NOTE 1 - BUSINESS ACTIVITY

Sionix Corporation (the "Company") is a Nevada corporation incorporated in 1985.
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 have been principally
devoted to research and development, organizational activities, and raising
capital.

NOTE 2 - BASIS OF PRESENTATION

The accompanying unaudited financial statements of Sionix Corporation have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring adjustments) considered necessary for a fair presentation have been
included. Operating results for the interim periods are not necessarily
indicative of the results for any future period. These statements should be read
in conjunction with the Company's audited financial statements and notes thereto
for the fiscal year ended September 30, 2003.

NOTE 3 - RECENT PRONOUNCEMENTS

On May 15 2003, the FASB issued FASB Statement No. 150 ("SFAS 150"), ACCOUNTING
FOR CERTAIN FINANCIAL INSTRUMENTS WITH CHARACTERISTICS OF BOTH LIABILITIES AND
EQUITY. SFAS 150 changes the accounting for certain financial instruments that,
under previous guidance, could be classified as equity or "mezzanine" equity, by
now requiring those instruments to be classified as liabilities (or assets in
some circumstances) in the statement of financial position. Further, SFAS 150
requires disclosure regarding the terms of those instruments and settlement
alternatives. SFAS 150 affects an entity's classification of the following
freestanding instruments: a) Mandatorily redeemable instruments b) Financial
instruments to repurchase an entity's own equity instruments c) Financial
instruments embodying obligations that the issuer must or could choose to settle
by issuing a variable number of its shares or other equity instruments based
solely on (i) a fixed monetary amount known at inception or (ii) something other
than changes in its own equity instruments d) SFAS 150 does not apply to
features embedded in a financial instrument that is not a derivative in its
entirety. The guidance in SFAS 150 is generally effective for all financial
instruments entered into or modified after May 31, 2003, and is otherwise
effective at the beginning of the first interim period beginning after June 15,
2003. For private companies, mandatorily redeemable financial instruments are
subject to the provisions of SFAS 150 for the fiscal period beginning after
December 15, 2003. The adoption of SFAS No. 150 does not have a material impact
on the Company's financial position or results of operations or cash flows.

In December 2003, the Financial Accounting Standards Board (FASB) issued a
revised Interpretation No. 46, "Consolidation of Variable Interest Entities"
(FIN 46R). FIN 46R addresses consolidation by business enterprises of variable
interest entities and significantly changes the consolidation application of
consolidation policies to variable interest entities and, thus improves
comparability between enterprises engaged in similar activities when those
activities are conducted through variable interest entities. The Company does
not hold any variable interest entities.

fail materially to comply with the requirements of the agreement and such
failure is not cured within thirty (30) days after receipt of written notice
from the Investor or (4) the date occurring twenty-four (24) months after the

there under, or any similar successor statute (collectively, the "1933 Act"),
and applicable state securities laws.

date of issuance or (ii) issue or sell any warrant, option, right, contract,
call, or other security or instrument granting the holder thereof the right to
acquire Common Stock without consideration or for a consideration per share less
than the Bid Price on the date of issuance, provided, however, that the Investor
is given ten (10) days prior written notice and nothing in this section shall
prohibit the issuance of shares of Common Stock pursuant to existing contracts
or commitments, upon exercise of currently outstanding options or convertible
securities, or in connection with any acquisition. On the date hereof, the
Company shall obtain from each officer and director a lock-up agreement, as
defined below, in the form annexed hereto as Schedule 2.6(b) agreeing to only
sell in compliance with the volume limitation of Rule 144.

On each Advance Date the Company shall pay to the Investor, directly from the
gross proceeds held in escrow, an amount equal to four percent (4%) of the
amount of each Advance. Under the agreement, upon the execution of this
Agreement the Company was to issue to the Investor, shares of the Company's
Common Stock in an amount equal to Two Hundred Ninety Thousand Dollars
($290,000) divided by the Closing Bid Price on the Closing Date. Upon the
execution of the Agreement the Company was to issue to the Placement Agent
shares of the Company's Common Stock in an amount equal to Ten Thousand Dollars
($10,000) divided by the Closing Bid Price of the Company's Common Stock on the
date hereof.

shares was based upon market value of the shares at the time of the consummation
of the transaction. During the three month period ended December 31, 2003, the
Company amortized prepaid consulting amounting $33,897. During the three month
period ended March 31, 2004, the Company amortized prepaid consulting amounting
$31,200. As of March 31, 2004, the Company has prepaid consulting fees of
$72,800, reflected as unamortized consulting fees in the equity section of the
Balance Sheet.

The Company issued 3,333,333 shares into the escrow account in pursuant to the
Equity Line of Credit during the period ended December 31, 2003 (note 5).
6,295,947 shares were issued out of the escrow account to settle the equity line
of credit, amounting to $250,000.

The Company issued 11,500,000 shares into the escrow account pursuant to the
Equity Line of Credit during the three month period ended March 31, 2004 (note
5). 11,757,381 shares were issued out of the escrow account to settle the equity

of March 31, 2004.

As of December 31, 2003, the Company has 7,349,204 shares of common stock to be
cancelled. These shares were awarded to certain officers of the Company in the
prior years and were subject to restrictions and could not be sold until certain
conditions were met. On September 30, 2003, as the conditions in the agreements
were not met, the share awards were cancelled per the agreements between the
officers and the Company. These shares have been cancelled in the three month
period ending March 31, 2004.

During the period ended March 31, 2004, the Company received $33,900 in cash for
shares to be issued. This amount is reflected as Shares to be issued in the
equity section of the Balance Sheet.

NOTE 7 - EARNINGS PER SHARE

Earnings per share for six month periods ended March 31, 2004 and 2003 were
determined by dividing net income for the periods by the weighted average number
of both basic and diluted shares of common stock and common stock equivalents
outstanding. Weighted average number of shares used to compute basic and diluted
loss per share is the same since the effect of dilutive securities is
anti-dilutive.

NOTE 8 - RECLASSIFICATIONS

Certain prior period amounts have been reclassified to conform to the period
ended March 31, 2004 presentation.

NOTE 9 - LITIGATION, COMMITMENT & EXTRAORDINARY ITEM

LITIGATION:

The lawsuit which was filed by the Company against its former President,
Dascore, LLC, an entity controlled by the former President and in a business
related to that of the Company; and a former officer and director of the Company
(the "Defendants"), was settled. The Company alleged, that the Defendants had
(1) infringed on certain patents owned by the Company, through knowledge gained
in their former positions; (2) sold or attempted to sell technology owned by the
Company and covered by patents; (3) conspired to convert technology, money and
equipment owned by the Company to pay personal expenses, and (4) defrauded the
Company and breached their fiduciary duties in connection with their departure
by retention of property owned by the Company. As a result of this settlement,
the Company recorded a gain of $79,999 in the year ended September 30, 2002, for
the settlement award. The Company also recorded $17,618 as an extraordinary gain
on settlement of debts for forgiven amount of note payable as per the
settlement. In addition, all of outstanding stocks held by the defendants
totaling 7,533,701 shares were returned to the Company and cancelled by the
Company. Certain defendants appealed the settlement, but the judgment of the
court was affirmed on January 21, 2003.

The Company's counsel was served with a motion in the Federal case by the
attorneys for Mr. Wade Cowart. The motion seeks to have the Company pay damages
of up to $100,000 in connection with a restraining order that the Federal court
previously issued against Mr. Cowart. The Company posted the potential maximum
liability of $100,000 as security bond. Mr. Cowart made motions seeking recovery
on the bond posted by the Company for the original injunction. The Company paid
$100,000 to the Court during the quarter ended March 31, 2004 towards the
settlement of the case.

An action filed by the Company for professional negligence, malpractice, breach
of fiduciary duty and breach of contract against Gilliam, Duncan & Harms, its
previous patent counsel, was settled in June 2002. The complaint alleged that
the patent attorneys represented the Company and Jack Moorehead, former
President of the Company, contemporaneously and failed to advise the corporation
of the inherent conflict of interest in representing both parties. The action
further alleged the patent attorneys aided Moorehead and others in
misappropriating the Company's intellectual property and trade secrets. The
action went to trial, and in December 2001 a minute order was issued announcing
a judgment in favor of Sionix against the defendants. Harms filed a voluntary
bankruptcy on December 27, 2001. Sionix filed a Complaint in the U.S. bankruptcy
court, alleging claims against Harms and disputing the dischargeability of the
debts owed by Harms to Sionix. Upon settlement agreement, the Company received
$200,000 as a full and final settlement for this Complaint. The Company has
recorded this settlement amount of $200,000 as a gain on settlement in the
financial statement for the year ended September 30, 2002. In connection with
this case, the Company also received $1,500 as a settlement for dismissal of
certain parties from this action.

The Company was the defendant in a collection action brought by a law firm that
had previously represented it, Murphey & Murphey v. Sionix Corporation. The law
firm sued the Company for the collection of $156,618 in legal fees. The Company
has filed a cross-complaint alleging, among other things, malpractice and breach
of fiduciary duty. On September 25, 2002, the Company settled the case with
payment terms of $165,000 resulting in a settlement loss of $8,382. The Company
paid $145,000 in the fiscal year 2002 and paid $20,000 in 2003.

In July 2003, an action was filed by a group of the Company's shareholders
located in San Diego County, California, alleging a variety of international and
negligent acts on the part of the Company, its officers and directors. The
action was voluntarily dismissed by the plaintiffs, without prejudice, in April
2004.

In August 2003, an action was filed in Kansas by a group of the Company
shareholders located in several states, alleging a variety of international and
negligent acts on the part of the Company, its officers and directors. Though
originally filed in the state court, the case was moved to the United States
District Court, in and for the District of Kansas. In October 2003, the Company
and its co-defendants filed a motion to dismiss the Kansas case. On October 24,
2003, the Kansas shareholder plaintiffs voluntarily dismissed their action.
Costs were assessed against the plaintiffs by the court.

NOTE 10- GOING CONCERN

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. This basis of accounting contemplates
the recovery of the Company's assets and the satisfaction of its liabilities in
the normal course of business. Through March 31, 2004, the Company had incurred
cumulative losses of $13,178,867, including a loss of $691,387 for the six month
period ended March 31, 2004. The Company's successful transition from a
development stage company to attaining profitable operations is dependent upon
obtaining financing adequate to fulfill its research and development activities,
production of its equipment and achieving a level of revenues adequate to
support the Company's cost structure. Management's plan of operations
anticipates that the cash requirements for the next twelve months will be met by
obtaining capital contributions through the sale of common stock and cash flow
from operations. However, there is no assurance that the Company will be able to
implement its plan. In that regard, on September 17, 2002, the Company entered
into an agreement with an investor, pursuant to which the Investor will purchase
the Company's Common Stock, par value $.001 per share for an aggregate price of
up to Seven Million Five Hundred Thousand Dollars ($7,500,000) (Note 5).

Item 2.     Management's Discussion and Analysis or Plan of Operation

         Statements contained in this Quarterly Report on Form 10-QSB include
"forward-looking statements" within the meaning of Section 27A of the Securities
Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
Forward-looking statements involve known and unknown risks, uncertainties and
other factors which could cause the actual results of the Company, performance
(financial or operating) or achievements expressed or implied by such
forward-looking statements not to occur or be realized. Such forward-looking
statements generally are based upon the Company's best estimates of future
results and activity in the marketplace, and are based upon current conditions
and the most recent results of operations. Forward-looking statements may be
identified by the use of forward-looking terminology such as "may," "will,"
"expect," "believe," "estimate," "anticipate," "intends," "potential,"
"opportunity" or similar terms, or variations of those terms. See the Company's
most recent Annual Report on Form 10-KSB for a description of certain of the
known risks and uncertainties of the Company.

Results of Operations (Three Months Ended March 31, 2004 Compared to Three
--------------------------------------------------------------------------
Months Ended March 31, 2003).
-----------------------------

         General and administrative expenses in the three months ended March 31,
2004 decreased by $76,207, from $322,058 in the prior period to $245,851 in the
current period. The decrease is principally due to reduced staffing and lower
legal expense. Research and development costs decreased by $49,863, principally
due to the completion of most research and development activities relating to
the Company's products. The operating loss for the quarter decreased by
$120,786, due principally to the reduced general and administrative expenses and
research and development expense, offset somewhat by increased depreciation
expense. Net loss for the current quarter of $356,954 includes a $100,000
expense relating to settlement of a legal claim.

Results of Operations (Six Months Ended March 31, 2004 Compared to Six Months
-----------------------------------------------------------------------------
Ended March 31, 2003).
----------------------

         General and administrative expenses in the six months ended March 31,
2004 decreased by $306,101, from $856,179 in the prior period to $550,078 in the
current period. The decrease is principally due to reduced staffing and lower
legal expense. Research and development costs decreased by $39,330, principally
due to the completion of most research and development activities relating to
the Company's products in the current quarter. The operating loss for the period
decreased by $334,603, due principally to the reduced general and administrative
expenses and research and development expense, offset somewhat by increased
depreciation expense. Net loss for the current period of $691,387 includes a
$100,000 expense relating to settlement of a legal claim.

Liquidity and Capital Resources.
--------------------------------

         On March 31, 2004, the Company had cash and cash equivalents of
approximately $3,493. The principal source of liquidity has been sales of
securities and loans from shareholders. Management anticipates that additional
capital will be required to finance the Company's operations.

                                       3


<PAGE>

         During 2002 the Company entered into an Equity Line of Credit Agreement
with Cornell Capital, L. P. which allows the Company, at its option, to draw
funds from time to time in exchange for the issuance of shares, up to a maximum
of $7,500,000. The Company believes that available proceeds from the Equity Line
of Credit Agreement, proceeds from private placements, and possible cash flow
from the sale of products will be sufficient to finance the Company's
operations. However, the Company has no other commitments for financing, and
there can be no assurance that such financing will be available or that the
Company will not encounter unforeseen difficulties that may deplete its capital
resources more rapidly than anticipated. Also, the Company may not be able to
generate revenues from operations during the quarter.

         As of March 31, 2004, the Company had an accumulated deficit of
$13,178,867. 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 developmental business enterprise, many of which the
Company cannot control.

Item 3. Controls and Procedures.

         Under the supervision and with the participation of our Chief Executive
Officer and Chief Financial Officer, we conducted an evaluation of our
disclosure controls and procedures, as such term is defined under Rule 13a-14(c)
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), within 90 days of the filing date of this report. Based on this
evaluation, our Chief Executive Officer and the Chief Financial Officer
concluded that the Company's disclosure controls and procedures are effective.
Disclosure controls and procedures are designed to ensure that information
required to be disclosed in reports under the Exchange Act are processed and
reported within the time periods specified by law. The design of any such system
of controls is based in part on assumptions about the likelihood of future
events, and there can be no assurance that any such system of controls will
succeed in all circumstances.

         Since the date of the evaluation described above, there have been no
significant changes in our internal controls or in other factors that could
significantly affect these controls.
