                             MODIFICATION AGREEMENT

     THIS MODIFICATION  AGREEMENT,  dated as of January 11, 2007, is made by and
between In Veritas  Medical  Diagnostics,  Inc.,  a  Colorado  corporation  (the
"Company"), and Longview Fund L.P. ("Longview").

     WHEREAS,  on  September 7, 2005,  the Company and  Longview  entered into a
Securities  Purchase Agreement  ("Securities  Purchase  Agreement")  pursuant to
which the Company issued to Longview a secured  convertible  debenture which has
an outstanding  principal amount,  plus accrued interest,  of $261,300 (the "Old
Debenture");   In  connection  with  the  Securities   Purchase   Agreement  and
contemporaneously  therewith,  the  Company  and  Longview  also  entered  in an
Investor Registration Rights Agreement (the "Registration Rights Agreement"), an
Intercreditor  Agreement  (the  "Intercreditor   Agreement"),   and  a  Security
Agreement  (the  "Security  Agreement").   The  Securities  Purchase  Agreement,
Registration Rights Agreement, Security Agreement,  Intercreditor Agreement, and
Debenture (as defined below) and all other  agreements  entered into between the
Company and Longview in connection therewith are collectively referred to herein
as the "Transaction Documents".

     WHEREAS,  the Company  acknowledges  that an event of default has  occurred
under the  Debenture  as a result of (i) the  Registration  Statement  not being
declared effective within 120 days after filing thereof,  and (ii) the Company's
breach of its  obligations  to make payments of principal and interest under the
Debenture (collectively, the "Existing Defaults").

     WHEREAS,  liquidated  damages in an amount of $48,000 have accrued pursuant
to the Registration Rights Agreement (the "Liquidated Damages").

     WHEREAS,  the  Company  and  Longview  wish to  provide  for the  terms and
conditions  pursuant to which (i) the Old  Debenture  shall be modified to a new
principal  amount of $261,300  which is  convertible  into  common  stock of the
Company at a  conversion  price of $0.05 per share (the  "Modified  Debenture"),
(ii) the Company shall pay to Longview lump sum payments in an aggregate  amount
of $25,000,  which shall be applied against the principal amount of the Modified
Debenture,  and (iii) the Company shall issue to Longview,  in  consideration of
the Liquidated  Damages, a debenture in a principal amount of $48,000,  which is
convertible  into common stock of the Company at a conversion price of $0.05 per
share (the "Second Debenture");

     NOW,  THEREFORE,  for good and  valuable  consideration,  the  receipt  and
sufficiency  of which the  parties  hereby  acknowledge,  the  parties  agree as
follows:


     1. Lump Sum  Payments.  The  Company  shall pay  Longview an  aggregate  of
$25,000.00  towards the Modified  Debenture in two  installments  of $12,500.00,
with the first payment being due and payable no later than February 28, 2007 and
the  second  payment  being  due and  payable  on March 30,  2007  (the  "Second
Payment").

     2.  Exchange  of Old  Debenture  for  Modified  Debenture.  The Company and
Longview  hereby agree that the Old Debenture  shall be exchanged for a Modified
Debenture in an outstanding  principal amount of $261,300,  which is convertible
into  common  stock at a  conversion  price of $0.05  per  share.  The  Modified
Debenture and Second Debenture shall be issued simultaneously with the execution
of this  agreement.  The Modified  Debenture  and Second  Debenture are attached
hereto as Exhibits A and B, respectively.

     3. Closing. Upon receipt of the Modified Debenture,  Longview shall deliver
the Old Debenture to the Company.

     4.  Company  Representations  and  Warranties  and  Covenants.  The Company
represents warrants and covenants to Longview as follows:

     a.  Organization.  The Company is a  corporation  duly  organized,  validly

of which are validly issued and outstanding.

     c. Authority; Enforceability. The Company has the requisite corporate power
and  authority  to  execute  and  deliver  this  Agreement  and to carry out its
obligations hereunder. The execution, delivery and performance of this Agreement
and the  consummation  of the  transactions  contemplated  hereby have been duly
authorized by all necessary  corporate  action on the part of the Company and no
other  corporate  proceedings  on the  part  of the  Company  are  necessary  to
authorize this Agreement or to consummate the transactions so contemplated. This
Agreement has been duly executed and delivered by the Company and  constitutes a
valid and binding obligation of the Company,  enforceable against the Company in
accordance  with its  terms,  except as (a)  enforceability  may be  limited  by
applicable bankruptcy,  insolvency,  fraudulent transfer,  moratorium or similar
laws from time to time in effect affecting  creditors'  rights generally and (b)
the availability of equitable remedies may be limited by equitable principles of
general applicability.

     d. Third Party Consents. No consent,  authorization,  order or approval of,
or filing or registration  with, any  governmental  authority or other person is
required for the execution and delivery of this Agreement or the consummation by
the Company of any of the transactions contemplated hereby.


     e. Common  Stock.  All shares of the  Company's  Common  Stock to be issued
pursuant  to this  Agreement  will  be,  when  issued,  free  from  liens,  duly
authorized, validly issued, fully paid and non-assessable.

     f. Most Favored Nation Exchange.  From the date hereof until the date three
(3) years after the date hereof, if the Company consummates an equity financing,
including an equity-linked  financing such as, but not limited to, a convertible
notes  financing  or a unit  financing  of notes plus  warrants  (a  "Subsequent
Financing"),  Longview shall have the right to exchange the principal  amount of
the Modified  Debenture and Second Debenture for any of the securities issued in
the Subsequent  Financing at the Subsequent  Financing price. If at any time the
Modified Debenture or Second Debenture is outstanding,  the Company shall offer,
issue or agree to issue  any  common  stock or  securities  convertible  into or
exercisable for shares of common stock (or modify any of the foregoing which may
be  outstanding)  to any person or entity at a price per share or  conversion or
exercise  price  per share  which  shall be less  than the  Conversion  Price in
respect of the Modified  Debenture and Second Debenture,  without the consent of
Longview, then the Conversion Price shall automatically be reduced to such other
lower price.

     g. Tacking.  The Company represents that the holding period of the Modified
Debenture  for Rule 144  purposes  tacks  with the  holding  period  for the Old
Debenture.  Upon  receipt of a valid  notice of  conversion,  the Company  shall
instruct  its legal  counsel  to  render an  appropriate  legal  opinion  to the
Company's transfer agent.
