                          (A Development Stage Company)
                 Notes to the Consolidated Financial Statements
                      June 30, 2004, and December 31, 2003


NOTE 3 -      GOING CONCERN

              The Company's consolidated 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. The
              Company has incurred significant losses from its inception through
              June 30, 2004, which have resulted in an accumulated deficit of
              $18,467,999 at June 30, 2004. The Company does not have an
              established source of funds sufficient to cover its operating
              costs, has a working capital deficit of approximately $2,491,000,
              and has relied exclusively on debt and equity financing.
              Accordingly, there is substantial doubt about its ability to
              continue as a going concern.

              Continuation of the Company as a going concern is dependent upon
              obtaining additional capital, obtaining the requisite approvals
              from the FDA and/or the EU for the marketing of ozone-related
              products and equipment, and ultimately, upon the Company's
              attaining profitable operations. The Company will require a
              substantial amount of additional funds to complete the development
              of its products, to establish manufacturing facilities, to build a
              sales and marketing organization and to fund additional losses,
              which the Company expects to incur over the next several years.
              However, if the Company is unsuccessful in raising necessary
              capital in the next month, it will most likely be forced to cease
              operations.

              Because ozone-generation for the purposes of interfacing with
              blood and blood products is regarded as a new drug delivery
              system, the Company is precluded from selling or distributing its
              drug or the Medizone Technology in the United States until after
              FDA approval has been granted. In order to obtain FDA approval,
              the Company will be required to submit a New Drug Application
              ("NDA") for review by the FDA and provide medical and scientific
              evidence sufficient to demonstrate that the drug and the Medizone
              Technology have been successfully used in pre-clinical studies
              followed by three phases of well-controlled clinical studies using
              human volunteer subjects. The FDA will not grant an NDA unless the
              application contains sufficient medical evidence and data to
              permit a body of qualified and experienced scientists to conclude
              that the new drug product is safe and effective for its
              recommended and proposed medical uses. Historically, the FDA has
              held a strong bias against treating humans with ozone, due largely
              to issues of safety.

              In order to initiate the first phase (i.e., Phase I) of human
              clinical trials required as part of an NDA, an applicant must
              submit to the FDA an application for an Investigational New Drug
              Exemption ("IND"), which contains adequate information to satisfy
              the FDA that human clinical trials can be conducted without
              exposing the volunteer human subjects to an unreasonable risk of
              illness or injury. The Company submitted an IND application
              (assigned to the Company by its former president) to the FDA on
              October 6, 1985, and requested FDA approval to commence human
              clinical trials using ozone-oxygen to inactivate HIV. The FDA
              deemed the IND application to be incomplete, and required the
              Company to conduct additional animal studies prior to commencing a
              large animal study and human trials. In September 1994, after not
              receiving responses to requests for information from the Company,
              the FDA inactivated the Company's IND. The Company has no present
              plans to commence a large animal study, which would require, as a
              precursor, additional small animal and laboratory work.
              Accordingly, there can be no assurance that the Company's IND
              application will ever be reopened. Until an NDA has been granted
              to the Company, it may not distribute ozone-generating devices in
              the United States, except to researchers who agree to follow FDA
              guidelines, and provided the devices are labeled as
              "Investigational Devices."

                          (A Development Stage Company)
                 Notes to the Consolidated Financial Statements
                      June 30, 2004, and December 31, 2003

NOTE 3 -  GOING CONCERN (Continued)

              Because ozone has been used to treat humans in Europe for at least
              30 years, the EU is more accepting of human clinical trials of
              ozone therapies being conducted than is the United States.
              Accordingly, management believes that the Company should pursue
              the option of conducting human clinical trials in Europe, using
              stringent protocols that will meet EU standards, with a view to
              utilizing the results of such trials in an effort to obtain EU
              approval, to market the product in Europe and to reopen the
              Company's FDA file. The Company estimates that 90% of its
              potential market is outside the United States.

              The management of the Company intends to seek additional funding
              which will be utilized to fund additional research and continue
              operations. The Company recognizes that if it is unable to raise
              additional capital in the near future, it may find it necessary to
              substantially reduce or cease operations.

              The ability of the Company to continue as a going concern is
              dependent on its ability to successfully accomplish the plan
              described in the preceding paragraphs and eventually attain
              profitable operations. The consolidated financial statements do
              not include any adjustments relating to the recoverability and
              classification of asset carrying amounts or the amount and
              classification of liabilities that might result from the outcome
              of these uncertainties.

NOTE 4 -      OUTSTANDING WARRANTS AND OPTIONS

              On February 23, 2004, and again on April 12, 2004 and August 10,
              2004, the Board of Directors of the Company agreed to extend the
              expiration date on certain outstanding warrants and options to
              purchase common stock. At June 30, 2004, the following warrants
              were outstanding:

              The Company estimates the fair value of each stock award or
              expiration extension at the grant date or extension date by using
              the Black-Scholes option pricing model pursuant to FASB Statement
              123, "Accounting for Stock-Based Compensation." Under the
              provisions of SFAS 123, no additional expense was recorded at
              February 23, 2004, April 12, 2004, or August 10, 2004, under the
              Black-Scholes option pricing model for these warrant and option
              extensions.

NOTE 5 -      COMMITMENTS AND CONTINGENCIES

              The Company is subject to certain claims and lawsuits arising in
              the normal course of business. In the opinion of management,
              uninsured losses, if any, resulting from the ultimate resolution
              of these matters will not have a material effect on the Company's
              financial position, results of operations, or cash flows.

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


         The following discussion and analysis of financial condition and plan
of operation should be read in conjunction with the unaudited Condensed
Consolidated Financial Statements and Notes thereto appearing elsewhere in this
Quarterly Report on Form 10-QSB.


         Medizone International, Inc., a Nevada corporation ("Medizone"),
organized in 1986, is a development stage company. To date our principal
business has been limited to (i) seeking regulatory approval of a precise
mixture of ozone and oxygen called MEDIZONE(R) (sometimes referred to in this
report as the "Drug"), and our process of inactivating lipid enveloped viruses
for the intended purpose of decontaminating blood and blood products and
assisting in the treatment of certain diseases; and (ii) developing or acquiring
the related technology and equipment for the medical application of our
products, including our drug production and delivery system (the "Medizone
Technology").


         The Drug is intended to be used as a therapeutic drug in humans to
inactivate certain viruses, and thereby afford a treatment for certain viral
diseases including Human Immunodeficiency Virus (the AIDS-related virus),
Hepatitis B, Hepatitis C, Epstein-Barr, herpes, and cytomegalovirus, and to
decontaminate blood and blood products.


Results of Operations


         From its inception in January 1986, Medizone International has been a
development stage company primarily engaged in research into the medical uses of
ozone. We have not generated, and cannot predict when or if we will generate
revenues or sufficient cash flow to fund our continuing operations. If we fail
to obtain additional funding within the next month or two, we will be forced to
suspend or permanently cease operations, and may need to seek protection under
United States bankruptcy laws.


Three Months Ended June 30, 2004 and 2003


         There were no sales during the quarters ended June 30, 2004 or 2003. We
made no expenditures for research and development during the quarters ended June
30, 2004 and 2003. Since inception we have spent a total of $2,685,788 for
research and development.


         General and administrative expenses in the quarter ended June 30, 2004,
were $103,828 compared to $140,032 during the same period in 2003. These
expenses include professional fees, payroll, insurance costs, and travel
expenses.


         Interest expense accrued during the three months ended June 30, 2004
and 2003, was $6,412 and $5,914, respectively.


Six Months Ended June 30, 2004 and 2003


         There were no sales during the six months ended June 30, 2004 or 2003.
We made no expenditures for research and development during the six months ended
June 30, 2004 and 2003. Since inception we have spent a total of $2,685,788 for
research and development.


         General and administrative expenses during the six months ended June
30, 2004, were $198,191 compared to $235,349 during the same period in 2003. The
reduction in these expenses reflects the limited business conducted by the
Company during the period as efforts to obtain financing continued. These
expenses include professional fees, payroll, insurance costs, and travel
expenses.


         Interest expense accrued during the six months ended June 30, 2004 and
2003, was $12,326 and $11,828, respectively.


Liquidity and Capital Resources


         At June 30, 2004, we had a working capital deficiency of $2,491,273 and
stockholders' deficit of $2,491,273. At December 31, 2003, we had a working
capital deficiency of $2,294,937 and stockholders' deficit of $2,293,726.


         Net cash used in operating activities during the six months ended June
30, 2004, was $9,075. Cash of $8,151 was provided during the six months ended
June 30, 2004 from shareholder/director advances. During the six months ended
June 30, 2003, there was net cash used in operating activities of $28,271. Cash
of $28,199 was provided in the first six months of 2003 primarily by the sale
and issuance of common stock.


                                        9

<PAGE>

         The Company continues to require additional funding to enable it to
operate and to fund research necessary to make the appropriate regulatory
application and continue operations. We expect that these funds will be provided
by the sale of our securities. Because we have no current significant
operations, have an operating loss and are dependent on financing to continue
operations, our financial statements contain a going concern qualification. If
we are unable to raise additional capital in the next month or two, it will be
necessary to cease operations.


Forward-Looking Statements and Risks Affecting the Company


         The statements contained in this Report on Form 10-QSB that are not
purely historical are "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995 and Section 21E of the
Securities Exchange Act. These statements regard our expectations, hopes,
beliefs, anticipations, commitments, intentions and strategies regarding the
future. They may be identified by the use of the words or phrases "believes,"
"expects," "anticipates," "should," "plans," "estimates," and "potential," among
others. Forward-looking statements include, but are not limited to, statements
contained in Management's Discussion and Analysis of or Plan of Operation
regarding our financial performance, revenue and expense levels in the future
and the sufficiency of existing assets to fund future operations and capital
spending needs. Actual results could differ materially from the anticipated
results or other expectations expressed in such forward-looking statements for
the reasons detailed in our Annual Report on Form 10-KSB for the year ended
December 31, 2003 under the headings "Description of Business" and "Risk
Factors." The fact that some of the risk factors may be the same or similar to
past reports filed with the Securities and Exchange Commission means only that
the risks are present in multiple periods. We believe that many of the risks
detailed here and in our SEC filings are part of doing business in the industry
in which we operate and compete and will likely be present in all periods
reported. The fact that certain risks are endemic to the industry does not
lessen their significance. The forward-looking statements contained in this
report are made as of the date of this Report and we assume no obligation to
update them or to update the reasons why actual results could differ from those
projected in such forward-looking statements. Among others, risks and
uncertainties that may affect our business, financial condition, performance,
development, and results of operations include:

     o    Rigorous  government  scrutiny  and  regulation  of our  products  and
          planned products;

     o    Potential  effects of adverse  publicity  regarding  ozone and related
          technologies or industries;

     o    Failure to sustain or manage growth  including the failure to continue
          to develop new products; and

     o    The ability to obtain needed financing.


Item 3.    Controls and Procedures

         Our principal executive and principal financial officers have
participated with management in the evaluation of effectiveness of the controls
and procedures required by paragraph (b) of Rule 13a-15 or Rule 15d-15 under the
Exchange Act as of the end of the period covered by this report. Based on that
evaluation, our principal executive and principal financial officers believe
that our disclosure controls and procedures (as defined in Rule 13a-15(e) or
Rule 15d-15(e) under the Exchange Act) are effective as of the end of the period
covered by the report. There have been no changes in our internal controls that
have materially affected, or are reasonably likely to materially affect, our
internal controls over financial reporting during the period covered by this
report.
