Item 8A.  Controls and Procedures, page 15
- ------------------------------------------

1.   COMMENT   While it appears that you may have conducted an evaluation of
               internal control over financial reporting, your disclosure about
               that evaluation is not complete and you have not provided an
               appropriate conclusion as required by Item 308T(a)(3) of
               Regulation S-B. We note that the first sentence of the second
               paragraph states that you conducted an evaluation of internal
               control over financial reporting, and the third sentence of that
               paragraph expresses a conclusion on the effectiveness of
               disclosure controls and procedures. Please note that disclosure
               controls and procedures and internal control over financial
               reporting are not interchangeable concepts. Your filing should
               present management's conclusion on the effectiveness of
               disclosure and control and procedures as required by Item 307 of
               Regulation S-B and should also separately present management's
               conclusion on the effectiveness of internal control over
               financial reporting as required by Item 308T(a)(3) of Regulation
               S-B. Accordingly, please revise your filing for the following.

               o    Please provide management's evaluation and conclusion on the
                    effectiveness of disclosure controls and procedures as of
                    the end of the period covered by the annual report as
                    required by Item 307 of Regulation S-B and Exchange Act Rule
                    13a-15(b). We also refer you to the definition of disclosure
                    controls and procedures as set forth in Exchange Act Rule
                    13a-15(e).



               o    Please revise to separately provide management's evaluation
                    and conclusion on the effectiveness of internal control over
                    financial reporting as of the end of the period covered by
                    the annual report as required by Item 308T(a)(3) of
                    Regulation S-B and Exchange Act Rule 13a-15(c). We also
                    refer you to the definition of internal control over
                    financial reporting as set forth in Exchange Act Rule
                    13a-15(f).
               o    With respect to the evaluation of internal control over
                    financial reporting, please disclose the framework used to
                    evaluate the effectiveness of internal control over
                    financial reporting. We refer you to Item 308T(a)(2) of
                    Regulation S-B.
               o    In the first paragraph you provide a partial definition of
                    internal control over financial reporting. In your revised
                    disclosure, please provide the complete definition of
                    internal control over financial reporting as set forth in
                    Exchange Act Rule 13a-159f). Alternatively, you may define
                    internal control over financial reporting with a reference
                    to Exchange Act Rule 13a-15(f) without further attempt to
                    define the concept.
               o    In the first sentence of the second paragraph, please note
                    that the requirement to evaluate internal control over
                    financial reporting is set forth in Exchange Act Rule
                    13a-15(c). In that regard, Exchange Act Rule 13a-15(b),
                    which is currently referenced in your disclosure, requires
                    that you perform the separate evaluation of disclosure
                    controls and procedures. Please ensure that Exchange Act
                    Rule references are correct in your revise disclosures
               o    With respect to the disclosure that you are not yet required
                    to present an auditor report on the effectiveness of
                    internal control over financial reporting, please revise to
                    insert the word "not" between the words "was" and "subject"
                    in the second sentence. Refer to Item 308T(a)(4) of
                    Regulation S-B.

     ANSWER:   The Company will remove the first three paragraphs of ITEM 8A
               CONTROLS AND PROCEDURES and replace them with the following
               statements in the amended 10-KSB to be filed:

               "Management's Report on Internal Control over Financial
               Reporting:

               Our Company's management is responsible for establishing and
               maintaining adequate internal control over financial reporting
               (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act)
               for our company. Our Company's internal control over financial
               reporting is designed to provide reasonable assurance, not
               absolute assurance, regarding the reliability of financial
               reporting and the preparation of financial statements for
               external purposes in accordance with generally accepted
               accounting principles in the United States of America. Internal
               control over financial reporting includes those policies and
               procedures that: (i) pertain to the maintenance of records that,
               in reasonable detail, accurately and fairly reflect the
               transactions and dispositions of our Company's assets; (ii)
               provide reasonable assurance that transactions are recorded as
               necessary to permit preparation of financial statements in
               accordance with generally accepted accounting principles in the
               United States of America, and that our Company's receipts and
               expenditures are being made only in accordance with
               authorizations of our management and directors; and (iii) provide
               reasonable assurance regarding prevention or timely detection of
               unauthorized acquisition, use or disposition of our assets that
               could have a material effect on the financial statements.



               Because of its inherent limitations, internal control over
               financial reporting may not prevent or detect misstatements.
               Projections of any evaluation of effectiveness to future periods
               are subject to the risk that controls may become inadequate
               because of changes in conditions, or that the degree of
               compliance with the policies or procedures may deteriorate.

               As required by Rule 13a-15(c) promulgated under the Exchange Act,
               our management, with the participation of our Chief Executive
               Officer ("CEO") and Chief Financial Officer ("CFO"), evaluated
               the effectiveness of our internal control over financial
               reporting as of October 31, 2008. Management's assessment took
               into consideration the size and complexity of the company and was
               based on criteria set forth by the Committee of Sponsoring
               Organizations of the Treadway Commission in Internal Control over
               Financial Reporting --Guidance for Smaller Public Companies. In
               performing the assessment, management has concluded that our
               internal control over financial reporting was effective as of
               October 31, 2008.

               This annual report does not include an attestation report of the
               Company's registered public accounting firm regarding internal
               control over financial reporting. Management's report was not
               subject to attestation by the Company's registered public
               accounting firm pursuant to temporary rules of the Securities and
               Exchange Commission ("SEC") that permit the Company to provide
               only management's report in this annual report.

               Evaluation of disclosure controls and procedures:

               Disclosure controls are controls and procedures that are designed
               to ensure that information required to be disclosed in our
               reports filed under the Exchange Act is recorded, processed,
               summarized and reported, within the time periods specified in the
               SEC's rules and forms. Disclosure controls and procedures
               include, without limitation, controls and procedures designed to
               ensure that information required to be disclosed by a Company in
               the reports that it files or submits under the Exchange Act is
               accumulated and communicated to the company's management,
               including its principal executive and principal financial
               officers, or persons performing similar functions, as appropriate
               to allow timely decisions regarding required disclosure. Our
               management carried out an evaluation under the supervision and
               with the participation of our CEO and CFO, of the effectiveness
               of the design and operation of our disclosure controls and
               procedures pursuant to Rules 13a-15(e) and 15d-15(e) under the
               Securities Exchange Act of 1934 ("Exchange Act"). Based upon that
               evaluation, the Company's CEO and CFO have concluded that the
               Company's disclosure controls and procedures were not effective
               as of October 31, 2008, due to management's failure to include
               its report on internal control over financial reporting in the
               Form 10-KSB as required."

2.   COMMENT   As a related matter, please consider whether management's failure
               to provide its conclusion on the effectiveness of internal
               control over financial reporting impacts its conclusion regarding
               the effectiveness of your disclosure controls and procedures as
               of the end of the fiscal year. In particular, please consider the
               definition of disclosure controls and procedures provided in Rule



               13a-15(e), which indicates that effective controls and procedures
               would ensure that information required to be disclosed by the
               issuer is recorded, processed, summarized and reported within the
               time periods specified in the Commission's rules and forms. In
               addition, as discussed in Compliance and Disclosure
               Interpretation 115.02, which you can find at
               http:www.sec.gov/division/corpfin/guidance/regs-kinterp.htm,
               failure to file management's report on Internal Control over
               Financial Reporting rendered your annual report materially
               deficient and also rendered the company not timely or current in
               its Exchange Act Reporting. In light of these facts, please
               explain how you could conclude that disclosures and procedures
               were effective. Alternatively, please amend the Form 10-KSB to
               disclose management's revised conclusion on the effectiveness of
               your disclosure controls and procedures, i.e. that DC&P were not
               effective as of the end of the fiscal year.

     ANSWER:   The Company will include the following statement in the amended
               10-KSB to be filed:

               "Evaluation of disclosure controls and procedures:

               Disclosure controls are controls and procedures that are designed
               to ensure that information required to be disclosed in our
               reports filed under the Exchange Act is recorded, processed,
               summarized and reported, within the time periods specified in the
               SEC's rules and forms. Disclosure controls and procedures
               include, without limitation, controls and procedures designed to
               ensure that information required to be disclosed by a company in
               the reports that it files or submits under the Exchange Act is
               accumulated and communicated to the company's management,
               including its principal executive and principal financial
               officers, or persons performing similar functions, as appropriate
               to allow timely decisions regarding required disclosure. Our
               management carried out an evaluation under the supervision and
               with the participation of our CEO and CFO, of the effectiveness
               of the design and operation of our disclosure controls and
               procedures pursuant to Rules 13a-15(e) and 15d-15(e) under the
               Securities Exchange Act of 1934 ("Exchange Act"). Based upon that
               evaluation, the Company's CEO and CFO have concluded that the
               Company's disclosure controls and procedures were not effective
               as of October 31, 2008, due to management's failure to include
               its report on internal control over financial reporting in the
               Form 10-KSB as required."

3.   COMMENT   Under "Changes in Internal Controls over Financial Reporting,"
               please revise to state whether there was any change in internal
               control over financial reporting during the most recent quarter
               that has materially affected or is reasonably likely to
               materially affect internal control over financial reporting. We
               refer you to the language in Item 308T(b) of Regulation S-B.

     ANSWER:   The Company will remove the existing statement in ITEM 8A
               CONTROLS AND PROCEDURES and will include the following statement
               in the amended 10-KSB to be filed, "There has been no change in
               the Company's internal control over financial reporting for the
               quarter ended October 31, 2008 that materially affected, or is
               reasonably likely to materially affect, our internal control over
               financial reporting."

4.   COMMENT   We reference the second paragraph of the audit report, which
               states that "we conducted our audits in accordance with the
               standards of the Public Company Accounting Oversight Board,
               generally accepted in the United States of America." Please have
               your auditors revised their audit report to refer to the
               standards of the Public Company Accounting Oversight Board
               (United States), consistent with PCAOB Auditing Standard No. 1.

     ANSWER:   The Company has received the updated audit opinion letter and
               will include it with its amended 10-KSB.

- -------------------------------------------------

5.   COMMENT   We note your disclosure "the Company is in arrears on a
               substantial number of its financial obligations." Please tell us
               and revise future filings to clarify whether you are in default
               of any of your obligations or borrowings.

     ANSWER:   The Company will include in future filings a general status of
               liabilities in arrears, if appropriate, and whether the Company
               has received formal notice of default regarding any of those
               liabilities. Additionally, it should be noted that the Company
               did disclose the existence of litigation related to a liability
               in arrears in Note 11 of its financial statements.

Note 12.  Going Concern, page F-16
- ----------------------------------

6.   COMMENT   We note that you will require $2,500,000 to satisfy your current
               budgetary projections. Please tell us and disclose in Note 12 and
               the liquidity section of MD&A in future filings how you plan to
               raise the required funds.

     ANSWER:   In future filings the Company will disclose in several locations
               its fundraising status related to budgetary needs, as
               appropriate. For the current FY2008 Form 10-KSB, the Company
               included the following in the RISK FACTORS section:

               "LACK OF ADDITIONAL FINANCING COULD PREVENT US FROM OPERATING
               PROFITABLY WHICH, EVENTUALLY, COULD RESULT IN A TOTAL LOSS OF OUR
               BUSINESS.

               Since our inception, we have funded our operations through
               revenue from the sale of our products, borrowings and financings.
               Current funds available to CDEX may not be adequate for us to be
               competitive in the areas in which we intend to operate, and we
               have no arrangements or commitments for ongoing funding. If
               funding is insufficient at any time in the future, we may not be
               able to grow revenue, take advantage of business opportunities or
               respond to competitive pressures. The unavailability of funding
               could prevent us from producing additional revenues or ever
               becoming profitable. Our continued operations, as well as the
               successful implementation of our business plan, may therefore
               depend upon our ability to raise additional funds through bank
               borrowings or equity or debt financing over the next twelve
               months. We continue to seek prospective investors who may provide
               some of this funding. However, such funding may not be available
               when needed or may not be available on favorable terms. Certain
               family members or business entities of our management team have
               loaned funds to CDEX on an as-needed basis although there is no
               definitive or legally binding arrangement to do so. If we do not
               produce revenues and become profitable, eventually, we will be
               unable to sustain our business."

7.   COMMENT   Please tell us how you plan to account for the modifications
               relating to Gemini Master Fund. Specifically, we note that you
               reset the conversion provisions and the exercise price of 30% of
               the Transaction Document warrants.

     ANSWER:   The Company is currently evaluating the impact the modifications
               relating to the Gemini Master Fund note will have on its
               financial statements and will disclose that impact in the next
               quarterly statement following the completion of the evaluation.

Exhibits 31.1 and 31.2
- ----------------------

8.   COMMENT   We note that you omitted a portion of the introductory language
               in paragraph 4 of Item 301(b)(31)(i) of Regulation S-K and that
               you omitted paragraph 4(b) of Item 601(b)(31)(i) of Regulation
               S-K, both of which refer to internal control over financial
               reporting. Please file an amendment to the Form 10-KSB to include
               certifications that include the required paragraphs. In addition,
               we note your reference to the Form 10-K in the first paragraph of
               the certification of your Chief Financial Officer. Since you have
               filed a Form 10-KSB please revise the reference in the first
               paragraph.

     ANSWER:   The Company will include the introductory language in paragraph 4
               of Item 301(b)(31)(i) of Regulation S-K and paragraph 4(b) of
               Item 601(b)(31)(i) of Regulation S-K in the certifications with
               the amended 10KSB. Additionally, the first paragraph of the
               certification of our Chief Financial Officer will be amended to
               reference the Form 10-KSB.

9.  COMMENT:   We also note that the identification of the certifying
               individuals at the beginning of the certifications required by
               Exchange Act Rule 13a-14(a) also includes the title of the
               certifying individual. In future filings, the identification of
               the certifying individual at the beginning of each certification
               should be revised so as not to include such individuals' title.

     ANSWER:   In future filings, The Company will not include the title of

               required by Exchange Act Rule 13a-14(a).

    COMMENT:   We urge all persons who are responsible for the accuracy and
               adequacy of the disclosure in the filing to be certain that the
               filing includes all information required under the Securities
               Exchange Act of 1934 and that they have provided all information
               investors require for an informed investment decision. Since the
               company and its management are in possession of all facts
               relating to a company's disclosure, they are responsible for the
               accuracy and adequacy of the disclosures they have made.

               In connection with responding to our comments, please provide, in
               writing, a statement from the company acknowledging that:

               >    the company is responsible for the adequacy and accuracy of
                    the disclosure in the filing



               >    staff comments or changes to disclosure in response to staff
                    comments do not foreclose the Commission from taking any
                    action with respect to the filing; and

               >    The company may not assert staff comments as a defense in
                    any proceeding initiated by the Commission or any person
                    under the federal securities laws of the United States.
