3.   Credit Facility

     On December 28, 2001, the Company replaced its $75.0 million credit
facility with an unsecured $200.0 million credit facility ("Credit Facility")
with a group of seven banks. The borrowing base of the three-year Credit
Facility is re-determined on or about April 30 and September 30 each year. The
banks and Spinnaker also have the option to request one additional
re-determination each year. The borrowing base is determined by the banks, in
their usual and customary manner, and at their sole discretion. The amount of
the borrowing base is a function of the banks' view of the Company's reserve
profile as well as commodity prices. The current borrowing base is $100.0
million. The Company has the option to elect to use a base interest rate as
described below or the LIBOR rate plus, for each such rate, a spread based on
the percent of the borrowing base used at that time. The base interest rate
under the Credit Facility is a fluctuating rate of interest equal to the higher
of either Toronto-Dominion Bank's base rate for dollar advances made in the
United States or the Federal Funds Rate plus 0.5 percent per annum. The
commitment fee rate ranges from 0.3 percent to 0.5 percent, depending on the
borrowing base usage. The Credit Facility contains various covenants and
restrictive provisions. At September 30, 2002, the Company was in compliance
with the covenants and restrictive provisions and expects to remain in
compliance through December 31, 2002. As of November 12, 2002, the Company had
no outstanding borrowings under the Credit Facility.

4.   Equity Offering

     On April 3, 2002, the Company completed a public offering of 5,750,000
shares of common stock, par value $0.01 per share ("Common Stock"), at $41.50
per share, including the over-allotment option consisting of 750,000 shares.
After payment of underwriting discounts and commissions, the Company received
net proceeds of $227.9 million. On April 3, 2002, the Company used a portion of
the proceeds from the offering to repay outstanding borrowings of $37.0 million.
The remaining net proceeds were invested in short-term high quality investments
and are being used to fund a portion of the costs to develop the Company's deep
water oil discovery at Green Canyon Blocks 338/339 ("Front Runner"), to fund a
portion of exploration and other development activities and for general
corporate purposes, including possible acquisitions of properties or seismic
data.

5.   Derivatives and Hedging

     On January 1, 2001, the Company adopted Statement of Financial Accounting
Standards ("SFAS") No. 133, as amended, "Accounting for Derivative Instruments
and Hedging Activities." SFAS No. 133 established accounting and reporting
standards requiring that all derivative instruments be recorded in the balance
sheet as either an asset or liability measured at its fair value. SFAS No. 133
requires that changes in a derivative's fair value be realized currently in
earnings unless specific hedge accounting criteria are met. Accounting for
qualifying hedges allows derivative gains and losses to offset related results
on the hedged items in the statement of operations and requires a company to
formally document, designate and assess the effectiveness of transactions that
qualify for hedge accounting.

     The Company enters into New York Mercantile Exchange ("NYMEX") related swap
contracts and collar arrangements from time to time. The Company's swap
contracts and collar arrangements will settle based on the reported settlement
price on the NYMEX for the last trading day of each month for natural gas.

     In a swap transaction, the counterparty is required to make a payment to
the Company for the difference between the fixed price and the settlement price
if the settlement price is below the fixed price. The Company is required to
make a payment to the counterparty for the difference between the fixed price
and the settlement price if the settlement price is above the fixed price. As of
September 30, 2002, Spinnaker's commodity price risk management positions in
fixed price natural gas swap contracts and related fair value were as follows:

     In a collar arrangement, the counterparty is required to make a payment to
the Company for the difference between the fixed floor price and the settlement
price if the settlement price is below the fixed floor price. The Company is
required to make a payment to the counterparty for the difference between the
fixed ceiling price and the settlement price if the settlement price is above
the fixed ceiling price. Neither party is required to make a payment if the
settlement price falls between the fixed floor price and the fixed ceiling
price. As of September 30, 2002, Spinnaker's commodity price risk management
positions in natural gas collar arrangements and related fair value were as

gains of $1.2 million and $7.7 million in revenues in the third quarter and
first nine months of 2002, respectively. Based on future natural gas prices as
of September 30, 2002, the Company would reclassify a net loss of $10.2 million
from accumulated other comprehensive income (loss) to earnings within the next
twelve months. The amounts ultimately reclassified into earnings will vary due
to changes in the fair value of the open derivative contracts prior to
settlement.

     Subsequent to September 30, 2002, Spinnaker entered into additional swap
contracts for the fourth quarter of 2002. Spinnaker's current commodity price

7.   New Accounting Principle

     In June 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 143, "Accounting for Asset Retirement Obligations." SFAS No. 143 requires
that the fair value of a liability for an asset retirement obligation be
recognized in the period in which it is incurred with the associated asset
retirement costs being capitalized as a part of the carrying amount of the
long-lived asset. SFAS No. 143 also includes disclosure requirements that
provide a description of asset retirement obligations and reconciliation of
changes in the components of those obligations. The Company currently records
its plugging and abandonment costs, net of salvage value, with respect to its
natural gas and oil properties as depreciation, depletion and amortization
expense ("DD&A") using the units-of-production method. This statement will
require the Company to recognize a liability for the fair value of its plugging
and abandonment liability, excluding salvage value, with the associated costs as
part of its natural gas and oil property balance. The Company is still
evaluating the future financial effects of adopting SFAS No. 143 and will adopt
the standard effective January 1, 2003.

Critical Accounting Policies

     The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Significant estimates include DD&A of proved natural gas and oil properties.
Natural gas and oil reserve estimates, which are the basis for
unit-of-production DD&A and the full cost ceiling test, are inherently imprecise
and are expected to change as future information becomes available. The
Company's critical accounting policies are as follows:

   Full Cost Method of Accounting

     The Company uses the full cost method of accounting for its investments in
natural gas and oil properties. Under this method, all acquisition, exploration
and development costs, including certain related employee costs, incurred for
the purpose of exploring for and developing natural gas and oil are capitalized.
Acquisition costs include costs incurred to purchase, lease or otherwise acquire
property. Exploration costs include the costs of drilling exploratory wells,
including those in progress, geological and geophysical service costs and
depreciation of support equipment used in exploration activities. Development
costs include the costs of drilling development wells and costs of completions,
platforms, facilities and pipelines. Costs associated with production and
general corporate activities are expensed in the period incurred. Sales of
natural gas and oil properties, whether or not being amortized currently, are
accounted for as adjustments of capitalized costs, with no gain or loss
recognized, unless such adjustments would significantly alter the relationship
between capitalized costs and proved reserves of natural gas and oil.

   DD&A

     The Company computes the provision for DD&A of natural gas and oil
properties using the unit-of-production method based upon production and
estimates of proved reserve quantities. Unevaluated costs and related carrying
costs are excluded from the amortization base until the properties associated
with these costs are evaluated. In addition to costs associated with evaluated
properties, the amortization base includes estimated future development costs
and dismantlement, restoration and abandonment costs, net of estimated salvage
values.

     Certain future development costs may be excluded from amortization when
incurred in connection with major development projects expected to entail
significant costs to ascertain the quantities of proved reserves attributable to
the properties under development. The amounts that may be excluded are portions
of the costs that relate to the major development project and have not
previously been included in the amortization base and the estimated future
expenditures associated with the development project. Such costs may be excluded
from costs to be amortized until the earlier determination of whether additional
reserves are proved or impairment occurs.

     As of September 30, 2002, the Company excluded from the amortization base
estimated future expenditures of $27.0 million associated with common
development costs for its deep water discovery at Front Runner. This estimate of
future expenditures associated with common development costs is based on
existing proved reserves to total proved reserves expected to be established
upon completion of the Front Runner project.

     If the $27.0 million had been included in the amortization base as of
September 30, 2002, and no additional reserves were assigned to the Front Runner
project, the DD&A rate as of September 30, 2002 would have been $2.24 per
thousand cubic feet gas equivalent ("Mcfe"). All future development costs
associated with the deep water discovery at Front Runner are included in the
determination of estimated future net cash flows from proved natural gas and oil
reserves used in the full cost ceiling calculation, as discussed below.

   Full Cost Ceiling

     Capitalized costs of natural gas and oil properties, net of accumulated
DD&A and related deferred taxes, are limited to the estimated future net cash
flows from proved natural gas and oil reserves, including the effects of hedging
activities in place as of September 30, 2002, discounted at 10 percent, plus the
lower of cost or fair value of unproved properties, as adjusted for related
income tax effects (the full cost ceiling). If capitalized costs exceed the full
cost ceiling, the excess is charged to write-down of natural gas and oil
properties in the quarter in which the excess occurs.

     Given the volatility of natural gas and oil prices, it is probable that the
Company's estimate of discounted future net cash flows from proved natural gas
and oil reserves will change in the near term. If natural gas or oil prices
decline, even if for

                                       11



only a short period of time, or if the Company has downward revisions to its
estimated proved reserves, it is possible that write-downs of natural gas and
oil properties could occur in the future.

   Capitalized General and Administrative Expenses

     Under the full cost method of accounting, certain internal costs are
capitalized that are directly identified with acquisition, exploration and
development activities. These capitalized internal costs include salaries,
employee benefits, costs of consulting services and other related expenses and
do not include costs related to production, general corporate overhead or
similar activities. Spinnaker capitalized $1.4 million and $4.3 million of
general and administrative costs in the third quarter and first nine months of
2002, respectively.

   Unproved Properties

     The costs associated with unproved properties and properties under
development are not initially included in the amortization base and relate to
unevaluated leasehold acreage and delay rentals, seismic data, wells
in-progress, wells pending determination and capitalized interest. Unevaluated
leasehold costs, delay rentals and capitalized interest are either transferred
to the amortization base with the costs of drilling the related well or are
assessed quarterly for possible impairment or reduction in value. Unevaluated
leasehold costs, delay rentals and capitalized interest are transferred to the
amortization base if a reduction in value has occurred. The costs of seismic
data are transferred to the amortization base using the sum-of-the-year's-digits
method over a period of six years. The costs associated with wells in-progress
and wells pending determination are transferred to the amortization base once a
determination is made whether or not proved reserves can be assigned to the
property. The costs of drilling exploratory dry holes and associated leasehold
costs are included in the amortization base immediately upon determination that
the well is unsuccessful.

   Other

     The costs associated with seismic hardware and software are included in
other property and equipment. These costs are depreciated using the
straight-line method over three years, with the provision for depreciation
recorded to the amortization base. Spinnaker capitalized a provision of $0.4
million and $0.9 million related to seismic hardware and software costs in the
third quarter and first nine months of 2002, respectively.

   Three Months Ended September 30, 2002 as Compared to the Three Months Ended
September 30, 2001

     Revenues, including the effects of hedging activities, increased $6.7
million in the third quarter of 2002 compared to the third quarter of 2001. The
increase in revenues was primarily due to higher oil production in the third
quarter of 2002 compared to the third quarter of 2001. Excluding the effects of
hedging activities, natural gas revenues increased $1.4 million and oil and
condensate revenues increased $7.0 million. The net income associated with
hedging activities in the third quarter of 2002 decreased $1.6 million compared
to the third quarter of 2001.

     Production increased approximately 0.5 Bcfe in the third quarter of 2002
compared to the third quarter of 2001. Average daily production in the third
quarter of 2002 was 161 million cubic feet gas equivalent ("MMcfe") compared to
155 MMcfe in the same period of 2001. Natural gas revenues increased $1.4
million due to higher prices in the third quarter of 2002, although natural gas
production decreased 1.1 Bcf. Excluding the effects of hedging activities, third
quarter 2002 natural gas prices averaged $3.25 per Mcf compared to $2.91 per Mcf
in the third quarter of 2001. The production declines of certain producing
wells, particularly in the High Island 202 area, resulted in lower natural gas
production in the third quarter of 2002. Oil and condensate revenues increased
$7.0 million primarily due to higher production volumes of 268 thousand barrels
("MBbls"). Third quarter 2002 oil and condensate prices averaged $25.97 per
barrel compared to $25.66 in the same period

                                       13



of 2001. The Company estimates that its net production was reduced by
approximately 0.5 Bcfe in the third quarter of 2002 as a result of Tropical
Storms Fay and Isidore. The Company estimates that its net production will be
reduced by approximately 0.8 Bcfe in the fourth quarter of 2002 as a result of
Hurricane Lili, which caused damage to several pipelines and facilities in which
the Company owns an interest.

     Lease operating expenses increased $1.9 million in the third quarter of
2002 compared to the third quarter of 2001. Of the total increase in lease
operating expenses, approximately $3.0 million was attributable to wells on 11
new blocks that commenced production subsequent to September 30, 2001, offset in
part by decreases of $0.6 million in operating expenses associated with existing
wells and $0.5 million in workover expenses. The overall increase in the lease
operating expense rate per Mcfe in the third quarter of 2002 compared to the
same period in 2001 was primarily due to the production declines of certain
wells in the High Island 202 area where the lease operating rate was
significantly lower than other producing areas operated by the Company.

     DD&A increased $8.9 million in the third quarter of 2002 compared to the
third quarter of 2001. Of the total increase in DD&A, $8.0 million related to an
increase in the DD&A rate per Mcfe and $0.9 million related to higher production
volumes in the third quarter of 2002. The DD&A rate increased in the third
quarter of 2002 compared to the second quarter of 2002 primarily due to four
unsuccessful drilling operations. Because of additional unsuccessful drilling
operations experienced to date, the Company currently expects that the DD&A rate
will increase in the fourth quarter of 2002 to approximately $2.25 per Mcfe.

     General and administrative expenses increased approximately $0.8 million in
the third quarter of 2002 compared to the third quarter of 2001. The increase in
general and administrative expenses was primarily due to higher
employment-related costs resulting from the Company's recent growth in personnel
and increased professional services fees.

     Interest income decreased $0.5 million in the third quarter of 2002
compared to the third quarter of 2001 primarily due to lower average cash and
short-term investment balances and lower interest rates in the third quarter of
2002. Interest expense increased $0.1 million in the third quarter of 2002
compared to the third quarter of 2001 primarily due to higher commitment fees
and loan origination fee amortization in the third quarter of 2002.

     Income tax provision decreased $2.1 million in the third quarter of 2002
compared to the third quarter of 2001 due to lower earnings in the third quarter
of 2002. Income taxes were accrued at a 36 percent effective tax rate in the
third quarter of 2002 and 2001.

     The Company recognized net income of $7.1 million, or $0.22 per basic share
and $0.21 per diluted share, in the third quarter of 2002 compared to net income
of $10.8 million, or $0.40 per basic share and $0.38 per diluted share, in the
third quarter of 2001.

  Nine Months Ended September 30, 2002 as Compared to the Nine Months Ended
September 30, 2001

     Revenues, including the effects of hedging activities, decreased $50.4
million in the first nine months of 2002 compared to the first nine months of
2001. The decrease in revenues was primarily due to lower natural gas production
and prices in the first nine months of 2002. Excluding the effects of hedging
activities, natural gas revenues decreased $84.7 million and oil and condensate
revenues increased $10.8 million. Revenues from natural gas hedging activities
improved approximately $23.5 million in the first nine months of 2002 compared
to the same period of 2001.

     Production decreased approximately 5.1 Bcfe in the first nine months of
2002 compared to the first nine months of 2001. Average daily production in the
first nine months of 2002 was 129 MMcfe compared to 147 MMcfe in the same period
of 2001. Natural gas revenues decreased $84.7 million due to lower volumes of
7.7 Bcf and lower prices in the first nine months of 2002. Excluding the effects
of hedging activities, natural gas prices averaged $3.11 per Mcf in the first
nine months of 2002 compared to $4.67 per Mcf in the same period of 2001. The
production declines of certain producing wells, particularly in the High Island
202 area, and less than anticipated results from workovers resulted in lower
natural gas production in the first nine months of 2002. Oil and condensate
revenues increased $10.8 million primarily due to higher production volumes of
442 MBbls. Oil and condensate prices averaged $25.21 per barrel in the first
nine months of 2002 compared to $26.80 in the same period of 2001. The Company
estimates that its net production was reduced by approximately 0.5 Bcfe in the
third quarter of 2002 as a result of Tropical Storms Fay and Isidore. The
Company estimates that its net production will be reduced by approximately 0.8
Bcfe in the fourth quarter of 2002 as a result of Hurricane Lili, which caused
damage to several pipelines and facilities in which the Company owns an
interest.

                                       14



     Lease operating expenses increased $3.1 million in the first nine months of
2002 compared to the first nine months of 2001. Of the total increase in lease
operating expenses, approximately $4.4 million was attributable to wells on 11
new blocks that commenced production subsequent to September 30, 2001, offset in
part by a decrease of $1.3 million in operating expenses associated with
existing wells. The overall increase in the lease operating expense rate per
Mcfe in the first nine months of 2002 compared to the same period in 2001 was
primarily due to the production declines of certain wells in the High Island 202
area where the lease operating rate was significantly lower than other producing
areas operated by the Company.

     DD&A increased $7.2 million in the first nine months of 2002 compared to
the first nine months of 2001. Of the total increase in DD&A, $15.2 million
related to an increase in the DD&A rate, offset by $8.0 million related to lower
production volumes of 5.1 Bcfe in the first nine months of 2002 compared to the
same period of 2001. Because of additional unsuccessful drilling operations
experienced to date, the Company currently expects that the DD&A rate will
increase in the fourth quarter of 2002.

     General and administrative expenses increased approximately $1.4 million in
the first nine months of 2002 compared to the first nine months of 2001. The
increase in general and administrative expenses was primarily due to higher
employment-related costs resulting from the Company's recent growth and
increased professional services fees.

     Interest income decreased $2.4 million in the first nine months of 2002
compared to the first nine months of 2001 primarily due to lower average cash
and short-term investment balances and significantly lower interest rates in the
first nine months of 2002. Interest expense increased $0.3 million in the first
nine months of 2002 compared to the same period of 2001 primarily due to
interest on borrowings of $37.0 million in the first quarter of 2002 and higher
commitment fees. On April 3, 2002, the Company repaid all of its outstanding
borrowings of $37.0 million under the Credit Facility.

     Income tax provision decreased $23.5 million in the first nine months of
2002 compared to the first nine months of 2001 due to lower earnings in the
first nine months of 2002. Income taxes were accrued at a 36 percent effective
tax rate in the first nine months of 2002 and 2001.

     The Company recognized net income of $18.9 million, or $0.61 per basic
share and $0.59 per diluted share, in the first nine months of 2002 compared to
net income of $60.7 million, or $2.25 per basic share and $2.14 per diluted
share, in the same period of 2001.

Liquidity and Capital Resources

     The Company has experienced and expects to continue to experience
substantial capital requirements, primarily due to its active exploration and
development programs in the Gulf of Mexico. Capital expenditures in 2001 were
$288.8 million. Spinnaker has capital expenditure plans for 2002 totaling
approximately $322 million and has incurred capital expenditures of
approximately $287.4 million in the first nine months of 2002. During 2001,
Spinnaker participated in a significant deep water oil discovery, Front Runner,
with a 25 percent non-operator working interest. The Company participated in six
consecutive successful wells and sidetracks in testing the reservoirs on these
blocks. Spinnaker has incurred capital expenditures associated with Front Runner
of $20.3 million in the first nine months of 2002 and inception-to-date
expenditures of $49.7 million. The Company expects to incur approximately $103
million in future development costs, including approximately $10 million during
the remainder of 2002, $60 million in 2003, $15 million in 2004 and $18 million
thereafter.

     Natural gas and oil prices have a significant impact on the Company's cash
flows available for capital expenditures and its ability to borrow and raise
additional capital. The amount the Company can borrow under its Credit Facility
is subject to periodic re-determination based in part on changing expectations
of future prices. Lower prices may also reduce the amount of natural gas and oil
that the Company can economically produce. Additionally, the rapid production
declines of certain producing wells resulted in lower production in the first
nine months of 2002. Lower prices and/or lower production may decrease revenues,
cash flows and the borrowing base under the Credit Facility, thus reducing the
amount of financial resources available to meet the Company's capital
requirements.

     On April 3, 2002, the Company completed a public offering of 5,750,000
shares of Common Stock at $41.50 per share, including the over-allotment option
consisting of 750,000 shares. After payment of underwriting discounts and
commissions, the Company received net proceeds of $227.9 million. On April 3,
2002, the Company used a portion of the proceeds from the offering to repay
outstanding borrowings of $37.0 million. The remaining net proceeds were
invested in short-term high quality investments and are being used to fund a
portion of the costs to develop the Company's deep water oil discovery at

                                       15



Front Runner, to fund a portion of exploration and other development activities
and for general corporate purposes, including possible acquisitions of
properties or seismic data.

     While the Company believes that proceeds from the Common Stock offering,
working capital, cash flows from operations and available borrowings under its
Credit Facility will be sufficient to meet its capital requirements in the next
twelve months, additional debt or equity financing may be required in the future
to fund its growth and exploration and development programs. In the event
additional capital resources are unavailable, the Company may curtail its
drilling, development and other activities or be forced to sell some of its
assets on an untimely or unfavorable basis.

     Spinnaker has an effective shelf registration statement relating to the
potential public offer and sale by the Company or certain of its affiliates of
up to $500 million of any combination of debt securities, preferred stock,
common stock, warrants, stock purchase contracts and trust preferred securities
from time to time or when financing needs arise. The registration statement does
not provide assurance that the Company will or could sell any such securities.

     Cash and cash equivalents increased $22.2 million to $36.3 million at
September 30, 2002 from $14.1 million at December 31, 2001. The components of
the increase in cash and cash equivalents include $228.3 million provided by
financing activities, $88.5 million provided by operating activities and $294.6
million used in investing activities.

  Operating Activities

     Net cash provided by operating activities in the first nine months of 2002
decreased 56 percent to $88.5 million primarily due to lower natural gas
production and prices. Cash flow from operations is dependent upon the Company's
ability to increase production through its exploration and development programs
and the prices of natural gas and oil. The Company has made significant
investments to expand its operations in the Gulf of Mexico. These investments
are expected to increase the Company's average daily production in the fourth
quarter of 2002 as compared to the first nine months of 2002. However, the
Company currently expects that its average daily production in 2003 will decline
significantly from the levels it expects to achieve in the fourth quarter of
2002.

     The Company sells its natural gas and oil production under fixed or
floating market price contracts. Spinnaker enters into hedging arrangements from
time to time to reduce its exposure to fluctuations in natural gas and oil
prices and achieve more predictable cash flow. However, these contracts also
limit the benefits the Company would realize if prices increase. See "Item 3.
Quantitative and Qualitative Disclosures About Market Risk."

     The Company's cash flow from operations also depends on its ability to
manage working capital, including accounts receivable, accounts payable and
accrued liabilities. The net increase of $18.3 million in accounts receivable
was primarily related to an increase of $8.7 million in the natural gas and oil
revenue accrual at September 30, 2002 due to higher production and commodity
prices in September 2002 compared to December 2001 and an increase of $7.4
million in joint interest billing and trade receivables due to higher levels of
operated drilling and development activities in the third quarter of 2002
compared to the fourth quarter of 2001. The net decrease of $8.2 million in
accounts payable and accrued liabilities was primarily due to the reversal of
current deferred taxes of $7.2 million related to the fair value of open
derivative contracts at December 31, 2001. In connection with the fair value of
open derivative contracts at September 30, 2002, the Company recorded a net
deferred tax asset of $3.6 million in other current assets.

                                       16



  Investing Activities

     Net cash used in investing activities in the first nine months of 2002
increased 39 percent to $294.6 million compared to the first nine months of
2001. Net oil and gas property capital expenditures were $288.0 million and
other property and equipment capital expenditures were $6.6 million.

     As part of its strategy, the Company explores for natural gas and oil at
deeper drilling depths and in the deep waters of the Gulf of Mexico, where
operations are more difficult and costly than at shallower drilling depths and
in shallower waters. Along with higher risks and costs associated with these
areas, greater opportunity exists for reserve additions. The Company has
experienced and will continue to experience significantly higher drilling costs
for its deep shelf and deep water projects relative to the drilling costs on
shallower depth shelf projects in the Gulf of Mexico. The Company drilled 22
wells in the first nine months of 2002, 13 of which were successful. In 2001,
the Company drilled 35 wells, 19 of which were successful. Since inception and
through September 30, 2002, the Company has drilled 116 wells, 69 of which were
successful, representing a success rate of 59 percent. Dry hole costs, including
associated leasehold costs, were $33.6 million and $63.0 million in the three
and nine months ended September 30, 2002, respectively.

     The Company has capital expenditure plans for the fourth quarter of 2002 of
approximately $35 million. The Company has capital expenditure plans for 2003
totaling approximately $268 million, primarily for costs related to exploration
and development programs. The Company does not anticipate any significant
abandonment or dismantlement costs in 2003. Actual levels of capital
expenditures may vary due to many factors, including drilling results, natural
gas and oil prices, the availability of capital, industry conditions,
acquisitions, decisions of operators and other prospect owners and the prices of
drilling rig dayrates and other oilfield goods and services. In the first nine
months of 2002, the Company incurred acquisition, exploration and development
costs of $37.7 million, $160.6 million and $82.5 million, respectively. The
costs associated with unproved properties and properties under development not
included in the amortization base were $140.3 million as of September 30, 2002
and $102.9 million as of December 31, 2001 and included the following (in
thousands):

  Financing Activities

     Net cash provided by financing activities of $228.3 million in the first
nine months of 2002 included proceeds from the public offering of Common Stock
and $37.0 million in proceeds from and subsequent payments on borrowings. The
Company received net proceeds of $227.9 million from the offering on April 3,
2002, and used a portion of the proceeds from the offering to repay outstanding
borrowings of $37.0 million.

     On December 28, 2001, the Company replaced its $75.0 million credit
facility with an unsecured $200.0 million Credit Facility with a group of seven
banks. The borrowing base of the three-year Credit Facility is re-determined on
or about April 30 and September 30 each year. The banks and Spinnaker also have
the option to request one additional re-determination each year. The borrowing
base is determined by the banks, in their usual and customary manner, and at
their sole discretion. The amount of the borrowing base is a function of the
banks' view of the Company's reserve profile as well as commodity prices. The
current borrowing base is $100.0 million. The Company has the option to elect to
use a base interest rate as

                                       17



described below or the LIBOR rate plus, for each such rate, a spread based on
the percent of the borrowing base used at that time. The base interest rate
under the Credit Facility is a fluctuating rate of interest equal to the higher
of either Toronto-Dominion Bank's base rate for dollar advances made in the
United States or the Federal Funds Rate plus 0.5 percent per annum. The
commitment fee rate ranges from 0.3 percent to 0.5 percent, depending on the
borrowing base usage. The Credit Facility contains various covenants and
restrictive provisions. At September 30, 2002, the Company was in compliance
with the covenants and restrictive provisions. As of November 12, 2002, the
Company had no outstanding borrowings under the Credit Facility.

                                       18



Item 3.  Quantitative and Qualitative Disclosures About Market Risk

   Interest Rate Risk

     The Company is exposed to changes in interest rates. Changes in interest
rates affect the interest earned on cash and cash equivalents and the interest
rate paid on borrowings under the Credit Facility. The Company does not
currently use interest rate derivative instruments to manage exposure to
interest rate changes, but may do so in the future.

   Commodity Price Risk

     The Company's revenues, profitability and future growth depend
substantially on prevailing prices for natural gas and oil. Prices also affect
the amount of cash flow available for capital expenditures and the Company's
ability to borrow and raise additional capital. Lower prices may also reduce the
amount of natural gas and oil that the Company can economically produce. The
Company sells its natural gas and oil production under fixed or floating market
price contracts. Spinnaker enters into hedging arrangements from time to time to
reduce its exposure to fluctuations in natural gas and oil prices and to achieve
more predictable cash flow. However, these contracts also limit the benefits the
Company would realize if prices increase. These financial arrangements are fixed
price swap contracts and costless collar arrangements and are placed with major
trading counterparties the Company believes represent minimum credit risks.
Spinnaker cannot provide assurance that these trading counterparties will not
become credit risks in the future. Under its current hedging practice, the
Company generally does not hedge more than 66 2/3 percent of its estimated
twelve-month production quantities without the prior approval of the risk
management committee of the board of directors.

     See Note 5 to the Company's Notes to Interim Consolidated Financial
Statements (Unaudited) for a discussion of activities involving derivative
financial instruments during 2002 and the Company's current commodity price risk
management positions in fixed price natural gas swap contracts and natural gas
collar arrangements. To calculate the potential effect of the derivative
contracts on future revenues, the Company applied NYMEX natural gas forward
prices as of September 30, 2002 to the quantity of the Company's natural gas
production covered by those derivative contracts as of that date. The following
table shows the estimated potential effects of the derivative financial
instruments on future revenues (in thousands):

Item 4.  Controls and Procedures

(a)  Evaluation of disclosure controls and procedures. Within 90 days before the
     filing of this quarterly report on Form 10-Q, the Company's principal
     executive officer and principal financial officer evaluated the
     effectiveness of the Company's disclosure controls and procedures. Based on
     the evaluation, the Company's principal executive officer and principal
     financial officer believe that:

     .    the Company's disclosure controls and procedures are designed to
          ensure that information required to be disclosed by the Company in the
          reports it files or submits under the Securities Exchange Act of 1934
          is recorded, processed, summarized and reported within the time
          periods specified in the Securities and Exchange Commission's rules
          and forms; and

     .    the Company's disclosure controls and procedures were effective to
          ensure that material information was accumulated and communicated to
          the Company's management, including the Company's principal executive
          officer and principal financial officer, as appropriate to allow
          timely decisions regarding required disclosure.

(b)  Changes in internal controls. There have been no significant changes in the
     Company's internal controls or in other factors that could significantly
     affect the Company's internal controls subsequent to their evaluation, nor
     have there been any corrective actions with regard to significant
