Item 1. Business

General

The Wiser Oil Company (the "Company" or "Wiser") is an independent oil and gas
exploration and production company operating in Texas, New Mexico, the Gulf
Coast and Alberta, Canada. Historically, the Company's growth has been
attributed primarily to acquisition, development, exploitation and, to a lesser
extent, exploration activities. The Company's two largest properties,
representing 50% of total proved reserves, are oil exploitation projects in the
Permian Basin which were acquired by Wiser between 1992 and 1996. The Company's
total proved reserves at December 31, 2000 are 37.2 MMBOE, having a pre-tax
present value of $229.1 million based on constant prices of $22.05 per barrel
for oil and $3.75 per Mcf for gas and discounted at 10%. The estimated present
value of the Company's proved reserves disclosed elsewhere in this Form 10-K is
based on year-end prices of $25.18 per barrel of oil and $9.72 per Mcf of gas.
Wiser's proved reserves at December 31, 2000 were 96% developed, with oil and
NGL's comprising 66% and natural gas comprising 34% of total reserves.
Approximately 79% of the Company's proved reserves are located in the U.S. and
21% are located in Canada. Over the past five years, the Company has replaced
93% of its production through a combination of acquisition, exploration,
development and exploitation activities.

History

In 1905, Clinton B. Wiser pooled some oil leases and founded The Wiser Oil
Company. The Company began operations in Kentucky in 1917 and maintained its
headquarters in Sistersville, West Virginia, until 1991. The Company moved its
headquarters to Dallas, Texas in 1991 and over the next five years Wiser
expanded operations by acquiring and operating properties in the Permian Basin
in West Texas and Southeast New Mexico and in Alberta, Canada. In 1999, the
Company sold non-strategic properties in Appalachia and began focusing its
exploration and production operations primarily in Texas, New Mexico, the Gulf
Coast and Alberta, Canada.

In May 2000, the Company completed a corporate restructuring and appointed
George K. Hickox, Jr. as the new CEO. As part of the corporate restructuring,
Wiser received a $15 million capital infusion through the sale of convertible
preferred stock.

Strategy

Over the past few years, the Company has focused on growing reserves primarily
through the acquisition of proved properties with exploitation and exploration
potential. Although Wiser has pursued numerous acquisition opportunities, the
Company has not made any significant acquisitions of properties since the
purchase of properties in South Texas in 1997 for approximately $20 million. In
2000, the Company funded its capital expenditures with cash flow from operations
and replaced 119% of its production and ended the year 2000 with $35 million in
cash. During 2001, the Company plans to focus on acquisition opportunities in
the Gulf Coast and in Canada. In addition, the Company plans to increase its
exposure to quality exploration projects in South Texas and the Gulf of Mexico
by entering into joint ventures. Accordingly, the Company will be participating
in a greater number of exploration projects in 2001 than in the past few years.

The Company's principal executive offices are located at 8115 Preston Road,
Suite 400, Dallas, Texas 75225, and its telephone number is (214) 265-0080.

Certain oil and gas industry terms used herein are defined in the "Glossary of
Oil and Gas Terms" appearing at the end of this Item 1.

Permian Basin

Maljamar. The Company's Maljamar properties are situated in Southeast New
Mexico. At December 31, 2000, the Maljamar properties contained 9.9 MMBOE of
proved reserves, which represented 27% of the Company's total proved reserves
and 13% of the Company's Present Value of total proved reserves.

The Maljamar properties consist primarily of three oil producing units acquired
by the Company in separate transactions between 1992 and 1996: the Maljamar
Grayburg and Caprock Maljamar Units, both of which are in Lea County, New
Mexico, and the Skelly Unit in Eddy County, New Mexico. The Maljamar Grayburg
Unit produces from the Grayburg and San Andres formations at depths ranging from
3,800 to 4,500 feet, and the Caprock Maljamar Unit produces from the same
formations at depths ranging from 4,000 to 5,000 feet. The Skelly Unit is
located approximately five miles west of the two Lea County units and produces
from the Seven Rivers, Grayburg and San Andres formations at depths ranging from
2,100 to 4,000 feet. The Company has a 100% working interest in each of these
units, which, along with some smaller adjacent properties, have been combined
into a single large-scale waterflood project encompassing approximately 14,000
gross leasehold acres.

Exploitation efforts at the project are essentially complete and included
conversion of existing wells to injection wells and the drilling of infill
development wells on 20-acre spacing to create 40-acre five-spot water injection
patterns.  At December 31, 2000, the project included 227 producing wells and
159 water injection wells, virtually all of which were operated by the Company.

The Company's net production from the Maljamar properties averaged 1,449 Bbls of
oil, 68 Bbls of NGLs and 559 Mcf of natural gas per day in 2000.  The Company's
cumulative net production from the Maljamar properties since acquired by the
Company has been 4,293 MBbls of oil and 2.1 Bcf of natural gas through December
31, 2000.

                                                           The Wiser Oil Company


Wellman Unit. In 1993 the Company acquired a 62% working interest in and became
operator of the Wellman Unit in Terry County, Texas, located in the northwestern
edge of the Horseshoe Atoll. During 1998 and 1999, the Company acquired an
additional 28% and 5% working interest, respectively, in the Wellman Unit which
increased the Company's working interest to 95% as of December 31, 2000. At
December 31, 2000, the Company's Wellman property contained 8.6 MMBOE of proved
reserves, which represented 23% of the Company's total proved reserves and 6% of
the Company's Present Value of total proved reserves.

The Company owns 2,280 gross (2,165 net) leasehold acres in the Wellman Unit.
The Wellman Unit produces oil from the Wolfcamp Reef formation at depths ranging
from 9,100 to 10,000 feet through the injection of water and CO2 into the
reservoir. Water injection at the unit began in 1979, and CO2 injection began in
1983. The unit also includes a gas processing plant, which processes wellhead
gas produced from the unit. Wiser's interest in this plant is proportionate to
its working interest in the Wellman Unit. Processing at the plant involves
subjecting the wellhead gas to high pressure and low temperature treatments that
cause the gas to separate into various products, including NGLs, residual
natural gas and CO2. The NGLs and residual natural gas are sold to pipeline
companies, and the CO2 is reinjected into the unit's reservoir. At December 31,
2000, the unit included 16 productive wells, six water injection wells, three
CO2 injection wells and three water disposal wells, all of which were operated
by the Company.

The Company's net production from the Wellman Unit averaged 564 Bbls of oil, 293
Bbls of NGLs and 112 Mcf of natural gas per day in 2000. The Company's
cumulative net production from the unit since acquired by the Company has been
2,252 MBbls of oil, 846 MBbls of NGLs and 523 MMcf of natural gas through
December 31, 2000.

In 1995 the Company began reconditioning the gas processing plant at the Wellman
Unit to enhance the extraction of NGLs and residual natural gas from the
wellhead gas. The Company completed the reconditioning project in June 1995 at a
total cost of approximately $6.0 million. For the year ended December 31, 2000,
the gas plant processed an average of 30 MMcf of gross natural gas and CO2 per
day and recovered an average of 355 Bbls of NGLs and 134 Mcf of residual natural
gas per day. The plant currently operates at 95% of its maximum capacity of 35
MMcf of gas per day.

Dimmitt/Slash Ranch Fields. The Company's Dimmitt/Slash Ranch properties are
situated in Loving County, Texas, 80 miles west of Midland, Texas. At December
31, 2000, the Dimmitt/Slash Ranch properties contained 4.0 MMBOE of proved
reserves, which represented 11% of the Company's total proved reserves and 14%
of the Company's Present Value of total proved reserves.

The Company owns 6,543 gross (5,874 net) leasehold acres in the Dimmitt/Slash
Ranch Field. The Company acquired its initial interest in and became operator of
the field in 1993. The Dimmitt Field produces oil and gas from the Cherry Canyon
and Bell Canyon formations at depths ranging from 4,700 to 6,700 feet. The Slash
Ranch Field is a natural gas field that underlies the Dimmitt Field. The Slash
Ranch Field produces from the Atoka, Fusselman and Ellenburger formations at
depths ranging from 15,000 to 20,000 feet. At December 31, 2000, the
Dimmitt/Slash Ranch Field included 79 producing wells, all of which were
operated by the Company. The Company's average working interest in these wells
is 98%.

The Company's net production from the Dimmitt/Slash Ranch properties averaged
376 Bbls of oil and 2,984 Mcf of natural gas per day in 2000. The Company's
cumulative net production from the properties since acquired by the Company has
been 896 MBbls of oil and 7.2 Bcf of natural gas through December 31, 2000.

                                                           The Wiser Oil Company


San Juan Basin

The Company's San Juan Basin properties are located in Rio Arriba County in
northwestern New Mexico. At December 31, 2000, the San Juan Basin properties
contained 4.1 MMBOE of proved reserves, which represented 11% of the Company's
total proved reserves and 21% of the Company's Present Value of total proved
reserves. The Company owns 10,800 gross (6,159 net) leasehold acres in the San
Juan Basin. In the 1950's, the Company's average 48% working interest in most of
the acreage was contributed in connection with a unitization of the wells in the
San Juan Basin fields, resulting in the ownership by the Company of small non-
operated working interests in several large units. At December 31, 2000, the
Company owned working interests in approximately 2,560 producing gas wells in
the San Juan Basin. These working interests average approximately 1.8%. The
Company's San Juan Basin properties produce from multiple formations ranging
from depths of 3,000 feet to 8,000 feet.

The Company's net production from these properties averaged 7,296 Mcf of natural
gas, 58 Bbls of oil and 16 Bbls of NGLs per day in 2000. The Company expects
that future development of the properties will depend on natural gas prices, and
that its share of the costs of any such future development activities will not
be significant.

Other U.S. Properties

The Company's other United States properties include properties located in the
West Texas, New Mexico and the Gulf Coast onshore region.

Canada

In June 1994, Wiser established an important new core area with the completion
of a $52.0 million acquisition of Canadian oil and gas properties from Eagle
Resources, Ltd. The purchase included 7.2 MMBOE of proved reserves,
approximately 127,000 net undeveloped acres, seven exploration prospects and an
existing staff of 23 persons. At December 31, 2000, the Company's Canadian
properties contained 8.0 MMBOE of proved reserves, which represented 21% of the
Company's total proved reserves and 29% of the Present Value of the Company's
total proved reserves.

Exploration Activities

United States

The objective of Wiser's domestic exploration program is to generate exploration
and exploitation drilling opportunities that have the potential of replacing
produced reserves and providing a vehicle of growth for the Company. In 2000,
Wiser drilled or participated in 12 gross (4.0 net) U.S. exploration wells,
compared with 8 gross (3.7 net) wells in 1999, spending $4.3 million in 2000 and
$1.1 million in 1999 on U.S. exploration. Of the 12 gross wells drilled by the
Company in 2000, 8 were completed as oil or gas wells, and 4 were unsuccessful,
which yields a 67% U.S. exploration success rate in 2000. In 2001, Wiser plans
to drill or participate in approximately 16 gross wells in the U.S. and the
Company has budgeted approximately $10.8 million for its 2001 U.S. exploration
program.

The Company is currently focusing its U.S. exploration activities in the
following geographical areas:

South Texas. At the Roche Ranch prospect in Refugio County, the Company drilled
3 gross wells in 2000 of which 2 were completed as new gas field discoveries.
The Company operates and has a 40% working interest in the Roche Ranch prospect.
The primary objectives are Frio gas sands at a depth of 5,000 to 7,000 feet,
which are defined utilizing proprietary 3-D seismic surveys. The Company plans
to drill 3 exploration wells in the Roche Ranch prospect in 2001.

Wiser also operates and has a 40% working interest in the Fitzsimmons prospect
in Jim Wells County. Utilizing proprietary 3-D seismic surveys, the Company has
identified several Frio and Yegua gas sand objectives at depths of 5,000 to
8,500 feet, respectively. In 2000, the Company drilled and completed the Goldapp
#1 as a new gas field discovery and the Company plans to drill another well at
the Fitzsimmons prospect in 2001.

At the Menefee prospect in Wharton County, Wiser drilled 3 gross wells in 2000
which target high-pressured Yegua gas sands at depths of 7,800 to 8,700 feet
that have been defined using 3-D seismic surveys. The Kathleen Appling GU #1 and
the Stovall # 1 were completed as gas wells in 2000 and the Stovall #2 was a dry
hole. Wiser has a 30% working interest in the Menefee prospect and is evaluating
this prospect for further drilling in 2001.

                                                           The Wiser Oil Company


Gulf Coast. At the Little Crow prospect in Wilkinson County, Mississippi, the
T.O.Sessions #1 exploration well was drilled and completed as an oil well in
2000. The Company subsequently sold its interest in the T. O. Sessions #1 well
and is evaluating this prospect for further drilling in 2001. Wiser has a 50%
non-operating working interest in this prospect.

At the Castleberry prospect in Conecuh County, Alabama, the McMillan # 1 was
drilled as a dry hole in 2000. The Company plans to drill another well on the
Castleberry prospect in 2001 where Wiser operates and has a 50% working
interest.

The Company has recently entered into exploration agreements with several other
companies to participate in various Gulf Coast prospects in 2001 that will be
operated by other companies or Wiser, depending on the prospect. The Company
anticipates that fewer U.S. exploration prospects will be generated by the
Company in 2001 than in prior years.


Canada

Wiser focuses its Canadian exploration activities in specific regions within the
Western Canadian Sedimentary Basin in close proximity to known producing
horizons where the potential for significant reserves exists. The Company's
technical personnel have considerable experience in this focus area. During
2000, the Company drilled or participated in 7 gross (3.8 net) exploratory wells
of which 4 were completed as successful oil or gas wells and 3 were dry holes.
The Company spent $6.0 million on exploration in Canada in 2000, compared to
$3.6 million in 1999, and has budgeted $4.8 million for its 2001 Canadian
exploration program.

In 2000, the Company successfully completed the Wiser/Mobil Wild River 2-32
exploratory well at the Wild River prospect. The Wild River 2-32 was tested in
January 2001 at an average rate of 1.6 MMcf per day of sour gas. The Company
plans to tie this well into a pipeline in 2001 and evaluate the Wild River
prospect for further drilling in 2001. Wiser operates and has a 50% working
interest in the well.

International

The Company did not participate in any international exploration activity in
2000 and currently has no plans to participate in future international
exploration activities.

Marketing of Production

The Company markets its production of oil, natural gas and NGLs to a variety of
purchasers, including large refiners and resellers, pipeline affiliate
marketers, independent marketers, utilities and industrial end-users. To help
manage the impact of potential price declines, Wiser has developed a portfolio
of long- and short-term contracts with prices that are either fixed or related
to market conditions in varying degrees. Most of the Company's production is
sold pursuant to contracts that provide for market-related pricing for the areas
in which the production is located.

During the year ended December 31, 2000, revenues from the sale of production to
Highland Energy Company, Nexen Inc. and EOTT Energy Operating Ltd. represented
approximately 42%, 24% and 13%, respectively, of the Company's total oil and gas
revenues.  The Company believes it would be able to locate alternate purchasers
in the event of the loss of any one or more of these purchasers, and that any
such loss would not have a material adverse effect on the Company's financial
condition or results of operations.

                                                           The Wiser Oil Company


Crude Oil. The Company sells its crude oil and condensate to various refiners
and resellers in the United States and Canada at posting-related and spot-
related prices that also depend on factors such as well location, production
volume and product quality. The Company typically sells its crude oil and
condensate production at or near the well site, although in some cases it is
gathered by the Company or others and delivered to a central point of sale. The
Company's crude oil and condensate production is transported by truck or by
pipeline and is typically committed to arrangements having a term of one year or
less. The Company has not engaged in crude oil trading activities. Revenue from
the sale of crude oil and condensate totaled $32.7 million for the year ended
December 31, 2000 and represented 49% of the Company's total oil and gas
revenues for 2000.

From time to time, the Company enters into crude oil and natural gas price
hedges to reduce its exposure to commodity price fluctuation. See Item 7A -
"Quantitative and Qualitative Disclosures about Market Risk - Commodity Price
Risk" and Note 1 to the Company's Consolidated Financial Statements included
elsewhere in this Report.

Natural Gas. The Company sells its produced natural gas and gathered gas to
utilities, marketers, processor/resellers and industrial end-users primarily
under market-sensitive, long-term contracts or daily, monthly or multi-month
spot agreements. An insignificant amount of the Company's natural gas is
committed to long-term, fixed-price sales agreements. To accomplish the delivery
and sale of certain of its natural gas, the Company has entered into long-term
agreements with various natural gas gatherers that deliver its gas to points of
sale on major transmission pipelines.

The Company believes that it has sufficient production from its properties, and
from those of others tied to its gathering and transportation system, to meet
the Company's delivery obligations under its existing natural gas sales
contracts.

NGLs. From its natural gas processing plants in West Texas, the Company sells
NGLs to independent marketers for resale. A direct pipeline connection to the
Texas Gulf Coast market area facilitates the sale of NGLs from the Company's
Wellman Unit, and enables the Company to receive prices that are representative
of the daily market value of NGLs on the Texas Gulf Coast, less transportation
and fractionation costs. The Company's average price in 2000 for NGLs sold from
Company-operated plants or under processing agreements with others was $22.19
per Bbl. Prices for NGLs attributable to natural gas sold to plants operated by
others are generally included in the prices reported by the Company for the sale
of its natural gas.

Price Considerations. Crude oil prices are established in a highly liquid,
international market, with average crude oil prices received by the Company
generally fluctuating with changes in the futures price established on the NYMEX
for West Texas Intermediate Crude Oil ("NYMEX-WTI"). The average crude oil price
per Bbl received by the Company in 2000 was $21.69. The average NYMEX-WTI
closing price per Bbl for 2000 was $30.12.

Natural gas prices in each of the geographical areas in which the Company
operates are closely tied to established price indices which are heavily
influenced by national and regional supply and demand factors and the futures
price per MMBtu for natural gas delivered at Henry Hub, Louisiana established on
the NYMEX ("NYMEX-Henry Hub").  At times, these indices correlate closely with
the NYMEX-Henry Hub price, but often there are significant variances between the
NYMEX-Henry Hub price and the indices used to price the Company's natural gas.
Average natural gas prices received by Wiser in each of its operating areas
generally fluctuate with changes in these established indices.  The average
natural gas price per Mcf received by the Company in 2000 was $3.31.  The
average NYMEX-Henry Hub price per MMBtu for 2000 was $3.91, computed by
averaging the closing price on the last three trading days of each month of the
forward prompt month NYMEX natural gas futures contract price applicable to each
month in 2000.  The average natural gas price received by the Company in 2000
was lower than such 2000 NYMEX-Henry Hub price as a result of pricing
differentials determined by the location of the Company's natural gas production
relative to the Henry Hub trading point and lower natural gas prices generally
applicable to Canadian natural gas production relative to U.S. production.

(1) The Standardized Measure of Discounted Future Net Cash Flows prepared by the
    Company represents the present value (using an annual discount rate of 10%)
    of estimated future net revenues from the production of proved reserves,
    after giving effect to income taxes.  See the Supplemental Financial
    Information attached to the Consolidated Financial Statements of the Company
    included elsewhere in this Report for additional information regarding the
    disclosure of the Standardized Measure information in accordance with the
    provisions of Statement of Financial Accounting Standards ("SFAS") No. 69,
    "Disclosures about Oil and Gas Producing Activities."

                                                           The Wiser Oil Company

All information set forth in this Report relating to the Company's proved
reserves, estimated future net revenues and Present Values is taken from reports
prepared by DeGolyer and MacNaughton (with respect to the Company's United
States properties) and Gilbert Lausten Jung Associates Ltd. (with respect to the
Company's Canadian properties), each of which is a firm of independent petroleum
engineers.  The estimates of these engineers were based upon review of
production histories and other geological, economic, ownership and engineering
data provided by the Company. No reports on the Company's reserves have been
filed with any federal agency.  In accordance with guidelines of the Securities
and Exchange Commission ("SEC"), the Company's estimates of proved reserves and
the future net revenues from which Present Values are derived are made using
year end oil and gas sales prices held constant throughout the life of the
properties (except to the extent a contract specifically provides otherwise).  A
decline in prices relative to year end 2000 could cause a significant decline in
the Present Value attributable to the Company's proved reserves at December 31,
2000.  Operating costs, development costs and certain production-related taxes
were deducted in arriving at estimated future net revenues, but such costs do
not include debt service, general and administrative expenses and income taxes.

There are numerous uncertainties inherent in estimating oil and gas reserves and
their values, including many factors beyond the Company's control.  The reserve
data set forth in this Report represents estimates only.  Reservoir engineering
is a subjective process of estimating the sizes of underground accumulations of
oil and gas that cannot be measured in an exact manner.  The accuracy of any
reserve estimate is a function of the quality of available data, engineering and
geological interpretation, and judgment. As a result, estimates of different
engineers, including those used by the Company, may vary.  In addition,
estimates of reserves are subject to revision based upon actual production,
results of future development, exploitation and exploration activities,
prevailing oil and gas prices, operating costs and other factors, which
revisions may be material.  Accordingly, reserve estimates are often  different
from the quantities of oil and gas that are ultimately recovered and are highly
dependent upon the accuracy of the assumptions upon which they are based.  There
can be no assurance that these estimates are accurate predictions of the
Company's oil and gas reserves or their values.  Estimates with respect to
proved reserves that may be developed and produced in the future are often based
upon volumetric calculations and upon analogy to similar types of reserves
rather than actual production history.  Estimates based on these methods are
generally less reliable than those based on actual production history.
Subsequent evaluation of the same reserves based upon production history will
result in variations, which may be substantial, in the estimated reserves.

    average approximately 1.8%.

Acreage

The following table sets forth the Company's undeveloped and developed gross and
net leasehold acreage at December 31, 2000.  Undeveloped acreage includes leased
acres on which wells have not been drilled or completed to a point that would
permit the production of commercial quantities of oil and gas, regardless of
whether or not such acreage contains proved reserves.

(1) Excluded is acreage in which the Company's interest is limited to a mineral
    or royalty interest. At December 31, 2000, the Company held mineral or
    royalty interests in 1,108 gross (596 net) developed acres.

All the leases for the undeveloped acreage summarized in the preceding table
will expire at the end of their respective primary terms unless prior to that
date the existing leases are renewed or production has been obtained from the
acreage subject to the lease, in which event the lease will remain in effect
until the cessation of production. The following table sets forth the minimum

As is customary in the industry, the Company generally acquires oil and gas
acreage without any warranty of title except as to claims made by, through or
under the transferor.  Although the Company has title to developed acreage
examined prior to acquisition in those cases in which the economic significance
of the acreage justifies the cost, there can be no assurance that losses will
not result from title defects or from defects in the assignment of leasehold
rights. In many instances, title opinions may not be obtained if in the
Company's judgment it would be uneconomical or impractical to do so.

Operations

The Company generally seeks to be named as operator for wells in which it has
acquired a significant interest, although, as is common in the industry, this
typically occurs only when the Company owns the major portion of the working
interest in a particular well or field.  At December 31, 2000, the Company
operated 98% of its properties in the Permian Basin, comprising approximately
61% of the Company's total proved reserves, including Maljamar (222 gross
wells), Wellman (16 gross wells) and Dimmitt/Slash Ranch (79 gross wells). At
December 31, 2000, the Company also operated 124 (out of a total of 315) gross
wells on its Canadian properties.

                                                         The Wiser Oil Company

As operator, the Company is able to exercise substantial influence over the
development and enhancement of a well and to supervise operation and maintenance
activities on a daily basis. The Company does not conduct the actual drilling of
wells on properties for which it acts as operator, but engages independent
contractors who are supervised by the Company. The Company employs petroleum
engineers, geologists and other operations and production specialists who strive
to improve production rates, increase reserves and/or lower the cost of
operating its oil and gas properties.

Oil and gas properties are customarily operated under the terms of a joint
operating agreement, which provides for reimbursement of the operator's direct
expenses and monthly per-well supervision fees. Per-well supervision fees vary
widely depending on the geographic location and producing formation of the well,
whether the well produces oil or gas and other factors. Such fees received by
the Company in 2000 ranged from $99 to $980 per well per month.

Competition

The oil and gas industry is highly competitive. The Company encounters
competition from other oil and gas companies in all areas of its operations,
including the acquisition of producing properties. The Company's competitors
include major integrated oil and gas companies and numerous independent oil and
gas companies, individuals and drilling and income programs. Many of its
competitors are large, well established companies with substantially larger
operating staffs and greater capital resources than the Company. Such companies
may be able to pay more for productive oil and gas properties and exploratory
prospects and to define, evaluate, bid for and purchase a greater number of
properties and prospects than the Company's financial or human resources permit.
The Company's ability to acquire additional properties and to discover reserves
in the future will depend upon its ability to evaluate and select suitable
properties and to consummate transactions in a highly competitive environment.

Drilling and Operating Risks

Drilling activities are subject to many risks, including the risk that no
commercially productive oil or gas reservoirs will be encountered. There can be
no assurance that new wells drilled by the Company will be productive or that
the Company will recover all or any portion of its investment. Drilling for oil
and gas may involve unprofitable efforts, not only from dry wells, but also from
wells that are productive but do not produce sufficient net revenues to return a
profit after drilling, operating and other costs. The cost of drilling,
completing and operating wells is often uncertain. The Company's drilling
operations may be curtailed, delayed or canceled as a result of a variety of
factors, many of which are beyond its control, including economic conditions,
mechanical problems, pressure or irregularities in formations, title problems,
weather conditions, compliance with governmental requirements and shortages in
or delays in the delivery of equipment and services. Such equipment shortages
and delays sometimes involve drilling rigs, especially in Canada, where weather
conditions result in a short drilling season, causing a high demand for rigs by
a large number of companies during a relatively short period of time. The
Company's future drilling activities may not be successful. Lack of drilling
success could have a material adverse effect on the Company's financial
condition and results of operations.

In addition, the Company's use of 3-D seismic requires greater pre-drilling
expenditures than traditional drilling strategies. Although the Company believes
that its use of 3-D seismic will increase the probability of success of its
exploratory wells and should reduce average finding costs through the
elimination of prospects that might otherwise be drilled solely on the basis of
2-D seismic and other traditional methods, unsuccessful wells are likely to
occur.

The Company's operations are subject to all the hazards and risks normally
incident to the development, exploitation, production and transportation of, and
the exploration for, oil and gas, including unusual or unexpected geologic
formations, pressures, down-hole fires, mechanical failures, blowouts,
cratering, explosions, uncontrollable flows of oil, gas or well fluids and
pollution and other environmental risks. These hazards could result in
substantial losses to the Company due to injury and loss of life, severe damage
to and destruction of property and equipment, pollution and other environmental
damage and suspension of operations. The Company maintains comprehensive

                                                           The Wiser Oil Company

insurance coverage, including a $2.0 million general liability insurance policy
and a $30.0 million excess liability policy. The Company believes that its
insurance is adequate and customary for companies of a similar size engaged in
comparable operations, but losses could occur for uninsurable or uninsured risks
or in amounts in excess of existing insurance coverage.

Title to Properties

The Company's land department and contract land professionals have reviewed
title records or other title review materials relating to substantially all of
its producing properties. The title investigation performed by the Company prior
to acquiring undeveloped properties is thorough, but less rigorous than that
conducted prior to drilling, consistent with industry standards. The Company
believes it has satisfactory title to all its producing properties in accordance
with standards generally accepted in the oil and gas industry. The Company's
properties are subject to customary royalty interests, liens incident to
operating agreements, liens for current taxes and other inchoate burdens which
the Company believes do not materially interfere with the use of or affect the
value of such properties. At December 31, 2000, the Company's leaseholds for
approximately 35% of its net acreage were being kept in force by virtue of
production on that acreage in paying quantities. The remaining net acreage was
held by lease rentals and similar provisions and requires production in paying
quantities prior to expiration of various time periods to avoid lease
termination.

The Company expects to make acquisitions of oil and gas properties from time to
time. In making an acquisition, the Company generally focuses most of its title
and valuation efforts on the more significant properties. It is generally not
feasible for the Company to review in-depth every property it purchases and all
records with respect to such properties. However, even an in-depth review of
properties and records may not necessarily reveal existing or potential
problems, nor will it permit the Company to become familiar enough with the
properties to assess fully their deficiencies and capabilities. Evaluation of
future recoverable reserves of oil and gas, which is an integral part of the
property selection process, is a process that depends upon evaluation of
existing geological, engineering and production data, some or all of which may
prove to be unreliable or not indicative of future performance. To the extent
the seller does not operate the properties, obtaining access to properties and
records may be more difficult. Even when problems are identified, the seller may
not be willing or financially able to give contractual protection against such
problems, and the Company may decide to assume environmental and other
liabilities in connection with acquired properties.

Governmental Regulation

The Company's operations are affected from time to time in varying degrees by
political developments and federal, state, provincial and local laws and
regulations. In particular, oil and gas production and related operations are or
have been subject to price controls, taxes and other laws and regulations
relating to the oil and gas industry. Failure to comply with such laws and
regulations can result in substantial penalties. The regulatory burden on the
oil and gas industry increases the Company's cost of doing business and affects
its profitability. Although the Company believes it is in substantial compliance
with all applicable laws and regulations, because such laws and regulations are
frequently amended or reinterpreted, the Company is unable to predict the future
cost or impact of complying with such laws and regulations.

United States. Sales of natural gas by the Company are not regulated and are
generally made at market prices. However, the Federal Energy Regulatory
Commission ("FERC") regulates interstate natural gas transportation rates and
service conditions, which affect the marketing of natural gas produced by the
Company, as well as the revenues received by the Company for sales of such
production. Sales of the Company's natural gas currently are made at
uncontrolled market prices, subject to applicable contract provisions and price
fluctuations which normally attend sales of commodity products. The FERC's
jurisdiction over natural gas transportation was unaffected by the Decontrol
Act. While sales by producers of natural gas, and all sales of crude oil,
condensate and NGLs, can currently be made at uncontrolled market prices,
Congress could re-enact prices controls in the future.

                                       17



                                                           The Wiser Oil Company

Since the mid-1980's, the FERC has issued a series of orders that have
significantly altered the marketing and transportation of natural gas. Such
orders mandated a fundamental restructuring of interstate pipeline sales and
transportation service, including the unbundling by interstate pipelines of the
sale, transportation, storage and other components of the city-gate sales
services such pipelines previously performed. Further, they have eliminated or
substantially reduced the interstate pipelines' traditional role as wholesalers
of natural gas, and have substantially increased competition and volatility in
natural gas markets.

While the Company cannot predict what action the FERC will take on these or
related matters in the future, the Company does not believe that it will be
treated materially differently than other natural gas producers and marketers
with which it competes.

The Company's gathering operations are subject to safety and operational
regulations relating to the design, installation, testing, construction,
operation, replacement and management of facilities. Pipeline safety issues have
recently been the subject of increasing focus in various political and
administrative arenas at both the state and federal levels. The Company believes
its operations, to the extent they may be subject to current gas pipeline safety
requirements, comply in all material respects with such requirements. The
Company cannot predict what effect, if any, the adoption of this or other
additional pipeline safety legislation might have on its operations, but the
industry could be required to incur additional capital expenditures and
increased costs depending upon future legislative and regulatory changes.

The State of Texas and many other states require permits for drilling
operations, drilling bonds and reports concerning operations and impose other
requirements relating to the exploration for and production of oil and gas. Such
states also have statutes or regulations addressing conservation matters,
including provisions for the unitization or pooling of oil and gas properties,
the establishment of maximum rates of production from wells and the regulation
of spacing, plugging and abandonment of such wells. The statutes and regulations
of certain states limit the rate at which oil and gas can be produced from the
Company's properties. However, the Company does not believe it will be affected
materially differently by these statutes and regulations than any other
similarly situated oil and gas company.

Canada. In Canada producers of oil negotiate sales contracts directly with oil
purchasers, with the result that sales of oil are generally made at market
prices. The price of oil received by the Company depends in part on oil quality,
prices of competing fuels, distance to market, the value of refined products and
the supply/demand balance. Oil exports may be made pursuant to export contracts
with terms not exceeding one year in the case of light crude, and not exceeding
two years in the case of heavy crude, provided that an order approving any such
export has been obtained from the National Energy Board ("NEB"). Any oil export
to be made pursuant to a contract of a longer duration requires an exporter to
obtain an export license from the NEB and the issue of such license requires the
approval of the Governor General in Council.

In Canada the price of natural gas sold is determined by negotiation between
buyers and sellers. Natural gas exported from Canada is subject to regulation by
the NEB and the government of Canada. Exporters are free to negotiate prices and
other terms with purchasers, provided that export contracts in excess of two
years must continue to meet certain criteria prescribed by the NEB and the
government of Canada. As is the case with oil, natural gas exports for a term of
less than two years must be made pursuant to an NEB order, or, in the case of
exports for a longer duration, pursuant to an NEB license and Governor General
in Council approval. The government of Alberta also regulates the volume of
natural gas that may be removed from Alberta for consumption elsewhere based on
such factors as reserve availability, transportation arrangements and marketing
considerations.

In addition to Canadian federal regulation, Alberta and certain other provinces
have legislation and regulations that govern royalties payable on production
from Crown lands. The royalty regime that is in place at a particular time or
location is a significant factor in the profitability of oil and gas production.
Royalties payable on production from lands other than Crown lands are determined
by negotiations between the mineral owner and the lessee. Crown royalties are
determined by governmental regulation and are generally calculated as a
percentage of the value of the gross production. The rate of royalties payable
generally depends in part on prescribed reference prices, well productivity,
geographical location, field discovery date and the type and quality of the
petroleum product produced.

                                       18



                                                           The Wiser Oil Company

From time to time the government of Alberta has established incentive programs
that have included royalty rate reductions, royalty holidays and tax credits for
the purpose of encouraging oil and gas exploration or enhanced production
projects. For example, a producer of oil or gas is entitled to a credit against
the royalties payable to the Crown by virtue of the Alberta Royalty Tax Credit
("ARTC") program. The ARTC program provides a rebate on Crown royalties paid in
respect of eligible producing properties. The ARTC program is based on a price-
sensitive formula, and the ARTC rate currently varies between 25% and 75% of the
royalty otherwise payable on production. The ARTC rate is currently applied to a
maximum of $2.0 million of Alberta Crown royalties otherwise payable by each
producer or associated group of producers in each tax year. The rate is
established quarterly based on average "par price," as determined by the Alberta
Department of Energy for the previous quarterly period. Producing properties
acquired from corporations claiming maximum entitlement to ARTC will generally
not be eligible for ARTC.

Environmental Matters

The Company's operations and properties are subject to extensive and changing
federal, state, provincial and local laws and regulations relating to
environmental protection, including the generation, storage, handling and
transportation of oil and gas and the discharge of materials into the
environment, and relating to safety and health. The recent trend in
environmental legislation and regulation generally is toward stricter standards,
and this trend will likely continue. These laws and regulations may require the
acquisition of a permit or other authorization before construction or drilling
commences and for certain other activities; limit or prohibit construction,
drilling and other activities on certain lands lying within wilderness and other
protected areas; and impose substantial liabilities for pollution resulting from
the Company's operations. The permits required for various of the Company's
operations are subject to revocation, modification and renewal by issuing
authorities. Governmental authorities have the power to enforce compliance with
their regulations, and violations are subject to fines, penalties or
injunctions. In the opinion of management, the Company is in substantial
compliance with current applicable environmental laws and regulations, and the
Company has no material commitments for capital expenditures to comply with
existing environmental requirements. Nevertheless, changes in existing
environmental laws and regulations or in interpretations thereof could have a
significant impact on the Company. The impact of such changes, however, would
not likely be any more burdensome to the Company than to any other similarly
situated oil and gas company.

The Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), also known as the "Superfund" law, and similar state laws impose
liability, without regard to fault or the legality of the original conduct, on
certain classes of persons that are considered to have contributed to the
release of a "hazardous substance" into the environment. These persons include
the owner or operator of the disposal site or sites where the release occurred
and companies that disposed or arranged for the disposal of the hazardous
substances found at the site. Persons who are or were responsible for releases
of hazardous substances under CERCLA may be subject to joint and several
liability for the costs of cleaning up the hazardous substances that have been
released into the environment and for damages to natural resources. Furthermore,
neighboring landowners and other third parties may file claims for personal
injury and property damage allegedly caused by the hazardous substances released
into the environment.

The Company generates typical oil and gas field wastes, including hazardous
wastes, that are subject to the federal Resources Conservation and Recovery Act
and comparable state statutes. The United States Environmental Protection Agency
and various state agencies have limited the approved methods of disposal for
certain hazardous and nonhazardous wastes. Furthermore, certain wastes generated
by the Company's oil and gas operations that are currently exempt from
regulation as "hazardous wastes" may in the future be designated as "hazardous
wastes," and therefore be subject to more rigorous and costly operating and
disposal requirements.

                                       19



                                                           The Wiser Oil Company

The Oil Pollution Act ("OPA") imposes a variety of requirements on responsible
parties for onshore and offshore oil and gas facilities and vessels related to
the prevention of oil spills and liability for damages resulting from such
spills in waters of the United States. The "responsible party" includes the
owner or operator of an onshore facility or vessel or the lessee or permittee
of, or the holder of a right of use and easement for, the area where an onshore
facility is located. OPA assigns liability to each responsible party for oil
spill removal costs and a variety of public and private damages from oil spills.
Few defenses exist to the liability for oil spills imposed by OPA. OPA also
imposes financial responsibility requirements. Failure to comply with ongoing
requirements or inadequate cooperation in a spill event may subject a
responsible party to civil or criminal enforcement actions.

The Company's Canadian operations are also subject to environmental regulation
pursuant to local, provincial and federal legislation. Canadian environmental
legislation provides for restrictions and prohibitions on releases or emissions
of various substances produced in association with certain oil and gas industry
operations and can affect the location of wells and facilities and the extent to
which exploration and development is permitted. In addition, legislation
requires that well and facilities sites be abandoned and reclaimed to the
satisfaction of provincial authorities. In most cases, an environmental
assessment and review is required prior to initiating exploration or development
projects or undertaking significant changes to existing projects. A breach of
such legislation may result in the imposition of fines and issuance of clean-up
orders. Environmental legislation in Alberta has recently undergone a major
revision and has been consolidated in the Environmental Protection and
Enhancement Act. Under the new Act, environmental standards and compliance for
releases, clean-up and reporting are stricter. Also, the range of enforcement
actions available and the severity of penalties have been significantly
increased. These changes will have an incremental effect on the cost of
conducting operations in Alberta.

The Company owns, leases or operates numerous properties that for many years
have produced or processed oil and gas. The Company also owns and operates
natural gas gathering, transportation and processing systems. It is not uncommon
for such properties to be contaminated with hydrocarbons or polychlorinated
biphenyls. Although the Company or previous owners of these interests may have
used operating and disposal practices that were standard in the industry at the
time, hydrocarbons, polychlorinated biphenyls or other wastes may have been
disposed of or released on or under the properties or on or under other
locations where such wastes have been taken for disposal. These properties may
be subject to federal or state requirements that could require the Company to
remove any such wastes or to remediate the resulting contamination. In addition,
some of the Company's properties are operated by third parties over whom the
Company has no control. Notwithstanding the Company's lack of control over
properties operated by others, the failure of the previous owners or operators
to comply with applicable environmental regulations may, in certain
circumstances, adversely impact the Company.

Abandonment Costs

The Company is responsible for payment of plugging and abandonment costs on its
oil and gas properties pro rata to its working interest. Based on its
experience, the Company anticipates that the ultimate aggregate salvage value of
lease and well equipment located on its properties will exceed the costs of
abandoning such properties. There can be no assurance, however, that the Company
will be successful in avoiding additional expenses in connection with the
abandonment of any of its properties. In addition, abandonment costs and their
timing may change due to many factors, including actual production results,
inflation rates and changes in environmental laws and regulations.

Employees

At March 9, 2001, the Company employed 62 full-time employees; 3 were executive
officers, 31 were professional and administrative personnel and 28 were field
personnel. Of the total employees, 48 were located in the United States and 14
were located in Canada. At March 9, 2001, none of the Company's employees were
represented by a labor union. The Company considers its relations with its
employees to be good.

Glossary of Oil and Gas Terms

The following are abbreviations and definitions of terms commonly used in the
oil and gas industry that are used in this Report.

"Bbl" means a barrel of 42 U.S. gallons.

"Bcf" means billion cubic feet.

"BOE" means barrels of oil equivalent, converting volumes of natural gas to oil
equivalent volumes using a ratio of six Mcf of natural gas to one Bbl of oil.

"completion" means the installation of permanent equipment for the production of
oil or gas.

"development well" means a well drilled within the proved area of an oil or gas
reservoir to the depth of a stratigraphic horizon known to be productive.

"dry hole" or "dry well" means a well found to be incapable of producing
hydrocarbons in sufficient quantities such that proceeds from the sale of such
production exceed production expenses and taxes.

"exploratory well" means a well drilled to find and produce oil or gas reserves
not classified as proved, to find a new production reservoir in a field
previously found to be productive of oil or gas in another reservoir or to
extend a known reservoir.

"farm-in" means an agreement pursuant to which the owner of a working interest
in an oil and gas lease assigns the working interest or a portion thereof to
another party who desires to drill on the leased acreage. Generally, the
assignee is required to drill one or more wells in order to earn its interest in
the acreage. The assignor usually retains a royalty or reversionary interest in
the lease. The interest received by an assignee is a "farm-in."

"gas" means natural gas.

"gross" when used with respect to acres or wells, refers to the total acres or
wells in which the Company has a working interest.

"infill drilling" means drilling of an additional well or wells provided for by
an existing spacing order to more adequately drain a reservoir.

"MBbl" means thousand Bbls.

"MBOE" means thousand BOE.

"Mcf" means thousand cubic feet.

"MMBOE" means million BOE.

"MMBtu" means one million British Thermal Units. British Thermal Unit means the
quantity of heat required to raise the temperature of one pound of water by one
degree Fahrenheit.

"MMcf" means million cubic feet.

"net" when used with respect to acres or wells, refers to gross acres or wells
multiplied, in each case, by the percentage working interest owned by the
Company.

"net production" means production that is owned by the Company less royalties
and production due others.

"NGL" means natural gas liquid.

"operator" means the individual or company responsible for the exploration,
development and production of an oil or gas well or lease.

"Present Value" when used with respect to oil and gas reserves, means the
estimated future gross revenues to be generated from the production of proved
reserves calculated in accordance with the guidelines of the SEC, net of
estimated production and future development costs, using prices and costs as of
the date of estimation without future escalation (except to the extent a
contract specifically provides otherwise), without giving effect to non-property
related expenses such as general and administrative expenses, debt service,
future income tax expense and depreciation, depletion and amortization, and
discounted using an annual discount rate of 10%.

"productive wells" or "producing wells" consist of producing wells and wells
capable of production, including wells waiting on pipeline connections.

"proved developed reserves" means reserves that can be expected to be recovered
through existing wells with existing equipment and operating methods.
Additional oil and gas expected to be obtained through the application of fluid
injection or other improved recovery techniques for supplementing the natural
forces and mechanisms of primary recovery will be included as "proved developed
reserves" only after testing by a pilot project or after the operation of an
installed program has confirmed through production response that increased
recovery will be achieved.

"proved reserves" means the estimated quantities of crude oil, natural gas and
NGLs which upon analysis of geological and engineering data appear with
reasonable certainty to be recoverable in future years from known reservoirs
under existing economic and operating conditions, i.e., prices and costs as of
the date the estimate is made. Prices include consideration of changes in
existing prices provided only by contractual arrangements, but not on
escalations based upon future conditions.

  (i)  Reservoirs are considered proved if economic producibility is supported
       by either actual production or conclusive formation tests. The area of a
       reservoir considered proved includes (A) that portion delineated by
       drilling and defined by gas-oil and/or oil-water contacts, if any; and
       (B) the immediately adjoining portions not yet drilled, but which can be
       reasonably judged as economically productive on the basis of available
       geological and engineering data. In the absence of information on fluid
       contacts, the lowest known structural occurrence of hydrocarbons controls
       the lower proved limit of the reservoir.

  (ii) Reserves which can be produced economically through application of
       improved recovery techniques (such as fluid injection) are included in
       the "proved" classification when successful testing by a pilot project,
       or the operation of an installed program in the reservoir, provides
       support for the engineering analysis on which the project or program was
       based.

  (iii) Estimates of proved reserves do not include the following: (A) oil that
        may become available from known reservoirs but is classified separately
        as "indicated additional reserves"; (B) crude oil, natural gas and NGLs,
        the recovery of which is subject to reasonable doubt because of
        uncertainty as to geology, reservoir characteristics or economic
        factors; (C) crude oil, natural gas, and NGLs, that may occur in
        undrilled prospects; and (D) crude oil, natural gas and NGLs that may be
        recovered from oil shales, coal, gilsonite and other such resources.

"proved undeveloped reserves" means reserves that are expected to be recovered
from new wells on undrilled acreage, or from existing wells where a relatively
major expenditure is required for completion. Reserves on undrilled acreage
shall be limited to those drilling units offsetting productive units that are
reasonably certain of production when drilled. Proved reserves for other
undrilled units can be claimed only where it can be demonstrated with certainty
that there is continuity of production from the existing productive formation.
Under no circumstances should estimates for proved undeveloped reserves be
attributable to any acreage for which an application of fluid injection or other
improved recovery technique is contemplated, unless such techniques have been
proved effective by actual tests in the area and in the same reservoir.

"recompletion" means the completion for production of an existing well bore in
another formation from that in which the well has been previously completed.

"reserves" means proved reserves.

"reservoir" means a porous and permeable underground formation containing a
natural accumulation of producible oil and/or gas that is confined by
impermeable rock or water barriers and is individual and separate from other
reservoirs.

"royalty" means an interest in an oil and gas lease that gives the owner of the
interest the right to receive a portion of the production from the leased
acreage (or of the proceeds of the sale thereof), but generally does not require
the owner to pay any portion of the costs of drilling or operating the wells on
the leased acreage. Royalties may be either landowner's royalties, which are
reserved by the owner of the leased acreage at the time the lease is granted, or
overriding royalties, which are usually reserved by an owner of the leasehold in
connection with a transfer to a subsequent owner.

"2-D seismic" means an advanced technology method by which a cross-section of
the earth's subsurface is created through the interpretation of reflecting
seismic data collected along a single source profile.

"3-D seismic" means an advanced technology method by which a three dimensional
image of the earth's subsurface is created through the interpretation of
reflection seismic data collected over surface grid. 3-D seismic surveys allow
for a more detailed understanding of the subsurface than do conventional surveys
and contribute significantly to field appraisal, development and production.

"working interest" means an interest in an oil and gas lease that gives the
owner of the interest the right to drill for and produce oil and gas on the
leased acreage and requires the owner to pay a share of the costs of drilling
and production operations. The share of production to which a working interest
owner is entitled will always be smaller than the share of costs that the
working interest owner is required to bear, with the balance of the production
accruing to the owners of royalties.

"workover" means operations on a producing well to restore or increase
production.

    costs and exploration costs to net income (excluding marketable security
    sales gains and divid ends and interest). EBITDA should not be considered in
    isolation or as a substitute for net income, operating cash flows or any

Item 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

The following discussion is intended to assist in an understanding of the
Company's historical financial position and results of operations for each year
in the three-year period ended December 31, 2000. The Company's Consolidated
Financial Statements and notes thereto included elsewhere in this Report contain
detailed information that should be referred to in conjunction with the
following discussion.

General

The Company's future results of operations and growth are substantially
dependent upon (i) its ability to acquire or find and successfully develop
additional oil and gas reserves and (ii) the prevailing prices for oil and gas.
At December 31, 2000, the Company's proved reserves were comprised of
approximately 96% proved developed reserves, and the Company does not have a
large inventory of development drilling locations or enhanced recovery projects
to pursue after 2000. If the Company is unable to economically acquire or find
significant new reserves for development and exploitation, the Company's oil and
gas production, and thus its revenues, would likely decline gradually as its
reserves are produced. In addition, oil and gas prices are dependent upon
numerous factors beyond the Company's control, such as economic, political and
regulatory developments and competition from other sources of energy. The oil
and gas markets have historically been very volatile. In particular, oil prices
during 1998 were at their lowest levels since 1986. As a result, the Company's
results of operations were adversely affected. During the last half of 1999 and
during 2000, oil and gas prices increased significantly from 1998. Any
significant and extended decline in the price of oil or gas would have a
material adverse effect on the Company's financial condition and results of
operations, and could result in a reduction in the carrying value of the
Company's proved reserves and adversely affect its access to capital.

SFAS No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-
Lived Assets to Be Disposed Of," requires the Company to assess the need for an
impairment of capitalized costs of proved oil and gas properties and the costs
of wells and related equipment and facilities on a property-by-property basis.
Applying SFAS No. 121, the Company recognized non-cash property impairment
charges of $0.7 million in 2000, $2.2 million in 1999 and $3.8 million in 1998.

Results of Operations

Production information presented below includes volumes of natural gas purchased
for resale; however, per unit of production information with respect to
production and operating expenses, depreciation, depletion and amortization and
general and administrative costs is calculated without including such volumes.
Such volumes were 0 MMcf in 2000, 148 MMcf in 1999 and 608 MMcf in 1998.

In April and May 1999, the Company entered into three separate agreements to
sell its oil and gas properties in the Appalachia area, certain oil and gas
properties in Texas and New Mexico and virtually all of its oil and gas royalty
interests in the United States ("Second Quarter Property Sales"). The Second
Quarter Property Sales were closed in April and May 1999 for an aggregate sales
price of $42.3 million before fees and adjustments, and represented
approximately 19% of the Company's proved reserves as of December 31, 1998. The
Company recognized a net gain of $3.4 million in 1999 from the Second Quarter
Property Sales and the revenues and expenses associated with the sold properties
are included in the Company's consolidated statements of income through the
various closing dates.

In May 2000, the Company received $13.7 million in net proceeds from the sale of
600,000 shares of convertible preferred stock to Wiser Investment Company, LLC
and its affiliates ("WIC"). See Note 11 to the Company's Consolidated Financial
Statements for additional information about the convertible preferred stock. WIC
has the option, until May 25, 2001, to purchase up to an additional 400,000
shares of convertible preferred stock for $10.0 million, or $25 per share. The
convertible preferred stock is convertible at the option of the holder into
shares of the Company's common stock at a conversion price of $4.25 per common
share.

In connection with the sale of the preferred stock, three of the Company's four
officers were terminated in 2000 and the Company recognized $2.2 million of
expense related to such terminations which is included in general and
administrative expense in the Consolidated Statements of Income.

Comparison of 2000 to 1999

Revenues

Oil and gas sales increased $19.4 million or 41% to $67.0 million in 2000 from
$47.6 million in 1999, due to significantly higher oil and gas prices received
in 2000, which were partially offset by lower oil and gas production. Oil sales
for 2000 were $7.1 million higher than 1999 as the average price received for
oil sales in 2000 was $21.69 per barrel, up $6.51 per barrel or 43% from 1999.
Net oil production for 2000 was 1,505,000 barrels, down 179,000 barrels or 11%
from 1,684,000 barrels in 1999. The property sales in the second quarter of 1999
accounted for approximately 56,000 barrels of the decrease and oil production
from the Maljamar and Wellman fields in 2000 was approximately 103,000 barrels
lower than 1999. Canadian oil production in 2000 was approximately 42,000
barrels lower than 1999 due primarily to declining oil production from the
Provost and Evi fields. Gas sales for 2000 were $10.8 million higher than 1999
as the average price received for gas sales in 2000 was $3.31 per Mcf, an
increase of $1.48 per Mcf or 81% from 1999. Net gas production for 2000 was
8,938 MMCF, down 1,310 MMCF or 13% from 1999. The property sales in the second
quarter of 1999 accounted for approximately 1,215 MMCF of the decrease in gas
production. NGL sales for 2000 were $1.5 million higher than 1999 as the average
price received for NGL sales in 2000 was $22.19 per barrel, an increase of $9.18
per barrel or 71% from 1999. The Company's hedging activities reduced oil and
gas sales by $11.8 million in 2000. On an equivalent unit basis, total
production decreased 12% to 3,209 MBOE in 2000 from 3,641 MBOE in 1999.

Interest income increased 157% to $1.8 million in 2000 from $0.7 million in 1999
due to higher average cash balances in 2000.

Gain on sales of properties were $0.1 million in 2000 compared to $3.6 million
in 1999 due to the Second Quarter Property Sales in 1999.

Costs and Expenses

Production and operating expense for 2000 increased $3.0 million or 14% from
1999 and, on a BOE basis (excluding 148 MMCF of gas purchased for resale during
1999), increased to $7.52 per BOE or 29% from $5.84 per BOE in 1999. The
increase in production and operating expense was attributable primarily to the
Maljamar and Wellman fields which were $3.6 million higher in 2000 than in 1999
due to well repairs and maintenance at both fields and higher CO2 injection at
Wellman. In addition, production taxes in 2000 were $0.9 million higher than
1999 due to higher realized oil and gas prices. Production and operating expense
in 1999 included approximately $1.1 million associated with the properties sold
in the second quarter of 1999.

Depreciation, depletion and amortization, ("DD&A") for 2000, decreased $2.0
million or 11% from 1999 due primarily to lower oil and gas production and the
property sales in the second quarter of 1999.

Impairment expense decreased 68% to $0.7 million in 2000 from $2.2 million in
1999. The Company recognized impairment expense of $0.7 million in 2000 for the
Elm field in Canada which was sold in October 2000 at a sales price which was
below its carrying value. Impairment expense in 1999 resulted from lower than
expected reserve estimates for certain properties.

Exploration expense decreased 46% to $3.8 million in 2000 from $7.1 million in
1999. Abandoned lease expense decreased 78% to $1.0 million in 2000 from $4.6
million in 1999. Dry hole expense increased 69% to $2.2 million in 2000 from
$1.3 million in 1999. Geological and geophysical expenses in 2000 were $0.6
million, down 25% from $0.8 million in 1999.

General and administrative expense ("G&A") in 2000 was $8.7 million, up $1.9
million from 1999 due primarily to $2.2 million of officer termination expense
which was partially offset by reduced payroll expense in 2000. G&A per BOE
increased 45% to $2.72 per BOE in 2000 from $1.88 per BOE in 1999.

Income tax benefit for 2000 was zero compared to a tax benefit of $0.9 million
in 1999. The Company had a net operating loss carryforward for Federal income
tax purposes of $18.6 million at December 31, 2000 and $13.9 million at December
31, 1999. The tax benefits of carryforwards are recorded as an asset to the
extent that management assesses the future utilization of such carryforwards as
"more likely than not." When the future utilization of some portion of the
carryforwards is determined not to be "more likely than not," a valuation
allowance is provided to reduce the recorded tax benefits from such assets. At
December 31, 2000 and 1999, a valuation allowance was provided to reduce
deferred tax assets to an amount equal to deferred tax liabilities. Accordingly,
no income tax expense was recognized in 2000, and income tax benefits were
recognized in 1999 only to the extent of the Company's existing deferred income
tax liability.

Net income (loss) available for common stock was $3.5 million and basic net
earnings per share was $0.39 in 2000 compared to a net loss available for common
stock of $14.9 million and basic net loss per share of $1.66 in 1999.

Comparison of 1999 to 1998

Revenues

Oil and gas sales decreased $11.6 million or 20% to $47.6 million in 1999 from
$59.2 million in 1998, due to the Second Quarter Property Sales, which accounted
for $9.8 million of the decrease and also due to lower oil and gas production
which was partially offset by higher oil and NGL prices. Oil production in 1999
was 709 MBbls lower than 1998 oil production, with 89% of the decrease
attributed to lower oil production from the Maljamar field in New Mexico of 249
MBbls, lower oil production in Canada of 217 MBbls, primarily attributable to
the Evi and Provost fields, and a reduction of 168 MBbls related to the Second
Quarter Property Sales. The average oil price received in 1999 increased 22% to
$15.18 per Bbl from $12.46 per Bbl in 1998. Gas production during 1999 decreased
29% to 10.2 Bcf from 14.4 Bcf in 1998. Approximately 21% of the decrease in gas
production was attributable to the Second Quarter Property Sales and
approximately 3% of the decrease in gas production was due to lower gas
production in South Texas, which was 499 MMcf lower than 1998. The average gas
price received in

                                                           The Wiser Oil Company

1999 was $1.83 per Mcf or $0.01 less than 1998. As a result of hedging
activities, oil and gas sales were decreased by $3.6 million in 1999 and
increased by $0.2 million in 1998. On an equivalent unit basis, total production
decreased 29% to 3,641 MBOE in 1999 from 5,109 MBOE in 1998.

Dividends and interest increased 133% to $0.7 million in 1999 compared to $0.3
million in 1998 as a result of higher interest income earned on the net proceeds
from the Second Quarter Property Sales which were invested in short-term
investments.

Pension plan curtailment gain of $0.8 million in 1998 was recognized as a result
of amendments to the Company's pension plan in December 1998 which curtailed
certain pension benefits. There were no such amendments in 1999.

Gain on sales of properties were $3.6 million in 1999 compared to $0.6 million
in 1998 due to the Second Quarter Property Sales. Property sales in 1998
consisted of several non-strategic oil and gas properties.

Costs and Expenses

Production and operating expense decreased 20% to $21.1 million in 1999 from
$26.5 million in 1998 primarily due to the Second Quarter Property Sales, which
reduced production and operating expenses by $3.5 million in 1999, and also due
to cost cutting measures implemented at the Maljamar field which reduced
production and operating expenses in 1999 by $1.5 million compared to 1998. On a
BOE basis, production and operating expense increased 10% to $5.84 per BOE in
1999 from $5.29 per BOE in 1998 primarily as a result of higher production and
operating expenses per BOE at the Maljamar and Wellman fields and the Second
Quarter Property Sales which included properties with a lower than average
production and operating expense per BOE.

Purchase natural gas decreased 79% to $0.3 million in 1999 from $1.4 million in
1998 due to the Second Quarter Property Sales.

DD&A decreased $8.1 million or 31% to $17.7 million in 1999 from $25.8 million
in 1998 and DD&A per BOE decreased 5% to $4.88 per BOE in 1999 from $5.15 per
BOE in 1998. U.S. DD&A decreased $5.9 million, due primarily to the Second
Quarter Property Sales, and Canadian DD&A decreased $2.2 million.

Impairment expense decreased 42% to $2.2 million in 1999 from $3.8 million in
1998. Impairment expense in 1999 resulted from lower than expected reserve
estimates for certain properties and impairment expense in 1998 was due
primarily to unusually low oil prices used to value reserves at year-end 1998.

Exploration expense decreased 54% to $7.1 million in 1999 from $15.3 million in
1998 as the Company significantly curtailed its exploration activities in 1999
due to low oil prices experienced in 1998 and the first quarter of 1999. Dry
hole expense decreased 79% to $1.3 million in 1999 from $6.1 million in 1998.
Geological and geophysical expenses in 1999 were $0.8 million, down 76% from
$3.4 million in 1998.

General and administrative expense ("G&A") decreased 36% to $6.8 million in 1999
from $10.6 million in 1998 and G&A per BOE decreased 4% to $1.88 per BOE in 1999
from $1.96 per BOE in 1998. The decrease in G&A was attributable in part to an
informal cost reduction program that was implemented by the Company in December
1998 that involved reducing its workforce by approximately 36% and reducing
other discretionary administrative expenses. In connection with this cost
reduction program, the Company recognized approximately $545,000 of employee
severance expense in 1998.

Income tax benefit decreased $9.8 million to a tax benefit of $0.9 million in
1999 from a tax benefit of $10.7 million in 1998. The Company had a net
operating loss carryforward of approximately $16 million at December 31, 1999
and since full realization of the future tax benefits of the net operating loss
carryforward was determined by the Company to not be "more likely than not" at
December 31, 1999, only $0.9 million of income tax benefit was recognized in
1999.

                                                           The Wiser Oil Company

Net loss decreased $9.6 million to a net loss of $14.9 million in 1999 from a
net loss of $24.5 million in 1998 as total costs and expenses and income taxes
for 1999 were $18.2 million lower than 1998 and total revenues for 1999 were
only $8.6 million lower than 1998.

Liquidity and Capital Resources

Cash flows

Operating cash flows in 2000 were $17.1 million, up $10.6 million from $6.5
million in 1999 primarily as a result of increased oil and gas sales which were
offset in part by higher production and operating expense and higher general and
administrative expense. Capital expenditures during 2000 were $20.1 million, up
$11.8 million from $8.3 million in 1999. The major components of capital
expenditures for 2000 were $10.2 million for development activities, $5.9
million for exploration activities and $3.7 million for property acquisitions.
The Company's capital and exploration budget for 2001 is approximately $36
million. The Company received $41.0 million in net sales proceeds from the sale
of oil and gas properties during 1999 compared to $2.0 million in proceeds
received during 2000. On a cash basis, the Company paid $12.0 million in
interest expense in 2000 and no income taxes were paid in 2000. Cash flows from
financing activities in 2000 included $13.7 million of net proceeds from the
issuance of preferred stock in May 2000. Cash flows from financing activities in
1999 consisted of repaying $21 million of borrowings under the Credit Agreement,
formerly with NationsBank of Texas, N.A., and borrowing $0.5 million under the
Restated Credit Agreement with Bank One Texas, NA.

Financial Position

Cash and cash equivalents increased $12.7 million from $21.4 million at December
31, 1999 to $34.1 million at December 31, 2000. The increase was attributable
primarily to $13.7 million of net proceeds from the issuance of preferred stock
in May 2000. Working capital of $35.2 million at December 31, 2000 was $17.3
million higher than working capital of $17.9 million at December 31, 1999 due
primarily to increased cash and cash equivalents of $12.7 million and increased
accounts receivable of $7.1 million. Net property and equipment increased $0.4
million and total assets increased $19.6 million during 2000 to $216.3 million
at December 31, 2000. Stockholders' equity increased $17.2 million during 2000
to $74.3 million at December 31, 2000.

At December 31, 2000, capitalization totaled $199.4 million and consisted of
$125.1 million of total debt (63%) and $74.3 million of stockholders' equity
(37%).

Capital Sources

Funding for the Company's business activities has been provided by cash flow
from operations, borrowings and the issuance of preferred stock in May 2000.
While the Company regularly engages in discussions relating to potential
acquisitions of oil and gas properties, the Company has no current agreement or
commitment with respect to any such acquisitions which would be material to the
Company. Any future acquisitions may require additional financing and will be
dependent upon financing arrangements available at the time.

The Company entered into a Credit Agreement with a group of banks which provides
for the issuance of letters of credit and for revolving credit loans to the
Company (the "Credit Agreement"). On March 23, 1999, a financial institution
("New Lender") purchased all of the rights and obligations of the Credit
Agreement from Nations Bank of Texas, N.A. and the Bank of Montreal and became
the new Agent under the Credit Agreement.

In April 1999, the Company used $10 million of proceeds from the sale of oil and
gas properties to reduce the outstanding balance under the Credit Agreement to
$11 million. On May 10, 1999, the Company entered into a Restated Credit
Agreement with Bank One, Texas, N.A. (the "BankOne Revolver"). The Company
borrowed $11 million under the BankOne Revolver and repaid in full the
outstanding principal balance of $11 million under the Credit Agreement and the
Credit Agreement was terminated. Also in May 1999, the Company used $10.5
million of proceeds from the sale of oil and gas properties to reduce the
BankOne Revolver balance to $0.5 million.

                                                           The Wiser Oil Company

The BankOne Revolver provides the Company with up to a $25 million line of
credit through April 30, 2001. The amounts available for borrowing are based on
the Company's oil and gas reserves and the Company's Borrowing Base at December
31, 2000 was $8 million. Available loan and interest options are (i) Prime Rate
Loans, at the bank's prime interest rate and (ii) Eurodollar Loans, at LIBOR
plus 2.5%, 2.75% or 3% depending on the percentage of the Borrowing Base
actually borrowed by the Company. The commitment fee on the unused Borrowing
Base is 0.5%. The BankOne Revolver imposes certain restrictions on sales of
assets, payment of dividends and incurrence of indebtedness and requires the
Company to, among other things, maintain certain financial ratios and make
monthly escrow deposits of $1.0 million to fund the semi-annual interest
payments on the 9 1/2% Senior Subordinated Notes. The Company is currently
negotiating a new credit facility and, subject to the completion of the
negotiations, the Company has classified the entire $0.5 million balance
outstanding at December 31, 2000 as a current liability in the Consolidated
Balance Sheets.

On April 13, 1999, the Company entered into a Purchase and Sale Agreement with
Prince Minerals, Ltd. to sell certain producing and non-producing mineral
interests ("Mineral Properties") for $10 million effective April 1, 1999. The
sale closed on April 21, 1999. The producing portion of the oil and gas
properties comprising the Mineral Properties represented approximately 2% of the
Company's total proved oil and gas reserves at December 31, 1998. The sales
proceeds were used to reduce the outstanding balance under the Credit Agreement
to approximately $11 million.

On April 12, 1999, the Company entered into a Purchase and Sale Agreement with
Columbia Natural Resources to sell all of the Company's oil and gas properties
in Kentucky, Tennessee and West Virginia ("Appalachia Properties") for $28
million effective April 1, 1999. The sale closed on May 12, 1999. The oil and
gas properties comprising the Appalachia Properties represented approximately
15% of the Company's total proved oil and gas reserves at December 31, 1998. The
sales proceeds were used to reduce the outstanding balance under the Credit
Agreement to approximately $11 million, and for general corporate purposes.

In addition, the Company sold a number of smaller, non-strategic oil and gas
properties in Texas and New Mexico for an aggregate sales price of $4.3 million.
This sale closed on May 25, 1999. The sales proceeds from these properties were
used for general corporate purposes.

The Company believes that cash flows from operations and borrowings under a new
credit facility will be sufficient to meet anticipated capital and exploration
expenditure requirements (excluding any material property acquisitions) in 2001.
If the Company's cash flows from operations and borrowings are not sufficient to
satisfy its capital and exploration expenditure requirements, there is no
assurance that additional equity or debt financing will be available to meet
such requirements.

Capital and Exploration Expenditures

The Company requires capital primarily for the acquisition, development and
exploitation of, and the exploration for, oil and gas properties, the repayment
of indebtedness and general working capital needs. During 2001, subject to
market conditions and drilling and operating results, the Company expects to
spend approximately $36 million on acquisition, development, exploitation and
exploration activities.

Other Matters

Environmental and Other Regulatory Matters

The Company's business is subject to certain federal, state, provincial and
local laws and regulations relating to the development, exploitation, production
and gathering of, and the exploration for, oil and gas, including those relating
to the protection of the environment. Many of these laws and regulations have
become more stringent in recent years, often imposing greater liability on a
larger number of potentially responsible parties. Although the Company believes
it is in substantial compliance with all applicable laws and regulations, the
requirements imposed by laws and regulations are frequently changed and subject
to interpretation, and the Company is unable to predict the ultimate cost of
compliance with these requirements or their effect on its operations. Although
significant expenditures may be required to comply with governmental laws and
regulations applicable to the Company, compliance has not had a material adverse
effect on the earnings or competitive position of the Company.

New Accounting Standards

The Company adopted the following pronouncements in 1998:

     SFAS No. 130, "Reporting Comprehensive Income" requires that all items that
     are to be recognized under accounting standards as components of
     comprehensive income be reported in a financial statement that is displayed
     with the same prominence as other financial statements, and

     SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
     Information" requires reporting of financial and descriptive information
     about a company's reportable operating segments. The Company has identified
     only one operating segment, which is the exploration for and production of
     oil and gas.

In June 1998, the Financial Accounting Standards Board issued SFAS 133
"Accounting for Derivative Instruments and Hedging Activities" which is
effective for all fiscal years beginning after June 15, 2000 (January 1, 2001
for the Company). SFAS No. 133 requires that derivatives be reported on the
balance sheet at fair value and, if the derivative is not designated as a
hedging instrument, changes in fair value must be recognized in earnings in the
period of change. If the derivative is designated and qualifies as a hedge and
to the extent such hedge is determined to be effective, changes in fair value
are either offset by the change in fair value of the hedged asset or liability
(if applicable) or reported as a component of other comprehensive income in the
period of change, and subsequently recognized in earnings when the offsetting
hedged transaction occurs. The definition of derivatives has also been expanded
to include contracts that require physical delivery of oil and gas if the
contract allows for net cash settlement. The Company uses derivatives to hedge
oil and gas price risk and gains or losses on such derivatives prior to the
adoption of SFAS No. 133 were recorded as adjustments to oil and gas sales. The
Company adopted SFAS No. 133 on January 1, 2001 and its existing oil and gas
hedging contracts were designated as cash flow hedges. The effective portion of
the gain or loss on a cash flow hedge must be reported as a component of other
comprehensive income and be reclassified into earnings in the same period or
periods during which the hedged forecasted transaction affects earnings. The
ineffective portion, if any, of the gain or loss on a cash flow hedge must be
recognized currently in earnings. Based on the cash flow hedges in effect on
December 31, 2000, derivative liabilities of approximately $3.1 million would be
recognized in the Company's consolidated balance sheet with an offsetting amount
recognized in accumulated other comprehensive loss.

Disclosure Regarding Forward-Looking Statements

This Report includes "forward-looking statements" within the meaning of Section
27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act
of 1934. All statements other than statements of historical facts included in
this Report, including without limitation statements in this "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
under "Business" and "Properties" regarding proved reserves, estimated future
net revenues, Present Values, planned capital expenditures (including the amount
and nature thereof), increases in oil and gas production, the number of wells
anticipated to be drilled and the Company's financial position, business
strategy and other plans and objectives for future operations, are forward-
looking statements. Although the Company believes that the expectations
reflected in such forward-looking statements are reasonable, there can be no
assurance that the actual results or developments anticipated by the Company
will be realized or, even if substantially realized, that they will have the
expected consequences to or effects on its business or operations. Among the
factors that could cause actual results to differ materially from the Company's
expectations are the volatility of oil and gas prices, the ability to acquire or
find and successfully develop additional oil and gas reserves, the uncertainty
of estimates of reserves and future net revenues, risks relating to acquisitions
of producing properties, drilling and operating risks, general economic
conditions, competition, domestic and foreign government regulations and other
factors which are beyond the Company's control. All subsequent written and oral
forward-looking statements attributable to the Company or persons acting on its
behalf are expressly qualified in their entirety by such factors. The Company
assumes no obligation to update any such forward-looking statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The Company only uses derivative financial instruments such as commodity futures
agreements to hedge against fluctuations in oil and gas prices. Gains and losses
on these derivative instruments are recorded as adjustments to oil and gas
sales. The Board of Directors of the Company have adopted a policy governing the
use of derivative instruments which requires that all derivatives used by the
Company relate to an anticipated transaction and prohibits the use of
speculative or leveraged derivatives.

Interest Rate Risk

Total debt at December 31, 2000 included $124.6 million of fixed-rate debt and
$0.5 million of floating-rate debt attributed to borrowings under the BankOne
Revolver. As a result, the Company's annual interest cost will fluctuate based
on changes in short-term interest rates. The impact on annual cash flow of a 10%
change in the short-term interest rate (approximately 95 basis points) would be
less than $0.01 million.

At December 31, 2000, the estimated fair value of the Company's fixed-rate debt
of $124.6 million was $100.0 million. The fixed-rate debt will mature in May
2007 and the floating-rate debt will mature in May 2001.

Commodity Price Risk

The Company has in the past entered into and may in the future enter into
hedging arrangements with respect to portions of its oil, natural gas and NGL
production to reduce its sensitivity to volatile commodity prices. The Company
believes that hedging, although not free of risk, allows the Company to achieve
a more predictable cash flow and to reduce exposure to price fluctuations.
However, hedging arrangements limit the benefit to the Company of increases in
the prices of the hedged commodity.  Moreover, the Company's hedging
arrangements apply only to a portion of its production and provide only partial
price protection against declines in prices.  Such arrangements may expose the
Company to risk of financial loss in certain circumstances.  The Company expects
that the amount of production it hedges will vary from time to time.  During
2000, 1999 and 1998, the Company entered into various natural gas and crude oil
forward sale agreements, natural gas price swaps and oil price collar agreements
to hedge against price fluctuations.  Oil and gas sales are adjusted for the
effects of hedging transactions as the underlying hedged production is sold.
Adjustments to oil and gas sales from the Company's hedging activities resulted
in a decrease in revenues of $11.8 million in 2000, $3.6 million in 1999 and an
increase in revenues of $0.2 million in 1998.  Based on December 31, 2000 NYMEX
futures prices, the fair value of the Company's hedging arrangements at December
31, 2000 was a loss of $3.1 million.  A 10% increase in both the oil price and
the gas price would

increase this loss by $3.1 million and a 10% decrease in both the oil price and
the gas price would decrease this loss by $3.1 million.

As of March 9, 2001 the Company's hedging arrangements were as follows:



Crude Oil:                                 Daily Volume      Price per Bbl
- ---------                                  ------------      -------------
                                                       
   January 1, 2001 to June 30, 2001        1,750 Bbls        $28.10
   January 1, 2001 to June 30, 2001        1,000 Bbls (1)    $25.00 floor, $32.00 ceiling
   July 1, 2001 to September 30, 2001      1,000 Bbls (1)    $25.00 floor, $30.46 ceiling

 Natural Gas:                              Daily Volume      Price per MMBTU
- ------------                               ------------      ---------------
   January 1, 2001 to December 31, 2001    10,000 MMBTU (1)  $4.00 floor, $6.10 ceiling
 

     (1) These are "collar" hedges whereby the Company will receive the actual
         market price if the actual market price is between the floor price and
         the ceiling price. If the actual market price is below or above the
         floor or ceiling prices, the price received by the Company will be
         limited to the floor price or ceiling price, respectively.

The Company continuously reevaluates its hedging program in light of market
conditions, commodity price forecasts, capital spending and debt service
requirements. Also see Note 1 to the Company's Consolidated Financial Statements
included elsewhere in this Report. For 2001, the Company has hedged
approximately 38% of its projected oil production and approximately 40% of its
projected gas production.

Foreign Currency Exchange Risk

The Company receives a substantial portion of its revenue in Canadian dollars
(36% in 2000). As a result, fluctuations in the exchange rates of the Canadian
dollar with respect to the U.S. dollar could have an adverse effect on the
Company's financial condition and results of operations. Historically however,
exchange rate fluctuations have not been material to the Company.

                   Report of Independent Public Accountants

To the Shareholders of The Wiser Oil Company:

We have audited the accompanying consolidated balance sheets of The Wiser Oil
Company (a Delaware corporation) and subsidiaries as of December 31, 2000 and
1999, and the related consolidated statements of income, changes in
stockholders' equity, and cash flows, after the restatement described in Note
16, for each of the three years in the period ended December 31, 2000. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States.  Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement.  An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements.  An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of The Wiser Oil
Company and subsidiaries as of December 31, 2000 and 1999, and the results of
their operations and their cash flows for each of the three years in the period
ended December 31, 2000, in conformity with accounting principles generally
accepted in the United States.

                             THE WISER OIL COMPANY

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                       December 31, 2000, 1999 and 1998

1.   Summary of Significant Accounting Policies

     a.   Principles of Consolidation - The consolidated financial statements
     include the accounts of The Wiser Oil Company ("Company"), a Delaware
     corporation, and its wholly owned subsidiaries: The Wiser Oil Company of
     Canada ("Wiser Canada"), The Wiser Marketing Company, and T.W.O.C., Inc.
     Wiser Canada was formed in 1994 to conduct the Company's Canadian
     activities. Prior to the formation of Wiser Canada, the Company's oil and
     gas operations were conducted primarily in the United States. The Wiser
     Marketing Company functions as a natural gas marketer and broker. T.W.O.C.,
     Inc. is a Delaware holding company responsible for the management of
     investment activities. Intercompany accounts and transactions have been
     eliminated. Certain reclassifications have been made to conform prior
     years' amounts to current presentation.

     b.   Risks and Uncertainties - The preparation of financial statements in
     conformity with accounting principles generally accepted in the U.S.
     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.

     c.   Oil and Gas Properties - The Company is engaged in the exploration and
     development of oil and gas in the United States and Canada. The Company
     follows the "successful efforts" method of accounting for its oil and gas
     properties. Under this method of accounting, all costs of property
     acquisitions and exploratory wells are initially capitalized. If a well is
     unsuccessful, the capitalized costs of drilling the well, net of any
     salvage value, are charged to expense. If a well finds oil and gas reserves
     that cannot be classified as proved within a year after discovery, the well
     is assumed to be impaired and the capitalized costs of drilling the well,
     net of any salvage value, are charged to expense. The capitalized costs of
     unproven properties are periodically assessed to determine whether their
     value has been impaired below the capitalized cost, and if such impairment
     is indicated, a loss is recognized. The Company considers such factors as
     exploratory drilling results, future drilling plans and the lease
     expiration terms when assessing unproved properties for impairment.
     Geological and geophysical costs and the costs of retaining undeveloped
     properties are expensed as incurred. Expenditures for maintenance and
     repairs are charged to expense, and renewals and betterments are
     capitalized. Upon disposal, the asset and related accumulated depreciation,
     depletion and amortization are removed from the accounts, and any resulting
     gain or loss is reflected currently in income.

     Long-lived assets are assessed for possible impairment in accordance with
     Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting
     for the Impairment of Long-Lived assets and for Long-Lived Assets to Be
     Disposed Of." SFAS No. 121 requires the Company to assess the need for an
     impairment of capitalized costs of proved oil and gas properties and the
     costs of wells and related equipment and facilities on a property-by-
     property basis. If an impairment is indicated based on undiscounted
     expected future cash flows, then an impairment is recognized to the extent
     that net capitalized costs exceed the estimated fair value of the property.
     Fair value of the property is estimated by the Company using the present
     value of future cash flows discounted at 10%.

                                      F-7



     The following expected future prices were used to estimate future cash
     flows to assess properties for impairment:

     Price starting after December 31, 2000, 1999 and 1998, respectively:


                                 2000       1999       1998
                                 ----       ----       ----
      Oil Price per barrel:
         Year 1..............   $25.00     $25.60     $12.35
         Year 2..............    24.00      25.60      13.73
         Year 3..............    23.00      25.60      14.57
         Year 4..............    23.00      25.60      15.81
         Thereafter..........    23.00      25.60   Escalated 3%
         Maximum.............    23.00      25.60      20.00

      Gas Price per MMBTU:
         Year 1..............   $ 5.00     $ 2.34     $ 1.96
         Year 2..............     4.50       2.34       2.25
         Year 3..............     4.00       2.34       2.34
         Year 4..............     4.00       2.34       2.55
         Thereafter..........     4.00       2.34   Escalated 3%
         Maximum.............     4.00       2.34       3.50

     Oil and gas expected future price estimates were based on NYMEX future
     prices at each year-end. Expected future prices were escalated if such
     prices were unusually low at year-end compared to historical averages, or
     expected future prices were reduced if such prices were unusually high at
     year-end compared to historical averages. These prices were applied to
     production profiles developed by the Company's engineers using proved
     developed and undeveloped reserves at December 31, 2000, 1999 and 1998,
     respectively. The Company's price assumptions change based on current
     industry conditions and the Company's future plans. During 2000, 1999 and
     1998, the Company recognized impairments of $680,000, $2,214,000 and
     $3,838,000, respectively. The impairments were determined based on the
     difference between the carrying value of the assets and the present value
     of future cash flows discounted at 10%. It is reasonably possible that a
     change in reserve or price estimates could occur in the near term and
     adversely impact management's estimate of future cash flows and
     consequently the carrying value of properties.

     d.   Depreciation, Depletion and Amortization ("DD&A") - DD&A of the
     capitalized costs of producing oil and gas properties are computed for
     individual properties using the units-of-production method based on total
     proved reserves. Other properties consist primarily of computer systems,
     vehicles and office equipment and depreciation is computed generally using
     the straight-line method over the estimated useful lives of these assets
     which range from 5 to 10 years.

     e.   Cash and Cash Equivalents - Cash equivalents consist of short-term
     investments maturing in three months or less from the date of acquisition.
     These investments of $37,022,000 at December 31, 2000 and $24,020,000 at
     December 31, 1999 are recorded at cost plus accrued interest, which
     approximates market.

     f.   Inventories - Oil and natural gas product inventories are recorded at
     the lower of average cost or market. Materials and supplies are recorded at
     the lower of average cost or market.

                                      F-8



     g.   Accrued Liabilities - In December 1998, the Company reduced its
     workforce by approximately 36% and the employee severance liability of
     $545,000 is included in general and administrative expense in the
     consolidated statements of income for the year ended December 31, 1998 and
     the entire liability was paid in 1999. Accrued liabilities also include
     accrued vacation and payroll of $168,000 at December 31, 2000 and $379,000
     at December 31, 1999.

     h.   Postretirement Benefits - SFAS No. 106, "Employers' Accounting for
     Postretirement Benefits Other Than Pensions," has no significant impact on
     the Company. The Company has no significant liabilities for postretirement
     benefits, other than pensions, and has historically recognized such
     liabilities as they are incurred.

     i.   Gas Imbalances - Gas imbalances are accounted for using the sales
     method. The Company's net imbalance position is not material at December
     31, 2000 and 1999.

     j.   Financial Instruments - The following table sets forth the book value
     and estimated fair values of financial instruments at December 31, 2000 and
     1999, respectively (000's):

                                          2000                 1999
                                     ---------------     ---------------
                                     Book      Fair      Book      Fair
                                     Value     Value     Value     Value
                                     -----     -----     -----     -----
        Cash and equivalents       $ 34,144  $ 34,144  $ 21,447   $ 21,447
        Restricted cash                 992       992       992        992
        Floating-rate debt              500       500       500        500
        Fixed-rate debt             124,600   100,000   124,526     98,750

     The fair value of the fixed-rate debt was based on quoted market prices of
     the Company's fixed-rate debt at December 31, 2000 and 1999, respectively.
     During 2000, 1999 and 1998, the Company entered into various natural gas
     forward sale agreements and natural gas price swap and oil price collar
     agreements to hedge against price fluctuations. Oil and gas sales in the
     accompanying Consolidated Statements of Income are adjusted for the effects
     of hedging transactions as the underlying hedged production is sold.
     Adjustments to oil and gas sales from the Company's hedging activities
     resulted in a reduction in revenues of $11,802,000 and $3,609,000 in 2000
     and 1999, respectively, and an increase in revenues of $210,000 in 1998. At
     December 31, 2000, the Company had a net unrealized hedging loss of
     $3,083,000. As of December 31, 2000 and December 31, 1999, the Company had
     no deferred net gains or net losses. As of March 9, 2001 the Company's
     hedging arrangements were as follows:



          Crude Oil:                              Daily Volume      Price per Bbl
          ----------                              ------------      ----------------------------
                                                              
          January 1, 2001 to June 30, 2001        1,750 Bbls        $28.10
          January 1, 2001 to June 30, 2001        1,000 Bbls (1)    $25.00 floor, $32.00 ceiling
          July 1, 2001 to September 30, 2001      1,000 Bbls  (1)   $25.00 floor, $30.46 ceiling

          Natural Gas:                            Daily Volume      Price per MMBTU
          ------------                            ------------      ----------------------------
          January 1, 2001 to December 31, 2001    10,000 MMBTU (1)  $4.00 floor, $6.10 ceiling


     (1)  These are "collar" hedges whereby the Company will receive the actual
          market price if the actual market price is between the floor price and
          the ceiling price. If the actual market price is below or above the
          floor or ceiling prices, the price received by the Company will be
          limited to the floor price or ceiling price, respectively.

                                      F-9



     k.   Foreign Currency Translation - The functional currency of Wiser Canada
     is the Canadian dollar. In accordance with SFAS No. 52, "Foreign Currency
     Translation," Wiser Canada's financial statements have been translated from
     Canadian dollars to U.S. dollars with the cumulative translation adjustment
     gain of $796,000 for 2000, $1,028,000 for 1999 and $1,122,000 for 1998
     classified in Stockholders' Equity.

     l.   Comprehensive Income - In 1998, the Company adopted Statement of
     Financial Accounting Standards No. 130 "Reporting Comprehensive Income"
     ("SFAS 130") which establishes standards for reporting and display of
     comprehensive income and its 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.

     m.   Recent Accounting Pronouncements - In June 1998, the Financial
     Accounting Standards Board issued SFAS No. 133 "Accounting for Derivative
     Instruments and Hedging Activities" which, as amended, is effective for all
     fiscal years beginning after June 15, 2000 (January 1, 2001 for the
     Company). SFAS No. 133 requires that derivatives be reported on the balance
     sheet at fair value and, if the derivative is not designated as a hedging
     instrument, changes in fair value must be recognized in earnings in the
     period of change. If the derivative is designated and qualifies as a hedge
     and to the extent such hedge is determined to be effective, changes in fair
     value are either offset by the change in fair value of the hedged asset or
     liability (if applicable) or reported as a component of other comprehensive
     income in the period of change, and subsequently recognized in earnings
     when the offsetting hedged transaction occurs. The change in fair value, to
     the extent the hedge is determined to be ineffective, is recorded currently
     earnings. The definition of derivatives has also been expanded to include
     contracts that require physical delivery of oil and gas if the contract
     allows for net cash settlement. The Company currently uses derivatives to
     hedge oil and gas price risk and gains or losses on such derivatives are
     recorded as adjustments to oil and gas sales. The Company uses derivatives
     to hedge oil and gas price risk and gains or losses on such derivatives
     prior to the adoption of SFAS No. 133 were recorded as adjustments to oil
     and gas sales. The Company adopted SFAS No. 133 on January 1, 2001 and its
     existing oil and gas hedging contracts were designated as cash flow hedges.
     The effective portion of the gain or loss on a cash flow hedge must be
     reported as a component of other comprehensive income and be reclassified
     into earnings in the same period or periods during which the hedged
     forecasted transaction affects earnings. The ineffective portion, if any,
     of the gain or loss on a cash flow hedge must be recognized currently in
     earnings. Based on the cash flow hedges in effect on December 31, 2000,
     derivative liabilities of approximately $3,083,000 would be recognized in
     the Company's consolidated balance sheet with an offsetting amount
     recognized in accumulated other comprehensive loss.

2.   Divestitures

     In April and May 1999, the Company entered into three separate agreements
     to sell its oil and gas properties in the Appalachia area, certain
     properties in Texas and New Mexico and virtually all of its royalty
     interests in the United States (the "Second Quarter Property Sales"). The
     Second Quarter Property Sales were closed in April and May 1999 for an
     aggregate sales price of $42,300,000, before fees and adjustments, and
     represented approximately 19% of the Company's proved reserves as of
     December 31, 1998. The Company recognized a net gain of $3,361,000 from the
     Second Quarter Property Sales and the revenues and expenses associated with
     the sold properties are included in the Company's consolidated statements
     of income through the various closing dates.

                                      F-10



3.   Long-term Debt

     a.   On May 21, 1997, the Company sold $125 million in principal amount of
          9 1/2% Senior Subordinated Notes ("2007 Notes") due May 15, 2007,
          providing net proceeds to the Company of $120,898,000. The original
          issue price was 99.718%. The Company used the net proceeds from the
          sale of the 2007 Notes to repay all outstanding bank indebtedness and
          for general corporate purposes.

          The 2007 Notes are redeemable at the option of the Company, in whole
          or in part, at any time on or after May 15, 2002 at a redemption price
          of 104.75%, plus accrued interest to the date of redemption, and
          declining at the rate of 1.583% per year to May 15, 2005 and 100%
          thereafter.

          Under the terms of the 2007 Notes, the Company must meet certain tests
          before it is able to pay cash dividends or make other restricted
          payments, incur additional indebtedness, engage in transactions with
          its affiliates, incur liens and engage in certain sale and leaseback
          arrangements. The terms of the 2007 Notes also limit the Company's
          ability to undertake a consolidation, merger or transfer of all or
          substantially all of its assets. In addition, the Company is, subject
          to certain conditions, obligated to offer to repurchase the 2007 Notes
          at par value plus accrued interest to the date of repurchase with the
          net cash proceeds of certain sales or dispositions of assets. Upon a
          change of control, as defined, the Company will be required to make an
          offer to purchase the 2007 Notes at 101% of the principal amount
          thereof, plus accrued interest to the date of purchase.

     b.   On May 10, 1999 the Company entered into a $25 million Restated Credit
          Agreement ("BankOne Revolver") with Bank One, Texas, N.A. The BankOne
          Revolver provides the Company with up to a $25 million line of credit
          through April 30, 2001. At December 31, 2000, the amount available for
          borrowing, which is based on the Company's oil and gas reserves and
          the Company's Borrowing Base at December 31, 2000 was $8 million.
          Available loan and interest options are (i) Prime Rate Loans, at the
          bank's prime interest rate and (ii) Eurodollar Loans, at LIBOR plus
          2.5%, 2.75% or 3% depending on the percentage of the Borrowing Base
          actually borrowed by the Company. The average interest rate during
          2000 under the Credit Agreement was 9.25%. The commitment fee on the
          unused Borrowing Base is 0.5%. The BankOne Revolver imposes certain
          restrictions on sales of assets, payment of dividends and incurrence
          of indebtedness and requires the Company to, among other things,
          maintain certain financial ratios and make monthly escrow deposits of
          $990,000 to fund the semi-annual interest payments on the 9 1/2%
          Senior Subordinated Notes. At December 31, 2000, restricted cash
          included $992,000 of escrow deposits which are restricted to fund the
          May 15, 2001 interest payment on the 9 1/2% Senior Subordinated Notes.
          The Company is currently negotiating a new credit facility.

     The Company paid $11,964,000, $12,993,000 and $12,375,000 in interest
     during 2000, 1999 and 1998, respectively.



     Long-term debt consists of the following (000's):                        December 31,
                                                                              ------------

   At December 31, 2000, the Company had a net operating loss ("NOL") for
   Federal income tax purposes of $18,637,000.  The majority of the NOL
   carryforwards do not expire until 2019 and the alternative minimum tax credit
   carryforwards can be carried forward indefinitely.  The tax benefits of
   carryforwards are recorded as an asset to the extent that management assesses
   the future utilization of such carryforwards as "more likely than not."  When
   the future utilization of some portion of the carryforwards is determined not
   to be "more likely than not," a valuation allowance is provided to reduce the
   recorded tax benefits from such assets.  At December 31, 2000, a valuation
   allowance of $4,455,000 was provided to reduce deferred tax assets to an
   amount equal to deferred tax liabilities.

6.  Employee Pension Plan

   The Company has a noncontributory defined benefit pension plan, which covers
   substantially all full-time employees.  Plan participants become fully vested
   after five years of continuous service.  The retirement benefit formula is
   based on the employee's earnings, length of service and age at retirement.
   Contributions required to fund plan benefits are determined according to the
   Projected Unit Credit Method.  The assets of the plan are primarily invested
   in equity and debt securities.  An amendment to the pension plan, effective
   January 1, 1993, reduced the normal retirement age from 65 years to 62 years.
   Effective December 11, 1998, the pension plan was further amended to curtail
   certain pension benefits.

7. Employee Savings Plan

   The Company has a qualified Savings Plan available to all employees. An
   employee may elect to have up to 15% of the employee's base monthly
   compensation, exclusive of other forms of special or extra compensation,
   withheld and placed in the Savings Plan account. On a monthly basis, the
   Company contributes to this account an amount equal to 50% of the employee's
   contribution, limited to 3% of the employee's base compensation. Company
   contributions to the Savings Plan were $88,000, $99,000 and $156,000, in
   2000, 1999 and 1998, respectively.

8. Business Segment Information

   In 1998, the Company adopted SFAS No. 131, "Disclosures about Segments of an
   Enterprise and Related Information" which requires reporting of financial and
   descriptive information about a company's reportable operating segments. The
   Company has identified only one operating segment, which is the exploration
   for and production of oil and gas with sales made to domestic and Canadian
   energy customers. Sales to major customers for the year ended December 31,
   2000 were $28,059,000 to Highland Energy Company, $16,367,000 to Nexen Inc.
   and $8,377,000 to EOTT Energy Operating Ltd. which represented 42%, 24% and
   13%, respectively, of the Company's total oil and gas revenues. Sales to
   major customers for the year ended December 31, 1999 were $19,345,000 to
   Highland Energy Company, $5,013,000 to CXY Energy Marketing and $4,972,000 to
   EOTT Energy Operating Ltd. which represented 41%, 11% and 10%, respectively,
   of the Company's total oil and gas revenues. Sales to major customers for the
   year ended December 31, 1998 were $20,684,000 to Highland Energy Company and
   $7,656,000 to Koch Oil Co. Ltd. which represented 34% and 13%, respectively,
   of the Company's total oil and gas revenues. The sales to Koch Oil Co. Ltd.
   accounted for approximately 55% of the Company's revenues from sales of its
   Canadian production in 1998. However, due to the nature of the oil and gas
   industry, the Company is not dependent upon any of these customers. The loss
   of any major customer would not have a material adverse impact on the
   Company's business.

   The following table summarizes the oil and gas activity of the Company by
   geographic area for the years ended December 31, 2000, 1999 and 1998.

9.  Contingencies

   The Company is a defendant in a civil action in Kentucky where the plaintiff
   has alleged damages resulting from the construction of a pipeline on the
   plaintiff's property. A judgement against the Company was awarded by a
   Circuit Court in the amount of $75,000 plus approximately $275,000 of pre-
   judgement interest for a total award of $350,000 to the plaintiff. The
   Company has appealed the Circuit Court ruling to the Kentucky Court of
   Appeals and the Company believes it is more likely than not that a the pre-
   judgement interest will be eliminated and the liability of the Company will
   be in the range of $25,000 to $75,000.

10.  Stock Compensation Plans

     Stock Options

     SFAS No. 123, "Accounting for Stock-Based Compensation," encourages but
     does not require companies to record compensation cost for stock-based
     employee compensation plans at fair value. During 1996, the Company adopted
     the disclosure provisions of SFAS No. 123. The Company continues to apply
     the accounting provisions of APB Opinion 25, "Accounting for Stock Issued
     to Employees," and related interpretations to account for stock-based
     compensation. Accordingly, compensation cost for stock options is measured
     as the excess, if any, of the quoted market price of the Company's stock at
     the date of the grant over the amount an employee must pay to acquire the
     stock.

     The Company has two stock option plans, the 1991 Stock Incentive Plan
     ("Incentive Plan") and the 1991 Non-Employee Directors' Stock Option Plan
     ("Directors' Plan"). The Incentive Plan provides for the issuance of ten-
     year options with a variable vesting period and a grant price equal to the
     fair market value at the issue date. The Directors' Plan, as amended,
     provides for the issuance of ten-year options with a six-month vesting
     period and a grant price equal to the fair market value at the issue date.

     A summary of the status of the Company's two stock option plans at December
     31, 2000, 1999 and 1998 and changes during the years then ended follows:

(1)  Weighted average per option granted.

     223,825 of the options outstanding at December 31, 2000 have exercise
     prices between $3.50 and $5, with a weighted average exercise price of
     $4.96 and a weighted average remaining contractual life of 8.3 years. All
     of the $3.50 to $5 options are currently exercisable with a weighted
     average exercise price of $4.96. 547,250 of the options outstanding at
     December 31, 2000 have exercise prices between $11 and $15, with a weighted
     average exercise price of $14.33 and a weighted average remaining
     contractual life of 5.7 years. All of the $11 to $15 options are currently
     exercisable with a weighted average exercise price of $14.33. The remaining
     340,000 options have exercise prices between $15 and $20, with a weighted
     average exercise price of $17.91 and a weighted average contractual life of
     4.3 years. 340,000 of the $15 to $20 options are currently exercisable with
     a weighted average exercise price of $17.91.

     The fair value of each option grant is estimated on the date of grant using
     the Black-Scholes option pricing model with the following weighted-average
     assumptions used for grants for both the Incentive Plan and the Directors'

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

                       December 31, 2000, 1999 and 1998


     Had compensation cost been determined consistent with SFAS No. 123, the
     Company's net income and basic earnings per share would have been reduced
     to the following pro forma amounts:




                                                                               2000       1999        1998

             Earnings (loss) per share - pro forma........................     0.37      (1.70)      (2.76)


     Because the SFAS No. 123 method of accounting has not been applied to
     options granted prior to January 1, 1995, the resulting pro forma
     compensation cost may not be representative of compensation cost to be
     expected in future years.

     Share Appreciation Rights Plan

     The Company has a share appreciation rights ("SARs") plan which authorizes
     the granting of SARs to employees of the Company. Upon exercise, SARs allow
     the holder to receive the difference between the SARs exercise price and
     the fair market value of the Company's common stock covered by the SARs on
     the exercise date. At December 31, 2000, 12,750 SARs were outstanding with
     an exercise price of $5.00 per share and 4,000 SARs were outstanding with
     an exercise price of $14.63 per share. All SARs are fully vested at
     December 31, 2000.

11.  Preferred Stock

     On December 13, 1999, the Board of Directors approved the sale of not less
     than 600,000 shares and not more than 1,000,000 shares of Series C
     Cumulative Convertible Preferred Stock ("Preferred Stock") through a
     private placement to Wiser Investment Company, LLC and its affiliates
     ("WIC") for $25 million. The sale of Preferred Stock was approved by the
     Company's shareholders on May 16, 2000, and 600,000 shares were issued to
     WIC on May 26, 2000 for $15 million, or $25 per share. WIC has the option,
     until May 25, 2001, to purchase up to an additional 400,000 shares of
     Preferred Stock for $10.0 million, or $25 per share. The Preferred Stock is
     convertible at the option of the holder into shares of the Company's common
     stock at a conversion price of $4.25 per common share, subject to customary
     adjustments. The Preferred Stock pays dividends in cash or in shares of the
     Company's common stock, at the option of the Company, at an annual rate of
     7%. The holders of the Preferred Stock have the same voting rights as the
     holders of the Company's common stock with each share of the Preferred
     Stock having one vote for each share of common stock into which it is
     convertible. The Company received $13.7 million in net proceeds from the
     sale of Preferred Stock to WIC.

     Any shares of Preferred Stock not previously converted will convert
     automatically to common stock on May 26, 2003, or whenever the market price
     of the Company's common stock exceeds $10.00 per share for a period of 60
     consecutive trading days.

     In addition, WIC acquired warrants to purchase 445,030 shares of the
     Company's common stock at $4.25 per share. If WIC fully exercises its
     option to purchase an additional 400,000 shares of Preferred Stock, WIC
     would be issued warrants to purchase an additional 296,686 shares of the
     Company's common stock at $4.25 per share. The purchase price of the
     warrants is $0.02 per warrant. The warrants are not exercisable for two
     years and will expire after seven years.

     In connection with the sale of the Preferred Stock, the Board of Directors
     has been changed to include four of the existing directors and three new
     directors designated by WIC. The transaction also affected the

     employment agreements for all four of the officers of the Company. If an
     officer's employment with the Company is terminated by either the Company
     or the officer within one year after the transaction, the Company will be
     required to make a lump-sum termination payment, as defined in the
     employment agreement, to the terminated officer. The total amount of such
     termination payments for all of the Company's officers is estimated to be
     in the range of $2.9 million to $3.1 million. In the second quarter of
     2000, three of the Company's four officers were terminated and the Company
     recognized $2.2 million of expense related to such terminations which is
     included in general and administrative expense in the Consolidated
     Statements of Income.

     In May 2000, the Company also adopted an amended and restated certificate
     of incorporation which increased the number of authorized shares of common
     stock from 20,000,000 to 30,000,000, and the number of authorized shares of
     preferred stock from 300,000 shares to 1,000,000 shares. The par value of
     the common stock was also decreased from $3.00 per share to $.01 per share.


12.  Earnings Per Share

     The Company accounts for earnings per share ("EPS") in accordance with SFAS
     No. 128, "Earnings Per Share." Under SFAS No. 128, basic EPS is computed by
     dividing net income available to common by the weighted average common
     shares outstanding without including any potentially dilutive securities.
     Diluted EPS is computed by dividing net income by the weighted average
     common shares outstanding plus, when their effect is dilutive, common stock
     equivalents consisting of stock options, warrants and convertible
     securities. Previously reported EPS were equivalent to the diluted EPS
     calculated under SFAS No. 128. Net income per share computations to
     reconcile basic and diluted net income for the years ended December 31,
     2000, 1999 and 1998, respectively, consist of the following (in thousands,
     except per share data):

13.  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., Wiser Delaware LLC, The
     Wiser Oil Company of Canada, (collectively "Wiser Canada"), The Wiser
     Marketing Company and T.W.O.C., Inc. were the Subsidiary Guarantors (the
     "Initial Subsidiary Guarantors"). Except for two 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.

     Following is summarized financial information of the Subsidiary Guarantors.
     The Company has not presented separate financial statements and other
     disclosures concerning each Subsidiary Guarantor because management has
     determined that they are not material to investors. There are no
     significant contractual restrictions on distributions from each of the
     Subsidiary Guarantors to the Company.

14. Estimated Quantities of Oil and Gas Reserves (Unaudited)

    Proved reserves are the estimated quantities of crude oil, natural gas and
    natural gas liquids, which upon analysis of geological and engineering data
    appear with reasonable certainty to be recoverable in future years from
    known reservoirs under existing economic and operating conditions. Proved
    developed reserves are proved reserves which can be expected to be recovered
    through existing wells with existing equipment and under existing operating
    conditions.

    The estimation of reserves requires substantial judgment on the part of
    petroleum engineers and may result in imprecise determinations, particularly
    with respect to new discoveries. Accordingly, it is expected that the
    estimates of reserves will change as future production and development
    information becomes available and that revisions in these estimates could be
    significant.

Standardized Measure of Discounted Future
Net Cash Flows of Proved Oil and Gas Reserves (Unaudited)

   The Company has estimated the standardized measure of discounted future net
   cash flows and changes therein relating to proved oil and gas reserves in
   accordance with the standards established by the Financial Accounting
   Standards Board through its Statement No. 69.  The estimates of future cash
   inflows are based on year-end prices.  The weighted-average year-end sales
   price used to estimate future cash inflows were: 2000 -  $25.18/BBL for oil
   and $9.72/MCF for gas, 1999 - $23.76/BBL for oil and $1.99/MCF for gas, and
   1998 - $10.39/BBL for oil and $1.98/MCF for gas.

                      Supplemental Financial Information

       For the years ended December 31, 2000, 1999 and 1998 (Unaudited)


   Estimated future production of proved reserves and estimated future
   production and development costs of proved reserves are based on year-end
   costs and economic conditions. Estimated future income tax expense is
   calculated by applying year-end statutory tax rates (adjusted for permanent
   differences and tax credits) to estimated future pretax net cash flows
   related to proved oil and gas reserves, less the tax basis of the properties
   involved.

   This standardized measure of discounted future net cash flows is an attempt
   by the Financial Accounting Standards Board to provide the users of financial
   statements with information regarding future net cash flows from proved
   reserves. However, the users of these financial statements should use extreme
   caution in evaluating this information. The assumptions required to be used
   in these computations are subjective and arbitrary. Had other equally valid
   assumptions been used, significantly different results of discounted future
   net cash flows would result. Therefore, these estimates do not necessarily
   reflect the current value of the Company's proved reserves or the current
   value of discounted future net cash flows for the proved reserves.

   The following are the Company's estimated standardized measure of discounted
   future net cash flows from proved reserves (000's):

16. Restatement

    The Company discovered an accounting error from translating Canadian dollars
    to U.S. dollars that resulted in an overstatement of net property and
    equipment and stockholders' equity in the consolidated balance sheets at
    December 31, 2000 and 1999. The overstatement of net property and equipment
    and stockholders' equity was $4,079,000 at December 31, 2000 and $3,162,000
    at December 31, 1999. Accordingly, the Company has restated its consolidated
    balance sheets at December 31, 2000 and 1999 and its consolidated statements
    of changes in stockholders' equity for the three years ended December 31,
    2000.
