                           FIFTH WAIVER AND AMENDMENT
                           --------------------------

     This FIFTH WAIVER AND AMENDMENT ("Amendment") is made effective the 1st day
of October, 2009, by and between CDEX Inc., a Nevada corporation ("Company"),
and GEMINI MASTER FUND, LTD., a Cayman Islands company ("Holder").

                              W I T N E S S E T H:
                              - - - - - - - - - -

          WHEREAS, pursuant to that certain Securities Purchase Agreement
("Purchase Agreement") dated as of June 25, 2008 by and between the Company and
the Holder, on or about such date the Company sold and issued to the Holder (i)
a 12% Senior Convertible Note ("Note"), which Note is convertible into shares of
common stock of the Company, $0.005 par value per share ("Common Stock"), and
(ii) a Common Stock Purchase Warrant to purchase up to 2,717,391 shares of
Common Stock ("Warrant");

          WHEREAS, by agreements dated December 18, 2008 and February 1, May 1
and June 1, 2009, entitled Waiver and Amendment ("First Amendment"), Second
Waiver and Amendment ("Second Amendment"), Third Waiver and Amendment ("Third
Amendment"), and Fourth Waiver and Amendment ("Fourth Amendment"), respectively,
the Transaction Documents were amended; capitalized terms used herein but not
otherwise defined herein shall have the meanings set forth in the Purchase
Agreement, the Note, the Warrant, the First Amendment, the Second Amendment, the
Third Amendment or the Fourth Amendment, as the case may be; and

          WHEREAS, the Company wishes to extend the Extended Waiver Period (as
defined below) without the anti-dilution adjustments applying as set forth in
the Transaction Documents in certain circumstances and to delay payments to
Holder for interest and Monthly Redemption Amounts due on and from October 1,
2009 through and including January 31, 2010 under the Note and subsequent
amendments until February 1, 2010.

          NOW THEREFORE, in consideration of the foregoing premises and the
mutual covenants set forth in this Amendment, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

     1.   Subsequent Issuance Waivers--Common Stock Issuances. --Common Stock
Issuances. Notwithstanding anything contained in the Transaction Documents,
including the First Amendment, Second Amendment, Third Amendment and Fourth
Amendment, to the extent the Company sells and issues shares of Common Stock or
warrants in one or more Common Stock Financings (as defined below) during the
period from December 18, 2008 until February 1, 2010 ("Extended Waiver Period")
for gross proceeds which do not exceed $800,000 in the aggregate, such issuances
shall constitute "Exempt Issuances" under the Transaction Documents, provided
that the Company hereby agrees that all issuances from Common Stock Financings
raising in excess of such $800,000 shall not constitute "Exempt Issuances" under
the Transaction Documents. For purposes hereof, "Common Stock Financing" means
the sale and issuance of shares of Common Stock by the Company in a capital
raising financing, provided that (a) the effective sale price per share of
Common Stock shall equal at least $0.05, (b) the transaction shall not be a
Variable Rate Transaction or MFN Transaction, and (c) the Company may issue to

                                       1
<PAGE>

the purchasers thereof, in connection with any such financing, warrants to
purchase a number of shares of Common Stock equal to 50% of the number of shares
of Common Stock sold to such purchasers in such financing, provided that the
effective exercise price per share of Common Stock under such warrants shall
equal at least $0.10. For clarification, a Common Stock Financing may result
from the sale and issuance of shares of Common Stock pursuant to the exercise of
currently outstanding warrants following a reduction of the exercise price
thereunder, provided that the provisions of the preceding sentence are
satisfied.

     2.   Monthly Redemptions. The Holder hereby agrees that the Company, at its
option, may delay payment of the interest and Monthly Redemption Amounts which
have not previously been paid or converted to Common Stock due on October 1,
2009 (including amounts which had been previously deferred until such date)
through January 31, 2010 until February 1, 2010 (in which case on February 1,
2010 the Company shall pay all interest and all the Monthly Redemption Amounts
due prior to such date and the payment due on February 1, 2010, i.e., a total of
$742,869.35, consisting of $628,399.84 principal and $114,469.51 interest
accruing under the Note from March 16, 2009 through February 1, 2010). The
Holder at its option may at any time and from time to time convert any or all of
said $742,869.35 in principal and interest under the Note into Common Stock of
the Company at a conversion price equal to $0.05 per share. The Company shall
give the Holder at least 5 days prior written notice of any early payment of any
portion of such amount, in which case such amount elected to be prepaid shall be
due and payable on such early payment date elected.

     3.   Temporary Conversion Cap. Until June 23, 2010, the maximum number of
shares into which the Note and Warrant are convertible and exercisable shall be
10,014,313 shares, provided that (1) such maximum number of shares may be
applied all to the Note or to the Warrant or a combination thereof as may be
determined by the Holder, and (2) any shares previously reserved for conversion
and exercise of the Note and Warrant by the Company shall remain reserved for
the Holder, and the Holder may use shares reserved for exercise of the Warrant
for conversion of the Note instead or as it may otherwise determine, in each
case in the sole discretion of the Holder. At all times on and after June 24,
2010, the Company shall cause there to exist, and reserve for issuance to the
Holder, a number of authorized and unissued shares of Common Stock at least
equal to 100% of the number of shares issuable to the Holder upon full
conversion and exercise of the Note and Warrant in accordance with the terms
thereof, without regard to any limitation contained therein on conversion,
exercise, beneficial ownership or the limitation contained in the preceding
sentence (which limitation shall terminate on June 23, 2010). If at any time on
or after June 24, 2010 the Company fails to have a sufficient number of shares
of Common Stock so reserved as required by the preceding sentence, then the
Holder shall have the right to compel the Company to redeem the portion of the
Note and/or Warrant held by the Holder which cannot be converted or exercised
due to such failure, as may be elected by the Holder. The redemption price for
any such portion of the Warrant redeemed under this subsection shall equal the
value of the Warrant being redeemed as determined using the Black-Scholes Option
Pricing Model via Bloomberg, and the redemption price under the Note shall be
the Mandatory Default Amount. Without limiting the foregoing, such failure shall
constitute an Event of Default under the Note.

     4.   Rule 144. The Company acknowledges and agrees that, for purposes of
Rule 144 promulgated under the Securities Act of 1933, as amended ("Securities
Act"), the holding period for the shares of Common Stock issuable upon

                                       2
<PAGE>

conversion or cashless exercise of, or otherwise pursuant to, the Note and/or
Warrant, shall have commenced on June 25, 2008 (the date of original issuance of
the Note and the Warrant), notwithstanding this Amendment. Without limiting the
foregoing, if at any time it is determined that such holding period does not
relate back to such date, the Company will promptly cause the registration of
all such underlying shares under the Securities Act (without regard to any
beneficial ownership or issuance limitations contained in the Note and/or
Warrant). In connection with any registration of shares of Common Stock pursuant
to this Section, the Company and the Holder shall enter into a registration
rights agreement containing customary and reasonable provisions regarding the
registration of securities under the Securities Act.

     5.   Disclosure. To the extent the transactions contemplated by this
Amendment constitute material non-public information concerning the Company or
are otherwise required to be publicly disclosed under the Securities Exchange
Act of 1934, as amended, and the rules promulgated thereunder, the Company
shall, within three (3) business days following the date hereof, issue a press
release and/or Current Report on Form 8-K disclosing the material terms of the
transactions contemplated hereby. The Company and the Holder shall consult with
each other in issuing any other press releases with respect to the transactions
contemplated hereby.

     6.   Miscellaneous.

            (a)   Full Force and Effect. Except as otherwise expressly provided
herein, each of the Purchase Agreement, the Note, the Warrant, the First
Amendment, the Second Amendment, the Third Amendment, the Fourth Amendment and
the other agreements and transactions contemplated thereby ("Transaction
Documents") shall remain in full force and effect. Except for the waiver and
modifications contained herein, this Amendment shall not in any way waive or
prejudice any of the rights or obligations of the Holder or the Company under
the Transaction Documents, under any law, in equity or otherwise, and such
modifications shall not constitute a waiver or modification of any other
provision of the Transaction Documents nor a waiver or modification of any
subsequent default or breach of any obligation of the Company or of any
subsequent right of the Holder.

            (b)   Governing Law. This Amendment shall be governed by and
construed in accordance with the internal laws of the State of New York.

            (c)   Counterparts. This Amendment may be executed in any number of
counterparts, each of which will be deemed an original, but all of which
together will constitute one and the same instrument. This Amendment may be
executed by facsimile or by email of a digital image format or portable document
format of the signature page hereto.
