USE OF PROCEEDS

      We estimate that the net proceeds from the sale of the 1,000,000 units that we are selling in this offering will be approximately $8,200,000, or $9,527,500 if the representative exercises its over-allotment option in full, based on an assumed public offering price of $10.00 per unit, and after deducting the underwriting discount, expense allowance, and estimated offering expenses of $650,000 payable by us.

      We expect to allocate the net proceeds of this offering as follows:

      The debt we intend to repay includes:

	•	a $1,500,000 note at an interest rate of bank prime, which was 9.5% at December  31, 2000, plus 1%, payable to a director;
	•	a $500,000 note at an interest rate of 18% payable to a private investor;
	•	a $189,980 note at an interest rate of 10% payable to a third-party vendor;
	•	a $99,974 note at an interest rate of 10% payable to our chairman;
	•	a remaining balance of $94,000 on a note at an interest rate of 11% payable to a private investor; and
	•	approximately $300,000 of accrued but unpaid interest on notes to our stockholders, including our chairman and a director.

Further, if the representative exercises its over-allotment option in full, we will repay the principal on other outstanding stockholder notes of approximately $1.3 million.

      Payment of accrued expenses and payables includes deferred employee expense reimbursement, accumulated interest, past due trade payables, and other miscellaneous accrued expenses.

      Pending application of the net proceeds, we intend to invest the net proceeds in interest-bearing, investment grade securities.

      The foregoing discussion is merely an estimate based on our current business plan. Our actual expenditures may vary depending upon circumstances not yet known, such as the time actually required to reach a positive cash flow or to successfully expand the market for our products.

DIVIDEND POLICY

      We have never declared or paid any cash dividends on our shares of common stock and do not anticipate paying any cash dividends in the foreseeable future. Currently, we intend to retain any future earnings for use in the operation and expansion of our business. Any future decision to pay cash dividends will be at the discretion of our board of directors and will depend upon our financial condition, results of operations, capital requirements and other factors our board of directors may deem relevant.

11

CAPITALIZATION

      The following table sets forth our capitalization at December 31, 2000 on an actual basis and on a pro forma basis, after giving effect to our reincorporation in Delaware, our related 1-for-6 reverse stock split, and the sale of 1,000,000 units offered hereby at an estimated price of $10.00 per unit and the initial application of the estimated net proceeds therefrom. This table should be read in conjunction with, and is qualified by, the financial statements and notes thereto included elsewhere in this prospectus.

12

DILUTION

      If you invest in our units, your interest will be diluted to the extent of the difference between the public offering price per share of our common stock and the as adjusted net tangible book value per share of our common stock after this offering. For purposes of the dilution computation and the following tables, we have allocated the full purchase price of a unit to the share of common stock included in the unit and nothing to the warrant included in the unit. As of December 31, 2000, our net tangible book value was a negative $3,559,855, or a deficiency of $2.36 per share of common stock. Net tangible book value per share represents the amount of our total tangible assets reduced by the amount of our total liabilities, divided by the total number of shares of common stock outstanding. Dilution in net tangible book value per share represents the difference between the amount per share paid by the purchasers of our units in this offering and the net tangible book value per share of our common stock immediately afterwards. Without taking into effect any changes in the net tangible book value after December 31, 2000, other than to give effect to the sale of 1,000,000 units in this offering at the assumed initial public offering price of $10.00 per unit and the application of the net proceeds of this offering, the net tangible book value of TASER as of December 31, 2000 would have been $4,640,145, or $1.85 per share. This represents an immediate increase of $4.20 per share of common stock to existing stockholders and an immediate dilution of $8.15 per share of common stock to the new investors who purchase units in this offering. The following table illustrates this per share dilution:

      If the representative’s over-allotment option is exercised in full, dilution per share to new investors would be $7.76 per share of common stock.

      The following table summarizes as of December 31, 2000 the differences between the existing stockholders and the new investors with respect to the number of shares of common stock purchased, the total consideration paid, and the average price per share paid:

      The above computations assume no exercise of outstanding options or warrants to purchase common stock, the representative’s over-allotment option, the public warrants included in units sold in this offering or the representative’s warrants. To the extent that these options and warrants are exercised, there will be further dilution to new investors.

Overview

      We began operations in Arizona in 1993 for the purpose of developing and manufacturing less-lethal self-defense devices. From inception until the introduction of our first product, the AIR TASER, in 1994, we were in the development stage and focused our efforts on product development, raising capital, hiring key employees and developing marketing materials to promote our product line.

      In 1995 and 1996, we focused our efforts on promoting retail sales and establishing distribution channels for the AIR TASER product line. However, our marketing efforts were limited by a non-compete agreement prohibiting the company from marketing or selling our products to the U.S. law enforcement and military markets. Accordingly, initial sales of the AIR TASER were limited to the consumer market. While early sales in this market were promising, by the end of 1996 we were unable to establish consistent sales channels in the consumer marketplace and sales declined. In late 1996, we relocated our production facilities to Mexico to reduce production costs.

      In 1997, we introduced our second product line, the AUTO TASER. The initial market response to the AUTO TASER suggested the demand for this product would more than compensate for the declining AIR TASER sales. Because of strong pressure from pre-production orders, we accelerated the development of the AUTO TASER. As a result of this acceleration, production costs of the AUTO TASER far exceeded initial projections, and we experienced a substantial amount of AUTO TASER returns due to product defects.

      The non-compete agreement that had precluded sales to the law enforcement and military markets expired in 1998. During this year, we focused our development efforts on the ADVANCED TASER product line, a redesigned and enhanced version of the AIR TASER, targeted primarily to the U.S. law enforcement and corrections market. During 1998, in addition to $66,000 paid to outside research and development consultants, we also incurred substantial internal unallocated expenses associated with the development of the ADVANCED TASER. Further, end-user sales of the AUTO TASER continued to decline, and product returns remained higher than expectations.

      In August 1999, the AUTO TASER product line was discontinued and we closed our production facilities in Mexico. We sold all remaining finished goods associated with the AUTO TASER product line by the end of the first quarter of 2000. We outsourced the production of our remaining finished goods and non-proprietary components to a third-party assembler. We shifted our focus to completion of the ADVANCED TASER development project and introduced the first ADVANCED TASER units for sale to law enforcement customers in December 1999. As a result of these activities and product development expenses, we had accumulated a deficit of $6.3 million by December 31, 1999.

      The first full year of the ADVANCED TASER product line sales was 2000. We spent the year focusing on building the distribution channel for marketing the product line and developing a nationwide training campaign to introduce the product line to law enforcement agencies, primarily in North America.

Results of Operations

      For the years ended December 31, 1999 and 2000, sales by product line were as follows:

      Net sales. Net sales increased $1.1 million, or 48%, from $2.4 million for the year ended December 31, 1999 to $3.5 million for the year ended December 31, 2000. The increase was due almost entirely to the first full year of sales of the ADVANCED TASER, primarily to law enforcement agencies. The increase in sales was partially offset by the decline in AUTO TASER sales due to the discontinuation of this product line and somewhat lower sales of the AIR TASER to consumers.

      Cost of products sold. Cost of products sold decreased from $1.5 million in 1999, or 63% of net sales, to $1.4 million in 2000, or 41% of net sales. The decrease in cost of products sold as a percentage of net sales was due primarily to the lower direct production costs associated with the AIR and ADVANCED TASERs, which averaged 33% of gross sales as compared to 55% of gross sales for the AUTO TASER, and a one-time charge related to the phase out of the AUTO TASER product line of approximately $355,000 in 1999.

      At December 31, 2000, our principal product costs included the following:

	•	Direct materials: Direct materials include raw materials and sub-assemblies sold to our contract manufacturer for insertion into the final production assemblies as well as supplies used in production. Direct materials represent the majority of our cost of products.
	•	Direct labor: Direct labor represents the expenses incurred in our Scottsdale, Arizona facility for the assembly and packaging of sub-assemblies. Once finished, these sub-assemblies are sold to our contract manufacturer for insertion in finished product. Prior to 2000, direct labor included wages paid to employees in our Mexico production facility.
	•	Shipping expense: Shipping expense includes those costs associated with shipping finished products to our customers. This includes freight paid to ship orders, special handling charges and related transaction fees.

      In 2001, we anticipate that direct labor will represent a larger portion of cost of products sold as we move final assembly to our facility in Scottsdale.

      Gross profit. Gross profit increased $1.2 million, or 136%, from $874,000 in 1999 to $2.1 million in 2000. Our gross profit margin was 37% of net sales in 1999 compared to 59% in 2000 due to increased sales of higher margin ADVANCED TASER products and the write offs taken in 1999 as a result of the phase out of the AUTO TASER.

      Operating expenses. Operating expenses decreased $203,000, or 32%, from $634,000 in 1999 to $431,000 in 2000. Operating expenses were 27% of net sales in 1999 compared to 12% of net sales in 2000. This reduction in operating expenses is due largely to the closure of our manufacturing facility in Mexico in August 1999, and the associated reduction in staff when we outsourced production and assembly. Operating expenses are the indirect costs associated with producing our products, such as rent on production facilities, engineering and support salaries and other indirect manufacturing costs. We do not anticipate proportionate increases in operating expenses in the event our revenues increase.

      Sales, general and administrative expenses. Sales, general and administrative expenses increased by $163,000, or 12%, from $1.4 million in 1999 to $1.5 million in 2000. Sales, general and administrative

15

      Interest expense. Interest expense increased by $88,000, or 31%, from $281,000 in 1999 to $369,000 in 2000. The increase reflects the cost of the higher level of related party debt in 2000 over 1999, primarily used to fund working capital. In addition, we issued warrants and options in 2000 valued at $26,000 to certain stockholders for loan guarantees.

      Corporate tax status. Prior to our re-incorporation in Delaware in February 2001, we were an S-corporation, which allowed all the tax attributes to flow through to the stockholders. In February 2001, we changed our tax reporting status to that of a C-corporation. When we changed our reporting status, all accumulated shareholder deficit was converted to additional paid-in capital. As a result there are no net operating loss carry forwards available to us.

      Net loss. The net loss decreased $1.2 million, or 74%, from $1.6 million in 1999 to $416,000 in 2000. Basic and diluted net loss per common share was $0.52 in 1999 compared to $0.17 in 2000. The reduced net loss in 2000 resulted primarily from increased sales volume and increased gross margins attributable to sales of the ADVANCED TASER line.

Liquidity and Capital Resources

      Liquidity. We had a working capital deficiency of $2.4 million at December 31, 1999 and $1.0 million at December 31, 2000. The improvement in working capital from 1999 to 2000 was largely due to the extension of short-term related party debt to long-term debt. In both 1999 and 2000, cash was used primarily to fund operating losses and for investment in property and equipment. We have historically addressed our working capital shortfalls through capital investment and debt financing from related parties.

      In 2000 we generated cash from operations of $66,000, primarily as a result of a significant customer deposit of $440,000 received in December 2000. In 1999, operations consumed $705,000 in cash. Although we anticipate that our cash flow from operations will be at least break-even in 2001, we have not historically generated sufficient cash from operations to fund future growth or to repay our long-term debt that principally comes due July 1, 2002.

      We anticipate that, after the completion of this offering, our cash resources will be adequate to meet our liquidity needs for at least the next 12 months. There can also be no assurances that our working capital objectives will be reached in the near future, if ever. If additional capital is required, it may not be available on favorable terms or at all.

      Capital resources. In the past, we have funded our operating deficits primarily through indebtedness to related parties. Our indebtedness to stockholders and related parties totaled $2.9 million at December 31, 2000. The majority of this indebtedness matures at the earlier of the completion of this offering or July 2002. The indebtedness bears interest ranging from 9% to 27%. A significant portion of this indebtedness will be repaid from the proceeds of this offering, including the representative’s over-allotment option, if exercised.

      Capital commitments. At December 31, 2000, we had no material commitments for capital expenditures. Other commitments include rental payments under operating leases for office space and equipment, and commitments under employment contracts with our chief executive officer, president, and chief financial officer.

BUSINESS

Company overview

      We develop, assemble and market less-lethal, conducted energy weapons primarily for use in the law enforcement and corrections market. Over 350 police departments in the United States have made initial purchases of our products and 15 police departments, including San Diego, Sacramento, and Albuquerque, have purchased our products for every patrol officer. As of February 1, 2001, more than 200 additional police departments were evaluating our newest product, the ADVANCED TASER.

      We sell two principal products. We introduced the AIR TASER in 1994 and targeted it primarily at the consumer market. We designed the AIR TASER to look like a cellular telephone or other consumer electronic item, rather than a weapon. The terms of an agreement we signed with Electronic Medical Laboratories, Inc., doing business as Tasertron and the original licensee of a patent on certain technology used in our weapons, precluded us from selling our products to United States law enforcement, corrections and military agencies until February 1998. After expiration of this agreement, we introduced the ADVANCED TASER, an upgraded and redesigned version of the AIR TASER, to appeal to the law enforcement and corrections market. It uses the same basic operating principle as the AIR TASER but produces four times the AIR TASER’s power output. It is also pistol-shaped to make it easier for police officers to use. The ADVANCED TASER can be sold with an integrated laser sight and a built-in memory option to record the time and date of up to 585 firings. We believe the ADVANCED TASER will also appeal to the security, military and consumer markets, and intend to pursue sales in these markets after further penetrating the law enforcement and corrections market.

Industry background

      The market for less-lethal weapons includes law enforcement agencies, correctional facilities, military agencies, private security guard companies and retail consumers. We believe law enforcement officials are the opinion leaders regarding market acceptance of new security products. In recent years, successful new security products — such as the GLOCK handgun and the Mag-Lite flashlight — were first marketed to and accepted by police departments. We therefore focus on the law enforcement agency segment of the market for less-lethal weapons.

      Generally, each police force has a use-of-force policy that dictates the level of force its officers can use to respond to various situations. A police officer is trained to use only the minimum force necessary to overcome the threat of injury or violence posed by a suspect. For example, under most policies, an officer may not use lethal force unless a subject poses a threat of significant bodily injury or fatality to the officer or other persons.

      In fact, most police officers never deploy lethal force in the course of their careers. While the vast majority of law enforcement officers around the world are armed with firearms, only a small percentage will actually ever use them. Many police officers, however, must use less-lethal force on a regular basis. Less-lethal force can range from a control hold to the use of a baton, chemical spray, or other means to control a subject that is actively resisting the officer.

      Police officers are often injured while trying to subdue a suspect with less-lethal force. Traditional tactics such as using a baton or fist to control a suspect result not only in a significant risk of injury to the suspect, but also a significant risk that the officer will be injured. If an officer can subdue a suspect from a safe distance using effective less-lethal weapons, he greatly reduces the probability that he or the suspect, as well as bystanders, will be injured during a confrontation.

      A variety of new less-lethal weapons have been developed to address the need to temporarily incapacitate an attacker without causing permanent injury or fatality. These weapons vary in approach, but generally include stun guns, batons and clubs, chemical sprays, rubber bullets, pepper balls and other impact munitions. Each weapon has distinct advantages and disadvantages, and law enforcement agencies

17

	•	Effectiveness: temporary incapacitation of aggressive suspects;
	•	Range: variable distance over which the weapon is effective;
	•	Safety: low risk of injury or death;
	•	Ease of use: simple operation, low maintenance and no contamination;
	•	Dependability: reliability in many environments, product durability;
	•	Accountability: tracking to reduce misuse of the weapon; and
	•	Cost: low cost per use and possible reduction of litigation expense.

The ADVANCED TASER solution

      All our products are designed to perform well in terms of the above characteristics. We believe the ADVANCED TASER, however, offers the best combination of these characteristics currently available in a less-lethal weapon. This superior performance could make the ADVANCED TASER the less-lethal weapon of choice in many situations for law enforcement agencies and other security services.

	•	Effectiveness

      Most less-lethal weapons rely upon a pain response for effect. A less-lethal weapon that inflicts only pain may not stop the most dangerous and aggressive suspects. The ADVANCED TASER is designed to cause complete yet temporary physical incapacitation, not just discomfort or distraction. In police testing and field use, the ADVANCED TASER has incapacitated even highly focused individuals who have demonstrated the ability to fight through other less-lethal weapons that rely only on pain.

	•	Range

      Batons and chemical sprays can only be used from close distances, usually less than five feet. Rubber bullets, beanbag rounds, and similar less-lethal impact weapons must be used at distances greater than 30 feet to minimize suspects’ injuries. Therefore, we believe that other less-lethal weapons as a group are generally ineffective between five and thirty feet. The ADVANCED TASER is designed to operate within this range. Since it is equally effective at very close range, we believe the ADVANCED TASER represents a more versatile less-lethal weapon for encounters taking place within 21 feet.

	•	Safety

      In tests involving over 1,000 human volunteers and in hundreds of field applications, the ADVANCED TASER has had no reported long-term, adverse after-effects. In field uses, our technology has been found to have a comparable or lower risk of injury to officers and suspects than other less-lethal technologies. Further, the recovery time from an application of the ADVANCED TASER is generally less than one minute. In contrast, recovery time from the application of chemical sprays can range from ten minutes to one hour. Recovery time from the effect of impact rounds can vary from hours to weeks, depending on bruising and bone breakage.

	•	Ease of Use

      The ADVANCED TASER is shaped and designed to function like a standard handgun. Accordingly, it is easy for law enforcement officers to use during stressful situations, since their firearms training familiarizes them with the muscle movements required for its operation. Further, the weapon requires no maintenance other than a periodic battery check. The ADVANCED TASER also does not leave contaminating residues, unlike chemical sprays that may contaminate buildings, vehicles or other closed facilities or officer uniforms.

18

	•	Dependability

      The ADVANCED TASER operates effectively under a variety of unfavorable conditions, such as wind and rain, that render chemical sprays less effective. The ADVANCED TASER housing is constructed of high tensile-strength polycarbonate to withstand the rigors of typical police use.

	•	Accountability

      The ADVANCED TASER incorporates features designed to reduce inappropriate use. Our cartridges contain numerous confetti-like Anti-Felon Identification tags, or AFIDs, which are scattered when the unit is fired. AFID tags recovered from usage sites can thus help identify the owner of the cartridge used. The ADVANCED TASER we market to law enforcement and corrections agencies also comes with a data port that records the exact time, date and duration of up to 585 firings.

	•	Cost

      The ADVANCED TASER is sold to law enforcement agencies for approximately $400 per unit. The air cartridge ammunition is priced under $18 per shot. These prices are competitive with impact munitions and most other specialized less-lethal weapons, with the exception of the least expensive chemical sprays. However, the indirect costs of decontaminating buildings, vehicles, and uniforms resulting from the use of chemical sprays can place the ADVANCED TASER at an overall cost advantage per use.

      In addition, litigation costs for law enforcement agencies can be significant. Reducing the number of injuries and fatalities caused by law enforcement officers may reduce the number of suits filed against agencies for excessive use of force, wrongful death and injury. Further, reducing officer injuries minimizes medical claims and lost time for work-related injuries.

      As with other less-lethal weapons, these characteristics, particularly safety, may also have the benefit of increasing goodwill between law enforcement agencies and their communities. Community relations considerations can be particularly important at a time when almost any interaction with police can be videotaped and scrutinized by the media and the public.

Our strategy

      Key elements of our strategy for growth include the following:

	•	Fully exploit the expanding law enforcement and corrections market .

      Our goal is to make the ADVANCED TASER the dominant less-lethal weapon for use by law enforcement and corrections agencies. Law enforcement officials are often viewed as experts with regard to weapons and other security products. As a result, we believe that widespread acceptance of the ADVANCED TASER in this market will enhance its credibility and represent a necessary first step toward expanding sales of our products in additional markets.

	•	Expand into private security, military, and consumer markets .

      After increasing our presence in the law enforcement and corrections market, we intend to expand our penetration in the private security, military and consumer self-defense markets. We believe the same performance characteristics that will enable our products to succeed in the law enforcement and corrections market will also appeal to potential customers in these additional markets.

	•	Develop enhanced less-lethal weapon technologies .

      We intend to improve our less-lethal weapons technology to provide further growth and market opportunities. Among other things, we intend to develop multiple shot capability and greater effective range. These innovations may increase our revenues by allowing us to sell upgraded less-lethal weapons and accessories, both to existing and potential new customers.

19

	•	Acquire businesses that enhance our strategic position .

      We may acquire businesses that will complement our growth strategy and enhance our competitive position in our markets. However, we have no current plans for such acquisitions.

Markets

   Law enforcement and corrections

      Federal, state and local law enforcement agencies in the United States currently represent the primary target market for the ADVANCED TASER. According to United States Bureau of Justice statistics, there were nearly 19,000 of these agencies in the United States in 1996 that employed about 740,000 full-time, sworn law enforcement officers. In 1995, industry analysts estimated that the total number of non-administrative correctional officers in the United States was approximately 450,000.

      Acceptance of the ADVANCED TASER by United States police departments has been fairly rapid since its introduction in December 1999. We believe it could prove equally suitable for use in correctional facilities. The ADVANCED TASER is particularly useful in these confined and crowded settings since it provides a means of bringing virtually any individual under control without requiring the use of lethal force. We anticipate that some correctional officers will be armed with ADVANCED TASERs, particularly as its performance attributes become more familiar to the wider law enforcement community.

      In the law enforcement market, over 350 police departments have made initial purchases of the ADVANCED TASER for testing or deployment. In addition, 15 police departments, including San Diego, Sacramento, and Albuquerque, purchased enough of our weapons to issue one to each of their patrol officers.

   Private security firms and guard services

      In 1999, it was estimated that there were over 1.7 million privately employed security guards or personnel in the United States. They represent a broad range of individuals, including bodyguards, commercial and government building security guards, commercial money carrier employees, and many others. We believe that security personnel armed with ADVANCED TASERs could be as effective in many circumstances as those armed with conventional firearms. At the same time, arming guards with ADVANCED TASERs may reduce the potential liability of private security companies and personnel.

      A number of environments can prove problematic for the use of conventional firearms. The use of conventional firearms in airplanes, for example, poses a significant threat to the integrity of the aircraft and the safety of the passengers. Conventional firearms may also be inappropriate in subways, buses, transit systems, banks and casinos. In many of these crowded environments, the contamination associated with the use of chemical sprays could also pose significant problems.

      One large private security force overseas has ordered over 1,000 ADVANCED TASERs for delivery in Spring 2001. We are in the early stage of pursuing additional opportunities for sales of the ADVANCED TASER in private security markets, and have made only limited sales to date.

   Consumer/personal protection

      In the late 1990s, industry sources estimated that 35 million Americans owned handguns. We believe these handgun owners represent one segment of a potentially large consumer market for our products.

      As a result of our shift in focus, the share of our sales made to consumer markets fell sharply from 1999 to 2000. In 1999, sales to consumers represented 88% of total revenues while these sales dropped to only 32% of total sales in 2000. We expect the relative share of sales to consumer markets to remain small in the next few years. Given the size of the potential consumer market, however, we believe consumer sales could contribute a substantial portion of our revenues in the future, particularly if the ADVANCED TASER becomes more established in the law enforcement and corrections market.

20

   Military

      Military police forces may use the ADVANCED TASER for purposes similar to those of civilian police units. Military peace-keeping forces also perform policing functions, and the ADVANCED TASER may prove an effective tool for these operations. The ADVANCED TASER may also be used by armed forces to reduce the possibility of civilian casualties resulting from combat operations on battlefields consisting of both civilians and combatants. We have yet to pursue sales opportunities in the military market.

Products

      Our weapons use compressed nitrogen to shoot two small electrified probes up to a maximum distance of 21 feet. The probes and compressed nitrogen are stored in a replaceable cartridge attached to the base of the weapon. Our proprietary replacement cartridges are sold separately.

      After firing, the probes discharged from our cartridges remain connected to the weapon by high-voltage insulated wires that transmit electrical pulses into the target. These electrical pulses, which we call TASER-Waves or T-Waves, are transmitted through the body’s nerves in a manner similar to the transmission of signals used by the brain to communicate with the body. The T-Waves temporarily overwhelm the normal electrical signals within the body’s nerve fibers, impairing subjects’ ability to control their bodies or perform coordinated actions. T-Waves can penetrate up to two inches of clothing. The initial effect lasts up to five seconds and the charge can be repeated for up to approximately ten minutes by repeatedly firing the weapon.

      Since all our weapons use the same cartridges, we can support multiple platforms and still achieve economies of scale in cartridge production. Our cartridges contain numerous colored, confetti-like tags bearing the cartridge’s serial number. These tags, referred to as Anti-Felon Identification tags, or AFIDs, are scattered when one of our weapons is fired. We require sellers of our products to participate in the AFID program by registering buyers of our cartridges. In many cases, we can use AFIDs to identify the registered owner of cartridges fired.

      We introduced our initial product, the AIR TASER, in 1994. We designed the AIR TASER to look like a cellular telephone rather than a weapon to target the consumer electronics market. Currently, the AIR TASER product line consists of the AIR TASER, a cartridge that shoots two small electrified probes up to 15 feet, an optional laser sight, and a number of holstering accessories. We continue to target the AIR TASER line to the consumer market.

      We developed the ADVANCED TASER product line, launched in December 1999, primarily for the law enforcement and corrections market. The ADVANCED TASER M26 is our primary product in this market and is sold exclusively to law enforcement and corrections agencies. The ADVANCED TASER M26 offers the following improvements over the AIR TASER:

	•	Increased effectiveness:  the ADVANCED TASER has four times the power of the AIR TASER and has proven effective in incapacitating over 99% of volunteers tested.
	•	Better accountability:  the ADVANCED TASER’s memory system records the time, date, and duration of up to 585 firings. By downloading this information periodically, law enforcement and corrections agencies can track every use of the ADVANCED TASER. These agencies can use this data to investigate potential misuse.
	•	Ease of use:  the ADVANCED TASER’s familiar pistol shape and integrated laser sight minimize the training required for law enforcement and corrections officers and make it easier to use.

      Our products are sold primarily through our network of distributors at a wide range of prices. Our most inexpensive consumer product is the entry-level consumer AIR TASER, with a retail price of $99. Our high-end consumer model, the ADVANCED TASER M18L with integrated laser sight, retails for $600. The ADVANCED TASER M26 is currently our best selling item. Distributors sell the M26 to law enforcement and corrections agencies for $400. Retail cartridge prices range from $16 to $30 per unit.

21

      In addition to weapons and cartridges, we sell holsters, attachments, cases and other accessories that complement our core products. Although to date these accessories have generated limited sales, they offer additional revenue opportunities and attractive margins.

      We offer a lifetime warranty on the AIR TASER. Under this warranty, we will replace any AIR TASER that fails to operate properly for a $25 fee. The AIR TASER is designed to disable an attacker for up to 30 seconds, and we encourage users to leave the unit and flee after firing it. As a result, we also provide free replacement units to consumers who follow this suggested procedure. To qualify for the replacement unit, users must file a police report that describes the incident and confirms the use of the AIR TASER.

      We offer a no-questions-asked lifetime replacement policy on the ADVANCED TASER. If the weapon fails to operate properly for any reason, we will replace it for a fee of $25. The fee is intended to help defray the handling and repair costs associated with product returns. This policy is attractive to our law enforcement and corrections agency customers. In particular, it avoids disputes regarding the source or cause of any defect. Warranty costs under both the AIR TASER and the ADVANCED TASER replacement policies have been minimal to date.

Sales and marketing

      Law enforcement and corrections agencies represent our primary target market. In this market, the decision to purchase the ADVANCED TASER is normally made by a group of people including the agency head, his training staff, and weapons experts. The decision sometimes involves political decision-makers such as city council members. The decision-making process can take as little as a few weeks or as long as several years.

      United States distribution. With the exception of several accounts to which we sell directly, the vast majority of our law enforcement agency sales in the United States occur through our network of more than 25 independent regional police equipment distributors. To service these distributors and assist us in expanding sales to new ones, we retain two manufacturer’s representatives that call on potential distributors. We compensate our manufacturer’s representatives solely on a commission basis, calculated as a percentage of the sales they complete. Sales in the consumer market are made through different independent distributors, dealers, and retailers. We provide our distributors with performance-based incentive programs.

      International distribution. As a result of our shift in focus to the United States law enforcement and corrections market, our international sales efforts are currently limited to presentations and training seminars conducted by TASER personnel. We recently began introducing the ADVANCED TASER in Europe and parts of the Middle East, South America and Asia, but have yet to devote significant resources to these markets. Sales outside the United States and Canada accounted for 48% and 18% of total revenues in 1999 and 2000, respectively. In 2001, we expect international sales to account for approximately 10% of our total sales.

      We have worked in the past with more than 20 foreign distributors. These foreign distributors purchase products from us and resell them to sub-distributors, retail dealers or end users. We continue to provide most foreign distributors with short-term exclusive contracts to sell our products in a designated region. Although many of these relationships are inactive, we continue to ship products as ordered.

      Training Programs. Most law enforcement and corrections agencies will not purchase new weapons until a training program is in place to certify all officers in their proper use. We offer an eight-hour class that certifies law enforcement and corrections agency trainers as instructors in the use of the ADVANCED TASER. We have certified over 2,500 law enforcement training officers as ADVANCED TASER instructors. Our certification program is designed to make it easier for departments to comply with these training requirements.

      Fifty of our certified instructors have undergone further training and become certified as master instructors. We authorize these individuals to train other law enforcement and corrections agency trainers,

22

      Communications. In addition to our training programs, we regularly participate in a variety of trade shows and conferences. Our marketing efforts also benefit from significant free news coverage. Other marketing communications include video e-mails, press releases, and conventional print advertising in law enforcement trade publications. Our website also contains similar marketing information.

Manufacturing

      After a review of our operating costs and changes in regulations pertaining to the export of the technology used to produce our weapons, we elected to move our final assembly operations from our subcontractor in Guaymas, Mexico to our new facility in Scottsdale, Arizona. We own all of the production equipment used for the final assembly of our products in the Guaymas facility, and expect to reinstall it in Scottsdale no later than April 2001. We currently assemble the compressed nitrogen containers used inside our air cartridges in our Scottsdale facility.

      Our Scottsdale facility has approximately 6,000 square feet of assembly and warehouse space. We plan to employ between 15 and 25 assembly personnel by the end of 2001. After the move, our production capabilities will support the assembly of 2,000 ADVANCED TASERs, 1,000 AIR TASERs, and 24,000 cartridges per month on a single shift. We can expand our production capabilities by adding additional personnel and a second shift with negligible new investment in tooling and equipment. We expect our Scottsdale facility and tooling to be sufficient to support our current growth projections at least through 2003.

      We currently purchase finished circuit boards and injection-molded plastic components from third-party suppliers in Phoenix. Although we currently obtain these components from single source suppliers, we own the injection-molded component tooling used in their production. As a result, we believe we could obtain alternative suppliers without incurring significant production delays. We acquire most of our components on a purchase order basis and do not have long-term contracts with suppliers.

Competition

      In the law enforcement and corrections market, the ADVANCED TASER competes directly with the conducted energy weapon sold by Electronic Medical Research Laboratories, Inc., doing business as Tasertron. Tasertron is the sole remaining manufacturer of the original TASER weapon introduced in the 1970s. The ADVANCED TASER also competes indirectly with a variety of other less lethal alternatives. In the consumer market, the AIR TASER competes directly with a conducted energy weapon introduced by Bestex, Inc. in 1996, called the Dual-Defense, and indirectly with other less-lethal alternatives.

      Law enforcement and corrections market. Tasertron had an exclusive license to sell TASER products in the North American law enforcement and corrections market until February 1998. Compared to the Tasertron unit, our ADVANCED TASER offers reduced size, additional power, and a more convenient pistol-shaped design. We believe agencies choosing to employ a conducted energy weapon will prefer to adopt a single weapon system. Since its introduction, the ADVANCED TASER has competed successfully against the Tasertron unit, even in agencies that had previously purchased Tasertron units.

      Other less-lethal weapons, sold by companies such as Armor Holdings, Inc. and Jaycor, Inc., compete with our ADVANCED TASER indirectly. Many law enforcement and corrections personnel consider less-

23

      Consumer market. Conducted energy weapons have gained limited acceptance in the consumer market for less-lethal weapons. These weapons compete with other less-lethal weapons such as stun guns, batons and clubs, and chemical sprays. The primary competitive factors in the consumer market include a weapon’s cost, its effectiveness, and its ease of use. The widespread adoption of the ADVANCED TASER by law enforcement agencies may help us overcome a perceived historic lack of consumer confidence in conducted energy weapons.

Regulation

      United States regulation. The AIR TASER and ADVANCED TASER are subject to the same regulations. Neither weapon is considered a “firearm” by the Bureau of Alcohol, Tobacco, and Firearms. There are, therefore, no firearms-related regulations regarding the sale and distribution of our weapons within the United States. In the 1980s, however, many states introduced regulations restricting the sale and use of stun guns, inexpensive hand-held shock devices. We believe existing stun gun regulations also apply to our weapon systems.

      In many cases, the law enforcement and corrections market is subject to different regulations than the consumer market. Where different regulations exist, we assume the regulations affecting the consumer market also apply to the private security market. Based on a review of current regulations, we have determined the following states regulate the sale and use of our weapon systems:

24

      The following cities and counties also regulate our weapon systems:

      United States export regulation. Our weapon systems are considered a crime control product by the United States Department of Commerce. Accordingly, the export of our weapon systems is regulated under the export administration regulations. As a result, we must obtain export licenses from the Department of Commerce for all shipments to foreign countries other than Canada. Most of our requests for export licenses have been granted, and the need to obtain these licenses has not caused a material delay in our shipments. The need to obtain licenses, however, has limited or impeded our ability to ship to certain foreign markets. In addition, export regulations prohibit the further shipment of our products from foreign markets in which we hold an export license for the products to foreign markets in which we do not hold an export license for the products.

      In addition, in the fall of 2000, the Department of Commerce introduced new regulations restricting the export of the technology used in our weapon systems. These regulations apply to both the technology incorporated in our weapon systems and in the processes used to produce them. The technology export regulations do not apply to production that takes place within the United States. After moving our final assembly to our Scottsdale facility, these technology export regulations will no longer apply to us but will still apply to certain of our suppliers located outside of the United States.

      Foreign regulation. Foreign regulations are numerous and often unclear. We prefer to work with an exclusive distributor who is familiar with applicable regulations in each of our foreign markets. Experience with foreign distributors in the past indicates that restrictions may prohibit certain sales of our products in a number of countries. The countries in which we are aware of restrictions include Belgium, Denmark, Hong Kong, Italy, Japan, New Zealand, Norway, Sweden, Switzerland, and the United Kingdom. In Australia, Canada, and India we are also aware that sales of our products are permitted to law enforcement and corrections agencies but prohibited to consumers.

Intellectual property

      We protect our intellectual property with a variety of patents and trademarks. In addition, we use confidentiality agreements with employees and some suppliers to ensure the safety of our trade secrets. We hold a United States patent on the construction of the gas cylinder used to store the compressed nitrogen in our cartridges. This patent expires in 2015. We are the licensee of a United States patent on the process by which compressed gases launch the probes in our cartridges. This patent expires in 2009. Using this compressed gas technology instead of gunpowder prevents our products from being classified as firearms by the Bureau of Alcohol, Tobacco and Firearms. We also have a broad-based patent application pending covering the wave form of the energy we developed for the ADVANCED TASER.

      We have several unregistered and federally registered trademarks. We own the AIR TASER and TASER registered trademarks.

Research and development

      Our research and development initiatives are led by our internal personnel and make use of specialized consultants when necessary. These initiatives include bio-medical research as well as electrical

Fiscal year end option values

      The following table sets forth information regarding the number and value of unexercised options held by our chief executive officer on December 31, 2000. He did not exercise options to purchase common stock during 2000.

Stock option plans

      We have two stock option plans: the 1999 stock option plan and the 2001 stock option plan.

      The 1999 stock option plan is an incentive and stock option plan which authorizes us to issue options to purchase up to 833,333 shares of our common stock. Under this plan, we have issued options to purchase 143,322 shares at $0.24 to $7.20 per share, including 10,000 options to Patrick W. Smith. We will issue no further options under the plan. The plan is administered by our board of directors. Subject to the provisions of this plan, the board determines who will receive options, the number of options granted, the manner of exercise and the exercise price of the options. The term of incentive stock options granted under the plan may not exceed ten years, or five years for options granted to an optionee owning more than 10% of our voting stock. The exercise price of an incentive stock option granted under this plan must be equal to or greater than the fair market value of the shares of our common stock on the date the option is granted. The exercise price of a non-qualified option granted under this plan must be equal to or greater than 85% of the fair market value of the shares of our common stock on the date the option is granted. An incentive stock option granted to an optionee owning more than 10% of our voting stock must have an exercise price equal to or greater than 110% of the fair market value of our common stock on the date the option is granted.

      The 2001 stock option plan is an incentive and stock option plan which authorizes us to issue options to purchase up to 550,000 shares of our common stock. Under this plan, we have issued options to purchase 291,000 shares at an average price of $8.33 per share, including 60,000 options to Patrick W. Smith. The plan is administered by our board of directors. Subject to the provisions of this plan, the board determines who will receive options, the number of options granted, the manner of exercise and the exercise price of the options. The term of incentive stock options granted under the plan may not exceed ten years, or five years for incentive stock options granted to an optionee owning more than 10% of our voting stock. The exercise price of an incentive stock option granted under this plan must be equal to or greater than the fair market value of the shares of our common stock on the date the option is granted. The exercise price of a non-qualified option granted under this plan must be equal to or greater than 85% of the fair market value of the shares of our common stock on the date the option is granted. An incentive stock option granted to an optionee owning more than 10% of our voting stock must have an exercise price equal to or greater than 110% of the fair market value of our common stock on the date the option is granted.

Employment agreements

      In July 1998, we entered into an employment agreement with Patrick W. Smith pursuant to which he agreed to serve as our chief executive officer. The agreement is for an initial three-year term ending June 30, 2001, and is automatically renewed for a two-year term on such date and every two years thereafter unless we give Mr. Smith one-year prior notice of termination, if the termination is without cause. The agreement provides for annual base compensation in the amount of $65,000, which amount may be increased based on performance. In 2000, Mr. Smith’s salary was increased to $90,000. We may terminate this agreement with or without cause. Should we terminate the agreement without cause, upon a change of control or upon his death or disability, our chief executive officer is entitled to compensation equal to 12, 24 or 18 months of salary, respectively.

CERTAIN TRANSACTIONS

      In 1998, Mr. Bruce R. Culver, a director of TASER, loaned us $622,525. In March 1998, $150,000 of such amount was converted into 20,833 shares of our common stock at an estimated value of $7.20 per share. In December 1998, we issued Mr. Culver a promissory note for $472,525, the remaining amount due. The note bears interest at a rate of 10% per year and matures July 1, 2002. In 1999, Mr. Culver loaned an additional $150,000 to us at an interest rate of 10%, due July 1, 2002. In 2000, Mr. Culver loaned an additional $200,000 to us at an interest rate of 10%, due July 1, 2002. As of December 31, 2000, the aggregate amount due to Mr. Culver under these notes was $822,525 in principal plus accrued interest of $140,794.

      In January 1999, Mr. Culver loaned us $1,500,000. In return, we issued him a promissory note for $500,000 at an effective interest rate of 27.1% per year, and 1,666,667 shares of our common stock at a price of $0.60 per share. These shares were subject to a repurchase agreement between Mr. Culver and us that allowed us to repurchase the shares if we met certain operating performance criteria. We met the criteria and repurchased the shares from Mr. Culver in July 2000 in exchange for a promissory note in the amount of $1,000,000. We consolidated this note and the January 1999 note for $500,000 into a new note for $1,500,000 which carries interest at bank prime, which was 9.5% at December 31, 2000, plus 1% and matures July 1, 2002.

      In 1998, Mr. Phillips W. Smith, our chairman, loaned us $455,691 in the form of a stockholder note at an interest rate of 9%. This note is currently outstanding, and the maturity has been extended to July 1, 2002 at an interest rate of 10%. Further, Mr. Smith has deferred expenses in the amount of $99,794, which has been formalized in a note bearing 10% interest, which matures July 1, 2002. As of December 31, 2000, the aggregate amount due to Mr. Smith under these notes was $555,485 in principal plus accrued interest of $119,045.

      In 1999, Mr. Smith worked as a full time advisor to us and was compensated solely by an option on 16,667 shares of our common stock at a price of $0.66 per share.

DESCRIPTION OF SECURITIES

      Upon completion of the offering, our authorized capital stock will consist of (1) 50,000,000 shares of common stock, $0.00001 par value, and (2) 25,000,000 shares of preferred stock, $0.00001 par value, of which there will be 2,510,754 shares of common stock and no shares of preferred stock outstanding. The following description of our capital stock is a summary and is qualified in its entirety by the provisions of our certificate of incorporation and our bylaws, copies of which have been filed as exhibits to the registration statement of which this prospectus is a part.

Units

      Each unit consists of one share of common stock and one public warrant to purchase an additional share of common stock. The common stock and warrants will trade only as a unit for at least 30 days following this offering. The representative of the underwriters will then determine when the units separate, after which the common stock and the public warrants will trade separately.

Common stock

      Holders of our common stock are entitled to one vote for each share on all matters submitted to a stockholder vote and may not cumulate their votes. Holders of common stock are entitled to share in all dividends that the board of directors, in its discretion, declares from legally available funds. In the event of our liquidation, dissolution or winding up, each outstanding share entitles its holder to participate pro rata in all assets that remain after payment of liabilities and after providing for each class of stock, if any, having preference over the common stock.

      Holders of our common stock have no conversion, preemptive or other subscription rights, and there are no redemption provisions applicable to our common stock. The rights of the holders of common stock are subject to any rights that may be fixed for holders of preferred stock. All outstanding shares of common stock are, and the shares underlying all options and public warrants will be, duly authorized, validly issued, fully paid and non-assessable upon our issuance of these shares.

Preferred stock

      Our certificate of incorporation provides for the issuance of up to 25,000,000 shares of preferred stock. As of the date of this prospectus, there are no outstanding shares of preferred stock. Subject to certain limitations prescribed by law and the rights and preferences of the preferred stock, our board of directors is authorized, without further stockholder approval, from time to time to issue up to an aggregate of 25,000,000 shares of our preferred stock, in one or more additional series. Each new series of preferred stock may have different rights and preferences that may be established by our board of directors.

      The rights and preferences of future series of preferred stock may include:

	•	number of shares to be issued;
	•	dividend rights and dividend rates;
	•	right to convert the preferred stock into a different type of security;
	•	voting rights attributable to the preferred stock;
	•	right to receive preferential payments upon a liquidation of the company;
	•	right to set aside a certain amount of assets for payments relating to the preferred stock; and
	•	prices to be paid upon redemption of the preferred stock.

Public warrants

   General

      Each public warrant entitles the holder to purchase one share of our common stock at an exercise price per share of 150% of the initial public offering price of the units. The exercise price is subject to adjustment upon the occurrence of certain events as provided in the public warrant certificate and

32

   Separate transferability

      Our public warrants will trade only as a unit for a period of at least 30 days following this offering. The representative of the underwriters will then determine when the units separate, after which the common stock and the public warrants will trade separately.

   Redemption

      We have the right, commencing three months after the closing of this offering, to redeem the public warrants issued in this offering at a redemption price of $0.25 per public warrant after providing 30 days prior written notice to the public warrant holders, if the average closing bid price of the common stock equals or exceeds 200% of the initial public offering price of the units for ten consecutive trading days ending prior to the date of the notice of redemption. We will send the written notice of redemption by first class mail to public warrant holders at their last known addresses appearing on the registration records maintained by the transfer agent for our public warrants. No other form of notice or publication or otherwise will be required. If we call the public warrants for redemption, they will be exercisable until the close of business on the business day next preceding the specified redemption date.

   Exercise

      A public warrant holder may exercise our public warrants only if an appropriate registration statement is then in effect with the Securities and Exchange Commission and if the shares of common stock underlying our public warrants are qualified for sale under the securities laws of the state in which the holder resides.

      Our public warrants may be exercised by delivering to our transfer agent the applicable public warrant certificate on or prior to the expiration date or the redemption date, as applicable, with the form on the reverse side of the certificate executed as indicated, accompanied by payment of the full exercise price for the number of public warrants being exercised. Fractional shares will not be issued upon exercise of our public warrants.

   Adjustments of exercise price

      The exercise price is subject to adjustment if we declare any stock dividend to stockholders or effect any split or share combination with respect to our common stock. Therefore, if we effect any stock split or stock combination with respect to our common stock, the exercise price in effect immediately prior to such stock split or combination will be proportionately reduced or increased, as the case may be. Any adjustment of the exercise price will also result in an adjustment of the number of shares purchasable upon exercise of a public warrant or, if we elect, an adjustment of the number of public warrants outstanding.

Prior warrants

      As of the date of this prospectus, we had issued and outstanding warrants to purchase 52,727 shares of our common stock at a weighted average exercise price of $4.71, the forms of which have been filed as exhibits to the registration statement of which this prospectus is a part.

33

Registration rights

      All holders of registration rights contained in agreements with us have waived such rights in connection with this offering. In connection with this offering, we have granted Paulson Investment Company, Inc., representative of the underwriters of this offering, warrants to purchase shares of our common stock. These representative’s warrants, as well as the shares of common stock and warrants included in the units issuable upon exercise of the representative’s warrants, are being registered on the registration statement of which this prospectus is a part. We will cause the registration statement to remain effective until the earlier of the time that all of the representative’s warrants have been exercised and the date which is five years after the effective date of this offering. The common stock and warrants issued to the representative upon exercise of these warrants will be freely tradeable. We will bear all expenses incurred in connection with the registration of the shares of common stock and warrants included in the units issuable upon the exercise of the representative’s warrants.

Anti-takeover provisions of our charter documents

      Our certificate of incorporation and bylaws include a number of provisions that may have the effect of delaying or preventing a change of control of TASER:

	•	Our board is divided into three classes, with each class serving a three-year staggered term, so that one-third of the board is elected each year;
	•	The authorized number of our directors can be changed only by resolution of the board of directors;
	•	We can issue preferred stock without any vote or further action by stockholders;
	•	Any action required or permitted to be taken by our stockholders at an annual or a special meeting is valid only if it is properly brought before the meeting, and written stockholder action is valid only if unanimous; and
	•	Our bylaws limit persons who may call a special meeting of our stockholders.

These provisions may deter hostile takeovers or delay changes in control of our management, which could depress the market price of our securities.

Of these shares, the 1,000,000 shares of common stock issued as part of the units sold in this offering will be freely tradeable without restrictions or further registration under the Securities Act of 1933, except that any shares purchased by our “affiliates,” as that term is defined under the Securities Act, may generally only be sold in compliance with the limitations of Rule 144 under the Securities Act. The 1,000,000 shares of common stock underlying the public warrants issued as part of the units sold in this offering will also be freely tradeable after exercise of the warrants, except for shares held by our affiliates.

UNDERWRITING

      Paulson Investment Company, Inc. is acting as the representative of the underwriters. We and the underwriters named below have entered into an underwriting agreement with respect to the units being offered. In connection with this offering and subject to certain conditions, each of the underwriters named below has severally agreed to purchase, and we have agreed to sell, the number of units set forth opposite the name of each underwriter.

      The underwriting agreement provides that the underwriters are obligated to purchase all of the units offered by this prospectus, other than those covered by the over-allotment option, if any units are purchased. The underwriting agreement also provides that the obligations of the several underwriters to pay for and accept delivery of the units are subject to the approval of certain legal matters by counsel and certain other conditions. These conditions include the requirements that no stop order suspending the effectiveness of the registration statement be in effect and that no proceedings for such purpose have been instituted or threatened by the Securities and Exchange Commission.

      The representative has advised us that the underwriters propose to offer our units to the public initially at the offering price set forth on the cover page of this prospectus and to selected dealers at such price less a concession of not more than $     per unit. The underwriters and selected dealers may reallow a concession to other dealers, including the underwriters, of not more than $     per unit. After completion of the initial public offering of the units, the offering price, the concessions to selected dealers and the reallowance to their dealers may be changed by the underwriters.

      The underwriters have informed us that they do not expect to confirm sales of our units offered by this prospectus to any accounts over which they exercise discretionary authority.

Over-allotment option

      Pursuant to the underwriting agreement, we have granted Paulson Investment Company, Inc. an option, exercisable for 45 days from the date of this prospectus, to purchase up to an additional                units on the same terms as the units being purchased by the underwriters from us. Paulson Investment Company, Inc. may exercise the option solely to cover over-allotments, if any, in the sale of the units that the underwriters have agreed to purchase. If the over-allotment option is exercised in full, the total public offering price, underwriting discounts and commissions, and proceeds to us before offering expenses will be $          , $          and $          , respectively.

Stabilization

      Until the distribution of the units offered by this prospectus is completed, rules of the Securities and Exchange Commission may limit the ability of the underwriters to bid for and to purchase units. As an exception to these rules, the underwriters may engage in transactions that stabilize the price of the units. Paulson Investment Company, Inc., on behalf of the underwriters, may engage in over-allotment sales, stabilizing transactions, syndicate covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934.

	•	Over-allotment involves syndicate sales in excess of the offering size, which creates a syndicate short position.
	•	Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.

37

	•	Syndicate covering transactions involve purchases of the common stock and public warrants in the open market after the distribution has been completed in order to cover syndicate short positions. The underwriters may also elect to reduce any short position by exercising all or part of the over-allotment option to purchase additional units as described above.
	•	Penalty bids permit the representative to reclaim a selling concession from a syndicate member when the units originally sold by the syndicate member are purchased in a syndicate covering transaction to cover syndicate short positions.

      In general, the purchase of a security to stabilize or to reduce a short position could cause the price of the security to be higher than it might be otherwise. These transactions may be effected on The Nasdaq SmallCap Market or otherwise. Neither we nor the underwriters can predict the direction or magnitude of any effect that the transactions described above may have on the price of the units. In addition, neither we nor the underwriters can represent that the underwriters will engage in these types of transactions or that these types of transactions, once commenced, will not be discontinued without notice.
