Re:  Master  License  Agreement  dated as of  September  16, 2003 by and between
University of Maryland,  Baltimore  ("UMB") and Oncologix  Tech, Inc. (f/k/a JDA
Medical Technologies, Inc.) ("Oncologix"), as amended (the "MLA")

Dear Judy:

     This letter will confirm our agreement that the September 16, 2008 deadline
for  satisfaction  of the milestone set forth in Section 4.01(e) of the MLA will
be extended  until January 5, 2009.  However,  the extension is contingent  upon
satisfaction of each of the following to UMB's reasonable satisfaction:

     1.   On or before  November 30, 2008,  UMB shall have received a Research &
          Development Plan and Business Plan from IUT for  commercialization  of
          the  Patent  Rights  licensed  under  the  MLA,  which  plans  must be
          reasonably satisfactory to B.

     2.   On or  before  January  5,  2009,  Oncologix  shall  have  closed  the
          transactions  pursuant  to the Asset  Purchase  Agreement  dated as of
          August 18, 2008 between Oncologix and Institut fur  Umwelttechnologien
          GmbH ("IUT").

     3.   On or before January 5, 2009, UMB shall have entered into a new Master
          License  Agreement with IUT (or a subsidiary to be formed as described
          in the Asset Purchase Agreement,  i.e. IUT Medical Gmbh), on terms and
          conditions reasonably satisfactory to UMB.

     4.   On or before January 5, 2009,  Oncologix  shall have taken the actions
          described in the Proxy  Statement  filed with the U.S.  Securities and
          Exchange Commission on September 8, 2006.

     5.   Between  the date of this  letter and  January 5, 2009,  the MLA shall
          have remained in full force and effect without default by Oncologix.

     If  any of the  above  conditions  is not  satisfied  to  UMB's  reasonable
satisfaction: UMB's agreement to extend the milestone deadline shall be null and
void;  Oncologix  shall be in  default of the MLA for  failure  to  achieve  the
milestone by the  original  deadline of  September  16,  2008;  and UMB shall be
entitled to any and all remedies for that breach as are set forth in the MLA.

     In consideration  of the granting of this extension,  Oncologix shall issue
to UMB two million  (2,000,000)  additional  shares of Oncologix  common  stock.
Those shares shall have all of the rights of all other shares of common stock of
Oncologix  currently  owned by UMB.  Such shares shall be issued to UMB no later
than September 30, 2008.

     UMB  understands  and  acknowledges  that those shares will be  "restricted
securities"  under  federal and state  securities  laws insofar as they have not
been  registered  under the Securities Act of 1933, as amended ("1933 Act"),  or
the securities  laws of any other  jurisdiction,  that they may not be resold or
transferred without compliance with the registration or qualification provisions
of the 1933 Act or applicable  federal and state securities laws of any state or
other  jurisdiction  or an  opinion  of  counsel  that an  exemption  from  such
registration and qualification  requirements is available.

     If you agree with the  foregoing,  please  indicate  your  agreement to the
foregoing by signing below and returning a signed copy to me.




                                            Sincerely,
