                               PROSPECTUS SUMMARY

Company Overview

      We are a single-source/turn-key provider of technology-based security
solutions for medium and large commercial and governmental agencies in the
United States. As a single-source/turn-key provider of diversified
technology-based integrated security solutions, we can expedite project
completion, optimize system performance and manpower performance. The
continually evolving security requirements of commercial and government
entities, together with rapidly advancing technology, provides numerous
opportunities for us to assist our clients with their security needs.

The Offering

      On November 5, 2001, the Company entered into an agreement with The Wall
Street Group, Inc. (the "Wall Street Group") for Wall Street Group to serve as
financial public relations counsel to the Company (the "Agreement"). Under the
Agreement, Wall Street Group was paid a monthly fee and reimbursed out-of-pocket
expenses, and earned options for the purchase of the Company's common stock. The
Agreement also provided Wall Street Group with the right to have the shares
issuable under the options to be registered for sale under the Securities Act of
1933. The Agreement further provided that any options earned by Wall Street
Group were to be granted to Wall Street Group's affiliate, Wall Street
Consultants, Inc. (the "Selling Shareholder"). Throughout the term of the
Agreement until its termination on April 6, 2003, Wall Street Group earned
options for the purchase of up to 45,996 shares of the Company's common stock.
This prospectus relates to the resale of the 45,996 shares issuable upon
exercise of the options earned under the Agreement.

Number of Shares Outstanding

      As of January 30, 2006, 5,889,399 shares of our common stock were issued
and outstanding.

                                   THE COMPANY

      We are a single-source/turn-key provider of technology-based security
solutions for medium and large commercial and governmental agencies in the
United States.

      Security Distributing and Marketing magazine (SDM) ranks the top 100
largest firms selling closed circuit TV (CCTV), access control and integrated
security systems. We were ranked No. 21 in SDM's Top Systems Integrators Report
published in 2005.

      As a single-source/turn-key provider of diversified technology-based
integrated security solutions, we can expedite project completion, optimize
system performance and manpower performance. The continually evolving security
requirements of commercial and government entities, together with rapidly
advancing technology, provides numerous opportunities for us to assist our
clients with their security needs.

      We believe that the following key attributes provide us with a sustainable
competitive advantage:

      o     Experience and expertise;

      o     Technological sophistication;

      o     Quality control; and

      o     Strong list of references.

                                       1





Our Strategy

      Our strategy consists of the following components: (1) Maintain and
develop long-term relationships with clients; (2) Focus on high value added
services; (3) Continue to expand our client base in targeted industries; (4)
Maintain a high level of technological sophistication; and (5) Sell additional
services to our established client base.

      Our three operating units are integration, evacuation planning and
specialty products.

Our Integration Solution

      At the beginning of each new client relationship, we designate one member
of our professional staff as the client service contact. This individual is the
point person for communications between the client and us and often acts, as the
client's project manager for all of its security needs. Our engagement may
include:

      o     Consulting and planning;

      o     Engineering and design;

      o     Systems installation and management;

      o     Systems training; and

      o     Maintenance and technical support.

Consulting and planning

      Security consulting and planning are the initial phases of determining a
security solution for a project. We have developed a planning process that
identifies all systems, policies and procedures that are required for the
successful operation of a security system that will both meet a client's current
needs and accommodate its projected future requirements. Our consulting and
planning process includes the following steps:

      o     Identify the client's objectives and security system requirements;

      o     Survey the site, including inventory of physical components and
            software and evaluation of client's existing infrastructure and
            security system;

      o     Assess and prioritize the client's vulnerabilities;

      o     Develop and evaluate system alternatives;

      o     Recommend a conceptual security plan design;

      o     Estimate the cost of implementing the conceptual plan; and

      o     Develop a preliminary implementation schedule.

                                        2





      As a result of this process, we provide the client with a master plan for
an effective security solution that addresses routine operating needs as well as
emergency situations.

      We believe that our comprehensive planning process enables our clients to
budget for their security requirements on a long-term basis, identify
opportunities for cost reduction and prepare for future risks.

Engineering and design

      The engineering and design process involves preparation of detailed
project specifications and working drawings by a team of our engineers, systems
designers and computer-aided design system operators. These specifications and
drawings detail the camera sensitivity requirements, layout of the control
center, placement of cameras, card readers and other equipment and electrical
requirements. Throughout our engineering and design process, our goal is to
understand our client's operational preferences in order to design a system that
is functional, cost-effective and accommodates our client's present and future
requirements. In addition, we attempt to incorporate our client's existing
personnel, equipment and other physical resources into the system design.

      When retained as a single-source provider for turnkey security solutions,
we select system components required under the specifications and drawings. We
recommend that our customers buy proven off-the-shelf devices and software and
resort to custom equipment when absolutely necessary.

      We have made a strategic decision not to represent any equipment
manufacturer exclusively, thereby maintaining objectivity and flexibility in
equipment selection. We believe that our technical proficiency with the products
of a wide range of manufacturers enables us to select components that will best
meet a project's requirements.

Systems installation and management

      Under the supervision of our project manager, our technicians install
hardware, integrate hardware and software, and validate and test the system.
Subcontractors typically perform other aspects of the system installation such
as electrical installation and basic construction.

      Components that may be integrated in a security system include the
following:

      o     Access control systems, which are designed to exclude unauthorized
            personnel from specified areas;

      o     Intrusion detection systems, which detect unauthorized door and
            window openings, glass breakage, vibration, motion, noise and alarms
            and other peripheral equipment;

      o     Closed circuit television systems, which monitor and record entry
            and exit activity or provide surveillance of designated areas;

      o     Critical condition monitoring systems, which provide alarm
            monitoring and supervision of various systems and facilities; and

      o     Fire detection systems, intercoms, public address and network
            connectivity that can expand a local security system into a closely
            controlled worldwide system.

                                        3





Systems training

      Upon the completion of a systems integration project, we typically will
provide the customer with system-documentation and training in the operation and
maintenance of the system.

Maintenance and technical support

      We provide maintenance and technical support services on a scheduled,
on-call, or emergency basis. These services include developing and implementing
maintenance programs both for security systems designed, engineered, or
integrated by us and for existing systems.

Our Emergency Preparedness Planning Program Solution

      Our Emergency Preparedness Planning Programs ("EPPP") division works with
companies and managers of high-rise office buildings to analyze their specific
facilities needs with emergency preparedness plans. We provide demonstrations,
training and recommendations to clients. Our EPPP division provides a wide array
of services, including:

      o     Development of emergency plans and procedures;

      o     Expand existing fire/emergency and preparedness response plans;

      o     Articulate building strategy to tenants;

      o     Provide tenant inclusion;

      o     Increase building community unity, awareness and confidence; and

      o     Employee training.

Our Specialty Products Solution

      The Company's specialty products solutions are provided by two
wholly-owned subsidiaries, Viscom Products, Inc. ("Viscom") and Airorlite
Communications, Inc. ("Airorlite"). Viscom has developed an integrated standard
solution for mobile digital recorders for deployment on municipal buses and
trains. This product is now being manufactured by a third party in accordance
with Viscom's standards. Airorlite specializes in the design, manufacture and
maintenance of wireless communications equipment used to enhance emergency radio
frequency services and cellular communication for both fixed and mobile
applications.

                 DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

      This prospectus and the documents incorporated by reference in this
prospectus contain "forward-looking statements" as defined by the Private
Securities Litigation Reform Act of 1995. The forward-looking statements include
certain statements pertaining to our capital resources, performance and results
of operations. In addition, all statements regarding anticipated growth in our
revenue, anticipated market conditions and results of operations are
forward-looking statements. To identify forward-looking statements look for
words like "believes," "expects," "may," "will," "should," "seeks," "intends,"
"plans," "estimates" or "anticipates" and similar words or phrases. Discussions
of strategy, plans or intentions often contain forward-looking statements.
These, and all forward-looking statements, necessarily depend on assumptions,
data or methods that may be incorrect or imprecise.

                                        4





      Such statements reflect the current views of the Company and its
management with respect to future events and are subject to certain risks,
uncertainties and assumptions. Should one or more of these risks or
uncertainties materialize, or should underlying assumptions prove incorrect, our
actual results, performance or achievements could differ materially from the
results expressed in, or implied by, these forward-looking statements.

      Our actual results may differ materially from the results predicted or
from any other forward-looking statements made by, or on behalf of, us and
reported results should not be considered as an indication of future
performance. The potential risks and uncertainties include, among other things,
those described under "Risk Factors" elsewhere in this prospectus.

      Although we believe that the expectations reflected in the forward-looking
statements are reasonable, we cannot guarantee future results, events, levels of
activity, performance, or achievements. We do not assume responsibility for the
accuracy and completeness of the forward-looking statements. We do not intend to
update any of the forward-looking statements after the date of this prospectus
to conform them to actual results.

                                  RISK FACTORS

      The securities offered hereby involve a high degree of risk. Investors
should carefully consider the risks and uncertainties described below, as well
as all of the other information contained in the disclosure documents included
in this memorandum. Any of the following risks could materially adversely affect
our business, financial condition or operating results and could adversely
affect the value of an investment in our common stock.

We may not be able to develop or acquire new technological solutions necessary
for our customers' requirements

      Our success depends on acquiring or developing new technology to satisfy
our customers' needs. Any failure or delay to deliver these advances on our part
could have a negative impact on our business.

We are dependent upon a small number of customers for a large portion of our
revenues

      We have a small number of customers from which we receive a large portion
of our revenues. Although, no single customer comprised more then 10% of total
revenues during 2004, our five largest projects represented approximately 25% of
our revenues. Revenues from governmental agencies accounted for 20% in 2004
versus 21% in 2003. Consequently, we are often required to replace one customer
with one or more other customers in order to generate the same amount of
revenues. There can be no assurance that we will continue to be able to do so.

Some of our orders and contracts may be cancelled or modified so there is risk
that our full backlog may not be realized

      Some of our orders and contract backlog are subject to cancellation and
modification by our customers so we cannot be certain that we will recognize the
full value of our backlog. As of September 30, 2005, our backlog was
approximately $14,802,000.

                                        5





We are dependent on a few vendors, and we rely on timely deliveries of equipment
from all outside sources

      There are a few vendors from whom we obtain devices and software for
specific access control and imaging, remote transmission, smart key and mobile
applications. The loss of any one of these companies as suppliers could have a
material adverse impact on our business, financial condition and results of
operations if we are unable to develop or acquire new technologies from other
sources. While we believe alternative vendors are available, we have not yet
identified them.

      Timely vendor deliveries of equipment meeting our stringent
quality-control standards from all suppliers are also important to our business
because each installed system requires a variety of elements to be fully
functioning. The failure to deliver any critical device or component, when
needed, in operating condition, can delay a project, trigger vendor penalties,
halt progress payments or result in cancellation of a contract or order.

We experience intense competition for business from a variety of sources

      In systems integration, we compete for new business with large
construction firms, electrical contractors, and consultants in the security
business and other systems integrators. Many of our competitors are much larger
than we are and have greater resources. In order to effectively compete in the
future, we may have to charge less for our services that may result in lower
profit margins.

We rely on only a few key executives

      James E. Henry and Irvin F. Witcosky, our two executives, are vital to our
business operations. The loss of any one of them could have a material adverse
impact on our business, financial condition or results of operations.

Our business and growth will suffer if we are unable to hire and retain highly
skilled personnel

      Competition for highly skilled employees is intense in our industry. The
design and the installation of our systems requires substantial technical
capabilities in many disparate disciplines from mechanics and computer science
to electronics and advanced software. Our future success depends on our ability
to attract, train, motivate and retain highly skilled employees. If we are
unable to hire and retain skilled personnel, our growth may be restricted, the
quality of our products and services diminished and our sales and the value of
your investment reduced. We may be unable to retain our skilled employees or
attract, assimilate and retain other highly skilled employees in the future.

We have not been consistently profitable and may not be profitable in the future

      For the years ended December 31, 2003 and 2004 our sales were $18,261,065
and $29,725,718, respectively, and our net income (loss) was ($2,957,102) and
$44,021, respectively. Our profitability has not been continuous and we can make
no assurance that we will be profitable in the future.

Our quarterly results will continue to fluctuate

      Our quarterly results have varied significantly in the past and will
likely continue to do so in the future due to a variety of factors, including
the timing and nature of projects from which revenues are recognized during any
particular quarter. Such fluctuations may contribute to the volatility in the
market price for our common stock.

                                        6





Lengthy sales cycle

      Sale of our services and products frequently involves a substantial
commitment of resources to evaluate a potential project and prepare a proposal.
In addition, approval of proposals often involves a lengthy process due to
clients' internal procedures and capital expenditure approval processes. We may
not be awarded a project that we have prepared a proposal for and, even if we
are, a substantial period of time may elapse from when we made the proposal to
when we recognize sales from the project.

We may make acquisitions or form joint ventures that are unsuccessful

      Part of our growth strategy may involve acquisitions or joint ventures
with other system integrators. This strategy is subject to the following risks:

      o     We may not be able to identify suitable acquisition and joint
            venture candidates.

      o     If the purchase price of an acquisition includes cash, we may need
            to use a significant portion of our available cash.

      o     Even if we make an acquisition of a company or form a joint venture,
            we could have difficulty assimilating the acquired company's
            operations and personnel or working with the joint venture. These
            difficulties could disrupt our ongoing business, distract our
            management and employees and increase our expenses and charges, and,
            thus, could have a material impact on our business, financial
            condition and results of operations.

      o     We may not be able to retain key employees of the acquired companies
            or maintain good relations with its customers or suppliers.

      o     We may be required to incur additional debt.

      o     We may be required to issue equity securities to pay for
            acquisition, which will dilute existing shareholders.

      o     We may have to incur significant accounting charges, such as
            impairment of intangible assets, which may adversely affect our
            results of operations.

We have limited cash and may not be able to receive additional financing

      As of September 30, 2005, we had approximately $714,489 in cash. We
believe that this, together with anticipated cash flows from operation and
amounts available under our $4 million revolving line of credit with our bank
will be sufficient to satisfy our working capital requirements for the
foreseeable future. However, we may need to seek additional financing sooner
than we anticipate as a result of factors including but not limited to the
following:

      o     changes in operating plans

      o     lower than anticipated sales

      o     increased operating costs; and

      o     potential acquisitions

                                        7





      However, additional financing may not be available on commercially
reasonable terms, if at all.

Our Chief Executive Officer and Chief Operating Officer own the majority of our
common stock and their interests may be different from and conflict with yours

      Mr. Henry and Mr. Witcosky beneficially own a total of approximately
47.54% of our outstanding common stock, without taking into account shares
issuable under common stock purchase warrants and stock options. Accordingly, if
they act together, they will have the power to control the election of all of
our directors and other issues for which the approval of our shareholders is
required.

Our stock price may fluctuate, which may make it difficult to resell your shares
at attractive prices

      The market price of our common stock may be highly volatile. The market
prices of securities of other technologically oriented companies of similar size
have been extremely volatile. Factors that could cause volatility in our stock
price include:

      o     fluctuations in our quarterly operating results;

      o     changes in the market valuations of other security or technology
            companies and stock market prices and volume fluctuations generally;

      o     economic conditions specific to the security industry;

      o     announcements by us or our competitors relating to new services or
            technologies, significant acquisitions, strategic relationships,
            joint ventures or capital commitments;

      o     applicable regulatory developments; and

      o     additions or departures of our key personnel.

The trading volume in our common stock fluctuates and as a result you may find
it difficult to sell your shares of our common stock

      Our common stock is listed on the American Stock Exchange. Trading in our
common stock fluctuates and on some trading days is minimal. Failure to maintain
an active trading market in our common stock could negatively affect the price
of our common stock and your ability to sell our common stock.

      If we are delisted from the American Stock Exchange, you may also find it
more difficult to trade our common stock due to "penny stock" rules.

      If we are unable to satisfy the requirements for continued listing on the
American Stock Exchange, trading, if any, in our common stock would be conducted
in the over-the-counter market in what is commonly referred to as the "pink
sheets" or on the OTC Bulletin Board. In this event, it may be extremely
difficult to sell or trade our common stock.

Availability of significant amount of our common stock for sale could cause its
market price to decline

      If our stockholders sell substantial amounts of our common stock in the
public market following this offering or the perception exists that such sales
could occur, including shares issued upon exercise of outstanding common stock
purchase options, the market price of our common stock could fall.

                                        8





      As of January 30, 2006, there were 5,889,399 shares of our common stock
issued and outstanding. An additional 45,996 shares issuable under outstanding
options are being registered for resale under this prospectus. A sale of all or
a significant portion of these shares could have an adverse impact on our stock
price.

                                 USE OF PROCEEDS

      If the options are issued to the Selling Stockholder, we would receive a
maximum of $321,372 as a result of such exercises. Notwithstanding, there is no
assurance the options will be exercised. If we receive any proceeds from the
exercised options, these proceeds will be used for general working capital
purposes. The net proceeds from the sale of the securities covered by this
prospectus will be received by the Selling Shareholder. We will not receive any
of the proceeds from any sale by the Selling Shareholder of the securities
covered by this prospectus.

                               SELLING SHAREHOLDER

      The following table sets forth, as of January 30, 2006, information as to
the shares of common stock that may be sold in this offering by the Selling
Shareholder. Because the Selling Shareholder may offer all or a portion of the
shares of common stock offered by this prospectus at any time and from time to
time after the date hereof, we cannot predict the number of shares that the
Selling Shareholder may retain upon completion of this offering. In the table
below, the percentage ownership after the offering is based upon the assumed
sale by the Selling Shareholder of all shares it may offer for sale pursuant to

                              PLAN OF DISTRIBUTION

      The Selling Shareholder, which as used herein includes donees, pledgees,
transferees or other successors-in-interest selling shares of common stock or
interests in shares of common stock received after the date of this prospectus
from a selling stockholder as a gift, pledge, partnership distribution or other
transfer, may, from time to time, sell, transfer or otherwise dispose of any or
all of its shares of common stock or interests in shares of common stock on any
stock exchange, market or trading facility on which the shares are traded or in
private transactions. These dispositions may be at fixed prices, at prevailing
market prices at the time of sale, at prices related to the prevailing market
price, at varying prices determined at the time of sale, or at negotiated
prices.

      The Selling Shareholder may use any one or more of the following methods
when disposing of shares or interests therein:

      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     short sales effected after the date the registration statement of
            which this prospectus is a part is declared effective by the SEC;

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

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

      o     a combination of any such methods of sale; and

      o     any other method permitted pursuant to applicable law.

      The Selling Shareholder may, from time to time, pledge or grant a security
interest in some or all of the shares of common stock owned by it and, if they
default in the performance of their secured

                                       10





obligations, the pledgees or secured parties may offer and sell the shares of
common stock, from time to time, under this prospectus, or under an amendment to
this prospectus under Rule 424(b)(3) or other applicable provision of the
Securities Act amending the list of Selling Shareholder to include the pledgee,
transferee or other successors in interest as selling stockholders under this
prospectus. The Selling Shareholder also may transfer the shares of common stock
in other circumstances, in which case the transferees, pledgees or other
successors in interest will be the selling beneficial owners for purposes of
this prospectus.

      In connection with the sale of our common stock or interests therein, the
Selling Shareholder 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
Shareholder 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. The Selling
Shareholder may also enter into option or other transactions with broker-dealers
or other financial institutions or the creation of one or more derivative
securities which require the delivery to such broker-dealer or other financial
institution of shares offered by this prospectus, which shares such
broker-dealer or other financial institution may resell pursuant to this
prospectus (as supplemented or amended to reflect such transaction).

      The aggregate proceeds to the Selling Shareholder from the sale of the
common stock offered by it will be the purchase price of the common stock less
discounts or commissions, if any. The Selling Shareholder reserves the right to
accept and, together with its agents from time to time, to reject, in whole or
in part, any proposed purchase of common stock to be made directly or through
agents. We will not receive any of the proceeds from this offering. Upon any
exercise of the warrants by payment of cash, however, we will receive the
exercise price of the warrants.

      The Selling Shareholder also may resell all or a portion of the shares in
open market transactions in reliance upon Rule 144 under the Securities Act of
1933, provided that it meets the criteria and conform to the requirements of
that rule.

      The Selling Shareholder and any underwriters, broker-dealers or agents
that participate in the sale of the common stock or interests therein may be
"underwriters" within the meaning of Section 2(11) of the Securities Act. Any
discounts, commissions, concessions or profit they earn on any resale of the
shares may be underwriting discounts and commissions under the Securities Act.
Selling shareholders who are "underwriters" within the meaning of Section 2(11)
of the Securities Act will be subject to the prospectus delivery requirements of
the Securities Act.

      To the extent required, the shares of our common stock to be sold, the
names of any selling shareholders, the respective purchase prices and public
offering prices, the names of any agents, dealer or underwriter, any applicable
commissions or discounts with respect to a particular offer will be set forth in
an accompanying prospectus supplement or, if appropriate, a post-effective
amendment to the registration statement that includes this prospectus.

      In order to comply with the securities laws of some states, if applicable,
the common stock may be sold in these jurisdictions only through registered or
licensed brokers or dealers. In addition, in some states the common stock may
not be sold unless it has been registered or qualified for sale or an exemption
from registration or qualification requirements is available and is complied
with.

      We have advised the Selling Shareholder that the anti-manipulation rules
of Regulation M under the Exchange Act may apply to sales of shares in the
market and to the activities of the Selling Shareholder and its affiliates. In
addition, we will make copies of this prospectus (as it may be supplemented or
amended from time to time) available to the Selling Shareholder for the purpose
of

                                       11





satisfying the prospectus delivery requirements of the Securities Act. The
Selling Shareholder may indemnify any broker-dealer that participates in
transactions involving the sale of the shares against certain liabilities,
including liabilities arising under the Securities Act.

      We have agreed to indemnify the Selling Shareholder against liabilities,
including liabilities under the Securities Act and state securities laws,
relating to the registration of the shares offered by this prospectus.

      We have agreed with the Selling Shareholder to keep the registration
statement of which this prospectus constitutes a part effective until the
earlier of (1) such time as all of the shares covered by this prospectus have
been disposed of pursuant to and in accordance with the registration statement
or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the
Securities Act.

   Holders of our common stock are entitled to one vote for each share held on

may be adversely affected by, the rights of the holders of shares of any series
of preferred stock which we may designate and issue in the future. No shares of
preferred stock are presently outstanding and as of the date of this prospectus,
we do not have any present plan to issue any shares of preferred stock.

Anti-Takeover Effects of Provisions of Delaware Law

   Section 203 of the Delaware General Corporation Law contains provisions that
may make the acquisition of control of our company by means of a tender offer,
open market purchase, proxy fight or otherwise, more difficult. We must comply
with the provisions of this law. In general, Section 203 prohibits a publicly
held Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner.

   A "business combination" includes a merger, asset sale or other transaction
resulting in a financial benefit

                                       12





to the interested stockholder. An "interested stockholder" is a person who,
together with affiliates and associates, owns, or, in some cases, within three
years prior, did own, 15% or more of the corporation's voting stock. Under
Section 203, a business combination between us and an interested stockholder is
prohibited unless it satisfies one of the following three conditions:

      o     our board of directors must have previously approved either the
            business combination or the transaction that resulted in the
            stockholder becoming an interested stockholder;

      o     upon consummation of the transaction that resulted in the
            stockholder becoming an interested stockholder, the interested
            stockholder owned at least 85% of our voting stock outstanding at
            the time the transaction commenced, excluding, for purposes of
            determining the number of shares outstanding, shares owned by (1)
            persons who are directors and also officers and (2) employee stock
            plans, in some instances; and

      o     the business combination is approved by our board of directors and
            authorized at an annual or special meeting of the stockholders by
            the affirmative vote of the holders of at least 66 2/3% of our
            outstanding voting stock that is not owned by the interested
            stockholder.

                                  LEGAL MATTERS

      Certain legal matters with respect to the securities will be passed upon
for us by Milberg Weiss Bershad & Schulman LLP, One Pennsylvania Plaza, New
