promptly following its occurrence and which shall be subject to further
adjustment as provided in (b) below), and (III) completing such Phase of the
R&D Program for under the agreed upon Budget Cap as specified in Exhibit A.

(b) The specified completion date for each Phase (Ia-IV) of the R&D
Program shall be adjusted, for purposes of this Section 4.3 only, by adding
time for delays incurred in achieving successful completion of any prior Phases
to the timeframe specified in Exhibit A plus a grace period of up to one
hundred and eighty (180) days; provided, however, that (i) in no event shall
any such adjustment result in a specified completion date for any relevant
Phase of the R&D Program being adjusted to a date that is later than the
following number of days after the completion date for such Phase as specified
in Exhibit A: the sum of (A) one hundred and eighty (180) days, plus (B) the
time for delays actually incurred in achieving successful completion of any
prior Phases; and provided further, that (ii) in no event shall any such
adjustment result in a specified completion date for any Phase which is more
than eighteen (18) months from the completion date for such Phase as specified
in Exhibit A.

(c) Notwithstanding the foregoing Section 4.3(b), any delays that are
caused by MARTEK through the lack of timely performance of any of its
obligations under the Workplan shall result in the specified completion dates
being adjusted as needed to not penalize SEMBIOSYS for any such MARTEK delay.

(d) In the event that any Phase (I  IV) of the R&D Program is
successfully completed and is completed both on time and under budget, MARTEK
shall pay to SEMBIOSYS a milestone payment that is equivalent to one hundred
percent (100%) of the specified Budget Cap for such Phase less total expenses
billed to MARTEK for such Phase

pursuant to Section 4.2, provided, however, all such milestone payments,
if any, shall be separately accounted for by SEMBIOSYS and shall be kept
reasonably available to be used by SEMBIOSYS to fund any budget overruns in
future Phases of the R&D Program, and provided further that no additional
milestone payments shall be available once total expended and/or budgeted funds
for the R&D Program (including updated budgets for remaining Phases) have
reached a total of   *.

(e) In addition to the provisions of subsection (d) above, the parties
agree as follows: In the event that the parties agree to continue with Phase
Ib of the R&D Program despite lack of successful completion of Phase Ia of the
R&D Program, then upon the successful completion of Phase Ib of the R&D Program
both on time and under budget, any milestone payment that is due to SEMBIOSYS
for the successful completion of Phase Ib shall be equal to the combined Budget
Caps less the expenditures billed by SEMBIOSYS for Phase Ia and Phase Ib of the
R&D Program. Further, in the event that Phase Ia of the R&D Program is
successful and the parties agree to not engage in the work described for Phase
Ib, then any milestone payment that is due to SEMBIOSYS for the successful
completion of Phase Ia both on time and under budget shall be equal to the
combined Budget Caps less the expenditures billed by SEMBIOSYS for Phase Ia and
Phase Ib of the R&D Program.

4.4 Other Funding.

SEMBIOSYS will also assist MARTEK, upon request of MARTEK, in obtaining
economic incentives from the Canadian government related to the R&D Program and

Neither party may disclose the existence or terms of this Agreement
without the prior written consent of the other party; provided, however, that
either party may make such a disclosure to the extent required by law and that
SEMBIOSYS may make a disclosure of the existence and terms of this Agreement to
investors, prospective investors, lenders and other financing sources;
provided, however, that such disclosures shall only be made under the terms of
a confidentiality agreement providing protections similar to those contained
herein. The parties, upon the execution of this Agreement, will agree to a

Consultants.

Prior to retaining any consultant who shall have access to any
Confidential Information of the other party or who shall participate in the
performance of the R&D Program, each party shall use reasonable efforts to
determine if such consultant has or will have any potential conflict of
interest with respect to the other party as a result of any other relationships

7.PROVISIONS CONCERNING THE FILING, PROSECUTION,
MAINTENANCE AND ENFORCEMENT OF PATENT RIGHTS

7.1 Filing of Patents.

7.1.1 Primary Responsibilities.

(a)  MARTEK shall determine what Patent Rights will be filed in the
Territory on Inventions which are MARTEK Improvements. MARTEK shall also
determine what Patent Rights will be filed in the Territory on MARTEK
Inventions (other than SEMBIOSYS Improvements). MARTEK and SEMBIOSYS will
reasonably cooperate with each other to allow MARTEK to file and prosecute
patent applications relating to MARTEK Inventions (other than SEMBIOSYS
Improvements) and MARTEK Improvements.

(b)  SEMBIOSYS shall determine what Patent Rights will be filed in the
Territory on Inventions which are SEMBIOSYS Improvements. SEMBIOSYS shall also
determine what Patent Rights will be filed in the Territory on SEMBIOSYS
Inventions (other than MARTEK Improvements). MARTEK and SEMBIOSYS will

##### 



(c)  The parties will mutually agree on the filing and prosecution of any
Patent Rights on Joint Inventions which are not SEMBIOSYS Improvements or
MARTEK Improvements and shall share the costs associated with such patent
filing and prosecution as mutually agreed.

(d)  Responsibility for Patent Rights as described above shall include
responsibility for the filing, prosecution and maintenance (including the
defense of interferences and similar proceedings) of any such Patent Rights.

7.1.2 Elective Termination of Rights.

If at any time SEMBIOSYS wishes to discontinue the prosecution or
maintenance of any Patent Rights filed by it in accordance with Section 7.1.1
which are relevant to the Field, SEMBIOSYS shall promptly give notice of such
intention to MARTEK together with the reasons for such decision. In the event
that SEMBIOSYS decision is not based upon considerations of double-patenting,
lack of patentability, or potential interference, then MARTEK shall have the
right, but not the obligation, to assume responsibility for the prosecution of
any such Patent Rights at its own expense and in the name of SEMBIOSYS, by
giving notice to SEMBIOSYS of such intention within thirty (30) days and MARTEK
shall thereafter have a perpetual fully-paid license under such SEMBIOSYS
Patent Right for use in the Field. MARTEK shall thereafter keep SEMBIOSYS
reasonably informed as to the status of the prosecution, issuance and
maintenance of any such patent or patent application.

7.2 Expenses.

Each party will bear the costs of the filing, prosecution and maintenance
of all Patent Rights for which it has responsibilities pursuant to Section 7.1.

7.3 Legal Action.

7.3.1Actual or Threatened Infringement.

(a) In the event either party becomes aware of any possible infringement
or unauthorized possession, knowledge or use of any Patent Rights or Program
Know-How licensed hereunder (collectively, an Infringement), that party shall
promptly notify the other party and

24



---



##### 



provide it with full details. The parties will meet to determine the
appropriate course of action, and will collaborate in pursuing such course of
action.

(b) Notwithstanding the foregoing, if the parties do not otherwise agree
on a course of action, MARTEK shall have primary responsibility for the
prosecution, prevention or termination of any Infringement in the Field at
MARTEKs expense and with the sharing of recoveries as specified below. If
MARTEK does not commence an action on its own to prosecute, or otherwise take
steps to prevent or terminate, an Infringement of any Patent Right for which
SEMBIOSYS has primary responsibility pursuant to Section 7.1, the parties may
agree to jointly pursue an action, or if no such joint action is pursued within
ninety (90) days of any written request of SEMBIOSYS, then SEMBIOSYS shall have
the right and option to take such reasonable action as it considers appropriate
to prosecute, prevent or terminate such Infringement. If either party
determines that it is necessary or desirable for the other to join any such
suit, action or proceeding, the second party shall execute all papers and
perform such other acts as may be reasonably required in the circumstances.

(c) MARTEK shall bear the cost of any proceeding or suit under Section
7.3.1(b) brought by MARTEK and SEMBIOSYS shall bear the cost of any proceeding
or suit under Section 7.3.1(b) brought by SEMBIOSYS (for the purposes of this
Section each hereafter a responsible party). In each such case, the
responsible party shall have the right first to reimburse itself out of any
sums recovered in such suit or in its settlement for all reasonable costs and
expenses, including reasonable attorneys fees, related to such suit or
settlement. The remainder is next to be used to reimburse the other party for
its costs and expenses so incurred. Any remaining amounts shall be shared as
follows: 90% to the responsible party and 10% to the other party. Any
non-monetary recovery or award shall be shared as mutually agreed between the
parties hereto. The parties shall jointly bear the cost of any joint action
under Section 7.3.1(b) and shall share equally in any recovery. Each party
shall always have the right to be represented by counsel of its own selection
and at its own expense in any suit instituted under this Section by the other
party for an Infringement. If either party lacks standing and the other party
has standing to bring any such suit, action or proceeding as specified above,
then the other party shall do so at the request of the responsible party and at
the responsible partys expense.

25

##### 



(d) For Infringements outside the Field, the party owning or controlling
the relevant Patent Rights or Program Know-How as provided in Section 6.2 shall
have the right to pursue infringers, and the parties shall jointly agree on any
enforcement of Joint Program Intellectual Property outside the Field.

(e) In any action under this Section 7.3.1, the parties shall fully
cooperate with and assist each other. No suit under Section 7.3.1 regarding
SEMBIOSYS Patent Rights or Joint Patent Rights may be settled or compromised by
MARTEK without SEMBIOSYS consent. No suit under Section 7.3.1 regarding
MARTEK Patent Rights or Joint Patent Rights may be settled or compromised by
SEMBIOSYS without MARTEKs consent.

7.3.2 Defense of Claims Asserted by Third Parties.

Notwithstanding anything to the contrary in this Agreement, in the event
that any action, suit or proceeding is brought against SEMBIOSYS or any
Affiliate of SEMBIOSYS or MARTEK or any Affiliate, licensee or sublicensee of
MARTEK alleging the infringement of the intellectual property rights of a Third
Party by reason of the discovery, development, manufacture, use, sale,
importation or offer for sale of a Licensed Product by MARTEK or its
Affiliates, licensees or sublicensees, MARTEK will have the obligation to
defend itself and SEMBIOSYS and such Affiliate, licensee or sublicensee in such
action, suit or proceeding at MARTEKs expense, except if the action, suit or
proceeding is brought primarily due to the actions of SEMBIOSYS in its
development of transgenic plants, including but not limited to the use of
SEMBIOSYS proprietary technologies (in which case, MARTEK shall have no
obligation to defend SEMBIOSYS hereunder). SEMBIOSYS shall have the right to
separate counsel at its own expense in any such action or proceeding and MARTEK
will reimburse SEMBIOSYS for all reasonable expenditures incurred in connection
therewith. The parties will cooperate with each other in the defense of any
such suit, action or proceeding. The parties will give each other prompt
written notice of the commencement of any such suit, action or proceeding or
claim of infringement and will furnish each other a copy of each communication
relating to the alleged infringement. MARTEK shall not compromise, litigate,
settle or otherwise dispose of any such suit, action or proceeding which
involves SEMBIOSYS Program Intellectual Property or Joint Program Intellectual
Property without SEMBIOSYS advice and

26

##### 



prior consent, provided that SEMBIOSYS shall not unreasonably withhold its
consent to any settlement which does not have a material adverse effect on
SEMBIOSYS or SEMBIOSYS business.

8. LICENSE RIGHTS

##### 



assign or otherwise transfer its rights in the license granted herein (or
any part thereof) to its Affiliates. Notwithstanding any such assignment,
MARTEK shall be responsible for the activities, including all reporting and
royalty obligations, of such Affiliates as if they were MARTEK.

(b)  Subject to the terms and conditions of this Agreement, SEMBIOSYS
hereby grants to MARTEK a sole and exclusive license in the Territory to make,
have made, use, have used, import, have imported, offer for sale, sell and have
sold Licensed Products in the Field solely as it relates to DHA, with rights to
grant sublicenses that are co-extensive with such license, under any and all
SEMBIOSYS Background Technology. MARTEK shall have the right to assign or
otherwise transfer its rights in the license granted herein (or any part
thereof) to its Affiliates. Notwithstanding any such assignment, MARTEK shall
be responsible for the activities, including all reporting and royalty
obligations, of such Affiliates as if they were MARTEK.

(c)  Subject to the terms and conditions of this Agreement and the specific
limitations set forth in Section 8.1.2(d), SEMBIOSYS hereby grants to MARTEK an
exclusive sublicense in the Territory under the Third Party Licenses solely to
the extent necessary to allow MARTEK to practice the licenses granted in
subsections (a) and (b) above as they relate to DHA. MARTEK shall not have the
right to assign or otherwise transfer its rights in the license granted herein
(or any part thereof) without the prior written consent of SEMBIOSYS, which
consent shall not be unreasonably withheld. SemBioSys shall cooperate with
Martek in good faith to secure any rights for Martek under such Third Party
Licenses directly from the relevant licensors upon the occurrence of the
relevant events, and on the terms and conditions, in each case as expressly
provided in the relevant Third Party License.

(d)  Notwithstanding subsection (c) above, MARTEK shall have no right under
the Third Party Licenses to make or have made transgenic plants capable of

capable of producing DHA or produce seed of transgenic plants capable of
producing DHA until the expiration of all relevant patents licensed to
SEMBIOSYS under the Third Party Licenses except as otherwise expressly provided
in any such Third Party License as in effect on the Effective Date. Prior to
the patent

28



---



##### 



expiration of all relevant patents licensed to SEMBIOSYS under the Third
Party Licenses, SEMBIOSYS shall propagate plant material and/or produce seed
from transgenic plants producing DHA as an exclusive contract manufacturer for
MARTEK pursuant to a Supply Agreement to be negotiated in good faith by the
parties and agreed to prior to the first anniversary of the Effective Date.
Such Supply Agreement shall specify that material to be provided for use in the
R&D Program shall be paid for as an R&D Program cost in accordance with Section
4.2 hereof and that material to be provided for use in commercialization of DHA
shall be paid for at a cost that includes reasonable manufacturing margins
provided that such cost shall not be greater than the cost to MARTEK should it
have the right to propagate the transgenic plant material itself.
Notwithstanding the foregoing, in the event that at any time during the term of
the Supply Agreement SEMBIOSYS and/or its existing subcontractors are unable to
propagate plant material and/or produce seed from transgenic plants producing
DHA as an exclusive contract manufacturer for MARTEK, SEMBIOSYS agrees that, at
MARTEKs request, it will subcontract propagation of relevant plant material
and/or the production of relevant transgenic plants and/or seeds in accordance
with the Third Party Licenses, to MARTEK and/or MARTEKs qualified designees.
In the event that material generated through such subcontracting activities is
transferred to or from SEMBIOSYS as part of the subcontracting activities
pursuant to the foregoing sentence, SEMBIOSYS agrees that it will only charge
MARTEK the direct costs associated with any such transfer.

8.1.3
No Other Rights.

Neither party shall receive any rights to utilize any proprietary rights
owned or controlled by the other party except as expressly set forth herein.

8.3 Licenses and Sublicenses to Third Parties.

If MARTEK grants a license or sublicense as permitted herein to a Third
Party with respect to any SEMBIOSYS Background Technology, SEMBIOSYS Program
Intellectual Property, and/or Joint Program Intellectual Property, MARTEK shall
guarantee that such licensee or sublicensee will fulfill all of MARTEKs
obligations under this Agreement; provided, however, that MARTEK shall remain
directly liable for the fulfillment of all such obligations unless otherwise
consented to in writing by SEMBIOSYS.

8.4 Payment of Royalties, Accounting for Royalties and Records.

8.4.1 Royalties on Sales of DHA.

In consideration of the licenses granted to MARTEK pursuant to this
Agreement with respect to DHA, MARTEK shall pay to SEMBIOSYS a royalty as
determined below on sales of Licensed Products equal to  *  of (i) the
Gross Margin realized by MARTEK on the sales of such Licensed Products by
MARTEK or its Affiliates, and (ii) any royalties or other license income
received during the License Term by MARTEK as consideration for a license or
sublicense of Licensed Products. Notwithstanding any other provision hereof,
all sales of Licensed Products to distributors, whether or not made with
restrictions as to use or resale, shall be deemed sales by MARTEK and not
licenses of Licensed Products for purposes of the foregoing.

The
royalty rate shall vary  *   depending on (a) the
Development Contribution as set forth in the table below as determined based on
the stage of development of the Licensed Product at the time of any termination
of the R&D Program and this Agreement (if such termination occurs) and/or
completion of Phase IV of the R&D Program, and (b) the level of DHA in the
resulting commercial crop (the DHA Royalty Contribution). The Development
Contribution and the DHA Royalty Contribution will be determined in accordance
with the following tables:

8.4.4 Accounting.

The Gross Margin used for computing the royalties payable to SEMBIOSYS
hereunder shall be computed, and royalties shall be paid, in U.S. dollars. For
purposes of determining the amount of royalties due, the amount of sales or
revenues in any foreign currency shall be computed by converting such amount
into U.S. dollars at the prevailing commercial rate of exchange for purchasing
dollars with such foreign currency as reported in The Wall Street Journal on
the last business day of the period to which a royalty payment relates.

8.4.5 Records.

MARTEK, its Affiliates, licensees and sublicensees shall keep for three
(3) years from the date of each payment of royalties complete and accurate
records of sales by MARTEK and its Affiliates, licensees and sublicensees of
each Licensed Product as well as cost of sales, licensing income and percentage
DHA calculations in sufficient detail to allow the accruing royalties to be
determined accurately. SEMBIOSYS shall have the right for a period of three
(3) years after receiving any report or statement with respect to royalties due
and payable to appoint an independent certified public accountant reasonably
acceptable to MARTEK to inspect the relevant records of MARTEK and its
Affiliates, licensees and sublicensees to verify such report or statement.
MARTEK and its Affiliates, licensees and sublicensees shall make its records
available for inspection by such independent certified public accountant during
regular business hours at such place or places where such records are
customarily kept, upon reasonable notice from SEMBIOSYS, solely to verify the
accuracy of the reports and payments. Such inspection right shall not be
exercised more than once in any Calendar Year nor more than once with respect
to sales of any Licensed Product in any given Calendar Quarter. SEMBIOSYS
agrees to hold in strict confidence all information concerning royalty payments
and reports, and all information learned in the course of any audit or
inspection, except to the extent necessary for SEMBIOSYS to reveal such

8.4.6 Overdue Royalties.

Royalties not paid within the time period set forth in Section 8.4.3 shall
bear interest at a rate of one percent (1%) per month from the due date until
paid in full.

8.4.7 Royalties on ARA and EPA.

Unless otherwise provided in any agreement entered into pursuant to
Section 3.1.1, in the event that MARTEK develops an ARA or EPA product in the
Field which is a Licensed Product, MARTEK and SEMBIOSYS shall negotiate in good
faith an appropriate royalty within a range  *   of the Gross Margin on sales of such a Licensed Product which
shall take into account the contributions of SEMBIOSYS to the development of
any such Licensed Product using a structure similar to that set forth in
Section 8.4.1. Such royalty shall be negotiated upon request of MARTEK, but in
any event prior to the first introduction of a nucleic acid construct relating
to EPA or ARA metabolism into a commercial crop which is a Licensed Product.
MARTEKs obligations and SEMBIOSYS rights set forth in Sections 8.4.3, 8.4.4,
8.4.5, and 8.4.6 shall apply to all sales of any such Licensed Products
containing ARA or EPA. Nothing in this Section 8.4.7 shall affect any

Licensed Products containing DHA. Any royalty for an ARA or EPA product
negotiated pursuant to this Section 8.4.7 shall be structured to include tables
similar to those tables set out in Section 8.4.1 (I) and (II) above, but with
different percentages and different factors used to determine when each such
percentage applies.

8.5 Commercialization Efforts.

MARTEK agrees that it will use commercially reasonable efforts to develop
and market Licensed Products in the Field throughout the Territory at its own
expense, but only to the extent that the development and commercialization of
such Licensed Products is economically practicable and the market for such
Licensed Products justifies, in MARTEKs sole discretion, such development and
sale.

known to both parties as quickly as possible by delivering written notice of
their decision to both parties. The parties shall agree in writing to comply
