                                   THE COMPANY

         The Company  develops,  manufactures and markets two principal lines of
products:  (i) consumer and  industrial  products  incorporating  the  Company's
proprietary chemical technology,  Eliminate(R), which clean and control scaling,
corrosion and biological  growth on surfaces and containers which are exposed to
water,  and (ii)  biorational  agricultural  products  which  are  comprised  of
components  existing in nature  rather  than  components  that are  artificially
synthesized or man-made.  Until recently, the Company concentrated on developing
its  Eliminate-  based  products  and its water system  treatment  technologies,
obtaining  patents  and  acquiring  CCT  Corporation  ("CCT")  and its  consumer
products division.  The Company currently is focusing on marketing its consumer,
industrial and agricultural products.

                                                       3

         The  Company's  Eliminate  technology  was  developed to respond to the
disadvantages  of  current  methods  of  treating  water  systems.  Many  of the
chemicals  used in treating  water systems are corrosive and can cause  scaling,
and it is often  difficult to achieve and maintain  the correct  combination  of
chemicals. Moreover, to the extent that chemicals used in treating water systems
are toxic, corrosive or non-biodegradable, they are considered to be pollutants,
subjecting  the water systems to expensive  clean-up and  regulatory  compliance
costs.  Many water  systems also require  expensive  monitoring.  The  Company's
Eliminate-based products, when added to water, dissolve and prevent scaling from
the deposit of  water-borne  minerals and corrosion  caused by oxidation,  while
suppressing the environment  that supports  components of scale and corrosion in
solution. Even in its concentrated form, the Eliminate technology is non-fuming,
non-abrasive and non-flammable.  Many of the Company's  Eliminate-based products
are also biodegradable.  The Eliminate-based  products for the industrial market
include Well Klean II(R) and Pipe  Klean(R)  (which  remove  encrustations  from
water pumping and distribution systems), Chlor*Rid(R) (which aids in the removal
of chlorides,  sulfates and other soluble salts from surfaces  prior to coating)
and  Compounds  400,  360, 260, 200, COC 10-30M and Slug (which are designed for
use with the  Eliminate  technology  for  treatment  of cooling  and other water
treatment  systems).  These  products  (other  than  Chlor*Rid  which is sold by
Chlor*Rid International, Inc., an unaffiliated distributor) are sold directly by
the Company.  The Company's  consumer products include Eliminate Shower, Tub and
Tile Cleaner,  Clean  Sweep(R) (a swimming pool  cleaner),  Eliminate  Evaporate
Cooler  Cleaner and  Treatment  (used to clean and maintain  evaporative  cooler
systems) and Eliminate  Toilet Bowl Cleaner and are sold to the consumer  market
by H.E.R.C.  Consumer Products Incorporated  ("HCP"), an Arizona corporation,  a
wholly-owned subsidiary of the Company.

         Through  CCT, the  Company's  wholly-owned  subsidiary  acquired in May
1995, the Company develops, manufactures and markets biorational pest management
and plant growth products for the agricultural and  horticultural  markets.  The
Company believes that, in addition to expanding the Company's  product offerings
through  the  addition  of CCT's  product  lines,  CCT's  established  marketing
organization  will  facilitate the Company's  sales of its existing water system
treatment products, although there can be no assurance of this.

         The Company was incorporated  under the laws of the State of Arizona in
December 1986 and was  reincorporated in the State of Delaware in February 1994.
The Company acquired all of the outstanding  capital stock of CCT on May 1, 1995
in a merger by which CCT became a  wholly-owned  subsidiary of the Company.  CCT
was  incorporated  under  the laws of the  State of  Arizona  in May  1981.  The
Company's  executive offices and manufacturing  facility for its Eliminate-based
products  are located in  Phoenix,  Arizona  and its  telephone  number is (602)
492-0336.  CCT's office is located in  Carlsbad,  California  and its  telephone

         Private Offering. On December 17, 1996, the Company completed a private
equity offering ("Private  Placement") to accredited investors of 170,000 shares
of Class A Preferred Stock  ("Preferred  Stock") pursuant to an Agency Agreement
("Agency Agreement") with Perrin,  Holden & Davenport Capital Corp.  ("Placement
Agent" or "PHD") which acted as the  exclusive  placement  agent for the Private
Placement.  The  Company  received  aggregate  proceeds of  $1,700,000  from the
Private Placement.

   
         The Preferred Stock has a stated value of $10.00 per share. The holders
of the Preferred Stock are entitled to received  dividends at the rate of 10% of
the stated value  ($1.00 per share) per annum from the date of issuance  through
the  conversion  date  ("Conversion  Date"),  payable solely in shares of Common
Stock of the Company.  The holders of Preferred  Stock shall have the right,  at
such holder's option, at any time or from time to time, to convert each share of
Preferred  Stock and the accrued  amount of  dividends  thereon into a number of
shares of Common Stock ("Conversion  Shares")  determined by dividing the stated
value of the Preferred Stock being converted, plus the accrued dividends thereon
through the  Conversion  Date, by the greater of (i) 75% of the average  closing
bid price of the Common  Stock for the five  consecutive  trading  dates  ending
immediately  prior to the date  notice  of  conversion  is given to the  Company
("Fair Market  Value"),  or (ii) $.10.  The Preferred  Stock will  automatically
convert at the above rate on December 17, 1999. Generally, the closing bid price
will be as reported by The Nasdaq Stock  Market,  Inc.,  which is the  principal
market for the Company's Common Stock. The Company will not issue any fractional
shares of Common Stock pursuant to any conversion,  but instead will round up or
down to the  nearest  whole  number  of shares  issuable  upon  conversion.  The
Preferred Stock does not carry
    

                                                       4

any redemption or voting rights.  In the event of a liquidation,  dissolution or
winding up of the Company,  the holders of the Preferred Stock will  participate
with the  holders  of the  Common  Stock as if the  Preferred  Stock  was  fully
converted immediately prior to the event.

   
         For purposes of this Prospectus and the Registration Statement of which
this  Prospectus is a part,  the number of  Conversion  Shares to be received by
Selling  Stockholders upon conversion of the Preferred Stock has been calculated
assuming a conversion rate of $1.3593 and assuming that the maximum three annual
dividend has been paid on the Preferred Stock.

         Registration Rights of Preferred Stock and PHD Warrant. Under the terms
of the Agency Agreement and the subscription agreement with each investor in the
Private Placement,  the Company has agreed to register the re- offer and re-sale
of the Conversion Shares by the Selling  Stockholders by filing the registration
statement of which this Prospectus is a part  ("Registration  Statement")  under
the  Securities  Act with  the  Commission  and the  securities  laws of  states
reasonably  selected by PHD.  The Company has agreed to use its best  efforts to
have the Registration  Statement declared effective by February 14, 1997 and has
undertaken to have it declared  effective by April 15, 1997. If the registration
statement is not declared  effective by April 15, 1997, the  conversion  rate of
the  Preferred  Stock  will be reduced to 72.5% of the Fair  Market  Value.  The
Company will bear all the expenses and pay all the fees  incurred in  connection
with the  preparation,  filing and modification or amendment of the Registration
Statement.
    

         Agency Agreement.  The Company paid the Placement Agent a commission of
$170,000  (10% of the offering  price of the Preferred  Stock).  The Company has
issued to the  Placement  Agent and its  designees  a  five-year  warrant  ("PHD
Warrant") to purchase 85,000 Shares ("PHD Warrant  Shares").  The PHD Warrant is
exercisable  at any time in  whole  or in part  between  December  10,  1996 and
December 10, 2001, at a price per Share of $3.00.  All of the PHD Warrant Shares
are being included in the Registration Statement.

         In connection with the Private Placement,  GKN Securities Corp. ("GKN")
waived its right of first refusal with respect to acting as the placement  agent
for the Private Placement.


                                  RISK FACTORS

         The  Shares  being  offered  hereby are  speculative  and should not be
purchased by anyone who cannot afford a loss of their entire investment.  Before
making an investment in the Company,  prospective  investors should give careful
consideration  to the  following  risk  factors  inherent in and  affecting  the
business of the Company and this offering.

         History of  Losses;  Accumulated  Deficit;  Future  Operating  Results.
During the last several years,  the Company has  concentrated  on developing its
various  technologies,  obtaining  patents and acquiring the business of CCT and
its consumer products  division.  The Company has had substantial losses in each
of the last  three  fiscal  years and  expects  to have  losses  in the  future.
Currently, the Company has an accumulated deficit.  Inasmuch as the Company will
continue to have a high level of operating  expense,  the  Company's  ability to
achieve   future   profitability   will   depend  upon  its  ability  to  attain
corresponding  increases  in revenues.  Given the  Company's  limited  financial
resources,  high level of expenses and the competitive environments in which the
Company  operates,  there can be no  assurance  that the Company will be able to
generate  sufficient  revenues to fund its current  operations.  There can be no
assurance that the Company will be able to generate  sufficient revenues to fund
its current or future operations or that the Company's future operations will be
profitable.

         Significant Capital Requirements;  Need for Additional  Financing.  The
Company's  capital  requirements  have been and will continue to be significant.
The  Company  is not  currently  generating  sufficient  cash  flow to fund  its
operations,  and  there can be no  assurance  that the  Company  will be able to
generate  cash  flows  in the  future  which  will be  sufficient  to  fund  its
operations.  Assuming no change in the level of the business of the Company,  it
is anticipated  that the proceeds from the Private  Placement will be sufficient
to meet its anticipated working capital requirements for approximately 12 months
thereafter.  If additional  financing is needed, the Company will be required to
borrow, sell additional securities or seek other new sources of financing or may
be required to curtail

                                                       5

<PAGE>



or reduce its activities.  The Company has no current  arrangements with respect
to  additional  financing.  There  can  be no  assurance  that  any  sources  of
additional financing will be available to the Company on acceptable terms, or at
all. To the extent that any future financing  involves the sale of the Company's
equity  securities,  the interest of the  Company's  then-stockholders  could be
substantially diluted.

         Dependence on Significant  Customers.  During the Company's most recent
fiscal year, United Agriculture Products, a wholly-owned  subsidiary of ConAgra,
accounted for approximately 15% of the Company's revenues. The Company,  through
CCT, has had a  relationship  with this  customer  since 1981,  formalized  in a
written agreement which is renewable on a yearly basis. During 1996, Home Depot,
Inc. accounted for approximately 30% of the Company revenues.  While the Company
considers its commercial relationship with each of these customers to be good, a
loss of one or both or a significant  decrease in purchases by one or both could
have a material adverse effect on the Company's operations.

         Competition;  Technological and Product  Obsolescence.  The markets for
the  Company's  products  are highly  competitive.  The  Company  competes  with
numerous,   well  established  chemical,   agricultural  and  consumer  products
companies,  all of which possess  substantially  greater experience,  financial,
marketing,  personnel,  and other  resources and have also  established  greater
recognition  for their brand names than the Company.  The Company  believes that
these  competitors  have  the  resources  to  develop  and have  developed,  are
developing,  or may  develop  and  market  products  directly  competitive  with
products  incorporating  the Company's  technology.  Current  competitors or new
market entrants could produce new or enhanced products with features that render
the Company's  products  obsolete or less marketable.  The Company's  ability to
compete  successfully  will  depend on the  Company's  continuing  research  and
development of new and improved  products and on the Company's  ability to adapt
to technological changes and advances in its consumer products, in the treatment
of water  systems  and in  biorational  agricultural  products.  There can be no
assurance  that  the  Company  will  be  able  to  compete  successfully,   that
competitors will not develop  technologies or products that render the Company's
products  obsolete  or less  marketable,  or that  the  Company  will be able to
successfully enhance its products or develop new products.

         Government Regulation.  The Company's consumer,  water system treatment
and agricultural  products contain, or require the use of, various chemicals and
are therefore subject to various environmental  regulations and other applicable
laws.  Certain of the  Company's  consumer and water system  treatment  products
require the use of  chemicals  which are  classified  under  applicable  laws as
hazardous  substances.  The Company does not maintain insurance to compensate it
for any  liabilities  it may incur if it were to violate  environmental  laws or
regulations.  Although  the Company  does not believe it has  incurred  any such
liability to date, there can be no assurance that such environmental liabilities
will not be incurred in the future.  The use of certain  chemicals  contained in
the Company's  products is subject to  frequently  changing  federal,  state and
local laws and substantial regulation under these laws by governmental agencies,
including  the  United  States  Environmental  Protection  Agency  ("EPA"),  the
Occupational Health and Safety Administration, various state agencies and county
and local authorities  acting in conjunction with Federal and state authorities.
Among other things,  these regulatory bodies impose requirements to control air,
soil and water  pollution,  to protect  against  occupational  exposure  to such
chemicals, including health and safety risks, and to require notification of the
storage,  use and release of certain  hazardous  chemicals and  substances.  The
Company believes that it is in substantial compliance with all material federal,
state and local laws and regulations  governing its material business operations
and has obtained  all  material  licenses,  authorizations,  approvals,  orders,
certificates and permits  required for the operation of its business.  There can
be no  assurance  that the  Company  in the future  will be able to comply  with
current or future government  regulations in every jurisdiction in which it will
conduct  its  material   business   operations   without   substantial  cost  or
interruption of its operations,  or that any present or future federal, state or
local  environmental  protection  regulations  may not  restrict  the  Company's
current and possible future activities.  In the event that the Company is unable
to comply with such  requirements,  the Company could be subject to  substantial
sanctions, including restrictions on its business operations, monetary liability
and criminal  sanctions,  any of which could have a material adverse effect upon
the Company's business.

         Uncertainty of Widespread Market Acceptance of Consumer, Industrial and
Biorational Agricultural Products;  Limited Marketing Experience. The Company is
concentrating  its efforts on the sale of consumer and  industrial  water system
treatment products and biorational  agricultural products. To date, sales of its
municipal  and  industrial  water system  treatment  products have been limited.
Although  many of the  biorational  agricultural  products of the  Company  have
established market acceptance, some of them are relatively new and not yet

                                                       6

<PAGE>



universally accepted by consumers.  As is typical with new products,  demand and
market acceptance for the Company's industrial and new agricultural products are
subject to a high level of uncertainty.  Achieving  widespread market acceptance
for  these  products  will  require   substantial   marketing  efforts  and  the
expenditure of significant funds to create brand recognition and customer demand
for such products and to cause  potential  customers to consider the benefits of
the Company's  products as against the  traditional  products to which they have
been  accustomed.  There can be no assurance  that the  Company's  products will
achieve market acceptance or that sales of the Company's consumer and industrial
water system  treatment  and  biorational  agricultural  products  will generate
revenues sufficient to fund the Company' operations.

         Seasonality. Sales of the Company's agricultural products are seasonal,
with  strongest  sales  during  the first two  quarters  of the  calendar  year.
Additionally,  periods of  inclement  weather  can serve to delay  purchases  by
consumers of  agricultural  products.  Sales of the Pipe Klean and Well Klean II
products are also seasonal in those parts of the United States in the snow belt.
Such  seasonal or delayed  sales can result in uneven cash flow for the Company,
which may cause the  Company  to be  dependent  on cash  flows from sales of its
water system treatment  products during those portions of the year when sales of
agricultural  products  are slow and may  require  the  Company  to  obtain  and
maintain  short-term  financing  arrangements.   In  the  event  such  financing
arrangements  are not available or, once  acquired,  cease to be available,  the
Company's  operations  and financial  condition  could be  materially  adversely
affected.

         Limited Patent and Proprietary Information Protection.  The Company has
received a patent for the use of Eliminate  technology in cleaning potable water
distribution  systems.  The Company has several  patents  covering its automated
control  system for using the Company's  Eliminate  technology  for  controlling
scale and  corrosion  in water  cooling  systems and on its process for cleaning
water distribution  systems. The Company also has a patent for its multi-purpose
cleaning  formulation  which will be sold by HCP.  The  Company  has  received a
patent in respect  of Clean  Sweep.  Additionally,  the  Company  has two United
States patents  pending  related to the process for cleaning water  distribution
systems.  The Company  currently  is executing a foreign  patent  program on the
Company's basic United States patent technology.  There can be no assurance that
any patents will afford the Company commercially  significant  protection of its
technology  or that the  Company  will have  adequate  resources  to enforce its
patents.   The  Company  believes  that  it  has  independently   developed  its
proprietary  Eliminate  technology for controlling  scale and corrosion in water
distribution  systems and that its technology  does not infringe the proprietary
rights of others.  Although the Company has received no claims of  infringement,
it is possible that  infringement  of existing or future  patents or proprietary
rights may occur.  In the event that the Company's  products  infringe patent or
proprietary  rights of  others,  the  Company  may be  required  to  modify  its
processes or obtain a license.  There can be no assurance that the Company would
be able to do so in a timely manner,  upon acceptable terms and conditions or at
all. The failure to do so would have a material  adverse  effect on the Company.
In addition,  there can be no assurance that the Company will have the financial
or other  resources  necessary to defend a patent  infringement  or  proprietary
rights action.  Moreover,  if any of the Company's  products infringe patents or
propriety rights of others, the Company under certain circumstances could become
liable for damages which could have a material adverse effect on the Company.

         The  Company's  registered  trademarks  for its  consumer  products are
Eliminate,  Clean Sweep and  h.e.r.c.(R)  The Company also has the  Eliminate(R)
Man(C)  registered  as a copyright.  The  Company's  registered  trademarks  for
industrial  products  include some of the foregoing as well as Well Klean II and
Pipe Klean.  CCT's  registered  trademarks  for its  agricultural  products  are
Stressguard(R), COoBACIL(R), Coax(R), Deny(R), Line-Out(R) and Spark(R).

         The  Company  also  relies on  proprietary  know-how  and  confidential
information  and employs  various  methods to protect the  processes,  concepts,
ideas and documentation  associated with its technology.  However,  such methods
may not afford  complete  protection  and there can be no assurance  that others
will  not   independently   develop   such   processes,   concepts,   ideas  and
documentation.  Although  the  Company  requires  all of its  employees  to sign
confidentiality agreements,  there can be no assurance that such agreements will
be enforceable or will provide meaningful  protection to the Company.  There can
be no assurance  that the Company will be able to  adequately  protect its trade
secrets or that other  companies will not acquire  information  that the Company
considers to be  proprietary.  Moreover,  there can be no  assurance  that other
companies will not independently  develop know-how  comparable to or superior to
that of the Company.


                                                       7

          Product  Liability.  The Company is engaged in a business  which could
expose it to possible  claims for  personal  injury from the use of its consumer
and  industrial  products.  The Company  maintains  liability  insurance  in the
aggregate  amount  of  $2,000,000  with a  per-occurrence  limit of  $1,000,000.
Although  no claims have been made  against the Company or any of the  customers
using its  industrial  products  to date,  there can be no  assurance  that such
claims  will not arise in the  future  or that the  insurance  coverage  will be
sufficient to pay such claims.  A partially or completely  uninsured  claim,  if
successful and of significant magnitude, could have a material adverse effect on
the Company.

         Dependence  on Third Party  Suppliers  and  Manufacturers.  The Company
purchases  substantially  all of its  raw  chemical  supplies  and  agricultural
products  from third  parties.  The  Company  believes  that there are  numerous
available sources of supply.  While the Company attempts to maintain alternative
sources for the Company's supplies,  the Company is subject to the risk of price
fluctuations and possible delays in deliveries. Failure by suppliers to continue
to supply the Company on commercially  reasonable terms, or at all, would have a
material adverse effect on the Company.  The Company generally does not maintain
long-term  supply  agreements with its suppliers and purchases raw materials and
agricultural products pursuant to purchase orders or short-term contracts in the
ordinary  course  of  business.  Failure  or delay in  receiving  necessary  raw
materials and  agricultural  products by the Company would adversely  affect the
Company's operations and its ability in turn to deliver its products on a timely
basis.

         Dependence on Key Personnel. The success of the Company is dependent on
the  personal  efforts  of S.  Steven  Carl,  Chairman  of the  Board  and Chief
Executive Officer of the Company, Gary S. Glatter, President and Chief Operating
Officer of the Company,  Dr.  Jerome H. Ludwig,  Executive  Vice  President  and
Secretary  of the Company  and  Gilbert C.  Crowell,  Jr.,  President  and Chief
Operating  Officer of CCT, and certain other key  personnel.  The Company or CCT
has entered into  employment  agreements  with Messrs.  S. Steven Carl,  Gary S.
Glatter,  Dr. Jerome H. Ludwig and Gilbert C. Crowell, Jr. expiring in May 1999,
December 1998, May 1998 and May 1999,  respectively.  The loss of their services
could have a material  adverse  effect on the Company's  business and prospects.
The success of the Company is also dependent upon its ability to hire and retain
additional qualified marketing,  technical and financial personnel. There can be
no  assurance  that the Company  will be able to hire or retain  such  necessary
personnel in the future.

         No  Dividends.  The  Company has paid no cash  dividends  on its Common
Stock to date. Payment of dividends on the Common Stock is within the discretion
of the Board of  Directors  and will depend  upon the  Company's  earnings,  its
capital  requirements and financial  condition,  and other relevant factors. The
Company does not  currently  intend to declare any dividends on its Common Stock
in the foreseeable future.

         Authorization  and  Discretionary  Issuance  of  Preferred  Stock.  The
Certificate of  Incorporation  of the Company  authorizes the issuance of "blank
check" preferred stock with such designations,  rights and preferences as may be
determined from time to time by the Board of Directors.  Accordingly,  the Board
of Directors is empowered,  without  stockholder  approval,  to issue  preferred
stock with dividend, liquidation, conversion, voting or other rights which could
adversely  affect the voting  power or other rights of the holders of the Common
Stock. In the event of issuance,  the preferred  stock could be utilized,  under
certain  circumstances,  as a method of  discouraging,  delaying or preventing a
change in control of the Company.  Although the Company has no present intention
to issue any shares of its preferred  stock,  there can be no assurance that the
Company will not do so in the future.

         Possible  Volatility of Market Price;  Limited  Public Market  Trading.
From time to time the market  prices of certain  chemical and  consumer  product
companies have been affected by various factors,  including  adverse  publicity.
There can be no assurance  that the market price of the Common Stock will not be
volatile  as a  result  of  factors  such as the  Company's  financial  results,
possible  adverse  publicity  resulting  from any  infractions  of  governmental
regulations  and various  other  factors  affecting  the  chemical  and consumer
product industries or the market generally. In recent years the stock market has
experienced  wide price  fluctuations  not necessarily  related to the operating
performance of such companies.  Although the Common Stock has been listed on The
Nasdaq SmallCap Market since May 1994,  there can be no assurance that a regular
trading market will be sustained.  Further, in order to continue to trade on The
Nasdaq  SmallCap  Market,  the Company  must meet The Nasdaq  SmallCap  Market's
standards for continued  listing.  If, at any time,  the Company's  Common Stock
were de-listed

                                                       8

<PAGE>



from The Nasdaq SmallCap Market,  the Company's  securities would become subject
to the "penny stock rules" applicable to non-Nasdaq companies whose common stock
trades at less than  $5.00 per share or which  have  tangible  net worth of less
than $5,000,000  ($2,000,000 if the Company has been operating for three or more
years).  Such rules require,  among other things,  that brokers who trade "penny
stock"  to  persons  other  than   "established   customers"   complete  certain
documentation,  make  suitability  inquiries of investors and provide  investors
with certain  information  concerning trading in the security,  including a risk
disclosure  document and quote  information  under certain  circumstances.  Many
brokers have decided not to trade "penny stock" because of the  requirements  of
the penny stock rules and, as a result, the number of broker-dealers  willing to
act as market makers in such securities is limited.

   
         Effect of  Outstanding  Warrants  and  Options.  In addition to the PHD
Warrants,  the Company  currently  has  outstanding  the  following  options and
warrants:  (i) warrants to purchase an  aggregate of 3,214,902  shares of Common
Stock at $2.00 per share,  (ii) an option to purchase  321,490 units,  each unit
consisting of one share of Common Stock and one warrant to purchase one share of
Common  Stock at $2.00  per  share,  issued  to GKN in  connection  with a prior
private  placement  in April 1996,  (iii)  warrants to purchase an  aggregate of
100,000 shares of Common Stock at $5.00 per share,  (iv) warrants to purchase an
aggregate  of 130,000  shares of Common  Stock at $6.50 per share  issued to the
underwriter of the Company's  initial public offering,  (v) warrants to purchase
546,500  shares of Common Stock at prices ranging from $2.00 to $2.75 per share,
(vi) options to purchase  345,000 shares of Common Stock granted and outstanding
under the Stock  Option Plan at  exercises  prices  ranging from $1.88 to $5.00,
(vii) options to purchase 422,000 shares of Common Stock granted and outstanding
under the 1996 Performance  Equity Plan at exercise prices ranging from $1.75 to
$2.38 per share,  and (viii) other options to purchase  790,000 shares of Common
Stock at prices  ranging  from  $1.50 to $4.00 per share.  All of the  foregoing
securities  (exercisable into an aggregate of 6,191,382 shares of Common Stock),
represent  the right to  acquire  Common  Stock of the  Company  during  various
periods of time and at various prices.  Holders of the foregoing  securities are
given the  opportunity  to profit from a rise in the market  price of the Common
Stock and are likely to  exercise  their  securities  at a time when the Company
would be able to obtain additional equity capital on more favorable terms. Thus,
the terms  upon  which the  Company  will be able to  obtain  additional  equity
capital may be adversely  affected since the holders of outstanding  options and
warrants can be expected to exercise them at a time when the Company  would,  in
all likelihood,  be able to obtain any needed capital on terms more favorable to
the Company than the exercise terms provided by such outstanding securities.
    

         Control  by  Current  Stockholders.  Shelby A. Carl  beneficially  owns
743,655 shares,  or  approximately  11.3%,  of the outstanding  shares of Common
Stock  prior to this  offering,  and S. Steven Carl  beneficially  owns  829,851
shares, or approximately  12.3% of the outstanding  shares Common Stock prior to
this  offering,  and together  they  beneficially  own an aggregate of 1,573,506
shares, or approximately  22.7% of the outstanding  shares of Common Stock prior
to this  offering.  Accordingly,  they are able to influence  substantially  the
election of the Company's directors,  increases in the authorized capital or the
dissolution, merger or sale of the assets of the Company and otherwise influence
the  affairs  of the  Company.  Moreover,  additional  shares may be issued to a
family  trust  created  by  Shelby  A.  Carl and to S.  Steven  Carl as  further
consideration in connection with the acquisition of CCT.


                                 USE OF PROCEEDS

   
         All  1,938,631  Shares  offered  hereby  are being  registered  for the
account of the Selling  Stockholders.  The  Company  will not receive any of the
proceeds from the sale of the Shares.  However,  of the 1,938,631 Shares offered
hereby,  335,000 Shares are issuable upon exercise of certain warrants. If these
warrants  are fully  exercised,  the Company  will receive up to an aggregate of
$892,500 in gross  proceeds.  The  Company is unable to  estimate  the number of
warrants  that may be exercised.  The Company  believes that the exercise of the
warrants  primarily  will be  dependent on the market price of a share of Common
Stock at the time of  exercise  and its  relation to their  respective  exercise
prices. See "Selling Stockholders."

         The Company intends to use the net proceeds from the exercise of any of
the  warrants  for  working  capital  and general  corporate  purposes.  Pending
application  of the  proceeds,  the  Company  intends  to  place  the  funds  in
interest-bearing investments such as bank accounts,  certificates of deposit and
United States government obligations.

     The  registration  rights  granted to certain of the  Selling  Stockholders
generally provide that the Company and the Selling  Stockholders  indemnify each
other against certain  liabilities,  including  liabilities under the Securities
Act. In the opinion of the Commission,  such  indemnification  is against public
policy and is, therefore unenforceable. See "Indemnification."


                              PLAN OF DISTRIBUTION

   
         The Selling  Stockholders  have  advised the Company  that sales of the
Shares may be  effected  from time to time in  transactions  (which may  include
block  transactions) on the Nasdaq SmallCap Market or the Boston Stock Exchange,
in negotiated  transactions,  or a combination of such methods of sale, at fixed
prices which may be changed, at market prices prevailing at the time of sale, or
at negotiated  prices.  The Selling  Stockholders  have advised the Company that
they have not entered into any agreements,  understandings  or arrangements with
any underwriters or broker-dealers  regarding the sale of their Shares.  Because
each of the Selling Stockholders  invested in the Company through PHD, it may be
expected  that the Shares  will be sold to PHD as  principal  or through  PHD as
agent.  The  Selling  Stockholders  also  may  sell  their  Shares  directly  to
purchasers or to or through other broker-dealers (including GKN) hich may act as
agents or principals. PD and such broker-dealers may receive compensation in the
form of discounts,  concessions,  or commissions  from the Selling  Stockholders
and/or the  purchasers of the Shares for whom they act as agents or to whom they
sell as principal,  or both (which  compensation might be in excess of customary
commissions). The Selling Stockholder, PHD or any other broker- dealer that acts
in connection  with a sale of the Shares might be deemed to be an  "underwriter"
within the meaning of Section 2(11) of the  Securities  Act. Each of the Selling
Stockholders and any  broker-dealers  that is participating in a distribution is
obligated to comply with certain rules promulgated by the Commission designed to
prevent  manipulative and deceptive  practices,  including Rules 10b-6 and 10b-7
promulgated  under the  Exchange  Act.  Under these  rules,  such persons may be
prevented from engaging in any market-making  activities or solicited  brokerage
activities  with regard to the Company's  securities  during certain  prescribed
periods. A Selling  Stockholder may agree to indemnify PHD or any agent,  dealer
or  broker-dealer  that  participates in transactions  involving the sale of the
Shares against  certain  liabilities,  including  liabilities  arising under the
Securities Act.
    

         The Company  has agreed to keep the  Registration  Statement,  of which
this  Prospectus is a part,  effective  until the earlier of the sale of all the
Shares or all the Shares may be sold by the holders thereof under Rule 144.


                                  LEGAL MATTERS

         Certain  matters  with respect to the legality of the issuance and sale
of the Shares  offered  hereby  will be passed  upon for the Company by Graubard
Mollen & Miller, New York, New York.


                                     EXPERTS

         The financial  statements  incorporated by reference in this Prospectus
have been audited by BDO Seidman, LLP, independent certified public accountants,

                                 INDEMNIFICATION

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors,  officers and controlling  persons of
the Company  pursuant to the  provisions  described  above,  or  otherwise,  the
Company  has  been  advised  that  in  the  opinion  of  the   Commission   such
indemnification  is against public policy as expressed in the Securities Act and
is  therefore  unenforceable.  In the  event  that a claim  for  indemnification
against such  liabilities is asserted by such  director,  officer or controlling
person in  connection  with the  registration  of the Shares,  the Company will,
unless in the opinion of its counsel the matter has been settled by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification  by it is  against  public  policy  as  expressed  in  the
Securities Act and will be governed by the final adjudication of such issue.

Item 15. Indemnification of Directors and Officers.

     The Company's  Certificate  of  Incorporation  provides that all directors,
officers,  employees  and  agents  of the  Registrant  shall be  entitled  to be
indemnified  by  the  Company  to the  fullest  extent  permitted  by  law.  The
Certificate of Incorporation also provides as follows:

                  A  director,  or former  director,  shall not be liable to the
         corporation  or to any of its  stockholders  for  monetary  damages for
         breach of fiduciary  duty as a director,  provided that this  provision
         shall not eliminate or limit the  liability of a director:  (i) for any
         breach of the  director's  duty of  loyalty to the  corporation  or its
         stockholders;  for acts or omissions not in good faith or which involve
         intentional  misconduct or a knowing  violation of law; under ss.174 of
         the General Corporation Law of the State of Delaware, pertaining to the
         liability  of directors  for unlawful  payment of dividends or unlawful
         stock purchase or redemption;  or (ii) for any  transaction  from which
         the director derived an improper personal benefit.

         Section  145  of  the  Delaware  General   Corporation  Law  concerning
indemnification of officers, directors, employees and agents is set forth below.

     "Section 145. Indemnification of officers, directors, employees and agents;
insurance.

         (a) A corporation  may indemnify any person who was or is a party or is
threatened to be made a party to any  threatened,  pending or completed  action,
suit or proceeding,  whether civil,  criminal,  administrative  or investigative
(other  than an action by or in the right of the  corporation)  by reason of the
fact  that  he  is or  was  a  director,  officer,  employee  or  agent  of  the
corporation,  or is or was  serving  at the  request  of  the  corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other  enterprise,  against  expenses  (including  attorneys'
fees),  judgments,  fines and amounts paid in settlement actually and reasonably
incurred by him in connection  with such action,  suit or proceeding if he acted
in good faith and in a manner he reasonably  believed to be in or not opposed to
the best interests of the corporation,  and, with respect to any criminal action
or proceeding,  had no reasonable cause to believe his conduct was unlawful. The
termination of any action,  suit or proceeding by judgment,  order,  settlement,
conviction,  or upon a plea of nolo contendere or its equivalent,  shall not, of
itself,  create a presumption that the person did not act in good faith and in a
manner  which  he  reasonably  believed  to be in or not  opposed  to  the  best
interests  of the  corporation,  and with  respect  to any  criminal  action  or
proceeding, had reasonable cause to believe that his conduct was unlawful.

         (b) A corporation  may indemnify any person who was or is a party or is
threatened to be made a party to any threatened,  pending or completed action or
suit by or in the right of the  corporation  to procure a judgement in its favor
by reason of the fact that he is or was a director,  officer,  employee or agent
of the corporation, or is

                         II-1

<PAGE>



or was  serving  at the  request  of the  corporation  as a  director,  officer,
employee or agent of another corporation,  partnership,  joint venture, trust or
other  enterprise  against  expenses  (including  attorneys'  fees) actually and
reasonably  incurred by him in connection with the defense or settlement of such
action or suit if he acted in good faith and in a manner he reasonably  believed
to be in or not opposed to the best interests of the corporation and except that
no indemnification  shall be made in respect of any claim, issue or matter as to
which such  person  shall have been  adjudged  to be liable  for  negligence  or
misconduct in the performance of his duty to the corporation  unless and only to
the extent  that the Court of Chancery or the court in which such action or suit
was brought shall determine upon application  that,  despite the adjudication of
liability  but in view of all the  circumstances  of the  case,  such  person is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court shall deem proper.

         (c) To the extent  that a  director,  officer,  employee  or agent of a
corporation  has been  successful  on the merits or  otherwise in defense of any
action,  suit  or  proceeding  referred  to in  subsections  (a) and (b) of this
section,  or in  defense  of any  claim,  issue or matter  therein,  he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

         (d) Any  indemnification  under  sections  (a) and (b) of this  section
(unless ordered by a court) shall be made by the corporation  only as authorized
in the specific case upon a determination that  indemnification of the director,
officer, employee or agent is proper in the circumstances because he has met the
applicable  standard  of conduct  set forth in  subsections  (a) and (b) of this
section.  Such  determination  shall be made (1) by the board of  directors by a
majority  vote of a quorum  consisting of directors who were not parties to such
action, suit or proceeding, or (2) if such a quorum is not obtainable,  or, even
if obtainable,  a quorum of disinterested  directors so directs,  by independent
legal counsel in a written opinion, or (3) by the stockholders.

         (e) Expenses incurred by an officer or director in defending a civil or
criminal  action,  suite or proceeding may be paid by the corporation in advance
of the final  disposition of such action,  suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer, to repay such amount if
it shall  ultimately be determined  that he is not entitled to be indemnified by
the corporation as authorized in this section.  Such expenses  incurred by other
employees and agents may be so paid upon such terms and  conditions,  if any, as
the board of directors deems appropriate.

         (f) The  indemnification  and  advancement of expenses  provided by, or
granted  pursuant to, the other  subsections of this section shall not be deemed
exclusive  of any  other  rights  to  which  those  seeking  indemnification  or
advancement  of expenses  may be entitled  under any bylaw,  agreement,  vote of
stockholders or disinterested  directors or otherwise,  both as to action in his
official  capacity  and as to action in  another  capacity  while  holding  such
office.

         (g) A corporation  shall have power to purchase and maintain  insurance
on behalf of any person who is or was  director,  officer,  employee or agent of
the  corporation,  or is or was serving at the request of the  corporation  as a
director, officer, employee or agent of another corporation,  partnership, joint
venture,  trust or other enterprise  against any liability  asserted against him
and incurred by him in any such capacity,  or arising out of his status as such,
whether or not the  corporation  would have the power to  indemnify  him against
such liability under this section.

         (h) For purposes of this section, references to "the corporation" shall
include, in addition to the resulting corporation,  any constituent  corporation
(including  any  constituent of a constituent)  absorbed in a  consolidation  or
merger which, if its separate existence had continued,  would have had power and
authority to indemnify its directors, officers, and employees or agents, so that
any  person  who is or was a  director,  officer,  employee  or  agent  of  such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director,  officer,  employee or agent of another  corporation,
partnership,  joint venture, trust or other enterprise,  shall stand in the same
position  under  this  section  with  respect  to  the  resulting  or  surviving
corporation as he would have with respect to such constituent corporation if its
separate existence had continued.

         (i) For purposes of this  section,  references  to "other  enterprises"
shall include  employee  benefit plans;  references to "fines" shall include any
excise taxes assessed on a person with respect to an employee benefit plan;

                         II-2

<PAGE>



and references to "serving at the request of the corporation"  shall include any
service as a  director,  officer,  employee  or agent of the  corporation  which
imposes duties on, or involves services by, such director,  officer, employee or
agent  with  respect  to  an  employee   benefit  plan,  its   participants   or
beneficiaries; and a person who acted in good faith an in a manner he reasonably
believed  to be in the  interest of the  participants  and  beneficiaries  of an
employee  benefit plan shall be deemed to have acted in a manner "not opposed to
the best interests of the corporation" as referred to in this section.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the  "Securities  Act"), may be permitted to directors,
officers,  and  controlling  persons of the Company  pursuant  to the  foregoing
provisions,  or  otherwise,  the Company has been advised that in the opinion of
the Securities and Exchange  Commission such  indemnification  is against public
policy as expressed in the Securities Act and is, therefore,  unenforceable.  In
the event that a claim for indemnification  against such liabilities (other than
the payment by the Company of expenses  incurred or paid by a director,  officer
or controlling person of the Company in a successful defense of any action, suit
or proceeding) is asserted by such  director,  officer or controlling  person in
connection with the securities being registered, the Company will, unless in the
opinion of its counsel  the matter has been  settled by  controlling  precedent,
submit  to the court of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against  public policy as expressed in the  Securities
Act and will be governed by the final adjudication of such issue.

         Pursuant to the Agency Agreement between the Company and Perrin, Holden
& Davenport Capital Corp.  ("PHD"),  the placement agent for certain  securities
described  in this  Registration  Statement  and included as Exhibit 4.4 to this
Registration   Statement,   the  officers  and  directors  of  the  Company  are
indemnified by PHD and PHD and controlling persons of PHD are indemnified by the
Company, against certain civil liabilities under the Securities Act.

Item 17. Undertakings.

         (a)      The undersigned Registrant hereby undertakes:

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

          (i)  To include any  prospectus  required  by Section  10(a)(3) of the
               Securities Act of 1933;

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

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

Provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
Registration  Statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic  reports filed by the  Registrant  pursuant to Section 13(a) or Section
15(d) of the Securities  Exchange Act of 1934 that are incorporated by reference
in the Registration Statement.

                  (2) That, for the purpose of determining  any liability  under
the Securities Act of 1933, each such  post-effective  amendment shall be deemed
to be a new registration  statement  relating to the securities offered therein,
and the  offering  of such  securities  at that  time  shall be deemed to be the
initial bona fide offering thereof.


                         II-4

<PAGE>



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

         (b) The undersigned  Registrant hereby undertakes that, for purposes of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to Section  13(a) or Section 15(d) of the
Securities  Exchange  Act of 1934  (and  where  applicable,  each  filing  of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
Registration  Statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (c)  Insofar  as  indemnification  for  liabilities  arising  under the
Securities Act of 1933 may be permitted to directors,  officers and  controlling
persons of the Registrant  pursuant to the foregoing  provisions,  or otherwise,
the  Registrant  has been  advised  that in the  opinion of the  Securities  and
Exchange  Commission such  indemnification is against public policy as expressed
in the Act and is,  therefore,  unenforceable.  In the  event  that a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses  incurred or paid by a director,  officer or  controlling
person of the  Registrant  in the  successful  defense  of any  action,  suit or
proceeding)  is  asserted by such  director,  officer or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

 THE REGISTERED HOLDER OF THIS WARRANT, BY ITS ACCEPTANCE HEREOF, AGREES THAT IT
                        WILL NOT SELL, TRANSFER OR ASSIGN
                     THIS WARRANT EXCEPT AS HEREIN PROVIDED.

              VOID AFTER 5:00 P.M. EASTERN TIME, NOVEMBER 19, 2001

                                     WARRANT

                               For the Purchase of

                         200,000 Shares of Common Stock
                                       of
                         H.E.R.C. PRODUCTS INCORPORATED


     1.    Warrant.

         THIS  CERTIFIES  THAT,  in  consideration  of  services  to be provided
pursuant to the  Financial  Advisory  and  Investment  Banking  Agreement  dated
November 19, 1996 ("Advisory Agreement") by GKN Securities Corp. ("Holder"),  as
registered owner of this Warrant, to H.E.R.C. Products Incorporated ("Company"),
Holder is  entitled,  at any time or from time to time at or after  November 19,
1997  ("Commencement  Date"),  and at or before 5:00 p.m., Eastern Time November
19, 2001 ("Expiration Date"), but not thereafter, to subscribe for, purchase and
receive,  in whole or in part, up to two hundred  thousand  (200,000)  shares of
Common Stock of the Company, $.01 par value ("Common Stock"); provided, however,
if the Advisory  Agreement is terminated in accordance with Section 2 thereof by
the  Company,  then the number of shares of Common Stock that the Holder will be
able to subscribe for, purchase and receive hereunder, will be up to one hundred
thousand  (100,000)  shares of Common Stock.  If the Expiration Date is a day on
which banking institutions are authorized by law to close, then this Warrant may
be exercised on the next  succeeding  day which is not such a day in  accordance
with the terms herein.  During the period  ending on the  Expiration  Date,  the
Company  agrees not to take any action that would  terminate  the Warrant.  This
Warrant is initially  exercisable at $2.50 per share of Common Stock  purchased;
provided,  however,  that upon the occurrence of any of the events  specified in
Section 6 hereof,  the rights  granted by this  Warrant,  including the exercise
price  and the  number  of  shares  of  Common  Stock to be  received  upon such
exercise,  shall be adjusted as therein  specified.  The term  "Exercise  Price"
shall mean the initial exercise price or the adjusted exercise price,  depending
on the context, of a share of Common Stock. The term "Securities" shall mean the
shares of Common Stock issuable upon exercise of this Warrant.

       2.  Exercise.

          2.1     Exercise Form. In order to exercise this Warrant, the exercise
form  attached  hereto must be duly  executed and completed and delivered to the
Company,  together  with this Warrant and payment of the Exercise  Price for the
Securities being purchased.  If the subscription rights represented hereby shall
not be exercised at or before 5:00 p.m.,  Eastern time, on the Expiration  Date,
this Warrant shall become and be void without  further force or effect,  and all
rights represented hereby shall cease and expire.

          2.2    Legend.  Each certificate for Securities  purchased under this
Warrant  shall  bear a legend  as  follows,  unless  such  Securities  have been
registered under the Securities Act of 1933, as amended ("Act"):

         "The  securities   represented  by  this   certificate  have  not  been
         registered  under the  Securities  Act of 1933,  as amended  ("Act") or
         applicable  state law. The securities 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 and applicable state law."

3.         Transfer.

       3.1        General  Restrictions.  The registered Holder of this Warrant,
by its acceptance  hereof,  agrees that it will not sell,  transfer or assign or
hypothecate  this Warrant to anyone except upon compliance  with, or pursuant to
exemptions  from,  applicable  securities  laws.  In order to make any permitted
assignment,  the Holder must deliver to the Company the assignment form attached
hereto duly  executed and  completed,  together with this Warrant and payment of
all transfer taxes, if any, payable in connection  therewith.  The Company shall
immediately  transfer this Warrant on the books of the Company and shall execute
and  deliver  a new  Warrant  or  Warrants  of  like  tenor  to the  appropriate
assignee(s)  expressly  evidencing the right to purchase the aggregate number of
shares of Common Stock  purchasable  hereunder or such portion of such number as
shall be contemplated by any such assignment.

       3.2      Restrictions  Imposed by the Securities  Act. This Warrant and
the Securities underlying this Warrant shall not be transferred unless and until
(i) the  Company  has  received  the opinion of counsel for the Holder that such
securities may be sold pursuant to an exemption from registration under the Act,
and  applicable  state law,  the  availability  of which is  established  to the
reasonable  satisfaction  of  the  Company,  or  (ii) a  registration  statement
relating to such Securities has been filed by the Company and declared effective
by the Securities and Exchange  Commission and compliance with applicable  state
law.

4.         New Warrants to be Issued.

     4.1         Partial  Exercise or Transfer.  Subject to the restrictions in
Section 3 hereof, this Warrant may be exercised or assigned in whole or in part.
In the event of the exercise or assignment  hereof in part only,  upon surrender
of this Warrant for  cancellation,  together with the duly executed  exercise or
assignment  form and  funds (or  conversion  equivalent)  sufficient  to pay any
Exercise  Price and/or  transfer tax, the Company shall cause to be delivered to
the Holder  without  charge a new  Warrant of like tenor to this  Warrant in the
name of the Holder  evidencing the right of the Holder to purchase the aggregate
number of shares of Common Stock and Warrants purchasable  hereunder as to which
this Warrant has not been exercised or assigned.

      4.2        Lost  Certificate.  Upon  receipt by the  Company of  evidence
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant
and of reasonably  satisfactory  indemnification,  the Company shall execute and
deliver a new Warrant of like tenor and date. Any such new Warrant  executed and
delivered  as a result of such loss,  theft,  mutilation  or  destruction  shall
constitute a substitute contractual obligation on the part of the Company.

5.         Registration Rights.

     5.1       "Piggy-Back" Registration.

     5.1.1 Grant of Right.  The Holders of this Warrant shall have the right for
a period of seven years from the Commencement Date to include all or any part of
this   Warrant  and  the  shares  of  Common  Stock   underlying   this  Warrant
(collectively,  the  "Registrable  Securities")  as part of any  registration of
securities  filed by the Company  (other than in  connection  with a transaction
contemplated by Rule 145(a) promulgated under the Act or pursuant to Form S-8 or
any equivalent form); provided,  however, that if, in the written opinion of the
Company's managing  underwriter or underwriters,  if any, for such offering (the
"Underwriter"),  the inclusion of the Registrable Securities,  when added to the
securities being registered by the Company or the selling  stockholder(s),  will
exceed the maximum amount of the Company's  securities which can be marketed (i)
at a price  reasonably  related  to their then  current  market  value,  or (ii)
without  materially  and adversely  affecting the entire  offering,  the Company
shall  nevertheless  register all or any portion of the  Registrable  Securities
required to be so registered but such  Registrable  Securities shall not be sold
by the Holders until 90 days after the registration  statement for such offering
has  become  effective;  and  provided  further  that,  if  any  securities  are
registered  for sale on behalf of other  stockholders  in such offering and such
stockholders  have not agreed to defer such sale until the expiration of such 90
day period,  the number of  securities  to be sold by all  stockholders  in such
public  offering  during such 90 day period shall be apportioned  pro rata among
all  such  selling  stockholders,  including  all  holders  of  the  Registrable
Securities,  according to the total amount of securities of the Company proposed
to  be  sold  by  said  selling  stockholders,  including  all  holders  of  the
Registrable Securities.

                                                       2

<PAGE>



     5.1.2  Terms.  The Company  shall bear all fees and  expenses  attendant to
registering  the Registrable  Securities,  but the Holders shall pay any and all
underwriting  commissions and the expenses of any legal counsel  selected by the
Holders  to  represent  them in  connection  with  the  sale of the  Registrable
Securities.  In the event of such a proposed  registration,  the  Company  shall
furnish the then Holders of  outstanding  Registrable  Securities  with not less
than thirty days written  notice  prior to the  proposed  date of filing of such
registration  statement.  Such notice to the Holders shall  continue to be given
for each  registration  statement filed by the Company until such time as all of
the  Registrable  Securities  have been sold by the  Holder.  The holders of the
Registrable  Securities  shall  exercise the  "piggy-back"  rights  provided for
herein by giving  written  notice,  within  twenty  days of the  receipt  of the
Company's notice of its intention to file a registration statement.  The Company
shall cause any registration  statement filed pursuant to the above  "piggyback"
rights to  remain  effective  for at least  nine  months  from the date that the
Holders of the  Registrable  Securities are first given the  opportunity to sell
all of such securities.  Nothing contained in this Warrant shall be construed as
requiring  any Holder to exercise  this Warrant or any part thereof prior to the
initial filing of any registration statement or the effectiveness thereof.

   5.2         General Terms

      5.2.1     Indemnification.

     (a) The Company shall indemnify the Holder(s) of the Registrable Securities
to be sold pursuant to any registration  statement hereunder and any underwriter
or person deemed to be an underwriter under the Act and each person, if any, who
controls  such  Holders or  underwriters  or persons  deemed to be  underwriters
within the meaning of Section 15 of the Act or Section  20(a) of the  Securities
Exchange Act of 1934,  as amended  ("Exchange  Act"),  against all loss,  claim,
damage, expense or liability (including all reasonable attorneys' fees and other
expenses  reasonably  incurred in investigating,  preparing or defending against
any claim whatsoever) to which any of them may become subject under the Act, the
Exchange  Act or  otherwise,  arising  from  such  registration  statement.  The
Holder(s) of the Registrable Securities to be sold pursuant to such registration
statement,  and their successors and assigns, shall severally,  and not jointly,
indemnify the Company,  against all loss,  claim,  damage,  expense or liability
(including all  reasonable  attorneys'  fees and other expenses  reasonably
incurred in investigating,  preparing or defending against any claim whatsoever)
to which they may become  subject  under the Act, the Exchange Act or otherwise,
arising from information  furnished by or on behalf of such Holders, in writing,
for specific inclusion in such registration statement.

     (b) If any action is brought against a party hereto,  ("Indemnified Party")
in  respect  of  which   indemnity  may  be  sought   against  the  other  party
("Indemnifying   Party"),   such   Indemnified   Party  shall  promptly   notify
Indemnifying Party in writing of the institution of such action and Indemnifying
Party shall assume the defense of such action, including the employment and fees
of counsel  reasonably  satisfactory to the Indemnified  Party. Such Indemnified
Party  shall have the right to employ its or their own counsel in any such case,
but the fees and  expenses  of such  counsel  shall  be at the  expense  of such
Indemnified  Party unless (i) the  employment  of such  counsel  shall have been
authorized in writing by  Indemnifying  Party in connection  with the defense of
such  action,  or (ii)  Indemnifying  Party shall not have  employed  counsel to
defend such action,  or (iii) such Indemnified  Party shall have been advised by
counsel that there may be one or more legal  defenses  available to it which may
result in a conflict between the Indemnified  Party and  Indemnifying  Party (in
which case Indemnifying  Party shall not have the right to direct the defense of
such action on behalf of the  Indemnified  Party),  in any of which events,  the
reasonable  fees and expenses of not more than one additional  firm of attorneys
designated in writing by the  Indemnified  Party shall be borne by  Indemnifying
Party. Notwithstanding anything to the contrary contained herein, if Indemnified
Party shall  assume the defense of such action as provided  above,  Indemnifying
Party shall not be liable for any settlement of any such action effected without
its written consent.

     (c) If the  indemnification  or  reimbursement  provided  for  hereunder is
finally  judicially  determined  by a  court  of  competent  jurisdiction  to be
unavailable  to an  Indemnified  Party (other than as a  consequence  of a final
judicial  determination of willful misconduct,  bad faith or gross negligence of
such Indemnified Party), then Indemnifying Party agrees, in lieu of indemnifying
such  Indemnified  Party,  to  contribute  to the amount paid or payable by such
Indemnified  Party (i) in such  proportion  as is  appropriate  to  reflect  the
relative benefits received,  or sought to be received,  by Indemnifying Party on
the one hand and by such Indemnified Party on the other or (ii) if (but only if)
the allocation provided in clause (i) of this sentence is not permitted by

                                                       3

<PAGE>



applicable  law, in such  proportion as is  appropriate  to reflect not only the
relative  benefits referred to in such clause (i) but also the relative fault of
Indemnifying Party and of such Indemnified Party; provided,  however, that in no
event shall the aggregate amount  contributed by a Holder exceed the profit,  if
any,  earned by such Holder as a result of the  exercise by him of the  Warrants
and the sale by him of the underlying shares of Common Stock.

     (d) The  rights  accorded  to  Indemnified  Parties  hereunder  shall be in
addition  to any rights  that any  Indemnified  Party may have at common law, by
separate agreement or otherwise.

     5.2.2  Exercise of Warrants.  Nothing  contained  in this Warrant  shall be
construed as requiring  the  Holder(s) to exercise  their  Warrants  prior to or
after the initial  filing of any  registration  statement  or the  effectiveness
thereof.

     5.2.3  Documents  Delivered to Holders.  The Company  shall furnish to each
Holder  participating in any of the foregoing  offerings and to each Underwriter
of any such offering, if any, a signed counterpart,  addressed to such Holder or
Underwriter,  of (i) an opinion of counsel to the Company,  dated the  effective
date of such  registration  statement  (and,  if such  registration  includes an
underwritten public offering, an opinion dated the date of the closing under any
underwriting  agreement related thereto), and (ii) a "cold comfort" letter dated
the effective date of such  registration  statement  (and, if such  registration
includes an underwritten public offering, a letter dated the date of the closing
under the underwriting  agreement) signed by the independent  public accountants
who have issued a report on the Company's financial  statements included in such
registration  statement,  in each case covering  substantially  the same matters
with  respect  to such  registration  statement  (and  the  prospectus  included
therein) and, in the case of such  accountants'  letter,  with respect to events
subsequent to the date of such financial statements,  as are customarily covered
in  opinions  of  issuer's  counsel and in  accountants'  letters  delivered  to
underwriters in underwritten  public offerings of securities.  The Company shall
also deliver promptly to each Holder  participating  in the offering  requesting
the correspondence and memoranda described below and to the managing underwriter
copies of all correspondence between the Commission and the Company, its counsel
or auditors and all memoranda relating to discussions with the Commission or its
staff with  respect to the  registration  statement  and permit  each Holder and
underwriter to do such  investigation,  upon  reasonable  advance  notice,  with
respect to information  contained in or omitted from the registration  statement
as it deems  reasonably  necessary to comply with applicable  securities laws or
rules of the NASD. Such investigation shall include access to books, records and
properties  and  opportunities  to discuss the  business of the Company with its
officers and independent  auditors,  all to such  reasonable  extent and at such
reasonable times and as often as any such Holder shall reasonably request.

6.         Adjustments

     6.1  Adjustments to Exercise  Price and Number of Securities.  The Exercise
Price and the number of shares of Common Stock  underlying this Warrant shall be
subject to adjustment from time to time as hereinafter set forth:

     6.1.1 Stock Dividends - Recapitalization,  Reclassification, Split-Ups. If,
after the date hereof,  and subject to the provisions of Section 6.2 below,  the
number of outstanding shares of Common Stock is increased by a stock dividend on
the  Common  Stock  payable  in  shares  of  Common  Stock  or  by  a  split-up,
recapitalization  or reclassification of shares of Common Stock or other similar
event, then, on the effective date thereof, the number of shares of Common Stock
issuable on exercise of this Warrant  shall be increased in  proportion  to such
increase in outstanding shares.

     6.1.2 Aggregation of Shares.  If after the date hereof,  and subject to the
provisions of Section 6.3, the number of  outstanding  shares of Common Stock is
decreased  by a  consolidation,  combination  or  reclassification  of shares of
Common Stock or other similar event, then, upon the effective date thereof,  the
number of shares of Common Stock  issuable on exercise of this Warrant  shall be
decreased in proportion to such decrease in outstanding shares.

     6.1.3  Adjustments  in  Exercise  Price.  Whenever  the number of shares of
Common Stock  purchasable  upon the  exercise of this  Warrant is  adjusted,  as
provided in this  Section  6.1,  the  Exercise  Price shall be adjusted  (to the
nearest cent) by  multiplying  such  Exercise  Price  immediately  prior to such
adjustment by a
                                                       4

<PAGE>



fraction  (x) the  numerator  of which  shall be the  number of shares of Common
Stock  purchasable upon the exercise of this Warrant  immediately  prior to such
adjustment,  and (y) the  denominator  of which shall be the number of shares of
Common Stock so purchasable immediately thereafter.

     6.1.4  Replacement of Securities upon  Reorganization,  etc. In case of any
reclassification  or  reorganization  of the outstanding  shares of Common Stock
other than a change  covered by Section 6.1.1 hereof or which solely affects the
par  value of such  shares  of  Common  Stock,  or in the case of any  merger or
consolidation  of the Company  with or into  another  corporation  (other than a
consolidation  or merger in which the Company is the continuing  corporation and
which  does  not  result  in  any  reclassification  or  reorganization  of  the
outstanding shares of Common Stock), or in the case of any sale or conveyance to
another  corporation  or entity of the property of the Company as an entirety or
substantially  as an entirety in connection with which the Company is dissolved,
the Holder of this Warrant shall have the right thereafter (until the expiration
of the right of exercise of this  Warrant) to receive upon the exercise  hereof,
for the same aggregate  Exercise Price payable  hereunder  immediately  prior to
such  event,  the kind and  amount  of shares  of stock or other  securities  or
property (including cash) receivable upon such reclassification, reorganization,
merger or consolidation,  or upon a dissolution following any such sale or other
transfer,  by a Holder of the  number of shares of Common  Stock of the  Company
obtainable upon exercise of this Warrant immediately prior to such event; and if
any reclassification  also results in a change in shares of Common Stock covered
by  Sections  6.1.1 or 6.1.2,  then such  adjustment  shall be made  pursuant to
Sections  6.1.1,  6.1.2,  6.1.3 and this Section  6.1.4.  The provisions of this
Section   6.1.4  shall   similarly   apply  to   successive   reclassifications,
reorganizations, mergers or consolidations, sales or other transfers.

     6.1.5 Changes in Form of Warrant.  This form of Warrant need not be changed
because of any change  pursuant to this Section,  and Warrants issued after such
change may state the same Exercise Price and the same number of shares of Common
Stock and Warrants as are stated in the Warrants  initially  issued  pursuant to
this  Agreement.  The  acceptance  by any Holder of the issuance of new Warrants
reflecting  a required  or  permissive  change  shall not be deemed to waive any
rights to a prior adjustment or the computation thereof.

     6.2 Elimination of Fractional Interests.  The Company shall not be required
to issue certificates  representing fractions of shares of Common Stock upon the
exercise of this Warrant, nor shall it be required to issue scrip or pay cash in
lieu of any  fractional  interests,  it being the intent of the parties that all
fractional  interests  shall be  eliminated  by rounding  any fraction up to the
nearest whole number of shares of Common Stock or other  securities,  properties
or rights.

     7. Reservation and Listing. The Company shall at all times reserve and keep
available out of its authorized  shares of Common Stock,  solely for the purpose
of issuance upon exercise of this Warrant, such number of shares of Common Stock
or other securities, properties or rights as shall be issuable upon the exercise
thereof.  The Company  covenants and agrees that,  upon exercise of the Warrants
and payment of the Exercise Price therefor, all shares of Common Stock and other
securities  issuable upon such exercise shall be duly and validly issued,  fully
paid and non-assessable and not subject to preemptive rights of any stockholder.
As long as the Warrants  shall be  outstanding,  the Company  shall use its best
efforts  to cause all  shares of Common  Stock  issuable  upon  exercise  of the
Warrants to be listed (subject to official notice of issuance) on all securities
exchanges (or, if applicable on Nasdaq) on which the Common Stock is then listed
and/or quoted.

8.    Certain Notice Requirements.

     8.1 Holder's Right to Receive Notice.  Nothing herein shall be construed as
conferring upon the Holders the right to vote or consent or to receive notice as
a stockholder  for the election of directors or any other  matter,  or as having
any rights whatsoever as a stockholder of the Company.  If, however, at any time
prior to the  expiration of the Warrants and their  exercise,  any of the events
described in Section 8.2 shall occur,  then, in one or more of said events,  the
Company  shall give written  notice of such event at least fifteen days prior to
the date fixed as a record  date or the date of closing the  transfer  books for
the determination of the stockholders  entitled to such dividend,  distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on such proposed dissolution, liquidation, winding up or sale. Such notice shall
specify  such record date or the date of the closing of the transfer  books,  as
the case may be.


                                                       5

<PAGE>



     8.2 Events  Requiring  Notice.  The  Company  shall be required to give the
notice described in this Section 8 upon one or more of the following events: (i)
if the Company  shall take a record of the holders of its shares of Common Stock
for the purpose of entitling them to receive a dividend or distribution  payable
otherwise  than in cash, or a cash dividend or  distribution  payable  otherwise
than out of retained earnings,  as indicated by the accounting treatment of such
dividend or distribution on the books of the Company,  or (ii) the Company shall
offer to all the holders of its Common  Stock any  additional  shares of capital
stock of the Company or securities  convertible  into or exchangeable for shares
of capital  stock of the Company,  or any option,  right or warrant to subscribe
therefor,  or (iii) a merger or  reorganization  in which the Company is not the
surviving party, or (iv) a dissolution, liquidation or winding up of the Company
(other than in connection  with a  consolidation  or merger) or a sale of all or
substantially all of its property, assets and business shall be proposed.

     8.3 Notice of Change in Exercise Price.  The Company shall,  promptly after
an event  requiring a change in the Exercise Price pursuant to Section 6 hereof,
send notice to the Holders of such event and change ("Price Notice").  The Price
Notice shall describe the event causing the change and the method of calculating
same and  shall  be  certified  as being  true  and  accurate  by the  Company's
President and Chief Financial Officer.

     8.4  Transmittal  of Notices.  All  notices,  requests,  consents and other
communications  under this  Warrant  shall be in writing  and shall be deemed to
have been duly made on the date of delivery if delivered  personally  or sent by
overnight courier,  with  acknowledgment of receipt by the party to which notice
is  given,  or on the fifth  day  after  mailing  if mailed to the party to whom
notice  is  to be  given,  by  registered  or  certified  mail,  return  receipt

registered Holder of this Warrant, to the address of such Holder as shown on the
books of the Company,  or (ii) if to the  Company,  to its  principal  executive
office.

9.       Miscellaneous.

     9.1  Headings.  The headings  contained  herein are for the sole purpose of
convenience  of reference,  and shall not in any way limit or affect the meaning
or interpretation of any of the terms or provisions of this Warrant.

     9.2 Entire Agreement.  This Warrant (together with the other agreements and
documents  being  delivered  pursuant  to or in  connection  with this  Warrant)
constitutes  the entire  agreement  of the parties  hereto  with  respect to the
subject matter hereof, and supersedes all prior agreements and understandings of
the parties, oral and written, with respect to the subject matter hereof.

     9.3 Binding  Effect.  This Warrant shall inure solely to the benefit of and
shall  be  binding  upon,  the  Holder  and the  Company  and  their  respective

respect of or by virtue of this Warrant or any provisions herein contained.

of the State of New York or of the  United  States of America  for the  Southern
District  of New York,  and  irrevocably  submits  to such  jurisdiction,  which

therefor.

     9.5  Waiver,  Etc.  The failure of the Company or the Holder to at any time
enforce any of the  provisions  of this Warrant shall not be deemed or construed
to be a waiver of any such provision, nor to in any way
                                                       6

instrument executed by the party or parties against whom or which enforcement of
such  waiver is  sought;  and no waiver of any such  breach,  non-compliance  or
non-fulfillment  shall be  construed  or  deemed  to be a waiver of any other or

                                                               EXHIBIT 4.6

                    WARRANT AND REGISTRATION RIGHTS AGREEMENT


     AGREEMENT,  dated as of the 27th day of  September,  1996,  by and  between
H.E.R.C.   PRODUCTS   INCORPORATED   ("Company")  and  THE  EQUITY  GROUP,  INC.
("Holder").

                  WHEREAS, on September 27, 1996 ("Date of Grant"),  the Company
agreed to issue a warrant  ("Warrant")  to The Equity  Group,  Inc.,  a New York
corporation  ("Equity"),  to purchase up to 50,000  shares of the common  stock,
$.01 par value ("Common Stock"),  and in connection therewith the Company agreed
to grant the registration  rights set forth below,  said Warrant being issued in
respect of Equity's services to the Company pursuant to that certain  Consulting
Agreement entered into between Equity and the Company on September 27, 1996 (the
"Consulting  Agreement")  pursuant to which Equity will render  financial public
relations and consulting services to the Company for a period of up to two years
until September 30, 1998.

                  NOW  THEREFORE,  in  consideration  of  the  covenants  herein
contained, the parties hereto hereby agree as follows:

     1. Issuance.  The Company hereby issues to the Holder the right to purchase
up to an aggregate of 50,000 shares of Common Stock on the terms and  conditions
herein set forth (such right being referred to as the "Warrant").

     2.  Purchaser  Price.  The  purchase  price of each  share of Common  Stock
subject to this Warrant shall be $2.75.

     3.  Exercise  and Term.  The Holder has the right to purchase the shares of
Common Stock subject to this Warrant from  September 27, 1996 until the close of
business on September 26, 2001.

     4. Payment of Exercise  Price.  The purchase price for the shares of Common
Stock  pursuant to which the Warrant is  exercised,  will be paid in full at the
time of exercise, in cash by certified check or wire transfer,  unless otherwise
agreed to in writing by the Company.  Exercise of any Warrant hereunder shall be
by written notice to the Company at its principal place of business,  specifying
the number of shares of Common Stock being  purchased and accompanied by payment
of the purchase price and any withholding tax obligations imposed on the Company
by reason of the exercise of the Warrant.  In the event that the tax obligation,
if any, is not paid,  the Company  will be  permitted to treat as payment of any
withholding  tax amount due,  the  exercise  of that  number of whole  shares of
Common Stock equal to the amount of the tax due divided by the fair market value
of the Common  Stock as of the date the  Warrant is  exercised,  and the Company
will be permitted to deduct such number of shares of Common Stock from the total
number being  exercised.  Certificates  representing  the shares as to which the
Warrant shall have been exercised  shall be registered in the name of the person
exercising the Warrant.

     5. Rights of Stockholder.  The Holder shall not have any of the rights of a
stockholder  with respect to the Common Stock  covered by the Warrant  until the
date of the issuance of a stock certificate for shares of Common Stock purchased
hereunder.

     6.  Transferability.  Unless consented to in writing by the Company,  which
consent  shall  not be  unreasonably  withheld,  this  Warrant  and  the  rights
conferred may not be transferred,  assigned,  pledged or hypothecated in any way
(whether  by  operation  of law or  otherwise)  and  shall  not  be  subject  to
execution,  attachment or similar process. Upon any attempt to transfer, assign,
pledge,  hypothecate or otherwise dispose of this Warrant or any right conferred
hereby,  or upon the levy of any  attachment  or  similar  process on the rights
conferred hereby,  without the written consent of the Company,  this Warrant and
the rights conferred hereby shall  immediately  become null and void. Before the
Company  consents to any transfer,  assignment,  pledge or hypothecation of
this Warrant, the transferee,  assignee or pledgee of the Warrant shall agree to
be bound by the terms of this  Warrant and deliver such other  certificates  and
agreements as the Company reasonably requests. Notwithstanding the foregoing and
subject to paragraph 8 below, the Warrant may be transferred to the then current
officers,   directors   and   shareholders   of  the  Holder   (the   "Permitted
Transferees"), provided such Permitted


<PAGE>



Transferees  agree to be bound by the terms of this  Warrant  and  deliver  such
certificates and agreements as the Company reasonably requests.

     7. Restricted  Nature of Securities.  This Warrant and the shares of Common
Stock  receivable  on the exercise of the Warrant are not  registered  under the
Securities  Act of 1933,  as amended (the "Act").  As a condition to the sale of
Common Stock on the exercise of the Warrant,  the person exercising such warrant
may be  required  by the  Company  to  give it such  documents,  including  such
appropriate  investment  representations  as may be  required by Counsel for the
Company  and such  additional  agreements  as the  Counsel  for the  Company may
determine,  as a  condition  to the  acceptance  of the  exercise of any Warrant
hereunder.

                  The  Holder  represents  that it has  received  and  carefully
reviewed the  Company's  Annual  Report on Form 10-KSB for the fiscal year ended
December 31, 1995, Quarterly Reports on Form 10-QSB for the quarters ended March
31, 1996 and June 30, 1996, and Annual Report to Stockholders  and related proxy
materials for the Company's Annual Meeting,  held on July 18, 1996, and has been
granted the opportunity to obtain any additional, publicly available information
relating to the Company and ask  questions of  executives of the Company that it
deems  necessary  to verify the  accuracy and  completeness  of the  information
provided to it.  Holder  represents  that it is acquiring  this Warrant and will
acquire the Common  Stock on its exercise  solely for its own  account,  for the
purpose of investment  and not with a view to or for resale in  connection  with
any  distribution  thereof,  except in compliance  with the Act, any  applicable
state  securities  laws  and  the  rules  and  regulations  thereunder.   Holder
represents  that its knowledge and experience in financial and business  matters
is such that it is capable of  evaluating  an investment in the Warrant and that
its financial condition is such that it can bear the economic risks of acquiring
and holding this Warrant.

     8. Sales Under  Securities Act.  Anything in this Agreement to the contrary
notwithstanding,  the Holder hereby  agrees that it shall not sell,  transfer by
any means or  otherwise  dispose of this  Warrant or the shares of Common  Stock
acquired  by him upon  exercise of the Warrant  hereunder  without  registration
under the Act,  or in the event that they are not so  registered,  unless (a) an
exemption from the Act is available thereunder, and (b) the Holder has furnished
the  Company  with  notice of such  proposed  transfer,  and the Counsel for the
Company, in its reasonable  opinion,  shall deem such proposed transfer to be so
exempt,  or the Holder has  furnished  the Company with notice of such  proposed
transfer,  together with an opinion of legal counsel reasonably  satisfactory to
the  Counsel for the  Company,  that in such  counsel's  opinion  such  proposed
transfer shall be so exempt.

     9.    Stop Transfer: Legend.

     (a) The Company may place stop  transfer  orders  with its  transfer  agent
against the  transfer of the shares of Common Stock  issuable  under the Warrant
hereof in the absence of  registration  under the Act or an exemption  therefrom
provided herein.

     (b) The  certificates  evidencing  shares  of Stock to be  issued  upon the
exercise of the Warrant may bear the following legends:

                           "The shares represented by this certificate have been
                           acquired for investment and have not been  registered
                           under the  Securities  Act of 1933,  as amended.  The
                           shares may not be sold or  transferred in the absence
                           of such registration or an exemption  therefrom under
                           said Act."

                           "The shares represented by this certificate have been
                           acquired  pursuant  to  an  warrant  agreement  dated
                           September  27,  1996, a copy of which is on file with
                           the Company,  and may not be transferred,  pledged or
                           disposed or exempt in  accordance  with the terms and
                           conditions thereof."

     10.            Adjustment to Number of Securities.

     (a) If the outstanding shares of Common Stock of the Company are increased,
decreased,  changed into or exchanged for a different number or kind of stock or
securities of the Company through stock  dividend,  stock split or reverse stock
split, or stock of a different par value or without par value through  amendment
to the Company's Certificate of Incorporation,  an appropriate and proportionate
adjustment  shall be made in the number and/or kind of  securities  allocated to
this Warrant,  without change in the aggregate  purchase price applicable to the
unexercised  portion  of the  outstanding  portion of this  Warrant,  but with a
corresponding  adjustment  in the price for each share of Common  Stock or other
unit of any security remaining covered by this Warrant.

     (b)  Upon the  effective  date of the  dissolution  or  liquidation  of the
Company, or of a reorganization, merger or consolidation of the Company with one
or more  corporations  in which the Company will not survive as an  independent,
publicly owned  corporation,  or of a transfer of substantially all the property
or more than eighty percent (80%) of the then outstanding shares of Common Stock
of the Company to another  corporation,  any  Warrant  granted  hereunder  shall
terminate   unless  provision  be  made  in  writing  in  connection  with  such
transaction for the assumption of the Warrant  granted,  or the substitution for
the Warrants of new warrants covering the shares of a successor corporation,  or
a parent or subsidiary  thereof,  with appropriate  adjustments as to number and
kind of stock and prices, in which event the Warrant  theretofore granted or the
new warrants substituted  therefor,  shall continue in the manner and under
the terms so provided.

     (c)  Adjustments  under  this  paragraph  shall  be  made by the  Board  of
Directors,  whose  determination as to what  adjustments  shall be made, and the
extent thereof, shall be final, binding and conclusive.  No fractional shares of
Stock shall be issued under any such adjustment.

     11.  "Piggyback" Registration.

     (a) Basic  Right.  If at any time prior to  September  26, 2001 the Company
proposes  to register  for sale by it or for the  account of others,  any of its
equity  securities  under  the Act,  other  than in  connection  with a  merger,
acquisition  or  exchange  offer,  and other than an offering on Form S-8 or any
successor form on which the Holder's securities may be registered,  and provided
further  that any person to which the Company has granted a  registration  right
prior to the Date of Grant does not object in  writing  to the  exercise  of the
Holder's  registration  rights  hereunder in  connection  with any  registration
rights of theirs,  the Company  shall,  at least  fifteen (15) days prior to the
filing  of  such  registration   statement  with  the  Securities  and  Exchange
Commission  (the  "Commission"),  give notice of its  intention  to do so to the
Holder. If the Holder notifies the Company within ten (10) days after the giving
of such  notice by the  Company of its  desire to  include  any shares of Common
Stock  received  on  exercise  of this  Warrant  in such  proposed  registration
statement  (which  notice must state the number of shares to be included and the
proposed  plan of  disposition  thereof),  the  Company  shall,  subject  to the
provisions  of  subparagraph  (b) below,  include the shares  designated by said
Holder  in such  registration  statement.  Notwithstanding  the  foregoing,  the
Company shall not be obligated to register any shares of Common Stock receivable
upon exercise of this Warrant at any time the shares are registered  pursuant to
an  effective  registration  statement  under the Act or the Holder may sell the
shares in a public transaction pursuant to Rule 144 promulgated under the Act or
pursuant to another exemption from registration of the shares and/or transaction
under the Act.

     (b) Withdrawal of Registration Statement. Notwithstanding the provisions of
subparagraph  (a) above,  the Company shall at all times have the absolute right
to elect not to file any  proposed  registration  statement,  or to withdraw the
same after the filing but prior to the  effective  date  thereof.  In  addition,
notwithstanding  the  provisions  of  subparagraph  (a) above,  the  Company may
exclude  from such  registration  statement  all or a portion  of the  shares of
Common  Stock for which  registration  was  requested  by the  Holder if, in the
written opinion of the Company's managing underwriter,  if any, the inclusion of
all or a portion of such shares,  when added to the securities  being registered
for sale by the  Company,  will  exceed  the  maximum  amount  of the  Company's
securities which can be marketed (i) at a price reasonably related to their then
current  market  value,  or (ii)  without  otherwise  materially  and  adversely
affecting the entire offering. If less than all of the shares



                                                       3

<PAGE>



of Common Stock requested for inclusion in said registration statement are to be
included pursuant to the foregoing  provision,  the shares of Common Stock which
are included shall be allocated among the selling  shareholders  (other than the
Company) on a pro rata basis.

     12. Terms and Conditions  Relating to Registration  of Shares.  Anything in
paragraph  11 above  contained to the contrary  notwithstanding,  the  following
terms and conditions shall apply to each  registration of shares of Common Stock
under the Act pursuant to the provisions of paragraph 11 above:

     (a)  Registration  Not  Required.  The  Company  shall not be  required  to
register any shares of Common Stock under the Act if, in the written  opinion of
counsel  for the  Company,  which  shall  be in form  and  substance  reasonably
satisfactory to the Holder of the relevant  shares of Common Stock,  said shares
may be sold in the  manner  set forth in the  notice to the  Company  requesting
registration without the need for compliance with the registration provisions of
the Act.

     (b)  Amendment  of   Registration   Statement.   The  Company   shall,   as
expeditiously as possible,  prepare and file with the Commission such amendments
and supplements to the  registration  statement (and to any prospectus  included
therein) as may be necessary to keep such registration statement effective until
the sale of the shares of Common Stock so registered has been completed or until
the  expiration  of a  period  of 90  days  after  the  effective  date  of  the
registration statement, whichever is earlier.

     (c)  Prospectuses,  etc. The Company shall  furnish to the selling  Holder,
such number of prospectuses, preliminary prospectuses and other documents as the
selling Holder may reasonably  request in order to facilitate the public sale of
its shares of Common Stock.

     (d)  Expenses.  The  Company  shall pay all  costs,  fees and  expenses  in
connection  with the  registration  of the  shares of Common  Stock,  including,
without limitation,  the Company's legal and accounting fees, printing expenses,
and blue sky fees and expenses; provided, however, that the Company shall not be
required to pay any (i) fees and expenses of legal counsel for the Holder,  (ii)
transfer  taxes,  or  (iii)   underwriters'  or  brokers'  fees,   discounts  or
commissions.

     (e) Indemnification.

     (1) By the  Company.  The  Company  shall  indemnify,  to the  full  extent
permitted by law, the Holder,  its  directors and officers (if  applicable)  and
each person, if any, who controls the Holder within the meaning of Section 15 of
the Act, against any losses, claims, damages, liabilities and expenses resulting
from any untrue or alleged untrue  statement of a material fact contained in any
registration statement,  prospectus or preliminary prospectus or any omission or
alleged  omission  to  state  therein  a  material  fact  necessary  to make the
statements therein (in the case of the prospectus or any preliminary prospectus,
in light of the circumstances under which they were made) not misleading, except
insofar as the same are caused by or contained in any  information  with respect
to the Holder  furnished in writing to the Company by the Holder  expressly  for
use therein.

     (2) By the Holder.  In connection with any registration  statement in which
the Holder is  participating,  the Holder  shall  indemnify,  to the full extent
permitted by law, the Company,  its  directors  and officers and each person who
controls  the Company  (within the meaning of Section 15 of the Act) against any
losses, claims,  damages,  liabilities and expenses resulting from any untrue or
alleged untrue  statement of a material fact or any omission or alleged omission
to state a material fact  necessary to make the  statements in the  registration
statement or prospectus or preliminary prospectus (in the case of the prospectus
or any preliminary  prospectus,  in light of the circumstances  under which they
were made) not  misleading,  to the extent,  but only to the  extent,  that such
untrue  statement or omission is contained in or caused by any information  with
respect  to the  Holder  furnished  in  writing  to the  Company  by the  Holder
expressly for use therein.




                                                       4

     (3)   Indemnification   Procedures.   Any   person  who  is   entitled   to
indemnification  under this  subparagraph  12(f) shall (i) give  prompt  written
notice to the  indemnifying  party of any claim  with  respect to which it seeks
indemnification and (ii) permit such indemnifying party to assume the defense of
such  claim with  counsel  reasonably  satisfactory  to the  indemnified  party.
Whether  or  not  such  defense  is  assumed  by  the  indemnifying  party,  the
indemnifying party shall not be subject to any liability for any settlement made
without  its  consent.  No  indemnifying  party  shall  consent  to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such  indemnified  party
of a release  from all  liability  in respect of such  claim or  litigation.  An
indemnifying  party who is not entitled to, or elects not to, assume the defense
of a claim will not be  obligated  to pay the fees and expenses of more than one
counsel for all parties  indemnified by such indemnifying  party with respect to
such  claim,  unless  in the  reasonable  judgment  of any  indemnified  party a
conflict of interest may exist between such  indemnified  party and any other of
such  indemnified  parties  with  respect  to such  claim,  in which  event  the
indemnifying  party  shall be  obligated  to pay the fees and  expenses  of such
additional counsel or counsels.


     (4) Contribution. If for any reason the indemnification provided for in the
preceding  subparagraph  12(f)(i) or  12(f)(ii)  is held by a court of competent
jurisdiction to be unavailable to an indemnified party with respect to any loss,
claim, damage,  liability or expense referred to therein,  then the indemnifying
party,  in  lieu  of  indemnifying  such  indemnified  party  thereunder,  shall
contribute to the amount paid or payable by the indemnified party as a result of
such loss,  claim,  damage or liability in such  proportion as is appropriate to
reflect not only the relative benefits received by the indemnified party and the
indemnifying party, but also the relative fault of the indemnified party and the
indemnifying party, as well as any other relevant equitable considerations.  The
relative fault of the indemnifying  party and of the indemnified  party shall be
determined by reference  to, among other  things,  whether the untrue or alleged
untrue  statement of a material fact or omission to state  material fact relates
to information  supplied by the indemnifying  party or by the indemnified  party
and  the  parties'  relative  intent,  knowledge,   access  to  information  and
opportunity to correct or prevent such statement or omission.

     (5) Actions by Holder. The Holder shall, at his cost and expense, complete,
execute and deliver all  questionnaires,  powers of attorney,  undertakings  and
other documents and  instruments,  and take all such other actions,  as are from
time to time reasonably requested by the Company.

     (6) Use of Prospectus.  The Holder, upon receipt of notice from the Company
of the occurrence of an event which requires a  post-effective  amendment to the
registration statement or a supplement to the prospectus included therein, shall
promptly  discontinue  the  sale of his  shares  of  Common  Stock  until he has
received copies of a supplemented or amended prospectus from the Company.

     13.   Miscellaneous Provisions.

     (a)  Applicable  Law. This  Agreement  will be deemed to have been made and
delivered in New York City and will be governed as to validity,  interpretation,
construction,  effect and in all other respects b the internal laws of the State
of New York.  The Company and the Holder each hereby agrees that any legal suit,
action or  proceeding  arising  out of or relating  to this  Agreement  shall be
instituted  exclusively in New York State Supreme Court,  County of New York, or
in the United  States  District  Court for the  Southern  District  of New York,
waives any objection to the venue of any such suit, action or proceeding and the
right to assert that such forum is not a convenient forum for such suit,  action
or proceeding,  irrevocably  consents to the  jurisdiction of the New York State
Supreme Court,  County of New York, and the United States District Court for the
Southern  District of New York in any such suit, action or proceeding and agrees
to accept and acknowledge  service or any and all process which may be served in
any such suit,  action or proceeding in New York State Supreme Court,  County of
New York or in the United States District Court for the Southern District of New
York and agrees that service of process upon it mailed by certified  mail to its
address  shall be deemed in every respect  effective  service of process upon in
any suit, action or proceeding.

H.E.R.C. Products Incorporated
2202 West Lone Cactus Drive, Suite 15
Phoenix, Arizona  85027

Dear Sirs:

   
         Reference   is  made  to  the   Registration   Statement  on  Form  S-3
("Registration  Statement") filed by H.E.R.C.  Products Incorporated ("Company")
under the  Securities  Act of 1933,  as  amended  ("Act"),  with  respect  to an
aggregate of 1,938,631 shares of common stock, par value $.01 per share ("Common
Stock")  to be  offered  and sold by those  persons  listed in the  Registration
Statement  as  Selling  Stockholders  ("Selling  Stockholders"),  including  (i)
1,603,631  shares of Common Stock to be issued by the Company upon conversion of
170,000  shares of Series A Preferred  Stock  ("Preferred  Stock") , (ii) 85,000
shares of  Common  Stock to be issued by the  Company  upon  exercise  of 85,000
Warrants issued to Perrin,  Holden & Davenport Capital Corp. ("PHD Warrants" and
"PHD,"  respectively),  (iii) 200,000 shares of Common Stock to be issued by the
Company upon exercise of 200,000  Warrants issued to GKN Securities  Corp. ("GKN
Warrants" and "GKN,"  respectively) and (iv) 50,000 shares of Common Stock to be
issued by the  Company  upon  exercise of 50,000  Warrants  issued to The Equity
Group, Inc.
    
("EGI Warrant" and "EGI," respectively).

         We have examined such documents and considered such legal matters as we
have deemed necessary and relevant as the basis for the opinion set forth below.
With  respect  to such  examination,  we have  assumed  the  genuineness  of all
signatures,  the authenticity of all documents submitted to us as originals, the
conformity to original documents of all documents  submitted to us as reproduced
or  certified  copies,  and the  authenticity  of the  originals of those latter
documents.  As to questions of fact  material to this  opinion,  we have, to the
extent  deemed  appropriate,  relied  upon  certain  representations  of certain
officers and employees of the Company.

   
         Based  upon the  foregoing,  it is our  opinion  that (i) the shares of
Common Stock being registered on the Registration Statement, to be issued by the
Company to certain of the Selling  Stockholders upon conversion of the Preferred
Stock  have been  duly  authorized  and,  when  issued  upon  conversion  of the
Preferred  Stock in accordance  with the terms thereof,  will be legally issued,
fully  paid and  non-assessable,  and (ii) the  shares  of  Common  Stock  being
registered on the Registration Statement, to be issued by the Company to certain
Selling  Stockholders  upon  exercise of the PHD  Warrants,  GKN Warrant and EGI
Warrant  have been duly  authorized  and,  when sold and paid for in the  manner
provided in the Registration  Statement and the warrant  agreements between PHD,
GKN and EGI and the Company,  respectively,  will be legally issued,  fully paid
and non-assessable.
    

         In giving this opinion,  we have assumed that, prior to their issuance,
all  certificates for the Company's shares of Common Stock will be duly executed
on behalf of the Company by the Company's  transfer  agent and registered by the
Company's registrar, if necessary, and will conform, except as to denominations,
to specimens which we have examined.

         We hereby  consent  to the use of this  opinion  as an  exhibit  to the
Registration  Statement,  to the use of our  name as  your  counsel,  and to all
references  made  to us in the  Registration  Statement  and  in the  Prospectus
forming a part thereof.  In giving this consent,  we do not hereby admit that we
are in the category of persons whose consent is required  under Section 7 of the
Act, or the rules and regulations promulgated thereunder.

                                                  Very truly yours,

                                                  /s/ Graubard Mollen & Miller

               CONSENT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS
