                                     PART I
 
ITEM 1. BUSINESS.
 
     Pogo Producing Company (the "Company"), incorporated in 1970, is engaged in
oil and gas exploration, development and production activities on its properties
located offshore in the Gulf of Mexico and onshore in the United States. The
Company is also engaged in exploration of its license concession in the Gulf of
Thailand, and has proposed to its joint venture partners a development program
in connection with its oil and gas discoveries on that concession. The Company
has interests in 73 lease blocks offshore Louisiana and Texas, approximately
125,000 gross acres onshore in the United States and approximately 2,635,000
gross acres offshore in the Kingdom of Thailand.
 
DOMESTIC OFFSHORE OPERATIONS
 
     Historically, the Company's interests have been concentrated in the Gulf of
Mexico, where approximately 81% of the Company's domestic proved reserves and
63% of its total proved reserves are now located. During 1994, approximately 82%
of the Company's natural gas equivalent production was from its domestic
offshore properties, contributing approximately 82% of consolidated oil and gas
revenues. Five offshore producing areas, Eugene Island, Main Pass, South Marsh
Island, South Pass and East Cameron, account for approximately 50% of the
Company's net proved natural gas reserves and approximately 56% of the Company's
proved crude oil, condensate and natural gas liquids reserves. Eugene Island is
the Company's largest producing area with 1994 average net revenue production
(net to the Company's interest and net of royalty burdens) of approximately 81
million cubic feet ("MMcf") per day of natural gas and 5,300 barrels ("Bbls")
per day of oil, condensate and natural gas liquids. The table in Item 2 of this
Annual Report on Form 10-K for the year ended December 31, 1994 (this "Annual
Report") summarizes the Company's offshore leasehold interests, drilling
activity, and platforms set or announced as of December 31, 1994.
 
  Lease Acquisitions
 
     The Company has participated with other companies in bidding on and
acquiring interests in federal leases offshore in the Gulf of Mexico since
December 1970. As a result of such sales and subsequent activities, the Company
owns interests in 67 federal leases offshore Louisiana and Texas. Federal leases
generally have primary terms of five years, subject to extension by development
and production operations. The Company also owns interests in six leases in
state waters offshore Louisiana.
 
     As part of its strategy, the Company intends to continue an active lease
evaluation program in the Gulf of Mexico in order to identify exploration and
exploitation opportunities. During 1994, the Company was successful in acquiring
interests in three lease blocks, Vermilion 335, High Island A-451 and Galveston
Block A-215, through federal Outer Continental Shelf oil and gas lease sales.
The Department of the Interior has announced its intention to hold two lease
sales during 1995 covering federal acreage in the Central and Western portions
of the Gulf of Mexico; and it is anticipated that various states will also hold
sales covering offshore state acreage from time to time. As in the case of prior
sales, the extent to which the Company participates in future bidding will
depend on the availability of funds and its estimates of hydrocarbon deposits,
operating expenses and future revenues which reasonably may be expected from
available lease blocks. Such estimates typically take into account, among other
things, estimates of future hydrocarbon prices, federal regulations, and
taxation policies applicable to the petroleum industry.
 
     It is also the Company's objective to acquire certain producing properties
where additional low-risk drilling or improved production methods by the Company
can provide attractive rates of return. During 1994, the Company purchased
additional working interests in portions of eight federal lease blocks in the
South Pass, Mississippi Canyon, Main Pass and High Island areas of the Gulf of
Mexico. In addition, the Company participated in the drilling of two wells in
the South Marsh Island area which earned the Company working interests in two
lease blocks, South Marsh Island Blocks 141 and 161.
 
                                        1
<PAGE>   3
 
  Exploration and Development
 
     The scope of exploration and development programs relating to the Company's
offshore interests is affected by prices for oil and gas, and by federal, state
and local legislation, regulations and ordinances applicable to the petroleum
industry. The Company's domestic offshore capital and exploration expenditures
for 1994 were approximately $48,700,000 (excluding approximately $32,600,000 of
net property acquisitions), or 20% higher than the Company's domestic offshore
capital and exploration expenditures of approximately $40,600,000 for 1993 and
453% higher than the Company's domestic offshore capital and exploration
expenditures of approximately $8,800,000 (excluding approximately $7,950,000 of
net property acquisitions) for 1992. Development and production related projects
represented 93% of the Company's 1994 domestic offshore capital and exploration
expenditures. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."
 
     Leases acquired by the Company and other participants in its bidding groups
are customarily committed, on a block-by-block basis, to separate operating
agreements under which the appointed operator supervises exploration and
development operations for the account and at the expense of the group. These
agreements usually contain terms and conditions which have become relatively
standardized in the industry. Major decisions regarding development and
operations typically require the consent of at least a majority (in working
interest) of the participants. Because the Company generally has a meaningful
working interest position, the Company believes it can influence decisions
regarding development and operations on most of the leases in which it has a
working interest even though it may not be the operator of a particular lease.
The Company is currently the operator on all or a portion of 21 of the 73
offshore leases in which it has an interest.
 
     Platforms are installed on an offshore lease block when, in the judgment of
the lease interest owners, the necessary capital expenditures are justified. A
decision to install a platform generally is made after the drilling of one or
more exploratory wells with contracted drilling equipment. Platforms are used to
accommodate both development drilling and additional exploratory drilling. In
recent years, the gross cost of production platforms to the joint ventures in
which the Company has varying net interests has typically averaged approximately
$9,100,000 per platform. Platform costs vary and more expensive platforms could
be required in the future depending on, among other factors, the number of
slots, water depth, currents, and sea floor conditions. During 1994, the Company
completed the installation of an additional platform on Eugene Island Block 295,
installed three platforms in a new field on Ship Shoal Blocks 240/256, and
installed a platform on Main Pass Block 123. See "Properties -- Principal
Properties."
 
     In 1989, the Company entered into a limited partnership agreement as
general partner of Pogo Gulf Coast, Ltd., a Texas limited partnership ("Pogo
Gulf Coast"), in which the Company agreed to be responsible for investing as
much as $60,000,000 on behalf of Pogo Gulf Coast for acquisition and exploration
in state and federal waters in the Gulf of Mexico. As of December 31, 1994, Pogo
Gulf Coast had interests in 16 federal offshore leases, and had invested a total
of approximately $55,500,000 for exploration and development of the properties
owned since the partnership began. The Company owns 40% of any interest in
properties acquired by the limited partnership. Unless otherwise noted, the
statistical data reported in this Annual Report reflect only the Company's share
of Pogo Gulf Coast's holdings.
 
DOMESTIC ONSHORE OPERATIONS
 
     The Company has onshore division staffs in Houston and Midland, Texas. Its
onshore activities are concentrated in known oil and gas provinces, principally
the Permian Basin of southeastern New Mexico and West Texas and the onshore Gulf
Coast area. The Company's primary drilling objective in southeastern New Mexico
is the Brushy Canyon (Delaware) formation which produces oil from depths of
6,000 to 9,000 feet. Since the Company began exploring in the Brushy Canyon
(Delaware) formation in October 1989, it has participated in the drilling of 209
wells through December 31, 1994, including 58 wells in 1994. During the fourth
quarter of 1994, the Company's net revenue interest portion of daily liquid
hydrocarbon production in New Mexico averaged approximately 3,950 Bbls which
represented approximately 30% of the Company's total average daily production of
oil, condensate and liquid plant products during the fourth quarter of 1994.
 
                                        2
<PAGE>   4
 
     The Company generally conducts its onshore activities through joint
ventures and other interest-sharing arrangements with major and independent oil
companies. The Company operates many of its own onshore properties using
independent contractors.
 
     The Company's domestic onshore capital and exploration expenditures were
approximately $32,000,000 for 1994, or 7% higher than the Company's domestic
onshore capital and exploration expenditures of approximately $29,800,000 for
1993 and 81% higher than the Company's domestic onshore capital and exploration
expenditures of approximately $17,650,000 (excluding approximately $950,000 of
net property acquisitions) for 1992. Development and production related projects
represented 74% of the Company's 1994 domestic onshore capital and exploration
expenditures. As of December 31, 1994, the Company held leases on 79,768 net
acres onshore in the United States. Onshore reserves as of December 31, 1994,
accounted for approximately 19% of the Company's domestic proved reserves and
approximately 14% of its total proved reserves. During 1994, approximately 18%
of the Company's natural gas equivalent production was from its domestic onshore
properties, contributing approximately 18% of consolidated oil and gas revenues.
 
INTERNATIONAL OPERATIONS
 
     The Company has conducted international exploration activities since the
late 1970's in numerous oil and gas areas throughout the world. The Company
pursues a strategy of evaluating potentially high return prospects in areas of
the world with a stable political and financial climate such as certain European
and ASEAN ("Association of Southeast Asian Nations") countries. The Company's
international capital and exploration expenditures were approximately $6,350,000
for 1994, or 6% higher than the Company's international capital and exploration
expenditures of approximately $6,000,000 for 1993 and 144% higher than the
Company's international capital and exploration expenditures of approximately
$2,600,000 for 1992. Substantially all of the Company's international capital
and exploration expenditures for 1994 were related to the Company's license in
the Kingdom of Thailand. However, the Company continues to evaluate other
international opportunities that are consistent with the Company's international
exploration strategy.
 
     In August 1991, the Company, through its wholly owned subsidiary Thaipo
Limited, together with its joint venture partners, was awarded a license from
the Kingdom of Thailand to explore for and produce oil and gas on Block B8/32, a
2.6 million acre tract in the Gulf of Thailand. Following an initial evaluation
of the Thailand concession area, the Company and its joint venture partners have
drilled eight wells on a seismic structure on a portion of the concession named
Tantawan. In October 1992, the Tantawan No. 1 well was drilled. During 1993, the
Company and its joint venture partners shot, processed and evaluated
approximately 9,000 square kilometers of new 3-D seismic data over and around
the Tantawan No. 1 well. In late 1993, the Company drilled the Tantawan No. 2
and the Tantawan No. 3 wells on the Tantawan structure. In early 1994, an
additional two wells, the Tantawan No. 4 and the Tantawan No. 5 delineation
wells, were successfully drilled on the Tantawan area seismic structure. This
success was repeated in late 1994 with the drilling of three more delineation
wells on the Tantawan area seismic structure.
 
     In March 1995, the Company reached an agreement with its partners in the
concession under which the Company currently anticipates that its working
interest in the Tantawan portion of the concession will increase from
approximately 31.7% to approximately 46.3%, upon approval of appropriate
governmental authorities in Thailand. The Company will also assume the duties of
operator on the Tantawan portion of the concession, which covers approximately
76,000 acres of the Block B8/32 license concession. Development activities on
the Tantawan portion of the concession are currently expected to commence in the
first half of 1995. Contingent upon availability of transportation and other
factors, the development program could lead to commencement of initial
production from reservoirs located on the Tantawan structure within 18 to 24
months. See "-- Miscellaneous; Sales;" and "Management's Discussion and Analysis
of Financial Condition and Results of Operations."
 
     At December 31, 1994, the Company's Thailand concession accounted for
approximately 23% of the Company's total estimated net proved reserves of
natural gas and approximately 23% of its total estimated net proved reserves of
oil, condensate and natural gas liquids. If the anticipated increase in the
Company's working interest in the Tantawan portion of the concession had been
effective at that date, those percentages would have been approximately 30%. All
such proved reserves in Thailand are located on the Tantawan portion of the
concession and are currently classified as proved undeveloped.
 
                                        3
<PAGE>   5
 
     In addition to its continuing efforts on the Tantawan structure, the
Company and its joint venture partners have shot, processed and are currently
evaluating 10,500 square kilometers of new 3-D seismic data on a different
portion of Block B8/32. The Company and its partners currently plan to drill at
least four more wells on the non-Tantawan portion of the Thailand concession
during 1995. The Company's working interest in the non-Tantawan portion of the
concession, which is operated by one of its partners, remains at approximately
31.7%.
 
     Any production resulting from the concession will be subject to a royalty
ranging from 5% to 15% of oil and gas sales, plus certain fixed dollar amounts
payable at specified cumulative production levels. Revenue from production in
Thailand will also be subject to income taxes and other governmental charges. As
set forth in the August 1991 concession, the exploratory term of the concession
is for a period of up to six years; provided, however, that after the expiration
of four years, a portion of the acreage in Block B8/32 must be relinquished by
the Company and its joint venture partners and removed from the concession
license. The Company must identify and release this acreage no later than August
1, 1995. During the concession's exploratory period, the Company and its joint
venture partners have certain work commitments involving the drilling of
exploratory wells or the expenditure of certain sums of money on exploration
activities. The Company and its joint venture partners have satisfied all of
these obligations. Following the commencement of production, the initial
production period of the concession is 20 years, subject to extension. See also
"-- Miscellaneous; Sales."
 
MISCELLANEOUS
 
  Other Assets
 
     The Company and a subsidiary, Pogo Offshore Pipeline Co., own minority
interests in three pipelines through which offshore oil production is
transported ashore. In addition, the Company owns an approximately 21% interest
in a cryogenic gas processing plant near Erath, Louisiana, which entitles it to
process up to 189 MMcf of gas per day. Currently, the plant is not operating at
full capacity.
 
  Sales
 
     The marketing of offshore oil and gas production is subject to the
availability of pipelines and other transportation, processing and refining
facilities as well as the existence of adequate markets. As a result, even if
hydrocarbons are discovered in commercial quantities, a substantial period of
time may elapse before commercial production commences. If pipeline facilities
in an area are insufficient, the Company may have to await the construction or
expansion of pipeline capacity before production from that area can be marketed.
The Company's domestic offshore properties are generally located in areas where
a pipeline infrastructure is well developed and there is adequate availability
in such pipelines to handle the Company's current and projected future
production. The Company's concession in Thailand is traversed by a major natural
gas pipeline that comes within approximately 25 miles of the Tantawan structure.
This pipeline is currently running at or near capacity. However, construction of
a second, parallel natural gas pipeline owned by an entity controlled by the
government of the Kingdom of Thailand has recently commenced, with completion
expected to occur during 1996. The Company is currently negotiating
transportation and sale arrangements with the Petroleum Authority of Thailand
for oil and gas expected to be produced from the Tantawan structure.
 
     The marketing of onshore oil and gas production is also subject to the
availability of pipelines, crude oil hauling and other transportation,
processing and refining facilities as well as the existence of adequate markets.
Generally, the Company's onshore domestic oil and gas production is located in
areas where commercial production of economic discoveries can be rapidly
effectuated.
 
     Most of the Company's natural gas sales are currently made in the "spot
market" for no more than one month at a time at then currently available prices.
Prices on the spot market fluctuate with demand. Crude oil and condensate
production is also generally sold one month at a time at the currently available
prices. Other than any futures contracts referred to in "-- Miscellaneous;
Competition and Market Conditions," the Company has no existing contracts that
require the delivery of fixed quantities of oil or natural gas other than
 
                                        4
<PAGE>   6
 
on a best efforts basis. See also "Financial Statements and Supplementary
Data -- Note 4 to Notes to Consolidated Financial Statements and -- Unaudited
Supplementary Financial Data."
 
  Competition and Market Conditions
 
     The Company experiences competition from other oil and gas companies in all
phases of its operations, as well as competition from other energy related
industries. The Company's profitability and cash flow are highly dependent upon
the prices of oil and natural gas, which historically have been seasonal,
cyclical and volatile. In general, prices of oil and gas are dependent upon
numerous factors beyond the control of the Company, including various weather,
economic, political and regulatory conditions. In the past, when natural gas
prices in the United States were lower than they are currently, the Company at
times elected to curtail certain quantities of its production. For example, in
the fourth quarter of 1994, the Company curtailed a small portion of its daily
natural gas production. As of February 1, 1995, the Company was not curtailing
any of its natural gas production as a result of low natural gas prices. Should
natural gas prices fall in the future, the Company may again elect to curtail
certain quantities of its natural gas production. Any significant decline in oil
or gas prices could have a material adverse effect on the Company's operations
and financial condition and could, under certain circumstances, result in a
reduction in funds available under the Company's bank credit facility. Because
it is impossible to predict future oil and gas price movements with any
certainty, the Company from time to time enters into contracts on a portion of
its production to hedge against the volatility in oil and gas prices. Such
hedging transactions, historically, have not exceeded 50% of the Company's total
oil and gas production on an energy equivalent basis for any given period. While
intended to limit the negative effect of price declines, such transactions could
effectively limit the Company's participation in price increases for the covered
period, which increases could be significant. The Company has entered into a
crude oil swap agreement with another party in which it had swapped the floating
market price it receives from purchasers of its crude oil for a fixed price of
$17.08 per barrel on 1,000 Bbls per day of the Company's production for a period
ending April 30, 1995. In addition, as of January 1, 1995, the Company had
entered into futures contracts with various parties on a portion of its daily
natural gas production through September 30, 1995 (commencing with contracts
totaling approximately 37 MMcf per day in January and decreasing on a quarterly
basis to approximately 15 MMcf per day) at varying prices ranging from
approximately $1.92 to $1.83 per thousand cubic feet ("Mcf"). When the Company
does engage in such hedging activities, it may satisfy its obligations with its
own production or by the purchase (or sale) of third party production. The
Company may also cancel all delivery obligations by offsetting such obligations
with equivalent agreements, thereby effecting a purely cash transaction.
 
  Operating and Uninsured Risks
 
     The Company's operations are subject to risks inherent in the exploration
for and production of oil and natural gas, such as blowouts, cratering,
explosions, uncontrollable flows of oil, natural gas or well fluids, fires,
pollution and other environmental risks. Offshore oil and gas operations are
subject to the additional hazards of marine and helicopter operations, such as
capsizing, collision and adverse weather and sea conditions. These hazards could
result in substantial losses to the Company due to injury or loss of life,
severe damage to and destruction of property and equipment, pollution and other
environmental damage and suspension of operations. The Company carries insurance
which it believes is in accordance with customary industry practices, but is not
fully insured against all risks incident to its business.
 
     Drilling activities are subject to numerous risks, including the risk that
no commercially productive hydrocarbon reserves will be encountered. The cost of
drilling, completing and operating wells and of installing production facilities
and pipelines is often uncertain. The Company's drilling operations may be
curtailed, delayed or canceled as a result of numerous factors, including
weather conditions, compliance with governmental requirements and shortages or
delays in the delivery of equipment. The availability of a ready market for the
Company's natural gas production depends on a number of factors, including the
demand for and supply of natural gas, the proximity of natural gas reserves to
pipelines, the capacity of such pipelines and government regulations.

  Risks of Foreign Operations
 
     Ownership of property interests and production operations in Thailand and
other areas outside the United States are subject to the various risks inherent
in foreign operations. These risks include, among others, currency restrictions
and exchange rate fluctuations, loss of revenue, property and equipment as a
result of hazards such as expropriation, nationalization, war, insurrection and
other political risks, risks of increases in taxes and governmental royalties,
renegotiation of contracts with governmental entities, as well as changes in
laws and policies governing operations of foreign-based companies. The Company
seeks to manage these risks by concentrating its international exploration
efforts in areas where the Company believes that the existing government is
stable and favorably disposed towards United States exploration and production
companies. The Company believes that the Kingdom of Thailand currently presents
favorable conditions in which to conduct international operations.

(a) "Developed acreage" consists of lease acres spaced or assignable to
     production on which wells have been drilled or completed to a point that
     would permit production of commercial quantities of oil and natural gas.
 
(b) Approximately 16% of the Company's total offshore net undeveloped acreage is
     under leases that have terms expiring in 1995, if not held by production,
     and another approximately 29% of offshore net undeveloped acreage will
     expire in 1996 if not also held by production. Approximately 19% of onshore
     net undeveloped acreage is under leases that have terms expiring in 1995,
     if not held by production, and another approximately 15% of onshore net
     undeveloped acreage will expire in 1996 if not also held by production.

  Productive Wells and Drilling Activity
 
     The following table shows the Company's interest in productive oil and
natural gas wells as of December 31, 1994. Productive wells are producing wells
plus wells "capable of production" (e.g., natural gas wells waiting for pipeline
connections or necessary governmental certification to commence deliveries and
oil wells waiting to be connected to production facilities).

(a) One or more completions in the same bore hole are counted as one well. The
    data in the above table includes 30 gross (7.4 net) oil wells and 16 gross
    (5.7 net) natural gas wells with multiple completions.
 
     The following table shows the number of successful gross and net
exploratory and development wells in which the Company has participated and the
number of gross and net wells abandoned as dry holes during the periods
indicated. An onshore well is considered successful upon the installation of
permanent equipment for the production of hydrocarbons. Successful offshore
wells consist of exploratory or development wells that have been completed or
are "suspended" pending completion (which has been determined to be feasible and
economic) and exploratory test wells that were not intended to be completed and
that encountered commercially producible hydrocarbons. A well is considered a
dry hole upon reporting of permanent abandonment to the appropriate agency.

</TABLE>
 
     Natural gas liquids comprise approximately 13% of the Company's total
proved liquids reserves and approximately 17% of the Company's proved developed
liquids reserves. All hydrocarbon liquid reserves are expressed in standard 42
gallon Bbls. All gas volumes and gas sales are expressed in MMcf at the pressure
and temperature bases of the area where the gas reserves are located.
 
     Proved reserves of crude oil, condensate, natural gas, and natural gas
liquids are estimated quantities that geological and engineering data
demonstrate with reasonable certainty to be recoverable in the future from known
reservoirs under existing conditions. Reservoirs are considered proved if
economic producibility is supported by actual production or formation tests. In
certain instances, proved reserves are assigned on the basis of a combination of
core analysis and electrical and other type logs which indicate the reservoirs
are analogous to reservoirs in the same field which are producing or have
demonstrated the ability to produce on a formation test. The area of a reservoir
considered proved includes (i) that portion delineated by drilling and defined
by fluid contacts, if any, and (ii) the adjoining portions not yet drilled that
can be reasonably judged as economically productive on the basis of available
geological and engineering data. In the absence of data on fluid contacts, the
lowest known structural occurrence of hydrocarbons controls the lower proved
limit of the reservoir. Proved reserves are estimates of hydrocarbons to be
recovered from a given date forward. They may
 
                                        9
<PAGE>   11
 
be revised as hydrocarbons are produced and additional data becomes available.
Proved natural gas reserves are comprised of nonassociated, associated and
dissolved gas. An appropriate reduction in gas reserves has been made for the
expected removal of liquids, for lease and plant fuel and the exclusion of
non-hydrocarbon gases if they occur in significant quantities and are removed
prior to sale. Reserves that can be produced economically through the
application of established improved recovery techniques are included in the
proved classification when these qualifications are met: (i) successful testing
by a pilot project or the operation of an installed program in the reservoir
provides support for the engineering analysis on which the project or program
was based, and (ii) it is reasonably certain the project will proceed. Improved
recovery includes all methods for supplementing natural reservoir forces and
energy, or otherwise increasing ultimate recovery from a reservoir, including,
(a) pressure maintenance, (b) cycling, and (c) secondary recovery in its
original sense. Improved recovery also includes the enhanced recovery methods of
thermal, chemical flooding, and the use of miscible and immiscible displacement
fluids. Estimates of proved reserves do not include crude oil, condensate,
natural gas, or natural gas liquids being held in underground storage. Depending
on the status of development, these proved reserves are further subdivided into:
 
          (i) "developed reserves" which are those proved reserves reasonably
     expected to be recovered through existing wells with existing equipment and
     operating methods, including (a) "developed producing reserves" which are
     those proved developed reserves reasonably expected to be produced from
     existing completion intervals now open for production in existing wells,
     and (b) "developed non-producing reserves" which are those proved developed
     reserves which exist behind casing of existing wells which are reasonably
     expected to be produced through these wells in the predictable future where
     the cost of making such hydrocarbons available for production should be
     relatively small compared to the cost of new wells; and
 
          (ii) "undeveloped reserves" which are those proved reserves reasonably
     expected to be recovered from new wells on undrilled acreage, from existing
     wells where a relatively large expenditure is required and from acreage for
     which an application of fluid injection or other improved recovery
     technique is contemplated where the technique has been proved effective by
     actual tests in the area in the same reservoir. Reserves from undrilled
     acreage are limited to those drilling units offsetting productive units
     that are reasonably certain of production when drilled. Proved reserves for
     other undrilled units are included only where it can be demonstrated with
     reasonable certainty that there is continuity of production from the
     existing productive formation.
 
     The Company has interests in certain tracts which may have substantial
additional hydrocarbon quantities which cannot be classified as proved and are
not included herein. The Company has active exploratory and development drilling
programs which in all likelihood will result in the reclassification of
significant additional quantities to the proved category.
 
     In computing future revenues from gas reserves attributable to the
Company's interests, prices in effect at December 31, 1994 were used, including
current market prices, contract prices and fixed and determinable price
escalations where applicable. In accordance with Commission guidelines, the
future gas prices that were used make no allowances for seasonal variations in
gas prices which are likely to cause future yearly average gas prices to be
somewhat lower than December gas prices. For gas sold under contract, the
contract gas price including fixed and determinable escalations, exclusive of
inflation adjustments, was used until the contract expires and then was adjusted
to the current market price for the area and held at this adjusted price to
depletion of the reserves. In computing future revenues from liquids
attributable to the Company's interest, prices in effect at December 31, 1994
were used and these prices were held constant to depletion of the properties.
With respect to the Company's Thailand properties, production was assumed to
commence in 1997, at sales prices that were estimated by the Company based in
part on reported sales prices for production from other producers in the area.
 
     The estimates of future net revenue from the Company's domestic and
Thailand properties are based on existing law where the properties are located
and are calculated in accordance with Commission guidelines. Operating costs for
the leases and wells include only those costs directly applicable to the leases
or wells. When applicable, the operating costs include a portion of general and
administrative costs allocated directly to
 
                                       10
<PAGE>   12
 
the leases and wells under terms of operating agreements. Development costs are
based on authorization for expenditure for the proposed work or actual costs for
similar projects. The current operating and development costs were held constant
throughout the life of the properties. For properties located onshore, the
estimates of future net revenues and the present value thereof do not consider
the salvage value of the lease equipment or the abandonment cost of the lease
since both are relatively insignificant and tend to offset each other. The
estimated net cost of abandonment after salvage was considered for offshore
properties where such costs net of salvage are significant.
 
     No deduction was made for indirect costs such as general and administrative
and overhead expenses, loan repayments, interest expenses, and exploration and
development prepayments. The accumulated gas production imbalances have been
taken into account.
 
     Production data used to arrive at the estimates set forth above includes
estimated production for the last few months of 1994.
 
     The future production rates from reservoirs now on production may be more
or less than estimated because of, among other reasons, mechanical breakdowns
and changes in market demand or allowables set by regulatory bodies. Properties
which are not currently producing may start producing earlier or later than
anticipated in the estimates of future production rates.
 
     The future prices received by the Company for the sales of its production
may be higher or lower than the prices used in calculating the estimates of
future net revenues and the present value thereof as set forth herein, and the
operating costs and other costs relating to such production may also increase or
decrease from existing levels; however, such possible changes in prices and
costs were, in accordance with rules adopted by the Commission, omitted from
consideration in arriving at such estimates.
 
     There are numerous uncertainties in estimating the quantity of proved
reserves and in projecting the future rates of production and timing of
development expenditures. 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 of Ryder Scott, the Company's reserve engineers.
The accuracy of any reserve estimate is a function of the quality of available
data and of engineering and geological interpretation and judgment. Results of
drilling, testing and production subsequent to the date of the estimate may
justify revision of such estimate. Accordingly, reserve estimates are often
different from the quantities of oil and gas that are ultimately recovered.
 
     The Company is periodically required to file estimates of its oil and gas
reserve data with various governmental regulatory authorities and agencies,
including the Federal Energy Regulatory Commission ("FERC") and the Federal
Trade Commission. In addition, estimates are from time to time furnished to
governmental agencies in connection with specific matters pending before such
agencies. The basis for reporting reserves to these agencies, in some cases, is
not comparable to that furnished above because of the nature of the various
reports required. The major differences include differences in the time as of
which such estimates are made, differences in the definition of reserves,
requirements to report in some instances on a gross, net or total operator basis
and requirements to report in terms of smaller geographical units. No estimates
by the Company of its total proved net oil and gas reserves, however, were filed
with or included in reports to any federal authority or agency other than the
Commission during 1994.
 
GOVERNMENT REGULATION
 
     The Company's operations are affected from time to time in varying degrees
by political developments and federal and state laws and regulations. Rates of
production of oil and gas have for many years been subject to federal and state
conservation laws and regulations, and the petroleum industry has been subject
to federal and state tax laws dealing specifically with it.
 
  Federal Income Tax
 
     The Company's operations are significantly affected by certain provisions
of the federal income tax laws applicable to the petroleum industry. The
principal provisions affecting the Company are those that permit the
 
                                       11
<PAGE>   13
 
Company, subject to certain limitations, to deduct as incurred, rather than to
capitalize and amortize, its domestic "intangible drilling and development
costs" and to claim depletion on a portion of its domestic oil and gas
properties based on 15% of its oil and gas gross income from such properties (up
to an aggregate of 1,000 Bbls per day of domestic crude oil and/or equivalent
units of domestic natural gas) even though the Company has little or no basis in
such properties. Under certain circumstances, however, a portion of such
intangible drilling and development costs and the percentage depletion allowed
in excess of basis will be tax preference items that will be taken into account
in computing the Company's alternative minimum tax. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources."
 
  Environmental Matters
 
     Offshore oil and gas operations are subject to extensive federal regulation
and, with respect to federal leases, to interruption or termination by
governmental authorities on account of environmental and other considerations
including the Comprehensive Environmental Response, Compensation and Liability
Act ("CERCLA") also known as the "Superfund Law." Regulations of the Department
of the Interior currently impose absolute liability upon the lessee under a
federal lease for the costs of clean-up of pollution resulting from a lessee's
operations, and such lessee may also be subject to possible legal liability for
pollution damages. The Company maintains insurance against costs of clean-up
operations, but is not fully insured against all such risks. A serious incident
of pollution may, as it has in the past, also result in the Department of the
Interior requiring lessees under federal leases to suspend or cease operation in
the affected area.
 
     The Oil Pollution Act of 1990 (the "OPA") and regulations thereunder impose
a variety of regulations on "responsible parties" (which include owners and
operators of offshore facilities) related to the prevention of oil spills and
liability for damages resulting from such spills in United States waters. In
addition it imposes ongoing requirements on responsible parties, including proof
of financial responsibility to cover at least some costs in a potential spill.
On August 25, 1993, the Mineral Management Service (the "MMS") published an
advance notice of its intention to adopt a rule under OPA that would require
owners and operators of offshore oil and gas facilities to establish
$150,000,000 in financial responsibility. Under the proposed rule, financial
responsibility could be established through insurance, guaranty, indemnity,
surety bond, letter of credit, qualification as a self-insurer or a combination
thereof. There is substantial uncertainty as to whether insurance companies or
underwriters will be willing to provide coverage under OPA because the statute
provides for direct lawsuits against insurers who provide financial
responsibility coverage, and most insurers have strongly protested this
requirement. The financial tests or other criteria that will be used to judge
self-insurance are also uncertain. Recently, parties in congress and industry
have been raising substantial objections to the rules as proposed by the MMS.
Various proposals have been made to resolve the objections of industry while
satisfying environmental concerns. The Company cannot predict the final form of
the financial responsibility rule that will be adopted by the MMS, but such rule
has the potential to result in the imposition of substantial additional annual
costs on the Company or otherwise materially adversely affect the Company. The
impact of the rule, however, should not be any more adverse to the Company than
it will be to other similarly situated owners or operators in the Gulf of
Mexico.
 
     The operators of the Company's properties have numerous applications
pending before the Environmental Protection Agency (the "EPA") for National
Pollution Discharge Elimination System water discharge permits with respect to
offshore drilling and production operations. The issue generally involved is
whether effluent discharges from each facility or installation comply with the
applicable federal regulations. See "Legal Proceedings" for a discussion of
other environmental matters.
 
     The Company's onshore operations are subject to numerous United States
federal, state, and local laws and regulations controlling the discharge of
materials into the environment or otherwise relating to the protection of the
environment including CERCLA. Such regulations, among other things, impose
absolute liability on the lessee under a lease for the cost of clean-up of
pollution resulting from a lessee's operations, subject the lessee to liability
for pollution damages, may require suspension or cessation of operations in
affected areas, and impose restrictions on the injection of liquids into
subsurface aquifers that may contaminate groundwater. In addition, the recent
trend toward stricter standards in environmental legislation
 
                                       12
<PAGE>   14
 
and regulation may continue. For instance, production wastes as "hazardous
wastes" which would make the reclassified exploration and production wastes
subject to more stringent handling, disposal and clean-up requirements. If such
legislation were to be enacted, it could have a significant impact on the
operating costs of the Company, as well as the oil and gas industry in general.
State initiatives to further regulate the disposal of oil and gas wastes are
also pending in certain states, and these initiatives could have a similar
impact on the Company.
 
     The Company is asked to comment on the costs it incurred during the prior
year on capital expenditures for environmental control facilities and the amount
it anticipates incurring during the coming year. The Company believes that, in
the course of conducting its oil and gas operations, many of the costs
attributable to environmental control facilities would have been incurred absent
environmental regulations as prudent, safe oil field practice. During 1994, the
Company incurred capital expenditures of approximately $2,360,000 for
environmental control facilities, including the completion of four salt water
disposal facilities in New Mexico. The Company currently has budgeted
approximately $1,300,000 for environmental control facilities, including three
salt water disposal facilities during 1995.
 
  Other Laws and Regulations
 
     Various laws and regulations often require permits for drilling wells and
also cover spacing of wells, the prevention of waste of oil and gas including
maintenance of certain gas/oil ratios, rates of production and other matters.
The effect of these laws and regulations, as well as other regulations that
could be promulgated by the jurisdictions in which the Company has production,
could be to limit allowable production from the Company's properties and thereby
to limit its revenues.
 
  Other Regulations and Legislative Proposals
 
     Prior to January 1, 1993 various aspects of the Company's natural gas
operations were subject to regulations by the FERC under the Natural Gas Act of
1938 (the "NGA") and the Natural Gas Policy Act of 1978 (the "NGPA") with
respect to "first sales" of natural gas including price controls and certificate
and abandonment authority regulations. However, as a result of the enactment of
the Natural Gas Decontrol Act of 1989, the remaining "first sales" restrictions
imposed by the NGA and the NGPA terminated on January 1, 1993.
 
     Commencing in late 1985, the FERC has issued a series of orders that have
had a major impact on natural gas pipeline operations, services and rates and
thus have significantly altered the marketing and price of natural gas. Order
636, issued in April 1992, requires each pipeline company, among other things,
to "unbundle" its traditional wholesale services and create and make available
on an open and nondiscriminatory basis numerous constituent services (such as
gathering services, storage services, firm and interruptible transportation
services, and stand-by sales services) and to adopt a new rate making
methodology to determine appropriate rates for those services. To the extent the
pipeline company or its sales affiliate makes gas sales as a merchant in the
future, it will do so in direct competition with all other sellers pursuant to
private contracts; however, pipeline companies and their affiliates are not
required to remain "merchants" of gas, and some of the interstate pipelines
companies have or will become "transporters only." In subsequent orders, the
FERC largely affirmed Order 636 and denied a stay of the implementation of the
new rules pending judicial review. In addition, the FERC has generally accepted
rate filings implementing Order 636 on essentially every interstate pipeline as
of the end of 1994. Order 636, as well as the FERC orders approving the
individual pipeline rate filings implementing Order 636, are the subject of
numerous appeals to the United States Courts of Appeals. The Company cannot
predict whether the latest orders will be affirmed on appeal or what the effects
will be on its business.
 
EMPLOYEES
 
     As of December 31, 1994, the Company had 108 employees. None of the
Company's employees are presently represented by a union for collective
bargaining purposes. The Company considers its relations with its employees to
be excellent.

ITEM 2. PROPERTIES.
 
     The information appearing in Item 1 of this Annual Report is incorporated
herein by reference.
 
PRINCIPAL PROPERTIES
 
     As of January 1, 1995, approximately 81% of the Company's domestic proved
oil and gas equivalent reserves and approximately 63% of the Company's total
proved oil and gas equivalent reserves were located on properties in the Gulf of
Mexico. Six significant producing areas, of which five are located in the Gulf
of Mexico and the sixth is located in New Mexico, accounted for approximately
56% of the estimated proved natural gas reserves and approximately 72% of the
estimated oil, condensate and natural gas liquids reserves of the Company as of
January 1, 1995. These producing areas accounted for approximately 83% of
natural gas production and 94% of oil, condensate and natural gas liquids
production for 1994. Net proved reserves, as estimated by Ryder Scott, and
average net daily production data for the six significant producing areas are
shown in the following table. No other major producing area accounted for more
than 5% of the estimated discounted future net revenues attributable to the
Company's estimated proved reserves as of January 1, 1995. However, the
Company's Thailand concession, which is currently not a producing property,
accounts for approximately 23% of the Company's total estimated net proved
reserves of natural gas, approximately 23% of the Company's total estimated net
proved reserves of oil, condensate and natural gas liquids and approximately 23%
of the Company's total net proved oil and gas equivalent reserves.

     Set forth below are descriptions of certain of the Company's significant
producing areas. Unless otherwise specifically identified, the information set
forth in such descriptions, including the number of wells, platforms and blocks,
is presented on a gross, rather than a net to the Company basis.
 
  Eugene Island
 
     The Company's most significant reserves and production are located in the
Eugene Island area off the Louisiana coast in the Gulf of Mexico. The Eugene
Island area has been an important part of the Company's operations since the
first lease in that area was purchased in 1970 and production began in 1973. The
Company currently holds interests in 13 blocks in the Eugene Island area. These
blocks comprise eight fields containing 94 oil and gas wells producing from
multiple reservoirs and horizons.
 
     The Eugene Island Block 330 field is the Company's most significant asset,
with 28 productive Pleistocene horizons between 4,000 and 8,000 feet, containing
multiple reservoirs. The field, located in 245 feet of water, contains three
drilling and production platforms in which the Company holds a 35% working
 
                                       14
<PAGE>   16
 
interest, as well as an additional platform in which the Company holds a 30%
working interest. There are currently 17 wells producing primarily natural gas
and 36 wells producing primarily oil on the block. In 1994, a successful
drilling program off of the field's "D" platform resulted in the completion of
three oil wells and one high volume horizontal gas well. Since initial
production in 1973, the Eugene Island Block 330 field has produced approximately
641 billion cubic feet ("Bcf ") of natural gas and 127 million barrels
("MMBbls") of oil and condensate (173 Bcf and 37 MMBbls attributable to the
Company's net revenue interest). Reserves have been added to this field
consistently since production commenced. These increases have been derived from
new exploratory horizons, infill drilling, field expansions and higher than
anticipated recovery efficiencies.
 
     Another significant field to the Company is the Eugene Island Block 295
field. On production since February 1973, this block has recorded gross
production of over 416 Bcf of natural gas and over 3.0 MMBbls of oil and
condensate during its twenty two-year life. In August 1993, the Company effected
an exchange of working interests in Eugene Island Block 295 with another working
interest owner in such block. Pursuant to this exchange, the Company increased
its working interest in Eugene Island Block 295 to 100% on 3,125 acres above
3,000 feet, to 20% on 1,875 acres above 3,000 feet and to 20% on all of the
block below 3,000 feet. During the fourth quarter of 1993, the Company
successfully drilled and completed five horizontal wells to exploit the natural
gas potential located in certain shallow reservoirs on this block in an area
where it has a 100% working interest. A platform was set and production
commenced from these wells in late February 1994. In September 1994, an
additional horizontal well was also drilled from this platform. Production from
this field is largely responsible for the substantial increase in the Company's
average daily production of natural gas from the Eugene Island area for 1994,
compared to 1993.
 
     The Eugene Island Block 212 field consists of Eugene Island Blocks 211 and
212 and Ship Shoal Block 175. The field contains eight productive horizons which
have four oil wells and two natural gas wells producing from a platform set in
1985. The Company and its partners completed a successful three well workover
and recompletion program in this field during the fourth quarter of 1994.
 
  Main Pass
 
     The Company's nine blocks in the Main Pass area are located near the mouth
of the Mississippi River in the Gulf of Mexico and include leases purchased from
1974 to 1992. The primary drilling objectives in these fields are Pliocene and
Miocene sandstone reservoirs with productive formation depths from 5,000 to
12,000 feet. The Company's interests in the Main Pass area include 42 producing
oil and gas wells producing from six platforms.
 
     A field including Main Pass Blocks 72, 73 and 72/74 was unitized in 1982
with the Company's working interest at 14%. In late 1994, the Company increased
its working interest in this field to 35% by purchasing another working interest
owner's interests in the field. This field contains 23 producing oil wells and 8
producing natural gas wells from three platforms operated by one of the
Company's joint venture partners. The field is located in 125 feet of water with
38 mapped horizons adjacent to and surrounding a salt dome. These horizons
contain over 150 separate reservoirs between 5,000 and 12,000 feet. A successful
10 well workover program in this field was completed in 1994. In addition, the
first three wells of a four well development program were drilled in 1994. The
Company currently plans to continue its workover program and drill six
additional wells in this field during 1995 based in part on the analysis of a
proprietary 3-D seismic survey over the field that the Company acquired rights
to in 1994.
 
     Main Pass Block 123 was acquired in the federal lease sale of 1990. Pogo
Gulf Coast, for which the Company is the general partner, has a 75% working
interest and is the operator on the block. Along with its non-operating joint
venture partner, Pogo Gulf Coast drilled two discovery wells on the block in
1993. Subsequently, Pogo Gulf Coast drilled two additional wells on this block
in 1994. Installation of a platform and construction of a pipeline from the
platform to an existing main pipeline was completed in January 1995. Platform
start-up was completed and full production from this field commenced in February
1995.

  South Marsh Island
 
     The Company currently owns interests in portions of seven blocks in the
South Marsh Island area, located offshore Louisiana. Three of the leases were
acquired in 1974, a fourth in 1980, a fifth in 1992 and portions of two more
leases were acquired in 1994 through farmins. Three blocks contain a total of
five drilling and production platforms. These platforms currently have 44 oil
and gas wells producing from Pleistocene age sandstone reservoirs located at
depths from 5,000 to 10,000 feet.
 
     The South Marsh Island Block 128 field, in which the Company owns a 16%
working interest, comprises South Marsh Island Blocks 125, 127, 128 and 141.
This field primarily produces oil, with 32 oil wells and eight natural gas wells
producing from 20 separate reservoirs. In 1994, a five well drilling program in
this field was completed which resulted in increased oil and gas deliverability
and reserves. Additional drilling is currently planned for 1995. The wells that
were drilled in 1994 and those planned for 1995 have been based on the ongoing
analysis of a 3-D seismic survey in conjunction with a detailed reservoir study
of the field.
 
     The Company also owns a 25% working interest in the South Marsh Island
Block 160 field which is producing from three oil wells at a depth of
approximately 9,700 feet. A single platform was set on this block in 1983. A
two-well drilling program in this field resulting from analysis of a 3-D seismic
survey covering the field was completed in the fourth quarter of 1994.
 
  South Pass
 
     The Company acquired its first South Pass area leasehold interest in
September 1972. The Company currently owns interests in portions of six blocks
in this area on which four production platforms have been set that produce oil
and gas from 27 wells which have been completed principally in Pleistocene,
Pliocene and Miocene reservoirs at depths ranging from approximately 4,000 to
14,800 feet.
 
     The Company's most significant field in the South Pass area is located on
South Pass Blocks 49 and 50. The Company increased its working interest in South
Pass Bock 49 from 6% to 20% late in 1994. In addition, in late 1993, the Company
successfully completed the drilling of a highly deviated well into two
reservoirs on South Pass Block 50, in which the Company holds a 50% working
interest, from a platform located on South Pass Block 49 that substantially
increased the Company's production from this area.
 
  East Cameron
 
     Production commenced from the Company's first East Cameron area leasehold
interest in February 1973. Presently, the Company has interests in 3 offshore
blocks in this area which contain two fields and 13 producing gas wells.
 
     During 1992, the Company and its partners conducted a 3-D seismic survey of
the East Cameron Block 334/335 field area where the Company has a 42% working
interest. Analysis of this 3-D seismic survey resulted in the drilling of four
successful development wells. As of February 1, 1995, an exploratory well was
also being drilled on East Cameron Block 334.
 
  New Mexico
 
     The Company considers southeastern New Mexico to be an area of significant
growth in both production and reserves as a result of recent exploration and
development activities. The Company believes that during the past four years it
has been one of the most active companies drilling for oil and natural gas in
the southeastern New Mexico (Lea and Eddy Counties) portion of the Permian Basin
where the Company has interests in over 70,000 gross acres. The Company's
primary drilling objective for crude oil is the Brushy Canyon (Delaware)
formation. Fields in the Brushy Canyon (Delaware) formation in the southeastern
New Mexico portion of the Permian Basin are generally characterized by
production from relatively shallow depths (6,000 to 9,000 feet), multiple
producing zones in most wells and relatively high initial rates of production
(frequently equaling the top field allowables which range from of 142 Bbls to
230 Bbls per day, depending on the depth of production from the field). The
Company has achieved rapid cost recovery with respect to its New Mexico wells
drilled to date because of relatively low capital costs and high initial rates
of production.

<PAGE>   18
 
     Since the Company began exploring in the Brushy Canyon (Delaware) formation
in October 1989, it has participated in the drilling of 209 wells through
December 31, 1994, including, among others, 84 wells in the Sand Dunes field
where the Company's working interest ranges from 4% to 89%, 27 wells in the East
Loving field where the Company's working interest ranges from 33% to 98%, 45
wells in the Livingston Ridge field where the Company's working interest ranges
from 25% to 100%; and 29 wells in the Red Tank field where the Company's working
interest ranges from 89% to 100%. The oil fields in this area are generally
developed on a 40 acre spacing pattern. The Company anticipates drilling many
additional locations in these and other fields in southeastern New Mexico during
1995 and in future years.

ITEM 3. LEGAL PROCEEDINGS.
 
     In 1989, a large number of exploration and production companies, including
the Company, were circularized with Special Notice Letters in accordance with
CERCLA from the EPA regarding a particular waste disposal site in Louisiana
known as the "Gulf Coast Vacuum Site" utilized by a trucking company. The EPA
subsequently developed a list based on its investigation showing the Company
bearing an approximate 1% responsibility for this site based on the trucking
company's shipping records. The Company utilized the trucking company to dispose
of salt water produced from a well in which the Company had an interest. The
Company, however, believes that none of this salt water was delivered to the
Gulf Coast Vacuum Site. In any
 
                                       19
<PAGE>   21
 
event, the Company believes that the trucking company shipped only oilfield
waste for the Company which is exempt pursuant to CERCLA and, further, that such
shipments, if any, were sent to a properly permitted waste disposal site. The
Company has learned that the EPA has recently entered a consent decree, the
details of which have not been made fully public, with certain parties that are
believed to be responsible for a majority of the disposal occurring at the site.
 
     The Company is a party to various other legal proceedings consisting of
routine litigation incidental to its businesses, but believes that any potential
liabilities resulting from these proceedings are adequately covered by insurance
or are otherwise immaterial at this time.

ITEM 5. MARKET FOR THE REGISTRANT'S COMMON STOCK AND RELATED SECURITY HOLDER
MATTERS.
 
     The following table shows the range of low and high sales prices of the
Company's Common Stock (the "Common Stock") on the New York Stock Exchange
composite tape where the Company's common stock trades under the symbol PPP. The
Company's common stock is also listed on the Pacific Stock Exchange.
 
     In 1994, the Company paid $0.06 per share in dividends on its Common Stock
since it commenced paying dividends in August 1994. In this regard, the Company
reinstated the practice of declaring a quarterly cash dividend commencing in the
third quarter of 1994. However, the declaration and payment of future dividends
will depend upon, among other things, the Company's future earnings and
financial condition, liquidity and capital requirements, the general economic
and regulatory climate and other factors deemed relevant by the Company's Board
of Directors.
 
     Pursuant to the Company's revolving credit agreement with its banks under
which the Company has borrowed funds, the Company may not, subject to certain
exceptions, pay any dividends on its capital stock or make any other
distributions on shares of its capital stock (other than dividends or
distributions payable solely in shares of such capital stock) or apply any
funds, property or assets to the purchase, redemption, sinking fund or other
retirement of its capital stock, if the aggregate amount of all such dividends,
purchases, and redemptions would exceed an amount determined based on the
consolidated income of the Company and its consolidated subsidiaries from and
after a specified date plus the proceeds of the issuance of capital stock after
the same specified date or if the net worth of the Company is negative. As of
December 31, 1994, $64,037,000 was available for dividends under this
limitation.

ITEM 7.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
       OF OPERATIONS.
 
RESULTS OF OPERATIONS
 
     The Company reported net income for 1994 of $27,067,000 or $0.81 per share
(on both a primary and fully diluted basis) compared to net income for 1993 of
$25,061,000 or $0.76 per share (on both a primary and fully diluted basis) and
net income for 1992 of $18,495,000 or $0.66 per share (on both a primary and
fully diluted basis). Included in net income for 1994 is an extraordinary loss
of $307,000 (net of taxes) or $0.01 per share in connection with the retirement
of the Company's 10.25% Convertible Subordinated Notes, due 1999 (the "10.25%
Notes") on April 18, 1994. Earnings per common share are based on the weighted
average number of common and common equivalent shares outstanding for 1994 of
33,352,000 compared to 32,860,000 for 1993 and 27,929,000 for 1992. The
increases in the weighted average number of common and common equivalent shares
outstanding for 1993 resulted primarily from the issuance of 4,500,000 shares of
common stock in December 1992 as set forth in the Consolidated Statements of
Shareholders' Equity included in "Item 8. Financial Statements and Supplementary
Data." The increases in the weighted average number of common and common
equivalent shares outstanding for 1994 resulted from the issuance of shares of
common stock upon the exercise of stock options pursuant to the Company's stock
option plans. Earnings per common share computations on a fully diluted basis
would reflect additional common shares issuable upon the assumed conversion of
the Company's 5 1/2% Convertible Subordinated Notes, due 2004 (the "5 1/2%
Notes") (the only convertible securities of the Company that were dilutive
during the applicable periods) and the elimination of related interest
requirements, as adjusted for applicable federal income taxes. However, the
dilution resulting from the assumed conversion of the 5 1/2% Notes was not
sufficient to change reported earnings per share.
 
     The Company's total revenues for 1994 were $173,608,000, an increase of
approximately 24% from total revenues of $139,554,000 for 1993, and an increase
of approximately 23% from total revenues of $140,830,000 for 1992. The increase
in the Company's total revenues for 1994, compared to 1993 and 1992, resulted
primarily from increased natural gas, crude oil, condensate and natural gas
liquid ("NGL") production volumes. Partially offsetting volume increases were
substantial decreases in the prices that the Company received for its crude oil
and condensate production volumes. In addition, the Company's total revenues for
1993 and 1992 were positively affected by revenues from settlement of an issue
with the Internal Revenue Service and gains related to the sale of non-strategic
properties.
 
     The Company's oil and gas revenues for 1994 were $173,556,000, an increase
of approximately 27% from oil and gas revenues of $136,553,000 for 1993, and an
increase of approximately 25% from oil and gas revenues of $139,128,000 for
1992. The following table reflects an analysis of variances in the Company's oil
and gas revenues between 1994 and the previous two years:

     Average natural gas prices received by the Company for the two years prior
to 1994 were volatile and marked by non-seasonal as well as seasonal variations.
The average price per Mcf that the Company received for its natural gas
production increased during 1993, compared to 1992, averaging $1.75 per Mcf for
1992 and $1.98 per Mcf for 1993. Prices increased throughout 1993, partially as
a result of severe late winter weather that drew down natural gas storage
supplies which, coupled with relatively high crude oil prices that inhibited
fuel switching from natural gas to residual heating oil at that time, created a
substantial demand in the spring and the summer to replenish depleted storage
facilities and to supply natural gas for the industrial and electric generation
markets. Notwithstanding severe winter weather during January and February of
1994 that led to record low natural gas storage levels in March, rapid injection
of natural gas into storage coupled with a mild summer contributed to a
substantial decline in natural gas prices during the second half of 1994
resulting in the Company receiving an average price of $1.88 per Mcf for its
natural gas production during 1994 which, while it was 5% less than the average
price that the Company received in 1993, was still an increase of 7% over the
average price that the Company received in 1992. See "Business -- Miscellaneous;
Competition and Market Conditions." Natural gas production for 1994 averaged
144.8 MMcf per day, an increase of approximately 58% from average production of
91.7 MMcf per day in 1993, and an increase of approximately 38% from average
production of 105.2 MMcf per day for 1992. The increase in the Company's average
natural gas production for 1994, compared to 1993 and 1992, was related
primarily to natural gas production from the Company's Eugene Island Block
295"B" platform from which production commenced in late February 1994, and the
continued success of the Company's ongoing active offshore and onshore drilling
and workover programs, which was partially offset by a natural decline in
deliverability from some of the Company's more mature properties.
 
     As of January 1, 1995, the Company had entered into futures contracts with
various parties on a portion of its daily natural gas production through
September 30, 1995 (commencing with contracts totaling approximately 37 MMcf per
day in January and decreasing on a quarterly basis to approximately 15 MMcf per
day) at varying prices ranging from approximately $1.92 to $1.83 per Mcf.
 
     Crude oil and condensate prices received by the Company averaged $16.08 per
barrel in 1994 compared to $17.81 per barrel in 1993 and $20.17 per barrel in
1992. Crude oil and condensate prices were relatively stable during 1992 and the
first six months of 1993. However, commencing in July 1993, the average price
per barrel that the Company received for its production began dropping until, by
December 1993, the average price per barrel for crude oil and condensate that
the Company received for its production during that month averaged only $13.39
per barrel. However, the average price per barrel that the Company received for
its crude oil and condensate production began recovering in June 1994 and showed
gradual improvement throughout the remainder of the year. For the month of
December 1994, the average price per barrel that the Company received for its
crude oil and condensate production was $16.44. Crude oil and condensate
production for 1994 averaged 11,100 Bbls per day, an increase of approximately
13% from 9,851 Bbls per day for 1993, and an increase of approximately 28% from
8,699 Bbls per day for 1992. The increase in the Company's crude oil and
condensate production for 1994, compared to 1993 and 1992, resulted primarily
from ongoing development programs principally in the Main Pass, Eugene Island
and South Pass areas, together with the acquisition by the Company of additional
working interests in certain leases in the Main Pass area. See "Properties --
Principal Properties" and "Business -- Domestic Offshore Operations; Lease
Acquisitions."
 
     As of February 1, 1995, the Company had entered into a crude oil swap
agreement with another party in which it had swapped the floating market price
it receives from purchasers of its crude oil for a fixed price of $17.08 per
barrel on 1,000 Bbls per day of the Company's production for a period ending
April 30, 1995. See "Business -- Miscellaneous; Sales."
 
     Liquid products are often extracted from natural gas streams and sold
separately as NGL. The Company's NGL production averaged 2,222 Bbls per day for
1994, an increase of approximately 32% from an average of 1,678 Bbls per day for
1993 and an increase of approximately 88% from an average of 1,181 Bbls per day
for 1992. The increase in the Company's NGL production during 1994, compared to
1993 and 1992, resulted primarily from extracting liquids from several new high
Btu content wells and increased production generally.
 
                                       24
<PAGE>   26
 
     The Company's total liquids production during 1994, including crude oil,
condensate and NGL, averaged 13,322 Bbls per day, an increase of approximately
16% from an average total liquids production of 11,529 Bbls per day for 1993,
and an increase of approximately 35% from an average total liquids production of
9,880 Bbls per day for 1992.
 
     The Company's oil and gas revenues for 1994, 1993 and 1992 also reflect
adjustments for various miscellaneous items. For 1993 and 1992, the Company made
adjustments to its net income to reflect the settlement of certain litigation
with the State of Louisiana regarding past royalty disputes pertaining to the
Company's offshore state leases. For 1993, additional adjustments were also made
to reflect an agreement with the MMS to allow the Company to offset FERC Order
93A payments previously made by the Company on behalf of the MMS against FERC
Order 94A obligations due from the Company and the resulting overaccrual of
related interest expenses.
 
     Lease operating expenses for 1994 were $29,768,000, an increase of
approximately 12% from lease operating expenses of $26,633,000 for 1993, and an
increase of approximately 15% from lease operating expenses of $25,842,000 for
1992. The increase in lease operating expenses for 1994, compared to 1993 and
1992, resulted primarily from increased operating activity on existing
properties, including increased operating costs related to additional properties
brought on production in 1994. However, primarily as a result of increased
production of natural gas, crude oil, condensate and NGLs by the Company during
1994, compared to 1993 and 1992, the Company's lease operating expenses were
only $0.36 per equivalent Mcf for 1994, a decrease of 20% from lease operating
expenses of $0.45 per equivalent Mcf for 1993, and a decline of approximately
16% from lease operating expenses of $0.43 per equivalent Mcf for 1992.
 
     General and administrative expenses for 1994 were $15,984,000, an increase
of approximately 10% from general and administrative expenses of $14,550,000 for
1993, and an increase of approximately 22% from general and administrative
expenses of $13,129,000 for 1992. The increase in general and administrative
expenses for 1994, compared to 1993 and 1992, was related to, among other
things, an increase in the number of Company employees resulting from the
Company's increased exploration and production related activities and to normal
salary and concomitant benefit expense adjustments.
 
     Exploration expenses consist primarily of delay rentals and geological and
geophysical costs which are expensed as incurred. Exploration expenses for 1994
were $5,257,000, an increase of approximately 114% from exploration expenses of
$2,455,000 for 1993, and an increase of approximately 69% from exploration
expenses of $3,102,000 for 1992. The increase in exploration expenses for 1994,
compared to 1993 and 1992, resulted primarily from increased geophysical
activity by the Company, including the costs of conducting and processing
several proprietary 3-D seismic surveys on Company leases in South Texas, West
Texas and the Gulf of Thailand, together with the cost of acquiring several
non-proprietary 3-D seismic surveys in the Gulf of Mexico.
 
     Dry hole and impairment expenses relate to costs of unsuccessful wells
drilled along with impairments to the associated unproved property costs and
impairments to previously proved property costs as a result of decreases in
expected reserves. The Company's dry hole and impairment expenses for 1994 were
$7,088,000, an increase of approximately 51% from dry hole and impairment costs
of $4,690,000 for 1993, but a decrease of approximately 24% from dry hole and
impairment costs of $9,314,000 for 1992.
 
     The Company accounts for its oil and gas activities using the successful
efforts method of accounting. Under the successful efforts method, lease
acquisition costs and all development costs are capitalized. Unproved properties
are reviewed quarterly to determine if there has been impairment of the carrying
value, with any such impairment charged to expense in the period. Exploratory
drilling costs are capitalized until the results are determined. If proved
reserves are not discovered, the exploratory drilling costs are expensed. Other
exploratory costs are expensed as incurred.
 
     The provision for depreciation, depletion and amortization ("DD&A") is
based on the capitalized costs mentioned in the preceding paragraph plus future
costs to abandon offshore wells and platforms and is determined on a
field-by-field basis using the units of production method. The Company's DD&A
expense for 1994 was $63,308,000, an increase of approximately 56% from DD&A
expenses of $40,693,000 for 1993, and
 
                                       25
<PAGE>   27
 
an increase of approximately 50% from DD&A expenses of $42,302,000 for 1992. The
increases in the Company's DD&A expenses for 1994, compared to 1993 and 1992,
resulted primarily from increased volumes produced (largely related to the
increased natural gas production discussed above) and, to a lesser extent, an
increase in the composite DD&A rate. The composite DD&A rate for all of the
Company's producing fields for 1994 was $0.77 per equivalent Mcf ($4.59 per
equivalent barrel), an increase of approximately 12% from a composite DD&A rate
of $0.69 per equivalent Mcf ($4.11 per equivalent barrel) for 1993, and an
increase of 10% from a composite DD&A rate of $0.70 per equivalent Mcf ($4.17
per equivalent barrel) for 1992. The Company produced 82,008,000 equivalent Mcf
(13,668,000 equivalent barrels) in 1994, an increase of approximately 40% from
the 58,718,000 equivalent Mcf (9,786 equivalent barrels) produced in 1993, and
an increase of approximately 36% from the 60,189,000 equivalent Mcf (10,032,000
equivalent barrels) produced in 1992. See "Financial Statements and
Supplementary Data -- Note 1 of Notes to Consolidated Financial Statements ."
 
     Interest charges for 1994 were $10,104,000, a decrease of approximately 8%
from interest charges of $10,956,000 for 1993, and a decrease of approximately
47% from interest charges of $19,036,000 for 1992. The decrease in interest
charges for 1994, compared to 1993 and 1992, was related primarily to decreased
debt issue amortization expenses, lower average interest rate levels on the debt
outstanding (as a result of refinancing certain debt discussed in "-- Liquidity
and Capital Resources" below), and, as compared to 1992, a decrease in the
amount of debt outstanding. These decreases in interest charges for 1994,
compared to 1993 and 1992, were partially offset by increased commitment fees
resulting from increased availability under the Company's bank revolving credit
facility and, as compared to 1993, an increase in debt outstanding. See
"Financial Statements and Supplementary Data -- Note 3 of Notes to Consolidated
Financial Statement."
 
     Income tax expense for 1994 was $15,517,000, an increase of approximately
4% from income tax expense of $14,981,000 for 1993, and an increase of
approximately 52% from income tax expense of $10,192,000 for 1992. The increases
in income tax expense are related to increases in profitability and to the
effective tax rates of 36.2% in 1994, 37.5% in 1993 and 35.5% in 1992. The
variances in the effective tax rates are primarily related to the expenses
incurred by the Company's subsidiary in Thailand which are not included in the
Company's consolidated U.S. federal income tax returns.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company's Consolidated Statement of Cash Flows for the year ended
December 31, 1994, reflects net cash provided by operating activities of
$99,273,000. In addition to the net cash provided by operating activities, the
Company also received $3,687,000 from the exercise of stock options. Other
significant cash receipts and disbursements during 1994 included the following.
The Company issued and sold $86,250,000 of 5 1/2% Notes in March 1994, and had
net borrowings of $7,000,000 under uncommitted money market credit lines with
certain banks. The Company invested $85,375,000 of such cash flow in capital
projects during 1994, purchased certain proved reserves for $32,578,000, prepaid
the remaining outstanding principal and prepayment fee on its 10.25% Notes
($24,472,000), made net payments of $53,000,000 on the Company's revolving
credit facility, paid $2,446,000 of issuance expenses in connection with its
offering of the 5 1/2% Notes and paid $1,966,000 ($0.06 per share) in dividends
to holders of the Company's common stock. Of the $85,375,000 invested in capital
projects, $22,955,000 was applicable to 1993 projects and $62,420,000 was
applicable to 1994 capital projects. The Company's total debt at December 31,
1994, was $150,531,000, an increase of approximately 12% from total debt of
$134,539,000 at December 31, 1993. The increase in the Company's total debt
resulted primarily from the purchase of certain proved reserves in the fourth
quarter of 1994. As of December 31, 1994, the Company had $2,922,000 in cash and
cash investments.
 
     The Company's capital and exploration budget for 1995, which does not
include any amounts which may be expended for the purchase of proved reserves or
any interest which may be capitalized resulting from projects in progress, was
established by the Company's Board of Directors in January 1995, at
$100,000,000, an increase of approximately 13% from the Company's capital and
exploration expenditures (excluding purchased reserves and interest capitalized)
of $88,300,000 for 1994, an increase of approximately 34% over capital and
exploration expenditures (excluding capitalized interest) of $74,600,000 for
1993, and an increase of approximately 209% over capital and exploration
expenditures (excluding purchased reserves and interest capitalized) of
approximately $32,400,000 for 1992.
 
                                       26
<PAGE>   28
 
     In addition to anticipated capital and exploration expenses, other material
1995 cash requirements that the Company currently anticipates include ongoing
operating, general and administrative, income tax, and interest expense, sinking
fund payments and the payment of dividends on its common stock, including a
$0.03 per share dividend on its common stock to be paid February 28, 1995, to
stockholders of record on February 10, 1995. The Company currently anticipates
that cash provided by operating activities and funds available under its Credit
Agreement and uncommitted money market credit lines will be sufficient to fund
the Company's ongoing expenses, its 1995 capital and exploration budget and
anticipated future dividend payments. In this regard, the Company reinstated the
practice of declaring a quarterly dividend commencing in the third quarter of
1994. However, the declaration and payment of future dividends will depend upon,
among other things, the Company's future earnings and financial condition,
liquidity and capital requirements, the general economic and regulatory climate
and other factors deemed relevant by the Company's Board of Directors.
 
     The Company's amended bank credit agreement (the "Credit Agreement")
currently provides for a $100,000,000 revolving/term credit facility which will
be fully revolving until June 29, 1996, after which the balance will be due in
eight quarterly term loan installments, commencing July 31, 1996. The amount
that may be borrowed under the Credit Agreement may not exceed a borrowing base,
determined semiannually by the lenders in accordance with the Credit Agreement
based on the discounted present value of certain of the Company's oil and gas
reserves. The borrowing base currently exceeds $100,000,000. The Credit
Agreement is governed by various financial and other covenants, including
requirements to maintain positive working capital (excluding current maturities
of debt), a fixed charge coverage ratio, and limitations on the prepayment
(without refinancing) of subordinated debt, the payment of dividends, mergers
and consolidations, and asset dispositions. See "Market for the Registrant's
Common Stock and Related Security Holder Matters." Upon the occurrence or
declaration of certain events, the banks would be entitled to a security
interest in the borrowing base properties, which include most of the Company's
domestic properties. Borrowings under the Credit Agreement currently bear
interest at a Base (Prime) rate, a certificate of deposit rate plus 1 5/8%, or
LIBOR plus 1 1/2%, at the Company's option. A commitment fee of 1/2 of 1% per
annum of the unborrowed amount under the Credit Agreement is also due.
 
     The Company has also entered into separate letter agreements with two banks
under which each bank may provide a $10,000,000 uncommitted money market line of
credit. The two lines of credit are on an as available or offered basis and
neither bank has an obligation to make any advances under its respective line of
credit. Although loans made under these letter agreements are for a maximum term
of 30 days, they are reflected as long-term debt on the Company's balance sheet
because the Company currently has the ability and intends to reborrow such
amounts under its Credit Agreement. Both letter agreements permit either party
to terminate such letter agreement at any time. Under its Credit Agreement, the
Company is currently limited to incurring a maximum of $10,000,000 of additional
senior debt, which would include debt incurred under these lines of credit. As
of December 31, 1994, indebtedness in the principal amount of $21,000,000 was
outstanding under the Credit Agreement and the two letter agreements.
 
     The outstanding principal amount of 5 1/2% Notes was $86,250,000 as of
December 31, 1994. The 5 1/2% Notes are convertible into Common Stock at $22.188
per share subject to adjustment upon the occurrence of certain events. The
5 1/2% Notes will be redeemable at the option of the Company, in whole or in
part, at any time on or after March 15, 1998, at a redemption price of 103.3% of
their principal amount and decreasing percentages thereafter. No sinking fund
payments are required on the 5 1/2% Notes. The 5 1/2% Notes are redeemable at
the option of the holder, upon the occurrence of a repurchase event (a change of
control as defined in the indenture governing the 5 1/2% Notes), at 100% of the
principal amount.
 
     The outstanding principal amount of the 8% Convertible Subordinated
Debentures, due 2005 (the "8% Debentures") was $43,281,000 as of December 31,
1994. The 8% Debentures are convertible into Common Stock at $39.50 per share,
subject to adjustment in certain circumstances, including stock splits. The 8%
Debentures are redeemable at the option of the Company at 102.4% of their
principal amount through December 30, 1995, and decreasing percentages
thereafter, and are subject to mandatory annual sinking fund requirements of
$3,000,000, due each December, with a final maturity of December 31, 2005. The
sinking fund requirements for the 8% Debentures will be sufficient to retire all
but $15,000,000 of the issue prior to
 
                                       27

maturity. The Company currently has purchased $1,718,000 face amount of 8%
Debentures which it may tender in satisfaction of future sinking fund
requirements. See "Financial Statements and Supplementary Data -- Note 3 to
Notes to Consolidated Financial Statements."
 
OTHER MATTERS
 
     Publicly held companies are asked to comment on the effects of inflation on
their business. Currently annual inflation in terms of the decrease in the
general purchasing power of the dollar is running much below the general annual
inflation rates experienced in the past. While the Company, like other
companies, continues to be affected by fluctuations in the purchasing power of
the dollar, such effect is not currently considered significant.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Shareholders and Board of Directors of Pogo Producing Company:
 
     We have audited the accompanying consolidated balance sheets of Pogo
Producing Company (a Delaware corporation) and subsidiaries as of December 31,
1994 and 1993, and the related consolidated statements of income, shareholders'
equity and cash flows for each of the three years in the period ended December
31, 1994. These financial statements are the responsibility of Pogo's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Pogo Producing Company and
subsidiaries as of December 31, 1994 and 1993, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1994, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation --
 
     The consolidated financial statements include the accounts of Pogo
Producing Company and its wholly-owned subsidiaries (the "Company"), after
elimination of all significant intercompany transactions.
 
  Inventories --
 
     Inventories consist primarily of tubular goods used in the Company's
operations and are stated at the lower of average cost or market value.
 
  Interest Capitalized --
 
     Interest costs related to financing major oil and gas projects in progress
are capitalized until the projects are evaluated.
 
  Earnings per Share --
 
     Earnings per common and common equivalent share (primary earnings per
share) are based on the weighted average number of shares of Common Stock and
common equivalent shares outstanding during the periods. The dilutive effect of
stock options was considered in the earnings per share reported for the periods.
The 8% Debentures are common stock equivalents and were anti-dilutive in all
periods. Earnings per common and common equivalent share assuming full dilution
(fully diluted earnings per share) considered the 10.25% Notes (retired on April
18, 1994) which were anti-dilutive in all periods in which they were outstanding
and the 5 1/2% Notes (issued on March 16, 1994) which were dilutive for the
portion of 1994 in which they were outstanding, but such dilution was not
sufficient to change reported earnings per share. Earnings per share are based
on the following:

</TABLE>
 
  Production Imbalances --
 
     Owners of an oil and gas property often take more or less production from a
property than entitled to based on their ownership percentages in the property.
This results in a condition known in the industry as a production imbalance. The
Company follows the "take" (cash) method of accounting for production
imbalances. Under this method, the Company recognizes revenues on production as
it is taken and delivered to its purchasers. The Company's crude oil imbalances
are not significant. At December 31, 1994, the

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Company had taken approximately 4,873 MMcf of natural gas less than it was
entitled to based on its interest in certain properties, and approximately 1,994
MMcf more than its entitlement in certain other properties placing the Company
at year end in a net under-delivered position of approximately 2,879 MMcf of
natural gas based on its working interest ownership in the properties.
 
  Oil and Gas Activities and Depreciation, Depletion, and Amortization --
 
     The Company follows the successful efforts method of accounting for its oil
and gas activities. Under the successful efforts method, lease acquisition costs
and all development costs are capitalized. Unproved properties are reviewed
quarterly to determine if there has been impairment of the carrying value, with
any such impairment charged to expense in the period. Exploratory drilling costs
are capitalized until the results are determined. If proved reserves are not
discovered, the exploratory drilling costs are expensed. Other exploratory costs
are expensed as incurred. The provision for depreciation, depletion and
amortization is based on the capitalized costs mentioned above plus future costs
to abandon offshore wells and platforms and is determined on a field-by-field
basis using the units of production method.
 
     Other properties are depreciated using a straight-line method in amounts
which in the opinion of management are adequate to allocate the cost of the
properties over their estimated useful lives.
 
  Consolidated Statements of Cash Flows --
 
     For the purpose of cash flows, the Company considers all highly liquid
investments with a maturity date of three months or less to be cash equivalents.
Significant transactions may occur which do not directly affect cash balances
and as such will not be disclosed in the Consolidated Statements of Cash Flows.
Certain such noncash transactions are disclosed in the Consolidated Statements
of Shareholders' Equity relating to the acquisition of treasury stock in 1993 in
exchange for stock options exercised and the conversion in 1993 of a debenture
into Common Stock. In addition, the Company in 1993, exchanged its working
interest in thirteen Gulf of Mexico oil and gas properties for an increased
working interest in five other Gulf of Mexico oil and gas properties in a
noncash "like kind" exchange. The oil and gas property and accumulated
depreciation, depletion and amortization accounts as reflected in the
Consolidated Balance Sheets have been adjusted to reflect the appropriate
amounts to record the working interests acquired and disposed of. The oil and
gas reserves acquired and disposed of are reflected as purchases and sales in
the "Estimates of Proved Reserves" roll forward included in the "Unaudited
Supplementary Financial Data" included elsewhere herein.
 
  Commitments and Contingencies --
 
     The Company's office rent expense was $819,000, $868,000, and $808,000 in
1994, 1993, and 1992, respectively. The Company has lease commitments for office
space of $822,000 in 1995, $1,039,000 in 1996 and 1997, $1,007,000 in 1998, and
$962,000 in 1999.

     The deferred federal income tax provision is the result of the difference
between deferred tax liabilities determined at each balance sheet date. The
deferred tax liabilities are determined by applying current tax laws to
temporary differences in the recognition of revenue and expense for tax and
financial purposes. The principal components of the Company's deferred income
tax liability include the following at December 31, 1994 and 1993 (expressed in

     The bank revolving credit agreement entered into in December, 1993, extends
to the Company a $100,000,000 revolving/term credit facility which will be fully
revolving until June 29, 1996 and will convert to a term loan with eight
quarterly installments commencing July 31, 1996. The amount that may be borrowed
under the facility may not exceed a borrowing base, determined semiannually by
the lenders based on the discounted present value of the Company's oil and gas
reserves and the provisions of the agreement. The borrowing base currently
exceeds $100,000,000. The agreement provides that total debt and total debt for
borrowed money, as defined, may not exceed $230,000,000 and $200,000,000,
respectively. The facility is governed by various financial covenants including
the maintenance of positive working capital (excluding current maturities of
debt), a fixed charge ratio, as defined, of 1.7 or greater, a $10,000,000 limit
on other senior debt, and a $10,000,000 limit on prepayment (without
refinancing) of subordinated debt in any one year and $20,000,000 in total
through July 31, 1996. Upon the occurrence of an event of default or certain
other specified events, the banks would be entitled to a security interest in
the borrowing base properties, which constitute substantially all of the
Company's domestic oil and gas properties. Borrowings under the facility bear
interest at a Base (Prime) rate, certificate of deposit rate plus 1 5/8%, or
LIBOR plus 1 1/2%, at the Company's option. A commitment fee of 1/2 of 1% per
annum of the unborrowed amount under the facility is

also due. The Company incurred commitment fees of $409,000 in 1994, $149,000 in
1993, and $80,000 in 1992 under this and a prior revolving credit agreement.
 
     The Company has entered into separate letter agreements with two banks
under which each bank may provide a $10,000,000 uncommitted line of credit. The
two $10,000,000 lines of credit are on an as available or offered basis and the
banks have no obligations to make any advances under the lines. Loans made under
the agreements are for a maximum term of 30 days and are reflected as long-term
as the Company has the intent and ability to reborrow such amounts under its
bank revolving credit agreement discussed above. The agreements may be
terminated at any time by the Company or either bank.
 
     The 5 1/2% convertible subordinated notes, due 2004 (the "5 1/2% Notes")
are convertible into Common Stock at $22.188 per share subject to adjustment
upon the occurrence of certain events. The 5 1/2% Notes will be redeemable at
the option of the Company, in whole or in part, at any time on or after March
15, 1998, at a redemption price of 103.3% and decreasing percentages thereafter.
No sinking fund is provided. The 5 1/2% Notes are redeemable at the option of
the holder, upon the occurrence of a repurchase event (a change in control, as
defined), at 100% of the principal amount.
 
     The 8% convertible subordinated debentures, due 2005 (the "8% Debentures")
are convertible into Common Stock at $39.50 per share subject to adjustments
under certain circumstances, including stock splits. The 8% Debentures are
redeemable at the option of the Company at 102.4% through December 30, 1995, and
decreasing percentages thereafter, and are subject to mandatory annual sinking
fund requirements of $3,000,000 which commenced December 31, 1990. Such
requirements will be sufficient to retire all but $15,000,000 of the issue prior
to maturity. As of December 31, 1994, the Company has purchased $13,998,000
principal amount of the bonds at less than face value resulting in both ordinary
and extraordinary gains. The Company has tendered $12,000,000 principal amount
of the bonds to the trustee in satisfaction of sinking fund requirements and
$280,000 principal amount of the bonds have been called by the trustee. The
Company currently has $1,718,000 principal amount of bonds purchased in excess
of current sinking fund requirements which may be tendered in satisfaction of
future sinking fund requirements.
 
     Current maturities and sinking fund requirements during the next five years
in connection with the above long-term debt are $1,282,000 in 1995, $9,300,000
in 1996, $13,500,000 in 1997, $7,200,000 in 1998 and $3,000,000 in 1999.
Included in the current maturities reflected above are $6,300,000 in 1996,
$10,500,000 in 1997, and $4,200,000 in 1998 relative to bank debt. The Company
has established a history of refinancing its bank debt before scheduled
maturities and expects to do so again before the amortization of bank debt
commences in 1996.

(5) CREDIT RISK
 
     Substantially all the Company's accounts receivable at December 31, 1994,
result from oil and gas sales and joint interest billings to other companies in
the oil and gas industry. This concentration of customers and joint interest
owners may impact the Company's overall credit risk, either positively or
negatively, in that these entities may be similarly affected by industry-wide
changes in economic or other conditions. Such receivables are generally not
collateralized. Historically, credit losses incurred by the Company on
receivables generally have not been material. No known material credit losses
were experienced during 1994.
 
(6) EMPLOYEE BENEFITS
 
     A total of 3,476,430 shares of Common Stock are reserved for issuance to
key employees and non-employee directors under the Company's stock option plans.
The stock option plans authorize the granting of options at prices equivalent to
the market value at the date of grant. Options generally become exercisable in
three annual installments commencing one year after the date granted and, if not
exercised, expire 10 years from the date of grant. At January 1, 1994, 1,490,676
shares were issuable under stock options outstanding. Options for 291,000 shares
were granted during 1994 at prices ranging from $19.13 to $22.25 per share.
During 1994, 376,639 options were exercised at prices ranging from $4.38 to
$17.44 per share and options to purchase 17,500 shares at a price of $16.25 were
cancelled. At December 31, 1994, options to purchase 1,387,537 shares were
outstanding (902,455 were exercisable) at prices ranging from $4.38 to $22.25.
 
     The Company has a tax-advantaged savings plan in which all salaried
employees may participate. Under such plan, a participating employee may
allocate up to 10% of his salary, and the Company makes matching contributions
of up to 6% thereof. Funds contributed by the employee and the matching funds
contributed by the Company are held in trust by a bank trustee in six separate
funds. Amounts contributed by the employee and earnings and accretions thereon
may be used to purchase shares of Common Stock, invest in a money market fund or
invest in four stock, bond, or blended stock and bond mutual funds according to
instructions from the employee. Matching funds contributed to the savings plan
by the Company are invested only in Common Stock. The Company contributed
$375,000 to the savings plan in 1994, $125,000 in 1993, and $288,000 in 1992.

     A trusteed retirement plan has been adopted by the Company for its salaried
employees. The benefits are based on years of service and the employee's average
compensation for five consecutive years within the final ten years of service
which produce the highest average compensation. The Company makes annual
contributions to the plan in the amount of retirement plan cost accrued or the
maximum amount which can be deducted for federal income tax purposes. The
following table sets forth the plan's funded status (in thousands of dollars) as
of December 31, 1994, 1993, and 1992.

     Effective January 1, 1992, the Company adopted the provisions of the
Statement of Financial Accounting Standards No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions." The Company currently provides
full medical benefits to its retired employees and dependents. For current
employees, the Company assumes all or a portion of postretirement medical and
term life insurance costs based on the employee's age and length of service with
the Company. The postretirement medical plan has no assets and is currently
funded by the Company on a pay-as-you-go basis.

     The following is an analysis (in thousands of dollars) of the annual
expense and activity in the deferred cost and benefits obligation accounts for
1992, 1993 and 1994. The computation assumes that future increases in medical
costs will trend down from 13% to 7% per year over the next 12 years for
purposes of estimating future costs. The medical cost trend rate assumption has
a significant effect on the amounts reported. Increasing the assumed medical
cost trend rate by one percent in each year would increase the aggregate of
service and interest cost components of net periodic postretirement benefit cost
for 1994 by $196,000 and the accumulated postretirement benefit obligation as of
December 31, 1994, by $897,000.

     The standardized measure of discounted future net cash flows from the
production of proved reserves is developed as follows:
 
          1. Estimates are made of quantities of proved reserves and the future
     periods in which they are expected to be produced based on year end
     economic conditions.
 
          2. The estimated future gross revenues from proved reserves are priced
     on the basis of year end prices, except in those instances where fixed and
     determinable natural gas price escalations are covered by contracts.

                                 (CONTINUED)
 
          3. The future gross revenue streams are reduced by estimated future
     costs to develop and to produce the proved reserves, as well as certain
     abandonment costs based on year end cost estimates, and the estimated
     effect of future income taxes. These cost estimates are subject to some
     uncertainty, particularly those estimates relating to the Company's
     properties located in the Kingdom of Thailand.
 
     The standardized measure of discounted future net cash flows does not
purport to present the fair market value of the Company's oil and gas reserves.
An estimate of fair value would also take into account, among other things, the
recovery of reserves in excess of proved reserves, anticipated future changes in
prices and costs, a discount factor more representative of the time value of
money and the risks inherent in reserve estimates.
 
     The following are the principal sources of change in the standardized
measure of discounted future net cash flows. All amounts are related to changes
in reserves located in the United States unless otherwise noted.

be embodied in and evidenced by one or more instruments of substantially
similar tenor signed by such Holders in person or by agent duly appointed in
writing; and, except as herein otherwise expressly provided, such action shall
become effective when such instrument or instruments are delivered to the
Trustee and, where it is hereby expressly required, to the Company.  Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments.  Proof of execution of any such instrument or
of a writing appointing any such agent shall be sufficient for any purpose of
this Indenture and (subject to Section 601) conclusive in favor of the Trustee
and the Company, if made in the manner provided in this Section.

          (b)  The fact and date of the execution by any Person of any such 
instrument or writing may be proved by the affidavit of a witness of such
execution or by a certificate of a notary public or other officer authorized by
law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof.  Where
such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other manner which the Trustee deems sufficient.

          (c)  The ownership of Securities shall be proved by the Security 
Register.

          (d)  Any request, demand, authorization, direction, notice, 
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and the Holder of every Security issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Trustee or
the Company in reliance thereon, whether or not notation of such action is made
upon such Security.

Section 105.   Notices, Etc., to Trustee and Company.

          Any request, demand, authorization, direction, notice, waiver or 
Act of Holders or other document provided or permitted  by this Indenture to be
made upon, given or furnished to, or filed with,
 
          (1)  the Trustee by any Holder or by the Company shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided)
     if made, given, furnished or filed in writing to or with the Trustee at
     its Corporate Trust Office, Attention:  Corporate Trust Administration
     Department, or
        
          (2)  the Company by the Trustee or by any Holder shall be sufficient
     for every purpose hereunder (unless otherwise herein expressly provided) 
     if in writing 
     

                                    - 9 -

     and mailed, first-class postage prepaid, to the Company addressed to it at
     the address of its principal office specified in the first paragraph of
     this instrument or at any other address previously furnished in writing to
     the Trustee by the Company.  If a notice or communication is mailed in the
     manner provided above, it is duly given, whether or not received by the
     addressee.
        
Section 106.   Notice to Holders; Waiver.

          Where this Indenture provides for notice to Holders of any event, 
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at his address as it appears in the Security Register,
not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice.  In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in
any notice so mailed, to any particular Holder shall affect the sufficiency of
such notice with respect to other Holders.  Where this Indenture provides for
notice in any manner, such notice may be waived in writing by the Person
entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice.  Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.  If
the Company mails a notice or communication to the Holders, it shall mail a
copy to the Trustee and each Registrar, Paying Agent or co-registrar.  If a
notice or communication is mailed in the manner provided above, it is duly
given, whether or not received by the addressee.

          In case by reason of the suspension of regular mail service or by 
reason of any other cause it shall be impracticable to give such notice by
mail, then such notification as shall be made with the approval of the Trustee
shall constitute a sufficient notification for every purpose hereunder.

Section 107.   Conflict with Trust Indenture Act.

          If any provision hereof limits, qualifies or conflicts with 
another provision hereof which is required to be included in this Indenture by
any of the provisions of the Trust Indenture Act, such required provision shall
control.  If any provision of this Indenture modifies or excludes any provision
of the Trust Indenture Act that may be so modified or excluded, the latter
provision shall be deemed to apply to this Indenture as so modified or to be
excluded, as the case may be.

Section 108.   Effect of Headings and Table of Contents.

          The Article and Section headings herein and the Table of Contents 
are for convenience only and shall not affect the construction hereof.

          In case any provision in this Indenture or in the Securities shall 
be invalid, illegal or unenforceable, the validity, legality and enforceability
of the remaining provisions shall not in any way be affected or impaired
thereby.

Section 111.   Benefits of Indenture.

          Nothing in this Indenture or in the Securities, express or 
implied, shall give to any Person, other than the parties hereto and their
successors hereunder, the holders of Senior Indebtedness and the Holders of
Securities, any benefit or any legal or equitable right, remedy or claim under
this Indenture.

construed in accordance with the laws of the State of New York, without regard

          In any case where any Interest Payment Date, Redemption Date or 
Stated Maturity of any Security or the last date on which a Holder has the
right to convert his Securities shall not be a Business Day, then
(notwithstanding any other provision of this Indenture or of the Securities)
payment of interest or principal (and premium, if any) or conversion of the
Securities need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the
Interest Payment Date or Redemption Date, or at the Stated Maturity, or on such
last day for conversion, provided that no interest shall accrue for the period
from and after such Interest Payment Date, Redemption Date or Stated Maturity,
as the case may be.

of Holders.  The Registrar and Paying Agent may make reasonable rules for their

          POGO PRODUCING COMPANY, a corporation duly organized and existing 
under the laws of Delaware (herein called the "Company", which term includes
any successor Person under the Indenture hereinafter referred to), for value
received, hereby promises to pay to ________________, or registered assigns,
the principal sum of ________________________ ___________________ Dollars on
March 15, 2004, and to pay interest thereon from March 23, 1994 or from the
most recent Interest Payment Date to which interest has been paid or duly
provided for, semiannually on March 15 and September 15, in each year,
commencing September 15, 1994, at the rate of 5 1/2% per annum until the 
principal hereof is paid or made available for payment.  Interest on the 
Securities shall be computed on the basis of a 360-day year consisting of 
twelve 30-day months. The interest so payable, and punctually paid or duly 
provided for, on any Interest Payment Date will, as provided in such Indenture,
be paid to the Person in whose name this Security (or one or more Predecessor 
Securities) is registered at the close of business on the Regular Record Date 
for such interest, which shall be the March 1st or September 1st (whether or 
not a Business Day), as the case may be, next preceding such Interest Payment 
Date.  Any such 


                                    - 12 -

interest not so punctually paid or duly provided for will forthwith cease to be
payable to the Holder on such Regular Record Date and may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities not less than 10 days prior to such Special
Record Date, or be paid at any time in any other lawful manner not inconsistent
with the requirements of any securities exchange on which the Securities may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in said Indenture.  Payment of the principal of (and premium, if
any) and interest on this Security will be made at the office or agency of the
Company maintained for that purpose in New York, New York, in such coin or
currency of the United States of America as at the time of payment is legal
tender for payment of public and private debts.  The Company, however, may pay
principal and interest by check payable in such money.  At the option of the
Company, payment of interest may be made by check mailed on or before the due
date to the address of the Person entitled thereto as such address shall appear
in the Security Register.

          Reference is hereby made to the further provisions of this 
Security set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.  The Indenture
includes limitations on the right of the Holder to institute a proceeding,
judicial or otherwise, with respect to the Indenture, for the appointment of a
receiver or trustee, or for any other remedy under the Indenture.

          Unless the certificate of authentication hereon has been executed 
by the Trustee referred to on the reverse hereof by manual signature, this
Security shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

          IN WITNESS WHEREOF, the Company has caused this instrument to be 
duly executed under its corporate seal.

Section 203.   Form of Reverse of Security.

          This Security is one of a duly authorized issue of Securities of 
the Company 
                               

                                    - 13 -

designated as its 5 1/2% Convertible Subordinated Notes due 2004 (herein called
the "Securities"), limited in aggregate principal amount to $75,000,000
(subject to increase to up to $86,250,000 aggregate principal amount), issued
and to be issued under an Indenture, dated as of March 23, 1994 (herein called
the "Indenture"), between the Company and Shawmut Bank Connecticut, National
Association, as Trustee (herein called the "Trustee", which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Company,
the Trustee, the holders of Senior Indebtedness and the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered.

          Subject to the provisions of the Indenture, the Holder hereof has 
the right, at his option, at any time prior to maturity, to convert the
principal amount of this Security (or any portion of the principal amount
hereof which is an integral multiple of $1,000) into fully paid and
nonassessable shares of Common Stock of the Company at the conversion price of
$22.188 of principal amount of this Security per share of Common Stock, subject
to such adjustment, if any, of the conversion price and the securities or other
property issuable upon conversion as may be required by the provisions of the
Indenture (except that, in case this Security (or any portion hereof) shall be
called for redemption before maturity, such right shall terminate at the close
of business on the Business Day immediately preceding the Redemption Date for
this Security (or such portion hereof), unless in any such case the Company
shall default in payment due upon such redemption), but only upon surrender of
this Security for the purpose of such conversion to the Company at the
designated office or agency of the Company in New York, New York or any other
office or agency designated by the Company for such purpose pursuant to the
provisions of the Indenture, accompanied by written notice that the Holder
elects to convert this Security or any portion hereof and specifying the name
or names (with address or addresses) in which a certificate or certificates for
shares of Common Stock are to be issued and (if so required by the Company or
the Trustee) by a written instrument or instruments of transfer in form
satisfactory to the Company and the Trustee duly executed by the registered
Holder or his duly authorized legal representative and transfer tax stamps or
funds therefor, if required pursuant to the provisions of the Indenture and, in
case such surrender shall be made during the period from the close of business
on any Regular Record Date to the opening of business on the next succeeding
Interest Payment Date (unless this Security or the portion thereof being
converted has been called for redemption), also accompanied by payment in funds
acceptable to the Company of an amount equal to the interest payable on such
Interest Payment Date on the principal amount of this Security then being
converted.  Subject to the aforesaid requirement with respect to payment in the
event of conversion after the close of business on a Regular Record Date, no
adjustment is to be made on conversion for interest accrued hereon or for
dividends on shares of Common Stock issued on conversion; provided, however,
that upon a call for redemption by the Company, accrued and unpaid interest to
the Redemption Date shall be payable with respect to Notes converted after the
redemption call and prior to the Redemption Date.  No fractional shares are
issuable upon any conversion, but in lieu thereof the Company shall pay
therefor in cash

as provided in the Indenture.

          The Securities are subject to redemption upon not less than 30 nor 
more than 60 days' notice by first-class mail, postage prepaid, at any time on
or after March 15, 1998, as a whole or in part, at the election of the Company,
at the following Redemption Prices (expressed as percentages of the principal
amount):  if redeemed during the 12-month period beginning March 15 of the
years indicated,

; provided, however, that in the case of any such redemption, the Redemption
Price shall include accrued and unpaid interest to the Redemption Date, but
interest installments whose Stated Maturity is on or prior to such Redemption
Date will be payable to the Holders of such Securities, or one or more
Predecessor Securities, of record at the close of business on the relevant
Record Dates referred to on the face hereof, all as provided in the Indenture.

          In the event of redemption or conversion of this Security in part 
only, a new Security or Securities for the unredeemed or unconverted portion
hereof will be issued in the name of the Holder hereof upon the cancellation
hereof.

          Under certain circumstances involving a Change in Control (as 
defined in the Indenture), the Company may be required to offer to purchase the
Securities at a purchase price equal to 100% of the principal amount thereof,
together with accrued and unpaid interest to the Repurchase Date.

          The indebtedness evidenced by the Securities is, to the extent and 
in the manner provided in the Indenture, expressly subordinate and subject in
right of payment to the prior payment in full of any Senior Indebtedness of the
Company or provision for such payment, whether outstanding at the date of the
Indenture or thereafter incurred, and this Security is issued subject to the
provisions of the Indenture with respect thereto.  Each Holder of this
Security, by his acceptance hereof, agrees to and shall be bound by such
provisions of the Indenture and authorizes and directs the Trustee in his
behalf to take such action as may be necessary or appropriate to effectuate 
such subordination and appoints the Trustee his attorney-in-fact for any and
all such purposes.

          If an Event of Default, as defined in the Indenture, shall occur 
and be continuing, the principal of all the Securities may be declared due and
payable in the manner and with the effect provided in the Indenture.
                               

                                    - 15 -
<PAGE>   25
          The Indenture permits, with certain exceptions as therein 
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Holders of the Securities
under the Indenture at any time by the Company and the Trustee with the consent
of the Holders of at least a majority in aggregate principal amount of the
Securities at the time Outstanding.  The Indenture also contains provisions
permitting the Holders of at least a majority in aggregate principal amount of
the Securities at the time Outstanding, on behalf of the Holders of all the
Securities, to waive compliance by the Company with certain provisions of the
Indenture and certain past defaults under the Indenture and their consequences. 
Any such consent or waiver by the Holder of this Security shall be conclusive
and binding upon such Holder and upon all future Holders of this Security and
of any Security issued upon the registration of transfer hereof or in exchange
herefor or in lieu hereof, whether or not notation of such consent or waiver is
made upon this Security.

          The Indenture provides that no Holder of any Security may enforce 
any remedy under the Indenture except in the case of failure of the Trustee to
act after notice of default and after request by the Holders of 25% in
aggregate principal amount of the Outstanding Securities and the offer and, if
requested, provision to the Trustee of reasonable indemnity satisfactory to the
Trustee; provided, however, that such provision shall not prevent the Holder
hereof from enforcing payment of the principal of (and premium, if any) or
interest on this Security after the same shall have become due.

          Initially, the Trustee will act as Paying Agent, Security 
Registrar and as the agent where notices and demands to or upon the Company in
respect of the Notes may be served.  The Company may appoint and change any
Paying Agent, Security Registrar or agent for notices without notice, other
than notice to the Trustee.  The Company or one of its subsidiaries may act as
Paying Agent, Security Registrar or agent for notices.

          No reference herein to the Indenture and no provision of this 
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, subject to the subordination
provisions, to pay the principal of (and premium, if any) and interest on this
Security at the times, place and rate, and in the coin or currency, herein
prescribed or to convert this Security as provided in the Indenture.

          As provided in the Indenture and subject to certain limitations 
therein set forth, the transfer of this Security is registrable in  the
Security Register, upon surrender of this Security for registration of transfer
at the office or agency of the Company in New York, New York, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar and duly executed by the Holder hereof or
his attorney duly authorized in writing, and thereupon one or more new
Securities, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees.

         The Securities are issuable only in registered form without coupons in
         

                         - 16 -
<PAGE>   26
denominations of $1,000 and any integral multiple thereof.  As provided in the
Indenture and subject to certain limitations therein set forth, Securities are
exchangeable for a like aggregate principal amount of Securities of a different
authorized denomination, as requested by the Holder surrendering the same.

          No service charge shall be made to the Holder for any such 
registration of transfer or exchange, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge payable in
connection therewith.

          Prior to due presentment of this Security for registration of 
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          This Security and the rights of the Holder hereof shall be 
governed by and construed in accordance with the laws of the State of New York
without regard to principles of conflicts of laws.

          All terms used in this Security which are defined in the Indenture 
shall have the meanings assigned to them in the Indenture.

or be valid or obligatory for any purpose unless there appears on such Security
a certificate of authentication substantially in the form provided for herein
executed by the Trustee by manual signature, and such certificate upon any
Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder.

Section 304.  Temporary Securities.

          Pending the preparation of definitive Securities, the Company may 
execute, and upon Company Order the Trustee shall authenticate and deliver,
temporary Securities which are printed, lithographed, typewritten, mimeographed
or otherwise produced, in any authorized denomination, substantially of the
tenor of the definitive Securities in lieu of which they are issued and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

          If temporary Securities are issued, the Company will cause 
definitive Securities to be prepared without unreasonable delay.  After the
preparation of definitive Securities, the temporary Securities shall be
exchangeable for definitive Securities upon surrender of the temporary
Securities at any office or agency of the Company designated pursuant to
Section 1002, without charge to the Holder.  Upon surrender for cancellation of
any one or more temporary Securities the Company shall execute and the Trustee
shall authenticate and deliver in exchange therefor a like principal amount of
definitive Securities of authorized denominations.  Until so exchanged the
temporary Securities shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities.

Section 305.  Registration, Registration of Transfer and Exchange.

          The Company shall cause to be kept at the Corporate Trust Office 
of the Trustee a register (the register maintained in such office and in any
other office or agency designated pursuant to Section 1002 being herein
sometimes collectively referred to as the "Security Register") in which,
subject to such reasonable regulations as it may prescribe, the Company shall
provide for the registration of Securities and of transfers of Securities.  The 


                                    - 21 -
<PAGE>   31
Trustee is hereby appointed "Security Registrar" for the purpose of 
registering Securities and transfers of Securities as herein provided.

          Upon surrender for registration of transfer of any Security at an 
office or agency of the Company designated pursuant to Section 1002 for such
purpose, the Company shall execute, and the Trustee shall authenticate and
deliver, in the name of the designated transferee or transferees, one or more
new Securities of any authorized denominations and of a like aggregate
principal amount.

          At the option of the Holder, Securities may be exchanged for other 
Securities of any authorized denominations and of a like aggregate principal
amount, upon surrender of the Securities to be exchanged at such office or
agency.  Whenever any Securities are so surrendered for exchange, the Company
shall execute, and the Trustee shall authenticate and deliver, the Securities
which the Holder making the exchange is entitled to receive.

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

          Every Security presented or surrendered for registration of 
transfer or for exchange shall (if so required by the Company or the Trustee)
be duly endorsed, or be accompanied by a written instrument of transfer in form
satisfactory to the Company and the Security Registrar duly executed, by the
Holder thereof or his attorney duly authorized in writing.

          No service charge shall be made to the Holder for any registration 
of transfer or exchange of Securities, but the Company may require payment of a
sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any registration of transfer or exchange of
Securities, other than exchanges pursuant to Section 304, 906, 1108, 1205 or
1301 not involving any transfer.

          Neither the Company nor the Trustee nor any agent of either shall 
be required (i) to issue, register the transfer of or exchange any Security
during a period beginning at the opening of business 15 days before the day of
the mailing of a notice of redemption of Securities selected for redemption
under Section 1104 and ending at the close of business on the day of such
mailing or (ii) to register the transfer of or exchange any Security so
selected for redemption in whole or in part, except the unredeemed portion of
any Security being redeemed in part.

Section 306.  Mutilated, Destroyed, Lost and Stolen Securities.

          If any mutilated Security is surrendered to the Trustee, the 
Company shall execute and the Trustee shall authenticate and deliver in
exchange therefor a new Security 

                                    - 22 -
<PAGE>   32
of like tenor and principal amount and bearing a number not contemporaneously 
outstanding.

          If there shall be delivered to the Company and the Trustee (i) 
evidence to their satisfaction of the destruction, loss or theft of any
Security and (ii) such security or indemnity as may be required by them to save
each of them and any agent of either of them harmless, then, in the absence of
actual notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company shall execute and upon a Company
Request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security, a new Security of like tenor and principal
amount and bearing a number not contemporaneously outstanding.

          In case any such mutilated, destroyed, lost or stolen Security has 
become or is about to become due and payable, the Company in its discretion
may, instead of issuing a new Security, pay such Security.

          Upon the issuance of any new Security under this Section, the 
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
reasonable expenses (including the expenses of the Trustee) connected
therewith.

          Every new Security issued pursuant to this Section in lieu of any 
mutilated, destroyed, lost or stolen Security shall constitute an original
additional contractual obligation of the Company, whether or not the mutilated,
destroyed, lost or stolen Security shall be at any time enforceable by anyone,
and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities duly issued hereunder.

          The provisions of this Section are exclusive and shall preclude (to 
the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

Section 307.  Payment of Interest; Interest Rights Preserved.

          Interest on any Security which is payable, and is punctually paid 
or duly provided for, on any Interest Payment Date shall be paid to the Person
in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest.

          Any interest on any Security which is payable, but is not 
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in clause (1) or (2) below:


                         - 23 -
<PAGE>   33
          (1)  The Company may elect to make payment of any Defaulted Interest 
     to the Persons in whose names the Securities (or their respective
     Predecessor Securities) are registered at the close of business on a
     Special Record Date for the payment of such Defaulted Interest, which
     shall be fixed in the following manner.  The Company shall notify the
     Trustee in writing of the amount of Defaulted Interest proposed to be paid
     on each Security and the date of the proposed payment, and at the same
     time the Company shall deposit with the Trustee an amount of money equal
     to the aggregate amount proposed to be paid in respect of such Defaulted
     Interest or shall make arrangements satisfactory to the Trustee for such
     deposit prior to the date of the proposed payment, such money when
     deposited to be held in trust for the benefit of the Persons entitled to
     such Defaulted Interest as in this clause provided.  Thereupon the Trustee
     shall fix a Special Record Date for the payment of such Defaulted Interest
     which shall be not more than 15 days and not less than 10 days prior to
     the date of the proposed payment and not less than 10 days after the
     receipt by the Trustee of the notice of the proposed payment.  The Trustee
     shall promptly notify the Company of such Special Record Date and, in the
     name and at the expense of the Company, shall cause notice of the proposed
     payment of such Defaulted Interest and the Special Record Date therefor to
     be mailed, first-class postage prepaid, to each Holder at his address as
     it appears in the Security Register, not less than 10 days prior to such
     Special Record Date.  Notice of the proposed payment of such Defaulted
     Interest and the Special Record Date therefor having been so mailed, such
     Defaulted Interest shall be paid to the Persons in whose names the
     Securities (or their respective Predecessor Securities) are registered at
     the close of business on such Special Record Date and shall no longer be
     payable pursuant to the following clause (2).
        
          (2)  The Company may make payment of any Defaulted Interest in any 
     other lawful manner not inconsistent with the requirements of any
     securities exchange on which the Securities may be listed, and upon such
     notice as may be required by such exchange, if, after notice given by the
     Company to the Trustee of the proposed payment pursuant to this clause,
     such manner of payment shall be deemed practicable by the Trustee.

          Subject to the foregoing provisions of this Section, each Security 
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

          In the case of any Security which is converted after any Regular 
Record Date and on or prior to the next succeeding Interest Payment Date (other
than any Security whose Maturity is prior to such Interest Payment Date),
interest whose Stated Maturity is on such Interest Payment Date shall be
payable on such Interest Payment Date notwithstanding such conversion, and such
interest (whether or not punctually paid or duly provided for) shall be paid to
the Person in whose name that Security (or one or more 
                               

                                    - 24 -
<PAGE>   34
Predecessor Securities) is registered at the close of business on such Regular
Record Date.  Upon a call for redemption by the Company, accrued and unpaid
interest to the Redemption Date shall be payable with respect to Securities
converted after the notice of redemption has been mailed and prior to the
Redemption Date.  Except as otherwise expressly provided in this paragraph, in
the case of any Security which is converted, interest whose Stated Maturity is
after the date of conversion of such Security shall not be payable.

Section 308.  Persons Deemed Owners.

          Prior to due presentment of a Security for registration of 
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Security is registered as the owner of
such Security for the purpose of receiving payment of and principal of (and
premium, if any) and (subject to Section 307) interest on such Security and for
all other purposes whatsoever, whether or not such Security be overdue, and
neither the Company, the Trustee nor any agent of the Company or the Trustee
shall be affected by notice to the contrary.

Section 309.  Cancellation.

          All Securities surrendered for payment, redemption, registration of 
transfer or exchange or conversion shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled
by it.  The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and all Securities so delivered
shall be promptly cancelled by the Trustee.  No Securities shall be
authenticated in lieu of or in exchange for any Securities cancelled as
provided in this Section, except as expressly permitted by this Indenture.  All
cancelled Securities held by the Trustee shall be disposed of as directed by a
Company Order.  The Company shall, within 120 days of a request therefor by the
Trustee, deliver a Company Order directing the destruction of cancelled
Securities.  If the Company fails to respond to such a request within such
120-day period, the Trustee may destroy any or all cancelled Securities, in
which case the Trustee shall deliver a certificate as to such destruction to
the Company.

Section 310.  Computation of Interest.

          Interest on the Securities shall be computed on the basis of a 
360-day year consisting of twelve 30-day months.

Section 401.  Satisfaction and Discharge of Indenture.

          This Indenture shall cease to be of further effect (except as to 
any surviving rights of conversion, registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, on demand of and at
the expense of the Company, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture, when

         (1)  either

              (A)  all Securities theretofore authenticated and delivered 
         (other than (i) Securities which have been destroyed, lost or stolen
         and which have been replaced or paid as provided in Section 306 and
         (ii) Securities for whose payment money has theretofore been
         deposited in trust or segregated and held in trust by the Company and
         thereafter repaid to the Company or discharged from such trust, as
         provided in Section 1003) have been delivered to the Trustee for
         cancellation; or

              (B)  all such Securities not theretofore delivered to the 
         Trustee for cancellation

                   (i)   have become due and payable, or

                   (ii)  will become due and payable at their Stated Maturity 
              within one year, or

                   (iii) are to be called for redemption within one year 
              under arrangements satisfactory to the Trustee for the giving of
              notice of redemption by the Trustee in the name, and at the
              expense, of the Company,

         and the Company, in the case of (i), (ii) or (iii) above, has
         irrevocably deposited or caused to be irrevocably deposited with the
         Trustee as trust funds in trust for the purpose an     amount
         sufficient to pay and discharge the entire indebtedness on such
         Securities not theretofore delivered to the Trustee for cancellation,
         for principal (and premium, if any) and interest to the date of such
         deposit (in the case of Securities which have become due and payable)
         or to the Stated Maturity or Redemption Date, as the case may be;

         (2)  the Company has paid or caused to be paid all other sums payable 
     hereunder by the Company; and

         (3)  the Company has delivered to the Trustee an Officers' Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     herein provided for relating to the satisfaction and discharge of this
     Indenture have been complied with.

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Section 607, the obligations of
the Trustee to any Authenticating Agent under Section 614 and, if money shall
have been deposited with the Trustee pursuant to subclause (B) of clause (1) of
this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

Section 402.  Application of Trust Money.

          Subject to the provisions of the last paragraph of Section 1003, 
all money deposited with the Trustee pursuant to Section 401 shall be held in
trust and applied by it, in accordance with the provisions of the Securities
and this Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal (and premium, if
any) and interest for whose payment such money has been deposited with the
Trustee.  All moneys deposited with the Trustee pursuant to Section 401 (and
held by it or any Paying Agent) for the payment of Securities subsequently
converted shall be returned to the Company upon Company Request.

Section 403.  Reinstatement.

          If the Trustee or Paying Agent is unable to apply any money 
deposited with respect to Securities of any series in accordance with Section
401 by reason of any legal proceeding or by reason of any order or judgment of
any court or governmental authority enjoining, restraining or otherwise
prohibiting such application, the Company's obligations under this Indenture
with respect to the Securities of such series and the Securities of such series
shall be revived and reinstated as though no deposit had occurred pursuant to
Section 401 until such time as the Trustee or Paying Agent is permitted to
apply all such money in accordance with Section 401; provided, however, that if
the Company has made any payment of principal of (or premium, if any) or
interest on any Securities because of the reinstatement of its obligations, the
Company shall be subrogated to the rights of the Holders of such Securities to
receive such payment from the money held by the Trustee or Paying Agent.

Section 501.  Events of Default.

          "Event of Default", wherever used herein, means any one of the 
following events (whatever the reason for such Event of Default and whether it
shall be occasioned by the provisions of Article Fourteen or be voluntary or
involuntary or be effected by operation of law or pursuant to any judgment,
decree or order of any court or any order, rule or regulation of any
administrative or governmental body):

         (1)  default in the payment of any interest upon any Security when it 
    becomes due and payable, whether or not such payment is prohibited by the   
    provisions of Article Fourteen, and continuance of such default for a
    period of 30 days; or

         (2)  default in the payment of the principal of (or premium, if any,

    Twelve, whether or not such payment is prohibited by the provisions of
    Article Fourteen; or

         (4)  default in the performance, or breach, of any covenant or 
    warranty of the Company in this Indenture (other than a covenant or
    warranty, a default in whose performance or whose breach is elsewhere in
    this Section specifically dealt with), and  continuance of such default or
    breach for a period of 60 days after there has been given, by registered or
    certified mail, to the Company by the Trustee or to the Company and the
    Trustee by the Holders of at least 25% in aggregate principal amount of the
    Outstanding Securities a written notice specifying such default or breach
    and requiring it to be remedied and stating that such notice is a "Notice
    of Default" hereunder; or

         (5)  default under any bond, debenture, note or other evidence of 
    indebtedness for money borrowed or under any mortgage, indenture or other

    any guarantee of payment by the Company of indebtedness for money borrowed,
    whether such indebtedness or guarantee now exists or shall hereafter be
    created, which default extends beyond any period of grace provided with
    respect thereto and which default relates to (a) the obligation to pay the
    principal of or interest on any such
    

                         - 28 -

    indebtedness or guarantee or (b) an obligation other than the obligation to
    pay the principal of or interest on any such indebtedness, if the effect of
    such event of default is to cause the acceleration of a principal amount of
    such indebtedness and such other indebtedness or guarantee shall not have
    been paid within ten days after there has been given to the Company
    by the Trustee or to the Company and the Trustee by the Holders of at least
    25% in aggregate principal amount of the Outstanding Securities a written
    notice specifying such event of default and stating that such notice is a
    "Notice of Default" hereunder; provided, however, that no default under
    this Section 501(5) shall exist if all such defaults do not relate to such
    indebtedness or such guarantees with an aggregate principal amount in
    excess of 5% of Consolidated Net Tangible Assets; and provided further,
    that if any such event of default has been cured or waived and any
    acceleration with respect thereto rescinded, or if such other indebtedness
    has been repaid or otherwise discharged, the Event of Default arising under
    this Section 501(5) by virtue thereof shall not be deemed to have occurred
    and any acceleration under this Section 501(5) pursuant to Section 502
    hereof shall ipso facto be rescinded so long as such rescission does not
    conflict with any judgment or decree;

         (6)  the entry by a court having jurisdiction in the premises of (a) 
    a decree or order for relief in respect of the Company in an involuntary
    case or proceeding under any applicable federal or state bankruptcy,

    adjudging the Company a bankrupt or insolvent, or approving as properly

    substantial part of its property, or ordering the winding up or liquidation
    of its affairs, and the continuance of any such decree or order for relief

    of a decree or order for relief in respect of the Company in an involuntary
    case or proceeding under any applicable federal or state bankruptcy,
    insolvency, reorganization or other similar law or to the commencement of
    any bankruptcy or insolvency case or proceeding against it, or the filing
    by it of a petition or answer or consent seeking reorganization or relief

    making by it of an assignment for the benefit of creditors, or the

    they become due, or the taking of corporate action by the Company in
    furtherance of any

    such action.

Section 502.  Acceleration of Maturity; Rescission and Annulment.

          If an Event of Default occurs and is continuing, then and in every 
such case the Trustee or the Holders of not less than 25% in aggregate
principal amount of the Outstanding Securities may declare the principal of all
the Securities and the interest accrued thereon to be due and payable
immediately, by a notice in writing to the Company (and to the Trustee if given
by Holders) and upon any such declaration such principal and interest shall
become immediately due and payable.

          At any time after such a declaration of acceleration has been made 
and before a judgment or decree for payment of the money due has been obtained
by the Trustee as hereinafter in this Article provided, the Holders of a
majority in aggregate principal amount of the Outstanding Securities, by
written notice to the Company and the Trustee, may rescind and annul such
declaration and its consequences if

         (1)  the Company has paid or deposited with the Trustee
    a sum sufficient to pay

              (A)  all overdue interest on all Securities,

              (B)  the principal of (and premium, if any, on) any Securities 
         which have become due otherwise than by such declaration of   
         acceleration and interest thereon at the rate borne by the Securities,

              (C)  to the extent that payment of such interest is lawful, 
         interest upon overdue interest at the rate borne by the Securities, and

              (D)  all sums paid or advanced or liabilities incurred by the 
         Trustee hereunder and the reasonable compensation, expenses, 
         disbursements and advances of the Trustee, its agents and counsel;

         and

         (2)  all Events of Default, other than the nonpayment of the principal
    of Securities which have become due solely by such declaration of 
    acceleration, have been cured or waived as provided in Section 513.

No such rescission shall affect any subsequent default or impair any right
consequent thereon.

Section 503.  Collection of Indebtedness and Suits for Enforcement by Trustee.

         The Company covenants that if

         (1)  default is made in the payment of any interest on any Security 
    when such interest becomes due and payable and such default continues for a 
    period of 30 days, or

         (2)  default is made in the payment of the principal of (or premium, 
    if any, on) any Security at the Maturity thereof,

the Company will, upon demand of the Trustee, pay to it, for the benefit of the
Holders of such Securities, the whole amount then due and payable on such
Securities for principal (and premium, if any) and interest, and, to the extent
that payment of such interest shall be legally enforceable, interest on any
overdue principal (and premium, if any) and on any overdue interest, at the
rate borne by the Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the costs and expenses of collection, including
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel.

          If the Company fails to pay such amounts forthwith upon such 
demand, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the sums so due and
unpaid, may prosecute such proceeding to judgment or final decree and may
enforce the same against the Company or any other obligor upon the Securities
and collect the moneys adjudged or decreed to be payable in the manner provided
by law out of the property of the Company or any other obligor upon the
Securities, wherever situated.

          If an Event of Default occurs and is continuing, the Trustee may in 
its discretion proceed to protect and enforce its rights and the rights of the
Holders by such appropriate judicial proceedings as the Trustee, being advised
by counsel, shall deem most effectual to protect and enforce any such rights,
whether for the specific enforcement of any covenant or agreement in this
Indenture or in aid of the exercise of any power granted herein, or to enforce
any other proper remedy.

Section 504.  Trustee May File Proofs of Claim.

          In case of the pendency of any receivership, insolvency, 
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition
or other judicial proceeding relative to the Company or any other obligor upon
the Securities or the property of the Company or of such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of overdue principal or interest) shall be entitled 


                                    - 31 -
<PAGE>   41
and empowered, by intervention in such proceeding or otherwise,

         (i)  to file and prove a claim for the whole amount of principal (and
    premium, if any) and interest owing and unpaid in respect of the
    Securities, subject to the provisions of Article Fourteen, and to file such
    other papers or documents as may be necessary or advisable in order to have
    the claims of the Trustee (including any claim for the reasonable
    compensation, expenses, disbursements and advances of the Trustee, its
    agents and counsel) and of the Holders allowed in such judicial proceeding,
    subject to the provisions of Article Fourteen, and

         (ii) subject to the provisions of Article Fourteen, to collect and 
    receive any moneys or other property payable or deliverable on any such 
    claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders,
to pay to the Trustee any amount due it for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel,
and any other amounts due the Trustee under Section 607.

          Nothing herein contained shall be deemed to authorize the Trustee 
to authorize or consent to or accept or adopt on behalf of any Holder any plan
of reorganization, arrangement, adjustment or composition affecting the
Securities or the rights of any Holder thereof or to authorize the Trustee to
vote in respect of the claim of any Holder in any such proceeding.

Section 505.  Trustee May Enforce Claims Without Possession of Securities.

          All rights of action and claims under this Indenture or the 
Securities may be prosecuted and enforced by the Trustee without the possession
of any of the Securities or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment
shall, after provision for the payment of the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities in respect of which
such judgment has been recovered.  In any such proceeding brought by the
Trustee, the Trustee shall be deemed to represent all Holders without the
necessity of joining any Holders as parties.

Section 506.  Application of Money Collected.

          Subject to Article Fourteen, any money collected by the Trustee 
pursuant to this Article shall be applied in the following order, at the date
or dates fixed by the Trustee and, in the case of the distribution of such
money on account of principal (or premium, if 


                                    - 32 -
<PAGE>   42

of the payment if only partially paid and upon surrender thereof if fully paid:

         FIRST:  To the payment of all costs and expenses in connection with 
    the collection of such money and to the payment of all amounts due the 
    Trustee under Section 607; and

         SECOND:  To the payment of the amounts then due and unpaid for  
    principal of (and premium, if any) and interest on the Securities in 
    respect of which or for the benefit of which such money has been collected,

    amounts due and payable on such Securities for principal (and premium, if 
    any) and interest, respectively.

Section 507.  Limitation on Suits.

          No Holder of any Security shall have any right to institute any 
proceeding, judicial or otherwise, with respect to this Indenture or for the
appointment of a receiver or trustee or for any other remedy hereunder, unless

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

         (2)  the Holders of not less than 25% in aggregate principal amount of
    the Outstanding Securities shall have made written request to the Trustee
    to institute proceedings in respect of such Event of Default in its own 
    name as Trustee hereunder;

         (3)  such Holder or Holders offer and, if requested, provide to the 
    Trustee indemnity satisfactory to the Trustee against the costs, expenses
    and liabilities to be incurred in compliance with such request;

         (4)  the Trustee for 60 days after its receipt of such notice, request
    and offer and, if requested, provision of indemnity has failed to 
    institute any such proceeding; and

         (5)  no direction inconsistent with such written request has been 
    given to the Trustee during such 60-day period by the Holders of a majority
    in aggregate principal amount of the Outstanding Securities;

it being understood and intended that no one or more Holders shall have any
right in any manner whatever by virtue of, or by availing of, any provision of
this Indenture to affect, disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain priority or preference over any other Holders
or to enforce any right under this Indenture, except in the manner herein
provided and for the equal and ratable benefit of all the


                                    - 33 -

Holders.

Section 508.  Unconditional Right of Holders to Receive Principal, Premium and 
              Interest and to Convert.

          Notwithstanding any other provision in this Indenture, the Holder 
of any Security shall have the right, which is absolute and unconditional,
subject to the subordination provisions in Article Fourteen, to receive payment
of the principal of (and premium, if any) and (subject to Section 307) interest
on such Security on the respective Stated Maturities expressed in such Security
(or, in the case of redemption, on the Redemption Date) and to institute suit
for the enforcement of any such payment, and such rights shall not be impaired
without the consent of such Holder.

Section 509.  Restoration of Rights and Remedies.

          If the Trustee or any Holder has instituted any proceeding to 
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders
shall be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

Section 510.  Rights and Remedies Cumulative.

          Except as otherwise provided with respect to the replacement or 
payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved
to the Trustee or to the Holders is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent
the concurrent assertion or employment of any other appropriate right or
remedy.

Section 511.  Delay or Omission Not Waiver.

          No delay or omission of the Trustee or of any Holder of any 
Security to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event
of Default or an acquiescence therein.  Every right and remedy given by this
Article or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee or by the
Holders, as the case may be.

Section 512.  Control by Holders.

          The Holders of a majority in aggregate principal amount of the 
Outstanding Securities shall have the right to direct in writing 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, provided
that

         (1)  such direction shall not be in conflict with any rule of law or 
    with this Indenture,

         (2)  the Trustee may take any other action deemed proper by the 
    Trustee which is not inconsistent with such direction, and

         (3)  subject to the provisions of Section 601, the Trustee shall have
    the right to decline to follow any such direction if the Trustee in good 
    faith shall determine that the action so directed would involve the Trustee
    in personal liability or would be unduly prejudicial to Holders not joining
    in such direction.

          This Section 512 shall be in lieu of Section 316(a)(1)(A) of the 
Trust Indenture Act and said Section 316(a)(1)(A) is hereby expressly excluded
from this Indenture, as permitted by the Trust Indenture Act.

Section 513.  Waiver of Past Defaults.

          The Holders of not less than a majority in aggregate principal 
amount of the Outstanding Securities may on behalf of the Holders of all the
Securities waive any past default hereunder and its consequences, except a
default

         (1)  in the payment of the principal of (or premium, if any) or 
    interest on any Security, or

         (2)  in respect of a covenant or provision hereof which under Article
    Nine cannot be modified or amended without the consent of the Holder of 
    each Outstanding Security affected.

         Upon any such waiver, such default shall cease to exist, and any 
Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture; but no such waiver shall extend to any
subsequent or other default or impair any right consequent thereon.  This
Section 513 shall be in lieu of Section 316(a)(1)(B) of the Trust Indenture Act
and said Section 316(a)(1)(B) is hereby expressly excluded from this Indenture,
as permitted by the Trust Indenture Act.

Section 514.  Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security 
by his acceptance thereof shall be deemed to have agreed, that any court may in
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit, having due regard to the merits
and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding more than 10% in aggregate principal
amount of the Outstanding Securities, or to any suit instituted by any Holder
for the enforcement of the payment of the principal of (or premium, if any) or
interest on any Security on or after the respective Stated Maturities expressed
in such Security (or, in the case of redemption, on or after the Redemption
Date) or for the enforcement of the right to convert any Security in accordance
with Article Thirteen.  This Section 514 shall be in lieu of Section 315(e) of
the Trust Indenture Act and said Section 315(e) is hereby expressly excluded
from this Indenture, as permitted by the Trust Indenture Act.

Section 515.  Waiver of Stay or Extension Laws.

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

Section 601.  Certain Duties and Responsibilities.

         The duties and responsibilities of the Trustee shall be as provided 
by the Trust Indenture Act.  Notwithstanding the foregoing, no provision of
this Indenture shall require the Trustee to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it. 
Whether or not 


                                    - 36 -
<PAGE>   46
therein expressly so provided, every provision of this Indenture relating to

Trustee shall be subject to the provisions of this Section.

Section 602.  Notice of Defaults.

         The Trustee shall give the Holders notice of any default hereunder 
as and to the extent provided by the Trust Indenture Act; provided, however,
that in the case of any default of the character specified in Section 501(4),
no such notice to Holders shall be given until at least 30 days after the
occurrence thereof.  For the purpose of this Section, the term "default" means
any event which is, or after notice or lapse of time or both would become, an
Event of Default.

Section 603.  Certain Rights of Trustee.

         Subject to the provisions of Section 601:

         (a)  the Trustee may rely and shall be protected in acting or

    shall deem it desirable that a matter be proved or established prior to

    other evidence be herein specifically prescribed) may, in the absence of
    bad faith on its part, rely upon an Officers' Certificate;
        
         (d)  the Trustee may consult with counsel and the written advice of 
    such counsel or any Opinion of Counsel shall be full and complete
    authorization and protection in respect of any action taken, suffered or
    omitted by it hereunder in good faith and in reliance thereon;
        
         (e)  the Trustee shall be under no obligation to exercise any of the 
    rights or powers vested in it by this Indenture at the request, order or
    direction of any of the Holders pursuant to this Indenture, unless such
    Holders shall have offered to the Trustee security or indemnity
    satisfactory to the Trustee against the costs, expenses and liabilities
    which might be incurred by it in compliance with such request or direction;
        

                                    - 37 -
<PAGE>   47
         (f)  the Trustee shall not be bound to make any investigation into the
    facts or matters stated in any resolution, certificate, statement,
    instrument, opinion, report, notice, request, direction, consent, order,
    bond, debenture, note, other evidence of indebtedness or other paper or
    document, but the Trustee, in its discretion, may make such further inquiry
    or investigation into such facts or matters as it may see fit, and, if the
    Trustee shall determine to make such further inquiry or investigation, it
    shall be entitled to examine the books, records and premises of the Company
    personally or by agent or attorney; and
        
         (g)  the Trustee may execute any of the trusts or powers hereunder or
    perform any duties hereunder either directly or by or through agents or
    attorneys, and the Trustee shall not be responsible for any misconduct or
    negligence on the part of any agent or attorney appointed with due care by
    it hereunder.
        
Section 604.  Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the 
Trustee's certificates of authentication, shall be taken as the statements of
the Company, and the Trustee assumes no responsibility for their correctness.

Securities or the proceeds thereof.

Security Registrar or any other agent of the Company, in its individual or any
other capacity, may become the owner or pledgee of Securities and, subject to
Sections 608 and 613, may otherwise deal with the Company with the same rights
it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent.

Section 606.  Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated 
from other funds except to the extent required by law.  The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company.

Section 607.  Compensation and Reimbursement.

         The Company agrees

         (1)  to pay to the Trustee from time to time reasonable compensation 
    for all services rendered by it hereunder (which compensation shall not be 
    limited by any 


                                    - 38 -
<PAGE>   48
    provision of law in regard to the compensation of a trustee of an express
    trust);

         (2)  except as otherwise expressly provided herein, to reimburse the 
    Trustee upon its request for all reasonable expenses, disbursements and
    advances incurred or made by the Trustee in accordance with any provision
    of this Indenture (including the reasonable compensation and the expenses
    and disbursements of its agents and counsel), except any such expense,
    disbursement or advance as may be attributable to its negligence or bad
    faith; and
        
         (3)  to indemnify the Trustee, its agents, employees, officers, 
    directors and shareholders for, and to hold each of them harmless against,
    any loss, liability or expense incurred without negligence or bad faith on
    its part, arising out of or in connection with the acceptance or
    administration of this trust, including the costs and expenses of defending
    itself against any claim or liability in connection with the exercise or
    performance of any of its powers or duties hereunder.
        
         As security for the performance of the obligations of the Company 
under this Section the Trustee shall have a lien prior to the Securities upon
all property and funds held or collected by the Trustee as such, except funds
held in trust for the payment of principal of, premium, if any, or interest on
particular Securities.

         When the Trustee incurs expenses or renders services after an Event 
of Default specified in Section 501(6) or (7) occurs, the expenses (including
the reasonable charges and expenses of its agents, attorneys and counsel) and
the compensation for services shall be preferred over the status of the Holders
in any reorganization or similar proceeding and are intended to constitute
expenses of administration under any reorganization, bankruptcy or similar law.

Section 608.  Disqualification; Conflicting Interests.

         If the Trustee has or shall acquire a conflicting interest within 
the meaning of the Trust Indenture Act, the Trustee shall either eliminate such
interest or resign, to the extent and in the manner provided by, and subject to
the provisions of, the Trust Indenture Act and this Indenture.

Section 609.  Corporate Trustee Required; Eligibility.

         There shall at all times be a Trustee hereunder which shall be a 
Person that is eligible pursuant to the Trust Indenture Act to act as such, has
an office or agency in New York, New York, and has a combined capital and

If such corporation or other Person publishes reports of condition at least
annually, pursuant to law or to the requirements of said supervising or
examining authority, then for the purposes of this Section, the combined

                                    - 39 -
<PAGE>   49
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published.  If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this
Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.  No obligor upon any Securities issued
under this Indenture or Person directly or indirectly controlling, controlled
by or under common control with such obligor shall serve as Trustee under this
Indenture.

Section 610.  Resignation and Removal; Appointment of Successor.

         (a)  No resignation or removal of the Trustee and no appointment of 
a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 611.

         (b)  The Trustee may resign at any time by giving written notice 
thereof to the Company.  If an instrument of acceptance by a successor Trustee
shall not have been delivered to the Trustee within 30 days after the giving of
such notice of resignation, the resigning Trustee may petition any court of
competent jurisdiction for the appointment of a successor Trustee.

         (c)  The Trustee may be removed at any time by Act of the Holders of 
a majority in aggregate principal amount of the Outstanding Securities
specifying such removal, delivered to the Trustee and to the Company.

         (d)  If at any time:

              (1)  the Trustee shall fail to comply with Section 608 after 
         written request therefor by the Company or by any Holder who has been
         a bona fide Holder of a Security for at least six months, or

              (2)  the Trustee shall cease to be eligible under Section 609 and
         shall fail to resign after written request therefor by the Company or
         by any such bona fide Holder described in (d)(1) above, or

              (3)  the Trustee shall become incapable of acting or shall be 
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of 
         its property shall be appointed or any public officer shall take 
         charge or control of the Trustee or of its property or affairs for 
         the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Trustee, or (ii) subject to Section 514, any Holder who has been a bona fide
Holder of a Security for at least six months may, on behalf of himself and all
others similarly situated, petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.
      

                                    - 40 -
<PAGE>   50
         (e)  If the Trustee shall resign, be removed or become incapable of 
acting, or if a vacancy shall occur in the office of Trustee for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee. 
If, within one year after such resignation, removal or incapability, or the
occurrence of such vacancy, a successor Trustee shall be appointed by Act of
the Holders of a majority in aggregate principal amount of the Outstanding
Securities delivered to the Company and the retiring Trustee, the successor
Trustee so appointed shall, forthwith upon its acceptance of such appointment,
become the successor Trustee and supersede the successor Trustee appointed by
the Company.  If no successor Trustee shall have been so appointed by the
Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Security for at least
six months may, on behalf of himself and all others similarly situated,
petition any court of competent jurisdiction for the appointment of a successor
Trustee.

         (f)  The Company shall give notice of each resignation and each 
removal of the Trustee and each appointment of a successor Trustee by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders as their names and addresses appear in the Security Register.  Each
notice shall include the name of the successor Trustee and the address of its
Corporate Trust Office.

Section 611.  Acceptance of Appointment by Successor.

         Every successor Trustee appointed hereunder shall execute, 
acknowledge and deliver to the Company and to the retiring Trustee an
instrument accepting such appointment, and thereupon the resignation or removal
of the retiring Trustee shall become effective and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the
rights, powers, trusts and duties of the retiring Trustee; but, on request of
the Company or the successor Trustee, such retiring Trustee shall, upon payment
of its charges, execute and deliver an instrument transferring to such
successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property
and money held by such retiring Trustee hereunder.  Upon request of any such
successor Trustee, the Company shall execute any and all instruments for more
fully and certainly vesting in and confirming to such successor Trustee all
such rights, powers and trusts.

         No successor Trustee shall accept its appointment unless at the time 
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.

Section 612.  Merger, Conversion, Consolidation or Succession to Business.

with which it may be consolidated, or any corporation resulting from any
merger, conversion or consolidation to which the Trustee shall be a party, or
any corporation succeeding to all or substantially all the corporate trust
business of the Trustee, shall be the successor of the

Trustee hereunder, provided such corporation shall be otherwise qualified and
eligible under this Article, without the execution or filing of any paper or
any further act on the part of any of the parties hereto.  In case any
Securities shall have been authenticated, but not delivered, by the Trustee
then in office, any successor by merger, conversion or consolidation to such
authenticating Trustee may adopt such authentication and deliver the Securities
so authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities.

Section 613.  Preferential Collection of Claims Against Company.

         If and when the Trustee shall be or become a creditor of the Company 
(or any other obligor upon the Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims
against the Company (or any such other obligor).

Section 614.  Appointment of Authenticating Agent.

         The Trustee may appoint an Authenticating Agent or Agents which 
shall be authorized to act on behalf of the Trustee to authenticate Securities
issued upon original issue and upon exchange, registration of transfer, partial
conversion or partial redemption or pursuant to Section 306, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder.  Wherever reference is made in this Indenture to the authentication
and delivery of Securities by the Trustee or the Trustee's certificate of
authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent and a certificate
of authentication executed on behalf of the Trustee by an Authenticating Agent. 
Each Authenticating Agent shall be acceptable to the Company and shall at all
times be a corporation organized and doing business under the laws of the
United States of America, any state thereof or the District of Columbia,
authorized under such laws to act as Authenticating Agent, having a combined
capital and surplus of not less than $50,000,000 (or being a member or
subsidiary of a bank holding system with aggregate combined capital and surplus
of at least $50,000,000) and subject to supervision or examination by federal
or state authority.  If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the
combined capital and surplus of such Authenticating Agent shall be deemed to be
its combined capital and surplus as set forth in its most recent report of
condition so published.  If at any time an Authenticating Agent shall cease to
be eligible in accordance with the provisions of this Section, such
Authenticating Agent shall resign immediately in the manner and with the effect
specified in this Section.

         Any corporation into which an Authenticating Agent may be merged or 
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, 


                                    - 42 -
<PAGE>   52
or any corporation succeeding to the corporate agency or corporate trust
business of an Authenticating Agent, shall continue to be an Authenticating
Agent, provided such corporation shall be otherwise eligible under this
Section, without the execution or filing of any paper or any further act on the
part of the Trustee or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving 30 days' 
written notice thereof to the Trustee and to the Company.  The Trustee may at
any time terminate the agency of an Authenticating Agent by giving 30 days'
written notice thereof to such Authenticating Agent and to the Company.  Upon
receiving such a notice of resignation or upon such a termination, or in case
at any time such Authenticating Agent shall cease to be eligible in accordance
with the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall mail
written notice of such appointment by first- class mail, postage prepaid, to
all Holders as their names and addresses appear in the Security Register.  Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent. 
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

         The Trustee agrees to pay to each Authenticating Agent from time to 
time reasonable compensation for its services under this Section, and the
Trustee shall be entitled to be reimbursed for such payments, subject to the
provisions of Section 607.

         If an appointment is made pursuant to this Section, the Securities 
may have endorsed thereon, in addition to the Trustee's certificate of
authentication, an alternate certificate of authentication in the following
form:

         This is one of the Securities described in the within-mentioned 
Indenture.

Section 902.  Supplemental Indentures With Consent of Holders.  

         With the consent of the Holders of not less than a majority in
aggregate principal amount of the Outstanding Securities, by Act of said
Holders delivered to the Company and the Trustee, the Company, when authorized
by a Board Resolution, and the Trustee may enter into an indenture or
indentures supplemental hereto for the purpose of adding any provisions to or
changing in any manner or eliminating any of the provisions of this Indenture
or of modifying in any manner the rights of the Holders under this Indenture;
provided, however, that no such supplemental indenture shall, without the
consent of the Holder of each Outstanding Security affected thereby,

    installment of interest on, any Security, or reduce the principal amount
    thereof or the rate of interest thereon or any premium payable upon the

    redemption, on or after the Redemption Date), or adversely affect the right
    to convert any Security as provided in Article Thirteen (except as
    permitted by Section 901(3)), or
        
         (2)  reduce the percentage in principal amount of the Outstanding

    Holder of each Outstanding Security affected thereby.

         It shall not be necessary for any Act of Holders under this Section 
to approve the particular form of any proposed supplemental Indenture, but it
shall be sufficient if such Act shall approve the substance thereof.

         The Company may, but shall not be obligated to, fix a record date 
for the purpose of determining the Holders entitled to consent to any indenture
supplemental hereto.  If a record date is fixed, then those persons who were
Holders at such record date (or their duly designated proxies), and only those
persons, shall be entitled to consent to such supplemental Indenture or to

Holders after such record date.  No such consent shall be valid or effective
for more than 90 days after such record date.

Section 903.  Execution of Supplemental Indentures.

         In executing, or accepting any additional trusts created by, any 
supplemental indenture permitted by this  Article or the modifications thereby

receive, and (subject to Section 601) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such supplemental indenture

Section 1001.  Payment of Principal, Premium and Interest.

         The Company will duly and punctually pay the principal of (and 
premium, if any) and interest on the Securities in accordance with the terms of
the Securities and this Indenture.

Section 1002.  Maintenance of Office or Agency.

         The Company will maintain in New York, New York an office or agency 
where Securities may be presented or surrendered for payment, where Securities
may be surrendered for registration of transfer or exchange, where Securities
may be surrendered for conversion and where notices and demands to or upon the
Company in respect of the Securities and this Indenture may be served.  The
Company initially designates the office of the Trustee at Shawmut Bank, c/o
First Chicago, 14 Wall Street, 8th Floor -- Window No. 2, New York, New York
10005, as its office or agency for these purposes.  The Company will give
prompt written notice to the Trustee of the location, and any change in the
location, of such office or agency.  If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the
Trustee with the address thereof, such presentations, surrenders, notices and
demands may be made or served at the Corporate Trust Office of the Trustee, and
the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

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

Section 1003.  Money for Security Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent, it 
will, on or before each due date of the  principal of (and premium, if any) or
interest on any of the Securities, segregate and hold in trust for the benefit
of the Persons entitled thereto a sum sufficient to pay the principal (and
premium, if any) or interest so becoming due until such 
                                                                              

                                    - 49 -
<PAGE>   59
sums shall be paid to such Persons or otherwise disposed of as herein provided
and will promptly notify the Trustee of its action or failure so to  act. 

         Whenever the Company shall have one or more Paying Agents, it will, 
prior to each due date of the principal of (and premium, if any) or interest on
any Securities, deposit in immediately available funds with a Paying Agent a
sum sufficient to pay the principal (and premium, if any) or interest so
becoming due, such sum to be held in trust for the benefit of the Persons
entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Company will promptly notify the Trustee of its action or
failure so to act.

         The Company will cause each Paying Agent other than the Trustee to 
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will:

         (1)   comply with the provisions of the Trust Indenture Act applicable
    to it as a Paying Agent; and

         (2)   at any time during the continuance of any default, upon the 
    written request of the Trustee, forthwith pay to the Trustee all sums so 
    held in trust by such Paying Agent.

         The Company may at any time, for the purpose of obtaining the 
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held
in trust by the Company or such Paying Agent, such sums to be held by the
Trustee upon the same trusts as those upon which such sums were held by the
Company or such Paying Agent; and, upon such payment by any Paying Agent to the
Trustee, such Paying Agent shall be released from all further liability with
respect to such money.

         Any money deposited with the Trustee or any Paying Agent, or then 
held by the Company, in trust for the payment of the principal of (and premium,
if any) or interest on any Security and remaining unclaimed for two years (or
such shorter period as required by applicable abandonment law with respect to
the Holder entitled to payment thereof) after such principal (and premium, if
any) or interest has become due and payable shall be paid to the Company on
Company Request, or (if then held by the Company) shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured
general creditor, look only to the Company for payment thereof, unless an
applicable abandonment statute designates another Person, and all liability of
the Trustee or such Paying Agent with respect to such trust money, and all
liability of the Company as trustee thereof, shall thereupon cease; provided,
however, that the Trustee or such Paying Agent, before being required to make
any such repayment, may at the expense of the Company cause to be published
once, in a newspaper published in the English language, customarily published
on each Business Day and of general circulation in New York, New York, notice 


                                    - 50 -

that such money remains unclaimed and that, after a date specified therein,
which shall not be less than 30 days from the date of such publication, any
unclaimed balance of such money then remaining will be repaid to the Company.

Section 1004.  Existence.

         Subject to Article Eight, the Company will do or cause to be done 
all things necessary to preserve and keep in full force and effect its
existence, rights (charter and statutory) and franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if a transaction that would result in the termination of the Company's
existence or any such right or franchise is permissible under Article Eight or
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and that the
loss thereof is not disadvantageous in any material respect to the Holders.

Section 1005.  Statement by Officers as to Default.

         The Company will deliver to the Trustee, within 120 days after the 
end of each fiscal year of the Company, in each case ending after the date
hereof, an Officers' Certificate, stating that a review of the activities of
the Company during the preceding fiscal year has been made under the
supervision of the signing officers with a view to determining whether the
Company has kept, observed, performed and fulfilled its obligations under this
Indenture, and further stating, as to each such officer signing such
certificate, that to the best of his knowledge the Company is not in default in
the performance or observance of any of the terms, provisions and conditions
hereof or, if a default or Event of Default shall have occurred, describing all
such defaults or Events of Default of which he may have knowledge and that to
the best of his knowledge no event has occurred and remains in existence by
reason of which payments on account of the principal of or interest, if any, on
the Securities are prohibited or if such event has occurred, a description of
the event.

Section 1006.  Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any 
covenant or condition set forth in Section 1004, if before the time for such
compliance the Holders of at least a majority in aggregate principal amount of
the Outstanding Securities shall, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver

Trustee in respect of any such covenant or condition shall remain in full force
and effect.

                           REDEMPTION OF SECURITIES

Section 1101.  Right of Redemption.

         The Securities may be redeemed at the election of the Company, as a 
whole or from time to time in part, at any time on or after March 15, 1998, at
the Redemption Prices specified in the form of Security hereinbefore set forth,
together with accrued interest to the Redemption Date.

Section 1102.  Applicability of Article.

         Redemption of Securities at the election of the Company or 
otherwise, as permitted or required by any provision of this Indenture, shall
be made in accordance with such provision and this Article.

Section 1103.  Election to Redeem; Notice to Trustee.

         The election of the Company to redeem any Securities pursuant to 
Section 1101 shall be evidenced by a Board Resolution.  In case of any
redemption at the election of the Company of less than all the Securities, the
Company shall, at least 45 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities
to be redeemed and whether the Trustee is to give the notice of redemption.

Section 1104.  Selection by Trustee of Securities to Be Redeemed.

         If less than all the Securities are to be redeemed pursuant to 
Section 1101, the particular Securities to be redeemed shall be selected not
more than 45 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities not previously called for redemption, by such method
(including pro rata or by lot) as the Trustee shall deem fair and appropriate
and which may provide for the selection for redemption of portions (equal to
$1,000 or any integral multiple thereof) of the principal amount of Securities
of a denomination larger than $1,000.

         If any Security selected for partial redemption is converted in part 
before termination of the conversion right with respect to the portion of the
Security so selected, the converted portion of such Security shall be deemed
(so far as may be) to be the portion selected for redemption.  Securities which
have been converted during a selection of Securities to be redeemed shall be
treated by the Trustee as Outstanding for the purpose of such selection.
                               

                                    - 52 -
<PAGE>   62
         The Trustee shall promptly notify the Company and each Security 
Registrar in writing of the Securities selected for redemption and, in the case
of any Securities selected for partial redemption, the principal amount thereof
to be redeemed.

         For all purposes of this Indenture, unless the context otherwise 
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Securities redeemed or to be redeemed only in part, to the
portion of the principal amount of such Securities which has been or is to be
redeemed.

Section 1105.  Notice of Redemption.

         Notice of redemption shall be given by first-class mail, postage 
prepaid, mailed not less than 30 nor more than 60 days prior to the Redemption
Date, to each Holder of Securities to be redeemed, at his address appearing in
the Security Register.

         All notices of redemption shall state:

         (1)   the Redemption Date;

         (2)   the Redemption Price;

         (3)   if less than all the Outstanding Securities are to be redeemed,
    the identification (and, in the case of partial redemption, the principal 
    amounts) of the particular Securities to be redeemed;

         (4)   that on the Redemption Date the Redemption Price will become due
    and payable upon each such Security to be redeemed and that interest 
    thereon will cease to accrue on and after said date;

         (5)   the conversion price, the date on which the right to convert 
    the principal of the Securities to be redeemed will terminate and the 
    place or places where such Securities may be surrendered for conversion; and

         (6)   the place or places where such Securities are to be surrendered
    for payment of the Redemption Price.

         Notice of redemption of Securities to be redeemed at the election of 
the Company shall be given by the Company or, at Company Request, by the
Trustee in the name and at the expense of the Company.

Section 1106.  Deposit of Redemption Price.

         Prior to any Redemption Date, the Company shall deposit with the 
Trustee or with a Paying Agent (or, if the  Company is acting as its own Paying
Agent, segregate and 


                                    - 53 -

hold in trust as provided in Section 1003) an amount of money in immediately
available funds sufficient to pay the Redemption Price of, and (except if the
Redemption Date shall be an Interest Payment Date) accrued interest on, all the
Securities which are to be redeemed on that date other than any Securities
called for redemption on that date which have been converted prior to the date
of such deposit.

         If any Security called for redemption is converted, any money 
deposited with the Trustee or with any Paying Agent or so segregated and held
in trust for the redemption of such Security shall (subject to the right of the
Holder of such Security or any Predecessor Security to receive interest as
provided in the last paragraph of Section 307) be paid to the Company upon
Company Request or, if then held by the Company, shall be discharged from such
trust.

Section 1107.  Securities Payable on Redemption Date.

         Notice of redemption having been given as aforesaid, the Securities 
so to be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest) such Securities shall cease to bear interest.  Upon surrender of any
such Security for redemption in accordance with said notice, such Security
shall be paid by the Company at the Redemption Price, together with accrued
interest to the Redemption Date; provided, however, that installments of
interest whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

         If any Security called for redemption shall not be so paid upon 
surrender thereof for redemption, the principal (and premium, if any) shall,
until paid, bear interest from the Redemption Date at the rate borne by the
Security.

Section 1108.  Securities Redeemed in Part.

         Any Security which is to be redeemed only in part shall be 
surrendered at an office or agency of the Company designated for that purpose
pursuant to Section 1002 (with, if the Company or Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Security or Securities, of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered.

                         RIGHT TO REQUIRE REPURCHASE

Section 1201.  Right to Require Repurchase.

         In the event that there shall occur a Change in Control (as defined 
in Section 1206) which constitutes a Repurchase Event (as defined in Section
1206), then each Holder shall have the right, at such Holder's option to
require the Company to purchase, and upon the exercise of such right, the
Company shall, subject to the provisions of Article Fourteen, purchase all or
any part of such Holder's Securities on a date (the "Repurchase Date") selected
by the Company that is not more than 75 days after the date the Company gives
notice of the Repurchase Event as contemplated in Section 1202(a) at a price
(the "Repurchase Price") equal to 100% of the principal amount thereof,
together with accrued and unpaid interest to the Repurchase Date.

Section 1202.  Notice; Method of Exercising Repurchase Right.

         (a)   On or before the 15th day after the Repurchase Event, the 
Company, or at Company Request, the Trustee (in the name and at the expense of
the Company), shall give notice of the occurrence of the Repurchase Event and
of the repurchase right set forth herein arising as a result thereof by
first-class mail, postage prepaid, to each Holder of the Securities at such
Holder's address appearing in the Security Register.  The Company shall also
deliver a copy of such notice of a repurchase right to the Trustee.

         Each notice of a repurchase right shall state:

               (1) the event constituting the Repurchase Event and the date 
                   thereof,

               (2) the Repurchase Date,

               (3) the date by which the repurchase right must be exercised,

               (4) the Repurchase Price, and

               (5) the instructions a Holder must follow to exercise a 
                   repurchase right.

         No failure of the Company to give the foregoing notice shall limit 
any Holder's right to exercise a repurchase right.  The Trustee shall have no
affirmative obligation to determine if there shall have occurred a Repurchase
Event.

         (b)   To exercise a repurchase right, a Holder shall deliver to the 
Company


                                    - 55 -
<PAGE>   65
(or an agent designated by the Company for such purpose in the notice referred
to in (a) above) and to the Trustee on or before the close of business on the
Business Day immediately preceding the Repurchase Date (i) written notice of
the Holder's exercise of such right, which notice shall set forth the name of
the Holder, the principal amount of the Security or Securities (or portion of a
Security) to be repurchased, and a statement that an election to exercise the
repurchased right is being made thereby, and (ii) the Security or Securities
with respect to which the repurchase right is being exercised, duly endorsed
for transfer to the Company.  Such written notice shall be irrevocable.  If the
Repurchase Date falls between any Regular Record Date and the next succeeding
Interest Payment Date, Securities to be repurchased must be accompanied by
payment from the Holder of an amount equal to the interest thereon which the
registered Holder thereof is to receive on such Interest Payment Date.

         (c)   In the event a repurchase right shall be exercised in 
accordance with the terms hereof, then subject to Article Fourteen, the Company
shall on or promptly following the Repurchase Date pay or cause to be paid in
cash to the Holder thereof the Repurchase Price of the Security or Securities
as to which the repurchase right had been exercised.  In the event that a
repurchase right is exercised with respect to less than the entire principal
amount of a surrendered Security, the Company shall execute and deliver to the
Trustee and the Trustee shall authenticate for issuance in the name of the
Holder a new Security or Securities in the aggregate principal amount of the
unrepurchased portion of such surrendered security.

Section 1203.  Deposit of Repurchase Price.

         On or prior to the Repurchase Date and subject to Article Fourteen, 
the Company shall deposit with the Trustee or with a Paying Agent (or, if the
Company is acting as its own Paying Agent, segregate and hold in trust as
provided in Section 1003) an amount of money, in immediately available funds,
sufficient to pay the Repurchase Price of the Securities which are to be repaid
on or promptly following the Repurchase Date.

Section 1204.  Securities Not Repurchased on Repurchase Date.

         If any Security surrendered for repurchase shall not be paid by the 
10th day following the Repurchase Date, the principal shall, until paid, bear
interest to the extent permitted by applicable law from the eleventh day
following the Repurchase Date at a rate per annum borne by such Security.

Section 1205.  Securities Repurchased in Part.

         Any Security which is to be repurchased only in part shall be 
surrendered at any office or agency of the Company designated for that purpose
pursuant to Section 1002 (with, if the Company or the Trustee so requires, due
endorsement by, or written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the 


                                    - 56 -
<PAGE>   66
Holder thereof or his attorney duly authorized in writing), and the Company 
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of any
authorized denomination as requested by such Holder, in aggregate principal
amount equal to and in exchange for the repurchased portion of the principal of
the Security so surrendered.

Section 1206.  "Change in Control" and "Repurchase Event" Defined.

         (a)   For purposes of this Article, "Change in Control" means any of 
the following events that occurs after the Issue Date of the Securities and so
long as any Securities are Outstanding:

               (1) the Company's assets are sold or otherwise disposed of 
         substantially as an entirety to any Person or related group of 
         Persons in any one transaction or a series of related transactions;

               (2) 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 number of shares of common
         stock of such Subsidiary) or (B) pursuant to which the Common Stock is
         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
         consolidation or merger; or
        
               (3) any Person, or any Persons acting together which would 
         constitute a "group" for purposes of Section 13(d) of the Exchange Act
         (a "Group") (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, which may file or become obligated
         to file a report under or in response to Schedule 13D or Schedule
         14D-1 (or any successor schedule, form or report) under the Exchange
         Act), together with any Affiliates thereof, shall acquire beneficial
         ownership (as defined in Rule 13d-3 of the Exchange Act) of at least
         50% of the total voting power of all classes of capital stock of the
         Company entitled to vote generally in the election of directors of the
         Company.

         (b)   A Change in Control as described in Section 1206(a) shall 
constitute a "Repurchase Event" giving rise to a repurchase right on the part
of each Holder of a Security unless:

               (1) the Current Market Price of the Common Stock on the date the
         Change in Control shall have occurred is at least equal to 105% of the
         conversion price in effect immediately preceding the time of such 
         Change in Control, or

               (2) all of the consideration (excluding cash payments for 

         fractional shares) in the transaction giving rise to such Change in
         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
         System, and as a result of such transaction the Securities become
         convertible solely into such shares of common stock, or
        
               (3) the consideration in the transaction giving rise to such 
         Change in 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
         System, or a combination of cash and such securities and the aggregate
         fair market value of such consideration (which, in the case of each
         such security, shall be equal to the average of the daily Closing
         Prices of each such security during the 10 consecutive Trading Days
         commencing with the sixth Trading Day following consummation of such
         transaction) to be received by a holder of Common Stock with respect
         to one share of Common Stock is at least 105% of the conversion price
         in effect on the date immediately preceding the closing date of such
         transaction.
        
         For purposes of this definition, "Current Market Price" on any date 
means the average daily Closing Prices for the 5 consecutive Trading Days
selected by the Company commencing not more than 10 Trading Days before, and
ending not later than, the date in question.

                           CONVERSION OF SECURITIES

Section 1301.  Right of Conversion.

         The Holder of any Security or Securities shall have the right at any 
time prior to maturity, at his option, to convert, subject to the terms and
provisions of this Article 


                                    - 58 -
<PAGE>   68
Thirteen, the principal of any such Security or Securities (or any portion of
the principal thereof which is $1,000 or an integral multiple of $1,000) into
fully paid and nonassessable shares of Common Stock of the Company at the
conversion price of $22.188 of principal amount of Securities per share of
Common Stock or, in case an adjustment therein has taken place pursuant to the
provisions of Section 1304, then at the price as so adjusted (except that with
respect to any Security or Securities, or any such portion, which shall be
called for redemption, such right shall terminate, except as provided in the
last paragraph of Section 1302, at the close of business on the Business Day
immediately preceding the Redemption Date for such Security or Securities or
portion unless the Company shall default in payment due upon redemption
thereof).  Such right shall be exercised by the surrender of the Security or
Securities, the principal of which is so to be converted, to the Company at any
time during usual business hours at any office or agency to be maintained by it
in accordance with the provisions of Section 1002, accompanied by written
notice that the Holder elects to convert such Security or Securities or any
portion thereof and specifying the name or names (with address) in which a
certificate or certificates for Common Stock are to be issued and (if so
required by the Company or the Trustee) by a written instrument or instruments
of transfer in form satisfactory to the Company and the Trustee, duly executed
by the Holder or his attorney, duly authorized in writing and transfer tax
stamps or funds therefor, if required pursuant to Section 1310.  For
convenience, the conversion of all or a portion, as the case may be, of the
principal of any Security into the Common Stock of the Company is hereinafter
sometimes referred to as the conversion of such Security.  All Securities
surrendered for conversion shall, if surrendered to the Company or any
conversion agent, be delivered to the Trustee for cancellation and cancelled by
it or, if surrendered to the Trustee, shall be cancelled by it; and, subject to
the next succeeding sentence, no Securities shall be issued in lieu thereof. 
In the case of any Security which is converted in part only, upon such
conversion the Company shall execute and the Trustee shall authenticate and
deliver to the Holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations in an aggregate principal amount equal
to the unconverted portion of the principal amount of such Security.

Section 1302.  Issuance of Common Stock; Time of Conversion.

         As promptly as practicable after the surrender, as herein provided, 
of any Security or Securities for conversion, the Company shall deliver or
cause to be delivered at any office or agency to be maintained by it in
accordance with the provisions of Section 1002 to or upon the written order of
the Holder of the Security or Securities so surrendered a certificate or
certificates representing the number of fully paid and nonassessable shares of
Common Stock of the Company into which such Security or Securities (or portion
thereof) may be converted in accordance with the provisions of this Article
Thirteen.  Subject to the following provisions of this paragraph and of Section
1304, such conversion shall be deemed to have been made immediately prior to
the close of business on the date that such Security or Securities shall have
been surrendered in satisfactory form for conversion, so that the rights of the
Holder as a Holder shall cease with respect to such Security or Securities (or
the portion thereof being converted) at such time, and the Person or Persons
entitled to 


                                    - 59 -
<PAGE>   69
receive the shares of Common Stock deliverable upon conversion of such Security
or Securities shall be treated for all purposes as having become the record
holder or holders of such shares of Common Stock at such time, and such
conversion shall be at the conversion price in effect at such time; provided,
however, that no such surrender on any date when the stock transfer books of
the Company shall be closed shall be effective to constitute the Person or
Persons entitled to receive the shares of Common Stock deliverable upon such
conversion as the record holder or holders of such shares of Common Stock on
such date, but such surrender shall be effective to constitute the Person or
Persons entitled to receive such shares of Common Stock as the record holder or
holders thereof for all purposes immediately prior to the close of business on
the next succeeding day on which such stock transfer books are open, and such
conversion shall be deemed to have been made at, and shall be made at the
conversion rate in effect at, such time on such next succeeding day.

         If the last day for the exercise of the conversion right shall not 
be a Business Day, then such conversion right may be exercised on the next
succeeding Business Day.

Section 1303.  No Adjustments in Respect of Interest or Dividends.

         Securities surrendered for conversion during the period from the 
close of business on any Regular Record Date to the opening of business on the
next succeeding Interest Payment Date shall (except in the case of Securities
or portions thereof which have been called for redemption) be accompanied by
payment in New York Clearing House funds or other funds acceptable to the
Company of an amount equal to the interest payable on such Interest Payment
Date on the principal amount of Securities being surrendered for conversion. 
Upon a call for redemption by the Company, accrued and unpaid interest to the
Redemption Date shall be payable with respect to Securities converted after the
redemption notice has been mailed and prior to the Redemption Date.  Except as
provided in this Section 1303 and subject to the last paragraph of Section 307,
no payment or adjustment shall be made upon any conversion on account of any
interest accrued on the Securities surrendered for conversion or on account of
any dividends on the shares of Common Stock issued upon conversion.

Section 1304.  Adjustment of Conversion Price.

         The conversion price, and consequently the number of shares of 
Common Stock into which a Security is convertible, shall be subject to
adjustment from time to time as follows:

         (a)   In case the Company shall (i) pay a dividend on Common Stock or
    make a distribution on its Common Stock that is paid or made (1) in shares
    of any class of capital stock of the Company or (2) in rights to purchase 
    any stock or other securities if such rights are not separable from the 
    Common Stock except upon the occurrence of a contingency, (ii) subdivide 
    its outstanding shares of Common Stock 
    

                                    - 60 -
<PAGE>   70
    into a greater number of shares or (iii) combine its outstanding shares of
    Common Stock into a smaller number of shares, then in each such case the
    conversion price in effect immediately prior thereto shall be adjusted
    retroactively as provided below so that the Holder of any Security
    thereafter surrendered for conversion shall be entitled to receive the
    number of shares of Common Stock and other shares and rights to purchase
    stock or other securities (or, in the event of the redemption of any such
    shares or rights, any cash, property or securities paid in respect of such
    redemption) which such Holder would have owned or have been entitled to
    receive after the happening of any of the events described above had such
    Security been converted immediately prior to the happening of such event. 
    An adjustment made pursuant to this Subsection (a) shall become effective
    immediately after the record date in the case of a dividend or distribution
    and shall become effective immediately after the effective date in the case
    of a subdivision or combination.
        
         (b)   In case the Company shall issue rights or warrants to all 
    holders of its Common Stock entitling them (for a period expiring within 45
    days after the date fixed for determination mentioned below) to subscribe
    for or purchase shares of Common Stock at a price per share less than the
    current market price per share (determined as provided in paragraph (d) of
    this Section) of the Common Stock on the date fixed for the determination
    of stockholders entitled to receive such rights or warrants, then the
    conversion price in effect at the opening of business on the day following
    the date fixed for such determination shall be decreased by multiplying
    such conversion price by a fraction of which the denominator shall be the
    number of shares of Common Stock outstanding at the close of business on
    the date fixed for such determination plus the number of shares of Common
    Stock so offered for subscription or purchase, and the numerator shall be
    the number of shares of Common Stock outstanding at the close of business
    on the date fixed for such determination plus the number of shares of
    Common Stock which the aggregate of the offering price of the total number
    of shares of Common Stock so offered for subscription or purchase would
    purchase at such current market price, such reduction to become effective
    immediately after the opening of business on the day following the date
    fixed for such determination; provided, however, in the event that all the
    shares of Common Stock offered for subscription or purchase are not
    delivered upon the exercise of such rights or warrants, upon the expiration
    of such rights or warrants the conversion price shall be readjusted to the
    conversion price which would have been in effect had the numerator and the
    denominator of the foregoing fraction and the resulting adjustment been
    made based upon the number of shares of Common Stock actually delivered
    upon the exercise of such rights or warrants rather than upon the number of
    shares of Common Stock offered for subscription or purchase.  For the
    purposes of this paragraph (b), the number of shares of Common Stock at any
    time outstanding shall not include shares held in the treasury of the
    Company.
        
         (c)   In case the Company shall, by dividend or otherwise, distribute
    to substantially all holders of its Common Stock evidences of its 
    indebtedness, cash 
    

                                    - 61 -

    (excluding quarterly cash dividends paid or to be paid on a regular basis),
    other assets or rights or warrants to subscribe for or purchase any
    securities (excluding those referred to in paragraphs (a) and (b) above),
    then in each such case, the conversion price shall be adjusted
    retroactively so that the same shall equal the price determined by
    multiplying the conversion price in effect immediately prior to the close
    of business on the date fixed for the determination of stockholders
    entitled to receive such distribution by a fraction of which the
    denominator shall be the current market price per share (determined as
    provided in paragraph (d) of this Section) of the Common Stock on the date
    fixed for such determination and the numerator shall be such current market
    price per share of the Common Stock less the amount of cash and the then
    fair market value (as determined by the Board of Directors, whose
    determination shall be conclusive and described in a Board Resolution filed
    with the Trustee) of the portion of the assets, rights, warrants or
    evidences of indebtedness so distributed applicable to one share of Common
    Stock, such adjustment to become effective immediately prior to the opening
    of business on the day following the date fixed for the determination of
    stockholders entitled to receive such distribution.
        
         (d)   For the purpose of any computation under paragraphs (b) and (c)
    of this Section, the current market price per share of Common Stock on any
    date shall be deemed to be the average of the daily closing prices for the
    30 consecutive trading days commencing with the 45th trading day before the
    day in question.  The closing price for each day shall be the last reported
    sales price regular way or, in case no such reported sale takes place on
    such day, the average of the reported closing bid and asked prices regular
    way, in either case on the composite tape of the principal national
    securities exchange upon which the Common Stock is listed or on the NASDAQ
    National Market System (based on the aggregate dollar value of all
    securities listed or admitted to trading) or, if the Common Stock is not
    listed or admitted to trading on any national securities exchange or quoted
    on the NASDAQ National Market System, the average of the closing bid and
    asked prices in the over-the-counter market as furnished by any New York
    Stock Exchange member firm selected from time to time by the Company for
    that purpose, or, if such prices are not available, the fair market value
    set by, or in a manner established by, the Board of Directors of the
    Company in good faith.  "Trading day" shall mean a day on which the
    national securities exchange or the NASDAQ National Market System used to
    determine the closing price is open for the transaction of business or the
    reporting of trades or, if the closing price is not so determined, a day on
    which the New York Stock Exchange is open for the transaction of business.
        
         (e)   No adjustment in the conversion price shall be required unless 
    such adjustment would require an increase or decrease of at least 1% in
    such price; provided, however, that the Company may make any such
    adjustment at its election; and provided, further, that any adjustments
    which by reason of this paragraph (e) are not required to be made shall be
    carried forward and taken into account in any subsequent adjustment.  All
    calculations  under this Article Thirteen shall be made to the nearest cent
    or 
        

                                    - 62 -
<PAGE>   72
    to the nearest one-hundredth of a share, as the case may be.

         (f)   Whenever the conversion price is adjusted as provided in any 
    provision of this Article Thirteen:

               (i) the Company shall compute the adjusted conversion price in 
         accordance with paragraph (d) and shall prepare a certificate signed
         by the principal financial officer of the Company setting forth the
         adjusted conversion price and showing in reasonable detail the facts
         and calculations upon which such adjustment is based, and such
         certificate shall forthwith be filed with the Trustee and at each
         office or agency maintained for the purpose of conversion of
         Securities; and
        
               (ii)     a notice stating that the conversion price has been 
         adjusted and setting forth the adjusted conversion price shall
         forthwith be required, and as soon as practicable after it is
         required, such notice shall be mailed by the Company to all Holders at
         their last addresses as they shall appear in the Security Register.
        
         (g)  In the event that at any time, as a result of any adjustment made
    pursuant to this Article Thirteen, the Holder of any Security thereafter
    surrendered for conversion shall become entitled to receive any shares of
    the Company other than shares of Common Stock or to receive any other
    securities, the number of such other shares or securities so receivable
    upon conversion of any Security shall be subject to adjustment from time to
    time in a manner and on terms as nearly equivalent as practicable to the
    provisions contained in this Article Thirteen with respect to the Common
    Stock.
        
         (h)   The Company from time to time may, by Board Resolution delivered
    to the Trustee, decrease the conversion price by any amount for any period
    of time if the period is at least 20 days and if the decrease is
    irrevocable during the period.  Whenever the conversion price is so
    decreased, the Company shall mail to the Holders a notice of the decrease
    at least 15 days before the date the decreased conversion price takes
    effect, and such notice shall state the decreased conversion price and the
    period it will be in effect.
        
         (i)   The Company may make such decreases in the conversion price, in
    addition to those required or allowed by this Article Thirteen, as shall be
    determined by it, as evidenced by a Board Resolution delivered to the
    Trustee, to be advisable in order to avoid or diminish any income tax to
    holders of Common Stock resulting from any dividend or distribution of
    stock or issuance of rights or warrants to purchase or subscribe for stock
    or from any event treated as such for income tax purposes.

<PAGE>   73
         (j)   In any case in which this Section 1304 provides that an 
    adjustment shall become effective immediately after a record date for an
    event, the Company may defer until the occurrence of such event (i) issuing
    to the holder of any Security converted after such record date and before
    the occurrence of such event the additional shares of Common Stock issuable
    upon such conversion by reason of the adjustment required by such event
    over and above the Common Stock issuable upon such conversion before giving
    effect to such adjustment and (ii) paying to such holder any amount in cash
    in lieu of any fraction pursuant to Section 1305.
        
Section 1305.  No Fractional Shares.

         No fractional shares or scrip representing fractional shares of 
Common Stock shall be issued upon conversion of Securities.  If more than one
Security shall be surrendered for conversion at one time by the same Holder,
the number of full shares issuable upon conversion thereof shall be computed on
the basis of the aggregate principal amount of the Securities (or specified
portions thereof) so surrendered.  Instead of any fractional share of Common
Stock which would otherwise be issuable upon conversion of any Security or
Securities (or specified portions thereof), the Company shall pay a cash
adjustment in respect of such fraction in an amount equal to the same fraction
of the closing price per share of Common Stock as quoted on the composite tape
of the principal national securities exchange upon which the Common Stock is
listed or the NASDAQ National Market System or, in case no such reported sale
takes place on such day, the average of the reported closing bid and asked
prices regular way, in either case on the NASDAQ National Market System or, if
the Common Stock is not listed or admitted to trading on any national
securities exchange or quoted on the NASDAQ National Market System, the average
of the closing bid and asked prices in the over-the-counter market as furnished
by any New York Stock Exchange member firm selected from time to time by the
Company for that purpose, or, if such prices are not available, the fair market
value set by, or in a manner established by, the Board of Directors of the
Company in good faith, all of the above to be determined as of the close of
business on the day of conversion.

Section 1306.  Reclassification, Consolidation, Merger or Sale of Assets.

         In case of any reclassification of the Common Stock, any 
consolidation of the Company with, or merger of  the Company into, any other
Person, any merger of another Person into the Company (other than a merger
which does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock of the Company), any sale or
other disposition of the assets of the Company substantially as an entirety or
any compulsory share exchange pursuant to which share exchange the Common Stock
is converted into other securities, cash or other property, then the Holder of
each Security then outstanding shall have the right thereafter, during the
period such Security shall be convertible, pursuant to Section 1301, to convert
such Security only into the kind and amount of securities, cash and other
property receivable upon such reclassification, consolidation, merger, sale,
other disposition or share exchange by a holder of the number 
                               

                         - 64 -
<PAGE>   74
of shares of Common Stock of the Company into which such Security might have
been converted immediately prior to such reclassification, consolidation,
merger, sale, other disposition or share exchange assuming such holder of
Common Stock (i) is not a Person with which the Company consolidated or into
which the Company merged or which merged into the Company, to which such sale
or other disposition was made or a party to such share exchange, as the case
may be ("constituent Person"), or an Affiliate of a constituent Person and (ii)
failed to exercise his rights of election, if any, as to the kind or  amount of
securities, cash and other property receivable upon such  reclassification,
consolidation, merger, sale, other disposition or share  exchange (provided
that if the kind or amount of securities, cash and other  property receivable
upon such reclassification, consolidation, merger, sale,  other disposition or
share exchange is not the same for each share of Common  Stock held immediately
prior to such reclassification, consolidation, merger,  sale, other disposition
or share exchange by others than a constituent Person  or an Affiliate thereof
and in respect of which such rights of election shall  not have been exercised
("non-electing share"), then for the purpose of this Article the kind and
amount of securities, cash and other property receivable upon such
reclassification, consolidation, merger, sale, other disposition or share
exchange by each non-electing share shall be deemed to be the kind and amount
so receivable per share by a plurality of the non-electing shares).  The
Company or the Person formed by such consolidation or resulting from such
merger or which acquires such assets or which acquires the Company's shares, as
the case may be, shall execute and deliver to the Trustee a supplemental
indenture to establish such right.  Such supplemental indenture shall provide
for adjustments which, for events subsequent to the effective date of such
supplemental indenture, shall be as nearly equivalent as may be practicable to
the adjustments provided for in this Article.  The above provisions of this
Section shall similarly apply to successive reclassifications, consolidations,
mergers, sales, other dispositions or share exchanges.

         Notice of the execution of such a supplemental indenture shall be 
given by the Company to each Holder by mailing such notice to his last address
appearing on the Security Register.

         Neither the Trustee nor any conversion agent shall be under any 
responsibility to determine the correctness of any provisions contained in any
such supplemental indenture relating either to the kind or amount of shares of
stock or securities or cash or property receivable by Holders of Securities
upon the conversion of their Securities after any such reclassification,
change, consolidation, merger, sale or other disposition or to any such
adjustment, but, subject to the provisions of Section 601, may accept as
conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, an Opinion of Counsel with respect thereto, which
the Company shall cause to be furnished to the Trustee upon request.

Section 1307.  Prior Notice of Certain Events.

         In case:

         (a)   the Company shall (i) declare any dividend (or any other 
    distribution) on its Common Stock other than (1) a dividend payable in
    shares of Common Stock or (2) a quarterly cash dividend paid or to be paid
    on a regular basis or (ii) declare or authorize a redemption or repurchase
    of in excess of 10% of the then outstanding shares of Common Stock; or
        
         (b)   the Company shall authorize the granting to the holders of its 
    Common Stock of rights or warrants to subscribe for or purchase any shares
    of stock of any class or of any other rights or warrants; or
        
         (c)   of any reclassification of the Common Stock of the Company 
    (other than a subdivision or combination of its outstanding Common Stock,
    or a change in par value, or from par value to no par value, or from no par
    value to par value), or of any consolidation or merger to which the Company
    is a party and for which approval of any stockholders of the Company is
    required, or of the sale or other disposition of the assets of the Company
    substantially as an entirety or of any compulsory share exchange whereby
    the Common Stock is converted into other securities, cash or other
    property; or
         
         (d)   of the voluntary or involuntary dissolution, liquidation or 
    winding up of the Company;

then the Company shall cause to be filed with the Trustee and to be mailed to
each Holder of Securities at his last address appearing on the Security
Register, as promptly as possible but in any event at least 15 days prior to
the applicable date hereinafter specified, a notice stating (x) the date on
which a record is to be taken for the purpose of such dividend, distribution or
granting of rights or warrants or, if a record is not to be taken, the date as
of which the holders of Common Stock of record to be entitled to such dividend,
distribution, rights or warrants are to be determined, or (y) the date on which
such reclassification, consolidation, merger, sale, other disposition, share
exchange, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected that holders of Common Stock
of record shall be entitled to exchange their shares of Common Stock for
securities or other property deliverable upon such reclassification,
consolidation, merger, sale, other disposition, share exchange, dissolution,
liquidation or winding up.

Section 1308.  Shares to be Reserved; Accounting Treatment of Consideration.

         The Company covenants that it will at all times reserve and keep 
available out of its authorized but unissued Common Stock, free from preemptive
rights solely for the 


                                    - 66 -
<PAGE>   76
purpose of issue upon conversion of Securities as herein provided, such number 
of shares of Common Stock as shall then be issuable upon the conversion of all 
outstanding Securities. The Company covenants that all shares of Common Stock 
which shall be so issuable shall, when issued, be duly and validly issued and 
fully paid and nonassessable.

         The Company covenants that, upon conversion of Securities as herein 
provided, there will be credited to the Common Stock capital account from the
consideration for which the shares of Common Stock issuable upon such
conversion are issued an amount per share of Common Stock so issued as
determined by the Board of Directors, which amount shall not be less than the
amount required by law and by the Company's certificate of incorporation, as
amended, as in effect on the date of such conversion.  For the purposes of this
covenant the principal amount of the Securities converted, less any cash paid
in respect of fractional share interests upon such conversion, shall be deemed
to be the amount of consideration for which the shares of Common Stock issuable
upon such conversion are issued.

Section 1309.  Registration and Listing of Shares.

         The Company covenants that if any shares of Common Stock required to 
be reserved for purposes of conversion of  Securities hereunder require
registration with or approval of any governmental authority under any federal
or state law before such shares may be issued upon conversion, the Company will
in good faith and as expeditiously as possible endeavor to cause such shares to
be duly registered or approved, as the case may be.  The Company further
covenants that so long as the Common Stock of the Company is listed on any
national securities exchange or on the NASDAQ National Market System, the
Company will, if permitted by the rules thereof, list and keep listed thereon,
upon official notice of issuance, all shares of Common Stock issuable upon
conversion of Securities.

Section 1310.  Taxes and Charges.

         The issuance of certificates for shares of Common Stock upon the 
conversion of Securities shall be made without charge to the converting Holder
of Securities for such certificates or for any tax in respect of the issuance
of such certificates or the securities represented thereby, and such
certificates shall be issued in the respective names of, or in such names as
may be directed by, the Holders of the Securities converted; provided, however,
that the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the issuance and delivery of any such
certificate in a name other than that of the Holder of the Security converted,
and the Company shall not be required to issue or deliver such certificates
unless or until the Person or Persons requesting the issuance thereof shall
have paid to the Company the amount of such tax or shall have established to
the satisfaction of the Company that such tax has been paid.

Section 1311.  Trustee and Conversion Agents Not Liable.

         Neither the Trustee nor any conversion agent shall at any time be 
under any duty or responsibility to any Holder of Securities to determine
whether any facts exist which may require any adjustment of the conversion
rate, or with respect to the nature or extent of any such adjustment when made,
or with respect to the method employed, or herein or in any supplemental
indenture provided to be employed, in making the same.  Neither the Trustee nor
any conversion agent shall be accountable with respect to the validity or value
(or the kind or amount) of any shares of Common Stock or of any securities or
cash or other property which may at any time be issued or delivered upon the
conversion of any Security, or makes any representation with respect thereto. 
Neither the Trustee nor any conversion agent shall be responsible for any
failure of the Company to make any cash payment or to issue, transfer or
deliver any shares of Common Stock or stock certificates or other securities or
property upon the surrender of any Security for the purpose of conversion, or,
subject to Section 601, with any of the covenants of the Company contained in
this Article Thirteen.


                               ARTICLE FOURTEEN
                                      
                         SUBORDINATION OF SECURITIES

Section 1401.  Securities Subordinate to Senior Indebtedness.

         The Company covenants and agrees, and each Holder of a Security by 
his acceptance thereof likewise covenants and agrees that, to the extent and in
the manner hereinafter set forth in this Article, the indebtedness represented
by the Securities and the payment of the principal of (and premium, if any) and
interest on each and all of the Securities are hereby expressly made
subordinate and subject in right of payment to the prior payment in full of all
Senior Indebtedness.

Section 1402.  Payment Over of Proceeds Upon Dissolution, Etc.

         Upon any distribution of assets of the Company in the event of (a) 
any insolvency or bankruptcy case or proceeding, or any receivership,
liquidation, reorganization or other similar case or proceeding in connection
therewith, relative to the Company or to its creditors, as such, or to its
assets, or (b) any liquidation, dissolution or other winding up of the Company,
whether voluntary or involuntary and whether or not involving insolvency or
bankruptcy, or (c) any assignment for the benefit of creditors or any other
marshalling of assets and liabilities of the Company, then and in any such
event the holders of Senior Indebtedness shall be entitled to receive payment
in full of all amounts due or to become due on or in respect of all Senior
Indebtedness, or provision shall be made for such payment in money or money's
worth, before the Holders of the Securities are entitled to receive any payment
on account of principal of (or premium, if any) or interest on the Securities,
and 


                                    - 68 -
<PAGE>   78
to that end the holders of Senior Indebtedness shall be entitled to receive, 
for application to the payment thereof, any payment or distribution of any 
kind or character, whether in cash, property or securities, including any such
payment or distribution which may be payable or deliverable by reason of the
payment of any other indebtedness of the Company being subordinated to the
payment of the Securities, which may be payable or deliverable in respect of
the Securities in any such case, proceeding, dissolution, liquidation or other
winding up or event. In furtherance of the foregoing, but not by way of
limitation thereof, in the event of any case or proceeding described in clause
(a) above with the result that the Company is excused from the obligation to
pay all or any part of the interest otherwise payable in respect of any Senior
Indebtedness during the period subsequent to the commencement of any such case
or proceeding, all or such part, as the case may be, of such interest shall be
payable out of, and to that extent shall diminish and be at the expense of,
reorganization dividends or other distributions in respect of the Notes.

         In the event that, notwithstanding the foregoing provisions of this 
Section, the Trustee or the Holder of any Security shall have received any
payment or distribution of assets of the Company of any kind or character,
whether in cash, property or securities, including any such payment or
distribution which may be payable or deliverable by reason of the payment of
any other indebtedness of the Company being subordinated to the payment of the
Securities, before all Senior Indebtedness is paid in full or payment thereof
provided for, and if such fact shall then have been made known to the Trustee,
or, as the case may be, such Holder, then and in such event such payment or
distribution shall be paid over or delivered forthwith to the trustee in
bankruptcy, receiver, liquidating trustee, custodian, assignee, agent or other
Person making payment or distribution of assets of the Company for application
to the payment of all Senior Indebtedness remaining unpaid, to the extent
necessary to pay all Senior Indebtedness in full, after giving effect to any
concurrent payment or distribution to or for the holders of Senior
Indebtedness.

         For purposes of this Article only, the words "cash, property or 
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other
corporation provided for by a plan of reorganization or readjustment the
payment of which is subordinated at least to the extent provided in this
Article with respect to the Securities to the payment of all Senior
Indebtedness which may at the time be outstanding; provided, however, that (i)
such Senior Indebtedness is assumed by the new corporation, if any, resulting
from any such reorganization or readjustment, and (ii) the rights of the
holders of the Senior Indebtedness are not, without the consent of such
holders, altered by such reorganization or readjustment.  The consolidation of
the Company with, or the merger of the Company into, another Person or the
liquidation or dissolution of the Company following the conveyance or other
disposition of its properties and assets substantially as an entirety to
another Person upon the terms and conditions set forth in Article Eight shall
not be deemed a dissolution, winding up, liquidation, reorganization,
assignment for the benefit of creditors or marshalling of assets and
liabilities of the Company for the purposes of this Section if the Person
formed by such consolidation or into which the Company is merged or the Person
which acquires by conveyance or other


                                    - 69 -
<PAGE>   79
disposition such properties and assets substantially as an entirety, as the
case may be, shall, as a part of such consolidation, merger, conveyance or
other disposition, comply with the conditions set forth in Article Eight.

Section 1403.  Prior Payment to Senior Indebtedness Upon Acceleration of 
               Securities.

         In the event that any Securities are declared due and payable before 
their Stated Maturity, then and in such event the holders of Senior
Indebtedness outstanding at the time such Securities so become due and payable
shall be entitled to receive payment in full of all amounts due or to become
due on or in respect of all such Senior Indebtedness, or provision shall be
made for such payment in money or money's worth, before the Holders of the
Securities are entitled to receive any payment (including any payment which may
be payable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities) by the Company on account
of the principal of (or premium, if any) or interest on the Securities or on
account of the purchase or other acquisition of Securities.

         In the event that, notwithstanding the foregoing, the Company shall 
make any payment to the Trustee or the Holder of any Securities prohibited by
the foregoing provisions of this Section, and if such facts shall then have
been made known to the Trustee or, as the case may be, such Holder, then and in
such event such payment shall be paid over and delivered forthwith to the
Company for the benefit of the holders of Senior Indebtedness.

         The provisions of this Section shall not apply to any payment with 
respect to which Section 1402 would be applicable.

Section 1404.  No Payment When Senior Indebtedness in Default.

         (a)   In the event and during the continuation of any default in the 
payment of principal (or premium, if any) or interest on any Senior
Indebtedness, or in the payment of any commitment or other fees in respect
thereof, or in the event that any event of default with respect to any Senior
Indebtedness shall have occurred and be continuing permitting the holders of
such Senior Indebtedness (or a trustee on behalf of the holders thereof) to
declare such Senior Indebtedness due and payable prior to the date on which it
would otherwise have become due and payable, unless and until such event of
default shall have been cured or waived or shall have ceased to exist and such
acceleration shall have been rescinded or annulled, or (b) in the event any
judicial proceeding shall be pending with respect to any such default in
payment or event of default; then no payment (including any payment which may
be payable by reason of the payment of any other indebtedness of the Company
being subordinated to the payment of the Securities) shall be made by the
Company on account of principal of (or premium, if any) or interest on the
Securities or on account of the purchase or other acquisition of Securities.
      

                                    - 70 -
<PAGE>   80
         In the event that, notwithstanding the foregoing, the Company shall 
make any payment to the Trustee or the Holder of any Security prohibited by the
foregoing provisions of this Section, and if such fact shall then have been
made known to the Trustee or, as the case may be, such Holder, then and in such
event such payment shall be paid over and delivered forthwith to the Company
for the benefit of the holders of Senior Indebtedness.

         The provisions of this Section shall not apply to any payment with 
respect to which Section 1402 would be applicable.

Section 1405.  Acknowledgment of Reliance.

         Each Holder of Notes by his acceptance thereof acknowledges and 
agrees that the subordination provisions included herein are, and are intended
to be, an inducement and a consideration to each holder of any Senior
Indebtedness, whether such Senior Indebtedness was created or acquired before
or after the issuance of Notes, to acquire and/or continue to hold such Senior
Indebtedness, and such holder of Senior Indebtedness shall be deemed
conclusively to have relied on such subordination provisions in acquiring
and/or continuing to hold such Senior Indebtedness.

Section 1406.  Subrogation to Rights of Holders of Senior Indebtedness.

         Subject to the payment in full of all Senior Indebtedness, the 
Holders of the Securities shall be subrogated to the extent of the payments or
distributions made to the holders of such Senior Indebtedness pursuant to the
provisions of this Article to the rights of the holders of such Senior
Indebtedness to receive payments or distributions of cash, property or
securities applicable to the Senior Indebtedness until the principal of (and
premium, if any) and interest on the Securities shall be paid in full.  For
purposes of such subrogation, no payments or distributions to the holders of
the Senior Indebtedness of any cash, property or securities to which the
Holders of the Securities or the Trustee would be entitled except for the
provisions of this Article, and no payments over pursuant to the provisions of
this Article to the Company or to the holders of Senior Indebtedness by Holders
of the Securities or the Trustee shall, as between the Company, its creditors
other than holders of Senior Indebtedness and the Holders of the Securities, be
deemed to be a payment or distribution by the Company to or on account of the
Securities.

Section 1407.  Provisions Solely to Define Relative Rights.

         The provisions of this Article are and are intended solely for the 
purpose of defining the relative rights of the Holders of the Securities, on
the one hand, and the holders of Senior Indebtedness, on the other hand. 
Nothing contained in this Article or elsewhere in this Indenture or in the
Securities is intended to or shall (a) impair, as among the Company, its
creditors and the Holders of the Securities, the obligation of the Company,
which is absolute and unconditional, and which, subject to the rights under
this Article of the holders of Senior Indebtedness, is intended to rank equally
with all other general 


                                    - 71 -
<PAGE>   81
obligations of the Company, to pay to the Holders of the Securities the
principal of (and premium, if any) and interest on the Securities as and when
the same shall become due and payable in accordance with their terms, or (b)
affect the relative rights against the Company of the Holders of the Securities
and creditors of the Company other than the holders of Senior Indebtedness, or
(c) prevent the Trustee or the Holder of any Security from exercising all
remedies otherwise permitted by applicable law upon default under this
Indenture, subject to the rights, if any, under this Article of the holders of
Senior Indebtedness to receive cash, property or securities otherwise payable
or deliverable to the Trustee or such Holder.

Section 1408.  Trustee to Effectuate Subordination.

         Each Holder of a Security by his acceptance thereof authorizes and 
directs the Trustee on his behalf to take such action as may be necessary or
appropriate to effectuate the subordination provided in this Article and
appoints the Trustee his attorney-in-fact for any and all such purposes.

Section 1409.  No Waiver of Subordination Provisions.

         No right of any present or future holder of any Senior Indebtedness 
to enforce subordination as herein provided shall at any time in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any act or failure to act in good faith by any such holder, or by any
noncompliance by the Company with the terms, provisions and covenants of this
Indenture, regardless of any knowledge thereof any such holder may have or be
otherwise charged with.

         Without in any way limiting the generality of the foregoing 
paragraph, the holders of Senior Indebtedness may, at any time and from time to
time, without the consent of or notice to the Trustee or the Holders of the
Securities, without incurring responsibility to the Holders of the Securities
and without impairing or releasing the subordination provided in this Article
or the obligations hereunder of the Holders of the Securities to the holders of
Senior Indebtedness, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, Senior Indebtedness, or otherwise amend or supplement in any manner
Senior Indebtedness or any instrument evidencing the same or any agreement
under which Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of Senior Indebtedness; and (iv) exercise or refrain from exercising
any rights against the Company and any other Person.

Section 1410.  Notice to Trustee.

         The Company shall give prompt written notice to the Trustee of any 
fact known to the Company which would prohibit the making of any payment to or
by the Trustee in respect of the Securities.  Failure to give such notice shall
not affect the subordination of the Securities to Senior Indebtedness. 
Notwithstanding the provisions of this Article or any other provision of this
Indenture, the Trustee shall not be charged with knowledge of the existence of
any facts which would prohibit the making of any payment to or by the 


                                    - 72 -
<PAGE>   82
Trustee in respect of the Securities, unless and until a Responsible Officer of
the Trustee shall have received written notice thereof from the Company or a
holder of Senior Indebtedness or from any trustee therefor; and, prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 601, shall be entitled in all respects to assume that no such facts
exist; provided, however, that if the Trustee shall not have received, at least
three Business Days prior to the date upon which by the terms hereof any such
money may become payable for any purpose (including without limitation, the
payment of the principal of, and premium, if any, or interest on any Security),
the notice with respect to such money provided for in this Section, then,
anything herein contained to the contrary notwithstanding, the Trustee shall
have full power and authority to receive such money and to apply the same to
the purpose for which such money was received and shall not be affected by any
notice to the contrary which may be received by it within three Business Days
prior to such date.

         Subject to the provisions of Section 601, the Trustee shall be 
entitled to rely on the delivery to it of a written notice by a Person
representing himself to be a holder of Senior Indebtedness (or a trustee on
behalf of such holder) to establish that such notice has been given by a holder
of Senior Indebtedness (or a trustee on behalf of any such holder).  In the
event that the Trustee determines in good faith that further evidence is
required with respect to the right of any Person as a holder of Senior
Indebtedness to participate in any payment or distribution pursuant to this
Article, the Trustee may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness
held by such Person, the extent to which such Person is entitled to participate
in such payment or distribution and any other facts pertinent to the rights of
such Person under this Article, and if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

Section 1411.  Reliance on Judicial Order or Certificate of Liquidating
               Agent.

         Upon any payment or distribution of assets of the Company referred 
to in this Article, the Trustee, subject to the provisions of Section 601, and
the Holders of the Securities shall be entitled to rely upon any order or
decree entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, liquidating trustee, custodian, receiver, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, the amount thereof or payable 
      

                                    - 73 -
<PAGE>   83
thereon, the amount or amounts paid or distributed thereon and all other 
facts pursuant thereto or to this Article.

Section 1412.  Trustee Not Fiduciary for Holders of Senior Indebtedness.

         The Trustee shall not be deemed to owe any fiduciary duty to the 
holders of Senior Indebtedness and shall not be liable to any such holders if
it shall in good faith mistakenly pay over or distribute to Holders of
Securities or to the Company or to any other Person cash, property or
securities to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article or otherwise.

Section 1413.  Rights of Trustee as Holder of Senior Indebtedness;
               Preservation of Trustee's Rights. 

         The Trustee in its individual capacity shall be entitled to 
all the rights set forth in this Article with respect to any Senior
Indebtedness which may at any time be held by it, to the same extent as any
other holder of Senior Indebtedness, and nothing in this Indenture shall
deprive the Trustee of any of its rights as such holder.

         Nothing in this Article shall apply to claims of, or payments to, 
the Trustee or any predecessor Trustee under or pursuant to Section 607.

Section 1414.  Article Applicable to Paying Agents.

         In case at any time any Paying Agent other than the Trustee shall 
have been appointed by the Company and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying
Agent within its meaning as fully for all intents and purposes as if such
Paying Agent were named in this Article in addition to or in place of the
Trustee; provided, however, that Section 1413 shall not apply to the Company or
any Affiliate of the Company if it or such Affiliate acts as Paying Agent.

Section 1415.  Certain Conversions Deemed Payment.

         For the purposes of this Article only, (1) the issuance and delivery 
of junior securities upon conversion of Securities in accordance with Article
Thirteen shall not be deemed to constitute a payment or distribution on account
of the principal of or premium or interest on Securities or on account of the
purchase or other acquisition of Securities, and (2)  the payment, issuance or
delivery of cash, property or securities (other than junior securities) upon
conversion of a Security shall be deemed to constitute payment on account of
the principal of such Security.  For the purposes of this Section, the term
"junior securities" means (a) shares of any stock of any class of the Company
and (b) securities of the Company which are subordinated in right of payment to
all Senior Indebtedness which may be outstanding at the time of issuance or
delivery of such securities to substantially the 
      
                                    - 74 -
<PAGE>   84
same extent as, or to a greater extent than, the Securities are so subordinated
as provided in this Article.  Nothing contained in this Article or elsewhere in
this Indenture or in the Securities is intended to or shall impair, as among
the Company, its creditors, other than holders of Senior Indebtedness and the
Holders of the Securities, the right, which is absolute and unconditional, of
the Holder of any Security to convert such Security in accordance with Article
Thirteen.

         This instrument may be executed in any number of counterparts, each

                                             February 3, 1995



Pogo Producing Company
Post Office Box 2504
Houston, Texas  77252-2504

Gentlemen:

         At your request we have prepared an estimate of the reserves, future
production, and income attributable to certain leasehold and royalty interests
of Pogo Producing Company and its wholly owned subsidiaries (the Company) as of
December 31, 1994.  In accordance with the requirements of FASB 69, our
estimates of the Company's net proved reserves as of December 31, 1991, 1992,
1993, and 1994, as contained in this report and our previous reports, are
presented in attached Table No. 1 together with a tabulation of the components
of the differences in the estimates as of such dates.  The Company's reserves
in the United States are located in the states of Colorado, Louisiana, New
Mexico, Oklahoma, Texas, and in state and federal waters offshore Louisiana and
Texas.  The Company's foreign reserves are located offshore Thailand.

         The estimated reserve volumes and future income amounts presented in
this report are related to hydrocarbon prices.  December 1994 hydrocarbon
prices were used in the preparation of this report as required by Securities
and Exchange Commission (SEC) and Financial Accounting Standards Bulletin No.
69 (FASB 69) guidelines; however, actual future prices may vary significantly
from December 1994 prices.  Therefore, volumes of reserves actually recovered
and amounts of income actually received may differ from the estimated
quantities presented in this report.  Our estimates of the proved net reserves
attributable to the interests of the Company as of December 31, 1994 are shown
below:

                 The "Liquid" reserves shown above are comprised of crude oil,
condensate, and natural gas liquids.  Natural gas liquids comprise 17 percent
of the Company's developed liquid reserves and 13 percent of the Company's
developed and undeveloped liquid reserves.  All hydrocarbon liquid reserves are
expressed in standard 42 gallon barrels.  All gas volumes are sales gas
expressed in MMCF at the pressure and temperature bases of the area where the
gas reserves are located.

                 The proved reserves presented in this report comply with the
SEC's Regulation S-X Part 210.4-10 Sec.  (a) as clarified by subsequent
Commission Staff Accounting Bulletins, and are based on the following
definitions and criteria:

                 Proved reserves of crude oil, condensate, natural gas, and
         natural gas liquids are estimated quantities that geological and
         engineering data demonstrate with reasonable certainty to be
         recoverable in the future from known reservoirs under existing
         conditions.  Reservoirs are considered proved if economic
         producibility is supported by actual production or formation tests.
         In certain instances, proved reserves are assigned on the basis of a
         combination of core analysis and electrical and other type logs which
         indicate the reservoirs are analogous to reservoirs in the same field
         which are producing or have demonstrated the ability to produce on a
         formation test.  The area of a reservoir considered proved includes
         (1) that portion delineated by drilling and defined by fluid contacts,
         if any, and (2) the adjoining portions not yet drilled that can be
         reasonably judged as economically productive on the basis of available
         geological and engineering data.  In the absence of data on fluid
         contacts, the lowest known structural occurrence of hydrocarbons
         controls the lower proved limit of the reservoir.  Proved reserves are
         estimates of hydrocarbons to be recovered from a given date forward.
         They may be revised as hydrocarbons are produced and additional data
         become available.  Proved natural gas reserves are comprised of
         non-associated, associated, and dissolved gas.  An appropriate
         reduction in gas reserves has been made for the expected removal of
         natural gas liquids, for lease and plant fuel, and the exclusion of
         non- hydrocarbon gases if they occur in significant quantities and are
         removed prior to sale.  Reserves that can be produced economically
         through the application of improved recovery techniques are included
         in the proved classification when these qualifications are met:  (1)
         successful testing by a pilot project or the operation of an installed
         program in the reservoir provides support for the engineering analysis
         on which the project or program was based, and (2) it is reasonably
         certain the project will proceed.  Improved recovery includes all
         methods for supplementing natural reservoir forces and energy, or
         otherwise increasing ultimate recovery from a reservoir, including (1)
         pressure maintenance, (2) cycling, and (3) secondary recovery in its
         original sense.  Improved recovery also includes the enhanced recovery
         methods of thermal, chemical flooding, and the use of miscible and
         immiscible displacement fluids.  Estimates of proved reserves do not
         include crude oil, natural gas, or natural gas liquids being held in
         underground storage.  Depending on the status of development, these
         proved reserves are further subdivided into:

                 (i)  "developed reserves" which are those proved reserves
                 reasonably expected to be recovered through existing wells
                 with existing equipment and operating methods, including (a)
                 "developed producing reserves" which are those proved
                 developed reserves reasonably expected to be produced from
                 existing completion intervals now open for production in
                 existing wells, and (b) "developed non-producing reserves"
                 which are those proved developed reserves which exist behind
                 the casing of existing wells which are reasonably expected to
                 be produced through these wells in the predictable future
                 where the cost of making such hydrocarbons available for
                 production should be relatively small compared to the cost of
                 a new well; and

                 (ii) "undeveloped reserves" which are those proved reserves
                 reasonably expected to be recovered from new wells on
                 undrilled acreage, from existing wells where a relatively
                 large expenditure is required, and from acreage for which an
                 application of fluid injection or other improved recovery
                 technique is contemplated where the technique has been proved
                 effective by actual tests in the area in the same reservoir.

                 from undrilled acreage are limited to those drilling units
                 offsetting productive units that are reasonably certain of
                 production when drilled.  Proved reserves for other undrilled
                 units are included only where it can be demonstrated with
                 reasonable certainty that there is continuity of production
                 from the existing productive formation.

                 Because of the direct relationship between volumes of proved
undeveloped reserves and development plans, we include in the proved
undeveloped category only reserves assigned to undeveloped locations that we
have been assured will definitely be drilled and reserves assigned to the
undeveloped portions of secondary or tertiary projects which we have been
assured will definitely be developed.

                 The Company has interests in certain tracts which have
substantial additional hydrocarbon quantities which cannot be classified as
proved and consequently are not included herein.  The Company has active
exploratory and development drilling programs which may result in the
reclassification of significant additional volumes to the proved category.

                 In accordance with the requirements of FASB 69, our estimates
of future cash inflows, future costs, and future net cash inflows before income
tax as of December 31, 1994 from this report and as of December 31, 1993 from
our previous report are presented below.

</TABLE>

                 Our estimates as of December 31, 1994 and 1993 of future cash
inflows, future costs, future net cash inflows before income tax, and present
value at 10 percent before income tax are shown individually for total
worldwide, total United States (onshore and offshore), and foreign areas in
Table No. 2 which is attached.

                 The future cash inflows are gross revenues before any
deductions.  The production costs were based on current data and include
production taxes, ad valorem taxes, and certain other items such as
transportation costs in addition to the operating costs directly applicable to
the individual leases or wells.  The development costs were based on current
data and include dismantlement and abandonment costs net of salvage for
properties where such costs are relatively significant.

                 The Company furnished us with gas prices in effect at December
31, 1994 and with its forecasts of future gas prices which take into account
SEC guidelines, current market prices, contract prices, and fixed and
determinable price escalations where applicable.  In accordance with SEC
guidelines, the future gas prices used in this report make no allowances for
future gas price increases

which may occur as a result of inflation nor do they account for seasonal
variations in gas prices which may cause future yearly average gas prices to be
somewhat lower than December gas prices.  For gas sold under contract, the
contract gas price including fixed and determinable escalations exclusive of
inflation adjustments, was used until the contract expires and then was
adjusted to the current market price for the area and held at this adjusted
price to depletion of the reserves.

                 The Company furnished us with liquid prices in effect at
December 31, 1994 and these prices were held constant to depletion of the
properties.  In accordance with SEC guidelines, changes in liquid prices
subsequent to December 31, 1994 were not considered in this report.

                 The estimates of future net revenue from the Company's foreign
property are based on existing law.  Operating costs for the leases and wells
in this report were based on the operating expense reports of the Company and
include only those costs directly applicable to the leases or wells.  When
applicable, the operating costs include a portion of general and administrative
costs allocated directly to the leases and wells under terms of operating
agreements.  Development costs were furnished to us by the Company and are
based on authorizations for expenditure for the proposed work or actual costs
for similar projects.  The current operating and development costs were held
constant throughout the life of the properties.  For properties located
onshore, this study did not consider the salvage value of the lease equipment
or the abandonment cost since both are relatively insignificant and tend to
offset each other.  The estimated net cost of abandonment after salvage was
included for offshore properties where abandonment costs net of salvage are
significant.  The estimates of the offshore net abandonment costs furnished by
the Company were accepted without independent verification.  No deduction was
made for indirect costs such as general administration and overhead expenses,
loan repayments, interest expenses, and exploration and development
prepayments.  The Company supplied data on accumulated gas production
imbalances which were taken into account in our estimates of future production
and income.

                 The estimates of reserves presented herein are based upon a
detailed study of the properties in which the Company owns an interest;
however, we have not made any field examination of the properties.  No
consideration was given in this report to potential environmental liabilities
which may exist nor were any costs included for potential liability to restore
and clean up damages, if any, caused by past operating practices.  The Company
has informed us that they have furnished us all of the accounts, records,
geological and engineering data and reports, and other data required for this
investigation.  The ownership interests, prices, and other factual data
furnished by the Company were accepted without independent verification.  The
estimates presented in this report are based on data available through December
1994.

                 The reserves included in this report are estimates only and
should not be construed as being exact quantities.  They may or may not be
actually recovered, and if recovered, the revenues therefrom and the actual
costs related thereto could be more or less than the estimated amounts.
Moreover, estimates of reserves may increase or decrease as a result of future
operations.

                 In general, we estimate that future gas production rates will
continue to be the same as the average rate for the latest available 12 months
of actual production until such time that the well or wells are incapable of
producing at this rate.  The well or wells were then projected to decline at
their decreasing delivery capacity rate.  Our general policy on estimates of
future gas production rates is adjusted when necessary to reflect actual gas
market conditions in specific cases.  The future production rates from wells
now on production may be more or less than estimated because of changes in
market demand or allowables set by regulatory bodies.  Wells or locations which
are not currently producing may start producing earlier or later than
anticipated in our estimates of their future production rates.

                 While it may reasonably be anticipated that the future prices
received for the sale of production and the operating costs and other costs
relating to such production may also increase or decrease from existing levels,
such changes were, in accordance with rules adopted by the SEC, omitted from
consideration in making this evaluation.

                 Neither we nor any of our employees have any interest in the
subject properties and neither the employment to make this study nor the
compensation is contingent on our estimates of reserves and future cash inflows
for the subject properties.
