        6.1 Royalty. TWT shall pay STANFORD a running royalty of [****] of Net
Sales of Diagnostic Products sold by or under authority of TWT.

        6.2 Single Royalty/Non-Royalty Sales. In no event shall more than one
royalty be due hereunder with respect to any Diagnostic Product unit; nor shall
a royalty be payable under this Article 6 with respect to transfers of
Diagnostic Products for use in clinical trials or as samples.

        6.3 Combination Products. In the event that a Diagnostic Product is sold
in combination with another product, component or service for which no royalty
would be due hereunder if sold separately, Net Sales from such combination sales
for purposes of calculating the amounts due under this Article 6 shall be
calculated by multiplying the Net Sales of the combination product by the
fraction A/(A + B), where A is the average gross selling price during the
previous calendar quarter of the Diagnostic Product sold separately and B is the
gross selling price during the previous calendar quarter of the combined
product(s), component(s) and/or service(s). In the event that a substantial
number of such separate sales were not made during the previous calendar quarter
then the Net Sales shall be as reasonably allocated by TWT between such
Diagnostic Product and such other product(s), component(s) or service(s) based
upon their relative importance and proprietary protection.

        6.4 Records. TWT shall keep (or cause to be kept) complete and accurate
records of Net Sales in sufficient detail to enable the amounts payable under
this Article 6 to be determined. Upon STANFORD's written request, but not more
frequently than once per calendar year, TWT shall permit representatives or
agents of STANFORD, at STANFORD's expense, to examine such records during
regular business hours for the purpose of and to the extent necessary to verify
any report required under this Agreement with respect to Net Sales received not
more than three (3) years prior to the date of STANFORD's request. To the extent
that TWT does not have the right to grant STANFORD the right to audit its
sublicensees' books and records hereunder, TWT shall obtain for itself such
right and, at the request of STANFORD, TWT shall exercise such audit right with
respect to Sublicensees and provide the results of such audit for inspection by
STANFORD pursuant to this Section 6.4. In the event that the amounts due to
STANFORD are determined to have been underpaid, TWT shall pay to STANFORD any
amount due and unpaid, together with interest on such amount at the rate per
annum as quoted in the "Prime Rate" section of the "Money Rates" column of the
Wall Street Journal (U.S., Western Edition) on the date such amount was due, or
at the maximum rate permitted by law, whichever is lower.

        6.5 Reports/Payment. Beginning with the first accrual of Net Sales on
which a royalty is due hereunder, TWT shall provide to STANFORD a quarterly
royalty report as follows: Within ninety (90) days after the end of each
calendar quarter, TWT shall deliver to STANFORD a true and accurate report,
giving such particulars of the business conducted by or under authority of TWT,
if any, during such calendar quarter as are pertinent to account for royalties
due under this Article 6. Such report shall include at least (i) the total of
Net Sales during such quarter; (ii) the calculation of royalties; and (iii) the
total royalties so calculated and due STANFORD. Simultaneously with the delivery
of each such report, TWT shall pay to STANFORD the total royalties, if any, due
to STANFORD for the period of such report. If no royalties are due, TWT shall so
report. STANFORD shall not provide to third parties any information contained in
reports provided to STANFORD under this Section 6.5, or learned by STANFORD
under Section 6.4 above.

        6.6 Payments. All amounts payable hereunder by TWT shall be payable in
United States Dollars. If any currency conversion shall be required in
connection with the payment of royalties hereunder, such conversion shall be
made by using the exchange rates used by TWT in calculating TWT's own revenues
for financial reporting purposes.

                                   ARTICLE 7.

                              INTELLECTUAL PROPERTY

        7.1 Ownership of Inventions. Title to all inventions and other
intellectual property made solely by STANFORD personnel in connection with the
Development Program shall be owned by STANFORD. Title to all inventions and
other intellectual property made solely by TWT personnel in connection with the
Development Program shall be owned by TWT. Title to all inventions and other
intellectual property made jointly by personnel of TWT and STANFORD in
connection with the Development Program shall be jointly owned by STANFORD and
TWT. Except as expressly provided in this Agreement (including the rights
granted under Section 5.4 above), it is understood that neither party shall have
any obligation to account to the other for profits, or to obtain any approval of
the other party to license or exploit a joint invention, by reason of joint
ownership of any invention or other intellectual property and each party hereby
waives any right it may have under the laws of any country to require such
accounting or approval.

        7.2 Patent Prosecution.

               7.2.1 TWT Technology. TWT shall have the right, at its expense,
to control the preparing, filing, prosecuting and maintaining of solely owned
patent applications and patents within the TWT Technology worldwide, in such
countries as it deems appropriate, and the conducting of any interferences,
re-examinations, reissues, oppositions or requests for patent term extensions
relating to the TWT Technology using counsel of its choice.

               7.2.2 Program Technology. TWT, at its expense, shall have the
first right to pursue patent or other intellectual property protection for
Program Technology as the parties may mutually agree, and STANFORD agrees to
take all reasonable actions to cooperate with TWT in this regard. Intellectual
property rights claiming Program Technology owned solely by STANFORD shall be
prosecuted and maintained solely in STANFORD's name; and intellectual property
rights claiming Program Technology jointly owned by STANFORD and TWT shall be
prosecuted and maintained jointly in STANFORD's and TWT's names. In all such
events TWT shall keep STANFORD reasonably informed with respect to its
prosecution and maintenance of intellectual property protection for the Program
Technology and shall seek the advice of STANFORD with respect to such
prosecution and maintenance and shall give reasonable consideration to any
suggestions or recommendations of STANFORD concerning the preparation, filing,
prosecution and maintenance thereof. Without limiting the foregoing, in the
event that TWT fails or declines to take such actions with respect to any such
intellectual property rights, then STANFORD shall have the right to file,
prosecute and maintain such intellectual property rights at its sole expense and
the subject matter thereof shall no longer be within the definition of Program
Technology hereunder. In such event TWT shall notify STANFORD at least sixty
(60) days prior to the date the next action or filing is due to be taken with
respect to a jointly owned invention, patent application or patent, as to
whether TWT intends to take any of the foregoing actions with respect to such
invention, patent application or patent. Each party shall cooperate with the
other and assist the other in connection with their activities pursuant to this
Section 7.2.2, at the other party's request, and shall use good faith efforts to
consult with each other regarding the prosecution and maintenance of such
intellectual property rights as is reasonably appropriate.

        7.3 Enforcement.

               7.3.1 By TWT. Subject to the provisions of this Section 7.3, in
the event that TWT reasonably believes that any Program Technology is infringed
or misappropriated by a third party or is subject to a declaratory judgment
action arising from such infringement in such country within a field of use
licensed exclusively to TWT under Article 5 above, TWT shall have the initial
right (but not the obligation) to enforce (directly or through designees) any
intellectual property rights in and to the Program Technology with respect to
such infringement, or defend any declaratory judgment action with respect
thereto (for purposes of this Section 7.3, an "Enforcement Action").

               7.3.2 By STANFORD. In the event that TWT fails to initiate an
Enforcement Action to enforce such intellectual property rights in the Program
Technology within a reasonable period after a request by STANFORD to initiate
such Enforcement Action, STANFORD may initiate an Enforcement Action against
such infringement. The party initiating or defending any such Enforcement Action
shall keep the other party hereto reasonably informed of the progress of any
such Enforcement Action, and such other party shall have the right to
participate with counsel of its own choice.

                                      -8-

<PAGE>   9

               7.3.3 Recoveries. The party that controls any Enforcement Action
shall have the right to retain any recoveries received as a result of such
action. Notwithstanding the foregoing, to the extent an Enforcement Action is
directed to an activity (i) for which the parties would be obligated to share
proceeds under Section 5.5.2, any Net Recovery shall be shared equally between
the parties to the extent it relates to Therapeutic Applications or (ii) is
directed to a sale of a product which would be a Diagnostic Product if sold by
or under authority of TWT, any Net Recovery shall be treated as Net Sales
hereunder. For purposes of this Section 7.3.3, "Net Recovery" shall mean the
amount of the recovery received by the party initiating the Enforcement Action
less costs and expenses (including attorneys' and other professional fees)
incurred in connection with such Enforcement Action.

        7.4 Cooperation. With respect to the conduct of the activities provided
for in Sections 7.2 and 7.3 above, the party not controlling such activities
agrees to cooperate with the controlling party, as reasonably necessary for the
controlling party to conduct such activities. Without limiting the foregoing,
upon the reasonable request of and, at the expense of the party controlling such
activities, the other party shall join an action as a party-plaintiff, execute
such documents, and use reasonable efforts to make available at reasonable times
and under appropriate conditions all relevant personnel, records, papers,
information, samples, specimens and other similar materials in such other
party's possession.

                                   ARTICLE 8.

                         REPRESENTATIONS AND WARRANTIES

        8.1 TWT Warranties. TWT warrants and represents to STANFORD that (i) it
has the full right and authority to enter into this Agreement and grant the
rights and licenses granted herein; (ii) it has not previously granted and will
not grant any rights in conflict with the rights and licenses granted herein;
(iii) as of the date of the Agreement, TWT has not received from a third party
notice that the manufacture, sale or use of TWT Invader Squared Assays or
Standard Invader Reagent Plates would infringe any intellectual property rights
of such third party and to its knowledge and belief, no action, suit or claim
has been initiated or threatened against TWT with respect to the TWT Technology
or its right to enter into and perform its obligations under this Agreement; and
(iv) it has not previously granted, and will not grant during the term of this
Agreement, any right, license or interest in or to the TWT Technology, or any
portion thereof, to manufacture, sell or use a TWT Invader Squared Assay or
Standard Invader Reagent Plate that is in conflict with the rights or licenses
granted under this Agreement.

        8.2 Disclaimer of Warranties.


               8.2.1 BY TWT. EXCEPT AS PROVIDED IN SECTION 8.1 ABOVE, TWT
EXPRESSLY DISCLAIMS ANY WARRANTIES OR CONDITIONS, EXPRESS, IMPLIED, STATUTORY OR
OTHERWISE, WITH RESPECT TO THE DEVELOPMENT PROGRAM AND THE TWT TECHNOLOGY,
INCLUDING WITHOUT LIMITATION ANY WARRANTY OF MERCHANTABILITY, NONINFRINGEMENT,
OR FITNESS FOR A PARTICULAR PURPOSE, VALIDITY OF TWT TECHNOLOGY, PATENTED OR
UNPATENTED, AND NONINFRINGEMENT OF THE INTELLECTUAL PROPERTY RIGHTS OF THIRD
PARTIES.


               82.2 By Stanford. STANFORD MAKES NO WARRANTIES, EXPRESS OR
IMPLIED, AS TO ANY MATTER WHATSOEVER, INCLUDING, WITHOUT LIMITATION, THE RESULTS
OF THE DEVELOPMENT PROGRAM OR ANY INVENTION, PROCESS OR PRODUCT, WHETHER
TANGIBLE OR INTANGIBLE, CONCEIVED, DISCOVERED, OR DEVELOPED UNDER THIS
AGREEMENT; OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A PARTICULAR
PURPOSE OF THE DEVELOPMENT PROGRAM OR ANY SUCH INVENTION OR PRODUCT. STANFORD

                                   ARTICLE 9.

                                 INDEMNIFICATION

        9.1 Indemnification of STANFORD. TWT shall indemnify each of STANFORD
and its trustees, directors, officers, and employees of STANFORD and the
successors and assigns of any of the foregoing (each a "STANFORD Indemnitee"),
and hold each STANFORD Indemnitee harmless from and against any and all
liabilities, damages, settlements, penalties, fines, costs or expenses
(including, without limitation, reasonable attorneys' fees and other expenses of
litigation) arising out of any claim, complaint, suit, proceeding or cause of
action brought against a STANFORD Indemnitee by a third party (any of the
foregoing, a "Claim") alleging damage arising from or occurring as a result of
the Exploitation of any Program Technology by TWT or by a third party under
authority from TWT.

        9.2 Procedure. In the event that STANFORD intends to claim
indemnification under this Article 9 for itself or a STANFORD Indemnitee (the
"Indemnitee") STANFORD shall promptly notify TWT in writing of any Claim in
respect of which the Indemnitee intends to claim such indemnification, and TWT
shall have sole control of the defense and/or settlement thereof, provided that
the Indemnitee shall have the right to participate, at its own expense, with
counsel of its own choosing in the defense and/or settlement of such Claim. The
indemnification under this Article 9 shall not apply to amounts paid with
respect to settlement of any Claim if such settlement is effected without the
consent of TWT. The Indemnitee and STANFORD and its employees, at TWT's request
and expense, shall provide full information and reasonable assistance to TWT and
its legal representatives with respect to such Claims. It is understood that
only STANFORD may claim indemnity under this Article 8 (on its own behalf or on
behalf of a STANFORD Indemnitee), and other STANFORD Indemnitees may not
directly claim indemnity hereunder.


                                   ARTICLE 10.

breach or default prior to the expiration of the sixty (60) day period.

        10.3 Termination Upon Notice. STANFORD shall have the right to terminate
this Agreement upon sixty (60) days' prior written notice to TWT at anytime.

        10.4 Effects of Expiration or Termination. Termination of this Agreement
for any reason shall not release any party hereto from any liability which, at
the time of such termination, has already accrued to the other party or which is
attributable to a period prior to such termination nor preclude either party
from pursuing all rights and remedies it may have hereunder or at law or in
equity with respect to any breach of this Agreement.

        10.5 Survival. Articles 1, 6, 9, 10 and 11, and Sections 5.4, 5.5, 5.6,
7.1, 7.2.2, 7.3 and 8.2 shall survive expiration or termination of this
Agreement for any reason. Except as otherwise provided in this Article 10, all
rights and obligations of the parties under this Agreement shall terminate upon

                                   EXHIBIT 1.1

                     DEFINITION OF AGRICULTURAL APPLICATIONS

        "Agricultural Applications" shall mean applications relating to (i)
cultivating, characterizing or modifying soil; (ii) producing, growing,
improving, protecting, treating or modifying crops or forest products; (iii)
raising, harvesting, improving, protecting, treating or modifying livestock,
poultry, fish or shellfish; and (iv) the preparation, marketing or treatment of
products resulting from the activities described in (i)-(iii) above.
Agricultural Applications shall include applications involving the improvement
or modification of soil, crops, livestock, poultry, fish or shellfish and their
resulting products as they relate to human health, as well as foods from plants
and animals designed or modified to enhance their health attributes, in each
case for nutraceutical applications but not therapeutic applications in humans.
Agricultural Applications shall also include agricultural applications relating
to bacteria, fungi, and viruses, as well as pest organisms with respect to, and
only to the extent of, such bacteria, fungi, viruses or pest organisms'
interaction with soil, plants, livestock, poultry, fish or shellfish. For
avoidance of doubt it is acknowledged and understood that Agricultural
Applications includes genes and gene-based or genetic technologies useful for
achieving the above described activities, in particular:



         -  Gene-based assays for pesticide discovery;

         -  Gene-based diagnostics of agricultural pests;

         -  Gene-based analysis of metabolism of pesticides in plants and pest
            organisms;

         -  Gene-based analysis of metabolism and physiological state of plants;
            livestock, poultry, fish, shellfish, or their pests;

         -  Genetic modification of pest organism for functional analysis of
            pest-related properties;

         -  Genetic modification of pest, bacteria, fungi, or viruses for
            functional analysis and optimization as protectants or growth
            stimulators of plants, livestock, poultry, fish or shellfish;

         -  Functional genetic analysis of the genomes of plants, livestock,
            poultry, fish, or shellfish or their pest for applications in
            agriculture;

         -  Genetic modification of plants, livestock, poultry, fish, or
            shellfish or their pests with the goal of enhancing properties
            relevant to production and end-use (i.e.; input and output traits);

         -  Gene-based diagnostics for determining seed and crop composition and
            quality; and

         -  Gene-based markers for facilitation of the breeding of plants,
            livestock, poultry, fish, or shellfish or their pests for
            applications in agriculture.



        Agricultural Applications shall further include food safety applications
relating to crops or livestock up to the stage at which the crops are processed
into materials or food ingredients for human consumption or the livestock are
slaughtered (i.e., unprocessed food safety applications). Without limiting the
foregoing, the Agricultural Applications shall not include any application
relating to crops or livestock after the stage at which the corps are processed
into materials or food ingredients for human consumption or the livestock are
slaughtered (i.e., processed food applications).

        Agricultural Applications shall exclude all applications not expressly
described above. For avoidance of doubt, the Agricultural Applications shall in
no case include human applications (e.g., research, diagnostic or therapeutic)
nor any application for the discovery, production, or development of products
for therapeutic applications in humans, including without limitation, the
discovery, development, use and raising of animal models of human disease.
