INTRUSION INC. AND SUBSIDIARIES        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

1. Description of Business

We develop, market and support a family of network intrusion prevention and detection systems and regulated information compliance systems that address vital
security issues facing organizations with mission critical business applications or housing classified, confidential, or customer information assets. We currently provide network security and
regulated information compliance solutions under our SecureNet family of hardware and software solutions.

We
market and distribute our products through a direct sales force to end-users, distributors and by numerous domestic and international system integrators, managed service
providers and value-added resellers. Our end-user customers include high technology, manufacturing, telecommunications, retail, transportation, health care, insurance, entertainment,
utilities and energy companies, government entities, financial institutions, and academic institutions.

We
were organized in Texas in September 1983 and reincorporated in Delaware in October 1995. For more than 15 years, we provided local area networking equipment and
were known as Optical Data Systems or ODS Networks. On April 17, 2000, we announced plans to sell, or otherwise dispose of, our networking divisions, which included our Essential Communications
division and our local area networking assets. In accordance with these plans, we have accounted for these businesses as discontinued operations. On June 1, 2000, we changed our name from ODS
Networks, Inc. to Intrusion.com, Inc., and our NASDAQ ticker symbol from ODSI to INTZ to reflect our focus on intrusion detection solutions. On November 1, 2001, we changed our
name from Intrusion.com, Inc. to Intrusion Inc.

Our
principal executive offices are located at 1101 East Arapaho Road, Richardson, Texas 75081, and our telephone number is (972) 234-6400. Our website URL is www.intrusion.com. Information contained
in or linked to our website are not a part of this report. References to "we," "us" and "our" in this report
refer to Intrusion Inc. and its subsidiaries.

As
of March 31, 2004, we had cash, cash equivalents and short-term investments in the amount of approximately $6.3 million, up from approximately
$2.7 million as of December 31, 2003. Although we believe we have sufficient cash resources to finance our operations and expected capital expenditures for the next twelve months, the
sufficiency of our cash resources may depend to a certain extent on general economic, financial, competitive or other factors beyond our control. Moreover, despite actions to reduce our costs and
improve our profitability, we expect our operating losses and net operating cash outflows to continue through at least the first half of 2004. As a result, we may not be able to achieve the revenue
and gross margin objectives necessary to achieve positive cash flow or profitability without obtaining additional financing. We do not currently have any arrangements for financing and we may not be
able to secure additional debt or equity financing on terms acceptable to us, or at all, at the time when we need such funding. If our business does not generate sufficient cash flow from operations
and sufficient future financings are not available, we may not be able to operate or grow our business, pay our expenses when due or fund our other liquidity needs.

On
March 25, 2004, we completed a $5.0 million private placement of 5% Convertible Preferred Stock and warrants. In the private placement, we sold 1,000,000 shares of
preferred stock at a price of $5.00 per share for gross proceeds of $5.0 million, less $275,000 of issuance costs. The preferred shares may be converted into 1,590,331 shares of common stock at
an initial conversion price of $3.144 per share. Included in this transaction were warrants to purchase 556,619 shares of common stock at an exercise price of $3.144 per share. In connection with the
closing of this private placement, we issued warrants to purchase 64,408 shares of our common stock at an exercise price of $3.144 per share to our financial advisor for assistance with the private
placement.

On
March 18, 2004, we filed an amendment to our certificate of incorporation to effect a four-for-one (4:1) reverse stock split of our common stock. The
reverse stock split became effective on March 29, 2004. All outstanding share numbers and related common stock numbers, such as earnings per share and outstanding options, included in this
report are set forth on a post-split basis.

2. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the
United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include
all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements. The December 31, 2003 balance sheet was derived
from audited financial statements, but does not include all the disclosures required by accounting principles generally accepted in the United States. However, we believe that the disclosures are
adequate to make the information presented not misleading. In our opinion, all the adjustments (consisting of normal recurring adjustments) considered necessary for fair presentation have been
included. The results of operations for the three months ending March 31, 2004 are not necessarily indicative of the results that may be achieved for the full fiscal year or for any future
period. The condensed consolidated financial statements included herein should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's annual
report on Form 10-K for the year ended December 31, 2003.

4. Accounting for Stock-Based Compensation

We account for employee stock-based compensation under APB 25. The following table summarizes relevant information as to the reported results under our intrinsic
value method of accounting for stock awards, with supplemental information as if the fair value recognition provision of SFAS 123 had been applied for the quarters ended March 31, 2004
and March 31, 2003 (in thousands, except per share data). All such information is reported in post reverse stock split values:

As
required, the pro forma disclosures above include options granted since January 1, 1995. Consequently, the effects of applying SFAS 123 for providing pro forma
disclosures may not be representative of the effects on reported operating results for future years until all options outstanding are included in the pro forma disclosures. For purposes of pro forma
disclosures, the estimated fair value of stock-based compensation plans and other options are amortized to expense primarily over the vesting period.

5. Net Loss Per Share

We report two separate earnings per share ("EPS") numbers, basic EPS and diluted EPS. Basic net loss per share is computed by dividing net loss attributable to
common stockholders for the period by the weighted average number of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss attributable to common
stockholders by the weighted average number of common shares and common stock equivalents outstanding for the period. Our common stock equivalents include all common stock issuable upon conversion of
convertible preferred stock and the exercise of outstanding options and warrants. The aggregate number of common stock equivalents excluded from the loss per share calculation for the three-month
periods ended March 31, 2004 and 2003 are 2,609,715 and 404,652, respectively. Our common stock equivalents are not included in the diluted loss per share for the three-month periods ended
March 31, 2004 and 2003, as they are antidilutive.

6. Commitments and Contingencies

We are subject to legal proceedings and claims that arise in the ordinary course of business. We do not believe that the outcome of those matters, if any, will
have a material adverse affect on our consolidated financial position, operating results or cash flows. However, there can be no assurance such legal proceedings will not have a material impact.

During
the quarter, we successfully renegotiated our lease agreement for our headquarters in Richardson, Texas, which decreased the amount of square feet we lease and extended the lease
term for an additional five years. In accordance with the new lease agreement, our Richardson, Texas headquarters will be located in the same building. However, we will reduce the amount of space that
we lease from approximately 95,000 square feet to approximately 30,000 square feet of floor space and the term of our new lease will expire in February 2010.

7. Preferred Stock Private Placement

On March 25, 2004, we completed a $5.0 million private placement of 5% Convertible Preferred Stock and warrants. In the private placement, we sold
1,000,000 shares of preferred stock at a price of $5.00 per share for gross proceeds of $5.0 million, less $275,000 of issuance costs. The preferred shares may be immediately converted into
1,590,331 shares of common stock at an initial conversion price of $3.144 per share.

The
5% dividends related to the preferred stock are paid semi-annually on the last business day in March and September of each year, beginning with September 2004.
Preferred stockholders vote together with common stockholders on an as converted to common stock basis. Based on the conversion rate of the preferred stock, holders of preferred stock will receive
1.5903 votes per share and rounded to the nearest whole number. The liquidation preference for the preferred stock is an amount equal to $5.00 per share plus any accrued and unpaid dividends. Holders
of preferred stock have liquidation preference rights over common stock holders.

Included
in this transaction were warrants to purchase 556,619 shares of common stock at an exercise price of $3.144 per share. In connection with the closing of this private placement,
we issued warrants to purchase 64,408 shares of our common stock at an exercise price of $3.144 per share to our financial advisor for assistance with the private placement. These 621,027 shares from
warrants were valued at $1.2 million using the Black-Scholes model and have been treated as a discount to the Preferred Stock and were recorded as an increase in additional paid in capital. The
issuance of the warrants resulted in a beneficial conversion feature to the Preferred Stock valued at $0.9 million. In accordance with EITF 98-5, the beneficial conversion feature
was fully amortized in the first quarter of 2004, as the preferred stock does not have a stated maturity and is immediately convertible into common stock. This beneficial conversion feature is added
to the net loss to arrive at the net loss attributed to common stockholders.

The
Preferred Stock was recorded as the net of the financing proceeds of $5.0 million less $275,000 issuance costs and the fair value of the warrants issued in conjunction with
the Preferred Stock of $1.2 million.

We
have the right to redeem any or all of the outstanding preferred stock at a price of $5.00 per share plus accrued dividends at any time after September 25, 2004 if certain
conditions are met.

this report are made in reliance on the Private Securities Litigation Reform Act of 1995. The section below entitled "Factors That May Affect Future Results of Operations" sets forth and incorporates
by reference certain factors that could cause actual future results of the company to differ materially from these statements.

Critical Accounting Policies and Estimates

Management's discussion and analysis of financial condition and results of operations are based upon our condensed consolidated financial statements, which have
been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect
the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including
those related to product returns, bad debts, inventories, income taxes, warranty obligations, restructuring, maintenance contracts and contingencies. We base our estimates on historical experience and
on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities
that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

We
believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our condensed consolidated financial statements.

---



Revenue Recognition

We generally recognize product revenue upon shipment of product. We accrue for estimated warranty costs and sales returns at the time of shipment based on our
experience. Revenue from maintenance contracts is deferred and recognized over the contractual period the services are performed, generally one year. There is a risk that technical issues on new
products could result in unexpected warranty costs and returns. However, as we migrate to more of a software-based business model, the warranty costs should continue to decline. To the extent that
they do decline, our warranty reserve from current sales will decrease. To the extent that our warranty costs exceed our expectations, we will increase our warranty reserve to compensate for the
additional expense expected to be incurred. We review these estimate periodically and determine the appropriate reserve percentage. However, to date, warranty costs and sales returns have not been
material. Historically, our estimates for these items have not differed materially from actual results. We believe that our revenue recognition policy does not include significant or subjective
estimates.

We
recognize software revenue from the licensing of our software products in accordance with Statement of Position ("SOP") No. 97-2 "Software Revenue Recognition",
SOP 98-9 "Modification of 97-2, Software Revenue Recognition, with respect to certain transactions" and Staff Accounting Bulletin ("SAB") No. 104, "Revenue
Recognition" whereby revenue from the licensing of our products is not recognized until all four of the following have been met: i) execution of a written agreement; ii) delivery of the
product has occurred; iii) the fee is fixed and determinable; and iv) collectibility is probable. Bundled hardware and perpetual software product sales are recognized at time of
delivery, as our licenses are not sold on a subscription basis. In the case of multiple product and service sales, we perform a Vendor Specific Objective Evidence analysis to appropriately determine
the amount of revenue derived from each deliverable. If our license strategy changes and we begin to offer licenses on a subscription basis, we would perform this analysis in a similar manner. Under
these circumstances, the revenue related to the license would be recognized ratably over the subscription period. Market values are easily obtained for all of our product offerings, as we have
historical sales information on our product offerings. We defer and recognize maintenance and support revenue over the term of the contract period, which is generally one year.

We
have signed distribution agreements with distributors in the United States, Europe and Asia. In general, these relationships are non-exclusive. Distributors typically
maintain an inventory of our products. Under these agreements, we provide certain protection to the distributors for their inventory of our products for price reductions as well as products that are
slow moving or have been discontinued by us. Historically, returns from our distributors and charges related to price reductions on inventory held by distributors have not been material. Recognition
of sales to distributors and related gross profits are deferred until the distributors resell the merchandise. However, since we have legally sold the inventory to the distributor and we no longer
have care, custody or control over the inventory, we recognize the trade accounts receivable and reduce inventory related to the sale at the time of shipment to the distributor. Revenue, offset by
deferred cost of sales, is included in deferred revenue in the accompanying financial statements. Since the net balance in Deferred Revenue represents the sales price less the cost of the product
maintained by the distributors, the deferred costs of these products are included in our obsolescence and slow-moving analysis and are written down according to their current value. This
transaction, effectively recognizes expense for the write-down, if any, and increases the net liability in the deferred revenue account.

We
generally recognize service revenue upon delivery of the contracted service. Service revenue, primarily including maintenance, training and installation are recognized upon delivery
of the service and typically are unrelated to product sales. These services are not essential to the functionality of the delivered product. To date, training and installation revenue has not been
material.

11

---



Allowance for Doubtful Accounts and Returns

Trade accounts receivable are stated at the amount we expect to collect. We maintain allowances for doubtful accounts for estimated losses resulting from the
inability of our customers to make required payments. Management considers the following factors when determining the collectibility of specific customer accounts: customer credit-worthiness, past
transaction history with the customer, current economic industry trends, and changes in customer payment terms. If the financial condition of our customers were to deteriorate, adversely affecting
their ability to make payments, additional allowances would be required. Based on management's assessment, we provide for estimated uncollectible amounts through a charge to earnings and a credit to a
valuation allowance. Balances that remain outstanding after we have used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable.
Historically, our estimates for sales returns and doubtful accounts have not materially differed from actual results.

Inventory

We write down our inventory for estimated obsolescence or unmarketable inventory equal to the difference between the cost of inventory and the estimated market
value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be
required. Historically, our estimates for inventory obsolescence have not differed materially from actual results.

Net Revenues.Net revenues for the quarter ended March 31, 2003 decreased 14.2% to $1.3 million compared to
$1.5 million for the same period of 2003 as revenues from our first generation security products decreased. Product revenue remained constant at $0.9 million when compared to the same
period in 2003. Customer support and maintenance revenue decreased 38.0% from $0.6 million in 2003 to $0.4 million in 2004 due to the expiration of maintenance contracts on some of our
legacy products. Total revenues (including maintenance and support) from our SecureNet product line increased slightly over the same period in 2003 from $1.1 million to $1.2 million in
2004. Our first generation product sales, including PDS and SecureCom decreased from the same period in 2003 from $0.4 million to $0.1 million in 2004. In addition, continued sluggish
economic conditions and delayed customer orders contributed to the decline in revenues.

Export Revenues.Export revenues for the quarter ended March 31, 2004 decreased to $0.4 million compared to
$0.8 million for the same period of 2003 as revenues from our PDS security appliance family decreased and we focused more of our resources domestically.

Concentration of Revenues.Revenues from Concurrent Technologies Corporation were 20.0% of revenues for the quarter ended
March 31, 2004, compared to 0.0% for the same period of 2003. Revenues from Expedia Inc. were 11.5% of revenues for the quarter ended March 31, 2004, compared to 0.0% for the same
period of 2003. Revenues from the U.K. Government were 1.5% of total revenues for the quarter ended March 31, 2004, compared to 11.4% for the same period of 2003. We expect the concentration of
revenues to continue with various customers, but that the particular customers will vary depending upon the timing of certain revenues in future quarters.

Gross Profit.Gross profit was $0.6 million or 49.7% of net revenues for the quarter ended March 31, 2004,
compared to $0.5 million or 32.0% of net revenues for the quarter ended March 31, 2003. Gross profit margins as a percentage of net revenues increased from the same period in the prior
year due to a continued shift in product mix, which resulted in an increase as a percentage of revenues of our more profitable SecureNet product line. Gross profit on product revenues increased from
4.4% in 2003 to 42.0% in 2004 due to the transition to our more profitable software-based products. Gross profit on customer support and maintenance revenue decreased from 74.1% in 2003 to 69.2% in
2004, as more repair costs were incurred during the quarter.

Gross
profit as a percentage of net revenues is impacted by several factors, including shifts in product mix, changes in channels of distribution, revenues volume, fluctuations in
third-party assembly costs, pricing strategies, and fluctuations in revenues of integrated third-party products.

Sales and Marketing.Sales and marketing expenses decreased to $1.0 million for the quarter ended March 31,
2004, compared to $1.9 million for the quarter ended March 31, 2003, primarily due to the reorganization of our sales and marketing departments, including a reduction in headcount, and
other cost reduction initiatives. We expect to continue to realize the impact of our cost reduction initiatives throughout 2004. Sales and marketing expenses may vary as a percentage of net sales in
the future. However, we believe that these costs will remain constant through the end of the year.

Research and Development.Research and development expenses decreased to $0.6 million for the quarter ended
March 31, 2004, compared to $0.9 million for the quarter ended March 31, 2003. Research and development costs are expensed in the period incurred. Research and development
expenses decreased in the quarter ended March 31, 2004, compared to the same period in 2003 as we focused more of our development efforts on our core security products, SecureNet and our
Information Compliance products, while reducing efforts on our other security products. Research and development expenses may vary as a percentage of net sales in the future.

14

---



General and Administrative.General and administrative expenses decreased to $0.3 million for the quarter ended
March 31, 2004, compared to $0.4 million for the quarter ended March 31, 2003, primarily due to the restructuring done in 2003, including a reduction in headcount, and other cost
reduction initiatives. It is expected that general and administrative expenses will remain relatively constant throughout the remainder of the year. General and administrative expense may vary as a
percentage of net sales in the future.

Severance Costs.Severance costs of $0.1 million for the three-month period ended March 31, 2004 consists
primarily of severance payments made after year-end as a result of reductions in force. All severance obligations were paid prior to March 31, 2004, and we were not receiving
further benefit from the severed individuals after March 31, 2004. Severance costs of $0.1 million for the three-month period ended March 31, 2003 consisted of reductions in force
made during that period.

Interest.Net interest income decreased to $18 thousand for the quarter ended March 31, 2004 compared to
$61 thousand for the same period in 2003. The slight decrease in interest income was primarily due to the reduced overall cash balances resulting from operating losses. Net interest income may
vary in the future based on our cash flow and rate of return on investments.

Liquidity and Capital Resources

Our principal source of liquidity at March 31, 2004 is approximately $5.8 million of cash and cash equivalents and $0.5 million of
short-term investments. As of March 31, 2004 working capital was $5.9 million compared to $8.3 million as of March 31, 2003.

On
March 25, 2004, we completed a $5.0 million private placement of 5% Convertible Preferred Stock and warrants. In the private placement, the Company sold 1,000,000 shares
of preferred stock at a price of $5.00 per share, which may be converted into 1,590,331 shares of common stock at an initial conversion price of $3.144 per share, and warrants to purchase 556,615
shares of common stock at an exercise price of $3.144 per share. In connection with the closing of this private placement, we issued warrants to purchase 64,409 shares of our common stock at an
exercise price of $3.144 per share to our financial advisor for the private placement.

Cash
used in operations for the three months ended March 31, 2004 was $1.1 million, primarily due to an operating loss of $1.3 million, an increase in inventories of
$0.2 million and a decrease in accounts payable and accrued expenses of $0.3 million, which is offset by depreciation expense of $0.1 million and a decrease in accounts receivable
of $0.5 million and an increase in deferred revenue of $0.1 million and a decrease in other assets of $0.0 million, compared to cash used in operations of $2.4 million for
the three months ended March 31, 2003, primarily due to an operating loss from continuing operations of $2.8 million, which is offset by depreciation expense and a decrease in accounts
receivable. Future fluctuations in inventory balances, accounts receivable and accounts payable will be dependent upon several factors, including, but not limited to, quarterly sales, our strategy in
building inventory in advance of receiving orders from customers, and the accuracy of our forecasts of product demand and component requirements.

Cash
provided in investing activities in the three months ended March 31, 2004 was $1.2 million, which consisted primarily of the net maturity of short-term
investments, compared to cash provided by investing activities of $0.5 million for the three months ended March 31, 2003, which also consisted primarily of the maturity of
short-term investments.

Cash
provided by financing activities in the three months ended March 31, 2004 was $4.7 million, consisting of net financing proceeds from a private placement and the
exercise of employee stock options, compared to $0.0 million during the three months ended March 31, 2003.

At
March 31, 2004, the Company did not have any material commitments for capital expenditures.

15

---



During
the three months ended March 31, 2004, the Company funded its operations through the use of cash and cash equivalents.

Although
we believe we have sufficient cash resources to finance our operations and expected capital expenditures for the next twelve months, the sufficiency of our cash resources may
depend to a certain extent on general economic, financial, competitive or other factors beyond our control. Moreover, despite actions to reduce our costs and improve our profitability, we expect our
operating losses and net operating cash outflows to continue at least through the first half of 2004. As a result, we may not be able to achieve the revenue and gross margin objectives necessary to
achieve positive cash flow or profitability without obtaining additional financing. We do not currently have any arrangements for financing, and we may not be able to secure additional debt or equity
financing on terms acceptable to us, or at all, at the time when we need such funding. If our business does not generate sufficient cash flow from operations and sufficient future financings are not
available, we may not be able to operate or grow our business, pay our expenses when due or fund our other liquidity needs.

We
intend to explore the possible acquisitions of businesses, products and technologies that are complementary to our existing business. We are continuing to identify and prioritize
additional security technologies which we may wish to develop, either internally or through the licensing or acquisition of products from third parties. While we engage from time to time in
discussions with respect to potential acquisitions, there can be no assurances that any such acquisitions will be made or that we will be able to successfully integrate any acquired business. In order
to finance such acquisitions and working capital it may be necessary for us to raise additional funds through public or private financings. Any equity or debt financings, if available at all, may be
on terms, which are not favorable to us and, in the case of equity financings, may result in dilution to our stockholders.

Factors That May Affect Future Results of Operations

Numerous factors may affect our business and future results of operations. These factors include, but are not limited to, current economic and market conditions,
the effect of military actions on government and corporate spending on information security products, spending patterns of, and appropriations to, U.S. government departments, technological changes,
competition and market acceptance, acquisitions, product transitions, timing of orders, manufacturing and suppliers, reliance on outsourcing vendors and other partners, intellectual property and
licenses, third-party products, dependence on government customers, international operations, intellectual property issues, liquidity and cash resources and effects of restructuring plans and cost
reductions. The discussion below addresses some of these and other factors. For a more thorough discussion of these and other factors that may affect our business and future results, see the
discussion under the caption "Factors That May Affect Future Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2003.

If we fail to respond to rapid technological changes in the network security industry, we may lose customers or our products may become obsolete.

16

---



The
network security industry is characterized by frequent product introductions, rapidly changing technology and continued evolution of new industry standards. We must also introduce
upgrades to our products rapidly in response to customer needs such as new computer viruses or other novel external attacks on computer networks. In addition, the nature of the network security
industry requires our products to be compatible and interoperable with numerous security products, networking products, workstation and personal computer architectures and computer and network
operating systems offered by various vendors, including our competitors. As a result, our success depends upon our ability to develop and introduce in a timely manner new products and enhancements to
our existing products that meet changing customer requirements and evolving industry standards. The development of technologically advanced network security products is a complex and uncertain process
requiring high levels of innovation, rapid response and accurate anticipation of technological and market trends. We cannot assure you that we will be able to identify, develop, manufacture, market or
support new or enhanced products successfully in a timely manner. Further, we or our competitors may introduce new products or product enhancements that shorten the life cycle of our existing products
or cause our existing products to become obsolete.

Our revenues have declined from $16.7 million in 2001 to $6.5 million in 2003 in connection with a shift to sales of our newer product lines. If our network
intrusion detection and regulated information compliance system products do not achieve market acceptance, our revenues will suffer.

Over
the past three years, we have transitioned our sales strategy from our lower margin SecureCom and PDS security appliance products to the development and sales of our higher margin
SecureNet network intrusion detection products. During this transition, sales of our new products were not enough to counteract the loss in sales associated with our older products. As a result, our
net revenues have declined from approximately $16.7 million in 2001, to approximately $7.8 million in 2002 and approximately $6.5 million in 2003. In addition, our revenues for
the first quarter of 2004 are $1.3 million as compared to $1.5 million for the same period in 2003.

Our
new network security products and regulated information compliance systems have only been in the market place for a limited period of time and may have longer sales cycles than our
previous products. Although response to our products has been positive, we have not yet received broad market acceptance. We cannot assure you that our present or future products will achieve market
acceptance on a sustained basis.

In
order to achieve market acceptance and achieve future revenue growth, we must introduce complementary security products, incorporate new technologies into our existing product lines
and design, develop and successfully commercialize higher performance products in a timely manner. We cannot assure you that we will be able to offer new or complementary products that gain market
acceptance quickly enough to avoid decreased revenues during current or future product introductions or transitions.

We resemble a developmental stage company and our business strategy may not be successful.

From
our founding in 1983 until 2000, we derived substantially all of our revenue from the design, manufacture and sale of local area networking equipment. In order to permit us to focus
our resources solely on developing and marketing our network security products, on April 17, 2000, we announced our plans to sell our local area networking assets and related networking
divisions.

17

---



As
a result of these sales, we now depend exclusively on revenues generated from the sale of our networks security products, which have received limited market acceptance. Moreover, we
have only recently introduced our regulated information compliance systems, and the market for these products has only begun to emerge. Consequently, we resemble a developmental stage company and will
face the following inherent risks and uncertainties:



Our
business strategy may not successfully address these risks. If we fail to recognize significant revenues from the sales of our network security products and regulated information
compliance systems, our business, financial condition and operating results would be materially adversely affected.

We had a net loss of $1.3 million and an accumulated deficit of $45.5 million as of the quarter ending March 31, 2004. As a result, we must generate
substantially greater revenues from sales in order to achieve profitability.

We
have incurred significant operating losses and are uncertain about our future operating results. For the quarter ended March 31, 2004, we incurred a net loss of
$1.3 million and had an accumulated deficit of approximately $45.5 million at March 31, 2004. In addition, our revenues have declined from $16.7 million in 2001, to
$7.8 million in 2002, and $6.5 million in 2003. We need to generate and sustain substantially greater revenues from the sales of our products if we are to achieve profitability. If we
are unable to achieve these greater revenues, our losses will continue indefinitely, and we may never achieve or sustain profitability or generate positive cash flow.

We face intense competition from both start-up and established companies that may have significant advantages over us and our products.

The
market for network security solutions is intensely competitive. There are numerous companies competing with us in various segments of the data security markets, and their products
may have advantages over our products in areas such as conformity to existing and emerging industry standards, interoperability with networking and other security products, management and security
capabilities, performance, price, ease of use, scalability, reliability, flexibility, product features and technical support.

Our
principle competitors in the network intrusion and detection market include Internet Security Systems, Inc., Cisco Systems, Inc., Symantec, Inc., Netscreen
Technologies, Inc., Tipping Point Technologies Inc. and NFR Security, Inc. The market for regulated information compliance systems is relatively new. Our competitors in this
market include a number of start up companies that have entered the market in the last two years. However, as this market develops, we expect increased competition from both start up and established
companies. Our current and potential competitors may have one or more of the following significant advantages over us:



18

---





Although
we believe that our focus on network perimeters with market leading VPN/firewall control technology and network intrusion detection visibility technology that reduce the total
cost of ownership provides us with an advantage with large organizations with complex security requirements, we cannot assure you that our products will achieve market acceptance or that we will be
able to compete successfully with our existing or new competitors.

Military actions may disrupt our business by reducing spending our products, increasing our costs and affecting our international operations.

United
States military actions or other events occurring in response to or in connection with them, including future terrorist attacks, actual conflicts involving the United States or
its allies or military or trade disruptions could impact our operations by:



Should
these events occur, our business, operating results and financial condition could be materially and adversely affected.

Our products can have long sales and implementation cycles, which may result in us incurring substantial expenses before realizing any associated
revenues.

The
sale and implementation of our products to large companies and government agencies typically involves a lengthy education process and a significant technical evaluation and
commitment of capital and other resources. This process is also subject to the risk of delays associated with customers' internal budgeting and other procedures for approving capital expenditures,
deploying new technologies within their networks and testing and accepting new technologies that affect key operations. As a result, sales and implementation cycles for our products can be lengthy,
and we may expend significant time and resources before we receive any revenues from a customer or potential customer. Our quarterly and annual operating results could be materially harmed if orders
forecasted for a specific customer for a particular period are not realized.

Our cash, cash equivalents, and investments declined from $10.7 million to $2.7 million during 2003. As a result of our expected continuing net cash outflows, we
may not have sufficient cash to operate our business.

As
of December 31, 2003, we had cash, cash equivalents and investments in the amount of approximately $2.7 million, down from approximately $10.7 million as of
December 31, 2002. Although we believe the additional $5.0 million in gross proceeds we received in connection with a private placement of preferred stock and warrants we completed on
March 25, 2004 will provide us with sufficient cash resources to finance our operations for the next twelve months, the sufficiency of our cash resources may depend to a certain extent on
general economic, financial, competitive or other factors beyond our control. Moreover, despite our actions to reduce costs and improve profitability, we expect our net operating losses and net
operating cash outflows to continue through at least the first half of 2004. We do not currently have any further arrangements for financing, and we may not be able to secure additional debt or equity
financing on terms that are acceptable to us, or at all, at the time when we need this financing. If our business does not generate sufficient cash flow from operations and sufficient financing
resources are not available, we may not be able to operate or grow our business, pay our expenses when due or fund our other liquidity needs.

Our failure to realize the expected benefits of our recent restructuring efforts could adversely affect our operating results.

19

---



During
the first quarter of 2004, we continued a restructuring plan and cost reduction efforts, which resulted in $0.1 million in severance costs. Since we began restructuring in
2002, we have incurred approximately $0.8 million in restructuring charges, severance, and related expenses. The objective of our restructuring plan was to reduce our cost structure to a
sustainable level that is consistent with our current cash resources and the general economic climate. We have also implemented other strategic initiatives to strengthen our operations, such as
reductions in our work force and facilities and aligning our organization around our business objectives. Any further work force reductions could result in temporary reduced productivity of our
remaining employees. Additionally, our customers and prospects may delay or forgo purchasing our products due to a perceived uncertainty caused by our restructuring and other changes. Failure to
achieve the desired results of our initiatives could seriously harm our business, results of operations and financial condition.

Consolidation in the network security industry may limit market acceptance of our products.

Several
of our competitors have acquired security companies with complementary technologies in the past, and we expect consolidation in the network security industry to continue in the
future. These acquisitions may permit our competitors to accelerate the development and commercialization of broader product lines and more comprehensive solutions than we currently offer.
Acquisitions of vendors or other companies with which we have a strategic relationship by our competitors may limit our access to commercially significant technologies. Further, business combinations
in the network security industry are creating companies with larger market share, customer bases, sales forces, product offerings and technology and marketing expertise, which may make it more
difficult for us to compete.

Sales to government agencies accounted for 34.5% of our revenues the quarter ended March 31, 2004 and 17% of our revenues for the year ended December 31, 2003.
Sales to government customers involve unique risks, which could adversely impact our revenues.

We
derived 34.5% of our revenues from sales to various U.S. government entities for the quarter ended March 31, 2004, and 17.0% of our revenues from these sales for the year ended
December 31, 2003. We expect to continue to derive a substantial portion of our revenues from U.S. government customers in the future. Sales to the government present risks in addition to those
involved in sales to commercial customers, including potential disruption due to appropriation and spending patterns and he government's right to cancel contracts and purchase orders for its
convenience. General political and economic conditions, which we cannot accurately predict, directly and indirectly may affect the quantity and allocation of expenditures by federal departments. In
addition, obtaining government contracts may involve long purchase and payment cycles, competitive bidding, qualification requirements, delays or changes in funding, budgetary constraints, political
agendas, extensive specification development and price negotiations and milestone requirements. Each government entity also maintains its own rules and regulations with which we must comply and which
can vary significantly among departments. As a result, cutbacks or re-allocations in the federal budget or losses of government sales due to other factors could have a material adverse
effect on our revenues and operating results.

We derived 32.5% of our revenues from international sales in the quarter ended March 31, 2004, and 31.4% of our revenues from these sales for the year ended
December 31, 2003. Our ability to sell our products internationally are subject to certain risks which could harm our business.

Sales
to foreign customers accounted for approximately 31.4% of our revenues for the year ended December 31, 2003, and 32.5% of our revenues for the quarter ended March 31,
2004. We expect sales to foreign customers to continue to represent a significant portion of our revenues in the future. Our international operations are subject to many inherent risks that may
adversely affect our business, financial condition and operating results, including:

Sales through indirect channels accounted for 38% of our revenues for the quarter ended March 31, 2004 and 57% of our revenue for the year ended December 31,
2003. Our revenues will suffer if we do not expand our sales through, or receive the anticipated benefits from our sales through, indirect sales channels.

We
derived 38% of our revenues for the quarter ended March 31, 2004, and 57% of our revenue for the year ended December 31, 2003 from sales through indirect sales channels,
such as distributors, value added resellers, system integrators, original equipment manufacturers and managed service providers. We believe we must expand our sales through these indirect channels in
order to increase our revenues. Although we are actively pursuing a strategy to increase the percentage of our revenues generated through these indirect sales channels, we cannot assure you that our
products will gain market acceptance in these indirect sales channels or that sales through these indirect sales channels will increase our revenues as expected. Further, many of our competitors are
also trying to sell their products through these indirect sales channels, which could result in lower prices and reduced profit margins for sales of our products.

We must adequately protect our intellectual property in order to prevent loss of valuable proprietary information.

We
rely on a combination of patent, copyright, trademark and trade secret laws, confidentiality procedures and non-disclosure agreements to protect our proprietary
technology. However, unauthorized parties may attempt to copy or reverse engineer aspects of our products or to obtain and use information that we regard as proprietary. Policing unauthorized use of
our products is difficult, and we cannot be certain that the steps we have taken will prevent misappropriation of our intellectual property. This is particularly true in foreign countries where the
laws may not protect proprietary rights to the same extent as the laws of the United States and may not provide us with an effective remedy against unauthorized use. If our protection of our
intellectual property proves to be inadequate or unenforceable, others may be able to use our proprietary developments without compensation to us, resulting in potential cost advantages to our
competitors.

We may incur substantial expenses defending ourselves against claims of infringement.

There
are numerous patents held by many companies relating to the design and manufacture of network security systems. Although we are not aware of any instances in which our products
violate the intellectual property rights of others or inappropriately use their technology, it is possible that third parties in the future may claim that our products infringe on their intellectual
property rights. Any claim, with or without merit, could consume our management's time, result in costly litigation, cause delays in sales or implementations of our products or require us to enter
into royalty or licensing agreements. Royalty and licensing agreements, if required and available, may be on terms unacceptable to us or detrimental to our business. Moreover, a successful claim of
product infringement against us or our failure or inability to license the infringed or similar technology on commercially reasonable terms could seriously harm our business.

Fluctuations in our quarterly revenues may cause the price of our common stock to decline.

Our
operating results have varied significantly from quarter to quarter in the past, and we expect our operating results to vary from quarter to quarter in the future due to a variety of
factors, many of which are outside of our control. Although our revenues are subject to fluctuation, significant portions of our expenses are not variable in the short term, and we cannot reduce them
quickly to respond to decreases in revenues. Therefore, if revenues are below our expectations, this shortfall is likely to adversely and disproportionately affect our operating results. Accordingly
we may not attain positive operating margins in future quarters. Any of these factors could cause our operating results to be below the expectations of securities analysts and investors, which likely
would negatively affect the price of our common stock.

The price of our common stock has been volatile in the past and may continue to be volatile in the future due factors outside of our control.

The
market price of our common stock has been highly volatile in the past and may continue to be volatile in the future. For example, since June 1, 2003, the market price of our
common stock on The Nasdaq SmallCap Market has fluctuated between $1.40 and $5.54 per share. The market price of our common stock may fluctuate significantly in response to a number of factors, many
of which are outside our control, including:



Our recent reductions in our work force may make it more difficult for us to attract and retain the personnel necessary to successfully operate our
business.

We
rely upon the continued service of a relatively small number of key technical, sales and senior management personnel. Our future success depends on retaining our key employees and our
continuing ability to attract, train and retain other highly qualified technical, sales and managerial personnel. We have employment agreements with relatively few of our key technical, sales and
senior management personnel. As a result, our employees could resign with little or no prior notice. We may not be able to attract, assimilate or retain other highly qualified technical, sales and
managerial personnel in the future, especially given our recent reductions in force. The loss of any of our key technical, sales and senior management personnel or our inability to attract, train and
retain additional qualified personnel could seriously harm our business.

Certain rights of the holders of 5% convertible preferred stock may hinder our ability to raise additional financing.

22

---



We
cannot issue shares of capital stock with rights senior to those of our existing preferred or incur certain indebtedness without the approval of at least a majority of the holders of
our 5% convertible preferred stock. In addition, holders of the preferred stock who are not executive officers or directors have the right to purchase a pro rata portion of certain future issuances of
securities by us. The combination of these provisions could hinder or delay our ability to raise additional debt or equity financing.

You will experience substantial dilution upon the conversion of the shares of preferred stock and exercise of warrants that we issued in a private
placement.

On
March 25, 2004, we completed a $5,000,000 private placement in connection with which we issued 1,000,000 shares of our 5% Convertible Preferred Stock and warrants to acquire
556,619 shares of our common stock. The conversion price for the preferred stock and the exercise price of the warrants is $3.144 per share. We also issued our placement agent a warrant for 64,408
shares of our common stock at an exercise price of $3.144 per share. As a result, we expect the private placement to result in dilution to holders of our common stock upon conversion of the preferred
stock and exercise of the warrants of 2,221,358 shares of common stock, or an approximately 43% increase in the number of shares of our common stock outstanding.

The conversion of preferred stock or exercise of warrants we issued in the private placement may cause the price of our common stock to decline.

Upon
the effectiveness of the registration statement related to this prospectus, the holders of preferred stock and warrants we issued in the private placement will be able to freely
convert their shares of preferred stock and exercise their warrants and sell their underlying shares of common stock. For the four weeks ended on May 28, 2004, the average daily trading volume
of our common stock on The Nasdaq SmallCap Market was 15,725 shares. Consequently, if holders of preferred stock or warrants elect to convert their shares or exercise their warrants and sell a
material amount of their underlying shares of common stock on the open market, the increase in selling activity could cause a decline in the market price of our common stock. Furthermore, these sales,
or the potential for these sales, could encourage short sales, causing additional downward pressure on the market price of our common stock.

The percentage of our revenues attributable to sales of PDS products integrated with software of Check Point Software Technologies decreased from 29.1% in 2002 to 16.7% in 2003
and from 25.7% for the first quarter of 2003 to 4.6% for the first quarter of 2004. Because sales of our newer products may not offset the reduced sales of our PDS products, a change in our
relationship with Check Point could have a negative effect on our operating results.

Our
PDS family of security appliances, which are integrated with Check Point Software Technologies' market-leading VPN-1®/FireWall-1®
software, represented 4.6% of our revenues for the quarter ended March 31, 2004, and 16.7% of our revenues for the year ended December 31, 2003. These percentages are down from 25.7% of
our revenues for the quarter ended March 31, 2003, and 29.1% of our revenues for the year ended December 31, 2002. We expect the percentage of our sales attributable to our PDS products
to decline in the future; however, our reliance on newer product sales may not replace the anticipated decline in revenue from sales of our PDS products. Although we are a certified appliance partner
of Check Point and our PDS products have received Check Point certification, we have no long-term agreement or exclusive relationship with Check Point. As a result, the loss or significant
change in our relationship with Check Point, the failure of our PDS products to maintain or receive Check Point certification, the business failure of Check Point or its acquisition by or of one of
our competitors and the loss of market share of Check Point or market acceptance of its products could each have a material adverse effect on our business, financial condition and results of
operations.

Our acquisition of complementary products or businesses may adversely affect our financial condition.

We
have made acquisitions in the past, and, in the future, we may acquire or invest in additional companies, business units, product lines or technologies to accelerate the development
of products and sales channels complementary to our existing products and sales channels. Negotiation of potential acquisitions and integration of acquired products, technologies or businesses could
divert our management's time and resources. Future acquisitions could cause us to issue equity securities that would dilute your ownership of us, incur debt or contingent liabilities, amortize
intangible assets or write off in-process research and development, goodwill and other acquisition-related expenses that could seriously harm our financial condition and operating results.
Further, if we are not able to properly integrate acquired products, technologies or businesses with our existing products and operations, train, retain and motivate personnel from the acquired
business or combine potentially different corporate cultures, we may not receive the intended benefits of our acquisitions, which could adversely affect our business, operating results and financial
condition.

The payment of accrued dividends on our 5% convertible preferred stock may strain our cash resources.

Shares
of our 5% convertible preferred stock accrue cash dividends equal to $0.25 per share per annum. These dividends are payable in arrears on March 31 and September 30
of each year, commencing on September 30, 2004. Delaware law provides that we may only pay dividends out of our capital surplus or, if no surplus is available, out of our net profits for the
fiscal year the dividend is declared and/or the preceding fiscal year. We have not had net profits for the last two fiscal years, and as of March 31, 2004 our capital surplus, defined as the
amount by which our net assets exceed our stated capital, was approximately $2.7 million. Therefore, we have only limited resources to pay these dividends. In addition, the payment of these
dividends could strain our available cash resources, which could adversely affect our ability to operate or grow our business.

Compliance with export regulations may hinder our sales to foreign customers.

Certain
of our data security products incorporate encryption and other technology that may require clearance and export licenses from the U.S. Department of Commerce under United States
export regulations. Any inability to obtain these clearances or licenses or any foreign regulatory approvals, if required, on a timely basis could delay sales and have a material adverse effect on our
operating results.

Provisions of our charter documents and Delaware law may have anti-takeover effects.

Certain
provisions of our certificate of incorporation and bylaws, such as our ability to offer "blank check" preferred stock and the inability of our stockholders to act by written
consent, could make it more difficult for a third party to acquire us, even if doing so would be beneficial to our stockholders. We are also subject to the provisions of Section 203 of the
Delaware General Corporation Law, which restricts certain business combinations with interested stockholders and could inhibit a non-negotiated merger or other business combination.

Our management and larger stockholders exercise significant control over our company and may approve or take actions that may be adverse to your
interests.

As
of May 31, 2004, our executive officers, directors and 5% stockholders beneficially own approximately 38.5% of our voting power. As a result, these stockholders will be able to
exercise significant control over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, which could delay or prevent
someone from acquiring or merging with us. These stockholders may use their influence to approve or take actions that may be adverse to your interests.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Exchange.Revenue originating outside the U.S. in the quarters ended March 31, 2004 and 2003 was 32.5% and
51.6% of total revenues, respectively. International sales are made mostly from our foreign sales subsidiaries in the local countries and are typically denominated in U.S. dollars. These subsidiaries
incur most of their expenses in the local currency.

Our
international business is subject to risks typical of an international business, including, but not limited to: differing economic conditions, changes in political climate, differing
tax structures, other regulations and restrictions and foreign exchange rate volatility. Accordingly, our future results could be materially adversely affected by changes in these or other factors.
The effect of foreign exchange rate fluctuations on us in 2004 and 2003 was not material.

On
January 1, 2003, the Company elected to change the functional currency of its foreign operations to the United States dollar. This change in functional currency is supported by
the fact that all foreign operations are funded monthly in United States dollars and the majority of a revenue contracts are denominated in United States dollars. Under United States dollar functional
currency, the financial statements of foreign locations are remeasured from the recording currency to the United States dollar. The resulting remeasurement adjustment is recorded as foreign exchange
gain or loss in the statement of operations. There is no translation adjustment to the separate component of stockholders' equity or adjustment to comprehensive income. The effect of the change in
functional currency had no material impact on results of operations. The accumulation of prior years' translation adjustments remains on the balance sheet as a separate component of stockholders'
equity until part, or all, of the respective entities are disposed.

Interest Rates.We invest our cash in a variety of financial instruments, including bank time deposits, fixed rate
obligations of corporations, municipalities, and state and national governmental entities and agencies. These investments are denominated in U.S. dollars. Cash balances in foreign currencies overseas
are operating balances and are invested in short-term time deposits of the local operating bank.

Interest
income on our investments is carried in "Interest income, net". We account for our investment instruments in accordance with SFAS No. 115, "Accounting for Certain
Investments in Debt and Equity Securities". All of the cash equivalents and short-term investments are treated as available-for-sale under SFAS 115.

Investments
in fixed rate interest earning instruments carry a degree of interest rate risk. Fixed rate securities may have their fair market value adversely impacted due to a rise in
interest rates. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates or we may suffer losses in principal if forced to sell
securities, which have seen a decline in market value due to changes in interest rates. Our investment securities are held for purposes other than trading. The weighted-average of the stated coupon
interest rate on investment securities at March 31, 2004 was 5.83%. Due to the amortization of premiums and discounts paid, the actual rate of return will vary from the weighted-average of the
stated coupon interest rate. The fair value of investments held at March 31, 2004 approximated amortized cost.

Item 4. CONTROLS AND PROCEDURES

We have carried out an evaluation, under the supervision and the participation of our management, including our Chief Executive Officer and Chief Financial
Officer, of the effectiveness of our disclosure controls and procedures as of March 31, 2004, pursuant to Rule 13a-15(b) under the Exchange Act. Based upon that evaluation,
our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective in ensuring that information required to be disclosed is recorded,
processed, summarized and reported in a timely manner.

We
have carried out an evaluation, under the supervision and participation of our management, including our Chief Executive Officer and Chief Financial Officer, of any changes in our
internal controls over financial reporting that occurred during the quarterly period ended March 31, 2004, and our Chief Executive Officer and Chief Financial Officer have concluded that there
was no change during the quarterly period ended March 31, 2004 that has materially affected or is reasonably expected to materially affect our internal control over financial reporting.

PART IIOTHER INFORMATION

Item 1. LEGAL PROCEEDINGS

We are subject to legal proceedings and claims that arise in the ordinary course of business. We do not believe that the outcome of those matters will have a
material adverse affect on our consolidated financial position, operating results or cash flows. However, there can be no assurance such legal proceedings will not have a material impact.

Item 2. CHANGES IN SECURITIES, USE OF PROCEEDS AND ISSUER PURCHASES OF EQUITY SECURITIES

(a)   On
March 18, 2004, we filed an amendment to our certificate of incorporation to effect a four-for-one (4:1) reverse stock split which
became effective on March 29, 2004. As a result of the split, every four (4) shares of our common stock outstanding as of the close of business on March 26, 2004, were combined
into one (1) share of common stock on March 29, 2004. We did not issue any fractional shares in connection with the reverse stock split. Instead all fractional shares were rounded up to
the nearest whole share. We did not change the authorized number of shares of our common stock, the par value of our common stock, the rights of holders of common stock to one (1) vote per
share held, or any of the other rights, preferences or privileges of our common stock in connection with the reverse split.

(b)   On
March 25, 2004, we filed a certificate of designation to create our 5% convertible preferred stock, which consists of 1,000,000 authorized shares and has the
rights, preferences and privileges summarized below.

Dividends.Holders of preferred stock are entitled to a 5% per annum dividend per share. The dividend accrues and is payable
in cash semi-annually on the last business day of March and September. Accrued but unpaid dividends are also payable upon the conversion or redemption of the shares of preferred stock and
upon a liquidation event. If we are in default in the payment of the dividends on the preferred stock, we cannot declare or pay any dividends on shares of common stock.

Voting Rights.Holders of preferred stock vote together with shares of common stock on an as converted to common stock basis.
Based on the conversion rate of the preferred stock, holders of shares of preferred stock will receive 1.5903 votes for each share. After aggregating all voting rights of a particular holder, any
fractional votes are rounded to the nearest whole number. As a result, a holder of 100 shares of preferred stock would be entitled to 159 votes on any matters submitted to our stockholders for
approval. Based on the 1,000,000 shares of preferred stock outstanding and the 5,166,312 shares of common stock outstanding as of April 30, 2004, the preferred stock constitutes approximately
23.5% of our outstanding voting power.

In
addition, as long as any shares of preferred stock are outstanding, we cannot take any of the following actions without the separate class vote or written consent of a majority of the
then outstanding shares of preferred stock:



27

---





Conversion.The preferred stock, which is comprised of an aggregate of 1,000,000 authorized shares, is convertible, at the
option of the holders, into shares of our common stock at an initial conversion price of $3.144 per share. Based on the original purchase price of $5.00 per share, each share of preferred stock is
initially convertible into 1.5903 shares of our common stock. The preferred stock contains adjustment provisions upon the occurrence of stock splits, stock dividends, combinations, reclassifications
or similar events of our capital stock.

A
holder of preferred stock cannot convert shares of preferred stock into shares of our common stock if that holder would beneficially own greater than 9.9% of our issued and outstanding
shares of common stock, as determined in accordance with Section 13(d) of the Exchange Act, upon conversion of the preferred stock.

Redemption.We have the right to redeem any or all of the outstanding shares of preferred stock at a price of $5.00 per share
plus any accrued but unpaid dividends at any time after September 25, 2004 if the following conditions are met:



Rank; Liquidation Preference.The holders of preferred stock rank prior to the holders of our common stock and, unless
otherwise consented to by the holders of preferred stock, prior to all other classes of capital stock currently outstanding, or that we may establish, with respect to the distribution of our assets
upon a bankruptcy, liquidation or other similar event. The liquidation preference for the preferred stock is an amount equal to $5.00 per share plus any accrued and unpaid dividends.

(c)   On
March 25, 2004, we completed a private placement under Rule 506 of Regulation D in which six institutional investors and three individual
accredited investors, including G. Ward Paxton, our Chairman, President and Chief Executive Officer, and James F. Gero, a member of our Board of Directors, pursuant to which the investors paid us an
aggregate of $5,000,000 in cash in consideration for (1) 1,000,000 shares of our 5% convertible preferred stock convertible into shares of our common stock at an initial conversion price of
$3.144 per share and (2) warrants to purchase up to 556,619 shares of our common stock at an initial exercise price of $3.144 per share. In addition, we issued Black Point
Partners, Inc., our financial advisor in the private placement, a warrant to purchase 64,408 shares of our common stock at an exercise price of $3.144 per share. The shares of preferred stock
currently are convertible into 1,590,331 shares of our common stock. The conversion price of the preferred stock and the exercise price of the warrants are subject to adjustments for stock dividends,
splits, combinations, reclassifications and similar transactions. The investors in the private placement cannot convert shares of preferred stock into shares of our common stock or exercise their
warrants if that investor would beneficially own greater than 9.9% of our issued and outstanding shares of common stock, as determined in accordance with Section 13(d) of the Exchange Act,
after the conversion or exercise.

Item 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

At a special meeting held on March 18, 2004, our stockholders voted on a proposal to amend our certificate of incorporation to effect a
four-for-one (4:1) reverse stock split of our common stock as follows:
