5.1 Indemnity against any Third Party Claims. Subject to Article 13 hereof, each
Party ("Indemnifying  Party") will indemnify,  defend, and hold the other Party,
its  officers,   directors,  agents,  employees,  and  affiliates,   ("Indemnity
Parties")  harmless from and against any and all liabilities,  damages,  losses,
expenses,  claims,  demands,  suits,  fines or judgments,  including  reasonable
attorney fees, costs and expenses incidental thereto,  which may be suffered by,
accrued against,  charged to or recoverable from the Indemnity Parties,  arising
out of any third party claim. Promptly after receipt by the Indemnity Parties of
a threat of any action,  or a notice of the commencement or filing of any action
against which the Indemnity  Party may be indemnified  hereunder,  the Indemnity
Party shall give written notice thereof to Indemnifying  Party;  provided,  that
failure to give such  notice  shall not relieve  the  Indemnifying  Party of its
obligations  hereunder,  except  to  the  extent  such  failure  prejudices  the
Indemnifying Party's defense thereof. Indemnifying Party shall have sole control
of the  defense and of all  negotiations  for  settlement  of such  action.  The
Indemnifying  Party  shall be  permitted  to enter into a  settlement  hereunder
without the prior  written  consent of the  Indemnity  Party  provided  that the
settlement  does not result in any  attribution of fault or create any liability
or obligation on the part of the Indemnity  Party and the Indemnity  Party shall
not  enter  into  any  settlement  without  the  prior  written  consent  of the
Indemnifying Party. Nothing herein shall limit,  diminish or otherwise affect in
any way the indemnifications  made by the parties pursuant to the Asset Purchase
Agreement dated January 28, 2005 and all documents related thereto.


               6. Product & Product Materials Ordering Procedure,

                          Change Orders, & Cancellation

6.1  Agreement  to Sell.  Biowell,  within  the  limitations  contained  in this
Agreement,  shall sell to APDN or other  purchaser  licensed by  Licensor,  such
quantities of Licensed  Product and other Product  Materials as either may order
in accordance herewith.

6.2  Purchase  Orders.  For as long as  Biowell  remains  a source  of  Licensed
Products and Product Materials,  purchases thereof shall be initiated by written
or  electronically  dispatched  Purchase Orders  referencing  the quantity,  the
Licensed Product, applicable price, shipping instructions and requested Delivery
Dates.  All  Purchase  Orders for Products and other  Product  Materials  placed
hereunder shall be governed by the terms and conditions of this Agreement unless

                                       11

different terms and conditions of the Purchase Order are accepted by Biowell and
acknowledged  in writing.  Biowell will use  commercially  reasonble  efforts to
accept  each  Purchase  Order  issued  by APDN or other  purchaser  licensed  by
Licensor. Biowell will ship all Licensed Product or Product Materials within the
"Lead Time" agreed to by the parties prior to the  execution of this  Agreement,
unless the Purchase Order specifically states a delivery schedule different from
such Lead Time and such  delivery  schedule  is  accepted in writing by Biowell.
Biowell  shall  sell to APDN,  or other  purchaser  licensed  by  Licensor,  all
Licensed Products and Product Materials at a price equal to the lowest price and
on the best terms,  including  cash  discounts for early  payment,  or any other
discounts, credits or financial incentives then offered by it to any third party
with respect to the sale of a Licensed  Product or other  Product  Material.  If
Licensed  Products or Product  Materials  are sold to any third party at a price
that is less than the price then being  charged to APDN and/or  other  purchaser
licensed  by  Licensor,  then such party,  on a going  forward  basis,  shall be
entitled to (i)  purchase  any  Licensed  Products or Product  Materials at such
lower  price  until  such time as Biowell is no longer  offering  such  Licensed
Products or Product  Materials at such lower price and (ii) if APDN or any other
purchaser  licensed by APDN purchased any Licensed Products or Product Materials
during the period when  Biiowell was charging  such lower price,  Biowell  shall
promptly refund or credit to such party the difference  between the higher price
and the lower price.

6.3 Purchase Order  Information.  Purchase Orders shall, to the extent necessary
for Biowell to fulfill the terms thereof,  include:  (i) description of Licensed
Products and other Product Materials,  (ii) quantity of Licensed Products and/or
other  Product  Materials,  (iii) price per unit of Licensed  Products and other
Product  Materials (iv) total order price,  (v) Delivery Date, and (vi) delivery
location. Except as otherwise explicitly provided in this Agreement, any changes
to or  rescheduling  of an accepted  Purchase Order must be mutually  agreed and
incorporated  into a written  Change Order  referencing  the  original  Purchase
Order.

6.4 Confirmation.  Within seven (7) calendar days of its receipt of the Purchase
Order,  Biowell  will use its  commercially  reasonable  efforts to send written
notice    of    acceptance    or    rejection    of    the    Purchase     Order
("Confirmation/Rejection").

6.5 Delivery  Terms.  All Licensed  Products  delivered by Biowell  shall be FOB
(Taipei, Taiwan, ROC) or other place of shipment as specified in writing by APDN
or other  purchaser  licensed by Licensor and agreed to by Biowell.  Biowell may
ship partial orders provided  Biowell  notifies APDN or such other purchaser and
both agree prior to shipment.  The Purchase  Order shall  specify the carrier or
means  of  transportation  or  routing,   and  Biowell  will  comply  with  such

                                       12

instructions. If the order fails to provide shipping instructions, Biowell shall
select the best available carrier, on a commercially reasonable basis.

6.6 Change Orders and  Rescheduling.  Any modification to a Purchase Order shall
be made in writing by an authorized  representative  of APDN or other  purchaser
licensed by Licensor,  as the case may be ("Change Order"), and sent to Biowell,
and such Change Order shall be subject to  acceptance or rejection in writing by
Biowell  within seven (7) calendar days of its receipt  thereof and shall not be
binding until such  acceptance.  6.7 APDN agrees to  reciprocate  to Biowell all
terms and  conditions  set  forth in this  entire  Section  6 in the event  that
Biowell or its sub-licensee desires to purchase APDN Products.

                      7. Non-competition & Non-solicitation

7.1 During the term of this Agreement,  neither APDN, Licensor,  or any of their

intentionally  attempt to limit or  interfere  with any  business  agreement  or

                                       13

relationship  existing between either party and/or its affiliates with any third
party;  or (iii)  disparage  the business  reputation of the other party (or its
management  team) or (iv) take any actions that are harmful to the other party's
goodwill with its customers,  providers,  vendors,  employees,  the media or the
public,  or (v) sell any product that is competitive with the Licensed  Products
or the APDN Products or engage directly or indirectly in the conduct of business
with any company  considered by the parties  hereto to be  competitive  with the
business as set forth in this Agreement.

7.4 During the two (2) year  period  following  termination  of this  Agreement,
Biowell shall not, directly or indirectly (including without limitation, through
any  affiliate),  solicit any entity that shall have been a customer,  supplier,
consultant,  development or joint venture partner of APDN at any time within two
(2) years prior to  terminating  this Agreement to cease doing business in whole
or in part with  Licensor  or APDN,  as the case may be, nor may  Biowell or any
affiliate do business,  directly or indirectly,  with any such party during such
two (2) year period.

                               8. Confidentiality

8.1 Biowell  shall not use or divulge or  communicate  to any person (other than
those whose province it is to know the same or as permitted or  contemplated  by
this  Agreement  or with the  written  approval  of the other party or as may be
required by law):

     (i)  any Confidential Information; or

     (ii) any of the terms of this Agreement

8.2 Biowell shall prevent the unauthorized publication or disclosure of any such
Confidential  Information,  materials or  documents  and ensure that any person,
subject to the written approval of Licensor, to whom the information,  materials

by a similar  duty to maintain  confidentiality.  Biowell  shall ensure that its
directors, shareholders, employees, consultants, agents or advisors are aware of
and comply with the confidentiality and non-disclosure  provisions  contained in
this Section and shall  indemnify  Licensor and APDN as the case may be, against
any loss or damage  which  Licensor and APDN may sustain or incur as a result of
any  breach  of the  terms  hereof  by  Biowell,  its  directors,  shareholders,
employees, consultants, agents or advisors.


8.3 Licensor and APDN agree to  reciprocate  to Biowell all terms and conditions

(12) months after  delivery to the carrier for shipment (the  "Biowell  Warranty
Period").  During the Biowell Warranty Period, a party may notify Biowell if all
or any  portion  of such  Product  Materials  or  Licensed  Products  contains a

Product  Materials  and/or  Licensed  Products or, at Biowell 's discretion,  by
delivering  equivalent Product Materials and/or Licensed Products replacing such
defective  Product  Materials  and  Licensed  Products.  Biowell may inspect and
verify such alleged defect without need to ship the alleged  defective  items to
Taiwan.

     (ii) APDN  warrants  that all APDN Products sold by APDN under the terms of
this Agreement will be materially free from defects in workmanship and materials

Warranty  Period").  During the APDN Warranty Period, a party may notify APDN if
all or any  portion  of such  Product  Materials  or APDN  Products  contains  a
material  defect in materials  or  workmanship,  or  otherwise  fails to conform
substantially  to the  Specifications.  Provided  that such  notice is  received
during the APDN Warranty Period,  APDN shall promptly (but not later than thirty
(30) days after receiving such notice)  correct,  at its own expense (which will

defect without need to ship the alleged defective items to an APDN facility.

WARRANTY IF ITS TESTING AND EXAMINATION DISCLOSES THAT THE ALLEGED DEFECT IN THE
LICENSED PRODUCT, APDN PRODUCT OR PRODUCT MATERIAL DOES NOT EXIST (PROVIDED THAT
VERIFIABLE  PROOF OF SUCH TESTING AND  EXAMINATION IS PROVIDED) OR WAS CAUSED BY
MISUSE,  NEGLECT,  IMPROPER  STORAGE OR  INSTALLATION  OR TESTING,  UNAUTHORIZED
ATTEMPTS TO REPAIR, OR BY ACCIDENT, FIRE, LIGHTNING OR OTHER HAZARD.

13.6 Biowell will be liable for the Licensed  Product  manufactured  by Biowell.

coverage with respect to the Licensed  Products with minimum limits of liability
of One Million US Dollars (US$  1,000,000.00)  or otherwise agreed in writing by
both Parties.  Such  insurance  will name Licensor and APDN as additional  joint
insureds  thereon.  Biowell will, from time to time upon  reasonable  request by
APDN  and  Licensor,  promptly  furnish  or cause  to be  furnished  to APDN and
Licensor evidence in form and substance satisfactory to APDN and Licensor of the
maintenance of the insurance required by this Section, including certificates of
insurance and proof of premium payments.  APDN and Licensor's  customers are not
required to go to Biowell directly to file a claim of product liability. Biowell
will take all necessary  actions to defend APDN and Licensor with respect to any

respect to the Licensed Products with minimum limits of liability of One Million
US Dollars (US$  1,000,000.00)  or otherwise  agreed in writing by both Parties.

take all necessary actions to defend Biowell with respect to any such claim. All
expenses in this matter shall be paid by APDN or APDN's insurance.

13.9 EXCEPT FOR THE EXPRESSED WARRANTIES CREATED UNDER THIS AGREEMENT AND EXCEPT
AS SET FORTH  OTHERWISE  IN THIS  AGREEMENT,  IN NO EVENT SHALL  EITHER PARTY BE
LIABLE TO THE OTHER  FOR ANY  INCIDENTAL,  CONSEQUENTIAL,  SPECIAL  OR  PUNITIVE
DAMAGES  OF ANY KIND OR  NATURE  ARISING  OUT OF THIS  AGREEMENT  OR THE SALE OF
PRODUCTS,  WHETHER SUCH  LIABILITY  IS ASSERTED ON THE BASIS OF  CONTRACT,  TORT
(INCLUDING  THE  POSSIBILITY OF NEGLIGENCE OR STRICT  LIABILITY),  OR OTHERWISE,
EVEN IF THE PARTY HAS BEEN WARNED OF THE POSSIBILITY OF ANY SUCH LOSS OR DAMAGE,
AND  EVEN IF ANY OF THE  LIMITED  REMEDIES  IN  THIS  AGREEMENT  FAIL  OF  THEIR
ESSENTIAL PURPOSE.

13.10. In no event shall the aggregate liability of Biowell or APDN and Licensor
in connection with this Agreement,  or any other materials or services  provided
under this Agreement, whether arising in contract, tort or under any other legal
theory (including,  without limitation,  negligence or strict liability), exceed
the total value of the relevant Purchase Order.

13.11.  Biowell will be  responsible  for any warranty  claim  received from its
customers  and shall seek  appropriate  compensation  from APDN for any Products
manufactured  or delivered by APDN and its  associates  concerning  the Licensed
Products and Product Materials provided by APDN.

15.3 This Agreement may be executed in any number of counterparts, each of which
will be an original but all of which together will form one agreement.  Delivery
of an executed copy of this  Agreement by facsimile  transmission  will have the
same effect as delivery of an original signed counterpart.

15.4 The failure of either party  hereto to insist upon the strict  adherence to
any term of this  Agreement on any occasion  shall not be considered as a waiver
of any right  hereunder  nor shall it deprive  that party of the right to insist
upon the strict  adherence  to that term or any other term of this  Agreement at
some other time.

15.5 This  Agreement  constitutes  the  entire  agreement  between  the  parties
concerning  the subject  matter hereof and supersedes all written and oral prior
agreements and understandings with respect thereto.  No variation,  amendment or
modification  of the terms of this  Agreement nor any waiver of any of the terms
or  provisions  hereof  shall  be valid  unless  in  writing  and  signed  by an
authorized representative of each party.

15.6 If any  provision(s)  contained  herein  shall be  deemed  by any  court of
competent jurisdiction or arbitrator to be invalid, illegal or unenforceable for
any reason  (including,  but not limited to a violation of, or failure to comply
with, the then applicable provisions of the Fair Trade Act and/or the Principles
for Handling Cases Related to Technology Licensing Agreements), then the parties
hereto agree that said provision(s) shall be modified by the court or arbitrator
so as to be enforceable  to the maximum  extent  permitted by law (including the
Fair Trade Act and/or the  Principles  for Handling  Cases Related to Technology
Licensing  Agreements) and in such modified form shall be enforced in the manner
contemplated hereby.

15.7 Each of the  parties to this  Agreement  shall be  responsible  for its own
taxes and expenses  whether arising from or in connection with the execution and
delivery of this Agreement or otherwise.

15.8 Each of the parties hereby acknowledge and agree that money damages may not
be an  adequate  remedy  for  any  breach  or  threatened  breach  of any of the
provisions of this  Agreement and that, in such event,  they may, in addition to

                                       22

any other  rights and remedies  existing in their  favor,  apply to any court of
competent jurisdiction for specific performance,  injunctive and/or other relief
in aid of arbitration to preserve and protect the rights of the parties  pending
action by the arbitration panel.

15.9 This Agreement and all of the  provisions  hereof shall be binding upon and
inure to the benefit of the parties hereto and their  respective  successors and
permitted assigns,  but neither this Agreement nor any of the rights,  interests
or obligations hereunder shall be assigned by Biowell, including by operation of
law,  without the prior written  consent of Licensor.  For purposes  hereof,  an
assignment shall be deemed to have occurred upon (i) any merger or consolidation
of Biowell,  which merger or consolidation  results in the holders of the issued
and  outstanding  voting  securities  of  Biowell   immediately  prior  to  such
transaction  beneficially  owning or  controlling  less than a  majority  of the
voting  securities of the continuing or surviving entity  immediately  following
such merger or  consolidation,  (ii) the sale,  transfer or other disposition of
all or substantially all of the assets of Biowell,  or (iii) the sale,  transfer
or  other  disposition  of more  than  fifty  percent  (50%) of the  issued  and
outstanding  equity or voting rights of Biowell.  Subject to the exercise of its
rights under Section  11.1(a),  any  assignment of this  Agreement or any of the
rights, interests or obligations hereunder in contravention of this Section 15.9
shall be null and void and shall not bind or be  recognized  by the  Licensor or
APDN.

15.10 Force Majeure. Except for payment of monies, neither party shall be liable
for failure to fulfill its  obligations  under this  Agreement  or any  purchase
order  issued  hereunder  or for  delays in  delivery  due to causes  beyond its
reasonable  control,  including,  but not limited  to, acts of God,  man-made or
natural disasters, earthquakes, fire, riots, flood, material shortages, strikes,
delays in  transportation  or inability to obtain labor or materials through its
regular sources, lockouts, civil commotions, and other unforeseeable supervening
events;  provided  that the  party  claiming  any such  cause as an  excuse  for
non-performance  must provide  written  notice thereof to the other party within
fifteen (15) days of the  happening of the event that is the basis for the delay
or failure to perform.  The time for performance of any such obligation shall be
extended for the time period lost by reason of the delay.

15.11 The  provisions  of this Section and Sections  3.5, 3.6, 4.2, 5.1, 7.4, 8,
12, 13, 14 and 15.1 will survive the termination of this Agreement

                                       23


IN WITNESS  WHEREOF,  the parties  hereto have  executed  this  Agreement in two
