      When used in this prospectus and any prospectus supplement, the terms "the
Company," "we," "our," and "us" refer to Universal Security Instruments, Inc.
and its subsidiaries. The following summary contains basic information about us.
It likely does not contain all the information that is important to you. We

referred you in this prospectus.

Securities Registered

      This prospectus relates to the sale of up to 332,719 shares of our common
stock by Michael L. Kovens in open-market transactions effectuated on American
Stock Exchange or in privately negotiated transactions, as more completely
described in the section titled "Plan of Distribution" on page 6 of this
prospectus.

The Company

      Universal Security Instruments, Inc. designs and markets a variety of
popularly-priced safety products consisting primarily of smoke alarms, carbon
monoxide alarms and related products. Most of our products require minimal
installation and are designed for easy installation by the consumer without
professional assistance, and are sold through retail stores. We also market
products to the electrical distribution trade through our wholly-owned
subsidiary, USI Electric, Inc. ("USI Electric"). The electrical distribution
trade includes electrical and lighting distributors as well as manufactured
housing companies. Products sold by USI Electric usually require professional
installation.

      Prior to 2000, we also designed and marketed a variety of
telecommunication and video products. Due to the low margins realized on our
telecommunications and video products, we have since focused our business
primarily on safety products. As a result, we (i) changed our marketing of
telecommunications and video products to concentrate virtually exclusively on
made-to-order private label sales, and (ii) entered into the electrical
distribution market with an enhanced and newly packaged line of smoke alarms as
well as our other safety products.

      In 1989 we formed a limited liability company under the laws of Hong Kong,
as a joint venture with a Hong Kong-based partner to manufacture various
products in the Peoples Republic of China (the "Hong Kong Joint Venture"). We
currently own a 50% interest in the Hong Kong Joint Venture and are a
significant customer of the Hong Kong Joint Venture.

      Universal Security Instruments, Inc. was incorporated in Maryland in 1969.
Our principal executive office is located at 7-A Gwynns Mill Court, Owings
Mills, Maryland 21117, and our telephone number is 410-363-3000. Information
about us may be obtained from our website www.universalsecurity.com. Copies of
our Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports
on Form 8-K, are available free of charge on our website as soon as they are
filed with the Securities and Exchange Commission (SEC) through a link to the
SEC's EDGAR reporting system. Simply select the "Investor Relations" menu item,
then click on the "SEC Filings" link. The SEC's EDGAR reporting system can also
be accessed directly at www.sec.gov.

                                  RISK FACTORS

      Before you decide to invest, you should consider carefully the risks
described below, together with the other information contained or incorporated
by reference in this prospectus. Any or all of these factors, or others not
mentioned below, could affect our business or our prospects. The risks and
uncertainties we have described below are not the only ones facing our company.
Additional risks and uncertainties not presently known to us or that we
currently deem immaterial may also affect our business operations.

      In addition, you should carefully consider the information incorporated by
reference and the information that we file with the SEC from time to time. If
any of the following risks actually occur, our business could be materially
adversely affected. In such case, the trading price of our common stock could
decline, and you may lose all or part of your investment. The information in
this prospectus is complete and accurate as of the date on the front cover of
this prospectus, but the information may change after such date.

      This section includes or refers to forward-looking statements. You should

forward-looking statements in the section of this prospectus entitled
"Cautionary Statement Regarding Forward-Looking Statements," on page 5 of this
prospectus.

RISK FACTORS RELATING TO OUR BUSINESS GENERALLY

Our success depends to a very large degree on our relationship with and the
success of our Hong Kong Joint Venture.

            During fiscal year 2005, 68% of our total inventory purchases were
made from the Hong Kong Joint Venture. The products produced by the Hong Kong
Joint Venture include smoke alarms and carbon monoxide alarms, and we are
currently pursuing the development of additional products to be manufactured by
the Hong Kong Joint Venture. Our purchases from the Hong Kong Joint Venture
represented approximately 40.66% of the Hong Kong Joint Venture's total sales
during fiscal 2005, with the balance of the Hong Kong Joint Venture's sales
being primarily made in Europe and Australia to unrelated customers. If the Hong
Kong Joint Venture does not maintain profitability, our profitability will be
adversely affected.

            The Hong Kong Joint Venture has filed an application for an initial
public offering (IPO) and listing on the Hong Kong Stock Exchange Main Board. No
assurances can be given that these steps will result in an initial public
offering for the Hong Kong Joint Venture. Should the Hong Kong Joint Venture
complete its IPO, our ownership of the Hong Kong Joint Venture will be reduced,
which could reduce the value of our investment in the Hong Kong Joint Venture.

            In addition, adverse changes in our relationship with our Hong Kong
Joint Venture partners could unfavorably affect the value of our investment in
the Hong Kong Joint Venture and could have a material adverse effect on our
ability to purchase products for distribution.

Our reliance on the Hong Kong Joint Venture exposes us to uncertainties and
risks from abroad which could negatively affect our operations and sales.

            Our relationship with the Hong Kong Joint Venture and our and the
Hong Kong Joint Venture's sales in other countries expose us to particular
risks. The following are among the risks that could negatively affect our
imports and our and the Hong Kong Joint Venture's sales in foreign markets:

      o     new restrictions on access to markets,
      o     currency devaluation,
      o     new tariffs,
      o     adverse changes in monetary and/or tax policies,
      o     inflation, and
      o     governmental instability.

            Should any of these risks occur, the value of our investment in the
Hong Kong Joint Venture could be reduced and our results of operations could be
negatively impacted.

The lack of availability of inventory could adversely affect our financial
results.

            We source inventory primarily from our Hong Kong Joint Venture,
which has manufacturing facilities in the People's Republic of China. Our
purchases of inventory are subject to being affected by a number of factors,
namely, production capacity, labor unrest and untimely deliveries. Changes in
economic and political conditions in China or any other adversity to the Hong
Kong Joint Venture will unfavorably affect the value of our investment in the
Hong Kong Joint Venture and could have a material adverse effect on the our
ability to purchase products for distribution.


                                      -2-


Our Hong Kong Joint Venture is subject to political and economic factors unique
to China.

            The Chinese government has been reforming the Chinese economic
system. In recent years, the government has also begun reforming the government
structure. These reforms have resulted in significant economic growth and social
progress. Although the majority of the production assets in China are still
state-owned, economic reform policies have emphasized autonomous enterprises and
the utilization of market mechanisms. Our Hong Kong Joint Venture currently
expects that the Chinese government will continue its reform by further reducing
governmental intervention in business enterprises and allowing market mechanisms
to allocate resources. Any adverse changes in political, economic or social
conditions in China could have a material adverse effect on the Hong Kong Joint
Venture's operations and our financial results, as well as our ability to
purchase products manufactured by the Hong Kong Joint Venture.

We are subject to risks in connection with the importation of our products from
foreign countries.

            We import all of our products. As an importer, we are subject to
numerous tariffs which vary depending on types of products and country of
origin, changes in economic and political conditions in the country of
manufacture, potential trade restrictions and currency fluctuations. We have
attempted to protect ourselves from fluctuations in currency exchange rates to
the extent possible by negotiating commitments in U.S. dollars. We are also
subject to strikes or other labor unrest at points of origin and destination, as
well as delays and restrictions which impact shipping and shipping routes.

We rely on our key personnel and the loss of one or more of those personnel
could have a material adverse effect on our business, financial condition and
results of operations.

            Our operations and prospects depend in large part on the performance
of our senior management team. There can be no assurance that we would be able
to find qualified replacements for any of these individuals if their services
were no longer available. The loss of the services of one or more members of our
senior management team could have a material adverse effect on our business,
financial condition, and results of operations.

Our competition is both intense and varied and our failure to effectively
compete could adversely affect our prospects.

            In fiscal year 2005, our sales of safety products accounted for
approximately 99.6% of our total sales. Many of our competitors have greater
financial resources and financial strength than we have. Some of our competitors
may be willing to reduce prices and accept lower profit margins to compete with
us. While we believe that our safety products compete favorably with other such
products in the market, primarily on the basis of styling, features, and
pricing, the safety industry in general involves changing technology. The
success of our products may depend on our ability to improve and update our
products in a timely manner and to adapt to new technological advances. As a
result of this competition, we could lose market share and suffer losses, which
could have a material adverse effect on our future financial performance.

The security products marketplace is dynamic and challenging because of the
introduction of new products and services.

            We must constantly introduce new products, services, and product
features to meet competitive pressures. We may be unable to timely change our
existing merchandise sales mix in order to meet these competitive pressures,
which may result in increased inventory costs or loss of market share.

Adverse changes in national or regional U.S. economic conditions could adversely
affect our financial results.

            We market our products nationally to retailers, including wholesale
distributors, chain, discount, and home center stores, catalog and mail order
companies and to other distributors. Overall consumer confidence, consumer
credit availability, recessionary trends, housing starts and prices, mortgage
rates, and consumers' disposable income, and spending levels directly impact our
sales. Negative trends, whether national or regional in nature, in any of these
economic conditions could adversely affect our financial results.


                                      -3-


Our products must meet specified quality and safety standards to enter and stay
on the market.

            Our smoke and carbon monoxide alarms must meet U.S. and various
international standards before they are sold. For example, in the United States,
our products must be certified by Underwriters Laboratories (UL) and similar
certifications must be obtained in each country where we compete for market
share. If our manufacturers' products or manufacturing facilities (including
those of the Hong Kong Joint Venture) fail to pass periodic inspections, the
approval certificates for the relevant products may be suspended until
corrections are made. Loss of UL or other independent certifications could have
a material adverse affect on our sales and financial results.

Our products expose us to the potential of product liability claims.

            We do not manufacture any of our own products. All of our products
are manufactured by the Hong Kong Joint Venture or others. Nevertheless, we
could be named as a defendant in an action arising from damages suffered as a
result of one of our products. While we carry products liability insurance, to
the extent we are found liable for damages for which we are uninsured, our
profitability may be adversely affected. Any suit, even if not meritorious or if
covered by an indemnification obligation, could result in the expenditure of a
significant amount of our financial and managerial resources and could create
significant negative publicity for us and our products.

We may be unable to successfully execute our merchandising and marketing
strategic initiatives.

            We are focusing our sales and marketing efforts and initiatives to
maximize safety product sales, especially smoke alarms and carbon monoxide
alarms manufactured by our Hong Kong Joint Venture and marketed to the
electrical distribution and retail trade. If we fail to successfully execute
these initiatives, our business could be adversely affected.

We are and could become subject to litigation regarding intellectual property
rights, which could seriously harm our business.

            We design most of our security products and contract with suppliers
to manufacture those products and deliver them to us. We have been the subject
of lawsuits by third parties which assert against us infringement claims or
claims that we have violated a patent or infringed upon a copyright, trademark
or other proprietary right belonging to them. If such infringement by our
suppliers or us were found to exist, we could be subject to monetary damages and
an injunction preventing the use of their intellectual property. If one of our
products were found to infringe, we may attempt to acquire a license or right to
use such technology or intellectual property, which could result in higher
manufacturing costs. Any infringement claim, even if not meritorious and/or
covered by an indemnification obligation, could result in the expenditure of a
significant amount of our financial and managerial resources.

If governmental regulations change or are applied differently, our business
could suffer.

The sales of our smoke and carbon monoxide alarms are impacted by local laws and
regulations mandating the installation of these security devices in new and
sometimes existing homes and buildings. Changes in these consumer safety
regulations, both in the United States and abroad, could impact our business.

RISK FACTORS RELATING TO OUR ARTICLES OF INCORPORATION AND OUR STOCK

The liability of our directors is limited.

            Our Articles of Incorporation limit the liability of directors to
the maximum extent permitted by Maryland law.

It is unlikely that we will issue dividend son our common stock in the
foreseeable future.

            We have not declared or paid cash dividends on our common stock in
over 20 years and do not intend to pay cash dividends in the foreseeable future.
The payment of dividends in the future will be at the discretion of our board of
directors.


                                      -4-


The exercise of outstanding options will dilute the percentage ownership of our
stockholders, and any sales in the public market of shares of our common stock
underlying such options may adversely affect prevailing market prices for our
common stock.

            As of the date of this Prospectus, there are outstanding options to
purchase an aggregate of 235,329 shares of our common stock at per share
exercise prices ranging from $0.98 to $15.02. The exercise of such outstanding
options would dilute the percentage ownership of our existing stockholders, and
any sales in the public market of shares of our common stock underlying such
options may adversely affect prevailing market prices for our common stock.

The Selling Stockholder may choose to sell shares at prices below the current
trading price.

            The Selling Stockholder is not restricted as to the prices at which
he may sell his shares of our common stock. Sales of shares of our common stock
below the then-current trading prices may adversely affect the market price of
our common stock.

It may be difficult for a third party to acquire us, which could affect our
stock price.

            Our charter and Bylaws contain certain anti-takeover provisions
pursuant to the Maryland General Corporation Law. This means that we may be a
less attractive target to a potential acquirer who otherwise may be willing to
pay a premium for our common stock above its market price.

            CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

      We have made forward-looking statements (as such term is defined in the
Private Securities Litigation Reform Act of 1995) in this document and in
documents that are incorporated by reference in this document that are subject
to risks and uncertainties. We caution you to be aware of the speculative nature
of forward-looking statements. Forward-looking statements include the
information concerning possible or assumed future results of our operations.
Also, statements including words such as "believes," "expects," "anticipates,"
"intends," "plans," "estimates," or similar expressions are forward-looking
statements. These statements reflect our good faith belief based on current
expectations, estimates, and projections about (among other things) the industry
and the markets in which we operate, but they are not guarantees of future
performance. Purchasers of shares offered hereby should note that many factors,
some of which are discussed elsewhere in this document and in the documents
incorporated by reference in this document, could affect our future financial
results and could cause actual results to differ materially from those expressed
in forward-looking statements contained or incorporated by reference in this
document. Important factors that could cause actual results to differ materially
from the expectations reflected in the forward-looking statements in this
prospectus include, among others, the factors set forth under the caption "Risk
Factors," general economic, business and market conditions, changes in laws, and
increased competitive pressure. We can give no assurances that the actual
results we anticipate will be realized or, even if substantially realized, that
they will have the expected consequences to, or effects on, us or our business
or operations. Except as required by applicable laws, we do not intend to
publish updates or revisions of any forward-looking statements we make to
reflect new information, future events or otherwise.

                                 USE OF PROCEEDS

      We will not receive any proceeds from the sale of the shares of common
stock by the Selling Stockholder.

                               SELLING STOCKHOLDER

      We prepared the information set forth in this section based on information
supplied to us by the Selling Stockholder. However, since the date of this
prospectus, the Selling Stockholder may have sold or transferred some or all of
his shares in transactions exempt from registration under the Securities Act or
may have acquired additional shares. The shares covered by this prospectus may
be offered from time to time by the Selling Stockholder. Information concerning
the Selling Stockholder may change from time to time, and changed information
will be presented in a supplement to this prospectus if and when necessary.


                                      -5-


      Michael L. Kovens is the only selling stockholder participating in this
offering. As of the date of this prospectus, Mr. Kovens is the beneficial owner
of 332,719 shares, which is 19.9% of our outstanding common stock. Following the
sale of all of the shares of our common stock offered pursuant to this
prospectus, Mr. Kovens will not beneficially own any shares our common stock.

      Until September 2003, Mr. Kovens served as a member of our Board of
Directors.

      Mr. Kovens acquired 20,000 shares of the stock offered in this prospectus
for $2.25 per share on July 12, 2005, as the result of the exercise on June 6,
2002 of a nonqualified option dated June 11, 1997.

      As reported in our Annual Report on Form 10-K, Mr. Kovens filed an action
in Baltimore County Circuit Court (Case No. C-03-9639) against us and our other
directors, alleging various claims and seeking various relief, including damages
from our President and the Estate of our former Chairman in the amount of $20
million, and an additional $500,000 from us with respect to the exercise of the
option for the purchase of 20,000 shares at $2.25 per share (mentioned above),
which we maintain had expired.

      On July 12, 2005, we entered into an agreement with Mr. Kovens in which we
agreed, among other things, to file the registration statement of which this
prospectus forms a part and to recognize the exercise of the stock option
referred to above. Mr. Kovens agreed to not stand for election as a director and
released us and our directors from all claims asserted in or relating to the
lawsuit he filed against us.

      According to information supplied to us by the Selling Stockholder, the
Selling Stockholder is not a broker-dealer or an affiliate of a broker-dealer
nor, at the time he acquired the shares of our common stock offered in this
Prospectus, did the Selling Stockholder have any agreements or understandings,
directly or indirectly, with any person to distribute those shares.

                              PLAN OF DISTRIBUTION

      The Selling Stockholder and his successors by the laws of descent and
distribution may, from time to time, sell any or all of the shares covered by
this prospectus. The Selling Stockholder will act independently of us in making
decisions with respect to the timing, manner, and size of each sale.

      The Selling Stockholder may sell shares of common stock directly to
purchasers from time to time. Alternatively, he may from time to time offer the
common stock to or through broker-dealers or agents, who may receive
compensation in the form of concessions or commissions from the Selling
Stockholder or the purchasers of such common stock for whom they may act as
agents.

      Such sales may be made on any stock exchange (including the American Stock
Exchange), quotation system, 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 Stockholder may use any one or more of the following methods
when selling shares:

o     ordinary brokerage transactions and transactions in which the
      broker-dealer solicits purchasers;

o     block trades in which the broker-dealer will attempt to sell the shares as
      agent but may position and resell a portion of the block as principal to
      facilitate the transaction;

o     purchases by a broker-dealer as principal and resale by the broker-dealer
      for its account;

o     an exchange distribution in accordance with the rules of the applicable
      exchange;

o     privately negotiated transactions;

o     an exchange distribution in accordance with the rules of the applicable
      exchange;

o     settlement of short sales entered into after the date of this prospectus;


                                      -6-


o     broker-dealers may agree with the Selling Stockholder to sell a specified
      number of such shares at a stipulated price per share;

o     through the writing or settlement of options or other hedging
      transactions, whether through an options exchange or otherwise;

o     a combination of any such methods of sale; or

o     any other method permitted pursuant to applicable law.

      The Selling Stockholder may also sell shares under Rule 144 under the
Securities Act, if available, rather than under this prospectus.

      Broker-dealers engaged by the Selling Stockholder may arrange for other
broker-dealers to participate in sales. Broker-dealers may receive commissions
or discounts from the Selling Stockholder (or, if any broker-dealer acts as
agent for the purchaser of shares, from the purchaser) in amounts to be
negotiated. The Selling Stockholder does not expect these commissions and
discounts relating to his sales of shares of our common stock to exceed what is
customary in the types of transactions involved.

      In connection with the sale of our common stock or interests therein, the
Selling Stockholder may enter into hedging transactions with broker-dealers or
other financial institutions, which may in turn engage in short sales of the
common stock in the course of hedging the positions they assume. The Selling
Stockholder may also sell shares of our common stock short and deliver these
securities to close out their short positions, or loan or pledge the common
stock to broker-dealers that in turn may sell these securities.

      Upon us being notified in writing by the Selling Stockholder that any
material arrangement has been entered into with a broker-dealer for the sale of
common stock through a block trade, special offering, exchange distribution or
secondary distribution or a purchase by a broker or dealer, a supplement to this
prospectus will be filed, if required, pursuant to Rule 424(b) under the
Securities Act, disclosing (i) the name of the participating broker-dealer(s),
(ii) the number of shares involved, (iii) the price at which the shares of
Common Stock were sold, (iv) the commissions paid or discounts or concessions
allowed to such broker-dealer(s), where applicable, (v) that such
broker-dealer(s) did not conduct any investigation to verify the information set
out or incorporated by reference in this prospectus, and (vi) other facts
material to the transaction. In addition, upon us being notified in writing by
the personal representative of the Selling Stockholder that distributions from
the Selling Stockholder's estate have been made and a beneficiary intends to
sell more than 500 shares covered by this prospectus, a supplement to this
prospectus will be filed if then required in accordance with applicable
securities laws.

      The Selling Stockholder 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 such sales. In such 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. Discounts, concessions, commissions and
similar selling expenses, if any, that can be attributed to the sale of the
shares will be paid by the Selling Stockholder and/or the purchasers. The
Selling Stockholder has informed us that he does not have any agreement or
understanding, directly or indirectly, with any person to distribute the common
stock. There is no underwriter or coordinating broker acting in connection with
the proposed sale of our common stock by the Selling Stockholder. Because the
Selling Stockholder may be deemed to be an "underwriter" within the meaning of
the Securities Act, he will be subject to the prospectus delivery requirements
of the Securities Act. We have informed the Selling Stockholder of the need to
deliver a copy of this prospectus to each purchaser at or prior to the time of
the sale.

      We are required to pay certain fees and expenses incurred by us incident
to the registration of the shares.

      We have agreed to keep this prospectus effective until the earlier of the
date on which all of the shares offered in this prospectus have been sold
pursuant to this prospectus or one year from the date of this prospectus unless,
at any time during such one-year period, the closing price of our common stock,
as reported by the American Stock Exchange, is under ten dollars ($10.00) per


                                      -7-


share (as adjusted for stock splits, stock dividends or similar corporate
actions after July 1, 2005) for ten (10) consecutive trading days, in which
case, such one-year period will be extended to two years.

      Under applicable rules and regulations under the Exchange Act, any person
engaged in the distribution of the shares may not simultaneously engage in
market making activities with respect to our common stock for a period of two
business days prior to the commencement of the distribution. In addition, the
Selling Stockholder will be subject to applicable provisions of the Exchange Act
and the rules and regulations thereunder, including Regulation M, which may
limit the timing of purchases and sales of shares of our common stock by the
Selling Stockholder or any other person.

                 COMMISSION POSITION ON LIMITATION OF LIABILITY

      Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or persons controlling the
registrant pursuant to the foregoing provisions, the registrant has been
informed 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.

                                  LEGAL MATTERS

      The validity of the common stock being offered for sale hereby has been
passed on for us by Neuberger, Quinn, Gielen, Rubin & Gibber, P.A., Baltimore,

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 14. Other Expenses of Issuance and Distribution

      The following table sets forth the fees and expenses in connection with
the issuance and distribution of the securities being registered hereunder. All
such fees and expenses shall be borne by us. We do not expect that the Selling
Stockholder will pay any of the expenses of issuance and distribution in
connection with the offer and sale of the securities registered hereby other
than brokerage commissions and similar expenses incurred by him.

            Commission Registration Fee..................  $     700
            Legal Fees and Expenses......................      8,000
            Accounting Fees and Expenses.................      1,500
            Miscellaneous................................        500
            Total........................................  $  10,700

All of the above expenses, except the SEC registration fee, are estimates.

Item 15. Indemnification of Directors and Officers

      Maryland law permits us to include in our charter, and our charter
includes, a provision limiting the liability of our directors and officers to us
and our stockholders for money damages, except for liability resulting from a
director or officer's (a) actual receipt of an improper benefit or profit in
money, property or services or (b) active and deliberate dishonesty or an
intentionally wrongful, willful, or malicious act, established as such by a
finding that is material to a final judgment or other final adjudication adverse
to such director or officer.

      Maryland law requires us (unless our charter provides otherwise, which our
charter does not) to indemnify a director or officer who has been successful, on
the merits or otherwise, in the defense of any proceeding to which he is made a
party by reason of his service in that capacity. Maryland law permits us to, and
our bylaws require us to, indemnify our present and former directors and
officers against judgments, penalties, fines, settlements, and reasonable
expenses actually incurred by them in connection with any proceeding to which
they may be made a party by reason of their service in those or other capacities
unless it is established that:

o     the act or omission of the director or officer was material to the matter
      giving rise to the proceeding and (i) was committed in bad faith or (ii)
      was the result of active and deliberate dishonesty,

o     the director or officer actually received an improper personal benefit in
      money, property or services, or

o     in the case of any criminal proceeding, the director or officer had
      reasonable cause to believe that the act or omission was unlawful.

      A court may order indemnification if it determines that the director or
officer is fairly and reasonably entitled to indemnification, even though the
director or officer did not meet the prescribed standard of conduct or was
adjudged liable on the basis that personal benefit was improperly received.
However, indemnification for an adverse judgment in a suit by us or in our
right, or for a judgment of liability on the basis that personal benefit was
improperly received, is limited to expenses.

      In addition, Maryland law permits us to, and our bylaws require us to,
advance reasonable expenses to a director or officer upon receipt of (a) a
written affirmation by the director or officer of his good faith belief that he
has met the standard of conduct necessary for indemnification and (b) a written
undertaking by him or on his behalf to repay the amount paid or reimbursed if it
is ultimately determined that the standard of conduct was not met.

      Our bylaws also authorize our board of directors, to the maximum extent
permitted by Maryland law, to indemnify any employee or agent other than a
director or officer against any claim or liability arising from that status and
to pay or reimburse their reasonable expenses in advance of final disposition of
a proceeding.

Item 17. Undertakings

      (a) The 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 a 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;

Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply 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 15(d) of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), that are incorporated by reference in the registration
statement.

            (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed 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 that is incorporated by reference in the
registration statement 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.
