                                  ABOUT SWIFT

     Swift Energy Company engages in the development, exploration, acquisition
and operation of oil and gas properties, with a primary focus on U.S. onshore
gas reserves in Texas and Louisiana. As of December 31, 1998, we had interests
in over 1,750 oil and gas wells located in eight states. We operated 836 of
these wells, representing 91% of our proved reserves. At year-end 1998, we had
estimated proved reserves of 436.1 Bcfe, 81% of which was gas. We focus
primarily on drilling and production in four major fields, with 93% of our 1998
year-end proved reserves and 88% of our 1998 production concentrated in these
four fields:

<S>            <C>                  <C>                    <C>
AWP Olmos      South Texas                  51%               40%
Brookeland     East Texas                   18%                9%
Giddings       South-Central Texas          12%               18%
Masters Creek  Western Louisiana            12%               21%
</TABLE>

     The AWP Olmos Field is characterized by long-lived reserves, while the
other core fields are characterized by shorter-lived reserves with high initial
rates of production. We have extensive experience in these geological trends,
having operated in the AWP Olmos Field since 1988 and the Giddings Field since
1992. Outside our core fields, we are currently pursuing opportunities in the
Gulf Coast Basin and onshore New Zealand.

     In the third quarter of 1998, we purchased interests in the Brookeland and
Masters Creek Fields from Sonat Exploration Company for approximately $85.6
million in cash. The acquisition included approximately 91.1 Bcfe of proved
reserves, a 20% interest in two gas processing plants and interests in
approximately 444,000 net acres. At year-end 1998, the proved reserves of these
fields were estimated to be 130.5 Bcfe, of which approximately 58% was gas and
59% was proved developed. Primarily as a result of the acquisition, our 1998
production increased 54% over 1997 production and the percentage of oil in our
production mix increased from 16% in the first half of 1998 to 37% in the first
half of 1999. We expect to use our operating expertise from similar geological
trends to continue to successfully develop and exploit these fields.

     Over the last several years, our growth in reserves, production and cash
flow has resulted primarily from our increased acreage position, producing
property acquisitions and drilling activities in our core fields. Over the
five-year period ended December 31, 1998:

         - our estimated proved reserves grew from 90.1 Bcfe to 436.1 Bcfe;

         - we replaced 449% of our production at an average cost of $0.88 per
           Mcfe; and

         - our net cash provided by operating activities grew at a compounded
           annual growth rate of 50%.

     From 1997 to 1998, revenues grew from $74.7 million to $82.5 million, and
EBITDA increased from $62.4 million to $65.5 million. Revenues increased from
$32.8 million in the first six months of 1998 to $45.4 million in the same
period of 1999 and EBITDA increased from $26.1 million to $34.6 million.

                                       S-3
<PAGE>   4

These net increases in revenue and EBITDA are primarily due to production
increases resulting from our successful development and exploration program
combined with the Sonat acquisition, which offset declines in gas prices.

     In response to lower oil and gas prices in 1998, we reduced our budgeted
capital expenditures from $183.8 million in 1998 to $54.2 million in 1999. We
have targeted $36.0 million of this 1999 amount for drilling, of which $31.3
million is for development drilling and $4.7 million is for exploratory
drilling. The remaining $18.2 million is for leasehold, seismic and geological
costs of prospects.

     Our principal executive offices are located at 16825 Northchase Drive,
Suite 400, Houston, Texas 77060, and our telephone number is (281) 874-2700.

                               BUSINESS STRATEGY

     Our strategy is to increase our reserves and production through both
drilling and acquisitions, shifting the balance between the two activities in
response to market conditions. In addition, we seek to enhance the results of
our drilling and production efforts through the implementation of advanced
technologies. The elements of our strategy may be further described as follows:

          Development and Exploration Drilling Activities. Our development
     strategy is to maximize the value and productivity of our existing
     properties through carefully targeted drilling and advanced recovery
     methods. We pursue a "controlled" risk approach to exploratory drilling,
     focusing on regions in the U.S. in which we have experience with similar
     geological or production characteristics and which are in close proximity
     to known producing horizons.

          Strategic Acquisitions. We continually review acquisition
     opportunities, using a disciplined, market-driven approach to acquire
     properties which complement our drilling program. We seek to acquire
     properties with significant proved producing reserves and the potential to
     increase reserves and production through additional development and
     exploration efforts.

          Use of Advanced Technologies. We have increasingly used advanced
     technologies to enhance the results of our drilling and production efforts,
     including 2-D and 3-D seismic analysis, amplitude versus offset studies,
     horizontal well drilling technology, innovative fracturing methods and
     coiled tubing technology. In addition, we utilize computer telemetry to
     monitor well performance. As a result of these technologies, we have
     enhanced our production yields while controlling our production costs per
     Mcfe.

                  NOTES TO SUMMARY CONSOLIDATED FINANCIAL DATA

(a)  In the third quarter of 1998, we took a non-cash write-down of oil and gas
     properties. Lower prices for both oil and gas at September 30, 1998,
     necessitated a pre-tax domestic full-cost ceiling write-down of $77.2
     million, or $50.9 million after-tax. Also in the third quarter, we
     re-evaluated the timing of the recovery of our capitalized unproved
     properties costs in Russia due to economic and political uncertainty and
     impaired our total investment of $10.8 million. In addition, the
     international economic uncertainty and currency concerns in Venezuela,
     combined with the price volatility and severe tightening of international
     credit markets, also caused us to impair our capitalized unproved
     properties costs in Venezuela of $2.8 million. The re-evaluation of the
     unproved properties costs in these two countries resulted in a separate
     non-cash pre-tax charge to earnings of $13.6 million, or $9.0 million
     after-tax. The combination of the non-cash full-cost domestic ceiling
     write-down and the non-cash foreign impairment charges resulted in a
     combined non-cash charge to earnings of $90.8 million pre-tax, or $59.9
     million after-tax.

(b)  Amounts have been retroactively restated in all periods presented to
     reflect two 10% stock dividends, one in September 1994, the other in
     October 1997.

(c)  On a pro forma basis, assuming the 1994 change in accounting principle is
     applied retroactively, basic and diluted earnings per share would have been
     $0.51 for 1994.

(d)  EBITDA represents income before interest expense, income tax, and
     depreciation, depletion and amortization (including the 1998 write-down of
     oil and gas properties). We have reported EBITDA because we believe EBITDA
     is a measure commonly reported and widely used by investors as an indicator
     of a company's operating performance and ability to incur and service debt.
     We believe EBITDA assists such investors in comparing a company's
     performance on a consistent basis without regard to depreciation, depletion
     and amortization, which can vary significantly depending upon accounting
     methods or nonoperating factors such as historical cost. EBITDA is not a
     calculation based on GAAP and should not be considered an alternative to
     net income in measuring our performance or used as an exclusive measure of
     cash flow because it does not consider the impact of working capital
     growth, capital expenditures, debt principal reductions and other sources
     and uses of cash which are disclosed in our Consolidated Statements of Cash
     Flows. Investors should carefully consider the specific items included in
     our computation of EBITDA. While EBITDA has been disclosed herein to permit
     a more complete comparative analysis of our operating performance and debt
     servicing ability relative to other companies, investors should be
     cautioned that EBITDA as reported by us may not be comparable in all
     instances to EBITDA as reported by other companies. EBITDA amounts may not
     be fully available for management's discretionary use, due to certain
     requirements to conserve funds for capital expenditures, debt service and
     other commitments. The definition of EBITDA stated herein differs from the
     definition of EBITDA applicable to the covenants for the notes, in that the
     notes definition makes certain exclusions to net income, some of which
     would reduce EBITDA. SEE, "DESCRIPTION OF THE NOTES -- CERTAIN
     DEFINITIONS -- CONSOLIDATED NET INCOME" AND "-- EBITDA."

(e)  For purposes of calculating the ratio of earnings to fixed charges, fixed
     charges include interest expense, capitalized interest, amortization of
     debt issuance costs and that portion of non-capitalized rental expense
     deemed to be the equivalent of interest. Earnings represents income before
     income taxes from continuing operations before fixed charges. Due to the
     $90.8 million non-cash charge incurred in 1998 caused by a write-down in
     the carrying value of gas and oil properties, 1998 earnings were
     insufficient by $76.9 million to cover fixed charges in 1998. If the $90.8
     million non-cash charge is excluded, the ratio of earnings to fixed charges
     would have been 2.1x for 1998.

(f)  Cash interest is defined as the total amount of interest paid on our
     obligations, prior to any allowed capitalized amount.

                 NOTES TO SUMMARY RESERVES AND PRODUCTION DATA

(a)  Quantity estimates, their PV-10 Value and the standardized measure are
     affected by the change in crude oil and gas prices at the end of each year.
     While our total proved reserves quantities on an MMcfe basis at year-end
     1998 increased by 21% over reserves quantities at the prior year-end, the
     PV-10 Value decreased 3% and the standardized measure of those reserves
     decreased 1%, from the PV-10 Value and standardized measure at year-end
     1997. This decrease was almost entirely due to lower year-end 1998 prices.

(b)  Calculated for a three-year period ending with the year presented by
     dividing total acquisition, exploration and development costs, excluding
     future development costs, during such period by net reserves added during
     the period, including any revisions of those reserves.

(c)  Calculated for a three-year period ending with the year presented by
     dividing the increase in net reserves, including any revisions of those
     reserves, by the production quantities for such period.

(d)  Gas production for the six months ended June 30, 1999 and for the years
     ended 1998, 1997, 1996, 1995 and 1994 includes 384, 866, 1,015, 1,156,
     1,211 and 1,358 MMcf delivered under the volumetric production payment
     agreement pursuant to which we are obligated to deliver certain monthly
     quantities of gas to a third party through October 2000. Future volumes
     associated with the volumetric production payment are not included in our
     estimates of future net reserves.

                                  RISK FACTORS

     An investment in our notes involves significant risks. You should carefully
consider the following risk factors before you decide to buy the notes. You
should also carefully read and consider all of the information we have included,
or incorporated by reference, in this prospectus supplement and the accompanying
prospectus before you decide to buy the notes.

LOW OIL AND GAS PRICES HURT OUR FINANCIAL RESULTS AND CONDITION.

     Prices for oil and gas have become increasingly volatile and declined
significantly during the second half of 1998 and early 1999. Gas prices affect
us more than oil prices, as gas production was 72% of our 1998 production and
63% of our production in the first half of 1999. In 1998, gas prices we received
were 22% lower than 1997 prices, and oil prices were 33% lower. Primarily
because of lower prices, we recorded a ceiling test write down causing us to
incur a net loss for 1998. Prices remaining at lower levels or decreasing
further would negatively affect us in several ways:

     - our cash flows would be reduced, decreasing funds available for capital
       expenditures employed to replace reserves or increase production;

     - certain reserves would no longer be economic to produce, leading to both
       lower proved reserves and cash flow;

     - our lenders could reduce the borrowing base under our credit facility
       because of lower oil and gas reserve values, reducing our liquidity and
       possibly requiring mandatory loan repayments;

     - access to other sources of capital, such as equity or long-term debt
       markets, could be severely limited or unavailable in a low price
       environment; and

     - we could be required to take another ceiling test write down of the
       carrying values of our properties.

Consequently, our revenues and profitability would suffer. Most of the factors
which affect price volatility are beyond our control, such as demand, worldwide
economic conditions, weather conditions, supply levels, import prices, political
conditions in major oil producing regions, especially the Middle East, and
actions taken by OPEC.

OUR SUBSTANTIAL DEBT REDUCES OUR FINANCIAL FLEXIBILITY AND OUR DEBT LEVELS MAY
GROW.

     After giving effect to this offering and the concurrent offering of common
stock, on a pro forma basis at June 30, 1999, our long-term debt would equal
approximately 61% of our capitalization. A high level of debt:

     - requires us to dedicate a significant portion of our cash flow to the
       payment of interest;

     - subjects us to a higher financial risk in an economic downturn due to our
       substantial debt service costs;

     - limits our ability to obtain financing or raise equity capital in the
       future; and

     - may place us at a competitive disadvantage to the extent that we are more
       highly leveraged than some of our peers.

     Subject to restrictions in our credit facility and the indenture for the
notes, we may borrow up to approximately $140.0 million for capital
expenditures. If we add additional debt to our current debt levels, the risks
discussed above would be accentuated.

IF WE CANNOT REPLACE OUR RESERVES, OUR REVENUES AND FINANCIAL CONDITION WILL
SUFFER.

     Unless we successfully replace our reserves, our production will decline,
resulting in lower revenues and cash flow. This is accentuated by the fact that
approximately 42% of our reserves at December 31, 1998 are in the Austin Chalk
trend where wells typically have very steep rates of decline. Lower prices
                                      S-11
<PAGE>   12

decrease our cash flow which can be dedicated to finding or purchasing new
producing reserves, and make borrowing and equity sales more difficult. Thus, we
need to spend significant amounts of capital to discover or purchase new
reserves. In response to lower oil and gas prices, our capital expenditures in
1999 are budgeted at $54.2 million, compared to $183.8 million in 1998 and
$132.0 million in 1997. It is likely that capital expenditures in 2000 will be
closer to the levels budgeted for 1999, rather than the levels spent in 1998. At
this level of capital expenditures, it is more difficult to replace our
reserves. Furthermore, for the reasons discussed below, even if capital is spent
on drilling or to make acquisitions, such efforts have a high risk of being
unsuccessful.

WE MAY INCUR ADDITIONAL WRITE DOWNS OF THE CARRYING VALUES OF OUR PROPERTIES.

     SEC accounting rules require that on a quarterly basis we review the
carrying value of our oil and gas properties for possible write down or
impairment. Under these rules, capitalized costs of proved reserves may not
exceed the present value of estimated future net revenues from those proved
reserves, determined using a 10% per year discount and unescalated prices in
effect as of the end of each fiscal quarter. Primarily because of weak prices,
in the third quarter of 1998 we recorded a $77.2 million pre-tax ceiling
limitation write down for our domestic properties. Similarly, pricing and
currency factors, together with economic and political uncertainty in Russia and
Venezuela, led to a $13.6 million pre-tax impairment of our foreign investments
in those regions. This resulted in a combined non-cash charge of $90.8 million
before taxes in 1998.

     We may be required to write down the carrying value of our oil and gas
properties in the future if oil and gas prices are depressed for even a short
period, are unusually volatile or if we have substantial downward revisions to
our proved reserves quantities. Any such ceiling test write down would result in
a charge to earnings and a reduction of stockholders' equity, but would not
impact our cash flow from operating activities. Once incurred, these write downs
are not reversible at a later date.

     Given that full cost accounting rules are applied on a country-by-country
basis, we are currently exposed to the risk of a possible write down or
impairment of our properties in New Zealand. At June 30, 1999, our investments
in New Zealand totaled $5.4 million. To date, our drilling efforts there have
not been successful in establishing proved reserves. We have commenced drilling
an exploratory well under our New Zealand permit which we expect to conclude
during the second half of 1999. Swift's portion of the currently budgeted
drilling costs of this well are approximately $4.3 million. This exploratory
well is speculative. If this well does not discover economic reserves, in the
second half of 1999 we may be required to write down a large portion of our
drilling and capitalized costs. SEE, "BUSINESS AND PROPERTIES -- FOREIGN
ACTIVITIES."

DRILLING WELLS IS SPECULATIVE AND CAPITAL INTENSIVE.

     Developing and exploring for oil and gas properties requires significant
capital expenditures and involves a high degree of financial risk. The budgeted
costs of drilling, completing and operating wells are often exceeded and can
increase significantly when drilling costs rise and supply tightens. Drilling
may be unsuccessful for many reasons, including title problems, weather, cost
overruns, equipment shortages and mechanical difficulties. Moreover, the
successful drilling of an oil or gas well does not ensure a profit on
investment. Exploratory wells bear a much greater risk of loss than development
wells. A variety of factors, both geological and market-related, can cause a
well to become uneconomical or only marginally economic. In addition to their
cost, unsuccessful wells can hurt our efforts to replace reserves.

RESERVES ON PROPERTIES WE BUY MAY NOT MEET OUR EXPECTATIONS AND COULD CHANGE THE
NATURE OF OUR BUSINESS.

     Property acquisition decisions are based on various assumptions and
subjective judgments that are speculative. Although available geological and
geophysical information can provide information about the potential of a
property, it is impossible to predict accurately a property's production and
profitability. Furthermore, future acquisitions may change the nature of our
operations and business. For example, an acquisition of producing properties
containing primarily oil reserves could change our current emphasis on gas
reserves.

                                      S-12
<PAGE>   13

     In addition, we may have difficulty integrating future acquisitions into
our operations, and they may not achieve our desired profitability objectives.
Likewise, as is customary in the industry, we generally acquire oil and gas
acreage without any warranty of title except through the transferor. In many
instances, title opinions are not obtained if, in our judgment, it would be
uneconomical or impractical to do so. Losses may result from title defects or
from defects in the assignment of leasehold rights. While our current operations
are primarily in Texas and Louisiana, we may pursue acquisitions or properties
located in other geographic areas, which would decrease our geographical
concentration, but would also be in areas in which we have no or limited
experience.

ESTIMATES OF OUR PROVED RESERVES ARE UNCERTAIN AND OUR REVENUES FROM PRODUCTION
MAY VARY SIGNIFICANTLY FROM ESTIMATED AMOUNTS.

     The quantities and values of our proved reserves included in this
prospectus supplement are only estimates and subject to numerous uncertainties.
Estimates by other engineers might differ materially. The accuracy of any
reserve estimate is a function of the quality of available data and of
engineering and geological interpretation. These estimates depend on assumptions
regarding quantities and production rates of recoverable oil and gas reserves,
future prices for oil and gas, timing and amounts of development expenditures
and operating expenses, all of which will vary from those assumed in our
estimates. These variances may be significant.

     Any significant variance from the assumptions used could result in the
actual amounts of oil and gas ultimately recovered and future net cash flows
being materially different from the estimates in our reserve reports. In
addition, results of drilling, testing, production and changes in prices after
the date of the estimate may result in substantial downward revisions. These
estimates may not accurately predict the present value of net cash flows from
oil and gas reserves.

     At December 31, 1998, approximately 45% of our estimated proved reserves
were undeveloped. Recovery of undeveloped reserves generally requires
significant capital expenditures and successful drilling operations. The reserve
data assumes that we can and will make these expenditures and conduct these
operations successfully, which may not occur.

THE NOTES WILL BE SUBORDINATED TO ALL OF OUR EXISTING AND FUTURE SENIOR DEBT.

     The notes will be subordinated in right of payment to all of our present
and future senior debt, the senior debt of any subsidiaries that guarantee the
notes and all debt and trade payables of other subsidiaries. As of June 30,
1999, after giving pro forma effect to this offering, the concurrent offering of
the common stock and the intended use of the proceeds, we would have no senior
debt, although in the future we may borrow up to approximately $140.0 million
under our credit facility, all of which would be senior debt. As a result, in
the event of bankruptcy or reorganization, or upon acceleration of the notes due
to an event of default, we are required to repay our senior debt in full before
we pay you. Accordingly, there may not be sufficient assets remaining to pay
amounts due to you on any or all of the notes. Similarly, if there is a default
on our senior debt, it is likely that no payments may be made on the notes. We
will be limited, but not prohibited, by the indenture governing the notes from
incurring additional debt that is senior to the notes.

WE DO NOT INSURE AGAINST ALL POTENTIAL LOSSES AND COULD BE SERIOUSLY HARMED BY
UNEXPECTED LIABILITIES.

     Exploration for and production of oil and gas can be hazardous, involving
natural disasters and other unforeseen occurrences such as blowouts, cratering,
fires and loss of well control, which can damage or destroy wells or production
facilities, injure or kill people, and damage property and the environment.
Because third party drilling contractors are used to drill our wells, we may not
realize the full benefit of workman's compensation laws in dealing with their
employees. We maintain insurance against many potential losses and liabilities
arising from our operations in accordance with customary industry practices and
in amounts that we believe to be prudent. However, our insurance does not
protect us against all operational risks.

                                      S-13
<PAGE>   14

OUR HEDGING ACTIVITIES MAY RESULT IN LOSSES.

     From time to time we enter into hedging activities in an effort to mitigate
the potential impact of declines in oil and gas prices. These activities consist
of buying protection price floors for some of our oil and gas production. The
cost of these floors may be lost if prices rise, and thus these arrangements
reduce the benefit of increases in the price of oil or gas while providing only
partial protection against declines in prices. FOR A MORE DETAILED DESCRIPTION
OF OUR HEDGING ACTIVITIES, SEE "BUSINESS AND PROPERTIES -- PRICE RISK
MANAGEMENT," AND NOTE 1 TO THE CONSOLIDATED FINANCIAL STATEMENTS.

GOVERNMENTAL REGULATIONS ARE COSTLY AND COMPLEX, ESPECIALLY REGULATIONS RELATING
TO ENVIRONMENTAL PROTECTION.

     Our exploration, production and marketing operations are regulated
extensively at the federal, state and local levels, which regulations affect the
costs, manner and feasibility of our operations. As an owner and operator of oil
and gas properties, we are subject to federal, state and local regulation of
discharge of materials into, and protection of, the environment. We have made
and will continue to make significant expenditures in our efforts to comply with
the requirements of these environmental regulations, which may impose liability
on us for the cost of pollution clean-up resulting from operations, subject us
to liability for pollution damages and require suspension or cessation of
operations in affected areas. Changes in or additions to regulations regarding
the protection of the environment could increase our compliance costs and might
hurt our business.

     We are subject to state and local regulations that impose permitting,
reclamation, land use, conservation and other restrictions on our ability to
drill and produce. These laws and regulations can require well and facility
sites to be closed and reclaimed. We frequently buy and sell interests in
properties that have been operated in the past, and as a result of these
transactions we may retain or assume clean-up or reclamation obligations for our
own operations or those of third parties.

RELIANCE ON SENIOR OFFICERS AND OTHER KEY EMPLOYEES.

     We rely on key employees and their expertise. If we were to lose several of
our key technical employees or executive officers, our operations could suffer
during their successors' transition periods. A. Earl Swift, our chief executive
officer and founder, has indicated a desire to retire during the fourth quarter
of 1999, which could adversely affect our day-to-day operations, although he
intends to remain as chairman of the board of directors. The board of directors
has commenced its search for Mr. Swift's replacement as chief executive officer.

WE ARE EXPOSED TO FINANCIAL AND OTHER LIABILITIES AS THE GENERAL PARTNER IN
NUMEROUS LIMITED PARTNERSHIPS.

     We currently serve as the managing general partner of 80 limited
partnerships. We are contingently liable for our obligations as a general
partner, including responsibility for day-to-day operations and any liabilities
that cannot be repaid from partnership assets or insurance proceeds. At June 30,
1999, the partnerships' only liabilities were to Swift in the amount of
approximately $6.8 million. In the future, we may be exposed to litigation in
connection with partnership activities, or find it necessary to advance funds on
behalf of certain partnerships to protect the value of their oil and gas
properties. FOR MORE DETAILED DESCRIPTION, SEE "BUSINESS AND
PROPERTIES -- PARTNERSHIPS."

WE MAY HAVE DIFFICULTY COMPETING FOR OIL AND GAS PROPERTIES OR SUPPLIES.

     We operate in a highly competitive environment, competing with major
integrated and independent energy companies for desirable oil and gas
properties, as well as for the equipment, labor and materials required to
develop and operate such properties. Many of these competitors have financial
and technological resources substantially greater than ours. The market for oil
and gas properties is highly competitive and we may lack technological
information or expertise available to other bidders. We may incur higher costs
or be unable to acquire and develop desirable properties at costs we consider
reasonable because of this competition.
                                      S-14
<PAGE>   15

WE ARE ENGAGED IN FOREIGN ACTIVITIES THAT EXPOSE US TO LOSSES FROM POLITICAL AND
ECONOMIC CONDITIONS ABROAD.

     We are engaged in development and exploration activities in New Zealand,
have an existing net profits agreement in Russia and are pursuing pipeline
ventures in Venezuela. These foreign activities subject us to risks of foreign
currency fluctuations and controls, changes in foreign laws or their enforcement
and political and economic instability. Due to prevailing economic conditions in
the third quarter of 1998 in both Russia and Venezuela, we impaired our
capitalized unproved properties costs in both countries, resulting in a pre-tax
charge to earnings of $13.6 million. SEE, "BUSINESS AND PROPERTIES -- FOREIGN
ACTIVITIES."

FRAUDULENT CONVEYANCE CONSIDERATIONS COULD AVOID GUARANTEES FOR THE NOTES.

     In the future, some of our subsidiaries might guarantee our obligations
under the notes on an unsecured senior subordinated basis. Under fraudulent
conveyance laws, a court might subordinate or avoid any guarantees of the notes
by our subsidiaries in favor of a subsidiary's other debts or liabilities. To
the extent a subsidiary's guarantee of the notes is avoided as a result of
fraudulent conveyance laws or held unenforceable for any other reason, you would
receive no payments under that subsidiary's guarantee and would be creditors
solely of us and any subsidiaries whose guarantees were not avoided.

IF WE EXPERIENCE A CHANGE OF CONTROL, WE MAY BE UNABLE TO REPURCHASE THE NOTES
AS REQUIRED UNDER THE INDENTURE.

     In the event of a change of control, you will have the right to require us,
subject to various conditions, to repurchase the notes. We may not have
sufficient financial resources to pay the repurchase price for the notes, or may
be prohibited from doing so under our credit facility or other debt agreements.
In addition, before we can purchase any notes, we may be required to:

     - repay our bank debt or other debt that ranks senior to the notes; or

     - obtain a consent from lenders of senior debt to permit purchase of the
       notes.

     If a change of control occurs and we are prohibited from repurchasing the
notes, our failure to do so would cause us to default under the indenture, which
in turn is likely to be a default under our credit facility and our outstanding
convertible notes due 2006 and any future debt. Any other default under our
credit facility or other debt would also likely prohibit our repurchasing the
notes.

WE AND OUR SUPPLIERS OR PARTNERS MAY NOT BE YEAR 2000 COMPLIANT, WHICH COULD
RESULT IN DISRUPTION OF OUR OPERATIONS.

     Actual effects of the Year 2000 issue are subject to uncertainties. Our
Year 2000 program may not completely identify every potential problem which may
arise. Our inability to completely solve all potential problems or address all
potentially affected systems could materially hurt our business. Likewise, our
business suppliers and partners may experience unanticipated Year 2000 problems
which could in turn affect our operations. In addition, we have relied on
representations from third parties that our systems and the systems of third
parties with whom we conduct business are Year 2000 compliant. However, because
of the difficulty in anticipating all effects of the Year 2000 issue, these
representations are not guarantees. If there are Year 2000 related failures in
our critical systems or our business suppliers' and partners' critical systems
that create substantial or prolonged disruptions to our business, the adverse
impact on us could materially affect our financial condition or results of
operations. FOR A MORE DETAILED DESCRIPTION OF OUR YEAR 2000 PROGRAM, SEE
"MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS -- YEAR 2000."

THE NOTES HAVE NO EXISTING MARKET AND A MARKET MAY NOT DEVELOP.

     There is no existing market for the notes, and we are not applying to list
the notes on any securities exchange. Therefore, no liquid market may exist for
the notes at any time, which may depress the prices at which you will be able to
sell your notes.

WE MAY NOT FINALIZE OUR PENDING LITIGATION SETTLEMENT.

     The tentative agreement we have recently reached with the Lower Colorado
River Authority to settle our pending litigation, involving claims against us
alleged not to exceed $10.0 million exclusive of punitive damages, may not be
consummated and we may have to continue pursuing the matter in court. SEE,
"BUSINESS AND PROPERTIES -- LITIGATION."

                                USE OF PROCEEDS

     We estimate that the net proceeds from the sale of the notes will be
approximately $120.3 million after deducting underwriting discounts and
expenses. Concurrently with this notes offering, we are offering 4,000,000
shares of common stock with estimated net proceeds of $36.7 million, or $42.2
million if the underwriters fully exercise their over-allotment option. The two
offerings are not conditioned upon each other.

     We intend to use the net proceeds of the two offerings, which are estimated
to be $157.0 million in the aggregate, to repay the outstanding debt under our
credit facility. We intend to use any excess net proceeds together with funds
then made available under our credit facility for capital expenditures,
acquisitions and general corporate purposes. As of June 30, 1999, the credit
facility had an outstanding balance of $140.0 million, of which $85.6 million
was used for the Sonat acquisition and the remainder was used for working
capital purposes. The weighted average interest rate was 6.64% at June 30, 1999.
Our credit facility matures August 18, 2002. After we apply the net proceeds of
both offerings to reduce our bank debt, we will have no outstanding balance
under the credit facility, and a borrowing base of $140.0 million. FOR A MORE
DETAILED DESCRIPTION OF OUR CREDIT FACILITY, SEE, "DESCRIPTION OF EXISTING
INDEBTEDNESS."

                                 CAPITALIZATION

     The following table sets forth as of June 30, 1999:

     - our historical capitalization;

     - our capitalization as adjusted to show the receipt of the estimated net
proceeds from the sale of:

        - the notes being sold in this offering; and

        - the concurrent notes and common stock offerings;

     but does not reflect:

        - the sale of up to 600,000 shares of common stock to the underwriters
          if they exercise their over-allotment option in the concurrent common
          stock offering;

        - 2,237,877 shares that may be issued pursuant to stock compensation
          plans as of June 30, 1999; or

        - 3,646,847 shares of common stock that may be issued upon conversion of
          our convertible notes due 2006.

     This table should be read in conjunction with "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and the consolidated
financial statements and the related notes contained in this prospectus
supplement.

            NOTES TO SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA

(a)  In the third quarter of 1998, we took a non-cash write-down of oil and gas
     properties. Lower prices for both oil and gas at September 30, 1998,
     necessitated a pre-tax domestic full-cost ceiling write-down of $77.2
     million, or $50.9 million after tax. Also in the third quarter, we
     re-evaluated the timing of the recovery of our capitalized unproved
     properties costs in Russia due to economic and political uncertainty and
     impaired our total investment of $10.8 million. In addition, the
     international economic uncertainty and currency concerns in Venezuela
     combined with the price volatility and severe tightening of international
     credit markets, also caused us to impair our capitalized unproved
     properties costs in Venezuela of $2.8 million. The re-evaluation of the
     unproved properties costs in these two countries resulted in a separate
     non-cash pre-tax charge to earnings of $13.6 million, or $9.0 million after
     tax. The combination of the non-cash full-cost domestic ceiling write-down
     and the non-cash foreign impairment charges resulted in a combined non-cash
     charge to earnings of $90.8 million pre-tax, or $59.9 million after tax.

(b)  Amounts have been retroactively restated in all periods presented to
     reflect two 10% stock dividends, one in September 1994, the other in
     October 1997.

(c)  On a pro forma basis, assuming the 1994 change in accounting principle is
     applied retroactively, basic and diluted earnings per share would have been
     $0.51 for 1994.

(d)  EBITDA represents income before interest expense, income tax, and
     depreciation, depletion and amortization (including the 1998 write-down of
     oil and gas properties). We have reported EBITDA because we believe EBITDA
     is a measure commonly reported and widely used by investors as an indicator
     of a company's operating performance and ability to incur and service debt.
     We believe EBITDA assists such investors in comparing a company's
     performance on a consistent basis without regard to depreciation, depletion
     and amortization, which can vary significantly depending upon accounting
     methods or nonoperating factors such as historical cost. EBITDA is not a
     calculation based on GAAP and should not be considered an alternative to
     net income in measuring our performance or used as an exclusive measure of
     cash flow because it does not consider the impact of working capital
     growth, capital expenditures, debt principal reductions and other sources
     and uses of cash which are disclosed in our Consolidated Statements of Cash
     Flows. Investors should carefully consider the specific items included in
     our computation of EBITDA. While EBITDA has been disclosed herein to permit
     a more complete comparative analysis of our operating performance and debt
     servicing ability relative to other companies, investors should be
     cautioned that EBITDA as reported by us may not be comparable in all
     instances to EBITDA, as reported by other companies. EBITDA amounts may not
     be fully available for management's discretionary use, due to certain
     requirements to conserve funds for capital expenditures, debt service and
     other commitments. The definition of EBITDA stated herein differs from the
     definition of EBITDA applicable to the covenants for the notes, in that the
     notes definition makes certain exclusions to net income, some of which
     would reduce EBITDA. SEE, "DESCRIPTION OF THE NOTES -- CERTAIN
     DEFINITIONS -- CONSOLIDATED NET INCOME" AND "-- EBITDA."

(e)  For purposes of calculating the ratio of earnings to fixed charges, fixed
     charges include interest expense, capitalized interest, amortization of
     debt issuance costs and that portion of non-capitalized rental expense
     deemed to be the equivalent of interest. Earnings represents income before
     income taxes from continuing operations before fixed charges. Due to the
     $90.8 million non-cash charge incurred in 1998 caused by a write-down in
     the carrying value of gas and oil properties, 1998 earnings were
     insufficient by $76.9 million to cover fixed charges in 1998. If the $90.8
     million non-cash charge is excluded, the ratio of earnings to fixed charges
     would have been 2.1x for 1998.

(f)  Cash interest is defined as the total amount of interest paid on our
     obligations, prior to any allowed capitalized amount.

                      CONDITION AND RESULTS OF OPERATIONS

     You should read the following discussion and analysis in conjunction with
our financial information and our consolidated financial statements and notes

GENERAL

     Over the last several years, we have emphasized adding reserves through
drilling activity. We also add reserves through strategic purchases of producing
properties when oil and gas prices are lower and other market conditions are
appropriate, as we did in the third quarter of 1998 with the purchase of the
Brookeland and Masters Creek Fields from Sonat Exploration Company. Since 1996,
we have used this flexible strategy of employing both drilling and acquisitions
to add more reserves than we depleted through production. Our revenues are
primarily from oil and gas sales attributable to properties in which we own a
direct or indirect interest.

     Proved Oil and Gas Reserves. At year-end 1998, our total proved reserves
were 436.1 Bcfe with a PV-10 Value of $340.8 million. In 1998, we increased our
proved gas reserves by 38.1 Bcf, or 12%, and our proved oil reserves by 6.1
MMBbl or 78%, for a total of 74.7 Bcfe representing a 21% increase. From 1996 to
1997, we increased our proved gas reserves by 88.5 Bcf, or 39%, and our proved
oil reserves by 2.4 MMBbl, or 43%, for a total of 102.8 Bcfe representing a 40%
increase. Through drilling, we added 73.9 Bcfe of proved reserves in 1998, 120.2
Bcfe in 1997 and 118.2 Bcfe in 1996. Through acquisitions we added 97.6 Bcfe of
proved reserves in 1998, 33.8 Bcfe in 1997 and 3.3 Bcfe in 1996. A substantial
portion of these reserves were proved undeveloped. At year-end 1998, 45% of our
total proved reserves were proved undeveloped, compared with 40% at year-end
1997 and 39% at year-end 1996.

     While our total proved reserves quantities at year-end 1998 increased by
21% over those at year-end 1997, the PV-10 Value of those reserves decreased 3%
over the same period, almost entirely due to pricing declines during 1998. We
added reserves from 1997 to 1998 through our drilling activity, primarily in the
AWP Olmos and Giddings Fields, and through purchases of minerals in place,
primarily in the Brookeland and Masters Creek Fields. These additions to our
reserves were offset by revisions of previous estimates, the 20% decrease in
year-end 1998 gas prices, and the 29% decrease in year-end 1998 oil prices. Gas
prices were $2.23 per Mcf at year-end 1998 compared to $2.78 per Mcf at year-end
1997. Oil prices were $11.23 per Bbl at year-end 1998 compared to $15.76 a year
earlier. If the 1998 year-end PV-10 Value and 1998 year-end standardized measure
had been calculated using year-end 1997 prices, there would have been an
increase in the PV-10 Value and standardized measure from year-end 1997 to
year-end 1998 comparable to the 21% increase in the total proved reserves
quantities during that same period. FOR A MORE DETAILED DESCRIPTION, SEE

RESULTS OF OPERATIONS -- SIX MONTHS ENDED JUNE 30, 1999 AND JUNE 30, 1998

     Revenues. Our revenues increased 38% during the first six months of 1999 as
compared to the same period in 1998. This increase was caused by the growth in
our oil and gas sales, which resulted from the increase in production volumes
and which was offset by lower gas prices.

     Oil and Gas Sales. Our oil and gas sales increased 42% to $44.7 million in
the first six months of 1999, compared to $31.5 million for the comparable
period in 1998. Our gas production increased 16% and oil production increased
256% primarily due to production from the Brookeland and Masters Creek Fields,
which were acquired in the third quarter of 1998. Our net sales volume in the
first six months of 1999 increased by 55%, or 7.8 Bcfe, over volumes in the same
period in 1998. A 14% decrease in gas prices between the two periods
significantly offset the increase in volume and 9% increase in oil prices.

     Our $13.2 million increase in oil and gas sales during the first six months
of 1999 resulted from:

     - Volume increases which added $16.0 million of sales, with $4.2 million of
       the increase coming from the 1.9 Bcf increase in gas sales volumes and
       $11.8 million of the increase coming from the 987,000 Bbl increase in oil
       sales volumes; and

     - Price variances, which had a $2.8 million unfavorable impact on sales due
       to the decrease in average gas prices received of $4.2 million offset by
       an increase of $1.4 million in average oil prices received.

     The following table provides additional information regarding the changes
in the sources of our oil and gas sales and volumes for the first six month
periods of 1999 and 1998.

</TABLE>

     Revenues from oil and gas sales comprised 98% of our total revenues for the
first six months of 1999 as compared to 96% for the first half of 1998. Our
acquisition of interests in the Masters Creek and Brookeland Fields, which have
a higher percentage of production from oil, has decreased the predominance of
gas in our production mix from 84% in the first six months of 1998 to 63% in the
first six months of 1999. Even though we scaled back our 1999 capital
expenditures budget, we expect oil and gas sales volumes to increase in 1999
when compared to 1998, primarily due to the full year of production from the
Brookeland and Masters Creek Fields. However, due to the decrease in our 1999
capital expenditures budget, and the resulting curtailment of new drilling in
the Giddings Field, the natural production decline in this field was not offset
by newly developed production.

     The following table provides additional information regarding our oil and
gas sales:

     Costs and Expenses. Our general and administrative expenses for the first
six months of 1999 increased approximately $0.4 million, when compared to the
same period in 1998. However, our general and administrative expenses per Mcfe
produced decreased by 21% from $0.13 per Mcfe for the first six months of 1998
to $0.10 per Mcfe for the comparable period in 1999. Supervision fees netted
from general and administrative expenses for the first six months of 1999 were
$1.5 million and for the same period of 1998 were $1.4 million.

     Depreciation, depletion and amortization of our assets, or DD&A, increased
52% or approximately $7.2 million for the first six months of 1999. This was
primarily due to additions to our reserves and associated costs and to the
related 55% increase in production volumes from the added reserves primarily
resulting from the Sonat acquisition as compared to the same period in 1998. Our
DD&A rate per Mcfe of production has decreased from $0.98 per Mcfe in the first
six months of 1998 to $0.96 per Mcfe in the same 1999 period.

     Our production costs per Mcfe increased to $0.39 per Mcfe in the first half
of 1999 from $0.34 per Mcfe in the same 1998 period. In the Brookeland and
Masters Creek Fields, a higher percentage of our
                                      S-22
<PAGE>   23

production is from oil. Production costs for oil typically are higher than those
for gas, resulting in a higher production cost per Mcfe. Primarily due to the
55% increase in our production volumes, oil and gas production costs increased
by 75%, or approximately $3.7 million, in the first six months of 1999 when
compared to the first six months of 1998. Supervision fees netted from
production costs for the first six months of 1999 were $1.5 million and for the
first six months of 1998 were $1.4 million.

     Interest expense on our convertible notes due 2006, including amortization
of debt issuance costs, was the same in the first six months of 1999 and in
1998, totaling $3.8 million. Interest expense on our credit facility, including
commitment fees and amortization of debt issuance costs, totaled $4.9 million in
the first six months of 1999, compared to $1.1 million for our credit facilities
in the same 1998 period. Thus, 1999 total interest charges were $8.7 million, of
which $2.0 million was capitalized. In the first six months of 1998, these
charges totaled $4.8 million, of which $1.8 million was capitalized. We
capitalized that portion of interest related to our exploration, partnership and
foreign business development activities. The increase in interest expense in
1999 is attributable to the increase in amounts outstanding under our credit
facility.

     Net Income. Our net income for the first six months of 1999 of $4.4 million
and basic earnings per share, or EPS, of $0.27 were both 27% lower than net
income of $6.1 million and basic EPS of $0.37 for the same period in 1998. This
decrease primarily reflected the effect of lower gas prices, while our costs and
expenses increased 63% in relation to the 55% increase in production volumes
discussed above.

RESULTS OF OPERATIONS -- YEARS ENDED DECEMBER 31, 1998, 1997 AND 1996

     Revenues. Our revenues increased by 10% in 1998 over revenues in 1997, and
increased by 32% in 1997 over 1996 revenues, principally due to increases in oil
and gas sales revenues.

     Oil and Gas Sales. Our oil and gas sales revenues in 1998 increased by 16%,
or $11.1 million, over those revenues for 1997. In 1997, oil and gas sales
revenues increased by 31%, or $16.2 million, over those revenues in 1996. Our
net sales volumes in 1998, including the volumetric production payment
associated with each year's production, increased by 54%, or 13.6 Bcfe, over net
sales volumes in 1997. In 1997, net sales volumes increased by 31%, or 6.0 Bcfe,
over net sales volumes in 1996. Average prices for oil declined from $19.82 per
Bbl in 1996 to $17.59 per Bbl in 1997 and to $11.86 per Bbl in 1998. Average gas
prices increased slightly from $2.57 per Mcf in 1996 to $2.68 per Mcf in 1997,
and then decreased to $2.08 per Mcf in 1998.

     In 1998, our $11.1 million increase in oil and gas sales resulted from:

     - Volume increases that added $38.3 million of sales with $18.4 million of
       the increase coming from the 6.9 Bcf increase in gas sales volumes and
       $19.9 million of the increase coming from the 1.1 MMBbl increase in oil
       sales volumes; and

     - Price variances that had a $27.2 million unfavorable impact on sales,
       $16.9 million of which was attributable to the 22% decrease in average
       gas prices received, and $10.3 million of which was attributable to the
       33% decrease in average oil prices received.

     In 1997, our $16.2 million increase in oil and gas sales resulted from:

     - Volume increases that added $15.5 million of sales, with $14.5 million of
       the increase coming from the 5.7 Bcf increase in gas sales volumes and
       $1.0 million of the increase coming from the 49,000 Bbl increase in oil
       sales volumes; and

     - Price variances that added $0.7 million to sales, with $2.2 million in
       increased sales from the increase in average gas prices received, offset
       by a $1.5 million decrease in sales from the decrease in average oil
       prices received.

     In 1998, the increases in oil and gas sales were primarily the result of
the addition of production from the Brookeland and Masters Creek Fields during
the second half of 1998. The decisions to acquire the Brookeland and Masters
Creek Fields and to defer some drilling were both made in response to market

                                      S-23
<PAGE>   24

conditions. In 1997, the increases in oil and gas sales were primarily the
result of production from our accelerated drilling program, most notably in the
AWP Olmos and Giddings Fields.

     The following table provides additional information regarding the changes
in the sources of our oil and gas sales and volumes from 1997 to 1998.

Masters Creek            $17.5       --     8.2      --
</TABLE>

     Revenues from our oil and gas sales comprised 97% of total revenues for
1998, 92% of total revenues for 1997 and 94% of total revenues for 1996. The
Brookeland and Masters Creek Fields which have a higher percentage of production
from oil, with oil making up approximately 56% of these fields' 1998 production,
have altered our predominate gas production mix.

     Costs and Expenses. Our general and administrative expenses in 1998
increased $0.3 million, or 9%, from the level of such expenses in 1997, while
1997 general and administrative expenses decreased $0.6 million, or 15%, below
1996 levels. The small variances in these costs over the three-year period
reflect our ability to increase our activities and reserves base without
materially increasing related costs. Our general and administrative expenses per
Mcfe produced have decreased in each of the past three years from $0.21 per Mcfe
in 1996 to $0.14 per Mcfe in 1997 and to $0.10 per Mcfe in 1998. Supervision
fees netted from general and administrative expenses were $2.7 million for 1998,
$2.6 million for 1997 and $2.2 million for 1996.

     DD&A increased 62% in 1998 and 47% in 1997, primarily due to additions to
our reserves and associated costs and to the related sale of increased
quantities of oil and gas produced from the added properties, which increased
54% in 1998 and 31% in 1997. Our DD&A rate per Mcfe of production was $0.85 in
1996, $0.95 in 1997 and $1.01 in 1998, reflecting variations in the per unit
cost of reserves additions.

     Our production costs in 1998 increased $4.4 million, or 50%, over such
expenses in 1997, while those expenses in 1997 increased $2.6 million, or 43%,
over 1996 costs. The increases in each of the periods primarily relate to the
increases in our oil and gas sales volumes. Our production costs per Mcfe
produced were $0.34 in 1998, $0.35 in 1997 and $0.32 in 1996. Supervision fees
netted from production costs were $2.7 million for 1998, $2.6 million for 1997
and $2.2 million for 1996.

     Interest expense in both 1998 and 1997 on our convertible notes due 2006,
including amortization of debt issuance costs, totaled $7.5 million, compared to
$0.7 million on our convertible notes due 2006 and $1.0 million on the 1993
convertible debentures in 1996. Interest expense on our credit facilities,
including commitment fees, totaled $5.6 million in 1998, $0.1 million in 1997
and $1.1 million in 1996. Thus, 1998's interest expense totaled $13.1 million,
of which $4.4 million was capitalized. The 1997 total interest expense was $7.6
million, of which $2.6 million was capitalized. The 1996 total interest expense
was $2.8 million, of which $2.1 million was capitalized. We capitalized that
portion of the interest related to our exploration, partnership and foreign
business development activities. The increase in interest expense in 1998 was
attributable to the increase in amounts outstanding under our credit facilities.
The increase in interest expense in 1997 was attributable to the larger
outstanding principal amount of $115.0 million on the convertible notes due 2006
compared to $28.75 million principal amount of 1993 convertible debentures,
offset to some degree by larger outstanding balances under our credit facilities
in 1996 and by the $2.4 million in interest income earned in 1997 on the portion
of the net proceeds of the convertible notes due 2006 invested pending use.

     In the third quarter of 1998, we took a non-cash write down of oil and gas
properties, as discussed in Note 1 to the Consolidated Financial Statements.
Lower prices for both oil and gas at September 30, 1998 necessitated a pre-tax
domestic full-cost ceiling write down of $77.2 million, or $50.9 million after
tax. Also in the third quarter, we re-evaluated the timing of the recovery of
our capitalized unproved properties costs in Russia due to economic and
political uncertainty and impaired our total investment of $10.8 million. In
addition, the international economic uncertainty and currency concerns in
Venezuela combined with the price volatility and severe tightening of
international credit markets, also caused us to impair our capitalized unproved
properties costs in Venezuela of $2.8 million. The re-evaluation of the unproved
properties costs in these two countries resulted in a separate non-cash pre-tax
charge to earnings of $13.6 million, or $9.0 million after tax. We are currently
expensing costs in these countries. The combination of the non-cash full-cost
domestic ceiling write down and the non-cash foreign impairment charges resulted
in a combined non-cash charge to earnings of $90.8 million pre-tax, or $59.9
million after tax. We currently have no intention to make any additional
investments in Russia.

     At December 31, 1998, our full-cost ceiling cushion was approximately $25.0
million. Subsequent to year-end 1998, oil and gas prices have increased,
providing a substantially larger full-cost ceiling cushion.

     Net Income. Before the non-cash write down of oil and gas properties in
1998, our net income of $11.7 million was 48% lower, and basic EPS of $0.71 was
47% lower, than net income of $22.3 million and basic EPS of $1.35 in the same
period for 1997. This decrease primarily reflected the effect of the 33%
decrease in oil prices and 22% decrease in gas prices, while costs and expenses
increased in general proportion to the 54% increase in production volumes
discussed above.

     Our 1997 net income of $22.3 million was 17% higher and basic EPS of $1.35
was 6% higher than net income of $19.0 million and basic EPS of $1.27 in 1996.
This increase in net income primarily reflected the effect of a 31% increase in
oil and gas sales revenues as a result of a 36% increase in gas production, an
8% increase in crude oil production, and a slight 4% increase in gas prices
received, offset by an 11% decrease in oil prices received. The lower percentage
increase in basic EPS reflects a 10% increase in weighted average shares
outstanding in 1997 as a result of the conversion of the 1993 convertible
debentures into 2.34 million shares of common stock in the third quarter of
1996.

LIQUIDITY AND CAPITAL RESOURCES

     During the first six months of 1999, we relied upon internally generated
cash flows of $28.3 million to fund capital expenditures of $23.2 million. We
expect internally generated cash flows, together with limited borrowings under
our credit facility, to provide cash and working capital for the remainder of
1999. During 1998, we used $138.3 million of borrowings under our credit
facilities, along with our internal cash flows of $54.2 million, to fund capital
expenditures of $183.8 million.

     Net Cash Provided by Operating Activities. For the first half of 1999, net
cash provided by our operating activities increased by 11% to $28.3 million, as
compared to $25.5 million during the first six months of 1998. The 1999 increase
of $2.8 million was primarily due to $13.2 million of additional oil and gas
sales. However, this increase is substantially offset by the $7.4 million
increases in both oil and gas production costs and in interest expense.

     Our operating activities provided net cash of $54.2 million in 1998, $55.3
million in 1997 and $37.1 million in 1996. The slight decrease of $1.1 million
in 1998 was primarily due to the offset of our 54% increase in production
volumes by:

     - the 25% decrease in average commodity prices received;

     - the associated 50% increase in oil and gas production costs; and

     - a decrease in interest income and an increase in interest expense due to
       our use of the net proceeds of our convertible notes due 2006, resulting
       in increased bank borrowings during 1998.

                                      S-25
<PAGE>   26

The 1997 increase in net cash of $18.2 million was primarily due to $16.5
million more in cash flows from oil and gas sales and interest income.

     Credit Facility. At June 30, 1999, we had outstanding borrowings of $140.0
million under our credit facility. At December 31, 1998, we had outstanding
borrowings of $146.2 million under the credit facility. At July 1, 1999, our
credit facility consisted of a $250.0 million revolving line of credit with a
$161.0 million borrowing base. After we apply the net proceeds of both offerings
to reduce our bank debt, we will have no outstanding balance under the credit
facility and a borrowing base of $140.0 million. Our $250.0 million revolving
credit facility includes, among other restrictions, requirements to maintain
certain minimum financial ratios principally pertaining to working capital, debt
and equity ratios, and limitations on incurring other debt. We are currently in
compliance with the provisions of our credit facility.

     Debt Maturities. Our credit facility extends until August 18, 2002. Our
convertible notes mature November 15, 2006.

     Working Capital. Our working capital increased from $3.8 million at
December 31, 1998 to $5.2 million at June 30, 1999, as our internally generated
funds exceeded our capital expenditures.

     Due to the nature of our business, the individual components of our working
capital fluctuate considerably from period to period. We incur significant
working capital requirements in our role as operator of approximately 836 wells
and in our drilling and acquisition activities. In this capacity, we are
responsible for day-to-day cash management, including the collection and
disbursement of oil and gas revenues and related expenses.

     Common Stock Repurchase Program. In March 1997, we commenced a common stock
repurchase program which terminated pursuant to its terms as of June 30, 1999.
We spent $13.3 million through June 30, 1999 to acquire 927,774 shares at an
average cost of $14.34 per share. In March 1999, we used 68,318 shares of
treasury stock to fund our employer matching in the 401(k) program for our
employees. The indenture governing the terms of the notes being sold in this
offering will limit our right to make stock repurchases in the future.

     Capital Expenditures. During the first six months of 1999, we used $23.2
million to fund capital expenditures for property, plant and equipment. These
capital expenditures included:

     - $15.7 million spent for drilling costs, both development and exploratory;

     - $6.7 million of domestic prospect costs, principally prospect leasehold,
       seismic and geological costs of unproved prospects for our account;

     - $0.4 million invested in New Zealand; and

     - $0.4 million spent primarily for computer equipment, software and
       furniture and fixtures.

     In the remaining six months of 1999, we expect to spend approximately $31.0
million on capital expenditures, including investments in all areas in which
investments were made during the first six months of the year as described
above. Ten wells were drilled in the first half of 1999, and seven were
completed as successful development wells. For the second half of 1999, we
anticipate drilling an additional ten wells, made up of eight development wells
and two exploratory wells. We estimate capital expenditures for 1999 to be
approximately $54.2 million, which is substantially lower than prior years.
Approximately $36.0 million of the 1999 budget is allocated to drilling,
primarily in our core fields. The remaining $18.2 million is targeted
principally for leasehold, seismic and geological costs of unproved properties.
We believe that 1999's anticipated internally generated cash flows, together
with limited borrowings under our credit facility, will be sufficient to finance
the costs associated with our currently budgeted remaining 1999 capital
expenditures.

     Our capital expenditures were approximately $183.8 million for 1998, $132.0
million for 1997 and $91.5 million for 1996. During 1997, we relied upon net
proceeds from the sale in 1996 of $115.0 million of convertible notes due 2006
and on internally generated cash flows, along with $7.9 million of bank
borrowings, to fund capital expenditures. During 1998, we used $138.3 million of
bank borrowings, along
                                      S-26
<PAGE>   27

with internal cash flows of $54.2 million, to fund capital expenditures. Capital
expenditures in 1998 included:

     - $59.5 million, or 32%, spent on producing properties acquisitions, almost
       all of which was for the Brookeland and Masters Creek Fields acquisition;

     - $54.8 million, or 30%, spent on developmental drilling, primarily in the
       AWP Olmos and Giddings Fields;

     - $12.6 million, or 7%, spent on exploratory drilling;

     - $34.7 million, or 19%, spent on domestic prospect costs, principally
       leasehold, seismic, and geological costs of unproven prospects for our
       account, including $15.2 million for leaseholds in the Brookeland and
       Masters Creek Fields acquisition;

     - $15.0 million, or 8%, spent for the purchase of a 20% interest in two gas
       processing plants in the Brookeland and Masters Creek Fields acquisition;

     - $3.9 million, or 2%, invested in foreign business opportunities,
       consisting of $2.9 million in New Zealand, $0.4 million in Venezuela and
       $0.6 million in Russia, as described in Note 8 to the Consolidated
       Financial Statements;

     - $2.2 million, or 1%, spent on field compression facilities; and

     - $1.0 million, or 1%, spent on fixed assets.

     In 1998, we participated in drilling 61 development wells and 14
exploratory wells, of which 53 development wells and 5 exploratory wells were
successes. The steady growth in the amount of our unproved property to $56.0
million, which is not being amortized, is indicative of our shift to a focus on
drilling activity in recent years as we acquired prospect acreage in or near our
core fields, such as the acquisition of substantial leasehold positions in the
Brookeland and Masters Creek Fields, and in the pursuit of our New Zealand
activities.

YEAR 2000

     The Year 2000 issue arose because many existing computer programs use only
the last two digits to refer to a year. Therefore, these programs cannot
distinguish between the years 1900 and 2000. Errors of this type can result in
systems failures, miscalculations and the disruption of normal business
activities. We formed a task force during 1998 to address the Year 2000 issue
and to prepare our business systems for the Year 2000. This task force developed
our Year 2000 program, which includes testing our in-house business systems and
field operations systems, reviewing Year 2000 compliance certifications and
reports issued by third parties, upgrading or replacing noncompliant systems and
preparing a contingency plan for unforeseen difficulties. We are continuing to
implement this plan in an effort to make our operations capable of addressing
the Year 2000.

     Our in-house business systems are almost entirely comprised of
off-the-shelf software. During the first half of 1999, we continued to test any
in-house software which has not been certified by the licensor as Year 2000
compliant. To date, 80% of these systems have been tested, certified as
compliant by the licensor of the software, or categorized as not date specific.
We are continuing to identify any software which experiences difficulties
distinguishing the Year 2000. We solve most of these potential Year 2000
problems by upgrading or replacing this software, which we test as it is
installed. We have not experienced any material system disruption during testing
procedures, and based on testing and remedial activities, we believe that we
will be able to resolve potential Year 2000 problems concerning our financial
and administrative systems. We expect to complete testing during the third
quarter of 1999 and continue remedial actions as needed.

     Our core business functions consist of oil and gas exploration. The systems
and equipment which perform these functions are primarily non-information
technology systems which are not date specific.

                                      S-27
<PAGE>   28

Although we cannot predict all effects of the Year 2000 issue, based on our
review, we expect that our field operation systems will continue to perform
normally when faced with the Year 2000.

     In the event of unforeseen Year 2000 difficulties, employees can manually
perform most, if not all, in-house functions, although such acts may require
additional time to perform. Our most reasonably likely worst case scenario would
therefore involve a prolonged disruption of external power sources upon which
our core field operations equipment relies.

     In our business, we also depend on third parties such as pipeline
operations to whom we sell gas, customers and suppliers, any one of whom could
be prone to Year 2000 problems that we cannot assess or detect. We have
contacted our major purchasers, customers, suppliers, financial institutions and
others with whom we conduct business to assess their Year 2000 program and to
inform them of our Year 2000 review. Approximately 60% have responded that they
are compliant, approximately 30% have confirmed that they are continuing to
address the Year 2000 issue and the remainder have not responded.

     Based on these third party representations and results of our testing
phase, we are continuing to develop our contingency plan, such as using on-site
generators and identifying substitute suppliers. We do not believe that costs
incurred to address the Year 2000 issue will have a material effect on our
results of operations or our liquidity and financial condition. We estimate our
total cost to address the Year 2000 issue to be less than $150,000, most of
which will be spent during the testing phase. We have used and will continue to
use both internal and external resources to complete our Year 2000 program and
perform tasks necessary to address the Year 2000 problem.

                            BUSINESS AND PROPERTIES

GENERAL

     Swift Energy Company, a Texas corporation formed in October 1979, engages
in the development, exploration, acquisition and operation of oil and gas
properties with a primary focus on U.S. onshore gas reserves located in Texas
and Louisiana. As of December 31, 1998, we had interests in over 1,750 oil and
gas wells located in eight states. We operated 836 of these wells representing
91% of our proved reserves. At year-end 1998, we had estimated proved reserves
of 436.1 Bcfe, of which approximately 81% was gas. Our estimated proved reserves
are concentrated 84% in Texas and 13% in Louisiana.

     We currently focus primarily on development and exploration in four major
fields:

Masters Creek  Western Louisiana            12%               21%
</TABLE>

     The AWP Olmos Field is characterized by long-lived reserves, which means we
expect these reserves to be steadily produced over a long period of time. The
Brookeland, Giddings and Masters Creek Fields are characterized by shorter-lived
reserves with high initial rates of production that decline rapidly. We believe
these shorter-lived reserves complement our long-lived reserves in the AWP Olmos
Field. Based on 1998 year-end proved reserves and 1998 production, our average
reserve life was 11.2 years. Approximately 93% of our 1998 year-end proved
reserves and 88% of our 1998 production were concentrated in these four fields.

     We purchased interests in the Brookeland and Masters Creek Fields from
Sonat Exploration Company in the third quarter of 1998 for approximately $85.6
million in cash. Of this purchase price, $55.3 million was spent for producing
properties, $15.0 million for 20% interests in two natural gas plants and $15.3
million for leasehold properties. This acquisition extended our holdings in the
Austin Chalk formation. We expect to use our operating expertise in this
geological trend to continue to successfully develop and exploit the new
acreage.

     As of December 31, 1998, the Brookeland and Masters Creek Fields consisted
of 162 producing wells, 115 of which were operated by us, the production
facilities associated with these wells, 23 saltwater disposal wells and
approximately 444,000 net acres. Our 1998 production from the Brookeland and
Masters Creek Fields, which began in the third quarter of 1998, was
approximately 11.6 Bcfe and representing approximately 30% of our total 1998
production. Of this production, approximately 56% was oil. The production for
these fields during the first six months of 1999 was approximately 54% of our
total production. At year-end 1998, the Brookeland and Masters Creek Fields
contained 130.5 Bcfe of estimated proved reserves, an increase of 43% from the
91.1 Bcfe at the effective date of the acquisition. Approximately 58% of these
year-end reserves were natural gas and 59% were proved developed reserves.

     In addition to our continuing production, development and exploration
activities in the AWP Olmos, Brookeland, Giddings and Masters Creek Fields, we
are currently pursuing development and exploration activities in the Gulf Coast
Basin and onshore New Zealand.

     During 1997 and 1996, our growth resulted primarily from the acquisition of
additional acreage and increased drilling activities in the AWP Olmos and
Giddings Fields. Capital expenditures for development and exploration drilling,
primarily in these two fields, were $101.0 million in 1997 and $71.8 million in
1996, while capital expenditures for acquisitions were $8.4 million in 1997 and
$1.5 million in 1996. As a result of lower oil and gas prices during 1998, we
reduced capital expenditures for drilling and redirected a portion of those
expenditures to the acquisition of producing properties, primarily the
Brookeland and Masters Creek Fields. In 1998, development and exploration
drilling expenditures for the year,

                                      S-29
<PAGE>   30

concentrated in the first half of the year, totaled $67.4 million. We spent
$59.5 million for the acquisition of producing properties in 1998, almost all in
the third quarter of 1998.

     In further response to lower oil and gas prices in 1998, we budgeted
capital expenditures of $54.2 million for 1999. We allocated $36.0 million for
drilling, of which $31.3 million is for development drilling and $4.7 million is
for exploratory drilling. The remaining $18.2 million of this budget represents
the leasing, seismic survey and geological research costs of prospects. We are
funding this budget primarily through the use of internally generated cash
flows, together with limited borrowings under the credit facility.

BUSINESS STRATEGY

     Our strategy is to increase our reserves and production through both
drilling and acquisitions, shifting the balance between the two activities in
response to market conditions. In addition, we seek to enhance the results of
our drilling and production efforts through the implementation of advanced
technologies. The elements of our strategy may be further described as follows:

     Development and Exploration Drilling Activities. Developmental wells are
those drilled within the presently productive area of an oil or gas reservoir.
Exploratory wells are those drilled either in search of a new oil or gas
reservoir or to greatly extend the known limits of a previously discovered
reservoir. We pursue a controlled risk approach to developmental and exploratory
drilling, focusing our activities on specific U.S. regions in which our
technical staff has considerable experience and which are located close to known
producing horizons. We seek to minimize our exploration risk by investing in
multiple prospects, farming out interests to third parties, using advanced
technologies and drilling in diverse types of geological formations. We use
basin studies to analyze targeted formations based on their potential size, risk
profile and economic characteristics.

     We added 118 Bcfe of proved reserves through drilling in 1996 and 120 Bcfe
of proved reserves in 1997. In 1998, we deferred drilling projects scheduled for
the second half of the year in response to lower oil and gas prices.
Accordingly, reserves added by drilling decreased to 74 Bcfe in 1998. The 1998
additions were a result of a success rate of 87% for development wells, or 53
out of 61 drilled, and a success rate of 36% for exploratory wells, or 5 out of
14 drilled.

     Our development and exploration activities are conducted by our staff of
professionals, including reservoir engineers, geologists, geophysicists,
petrophysicists, landmen and drilling and production engineers. We believe that
one of the keys to our success has been our team approach, which integrates
multiple disciplines to maximize efficient use of information leading to
drillable projects.

     Strategic Acquisitions. We use a disciplined, market-driven approach to
acquisitions. Generally we seek to acquire properties with the potential for
additional reserves and production through development and exploration efforts.
In 133 transactions since 1979, we have acquired approximately $537.5 million of
producing oil and gas properties on behalf of ourselves and our co-investors. We
acquired, for our own account, approximately $181.0 million of producing
properties, with original proved reserves estimated at 279.9 Bcfe. Our producing
property acquisition expenditures in the past three years were $59.5 million in
1998, $8.4 million in 1997 and $1.5 million in 1996. Our acquisition costs have
averaged $0.52 per Mcfe over this three-year period.

     Use of Advanced Technologies. We have increasingly used advanced seismic
technology to enhance the results of our drilling and production efforts,
including 2-D and 3-D seismic analysis, amplitude versus offset studies and
detailed formation depletion studies. We have a number of computer workstations
from which seismic data is analyzed and enhanced with advanced software
programs, including three Landmark Systems(R) workstations. As a result, we have
developed a significant internal seismic expertise and have compiled an
extensive library of seismic data.

     We began our horizontal drilling program in the Austin Chalk trend in 1992.
Our success in the Austin Chalk trend has been due to the use of recent
technological advances that facilitate the drilling of horizontal wells. These
technological advances include the development of a durable down-hole motor that
                                      S-30
<PAGE>   31

is mounted directly behind the drill bit and down-hole
measurement-while-drilling instruments that signal the exact location of the
bit, allowing the operators to ensure that the drilled hole stays within the
targeted interval. We have also introduced underbalanced drilling and the
completion of an increasing number of dual-lateral wells. A successful
horizontal drilling program also requires a knowledge of the location of the
potential hydrocarbon traps, or natural vertical fractures, within the trend.
Our team has expertise in all the disciplines necessary for a successful
program, including years of experience in directional and horizontal drilling.

     We use a variety of advanced recovery techniques, including water flooding
and acid treatments, hydraulic fracturing, fracture extension and coiled tubing.
Hydraulic fracture technique stimulates production from wells drilled in tight,
low-permeability sand, as is found in the AWP Olmos Field. The fractures provide
pathways through which oil and gas can flow into the well bore. Fracture
extension, or re-fracing, means that wells that have already been producing, for
months or years, undergo hydraulic fracturing for a second time. When wells
undergo a second fracturing process, the original fractures are extended or new
fractures are created, or both. This allows the wells to access additional
reserves and increase their production rates. As a result of the low commodity
prices of 1998, fracture extensions became a more economic approach for
increasing production. During 1998, our fracture extension program was increased
from 40 wells to 103 wells. The use of small-diameter coiled tubing velocity
strings in older wells speeds the upward flow of the natural gas and prevents
the buildup of liquids that clog the well bore. We believe that the application
of fracturing technology and coiled tubing significantly increases production
and decreases costs in the AWP Olmos Field. Through direct computer access to
the AWP Olmos Field, we monitor both fracturing operations and routine
production from our Houston headquarters. This computer telemetry increases our
efficiency.

     During the first half of 1999, we introduced dendritic fracturing
techniques to the Brookeland Field. Dendritic fracturing is the pumping of large
quantities of water and small amounts of hydrochloric acid at high injection
rates down a well bore out into the formation's natural fractures, some of which
have become clogged. The objective is to clean out the fractures to improve
hydrocarbon flow into the well bore.

PRIMARY PROPERTIES

     AWP Olmos Field. Our largest contiguous operation is in the AWP Olmos Field
in south Texas. As of December 31, 1998, we owned approximately 37,000 net acres
in the AWP Olmos Field. We have extensive expertise in this area and a long
history of experience with the low-permeability, tight-sand formations typical
of this field, having acquired our first acreage in this field in 1988. The
reserves in this field are over 92% gas. At year-end 1998, we owned interests in
and served as operator of 447 wells in this field producing gas from the Olmos
Sand formation at a depth of approximately 10,000 feet. We or entities we manage
own nearly 100% of the working interests in all wells in which we have an
interest in this field.

     In 1998, we drilled 33 development wells in the AWP Olmos Field, 31 of
which were successful. We increased our leasehold position in the field in 1998
by obtaining additional acreage and will, if warranted, acquire more acreage in
the future. At year-end 1998, we had 140 proved undeveloped locations. Our
planned 1999 capital expenditures of $12.0 million in this area are focused on
fracture extensions and further use of coiled tubing velocity strings.

     Brookeland Field. As of December 31, 1998, we owned drilling and production
rights in 223,000 gross acres, 163,000 net acres and 15,000 fee mineral acres
containing substantial proved undeveloped reserves. This field was also part of
the Sonat acquisition in 1998. The Brookeland Field is located in southeast
Texas near the border of Louisiana in Jasper and Newton counties. This area
primarily contains horizontal wells producing gas from the Austin Chalk
formation. At year-end 1998, we had 36 proved undeveloped locations. We plan to
drill seven infill development wells in 1999, with three to be operated by us
and four by Union Pacific. Our planned 1999 capital expenditures in this area
are $6.2 million.

                                      S-31
<PAGE>   32

     Giddings Field. As of December 31, 1998, we owned drilling and production
rights in approximately 113,000 net acres in the Giddings Field. This field is
located in Washington, Colorado, Fayette and Austin counties in southeast
central Texas, known as the Quad Counties area, where we continue to selectively
acquire acreage. Since 1992, we have participated in 78 horizontal wells in the
Giddings Field with an 87% success rate. The reserves in this field are
approximately 90% gas. In 1998, we drilled 16 successful development wells out
of 19 and drilled two successful exploratory wells out of four. We plan to drill
an additional development well and one exploratory well in the second half of
1999. We attribute our success in the Giddings Field, which primarily produces
from the Austin Chalk formation, to our ability to identify hydrocarbon-bearing
fractures through our expertise in geological and geophysical analyses, and to
our ability to drill and operate horizontal wells through advanced horizontal
drilling techniques. In addition to the Austin Chalk formation, we have targeted
exploration projects in the Edwards Lime formation. At year-end 1998, we had
nine proved undeveloped locations. Our planned 1999 capital expenditures in this
field are $2.7 million.

     We have established a number of joint ventures with industry partners to
further develop and explore this field, including:

          Chevron USA Production Company. The joint venture encompasses a
     development area of 144,000 gross acres in Fayette, Colorado and Austin
     counties, with 70,000 net acres currently under lease. Swift and Chevron
     each own a 50% working interest, and we serve as operator, with any
     additional leased acreage to be shared and operated on the same basis. To
     date, we have drilled two exploratory wells, one of which was successful.

          Union Pacific Resources.

         - We have a 25% working interest in a joint development area covering
           approximately 17,000 gross acres in Washington County, Texas. Union
           Pacific acts as operator in this venture.

         - We own a 50% working interest in another joint development area also
           in Washington County covering approximately 6,300 gross acres. Union
           Pacific acts as operator in this venture.

         - We own a 75% working interest and serve as operator for a joint
           venture covering approximately 8,100 gross acres in Washington and
           Austin counties.

     Masters Creek Field. As of December 31, 1998, we owned drilling and
production rights in 413,000 gross acres, 281,000 net acres and 141,000 fee
mineral acres in this field containing substantial proved undeveloped reserves.
This field was part of the August 1998 Sonat acquisition. It is located near the
Texas-Louisiana border in the two parishes of Vernon and Rapides in Louisiana.
The Masters Creek Field contains horizontal wells producing both oil and gas
from the Austin Chalk formation.

     In the first half of 1999, we drilled a successful development well in
which we have an 80% working interest. Because of the success of this well, we
plan to begin drilling an additional well in this field during the third quarter
of 1999. At year-end 1998, we had ten proved undeveloped locations with an
additional proved undeveloped location just west of the field. Our planned 1999
capital expenditures in this area are $7.3 million.

OTHER PROPERTIES

     Gulf Coast Basin. This area includes all the Texas counties and Louisiana
parishes along the Gulf Coast extending into Mississippi and Alabama. In 1998,
we drilled three successful development wells out of six and two successful
exploratory wells out of three in this area, following one successful
development well and four successful exploratory wells drilled in 1997. In 1999,
one development well and two exploratory wells are scheduled for drilling in the
Gulf Coast Basin.

     During 1997, we acquired 1,920 gross acres in Jim Hogg County, Texas, in
which we own a minimum 75% working interest. Our successful exploratory well
drilled to the Queen City formation in 1997 was

                                      S-32
<PAGE>   33

followed by three successful development wells and a successful exploratory well
in 1998. Further work in the area is awaiting a fracture extension program to be
carried out in 1999 to assess the full potential of the area.

FOREIGN ACTIVITIES

     New Zealand. Since October 1995, the New Zealand Minister of Energy has
issued Swift two petroleum exploration permits. The first permit covered
approximately 65,000 acres in the onshore Taranaki Basin of New Zealand's North
Island, and the second covered approximately 69,300 adjacent acres. In March
1998, we surrendered approximately 46,400 acres covered in the first permit, and
the remaining acreage has been included as an extension of the area covered in
the second permit, leaving us with only one expanded permit. Under the terms of
the expanded permit, we must drill one exploratory well prior to August 12,
1999, which we have commenced. We have fulfilled all other obligations under the
permit.

     On October 23, 1998, we entered into separate agreements with Marabella
Enterprises Ltd., a subsidiary of Bligh Oil & Minerals N.L., an Australian
company, to obtain from Marabella a 25% working interest in another New Zealand
petroleum exploration permit and provide Marabella a 5% interest in our permit.
During the fourth quarter of 1998, Marabella drilled an unsuccessful exploration
well on its permit. Accordingly, we charged $400,000 against earnings,
representing costs of this well. We also agreed in principle to participate with
Marabella in an additional permit as a 25% working interest owner. Additionally,
Swift obtained a 7.50% working interest in another New Zealand permit from
Antrim Oil and Gas Limited, and Antrim became a 5% participant in our permit. On
this permit, an exploratory well was drilled and temporarily abandoned during
the second quarter of 1999, and we charged our $290,000 portion of the costs on
this well to earnings. As of June 30, 1999, our investment in New Zealand
totaled approximately $5.4 million. We included these costs in the unproved
properties portion of oil and gas properties. We are currently exposed to the
risk of another write down or impairment of our properties in New Zealand. SEE,
"RISK FACTORS."

     Russia. Under a participation agreement with Senega, a Russian Federation
joint stock company, in which we have an indirect interest of 1%, we retain a 6%
net profits interest in the Samburg Field, located in western Siberia. Due to
the prevailing economic conditions in Russia, we impaired all of $10.8 million
of costs after tax for our properties in Russia. We currently expense any
amounts spent here as they are incurred and have no intention to make any
additional investments in this country.

     Venezuela. We have entered into an agreement with Tecnoconsult, S.A., and
Corporation EDC, S.A.C.A., Venezuelan companies, to jointly formulate and submit
a proposal to Petroleos de Venezuela, S.A. for the construction and operation of
a methane pipeline. Currently, the technical and economic feasibility of the
project is under study. Due to the prevailing economic conditions in Venezuela,
we impaired all $2.8 million of costs after tax for our properties in Venezuela
during the third quarter of 1998, and are now expensing any amounts spent there.

OIL AND GAS RESERVES

     The following table presents information regarding proved reserves of oil
and gas attributable to our interests in producing properties as of December 31,
1998, 1997 and 1996 based on proved reserves reports prepared by us and audited
by H. J. Gruy and Associates, Inc., Houston, Texas, independent petroleum
engineers. Gruy based its estimates upon review of production histories and
other geological, economic, ownership and engineering data provided by us. All
calculations of estimated reserves have been made in accordance with SEC
guidelines and, except as otherwise indicated, give no effect to federal or
state income taxes otherwise attributable to estimated future cash flows from
the sale of oil and gas. The PV-10 Value is the estimated future net revenue to
be generated from the production of proved reserves, discounted to present value
using an annual discount rate of 10%. These amounts are calculated net of
estimated production costs and future development costs, using prices and costs
at the time of the estimate, without escalation and without considering
non-property related expenses, such as general and

                                      S-33
<PAGE>   34

administrative expenses, debt service, future income tax expense, or
depreciation, depletion and amortization. We have interests in some tracts
estimated to have additional hydrocarbon reserves that cannot be classified as
proved which are not reflected in the following table. The proved reserves
presented also exclude any reserves attributable to the volumetric production
payment.

     Proved reserves are an estimate of oil and gas to be recovered in the
future. Reservoir engineering, the process used to estimate reserves, is a
subjective process involving the estimation of the sizes of underground
accumulations of oil and gas that cannot be measured in an exact way. The
accuracy of any reserves estimate is a function of the quality of available data
and of engineering and geological interpretation. Reserve reports of other
engineers might differ from those we have used. Results of drilling, testing and
production after these estimates may justify revisions of these estimates.
Future prices received for the sale of oil and gas may be different from those
used in preparing these estimates. The amounts and timing of future operating
and development costs may also differ from those used. Therefore, reserve
estimates often differ from the quantities of oil and gas ultimately recovered.
These estimates may not accurately predict the present value of future net cash
flows from oil and gas reserves.

     A portion of our proved reserves has been accumulated through our interests
in the limited partnerships for which we serve as general partner. The estimates
of future net cash flows and their present values, based on period end prices,
assume that some of the limited partnerships in which we own interests will
achieve payout status in the future. As of December 31, 1998, 17 of the 80
limited partnerships managed by us have achieved payout status.

     Changes in crude oil and gas prices at the end of each year affect quantity
estimates and the estimated present value of proved reserves. While our total
proved reserves quantities, on an equivalent Bcfe basis, at year-end 1998
increased by 21% over reserves quantities a year earlier, the PV-10 Value of
those reserves decreased 3% from the PV-10 Value at year-end 1997. This decrease
was due almost entirely to pricing declines at year-end 1998 as compared to
year-end 1997, which more than offset the 21% Bcfe increase in reserves
quantities. Product prices for gas declined 20% during 1998 from year-end 1997,
accompanied by a 29% decrease in the price of oil between the two dates. No
other reports on our reserves have been filed with any federal agency.

REPLACEMENT OF RESERVES AND PRODUCTION

     We increased our proved reserves from 90.1 Bcfe at year-end 1993 to 436.1
Bcfe at year-end 1998, resulting in the replacement of 449% of production during
this period. Due to our geographic concentration and increased production, our
general and administrative expenses decreased from $0.35 per Mcfe in 1994 to
$0.10 per Mcfe in 1998. Production costs decreased from $0.39 per Mcfe in 1994
to $0.34 per Mcfe in 1998. As a result of increased production and decreased
operating costs per Mcfe, net cash provided by operating activities grew at an
annual compounded growth rate of 50% for the five-year period ended December 31,
1998.

     In 1998, we increased our proved reserves by 21%, resulting in the
replacement of 296% of 1998 production. Over the five-year period ended December
31, 1998, our average replacement cost was $0.88 per Mcfe. As a result of both
acquisition and drilling activity, 1998 production increased 54% over 1997
production.

OPERATIONS

     We generally seek to be the operator for wells in which we have a
significant economic interest. As operator, we design and manage the development
of a well and supervise operation and maintenance activities on a day-to-day
basis. We do not own drilling rigs or other oilfield services equipment used for
drilling or maintaining wells on properties we operate. Independent contractors
supervised by us provide all the equipment and personnel. We employ drilling,
production and reservoir engineers, geologists and other specialists who work to
improve production rates, increase reserves, and lower the cost of operating our
oil and gas properties.

     Oil and gas properties are customarily operated under the terms of a joint
operating agreement. These agreements usually provide for reimbursement of the
operator's direct expenses and for payment of monthly per-well supervision fees.
Supervision fees vary widely depending on the geographic location and depth of
the well and whether the well produces oil or gas. The fees for these activities
paid to us in 1998 ranged from $200 to $1,632 per well per month and totaled
approximately $5.5 million.

MARKETING OF PRODUCTION

     We typically sell our oil and gas production at market prices near the
wellhead, although in some cases it must be gathered by us or other operators
and delivered to a central point. Gas production is primarily sold in the spot
market on a monthly contract basis, while we sell our oil production at
prevailing market prices at the time of sale. We do not refine any oil we
produce. For the year ended December 31, 1998, two purchasers accounted for
approximately 16% and 10% of our total revenues. However, due to the
availability of other purchasers, we do not believe that the loss of any single
oil or gas purchaser or contract would materially affect our revenues.

     We have entered into gas processing and gas transportation agreements for
our gas production in the AWP Olmos Field with Pacific Gas & Electric
Corporation and in the Giddings Field with Aquila Southwest Pipeline
Corporation. We believe that these contracts adequately provide for our gas
purchase and processing needs. The prices we receive are redetermined monthly to
reflect the current gas price.

     We sell our oil production from the Brookeland and Masters Creek Fields to
purchasers at prevailing market prices. Our gas production from the Brookeland
and Masters Creek Fields is processed under long-term gas processing contracts
with Duke Energy Field Services, Inc., utilizing the gas processing plants in
which we own a 20% interest.

     The following table summarizes sales volumes, sales prices and production
cost information for our net oil and gas production for the first half of 1999
and the years ended December 31, 1998, 1997 and

indirectly, and produced to our interest after deducting royalty and other
interests.

SEE, NOTE 1 TO THE CONSOLIDATED FINANCIAL STATEMENTS.

PRICE RISK MANAGEMENT

     Market prices of oil and gas fluctuate and can adversely affect our
operating results. To mitigate some of this risk, we engage periodically in
limited hedging activities, but only to the extent of buying price floors for
portions of our oil and gas production and that of the limited partnerships we
manage. Costs and benefits derived from these price floors are accordingly
recorded as a reduction or increase, as appropriate, in oil and gas sales
revenue and have not been significant in any recent years. We amortize the costs
to purchase these floors over the option period.

     During 1998, we entered into various gas price floor contracts throughout
the year that covered between 500,000 and 3,000,000 MMBtu of gas at prices from
$1.80 to $2.10. For the months of January and February 1998, 60,000 Bbls of oil
production were covered each month, providing for a minimum price of $18.00 per
Bbl. Costs related to 1998 price floor activities totaled approximately
$377,000, with benefits of approximately $101,000 being received, resulting in a
cost of approximately $276,000 or $0.007 per Mcfe.

     During the first six months of 1999, we have entered into various price
floor contracts that ranged from $1.60 to $2.00 for gas on volumes from
1,000,000 to 2,800,000 MMBtu, and $12.00 to $16.00 per Bbl for oil on volumes
from 100,000 to 300,000 Bbl. The costs related to 1999 hedging activities
through June 30, 1999 totaled approximately $591,600, with benefits of
approximately $348,400 having been received, resulting in a net cash outflow of
approximately $243,200. The costs related to open contracts as of June 30, 1999
totaled approximately $194,000 and had a fair market value of $10,000.

PARTNERSHIPS

     For many years, we relied on limited partnerships as our principal vehicle
to fund our operations. We have formed 109 limited partnerships which raised a
total of approximately $509.5 million.

     From 1984 to 1995, we formed limited partnerships and joint ventures for
the purpose of acquiring interests in producing oil and gas properties. During
1996 and 1997, the limited partners in 37 partnerships, which had been in
operation for between six and seventeen years and had produced a substantial
majority of their reserves, voted to sell their remaining properties and
liquidate the limited partnerships. Of these partnerships, 10 were the earliest
public income partnerships formed in 1984 through 1986, eight were private
drilling partnerships formed from 1979 to 1985, and 11 were income partnerships,
formed in 1990 and 1991.

                                      S-37
<PAGE>   38

     Between 1993 and 1998, we offered private partnerships formed to engage in
drilling for oil and gas reserves. We serve as the managing general partner of
these entities. As of December 31, 1998, thirteen private drilling partnerships
had been formed, with investor contributions totaling approximately $66.1
million.

     In October 1998, we notified investors in 63 Swift-managed production
partnerships formed between 1986 and 1994 that we had delayed calling investor
meetings to consider the purchase by us of all of the oil and gas properties
owned by these partnerships, which was proposed in March 1998. This decision
principally reflected significant market changes that had occurred and the aging
of the third-party appraisals of these partnership properties during the
regulatory review period. In the second half of 1998, low oil and gas prices
created concern over the propriety of partnerships selling the properties at
that time. Currently, we are re-evaluating the status and operation of these
partnerships and whether to propose some form of liquidating transactions. No
partnerships have been formed or offered in 1999.

LITIGATION

     In 1997, Swift and the Lower Colorado River Authority filed claims against
each other in the District Court of Fayette County, Texas. Swift originally sued
to force the River Authority to assign to Swift leases which the River Authority
had refused to assign, and seeking declaration as to the parties' interests in
the properties involved. The River Authority counterclaimed alleging fraud,
conversion and conspiracy to convert oil and gas. The parties tentatively agreed
to settle this litigation during a mediation held in late May 1999. The
settlement has not been finalized, is subject to negotiation and requisite
approvals of a definitive agreement, and may not be consummated. Swift does not
believe that the ultimate resolution of this case will have a material adverse
impact upon its financial condition or results of operations. SEE, "RISK
FACTORS."

EMPLOYEES

     At June 30, 1999, we employed 167 persons. None of our employees are
represented by a union. Relations with employees are considered to be good.

FACILITIES

     We occupy approximately 75,000 square feet of office space at 16825
Northchase Drive, Houston, Texas, under a ten year lease expiring in 2005. The
lease requires payments of approximately $95,000 per month. We have field
offices in various locations from which our employees supervise local oil and
gas operations.

    for their clients. Of the shares beneficially owned, both Neuberger and
    Management share dispositive power as to all 850,080 shares and share voting
    power as to 661,990 shares of Swift's common stock. Neuberger possesses sole
    voting power as to the remaining 188,090 shares.

(8) Based on a Schedule 13G dated February 12, 1999, Scudder Kemper Investments,
    Inc., an investment adviser registered under Section 203 of the Investment
    Advisers Act of 1990, is deemed beneficial owner of 1,061,930 shares of
    Swift's common stock as a result of serving as an investment adviser to one
    or more investment companies or other managed accounts. Scudder has the sole
    power to dispose of and direct the disposition of all 1,061,930 shares and
    has sole voting power as to 700,830 of such shares of Swift's common stock.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

     In the ordinary course of our business, we acquire interests in
developmental and exploratory oil and gas prospects, and sell portions to
unaffiliated third parties for purposes of diversification. For the past several
years, we have offered interests in certain of these prospects to our executive
officers and other employees. These prospect interests are sold to employees on
terms identical to those at which interests are sold to third party investors in
that prospect. As a result of enhanced drilling activity, the amounts invested
by executive officers in such prospects in 1997 and through mid-1998 increased
significantly over previous years. During 1998, 1997 and 1996, leasehold and
drilling costs incurred by executive officers who invested in these properties
in excess of $60,000 were: A. Earl Swift -- none, $322,261, and $135,957; Terry
E. Swift -- $71,746, $207,426, and $106,621; Virgil N. Swift -- $335,114,
$390,784, and $259,379; John R. Alden -- $183,233, $246,270, and $95,080; Bruce
H. Vincent -- $75,258, $220,458 and none; and only in 1997 for James M.
Kitterman -- $133,068. Some executive officers deferred paying cash for their
investments in such properties, instead assigning the proceeds of production
which over time repay amounts owed, rounded to the nearest $1,000, resulting in
their owing money to Swift from time to time. Prior to 1997, the indebtedness of
any one officer never exceeded $60,000. In late 1997, due to increased levels of
drilling activity, the balances owed to Swift increased, with the greatest
amounts owed Swift in excess of $60,000 occurring in mid-1998 as follows: Virgil
N. Swift -- $174,000; John R. Alden -- $130,000; Bruce H. Vincent -- $124,000;
and James M. Kitterman -- $62,000. At June 30, 1999, no executive officer owed
Swift an amount in excess of $60,000. Individual executive officers are charged
interest on the amount owed Swift at its incremental borrowing rate.

     We operate a substantial number of properties owned by our affiliated
limited partnerships and joint ventures for which we charge operating fees. We
are also reimbursed for direct, administrative, and overhead costs incurred in
conducting the business of the limited partnerships, which totaled approximately
$5.0 million in 1998, $6.3 million in 1997, and $6.1 million in 1996. We were
also reimbursed by the limited partnerships and joint ventures for costs
incurred in the screening, evaluation and acquisition of producing oil and gas
properties on their behalf. These costs totaled approximately $490,000 in 1997
and $250,000 in 1996. We have fulfilled our responsibility of acquiring
properties for such partnerships, as those partnerships are fully invested in
properties. In partnerships whose limited partners voted to sell remaining
properties and liquidate their limited partnerships, the partnerships reimbursed
us for direct, administrative and overhead costs in disposing of these
properties totaling approximately $0.6 million in 1998, $0.7 million in 1997 and
$0.8 million in 1996. In the ordinary course of the affiliated partnerships'
business, they have also purchased properties from Swift.

     Our Employee Stock Ownership Plan, the "ESOP," can borrow money from us to
buy stock for the purpose of distribution to our employees. In September 1996,
the ESOP borrowed money from Swift to purchase 25,000 shares of common stock
from our chairman for $568,750. This debt was repaid in April 1999.

                      DESCRIPTION OF EXISTING INDEBTEDNESS

CREDIT FACILITY

     Our $250.0 million credit facility with a ten bank syndicate had a $161.0
million borrowing base at July 1, 1999, which decreases by $1.5 million a month.
After we apply the net proceeds of both offerings to reduce our bank debt, we
will have no outstanding balance under the credit facility and a borrowing base
of $140.0 million. Depending on the level of outstanding debt, the interest rate
is either the lead bank's base rate, 8.0% at June 30, 1999 or, at our option,
draws which bear interest for specific periods at LIBOR plus 1.125% to 1.75%. We
also pay a commitment fee, which was $114,000 in 1998.

     The weighted average interest rate, with all draws currently under the
LIBOR option, was 6.64% at June 30, 1999, with an outstanding balance at that
date of $140.0 million. The revolving line of credit matures on August 18, 2002.

     The terms of the revolving line of credit include, among other
restrictions, a limitation on the level of cash dividends, not to exceed $2.0
million in any fiscal year, requirements as to maintenance of certain minimum
financial ratios, principally pertaining to working capital, debt and equity
ratios, and limitations on incurring other debt. Since inception, no cash
dividends have been declared on the common stock. Our credit facility limits our
repurchase of shares of common stock to $15.0 million after August 1998. For all
periods presented in this prospectus supplement, we were in compliance with the
provisions of these agreements. FOR A DETAILED DESCRIPTION OF THIS CREDIT
FACILITY, SEE THE CREDIT AGREEMENT WHICH IS ATTACHED AS EXHIBIT 10.1 OF OUR
REPORT ON FORM 10-Q FOR THE PERIOD ENDED SEPTEMBER 30, 1998 FILED ON NOVEMBER
13, 1998.

CONVERTIBLE NOTES DUE 2006

     On November 25, 1996, we issued $115.0 million aggregate principal amount
of 6.25% Convertible Subordinated Notes due November 15, 2006. The following
description of the convertible notes due 2006 is qualified in its entirety by
reference to the indenture for the convertible notes due 2006.

     Payments of principal, interest and premiums under the convertible notes
due 2006 will be subordinated to payments on the notes and are subordinate to
all other senior debt of Swift, including the credit facility. Holders of the
convertible notes due 2006 may convert them into common stock at any time before
maturity at a price of $31.534 per share. This price is subject to adjustment if
certain events occur. Beginning November 15, 1999, we may redeem the convertible
notes due 2006 for cash at 104.375% of principal. This conversion is subject to
restrictions and the conversion rate declines over time to 100.625% in 2005. If
certain changes in control occur, or if our common stock ceases trading on a
national exchange, holders of the convertible notes due 2006 will have the right
to require us to repurchase the convertible notes due 2006 at 101% of the note's
principal amount, plus accrued and unpaid interest to the date of repurchase.
FOR A DETAILED DESCRIPTION OF THE CONVERTIBLE NOTES DUE 2006 AND THEIR
PROVISIONS, SEE THE INDENTURE FILED AS AN EXHIBIT TO THE CONVERTIBLE NOTES
REGISTRATION STATEMENT ON NOVEMBER 19, 1996 OR THE PROSPECTUS FILED WITH THE SEC
ON NOVEMBER 20, 1996.

<PAGE>   46

                            DESCRIPTION OF THE NOTES

     You can find the definitions of certain terms used in this description
under the subheading "-- Certain Definitions," beginning on Page S-62. In this
description, the words "Swift," "we," "us" and "our" refer to Swift Energy
Company and not to any of its subsidiaries. In this description "Notes" refers
to the offered notes and to any additional notes issuable under the Indenture.

     We will issue the Notes under an indenture dated as of July 30, 1999, which
is to be supplemented by a first supplemental indenture to be dated August 4,
1999, referred to as supplemented as the "Indenture," between Swift and Bank
One, N.A., as trustee, the "Trustee." The Indenture is governed by the Trust
Indenture Act of 1939, the "Trust Indenture Act." 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.

     We urge you to read the Indenture because it, and not this description,
defines your rights as a holder of these Notes. A copy of the form of indenture
and the first supplemental indenture are incorporated by reference. The form of
indenture is filed as an exhibit to the Registration Statement, of which this
prospectus supplement forms a part, and the first supplemental indenture will be
filed as an exhibit to a Current Report on Form 8-K.

     We are issuing $125.0 million of Offered Notes now and can issue up to
$100.0 million of additional Notes at later dates under the same Indenture. The
Offered Notes and any additional Notes or series of Notes issued under the
Indenture are collectively referred to as the "Notes." We can issue additional
Notes as part of the same series or as an additional series. Any additional
Notes that we issue in the future will be identical in all respects to the
Offered Notes that we are issuing now, except that Notes issued in the future
will have different issuance prices and issuance dates. We will issue Notes only
in fully registered form without coupons, in denominations of $1,000 and
integral multiples of $1,000.

PRINCIPAL, MATURITY AND INTEREST

     The Notes will mature on August 1, 2009.

     Interest on the Notes will accrue at a rate of 10.25% per annum and will be
payable semi-annually in arrears on February 1 and August 1, commencing on
February 1, 2000. We will pay interest to those persons who were holders of
record on the January 16 and July 16 immediately preceding each interest payment
date.

     Interest on the Notes will accrue from the date of original issuance or, if
interest has already been paid, from the date it was most recently paid.
Interest will be computed on the basis of a 360-day year comprised of twelve
30-day months.

SUBSIDIARY GUARANTIES

     Under the circumstances described below under "-- Certain Covenants
 -- Future Subsidiary Guarantors," Swift's payment obligations under the Notes
may in the future be jointly and severally guaranteed by one or more Subsidiary
Guarantors. The Subsidiary Guaranty of any Subsidiary Guarantor will be an
unsecured senior subordinated obligation of such Subsidiary Guarantor. FOR A
MORE DETAILED DESCRIPTION OF THE SUBORDINATION PROVISIONS, SEE
"-- SUBORDINATION," BELOW.

     Upon the sale or other disposition of the Capital Stock of a Subsidiary
Guarantor or the sale or disposition of all or substantially all the assets of a
Subsidiary Guarantor (in each case other than to Swift or an Affiliate of Swift)
permitted by the Indenture, such Subsidiary Guarantor will be released from all
its obligations under its Subsidiary Guaranty. FOR A MORE DETAILED DESCRIPTION
OF THESE OBLIGATIONS, SEE "-- CERTAIN COVENANTS -- LIMITATION ON ISSUANCE AND
SALE OF CAPITAL STOCK OF RESTRICTED SUBSIDIARIES," AND "-- CERTAIN COVENANTS
 -- LIMITATION ON ASSET SALES". In addition, any Subsidiary Guarantor that is
designated an Unrestricted Subsidiary in accordance with the terms of the
Indenture shall be released from and relieved of its obligations under its
Subsidiary Guaranty upon execution and delivery of a supplemental indenture
satisfactory to the Trustee.

                                      S-46
<PAGE>   47

     Each of Swift and any Subsidiary Guarantors will agree to contribute to any
other Subsidiary Guarantor that makes payments pursuant to its Subsidiary
Guaranty an amount equal to Swift's or such Subsidiary Guarantor's proportionate
share of such payment, based on the net worth of Swift or such Subsidiary
Guarantor relative to the aggregate net worth of Swift and the Subsidiary
Guarantors.

SUBORDINATION

     The Notes will be senior subordinated, unsecured obligations of Swift and:

     - the payment of principal, interest and any premium on the Notes will be
       subordinated in their right of payment to all existing and future Senior
       Indebtedness of Swift;

     - the Notes will rank equally in their right of payment with any future
       Pari Passu Indebtedness, and senior to all existing and future
       Subordinated Indebtedness of Swift; and

     - the Subsidiary Guaranty of any Subsidiary Guarantor will rank subordinate
       in right of payment to all existing and future Senior Indebtedness of
       such Subsidiary Guarantor, pari passu with any future Pari Passu
       Indebtedness of such Subsidiary Guarantor and senior to any future
       Subordinated Indebtedness of such Subsidiary Guarantor.

     After the closing of the offering of the Notes and the concurrent offering
of Swift common stock and the application of the estimated net proceeds of both
offerings, we will have $140.0 million of available borrowing capacity under our
credit facility and no outstanding Senior Indebtedness. Borrowings under our
credit facility constitute Senior Indebtedness. As of such date, we would have
had no outstanding Pari Passu outstanding Indebtedness and $115.0 million of
Subordinated Indebtedness.

     Although the Indenture contains limitations on the amount of additional
Indebtedness that Swift and its Restricted Subsidiaries may incur, the amounts
of such Indebtedness could be substantial and such Indebtedness may be Senior
Indebtedness or Pari Passu Indebtedness. In addition, the Subsidiary Guaranties
could be effectively subordinated to all the obligations of any Subsidiary
Guarantors under certain circumstances. The Notes and any Subsidiary Guaranties
will also be effectively subordinated to any secured debt of Swift and the
Subsidiary Guarantors that is not otherwise Senior Indebtedness. As of June 30,
1999, after giving pro forma effect to both the offering of the Notes and the
concurrent offering of common stock, the "offerings," and the application of the
net proceeds therefrom, there would have been no outstanding secured debt of
Swift that is not Senior Indebtedness. All existing and future liabilities of
Swift's Subsidiaries that are not Subsidiary Guarantors, including the claims of
trade creditors and preferred stockholders, if any, will be effectively senior
to the Notes. As of June 30, 1999, after giving effect to the offerings, the
total balance sheet liabilities of Swift's Subsidiaries (excluding intercompany
debts) was less than $1.0 million. Swift's Subsidiaries may have other
liabilities, including contingent liabilities, that may be significant. FOR A
MORE DETAILED DESCRIPTION, SEE "-- CERTAIN COVENANTS -- LIMITATION ON
INDEBTEDNESS," THE RISK FACTORS RELATING TO SUBORDINATION AND FRAUDULENT
CONVEYANCE, AND "DESCRIPTION OF EXISTING INDEBTEDNESS."

     We may not pay principal of, or premium, if any, or interest on, the Notes,
or make any deposit pursuant to the provisions described under "-- Defeasance",
and may not repurchase, redeem or otherwise retire any Notes (collectively, "pay
the Notes"), if:

     (a)      any principal, premium or interest or other amounts due in respect
              of any Senior Indebtedness of Swift is not paid within any
              applicable grace period (including at maturity); or

     (b)      any other default on Senior Indebtedness of Swift occurs and the
              maturity of such Senior Indebtedness is accelerated in accordance
              with its terms;

     unless, in either case,

           (1)      the default has been cured or waived and any such
                    acceleration has been rescinded, or

                                      S-47
<PAGE>   48

           (2)      such Senior Indebtedness has been paid in full in cash;

provided, however, that we may pay the Notes without regard to the foregoing if
we and the Trustee receive written notice approving such payment from the
Representative of such issue of Senior Indebtedness.

     During the continuance of any default (other than a default described in
clause (a) or (b) above) with respect to any Designated Senior Indebtedness
pursuant to which the maturity thereof may be accelerated immediately without
further notice (except such notice as may be required to effect such
acceleration), we may not pay the Notes for a period, a "Payment Blockage
Period," commencing upon the receipt by Swift and the Trustee of written notice,
a "Payment Blockage Notice," of such default from the Representative of the
holders of such Designated Senior Indebtedness specifying an election to effect
a Payment Blockage Period, and ending 179 days after receipt of such notice by
Swift and the Trustee, unless such Payment Blockage Period is earlier
terminated:

     (a)      by written notice to the Trustee and Swift from the Representative
              that gave such Payment Blockage Notice;

     (b)      because such default is no longer continuing; or

     (c)      because such Designated Senior Indebtedness has been repaid in
              full in cash.

Unless the holders of such Designated Senior Indebtedness or the Representative
of such holders have accelerated the maturity of such Designated Senior
Indebtedness and not rescinded such acceleration, we may, unless otherwise
prohibited as described in the first sentence of this paragraph, resume payments
on the Notes after the end of such Payment Blockage Period.

     No more than one Payment Blockage Notice with respect to all issues of
Designated Senior Indebtedness may be given in any consecutive 360-day period,
irrespective of the number of defaults with respect to one or more issues of
Designated Senior Indebtedness during such period.

     Upon any payment or distribution of the assets of Swift upon a total or
partial liquidation, dissolution or winding up of Swift or in a bankruptcy,
reorganization, insolvency, receivership or similar proceeding relating to Swift
or its Property:

     (a)      the holders of Senior Indebtedness of Swift will be entitled to
              receive payment in full in cash before the Holders of the Notes
              are entitled to receive any payment of principal of, or premium,
              if any, or interest on, the Notes, except that Holders of Notes
              may receive and retain shares of stock and any debt securities
              that are subordinated to all Senior Indebtedness of Swift to at
              least the same extent as the Notes; and

     (b)      until the Senior Indebtedness of Swift is paid in full in cash,
              any distribution made by or on behalf of Swift to which Holders of
              the Notes would be entitled but for the subordination provisions
              of the Indenture will be made to holders of the Senior
              Indebtedness of Swift. If a payment or distribution is made to
              Holders of Notes that, due to the subordination provisions, should
              not have been made to them, such Holders are required to hold it
              in trust for the holders of Senior Indebtedness and pay it over to
              them as their interests may appear.

     The Subsidiary Guaranty of any Subsidiary Guarantor will be subordinated to
Senior Indebtedness of such Subsidiary Guarantor to the same extent and in the
same manner as the Notes are subordinated to Senior Indebtedness of Swift.

     The Indenture will provide that the subordination provisions of the
Indenture applicable to the Notes and any Subsidiary Guarantee may not be
amended, waived or modified in a manner that would adversely affect the rights
of the holders of any Senior Indebtedness unless the holders of such Senior
Indebtedness consent in writing (in accordance with the provisions of such
Indebtedness) to such amendment, waiver or modification.

                                      S-48
<PAGE>   49

     Payment from the money or proceeds of U.S. Government Obligations held in
any defeasance trust pursuant to the provisions described under "-- Defeasance
and Covenant Defeasance" will not be subject to the subordination provisions
described above.

OPTIONAL REDEMPTION

     Except as set forth in the following paragraph, the Notes will not be
redeemable at the option of Swift prior to August 1, 2004. Starting on that
date, we may redeem all or any portion of the Notes upon not less than 30 nor
more than 60 days' prior notice, at the redemption prices set forth below, plus
accrued and unpaid interest, if any, to the redemption date subject to the right
of Holders of record on the relevant record date to receive interest due on the
relevant interest payment date. The following prices are for Notes redeemed
during the 12-month period commencing on August 1 of the years set forth below,
and are expressed as percentages of principal amount:

</TABLE>

     We may on any one or more occasions prior to August 1, 2002, redeem up to
33 1/3% of the aggregate principal amount of the Notes originally issued with
the net proceeds of one or more Equity Offerings of Swift at a redemption price
of 110.25% of the principal amount thereof, plus accrued and unpaid interest, if
any, to the date of redemption, subject to the right of Holders of record on the
relevant record date to receive interest due on the relevant interest payment
date, provided that at least 66 2/3% of the aggregate principal amount of the
Notes originally issued remains outstanding after the occurrence of such
redemption. Any such redemption shall occur not later than 90 days after the
date of the closing of any such Equity Offering upon not less than 30 or more
than 60 days' prior notice. The redemption shall be made in accordance with
procedures set forth in the Indenture.

     If less than all the Notes are to be redeemed at any time, selection of
Notes for redemption will be made by the Trustee 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 shall deem fair and appropriate.

SINKING FUND

     There will be no mandatory sinking fund payments for the Notes.

REPURCHASE AT THE OPTION OF HOLDERS UPON A CHANGE OF CONTROL

     Upon the occurrence of a Change of Control, each Holder of Notes shall have
the right to require us to repurchase all or any part (equal to $1,000 in
principal amount or an integral multiple thereof) of such Holder's Notes
pursuant to the offer described below, "Change of Control Offer", at a purchase
price in cash, a "Change of Control Payment," equal to 101% of the principal
amount of the Notes repurchased, plus accrued and unpaid interest, if any, to
the date of purchase, subject to the right of Holders of record on the relevant
record date to receive interest due on the relevant interest payment date.

     Within 30 days following any Change of Control, we shall:

     (a)      cause a notice of the Change of Control Offer to be sent at least
              once to the Dow Jones News Service or similar business news
              service in the United States; and

     (b)      send, by first-class mail, with a copy to the Trustee, to each
              Holder of Notes, at such Holder's address appearing in the
              Security Register, a notice stating, among other things:

           (1)      that a Change of Control has occurred and a Change of
                    Control Offer is being made pursuant to the Indenture and
                    that all Notes, or portions thereof, properly tendered will
                    be accepted for payment,

           (2)      the Change of Control Purchase Price and the purchase date,
                    which shall be, subject to any contrary requirements of
                    applicable law, a business day, a "Change of Control Payment
                    Date," no earlier than 30 days nor later than 60 days from
                    the date we mail such notice,

           (3)      that any Note, or portion thereof, accepted for payment, and
                    duly paid on the Change of Control Payment Date, pursuant to
                    the Change of Control Offer shall cease to accrue interest
                    on the Change of Control Payment Date,

           (4)      that any Notes, or portions thereof, not properly tendered
                    will continue to accrue interest,

           (5)      a description of the transaction or transactions
                    constituting the Change of Control,

           (6)      the procedures that the Holders of the Notes must follow in
                    order to tender their Notes, or portions thereof, for
                    payment and the procedures that Holders of Notes must follow
                    in order to withdraw an election to tender Notes, or
                    portions thereof, for payment, and

           (7)      all other instructions and materials necessary to enable
                    Holders to tender Notes pursuant to the Change of Control
                    Offer.

     We will comply, to the extent applicable, with the requirements of Section
14(e) under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws and regulations are applicable in connection
with the purchase of Notes pursuant to a Change of Control Offer. To the extent
that the provisions of any securities laws or regulations conflict with the
provisions relating to the Change of Control Offer, we will comply with the
applicable securities laws and regulations and will not be deemed to have
breached our obligations described above by virtue of such compliance.

     If a Change of Control were to occur, Swift and any Subsidiary Guarantors
may not have sufficient financial resources, or may not be able to arrange
financing, to pay the purchase price for all Notes tendered by the Holders
thereof. In addition, as of the Issue Date, our existing credit facility does,
and any future Bank Credit Facilities or other agreements relating to
indebtedness, including Senior Indebtedness or Pari Passu Indebtedness, to which
Swift or any Subsidiary Guarantor becomes a party may, contain restrictions on
the purchase of Notes and prohibitions on certain events that would constitute a
Change of Control or require such indebtedness to be repurchased upon a Change
of Control. If a Change of Control occurs at a time when Swift and the
Subsidiary Guarantors are unable to purchase the Notes (due to insufficient
financial resources, contractual prohibition or otherwise), such failure to
purchase tendered Notes would constitute an Event of Default under the
Indenture, which would, in turn, constitute a default under our credit facility
and may constitute a default under the terms of any other Bank Credit Facility
or other Indebtedness of Swift or any Subsidiary Guarantors then outstanding. In
such circumstances, the subordination provisions in the Indenture would likely
prohibit the Change of Control payments to Holders of Notes. The provisions
under the Indenture related to Swift's obligation to make an offer to repurchase
the Notes as a result of a Change of Control may be waived or modified, at any
time prior to the occurrence of such Change of Control, with the written consent
of the Holders of a majority in principal amount of the Notes. FOR A DETAILED
DESCRIPTION, SEE "-- SUBORDINATION," ABOVE.

     We will 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

                                      S-50
<PAGE>   51

requirements set forth in the Indenture applicable to a Change of Control Offer
made by us and purchases all Notes validly tendered and not withdrawn under such
Change of Control Offer.

     A "Change of Control" shall be deemed to occur if:

     (a)      any "person" or "group" (within the meaning of Section 13(d)(3)
              and 14(d)(2) of the Exchange Act or any successor provision to
              either of the foregoing, including any group acting for the
              purpose of acquiring, holding or disposing of securities within
              the meaning of Rule 13d-5(b)(1) under the Exchange Act) becomes
              the "beneficial owner" (as defined in Rules 13d-3 and 13d-5 under
              the Exchange Act, except that a Person will be deemed to have
              "beneficial ownership" of all shares that any such Person has the
              right to acquire, whether such right is exercisable immediately or
              only after the passage of time) of 40 percent or more of the total
              voting power of all classes of the Voting Stock of Swift;

     (b)      the sale, lease, assignment, conveyance, transfer or other
              disposition, directly or indirectly, of all or substantially all
              the assets of Swift and the Restricted Subsidiaries taken as a
              whole (other than a disposition of such assets as an entirety or
              virtually as an entirety to any Wholly Owned Subsidiary) shall
              have occurred;

     (c)      the shareholders of Swift shall have approved any plan of
              liquidation or dissolution of Swift;

     (d)      Swift consolidates with or merges into another Person or any
              Person consolidates with or merges into us in any such event
              pursuant to a transaction in which the outstanding Voting Stock of
              Swift is reclassified into or exchanged for cash, securities or
              other property, other than any such transaction where the
              outstanding Voting Stock of Swift is reclassified into or
              exchanged for Voting Stock of the surviving corporation and the
              holders of the Voting Stock of Swift immediately prior to such
              transaction own, directly or indirectly, not less than a majority
              of the Voting Stock of the surviving corporation immediately after
              such transaction in substantially the same proportion as before
              the transaction; or

     (e)      during any period of two consecutive years, individuals who at the
              beginning of such period constituted Swift's Board of Directors
              (together with any new directors whose election or appointment by
              such Board or whose nomination for election by the shareholders of
              Swift was approved by a vote of a majority of the directors then
              still in office who were either directors at the beginning of such
              period or whose election or nomination for election was previously
              approved by such a vote) cease for any reason to constitute a
              majority of Swift's Board of Directors then in office.

     The Change of Control repurchase feature is a result of negotiations
between Swift and the Underwriters. We have no present intention to engage in a
transaction involving a Change of Control, although it is possible that we would
decide to do so in the future. Subject to certain covenants described below, we
could, in the future, enter into certain transactions, including acquisitions,
refinancings or other recapitalizations, that would not constitute a Change of
Control under the Indenture, but that could increase the amount of indebtedness
outstanding at such time or otherwise affect Swift's capital structure or credit
ratings.

     The definition of Change of Control includes a phrase relating to the sale,
lease, conveyance or transfer of "all or substantially all" Swift's assets. The
Indenture will be governed by New York law, and there is no established
quantitative definition under New York law of "substantially all" the assets of
a corporation. Accordingly, if Swift or any Restricted Subsidiary were to engage
in a transaction in which they disposed of less than all the assets of Swift and
its Restricted Subsidiaries taken as a whole, a question of interpretation could
arise as to whether such disposition was of "substantially all" its assets and
whether we were required to make a Change of Control Offer.

     Except as described above with respect to a Change of Control, the
Indenture does not contain any other provisions that permit the Holders of the
Notes to require that we repurchase or redeem the Notes in the event of a
takeover, recapitalization or similar restructuring.

CERTAIN COVENANTS

  Limitation on Indebtedness

     The Indenture provides that we will not, and will not permit any of our
Restricted Subsidiaries to, directly or indirectly, Incur any Indebtedness
unless, after giving pro forma effect to the Incurrence of such Indebtedness and
the receipt and application of the proceeds thereof, no Default or Event of
Default would occur as a consequence of, or be continuing following, such
Incurrence and application and either:

     (a)      after giving pro forma effect to such Incurrence and application,
              the Consolidated Interest Coverage Ratio would exceed 2.5 to 1.0;
              or

     (b)      such Indebtedness is Permitted Indebtedness.

     "Permitted Indebtedness" means any and all of the following:

              GREATER OF:

           (1)      $250.0 million, which amount shall be permanently reduced by
                    the amount of Net Available Cash used to permanently repay
                    Indebtedness under Bank Credit Facilities and not
                    subsequently reinvested in Additional Assets or used to
                    permanently reduce other Indebtedness pursuant to the
                    provisions of the Indenture described under "-- Limitation
                    on Asset Sales", and

           (2)      an amount equal to the sum of:

              Subsidiary and Indebtedness of a Restricted Subsidiary owing to
              and held by Swift or any Wholly Owned Subsidiary; provided,
              however, that any subsequent issue or transfer of Capital Stock or
              other event that results in any such Wholly Owned Subsidiary
              ceasing to be a Wholly Owned Subsidiary or any subsequent transfer
              of any such Indebtedness (except to Swift or a Wholly Owned
              Subsidiary) shall be deemed, in each case, to constitute the
              Incurrence of such Indebtedness by the issuer thereof;

     (d)      Indebtedness in respect of bid, performance, reimbursement or
              surety obligations issued by or for the account of Swift or any
              Restricted Subsidiary in the ordinary course of business,
              including guaranties and letters of credit functioning as or
              supporting such bid, performance, reimbursement or surety

              clause (a) of "-- Limitation of Indebtedness"), provided that the
              aggregate principal amount of all Indebtedness Incurred pursuant
              to this clause (i), together with all Indebtedness Incurred
              pursuant to clause (j) of this paragraph in respect of
              Indebtedness previously Incurred pursuant to this clause (i), at
              any one time outstanding does not exceed $30.0 million;

              price adjustments, indemnities or Guarantees of the same or
              similar matters in connection with the acquisition or disposition
              of Property.

  Limitation on Liens

     The Indenture provides that we will not, and will not permit any Restricted
Subsidiary to, directly or indirectly, enter into, create, Incur, assume or
suffer to exist any Lien on or with respect to any Property of Swift or such
Restricted Subsidiary, whether owned on the Issue Date or acquired after the
Issue Date, or any interest therein or any income or profits therefrom, unless
the Notes or any Subsidiary Guaranty of such Restricted Subsidiary are secured
equally and ratably with, or prior to, any and all other obligations secured by
such Lien, except that Swift and its Restricted Subsidiaries may enter into,
create, Incur, assume or suffer to exist Liens securing Senior Indebtedness and
Permitted Liens.

  Limitation on Restricted Payments

     We will not, and will not permit any of our Restricted Subsidiaries to,
directly or indirectly, make any Restricted Payment if, at the time of and after
giving effect to the proposed Restricted Payment:

     (a)      any Default or Event of Default would have occurred and be
              continuing;

     (b)      we could not Incur at least $1.00 of additional Indebtedness
              pursuant to clause (a) of the first paragraph under "-- Limitation
              on Indebtedness"; or

     (c)      the aggregate amount expended or declared for all Restricted
              Payments from the Issue Date WOULD EXCEED THE SUM OF (without
              duplication):

           (1)      50% of the aggregate Consolidated Net Income of Swift
                    accrued during the period (treated as one accounting period)
                    commencing on the first day of the fiscal quarter during
                    which the Issue Date occurs, and ending on the last day of
                    the fiscal quarter immediately preceding the date of such
                    proposed Restricted Payment (or, if such aggregate

                    loss), AND

                    Swift) on or after the Issue Date, AND

           (4)      the aggregate net cash proceeds received by us from the
                    issuance or sale (other than to any Subsidiary of Swift or
                    an employee stock ownership plan or trust established by us
                    or any such Subsidiary for the benefit of their employees)
                    on or after the Issue Date of convertible Indebtedness that
                    has been converted into or exchanged for Capital Stock
                    (other than Disqualified Stock) of Swift, together with the
                    aggregate cash received by us at the time of such conversion
                    or exchange or received by us from any conversion or
                    exchange of convertible Senior Indebtedness or convertible

                            Subsidiary of Swift or an employee stock ownership
                            plan or trust established by us or any such
                            Subsidiary for the benefit of their employees, and

                   (B)      the aggregate amount of any cash or other Property
                            distributed by us or any Restricted Subsidiary upon
                            any such conversion or exchange, AND

           (5)      to the extent not otherwise included in Swift's Consolidated
                    Net Income, an amount equal to the net reduction in
                    Investments made by Swift and its Restricted Subsidiaries
                    subsequent to the Issue Date in any Person resulting from:

                   (A)      payments of interest on debt, dividends, repayments
                            of loans or advances or other transfers or

                            Restricted Subsidiary from any Person other than
                            Swift or a Restricted Subsidiary, and in an amount
                            not to exceed the book value of such Investments
                            previously made in such Person that were treated as
                            Restricted Payments, or

                   (B)      the designation of any Unrestricted Subsidiary as a
                            Restricted Subsidiary, and in an amount not to
                            exceed the lesser of:

                           (x)      the book value of all Investments previously
                                    made in such Unrestricted Subsidiary that
                                    were treated as Restricted Payments, and

                           (y)      the Fair Market Value of Swift's and its

           (6)      $15.0 million.

     The limitations set forth in the preceding paragraph will not prevent us or
any Restricted Subsidiary from making the following Restricted Payments so long
as, at the time thereof, no Default or Event of Default shall have occurred and
be continuing:

     (a)      the payment of any dividend on Capital Stock of Swift or any
              Restricted Subsidiary within 60 days after the declaration
              thereof, if at such declaration date such dividend could have been
              paid in compliance with the preceding paragraph;

     (b)      the repurchase, redemption or other acquisition or retirement for
              value of any Capital Stock of Swift or any of its Subsidiaries
              pursuant to the terms of agreements (including employment
              agreements) or plans (including by employee stock ownership plans
              but excluding other plans to purchase such Capital Stock in open
              market transactions, together with, in the case of employee stock
              ownership plans, loans to or Investments therein in an amount
              sufficient to fund such repurchase, redemption or other
              acquisition or retirement by such plan) approved by Swift's Board
              of Directors, including any such repurchase, redemption,
              acquisition or retirement of shares of such Capital Stock that is
              deemed to occur upon the exercise of stock options or similar
              rights if such shares represent all or a portion of the exercise
              price or are surrendered in connection with satisfying Federal
              income tax obligations; provided, however, that the aggregate
              amount of such repurchase, redemptions, acquisitions and
              retirements shall not exceed the sum of:

           (1)      $2.0 million in any twelve-month period, and

           (2)      the aggregate net proceeds, if any, received by us during
                    such twelve-month period from any issuance of such Capital

              value of any Capital Stock of Swift or any Restricted Subsidiary,
              in exchange for, or out of the aggregate net cash proceeds of, a

              Subsidiary of Swift or an employee stock ownership plan or trust
              established by us or any of its Subsidiaries, for the benefit of
              their employees) of Capital Stock of Swift (other than
              Disqualified Stock);

     (d)      the purchase, redemption, legal defeasance, acquisition or
              retirement for value of any Subordinated Indebtedness in exchange
              for, or out of the proceeds of the substantially concurrent sale
              of, Capital Stock of Swift (other than Disqualified Stock and
              other than Capital Stock issued or sold to a Subsidiary of Swift
              or an employee stock ownership plan or trust established by us or
              any such Subsidiary for the benefit of their employees);

              Directors (or by a duly authorized officer), the net cash proceeds
              of which are used solely:

           (1)      to purchase common stock of Swift in connection with a
                    restricted stock or employee stock purchase plan, or to
                    exercise stock options received pursuant to an employee or
                    director stock option plan or other incentive plan, in a
                    principal amount not to exceed the purchase price of such

Limitation on Issuance and Sale of Capital Stock of Restricted Subsidiaries

     We will not:

     (a)      permit any Restricted Subsidiary to sell or otherwise issue any
              Capital Stock other than to Swift or one of its Wholly Owned
              Subsidiaries; or

     (b)      sell, pledge, hypothecate or otherwise dispose of any shares of
              Capital Stock of any Restricted Subsidiary, or permit any
              Restricted Subsidiary to do so, except, in each case, for:

           (1)      directors' qualifying shares,

           (2)      the Capital Stock of a Restricted Subsidiary owned by a
                    Person at the time such Restricted Subsidiary became a
                    Restricted Subsidiary or acquired by such Person in
                    connection with the formation of such Restricted Subsidiary,
                    or transfers thereof, or

           (3)      a sale of all the Capital Stock of a Restricted Subsidiary
                    owned by Swift or its Subsidiaries effected in accordance
                    with the provisions of the Indenture described under
                    "-- Limitation on Asset Sales."

     In the event of the consummation of a sale of all the Capital Stock of a
Restricted Subsidiary pursuant to the foregoing clause (3) and the execution and
delivery of a supplemental indenture in form satisfactory to the Trustee, any
such Restricted Subsidiary that is also a Subsidiary Guarantor shall be released
from all its obligations under its Subsidiary Guaranty.

  Limitation on Asset Sales

     The Indenture provides that we will not, and will not permit any Restricted
Subsidiary to, consummate any Asset Sale unless:

     (a)      Swift or such Restricted Subsidiary, as the case may be, receives
              consideration at the time of such Asset Sale at least equal to the
              Fair Market Value of the Property subject to such Asset Sale; and

     (b)      all of the consideration paid to Swift or such Restricted
              Subsidiary in connection with such Asset Sale is in the form of
              cash, cash equivalents, Liquid Securities, Exchanged Properties or
              the assumption by the purchaser of liabilities of Swift (other
              than liabilities of Swift that are by their terms subordinated to
              the Notes) or liabilities of any Subsidiary Guarantor that made
              such Asset Sale (other than liabilities of a Subsidiary Guarantor
              that are by their terms subordinated to such Subsidiary
              Guarantor's Subsidiary Guaranty), in each case as a result of
              which Swift and its remaining Restricted Subsidiaries are no
              longer liable for such liabilities, defined as "Permitted
              Consideration"; provided, however, that Swift and its Restricted
              Subsidiaries shall be permitted to receive Property other than
              Permitted Consideration, so long as the aggregate Fair Market
              Value of all such Property other than Permitted Consideration
              received from Asset Sales and held by Swift or any Restricted
              Subsidiary at any one time shall not exceed 10.0% of Adjusted
              Consolidated Net Tangible Assets.

     The Net Available Cash from Asset Sales by us or a Restricted Subsidiary
may be applied by us or such Restricted Subsidiary, to the extent we or such
Restricted Subsidiary elects (or is required by the terms of any Senior
Indebtedness of Swift or a Subsidiary Guarantor), to:

     (a)      prepay, repay or purchase Senior Indebtedness of Swift or a
              Subsidiary Guarantor (in each case excluding Indebtedness owed to
              us or an Affiliate of Swift);

     (b)      to reinvest in Additional Assets (including by means of an
              Investment in Additional Assets by a Restricted Subsidiary with
              Net Available Cash received by us or another Restricted
              Subsidiary); or
                                      S-56
<PAGE>   57

     (c)      purchase Notes or purchase both Notes and one or more series or
              issues of other Pari Passu Indebtedness on a pro rata basis
              (excluding Notes and Pari Passu Indebtedness owed to us or any of
              our Affiliates).

     Any Net Available Cash from an Asset Sale not applied in accordance with
the preceding paragraph within 365 days from the date of such Asset Sale shall
constitute "Excess Proceeds." When the aggregate amount of Excess Proceeds
exceeds $10.0 million, we will be required to make an offer, a "Prepayment
Offer," to purchase Notes having an aggregate principal amount equal to the
aggregate amount of Excess Proceeds, at a purchase price equal to 100% of the
principal amount of such Notes plus accrued and unpaid interest, if any, to the
Purchase Date (as defined) in accordance with the procedures (including
proration in the event of oversubscription) set forth in the Indenture, but, if
the terms of any Pari Passu Indebtedness require that a Pari Passu Offer be made
contemporaneously with the Prepayment Offer, then the Excess Proceeds shall be
prorated between the Prepayment Offer and such Pari Passu Offer in accordance
with the aggregate outstanding principal amounts of the Notes and such Pari
Passu Indebtedness, and the aggregate principal amount of Notes for which the
Prepayment Offer is made shall be reduced accordingly. If the aggregate
principal amount of Notes tendered by Holders thereof exceeds the amount of
available Excess Proceeds, then such Excess Proceeds will be allocated pro rata
according to the principal amount of the Notes tendered and the Trustee will
select the Notes to be purchased in accordance with the Indenture. To the extent
that any portion of the amount of Excess Proceeds remains after compliance with
the second sentence of this paragraph, and provided that all Holders of Notes
have been given the opportunity to tender their Notes for purchase as described
in the following paragraph in accordance with the Indenture, Swift and its
Restricted Subsidiaries may use such remaining amount for purposes permitted by
the Indenture, and the amount of Excess Proceeds will be reset to zero.

     Within 30 days after the 365th day following the date of an Asset Sale,
Swift shall, if it is obligated to make an offer to purchase the Notes pursuant
to the preceding paragraph, send a written Prepayment Offer notice, the
"Prepayment Offer Notice," by first-class mail, to the Holders of the Notes,
accompanied by such information regarding Swift and its Subsidiaries as we
believe will enable such Holders of the Notes to make an informed decision with
respect to the Prepayment Offer. The Prepayment Offer Notice will state, among
other things:

     (a)      that we are offering to purchase Notes pursuant to the provisions
              of the Indenture;

     (b)      that any Note (or any portion thereof) accepted for payment (and
              duly paid on the Purchase Date) pursuant to the Prepayment Offer
              shall cease to accrue interest on the Purchase Date;

     (c)      that any Notes (or portions thereof) not properly tendered will
              continue to accrue interest;

     (d)      the purchase price and purchase date, the "Purchase Date," which
              shall be, subject to any contrary requirements of applicable law,
              no less than 30 days nor more than 60 days after the date the
              Prepayment Offer Notice is mailed;

     (e)      the aggregate principal amount of Notes to be purchased;

     (f)      a description of the procedure that Holders of Notes must follow
              in order to tender their Notes for payment; and

     (g)      all other instructions and materials necessary to enable Holders
              to tender Notes pursuant to the Prepayment Offer.

     We will comply, to the extent applicable, with the requirements of Section
14(e) under the Exchange Act and any other securities laws or regulations
thereunder to the extent such laws and regulations are applicable in connection
with the purchase of Notes as described above. To the extent that the provisions
of any securities laws or regulations conflict with the provisions relating to
the Prepayment Offer, we will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations described
above by virtue thereof.

  Incurrence of Layered Indebtedness

     The Indenture provides that:

     (a)      we will not Incur any Indebtedness that is subordinated or junior
              in right of payment to any Senior Indebtedness of Swift unless
              such Indebtedness constitutes Indebtedness that is junior to, or
              pari passu with, the Notes in right of payment; and

     (b)      no Subsidiary Guarantor will Incur any Indebtedness that is
              subordinated or junior in right of payment to any Senior
              Indebtedness of such Subsidiary Guarantor unless such Indebtedness
              constitutes Indebtedness that in right of payment is junior to, or
              pari passu with, such Subsidiary Guarantor's Subsidiary Guaranty.

  Limitation on Transactions with Affiliates

     The Indenture provides that we will not, and will not permit any of our
Restricted Subsidiaries to, directly or indirectly, conduct any business or
enter into any transaction or series of transactions (including the sale,
transfer, disposition, purchase, exchange or lease of Property, the making of
any Investment, the giving of any Guarantee or the rendering of any service)
with or for the benefit of any Affiliate of Swift (other than Swift or a Wholly
Owned Subsidiary), unless:

     (a)      such transaction is set forth in writing;

     (b)      such transaction or series of transactions is on terms no less
              favorable to us or such Restricted Subsidiary than those that
              could be obtained in a comparable arm's-length transaction with a
              Person that is not an Affiliate of Swift or such Restricted
              Subsidiary; and

     (c)      with respect to a transaction or series of transactions involving
              aggregate payments by or to us or such Restricted Subsidiary
              having a Fair Market Value equal to or in excess of:

           (1)      $1.0 million but less than $5.0 million, an officer of Swift
                    certifies that such transaction or series of transactions
                    complies with clause (b) of this paragraph, as evidenced by
                    an Officer's Certificate delivered to the Trustee,

           (2)      $5.0 million but less than $20.0 million, the Board of
                    Directors of Swift (including a majority of the
                    disinterested members of such Board of Directors) approves
                    such transaction or series of transactions and certifies
                    that such transaction or series of transactions complies
                    with clause (b) of this paragraph, as evidenced by a
                    certified resolution delivered to the Trustee, or

                            firm, in either case specializing or having a
                            specialty in the type and subject matter of the
                            transaction (or series of transactions) at issue, a
                            written opinion that such transaction (or series of
                            transactions) is fair, from a financial point of
                            view, to us or such Restricted Subsidiary, and

                   (B)      such Board of Directors (including a majority of the
                            disinterested members of the Board of Directors of
                            Swift) approves such transaction or series of

                            series of transactions complies with clause (b) of

                    common stock of Swift in connection with a restricted stock
                    or employee stock purchase plan, or to exercise stock

  Limitation on Restrictions on Distributions from Restricted Subsidiaries

     The Indenture provides that we will not, and will not permit any of our
Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any consensual encumbrance or restriction on
the legal right of any Restricted Subsidiary to:

     (a)      pay dividends, in cash or otherwise, or make any other
              distributions on or in respect of its Capital Stock, or pay any
              Indebtedness or other obligation owed, to us or any other
              Restricted Subsidiary;

     (b)      make loans or advances to Swift or any other Restricted

     Such limitation will not apply:

           (1)      with respect to clauses (a), (b) and (c), to encumbrances
                    and restrictions:

                   (A)      in agreements and instruments as in effect on the

                   (B)      relating to Indebtedness of a Restricted Subsidiary
                            and existing at the time it became a Restricted
                            Subsidiary if such encumbrance or restriction was
                            not created in anticipation of or in connection with
                            the transactions pursuant to which such Restricted
                            Subsidiary became a Restricted Subsidiary, or

                   (C)      that result from the renewal, refinancing, extension

                            restriction is not materially less favorable to the
                            Holders of Notes than those under or pursuant to the
                            agreement so renewed, refinanced, extended or
                            amended, and,

           (2)      with respect to clause (c) only, to:

                   (A)      restrictions pursuant to Liens permitted to be in
                            effect without also securing the Notes under the

                            "Limitation on Liens" that limit the right of the
                            debtor to dispose of the Property subject to such
                            Lien,

                   (B)      any encumbrance or restriction applicable to
                            Property at the time it is acquired by us or a
                            Restricted Subsidiary, so long as such encumbrance
                            or restriction relates solely to the Property so
                            acquired and was not created in anticipation of or
                            in connection with such acquisition,

                   (C)      customary provisions restricting subletting or
                            assignment of leases and customary provisions in
                            other agreements that restrict assignment of such
                            agreements or rights thereunder, and

                   (D)      customary restrictions contained in asset sale
                            agreements limiting the transfer of such assets
                            pending the closing of such sale.

  Future Subsidiary Guarantors

     We shall cause each Restricted Subsidiary that:

     (a)      incurs Indebtedness or issues Preferred Stock following the Issue
              Date; or

     (b)      has Indebtedness or Preferred Stock outstanding on the date on
              which such Restricted Subsidiary becomes a Restricted Subsidiary,

to execute and deliver to the Trustee a Subsidiary Guaranty at the time such
Restricted Subsidiary Incurs such Indebtedness or becomes a Restricted
Subsidiary; provided, however, that such Restricted Subsidiary shall not be
required to deliver a Subsidiary Guaranty if the aggregate amount of such
Indebtedness or Preferred Stock, together with all other Indebtedness and
Preferred Stock then outstanding among Restricted Subsidiaries that are not
Subsidiary Guarantors, is less than $10.0 million.

  Restricted and Unrestricted Subsidiaries

     Unless defined or designated as an Unrestricted Subsidiary, any Person that
becomes a Subsidiary of Swift or any of its Restricted Subsidiaries shall be
classified as a Restricted Subsidiary subject to the

                                      S-60
<PAGE>   61

provisions of the next paragraph. We may designate a Subsidiary (including a
newly formed or newly acquired Subsidiary) of Swift or any of its Restricted
Subsidiaries as an Unrestricted Subsidiary if:

     (a)      such Subsidiary does not at such time own any Capital Stock or
              Indebtedness of, or own or hold any Lien on any Property of, Swift
              or any other Restricted Subsidiary;

     (b)      such Subsidiary does not at such time have any Indebtedness or
              other obligations that, if in default, would result (with the
              passage of time or notice or otherwise) in a default on any
              Indebtedness of Swift or any Restricted Subsidiary; and

     (c)      (1)      such designation is effective immediately upon such
                       Subsidiary becoming a Subsidiary of Swift or of a
                       Restricted Subsidiary,

           (2)      the Subsidiary to be so designated has total assets of
                    $1,000 or less, or

           (3)      if such Subsidiary has assets greater than $1,000, then such
                    redesignation as an Unrestricted Subsidiary is deemed to
                    constitute a Restricted Payment in an amount equal to the
                    Fair Market Value of Swift's direct and indirect ownership
                    interest in such Subsidiary, and such Restricted Payment
                    would be permitted to be made at the time of such
                    designation under "-- Limitation on Restricted Payments."
                    Except as provided in the immediately preceding sentence, no
                    Restricted Subsidiary may be redesignated as an Unrestricted
                    Subsidiary. The designation of an Unrestricted Subsidiary or
                    removal of such designation shall be made by the Board of
                    Directors of Swift or a committee thereof pursuant to a
                    certified resolution delivered to the Trustee and shall be
                    effective as of the date specified in the applicable
                    certified resolution, which shall not be prior to the date
                    such certified resolution is delivered to the Trustees.

     We will not, and will not permit any of our Restricted Subsidiaries to,
take any action or enter into any transaction or series of transactions that
would result in a Person becoming a Restricted Subsidiary (whether through an
acquisition or otherwise) unless, after giving effect to such action,
transaction or series of transactions, on a pro forma basis:

     (a)      we could Incur at least $1.00 of additional Indebtedness pursuant
              to clause (a) of the first paragraph under "-- Limitation on
              Indebtedness"; and

     (b)      no Default or Event of Default would occur or be continuing.

MERGER, CONSOLIDATION AND SALE OF SUBSTANTIALLY ALL ASSETS

     We shall not consolidate with or merge with or into any Person, or convey,
transfer or lease, in one transaction or series of transactions, all or
substantially all our Property, unless:

     (a)      the resulting, surviving or transferee person, a "Successor
              Company", shall be a Person organized or existing under the laws
              of the United States of America, any State thereof or the District
              of Columbia and the Successor Company (if not Swift) shall
              expressly assume, by a supplemental indenture, executed and
              delivered to the Trustee, in form satisfactory to the Trustee, all
              the obligations of Swift under the Notes and the Indenture;

     (b)      in the case of a conveyance, transfer or lease of all or
              substantially all of Swift's Property, such Property shall have
              been so conveyed, transferred or leased as an entirety or
              virtually as an entirety to one Person;

     (c)      immediately after giving effect to such transaction (and treating,
              for purposes of this clause (c) and clauses (d) and (e) below, any
              Indebtedness that becomes or is anticipated to become an
              obligation of the Successor Company or any Restricted Subsidiary
              as a result of such transaction as having been Incurred by such
              Successor Company or such Restricted

                                      S-61
<PAGE>   62

              Subsidiary at the time of such transaction), no Default or Event
              of Default shall have occurred and be continuing;

     (d)      immediately after giving effect to such transaction, the Successor
              Company would be able to Incur an additional $1.00 of Indebtedness
              pursuant to clause (a) of the first paragraph under "-- Limitation
              on Indebtedness;"

     (e)      immediately after giving effect to such transaction, the Successor
              Company shall have Consolidated Net Worth in an amount that is not
              less than the Consolidated Net Worth of Swift immediately prior to
              such transaction; and

     (f)      we shall have delivered to the Trustee an Officer's Certificate,
              stating that such consolidation, merger or transfer and such
              supplemental indenture (if any) comply with the Indenture.

The Successor Company shall be the successor to Swift and shall succeed to, and
be substituted for, and may exercise every right and power of Swift under the
Indenture, but the predecessor Company in the case of a conveyance, transfer or
lease shall not be released from the obligation to pay the principal of and
interest on the Notes.

     Notwithstanding that we may not be subject to the reporting requirements of
Section 13 or 15(d) of the Exchange Act, we shall file with the Commission and

              acquisition from third parties of Capital Stock of such Person) as
              a result of which such other Person becomes a Restricted
              Subsidiary in compliance with the provisions of the Indenture
              described under "-- Certain Covenants  -- Restricted and
              Unrestricted Subsidiaries";

of the date of determination, the remainder of:

     (a)      THE SUM OF:

           (1)      discounted future net revenues from proved oil and gas
                    reserves of Swift and its Restricted Subsidiaries calculated
                    in accordance with SEC guidelines before any state, federal
                    or foreign income taxes, as estimated by Swift and confirmed
                    by a
                                      S-62
<PAGE>   63

                    nationally recognized firm of independent petroleum
                    engineers in a reserve report prepared as of the end of our
                    most recently completed fiscal year for which audited
                    financial statements are available, as increased by, as of
                    the date of determination, the estimated discounted future
                    net revenues from:

                   (A)      estimated proved oil and gas reserves acquired since
                            such year-end, which reserves were not reflected in
                            such year-end reserve report, and

                   (B)      estimated oil and gas reserves attributable to
                            upward revisions of estimates of proved oil and gas
                            reserves since such year-end due to exploration,
                            development or exploitation activities, in each case
                            calculated in accordance with SEC guidelines
                            (utilizing the prices utilized in such year-end
                            reserve report),

                           and decreased by, as of the date of determination,
                           the estimated discounted future net revenues from:

                   (C)      estimated proved oil and gas reserves produced or
                            disposed of since such year-end, and

                   (D)      estimated oil and gas reserves attributable to
                            downward revisions of estimates of proved oil and
                            gas reserves since such year-end due to changes in
                            geological conditions or other factors that would,
                            in accordance with standard industry practice, cause
                            such revisions, in each case calculated in
                            accordance with SEC guidelines (utilizing the prices
                            utilized in such year-end reserve report).

                   provided that, in the case of each of the determinations made
                   pursuant to clauses (A) through (D), such increases and
                   decreases shall be as estimated by our petroleum engineers,
                   unless there is a Material Change as a result of such
                   acquisitions, dispositions or revisions, in which event the
                   discounted future net revenues utilized for purposes of this
                   clause (a)(1) shall be confirmed in writing by a nationally
                   recognized firm of independent petroleum engineers, AND

           (2)      the capitalized costs that are attributable to oil and gas
                    properties of Swift and its Restricted Subsidiaries to which
                    no proved oil and gas reserves are attributable, based on
                    our books and records as of a date no earlier than the date
                    of our latest annual or quarterly financial statements, AND

           (3)      our Net Working Capital on a date no earlier than the date
                    of our latest annual or quarterly financial statements, AND

           (4)      the greater of the net book value or the appraised value as
                    estimated by independent appraisers of other tangible assets
                    (including, without duplication, Investments in
                    unconsolidated Restricted Subsidiaries) of Swift and its
                    Restricted Subsidiaries, as of a date no earlier than the
                    date of our latest audited financial statements. For these
                    purposes, net book value shall be determined as of a date no
                    earlier than the date of our latest annual or quarterly
                    financial statements, and on a date no earlier than the date
                    of our latest annual or quarterly financial statements;

     (b)      MINUS THE SUM OF:

           (1)      minority interests, AND

           (2)      any net gas balancing liabilities of Swift and its
                    Restricted Subsidiaries reflected in its latest audited
                    financial statements, AND

           (3)      to the extent included in (a)(1) above, the discounted
                    future net revenues, calculated in accordance with SEC
                    guidelines (utilizing the prices utilized in our

                                      S-63
<PAGE>   64

                    year-end reserve report), attributable to reserves that are
                    required to be delivered to third parties to fully satisfy
                    the obligations of Swift and its Restricted Subsidiaries
                    with respect to Volumetric Production Payments (determined,
                    if applicable, using the schedules specified with respect
                    thereto), AND

           (4)      the discounted future net revenues, calculated in accordance
                    with SEC guidelines, attributable to reserves subject to
                    Dollar-Denominated Production Payments that, based on the
                    estimates of production and price assumptions included in
                    determining the discounted future net revenues specified in
                    (a)(1) above, would be necessary to fully satisfy the
                    payment obligations of Swift and its Restricted Subsidiaries
                    with respect to Dollar-Denominated Production Payments
                    (determined, if applicable, using the schedules specified
                    with respect thereto).

     If we change our method of accounting from the full cost method to the
     successful efforts method or a similar method of accounting, "Adjusted
     Consolidated Net Tangible Assets" will continue to be calculated as if we
     were still using the full cost method of accounting.

              business of Swift or such Restricted Subsidiary;

     (d)      for purposes of the covenant described under "-- Certain

              acquisition of, the Property that is subject thereto.

              Transaction Date), assuming for the purposes of this measurement
              the continuation of market interest rates prevailing on the
              Transaction Date and base interest rates in respect of floating
              interest rate obligations equal to the base interest rates on such
              obligations in effect as of the Transaction Date; provided, that

              Consolidated Interest Expense with respect to Indebtedness
              Incurred or retired by Swift or any of its Restricted Subsidiaries

quarter period preceding the Transaction Date through and including the
Transaction Date:

     (a)      Swift or any of its Restricted Subsidiaries shall have engaged in
              any Asset Sale, EBITDA for such period shall be reduced by an
              amount equal to the EBITDA (if positive), or increased by an

              the assets that are the subject of such Asset Sale for such period
              calculated on a pro forma basis as if such Asset Sale and any
              related retirement of Indebtedness had occurred on the first day
              of such period; or

     (b)      (1)      Swift or any of its Restricted Subsidiaries shall have
                       acquired or made any Investment in any material assets,

           (2)      the transaction giving rise to the need to calculate the
                    Consolidated Interest Coverage Ratio is such an Investment
                    or acquisition,

     quarter period.

              of another person secured by any Lien on any Property of such
              Person (whether or not such obligation is assumed by such Person),
              the amount of such obligation being deemed to be the lesser of the
              value of such Property or the amount of the obligation so secured;

              however, that (except as required by law) such custodian is not
              authorized to make any deduction from the amount payable to the
              holder of such depository receipt from any amount received by the
              custodian

              in respect of the U.S. Government Obligation or the specific
              payment or principal of or interest on the U.S. Government
              Obligation evidenced by such depository receipt.

     "Volumetric Production Payments" means production payment obligations
recorded as deferred revenue in accordance with GAAP, together with all
undertakings and obligations in connection therewith.

     "Voting Stock" of any Person means Capital Stock of such Person that
ordinarily has voting power for the election of directors (or persons performing
similar functions ) of such Person whether at all times or only so long as no
senior class of securities has such voting power by reason of any contingency.

     "Wholly Owned Subsidiary" means, at any time, a Restricted Subsidiary of
Swift all the Voting Stock of which (other than directors' qualifying shares) is
at such time owned, directly or indirectly, by us and our other Wholly Owned
Subsidiaries.

DEFEASANCE AND COVENANT DEFEASANCE

     The Indenture provides that we will, at our election at any time, be
discharged from our obligations with respect to the Notes ("Legal Defeasance")
except for certain obligations to:

     (a)      exchange or register the transfer of Notes;

     (b)      to replace stolen, lost or mutilated Notes;

     (c)      to maintain paying agencies; and

     (d)      to hold moneys for payment in trust.

In addition, the Indenture provides that if we take the actions described below,
we may omit to comply with certain covenants, including those described under
"-- Repurchase at the Option of Holders Upon a Change of Control," "-- Certain
Covenants" and in clauses (d) and (e) under the first paragraph of "-- Merger,
Consolidation and Sale of Substantially All Assets." Additionally, the
occurrence of the Events of Default described below in clauses (c) and (d) (with
respect to such covenants) and clauses (e), (f), (g) (with respect to
Significant Subsidiaries) and (h) under "-- Events of Default and Notice" will
be deemed not to be or result in an Event of Default.

     Such Legal Defeasance and Covenant Defeasance may occur only if, among
other things, we:

     (a)      deposit in trust for the benefit of the Holders of the Notes,
              money or U.S. Government Obligations, or a combination thereof,
              that, through the payment of principal, premium, if any, and
              interest in respect thereof in accordance with their terms, will
              provide money in an amount sufficient to pay the principal of and
              any premium and interest on the Notes at the Stated Maturity
              thereof or on earlier redemption in accordance with the terms of
              the Indenture and the Notes; and

     (b)      in the case of Legal Defeasance, deliver to the Trustee an Opinion
              of Counsel

           (1)      to the effect that:

                   (A)      we have received from, or there has been published
                            by, the United States Internal Revenue Service a
                            ruling, or

                   (B)      since the date of the Indenture there has been a
                            change in the applicable federal income tax law,

                   in either case to the effect that Holders of the Notes will
                   not recognize gain or loss for federal income tax purposes as
                   a result of such deposit, defeasance and discharge and will
                   be subject to federal income tax on the same amount, in the
                   same manner and at the same times as would have been the case
                   if such deposit, defeasance and discharge were not to occur,
                   and

                                      S-83
<PAGE>   84

           (2)      that the resulting trust will not be an "Investment Company"
                    within the meaning of the Investment Company Act of 1940
                    unless such trust is qualified thereunder or exempt from
                    regulation thereunder;

     (c)      in the case of Covenant Defeasance, deliver to the Trustee on
              Opinion of Counsel to the effect that:

           (1)      Holders of the Notes will not recognize gain or loss for
                    federal income tax purposes as a result of such deposit and
                    defeasance of certain obligations and will be subject to
                    federal income tax on the same amount, in the same manner
                    and at the same times as would have been the case if such
                    deposit and defeasance were not to occur, and

           (2)      that the resulting trust will not be an "Investment Company"
                    within the meaning of the Investment Company Act of 1940
                    unless such trust is qualified thereunder or exempt from
                    regulation thereunder.

     If we were to exercise this option and the Notes were declared due and
payable because of the occurrence of any Event of Default, the amount of money
and U.S. Government Obligations so deposited in trust would be sufficient to pay
amounts due on the Notes at the time of their Stated Maturity but may not be
sufficient to pay amounts due on the Notes upon any acceleration resulting from
such Event of Default. In such case, we would remain liable for such payments.

     If we exercise either of the options described above, each Subsidiary
Guarantor, if any, will be released from all its obligations under its
Subsidiary Guaranty.

EVENTS OF DEFAULT AND NOTICE

     The following are summaries of Events of Default under the Indenture with
respect to the Notes:

     (a)      failure to pay any interest on the Notes when due, continued for
              30 days;

     (b)      failure to pay principal of (or premium, if any, on) the Notes
              when due;

     (c)      failure to comply with the provisions of the Indenture described
              under "Merger, Consolidation and Sale of Substantially All
              Assets";

     (d)      failure to perform any other covenant of Swift or any Subsidiary
              Guarantor in the Indenture, continued for 30 days after written
              notice to us from the Trustee or the Holders of at least 25% in
              aggregate principal amount of the outstanding Notes;

     (e)      a default by us or any Restricted Subsidiary under any
              Indebtedness for borrowed money in an aggregate amount greater
              than $5.0 million (other than Non-recourse Purchase Money
              Indebtedness) that results in acceleration of the maturity of such
              Indebtedness, or failure to pay any such Indebtedness at maturity,
              if such Indebtedness is not discharged or such acceleration is not
              rescinded or annulled within 10 days after written notice as
              provided in the Indenture;

     (f)      one or more final judgments or orders by a court of competent
              jurisdiction are entered against us or any Restricted Subsidiary
              in an uninsured or unindemnified aggregate amount outstanding at
              any time in excess of $5.0 million and such judgments or orders
              are not discharged, waived, stayed, satisfied or bonded for a
              period of 60 consecutive days;

     (g)      certain events of bankruptcy, insolvency or reorganization with
              respect to Swift or any Significant Subsidiary; or

     (h)      a Subsidiary Guaranty ceases to be in full force and effect (other
              than in accordance with the terms of the Indenture and such
              Subsidiary Guaranty) or a Subsidiary Guarantor denies or
              disaffirms its obligations under its Subsidiary Guaranty.

                                      S-84
<PAGE>   85

     The Indenture provides that if an Event of Default (other than an Event of
Default described in clause (g) above) with respect to the Notes at the time
outstanding shall occur and be continuing, either the Trustee or the Holders of
at least 25% in aggregate principal amount of the outstanding Notes by notice as
provided in the Indenture may declare the principal amount of the Notes to be
due and payable immediately. If an Event of Default described in clause (g)
above with respect to the Notes at the time outstanding shall occur, the
principal amount of all the Notes will automatically, and without any action by
the Trustee or any Holder, become immediately due and payable. After any such
acceleration, but before a judgment or decree based on acceleration, the Holders
of at least a majority in aggregate principal amount of the outstanding Notes
may, under certain circumstances, rescind and annul such acceleration if all
Events of Default, other than the nonpayment of accelerated principal (or other
specified amount), have been cured or waived as provided in the Indenture.

     Subject to the provisions of the Indenture relating to the duties of the
Trustee, in case an Event of Default shall occur and be continuing, the Trustee
will be under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the Holders of the Notes, unless
such Holders shall have offered to the Trustee reasonable indemnity. Subject to
such provisions for the indemnification of the Trustee, the Holders of at least
a majority in aggregate principal amount of the outstanding Notes will have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Notes.

     No Holder of Notes will have any right to institute any proceeding with
respect to the Indenture, or for the appointment of a receiver or a trustee, or
for any other remedy thereunder, unless:

     (a)      such Holder has previously given to the Trustee written notice of
              a continuing Event of Default with respect to the Notes;

     (b)      the Holders of at least 25% in aggregate principal amount of the
              outstanding Notes have made written request, and such Holder or
              Holders have offered reasonable indemnity, to the Trustees to
              institute such proceeding as trustee; and

     (c)      the Trustee has failed to institute such proceeding and has not
              received from the Holders of at least a majority in aggregate
              principal amount of the outstanding Notes a direction inconsistent
              with such request, within 60 days after such notice, request and
              offer.

However, such limitations do not apply to a suit instituted by a Holder of Notes
for the enforcement of payment of the principal of or any premium or interest on
such Notes on or after the applicable due date specified in such Notes.

MODIFICATION OF THE INDENTURE; WAIVER

     The Indenture provides that modifications and amendments of the Indenture
may be made by us, any Subsidiary Guarantors and the Trustee without the consent
of any Holders of Notes in certain limited circumstances, including:

     (a)      to cure any ambiguity, omission, defect or inconsistency;

     (b)      to provide for the assumption of the obligations of Swift under
              the Indenture upon the merger, consolidation or sale or other
              disposition of all or substantially all the assets of Swift and
              the Restricted Subsidiaries taken as a whole and certain other
              events specified in the provisions of the Indenture described
              under "Merger, Consolidation and Sale of Substantially All
              Assets";

     (c)      to provide for uncertificated Notes in addition to or in place of
              certificated Notes;

     (d)      to comply with any requirement of the SEC in order to effect or
              maintain the qualification of the Indenture under the 1939 Act;

                                      S-85
<PAGE>   86

     (e)      to make any change that does not adversely affect the rights of
              any Holder of Notes in any material respect;

     (f)      to add or remove Subsidiary Guarantors pursuant to the procedure
              set forth in the Indenture; and

     (g)      certain other modifications and amendments as set forth in the
              Indenture.

     The Indenture contains provisions permitting us, any Subsidiary Guarantors
and the Trustee with the written consent of the Holders of not less than a
majority in aggregate principal amount of the outstanding Notes, to execute
supplemental indentures or amendments adding any provisions to or changing or
eliminating any of the provisions of the Indenture or modifying the rights of
the Holders of the Notes, except that no such supplemental indenture, amendment
or waiver may, without the consent of all the Holders of outstanding Notes,
among other things:

     (a)      reduce the principal amount of Notes whose Holders must consent to
              an amendment or waiver;

     (b)      reduce the rate of or change the time for payment of interest on
              any Notes;

     (c)      change the currency in which any amount due in respect of the
              Notes is payable;

     (d)      reduce the principal of or any premium on or change the Stated
              Maturity of any Notes or alter the redemption or repurchase
              provisions with respect thereto;

     (e)      reduce the relative ranking of any Notes;

     (f)      release any security that may have been granted to the Trustee in
              respect of the Notes;

     (g)      at any time after a Change of Control has occurred, change the
              time at which the Change of Control Offer relating thereto must be
              made or at which the Notes must be repurchased pursuant to such
              Change of Control Offer; or

     (h)      make certain other significant amendments or modifications as
              specified in the Indenture.

     The Holders of at least a majority in principal amount of the outstanding
Notes may waive compliance by Swift with certain restrictive provisions of the
Indenture. The Holders of at least a majority in principal amount of the
outstanding Notes may waive any past default under the Indenture, except a
default in the payment of principal, premium or interest and certain covenants
and provisions of the Indenture that cannot be amended without the consent of
the Holders of each outstanding Note.

     No amendment may be made to the subordination provisions of the Indenture
that adversely affects the rights of any holder of Senior Indebtedness then
outstanding unless the holders of such Senior Indebtedness (or their
Representative) consent to such change. The consent of the Holders of the Notes
is not necessary under the Indenture to approve the particular form of any
proposed amendment. It is sufficient if such consent approves the substance of
the proposed amendment. After an amendment under the Indenture becomes
effective, we are required to mail to each registered Holder of the Notes at
such Holder's address appearing in the Security Register a notice briefly
describing such amendment. However, the failure to give such notice to all
Holders of the Notes, or any defect therein, will not impair or affect the
validity of the amendment.

NOTICES

     Notices to Holders of the Notes will be given by mail to the addresses of
such Holders as they may appear in the Security Register.

GOVERNING LAW

     The Indenture and the Notes are governed by and construed in accordance
with the internal laws of the State of New York without reference to principles
of conflicts of law.

TRUSTEE

     Bank One, N.A. is the Trustee under the Indenture. The Trustee maintains
normal banking relationships with us and our Subsidiaries and may perform
certain services and transact other business with us and our Subsidiaries from
time to time in the ordinary course of business.

BOOK-ENTRY SYSTEM

     The Notes will be initially issued in the form of one or more Global
Securities registered in the name of The Depository Trust Company, "DTC", or its
nominee.

     Upon the issuance of a Global Security, DTC or its nominee will credit the
accounts of Persons holding through it with the respective principal amounts of
the Notes represented by such Global Security purchased by such Persons in this
offering of the Notes. Such accounts shall be designated by the Underwriters.
Ownership of beneficial interests in a Global Security will be limited to
Persons that have accounts with DTC, "participants", or Persons that may hold
interests through participants. Ownership of beneficial interests in a Global
Security will be shown on, and the transfer of that ownership interest will be
effected only through, records maintained by DTC (with respect to participants'
interests) and such participants (with respect to the owners of beneficial
interests in such Global Security other than participants). The laws of some
jurisdictions require that certain purchasers of securities take physical
delivery of such securities in definitive form. Such limits and such laws may
impair the ability to transfer beneficial interests in a Global Security.

     Payment of principal of and interest on Notes represented by a Global
Security will be made in immediately available funds to DTC or its nominee, as
the case may be, as the sole registered owner and the sole holder of the Notes
represented thereby for all purposes under the Indenture. We have been advised
by DTC that upon receipt of any payment of principal of or interest on any
Global Security, DTC will immediately credit, on its book-entry registration and
transfer system, the accounts of participants with payments in amounts
proportionate to their respective beneficial interests in the principal or face
amount of such Global Security as shown on the records of DTC. Payments by
participants to owners of beneficial interests in a Global Security held through
such participants will be governed by standing instructions and customary
practices as is now the case with securities held for customer accounts
registered in "street name" and will be the sole responsibility of such
participants.

     A Global Security may not be transferred except as a whole by DTC or a
nominee of DTC to a nominee of DTC or to DTC. A Global Security is exchangeable
for certificated Notes only if:

     (a)      DTC notifies us that it is unwilling or unable to continue as a
              depositary for such Global Security or if at any time DTC ceases
              to be a clearing agency registered under the Exchange Act;

     (b)      we in our discretion at any time determine not to have all the
              Notes represented by such Global Security; or

     (c)      there shall have occurred and be continuing a Default or an Event
              of Default with respect to the Notes represented by such Global
              Security.

     Any Global Security that is exchangeable for certificated Notes pursuant to
the preceding sentence will be exchanged for certificated Notes in authorized
denominations and registered in such names as DTC or any successor depositary
holding such Global Security may direct. Subject to the foregoing, a Global
Security is not exchangeable, except for a Global Security of like denomination
to be registered in the

                                      S-87
<PAGE>   88

name of DTC or any successor depositary or its nominee. In the event that a
Global Security becomes exchangeable for certificated Notes,

     (a)      certificated Notes will be issued only in fully registered form in
              denominations of $1,000 or integral multiples thereof,

     (b)      payment of principal of, and premium, if any, and interest on, the
              certificated Notes will be payable, and the transfer of the
              certificated Notes will be registerable, at the office or agency
              of Swift maintained for such purposes, and

     (c)      no service charge will be made for any registration of transfer or
              exchange of the certificated Notes, although we may require
              payment of a sum sufficient to cover any tax or governmental
              charge imposed in connection therewith.

     So long as DTC or any successor depositary for a Global Security, or any
nominee, is the registered owner of such Global Security, DTC or such successor
depositary or nominee, as the case may be, will be considered the sole owner or
holder of the Notes represented by such Global Security for all purposes under
the Indenture and the Notes. Except as set forth above, owners of beneficial
interests in a Global Security will not be entitled to have the Notes
represented by such Global Security registered in their names, will not receive
or be entitled to receive physical delivery of certificated Notes in definitive
form and will not be considered to be the owners or holders of any Notes under
such Global Security. Accordingly, each Person owning a beneficial interest in a
Global Security must rely on the procedures of DTC or any successor depositary,
and, if such Person is not a participant, on the procedures of the participant
through which such Person owns its interest, to exercise any rights of a Holder
under the Indenture. We understand that under existing industry practices, in
the event that we request any action of Holders or that an owner of a beneficial
interest in a Global Security desires to give or take any action that a Holder
is entitled to give or take under the Indenture, DTC or any successor depositary
would authorize the participants holding the relevant beneficial interest to
give or take such action and such participants would authorize beneficial owners
owning through such participants to give or take such action or would otherwise
act upon the instructions of beneficial owners owning through them.

     DTC has advised us that DTC is a limited-purpose trust company organized
under the Banking Law of the State of New York, a member of the Federal Reserve
System, a "clearing corporation" within the meaning of the New York Uniform
Commercial Code and a "clearing agency" registered under the Exchange Act. DTC
was created to hold the securities of its participants and to facilitate the
clearance and settlement of securities transactions among its participants in
such securities through electronic book-entry changes in accounts of the
participants, thereby eliminating the need for physical movement of securities
certificates. DTC's participants include securities brokers and dealers (which
may include the Underwriters), banks, trust companies, clearing corporations and
certain other organizations some of whom (or their representatives) own DTC.
Access to DTC's book-entry system is also available to others, such as banks,
brokers, dealers and trust companies, that clear through or maintain a custodial
relationship with a participant, either directly or indirectly.

     Although DTC has agreed to the foregoing procedures in order to facilitate
transfers of interests in Global Securities among participants of DTC, it is
under no obligation to perform or continue to perform such procedures, and such
procedures may be discontinued at any time. None of Swift, the Trustee or the
Underwriters will have any responsibility for the performance by DTC or its
participants or indirect participants of their respective obligations under the
rules and procedures governing their operations.

The underwriters are obligated to purchase all the notes if they purchase any of
the notes.

     The underwriters, for whom Salomon Smith Barney Inc., CIBC World Markets
Corp., Morgan Stanley & Co. Incorporated, Credit Suisse First Boston
Corporation, Banc One Capital Markets, Inc., ABN AMRO Incorporated and SG Cowen
Securities Corporation are acting as representatives, propose to offer some of
the notes directly to the public at the public offering price set forth on the
cover page of this prospectus supplement and some of the notes to certain
dealers at the public offering price less a concession not in excess of 0.50% of
the principal amount of notes. The underwriters may allow, and such dealers may
reallow, a concession not in excess of 0.25% of the principal amount of the
notes on sales to certain other dealers. After the initial offering of the notes
to the public, the public offering price and such concessions may be changed by
the representatives.

     The following table shows the underwriting discounts and commissions to be
paid to the underwriters by us in connection with this offering, expressed as a
percentage of the principal amount of the notes.

</TABLE>

     In connection with the offering, Salomon Smith Barney Inc., on behalf of
the underwriters, may purchase and sell notes in the open market. These
transactions may include over-allotment, syndicate covering transactions and
stabilizing transactions. Over-allotment involves syndicate sales of notes in
excess of the principal amount of notes to be purchased by the underwriters in
the offering, which creates a syndicate short position. Syndicate covering
transactions involve purchases of the notes in the open market after the
distribution has been completed in order to cover syndicate short positions.
Stabilizing transactions consist of certain bids of purchases of notes made for
the purpose of preventing or retarding a decline in the market price of the
notes while the offering is in progress.

     The underwriters also may impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases notes originally sold by that syndicate
member.

     Any of these activities may cause the price of the notes to be higher than
the price that otherwise would exist in the open market in the absence of such
transactions. These transactions may be effected in the over-the-counter market
or otherwise and, if commenced, may be discontinued at any time.

     We estimate that our total expenses for this offering and the concurrent
common stock offering will be $820,000.

     The representatives have performed certain investment banking and advisory
services for us from time to time for which they have received customary fees
and expenses. The representatives may, from time to time, engage in transactions
with and perform services for us in the ordinary course of their business.
Salomon Smith Barney Inc., CIBC World Markets Corp. and Credit Suisse First
Boston Corporation are also acting as representatives for the underwriters in
the concurrent common stock offering.

     Certain of the underwriters or their affiliates are lenders under our
credit facility, which is expected to be repaid with the net proceeds from this
offering and the concurrent common stock offering.

     The rules of the National Association of Securities Dealers, Inc. provide
that no NASD member shall participate in a public offering of an issuer's
securities where more than 10% of the net offering proceeds are intended to be
paid to members participating in the distribution of the offering or affiliated
persons of such members, unless a qualified independent underwriter is engaged
on the terms provided in the NASD's Conduct Rules. It is anticipated that the
respective affiliates of CIBC World Markets Corp., Banc One Capital Markets,
Inc., ABN AMRO Incorporated and SG Cowen Securities Corporation will be
receiving more than 10% of the proceeds from this offering in their capacity as
lenders under our credit facility.

     In view of this use of proceeds, this offering is being conducted in
accordance with Rule 2720 of the NASD's Conduct Rules. Rule 2720 requires that
the yield at which this offering will be distributed to the public will be no
lower than that recommended by a qualified independent underwriter. Accordingly,
Salomon Smith Barney Inc. is acting as the qualified independent underwriter in
pricing this offering, preparing this prospectus supplement and conducting due
diligence with respect thereto.

     We have agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make in respect of any of those
liabilities.

                                 LEGAL OPINIONS

     Jenkens & Gilchrist, a Professional Corporation, Houston, Texas, will issue
an opinion for Swift regarding the legality of the notes offered by this

     The following abbreviations and terms have the indicated meanings when used
in this prospectus supplement:

     Bbl -- Barrel or barrels of oil.

     Bcf -- Billion cubic feet of gas.

     Bcfe -- Billion cubic feet of gas equivalent (see Mcfe).

     Development Well -- A well drilled within the presently proved productive
area of an oil or gas reservoir, as indicated by reasonable interpretation of
available data, with the objective of completing that reservoir.

     Dry Well -- An exploratory or development well that is not a producing
well.

     Exploratory Well -- A well drilled either in search of a new, as yet
undiscovered oil or gas reservoir or to greatly extend the known limits of a
previously discovered reservoir.

     Gross Acre -- An acre in which a working interest is owned. The number of
gross acres is the total number of acres in which a working interest is owned.

     Gross Well -- A well in which a working interest is owned. The number of
gross wells is the total number of wells in which a working interest is owned.

     MBbl -- Thousand barrels of oil.

     Mcf -- Thousand cubic feet of gas.

     Mcfe -- Thousand cubic feet of gas equivalent, which is determined using
the ratio of one barrel of oil, condensate, or gas liquids to 6 Mcf of gas.

     MMBbl -- Million barrels of oil.

     MMBtu -- Million British thermal units, which is a heating equivalent
measure for gas and is an alternate measure of gas reserves, as opposed to Mcf,
which is strictly a measure of gas volumes. Typically, prices quoted for gas are
designated as price per MMBtu, the same basis on which gas is contracted for
sale.

     MMcf -- Million cubic feet of gas.

     MMcfe -- Million cubic feet of gas equivalent (see Mcfe).

     Net Acre -- A net acre is deemed to exist when the sum of fractional
ownership working interests in gross acres equals one. The number of net acres
is the sum of fractional working interests owned in gross acres expressed as
whole numbers and fractions thereof.

     Net Well -- A net well is deemed to exist when the sum of fractional
ownership working interests in gross wells equals one. The number of net wells
is the sum of fractional working interests owned in gross wells expressed as
whole numbers and fractions thereof.

     Producing Well -- An exploratory or development well found to be capable of
producing either oil or gas in sufficient quantities to justify completion as an
oil or gas well.

     Proved Developed Oil and Gas Reserves -- Reserves that can be expected to
be recovered through existing wells with existing equipment and operating
methods.

     Proved Oil and Gas Reserves -- The estimated quantities of crude oil, gas
and gas liquids that geological and engineering data demonstrate with reasonable
certainty to be recoverable in future years from known reservoirs under existing
economic and operating conditions, that is, prices and costs as of the date the
estimate is made.

                                      S-91
<PAGE>   92

     Proved Undeveloped Oil and Gas Reserves -- Reserves that are expected to be
recovered from new wells on undrilled acreage or from existing wells where a
relatively major expenditure is required for recompletion.

     PV-10 Value -- The estimated future net revenue to be generated from the
production of proved reserves discounted to present value using an annual
discount rate of 10%. These amounts are calculated net of estimated production
costs and future development costs, using prices and costs in effect as of a
certain date, without escalation and without giving effect to non-property
related expenses, such as general and administrative expenses, debt service,
future income tax expense, or depreciation, depletion, and amortization.

     Working Interest -- The operating interest under an oil, gas and mineral
lease or other property interest covering a specific tract or tracts of land.
The owner of a Working Interest has the right to explore for, drill and produce
the oil, gas and other minerals covered by such lease or other property interest

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders and Board of Directors of Swift Energy Company:

     We have audited the accompanying consolidated balance sheets of Swift
Energy Company (a Texas corporation) and subsidiaries as of December 31, 1998
and 1997, and the related consolidated statements of income, stockholders'
equity, and cash flows for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

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

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Swift Energy Company and
subsidiaries as of December 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation. The accompanying consolidated financial
statements include the accounts of Swift Energy Company (Swift) and its wholly
owned subsidiaries (collectively referred to as the "Company"), which are
engaged in the exploration, development, acquisition, and operation of oil and
natural gas properties, with particular emphasis on U.S. onshore natural gas
reserves. The Company also has oil and gas activities in New Zealand, Venezuela,
and Russia. The Company's investments in associated oil and gas partnerships and
its joint ventures are accounted for using the proportionate consolidation
method, whereby the Company's proportionate share of each entity's assets,
liabilities, revenues, and expenses is included in the appropriate
classifications in the consolidated financial statements. Intercompany balances
and transactions have been eliminated in preparing the consolidated statements.
In the second quarter of 1998, the Company began netting supervision fees
against general and administrative expenses and oil and gas production costs.
This reclassification has been made for all periods presented. Certain other
reclassifications have been made to prior year amounts to conform to the current
year presentation.

     Unaudited Interim Information. The unaudited interim consolidated financial
statements as of June 30, 1999 and for each of the six month periods ended June
30, 1999 and 1998, included herein, have been prepared pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, they do not
include all of the information and footnotes required by generally accepted
accounting principles for complete financial statements. In the opinion of the
Company's management, the unaudited interim consolidated financial statements
include all adjustments (consisting only of normal recurring adjustments) to
present fairly the information set forth herein. The interim financial results
should not be regarded as indicative of operating results for an entire year.

     Use of 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, if any, at the
date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from
estimates.

     Property and Equipment. The Company follows the "full-cost" method of
accounting for oil and gas property and equipment costs. Under this method of
accounting, all productive and nonproductive costs incurred in the acquisition,
exploration, and development of oil and gas reserves are capitalized. Under the
full-cost method of accounting, such costs may be incurred both prior to or
after the acquisition of a property and include lease acquisitions, geological
and geophysical services, drilling, completion, equipment, and certain general
and administrative costs directly associated with acquisition, exploration, and
development activities. Interest costs related to unproved properties are also
capitalized to unproved oil and gas properties. The Company's management
believes this capitalization of such costs is appropriate under full-cost
accounting rules. General and administrative costs related to production and
general overhead are expensed as incurred.

     No gains or losses are recognized upon the sale or disposition of oil and
gas properties, except in transactions that involve a significant amount of
reserves. The proceeds from the sale of oil and gas properties are generally
treated as a reduction of oil and gas property costs. Fees from associated oil
and gas exploration and development limited partnerships are credited to oil and
gas property costs to the extent they do not represent reimbursement of general
and administrative expenses currently charged to expense.

     Future development, site restoration, and dismantlement and abandonment
costs, net of salvage values, are estimated on a property-by-property basis
based on current economic conditions and are amortized to expense as the
Company's capitalized oil and gas property costs are amortized. The

                     SWIFT ENERGY COMPANY AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

Company's properties are all onshore, and historically the salvage value of the
tangible equipment offsets the Company's site restoration and dismantlement and
abandonment costs. The Company expects that this relationship will continue in
the future.

     The Company computes the provision for depreciation, depletion, and
amortization of oil and gas properties on the unit-of-production method. Under
this method, the Company computes the provision by multiplying the total
unamortized costs of oil and gas properties -- including future development,
site restoration, and dismantlement and abandonment costs, but excluding costs
of unproved properties -- by an overall rate determined by dividing the physical
units of oil and gas produced during the period by the total estimated units of
proved oil and gas reserves. This calculation is done on a country-by-country
basis for those countries with oil and gas production. The Company currently has
production in the United States only. All other equipment is depreciated by the
straight-line method at rates based on the estimated useful lives of the
property. Repairs and maintenance are charged to expense as incurred. Renewals
and betterments are capitalized.

     The cost of unproved properties not being amortized is assessed quarterly,
on a country-by-country basis, to determine whether such properties have been
impaired. Domestically, any impairment assessed is added to the cost of proved
properties being amortized. To the extent costs accumulated in the Company's
international initiatives are determined by management to be costs that will not
result in the addition of proved reserves, any impairment is charged to income.
In determining whether such costs should be impaired, the Company's management
evaluates, among other factors, current oil and gas industry conditions,
international economic conditions, capital availability, foreign currency
exchange rates, the political stability in the countries in which the Company
has an investment, and available geological and geophysical information.

     Domestic Properties. At the end of each quarterly reporting period, the
unamortized cost of oil and gas properties, net of related deferred income
taxes, is limited to the sum of the estimated future net revenues from proved
properties using current period-end prices, discounted at 10%, and the lower of
cost or fair value of unproved properties, adjusted for related income tax
effects ("Ceiling Test"). This calculation is done on a country-by-country basis
for those countries with proved reserves. Currently, the Company has proved
reserves in the United States only.

     The calculation of the Ceiling Test and provision for depreciation,
depletion, and amortization is based on estimates of proved reserves. There are
numerous uncertainties inherent in estimating quantities of proved reserves and
in projecting the future rates of production, timing, and plan of development.
The accuracy of any reserves estimate is a function of the quality of available
data and of engineering and geological interpretation and judgment. Results of
drilling, testing, and production subsequent to the date of the estimate may
justify revision of such estimate. Accordingly, reserves estimates are often
different from the quantities of oil and gas that are ultimately recovered.

     As a result of low oil and gas prices at September 30, 1998, the Company
reported a non-cash write-down on a before-tax basis of $77.2 million ($50.9
million after tax) on its domestic properties.

     Foreign Properties. In addition, during the third quarter of 1998, as it
does every reporting period, the Company evaluated all of its foreign
unevaluated properties (a detailed description of which is included in Note 8 to
the Company's financial statements), especially in light of the then increased
volatility in the oil and gas markets, international uncertainty, and turmoil in
the world capital markets.

     The increased volatility in the oil and gas markets affected the Company's
cash flows available for further exploration and forced the Company to scale
back its capital expenditures budget. All of this was further accentuated in
Venezuela by the economic crisis there, the results of which were to diminish
the availability of financing in international markets for Venezuelan projects
and to worsen Venezuelan currency problems. Petroleos de Venezuela, S.A.
layoffs, threatened oil worker strikes, reduced OPEC
                                       F-8

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

production allocations, and other third quarter 1998 events highlight the
problems that the oil and gas industry is encountering in Venezuela. As a result
of these and other factors, in the third quarter of 1998, the Company decided to
impair all $2.8 million of costs related to its Venezuelan oil and gas
exploration activities.

     In addition, in the third quarter of 1998, the Company impaired all $10.8
million of costs relating to its Russian activities. This impairment is
attributed not only to the volatility in the oil and gas markets and the severe
tightening of international credit markets discussed above, but also to the
increased political instability in Russia and the August 1998 collapse of the
Russian currency. The Company believed that the economic and political situation
would result in the lack of capital to develop these reserves underlying the
Company's net profits interest in the near term. Although the Company continues
to believe that its net profits interest is legally enforceable under
international law, for all these reasons the Company does not believe that
realistically it will be able to recover its investment in Russia in the
foreseeable future. Because of this, the Company determined that it no longer
had a reasonable basis to continue capitalization of the costs in its Russia
cost center.

     The combination of the third-quarter domestic full-cost ceiling write-down
and foreign activities impairment charges reduced before-tax earnings by $90.8
million ($59.9 million after tax). Since such impairment, any costs incurred in
Venezuela and Russia have been charged to income.

     Also, during the fourth quarter of 1998, the Company's $0.4 million portion
of drilling costs associated with an unsuccessful exploratory well drilled by
another operator in New Zealand was charged to income as depreciation,
depletion, and amortization costs.

     Oil and Gas Revenues. Gas revenues are reported using the entitlement
method in which the Company recognizes its ownership interest in natural gas
production as revenue. If the Company's sales exceed its ownership share of
production, the differences are reported as deferred revenue. Natural gas
balancing receivables are reported when the Company's ownership share of
production exceeds sales. As of December 31, 1998, the Company did not have any
material natural gas imbalances.

     Deferred Charges. Legal and accounting fees, underwriting fees, printing
costs, and other direct expenses associated with the public offering in November
1996 of the Company's 6.25% Convertible Subordinated Notes (the "Notes") have
been capitalized and are being amortized over the life of the Notes, which
mature on November 15, 2006. The balance of these issuance costs at December 31,
1998 was $3,826,864, net of accumulated amortization of $723,136. The issuance
costs associated with its new $250.0 million revolving credit facility (the "New
Credit Facility"), which closed in August 1998, have been capitalized and are
being amortized over the life of the facility, which will extend until August
2002. The balance of these issuance costs at December 31, 1998, was $507,094,
net of accumulated amortization of $51,600.

     Limited Partnerships and Joint Ventures. Between 1984 and 1995, the Company
formed limited partnerships and joint ventures for the purpose of acquiring
interests in producing oil and gas properties and, since 1993, partnerships
engaged in drilling for oil and gas reserves. The Company serves as managing
general partner or manager of these entities.

     The Company acquired producing oil and gas properties and transferred those
properties to the partnership entities which invested in producing oil and gas
properties. These transfers were at cost, including interest, other carrying
costs, closing costs, and screening and evaluation costs of properties not
acquired, or, in certain instances, at fair market value based upon the opinion
of an independent expert. These costs were reduced by net operating revenues
from the effective date of the acquisition to the date of transfer to these
entities. Such net operating revenue amounts totaled approximately $100,000 and
$300,000 in 1997 and 1996, respectively. With the acquisitions made in 1997, the
Company fulfilled its

                                       F-9
<PAGE>   102
                     SWIFT ENERGY COMPANY AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

responsibility of acquiring properties for such partnerships, as these
partnerships are fully invested in properties.

     Commencing in September 1993, the Company began offering, on a private
placement basis, general and limited partnership interests in limited
partnerships to be formed to drill for oil and gas. As managing general partner,
the Company pays for all front-end costs incurred in connection with these
offerings, for which the Company receives an interest in the partnerships.
Through December 31, 1998, approximately $66.1 million had been raised in
thirteen partnerships, one each formed in 1993 and 1994; three each in 1995,
1996, and 1997; and two in 1998. In June and October 1998, the Company closed
the twelfth and thirteenth partnerships with total subscriptions of
approximately $3.2 million and $4.3 million, respectively. Costs of syndication
and qualification of these limited partnerships incurred by the Company have
been deferred. Under the current private limited partnership offerings, selling
and formation costs borne by the Company serve as the Company's general partner
contribution to such partnerships.

     During 1996, the limited partners in 18 partnerships, which had been in
operation over nine years and had produced a substantial majority of their
reserves, voted to sell their remaining properties and liquidate the limited
partnerships. Of these partnerships, 10 were the earliest public income
partnerships formed between 1984 and 1986. In early 1997, eight private drilling
partnerships formed between 1979 and 1985 were liquidated. During 1997, the
limited partners in an additional 11 partnerships, formed in 1990 and 1991,
voted to sell their properties and liquidate the limited partnerships, which
occurred in June 1998.

     In October 1998, the Company notified investors in 63 Company-managed
partnerships, formed between 1986 and 1994, that it had delayed calling investor
meetings to consider its purchase of all of the oil and gas properties owned by
these partnerships, which was proposed in March 1998. This decision principally
reflected significant market changes that had occurred during the long period
necessary for regulatory review of soliciting materials, the age of the
third-party appraisals of these partnership properties, and the much publicized
weakness in both the equity and debt markets for energy companies. During the
last six months, the weakness in oil and natural gas prices has deepened,
creating concern over the appropriateness of selling properties at this time.
The Company expects to continue to re-evaluate the status and operation of these
partnerships, whether to propose some form of liquidating transaction and, if
so, when and in what form.

     Hedging Activities. The Company's revenues are primarily the result of
sales of its oil and natural gas production. Market prices of oil and natural
gas may fluctuate and adversely affect operating results. To mitigate some of
this risk, the Company engages periodically in certain limited hedging
activities, but only to the extent of buying protection price floors for
portions of its and the limited partnership oil and natural gas production.
Costs and any benefits derived from these price floors are accordingly recorded
asa reduction or an increase, as applicable, in oil and gas sales revenue and
were not significant for any year presented. The costs to purchase put options
are amortized over the option period. The costs related to 1998 hedging
activities totaled approximately $377,000 with benefits of approximately
$101,000 being received, resulting in a net cash outlay of approximately
$276,000 or $0.007 per Mcfe. The costs related to the open contracts as of
December 31, 1998, totaled approximately $252,000 and had a fair market value of
$267,000.

     Income Taxes. The Company accounts for income taxes using the liability
method, and deferred taxes are determined based on the estimated future tax
effects of differences between the financial statement and tax bases of assets
and liabilities given the provisions of the enacted tax laws.

     Deferred Revenues. In May 1992, the Company purchased interests in certain
wells using funds provided by the Company's sale of a volumetric production
payment in these properties to Enron. Under the production payment agreement,
the Company is required to deliver to Enron approximately 9.5 Bcf over an
eight-year period, or for such longer period as is necessary to deliver a
specified heating equivalent

                                      F-10
<PAGE>   103
                     SWIFT ENERGY COMPANY AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

quantity at an average price of $1.115 per MMBtu. The Company receives all
proceeds from sale of excess gas at current market prices plus the proceeds from
sale of oil or condensate. Volumes remaining to be delivered through October
2000 under the volumetric production payment were approximately 1.1 Bcf at
December 31, 1998, and were not included in the Company's proved reserves. Net
proceeds from the sale of the production payment were recorded as deferred
revenues. Deliveries under the production payment agreement are recorded as oil
and gas sales revenues and a corresponding reduction of deferred revenues.

     Cash and Cash Equivalents. The Company considers all highly liquid debt
instruments with an initial maturity of three months or less to be cash
equivalents.

     Credit Risk Due to Certain Concentrations. The Company extends credit,
primarily in the form of monthly oil and gas sales and joint interest owners
receivables, to various companies in the oil and gas industry, which results in
a concentration of credit risk. The concentration of credit risk may be affected
by changes in economic or other conditions and may accordingly impact the
Company's overall credit risk. However, the Company believes that the risk of
these unsecured receivables is mitigated by the size, reputation, and nature of
the companies to which the Company extends credit. During 1998, oil and gas
sales to subsidiaries of PG&E Energy Trading Corporation and Aquila Southwest
Pipeline Corporation were $13.0 million (16.2% of oil and gas sales) and $8.0
million (10.0%), respectively. In 1997, oil and gas sales to PG&E Energy Trading
Corporation, Aquila Southwest Pipeline Corporation, and Koch Oil Company were
$13.5 million (19.5%), $8.1 million (11.7%), and $7.1 million (10.3%),
respectively. In 1996, oil and gas sales to TECO Gas Marketing Company were $6.9
million (13.0%).

     Fair Value of Financial Instruments. The Company's financial instruments
consist of cash and cash equivalents, accounts receivable, accounts payable,
bank borrowings, and convertible notes. The carrying amounts of cash and cash
equivalents, accounts receivable, and accounts payable approximate fair value
due to the highly liquid nature of these short-term instruments. The fair values
of the bank borrowings approximate the carrying amounts as of December 31, 1998
and 1997 and were determined based upon interest rates currently available to
the Company for borrowings with similar terms. The fair values of the
convertible notes were $81.4 million and $113.6 million at December 31, 1998 and
1997, respectively, and were based on quoted markets prices as of the respective
dates.

     New Accounting Pronouncements. In the first quarter of 1998, the Company
adopted the Statement of Financial Accounting Standards ("SFAS") No. 130,
"Reporting Comprehensive Income," which requires the display of comprehensive
income and its components in the financial statements. Comprehensive income
represents all changes in equity during the reporting period, including net
income and charges directly to equity, which are excluded from net income. The
adoption of this statement does not have a material impact on the Company or its
financial disclosures, as the Company has not historically and currently does
not enter into transactions that result in charges (or credits) directly to
equity (such as additional minimum pension liability changes, currency
translation adjustments, and unrealized gains and losses on available-for-sale
securities).

     In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities." The Statement
establishes accounting and reporting standards requiring that every derivative
instrument (including certain derivative instruments embedded in other
contracts) be recorded in the balance sheet as either an asset or liability
measured at its fair value. SFAS No. 133 requires that changes in the
derivative's fair value be recognized currently in earnings unless specific
hedge accounting criteria are met. Special accounting for qualifying hedges
allows the gains and losses on derivatives to offset related results on the
hedged item in the income statements and requires that a company must formally
document, designate, and assess the effectiveness of transactions that receive
hedge accounting. SFAS No. 133, as amended by SFAS No. 137, is effective for
fiscal years beginning after June 15, 2000. The Company is currently evaluating
the new standard, but has not yet determined the impact it will have on its
financial position and results of operations.

2. EARNINGS PER SHARE

     Basic earnings per share ("Basic EPS") has been computed using the weighted
average number of common shares outstanding during the respective periods. Basic
EPS has been retroactively restated in all periods presented to give recognition
to the 10% stock dividend declared in October 1997 that resulted in an
additional 1,494,622 shares being issued.

     The calculation of diluted earnings per share ("Diluted EPS") assumes
conversion of the Company's Convertible Notes as of the beginning of the
respective periods and the elimination of the related after-tax interest expense
and assumes, as of the beginning of the period, exercise of stock options and
warrants (using the treasury stock method). Certain of the Company's stock
options that would potentially dilute Basic EPS in the future were not included
in the computation of Diluted EPS because to do so would have been antidilutive
for the 1998 period and for the six months ended June 30, 1999 and 1998. Diluted
EPS has also been retroactively restated for all periods presented to give
effect to the 10% stock dividend. The original conversion price of the
Convertible Notes of $34.6875 was revised to $31.534 to reflect the October 1997
stock dividend declared.

     The following is a reconciliation of the numerators and denominators used
in the calculation of Basic and Diluted EPS for the years ended December 31,
1998, 1997, and 1996:

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     There are differences between income taxes computed using the statutory
rate (34% for 1998, 1997, and 1996) and the Company's effective income tax rates
(34.3%, 32.7%, and 33.9% for 1998, 1997, and 1996, respectively), primarily as
the result of certain tax credits available to the Company. Reconciliations of
income taxes computed using the statutory rate to the effective income tax rates
are as follows:

</TABLE>

     The Company did not record any valuation allowances against deferred tax
assets at December 31, 1998 or 1997.

     At December 31, 1998, the Company had alternative minimum tax credits of
$1,979,399 that carry forward indefinitely and are available to reduce future
regular tax liability to the extent they exceed the related tentative minimum
tax otherwise due.

4. LONG-TERM DEBT

     Convertible Notes. The Company's convertible notes at December 31, 1998 and
1997, consist of $115,000,000 of 6.25% Convertible Subordinated Notes due 2006.
The following description of the Convertible Notes is qualified in its entirety
by reference to the indenture for the Convertible Notes, a form of which has
been filed with the SEC.

     Payments of principal, interest and premiums, under the Convertible Notes
will be subordinated to payments on the notes and are subordinate to all other
senior debt of Swift, including its credit facilities. Holders of the
Convertible Notes may convert them into common stock at any time before maturity
at a price of $31.534 per share. This price is subject to adjustment if certain
events occur. On or after November 15, 1999, Swift may redeem the convertible
notes for cash at 104.375% of principal. This conversion is subject to
restrictions and the conversion rate declines overtime to 100.625% in 2005. If
certain Changes in Control occur, or if our common stock ceases trading on a
national exchange or automated quotation system, holders of Convertible Notes
will have the right to require us to repurchase

<PAGE>   106
                     SWIFT ENERGY COMPANY AND SUBSIDIARIES

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

the Convertible Notes at 101% of the note's principal amount, plus accrued and
unpaid interest to the date of repurchase.

     Interest expense on the Notes, including amortization of debt issuance
costs, totaled $7,544,650 and $7,514,967 in 1998 and 1997, respectively.

     Bank Borrowings. In August 1998, the Company closed its new $250.0 million
revolving credit facility with a syndicate of ten banks (the "New Credit
Facility"). At December 31, 1998, the Company had outstanding borrowings of
$146.2 million under its New Credit Facility. At December 31, 1997, the Company
had outstanding borrowings of $7.9 million under its borrowing arrangements. At
December 31, 1998, the New Credit Facility consisted of a $250.0 million
revolving line of credit with a $170.0 million borrowing base. The interest rate
is either (a) the lead bank's prime rate (7.75% at December 31, 1998) or (b) the
adjusted London Interbank Offered Rate ("LIBOR") plus the applicable margin
depending on the level of outstanding debt (a weighted average of 6.34% at
December 31, 1998). The applicable margin is based on the Company's ratio of
outstanding balance on the New Credit Facility to the last calculated borrowing
base. Of the $146.2 million borrowed at December 31, 1998, $145.0 million was
borrowed at the LIBOR rate.

     The terms of the New Credit Facility include, among other restrictions, a
limitation on the level of cash dividends (not to exceed $2.0 million in any
fiscal year), requirements as to maintenance of certain minimum financial ratios
(principally pertaining to working capital, debt, and equity ratios), and
limitations on incurring other debt. Since inception, no cash dividends have
been declared on the Company's common stock. The Company is currently in
compliance with the provisions of this agreement, as amended in mid-March 1999
to modify the cash flow-to-debt covenant. The New Credit Facility will extend
until August 2002.

     Previously, the Company's credit facilities consisted of a $100.0 million
revolving line of credit with an $80.0 million borrowing base and a $7.0 million
revolving line of credit with a $5.1 million borrowing base. These facilities
were with a two-bank group. Depending on the level of outstanding debt, the
interest rate on the $100.0 million revolving line of credit was (a) either the
bank's base rate or the bank's base rate plus 0.25% or (b) the LIBOR rate plus
1% to 1.5%. The interest rate on the $7.0 million revolving line of credit was
the bank's base rate less 0.25%.

     In addition to interest on these credit facilities, the Company pays a
commitment fee to compensate the banks for making funds available. The fee on
the revolving line of credit is calculated on the average daily remainder, if
any, of the commitment amount less the aggregate principal amounts outstanding,
plus the amount of all letters of credit outstanding during the period. The
aggregate amounts of commitment fees paid by the Company were $114,000 in 1998
and $31,000 in 1997.

5. COMMITMENTS AND CONTINGENCIES

     Total rental and lease expenses were $1,117,351 in 1998, $1,039,210 in
1997, and $957,797 in 1996. The Company's remaining minimum annual obligations
under non-cancelable operating lease commitments are $1,146,229 for 1999,
$1,151,249 for 2000, $1,151,249 for 2001, $1,273,007 for 2002, and $1,358,238
for 2003.

     As of December 31, 1998, the Company is the managing general partner of 80
limited partnerships. Because the Company serves as the general partner of these
entities, under state partnership law it is contingently liable for the
liabilities of these partnerships, which liabilities are not material for any of
the periods presented in relation to the partnerships' respective assets.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     In the ordinary course of business, the Company has been party to various
legal actions, which arise primarily from its activities as operator of oil and
gas wells. In management's opinion, the outcome of any such currently pending
legal actions will not have a material adverse effect on the financial position
or results of operations of the Company.

6. STOCKHOLDERS' EQUITY

     Common Stock. In October 1997, the Company declared a 10% stock dividend to
stockholders of record. The transaction was valued based on the closing price
($28.8125) of the Company's common stock on the New York Stock Exchange on
October 1, 1997. As a result of the issuance of 1,494,622 shares of the
Company's common stock as a dividend, retained earnings were reduced by
$43,063,796, with the common stock and additional paid-in capital accounts
increased by the same amount. Basic and Diluted EPS were restated for all
periods presented to reflect the effect of the stock dividend.

     Stock-Based Compensation Plans. The Company has two stock option plans, the
1990 stock compensation plan and the 1990 non-qualified plan, as well as an
employee stock purchase plan.

     Under the 1990 stock compensation plan, incentive stock options and other
options and awards may be granted to employees to purchase shares of common
stock. Under the 1990 non-qualified plan, non-employee members of the Company's
Board of Directors may be granted options to purchase shares of common stock.
Both plans provide that the exercise prices equal 100% of the fair value of the
common stock on the date of grant. Options become exercisable for 20% of the
shares on the first anniversary of the grant of the option and are exercisable
for an additional 20% per year thereafter. Options granted expire 10 years after
the date of grant or earlier in the event of the optionee's separation from
employment. At the time the stock options are exercised, the option price is
credited to common stock and additional paid-in capital.

     On December 9, 1998, the Company canceled certain previously issued options
under the 1990 stock compensation plan and reissued them at an option price that
reflected current market value of the Company's common stock as of that date. No
compensation expense was recognized in 1998 as a result of this transaction.

     The employee stock purchase plan provides eligible employees the
opportunity to acquire shares of Company common stock at a discount through
payroll deductions. The plan year is from June 1 to the following May 31. The
first year of the plan commenced June 1, 1993. To date, employees have been
allowed to authorize payroll deductions of up to 10% of their base salary during
the plan year by making an election to participate prior to the start of a plan
year. The purchase price for stock acquired under the plan will be 85% of the
lower of the closing price of the Company's common stock as quoted on the New
York Stock Exchange at the beginning or end of the plan year or a date during
the year chosen by the participant. Under this plan, the Company issued 20,756
shares at a price range of $13.65 to $18.06 in 1998, 26,551 shares at a price of
$15.19 in 1997, and 36,387 shares at a price range of $6.59 to $7.97 in 1996.
The estimated weighted average fair value of shares issued under this plan was
$6.86 in 1998, $4.39 in 1997, and $2.13 in 1996. As of December 31, 1998, there
remained 437,448 shares available for issuance under this plan. There are no
charges or credits to income in connection with this plan.

     The Company accounts for the two stock option plans under Accounting
Principles Board Opinion No. 25, under which no compensation expense has been
recognized. Had compensation expense for these plans been determined consistent
with SFAS No. 123, "Accounting for Stock-Based Compensation," the Company's net
income (loss) and earnings per share would have been reduced to the following
pro forma amounts (1996 amounts have been restated to reflect the October 1997
10% stock dividend):

     Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of the cost to be expected in future years.

     The fair value of each option grant, as opposed to its exercise price, is
estimated on the date of grant using the Black-Scholes option-pricing model with
the following weighted average assumptions in 1998, 1997, and 1996,
respectively: no dividend yield, expected volatility factors of 42.3%, 38.7%,
and 40.4%, risk-free interest rates of 4.69%, 6.02%, and 6.42%, and expected
lives of 7.0, 7.5, and 10.0 years. The following table summarizes information

     Employee Stock Ownership Plan. In 1996, the Company established an Employee
Stock Ownership Plan ("ESOP") effective January 1, 1996. All employees over the
age of 21 with one year of service are participants. The Plan has a five-year
cliff vesting, and service is recognized after the Plan effective date. The ESOP
is designed to enable employees of the Company to accumulate stock ownership.
While there will be no employee contributions, participants will receive an
allocation of stock that has been contributed by the Company. Compensation
expense is reported when such shares are released to employees. The Plan may
also acquire common stock of the Company purchased at fair market value. The
ESOP can borrow money from the Company to buy Company stock. This was done in
September 1996 to purchase 25,000 shares (adjusted to 27,500 shares after the
October 1, 1997, 10% stock dividend) from the Company's chairman. Benefits will
be paid in a lump sum or installments, and the participants generally have the
choice of receiving cash or stock. At December 31, 1998, all of the ESOP
compensation was earned. At December 31, 1997 and 1996, the unearned portions of
the ESOP, $150,055 and $521,354, respectively, were recorded as a contra-equity
account entitled "Unearned ESOP Compensation."

     Common Stock Repurchase Program. In March 1997, the Company's Board of
Directors approved a common stock repurchase program for up to $20.0 million of
the Company's common stock and subsequently extended this program through June
30, 1998. Under this program, the Company used approximately $9.3 million of
working capital to acquire 435,274 shares in the open market at an average cost
of $21.47 per share. On July 23, 1998, the Board of Directors approved a new
repurchase program for up to $10.0 million of the Company's common stock through
the end of 1998. Subsequently, the Company used approximately $2.5 million of
working capital to acquire another 246,001 shares for an average cost of $10.14
per share. Through December 31, 1998, 681,275 shares have been acquired at a
total cost of $11,841,884 and are included in "Treasury stock held, at cost" on
the balance sheet.

     Shareholder Rights Plan. In August 1997, the Board of Directors declared a
dividend of one preferred share purchase right on each outstanding share of the
Company's common stock. The rights are not currently exercisable but would
become exercisable if certain events occurred relating to any person or group
acquiring or attempting to acquire 15% or more of the Company's outstanding
shares of common stock. Thereafter, upon certain triggers, each right not owned
by an acquirer allows its holder to purchase Company securities with a market
value of two times the $150 exercise price.

7. RELATED-PARTY TRANSACTIONS

     The Company is the operator of a substantial number of properties owned by
its affiliated limited partnerships and joint ventures and accordingly, charges
these entities and third-party joint interest owners operating fees. The Company
is also reimbursed for direct, administrative, and overhead costs incurred in
conducting the business of the limited partnerships, which totaled approximately
$5,000,000, $6,300,000,

                                      F-17

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

and $6,100,000 in 1998, 1997, and 1996, respectively. The Company was also
reimbursed by the limited partnerships and joint ventures for costs incurred in
the screening, evaluation, and acquisition of producing oil and gas properties
on their behalf. Such costs totaled approximately $490,000 and $250,000 in 1997
and 1996, respectively. The Company, with the acquisitions made in 1997, has
fulfilled its responsibility of acquiring properties for such partnerships, as
those partnerships are fully invested in properties. In the case where the
limited partners voted to sell their remaining properties and liquidate their
limited partnerships, the Company was also reimbursed for direct,
administrative, and overhead costs incurred in the disposition of such
properties, which costs totaled approximately $580,000, $675,000, and $805,000
in 1998, 1997, and 1996, respectively.

     The ESOP can borrow money from the Company to buy Company stock. This was
done in September 1996 to purchase 25,000 shares (adjusted to 27,500 shares
after the October 1, 1997 10% stock dividend) from the Company's chairman.
Benefits will be paid in a lump sum or installments, and the participants
generally have the choice of receiving cash or stock.

8. FOREIGN ACTIVITIES

     New Zealand. Since October 1995, the Company has been issued two Petroleum
Exploration Permits by the New Zealand Minister of Energy. The first permit
covered approximately 65,000 acres in the Onshore Taranaki Basin of New
Zealand's North Island, and the second covered approximately 69,300 adjacent
acres. A wholly owned subsidiary, Swift Energy New Zealand Limited, formed in
late 1997, conducts the Company's New Zealand activities and owns the interest
in the permits. In March 1998, the Company surrendered approximately 46,400
acres covered in the first permit, and the remaining acreage has been included
as an extension of the area covered in the second permit. Under the terms of the
expanded permit, the Company is obligated to drill one exploratory well prior to
August 12, 1999. All other obligations under the permit have been fulfilled,
including the reinterpretation of existing seismic data and the acquisition and
processing of new seismic data.

     On October 23, 1998, the Company entered into separate agreements with
Marabella Enterprises Ltd. ("Marabella"), a subsidiary of Bligh Oil & Minerals
N.L., an Australian company, to obtain from Marabella a 25% working interest in
another New Zealand Petroleum Exploration Permit and for Marabella to become a
5% participant in the Company's permit. An exploration well on the Marabella
permit commenced drilling on October 16, 1998, the results of which were
unsuccessful. Accordingly, the $0.4 million costs of such well were charged
against earnings. The Company has also agreed in principle to participate with
Marabella in an additional permit as a 17.5% working interest owner.

     At December 31, 1998, the Company's investment in New Zealand was
approximately $5.0 million and is included in the unproved properties portion of
oil and gas properties. Approximately $0.4 million of such costs have been
impaired.

     Russia. On September 3, 1993, the Company signed a Participation Agreement
with Senega, a Russian Federation joint stock company (in which the Company has
an indirect interest of less than 1%), to assist in the development and
production of reserves from two fields in Western Siberia, providing the Company
with a minimum 5% net profits interest from the sale of hydrocarbon products
from the fields for providing managerial, technical, and financial support to
Senega. Additionally, the Company purchased a 1% net profits interest from
Senega for $0.3 million.

     On December 10, 1997, the Company amended and restated the Participation
Agreement. Under the amended and restated Participation Agreement, the Company
retains its 6% net profits interest in the Samburg Field and agreed to assist
Senega in obtaining investments necessary to develop the field. Senega is
charged with the management and control of the field development. The Company's
investment in Russia, prior to its impairment in the third quarter of 1998, was
approximately $10.8 million and was

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

previously included in the unproved properties portion of oil and gas
properties. However, the economic and political uncertainty and currency
concerns that arose during the third quarter of 1998 in Russia, combined with
the price volatility and severe tightening of international capital markets,
caused the Company to re-evaluate the timing of the recovery of its capitalized
costs in that country. See Note 1 to the Company's financial statements for a
more detailed discussion of the impairment. Subsequent to such impairment, any
costs incurred in Russia have been reported as a charge to earnings.

     Venezuela. The Company formed a wholly owned subsidiary, Swift Energy de
Venezuela, C. A., for the purpose of submitting a bid on August 5, 1993, under
the Venezuelan Marginal Oil Field Reactivation Program. Although the Company did
not win the bid, it has continued to gather information relating to reserves and
geological and geophysical data in Venezuela, and continued to pursue
cooperative ventures involving other fields and opportunities in Venezuela. The
Company evaluated a number of blocks being offered by Petroleos de Venezuela, S.
A. under the Third Operating Agreement Round in 1997, but decided against
submitting any bid on these blocks. The Company has entered into an agreement
with Tecnoconsult, S. A., and Corporation EDC, S.A.C.A., Venezuelan companies,
to jointly formulate and submit a proposal to Petroleos de Venezuela, S. A. for
the construction and operation of a methane pipeline. Currently, the technical
and economic feasibility of the project is under study. The Company's investment
in Venezuela, prior to its impairment in the third quarter of 1998, was
approximately $2.8 million and was previously included in the unproved
properties portion of oil and gas properties. However, the economic uncertainty
and currency concerns in Venezuela, combined with the price volatility and
severe tightening of international capital markets, caused the Company to
re-evaluate its prospects of participating in further Venezuelan exploration
activities in the near-term and the prospects for recovery of its capitalized
costs in that country. See Note 1 to the Company's financial statements for a
more detailed discussion of the impairment. Subsequent to such impairment, any
costs incurred in Venezuela have been reported as a charge to earnings.

9. ACQUISITION OF PROPERTIES

     In the third quarter of 1998, the Company purchased from Sonat Exploration
Company ("Sonat"), a subsidiary of Sonat Inc., the Toledo Bend Properties
located in Texas and Louisiana in the vicinity of Toledo Bend Lake for
approximately $87.0 million in cash, with approximately $56.8 million of the
total spent for producing properties, approximately $15.0 million to purchase an
interest in two gas processing plants, and approximately $15.2 million to
acquire leasehold properties. Post-closing purchase price adjustments are still
being determined, but management does not expect that these adjustments will be
material to the Company's financial statements.

     As of December 31, 1998, estimated proved reserves for the Toledo Bend
Properties were 130.5 Bcfe, of which approximately 58% was natural gas, and 59%
was proved undeveloped. At such date the properties include 162 producing oil
and natural gas wells in the Brookeland Field in Southeast Texas and the Masters
Creek Field in Western Louisiana, 23 saltwater disposal wells, a 20% interest in
two natural gas plants, associated production facilities, working interests in
approximately 200,875 gross undeveloped (125,378 net undeveloped) acres, and
approximately 114,000 undeveloped fee mineral acres. The Company has become
operator of 115 of the 162 wells. The two gas plants are operated by a third
party and have combined capacity of 250 MMcfe per day.

     The Toledo Bend Properties extend one of the Company's core areas by adding
producing reserves that the Company believes will significantly increase its
production on a short-term basis. The Company's production on these properties
amounted to approximately 11.6 Bcfe, of which 44% was natural gas. Furthermore,
as a result of the Company's extensive experience in other parts of the Austin
Chalk trend, the Company believes that it can successfully exploit incremental
drilling opportunities in the future.

</TABLE>

     Of the $51,040,378 of domestic unproved property costs (primarily seismic
and lease acquisition costs) at December 31, 1998, excluded from the amortizable
base, $33,360,518 was incurred in 1998, $11,966,626 was incurred in 1997,
$3,260,112 was incurred in 1996, and $2,953,122 was incurred in prior years.
When the Company is in an active drilling mode, it has evaluated the majority of
these unproved costs within a two to three year time frame. In response to
current market conditions, the Company has decreased its planned 1999 drilling
expenditures when compared to recent years, which when coupled with the $15.2
million of leasehold properties acquired in the Toledo Bend Properties
acquisition may extend the evaluation timeframe of such costs.

     Of the $5,001,508 of net foreign unproved property costs at December 31,
1998, being excluded from the amortizable base, $2,521,761 was incurred in 1998,
$1,731,561 was incurred in 1997, $545,980 was incurred in 1996, and $202,206 was
incurred in 1995. All of these costs are costs incurred in New Zealand, as the
costs incurred in Russia and Venezuela were impaired in the third quarter of
1998 (see Note 1 to the Company's financial statements). The Company expects it
will complete its evaluation of the New Zealand properties as wells are drilled
over the next two to three years.

(1) Proved reserves exclude quantities subject to the Company's volumetric
    production payment agreement.

(2) Revisions of previous estimates are related to upward or downward variations
    based on current engineering information for production rates, volumetrics,
    and reservoir pressure. Additionally, changes in quantity estimates are
    affected by the increase or decrease in crude oil and natural gas prices at
    each year end. Proved reserves, as of December 31, 1998, were based upon
    prices of $2.23 per Mcf of natural gas and $11.23 per barrel of oil,
    compared to $2.78 per Mcf and $15.76 per barrel as of December 31, 1997.

(3) Natural gas production for 1996, 1997, and 1998 excludes 1,156,361,
    1,015,226, and 866,232 Mcf, respectively, delivered under the Company's
    volumetric production payment agreement.

</TABLE>

     The standardized measure of discounted future net cash flows from
production of proved reserves was developed as follows:

          1. Estimates are made of quantities of proved reserves and the future
     periods during which they are expected to be produced based on year-end
     economic conditions.

          2. The estimated future gross revenues of proved reserves are priced
     on the basis of year-end prices, except in those instances where fixed and
     determinable gas price escalations are covered by contracts limited to the
     price the Company reasonably expects to receive.

          3. The future gross revenue streams are reduced by estimated future
     costs to develop and to produce the proved reserves, as well as certain
     abandonment costs based on year-end cost estimates and the estimated effect
     of future income taxes.

          4. Future income taxes are computed by applying the statutory tax rate
     to future net cash flows reduced by the tax basis of the properties, the
     estimated permanent differences applicable to future oil and gas producing
     activities, and tax carry forwards.

     The estimates of cash flows and reserves quantities shown above are based
on year-end oil and gas prices for each period. Under Securities and Exchange
Commission rules, companies that follow the full-cost accounting method are
required to make quarterly Ceiling Test calculations, using prices in effect as
of the period end date presented (see Note 1). Application of these rules during
periods of relatively low oil and gas prices, even if of short-term seasonal
duration, may result in write-downs.

     The standardized measure of discounted future net cash flows is not
intended to present the fair market value of the Company's oil and gas property
reserves. An estimate of fair value would also take into account, among other
things, the recovery of reserves in excess of proved reserves, anticipated
future changes in prices and costs, an allowance for return on investment, and
the risks inherent in reserve estimates.

                           FORWARD-LOOKING STATEMENTS

     Some of the information included in this prospectus, any prospectus
supplement and the documents we have incorporated by reference contain
forward-looking statements. Forward-looking statements use forward-looking terms
such as "believe," "expect," "may," "intend," "will," "project," "budget,"
"should" or "anticipate" or other similar words. These statements discuss
"forward-looking" information such as:

        - anticipated capital expenditures and budgets;

        - future cash flows and borrowings;

        - pursuit of potential future acquisition or drilling opportunities; and

        - sources of funding for exploration and development.

     These forward-looking statements are based on assumptions that we believe
are reasonable, but they are open to a wide range of uncertainties and business
risks, including the following:

        - fluctuations of the prices received or demand for oil and natural gas;

        - uncertainty of drilling results, reserve estimates and reserve
          replacement;

        - operating hazards;

        - acquisition risks;

        - unexpected substantial variances in capital requirements;

        - environmental matters;

        - our year 2000 compliance program; and

        - general economic conditions.

     Other factors that could cause actual results to differ materially from
those anticipated are discussed in our periodic filings with the SEC, including
our Annual Report on Form 10-K for the year ended December 31, 1998.

     When considering these forward-looking statements, you should keep in mind
the risk factors and other cautionary statements in this prospectus, any
prospectus supplement and the documents we have incorporated by reference. We
will not update these forward-looking statements unless the securities laws
require us to do so.

                                  THE COMPANY

     Swift Energy Company, a Texas corporation, is engaged in the exploration,
development, acquisition and operation of oil and gas properties. Our primary
focus is on U.S. onshore natural gas reserves. As of December 31, 1998, we had
interests in over 1,750 oil and gas wells located in eight states. We operated
836 of these wells, representing 91% of our proved reserves base. At such date,
our estimated proved reserves were 436.1 Bcfe, of which approximately 81% was
natural gas, with 84% of our reserves located in Texas and 13% in Louisiana.

     Our core areas for development and exploration drilling are the AWP Olmos
Field located in South Texas and the Austin Chalk trend in Texas and Louisiana.
We expect the reserves on the AWP Olmos Field to be steadily produced over a
long period. This offsets the Austin Chalk trend reserves, which have a high
initial production but decline rapidly. The AWP Olmos Field accounted for
approximately 51% of our proved reserves as of December 31, 1998 and
approximately 40% of our 1998 production, while the Austin Chalk trend accounted
for approximately 42% of our proved reserves as of December 31, 1998 and
generated approximately 48% of our 1998 production.

                                        4
<PAGE>   122

     We have increased our proved reserves from 90.1 Bcfe at year-end 1993 to
436.1 Bcfe at year-end 1998, which represents the replacement of 449% of the
production during the same period. Our five-year average reserves replacement
costs were $0.88 per Mcfe. The combination of increased production and decreased
operating costs per Mcfe resulted in average annual growth in net cash provided
by operating activities of 50% per year from 1993 to 1998.

     Swift's philosophy is to pursue a balanced growth strategy that includes an
active drilling program, strategic acquisitions, and the utilization of advanced
technologies. We seek to increase our reserves through both drilling and
acquisitions, shifting the balance between the two activities in response to
market conditions. For example, when oil and gas prices are low, we focus upon
acquiring producing properties. When oil and gas prices are high, we shift our
focus to drilling wells.

     Over the last several years, we have grown primarily by increasing our
acreage position and through drilling activities in the AWP Olmos Field and the
Austin Chalk trend. Capital expenditures for development and exploration
drilling were $71.8 million in 1996 and $101.0 million in 1997, while the
amounts spent for acquisitions were $1.5 million in 1996 and $8.4 million in
1997. Following the fall in oil and gas prices during mid-1998, we decreased
amounts spent for drilling and increased funds spent to acquire producing
properties, primarily the Toledo Bend Properties in Texas and Louisiana
purchased from Sonat Exploration Company. Consequently, in 1998 drilling
expenditures were concentrated in the first half of 1998, totaling $67.4
million, while $59.5 million was spent to acquire producing properties,
primarily in the third quarter.

     Our principal executive offices are located at 16825 Northchase Drive,
Suite 400, Houston, Texas 77060, and our telephone number is (281) 874-2700.

                       RATIO OF EARNINGS TO FIXED CHARGES

     The following table sets forth our ratio of earnings to fixed charges:

                                                                                     THREE MONTHS

Ratio of earnings to fixed charges.............  2.6x   3.1x   12.8x   5.2x    --    2.9x    1.3x
</TABLE>

     Due to the $90.8 million non-cash charge incurred in the year ended
December 31, 1998 caused by a write down in the carrying value of natural gas
and oil properties, 1998 earnings were insufficient by $76.9 million to cover
fixed charges in 1998. If the $90.8 million non-cash charge is excluded, the
ratio of earnings to fixed charges would have been 2.1x.

     For the purpose of computing the ratio of earnings to fixed charges,
earnings are defined as:

        - income from continuing operations before income taxes;

        - plus fixed charges; and

        - less capitalized interest.

     Fixed charges are defined as the sum of the following:

        - interest, including capitalized interest, on all indebtedness;

        - amortization of debt issuance cost; and

        - that portion of rental expense which we believe to be representative
          of an interest factor.

                                USE OF PROCEEDS

     Unless we specify otherwise in an accompanying prospectus supplement, we
intend to use the net proceeds we receive from the sale of securities offered by
this prospectus and the accompanying prospectus supplement for the repayment of
debt under our credit lines and for general corporate purposes. General
corporate purposes may include additions to working capital, development and
exploration expenditures or the financing of possible acquisitions.

     The net proceeds may be invested temporarily until they are used for their
stated purpose.

                         DESCRIPTION OF DEBT SECURITIES

     This section describes the general terms and provisions of the debt
securities which may be offered by us from time to time. The applicable
prospectus supplement will describe the specific terms of the debt securities
offered by that prospectus supplement.

     We may issue debt securities either separately or together with, or upon
the conversion of, or in exchange for, other securities. The debt securities are
to be either senior obligations of ours issued in one or more series and
referred to herein as the "Senior Debt Securities," or subordinated obligations
of ours issued in one or more series and referred to herein as the "Subordinated
Debt Securities." The Senior Debt Securities and the Subordinated Debt
Securities are collectively referred to as the "Debt Securities." The Debt
Securities will be general obligations of the Company. Each series of Debt
Securities will be issued under an agreement, or "Indenture," between Swift and
an independent third party, usually a bank or trust company, known as a
"Trustee," who will be legally obligated to carry out the terms of the
Indenture. The name(s) of the Trustee(s) will be set forth in the applicable
prospectus supplement. We may issue all the Debt Securities under the same
Indenture, as one or as separate series, as specified in the applicable
prospectus supplement(s).

     This summary of certain terms and provisions of the Debt Securities and
Indentures is not complete. If we refer to particular provisions of an
Indenture, the provisions, including definitions of certain terms, are
incorporated by reference as a part of this summary. The Indentures are or will
be filed as an exhibit to the registration statement of which this prospectus is
a part, or as exhibits to documents filed under the Securities Exchange Act of
1934 which are incorporated by reference into this prospectus. The Indentures
are subject to and governed by the Trust Indenture Act of 1939, as amended. You
should refer to the applicable Indenture for the provisions which may be
important to you.

GENERAL

     The Indentures will not limit the amount of Debt Securities which we may
issue. We may issue Debt Securities up to an aggregate principal amount as we
may authorize from time to time. The applicable prospectus supplement will
describe the terms of any Debt Securities being offered, including:

        - the title and aggregate principal amount;

        - the date(s) when principal is payable;

        - the interest rate, if any, and the method for calculating the interest
          rate;

        - the interest payment dates and the record dates for the interest
          payments;

        - the places where the principal and interest will be payable;

        - any mandatory or optional redemption or repurchase terms or
          prepayment, conversion, sinking fund or exchangeability or
          convertibility provisions;

        - whether such Debt Securities will be Senior Debt Securities or
          Subordinated Debt Securities and, if Subordinated Debt Securities, the
          subordination provisions and the applicable definition of "Senior
          Indebtedness";

                                        6
<PAGE>   124

        - additional provisions, if any, relating to the defeasance and covenant

          Securities, as defined below, or certificates;

        - other specific terms, including covenants and any additions or changes
          to the events of default provided for with respect to the Debt
          Securities.

     The terms of the Debt Securities of any series may differ and, without the
consent of the holders of the Debt Securities of any series, we may reopen a
previous series of Debt Securities and issue additional Debt Securities of such
series or establish additional terms of such series, unless otherwise indicated
in the applicable prospectus supplement.

NON U.S. CURRENCY

     If the purchase price of any Debt Securities is payable in a currency other
than U.S. dollars or if principal of, or premium, if any, or interest, if any,
on any of the Debt Securities is payable in any currency other than U.S.
dollars, the specific terms with respect to such Debt Securities and such
foreign currency will be specified in the applicable prospectus supplement.

ORIGINAL ISSUE DISCOUNT SECURITIES

     Debt Securities may be issued as "Original Issue Discount Securities" to be
sold at a substantial discount below their principal amount. Original Issue
Discount Securities may include "zero coupon" securities that do not pay any
cash interest for the entire term of the securities. In the event of an
acceleration of the maturity of any Original Issue Discount Security, the amount
payable to the holder thereof upon such acceleration will be determined in the
manner described in the applicable prospectus supplement. Conditions pursuant to
which payment of the principal of the Subordinated Debt Securities may be
accelerated will be set forth in the applicable prospectus supplement. Material
federal income tax and other considerations applicable to Original Issue
Discount Securities will be described in the applicable prospectus supplement.

                                        7
<PAGE>   125

COVENANTS

     Under the Indentures, we will be required to:

        - 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 paying agent on or before the due
          date for any principal, interest or any premium.

     Any additional covenants will be described in the applicable prospectus
supplement.

REGISTRATION, TRANSFER, PAYMENT AND PAYING AGENT

     Unless otherwise indicated in a prospectus supplement, each series of Debt
Securities will be issued in registered form only, without coupons. The
Indentures, however, provide that we may also issue Debt Securities in bearer
form only, or in both registered and bearer form. Bearer Securities shall not be
offered, sold, resold or delivered in connection with their original issuance in
the United States or to any United States person other than offices located
outside the United States of certain United States financial institutions.
"United States person" means any citizen or resident of the United States, any
corporation, partnership or other entity created or organized in or under the
laws of the United States, any estate the income of which is subject to United
States federal income taxation regardless of its source, or any trust whose
administration is subject to the primary supervision of a United States court
and which has one or more United States fiduciaries who have the authority to
control all substantial decisions of the trust. "United States" means the United
States of America (including the states thereof and the District of Columbia),
its territories, its possessions and other areas subject to its jurisdiction.
Purchasers of Bearer Securities will be subject to certification procedures and
may be affected by certain limitations under United States tax laws. Such
procedures and limitations will be described in the prospectus supplement
relating to the offering of the Bearer Securities.

     Unless otherwise indicated in a prospectus supplement, Registered
Securities will be issued in denominations of $1,000 or any integral multiple
thereof, and Bearer Securities will be issued in denominations of $5,000.

     Unless otherwise indicated in a prospectus supplement, the principal,
premium, if any, and interest, if any, of or on the Debt Securities will be
payable, and Debt Securities may be surrendered for registration of transfer or
exchange, at an office or agency to be maintained by us in the Borough of
Manhattan, The City of New York, provided that payments of interest with respect
to any Registered Security may be made at our option by check mailed to the
address of the person entitled to payment or by transfer to an account
maintained by the payee with a bank located in the United States. No service
charge shall be made for any registration of transfer or exchange of Debt
Securities, but we may require payment of a sum sufficient to cover any tax or
other governmental charge and any other expenses that may be imposed in
connection with the exchange or transfer.

     Unless otherwise indicated in a prospectus supplement, payment of principal
of, premium, if any, and interest, if any, on Bearer Securities will be made,
subject to any applicable laws and regulations, at such office or agency outside
the United States as specified in the prospectus supplement and as we may
designate from time to time. Unless otherwise indicated in a prospectus
supplement, payment of interest due on Bearer Securities on any interest payment
date will be made only against surrender of the coupon relating to such interest
payment date. Unless otherwise indicated in a prospectus supplement, no payment
of principal, premium or interest with respect to any Bearer Security will be
made at any office or agency in the United States or by check mailed to any
address in the United States or by transfer to an account maintained with a bank
located in the United States; except that if amounts owing with respect to any

                                        8
<PAGE>   126

Bearer Securities shall be payable in U.S. dollars, payment may be made at the
Corporate Trust Office of the applicable Trustee or at any office or agency
designated by us in the Borough of Manhattan, The City of New York, if (but only
if) payment of the full amount of such principal, premium or interest at all
offices outside of the United States maintained for such purpose by us is
illegal or effectively precluded by exchange controls or similar restrictions.

     Unless otherwise indicated in the applicable prospectus supplement, we will
not be required to:

        - issue, register the transfer of or exchange Debt Securities of any
          series during a period beginning at the opening of business 15 days
          before any selection of Debt Securities of that series of like tenor
          to be redeemed and ending at the close of business on the day of that
          selection;

        - register the transfer of or exchange any Registered Security, or
          portion thereof, called for redemption, except the unredeemed portion
          of any Registered Security being redeemed in part;

        - exchange any Bearer Security called for redemption, except to exchange
          such Bearer Security for a Registered Security of that series and like
          tenor that is simultaneously surrendered for redemption; or

        - issue, register the transfer of or exchange any Debt Security which
          has been surrendered for repayment at the option of the holder, except
          the portion, if any, of the Debt Security not to be so repaid.

RANKING OF DEBT SECURITIES

     The Senior Debt Securities will be unsubordinated obligations of ours and
will rank equally in right of payment with all other unsubordinated indebtedness
of ours. The Subordinated Debt Securities will be obligations of ours and will
be subordinated in right of payment to all existing and future Senior
Indebtedness. The prospectus supplement will describe the subordination
provisions and set forth the definition of "Senior Indebtedness" applicable to
the Subordinated Debt Securities, and will set forth the approximate amount of
such Senior Indebtedness outstanding as of a recent date.

GLOBAL SECURITIES

     The Debt Securities of a series may be issued in whole or in part in the
form of one or more global securities that will be deposited with, or on behalf
of, a "Depositary" identified in the prospectus supplement relating to such
series. Global Debt Securities may be issued in either registered or bearer form
and in either temporary or permanent form. Unless and until it is exchanged in
whole or in part for individual certificates evidencing Debt Securities, a
Global Debt Security may not be transferred except as a whole:

        - by the Depositary to a nominee of such Depositary;

        - by a nominee of such Depositary to such Depositary or another nominee
          of such Depositary; or

        - by such Depositary or any such nominee to a successor of such
          Depositary or a nominee of such successor.

     The specific terms of the depositary arrangement with respect to a series
of Global Debt Securities and certain limitations and restrictions relating to a
series of Global Bearer Securities will be described in the applicable
prospectus supplement.

                                        9
<PAGE>   127

OUTSTANDING DEBT SECURITIES

     In determining whether the holders of the requisite principal amount of
outstanding Debt Securities have given any authorization, demand, direction,
notice, consent or waiver under the relevant Indenture, the amount of
outstanding Debt Securities will be calculated based on the following:

        - the portion of the principal amount of an Original Issue Discount
          Security that shall be deemed to be outstanding for such purposes
          shall be that portion of the principal amount thereof that could be
          declared to be due and payable upon a declaration of acceleration
          pursuant to the terms of such Original Issue Discount Security as of
          the date of such determination;

        - the principal amount of a Debt Security denominated in a currency
          other than U.S. dollars shall be the U.S. dollar equivalent,
          determined on the date of original issue of such Debt Security, of the
          principal amount of such Debt Security; and

        - any Debt Security owned by us or any obligor on such Debt Security or
          any affiliate of us or such other obligor shall be deemed not to be
          outstanding.

REDEMPTION AND REPURCHASE

     The Debt Securities may be redeemable at our option, may be subject to
mandatory redemption pursuant to a sinking fund or otherwise, or may be subject
to repurchase by Swift at the option of the holders, in each case upon the
terms, at the times and at the prices set forth in the applicable prospectus
supplement.

CONVERSION AND EXCHANGE

     The terms, if any, on which Debt Securities of any series are convertible
into or exchangeable for common stock, preferred stock, or other Debt Securities
will be set forth in the applicable prospectus supplement. Such terms of
conversion or exchange may be either mandatory, at the option of the holders, or
at our option.

CONSOLIDATION, MERGER AND SALE OF ASSETS

     Each Indenture generally will permit a consolidation or merger, subject to
certain limitations and conditions, between us and another corporation. They
also will permit the sale by us of all or substantially all of our property and
assets. If this happens, the remaining or acquiring corporation shall 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.

     We are only permitted to consolidate or merge with or into any other
corporation or sell all or substantially all of our assets according to the
terms and conditions of the Indentures, as indicated in the applicable
prospectus supplement. The remaining or acquiring corporation 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 corporation 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 corporation.

EVENTS OF DEFAULT

     Unless otherwise specified in the applicable prospectus supplement, an
Event of Default, as defined in the Indentures and applicable to Debt Securities
issued under such Indentures, typically will occur with respect to the Debt
Securities of any series under the Indenture upon:

        - default for a period to be specified in the applicable prospectus
          supplement in payment of any interest with respect to any Debt
          Security of such series;

                                       10
<PAGE>   128

        - default in payment of principal or any premium with respect to any
          Debt Security of such series when due upon maturity, redemption,
          repurchase at the option of the holder or otherwise;

        - default in deposit of any sinking fund payment when due with respect
          to any Debt Security of such series;

        - default by us in the performance, or breach, of any other covenant or
          warranty in such Indenture, which shall not have been remedied for a
          period to be specified in the applicable prospectus supplement after
          notice to us by the applicable Trustee or the holders of not less than
          a fixed percentage in aggregate principal amount of the Debt
          Securities of all series issued under the applicable Indenture;

        - certain events of bankruptcy, insolvency or reorganization of Swift;
          or

        - any other Event of Default that may be set forth in the applicable
          prospectus supplement, including an Event of Default based on other
          debt being accelerated, known as a "cross-acceleration."

     No Event of Default with respect to any particular series of Debt
Securities necessarily constitutes an Event of Default with respect to any other
series of Debt Securities. If the Trustee considers it in the interest of the
holders to do so, the Trustee under an Indenture may withhold notice of the
occurrence of a default with respect to the Debt Securities to the holders of
any series outstanding, except a default in payment of principal, premium, if
any, interest, if any.

     Each Indenture will provide that if an Event of Default with respect to any
series of Debt Securities issued thereunder shall have occurred and be
continuing, either the relevant Trustee or the holders of at least a fixed
percentage in principal amount of the Debt Securities of such series then
outstanding may declare the principal amount of all the Debt Securities of such
series to be due and payable immediately. In the case of Original Issue Discount
Securities, the Trustee may declare as due and payable such lesser amount as may
be specified in the applicable prospectus supplement. However, upon certain
conditions, such declaration and its consequences may be rescinded and annulled
by the holders of at least a fixed percentage in principal amount of the Debt
Securities of all series issued under the applicable Indenture.

     The applicable prospectus supplement will provide the terms pursuant to
which an Event of Default shall result in acceleration of the payment of
principal of Subordinated Debt Securities.

     In the case of a default in the payment of principal of, or premium, if
any, or interest, if any, on any Subordinated Debt Securities of any series, the
applicable Trustee, subject to certain limitations and conditions, may institute
a judicial proceeding for the collection thereof.

     No holder of any of the Debt Securities of any series will have any right
to institute any proceeding with respect to the Indenture or any remedy
thereunder, unless the holders of at least a fixed percentage in principal
amount of the outstanding Debt Securities of such series:

        - have made written request to the Trustee to institute such proceeding
          as Trustee, and offered reasonable indemnity to the Trustee;

        - the Trustee has failed to institute such proceeding within the time
          period specified in the applicable prospectus supplement after receipt
          of such notice; and

        - the Trustee has not within such period received directions
          inconsistent with such written request by holders of a majority in
          principal amount of the outstanding Debt Securities of such series.
          Such limitations do not apply, however, to a suit instituted by a
          holder of a Debt Security for the enforcement of the payment of the
          principal of, premium, if any, or any accrued and unpaid interest on,
          the Debt Security on or after the respective due dates expressed in
          the Debt Security.

                                       11
<PAGE>   129

     During the existence of an Event of Default under an Indenture, the Trustee
is required to exercise such rights and powers vested in it under the Indenture
and use the same degree of care and skill in its exercise thereof as a prudent
person would exercise under the circumstances in the conduct of such person's
own affairs. Subject to the provisions of the Indenture relating to the duties
of the Trustee, if an Event of Default shall occur and be continuing, the
Trustee is under no obligation to exercise any of its rights or powers under the
Indenture at the request or direction of any of the holders, unless such holders
shall have offered to the Trustee reasonable security or indemnity. Subject to
certain provisions concerning the rights of the Trustee, the holders of at least
a fixed percentage in principal amount of the outstanding Debt Securities of any
series have the right to direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any power
conferred on the Trustee with respect to such series.

     The Indentures provide that the Trustee will, within the time period
specified in the applicable prospectus supplement after the occurrence of any
default, give to the holders of the Debt Securities of such series notice of
such default known to it, unless such default shall have been cured or waived;
provided that the Trustee shall be protected in withholding such notice if it
determines in good faith that the withholding of such notice is in the interest
of such holders, except in the case of a default in payment of principal of or
premium, if any, on any Debt Security of such series when due or in the case of
any default in the payment of any interest on the Debt Securities of such
series.

     Swift is required to furnish to the Trustee annually a statement as to
compliance with all conditions and covenants under the Indentures.

MODIFICATION AND WAIVERS

     From time to time, when authorized by resolutions of our board of directors
and by the Trustee, without the consent of the holders of Debt Securities of any
series, we may amend, waive or supplement the Indentures and the Debt Securities
of such series for certain specified purposes, including, among other things:

        - to cure ambiguities, defects or inconsistencies;

        - to provide for the assumption of our obligations to holders of the
          Debt Securities of such series in the case of a merger or
          consolidation;

        - to add to our Events of Default or our covenants or to make any change
          that would provide any additional rights or benefits to the holders of
          the Debt Securities of such series;

        - to add or change any provisions of such Indenture to facilitate the
          issuance of Bearer Securities;

        - to establish the form or terms of Debt Securities of any series and
          any related coupons;

        - to add guarantors with respect to the Debt Securities of such series;

        - to secure the Debt Securities of such series;

        - to maintain the qualification of the Indenture under the Trust
          Indenture Act; or

        - to make any change that does not adversely affect the rights of any
          holder.

     Other amendments and modifications of the Indentures or the Debt Securities
issued thereunder may be made by Swift and the Trustee with the consent of the
holders of not less than a fixed percentage of the aggregate principal amount of
the outstanding Debt Securities of each series affected, with each series voting
as a separate class; provided that, without the consent of the holder of each
outstanding Debt Security affected, no such modification or amendment may:

        - reduce the principal amount of, or extend the fixed maturity of the
          Debt Securities, or alter or waive any redemption, repurchase or
          sinking fund provisions of the Debt Securities;

                                       12
<PAGE>   130

        - reduce the amount of principal of any Original Issue Discount
          Securities that would be due and payable upon an acceleration of the
          maturity thereof;

        - change the currency in which any Debt Securities or any premium or the
          accrued interest thereon is payable;

        - reduce the percentage in principal amount outstanding of Debt
          Securities of any series which must consent to an amendment,
          supplement or waiver or consent to take any action under the Indenture
          or the Debt Securities of such series;

        - impair the right to institute suit for the enforcement of any payment
          on or with respect to the Debt Securities;

        - waive a default in payment with respect to the Debt Securities or any
          guarantee;

        - reduce the rate or extend the time for payment of interest on the Debt
          Securities;

        - adversely affect the ranking of the Debt Securities of any series;

        - release any guarantor from any of its obligations under its guarantee
          or the Indenture, except in compliance with the terms of the
          Indenture; or

        - solely in the case of a series of Subordinated Debt Securities, modify
          any of the applicable subordination provisions or the applicable
          definition of Senior Indebtedness in a manner adverse to any holders.

     The holders of a fixed percentage in aggregate principal amount of the
outstanding Debt Securities of any series may waive compliance by us with
certain restrictive provisions of the relevant Indenture, including any set
forth in the applicable prospectus supplement. The holders of a fixed percentage
in aggregate principal amount of the outstanding Debt Securities of any series
may, on behalf of the holders of that series, waive any past default under the
applicable Indenture with respect to that series and its consequences, except a
default in the payment of the principal of, or premium, if any, or interest, if
any, on any Debt Securities of such series, or in respect of a covenant or
provision which cannot be modified or amended without the consent of a larger
fixed percentage of holders or by the holder of each outstanding Debt Securities
of the series affected.

DISCHARGE, TERMINATION AND COVENANT TERMINATION

     When we establish a series of Debt Securities, we may provide that such
series is subject to the termination and discharge provisions of the applicable
Indenture. If those provisions are made applicable, we may elect either:

        - to terminate and be discharged from all of our obligations with
          respect to those Debt Securities subject to some limitations; or

        - to be released from our obligations to comply with specified covenants
          relating to those Debt Securities, as described in the applicable
          prospectus supplement.

     To effect that termination or covenant termination, we must irrevocably
deposit in trust with the relevant Trustee an amount which, through the payment
of principal and interest in accordance with their terms, will provide money
sufficient to make payments on those Debt Securities and any mandatory sinking
fund or similar payments on those Debt Securities. This deposit may be made in
any combination of funds or government obligations. On such a termination, we
will not be released from certain of our obligations that will be specified in
the applicable prospectus supplement.

                                       13
<PAGE>   131

     To establish such a trust we must deliver to the relevant Trustee an
opinion of counsel to the effect that the holders of those Debt Securities:

        - will not recognize income, gain or loss for U.S. federal income tax
          purposes as a result of the termination or covenant termination; and

        - will be subject to U.S. federal income tax on the same amounts, in the
          same manner and at the same times as would have been the case if the
          termination or covenant termination had not occurred.

     If we effect covenant termination with respect to any Debt Securities, the
amount of deposit with the relevant Trustee must be sufficient to pay amounts
due on the Debt Securities at the time of their stated maturity. However, those
Debt Securities may become due and payable prior to their stated maturity if
there is an Event of Default with respect to a covenant from which we have not
been released. In that event, the amount on deposit may not be sufficient to pay
all amounts due on the Debt Securities at the time of the acceleration.

     The applicable prospectus supplement may further describe the provisions,
if any, permitting termination or covenant termination, including any
modifications to the provisions described above.

GOVERNING LAW

     The Indentures and the Debt Securities will be governed by, and construed
in accordance with, the laws of the State of New York.

REGARDING THE TRUSTEES

     The Trust Indenture Act contains limitations on the rights of a trustee,
should it become a creditor of ours, to obtain payment of claims in certain
cases or to realize on certain property received by it in respect of any such
claims, as security or otherwise. Each Trustee is permitted to engage in other
transactions with us from time to time, provided that if such Trustee acquires
any conflicting interest, it must eliminate such conflict upon the occurrence of
an Event of Default under the relevant Indenture, or else resign.

                          DESCRIPTION OF CAPITAL STOCK

GENERAL

     As of the date of this prospectus, we are authorized to issue up to
40,000,000 shares of stock, including up to 35,000,000 shares of common stock
and up to 5,000,000 shares of preferred stock. As of June 15, 1999, we had
16,176,699 shares of common stock and no shares of preferred stock outstanding.
As of that date, we also had approximately 3,168,697 shares of common stock
reserved for issuance upon exercise of options or in connection with other
awards outstanding under various employee or director incentive, compensation
and option plans. There are an additional 3,646,847 shares of common stock
reserved for issuance upon conversion of our 6.25% Convertible Subordinated
Notes due November 15, 2006.

     The following is a summary of the key terms and provisions of our equity
securities. You should refer to the applicable provisions of our articles of
incorporation, bylaws, the Texas Business Corporation Act and the documents we
have incorporated by reference for a complete statement of the terms and rights
of our capital stock.

COMMON STOCK

     Voting Rights. Each holder of common stock is entitled to one vote per
share. Subject to the rights, if any, of the holders of any series of preferred
stock pursuant to applicable law or the provision of the certificate of
designation creating that series, all voting rights are vested in the holders of
shares of

                                       14
<PAGE>   132

common stock. Holders of shares of common stock have noncumulative voting
rights, which means that the holders of more than 50% of the shares voting for
the election of directors can elect 100% of the directors, and the holders of
the remaining shares voting for the election of directors will not be able to
elect any directors.

     Dividends. Dividends may be paid to the holders of common stock when, as
and if declared by the board of directors out of funds legally available for
their payment, subject to the rights of holders of any preferred stock. Swift
has never declared a cash dividend and intends to continue its policy of using
retained earnings for expansion of its business.

     Rights upon Liquidation. In the event of our voluntary or involuntary
liquidation, dissolution or winding up, the holders of common stock will be
entitled to share equally, in proportion to the number of shares of common stock
held by them, in any of our assets available for distribution after the payment
in full of all debts and distributions and after the holders of all series of
outstanding preferred stock, if any, have received their liquidation preferences
in full.

     Non-Assessable. All outstanding shares of common stock are fully paid and
non-assessable. Any additional common stock we offer and issue under this
Prospectus will also be fully paid and non-assessable.

     No Preemptive Rights. Holders of common stock are not entitled to
preemptive purchase rights in future offerings of our common stock.

     Listing. Our outstanding shares of common stock are listed on the New York
Stock Exchange and the Pacific Stock Exchange under the symbol "SFY." Any
additional common stock we issue will also be listed on the NYSE and the PSE.

PREFERRED STOCK

     Our board of directors can, without approval of our shareholders, issue one
or more series of preferred stock and determine the number of shares of each
series and the rights, preferences and limitations of each series. The following
description of the terms of the preferred stock sets forth certain general terms
and provisions of our authorized preferred stock. If we offer preferred stock, a
description will be filed with the SEC and the specific designations and rights
will be described in a prospectus supplement, including the following terms:

        - the series, the number of shares offered and the liquidation value of
          the preferred stock;

        - the price at which the preferred stock will be issued;

        - the dividend rate, the dates on which the dividends will be payable
          and other terms relating to the payment of dividends on the preferred
          stock;

        - the liquidation preference of the preferred stock;

        - the voting rights of the preferred stock;

        - whether the preferred stock is redeemable or subject to a sinking
          fund, and the terms of any such redemption or sinking fund;

        - whether the preferred stock is convertible or exchangeable for any
          other securities, and the terms of any such conversion; and

        - any additional rights, preferences, qualifications, limitations and
          restrictions of the preferred stock.

     The description of the terms of the preferred stock to be set forth in an
applicable prospectus supplement will not be complete and will be subject to and
qualified in its entirety by reference to the certificate of designation
relating to the applicable series of preferred stock. The registration statement
of

                                       15
<PAGE>   133

which this prospectus forms a part will include the certificate of designation
as an exhibit or incorporate it by reference.

     Undesignated preferred stock may enable our board of directors to render
more difficult or to discourage an attempt to obtain control of us by means of a
tender offer, proxy contest, merger or otherwise, and to thereby protect the
continuity of our management. The issuance of shares of preferred stock may
adversely affect the rights of the holders of our common stock. For example, any
preferred stock issued may rank prior to our common stock as to dividend rights,
liquidation preference or both, may have full or limited voting rights and may
be convertible into shares of common stock. As a result, the issuance of shares
of preferred stock may discourage bids for our common stock or may otherwise
adversely affect the market price of our common stock or any existing preferred
stock.

     Any preferred stock will, when issued, be fully paid and non-assessable.

ANTI-TAKEOVER PROVISIONS

     Certain provisions in our articles of incorporation, bylaws and our
shareholders' rights plan may encourage persons considering unsolicited tender
offers or other unilateral takeover proposals to negotiate with our board of
directors rather than pursue non-negotiated takeover attempts.

     Our Classified Board of Directors. Our bylaws provide that our board of
directors is divided into three classes as nearly equal in number as possible.
The directors of each class are elected for three-year terms, and the terms of
the three classes are staggered so that directors from a single class are
elected at each annual meeting of stockholders. A staggered board makes it more
difficult for shareholders to change the majority of the directors and instead
promotes continuity of existing management.

     Our Ability to Issue Preferred Stock. As discussed above, our board of
directors can set the voting rights, redemption rights, conversion rights and
other rights relating to authorized but unissued shares of preferred stock and
could issue that stock in either private or public transactions. Preferred stock
could be issued for the purpose of preventing a merger, tender offer or other
takeover attempt which the board of directors opposes.

     Our Rights Plan. Our board of directors has adopted a stockholders' rights
plan. The rights attach to all common stock certificates representing
outstanding shares. One right is issued for each share of common stock
outstanding. Each right entitles the registered holder, under the circumstances
described below, to purchase from us one one-thousandth of a share of our Series
A Junior Participating Preferred Stock, a "Series A" share, at a price of
$150.00 per one one-thousandth of a Series A share, subject to adjustment. The
dividend and liquidation rights and the non-redemption feature of the Series A
shares are designed so that the value of one one-thousandth of a Series A share
purchasable upon exercise of each right will approximate the value of one share
of common stock. The following is a summary of the terms of the rights plan. You
should refer to the applicable provisions of the rights plan which we have
incorporated by reference as an exhibit to the registration statement of which
this prospectus is a part.

     The rights will separate from the common stock and right certificates will
be distributed to the holders of common stock as of the earlier of:

        - 10 business days following a public announcement that a person or
          group of affiliated persons has acquired beneficial ownership of 15%
          or more of our outstanding voting shares; or

        - 10 business days following the commencement or announcement of an
          intention to commence a tender offer or exchange offer which would
          result in a person or group beneficially owning 15% or more of our
          outstanding voting shares.

     The rights are not exercisable until rights certificates are distributed.
The rights will expire on July 31, 2007 unless that date is extended or the
rights are earlier redeemed or exchanged.

     If a person or group acquires 15% or more of our voting shares, each right
then outstanding, other than rights beneficially owned by such person or group,
becomes a right to buy that number of shares of
                                       16
<PAGE>   134

common stock or other securities or assets having a market value of two times
the exercise price of the right. The rights belonging to the acquiring person or
group become null and void.

     If Swift is acquired in a merger or other business combination, or 50% of
its consolidated assets or assets producing more than 50% of its earning power
or cash flow are sold, each holder of a right will have the right to receive
that number of shares of common stock of the acquiring company which at the time
of such transaction has a market value of two times the purchase price of the
right.

     At any time after a person or group acquires beneficial ownership of 15% or
more of our outstanding voting shares and before the earlier of the two events
described in the prior paragraph or acquisition by a person or group of
beneficial ownership of 50% or more of our outstanding voting shares, our board
of directors may, at its option, exchange the rights, other than those owned by
such person or group, in whole or in part, at an exchange ratio of one share of
common stock or a fractional share of Series A stock or other preferred stock
equivalent in value thereto, per right.

     The Series A shares issuable upon exercise of the rights will be
non-redeemable and rank junior to all other series of our preferred stock. Each
whole Series A share will be entitled to receive a quarterly preferential
dividend in an amount per share equal to the greater of $1.00 in cash, or in the
aggregate, 1,000 times the dividend declared on the common stock, subject to
adjustment. In the event of liquidation, the holders of Series A share may
receive a preferential liquidation payment equal to the greater of $1,000 per
share, or in the aggregate, 1,000 times the payment made on the shares of common
stock. In the event of any merger, consolidation or other transaction in which
the shares of common stock are exchanged for or changed into other stock or
securities, cash or other property, each whole Series A share will be entitled
to receive 1,000 times the amount received per share of common stock. Each whole
Series A share will be entitled to 1,000 votes on all matters submitted to a
vote of our stockholders and Series A shares will generally vote together as one
class with the common stock and any other capital stock on all matters submitted
to a vote of our stockholders.

     Prior to the earlier of the date it is determined that right certificates
are to be distributed or the expiration date of the rights, our board of
directors may redeem all, but not less than all, of the then outstanding rights
at a price of $0.01 per right. Our board of directors in its sole discretion may
establish the effective date and other terms and conditions of the redemption.
Upon redemption, the ability to exercise the rights will terminate and the
holders of rights will only be entitled to receive the redemption price.

     As long as the rights are redeemable, we may amend the rights agreement in
any manner except to change the redemption price. After the rights are no longer
redeemable, we may, except with respect to the redemption price, amend the
rights agreement in any manner that does not adversely affect the interests of
holders of the rights.

     Business Combinations Under Texas Law. Swift is a Texas corporation subject
to Part Thirteen of the Texas Business Corporation Act known as the "Business
Combination Law." In general, the Business Combination Law prevents an
affiliated shareholder, or its affiliates or associates, from entering into a
business combination with an issuing public corporation during the three-year
period immediately following the date on which the affiliated shareholder became
an affiliated shareholder, unless:

        - before the date such person became an affiliated shareholder, the
          board of directors of the issuing public corporation approves the
          business combination or the acquisition of shares that caused the
          affiliated shareholder to become an affiliated shareholder; or

        - not less than six months after the date such person became an
          affiliated shareholder, the business combination is approved by the
          affirmative vote of holders of at least two-thirds of the issuing
          public corporation's outstanding voting shares not beneficially owned
          by the affiliated shareholder, or its affiliates or associates.

                                       17
<PAGE>   135

     An affiliated shareholder is a person that is or was within the preceding
three-year period the beneficial owner of 20% or more of a corporation's
outstanding voting shares. An issuing public corporation includes most publicly
held Texas corporations, including Swift. The term business combination
includes:

        - mergers, share exchanges or conversions involving the affiliated
          shareholder;

        - dispositions of assets involving the affiliated shareholder having an
          aggregate value of 10% or more of the market value of the assets or of
          the outstanding common stock or representing 10% or more of the
          earning power or net income of the corporation;

        - issuances or transfers of securities by the corporation to the
          affiliated shareholder other than on a pro rata basis;

        - plans or agreements relating to a liquidation or dissolution of the
          corporation involving an affiliated shareholder;

        - reclassifications, recapitalizations, distributions or other
          transactions that would have the effect of increasing the affiliated
          shareholder's percentage ownership of the corporation; and

        - the receipt of tax, guarantee, loan or other financial benefits by an
          affiliated shareholder other than proportionately as a shareholder of
          the corporation.

                        DESCRIPTION OF DEPOSITARY SHARES

     We may offer preferred stock represented by depositary shares and issue
depositary receipts evidencing the depositary shares. Each depositary share will
represent a fraction of a share of preferred stock. Shares of preferred stock of
each class or series represented by depositary shares will be deposited under a
separate deposit agreement among us, a bank or trust company acting as the
"Depositary" and the holders of the depositary receipts. Subject to the terms of
the deposit agreement, each owner of a depositary receipt will be entitled, in
proportion to the fraction of a share of preferred stock represented by the
depositary shares evidenced by the depositary receipt, to all the rights and
preferences of the preferred stock represented by such depositary shares. Those
rights include any dividend, voting, conversion, redemption and liquidation
rights. Immediately following the issuance and delivery of the preferred stock
to the Depositary, we will cause the Depositary to issue the depositary receipts
on our behalf.

     If depositary shares are offered, the applicable prospectus supplement will
describe the terms of such depositary shares, the deposit agreement and, if
applicable, the depositary receipts, including the following, where applicable:

        - the payment of dividends or other cash distributions to the holders of
          depositary receipts when such dividends or other cash distributions
          are made with respect to the preferred stock;

        - the voting by a holder of depositary shares of the preferred stock
          underlying such depositary shares at any meeting called for such
          purpose;

        - if applicable, the redemption of depositary shares upon a redemption
          by us of shares of preferred stock held by the Depositary;

        - if applicable, the exchange of depositary shares upon an exchange by
          us of shares of preferred stock held by the Depositary for debt
          securities or common stock;

        - if applicable, the conversion of the shares of preferred stock
          underlying the depositary shares into shares of our common stock,
          other shares of our preferred stock or our debt securities;

        - the terms upon which the deposit agreement may be amended and
          terminated;

        - a summary of the fees to be paid by us to the Depositary;

        - the terms upon which a Depositary may resign or be removed by us; and

        - any other terms of the depositary shares, the deposit agreement and
          the depositary receipts.
                                       18
<PAGE>   136

     If a holder of depositary receipts surrenders the depositary receipts at
the corporate trust office of the Depositary, unless the related depositary
shares have previously been called for redemption, converted or exchanged into
other securities of Swift, the holder will be entitled to receive at this office
the number of shares of preferred stock and any money or other property
represented by such depositary shares. Holders of depositary receipts will be
entitled to receive whole and, to the extent provided by the applicable
prospectus supplement, fractional shares of the preferred stock on the basis of
the proportion of preferred stock represented by each depositary share as
specified in the applicable prospectus supplement. Holders of shares of
preferred stock received in exchange for depositary shares will no longer be
entitled to receive depositary shares in exchange for shares of preferred stock.
If the holder delivers depositary receipts evidencing a number of depositary
shares that is more than the number of depositary shares representing the number
of shares of preferred stock to be withdrawn, the Depositary will issue the
holder a new depositary receipt evidencing such excess number of depositary
shares at the same time.

     Prospective purchasers of depositary shares should be aware that special
tax, accounting and other considerations may be applicable to instruments such
as depositary shares.

                            DESCRIPTION OF WARRANTS

     We may issue warrants for the purchase of preferred or common stock, either
independently or together with other securities. Each series of warrants will be
issued under a warrant agreement to be entered into between Swift and a bank or
trust company. You should refer to the warrant agreement relating to the
specific warrants being offered for the complete terms of such warrant agreement
and the warrants.

     Each warrant will entitle the holder to purchase the number of shares of
preferred or common stock at the exercise price set forth in, or calculable as
set forth in any applicable prospectus supplement. The exercise price may be
subject to adjustment upon the occurrence of certain events, as set forth in any
applicable prospectus supplement. After the close of business on the expiration
date of the warrant, unexercised warrants will become void. The place or places
where, and the manner in which, warrants may be exercised shall be specified in
any applicable prospectus supplement.

                              PLAN OF DISTRIBUTION

     We may sell the securities offered by this prospectus and applicable
prospectus supplements:

        - through underwriters or dealers;

        - through agents;

        - directly to purchasers; or

        - through a combination of any such methods of sale.

     Any such underwriter, dealer or agent may be deemed to be an underwriter
within the meaning of the Securities Act of 1933.

     The applicable prospectus supplement relating to the securities will set
forth:

        - their offering terms, including the name or names of any underwriters,
          dealers or agents;

        - the purchase price of the securities and the proceeds to us from such
          sale;

        - any underwriting discounts, commissions and other items constituting
          compensation to underwriters, dealers or agents;

        - any initial public offering price;

        - any discounts or concessions allowed or reallowed or paid by
          underwriters or dealers to other dealers;
                                       19
<PAGE>   137

        - in the case of debt securities, the interest rate, maturity and
          redemption provisions; and

        - any securities exchanges on which the securities may be listed.

     If underwriters or dealers are used in the sale, the securities will be
acquired by the underwriters or dealers for their own account and may be resold
from time to time in one or more transactions in accordance with the rules of
the New York Stock Exchange and the Pacific Stock Exchange:

        - at a fixed price or prices which may be changed;

        - at market prices prevailing at the time of sale;

        - at prices related to such prevailing market prices; or

        - at negotiated prices.

     The securities may be offered to the public either through underwriting
syndicates represented by one or more managing underwriters or directly by one
or more of such firms. Unless otherwise set forth in an applicable prospectus
supplement, the obligations of underwriters or dealers to purchase the
securities will be subject to certain conditions precedent and the underwriters
or dealers will be obligated to purchase all the securities if any are
purchased. Any public offering price and any discounts or concessions allowed or
reallowed or paid by underwriters or dealers to other dealers may be changed
from time to time.

     Securities may be sold directly by us or through agents designated by us
from time to time. Any agent involved in the offer or sale of the securities in
respect of which this prospectus and a prospectus supplement is delivered will
be named, and any commissions payable by us to such agent will be set forth, in
the prospectus supplement. Unless otherwise indicated in the prospectus
supplement, any such agent will be acting on a best efforts basis for the period
of its appointment.

     If so indicated in the prospectus supplement, we will authorize
underwriters, dealers or agents to solicit offers from certain specified
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. Such
contracts will be subject to any conditions set forth in the prospectus
supplement and the prospectus supplement will set forth the commission payable
for solicitation of such contracts. The underwriters and other persons
soliciting such contracts will have no responsibility for the validity or
performance of any such contracts.

     Underwriters, dealers and agents may be entitled under agreements entered
into with us to be indemnified by us against certain civil liabilities,
including liabilities under the Securities Act of 1933, or to contribution by
Swift to payments which they may be required to make. The terms and conditions
of such indemnification will be described in an applicable prospectus
supplement. Underwriters, dealers and agents may be customers of, engage in
transactions with, or perform services for, us in the ordinary course of
business.

     Each class or series of securities will be a new issue of securities with
no established trading market, other than the common stock, which is listed on
the New York Stock Exchange and the Pacific Stock Exchange. We may elect to list
any other class or series of securities on any exchange, other than the common
stock, but we are not obligated to do so. Any underwriters to whom securities
are sold by us for public offering and sale may make a market in such
securities, but such underwriters will not be obligated to do so and may
discontinue any market making at any time without notice. No assurance can be
given as to the liquidity of the trading market for any securities.

     Certain persons participating in any offering of securities may engage in
transactions that stabilize, maintain or otherwise affect the price of the
securities offered. In connection with any such offering, the underwriters or
agents, as the case may be, may purchase and sell 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. Stabilizing transactions consist of certain bids or purchases for the
purpose of preventing or retarding a decline in the market price of the
securities; and
                                       20
<PAGE>   138

syndicate short positions involve the sale by the underwriters or agents, as the
case may be, of a greater number of securities than they are required to
purchase from us, as the case may be, in the offering. The underwriters may also
impose a penalty bid, whereby selling concessions allowed to syndicate members
or other broker-dealers for the securities sold for their account may be
reclaimed by the syndicate if such securities are repurchased by the syndicate
in stabilizing or covering transactions. These activities may stabilize,
maintain or otherwise affect the market price of the securities, which may be
higher than the price that might otherwise prevail in the open market, and if
commenced, may be discontinued at any time. These transactions may be effected
on the New York Stock Exchange, the Pacific Stock Exchange, in the
over-the-counter market or otherwise. These activities will be described in more
detail in the sections entitled "Plan of Distribution" or "Underwriting" in the
applicable prospectus supplement.

                                 LEGAL OPINIONS

     Jenkens & Gilchrist, A Professional Corporation, Houston, Texas, will issue
an opinion for Swift regarding the legality of the securities offered by this
prospectus and applicable prospectus supplement. If the securities are being
distributed in an underwritten offering, certain legal matters will be passed
upon for the underwriters by counsel identified in the applicable prospectus
supplement.
