     substantially  equivalent  in cost,  operation and  performance  to the OEM
     Product  during the term of this  Agreement  to any third  party at a price
     which is then less than what MDT is paying to TGC (based on like  volumes),
     then TGC shall adjust MDT's  purchase  price for the OEM Product to a level
     equal to the  third  party's  pricing  level  based on like  volumes,  such
     adjustment  to be  retroactive  to the first  day TGC  offered  such  lower

forth in Exhibit B do not include any sales,  excise,  use, value added or other
government  taxes or duties  that may be  applicable  to the  export,  import or
purchase of the OEM Product, which taxes shall be the sole responsibility of MDT
and MDT  agrees  that it will bear all such taxes and  duties.  When TGC has the
legal  obligation to collect  and/or pay such taxes or duties,  the  appropriate
amount  shall  be  added to MDT's  invoice  and paid by MDT to TGC,  unless  MDT
provides  TGC  with  a  valid  tax  exemption  certificate   authorized  by  the
appropriate governmental taxing authority, or provides proof of payment.

     5.3  Order.  All orders for OEM  Product  and parts  shall be by means of a
signed written purchase order,  which shall be submitted to TGC at TGC's address
for notice  purposes  set forth in Section  13.1,  and shall  request a delivery
date.  Orders may be placed by telephone,  facsimile  transmission  or, upon the
parties' agreement,  on TGC's Web-Site or by e-mail;  provided,  however, that a
signed confirming purchase order is received by TGC ten (10) business days after
such order.  It is understood  that MDT and TGC may use their standard  purchase
order and sales agreement  forms during the  performance of this Agreement.  Any
purchase  order,  sales  agreement or other form used by MDT or TGC shall be for
convenience  only and any terms or  provisions  contained  therein  which are in
addition to or inconsistent  with those contained herein shall have and be of no
force and effect;  provided,  however, that the terms on such documents shall be
effective to the extent they set forth quantities, scheduled delivery dates and,
as applicable, mode of shipment.

shipment of the OEM Product ordered by MDT.  Except as otherwise  specified in a
purchase order, payment terms will be net thirty (30) after the date of invoice.

actual shipping address for the OEM Product. Each such invoice shall state MDT's
aggregate and unit purchase price for OEM Product in the relevant shipment, plus
any freight, taxes or other costs incident to the purchase or shipment initially
paid by TGC and to be borne by MDT hereunder. MDT shall make all payments to TGC

written  consent.  Any disputes shall be resolved in good faith.  To that end, a
senior  representative  appointed  by each  party  shall meet and confer in good
faith to amicably  resolve the alleged  dispute  over the  invoice.  If they are
unable to agree to a resolution after thirty (30) business days, the parties may

Product,  TGC shall, at its sole option,  cost and expense (a) promptly  replace
any recalled OEM Product with new compliant OEM Product;  or (b) promptly  issue
credit to MDT for any  recalled  OEM Product  unless such Recall was caused by a
modification of the OEM Product by MDT. TGC shall pay, or reimburse MDT, for all
reasonable  out-of-pocket  expenses  incurred  in  effecting  such Recall of OEM
Products,  including  without  limitation,  any shipping costs related to return
and/or  replacement  of recalled OEM Products  unless the Recall was caused by a
modification  of the OEM Product by MDT.  For the purpose of this  Section  6.4,
"Recall" means any required  removal of OEM Product from the inventory of MDT or
MDT's customers as required by any law,  regulation,  or order of a governmental
authority,  or at the reasonable  discretion of either party after determination

unsuitable for clinical use.

     6.5 Records.  Each party shall  maintain for at least five (5) years or the
applicable  regulatory  requirement,  which  ever is  longer,  their  respective
records to ensure compliance with any regulatory requirements, including but not
limited to traceability of all shipments of the OEM Product. These records shall
include  the part  number  (if any),  manufacturing  dates,  shipping  dates and
lot/batch  number.  Each  party  shall be  allowed  access to the other  party's
records at all reasonable  times during normal  business hours, or at such other
times that are  mutually  agreeable  to the parties,  following  the  requesting
party's  request.  At the  request and  direction  of any  governing  regulatory
authority, each party shall allow such authority access to its records.

     6.6 Notice of  Proceedings.  Each  party  shall  notify the other  party in
writing  within  five (5)  business  days of the  commencement  or threat of any
action,  suit,  proceeding or investigation or the issuance of any order,  writ,
injunction,  award,  judgment  or  decree  before  or of  any  court,  tribunal,
arbitration panel,  agency or governmental  instrumentality  that may materially
and  adversely  affect  the other  party's  rights  or  obligations  under  this
Agreement.

     6.7  Litigation.  If  either  party  becomes  involved  in  any  litigation
regarding the OEM Product within the Territory (each, a "Litigating Party"), the
other party agrees to provide all relevant documents or information  (except for
privileged communications or information or Confidential Information which shall
be  governed  by  Section  10) to the  Litigating  Party  and  to  provide  such
cooperation with the Litigating Party in the conduct of such litigation,  all as
may be reasonably requested by the Litigating Party. Each party shall notify the
other party in writing within ten (10) business days of the  commencement of any
action,  suit,  proceeding or investigation or the issuance of any order,  writ,
injunction,  award,  judgment  or  decree  before  or of  any  court,  tribunal,
arbitration panel, agency or governmental instrumentality that relate to the OEM
Product.

     7.1 Initial Term. The initial term of this Agreement  shall commence on the
Effective Date of this Agreement and shall continue in full force and effect for

forth below.

                                       8


          (a) If either  party  hereto is in  breach of any  material  terms and
     conditions of this Agreement and such party fails to cure the breach within
     thirty (30) days after the date of receipt of written notice from the other
     party advising of the nature of such breach,  then the party not in default
     shall have the right to terminate  this  Agreement by written notice to the
     party in breach.

          (b) If either  party:  (i)  becomes  insolvent;  (ii)  makes a general
     assignment  for the  benefit  of its  creditors;  (iii)  files or has filed
     against it a petition in bankruptcy or seeks  re-organization  which is not
     dismissed  within 60 days;  (iv) has a receiver  appointed  over any of its
     assets;  or (v) institutes any  proceedings  for liquidation or winding up;
     then the other party may, in addition to other  rights and  remedies it may
     have, terminate this Agreement immediately by written notice. If TGC is the
     party to which any of the foregoing  apply,  TGC shall use its best efforts
     to  ensure  that  the  rights  of  MDT  hereunder  continue  unaltered  and
     uninterrupted.

          (c) Either party may terminate  this  Agreement if the other party has
     failed to perform  its  obligations  due to an event of Force  Majeure  (as
     defined  at  Section  13.12)  for a period  of  thirty  (30)  days or more;
     provided, however, either party may terminate this Agreement immediately if
     such Force Majeure is  attributable  to any new or changing  regulations or
     laws  of any  government  or  interpretation  thereof  by any  judicial  or
     regulatory authority that materially impair such party's ability to perform
     or meet its obligations under this Agreement.

          (d) MDT may  terminate  this  Agreement  by  giving  thirty  (30) days
     written  notice of termination to TGC in the event that TGC fails to timely
     fill MDT's purchase orders for the OEM Product.

          (e) MDT may terminate  this Agreement  without cause,  upon 30 days of
     written notice.  If this Agreement is terminated by MDT without cause under
     this  section,  MDT shall be reimburse TGC for (i) all work in progress and
     associated   labor   for   the   OEM   Product,    and   (ii)   all   other
     non-cancelable/non-returnable   raw  materials  and  components  reasonably
     purchased by TGC for the sole purpose of manufacturing the OEM Product. The
     provisions in this  paragraph  will be TGC's sole and exclusive  remedy for
     any  termination  of this Agreement by MDT under this section  7.2(e).  TGC
     will take all reasonable measures to return unused material and cancel open
     supplier purchase orders in event of termination.

          (f) TGC may  terminate  this  Agreement  by  giving  thirty  (30) days
     written  notice of termination to MDT in the event that MDT fails to timely
     pay TGC's invoices for OEM Product that has been accepted by MDT unless MDT
     cures the payment default within thirty (30) days of receipt of the written
     notice from TGC.  For purposes of this  Section,  accepted OEM Product does
     not include disputed invoice amounts, as provided for in Section 5.5 above.

          (c) The  obligations  and  duty of MDT to pay in full  all  undisputed
     amounts due to TGC for OEM  Product  which has been  accepted  by MDT.  For

                                       9

     above.

     7.4  Effects  of  Termination.  Upon  expiration  or  termination  of  this
Agreement:

          (a) All rights granted under this Agreement  shall terminate as of the
     Termination  Date and MDT shall cease to utilize any rights  granted  under
     this Agreement; provided, however, that MDT shall be entitled to (i) cancel
     any outstanding  purchase orders to TGC for the OEM Product;  (ii) continue
     to use,  promote,  distribute and sell any of the OEM Product to the extent
     necessary  to fill  any  customer  orders  that are  outstanding  as of the
     Termination Date; (iii) continue to use,  promote,  distribute and sell the
     OEM Product on a nonexclusive  basis until its inventory of the OEM Product
     is exhausted;  and/or (iv) at the election of TGC,  allow TGC to repurchase
     any such existing  inventory of OEM Product from MDT at the original  price
     paid by MDT therefore.

     certification of such destruction.

     7.5  Continuation  of Business.  If TGC intends to cease  production of the
Thrombin Processing Device for any reason, it will give MDT notice in writing at
least  ninety (90) days before  cessation  of  production  and will give MDT the
opportunity for a last time buy of the OEM Product in quantities consistent with
previous annual purchases by MDT.

be sent  directly to TGC.  The RA number shall be  prominently  displayed on the
outside of the  shipping  box and the OEM  Product  shall be packaged to protect
them from shipping  damage.  TGC shall bear shipping costs  associated  with all

     party grants any right,  title or interest the other  party's  Intellectual
     Property.

          (b) The parties herein waive any right to claim that,  pursuant to the

          10.1 Confidential Information.

               (a) In performing the obligations  under this Agreement,  MDT and
          TGC may come into  contact  with,  be given  access to,  and,  in some
          instances,  contribute to each other's  Confidential  Information.  In
          consideration of permitting MDT and TGC to have access to each other's

                                       10


          Confidential Information, during the term of this Agreement and at all
          times thereafter,  MDT and TGC agree that, subject to the requirements
          of Section 1.2,  above,  during the term of this Agreement and for two
          (2) years after its termination or expiration, they shall not disclose
          to any third  party any  Confidential  Information  of the other party
          without the other  party's  prior  written  consent,  except as may be
          required  to  meet  regulatory  obligations  related  to  the  parties
          products. MDT and TGC shall only make the Confidential  Information of
          the other party available to its employees on a need-to-know basis and
          agree to take  appropriate  action by  instruction  or agreement  with
          their respective  employees for a permitted access to the Confidential
          Information to satisfy the obligations under this Article 10.1.

               (b) In the event the receiving party or its  representatives  are
          requested   or   become   legally   compelled   (by  oral   questions,
          interrogatories,  requests for information or document subpoena, civil
          investigative  demand or similar process) to disclose any Confidential
          Information  furnished by the disclosing  party,  the receiving  party
          agrees that it will provide the  disclosing  party with prompt written
          notice  of such  request(s)  so that the  disclosing  party may seek a
          protective order or other  appropriate  remedy and/or waive compliance
          with the provisions of this Agreement.

               (c) The receiving party will promptly notify the disclosing party
          of any  unauthorized  disclosure or use, and will  cooperate  with the
          disclosing party to protect all of its intellectual property rights in

the Securities  Exchange Act of 1934, as amended,  and use its  reasonable  best
efforts to seek, confidential treatment of certain information contained in this
Agreement.

     10.3 Previous  Confidentiality  Agreements.  The Parties  acknowledge  that
these   confidentiality   provisions   supersede  any  previous   agreements  of
confidentiality  between the Parties,  which previous agreements are hereby null
and void.

     10.4  Retention  of  Confidential  Information.  Upon  termination  of this
Agreement,  a receiving party may retain, in the possession of its legal counsel
for  evidentiary  purposes,  one  copy of any  Confidential  Information  it has
received.

          (d) TGC has not granted,  and during the term of this Agreement  shall

     TGC shall otherwise  maintain a quality level of each OEM Product necessary
     to obtain and retain approval by the FDA and any other governing regulatory
     authorities.

          (h) TGC  warrants  that  for a  period  commencing  with  the  date of
     shipment of any OEM Product to MDT and continuing  until the earlier of (i)
     18 months from the date of shipment to MDT or (ii) 1 year after sale by MDT
     to its customer (the "Warranty Period"),  the OEM Product shall satisfy the
     specifications  mutually agreed by the parties, be free of defects,  and be
     manufactured  pursuant  to  all  applicable  standards  prescribed  by  all
     governing regulatory authorities;  provided however, that damage to any OEM
     Product by MDT or its  customers  through  misuse,  neglect,  accident,  or
     failure to follow the printed procedures and recommendations of instruction
     for use or storage of the OEM  Product  shall  void this  warranty.  In the

     Section 11.2(h) shall pass through to MDT's customers.

          (i) The execution,  delivery and  performance by TGC of this Agreement
     and the consummation of the transactions contemplated hereby do not violate
     or conflict with the  Certificate  of  Incorporation  or Bylaws of TGC, any
     material  contract,  agreement or  instrument to which TGC is a party or by
     which it or its properties  are bound,  or any judgment,  decree,  order or
     award of any court,  governmental body or arbitrator by which TGC is bound,
     or any law, rule or regulation applicable to TGC.

          (j) Patent,  Copyright and Proprietary Rights Indemnity. TGC shall, at
     its expense, defend and indemnify MDT and its officers,  directors,  agents
     and  employees  harmless  for damages and  reasonable  expenses  (including

     promptly notified,  rendered reasonable assistance by MDT as required,  and
     permitted to direct the defense or settlement  negotiations.  The foregoing
     obligation  of TGC  does not  apply  with  respect  to the OEM  Product  or
     portions or  components  thereof  which is or was:  (i) made in whole or in
     part in accordance with MDT's  specifications  or instructions and such MDT

     thereof or after  receiving a modification  delivered at TGC's expense that
     would have avoided the alleged infringement, or (iv) where MDT's use of the
     OEM Product is not in accordance with this Agreement.

     11.2 MDT Representations and Warranties. MDT represents and warrants that:

          (a) MDT has the power to enter  into this  Agreement  and  perform  in
     accordance   with  the  provisions   hereof  and  that  the  execution  and
     performance  of the  Agreement  has been  duly and  validly  authorized  in

Agreement, and (b) the market will fail to accept such OEM Products. TGC and MDT
acknowledge  that MDT and its Affiliates are and shall continue to be engaged in

all of its  rights or  delegate  any or all of its duties  under this  Agreement
without the prior written consent of the other party, which consent shall not be

merger or acquisition or by purchase of all or  substantially  all of the assets
of the party related to the business which is the subject of this Agreement,  if
such  successor  agrees  in  writing  to be bound by the  terms  and  conditions

to the benefit of their respective successors and permitted assignees.

     13.3  Survival.  Sections  6.5,  7, 9, 10, 11, 12 and 13 shall  survive the

     13.4 Entire Agreement, Amendment and Modification. This Agreement expresses
the entire  understanding  of the parties  hereto and replaces any prior oral or
written  agreements  concerning  the  subject  matter  hereof,  and  each  party
acknowledges  that it has not  executed  this  Agreement  in  reliance  upon any
promise,  agreement,  representation or warranty not expressly set forth in this
Agreement.  No amendment or supplementation hereof shall be effective or binding
on either  party  hereto  unless  reduced to writing  and  executed  by the duly
authorized representatives of both parties hereto.  Notwithstanding the terms of

                                       15


either this  Agreement  or the  Agreement  for Mutual  Exchange of  Confidential
Information  between  MDT and TGC,  dated  September  16,  2004 (the  "September
Confidentiality  Agreement"),  the  September  Confidentiality  Agreement  shall
continue  in force and  effect,  in  accordance  with its  terms,  but only with
respect to the information  disclosed by the parties pursuant to that agreement.
Exhibit C lists the information  marked as confidential  and disclosed to MDT by
TGC under the September Confidentiality Agreement.

     13.5 Taxes.

          a) MDT shall be responsible  for all taxes on income or gross receipts
     of MDT levied by  governmental  authorities  within the  Territory  and for
     collection,   remittance  and  payment  of  any  and  all  taxes,  charges,
     withholding  obligations,  levies,  assessments  or other  fees of any kind
     imposed by any governmental  authority within the Territory with respect to
     MDT's operations.

          b) TGC shall be responsible  for all taxes on income or gross receipts
     of TGC levied by  governmental  authorities  within the  Territory  and for
     collection,   remittance  and  payment  of  any  and  all  taxes,  charges,
     withholding  obligations,  levies,  assessments  or other  fees of any kind
     imposed by any governmental  authority within the Territory with respect to
     TGC's operations.

          c) In the event  that MDT or TGC shall  become  subject  to any tax or
     other levy imposed by any  governmental  authority of the United  States or
     any other jurisdiction  within the Territory by virtue of this Agreement or
     in  connection  with  the  exercise  of  rights  granted  hereunder  or the
     performance of obligations  imposed  hereunder by either party and such tax
     or other levy is not otherwise dealt with under this Agreement, MDT and TGC
     agree to meet in good faith to determine the  allocation of  responsibility
     for such tax or other levy.

     13.6 Governing Law.

          a) This Agreement  shall be construed and governed in accordance  with
     the internal laws of the State of California  without regard to conflict of
     law  principles.  The parties agree that the United  Nations  Convention on
     Contracts  for the  International  Sale of Goods  shall  not  apply to this
     Agreement.  In the event any legal action  becomes  necessary to enforce or
     interpret the terms of this  Agreement,  the parties agree that such action
     will be brought in the state or federal  courts  located in San  Francisco,
     California and the parties hereby submit to the exclusive  jurisdiction  of
     said courts.

          b)  Notwithstanding   Section  13.6(a),   in  order  to  expedite  the
     resolution of legal disputes,  the parties shall have any disputes  arising
     in  connection  with  this  Agreement  finally  settled  under the Rules of
     Conciliation  and Arbitration of the  International  Chamber of Commerce by
     one or more  arbitrators  appointed in  accordance  with such rules,  whose
     decision shall be binding upon the parties;  provided,  however, that in no
     event shall any dispute regarding ownership of either party's  Intellectual
     Property  Rights be subject to arbitration  unless  mutually agreed upon by
     both parties.  Any arbitration  shall be conducted in the English  language
     with the place of arbitration  to be in San  Francisco,  California or such
     other  location  as  may be  mutually  agreed  upon  by  the  parties.  The
     arbitrator(s)  shall  be  entitled  to  award  costs  and  will be bound by
     limitations on liability or remedies set forth in this Agreement.

          c) The  parties  consent  to any  order or award or  decision  made in
     accordance with Sections 13.6(b),  being made an order of court anywhere in
     the  Territory.  Furthermore,  in the event either party  believes that any
     matter is so  urgent  that  application  to a court  for  urgent  relief is
     essential,  such  party may  approach  any court with  jurisdiction  in the
     Territory for urgent relief and for any subsequent related relief.

                                       16


     13.7 Relationship Of The Parties. Both parties are independent  contractors
of the other  under this  Agreement.  Neither  party  shall have the  authority,
either express or implied, to make any commitment or representation on behalf of
the other party or incur any debt or  obligation  on behalf of the other  party;
provided,  however,  that MDT shall,  if  necessary,  be deemed an agent for the
limited  purpose  of  prosecuting  a  Third  Party  Infringement.   The  parties
acknowledge  that this Agreement  does not  constitute a franchise  under United
States federal or state law or under any law of the Territory or any sovereignty
within the  Territory and does not create a fiduciary  relationship  between the
parties.

     13.8 Severability. If any provision of this Agreement is found by any court
of competent  jurisdiction to be invalid or unenforceable,  such provision shall
be deemed to be modified to the minimum extent necessary to cause it to be valid
and enforceable and the invalidity or  unenforceability  of such provision prior
to such modification shall not affect the other provisions of this Agreement and
all provisions not affected by the invalidity or  unenforceability  shall remain
in full force and effect.

     13.9  Remedies Not  Exclusive.  No remedy  conferred by any of the specific
provisions  of this  Agreement is intended to be exclusive of any other  remedy,
except as expressly provided in this Agreement or any Exhibit thereto,  and each
and every  remedy  shall be  cumulative  and shall be in addition to every other
remedy given  hereunder  or now or hereafter  existing in law or in equity or by
statute  or  otherwise.  The  election  of any one or more  remedies  shall  not
constitute a waiver of the right to pursue other available remedies.

     13.10  Waiver.  Failure  of  either  party  at  any  time  to  require  the
performance of any provision  under this Agreement shall not affect the right of
such party to require full  performance  thereafter and a waiver by either party
of a breach of any provision of this Agreement  shall not be taken or held to be
a waiver of any further or similar breach or as nullifying the  effectiveness of
such provision.

     13.11 Attorneys'  Fees. In any action on or concerning this Agreement,  the
prevailing  party will be awarded  its  reasonable  attorneys'  fees,  costs and
necessary disbursements, to be paid by the non-prevailing party.

     13.12 Force  Majeure.  If performance  hereunder is interfered  with by any
condition  beyond  a  party's  reasonable  control  and  without  its  fault  or
negligence (a "Force  Majeure"),  the affected  party shall be excused from such
performance to the extent of such Force Majeure and shall have no responsibility
or  liability  for such  failure to  perform.  The party  whose  performance  is
prevented by a Force Majeure event shall  immediately  inform the other party of
the Force Majeure event and all reasonable information relating thereto.

     13.13  Counterparts.  This Agreement may be signed in counterparts  and all
signed copies of this  Agreement  will together  constitute one original of this
Agreement.
