                      WHERE YOU CAN FIND MORE INFORMATION
 
   
     We have filed with the SEC a registration statement on Form S-3 (Reg. No.
333-67665) with respect to the securities we are offering. This prospectus does
not contain all the information contained in the registration statement,
including its exhibits and schedules. You should refer to the registration
statement, including the exhibits and schedules, for further information about
us and the securities we are offering. Statements we make in this prospectus
about certain contracts or other documents are not necessarily complete. When we
make such statements, we refer you to the copies of the contracts or documents
that are filed as exhibits to the registration statement, because those
statements are qualified in all respects by reference to those exhibits. The
registration statement, including exhibits and schedules, is on file at the
offices of the SEC and may be inspected without charge.
    
 
     We file annual, quarterly and special reports, proxy statements and other
information with the SEC. Our SEC filings, including the registration statement,

public reference rooms in Washington, D.C.; New York, New York; and Chicago,
Illinois. Please call the SEC at 1-800-SEC-0330 for further information about
the public reference rooms.
 
     SEC rules allow us to include some of the information required to be in the
registration statement by incorporating that information by reference to
documents we file with them. That means we can disclose important information to
you by referring you to those documents. The information incorporated by
reference is an important part of this prospectus, and information that we file
later with the SEC will automatically update and supersede this information. We
incorporate by reference the documents listed below and any future filings made

BUSINESS
    
 
   
     We are the world's largest onshore oil and gas well service and workover
company based on the number of rigs we own and available industry data. We
provide a complete range of rig-based well maintenance, workover, completion,
recompletion, contract drilling and non-rig ancillary well services to major and
independent oil and gas companies. We believe that we have the most
comprehensive array of services of any participant in the market and have
differentiated ourself from our competitors by our position as a single-source
provider of multiple well-head based services and products across multiple
geographic regions. In addition to maintenance and workover services, we provide
services that include:
    
 
     - the completion of newly drilled wells;
 
     - the recompletion of existing wells (including horizontal recompletions);
 
   
     - plugging and abandonment of wells at the ends of their useful lives;
    
 
     - oilfield fluid and equipment transportation;
 
     - oilfield fluid storage and disposal services;
 
     - fishing and rental tools;
 
     - wireline services;
 
     - air drilling;
 
     - hot oiling; and
 
     - production testing services.
 
   
     Areas of Operation. Our principal operating regions in the United States
include West Texas and Eastern New Mexico, the Gulf Coast, Oklahoma, Michigan,
the Appalachian Basin, the Rocky Mountains, the Ark La Tex region, the Four
Corners area and California. We also operate in Argentina and have limited
operations in Ontario, Canada.
    
 
   
     Operating Assets. We estimate that our share of the domestic onshore well
service rig fleet is approximately 33% based on the number of rigs we own and
available industry data. Our operating assets consist of approximately 1,420
well service and workover rigs, 75 drilling rigs and 1,130 oil field trucks.
    
 
   
     Acquisitions. We have pursued an acquisition strategy designed to
consolidate a highly fragmented industry that is primarily comprised of small,
regional well service companies. Over the last three years, we have completed
over 50 acquisitions, for an aggregate consideration of approximately $807
million. In September 1998, we purchased Dawson Production Services, Inc., which
was the third largest onshore oil and gas well service and workover company in
the United States based on the number of rigs they owned and available industry
data. Our share of the domestic onshore well service rig fleet has increased
from approximately 3% at February 1996 to approximately 33% currently.
    
 
   
     As a result of our consolidation strategy, we have realized significant
revenue and EBITDA growth. Our revenues have grown from $44.7 million in fiscal
1995 to $645.4 million on a pro forma basis in fiscal 1998. In the same time
period, EBITDA has grown from approximately $7.5 million to $137.8 million on a
pro forma basis.

COMPANY STRENGTHS
    
 
   
     Market Leadership. Based on total well service rig count, we are nearly
twice as large as our next largest competitor and over 15 times larger than our
second largest domestic onshore competitor. Our market leadership enables us to
enter into strategic alliances with major and independent oil and gas producers,
resulting in a more predictable and reliable revenue stream. Additionally, we
have achieved a lower cost structure through operational efficiencies, improved
purchasing power and lower general and administrative costs.
    
 
   
     Full Service Line. Exploration and production companies increasingly are
demanding a single source provider for well and workover services. We believe
the breadth and reliability of our services positions us as the service provider
of choice in our operating regions.
    
 
   
     Recurring Baseline Business. We believe a majority of our revenues are
derived from maintenance-related expenditures by oil and gas producers. These
expenditures are made to maintain current production from existing wells.
Because maintenance-related services are necessary for continued, efficient
production, they are less likely to be cut or deferred than other services, such
as exploration and development, drilling and completion services. As a result,
the need for maintenance-related services generally is less sensitive to changes
in oil and gas prices than non maintenance-related services.
    
 
   
     Diversified Operations. We are geographically diversified, with a presence
in all major onshore oil and gas producing regions in the continental United
States. Although the range of services varies from region to region, we
generally provide a full range of well services in each region. We have over
1,000 customers, including large and independent oil and gas producers as well
as smaller, regional operators. For fiscal 1998, no single customer accounted
for more than 5% of our revenues.
    
 
   
BUSINESS STRATEGY
    
 
   
     Our strategy is to achieve profitable growth by:
    
 
   
     Offering a Complete Range of Services. We seek to meet the demands of our
large and diverse customer base with a full service offering because customers
in our industry increasingly turn to single source providers for well and
workover rig services. This strategy allows us to cross-market our services and
to appeal to an even broader customer base by enhancing our position as a
"one-stop" source of well services. Our ability to cross-market additional
services to the customers of our acquired companies also has enhanced revenue
potential and increased operational efficiency. We believe our ability to be a
single source provider in multiple operating regions has increased our market
share, differentiated us from our competitors and provided greater recurring
business.
    
 
   
     Maximizing Efficiencies of Recent Acquisitions. The success of our
acquisition strategy depends on our ability to maximize the economies of scale
and synergies resulting from our increased size and to achieve reduced operating
costs through the consolidation process. The integration of our acquisitions in
the last three years has resulted in the elimination of excess personnel, office
facilities, regional facilities and yards, resulting in cost savings and
improved operating margins. We intend to continue to focus on cost reductions to
optimize future operating margins and cash flow.
    
 
   
     Making Selective Acquisitions. We have made substantial progress in our
strategy to consolidate the well service industry by acquiring the companies and
operations that we believed were best suited to our ongoing business plans. The
success of our consolidation efforts has resulted in fewer
    
 
                                        5
<PAGE>   8
 
   
opportunities to make significant well service industry acquisitions.
Nonetheless, we may make niche acquisitions that offer the opportunity for
geographic expansion and product line extension.
    
 
   
RECENT DEVELOPMENTS
    
 
   
     In response to the current industry downturn caused by historically low oil
and gas prices and the resulting slowdown in our business, on December 7, 1998,
we announced a company-wide restructuring plan to reduce operating costs beyond
those achieved through our consolidation efforts. The plan involved a reduction
in the size of our management and on-site work force, salary reductions of up to
20% for senior management, the combination of previously separate operating
divisions and the elimination of redundant divisional overhead and facilities.
We currently expect approximately $9 million of annualized cost savings from
this plan within the next six months. The restructuring plan resulted in a
one-time pretax charge to earnings of approximately $6.7 million in the second
fiscal quarter ending December 31, 1998. In addition, we have completed the
integration of Dawson into our business, from which we expect annualized cost
savings of approximately $12 million. In connection with the Dawson acquisition,
we anticipate we will incur an additional, extraordinary pretax charge of
approximately $6.1 million in the third fiscal quarter ending March 31, 1999,
expensing debt issuance costs and fees related to the syndication of our bridge
credit facility.
    
 
   
     Due to weakness of oil and gas prices, demand for our services declined
throughout the second fiscal quarter ending December 31, 1998 and has continued
to decline during the third fiscal quarter ending March 31, 1999. By December
31, 1998, oilfield service industry activities were at depressed levels because
many oil companies either reached their 1998 capital budget targets or reduced
spending in light of the current commodity price environment. If oil and gas
prices remain at or above the levels encountered at the end of calendar 1998, we
believe average monthly oilfield services spending by oil and gas companies in
calendar 1999 will be at levels greater than at the end of calendar 1998 as
companies implement their 1999 capital budgets, although much of their spending
could be weighted toward the end of the calendar year. Should this scenario
materialize, our results, including EBITDA and financial condition could be
materially and adversely impacted in our third and fourth fiscal quarters.
    
 
   
     In light of current market conditions, we recently renegotiated certain
financial covenants in our credit facility to levels that we believe will allow
us to remain in compliance for the remainder of calendar 1999. However, if
demand for our services does not increase and our operating performance does not
improve from the levels of November and December of 1998, we may require further
covenant relief or waivers from our lenders during calendar 1999 to remain in
compliance with certain of our financial covenants.
    
 
   
     We believe if demand for our services increases, our aggressive
restructuring plan and other cost saving initiatives have positioned us for
strong performance. No assurance can be given, however, that we will be able to
realize the anticipated cost savings from the restructuring plan or that demand
for our services will return to or exceed historical levels.

                           FORWARD-LOOKING STATEMENTS
    
 
   
     The statements made in this prospectus or in the documents we have
incorporated by reference that are not statements of historical fact are
"forward looking statements" within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
Forward-looking statements generally can be identified by the use of
forward-looking terminology such as "may," "will," "expect," "intend,"
"estimate," "anticipate" or "believe," or similar terminology.
    
 
   
     The forward-looking statements include discussions about business strategy
and expectations concerning market position, future operations, margins,
profitability, liquidity and capital resources, and statements concerning the
integration into our business of the operations we have acquired. Although we
believe that the expectations in such statements are reasonable, we cannot give
any assurance that those expectations will be correct.
    
 
   
     We caution you not to place undue reliance on these forward-looking
statements, which speak only as of the date of this prospectus.
    
 
   
     Our operations are subject to several uncertainties, risks and other
influences, many of which are outside our control and any of which could
materially affect our results of operations and ultimately prove the statements
we make to be inaccurate.
    
 
   
     Important factors that could cause actual results to differ materially from
our expectations are discussed under the heading "Risk Factors" and elsewhere in
this prospectus.
    
 
                                  RISK FACTORS
 
     You should consider the following risk factors and other information in
this prospectus before deciding to buy our securities.
 
   
RISKS ASSOCIATED WITH OIL AND GAS INDUSTRY -- OUR BUSINESS IS DEPENDENT ON
CONDITIONS IN THE OIL AND GAS INDUSTRY, ESPECIALLY THE PRODUCTION EXPENDITURES
OF OIL AND GAS COMPANIES.
    
 
   
     The demand for our services is directly influenced by current and
anticipated oil and gas prices, oil and gas production costs, and government
regulation and conditions in the worldwide oil and gas industry, and
particularly on the level of development, exploration and production activity
of, and corresponding spending by, oil and gas companies. Most of our operations
are in the United States where the demand for well servicing and related
services currently is depressed in many markets because of weak oil prices,
which currently are at a twelve-year low. Continued weakness in oil and gas
prices may cause lower day rates and lower utilization of available well service
equipment. In addition, when oil prices are weak, fewer wells are drilled,
resulting in less drilling and less maintenance work for us. Periods of
diminished or weakened demand may continue to occur. In light of these and other
factors relating to the oil and gas industry, our historical operating results
may not be indicative of future performance. In addition, reductions in oil
prices can result in a reduction in the trading prices of our securities, even
if the reduction in oil prices does not affect our business generally.

SUBSTANTIAL LEVERAGE -- OUR SUBSTANTIAL INDEBTEDNESS COULD ADVERSELY AFFECT OUR
FINANCIAL HEALTH AND PREVENT US FROM FULFILLING OUR OBLIGATIONS UNDER OUR
CURRENT INDEBTEDNESS.
    
 
   
     We have a significant amount of indebtedness. The following chart shows
certain important credit statistics:
    
 
   
<TABLE>
<CAPTION>
                                                               DECEMBER 31, 1998
                                                               -----------------
                                                                  (DOLLARS IN
                                                                  THOUSANDS)
<S>                                                            <C>
Total debt..................................................       $849,381
Stockholders' equity........................................        144,622
Debt to equity ratio........................................         5.87:1
</TABLE>
    
 
   
     Our substantial indebtedness could:
    
 
   
     - increase our vulnerability to general adverse economic and industry
       conditions;
    
 
   
     - limit our ability to fund future working capital, capital expenditures
       and other general corporate requirements;
    
 
   
     - require us to dedicate a substantial portion of our cash flow from
       operations to payments on our indebtedness, thereby reducing the
       availability of our cash flow to fund working capital, capital
       expenditures and other general corporate purposes;
    
 
   
     - limit our flexibility in planning for, or reacting to, changes in our
       business and the industry in which we operate;
    
 
   
     - place us at a competitive disadvantage compared to our competitors that
       have less debt; and
    
 
   
     - limit, along with the financial and other restrictive covenants in our
       credit facility, among other things, our ability to borrow additional
       funds. Our failure to comply with these covenants could result in an
       event of default which, if not cured or waived, could have a material
       adverse effect on us.
    
 
   
ADDITIONAL BORROWINGS AVAILABLE  -- DESPITE CURRENT INDEBTEDNESS LEVELS, WE AND
OUR SUBSIDIARIES STILL MAY BE ABLE TO INCUR SUBSTANTIALLY MORE DEBT. THIS COULD
FURTHER INCREASE THE RISKS DESCRIBED ABOVE.
    
 
   
     We and our subsidiaries may be able to incur substantial additional
indebtedness in the future. Our credit facility currently permits additional
borrowings of up to approximately $30 million. If new debt is added to our and
our subsidiaries' current debt levels, the related risks that we and they now
face could intensify.
    
 
   
ABILITY TO SERVICE DEBT -- TO SERVICE OUR INDEBTEDNESS, WE WILL REQUIRE A
SIGNIFICANT AMOUNT OF CASH. OUR ABILITY TO GENERATE CASH DEPENDS ON MANY FACTORS
BEYOND OUR CONTROL.
    
 
   
     Our ability to make payments on and to refinance our indebtedness, and to
fund planned capital expenditures will depend on our ability to generate cash in
the future. This, to a certain extent, is subject to general economic,
financial, competitive, legislative, regulatory and other factors that are
beyond our control.
    
 
   
     We cannot assure you that our business will generate sufficient cash flow
from operations to service our outstanding debt, that currently anticipated cost
savings and operating improvements will be realized or that future borrowings
will be available to us under our credit facility in an amount
    
 
                                        9
<PAGE>   12
 
   
sufficient to enable us to pay our indebtedness or to fund our other liquidity
needs. We may need to refinance all or a portion of our indebtedness on or
before maturity. We cannot assure you that we will be able to refinance any of
our indebtedness, including our credit facility, on commercially reasonable
terms or at all.
    
 
   
RISKS ASSOCIATED WITH INTEGRATION OF ACQUISITIONS -- WE HAVE PURSUED, AND INTEND
TO CONTINUE TO PURSUE, ACQUISITIONS. OUR BUSINESS MAY BE ADVERSELY AFFECTED IF
WE CANNOT EFFECTIVELY INTEGRATE ACQUIRED OPERATIONS.
    
 
   
     One of our business strategies has been to acquire operations and assets
that are complementary to our existing businesses. In the last twelve months,
our acquisitions have doubled the number of well service rigs we own. Our
revenues have grown from $44.7 million in fiscal 1995 to $645.6 million on a pro
forma basis in fiscal 1998, largely as a result of acquisitions. Acquiring
operations and assets involves financial, operational and legal risks. These
risks include the difficulty of assimilating operations, systems and personnel
of the acquired businesses and maintaining uniform standards, controls,
procedures and policies. Any future acquisitions would likely result in an
increase in expenses. In addition, competition from other potential buyers could
cause us to pay a higher price than we otherwise might have to pay and reduce
our acquisition opportunities. Moreover, our past success in making acquisitions
and in integrating acquired businesses does not necessarily mean we will be
successful in making acquisitions and integrating businesses in the future.
    
 
   
OPERATING RISKS; INSURANCE -- OUR BUSINESS COULD BE ADVERSELY AFFECTED BY
CERTAIN OPERATING RISKS, AND OUR INSURANCE MAY NOT BE ADEQUATE TO COVER ALL
LOSSES OR LIABILITIES WE MIGHT INCUR IN OUR OPERATIONS.
    
 
   
     Our operations are subject to many hazards. These hazards include
explosions, blow-outs, reservoir damage, loss of well control, cratering, fires
and damage to the environment. In addition, we are subject to seasonal risks
caused by adverse weather conditions such as rain and flooding, high winds and
severe winter storms. Operations in northern regions are subject to limitations
on transporting equipment during the spring thaw. These hazards and risks could
cause the suspension of operations, damage to or destruction of our equipment
and the property of others and injury or death to field personnel. Like most
companies in our industry, we have experienced some of these incidents in our
operations. The frequency and severity of these incidents affect our operating
costs and our relationships with customers, employees and regulators. Any
significant increase in the frequency or severity of such incidents, or the
general level of compensation awards, could affect our ability to obtain
insurance and could have a material adverse effect on our business. We have
insurance, customary in the industry, to protect against these liabilities.
However, this insurance is capped at $50 million per incident and does not
provide coverage for all liabilities. Our insurance may not be adequate to cover
all losses or liabilities that we might incur in our operations. To the extent
our liability for any particular loss or liability exceeds the $50 million cap,
we would incur costs for the excess. Moreover, we may not be able to maintain
insurance at adequate levels or at reasonable rates and particular types of
coverage may not be available in the future.
    
 
   
COMPETITION
    
 
   
     We experience intense competition in our markets. Certain of our
competitors have greater financial and other resources than we do.
    
 
                                       10
<PAGE>   13
 
   
POTENTIAL LABOR SHORTAGE -- WE HISTORICALLY HAVE EXPERIENCED A HIGH EMPLOYEE
TURNOVER RATE. ANY DIFFICULTY WE EXPERIENCE REPLACING OR ADDING WORKERS COULD
ADVERSELY AFFECT OUR BUSINESS.
    
 
   
     We historically have experienced an annual employee turnover rate of over
50%. The high turnover rate is caused by the nature of the work, which is
physically demanding and performed outdoors. As a result, workers may choose to
pursue employment in fields that offer a more desirable work environment at wage
rates that are competitive with ours. Although we currently are downsizing our
workforce, we cannot assure that at times of high demand we will be able to
recruit and train workers. Potential inability or lack of desire by workers to
commute to our facilities and job sites and competition for workers from other
industries are factors that could affect our ability to attract workers. We
believe that our wage rates are competitive with the wage rates of our
competitors and other potential employers. A significant increase in the wages
other employers pay could result in a reduction in our workforce, increases in
our wage rates, or both. Either of these events could diminish our profitability
and growth potential.
    
 
   
GOVERNMENTAL REGULATION AND ENVIRONMENTAL MATTERS -- WE MAY BECOME LIABLE FOR
PENALTIES UNDER A VARIETY OF ENVIRONMENTAL LAWS AND GOVERNMENT REGULATIONS EVEN
IF WE DO NOT CAUSE ANY ENVIRONMENTAL PROBLEMS. CERTAIN CHANGES IN ENVIRONMENTAL
LAWS AND GOVERNMENT REGULATIONS COULD ADVERSELY AFFECT OUR BUSINESS.
    
 
   
     Our operations are subject to foreign, federal, state and local laws and
regulations relating to protection of the environment, natural resources, health
and safety, waste management and transportation of waste and other materials
including hydrocarbons and chemicals. Our fluid services include injection
operations that pose certain risks of environmental liability. Although we
monitor the injection process, the possibility exists of leakage to surface or
subsurface soils or groundwater, which could result in cancellation of well
operations, fines and penalties, expenditures for remediation, and liability for
property damages and personal injuries. Sanctions for noncompliance with
applicable environmental laws and regulations also may include administrative,
civil and criminal penalties, revocation of permits and corrective action
orders. In addition, our operations may be subject to potential liability for
environmental clean up at currently or previously owned or operated properties
or off-site locations where we sent, disposed of, or arranged for disposal of
hazardous materials. A party can be liable for environmental damage without
regard to its negligence or fault. Therefore, we could incur liability based on
the conduct of others, or for acts that were lawful at the time we performed
them. Environmental laws have become more stringent over the years. The
modification or interpretation of existing laws or regulations, the adoption of
new laws or regulations or the more vigorous enforcement of environmental laws
or regulations could curtail exploratory or development drilling for oil and gas
and could limit well servicing opportunities.
    
 
   
FOREIGN INVESTMENTS -- OUR FOREIGN BUSINESS EXPOSES US TO RISKS RELATING TO
INCREASED REGULATION AND POLITICAL OR ECONOMIC INSTABILITY WITHIN CERTAIN
FOREIGN COUNTRIES.
    
 
   
     We have investments and may make additional investments in Argentina and
Canada. We may make other investments outside the United States. Foreign
investments are subject to risks relating to the political, social and economic
structures of those countries. Risks may include fluctuations in currency
valuation, expropriation, confiscatory taxation and nationalization, currency
conversion restrictions, increased regulation and approval requirements and
governmental policies limiting returns to foreign investors. In fiscal 1998, our
foreign operations accounted for less than 10% of our revenues.
    
 
                                       11
<PAGE>   14
 
   
DEPENDENCE ON KEY PERSONNEL -- OUR BUSINESS MAY BE ADVERSELY AFFECTED IF WE LOSE
OUR EXECUTIVE OFFICERS.
    
 
   
     We depend upon the performance of our executive officers. We have entered
into employment agreements with these executive officers that contain
non-compete provisions. Notwithstanding these agreements, we may not be able to
retain our executive officers and may not be able to enforce the non-compete
provisions in the employment agreements. We maintain key person life insurance
on the lives of certain of our offices, including our chief executive officer.
This insurance does not mean that the death or disability of one or more of them
would not adversely affect our operations.
    
 
   
YEAR 2000 ISSUE -- THE YEAR 2000 PROBLEM MAY ADVERSELY AFFECT OUR BUSINESS IF
OUR SUPPLIERS AND CUSTOMERS DO NOT ADEQUATELY ADDRESS THEIR YEAR 2000 CONCERNS.
    
 
   
     We currently are implementing a new integrated management information
system along with updated hardware that will replace most of our current
systems. The new management information system will be year 2000 compliant for
our systems as well as for those of our past and future acquisitions.
Implementation began in July 1998 and is scheduled to be substantially completed
by June 1999. Our new management information systems do not cover our Argentine
operations, but we have established a separate system, which is year 2000
compliant, that will be implemented in late 1999.
    
 
   
     We have not yet developed a plan to formally communicate with our
significant suppliers and customers to determine if those parties have
appropriate plans to remedy year 2000 issues when their systems interface with
our systems or otherwise have an impact on our operations. We do not anticipate
that this will have a material impact on our operations. However, there can be
no assurance that the systems of other companies on which we rely will be timely
converted, or that failure to successfully convert by another company, or
conversion that is incompatible with our systems, would not have an impact on
our operations. We currently do not have a contingency plan to cover any
unforeseen problems encountered that relate to the year 2000, but we intend to
produce one before the end of the current fiscal year.
    
 
   
     The cost of the new management information system is not anticipated to
have a material impact on our business. Although we are not aware of any
material operational issues or costs associated with preparing our internal
systems for the year 2000, there can be no assurance that there will not be a
delay in, or increased costs associated with, the implementation of the
necessary systems and changes to address the year 2000 issues.
    
 
   
     If we are unable to adequately address the year 2000 issue in a timely
manner, the worst case scenario would be that we could suffer significant
computer downtime, and billings, payments and collections would revert to manual
accounting records. In addition, the inability of our principal suppliers and
major customers to be year 2000 compliant could result in delays in product
deliveries from those suppliers and collection of accounts receivable.
    
 
   
SHARES ELIGIBLE FOR FUTURE SALE -- THE MARKET PRICE OF OUR COMMON STOCK COULD BE
ADVERSELY AFFECTED BY SALES OF SUBSTANTIAL AMOUNTS OF COMMON STOCK IN THE PUBLIC
MARKET OR THE PERCEPTION THAT SUCH SALES COULD OCCUR.
    
 
   
     As of March 1, 1999, we had 18,293,180 shares of common stock outstanding.
As of such date, approximately 10.3 million shares of common stock were issuable
upon the exercise of outstanding options, warrants and convertible securities.
The market price of the common stock could be
    
 
                                       12
<PAGE>   15
 
   
adversely affected by sales of substantial amounts of common stock in the public
market or the perception that such sales could occur.
    
 
   
VOLATILITY -- THE TRADING PRICE OF OUR SECURITIES COULD BE SUBJECT TO
SIGNIFICANT FLUCTUATIONS.
    
 
   
     The trading price of our common stock has been volatile. Factors such as
announcements of fluctuations in our or our competitors' operating results and
market conditions for oil and gas related stocks in general could have a
significant impact on the future trading prices of our securities. In
particular, the trading price of the common stock of many oil and gas companies
has experienced extreme price and volume fluctuations, which have at times been
unrelated to the operating performance of such companies whose stocks were
affected. In addition, the trading prices of our securities could be subject to
significant fluctuations in response to variations in our prospects and
operating results, which may in turn be affected by weakness in oil prices,
changes in interest rates and other factors. There can be no assurance that
these factors will not have an adverse effect on the trading prices of our
securities.
    
 
   
                                USE OF PROCEEDS
    
 
     Except as otherwise described in any prospectus supplement, the net
proceeds from the sale of securities will be used for general corporate
purposes, which may include refinancings of indebtedness, working capital,
capital expenditures, acquisitions and repurchases and redemptions of
securities.

prospectus. In the case of common stock, a prospectus supplement would include

include the number and terms of the warrants and the number of shares of common
stock issuable upon their exercise, including, the exercise price, the terms of
the offering, sale, duration and detachability of the warrants. In the case of
debt securities, the prospectus supplement would include, where applicable:
    
 
   
     - aggregate principal amount;
    
 
   
     - ranking as senior or subordinated debt securities;
    
 
   
     - maturity;
    
 
   
     - conversion terms;
    
 
   
     - rate or rates (or method of determination);

     - any exchangeability;
    
 
   
     - any terms for optional or mandatory redemption or repurchase, or payment
       of additional amounts or any sinking fund provisions;
    
 
   
     - whether or not such debt securities are guaranteed by our subsidiaries;
       and
    
 
   
     - any other specific terms of such debt securities.
    
 
   
     In the case of preferred stock, the information that will be set forth in a
prospectus supplement, will include:
    
 
   
     - specific designation;
    
 
   
     - number of shares;
    
 
   
     - liquidation value;
    
 
   
     - dividend rights;

     - voting rights;
    
 
   
     - other rights, including conversion or exchange rights, if any; and
    
 
   
     - any other specific terms.
    
 
     We may sell the securities through underwriters, agents or dealers or
directly to purchasers. A prospectus supplement will set forth the terms of each
specific offering, including the name or names of any underwriters or agents,
the purchase price of the securities and the proceeds to us from such sales, any
delayed delivery arrangements, any underwriting discounts and other items
constituting underwriters' compensation, any initial public offering price and
any discounts or concessions allowed or reallowed or paid to dealers. Any
initial public offering price and any discounts or concessions allowed or
reallowed or paid to dealers may be changed from time to time.
 
     If underwriters are used in the sale, the securities will be acquired by
the underwriters for their own account and may be resold from time to time in
one or more transactions, including negotiated transactions, at a fixed public
offering price or at varying prices determined at the time of sale. The
 
                                       14
<PAGE>   17
 
   
securities may be offered to the public either through underwriting syndicates
represented by one or more managing underwriters or directly by one or more
firms acting as underwriters. The underwriter or underwriters with respect to a
particular underwritten offering and, if an underwriting syndicate is used, the
managing underwriter or underwriters will be set forth on the cover of such
prospectus supplement. Unless otherwise set forth in the prospectus supplement,
the underwriters will be obligated to purchase all the securities if any are
purchased.
    
 
     During and after an offering through underwriters, the underwriters may
purchase and sell the securities in the open market. These transactions may
include overallotment and stabilizing transactions and purchases to cover
syndicate short positions created in connection with the offering. The
underwriters also may impose a penalty bid, under which selling concessions
allowed to syndicate members or other broker-dealers for the securities they
sell for their account may be reclaimed by the syndicate if the syndicate
repurchases the securities in stabilizing or covering transactions. These
activities may stabilize, maintain or otherwise affect the market price of the
securities then offered, which may be higher than the price that might otherwise
prevail in the open market, and, if commenced, may be discontinued at any time.
 
     We may sell the securities directly or through agents we designate from
time to time. Any agent involved in the offer or sale of the securities covered
by this prospectus will be named, and any commissions payable by us to an agent
will be set forth, in a prospectus supplement relating thereto. Unless otherwise
indicated in a prospectus supplement, any such agent will be acting on a best
efforts basis for the period of its appointment.
 
   
     If dealers are used in any of the sales of securities covered by this
prospectus, we will sell those securities to dealers as principals. The dealers
may then resell the securities to the public at varying prices the dealers
determine at the time of resale. The names of the dealers and the terms of the
transactions will be set forth in a prospectus supplement.
    
 
   
     We may sell the securities directly to institutional investors or others
who may be deemed to be underwriters within the meaning of the Securities Act
with respect to any sale thereof. The terms of any such sales will be described
in a prospectus supplement.
    
 
     If so indicated in a prospectus supplement, we will authorize agents,
underwriters or dealers to solicit offers from certain types of institutions to
purchase securities from us at the public offering price set forth in the
prospectus supplement pursuant to delayed delivery contracts providing for
payment and delivery on a specified date in the future. These contracts will be
subject only to those conditions set forth in the prospectus supplement, and the
prospectus supplement will set forth the commission payable for solicitation of
such contracts.
 
     Agents, dealers and underwriters may be entitled under agreements entered
into with us to indemnification by us against certain civil liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which such agents, dealers or underwriters may be required to make
in respect thereof. Agents, dealers and underwriters may be customers of, engage
in transactions with, or perform services on our behalf.

                         DESCRIPTION OF DEBT SECURITIES
 
   
     The debt securities will be:
    
 
   
     - our direct unsecured general obligations;
    
 
   
     - either senior debt securities or subordinated debt securities; and
    
 
   
     - will be issued under one or more separate indentures.
    
 
   
     Senior debt securities will be issued under a senior indenture and
subordinated debt securities will be issued under a subordinated indenture.
Senior debt securities and subordinated debt securities may be guaranteed by
certain of our subsidiaries. The debt securities issued may be convertible into
shares of our common stock.
    
 
     We have summarized selected provisions of the indentures below. The summary
is not complete. The forms of the indentures have been filed as exhibits to the
registration statement, and you should read the indentures for provisions that
may be important to you. In the summary, we have included references to section
numbers of the indentures so that you can easily locate those provisions.
Capitalized terms used in this summary have the meanings used in the indentures.
 
GENERAL
 
   
     - The Indentures do not limit the aggregate principal amount of debt
       securities that can be issued thereunder. (Section 301)
    
 
     - Debt securities may be issued in one or more series, each in an aggregate
       principal amount authorized by the Company before issuance, and may be in
       any currency or currency unit that we may designate. (Section 301)
 
   
     - Debt securities of a series may be issued in registered or global form.
       (Sections 201 and 203)
    
 
   
     - The Indentures do not limit the amount of other unsecured indebtedness or
       securities that we can issue.
    
 
     - The senior debt securities will rank equally with all of our other senior
       debt.
 
   
     - The subordinated debt securities will have a junior position to all of
       our senior debt. (Section 1301)
    
 
   
     We are a holding company that conducts all operations through our
subsidiaries. Holders of debt securities generally will have a junior position
to claims of creditors of our subsidiaries including trade creditors, debt
holders, secured creditors, taxing authorities, guaranty holders and any
preferred stockholders. At December 31, 1998, we did not have any outstanding
preferred stock and we and our subsidiaries had $849.4 million of outstanding
debt.
    
 
     A prospectus supplement and a supplemental indenture relating to any series
of debt securities being offered will include specific terms relating to the
offering. These terms will include some or all of the following:
 
     - the title and type of debt securities being offered;
 
     - the total principal amount of debt securities being offered;
 
     - the dates on which the principal of, and premium, if any, on the offered
       debt securities is payable;
 
     - the interest rate;
 
     - the date from which interest will accrue;
 
                                       16
<PAGE>   19
 
     - the interest payment dates;
 
     - any optional redemption periods;
 
     - any sinking fund or other provisions that would obligate us to repurchase
       or otherwise redeem the debt securities;
 
     - whether the debt securities will be convertible into shares of common
       stock or exchangeable for other of our securities, and if so, the terms
       of conversion or exchange;
 
     - events causing acceleration of maturity;
 
     - any provisions granting special rights to holders when the specified
       event occurs;
 
     - any changes to or additional events of default or covenants;
 
     - any special tax implications of the debt securities; and
 
   
     - any other terms of the debt securities. (Section 301)
    
 
   
GUARANTEES
    
 
   
     - Debt securities may be guaranteed by some, but not all, of our
       subsidiaries.
    
 
   
     - The subsidiaries that will guarantee any guaranteed debt securities are
       identified in the senior indenture and subordinated indenture relating
       thereto, each of which is an exhibit to this registration statement.
    
 
   
     - The guarantees will be general obligations of each guarantor.
    
 
   
     - The guarantors will jointly and severally guarantee any of our guaranteed
       debt securities.
    
 
   
     - Not all of our subsidiaries will be required to guarantee any guaranteed
       debt securities. In the event of a bankruptcy, liquidation or
       reorganization of any of the non-guarantor subsidiaries, the
       non-guarantor subsidiaries will pay the holders of their debt and their
       trade creditors before they will be able to distribute any of their
       assets to us. Although not all of our subsidiaries will guarantee any
       guaranteed debt securities, the guarantor subsidiaries generated over 90%
       of our consolidated revenues in the 12-month period ended December 31,
       1998.
    
 
   
     - The obligations of each guarantor under any subsidiary guarantee will be
       limited as necessary to prevent that subsidiary guarantee from
       constituting a fraudulent conveyance under applicable law.
    
 
   
     - A subsidiary guarantor may not consolidate with or merge into another
       company unless the surviving company assumes all of the obligations of
       that guarantor subsidiary pursuant to a supplemental indenture
       satisfactory to the trustee, and only if immediately after giving effect
       to the transaction, no default or event of default would exist.
    
 
DENOMINATIONS
 
     The debt securities will be issued in registered form of $1,000 each or
multiples thereof. (Section 302)
 
SUBORDINATION
 
     Under the subordinated indenture, payment of the principal, interest and
any premium on the subordinated debt securities generally will be subordinated
and junior in right of payment to the prior
 
                                       17
<PAGE>   20
 
payment in full of all senior debt. The subordinated indenture provides that no
payment of principal, interest or any premium on the subordinated debt
securities may be made in the event:
 
   
     - of any insolvency, bankruptcy or similar proceeding involving us or our
       property; or
    
 
   
     - we fail to pay the principal, interest, any premium or any other amounts
       on any senior debt when due. (Sections 1301 and 1303)
    
 
     The subordinated indenture will not limit the amount of senior debt that we
may incur.
 
   
     Senior debt is defined to include all notes or other unsecured evidences of
indebtedness including our guarantees for money we borrowed, not expressed to be
subordinate or junior in right of payment to any of our other indebtedness.
(Section 101)
    
 
EVENTS OF DEFAULT
 
     The following are Events of Default under each Indenture:
 
     - failure to pay principal or any premium on any debt security when due;
 
     - failure to pay any interest on any debt security when due, continued for
       30 days;
 
     - failure to deposit any mandatory sinking fund payment when due, continued
       for 30 days;
 
     - failure to perform any other covenant in the Indenture that continues for
       90 days after written notice;
 
     - certain events of bankruptcy, insolvency or reorganization; and
 
   
     - any other Event of Default as may be specified with respect to debt
       securities of such series. (Section 501)
    
 
     An Event of Default for a particular series of debt securities does not
necessarily constitute an Event of Default for any other series of debt
securities. The Trustee may withhold notice to the holders of debt securities of
any default (except in the payment of principal or interest) if the Trustee
considers withholding of notice to be in the best interest of the holders.
(Section 602)
 
                                       18
<PAGE>   21
 
   
ACCELERATION OF DEBT UPON AN EVENT OF DEFAULT
    
 
   
     If an Event of Default occurs:
    
 
   
     - either the Trustee or the holders of at least 25% in principal amount of
       the outstanding debt securities may declare the principal amount of all
       the debt securities of the applicable series to be due and payable
       immediately. (Section 502)
    
 
     - If this happens, subject to certain conditions, the holders of a majority
       in principal amount of the outstanding debt securities of such series can
       void the declaration. These conditions include the requirement that we
       have paid or deposited with the Trustee a sum sufficient to pay all
       overdue principal and interest payments on the series of debt securities
       subject to the default. (Section 502)
 
   
     If an Event of Default occurs due to certain events of bankruptcy,
insolvency or reorganization, the principal amount of the outstanding debt
securities of all series will become immediately due and payable without any
declaration or other act on the part of either Trustee or any holder. (Section
502)
    
 
     Depending on the terms of our indebtedness, an Event of Default under an
Indenture may cause a cross default on such other indebtedness.
 
   
DUTIES OF TRUSTEE
    
 
   
     Other than its duties in the case of default, the Trustee is not obligated
to exercise any of its rights or powers under any Indenture at the request,
order or direction of any holders unless the holders offer the Trustee
reasonable indemnity. (Section 603)
    
 
     If the holders provide reasonable indemnification, the holders of a
majority of principal amount of any series of debt securities may direct the
time, method and place of conducting any proceeding or any remedy available to
the Trustee, or exercising any power conferred upon the Trustee for any series
of debt securities. (Section 512)
 
COVENANTS
 
     Under the Indentures, we will:
 
     - pay the principal, interest and any premium on the debt securities when
       due;
 
     - maintain a place of payment;
 
   
     - deliver a report to the Trustee at the end of each fiscal year reviewing
       our obligations under the Indentures; and
    
 
   
     - deposit sufficient funds with any payment agent on or before the due date
       for any principal, interest or any premium. (Sections 1001, 1002, 1003
       and 1005)
    
 
MODIFICATION OF INDENTURES
 
   
     Under each Indenture, all rights and obligations of the holders may be
modified with the consent of the holders of a majority in aggregate principal
amount of the outstanding debt securities of each series effected by the
modification. No modification of the principal or interest payment terms and no
modification reducing the percentage required for modifications is effective
against any holder without its consent. (Sections 901 and 902)
    
 
                                       19
<PAGE>   22
 
CONSOLIDATION, MERGER AND SALE OF ASSETS
 
   
     Each Indenture generally permits a consolidation or merger between us and
another company. They also permit the sale by us of all or substantially all of
our property and assets. If this happens, the remaining or acquiring company
will assume all of our responsibilities and liabilities under the Indentures,
including the payment of all amounts due on the debt securities and performance
of the covenants in the Indentures. (Sections 801 and 802)
    
 
   
     We will only consolidate or merge with or into any other company or sell
all or substantially all of our assets according to the terms and conditions of
the Indentures. The remaining or acquiring company will be substituted for us in
the Indentures with the same effect as if it had been an original party to the
Indenture. Thereafter, the successor company may exercise our rights and powers
under any Indenture, in our name or in its own name. Any act or proceeding
required or permitted to be done by our board of directors or any of our
officers may be done by the board or officers of the successor company. If we
sell all or substantially all of our assets, we shall be released from all our
liabilities and obligations under any Indenture and under the debt securities.
(Sections 801 and 802)
    
 
DISCHARGE AND DEFEASANCE
 
   
     We and the subsidiary guarantors, if any, will be discharged from our
obligations under the debt securities of any series if we deposit with the
Trustee enough cash or government securities to pay the principal, interest, any
premium and any other sums due to the stated maturity date or redemption date of
the debt securities of the series. If this happens, the holders of the debt
securities of the series will not be entitled to the benefits of the Indenture
except for registration, transfer and exchange of debt securities and
replacement of lost, stolen or mutilated debt securities. (Section 401)
    
 
     Under federal income tax law as of the date of this prospectus, a discharge
may be treated as an exchange of the related debt securities. Each holder might
be required to recognize gain or loss equal to the difference between the
holder's cost or other tax basis for the debt securities and the value of the
holder's interest in the trust. Holders might be required to include as income a
different amount than would be includable without the discharge. Prospective
investors are urged to consult their own tax advisers as to the consequences of
a discharge, including the applicability and effect of tax laws other than the
federal income tax law.
 
PAYMENT AND PAYING AGENTS
 
     Principal, interest and premium on fully registered securities will be paid
at designated places. Payment will be made by check mailed to the person in
whose name the debt securities are registered on the day specified in the
Indentures or any prospectus supplement. Payments in other forms will be paid at
a place designated by us and specified in a prospectus supplement. (Section 307)
 
     Fully registered securities may be transferred or exchanged at the
corporate trust office of the Trustee or at any other office or agency
maintained by us for such purposes without the payment of any service charge
except for any tax or governmental charge. (Section 1002)
 
GLOBAL SECURITIES
 
     The Debt Securities of a series may be issued in the form of one or more
global certificates that will be deposited with a depositary identified in a
prospectus supplement. Unless otherwise stated in any prospectus supplement, The
Depository Trust Company, New York, New York ("DTC") will act
 
                                       20
<PAGE>   23
 
as depositary. Beneficial interests in global certificates will be shown on, and
transfers of global certificates will be effected only through, records
maintained by DTC and its participants.
 
                          DESCRIPTION OF CAPITAL STOCK
 
   
     As of March 1, 1999, our authorized capital stock was 100,000,000 shares,
which may be issued as either shares of preferred stock or common stock. As of
that date, we had 18,293,180 shares of common stock outstanding and no shares of
preferred stock outstanding.
    
 
COMMON STOCK
 
     Listing. Our common stock is listed on the New York Stock Exchange under
the symbol "KEG." Any additional common stock we issue will also be listed on
the NYSE.
 
     Dividends. Common stockholders may receive dividends when declared by the
board of directors. Dividends may be paid in cash, stock or another form.
However, certain of our existing debt agreements contain covenants that
currently restrict us from paying dividends. Additionally, in certain cases,
common stockholders may not receive dividends until we have satisfied our
obligations to any preferred stockholders.
 
     Fully Paid. All outstanding shares of common stock are fully paid and
non-assessable. Any additional common stock we issue will also be fully paid and
non-assessable.
 
     Voting Rights. Each share of common stock is entitled to one vote in the
election of directors and other matters. Common stockholders are not entitled to
preemptive or cumulative voting rights.
 
     Other Rights. We will notify common stockholders of any stockholders'
meetings according to applicable law. If we liquidate, dissolve or wind-up our
business, either voluntarily or not, common stockholders will share equally in
the assets remaining after we pay our creditors and preferred stockholders.
 
     Transfer Agent and Registrar. Our transfer agent and registrar is American
Stock Transfer & Trust Company, New York, New York.
 
PREFERRED STOCK
 
   
     The following description of the terms of the preferred stock sets forth
certain general terms and provisions of the preferred stock we may offer. If we
offer preferred stock, the specific designations and rights will be described in
a prospectus supplement and a description will be filed with the SEC.
    
 
     Our board of directors can, without approval of our stockholders, issue one
or more series of preferred stock. The board can also determine the number of
shares of each series and the rights, preferences and limitations of each series
including the dividend rights, voting rights, conversion rights, redemption
rights and any liquidation preferences of any series of preferred stock, the
number of shares constituting each series and the terms and conditions of issue.
In some cases, the issuance of preferred stock could delay a change in control
of the Company and make it harder to remove present management. Under certain
circumstances, preferred stock could also restrict dividend payments to holders
of our common stock.
 
     The transfer agent, registrar, and dividend disbursement agent for a series
of preferred stock will be named in a prospectus supplement. The registrar for
shares of preferred stock will send notices to
 
                                       21
<PAGE>   24
 
stockholders of any meetings at which holders of the preferred stock have the
right to elect directors or to vote on any other matter.
 
                            DESCRIPTION OF WARRANTS
 
     We may issue warrants, including warrants to purchase debt securities,
preferred stock, common stock or other securities. We may issue warrants
independently or together with other securities that may be attached to or
separate from the warrants. The terms of warrants will be set forth in a
prospectus supplement which will describe, among other things, the designation
of the warrants, the securities into which the warrants are exercisable, the
exercise price, the aggregate number of warrants to be issued, the principal
amount of securities purchasable upon exercise of each warrant, the price or
prices at which each warrant will be issued, the procedures for exercising the
warrants, the date upon which the exercise of warrants will commence, and the
expiration date, and any other material terms of the warrants.
 
                                 LEGAL MATTERS
 
   
     Certain legal matters relating to the validity of the common stock,
preferred stock, debt securities and warrants will be passed upon by Porter &
Hedges, L.L.P., Houston, Texas.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
   
     Section 2-418 of the Maryland General Corporation Law provides that a
corporation may indemnify any director made a party to any proceeding against
judgments, penalties, fines, settlements and reasonable expenses, unless it is
established that:
    
 
   
     - the act or omission of the director was material to the matter giving
       rise to the proceeding and was committed in bad faith or was a result of
       deliberate dishonesty;
    
 
   
     - the director actually received an improper personal benefit; or
    
 
     - in a criminal proceeding, the director had reasonable cause to believe
       the act or omission was unlawful.
 
     A director may not be indemnified in any proceeding charging improper
personal benefit if the director was adjudged to be liable on the basis that
personal benefit was improperly received and, in a derivative action, there
shall not be indemnification if a director has been adjudged liable to the
corporation. A director or officer of a corporation who has been successful in
the defense of any proceeding shall be indemnified against reasonable costs
incurred in such defense. Indemnification may not be made unless authorized for
a specific proceeding after determination by the board of directors, special
legal counsel or the stockholders that indemnification is permissible because
the director has met the requisite standard of conduct.
 
   
     Article Seventh of the Company's Amended and Restated Articles of
Incorporation, as amended (the "Charter"), provides that the Company shall
indemnify:
    
 
   
     - its directors and officers, whether serving the Company or at its request
       any other entity, to the full extent required or permitted by Maryland
       law, including the advance of expenses under the procedures and to the
       full extent permitted by law; and
    
 
     - other employees and agents to such extent as shall be authorized by the
       Board of Directors or the Company's By-Laws and be permitted by law.
 
     The foregoing rights of indemnification are not exclusive of any other
rights to which those seeking indemnification may be entitled. The Board of
Directors may take such action as is necessary to carry out these
indemnification provisions and is expressly empowered to adopt, approve and
amend from time to time such By-laws, resolutions or contracts implementing such
provisions or such
 
                                      II-1
<PAGE>   26
 
further indemnification arrangements as may be permitted by Maryland law.
Furthermore, no director or officer of the Company shall be personally liable to
the Company or its stockholders for monetary damages for breach of fiduciary
duty as a director or an officer, except to the extent that exculpation from
liability is not permitted under Maryland law as in effect when such breach
occurred. No amendment of the Charter or repeal of any of its provisions shall
limit or eliminate the limitations on liability provided to directors and
officers with respect to acts or omissions occurring prior to such amendment or
repeal.

ITEM 17. UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes:
 
          (1) To file, during any period in which offers or sales are being
     made, a post-effective amendment to this Registration Statement:
 
             (i) To include any prospectus required by section 10(a)(3) of the
        Securities Act of 1933;
 
             (ii) To reflect in the prospectus any facts or events arising after
        the effective date of the registration statement (or the most recent
        post-effective amendment thereof) which, individually or in the
        aggregate, represent a fundamental change in the information set forth
        in this registration statement;
 
             (iii) To include any material information with respect to the plan
        of distribution not previously disclosed in this registration statement
        or any material change to such information in this registration
        statement; provided, however, that subparagraphs (i) and (ii) do not
        apply if the information required to be included in a post-effective
        amendment by those paragraphs is contained in the periodic reports filed
        by the Registrant pursuant to Section 13 or Section 15(d) of the
        Securities and Exchange Act of 1934 that are incorporated by reference
        in this registration statement.
 
          (2) That for the purpose of determining any liability under the
     Securities Act of 1933, each such post-effective amendment shall be deemed
     to be a new registration statement relating to the securities offered
     herein, and the offering of such securities at that time shall be deemed to
     be the initial bona fide offering thereof.
 
          (3) To remove from registration by means of a post-effective amendment
     any of the securities being registered which remain unsold at the
     termination of the offering.
 
   
          (4) The undersigned registrant hereby undertakes as follows: that
     prior to any public reoffering of the securities registered hereunder
     through use of a prospectus which is a part of this registration statement,
     by any person or party who is deemed to be an underwriter within the
     meaning of Rule 145(c), the issuer undertakes that such reoffering
     prospectus will contain the information called for by the applicable
     registration form with respect to reofferings by persons who may be deemed
     underwriters, in addition to the information called for by the other items
     of the applicable form.
    
 
   
          (5) The registrant undertakes that every prospectus: (i) that is filed
     pursuant to paragraph (1) immediately preceding, or (ii) that purports to
     meet the requirements of Section 10(a)(3) of the Act and is used in
     connection with an offering of securities subject to Rule 415, will be
     filed as a part of an amendment to the registration statement and will not
     be used until such amendment is effective, and that, for purposes of
     determining any liability under the Securities Act of 1933, each such
     post-effective amendment shall be deemed to be a new registration statement
     relating to the securities offered therein, and the offering of such
     securities at that time shall be deemed to be the initial bona fide
     offering thereof.
    
 
     The undersigned Registrant hereby further undertakes that, for the purposes
of determining any liability under the Securities Act of 1933, each filing of
the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange of 1934 that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the
 
                                      II-3
<PAGE>   28
 
securities offered herein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to officers, directors and controlling persons of the
Registrant pursuant to the provisions described under Item 15 of this
registration statement, or otherwise, the Registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in such Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a trustee,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such trustee, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is public policy as expressed in such Act and will be
governed by the final adjudication of such issue.
 
   
     With respect to the Indentures referred to in Exhibits 4.1, 4.2, 4.3 and
4.4 of this Registration Statement, the Registrant hereby undertakes to file an
application for the purpose of determining the eligibility of the trustee to act
under subsection (a) of section 310 of the Trust Indenture Act (the "TIA") in
accordance with the rules and regulations prescribed by the Securities and
Exchange Commission under section 305(b)(2) of the TIA.
