PART I
Item 1. Business

The Company is a regional independent energy company engaged
primarily in the development, production and marketing of natural gas. The
Company has grown primarily through drilling and development activities,
the acquisition of natural gas producing wells and the expansion of its
natural gas marketing activities. As of December 31, 1999, the Company
operated approximately 1,800 wells located in the Appalachian and Michigan
Basins and the Rocky Mountain Region, and had net proved reserves of 101
Bcf of natural gas. The Company's wells currently produce an aggregate of
approximately 37,000 Mcf of natural gas per day, of which the Company's
share is approximately 14,500 Mcf.

The majority of the wells operated by the Company are located in the
West Virginia and Pennsylvania portions of the Appalachian Basin. The
Appalachian Basin is characterized by shallow developmental wells, which
generally have provided highly predictable drilling success rates. In
addition, because wells drilled in the Appalachian Basin are closer to the
large demand centers for natural gas in the northeastern United States,
natural gas from this area has historically commanded a price premium
relative to natural gas produced in areas such as the Gulf Coast and
Mid-Continent regions of the United States. In 1997, the Company commenced
drilling in the Antrim shale formation of the Michigan Basin and through
December 31, 1999, had drilled 183 wells in this area. In 1999 in
addition to its drilling activities, the Company purchased natural gas
producing properties. In December 1999, the Company purchased 53 net
wells in Colorado.

The Company owns Riley Natural Gas (RNG), an Appalachian Basin
natural gas marketing company, which aggregates and resells natural gas
developed by the Company and other producers. This allows the Company to
diversify its operations beyond natural gas drilling and production. RNG
has established relationships with many of the small natural gas producers
in the Appalachian Basin and has significant expertise in the natural gas
end-user market. In addition, RNG has extensive experience in the use of
hedging strategies, which the Company utilizes to reduce the financial
impact on the Company of changes in the price of natural gas.

Since 1984, the Company has sponsored limited partnerships formed to
engage in drilling operations. The Company typically retains a 20%
ownership interest in these drilling limited partnerships. In 1999, the
Company raised $36.1 million through four public drilling partnerships,
making it the sponsor of the largest public oil and gas partnership
program in the United States in that year. The drilling programs have
provided the Company with access to the capital resources necessary to
expand its drilling opportunities and to maintain the infrastructure
necessary to support such activities.

Industry Overview

Natural gas is the second largest energy source in the United States,
after liquid petroleum. The 22 Tcf of natural gas consumed in 1999
represented approximately 23% of the total energy used in the United
States. Natural gas is consumed in the United States as follows: 46% by
industrial end-users as feedstock for products such as plastic and
fertilizer or as the energy source for producing products such as glass;
21% and 14% by residential and commercial end-users, respectively, for
uses including heating, cooling and cooking; 15% by utilities for the
generation of electricity; and the remainder for transportation purposes.

The Company believes that the market for natural gas will grow in the
future. The demand for natural gas has increased due to four main factors:

- Efficiency. Relative to other energy sources, natural gas losses
during transportation from source to destination are slight,
averaging only about 9% of the natural gas energy.


-2-
- Environmentally favorable. Natural gas is the cleanest and most
environmentally safe of the fossil fuels.

- Safety. The delivery of natural gas is among the safest means of
distributing energy to customers, as the natural gas transmission
system is fixed and is located underground.

- Price. The deregulation of the natural gas industry and a
favorable regulatory environment have resulted in end-users'
ability to purchase natural gas on a competitive basis from a
greater variety of sources.

The Company believes that the foregoing factors, together with the
increased availability of natural gas as a form of energy for residential,
commercial and industrial uses, should increase the demand for natural gas
as well as create new markets for natural gas.

As local supplies of natural gas are inadequate to meet demand, the
West Coast and the Northeast import natural gas from producing areas via
interstate natural gas pipelines. The cost of transporting natural gas
from the major producing areas to markets creates a price advantage for
production located closer to the consuming region. Appalachian Basin
natural gas production enjoys two advantageous factors affecting price.
First, the Appalachian Basin is characterized by shallow development gas
wells that generally have provided highly predictable drilling success
rates of 90% to 92%, which permits a more basic approach to drilling based
on the geology unique to the area. Also, the natural gas industry in the
Appalachian Basin benefits from its proximity to the northeastern United
States.

In the early 1980's, natural gas companies began exploiting the
northern portion of Michigan's lower peninsula, when certain favorable tax
credits for natural gas development were enacted. The result of such
development was new advances in drilling technology, which made natural
gas drilling in this area profitable even after the expiration of these
tax credits. In Michigan's lower peninsula, there is an abundance of
shallow Antrim gas shale, which can provide significant reserves per well
drilled. Additionally, this area is close to certain end-user markets,
which has provided favorable premiums. With a current productive area of
nearly 2.5 million acres, Michigan has been one of the most active areas
for natural gas drilling in the United States over the past decade.

During 1998 the Company began to establish a lease position in the
Rocky Mountain producing region. The region is believed to hold
substantial undeveloped natural gas resources. Recent additions to
pipeline capacity in the region have made the area more attractive for
development. Gas from the region will generally sell for less than gas in
the Appalachian and Michigan Basins, but costs of development are expected
to be less. During 1998, the Company leased 39,500 acres of oil and gas
development rights acres in Utah, and was investigating opportunities in
several other areas. In 1999 the company drilled four unsuccessful
exploratory wells, two in Moffatt County, Colorado and two in Carter
County, Montana. In November and December 1999 the Company acquired
drilling rights to 20 locations in the Wattenberg field in Weld County,
Colorado and a 7,400 acre lease in the Grand Valley field in Garfield
County, Colorado. Prior to the end of 1999, the Company had drilled five
successful wells in the Wattenberg field and was prepared to drill its
first Grand Valley test well. Wells in both areas are generally
development wells.

Business Strategy

The Company's objective is to expand its natural gas reserves,
production and revenues through a strategy that includes the following key
elements:


-3-

Expand drilling operations. The Company has had one of the most
active drilling programs in the Northeast in the 1990's and will seek to
continue to build on the experience developed. The Company drilled 178
wells in 1999, compared to 213 for the year of 1998. The Company believes
that it will be able to drill a substantial number of new wells on its
current undeveloped leased properties. As of December 31, 1999, the
Company had 37,000 net undeveloped acres in the Michigan Basin, 28,430 net
undeveloped acres in the Appalachian Basin and 88,020 net undeveloped
acres in the Rocky Mountain Region. As drilling activity increases, the
Company benefits as its fixed costs may be spread over a larger number of
wells.

Acquire producing properties. The Company's acquisition efforts are
focused on properties that fit well within existing operations or that
help to build critical mass in areas where the Company is establishing new
operations. Acquisitions will likely offer economies in management and
administration, and therefore the Company believes that it will be able to
acquire more producing wells without incurring substantial increases in
its costs of operations.

Pursue geographic expansion. The Company has a proven ability to
drill and operate shallow natural gas wells successfully. There are a
number of areas outside the Appalachian Basin where drilling and operating
characteristics are similar to those in Appalachia. For example, since
1996, the Company expanded into the Michigan Basin, which permitted the
Company to leverage its expertise developed in the Appalachian Basin
because of the similarities in methods of drilling, depth, equipment and
operations. Moreover, reserves and production levels of two to three times
that of Appalachian levels for a similar investment more than offset
higher expected operating costs. The Company's Colorado development
projects also build on our shallow gas well operating experience. The
Company will continue to evaluate opportunities to expand geographically
on an ongoing basis.

Reduce risks inherent in natural gas development and marketing. An
integral part of the Company's strategy has been and will continue to be
to concentrate on shallow development, (rather than exploratory) drilling,
and geographical diversification to reduce risk levels associated with
natural gas and oil production. Development drilling is less risky than
exploratory drilling and is likely to generate cash returns more quickly.
The focus on shallow wells builds on the Company's knowledge and
experience, and also provides greater investment diversification than an
equal investment in a smaller number of deeper and/or more expensive
wells. Geographical diversification can help to offset possible weakness
in the natural gas market or disappointing drilling results in one area.
The Company believes that, as natural gas markets are deregulated,
successful natural gas marketing is essential to profitable operations. To
further this goal, the Company has the expertise of RNG, an experienced
natural gas marketer. The Company intends to continue to expand its
marketing capacity to keep pace with the changing natural gas industry.

Expand strategic relationships. By managing drilling programs for
itself and other investors, the Company is able to share administrative,
overhead and other costs with its partners, reducing costs for both. The
Company also is able to maintain a larger and more capable geology and
engineering staff than would be possible without partners. Other benefits
from these associations include greater buying power for drilling services
and materials, larger amounts of natural gas available to market, profits
to the Company from drilling and operating wells for partners, and greater
awareness of the Company in the investment community.

Exploration and Development Activities

The Company's development activities focus on the identification and
drilling of new productive wells and the acquisition of existing producing
wells from other producers.


-4-

Prospect Generation

The Company's staff of professional geologists is responsible for
identifying areas with potential for economic production of natural gas.
The Company's team of professional geologists has decades of experience
drilling successful, economically feasible natural gas wells. The
geological team utilizes results from logs and other tools to evaluate
existing wells and to predict the location of attractive new gas reserves.
To further this process, the Company has collected and continues to
collect logs, core data, production information and other raw data
available from state and private agencies, other companies and individuals
actively drilling in the regions being evaluated. From this information
the geologists develop models of the subsurface structures and
stratigraphy that are used to predict areas with above-average prospects
for economic development.

On the basis of these models, the geologists instruct the Company's
land department to obtain available natural gas leaseholds in these
prospective areas. These leases are then obtained, if possible, by the
Company's land department or contract landmen under the direction of the
Company's land manager. In most cases, the Company pays a lease bonus and
annual rental payments, converting, upon initiation of production, to a
12.5% royalty on gross production revenue in return for obtaining the
leases. In some instances of particularly attractive properties,
additional overriding royalty payments may be made to third parties or
royalty owners. As of December 31, 1999, the Company had a total
leasehold inventory of approximately 247,140 gross acres and 246,710 net
acres. See--"Properties--Natural Gas Leases."

Drilling Activities

When prospects have been identified and leased, the Company develops
these properties by drilling wells. In 1999, the Company drilled a total
of 178 wells, of which 13 were dry holes. Typically, the Company will act
as driller-operator for these prospects, entering into contracts with
partnerships, including Company-sponsored partnerships, and other entities
that are interested in exploration or development of the prospects. The
Company generally retains an interest in each well it drills. See
"Financing of Drilling Activities."

Much of the work associated with drilling, completing and connecting
wells, including drilling, fracturing, logging and pipeline construction,
is performed by subcontractors specializing in those operations, as is
common in the industry. A large part of the material and services used by
the Company in the development process is acquired through competitive
bidding by approved vendors. The Company also directly negotiates rates
and costs for services and supplies when conditions indicate that such an
approach is warranted. As the prices paid to the Company by its investor
partners for the Company's services are frequently fixed before the wells
are drilled or are determined solely on the well depth, the Company is
subject to the risk that prices of goods or services used in the
development process could increase, rendering its contracts with its
investor partners less profitable or unprofitable. In addition, problems
encountered in the process can substantially increase development costs,
sometimes without recourse for the Company to recover its costs from its
partners. To minimize these risks, the Company seeks to lock in its
development costs in advance of drilling and, when possible, at the time
of negotiation and execution of its investor partnership agreements.

Acquisitions of Producing Properties

In addition to drilling new wells, the Company continues to pursue
opportunities to purchase existing wells from other producers and greater
ownership interests in the wells it operates. Generally, outside interests
purchased include a majority interest in the wells and well operations.


-5-

During 1998 the Company purchased an 80% interest in 122 producing wells
located in Pennsylvania from Pemco Gas, Inc. and a 100% working interest
in 13 producing wells in Michigan, as well as certain well interests in
its Company sponsored partnerships. In 1999, the Company purchased a 100%
working interest in 53 producing wells in the D-J Basin of Colorado which
added 3.6 Bcf of natural gas and 370,000 barrels of oil to the Company's
reserves. Also purchased in 1999 were certain well interests in its
Company sponsored partnerships.

Production

The following table shows the Company's net production in Bbls of
crude oil and in Mcf of natural gas and the costs and weighted average
selling prices thereof, for the last five years.

(1) Production as shown in the table is net to the Company and is
determined by multiplying the gross production volume of properties
in which the Company has an interest by the percentage of the
leasehold or other property interest owned by the Company.

(2) A ratio of energy content of natural gas and oil (six Mcf of natural
gas equals one barrel of oil) was used to obtain a conversion factor
to convert oil production into equivalent Mcfs of natural gas.

(3) Production costs represent oil and gas operating expenses as
reflected in the financial statements of the Company.

Well Operations

The Company currently operates approximately 1,538 natural gas wells
in the Appalachian Basin, 200 wells in the Michigan Basin and 58 wells in
the Rocky Mountain Region. The Company's ownership interest in these wells
ranges from 0% to 100%, and, on average, the Company has an approximate
48% ownership interest in the wells it operates. Currently these wells
produce an aggregate of about 37,000 Mcf of natural gas per day, including
the Company's share of 14,500 Mcf per day.

The Company is paid a monthly operating charge for each well it
operates for outside owners. The rate is competitive with rates charged by
other operators in the area. The charge covers monthly operating and
accounting costs, insurance and other recurring costs. The Company may
also receive additional compensation for special non-recurring activities,
such as reworks and recompletions.







-6-

Transportation

Natural gas wells are connected by pipelines to natural gas markets.
Over the years, the Company has developed extensive gathering systems in
its areas of operations. The Company also continues to construct new
trunklines as necessary to provide for the marketing of natural gas being
developed from new areas and to enhance or maintain its existing systems.

The Company is paid a transportation fee for natural gas that is moved by
other producers through these pipeline systems. In many cases the Company
has been able to receive higher natural gas prices as a result of its
ability to move natural gas to more attractive markets through this
pipeline system, to the benefit of both the Company and its investor
partners.

The Company has an Ohio subsidiary, Paramount Natural Gas Company
("PNG"), which commenced operations in October 1992 as a regulated Ohio
distribution utility. As a utility, PNG has been able to connect new
customers, and the Company is able to compete for the natural gas markets
of these customers by transporting natural gas through the PNG system. The
majority of PNG's throughput is attributable to natural gas transported
for the Company and industrial customers for a transportation tariff, with
the balance being sales to residential, commercial and industrial
customers.

Drilling Activity

The following table summarizes the Company's development drilling
activity for the years ended December 31, 1995, 1996, 1997, 1998 and 1999.
There is no correlation between the number of productive wells completed
during any period and the aggregate reserves attributable to those wells.
The Company's exploratory wells drilled in the past five years consist of
one dry hole (0.19 net) drilled in 1998 and five dry holes (2.44 net)
drilled in 1999.

Reserves

All of the Company's oil and natural gas reserves are located in the
United States. The Company's approximate net proved reserves were
estimated by Wright & Company, Inc. independent petroleum engineers
("Wright & Company"), to be 101,245,000 Mcf of natural gas and 1,154,000
Bbls of oil at December 31, 1999; 80,819,000 Mcf of natural gas and 29,000
Bbls of oil at December 31, 1998; and 57,243,000 Mcf of natural gas and
45,000 Bbls of oil at December 31, 1997.

The Company's approximate net proved developed reserves were
estimated, by Wright & Company to be 82,628,000 Mcf of natural gas and
798,000 Bbls of oil at December 31, 1999; 64,562,000 Mcf of natural gas
and 29,000 Bbls of oil at December 31, 1998; and 42,411,000 Mcf of natural
gas and 45,000 Bbls of oil at December 31, 1997.

No major discovery or other favorable or adverse event that would
cause a significant change in estimated reserves is believed by the
Company to have occurred since December 31, 1999. Reserves cannot be
measured exactly, as reserve estimates involve subjective judgment. The
estimates must be reviewed periodically and adjusted to reflect additional
information gained from reservoir performance, new geological and
geophysical data and economic changes.

The standardized measure of discounted future net cash flows
attributable to the Company's proved oil and gas reserves, giving effect
to future estimated income tax expenses, was estimated by Wright & Company
in 1999, 1998 and 1997 to be $58.5 million as of December 31, 1999, $30.2
million as of December 31, 1998 and $27.9 million as of December 31, 1997.
These amounts are based on year-end prices at the respective dates. The
values expressed are estimates only, and may not reflect realizable values
or fair market values of the natural gas and oil ultimately extracted and
recovered. The standardized measure of discounted future net cash flows
may not accurately reflect proceeds of production to be received in the
future from the sale of natural gas and oil currently owned and does not
necessarily reflect the actual costs that would be incurred to acquire
equivalent natural gas and oil reserves.

Net Proved Natural Gas and Oil Reserves

The proved reserves of natural gas and oil of the Company as
estimated by Wright & Company at December 31, 1999 are set forth below.
These reserves have been prepared in compliance with the rules of the
Securities and Exchange Commission (the "SEC") based on year-end prices.
An analysis of the change in estimated quantities of natural gas and oil

Standardized Measure of Discounted Future Net Cash Flows and Changes
Therein Relating to Proved Natural Gas and Oil Reserves

Summarized in the following table is information for the Company
with respect to the standardized measure of discounted future net cash
flows relating to proved natural gas and oil reserves. Future cash
inflows are computed by applying year-end prices of natural gas and oil
relating to the Company's proved reserves to year-end quantities of those
reserves. Future production, development, site restoration and
abandonment costs are derived based on current costs, assuming
continuation of existing economic conditions. Future income tax expenses
are computed by applying the statutory rate in effect at December 31, 1999
to the future pretax net cash flows, less the tax basis of the properties,
and gives effect to permanent differences, tax credits and allowances
related to the properties.


December 31, 1999

Future estimated cash flows $307,816,000
Future estimated production and development costs (129,557,000)
Future estimated income tax expense (39,930,000)
Future net cash flows 138,329,000
10% annual discount for estimated
timing of cash flows (79,875,000)
Standardized measure of discounted
future estimated net cash flows $ 58,454,000

-9-
The following table summarizes the principal sources of change in
the standardized measure of discounted future estimated net cash flows
from January 1, 1999 through December 31, 1999:


Sales of oil and natural gas production,
net of production costs $(6,206,000)
Net changes in prices and production costs 29,547,000
Extensions, discoveries and improved recovery,
less related cost 39,653,000
Dispositions to partnerships (6,152,000)
Acquisitions 31,915,000
Development costs incurred during the period 17,168,000
Revisions of previous quantity estimates (4,944,000)
Changes in estimated income taxes (19,608,000)
Changes in discount (39,463,000)
Changes in production rate (timing) and other (13,650,000)
$ 28,260,000


The foregoing data should not be viewed as representing the expected
cash flow from, or current value of, existing proved reserves, as the
computations are based on a large number of estimates and arbitrary
assumptions. Reserve quantities cannot be measured with precision, and
their estimation requires many judgmental determinations and frequent
revisions. The required projection of production and related expenditures
over time requires further estimates with respect to pipeline
availability, rates of demand and governmental control. Actual future
prices and costs are likely to be substantially different from the current
prices and costs utilized in the computation of reported amounts. Any
analysis or evaluation of the reported amounts should give specific
recognition to the computational methods and the limitations inherent
therein.

Substantially all of the Company's natural gas and oil reserves have
been mortgaged or pledged as security for the Company's credit agreement.

Title to Properties

The Company believes that it holds good and indefeasible title to
its properties, in accordance with standards generally accepted in the
natural gas industry, subject to such exceptions stated in the opinion of
counsel employed in the various areas in which the Company conducts its
exploration activities, which exceptions, in the Company's judgment, do
not detract substantially from the use of such property. As is customary
in the natural gas industry, only a perfunctory title examination is
conducted at the time the properties believed to be suitable for drilling
operations are acquired by the Company. Prior to the commencement of
drilling operations, an extensive title examination is conducted and
curative work is performed with respect to defects which the Company deems

-10-
to be significant. A title examination has been performed with respect to
substantially all of the Company's producing properties. No single
property owned by the Company represents a material portion of the
Company's holdings. The Company's properties are subject to customary
royalty interests, liens incident to operating agreements, liens for
current taxes and other burdens which the Company believes do not
materially interfere with the use of or affect the value of such
properties.

The properties owned by the Company are subject to royalty,
overriding royalty and other outstanding interests customary in the
industry. The properties are also subject to burdens such as liens
incident to operating agreements, current taxes, development obligations
under natural gas and oil leases, farm-out arrangements and other
encumbrances, easements and restrictions. The Company does not believe
that any of these burdens will materially interfere with the use of the
properties.

Natural Gas Sales

Natural gas is sold by the Company under contracts with terms
ranging from one month to three years. Virtually all of the Company's
contract pricing provisions are tied to a market index, with certain
adjustments based on, among other factors, whether a well delivers to a
gathering or transmission line, quality of natural gas and prevailing
supply and demand conditions, so that the price of the natural gas
fluctuates to remain competitive with other available natural gas
supplies. As a result, the Company's revenues from the sale of natural
gas will suffer if market prices decline and benefit if they increase. The
Company believes that the pricing provisions of its natural gas contracts
are customary in the industry.

The Company sells its natural gas to industrial end-users and
utilities. No customer accounted for more than 10.0% of total revenues in
1999. One customer, Hope Gas, Inc., a regulated public utility ("Hope
Gas"), accounted for 12.6% of the Company's revenues from oil and gas
sales (5.4% of total revenues) in 1998 and 26.6% of the Company's revenues
from oil and gas sales (12.0% of total revenues) in 1997. The Company and
Hope Gas were parties to a Pipeline Purchase Agreement, pursuant to which
agreement the Company delivered to Hope Gas, upon demand, minimum
quantities of natural gas (4,500 dth per day delivered directly to Hope
Gas's pipelines and 11,000 dth per day for total deliveries including both
direct and transferred volumes). The Company and Hope Gas were also
parties to a Master Gas Purchase Agreement, which expired on May 31, 1999,
pursuant to which the Company offered to Hope Gas all volumes of natural
gas available at specific points of delivery, up to the minimum delivery
requirements of the Pipeline Purchase Agreement. No other single purchaser
of the Company's natural gas accounted for 10% or more of the Company's
total revenues during 1999, 1998 or 1997.

At December 31, 1999, natural gas produced by the Company sold at
prices per Mcf ranging from $0.90 to $4.35, depending upon well location,
the date of the sales contract and whether the natural gas was sold in
interstate or intrastate commerce. The weighted net average price of
natural gas sold by the Company during 1999 was $2.46 per Mcf.

In general, the Company, together with its marketing subsidiary,
RNG, has been and expects to continue to be able to produce and sell
natural gas from its wells without curtailment by providing natural gas to
purchasers at competitive prices. Open access transportation on the
country's interstate pipeline system has greatly increased the range of
potential markets. Whenever feasible the Company allows for multiple
market possibilities from each of its gathering systems, while seeking the
best available market for its natural gas at any point in time.



-11-

Natural Gas Marketing

The Company's natural gas marketing activities involve the
aggregation and reselling of natural gas produced by the Company and
others. The Company believes that, as natural gas markets are deregulated,
successful natural gas marketing is essential to profitable operations. A
variety of factors affect the market for natural gas, including the
availability of other domestic production, natural gas imports, the
availability and price of alterative fuels, the proximity and capacity of
natural gas pipelines, general fluctuations in the supply and demand for
natural gas and the effects of state and federal regulations on natural
gas production and sales. The natural gas industry also competes with
other industries in supplying the energy and fuel requirements of
industrial, commercial and individual customers.

In 1996, the Company acquired RNG, an Appalachian Basin natural gas
marketing company that specializes in the acquisition and aggregation of
Appalachian Basin gas production. The owner/managers and employees of RNG
joined the Company, and RNG's operations were relocated to the Company's
headquarters. RNG markets natural gas produced by the Company and also
purchases natural gas from other producers and resells to utilities, end
users or other marketers. The employees of RNG have extensive knowledge of
the natural gas market in the Appalachian region. Such knowledge assists
the Company in maximizing its prices as it markets natural gas from
Company-operated wells. RNG and its management also brought to the Company
specific knowledge and relationships with many producers in the
Appalachian Basin region. Paramount Transmission Corporation ("PTC"), an
Ohio subsidiary of the Company, focuses its efforts on the marketing of
Ohio natural gas production to commercial and industrial end-users.

In West Virginia, Pennsylvania, Michigan and Colorado, the Company
markets natural gas from its own wells and wells operated for its
investment partnerships. The gas is marketed to natural gas utilities,
pipelines and industrial and commercial customers, either directly through
the Company's gathering system, or utilizing transportation services
provided by regulated interstate pipeline companies.

Hedging Activities

The Company utilizes commodity-based derivative instruments as
hedges to manage a portion of its exposure to price volatility stemming
from its natural gas sales and marketing activities. These instruments
consist of NYMEX-traded natural gas futures and option contracts. The
contracts hedge committed and anticipated natural gas purchases and sales,
generally forecasted to occur within a three- to twelve-month period.
Company policy prohibits the use of natural gas futures or options for
speculative purposes and permits utilization of hedges only if there is an
underlying physical position.

The Company has extensive experience with the use of financial
hedges to reduce the risk and impact of natural gas price changes. These
hedges are used to coordinate fixed and variable priced purchases and
sales and to "lock in" fixed prices from time to time for the Company's
share of production. In order for future contracts to serve as effective
hedges, there must be sufficient correlation to the underlying hedged
transaction. While hedging can help provide price protection if spot
prices drop, hedges can also limit upside potential.

Despite the measures taken by the Company to attempt to control
price risk, the Company remains subject to price fluctuations for natural
gas sold in the spot market. The Company continues to evaluate the
potential for reducing these risks by entering into hedge transactions. In
addition, the Company may also close out any portion of hedges that may
exist from time to time. As of December 31, 1999, there were 182 existing
hedge positions representing 1,820,000 Mmbtu.



-12-

Financing of Drilling Activities

The Company conducts development drilling activities for its own
account and for other investors. In 1984, the Company began sponsoring
private drilling limited partnerships, and, in 1989, the Company began to
register the partnership interests offered under public drilling programs
with the SEC. The Company's public partnerships had $36.1 million in
subscriptions in 1999. Funds received pursuant to drilling contracts were
$40.9 million in 1998 and $35.5 million in 1997. The Company generally
invests, as its equity contribution to each drilling partnership, an
additional sum approximating 20% of the aggregate subscriptions received
for that particular drilling partnership. As a result, the Company is
subject to substantial cash commitments at the closing of each drilling
partnership. The funds received from these programs are restricted to use
in future drilling operations. While funds were received by the Company
pursuant to drilling contracts in the years indicated, the Company
recognizes revenues from drilling operations on the percentage of
completion method as the wells are drilled, rather than when funds are
received. Most of the Company's drilling and development funds now are
received from partnerships in which the Company serves as managing general
partner. However, because wells produce for a number of years, the Company
continues to serve as operator for a large number of unaffiliated parties.
In addition to the partnership structure, the Company also utilizes joint
venture arrangements for financing drilling activities.

The financing process begins when the Company enters into a
development agreement with an investor partner, pursuant to which the
Company agrees to assign its rights in the property to be drilled to the
partnership or other entity. The partnership or other entity thereby
becomes owner of a working interest in the property.

The Company's development contracts with its investor partners have
historically taken many different forms. Generally the agreements can be
classified as on a "footage-based" rate, whereby the Company receives
drilling and completion payments based on the depth of the well;
"cost-plus," in which the Company is reimbursed for its actual cost of
drilling plus some additional amount for overhead and profit; or
"turnkey," in which a specified amount is paid for drilling and another
amount for completion. As part of the compensation for its services, the
Company also has received some interest in the production from the well in
the form of an overriding royalty interest, working interest or other
proportionate share of revenue or profits. The Company's development
contracts may provide for a combination of several of the foregoing
payment options. Basic drilling and completion operations are performed
on a footage-based rate, with leases and gathering pipelines being
contributed at Company cost. The Company may also purchase a working
interest in the subject properties.

The level of the Company's drilling and development activity is
dependent upon the amount of subscriptions in its public drilling
partnerships and investments from other partnerships or other joint
venture partners. The use of partnerships and similar financing structures
enables the Company to diversify its holdings, thereby reducing the risks
to its development investments. Additionally, the Company benefits through
such arrangements by its receipt of fees for its management services
and/or through an increased share in the revenues produced by the
developed properties. The Company believes that investments in drilling
activities, whether through Company-sponsored partnerships or other
sources, are influenced in part by the favorable treatment that such
investments enjoy under the federal income tax laws. No assurance can be
given that the Company will continue to have access to funds generated
through these financing vehicles.






-13-

Oil Production

Before 1980, the Company generated a significant portion of its
revenues from oil production. However, the Company made a strategic
decision to concentrate its development efforts on natural gas production
and most of the Company's current oil production is associated with
natural gas production. The Company's current production of oil is from
wells located in Tennessee, Ohio, West Virginia and Colorado. In 1999,
its share of oil production is about 8,000 barrels. The Company's
acquisition in December 1999 of 53 wells in Colorado, and ongoing
development activities in Colorado and Michigan are resulting in a
significant increase in oil production and reserves. At the end of 1999
oil was about 6% of the Company's total equivalent reserves. The Company
is currently able to sell all the oil that it can produce under existing
sales contracts with petroleum refiners and marketers. The Company does
not refine any of its oil production. The Company's crude oil production
is sold to purchasers at or near the Company's wells under short-term
purchase contracts at prices and in accordance with arrangements which are
customary in the oil industry. No single purchaser of the Company's crude
oil accounted for 10% or more of the Company's revenues from oil and gas
sales in 1999, 1998 or 1997. At December 31, 1999, oil produced by the
Company sold at prices ranging from $21.75 to $24.57 per barrel, depending
upon the location and quality of oil. In 1999, the weighted net average
price per barrel of oil sold by the Company was $18.75.

Oil production is subject to many of the same operating hazards and
environmental concerns as natural gas production, but is also subject to
the risk of oil spills. Federal regulations require certain owners or
operators of facilities that store or otherwise handle oil, such as the
Company, to procure and implement spill prevention, control, counter-
measures and response plans relating to the possible discharge of oil into
surface waters. The Oil Pollution Act of 1990 ("OPA") subjects owners of
facilities to strict joint and several liability for all containment and
cleanup costs and certain other damages arising from oil spills.
Noncompliance with OPA may result in varying civil and criminal penalties
and liabilities. Operations of the Company are also subject to the Federal
Clean Water Act and analogous state laws relating to the control of water
pollution, which laws provide varying civil and criminal penalties and
liabilities for release of petroleum or its derivatives into surface
waters or into the ground.

Governmental Regulation

The Company's business and the natural gas industry in general are
heavily regulated. The availability of a ready market for natural gas
production depends on several factors beyond the Company's control. These
factors include regulation of natural gas production, federal and state
regulations governing environmental quality and pollution control, the
amount of natural gas available for sale, the availability of adequate
pipeline and other transportation and processing facilities and the
marketing of competitive fuels. State and federal regulations generally
are intended to prevent waste of natural gas, protect rights to produce
natural gas between owners in a common reservoir and control contamination
of the environment. Pipelines are subject to the jurisdiction of various
federal, state and local agencies. The Company takes the steps necessary
to comply with applicable regulations both on its own behalf and as part
of the services it provides to its investor partnerships. The Company
believes that it is in substantial compliance with such statutes, rules,
regulations and governmental orders, although there can be no assurance
that this is or will remain the case. The following discussion of the
regulation of the United States natural gas industry is not intended to
constitute a complete discussion of the various statutes, rules,
regulations and environmental orders to which the Company's operations may
be subject.




-14-

Regulation of Natural Gas Exploration and Production

The Company's natural gas operations are subject to various types of
regulation at the federal, state and local levels. Prior to commencing
drilling activities for a well, the Company must procure permits and/or
approvals for the various stages of the drilling process from the
applicable state and local agencies in the state in which the area to be
drilled is located. Such permits and approvals include those for the
drilling of wells, and such regulation includes maintaining bonding
requirements in order to drill or operate wells and regulating the
location of wells, the method of drilling and casing wells, the surface
use and restoration of properties on which wells are drilled, the plugging
and abandoning of wells and the disposal of fluids used in connection with
operations. The Company's operations are also subject to various
conservation laws and regulations. These include the regulation of the
size of drilling and spacing units or proration units and the density of
wells which may be drilled and the unitization or pooling of natural gas
properties. In this regard, some states allow the forced pooling or
integration of tracts to facilitate exploration while other states rely
primarily or exclusively on voluntary pooling of lands and leases. In
areas where pooling is voluntary, it may be more difficult to form units,
and therefore, more difficult to develop a project if the operator owns
less than 100% of the leasehold. In addition, state conservation laws
establish maximum rates of production from natural gas wells, generally
prohibit the venting or flaring of natural gas and impose certain
requirements regarding the ratability of production. The effect of these
regulations may limit the amount of natural gas the Company can produce
from its wells and may limit the number of wells or the locations at which
the Company can drill. The regulatory burden on the natural gas industry
increases the Company's costs of doing business and, consequently, affects
its profitability. In as much as such laws and regulations are
frequently expanded, amended and reinterpreted, the Company is unable to
predict the future cost or impact of complying with such regulations.

Regulation of Sales and Transportation of Natural Gas

Historically, the transportation and sale for resale of natural gas
in interstate commerce have been regulated pursuant to the Natural Gas Act
of 1938, the Natural Gas Policy Act of 1978 (the "NGPA") and the
regulations promulgated thereunder by FERC. Maximum selling prices of
certain categories of natural gas sold in "first sales," whether sold in
interstate or intrastate commerce, were regulated pursuant to the NGPA.
The Natural Gas Wellhead Decontrol Act (the "Decontrol Act") removed, as
of January 1, 1993, all remaining federal price controls from natural gas
sold in "first sales" on or after that date. 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 natural gas liquids can currently be made at market prices, Congress
could reenact price controls in the future.

The Company's sales of natural gas are affected by the availability,
terms and cost of transportation. The price and terms for access to
pipeline transportation are subject to extensive regulation. In recent
years, FERC has undertaken various initiatives to increase competition
within the natural gas industry. As a result of initiatives like FERC
Order No.636, issued in April 1992, the interstate natural gas
transportation and marketing system has been substantially restructured to
remove various barriers and practices that historically limited
non-pipeline natural gas sellers, including producers, from effectively
competing with interstate pipelines for sales to local distribution
companies and large industrial and commercial customers. The most
significant provisions of Order No.636 require that interstate pipelines
provide transportation separate or "unbundled" from their sales service,
and require that pipelines provide firm and interruptible transportation
service on an open access basis that is equal for all natural gas
suppliers. In many instances, the result of Order No.636 and related
initiatives have been to substantially reduce or eliminate the interstate

-15-


pipelines' traditional role as wholesalers of natural gas in favor of
providing only storage and transportation services. Another effect of
regulatory restructuring is the greater transportation access available on
interstate pipelines. In some cases, producers and marketers have
benefitted from this availability. However, competition among suppliers
has greatly increased and traditional long-term producer-pipeline
contracts are rare. Furthermore, gathering facilities of interstate
pipelines are no longer regulated by FERC, thus allowing gatherers to
charge higher gathering rates.

Additional proposals and proceedings that might affect the natural
gas industry are pending before Congress, FERC, state commissions and the
courts. The natural gas industry historically has been very heavily
regulated; therefore, there is no assurance that the less stringent
regulatory approach recently pursued by FERC and Congress will continue.
The Company cannot determine to what extent future operations and earnings
of the Company will be affected by new legislation, new regulations, or
changes in existing regulation, at federal, state or local levels.

Environmental Regulations

The Company's operations are subject to numerous laws and
regulations governing the discharge of materials into the environment or
otherwise relating to environmental protection. Public interest in the
protection of the environment has increased dramatically in recent years.
The trend of more expansive and stricter environmental legislation and
regulations could continue. To the extent laws are enacted or other
governmental action is taken that restricts drilling or imposes
environmental protection requirements that result in increased costs to
the natural gas industry in general, the business and prospects of the
Company could he adversely affected.

The Company generates wastes that may be subject to the Federal
Resource Conservation and Recovery Act ("RCRA") and comparable state
statutes. The U.S. Environmental Protection Agency ("EPA") 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 operations that are currently exempt from treatment 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.

The Company currently owns or leases numerous properties that for
many years have been used for the exploration and production of oil and
natural gas. Although the Company believes that it has utilized good
operating and waste disposal practices, prior owners and operators of
these properties may not have utilized similar practices, and hydrocarbons
or other wastes may have been disposed of or released on or under the
properties owned or leased by the Company or on or under locations where
such wastes have been taken for disposal. These properties and the wastes
disposed thereon may be subject to the Comprehensive Environmental
Response, Compensation and Liability Act ("CERCLA"), RCRA and analogous
state laws as well as state laws governing the management of oil and
natural gas wastes. Under such laws, the Company could be required to
remove or remediate previously disposed wastes (including wastes disposed
of or released by prior owners or operators) or property contamination
(including groundwater contamination) or to perform remedial plugging
operations to prevent future contamination.

CERCLA 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 of or arranged for the disposal of the
hazardous substances found at the site. Persons who are or were
responsible for release of hazardous substances under CERCLA may be
subject to joint and several liability for the costs of cleaning up the

-16-

hazardous substances that have been released into the environment and for
damages to natural resources, and it is not uncommon for neighboring
landowners and other third parties to file claims for personal injury and
property damage allegedly caused by the hazardous substances released into
the environment.

The Company's operations may be subject to the Clean Air Act ("CAA")
and comparable state and local requirements. Amendments to the CAA were
adopted in 1990 and contain provisions that may result in the gradual
imposition of certain pollution control requirements with respect to air
emissions from the operations of the Company. The EPA and states have been
developing regulations to implement these requirements. The Company may be
required to incur certain capital expenditures in the next several years
for air pollution control equipment in connection with maintaining or
obtaining operating permits and approvals addressing other air
emission-related issues.

The Company's expenses relating to preserving the environment during
1999 were not significant in relation to operating costs and the Company
expects no material change in 2000. Environmental regulations have had no
materially adverse effect on the Company's operations to date, but no
assurance can be given that environmental regulations will not, in the
future, result in a curtailment of production or otherwise have a
materially adverse effect on the Company's business, financial condition
or results of operations.

As a matter of corporate policy and commitment, the Company attempts
to minimize the adverse environmental impact of all its operations. For
example, during 1999, the Company was one of the most active drilling
companies in the northeast. Even with this level of activity, the Company
was able to maintain a high level of environmental sensitivity. During the
1990's, the Company has been a nine-time recipient of the West Virginia
Department of Environmental Protection's top award in recognition of the
quality of the Company's environmental and reclamation work in its
drilling activities.

Utility Regulation

PNG, which is an Ohio public utility, is subject to regulation by
the Public Utilities Commission of Ohio in virtually all of its
activities, including pricing and supply of services, addition of and
abandonment of service to customers, design and construction of
facilities, and safety issues.

Operating Hazards and Insurance

The Company's exploration and production operations include a
variety of operating risks, including the risk of fire, explosions,
blowouts, craterings, pipe failure, casing collapse, abnormally pressured
formations, and environmental hazards such as gas leaks, ruptures and
discharges of toxic gas, the occurrence of any of which could result in
substantial losses to the Company due to injury and loss of life, severe
damage to and destruction of property, natural resources and equipment,
pollution and other environmental damage, clean-up responsibilities,
regulatory investigation and penalties and suspension of operations. The
Company's pipeline, gathering and distribution operations are subject to
the many hazards inherent in the natural gas industry. These hazards
include damage to wells, pipelines and other related equipment, and
surrounding properties caused by hurricanes, floods, fires and other acts
of God, inadvertent damage from construction equipment, leakage of natural
gas and other hydrocarbons, fires and explosions and other hazards that
could also result in personal injury and loss of life, pollution and
suspension of operations.





-17-

Any significant problems related to its facilities could adversely
affect the Company's ability to conduct its operations. In accordance with
customary industry practice, the Company maintains insurance against some,
but not all, potential risks; however, there can be no assurance that such
insurance will be adequate to cover any losses or exposure for liability.
The occurrence of a significant event not fully insured against could
materially adversely affect the Company's operations and financial
condition. The Company cannot predict whether insurance will continue to
be available at premium levels that justify its purchase or whether
insurance will be available at all.

Competition

The Company believes that its exploration, drilling and production
capabilities and the experience of its management generally enable it to
compete effectively. The Company encounters competition from numerous
other natural gas companies, drilling and income programs and partnerships
in all areas of its operations, including drilling and marketing natural
gas and obtaining desirable natural gas leases. Many of these competitors
possess larger staffs and greater financial resources than the Company,
which may enable them to identify and acquire desirable producing
properties and drilling prospects more economically. The Company's ability
to explore for natural gas prospects and to acquire additional properties
in the future depends upon its ability to conduct its operations, to
evaluate and select suitable properties and to consummate transactions in
this highly competitive environment. The Company competes with a number of
other companies which offer interests in drilling partnerships with a wide
range of investment objectives and program structures. Competition for
investment capital for both public and private drilling programs is
intense. The Company also faces intense competition in the marketing of
natural gas from competitors including other producers as well as
marketing companies. Also, international developments and the possible
improved economics of domestic natural gas exploration may influence other
oil companies to increase their domestic natural gas exploration.
Furthermore, competition among natural gas companies for favorable natural
gas prospects can be expected to continue, and it is anticipated that the
cost of acquiring natural gas properties may increase in the future.
Factors affecting competition in the natural gas industry include price,
location, availability, quality and volume of natural gas. The Company
believes that it can compete effectively in the natural gas industry on
each of the foregoing factors. Nevertheless, the Company's business,
financial condition or results of operations could be materially adversely
affected by competition.

Employees

As of December 31, 1999, the Company had 91 employees, including 13
in finance, 7 in administration, 14 in exploration and development, 52 in
production and 5 in natural gas marketing. The Company's engineers,
supervisors and well tenders are generally responsible for the day-to-day
operation of wells and pipeline systems. In addition, the Company retains
subcontractors to perform drilling, fracturing, logging, and pipeline
construction functions at drilling sites. The Company's employees act as
supervisors of the subcontractors.

The Company's employees are not covered by a collective bargaining
agreement. The Company considers relations with its employees to be
excellent.





-18-

Facilities

The Company owns and occupies three buildings in Bridgeport, West
Virginia, two of which serve as the Company's headquarters and one which
serves as a field operating site. The Company also owns a field operating
building in Gilmer County, West Virginia. The Company leases field
operating offices in Pennsylvania, Michigan, Colorado, and Ohio under
operating leases. The Company believes that its current facilities are
sufficient for its current and anticipated operations.

Item 3. Legal Proceedings

From time to time the Company is a party to various legal
proceedings in the ordinary course of business. The Company is not
currently a party to any litigation that it believes would materially
affect the Company's business, financial condition or results of
operations.

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

No matters were submitted to a vote of security holders during the

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

Safe Harbor Statement Under the Private Securities
Litigation Reform Act of 1995

Statements, other than historical facts, contained in this Annual
Report on Form 10-K, including statements of estimated oil and gas
production and reserves, drilling plans, future cash flows, anticipated
capital expenditures and Management's strategies, plans and objectives, are
"forward looking statements" within the meaning of Section 27A of the
Securities Act of 1933, as amended, and Section 21E of the Securities
Exchange Act of 1934, as amended. Although the Company believes that its
forward looking statements are based on reasonable assumptions, it cautions
that such statements are subject to a wide range of risks and uncertainties
incident to the exploration for, acquisition, development and marketing of
oil and gas, and it can give no assurance that its estimates and
expectations will be realized. Important factors that could cause actual
results to differ materially from the forward looking statements include,
but are not limited to, changes in production volumes, worldwide demand, and
commodity prices for petroleum natural resources; the timing and extent of
the Company's success in discovering, acquiring, developing and producing
oil and gas reserves; risks incident to the drilling and operation of oil
and gas wells; future production and development costs; the effect of
existing and future laws, governmental regulations and the political and
economic climate of the United States; the effect of hedging activities; and
conditions in the capital markets. Other risk factors are discussed
elsewhere in this Form 10-K.

Results of Operations

Year Ended December 31, 1999 Compared with December 31, 1998

Revenues. Total revenues for the year ended December 31, 1999 were
$96.8 million compared to $83.0 million for the year ended December 31,
1998, an increase of approximately $13.8 million, or 16.6%. Drilling
revenues for the year ended December 31, 1999 were $42.1 million compared to
$40.4 for the year ended December 31, 1998, an increase of approximately
$1.7 million, or 4.2%. Such increase was due to an increase in drilling and
completion activities, which was a direct result of an increase in drilling
funds from the Company's public drilling programs. Oil and gas sales for
the year ended December 31, 1999 were $47.0 million compared to $35.6
million for the year ended December 31, 1998, an increase of approximately
$11.4 million, or 32.0%. Such increase was due to the natural gas marketing
activities of RNG, along with increased production from the Company's
producing properties. The increase in production from the Company's
producing properties from 1998 to 1999 was 40.7%. Well operations and
pipeline income for the year ended December 31, 1999 was $5.3 million
compared to $4.6 million for the year ended December 31, 1998, an increase
of approximately $700,000 or 15.2%. Such increase resulted from an increase
in the number of wells operated by the Company. Other income remained
constant at $2.4 million for the years ended December 31, 1999 and 1998.
However for the year ended December 31, 1999 a gain on the sale of oil and
gas property offset the decrease in interest earned in 1999 compared to 1998
due to lower average cash balances.

Costs and expenses. Costs and expenses for the year ended December 31,
1999 were $86.7 million compared to $74.3 million for the year ended
December 31, 1998, an increase of approximately $12.4 million, or 16.7%.
Oil and gas well drilling operations costs for the year ended December 31,
1999 were $35.5 million compared to $35.0 million for the year ended
December 31, 1998, an increase of approximately $500,000 or 1.4%. Such
increase resulted from additional expenses due to increased drilling
activity. Oil and gas purchases and production costs for the year ended
December 31, 1999 were $44.2 million compared to $33.6 million for the year
ended December 31, 1998, an increase of approximately $10.6 million, or
31.5%. Such increase was due primarily to natural gas marketing activities
of RNG along with production costs associated with the increased production

-21-

from the Company's producing properties. General and administrative
expenses for the year ended December 31, 1999 were $2.8 million compared to
$2.5 million for the year ended December 31, 1998, an increase of
approximately $300,000. Depreciation, depletion and amortization costs for
the year ended December 31, 1999 were $4.0 million compared to $3.3 million
for the year ended December 31, 1998, an increase of approximately $700,000
or 21.2%. Such increase was due to the increased amount of investment in
oil and gas properties owned by the Company. Interest costs were $182,000
for the year ended December 31, 1999 as the Company utilized its credit
agreement during the third and fourth quarters of 1999.

Net income. Net income for the year ended December 31, 1999 was $7.8
million compared to $6.7 million for the year ended December 31, 1998, an
increase of approximately $1.1 million or 16.4%.

Year Ended December 31, 1998 Compared with December 31, 1997

Revenues. Total revenues for the year ended December 31, 1998 were
$83.0 million compared to $73.9 million for the year ended December 31,
1997, an increase of approximately $9.1 million, or 12.3%. Drilling
revenues for the year ended December 31, 1998 were $40.4 million compared to
$34.4 for the year ended December 31, 1997, an increase of approximately
$6.0 million, or 17.4%. Such increase was due to an increase in drilling
and completion activities, which was a direct result of an increase in
drilling funds from the Company's public drilling programs. Oil and gas
sales for the year ended December 31, 1998 were $35.6 million compared to
$33.4 million for the year ended December 31, 1997, an increase of
approximately $2.2 million, or 6.6%. Such increase was due primarily to the
natural gas marketing activities of RNG, along with increased production
from the Company's producing properties. This increase in production was
offset in part by lower average sales prices from the Company's producing
properties and decreased natural gas purchased for resale. Well operations
and pipeline income for the year ended December 31, 1998 was $4.6 million
compared to $4.5 million for the year ended December 31, 1997, an increase
of approximately $100,000, or 2.2%. Such increase resulted from an increase
in the number of wells operated by the Company. Other income for the year
ended December 31, 1998 was $2.4 million compared to $1.6 million for the
year ended December 31, 1997, an increase of approximately $800,000 or
50.0%. Such increase was due to management fees earned on higher volumes of
drilling partnerships and interest earned on higher average cash balances.

Costs and expenses. Costs and expenses for the year ended December 31,
1998 were $74.3 million compared to $64.2 million for the year ended
December 31, 1997, an increase of approximately $10.1 million, or 15.7%.
Oil and gas well drilling operations costs for the year ended December 31,
1998 were $35.0 million compared to $28.0 million for the year ended
December 31, 1997, an increase of approximately $7.0 million, or 25.0%. Such
increase resulted from additional expenses due to increased drilling
activity. Oil and gas purchases and production costs for the year ended
December 31, 1998 were $33.6 million compared to $30.9 million for the year
ended December 31, 1997, an increase of approximately $2.7 million, or 8.7%.
Such increase was due primarily to natural gas marketing activities of RNG
along with production costs associated with the increased production from
the Company's producing properties, offset in part by lower volumes of gas
purchased for resale by the Company. General and administrative expenses
for the year ended December 31, 1998 were $2.5 million compared to $2.3
million for the year ended December 31, 1997, an increase of approximately
$200,000. Depreciation, depletion and amortization costs for the year ended
December 31, 1998 were $3.3 million compared to $2.7 million for the year
ended December 31, 1997, an increase of approximately $600,000 or 18.5%.
Such increase was due to the increased amount of investment in oil and gas
properties owned by the Company. Interest costs were eliminated after the
Company extinguished the balance on its bank credit line in November, 1997.




-22-

Net income. Net income for the year ended December 31, 1998 was $6.7
million compared to $7.6 million for the year ended December 31, 1997, a
decrease of approximately $900,000, or 11.8%.

Year 2000 Issue

The Company experienced no known disruptions as a result of the year
date change and intends to continue monitoring its critical systems at
various other date changes during the Year 2000.

The Company expenditures for addressing Year 2000 issues were not
material, nor does the Company expect to incur any significant costs
addressing Year 2000 issues in the future.

Liquidity and Capital Resources

The Company funds its operations through a combination of cash flow
from operations, capital raised through stock offerings and drilling
partnerships, and use of the Company's credit facility. Operational cash
flow is generated by sales of natural gas from the Company's well interests,
well drilling and operating activities for the Company's investor partners,
natural gas gathering and transportation, and natural gas marketing. Cash
payments from Company-sponsored partnerships are used to drill and complete
wells for the partnerships, with operating cash flow accruing to the Company
to the extent payments exceed drilling costs. The Company utilizes its
revolving credit arrangement to meet the cash flow requirements of its
operating and investment activities.

Sales volumes of natural gas have continued to increase while natural
gas prices fluctuate monthly. The Company's natural gas sales prices are
subject to increase and decrease based on various market-sensitive indices.
A major factor in the variability of these indices is the seasonal variation
of demand for the natural gas, which typically peaks during the winter
months. The volumes of natural gas sales are expected to continue to
increase as a result of continued drilling activities and additional
investment by the Company in oil and gas properties. The Company utilizes
commodity-based derivative instruments (natural gas futures and option
contracts traded on the NYMEX) as hedges to manage a portion of its exposure
to this price volatility. The futures contracts hedge committed and
anticipated natural gas purchases and sales, generally forecasted to occur
within a three to twelve-month period.

The Company has a bank credit agreement with First National Bank of
Chicago, which provides a borrowing base of $20.0 million, subject to
adequate oil and natural gas reserves. As of December 31, 1999, the balance
outstanding on the line of credit is $9.3 million. Interest accrues at
prime, with LIBOR (London Interbank Market Rate) alternatives available at
the discretion of the Company. No principal payments are required until the
credit agreement expires on December 31, 2002.

The Company closed four public drilling partnerships during 1999. The
total amount received during 1999 was $36.1 million compared to $40.9
million for 1998. The Company closed its fourth program of 1999 on December
31, 1999 in the amount of $18.7 million and will drill the wells during the
first quarter 2000. The Company generally invests, as its equity
contribution to each drilling partnership, an additional sum approximating
20% of the aggregate subscriptions received for that particular drilling
partnership. As a result, the Company is subject to substantial cash
commitments at the closing of each drilling partnership. The funds received
from these programs are restricted to use in future drilling operations. No
assurance can be made that the Company will continue to receive this level
of funding from these or future programs.




-23-

On January 29, 1999, the Company offered to purchase from Investors
their units of investment in the Company's Drilling Programs formed prior to
1996. The Company purhased approximately $1.8 million of producing oil and
gas properties in conjunction with this offer, which expired on March 31,
1999. The Company utilized capital received from its 1997 public stock
offering to fund this purchase.

On December 15, 1999, the Company purchased all of the working interest
in 53 producing wells in the D-J Basin of Colorado. The Company estimates
that the purchase includes proved developed reserves of approximately 3.6
Bcf of natural gas and 370,000 barrels of oil or approximately 5.8 Bcf
equivalent (Bcfe), along with another 3.0 Bcfe of net development drilling
locations. The total acquisition cost for the wells and locations was $5.2
million. The Company utilized part of its existing line of credit to fund
the transaction. The effective date of the transaction was December 1,
1999.

The Company continues to pursue capital investment opportunities in
producing natural gas properties as well as its plan to participate in its
sponsored natural gas drilling partnerships, while pursuing opportunities
for operating improvements and costs efficiencies. Management believes that
the Company has adequate capital to meet its operating requirements.

New Accounting Standards

Statement of Accounting Standards No. 133, Accounting for Derivative
Instruments and Hedging Activities (SFAS No. 133), was issued by the
Financial Accounting Standards Board in June, 1998. SFAS No. 133
standardized the accounting for derivative instruments, including certain
derivative instruments embedded in other contracts. SFAS No. 133 is
effective for years beginning after June 15, 2000; however, early adoption
is permitted. On adoption, the provisions of SFAS No. 133 must be applied
prospectively. At the present time, the Company cannot determine the impact
that SFAS No. 133 will have on its financial statements upon adoption, as
such impact will be based on the extent of derivative instruments, such as
natural gas futures and option contracts, outstanding at the date of
adoption.


Item 7.a. Quantitative and Qualitative Disclosure About Market Risk.

Market-Sensitive Instruments and Risk Management

The Company's primary market risk exposures are interest rate risk and
commodity price risk. These exposures are discussed in detail below:

Interest Rate Risk

The Company's exposure to market risk for changes in interest rates
relates primarily to the Company's interest-bearing cash and cash
equivalents and long-term debt. Interest-bearing cash and cash equivalents
includes money market funds, certificates of deposit and checking and
savings accounts with various banks. The amount of interest-bearing cash
and cash equivalents as of December 31, 1999 is $9,992,700 with an average
interest rate of 3.63 percent. As of December 31, 1999, the Company has
long-term debt of $9,300,000 of which $6,300,000 is at a prime interest rate
of 8.5% and $3,000,000 at a LIBOR interest rate of 7.73%.










-24-

Commodity Price Risk

The Company utilizes commodity-based derivative instruments as hedges
to manage a portion of its exposure to price risk from its natural gas sales
and marketing activities. These instruments consist of NYMEX-traded natural
gas futures contracts and option contracts. These hedging arrangements have
the effect of locking in for specified periods (at predetermined prices or
ranges of prices) the prices the Company will receive for the volume to
which the hedge relates. As a result, while these hedging arrangements are
structured to reduce the Company's exposure to decreases in price associated
with the hedging commodity, they also limit the benefit the Company might
otherwise have received from price increases associated with the hedged
commodity. The Company's policy prohibits the use of natural gas future and
option contracts for speculative purposes. As of December 31, 1999, PDC had
entered into a series of natural gas future contracts and options contracts.
Open future contracts maturing in 2000 are for the purchase of 1,820,000
MMBtu of natural gas with a weighted average price of $2.3725 MBtu resulting
in a total contract amount of $4,317,950, and a fair market value of
$350,500.

PETROLEUM DEVELOPMENT CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Years Ended December 31, 1999, 1998 and 1997

(1) Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts
of Petroleum Development Corporation and its wholly owned
subsidiaries. All material intercompany accounts and transactions
have been eliminated in consolidation. The Company accounts for its
investment in limited partnerships under the proportionate
consolidation method. Under this method, the Company's financial
statements include its prorata share of assets and liabilities and
revenues and expenses, respectively, of the limited partnerships in
which it participates.

The Company is involved in three business segments. The segments are
drilling and development, natural gas sales and well operations. (See
Note 18)

The Company grants credit to purchasers of oil and gas and the owners
of managed properties, substantially all of whom are located in West
Virginia, Tennessee, Pennsylvania, Ohio, Michigan and Colorado.

Cash Equivalents

For purposes of the statement of cash flows, the Company considers all
highly liquid debt instruments with original maturities of three
months or less to be cash equivalents.

Inventories

Inventories of well equipment, parts and supplies are valued at the
lower of average cost or market. An inventory of natural gas is
recorded when gas is purchased in excess of deliveries to customers
and is recorded at the lower of cost or market.

Oil and Gas Properties

Exploration and development costs are accounted for by the successful
efforts method.

The Company assesses impairment of capitalized costs of proved oil and
gas properties by comparing net capitalized costs to undiscounted
future net cash flows on a field-by-field basis using expected
prices. Prices utilized in each year's calculation for measurement
purposes and expected costs are held constant throughout the
estimated life of the properties. If net capitalized costs exceed
undiscounted future net cash flow, the measurement of impairment is
based on estimated fair value which would consider future discounted
cash flows.

Property acquisition costs are capitalized when incurred. Geological
and geophysical costs and delay rentals are expensed as incurred.
The costs of drilling exploratory wells are capitalized pending
determination of whether the wells have discovered economically
producible reserves. If reserves are not discovered, such costs are
expensed as dry holes. Development costs, including equipment and
intangible drilling costs related to both producing wells and
developmental dry holes, are capitalized.

Unproved properties are assessed on a property-by-property basis and
properties considered to be impaired are charged to expense when such
impairment is deemed to have occurred.

(Continued)
F-8
PETROLEUM DEVELOPMENT CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Costs of proved properties, including leasehold acquisition,
exploration and development costs and equipment, are depreciated or
depleted by the unit-of-production method based on estimated proved
developed oil and gas reserves.

Upon sale or retirement of complete units of depreciable or depletable
property, the net cost thereof, less proceeds or salvage value, is
credited or charged to income. Upon retirement of a partial unit of
property, the cost thereof is charged to accumulated depreciation and
depletion.

Based on the Company's experience, management believes site restor-
ation, dismantlement and abandonment costs net of salvage to be
immaterial in relation to operating costs. These costs are being
expensed when incurred.

Transportation Equipment, Pipelines and Other Equipment

Transportation equipment, pipelines and other equipment are carried at
cost. Depreciation is provided principally on the straight-line
method over useful lives of 3 to 17 years. These assets are reviewed
for impairment whenever events or changes in circumstances indicate
that the carrying amount of the assets may not be recoverable. An
impairment loss based on estimated fair value is recorded when the
review indicates that the related expected future net cash flow
(undiscounted and without interest charges) is less than the carrying
amount of the asset.

Maintenance and repairs are charged to expense as incurred. Major
renewals and betterments are capitalized. Upon the sale or other
disposition of assets, the cost and related accumulated depreciation,
depletion and amortization are removed from the accounts, the
proceeds applied thereto and any resulting gain or loss is reflected
in income.

Buildings

Buildings are carried at cost and depreciated on the straight-line
method over estimated useful lives of 30 years.

Advances for Future Drilling Contracts

Represents funds received from Partnerships and other joint ventures
for drilling activities which have not been completed and accordingly
have not yet been recognized as income in accordance with the
Company's income recognition policies.

Retirement Plans

The Company has a 401-K contributory retirement plan (401-K Plan)
covering full-time employees. The Company provides a discretionary
matching of employee contributions to the plan.

The Company also has a profit sharing plan covering full-time
employees. The Company's contributions to this plan are
discretionary.

The Company has a deferred compensation arrangement covering executive
officers of the Company as a supplemental retirement benefit.

F-9

PETROLEUM DEVELOPMENT CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

The Company has established split-dollar life insurance arrangements
with certain executive officers. Under these arrangements, advances
are made to these officers equal to the premiums due. The advances
are collateralized by the cash surrender value of the policies. The
Company records as other assets its share of the cash surrender value
of the policies.

Revenue Recognition

Oil and gas wells are drilled primarily on a contract basis. The
Company follows the percentage-of-completion method of income
recognition for drilling operations in progress.

Well operations income consists of operation charges for well upkeep,
maintenance and operating lease income on tangible well equipment.

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax
consequences attributable to differences between the financial
statement carrying amounts of existing assets and liabilities and
their respective tax bases. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income
in the years in which those temporary differences are expected to be
recovered or settled. The effect on deferred tax assets and
liabilities of a change in tax rates is recognized in income in the
period that includes the enactment date.

Derivatives

Gains and losses related to qualifying hedges of firm commitments or
anticipated transactions through the use of natural gas futures and
option contracts are deferred and recognized in income or as
adjustments of carrying amounts when the underlying hedged
transaction occurs. In order for futures contracts to qualify as a
hedge, there must be sufficient correlation to the underlying hedged
transaction. The change in the fair value of derivative instruments
which do not qualify for hedging are recognized into income
currently.

Stock Compensation

The Company has adopted SFAS No. 123, "Accounting for Stock-Based
Compensation," which permits entities to recognize as expense over
the vesting period the fair value of all stock-based awards on the
date of grant. Alternatively, SFAS 123 allows entities to continue
to measure compensation cost for stock-based awards using the
intrinsic value based method of accounting prescribed by APB Opinion
No. 25, "Accounting for Stock Issued to Employees," and to provide
pro forma net income and pro forma earnings per share disclosures as
if the fair value based method defined in SFAS 123 had been applied.
The Company has elected to continue to apply the provisions of APB 25
and provide the pro forma disclosure provisions of SFAS 123. See
note 5 to the financial statements.

Use of Estimates

Management of the Company has made a number of estimates and
assumptions relating to the reporting of assets and liabilities and
revenues and expenses and the disclosure of contingent assets and
liabilities to prepare these financial statements in conformity with
generally accepted accounting principles. Actual results could
differ from those estimates. Estimates which are particularly
significant to the consolidated financial statements include
estimates of oil and gas reserves and future cash flows from oil and
gas properties.

Reclassifications

Certain items and amounts reported in the 1998 and 1997 consolidated
finnancial statements have been reclassified to conform to the current
year's reporting format.

Fair Value of Financial Instruments

The carrying values and fair values of the Company's receivables,
payables and debt obligations are estimated to be substantially the
same as of December 31, 1999, 1998 and 1997.

New Accounting Standards

Statement of Accounting Standards No. 133, Accounting for Derivative
Instruments and Hedging Activities (SFAS No. 133), was issued by the
Financial Accounting Standards Board in June, 1998. SFAS No. 133
standardized the accounting for derivative instruments, including
certain derivative instruments embedded in other contracts. SFAS No.
133 is effective for years beginning after June 15, 2000; however,
early adoption is permitted. On adoption, the provisions of SFAS No.
133 must be applied prospectively. At the present time, the Company
cannot determine the impact that SFAS No. 133 will have on its
financial statements upon adoption, as such impact will be based on the
extent of derivative instruments, such as natural gas futures and
option contracts, outstanding at the date of adoption.



(2) Notes and Accounts Receivable

Included in other assets are noncurrent notes and accounts receivable
as of December 31, 1999 and 1998, in the amounts of $494,000 and
$617,900 net of the allowance for doubtful accounts of $216,900 and
$129,800, respectively.

The allowance for doubtful current accounts receivable as of December
31, 1999 and 1998 was $221,500 and $144,800, respectively.

(3) Long-Term Debt


On June 22, 1999 the Company executed an Amendment to its Credit
Agreement with First National Bank of Chicago. The amendment
provides a $20.0 million borrowing base, subject to adequate oil and
gas reserves. The Company has activated $10.0 million of such
borrowing base, and has at its discretion the ability to activate the
additional $10.0 million. The Company is required to pay a
commitment fee of 1/4 percent on the unused portion of the activated
credit facility. Interest accrues at prime, with LIBOR (London
Interbank Market Rate) alternatives available at the discretion of
the Company. No principal payments are required until the credit
agreement expires on December 31, 2002.

As of December 31, 1999 the outstanding balance was $9,300,000 of which
$6,300,000 is at a prime rate of 8.5% and $3,000,000 at a LIBOR rate
of 7.73%. At December 31, 1998 there was no balance outstanding. Any
amounts outstanding under the credit agreement are secured by
substantially all properties of the Company. The credit agreement
requires, among other things, the existence of satisfactory levels of
natural gas reserves, maintenance of certain working capital and
tangible net worth ratios along with a restriction on the payment of
dividends.

PETROLEUM DEVELOPMENT CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

The net changes in the total valuation allowance were decreases of
$375,000, $473,200 and $782,300 for the years ended December 31, 1999,
1998 and 1997, respectively.

At December 31, 1999, the Company has alternative minimum tax credit
carryforwards (Section 29) of approximately $1,982,300 which are
available to reduce future federal regular income taxes over an
indefinite period.

(5) Common Stock

Options

Options amounting to 145,000, 20,000 and 500,000 shares were granted
during 1999, 1998 and 1997, respectively, to certain employees and
directors under the Company's Stock Option Plans. These options were
granted with an exercise price equal to market value as of the date of
grant and vest over a six month period for the 1999 grant and a two
year period for the 1998 and 1997 grants. The outstanding options
expire from 2000 to 2009.

The estimated fair value of the options granted during 1999, 1998 and
1997 was $2.44, $3.92 and $3.30 per option, respectively. The fair
value was estimated using the Black-Scholes option pricing model with
the following assumptions for the 1999, 1998 and 1997 grant,
respectively: risk-free interest rate of 5.1%, 5.9% and 6.3%, expected
dividend yield of 0%, expected volatility of 61.3%, 58.0% and 57.4% and
expected life of 7 years.

PETROLEUM DEVELOPMENT CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

The Company accounts for its stock-based compensation plans under APB
25. For stock options granted, the option price was not less than the
market value of shares on the grant date, therefore, no compensation
cost has been recognized. Had compensation cost been determined under
the provisions of SFAS 123, the Company's net income and earnings per
share would have been the following on a pro forma basis:



1999 1998

Net income $7,824,300 $7,336,200 $6,658,000 $5,918,800

Diluted earnings
per share $ .48 $ .45 $ .41 $ .37

Stock Redemption Agreement

The Company has stock redemption agreements with three officers of the
Company. The agreements require the Company to maintain life insurance
on each executive in the amount of $1,000,000. The agreements provide
that the Company shall utilize the proceeds from such insurance to
purchase from such executives' estates or heirs, at their option,
shares of the Company's stock. The purchase price for the outstanding
common stock is to be based upon the average closing asked price for
the Company's stock as quoted by NASDAQ during a specified period. The
Company is not required to purchase any shares in excess of the amount
provided for by such insurance.

Stock Offerings

In September 1997, the Company completed a private offering of Common
Stock pursuant to which it issued and sold 500,000 shares at a price of
$4.00 per share and issued warrants for 125,000 shares of Common Stock
exercisable during a two-year period ending September 15, 1999 at an
exercise price of $6.00 per share, resulting in proceeds to the Company
of $2.0 million. The warrants were not exercised and expired on
September 15, 1999. No registration rights were granted in connection
with the securities issued in this offering.

In November 1997, the Company completed a public offering of 4,077,500
shares of its Common Stock at a price of $6.25 per share. Net proceeds
to the Company of approximately $23 million from the sale of common
stock was designated to fund development drilling on new and existing
properties, potential acquisition of producing properties and general
corporate purposes, including working capital and possible acquisitions
of complementary businesses.

(9) Commitments and Contingencies

The nature of the independent oil and gas industry involves a dependence
on outside investor drilling capital and involves a concentration of
gas sales to a few customers. The Company sells natural gas to various
public utilities and industrial customers. No customer accounted for
more than 10.0% of total revenues in 1999 or 1998. One customer, Hope
Gas, Inc., a regulated public utility accounted for 12.0% of total
revenue in 1997.

Substantially all of the Company's drilling programs contain a repurchase
provision where Investors may tender their partnership units for
repurchase at any time beginning with the third anniversary of the
first cash distribution. The provision provides that the Company is
obligated to purchase an aggregate of 10% of the initial subscriptions
per calendar year (at a minimum price of four times the most recent 12
months' cash distributions), only if such units are tendered, subject
to the Company's financial ability to do so. The maximum annual 10%
repurchase obligation, if tendered by the investors, is currently
approximately $759,000. The Company has adequate capital to meet this
obligation.

The Company is not party to any legal action that would materially affect
the Company's results of operations or financial condition.

(10) Supplemental Disclosure of Cash Flows

The Company paid $124,200, $0, and $380,000 for interest in 1999, 1998
and 1997, respectively. The Company paid income taxes in 1999, 1998
and 1997 in the amounts of $1,327,800, $2,349,100 and $1,932,500,
respectively.

(11) Acquisitions

On February 19, 1998, the Company offered to purchase from Investors
their units of investment in the Company's Drilling Programs formed
prior to 1993. The Company purchased approximately $2.3 million of
producing oil and gas properties in conjunction with this offer, which
expired on March 31, 1998. The Company utilized capital received from
its Public Stock Offering to fund this purchase.

On June 12, 1998 the Company purchased for $3.1 million a majority
interest in the assets of Pemco Gas, Inc., a Pennsylvania producing
company. The assets include 122 natural gas wells, 2,700 undeveloped
acres, gathering systems, natural gas compressors and other facilities.
The Company estimates that its interest includes 4.7 Bcf of natural gas
reserves. The Company utilized capital received from its Public Stock
Offering to fund this purchase.

On November 16, 1998, the Company purchased all of the working interest
in a 13 well Antrim Shale production unit and adjacent development
locations in Montmorency County, Michigan. The Company estimates that
the purchase includes approximately 4 Bcf of proved developed producing
reserves and 1.5 Bcf of proved undeveloped reserves, with an
acquisition cost of approximately $2.8 million. The Company utilized
capital received from its Public Stock Offering to fund this purchase.

On January 29, 1999, the Company offered to purchase from Investors their
units of investment in the Company's Drilling Programs formed prior to

(12) Derivatives and Hedging Activities

The company utilizes commodity based derivative instruments as hedges to
manage a portion of its exposure to price volatility stemming from its
integrated natural gas production and marketing activities. These
instruments consist of natural gas futures and option contracts traded
on the New York Mercantile Exchange. The futures and option contracts
hedge committed and anticipated natural gas purchases and sales,
generally forecasted to occur within a 12 month period. The Company
does not hold or issue derivatives for trading or speculative purposes.

As of December 31, 1999 and 1998, the Company had futures contracts for
the purchase of $4,318,000 and $1,120,300 of natural gas, respectively.
While these contracts have nominal carrying value, their fair value,
represented by the estimated amount that would be received upon
termination of the contracts, based on market quotes, was a net value
of $350,500 at December 31, 1999 and $(105,400) at December 31, 1998.

The Company is required to maintain margin deposits with brokers for
outstanding futures contracts. As of December 31, 1999 and 1998, cash
in the amount of $614,300 and $156,200 was on deposit.

(16) Net Proved Oil and Gas Reserves (Unaudited)

The proved reserves of oil and gas of the Company have been estimated
by an independent petroleum engineer, Wright & Company, Inc. at
December 31, 1999, 1998 and 1997. These reserves have been prepared
in compliance with the Securities and Exchange Commission rules based
on year end prices. An analysis of the change in estimated
quantities of oil and gas reserves, all of which are located within
the United States, is shown below:

(17) Standardized Measure of Discounted Future Net Cash Flows and Changes
Therein Relating to Proved Oil and Gas Reserves (Unaudited)

Summarized in the following table is information for the Company with
respect to the standardized measure of discounted future net cash
flows relating to proved oil and gas reserves. Future cash inflows
are computed by applying year-end prices of oil and gas relating to
the Company's proved reserves to the year-end quantities of those
reserves. Future production, development, site restoration and
abandonment costs are derived based on current costs assuming
continuation of existing economic conditions. Future income tax
expenses are computed by applying the statutory rate in effect at the
end of each year to the future pretax net cash flows, less the tax
basis of the properties and gives effect to permanent differences,
tax credits and allowances related to the properties.

It is necessary to emphasize that the data presented should not be
viewed as representing the expected cash flow from, or current value
of, existing proved reserves since the computations are based on a
large number of estimates and arbitrary assumptions. Reserve
quantities cannot be measured with precision and their estimation
requires many judgmental determinations and frequent revisions. The
required projection of production and related expenditures over time
requires further estimates with respect to pipeline availability,
rates of demand and governmental control. Actual future prices and
costs are likely to be substantially different from the current
prices and costs utilized in the computation of reported amounts.
Any analysis or evaluation of the reported amounts should give
specific recognition to the computational methods utilized and the
limitations inherent therein.
