                               PROSPECTUS SUMMARY

THIS SUMMARY IS QUALIFIED BY THE MORE DETAILED  INFORMATION  APPEARING ELSEWHERE
IN THIS PROSPECTUS.


Our Business

      We develop, manufacture and market specialty chemicals that slow the
evaporation of water.

      Our HEAT$AVR(R) product is used in swimming pools and spas. This product
forms a thin, transparent layer on the water's surface. The transparent layer
slows the evaporation of water, allowing the water to retain a higher
temperature for a longer period of time and thereby reducing the energy required
to maintain the desired temperature of the water. Using the same technology, our
WATER$AVR(R) product, can also be used in reservoirs, potable water storage
tanks, livestock watering ponds, canals, and irrigation ditches where its use
slows water loss due to evaporation.

      We also manufacture and market TPA's, or biodegradable polymers, which are
used by the petroleum, chemical, utility and mining industries to prevent
corrosion and scaling in water piping. TPA's can also be used in detergents to
increase biodegradability and in agriculture to increase crop yields by
enhancing fertilizer uptake.

The Offering


      By means of this prospectus a number of our shareholders are offering to
sell up to 490,040 shares of our common stock which are issuable upon the
exercise of warrants. Warrants to purchase 443,240 shares were sold in a private
offering, together with shares of our common stock, in2007. Each warrant permits
the holder to purchase one share of our common stock at a price of $4.50 at any
time on or before May 30, 2010. Included in the shares offered by this
prospectus are 46,800 shares issuable upon the exercise of warrants issued to
sales agents participating in the private offering.

      As of September 30, 2009 we had 13,962,567 outstanding shares of common
stock. The number of outstanding shares does not give effect to shares which may
be issued upon the exercise of outstanding warrants or options. See "Comparative
Share Data".


      We will not receive any proceeds from the sale of the shares by the
selling shareholders.

      The purchase of the securities offered by this prospectus involves a high
degree of risk. Risk factors include our history of losses and the potential
need for additional capital. See the "Risk Factors" section of this prospectus
for additional risk factors.

Forward Looking Statements

      This prospectus contains various forward-looking statements that are based
on our belief as well as assumptions made by and information currently available
to us. When used in this prospectus, the words "believe", "expect",
"anticipate", "estimate" and similar expressions are intended to identify
forward-looking statements. Such statements may include statements regarding
future revenues, payment of operating expenses, and the like, and are subject to
certain risks, uncertainties and assumptions which could cause actual results to
differ materially from projections or estimates. Factors which could cause
actual results to differ materially are discussed at length under the heading
"Risk Factors". Should one or more of the enumerated risks or uncertainties
materialize, or should underlying assumptions prove incorrect, actual results
may vary materially from those anticipated, estimated or projected. Investors
should not place undue reliance on forward-looking statements, all of which
speak only as of the date made.

                                  RISK FACTORS

      The following is a discussion of important factors that could affect our
future operations and result in a decline in the market price of our common
stock.

We have  incurred  significant  operating  losses  since  inception  and may not
sustain profitability in the future.

We have experienced operating losses and negative cash flow from operations
since our inception and we currently have an accumulated deficit. To the extent
our revenues do not increase, our results of operations and liquidity will be
materially adversely affected. If we experience slower than anticipated revenue
growth or if our operating expenses exceed our expectations, we may not be
profitable. Even if we become profitable in the future, we may not remain
profitable.

Our failure to obtain capital may significantly restrict our operations.

We may need additional capital to fund our operating losses and to expand our
business. We do not know what the terms of any future capital raising may be but
any future sale of our equity securities would dilute the ownership of existing
stockholders and could be at prices substantially below the market price of the
shares of common stock sold in this offering. Our failure to obtain the capital
which we require may result in the slower implementation of our business plan or
our inability to implement our business plan. There can be no assurance that we
will be able to obtain any capital which we will need or how long we can remain
in operation.

We will not receive any proceeds from the sale of the shares offered by this
prospectus.

Shares  issuable  upon the  exercise of  outstanding  options and  warrants  may
substantially  increase  the number of shares  available  for sale in the public
market and may depress the price of our common stock.


We had outstanding options and warrants which, as of September 30, 2009, allowed
the holders to acquire a substantial number of shares of our common stock. Until
the options and warrants expire, the holders will have an opportunity to profit


                                       3


from any increase in the market price of our common stock without assuming the
risks of ownership. Holders of options and warrants may exercise these
securities at a time when we could obtain additional capital on terms more
favorable than those provided by the options or warrants. The exercise of the
options and warrants will dilute the voting interest of the owners of presently
outstanding shares by adding a substantial number of additional shares of our
common stock. See "Comparative Share Data" for additional information.


By means of this registration statement, as well as other registration
statements filed with the Securities and Exchange Commission, substantially all
of the shares of common stock which are issuable upon the exercise of the
outstanding options and warrants may be sold in the public market. The sale of
common stock issued or issuable upon the exercise of our outstanding options or
warrants, or the perception that such sales could occur, may adversely affect
the market price of our common stock.

Fluctuations in our operating results may cause our stock price to decline.

Given the nature of the markets in which we participate, we cannot reliably
predict future revenues and profitability. Changes in competitive, market and
economic conditions may cause us to adjust our operations. A high proportion of
our costs are fixed, due in part to our sales, research and development and
manufacturing costs. Thus, small declines in revenue could disproportionately
affect our operating results. Factors that may affect our operating results and
the market price of our common stock include:

     o    demand for and market acceptance of our products;

     o    competitive pressures resulting in lower selling prices;

     o    adverse changes in the level of economic  activity in regions in which
          we do business;

     o    adverse changes in industries, such as swimming pool construction,  on
          which we are particularly dependent;

     o    changes in the portions of our revenue represented by various products
          and customers;

     o    delays or problems in the introduction of new products;

     o    the  announcement  or  introduction  of  new  products,   services  or
          technological innovations by our competitors;

     o    variations in our product mix;

     o    the timing and amount of our  expenditures  in  anticipation of future
          sales;


                                       4


     o    increased costs of raw materials or supplies; and

     o    changes in the volume or timing of product orders.

Our operations are subject to seasonal fluctuation.

The use of our swimming pool products increases in summer months in most markets
and results in our sales from January to June being greater than in July through
December. Markets for our WATER$AVR(R) product are also seasonal, dependent on
the wet versus dry seasons in particular countries. We attempt to sell into a
variety of countries with different seasons on both sides of the equator in
order to minimize seasonality. Our TPA business is the least seasonal, however
there is a small increase in the spring related to inventory building for the
crop season in the United States and a small slowdown in December as oilfield
customers run down stock in advance of year end, but otherwise, little seasonal
variation. We believe we are able to adequately respond to these seasonal
fluctuations by reducing or increasing production as needed.

Interruptions  in our ability to  purchase  raw  materials  and  components  may
adversely affect our profitability.

We purchase certain raw materials and components from third parties pursuant to
purchase orders placed from time to time. Because we do not have guaranteed
long-term supply arrangements with our suppliers, any material interruption in
our ability to purchase necessary raw materials or components could have a
material adverse effect on our business, financial condition and results of
operations.

Our WATER$AVR(R) product has not proven to be a revenue producing product and we
may never recoup the cost associated with its development.

The marketing efforts of our WATER$AVR(R) product may result in continued
losses. We introduced our WATER$AVR(R) product in June 2002 and, to date, we
have delivered quantities for testing by potential customers, but only a few
customers have ordered the product for commercial use. This product can achieve
success only if it is ordered in substantial quantities by commercial customers
who have determined that the water saving benefits of the product exceed the
costs of purchase and deployment of the product. We can offer no assurance that
we will receive sufficient orders of this product to achieve profits or cover
the additional expenses incurred to manufacture and market this product.

If we do not  introduce  new products in a timely  manner,  our  products  could
become obsolete and our operating results would suffer.

Without the timely introduction of new products and enhancements, our products
could become obsolete over time, in which case our revenue and operating results
would suffer. The success of our new product offerings will depend upon several
factors, including our ability to:

     o    accurately anticipate customer needs;


                                       5


     o    innovate and develop new products and applications;

     o    successfully commercialize new products in a timely manner;

     o    price our  products  competitively  and  manufacture  and  deliver our
          products in sufficient volumes and on time; and

     o    differentiate our products from our competitors' products.

In developing any new product, we may be required to make a substantial
investment before we can determine the commercial viability of the new product.
If we fail to accurately foresee our customers' needs and future activities, we
may invest heavily in research and development of products that do not lead to
significant revenues.

We are dependent upon certain customers.

Among our current customers, we have identified six that are sizable enough that
the loss of any one would be significant. Any such loss of one or more of these
customers could result in a substantial reduction in our revenues. For this
reason, we concentrate on maintaining good sales relations with these customers.
We also try and minimize this risk by seeking out new customers.

Economic,  political and other risks  associated  with  international  sales and
operations could adversely affect our sales.

Shipments made outside of the United States accounted for approximately 79% of
our revenues during the year ended December 31, 2008 and approximately 79% of
our revenues during the year ended December 31, 2007. Since we sell our products
worldwide, our business is subject to risks associated with doing business
internationally. We anticipate that revenues from international operations will
continue to represent a sizable portion of our total revenue. Accordingly, our
future results could be harmed by a variety of factors, including:

     o    changes in foreign currency exchange rates;

     o    changes in a country or region's  political  or  economic  conditions,
          particularly in developing or emerging markets;

     o    longer  payment   cycles  of  foreign   customers  and  difficulty  of
          collecting receivables in foreign jurisdictions;

     o    trade protection measures and import or export licensing requirements;

     o    differing tax laws and changes in those laws;

     o    difficulty in staffing and managing widespread operations;


                                       6


     o    differing  protection  of  intellectual  property  and changes in that
          protection; and

     o    differing regulatory requirements and changes in those requirements.

We are subject to credit risk and may be subject to  substantial  write-offs  if
one or more of our significant customers default on their payment obligations to
us.

We currently allow our major customers between 30 and 45 days to pay for each
shipment of product we make to them. This practice, while customary, presents an
accounts receivable write-off risk in that if one or more of our significant
customers defaulted on their payment obligations to us, such write-off, if
substantial, would have a material adverse effect on our business and results of
operations. While we have exposure to this type of risk, we are no longer
subject to the concentrated credit risk that we were previously subject to
because of our relationship with Sun Solar. In addition, while our exposure to a
bad debts and write-offs credit risk may increase as we service a larger number
of customers in the swimming pool and personal spa, water evaporation and TPA
industries, the effect of any such bad debts and write-offs will be minimized as
a result of the increase in the numbers of our customers and overall revenues.

Our  products  can be  hazardous  if not  handled,  stored  and  used  properly;
litigation  related to the  handling,  storage and safety of our products  would
have a material adverse effect on our business and results of operations.

Some of our products are flammable and must be stored properly to avoid fire
risk. Additionally, some of our products may cause irritation to a person's eyes
if they are exposed to the concentrated product. Although we label our products
to warn of such risks, our sales could be reduced if our products were to be
viewed as being dangerous to use or if they are implicated in causing personal
injury or property damage. We are not currently aware of any circumstances in
which our products have caused harm or property damage to consumers.
Nevertheless, litigation regarding the handling, storage and safety of our
products would have a material adverse effect on our business and results of
operations.

Our  failure to comply with  environmental  regulations  may create  significant
environmental liabilities and force us to modify our manufacturing processes.

We are subject to various federal, state and local environmental laws,
ordinances and regulations relating to the use, storage, handling and disposal
of certain of our chemical substances. Under such laws, we may become liable for
the costs of removal or remediation of these substances that have been used by
our consumers or in our operations. Such laws may impose liability without
regard to whether we knew of, or caused, the release of such substances. Any
failure by us to comply with present or future regulations could subject us to
the imposition of substantial fines, suspension of production, alteration of
manufacturing processes or cessation of operations, any of which could have a
material adverse effect on our business, financial condition and results of
operations.



                                       7



Our failure to protect our  intellectual  property could impair our  competitive
position.

While we own certain patents and trademarks, some aspects of our business cannot
be protected by patents or trademarks. Accordingly, in these areas there are few
legal barriers that prevent potential competitors from copying certain of our
products, processes and technologies or from otherwise entering into operations
in direct competition with us. In particular, we have been informed that our
former exclusive agent for the sale of our products, Sun Solar, is now competing
with us in the swimming pool and personal spa markets. As a former distributor,
they were given access to many of our sales, marketing and manufacturing
techniques. Accordingly, we are doing all that we can to ensure our proprietary
products and technologies are not used by them (or others) without our
permission.

Our products may infringe on the  intellectual  property  rights of others,  and
resulting  claims  against  us could be costly  and  prevent  us from  making or
selling certain products.

Third parties may seek to claim that our products and operations infringe their
patent or other intellectual property rights. We may incur significant expense
in any legal proceedings to protect our proprietary rights or to defend
infringement claims by third parties. In addition, claims of third parties
against us could result in awards of substantial damages or court orders that
could effectively prevent us from making, using or selling our products in the
United States or abroad.

A claim  for  damages  could  materially  and  adversely  affect  our  financial
condition and results of operations.

Our business exposes us to potential product liability risks, particularly with
respect to our consumer swimming pool and consumer TPA products. There are many
factors beyond our control that could lead to liability claims, including the
failure of our products to work properly and the chance that consumers will use
our products incorrectly or for purposes for which they were not intended. There
can be no assurance that the amount of product liability insurance that we carry
will be sufficient to protect us from product liability claims. A product
liability claim in excess of the amount of insurance we carry could have a
material adverse effect on our business, financial condition and results of
operations.

Our ongoing success is dependent upon the continued  availability of certain key
employees.

Our business would be adversely affected if the executive services of Daniel B.
O'Brien ceased to be available to us because we currently do not have any other
employee with an equivalent level of expertise in and knowledge of our industry.
If Mr. O'Brien no longer served as our President and Chief Executive Officer, we
would have to recruit one or more new executives, with no real assurance that we
would be able to engage a replacement executive with the required skills on
satisfactory terms. The market for skilled employees is highly competitive,
especially for employees in the fields in which we operate. While our
compensation programs are intended to attract and retain the employees required
for it to be successful, there can be no assurance that we will be able to
retain the services of all our key employees or a sufficient number to execute


                                       8


on our plans, nor can there be any assurances that we will be able to continue
to attract new employees as required.

      None of the selling shareholders had or ever had, any material
relationship with us or our officers or directors. To our knowledge, none of the
selling shareholders are affiliated with a broker dealer except for FIG
Partners, LLC and Barretto Securities.

      All of the selling shareholders acquired the shares they are offering by
means of this prospectus in the ordinary course of business. At the time they
acquired these shares the selling shareholders did not have any agreements or
understandings, directly or indirectly, with any person to distribute their
shares.

Manner of Sale
--------------

      The shares of common stock to be sold by the selling shareholders may be
offered and sold by means of this prospectus from time to time as market
conditions permit. These shares may be sold by one or more of the following
methods, without limitation:

     o    a block trade in which a broker or dealer so engaged  will  attempt to
          sell the shares as agent but may  position and resell a portion of the
          block as principal to facilitate the transaction;

     o    purchases by a broker or dealer as principal and resale by such broker
          or dealer for its account pursuant to this prospectus;

     o    ordinary  brokerage  transactions and transactions in which the broker
          solicits purchasers; and

     o    face-to-face  transactions  between  sellers and purchasers  without a
          broker/dealer.

      In competing sales, brokers or dealers engaged by the selling shareholders
may arrange for other brokers or dealers to participate. Brokers or dealers may
receive commissions or discounts from the selling shareholders in amounts to be
negotiated. As to any particular broker-dealer, this compensation might be in
excess of customary commissions. We cannot and the selling shareholders cannot
presently estimate the amount of such compensation. Notwithstanding the above,
no NASD member will charge commissions that exceed 8% of the total proceeds from
the sale.


                                       12


      The selling shareholders and any broker/dealers who act in connection with
the sale of the shares may be deemed to be "underwriters" within the meaning of
ss.2(11) of the Securities Acts of 1933, and any commissions received by them
and any profit on any resale of the shares as principal might be deemed to be
underwriting discounts and commissions under the Securities Act.

    If any selling shareholder enters into an agreement to sell its shares to a
broker-dealer as principal, and the broker-dealer is acting as an underwriter,
we will file a post-effective amendment to the registration statement, of which
this prospectus is a part, identifying the broker-dealer, providing required
information concerning the plan of distribution, and otherwise revising the
disclosures in this prospectus as needed. We will also file the agreement
between the selling shareholder and the broker-dealer as an exhibit to the
post-effective amendment to the registration statement.

      The selling shareholders may also sell their shares pursuant to Rule 144
under the Securities Act of 1933.

    We have has advised the selling shareholders that they, and any securities
broker/dealers or others who may be deemed to be statutory underwriters, will be
subject to the prospectus delivery requirements under the Securities Act of
1933. We have has also advised the selling shareholders that in the event of a
"distribution" of the shares owned by the selling shareholders, the selling
shareholders, any "affiliated purchasers", and any broker/dealer or other person
who participate in the distribution may be subject to Rule 102 of Regulation M
under the Securities Exchange Act of 1934 ("1934 Act") until their participation
in the distribution is completed. Rule 102 makes it unlawful for any person who
is participating in a distribution to bid for or purchase stock of the same
class as is the subject of the distribution. A "distribution" is defined in Rule
102 as an offering of securities "that is distinguished from ordinary trading
transactions by the magnitude of the offering and the presence of special
selling efforts and selling methods". We have has also advised the selling
shareholders that Rule 101 of Regulation M under the 1934 Act prohibits any
"stabilizing bid" or "stabilizing purchase" for the purpose of pegging, fixing
or stabilizing the price of the common stock in connection with this offering.

                            DESCRIPTION OF SECURITIES

Common Stock

      We are authorized to issue 50,000,000 shares of common stock. Holders of
common stock are each entitled to cast one vote for each share held of record on
all matters presented to shareholders. Cumulative voting is not allowed; hence,
the holders of a majority of the outstanding common stock can elect all
directors.

      Holders of common stock are entitled to receive dividends as may be
declared by our Board of Directors out of funds legally available and, in the
event of liquidation, to share pro rata in any distribution of our assets after
payment of liabilities. Our directors are not obligated to declare a dividend.
It is not anticipated that dividends will be paid in the foreseeable future.


                                       13


      Holders of our common stock do not have preemptive rights to subscribe to
additional shares if issued. There are no conversion, redemption, sinking fund
or similar provisions regarding our common stock. All our outstanding shares are
fully paid and non-assessable.

Preferred Stock

      We are authorized to issue 1,000,000 shares of preferred stock. Our
Articles of Incorporation provide that our Board of Directors has the authority
to divide the preferred stock into series and, within the limitations provided
by Nevada law, to fix by resolution the voting power, designations, preferences,
and relative participation, special rights, and the qualifications, limitations
or restrictions of the shares of any series established. As our Board of
Directors has authority to establish the terms of, and to issue, the preferred
stock without shareholder approval, the preferred stock could be issued to
defend against any attempted takeover.

Options and Warrants


      See the "Comparative Share Data" section of this prospectus for
information concerning our outstanding options and warrants.


Transfer Agent

     Computershare  Trust Company,  Inc., of Golden,  Colorado,  is the transfer
agent for our common stock.

                                  LEGAL MATTERS

     The validity of the securities  offered by this  prospectus has been passed
upon by Hart & Trinen, Denver, Colorado.

                                 INDEMNIFICATION

     The  Nevada  Revised  Statutes  authorize  indemnification  of  any  of our
directors or officers against  expenses  incurred in connection with any action,
suit,  or proceeding to which the director or officer is named a party by reason
of his or her having acted or served in such  capacity,  except for  liabilities
arising from his or her own misconduct or negligence. In addition, a director or
officer  who was found  liable for  misconduct  or  negligence  may obtain  such
indemnification  if, in view of all the  circumstances  in the case,  a court of
competent jurisdiction  determines such person is fairly and reasonably entitled
to indemnification. Insofar as indemnification for liabilities arising under the
Securities  Act of 1933 may be permitted to our directors or officers,  pursuant
to the  foregoing  provisions,  we have been informed 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.


                                       14

Item 17. Undertakings.
         ------------

      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 l0(a)(3) of the
Securities Act of l933;

            (ii) To reflect in the prospectus any facts or events arising after
the effective date of the Registration Statement (or the most recent
post-effective amendment thereof) which, individually or in the aggregate,
represent a fundamental change in the information set forth in 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, including
(but not limited to) any addition or deletion of a managing underwriter.

      (2) That, for the purpose of determining any liability under the
Securities Act of l933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

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

      (4) 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 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.

      (5) That, for the purpose of determining liability under the Securities
Act of 1933 to any purchaser:

      (i) If the registrant is relying on Rule 430B:

            (A) Each prospectus filed by the registrant pursuant to Rule
424(b)(3) shall be deemed to be part of the registration statement as of the
date the filed prospectus was deemed part of and included in the registration
statement; and


                                       2



            (B) Each prospectus required to be filed pursuant to Rule 424(b)(2),
(b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B
relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for
the purpose of providing the information required by section 10(a) of the
Securities Act of 1933 shall be deemed to be part of and included in the
registration statement as of the earlier of the date such form of prospectus is
first used after effectiveness or the date of the first contract of sale of
securities in the offering described in the prospectus. As provided in Rule
430B, for liability purposes of the issuer and any person that is at that date
an underwriter, such date shall be deemed to be a new effective date of the
registration statement relating to the securities in the registration statement
to which that prospectus relates, and the offering of such securities at that
time shall be deemed to be the initial bona fide offering thereof. Provided,
however, that no statement made in a registration statement or prospectus that
is part of the registration statement or made in a document incorporated or
deemed incorporated by reference into the registration statement or prospectus
that is part of the registration statement will, as to a purchaser with a time
of contract of sale prior to such effective date, supersede or modify any
statement that was made in the registration statement or prospectus that was
part of the registration statement or made in any such document immediately
prior to such effective date; or

    (ii) If the registrant is subject to Rule 430C, each prospectus filed
pursuant to Rule 424(b) as part of a registration statement relating to an
offering, other than registration statements relying on Rule 430B or other than
prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and
included in the registration statement as of the date it is first used after
effectiveness. Provided, however, that no statement made in a registration
statement or prospectus that is part of the registration statement or made in a
document incorporated or deemed incorporated by reference into the registration
statement or prospectus that is part of the registration statement will, as to a
purchaser with a time of contract of sale prior to such first use, supersede or
modify any statement that was made in the registration statement or prospectus
that was part of the registration statement or made in any such document
immediately prior to such date of first use.

      Insofar as indemnification for liabilities arising under the Securities
Act of l933 may be permitted to directors, officers and controlling persons of
the Registrant, 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 of 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.

                                POWER OF ATTORNEY

                                   SIGNATURES

     Pursuant to the  requirements of the Securities Act of l933, the Registrant
certifies  that it has  reasonable  grounds  to  believe  that it meets  all the

Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly
