account of any such obligations.  In the event that the JSC determines
to Develop a Product that would require the payment of a royalty under [*], Ono
shall also pay all royalty payments under [*].  Notwithstanding the
foregoing, if during the Term, Ono enters into an agreement with a Third Party
to license Patent Rights in the Territory that would, but for such license, in
the written reasoned opinion of Ono’s outside patent counsel (which written
opinion shall be reasonably acceptable to Progenics), be infringed by the
Development, manufacture, use, sale, offering for sale, importation, exportation
or other Commercialization or exploitation of any Product in the Territory
(“Third Party
License”), then with respect to such Product, Ono and its Affiliates may
deduct up to [*] of the royalties payable pursuant to such Third Party License
actually paid by Ono to such Third Parties with respect to such Product from the
royalties otherwise due to Progenics with respect to the Net Sales of such
Product in the Territory under Section 6.4.1 ([*] Royalty Period), and 6.4.2
([*] Royalty Period) provided that such withholding shall not in any Calendar
Quarter reduce the royalties otherwise due to Progenics with respect to the Net
Sales of such Product in the Territory under Section 6.4.1 ([*] Royalty Period)
and Section 6.4.2 ([*] Royalty Period) by more than [*] percentage
points.  For clarity and by way of example, if the royalty rate
otherwise payable to Progenics for the Product is [*], the royalty rate after
such withholding shall in no event be less than [*].

and Payments.




6.5.1.  Cumulative
Royalties.  The obligation to pay royalties under this
Agreement shall be imposed only once with respect to any sale of any Product,
regardless of the number of patents that may cover the Product.




6.5.2.  Royalty Statements and
Payments.  Within [*] days of the end of each Calendar Quarter,
Ono shall deliver to Progenics a report, setting forth in reasonable detail for
such Calendar Quarter, the following information, on a Product-by-Product basis:
(a) Net Sales of the Product, (b) the amounts and types of Permitted Deductions
taken, (c) the amount and types of the Product provided at no charge, and
(d) the royalty due under this Agreement for the sale of the
Product.  The royalty shall be calculated and paid quarterly as
follows:




(a)  Ono shall
calculate the royalty due to Progenics based upon the Net Sales of all Products
by Ono during the first quarter of each Ono Fiscal Year (ending June 30) (“1Q”) (“1Q Royalty”) and Ono
shall make such payment to Progenics.




(b)  Ono shall
calculate the royalty due to Progenics based upon the Net Sales of all Products
by Ono for 1Q and the second quarter of each Ono Fiscal Year (“2Q”) and this shall
be “September 30 YTD
Royalties”.  Ono shall deduct 1Q Royalty from September 30 YTD
Royalties to arrive at the amount which is due to Progenics for 2Q and Ono shall
make such payment to Progenics.




(c)  Ono shall
calculate the royalty due to Progenics based upon the Net Sales of all Products
by Ono for 1Q, 2Q and the third quarter of each Ono Fiscal Year (“3Q”) and this shall
be “December 31 YTD
Royalties”.  Ono shall deduct September 30 YTD Royalties from
December 31 YTD Royalties to arrive at the amount which is due to Progenics for
3Q and Ono shall make such payment to Progenics.




(d)  Ono shall
calculate the royalty due to Progenics based upon the aggregated Net Sales of
all Products by Ono for 1Q, 2Q, 3Q and the final quarter of an Ono Fiscal Year
(“4Q”) (“Full Ono Fiscal Year
Royalties”).  Ono shall deduct December 31 YTD Royalties from
Full Ono Fiscal Year Royalties to arrive at the amount which is due to Progenics
for 4Q and Ono shall make such payment to Progenics.

Ono is so required to make any deduction or withholding from payments due to
Progenics, Ono will (a) promptly notify Progenics of such requirement, (b) pay
to the relevant authorities on Progenics’ behalf the full amount required to be
deducted or withheld promptly upon the earlier of determining that such
deduction or withholding is required or receiving notice that such amount has
been assessed against Progenics, and (c) promptly forward to Progenics an
official receipt (or certified copy) or other documentation reasonably
acceptable to Progenics evidencing such payment to such
authorities.  Ono shall, at the request of Progenics, use Commercially
Reasonable Efforts in cooperation with Progenics to apply and qualify for all
exemptions and other positions available to Progenics and its Affiliates under
Japanese law and Article 22 of the Income Tax Convention between Japan and the
United States with a view to achieving the maximum lawful reduction of Japanese
withholding and other taxes payable by Progenics.




6.5.4.  Currency.  All
payments under this Agreement shall be made in United States
dollars.  All such payments shall be translated into United States
dollars at the exchange rate for conversion of Japanese Yen into United States

shall keep and shall cause its Affiliates to keep books and accounts of record
in connection with the sale of the Product, in accordance with GAAP and in
sufficient detail to permit accurate determination of all figures necessary for
verification of royalties to be paid under this Agreement.  Ono and
its Affiliates shall maintain such records for a period of at least [*] after
the end of the Calendar Quarter in which they were generated, provided, however, that if
any records are in dispute and Ono has received written notice from Progenics of
the records which are in dispute, Ono shall keep such records until the dispute

6.5.6.  Audits.  Upon thirty
(30) days’ prior written notice from Progenics, Ono shall permit an independent
certified public accounting firm of nationally recognized standing
selected by Progenics and reasonably acceptable to Ono, to examine, at
Progenics’ sole expense, the relevant books and records of Ono and its
Affiliates as may be reasonably necessary to verify the amounts reported by Ono
in accordance with Section 6.5.2 (Royalty Statements and Payments) and the
payment of royalties under Section 6.4 (Royalty Payments).  An
examination by Progenics under this Section 6.5.6 (Audits) shall occur not more
than once in any Calendar Year and shall be limited to the pertinent books and
records for any Calendar Year ending not more than [*] before the date of the
request.  The accounting firm shall be provided access to such books
and records at Ono’s facilit(y/ies) where such books and records are normally
kept and such examination shall be conducted during Ono’s normal business
hours.  Ono may require the accounting firm to sign a standard
non-disclosure agreement before providing the accounting firm access to Ono’s
facilities or records.  Upon completion of the audit, the accounting
firm shall, subject to Section 6.5.8 (Confidentiality) provide both Ono and
Progenics with a written report disclosing any discrepancies in the reports
submitted by Ono or the royalties paid, and, in each case, the specific details
concerning any discrepancies.




6.5.7.  Underpayments/Overpayments.  If
such accounting firm concludes that additional royalties were due to Progenics,
Ono shall pay to Progenics the additional royalties within [*] days of the date
Ono receives such accountant’s written report, plus interest, which shall be
calculated at the average of the prime rate reported by JPMorgan Chase, New York
City, each month during the period from the time any royalty payment was due
until paid in full, plus [*] per annum.  If such underpayment exceeds
[*] of the royalties that were to be paid to Progenics, Ono also shall reimburse
Progenics for the out-of-pocket expenses incurred in conducting the
audit.  Progenics shall not reveal to such accounting firm the
conditions under which the audit expenses are to be reimbursed
hereunder.  If such accounting firm concludes that Ono overpaid
royalties to Progenics, Progenics will refund such overpayments to Ono, within
[*] days of the date Progenics receives such accountant’s report.  No
interest shall be due Ono on such overpayment.




6.5.8.  Confidentiality.  All
progress reports and financial information of Ono which are subject to review
under this Section 6 (Payments by Ono to Progenics) shall be deemed to be Ono’s
Confidential Information subject to the provisions of Section 8
(Confidentiality) hereof, and Progenics shall not disclose such Confidential
Information to any Third Party or use such Confidential Information for any
purpose other than reviewing progress made or verifying payments to be made by
Ono to Progenics under this Agreement; provided, however, that such
Confidential Information may be disclosed by Progenics to Third Parties only to
the extent necessary to enforce Progenics’ rights under this
Agreement.

not be prepared, filed, prosecuted or maintained in the Territory, Progenics
shall, subject to Wyeth’s rights under the Wyeth Agreement and the Partial
Termination Agreement, use Commercially Reasonable Efforts to prepare, file,

Technology that may be patentable, and shall cause their respective patent
counsel to communicate regularly regarding the prosecution and maintenance of
the Joint Patent Rights in the Territory and outside the
Territory.  With respect to all Joint Technology for which the Parties
agree patent prosecution should be sought, the Parties shall cooperate in the
preparation, filing and prosecution of patent applications (including provoking,
instituting or defending interference, opposition, revocation, reexamination and
similar proceedings related to the Joint Patent Rights), and shall discuss and
agree on the content and form of relevant patent applications and any other

shall serve as the lead Party outside the Territory to prosecute and maintain
all applications covering Joint Patent Rights (including provoking, instituting
or defending interference, opposition, revocation, reexamination and similar

borne by Ono in the Territory and by Progenics outside the Territory, unless
otherwise agreed by the Parties.  In the event that the Parties, after

decisions relating to interference, opposition, revocation, reexamination and
similar proceedings related to the Joint Patent Rights), Ono shall make such

business days prior to the earlier of the expiration of any shortened statutory
period for response or anticipated filing to review and comment upon the text of
any such communication.  Ono also shall keep Progenics advised on the
maintenance of any patents included within the Ono Collaboration Patent Rights
and provide Progenics with a reasonable opportunity to comment on
maintenance.  In the event that the Parties, after good faith
discussions, cannot agree with respect to any decision to be made with respect

event, however, shall Ono take any action that would cause a breach of any
Progenics Third Party Agreement or that would materially interfere with
Progenics’ worldwide intellectual property strategy regarding the Compound or
related formulations thereof.  In the event Ono elects not to prepare,
file, prosecute or maintain any Ono Collaboration Patent Rights, it shall give
Progenics notice to this effect, sufficiently in advance to permit Progenics to
undertake such filing, prosecution and maintenance without a loss of rights,
and, thereafter, Progenics may, upon written notice to Ono, file and

7.2.8.  Infringement
and Third Party Licenses.




(a)  Infringement of Third Party Patents -
Course of Action.  If the performance of the Licensed
Activities by Ono or any of its Affiliates is alleged by a Third Party to
infringe a Third Party’s patent or other intellectual property right, the Party
becoming aware of such allegation shall promptly notify the other
Party.  Additionally, if either Party determines that, based upon the
review of a Third Party’s patent or patent application or other intellectual
property rights, it may be desirable to obtain a license from such Third Party
with respect thereto so as to avoid any potential suit between either Party and
such Third Party, such Party shall promptly notify the other Party and the JSC
of such determination and initiate discussions to determine whether such license
is desirable.




(b)  Ono Option to
Negotiate.  Subject to Section 7.2.8(c) (Third Party
Infringement Suit) and Section 6.4.3 (Third Party Agreements), in the event that
Ono determines that, in order for Ono or its Affiliates to engage in the
Licensed Activities, it is necessary or desirable for Ono or its Affiliate to
obtain a license under one or more patents or patent applications or other
intellectual property rights owned or controlled by a Third Party (collectively,
“Third Party IP
Rights”), Ono shall have the first right, but not the obligation, to
negotiate and enter into an agreement with such Third Party, whereby Ono is
granted a license under such Third Party IP Rights permitting Ono and its
Affiliates to practice such Third Party IP Rights in connection with the
Licensed Activities and the performance of any of its obligations or the
exercise of any of its rights under this Agreement; provided, however, that in no
event shall Ono enter into such agreement without Progenics’ prior written
consent, which consent shall not be unreasonably withheld.




(c)  Third Party Infringement
Suit.  If a Third Party sues Ono or any of Ono’s Affiliates
(each Person so sued being referred to herein as a “Sued Party”),
alleging that the Licensed Activities of Ono or any of Ono’s Affiliates during
the Term of and pursuant to this Agreement infringe or will infringe such Third
Party’s patent, then, upon Ono’s request and in connection with the Sued Party’s
defense of any such Third Party infringement suit, Progenics shall provide
reasonable assistance to the Sued Party for such defense.




7.2.9.  Compliance.  Subject
to the specific provisions of this Agreement, Ono shall be responsible for, and
use Commercially Reasonable Efforts to make, all filings required by any
Regulatory Authority in the Territory.

(e)  it shall

activities under this Agreement.




9.2.  Additional Representations and
Warranties of Progenics.   In addition to the
representations and warranties made by Progenics elsewhere in this Agreement,
Progenics, hereby represents, warrants and covenants to Ono that:




(a)  Schedule 9.2(A)
identifies all Progenics Patent Rights owned by Progenics in the Territory (the
“Owned Progenics
Patent Rights”), and Schedule 9.2(B)
identifies all Progenics Patent Rights which Progenics licenses from Third
Parties in the Territory (the “Licensed Progenics Patent
Rights”), in each case along with the following information with respect
to each identified Patent Right, as applicable: (i) country, (ii) title, (iii)
application number, (iv) application filing date, (v) patent number, (vi) patent
issue date, (vii) listed inventor(s), and (viii) current owner.  Schedule 9.2(C)
identifies each Progenics Third Party Agreement that provides for Patent Rights
or Know-How necessary for the Development and Commercialization of the Compound
and Products in the Territory.  The Owned Progenics Patents Rights and
the Licensed Progenics Patent Rights identified on Schedules 9.2 (A) and
(B)) constitute
all of the Progenics Patent Rights as of the Effective Date.




(b)  To its
knowledge and except as described in Schedule 9.2(D),
Progenics exclusively owns all rights, title, and interest in the Owned
Progenics Patent Rights and owns or Controls the Progenics Know-How existing as
of the Effective Date in the Territory free and clear of any licenses, or other
claim of right or ownership by any Third Party.  Neither any license
granted by Progenics to any Third Party, nor any license granted by any Third
Party to Progenics, conflicts with the license grants to Ono under this
Agreement.




(c)  Progenics
has and will have the full right, power and authority to grant the licenses
granted or to be granted to Ono under this Agreement.




(d)  There are
no Progenics Third Party Agreements that provide for Patent Rights or Know-How
necessary to engage in the Licensed Activities other than the agreements
identified in Schedule
9.2(C).  As of the Effective Date, no Third Party has any
right, title or interest in or to, or any license under, any of the Progenics
Patent Rights in the Territory other than as provided in Progenics Third Party
Agreements or the Wyeth Agreement.

Execution

(e)  To the
extent that any of the Progenics Patent Rights arose from work funded in whole
or in part by United States federal funding, to Progenics’ knowledge all
requirements necessary to (i) vest the entire right, title and interest in
Progenics or Progenics’ licensor of such Progenics Patent Rights, and (ii) grant
the licenses to Progenics under Patent Rights licensed to Progenics, have been
satisfied.




(f)  To
Progenics’ knowledge, as of the Effective Date and except for the Patent Rights
that Progenics has previously disclosed to Ono in writing, the Development and
Commercialization by Ono of the Initial Formulation and the Product do not
infringe any issued patent owned or possessed by any Third Party in the
Territory.  As of the Effective Date, there are no outstanding orders,
judgments or settlements against or owed by Progenics relating to the Progenics
Technology that would adversely affect Ono’s ability to engage in the Licensed
Activities, and there is no pending or, to the best of its knowledge,
threatened, claims or litigation, relating to the Progenics Technology that
would adversely affect Ono’s ability to engage in the Licensed
Activities.




(g)  As of the
Effective Date, the Progenics Third Party Agreements that provide for Patent
Rights or Know-How necessary for the Development and Commercialization of the
Compound and Products in the Territory are in full force and effect, and
Progenics is in compliance in all material respects with such Progenics Third
Party Agreements. To Progenics’ knowledge, no event or omission has occurred,
and no circumstances exist, which, with or without the giving of notice and/or
the passage of time, would permit the counterparty to terminate any such
Progenics Third Party Agreement.




(h)  During
the Term (i) Progenics will use Commercially Reasonable Efforts not to take or
omit to take any actions the taking or omission of which would breach any
Progenics Third Party Agreement, or other agreements between Progenics and Third
Parties, that provide for Patent Rights or Know-How necessary for the
Development and Commercialization of the Compound and Products in the Territory,
and (ii) Progenics will, subject to any obligations of confidentiality, provide
Ono promptly with notice of any allegation that Progenics has breached any such
agreement.  During the Term, Progenics will not enter into any
agreement with any Third Party adversely affecting the rights granted to Ono
under this Agreement.




9.3.  Additional Representation and
Warranty of Ono.  In addition to the representations and
warranties made by Ono elsewhere in this Agreement, Ono, hereby represents,
warrants and covenants to Progenics that, as of the Effective Date, Ono has no
product or compound in pre-clinical or clinical development that would be
competitive with, or is intended to treat similar indications to those of, any
Product.

      AND TERMINATION




10.1.  Term.  The term of
this Agreement (the “Term”) will commence
on the Effective Date and extend on a Product-by-Product basis, unless this
Agreement is terminated earlier in accordance with this Section 10 (Term and
Termination), until the last to expire of the applicable [*] Royalty Period or

10.2.  Termination
by Progenics.




10.2.1.  General.  Progenics
may terminate this Agreement at any time by giving written notice to Ono in the
event that Ono commits a material breach of its representations, warranties,
covenants or obligations, including [*] as provided for in Section 4.3 ([*]
Development Activities), under this Agreement and such material breach remains
uncured for ninety (90) days (or thirty (30) days for a breach of a payment
obligation) measured from the date written notice of such material breach is
given to Ono; provided,
however, that if any breach other than non-payment is curable, but not
reasonably curable within ninety (90) days, and so long as Ono is using
Commercially Reasonable Efforts to cure such breach, such termination shall be
delayed for a reasonable period of time in order to permit Ono reasonable time
to cure such breach.




10.2.2.  Payment
Breaches.  Without limitation, failure by Ono to pay any amount
in excess of [*] within the cure period specified in this Section 10.2
(Termination by Progenics) shall constitute a material breach of this
Agreement.  If the alleged material breach relates to non-payment of
an amount that is subject to a bona fide good faith dispute between the Parties
as to whether such payment is due, the thirty (30) day cure period shall be
tolled pending resolution of such dispute; provided, however, that if
such amount is part of a larger payment due, only the cure period for the amount
in dispute shall be tolled.




10.3.  Termination
by Ono.




10.3.1.  Termination by Ono Because of Serious
Safety, Efficacy or Commercial Reasons.If one or more safety, efficacy
or commercial issues arise with respect to a Product which are sufficiently
serious that Ono would cease Development or Commercialization of the Product if
the Product were a product or proposed product owned solely by it, or to which
it had exclusive rights, that were of similar commercial potential and at a
similar stage in its development or product life, Ono shall promptly inform
Progenics of such safety, efficacy or commercial issues(s) and convene a meeting
of the JDC or, as appropriate, JCC to discuss such safety, efficacy or
commercial issues and their implications for Development and Commercialization
of the Product.  If the JDC or JCC is unable to agree on a plan to
continue Development and Commercialization of the Product, then the matter will
be referred to the JSC for discussion.  If the JSC is unable to agree
on a plan to continue Development and Commercialization of the Product, [*] will
discuss whether there is any viable alternative to ceasing Development and
Commercialization and decide how to resolve any dispute or controversy between
the Parties relating to this matter.

or institution of bankruptcy, liquidation or receivership proceedings (other
than reorganization proceedings under Chapter 11 of the United States Bankruptcy
Code) with respect to the Debtor Party, (c) upon an assignment of a substantial
portion of the assets for the benefit of creditors by the Debtor Party, (d) in
the event a receiver or custodian is appointed for the Debtor Party’s business,
or (e) if a substantial portion of the Debtor Party’s business is subject to
attachment or similar process; provided, however, that in
the case of any involuntary bankruptcy proceeding such right to terminate shall
become effective only if the proceeding is not dismissed within sixty (60) days
after the filing thereof.  To the extent permitted by applicable law,
the effect of a termination under this Section 10.5.1 (Termination) shall be as
described in Section 10.4.1 (Upon Termination By Progenics) in case of the
Debtor Party is Ono, and in Section 10.4.3 (Effect of Termination by Ono for

10.5.2.  Effect on
Licenses.  All rights and licenses granted under or pursuant to
this Agreement are licenses of rights to “intellectual property” as defined in
Section 365(n) of Title 11 of the United States Code (“Title
11”).  Each Party agrees that the other Party, as licensee of
such rights under this Agreement shall retain and may fully exercise all of its
rights and elections under Title 11.  Each Party agrees during the
Term, to create and maintain current copies or, if not amenable to copying,
detailed descriptions or other appropriate embodiments, to the extent feasible,
of all such intellectual property.  If a case is commenced by or
against the Debtor Party under Title 11, the Debtor Party (in any capacity,
including debtor-in-possession) and its successors and assigns (including,
without limitation, a Title 11 trustee) shall:

(a)  as the
Non-Debtor Party may elect in a written request, immediately upon such
request:




(i)  perform
all of the obligations provided in this Agreement to be performed by the Debtor
Party including, where applicable and without limitation, providing to the
Non-Debtor Party portions of such intellectual property (including embodiments
thereof) held by the Debtor Party and such successors and assigns or otherwise
available to them; or




(ii)  provide
to the Non-Debtor Party all such intellectual property (including all
embodiments thereof) held by the Debtor Party and such successors and assigns or
otherwise available to them; and




(b)  not
interfere with the rights of the Non-Debtor Party under this Agreement, or any
agreement supplemental hereto, to such intellectual property (including such
embodiments), including any right to obtain such intellectual property (or such
embodiments) from another entity, to the extent provided in Section 365(n) of
Title 11.




10.5.3.  Rights to Intellectual
Property.  If (a) a Title 11 case is commenced by or against
the Debtor Party, (b) this Agreement is rejected as provided in Title 11, and
(c) the Non-Debtor Party elects to retain its rights under this Agreement as
provided in Title 11, then the Debtor Party (in any capacity, including
debtor-in-possession) and its successors and assigns (including, without
limitation, a Title 11 trustee) shall provide to the Non-Debtor Party all such
intellectual property (including all embodiments thereof) held by the Debtor
Party and such successors and assigns, or otherwise available to them,
immediately upon the Non-Debtor Party’s written request.  Whenever the
Debtor Party or any of its successors or assigns provides to the Non-Debtor
Party any of the intellectual property licensed under this Agreement (or any
embodiment thereof) pursuant to this Section 10.5 (Provision for Insolvency),
the Non-Debtor Party shall have the right to perform the obligations of the
Debtor Party under this Agreement with respect to such intellectual property,
but neither such provision nor such performance by the Non-Debtor Party shall
release the Debtor Party from any such obligation or liability for failing to
perform it.  The Parties hereto acknowledge and agree that the
Development Milestone Payments to be paid under Section 6.2 (Development
Milestone Payments) (and any other payment by Ono to Progenics under this
Agreement other than the royalties to be paid under Section 6.4 (Royalty
Payments) and Commercialization Payments to be paid under Section 6.3
(Commercialization Milestone Payments)) do not constitute “royalties” within the
meaning of Title 11 or relate to licenses of intellectual property under this
Agreement.

of access to any intellectual property (including all embodiments thereof) of
the Debtor Party, or any Third Party with whom the Debtor Party contracts to

      AND INSURANCE.

Ono.  Ono will indemnify, defend and hold harmless Progenics,
each of its Affiliates, and each of its and its Affiliates’ employees, officers,
directors and agents (each, a “Progenics Indemnified
Party”) from and against any and all liability, loss, damage, expense
(including reasonable attorneys’ fees and expenses) and cost (collectively, a
“Liability”)
that the Progenics Indemnified Party may be required to pay to one or more Third
Parties resulting from or arising out of: (a) any intentional misconduct or
gross negligence on the part of Ono or its Affiliates in performing any activity
contemplated by this Agreement; (b) personal injury or death of any person as a
result of use of any Product containing the Compound supplied or sold by Ono or
its Affiliates in the Territory; or (c) the material breach by Ono of any of its
representations, warranties or covenants set forth in this Agreement; except, in
each case ((a), (b), and (c)), to the extent caused by the gross negligence or
intentional misconduct of Progenics or any Progenics Indemnified
Party.




11.2.  Indemnification by
Progenics.  Progenics will indemnify, defend and hold harmless
Ono, its Affiliates, distributors and each of its and their respective
employees, officers, directors and agents (each, a “Ono Indemnified
Party”) from and against any and all Liabilities that the Ono Indemnified
Party may be required to pay to one or more Third Parties resulting from or
arising out of: (a) any intentional misconduct or gross negligence on the part
of Progenics or its Affiliates in performing any activity contemplated by this
Agreement; (b) personal injury or death of any person as a result of use of any
Product containing the Compound supplied or sold by Progenics outside the

11.3.  Procedure.  Each
Party will notify the other Party in writing in the event it becomes aware of a
Claim for which indemnification may be sought hereunder.  In case any
proceeding (including any governmental investigation) shall be instituted
involving any Party in respect of which indemnity may be sought pursuant to this
Section 11 (Indemnification and Insurance), such Party (the “Indemnified Party”)
shall promptly notify the other Party (the “Indemnifying Party”)
in writing and the Indemnifying Party and Indemnified Party shall meet to
discuss how to respond to any Claims that are the subject matter of such
proceeding.  The Indemnified Party shall cooperate fully with the
Indemnifying Party in defense of such matter.  The Indemnifying Party,
upon request of the Indemnified Party, shall retain counsel reasonably
satisfactory to the Indemnified Party to represent the Indemnified Party and
shall pay the fees and expenses of such counsel related to such
proceeding.  In any such Claim, the Indemnified Party shall have the
right to retain its own counsel, but the fees and expenses of such counsel shall
be at the expense of the Indemnified Party unless (a) the Indemnifying Party and
the Indemnified Party shall have mutually agreed to the retention of such
counsel or (b) the named parties to any such Claim (including any impleaded
parties) include both the Indemnifying Party and the Indemnified Party and
representation of both Parties by the same counsel would be inappropriate due to
actual or potential differing interests between them.  All such fees
and expenses shall be reimbursed as they are incurred.  The
Indemnifying Party shall not be liable for any settlement of any Claim effected
without its written consent, but, if settled with such consent or if there be a
final judgment for the plaintiff, the Indemnifying Party agrees to indemnify the
Indemnified Party from and against any loss or liability by reason of such
settlement or judgment.  The Indemnifying Party shall not, without the
written consent of the Indemnified Party, effect any settlement of any pending
or threatened Claim in respect of which the Indemnified Party is, or arising out
of the same set of facts could have been, a party and indemnity could have been
sought hereunder by the Indemnified Party, unless such settlement includes an
unconditional release of the Indemnified Party from all liability on Claims that
are the subject matter of such proceeding.

Venue; Service of Process.




13.18.1.  General
Claims.  Except as provided in Section 13.18.2 (Jurisdiction

any Claim between the Parties arising in whole or in part under or in connection
with this Agreement shall be settled by binding arbitration administered by the
American Arbitration Association under its Commercial Arbitration Rules;
provided, however, that the Parties hereby agree that the time schedule for the
appointment of arbitrators and the time schedule for submission of the statement
of defense shall follow the arbitration rules of the International Chamber of
Commerce.  The judgment on the award rendered by the arbitrator may be
entered in any court having jurisdiction thereof.  The arbitration
shall be commenced when one Party serves the other Party with a written demand
to arbitrate.




13.18.2.  Jurisdiction for Actions Related to
Intellectual Property.  Each Party to this Agreement, by its
execution hereof, (a) hereby irrevocably submits to the exclusive jurisdiction
of the state courts of the State of New York located in New York City or the
United States District Court for the Southern District of New York located in
New York City for the purpose of any Claim between the Parties relating to
Patent Rights or Know-How arising in whole or in part under or in connection
with this Agreement, (b) hereby waives to the extent not prohibited by
applicable law, and agrees not to assert, by way of motion, as a defense or
otherwise, in any such Claim, any Claim that it is not subject personally to the
jurisdiction of the above-named courts, that its property is exempt or immune
from attachment or execution, that any such Claim brought in one of the
above-named courts should be dismissed on grounds of forum non conveniens,
should be transferred or removed to any court other than one of the above-named
courts, or should be stayed by reason of the pendency of some other proceeding
in any other court other than one of the above-named courts, or that this
Agreement or the subject matter hereof may not be enforced in or by such court
and (c) hereby agrees not to commence any such Claim other than before one
of the above-named courts.  Notwithstanding the previous sentence, a
Party may commence any Claim in a court other than the above-named courts solely
to seek pre-litigation attachment of assets or preliminary injunction relief
prior to litigation on the merits in the above-named courts or for the purpose
of enforcing an order or judgment issued by one of the above-named
courts.




13.18.3.  Venue.Each Party
agrees that for any Claim between the Parties arising in whole or in part under
or in connection with this Agreement, such Party shall bring such Claims in New
York, New York, United States if either Party requests arbitration under Section
13.18.1 (General Claims) or if a Claim is subject to Section 13.18.2
(Jurisdiction for Actions Related to Intellectual Property).  Each
Party further waives any claim and will not assert that venue should properly
lie in any other location within the selected jurisdiction.

13.18.4.  Service of
Process.  Each Party hereby (i) agrees that service of process
in any Claim between the Parties arising in whole or in part under or in
connection with this Agreement shall constitute good and valid service of
process in any such Claim if sent by registered or certified mail, return
receipt requested, at its address specified pursuant to Section 13.6
(Correspondence and Notices) and (ii) waives and agrees not to assert (by way of
motion, as a defense, or otherwise) in any such Claim any claim that service of
process made in accordance with clause (i) does not constitute good and valid
service of process.




13.19.  Waiver of Jury Trial.TO THE
EXTENT NOT PROHIBITED BY APPLICABLE LAW THAT CANNOT BE WAIVED, THE PARTIES
HEREBY WAIVE, AND COVENANT THAT THEY WILL NOT ASSERT (WHETHER AS PLAINTIFF,
DEFENDANT OR OTHERWISE), ANY RIGHT TO TRIAL BY JURY IN ANY ACTION ARISING IN
WHOLE OR IN PART UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY OF THE
CONTEMPLATED TRANSACTIONS, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND
WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE.  THE PARTIES AGREE
THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN
EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED-FOR AGREEMENT AMONG THE PARTIES
IRREVOCABLY TO WAIVE ITS RIGHT TO TRIAL BY JURY IN ANY PROCEEDING WHATSOEVER
BETWEEN THEM RELATING TO THIS AGREEMENT OR ANY OF THE CONTEMPLATED TRANSACTIONS
WILL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING
WITHOUT A JURY.




13.20.  Dispute Resolution. Except as set forth in
Section 3.1.3 (Decision Making) with respect to tie votes regarding decisions
within the jurisdiction of the various Committees, if the Parties are otherwise
unable to resolve a dispute among them informally, Ono or Progenics, by written
notice to the other, may have such dispute referred to their respective
executive officers designated for attempted resolution by good faith
negotiations (each, a “Responsible
Executive”).




For
Ono:                                           [*]




For
Progenics:                                           [*]

event the Responsible Executives are not able to resolve any such dispute within
[*] days after submission of the dispute to such Responsible Executives, Ono or
Progenics, as the case may be, may pursue whatever measures legally available to
resolve such dispute.  All negotiations pursuant to this Section 13.20
(Dispute Resolution) shall be treated as compromise and settlement
negotiations.  Nothing said or disclosed, nor any document produced,
in the course of such negotiations which is not otherwise independently
discoverable shall be offered or received as evidence or used for impeachment or
for any other purpose in any current or future arbitration or litigation between
the Parties.

13.21.  Specific
Performance.The Parties agree that if any of the provisions
of this Agreement were not performed in accordance with their specific terms, or

law may exist; accordingly the non-defaulting Party, in addition to any other
available rights or remedies, shall have the right to seek, in a court of
competent jurisdiction, specific performance of the terms of this
Agreement.
