Item 1. Description of Business

General

     The Company's core business for over twenty years has been primarily the
design, manufacture and marketing of automated continuous monitoring instruments
used to detect and measure various types of air pollution, such as "acid rain,"
"ozone depletion" and "smog episodes," through its wholly-owned subsidiary,
Dasibi Environmental Corp. The Company's products are generally used to measure
air pollution levels in geographic areas which range in size from small
industrial sites to entire states or countries. The Company also supplies
computer-controlled calibration systems that verify the accuracy of its
instruments, data loggers to collect and manage pollutant information and final
reporting software for remote centralized applications, which is classified as
"core business related." Currently, the Company's primary market focus for its
core business is The People's Republic of China. See "History of the Company and
Recent Developments."

History of the Company and Recent Developments

     The Company was organized as a California corporation on December 24, 1971,
under the name of "A.E. Gosselin Engineering, Inc." as a wholly-owned subsidiary
of "Pollution Research and Control Corp." ("PRCC"), a California corporation
co-founded in 1966 by Albert E. Gosselin, Jr., the Company's President and Chief
Executive Officer, and his wife, Barbara Gosselin, an executive officer and
director of the Company. Mr. and Mrs. Gosselin founded the Company to design,
manufacture and market air pollution monitoring equipment for ambient air (i.e.,
the surrounding air) as distinguished from the customer stack source monitoring
systems then being designed, manufactured and sold by PRCC. The name of the
Company was changed to "Dasibi Environmental Corp." on March 22, 1973.

     The Company was operated as a wholly-owned subsidiary of PRCC until its
initial public offering of securities in May 1985. In 1984, PRCC discontinued
its research and development activities and assigned them to the Company. From
1984 through May 1985, PRCC acted primarily as a holding company for the Company
and Applied Conservation Technology, Inc. ("ACT"), then a wholly-owned
subsidiary of PRCC engaged in the business of providing environmental impact
reports to electric utilities. ACT was purchased by its management from PRCC in
November 1986. Gary Dudley, a director and former Vice President of the Company
and a former executive officer and director of PRCC, has been the President and
a principal shareholder of ACT, a diversified environmental consulting firm now
located in Westminster, California, since November 1986. (See Item 9.
"Directors, Executive Officers, Promoters and Control Persons; Compliance with
Section 16(a) of the Exchange Act - Directors, Executive Officers and Key
Employees.")

     The Company changed its name to "Pollution Research and Control Corp.," the
name of its former parent, PRCC, in November 1989. In January 1990, the Company
acquired all of the issued and outstanding shares of Common Stock, $1.00 par
value per share, of an inactive California corporation, organized by Mr. and
Mrs. Gosselin as co-founders under the name of "Baral Engineering, Inc." in July
1976, which changed its name to "Dasibi Environmental Corp." ("Dasibi") in
January 1990. All of the Company's operations were transferred to Dasibi
subsequent to the acquisition. Also in 1990, the Company changed its fiscal year
from June 30 to December 31.


                                        4


<PAGE>

     In January, 1998, the Company began a reorganization program. The Company's
management believed that it could secure long-term contractual business in The
People's Republic of China ("China") sufficient to allow expansion of the
Company's business independent of competitive price pressures which have been
experienced since 1994 (see "Instrument Market" under this Item 1).

     In June 1998, the Company signed a $5.1 million dollar contract with China
to supply air monitoring equipment and software in integrated systems to
monitor, report, and predict on local regions the air pollutant levels in an
eleven city network designated as Phase I and related to a China monitoring plan
for over 600 cities. The effective starting date was coincident with the
Company's arrangement of U.S. Bank and Export-Import (Ex-Im) guarantee for
financing which occurred in June 1999. A multitude of "firsts" or learning steps
for all parties involved contributed to the length of the financing period.
During this time, in March, 1999 the Company signed a letter of intent in
Beijing, China with The State Environmental Protection Agency for Phase II , an
additional 20 to 25 cities including expansion of the network of the eleven
cities of Phase I.

     An indicated date for the contract signing of Phase II is April, 2000 and
at this time appears likely. Since the Company has chosen to focus primarily on
the China market, it is vital that a continuous flow of business be obtained. To
date, this has not been the case and a need for a high level of staffing
continuously has contributed to a profit and loss "checkerboard" pattern.
Management believes that award of Phase II with such potential side effects as
position for future phases and possible joint venture projects in China would
allow continuous profitable operation. Loss of Phase II would have a material
adverse effect on the Company.

The Air Pollution Industry

     Air pollution consist of certain gases or particles, generally the products
of combustion or other industrial processes, which are or may be hazardous to
human health. Pollutants include carbon monoxide, ozone, oxides of sulfur and
nitrogen, hydrogen sulfide and particles. Small amounts of these pollutants,
such as a few parts per million or part per billion, may be harmful. The
instruments produced and sold by the Company, the "core business" detect and
measure these pollutants and are also utilized in calibrating other pollution
measurement equipment. Any systems or processes such as the Company's "flue gas
purification system" patent employ chemical and mechanical means to remove these
same pollutants from combustion exhaust gases. (See "Research and Development"
under this Item 1. "Description of Business").

     Industrial entities require equipment to detect the presence and measure
the level of pollutants in order to comply with governmental regulations and
government regulatory agencies require equipment to enforce governmental
standards. Currently, international priority has been given to control (and
therefore to monitor) such gaseous pollutants as sulfur dioxide, oxides of
nitrogen, carbon monoxide, ozone and particulates (suspended dust).

     Although manual sampling of both gases and particulates is still performed
routinely, improvements in the reliability and accuracy of automated, continuous
monitoring equipment, such as that manufactured and sold by the Company, have
made manual sampling less desirable and automated monitoring increasingly
common.
                                        5


<PAGE>


     In basic continuous monitoring instruments, ambient air is taken into a
manifold, the function of which is to direct a fast-moving stream of ambient air
to the monitor. The instrument may use a filter to remove particulates or
scrubbers to remove gasses that might interfere with accurate measurement of the
pollutant. The pollutant is then introduced into a measurement cell environment
where it undergoes a chemical or physical reaction, the output of which can be
converted to an electrical signal which, in turn, can be read locally or
transmitted to some remote monitoring plant or computer. Measurement cells can
be based in many different methods for the detection of the pollutants of
interest. Thus, an instrument designer may have many different methods available
by which a pollutant may be identified and measured.

     Some methods used by the Company are flame photometry (wherein
concentrations of gaseous elements are measured by burning them and optically
observing the color and intensity of the flame generated thereby), infrared
absorption (wherein concentrations of infrared absorbing gases are measured by
detecting changes in intensity of a radiation beam closed cell),
chemiluminescence (wherein a chemical generates a light or a wave length
measurable by a photo multiplier tube), ultraviolet spectroscopy (wherein the
pollutants' decrease in ultraviolet light intensity is converted by a
photoelectric detector to an electric signal) and beta ray attenuation (wherein
a radioactive source's beta ray emanation is reduced in direct proportion to the
mass of a particle).

Instrument Market

     The air pollution monitoring equipment market includes two markets: (i)
source instrumentation for monitoring the source's pollutant emissions as they
are discharged into the air and (ii) ambient air for instrumentation for
monitoring ambient air pollution. The two markets are quite different in that
source instrumentation is generally not subject to rigid governmental-imposed
guidelines because of the difficult analyses involved, while ambient air
instruments are subject to rigid governmental guidelines because the pollutants
are easier to define and measure. Since 1994, the ambient market worldwide
except for China, India, and the Philippines has approached saturation with
extremely competitive bid situations which have significantly impacted gross
profit margins. Since 1994, the Company has focused a majority of its world-
wide marketing budget and effort to China, for cost efficient effect to improve
gross profit margin. In 1998, the Company directed its entire marketing effort
to China.

     Generally, the Company sells its instruments for use in systems for the
measurement of ambient air pollution. In a system, air pollution monitoring
instruments are united with additional equipment to provide a comprehensive
measurement unit. In an ambient air instrumentation system, the monitoring
instrument is combined with a manifold intake, a calibrator and data
transmitters. The system samples the ambient air, measure the pollutants and
transmits the data. The Company designs and manufactures all instruments used in
a system, including the data tabulation and transmission devices.

Control Market

     The air pollution control market makes only minimal use of measurement
instrumentation. This market is concerned with "purification" of exhaust gases
emanating from combustion-related or even chemical-only processes. The

                                        6


<PAGE>


"purification" process consists of using various types of equipment which may or
may not involve catalysts and/or reagents to cause reactions and/or mechanical
removal of a high percentage of selected air pollutants. The highest percentage
obtainable will relate, at any given time, to the state-of-the-art of the
technology involved and the economics of implementing the technology. The market
is old, in essence dating to the beginnings of the industry when soot collectors
were first installed on combustion chambers. However, the market size is
embryonic since technology has not materially advanced and implementation
remains costly so as not to allow any generally accepted control of source
pollutants. The Company filed a patent application in April 1994 for a "flue gas
purification system," which issued in 1996, and a second patent issued on the
system in March, 1999, however, the commercial viability of a market for this
invention is not assured. (See "Research and Development" and "Intellectual
Property" under this Item 1. "Description of Business.")

Governmental Approval

     The Environmental Protection Agency (the "EPA") administers the federal
Clean Air Act, as amended by the Clean Air Act Amendments of 1990, and approves
ambient air pollution monitoring equipment meeting certain requirements as
either reference or equivalent methods for measuring pollutants. The EPA
established the reference method as the basic method for measuring a pollutant.
An equivalent method measures the same pollutant utilizing a different technique
which achieves results identical to those of the referenced method.

     As a practical matter, before a monitoring instrument can be sold in the
United States, it must receive EPA-approval as either a "reference" or
"equivalent" method. Such approvals are given only after rigorous and expensive
testing by the applicant and the submission to, and approval by, the EPA of the
results of such testing. The testing and approval process generally requires
between 12 and 18 months. Following approval, the EPA typically acquires and
tests a production model of the device. If the model being tested does not meet
the standards established by the approval process, the approval may be
withdrawn.

     Each of the Company's models of ozone monitors and its sulfur dioxide and
oxides of nitrogen monitors have been approved as equivalent methods by the EPA.
Additionally, the Company's carbon monoxide have been approved as equivalent
methods by the EPA. The Company is currently testing a particulate analyzer
(beta ray attenuation) for approval as an equivalent method by the EPA. The
Company has never had, or been threatened with, a recall as the result of
subsequent testing by the EPA of a production model of any of its instruments.

     The Company believes that, as the performance of air monitoring equipment
improves and monitoring technology becomes available in the market, government
regulatory agencies tend to adopt regulations requiring the use of such
technology. The Company has never been required to modify or discontinue any of
its products as a result of improved technology. However, there can be no
assurance that future technological improvements will not mandate changes in, or
cause the obsolescence of, Company products.

Governmental Regulation and Enforcement

     Legislation requiring more precise air pollution monitoring and enforcement
is increasing as the sophistication of the technology improves and as concern
for the environment, particularly the depletion of the ozone layer, becomes more
acute. The Clean Air Act and the Clean Air Act Amendments of 1990 (the "1990
Amendments"), require increased control of industrial air pollution and
represent an increasing threat of shut-down for U.S. industrial concerns which
fail to obtain necessary permits and engage in other conduct violative of the
legislation. Because increased control requires increased management and
monitoring of air pollutants by government and industry, the Company expects,
but cannot assure, an increasing market for its products. Company management
believes that governmental enforcement policy also has a significant effect on
the demand for the Company's products. A relaxation during 1982 in the federal
enforcement of governmental standards resulted in a decrease in demand for the
Company's products. Since then, the worldwide trend toward increasingly
stringent environmental standards for industrial air pollution together with
stricter governmental enforcement of environmental regulations, is expected by
management to cause continued expansion of segments of the analytical
instruments market and a continued increase in demand for the Company's
products. In essence, the Company furnishes a product that the customer does not
want to buy voluntarily. In previous years, price difference was not significant
to the selection process. Since 1994, sizeable discounts have become significant
to the purchasers.

Company Products

     In 1972, the Company developed, and in 1974 initially marketed, the first
ultraviolet ozone monitor, of which eight models are currently marketed by the
Company, including high concentration, manual, remote and
microprocessor-controlled versions. The Company will continue to seek to develop
new versions of its basic model of ozone monitor, but does not expect any change
in the basic principle upon which the instrument operates. Since 1974 the
Company has been generally considered the leader in ozone measurement technology
in the world.

     The Company developed microprocessor-controlled carbon monoxide, sulfur
dioxide and oxides of nitrogen monitors in 1981, 1986 and 1987, respectively.

     Calibration equipment, which is utilized to independently verify the
measurements made by other monitoring equipment, was first manufactured and sold
by the Company in 1976 and known as the "Auditor," was followed by a
manually-operated, portable model which performs similar functions. In 1990,
both of these models were superseded by the Company's Model 5008
state-of-the-art, programmable calibration equipment.

     The Company completed development, in 1991, of a Model 7001 beta-gauge to
measure sub- micronic particulates, a Model 8001 data-logger to gather and
transmit measured air pollutant information.

     In February 1994, the Company acquired the technology and inventory of the
Byron Hydrocarbon Analyzer line which resulted in a completion of the ability to
offer a System 1000. This analyzer is a micro- processor controlled, gas
chromatograph type methane, non-methane analyzer designated as Model 302.

     All instruments plus proprietary reporting and predictive software (See
"Research and Development") comprise a System 1000 which can serve as a
stand-alone satellite in a regional monitoring network.

     The Company offers a two-year warranty on all of its instruments, with the
exception of certain components, such as lamps, which have short lives. With
respect to such components, the Company passes on to the customer the warranty
(usually one year) which it receives from the manufacturer. The Company's
warranty provides for repair or replacement of defective products. During each
of the last five fiscal years, the Company has been required to honor its
warranty with respect to less than 0.3% of total instruments sales during each
such year.

Marketing and Sales; Backlog Instruments

     The marketing and sales activities of the Company include advertising by
mail and in trade journals (primarily Pollution Equipment News and Air Pollution
Control Association Journal) and attendance and exhibition at worldwide air
pollution conferences. The Company attends the annual conference of the Air
Pollution Control Association as well as worldwide conferences. The Company's
core business instruments have been sold to customers world-wide, including
industrial manufacturers; federal, state, city, local and foreign governmental
agencies; major industrial companies; and educational and research institutions
in over 30 countries. Sales made in the United States are handled directly by
the Company's sales staff. Nearly all of the Company's foreign sales are made to
distributors who, in turn, resell to the end users. The Company sells to these
distributors at a discount from the listed price. Management believes that,
normally, the loss of a distributor who may account for a large percentage of
sales would have little impact on net revenues as the end users of the Company's
products could be transferred to new distributors.

     An exception in foreign sales is China. Here the Company's distributor
serves a dual role with primary emphasis on a role as a representative, when the
Company sells direct to the government. The recent China contract (See "Foreign
Sales") is a direct sale. Further, it is expected that a loss of this
distributor or representative would have a materially adverse impact on the
Company's revenues.

     Historically, foreign sales represented approximately 50 percent of the
Dasibi Environmental subsidiary - the core business. Currently foreign sales
account for approximately 85%. In 1999, one customer, China, accounted for 67%
of the sale of the Company products.

     The Company's core business sales in the export market are evenly
distributed among all of its products. Export sales are billed and paid in
United States dollars only. In 2000, it is expected that one customer, China,
may account for as much as 90% of the sale of the Company products.

     The Company's core business instruments have been sold during the past 10
years to over 500 customers in the U.S. and over 30 foreign countries and have
been made up of a small percentage (3% to 5%) industrial manufacturers of
Fortune 500 size, and the remaining percentage in state, city, local, federal,
foreign governmental agencies, and educational and research institutions. The
technological life of the largest selling instrument of the Company to nearly
all of the referenced customers - the 1003-AH Ozone Monitor, is thirty years and
counting - still ordered currently. Since 1994 a competitive price pressure by

                                        9


<PAGE>



large instrument manufacturers has resulted in continually declining sales with
a corresponding loss in the total number of customers each year. Therefore while
the percentages indicated above are fairly stable, the Company has reorganized
to focus its marketing and sales efforts to a single, but largest market in the
world. The Company now has a "base" core business of customers in the U.S. and
around the world which is relatively small but requires only minimum marketing
effort, and a potentially large China business which can be pursued efficiently.

     Historically, none of the Company's business has been subject to the
re-negotiation of profits, and no government orders have ever been terminated.
The indicated core business backlog at December 31, 1999 was approximately
$400,000 which amount the Company considers immaterial. However, the Company has
a letter of intent from China for approximately 10 to 12 million dollars. The
Company believes that the contract will be signed during April, 2000 and that
the project can be commenced no later than July, 2000. Commencement of the
project before the end of July in the year 2000 is a material condition to the
Company's profitability or loss status for the year 2000.

Foreign Sales

     The following table sets forth certain information regarding the Company's
foreign sales for the last two fiscal years:
                                                              Year Ended

                                                              (In thousands)
 Aggregate sales to unaffiliated foreign customers:

 Europe and The United Kingdom                            $  358         $ 987

 Asia and Pacific Rim                                     $5,200         $ 934

 Latin America & Other                                    $  173         $ 397



     During the fiscal year ended December 31, 1998 no one customer accounted
for more than 10% of net sales. During fiscal 1999 China accounted for more than
65% of net sales.

     Historically, backlog has not been significant to the Company's operations
because orders usually require delivery in 45 to 60 days. As of December 31,
1999, the Company had approximately $400,000 in "firm" orders which required
delivery in 90 days or less, a backlog which the Company does not consider
significant.

Manufacturing and Purchasing

     The Company manufactures many components and subsystems for use in its
products, including critical optical components and analog and digital

                                       10


<PAGE>


circuitry. Other components, including packaging materials, integrated circuits,
microprocessors and minicomputers, are purchased from unaffiliated third
parties. Most of the raw materials and supplies purchased by the Company are
either available from a number of different suppliers or alternative sources
could be developed without a materially adverse effect on the Company's
business. However, the availability and quality of certain key instrument
components, such as printed circuit board designs and lamps, are controlled by a
limited number of vendors. A vendor's inability to supply these components to
the Company in a timely fashion, or to the Company's satisfaction, can affect
the Company's ability to deliver its instruments on time.

Research and Development

     Historically, the Company has been actively engaged in research and
development in order to produce new products. However, the competitive price
pressures experienced by the Company since early 1994 have sharply limited the
new product development to areas of software as opposed to hardware. Developed
over the past three years, DECS (Dasibi Environmental Central Software) is a
Windows-based, network control and reporting program for multi systems of
pollutant analyzers and ancillaries. Similar programs exist but management
believes none are under single manufacturer design and responsibility. Within
the same constraints, the Company is developing predictive pollutant modeling
programs.

     Because of competive price pressure budget restraints, the Company has been
limiting Flue Gas Purification System development work.

Employees

     As of April 6, 2000, the Company had 45 full-time employees, of whom 5 were
engaged in administration, 7 in engineering, 31 in manufacturing and 2 in sales
and marketing. None of the Company's employees are represented by a labor union.
The Company has never had a strike or lockout and considers its employee
relations to be good.

Competition - Instruments

     The Company is the smallest competitor in the ambient air pollution
instrumentation market. Therefore, it is subject to the effects of
better-financed competitors and their research and development efforts, and
price discounting. The Company competes on the basis of technical advances in
its products and its reputation among customers as a quality provider of
products and services. To a lesser extent, the Company competes on the basis of
price.

     Although the Company is not aware of any other company that competes with
it in all of its product lines and software capabilities, all of its competitors
have resources substantially greater than those of the Company. There are also
smaller companies that specialize in a limited number of the types of products
manufactured by the Company. The Company's primary competitors in the domestic
market are Thermo Instrument Systems, Inc. ("Thermo Instrument Systems") and
Monitor Labs, Inc. ("Monitor Labs"). In the foreign market, the Company's
primary competitors are Thermo Instrument Systems, Monitor Labs, Environnement
S.A of France ("Environnement") and Horiba Instruments ("Horiba Instruments.")

Intellectual Property

     Although the Company obtained patents for its ozone monitor and various
techniques in instrument design, it has generally been the Company's policy to
proceed without patent protection since it is management's belief that the
disclosure requirements of the federal patent laws provide competitors with easy
access to the secrets of rapidly changing technology. The instrument patents
obtained by the Company, all of which have expired, are not deemed by management
to be significant to the Company's business operations or potential success. The
Company has no federal or state registered trademarks and no franchises or
concessions. The Company has common law rights to the trademark "Dasibi."

     Albert E. Gosselin, Jr., the Company's co-founder, has, for the past
several years, devoted personal research time to developing an innovative, cost
conscious system for purifying exhaust gases. His efforts resulted in the filing
of a patent application for such system on behalf of the Company in April 1994,
subsequently granted in September 1996, and a second grant in March, 1999, both
assigned to the Company for $1.00.

Item 2. Description of Properties

     In July 1994, the Company moved its administrative, instrument
manufacturing and employee facilities to 39,070 square feet, increased to 45,000
square feet in 1997, at 506 Paula Avenue, Glendale, California. The Company
leases the space from an unaffiliated third party for a term of ten years
commencing as of July 1, 1994, at a base rent of $24,223 per month plus
operating costs and taxes, with a provision for increases in the base rent
related to increases in the Consumer Price Index to the present rent of $31,000
per month. The Company utilizes most of its existing office and manufacturing
space and believes that such space is more than adequate for its needs for the
foreseeable future.

Item 3. Legal Proceedings

foreseeable future.

     A one for four reverse split of the Company's Common Stock was approved by
shareholders during 1998 and all values pertaining to the Company's stock have
been adjusted in this report. As of April 6, 2000, there are 4,235,085 shares of
Common Stock outstanding, 1,093,206 warrants and 784,625 options.

Item 6. Management's Discussion and Analysis or Plan of Operation

1999
- ----

     The Company has been in a transitional operation phase since early 1998.
Recent years have indicated that the Company's "base" core business is in the
range of $2.6 million in revenues. During 1998, the Company demonstrated a
self-sustaining break-even operation at this revenue with a total staff of 20
personnel. To handle the large China orders which are, at present,
unpredictable, a total staff of 45 minimum is indicated. Therefore, until a
"steady-state" flow of revenue from China is reached a monthly loss situation is
expected for portions of each year. "Ramping-up" is not feasible in the
employment market for technical personnel as has existed during the past
eighteen months in the United States. Management believes that acceptance of a
staggered profit-loss monthly operation is necessary to properly access the very
large China market. In 1999, management estimates seven of the twelve months
could be considered as accepted high fixed expense months in this transition
effort. In 2000, each month to date has also been an accepted high fixed expense
month with no China activity.

                                       14


<PAGE>


     Financing when needed, even in the form of State or Federal guaranteed
loans involves lending institutions' extremely high management fees.
Non-guaranteed loans demand extremely high interest rates. Finally, equity
placements require significant discounts and incentives.

     The combination of accepted high fixed expense months described above and
the aforementioned high expenses associated with access to capital tend to lower
the possible operational performance of fiscal 1999 and any subsequent year that
may have minimum China market activity. Pro-formas for specific China
performance have been and will continue to be used as a guide for maintaining
acceptable gross profit margins.

     Net revenues in 1999 were $7,314,975 compared to $2,807,511 in 1998, a 161%
increase. The increase was entirely due to China business. The revenues for the
"base" core business were essentially the same as the year before.

     Gross margin was 30% of consolidated net revenues in 1999 compared to 35%
of the consolidated revenues of 1998. The gross margin during the five months of
full China operation has been estimated at approximately 44%, from pro-forma
analysis.

     Selling, general and administrative expenses increased from a consolidated
$1,583,679 in 1998 to $2,952,652 in 1999 due to increased staffing, related
expense and commissions. A higher level of promotional charges during no China
operation contributed an increase of approximately $246,000 in 1999, over 1998.
The remaining increase is primarily due to an increase in commission and freight
which is directly related to the increase in revenues.

     Research and development expense increased from $20,175 in 1998 to $70,830
in 1999 due to in-house technological advances in the Company's system work.

     Interest expense increased from $27,961 in 1998 to $336,675 in 1999,
primarily due to the Company's inability to obtain bankable financing for higher
levels of working capital required.

     Management fees from lending institutions (non-bankable penalties) were
approximately $400,000 and is not comparable to 1998. Amortization of loan fees
was $359,106. The combination of these factors amounted to approximately
$760,000.

     Management believes that the Phase II contract in excess of $12 million
will be awarded to the Company in April, 2000 and it is believed the project can
be commenced within 60 days of the contract signing. Based on 1999 pro-forma
analysis,over six months of China operation in 2000 should result in a
profitable year-end. Further, the balance of the project extending into 2001 and
currently indicated non- related China Phase II awards along with a strong
indication of joint venture manufacture in China commencing in June, 2001 given
extremely high probability of year round gross profit margins in the range of
44% which historically has proven profitable to the Company.


                                       15


<PAGE>


     The Company, at December 31, 1999, has an approximate net operating loss
carry-forward of $6 million.

     Based on the pro-forma 1999 results of the China operations and the above
forecast, management believes that a deferred tax credit applied to its
operating situation wherein as planned expenses for increased revenue and gross
profit margin have been accepted and therefore a deferred tax credit is
appropriate.

     The approximate $6 million net operating loss carry forward resulted in a
$2,659,000 tax credit and was applied as a 1999 income tax benefit as an asset
and an increase to operating income.

     Primarily as a result of the use of the loss carry forward, net income was
$1,125,637 in 1999 compared to a net loss of $1,588,746 in 1998.

     Proforma estimates on the Company's subsidiary operation indicate an
estimated $800,000 profit from core activities on revenues of $7,314,975
exclusive of financing limitations, excluding fixed expense of the non-China
operation for 7 months of 1999, and including accrued expenses for year 2000
related China operations.

1998 and Prior
- --------------

     The Company's operating profit for fiscal 1994, 1995, 1996, 1997, and 1998
decreased significantly as compared to fiscal 1993. These declines were
principally because of significant competitive price pressure for the Company's
air pollution monitoring instruments, thus forcing the Company to lower its
domestic and foreign bids, reducing the number of the Company's bids awarded and
reducing the profit margin on the bids awarded to the Company. In the middle of
1996 two companies were acquired in an attempt to diversify the Company's
technology and to increase profit margins. The Company's revenue overall
increased in 1996 and 1997 due to these acquisitions, however, the profit margin
did not increase and the additional overhead continued the downward trend for
the Company. Beginning in the third quarter of fiscal 1994, the Company
implemented certain cost reduction measures in its operating expenses, suspended
major new product development efforts and scaled back its efforts to improve or
modify existing technologies in response to the competitive price pressures.
Throughout 1995 and 1996 the Company shipped record numbers of instrumentation
units, but continued competitive pricing pressure resulted in lowered gross
margins. In July 1996 the above acquisitions were completed. The program to
diversify was deemed unsuccessful and a reorganization was begun in early 1998
consisting of the disposition of acquired subsidiary assets and a reduction of
personnel. Management determined that the focus of its core business should be
redirected to an attempt to achieve designated vendor status in the People's
Republic of China. In June 1998 the Company was awarded the largest contract in
its history, in excess of $5 million dollars, in a designated vendor's status.
Due to banking factors outside of the control of the contractual parties no
China contract revenues were obtained during 1998.

Liquidity and Capital Resources

     The Company has historically financed operations through bank borrowings
and the issuance of common stock in both public and private offerings. Since the
Company has not been considered "bankable" the cost of money obtained from
financial institutions has been relatively expensive.

                                       16


<PAGE>

     Since January 1999, the Company has raised $1,210,654 in private placements
which has resulted in the issuance of 1,277,538 shares of Common Stock and
options and warrants for 867,538 shares.

     Working capital at December 31, 1999 was $1,346,211. Management believes
that the anticipated cash flows from operations will be sufficient to meet the
Company's cash needs for the next twelve months. As of April 6, 2000, the
Company had no material commitments for capital expenditures.

     During 1999 and to date the Company entered into several loans with varying
terms:

     A.   $300,000 in three one year loans maturing June 1, 2000 with interest
          rate at 12% with unaffiliated individuals.

     B.   One $500,000 Convertible Bond with interest at 18% due March 2000 and
          currently replaced with a $500,000 Convertible Loan with interest at a
          12% interest rate due December, 2000. Convertible at $2.25 or 80% of
          market price, whichever is lower - no conversion applied for to this
          date.

     C.   One $300,000 Convertible Bond with interest at 12% due June 1, 2000
          convertible at $2.25 or 80% of market, whichever is lower. 119,108
          shares have been converted to date at levels of $1.20 to $2.25.
          Balance of loan due is $75,000.

     D.   One $500,000 Convertible Bond with interest at 12% due March 2001.
          Convertible at $2.00 or 80% of market price, whichever is lower - no
          conversion applied for to this date.

     Management believes that all of the above debt instruments can be satisfied
or restructured if necessary.

     Cash increased from $63,952 at the end of 1998 to $214,206 at the end of
1999.

Seasonality

     Management does not believe that the Company's business is seasonal.

shares of Series A Preferred Stock to each of Messrs. Albert E.Gosselin and Gary
L. Dudley, executive officers and/or directors of the Company, respectively, in

consideration of 450,000 shares of the Company's Common Stock. In early 1999,

                          INDEPENDENT AUDITORS' REPORT


Board of Directors
Pollution Research and Control Corp.
Glendale, California


We have audited the accompanying consolidated balance sheet of Pollution
Research and Control Corp. and Subsidiaries as of December 31, 1999, and the
related consolidated statements of operations and comprehensive income (loss),
stockholders' equity and cash flows for the years ended December 31, 1999 and
1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Pollution Research
and Control Corp. and Subsidiaries as of December 31, 1999, and the consolidated
results of their operations and their cash flows for the years ended December
31, 1999 and 1998 in conformity with generally accepted accounting principles.

              POLLUTION RESEARCH AND CONTROL CORP. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 FOR THE YEARS ENDED DECEMBER 31, 1999 AND 1998


NOTE 1 - BUSINESS ACTIVITY

Pollution Research and Control Corp., a California corporation, primarily
designs, manufactures and markets air pollution monitoring instruments, through
its wholly-owned subsidiary Dasibi Environmental Corporation ("Dasibi").
Pollution Research and Control Corp. had designed and manufactured electrical
control panels and medical instrumentation through its wholly-owned subsidiaries
Nutek, Inc. ("Nutek"), and Logan Medical Devices, Inc. ("LMD") and LMD's wholly
owned subsidiary, Logan Research Limited ("LRL"), respectively. The operations
of Nutek and LRL were discontinued in 1998 (Note 6).

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Consolidation
- -------------
The consolidated financial statements include the accounts of Pollution Research
and Control Corp. and its wholly-owned subsidiaries (the "Company"). All
significant intercompany balances and transactions have been eliminated in
consolidation.

Revenue Recognition
- -------------------
Revenue is recognized upon shipment of products.

Inventories
- -----------
Inventories are stated at the lower of cost (first-in first-out) basis or
market.

Property, Equipment and Leasehold Improvements and Depreciation
- ---------------------------------------------------------------

Property, equipment and leasehold improvements are stated at cost less
accumulated depreciation and amortization. Depreciation is provided for on the
straight-line method over the estimated useful lives of the assets, generally
five to ten years. Amortization of leasehold improvements is over the shorter of
the life of the lease or five years. Total depreciation expense was $23,150 and
$28,591 for the years ended December 31, 1999 and 1998, respectively.

Stock-Based Compensation
- ------------------------
The Company accounts for stock based compensation in accordance with Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" ("SFAS 123"). This standard requires the Company to adopt the
"fair value" method with respect to stock-based compensation of consultants and
other non-employees. The Company did not change its method of accounting with
respect to employee stock options; the Company continues to account for these
under the "intrinsic value" method, and to furnish the proforma disclosures
required by SFAS 123. See Notes 10 and 11 for additional information with
respect to stock-based compensation.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                 FOR THE YEARS ENDED DECEMBER 31, 1999 AND 1998


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Earnings per Share
- ------------------
In 1997, the Financial Accounting Standards Board (FASB) issued Statement No.
128, "Earnings Per Share". Statement 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented, to conform to Statement 128 requirements.

Cash Equivalents
- ----------------
For purposes of reporting cash flows, the Company considers all funds with
original maturities of three months or less to be cash equivalents.

Fair Value of Financial Instruments
- -----------------------------------
The carrying amounts of cash, accounts receivable, accounts payable and accrued
expenses approximate fair value because of the short maturity of these items.

Impairment Of Long-Lived Assets
- -------------------------------
The Company evaluates its long-lived assets by measuring the carrying amounts of
assets against the estimated undiscounted future cash flows associated with
them. At the time such evaluations indicate the future undiscounted cash flows
of certain long-lived assets are not sufficient to cover the carrying value of
such assets, the assets are adjusted to their fair values.

Research and Development Costs
- ------------------------------
Research and development costs are charged to operations as incurred. Research
and development expense was $70,830 and $20,175 for the years ended December 31,
1999 and 1998, respectively.

Income Taxes
- ------------
Deferred income taxes are recorded to reflect the tax consequences in future
years of temporary differences between the tax basis of the assets and
liabilities and their financial statement amounts at the end of each reporting
period. Valuation allowances are established when necessary to reduce deferred
tax assets to the amount expected to be realized. Income tax expense is the tax
payable for the current period and the change during the period in deferred tax
assets and liabilities. The deferred tax assets and liabilities have been netted
to reflect the tax impact of temporary differences. At December 31, 1999 no
valuation allowance has been established for the deferred tax asset as
management believes that it is more likely than not that a tax benefit will be
realized.

                 FOR THE YEARS ENDED DECEMBER 31, 1999 AND 1998


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Use of Estimates in the Preparation of Financial Statements
- -----------------------------------------------------------
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

Reclassification
- ----------------
Certain  amounts  reported in the Company's  financial  statements  for the year
ended December 31, 1998 have been reclassified to conform to the current year
presentation.

Year 2000 Issues
- ----------------
Many computer systems and other equipment with embedded chips or microprocessors
may not be able to appropriately interpret dates after December 31, 1999 because
such systems use only two digits to indicate a year in the date field rather
than four digits. If not corrected, many computers and computer applications
could fail or create miscalulations, causing disruptions to the Company's
operations. In addition, the failure of customer and supplier computer systems
could result in interruption of sales and deliveries of key supplies or
utilities. Because of the complexity of the issues and the number of parties
involved, the Company cannot reasonably predict with certainty the nature or
likelihood of such impacts.

While the Company believes that its own internal assessment and planning efforts
with respect to external service providers, suppliers, customers and financial
institutions are and will be adequate to address its Year 2000 concerns, there
can be no assurance that these efforts will be successful or will not have a
material adverse effect on the Company's operations. Costs in connection with
compliance were not significant.

To date, the Company has not experienced any interruptions with respect to the
Year 2000 issue, but cannot reasonably predict with certainty that they will not
experience any interruptions.

Inventories at December 31, 1999 consisted of the following:

                                                            =============

NOTE 5 - DEFERRED RENT

Upon execution of a 10 year lease for its present facility in Glendale,
California commencing July 1, 1994, the Company was granted 6 months "free"
rent. As required by generally accepted accounting principles, rent expense is
being recognized by amortizing the total minimum rentals payable under the lease
over the terms of the lease on a straight-line basis. The deferred rent shown on
the balance sheet as of December 31, 1999 represents the excess of the total
amount charged to rent expense over the amounts actually due and payable under
the lease as of such date, of which $23,012 has been classified as current and
$43,602 as long term, respectively.

NOTE 6 - DISCONTINUED OPERATIONS

Nutek -
In April 1998, Nutek filed for protection under the Federal  Bankruptcy Code. In
June  1998,  the  Bankruptcy  Court  permitted  the  sale of  Nutek's  mortgaged
property, to satisfy the working capital facility and term loan obligations to
the major secured lender. The results of operations for Nutek for the respective
periods  are  reported  as  a  component  of  discontinued   operations  in  the
consolidated  statements of operations.  Additionally,  the loss incurred on the
disposition/abandonment  of assets and liabilities is also presented  separately
as a component of discontinued operations.

Logan Research, Ltd. -
In February 1998, the Company disposed of LRL, through a return of 100% of LRL's
stock to its original owner in exchange for release from a $300,000 note payable
and $47,250 of related accrued interest. Unsecured advances from an officer of
LRL were not repaid. The results of operations of LRL for the respective periods
are reported as a component of discontinued operations in the consolidated
statements of operations. Additionally, the gain (loss) incurred on the disposal
of LRL is also presented separately as a component of discontinued operations.

NOTE 7 - ACCRUED SETTLEMENT

Under a settlement reached in 1998 and finalized in June 1999, the Company
entered into a compromise settlement agreement with the previous major secured
lender of Nutek to repay $468,000 through the issuance of 100,000 shares of the
Company's common stock (valued at $1.75 per share on the date of issuance) and
payment on February 1, 2000 of the remaining balance due, including interest
accruing from the settlement date at 12% per annum. The shares were placed in
escrow to be sold to reduce the balance owed under the settlement agreement. In
addition, the Company issued warrants to purchase 20,000 shares of the Company's
common stock at $.75 per share as an inducement to enter into the settlement
agreement.

The Company did not make its required payment in February 2000 and in March 2000
entered into amendment to the compromise settlement agreement and agreed to
place $200,000 in escrow for the remaining balance owed.

NOTE 11 - STOCK-BASED COMPENSATION

The Company accounts for stock based compensation in accordance with Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation". The standard requires the Company to adopt the "fair value"
method with respect to stock-based compensation of consultants and other
non-employees, which resulted in charges to operations of $309,106 and $54,977
during the years ended December 31, 1999 and 1998, respectively. Additionally,
$24,790 was capitalized as offering costs in connection with the private
placement in 1998. During 1999, the Company capitalized $65,730 in loan fees.

The Company did not adopt the fair value method with respect to employee stock
options; the Company continues to account for these under the "intrinsic value"
method. Had the Company adopted the fair value method with respect to options
issued to employees as well, an additional $35,617 would have been charged to
income in 1998; proforma net loss would have been $1,607,000 and net loss per
share would have been $.70 on both a basic and diluted basis.

NOTE 11 - STOCK-BASED COMPENSATION (Continued)

In 1998 the Board approved a reduction in the exercise price for options granted
to certain employees, consultants, and other non-employees. Because of this, it
was necessary to calculate the difference between the fair value of the modified
option and the value of the old option immediately before the terms were
modified.

The Company did not adopt the fair value method with respect to employee stock
options; the Company continues to account for these under the "intrinsic value"
method. Had the Company adopted the fair value method with respect to options
issued to employees as well, an additional $48,000 would have been charged to
income in 1999; proforma net income would have been $1,077,687 and net income
per share would have been $.31 on the basic basis and $.28 on the diluted basis.

          SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
          SECURITIES LAWS IS NOT REQUIRED.

          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants.

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and
agrees that all shares of Warrant Stock which may be issued upon the exercise of
this Warrant or otherwise  hereunder  will, upon issuance,  be duly  authorized,
validly issued, fully paid and non-assessable and free from all taxes, liens and
charges  created by or through  the Issuer.  The Issuer  further  covenants  and
agrees that during the period  within which this Warrant may be  exercised,  the
Issuer will at all times have  authorized  and  reserved  for the purpose of the
issue upon  exercise  of this  Warrant a  sufficient  number of shares of Common
Stock to provide for the exercise of this Warrant.



<PAGE>

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

          (i) not permit the par value, if any, of its Common Stock to exceed
     the then effective Warrant Price,

          (ii) no amend or modify an provision of the Certificate of
     Incorporation or by-laws of the Issuer in any manner that would adversely
     affect in any way the powers, preferences or relative participating,
     optional or other special rights of the Common Stock or which would
     adversely affect the rights of the Holders of the Warrants,

          (iii) take all such action as may be reasonably necessary in order
     that the Issuer may validly and legally issue fully paid and nonassessable
     shares of Common Stock, free and clear of any liens, claims, encumbrances
     and restrictions (other than as provided herein) upon the exercise of this
     Warrant, and

                           (iv)  use  its  best   efforts  to  obtain  all  such
                  authorizations,   exemptions   or  consents  from  any  public
                  regulatory  body  having   jurisdiction   thereof  as  may  be
          reasonably necessary to enable the Issuer to perform its
                  obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or



<PAGE>


destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

     (i) In case the Issuer after the Original Issue Date shall do any of the
following (each, a "Triggering Event"):

               (a) consolidate with or merge into any other Person and the
     Issuer shall not be the continuing or surviving corporation of such
     consolidation or merger, or

               (b) permit any other Person to consolidate with or merge into the
     Issuer and the Issuer shall be the continuing or surviving Person but, in
     connection with such consolidation or merger, any Capital Stock of the
     Issuer shall be changed into or exchanged for Securities of any other
     Person or cash or any other property, or

               (c) transfer all or substantially all of its properties or assets
     to any other
                  Person, or

               (d) effect a capital reorganization or reclassification of its
     Capital Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such


<PAGE>


Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the
adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

     (ii) Notwithstanding anything contained in this Warrant to the contrary,
the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than the Issuer) which may be required
to deliver any Securities, cash or property upon the exercise of this Warrant as
provided herein shall assume, by written instrument delivered to, and reasonably
satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer
under this Warrant (and if the Issuer shall survive the consummation of such
Triggering Event, such assumption shall be in addition to, and shall not release
the Issuer from, and continuing obligations of the Issuer under this Warrant)
and (B) the obligation to deliver to such Holder such shares of Securities, cash
or property as, in accordance with the foregoing provisions of this subsection
(a), such Holder shall be entitled to receive, and such Person shall have
similarly delivered to such Holder an opinion of counsel for such Person, which
counsel shall be reasonably satisfactory to such holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of the subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to delivery upon any exercise of this Warrant or the exercise of any
rights pursuant hereto.

     (iii) If with respect to any Triggering Event, the Holder of this Warrant
has exercised its right as provided in clause (y) of subparagraph (i) of this
subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees that
as a condition to the consummation of any such Triggering Event the Issuer shall
secure such right of Holder to sell this Warrant to the Person continuing after
or surviving such Triggering Event and the Issuer shall not effect any such
Triggering Event unless upon or prior to the consummation thereof the amounts of
cash, property and/or Securities required under such clause (y) are delivered to
the Holder of this Warrant. The obligation of the Issuer to secure such right of
the Holder to sell this Warrant shall be subject to such Holder's cooperation
with the Issuer, including, without limitation, the giving of customary
representations and warranties to the purchaser in connection with any such
sale. Prior notice of any Triggering Event shall be given to the Holder of this
Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of



<PAGE>


so subdividing, as at the applicable record date, whichever is earlier) to
reflect the increase in the total number of shares of Common Stock outstanding
as a result of such subdivision, or (ii) in the case of a combination of shares,
the Warrant Price shall be proportionately increased (as at the effective date
of such combination or, if the Issuer shall take a record of Holders of its
Common Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or


<PAGE>

acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately
after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.

<PAGE>


          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the



<PAGE>


foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

     Issuer, after receipt of the determination by such Independent Appraiser,
     shall have the right to select an additional Independent Appraiser, in
     which case, the fair market value shall be equal to the average of the
     determinations by each such Independent Appraiser; and provided, further

     appropriately adjusted for any stock dividends, stock splits or other
     similar transactions during such period. The Issuer shall pay all costs and

     value by an Independent Appraiser shall be based upon the fair market value
     of the Issuer determined on a going concern basis as between a willing
     buyer and a willing seller and taking into account all relevant factors
     determinative of value, and shall be final and binding on all parties. In

     Stock imposed by agreement or by federal or state securities laws, or to

such terms may be specifically enforced by a decree for the specific performance
of any agreement contained herein or by an injunction against a violation of any

provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     that this Warrant or the shares of Warrant Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account and not as a
     nominee for any other party, and for investment, and that the Holder will
     not offer, sell or otherwise dispose of this Warrant or any shares of
     Warrant Stock to be issued upon exercise hereof except pursuant to an
     effective registration statement, or an exemption from registration, under
     the Securities Act and any applicable state securities laws.

          (ii) Except as provided in paragraph (iii) below, this Warrant and all
     certificates representing share of Warrant Stock issued upon exercise
     hereof shall be stamped or imprinted with a legend in substantially the
     following form:

               THIS WARRANT AND THE SHARE OF COMMON STOCK ISSUABLE UPON EXERCISE
               HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,

               REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE
               SECURITIES LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF
               ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
               SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
               SECURITIES LAWS IS NOT REQUIRED.

          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through the Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at
all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any



<PAGE>


federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

          (i) not permit the par value, if any, of its Common Stock to exceed
     the then effective Warrant Price,

          (ii) no amend or modify an provision of the Certificate of
     Incorporation or by-laws of the Issuer in any manner that would adversely
     affect in any way the powers, preferences or relative participating,
     optional or other special rights of the Common Stock or which would
     adversely affect the rights of the Holders of the Warrants,

          (iii) take all such action as may be reasonably necessary in order
     that the Issuer may validly and legally issue fully paid and nonassessable
     shares of Common Stock, free and clear of any liens, claims, encumbrances
     and restrictions (other than as provided herein) upon the exercise of this
     Warrant, and

          (iv) use its best efforts to obtain all such authorizations,
     exemptions or consents from any public regulatory body having jurisdiction
     thereof as may be reasonably necessary to enable the Issuer to perform its
     obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such




<PAGE>


Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

     (i) In case the Issuer after the Original Issue Date shall do any of the
following (each, a "Triggering Event"):

          (a) consolidate with or merge into any other Person and the Issuer
     shall not be the continuing or surviving corporation of such consolidation
     or merger, or

          (b) permit any other Person to consolidate with or merge into the
     Issuer and the Issuer shall be the continuing or surviving Person but, in
     connection with such consolidation or merger, any Capital Stock of the
     Issuer shall be changed into or exchanged for Securities of any other
     Person or cash or any other property, or

          (c) transfer all or substantially all of its properties or assets to
     any other Person, or

          (d) effect a capital reorganization or reclassification of its Capital
     Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such
Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the



<PAGE>


adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

     (ii) Notwithstanding anything contained in this Warrant to the contrary,
the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than the Issuer) which may be required
to deliver any Securities, cash or property upon the exercise of this Warrant as
provided herein shall assume, by written instrument delivered to, and reasonably
satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer
under this Warrant (and if the Issuer shall survive the consummation of such
Triggering Event, such assumption shall be in addition to, and shall not release
the Issuer from, and continuing obligations of the Issuer under this Warrant)
and (B) the obligation to deliver to such Holder such shares of Securities, cash
or property as, in accordance with the foregoing provisions of this subsection
(a), such Holder shall be entitled to receive, and such Person shall have
similarly delivered to such Holder an opinion of counsel for such Person, which
counsel shall be reasonably satisfactory to such holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of the subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to delivery upon any exercise of this Warrant or the exercise of any
rights pursuant hereto.

     (iii) If with respect to any Triggering Event, the Holder of this Warrant
has exercised its right as provided in clause (y) of subparagraph (i) of this
subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees that
as a condition to the consummation of any such Triggering Event the Issuer shall
secure such right of Holder to sell this Warrant to the Person continuing after
or surviving such Triggering Event and the Issuer shall not effect any such
Triggering Event unless upon or prior to the consummation thereof the amounts of
cash, property and/or Securities required under such clause (y) are delivered to
the Holder of this Warrant. The obligation of the Issuer to secure such right of
the Holder to sell this Warrant shall be subject to such Holder's cooperation
with the Issuer, including, without limitation, the giving of customary
representations and warranties to the purchaser in connection with any such
sale. Prior notice of any Triggering Event shall be given to the Holder of this
Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a combination of shares, the




<PAGE>


Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of Holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately


<PAGE>


after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.




<PAGE>


          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>


     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO

(together with its successors and assigns, the "Issuer"), hereby certifies that

purchase, during the period specified in this Warrant, up to 22,500 shares
(subject to adjustment as hereinafter provided) of the duly authorized, validly
issued, fully paid and non- assessable Common Stock of the Issuer, at an
exercise price per share equal to the Warrant Price then in effect, subject,
however, to the provisions and upon the terms and conditions hereinafter set

whole or in part, by the surrender of this Warrant (with the exercise form
attached hereto duly executed) at the principal office of the Issuer, and by the
payment to the Issuer of an amount of consideration therefor equal to the

Warrant shall not then have been exercised (less any amount thereof which shall
have been canceled in payment or partial payment of the Warrant Price as

Holder executing an assignment in the form attached hereto) and upon payment of
any necessary transfer tax or other governmental charge imposed upon such
transfer. This Warrant is exchangeable at the principal office of the Issuer for
Warrants for the purchase of the same aggregate number of shares of Warrant
Stock, each new Warrant to represent the right to purchase such number of shares
of Warrant Stock as the Holder hereof shall designate at the time of such
exchange. All Warrants issued on transfers or exchanges shall be dated the
Original Issue Date and shall be identical with this Warrant except as to the
number of shares of Warrant Stock issuable pursuant hereto.

     (e) Compliance with Securities Laws.

          (i) The Holder of this Warrant, by acceptance hereof, acknowledges
     that this Warrant or the shares of Warrant Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account and not as a
     nominee for any other party, and for investment, and that the Holder will
     not offer, sell or otherwise dispose of this Warrant or any shares of
     Warrant Stock to be issued upon exercise hereof except pursuant to an
     effective registration statement, or an exemption from registration, under
     the Securities Act and any applicable state securities laws.

          (ii) Except as provided in paragraph (iii) below, this Warrant and all
     certificates representing share of Warrant Stock issued upon exercise
     hereof shall be stamped or imprinted with a legend in substantially the
     following form:

          THIS WARRANT AND THE SHARE OF COMMON STOCK ISSUABLE UPON
          EXERCISE HEREOF HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),
          OR ANY STATE SECURITIES LAWS AND MAY NOT BE SOLD,
          TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER
          THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES
          LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF ITS
          COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
          SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
          SECURITIES LAWS IS NOT REQUIRED.

<PAGE>


          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants.

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through the Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at
all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any  governmental  authority  under



<PAGE>


any federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

          (i) not permit the par value, if any, of its Common Stock to exceed
     the then effective Warrant Price,

          (ii) no amend or modify an provision of the Certificate of
     Incorporation or by-laws of the Issuer in any manner that would adversely
     affect in any way the powers, preferences or relative participating,
     optional or other special rights of the Common Stock or which would
     adversely affect the rights of the Holders of the Warrants,

          (iii) take all such action as may be reasonably necessary in order
     that the Issuer may validly and legally issue fully paid and nonassessable
     shares of Common Stock, free and clear of any liens, claims, encumbrances
     and restrictions (other than as provided herein) upon the exercise of this
     Warrant, and

          (iv) use its best efforts to obtain all such authorizations,
     exemptions or consents from any public regulatory body having jurisdiction
     thereof as may be reasonably necessary to enable the Issuer to perform its
     obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such


<PAGE>


Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

     (i) In case the Issuer after the Original Issue Date shall do any of the
following (each, a
"Triggering Event"):

          (a) consolidate with or merge into any other Person and the Issuer
     shall not be the continuing or surviving corporation of such consolidation
     or merger, or

          (b) permit any other Person to consolidate with or merge into the
     Issuer and the Issuer shall be the continuing or surviving Person but, in
     connection with such consolidation or merger, any Capital Stock of the
     Issuer shall be changed into or exchanged for Securities of any other
     Person or cash or any other property, or

          (c) transfer all or substantially all of its properties or assets to
     any other Person, or

          (d) effect a capital reorganization or reclassification of its Capital
     Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such
Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the



<PAGE>


adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

          (ii) Notwithstanding anything contained in this Warrant to the
     contrary, the Issuer will not effect any Triggering Event unless, prior to
     the consummation thereof, each Person (other than the Issuer) which may be
     required to deliver any Securities, cash or property upon the exercise of
     this Warrant as provided herein shall assume, by written instrument
     delivered to, and reasonably satisfactory to, the Holder of this Warrant,
     (A) the obligations of the Issuer under this Warrant (and if the Issuer
     shall survive the consummation of such Triggering Event, such assumption
     shall be in addition to, and shall not release the Issuer from, and
     continuing obligations of the Issuer under this Warrant) and (B) the
     obligation to deliver to such Holder such shares of Securities, cash or
     property as, in accordance with the foregoing provisions of this subsection
     (a), such Holder shall be entitled to receive, and such Person shall have
     similarly delivered to such Holder an opinion of counsel for such Person,
     which counsel shall be reasonably satisfactory to such holder, stating that
     this Warrant shall thereafter continue in full force and effect and the
     terms hereof (including, without limitation, all of the provisions of the
     subsection (a)) shall be applicable to the Securities, cash or property
     which such Person may be required to delivery upon any exercise of this
     Warrant or the exercise of any rights pursuant hereto.

          (iii) If with respect to any Triggering Event, the Holder of this
     Warrant has exercised its right as provided in clause (y) of subparagraph
     (i) of this subsection (a) to sell this Warrant or a portion thereof, the
     Issuer agrees that as a condition to the consummation of any such
     Triggering Event the Issuer shall secure such right of Holder to sell this
     Warrant to the Person continuing after or surviving such Triggering Event
     and the Issuer shall not effect any such Triggering Event unless upon or
     prior to the consummation thereof the amounts of cash, property and/or
     Securities required under such clause (y) are delivered to the Holder of
     this Warrant. The obligation of the Issuer to secure such right of the
     Holder to sell this Warrant shall be subject to such Holder's cooperation
     with the Issuer, including, without limitation, the giving of customary
     representations and warranties to the purchaser in connection with any such
     sale. Prior notice of any Triggering Event shall be given to the Holder of
     this Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a  combination  of shares,



<PAGE>


the Warrant Price shall be proportionately increased (as at the effective date
of such combination or, if the Issuer shall take a record of Holders of its
Common Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall: (i) Stock Dividends. Pay a dividend in, or
make any other distribution to its stockholders (without consideration therefor)
or, shares of Common Stock, the Warrant Price shall be adjusted, as at the date
the Issuer shall take a record of the Holders of the Issuer's Capital Stock for
the purpose of receiving such dividend or other distribution (or if no such
record is taken, as at the date of such payment or other distribution), to that
price determined by multiplying the Warrant Price in effect immediately prior to
such record date (or if no such record is taken, then immediately prior to such
payment of other distribution), by a fraction (1) the numerator of which shall
be the total number of shares of Common Stock outstanding immediately prior to
such dividend or distribution, and (2) the denominator of which shall be the
total number of shares of Common Stock outstanding immediately after such
dividend or distribution (plus in the event that the Issuer paid cash for
fractional shares, the number of additional shares which would have been
outstanding had the Issuer issued fractional shares in connection with said
dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately




<PAGE>


after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

                  (i) Computation of Consideration.  The consideration  received
          by the Issuer shall be deemed to be the following: to the extent that
         any Additional  Shares of Common Stock or any Common Stock  Equivalents
         shall be issued for a cash consideration, the consideration received by
         the Issuer  therefor,  or if such Additional  Shares of Common Stock or
         Common Stock  Equivalents  are offered by the Issuer for  subscription,
         the subscription  price, or, if such Additional  Shares of Common Stock
         or Common Stock  Equivalents  are sold to  underwriters  or dealers for
         public offering  without a subscription  offering,  the public offering
         price,  in any such case  excluding any amounts paid or receivable  for
         accrued  interest or accrued  dividends  and without  deduction  of any
         compensation,  discounts,  commissions, or expenses paid or incurred by
         the  Issuer  for or in  connection  with the  underwriting  thereof  or
         otherwise in  connection  with the issued  thereof;  to the extent that
         such  issuance  shall be for a  consideration  other than  cash,  then,
         except as herein otherwise expressly provided, the fair market value of
         such  consideration  at the time of such issuance as determined in good
         faith by the Board.  The  consideration  for any  Additional  Shares of
         common Stock issuable pursuant to any Common Stock Equivalents shall be
         the consideration  received by the Issuer for issuing such Common Stock
         Equivalents,  plus the additional  consideration  payable to the Issuer
         upon  the  exercise,  conversion  or  exchange  of  such  Common  Stock
         Equivalents.  In case of the  issuance  at any  time of any  Additional
         Shares of Common  Stock or  Common  Stock  Equivalents  in  payment  or
         satisfaction  of any  dividend  upon any class of Capital  Stock of the
         Issuer  other than  Common  Stock,  the Issuer  shall be deemed to have
         received  for such  Additional  Shares of Common  Stock or Common Stock
         Equivalents  a  consideration  equal to the amount of such  dividend so
         paid  or  satisfied.  In any  case in  which  the  consideration  to be
         received or paid shall be other than cash,  the Board shall  notify the
         Holder of this Warrant of its determination of the fair market value of
         such consideration  prior to payment or accepting receipt thereof.  If,
         within thirty days after receipt of said notice,  the Majority  Holders
         shall  notify  the  Board  in  writing  of  their   objection  to  such
         determination,  a  determination  of the  fair  market  value  of  such
         consideration shall be made by an Independent Appraiser selected by the
         Majority  Holders with the approval of the Board (which  approval shall
         not be unreasonable withheld), whose fees and expenses shall be paid by
         the Issuer.

          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>


     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

     12. Remedies. The Issuer stipulates that the remedies at law of the Holder
of this Warrant in the event of any default or threatened default by the Issuer
in the performance of or compliance with any of the terms of this Warrant are
not and will not be adequate and that, to the fullest extent permitted by law,
such terms may be specifically enforced by a decree for the specific performance
of any agreement contained herein or by an injunction against a violation of any
of the terms hereof or otherwise.

     13. Successors and Assigns. This Warrant and the rights evidenced hereby
shall inure to the benefit of and be binding upon the successors and assigns of
the Issuer, the Holder hereof and (to the extent provided herein) the Holders of
Warrant Stock issued pursuant hereto, and shall be enforceable by any such
Holder or Holder of Warrant Stock.

     14. Modification and Severability. If, in any action before any court or
agency legally empowered to enforce any provision contained herein, any
provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     15. Headings. The headings of the Sections of this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

     IN WITNESS WHEREOF, the Issuer has executed this Warrant as of the day and

          (i) The Holder of this Warrant, by acceptance hereof, acknowledges
     that this Warrant or the shares of Warrant Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account and not as a
     nominee for any other party, and for investment, and that the Holder will
     not offer, sell or otherwise dispose of this Warrant or any shares of
     Warrant Stock to be issued upon exercise hereof except pursuant to an
     effective registration statement, or an exemption from registration, under
     the Securities Act and any applicable state securities laws.

          (ii) Except as provided in paragraph (iii) below, this Warrant and all
     certificates representing share of Warrant Stock issued upon exercise
     hereof shall be stamped or imprinted with a legend in substantially the
     following form:

               THIS WARRANT AND THE SHARE OF COMMON STOCK ISSUABLE UPON EXERCISE
               HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,
               AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE SECURITIES LAWS
               AND MAY NOT BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS
               REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE
               SECURITIES LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF
               ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
               SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
               SECURITIES LAWS IS NOT REQUIRED.

<PAGE>


          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants.

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through the Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at
all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any



<PAGE>


federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

          (i) not permit the par value, if any, of its Common Stock to exceed
     the then effective Warrant Price,

          (ii) no amend or modify an provision of the Certificate of
     Incorporation or by-laws of the Issuer in any manner that would adversely
     affect in any way the powers, preferences or relative participating,
     optional or other special rights of the Common Stock or which would
     adversely affect the rights of the Holders of the Warrants,

          (iii) take all such action as may be reasonably necessary in order
     that the Issuer may validly and legally issue fully paid and nonassessable
     shares of Common Stock, free and clear of any liens, claims, encumbrances
     and restrictions (other than as provided herein) upon the exercise of this
     Warrant, and

          (iv) use its best efforts to obtain all such authorizations,
     exemptions or consents from any public regulatory body having jurisdiction
     thereof as may be reasonably necessary to enable the Issuer to perform its
     obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such




<PAGE>


Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

          (a) Recapitalization, Reorganization, Reclassification, Consolidation,
     Merger or Sale.

          (i) In case the Issuer after the Original Issue Date shall do any of
     the following (each, a "Triggering Event"):

               (a) consolidate with or merge into any other Person and the
          Issuer shall not be the continuing or surviving corporation of such
          consolidation or merger, or

               (b) permit any other Person to consolidate with or merge into the
          Issuer and the Issuer shall be the continuing or surviving Person but,
          in connection with such consolidation or merger, any Capital Stock of
          the Issuer shall be changed into or exchanged for Securities of any
          other Person or cash or any other property, or

               (c) transfer all or substantially all of its properties or assets
          to any other Person, or

               (d) effect a capital reorganization or reclassification of its
          Capital Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such
Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the

<PAGE>


adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

     (ii) Notwithstanding anything contained in this Warrant to the contrary,
the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than the Issuer) which may be required
to deliver any Securities, cash or property upon the exercise of this Warrant as
provided herein shall assume, by written instrument delivered to, and reasonably
satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer
under this Warrant (and if the Issuer shall survive the consummation of such
Triggering Event, such assumption shall be in addition to, and shall not release
the Issuer from, and continuing obligations of the Issuer under this Warrant)
and (B) the obligation to deliver to such Holder such shares of Securities, cash
or property as, in accordance with the foregoing provisions of this subsection
(a), such Holder shall be entitled to receive, and such Person shall have
similarly delivered to such Holder an opinion of counsel for such Person, which
counsel shall be reasonably satisfactory to such holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of the subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to delivery upon any exercise of this Warrant or the exercise of any
rights pursuant hereto.

     (iii) If with respect to any Triggering Event, the Holder of this Warrant
has exercised its right as provided in clause (y) of subparagraph (i) of this
subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees that
as a condition to the consummation of any such Triggering Event the Issuer shall
secure such right of Holder to sell this Warrant to the Person continuing after
or surviving such Triggering Event and the Issuer shall not effect any such
Triggering Event unless upon or prior to the consummation thereof the amounts of
cash, property and/or Securities required under such clause (y) are delivered to
the Holder of this Warrant. The obligation of the Issuer to secure such right of
the Holder to sell this Warrant shall be subject to such Holder's cooperation
with the Issuer, including, without limitation, the giving of customary
representations and warranties to the purchaser in connection with any such
sale. Prior notice of any Triggering Event shall be given to the Holder of this
Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a


<PAGE>


result of such subdivision, or (ii) in the case of a combination of shares, the
Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of Holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately




<PAGE>


after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.


<PAGE>


          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>


     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

     7. Definitions. For the purposes of this Warrant, the following terms have
the following meanings:

provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

          (i) not permit the par value, if any, of its Common Stock to exceed
     the then effective Warrant Price,

          (ii) no amend or modify an provision of the Certificate of
     Incorporation or by-laws of the Issuer in any manner that would adversely
     affect in any way the powers, preferences or relative participating,
     optional or other special rights of the Common Stock or which would
     adversely affect the rights of the Holders of the Warrants,

          (iii) take all such action as may be reasonably necessary in order
     that the Issuer may validly and legally issue fully paid and nonassessable
     shares of Common Stock, free and clear of any liens, claims, encumbrances
     and restrictions (other than as provided herein) upon the exercise of this
     Warrant, and

          (iv) use its best efforts to obtain all such authorizations,
     exemptions or consents from any public regulatory body having jurisdiction
     thereof as may be reasonably necessary to enable the Issuer to perform its
     obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such




<PAGE>


Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

          (a) Recapitalization, Reorganization, Reclassification, Consolidation,
     Merger or Sale.

          (i) In case the Issuer after the Original Issue Date shall do any of
     the following (each, a "Triggering Event"):

               (a) consolidate with or merge into any other Person and the
          Issuer shall not be the continuing or surviving corporation of such
          consolidation or merger, or

               (b) permit any other Person to consolidate with or merge into the
          Issuer and the Issuer shall be the continuing or surviving Person but,
          in connection with such consolidation or merger, any Capital Stock of
          the Issuer shall be changed into or exchanged for Securities of any
          other Person or cash or any other property, or

               (c) transfer all or substantially all of its properties or assets
          to any other Person, or

               (d) effect a capital reorganization or reclassification of its
          Capital Stock,

then, and in the case of each such Triggering  Event,  proper provision shall be
made so that,  upon the basis and the terms and in the manner  provided  in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time  after the  consummation  of such  Triggering  Event,  to the
extent this  Warrant is not  exercised  prior to such  Triggering  Event,  or is
redeemed in connection  with such  Triggering  Event,  to receive at the Warrant
Price in  effect  at the time  immediately  prior  to the  consummation  of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering  Event,  the  Securities,  cash and property to
which  such  Holder  would  have been  entitled  upon the  consummation  of such
Triggering  Event if such Holder had  exercised the rights  represented  by this
Warrant  immediately  prior  thereto,   subject  to  adjustments  and  increases
(subsequent to such corporate action) as nearly equivalent as possible to the


<PAGE>


adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

          (ii) Notwithstanding anything contained in this Warrant to the
     contrary, the Issuer will not effect any Triggering Event unless, prior to
     the consummation thereof, each Person (other than the Issuer) which may be
     required to deliver any Securities, cash or property upon the exercise of
     this Warrant as provided herein shall assume, by written instrument
     delivered to, and reasonably satisfactory to, the Holder of this Warrant,
     (A) the obligations of the Issuer under this Warrant (and if the Issuer
     shall survive the consummation of such Triggering Event, such assumption
     shall be in addition to, and shall not release the Issuer from, and
     continuing obligations of the Issuer under this Warrant) and (B) the
     obligation to deliver to such Holder such shares of Securities, cash or
     property as, in accordance with the foregoing provisions of this subsection
     (a), such Holder shall be entitled to receive, and such Person shall have
     similarly delivered to such Holder an opinion of counsel for such Person,
     which counsel shall be reasonably satisfactory to such holder, stating that
     this Warrant shall thereafter continue in full force and effect and the
     terms hereof (including, without limitation, all of the provisions of the
     subsection (a)) shall be applicable to the Securities, cash or property
     which such Person may be required to delivery upon any exercise of this
     Warrant or the exercise of any rights pursuant hereto.

          (iii) If with respect to any Triggering Event, the Holder of this
     Warrant has exercised its right as provided in clause (y) of subparagraph
     (i) of this subsection (a) to sell this Warrant or a portion thereof, the
     Issuer agrees that as a condition to the consummation of any such
     Triggering Event the Issuer shall secure such right of Holder to sell this
     Warrant to the Person continuing after or surviving such Triggering Event
     and the Issuer shall not effect any such Triggering Event unless upon or
     prior to the consummation thereof the amounts of cash, property and/or
     Securities required under such clause (y) are delivered to the Holder of
     this Warrant. The obligation of the Issuer to secure such right of the
     Holder to sell this Warrant shall be subject to such Holder's cooperation
     with the Issuer, including, without limitation, the giving of customary
     representations and warranties to the purchaser in connection with any such
     sale. Prior notice of any Triggering Event shall be given to the Holder of
     this Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a combination of shares, the




<PAGE>


Warrant Price shall be proportionately increased (as at the effective date of
such combination or, if the Issuer shall take a record of Holders of its Common
Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately




<PAGE>


after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.




<PAGE>


          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>


     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

Warrant may be amended, or compliance therewith may be waived (either generally

     12. Remedies. The Issuer stipulates that the remedies at law of the Holder
of this Warrant in the event of any default or threatened default by the Issuer
in the performance of or compliance with any of the terms of this Warrant are
not and will not be adequate and that, to the fullest extent permitted by law,
such terms may be specifically enforced by a decree for the specific performance
of any agreement contained herein or by an injunction against a violation of any
of the terms hereof or otherwise.

     13. Successors and Assigns. This Warrant and the rights evidenced hereby
shall inure to the benefit of and be binding upon the successors and assigns of
the Issuer, the Holder hereof and (to the extent provided herein) the Holders of
Warrant Stock issued pursuant hereto, and shall be enforceable by any such
Holder or Holder of Warrant Stock.

     14. Modification and Severability. If, in any action before any court or
agency legally empowered to enforce any provision contained herein, any
provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     15. Headings. The headings of the Sections of this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

     IN WITNESS WHEREOF, the Issuer has executed this Warrant as of the day and
year first above written.

THE WARRANT REPRESENTED BY THIS CERTIFICATE AND THE SHARES OF COMMON STOCK
ISSUABLE UPON THE EXERCISE OF THE WARRANT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR REGISTERED OR QUALIFIED UNDER
THE SECURITIES LAWS OF ANY STATE AND THUS MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED UNLESS REGISTERED UNDER THAT ACT AND REGISTERED OR QUALIFIED UNDER
APPLICABLE SECURITIES LAW OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION OR
QUALIFICATION IS AVAILABLE.


              WARRANT TO PURCHASE 25,000 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                              FROM DECEMBER 1, 1999
           VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON DECEMBER 1, 2001


     This certifies that, IIG Capital LLC or registered assigns, is entitled,
subject to the terms set forth below, to purchase from Pollution Research and
Control Corp., a California corporation (the "Company"), the above number of
fully paid and nonassessable shares of Common Stock of the Company ("Common
Stock") at a purchase price of One Dollar and fifty cents ($1.50) per share
("Purchase Price"). The Purchase Price and number of shares of Common Stock
issuable upon exercise hereof shall be subject to adjustment as provided in this
Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on December 10, 2001.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.


<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of



<PAGE>


such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.


<PAGE>


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up shall take place. That notice shall also specify the


<PAGE>


date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).

8. COVENANTS.

     The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

<PAGE>


10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

15. AMENDMENT.

     This Warrant and any of its terms may be changed only by a written
instrument signed by the Company and the holder of this Warrant.

TRANSFERRED UNLESS REGISTERED UNDER THAT ACT AND REGISTERED OR QUALIFIED UNDER
APPLICABLE SECURITIES LAW OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION OR

              WARRANT TO PURCHASE 20,475 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                               FROM JULY 16, 1999
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON JULY 16, 2002


     This certifies that, Phillip T. Huss or registered assigns, is entitled,
subject to the terms set forth below, to purchase from Pollution Research and
Control Corp., a California corporation (the "Company"), the above number of
fully paid and nonassessable shares of Common Stock of the Company ("Common
Stock") at a purchase price of Seventy Five Cents ($.75) per share ("Purchase
Price"). The Purchase Price and number of shares of Common Stock issuable upon
exercise hereof shall be subject to adjustment as provided in this Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on July 16, 2002, unless sooner exercise
is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.



<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of



<PAGE>


such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

<PAGE>


10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

15. AMENDMENT.

              WARRANT TO PURCHASE 54,525 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                               FROM JULY 16, 1999
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON JULY 16, 2002


     This certifies that, Ronald E. Patterson or registered assigns, is
entitled, subject to the terms set forth below, to purchase from Pollution
Research and Control Corp., a California corporation (the "Company"), the above
number of fully paid and nonassessable shares of Common Stock of the Company
("Common Stock") at a purchase price of Seventy Five Cents ($.75) per share
("Purchase Price"). The Purchase Price and number of shares of Common Stock
issuable upon exercise hereof shall be subject to adjustment as provided in this
Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on July 16, 2002, unless sooner exercise
is required pursuant to the terms of this Warrant.

     DEFINITIONS.

requires, have the following meanings:

obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the

<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of


<PAGE>


such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

ISSUABLE UPON THE EXERCISE OF THE WARRANT HAVE NOT BEEN REGISTERED UNDER THE

              WARRANT TO PURCHASE 20,000 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                              FROM AUGUST 12, 1999
           VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON AUGUST 12, 2002


     This certifies that, Fidelity Funding Inc. or registered assigns, is
entitled, subject to the terms set forth below, to purchase from Pollution
Research and Control Corp., a California corporation (the "Company"), the above
number of fully paid and nonassessable shares of Common Stock of the Company
("Common Stock") at a purchase price of Seventy Five Cents ($.75) per share
("Purchase Price"). The Purchase Price and number of shares of Common Stock
issuable upon exercise hereof shall be subject to adjustment as provided in this
Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on August 12, 2002, unless sooner
exercise is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.



<PAGE>

     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of


<PAGE>


such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.

<PAGE>


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up shall take place. That notice shall also specify the



<PAGE>


date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

and the registration and qualification requirements under applicable state law.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes

respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

meetings of shareholders, to receive dividends or subscription rights or
otherwise.

payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of




<PAGE>


such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>

6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

<PAGE>


10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.


15. AMENDMENT.

instrument signed by the Company and the holder of this Warrant.

              WARRANT TO PURCHASE 25,000 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                             FROM SEPTEMBER 13, 1999
          VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON SEPTEMBER 13, 2002


     This certifies that, Lee Sion or registered assigns, is entitled, subject
to the terms set forth below, to purchase from Pollution Research and Control
Corp., a California corporation (the "Company"), the above number of fully paid
and nonassessable shares of Common Stock of the Company ("Common Stock") at a
purchase price of Two Dollars and 40 cents ($2.40) per share ("Purchase Price").
The Purchase Price and number of shares of Common Stock issuable upon exercise
hereof shall be subject to adjustment as provided in this Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on September 13, 2002, unless sooner
exercise is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.



<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of



<PAGE>


such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).

     8. COVENANTS.

     The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

<PAGE>


10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes

THE  WARRANT  REPRESENTED  BY THIS  CERTIFICATE  AND THE SHARES OF COMMON  STOCK
ISSUABLE  UPON THE  EXERCISE OF THE WARRANT HAVE NOT BEEN  REGISTERED  UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR REGISTERED OR QUALIFIED UNDER
THE SECURITIES LAWS OF ANY STATE AND THUS MAY NOT BE OFFERED,  SOLD OR OTHERWISE
TRANSFERRED  UNLESS  REGISTERED UNDER THAT ACT AND REGISTERED OR QUALIFIED UNDER
APPLICABLE  SECURITIES  LAW OR UNLESS AN  EXEMPTION  FROM SUCH  REGISTRATION  OR

              WARRANT TO PURCHASE 25,000 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                             FROM SEPTEMBER 13, 1999
          VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON SEPTEMBER 13, 2002


     This certifies that, Steven Sion or registered assigns, is entitled,
subject to the terms set forth below, to purchase from Pollution Research and
Control Corp., a California corporation (the "Company"), the above number of
fully paid and nonassessable shares of Common Stock of the Company ("Common
Stock") at a purchase price of Two Dollars and 40 cents ($2.40) per share
("Purchase Price"). The Purchase Price and number of shares of Common Stock
issuable upon exercise hereof shall be subject to adjustment as provided in this
Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on September 13, 2002, unless sooner
exercise is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.



<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of




<PAGE>


such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).

8. COVENANTS.

     The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

<PAGE>


10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.


15. AMENDMENT.

     This Warrant and any of its terms may be changed only by a written
instrument signed by the Company and the holder of this Warrant.

covered by such Registration Statement have been sold or (y) the date on which
the Registrable Securities may be sold without any restriction pursuant to Rule
144(k) as determined by the counsel to the Company pursuant to a written opinion
letter, addressed to the Company's transfer agent to such effect (the
"Effectiveness Period"). If the Company is notified orally or in writing by the
Commission that the Commission has no comments with respect to the Registration
Statement (the "Commission Notice"), the Company shall use its best efforts to
cause the Registration Statement to be declared effective no later than five (5)
business days after receipt of the Commission Notice. If an additional
Registration Statement is required to be filed because the actual number of
shares of Common Stock into which the Warrants are exercisable exceeds the
number of shares of Common Stock initially registered in respect of the
Conversion Shares and the Warrant Shares based upon the computation on the




<PAGE>


Closing Date, the Company shall have twenty (20) Business Days to file such
additional Registration Statement, and the Company shall use its best efforts to
cause such additional Registration Statement to be declared effective by the
Commission as soon as possible, but in no event later than forth-five (45) days
after filing.

     3. Registration Procedures.

          In connection with the Company's registration obligations hereunder,
the Company shall:

          (a) Prepare and file with the Commission on or prior to the Filing
Date, a Registration Statement on Form S-3 (or if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith) in
accordance with the method or methods of distribution thereof as specified by
the Holders (except if otherwise directed by the Holders), and cause the
Registration Statement to become effective and remain effective as provided
herein; provided, however, that not less than five (5) Business Days prior to
the filing of the Registration Statement or any related Prospectus or any
amendment or supplement thereto (including any document that would be
incorporated therein by reference), the Company shall (i) furnish to the Holders
and any Special Counsel, copies of all such documents proposed to be filed,
which documents (other than those incorporated by reference) will be subject to
the review of such Holders and such Special Counsel, and (ii) at the request of
any Holder cause its officers and directors, counsel and independent certified
public accountants to respond to such inquiries as shall be necessary, in the
reasonable opinion of counsel to such Holders, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file the Registration Statement or any such Prospectus or any amendments or
supplements thereto to which the Holders of a majority of the Registrable
Securities or any Special Counsel shall reasonably object in writing within
three (3) Business Days of their receipt thereof.

          (b) (i) Prepare and file with the Commission such amendments,
including post- effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as possible provide the Holders true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

<PAGE>


          (c) Notify the Holders of Registrable Securities to be sold and any
Special Counsel as promptly as possible (and, in the case of (i)(A) below, not
less than five (5) Business Days prior to such filing) and (if requested by any
such Person) confirm such notice in writing no later than one (1) Business Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to the Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement and (C) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

          (d) Use its best efforts to avoid the issuance of, or if issued,
obtain the withdrawal of, (i) any order suspending the effectiveness of the
Registration Statement or (ii) any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction, at the earliest practicable moment.

          (e) If requested by the Holders of a majority in interest of the
Registrable Securities, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as the
Company reasonably agrees should be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon
as practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment.

          (f) Furnish to each Holder and any Special Counsel, without charge, at
least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

<PAGE>


          (g) Promptly deliver to each Holder and any Special Counsel, without
charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

          (h) Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
any Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

          (i) Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold
pursuant to a Registration Statement, which certificates shall be free of all
restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any Holder may request at least
two (2) Business Days prior to any sale of Registrable Securities.

          (j) Upon the occurrence of any event contemplated by Section 3(c)(vi),
as promptly as possible, prepare a supplement or amendment, including a
post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

          (k) Use its best efforts to cause all Registrable Securities relating
to such Registration Statement to be listed on the Nasdaq Small Cap Market and
any other securities exchange, quotation system, market or over-the-counter
bulletin board, if any, on which similar securities issued by the Company are
then listed as and when required pursuant to the Purchase Agreement.

          (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions os Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period (or 90 days after the end of any 12-month period if such period is a




<PAGE>


fiscal year) commencing on the first day of the first fiscal quarter of the
Company after the effective date of the Registration Statement, which statement
shall conform to the requirements of Rule 158.

          (m) The Company may require each selling Holder to furnish to the
Company information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement, and the Company may exclude from such registration the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until Such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

          (n) If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may postpone or suspend its
obligation under this Section 3(n) for more than 45 days in the aggregate during
any 12 month period (each, a "Blackout Period"); provided, however, that no such
postponement or suspension shall be permitted for consecutive 20 day periods,
arising out of the same set of facts, circumstances or transactions.

     4. Registration Expenses

          All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by the Company whether or not
the Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with the OTC
Bulletin Board and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed, (B) with respect to filings
required to be made with the Commission, (C) with respect to filings required to
be made under Nasdaq SmallCap Market Rules and (C) in compliance with state
securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel for the Holders in connection with Blue Sky
qualifications of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such
jurisdictions as the Holders of a majority of Registrable Securities may
designate)), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses if
the printing of prospectuses is requested by the holders of a majority of the
Registrable Securities included in the Registration Statement), (iii) messenger,
telephone and delivery expenses, (iv) fees and disbursements of counsel for the
Company and Special Counsel for the Holders, in the case of the Special Counsel,
to a maximum amount of $10,000, (v) Securities Act liability insurance, if the
Company so desires such insurance, and (vi) fees and expenses of all other
Persons retained by the Company in connection with the consummation of the
transactions contemplated by this Agreement, including, without limitation, the
Company's independent public accountants (including the expenses of any comfort
letters or costs associated with the delivery by independent public accountants
of a comfort letter or comfort letters). In addition, the Company shall be
responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder.


     5. Indemnification

          (a) Indemnification by the Company. The Company shall, notwithstanding
any termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, agents, brokers (including brokers who offer and sell
Registrable Securities as principal as a result of a pledge or any failure to
perform under a margin call of Common Stock), investment advisors and employees
of each of them, each Person who controls any such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, to
the fullest extent permitted by applicable law, from and against any and all
losses, claims, damages, liabilities, costs (including, without limitation,



<PAGE>


costs of preparation and attorneys' fees) and expenses (collectively, "Losses"),
as incurred, arising out of or relating to any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except to the extent, but only to the
extent, that such untrue statements or omissions are based solely upon
information regarding such Holder furnished in writing to the Company by such
Holder expressly for use therein, which information was reasonably relied on by
the Company for use therein or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus or in any amendment or supplement thereto. The Company shall notify
the Holders promptly of the institution, threat or assertion of any Proceeding
of which the Company is aware in connection with the transactions contemplated
by this Agreement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of an Indemnified Party and
shall survive the transfer of the Registrable Securities by the Holders.

          (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, the directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely out of or based solely upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus, or arising solely out of or based solely upon any omission
of a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in the Registration
Statement or such Prospectus and that such information was reasonably relied
upon by the Company for use in the Registration Statement, such Prospectus or
such form of prospectus or to the extent that such information relates to such
Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus. Notwithstanding anything to the contrary contained herein, the
Holder shall be liable under this Section 5(b) for only that amount as does not
exceed the net proceeds to such Holder as a result of the sale of Registrable
Securities pursuant to such Registration Statement.

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment



<PAGE>


of counsel reasonably satisfactory to the Indemnified Party and the payment of
all fees and expenses incurred in connection with defense thereof; provided,
that the failure of any Indemnified Party to give such notice shall not relieve
the Indemnifying Party of its obligations or liabilities pursuant to this
Agreement, except (and only) to the extent that it shall be finally determined
by a court of competent jurisdiction (which determination is not subject to
appeal or further review) that such failure shall have proximately and
materially adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within then (10)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

          (d) Contribution. If a claim for indemnification under Section 5(a) or
5(b) is unavailable to an Indemnified Party because of a failure or result of a
governmental authority to enforce such indemnification in accordance with its
terms (by reason of public policy or otherwise), then each Indemnifying Party,
in lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such Losses, in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and Indemnified Party in connection with the actions, statements or
omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified



<PAGE>


Party shall be determined by reference to, among other things, whether any
action in question, including any untrue or alleged untrue statement of a
material fact or omission or alleged omission of a material fact, has been taken
or made by, or relates to information supplied by, such Indemnifying Party, or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action, statement or
omission. The amount paid or payable by a party as a result of any Losses shall
be deemed to include, subject to the limitations set forth in Section 5(c), any
reasonable attorneys' or other reasonable fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for in
this Section was available to such party in accordance with its terms.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable or required to contribute under this Section 5(c) for only that amount as
does not exceed the net proceeds to such Holder as a result of the sale of
Registrable Securities pursuant to such Registration Statement.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

     6. Rule 144.

          As long as any Holder owns Common Stock, Warrants or Warrant Shares,
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act and to promptly furnish the Holders with true and complete copies
of all such filings. As long as any Holder owns Common Stock, Warrants or
Warrant Shares, if the Company is not required to file reports pursuant to
Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the
Holders and make publicly available in accordance with Rule 144(c) promulgated
under the Securities Act annual and quarterly financial statements, together
with a discussion and analysis of such financial statements in form and
substance substantially similar to those that would otherwise be required to
have been made under the Exchange Act. The Company further covenants that it
will take such further action as any Holder may reasonably request, all to the
extent required from time to time to enable such Person to sell Common Stock and
Warrant Shares without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act, including providing any legal opinions referred to in the
Purchase Agreement. Upon the request of any Holder, the Company shall deliver to
such Holder a written certification of a duly authorized officer as to whether
it has complied with such requirements.

     7. Miscellaneous.

          (a) Remedies. In the event of a breach by the Company or by a Holder,
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

          (b) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof entered into and currently in effect,
nor shall the Company or any of its subsidiaries, on or after the date of this
Agreement, enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. Without limiting the generality
of the foregoing, without the written consent of the Holders of a majority of
the then outstanding Registrable Securities, the Company shall not grant to any
Person the right to request the Company to register any securities of the
Company under the Securities Act unless the right so granted are subject in all
respects to the prior rights in full of the Holders set forth herein, and are
not otherwise in conflict with the provisions of this Agreement, or the
Registration Rights Agreement has been declared effective by the SEC.

          (c) No Piggyback on Registrations. Neither the Company nor any of its
security holders (other than the Holders in such capacity pursuant hereto and
the Persons listed on Schedule 7(c) hereto) may include securities of the
Company in the Registration Statement, and the Company shall not after the date
hereof enter into any agreement providing such right to any of its security
holders, unless the right so granted is subject in all respects to the prior
rights in full of the Holders set forth herein, and is not otherwise in conflict
with the provisions of this Agreement.

          (d) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering (i) the Shares of Common Stock or (ii)
the Warrant Shares, the Company shall determine to prepare and file with the
Commission a registration statement relating to an offering for its own account
or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or its then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, the Company shall send to each holder of Registrable Securities
written notice of such determination and, if within thirty (30) days after
receipt of such notice, any such holder shall so request in writing (which
request shall specify the Registrable Securities intended to be disposed of by
the Purchasers), the Company will cause the registration under the Securities
Act of all Registrable Securities which the Company has been so requested to
register by the holder, to the extent requisite to permit the disposition of the
Registrable Securities so to be registered, provided that if at any time after
giving written notice of its intention to register any securities and prior to



<PAGE>


the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to
delay registration of such securities, the Company may, at its election, give
written notice of such determination to such holder and, thereupon, (i) in the
case of a determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay expenses in accordance with Section 4 hereof),
and (ii) in the case of a determination to delay registering, shall be permitted
to delay registering any Registrable Securities being registered pursuant to
this Section 7(d) for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such holder requests to be registered;
provided, however, that the Company shall not be required to register any
Registrable Securities pursuant to this Section 7(d) that are eligible for sale
pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten
public offering, if the managing underwriter(s) or underwriter(s) should
reasonably object to the inclusion of the Registrable Securities in such
registration statement, then if the Company after consultation with the managing
underwriter should reasonably determine that the inclusion of such Registrable
Securities, would materially adversely affect the offering contemplated in such
registration statement, and based on such determination recommends inclusion in
such registration statement of fewer or none of the Registrable Securities of
the Holders, then (x) the number of Registrable Securities of the Holders
included in such registration statement shall be reduced pro-rata among such
Holders (based upon the number of Registrable Securities requested to be
included in the registration), if the Company after consultation with the
underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y)
none of the Registrable Securities of the Holders shall be included in such
registration statement, if the Company after consultation with the
underwriter(s) recommends the inclusion of none of such Registrable Securities;
provided, however, that if securities are being offered for the account of other
persons or entities as well as the Company, such reduction shall not represent a
greater fraction of the number of Registrable Securities intended to be offered
by the Holders than the fraction of similar reductions imposed on such other
persons or entities (other than the Company).

          (e) Failure to File Registration Statement and Other Events. The
Company and the Purchasers agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Time or if
certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (i) the Registration Statement is not filed on or prior to the
Filing Date, (or is not declared effective by the Commission on or prior to the
Effectiveness Date or in the event an additional Registration Statement is filed
because the actual number of shares of Common Stock into which the Warrants are
exercisable exceeds the number of shares of Common Stock initially registered is
not filed and declared effective within the time periods set forth in Section
2(a)), or (ii) the Company fails to file with the Commission a request for
acceleration in accordance with Rule 12dl-2 promulgated under the Exchange Act
within five (5) Business Days of the date that the Company is notified (orally
or in writing, whichever is earlier) by the Commission that a Registration
Statement will not be "reviewed," or not subject to further review, or (iii) the
Registration Statement is filed with and declared effective by the Commission




<PAGE>


but thereafter ceases to be effective as to all Registrable Securities at any
time prior to the expiration of the Effectiveness Period, without being
succeeded immediately by a subsequent Registration Statement filed with and
declared effective by the Commission, and such cessation continues for a period
of thirty days after written notice thereof to the Company, or (iv) trading in
the Common Stock shall be suspended or if the Common Stock is delisted from the
Nasdaq SmallCap Market for any reason for more than three Business Days in the
aggregate, and such suspension or delisting continues for a period of fourteen
days after written notice thereof to the Company, or (v) the Company breaches in
a material respect any covenant or other material term or condition to this
Agreement, Purchase Agreement (other than a representation or warranty contained
therein) or any other agreement, document, certificate or other instrument
delivered in connection with the transactions contemplated hereby and thereby,
and such breach continues for a period of thirty days after written notice
thereof to the Company, or (vii) the Company has breached Section 3(n) of this
Agreement (any such failure or breach being referred to as an ("Event"), the
Company shall pay in cash as liquidated damages for such failure and not as a
penalty to each Holder an amount equal to 2% of such Holder's pro rata share of
the purchase price paid by all Holders for all shares of Common Stock purchased
and then outstanding pursuant to the Purchase Agreement for each thirty (30) day
period until the applicable Event has been cured, which shall be pro rated for
such periods less than thirty (30) days (the "Periodic Amount"). Payments to be
made pursuant to this Section 7(e) shall be due and payable in cash immediately
upon demand. The parties agree that the Periodic Amount represents a reasonable
estimate on the part of the parties, as of the date of this Agreement, of the
amount of damages that may be incurred by the Holders if the Registration
Statement is not filed on or prior to the Filing Date or has not been declared
effective by the Commission on or prior to the Effectiveness Date and maintained
in the manner contemplated herein during the Effectiveness Time or if any other
Event as described herein has occurred.

               (i) The Company and the Purchasers acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this

accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Registration
Rights Agreement or the Purchase Agreement and to enforce specifically the terms
and provisions hereof or thereof, this being in addition to any other remedy to
which any of them may be entitled by law or equity.

               (ii) Each of the Company and the Purchasers (i) hereby
irrevocably submits to the jurisdiction of the United States District Court
sitting in the Southern District of New York for the purposes of any suit,
action or proceeding arising out of or relating to this Agreement or the
Purchase Agreement and (ii) hereby waives, and agrees not to assert in any such
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is improper.
Each of the Company and the Purchasers consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 7(f) shall affect or limit any right to serve
process in any other manner permitted by law.

Ladies and Gentlemen:

          We are counsel to Pollution Research and Control Corp., a California
corporation (the "Company"), and have represented the Company in connection with
(i) that certain Debenture (the "Debenture") issued by the Company in favor of
The Venezuela Recovery Fund, N.V. (the "Holder") which Debenture is convertible
into shares of the Company's common stock, par value $.01 per share (the "Common
Stock"), and (ii) warrants issued to the Holder to purchase shares of the Common
Stock (the "Warrants"). Pursuant to the Debenture, the Company also has entered
into a Registration Rights Agreement with the Holder (the "Registration Rights
Agreement") pursuant to which the Company agreed, among other things, to
register the Registrable Securities (as defined the Registration Rights
Agreement), including the shares of Common Stock issuable upon exercise of the
Warrants, under the Securities Act of 1933, as amended (the "1933 Act"). In
connection with the Company's obligations under the Registration Rights
Agreement, on _______ __, 1999, the Company filed a Registration Statement on
Form S-3 (File No. 333-____________) (the "Registration Statement") with the
Securities and Exchange Commission (the "SEC") relating to the Registrable
Securities which names each of the Holders as a selling stockholder thereunder.

          In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                              Very truly yours,

                                              [COMPANY'S COUNSEL]



                                              By:_______________________________

cc:  The Venezuela Recovery Fund, N.V.

eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith) in
accordance with the method or methods of distribution thereof as specified by
the Holders (except if otherwise directed by the Holders), and cause the
Registration Statement to become effective and remain effective as provided

incorporated therein by reference), the Company shall (i) furnish to the Holders
and any Special Counsel, copies of all such documents proposed to be filed,
which documents (other than those incorporated by reference) will be subject to
the review of such Holders and such Special Counsel, and (ii) at the request of
any Holder cause its officers and directors, counsel and independent certified
public accountants to respond to such inquiries as shall be necessary, in the
reasonable opinion of counsel to such Holders, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file the Registration Statement or any such Prospectus or any amendments or
supplements thereto to which the Holders of a majority of the Registrable
Securities or any Special Counsel shall reasonably object in writing within
three (3) Business Days of their receipt thereof.

          (b) (i) Prepare and file with the Commission such amendments,
including post- effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as possible provide the Holders true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

<PAGE>

          (c) Notify the Holders of Registrable Securities to be sold and any
Special Counsel as promptly as possible (and, in the case of (i)(A) below, not
less than five (5) Business Days prior to such filing) and (if requested by any
such Person) confirm such notice in writing no later than one (1) Business Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to the Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement and (C) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

          (d) Use its best efforts to avoid the issuance of, or if issued,
obtain the withdrawal of, (i) any order suspending the effectiveness of the
Registration Statement or (ii) any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction, at the earliest practicable moment.

          (e) If requested by the Holders of a majority in interest of the
Registrable Securities, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as the
Company reasonably agrees should be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon
as practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment.

          (f) Furnish to each Holder and any Special Counsel, without charge, at
least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

<PAGE>


          (g) Promptly deliver to each Holder and any Special Counsel, without
charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

          (h) Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
any Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

          (i) Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold
pursuant to a Registration Statement, which certificates shall be free of all
restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any Holder may request at least
two (2) Business Days prior to any sale of Registrable Securities.

          (j) Upon the occurrence of any event contemplated by Section 3(c)(vi),
as promptly as possible, prepare a supplement or amendment, including a
post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

          (k) Use its best efforts to cause all Registrable Securities relating
to such Registration Statement to be listed on the Nasdaq Small Cap Market and
any other securities exchange, quotation system, market or over-the-counter
bulletin board, if any, on which similar securities issued by the Company are
then listed as and when required pursuant to the Purchase Agreement.

          (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions os Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period (or 90 days after the end of any 12-month period if such period is a




<PAGE>


fiscal year) commencing on the first day of the first fiscal quarter of the
Company after the effective date of the Registration Statement, which statement
shall conform to the requirements of Rule 158.

          (m) The Company may require each selling Holder to furnish to the
Company information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement, and the Company may exclude from such registration the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until Such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

          (n) If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may postpone or suspend its
obligation under this Section 3(n) for more than 45 days in the aggregate during
any 12 month period (each, a "Blackout Period"); provided, however, that no such
postponement or suspension shall be permitted for consecutive 20 day periods,
arising out of the same set of facts, circumstances or transactions.

     4. Registration Expenses

          All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by the Company whether or not
the Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with the OTC
Bulletin Board and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed, (B) with respect to filings
required to be made with the Commission, (C) with respect to filings required to
be made under Nasdaq SmallCap Market Rules and (C) in compliance with state
securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel for the Holders in connection with Blue Sky
qualifications of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such
jurisdictions as the Holders of a majority of Registrable Securities may
designate)), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses if
the printing of prospectuses is requested by the holders of a majority of the
Registrable Securities included in the Registration Statement), (iii) messenger,
telephone and delivery expenses, (iv) fees and disbursements of counsel for the
Company and Special Counsel for the Holders, in the case of the Special Counsel,
to a maximum amount of $10,000, (v) Securities Act liability insurance, if the
Company so desires such insurance, and (vi) fees and expenses of all other
Persons retained by the Company in connection with the consummation of the
transactions contemplated by this Agreement, including, without limitation, the
Company's independent public accountants (including the expenses of any comfort
letters or costs associated with the delivery by independent public accountants
of a comfort letter or comfort letters). In addition, the Company shall be
responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder.


     5. Indemnification

          (a) Indemnification by the Company. The Company shall, notwithstanding
any termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, agents, brokers (including brokers who offer and sell
Registrable Securities as principal as a result of a pledge or any failure to
perform under a margin call of Common Stock), investment advisors and employees
of each of them, each Person who controls any such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, to
the fullest extent permitted by applicable law, from and against any and all
losses, claims, damages, liabilities, costs (including, without limitation,



<PAGE>


costs of preparation and attorneys' fees) and expenses (collectively, "Losses"),
as incurred, arising out of or relating to any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except to the extent, but only to the
extent, that such untrue statements or omissions are based solely upon
information regarding such Holder furnished in writing to the Company by such
Holder expressly for use therein, which information was reasonably relied on by
the Company for use therein or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus or in any amendment or supplement thereto. The Company shall notify
the Holders promptly of the institution, threat or assertion of any Proceeding
of which the Company is aware in connection with the transactions contemplated
by this Agreement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of an Indemnified Party and
shall survive the transfer of the Registrable Securities by the Holders.

          (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, the directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely out of or based solely upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus, or arising solely out of or based solely upon any omission
of a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in the Registration
Statement or such Prospectus and that such information was reasonably relied
upon by the Company for use in the Registration Statement, such Prospectus or
such form of prospectus or to the extent that such information relates to such
Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus. Notwithstanding anything to the contrary contained herein, the
Holder shall be liable under this Section 5(b) for only that amount as does not
exceed the net proceeds to such Holder as a result of the sale of Registrable
Securities pursuant to such Registration Statement.

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the employment of



<PAGE>


counsel reasonably satisfactory to the Indemnified Party and the payment of all
fees and expenses incurred in connection with defense thereof; provided, that
the failure of any Indemnified Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally determined by a court
of competent jurisdiction (which determination is not subject to appeal or
further review) that such failure shall have proximately and materially
adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within then (10)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

          (d) Contribution. If a claim for indemnification under Section 5(a) or
5(b) is unavailable to an Indemnified Party because of a failure or result of a
governmental authority to enforce such indemnification in accordance with its
terms (by reason of public policy or otherwise), then each Indemnifying Party,
in lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such Losses, in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and Indemnified Party in connection with the actions, statements or
omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified



<PAGE>


Party shall be determined by reference to, among other things, whether any
action in question, including any untrue or alleged untrue statement of a
material fact or omission or alleged omission of a material fact, has been taken
or made by, or relates to information supplied by, such Indemnifying Party, or
Indemnified Party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such action, statement or
omission. The amount paid or payable by a party as a result of any Losses shall
be deemed to include, subject to the limitations set forth in Section 5(c), any
reasonable attorneys' or other reasonable fees or expenses incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for in
this Section was available to such party in accordance with its terms.
Notwithstanding anything to the contrary contained herein, the Holder shall be
liable or required to contribute under this Section 5(c) for only that amount as
does not exceed the net proceeds to such Holder as a result of the sale of
Registrable Securities pursuant to such Registration Statement.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

     6. Rule 144.

          As long as any Holder owns Common Stock, Warrants or Warrant Shares,
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act and to promptly furnish the Holders with true and complete copies
of all such filings. As long as any Holder owns Common Stock, Warrants or
Warrant Shares, if the Company is not required to file reports pursuant to
Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the
Holders and make publicly available in accordance with Rule 144(c) promulgated
under the Securities Act annual and quarterly financial statements, together
with a discussion and analysis of such financial statements in form and
substance substantially similar to those that would otherwise be required to
have been made under the Exchange Act. The Company further covenants that it
will take such further action as any Holder may reasonably request, all to the
extent required from time to time to enable such Person to sell Common Stock and
Warrant Shares without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act, including providing any legal opinions referred to in the
Purchase Agreement. Upon the request of any Holder, the Company shall deliver to
such Holder a written certification of a duly authorized officer as to whether
it has complied with such requirements.

     7. Miscellaneous.


          (a) Remedies. In the event of a breach by the Company or by a Holder,
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

          (b) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof entered into and currently in effect,
nor shall the Company or any of its subsidiaries, on or after the date of this
Agreement, enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. Without limiting the generality
of the foregoing, without the written consent of the Holders of a majority of
the then outstanding Registrable Securities, the Company shall not grant to any
Person the right to request the Company to register any securities of the
Company under the Securities Act unless the right so granted are subject in all
respects to the prior rights in full of the Holders set forth herein, and are
not otherwise in conflict with the provisions of this Agreement, or the
Registration Rights Agreement has been declared effective by the SEC.

          (c) No Piggyback on Registrations. Neither the Company nor any of its
security holders (other than the Holders in such capacity pursuant hereto and
the Persons listed on Schedule 7(c) hereto) may include securities of the
Company in the Registration Statement, and the Company shall not after the date
hereof enter into any agreement providing such right to any of its security
holders, unless the right so granted is subject in all respects to the prior
rights in full of the Holders set forth herein, and is not otherwise in conflict
with the provisions of this Agreement.

          (d) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering (i) the Shares of Common Stock or (ii)
the Warrant Shares, the Company shall determine to prepare and file with the
Commission a registration statement relating to an offering for its own account
or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or its then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, the Company shall send to each holder of Registrable Securities
written notice of such determination and, if within thirty (30) days after
receipt of such notice, any such holder shall so request in writing (which
request shall specify the Registrable Securities intended to be disposed of by
the Purchasers), the Company will cause the registration under the Securities
Act of all Registrable Securities which the Company has been so requested to
register by the holder, to the extent requisite to permit the disposition of the
Registrable Securities so to be registered, provided that if at any time after
giving written notice of its intention to register any securities and prior to



<PAGE>


the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to
delay registration of such securities, the Company may, at its election, give
written notice of such determination to such holder and, thereupon, (i) in the
case of a determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay expenses in accordance with Section 4 hereof),
and (ii) in the case of a determination to delay registering, shall be permitted
to delay registering any Registrable Securities being registered pursuant to
this Section 7(d) for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such holder requests to be registered;
provided, however, that the Company shall not be required to register any
Registrable Securities pursuant to this Section 7(d) that are eligible for sale
pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten
public offering, if the managing underwriter(s) or underwriter(s) should
reasonably object to the inclusion of the Registrable Securities in such
registration statement, then if the Company after consultation with the managing
underwriter should reasonably determine that the inclusion of such Registrable
Securities, would materially adversely affect the offering contemplated in such
registration statement, and based on such determination recommends inclusion in
such registration statement of fewer or none of the Registrable Securities of
the Holders, then (x) the number of Registrable Securities of the Holders
included in such registration statement shall be reduced pro-rata among such
Holders (based upon the number of Registrable Securities requested to be
included in the registration), if the Company after consultation with the
underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y)
none of the Registrable Securities of the Holders shall be included in such
registration statement, if the Company after consultation with the
underwriter(s) recommends the inclusion of none of such Registrable Securities;
provided, however, that if securities are being offered for the account of other
persons or entities as well as the Company, such reduction shall not represent a
greater fraction of the number of Registrable Securities intended to be offered
by the Holders than the fraction of similar reductions imposed on such other
persons or entities (other than the Company).

          (e) Failure to File Registration Statement and Other Events. The
Company and the Purchasers agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Time or if
certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (i) the Registration Statement is not filed on or prior to the
Filing Date, (or is not declared effective by the Commission on or prior to the
Effectiveness Date or in the event an additional Registration Statement is filed
because the actual number of shares of Common Stock into which the Warrants are
exercisable exceeds the number of shares of Common Stock initially registered is
not filed and declared effective within the time periods set forth in Section
2(a)), or (ii) the Company fails to file with the Commission a request for
acceleration in accordance with Rule 12dl-2 promulgated under the Exchange Act
within five (5) Business Days of the date that the Company is notified (orally
or in writing, whichever is earlier) by the Commission that a Registration
Statement will not be "reviewed," or not subject to further review, or (iii) the
Registration Statement is filed with and declared effective by the Commission



<PAGE>


but thereafter ceases to be effective as to all Registrable Securities at any
time prior to the expiration of the Effectiveness Period, without being
succeeded immediately by a subsequent Registration Statement filed with and
declared effective by the Commission, and such cessation continues for a period
of thirty days after written notice thereof to the Company, or (iv) trading in
the Common Stock shall be suspended or if the Common Stock is delisted from the
Nasdaq SmallCap Market for any reason for more than three Business Days in the
aggregate, and such suspension or delisting continues for a period of fourteen
days after written notice thereof to the Company, or (v) the Company breaches in
a material respect any covenant or other material term or condition to this
Agreement, Purchase Agreement (other than a representation or warranty contained
therein) or any other agreement, document, certificate or other instrument
delivered in connection with the transactions contemplated hereby and thereby,
and such breach continues for a period of thirty days after written notice
thereof to the Company, or (vii) the Company has breached Section 3(n) of this
Agreement (any such failure or breach being referred to as an ("Event"), the
Company shall pay in cash as liquidated damages for such failure and not as a
penalty to each Holder an amount equal to 2% of such Holder's pro rata share of
the purchase price paid by all Holders for all shares of Common Stock purchased
and then outstanding pursuant to the Purchase Agreement for each thirty (30) day
period until the applicable Event has been cured, which shall be pro rated for
such periods less than thirty (30) days (the "Periodic Amount"). Payments to be
made pursuant to this Section 7(e) shall be due and payable in cash immediately
upon demand. The parties agree that the Periodic Amount represents a reasonable
estimate on the part of the parties, as of the date of this Agreement, of the
amount of damages that may be incurred by the Holders if the Registration
Statement is not filed on or prior to the Filing Date or has not been declared
effective by the Commission on or prior to the Effectiveness Date and maintained
in the manner contemplated herein during the Effectiveness Time or if any other
Event as described herein has occurred.

          (f) Specific Enforcement, Consent to Jurisdiction.

               (i) The Company and the Purchasers acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Registration Rights Agreement or the Purchase Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Registration
Rights Agreement or the Purchase Agreement and to enforce specifically the terms
and provisions hereof or thereof, this being in addition to any other remedy to
which any of them may be entitled by law or equity.

               (ii) Each of the Company and the Purchasers (i) hereby
irrevocably submits to the jurisdiction of the United States District Court
sitting in the Southern District of New York for the purposes of any suit,
action or proceeding arising out of or relating to this Agreement or the
Purchase Agreement and (ii) hereby waives, and agrees not to assert in any such
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is improper.
Each of the Company and the Purchasers consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such
service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 7(f) shall affect or limit any right to serve
process in any other manner permitted by law.

<PAGE>

          (g) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and each of the Holders. Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders and that does not directly or indirectly
affect the rights of other Holders may be given by Holders of at least a
majority of the Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the
immediately preceding sentence.

          (h) Notices. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be in writing and shall be
deemed given and effective on the earlier of (i) the date of transmission, if
such notice or communication is delivered via facsimile at the facsimile
telephone number specified for notice prior to 5:00 p.m., eastern standard time,
on a Business Day, (ii) the Business Day after the date of transmission, if such
notice or communication is delivered via facsimile at the facsimile telephone
number specified for notice later than 5:00 p.m., eastern standard time, on any
date and earlier than 11:59 p.m., eastern standard time, on such date, (iii) the
Business Day following the date of mailing, if sent by nationally recognized
overnight courier service or (iv) actual receipt by the party to whom such
notice is required to be given. The addresses for such communications shall be
with respect to each Holder at its address set forth under its name on Schedule
A attached hereto, or with respect to the Company, addressed to:

Attn:__________________

                    Re: Pollution Research and Control Corp.

Ladies and Gentlemen:

          We are counsel to Pollution Research and Control Corp., a California
corporation (the "Company"), and have represented the Company in connection with
(i) that certain Debenture (the  "Debenture")  issued by the Company in favor of
The Venezuela  Recovery Fund, N.V. (the "Holder") which Debenture is convertible
into shares of the Company's common stock, par value $.01 per share (the "Common
Stock"), and (ii) warrants issued to the Holder to purchase shares of the Common
Stock (the "Warrants").  Pursuant to the Debenture, the Company also has entered
into a Registration  Rights Agreement with the Holder (the "Registration  Rights
Agreement")  pursuant  to which the  Company  agreed,  among  other  things,  to
register  the  Registrable   Securities  (as  defined  the  Registration  Rights
Agreement),  including the shares of Common Stock  issuable upon exercise of the
Warrants,  under the  Securities  Act of 1933,  as amended (the "1933 Act").  In
connection  with  the  Company's   obligations  under  the  Registration  Rights
Agreement,  on _______ __, 1999, the Company filed a  Registration  Statement on
Form S-3 (File No.  333-____________)  (the  "Registration  Statement") with the
Securities  and  Exchange  Commission  (the "SEC")  relating to the  Registrable
Securities which names each of the Holders as a selling stockholder thereunder.

          In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                           Very truly yours,

                                           [COMPANY'S COUNSEL]



                                           By:_______________________________

          (i) The Holder of this Warrant, by acceptance hereof, acknowledges
     that this Warrant or the shares of Warrant Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account and not as a
     nominee for any other party, and for investment, and that the Holder will
     not offer, sell or otherwise dispose of this Warrant or any shares of
     Warrant Stock to be issued upon exercise hereof except pursuant to an
     effective registration statement, or an exemption from registration, under

                    SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"),

                    TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER
                    THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES
                    LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF ITS
                    COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
                    SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE

<PAGE>


          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants.

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through the Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at
all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder


<PAGE>


require registration or qualification with any governmental authority under any
federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

          (i) not permit the par value, if any, of its Common Stock to exceed
     the then effective Warrant Price,

          (ii) no amend or modify an provision of the Certificate of
     Incorporation or by-laws of the Issuer in any manner that would adversely
     affect in any way the powers, preferences or relative participating,
     optional or other special rights of the Common Stock or which would
     adversely affect the rights of the Holders of the Warrants,

          (iii) take all such action as may be reasonably necessary in order
     that the Issuer may validly and legally issue fully paid and nonassessable
     shares of Common Stock, free and clear of any liens, claims, encumbrances
     and restrictions (other than as provided herein) upon the exercise of this
     Warrant, and

          (iv) use its best efforts to obtain all such authorizations,
     exemptions or consents from any public regulatory body having jurisdiction
     thereof as may be reasonably necessary to enable the Issuer to perform its
     obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

<PAGE>


     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

     (i) In case the Issuer after the Original Issue Date shall do any of the
following (each, a "Triggering Event"):

               (a) consolidate with or merge into any other Person and the
          Issuer shall not be the continuing or surviving corporation of such
          consolidation or merger, or

               (b) permit any other Person to consolidate with or merge into the
          Issuer and the Issuer shall be the continuing or surviving Person but,
          in connection with such consolidation or merger, any Capital Stock of
          the Issuer shall be changed into or exchanged for Securities of any
          other Person or cash or any other property, or

               (c) transfer all or substantially all of its properties or assets
          to any other Person, or

               (d) effect a capital reorganization or reclassification of its
          Capital Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such
Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the



<PAGE>


adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

     (ii) Notwithstanding anything contained in this Warrant to the contrary,
the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than the Issuer) which may be required
to deliver any Securities, cash or property upon the exercise of this Warrant as
provided herein shall assume, by written instrument delivered to, and reasonably
satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer
under this Warrant (and if the Issuer shall survive the consummation of such
Triggering Event, such assumption shall be in addition to, and shall not release
the Issuer from, and continuing obligations of the Issuer under this Warrant)
and (B) the obligation to deliver to such Holder such shares of Securities, cash
or property as, in accordance with the foregoing provisions of this subsection
(a), such Holder shall be entitled to receive, and such Person shall have
similarly delivered to such Holder an opinion of counsel for such Person, which
counsel shall be reasonably satisfactory to such holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of the subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to delivery upon any exercise of this Warrant or the exercise of any
rights pursuant hereto.

     (iii) If with respect to any Triggering Event, the Holder of this Warrant
has exercised its right as provided in clause (y) of subparagraph (i) of this
subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees that
as a condition to the consummation of any such Triggering Event the Issuer shall
secure such right of Holder to sell this Warrant to the Person continuing after
or surviving such Triggering Event and the Issuer shall not effect any such
Triggering Event unless upon or prior to the consummation thereof the amounts of
cash, property and/or Securities required under such clause (y) are delivered to
the Holder of this Warrant. The obligation of the Issuer to secure such right of
the Holder to sell this Warrant shall be subject to such Holder's cooperation
with the Issuer, including, without limitation, the giving of customary
representations and warranties to the purchaser in connection with any such
sale. Prior notice of any Triggering Event shall be given to the Holder of this
Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a  combination  of shares,



<PAGE>


the Warrant Price shall be proportionately increased (as at the effective date
of such combination or, if the Issuer shall take a record of Holders of its
Common Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately
after such purchase, redemption or acquisition. For the purposes of this



<PAGE>


subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.




<PAGE>

          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>


     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

     10. Governing Law. THIS WARRANT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, WITHOUT GIVING EFFECT TO

of this Warrant in the event of any default or threatened default by the Issuer
in the performance of or compliance with any of the terms of this Warrant are
not and will not be adequate and that, to the fullest extent permitted by law,
such terms may be specifically enforced by a decree for the specific performance
of any agreement contained herein or by an injunction against a violation of any
of the terms hereof or otherwise.

     13. Successors and Assigns. This Warrant and the rights evidenced hereby
shall inure to the benefit of and be binding upon the successors and assigns of
the Issuer, the Holder hereof and (to the extent provided herein) the Holders of
Warrant Stock issued pursuant hereto, and shall be enforceable by any such
Holder or Holder of Warrant Stock.

     14. Modification and Severability. If, in any action before any court or
agency legally empowered to enforce any provision contained herein, any
provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     15. Headings. The headings of the Sections of this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

     IN WITNESS WHEREOF, the Issuer has executed this Warrant as of the day and

of Warrant Stock as the Holder hereof shall designate at the time of such
exchange. All Warrants issued on transfers or exchanges shall be dated the
Original Issue Date and shall be identical with this Warrant except as to the

     that this Warrant or the shares of Warrant Stock to be issued upon exercise
     hereof are being acquired solely for the Holder's own account and not as a
     nominee for any other party, and for investment, and that the Holder will
     not offer, sell or otherwise dispose of this Warrant or any shares of
     Warrant Stock to be issued upon exercise hereof except pursuant to an
     effective registration statement, or an exemption from registration, under
     the Securities Act and any applicable state securities laws.

          (ii) Except as provided in paragraph (iii) below, this Warrant and all
     certificates representing share of Warrant Stock issued upon exercise

     following form:

               THIS WARRANT AND THE SHARE OF COMMON STOCK ISSUABLE UPON EXERCISE
               HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933,

               REGISTERED UNDER THE SECURITIES ACT AND UNDER APPLICABLE STATE
               SECURITIES LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF
               ITS COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
               SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
               SECURITIES LAWS IS NOT REQUIRED.

<PAGE>


          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants.

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through the Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at
all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any


<PAGE>


federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

               (i) not permit the par value, if any, of its Common Stock to
          exceed the then effective Warrant Price,

               (ii) no amend or modify an provision of the Certificate of
          Incorporation or by-laws of the Issuer in any manner that would
          adversely affect in any way the powers, preferences or relative
          participating, optional or other special rights of the Common Stock or
          which would adversely affect the rights of the Holders of the
          Warrants,

               (iii) take all such action as may be reasonably necessary in
          order that the Issuer may validly and legally issue fully paid and
          nonassessable shares of Common Stock, free and clear of any liens,
          claims, encumbrances and restrictions (other than as provided herein)
          upon the exercise of this Warrant, and

               (iv) use its best efforts to obtain all such authorizations,
          exemptions or consents from any public regulatory body having
          jurisdiction thereof as may be reasonably necessary to enable the
          Issuer to perform its obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such



<PAGE>


Warrant, the Issuer will make and deliver, in lieu of such lost, stolen,
destroyed or mutilated Warrant, a new Warrant of like tenor and representing the
right to purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

         4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to  adjustment  from time to time upon the  happening  of
certain events as follows:

     (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

     (i) In case the Issuer after the Original Issue Date shall do any of the
following (each, a "Triggering Event"):

               (a) consolidate with or merge into any other Person and the
          Issuer shall not be the continuing or surviving corporation of such
          consolidation or merger, or

               (b) permit any other Person to consolidate with or merge into the
          Issuer and the Issuer shall be the continuing or surviving Person but,
          in connection with such consolidation or merger, any Capital Stock of
          the Issuer shall be changed into or exchanged for Securities of any
          other Person or cash or any other property, or

               (c) transfer all or substantially all of its properties or assets
          to any other Person, or

               (d) effect a capital reorganization or reclassification of its
          Capital Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such
Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the



<PAGE>


adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

          (ii) Notwithstanding anything contained in this Warrant to the
     contrary, the Issuer will not effect any Triggering Event unless, prior to
     the consummation thereof, each Person (other than the Issuer) which may be
     required to deliver any Securities, cash or property upon the exercise of
     this Warrant as provided herein shall assume, by written instrument
     delivered to, and reasonably satisfactory to, the Holder of this Warrant,
     (A) the obligations of the Issuer under this Warrant (and if the Issuer
     shall survive the consummation of such Triggering Event, such assumption
     shall be in addition to, and shall not release the Issuer from, and
     continuing obligations of the Issuer under this Warrant) and (B) the
     obligation to deliver to such Holder such shares of Securities, cash or
     property as, in accordance with the foregoing provisions of this subsection
     (a), such Holder shall be entitled to receive, and such Person shall have
     similarly delivered to such Holder an opinion of counsel for such Person,
     which counsel shall be reasonably satisfactory to such holder, stating that
     this Warrant shall thereafter continue in full force and effect and the
     terms hereof (including, without limitation, all of the provisions of the
     subsection (a)) shall be applicable to the Securities, cash or property
     which such Person may be required to delivery upon any exercise of this
     Warrant or the exercise of any rights pursuant hereto.

          (iii) If with respect to any Triggering Event, the Holder of this
     Warrant has exercised its right as provided in clause (y) of subparagraph
     (i) of this subsection (a) to sell this Warrant or a portion thereof, the
     Issuer agrees that as a condition to the consummation of any such
     Triggering Event the Issuer shall secure such right of Holder to sell this
     Warrant to the Person continuing after or surviving such Triggering Event
     and the Issuer shall not effect any such Triggering Event unless upon or
     prior to the consummation thereof the amounts of cash, property and/or
     Securities required under such clause (y) are delivered to the Holder of
     this Warrant. The obligation of the Issuer to secure such right of the
     Holder to sell this Warrant shall be subject to such Holder's cooperation
     with the Issuer, including, without limitation, the giving of customary
     representations and warranties to the purchaser in connection with any such
     sale. Prior notice of any Triggering Event shall be given to the Holder of
     this Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a  combination  of shares,



<PAGE>


the Warrant Price shall be proportionately increased (as at the effective date
of such combination or, if the Issuer shall take a record of Holders of its
Common Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately




<PAGE>


after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.




<PAGE>

          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>


     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,

of this Warrant in the event of any default or threatened default by the Issuer

of any agreement contained herein or by an injunction against a violation of any
of the terms hereof or otherwise.

shall inure to the benefit of and be binding upon the successors and assigns of
the Issuer, the Holder hereof and (to the extent provided herein) the Holders of
Warrant Stock issued pursuant hereto, and shall be enforceable by any such
Holder or Holder of Warrant Stock.

     14. Modification and Severability. If, in any action before any court or
agency legally empowered to enforce any provision contained herein, any
provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     15. Headings. The headings of the Sections of this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

     IN WITNESS WHEREOF, the Issuer has executed this Warrant as of the day and

                    TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS REGISTERED UNDER
                    THE SECURITIES ACT AND UNDER APPLICABLE STATE SECURITIES
                    LAWS OR THE ISSUER SHALL HAVE RECEIVED AN OPINION OF ITS
                    COUNSEL THAT REGISTRATION OF SUCH SECURITIES UNDER THE
                    SECURITIES ACT AND UNDER THE PROVISIONS OF APPLICABLE STATE
                    SECURITIES LAWS IS NOT REQUIRED.

<PAGE>

          (iii) The restrictions imposed by this subsection (e) upon the
     transfer of this Warrant and the shares of Warrant Stock to be purchased
     upon exercise hereof shall terminate (A) when such securities shall have
     been effectively registered under the Securities Act, (B) upon the Issuer's
     receipt of an opinion of counsel, in form and substance reasonable
     satisfactory to the Issuer, addressed to the Issuer to the effect that such
     restrictions are no longer required to ensure compliance with the
     Securities Act and state securities laws or (C) upon the Issuer's receipt
     of other evidence reasonably satisfactory to the Issuer that such
     registration and qualification under state securities laws is not required/
     Whenever such restrictions shall cease and terminate as to any such
     securities, the Holder thereof shall be entitled to receive from the Issuer
     (or its transfer agent and registrar), without expense (other than
     applicable transfer taxes, if any), new Warrants (or, in the case of shares
     of Warrant Stock, new certificates) of like tenor not not bearing the
     applicable legend required by paragraph (ii) above relating to the
     Securities Act and state securities laws.

     (f) Continuing Rights of Holder. The Issuer will, at the time of or at any
time after each exercise of this Warrant, upon the request of the Holder hereof,
acknowledge in writing the extent, if any, of its continuing obligation to
afford to such Holder all rights to which such Holder shall continue to be
entitled after such exercise in accordance with the terms of this Warrant,
provided that if any such holder shall fail to make any such request, the
failure shall not affect the continuing obligations of the Issuer to afford such
rights to such Holder.

     3. Stock Fully Paid:Reservation and Listing of Shares:Covenants.

     (a) Stock Full Paid. The Issuer represents, warrants, covenants and agrees
that all shares of Warrant Stock which may be issued upon the exercise of this
Warrant or otherwise hereunder will, upon issuance, be duly authorized, validly
issued, fully paid and non-assessable and free from all taxes, liens and charges
created by or through the Issuer. The Issuer further covenants and agrees that
during the period within which this Warrant may be exercised, the Issuer will at
all times have authorized and reserved for the purpose of the issue upon
exercise of this Warrant a sufficient number of shares of Common Stock to
provide for the exercise of this Warrant.

     (b) Reservation. If any shares of Common Stock required to be reserved for
issuance upon exercise of this Warrant or as otherwise provided hereunder
require registration or qualification with any governmental authority under any



<PAGE>


federal or state law before such shares may be so issued, the Issuer will in
good faith use its best efforts as expeditiously as possible at its expense to
cause such shares to be duly registered or qualified. If the Issuer shall list
any shares of Common Stock on any securities exchange or market it will, at its
expense, list thereon, maintain and increase when necessary such listing, of,
all shares of Warrant Stock from time to time issued upon exercise of this
Warrant or as otherwise provided hereunder, and, to the extent permissible under
the applicable securities exchange rules, all unissued shares of Warrant Stock
which are at any time issuable hereunder, so long as any shares of Common Stock
shall be so listed. The Issuer will also so list on each securities exchange or
market, and will maintain such listing of, any other securities which the Holder
of this Warrant shall be entitled to receive upon the exercise of this Warrant
if at the time any securities of the same class shall be listed on such
securities exchange or market by the Issuer.

     (c) Covenants. The Issuer shall not by any action including, without
limitation, amending the Certificate of Incorporation or the by-laws of the
Issuer, or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities or any other action, avoid or
seek to avoid the observance or performance of any of the terms of this Warrant,
but will at all times in good faith assist in the carrying out of all such terms
and in the taking of all such actions as may be necessary or appropriate to
protect the rights of the Holder hereof against dilution (to the extent
specifically provided herein) or impairment. Without limiting the generality of
the foregoing, the Issuer will:

               (i) not permit the par value, if any, of its Common Stock to
          exceed the then effective Warrant Price,

               (ii) no amend or modify an provision of the Certificate of
          Incorporation or by-laws of the Issuer in any manner that would
          adversely affect in any way the powers, preferences or relative
          participating, optional or other special rights of the Common Stock or
          which would adversely affect the rights of the Holders of the
          Warrants,

               (iii) take all such action as may be reasonably necessary in
          order that the Issuer may validly and legally issue fully paid and
          nonassessable shares of Common Stock, free and clear of any liens,
          claims, encumbrances and restrictions (other than as provided herein)
          upon the exercise of this Warrant, and

               (iv) use its best efforts to obtain all such authorizations,
          exemptions or consents from any public regulatory body having
          jurisdiction thereof as may be reasonably necessary to enable the
          Issuer to perform its obligations under this Warrant.

     (d) Loss, Theft, Destruction of Warrants. Upon receipt of evidence
satisfactory to the Issuer of the ownership of and the loss, theft, destruction
or mutilation of any Warrant and, in the case of any such loss, theft or
destruction, upon receipt of indemnity or security satisfactory to the Issuer,
or, in the case of any such mutilation, upon surrender and cancellation of such
Warrant, the



<PAGE>


Issuer will make and deliver, in lieu of such lost, stolen, destroyed or
mutilated Warrant, a new Warrant of like tenor and representing the right to
purchase the same number of shares of Common Stock.

     (e) Rights and Obligations under the Registration Rights Agreement. The
shares of Warrant Stock are entitled to the benefits and subject to the terms of
the Registration Rights Agreement dated as of even date herewith between the
Issuer and the Holder listed on the signature pages thereof (as amended from
time to time, the "Registration Rights Agreement"). The Issuer shall keep or
cause to be kept a copy of the Registration Rights Agreement, and any amendments
thereto, at its chief executive office and shall furnish, without charge, copies
thereof to the Holder upon request.

     4. Adjustment of Warrant Price and Warrant Share Number. The number and
kind of Securities purchasable upon the exercise of this Warrant and the Warrant
Price shall be subject to adjustment from time to time upon the happening of
certain events as follows:

     (a) Recapitalization, Reorganization, Reclassification, Consolidation,
Merger or Sale.

     (i) In case the Issuer after the Original Issue Date shall do any of the
following (each, a "Triggering Event"):

               (a) consolidate with or merge into any other Person and the
          Issuer shall not be the continuing or surviving corporation of such
          consolidation or merger, or

               (b) permit any other Person to consolidate with or merge into the
          Issuer and the Issuer shall be the continuing or surviving Person but,
          in connection with such consolidation or merger, any Capital Stock of
          the Issuer shall be changed into or exchanged for Securities of any
          other Person or cash or any other property, or

               (c) transfer all or substantially all of its properties or assets
          to any other Person, or

               (d) effect a capital reorganization or reclassification of its
          Capital Stock,

then, and in the case of each such Triggering Event, proper provision shall be
made so that, upon the basis and the terms and in the manner provided in this
Warrant, the Holder of this Warrant shall be entitled (x) upon the exercise
hereof at any time after the consummation of such Triggering Event, to the
extent this Warrant is not exercised prior to such Triggering Event, or is
redeemed in connection with such Triggering Event, to receive at the Warrant
Price in effect at the time immediately prior to the consummation of such
Triggering Event in lieu of the Common Stock issuable upon such exercise of this
Warrant prior to such Triggering Event, the Securities, cash and property to
which such Holder would have been entitled upon the consummation of such
Triggering Event if such Holder had exercised the rights represented by this
Warrant immediately prior thereto, subject to adjustments and increases
(subsequent to such corporate action) as nearly equivalent as possible to the



<PAGE>


adjustments provided for in Section 4 hereof or (y) to sell this Warrant (or, at
such Holder's election, a portion hereof) concurrently with the Triggering Event
to the Person continuing after or surviving such Triggering Event, or to the
Issuer (if Issuer is the continuing or surviving Person) at a sales price equal
to the amount of cash, property and/or Securities to which a holder of the
number of shares of Common Stock which would otherwise have been delivered upon
the exercise of this Warrant would have been entitled upon the effective date of
closing of any such Triggering Event (the "Event Consideration"), less the
amount or portion of such Event Consideration having a fair value equal to the
aggregate Warrant Price applicable to this Warrant or the portion hereof so
sold.

     (ii) Notwithstanding anything contained in this Warrant to the contrary,
the Issuer will not effect any Triggering Event unless, prior to the
consummation thereof, each Person (other than the Issuer) which may be required
to deliver any Securities, cash or property upon the exercise of this Warrant as
provided herein shall assume, by written instrument delivered to, and reasonably
satisfactory to, the Holder of this Warrant, (A) the obligations of the Issuer
under this Warrant (and if the Issuer shall survive the consummation of such
Triggering Event, such assumption shall be in addition to, and shall not release
the Issuer from, and continuing obligations of the Issuer under this Warrant)
and (B) the obligation to deliver to such Holder such shares of Securities, cash
or property as, in accordance with the foregoing provisions of this subsection
(a), such Holder shall be entitled to receive, and such Person shall have
similarly delivered to such Holder an opinion of counsel for such Person, which
counsel shall be reasonably satisfactory to such holder, stating that this
Warrant shall thereafter continue in full force and effect and the terms hereof
(including, without limitation, all of the provisions of the subsection (a))
shall be applicable to the Securities, cash or property which such Person may be
required to delivery upon any exercise of this Warrant or the exercise of any
rights pursuant hereto.

     (iii) If with respect to any Triggering Event, the Holder of this Warrant
has exercised its right as provided in clause (y) of subparagraph (i) of this
subsection (a) to sell this Warrant or a portion thereof, the Issuer agrees that
as a condition to the consummation of any such Triggering Event the Issuer shall
secure such right of Holder to sell this Warrant to the Person continuing after
or surviving such Triggering Event and the Issuer shall not effect any such
Triggering Event unless upon or prior to the consummation thereof the amounts of
cash, property and/or Securities required under such clause (y) are delivered to
the Holder of this Warrant. The obligation of the Issuer to secure such right of
the Holder to sell this Warrant shall be subject to such Holder's cooperation
with the Issuer, including, without limitation, the giving of customary
representations and warranties to the purchaser in connection with any such
sale. Prior notice of any Triggering Event shall be given to the Holder of this
Warrant in accordance with Section 12 hereof.

     (b) Subdivision or Combination of Shares. If the Issuer, at any time while
this Warrant is outstanding, shall subdivide or combine any shares of Common
Stock, (i) in case of subdivision of shares, the Warrant Price shall be
proportionately reduced (as at the effective date of such subdivision or, if the
Issuer shall take a record of Holders of its Common Stock for the purpose of so
subdividing, as at the applicable record date, whichever is earlier) to reflect
the increase in the total number of shares of Common Stock outstanding as a
result of such subdivision, or (ii) in the case of a  combination  of shares,



<PAGE>


the Warrant Price shall be proportionately increased (as at the effective date
of such combination or, if the Issuer shall take a record of Holders of its
Common Stock for the purpose of so combining, as at the applicable record date,
whichever is earlier) to reflect the reduction in the total number of shares of
Common Stock outstanding as a result of such combination.

     (c) Certain Dividends and Distributions. If the Issuer, at any time while
this Warrant is outstanding, shall:

          (i) Stock Dividends. Pay a dividend in, or make any other distribution
     to its stockholders (without consideration therefor) or, shares of Common
     Stock, the Warrant Price shall be adjusted, as at the date the Issuer shall
     take a record of the Holders of the Issuer's Capital Stock for the purpose
     of receiving such dividend or other distribution (or if no such record is
     taken, as at the date of such payment or other distribution), to that price
     determined by multiplying the Warrant Price in effect immediately prior to
     such record date (or if no such record is taken, then immediately prior to
     such payment of other distribution), by a fraction (1) the numerator of
     which shall be the total number of shares of Common Stock outstanding
     immediately prior to such dividend or distribution, and (2) the denominator
     of which shall be the total number of shares of Common Stock outstanding
     immediately after such dividend or distribution (plus in the event that the
     Issuer paid cash for fractional shares, the number of additional shares
     which would have been outstanding had the Issuer issued fractional shares
     in connection with said dividends); or

          (ii) Other Dividends. Pay a dividend on, or make any distribution of
     its assets upon or with respect to (including, but not limited to, a
     distribution of its property as a dividend in liquidation or partial
     liquidation or by way of return of capital), the Common Stock (other than
     as described in clause (i) of this subsection (c)), or in the event that
     the Company shall offer options or rights to subscribe for shares of Common
     Stock, or issue any Common Stock Equivalents, to all of its holders of
     Common Stock, then on the record date for such payment, distribution or
     offer, or, in the absence of a record date, on the date of such payment,
     distribution or offer, the Holder shall receive what the Holder would have
     received had it exercised this Warrant in full immediately prior to the
     record date of such payment, distribution or offer or, in the absence of a
     record date, immediately prior to the date of such payment, distribution or
     offer.

     (d) Purchase of Common Stock by the Issuer. If the Issuer at any time while
this Warrant is outstanding shall, directly or indirectly through a Subsidiary
or otherwise, purchase, redeem or otherwise acquire any shares of Common Stock
at a price per share greater than the Per Share Market Value then in effect,
then the Warrant Price upon each such purchase, redemption or acquisition shall
be adjusted to that price determined by multiplying such Warrant Price by a
fraction (i) the numerator of which shall be the number of shares of Common
Stock outstanding immediately prior to such purchase, redemption or acquisition
minus the number of shares of Common Stock which the aggregate consideration for
the total number of such shares of Common Stock so purchased, redeemed or
acquired would purchase at the Per Share Market Value; and (ii) the denominator
of which shall be the number of shares of Common Stock outstanding immediately




<PAGE>


after such purchase, redemption or acquisition. For the purposes of this
subsection (f), the date as of which the Per Share Market Value shall be
computed shall be the earlier of (x) the date on which the Issuer shall enter
into a firm contract for the purchase, redemption or acquisition of such Common
Stock, or (y) the date of actual purchase, redemption or acquisition of such
Common Stock. For the purposes of this subsection (f), a purchase, redemption or
acquisition of a Common Stock Equivalent shall be deemed to be a purchase of the
underlying Common Stock, and the computation herein required shall be made on
the basis of the full exercise, conversion or exchange of such Common Stock
Equivalent on the date as of which such computation is required hereby to be
made, whether or not such Common Stock Equivalent is actually exercisable,
convertible or exchangeable on such date.

     (e) Other Provisions Applicable to Adjustments Under this Section 4. The
following provisions shall be applicable to the making of adjustments in the
Warrant Price hereinbefore provided in Section 4:

          (i) Computation of Consideration. The consideration received by the
     Issuer shall be deemed to be the following: to the extent that any
     Additional Shares of Common Stock or any Common Stock Equivalents shall be
     issued for a cash consideration, the consideration received by the Issuer
     therefor, or if such Additional Shares of Common Stock or Common Stock
     Equivalents are offered by the Issuer for subscription, the subscription
     price, or, if such Additional Shares of Common Stock or Common Stock
     Equivalents are sold to underwriters or dealers for public offering without
     a subscription offering, the public offering price, in any such case
     excluding any amounts paid or receivable for accrued interest or accrued
     dividends and without deduction of any compensation, discounts,
     commissions, or expenses paid or incurred by the Issuer for or in
     connection with the underwriting thereof or otherwise in connection with
     the issued thereof; to the extent that such issuance shall be for a
     consideration other than cash, then, except as herein otherwise expressly
     provided, the fair market value of such consideration at the time of such
     issuance as determined in good faith by the Board. The consideration for
     any Additional Shares of common Stock issuable pursuant to any Common Stock
     Equivalents shall be the consideration received by the Issuer for issuing
     such Common Stock Equivalents, plus the additional consideration payable to
     the Issuer upon the exercise, conversion or exchange of such Common Stock
     Equivalents. In case of the issuance at any time of any Additional Shares
     of Common Stock or Common Stock Equivalents in payment or satisfaction of
     any dividend upon any class of Capital Stock of the Issuer other than
     Common Stock, the Issuer shall be deemed to have received for such
     Additional Shares of Common Stock or Common Stock Equivalents a
     consideration equal to the amount of such dividend so paid or satisfied. In
     any case in which the consideration to be received or paid shall be other
     than cash, the Board shall notify the Holder of this Warrant of its
     determination of the fair market value of such consideration prior to
     payment or accepting receipt thereof. If, within thirty days after receipt
     of said notice, the Majority Holders shall notify the Board in writing of
     their objection to such determination, a determination of the fair market
     value of such consideration shall be made by an Independent Appraiser
     selected by the Majority Holders with the approval of the Board (which
     approval shall not be unreasonable withheld), whose fees and expenses shall
     be paid by the Issuer.




<PAGE>

          (ii) Readjustment of Warrant Price. Upon the expiration or termination
     of the right to convert, exchange or exercise any Common Stock Equivalent
     the issuance of which effected an adjustment in the Warrant Price, if such
     Common Stock Equivalent shall not have been converted, exercised or
     exchanged in its entirety, the number of shares of Common Stock deemed to
     be issued and outstanding by reason of the fact that they were issuable
     upon conversion, exchange or exercise of any such Common Stock Equivalent
     shall no longer be computed as set forth above, and the Warrant Price shall
     forthwith be readjusted and thereafter be the price which it would have
     been (but reflecting any other adjustments in the Warrant Price made
     pursuant to the provisions of this Section 4 after the issuance of such
     Common Stock Equivalent) had the adjustment of the Warrant Price been made
     in accordance with the issuance or sale of the number of Additional Shares
     of Common Stock actually issued upon conversion, exchange or issuance of
     such Common Stock Equivalent and thereupon only the number of Additional
     Shares of Common Stock actually so issued shall be deemed to have been
     issued and only the consideration actually received by the Issuer (computed
     as in clause (i) of this subsection (g) shall be deemed to have been
     received by the Issuer.

          (iii) Outstanding Common Stock. The number of shares of common Stock
     at any time outstanding shall (A) not include any shares thereof then
     directly or indirectly owned or held by or for the account of the Issuer or
     any of its Subsidiaries, and (B) be deemed to include all shares of Common
     Stock then issuable upon conversion, exercise or exchange of any then
     outstanding Common Stock Equivalents or any other evidences of
     Indebtedness, shares of Capital Stock or other Securities which are or may
     be at any time convertible into or exchangeable for shares of Common Stock
     or Other Common Stock.

     (f) Other Action Affecting Common Stock. In case after the Original Issue
Date the Issuer shall take any action affecting its Common Stock, other than an
action described in any of the foregoing subsections (a) through (g) of this
Section 4, inclusive, and the failure to make any adjustment would not fairly
protect the purchase rights represented by this Warrant in accordance with the
essential intent and principle of this Section 4, then the Warrant Price shall
be adjusted in such manner and at such time as the Board may in good faith
determine to be equitable in the circumstances.

     (g) Adjustment of Warrant Share Number. Upon each adjustment in the Warrant
Price pursuant to any of the foregoing provisions of this Section 4, the Warrant
Share Number shall be adjusted, to the nearest one hundredth of a whole share,
to the product obtained by multiplying the Warrant Share Number immediately
prior to such adjustment in the Warrant Price by a fraction, the numerator of
which shall be the Warrant Price immediately before giving effect to such
adjustment and the denominator of which shall be the Warrant Price immediately
after giving effect to such adjustment. If the Issuer shall be in default under
any provision contained in Section 3 of this Warrant so that shares issued at
the Warrant Price adjusted in accordance with this Section 4 would not be
validly issued, the adjustment of the Warrant Share Number provided for in the
foregoing sentence shall nonetheless be made and the Holder of this Warrant
shall be entitled to purchase such greater number of shares at the lowest price
at which such shares may then be validly issued under applicable law. Such
exercise shall not constitute a waiver of any claim arising against the Issuer
by reason of its default under Section 3 of this Warrant.

<PAGE>

     (h) Form of Warrant after Adjustments. The form of this Warrant need not be
changed because of any adjustments in the Warrant Price or the number and kind
of Securities purchasable upon the exercise of this Warrant.

     5. Notice of Adjustments. Whenever the Warrant Price or Warrant Share
Number shall be adjusted pursuant to Section 4 hereof (for purposes of this
Section 5, each an "adjustment"), the Issuer shall cause its Chief Financial
Officer to prepare and execute a certificate setting forth, in reasonable
detail, the event requiring the adjustment, the amount of the adjustment, the
method by which such adjustment was calculated (including a description of the
basis on which the Board made any determination hereunder), and the Warrant
Price and Warrant Share Number after giving effect to such adjustment, and shall
cause copies of such certificate to be delivered to the Holder of this Warrant
promptly after each adjustment. Any dispute between the Issuer and the Holder of
this Warrant with respect to the matters set forth in such certificate may at
the option of the Holder of this Warrant be submitted to one of the national
accounting firms currently known as the "big five" selected by the Holder,
provided that the Issuer shall have ten days after receipt of notice from such
Holder of its selection of such firm to object thereto, in which case such
Holder shall select another such firm and the Issuer shall have no such right of
objection. The firm selected by the Holder of this Warrant as provided in the
preceding sentence shall be instructed to deliver a written opinion as to such
matters to the Issuer and such Holder within thirty days after submission to it
of such dispute. Such opinion shall be final and binding on the parties hereto.
The fees and expenses of such accounting firm shall be paid by the Issuer.

     6. Fractional Shares. No fractional shares of Warrant Stock will be issued
in connection with and exercise hereof, but in lieu of such fractional shares,
the Issuer shall make a cash payment therefor equal in amount to the product of
the applicable fraction multiplied by the Per Share Market Value then in effect.

     such date, then the closing bid price on such exchange or quotation system
     on the date nearest preceding such date, or (b) if the Common Stock is not
     then reported by the OTC Bulletin Board or the National Quotation Bureau
     Incorporated (or similar organization or agency succeeding to its functions
     of reporting prices), then the average of the "Ping Sheet" quotes for the
     relevant conversion period, as determined in good faith by the holder, or

     of a share of Common Stock as determined by an Independent Appraiser
     selected in good faith by the Majority Holders; provided, however, that the
     Issuer, after receipt of the determination by such Independent Appraiser,
     shall have the right to select an additional Independent Appraiser, in
     which case, the fair market value shall be equal to the average of the
     determinations by each such Independent Appraiser; and provided, further

     appropriately adjusted for any stock dividends, stock splits or other
     similar transactions during such period. The Issuer shall pay all costs and
     expenses of each Independent Appraiser. The determination of fair market
     value by an Independent Appraiser shall be based upon the fair market value
     of the Issuer determined on a going concern basis as between a willing
     buyer and a willing seller and taking into account all relevant factors
     determinative of value, and shall be final and binding on all parties. In
     determining the fair market value of any shares of Common Stock, no
     consideration shall be given to any restrictions on transfer of the Common
     Stock imposed by agreement or by federal or state securities laws, or to

of this Warrant in the event of any default or threatened default by the Issuer
in the performance of or compliance with any of the terms of this Warrant are
not and will not be adequate and that, to the fullest extent permitted by law,
such terms may be specifically enforced by a decree for the specific performance
of any agreement contained herein or by an injunction against a violation of any
of the terms hereof or otherwise.

     13. Successors and Assigns. This Warrant and the rights evidenced hereby
shall inure to the benefit of and be binding upon the successors and assigns of
the Issuer, the Holder hereof and (to the extent provided herein) the Holders of
Warrant Stock issued pursuant hereto, and shall be enforceable by any such
Holder or Holder of Warrant Stock.

     14. Modification and Severability. If, in any action before any court or
agency legally empowered to enforce any provision contained herein, any
provision hereof is found to be unenforceable, then such provision shall be
deemed modified to the extent necessary to make it enforceable by such court or
agency. If any such provision is not enforceable as set forth in the preceding
sentence, the unenforceability of such provision shall not affect the other
provisions of this Warrant, but this Warrant shall be construed as if such
unenforceable provision had never been contained herein.

     15. Headings. The headings of the Sections of this Warrant are for
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

     IN WITNESS WHEREOF, the Issuer has executed this Warrant as of the day and
year first above written.

the Commission a "shelf" Registration Statement covering all Registrable
Securities for an offering to be made on a continuous basis pursuant to Rule
415. The Registration Statement shall be on Form S-3 (except if the Company is
not then eligible to register for resale the Registrable Securities on Form S-3,
in which case such registration shall be on another appropriate form in
accordance herewith). The Company shall (i) not permit any securities other than
the Registrable Securities to be included in the Registration Statement and (ii)
use its best efforts to cause the Registration Statement to be declared
effective under the Securities Act as promptly as possible after the filing
thereof, but in any event prior to the Effectiveness Date, and to keep such
Registration Statement continuously effective under the Securities Act until
such date as is the earlier of (x) the date when all Registrable Securities
covered by such Registration Statement have been sold or (y) the date on which
the Registrable Securities may be sold without any restriction pursuant to Rule
144(k) as determined by the counsel to the Company pursuant to a written opinion
letter, addressed to the Company's transfer agent to such effect (the

Commission that the Commission has no comments with respect to the Registration
Statement (the "Commission Notice"), the Company shall use its best efforts to
cause the Registration Statement to be declared effective no later than five (5)

Registration Statement is required to be filed because the actual number of
shares of Common Stock into which the Warrants are exercisable exceeds the
number of shares of Common Stock initially registered in respect of the
Conversion Shares and the Warrant Shares based upon the computation on the
Closing Date, the Company shall have twenty (20)  Business  Days to file such



<PAGE>

additional Registration Statement, and the Company shall use its best efforts to
cause such additional Registration Statement to be declared effective by the
Commission as soon as possible, but in no event later than forth-five (45) days
after filing.

     3. Registration Procedures.

          In connection with the Company's registration obligations hereunder,
the Company shall:

          (a) Prepare and file with the Commission on or prior to the Filing
Date, a Registration Statement on Form S-3 (or if the Company is not then
eligible to register for resale the Registrable Securities on Form S-3 such
registration shall be on another appropriate form in accordance herewith) in
accordance with the method or methods of distribution thereof as specified by
the Holders (except if otherwise directed by the Holders), and cause the
Registration Statement to become effective and remain effective as provided
herein; provided, however, that not less than five (5) Business Days prior to
the filing of the Registration Statement or any related Prospectus or any
amendment or supplement thereto (including any document that would be
incorporated therein by reference), the Company shall (i) furnish to the Holders
and any Special Counsel, copies of all such documents proposed to be filed,
which documents (other than those incorporated by reference) will be subject to
the review of such Holders and such Special Counsel, and (ii) at the request of
any Holder cause its officers and directors, counsel and independent certified
public accountants to respond to such inquiries as shall be necessary, in the
reasonable opinion of counsel to such Holders, to conduct a reasonable
investigation within the meaning of the Securities Act. The Company shall not
file the Registration Statement or any such Prospectus or any amendments or
supplements thereto to which the Holders of a majority of the Registrable
Securities or any Special Counsel shall reasonably object in writing within
three (3) Business Days of their receipt thereof.

          (b) (i) Prepare and file with the Commission such amendments,
including post- effective amendments, to the Registration Statement as may be
necessary to keep the Registration Statement continuously effective as to the
applicable Registrable Securities for the Effectiveness Period and prepare and
file with the Commission such additional Registration Statements in order to
register for resale under the Securities Act all of the Registrable Securities;
(ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement, and as so supplemented or amended to be filed pursuant to
Rule 424 (or any similar provisions then in force) promulgated under the
Securities Act; (iii) respond as promptly as possible to any comments received
from the Commission with respect to the Registration Statement or any amendment
thereto and as promptly as possible provide the Holders true and complete copies
of all correspondence from and to the Commission relating to the Registration
Statement; and (iv) comply in all material respects with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
Registrable Securities covered by the Registration Statement during the
applicable period in accordance with the intended methods of disposition by the
Holders thereof set forth in the Registration Statement as so amended or in such
Prospectus as so supplemented.

<PAGE>


          (c) Notify the Holders of Registrable Securities to be sold and any
Special Counsel as promptly as possible (and, in the case of (i)(A) below, not
less than five (5) Business Days prior to such filing) and (if requested by any
such Person) confirm such notice in writing no later than one (1) Business Day
following the day (i)(A) when a Prospectus or any Prospectus supplement or
post-effective amendment to the Registration Statement is proposed to be filed;
(B) when the Commission notifies the Company whether there will be a "review" of
such Registration Statement and whenever the Commission comments in writing on
such Registration Statement and (C) with respect to the Registration Statement
or any post-effective amendment, when the same has become effective; (ii) of any
request by the Commission or any other Federal or state governmental authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional information; (iii) of the issuance by the Commission of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable Securities or the initiation of any Proceedings for that
purpose; (iv) if at any time any of the representations and warranties of the
Company contained in any agreement contemplated hereby ceases to be true and
correct in all material respects; (v) of the receipt by the Company of any
notification with respect to the suspension of the qualification or exemption
from qualification of any of the Registrable Securities for sale in any
jurisdiction, or the initiation or threatening of any Proceeding for such
purpose; and (vi) of the occurrence of any event that makes any statement made
in the Registration Statement or Prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires any revisions to the Registration Statement, Prospectus or other
documents so that, in the case of the Registration Statement or the Prospectus,
as the case may be, it will not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein, in the light of the circumstances under which they
were made, not misleading.

          (d) Use its best efforts to avoid the issuance of, or if issued,
obtain the withdrawal of, (i) any order suspending the effectiveness of the
Registration Statement or (ii) any suspension of the qualification (or exemption
from qualification) of any of the Registrable Securities for sale in any
jurisdiction, at the earliest practicable moment.

          (e) If requested by the Holders of a majority in interest of the
Registrable Securities, (i) promptly incorporate in a Prospectus supplement or
post-effective amendment to the Registration Statement such information as the
Company reasonably agrees should be included therein and (ii) make all required
filings of such Prospectus supplement or such post-effective amendment as soon
as practicable after the Company has received notification of the matters to be
incorporated in such Prospectus supplement or post-effective amendment.

          (f) Furnish to each Holder and any Special Counsel, without charge, at
least one conformed copy of each Registration Statement and each amendment
thereto, including financial statements and schedules, all documents
incorporated or deemed to be incorporated therein by reference, and all exhibits
to the extent requested by such Person (including those previously furnished or
incorporated by reference) promptly after the filing of such documents with the
Commission.

<PAGE>

          (g) Promptly deliver to each Holder and any Special Counsel, without
charge, as many copies of the Prospectus or Prospectuses (including each form of
prospectus) and each amendment or supplement thereto as such Persons may
reasonably request; and the Company hereby consents to the use of such
Prospectus and each amendment or supplement thereto by each of the selling
Holders in connection with the offering and sale of the Registrable Securities
covered by such Prospectus and any amendment or supplement thereto.

          (h) Prior to any public offering of Registrable Securities, use its
best efforts to register or qualify or cooperate with the selling Holders and
any Special Counsel in connection with the registration or qualification (or
exemption from such registration or qualification) of such Registrable
Securities for offer and sale under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder requests in writing, to
keep each such registration or qualification (or exemption therefrom) effective
during the Effectiveness Period and to do any and all other acts or things
necessary or advisable to enable the disposition in such jurisdictions of the
Registrable Securities covered by a Registration Statement; provided, however,
that the Company shall not be required to qualify generally to do business in
any jurisdiction where it is not then so qualified or to take any action that
would subject it to general service of process in any such jurisdiction where it
is not then so subject or subject the Company to any material tax in any such
jurisdiction where it is not then so subject.

          (i) Cooperate with the Holders to facilitate the timely preparation
and delivery of certificates representing Registrable Securities to be sold
pursuant to a Registration Statement, which certificates shall be free of all
restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any Holder may request at least
two (2) Business Days prior to any sale of Registrable Securities.

          (j) Upon the occurrence of any event contemplated by Section 3(c)(vi),
as promptly as possible, prepare a supplement or amendment, including a
post-effective amendment, to the Registration Statement or a supplement to the
related Prospectus or any document incorporated or deemed to be incorporated
therein by reference, and file any other required document so that, as
thereafter delivered, neither the Registration Statement nor such Prospectus
will contain an untrue statement of a material fact or omit to state a material
fact required to be stated therein or necessary to make the statements therein,
in the light of the circumstances under which they were made, not misleading.

          (k) Use its best efforts to cause all Registrable Securities relating
to such Registration Statement to be listed on the Nasdaq Small Cap Market and
any other securities exchange, quotation system, market or over-the-counter
bulletin board, if any, on which similar securities issued by the Company are
then listed as and when required pursuant to the Purchase Agreement.

          (l) Comply in all material respects with all applicable rules and
regulations of the Commission and make generally available to its security
holders earning statements satisfying the provisions os Section 11(a) of the
Securities Act and Rule 158 not later than 45 days after the end of any 12-month
period (or 90 days after the end of any 12-month period if such period is a




<PAGE>


fiscal year) commencing on the first day of the first fiscal quarter of the
Company after the effective date of the Registration Statement, which statement
shall conform to the requirements of Rule 158.

          (m) The Company may require each selling Holder to furnish to the
Company information regarding such Holder and the distribution of such
Registrable Securities as is required by law to be disclosed in the Registration
Statement, and the Company may exclude from such registration the Registrable
Securities of any such Holder who unreasonably fails to furnish such information
within a reasonable time after receiving such request.

          If the Registration Statement refers to any Holder by name or
otherwise as the holder of any securities of the Company, then such Holder shall
have the right to require (if such reference to such Holder by name or otherwise
is not required by the Securities Act or any similar federal statute then in
force) the deletion of the reference to such Holder in any amendment or
supplement to the Registration Statement filed or prepared subsequent to the
time that such reference ceases to be required.

          Each Holder covenants and agrees that (i) it will not sell any
Registrable Securities under the Registration Statement until it has received
copies of the Prospectus as then amended or supplemented as contemplated in
Section 3(g) and notice from the Company that such Registration Statement and
any post-effective amendments thereto have become effective as contemplated by
Section 3(c) and (ii) it and its officers, directors or Affiliates, if any, will
comply with the prospectus delivery requirements of the Securities Act as
applicable to them in connection with sales of Registrable Securities pursuant
to the Registration Statement.

          Each Holder agrees by its acquisition of such Registrable Securities
that, upon receipt of a notice from the Company of the occurrence of any event
of the kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), 3(c)(v) or
3(c)(vi), such Holder will forthwith discontinue disposition of such Registrable
Securities under the Registration Statement until Such Holder's receipt of the
copies of the supplemented Prospectus and/or amended Registration Statement
contemplated by Section 3(j), or until it is advised in writing (the "Advice")
by the Company that the use of the applicable Prospectus may be resumed, and, in
either case, has received copies of any additional or supplemental filings that
are incorporated or deemed to be incorporated by reference in such Prospectus or
Registration Statement.

          (n) If (i) there is material non-public information regarding the
Company which the Company's Board of Directors (the "Board") reasonably
determines not to be in the Company's best interest to disclose and which the
Company is not otherwise required to disclose, or (ii) there is a significant
business opportunity (including, but not limited to, the acquisition or
disposition of assets (other than in the ordinary course of business) or any
merger, consolidation, tender offer or other similar transaction) available to
the Company which the Board reasonably determines not to be in the Company's
best interest to disclose and which the Company would be required to disclose
under the Registration Statement, then the Company may postpone or suspend its
obligation under this Section 3(n) for more than 45 days in the aggregate during
any 12 month period (each, a "Blackout Period"); provided, however, that no such
postponement or suspension shall be permitted for consecutive 20 day periods,
arising out of the same set of facts, circumstances or transactions.

     4. Registration Expenses

          All fees and expenses incident to the performance of or compliance
with this Agreement by the Company shall be borne by the Company whether or not
the Registration Statement is filed or becomes effective and whether or not any
Registrable Securities are sold pursuant to the Registration Statement. The fees
and expenses referred to in the foregoing sentence shall include, without
limitation, (i) all registration and filing fees (including, without limitation,
fees and expenses (A) with respect to filings required to be made with the OTC
Bulletin Board and each other securities exchange or market on which Registrable
Securities are required hereunder to be listed, (B) with respect to filings
required to be made with the Commission, (C) with respect to filings required to
be made under Nasdaq SmallCap Market Rules and (C) in compliance with state
securities or Blue Sky laws (including, without limitation, fees and
disbursements of counsel for the Holders in connection with Blue Sky
qualifications of the Registrable Securities and determination of the
eligibility of the Registrable Securities for investment under the laws of such
jurisdictions as the Holders of a majority of Registrable Securities may
designate)), (ii) printing expenses (including, without limitation, expenses of
printing certificates for Registrable Securities and of printing prospectuses if
the printing of prospectuses is requested by the holders of a majority of the
Registrable Securities included in the Registration Statement), (iii) messenger,
telephone and delivery expenses, (iv) fees and disbursements of counsel for the
Company and Special Counsel for the Holders, in the case of the Special Counsel,
to a maximum amount of $10,000, (v) Securities Act liability insurance, if the
Company so desires such insurance, and (vi) fees and expenses of all other
Persons retained by the Company in connection with the consummation of the
transactions contemplated by this Agreement, including, without limitation, the
Company's independent public accountants (including the expenses of any comfort
letters or costs associated with the delivery by independent public accountants
of a comfort letter or comfort letters). In addition, the Company shall be
responsible for all of its internal expenses incurred in connection with the
consummation of the transactions contemplated by this Agreement (including,
without limitation, all salaries and expenses of its officers and employees
performing legal or accounting duties), the expense of any annual audit, the
fees and expenses incurred in connection with the listing of the Registrable
Securities on any securities exchange as required hereunder.


     5. Indemnification

          (a) Indemnification by the Company. The Company shall, notwithstanding
any termination of this Agreement, indemnify and hold harmless each Holder, the
officers, directors, agents, brokers (including brokers who offer and sell
Registrable Securities as principal as a result of a pledge or any failure to
perform under a margin call of Common Stock), investment advisors and employees
of each of them, each Person who controls any such Holder (within the meaning of
Section 15 of the Securities Act or Section 20 of the Exchange Act) and the
officers, directors, agents and employees of each such controlling Person, to
the fullest extent permitted by applicable law, from and against any and all
losses, claims, damages, liabilities, costs (including, without limitation,



<PAGE>


costs of preparation and attorneys' fees) and expenses (collectively, "Losses"),
as incurred, arising out of or relating to any untrue or alleged untrue
statement of a material fact contained in the Registration Statement, any
Prospectus or any form of prospectus or in any amendment or supplement thereto
or in any preliminary prospectus, or arising out of or relating to any omission
or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any Prospectus or form
of prospectus or supplement thereto, in the light of the circumstances under
which they were made) not misleading, except to the extent, but only to the
extent, that such untrue statements or omissions are based solely upon
information regarding such Holder furnished in writing to the Company by such
Holder expressly for use therein, which information was reasonably relied on by
the Company for use therein or to the extent that such information relates to
such Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus or in any amendment or supplement thereto. The Company shall notify
the Holders promptly of the institution, threat or assertion of any Proceeding
of which the Company is aware in connection with the transactions contemplated
by this Agreement. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of an Indemnified Party and
shall survive the transfer of the Registrable Securities by the Holders.

          (b) Indemnification by Holders. Each Holder shall, severally and not
jointly, indemnify and hold harmless the Company, the directors, officers,
agents and employees, each Person who controls the Company (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors, officers, agents or employees of such controlling Persons, to the
fullest extent permitted by applicable law, from and against all Losses, as
incurred, arising solely out of or based solely upon any untrue statement of a
material fact contained in the Registration Statement, any Prospectus, or any
form of prospectus, or arising solely out of or based solely upon any omission
of a material fact required to be stated therein or necessary to make the
statements therein (in the case of any Prospectus or form of prospectus or
supplement thereto, in the light of the circumstances under which they were
made) not misleading, to the extent, but only to the extent, that such untrue
statement or omission is contained in any information so furnished in writing by
such Holder to the Company specifically for inclusion in the Registration
Statement or such Prospectus and that such information was reasonably relied
upon by the Company for use in the Registration Statement, such Prospectus or
such form of prospectus or to the extent that such information relates to such
Holder or such Holder's proposed method of distribution of Registrable
Securities and was reviewed and expressly approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus. Notwithstanding anything to the contrary contained herein, the
Holder shall be liable under this Section 5(b) for only that amount as does not
exceed the net proceeds to such Holder as a result of the sale of Registrable
Securities pursuant to such Registration Statement.

          (c) Conduct of Indemnification Proceedings. If any Proceeding shall be
brought or asserted against any Person entitled to indemnity hereunder (an
"Indemnified Party"), such Indemnified Party promptly shall notify the Person
from whom indemnity is sought (the "Indemnifying Party") in writing, and the
Indemnifying Party shall assume the defense thereof, including the



<PAGE>


employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all fees and expenses incurred in connection with defense thereof;
provided, that the failure of any Indemnified Party to give such notice shall
not relieve the Indemnifying Party of its obligations or liabilities pursuant to
this Agreement, except (and only) to the extent that it shall be finally
determined by a court of competent jurisdiction (which determination is not
subject to appeal or further review) that such failure shall have proximately
and materially adversely prejudiced the Indemnifying Party.

          An Indemnified Party shall have the right to employ separate counsel
in any such Proceeding and to participate in the defense thereof, but the fees
and expenses of such counsel shall be at the expense of such Indemnified Party
or Parties unless: (1) the Indemnifying Party has agreed in writing to pay such
fees and expenses; or (2) the Indemnifying Party shall have failed promptly to
assume the defense of such Proceeding and to employ counsel reasonably
satisfactory to such Indemnified Party in any such Proceeding; or (3) the named
parties to any such Proceeding (including any impleaded parties) include both
such Indemnified Party and the Indemnifying Party, and such Indemnified Party
shall have been advised by counsel that a conflict of interest is likely to
exist if the same counsel were to represent such Indemnified Party and the
Indemnifying Party (in which case, if such Indemnified Party notifies the
Indemnifying Party in writing that it elects to employ separate counsel at the
expense of the Indemnifying Party, the Indemnifying Party shall not have the
right to assume the defense thereof and such counsel shall be at the expense of
the Indemnifying Party). The Indemnifying Party shall not be liable for any
settlement of any such Proceeding effected without its written consent, which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

          All fees and expenses of the Indemnified Party (including reasonable
fees and expenses to the extent incurred in connection with investigating or
preparing to defend such Proceeding in a manner not inconsistent with this
Section) shall be paid to the Indemnified Party, as incurred, within then (10)
Business Days of written notice thereof to the Indemnifying Party (regardless of
whether it is ultimately determined that an Indemnified Party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

          (d) Contribution. If a claim for indemnification under Section 5(a) or
5(b) is unavailable to an Indemnified Party because of a failure or result of a
governmental authority to enforce such indemnification in accordance with its
terms (by reason of public policy or otherwise), then each Indemnifying Party,
in lieu of indemnifying such Indemnified Party, shall contribute to the amount
paid or payable by such Indemnified Party as a result of such Losses, in such
proportion as is appropriate to reflect the relative fault of the Indemnifying
Party and Indemnified Party in connection with the actions, statements or
omissions that resulted in such Losses as well as any other relevant equitable
considerations. The relative fault of such Indemnifying Party and Indemnified



<PAGE>



Party shall be  determined  by  reference  to, among other  things,  whether any
action in  question,  including  any untrue or  alleged  untrue  statement  of a
material fact or omission or alleged omission of a material fact, has been taken
or made by, or relates to information  supplied by, such Indemnifying  Party, or
Indemnified  Party,  and the  parties'  relative  intent,  knowledge,  access to
information  and  opportunity  to correct or prevent such  action,  statement or
omission.  The amount paid or payable by a party as a result of any Losses shall
be deemed to include,  subject to the limitations set forth in Section 5(c), any
reasonable  attorneys'  or other  reasonable  fees or expenses  incurred by such
party in connection with any Proceeding to the extent such party would have been
indemnified  for such fees or expenses if the  indemnification  provided  for in
this  Section  was  available  to such  party  in  accordance  with  its  terms.
Notwithstanding  anything to the contrary  contained herein, the Holder shall be
liable or required to contribute under this Section 5(c) for only that amount as
does not  exceed  the net  proceeds  to such  Holder  as a result of the sale of
Registrable Securities pursuant to such Registration Statement.

          The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 5(d) were determined by pro rata
allocation or by any other method of allocation that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
No Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation.

          The indemnity and contribution agreements contained in this Section
are in addition to any liability that the Indemnifying Parties may have to the
Indemnified Parties.

     6. Rule 144.

          As long as any Holder owns Common Stock, Warrants or Warrant Shares,
the Company covenants to timely file (or obtain extensions in respect thereof
and file within the applicable grace period) all reports required to be filed by
the Company after the date hereof pursuant to Section 13(a) or 15(d) of the
Exchange Act and to promptly furnish the Holders with true and complete copies
of all such filings. As long as any Holder owns Common Stock, Warrants or
Warrant Shares, if the Company is not required to file reports pursuant to
Section 13(a) or 15(d) of the Exchange Act, it will prepare and furnish to the
Holders and make publicly available in accordance with Rule 144(c) promulgated
under the Securities Act annual and quarterly financial statements, together
with a discussion and analysis of such financial statements in form and
substance substantially similar to those that would otherwise be required to
have been made under the Exchange Act. The Company further covenants that it
will take such further action as any Holder may reasonably request, all to the
extent required from time to time to enable such Person to sell Common Stock and
Warrant Shares without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 promulgated under the
Securities Act, including providing any legal opinions referred to in the
Purchase Agreement. Upon the request of any Holder, the Company shall deliver to
such Holder a written certification of a duly authorized officer as to whether
it has complied with such requirements.

     7. Miscellaneous.

          (a) Remedies. In the event of a breach by the Company or by a Holder,
of any of their obligations under this Agreement, each Holder or the Company, as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific performance of its rights under this Agreement. The Company and each
Holder agree that monetary damages would not provide adequate compensation for
any losses incurred by reason of a breach by it of any of the provisions of this
Agreement and hereby further agrees that, in the event of any action for
specific performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

          (b) No Inconsistent Agreements. Neither the Company nor any of its
subsidiaries has, as of the date hereof entered into and currently in effect,
nor shall the Company or any of its subsidiaries, on or after the date of this
Agreement, enter into any agreement with respect to its securities that is
inconsistent with the rights granted to the Holders in this Agreement or
otherwise conflicts with the provisions hereof. Without limiting the generality
of the foregoing, without the written consent of the Holders of a majority of
the then outstanding Registrable Securities, the Company shall not grant to any
Person the right to request the Company to register any securities of the
Company under the Securities Act unless the right so granted are subject in all
respects to the prior rights in full of the Holders set forth herein, and are
not otherwise in conflict with the provisions of this Agreement, or the
Registration Rights Agreement has been declared effective by the SEC.

          (c) No Piggyback on Registrations. Neither the Company nor any of its
security holders (other than the Holders in such capacity pursuant hereto and
the Persons listed on Schedule 7(c) hereto) may include securities of the
Company in the Registration Statement, and the Company shall not after the date
hereof enter into any agreement providing such right to any of its security
holders, unless the right so granted is subject in all respects to the prior
rights in full of the Holders set forth herein, and is not otherwise in conflict
with the provisions of this Agreement.

          (d) Piggy-Back Registrations. If at any time when there is not an
effective Registration Statement covering (i) the Shares of Common Stock or (ii)
the Warrant Shares, the Company shall determine to prepare and file with the
Commission a registration statement relating to an offering for its own account
or the account of others under the Securities Act of any of its equity
securities, other than on Form S-4 or Form S-8 (each as promulgated under the
Securities Act) or its then equivalents relating to equity securities to be
issued solely in connection with any acquisition of any entity or business or
equity securities issuable in connection with stock option or other employee
benefit plans, the Company shall send to each holder of Registrable Securities
written notice of such determination and, if within thirty (30) days after
receipt of such notice, any such holder shall so request in writing (which
request shall specify the Registrable Securities intended to be disposed of by
the Purchasers), the Company will cause the registration under the Securities
Act of all Registrable Securities which the Company has been so requested to
register by the holder, to the extent requisite to permit the disposition of the
Registrable Securities so to be registered, provided that if at any time after
giving written notice of its intention to register any securities and prior to



<PAGE>


the effective date of the registration statement filed in connection with such
registration, the Company shall determine for any reason not to register or to
delay registration of such securities, the Company may, at its election, give
written notice of such determination to such holder and, thereupon, (i) in the
case of a determination not to register, shall be relieved of its obligation to
register any Registrable Securities in connection with such registration (but
not from its obligation to pay expenses in accordance with Section 4 hereof),
and (ii) in the case of a determination to delay registering, shall be permitted
to delay registering any Registrable Securities being registered pursuant to
this Section 7(d) for the same period as the delay in registering such other
securities. The Company shall include in such registration statement all or any
part of such Registrable Securities such holder requests to be registered;
provided, however, that the Company shall not be required to register any
Registrable Securities pursuant to this Section 7(d) that are eligible for sale
pursuant to Rule 144(k) of the Securities Act. In the case of an underwritten
public offering, if the managing underwriter(s) or underwriter(s) should
reasonably object to the inclusion of the Registrable Securities in such
registration statement, then if the Company after consultation with the managing
underwriter should reasonably determine that the inclusion of such Registrable
Securities, would materially adversely affect the offering contemplated in such
registration statement, and based on such determination recommends inclusion in
such registration statement of fewer or none of the Registrable Securities of
the Holders, then (x) the number of Registrable Securities of the Holders
included in such registration statement shall be reduced pro-rata among such
Holders (based upon the number of Registrable Securities requested to be
included in the registration), if the Company after consultation with the
underwriter(s) recommends the inclusion of fewer Registrable Securities, or (y)
none of the Registrable Securities of the Holders shall be included in such
registration statement, if the Company after consultation with the
underwriter(s) recommends the inclusion of none of such Registrable Securities;
provided, however, that if securities are being offered for the account of other
persons or entities as well as the Company, such reduction shall not represent a
greater fraction of the number of Registrable Securities intended to be offered
by the Holders than the fraction of similar reductions imposed on such other
persons or entities (other than the Company).

          (e) Failure to File Registration Statement and Other Events. The
Company and the Purchasers agree that the Holders will suffer damages if the
Registration Statement is not filed on or prior to the Filing Date and not
declared effective by the Commission on or prior to the Effectiveness Date and
maintained in the manner contemplated herein during the Effectiveness Time or if
certain other events occur. The Company and the Holders further agree that it
would not be feasible to ascertain the extent of such damages with precision.
Accordingly, if (i) the Registration Statement is not filed on or prior to the
Filing Date, (or is not declared effective by the Commission on or prior to the
Effectiveness Date or in the event an additional Registration Statement is filed
because the actual number of shares of Common Stock into which the Warrants are
exercisable exceeds the number of shares of Common Stock initially registered is
not filed and declared effective within the time periods set forth in Section
2(a)), or (ii) the Company fails to file with the Commission a request for
acceleration in accordance with Rule 12dl-2 promulgated under the Exchange Act
within five (5) Business Days of the date that the Company is notified (orally
or in writing, whichever is earlier) by the Commission that a Registration
Statement will not be "reviewed," or not subject to further review, or (iii) the




<PAGE>


Registration Statement is filed with and declared effective by the Commission
but thereafter ceases to be effective as to all Registrable Securities at any
time prior to the expiration of the Effectiveness Period, without being
succeeded immediately by a subsequent Registration Statement filed with and
declared effective by the Commission, and such cessation continues for a period
of thirty days after written notice thereof to the Company, or (iv) trading in
the Common Stock shall be suspended or if the Common Stock is delisted from the
Nasdaq SmallCap Market for any reason for more than three Business Days in the
aggregate, and such suspension or delisting continues for a period of fourteen
days after written notice thereof to the Company, or (v) the Company breaches in
a material respect any covenant or other material term or condition to this
Agreement, Purchase Agreement (other than a representation or warranty contained
therein) or any other agreement, document, certificate or other instrument
delivered in connection with the transactions contemplated hereby and thereby,
and such breach continues for a period of thirty days after written notice
thereof to the Company, or (vii) the Company has breached Section 3(n) of this
Agreement (any such failure or breach being referred to as an ("Event"), the
Company shall pay in cash as liquidated damages for such failure and not as a
penalty to each Holder an amount equal to 2% of such Holder's pro rata share of
the purchase price paid by all Holders for all shares of Common Stock purchased
and then outstanding pursuant to the Purchase Agreement for each thirty (30) day
period until the applicable Event has been cured, which shall be pro rated for
such periods less than thirty (30) days (the "Periodic Amount"). Payments to be
made pursuant to this Section 7(e) shall be due and payable in cash immediately
upon demand. The parties agree that the Periodic Amount represents a reasonable
estimate on the part of the parties, as of the date of this Agreement, of the
amount of damages that may be incurred by the Holders if the Registration
Statement is not filed on or prior to the Filing Date or has not been declared
effective by the Commission on or prior to the Effectiveness Date and maintained
in the manner contemplated herein during the Effectiveness Time or if any other
Event as described herein has occurred.

          (f) Specific Enforcement, Consent to Jurisdiction.

               (i) The Company and the Purchasers acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Registration Rights Agreement or the Purchase Agreement were not performed in
accordance with their specific terms or were otherwise breached. It is
accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent or cure breaches of the provisions of this Registration
Rights Agreement or the Purchase Agreement and to enforce specifically the terms
and provisions hereof or thereof, this being in addition to any other remedy to
which any of them may be entitled by law or equity.

               (ii) Each of the Company and the Purchasers (i) hereby
irrevocably submits to the jurisdiction of the United States District Court
sitting in the Southern District of New York for the purposes of any suit,
action or proceeding arising out of or relating to this Agreement or the
Purchase Agreement and (ii) hereby waives, and agrees not to assert in any such
suit, action or proceeding, any claim that it is not personally subject to the
jurisdiction of such court, that the suit, action or proceeding is improper.
Each of the Company and the Purchasers consents to process being served in any
such suit, action or proceeding by mailing a copy thereof to such party at the
address in effect for notices to it under this Agreement and agrees that such




<PAGE>


service shall constitute good and sufficient service of process and notice
thereof. Nothing in this Section 7(f) shall affect or limit any right to serve
process in any other manner permitted by law.

          (g) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given, unless the same shall be in writing and signed by the Company
and each of the Holders. Notwithstanding the foregoing, a waiver or consent to
depart from the provisions hereof with respect to a matter that relates
exclusively to the rights of Holders and that does not directly or indirectly
affect the rights of other Holders may be given by Holders of at least a
majority of the Registrable Securities to which such waiver or consent relates;
provided, however, that the provisions of this sentence may not be amended,
modified, or supplemented except in accordance with the provisions of the
immediately preceding sentence.

          (h) Notices. Any and all notices or other communications or deliveries
required or permitted to be provided hereunder shall be in writing and shall be
deemed given and effective on the earlier of (i) the date of transmission, if
such notice or communication is delivered via facsimile at the facsimile
telephone number specified for notice prior to 5:00 p.m., eastern standard time,
on a Business Day, (ii) the Business Day after the date of transmission, if such
notice or communication is delivered via facsimile at the facsimile telephone

overnight courier service or (iv) actual receipt by the party to whom such

A attached hereto, or with respect to the Company, addressed to:

                    Re: Pollution Research and Control Corp.
                        ------------------------------------

Ladies and Gentlemen:

          We are counsel to Pollution Research and Control Corp., a California
corporation (the "Company"), and have represented the Company in connection with
(i) that certain Debenture (the "Debenture") issued by the Company in favor of
Britannica Associates Limited (the "Holder") which Debenture is convertible into
shares of the Company's common stock, par value $.01 per share (the "Common
Stock"), and (ii) warrants issued to the Holder to purchase shares of the Common
Stock (the "Warrants"). Pursuant to the Debenture, the Company also has entered
into a Registration Rights Agreement with the Holder (the "Registration Rights
Agreement") pursuant to which the Company agreed, among other things, to
register the Registrable Securities (as defined the Registration Rights
Agreement), including the shares of Common Stock issuable upon exercise of the
Warrants, under the Securities Act of 1933, as amended (the "1933 Act"). In
connection with the Company's obligations under the Registration Rights
Agreement, on _______ __, 1999, the Company filed a Registration Statement on
Form S-3 (File No. 333-____________) (the "Registration Statement") with the
Securities and Exchange Commission (the "SEC") relating to the Registrable
Securities which names each of the Holders as a selling stockholder thereunder.

          In connection with the foregoing, we advise you that a member of the
SEC's staff has advised us by telephone that the SEC has entered an order
declaring the Registration Statement effective under the 1933 Act at [ENTER TIME
OF EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge,
after telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                          Very truly yours,

                                          [COMPANY'S COUNSEL]

                                 PROMISSORY NOTE

                                                            Glendale, California

$75,000.00                                                      January 21, 2000

     FOR VALUE RECEIVED, the undersigned, Dasibi China, Inc., a California
corporation (hereinafter referred to as the "Maker"), with its address at 506
Paula Avenue, Glendale, California 91201, agrees and promises to pay to the
order of Britannica Associates, Ltd. (hereinafter referred to as the "Holder"),
at 3rd Floor, Omar Hodge Building, Wickhams, #362, Rhodestown Tortola, British
Virgin Islands, or such other place as the Holder may designate in writing, in
coin or currenty of the United States of America, which at the time of payment
is legal tender for the payment of public and private debts, the principal sum
of seventy five thousand dollars ($75,000), together with interest thereon at
the ten per cent (10%) per annum, from the date herof until maturity, as
hereinafter provided. The principal balance of this Promissory Note (hereinafter
referred to as the "Note"), together with all interest then accrued and unpaid,
shall be due and payable on the date sixty days from the date hereof.

     This Note, and the payment hereof, is guaranteed by Pollution Research and
Control Corp., 506 Paula Avenue, Glendale, California 91201, owner of record and
beneficially of all of the issued and outstanding shares of common stock, $.01
par value per share, of the Maker.

     The Maker may prepay any part or all of this Note at any time without
penalty. Each payment or pre-payment made by the Maker hereunder shall be
applied first to the payment or rep- payment of accrued and unpaid interest, if
any, due on the unpaid principal balance of this Note and the remainder of each
payment or pre-payment made by the Maker shall be applied to the reduction of
the unpaid principal balance hereof.

     If default is made in the payment of this Note, as and when the same is or
becomes due the Holder may, after notice and failure to cure as hereinafter
provided, without additional notice or demand, declare the entire unpaid
principal balance hereof and accrued and unpaid interst, if any, at once due and
payable.

     Except as otherwise specifically set out herein, the Maker waives demand
and presentment for payment, notice of non-payment, protest, notice of protest,
notice of acceleration of the indebtedness due hereunder, and agrees that the
time of payments hereof may be extended without notice at any time and from
time-to-time, and for periods of time for a term or terms in excess of the
original term without notice or consideration to, or consent from the Maker
without same constituting a waiver of the Holder's rights under this Note.

     If payment is not received by the tenth day after it is due, then the
Holder agrees to give written notice of such to the Maker. If payment is not
received within five days of said notice then the Holder may at his election
accelerate this Note. The Holder may charge a late charge of two per cent (2%)
of the amount of the payment received after the tenth day such payment is due.

<PAGE>


     If the entire outstanding principal balance becomes due, the Maker agrees
to pay the Holder's reasonable costs (including reasonable attorney's fees and
court costs) in collecting this Note, including the reasonable costs of
obtaining and enforcing a judgment for any balance due on this Note.

     This Note has been executed in the City identified in the heading and
delivered to the Holder at the address stated herein. It is to be performed, in
whole or in part, in the State of California, and the laws of such state shall
govern the validity, construction, enforcement and interpretation of this Note.
Jurisdiction and venue for any action hereunder shall be in the County of the
City identified in the heading.

     The Maker represents that it is duly authorized and empowered to enter
into, deliver, perform and be fully bound by all of the terms, provisions and
conditions of this Note. The Maker also represents that the making and delivery
of this Note, and the performance of any agreement or instrument made in
connection herewith, does not conflict with or violate any other agreement to
which the Maker is a party.

     No provision of this Note shall require the payment or permit the
collection of interest in excess of the maximum permitted by law, and in the
event of any such excess, neither the Maker nor its successors or assigns shall
be obligated to pay any such excess to the extent that it is more than the
amount permitted by law. If an excess amount is received, charged, collected or
applied as interest, it shall automatically be made so as to reduce the rate to
that permitted by law and any excess interest then received, charged or
collected shall be applied to reduce the amount of any collateral to which the
Holder is entitled.

     In the event that any word, phrase, clause, sentence or other provision
hereof shall violate any applicable statute, ordinance or rule of law in any
jurisdiction in which it is used, such provision shall be ineffective to the
extent of such violation without invalidating any other provision hereof.

     IN WITNESS HEREOF, this Note is executed on the date and year above
written.

                                                                  EXHIBIT 10.216

                AMENDMENT TO COMPROMISE AND SETTLEMENT AGREEMENT


     This Amendment to Compromise and Settlement Agreement (the "Agreement") is
made and entered into on the date entered below by and between Fidelity Funding,
Inc. ("Fidelity") and Pollution Research and Control Corporation ("Pollution
Research"). Fidelity and Pollution Research are referred to herein singularly as
a "Party" and collectively as the "Parties."

     WHEREAS, on or about April 7, 1998 Fidelity filed suit in the 44th Judicial
District Court of Dallas County, Texas against Pollution Research in a case
styled Fidelity Funding, Inc. v. Pollution Research and Control Corporation and
numbered 98-02820-B (the "Lawsuit")' and,

     WHEREAS, on or about June 22, 1998 a Default Judgment was entered in the
Lawsuit in favor of Fidelity in the amount of $766,708.77 together with
attorneys' fees in the amount of $1,322.50, pre-judgment interest from and after
June 9, 1998 at the per diem rate of $326.42, costs and post-judgment interest
at the rate of 15% per annum (the "Judgment"); and,

     WHEREAS, pursuant to a Compromise Settlement and Release Agreement dated as
of August 12, 1999 certain agreements were reached between the Parties regarding
the Judgment and related matters (the "Original Settlement Agreement"); and

     WHEREAS, the Parties are desirous of modifying the Original Settlement
Agreement as set forth herein;

     NOW, THEREFORE, for and in consideration of the mutual promises and
covenants contained herein and for such other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged by the Parties,
Fidelity and Pollution Research agree as follows:

     1. Fidelity and Pollution Research agree and acknowledge that Fidelity has
incurred attorneys' fees from and after February 1, 2000 with its Texas and
California counsel in the aggregate amount not to exceed $5,000.00 (the
"Attorneys Fees"), and Pollution Research agrees to pay the Attorneys' Fees.

     2. Fidelity and Pollution Research agree and acknowledge that the total
outstanding amount of the Judgment as of March 23, 2000 is $483,949.27 (the
"Judgment Amount"), and that the outstanding portion of the Judgment Amount
shall accrue interest from and after March 23, 2000 at the rate of 15% per
annum. The Judgment Amount and Attorneys' Fees together with any interest
accruing on the Judgment Amount is referred to herein as the "Settlement
Amount".

     3. Contemporaneously with the execution of this Agreement and in no event
later than 5:00 p.m. on March 24, 2000, Pollution Research shall pay to Fidelity
the sum of $200,000.00 to be applied to the Settlement Amount as of the date of
receipt.




<PAGE>


     4. In consideration for such payment, for a period of 14 days from and
after the date hereof (the "Forbearance Period"), Fidelity shall forbear from
taking any affirmative action to collect and enforce the Judgment including, but
not limited to, execution, levy, garnishment, or attachment. In the event that
the Settlement Sum is not paid in full, immediately upon the expiration of the
Forbearance Period, Fidelity shall be fully entitled to enforce and collect the
unpaid portion of the Judgment and to pursue any and all remedies available to
it under applicable law to collect the unpaid portion of the Judgment and
Attorneys' Fees.

     5. Fidelity shall commence efforts to sell the Settlement Consideration
Shares (as that term is defined in the Original Settlement Agreement) and shall
deliver the Settlement Consideration Shares to Fred Ott together with documents
requested by Ott which are necessary to transfer the shares within three days
from the date hereof and in the event that the Settlement Consideration Shares
are sold during the Forbearance Period for an amount sufficient to satisfy the
outstanding balance of the Settlement Amount, any and all sale proceeds
remaining following the satisfaction of the outstanding balance of the
Settlement Amount and any unsold shares comprising the Settlement Consideration
Shares shall be returned to Pollution Research. If, however, the Settlement
Consideration Shares are sold and the proceeds from the sale are insufficient to
satisfy the outstanding balance of the Settlement Amount, Pollution Research
shall pay the shortfall together with any accrued but unpaid interest thereon.
Further, in the event that the Settlement Consideration Shares are sold
following the expiration of the Forbearance Agreement for an amount in excess of
the Settlement Amount, Fidelity shall be entitled to retain any such excess. For
purposes of this Agreement, the sale shall be deemed to be completed upon a
transfer of the shares provided, however, that the proceeds are distributed to
Fidelity within 10 days of such transfer.

     6. The Parties expressly agree and acknowledge that the Warrants (as that
term is defined in the Original Settlement Agreement) are expressly excluded
from the Settlement Consideration Shares. Pollution Research hereby agrees that
unless the Warrants are sold by Fidelity prior to such registration, Pollution
Research shall include the shares represented by the Warrants in its next
registration of shares. Pollution Research shall use its best efforts to
register the shares represented by the Warrants as soon as possible, and in any
event shall cause the shares represented by the Warrants to be registered on or
before the sixth month anniversary of this Agreement. Notwithstanding the
foregoing, Fidelity shall have the right but not the obligation to sell the
Warrants at any time during the six month period or thereafter.

     7. Upon payment in full of the Settlement Amount, Fidelity shall execute a
release of the Judgment.

     8. This Agreement shall be governed by and construed in accordance with the
laws of the state of Texas.

     9. All Parties to this Agreement have had the benefit of counsel of their
choice and have been afforded an opportunity to review this Agreement with their
chosen counsel.

<PAGE>


     10. This Agreement may be executed in a number of counterparts all of which
together shall for all purposes constitute one agreement, binding on all of the
Parties, notwithstanding that all of the Parties have not signed the same
counterpart, and it shall not be necessary to produce more than one counterpart
of this Agreement for evidentiary purposes.

     11. This Agreement may be modified by written instrument only, signed by
all Parties.

     SIGNED this 24th day of March, 2000.

THE WARRANT REPRESENTED BY THIS CERTIFICATE AND THE SHARES OF COMMON STOCK
ISSUABLE UPON THE EXERCISE OF THE WARRANT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR REGISTERED OR QUALIFIED UNDER
THE SECURITIES LAWS OF ANY STATE AND THUS MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED UNLESS REGISTERED UNDER THAT ACT AND REGISTERED OR QUALIFIED UNDER
APPLICABLE SECURITIES LAW OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION OR
QUALIFICATION IS AVAILABLE.


              WARRANT TO PURCHASE 87,141 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                               FROM MARCH 31, 2000
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON MARCH 31, 2003


     This certifies that, Phillip T. Huss or registered assigns, is entitled,
subject to the terms set forth below, to purchase from Pollution Research and
Control Corp., a California corporation (the "Company"), the above number of
fully paid and nonassessable shares of Common Stock of the Company ("Common
Stock") at a purchase price of Four Dollars ($4.00) per share ("Purchase
Price"). The Purchase Price and number of shares of Common Stock issuable upon
exercise hereof shall be subject to adjustment as provided in this Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on March 31, 2003, unless sooner exercise
is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.



<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder



<PAGE>


of such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.

6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     (a) The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

     (b) The Company shall use its best efforts, on or before October 1, 2000,
to file with the Securities and Exchange Commission (the "SEC"), a registration
statement on the appropriate Form under the Securities Act of 1933, covering the
sale by the Warrant holders in the open market of the shares of Common Stock
issuable upon exercise of the Warrants as well as other shares of the Company's
Common Stock owned by the Warrant holder. The Company also will undertake
reasonable best efforts to cause the registration statement to become effective
with the SEC as soon as possible after its filing. In addition, the Warrant
holder will have piggyback registration rights on any registration statement
filed by the Company (except on Forms S-8, S-4 or other non- applicable forms)
with respect to the shares underlying the Warrants.

<PAGE>


9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

THE  WARRANT  REPRESENTED  BY THIS  CERTIFICATE  AND THE SHARES OF COMMON  STOCK
ISSUABLE  UPON THE  EXERCISE OF THE WARRANT HAVE NOT BEEN  REGISTERED  UNDER THE

              WARRANT TO PURCHASE 187,858 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                               FROM MARCH 31, 2000
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON MARCH 31, 2003


     This certifies that, Ronald E. Patterson or registered assigns, is
entitled, subject to the terms set forth below, to purchase from Pollution
Research and Control Corp., a California corporation (the "Company"), the above
number of fully paid and nonassessable shares of Common Stock of the Company
("Common Stock") at a purchase price of Four Dollars ($4.00) per share
("Purchase Price"). The Purchase Price and number of shares of Common Stock
issuable upon exercise hereof shall be subject to adjustment as provided in this
Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on March 31, 2003, unless sooner exercise
is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.




<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have  become the holder



<PAGE>


of such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial

loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the

Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

THE WARRANT REPRESENTED BY THIS CERTIFICATE AND THE SHARES OF COMMON STOCK
ISSUABLE UPON THE EXERCISE OF THE WARRANT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR REGISTERED OR QUALIFIED UNDER
THE SECURITIES LAWS OF ANY STATE AND THUS MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED UNLESS REGISTERED UNDER THAT ACT AND REGISTERED OR QUALIFIED UNDER
APPLICABLE SECURITIES LAW OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION OR
QUALIFICATION IS AVAILABLE.

              WARRANT TO PURCHASE 46,875 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                               FROM MARCH 31, 2000
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON MARCH 31, 2003


     This certifies that, Lee Sion or registered assigns, is entitled, subject
to the terms set forth below, to purchase from Pollution Research and Control
Corp., a California corporation (the "Company"), the above number of fully paid
and nonassessable shares of Common Stock of the Company ("Common Stock") at a
purchase price of Three Dollars and 10/100 ($3.10) per share ("Purchase Price").
The Purchase Price and number of shares of Common Stock issuable upon exercise
hereof shall be subject to adjustment as provided in this Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on March 31, 2003, unless sooner exercise
is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.




<PAGE>

     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have  become the holder



<PAGE>


of such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>

6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     (a) The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

     (b) The Company shall use its best efforts, on or before October 1, 2000,
to file with the Securities and Exchange Commission (the "SEC"), a registration
statement on the appropriate Form under the Securities Act of 1933, covering the
sale by the Warrant holders in the open market of the shares of Common Stock
issuable upon exercise of the Warrants as well as other shares of the Company's
Common Stock owned by the Warrant holder. The Company also will undertake
reasonable best efforts to cause the registration statement to become effective
with the SEC as soon as possible after its filing. In addition, the Warrant
holder will have piggyback registration rights on any registration statement
filed by the Company (except on Forms S-8, S-4 or other non- applicable forms)
with respect to the shares underlying the Warrants.

<PAGE>


9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of

Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in

Common Stock which that holder would have become entitled to purchase but for

the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>

6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     (a) The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

     (b) The Company shall use its best efforts, on or before October 1, 2000,
to file with the Securities and Exchange Commission (the "SEC"), a registration
statement on the appropriate Form under the Securities Act of 1933, covering the
sale by the Warrant holders in the open market of the shares of Common Stock
issuable upon exercise of the Warrants as well as other shares of the Company's
Common Stock owned by the Warrant holder. The Company also will undertake
reasonable best efforts to cause the registration statement to become effective
with the SEC as soon as possible after its filing. In addition, the Warrant
holder will have piggyback registration rights on any registration statement
filed by the Company (except on Forms S-8, S-4 or other non- applicable forms)
with respect to the shares underlying the Warrants.

<PAGE>


9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

THE WARRANT REPRESENTED BY THIS CERTIFICATE AND THE SHARES OF COMMON STOCK
ISSUABLE UPON THE EXERCISE OF THE WARRANT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR REGISTERED OR QUALIFIED UNDER
THE SECURITIES LAWS OF ANY STATE AND THUS MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED UNLESS REGISTERED UNDER THAT ACT AND REGISTERED OR QUALIFIED UNDER
APPLICABLE SECURITIES LAW OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION OR
QUALIFICATION IS AVAILABLE.

              WARRANT TO PURCHASE 10,000 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                               FROM MARCH 31, 2000
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON MARCH 31, 2003


     This certifies that, Patricia Cudd or registered assigns, is entitled,
subject to the terms set forth below, to purchase from Pollution Research and
Control Corp., a California corporation (the "Company"), the above number of
fully paid and nonassessable shares of Common Stock of the Company ("Common
Stock") at a purchase price of Four Dollars ($4.00) per share ("Purchase
Price"). The Purchase Price and number of shares of Common Stock issuable upon
exercise hereof shall be subject to adjustment as provided in this Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on March 31, 2003, unless sooner exercise
is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.




<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have  become the holder



<PAGE>


of such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for
such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.



<PAGE>

6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by
certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,



<PAGE>


liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     (a) The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

     (b) The Company shall use its best efforts, on or before October 1, 2000,
to file with the Securities and Exchange Commission (the "SEC"), a registration
statement on the appropriate Form under the Securities Act of 1933, covering the
sale by the Warrant holders in the open market of the shares of Common Stock
issuable upon exercise of the Warrants as well as other shares of the Company's
Common Stock owned by the Warrant holder. The Company also will undertake
reasonable best efforts to cause the registration statement to become effective
with the SEC as soon as possible after its filing. In addition, the Warrant
holder will have piggyback registration rights on any registration statement
filed by the Company (except on Forms S-8, S-4 or other non- applicable forms)
with respect to the shares underlying the Warrants.

<PAGE>


9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was



<PAGE>


surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for


<PAGE>


such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by



<PAGE>


certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     (a) The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

     (i)  will take all necessary or appropriate action in order that the
          Company may validly and legally issue fully paid and nonassessable
          shares of Common Stock on exercise of this Warrant;

     (ii) will not increase the par value of the shares of Common Stock
          receivable on the exercise of this Warrant above the amount payable
          for those shares on such exercise; and

     (iii) will at all times reserve and keep available, solely for issuance
          upon exercise of this Warrant, all shares of Common Stock or other
          securities from time to time issuable upon exercise of this Warrant.

     (b) The Company shall use its best efforts, on or before October 1, 2000,
to file with the Securities and Exchange Commission (the "SEC"), a registration
statement on the appropriate Form under the Securities Act of 1933, covering the
sale by the Warrant holders in the open market of the shares of Common Stock
issuable upon exercise of the Warrants as well as other shares of the Company's
Common Stock owned by the Warrant holder. The Company also will undertake
reasonable best efforts to cause the registration statement to become effective
with the SEC as soon as possible after its filing. In addition, the Warrant
holder will have piggyback registration rights on any registration statement
filed by the Company (except on Forms S-8, S-4 or other non- applicable forms)
with respect to the shares underlying the Warrants.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder  of the Company for any purpose, nor



<PAGE>


shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.


15. AMENDMENT.

instrument signed by the Company and the holder of this Warrant.

              WARRANT TO PURCHASE 25,000 SHARES OF COMMON STOCK OF

                               FROM MARCH 31, 2000
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON MARCH 31, 2003

subject to the terms set forth below, to purchase from Pollution Research and
Control Corp., a California corporation (the "Company"), the above number of
fully paid and nonassessable shares of Common Stock of the Company ("Common

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on March 31, 2003, unless sooner exercise

the obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means

similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was



<PAGE>


surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for




<PAGE>


such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by



<PAGE>


certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

          (i)  will take all necessary or appropriate action in order that the
               Company may validly and legally issue fully paid and
               nonassessable shares of Common Stock on exercise of this Warrant;

          (ii) will not increase the par value of the shares of Common Stock
               receivable on the exercise of this Warrant above the amount
               payable for those shares on such exercise; and

          (iii) will at all times reserve and keep available, solely for
               issuance upon exercise of this Warrant, all shares of Common
               Stock or other securities from time to time issuable upon
               exercise of this Warrant.

     (b) The Company shall use its best efforts, on or before October 1, 2000,
to file with the Securities and Exchange Commission (the "SEC"), a registration
statement on the appropriate Form under the Securities Act of 1933, covering the
sale by the Warrant holders in the open market of the shares of Common Stock
issuable upon exercise of the Warrants as well as other shares of the Company's
Common Stock owned by the Warrant holder. The Company also will undertake
reasonable best efforts to cause the registration statement to become effective
with the SEC as soon as possible after its filing. In addition, the Warrant
holder will have piggyback registration rights on any registration statement
filed by the Company (except on Forms S-8, S-4 or other non- applicable forms)
with respect to the shares underlying the Warrants.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.

THE WARRANT REPRESENTED BY THIS CERTIFICATE AND THE SHARES OF COMMON STOCK
ISSUABLE UPON THE EXERCISE OF THE WARRANT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR REGISTERED OR QUALIFIED UNDER
THE SECURITIES LAWS OF ANY STATE AND THUS MAY NOT BE OFFERED, SOLD OR OTHERWISE
TRANSFERRED UNLESS REGISTERED UNDER THAT ACT AND REGISTERED OR QUALIFIED UNDER
APPLICABLE SECURITIES LAW OR UNLESS AN EXEMPTION FROM SUCH REGISTRATION OR

              WARRANT TO PURCHASE 33,333 SHARES OF COMMON STOCK OF
                      POLLUTION RESEARCH AND CONTROL CORP.

                               FROM MARCH 31, 2000
            VOID AFTER 5:00 P.M., LOS ANGELES TIME, ON MARCH 31, 2003


     This certifies that, Maria Molinsky or registered assigns, is entitled,
subject to the terms set forth below, to purchase from Pollution Research and
Control Corp., a California corporation (the "Company"), the above number of
fully paid and nonassessable shares of Common Stock of the Company ("Common
Stock") at a purchase price of Four Dollars ($4.00) per share ("Purchase
Price"). The Purchase Price and number of shares of Common Stock issuable upon
exercise hereof shall be subject to adjustment as provided in this Warrant.

     This Warrant is exercisable at any time, or from time to time, to and
including 5:00 p.m., Los Angeles time, on March 31, 2003, unless sooner exercise
is required pursuant to the terms of this Warrant.

     DEFINITIONS.

     As used in this Warrant, the following terms, unless the context otherwise
requires, have the following meanings:

     1.1 "Company" includes any corporation which shall succeed to or assume the
obligations of the Company under this Warrant.

     1.2 "Common Stock," when used with reference to stock of the Company, means
all shares, now or hereafter authorized, of the class of the Common Stock of the
Company presently authorized and stock of any other class into which those
shares may hereafter be changed.

<PAGE>


     1.3 The terms "Warrant holder," "holder of this Warrant," "holder," or
similar terms when the context refers to a holder of the Warrant, refers to any
person who shall at the time be the registered holder of the Warrant.

2. EXERCISE.

     The holder of this Warrant may exercise it in full by surrender of this
Warrant, with the form of subscription at the end of this warrant duly executed
by the holder, to the Company at its principal office, accompanied by payment in
the amount obtained by multiplying the Purchase Price by the number of shares of
Common Stock specified on the face of this warrant as may be adjusted pursuant
to the terms of this Warrant. Payment shall be made in cash, cashier's or
certified check payable to the Company, by the surrender of any notes of the
Company having an unpaid principal and interest balance at least equal to such
payment (designating the portion of such balance to be applied), or by any
combination of such methods.

     The holder of this Warrant may exercise it in part by surrendering it,
accompanied by payment as provided above, except that the amount payable by the
holder on such partial exercise shall be the amount obtained by multiplying the
Purchase Price by the number of shares of Common Stock (without giving effect to
any adjustment of that number) designated by the holder in a written statement
accompanying this Warrant. On partial exercise, the Company shall, unless this
Warrant has expired, promptly issue and deliver to the holder of this Warrant a
new Warrant or Warrants of like tenor and dated the date hereof in the name of
that holder providing for the right to purchase that number of shares of Common
Stock (without giving effect to any adjustment of that number) for which this
Warrant has not been exercised.

     In the event the Common Stock issuable upon exercise of this Warrant is not
then registered under the Securities Act of 1933, as amended, the holder of this
Warrant shall, upon exercise of this Warrant, deliver to the Company an
investor's certificate with respect to such shares to the effect that such
shares are being acquired for investment purposes only and for its own account,
and not as a nominee or agent for any other person and not with a view to, or
for resale in connection with, any distribution thereof within the meaning of
the Securities Act of 1933, as amended.

3. ISSUANCE OF CERTIFICATES.

     As soon as possible after full or partial exercise of this Warrant, the
Company, at its expense, will cause to be issued in the name of and delivered to
the holder of this Warrant, a certificate, or certificates, for the number of
fully paid and nonassessable shares of Common Stock to which that holder shall
be entitled on such exercise, together with any other securities and property to
which that holder is entitled on such exercise under the terms of this Warrant.
The person in whose name any certificate for shares of Common Stock is issued
upon exercise of this Warrant shall for all purposes be deemed to have become
the holder of record of such shares on the date on which this Warrant was



<PAGE>


surrendered and payment of the Purchase Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Company are closed, such person shall be deemed to have become the holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open. No fractional share will be issued on exercise of
rights to purchase under this Warrant. If on any exercise of this Warrant, a
fraction of a share results, the Company will pay the cash value of that
fractional share, calculated on the basis of the Purchase Price.

4. SUBDIVISIONS OR COMBINATIONS.

     If, at any time during the term hereof, the number of shares of Common
Stock outstanding is increased by a stock dividend payable in shares of Common
Stock or by a subdivision or split-up, then, immediately following the record
date fixed for the determination of holders of Common Stock entitled to receive
such stock dividend, subdivision or split-up, the number of shares of Common
Stock issuable upon exercise of this Warrant shall be increased and the Purchase
Price shall be decreased in proportion to such increase in outstanding shares.
If at any time during the term hereof the number of shares of Common Stock
outstanding is decreased by a combination of the outstanding shares of Common
Stock, immediately following the record date for such combination, the number of
shares of Common Stock issuable upon exercise of this Warrant shall be decreased
and the Purchase Price shall be increased in proportion to such decrease in
outstanding shares.

     If the Company shall, at any time, subdivide or combine its outstanding
shares of Common Stock, pay a dividend of other securities to the holders of
such shares, or pay a dividend of shares of Common Stock to holders of any such
stock of the Company of any class, this Warrant shall, after that subdivision,
combination, or dividend, evidence the right to purchase the number of shares of
Common Stock or other securities that would have been issuable to the holder of
this Warrant as a result of that subdivision, combination or dividend with
respect to the shares of Common Stock which were purchasable under this Warrant
immediately before that subdivision, combination, or dividend or any record date
thereafter. If the Company shall at any time subdivide the outstanding shares of
Common Stock, the Purchase Price then in effect immediately before that
subdivision shall be proportionately decreased, and, if the Company shall at any
time combine the outstanding shares of Common Stock, the Purchase Price then in
effect immediately before that combination shall be proportionately increased.
Any judgment under this Section 4 shall become effective at the close of
business on the date the subdivision, combination or dividend becomes effective
retroactive to the record date therefor, if any.

5. REORGANIZATION, RECLASSIFICATION.

     If the Common Stock issuable on exercise of this Warrant shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification, or otherwise (other
than a subdivision or combination of shares provided for above, the holder of
this Warrant shall, on its exercise, be entitled to purchase, in lieu of the
Common Stock which that holder would have become entitled to purchase but for




<PAGE>


such change, a number of shares of such other class or classes of stock which
the holder of this Warrant would have owned or have been entitled to receive
after such change, had this Warrant been exercised immediately before that
change or any record date therefor.


6. CONSOLIDATION, MERGERS.

     If at any time there shall be a capital reorganization of the Common Stock
issuable upon exercise of this Warrant (other than a combination,
reclassification, exchange or subdivision of shares provided for elsewhere in
this Warrant) or a merger or consolidation of the Company with or into another
corporation, or the sale of the Company's properties and assets as, or
substantially as, an entirety to any other person, then, as a part of such
reorganization, merger, consolidation, or sale, lawful provision shall be made
so that the holder of this Warrant shall thereafter be entitled to receive on
exercise of this Warrant, during the period specified in this Warrant and on
payment of the Purchase Price then in effect, the number of shares of stock or
other securities or property of the Company, or of the successor corporation
resulting from such merger or consolidation, to which a holder of the Common
Stock deliverable on exercise of this Warrant would have been entitled on such
capital reorganization, merger, consolidation, or sale. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interests of the holder of this Warrant after the
reorganization, merger, consolidation, or sale such that the provisions of this
Warrant (including adjustments of the Purchase Price then in effect and number
of shares purchasable on exercise of this Warrant) shall be applicable after
that event, as near as reasonably may be, in relation to any shares or other
property deliverable after that event on exercise of this Warrant.

7. NOTICE.

     The Company shall promptly give written notice of each adjustment of the
Purchase Price or the number of shares of Common Stock or other securities
issuable on exercise of this Warrant, by certified mail, return receipt
requested, postage prepaid, to the registered holder of this Warrant at that
holder's address as shown on the Company's books. The notice shall state the
adjustment and show in reasonable detail the facts on which that adjustment is
based.

     If (i) the Company shall pay any dividend payable in stock on its Common
Stock or make any other distributions to the holders of its Common Stock (other
than a dividend in Common Stock exempt from the adjustment provisions of this
Warrant), or (ii) the Company shall offer for subscription pro rata to the
holders of its Common Stock any additional shares of stock of any class or any
other rights, or (iii) there shall be any capital reorganization or
reclassification of the Company's Common Stock or consolidation or merger of the
Company with or into another corporation, or (iv) there shall be any sale of all
or substantially all of the Company's properties and assets, or (v) there shall
be a voluntary of involuntary dissolution, liquidation, or winding up of the
Company, or (vi) the Company shall have received an offer approved by the Board
of Directors to purchase all or substantially of its assets; then, in each case,
the Company shall give at least 15 calendar days prior written notice (by



<PAGE>


certified mail, return receipt requested) to the registered holder of this
Warrant at the address of that holder shown on the books of the Company, of the
date as of which the books of the Company shall close or a record shall be taken
for such dividend, distribution, or subscription rights, or the date as of which
the reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up shall take place. That notice shall also specify the
date as of which the holders of the Common Stock of record shall participate in
that dividend, distribution, or subscription rights, or shall be entitled to
exchange their Common Stock for securities or other property deliverable on such
reorganization, reclassification, consolidation, merger, sale, dissolution,
liquidation, or winding up (on which date, in the event of voluntary or
involuntary dissolution, liquidation, or winding up of the Company, or
consolidation or merger in which the Company is not a surviving entity or
becomes a wholly-owned subsidiary, the right to exercise this Warrant shall
cease).


8. COVENANTS.

     (a) The Company covenants that it will not, by amendment of its articles of
incorporation or through any reorganization, transfer of assets, consolidation,
merger, dissolution, issue or sale of securities, or any other voluntary action
avoid, or seek to avoid, the observance or performance of any of the terms of
this Warrant, but will, at all times and in good faith, assist in carrying out
all those terms and in taking all action necessary or appropriate to protect the
rights of the holder of this Warrant against other impairment. Without limiting
the generality of the above provision, the Company:

          (i)  will take all necessary or appropriate action in order that the
               Company may validly and legally issue fully paid and
               nonassessable shares of Common Stock on exercise of this Warrant;

          (ii) will not increase the par value of the shares of Common Stock
               receivable on the exercise of this Warrant above the amount
               payable for those shares on such exercise; and

          (iii) will at all times reserve and keep available, solely for
               issuance upon exercise of this Warrant, all shares of Common
               Stock or other securities from time to time issuable upon
               exercise of this Warrant.

     (b) The Company shall use its best efforts, on or before October 1, 2000,
to file with the Securities and Exchange Commission (the "SEC"), a registration
statement on the appropriate Form under the Securities Act of 1933, covering the
sale by the Warrant holders in the open market of the shares of Common Stock
issuable upon exercise of the Warrants as well as other shares of the Company's
Common Stock owned by the Warrant holder. The Company also will undertake
reasonable best efforts to cause the registration statement to become effective
with the SEC as soon as possible after its filing. In addition, the Warrant
holder will have piggyback registration rights on any registration statement
filed by the Company (except on Forms S-8, S-4 or other non- applicable forms)
with respect to the shares underlying the Warrants.

9. CHANGES IN WARRANT.

     The form of this Warrant need not be changed because of any adjustment in
the Purchase Price or in the number of shares of Common Stock purchasable upon
its exercise. A Warrant issued after any such adjustment or any partial exercise
or in replacement may continue to express the same Purchase Price and the same
number of shares of Common Stock (appropriately reduced in the case of partial
exercise) as are stated on the face of this Warrant as initially issued, and
that Purchase Price and the number of shares shall be considered to have been so
changed as of the close of business on the date of adjustment.

10. LOST CERTIFICATES.

     Upon receipt of evidence reasonably satisfactory to the Company of the
loss, theft, destruction, or mutilation of this Warrant, upon delivery of any
indemnity agreement or bond reasonably satisfactory in form and amount to the
Company or, in the case of mutilation, on surrender and cancellation of this
Warrant, the Company, at its expense, will execute and deliver, in lieu of this
Warrant, a new Warrant of like tenor.

11. TRANSFERABILITY.

     This Warrant shall not be transferred or assigned unless the Company
receives an opinion of counsel reasonably acceptable to the Company (which
counsel may be counsel for the Company), stating that such transfer is exempt
from the registration requirements of the Securities Act of 1933, as amended,
and the registration and qualification requirements under applicable state law.

12. GOVERNING LAW.

     This Warrant shall be governed by and construed and enforced in accordance
with the laws of California.

13. TAXES.

     The Company shall pay all documentary, stamp or other transactional taxes
attributable to the issuance or delivery of shares of Common Stock of the
Company upon exercise of all or any part of this Warrant; provided, however,
that the Company shall not be required to pay any taxes which may be payable in
respect of any transfer involved in the issuance or delivery of any certificate
for such shares in a name other than that of the holder of this Warrant.

<PAGE>


14. RIGHTS OF WARRANT HOLDER.

     No holder of this Warrant, as such, shall be entitled to vote or receive
dividends or be considered a shareholder of the Company for any purpose, nor
shall anything in this Warrant be construed to confer on any holder of this
Warrant, as such, any rights of a shareholder of the Company or any right to
vote, give or withhold consent to any corporate action, to receive notice of
meetings of shareholders, to receive dividends or subscription rights or
otherwise.


15. AMENDMENT.

     This Warrant and any of its terms may be changed only by a written
instrument signed by the Company and the holder of this Warrant.
