                             THE WISER OIL COMPANY
                                        
ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS

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

     Revenues for the second quarter of 1998 decreased $1.8 million or 10% from
the second quarter of 1997, due primarily to lower oil prices. Oil sales for the
second quarter of 1998 were $2.6 million lower than the second quarter of 1997
as the average price received for oil sales in the second quarter of 1998 was
$12.33 per barrel, down $4.99 per barrel or 29% from the second quarter of 1997.
Net oil production for the second quarter of 1998 was 592,000 barrels, up 3%
from 574,000 barrels in the second quarter of 1997 due primarily to increased
production from the Provost and Evi fields in Canada. Gas sales for the second
quarter of 1998 were $2.3 million higher than the second quarter of 1997 as the
average price received for gas sales was $1.96 per mcf, an increase of $0.19 per
mcf or 11% from the second quarter of 1997.  Net gas production for the second
quarter of 1998 was 3,768 MMCF, up 875 MMCF or 30% from the second quarter of
1997 due primarily to production from the Welder Ranch field in South Texas
which was acquired in June 1997.  During the second quarter of 1998, there were
no adjustments to oil and gas sales from the Company's hedging activities
compared to a reduction of $0.4 million in oil and gas sales in the second
quarter of 1997.  The Company liquidated its remaining portfolio of marketable
securities during 1997. Accordingly, there were no sales of marketable
securities in the second quarter of 1998, and there were no sales of marketable
securities in the second quarter of 1997.
 
     Production and operating expense for the second quarter of 1998 decreased
$0.5 million or 7% primarily as a result of cost cutting measures implemented at
the Maljamar and Wellman fields.  On a BOE basis (excluding 140 MMCF and 133
MMCF of gas purchased for resale during the second quarter of 1998 and 1997,
respectively), production and operating expense during the second quarter of
1998 decreased to $4.89 per BOE or 19% from $6.01 per BOE during the second
quarter of 1997.   Depreciation, depletion and amortization, ("DD&A") for the
second quarter of 1998, increased $1.6 million or 30% over the second quarter of
1997 due primarily to higher DD&A from the Maljamar field in New Mexico.
Exploration expense for the second quarter of 1998 was $3.7 million, up $0.2
million from the second quarter of 1997. General and administrative expense in
the second quarter of 1998 was comparable with the second quarter of 1997.
Interest expense during the second quarter of 1998 was $3.2 million or 54%
higher than the second quarter 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 $10 million of borrowings under the Credit Agreement in the second
quarter of 1998. The effective income tax rate during the second quarter of 1998
was 32% compared to 25% in the second quarter of 1997.
 
     The Company realized a net loss of $4.7 million and net loss per share of
$0.52 in the second quarter of 1998 compared to a net loss of $1.9 million and
net loss per share of $0.22 during the second quarter of 1997.  The Company's
Canadian operations incurred a pre-tax loss of $0.8 million during the second
quarter of 1998 compared to a pre-tax loss of $2.0 million during the second
quarter of 1997.

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

         COMPARISON OF SIX MONTHS ENDED JUNE 30, 1998 AND JUNE 30, 1997

     Revenues for the first half of 1998 decreased $10.0 million or 23% from the
first half of 1997, due primarily to lower oil prices. Oil sales for the first
half of 1998 were $6.5 million lower than the first half of 1997 as the average
price received for oil sales in the first half of 1998 was $13.27 per barrel,
down $5.30 per barrel or 29% from the first half of 1997.  Net oil production
for the first half of 1998 was 1,275,000 barrels, up 1% from 1,260,000 barrels
in the first half of 1997 due primarily to increased production from the Provost
and Evi fields in Canada. Gas sales for the first half of 1998 were $0.6 million
higher than the first half of 1997 as net gas production for the first half of
1998 was 7,198 MMCF, up 1,135 MMCF or 19% from the first half of 1997 due
primarily to production from the Welder Ranch field in South Texas which was
acquired in June 1997.  The average price received for gas sales during the
first half of 1998  was $1.96 per mcf, a decrease of $0.26 per mcf or 12% from
the first half of 1997. During the first half of 1998, there were no adjustments
to oil and gas sales from the Company's hedging activities compared to a
reduction of $1.8 million in oil and gas sales in the first half of 1997.  The
Company liquidated its remaining portfolio of marketable securities during 1997.
Accordingly, there were no sales of marketable securities in the first half of
1998 compared to $1.8 million in gain from sales of marketable securities in the
first half of 1997.
 
     Production and operating expense for the first half of 1998 decreased $1.1
million or 8% from the first half of 1997 primarily as a result of cost cutting
measures implemented at the Maljamar and Wellman fields and the sale of
properties in Michigan in the first quarter of 1997.  On a BOE basis (excluding
305 MMCF and 301 MMCF of gas purchased for resale during the first half of 1998
and 1997, respectively), production and operating expense during the first half
of 1998 decreased to $4.81 per BOE or 15% from $5.66 per BOE during the first
half of 1997. DD&A for the first half of 1998, increased $2.7 million or 24%
over the first half 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 half of 1998 was $7.0 million, up $2.9 million
from the first half of 1997 due primarily to higher seismic expense in the U.S.
General and administrative expense in the first half of 1998 was comparable with
the first half of 1997. Interest expense during the first half of 1998 was $6.4
million which was $3.0 million or 90% higher than the first half 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 $10 million of borrowings under the
Credit Agreement in the first half of 1998. The effective income tax rate during
the first half of 1998 was 30% compared to 25% in the first half of 1997.
 
     The Company realized a net loss of $8.2 million and net loss per share of
$0.92 in the first half of 1998 compared to net income of $4.2 million and
earnings per share of $0.47 during the first half of 1997.  The Company's
Canadian operations incurred a pre-tax loss of $1.5 million during the first
half of 1998 compared to a pre-tax loss of $2.9 million during the first half of
1997.

  COMPARISON OF SIX MONTHS ENDED JUNE 30, 1998 AND JUNE 30, 1997 (CONTINUED)

  Operating cash flows during the first half of 1998 were $4.0 million, down
$13.1 million from the first half of 1997 primarily as a result of decreased oil
sales combined with higher interest expense and a reduction in accounts payable.
Capital and exploration expenditures during the first half of 1998 were $28.7
million, down $12.1 million from $40.8 million during the first half of 1997.


YEAR 2000 ISSUE

The Company has assessed and continues to assess the impact of the "year 2000"
issue on its reporting systems and operations.  The "year 2000" 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 all its significant
computer systems and software will be year 2000 compliant during 1998.
Management does not estimate future expenditures related to the year 2000
exposure to be material.

NOTE 2. 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 two wholly owned
subidiaries 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.
