                                   THE COMPANY

     We design, manufacture and sell highly selective and sensitive filter
systems for the wireless telecommunications industry. We generate commercial
revenues primarily from sales of our SuperFilter product line which combines
specialized, high-temperature superconducting filters with a proprietary
cryogenic cooler (and, in many cases, a low noise amplifier) in a highly compact
system. Our filter systems enable wireless telecommunication service providers
to improve the quality of voice and data transmissions over their networks.

     High-temperature superconductors are materials that have the ability to
conduct electrical energy with little or no resistance when cooled below
"critical" temperatures. We capitalized on the unique properties of
high-temperature superconductors to develop our SuperFilter product line. When
incorporated into wireless base stations, the SuperFilter products enhance call
quality through improved receiver sensitivity and reduced interference.

     We began a transition from research and development to commercial
production and successfully delivered our first SuperFilter TWO-Pak products in
late 1997. We introduced the TWO-Pak SuperFilter for application in the AMPS/B
segment of the cellular market and later introduced the TWO-Pak SuperFilter for
the AMPS/A segment of the cellular market. We have since added the SIX-Pak
SuperFilter for both A Band and B Band in order to enhance network performance
in urban areas. We continue to add new products to our SuperFilter line and
announced a new family of PCS products for the U.S. market in September of 2000
with field trials scheduled for late 2000 or early 2001.

     A critical component of all superconducting applications is the cryogenic
cooling system. We developed a proprietary cryogenic cooler, which, in addition
to being integrated into our SuperFilter systems, has other potential
applications. These other applications include medical products, cold computing
to increase the processing speed of computers and components of various kinds of
instrumentation.

     We also built our own direct sales and marketing teams. Our initial sales
and marketing efforts were directed primarily at rural and suburban cellular
providers because we believed they were likely to be early adopters of our
product. Our products address the critical needs of these service providers:
coverage and call quality. We now market our SuperFilter products to the urban
market and have begun marketing internationally.

     The augmented SuperFilter product line and increased sales activities
resulted in multiple product orders in 1998, 1999 and 2000. We conducted field
trials of our products with more than 40 cellular service providers, including
nine of the top ten carriers in the country. As a result, we shipped 83
SuperFilter systems in 1998, 123 SuperFilter systems in 1999 and 127 SuperFilter
systems during the six months ended July 1, 2000. In order to prove the economic
benefits of the product, we continue to actively conduct numerous demonstrations
and field trials in the United States and in Latin America.

     We built a new 18,000 square foot state of the art manufacturing facility
in Santa Barbara in 1998. Currently, this facility, along with the manufacturing
equipment and tooling procured, has the capacity to produce up to five
SuperFilter products a day. Operating units within this facility are capable of
producing all the critical components of our products including superconducting
filters, cryogenic coolers, cryogenic packaging and final enclosures, as well as
system assembly and test, quality and material control functions.

     Since our formation in 1987, we have received approximately $58.5 million
in revenue from government research and development contracts through July 1,
2000. These research and development projects generated much of the technology
used in our commercial products. We continue to secure government contracts,
primarily to fund further research and development efforts, and to address
potential wireless product opportunities in the government sector.

     Our principal executive offices are located at 460 Ward Drive, Santa
Barbara, California 93111-2310, and our telephone number is (805) 683-7646.

                                  RISK FACTORS

     You should carefully consider the risks described below, together with all
of the other information included in this prospectus, before making an
investment decision. The risks described below are not the only ones that may
impact us. Additional risks and uncertainties not presently known to us or that
we currently deem immaterial may also have an adverse impact on us. Among other
things, this prospectus contains forward-looking statements that are based on
certain assumptions about the future. We believe that our assumptions are
reasonable. Nonetheless, it is likely that at least some of these assumptions
will not come true. Accordingly, our actual results will probably differ from
the outcomes contained in any forward-looking statements. These differences
could be material.

RISKS RELATING TO OUR COMMERCIAL PRODUCTS BUSINESS

WE HAVE A HISTORY OF LOSSES AND MAY NEVER BECOME PROFITABLE OR GENERATE ENOUGH
CASH FROM OPERATIONS TO SUPPORT OUR BUSINESS PLAN.

     We have experienced significant net losses and negative cash flows from
operations in each our last five fiscal years. We had an accumulated deficit of
$47.1 million as of December 31, 1999 and $54.9 million as of July 1, 2000. We
expect to continue to incur significant net losses for at least the next year
and must significantly increase our revenues to achieve and maintain
profitability. If we fail to increase revenues from sales of our SuperFilter
products, we will continue to experience losses indefinitely.

OUR FUTURE SUCCESS DEPENDS ON OUR ABILITY TO TRANSITION OUR BUSINESS TO FOCUS
PRIMARILY ON COMMERCIAL MARKETS.

     We have derived substantially all of our historical revenues from research
and development contracts with the United States Department of Defense and other
U.S. government agencies. We believe that any future growth we may experience
will depend on our ability to further our transition to developing, marketing
and manufacturing products for the commercial marketplace. Because there are
substantial differences between the requirements for a government contracting
business and a technology product business, we face a number of challenges
arising from our transition. We cannot assure you that we will be successful in
this effort. In particular, we must implement an effective sales and marketing
strategy and volume manufacturing capability, neither of which was required to
support our research and development services business. If we are unable to
effectively transition our business to commercial markets, or if we experience
delays or increased costs resulting from our efforts in this area, our business
will be harmed.

WE HAVE LIMITED EXPERIENCE EVALUATING COMMERCIAL MARKETS FOR WIRELESS NETWORK
INFRASTRUCTURE PRODUCTS, WHICH MAKES IT DIFFICULT TO DETERMINE OUR CURRENT AND
FUTURE BUSINESS PROSPECTS.

     As a result of our recent entry into the commercial wireless market, we
have limited insight into trends that may emerge and affect our business. Our
future operating results will depend upon the increased availability and
acceptance of wireless communications services. We cannot assure you that the
volume and variety of wireless services or the markets for or acceptance of such
services will grow, or that such growth will create a demand for our products.
If the wireless communications market fails to grow, or grows more slowly than
we anticipate, then the market for wireless network infrastructure products such
as ours may not grow in accordance with our expectations, which will harm our
business. Additionally, the market for wireless network infrastructure products
is rapidly evolving. We face many of the same challenges encountered by
early-stage businesses in new and rapidly evolving markets. These factors may
lead us to make errors in predicting and reacting to relevant business trends,
which could harm our business.

OUR SUCCESS DEPENDS ON OUR ABILITY TO DEVELOP NEW PRODUCTS AND PRODUCT
ENHANCEMENTS IN A TIMELY AND COST-EFFECTIVE MANNER.

     We expect that the wireless network infrastructure market will continue to
be characterized by rapid technological change. Our success depends on our
ability to develop and introduce new products and product enhancements that
respond to technological changes and evolving industry standards on a timely and
cost-effective basis. We have in the past experienced, and may in the future
experience, delays in developing our products. We



                                       2
<PAGE>   6



cannot assure you that we will be able to develop new products or product
enhancements in a timely or cost-effective manner, or at all. Any failure to
develop new products or product enhancements will significantly harm our
business.

     Our success in developing new products and product enhancements will depend
on a variety of factors, some of which are beyond our control. These factors
include:

     o    the timely and efficient completion of system design;
     o    the timely and efficient implementation of assembly, calibration and
          test processes; and
     o    the availability of limited source components.

OUR FUTURE GROWTH DEPENDS ON THE COMMERCIAL SUCCESS OF OUR SUPERFILTER PRODUCTS,
AND IF THESE PRODUCTS DO NOT ACHIEVE MARKET ACCEPTANCE, OUR BUSINESS WILL BE
HARMED.

     Our future success depends upon the degree to which our SuperFilter
products are accepted by wireless network operators. We believe that
substantially all of our revenue growth for the foreseeable future will be
derived from sales of our SuperFilter systems. We introduced our first
commercial product, the SuperFilter system, in September 1997, and we have only
limited experience in marketing and manufacturing these products. We have
devoted a significant portion of our resources to the development and perfection
of our 2.5G and 3G wireless products. If our current and future products fail to
meet the needs of our target customers, or of they do not compare favorably in
price and performance to alternative solutions offered by our competitors, our
revenues will not grow. The failure of our products to satisfy our customers'
requirements could delay or prevent the adoption of our products. We cannot
predict with any degree of assurance whether our current or future products will
achieve broad market acceptance, and, if our target customers fail to widely
adopt, purchase and successfully deploy our products, our business will be
harmed.

A NUMBER OF FACTORS MAY CAUSE OUR FINANCIAL RESULTS TO FLUCTUATE AND CAUSE OUR
STOCK PRICE TO DECLINE.

     We expect that our financial results will fluctuate significantly in the
future as a result of our commercial products business. We base our operating
expenses on anticipated commercial product revenue trends, and, therefore, a
significant portion of our expenses are fixed in the short term in anticipation
of these revenue trends. As a result, any delay in generating or recognizing
commercial product revenues could cause our operating results to fall below the
expectations of securities analysts and investors, which would likely cause our
share price to decline. Factors that may cause our stock price to fluctuate
include:

     o    our gain or loss of significant customers;
     o    our ability to increase sales to existing customers;
     o    delays in customer orders;
     o    our ability to reduce manufacturing costs;
     o    our ability to manufacture at acceptable quality levels;
     o    our ability to introduce new filter products or enhancements to our
          existing SuperFilter products;
     o    commercial market acceptance of new products introduced by us or our
          competitors;
     o    our introduction and enhancement of competitive or substitute products
          by our competitors; and
     o    limitations in our existing and future manufacturing capacity.

WE DEPEND ON A LIMITED NUMBER OF WIRELESS NETWORK OPERATORS FOR SUBSTANTIALLY
ALL OF OUR COMMERCIAL REVENUES, AND THE LOSS OF A CUSTOMER OR A DELAY IN AN
ORDER COULD HARM OUR BUSINESS.

     Seven customers have accounted for substantially all of our commercial
sales to date. Our two largest customers accounted for 71% of our gross
commercial product revenues in the year ended December 31, 1999. Our three
largest customers accounted for 80% of our gross commercial product revenues for
the six months ended July 1, 2000. We expect that we will continue to derive a
substantial portion of our commercial net revenues from a relatively small
number of customers in future years. As a result, the loss of, or reduced orders
from any of our customers could harm our financial results and cause our stock
price to decline.



                                       3
<PAGE>   7




THE WIRELESS COMMUNICATION INDUSTRY IS HIGHLY CONCENTRATED, WHICH LIMITS THE
NUMBER OF OUR POTENTIAL CUSTOMERS.

     The wireless communication industry is highly concentrated in nature and
may become more concentrated due to anticipated industry consolidation. As a
result, we believe that the number of potential customers for our products will
be limited. For example, the U.S. wireless operations of three of our
customers--AirTouch, Bell Atlantic and GTE-- were consolidated earlier this year
into one entity called Verizon. More recently, SBC Communications and BellSouth
combined to form Cingular. If the wireless communication industry does not adopt
our products and we fail to capture a significant percentage of the commercial
wireless market customers, our business will be harmed.

THE SALES AND IMPLEMENTATION CYCLES FOR OUR PRODUCTS ARE LONG, AND WE MAY INCUR
SUBSTANTIAL, NON-RECOVERABLE EXPENSES OR DEVOTE SIGNIFICANT RESOURCES TO SALES
THAT MAY NOT OCCUR WHEN ANTICIPATED, OR AT ALL.

     A customer's decision to purchase our products involves a significant
commitment of its resources and a lengthy evaluation and product qualification
process. After a customer decides to purchase our products, the timing of their
deployment and implementation depends on a variety of factors specific to each
customer. Further, prospective customers may delay purchasing our products in
order to evaluate new technologies and develop and implement new wireless
systems. Throughout the sales cycle, we spend considerable resources educating
and providing information to prospective customers regarding the use and
benefits of our products. Our sales cycle for new customers is lengthy,
typically from 6 to 18 months. Because of our limited experience in the
commercial products marketplace, we cannot predict these sales and
implementation cycles.

     Furthermore, because the purchasing process of many wireless network
operators is decentralized, substantial efforts are required to sell our
products throughout our customers' organizations. Entering into a corporate-wide
purchase agreement with a wireless network operator, therefore, does not mean
that we will make sales to the wireless network operator's various divisions.
This may delay widespread deployment of our products and harm our business.

ANY DELAY IN SHIPMENTS TO CUSTOMERS COULD ADVERSELY AFFECT OUR OPERATING
RESULTS.

     Our customers are typically large organizations that make equipment
purchases on their own schedules. We have no influence on their internal
budgetary decisions. Any delay in product shipment could cause revenues and
operating results in a particular period to fall below our expectations as well
as below the expectations of public market analysts or investors. If this
occurs, the trading price of our common stock will likely decline.

     Delays in shipment of our SuperFilter products can happen for a variety of
reasons, including:

     o    unanticipated shipment rescheduling;
     o    cancellation or deferral by a customer;
     o    competitive or economic factors;
     o    lack of qualified manufacturing personnel;
     o    unexpected manufacturing or other difficulties; or
     o    unavailability or delays in deliveries of materials, components,
          subassemblies or services by suppliers.

WE DEPEND ON THE CAPITAL SPENDING PATTERNS OF WIRELESS NETWORK OPERATORS, AND IF
CAPITAL SPENDING IS DECREASED OR DELAYED, OUR BUSINESS WILL BE HARMED.

     Because we rely on wireless network operators to purchase our products, any
substantial decrease or delay in capital spending patterns in the wireless
communication industry will harm our business. The demand for our products
depends to a significant degree upon the magnitude and timing of capital
spending by these operators for constructing, rebuilding or upgrading their
systems. The capital spending patterns of wireless network operators depend on a
variety of factors, including access to financing, the status of federal, local
and foreign government regulation and deregulation, changing standards for
wireless technology, overall demand for wireless services, competitive pressures
and general economic conditions. In addition, capital spending patterns in the
wireless industry can be subject to some degree of seasonality, with lower
levels of spending in the third calendar quarter, based on annual budget cycles.

COMPETITION IN OUR MARKET MAY LEAD TO REDUCED REVENUES AND OUR MARKET SHARE MAY
DECREASE.

     We expect the market for wireless filter products to become increasingly
competitive. This market is part of the broader market for wireless
infrastructure equipment which is dominated by a number of large companies
including Lucent, Motorola, Ericsson, Nortel, Nokia, Siemens, Alcatel and
others. Our current and potential competitors include conventional radio
frequency filter manufacturers and both established and emerging companies
developing competing technologies. We compete primarily with Conductus, Inc. and
Illinois Superconductor Corporation with respect to our SuperFilter products.

     We also compete with alternative means of enhancing a base station's range
and selectivity such as tower mount and ground mount amplifiers and "smart"
antennas. Tower mount and ground mount amplifiers pass the signal received by
the antenna through a broad low level filter, which then amplifies the signal.
These units are produced by a number of companies, which include most of the
manufacturers of base stations such as Motorola, Lucent, Nortel and Nokia.
Filter manufacturers including Allen Telecom and Celwave also produce these
units. The "smart" antennas allow the antennas to focus more resources on the
signal they are trying to receive to enhance the ability to receive the signal.
Among the companies that produce these systems are Metawave and Arraycom.

     We believe that there are other firms currently engaged in potentially
competitive research on superconducting materials and alternative technologies,
some of which have substantially greater resources than us. These firms could
develop and introduce products comparable or superior to our SuperFilter
products which could have a material adverse effect on our unit sales or gross
margins.

     In addition, we currently license technology to a large company that may
decide to manufacture or design its own filter products instead of purchasing or
licensing our technology. We expect increased competition both from existing
competitors and a number of companies that may enter the wireless communications
market. We believe that base station manufacturers represent the most
significant competitive threat to us. Our ability to compete in the future will
depend in part on a number of competitive factors outside our control, including
the development by others of products that are competitive with our systems and
the price at which others offer comparable products. To be competitive, we will
need to continue to invest substantial resources in engineering, research and
development and sales and marketing. We may not have sufficient resources to
make these investments and we may not be able to make the technological advances
necessary to remain competitive. Accordingly, there can be no assurance that we
will be able to compete successfully in the future.

WE CURRENTLY HAVE NEGATIVE GROSS MARGINS ON OUR SUPERFILTER PRODUCTS AND MUST
INCREASE UNIT SALES TO COVER FIXED MANUFACTURING COSTS.

     We currently have negative gross margins on our SuperFilter products at
current sales levels due to fixed manufacturing costs. In order to achieve
positive gross margins, we must increase units sales to a level sufficient to
cover the fixed manufacturing costs. We do not presently expect to reach this
level until sometime in 2001.

WE EXPECT THAT THE AVERAGE SELLING PRICES OF OUR PRODUCTS WILL DECREASE,
REQUIRING US TO REDUCE OUR COSTS AND INTRODUCE NEW SYSTEMS IN ORDER TO ACHIEVE
AND MAINTAIN PROFITABILITY.

     We anticipate that average selling prices for our products will decrease in
the future in response to competitive pricing pressures and new product
introductions by us and our existing and future competitors. In order to
maintain acceptable gross margins, we will have to reduce the manufacturing
costs of our products through engineering improvements and economies of scale in
production and purchasing. We may not be able to achieve the required cost
savings at a rate needed to keep pace with competitive pricing pressure. If we
fail to achieve this objective, our business may be harmed.

WE MANUFACTURE ALL OF OUR SUPERFILTER PRODUCTS AT OUR FACILITIES, AND IF WE ARE
UNABLE TO INCREASE OUR MANUFACTURING CAPACITY AND MANUFACTURE PRODUCTS OF
SUFFICIENT QUALITY, WE WILL BE UNABLE TO MEET ANTICIPATED DEMAND, WHICH WILL
LIMIT OUR ABILITY TO GROW.

     We currently manufacture all of our SuperFilter products at our facilities
in Santa Barbara, California. If the demand for our products grows, we will need
to increase our internal manufacturing capacity and our materials purchase,
internal testing and quality assurance functions. Any disruptions in product
flow, or the inability to produce key components at a sufficient quality level,
could limit our revenue, adversely affect our customer relationships,
competitive position and reputation and result in additional costs or
cancellation of orders under agreements with our customers. We intend to expand
our manufacturing capacity and in certain instances, subcontract assembly
processes. We may not be successful in identifying subcontractors with adequate
experience or be able to control the quality of systems by these subcontractors
or retain experienced subcontractors on acceptable terms, if at all.

     Due to our lack of experience with large scale operations, we cannot assure
you that we will be able to develop internally, or contract with third parties
for, additional manufacturing capacity on acceptable terms. Our success depends
on our ability to significantly increase our production capacity. If our
facilities or the facilities of our suppliers are incapable of operating, even
temporarily, or are unable to operate at or near full capacity for any extended
period, our business could be harmed. The addition of any facility will likely
increase the complexity of our operations and the risk of inefficient management
of our manufacturing operations. Our manufacturing facilities are vulnerable to
damage or interruption from earthquakes and other natural disasters, power loss,
sabotage, intentional acts of vandalism and similar events. We do not have
earthquake insurance or a formal disaster recovery plan. We also may not carry
sufficient business interruption insurance to compensate us for losses that
could occur during covered disasters. The occurrence of any of these events
could harm our business.

OUR RELIANCE ON A LIMITED NUMBER OF SUPPLIERS AND THE LONG LEAD TIME OF
COMPONENTS FOR OUR SUPERFILTER PRODUCTS COULD IMPAIR OUR ABILITY TO MANUFACTURE
AND DELIVER OUR SYSTEMS ON A TIMELY BASIS.

     We currently purchase substrates for growth of high-temperature
superconductor thin-films from one supplier because of the quality of its
substrates. A thin film is a thin layer of high-temperature superconductor
material. There are additional components that we source from a single vendor
due to the present volume. Our reliance on sole or limited source suppliers
involves certain risks and uncertainties, including the possibility of a
shortage or the discontinuation of certain key components. Any reduced
availability of these parts or components when required could impair our ability
to manufacture and deliver our systems on a timely basis and result in the
cancellation of orders, which could harm our business.

     In addition, the purchase of some of our key components involves long lead
times and, in the event of unanticipated increases in demand for our SuperFilter
products, we may be unable to obtain these components in sufficient quantities
to meet our customers' requirements. We do not have guaranteed supply
arrangements with any of these suppliers, do not maintain an extensive inventory
of parts or components and customarily purchase sole or limited source parts and
components pursuant to purchase orders. Business disruptions, quality issues,
production shortfalls or financial difficulties of a sole or limited source
supplier could materially and adversely affect us by increasing product costs,
or eliminating or delaying the availability of such parts or components. In such
events, our inability to develop alternative sources of supply quickly and on a
cost-effective basis could impair our ability to manufacture and deliver our
systems on a timely basis and could harm our business.

OUR CUSTOMERS ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATION THAT COULD CAUSE
SIGNIFICANT DELAYS IN ORDERS OF OUR PRODUCTS.

     Our customers are primarily wireless telecommunications companies whose
operations are subject to extensive government regulations. We could experience
delays in orders for our products to the extent that our customers are delayed
in deploying their wireless systems as a result of existing or new standards or
regulations. These delays could harm our business.



                                       6
<PAGE>   10




IF WE ARE UNABLE TO FORECAST OUR INVENTORY NEEDS ACCURATELY, WE MAY BE UNABLE TO
OBTAIN EFFICIENT MANUFACTURING CAPACITY OR MAY INCUR UNNECESSARY COSTS AND
OBTAIN EXCESS INVENTORY.

     We use a rolling forecast based on anticipated product orders to determine
our manufacturing requirements. If we overestimate our requirements, our
suppliers may have excess inventory, which would increase our costs. If we
underestimate our requirements, our suppliers may have an inadequate inventory,
which could interrupt manufacturing of our products and result in delays in
shipments and revenues. In addition, lead times for materials and components we
order vary significantly and depend on factors such as the specific supplier,
contract terms and demand for each component at a given time. Accordingly, if we
inaccurately forecast demand for our products, we may be unable to obtain
adequate manufacturing capacity from suppliers to meet our customers' delivery
requirements, which would harm our business.

IF WE ARE UNABLE TO IMPLEMENT APPROPRIATE CONTROLS AND PROCEDURES TO MANAGE OUR
EXPECTED GROWTH, WE MAY NOT BE ABLE TO SUCCESSFULLY OFFER OUR PRODUCTS AND
IMPLEMENT OUR BUSINESS PLAN.

     Our ability to successfully offer our products and implement our business
plan in a rapidly evolving market requires an effective planning and management
process. We have grown our operations and headcount significantly in recent
periods and plan to continue to increase the scope of our operations and
headcount substantially. We added a total of 53 employees during the first nine
months of this year bringing us to a total of 171 employees at September 30,
2000. This growth has placed, and our anticipated growth in future operations
will continue to place, a significant strain on our management systems and
resources. We expect that we will need to continue to improve our financial and
managerial controls, reporting systems and procedures, and will need to continue
to expand, train and manage our work force worldwide. Furthermore, we expect
that we will be required to manage multiple relationships with various customers
and other third parties.

WE RELY ON THE SERVICES OF OUR EXECUTIVE OFFICERS AND OTHER KEY PERSONNEL, WHOSE
KNOWLEDGE OF OUR BUSINESS AND TECHNICAL EXPERTISE WOULD BE EXTREMELY DIFFICULT
TO REPLACE.

     Our future success depends upon the continued services of our executive
officers and other key engineering, sales, marketing and support personnel, both
individually and as a group, whose knowledge of our business and technical
expertise would be extremely difficult to replace. None of our officers or key
employees is bound by an employment agreement for any specific term. Nor do we
have "key person" life insurance policies covering any of our employees. If one
or more members of our senior management team or key technical personnel were
unable or unwilling to continue in their present positions, these individuals
would be very difficult to replace and our business may be harmed.

WE MAY NOT BE ABLE TO HIRE AND RETAIN A SIGNIFICANT NUMBER OF QUALIFIED
ENGINEERS AND SALES AND MARKETING PERSONNEL TO SUSTAIN OUR GROWTH.

     We intend to hire a significant number of engineering, manufacturing and
sales personnel in the future, and we believe our success depends, in large
part, upon our ability to attract and retain these key employees. Competition
for these individuals is intense. In particular, we have experienced difficulty
in hiring qualified engineers, sales personnel and marketing personnel, and we
may not be successful in attracting and retaining these individuals. The
inability to attract or retain qualified personnel in the future, or delays in
hiring required personnel, particularly engineers and sales personnel, could
delay the development and introduction of and negatively impact our ability to
sell our products, which would harm our business.

BECAUSE COMPETITION FOR OUR TARGET EMPLOYEES IS INTENSE, WE MAY BE SUBJECT TO
CLAIMS OF UNFAIR HIRING PRACTICES, TRADE SECRETS MISAPPROPRIATION OR OTHER
RELATED INTELLECTUAL PROPERTY CLAIMS.

     Companies in our industry whose employees accept positions with competitors
frequently claim that their competitors have engaged in unfair hiring practices,
trade secrets misappropriation or other related intellectual property claims. We
cannot assure you that we will not receive such claims in the future as we seek
to hire qualified personnel or that such claims will not result in material
litigation. We could incur substantial costs in defending ourselves against
these claims, regardless of their merits.


                                       7
<PAGE>   11






OUR LIMITED ABILITY TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS MAY HARM OUR
COMPETITIVENESS.

     Our ability to compete and to continue to provide technological innovation
depends substantially upon internally developed technology. We rely on a
combination of patent, copyright, trademark and trade secret laws and
restrictions on disclosure to protect our intellectual property rights in such
technology. To date, we have 27 issued patents in the United States, and 8
patent applications pending in the United States. Patents may not be issued from
these or future applications. Even if they are issued, our patents may not
survive a legal challenge to their validity.

     We also enter into confidentiality agreements with our employees,
consultants, suppliers and licensees and control access to and distribution of
our documentation and other proprietary information. Despite our efforts to
protect our intellectual property rights, unauthorized parties may attempt to
copy or otherwise obtain and use our products or technology. Monitoring
unauthorized use of our products is difficult and we cannot be certain that the
steps we have taken will prevent unauthorized use of our technology,
particularly in foreign countries where the laws may not protect our proprietary
rights as fully as in the United States.

OUR PRODUCTS MAY INFRINGE ON THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES,
WHICH MAY RESULT IN LAWSUITS AND PROHIBIT US FROM SELLING OUR PRODUCTS.

     In recent years, there has been significant litigation in the United States
involving patents and other intellectual property rights. We believe there is a
risk that third parties have filed, or will file applications for, or have
received or will receive, patents or obtain additional intellectual property
rights relating to materials or processes that we use or propose to use.
Although we have never been involved in any intellectual property litigation, we
have received notices in the past from third parties asserting that we have
infringed their intellectual property rights. We may be a party to litigation in
the future to protect our intellectual property or as a result of claimed
infringement of others' intellectual property. These claims and any resulting
lawsuit, if successful, could subject us to significant liability for damages
and invalidation of our patent or other intellectual property rights. These
lawsuits, regardless of their success, would likely be time-consuming and
expensive to resolve and would divert management time and attention. Any
potential intellectual property litigation also could force us to do one or more
of the following:

     o    stop selling, incorporating or using our products that use the
          challenged intellectual property;
     o    obtain from the owner of the infringed intellectual property right a
          license to sell or use the relevant technology, which license may not
          be available on reasonable terms, or at all; or
     o    redesign the products that use the relevant technology.

     If we are forced to take any of these actions, our business may be harmed.
Additionally, we currently do not have liability insurance to protect against
the risk that technology we have licensed from third parties for use in our
business infringes the intellectual property of others.

WE DEPEND ON SPECIFIC PATENTS AND LICENSES TO TECHNOLOGIES, AND WE MAY NEED
ADDITIONAL TECHNOLOGIES IN THE FUTURE THAT WE MAY NOT BE ABLE TO ACCESS.

     We have an exclusive, worldwide license, in all fields of use, to
formulations covered by patents held by the University of Arkansas covering
thallium barium calcium cooper oxide, the material upon which we primarily rely
for our high temperature superconductor products and product development. These
patents may be subject to challenge. Under the terms of our exclusive license,
we agreed to assume litigation expenses for infringement actions, subject to a
right of setoff against future royalty obligations. If we are required to incur
significant expenses under this agreement our business may be harmed. In
addition, we granted DuPont a non-exclusive worldwide sublicense under our
license with the University of Arkansas to develop and market thallium barium
calcium cooper oxide materials and superconducting technologies. The use of
these sublicenses, whether proper or improper, may harm our business. In
addition, other parties may have developed similar materials utilizing thallium
barium calcium cooper oxide formulations and may design around the patented
aspects of this material, resulting in harm to our business. We also have a
non-exclusive license to several patents from SunPower, Inc. relating to our
cooling technology.



                                       8
<PAGE>   12





WE HAVE FOCUSED ON ONE MATERIAL FOR OUR PRODUCT DEVELOPMENT EFFORTS, WHICH MAY
NOT PROVE COMPETITIVE AGAINST OTHER MATERIALS.

     To date, we have principally focused our development efforts on thallium
barium calcium cooper oxide. Although thallium barium calcium cooper oxide has
one of the highest critical temperatures of any high-temperature superconductor
material verified by the scientific community to date, other materials are
currently known to have advantages over thallium barium calcium cooper oxide for
some applications. Thallium barium calcium cooper oxide may not ultimately prove
commercially competitive against yttrium barium cooper oxide or against other
currently known materials. Furthermore, other materials may be discovered with
higher critical temperatures or other superior qualities, and we may not be able
to obtain the rights to those superior materials.

WE ANTICIPATE THAT SALES TO CUSTOMERS BASED OUTSIDE THE UNITED STATES WILL
ACCOUNT FOR A SIGNIFICANT PORTION OF OUR NET REVENUES IN FUTURE PERIODS, WHICH
EXPOSES US TO RISKS INHERENT IN INTERNATIONAL OPERATIONS.

     During 1999, we began to market our products internationally. While
international sales have not represented a significant percentage of gross
commercial product revenues to date, we believe that international sales
represent a significant opportunity for future growth. International operations
are subject to inherent risks, including:

     o    greater difficulty in accounts receivable collection and longer
          collection periods;
     o    difficulties and costs of staffing and managing foreign operations;
     o    the impact of recessions in economies outside the United States;
     o    unexpected changes in regulatory requirements;
     o    certification requirements;
     o    reduced protection for intellectual property rights in some countries;
     o    potentially adverse tax consequences;
     o    political and economic instability; and
     o    foreign currency fluctuations.

     Our international revenue is currently denominated in U.S. dollars. As a
result, fluctuations in the value of the U.S. dollar and foreign currencies may
make our products more expensive to international customers, which could harm
our potential growth. We do not currently engage in currency hedging activities
to limit the risk of exchange rate fluctuations but may consider such activities
if our international revenues increase significantly.

NECESSARY LICENSES OF THIRD PARTY TECHNOLOGY MAY NOT BE AVAILABLE TO US, OR MAY
BE VERY EXPENSIVE.

     We depend upon licensed technology to manufacture our SuperFilter products.
Specifically, we currently depend upon licenses obtained from Sun Power and the
University of Arkansas. From time to time, we may be required to license further
technology from third parties to develop new products or product enhancements.
We cannot assure you that the technology we license from SunPower and the
University of Arkansas will continue to be available to us. Further, we cannot
assure you that third party licenses will be available to us on commercially
reasonable terms, if at all. The inability to obtain any third-party license
required to develop new products and product enhancements could require us to
obtain substitute technology of lower quality or performance standards or at
greater cost, either of which could seriously harm our business financial
condition and results of operations.

IF WE ACQUIRE ANY COMPANIES OR TECHNOLOGIES IN THE FUTURE, THEY COULD PROVE
DIFFICULT TO INTEGRATE, DISRUPT OUR BUSINESS, DILUTE STOCKHOLDER VALUE AND
ADVERSELY AFFECT OUR OPERATING RESULTS.

     We may acquire or make investments in complementary companies, services and
technologies in the future. We have not made any acquisitions or investments to
date and, therefore, our ability as an organization to make acquisitions or
investments is unproven.

     Acquisitions and investments involve numerous risks, including:

     o    difficulties in integrating operations, technologies, services and
          personnel;
     o    diversion of financial and management resources from existing
          operations;
     o    risk of entering new markets;

                                       9
<PAGE>   13





     o    potential loss of key employees; and
     o    inability to generate sufficient revenues to offset acquisition or
          investment costs.

     In addition, future acquisitions could result in potentially dilutive
issuances of equity securities, or the incurrence of debt, contingent
liabilities or amortization expenses related to goodwill or other intangible
assets, any of which could harm our business. As a result, if we fail to
properly evaluate and execute acquisitions or investments, our business and
prospects may be seriously harmed.

RISKS RELATED TO RESEARCH AND DEVELOPMENT CONTRACTING BUSINESS

WE ARE DEPENDENT ON GOVERNMENT CONTRACTS FOR A LARGE PERCENTAGE OF OUR REVENUE
AND A SHIFT IN THE BUDGETARY PRIORITIES OF THE U. S. GOVERNMENT COULD ADVERSELY
AFFECT OUR REVENUES.

     Until recently, we have derived most of our revenues from contracts funded
by agencies of the U.S. Government, in particular the Department of Defense.
Contracts or subcontracts funded by the Department of Defense accounted for
approximately 97%, 76% and 71% of our revenue during the years ended December
31, 1997, 1998 and 1999, respectively, and 58% for the six months ended July 1,
2000. If the U.S. government decreased its spending on research and development
projects such as ours, our business could suffer. Additionally, while many of
our government contracts extend over several years, such contracts are typically
funded for no more than one year at a time. If the government modifies or
terminates our government contracts, our business may be harmed.

WE FACE INTENSE COMPETITION IN OBTAINING GOVERNMENT CONTRACTS.

     The market for research and development projects is competitive and is
characterized by rapid technological change, developments and advancements. Many
of our competitors have substantially greater resources and name recognition
than we do. We cannot assure you that our competitors will not develop new
technologies or introduce new solutions that will offer superior pricing or
performance features or that new solutions or technologies will not impair the
competitiveness of our solutions.

WE ARE SUBJECT TO GOVERNMENT AUDITS OF OUR CONTRACT COSTS AND ANY ADJUSTMENTS TO
THESE COSTS COULD RESULT IN DECREASED REVENUES AND NET INCOME.

     All costs for services under our government contracts are subject to audit,
and the acceptance of such costs as allowable and allocable is subject to
federal regulatory guidelines. We record contract revenues in amounts which we
expect to be realized upon final audit settlement. Any disallowance of costs by
the government could have an adverse effect on our business, operating results
and financial condition. We cannot assure you that audits and adjustments will
not result in decreased revenues and net income for those years. Additionally,
because of our participation in government contracts, we are subject to audit
from time to time for our compliance with government regulations by various
agencies. Government agencies may conduct inquiries or investigations that may
cover a broad range of our activity. Responding to any such audits, inquiries or
investigations may involve significant expense and divert management attention.
In addition, an adverse finding in any such audit, inquiry or investigation
could involve penalties that may harm our business.

OUR GOVERNMENT CONTRACTS ARE SUBJECT TO COMPLEX APPROVAL PROCESSES WHICH COULD
RESULT IN A LONGER SALES CYCLE AND A DELAY IN REVENUE RECOGNITION CAUSING OUR
QUARTERLY OPERATING RESULTS TO FLUCTUATE.

     The majority of our existing customers are government agencies which often
have complex and time-consuming approval processes. The period between initial
discussions concerning a particular project and the customer's purchase
commitment typically ranges from six to twelve months. These delays could harm
our business and, in particular, could cause fluctuations in our operating
results on a quarterly basis.

RISKS RELATED TO OUR STOCK

WE MAY NEED TO RAISE ADDITIONAL CAPITAL IN THE FUTURE.

     As of July 1, 2000, we had cash and cash equivalents of $4.5 million. As
discussed in the next paragraph, we subsequently received a $37.5 million
private equity investment from the selling stockholder named in this prospectus.
We now expect our existing cash resources, together with our line of credit and
anticipated cash flow from operations, to be sufficient to meet our working
capital and capital expenditure needs beyond the next year. However, we may
ultimately need additional debt or equity financing to fully implement our
business plan and achieve profitability. We may also require additional capital
to acquire or invest in complementary businesses or products or obtain the right
to use complementary technologies. If we cannot raise any needed funds on
acceptable terms, it will harm our business. If we issue additional equity
securities to raise funds, the ownership percentage of our existing stockholders
would be reduced. New investors may demand rights, preferences or privileges
senior to those of existing holders of common stock.

COMMON STOCKHOLDERS MAY SUFFER DILUTION DUE TO THE FLOATING CONVERSION PRICE OF
THE SERIES E PREFERRED STOCK AND THE ANTIDILUTION PROVISIONS OF THE WARRANTS
ISSUED TO THE ORIGINAL PURCHASERS OF THE PREFERRED STOCK.

     We issued 37,500 shares of our Series E Preferred Stock to the selling
stockholder named in this prospectus. The preferred stock has a stated value of
$1,000 per share and is convertible into common stock at an initial conversion
price of $17.95 per common share until June 29, 2001. After that date, the
preferred stock is convertible at the lower of $17.95 per common share or the
market price of the common stock at the time of conversion, subject to a floor.
Any remaining unconverted preferred stock automatically converts into common
stock on September 29, 2002. Based on the current conversion price of $17.95 per
common share, the preferred stock is presently convertible into 2,089,136 shares
of common stock. This number of shares could significantly increase in the event
of a decrease in the trading price of the common stock, but the maximum issuable
upon optional and automatic conversions of the preferred stock is 3,544,656
shares of common stock. The existing holders of common stock could therefore
experience further dilution depending on the market price of our common stock
with respect to conversions of the Series E Preferred Stock after June 29, 2001.

     The Company also issued five-year warrants to purchase 1,044,568 shares of
common stock to the original purchaser of the Series E Preferred Stock. These
warrants have an exercise price of $21.54 per share of common stock, but the
warrants contain "weighted average" antidilution provisions which adjust the
warrant exercise price and the number of shares in the event the Company sells
equity securities at a discount to then prevailing market prices. The amount of
the adjustment depends on the size of the below-market transaction and the
amount of the discount to the market price. The antidilution adjustments for
below-market transactions cannot reduce the exercise price below a minimum of
$18.91 per share. The existing holders of common stock could therefore
experience further dilution in the event the Company sells equity securities at
a discount to then prevailing market prices.

PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY MAKE IT DIFFICULT FOR A
THIRD PARTY TO ACQUIRE US AND COULD CAUSE THE PRICE OF OUR COMMON STOCK TO
DECLINE.

     Provisions of our Restated Certificate of Incorporation, our Bylaws and
Delaware law could make it more difficult for a third party to acquire us, even
if doing so would be beneficial to our stockholders. These provisions could also
discourage proxy contests and make it more difficult for you and other
stockholders to elect directors and take other corporate actions. As a result,
these provisions could limit the price that investors are willing to pay in the
future for shares of our common stock.

FUTURE SALES OF OUR COMMON STOCK COULD CAUSE OUR STOCK PRICE TO DECLINE.

     Sales of a substantial number of our common shares in the public market
could cause the market price of our common stock to decline. This prospectus
covers up to 5,121,508 shares of common stock potentially issuable upon
conversion of the Series E Preferred Stock and exercise of the related warrants
issued in connection with the Series E Preferred Stock. As of September 30,
2000, we had outstanding options to purchase 1,848,363 shares of common stock
outstanding under our employee stock option plans and warrants to purchase up to
another 2,168,093 shares.


                                       11
<PAGE>   15




The shares issuable upon option exercises are freely tradable. The shares
issuable upon warrant exercises are restricted, but the warrant holders have
certain registration rights.

OUR STOCK PRICE IS EXTREMELY VOLATILE, AND YOU MAY NOT BE ABLE TO RESELL YOUR
SHARES AT OR ABOVE THE PRICE PAID.

     The trading price of our common stock has fluctuated significantly in
recent periods, and it is likely that it will continue to be volatile. It is
possible that the price of the common stock will decline below the price paid by
you, and that you would lose all or part of your investment. Equity markets,
particularly for technology companies, have recently experienced significant
price and volume fluctuations that are unrelated to the operating performance of
individual companies. These broad market fluctuations may cause the market price
of our common stock to decline.

OUR NET OPERATING LOSS CARRYFORWARDS COULD BE REDUCED IF THERE IS A "CHANGE OF
OWNERSHIP" UNDER SECTION 382 OF THE INTERNAL REVENUE CODE.

     We had federal net operating loss carryforwards of approximately $37
million at December 31, 1999. Section 382 of the Internal Revenue Code imposes
an annual limitation on the utilization of net operating loss carryforwards
based on a statutory rate of return (usually the "applicable federal rate," as
defined in the Internal Revenue Code) and the value of the corporation at the
time of a "change of ownership" as defined by Section 382. We are currently
evaluating the circumstances under which the exercise of our outstanding
warrants and options, combined with our private stock sales over the last few
years, may trigger a "change in ownership" under Section 382. If this were to
occur, it could significantly diminish the value of our net operating loss
carryforwards by limiting the rate at which we would be permitted to offset them
against any future taxable income.

WE ARE AT A RISK OF SECURITIES CLASS ACTION LITIGATION DUE TO OUR EXPECTED STOCK
PRICE VOLATILITY.

     In the past, securities class action litigation has often been brought
against a company following periods of volatility in the market price of its
securities. We may in the future be the target of similar litigation. Securities
litigation could result in substantial costs and divert management's attention
and resources, which could harm our business.

YOU MAY INCUR IMMEDIATE AND SUBSTANTIAL DILUTION IN THE BOOK VALUE PER SHARE OF
COMMON STOCK BECAUSE THE MARKET PRICE OF OUR STOCK IS SUBSTANTIALLY HIGHER THAN
ITS BOOK VALUE.

     Our common stock had a book value of $0.79 per share as of July 1, 2000.
The closing sale price of our common stock on the Nasdaq National Market was
$11.5625 per share on October 20, 2000. In light of the current discrepancy
between the book and market value of our common stock, you may incur immediate
and substantial dilution in the book value per share from the price you pay for
the common stock.

CHANGES TO FINANCIAL ACCOUNTING STANDARDS MAY AFFECT OUR REPORTED RESULTS OF
OPERATIONS.

     We prepare our financial statements to conform to generally accepted
accounting principles, or GAAP. These accounting principles are subject to
interpretation by the American Institute of Certified Public Accountants, the
SEC and various bodies formed to interpret and create appropriate accounting
policies. A change in those policies can have a significant effect on our
reported results and may even affect our reporting of transactions completed
before a change is announced. Accounting policies affecting many other aspects
of our business, including rules relating to purchase and pooling-of-interests
accounting for business combinations, employee stock option grants and revenue
recognition have recently been revised or are under review. Changes to those
rules or the questioning of current practices may adversely affect our reported
financial results or on the way we conduct our business. In addition, our
preparation of financial statement in accordance with GAAP requires that we make
estimates and assumptions that affect the recorded amounts of assets and
liabilities, disclosure of those assets and liabilities at the date of the
financial statements and the recorded amounts of expenses during the reporting
period. A change in the facts and circumstances surrounding those estimates
could result in a change to our estimates and could harm our business.

THE RELIABILITY OF MARKET DATA INCLUDED IN OUR PUBLIC FILINGS IS UNCERTAIN.

     Since we are relatively new to the commercial market and operate in a
rapidly changing market, we have in the past, and may from time to time in the
future, include market data from industry publications in some of the documents
filed with the Securities Exchange Commission and incorporated by reference into
this prospectus. The reliability of this data cannot be assured. The market data
and information incorporated by reference into this prospectus was obtained from
internal company surveys and industry publications. Industry publications
generally state that the information contained in these publications has been
obtained from sources believed to be reliable, but that its accuracy and

                                 USE OF PROCEEDS

     We will not directly receive any proceeds from the sale of shares under
this prospectus. We may indirectly receive proceeds of up to approximately $22.5
million to the extent that the selling stockholder exercises warrants to acquire
shares of common stock for resale under this prospectus. The actual amount of
any proceeds will equal the number of shares purchased multiplied by the
exercise price of the warrants exercised. We will use any proceeds from the
exercise of warrants for general corporate purposes.

                               SELLING STOCKHOLDER

SELLING STOCKHOLDER TABLE

     The selling stockholder acquired shares of our Series E Preferred Stock and
related warrants from us in a private placement on September 29, 2000. This
prospectus covers the resale by the selling stockholder of the shares of our
common stock which are issuable upon conversion of the preferred stock and upon
exercise of the warrants. This prospectus does not cover the initial issuance of
the shares of preferred stock or warrants to the selling stockholder nor the
resale of those securities to any third party.

     The following table sets forth the number of shares of common stock
beneficially owned by the selling stockholder as of October 12, 2000.

</TABLE>

-------------------

(1)  This number consists of 2,089,136 shares of common stock presently issuable
     upon conversion of the preferred stock held by the selling stockholder and
     1,044,568 shares of common stock presently issuable upon exercise of the
     warrants held by the selling stockholder.
(2)  This number consists of 3,554,656 shares of common stock relating to the
     preferred stock and 1,566,852 shares of common stock relating to the
     warrants. We are contractually required to register this number of shares
     under our agreement with the selling stockholder, and it constitutes more
     shares of common stock than are currently issuable to the selling
     stockholder upon conversion of the preferred stock and exercise of the
     warrants. This is due to two factors. First, the conversion price of the
     preferred stock varies with the market price of our common stock after June
     29, 2001, potentially increasing the number of shares issuable upon
     conversion of the preferred stock if our stock price declines below $17.95
     per share. However, this feature of the preferred stock is subject to a
     floor, and the maximum number of shares issuable upon optional and
     mandatory conversion of the preferred stock is 3,554,656 shares of common
     stock. Second, the warrants contain "weighted average" antidilution
     provisions which adjust the warrant exercise price and the number of shares
     issuable upon exercise of the warrant in the event that we sell equity
     securities at a discount to then prevailing market prices. In contemplation
     of this possibility, our registration rights agreement with the selling
     stockholder requires that we register 150% of the aggregate number of
     shares currently issuable upon exercise of the warrants to cover additional
     shares resulting from potential future antidilution adjustments. In
     addition to the shares set forth in the table, the amount to be registered
     includes an indeterminate number of shares issuable upon conversion of or
     in respect of the Series E Convertible Preferred Stock and the warrants, as
     such number may be adjusted as a result of stock splits, stock dividends
     and similar transactions in accordance with Rule 416.
(3)  Under the terms of the Series E Preferred Stock and the related warrants,
     the shares of Series E Preferred Stock are convertible and the warrants are
     exercisable by any holder only to the extent that the number of shares of
     common stock issuable pursuant to such securities, together with the number
     of shares of common stock owned by such holder and its affiliates (but not
     including shares of common stock underlying unconverted shares of Series E
     Preferred Stock or unexercised portions of the warrants) would not exceed
     4.9% of the then outstanding common stock as determined in accordance with
     Section 13(d) of the Exchange Act. Accordingly, the number of shares of
     common stock set forth in the table for RGC International Investors exceeds
     the number of shares of common stock that RGC International Investors could
     own beneficially at any given time through their ownership of the Series E
     Preferred Stock and the warrants. In that regard, the beneficial ownership
     of the common stock by RGC International Investors set forth in the table
     is not determined in accordance with Rule 13d-3 under the Exchange Act.

CERTAIN INFORMATION ABOUT THE SELLING STOCKHOLDER

     The actual number of shares of common stock issuable upon conversion of the
Series E Preferred Stock is subject to adjustment up to specified maximums and
could be materially less than the maximum number depending on factors which
cannot be predicted by us at this time, including, among other factors, the
future market price of the common stock. The actual number of shares of common
stock offered in this prospectus, and included in the registration statement of
which this prospectus is a part, includes such additional number of shares of
common stock as may be issued or issuable upon conversion of the Series E
Preferred Stock and exercise of the related warrants by


                                       14
<PAGE>   18





reason of any stock split, stock dividend or similar transaction involving the
common stock, in accordance with Rule 416 under the Securities Act.

     As of October 24, 2000, the Series E Preferred Stock was convertible into
2,089,136 shares of common stock at a conversion price of $17.95 per share.
After June 29, 2001, the conversion price of the preferred stock varies with the
market price of our common stock, potentially increasing the number of shares
issuable upon conversion of the preferred stock if our stock price declines
below $17.95 per share. However, this feature of the preferred stock is subject
to a floor, and the maximum the number of shares issuable upon optional and
mandatory conversion of the preferred stock is 3,554,656 shares of common stock.

     The related warrants are exercisable for 1,044,568 shares of common stock
at an exercise price of $21.54 per share. The warrants contain "weighted
average" antidilution provisions which adjust the warrant exercise price and the
number of shares issuable upon exercise of the warrant in the event that we sell
equity securities at a discount to then prevailing market prices. The warrants
contain a limit on the exercise price adjustment for below-market stock
issuances to a minimum exercise price of $18.91 per share.

                              PLAN OF DISTRIBUTION

     The shares being offered by the selling stockholder or its respective
pledgees, donees, transferees or other successors in interest, will be sold from
time to time in one or more transactions, which may involve block transactions:

     o    on the Nasdaq National Market or on such other market on which the
          common stock may from time to time be trading;
     o    in privately-negotiated transactions;
     o    through the writing of options on the shares;
     o    short sales; or
     o    any combination thereof.

     The sale price to the public may be:

     o    the market price prevailing at the time of sale;
     o    a price related to such prevailing market price;
     o    at negotiated prices; or
     o    such other price as the selling stockholder determines from time to
          time.

     The shares may also be sold pursuant to Rule 144. The selling stockholder
shall have the sole and absolute discretion not to accept any purchase offer or
make any sale of shares if it deems the purchase price to be unsatisfactory at
any particular time.

     The selling stockholder or its respective pledgees, donees, transferees or
other successors in interest, may also sell the shares directly to market makers
acting as principals and/or broker-dealers acting as agents for themselves or
their customers. Such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the selling stockholder and/or the
purchasers of shares for whom such broker-dealers may act as agents or to whom
they sell as principal or both, which compensation as to a particular
broker-dealer might be in excess of customary commissions. Market makers and
block purchasers purchasing the shares will do so for their own account and at
their own risk. It is possible that the selling stockholder will attempt to sell
shares of common stock in block transactions to market makers or other
purchasers at a price per share which may be below the then market price. The
selling stockholder cannot assure that all or any of the shares offered in this
prospectus will be sold by the selling stockholder. The selling stockholder and
any brokers, dealers or agents, upon effecting the sale of any of the shares
offered in this prospectus, may be deemed "underwriters" as that term is defined
under the Securities Act or the Exchange Act, or the rules and regulations under
such acts.

     The selling stockholder, alternatively, may sell all or any part of the
shares offered in this prospectus through an underwriter. The selling
stockholder has not entered into any agreement with a prospective underwriter

                                       15
<PAGE>   19





and there is no assurance that any such agreement will be entered into. If the
selling stockholder enters into such an agreement or agreements, the relevant
details will be set forth in a supplement or revisions to this prospectus.

     The selling stockholder and any other persons participating in the sale or
distribution of the shares will be subject to applicable provisions of the
Exchange Act and the rules and regulations under such act, including, without
limitation, Regulation M. These provisions may restrict certain activities of,
and limit the timing of purchases and sales of any of the shares by, the selling
stockholder or any other such person. Furthermore, under Regulation M, persons
engaged in a distribution of securities are prohibited form simultaneously
engaging in market making and certain other activities with respect to such
securities for a specified period of time prior to the commencement of such
distributions, subject to specified exceptions or exemptions. All of these
limitations may affect the marketability of the shares covered by this
prospectus.

     We have agreed to indemnify the selling stockholder, or its transferees or
assignees, against certain liabilities, including liabilities under the
Securities Act, or to contribute to payments the selling stockholder or its
respective pledgees, donees, transferees or other successors in interest, may be
required to make in respect of such liabilities.

     We are paying the cost of registering the shares of common stock to which
this prospectus relates as well as various related expenses. The selling
stockholder is responsible for all selling commissions, transfer taxes and other
costs related to the offer and sale of their shares.

     We have agreed to use best efforts to keep the Registration Statement (of
which this prospectus forms a part) effective until the selling stockholder has
sold all of its shares or until the shares may be immediately sold to the public
without registration or restriction (including without limitation as to volume
by each holder thereof) under the Securities Act.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware Law General Corporation (the "Delaware Law")
provides that a corporation may indemnify directors and officers as well as
other employees and individuals against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement in connection with specified
actions, suits or proceedings, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation -- a
"derivative action"), if they acted in good faith and in a manner they
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe their conduct was unlawful. A similar standard is
applicable in the case of derivative actions, except that indemnification only
extends to expenses (including attorneys' fees) incurred in connection with
defense or settlement of such action, and the statute requires court approval
before there can be any indemnification where the person seeking indemnification
has been found liable to the corporation. Under Section 145, a corporation shall
indemnify an agent of the corporation for expenses actually and reasonably
incurred if and to the extent such person was successful on the merits in a
proceeding or in defense of any claim, issue or matter therein.

     The Company may from time to time be subject to Section 2115 of the
California Corporations Code (the "California Code"), according to which Section
317 of the California Code applies to the indemnification of officers and
directors of the Registrant. Under Section 317 of the California Code,
permissible indemnification by a corporation of its officers and directors is
substantially the same as permissible indemnification under Section 145 of the
Delaware Law, except that (i) permissible indemnification does not cover actions
the person reasonably believed were not opposed to the best interests of the
corporation, as opposed to those the person believed were in fact in the best
interests of the corporation, (ii) the Delaware Law permits advancement of
expenses to agents other than officers and directors only upon approval of the
board of directors, (iii) in a case of stockholder approval of indemnification,
the California Code requires certain minimum votes in favor of such
indemnification and excludes the vote of the potentially indemnified person, and
(iv) the California Code only permits independent counsel to approve
indemnification if an independent quorum of directors is not obtainable, while
the Delaware Law permits the directors in any circumstances to appoint counsel
to undertake such determination.

     Section 145 of the Delaware Law and Section 317 of the California Code
provide that they are not exclusive of other indemnification that may be granted
by a corporation's charter, bylaws, disinterested director vote, stockholder
vote, agreement or otherwise. The limitation of liability contained in the
Company's Certificate of Incorporation and the indemnification provision
included in the Company's bylaws are consistent with Delaware Law Sections
102(b)(7) and 145 and California Code Section 317. The Company has purchased
directors and officers liability insurance.


                                      II-1
<PAGE>   22


     Section 145 of the Delaware Law authorizes a court to award, or a
corporation's board of directors to grant, indemnity to directors and officers
in terms sufficiently broad to permit such indemnification under certain
circumstances for liabilities (including reimbursement for expenses incurred)
arising under the Securities Act of 1933. The Company's Certificate of
Incorporation and the Company's Bylaws provide for indemnification of its
directors, officers, employees and other agents to the maximum extent permitted
by the Delaware Law. In addition, the Company has entered into indemnification
agreements with its officers and directors.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers or persons controlling the
Company pursuant to such provisions, the Company has been informed that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in such Act and is therefore unenforceable.

ITEM 16.  EXHIBITS

     See Index to Exhibits at page II-6.

ITEM 17.  UNDERTAKINGS

(a)  Rule 415 Offering. The undersigned registrant hereby undertakes:

     (1)  To file, during any period in which offers or sales are being made, a
          post-effective amendment to this Registration Statement:

          (i)   To include any prospectus required by section 10(a)(3) of the
                Securities Act;

          (ii)  To reflect in the prospectus any facts or events arising after
                the effective date of this Registration Statement (or the most
                recent post-effective amendment thereof) which, individually or
                in the aggregate, represent a fundamental change in the
                information set forth in this Registration Statement;

          (iii) To include any material information with respect to the plan of
                distribution not previously disclosed in this Registration
                Statement or any material change to such information in this
                Registration Statement;

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

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

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

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

(c)  Request for Acceleration of Effective Date. Insofar as indemnification for
     liabilities arising under the


                                      II-2
<PAGE>   23






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