     Effective January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130 "Reporting Comprehensive Income"("SFAS 130") which

components in a full set of general purpose financial statements.  Comprehensive
income includes net income and other comprehensive income, which includes, but
is not limited to, unrealized gains for marketable securities and future
contracts, foreign currency translation adjustments and minimum pension
liability adjustments.  The impact of adopting SFAS No. 130 on the nine months

During 1998, the Financial Accounting Standards Board issued SFAS No. 131
"Disclosure about Segments of an Enterprise and Related Information", SFAS No.
132 "Employers' Disclosure about Pensions and Other Postretirement Benefits" and
SFAS No. 133 "Accounting for Derivative Instruments and Hedging Activities". The
new disclosure requirements of SFAS No. 131 and 132 are not expected to
materially change the Company's disclosures and SFAS No. 133 is not applicable
to the Company at this time.

NOTES TO FINANCIAL STATEMENTS (continued)

NOTE 3. SUMMARY OF GUARANTIES OF 9 1/2% SENIOR SUBORDINATED NOTES

     In May 1997, the Company issued $125 million aggregate principal amount of
its 9  1/2% Senior Subordinated Notes due 2007 pursuant to an offering exempt
from registration under the Securities Act of 1933.  The notes are unsecured
obligations of the Company, subordinated in right of payment to all existing and
any future senior indebtedness of the Company.  The notes rank pari passu with
any future senior subordinated indebtedness and senior to any future junior
subordinated indebtedness of the Company.  The notes are fully and
unconditionally guaranteed, jointly and severally, on an unsecured, senior
subordinated basis by certain wholly owned subsidiaries of the Company (the
"Subsidiary Guarantors").  At the time of the initial issuance of the notes,
Wiser Oil Delaware, Inc., The Wiser Marketing Company, Wiser Delaware LLC,
T.W.O.C., Inc. and The Wiser Oil Company of Canada were the Subsidiary
Guarantors (the "Initial Subsidiary Guarantors").  Except for five wholly owned
subsidiaries that are inconsequential to the Company on a consolidated basis,
the Initial Subsidiary Guarantors comprise all of the Company's direct and
indirect subsidiaries.

     Sections 13 and 15(d) of the Securities Exchange Act of 1934 require
presentation of the following unaudited summarized financial information of the
Subsidiary Guarantors.  The Company has not presented separate  financial
statements and other disclosures concerning each Subsidiary Guarantor because
such information is not material to investors.  There are no significant
contractual restrictions on distributions from each of the Subsidiary Guarantors
to the Company.

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

    COMPARISON OF QUARTERS ENDED SEPTEMBER 30, 1998 AND SEPTEMBER 30, 1997

     Revenues for the third quarter of 1998 decreased $3.2 million or 19% from
the third quarter of 1997, due primarily to lower oil prices. Oil sales for the
third quarter of 1998 were $3.2 million lower than the third quarter of 1997 as
the average price received for oil sales in the third quarter of 1998 was $11.96
per barrel, down $5.34 per barrel or 31% from the third quarter of 1997. Net oil
production for the third quarter of 1998 was 556,000 barrels, down 2% from
570,000 barrels in the third quarter of 1997. Gas sales for the third quarter of
1998 were $0.2 million higher than the third quarter of 1997. Net gas production
for the third quarter of 1998 was 3,516 MMCF, up 605 MMCF or 21% from the third
quarter of 1997 due primarily to additional production from wells drilled in
South Texas and new production from the Portage field in Canada. The average
price received for gas sales during the third quarter of 1998 was $1.69 per mcf,
a decrease of $0.28 per mcf or 14% from the third quarter of 1997. During the
third quarter of 1998, there were no adjustments to oil and gas sales from the
Company's hedging activities compared to a reduction of $0.3 million in oil and
gas sales in the third quarter of 1997. There were no sales of marketable
securities in the third quarter of 1998 and 1997, respectively.
 
     Production and operating expense for the third quarter of 1998 increased
$1.2 million or 18% primarily as a result of acquiring additional working
interests in the Wellman field.  On a BOE basis (excluding 137 MMCF and 162 MMCF
of gas purchased for resale during the third quarter of 1998 and 1997,
respectively), production and operating expense during the third quarter of 1998
increased to $6.33 per BOE or 7% from $5.91 per BOE during the third quarter of
1997.   Depreciation, depletion and amortization, ("DD&A") for the third quarter
of 1998, increased $1.2 million or 22% over the third quarter of 1997 due
primarily to higher DD&A from the Maljamar field in New Mexico.  Exploration
expense for the third quarter of 1998 was $3.5 million, up $1.3 million from the
third quarter of 1997 due primarily to higher dry hole expense in Peru and South
Texas. General and administrative expense in the third quarter of 1998 was $0.4
million higher than the third quarter of 1997 due to bad debt expense and
increased salaries and wages.  Interest expense during the third quarter of 1998
was $0.1 million or 3% higher than the third quarter of 1997 due to borrowings
under the Credit Agreement in the third quarter of 1998.  The effective income
tax rate during the third quarter of 1998 was 19% compared to 32% in the third
quarter of 1997.
 
     The Company realized a net loss of $8.2 million and net loss per share of
$0.91 in the third quarter of 1998 compared to a net loss of $1.9 million and
net loss per share of $0.21 during the third quarter of 1997.  The Company's
Canadian operations incurred a pre-tax loss of $1.5 million during the third
quarter of 1998 compared to a pre-tax loss of $0.2 million during the third
quarter of 1997.

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

   COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1998 AND SEPTEMBER 30, 1997

     Revenues for the first nine months of 1998 decreased $13.2 million or 22%
from the first nine months of 1997, due primarily to lower oil and gas prices.
Oil sales for the first nine months of 1998 were $9.7 million lower than the
first nine months of 1997 as the average price received for oil sales in the
first nine months of 1998 was $12.87 per barrel, down $5.30 per barrel or 29%
from the first nine months of 1997.  Net oil production for the first nine
months of 1998 was 1,831,000 barrels, up slightly from 1,830,000 barrels in the
first nine months of 1997. Gas sales for the first nine months of 1998 were $0.9
million higher than the first nine months of 1997 as net gas production for the
first nine months of 1998 was 10,714 MMCF, up 1,740 MMCF or 19% from the first
nine months of 1997 due primarily to additional production from wells drilled in
South Texas and new production from the Portage field in Canada. The average
price received for gas sales during the first nine months of 1998  was $1.87 per
mcf, a decrease of $0.27 per mcf or 13% from the first nine months of 1997.
During the first nine months of 1998, there were no adjustments to oil and gas
sales from the Company's hedging activities compared to a reduction of $2.1
million in oil and gas sales in the first nine months of 1997.  The Company
liquidated its remaining portfolio of marketable securities during 1997.
Accordingly, there were no sales of marketable securities in the first nine
months of 1998 compared to $1.8 million in gain from sales of marketable
securities in the first nine months of 1997.
 
     Production and operating expense for the first nine months of 1998 was
$20.0 million, up slightly from the first nine months of 1997 primarily as a
result of acquiring additional working interests in the Wellman field offset by
cost cutting measures implemented at the Maljamar and Wellman fields.  On a BOE
basis (excluding 442 MMCF and 463 MMCF of gas purchased for resale during the
first nine months of 1998 and 1997, respectively), production and operating
expense during the first nine months of 1998 decreased to $5.29 per BOE from
$5.74 per BOE during the first nine months of 1997. DD&A for the first nine
months of 1998, increased $3.8 million or 23% over the first nine months of 1997
due primarily to higher DD&A from the Maljamar field in New Mexico and from the
South Texas properties acquired in June 1997. Exploration expense for the first
nine months of 1998 was $10.5 million, up $4.2 million from the first nine
months of 1997 due primarily to higher dry hole and seismic expense. General and
administrative expense in the first nine months of 1998 was $0.4 million higher
than the first nine months of 1997 due to bad debt expense and increased
salaries and wages. Interest expense during the first nine months of 1998 was
$9.8 million, up $3.1 million or 47% from the first nine months of 1997 due to
the increase in long term debt associated with the issuance of $125 million of
Senior Subordinated Notes in May 1997 and borrowings under the Credit Agreement
in the first nine months of 1998. The effective income tax rate during the first
nine months of 1998 was 25% compared to 19% in the first nine months of 1997.
 
     The Company realized a net loss of $16.4 million and net loss per share of
$1.83 in the first nine months of 1998 compared to net income of $2.3 million
and earnings per share of $0.26 during the first nine months of 1997.  The
Company's Canadian operations incurred a pre-tax loss of $3.0 million

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

   COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1998 AND SEPTEMBER 30, 1997
                                  (CONTINUED)

during the first nine months of 1998 compared to a pre-tax loss of $3.2 million
during the first nine months of 1997.

     Operating cash flows during the first nine months of 1998 were $3.5
million, down $22.2 million from the first nine months of 1997 primarily as a
result of decreased oil and gas sales combined with higher interest expense and
a reduction in accounts payable.  Capital and exploration expenditures during
the first nine months of 1998 were $37.0 million, down $21.3 million from $58.3
million during the first nine months of 1997. In light of the reduced cash flows
received in 1998 compared to 1997, the Company has reduced its capital and
exploration budget for 1998 by approximately $10 million. On a cash basis, the
Company paid $0.2 million and $6.2 million in interest expense in the third
quarter of 1998 and nine months ended September 30, 1998, respectively. No
income taxes were paid in the third quarter of 1998 or the nine months ended
September 30, 1998.

     Effective September 30, 1998 the Credit Agreement was amended to relax
certain financial ratios related to Consolidated Funded Debt and Consolidated
Interest Coverage from September 30, 1998 through March 30,1999. In addition,
the Borrowing Base under the Credit Agreement was reduced from $80 million to
$25 million effective September 30, 1998.

     On November 10, 1998, the Company borrowed $6.0 million under the Credit
Agreement to refinance certain short term obligations and for general corporate
purposes.  Accordingly, $4.5 million of short term obligations were classified
as long term debt at September 30, 1998.

YEAR 2000 ISSUE

The Company has assessed and continues to assess the impact of the year 2000
("Y2K") issue on its reporting systems and operations.  The Y2K issue exists
because many computer systems and applications currently use two-digit date
fields to designate a year.  As the century date occurs, two-digit date systems
will recognize the year 2000 as 1900 or not at all.  This inability to recognize
the year 2000 may cause systems to process critical financial and operational
information incorrectly.  The Company anticipates that its significant computer
systems and software used in both office and field locations will be Y2K
compliant during 1998.  Management does not estimate future expenditures related
to the Y2K issue to be material.
