                                     PART I

ITEM 1. DESCRIPTION OF  BUSINESS.

        General. Sionix Corporation, formerly Coronado Capital Corporation
(the"Company") designs and manufactures equipment for improving the treatment of
water for commercial, industrial and public water treatment facilities. To date
the Company's principal activities have been in the areas of research,
development and testing of its products. The Company's executive offices and
principal operations are located at 9272 Jeronimo Road, Irvine, California
92618, its telephone number is (949) 454-9283, and its website is located at
www.sionix.com.

        Strategy. The Company was formed to develop advanced water treatment
technology for public and private potable drinking water systems and wastewater
treatment systems, as well as industrial systems. It is estimated that in the
United States alone, there are approximately 197,060 public rural water
districts, the great majority of which are considered small public water
systems, with populations less then 10,000. Reports of the U.S. Environmental
Protection Agency in the Federal Registry listed over 50,000 communities in the
United States that are currently in violation of the Safe Drinking Water Act,
and those numbers are expected to increase as more stringent EPA rules for small
public water systems become effective. In addition, urbanization in the third
world and the spread of agricultural activities have increased the demand for
public water systems. The company has targeted (1) small public water districts,
with limited financial resources, which provide communities with drinking water
or sewage treatment service and (2) water reclamation systems of
commercial-industrial clients that create and dispose of contaminated
wastewater.

        Products

        Sionix Modular Solids Separator Filtration System. Dissolved Air
Flotation ("DAF") technology is an established method for water treatment. The
Company's DAF Particle Separator utilizes and refines this technology for a
highly efficient pre-treatment process using ordinary oxygen. In addition, it
helps ordinary filters meet new EPA Safe Drinking Water Act (SDWA) regulations
and eliminates potentially cancer-causing disinfection by-product precursors
while reducing the risk of bacterial or parasitic contamination, particularly
THM's, cryptosporidium and giardia. The Company's patented equipment systems are
designed for quick installation, easy access for simple maintenance and to be
cost-effective for even the smallest water utilities or commercial applications.

        A major problem facing the water treatment industry is the difficulty in
monitoring and disposing of microscopic parasites such as Cryptosporidium (4-5
microns) and Giardia cysts (7-12 microns), common chlorine-resistant organisms
that have infected millions of people in the United States. Sand-anthracite
water filtration beds, in use in most of the nation's public water districts,
will not filter out these parasites and experience frequent breakthroughs of
Cryptosporidium sized particles.

        The Company uses a more efficient method of saturating recirculated
post-filter water with excess dissolved air, and applying this excess air in the
form of microscopic bubbles in a particle separator. Pressurized water


                                       2
<PAGE>   3

can hold an excess amount of dissolved air and forms microscopic bubbles when
injected into water which has a lower pressure. A booster pump recirculates a
small amount (10%) of the post-filtered water through the dissolved
air-saturation assembly. A compressor forces air under high pressure through
small hollow-fiber polyolefin membrane fibers inside the air saturation assembly
housing. Oxygen and nitrogen molecules are transferred directly into the
recirculated high pressure water without forming air bubbles. This method of
transferring air into water is 100% efficient, and reduces the amount of energy
required to saturate recirculated water with excess dissolved air. The Sionix
DAF separator provides a denser concentration of white water bubbles. This
process requires less energy than a conventional system, and a fraction of the
floor space.

        In general, water districts using sand-anthracite filters cannot meet
the new EPA Surface Water Treatment rules without a massive increase in on-site
chemical filter-aids and the installation of ozone equipment. Plant operators
must continually test raw influent water to adjust chemical filter aid dosage
properly. Chemical and metal (alum) filter-aids increase sludge volume and
landfill disposal problems.

        Each basic DAF module has a flow-through of 200 gallons per minute
(288,000 gallons per day), an amount necessary to supply all the drinking and
potable water requirements for approximately 2,400 people. And because modules
can be manifolded to meet any gallon per day requirement, many larger facilities
can benefit by this technology.

        The Company's systems include automatic computer controls to optimize
ozone concentration levels and reduce monthly energy costs. Higher ozone contact
concentration levels using smaller sized generators are possible if most of the
algae is first removed by DAF. Extended contact time increases collision rate of
ionized ozone molecules with negatively charged organic suspended particles. By
utilizing the Sionix DAF particle separator to pre-treat the feedwater, less
energy is required to create the appropriate amount of ozone. By creating a
turbulent flow of water and gas within the mixing chamber, the Company has
achieved a much higher saturation with less ozone (and a minimum of excess
ozone) than in other mixing methods. This equipment was designed to match
flow-throughs with the Sionix DAF particle separator, can also be manifolded to
create more flow-through, is installed, not constructed, and can be used with or
without the DAF system, depending on the quality of the feedwater.

       Marketing and Customers. In the United States, the Company plans to
initially target the established base of 185,000 small to very small water
providers, as well as industrial users (such as the dairy industry, meat and
poultry producers, food and beverage processors, cooling tower manufacturers and
oil and gas producers) with a need for a clean, consistent water supply. In
addition to the domestic markets, the Company has been contacted by
representatives from local water systems in Europe, Latin America and Asia.

        The Company's marketing efforts emphasize that its products are easily
expandable and upgradable; for example, adding ozone and microfiltration
equipment to a DAF unit is similar to adding a new hard drive to a personal
computer. Each piece of equipment comes with state-of-the-art telemetry and
wet-chemistry monitoring that expands as the system does. The Company plans to
provide lease financing for all of its products, not only making it easy for a
customer to acquire the equipment, but also guaranteeing


                                       3
<PAGE>   4

that the customer will always have access to any refinements and improvements
made to the Company's products.

        The Company plans to market its products through direct mail,
participation in industry groups and trade shows, and through selected
advertising in specialized publications.

        Patents. The Company holds three U.S. patents on technology incorporated
into the Sionix Particle Separator Treatment System. One of the patents
generally relates to the vortex system in the DAF Particle Separator, and
another concerns the ozone mixing system. The third patent covers an automatic
backflushing system using air pressure to activate the valves. The Company also
holds several patents on the inline wet-chemistry water quality monitoring
system. In addition, several active patent applications are being processed. The
extent to which patents provide a commercial advantage or inhibit the
development of competing products varies. To some extent, however, the Company
is required to rely upon common law concepts of confidentiality and trade
secrets, as well as economic barriers created by the required investments in
tooling and technical personnel and the development of customer relationships,
to protect its proprietary products.

        Employees. At November 30, 1999, the Company had four full-time
employees, none of whom are covered by any collective bargaining agreement. The
Company considers its relationship with its employees to be good.

        Research and Development. The Company invests significantly in the
development of products for new applications. Only direct costs associated with
tooling for new products are capitalized. All other costs, including salaries
and wages of employees included in research and development, are expensed as
incurred. Most of the Company's research and development efforts are in
connection with development and refinement of the DAF Particle Separator and
related components.

        Raw Materials. Materials and components used by the Company for
manufacturing are carefully selected based on stringent specifications for usage
and operating conditions. Every effort is made to specify parts from multiple
sources for independence from manufacturers and distributors. The Company has
avoided using hard-to-get special parts to further minimize dependency from
vendors. Simplicity in design and the use of common, widely used and readily
available components is emphasized.

ITEM 2.  DESCRIPTION OF PROPERTY.

        The Company's office/manufacturing facility is located in Irvine,
California and is leased pursuant to a lease expiring in July of 2001. The
facility consists of approximately 3,400 square feet, including office area and
adjoining manufacturing/warehouse area. Management believes the Company's
facility will provide adequate space for its office, product assembly and
warehouse activities, although it may lease additional space for component
assembly and warehouse uses, depending on demand. The Company believes that
suitable additional space will be available to accommodate planned expansion.

ITEM 3. LEGAL PROCEEDINGS.

         In June 1999 the Company filed an action against Jack Moorehead,
Dascore, LLC, S. Donna Friedman and certain others in the U.S. District Court
for the Southern District of California (Case No. 99-cv-1201-K-LSP).


                                       4
<PAGE>   5

Moorehead is the former President of the Company, and Dascore LLC is an entity
controlled by him and in a business related to that of the Company. S. Donna
Friedman is a former officer and director of the Company.

         The Complaint alleges, among other things, that the defendants have
infringed and continue to infringe on certain patents owned by the Company, and
that they are familiar with the Company's intellectual property through their
past positions with the Company. The Complaint also alleges that the defendants
have sold or attempted to sell technology owned by the Company and covered by
the Company's patents, and that the defendants are unfairly competing with the
Company by exploiting its technology without payment. In addition, the action
includes claims of false advertising, in that the defendants are falsely
representing that they own the technology; interference with economic relations
and interference with prospective advantage, relating to the effect that the
defendants' conduct has had on the Company's dealings with third parties; and
misappropriation of trade secrets learned by the defendants while associated
with the Company. The complaint further alleges that the defendants conspired to
convert technology, money and equipment owned by the Company, and used Company
funds to pay personal expenses. Finally, the complaint alleges that Moorehead
and Friedman defrauded the Company and breached their fiduciary duties to the
Company in connection with their departure from the Company and their retention
of property of the Company.

         In the Complaint, the Company seeks monetary damages in an amount to be
determined, injunctive relief, an accounting and a declaratory judgment. The
case is currently in the discovery stage.

ITEM 5.  MARKET FOR COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

        The Company's Common Stock is listed and traded on the OTC Bulletin
Board under the symbol "SINX". There has been relatively limited trading
activity in the Company's stock since inception. The following table represents
the high and low bid prices for the Company's common stock for each quarter of
the fiscal year ended September 30, 1999.

            Fiscal 1999              High            Low

        There were approximately 625 holders of record of the Company's common
stock as of September 30, 1999.

        The Company has never declared or paid any cash dividend on its shares
of common stock.

        During the fiscal year ended September 30, 1999, the Company sold
9,383,000 shares of Common Stock to approximately 73 purchasers, with gross
proceeds of $938,300. The Company believes all such sales were exempt from
registration under the Securities Act of 1933 by reason of Section 4(2) thereof
and Regulation D thereunder.


ITEM 6. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

        General.

        As of September 30, 1999, the Company had an accumulated deficit of
$5,361,639. It can be expected that the future operating results will continue
to be subject to many of the problems, expenses, delays and risks inherent in
the establishment of a new business enterprise, many of which the Company cannot
control.

        The Company has formulated its business plans and strategies based on
certain assumptions of the Company's management regarding the size of the market
for the products which the Company will be able to offer, the Company's
anticipated share of the market, and the estimated prices for and acceptance of
the Company's products. The Company continues to believe its business plans and
the assumptions upon which they are based are valid. Although these plans and
assumptions are based on the best estimates of management, there can be no
assurance that these assessments will prove to be correct. No independent
marketing studies have been conducted on behalf of or otherwise obtained by the
Company, nor are any such studies planned. Any future success that the Company
might enjoy will depend upon many factors, including factors which may be beyond
the control of the Company or which cannot be predicted at this time. These
factors may include product obsolescence, increased levels of competition,
including the entry of additional competitors and increased success by existing
competitors, changes in general economic conditions, increases in operating
costs including cost of supplies, personnel and equipment, reduced margins
caused by competitive pressures and other factors, and changes in governmental
regulation imposed under federal, state or local laws.

        The Company's operating results may vary significantly due to a variety
of factors, including changing customers profiles, the availability and cost of
raw materials, the introduction of new products by the Company or its
competitors, the timing of the Company's advertising and promotional campaigns,
pricing pressures, general economic and industry conditions that affect customer
demand, and other factors.

        Results of Operations (Year Ended September 30, 1999 Compared to Year
Ended September 30, 1998). During the 1999 fiscal year the focus of the
Company's efforts has been on development, manufacturing and distribution of the
Company's hardware products. The immediate focus is on the DAF (Dissolved Air
Flotation), Automatic Back-Flush Filtration System, O-Zone Mixing Chamber and
other related products, some of which have their own separate markets.


                                       6
<PAGE>   7

         The Company is continuing its engineering focus on hardware and water
filtration equipment. The first phase of testing was completed in November 1998.
The second phase of testing was completed in April 1999 and has revealed useful
data. Final testing is expected to begin in January 2000 for the first
production unit. Management is implementing engineering changes prior to the
execution of contracts for production tooling. Management is in negotiations
with suppliers for tooling and production of various support products that have
their own markets. The Company expects that it will implement minor engineering
adjustments in tooling prior to the execution of contracts for production
tooling.

        For the year ended September 30, 1999, the Company reported a loss of
$765,830, or $.02 per share. This compares with a loss of $1,898,376 or $.08 for
the year ending September 30, 1998. The reduction in the loss is principally due
to a write-down of certain intangible assets in the 1998 fiscal year, decreased
interest expense, and decreases in general and administrative expenses.

        Liquidity and Capital Resources. On September 30, 1999, the Company had
cash and cash equivalents of approximately $184,461. The principal source of
liquidity has been sales of securities. Management anticipates that additional
capital will be required to finance the Company's operations. The Company
believes that expected cash flow from operations plus the anticipated proceeds
from sales of securities will be sufficient to finance the Company's operations
at currently anticipated levels for a period of at least twelve months. However,
there can be no assurance that the Company will not encounter unforeseen
difficulties that may deplete its capital resources more rapidly than
anticipated.

Year 2000 Issues

        The "year 2000" issue concerns the potential exposure related to the
possible automatic generation of business and financial misinformation resulting
from the application of computer programs which have been written using two
digits, rather than four, to define the applicable year of business
transactions.

        The Company is dependent on multiple computer servers and the
third-party computer programs running on them to provide data in support of its
accounting and engineering functions. The Company's preparation for year 2000
compliance included the following phases: (i)it conducted a comprehensive
inventory of the Company's internal systems, including information technology
systems and non-information technology systems and the systems acquired or to be
acquired by the Company from third parties, (ii) it assessed and prioritized any
required changes, upgrades, or enhancements, (iii) it resolved any problems by
repairing or, if appropriate, replacing the non-compliant systems, (iv) it
tested any remediated systems for Year 2000 compliance, and (v) it developed
contingency plans to be employed in the event that any system used by the
Company was unexpectedly affected by a previously unanticipated problem relating
to the Year 2000.

       To date the Company has not experienced any significant problems as a
result of the change in the year. It will continue to monitor its systems to
determine whether any problems arise.

                          INDEPENDENT AUDITORS' REPORT
                          ----------------------------


To the Board of Directors and Stockholders
Sionix Corporation
(A Development Stage Company)
Irvine, California

We have audited the accompanying balance sheet of Sionix Corporation (a
development stage company) as of September 30, 1999, and the related statements
of operations, stockholders' equity (deficit) and cash flows for the years ended
September 30, 1999 and 1998 and from inception on October 3, 1994 through
September 30, 1999. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Sionix Corporation (a
development stage company) as of September 30, 1999 and the results of its
operations and its cash flows for the years ended September 30, 1999 and 1998
and from inception on October 3, 1994 through September 30, 1999 in conformity
with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 7 to the
financial statements, the Company is a development stage company with no
significant operating results to date and has suffered recurring losses which
raise substantial doubt about its ability to continue as a going concern.
Management's plans in regard to these matters are also described in Note 7. The
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

                        Notes to the Financial Statements
                               September 30, 1999

NOTE 1 - COMPANY ORGANIZATION AND BUSINESS ACTIVITY

         Sionix Corporation (the "Company") was incorporated in Nevada on
         October 3, 1994. The Company was formed to design, develop, and market
         an automatic water filtration system primarily for small water
         districts.

         The Company is in the development stage and its efforts through
         September 30, 1999 have been principally devoted to research and
         development, organizational activities, and raising capital. As of
         September 30, 1999, the Company has had $15,500 of revenues. The
         ultimate recovery of investments and costs is dependent on future
         profitable operations, which presently cannot be determined.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         a. Accounting Method

         The Company's financial statements are prepared using the accrual
         method of accounting. The Company has elected a September 30 year end.

         b. Cash Equivalents

         The Company considers all highly liquid investments with a maturity of
         three months or less when purchased to be cash equivalents.

         c. Property and Equipment

         Property and equipment are recorded at cost. Major additions and
         improvements are capitalized. Minor replacements, maintenance and
         repairs that do not increase the useful life of the assets are expensed
         as incurred. Depreciation of property and equipment is determined using
         the straight-line method over the expected useful lives of the assets
         as follows:

                        Description                     Useful Lives
                        -----------                     ------------
                 Computers and test equipment             5 years
                 Furniture and fixtures                   5 years

         d. Research and Development

         Research and development costs are expensed as incurred.

         The computation of basic loss per share of common stock is based on the
         weighted average number of shares outstanding at the date of the
         financial statements. Stock warrants and stock options have not been
         included as they are antidilutive.

         f. Provision for Income Taxes

         No provision for federal income taxes have been recorded due to net
         operating losses. The Company accounts for income taxes pursuant to
         FASB Statement No. 109. The Internal Revenue Code contains provisions
         which may limit the loss carryforwards available should certain events
         occur, including significant changes in stockholder ownership
         interests. Accordingly, the tax benefit of the loss carryovers is
         offset by a valuation allowance of the same amount. The loss
         carryforwards of approximately $4,000,000 will expire by the year 2014.

                        Notes to the Financial Statements
                               September 30, 1999


NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

         g. Estimates

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

         h. New Accounting Pronouncements

         The Financial Accounting Standards Board has also issued SFAS No. 130,
         "Reporting Comprehensive Income" and SFAS No. 131, "Disclosures about
         Segments of an Enterprise and Related Information." SFAS No. 130
         establishes standards for reporting and display of comprehensive
         income, its components and accumulated balances. Comprehensive income
         is defined to include all changes in equity except those resulting from
         investments by owners and distributions to owners. Among other
         disclosures, SFAS No. 130 requires that all items that are required to
         be recognized under current accounting standards as components of
         comprehensive income be reported in a financial statement that displays
         with the same prominence as other financial statements. SFAS No. 131
         supersedes SFAS No. 14 "Financial Reporting for Segments of a Business
         Enterprise." SFAS No. 131 establishes standards on the way that public
         companies report financial information about operating segments in
         annual financial statements and requires reporting of selected
         information about operating segments in interim financial statements
         issued to the public. It also establishes standards for disclosure
         regarding products and services, geographic areas and major customers.
         SFAS No. 131 defines operating segments as components of a company
         about which separate financial information is available that is
         evaluated regularly by the chief operating decision maker in deciding
         how to allocate resources and in assessing performance.

         SFAS No. 130 and 131 are effective for financial statements for periods
         beginning after December 15, 1997 and requires comparative information
         for earlier years to be restated. Because of the recent issuance of the
         standard, management has been unable to fully evaluate the impact, if
         any, the standard may have on future financial statement disclosures.
         Results of operations and financial position, however, will be
         unaffected by implementation of these standards.

                        Notes to the Financial Statements

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

         h. New Accounting Pronouncements (Continued)

         In February 1998, the Financial Accounting Standards Board ("FASB") has
         issued Statement of Financial Accounting Standard ("SFAS") No 132.
         "Employers' Disclosures about Pensions and other Postretirement
         Benefits" which standardizes the disclosure requirements for pensions
         and other Postretirement benefits and requires additional information
         on changes in the benefit obligations and fair values of plan assets
         that will facilitate financial analysis. SFAS No. 132 is effective for
         years beginning after December 15, 1997 and requires comparative
         information for earlier years to be restated, unless such information
         is not readily available. Management believes the adoption of this
         statement will have no material impact on the Company's financial
         statement.

         In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
         Instruments and Hedging Activities" which requires companies to record
         derivatives as assets or liabilities, measured at fair market value.
         Gains or losses resulting from changes in the values of those
         derivatives would be accounted for depending on the use of the
         derivative and whether it qualifies for hedge accounting. The key
         criterion for hedge accounting is that the hedging relationship must be
         highly effective in achieving offsetting changes in fair value or cash
         flows. SFAS No. 133 is effective for all fiscal quarters of fiscal
         years beginning after June 15, 1999. Management believes the adoption
         of this statement will have no material impact on the Company's
         financial statements.

         i. Advertising

         The Company follows the policy of charging the costs of advertising to
         expense as incurred.

NOTE 4 - INTANGIBLE ASSETS

         Intangible assets at September 30, 1999 consisted of the following:

            Patents issued and pending         $ 135,033
            Less accumulated amortization        (31,291)

                                               =========

         Amortization expense for the years ended September 30, 1999 and 1998
         was $9,002 and $99,154, respectively.

NOTE 5 - RELATED PARTY PAYABLES

         Pursuant to an acquisition agreement, the Company assumed various
         promissory notes originally signed in 1992 and 1993 totaling $50,000.
         The notes bear interest at 8% and were originally due in 1994.
         Management of the Company currently cannot locate the holder of the
         notes and consequently has not been able to settle the liabilities. The
         amount is being included as a current liability in the accompanying
         financial statements until management can locate the note holder and
         settle the debt. The liability is included in the related party
         payables.

         The Company has received other advances in the form of promissory notes
         from various shareholders and other related parties in order to pay
         ongoing operating expenses. As of September 30, 1999, $377,351 was due
         by the Company as a result of these promissory notes and the liability
         is considered to be current. Some of the notes bear interest at rates
         of 7% to 13.5%. All notes are due on demand and are unsecured.

NOTE 6 - STOCKHOLDERS' EQUITY

         During the year ended December 31, 1995, 414,200 shares of common stock
         were issued in return for notes receivable in the amount of $1,656,800.
         These notes were secured by the shares issued and were non-recourse.
         They had a stated interest rate of 6% and had maturity dates ranging
         from March 1, 1998 to September 7, 1998. During the year ended
         September 30, 1998, the shares originally issued in conjunction with
         the receivable were cancelled along with the corresponding subscription
         receivable.

NOTE 7 - GOING CONCERN

         The Company's financial statements are prepared using generally
         accepted accounting principles applicable to a going concern which
         contemplates the realization of assets and liquidation of liabilities
         in the normal course of business. However, the Company does not have
         significant cash or other material assets, nor does it have an
         established source of revenues sufficient to cover its operating costs
         and to allow it to continue as a going concern. It is the intent of the
         Company to generate revenue through the sales of its software and
         hardware products. In the opinion of management, sales of the Company's
         products, together with the proceeds of an offering of its common
         stock, will be sufficient for it to continue as a going concern.

NOTE 8 - COMMITMENTS

         Employment Agreement

         On January 1, 1998, the Company entered into an employment contract
         with an officer and director. The employment contract calls for
         payments of $7,083 per month to the officer through September 30, 2003.
         As a signing bonus, the officer was given the option to purchase
         2,200,000 shares of the Company's common stock at $0.001 per share.
         Accordingly, compensation expense of $220,000 has been recorded to
         reflect the discount from fair market value.

         Accounts Payable

         At September 30, 1999, the Company owed vendors amounts totaling
         $18,894 that are more than one year past due. One of the affected
         vendors has a judgment against the Company for the amount owed. As of
         September 30, 1999, the Company was making monthly payments on the
         amount owed to that vendor. It is the Company's intention to pay off
         all amounts owed as stated above by the end of fiscal 2000.

         Contingent Liabilities

         A certain company has asserted a claim against the Company for fees
         related to the hiring of an employee through that Company. According to
         the Company's legal counsel, the maximum exposure from this claim is
         $6,000. It is the Company's contention that it previously negotiated a
         settlement of this claim in which the Company was released of any
         related liability. The Company intends to vigorously fight this claim
         and expects no negative outcome as a result of this claim. Accordingly,
         the Company has made no provision in the financial statements relative
         to this claim.
