Agent is hereby irrevocably authorized to receive payments of
principal, interest and other amounts due under the Loan Documents and otherwise
to take such action on behalf of the parties, to exercise such powers and to
perform such duties under the Loan Documents as are specifically delegated to,
or required of the Bank by the terms of the Loan Documents, together with all
other powers reasonably incidental thereto, which authorization permits the
Transferor/Agent to perform any of its duties under the Loan Documents by or
through its agents, attorneys or employees. The Transferor/Agent shall have no
duties or responsibilities except those expressly set forth with respect to it
in this Agreement and the Loan Documents. The relationship of the
Transferor/Agent to the Transferee is only that of one entity acting solely as
an administrative agent for another, and nothing in this Agreement or the Loan
Documents, express or implied, is intended to, or shall be construed to,
constitute the Transferor/Agent a trustee or other fiduciary for the Transferee,
or any holder of any of the Notes, nor to impose on the Transferor/Agent duties
and obligations other than those expressly provided for in this Agreement and
the Loan Documents. As to any matters not expressly provided for in this
Agreement or the Loan Documents and any matters to which either this Agreement
or the Loan Documents place within the discretion of the Transferor/Agent, the
Transferor/Agent shall not be required to exercise any discretion or take any
action (and it may request instructions from the parties with respect to any
such matter), in which case it shall be required to act or refrain from acting
(and shall be fully protected and free from liability to the parties in so
acting or refraining from acting)upon the instructions of the parties (including
itself), and such instructions shall be binding upon all parties; provided,
however, (I) the Transferor/Agent shall in all cases be fully justified in
failing or refusing to act under this Agreement or any Loan Documents unless it
shall be indemnified to its satisfaction by the parties against any and all
liability and expense(other than any such liability or expense proximately
caused by the Transferor/Agent's gross negligence or willful misconduct as
determined by a final judgment) which may be incurred by reason of taking or
continuing to take any such action, and (ii) the Transferor/Agent shall not in
any event be required to take any action which (A) is contrary to this
Agreement, any 

                                       7
<PAGE>
Loan Document or Laws, or (B) exposes it to a risk of personal liability that it
considers unreasonable.

        B. DECISIONMAKING. Approval by both Transferor/Agent and Transferee
shall be required with respect to all discretionary decisions of a material
nature that must be made by the Bank under the terms of the Loan Documents.
Immaterial discretionary decisions shall be made by Transferor/Agent acting in
its discretion and in the best interests of the parties. As used in this
subsection, the phrase "discretionary decisions of a material nature" includes
any action, decision, agreement or commitment to the Borrower as to the Loans,
the Credit Agreement or any other Loan Documents which would:

        (1)     Modify the interest rate, payment, or maturity terms of the
                Loans;

        (2)     Renew, modify or extend the Loans;

        (3)     Waive, amend or modify any provision, condition, or requirement
                of the Notes, the Credit Agreement or any other Loan Documents;

        (4)     Release or substitute any Collateral or security for the Loans
                whether or not evidenced by any Loan Documents securing
                repayment of the Loans;

        (5)     Waive any condition, requirement, obligations, or restriction of
                the Borrower under the Notes, the Credit Agreement or the other
                Loan Documents;

        (6)     Release, compromise, discharge, settle or agree to satisfaction
                of the Loans in whole or in part;

        (7)     Release, limit, discharge, settle or agree to satisfaction of
                the liability of the Borrower or of any guarantor;

        (8)     Declare an Event of Default or take any action to enforce the
                Bank's rights against the Borrower, any guarantor, or any
                Collateral under the Notes, the Credit Agreement or any other
                Loan Documents.

In the event Transferor/Agent and Transferee cannot agree to a discretionary
decision of a material nature, Transferor/Agent shall have the right, but not
the obligation, to purchase Transferee's Pro Rata Share for a purchase price
equal to Transferee's Pro Rata Share of outstanding Loans and all unpaid
interest thereon in accordance with the provisions hereof. Alternatively, any
impasse or inability to agree as to a discretionary decision of a material
nature shall be settled by mediation or by mandatory binding arbitration using
the expedited 

                                       8
<PAGE>
Commercial Arbitration Rules of the American Arbitration Association, or any
other arbitration procedure or rules to which the parties agree.

        C. EXCULPATION; AGENT'S RELIANCE. AS AMONG THE PARTIES, NEITHER THE
TRANSFEROR/AGENT NOR ANY OF ITS AFFILIATES, NOR ANY OF ITS OR THEIR DIRECTORS,
OFFICERS, AGENTS, ATTORNEYS, INSURERS, OR EMPLOYEES, NOR ANY OF THEIR
SUCCESSORS, HEIRS, LEGAL REPRESENTATIVES OR ASSIGNS (COLLECTIVELY, THE "AGENT
INDEMNITEES"), SHALL EVER BE LIABLE FOR ANY ACTION TAKEN OR OMITTED TO BE TAKEN
BY ANY OF THEM UNDER OR IN CONNECTION WITH ANY LOAN DOCUMENT, INCLUDING THEIR
OWN NEGLIGENCE OF ANY KIND, EXCEPT THAT EACH SHALL BE RESPECTIVELY LIABLE FOR
ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT, AS DETERMINED BY A FINAL
JUDGMENT. Without limiting the generality of the foregoing or any other
provision of any Loan Document, the Transferor/Agent: (I) may treat the payee of
any Note as the holder thereof until the Transferor/Agent receives and accepts
an assignment and acceptance reasonably satisfactory to the Transferor/Agent;
(ii) may consult with legal counsel (including counsel for any Company),
independent public accountants and other experts and advisors selected by it and
shall be fully protected and free from liability to all parties for any action
taken or omitted to be taken in good faith by it in accordance with the advise
of such counsel, accountants, experts or advisors; (iii)makes no warranty or
representation to any party and shall not be responsible to any party for any
statements, recitals, information, warranties or representations made in or in
connection with any Loan Document, or in any communication or writing made or
delivered in connection therewith; (iv) shall not have any duty to ascertain, to
inquire or to keep itself informed as to the financial condition of the
Companies or any of them or the performance or observance of the terms,
covenants or conditions of any Loan Documents on the part of any Person or to
inspect the Collateral (including the books and records); (v) shall not be
responsible to the parties for the financial condition of the Companies or any
of them or the due execution, legality, validity, enforceability,
collectibility, genuineness, sufficiency or value of any Loan Document or
instrument or other document furnished in connection therewith or the creation,
perfection, continued creation or perfection, or priority, of any security
interest purported to be created by any Loan Document, or any other instrument
or document furnished pursuant hereto or thereto; and (vi) may rely, and shall
be fully protected and free from liability to all parties in relying (A) upon
the representations and warranties of any Company and the parties in exercising
its powers thereunder, and (B) upon any notice, consent, certificate, statement,
resolution, instrument or other writing (which may be by telegram, cable,
telecopy, facsimile, telex, mail, or telephone) believed by it to be genuine and
signed, sent, communicated or otherwise made by the proper Person.

        D. DEFAULTS. The Transferor/Agent shall not be deemed to have knowledge
of the occurrence of a Default or Event of Default (other than the non-payment
of principal of or 

                                       9
<PAGE>
interest on Loans or of fees in connection therewith) unless the
Transferor/Agent has received written notice from any party specifying the
occurrence of such Default or event of Default and stating that such notice is a
"Notice of Default". In the event that the Transferor/Agent receives a Notice of
Default, it shall give prompt notice thereof to the parties (and shall give each
party prompt notice of any non-payment). The Transferor/Agent shall take such
action with respect to such Default or Event of Default as shall be directed
jointly by parties after due consultation; provided that, unless and until the
Transferor/Agent shall have received such directions, the Transferor/Agent may
(but shall not be obligated to) take such action, or refrain from taking such
action, with respect to such Default or event of Default as it shall in its sole
and absolute discretion deemed advisable and in the best interest of the
parties. Each party hereto agrees to use its best efforts to immediately inform
the other party of any Default or Event of Default of which it becomes aware.

        E. RIGHTS AS A BANK. Subject to the terms and provisions of this
Agreement, The Frost National Bank (and any successor acting as
Transferor/Agent) in its capacity as a party hereto shall have the same rights
and powers hereunder as any other party and may exercise same as though it were
not the Transferor/Agent, and the terms "party,""parties," "holders of Notes,"
or similar terms shall, unless otherwise expressly indicated, include The Frost
National Bank (and any successor acting as Transferor/Agent) in its individual
capacity. The Frost National Bank (and any successor acting as the
Transferor/Agent) and its Affiliates may accept deposits from, lend money to,
act as trustees under indentures or as transfer agent in respect to capital
stock and generally engage in any kind of banking, trust, investment, financial
advisory or other business with the Borrower and its respective Affiliates, and
may accept fees and other consideration from Borrower and its respective
Affiliates for services in connection with any of the foregoing or otherwise,
all as though it were not the Transferor/Agent hereunder and without having to
account for the same to the parties hereto.

        F. INDEMNIFICATION. EACH PARTY AGREES TO INDEMNIFY, REIMBURSE, AND HOLD
HARMLESS EACH AGENT INDEMNITEE (TO THE EXTENT NOT INDEMNIFIED AND REIMBURSED, ON
DEMAND, BY BORROWER), RATABLY ACCORDING TO ITS PRO RATA SHARE, FROM AND AGAINST
ALL LOSSES, LIABILITIES, OBLIGATIONS, CLAIMS, LOSSES, DAMAGES, PENALTIES,
ACTIONS, SUITS, JUDGMENTS, DEMANDS, SETTLEMENTS, COSTS, DISBURSEMENTS OR
EXPENSES (INCLUDING FEES AND EXPENSES OF ATTORNEYS, ACCOUNTANTS, EXPERTS AND
ADVISORS) OF ANY KIND OR NATURE WHATSOEVER (IN THIS PARAGRAPH THE FOREGOING IS
COLLECTIVELY REFERRED TO AS THE "LIABILITIES AND COSTS"), WHICH TO ANY EXTENT
(IN WHOLE OR PART) MAY BE IMPOSED ON, INCURRED BY, OR ASSERTED AGAINST, SUCH
AGENT INDEMNITEE IN ANY WAY RELATING TO, OR RISING OUT OF, THE LOAN DOCUMENTS
AND THE TRANSACTION AND EVENTS (INCLUDING THE ENFORCEMENT THEREOF) AT ANY TIME
ASSOCIATED THEREWITH OR

                                       10
<PAGE>
CONTEMPLATED THEREIN (INCLUDING ANY VIOLATION OR NON-COMPLIANCE WITH ANY
ENVIRONMENTAL LAWS BY ANY PERSON OR ANY LIABILITIES OR DUTIES OF ANY PERSON WITH
RESPECT TO HAZARDOUS MATERIALS FOUND IN OR RELEASED INTO THE ENVIRONMENT) OR AS
A RESULT OF ANY ACTION TAKEN OR OMITTED TO BE TAKEN BY SUCH AGENT INDEMNITEE,
INCLUDING ITS NEGLIGENCE OF ANY KIND, OTHER, THAN AS PROVIDED IN THE FOLLOWING
PROVISO, THE GROSS NEGLIGENCE OF AN AGENT INDEMNITEE; PROVIDED THAT NO PARTY
SHALL BE LIABLE FOR ANY PORTION, IF ANY, OF ANY LIABILITIES AND COSTS WHICH ARE
PROXIMATELY CAUSED BY THE AGENT INDEMNITEE'S OWN INDIVIDUAL GROSS NEGLIGENCE OR
WILLFUL MISCONDUCT, AS DETERMINED IN A FINAL JUDGMENT. WITHOUT LIMITING THE
GENERALITY OF THE FOREGOING, EACH PARTY AGREES, IN PROPORTION TO ITS PRO RATA
SHARE, TO REIMBURSE THE AGENT INDEMNITEE PROMPTLY UPON ITS DEMAND FOR ANY COSTS
AND EXPENSES (INCLUDING ATTORNEYS' FEES AND EXPENSES AND OTHER CHARGES) INCURRED
BY THE AGENT INDEMNITEE IN CONNECTION WITH THE PREPARATION, EXECUTION, DELIVERY,
ADMINISTRATION, MODIFICATION, AMENDMENT OR ENFORCEMENT (WHETHER THROUGH
NEGOTIATIONS, LEGAL PROCEEDINGS OR OTHERWISE) OF, OR LEGAL ADVISE IN RESPECT OF
THEIR RIGHTS OR RESPONSIBILITIES UNDER, THE LOAN DOCUMENTS, OR ANY OF THEM, OR
ANY OTHER DOCUMENTS CONTEMPLATED BY THE LOAN DOCUMENTS, TO THE EXTENT THAT THE
AGENT INDEMNITEE IS NOT REIMBURSED ON DEMAND, FOR SUCH AMOUNTS BY BORROWER. Each
party's obligations under this paragraph shall survive the termination of this
Agreement.

        G. CHANGE OF CONTROL OF TRANSFEREE. If at any time prior to maturity of
the Loans, there is a Change of Control with respect to Transferee,
Transferor/Agent shall have the right, but not the obligation, to purchase
Transferee's Pro Rata Share for a purchase price equal to Transferee's Pro Rata
Share of outstanding Loans and all unpaid interest thereon in accordance with
the provisions hereon.

                                      XII.

                       PERFORMANCE THROUGH REPRESENTATIVES

        Transferor/Agent may perform any of its duties hereunder by or through
officers, directors, employees, attorneys or agents (collectively,
"Representatives"), and Transferor/Agent and its Representatives shall be
entitled to rely, and shall be fully protected in relying, upon any
communication or document believed by them to be genuine and correct

other funds or property, but will hold them separate and upon an express trust
for Secured Party. Secured Party may from time to time apply the whole or any
part of the funds in the special account against the Indebtedness. Unless
Secured Party notifies Debtor in writing that it dispenses with any one or more

delay in delivery or performance, or claim made, in regard to any Collateral;

            (b) keep returned goods segregated from Debtor's other property, and

(i) if the account is not paid when due; (ii) if purchaser rejects the goods or
services covered by the account; or (iii) if Secured Party shall at any time
reject the account as unsatisfactory. Secured Party may retain the account in
Collateral. Secured Party may charge any deposit amount of Debtor with any such
amounts.

books and records covering the Collateral. Debtor immediately will mark all
books and records with an entry showing the absolute assignment of all accounts
in Collateral to Secured Party and Secured Party is hereby given the right to
audit the books and records of Debtor relating to Collateral at any time and
from time to time. The amounts shown as owed to Debtor on Debtor's books and on
any assignment schedule will be the undisputed amounts owing and unpaid. Debtor
shall disclose to Secured Party all agreements modifying any account,
instrument, or chattel pater.

      4.13 DISPOSITION OF COLLATERAL. If disposition of any Collateral gives
rise to an account, chattel paper, or instrument, Debtor immediately shall
notify Secured Party, and upon request of Secured Party shall assign or endorse
the same to Secured Party. No Collateral may be sold, leased, manufactured,
processed, or otherwise disposed of by Debtor in any manner without the prior
written consent of Secured Party.

      4.14 ACCOUNTS RECEIVABLE. Each account receivable constituting Collateral
will represent the valid and legally enforceable obligation of third parties and
shall not be evidenced by any instrument or chattel paper. In the event any
account shall give rise to any instrument or chattel paper, Debtor shall
immediately endorse the same to Secured Party and deliver all original such
instruments and chattel paper to Secured Party.

      4.15 LOCATION OF ACCOUNTS. Debtor shall give Secured Party written notice
of each office of Debtor in which records of Debtor pertaining to accounts in
Collateral are kept, and of any change of any such

SECURITY AGREEMENT                 Page 4
<PAGE>
location. If no such notice is given, all records of Debtor pertaining to
accounts are and shall be kept at Debtor's address shown above.

      4.16 NOTICE OF CHANGES. Debtor will notify Secured Party immediately of
any material change in the Collateral, of a change in Debtor's residence or
location, of a change in any matter warranted or represented by Debtor in this
Agreement or furnished to Secured Party, and of any Event of Default.

      4.17 USE AND REMOVAL OF COLLATERAL. Debtor will not use the Collateral
illegally nor permit the Collateral to be affixed to real or personal property
without the prior written consent of Secured Party. Debtor will not permit any
of the Collateral to be removed from the locations specified herein without the
written consent of Secured Party.

      4.18 POSSESSION OF COLLATERAL. If the Collateral is chattel paper,
documents, instruments, or investment securities or other instruments, Secured
Party may deliver a copy of this Agreement to the broker or seller thereof, or
any person in possession thereof, and such delivery shall constitute notice to
such person of Secured Party's security interest therein and shall constitute
Debtor's instruction to such person to deliver to Secured Party certificates or
other evidence of the same as soon as available. Debtor will deliver all
investment securities, other instruments, documents, and chattel paper which are
part of the Collateral and in Debtor's possession to the Secured Party
immediately, or if hereafter acquired, immediately following acquisition,
appropriately endorsed to Secured Party's order, or with appropriate, executed
powers. Debtor waives presentment, demand, notice of dishonor, protest, and all
other notices with respect thereto.

      4.19 CHATTEL PAPER. Debtor has perfected or will perfect a security
interest by means satisfactory to Secured Party in goods covered by chattel
paper in Collateral.

      4.20 CONSUMER CREDIT. If any Collateral or proceeds includes obligations
of third parties to Debtor, the transactions giving rise to the Collateral shall
conform in all respects to the applicable state or federal consumer credit law.
DEBTOR SHALL HOLD HARMLESS AND INDEMNIFY SECURED PARTY AGAINST ANY COST, LOSS,
OR EXPENSE INCLUDING ATTORNEY'S FEES, ARISING FROM DEBTOR'S BREACH OF THIS
COVENANT.

      4.21 CHANGE OF NAME. Debtor shall not change its name (or any assumed name
or other name under which Debtor does business) or its corporate structure
unless at least thirty (30) days prior to the effective date of any such name
change, Debtor gives Secured Party written notice of such intended name change
and the new name or any change in its corporate structure. Debtor will not
change its principal place of business, chief executive office, or the place
where it keeps its books and records unless Debtor (i) shall have given Secured
Party thirty (30) days prior written notice thereof, and (ii) shall have taken
all action deemed necessary or desirable by Secured Party to cause the Security
Interest to be and remain perfected with the priority required by this
Agreement. Debtor shall execute all such documents and agreements (including
without limitation security agreements, financing statements, and amendments to
financing statements) as Secured Party may reasonably request in connection with
any such name change

      4.22 NOTATION ON TITLE CERTIFICATES. If certificates of title are issued
or outstanding with respect to any of the Collateral, Debtor will cause the
Security Interest to be properly noted therein.

      4.23 POWER OF ATTORNEY. Debtor appoints Secured Party as Debtor's
attorney-in-fact with full power in Debtor's name and behalf to do every act
which Debtor is obligated to do or may be required to do hereunder; however,
nothing in this section shall be construed to obligate Secured Party to take any
action hereunder.

      4.24 DEBTOR'S WAIVERS. Debtor waives notice of the creation, advance,
increase, existence, extension, or renewal of, and of any indulgence with
respect to, the Indebtedness; waives notice of intent to accelerate, notice of
acceleration, notice of intent to demand, presentment, demand, notice of
dishonor, and protest; waives notice of the amount of the Indebtedness
outstanding at any time, notice of any change in financial condition of any
person liable for the Indebtedness or any part thereof, notice of any Event of
Default, and all other notices respecting the Indebtedness; and agrees that
maturity of the Indebtedness and any part thereof may be accelerated, extended,
or renewed one or more times by Secured Party in its discretion, without notice
to Debtor.

SECURITY AGREEMENT                 Page 5
<PAGE>
      4.25 OTHER PARTIES AND OTHER COLLATERAL. No renewal or extension of or any
other indulgence with respect to the Indebtedness or any part thereof, no
release of any security, no release of any person (including any maker,
endorser, guarantor, or surety) liable on the Indebtedness, no delay in
enforcement of payment, and no delay or admission or lack of diligence or care
in exercising any right or power with respect to the Indebtedness or any
security therefor or guaranty thereof or under this Agreement shall in other
manner impair or affect the rights of Secured Party under the law, under this
Agreement, or under any other agreement pertaining to the other security for the
Indebtedness, before foreclosing upon the Collateral for the purpose of paying
the Indebtedness. Debtor waives any right to the benefit of or to require or
control application of any other security or proceeds thereof, and Debtor agrees
that Secured Party shall have no duty or obligation to Debtor to apply to the
Indebtedness any such other security or proceeds thereof.

                                    ARTICLE V
                       RIGHTS AND POWERS OF SECURED PARTY

      5.1 GENERAL. Secured Party before or after default without liability to
Debtor may: obtain from any person information regarding Debtor or Debtor's
business, which information any such person also may furnish without liability
to Debtor; require Debtor to give possession or control of any Collateral to
Secured Party; endorse as Debtor's agent any instruments, documents, or chattel
paper in Collateral or representing proceeds of Collateral; contact account
debtors directly to verify information furnished by Debtor; take control of
proceeds; release Collateral in its possession to any Debtor temporarily or
otherwise; require additional collateral; reject as unsatisfactory any property
hereafter offered by Debtor as Collateral; set standards from time to time to
govern what may be used as after-acquired collateral; designate, from time to
time, a certain percent of the Collateral as the loan value and require Debtor
to maintain the Indebtedness at or below such figure; take control of funds
generated by the Collateral, such as cash dividends, interest, and proceeds or
refunds from insurance, and use same to reduce any part of the Indebtedness and
exercise all other rights which an owner of such Collateral may exercise, except
the right to vote or dispose of Collateral before an Event of Default; at any
time transfer any of the Collateral or evidence thereof into its own name of
that of its nominee; and demand, collect, convert, redeem, receipt for, settle,
compromise, adjust, sue for, foreclose, or realize upon Collateral, in its own
name or in the name of Debtor, as Secured Party may determine in its sole and
absolute discretion. Secured Party shall not be liable for failure to collect
any account or instrument, or for any act or omission on the part of the Secured
Party, its officers, agents, or employees, except willful misconduct. The
foregoing rights and powers of Secured Party will be in addition to, and not a
limitation upon, any rights and powers of Secured Party given by law, elsewhere
in this Agreement, or otherwise. If Debtor fails to maintain any required
insurance, to the extent permitted by applicable law Secured Party may (but is
not obligated to) purchase single interest insurance coverage for the Collateral
which insurance may at Secured Party's option (i) protect only Secured Party and
not provide any remuneration or protection for Debtor directly and (ii) provide
coverage only after the Indebtedness has been declared due as herein provided.
The premiums for any such insurance purchased by Secured Party shall be a part
of the Indebtedness and shall bear interest as provided in Section 1.2(d) above.

                                   ARTICLE VI
                                     DEFAULT

      6.1 EVENTS OF DEFAULT. The following are events of default under this
Agreement ("Events of Default"):

            (a) default in the timely payment of any part of the Indebtedness or
in performance or observance of the terms and conditions herein or in any other
agreement between Debtor and Secured Party, including any default under the
terms of that certain Credit Agreement dated February 20th, 1997, between Debtor
and Secured Party, relating to the Indebtedness;

            (b) any warranty, representation, or statement made or furnished to
Secured Party by Debtor proves to have been false in any material respect when
made or furnished;

            (c) acceleration of the maturity of debt of Debtor to any other
person;

SECURITY AGREEMENT                 Page 6
<PAGE>
            (d) substantial change in any fact warranted or represented in this
Agreement or in any other agreement between Debtor and Secured Party or in any
statement, schedule, or other writing furnished in connection therewith;

            (e) sale, loss, theft, destruction, encumbrance, or transfer of any
Collateral in violation hereof, or substantial damage to any Collateral;

            (f) belief by Secured Party that the prospect of payment of the
Indebtedness or performance of this Agreement is impaired;

            (g) death, incapacity, dissolution, merger, or consolidation,
termination of existence, insolvency or business failure of Debtor or any person
liable on the Indebtedness; commencement of proceedings for the appointment of a
receiver for any property of Debtor; commencement of any proceeding under any
bankruptcy or insolvency law by or against Debtor (or any corporate action shall
be taken to effect same), or any partnership of which Debtor is a partner, or by
or against any person liable upon the Indebtedness or any part thereof, or
liable upon Collateral;

            (h) levy on, seizure, or attachment of any property of Debtor;

            (i) a judgment against Debtor in excess of $500,000.00 becomes
final; or

            (j) any liability or agreement of third parties to Debtor or on the
Collateral shall not be paid or performed in accordance with the terms thereof.

      6.2 REMEDIES OF SECURED PARTY UPON DEFAULT. When an Event of Default
occurs, and at any time thereafter, Secured Party without notice or demand may
declare the Indebtedness in whole or part immediately due and may enforce
payment of the same and exercise any rights under the Texas UCC, rights and
remedies of Secured Party under this Agreement, or otherwise. Secured Party may
require Debtor to assemble the Collateral and make it available to Secured Party
at a place which is reasonably convenient to both parties. Unless the Collateral
is perishable or threatens to decline speedily in value or is of a type
customarily sold on a recognized market, Secured Party will give Debtor
reasonable notice of the time and place of any public sale thereof or of the
time after which any private sale or other intended disposition thereof is to be
made. Expenses of retaking, holding, preparing for sale, selling, leasing, or
the like shall include Secured Party's reasonable attorney's fees and legal
expenses. Secured Party shall be entitled to immediate possession of all books
and records evidencing any accounts or general intangibles or pertaining to
chattel paper covered by this Agreement and shall have the authority to enter
upon any premises upon which any of the same, or any Collateral, may be situated
and remove the same therefrom without liability. Secured Party may surrender any
insurance policies in Collateral and receive the unearned premium thereon.
Debtor shall be entitled to any surplus after payment of the Indebtedness and
shall be liable to Secured Party for any deficiency. The process of any
disposition after default available to satisfy the Indebtedness shall be applied
to the Indebtedness in such order and in such manner as Secured Party in its
discretion shall decide. If, in the opinion of Secured Party, there is any
question that a public sale or distribution of any Collateral will violate any
state or federal securities law, Secured Party (i) may offer and sell securities
privately to purchasers who will agree to take them for investment purposes and
not with a view to distribution and who will agree to imposition of restrictive
legends on the certificates representing the security, or (ii) may sell such
securities in an intrastate offering under Section 3(a)(11) of the Securities
Act of 1933, and no sale so made in good faith by Secured Party shall be deemed
to be not "commercially reasonable" because so made.

                                   ARTICLE VII
                                     GENERAL

      7.1 PARTIES BOUND. Secured Party's rights under this Agreement and the
Security Interest shall inure to the benefits of its successors and assigns, and
in the event of any assignment or transfer of any of the Indebtedness or the
Collateral, Secured Party thereafter shall be fully discharged from any
responsibility with respect to the Collateral so assigned or transferred, but
Secured Party shall retain all rights and powers hereby given with respect to
any of the Indebtedness or Collateral not so assigned or transferred. All
representations,

SECURITY AGREEMENT                 Page 7
<PAGE>
warranties, and agreements of Debtor if more than one are joint and several, and
all shall be binding upon the personal representatives, heirs, successors, and
assigns of Debtor.

      7.2 WAIVER. No delay of Secured Party in exercising any power or right
shall operate as a waiver thereof; nor shall any single or partial exercise of
any power or right preclude other or further exercise thereof or the exercise of
any other power or right. No waiver by Secured Party of any right hereunder of
any default by Debtor shall be binding upon Secured Party unless in writing, and
no failure by Secured Party to exercise any power or right hereunder or waiver
of any default by Debtor shall operate as a waiver of any other or further
exercise of such right or power of any further default.

      7.3 AGREEMENT CONTINUING. This Agreement shall constitute a continuing
agreement, applying to all future as well as existing transactions, whether or
not of the character contemplated at the date of this Agreement, and if all
transactions between Secured Party and Debtor shall be closed at any time, shall
be equally applicable to any new transactions thereafter. Provisions of this
Agreement, unless by their terms exclusive, shall be in addition to other
agreements between the parties.

      7.4 DEFINITIONS. Unless the context indicates otherwise, definitions in
the Texas UCC apply to words and phrases in this Agreement; if Texas UCC
definitions conflict, Chapter 9 definitions apply.

      7.5 NOTICE. Notice shall be deemed reasonable if mailed postage prepaid at
least 5 days before the related action (or if the Texas UCC elsewhere specifies
a longer period, such longer period) to Debtor's address shown above.

      7.6 INTEREST. No agreement relating to the Indebtedness shall be construed
to be a contract for or to authorize charging or receiving, or require the
payment or permit the collection of, interest at a rate or in an amount above
that authorized by law. Interest payable under any agreement above that
authorized by law shall be reduced automatically to the highest amount permitted
by law.

      7.7 MODIFICATIONS. No provision hereof shall be modified or limited except
by a written agreement expressly referring hereto and to the provisions so
modified or limited and signed by Debtor and Secured Party, nor by course of
conduct, usage of trade, or by the law merchant.

      7.8 SEVERABILITY. The unenforceability of any provision of this Agreement
shall not affect the enforceability or validity of any other provision.

      7.9 GENDER AND NUMBER. Where appropriate, the use of one gender shall be
construed to include the others or any of them; and the singular number shall be
construed to include the plural, and vice versa.

      7.10 APPLICABLE LAW AND VENUE. THIS AGREEMENT SHALL BE CONSTRUED ACCORDING
TO THE LAWS OF THE STATE OF TEXAS AND THE LAWS OF THE UNITED STATES OF AMERICA
APPLICABLE TO TRANSACTIONS IN THE STATE OF TEXAS. Except at otherwise stated,
this Agreement and the Security Interest shall be construed in accordance with
the Texas Uniform Commercial Code [Texas Business and Commerce Code ss. 1.01, ET
SEQ. ("Texas UCC"). This Agreement is performable by Debtor in the county of
Secured Party's address set out above.

      7.11 FINANCING STATEMENT. A carbon, photographic, or other reproduction of
this security agreement or any financing statement covering the Collateral shall
be sufficient as a financing statement.

      7.12 LIMITATIONS OF LAW. If any law prohibits or limits any charge or
expense provided for in this Agreement in connection with any loan secured
hereby, such charge or expense will not be made or incurred in connection with
such loan beyond the limits permitted by such law.

      EXECUTED as of the 20th day of February, 1997.
