     its customers to use, the Licensed Products, and Packard agrees, under the
     terms of such a license, to pay a royalty to such a Third Party, then the
     royalty rate payable to Dade Behring with regard to such Licensed Products
     shall be reduced by [* * *], up to a maximum [* * *] reduction for
     Packard's initial aggregate Net Sales Revenues of Licensed Products of

     Agreement shall be payable in United States currency by electronic funds
     transfer (SWIFT) to the account identified immediately below. The
     obligations to pay shall only be fulfilled on the day on which the relevant
     amount of money is credited to the aforesaid account. For the conversion of
     non-US currency into U.S. Dollars with respect to payments due, the
     average of the official spot selling rates published in the Wall Street
     Journal on the last business day of each of the months during the period to
     which the payment of royalties relates and including the Sixty (60) day
     reporting period thereafter shall apply. If any payment is delayed, the
     spot selling rate(s) valid on the last business day of the month(s) of the
     delay shall be added to the average calculation. Packard shall be
     responsible on its own account for any charges for conversion of currencies
     and the transfer of funds into the designated Dade Behring account. Dade
     Behring shall be responsible on its own account for its own corporate
     income taxes.

     Wall Street Journal on the last business day of the month(s) of the delay
     plus [* * *] percentage points, from the due date until paid, provided,
     however, that if this interest rate is held to be unenforceable for any
     reason, the interest rate shall be the maximum rate allowed by law at the
     time the payment is due. Any such losses suffered by Dade Behring in terms
     of less favorable exchange rates as a result of such delayed payments will
     be refunded by Packard to Dade Behring.

5.4  The Net Sales Revenues of the Licensed Products that are commercially used
     by Packard and which are conveyed by Packard to any person, firm or

     Revenues and of the royalties or other payments to Dade Behring required by
     way of any other provision under this Agreement. All books and the
     supporting data shall be open at all reasonable times, for three (3) years
     following the end of the calendar year to which they pertain (and access
     shall not be denied thereafter, if records are reasonably available), to
     the inspection of an independent certified public accountant retained by
     Dade Behring and reasonably acceptable to Packard for the purpose of
     verifying Packard's royalty statements and Packard's compliance in other
     respects with this Agreement. Dade Behring shall limit such inspections to
     once per calendar year. If in dispute, such records shall be kept until the
     dispute is settled. The inspection of records shall be at Dade Behring's
     sole cost and expense, unless the inspector concludes that royalties
     reported by Packard for the period being audited are understated by [***]
     or more from actual royalties and at least [***], in which case the costs
     and expenses of such inspection shall be paid by Packard. The information
     made available to the independent certified public accountant shall be in
     accordance with standard auditing practices.

     The independent certified public accountant may disclose the information
     specified in Section 5.5, but not the additional information identified in
     this Section, to Dade Behring. Notwithstanding the preceding sentence, in
     the event that royalties reported by Packard for the period being audited
     are, in the opinion of the independent certified public accountant,
     understated by [* * *] or more from actual royalties and at least [* * *],
     then Dade Behring shall have the right to obtain access to such additional
     information identified in this Section (except for identification of
     Packard's customers). Such access by Dade Behring shall be restricted to
     the person designated as the financial controller of Dade Behring, and Dade
     Behring's legal counsel. Subject to Article VIII, such

treatment and filed separately with the Securities and Exchange Commission
pursuant to Rule 24b-2 under the Securities Exchange Act of 1934,
as amended.


                                    Page 11


     controller and legal counsel shall ensure that such additional information
     is not disclosed in whole or part (verbally, by access to documents, or
     otherwise) to any other persons; and that such information is not used by
     Dade Behring for any purpose other than the collection of royalties and
     enforcement of this Agreement. All information disclosed to Dade Behring,
     and to the independent certified public accountant under this Section shall
     be protected under Article VIII. All information disclosed to the
     independent certified public accountant under this Section shall be kept
     confidential from Dade Behring, except as specifically provided in this
     Agreement.

5.7  In the event that any action is brought against Packard alleging that the
     manufacture, use or sale of any Licensed Products or Labels infringes the
     patent rights or any other rights of a Third Party and such allegation of
     infringement relates to any Dade Behring Technology, Packard's obligation
     to remit the royalties set forth in Section 5.2 to Dade Behring with
     respect to the allegedly infringing Licensed Products shall be suspended,
     provided that if such action terminates with no finding of infringement and
     no other adverse finding or adverse effect, then Packard's obligation to
     remit the royalty payments set forth in Section 5.2 shall be reinstated. No
     other royalty or other obligation, including royalties due under the
     Sublicense Agreement, shall be suspended in the event that any action is
     brought against Packard alleging that the manufacture, use or sale of
     Licensed Product or Labels infringes the patent rights or any other rights
     of a Third Party and such allegation of infringement relates to any Dade
     Behring Technology.

5.8  If, after the end of the third year from the Effective Date, and any
     subsequent year of this Agreement, Packard's aggregate running royalties,
     as computed in accordance with Section 5.1 hereof do not exceed [* * *],
     then on or prior to January 30 of the following year, Dade Behring
     has the option to terminate or convert the license granted hereunder to a
     royalty bearing (as set forth in Section 5.1) non-exclusive license and
     Section 5.2 hereof shall no longer be of any force and effect. Dade Behring
     may not invoke the option of this Section 5.8 if the failure of Packard to
     reach such aggregate running sales is attributable to the action or
     inaction of Dade Behring. Dade Behring may not invoke the option of this
     Section 5.8 if the failure of Packard to reach such aggregate running sales
     is attributable to the cessation of sales of Licensed Products due to a
     pending Third Party patent infringement suit against Packard based upon
     Packard's manufacture, use or sale of Licensed Products.

5.9  The aggregate amount of all payments made by Packard under the Sublicense
     Agreement shall be applied by Dade Behring as a credit against amounts owed
     by Packard under Section 5.1 of this Agreement.

     pursuant to this Agreement shall be owned exclusively Dade Behring.

6.2  All right, title and interest to any improvements to Original Technology or
     Supplemental Technology of Packard or its Affiliates, and any new

     Packard, and resulting from any collaboration or joint efforts pursuant to
     this Agreement shall be owned exclusively by Packard.

6.3  During the term of this Agreement, each party shall promptly notify the
     other in writing of any significant improvement or modification, invention
     or discovery, whether or not believed to be patentable conceived, reduced

     Technology, Supplemental Technology or Dade Behring Improvement of the
     other party. In addition, the notifying party shall promptly provide the
     other party with a detailed written description of any such invention or
     discovery. In the event that Dade Behring, in its sole discretion, elects
     not to file for patent or other intellectual property protection with
     regard to a LOCI related invention or discovery arising out of this
     Agreement by Dade Behring, and Dade Behring determines that it does not
     wish to maintain such invention or discovery as a trade secret, then Dade
     Behring shall notify Packard of such decision. Packard, may, in its
     discretion, file for intellectual property protection with regard to such
     invention or discovery; provided that Dade Behring and its Affiliates will
     have an irrevocable, royalty-free, world-wide, license, with the right to
     fully sublicense, to practice under such invention or discovery. In the
     event that Packard, in its sole discretion, elects not to file for patent
     or other intellectual property protection with regard to a LOCI related
     invention or discovery arising out of this Agreement by Packard, and
     Packard determines that it does not wish to maintain such invention or

     such invention or discovery.

6.4  Dade Behring and/or its Affiliates represent and warrant that it/they
     has/have legal title to, owns, or is the licensee of, the Dade Behring
     Original Technology, including the Dade Behring Patents, and has the right

     the Effective Date,


                                    Page 13


     (without any investigation) of Dade Behring's executive officers Dade
     Behring represents that no other party has made any written claim of
     ownership of or title to any of the Dade Behring Patents. Dade Behring has
     not previously granted any rights (and is not bound by any agreement to
     grant any rights) in the Dade Behring Original Technology, including the
     Dade Behring Patents, that conflict with the rights granted to Packard
     hereunder. Dade Behring represents and warrants that as of the Effective
     Date, Dade Behring is a licensee of [* * *]. In its sole discretion, Dade
     Behring shall take all actions as may be necessary to maintain the Dade
     Behring Patents, including the payment of any maintenance fees, and ensure
     that the Dade Behring Patents are in full force and effect throughout the
     term of this Agreement. In the event that Dade Behring decides to abandon
     a Dade Behring Patent or not make a maintenance fee payment in a particular
     country, Dade Behring shall give Packard written notice of such decision,
     provided that, where feasible, Dade Behring shall give Packard such notice
     at least sixty (60) days prior to any deadline for taking action to
     maintain any Dade Behring Patent. Packard shall notify Dade Behring in
     writing, within thirty (30) days of the receipt of such notice whether
     Packard shall assume the responsibilities for the prosecution and
     maintenance of such Dade Behring Patent. Should Packard assume such
     responsibilities, Packard may take such action as may be necessary to
     maintain such patents, and may offset all costs of such action
     against royalty payments due pursuant to Article V; provided that Dade
     Behring and its Affiliates will have an irrevocable, royalty-free,
     world-wide, license, with the right to fully sublicense, to practice under
     such Dade Behring Patent. DADE BEHRING MAKES NO REPRESENTATIONS, CONDITIONS
     OR WARRANTIES, WHETHER EXPRESS OR IMPLIED, WITH REGARD TO THE VALIDITY OR
     ENFORCEABILITY OF THE DADE BEHRING PATENTS, OR THAT ANY MANUFACTURE,
     IMPORTATION, USE, SALE OF, OTHER DISPOSAL, REPRODUCTION OR ADAPTATION OF
     THE LABELS IS NOT AN INFRINGEMENT OF ANY PATENT, REGISTERED DESIGN,
     COPYRIGHT OR UNREGISTERED DESIGN RIGHT NOT VESTED IN DADE BEHRING, WITH THE
     SOLE EXCEPTION OF THE REPRESENTATION AND WARRANTY CONCERNING THE MCCAPRA
     PATENTS, SET FORTH ABOVE.

VII. TERM; TERMINATION

7.1  The initial term of this Agreement shall be for a period from the Effective
     Date through the last to expire of the Dade Behring Patents. Thereafter,
     the license granted pursuant to Article II, Section 2.1, shall convert to a
     royalty bearing, nonexclusive license for a period of ten years for
     Licensed Products. If Packard so requests, Dade Behring shall, pursuant to
     the terms of the Supply Agreement, continue to supply Packard with Labels
     and be the exclusive supplier of Labels.

7.2  Either party shall have the right to terminate this Agreement at any time
     for a material breach of this Agreement by the other party, provided that
     the nonbreaching party shall have first given [* * *] days prior written
     notice to the breaching party describing such breach and stating the
     nonbreaching party's intention to terminate this Agreement if such breach
     remains uncured, and the breaching party thereafter fails to cure such
     breach [***].

7.3  No termination hereunder shall constitute a waiver of any rights or causes
     of action that either party may have for any acts or omissions or breach
     hereunder by the other party prior to the termination date. Articles I,
     VIII, IX, X and Section 5.6 shall survive any termination of this
     Agreement, as well as such other provisions as, by their intent or meaning,
     are intended to so survive.

7.4  Except as expressly provided otherwise herein, any delays in or failures of
     performance by either party under this Agreement shall not be considered a
     breach of this Agreement if and to the extent caused by occurrences beyond
     the reasonable control of the party affected, including but not limited to:
     acts of God, new regulations or laws of any government; strikes or other
     concerted acts of workers; fire, floods, explosions; riots; wars;
     rebellion; and, sabotage, and any time for performances hereunder shall be
     extended by the time of delay reasonably occasioned by such occurrence.

     Technical Information relating to practice of LOCI disclosed to it (the
     "Receiving Party") by the other (the "Disclosing Party") in connection with
     this Agreement shall be considered confidential and proprietary and the
     Receiving Party shall not disclose same to any Third Party and shall hold
     it in confidence for a period of [* * *] from the date of disclosure
     and will not use it other than as permitted under this Agreement provided,
     however, that any information, know-how or data which is orally disclosed
     to the Receiving Party shall not be considered confidential and proprietary
     unless such oral disclosure is reduced to writing and given to the
     Receiving Party in written form within thirty (30) days after oral
     disclosure thereof. Such confidential and proprietary information shall
     include, without limitation, marketing and sales information,
     commercialization plans and strategies, research and development work
     plans, and Technical Information such as patent applications, inventions,

8.2  The obligations of confidentiality stated in the preceding Section shall
     not be applicable to the extent:

          a) such information is general public knowledge or, after disclosure
     hereunder, becomes general or public knowledge through no fault of the
     Receiving Party; or

          b) such information can be shown by the Receiving Party by its written
     records to have been in its possession prior to receipt thereof hereunder;

          c) such information is received by the Receiving Party from any Third
     Party for use or disclosure by the Receiving Party without any obligation
     to the Disclosing Party provided, however, that information received by the
     receiving Party from any Third Party funded by the Disclosing Party (e.g.
     consultants, subcontractors, etc.) shall not be released from
     confidentiality under this exception;

          d) the disclosure of such information is required or desirable to
     comply with or fulfill court orders, subpoenas, governmental requirements,
     submissions to governmental bodies, or the securing of regulatory
     approvals, provided, however, that the Disclosing Party first shall have
     given notice to the other Parties in order to permit the Disclosing Party
     to try to obtain a protective order requiring that the Information and/or
     documents so disclosed be kept confidential and used only for the purposes
     for which the order was issued; or

          e) such information is disclosed to employees or contractors of the
     Receiving Party or any Affiliate of the Receiving Party on a need to know
     basis, provided the Receiving Party takes reasonable precautions to
     preclude any further disclosure of such confidential information.

IX.  INDEMNITY

     Affiliates, and the directors, officers employees and agents of Packard and
     such Affiliates, and the successors and assigns of any of the foregoing
     (the "Packard Indemnitees"), from and against any and all liabilities,
     damages, losses, costs or expenses (including reasonable attorneys' and
     professional fees and other expenses of litigation and/or arbitration)
     resulting from a claim, suit or proceeding brought by a Third Party against
     a Packard Indemnitee for [* * *] (the "Lawsuit"). Dade Behring's total
     aggregate liability under this indemnification and for the warranties
     and representations made in Section 6.4 shall be limited to [* * *]

[* * *] Indicates information omitted pursuant to a request for confidential
treatment and filed separately with the Securities and Exchange Commission

as amended.

                                    Page 16


     [* * *]. In the event that a judgment or a settlement with Dade Behring's
     consent is rendered in a Lawsuit, Packard may credit a portion of such
     judgement or settlement against the royalty payments due and owing pursuant
     to Section 5.1 as follows:

     (a) the royalties due [* * *] must be paid without regard to such
     judgement;

     (b) in each reporting period, up to a maximum of [* * *] of the difference
     between the running royalties owed pursuant to Section 5.1 hereof and the
     royalties payable during such period under [* * *]; and

     (c) the credit must be taken in consecutive reporting periods to the extent
     of available running royalties.

     [* * *]

9.2  EXCEPT AS PROVIDED IN SECTION 9.1, DADE BEHRING SHALL BE UNDER NO LIABILITY
     WHATSOEVER TO PACKARD (WHETHER IN NEGLIGENCE OR OTHERWISE) FOR ANY EXPENSE,
     LOSS, DAMAGE OR INJURY OF ANY KIND (INCLUDING ANY LOSS OF PROFIT OR
     CONSEQUENTIAL DAMAGE) SUSTAINED BY PACKARD OR ANY THIRD PARTY ARISING OR
     INCURRED IN CONNECTION WITH THE RESEARCH AND DEVELOPMENT AND APPLICATION OF
     DADE BEHRING TECHNOLOGY BY PACKARD OR DERIVING DIRECTLY OR INDIRECTLY OUT
     OF THE PROVISION OR USE OF THE DADE BEHRING PATENTS OR DADE BEHRING
     TECHNOLOGY OR OTHERWISE ARISING OUT OF THE GRANT OF ANY RIGHTS HEREUNDER,
     OR THE PROVISION OF ANY INFORMATION IN CONNECTION HEREWITH.

9.3  Except for liabilities, damages, losses, costs or expenses arising from or
     related to a Lawsuit described Section 9.1, Packard shall indemnify, defend
     and hold harmless Dade Behring and its Affiliates, and the directors,
     officers, employees and agents of Dade Behring and such Affiliates, and the

     Indemnitees"), from and against [* * *]

                                    Page 17


9.4  If either party intends to claim indemnification under this Article IX, it
     shall promptly notify the other party (the "Indemnifying Party") in writing
     of any loss, claim, damage, liability or action and the Indemnifying Party
     shall have the right to assume the defense thereof with counsel mutually
     satisfactory to the parties. The indemnity agreement in this Article IX
     shall not apply to amounts paid in settlement of any loss, claim, damage,
     liability or action if such settlement is effected without the consent of
     the Indemnifying Party, which consent shall not be withheld unreasonably.
     The failure to deliver written notice to the Indemnifying Party within a
     reasonable time after the commencement of any such action, if prejudicial
     to its ability to defend such action, shall relieve the Indemnifying Party
     of any liability to the Indemnitee under this Section 9.4. At the
     Indemnifying Party's request, the Indemnitee and its employees and agents,
     shall cooperate fully with the Indemnifying Party and its legal
     representatives in the investigation of any action, claim or liability
     covered by this indemnification and provide full information with respect
     thereto.

X.   ADDITIONAL TRADEMARK PROVISIONS

10.1 If Packard, in its sole discretion, uses the Dade Behring Trademarks, it
     shall legibly apply the Dade Behring Trademarks to each item and all
     cartons and cases of and for each and every one of the Licensed Products
     manufactured, distributed or sold under this Agreement in a manner approved
     by Dade Behring. (Once approval is obtained, all similar materials may be
     marked in the same manner without additional approvals.) On advertising,
     promotional, packaging and wrapping material and any other such material
     wherein the Dade Behring Trademarks appear, the initials "TM" or (R) shall
     be used as directed by Dade Behring from time to time in connection with
     the Dade Behring Trademarks.

10.2 At all times during the Term of this Agreement, Packard shall maintain the
     quality standards set forth in this paragraph in connection with its use of
     the Dade Behring Trademarks. Packard shall not use the Dade Behring
     Trademarks other than in connection with the Licensed Products. The
     Licensed Products that bear the Dade Behring Trademarks shall be at least
     equal in quality to comparable unlicensed products as then manufactured and
     marketed by Packard. Dade Behring shall have the right to reasonably modify
     or supplement the quality standards applicable hereunder by providing
     written notice thereof to Packard with the express approval of Packard,
     which approval shall not be unreasonably


                                    Page 18


     withheld under the circumstances. Packard shall promptly furnish to Dade
     Behring, without cost, any samples of advertisements or other then existing
     uses of the Dade Behring Trademarks requested by Dade Behring. Dade Behring
     also shall have the right to inspect the Licensed Products and Packard's
     facilities and business operations to determine their conformity with the
     quality standards set forth herein. Technical meetings to address mutually
     important issues are to be held on an "as needed" basis.

10.3 Goodwill derived through use of the Dade Behring Trademarks inures to the
     benefit of Dade Behring. Packard recognizes the great value of the
     publicity and goodwill associated with the Dade Behring Trademarks and, in
     such connection, acknowledges that such goodwill, and all rights in the
     Dade Behring Trademarks, exclusively belong to Dade Behring. Packard
     further recognizes and acknowledges that a breach by Packard of any of its
     covenants, agreements or undertakings with regard to the Dade Behring
     Trademarks may cause Dade Behring irreparable damage, which cannot be
     readily remedied in damages in an action at law, and may in addition
     thereto, constitute an infringement of the Dade Behring Trademarks thereby
     entitling Dade Behring to immediate injunctive relief relative to products
     bearing the Dade Behring Trademarks, costs and reasonable attorneys' fees.

10.4 During the term hereof, Packard agrees that:

          (a) It will not attack the title of Dade Behring in and to the Dade
          Behring Trademarks, nor will it attack the validity of the trademark
          license granted hereunder;

          (b) It will not misuse the Dade Behring Trademarks;

          (c) It will manufacture, sell and distribute the Licensed Products
          that bear the Dade Berhing Trademarks in an ethical manner and in
          accordance with the terms and intent of this License Agreement;

          (d) It will not create any expenses chargeable to Dade Behring without
          the prior written consent of Dade Behring; and

          (e) It will comply with all laws and regulations relating or
          pertaining to this License Agreement or to the manufacture, sale,
          advertising or use of the Licensed Products; maintain the quality and
          standards required by this License Agreement; and comply with all
          requirements and regulations of any regulatory agencies which have
          jurisdiction over the Licensed Products.

10.5 Registration and any other protection for the Dade Behring Trademarks shall
     only be obtained by Dade Behring in its name and at its expense. Packard
     shall furnish


                                    Page 19


     to Dade Behring at its request any information about, and specimens
     illustrative of, the manner of use of the Dade Behring Trademarks by
     Packard. All use of the Dade Behring Trademarks by Packard and its
     Affiliates shall inure to the benefit of Dade Behring. Enforcement of the
     Dade Behring Trademarks by the institution of litigation or otherwise shall
     be in the sole discretion of Dade Behring, but Packard shall cooperate with
     Dade Behring by providing documentary evidence, employee testimony or the
     like in any enforcement action undertaken by Dade Behring. Dade Behring
     shall reimburse Packard for any out of pocket expenses incurred by Packard
     with regard to such cooperation. Packard shall notify Dade Behring in the
     event that Packard obtains information related to infringement of the Dade
     Behring Trademarks.

XI.  GENERAL

11.1 This Agreement shall be binding upon the parties' respective successors and
     permitted assigns. Neither party may assign this Agreement or any of its
     rights or obligations hereunder without the prior written consent of the
     other party (not to be unreasonably withheld), and any such attempted
     assignment shall be void; provided, that either party shall assign this
     Agreement as part of a merger or consolidation in which the surviving
     entity assumes all of such party's rights and obligations hereunder to such
     surviving entity and that either party shall assign this Agreement upon the
     sale of substantially all of the assets of such party to which this

     understandings are merged into, extinguished by and completely expressed by
     it. This Agreement, the Supply Agreement, and the Sublicense Agreement may
     be modified or amended only by a writing executed by authorized officers of
     each of the Parties.

11.4 This Agreement and its effects are subject to and shall be construed and
     enforced in accordance with the laws of the State of Delaware, U.S.A.,
     except as to any issue which depends upon the validity, scope or
     enforceability of any patent, which issue shall be determined in accordance
     with the applicable patent laws of the United States or the subject foreign
     country. The Parties agree that the exclusive jurisdiction and venue for
     any dispute or controversy arising from the Agreement shall be in the
     United States District Court for the District of Delaware if federal
     jurisdiction exists, and if no federal jurisdiction exists, then in the
     state courts of Delaware.

11.5 Nothing in this Agreement shall be construed so as to require the
     commission of any act contrary to law, and wherever there is any conflict
     between any provision of this Agreement or concerning the legal right of
     the Parties to enter into this Agreement and any statute, law, ordinance or
     treaty, the latter shall prevail, but in such event the affected provisions
     of the Agreement shall be curtailed and limited only to the extent
     necessary to bring it within the applicable legal requirements.

11.6 Should any provision of this Agreement be or become invalid, then the
     Parties hereto shall modify such invalid provision to render it valid and
     such that its economic effect comes as close as possible to that of the
     invalid provision. In any event, all other provisions of this Agreement
     shall be deemed valid and enforceable to the full extent possible.

11.7 The failure of any Party to take action for non-performance or for any
     breach of this Agreement shall not be construed as a general waiver or
     relinquishment of any such term or condition, or of the right to enforce or
     take advantage of the same in respect of any breach or non-observance
     thereof, either original or recurring.
