     This summary highlights selected information contained elsewhere in this
prospectus. You should read the entire prospectus carefully before making an
investment decision.


Overview

     PYR Energy Corporation (referred to as "PYR," the "Company," "we," "us" and
"our") is an independent oil and gas exploration and production company, engaged
in the exploration, development and acquisition of crude oil and natural gas
reserves. Our current focus is on the Rocky Mountain, Texas and Gulf Coast
regions. During the fiscal years ended August 31, 2005 and 2004, we focused our
exploration efforts on the drilling phase of our high potential exploration
projects in the Rocky Mountain and Gulf Coast regions.

     The Company was incorporated in March 1996 in the state of Delaware under
the name Mar Ventures Inc. Effective as of August 6, 1997, the Company purchased
all the ownership interests of PYR Energy, LLC, an oil and gas exploration
company. On November 12, 1997, the name of the Company was changed to PYR Energy
Corporation. Effective July 2, 2001, the Company was re-incorporated in Maryland
through the merger of the Company into a wholly owned subsidiary, PYR Energy
Corporation, a Maryland corporation. On February 18, 2004, PYR Cumberland LLC,
PYR Mallard LLC, and PYR Pintail LLC were formed as wholly owned subsidiaries of
PYR Energy Corporation. The purpose of these entities is to own and develop
certain assets related to designated individual exploration projects.

                                       1



                                  RISK FACTORS

You should carefully consider each of the following risk factors and all of the
other information provided in this prospectus before purchasing our common
stock. The risks described below are those we currently believe may materially
affect us. An investment in our common stock involves a high degree of risk, and
should be considered only by persons who can afford the loss of their entire
investment.

Risks Related to Our Business

     We have a limited operating history in the oil and gas business. Our
operations to date have consisted solely of evaluating geological and
geophysical information, acquiring acreage positions, generating exploration
prospects, and drilling a limited number of wells. We currently have nine
full-time employees. Our future financial results depend primarily on (1) our
ability to discover commercial quantities of oil and gas; (2) the market price
for oil and gas; (3) our ability to continue to generate potential exploration
prospects; and (4) our ability to fully implement our exploration and
development program. We cannot predict that our future operations will be
profitable. In addition, our operating results may vary significantly during any
financial period. These variations may be caused by significant periods of time
between discovery and development of oil or gas reserves, if any, in commercial
quantities.

     Our cash resources are not unlimited. We need to increase our sources of
revenue and/or funding in order to sustain operations for the long run. There is
no assurance that this will occur.

     We may not discover commercially productive reserves. Our future success
depends on our ability to economically locate oil and gas reserves in commercial
quantities. Except to the extent that we acquire properties containing proved
reserves or that we conduct successful exploration and development activities,
or both, our proved reserves, if any, will decline as reserves are produced. Our
ability to locate reserves is dependent upon a number of factors, including our
participation in multiple exploration projects and our technological capability
to locate oil and gas in commercial quantities. We cannot predict that we will
have the opportunity to participate in projects that economically produce
commercial quantities of oil and gas in amounts necessary to meet our business
plan or that the projects in which we elect to participate will be successful.
There can be no assurance that our planned projects will result in significant
reserves or that we will have future success in drilling productive wells at
economical reserve replacement costs.

     Exploratory drilling is an uncertain process with many risks. Exploratory
drilling involves numerous risks, including the risk that we will not find any
commercially productive oil or gas reservoirs. The cost of drilling, completing
and operating wells is often uncertain, and a number of factors can delay or
prevent drilling operations, including:


     o    unexpected drilling conditions,
 
     o    pressure or irregularities in formations,
 
     o    equipment failures or accidents,
 
     o    adverse weather conditions,
 
     o    compliance with governmental requirements,
 
     o    shortages or delays in the availability of drilling rigs and the
          delivery of equipment, and
 
     o    shortages of trained oilfield service personnel.

                                       2




     Our future drilling activities may not be successful, nor can we be sure
that our overall drilling success rate or our drilling success rate for
activities within a particular area will not decline. Unsuccessful drilling
activities could have a material adverse effect on our results of operations and
financial condition. Also, we may not be able to obtain any options or lease
rights in potential drilling locations that we identify. Although we have
identified a number of potential exploration projects, we cannot be sure that we
will ever drill them or that we will produce oil or gas from them or any other
potential exploration projects.

     Our exploration and development activities are subject to reservoir and
operational risks. Even when oil and gas is found in what is believed to be
commercial quantities, reservoir risks, which may be heightened in new
discoveries, may lead to increased costs and decreased production. These risks
include the inability to sustain deliverability at commercially productive
levels as a result of decreased reservoir pressures, large amounts of water, or
other factors that might be encountered. As a result of these types of risks,
most lenders will not loan funds secured by reserves from newly discovered
reservoirs, which would have a negative impact on our future liquidity.
Operational risks include hazards such as fires, explosions, craterings,
blowouts (such as the blowout experienced at our initial exploratory well),
uncontrollable flows of oil, gas or well fluids, pollution, releases of toxic
gas and encountering formations with abnormal pressures. In addition, we may be
liable for environmental damage caused by previous owners of property we own or
lease. As a result, we may face substantial liabilities to third parties or
governmental entities, which could reduce or eliminate funds available for
exploration, development or acquisitions or cause us to incur substantial
losses.

     We expect to maintain insurance against some, but not all, of the risks
associated with drilling and production in amounts that we believe to be
reasonable in accordance with customary industry practices. The occurrence of a
significant event, however, that is not fully insured could have a material
adverse effect on our financial condition and results of operations.

     Our operations require large amounts of capital. Our current development
plans will require us to make large capital expenditures for the exploration and
development of our oil and gas projects. Under our current capital expenditure
budget, we expect to spend between $7.5 and $10.0 million on exploration and
development activities during our fiscal year ending August 31, 2006. Also, we
must secure substantial capital to explore and develop our other potential
projects. Historically, we have funded our capital expenditures through the
issuance of equity. Volatility in the price of our common stock, which may be
significantly influenced by our drilling and production activity, may impede our
ability to raise money quickly, if at all, through the issuance of equity at
acceptable prices. Future cash flows and the availability of financing will be
subject to a number of variables, such as:

     o    our success in locating and producing reserves in other projects,
 
     o    the level of production from existing wells, and
 
     o    prices of oil and gas.

     Issuing equity securities to satisfy our financing requirements could cause
substantial dilution to our existing stockholders. Debt financing, if obtained,
could lead to:

     o    a substantial portion of our operating cash flow being dedicated to
          the payment of principal and interest,

                                       3


 
     o    our being more vulnerable to competitive pressures and economic
          downturns, and
 
     o    restrictions on our operations.


     If our revenues were to decrease due to lower oil and gas prices, decreased
production or other reasons, and if we could not obtain capital through a credit
facility or otherwise, our ability to execute our development plans, obtain and
replace reserves, or maintain production levels could be greatly limited.

     We depend heavily on exploration success and subsequent success in
developing our exploration projects. Our future growth plans rely heavily on
discovering reserves and initiating production in the Texas, Gulf Coast and in
the Rocky Mountains. Our development plan includes the need to discover reserves
and establish commercial production through exploratory drilling and development
of our existing properties. We cannot be sure, though, that our planned projects
will lead to significant reserves that can be economically extracted or that we
will be able to drill productive wells at anticipated finding and development
costs. If we are able to record reserves, our reserves will decline as they are
depleted, except to the extent that we conduct successful exploration or
development activities or acquire other properties containing proved reserves.

     We depend on industry alliances. We attempt to limit financial exposure on
a project-by-project basis by forming industry alliances where our technical
expertise can be complemented with the financial resources and operating
expertise of more established companies. Although entering into these alliances
limits our financial exposure, it also limits our potential revenue from
successful projects. Industry alliances also have the potential to expose us to
uncertainty if our industry partners are acquired or have priorities in areas
other than our projects. Despite these risks, we believe that if we are not able
to form industry alliances, our ability to fully implement our business plan
could be limited, which could have a material adverse effect on our business.

     Our non-operator status limits our control over our oil and gas projects.
We focus primarily on creating exploration opportunities and forming industry
alliances to develop those opportunities. As a result, we have only a limited
ability to exercise control over a significant portion of a project's operations
or the associated costs of those operations. The success of a project is
dependent upon a number of factors that are outside our areas of expertise and
control. These factors include:

     o    the availability of leases with favorable terms and the availability
          of required permitting for projects,
 
     o    the availability of future capital resources to us and the other
          participants to be used for purchasing leases and drilling wells,
 
     o    the approval of other participants for the purchasing of leases and
          the drilling of wells on the projects, and
 
     o    the economic conditions at the time of drilling, including the
          prevailing and anticipated prices for oil and gas.

     Our reliance on other project participants and our limited ability to
directly control project costs could have a material adverse effect on our
expected rates of return.

     Oil and gas prices are volatile and an extended decline in prices could
hurt our business prospects. Our future profitability and rate of growth and the
anticipated carrying value of our oil and gas properties will depend heavily on
then prevailing market prices for oil and gas. We expect the markets for oil and

                                       4




gas to continue to be volatile. If we are successful in continuing to establish
production, any substantial or extended decline in the price of oil or gas
could:


     o    have a material adverse effect on our results of operations,
 
     o    limit our ability to attract capital,
 
     o    make the formations we are targeting significantly less attractive
          economically,
 
     o    reduce our cash flow and borrowing capacity, and
 
     o    reduce the value and the amount of any future reserves.

     Various factors beyond our control will affect prices of oil and gas,
including:


     o    worldwide and domestic supplies of oil and gas,
 
     o    the ability of the members of the Organization of Petroleum Exporting
          Countries to agree to and maintain oil price and production controls,
 
   o   political instability or armed conflict in oil or gas producing regions,
 
     o    the price and level of foreign imports,
 
     o    worldwide economic conditions,
 
     o    marketability of production,

     o    the level of consumer demand,
 
     o    the price, availability and acceptance of alternative fuels,
 
     o    the availability of processing and pipeline capacity,
 
     o    weather conditions, and
 
     o    actions of federal, state, local and foreign authorities.

     These external factors and the volatile nature of the energy markets make
it difficult to estimate future prices of oil and gas. In addition, sales of oil
and gas are seasonal in nature, leading to substantial differences in cash flow
at various times throughout the year.

     Accounting rules may require write-downs. Under full cost accounting rules,
capitalized costs of proved oil and gas properties may not exceed the present
value of estimated future net revenues from proved reserves, discounted at 10%.
Application of the ceiling test generally requires pricing future revenue at the
unescalated prices in effect as of the end of each fiscal quarter and requires a
write-down for accounting purposes if the ceiling is exceeded. If a write-down

                                       5




is required, it would result in a charge to earnings, but would not impact cash
flow from operating activities. Once incurred, a write-down of oil and gas
properties is not reversible at a later date.

     We face risks related to title to the leases we enter into that may result
in additional costs and affect our operating results. It is customary in the oil
and gas industry to acquire a leasehold interest in a property based upon a
preliminary title investigation. In many instances, our partners have acquired
rights to the prospective acreage and we have a contractual right to have our
interests in that acreage assigned to us. In some cases, we are in the process
of having those interests so assigned. If the title to the leases acquired is
defective, or title to the leases one of our partners acquires for our benefit
is defective, we could lose the money already spent on acquisition and
development, or incur substantial costs to cure the title defect, including any
necessary litigation. If a title defect cannot be cured or if one of our
partners does not assign to us our interest in a lease acquired for our benefit,
we will not have the right to participate in the development of or production
from the leased properties. In addition, it is possible that the terms of our
oil and gas leases may be interpreted differently depending on the state in
which the property is located. For instance, royalty calculations can be
substantially different from state to state, depending on each state's
interpretation of lease language concerning the costs of production. We cannot
guarantee that there will not be litigation concerning the proper interpretation
of the terms of our leases. Adverse decisions in any litigation of this kind
could result in material costs or the loss of one or more leases.

     Limitations on the Effectiveness of Controls. Our management, including our
Chief Executive Officer and Chief Financial Officer, does not expect that our
disclosure controls or our internal controls will prevent all possible error or
fraud. A control system, no matter how well conceived and operated, can provide
only reasonable, not absolute, assurance that the objectives of the control
system are met. Further the design of a control system must reflect the fact
that there are resource constraints, and the benefits of controls must be
considered relative to their costs. Because of the inherent limitations in all
control systems, no evaluation of controls can provide absolute assurance that
all control issues and instances of fraud, if any, within our company have been
detected. These inherent limitations include the realities that judgments in
decision making can be faulty, and that breakdowns can occur because of simple
error or mistake. Additionally, controls can be circumvented by the individual
acts of some persons, by collusion of two or more people, or by management
override of the control. The design of any system of controls also is based in
part upon certain assumptions about the likelihood of future events, and there
can be no assurance that any design will succeed in achieving its stated goals
under all potential future conditions; over time, controls may become inadequate
because of changes in conditions, or the degree of compliance with the policies
or procedures may deteriorate. Because of the inherent limitations in a
cost-effective control system, misstatements due to error or fraud may occur and
not be detected.

     Our industry is highly competitive and many of our competitors have more
resources than we do. We compete in oil and gas exploration with a number of
other companies. Many of these competitors have financial and technological
resources vastly exceeding those available to us. We cannot be sure that we will
be successful in acquiring and developing profitable properties in the face of
this competition. In addition, from time to time, there may be competition for,
and shortage of, exploration, drilling and production equipment. These shortages
could lead to an increase in costs and delays in operations that could have a
material adverse effect on our business and our ability to develop our
properties. Problems of this nature also could prevent us from producing any oil
and gas we discover at the rate we desire to do so.

     Technological changes could put us at a competitive disadvantage. The oil
and gas industry is characterized by rapid and significant technological
advancements and introductions of new products and services using new
technologies. As new technologies develop, we may be placed at a competitive
disadvantage, and competitive pressures may force us to implement those new
technologies at a substantial cost. If other oil and gas exploration and
development companies implement new technologies before we do, those companies
may be able to provide enhanced capabilities and superior quality compared with

                                       6




what we are able to provide. We may not be able to respond to these competitive
pressures and implement new technologies on a timely basis or at an acceptable
cost. If we are unable to utilize the most advanced commercially available
technologies, our business could be materially and adversely affected.

     Our industry is heavily regulated. Federal, state and local authorities
extensively regulate the oil and gas industry. Legislation and regulations
affecting the industry are under constant review for amendment or expansion,
raising the possibility of changes that may affect, among other things, the
pricing or marketing of oil and gas production. State and local authorities
regulate various aspects of oil and gas drilling and production activities,
including the drilling of wells (through permit and bonding requirements), the
spacing of wells, the unitization or pooling of oil and gas properties,
environmental matters, safety standards, the sharing of markets, production
limitations, plugging and abandonment, and restoration. The overall regulatory
burden on the industry increases the cost of doing business, which, in turn,
decreases profitability.

     Our operations must comply with complex environmental regulations. Our
operations are subject to complex and constantly changing environmental laws and
regulations adopted by federal, state and local governmental authorities. New
laws or regulations, or changes to current requirements, could have a material
adverse effect on our business. We will continue to be subject to uncertainty
associated with new regulatory interpretations and inconsistent interpretations
between state and federal agencies. We could face significant liabilities to the
government and third parties for discharges of oil, natural gas, produced water
or other pollutants into the air, soil or water, and we could have to spend
substantial amounts on investigations, litigation and remediation. We cannot be
sure that existing environmental laws or regulations, as currently interpreted
or enforced, or as they may be interpreted, enforced or altered in the future,
will not have a material adverse effect on our results of operations and
financial condition.

     Our business depends on transportation facilities owned by others. The
marketability of our anticipated gas production depends in part on the
availability, proximity and capacity of pipeline systems owned or operated by
third parties. Federal and state regulation of oil and gas production and
transportation, tax and energy policies, changes in supply and demand and
general economic conditions could adversely affect our ability to produce,
gather and transport oil and natural gas.

     Attempts to grow our business could have an adverse effect. Because of our
small size, we desire to grow rapidly in order to achieve certain economies of
scale. Although there is no assurance that this rapid growth will occur, to the
extent that it does occur, it will place a significant strain on our financial,
technical, operational and administrative resources. As we increase our services
and enlarge the number of projects we are evaluating or in which we are
participating, there will be additional demands on our financial, technical and
administrative resources. The failure to continue to upgrade our technical,
administrative, operating and financial control systems or the occurrence of
unexpected expansion difficulties, including the recruitment and retention of
geoscientists and engineers, could have a material adverse effect on our
business, financial condition and results of operations.

     We may not be able to retain our listing on the American Stock Exchange.
The American Stock Exchange has certain listing requirements in order for a
company to continue to have its securities traded on this exchange. A company
may risk delisting if its common stock trades at a low price per share for a
substantial period of time. Should our stock trade at a low share price for a
substantial period of time, or our net tangible equity be below certain levels,
we may not be able to retain our listing.

     We depend on key personnel. We are highly dependent on the services of D.
Scott Singdahlsen, our President and Chief Executive Officer, and our other
geological and geophysical staff members. The loss of the services of any of
these persons could have a material negative impact on our business. We do not
have an employment contract with Mr. Singdahlsen or any other employee.

                                       7




Risks Related to this Prospectus and Our Common Stock

     Sales of a substantial number of shares in the Offering may result in
significant downward pressure on the price of our common stock and could affect
the ability of our stockholders to realize the current trading price of our
common stock. This registration statement covers the resale of 6,327,250 shares
of common stock that were previously restricted. As a result, the number of
shares of our common stock eligible to be immediately sold in the market will
increase significantly upon the effectiveness of this registration statement. If
the Selling Stockholders sell significant amounts of our stock, our stock price
could drop. Even a perception by the market that the Selling Stockholders will
sell in large amounts after the registration statement is effective could place
significant downward pressure on our stock price.

     Our board of directors can cause us to issue preferred stock with rights
that are preferential to, and could cause a decrease in the value of, our common


stock. Our board of directors may issue up to one million shares of preferred
stock without action by our stockholders. Rights or preferences could include,
among other things:

     o    The establishment of dividends which must be paid prior to declaring
          or paying dividends or other distributions to our common stockholders;
     o    Greater or preferential liquidation rights which could negatively
          affect the rights of common stockholders, and
     o    The right to convert the preferred stock at a rate or price which
          would have a dilutive effect on the outstanding shares of common
          stock.


            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

     This prospectus and the materials incorporated herein by reference contain
forward-looking statements, including statements regarding, among other items,
our business and growth strategies, anticipated trends in our business and our
future results of operations, market conditions in the oil and gas industry, our
ability to make and integrate acquisitions, the outcome of litigation, if any,
and the impact of governmental regulation. These forward-looking statements are
based largely on our expectations and are subject to a number of risks and
uncertainties, many of which are beyond our control. Actual results could differ
materially from these forward-looking statements as a result of, among other
things:

     o    failure to obtain, or a decline in, oil or gas production, or a
          decline in oil or gas prices,
 
     o    incorrect estimates of required capital expenditures,
 
     o    increases in the cost of drilling, completion and gas collection or
          other costs of production and operations,
 
     o    an inability to meet growth projections, and
 
     o    other risk factors set forth under "Risk Factors" in this prospectus.
          In addition, the words "believe," "may," "could," "will," "when,"
          "estimate," "continue," "anticipate," "intend," "expect" and similar
          expressions, as they relate to PYR, our business or our management,
          are intended to identify forward-looking statements.


                                 USE OF PROCEEDS

     The Selling Stockholders will be selling all of the shares under this
prospectus in the Offering. The proceeds from the sale of the shares will be
received directly by the Selling Stockholders. We will receive no proceeds from
the sale of the shares offered by Selling Stockholders under this prospectus.


                                 DIVIDEND POLICY

     We have never paid cash dividends and have no plans to do so in the
foreseeable future. Our future dividend policy will be determined by our board
of directors and will depend upon a number of factors, including our financial
condition and performance, our cash needs and expansion plans, income tax

                                       8




consequences, and the restrictions that applicable laws, our current preferred
stock instruments, and our future credit arrangements may then impose.


                              SELLING STOCKHOLDERS

     The shares covered by this prospectus are being offered by the named
Selling Stockholders below. The Selling Stockholders may from time to time offer
and sell pursuant to this prospectus up to an aggregate of 6,327,250 shares of
our common stock.

     All of the individuals and/or entities listed below participated in a
private placement which commenced on or about September 29, 2005, pursuant to
which we sold a total of 6,275,000 shares of common stock at a price per share
of $1.30. In connection with the private placement, we agreed to issue warrants
to purchase a total of 52,250 shares to a entity which assisted us with the
private placement at an exercise price of $1.42 per share and the shares
underlying these warrants are also covered by this prospectus. In addition, we
agreed to pay placement fees of $102,375.

     In connection with the private placement, we agreed to prepare and file at
our expense, within 75 days of the first closing of the offering, a registration
statement with the Securities and Exchange Commission covering the resale of the
shares of common stock sold in the private placement, and the shares of common
stock underlying the warrants issued in connection with the private placement.

The following table sets forth the following, with respect to the Selling
Stockholders:

     o    The number of shares of common stock beneficially owned as of December
          7, 2005 and prior to the offering contemplated hereby,

     o    The number of shares of common stock eligible for resale and to be
          offered by each Selling Stockholder pursuant to this prospectus,

     o    The number of shares owned by each Selling Stockholder after the
          offering contemplated hereby assuming that all shares eligible for
          resale pursuant to this prospectus actually are sold,

     o    The percentage of our outstanding shares of common stock beneficially
          owned by each Selling Stockholder after the offering contemplated
          hereby, and

     o    In notes to the table, any relationships, excluding non-executive
          employee and other non-material relationships, that a Selling
          Stockholder had during the past three years with the registrant or any
          of its predecessors or affiliates.

                              PLAN OF DISTRIBUTION

     The Selling Stockholders are offering up to 6,327,250 shares of common
stock. It is possible that the increase in shares on the market will have a
negative effect on the resale price of our shares and may make it difficult for
purchasers in the Offering to resell the shares at a profit or at all. The
Selling Stockholders and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their shares
on any stock exchange, market or trading facility on which the shares are traded
or in private transactions. These sales may be at fixed or negotiated prices.

     The Selling Stockholders also may sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus. The Selling
Stockholders may engage in short sales against the box, puts and calls and other
transactions in our securities or derivatives of our securities, and may sell or
deliver shares in connection with these trades. The Selling Stockholders may
pledge their shares to their brokers under the margin provisions of customer
agreements. If a Selling Stockholder defaults on a margin loan, the broker may,
from time to time, offer and sell the pledged shares.

     Broker-dealers engaged by the Selling Stockholders may arrange for other
broker-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from either the Selling Stockholders or, if any broker-dealer acts
as agent for the purchaser of shares, from the purchaser, in amounts to be
negotiated. The Selling Stockholders do not expect these commissions and
discounts to exceed what is customary in the types of transactions involved.

                                       11




     The Selling Stockholders and any broker-dealers or agents that are involved
in selling the shares may be deemed to be "underwriters" within the meaning of
the Securities Act in connection with those sales. In that event, any
commissions received by such broker-dealers or agents and any profit on the
resale of the shares purchased by them may be deemed to be underwriting
commissions or discounts under the Securities Act.

     We are required, or have elected, to pay all fees and expenses incident to
the registration of the shares being registered herein. We are not required to
pay commissions and other selling expenses. We have agreed to indemnify certain
of the Selling Stockholders against losses, claims, damages and liabilities,
including liabilities under the Securities Act arising out of or based upon any
untrue or alleged untrue statement of a material fact contained in the
registration statement, any prospectus or any form of prospectus or in any
amendment or supplement thereto or in any preliminary prospectus, or arising out
of or based upon any omission or alleged omission of a material fact necessary
to make the statements therein not misleading.


                                  LEGAL MATTERS

     The validity of the issuance of the shares of common stock offered hereby
and other legal matters in connection herewith have been passed upon for us by
Patton Boggs LLP. Partners of Patton Boggs LLP own an aggregate of 84,000 shares
of the Company's common stock.

                       SECURITIES AND EXCHANGE COMMISSION
                       POSITION ON CERTAIN INDEMNIFICATION

     The General Corporation Law of the State of Maryland (the "Maryland
Code") provides for mandatory indemnification against reasonable expenses
incurred by directors and officers of a corporation in connection with an
action, suit or proceeding brought by reason of their position as a director or
officer if they are successful, on the merits or otherwise, in defense of the
proceeding. The Maryland Code also allows a corporation to indemnify directors
or officers in such proceedings if the director or officer acted in good faith,
in a manner he reasonably believed to be in or not opposed to the best interests
of the corporation, and, in the case of a criminal proceeding, he had no
reasonable cause to believe that his conduct was unlawful.

     The Maryland Code permits a corporation to expand the rights to
indemnification by a provision in its bylaws, by an agreement, by resolution of
stockholders or directors not involved in the proceeding, or otherwise. However,
a corporation may not indemnify a director or officer if the proceeding was one
by or on behalf of the corporation and in the proceeding the director or officer
is adjudged to be liable to the corporation. Our Bylaws provide that we are
required to indemnify our directors and officers to the fullest extent permitted
by law, including those circumstances in which indemnification would otherwise
be discretionary.

                                       12




     In addition to the general indemnification described above, we have
adopted, in our articles of incorporation, a provision under the Maryland Code
that eliminates and limits certain personal liability of directors and officers
for monetary damages for breaches of the fiduciary duty of care.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers or persons controlling the Company
pursuant to the foregoing provisions, we have been informed that, in the opinion
of the SEC, such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.

Item 15.  Indemnification of Directors and Officers.
---------------------------------------------------

     Section 2-418 of the General Corporation Law of the State of Maryland (the
"Maryland Code") provides for mandatory indemnification against reasonable
expenses incurred by directors and officers of a corporation in connection with
an action, suit or proceeding brought by reason of their position as a director
or officer if they are successful, on the merits or otherwise, in defense of the
proceeding. In addition, a corporation may indemnify directors or officers in
such proceedings if the director or officer acted in good faith, in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, in the case of a criminal proceeding, he had no reasonable
cause to believe that his conduct was unlawful.

     The Maryland Code also permits a corporation to expand the rights to
indemnification by a provision in its bylaws, by an agreement, by resolution of
stockholders or directors not involved in the proceeding, or otherwise. However,
a corporation may not indemnify a director or officer if the proceeding was one
by or on behalf of the corporation and in the proceeding the director of officer
is adjudged to be liable to the corporation.

     The Company's Bylaws provide that the Company is required to indemnify its
directors and officers to the fullest extent permitted by law, including those
circumstances in which indemnification would otherwise be discretionary. The
Company also has adopted, in its Articles of Incorporation, a provision under
Section 2-405.2 of the Maryland Code that eliminates and limits certain personal
liability of directors and officers for monetary damages for breaches of the
fiduciary duty of care.

     We also currently have liability insurance for our directors and officers.

Item 17.  Undertakings.
----------------------

     (a)  The undersigned registrant hereby undertakes:

          1.   To file, during any period in which offers or sales are being
               made, a post-effective amendment to this registration statement:

               (i)  to include any prospectus required by Section 10(a)(3) of
                    the Securities Act of 1933;

               (ii) to reflect in the prospectus any facts or events arising
                    after the effective date of the registration statement (or
                    the most recent post-effective amendment thereof) which,
                    individually or in the aggregate, represent a fundamental
                    change in the information set forth in the registration
                    statement. Notwithstanding the foregoing, any increase or
                    decrease in volume of securities offered (if the total
                    dollar value of securities offered would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of prospectus filed with the Commission pursuant
                    to Rule 424(b) if, in the aggregate, the changes in volume
                    and price represent no more than 20% change in the maximum
                    aggregate offering price set forth in the "Calculation of
                    Registration Fee" table in the effective registration
                    statement.

              (iii) to include any material information with respect to the
                    plan of distribution not previously disclosed in the
                    registration statement or any material change to such
                    information in the registration statement;

                                       15



                    provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii)
                    do not apply if the registration statement is on Form S-3,
                    and if the information required to be included in a
                    post-effective amendment by those paragraphs is contained in
                    periodic reports filed by the registrant pursuant to Section
                    13 or Section 15(d) of the Securities Exchange Act of 1934
                    and are incorporated by reference to the registration
                    statement.

               2.   That, for the purpose of determining any liability under the
                    Securities Act, each such post-effective amendment shall be
                    deemed to be a new registration statement relating to the
                    securities offered therein, and the offering of such
                    securities at that time shall be deemed to be the initial
                    bona fide offering thereof.

               3.   To remove from registration by means of a post-effective
                    amendment any of the securities being registered which
                    remain unsold at the termination of the offering.

          (b)  The undersigned Registrant hereby undertakes that, for purposes
               of determining any liability under the Securities Act of 1933,
               each filing of the registrant's annual report pursuant to Section
               13(a) or Section 15(d) of the Securities Exchange Act of 1934
               (and, where applicable, each filing of an employee benefit plan's
               annual report pursuant to Section 15(d) of the Securities
               Exchange Act of 1934) that is incorporated by reference in the
               registration statement shall be deemed to be a new registration
               statement relating to the securities offered herein, and the
               offering of such securities at that time shall be deemed to be
               the initial bona fide offering thereof.

          (c)  Insofar as indemnification for liabilities arising under the
               Securities Act of 1933 may be permitted to directors, officers
               and controlling persons of the registrant pursuant to the
               foregoing provisions, or otherwise, the registrant has been
               advised that in the opinion of the Securities and Exchange
               Commission such indemnification is against public policy as
               expressed in the Act and is, therefore, unenforceable. In the
               event that a claim for indemnification against such liabilities
               (other than the payment by the registrant of expenses incurred or
               paid by a director, officer or controlling person of the
               registrant in the successful defense of any action, suit or
               proceeding) is asserted by such director, officer or controlling
               person in connection with the securities being registered, the
               registrant will, unless in the opinion of its counsel the matter
               has been settled by controlling precedent, submit to a court of
               appropriate jurisdiction the question whether such
               indemnification by it is against public policy as expressed in
               the Act and will be governed by the final adjudication of such
               issue.
