                     POGO PRODUCING COMPANY AND SUBSIDIARIES

             Notes to Consolidated Financial Statements (Unaudited)

(1)  GENERAL INFORMATION -

     The consolidated financial statements included herein have been prepared 
by Pogo Producing Company (the "Company") without audit and include all 
adjustments (of a normal and recurring nature) which are, in the opinion of 
management, necessary for the fair presentation of interim results which are 
not necessarily indicative of results for the entire year. Certain prior year 
amounts have been reclassified to conform with current year presentation. The 
financial statements should be read in conjunction with the consolidated 
financial statements and notes thereto included in the Company's annual 
report on Form 10-K for the year ended December 31, 1997.

(2)  ACQUISITION -

     In August 1998, a wholly owned subsidiary of the Company merged with 
Arch Petroleum Inc. ("Arch") in a tax-free, stock for stock transaction 
through which Arch became a wholly owned subsidiary of the Company. The 
merger was initially accounted for as a pooling of interests which requires 
the financial results for all periods prior to the merger to be combined and 
restated as if the Company and Arch had always been combined. Consequently, 
the Company restated its consolidated financial statements for periods prior 
to the merger, including the third quarter and first nine months of 1997 and 
1998, to reflect the combined results of both the Company and Arch. A report 
on Form 10-Q for the periods ended September 30, 1998 was filed on that 
basis. The Company has recently concluded that, as a result of the current 
environment of low crude oil and natural gas prices, the Company must 
maintain maximum flexibility to address its cash flow needs, including the 
option of selling certain of the Company's assets. Under the current 
application of accounting principles, such transactions would preclude the 
pooling of interest method of accounting and require that the Company account 
for the merger using the purchase method of accounting.

     The Company is filing this amended report on Form 10-Q for the periods 
ended September 30, 1998 to restate that report to reflect the change from 
the pooling method of accounting to the purchase method of accounting. The 
merger agreement provides for a fixed exchange ratio of one share of the 
Company's common stock for each 10.4 shares of Arch common stock. In 
addition, holders of Arch preferred stock received one share of the Company's 
common stock for each 1.04 shares of Arch preferred stock held. As a result, 
2.5 million shares of the Company's common stock (valued at approximately 
$64.8 million) were issued in exchange for Arch preferred and common stock 
and its convertible debt. The value of the 2.5 million shares of the 
Company's common stock in excess of the book value of the net assets acquired 
(approximately $52.9 million) has been allocated to oil and gas properties 
and is being amortized using the units of production method over the life of 
the oil and gas reserves acquired. Expenses related to the acquisition of 
approximately $2.3 million ($1.5 million after taxes) have been expensed in 
the quarter just ended. Under the purchase method of accounting for the 
acquisition, the Arch results of operations are included in the consolidated 
results of operations from August 17, 1998, the date of acquisition, through 
September 30, 1998.

     The following summary presents unaudited pro forma consolidated results 
of operations as if the acquisition had occurred at the beginning of each 
period presented. The pro forma results are for illustrative purposes only 
and are not necessarily indicative of the operating results that would have 
occurred had the acquisition been consummated at that date, nor are they 
necessarily indicative of future operating results.

     Refer to Note 3 of Notes to Consolidated Financial Statements included 
in the Company's annual report on Form 10-K for the year ended December 31, 
1997 for a further discussion of the bank revolving credit agreement, the 
Company's uncommitted credit lines, the 2007 Notes and the 2006 Notes. On 
February 12, 1998, the Company announced its intent to redeem the 2004 Notes 
on March 16, 1998 at 103.3% of their principal amount plus accrued interest. 
Holders of $86,084,000 principal amount of the 2004 Notes elected to convert 
their notes into 3,879,726 common shares at $22.188 per share plus $640 in 
cash for fractional shares. The value of the shares issued was credited to 
common stock and additional capital lessthe unamortized debt issue expenses 
applicable to the 2004 Notes. The remaining $95,000 principal amount of the 
2004 Notes were redeemed for $98,135, representing 103.3% of the principal 
amount of such 2004 Notes. In June 1998, the Company entered into a master 
banker's acceptance agreement under which it may request banker's drafts for 
up to $20,000,000. The banker's drafts are on an as available basis and the 
bank does not have an obligation to accept the Company's request for drafts. 
Drafts drawn under this agreement are for a maximum maturity of 182 days; 
however, they are reflected as long-term debt as the Company has both the 
ability and intent to reborrow such amounts under its revolving credit 
agreement.

(5)  COMPREHENSIVE INCOME -

     During 1998, the Company adopted the Financial Accounting Standards 
Board's Statement of Financial Accounting Standards No. 130, Reporting 
Comprehensive Income ("SFAS 130"). Currently there are no significant amounts 
to be included in the computation of comprehensive income of the Company, as 
defined, that are required to be disclosed under the provisions of SFAS 130. 
As such, total comprehensive income and net income (loss) are the same for 
the three and nine month periods ended September 30, 1998 and 1997, 
respectively.

(6)  EARNINGS PER SHARE -

     In 1997, the Company adopted the Financial Accounting Standards Board's 
Statement of Financial Accounting Standards No. 128, Earnings Per Share 
("SFAS 128"). Prior periods have been restated in conformity with the 
provisions of SFAS 128. Earnings per common share (basic earnings per share) 
are based on the weighted average number of shares of common stock 
outstanding during the periods. Earnings per share and potential common share 
(diluted earnings per share) consider the effect of dilutive securities as 
set out below in thousands, except per share amounts:

(7)  IMPACT OF SFAS 133 -

     In June 1998, the Financial Accounting Standards Board issued Statement 
of Financial Accounting Standards No. 133, Accounting for Derivative 
Instruments and Hedging Activities ("SFAS 133"). SFAS 133 establishes 
accounting and reporting standards requiring that every derivative instrument 
(including certain derivative instruments embedded in other contracts) be 
recorded in the balance sheet as either an asset or liability measured at its 
fair market value and that changes in the derivative's fair market value be 
recognized currently in earnings unless specific hedge accounting criteria 
are met. SFAS 133 is effective for the Company in 2000 but early adoption is 
allowed. The Company has not yet quantified the impacts of adopting SFAS 133 
or determined the timing or method of adoption. However, SFAS 133 could 
increase volatility in earnings and other comprehensive income should the 
Company enter into transactions covered by this pronouncement.

                  Financial Condition and Results of Operations

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND 
RESULTS OF OPERATIONS.

     This discussion should be read in conjunction with Management's Discussion
and Analysis of Financial Condition and Results of Operations included in the
Company's annual report on Form 10-K for the year ended December 31, 1997.
Certain statements contained herein are "Forward Looking Statements" and are
thus prospective. As further discussed in the Company's annual report on Form
10-K for the year ended December 31, 1997, such forward-looking statements are
subject to risks, uncertainties and other factors that could cause actual
results to differ materially from future results expressed or implied by such
forward-looking statements. This amendment to the Company's Form 10-Q for the
period ended September 30, 1998 reflects a change in accounting method for the
Company's acquisition of Arch Petroleum Inc. ("Arch") on August 17, 1998 from
the "pooling of interests" method to the "purchase" method. For an explanation
of the purpose for the change of accounting methods, please see Part II, Item 5,
of this amended Form 10-Q.

RESULTS OF OPERATIONS --

INCOME AND REVENUE DATA

NET INCOME (LOSS)

     The Company reported a net loss of $8,322,000 for the third quarter of 1998
or $0.22 per share (on both a basic and a diluted basis) compared to net income
for the third quarter of 1997 of $7,386,000 or $0.22 per share ($8,156,000 or
$0.21 on a diluted basis). For the first nine months of 1998, the Company
reported a net loss of $10,806,000 or $0.29 per share (on both a basic and a
diluted basis) compared to net income for the first nine months of 1997 of
$29,378,000 or $0.88 per share ($31,689,000 or $0.83 on a diluted basis). Among
other items affecting net income for the third quarter and first nine months of
1998, were non-recurring expenses totaling approximately $2,285,000 ($1,485,000
or $0.04 per share on an after-tax basis), related to the Company's acquisition
of Arch.

     Earnings per share are based on the weighted average number of common
shares outstanding for the third quarter and first nine months of 1998 of
38,781,000 and 37,171,000, respectively, compared to 33,403,000 and 33,374,000,
respectively, for the third quarter and first nine months of 1997. The increases
in the weighted average number of common shares outstanding for the 1998
periods, compared to the 1997 periods, resulted primarily from the issuance of
3,882,023 shares of its common stock upon the conversion of the Company's 5 1/2%
Convertible Subordinated Notes due 2004 (the "2004 Notes") prior to their being
redeemed on March 16, 1998, the issuance as of August 17, 1998, of approximately
2,500,000 shares of common stock to former holders of Arch capital stock and
convertible debt securities in connection with the merger and, to a lesser
extent, the issuance of common stock upon the exercise of stock

options pursuant to the Company's stock option plans. Earnings per share 
computations on a diluted basis in the 1998 periods are identical to basic 
earnings per share computations because there were no securities of the 
Company that were dilutive during the periods. Earnings per share 
computations on a diluted basis in the 1997 periods primarily reflect 
additional shares of common stock issuable upon the assumed conversion of the 
2004 Notes and the elimination of related interest requirements, as adjusted 
for applicable federal income taxes and, to a lesser extent, the assumed 
exercise of options to purchase common shares. The weighted average number of 
common shares outstanding on a diluted basis for the third quarter and first 
nine months of 1997 were 38,091,000 and 38,064,000, respectively.

REVENUES

     TOTAL REVENUES

     The Company's total revenues for the third quarter of 1998 were
$46,179,000, a decrease of approximately 40% compared to total revenues of
$77,177,000 for the third quarter of 1997. The decrease in the Company's total
revenues for the third quarter of 1998, compared to the third quarter of 1997,
resulted primarily from a decrease in revenues from the Company's oil and gas
operations that was only partially offset by an increase in the revenues from
the Company's pipelines and other miscellaneous items. The Company's total
revenues for the first nine months of 1998 were $159,572,000, a decrease of
approximately 26% compared to total revenues of $215,231,000 for the first nine
months of 1997. The decrease in the Company's total revenues for the first nine
months of 1998, compared to the first nine months of 1997, resulted primarily
from decreases in revenue from the Company's oil and gas operations and, to a
lesser extent, a decline in revenue from the sale of non- strategic properties,
pipeline sales revenues and other miscellaneous items. Total revenues for the
third quarter and first nine months of 1998 reflect the inclusion of pipeline
revenues from Saginaw Pipeline, L.C. and its marketing subsidiary, Industrial
Natural Gas, L.C., which the Company acquired through its acquisition of Arch on
August 17, 1998. Total revenues for the first nine months of 1997 include a net
gain of $1,459,000 on the sale of a compressor by the Company during the first
half of 1997.

     OIL AND GAS REVENUES

     The following table reflects an analysis of differences in the Company's
oil and gas revenues (expressed in thousands of dollars) between the third
quarter and first nine months of 1998 and the same periods in the preceding
year.

     Prices and production volumes attributable to the Company's operations in
Canada are included in the Company's domestic oil and gas prices and production
volumes. This information is not presented separately because the Company does
not believe that such information is material to an understanding of the
Company's results of operations for the periods presented due to the relatively
small portion of the Company's oil and gas revenues which were attributable to
such operations during the applicable periods.

     NATURAL GAS PRICES. Prices per thousand cubic feet ("Mcf") that the Company
received for its natural gas production during the third quarter of 1998
averaged $1.93 per Mcf, a decrease of approximately 14% from an average price of
$2.25 per Mcf that the Company received for its natural gas production during
the third quarter of 1997. Prices that the Company received for its natural gas
production during the first nine months of 1998 averaged $2.04 per Mcf, a
decrease of approximately 12% from an average price of $2.31 per Mcf that the
Company received for its natural gas production during the first nine months of
1997.

     DOMESTIC PRICES. Prices that the Company received for its domestic natural
gas production during the third quarter of 1998 averaged $2.01 per Mcf, a
decrease of approximately 13% from an average price of $2.31 per Mcf that the
Company received for its domestic natural gas production during the third
quarter of 1997. Prices that the Company received for its domestic natural gas
production during the first nine months of 1998 averaged $2.13 per Mcf, a
decrease of approximately 10% from an average price of $2.37 per Mcf that the
Company received for its domestic natural gas production during the first nine
months of 1997.

                  Financial Condition and Results of Operations

     THAILAND PRICES. The Company's Tantawan Field located in the Kingdom of
Thailand commenced production of natural gas and liquid hydrocarbons in February
1997. During the third quarter of 1998, the prices that the Company received
under its long term gas sales contract for natural gas production from the
Tantawan Field averaged approximately 69 Thai Baht per Mcf. Based on the Thai
Baht to U.S. dollar exchange rates in effect at the time that such production
was recorded on the Company's financial statements, the average price in U.S.
dollars that the Company recorded during the third quarter and first nine months
of 1998 for such production was approximately $1.73 per Mcf, a decrease of
approximately 14% from an average price of $2.00 per Mcf that the Company
recorded in the third quarter and first nine months of 1997. The price that the
Company receives under its gas sales agreement normally adjusts on a semi-annual
basis. However, the gas sales agreement provides for adjustment on a more
frequent basis in the event that certain indices and factors on which the price
is based fluctuate outside a given range. Due to the volatility of the Thai Baht
and the current economic difficulties in the Kingdom of Thailand and throughout
Southeast Asia, the price that the Company received under the gas sales
agreement was adjusted several times during the first nine months of 1998. The
Company cannot predict what the Baht to dollar exchange rate may be in the
future. Moreover, it is anticipated that this exchange rate will remain
volatile.

     NATURAL GAS PRODUCTION. The Company's total natural gas production during
the third quarter of 1998 averaged 140.4 million cubic feet ("MMcf") per day, a
decrease of approximately 32% from an average of 206.1 MMcf per day that the
Company produced during the third quarter of 1997. The Company's total natural
gas production during the first nine months of 1998 averaged 164.4 MMcf per day,
a decrease of approximately 11% from an average of 184.5 MMcf per day that the
Company produced during the first nine months of 1997.

     DOMESTIC PRODUCTION. The Company's domestic natural gas production during
the third quarter of 1998 averaged 105.2 MMcf per day, a decrease of
approximately 37% from an average of 166.7 MMcf per day that the Company
produced during the third quarter of 1997. The decrease in the Company's natural
gas production during the third quarter of 1998, compared to the third quarter
of 1997, was related in large measure to decreased production from the Company's
East Cameron Block 334 "E" platform, and to a lesser extent, three periods in
the third quarter of 1998 during which most of the Company's offshore production
was shut-in as a precautionary measure due to hurricanes in the Gulf of Mexico.
The decrease in production was partially offset by increased production from the
Company's onshore properties located in South Texas and South Louisiana. The
Company's domestic natural gas production during the first nine months of 1998
averaged 125.5 MMcf per day, a decrease of approximately 18% from an average of
152.4 MMcf per day that the Company produced during the first nine months of
1997. The decrease in the Company's natural gas production during the first nine
months of 1998, compared to the first nine months of 1997, was related in large
measure to decreased production from the Company's East Cameron Block 334 "E"
platform, as well as the previously discussed weather related downtime and
natural production declines, that was partially offset by increased production
from the Company's onshore properties located in South Texas and South
Louisiana. As of December 21,

1998, the Company was not a party to any future natural gas sales contracts.

     THAILAND PRODUCTION. During the third quarter of 1998, the Company's share
of natural gas production from the Tantawan Field averaged approximately 35.3
MMcf per day, a decrease of approximately 10% from an average of 39.3 MMcf per
day that the Company produced during the third quarter of 1997. The decrease in
the Company's average daily natural gas production from the Tantawan Field
during the third quarter of 1998, compared to the third quarter of 1997, is
primarily related to declining production from existing wells, the need to
shut-in existing wells while drilling additional wells from the same platform,
and the decision to emphasize oil and condensate production from the Tantawan
Field. As a result of these factors, commencing on October 1, 1998, the Company
and its joint venture partners are currently delivering less natural gas than is
being nominated by the Petroleum Authority of Thailand ("PTT") under the natural
gas contract governing the Tantawan Field. This could result in the Company
receiving only 75% of the current contract price on a portion of its future
natural gas sales to PTT. The Company is taking actions that it currently
believes will minimize the penalty that it will incur on future gas sales to PTT
by, among other things, increasing production from the Tantawan Field. The
Company's share of natural gas production from the Tantawan Field during the
first nine months of 1998 averaged 38.9 MMcf per day, an increase of
approximately 21% from an average of 32.1 MMcf per day that the Company produced
during the first nine months of 1997. The increase in the Company's average
daily natural gas production from the Tantawan Field during the first nine
months of 1998, compared to the first nine months of 1997, reflects the fact
that production from the Tantawan Field did not commence until early in February
1997 and did not achieve sustained commercial production rates until March 15,
1997.

     CRUDE OIL AND CONDENSATE PRICES. Prices received by the Company for its
crude oil and condensate production during the third quarter of 1998 averaged
$12.85 per barrel, a decrease of approximately 31% from an average price of
$18.62 per barrel that the Company received during the third quarter of 1997.
Prices that the Company received for its crude oil and condensate production
during the first nine months of 1998 averaged $13.49 per barrel, a decrease of
approximately 31% from an average price of $19.58 per barrel that the Company
received during the first nine months of 1997.

     DOMESTIC PRICES. Prices received by the Company for its domestic crude oil
and condensate production during the third quarter of 1998 averaged $12.78 per
barrel, a decrease of approximately 31% from an average price of $18.42 per
barrel that the Company received during the third quarter of 1997. Prices that
the Company received for its domestic crude oil and condensate production during
the first nine months of 1998 averaged $13.44 per barrel, a decrease of
approximately 32% from an average price of $19.69 per barrel that the Company
received during the first nine months of 1997.

     THAILAND PRICES. Since the inception of production from the Tantawan Field,
crude oil and condensate have been stored in a Floating Production, Storage and
Offloading System (the

"FPSO") until an economic quantity is accumulated for offloading and sale. 
The first such sale of crude oil and condensate from the Tantawan Field 
occurred in July 1997. The price that the Company recorded for its crude oil 
and condensate production stored on the FPSO for the third quarter of 1998 
was $13.08 per barrel, a decrease of approximately 34% from the price of 
$19.83 per barrel that was recorded for the third quarter of 1997. The price 
that the Company recorded for its crude oil and condensate production stored 
on the FPSO for the first nine months of 1998 was $13.72 per barrel, a 
decrease of approximately 27% from the price of $18.84 per barrel that was 
recorded for the first nine months of 1997. Prices that the Company receives 
for its crude oil and condensate production from Thailand are based on world 
benchmark prices, which are denominated in dollars. In addition, the Company 
is generally paid for its crude oil and condensate production from Thailand 
in U.S. dollars.

     CRUDE OIL AND CONDENSATE PRODUCTION. The Company's total crude oil and
condensate production during the third quarter of 1998 averaged 15,722 barrels
per day, a decline of approximately 8% from an average of 17,171 barrels per day
during the third quarter of 1997. The Company's total crude oil and condensate
production during the first nine months of 1998 averaged 16,090 barrels per day,
an increase of approximately 1% from an average of 15,856 barrels per day during
the first nine months of 1997.

     DOMESTIC PRODUCTION. The Company's domestic crude oil and condensate
production during the third quarter of 1998 averaged 13,124 barrels per day, a
decrease of approximately 12% from an average of 14,869 barrels per day during
the third quarter of 1997. The Company's domestic crude oil and condensate
production during the first nine months of 1998 averaged 13,317 barrels per day,
a decrease of approximately 4% from an average of 13,927 barrels per day during
the first nine months of 1997. The decrease in the Company's domestic crude oil
and condensate production during the third quarter and first nine months of
1998, compared to the third quarter and first nine months of 1997, resulted
primarily from a decrease in condensate production from the Company's East
Cameron Block 334 "E" platform, which was in part due to damage sustained in a
marine accident at the crude oil and condensate pipeline from the platform, that
was only partially offset by increased production from the Company's ongoing
development drilling and workover programs in the offshore and onshore Gulf of
Mexico regions. As of December 21, 1998, the Company was not a party to any
crude oil swaps or futures contracts.

     THAILAND PRODUCTION. During the third quarter of 1998, the Company's share
of crude oil and condensate production from the Tantawan Field averaged 2,598
barrels per day, an increase of approximately 13% from an average of 2,304
barrels per day during the third quarter of 1997. The increase in the Company's
crude oil and condensate production from the Tantawan Field during the third
quarter of 1998, compared to the third quarter of 1997, resulted primarily from
the Company's efforts to emphasize oil production from the field. The Company's
share of crude oil and condensate production from the Tantawan Field during the
first nine months of 1998 averaged 2,773 barrels per day, an increase of
approximately 44% from an average of 1,930 barrels per day during the first nine
months of 1997. The increase in the Company's average daily

crude oil and condensate production from the Tantawan Field during the first 
nine months of 1998, compared to the first nine months of 1997, primarily 
reflects the fact that production from the Tantawan Field did not commence 
until early in February 1997 and did not achieve sustained commercial 
production rates until March 15, 1997.

     NGL PRODUCTION. The Company's oil and gas revenues, and its total liquid
hydrocarbon production volumes, reflect the production and sale by the Company.
The Company's NGL revenues for the third quarter and first nine months of 1998
decreased $3,115,000 and $3,597,000, from the third quarter and first nine
months of 1997, respectively. The decrease in the Company's NGL for the third
quarter of 1998, compared to the third quarter of 1997, resulted from a decrease
in the Company's NGL production from its domestic offshore properties due, in
part, to the Company's recent decision not to remove NGL from a portion of its
domestic natural gas production because it has not been economically
advantageous to do so. This decision is reviewed by the Company on an ongoing
basis and is largely dependent on the relationship between current natural gas
and NGL prices and the cost of processing natural gas to separate NGL. In
addition, the decline is also attributable to a decrease in the average price
that the Company received for its NGL production volumes. The decrease in the
Company's NGL for the first nine months of 1998, compared to the first nine
months of 1997, was related to both a decrease in NGL production volumes from
the Company's domestic offshore properties and a decrease in the price that the
Company received for its NGL production volumes.

     TOTAL LIQUID HYDROCARBON PRODUCTION. The Company's average liquid
hydrocarbon production during the third quarter of 1998 was 17,809 barrels per
day, a decrease of approximately 17% from an average liquid hydrocarbon
production of 21,557 barrels per day during the third quarter of 1997. The
Company's average liquid hydrocarbon production during the first nine months of
1998 was 18,858 barrels per day, a decrease of approximately 2% from an average
liquid hydrocarbon production of 19,280 barrels per day during the first nine
months of 1997.

OPERATING COSTS AND EXPENSES

     LEASE OPERATING EXPENSES

     Company-wide lease operating expenses for the third quarter of 1998 were
$18,612,000, an increase of approximately 12% from lease operating expenses of
$16,628,000 for the third quarter of 1997. Company-wide lease operating expenses
for the first nine months of 1998 were $51,196,000, an increase of approximately
13% from lease operating expenses of $45,116,000 for the first nine months of
1997. A discussion of lease operating expenses attributable to the Company's
operations in Canada is included in the Company's domestic lease operating
expenses. The information is not presented separately because the Company does
not believe that such information is material to an understanding of the
Company's results of operations for the periods presented due to the relatively
small portion of the Company's lease operating

                  Financial Condition and Results of Operations

expenses which were attributable to such operations during the applicable 
periods.

     DOMESTIC LEASE OPERATING EXPENSES. The Company's domestic lease operating
expenses for the third quarter of 1998 were $12,523,000, an increase of
approximately 18% from domestic lease operating expenses of $10,603,000 for the
third quarter of 1997. The increase in domestic lease operating expenses for the
third quarter of 1998, compared to the third quarter of 1997, resulted primarily
from expenses related to purchasing natural gas for transportation and
subsequent resale on the pipeline system acquired in the merger with Arch,
operating expenses related to the pipeline system and increased expenses on
certain properties acquired in the merger with Arch, which were partially offset
by a cost savings program instituted by the Company, including the sale of
certain non-strategic properties with high operating costs and entering into
cost sharing arrangements with its industry partners in the offshore Gulf of
Mexico. The Company's domestic lease operating expenses for the first nine
months of 1998 were $35,249,000, an increase of approximately 11% from domestic
lease operating expenses of $31,802,000 for the first nine months of 1997. The
increase in domestic lease operating expenses for the first nine months of 1998,
compared to the first nine months of 1997, were affected by a non-recurring
maintenance project on the Company's East Cameron 334 "E" platform during the
first quarter of 1998 and by expenses related to purchasing natural gas for
transportation and subsequent resale on the pipeline system acquired in the
merger with Arch, operating expenses related to the pipeline system for which no
corresponding expenses were recorded during the first nine months of 1997. In
addition, lease operating expenses for the first nine months of 1997 were
reduced by a $954,000 refund in connection with the Company's audit of a joint
venture partner, for which no corresponding refund of a similar magnitude was
obtained in the first nine months of 1998.

     THAILAND LEASE OPERATING EXPENSES. The Company's lease operating expenses
in the Kingdom of Thailand for the third quarter of 1998 were $6,089,000, an
increase of approximately 1% from lease operating expenses of $6,025,000 for the
third quarter of 1997. The increase in lease operating expenses in the Kingdom
of Thailand for the third quarter of 1998, compared to the third quarter of
1997, was primarily related to increased production related activity, including
the addition of two production platforms, which was almost entirely offset by
cost savings resulting from recently instituted cost control efforts. The
Company's lease operating expenses in the Kingdom of Thailand for the first nine
months of 1998 were $15,947,000, an increase of approximately 20% from lease
operating expenses of $13,314,000 for the first nine months of 1997. The
increase in lease operating expenses in the Kingdom of Thailand for the first
nine months of 1998, compared to the first nine months of 1997, was primarily
related to the fact that prior to the commencement of production in the Tantawan
Field on February 1, 1997, no lease operating expenses were incurred by the
Company in Thailand. Consequently, the Company does not believe that a
comparison of lease operating expenses in the Kingdom of Thailand between the
first nine months of 1998 and the first nine months of 1997 is meaningful. A
substantial portion of the Company's lease operating expenses in the Kingdom of
Thailand relate to lease payments made by a subsidiary of the Company in
connection with its bareboat charter

during the third quarters of 1998 and 1997, and $8,318,000 and $7,404,000 
(net to the Company's interest) for the first nine months of 1998 and 1997, 
respectively.

     GENERAL AND ADMINISTRATIVE EXPENSES

     General and administrative expenses for the third quarter of 1998 were 
$8,556,000, an increase of approximately 79% from general and administrative 
expenses of $4,789,000 for the third quarter of 1997. General and 
administrative expenses for the first nine months of 1998 were $19,843,000, 
an increase of approximately 26% from general and administrative expenses of 
$15,746,000 for the first nine months of 1997. The increase in general and 
administrative expenses for the third quarter and first nine months of 1998, 
compared with the third quarter and first nine months of 1997, was primarily 
related to a number of non-recurring expenses arising in connection with the 
Company's acquisition of Arch totaling approximately $2,285,000, that 
included severance payments to former officers and employees of Arch. In 
addition, the increase in general and administrative expense was 
attributable, in part, to an increase in the size of the Company's work force 
and normal salary and concomitant benefit expense adjustments.

     EXPLORATION EXPENSES

     Exploration expenses consist primarily of rental payments required under
oil and gas leases to hold non-producing properties ("delay rentals") and
geological and geophysical costs which are expensed as incurred. Exploration
expenses for the third quarter of 1998 were $1,426,000, a decrease of
approximately 24% from exploration expenses of $1,870,000 for the third quarter
of 1997. Exploration expenses for the first nine months of 1998 were $7,260,000,
a decrease of approximately 7% from exploration expenses of $7,823,000 for the
first nine months of 1997. The decreases in exploration expenses for the third
quarter and first nine months of 1998, compared to the third quarter and first
nine months of 1997, resulted primarily from decreased geophysical activity in
the Gulf of Mexico and West Texas, and a decrease in delay rental payments, that
were partially offset, during the comparable nine month periods, by increased
geophysical activity by the Company in East Texas, South Louisiana and in the
Gulf of Thailand.

     DRY HOLE AND IMPAIRMENT EXPENSES

     Dry hole and impairment expenses relate to costs of unsuccessful wells
drilled, along with impairments due to decreases in expected reserves from
producing wells. The Company's dry hole and impairment expenses for the third
quarter of 1998 were $5,128,000, an increase of approximately 167% from dry hole
and impairment expenses of $1,919,000 for the third quarter of 1997. The
Company's dry hole and impairment expenses for the first nine months of 1998
were

$7,906,000, an increase of approximately 14% from dry hole and impairment
expenses of $6,926,000 for the first nine months of 1997.

     DEPRECIATION, DEPLETION AND AMORTIZATION EXPENSES

     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. Proved properties
are reviewed whenever events or changes in circumstances indicate that the value
of such property on the Company's books may not be recoverable. 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, as determined in the preceding paragraph, plus
future costs to abandon offshore wells and platforms, and is determined on a
cost center by cost center basis using the units of production method. The
Company generally creates cost centers on a field by field basis for oil and gas
activities in the Gulf of Mexico and Gulf of Thailand. Generally, the Company
establishes cost centers on the basis of an oil or gas trend or play for its oil
and gas activities onshore in the United States. The Company's DD&A expense for
the third quarter of 1998 was $24,921,000, a decrease of approximately 14% from
DD&A expense of $29,112,000 for the third quarter of 1997. The decrease in DD&A
expense for the third quarter of 1998, compared to the third quarter of 1997,
resulted primarily from decreased production of oil and natural gas from the
Company's properties that was only partially offset by an increase in the
Company's composite DD&A rate. The Company's DD&A expense for the first nine
months of 1998 was $83,739,000, an increase of approximately 10% from DD&A
expense of $75,989,000 for the first nine months of 1997. The increases in DD&A
expense for the first nine months of 1998, compared to the first nine months of
1997, resulted primarily from an increase in the Company's composite DD&A rate
that was only partially offset by a decrease in production of oil and natural
gas.

     The composite DD&A rate for all of the Company's producing fields for the
third quarter of 1998 was $1.08 per equivalent Mcf ($6.46 per equivalent
barrel), an increase of approximately 17% from a composite DD&A rate of $0.92
per equivalent Mcf ($5.53 per equivalent barrel) for the third quarter of 1997.
The composite DD&A rate for all of the Company's producing fields for the first
nine months of 1998 was $1.09 per equivalent Mcf ($6.54 per equivalent barrel),
an increase of approximately 20% from a composite DD&A rate of $0.91 per
equivalent Mcf ($5.46 per equivalent barrel) for the first nine months of 1997.
The increase in the composite DD&A rate for all of the Company's producing
fields for the third quarter and the first nine months of 1998, compared to the
third quarter and first nine months of 1997, resulted primarily from an
increased percentage of the Company's production coming from certain of the
Company's fields that have

DD&A rates that are higher than the Company's recent historical composite 
rate and a corresponding decrease in the percentage of the Company's 
production coming from fields that have DD&A rates that are lower than the 
Company's recent historical composite DD&A rate. The Company produced 
22,754,000 equivalent Mcf (3,792,000 equivalent barrels) during the third 
quarter of 1998, a decrease of approximately 26% from the 30,857,000 
equivalent Mcf (5,143,000 equivalent barrels) produced by the Company during 
the third quarter of 1997. The Company produced 75,781,000 equivalent Mcf 
(12,630,000 equivalent barrels) during the first nine months of 1998, a 
decrease of approximately 8% from the 82,036,000 equivalent Mcf (13,673,000 
equivalent barrels) produced by the Company during the first nine months of 
1997.

INTEREST

     INTEREST CHARGES

     The Company incurred interest charges for the third quarter of 1998 of
$6,236,000, an increase of approximately 5% from interest charges of $5,940,000
for the third quarter of 1997. Interest charges incurred by the Company for the
first nine months of 1998 were $17,513,000, an increase of approximately 11%
from interest charges of $15,771,000 for the first nine months of 1997. The
increase in interest charges for the third quarter and first nine months of
1998, compared to the third quarter and first nine months of 1997, resulted
primarily from an increase in the average amount of debt outstanding and, to a
lesser extent, the average interest rate charged on the Company's outstanding
debt. As of December 21, 1998, the Company was not a party to any interest rate
swap agreements.

     CAPITALIZED INTEREST

     Capitalized interest expense for the third quarter of 1998 was $2,476,000,
an increase of approximately 197% from capitalized interest expense of $833,000
for the third quarter of 1997. The increase in capitalized interest for the
third quarter of 1998, compared to the third quarter of 1997, resulted primarily
from an increase in the amount of capital expenditures subject to interest
capitalization during the third quarter of 1998 ($141,259,000), compared to the
third quarter of 1997 ($47,135,000), and from an increase in the computed rate
that the Company uses to apply to such capital expenditures to arrive at the
total amount of capitalized interest. A substantial percentage of the Company's
capitalized interest expense during the latter half of 1997 and the first nine
months of 1998 resulted from capitalization of interest related to such capital
expenditures for the development of the Benchamas Field in the Gulf of Thailand
and, to a lesser extent, several development projects in the Gulf of Mexico.
Capitalized interest expense for the first nine months of 1998 was $6,540,000,
an increase of approximately 89% from capitalized interest expense of $3,463,000
for the first nine months of 1997. The increase in capitalized interest for the
first nine months of 1998, compared to the first nine months of 1997, resulted
primarily from an increase in the amount of capital expenditures subject to
interest capitalization during the first nine months of 1998 ($122,414,000),
compared to the first nine months of 1997

($73,086,000), and from an increase in the computed rate that the Company 
uses to apply on such capital expenditures to arrive at the total amount of 
capitalized interest.

FOREIGN CURRENCY TRANSACTION GAIN (LOSS)

     The Company experienced foreign currency transaction gains of $760,000
during the third quarter and $953,000 during the first nine months of 1998,
compared to foreign currency transaction losses of $6,522,000 during the third
quarter and first nine months of 1997. The foreign currency transaction gains
and losses each resulted primarily from the fluctuation against the U.S. dollar
of cash and other monetary assets and liabilities denominated in Thai Baht that
were on the Company's subsidiary's financial statements during the respective
periods and, to a much lesser extent, the fluctuation of the Canadian dollar
against the U.S. dollar. In early July 1997, the government of the Kingdom of
Thailand announced that the value of the Baht would be set against the dollar
and other currencies under a "managed float" program arrangement. This led to a
substantial decline in value of the Thai Baht compared to the U.S. dollar,
resulting in the foreign currency transaction losses during the 1997 periods
presented. During the 1998 periods presented, the value of the Thai Baht has
generally strengthened against the U.S. dollar, resulting in corresponding
foreign currency transaction gains. However, the Company cannot predict what the
Thai Baht to dollar exchange rate may be in the future. Moreover, it is
anticipated that this exchange rate will remain volatile. As of December 15,
1998, the Company was not a party to any financial instrument that was intended
to constitute a foreign currency hedging arrangement.

INCOME TAX BENEFIT (EXPENSE)

     The Company experienced an income tax benefit for the third quarter of 1998
of $6,858,000, compared to income tax expense of $3,986,000 for the third
quarter of 1997. The Company experienced an income tax benefit for the first
nine months of 1998 of $9,052,000, compared to income tax expense of $15,694,000
for the first nine months of 1997. The income tax benefit for the third quarter
and first nine months of 1998, compared to the income tax expense for the third
quarter and first nine months of 1997, resulted primarily from a pre-tax loss
resulting from substantially lower revenues in the United States and the tax
benefit of accrued foreign losses from the Company's operations in the Kingdom
of Thailand.

LIQUIDITY AND CAPITAL RESOURCES  --

CASH FLOWS

     The Company's Condensed Consolidated Statement of Cash Flows for the nine
months ended September 30, 1998, reflects net cash provided by operating
activities of $70,446,000. In addition to net cash provided by operating
activities, the Company received net proceeds of $998,000 from the exercise of
stock options, $350,000 from the sale of certain non-strategic

properties, and had net borrowings of $83,354,000 under its revolving credit 
agreement and other senior debt facilities.

     During the first nine months of 1998, the Company invested $135,964,000 of
such cash flow in capital projects, retired a production payment obligation for
$15,246,000, spent $2,961,000 to purchase proved reserves, paid $3,327,000
($0.03 per share for each of the first three quarters of 1998) in cash dividends
to holders of the Company's common stock and paid a net amount of $621,000 in
miscellaneous other expenditures. As of September 30, 1998, the Company's cash
and cash investments were $17,422,000 and its long-term debt stood at
$381,854,000.

FUTURE CAPITAL REQUIREMENTS

     The Company's capital and exploration budget for 1998, which does not
include any amounts that 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 at $230,000,000. Substantially
all of the Company's 1998 capital and exploration budget was spent or incurred
during 1998. The Company currently anticipates that its available cash and cash
investments, cash provided by operating activities, funds available under its
revolving credit facility and an uncommitted line of credit and amounts that the
Company currently believes that it can obtain from external sources including
the issuance of new debt and convertible preferred securities, or asset sales,
will be sufficient to fund the Company's ongoing operating, interest and general
and administrative expenses, the remainder of its 1998 capital and exploration
budget, any currently anticipated costs associated with the Company's projects
during 1999, and future dividend payments at current levels. Subject to
favorable market conditions and other factors, the Company currently intends to
issue convertible preferred equity securities during 1999 to assist in funding
its future capital and exploration plans. The declaration of future dividends on
the Company's common stock will depend upon, among other things, the Company's
future earnings and financial condition, liquidity and capital requirements, its
ability to pay dividends under certain covenants contained in its debt
instruments, the general economic and regulatory climate and other factors
deemed relevant by the Company's Board of Directors.

YEAR 2000 READINESS DISCLOSURE

     Many computer software systems, as well as certain hardware and equipment
utilizing date-sensitive data, were structured to use a two-digit date field
meaning that they will not be able to properly recognize dates in the year 2000.
The Company is addressing this issue through a process that entails evaluation
of the Company's critical software and, to the extent possible, its hardware and
equipment to identify and assess Year 2000 issues and to remediate, replace or
establish alternative procedures addressing non-Year 2000 compliant systems,
hardware and equipment.

                     Management's Discussion and Analysis of
                  Financial Condition and Results of Operations


     The Company has substantially completed an inventory of its systems and
equipment including computer systems and business applications. Based upon this
review, the Company currently believes that all of its critical software and
computer hardware systems are either Year 2000 compliant or will be within the
next six months. The Company continues to inventory its equipment and facilities
to determine if they contain embedded date-sensitive technology. If problems are
discovered, remediation, replacement or alternative procedures for non-compliant
equipment and facilities will be undertaken on a business priority basis. This
process will continue and, depending upon the equipment and facilities, is
scheduled for completion during the first three quarters of 1999. As of
September 30, 1998, the Company had incurred approximately $50,000 in expenses
related to its Year 2000 compliance efforts. These costs are currently being
expensed as they are incurred. However, in certain instances the Company may
determine that replacing existing equipment may be more efficient, particularly
where additional functionality is available. These replacements may be
capitalized and therefore would reduce the estimated 1998 and 1999 expenses
associated with the Year 2000 issue. The Company currently expects total
out-of-pocket costs to become Year 2000 compliant to be less than $1,000,000.
The Company currently expects that such costs will not have a material adverse
effect on the Company's financial condition, operations or liquidity.

     The foregoing timetable and assessment of costs to become Year 2000
compliant reflect management's current best estimates. These estimates are based
on many assumptions, including assumptions about the cost, availability and
ability of resources to locate, remediate and modify affected systems, equipment
and facilities. Based upon its activities to date, the Company does not
currently believe that these factors will cause results to differ significantly
from those estimated. However, the Company cannot reasonably estimate the
potential impact on its financial condition and operations if key third parties
including, among others, suppliers, contractors, joint venture partners,
financial institutions, customers and governments do not become Year 2000
compliant on a timely basis. The Company is contacting many of these third
parties to determine whether they will be able to resolve in a timely fashion
their Year 2000 issues as they may affect the Company.

     In the event that the Company is unable to complete the remediation or
replacement of its critical systems, facilities and equipment, establish
alternative procedures in a timely manner, or if those with whom the Company
conducts business are unsuccessful in implementing timely solutions, Year 2000
issues could have a material adverse effect on the Company's liquidity and
results of operations. At this time, the potential effect in the event the
Company and/or third parties are unable to timely resolve their Year 2000
problems is not determinable; however, the Company currently believes that it
will be able to resolve its own Year 2000 issues in a timely manner.

     The disclosure set forth in this section is provided pursuant to Securities
Act Release No. 33-7558. As such it is protected as a forward-looking statement

AMENDED AND RESTATED CREDIT AGREEMENT

     Effective August 1, 1997, the Company entered into an amended and restated
Credit Agreement, which has subsequently been amended several times, most
recently on December 21, 1998. The Credit Agreement provides for a $250,000,000
revolving/term credit facility which will be fully revolving until July 1, 2000,
after which the balance will be due in eight quarterly term loan installments,
commencing October 31, 2000. A portion of the amount that may be borrowed under
the Credit Agreement (the "Primary Tranche") may not exceed a borrowing base
which is composed of domestic, Canadian and Thai properties. Generally, the
borrowing base is determined semi-annually by the lenders in accordance with the
Credit Agreement, based on the lenders' usual and customary criteria for oil and
gas transactions. As of December 21, 1998, the Company's total borrowing base
was set at $200,000,000, which amount cannot be reduced until after April 30,
1999. In addition, certain lenders that are parties to the Credit Agreement have
agreed to extend an additional $50,000,000 in credit (the "Secondary Tranche")
under the Credit Agreement without reference to the borrowing base limitations
of the Credit Agreement. The term of the Secondary Tranche is until the earlier
of April 30, 1999 or the completion of certain debt or equity offerings. The
Credit Agreement is governed by various financial and other covenants, including
requirements to maintain positive working capital (excluding current maturities
of debt) and a fixed charge coverage ratio, and limitations on indebtedness,
creation of liens, the prepayment of subordinated debt, the payment of
dividends, mergers and consolidations, investments and asset dispositions. Upon
the occurrence or declaration of certain events, the lenders would be entitled
to a security interest in the Company's domestic borrowing base properties. In
addition, the Company is prohibited from pledging borrowing base properties as
security for other debt. Borrowings under the Primary Tranche bear interest at a
rate based upon the percentage of the borrowing base that is being utilized,
ranging from a base (prime) rate or LIBOR plus 1.25% to a base rate plus 0.25%
or LIBOR plus 2.0%, at the Company's option. Borrowings under the Primary
Tranche currently bear interest at a base rate plus 0.25% or LIBOR plus 2.0%, at
the Company's option. Borrowings under the Secondary Tranche currently bear
interest at a base rate plus 0.75% or LIBOR plus 2.5% , at the Company's option.
A commitment fee on the unborrowed amount under the Primary Tranche is also
charged and is based upon the percentage of the borrowing base that is being
utilized, ranging from 0.25% to 0.375%. The commitment fee is currently 0.375%
per annum on unborrowed amounts under the Primary Tranche. As of December 21,
1998, there was $155,000,000 outstanding under the Primary Tranche and
$50,000,000 outstanding under the Secondary Tranche.

                           PART II. OTHER INFORMATION

Item 4.    Submission of Matters to a Vote of Security-Holders

          A special meeting of the stockholders of Arch was held in Ft. Worth,
     Texas on August 14, 1998. Proxies for the meeting were solicited pursuant
     to Regulation 14A under the Securities Exchange Act of 1934. Of a total of
     24,594,534 shares of Arch Common Stock outstanding and entitled to vote
     (including shares of Arch preferred stock on an "as converted basis"),
     18,577,341 were present at the meeting in person or by proxy, representing
     approximately 75.5% of the outstanding Arch Common Stock. In addition,
     holders of all 727,273 shares of Arch preferred stock that were outstanding
     and entitled to vote as a separate class on the merger were present at the
     meeting in person or by proxy.

          At the meeting, Arch stockholders approved the proposal to approve and
     adopt the Agreement and Plan of Merger, dated as of May 28, 1998, pursuant
     to which Arch would, upon consummation of the merger described therein, be
     the survivor and become a wholly-owned subsidiary of Pogo Producing
     Company. The vote tabulation (including shares of Arch's convertible
     preferred stock on an "as converted basis") with respect to the proposal
     was 18,262,906 shares of Arch common stock for, 261,948 shares against,
     52,487 abstentions and zero broker non-votes. In addition, all 727,273
     shares of Arch preferred stock, voting separately as a class, were voted in
     favor of the proposal. The merger was consummated on August 17, 1998,
     following the special meeting of Arch stockholders.

Item 5.    Other Information.

     In August 1998, a wholly owned subsidiary of the Company merged with 
Arch in a tax free, stock for stock, transaction through which Arch became a 
wholly owned subsidiary of the Company. The merger was initially accounted 
for as a pooling of interests which requires the financial results for all 
periods prior to the merger to be combined and restated as if the Company and 
Arch had always been combined. Consequently, the Company restated its 
consolidated financial statements for periods prior to the merger, including 
the third quarter and first nine months of 1997, and the first nine months of 
1998, to reflect the combined results of both the Company and Arch. A report 
on Form 10-Q for the periods ended September 30, 1998 was filed on that 
basis. The Company has recently concluded that, as a result of the current 
environment of low crude oil and natural gas prices, the Company must 
maintain maximum flexibility to address its cash flow needs, including the 
option of selling certain of the Company's assets. Under the current 
application of accounting principles, such transactions would preclude the 
pooling of interests method of accounting and require that the Company 
account for the merger using the purchase method of accounting. The Company 
is filing this amended report on Form 10-Q for the period ended September 30, 
1998 primarily for the purpose of restating the financial statements 
contained in such report and to make conforming changes to "Management's 
Discussion and

Analysis of Financial Condition and Results of Operations" to reflect the 
change from the pooling method of accounting to the purchase method of 
accounting for the Arch acquisition.

     On December 23, 1998, the Company issued the following news release:

     HOUSTON, TX -- December 23, 1998 -- Pogo Producing Company ("PPP" -- 
NYSE) responded to today's announcement that Rutherford-Moran Oil 
Corporation, a joint venture partner of Pogo's in the Gulf of Thailand, has 
agreed to be acquired by a unit of Chevron Corporation. The announcement made 
by Rutherford-Moran indicates that the acquisition is conditioned upon 
several things, including Chevron reaching certain agreements with Pogo 
regarding the B8/32 Concession in the Gulf of Thailand.

     Paul G. Van Wagenen, Pogo's Chairman and CEO, stated that Pogo has been 
contacted by Chevron in connection with Chevron's acquisition of 
Rutherford-Moran, but that Pogo would not speculate whether any agreement 
would be reached between Pogo and Chevron, or what the terms of any such 
agreement may be.

     Pogo Producing Company explores for, develops and produces oil and 
natural gas. Headquartered in Houston, Pogo owns various ownership interests

          may be, determination of the Borrowing Base, the Agent will propose 
          to the Lenders a Borrowing Base for acceptance by the Required 
          Borrowing Base Lenders.  If such Borrowing Base, as proposed by the 
          Agent is accepted by the Required Borrowing Base Lenders, then such 
          agreed Borrowing Base shall be communicated by the Agent to the 
          Borrower on or before (i) the next April 30th, in the case of a 
          Reserve Report and (ii) the next October 31st, in the case of an 
          Alternate Reserve Report, and shall remain in effect until the next 
          October 31st or April 30th; PROVIDED THAT if such proposed 
          Borrowing Base is not approved by the Required Borrowing Base 
          Lenders prior to the applicable date then, within thirty (30) days 
          following the applicable date, the Required Borrowing Base Lenders 
          will establish and agree to a Borrowing Base, and such amount will 
          be promptly communicated to the Borrower; PROVIDED THAT the then 
          current Borrowing Base shall remain in effect until the Borrower is 
          notified of the new Borrowing Base.  The new Borrowing Base shall 
          become effective as of the date that the Borrower receives 
          notification from the Agent of the new Borrowing Base.  The 
          Borrowing Base, as determined and established pursuant to this 
          SECTION 2.6(a) shall be subject, at all times after April 30, 1999, 
          to the redetermination of the then effective Borrowing Base as a 
          result of a Non-Standard Determination.

               (b)  With respect to a redetermination of the Borrowing Base 
          resulting from a Non-Standard Determination, the Agent or the 
          Required Lenders and the Borrower shall have the right, but not the 
          obligation on no more than one occasion during each six month 
          period ending on April 30th and October 31st, to notify the 
          Borrower or the Agent, respectively, of its intent to perform a 
          Non-Standard Determination of the Borrowing Base.  In connection 
          with the Non-Standard Determination and notwithstanding the 
          delivery of any new Alternate Reserve Report, the Agent shall 
          propose, and the Required Borrowing Base Lenders shall agree to and 
          approve, a new Borrowing Base which shall become effective upon 
          receipt by the Borrower of notice of such new Borrowing Base until 
          such new Borrowing Base may be redetermined as a result of a 
          scheduled semi-annual determination of the Borrowing Base pursuant 
          to SECTION 2.6(a).  In connection with any Non-Standard 
          Determination, the Borrower shall deliver promptly upon the request 
          of the Agent a new Alternate Reserve Report to the Agent."
