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."

     Because  severe  competitive  price  pressures  in its core  business  have
developed (see "History of the Company" below),  the Company has during the past
few years,  pursued various areas of diversification of its developed technology
primarily including air pollution control of flue gas-emitted air pollutants and
medical,   asthma-related,   diagnostic   instrumentation.   At  this   time  no
diversification  is being  pursued  (See  "Instrumentation  Market" and "Control
Market"  below) and singular  focus is being  applied to the "core  business" as
described above.

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. (See Item
9. "Directors, Executive Officers, Promoters and Control Person; Compliance with
Section  16(a) of the  Exchange  Act -  Directors,  Executive  Officers  and Key
Employees.")

     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.")


                                        4


<PAGE>



     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.

     In March 1994, the Company entered into an exclusive worldwide requirements
agreement  over a  three-year  period with  London-based  Logan  Research,  Ltd.
("LRL")  to  provide  LRL with  oxides of  nitrogen  instrument  parts on an "as
required" basis for use in medical technology applications. In October 1995, the
agreement  was  modified  to be  exclusive  with a domestic  corporation,  Logan
Medical  Devices  ("LMD"),  which  acquired  Logan  Research,  Ltd. In 1995, the
Company advanced $164,000 to LRL. The $164,000 was charged against operations in
1995.  In June 1996 the  Company  acquired  100% of the common  stock of LMD for
150,125  options to LMD  shareholders,  all options  above  market bid price and
vesting in January, 1998, such bid price as existed in the date of agreement. In
addition, the Company contributed $250,000 to LMD for working capital.

     Also, in June, 1996, the Company acquired 100% of the stock of Nutek, Inc.,
a  Pensacola,  Florida,  electrical  control  panel and  printed  circuit  board
manufacturer.  No company stock was issued,  but 85,000  options at above market
bid  price  on the  date of  agreement  were  issued  to key  employees  in this
transaction,  lawyers and  "finders."  Such options  vested in January 1998. The
Company  directly paid $250,000 cash into an estimated  total  purchase price of
$1,900,000,  the balance  obtained from asset based financing  solely on Nutek's
assets.  The Company  acquired Nutek primarily for the customer list as it would
fit into the Company's air pollution control technology diversification plans.

     In January,  1998, the the Company began a reorganization  program designed
to focus on its "core business" alone. 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.  The  initial  step  of  the  reorganization  was
dissolution  of the Nutek  subsidiary  and  separation of "LRL" from "LMD".  The
Company is involved in significant  litigation  regarding the Nutek dissolution.
(See Item 3. "Legal Proceedings.")

     In June, 1998, the Company signed a $5.1 million dollar contract with China
to supply  equipment  and software to monitor air  pollution  in eleven  cities.
Initiation of the work was contingent on final agreement  between China and U.S.
banks and the Export-Import Bank (Ex-Im) guarantee for financing arranged by the
Company.  Financing was expected to be completed  within a few months,  however,
the Company has been informed that the earliest date for Ex-Im approval is March
29, 1999. (See "Foreign  Sales.")  Concurrently,  the Company requires  in-house
financing  for above normal  working  capital  needs for a project  considerably
larger than previously experienced. At this time management believes the Company
can obtain,  at least, a minimum  required  through debt financing.  There is no
assurance  that the  Company  can  obtain  more than a minimum to  initiate  the
project by debt  financing,  in which  case,  the  Company  would be required to
pursue  equity  financing  in which  the  Company  has  demonstrated  successful
experience.

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.

     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


                                        6


<PAGE>



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.

     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
"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  microprocessor  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 and currently foreign sales represent approximately 50 percent
of the Dasibi Environmental subsidiary - the core business.

<PAGE>



     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 1999, 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 five
years  to  over  300  customers  in  over  30  countries,  including  industrial
manufacturers;  federal,  state, city, local and foreign governmental  agencies;
and educational and research  institutions.  However,  a significant loss in the
number of government  agencies,  industrial companies or research agencies which
typically  purchase  the  Company's  instruments  could have a material  adverse
effect  on the  Company.  Similarly  in 1999,  the loss of  China  would  have a
material adverse effect on the Company.

     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, 1998 was  approximately
$5,500,000 which amount the Company considers material.  However,  $5,100,000 of
this backlog was due to the China contract,  discussed  below,  which,  although
formally signed, had a contingency of no shipments until "bank to bank" document
financing  was  completed.  As of March  22,  1999 this  financing  has not been
completed, although Ex-Im Bank approval was received.

Foreign Sales

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

                                                               Year Ended

Aggregate sales to unaffiliated foreign customers:

Europe and The United Kingdom                              $  987       $1,104

Asia and Pacific Rim                                       $  934       $  622

Latin America & Other                                      $  397       $  434

     During the fiscal  years ended  December  31, 1997 & 1998,  no one customer
accounted for more than 10% of net sales.

     In  June  1998,   the  Company  was  awarded  a  contract  from  China  for
installation of the Company's systems in an eleven city network. Since November,
1995, the Company negotiated U.S. Export-Import financing for China specifically
for this project.  Technical and contractual  negotiations were concluded at the
June award at The People's  Hall in Beijing.  Financing  aspects of the project,
however,  required nearly nine months of apparently  normal bank to bank delays.


                                       10


<PAGE>


Because  it is not  possible  to define a time  frame to  anyone of three  banks
involved, the backlog of the China project is not considered "firm", until Ex-Im
Bank approval  received on March 22, 1999 is  supplemented  with  completed bank
agreements.

     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,
1998,  the Company had  approximately  $300,000 in "firm" orders which  required
delivery  in 90 days or less,  a backlog  which the  Company  does not  consider
significant.   The  $5,100,000   additional   backlog  attributed  to  China  is
significant  to the  Company  since it is long term (8  months)  in  nature  and
therefore should allow cost saving benefits of manufacture planning and quantity
purchase discounts.

Manufacturing and Purchasing

     The Company  manufactures  many  components  and  subsystems for use in its
products,   including   critical  optical  components  and  analog  and  digital
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 price pressure  demands,  the Company has been limiting Flue Gas
Purification System development work.

Employees

     As of March 22,  1999,  the Company had 31 full-time  employees,  of whom 5
were engaged in administration,  3 in engineering,  21 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.

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 $30,000
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.

     In May, 1998, the Company  acquired a facility  consisting of approximately
3000 square  feet and  located in Macao,  China.  The  facility  was needed as a


                                       12


<PAGE>



and training center for an anticipated China contract.  (See "History of Company
and Recent  Developments.") A lease back agreement with an affiliated company in
Macau, PIC Computers, Ltd.("PIC") calls for $8,000 per month rent to the Company
while PIC performs  service and training for China  requirements  under specific
contracts  furnished  as  needed  from  the  Company.  (See  Item  12.  "Certain
Relationships and Related Transactions.") No lease payments are due, nor are any
contracts  contemplated  until the China contract  shipments begin. The facility
therefore  is not  utilized  at this  time,  and no  lease  payments  are due or
accrued.


Item 3.                    Legal Proceedings

Turbodyne
- ---------
     In  August,   1998,  the  Company  executed  an  agreement  with  Turbodyne
Technologies, Inc. which was subsequently wrongfully repudiated by Turbodyne. On
October 2, 1998,  the Company  filed suit in the Superior  Court of the State of
California,  which case is entitled Pollution Research and Control Corp., Dasibi
Environmental  Corp. and Logan Medical Devices v. Turbodyne  Technologies,  Inc.
and Does 1 through 100,  inclusive,  Case No. BC 198 521. The complaint  alleges
that Turbodyne breached an agreement to purchase the Company's two subsidiaries,
Dasibi  Environmental  Corp. and Logan Medical Devices when Turbodyne  willfully
repudiated  its contract with the Company  shortly after signing and  delivering
it.  The  Complaint  alleges  that  Turbodyne's  actions  constituted  breach of
contract,  a breach of the covenant of good faith and fair dealing,  intentional
interference with prospective business advantage and negligent interference with
prospective  business  advantage.  The  Complaint  seeks  compensatory  damages,
punitive damages and declaratory relief.

Fidelity Funding
- ----------------
     In seeking to focus on its core  business  the  Company  attempted  to sell
Nutek. This attempt failed.  Management then decided that every effort should be
made to maximize the  liquidated  value of  fabrication  equipment  and that the
"printed circuit board" portion of Nutek,  Inc. had operating value as a vehicle
to eventually pay off deficiency  sums, if any, and unsecured  creditors.  Nutek
was therefore  placed into Chapter 11  reorganization.  The major secured lender
opposed this filing and at a June 19, 1998 hearing before the Bankruptcy  Court,
prevailed  against Nutek,  Inc. in having the Bankruptcy  Code's automatic stay,
imposed when the case was filed, vacated, to permit a secured lender sale of the
mortgaged  property based  principally upon the secured lender's  assertion that
the assets of Nutek,  Inc. were  insufficient to cover the amount of the secured
loans.  The  assertion was supported by a "new"  appraisal  which  management of
Nutek,  Inc. had not seen until the  proceedings  were  commenced by the secured
lender to vacate the  automatic  stay.  From an original  1996  appraisal  which
disclosed a forced  liquidation value for the mortgaged  property of $1,200,000,
the new  appraisal  indicated  an  apparent  value  of  approximately  $341,000.
Management believes that there is the possibility of questionable  activities on
the  "selling"  side in the  original  1996  purchase  of  Nutek,  Inc.  and the
financing  with the secured lender and appraisal  obtained and utilized,  and is
investigating the role of all parties involved in the acquisition and financing.
An auction sale was held by the secured  lender on July 28, 1998 which  realized
only  $160,000.  On July 1,  1998,  the  Company  received  a notice of  default
Judgment against the Company's  guarantee of debt entered in a Texas State court
in the sum of  $766,708.77.  The Company has  retained  Texas  counsel,  filed a
Notice of Removal of the Texas  State court case to the United  States  District


                                       13


<PAGE>



Court Northern  District of Texas,  Dallas  Division,  and has filed a Motion to
dismiss  and/or quash service of process and to set aside the Default  Judgment.
Although  the  matter  is still  pending,  the  amount of the  Default  Judgment
described  above has been reduced to  approximately  $400,000 by  collection  of
Nutek  receivables.  The Company has  established a reserve of $350,000 for this
matter.

Item 4.          Submission of Matters to a Vote of Security Holders

     On May 6, 1998,  the Board of Directors  voted in favor of a reverse  stock
split of the Company's  issued and  outstanding  shares of common stock,  no par
value  per  share  (the  "Common  Stock")  on May 15,  1998 on the  basis of the
conversion of each four shares of Common Stock then issued and outstanding  into
one share of Common Stock (the  "Reverse  Split") and directed  that the Reverse
Stock Split be placed on the agenda for  consideration  by  shareholders  at the
Annual Meeting.  The Board of Directors believed that the per share price of the
Company's  Common  Stock  prior  to  May  15,  1998,   negatively  impacted  the
marketability of the existing  shares,  the amount and percentage of transaction
costs paid by individual  shareholders and the potential  ability of the Company
to raise capital by issuing new shares.

     At the Annual Meeting held on October 15, 1998, the  shareholders  approved
the Reverse Stock Split so that the number of issued and  outstanding  shares of
Common Stock of the Company was reduced from 8,673,732  shares to  approximately
2,168,433 shares,  based upon the total number of issued and outstanding  shares
of the Company's Common Stock as of May 15, 1998.

     An affirmative  vote of a majority of the shares of Common Stock present or
represented  by proxy and voting at the Annual Meeting was received for approval
of the proposal with the following vote:

         For                 1,588,397
         Against                55,736
         Abstain                10,147

     The  following  members of the Board of Directors  were  re-elected  at the
Annual Meeting with the following vote:

     Additionally,  the firm of AJ.  Robbins,  P.C. was elected as the Company's
auditors for the fiscal year ending December 31, 1998 with the following vote:

     As of March 19, 1999, the  approximate  number of shareholders of record of
the Company's Common Stock was 1,100. The Company has never paid or declared any
dividends on its Common Stock and does not  anticipate  paying  dividends in the
foreseeable future.

     A one for four reverse split was approved by shareholders  during 1998 (See
Item 4.  "Submission of Matters to a Vote of Security  Holders.") and all values
pertaining to the Company's stock have been adjusted in this report. As of March
22,  1999,  there are  3,277,438  shares of Common  Stock  outstanding,  541,708
warrants and 915,500 options.

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

     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 revenue  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


                                       16

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  revenues  were
obtained  during  1998.  This  banking  delay has  continued to the date of this
report.

     Net revenues in 1998 were $2,808,000  compared to $6,793,000 in 1997, a 59%
decrease.  The decrease was entirely  due to the  discontinuance  of  subsidiary
business.  The revenues for the core business were  essentially  the same as the
year before.

     Gross margin was 35% of  consolidated  net revenues in 1998 compared to 20%
of the  consolidated  revenues of 1997.  The increase in gross margin was due to
the disposition of the subsidiary businesses.

     Selling, general and administrative expenses decreased from a
consolidated $2,495,000 in 1997 to $1,584,000 in 1998.

     Research and development expense was essentially unchanged.

     Interest  expense  decreased  from  $233,000  in 1997 to  $28,000  in 1998,
primarily due to the elimination of subsidiary financing in 1997.

     Because  of the  disposition  of  subsidiary  assets  in 1998  the  Company
sustained a net loss from discontinued operations of $1,034,000.

     The core business  sustained a loss of $527,000 from continuing  operations
primarily due to increased  staffing and related expenses in anticipation of the
China contract performance which failed to commence during 1998.

     As a result  of the  foregoing  factors,  net loss was  $1,561,000  in 1998
compared to a net loss of $1,231,000 in 1997.

     Comprehensive  loss  is  comprised  of  the  foreign  currency  translation
adjustment  and  the  change  in  unrealized  gain  on  marketable   securities.
Comprehensive  loss was  $27,837 in 1998  compared  to a  comprehensive  loss of
$117,988 in 1997.

     The Company  initiated  attempts  to sell Nutek on February  16, 1998 which
were   unsuccessful  and  resulted  in  a  Chapter  XI  filing  with  subsequent
liquidation.

     Even though the 1997  liquidation  appraisal of the subsidiary Nutek assets
was  indicated as  approximately  $1,200,000,  the actual  liquidation  realized
$160,000  in  July  1998.  These  proceeds  plus  the  Nutek   receivables  were
approximatley  $400,000 short of the amount due under a guaranty by the Company.
A  reserve  of  $350,000  has  been  established  and is part  of the  indicated
$1,034,000 loss from discontinued operations.

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.  Current
market value of the Company's Common Stock does not preclude this approach as of
this date.

     Since January 1998, the Company has raised  $697,569 in private  placements
which  have  resulted  in the  issuance  of 854,005  shares of Common  Stock and
253,874 options and warrants.

     Working  capital at December 31, 1998 was $1,376,000.  Management  believes
that the  anticipated  cash flows from operations will be sufficient to meet the
Company's  short-term  cash  needs.  As of March 19,  1999,  the  Company had no
material commitments for capital expenditures.

     Cash  decreased  from  $515,000 at the end of 1997 to $64,000 at the end of
1998.  The inventory  purchased in  anticipation  of performance of the contract
with  China was  increased  $333,000  and  long-term  liabilities  were  reduced
$291,000 during 1998.

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

Year 2000 Compliance

     General.  The Company  believes it has  completed  all internal  efforts to
avoid the adverse effects of the Year 2000 issue.

     State of Readiness.  The Company received certifications of compliance from
all vendors deemed material to its business  operations during the first quarter
of 1999.

     Contingency  Plans.  The Company  believes it should not rely completely on
key vendor  compliance  certification.  Therefore  costs are being  incurred  to
enable the Company to utilize  alternative  design procedures to allow alternate
vendor supply.  These design changes are on-going and the costs are not expected
to be material.

     Risks.  The Company  presently does not  anticipate  any material  business
disruption  will occur as a result of Year 2000 issues.  The greatest  potential
risk appears to be with federal, state and local governments.

Exchange  Commission  in the United  States  District  Court for the District of

Injunction  and Other  Relief,  among  other  things,  that the  Company and Mr.
Gosselin committed  numerous  violations of the federal securities laws in 1989,
1990  and  1991,  including   disseminating   materially  false  and  misleading
information   about  the  Company  to  the  investing   public   through  public
announcements  and  filings  with the  Commission  relating,  primarily,  to the
Company's  acquisition  and  subsequent   disposition  of  two  companies,   Air
Instruments  and  Measurements,  Inc.  and  Environmental  Information  Systems.
Additionally,  the  Complaint  alleged that the Company's  financial  statements
incorrectly  reported  inventory figures and failed to reflect timely write-offs
of uncollectible accounts receivable and that the Company materially understated
annual and quarterly  losses  during this period.  The  allegations  against Ms.
Gosselin were that she served as the Company's Chief Financial  Officer and that
she was responsible for the Company's  inadequate books and records and internal
controls  during this  period.  The  Commission  also  alleged  that the Company
violated the federal  securities laws in connection with an unregistered  public
distribution of securities.  The Commission sought to enjoin the defendants from
engaging  in the  future in  similar  illegal  acts and  practices  and to order
defendant Albert E. Gosselin, Jr., to pay civil penalties. On July 14, 1994, the
defendants,  without  admitting  or  denying  any  of  the  allegations  of  the
Complaint,  consented to the entry of Final Judgment of Permanent Injunction and
Other  Relief  (the "Final  Judgment").  The Final  Judgment as to Mr.  Gosselin
required him to pay a civil penalty in the amount of $25,000.

to participate in the Company's Employee's Incentive Stock Option Plan and Group

through 2003 and annual  increases in the  discretion of the Board of Directors.
Pursuant to the employment agreements, they are required to be reimbursed by the

                          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, 1998,  and the
related   consolidated   statements  of  operations  and   comprehensive   loss,
stockholders'  equity and cash flows for the years ended  December  31, 1998 and
1997.  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, 1998, and the consolidated
results of their  operations  and their cash flows for the years ended  December
31, 1998 and 1997 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, 1998 AND 1997
                 ----------------------------------------------

NOTE 1 - BUSINESS ACTIVITY AND MANAGEMENT'S PLANS

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. also 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 April 1998 and February 1998, respectively
(Note 9).

In 1998,  Dasibi was awarded a $5.2  million  contract to install an eleven city
air monitoring  network in the Peoples  Republic of China.  Dasibi's  ability to
perform  under the terms of the  agreement  between  Dasibi  and China  National
Technical  Import  and  Export  Corporation  and  China  Green  Enterprises,  is
contingent  upon  Dasibi  obtaining  working  capital  to  finance  the  cost of
equipment,  training  and  contingencies.  Management  is  currently  working on
securing the working capital  financing,  which is expected to close in the near
future.

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 or market. Cost is determined on the
first-in first-out (FIFO) basis.

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 $79,427 and
$190,047 for the years ended December 31, 1998 and 1997, respectively.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Goodwill
- --------
Goodwill had been  previously  recorded in connection  with the  acquisition  of
Logan Medical  Devices,  Inc. and was being amortized on a  straight-line  basis
over 40 years.  Amortization  of goodwill was $7,003 for the year ended December
31,  1997.  The  goodwill  was  eliminated  upon the  discontinuance  of Logan's
operation (Note 9).

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 13 and 14 for  additional  information  with
respect to stock-based compensation.

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.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Investments in Equity Securities
- --------------------------------
Management  determines  the  appropriate  classification  of its  investments in
equity securities at the time of purchase and reevaluates such determinations at
each balance sheet date. The Company has classified its investment  portfolio as
available  for sale.  Available  for sale  securities  are stated at fair market
value with  unrealized  gains and losses  included  as a separate  component  of
stockholders' equity. Realized gains and losses are included in earnings and are
derived using the specific identification method.

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.

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.  A valuation  allowance has
been  established for the entire deferred tax asset as management  believes that
it is more likely than not that a tax benefit will not be realized.

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.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Reclassification
- ----------------
Certain  amounts  reported in the Company's  financial  statements  for the year
ended  December 31, 1997 have been  reclassified  to conform to the current year
presentation.

Comprehensive Income
- --------------------
In 1998, the Company  adopted FASB Statement No. 130,  "Reporting  Comprehensive
Income". This statement establishes rules for reporting comprehensive income and
its  components,  which  include net income and all other  changes in net assets
from non-owner  sources.  The Company has changed the format of its statement of
operations to present  comprehensive  income,  and has restated prior periods to
conform to the standard.

Segment Reporting
- -----------------
In 1997, the Company adopted FASB Statement No. 131,  Disclosures About Segments
of An Enterprise and Related  Information.  Information  regarding the Company's
reportable segments are disclosed in footnote 18.

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.

Using internal staff and outside consultants, the Company is actively addressing
this situation and  anticipates  that it will not experience a material  adverse
impact to its operations,  liquidity or financial  condition  related to systems
under its control.  The Company has  addressed the Year 2000 issue by purchasing
and installing Year 2000 compatible  software and computers,  assessing critical
business  relationships  requiring  modification  prior to 2000  and  developing
contingency  and business  continuation  plans to mitigate any disruption of the
Company's operations arising from the Year 2000 issue.

The Company is in the process of implementing a plan to obtain  information from
its  external  service  providers,  significant  suppliers  and  customers,  and
financial  institutions to confirm their plans and readiness to become Year 2000
compliant, in order to better understand and evaluate how their Year 2000 issues
may affect the Company's operations.  The Company currently is not in a position
to assess this aspect of the Year 2000 issue, however, the Company plans to take
the necessary steps to provide itself with reasonable assurance that its service
providers,  suppliers,  customers  and  financial  institutions  are  Year  2000
compliant.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

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.

NOTE 8 - 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, 1998  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
$58,135 as long term, respectively.

NOTE 9 - DISCONTINUED OPERATIONS

Nutek -
In April 1998, Nutek filed for protection under the Federal  Bankruptcy Code. In
June  1998,  as a  result  of  the  major  secured  lender's  opposition  to the
Bankruptcy  Code's  automatic  stay, 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,  based upon the major  secured
lenders assertion that the assets of Nutek were insufficient to cover the amount
of the secured  obligation.  The  assertion was supported by an appraisal of the
assets,  which differed  significantly from the original appraisal obtained upon
the purchase of Nutek in 1996. Management believes that there is the possibility
of questionable  activities in the 1996 purchase of Nutek and the financing with
the secured lender and appraisal obtained and utilized, and is investigating the
role of all parties involved in the acquisition and financing. Additionally, the
unsecured notes payable to Nutek's former stockholders and to a family member of
an  employee  were not  repaid.  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.

Summarized results of operations for Nutek for the years ended December 31, 1998
and 1997 are as follows:

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

NOTE 14 - 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 a charge to  operations  of $54,977 in 1998.
Additionally,  $24,790 was  capitalized as offering costs in connection with the
private placement.

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.

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.

NOTE 15 - COMMITMENTS AND CONTINGENCIES

Operating Leases
- ----------------
The Company  leases its  facilities  under  long-term  non-cancelable  operating
leases.  The lease terms provide for increases in future minimum rental payments
based on the Consumer  Price Index,  and an option to purchase  during the lease
term. Future minimum lease commitments as of December 31, 1998 are as follows:

Contingencies
- -------------
In connection  with the  discontinued  operations and bankruptcy  proceedings of
Nutek as  discussed  in Note 9, the  Company is party to a lawsuit  filed by the
major secured lender. The Company has accrued a settlement loss of approximately
$350,000 as the probable  outcome of this lawsuit.  The original claim filed was
approximately  $800,000,  however,  management does not feel the lawsuit will be
settled for this amount.

The Company has filed a breach of contract  lawsuit.  The complaint alleges that
the defendant  breached an agreement to purchase the Company's two subsidiaries.
The  Complaint  alleges  that  the  defendants  actions  constituted  breach  of
contract,  a breach of the covenant of good faith and fair dealing,  intentional
interference with prospective business advantage and negligent interference with
prospective  business  advantage.  The  Complaint  seeks  compensatory  damages,
punitive  damages and  declaratory  relief.  In July 1998 the  Company  borrowed
$101,000  from  the  defendant  Company  at  13%  interest.  Due  to  the  legal
proceedings  above, the Company has written off the note payable to other income
since it is probable that the funds will not be repaid upon settlement.

NOTE 16 - RELATED PARTY TRANSACTIONS

Prior to the disposal of LRL, the Company advanced  $203,938 to this subsidiary.
These  advances  are  expected  to be repaid from a joint  venture  relationship
between the Company and LRL.

In July  1998,  PIC  agreed to lease  back the Tech  Center for a period of five

China. Fees for PIC services will be negotiated on a project by project basis.

NOTE 19 - CONCENTRATION OF CREDIT RISK

Concentrations  of credit risk with  respect to trade  receivables  exist due to
large balances with a few customers.  At December 31, 1998,  accounts receivable
balances from three  significant  customers were  $158,019,  or 71% of the total
accounts  receivable  balance.  Substantially  all  of  the  Company's  domestic
receivables  at  December  31,  1998 are  factored  (Note  11).  Ongoing  credit
evaluations  of customers'  financial  conditions are performed and generally no
collateral is required.  The Company  maintains  reserves for  potential  credit
losses,  and  such  losses  in the  aggregate  have  not  exceeded  management's
expectations. Customers are located throughout the world.

The  Company  maintains  all cash in bank  accounts,  which at times may  exceed
federally insured limits.

                                      E-19



                                 EXHIBIT 10.154
                               PURCHASE AGREEMENT
                      POLLUTION RESEARCH AND CONTROL CORP.

     THIS PURCHASE AGREEMENT  ("Agreement" herein) is entered into as of the 8th
day of May,  1998 between  POLLUTION  RESEARCH AND CONTROL  CORP.,  a California
corporation with its principal offices at 506 Paula Avenue, Glendale, California
91201 (the  "Company")  and Albert E.  Gosselin,  Jr. whose address is 506 Paula
Avenue, Glendale, Ca 91201 (the "Purchaser").

     WHEREAS,  the Company  elects to issue and sell its  Preferred  Convertible
Stock (the  "Shares")  and the  Purchaser  desires  to acquire  the Shares for a
purchase  price of $.125  cents per  share.  This new issue of shares has voting
rights but no dividend rights and is convertible anytime after July 30, 1998.*

     NOW,   THEREFORE,   for  and  in  consideration  of  the  mutual  covenants
hereinafter set forth, the parties hereto do hereby agree as follows:

     I. PURCHASE OF SHARES AND REPRESENTATIONS BY SUBSCRIBER.

     1.1  Subject  to the  terms  and  conditions  hereinafter  set  forth,  the
Purchaser  hereby  purchases  400,000  Shares and the Company agrees to sell the
Shares to the Purchaser for a purchase  price of $50,000.  The purchase price is
payable by a cashier's check made payable to the Company, or by wire transfer to
an account  determined by the Company  contemporaneously  with the execution and
delivery of this  Agreement.  The Shares will be delivered by the Company to the
Purchaser within ten (10) days following the execution of the Agreement.

     1.2 The  Purchaser  recognizes  that the purchase of the Shares  involves a
high degree of risk in that an investment  in the company is highly  speculative
and only an investor who can afford to lose its entire investment in the Company
should purchase the Shares.

     1.3 The Purchaser acknowledges that he is able to bear the economic risk of
this investment.

     1.4 The Purchaser  represents that he is an "accredited  investor," as such
term is defined in Rule 501 of Regulation D promulgated under the Securities Act
of 1933, as amended (the "Act").

     1.5 The Purchaser  acknowledges  that he has prior  investment  experience,
including  investment in non-listed  and  non-registered  securities,  or he has
employed the services of an investment  advisor,  attorney or accountant to read
all of the  documents  furnished or made  available by the Company to him and to
evaluate the merits and risks of such an investment on his behalf.

     1.6 The  Purchaser  hereby  represents  that he has been  furnished  by the
Company during the course of this transaction with all information regarding the
Company  which he had  requested or desired to know;  that all  documents  which


                                      E-20

<PAGE>


could be reasonably  provided have been made  available for his  inspection  and
review;  that he has been  afforded  the  opportunity  to ask  questions  of and
receive answers from duly authorized  officers or other  representatives  of the
Company  concerning  the terms and  conditions of his investment in the Company,
and any additional information which he had requested.

     1.7 The  Purchaser  hereby  acknowledges  that this  offering  has not been
reviewed by the Securities and Exchange Commission (the "Commission") since this
offering is intended to be a  non-public  offering  pursuant to Section 4 (2) of
the Act. The Purchaser  represents  that the Shares are being  purchased for his
own account,  for investment,  and not for distribution or resale to others. The
Purchaser  agrees that he will not sell or otherwise  transfer  such  securities
unless  they are  registered  under  the Act or unless  an  exemption  from such
registration is available.

     1.8 The  Purchaser  understands  that the Shares  have not been  registered
under the Act by reason of a claimed  exemption  under the provisions of the Act
which depends, in part, upon its investment intention.  In this connection,  the
Purchaser  understands  that  it is the  position  of the  Commission  that  the
statutory basis for such exemption  would not be present if his  representations
merely meant that its present  intention was to hold such securities for a short
period, for a deferred sale, for a market rise, assuming that a market develops,
or for any other fixed period.  The Purchaser  realizes that, in the view of the
Commission,  a purchase now with an intent to resell would  represent a purchase
with an intent  inconsistent  with his  representation  to the Company,  and the
Commission  might regard such a sale or  disposition as a deferred sale to which
the exemption is not available.

     1.9 The Purchaser consents that the Company may, if he desires,  permit the
transfer  of the Shares out of his name only when his  request  for  transfer is
accompanied by an opinion of council reasonably satisfactory to the Company that
neither the sale nor the proposed  transfer results in a violation of the Act or
any applicable state "blue sky" laws (collectively,  the "Securities Laws"). The
Purchaser  agrees to hold the Company,  its directors,  officers and controlling
persons and their  respective  heirs,  representatives,  successors  and assigns
harmless  and to  indemnify  them  against all  liabilities,  costs and expenses
incurred  by them as a result  of any  misrepresentation  made by him  contained
herein or in the Confidential  Purchaser  Questionnaire  completed by him or any
sale or distribution by the Purchaser in violation of any Securities Laws.

     1.10 The Purchaser consents to the placement of a legend on any certificate
or  other  document  evidencing  the  Shares  stating  that  they  have not been
registered  under the Act and setting forth or referring to the  restrictions on
transferability  and sale thereof.  The Purchaser is aware that the Company will
make a notation in its appropriate  records with respect to the  restrictions on
the transferability of such securities.


     II. REPRESENTATIONS BY, AND COVENANTS OF, THE COMPANY.

     The Company represents and covenants to the Purchaser that:

     (a) The  Company is a  corporation  duly  organized,  existing  and in good
standing under the laws of the State of California which has the corporate power

     (b) The  execution,  delivery  and  performance  of this  Agreement  by the
Company has been duly  approved by the Board of Directors of the Company and all
other actions  required to authorize and effect the offer and sale of the Shares
have been duly taken and approved.

     (c) The Shares have been duly and validly  authorized  and, when issued and
paid  for  in  accordance  with  the  terms  hereof,  will  be  validly  binding
obligations of the Company enforceable in accordance with their respective terms
except that the enforceability thereof may be limited by bankruptcy, insolvency,
or other  laws  affecting  the  rights  of  creditors  generally  or by  general
equitable principles.

     (d) The Company has obtained all licenses,  permits and other  governmental
authorizations necessary to the conduct of its business; such licenses,  permits
and other governmental authorizations obtained are in full force and effect; and
the Company is in all material respects complying therewith.

     III. REGISTRATION OF SECURITIES.

     The Company  acknowledges  that it currently has no effective  registration
statement on Form S-3 on file with the Securities and Exchange Commission.

                               PURCHASE AGREEMENT
                      POLLUTION RESEARCH AND CONTROL CORP.

     THIS PURCHASE AGREEMENT  ("Agreement" herein) is entered into as of the 8th
day of May,  1998 between  POLLUTION  RESEARCH AND CONTROL  CORP.,  a California
corporation with its principal offices at 506 Paula Avenue, Glendale, California
91201 (the  "Company")  and Patricia Cudd whose address is 1120 Lincoln  Street,
#703, Denver, Co 80203 (the "Purchaser").

     WHEREAS,  the Company  elects to issue and sell its  Preferred  Convertible
Stock (the  "Shares")  and the  Purchaser  desires  to acquire  the Shares for a
purchase  price of $.125  cents per  share.  This new issue of shares has voting
rights but no dividend rights and is convertible anytime after July 30, 1998.*

     NOW,   THEREFORE,   for  and  in  consideration  of  the  mutual  covenants
hereinafter set forth, the parties hereto do hereby agree as follows:

     I. PURCHASE OF SHARES AND REPRESENTATIONS BY SUBSCRIBER.

     1.1  Subject  to the  terms  and  conditions  hereinafter  set  forth,  the
Purchaser  hereby  purchases  400,000  Shares and the Company agrees to sell the
Shares to the Purchaser for a purchase  price of $50,000.  The purchase price is
payable by a cashier's check made payable to the Company, or by wire transfer to
an account  determined by the Company  contemporaneously  with the execution and
delivery of this  Agreement.  The Shares will be delivered by the Company to the
Purchaser within ten (10) days following the execution of the Agreement.

     1.2 The  Purchaser  recognizes  that the purchase of the Shares  involves a
high degree of risk in that an investment  in the company is highly  speculative
and only an investor who can afford to lose its entire investment in the Company
should purchase the Shares.

     1.3 The Purchaser  acknowledges  that she is able to bear the economic risk
of this investment.

     1.4 The Purchaser represents that she is an "accredited  investor," as such
term is defined in Rule 501 of Regulation D promulgated under the Securities Act
of 1933, as amended (the "Act").

     1.5 The Purchaser  acknowledges  that she has prior investment  experience,
including  investment in non-listed and  non-registered  securities,  or she has
employed the services of an investment  advisor,  attorney or accountant to read
all of the  documents  furnished or made  available by the Company to her and to
evaluate the merits and risks of such an investment on her behalf.

     1.6 The  Purchaser  hereby  represents  that she has been  furnished by the
Company during the course of this transaction with all information regarding the
Company  which she had requested or desired to know;  that all  documents  which
could be reasonably  provided have been made  available for his  inspection  and


                                      E-24

<PAGE>


review;  that she has been  afforded  the  opportunity  to ask  questions of and
receive answers from duly authorized  officers or other  representatives  of the
Company  concerning  the terms and  conditions of his investment in the Company,
and any additional information which she had requested.

     1.7 The  Purchaser  hereby  acknowledges  that this  offering  has not been
reviewed by the Securities and Exchange Commission (the "Commission") since this
offering is intended to be a  non-public  offering  pursuant to Section 4 (2) of
the Act. The Purchaser  represents  that the Shares are being  purchased for her
own account,  for investment,  and not for distribution or resale to others. The
Purchaser  agrees that she will not sell or otherwise  transfer such  securities
unless  they are  registered  under  the Act or unless  an  exemption  from such
registration is available.

     1.8 The  Purchaser  understands  that the Shares  have not been  registered
under the Act by reason of a claimed  exemption  under the provisions of the Act
which depends, in part, upon its investment intention.  In this connection,  the
Purchaser  understands  that  it is the  position  of the  Commission  that  the
statutory basis for such exemption  would not be present if her  representations
merely meant that its present  intention was to hold such securities for a short
period, for a deferred sale, for a market rise, assuming that a market develops,
or for any other fixed period.  The Purchaser  realizes that, in the view of the
Commission,  a purchase now with an intent to resell would  represent a purchase
with an intent  inconsistent  with her  representation  to the Company,  and the
Commission  might regard such a sale or  disposition as a deferred sale to which
the exemption is not available.

     1.9 The Purchaser consents that the Company may, if she desires, permit the
transfer  of the Shares out of her name only when her  request  for  transfer is
accompanied by an opinion of council reasonably satisfactory to the Company that
neither the sale nor the proposed  transfer results in a violation of the Act or
any applicable state "blue sky" laws (collectively,  the "Securities Laws"). The
Purchaser  agrees to hold the Company,  its directors,  officers and controlling
persons and their  respective  heirs,  representatives,  successors  and assigns
harmless  and to  indemnify  them  against all  liabilities,  costs and expenses
incurred  by them as a result  of any  misrepresentation  made by him  contained
herein or in the Confidential  Purchaser  Questionnaire  completed by him or any
sale or distribution by the Purchaser in violation of any Securities Laws.

     1.10 The Purchaser consents to the placement of a legend on any certificate
or  other  document  evidencing  the  Shares  stating  that  they  have not been
registered  under the Act and setting forth or referring to the  restrictions on
transferability  and sale thereof.  The Purchaser is aware that the Company will
make a notation in its appropriate  records with respect to the  restrictions on
the transferability of such securities.


     II. REPRESENTATIONS BY, AND COVENANTS OF, THE COMPANY.

     The Company represents and covenants to the Purchaser that:

     (a) The  Company is a  corporation  duly  organized,  existing  and in good
standing under the laws of the State of California which has the corporate power
to conduct the business which it conducts and proposes to conduct.


                                      E-25

     (b) The  execution,  delivery  and  performance  of this  Agreement  by the
Company has been duly  approved by the Board of Directors of the Company and all
other actions  required to authorize and effect the offer and sale of the Shares
have been duly taken and approved.

     (c) The Shares have been duly and validly  authorized  and, when issued and
paid  for  in  accordance  with  the  terms  hereof,  will  be  validly  binding
obligations of the Company enforceable in accordance with their respective terms
except that the enforceability thereof may be limited by bankruptcy, insolvency,
or other  laws  affecting  the  rights  of  creditors  generally  or by  general
equitable principles.

     (d) The Company has obtained all licenses,  permits and other  governmental
authorizations necessary to the conduct of its business; such licenses,  permits
and other governmental authorizations obtained are in full force and effect; and
the Company is in all material respects complying therewith.

     III. REGISTRATION OF SECURITIES.

     The Company  acknowledges  that it currently has no effective  registration
statement on Form S-3 on file with the Securities and Exchange Commission.

     IV. MISCELLANEOUS.

     4.1 Any  notice  or other  communication  given  hereunder  shall be deemed
sufficient  if in writing  and sent by  registered  or  certified  mail,  return

address  listed on the  signature  page hereof.  Notices shall be deemed to have
been given on the date of mailing,  except  notices of change of address,  which
shall be deemed to have been given when received.

     4.2 This  Agreement  shall not be  changed,  modified  or made  except by a
writing  signed by the  parties to be  charged,  and this  Agreement  may not be
discharged  except by performance  in accordance  with its terms or by a writing
signed by the party to be charged.

     4.3 This  Agreement  shall be binding  upon and inure to the benefit of the
parties hereto and to their respective heirs, legal representatives,  successors
and assigns.  This Agreement sets forth the entire  agreement and  understanding
between the parties as to the subject  matter  hereof and merges and  supersedes
all prior  discussions,  agreements and  understandings  of any and every nature
among them.

     4.4 This Agreement and its validity,  construction and performance shall be
governed in all respects by the laws of the State of California,  without regard
to principles of conflicts of law.

Pollution Research and Control Corp.
506 Paula Avenue
Glendale, California 91201

Gentlemen:

     In connection  with the  acquisition by the undersigned of 20,000 shares of
common stock, no par value per share (the "Common Stock"),  at a per share price
of $1.09 (60% of the bid price per share of Common  Stock as of June 18,  1998),
of Pollution  Research and Control Corp. (the "Company"),  in consideration  for
the sum of  $21,800.00  in cash,  the  undersigned  wishes to advise  you of his
understanding of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph  4(1)  or  4(2)  of the  Act  and  the  Rules  and  Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

          The shares  represented  by this  certificate  have not been
          registered under the Securities Act of 1933 (the "Act"), and
          are  "restricted  securities" as the term is defined in Rule
          144 under the Act.  The shares may not be offered  for sale,
          sold  or  otherwise   transferred   except  pursuant  to  an
          effective  registration statement under the Act, or pursuant
          to  an  exemption  from  registration  under  the  Act,  the
          availability   of  which  is  to  be   established   to  the
          satisfaction of the Company.

     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.


                                      E-32

<PAGE>



     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act if  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation A under the Act and that the Company has no obligation to do so or to
take steps necessary to make Rule 144 available to him. The undersigned also has
been advised and acknowledges that he understands that, in the event Rule 144 is
not available, the circumstances under which he can sell the securities,  absent
registration or compliance with Regulation A, are extremely limited.

     The undersigned further  acknowledges and represents to the Company that he
is purchasing the securities for his own account and not as a trustee or nominee
for any other person or persons,  and that the funds or  consideration  invested
are his own. The undersigned further  acknowledges and represents that there are
no  existing  legal  restrictions  applicable  to him which would  preclude  his
acquisition of the securities for investment purposes, as described hereinabove.
The  undersigned  further  represents that he has no present plans to enter into
any contract,  undertaking,  agreement or arrangement for resale,  distribution,
subdivision or fractionalization of the securities purchased hereby.

     The undersigned further acknowledges that he understands that an investment
in the Company is extremely speculative and subject to a high degree of risk. In

the value of the  assets or net worth of the  Company or any other  criteria  of
value.  The  undersigned is aware that no  independent  evaluation has been made

is knowledgeable and experienced in venture capital  investments in general and,
in particular, with respect to investments similar in nature to an investment in

Pollution Research and Control Corp.
506 Paula Avenue
Glendale, California 91201

Gentlemen:

     In connection  with the  acquisition by the undersigned of 23,190 shares of
common stock, no par value per share (the "Common Stock"),  at a per share price
of $1.09 (60% of the bid price per share of Common  Stock as of June 18,  1998),
of Pollution  Research and Control Corp. (the "Company"),  in consideration  for
the sum of  $25,277.10  in cash,  the  undersigned  wishes to advise  you of his
understanding of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph  4(1)  or  4(2)  of the  Act  and  the  Rules  and  Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

          The shares  represented  by this  certificate  have not been
          registered under the Securities Act of 1933 (the "Act"), and
          are  "restricted  securities" as the term is defined in Rule
          144 under the Act.  The shares may not be offered  for sale,
          sold  or  otherwise   transferred   except  pursuant  to  an
          effective  registration statement under the Act, or pursuant
          to  an  exemption  from  registration  under  the  Act,  the
          availability   of  which  is  to  be   established   to  the
          satisfaction of the Company.

     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.


                                      E-37

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act if  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation A under the Act and that the Company has no obligation to do so or to
take steps necessary to make Rule 144 available to him. The undersigned also has
been advised and acknowledges that he understands that, in the event Rule 144 is
not available, the circumstances under which he can sell the securities,  absent
registration or compliance with Regulation A, are extremely limited.

     The undersigned further  acknowledges and represents to the Company that he
is purchasing the securities for his own account and not as a trustee or nominee
for any other person or persons,  and that the funds or  consideration  invested
are his own. The undersigned further  acknowledges and represents that there are
no  existing  legal  restrictions  applicable  to him which would  preclude  his
acquisition of the securities for investment purposes, as described hereinabove.
The  undersigned  further  represents that he has no present plans to enter into
any contract,  undertaking,  agreement or arrangement for resale,  distribution,
subdivision or fractionalization of the securities purchased hereby.

     The undersigned further acknowledges that he understands that an investment
in the Company is extremely speculative and subject to a high degree of risk. In
this  connection,  the  undersigned  understands  that he may  lose  his  entire
investment in the Company.

     The undersigned further  acknowledges and represents to the Company that he
is able  to  bear  the  economic  risk of  losing  his  entire  investment.  The
undersigned  further  acknowledges  and warrants that his overall  commitment to

worth  and  his  investment  in the  securities  will  not  cause  such  overall
commitment to become excessive.  The undersigned  further represents that he has
adequate means of providing for his current needs and personal contingencies and
that he has no need for  liquidity  in  connection  with his  investment  in the
securities.

that the  price of the  Company's  securities  acquired  by him was  arbitrarily
determined  without  regard  to any  value of the  securities.  The  undersigned
understands, additionally, that the price of the securities bears no relation to
the value of the  assets or net worth of the  Company or any other  criteria  of
value.  The  undersigned is aware that no  independent  evaluation has been made

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144

Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation A under the Act and that the Company has no obligation to do so or to
take steps necessary to make Rule 144 available to him. The undersigned also has

subdivision or fractionalization of the securities purchased hereby.

investment in the Company.

is able  to  bear  the  economic  risk of  losing  his  entire  investment.  The

worth  and  his  investment  in the  securities  will  not  cause  such  overall
commitment to become excessive.  The undersigned  further represents that he has
adequate means of providing for his current needs and personal contingencies and
that he has no need for  liquidity  in  connection  with his  investment  in the
securities.

     The undersigned  further  acknowledges that he fully understands and agrees
that the  price of the  Company's  securities  acquired  by him was  arbitrarily
determined  without  regard  to any  value of the  securities.  The  undersigned
understands, additionally, that the price of the securities bears no relation to
the value of the  assets or net worth of the  Company or any other  criteria  of
value.  The  undersigned is aware that no  independent  evaluation has been made
with respect to the value of the securities. The undersigned further understands

the future be issued to certain other persons for a  consideration  which may be

is knowledgeable and experienced in venture capital  investments in general and,
in particular, with respect to investments similar in nature to an investment in
the Company.  The frequency of the  undersigned's  prior  investments  in stocks

Gentlemen:

     In connection  with the  acquisition by the undersigned of 20,000 shares of
common stock, no par value per share (the "Common Stock"),  at a per share price
of $1.09 (60% of the bid price per share of Common  Stock as of June 18,  1998),
of Pollution  Research and Control Corp. (the "Company"),  in consideration  for
the sum of  $21,800.00  in cash,  the  undersigned  wishes to advise  you of his
understanding of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph  4(1)  or  4(2)  of the  Act  and  the  Rules  and  Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

          The shares  represented  by this  certificate  have not been
          registered under the Securities Act of 1933 (the "Act"), and
          are  "restricted  securities" as the term is defined in Rule
          144 under the Act.  The shares may not be offered  for sale,
          sold  or  otherwise   transferred   except  pursuant  to  an
          effective  registration statement under the Act, or pursuant
          to  an  exemption  from  registration  under  the  Act,  the
          availability   of  which  is  to  be   established   to  the
          satisfaction of the Company.

     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.

Pollution Research and Control Corp.
506 Paula Avenue
Glendale, California 91201

Gentlemen:

     In connection  with the  acquisition by the undersigned of 23,000 shares of
common stock, no par value per share (the "Common Stock"),  at a per share price
of $1.09 (60% of the bid price per share of Common  Stock as of June 18,  1998),
of Pollution  Research and Control Corp. (the "Company"),  in consideration  for
the sum of  $25,070.00  in cash,  the  undersigned  wishes to advise  you of his
understanding of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph  4(1)  or  4(2)  of the  Act  and  the  Rules  and  Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

          The shares  represented  by this  certificate  have not been
          registered under the Securities Act of 1933 (the "Act"), and
          are  "restricted  securities" as the term is defined in Rule
          144 under the Act.  The shares may not be offered  for sale,
          sold  or  otherwise   transferred   except  pursuant  to  an
          effective  registration statement under the Act, or pursuant
          to  an  exemption  from  registration  under  the  Act,  the
          availability   of  which  is  to  be   established   to  the
          satisfaction of the Company.

          The  undersigned  understands  that the above  legend on the
          certificates would limit their value,  including their value
          as collateral.


                                 E-52

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act if  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation A under the Act and that the Company has no obligation to do so or to
take steps necessary to make Rule 144 available to him. The undersigned also has
been advised and acknowledges that he understands that, in the event Rule 144 is
not available, the circumstances under which he can sell the securities,  absent
registration or compliance with Regulation A, are extremely limited.

     The undersigned further  acknowledges and represents to the Company that he
is purchasing the securities for his own account and not as a trustee or nominee
for any other person or persons,  and that the funds or  consideration  invested
are his own. The undersigned further  acknowledges and represents that there are
no  existing  legal  restrictions  applicable  to him which would  preclude  his
acquisition of the securities for investment purposes, as described hereinabove.
The  undersigned  further  represents that he has no present plans to enter into
any contract,  undertaking,  agreement or arrangement for resale,  distribution,
subdivision or fractionalization of the securities purchased hereby.

     The undersigned further acknowledges that he understands that an investment
in the Company is extremely speculative and subject to a high degree of risk. In
this  connection,  the  undersigned  understands  that he may  lose  his  entire
investment in the Company.

     The undersigned further  acknowledges and represents to the Company that he
is able  to  bear  the  economic  risk of  losing  his  entire  investment.  The
undersigned  further  acknowledges  and warrants that his overall  commitment to
investments which are not readily marketable is not  disproportionate to his net
worth  and  his  investment  in the  securities  will  not  cause  such  overall
commitment to become excessive.  The undersigned  further represents that he has
adequate means of providing for his current needs and personal contingencies and
that he has no need for  liquidity  in  connection  with his  investment  in the
securities.

     The undersigned  further  acknowledges that he fully understands and agrees
that the  price of the  Company's  securities  acquired  by him was  arbitrarily
determined  without  regard  to any  value of the  securities.  The  undersigned
understands, additionally, that the price of the securities bears no relation to
the value of the  assets or net worth of the  Company or any other  criteria  of
value.  The  undersigned is aware that no  independent  evaluation has been made
with respect to the value of the securities. The undersigned further understands

                                      E-53

<PAGE>



and agrees  that shares of the common  stock of the Company  have been or may in
the future be issued to certain other persons for a  consideration  which may be
less than the price paid by him for the securities.

     The undersigned further  acknowledges and represents to the Company that he
is knowledgeable and experienced in venture capital  investments in general and,
in particular, with respect to investments similar in nature to an investment in
the Company.  The frequency of the  undersigned's  prior  investments  in stocks
(including restricted stocks), in general, and in high technology companies,  in
particular, and other investments, of whatever kind, is as follows (check one in

     In connection  with the  acquisition by the  undersigned of 9,174 shares of

of Pollution  Research and Control Corp. (the "Company"),  in consideration  for
the sum of  $9,999.66  in cash,  the  undersigned  wishes to  advise  you of his
understanding of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,

under  Paragraph  4(1)  or  4(2)  of the  Act  and  the  Rules  and  Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own

          satisfaction of the Company.

     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.

Pollution Research and Control Corp.
506 Paula Avenue
Glendale, California 91201

Gentlemen:

     In connection  with the  acquisition by the  undersigned of 9,082 shares of
common stock, no par value per share (the "Common Stock"),  at a per share price
of $1.09 (60% of the bid price per share of Common  Stock as of June 18,  1998),
of Pollution  Research and Control Corp. (the "Company"),  in consideration  for
the sum of  $9,900.00  in cash,  the  undersigned  wishes to  advise  you of his
understanding of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph  4(1)  or  4(2)  of the  Act  and  the  Rules  and  Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

          The shares  represented  by this  certificate  have not been
          registered under the Securities Act of 1933 (the "Act"), and
          are  "restricted  securities" as the term is defined in Rule
          144 under the Act.  The shares may not be offered  for sale,
          sold  or  otherwise   transferred   except  pursuant  to  an
          effective  registration statement under the Act, or pursuant
          to  an  exemption  from  registration  under  the  Act,  the
          availability   of  which  is  to  be   established   to  the
          satisfaction of the Company.

     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.


                                      E-62

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act if  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation A under the Act and that the Company has no obligation to do so or to
take steps necessary to make Rule 144 available to him. The undersigned also has
been advised and acknowledges that he understands that, in the event Rule 144 is
not available, the circumstances under which he can sell the securities,  absent
registration or compliance with Regulation A, are extremely limited.

     The undersigned further  acknowledges and represents to the Company that he
is purchasing the securities for his own account and not as a trustee or nominee
for any other person or persons,  and that the funds or  consideration  invested
are his own. The undersigned further  acknowledges and represents that there are
no  existing  legal  restrictions  applicable  to him which would  preclude  his
acquisition of the securities for investment purposes, as described hereinabove.
The  undersigned  further  represents that he has no present plans to enter into
any contract,  undertaking,  agreement or arrangement for resale,  distribution,
subdivision or fractionalization of the securities purchased hereby.

     The undersigned further acknowledges that he understands that an investment
in the Company is extremely speculative and subject to a high degree of risk. In
this  connection,  the  undersigned  understands  that he may  lose  his  entire
investment in the Company.

     The undersigned further  acknowledges and represents to the Company that he
is able  to  bear  the  economic  risk of  losing  his  entire  investment.  The
undersigned  further  acknowledges  and warrants that his overall  commitment to
investments which are not readily marketable is not  disproportionate to his net
worth  and  his  investment  in the  securities  will  not  cause  such  overall
commitment to become excessive.  The undersigned  further represents that he has
adequate means of providing for his current needs and personal contingencies and
that he has no need for  liquidity  in  connection  with his  investment  in the
securities.

     The undersigned  further  acknowledges that he fully understands and agrees
that the  price of the  Company's  securities  acquired  by him was  arbitrarily
determined  without  regard  to any  value of the  securities.  The  undersigned
understands, additionally, that the price of the securities bears no relation to
the value of the  assets or net worth of the  Company or any other  criteria  of
value.  The  undersigned is aware that no  independent  evaluation has been made
with respect to the value of the securities. The undersigned further understands

                                      E-63

and agrees  that shares of the common  stock of the Company  have been or may in
the future be issued to certain other persons for a  consideration  which may be
less than the price paid by him for the securities.

is knowledgeable and experienced in venture capital  investments in general and,
in particular, with respect to investments similar in nature to an investment in
the Company.  The frequency of the  undersigned's  prior  investments  in stocks
(including restricted stocks), in general, and in high technology companies,  in
particular, and other investments, of whatever kind, is as follows (check one in

experience  in financial  and business  matters that he is capable of evaluating

by the Company to consult with counsel  regarding this  investment;  and that he

Gentlemen:

     In connection  with the  acquisition by the undersigned of 18,000 shares of
common stock, no par value per share (the "Common Stock"),  at a per share price
of $1.09 (60% of the bid price per share of Common  Stock as of June 18,  1998),
of Pollution  Research and Control Corp. (the "Company"),  in consideration  for
the sum of  $19,260.00  in cash,  the  undersigned  wishes to advise  you of his
understanding of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph  4(1)  or  4(2)  of the  Act  and  the  Rules  and  Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

          The shares  represented  by this  certificate  have not been
          registered under the Securities Act of 1933 (the "Act"), and
          are  "restricted  securities" as the term is defined in Rule
          144 under the Act.  The shares may not be offered  for sale,
          sold  or  otherwise   transferred   except  pursuant  to  an
          effective  registration statement under the Act, or pursuant
          to  an  exemption  from  registration  under  the  Act,  the
          availability   of  which  is  to  be   established   to  the
          satisfaction of the Company.

     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.

     The  undersigned  further  acknowledges  that he  understands  that, if the

Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be

the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation A under the Act and that the Company has no obligation to do so or to
take steps necessary to make Rule 144 available to him. The undersigned also has
been advised and acknowledges that he understands that, in the event Rule 144 is
not available, the circumstances under which he can sell the securities,  absent
registration or compliance with Regulation A, are extremely limited.

acquisition of the securities for investment purposes, as described hereinabove.
The  undersigned  further  represents that he has no present plans to enter into
any contract,  undertaking,  agreement or arrangement for resale,  distribution,
subdivision or fractionalization of the securities purchased hereby.

     The undersigned further acknowledges that he understands that an investment
in the Company is extremely speculative and subject to a high degree of risk. In
this  connection,  the  undersigned  understands  that he may  lose  his  entire
investment in the Company.

     The undersigned further  acknowledges and represents to the Company that he
is able  to  bear  the  economic  risk of  losing  his  entire  investment.  The

                                OPTION AGREEMENT


     This Option Agreement (the  "Agreement") is made and entered into effective
as of June 19, 1998 by and between  Pollution  Research  and  Control  Corp.,  a
California corporation ("PRCC") and Phoenix Alliance, Inc. ("Optionee").

     WHEREAS,  PRCC is willing to grant  Optionee an option to purchase up to an

     NOW, THEREFORE, the parties agree as follows:

          (b) Neither the Option nor any Option Share shall be sold or otherwise
distributed in violation of the Act, the California Law or any other  applicable
federal or state securities law;

and he has no present  intention  of becoming a resident or  domiciliary  of any
other state of jurisdiction;
                          
          (h) In making the  decision to accept the Option  and/or  purchase the
Option Shares, he has relied solely upon independent  investigations  made by or
on behalf  of him;  (i) No  federal  or state  agency  has made any  finding  or
determination as to the fairness of an investment in PRCC; and

          (j) He understands that all the representations and warranties made by
him herein,  and all information  furnished by him to PRCC, is true, correct and

disbursements)  which  any of them may incur by  reason  of any  breach  and any
representation,   warranty,   covenant  or  agreement   contained  herein.   All
representations,  warranties,  covenants and agreements, and the indemnification
contained  herein shall  survive the grant of the Option and the issuance of the
Option Shares by PRCC.

Agreement  shall  be  subject  to the  provisions  of  this  Agreement  and  the
certificates  representing such Option Shares shall bear the following legend or

                                OPTION AGREEMENT


     This Option Agreement (the  "Agreement") is made and entered into effective
as of December 14, 1998 by and between  Pollution  Research and Control Corp., a
California corporation ("PRCC") and Cindy Gosselin ("Optionee").

     WHEREAS, Optionee has been providing valuable services as recognized by the
Company's  Board of  Directors  to PRCC and PRCC is desirous of having  Optionee
continue to provide such services to it; and

     WHEREAS,  PRCC is willing to grant  Optionee an option to purchase up to an
aggregate of 12,500 shares of the no par value common stock of PRCC (the "Common
Stock") under the terms and conditions set forth below.

     NOW, THEREFORE, the parties agree as follows:

     1. Grant of Option. PRCC hereby grants to Optionee, as a matter of separate
agreement  and not in lieu of other  compensation  for  services,  the right and
option (the  "Option") to purchase on the terms and conditions set forth in this
Agreement all or any part of up to an aggregate of 12,500 shares of Common Stock

     5. Securities Laws Requirements. The Option Shares have not been registered
under the Securities  Act of 1933, as amended (the "Act"),  and no Shares may be
sold, offered for sale, transferred, pledged, hypothecated or otherwise disposed
of except in compliance with the Act and any other applicable  federal and state
securities  laws.  Additionally,  the Option and the Option Shares have not been
qualified  under  the  California  Securities  Law  of  1968,  as  amended  (the

the Act or  qualify  the  Option  Shares  under  the  California  Law.  Optionee

public  resale  of  registered  securities  and  under  the terms of Rule 144 as
currently in effect,  the Shares  received by Optionee may be sold to the public
without  registration  only after a period of two (2) years has elapsed from the
exercise  date  of the  Option  and  then  only in  compliance  with  all  other
requirements of Rule 144 and the Act. Optionee hereby acknowledges,  represents,
warrants and agrees as follows:

          (a) That the Option and the Option Shares are not registered under the
Act or  qualified  under the  California  Law,  and the Option  Shares shall be,
acquired  solely for the account of Optionee for  investment  purposes  only and
with no view to their resale or other distribution of any kind;

          (b) Neither the Option nor any Option Share shall be sold or otherwise
distributed in violation of the Act, the California Law or any other  applicable
federal or state securities law;
                          
          (c) Her  overall  commitment  to  investments  that  are  not  readily
marketable is not  disproportionate to her net worth, and her investment in PRCC
will not cause such overall commitment to become excessive;
                         
          (d) She has the  financial  ability to bear the  economic  risk of her
investment,  has adequate  means of providing for her current needs and personal
contingencies, and has no need for liquidity in her investment in PRCC;

          (e)  She  either:   (i)  has  a   preexisting   personal  or  business
relationship  with PRCC or its officers,  directors or controlling  persons,  or
(ii) has evaluated the business of PRCC and the high risks of investing in PRCC,
the  competitive  nature of the  business in which PRCC is engaged,  and has the


                                      E-95

<PAGE>



business or financial  experience or has business or financial  advisors who are
unaffiliated  with,  and not  compensated  by, PRCC and protect her interests in
connection with the transaction;

          (f) She has been given the  opportunity  to review all books,  records
and  documents  of PRCC and to ask  questions  and  receive  answers  from  PRCC
concerning PRCC's business, to obtain additional information necessary to verify
the  accuracy  of the  information  she has  desired  in order to  evaluate  her
investment,  and to consult with such attorneys,  accountants and other advisors
as she has desired;

          (g) Her residence  set forth below is her true and correct  residence,
and she has no present  intention of becoming a resident or  domiciliary  of any
other state of jurisdiction;
                        
          (h) In making the  decision to accept the Option  and/or  purchase the
Option Shares, she has relied solely upon independent  investigations made by or
on behalf of him;

          (i) No federal or state  agency has made any finding or  determination
as to the fairness of an investment in PRCC; and

          (j) She understands that all the  representations  and warranties made
by him herein,  and all information  furnished by him to PRCC, is true,  correct
and complete in all respects.
              
     6. Optionee hereby  acknowledges that she understands the meaning and legal
consequences of the  representations,  warranties and covenants contained herein
and that PRCC has relied on the representations  made by Optionee in paragraph 5
hereof in granting  this  Option,  and  Optionee  agrees to  indemnify  and hold
harmless  PRCC and its  officers,  directors,  controlling  persons,  attorneys,
agents and  employees  from and against any and all loss,  damage or  liability,
together   with  all  costs  and  expenses   (including   attorneys'   fees  and
disbursements)  which  any of them may incur by  reason  of any  breach  and any
representation,   warranty,   covenant  or  agreement   contained  herein.   All
representations,  warranties,  covenants and agreements, and the indemnification
contained  herein shall  survive the grant of the Option and the issuance of the
Option  Shares by PRCC.

     7.  Legend of  Certificates.  All Option  Shares  issued  pursuant  to this
Agreement  shall  be  subject  to the  provisions  of  this  Agreement  and  the
certificates  representing such Option Shares shall bear the following legend or
language substantially equivalent thereto:

$100,000                                                    Glendale, California
                                                            January 27, 1999


     FOR VALUE RECEIVED, the undersigned,  Pollution Research and Control Corp.,
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 Mark S. Rose (hereinafter  referred to as the "Holder"),  at
72 West Avenue, Patchogue, New York 11772, or such other place as the Holder may
designate in writing, in coin or currency 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 one hundred thousand  dollars  ($100,000),  together
with interest  thereon at the rate of eleven per cent (11%) per annum,  from the
date hereof 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 May 27, 1999.

     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 pre-payment of accrued 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  interest,  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,  bringing of suit and
diligence  in taking any action to collect  amounts  called for  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.

                                      E-100

<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  on 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.

     2. Grant of Option.  Subject to the terms and conditions of this Agreement,
the Company  hereby grants to the Optionee the right to purchase all or any part
of an aggregate of 48,000  shares of Common Stock of the Company at the Purchase
Price set forth in  Section 3 hereof and in  accordance  with the  schedule  set
forth in Section 5 hereof. This right to purchase Shares is hereinafter referred
to as the "Option."

     3. Purchase Price.  The purchase price of the shares of Common Stock of the
Company issuable pursuant to the exercise of this Option shall be $.75 per Share
(the "Purchase Price.")

     4. Term of Option.  Notwithstanding  anything to the contrary  contained in
this  Agreement,  no option granted  hereunder  shall be  exercisable  after the
expiration of the Expiration Date.

     5. Exercise.

          (a) Time of Exercise.  This Option may be exercised  commencing on the
Effective  Date,  in whole or in part (but not as to a fractional  share) at the
principal  executive  offices of the Company,  at any time or from time to time,
through and  including  January 27, 2002;  provided,  however,  that this Option
shall expire and be null and void if not exercised in the manner herein provided
by 5:00 p.m., Pacific Standard Time, on January 27, 2002.

          (b) Manner of  Exercise.  This Option is  exercisable  at the Purchase
Price,  payable  in cash or by  cashier's  check  payable  to the  order  of the
Company,  subject to adjustment as provided in Section 6 hereof.  Upon surrender
of this  Option to the  Company  at its  principal  executive  offices  with the
annexed  Subscription  and  Acknowledgment  Form duly  executed,  together  with
payment of the  Purchase  Price for the  Shares  purchased  (and any  applicable
transfer taxes) at the Company's principal executive offices, the Optionee shall
be  entitled  to  receive  a  certificate  or  certificates  for the  Shares  so
purchased.  The Optionee hereby acknowledges and agrees to the taxable nature of
the event of the exercise of the Option and that the Optionee  will not hold the
Company responsible for the reporting or payment of such taxes.

          (c) Delivery of Stock  Certificates.  As soon as practicable,  but not
exceeding  five days after  complete  or partial  exercise of this  Option,  the
Company,  at its  expense,  shall cause to be issued in the name of the Optionee
(or  upon  payment  by  the  Optionee  of any  applicable  transfer  taxes,  the
Optionee's  assigns) a certificate or certificates  for the number of fully-paid
and  nonassessable  Shares to which the  Optionee  shall be  entitled  upon such
exercise,   together  with  such  other  stock  or  securities  or  property  or
combination  thereof to which the Optionee shall be entitled upon such exercise,
determined in accordance with Section 6 hereof.

          (d) Record  Date of Transfer  of Shares.  Irrespective  of the date of
issuance and delivery of certificates for any stock or securities  issuable upon
the  exercise  of  this  Option,   each  person   (including  a  corporation  or


                                      E-103

<PAGE>


partnership)  in whose name any such  certificate  is to be issued shall for all
purposes  be  deemed  to have  become  the owner of record of the stock or other
securities represented thereby immediately prior to the close of business on the
date on which a duly executed Subscription Form containing notice of exercise of
this Option and payment of the Purchase Price is received by the Company.

     6. Adjustment of Purchase Price.

     The Purchase Price shall be subject to adjustment as follows:

          (a) In case the  Company  shall  (i) pay a  dividend  in shares of its
capital  stock (other than an issuance of shares of capital  stock to holders of
Common  Stock who have elected to receive a dividend in shares in lieu of cash),
(ii) subdivide its outstanding shares of Common Stock, (iii) reduce, consolidate
or combine  its  outstanding  shares of Common  Stock  into a smaller  number of
shares or (iv)  issue by  reclassification  of its  shares  of Common  Stock any
shares of the Company,  the Purchase Price in effect  immediately  prior thereto
shall be adjusted to that amount determined by multiplying the Purchase Price in
effect  immediately  prior to such date by a  fraction,  of which the  numerator
shall be the number of shares of Common  Stock  outstanding  on such date before
giving   effect  to  such   division,   subdivision,   reduction,   combination,
consolidation or stock dividend and of which the denominator shall be the number
of shares of Common Stock after giving effect thereto.  Such adjustment shall be
made  successively  whenever any such effective date or record date shall occur.
An  adjustment  made  pursuant to this  subsection  (a) shall  become  effective
retroactively  to the Effective  Date  immediately  after the record date in the
case of a dividend and shall become  effective  immediately  after the effective
date in the case of a  subdivision,  reduction,  consolidation,  combination  or
reclassification.

          (b) In case the  Company  shall  issue  rights  or  options  to all or
substantially  all  holders of its  Common  Stock  entitling  them (for a period
expiring within 45 days after the record date mentioned  below) to subscribe for
or purchase shares of Common Stock (or securities convertible into Common Stock)
at a price per share (the "Offering  Price") less than the Purchase Price at the
record date mentioned  below, the Purchase Price shall be determined by dividing
the Purchase Price in effect immediately prior to such issuance by a fraction of
which the numerator shall be the number of shares of Common Stock outstanding on
the date of  issuance of such  rights or options  plus the number of  additional
shares of Common Stock offered for  subscription  or purchase,  and of which the
denominator  shall be the number of shares of Common  Stock  outstanding  on the
date of issuance of such rights or options  plus the number of shares  which the
aggregate Offering Price of the total number of shares so offered would purchase
at such fair market value. Such adjustment shall be made whenever such rights or
options are issued, and shall become effective retroactively,  immediately after
the record date for the  determination of shareholders  entitled to receive such
rights or options.

          (c) In case the Company shall distribute to all or  substantially  all
holders of its Common Stock evidence of its indebtedness, shares of any class of
the Company's stock other than Common Stock or assets (excluding cash dividends)
or rights or options to  subscribe  for or  purchase  shares of Common  Stock or


                                      E-104

<PAGE>


securities  convertible  into  Common  Stock  (excluding  those  referred  to in
subsection  (b)  above),  then in each such  case the  Purchase  Price  shall be
determined by dividing the Purchase  Price in effect  immediately  prior to such
issuance by a fraction,  of which the numerator  shall be the Purchase  Price on
the date of such  distribution  and of which the denominator  shall be such fair
market value per share of the Common Stock,  less the then fair market value (as
determined  by the  Committee,  whose  determination  shall be  conclusive,  and
described  in a statement,  which will have the  applicable  resolutions  of the
Board of Directors  attached thereto,  filed with the Company) of the portion of
the assets or  evidences of  indebtedness  or shares so  distributed  or of such
subscription rights or options applicable to one share of the Common Stock. Such
adjustment shall be made whenever any such distribution is made and shall become
effective retroactively  immediately after the record date for the determination
of stockholders entitled to receive such distribution.

          (d) If the Common Stock  issuable  upon the  conversion  of the Option
shall be changed  into the same or a different  number of shares of any class or
classes  of  stock,  whether  by  capital  reorganization,  reclassification  or
otherwise  (other than a subdivision  or combination of shares or stock dividend
provided for above, or a reorganization, merger, consolidation or sale of assets
provided  for in this  Section 6),  then,  and in each such event,  the Optionee
shall have the right  thereafter to convert such Option into the kind and amount
of shares of Common Stock and other securities and property receivable upon such
reorganization, reclassification or other change by the holders of the number of
shares of Common  Stock into which such  Option  might have been  converted,  as
reasonably   determined   by  the   Committee,   immediately   prior   to   such
reorganization, reclassification or change, all subject to further adjustment as
provided herein.

          (e) If at any  time or from  time to time  there  shall  be a  capital
reorganization  of the Common  Stock  (other  than a  subdivision,  combination,
reclassification or exchange of shares provided for elsewhere in this Section 6)
or a merger or consolidation of the Company with or into another corporation, or
the sale of all or substantially  all of the Company's  properties and assets to
any other person  (except as provided for in Section  6(f)),  then, as a part of
such reorganization,  merger,  consolidation or sale, provision shall be made as
reasonably  determined by the Committee so that the Optionee shall thereafter be
entitled to receive  upon  conversion  of such  Option,  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  or sale,  to which a
holder of Common Stock  deliverable  upon conversion would have been entitled on
such capital reorganization, merger, consolidation or sale.

          (f) The adjustments  provided for in this Section 6 are cumulative and
shall apply to successive  divisions,  subdivisions,  reductions,  combinations,
consolidations,   issue,  distributions  or  other  events  contemplated  herein
resulting in any adjustment under the provisions of this Section; provided that,
notwithstanding  any other  provision  of this  Section,  no  adjustment  of the
Purchase  Price  shall be  required  unless  such  adjustment  would  require an
increase  or  decrease  of at least 1% in the  Purchase  Price  then in  effect;
provided,  however,  that any adjustments which by reason of this subsection (f)
are not  required to be made shall be carried  forward and taken into account in
any subsequent adjustment.


                                      E-105

<PAGE>



          (g)  Notwithstanding  Sections 6(b) and (c) above, no adjustment shall
be made  in the  Purchase  Price  if  provision  is made  for  the  Optionee  to
participate  in such  distribution  as if the Optionee had  converted all of the
principal  balance of the Option  into  shares of Common  Stock at the  Purchase
Price in effect immediately prior to such distribution.

          (h) Upon each adjustment of the Purchase Price, the Company shall give
prompt  written  notice  thereof  addressed  to the  Optionee at the  Optionee's
address as shown on the records of the  Company,  which  notice  shall state the
Purchase Price resulting from such  adjustment and the increase or decrease,  if
any, in the number of shares  issuable upon the  conversion  of such  Optionee's
Option,  setting forth in reasonable  detail the method of  calculation  and the
facts upon which such calculation is bases.

          (i)  In  the  event  of  any  question  arising  with  respect  to the
adjustments  provided  for in Section  6, such  question  shall be  conclusively
determined by an opinion of independent  certified public accountants  appointed
by the Company (who may be the auditors of the  Company) and  acceptable  to the
Optionee.  Such  accountants  shall have access to all necessary  records of the
Company,  and such  determination  shall be  binding  upon the  Company  and the
Optionee.

          (j) The Company may, in its sole discretion and without any obligation
to do so,  reduce  the  Purchase  Price then in effect by giving  fifteen  days'
written  notice to the Optionee.  The Company may limit such reduction as to its
temporal duration or may impose other conditions thereto in its sole discretion.

     7. Acceleration of Right to Exercise Options.  Notwithstanding  anything to
the contrary  contained  herein  regarding the time for exercise of this Option,
the following provisions shall apply:

          (a) Mergers  and  Reorganizations.  If the Company or its  shareholder
enter into an agreement to dispose of all or substantially  all of the assets of
the Company by means of a sale,  merger or other  reorganization of liquidation,
or  otherwise  in a  transaction  in  which  the  Company  is not the  surviving
corporation,  this Option shall become  immediately  exercisable with respect to
the full number of Shares subject to the Option during the period  commencing as
of the date of the  agreement  to  dispose  of all or  substantially  all of the
assets or stock of the  Company  and ending  when the  disposition  of assets or
stock  contemplated  by the agreement is consummated or this Option is otherwise
terminated in  accordance  with its  provisions,  whichever  occurs first.  This
Option shall not become  immediately  exercisable,  however,  if the transaction
contemplated in the agreement is a merger or reorganization in which the Company
will survive.

          (b)  Change  in  Control.  In the  event of a  change  in  control  or
threatened  change  in  control  of  the  Company,   this  Option  shall  become
immediately  exercisable.  The term  "change in  control,"  for purposes of this
Section,  shall  refer to the  acquisition  of 20 per cent or more of the voting
securities  of the Company by any person or by persons  acting as a group within
the  meaning of Section  13(d)(3) of the  Securities  Exchange  Act of 1934,  as
amended;  provided  that no change in  control or  threatened  change in control
shall be deemed to have  occurred if, prior to the  acquisition  of, or offer to


                                      E-106

<PAGE>


acquire,  20 per cent or more of the voting securities of the Company,  the full
Board of  Directors  shall  have  adopted  by not less  than  two-thirds  vote a
resolution  specifically  approving such acquisition or offer. The term "person"
refers,  for  purposes  of this  Section,  to an  individual  or a  corporation,
partnership,   trust,   association,   joint  venture,  pool,  syndicate,   sole
proprietorship,  unincorporated  organization  or any other  form of entity  not
specifically  listed herein.  Whether a change in control is threatened shall be
determined solely by the Committee.

     8. Restrictions on Transfer.

          (a) This  option may not be sold,  assigned,  transferred,  pledged or
otherwise  disposed of or encumbered in any manner  otherwise  than by will, the
laws of descent and distribution,  or pursuant to a qualified domestic relations
order as defined by the Code; provided, however, that the Optionee may assign or
transfer  this Option to members of his  immediate  family or to a trust for the
benefit of such members of his immediate  family and, during the lifetime of the
Optionee,  this Option may be exercised only by the Optionee or assignee, as the
case may be, or his legally  authorized  representative.  The Optionee shall not
have any right to sell,  assign,  transfer,  pledge or  otherwise  dispose of or
encumber this Option, and any attempted transfer,  sale,  assignment,  pledge or
encumbrance shall have no effect on the Company.  The Company may also require a
Optionee to furnish  evidence  satisfactory to the Company,  including a written
and  signed  representation  letter  and  consent  to be bound  by any  transfer
restrictions  imposed by law, legend,  condition or otherwise.  The Shares shall
not be issued with respect to any Option unless the exercise of the Option shall
comply  with the  terms  and  conditions  of the  Consulting  Agreement  and all
relevant  provisions of federal and state law,  including without limitation the
Securities  Act of 1933,  as  amended,  the  rules and  regulations  promulgated
thereunder and the  requirements of any stock exchange upon which the Shares may
then be listed,  and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

          (b)  The  Optionee,  by its  acceptance  hereof,  represents,  opines,
covenants  and agrees that (i) the  Optionee  has  knowledge of the business and
affairs of the Company,  and (ii) this Option is being  acquired for  investment
and not with a view to the  distribution  hereof and that,  absent an  effective
registration statement under the Securities Act of 1933, as amended (the "Act"),
covering  the  disposition  of this  Option,  it will not be sold,  transferred,
assigned,  hypothecated  or otherwise  disposed of without  first  providing the
Company  with an opinion of counsel  (which may be counsel  for the  Company) or
other evidence,  reasonably  acceptable to the Company,  to the effect that such
sale, transfer, assignment,  hypothecation or other disposal will be exempt from
the  registration and prospectus  delivery  requirements of the Act, as amended,
and the  registration  or  qualification  requirements  of any applicable  state
securities  laws.  The  Optionee  consents  to the making of a  notation  in the
Company's  records  or giving to any  transfer  agent of the  Option an order to
implement such restriction on transferability.

          This  Option  shall bear the  following  legend or a legend of similar
import; provided, however, that such legend shall be removed, or not placed upon
the Option if such legend is no longer  necessary to assure  compliance with the
Act:


                                      E-107

<PAGE>



     THIS OPTION HAS NOT BEEN REGISTERED WITH THE UNITED STATES  SECURITIES
     AND EXCHANGE  COMMISSION  OR THE  SECURITIES  COMMISSION  OF ANY STATE
     BECAUSE IT IS BELIEVED TO BE EXEMPT FROM  REGISTRATION  UNDER THE ACT.
     THIS  OPTION IS  "RESTRICTED"  AND MAY NOT BE  RESOLD  OR  TRANSFERRED
     EXCEPT  AS  PERMITTED  UNDER  THE  ACT  PURSUANT  TO  REGISTRATION  OR
     EXEMPTION THEREFROM.

     9.  Information  to Optionee.  The Company  shall furnish to the Optionee a
copy of the annual  report,  proxy  statements and all other reports sent to the
Company's  shareholders.  Upon written request, the Company shall furnish to the
Optionee a copy of its most recent Annual Report on Form 10-K and each quarterly
report to shareholders  issued since the end of the Company's most recent fiscal
year.

     10.  Payment of Taxes.  All Shares  issued upon the exercise of this Option
shall be validly issued,  fully-paid and nonassessable and the Company shall pay
all taxes and other  governmental  charges  (other  than income tax) that may be
imposed in respect of the issue or delivery  thereof.  The Company  shall not be
required, however, to pay any tax or other charge imposed in connection with any
transfer  involved in the issue of any  certificate for Shares in any name other
than that of the Optionee  surrendered  in connection  with the purchase of such
Shares,  and in such case the Company  shall not be required to issue or deliver
any stock  certificate  until  such tax or other  charge has been paid or it has
been  established to the Company's  satisfaction  that no tax or other charge is
due.

     11. Reservation of Common Stock. The Company shall at all times reserve and
keep available out of its authorized but unissued shares of Common Stock, solely
for the purpose of issuance  upon the  exercise of this  Option,  such number of
shares  of Common  Stock as shall be  issuable  upon the  exercise  hereof.  The
Company  covenants and agrees that,  upon exercise of this Option and payment of
the  Purchase  Price  thereof,  all Shares of Common  Stock  issuable  upon such
exercise shall be duly and validly issued, fully-paid and nonassessable.

     12.  Notices  to  Optionee.  Nothing  contained  in this  Option  shall  be
construed as conferring upon the Optionee hereof the right to vote or to consent
or to  receive  notice  as a share-  Optionee  in  respect  of any  meetings  of
share-Optionees  for the  election of directors or any other matter or as having
any rights whatsoever as a share-Optionee of the Company. All notices, requests,
consents  and other  communications  hereunder  shall be in writing and shall be
deemed  to have  been duly made  when  delivered  or  mailed  by  registered  or
certified mail, postage prepaid, return receipt requested:

          (a) If to the  Optionee,  to the address of such  Optionee as shown on
the books of the Company; or

          (b) If to the  Company,  to the  address  set  forth in  Section  1(b)
hereof.


                                      E-108

<PAGE>



     13. Replacement of Option. Upon receipt of evidence reasonably satisfactory
to the  Company  of the  ownership  of  and  the  loss,  theft,  destruction  or
mutilation  of this  Option  and (in case of loss,  theft or  destruction)  upon
delivery of an indemnity  agreement in an amount reasonably  satisfactory to the
Company,  or (in the case of mutilation)  upon surrender and cancellation of the
mutilated Option,  the Company will execute and deliver,  in lieu thereof, a new
Option of like tenor.

     14.  Successors.  All  the  covenants,   agreements,   representations  and
warranties  contained  in this Option  shall bind the  parties  hereto and their
respective  heirs,  executors,  administrators,   distributees,  successors  and
assigns.

     15. Change; Waiver. Neither this Option nor any term hereof may be changed,
waived,  discharged or terminated  verbally but only by an instrument in writing
signed by the party against which enforcement of the change,  waiver,  discharge
or termination is sought.

     16. Headings. The section headings in this Option are inserted for purposes
of convenience only and shall have no substantive effect.

     17. Law  Governing.  This Option shall for all  purposes be  construed  and
enforced in accordance  with, and governed by, the internal laws of the State of
California, without giving effect to principles of conflict of laws.

     IN WITNESS WHEREOF,  the Company has caused this Option to be signed by its
duly  authorized  officer and this Option to be dated as of the date first above
written.

                                OPTION AGREEMENT


     This Option Agreement (the  "Agreement") is made and entered into effective
as of January 27, 1999 by and between  Pollution  Research and Control  Corp., a
California corporation ("PRCC") and Rosemary Althaus ("Optionee").

     WHEREAS, Optionee has been providing valuable services as recognized by the
Company's  Board of  Directors  to PRCC and PRCC is desirous of having  Optionee
continue to provide such services to it; and

     WHEREAS,  PRCC is willing to grant  Optionee an option to purchase up to an
aggregate  of 5,000 shares of the no par value common stock of PRCC (the "Common
Stock") under the terms and conditions set forth below.

     NOW, THEREFORE, the parties agree as follows:

     1. Grant of Option. PRCC hereby grants to Optionee, as a matter of separate
agreement  and not in lieu of other  compensation  for  services,  the right and
option (the  "Option") to purchase on the terms and conditions set forth in this
Agreement  all or any part of up to an aggregate of 5,000 shares of Common Stock
(the "Option Shares"), for continuous, uninterrupted, employment service to PRCC
or by specific acknowledgement of exception by the Company's Board of Directors.

     2.  Option  Price.  At any time  when  shares  of  Common  Stock  are to be
purchased pursuant to the Option, the purchase price for each Option share shall
be $.75  ("Option  Price"),  and for  purposes  of record,  the bid price of the
Company's stock on this date was $1.00.

     3. Option Period. The option period shall commence on January 27, 1999 (the
"Date of Grant") and shall terminate January 27, 2002.

     4.  Exercise of Option.  The Option may be exercised in whole or in part at
any time after the date hereof by delivering to the Chief  Financial  Officer of
PRCC (a) a Notice and Agreement of Exercise of Option, substantially in the form
attached  hereto as Exhibit  "A,"  specifying  the number of Option  Shares with
respect to which the  Option is  exercised,  and (b) full  payment of the Option
Price for such Shares.

     5. Securities Laws Requirements. The Option Shares have not been registered
under the Securities  Act of 1933, as amended (the "Act"),  and no Shares may be


                                      E-114

<PAGE>




sold, offered for sale, transferred, pledged, hypothecated or otherwise disposed
of except in compliance with the Act and any other applicable  federal and state
securities  laws.  Additionally,  the Option and the Option Shares have not been
qualified  under  the  California  Securities  Law  of  1968,  as  amended  (the
"California  Law").  PRCC has no  obligation to register the Option shares under
the Act or  qualify  the  Option  Shares  under  the  California  Law.  Optionee
acknowledges  that  she  is  aware  that  Rule  144  of the  General  Rules  and
Regulations  under  the Act  ("Rule  144")  affords  a  limited  exemption  from
registration for the public resale of registered  securities and under the terms
of Rule 144 as currently in effect,  the Shares received by Optionee may be sold
to the  public  without  registration  only  after a period of two (2) years has
elapsed from the exercise  date of the Option and then only in  compliance  with
all other  requirements of Rule 144 and the Act.  Optionee hereby  acknowledges,
represents, warrants and agrees as follows:

          (a) That the Option and the Option Shares are not registered under the
Act or  qualified  under the  California  Law,  and the Option  Shares shall be,
acquired  solely for the account of Optionee for  investment  purposes  only and
with no view to their resale or other distribution of any kind;

          (b) Neither the Option nor any Option Share shall be sold or otherwise
distributed in violation of the Act, the California Law or any other  applicable
federal or state securities law;

          (c) Her  overall  commitment  to  investments  that  are  not  readily
marketable is not  disproportionate to her net worth, and her investment in PRCC
will not cause such overall commitment to become excessive;

          (d) She has the  financial  ability to bear the  economic  risk of her
investment,  has adequate  means of providing for her current needs and personal
contingencies, and has no need for liquidity in her investment in PRCC;

          (e)  She  either:   (i)  has  a   preexisting   personal  or  business
relationship  with PRCC or its officers,  directors or controlling  persons,  or
(ii) has evaluated the business of PRCC and the high risks of investing in PRCC,
the  competitive  nature of the  business in which PRCC is engaged,  and has the
business or financial experience or has business or  financial  advisors who are

                                      E-115

<PAGE>



unaffiliated  with,  and not  compensated  by, PRCC and protect her interests in
connection with the transaction;

          (f) She has been given the  opportunity  to review all books,  records
and  documents  of PRCC and to ask  questions  and  receive  answers  from  PRCC
concerning PRCC's business, to obtain additional information necessary to verify
the  accuracy  of the  information  she has  desired  in order to  evaluate  her
investment,  and to consult with such attorneys,  accountants and other advisors
as she has desired;

          (g) Her residence  set forth below is her true and correct  residence,
and she has no present  intention of becoming a resident or  domiciliary  of any
other state of jurisdiction;
 
          (h) In making the  decision to accept the Option  and/or  purchase the
Option Shares, she has relied solely upon independent  investigations made by or
on behalf of him;

          (i) No federal or state  agency has made any finding or  determination
as to the fairness of an investment in PRCC; and

          (j) She understands that all the  representations  and warranties made
by him herein,  and all information  furnished by him to PRCC, is true,  correct
and complete in all respects.

     6. Optionee hereby  acknowledges that she understands the meaning and legal
consequences of the  representations,  warranties and covenants contained herein
and that PRCC has relied on the representations  made by Optionee in paragraph 5
hereof in granting  this  Option,  and  Optionee  agrees to  indemnify  and hold
harmless  PRCC and its  officers,  directors,  controlling  persons,  attorneys,
agents and  employees  from and against any and all loss,  damage or  liability,
together   with  all  costs  and  expenses   (including   attorneys'   fees  and
disbursements)  which  any of them may incur by  reason  of any  breach  and any
representation,   warranty,   covenant  or  agreement   contained  herein.   All
representations,  warranties,  covenants and agreements, and the indemnification
contained  herein shall  survive the grant of the Option and the issuance of the
Option Shares by PRCC.

     7.  Legend of  Certificates.  All Option  Shares  issued  pursuant  to this
Agreement  shall  be  subject  to the  provisions  of  this  Agreement  and  the
certificates  representing such Option Shares shall bear the following legend or
language substantially equivalent thereto:

     SO  REGISTERED  OR  QUALIFIED  OR  UNLESS  AN  EXEMPTION  EXISTS,  THE
     AVAILABILITY OF WHICH IS TO BE ESTABLISHED TO THE  SATISFACTION OF THE
     COMPANY."

     8.  Transferability of Option. The Option shall not be transferable  except
by the laws of descent and  distribution and any attempt to do so shall void the
Option.
                
     9.  Adjustment.  The Option Price and the number and kind of Option  Shares
shall be subject to  corresponding  adjustment in the event of any change in the
Common  stock by reason  of any  reclassification,  recapitalization,  split-up,
combination,  exchange of shares, readjustment or stock dividend, in like manner
as if such  Option  Shares  had been  issued  and  outstanding,  fully  paid and
non-assessable at the time of such occurrence.
                 
     10. Privilege of Ownership.  Optionee shall not have any of the rights of a
shareholder  with  respect  to the shares  covered  by the Option  except to the

Pollution Research and Control Corp.
506 Paula Avenue
Glendale, California 91201

Gentlemen:

     In  connection  with the  acquisition  by the  undersigned  of 25,000 units
consisting of 25,000 shares of common stock, no par value per share (the "Common
Stock") and 25,000 common stock purchase  warrants  ("Warrants")  exercisable at
$0.75 per share, at a combined per unit price of $0.75 (75% of the bid price per
share of Common  Stock as of February  25,  1999),  of  Pollution  Research  and
Control Corp. (the  "Company"),  in  consideration  for the sum of $18,750.00 in
cash, the undersigned  wishes to advise you of his  understanding  of, agreement
with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph 4(1) or Paragraph 4(2) of the Act and the Rules and Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

     The shares  represented by this  certificate  have not been registered
     under the  Securities  Act of 1933 (the  "Act"),  and are  "restricted
     securities"  as the term is  defined  in Rule 144 under  the Act.  The
     shares  may not be offered  for sale,  sold or  otherwise  transferred
     except pursuant to an effective  registration statement under the Act,
     or pursuant  to an  exemption  from  registration  under the Act,  the
     availability of which is to be established to the  satisfaction of the
     Company.


                                   E-120

<PAGE>



     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act is  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation  A under the Act and that the  Company  has no  obligation  to do so,
other than via the registration rights referred to in the following  paragraphs.
The undersigned also has been advised and acknowledges that he understands that,
in the event Rule 144 is not  available,  the  circumstances  under which he can
sell the  securities,  absent  registration or compliance with Regulation A, are
extremely limited.

     In the event,  during the period commencing on the date hereof and expiring
three years from the date hereof (February 25, 2002), the Company shall register
any private, primary or secondary offering of any debt or equity security issued
or to be issued by it pursuant to a registration  statement under the Securities
Act of 1933, as amended,  pursuant to which the common stock and the  securities
underlying  the common stock purchase  warrants can be  registered,  the Company
shall in each such event notify the  undersigned in writing not less than thirty
(30) days prior to filing such registration  statement with the Commission,  and
the  undersigned  will  have the  right to  register  all of the  aforementioned
securities  therewith by notifying  the Company in writing  within  fifteen (15)
days  of  receipt  of  the  Company's  notice,  requesting  registration  of the
securities and setting forth the intended method of distribution  and such other
data or information as the Company or its counsel reasonably shall require.  Any
registration  costs shall be borne by the Company,  except for sales commissions
and  related  fees  and/or   transfer  taxes  incurred  if  the  securities  are
subsequently sold.

     Warrants:  The  purchase  rights  evidenced  by the common  stock  purchase
warrants  may be  exercised  in whole or in part at any  time,  and from time to
time,  on or after  the  date  hereof  but  before  February  25,  2002,  by the
undersigned through the presentation and surrender of the warrant to the Company
at its principal  office or at the office of the Company's stock transfer agent,
if any, accompanied by a duly executed Notice of Exercise,  in the form attached
hereto as Exhibit A.

     Adjustments: Stock Dividends,  Reclassifications,  Merger and Anti-Dilution
Provisions.

     (a)  If the Company  increases  or  decreases  the number of its issued and
          outstanding  shares of Common Stock,  or changes in any way the rights
          and privileges of such shares,  by means of (i) the Common Stock, (ii)
          

                                      E-121

          a forward or reverse stock split or other subdivision of shares, (iii)
          a consolidation  or combination  involving its Common Stock, or (iv) a
          reclassification or recapitalization  involving its Common Stock, then
          the  Warrant  Exercise  Price in effect at the time of such action and
          the number os Shares  shall be  proportionately  adjusted  so that the

Pollution Research and Control Corp.

Glendale, California 91201

Gentlemen:

     In connection  with the  acquisition  by the  undersigned  of 133,333 units
consisting  of  133,333  shares of  common  stock,  no par value per share  (the
"Common  Stock")  and  133,333  common  stock  purchase  warrants   ("Warrants")
exercisable  at $0.75 per share,  at a combined  per unit price of $0.75 (75% of
the bid price per share of Common Stock as of February 25,  1999),  of Pollution
Research and Control Corp.  (the  "Company"),  in  consideration  for the sum of
$99,999.75 in cash, the  undersigned  wishes to advise you of his  understanding
of, agreement with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph 4(1) or Paragraph 4(2) of the Act and the Rules and Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

     The shares  represented by this  certificate  have not been registered
     under the  Securities  Act of 1933 (the  "Act"),  and are  "restricted
     securities"  as the term is  defined  in Rule 144 under  the Act.  The
     shares  may not be offered  for sale,  sold or  otherwise  transferred
     except pursuant to an effective  registration statement under the Act,
     or pursuant  to an  exemption  from  registration  under the Act,  the
     availability of which is to be established to the  satisfaction of the
     Company.

                                   E-127

<PAGE>



     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act is  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation  A under the Act and that the  Company  has no  obligation  to do so,
other than via the registration rights referred to in the following  paragraphs.
The undersigned also has been advised and acknowledges that he understands that,
in the event Rule 144 is not  available,  the  circumstances  under which he can
sell the  securities,  absent  registration or compliance with Regulation A, are
extremely limited.

     In the event,  during the period commencing on the date hereof and expiring
three years from the date hereof (February 25, 2002), the Company shall register
any private, primary or secondary offering of any debt or equity security issued
or to be issued by it pursuant to a registration  statement under the Securities
Act of 1933, as amended,  pursuant to which the common stock and the  securities
underlying  the common stock purchase  warrants can be  registered,  the Company
shall in each such event notify the  undersigned in writing not less than thirty
(30) days prior to filing such registration  statement with the Commission,  and
the  undersigned  will  have the  right to  register  all of the  aforementioned
securities  therewith by notifying  the Company in writing  within  fifteen (15)
days  of  receipt  of  the  Company's  notice,  requesting  registration  of the
securities and setting forth the intended method of distribution  and such other
data or information as the Company or its counsel reasonably shall require.  Any
registration  costs shall be borne by the Company,  except for sales commissions
and  related  fees  and/or   transfer  taxes  incurred  if  the  securities  are
subsequently sold.

     Warrants:  The  purchase  rights  evidenced  by the common  stock  purchase
warrants  may be  exercised  in whole or in part at any  time,  and from time to
time,  on or after  the  date  hereof  but  before  February  25,  2002,  by the
undersigned through the presentation and surrender of the warrant to the Company
at its principal  office or at the office of the Company's stock transfer agent,
if any, accompanied by a duly executed Notice of Exercise,  in the form attached
hereto as Exhibit A.

     Adjustments: Stock Dividends,  Reclassifications,  Merger and Anti-Dilution
Provisions.

     (a)  If the Company  increases  or  decreases  the number of its issued and
          outstanding  shares of Common Stock,  or changes in any way the rights
          and privileges of  such shares, by means of (i) the Common Stock, (ii)

          a consolidation  or combination  involving its Common Stock, or (iv) a

          the  Warrant  Exercise  Price in effect at the time of such action and
          the number os Shares  shall be  proportionately  adjusted  so that the
          numbers,  rights,  and privileges  relating to the Securities shall be
          increased, decreased or changed in like manner.

     (b)  If at any time or from time to time the Company  should  issue or sell
          any shares of Common  Stock,  including  shares held in the  Company's
          Treasury,  without consideration or for a per share consideration less
          that the Warrant  Exercise price of $0.75 per share,  then the Warrant
          Exercise  price of $0.75 shall be  adjusted  downward  accordingly  to
          equal the per share  consideration  received by the  Company  upon the
          issuance or sale of its Common Stock.

     The undersigned further  acknowledges and represents to the Company that he
is purchasing the securities for his own account and not as a trustee or nominee
for any other person or persons,  and that the funds or  consideration  invested
are his own. The undersigned further  acknowledges and represents that there are

Pollution Research and Control Corp.
506 Paula Avenue
Glendale, California 91201

Gentlemen:

     In  connection  with the  acquisition  by the  undersigned  of 66,666 units
consisting of 66,666 shares of common stock, no par value per share (the "Common
Stock") and 66,666 common stock purchase  warrants  ("Warrants")  exercisable at
$0.75 per share, at a combined per unit price of $0.75 (75% of the bid price per
share of Common  Stock as of February  25,  1999),  of  Pollution  Research  and
Control Corp. (the  "Company"),  in  consideration  for the sum of $49,999.50 in
cash, the undersigned  wishes to advise you of his  understanding  of, agreement
with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph 4(1) or Paragraph 4(2) of the Act and the Rules and Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

     The shares  represented by this  certificate  have not been registered
     under the  Securities  Act of 1933 (the  "Act"),  and are  "restricted
     securities"  as the term is  defined  in Rule 144 under  the Act.  The
     shares  may not be offered  for sale,  sold or  otherwise  transferred
     except pursuant to an effective  registration statement under the Act,
     or pursuant  to an  exemption  from  registration  under the Act,  the
     availability of which is to be established to the  satisfaction of the
     Company.


                                   E-134

<PAGE>



     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act is  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation  A under the Act and that the  Company  has no  obligation  to do so,
other than via the registration rights referred to in the following  paragraphs.
The undersigned also has been advised and acknowledges that he understands that,
in the event Rule 144 is not  available,  the  circumstances  under which he can
sell the  securities,  absent  registration or compliance with Regulation A, are
extremely limited.

     In the event,  during the period commencing on the date hereof and expiring
three years from the date hereof (February 25, 2002), the Company shall register
any private, primary or secondary offering of any debt or equity security issued
or to be issued by it pursuant to a registration  statement under the Securities
Act of 1933, as amended,  pursuant to which the common stock and the  securities
underlying  the common stock purchase  warrants can be  registered,  the Company
shall in each such event notify the  undersigned in writing not less than thirty
(30) days prior to filing such registration  statement with the Commission,  and
the  undersigned  will  have the  right to  register  all of the  aforementioned
securities  therewith by notifying  the Company in writing  within  fifteen (15)
days  of  receipt  of  the  Company's  notice,  requesting  registration  of the
securities and setting forth the intended method of distribution  and such other
data or information as the Company or its counsel reasonably shall require.  Any
registration  costs shall be borne by the Company,  except for sales commissions
and  related  fees  and/or   transfer  taxes  incurred  if  the  securities  are
subsequently sold.

     Warrants:  The  purchase  rights  evidenced  by the common  stock  purchase
warrants  may be  exercised  in whole or in part at any  time,  and from time to
time,  on or after  the  date  hereof  but  before  February  25,  2002,  by the
undersigned through the presentation and surrender of the warrant to the Company
at its principal  office or at the office of the Company's stock transfer agent,
if any, accompanied by a duly executed Notice of Exercise,  in the form attached
hereto as Exhibit A.

     Adjustments: Stock Dividends,  Reclassifications,  Merger and Anti-Dilution
Provisions.

     (a)  If the Company  increases  or  decreases  the number of its issued and
          outstanding  shares of Common Stock,  or changes in any way the rights
          and  privileges of such shares, by means of (i) the Common Stock, (ii)

                                      E-135

<PAGE>



          a forward or reverse stock split or other subdivision of shares, (iii)
          a consolidation  or combination  involving its Common Stock, or (iv) a
          reclassification or recapitalization  involving its Common Stock, then
          the  Warrant  Exercise  Price in effect at the time of such action and
          the number os Shares  shall be  proportionately  adjusted  so that the
          numbers,  rights,  and privileges  relating to the Securities shall be
          increased, decreased or changed in like manner.

     (b)  If at any time or from time to time the Company  should  issue or sell
          any shares of Common  Stock,  including  shares held in the  Company's
          Treasury,  without consideration or for a per share consideration less
          that the Warrant  Exercise price of $0.75 per share,  then the Warrant
          Exercise  price of $0.75 shall be  adjusted  downward  accordingly  to
          equal the per share  consideration  received by the  Company  upon the
          issuance or sale of its Common Stock.

     The undersigned further  acknowledges and represents to the Company that he
is purchasing the securities for his own account and not as a trustee or nominee
for any other person or persons,  and that the funds or  consideration  invested
are his own. The undersigned further  acknowledges and represents that there are
no  existing  legal  restrictions  applicable  to him which would  preclude  his
acquisition of the securities for investment purposes, as described hereinabove.
The  undersigned  further  represents that he has no present plans to enter into
any contract,  undertaking,  agreement or arrangement for resale,  distribution,
subdivision or fractionalization of the securities purchased hereby.

     The undersigned further acknowledges that he understands that an investment
in the Company is extremely speculative and subject to a high degree of risk. In
this  connection,  the  undersigned  understands  that he may  lose  his  entire
investment in the Company.

     The undersigned further  acknowledges and represents to the Company that he
is able  to  bear  the  economic  risk of  losing  his  entire  investment.  The
undersigned  further  acknowledges  and warrants that his overall  commitment to
investments which are not readily marketable is not  disproportionate to his net
worth  and  his  investment  in the  securities  will  not  cause  such  overall
commitment to become excessive.  The undersigned  further represents that he has
adequate means of providing for his current needs and personal contingencies and
that he has no need for  liquidity  in  connection  with his  investment  in the
securities.  The undersigned further  acknowledges that he fully understands and
agrees  that  the  price  of  the  Company's  securities  acquired  by  him  was
arbitrarily  determined  without  regard  to any  value of the  securities.  The
undersigned understands, additionally, that the price of the securities bears no
relation  to the value of the  assets or net worth of the  Company  or any other
criteria of value.  The undersigned is aware that no independent  evaluation has
been made with respect to the value of the securities.  The undersigned  further
understands  and agrees that shares of the common stock of the Company have been
or may in the  future be issued to certain  other  persons  for a  consideration
which may be less than the price paid by him for the securities.

     The undersigned further  acknowledges and represents to the Company that he
is knowledgeable and experienced in venture capital  investments in general and,
in  particular, with respect to  investments  similar in nature to an investment

                                OPTION AGREEMENT


     This Option Agreement (the  "Agreement") is made and entered into effective
as of February 26, 1999 by and between  Pollution  Research and Control Corp., a
California corporation ("PRCC") and Anthony Reneau ("Optionee").

     WHEREAS, Optionee has been providing valuable services as
recognized by the  Company's  Board of Directors to PRCC and PRCC is desirous of
having Optionee continue to provide such services to it; and

     WHEREAS,  PRCC is willing to grant  Optionee an option to purchase up to an
aggregate of 25,000 shares of the no par value common stock of PRCC (the "Common
Stock") under the terms and conditions set forth below.

     NOW, THEREFORE, the parties agree as follows:

     1. Grant of Option. PRCC hereby grants to Optionee, as a matter of separate
agreement  and not in lieu of other  compensation  for  services,  the right and
option (the  "Option") to purchase on the terms and conditions set forth in this
Agreement all or any part of up to an aggregate of 25,000 shares of Common Stock
(the "Option Shares"), for continuous, uninterrupted, employment service to PRCC
or by specific acknowledgement of exception by the Company's Board of Directors.

     2.  Option  Price.  At any time  when  shares  of  Common  Stock  are to be
purchased pursuant to the Option, the purchase price for each Option share shall
be $1.00  ("Option  Price"),  and for  purposes of record,  the bid price of the
Company's stock on this date was $1.38.

"Date of Grant") and shall terminate February 25, 2002.

any time after the date hereof by delivering to the Chief  Financial  Officer of
PRCC (a) a Notice and Agreement of Exercise of Option, substantially in the form
attached  hereto as Exhibit  "A,"  specifying  the number of Option  Shares with
respect to which the  Option is  exercised,  and (b) full  payment of the Option
Price for such Shares.

     5. Securities Laws Requirements. The Option Shares have not been registered
under the Securities  Act of 1933, as amended (the "Act"),  and no Shares may be
sold, offered for sale, transferred, pledged, hypothecated or otherwise disposed
of except in compliance with the Act and any other applicable  federal and state
securities  laws.  Additionally,  the Option and the Option Shares have not been
qualified  under  the  California  Securities  Law  of  1968,  as  amended  (the
"California  Law").  PRCC has no  obligation to register the Option shares under
the Act or  qualify  the  Option  Shares  under  the  California  Law.  Optionee
acknowledges that he is aware that Rule 144 of the General Rules and Regulations
under the Act ("Rule 144") affords a limited exemption from registration for the
public  resale  of  registered  securities  and  under  the terms of Rule 144 as
currently in effect,  the Shares  received by Optionee may be sold to the public
without  registration  only after a period of two (2) years has elapsed from the
exercise  date  of the  Option  and  then  only in  compliance  with  all  other
requirements of Rule 144 and the Act. Optionee hereby acknowledges,  represents,
warrants and agrees as follows:

          (a) That the Option and the Option Shares are not registered under the
Act or  qualified  under the  California  Law,  and the Option  Shares shall be,
acquired  solely for the account of Optionee for  investment  purposes  only and
with no view to their resale or other distribution of any kind;

          (b) Neither the Option nor any Option Share shall be sold or otherwise
distributed in violation of the Act, the California Law or any other  applicable
federal or state securities law;

          (c) His  overall  commitment  to  investments  that  are  not  readily
marketable is not  disproportionate to his net worth, and his investment in PRCC
will not cause such overall commitment to become excessive;
                         
          (d) He has the  financial  ability  to bear the  economic  risk of his
investment,  has adequate  means of providing for his current needs and personal
contingencies, and has no need for liquidity in his investment in PRCC;

          (e) He either: (i) has a preexisting personal or business relationship
with  PRCC or its  officers,  directors  or  controlling  persons,  or (ii)  has
evaluated  the  business of PRCC and the high risks of  investing  in PRCC,  the
competitive  nature  of the  business  in  which  PRCC is  engaged,  and has the
business or financial  experience or has business or financial  advisors who are
unaffiliated  with,  and not  compensated  by, PRCC and protect his interests in
connection with the transaction;


                                      E-143

<PAGE>




          (f) He has been given the opportunity to review all books, records and
documents of PRCC and to ask questions and receive  answers from PRCC concerning
PRCC's  business,  to obtain  additional  information  necessary  to verify  the
accuracy of the  information he has desired in order to evaluate his investment,
and to consult with such  attorneys,  accountants  and other  advisors as he has
desired;
                          
          (g) His residence  set forth below is his true and correct  residence,
and he has no present  intention  of becoming a resident or  domiciliary  of any
other state of jurisdiction;
                           
          (h) In making the  decision to accept the Option  and/or  purchase the
Option Shares, he has relied solely upon independent  investigations  made by or
on behalf of him;
                           
          (i) No federal or state  agency has made any finding or  determination
as to the fairness of
an investment in PRCC; and
                           
          (j) He understands that all the representations and warranties made by
him herein,  and all information  furnished by him to PRCC, is true, correct and
complete in all respects.
             
     6. Optionee hereby acknowledges that he understands the
meaning and legal consequences of the representations,  warranties and covenants
contained  herein  and  that  PRCC has  relied  on the  representations  made by
Optionee in paragraph 5 hereof in granting this Option,  and Optionee  agrees to
indemnify  and hold  harmless  PRCC  and its  officers,  directors,  controlling
persons,  attorneys,  agents and  employees  from and  against any and all loss,
damage or liability,  together with all costs and expenses (including attorneys'
fees and disbursements)  which any of them may incur by reason of any breach and
any  representation,  warranty,  covenant or  agreement  contained  herein.  All
representations,  warranties,  covenants and agreements, and the indemnification
contained  herein shall  survive the grant of the Option and the issuance of the
Option Shares by PRCC.

     7.  Legend of  Certificates.  All Option  Shares  issued  pursuant  to this
Agreement  shall  be  subject  to the  provisions  of  this  Agreement  and  the
certificates  representing such Option Shares shall bear the following legend or
language substantially equivalent thereto:


                                      E-144

     SO  REGISTERED  OR  QUALIFIED  OR  UNLESS  AN  EXEMPTION  EXISTS,  THE
     AVAILABILITY OF WHICH IS TO BE ESTABLISHED TO THE  SATISFACTION OF THE
     COMPANY."

     8.  Transferability of Option. The Option shall not be transferable  except
by the laws of descent and  distribution and any attempt to do so shall void the
Option.
               
     9.  Adjustment.  The Option Price and the number and kind of Option  Shares
shall be subject to  corresponding  adjustment in the event of any change in the
Common  stock by reason  of any  reclassification,  recapitalization,  split-up,
combination,  exchange of shares, readjustment or stock dividend, in like manner
as if such  Option  Shares  had been  issued  and  outstanding,  fully  paid and
non-assessable at the time of such occurrence.

Pollution Research and Control Corp.
506 Paula Avenue
Glendale, California 91201

Gentlemen:

     In  connection  with the  acquisition  by the  undersigned  of 14,000 units
consisting of 14,000 shares of common stock, no par value per share (the "Common
Stock") and 14,000 common stock purchase  warrants  ("Warrants")  exercisable at
$0.75 per share, at a combined per unit price of $0.75 (75% of the bid price per
share of Common  Stock as of February  25,  1999),  of  Pollution  Research  and
Control Corp. (the  "Company"),  in  consideration  for the sum of $10,500.00 in
cash, the undersigned  wishes to advise you of his  understanding  of, agreement
with and/or representation of, the following:

     These securities are not being registered under the Securities Act of 1933,
as amended (the "Act"), on the ground that this sale is exempt from registration
under  Paragraph 4(1) or Paragraph 4(2) of the Act and the Rules and Regulations
promulgated  thereunder  as not  involving  any public  offering.  The Company's
reliance on such  exemption is predicated in part on the  representation  of the
undersigned  that he is acquiring  such  securities  for  investment for his own
account,  with no present intention of dividing his participation with others or
reselling  or  otherwise  distributing  the  same.  These  securities  which the
undersigned is acquiring are "restricted  securities" as that term is defined in
Rule 144 of the General  Rules and  Regulations  under the Act. The  undersigned
acknowledges  that  he  understands  that  the  securities  covered  hereby  are
unregistered  and  must be  held  indefinitely,  unless  they  are  subsequently
registered under the Act or an exemption from such registration is available.

     The undersigned  agrees that any and all certificates,  which may be issued
representing the securities acquired hereunder,  shall contain substantially the
following legend, which the undersigned has read and understands:

     The shares  represented by this  certificate  have not been registered
     under the  Securities  Act of 1933 (the  "Act"),  and are  "restricted
     securities"  as the term is  defined  in Rule 144 under  the Act.  The
     shares  may not be offered  for sale,  sold or  otherwise  transferred
     except pursuant to an effective  registration statement under the Act,
     or pursuant  to an  exemption  from  registration  under the Act,  the
     availability of which is to be established to the  satisfaction of the
     Company.


                                      E-148

<PAGE>



     The undersigned understands that the above legend on the certificates would
limit their value, including their value as collateral.

     The  undersigned  further  acknowledges  that he  understands  that, if the
securities  have  been  held for a period  of at least  one year and if Rule 144
adopted  under  the Act is  applicable  (there  being no  representation  by the
Company that this Rule will be applicable),  then he may make only routine sales
of the securities in limited  amounts in a specified  manner in accordance  with
the terms and conditions of the Rule. The undersigned further  acknowledges that
he  understands  that, if Rule 144 is  applicable  (no assurance of which can be
made),  he may sell the  securities  without  quantity  limitation  in sales not
involving a market maker or through  brokerage  transactions only if he has held
the securities for at least two years. In case the Rule is not  applicable,  any
sales  made by the  undersigned  may be made only  pursuant  to other  available
exemption  from  registration  under  the  Act,  or  an  effective  registration
statement.

     The undersigned further acknowledges that he is aware that only the Company
can  file  a  registration  statement  or  an  offering  statement  pursuant  to
Regulation  A under the Act and that the  Company  has no  obligation  to do so,
other than via the registration rights referred to in the following  paragraphs.
The undersigned also has been advised and acknowledges that he understands that,
in the event Rule 144 is not  available,  the  circumstances  under which he can
sell the  securities,  absent  registration or compliance with Regulation A, are
extremely limited.

     In the event,  during the period commencing on the date hereof and expiring
three years from the date hereof (February 25, 2002), the Company shall register
any private, primary or secondary offering of any debt or equity security issued
or to be issued by it pursuant to a registration  statement under the Securities
Act of 1933, as amended,  pursuant to which the common stock and the  securities
underlying  the common stock purchase  warrants can be  registered,  the Company
shall in each such event notify the  undersigned in writing not less than thirty
(30) days prior to filing such registration  statement with the Commission,  and
the  undersigned  will  have the  right to  register  all of the  aforementioned
securities  therewith by notifying  the Company in writing  within  fifteen (15)
days  of  receipt  of  the  Company's  notice,  requesting  registration  of the
securities and setting forth the intended method of distribution  and such other
data or information as the Company or its counsel reasonably shall require.  Any
registration  costs shall be borne by the Company,  except for sales commissions
and  related  fees  and/or   transfer  taxes  incurred  if  the  securities  are
subsequently sold.

     Warrants:  The  purchase  rights  evidenced  by the common  stock  purchase
warrants  may be  exercised  in whole or in part at any  time,  and from time to
time,  on or after  the  date  hereof  but  before  February  25,  2002,  by the
undersigned through the presentation and surrender of the warrant to the Company
at its principal  office or at the office of the Company's stock transfer agent,
if any, accompanied by a duly executed Notice of Exercise,  in the form attached
hereto as Exhibit A.

     Adjustments: Stock Dividends,  Reclassifications,  Merger and Anti-Dilution
Provisions.

     (a)  If the Company  increases  or  decreases  the number of its issued and
          outstanding  shares of Common Stock,  or changes in any way the rights
          and privileges of such shares, by means of  (i) the Common Stock, (ii)

                                      E-149

<PAGE>



          a forward or reverse stock split or other subdivision of shares, (iii)
          a consolidation  or combination  involving its Common Stock, or (iv) a
          reclassification or recapitalization  involving its Common Stock, then
          the  Warrant  Exercise  Price in effect at the time of such action and
          the number os Shares  shall be  proportionately  adjusted  so that the
          numbers,  rights,  and privileges  relating to the Securities shall be
          increased, decreased or changed in like manner.

     (b)  If at any time or from time to time the Company  should  issue or sell
          any shares of Common  Stock,  including  shares held in the  Company's
          Treasury,  without consideration or for a per share consideration less
          that the Warrant  Exercise price of $0.75 per share,  then the Warrant
          Exercise  price of $0.75 shall be  adjusted  downward  accordingly  to
          equal the per share  consideration  received by the  Company  upon the
          issuance or sale of its Common Stock.

     The undersigned further  acknowledges and represents to the Company that he
is purchasing the securities for his own account and not as a trustee or nominee
for any other person or persons,  and that the funds or  consideration  invested
are his own. The undersigned further  acknowledges and represents that there are
no  existing  legal  restrictions  applicable  to him which would  preclude  his
acquisition of the securities for investment purposes, as described hereinabove.
The  undersigned  further  represents that he has no present plans to enter into
any contract,  undertaking,  agreement or arrangement for resale,  distribution,
subdivision or fractionalization of the securities purchased hereby.

     The undersigned further acknowledges that he understands that an investment
in the Company is extremely speculative and subject to a high degree of risk. In
this  connection,  the  undersigned  understands  that he may  lose  his  entire
investment in the Company.

     The undersigned further  acknowledges and represents to the Company that he
is able  to  bear  the  economic  risk of  losing  his  entire  investment.  The
undersigned  further  acknowledges  and warrants that his overall  commitment to
investments which are not readily marketable is not  disproportionate to his net
worth  and  his  investment  in the  securities  will  not  cause  such  overall
commitment to become excessive.  The undersigned  further represents that he has
adequate means of providing for his current needs and personal contingencies and
that he has no need for  liquidity  in  connection  with his  investment  in the
securities.  The undersigned further  acknowledges that he fully understands and
agrees  that  the  price  of  the  Company's  securities  acquired  by  him  was
arbitrarily  determined  without  regard  to any  value of the  securities.  The
