                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information appearing elsewhere or incorporated by reference in this Prospectus.
All information giving effect to this Offering assumes that the Underwriters'
over-allotment option is not exercised unless otherwise noted.
 
                                  THE COMPANY
 
     Snyder Oil Corporation (the "Company") is engaged in the development and
acquisition of oil and gas properties primarily in the Rocky Mountain region of
the United States. The Company also gathers, transports, processes and markets
natural gas generally in proximity to its principal producing properties. Over
the five year period from 1988 to 1993, revenues increased from $14.7 million to
$229.9 million, net income increased from $5.1 million to $25.7 million and net
cash provided by operations increased from $8.1 million to $68.3 million. At
December 31, 1993, the Company's net proved reserves totaled 103.6 MMBOE, having
a pretax present value at constant prices of $390.4 million. Approximately 69%
of its proved reserves are natural gas.
 
     Approximately 90% of the present value of the Company's proved reserves is
concentrated in five major producing areas located in Colorado, Wyoming and
Texas. In total, the Company's properties are located in 15 states and the Gulf
of Mexico and include 5,122 gross (2,187 net) producing wells and nine gas
transportation and processing facilities. The Company operates more than 2,100
wells which account for over 90% of its developed reserves. In addition to its
domestic operations, the Company is also participating in several international
exploration and development projects through its wholly owned subsidiary, SOCO
International, Inc., and through its 36% owned affiliate, Command Petroleum
Holdings NL. At December 31, 1993, the Company held undeveloped acreage totaling
539,000 gross acres (326,000 net) domestically and 4.3 million gross acres (3.3
million net) internationally.
 
   
     The Company has pursued a balanced strategy of development drilling and
acquisitions, focusing on operating efficiency and enhanced profitability
through the concentration of assets in selected geographic areas or "hubs."
Currently, the primary emphasis of the Company's growth strategy is development
drilling in the Rockies, mainly the Wattenberg Field in the Denver-Julesburg
Basin ("DJ Basin") of Colorado where the Company drilled 323 wells in 1993. In
implementing this strategy in the Wattenberg Field over the past three years,
the Company has achieved the following: (i) drilled approximately 667 wells, 660
of which are currently producing; (ii) increased production more than five
times, from an average of 2.6 MBOE per day in 1991 to an average of 13.3 MBOE
per day in 1993; (iii) increased proved reserves nearly 50% from 37.9 MMBOE at
yearend 1991 to 55.2 MMBOE at yearend 1993; and (iv) generally reduced drilling
and completion costs by over 30% through a combination of aggressive cost
cutting, economies of scale and technological improvements. Through a major
joint venture with Union Pacific Resources Company, as well as acquisitions and
leasing, the Company has accumulated a substantial inventory of potential
drilling locations, including 1,102 locations that were classified as proved
undeveloped at December 31, 1993.
    
 
     In 1993, the Company embarked on a program to apply the experience gained
in the Wattenberg Field to two other large scale gas developments in the
Rockies. In the Washakie Basin of southern Wyoming (the "East Washakie
Project"), the Company currently operates 128 wells and holds a significant
inventory of potential drilling locations, including 98 locations that were
classified as proved undeveloped at December 31, 1993. The Company has also
initiated the development of a third hub in the Rockies through three purchase
transactions, as well as farmouts and leasing. As a result, the Company
currently holds a significant inventory of potential drilling locations in the
Piceance and Uinta Basins of Colorado and Utah (collectively, the "Western Slope
Project"), including 101 locations that were classified as proved undeveloped at
December 31, 1993.
 
     During 1994, the Company intends to continue development in the DJ Basin
and to increase activity in the East Washakie and Western Slope Projects. The
Company expects to spend $175 to $200 million for development drilling and
expansion of gas facilities in 1994, including the drilling of over 650 wells,
500 of which are planned for the Wattenberg Field and up to 90 for the East
Washakie and Western Slope Projects. As part of this program, the Company will
emphasize the improvement of well economics through the use of technological
improvements and cost saving drilling techniques, as well as the capture of
downstream margins via the Company's gas facilities. In addition to development
drilling in the Rockies, the Company intends to pursue acquisitions to
strengthen its existing asset base and secure a foothold in new geographic areas
and to continue progress in bringing its international projects to fruition.

                             obtain the requisite consents under such Senior
                             Indebtedness to permit the repurchase of the Notes
                             could result in an Event of Default (as defined)
                             under the indenture (the "Indenture") with respect
                             to the Notes.
    
 
   
Ranking....................  Subordinated to all existing and future Senior
                             Indebtedness of the Company. The Indenture will not
                             restrict the incurrence of Senior Indebtedness or
                             other indebtedness by the Company or any subsidiary
                             of the Company. The Notes are effectively
                             subordinated to all existing and future liabilities
                             of the Company's subsidiaries to the extent of the
                             assets of such subsidiaries. Immediately following
                             the sale of the Notes offered hereby and
                             application of the net proceeds therefrom, the
                             Company estimates that the sum of its Senior
                             Indebtedness and the indebtedness of its
                             subsidiaries will total approximately $50 million.
    
 
   
Sinking Fund...............  None.
    
 
Use of Proceeds............  To repay a portion of the borrowings outstanding
                             under the Company's bank credit facility. The
                             Company intends to use the resulting borrowing
                             capacity under its credit facility to fund
                             development drilling, expansion of its gas
                             facilities and potential acquisitions.

    (a) For the purpose of calculating the ratio of earnings to fixed charges,
       "earnings" consist of income before taxes, accounting change,
       extraordinary item and "fixed charges." "Fixed charges" include interest
       on indebtedness and the portion of rental expense, excluding rent on
       capitalized leases, estimated to be representative of the interest factor
       in rental expense.
   
    (b) The ratio of earnings to fixed charges and the ratio of EBITDA to fixed
       charges, pro forma for the issuance of $100 million principal amount of
       Notes offered hereby, would be 4.6x and 10.4x, respectively.
    
    (c) EBITDA is income before (i) accounting change and extraordinary item,
       (ii) taxes, (iii) depletion, depreciation and amortization and (iv)
       interest.
    (d) Includes $56.1 million incurred in connection with properties acquired
       in December 1992, $49.8 million of which was paid in February 1993.
    (e) Due to revised payment timing, five payments were made at the $.05
       quarterly rate in 1992.
    (f) Gas production is converted to oil equivalents at the rate of 6 Mcf per
       barrel except for Thomasville production which, through 1992, was
       converted based on its price equivalency to the Company's other gas.
       Average gas prices exclude Thomasville production.
    (g) Includes production and severance taxes.
    (h) Adjusted to give effect to the application of the estimated net proceeds
       of this Offering. See "Use of Proceeds."

                              SUMMARY RESERVE DATA
 
     The following table sets forth information on estimated proved oil and gas
reserves, future net cash flow before taxes from such reserves and the pretax
present value of such cash flow, using unescalated prices and costs and a 10%
per annum discount rate ("Pretax PW10% Value"). The prices used in the yearend
reserve estimates averaged $11.49 per barrel of oil and $2.11 per Mcf of gas
over the life of the reserves.
 


                                                                  DECEMBER 31, 1993

    Estimated proved reserves:
      Crude oil and liquids (Bbl).....................     18,032         13,898        31,930
      Natural gas (Mcf)...............................    268,349        161,740       430,089
      BOE(a)..........................................     62,757         40,855       103,612
    Future net cash flow from estimated production....  $ 474,480      $ 213,792      $688,272
    Pretax PW10% Value(b).............................  $ 297,638      $  92,771      $390,409
    -------------

 
     (a) Natural gas reserves are converted to oil equivalents at the rate of 6
        Mcf per Bbl.
     (b) The after-tax present value of proved reserves totalled $340.5 million
        at December 31, 1993.
 
     The revenues generated by the Company are highly dependent upon the prices
of crude oil and gas. The volatility of energy prices makes it particularly
difficult to estimate future prices of oil and gas. Price fluctuations change
reserve values by altering the quantities of reserves that are recoverable on an
economic basis as well as the future net revenues attributable to the reserves.
Any significant decline in prices of oil or gas could have a material adverse
effect on the Company's financial condition and results of operations.
 
   
     Unless otherwise indicated in this Prospectus, as used herein, the term
"Btu" means British Thermal Unit, the term "MMBtu" means million Btus, the term
"Mcf " means thousand cubic feet, the term "MMcf " means million cubic feet, the
term "Bcf " means billion cubic feet, the term "Bbl" means barrel, the term
"MBbl" means thousand barrels, the term "MMBbl" means million barrels, the term
"BOE" means barrel of oil equivalent, the term "MBOE" means thousand barrels of
oil equivalent and the term "MMBOE" means million barrels of oil equivalent. Gas
is converted into a barrel of oil equivalent based on six Mcf of gas to one Bbl
of oil, except as otherwise described herein. A "gross acre" or "gross well" is
an acre or well in which an interest is owned. "Net acres" or "net wells" are
obtained by multiplying gross acres or wells by the Company's working interest
in the applicable properties.

                                USE OF PROCEEDS
 
   
     The net proceeds from the sale of the Notes are estimated to be
approximately $     million ($     million if the Underwriters' over-allotment
option is exercised in full). The Company intends to use the net proceeds to
repay a portion of the borrowings outstanding under its bank credit facility.
The Company intends to use the resulting borrowing capacity under its credit
facility to fund development drilling, expansion of its gas facilities and
potential acquisitions. The Company estimates that it will expend $175 to $200
million for development drilling and expansion of gas facilities during 1994,
assuming no material changes in oil and gas prices. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
    
 
   
     On April 18, 1994 approximately $135.2 million was outstanding under the
Company's revolving bank credit facility. The rate of interest on this debt
fluctuates based on various rates, as selected by the Company. The weighted
average interest rate on bank borrowings at such date was 4.99%. The facility
expires on December 31, 1997. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
RESULTS OF OPERATIONS(A)
 
     Comparison of 1993 results to 1992. Total revenues rose 91% in 1993 to
$229.9 million. Net income before taxes and extraordinary items more than
doubled to reach $34.9 million in 1993. The increase was led by a rapid rise in
production and assisted by an increase in gas processing and transportation
margins. Before the effect of a favorable $3.8 million income tax accounting
change in 1992 and a $1.9 million 1993 extraordinary charge on early retirement
of debt, earnings per common share were $.80 in 1993 compared to $.53 in 1992, a
51% increase.
 
     The gross margin from production operations for 1993 increased 62% to $79.7
million, which was primarily related to a 65% growth in oil and gas production.
The price received per equivalent barrel decreased by 3% to $13.41. Total
operating expenses including production taxes increased 60% during 1993 although
operating cost per BOE decreased to $4.83 from $4.99 in 1992. Expense reductions
gained from wells added in the DJ Basin, where operating costs averaged $2.76
per BOE, were partially offset by the late 1992 acquisition of Wyoming wells
from a major oil company where 1993 operating costs averaged $7.45 per BOE.
 
     For the year ended December 31, 1993, average daily production was 25,472
BOE, a 65% increase from 1992. Average daily production in the fourth quarter of
1993 climbed to 10,314 Bbls and 105.6 MMcf (27,917 BOE). The production
increases resulted primarily from acquisitions and continuing development
drilling in the DJ Basin. Domestically, $51.0 million in properties were
acquired in 1993, primarily in and around existing hubs in Colorado and Wyoming.
The acquisitions included a significant number of development locations and
should continue to add to production in 1994. In 1993, 311 wells were placed on
production in the DJ Basin, with 51 wells in various stages of drilling and
completion at yearend. Because the majority of the wells were added in the
latter part of the year, production will not be fully impacted until 1994.
Additionally, significant downtime was experienced in the fourth quarter at the
major processing plant in the DJ Basin, which increased line pressures and
hampered production. To a lesser extent, this situation continued into early
1994.
 
   
     The gross margin from gas processing, transportation and marketing
activities for 1993 increased 23% to $10.0 million from $8.1 million in 1992.
The increase was primarily attributable to a $3.0 million (49%) rise in
transportation and processing margins as a result of additional DJ Basin
production and the recent expansion of the related facilities. Gas marketing
margins for 1993 decreased by $1.1 million due to reduced margins on the
Company's Oklahoma cogeneration supply contract, which declined as a result of
an imposed limitation of the contract sales price and rising gas purchase costs.
In 1993 the net contract margin was a loss of $267,000, which was $1.8 million
less than 1992. At present gas price levels, the Company foresees continued
negative or breakeven margins for the cogeneration contract through July 1994.
At that time, a change in the pricing formula should result in improved margins.
The cogeneration margin reduction was partially offset by a $667,000 (126%) rise
in other gas marketing margins in 1993 resulting from increased third party
marketing.
    
 
     Other income was $10.4 million during 1993, compared to $4.2 million in
1992. The $6.2 million increase resulted from a $3.5 million gas contract
settlement received in April 1993, collection of a $1.7 million litigation
judgment and greater gains on the sales of securities.
 
     General and administrative expenses, net of reimbursements, for 1993
represented 3% of revenues compared to 5.6% in 1992 as expenses were held
essentially flat while revenues grew 91%. Interest and other expenses increased
28% primarily as a result of a rise in outstanding debt balances. Senior debt
was substantially reduced in April 1993 with proceeds from a preferred offering,
but increased through yearend as

(a) Prior to 1993, production from the Thomasville Field, which was sold at
    prices that were significantly above market, was converted to equivalent
    barrels based on its price relative to the Company's other gas production.
    Beginning in 1993, Thomasville production was converted to oil equivalents
    at the rate of 6 Mcf per barrel. In order to provide comparability between
    periods, equivalent barrel information, other than depletion rates, for 1992
    and 1991 has been restated in this section to reflect Thomasville production
    at the conversion rate of 6 Mcf per barrel. All equivalent barrel
    information presented elsewhere in this Prospectus reflects the historical
    method of conversion of Thomasville production used by the Company in the
    applicable year.
 
                                       10

a result of development expenditures, acquisitions, the investment in Command
Petroleum Holdings NL and the retirement of $25.0 million in subordinated debt.
 
     Depletion, depreciation and amortization during 1993 increased 60% from the
prior year. The increase was the direct result of the 65% rise in equivalent
production between years. The producing depletion rate per BOE for 1993 was
reduced to $4.75 from $4.79 in 1992. The rate was reduced by an ongoing drilling
cost reduction program, partially offset by an increase from the discontinuation
of converting Thomasville production to equivalent quantities based on relative
gas prices.
 
     The Company adopted FASB Statement No. 109, "Accounting for Income Taxes,"
effective January 1, 1992. Net income for 1992 was increased by $3.8 million for
the cumulative effect of the change in method of accounting for income taxes. In
1992 the income tax provision was reduced from the statutory rate of 34% by $5.5
million due to the elimination of deferred taxes as a result of tax basis in
excess of financial basis. In 1993 the income tax provision was reduced from the
newly enacted rate of 35% to an effective rate of approximately 20% as a result
of full realization of the excess basis benefit. The Company anticipates
deferred taxes will be provided in 1994 and beyond based on the full statutory
rate and accordingly will increase substantially.
 
     Comparison of 1992 results to 1991. Revenues rose 30% in 1992 to $120.2
million, compared to $92.5 million in 1991. Net income for 1992 was $20.6
million, a 134% increase from the $8.8 million in 1991. The increases resulted
from greater oil and gas production volumes, lower interest expense, reduced
general and administrative expenses and a $3.8 million reversal of the
cumulative effect of prior year deferred taxes with the adoption of a change in
the method of accounting for income taxes.
 
     Average daily production for 1992 rose 24% to 15,408 BOE due mostly to
development drilling in the DJ Basin of Colorado as 189 wells were placed on
production there. As a result, the gross margin from production increased 22% to
$49.3 million in 1992. The price per BOE decreased 4% during 1992.
 
     The gross margin from gas processing, transportation and marketing
activities for 1992 increased 12% to $8.1 million from $7.3 million in 1991. The
growth was primarily the result of increased marketing of third party gas in New
Mexico, Colorado and Wyoming. Gas processing and transportation margins
increased moderately as volumes were increased late in the year by expansions of
pipeline and plant facilities to take advantage of increasing DJ Basin
production. Other income for 1992 decreased 26% to $4.2 million from a reduction
in gains on sales of securities and lower interest on notes receivable.
 
     Direct operating expenses including production taxes increased only 13%
during 1992 as the operating cost per BOE decreased to $4.99 from $5.47 in 1991,
due to increased DJ Basin production where operating costs have been
significantly lower than average. General and administrative expenses, net of
reimbursements, for 1992 represented less than 6% of revenues compared to 8% in
1991, as revenues rose 30%. Interest and other expenses dropped 39% in 1992 due
to lower average outstanding senior debt after the application of proceeds from
a preferred stock offering in late 1991.
 
DEVELOPMENT, ACQUISITION AND EXPLORATION
 
     During 1993 the Company expended $93.1 million for oil and gas property
development and exploration, $51.0 million for acquisitions and $22.6 million
for gas facility expansion and other assets, for a total of $166.7 million in
property and equipment expenditures. Additionally, the Company made an $18.2
million investment in an Australian based exploration and production company.
 
     The Company has concentrated a significant portion of its development
activities in the DJ Basin. Capital expenditures for DJ Basin development
totalled $75.4 million during 1993. A total of 311 newly drilled wells were
placed on production there in 1993 and 51 were in progress at yearend.
Additionally, 42 recompletions were performed in 1993, with seven in process at
yearend. In December 1993, 16 drilling rigs were in operation in the DJ Basin.
The Company anticipates putting 500 or more wells per year on production in the
DJ Basin for the next few years. With additional leasing activity and through
drilling cost reductions that add proved undeveloped locations as they become
economic, the Company has increased the inventory of available drillsites. In
December 1993, the Company entered into a letter of intent with Union Pacific
Resources Company ("UPRC") whereby the Company will gain the right to drill
wells on UPRC's previously uncommitted acreage throughout the Wattenberg area.
This transaction significantly increased the Company's undeveloped Wattenberg
inventory. UPRC will retain a royalty and the right to participate as a 50%

shares of Company stock. Of the warrants, one million expire three years from
the date of grant, and are exercisable at $25 per share, while the other one
million expire in four years and are exercisable at $27 per share. On February
8, 1995, the exercise prices may be reduced to 120% of the average closing price
of the Company stock for the preceding 20 consecutive trading days, but not
below $21.60 per share. The expiration date of the warrants will be extended one
year if the average closing price over such 20 day trading period is less than
$16.50 per share.
 
     The Company expended $14.8 million for other development and recompletion
projects and $2.9 million for exploration during 1993. In Nebraska, 29 wells
were added to production in 1993 as an extension of a drilling program initiated
in 1992. An additional 20 wells are planned in Nebraska for 1994. In southern
Wyoming, 11 wells in the East Washakie Basin development program were
successfully drilled and completed during the last half of 1993 with three in
process at yearend. In this program, significant cost-cutting measures were
applied based on the experience gained in the DJ Basin. In central Wyoming on
the properties acquired from a major oil company in late 1992, efforts have been
focused on increasing operating efficiency with limited development drilling and
workover activity. In 1993, three successful wells were drilled in the fourth
quarter and selected development and recompletion activity is scheduled for
1994. In the Piceance Basin of western Colorado, a three well test program was
started in December of 1993 on acreage acquired there during the year, with one
well undergoing completion, the second in progress and a third scheduled for
early 1994. Current plans include a minimum of 25 wells in the basin during
1994. In South Texas, a combined operated and non-operated program was
initiated, with nine wells completed in 1993 and one well abandoned. A total of
25 additional horizontal locations have been identified and drilling should
continue with as many as 15 wells planned in 1994. In its domestic exploration
efforts, the Company initiated a seismic program in Louisiana and began drilling
early in the fourth quarter. Advanced seismic techniques are being used to
identify further prospects in Louisiana and expectations are to drill up to 20
wells in 1994.
 
     A total of $51.0 million in domestic acquisitions were completed in 1993.
In May 1993, the Company purchased an interest in 121 producing wells and over
70 drilling locations in the DJ Basin area for $3.3 million. In July, an
incremental 25% interest in the Company's Barrel Springs and Duck Lake Fields in
Wyoming was purchased for $6.1 million. The properties are 90% gas and include
44 producing wells and 46 undeveloped locations. In August, the Company acquired
interests in 225 producing wells and 272 proved undeveloped locations in the DJ
Basin for $19.7 million. The proved reserves are 70% gas with more than two-
thirds requiring future development to produce. Late in the year, two
acquisitions were completed in the Piceance and Uinta Basins of Western Colorado
for a total of $12.5 million. The majority of the value was in undeveloped
locations as only 128 wells were currently producing. Numerous other producing
and undeveloped acquisitions totalling $9.4 million were completed, mostly in or
close to the Company's principal operating areas.
 
     The Company's gas gathering and processing facilities have been undergoing
significant transformation since late 1992. In 1993, the Company expended $20.1
million to develop further its gas related assets. The Company spent $9.4
million toward the second phase of its DJ Basin gathering expansion to construct
a high pressure line to deliver gas directly to the major gas processing plant
in the area and expand its gathering network for the increased drilling
activity. An additional $2.6 million was expended to expand the Roggen Plant for
the production increases. A total of $5.6 million in additional transportation
and gathering facilities were constructed in the DJ Basin including a nine mile
16" interconnect line completed in October to relieve high line pressures, a 20"
western gathering extension and numerous other extensions and connections. A
gathering system that delivers third party gas to the Roggen Plant was purchased
for $703,000. The Company expended $1.4 million to complete construction of a
system to gather gas from its Nebraska drilling project. These projects are
intended to take advantage of the significant increase in drilling activity in
these areas.
 
     In May 1993, the Company acquired 42.8% (currently 35.7%) of the
outstanding shares of Command Petroleum Holdings NL ("Command"), a Sydney based
Australian exploration and production company listed on the Australian Stock
Exchange, for $18.2 million. Command holds interests in more than 20 exploration
permits and licenses and a 28.7% interest in a Netherlands exploration and
production company whose assets are located primarily in the North Sea. Permtex,
the Company's Russian joint venture, received central government approval in
August and the Company executed a finance and insurance protocol with the
 
                                       12
   14
 
Overseas Private Investment Corporation ("OPIC"), a United States government
agency. Current plans call for 25 of the existing 45 shut-in wells to be placed
on production in 1994, and that 400 development wells will be drilled over the
next ten years. Extensive seismic work began in the fourth quarter of 1993 for
400 kilometers of data in Tunisia and 500 kilometers in Mongolia.
 
     The Company from time to time acquires securities of publicly traded and
private oil and gas companies. In addition to its investment in Command, the
Company owns, among other investments, more than 5% of the common stock of Lomak
Petroleum, Inc. and, as the result of purchases beginning in the third quarter
of 1993, American Exploration Company. The Company is currently evaluating a
range of possible alternatives with respect to its investment in American
Exploration Company, including the possibility of actions to enhance the value
of its common stock.
 
FINANCIAL CONDITION AND CAPITAL RESOURCES
 
     At December 31, 1993, the Company had total assets of $480 million and
working capital of $1.3 million. Total capitalization was $412 million, of which
28% was represented by senior debt and the remainder by stockholders' equity.
During 1993, the Company fully retired its $25 million of 13.5% subordinated
notes and the related cumulative participating interests. During 1993, cash
provided by operations was $68.3 million, an increase of 43% over 1992. As of
December 31, 1993, commitments for capital expenditures totalled $7.5 million,
primarily for DJ Basin drilling. The Company anticipates that it will expend
$175 to $200 million for development drilling and expansion of gas facilities in
1994. The level of these and other future expenditures is largely discretionary,
and the amount of funds devoted to any particular activity may increase or
decrease significantly, depending on available opportunities and market
conditions. The Company plans to finance its ongoing development, acquisition
and exploration expenditures using internally generated cash flow, proceeds from
property dispositions and existing credit facilities. In addition, joint
ventures or future public and private offerings of securities may be utilized.
 
     In 1992, an institutional investor agreed to contribute $7 million to a
partnership formed to monetize Section 29 tax credits to be realized from the
Company's properties, mainly in the DJ Basin. The initial $3 million was
contributed in October 1992, and at first payout in June 1993 the second
contribution of $1.5 million was received. An additional $1.5 million was
received in October 1993. This transaction should increase the Company's cash
flow and net income through 1994. A revenue increase of more than $.40 per Mcf
is realized on production generated from qualified Section 29 properties in this
partnership. The Company recognized $3.8 million of this revenue during 1993.
Discussions are in progress to expand the scope of this transaction so that the
benefits would be continued through at least 1996.
 
     In April 1993, the Company sold 4.1 million depositary shares (each
representing a one quarter interest in one share of $100 liquidation value
stock) of convertible preferred stock through an underwritten offering for
$103.5 million. A portion of the net proceeds of $99.3 million was used to
retire the entire outstanding balance under the revolving credit facility at
that time. The preferred stock pays a 6% dividend and is convertible into common
stock at $21.00 per share. At the Company's option, the preferred stock is
exchangeable into 6% convertible debentures on any dividend payment date on or
after March 31, 1994. The preferred stock is redeemable at the option of the
Company on or after March 31, 1996.
 
     Effective July 1, 1993, the Company renegotiated its bank credit facility
and increased it from $150 million to $300 million. The new facility is divided
into a $50 million short-term portion and a $250 million long-term portion that
expires on December 31, 1997. However, management's policy is to request renewal
of the facility annually. Credit availability is adjusted semiannually to
reflect changes in reserves and asset values. At December 31, 1993, the elected
borrowing base was $150 million. The majority of the borrowings currently bear
interest at LIBOR plus 1.25% with the remainder at prime. The Company also has
the option to select the CD rate plus 1.375%. Financial covenants limit debt,
require maintenance of minimum working capital and restrict certain payments,
including stock repurchases, dividends and contributions or advances to
unrestricted subsidiaries. Based on such limitations, $86.5 million would have
been available for the payment of dividends and other restricted payments as of
December 31, 1993. The Company does not currently plan to make, and is not
committed to make, any advances or contributions to unrestricted subsidiaries
that would materially affect its ability to pay dividends under this limitation.
 
                                       13
   15
 
     The Company maintains a program to divest marginal properties and assets
that do not fit its long range plans. For 1992 and 1993, proceeds from these
sales were $3.0 million and $5.5 million, respectively. Included in the 1993
proceeds were $4.0 million of cash receipts previously accrued for late 1992
sales. The Company intends to continue to evaluate and dispose of nonstrategic
assets.
 
     The Company believes that its capital resources are more than adequate to
meet the requirements of its business. However, future cash flows are subject to
a number of variables including the level of production and oil and gas prices,
and there can be no assurance that operations and other capital resources will
provide cash in sufficient amounts to satisfy debt service requirements and to
maintain planned levels of capital expenditures or that increased capital
expenditures will not be undertaken.
 
INFLATION AND CHANGES IN PRICES
 
     While certain of its costs are affected by the general level of inflation,
factors unique to the petroleum industry result in independent price
fluctuations. Over the past five years, significant fluctuations have occurred
in oil and gas prices. Although it is particularly difficult to estimate future
prices of oil and gas, price fluctuations have had, and will continue to have, a
material effect on the Company.
 
                            BUSINESS AND PROPERTIES
GENERAL
 
     Snyder Oil Corporation is engaged in the development and acquisition of oil
and gas properties primarily in the Rocky Mountain region of the United States.
The Company also gathers, transports, processes and markets natural gas
generally in proximity to its principal producing properties. Over the five year
period from 1988 to 1993, revenues increased from $14.7 million to $229.9
million, net income increased from $5.0 million to $25.7 million and net cash
provided by operations increased from $8.1 million to $68.3 million. At December
31, 1993, the Company's net proved reserves totaled 103.6 MMBOE, having a pretax
present value at constant prices of $390.4 million. Approximately 69% of its
proved reserves are natural gas.
 
     The Company is headquartered at 777 Main Street, Fort Worth, Texas 76102
(telephone 817-338-4043). The Company also maintains administrative offices in
Denver and New York and has eight field offices in Colorado, Wyoming, Texas, New
Mexico and Nebraska.
 
DEVELOPMENT
 
     GENERAL. Since 1990, development drilling has become the primary focus of
the Company's growth strategy. The Company believes that its existing properties
have extensive development drilling and enhancement potential, primarily in the
DJ Basin of Colorado, the Washakie Basin in southern Wyoming, the Piceance and
Uinta Basins in western Colorado and Utah and in the Giddings Field in southern
Texas. The Company designs its major drilling programs to reduce risk, create
synergies with its gas management operations and exploit the potential for
continuous cost improvement. In 1994, the Company expects to drill over 650
wells, including approximately 500 wells in the Wattenberg Field, where the size
of its operations enables it to continue to refine the application of new
drilling, completion and operating techniques, and to apply the experience
gained there to establish other large scale development projects in the Rockies.
 
     In its large scale development projects, the Company also attempts to
acquire and maintain a sizeable inventory of potential drilling locations, many
of which may not be economic at current cost and price levels, but which the
Company believes may ultimately prove attractive to develop if reservoir
assumptions are validated and well economics improve over the life of the
project through cost reductions or price increases. No assurances can be given
that such conditions will be satisfied and, accordingly, that such locations
will be drilled.
 
     Assuming no material changes in product prices and capital availability,
the Company estimates that it will expend from $150 to $200 million per year for
development drilling and gas facilities over the next three to five years. Such
expenditures totalled $64.8 million in 1992 and $112.8 million in 1993,
primarily in the Wattenberg Field.
 
                                       14
   16
 
                                    DJ BASIN
 
     WATTENBERG FIELD. The Wattenberg Field is the Company's largest base of
operations, representing over 55% of total proved reserves. Between 1991 and
1993, the Company drilled a total of 667 wells in Wattenberg, of which 323 were
drilled during 1993. At yearend, the Company had interests in more than 1,400
producing wells, of which the Company operated over 1,100. Through a major joint
venture with UPRC, complementary acquisitions and an extensive leasing program,
the Company has accumulated up to 6,000 potential drilling locations in the
Wattenberg Field. The Company expects that over half of these sites will
ultimately prove attractive to develop. The Company expects to drill
approximately 500 wells per year in the Wattenberg Field for at least the next
several years.
 
     At yearend 1993, the net proved reserves attributed to the Wattenberg
properties were 16.9 million barrels of oil and 229.9 Bcf of gas. The reserves
were attributable to 1,437 producing wells, 51 wells in progress, 1,102 proved
undeveloped locations and approximately 387 proved behind pipe zones. The
Company expects proved reserves to be assigned to other locations as drilling
progresses.
 
     The Company acquired its first properties in Wattenberg during 1986. In
1990, it substantially increased its acreage position by acquiring rights to the
Codell and Niobrara formations underlying 32,985 net acres from Amoco Production
Company ("Amoco") for $14.4 million. Several farm-ins from Amoco in 1992,
financed primarily through a transfer of Section 29 tax credits, resulted in
earning additional Codell/Niobrara rights as well as rights to the Sussex,
J-Sand and Dakota formations in a number of locations. During 1993, a series of
purchases added nearly 9 MMBOE at a net cost of under $3.50 per barrel as well
as several pipeline and processing facilities that complement existing
facilities. See "-- Acquisition Program."
 
     In early 1994, the Company finalized an agreement with UPRC under which the
Company has the right for up to six years to drill wells on locations of its
choosing on UPRC's previously uncommitted undeveloped acreage throughout the
Wattenberg area. This transaction substantially increased the Company's
Wattenberg undeveloped acreage inventory. Many of the locations have the
potential for improved economics through completion in one or more of the
Shannon, Sussex, J-Sand or Dakota formations, as well as the Codell and
Niobrara. During the venture's initial three-year term, the Company is required
to drill a minimum of 120, 120 and 60 wells per year. After the initial period,
the Company can, at its option, extend the venture annually for up to three
additional years by drilling at least 150 wells per year. There is no limit on
the maximum number of wells that can be drilled, and wells in excess of the
required minimum in any year will reduce the number of wells required in the
following year by up to 50%. If the Company drills less than the minimum number
of wells, it is required to pay UPRC $20,000 per well for the shortfall. On each
well that is drilled on UPRC's mineral acreage under the venture, UPRC retains a
15% mineral owner royalty and has the option either to receive an additional 10%
royalty interest after pay-out or to participate in the well as a 50% working
interest owner. On leasehold acreage, UPRC does not have the right to
participate in the well but will retain a royalty interest that will result in a
total royalty burden of 25%. As compensation for committing its acreage position
to the Company, UPRC was granted warrants to purchase two million shares of the
Company's Common Stock. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Development, Acquisition and
Exploration."
 
     Drilling. The Company began drilling operations in Wattenberg in early
1991. From 1991 to December 1993, the Company expended $151.1 million to drill
667 wells, of which 323 were drilled in 1993. At yearend, 609 of these wells
were producing, 51 were in various stages of drilling and completion and seven
were dry holes.
 
     The size of the Wattenberg drilling program has resulted in numerous
advantages. The Company acts as operator on all its development sites in the
Wattenberg Field and much of the acreage is held by production. As a result, the
Company has significant operational control over the timing of the development
program. The actual drilling locations and schedule are selected to minimize
costs associated with rig moves, surface facilities, location preparation and
gathering system and pipeline connections and to evaluate and quantify
incremental reserve potential across the acreage position.
 
                                       15

     The Company's success in continuing to reduce its costs of drilling and
operations, as well as applying new technology, will be important to the full
development of its undeveloped acreage in Wattenberg. The Company has selected
procedures for drilling and completing wells that it believes maximize
recoverable reserves and economics. The Company has also been able to reduce its
costs of drilling, completing and operating wells significantly by negotiating
favorable prices with suppliers of drilling and completion services because of
the size of its drilling program. These cost reductions often allow the Company
to earn an attractive rate of return even on lower reserve wells. The reductions
have been achieved by several methods. One of the most significant is the
formation of alliances with selected vendors who work with Company personnel to
improve coordination and reduce both parties' costs. The resultant reductions
are credited wholly or in large part to the Company while vendors' margins are
maintained or increased.
 
     In addition to cost reduction, the Company seeks to employ new technology
or to creatively apply existing technology to reduce costs or to produce
reserves that would otherwise remain unrecovered. One example is the drilling of
four or more wells from a single drilling pad in residential areas, under
reservoirs and on inaccessible acreage.
 
     The Codell formation, which is the primary objective of the drilling, is a
blanket siltstone formation that exists under much of the Wattenberg acreage at
depths of 6,700 to 7,500 feet. Codell reserves have a high degree of
predictability due to uniform deposition and gradual transition from high to low
gas/oil ratio areas. The Company generally dually completes the Niobrara chalk
formation, which lies immediately above the Codell, to enhance drilling
economics. The Codell/Niobrara wells produce most prolifically in the first six
to twelve months, after which production declines to a fraction of initial
rates. More than half of a typical well's reserves are recovered in the first
three years of production. As a result, each well contributes significantly more
production in its first year than in subsequent years. However, the declining
production of individual wells is expected to be offset by continuing
development drilling.
 
     During 1992 and 1993, the Company expanded its drilling targets to include
both deeper and shallower formations. The J sand lies approximately 400 feet
below the Codell. It is a low permeability sandstone generally found to be
productive throughout the DJ Basin with performance varying proportionately with
porosity and thickness. The Dakota formation lies approximately 150 feet below
the J sand. It is a low permeability sand occasionally naturally fractured with
less predictable commercial accumulations and varied performance results. The
Sussex formation is at average depths of 4,500 feet. The Sussex sands were
deposited as bars and exhibit variable reservoir quality with a moderate degree
of predictability.
 
     Because the Codell, Niobrara and J formations are continuous reservoirs
over a large portion of the DJ Basin, the Company believes that drilling in the
Wattenberg Field is relatively low risk. In addition, the Company has compiled a
comprehensive geologic and production database for approximately 12,000 wells
within a 4,350 square mile area between Denver and the Wyoming border and has
had considerable success in predicting variations in thickness, porosity,
gas/oil ratios and productivity. Of the 667 wells drilled between 1991 and 1993,
only seven have been dry holes. Dry holes cost an average of only $65,000 per
well. The average net cost of a completed well approximated $193,000 during 1993
with only 30 days usually elapsing between spud date and initial production.
 
     CHEYENNE. During 1993, 29 wells were placed on stream in a shallow gas
producing area on the northeast flank of the DJ Basin. This project, known as
the Cheyenne Project, began with the acquisition of five shut-in gas wells in
1990 when the Company determined that it could capitalize on new open access
rules of the Federal Energy Regulatory Commission ("FERC") by constructing a
gathering system to transport gas to a nearby interstate pipeline. After
acquiring almost 50,000 acres of leases in the area and selling an approximate
27.5% interest to other parties on a promoted basis, the Company has drilled 54
successful wells and six dry holes in the area and constructed a gathering
system having a capacity of 10 MMcf per day to transport the gas to the
interstate pipeline. The Company currently operates 61 wells in this area that
produce from the Niobrara formation and plans to drill approximately 20
additional wells during 1994.
 
                                       16
   18
 
                                 EAST WASHAKIE
 
     During 1993, the Company initiated a major project to apply the
cost-cutting and improved drilling and completion techniques learned in the
Wattenberg Field to develop fluvial Mesaverde sands in the eastern Washakie
Basin. An eleven well pilot project was completed in 1993 to test drilling and
completion techniques and confirm cost estimates. A second drilling program is
currently being initiated. After final evaluation of the drilling, the Company
may initiate a large scale drilling program in this area upon completion of a
required environmental impact statement. The environmental impact statement was
filed in October 1993, and clearance is currently expected in the second half of
1994. Depending on the timing of environmental clearance and continued
evaluation of drilling results, the Company expects to drill up to 60 wells in
East Washakie during 1994.
 
     Since the mid-1980's, the Company's properties in the Barrel Springs Unit
and the Blue Gap Field of southern Wyoming, together with its gas gathering and
transportation facilities there, have been one of its most significant assets.
See "-- Properties" and "-- Gas Management." The Company currently operates 128
wells in this area and holds up to 1,200 potential drilling locations, 98 of
which were classified as proved undeveloped at yearend 1993. The Company
believes that more than half of the potential locations may ultimately prove
attractive to develop. The Company currently holds interests in 95,000 gross
(76,000 net) undeveloped acres in the Washakie Basin. This includes 36,000 gross
(32,000 net) undeveloped acres added during 1993.
 
                                 WESTERN SLOPE
 
     During 1993, the Company initiated the Western Slope Project by
establishing a sizable position in the Piceance Basin on the western slope of
Colorado and in the Uinta Basin in northeastern Utah. The Company formed the
53,000 acre Hunter Mesa Unit in the southeast corner of the Piceance Basin.
Through purchases and farmouts, the Company obtained a majority interest and
acts as unit operator. Immediately adjacent to the Hunter Mesa Unit, a 100%
working interest was purchased in the 26,000 acre Divide Creek Unit for $6.2
million. The acquisition of this Unit, which has six wells producing from the
Mesaverde and Cameo Coal formations, added 17.6 Bcf of proved gas reserves as
well as an established operating base. Near yearend, the Company also purchased
interests in 122 producing wells, 29 non-producing wells and 69 proved
undeveloped locations. In total, this purchase included 55,000 net acres in
various fields in the Piceance and Uinta Basins.
 
     Through these purchases, farmouts and a leasing program, the Company
currently holds acreage with up to 1,000 potential drilling locations, of which
the Company believes 40% could ultimately prove to be attractive to develop. Of
these locations, 101 were classified as proved undeveloped at yearend 1993. The
development of the Mesaverde sands in the Piceance Basin began with the spudding
of the initial test well near the end of 1993. The development will continue
with a 10 well test program during 1994 to confirm cost estimates and improved
recovery techniques. If successful, the Company may drill up to 30 wells in 1994
and approximately 100 wells per year thereafter. The Company's ability to
continue to develop the Piceance Basin is in part dependent on arranging
gathering and transportation at a reasonable cost. The company is exploring
options for gathering and transporting future gas production, including the
possibility of constructing Company owned facilities.
 
                               OTHER DEVELOPMENT
 
     At the end of 1992, the Company acquired interests in four large producing
fields in central Wyoming from a major oil company at a cost of $56.1 million.
Two of the fields, the Hamilton Dome and Riverton Dome Fields, are operated by
the Company. During 1993, the Company evaluated opportunities in the fields and
instituted programs to enhance production in the latter part of the year. In the
Hamilton Dome Field, improvement of the water injection system and completion of
two new wells increased daily production 8% above the levels projected at the
time of the acquisition. A third well should be completed in the second quarter
of 1994. In the Riverton Dome Field, workovers and recompletions increased daily
production over 10% above the levels projected at the time of the acquisition.
Additional workovers and development drilling
 
                                       17
   19
 
are scheduled for both fields during 1994. The Company is attempting to work
with the major oil companies that operate the other two fields purchased, both
of which are producing slightly below acquisition projections.
 
   
     The Company operates the Adair waterflood property in Gaines County, Texas,
which it purchased in September 1991. Initial development of the Adair Unit in
1992 cost approximately $1.7 million net to the Company. Based on production
response from the initial phase of development, the Company spent an additional
$.4 million in 1993 to conduct a pilot program which reduced well spacing on a
portion of the Unit. This program increased the unit production from 150 barrels
per day to 260 barrels per day. The Company plans to spend an additional $1.1
million to implement an infill development program throughout the Unit.
    
 
     In the Giddings Field in Southeast Texas, the Company has undertaken a
horizontal drilling program to further exploit existing properties in the area.
During 1993, the Company spent $2.2 million to re-enter or drill 10 wells, of
which nine were completed and one abandoned. The Company is encouraged by the
results to date and plans to increase its expenditures in the field during 1994.
At yearend, 25 locations were classified as having proved undeveloped reserves.
 
ACQUISITION PROGRAM
 
     The Company believes that acquisitions continue to be an attractive method
of increasing its reserve base and cash flow. In its acquisition efforts, the
Company plans to focus on purchasing properties that strengthen its strategic
position and complement its large-scale gas development projects in the Rockies,
as well as provide opportunities to establish meaningful positions in new areas.
From 1983 through 1993 the Company, on behalf of itself, its affiliates and
other investors, purchased oil and gas properties and related assets with an
aggregate cost of nearly $650 million. The Company actively seeks to acquire
incremental interests in existing properties, acreage with development
potential, gas gathering, transportation and processing facilities and related
assets, particularly in proximity to existing properties. Purchases of
incremental interests or adjacent properties are generally small in size but in
aggregate represent a sizeable opportunity that is relatively easy to pursue.
 
     Due to its rate of return requirements and the high cost of pursuing
potential acquisitions, the Company generally prefers negotiated transactions to
auctions. Complex transactions involving legal, financial or operational
difficulties have frequently permitted purchase of assets at favorable prices.
Past acquisitions of corporations laid the groundwork for the Wattenberg hub,
and may in the future provide opportunities to expand in other areas.
Acquisitions of incremental interests are being given particular emphasis to
take advantage of systems and operational knowledge already in place. The
Company has extensive experience in completing numerous types of acquisitions
using varied financing sources in addition to internal cash flow.
 
     During 1993 domestic acquisitions having a total cost of $51.0 million were
completed, primarily to strengthen Wattenberg and establish two new hubs that
the Company believes have the potential to develop into large scale gas
development projects. In Wattenberg a series of purchases added nearly 9 million
BOE of proved reserves at a net cost of under $3.50 per barrel as well as
several pipeline and processing facilities that complement the Company's
existing gathering systems. In the largest of these acquisitions, the Company
paid $19.7 million and, after an exchange of interests with a third party,
acquired an approximate 80% working interest in 153 producing wells and 284
undeveloped locations having total proved reserves estimated to exceed 7 million
BOE. A portion of the value of the transaction lay in the large volume of
undedicated gas located in close proximity to the Company's gas lines.
 
     In the Washakie Basin, the Company expended over $7.8 million to acquire a
25% incremental interest in its Barrel Springs properties and interests in 44
producing wells and 7 undeveloped locations, as well as a gathering system that
expands the existing gathering infrastructure in the area. These acquisitions
added approximately 3.6 million BOE of proved reserves and, together with an
active leasing program, formed the basis for the East Washakie Project, the
Company's second operating hub in the Rockies. See "-- Development -- East
Washakie."
 
     Through three purchase transactions, as well as farmouts and leasing, the
Company established a substantial position in the Piceance and Uinta Basins
during 1993, laying the foundation of the Western Slope
 
                                       18

Project, a third gas development hub in the Rockies. A $6.2 million purchase
gave the Company a 100% working interest in the 26,000 acre Divide Creek Unit in
the southeast Piceance Basin. The Company also formed the adjacent 53,000 acre
Hunter Mesa Unit and through purchases and farmouts obtained a majority working
interest position and became unit operator. Near yearend the Company also
acquired interests in 122 producing wells, 29 non-producing wells and 69 proved
undeveloped locations in various fields in the Uinta and Piceance Basins. See
"-- Development -- Western Slope."

GAS MANAGEMENT
 
   
     General. The Company expanded its gas gathering and processing capacity
during 1993 with the construction of additional gathering facilities and
expansion of the Roggen plant in Wattenberg, as well as the acquisition of
additional gas facilities in Wattenberg and in Wyoming. By yearend, operated
processing capacity had increased to more than 80 MMcf per day and gathering
system capacity was increased to more than 200 MMcf per day, while marketed net
volumes reached 100 MMcf per day. The gas management unit complements the
Company's development and acquisition activities by providing additional cash
flow and enhancing returns. The segment is also increasingly profitable in its
own right. During 1993, gross margin increased by approximately 23% to $10
million. See "-- Customers and Marketing."
    
 
     Colorado Facilities. The largest concentration of gas facilities is in the
Wattenberg area. These facilities include two major gathering systems, the
Enterprise system and Energy Pipeline, the Roggen processing plant, and a number
of minor facilities. By yearend 1993, the Roggen plant capacity had reached 60
MMcf per day. During the fourth quarter of 1993, average throughput had reached
54 MMcf per day. The plant is expected to process gas from currently undeveloped
locations, new third party sources and permanently released locations on acreage
acquired from Amoco, plus additional gas from current suppliers. Gas developed
through the UPRC joint venture is not dedicated to a processing plant and will
significantly increase future volumes of gas available to be processed in the
Company's facilities.
 
     The gas produced from the majority of the new Wattenberg wells drilled on
acreage acquired from Amoco is dedicated for the life of the lease to Amoco's
Wattenberg gas processing plant. If Amoco were unable to process Company
production at its plant for any reason, including a shut-down of the plant, it
would have a short-term adverse impact on the Company. The Company has expanded
its processing facilities in Wattenberg in order to process Company and third
party gas that is not dedicated to Amoco. The Company
 
                                       19
   21
 
intends to continue to expand its facilities during 1994 to handle additional
gas developed through continued drilling activity. These facilities will also
enable the Company to partially mitigate the effects of significant downtime at
the Amoco plant.
 
     At the Roggen plant, gas is processed to recover gas liquids, primarily
propane and a butane/gasoline mix, from gas supplied by the Company and third
parties. The liquids are then sold separately from the residue gas. The liquids
are marketed to local and regional distributors and the residue gas is sold to
utilities, independent marketers and end users through an intrastate system and
the Colorado Interstate Gas ("CIG") pipeline. A liquids line permits the direct
sale of Roggen's liquids products through an Amoco line to the major interchange
at Conway, Kansas. In addition, Phillips Petroleum began reactivation of an old
interconnect, which should be operational by the end of the second quarter of
1994, which will connect the Roggen plant to the Phillips Powder River liquids
pipeline.
 
     The Company's Wattenberg gathering systems include over 600 miles of
pipeline that collect, compress and deliver gas from over 1,400 wells to the
Roggen plant. During 1993, the Company substantially increased the capacity of
its gathering systems through the expansion of existing facilities and the
acquisition of new facilities. The Company also completed the second phase of
the Enterprise system during 1993. Enterprise collects a portion of the
Company's gas produced from acreage acquired from Amoco and delivers it to the
Amoco Wattenberg plant. Enterprise includes 26 miles of 20" diameter trunk and
29 miles of associated lateral gathering lines connecting 20 of the Company's
existing central delivery points. As a result of the completion of the second
phase, the Enterprise system has the capacity to deliver 75 MMcf per day to the
Amoco Wattenberg plant.
 
     During 1993, the Company also expanded its gathering system by constructing
a nine mile 16" pipeline loop on the western portion of its Energy Pipeline
system, which came on line in October 1993. This expansion provides pressure
relief and additional capacity for further development in the area. In addition,
the Company acquired a pipeline that expands its gathering capacity to the north
of the Roggen plant, which may be converted to a residue line allowing for the
delivery of residue gas from the tailgate of the Roggen plant to the Williams
Natural Gas System.
 
     The Company has negotiated a transportation arrangement with CIG that, in
conjunction with the gathering fees to be charged on the Enterprise system,
allows the delivery of gas to the Amoco Wattenberg plant at a favorable rate. In
addition to reducing the Company's exposure to future escalation in gathering
costs applicable to the Company's production, Enterprise provides an enhanced
degree of operational control. Because the Enterprise system interconnects with
the Company's other Colorado facilities, the Roggen plant and other plants in
the area can serve as a backup for processing a portion of the Company's gas in
the event of any curtailment at the Amoco Wattenberg plant. While shut downs of
Amoco's plant reduce the Company's production, diversion of gas to the Roggen
plant and, to a lesser degree, two other plants in the area, enabled the Company
to produce significant volumes that would have otherwise been curtailed.
 
     Given the continued expansion of the Company's drilling program in 1994 and
beyond and the potential for third party connections, the Company is continuing
to explore opportunities to expand its Wattenberg gas facilities. Subsequent to
yearend, the decision was made to double the Company's processing capacity
through the construction of a new plant on the west side of the field. The new
plant is scheduled to be operational in late 1994.
 
     Wyoming Facilities. The Company operates two pipeline systems in Wyoming
that enhance its ability to market gas produced from its properties in the
Washakie Basin. Wyoming Gathering and Production Company ("WYGAP") gathers gas
produced from 53 operated wells in the Barrel Springs Unit. The system has a
capacity of 26 MMcf per day. Throughput averaged 10 MMcf and 14 MMcf per day
during 1992 and 1993, respectively. WYGAP delivers gas to Western Transmission
Corporation ("Westrans"), a Company-owned interstate pipeline system which
operates under FERC jurisdiction. At the beginning of 1993, the Company assumed
operations of CIG's Carbon County Blue Gap gathering system pursuant to a lease.
The Company has exercised an option to acquire the system subject to regulatory
approval. The Company also purchased Blue Gap gathering facilities formerly
owned by Williams Field Services. Both systems extend the Company's
transportation capabilities to the south.
 
                                       20
   22
 
     The Westrans system consists of a 26-mile main pipeline, a smaller 9.2-mile
line and related gathering facilities. The system gathers and transports gas
under open access transportation service agreements on an interruptible basis.
The main line extends from the Washakie Basin area of Carbon County, Wyoming to
connections with Williams' and CIG's interstate pipelines in Sweetwater County,
Wyoming. Gas transported on Westrans also has access to California markets
through the Kern River Pipeline which was completed in February 1992 via
interconnects with CIG and Williams. Westrans is located near several other
interstate pipelines, providing the potential for additional interconnects that
offer alternative transportation routes to end markets. In addition to the gas
from WYGAP, which accounts for over 90% of its volumes, Westrans transports
volumes from other operated wells and third parties. The capacity of Westrans is
65 MMcf per day. Throughput volumes generally vary from 13 to 20 MMcf per day.
Daily throughput averaged 15 MMcf during 1992 and 1993. If the planned
acceleration of drilling in East Washakie occurs, volumes of gas on the
Company's gas pipeline in the area may be substantially increased. As the East
Washakie Project progresses, the Company expects to further expand its gathering
network in the area.
 
     Other Facilities. The Company expanded its gathering system in southern
Nebraska during 1993 to gather gas produced from newly developed Cheyenne County
properties for delivery to various markets accessible through an interstate
pipeline. The Cheyenne system includes 9.5 miles of 4" to 6" trunkline and 6
miles of 3" lateral gathering lines. During the fourth quarter of 1993,
throughput averaged 3 MMcf per day of gas from 60 producing wells. Included in
the December 1992 acquisition of Wyoming properties was a gas processing plant
in Fremont County, Wyoming. The plant has a 20 MMcf per day capacity with
current throughput of 8 MMcf per day from the 28 producing wells in the Riverton
Dome Field.
 
     In conjunction with the growing level of acquisition and development
activity in the Western Slope Project, the Company is actively exploring
alternatives to gather and transport future gas production, including the
possible construction of a Company-owned gathering and transportation line.
Traditionally, the lack of sufficient pipeline capacity has been a major
deterrent to development in the Piceance Basin.
 
INTERNATIONAL ACTIVITIES
 
     The Company's strategy internationally is to develop projects that have the
potential for a major impact in the future. The Company attempts to structure
the projects to limit its financial exposure and mitigate political risk by
minimizing financial commitments in the early phases of a project and seeking
industry partners and investors to fund the majority of the equity capital. A
wholly owned subsidiary of the Company, SOCO International, Inc., is the holding
company for all the Company's international operations. During 1993, the Company
purchased from Edward T. Story, President of SOCO International, the 10% of SOCO
International held by him and canceled Mr. Story's option to purchase an
additional 20% of the company. In connection with the purchase, the Company
granted Mr. Story an option to purchase 10% of the currently outstanding shares
of SOCO International, which is financed primarily by Company loans, through
April 1998 for $600,000. The option price is subject to adjustment in certain
circumstances.
 
     Russian Joint Venture. In early 1993, the Company formed Permtex, a joint
drilling venture with Permneft, a Russian oil and gas company, to develop four
major proven oil fields located in the Volga-Urals Basin of the Perm Region of
Russia, approximately 800 miles east of Moscow. During 1993, Permtex was
registered by the Russian authorities, representing governmental approval of the
terms of the joint venture and authorization for Permtex to commence business.
In early 1994, the Company executed a finance and insurance protocol with OPIC,
an agency of the United States government that provides financing and political
risk insurance for American investment in developing countries, related to the
financing of Permtex.
 
     Permtex holds exploration and development rights to over 300,000 acres in
the Volga-Urals Basin. The contract area contains four major fields and four
minor fields as well as a number of prospects. The Company estimates that the
four major fields could ultimately produce 115 million barrels of oil. The major
fields have been delineated through 45 previously drilled wells, none of which
had been placed on production as of yearend 1993. It is anticipated that 25 of
the existing wells will be placed on production, of which four should go on
stream in the first half of 1994, and that 400 additional development wells will
be drilled over the next
 
                                       21
   23
 
five to ten years. The joint venture will primarily utilize Russian personnel
and equipment and Western technology under joint Russian/American management.
 
     As of March 1, 1994, the Company holds a 28.1% interest in Permtex, after
giving effect to the purchases by each of Command, the Company's Australian
affiliate, and Holland Sea Search NV ("HSSH"), a Dutch affiliate of Command, of
6.25% interests in Permtex. Recently, a major Japanese trading company has also
committed to purchase a 10 to 20% interest in Permtex, which would reduce the
Company's interest to 20.6% if the full amount is purchased.
 
     Command Petroleum Holdings NL. In May 1993, the Company purchased 42.8% of
the outstanding shares of Command for approximately $18.2 million. At the time
of the purchase, Thomas J. Edelman, President of the Company, Edward T. Story,
President of SOCO International, and two other designees were elected to
Command's eight-person board of directors. Command is an exploration and
production company based in Sydney, Australia and listed on the Australian Stock
Exchange. Following a private placement of equity securities in early 1994,
Command had working capital of $35 million and no debt. Its current market
capitalization approximates US$150 million. Command currently holds interests in
more than 20 exploration permits and production licenses primarily in the
Southwestern Pacific Rim including Australia and Papua New Guinea. Until
recently, Command held a 28.7% interest in HSSH, a publicly traded Dutch
exploration and production company whose primary asset is an interest in the
North Sea's Markham gas field. After yearend 1993, Command increased its
position in HSSH to nearly 48%. Recently, Command purchased a 6.25% interest in
Permtex, acquired an interest in an offshore Tunisian permit operated by
Marathon Oil Company and acquired an 11.4% interest in the East Shabwa Contract
Area in Yemen. Command funded the expenditures with a portion of a $16.4 million
privately placed equity offering which reduced the Company's ownership to 35.7%.
If as expected, all of Command's warrants expiring in November 1994 are
exercised, the Company's ownership would be decreased to 29.6%.
 
     The Company believes that Command's exploration expertise, experienced
technical staff and inventory of prospects complement the Company's acquisition
and development expertise and position the Company to play a larger role in
overseas development of oil and gas reserves. In addition, Command and HSSH
provide access to international capital markets which could provide additional
sources of financing for international projects.
 
     Mongolia. The Company further expanded its international efforts by
entering into a production sharing agreement with Mongol Petroleum Company, the
national oil company of Mongolia. The Company believes this agreement is the
first such contract ever awarded by Mongolia. The agreement covers 11,400 square
kilometers, or approximately 2.8 million gross acres, in the Tamstag Basin of
northeastern Mongolia. In addition, the Company received a right of first
refusal from Mongol Petroleum for the adjacent block which covers 11,130 square
kilometers. As a consequence, the Company controls over 5 million acres in this
basin which, although previously unexplored and remote from existing markets, is
highly prospective. These concessions offset the Hailar Basin of China, a
portion of which is included in the China National Petroleum Corporation's round
of invitations for bidding in 1994. During 1993, the Company initiated seismic
work to broadly define the subsurface and this work is expected to continue into
1995.
 
     Tunisia. During 1993 the Company completed its 400 kilometer seismic
acquisition program in the Fejaj Permit area of central Tunisia. The permit area
encompasses approximately 1.2 million gross acres and is predominately onshore,
with a small portion extending into the Gulf of Gabes. After the Company
integrates the newly acquired seismic work with over 1,400 kilometers of
reprocessed data and extensive geological field information, the Company will
seek industry partners for a 1995 exploratory well.

(a) Gas production is converted to oil equivalents at the rate of 6 Mcf per
    barrel except for Thomasville production which through 1992 was converted
    based on its price equivalency to the Company's other gas. Average gas
    prices exclude Thomasville production. See "Management's Discussion and
    Analysis of Financial Condition and Results of Operations."
(b) Sales of natural gas liquids are included in gas revenues. Gas revenues for
    the year ended December 31, 1989 and 1990 include nonrecurring receipts of
    $183,000 and $219,000, respectively, in settlement of contract claims, which
    have been excluded from average sales price computations.
(c) The Company estimates that its composite net wellhead prices at December 31,
    1993 were approximately $2.11 per Mcf of gas and $11.49 per barrel of oil.

DRILLING RESULTS
 
     The following table sets forth information with respect to wells drilled
during the past three years. The information should not be considered indicative
of future performance, nor should it be assumed that there is necessarily any
correlation between the number of productive wells drilled, quantities of
reserves found or economic value. Productive wells are those that produce
commercial quantities of hydrocarbons whether or not they produce a reasonable
rate of return.

     As of December 31, 1993, the Company had 61 gross (50.9 net) development
wells in progress. Between yearend and February 28, 1994, the Company spudded
118 wells. At that date 135 gross (116.7 net) wells, including wells in progress
at yearend, had been completed, two wells (1.5 net) had been abandoned and 42
gross (36.3 net) development wells were in progress.
 
FIELD OPERATIONS
 
     In its capacity as operator, the Company supervises day-to-day field
activities, generally employing a combination of its personnel and contract
pumpers. The Company maintains eight district field offices and one division
office.
 
     As operator, the Company charges overhead fees to all working interest
owners according to the applicable operating agreements. As of the end of 1991,
1992 and 1993, respectively, the Company operated 1,442, 1,745 and 2,176 wells.
The Company received overhead reimbursements for operations and drilling of
$10.1 million, $12.9 million and $15.5 million during 1991, 1992 and 1993,
respectively (including reimbursements attributable to the Company's interest).
The increase in reimbursements is attributable to the increase in operated
drilling and producing wells and contractual escalations. Based on the time
allocated to operations, these reimbursements in aggregate generally have
exceeded the costs of such activities.
 
PROPERTIES
 
     The Company's reserves are concentrated in several major producing areas.
These include the Wattenberg Field in Colorado, central and southern Wyoming,
the Piceance and Uinta Basins in the Western Slope of Colorado and Utah, the
Giddings area in South Texas, the Spraberry Trend in West Texas, waterflood
units in Texas, and the Appalachian Basin in eastern Ohio and Pennsylvania.
 
     At December 31, 1993, the Company had interests in 5,122 gross (2,187 net)
producing oil and gas wells located in 15 states and in the Gulf of Mexico. As
of December 31, 1993, estimated proved reserves totalled 31.9 million barrels of
oil and 430.1 Bcf of gas. In addition to its oil and gas reserves, the Company
holds interests in nine gas transportation and processing facilities. See
"-- Gas Management."

     Significant Properties. Although the Company's properties are widely
dispersed geographically, emphasis has been placed on establishing hubs in
certain producing basins. Interests in five producing areas accounted for
approximately 90% of Pretax PW10% Value at December 31, 1993. This concentration
of assets results in economic efficiencies in the management of assets and
permits identification of complementary acquisition candidates. Summary
information regarding the five most significant properties is set forth below.

     The quantities and values in the preceding tables are based on prices in
effect at December 31, 1993, averaging $11.49 per barrel of oil and $2.11 per
Mcf of gas. Price reductions decrease reserve values by lowering the future net
revenues attributable to the reserves and will reduce the quantities of reserves
that are recoverable on an economic basis. Price increases have the opposite
effect. Any significant decline in prices of oil or gas could have a material
adverse effect on the Company's financial condition and results of operations.
 
     Proved developed reserves are proved reserves that are expected to be
recovered from existing wells with existing equipment and operating methods.
Proved undeveloped reserves are proved reserves that are expected to be
recovered from new wells drilled to known reservoirs on undrilled acreage for
which the existence and recoverability of such reserves can be estimated with
reasonable certainty, or from existing wells where a relatively major
expenditure is required to establish production.
 
     Future prices received for production and future production costs may vary,
perhaps significantly, from the prices and costs assumed for purposes of these
estimates. There can be no assurance that the proved reserves will be developed
within the periods indicated or that prices and costs will remain constant. With
respect to certain properties that historically have experienced seasonal
curtailment, the reserve estimates assume that the seasonal pattern of such
curtailment will continue in the future. There can be no assurance that actual
production will equal the estimated amounts used in the preparation of reserve
projections.
 
     The present values shown should not be construed as the current market
value of the reserves. The 10% discount factor used to calculate present value,
which is specified by the Securities and Exchange Commission ("SEC"), is not
necessarily the most appropriate discount rate, and present value, no matter
what discount rate is used, is materially affected by assumptions as to timing
of future production, which may prove to be inaccurate. For properties operated
by the Company, expenses exclude the Company's share of overhead charges. In
addition, the calculation of estimated future net revenues does not take into
account the effect of various cash outlays, including, among other things,
general and administrative costs and interest expense.
 
     There are numerous uncertainties inherent in estimating quantities of
proved reserves and in projecting future rates of production and timing of
development expenditures. The data in the above tables represent estimates only.
Oil and gas reserve engineering must be recognized as a subjective process of
estimating underground accumulations of oil and gas that cannot be measured in
an exact way, and estimates of other engineers might differ materially from
those shown above. The accuracy of any reserve estimate is a function of the
quality of available data and engineering and geological interpretation and
judgment. Results of drilling, testing and production after the date of the
estimate may justify revisions. Accordingly, reserve estimates are often
materially different from the quantities of oil and gas that are ultimately
recovered.
 
     Netherland, Sewell & Associates, Inc. ("NSAI"), independent petroleum
consultants, prepared estimates of or audited the Company's proved reserves
which collectively represent more than 80% of Pretax PW10% Value as of December
31, 1993. Approximately 38% of the yearend Pretax PW10% Value was estimated
internally by the Company and 62% was estimated independently by NSAI. No
estimates of the Company's reserves comparable to those included herein have
been included in reports to any federal agency other than the SEC.
 
     Producing Wells. The following table sets forth certain information at

CUSTOMERS AND MARKETING
 
     The Company's oil and gas production is principally sold to refiners and
others having pipeline facilities near its properties. Where there is no access
to gathering systems, crude oil is trucked to storage facilities. In 1992 and
1993, Amoco accounted for approximately 27% and 12% of revenues, respectively,
as the result of the contractual dedication, which terminated at the end of
1993, of a portion of the Company's natural gas and natural gas liquids produced
from certain of its Wattenberg acreage. Historically, this arrangement provided
for average prices in excess of spot due to participation in certain fixed price
contracts, many of which are expected to expire over the next two years. The
Company exercised its option to release its natural gas and natural gas liquids
and began marketing its production beginning January 1, 1994. The Company
believes, however, that it can obtain pricing comparable to that which would
have been obtainable through Amoco. The marketing of oil and gas by the Company
can be affected by a number of factors that are beyond its control and whose
future effect cannot be accurately predicted. The Company does not believe,
however, that the loss of any of its customers would have a material adverse
effect on its operations.
 
     In addition to marketing a significant portion of its own gas, in 1992 the
Company initiated an effort to supplement its cash flow through the purchase and
resale of gas owned by third parties. Gross margins during 1992 and 1993 from
third party marketing activities was $.6 million and $1.2 million, respectively,
as average third party volumes increased from 58.7 to 89.9 MMcf per day. The
Company expects to continue increasing its role in third party gas marketing.
 
     In June 1991, the Company entered into a contract to supply gas to a
cogeneration facility through August 2004. The contract calls for the Company to
supply 10,000 MMBtu per day. This plant, which requires up to 24,500 MMBtu per
day of gas, began operations in 1989 and is located at a manufacturing facility
in Oklahoma City. The facility has firm fifteen-year sales agreements with a
utility company for electricity and with a tire manufacturer for steam. The
effect of this contract depends on market prices for gas and its choice of
alternative sources of gas (including the spot market) to meet its supply
commitments. Gross margin generated from the contract was approximately $1.5
million for both 1991 and 1992. A contractual limitation of the contract sales
price and rising gas purchase costs resulted in a net loss of $267,000 on the
contract during 1993. At present gas price levels, the Company foresees
continued negative or breakeven margins for this contract through July 1994. At
that time, a change in the pricing formula should result in improved margins.
 
   
                              DESCRIPTION OF NOTES
    
 
   
     The Notes are to be issued under an Indenture to be dated as of April 1,
1994 (the "Indenture") between the Company, as issuer, and Texas Commerce Bank
National Association, as trustee (the "Trustee"), a copy of which is filed as an
exhibit to the Registration Statement of which this Prospectus is a part. The
terms of the Indenture are governed by certain provisions contained in the Trust
Indenture Act of 1939, as amended (the "Trust Indenture Act"). The following
summaries of certain provisions of the Indenture do not purport to be complete,
and where particular provisions of the Indenture are referred to, such
provisions, including the definitions of certain capitalized terms used in this
Prospectus, are incorporated by reference as a part of such summaries, which are
qualified in their entirety by reference to the provisions of the Indenture. The
section ("Section") and article ("Article") references appearing below are to
sections and articles of the Indenture.
    
 
GENERAL
 
   
     The Notes will be unsecured subordinated obligations of the Company, will
mature on March 31, 2001 and will be in the aggregate principal amount of
$100,000,000 ($115,000,000 aggregate principal amount if the Underwriters'
over-allotment option is exercised in full). The Notes will bear interest from
the date of issuance at the rate per annum shown on the cover page of this
Prospectus. Interest will be payable semi-annually on March 31 and September 30
of each year, commencing September 30, 1994, to the persons in whose names such
Notes (or any predecessor Notes) are registered at the close of business on the
March 15 or September 15 preceding such Interest Payment Date (Sections 301 and
307).
    
 
                                       27
   29
 
   
     Principal of and premium, if any, and interest on the Notes will be
payable, and the Notes will be convertible and may be presented for transfer and
exchange, at the office or agency maintained by the Company for such purposes,
which will initially be the office of the Trustee located at 80 Broad Street,
Fourth Floor, New York, New York 10004. However, at the option of the Company,
payment of interest on the Notes may be made by check mailed to the address of
persons entitled thereto as shown in the register of the Security Registrar. No
service charge will be made upon any registration of transfer or exchange of the
Notes, but the Company may require payment of a sum sufficient to cover any tax
or other governmental charge payable in connection therewith.
    
 
   
     The Indenture does not limit the incurrence of additional indebtedness,
including Senior Indebtedness, by the Company.
    
 
   
CONVERSION RIGHTS
    
 
   
     The Notes will be convertible, in whole or from time to time in part (in
denominations of $1,000 or integral multiples thereof), at the option of the
holder thereof, into Common Stock of the Company, initially at the conversion
price stated on the cover page hereof, at any time prior to maturity, unless
previously redeemed by the Company. In the case of Notes called for redemption,
conversion rights will terminate at the close of business on the fifth business
day preceding the Redemption Date. Notwithstanding anything to the contrary in
the foregoing, the Notes will not be convertible at any time when payments on
the Notes are prohibited under the subordination provisions of the Indenture as
described under "-- Subordination of Notes" (Section 1201).
    
 
   
     If the Company, by dividend or otherwise, declares or makes a distribution
on its Common Stock of the type referred to in clause (iv) or (v) below, the
holder of each Note, upon the conversion thereof subsequent to the close of
business on the date fixed for the determination of stockholders entitled to
receive such distribution and prior to the effectiveness of the conversion price
adjustment in respect of such distribution pursuant to clause (iv) or (v) below,
will be entitled to receive for each share of Common Stock into which such Note
is converted the portion of the evidences of indebtedness, shares of capital
stock, cash and other assets so distributed applicable to one share of Common
Stock; provided, however, that the Company may, with respect to all holders so
converting, in lieu of distributing any portion of such distribution not
consisting of cash or securities of the Company, pay such holder cash in an
amount equal to the fair market value thereof, as determined in good faith by
the Board of Directors (Section 1201).
    
 
   
     The conversion price will be subject to adjustment in certain events,
including: (i) dividends (and other distributions) payable in Common Stock on
any class of capital stock of the Company; (ii) the issuance to all holders of
Common Stock of rights, warrants or options entitling them to subscribe for or
purchase Common Stock at less than the current market price (as provided in the
Indenture); provided, however, that if such rights, warrants or options are only
exercisable upon the occurrence of certain triggering events, then the
conversion price will not be adjusted until such triggering events occur; (iii)
subdivisions and combinations of Common Stock; (iv) distributions to all holders
of Common Stock of evidences of indebtedness of the Company, shares of any class
of capital stock, cash or other assets (including securities, but excluding
those dividends, rights, warrants, options and distributions referred to in
clauses (i) and (ii) above and excluding dividends and distributions exclusively
paid in cash up to the greater of (x) retained earnings of the Company on the
date such distribution or dividend was declared or (y) Net Income (as defined
below) of the Company during the four full fiscal quarters preceding the date
such distribution or dividend was declared, and other than in connection with a
tender offer or other negotiated purchase made by the Company or any Subsidiary
for all or a portion of the Common Stock); provided, however, that if any
rights, warrants or options in respect of which an adjustment is provided for in
this clause (iv) are only exercisable upon the occurrence of certain triggering
events, then the conversion price will not be adjusted until such triggering
events occur; (v) distributions consisting exclusively of cash (specifically
including distributions paid in cash up to the greater of (x) retained earnings
of the Company on the date such distribution or dividend was declared or (y) Net
Income of the Company during the four full fiscal quarters preceding the date
such distribution or dividend was declared, but excluding any cash distributions
for which an adjustment has been made pursuant to a preceding clause of this
paragraph) to all holders of Common Stock in an aggregate amount that, together
    
 
                                       28
   30
 
with (A) other all-cash distributions made within the preceding 12 months not
triggering a conversion price adjustment and (B) all Excess Tender Payments (as
defined below) in respect of each tender or exchange offer by the Company or any
Subsidiary for Common Stock concluded within the preceding 12 months not
triggering a conversion price adjustment, exceeds an amount equal to 20% of the
Company's deemed market capitalization on the date fixed for the determination
of stockholders entitled to receive such distribution (calculated as set forth
in the Indenture); (vi) issuances of Common Stock to an Affiliate for a net
consideration per share less than the current market price per share (other than
issuances of Common Stock under certain management benefit plans); and (vii)
payment of an Excess Tender Payment in respect of a tender or exchange offer by
the Company or any Subsidiary for Common Stock, if the aggregate amount of such
Excess Tender Payment, together with (A) the aggregate amount of any all-cash
distributions made within the preceding 12 months not triggering a conversion
price adjustment and (B) all Excess Tender Payments in respect of each tender or
exchange offer by the Company or any Subsidiary for Common Stock concluded
within the preceding 12 months not triggering a conversion price adjustment,
exceeds an amount equal to 20% of the Company's deemed market capitalization on
the expiration of such tender offer (calculated as set forth in the Indenture)
(Section 1204). For purposes of these conversion price adjustments, the term (i)
"Excess Tender Payment" means the excess of (A) the aggregate of the cash and
value of other consideration paid by the Company with respect to the shares
acquired in the tender or exchange transaction over (B) the market value of such
acquired shares after the completion of the tender or exchange offer (calculated
as set forth in the Indenture) and (ii) "Net Income" of any Person means the net
income of such Person net of non-cash charges taken as a result of accounting
changes required to be made by the Financial Accounting Standards Board after
the date of the Indenture.
 
   
     No adjustments in the conversion price are required for any dividend or
distribution referred to above if the holders may participate in the dividend or
distribution (on a basis determined in good faith to be fair by the Board of
Directors) and receive the same consideration they would have received if they
had converted the Notes (Section 1213).
    
 
   
     No adjustment of the conversion price will be required to be made until
cumulative adjustments amount to 1% or more of the conversion price as last
adjusted. In addition to the foregoing adjustments, the Company will be
permitted to make such reductions in the conversion price as it considers to be
advisable in order that any event treated for federal income tax purposes as a
dividend of stock or stock rights will not be taxable to the recipient (Section
1204).
    
 
   
     Subject to any applicable right of the holders to receive the Change of
Control Purchase Price (as described below), in the case of certain
consolidations or mergers to which the Company is a party or the transfer or
lease of the Company's properties or assets substantially as an entirety, each
holder has the right to convert each Note only into the kind and amount of
securities, cash and other property receivable upon the consolidation, merger,
transfer or lease by a holder of the number of shares of Common Stock into which
such Note might have been converted immediately prior to such consolidation,
merger, transfer or lease (assuming such holder of Common Stock is not a
Constituent Person and such holder failed to exercise any rights of election and
received per share the kind and amount of consideration received per share by a
plurality of non-electing shares) (Section 1211).
    
 
   
     Fractional shares of Common Stock will not be issued upon conversion, but,
in lieu thereof, the Company will pay a cash adjustment based upon the market
price of a share of Common Stock (Section 1203). Except as provided below, no
adjustment will be made upon a conversion of Notes for interest accrued thereon.
The Company's delivery to the holder of the fixed number of shares of Common
Stock into which the Note is convertible will be deemed to satisfy the Company's
obligation to pay the principal amount of the Note and all accrued interest that
has not previously been paid. If a Note is surrendered for conversion during the
period from the close of business on any Regular Record Date next preceding any
Interest Payment Date to the close of business on any Interest Payment Date,
then notwithstanding such conversion, interest payable in respect of the Note so
surrendered will be paid in cash to the person in whose name such Note is
registered at the close of business on such Regular Record Date, and (except in
the case of Notes with a Maturity Date prior to such Interest Payment Date) when
so surrendered for conversion, such Note must be accompanied by payment of a
    
 
                                       29
   31
 
amount equal to the interest thereon which the registered holder as of the close
of business on such Regular Record Date is to receive (Sections 307 and 1202).
 
   
SUBORDINATION OF NOTES
    
 
   
     The payment of the principal of and premium, if any, and interest on the
Notes is, to the extent set forth in the Indenture, subordinated in right of
payment to the prior payment in full of all Senior Indebtedness, whether now
outstanding or incurred in the future (Section 1301). Upon any payment or
distribution of assets of the Company to creditors upon any liquidation,
dissolution, winding up, assignment for the benefit of creditors or marshalling
of assets and liabilities or any bankruptcy, insolvency, receivership,
liquidation, reorganization or similar proceedings of the Company, the holders
of all Senior Indebtedness will first be entitled to receive payment in full of
all amounts due or to become due thereon before the holders of the Notes will be
entitled to receive any payment (other than any payment in the form of Permitted
Junior Securities) on account of the principal of or premium, if any, or
interest on the Notes, including payment of the Redemption Price and the Change
of Control Purchase Price of the Notes, and before the Notes may be converted
into Common Stock (Section 1302).
    
 
   
     No payment (other than any payment in the form of Permitted Junior
Securities) on account of principal of and premium, if any, or interest on the
Notes, including payment of the Redemption Price and the Change of Control
Purchase Price on the Notes, may be made, and the Notes may not be converted
into Common Stock, if a Payment Event of Default shall have occurred and be
continuing. In addition, no payment (other than any payment in the form of
Permitted Junior Securities) on account of principal of or premium, if any, or
interest on the Notes, including payment of the Redemption Price and the Change
of Control Purchase Price on the Notes, may be made, and the Notes may not be
converted into Common Stock, if a Non-payment Event of Default shall have
occurred and be continuing, for the period (a "Payment Blockage Period")
commencing on receipt of notice of such event of default by the Trustee from
holders of at least a majority in principal amount of any Designated Senior
Indebtedness (or any trustee or other representative therefor) and ending on the
earlier of (i) the date such Non-payment Event of Default has been cured or
waived or has ceased to exist or any acceleration of such Designated Senior
Indebtedness has been rescinded or annulled or such Designated Senior
Indebtedness shall have been discharged and (ii) the date 176 days after such
receipt of notice. Any number of such notices may be given; provided, however,
that, during any 360-day period, the aggregate Payment Blockage Periods shall
not exceed 176 days and there shall be a period of at least 184 consecutive days
when no Payment Blockage Period is in effect. No default existing or continuing
when a Payment Blockage Period begins may be the basis for any subsequent
Payment Blockage Period unless such default has been cured for a period of at
least 90 consecutive days. In the event that, notwithstanding the restrictions
described in the preceding sentences, the Company makes any payment to the
Trustee or a holder of Notes prohibited by any such restriction, with such
Trustee or holder, as the case may be, knowing of such contravention before
receipt thereof, then such payment will be required to be paid over and
delivered forthwith to the Company to the extent necessary to pay in full all
such Senior Indebtedness (Section 1303).
    
 
   
     The subordination rights of holders of Senior Indebtedness will not be
prejudiced or impaired by any acts or failures to act by the Company or by any
such holder (Section 1308). The subordination of the Notes set forth above will
not prevent the occurrence of any Event of Default under the Indenture.
Furthermore, the subordination of the Notes as set forth above will not impair,
as between the Company, the holders of the Notes and creditors of the Company
other than holders of Senior Indebtedness, the obligations of the Company to
make payments on the Notes in accordance with their terms. In certain
circumstances, as set forth in the Indenture, the holders of Notes will be
subrogated to certain rights of the holders of Senior Indebtedness upon payment
in full of all Senior Indebtedness (Section 1302).
    
 
   
     By reason of such subordination, in the event of insolvency of the Company,
the holders of Senior Indebtedness (as well as other creditors of the Company
who are holders of indebtedness that is not subordinated to the Senior
Indebtedness) may recover more, ratably, than the holders of the Notes.
    
 
   
     The Notes will also be effectively subordinated to all liabilities,
including trade payables and capitalized lease obligations, if any, of the
Company's subsidiaries. Any right of the Company to receive the assets of any of
its subsidiaries upon their liquidation or reorganization (and the consequent
right of the holders of the
    
 
                                       30
   32
 
   
Notes to participate in those assets) will be subject to the prior payment of
claims of that subsidiary's creditors (including trade creditors), except to the
extent that the Company is itself a creditor of such subsidiary, in which case
the claims of the Company would still be subject to the prior payment of claims
secured by security interests in the assets of such subsidiary and any other
indebtedness of such subsidiary senior to that held by the Company.
    
 
   
     Immediately following the sale of the Notes offered hereby and application
of the proceeds therefrom, the Company estimates that the sum of its Senior
Indebtedness and the indebtedness of its subsidiaries will total approximately
$50 million. There are no restrictions in the Indenture on the creation of
Senior Indebtedness (or any other indebtedness). The agreements under which
Senior Indebtedness may be outstanding in the future could contain provisions
which may require repayment of such respective Senior Indebtedness prior to
repayment of the Notes upon, among other things, a Change of Control. If the
Company is unable to obtain the requisite consents under its Senior Indebtedness
to enable it to repurchase the Notes or is unable to repay all Senior
Indebtedness, there would be both an Event of Default under the Notes and an
event of default under such Senior Indebtedness, as a result of which events the
Company would be prohibited by the subordination terms of the Indenture from
repurchasing Notes or making other payments in respect thereof. Furthermore, the
exercise by the holders of their right to require the Company to repurchase the
Notes could cause a default under the Designated Senior Indebtedness of the
Company, even if the Change of Control itself does not, due to the financial
effect of such repurchase on the Company. As a result, the repurchase of the
Notes could be blocked pursuant to the subordination terms of the Indenture.
Finally, the Company's ability to pay cash to the holders of Notes upon a
repurchase may be limited by the Company's then existing financial resources.
Failure of the Company to pay the Change of Control Purchase Price will create
an Event of Default with respect to the Notes, whether or not such repurchase is
permitted by the subordination terms of the Indenture. See " -- Repurchase of
Notes at the Option of the Holder Upon a Change of Control."
    
 
     "Bank Credit Facility" means the Company's existing bank credit facility
and any renewals, amendments, extensions, supplements, modifications,
refinancings or replacements thereof (Section 101).
 
     "Designated Senior Indebtedness" means (i) all Senior Indebtedness under
the Bank Credit Facility if the sum of the amounts outstanding under the Bank
Credit Facility and the amounts available for borrowing thereunder is equal to

outstanding principal amount equal to or greater than $25,000,000 (provided,
however, that the agreements, indentures or other instruments evidencing any
Senior Indebtedness referred to in this clause (ii) specifically state that such
Senior Indebtedness shall be classified as "Designated Senior Indebtedness" for
purposes of the Indenture) (Section 101).
 
     "Indebtedness" of any Person means, without duplication, (i) every
obligation of such Person for money borrowed; (ii) every obligation of such
Person evidenced by bonds, debentures, notes or similar instruments, including
obligations incurred in connection with the acquisition of property, assets or
businesses; (iii) every obligation of such Person under conditional sale or
other title retention agreements relating to assets or property purchased by
such Person or issued or assumed as the deferred purchase price of property,
assets or services (but excluding trade accounts payable or accrued liabilities
arising in the ordinary course of business that are not overdue by more than 90
days or are being contested by such Person in good faith); (iv) every Capital
Lease Obligation of such Person; (v) every obligation of such Person with
respect to any Sale and Leaseback Transaction to which such Person is a party;

of such Person; (viii) every obligation of such Person with respect to
performance, surety or similar bonds; (ix) every obligation of such Person under
interest rate, commodity or foreign currency swap, cap, hedge, exchange or
similar agreements; (x) every obligation of the type referred to in clauses (i)
through (ix) and clause (xi) of another Person the payment of which such Person
has Guaranteed or is otherwise responsible for or liable for, directly or
indirectly, as obligor, Guarantor or otherwise; and (xi) every amendment,
modification, renewal and extension of an obligation of the type referred to in
clauses (i) through (x) (Section 101).
 
                                       31
   33
 
     "Non-payment Event of Default" means any event (other than a Payment Event
of Default) the occurrence of which entitles any one or more persons to
accelerate the maturity of any Designated Senior Indebtedness (Section 101).
 
     "Payment Event of Default" means any default in the payment of principal of
or premium, if any, or interest on any Designated Senior Indebtedness when due
(whether at maturity, upon acceleration or otherwise) (Section 101).
 
   
     "Permitted Junior Securities" means subordinated debt securities of the
Company (or any successor obligor with respect to the Senior Indebtedness)
provided for by a plan of reorganization or readjustment that are subordinated
in right of payment to all Senior Indebtedness that may be outstanding to
substantially the same extent as, or to a greater extent than, the Notes are
subordinated as provided in the Indenture (Section 101).
    
 
   
     "Senior Indebtedness" means all obligations of the Company for Indebtedness
(other than Indebtedness described in clause (vii) of the definition of
Indebtedness), whether now existing or hereafter incurred or assumed; provided
that, Senior Indebtedness shall not include (A) any obligation owed to a
Subsidiary or an Affiliate or Related Person of the Company, (B) any obligation
that by its terms is not superior in right of payment to the Notes, (C) any
obligation in respect of the Company's 8% Convertible Subordinated Debentures
and 6% Convertible Subordinated Debentures, if and when issued, for which the
Company's existing preferred stock is exchangeable (the Notes not being senior
in right of payment to such debentures) or (D) any obligation constituting a
trade account payable (Section 101).
    
 
REDEMPTION
 
   
     The Notes will be redeemable, at the Company's option, as a whole or from
time to time in part, at any time on or after March 31, 1997, upon not less than
20 nor more than 60 days notice mailed to the registered holders thereof, at the
redemption prices (expressed as a percentage of the principal amount thereof)
set forth below if redeemed during the 12-month period beginning March 31 of the
years indicated:
    
 
   


                YEAR                                           REDEMPTION PRICE
                ----                                           ----------------
                                                            
                1997.........................................           %
                1998.........................................           %
                1999.........................................           %
                2000.........................................           %

    
 
together, in each case, with accrued interest to the Redemption Date (subject to
the right of holders of record on the relevant record date to receive interest
due on an Interest Payment Date that is on or prior to the Redemption Date)
(Sections 203, 1101, and 1107).
 
   
     If less than all the Notes are to be redeemed, the Notes to be redeemed
shall be selected by the Trustee in such manner as the Trustee shall deem
appropriate and fair (Section 1104).
    
 
   
     The Company's existing bank credit facility prohibits the Company from
redeeming any Notes unless (i) such redemption is permitted under the restricted
payment covenant contained in such bank credit facility and (ii) at the time of
such redemption and after giving effect thereto, no default shall have occurred
under such bank credit facility.
    
   
REPURCHASE OF NOTES AT THE OPTION OF THE HOLDER UPON A CHANGE OF CONTROL
    
   
     In the event of any Change of Control (as defined below) with respect to
the Company which constitutes a Repurchase Event (as defined below), each holder
of Notes will have the right, at such holder's option, subject to the terms and
conditions of the Indenture, to require the Company to repurchase all or any
part (provided that the principal amount must be $1,000 or an integral multiple
thereof) of the holder's Notes on the date (the "Change of Control Purchase
Date") that is 60 days after the date the Company's Change of Control Notice (as
defined below) is mailed (or such later date as is required by law), at a cash
price equal to 100% of the principal amount plus accrued interest to the Change
of Control Purchase Date (the "Change of
    
                                       32
   34
 
   
Control Purchase Price"). The Change of Control Purchase Price may be less than
the fair market value of the Notes on the Change of Control Purchase Date.
Promptly, but in any event within 29 days following any Change of Control, the
Company is required, with respect to any Senior Indebtedness that would prohibit
the repurchase of Notes by the Company in the event of such Change of Control,
either to repay all such Senior Indebtedness in full or obtain the requisite
consents under such Senior Indebtedness to permit the repurchase of the Notes as
provided below. The Company first is required to comply with the covenants in
the preceding sentence before it is required to repurchase Notes pursuant to a
Change of Control. The foregoing will in no way limit the occurrence of an Event
of Default, including an Event of Default arising from a default under the
covenants of the second sentence of this paragraph (Section 1401 and 1402).
    
 
   
     Within 29 days after a Change of Control which constitutes a Repurchase
Event, the Company is obligated to mail to the Trustee and to all holders of
Notes at their addresses shown in the register of the Security Registrar (and to
beneficial owners as required by applicable law) a notice (the "Change of
Control Notice") regarding the Change of Control. The Change of Control Notice
will describe: (i) the events causing the Change of Control; (ii) the Change of
Control Purchase Price; (iii) the Change of Control Purchase Date; (iv)
information regarding the conversion rights of the Notes; and (v) the procedures
for withdrawing a Change of Control Purchase Notice. The Change of Control
Notice will also state whether or not the Company has satisfied its obligations
regarding Senior Indebtedness referred to in the preceding paragraph (Section
1401).
    
 
   
     To exercise the right to have Notes repurchased following a Change of
Control, a holder must deliver a Change of Control Purchase Notice to the Paying
Agent at its office maintained for such purpose, prior to the close of business
on the Change of Control Purchase Date. The Change of Control Purchase Notice
shall state: (i) the certificate numbers of the Notes to be delivered by the
holder thereof for purchase by the Company; (ii) the portion of the principal
amount of Notes to be repurchased, which portion must be $1,000 or an integral
multiple thereof; and (iii) that such Notes are to be repurchased by the Company
pursuant to the applicable provision of the Indenture (Section 1401). A holder
of record of Notes shall be entitled to deliver a Change of Control Purchase
Notice with respect to any or all Notes held by it; provided, however, that such
holder may be required to provide evidence satisfactory to the Company that,
with respect to each beneficial holder of the Notes to be delivered to the
Company, such beneficial holder is exercising the right to require the
repurchase of all of the Notes in which it has a beneficial interest.
    
 
   
     Any Change of Control Purchase Notice may be withdrawn by the holder by a
written notice of withdrawal delivered to the Paying Agent prior to the close of
business on the Change of Control Purchase Date. The notice of withdrawal shall
state the principal amount and the certificate numbers of the Notes as to which
the withdrawal notice relates and the principal amount, if any, which remains
subject to a Change of Control Purchase Notice (Sections 1401 and 1402).
    
 
   
     Payment of the Change of Control Purchase Price for Notes for which a
Change of Control Purchase Notice has been delivered and not withdrawn is
conditioned upon delivery of such Notes (together with necessary endorsements)
to the Paying Agent at its office maintained for such purpose, at any time
(whether prior to, on, or after the Change of Control Purchase Date) after the
delivery of such Change of Control Purchase Notice. Payment of the Change of
Control Purchase Price for such Notes will be made promptly following the later
of the Change of Control Purchase Date and the time of delivery of such Notes
(Sections 1401 and 1402).
    
 
   
     "Change of Control" shall occur when: (i) all or substantially all of the
Company's assets are sold as an entirety to any person or related group of
persons; (ii) there shall be consummated any consolidation or merger of the
Company (A) in which the Company is not the continuing or surviving corporation
(other than a consolidation or merger with a wholly-owned subsidiary of the
Company in which all shares of Common Stock outstanding immediately prior to the
effectiveness thereof are changed into or exchanged for the same consideration)
or (B) pursuant to which the Common Stock would be converted into cash,
securities or other property, in each case other than a consolidation or merger
of the Company in which the holders of the Common Stock immediately prior to the
consolidation or merger have, directly or indirectly, at least a majority of the
Common Stock of the continuing or surviving corporation immediately after such
consolida-
    
 
                                       33
   35
 
   
tion or merger; or (iii) any person or any persons acting together which would
constitute a "group" for purposes of Section 13(d) of the Exchange Act (other
than the Company, any Subsidiary, any employee stock purchase plan, stock option
plan or other stock incentive plan or program, retirement plan or automatic
dividend reinvestment plan or any substantially similar plan of the Company or
any Subsidiary or any person holding securities of the Company for or pursuant
to the terms of any such employee benefit plan), together with any affiliates
thereof, shall Beneficially Own, directly or indirectly, at least 50% of the
total Voting Stock of the Company (Section 1401). As noted above, one of the
events that constitutes a Change of Control is a sale of all or substantially
all of the assets of the Company as an entirety to any person or related group
of persons. The Indenture will be governed by New York law, and there is no
established quantitative definition under New York law of "substantially all" of
the assets of a corporation. This uncertainty may make it more difficult for a
holder of Notes to determine whether a Change of Control has occurred in the
event that the Company were to engage in a transaction in which it sold less
than all of its assets.
    
 
   
     A Change of Control as described above shall constitute a Repurchase Event
unless (i) the closing price per share of the Common Stock on the five
consecutive Trading Days selected by the Company out of the 10 consecutive
Trading Days ending immediately after the later of the Change of Control or the
public announcement of the Change of Control (in the case of a Change of Control
under clauses (i) or (ii) of the definition of Change of Control) or ending
immediately before the Change of Control (in the case of a Change of Control
under clause (iii) of the definition of Change of Control) is at least equal to
105% of the conversion price of the Notes in effect immediately preceding the
time of such Change of Control, or (ii) all of the consideration (excluding cash
payments for fractional shares) in the transaction giving rise to such Change of
Control to the holders of Common Stock consists of shares of common stock that
are, or immediately upon issuance will be, listed on a national securities
exchange or quoted in the Nasdaq National Market, and as a result of such
transaction the Notes become convertible solely into such Common Stock and
neither Moody's Investors Service, Inc. nor Standard & Poor's, principally as a
result of the Change of Control, has downgraded the rating on the Notes by one
or more gradations below the rating of the Notes on the original issuance date
thereof within 90 days after the date of the public announcement of the Change
of Control (which period shall be extended so long as the rating of the Notes is
under publicly announced consideration for possible downgrade by any of the
rating agencies), or (iii) the consideration in the transaction giving rise to
such Change of Control to the holders of Common Stock consists of cash,
securities that are, or immediately upon issuance will be, listed on a national
securities exchange or quoted in the Nasdaq National Market, or a combination of
cash and such securities, and the aggregate fair market value of such
consideration (which, in the case of such securities, shall be equal to the
average of the daily closing prices of such securities on the five consecutive
Trading Days selected by the Company out of the 10 consecutive Trading Days
following consummation of such transaction) is at least 105% of the conversion
price of the Notes in effect on the date immediately preceding the closing date
of such transaction (Section 1401).
    
 
   
     The Company, to the extent applicable and if required by law, will comply
with the provisions of Rule 13e-4 and any successor or similar provision under
the Exchange Act which may then be applicable and will file a Schedule 13E-4 or
any successor or similar schedule required thereunder in connection with any
offer by the Company to purchase Notes at the option of holders upon a Change of
Control (Section 1405). The Change of Control purchase feature of the Notes may
in certain circumstances make more difficult or discourage a takeover of the
Company and, thus, the removal of incumbent management. The Change of Control
purchase feature, however, is not the result of management's knowledge of any
specific effort to accumulate shares of Common Stock or to obtain control of the
Company by means of a merger, tender offer, solicitation or otherwise, or part
of any plan by management to adopt a series of anti-takeover provisions.
Instead, the Change of Control purchase feature is a result of negotiations
between the Company and the Underwriters. Management has no present intention to
engage in a transaction involving a Change of Control, although it is possible
that the Company would decide to do so in future. Subject to the limitation on
mergers discussed below, the Company could, in the future, enter into certain
transactions, including certain recapitalizations, sales of assets, or the
liquidation of the Company, that would not constitute a Change of Control under
the Indenture, but that would increase the amount of Senior Indebtedness (or any
other indebtedness) outstanding at such time or substantially reduce or
eliminate the Company's assets. There are
    
 
                                       34
   36
 
   
no restrictions in the Indenture on the creation of additional Senior
Indebtedness (or any other indebtedness), and, under certain circumstances, the
incurrence of significant amounts of additional indebtedness could have an
adverse effect on the Company's ability to service its indebtedness, including
the Notes. If a Change of Control were to occur, there can be no assurance that
the Company would have sufficient funds to pay the Change of Control Purchase
Price for all Notes tendered by the holders thereof.
    
 
   
     No Note may be purchased pursuant to the Change of Control provisions if
there has occurred and is continuing an Event of Default described under
" -- Events of Default" (Section 1402).
    
 
   
     The Company's existing bank credit facility prohibits the Company from
repurchasing any Notes unless (i) such repurchase is permitted under the
restricted payment covenant contained in such bank credit facility and (ii) at
the time of such repurchase and after giving effect thereto, no default shall
have occurred under such bank credit facility. In addition, the agreements under
which Senior Indebtedness may be outstanding in the future could contain
provisions which may require repayment of such respective Senior Indebtedness
prior to repayment of the Notes upon, among other things, a Change of Control.
If the Company is unable to obtain the requisite consents under its Senior
Indebtedness to enable it to repurchase the Notes or is unable to repay all
Senior Indebtedness, there would be both an Event of Default under the Notes and
an event of default under such Senior Indebtedness, as a result of which events
the Company could be prohibited by the subordination provisions of the Indenture
from repurchasing Notes or making other payments in respect thereof.
Furthermore, the exercise by the holders of their right to require the Company
to repurchase the Notes could cause a default under the Senior Indebtedness of
the Company, even if the Change of Control itself does not, due to the financial
effect of such repurchase on the Company. As a result, the repurchase of the
Notes could be blocked pursuant to the subordination terms of the Indenture.
Finally, the Company's ability to pay cash to the holders of Notes upon a
repurchase may be limited by the Company's then existing financial resources.
Failure of the Company to pay the Change of Control Purchase Price will be a
default under the Indenture and could result in an Event of Default with respect
to the Notes, whether or not such repurchase is permitted by the subordination
provisions. See "-- Events of Default."
    
 
LIMITATION ON MERGERS
 
   
     The Company may, without the consent of the holders of the Notes,
consolidate with or merge into any other entity or convey, transfer or lease its
properties and assets substantially as an entirety to any person, provided that:
(1) the entity formed by such consolidation or into which the Company is merged
or the person that acquires by conveyance or transfer, or which leases the
properties and assets of the Company substantially as an entirety, must be a
corporation, partnership or trust organized and existing under the laws of the
United States, any state thereof or the District of Columbia; (2) the successor
entity expressly assumes, by a supplemental indenture executed and delivered to
the Trustee, in form satisfactory to the Trustee, the due and punctual payment
of the principal of and premium, if any, and interest on all Notes and the
performance of every covenant of the Indenture on the part of the Company to be
performed or observed and provides for conversion rights in accordance with the
Indenture; and (3) immediately after giving effect to such transaction, no Event
of Default, and no event which, after notice or lapse of time, or both, would
become an Event of Default, shall have occurred and be continuing (Section 801).
Upon compliance with these provisions by a successor entity, the Company (except
in the case of a lease) would be relieved of its obligations under the Indenture
and the Notes (Section 802).
    
 
MODIFICATION AND WAIVER
 
   
     Modifications and amendments of the Indenture, with certain exceptions, may
be made by the Company and the Trustee, only with the consent of the holders of
not less than a majority in aggregate principal amount of the Notes at the time
outstanding, and holders of not less than a majority in aggregate principal
amount of the Notes at the time outstanding may waive compliance by the Company
with certain provisions of the Indenture; provided, however, that no such
modification, amendment or waiver may, without the consent of the holder of each
outstanding Note affected thereby, (i) change the Stated Maturity of the
principal of or the due date of any installment of interest on any Note, (ii)
reduce the principal amount of, or the rate of interest on, or any premium
payable upon redemption of, any Note, (iii) change the currency of payment of
principal
    
 
                                       35
   37
 
   
of, or premium, if any, or interest on, any Note, (iv) impair the right to
institute suit for the enforcement of any payment on or with respect to any Note
on or after the Stated Maturity, or the Redemption Date in case of the
redemption of any Note, (v) adversely affect the right of a holder to convert
Notes, (vi) modify the provisions of the Indenture with respect to the
subordination of the Notes in a manner adverse to the holders, (vii) reduce the
above-stated percentage of outstanding Notes necessary to modify or amend the
Indenture, or (viii) reduce the percentage in aggregate principal amount of
outstanding Notes necessary for waiver of compliance with certain provisions of
the Indenture or for waiver of certain defaults (Sections 902 and 1009).
    
 
   
     The holders of a majority in aggregate principal amount of the outstanding
Notes may waive any past default under the Indenture except, among other things,
a default in the payment of principal of or premium, if any, or interest on any
Note, including the Redemption Price, or a default with respect to right of
holders to convert the Notes (Section 513).
    
 
EVENTS OF DEFAULT
 
   
     The following will be Events of Default under the Indenture: (i) failure to
pay principal of, premium, if any, or Redemption Price when due on any Note,
whether or not such payment is prohibited by the subordination provisions of the
indenture; (ii) failure to pay any interest on any Note 30 days after payment is
due, whether or not such payment is prohibited by the subordination provisions
of the Indenture; (iii) failure to perform any other covenant of the Company in
the Indenture, and such failure continues for 60 days after written notice by
the Trustee or the holders of at least 25% in principal amount of the
outstanding Notes as provided in the Indenture; (iv) default under any mortgage,
indenture or instrument under which there may be issued, or by which there may
be secured or evidenced, any indebtedness of the Company in excess of an
aggregate of $10,000,000 either for borrowed money or representing any Senior
Indebtedness (other than indebtedness which is nonrecourse to the Company beyond
the property securing such indebtedness) resulting in the acceleration of such
indebtedness prior to its express maturity (provided however, that the Event of
Default under this clause (iv) shall be automatically deemed remedied and cured
if the default under such accelerated indebtedness is remedied or cured by the
Company or waived by the holder of such indebtedness); and (v) certain events of
bankruptcy, insolvency or reorganization of the Company (Section 501).
    
 
   
     Notwithstanding the 60-day period and notice requirement referred to in
clause (iii) above, with respect to a default under the Change of Control
provisions, (1) the 60-day period referred to in clause (iii) above will be
deemed to have begun as of the date the Change of Control Notice is required to
be sent in the event the Change of Control Notice indicates (or would, if sent,
indicate) that the Company has not complied with its obligation to either repay
or obtain the requisite consents under any Senior Indebtedness that would
prohibit the repurchase of the Notes, and either (a) the holders duly elect to
have at least 25% in principal amount of outstanding Notes repurchased or (b)
the holders of at least 25% in principal amount of the outstanding Notes or the
Trustee thereafter gives the Notice of Default to the Company and, if
applicable, the Trustee, and (2) if the breach or default is a result of a
default in the payment when due of the Change of Control Purchase Price on the
Change of Control Purchase Date, such default shall arise on the Change of
Control Purchase Date, provided that either the holders of at least 25% in
principal amount of the Notes or the Trustee thereafter gives the Notice of
Default to the Company and, if applicable, the Trustee (Section 501).
    
 
   
     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, unless such holders
shall have offered to the Trustee reasonable indemnity (Sections 601 and 603).
Subject to such provisions for the indemnification of the Trustee, the holders
of 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 (Section 512).
    
 
   
     If an Event of Default shall occur and be continuing, other than an event
of bankruptcy, insolvency or reorganization of the Company, either the Trustee
or the holders of at least 25% of the principal amount of the outstanding Notes
may accelerate the maturity of all Notes upon the earlier of (1) five business
days after notice of such acceleration is received by the Company (and the
Trustee if given by holders) and (2) a
    
 
                                       36
   38
 
   
payment default under or acceleration of any Senior Indebtedness or such other
earlier time as the final maturity date for such Senior Indebtedness occurs. If
an Event of Default shall occur and be continuing which is an event of
bankruptcy, insolvency or reorganization of the Company, the maturity of all
Notes shall immediately accelerate without any act on the part of the Trustee or
any holder. If an Event of Default shall occur and be continuing as a result of
an acceleration of indebtedness of the type described in clause (iv) above, a
declaration of acceleration under the Indenture shall automatically be annulled
if the holders of the accelerated indebtedness described in clause (iv) above
have rescinded their declaration of acceleration within 90 days thereof and no
other Event of Default has occurred during such 90-day period which has not been
cured or waived. After acceleration upon the Event of Default, but before a
judgment or decree based on acceleration, the holders of a majority in aggregate
principal amount of outstanding Notes may, under certain circumstances, rescind
and annul such acceleration if, among other things, all Events of Default, other
than the non-payment of accelerated principal, have been cured or waived as
provided in the Indenture (Section 502). For information as to waiver of
defaults, see " -- Modification and Waiver."
    
 
   
     No holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless such holder shall
have previously given to the Trustee written notice of a continuing Event of
Default, the holders of at least 25% in aggregate principal amount of the
outstanding Notes shall have made written request, and offered reasonable
indemnity, to the Trustee to institute such proceeding as trustee, the Trustee
shall not have received from the holders of a majority in aggregate principal
amount of the outstanding Notes a direction inconsistent with such request and
the Trustee shall have failed to institute such proceeding within 60 days after
such notice (Section 507). However, such limitations do not apply to a suit
instituted by a holder of a Note for the enforcement of payment of the principal
of or premium, if any, or interest on such Note or the Redemption Price on or
after the respective due dates expressed in such Note or of the right to convert
such Note in accordance with the Indenture (Section 508).
    
 
     The Company will be required annually to furnish to the Trustee a statement
as to any default in its performance of certain of its obligations under the
Indenture (Section 1004).
 
DISCHARGE OF INDENTURE; DEFEASANCE
   
     The Company may terminate substantially all obligations under the Indenture
at any time by delivering all outstanding Notes to the Trustee for cancellation
and paying any other sums payable under the Indenture (Article IV).
    
      The Indenture also provides that the Company may elect:
   
          (a) to defease and be discharged from any and all obligations with
     respect to the Notes and that the provisions of the Indenture (including
     the provisions described under " -- Subordination of Notes") will no longer
     be in effect with respect to the Notes (except for the obligations to
     register the transfer or exchange of the Notes, to replace temporary or
     mutilated, destroyed, lost or stolen Notes, to maintain an office or agency
     in respect of Notes and to hold monies for payment in trust)
     ("Defeasance"); or
    
 
   
          (b) to be released from its obligations with respect to the Notes
     under certain restrictive covenants of the Indenture, and that the event of
     the type described under the clause (iv) under " -- Events of Default" will
     not be deemed to be an Event of Default under the indenture and that the
     provisions described under " -- Subordination of Notes" will not apply
     ("Covenant Defeasance").
    
 
   
     Such Defeasance or Covenant Defeasance will take effect only upon the
deposit with the Trustee (or other qualifying trustee), in trust for such
purpose, of money or U.S. Government Obligations that, through the payment of
principal and interest in accordance with their terms, will provide money, in an
amount sufficient to pay the principal of and premium, if any, and interest on
the Notes on the dates such payments are due, which may include one or more
Redemption Dates designated by the Company (other than in connection with a
Change of Control occurring after such Defeasance or Covenant Defeasance), in
accordance with the terms of the Notes (Article XV).
    
 
   
     Such a trust may be established with respect to the Notes only if, among
other things: (i) such Defeasance or Covenant Defeasance will not result
(whether immediately or with notice or lapse of time or
    
                                        37
   39
 
   
both) in an Event of Default under the Indenture; (ii) such deposit will not be
prohibited by the provisions of any agreement or instrument to which the Company
is a party or is bound; (iii) such deposit will not cause the Trustee to have
any conflicting interest with respect to other securities of the Company; (iv)
the Company has delivered to the Trustee an Opinion of Counsel to the effect
that the holders of the Notes will not recognize income, gain or loss for
federal income tax purpose as a result of such Defeasance or Covenant Defeasance
and will be subject to federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such Defeasance or
Covenant Defeasance had not occurred; and (v) the Company has delivered an
Officers' Certificate and an Opinion of Counsel, each to the effect that all
conditions precedent relating to such Defeasance or Covenant Defeasance have
been satisfied. Such Opinion of Counsel, in the case of Defeasance, must refer
to and be based upon a ruling of the Internal Revenue Service or a change in
applicable federal income tax law occurring after the issue date (Article XV).
    
 
   
     If the Company omits to comply with its remaining obligations under the
Indenture after Covenant Defeasance in respect of the Notes issued thereunder
and the Notes are declared due and payable because of the occurrence of an Event
of Default, the amount of money or U.S. Government Obligations on deposit with
the Trustee may be insufficient to pay amounts due on the Notes at the time any
acceleration of the maturity thereof resulting from such Event of Default.
However, the Company will remain liable in respect of such payments (Article
XV).
    
 
GOVERNING LAW
 
   
     The Indenture and the Notes will be governed by and construed in accordance
with the laws of the State of New York.
    
 
THE TRUSTEE
 
   
     Texas Commerce Bank National Association is the Trustee under the
Indenture. In the ordinary course of business the Company maintains other
commercial relationships with the Trustee and its affiliates. If the Trustee
shall acquire any conflicting interest (as defined in Section 301(b) of the
Trust Indenture Act) after a default under the Indenture, the Trustee either
shall eliminate such conflicting interest or resign as Trustee.
    
 
                          DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL STOCK
 
     The Company's authorized capital stock consists of 75,000,000 shares of
common stock, par value $.01 per share (the "Common Stock"), of which 23,259,658
were issued and outstanding at December 31, 1993, and 10,000,000 shares of
preferred stock, par value $.01 per share (the "Preferred Stock"), of which
2,221,005 were issued and outstanding as of December 31, 1993.
 
COMMON STOCK
 
     All shares of Common Stock have equal rights to participate in dividends
and, in the event of liquidation, assets available for distribution to
stockholders, subject to any preference established with respect to Preferred
Stock. Each holder of Common Stock is entitled to one vote for each share held
on all matters submitted to a vote of stockholders, and voting rights for the
election of directors are noncumulative. Shares of Common Stock carry no
conversion, preemptive or subscription rights, and are not subject to
redemption. All outstanding shares of Common Stock are, and any shares of Common
Stock issued upon conversion of convertible securities will be, validly issued,
fully paid and nonassessable. The Company pays dividends on Common Stock when,
as and if declared by the Board of Directors. Dividends may be declared in the
discretion of the Board of Directors from funds legally available therefor,
subject to restrictions under agreements related to Company indebtedness.
 
     The transfer agent for the Common Stock is Society National Bank, 3200
Renaissance Tower, 1201 Elm Street, Dallas, Texas 75270.
 
                                       38
   40
 
PREFERRED STOCK
 
     The Preferred Stock is issuable in one or more series or classes, any or
all of which may have such voting powers, full or limited, or no voting powers,
and such designations, preferences and related, participating, optional or other
special rights and qualifications, limitations or restrictions thereof, as are
set forth in the Company's Certificate of Incorporation, as amended, or in the
resolution or resolutions providing for the issue of such stock adopted by the
Board, which is expressly authorized to set such terms for any such issue.
 
     In November 1991, the Company issued 1,200,000 shares of $4.00 Exchangeable
Convertible Preferred Stock, of which 1,186,005 shares were outstanding on
December 31, 1993. Holders of such Preferred Stock are entitled to receive,
when, as and if declared by the Board of Directors out of funds legally
available therefor, cash dividends at an annual rate of $4.00 per share, payable
quarterly in arrears. Upon liquidation, such holders are entitled to receive a
preference of $50.00 per share, plus accrued and unpaid dividends to the payment
date. Each share of such Preferred Stock is convertible into 5.51 shares of
Common Stock at any time prior to redemption (subject to adjustment), equivalent
to a conversion price of $9.07 for each share of Common Stock. The Company has
the right to exchange the shares of such Preferred Stock for the Company's 8%
Convertible Subordinated Debentures due 2006 on any dividend payment date and,
subject to certain restrictions, the right to redeem such Preferred Stock
beginning January 1, 1995.
 
     In April 1993, the Company issued 1,035,000 shares (represented by
4,140,000 depositary shares) of $6.00 Exchangeable Convertible Preferred Stock,
all of which were outstanding on December 31, 1993. Holders of such Preferred
Stock are entitled to receive, when, as and if declared by the Board of
Directors out of funds legally available therefor, cash dividends at an annual
rate of $6.00 per share ($1.50 per depositary share), payable quarterly in
arrears. Upon liquidation, such holders are entitled to receive a preference of
$100.00 per share ($25.00 per depositary share), plus accrued and unpaid
dividends to the payment date. Each share of such Preferred Stock is convertible
into 4.762 shares of Common Stock at any time prior to redemption (subject to
adjustment), equivalent to a conversion price of $21.00 for each share of Common
Stock. The Company has the right to exchange the shares of such Preferred Stock
for the Company's 6% Convertible Subordinated Debentures due 2008 on any
dividend date payment on or after March 31, 1994 and the right to redeem such
Preferred Stock beginning March 31, 1996.
 
     The existing series of Preferred Stock rank prior to the Common Stock, and
on a parity with each other, as to dividends and upon liquidation, dissolution
or winding up.
 
FACTORS AFFECTING ACQUISITIONS OF CONTROL
 
     The Company's Certificate of Incorporation, as amended, provides that the
Board of Directors, in its discretion, may establish one or more class or series
of Preferred Stock having such number of shares, designations, relative voting
rights, dividend rates, liquidation and other rights, preferences and
limitations as may be fixed by the Board of Directors without any further
stockholder approval. Such rights, preferences, privileges and limitations could
have the effect of impeding or discouraging the acquisition of control of the
Company.
 
     The Company is a Delaware corporation and is subject to Section 203 of the
Delaware General Corporation Law (the "DGCL"). In general, Section 203 prevents
an "interested stockholder" (defined generally as a person owning 15% or more of
a corporation's outstanding voting stock) from engaging in a "business
combination" (as defined) with a Delaware corporation for three years following
the date such person became an interested stockholder unless (i) before such
person became an interested stockholder, the board of directors of the
corporation approved the transaction in which the interested stockholder became
an interested stockholder or approved the business combination; (ii) upon
consummation of the transaction that resulted in the interested stockholder's
becoming an interested stockholder, the interested stockholder owned at least
85% of the voting stock of the corporation outstanding at the time the
transaction commenced (excluding stock held by directors who are also officers
of the corporation and by employee stock plans that do not provide employees
with the right to determine confidentially whether shares held subject to the
plan will be tendered in a tender or exchange offer); or (iii) following the
transaction in which such person became an interested stockholder, the business
combination is approved by the board of directors of the corporation and
 
                                       39

authorized at a meeting of stockholders by the affirmative vote of the holders
of two-thirds of the outstanding voting stock of the corporation not owned by
the interested stockholder. Under Section 203, the restrictions described above
also do not apply to certain business combinations proposed by an interested
stockholder following the announcement or notification of one of certain
extraordinary transactions involving the corporation and a person who had not
been an interested stockholder during the previous three years or who became an
interested stockholder with the approval of a majority of the corporation's
directors, if such extraordinary transaction is approved or not opposed by a
majority of the directors who were directors prior to any person's becoming an
interested stockholder during the previous three years or who were recommended
for election or elected to succeed such directors by a majority of such
directors.
 
DIRECTORS' LIABILITY
 
     The Company's Certificate of Incorporation, as amended, also provides for
the elimination of directors' liability for monetary damages for a breach of
certain fiduciary duties and for the indemnification of directors, officers,
employees or agents as permitted by the DGCL. These provisions cannot be amended
without the affirmative vote of the holders of at least a majority in interest
of the outstanding shares entitled to vote.
 
     The Company has entered into indemnification agreements with all directors
and executive officers and may, in the future, enter into such agreements with
employees and agents. Such indemnification agreements provide generally that
such persons will be indemnified, to the extent permitted by applicable law, for
expenses (including attorneys' fees), judgments, penalties, fines and amounts
paid in settlement actually and reasonably incurred by such persons in
connection with any proceeding (including, to the extent permitted by law, any
derivative action) to which such persons are, or are threatened to be made, a
party by reason of their status in such positions. Such indemnification
agreements do not change the basic legal standards for indemnity under
applicable law or as set forth in the Certificate of Incorporation.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Registrant is incorporated in Delaware. Under Section 145 of the DGCL,
a Delaware corporation has the power, under specified circumstances, to
indemnify its directors, officers, employees and agents in connection with
actions, suits or proceedings brought against them by a third party or in the
right of the corporation, by reason of the fact that they were or are such
directors, officers, employees or agents, against expenses and liabilities
incurred in any such action, suit or proceeding so long as they acted in good
faith and in a manner that they reasonably believed to be in, or not opposed to,
the best interests of such corporation, and with respect to any criminal action,
that they had no reasonable cause to believe their conduct was unlawful. With
respect to suits by or in the right of such corporation, however,
indemnification is generally limited to attorneys' fees and other expenses and
is not available if such person is adjudged to be liable to such corporation
unless the court determines that indemnification is appropriate. A Delaware
corporation also has the power to purchase and maintain insurance for such
persons. Article Ninth of the Certificate of Incorporation of the Registrant
provides for mandatory indemnification of directors and officers to the fullest
extent permitted by Section 145 of the DGCL. Reference is made to the
Certificate of Incorporation of the Registrant.
 
     Reference is also made to the indemnification provisions of Section 7 of
the Underwriting Agreement, the form of which has been filed as Exhibit 1.1
hereto, under which the Underwriters have agreed to indemnify the Registrant,
its directors and officers and certain other persons against liabilities,
including liabilities under the Securities Act of 1933, with respect to
information furnished in writing to the Registrant for use in this Registration
Statement.
 
     The Registrant has entered into indemnification agreements with each of its
officers and directors and may in the future enter into such indemnification
agreements with its directors, officers, employees and agents. Such
indemnification agreements are intended to provide a contractual right to
indemnification, to the extent permitted by law, for costs, expenses (including
attorneys' fees and disbursements), judgments, penalties, fines and amounts paid
in settlement actually and reasonably incurred by the person to be indemnified
in connection with any proceeding (including, to the extent permitted by law,
any derivative action) to which they are, or are
 
                                      II-1
   47
 
threatened to be made, a party by reason of their status or decisions or actions
in such positions. Such indemnification agreements do not change the basic legal
standards for indemnification set forth in DGCL or the Certificate of
Incorporation of the Registrant. Such provisions are intended to be in
furtherance, and not in limitation of, the general right to indemnification
provided in the certificate of incorporation and Bylaws of the Registrant.
 
     Section 102(b)(7) of the DGCL provides that a certificate of incorporation
may contain a provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director provided that such provision may not eliminate
or limit the liability of a director (i) for any breach of the director's duty
of loyalty to the corporation or its stockholders, (ii) for acts or omissions
not in good faith or which involve intentional misconduct or a knowing violation
of law, (iii) under Section 174 (relating to liability for unauthorized
acquisitions or redemptions of, or dividends on, capital stock) of the DGCL or
(iv) for any transaction from which the director derived an improper personal
benefit. Article Tenth of the Registrant's Certificate of Incorporation contains
such a provision.
 
     The above discussion of the Registrant's Certificate of Incorporation and
Sections 102(b)(7) and 145 of the DGCL is not intended to be exhaustive and is
qualified in its entirety by such Certificate of Incorporation and statutes.

ITEM 17. UNDERTAKINGS.
 
     (a) The undersigned Registrant hereby undertakes that:
 
          (1) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this Registration Statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or 497(h) under the Securities Act shall be deemed to be part of this
     Registration Statement as of the time it was declared effective.
 
          (2) For the purpose of determining any liability under the Securities
     Act of 1933, each posteffective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.
 
     (b) The undersigned Registrant hereby further undertakes that, for purposes
of determining any liability under the Securities Act of 1933, each filing of
the Registrant's annual report pursuant to Section 13(a) or 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
Registration Statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
 
     (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the SEC such indemnification
is against public policy as expressed in the Act and is, therefore,
unenforceable. In the event that claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling persons of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

duly authorized, in the City of Fort Worth, State of Texas, on April 19, 1994.
