the parties hereto agree as follows:





ARTICLE
1.  DEFINITIONS





As used
in this Agreement, the following terms, whether used in the singular or the
plural, shall have the following meanings:


1.1           “Affiliate”
means any corporation or non-corporate business entity, which controls, is
controlled by, or is under common control with a party to this
Agreement.  A corporation or non-corporate business entity shall be
regarded as in control of another corporation if it owns or directly or
indirectly controls at least fifty-one percent (51%) of the voting stock of the
other corporation, or (i) in the absence of the ownership of at least fifty-one
percent (51%) of the voting stock of a corporation, or (ii) in the case of a
non-corporate business entity, if it possesses, directly or indirectly, the
power to direct or cause the direction of the management and policies of the
corporation or non-corporate business entity, as applicable. Notwithstanding the
foregoing, the Government of Japan and other entities controlled by the
Government of Japan (other than through Japan Tobacco Inc.) are not considered
Affiliates of Sublicensee.


1.2           “Combination
Product” means a Product containing one or more therapeutically active
ingredients in addition to the Compound.


1.3           “Compound”
means ferric citrate:  FeC6H5O7 • xH2O.


1.4            Intentionally
omitted.


1.5            Intentionally
omitted.


2





1.6           “Follow-on
Product” means products, other than the Product, which contain ferric
ion as an active pharmaceutical ingredient for use, either alone, or in
combination with one or more therapeutically active ingredients.


1.7            “Improvements”
means any and all improvements, materials, technical data and information
whether patented or unpatented, including but not limited to any changes to, or
new therapeutic applications for, the Compound, the Product or in the
Sublicensor Know-How or Sublicensee Know-How including, but not limited to any
analogues, or derivatives of the Compound, and changes in the manufacturing
process for the Compound or the Product which are conceived or reduced to
practice during the term of this Agreement.


1.8           “Indication”
means any therapeutic application for a Product that is covered by the Patent
Rights.


1.9           “Initiation”
means the administration of the first dose to the first patient in a clinical
trial.


1.10         “Net
Sales” with respect to any Product means the gross sales (i.e. gross invoice
prices) of such Product billed by Sublicensee and its sublicensees, if any, to
Third Party customers on all sales of a Product, and exclusive of inter-company
transfer or sales, less the reasonable and customary deductions from such gross
sales, including:


(a)  actual
credited allowances to such Third Party customers for spoiled, damaged, outdated
and returned Product and for retroactive price reductions,


(b)  the
amounts of trade, cash discounts and rebates, to the extent such discounts and
rebates were not deducted by Sublicensee at the time of invoice in order to
arrive at the gross invoice prices,


(c)  all
transportation, handling charges and freight insurance, sales taxes, excise
taxes, use taxes or import/export duties paid, and


(d)  all
other reasonable and customary allowances and adjustments actually credited to
customers whether during the specific royalty period or not.


In the
event that the Product(s) is sold as part of a Combination Product, the Net
Sales of the Product(s), for the purposes of determining royalty payments, shall
be determined by multiplying the Net Sales of Combination Product (as defined in
the standard Net Sales definition) by the fraction, A / (A+B) where A is the
weighted average sale price of the Product(s) when sold separately in finished
form (as defined below), and B is the weighted average sale price of the other
product(s) sold in the Sublicense Territory separately in finished
form.


3





In the
event that the weighted average sale price of the Product(s) can be determined
but the weighted average sale price of the other product(s) in the Sublicense
Territory cannot be determined, Net Sales for purposes of determining royalty
payments shall be calculated by multiplying the Net Sales of the Combination
Product by the fraction A / C where A is the weighted average sale price of the
Product(s) when sold separately in finished form and C is the weighted average
selling price of the Combination Product.


In the
event that the weighted average sale price of the other product(s) in the
Sublicense Territory can be determined but the weighted average sale price of
the Product cannot be determined, Net Sales for purposes of determining royalty
payments shall be calculated by multiplying the Net Sales of the Combination
Product by the following formula:  1 – (B/C)  where B is the
weighted average sale price of the other product(s) when sold separately in
finished form and C is the weighted average selling price of the
Combination Product.


In the
event that the weighted sale price of both the Product(s) and the other
product(s) in the Combination Product in the Sublicense Territory cannot be
determined, the Parties will attempt to agree on an appropriate weighted average
sale price of both the Product(s) and the other product(s) in the Combination
Product, and lacking such agreement the Net Sales of the Product(s) shall be
deemed equal to fifty percent (50%) of the Net Sales of the Combination
Product.


By way of
example, the parties assume a Combination product “C” consisting of the Product
“A” and the other product “B.”  When the weighted average sale prices
in the Sublicense Territory of A, B and C are 50, 40 and 90, respectively, the
parties agree that the fraction to be used for Net Sales calculation for
determining royalty payments shall become as follows:





i)
            in
      case the “50” and “40” are known, 50/(50+40), i.e.,
  5/9;


ii)
            in
      case the “40” is unknown but “90” is known, 50/90, i.e.,
    5/9;


iii)
            in
      case the “50” is unknown but “90” is known, 1-40/90, i.e., 5/9;
      and


4





iv)
            in
      case none of those is known, 1/2 unless otherwise agreed between the
      parties.


The
weighted average sale price for a Product, other product(s), or Combination
Product shall be calculated once each calendar year and such price shall be used
during all applicable royalty reporting periods for the entire calendar
year.  When determining the weighted average sale price of a Product,
other product(s), or Combination Product, the weighted average sale price shall
be calculated by dividing the sales dollars (translated into U.S. Dollars) by
the daily dose units of active ingredient sold during the twelve (12) months (or
the number of months sold in a partial calendar year) for the respective
Product(s), other product(s), or Combination Product.  In the initial
calendar year, a forecasted weighted average sale price will be used for
Product(s), other product(s), or Combination Product.  Any over or
under payment due to a difference between forecasted and actual weighted average
sale prices will be paid or credited in the first royalty payment of the
following calendar year.


The
Parties acknowledge that the foregoing determination for Net Sales of
Combination Products may not be the same as the determination for Net Sales of
Combination Products to be agreed upon between Sublicensor and Panion in
accordance with the Panion License Agreement.  Sublicensor agrees to
use its commercially reasonable efforts to obtain Panion’s agreement to adopt
the terms of this Section 1.10 to calculate Net Sales of Combination Products
and will keep Sublicensee informed of ongoing negotiations concerning
the provisions for Combination Products with Panion.  In the event
Sublicensor and Panion agree upon a different determination, Sublicensor shall
immediately seek Sublicensee’s consent to amend this Section 1.10 to match such
determination, which consent shall not be unreasonably withheld or delayed.


The sale
of a Product solely for the research or clinical testing of such Product shall
be excluded from the computation of Net Sales of such Product, provided that
Sublicensee’s sale of the Product was at cost, and such Product was used for
research or clinical testing.

3.1           Grant. Subject to the
terms and conditions of this Agreement, Sublicensor hereby grants to Sublicensee
an exclusive sublicense, with the right to further sublicense to its Affiliates,
to develop, have developed, make, have made, use, have used, offer to sell,
sell, have sold, and import and export the Product or the Compound in the
Sublicense Territory and to make, manufacture, have made and have manufactured

Sublicensee shall be entitled to sublicense to Third Parties the right to
manufacture the Product or the Compound, provided such Third Party manufacturers
are permitted to sell only to Sublicensee or their Affiliates.  Except

further sublicenses under this Agreement without the written consent of
Sublicensor, which consent shall not be unreasonably withheld or
delayed.  For the avoidance of doubt, Sublicensor and Sublicensee
agree that this Section does not apply to Third Party distributors and that
Sublicensee may contract with Third Party distributors without the written
consent of Sublicensor.


10


3.3           Retained
Rights.  The grant of licenses under Section 3.1 shall not
preclude Sublicensor from utilizing the Patent Rights and Sublicensor Know-How,
and any Improvements related thereto, for the purpose of carrying out
development and commercialization activities relating to the Product in
connection with Sublicensor’s rights outside of the Sublicense Territory,
provided, however, that Sublicensor shall not sell and shall cause its
Affiliates and its sublicensees not to sell Compound or Product to customers
outside the Sublicense Territory which Sublicensor, its Affiliate or its
sublicensee knows, or has reason to know, plan to resell for use in the

clinical trials of the Compound or Product in the Sublicense Territory except
upon the prior written consent of Sublicensee.


3.4           Sublicense
Territory.  Other than as permitted by this Article 3,
Sublicensee shall not develop, manufacture, sell, use, offer for sale or import

written consent of Sublicensor, which Sublicensor may grant or withhold in its
sole discretion.  Sublicensee shall not sell and shall cause its
Affiliates and its sublicensees not to sell Compound or Product to customers in
the Sublicense Territory which Sublicensee, its Affiliate or its sublicensee
knows, or has reason to know, plan to resell for use outside the Sublicense

Protection.  Nothing in this Agreement precludes Sublicensee
from developing, manufacturing, selling, using, offering for sale or importing
Product in territories where Patent Rights do not exist or have already expired
in their entirety.   Notwithstanding the foregoing, Sublicensee
shall not be entitled to use Proprietary Information solely owned by Sublicensor
outside of the Sublicense Territory other than to make, manufacture, have made
or have manufactured the Product outside the Sublicense Territory for sale
within the Sublicense Territory.


3.6           Joint Steering
Committee.  To coordinate the activities under this Agreement,

non-clinical and toxicology programs to maximize the potential for use in
multiple territories, (b) periodic updates on the status of the clinical
development program and sharing of pharmacovigilance information, (c) review of

and Sublicensee shall each appoint one of its members as a JSC co-chair (“JSC
Co-Chair”).  Sublicensor’s JSC Co-Chair shall be chairperson of all
the JSC meetings.  The JSC Co-Chairs shall be jointly responsible for
preparing the meeting agenda, and Sublicensor’s JSC Co-Chair shall be
responsible for preparing the first draft of the minutes from such
meeting.  JSC meeting minutes shall be distributed in draft form to
the members of the JSC not later than thirty (30) days following each JSC
meeting, and shall be deemed accepted and effective unless the other party’s JSC
Co-Chair has objected to the same in writing within thirty (30) days of its
receipt of such minutes.  Final minutes of each JSC meeting shall be
promptly distributed to the parties. Each party shall bear its own personnel and
travel costs and expenses relating to JSC meetings.


As of the
Effective Date, the parties agree that participation on, and any duties
associated with, the JSC shall be voluntary, and no penalty under this Agreement
shall apply for non-participation.


3.7           Joint Development
Team.  The parties will form a Joint Development Team (the
“JDT”).  The JDT will meet on a schedule to be determined by the
parties but not less than twice yearly and will be responsible for facilitating
the exchange of preclinical data, clinical data, information, materials and
results between Sublicensor and Sublicensee and for consulting on the regulatory
development of Product in the Sublicense Territory, including regulatory filings
relating to manufacture of Product for the Sublicense Territory and consultation
as to changes in specifications or other changes for Product in the Sublicense
Territory.


As of the
Effective Date, the parties agree that participation on, and any duties
associated with, the JDT shall be voluntary, and no penalty under this Agreement
shall apply for non-participation.


3.8           Alliance
Managers.  Each party shall designate one (1) alliance manager
(the “Alliance Manager”).  One of the JSC Co-Chairs or JDT Co-Chairs
may also serve as the Alliance Manager of the party.  The Alliance
Managers will manage and oversee operational activities in connection with this
Agreement, and will serve as the contact persons concerning on-going operations
under this Agreement.  The Alliance Managers shall promote effective
communication between the parties and coordination of the parties’

Dispute Resolution.  Sublicensee shall be solely responsible
for making final decisions arising out of the JSC, JDT or such other
committee(s) as may be established (“Other
Committee(s)”).  Notwithstanding the foregoing, in the event that
Sublicensor has a commercially reasonable belief that action to be taken by
Sublicensee is reasonably likely to have a material adverse impact on its
activities, or the activities of its sublicensees, outside the Sublicense
Territory, Sublicensor shall notify Sublicensee of such belief.  In
case Sublicensee disagrees with such belief by Sublicensor, and the JSC, JDT or
Other Committee fails to reach unanimous agreement on such a matter and that
disagreement cannot be resolved within a period of fifteen (15) business days
following the meeting of the JSC, JDT or Other Committee, the matter shall be
referred to the Chief Executive Officer of Keryx and to the President of the JT
Pharmaceutical Division for discussion and, if not resolved in such manner,
shall be subject to Arbitration pursuant to Article 19.

ARTICLE
5.  ROYALTIES





5.1           Royalties.  In
consideration of the sublicense rights granted to Sublicensee hereunder, for
each Product where the manufacture, use or sale of such Product would but for
the license granted hereunder, infringe a Valid Claim, Sublicensee shall pay to
Sublicensor a royalty on their respective Net Sales, as follows:


(a)  a
royalty of ****** of annual Net Sales equal to or less ******;


(b)  a
royalty of ****** of annual Net Sales between ******;


(c)  a
royalty of ****** of annual Net Sales in excess of ******.


For
purposes of this Section 5.1, royalties shall be calculated based on total Net
Sales in any given calendar year.  By way of example, if in a given
calendar year Net Sales were forty (40) billion Japanese Yen, then the amount of
royalty owed for that year would be ****** (calculated as the sum of ****** x
****** plus ****** x ****** plus ****** x ******).  Notwithstanding
the foregoing, in the event (i) the Panion License Agreement expires before the
termination or expiration of this Agreement and Sublicensor is no longer
required to pay royalties to Panion under the Panion License Agreement, the
applicable royalty percentage to be paid by Sublicensee to Sublicensor under
clauses (a), (b) and (c) of this Section 5.1 shall be reduced to ******, ******
and ******, respectively, or (ii) subject to Section 16.3, the Panion License
Agreement is terminated before the termination or expiration of this Agreement,
the royalties and other amounts to be paid by Sublicensee to Sublicensor shall
be reduced by all royalties and other amounts payable directly by
Sublicensee to Panion.


5.2           Accrual of
Royalties.   No royalty shall be payable on a Product
made, sold, or used for research or clinical testing purposes or distributed as
samples, provided such samples are sold by Sublicensee at cost.  No
multiple royalty shall be payable because the manufacture, use, or sale of a
Product is covered by more than one Valid Claim.

******
Confidential material redacted and filed separately with the
Commission.


5.3          Royalty Withheld due to
Invalid Claims.  In the event that all applicable claims of a
patent included within the Patent Rights under which Sublicensee is paying a
royalty according to Section 5.1 shall be held invalid or unenforceable by a
court of competent jurisdiction in the Sublicense Territory, Sublicensee may
withhold payments of royalties which would otherwise have been due on Net Sales
in the Sublicense Territory by reason of Sections 4.3 and 5.1 until such
judgment shall be finally reviewed by an unappealed or unappealable decree of a
higher court of competent jurisdiction in the Sublicense
Territory.  The Sublicensee shall promptly repay Sublicensor any
withheld royalty payments upon a final adjudication that the applicable claims
of a patent included within the Patent Rights under which Sublicensee is paying
a royalty under Section 5.1 are valid and enforceable.   For
clarification, the aforementioned withheld royalty shall not bear any interest
thereon.


5.4           Compulsory Licenses.
If Sublicensee is caused to grant a compulsory license to any Third Party with
respect to a Product in the Sublicense Territory, then the royalty rate to be
paid by Sublicensee on Net Sales due on such Product in that country under
Section 5.1 shall be reduced to the rate paid by such Third Party compulsory
Sublicensee on such Product.


5.5           Third Party
Royalties.  Sublicensor shall be responsible for payment of
Third Party royalties owed on sales of Product in the Sublicense Territory
with respect to any issued patent or patent application that has been published
by the applicable patent office anywhere in the world prior to and including the
date that is two (2) years after September 26, 2007 that are required to secure
Freedom to Operate in the Sublicense Territory.  For the purposes of
this Agreement, “Freedom to Operate” shall mean such valid patents that, but for
a license, would be infringed by the development, manufacture, use or sale of a
Product for the Indication.  With respect to patents or patent
applications that are published by the applicable patent office anywhere in the
world more than two (2) years after September 26, 2007 that are required to
secure Freedom to Operate in the Sublicense Territory, then (a) if a license to
such patent is limited to the Sublicense Territory, then Sublicensor and
Sublicensee shall each be responsible for ****** of such license fees and
royalty obligations; and (b) if a license to such patent includes countries
outside the Sublicense Territory, then Sublicensor shall be responsible for
****** of such license fees and royalty obligations and Sublicensee shall be
responsible for ****** of such license fees and royalty
obligations.  Notwithstanding the foregoing, Sublicensor’s obligation
to pay Third Party royalties, including, without limitation, royalties owed to
Panion, shall not exceed the sales milestone payments and royalties to which
Sublicensor is entitled under Sections 4.3 and 5.1 of this
Agreement




16




5.6          WithholdingTax.  If
any payment due to Sublicensor hereunder is subject to withholding taxes or
similar governmental charge (“Withholding Tax”) required to be paid or withheld
thereon by applicable law in Japan, then Sublicensee shall deduct such
Withholding Tax from such payment due Sublicensor hereunder at a rate not to
exceed the then-prevailing rate provided for in applicable provisions of the
Conventions between the Governments of the United States and Japan for the
Avoidance of Double Taxation and the Evasion of Taxes (the
“Convention”).  Sublicensee shall provide Sublicensor, as soon as
possible, a certificate evidencing withholding or payment of any such
Withholding Tax by Sublicensee, its Affiliates or its sublicensees for the
benefit of Sublicensor.  The parties understand as of September 26,
2007 that under the provisions of the current Convention, payments to
Sublicensor under this Agreement are not subject to withholding, provided that
Sublicensor provide Sublicensee with appropriate certificates of residency as
required by Japanese law.

Dollars, which shall have accrued hereunder in respect of such sales with a
summary computation of such royalties; (c) withholding taxes, if any required by
law to be deducted in respect of such sales; and (d) the exchange rates used in
determining the amount of United States Dollars payable.  Royalty
reports shall be submitted to Sublicensor within forty-five (45) days after the
close of each Reporting Period. Net Sales and royalties payable shall be
expressed in both Japanese Yen and the United States Dollars equivalent,
calculated using the simple average of the exchange rate published in the Wall

Sublicensee shall furnish to Sublicensor appropriate evidence of payment of, and
itemize any tax, credits or specific amount deducted from any royalty
payment.

Records.  Royalty payments shall be made by wire transfer in
United States currency to a designated bank account of Sublicensor in the United
States and shall be due forty-five (45) days after the close of each Reporting
Period.  Payment of royalties in whole or in part may be made in
advance of such due date.  In case no royalty is due for any given
Reporting Period, Sublicensee shall so report to
Sublicensor.  Sublicensee shall keep accurate records for a period of
at least three (3) years in sufficient detail to enable the royalty payable
hereunder to be determined and confirmed.


6.3           Right to
Audit.  Upon written request of Sublicensor, but not more
thanonce in each
calendar year, Sublicensee shall permit an independent public accountant,
selected by Sublicensor or Panion and acceptable to Sublicensee, which
acceptance shall not be unreasonably withheld, to have access during normal
business hours to those records of Sublicensee as may be reasonably necessary to
verify the accuracy of the royalty reports hereunder in respect of any calendar
year ending not more than thirty-six (36) months prior to the date of such
request.  The report prepared by such independent public accountant, a
copy of which promptly shall be provided to Sublicensee, shall disclose only the
amount of any underpayment or overpayment of royalties, if any, without
disclosure of or reference to supporting documentation.  If such
independent accountant’s report shows any underpayment of royalties, Sublicensee
shall remit to Sublicensor the amount of such underpayment within thirty (30)
days after Sublicensee’s receipt of such report, and if such underpayment
exceeds five percent (5%) of the royalty due, Sublicensee shall reimburse
Sublicensor for its reasonable out-of-pocket expenses for the audit, upon
submission of supporting documentation.  Any overpayment of royalties
shall be creditable against future royalties payable in subsequent royalty
periods, allocated evenly over the next-following two (2) royalty
periods.  In the event this Agreement is terminated or expires before
such overpayment is fully credited, Sublicensor shall pay Sublicensee the
portion of such overpayment not credited within one hundred twenty (120) days
after the date of such termination or expiration.


6.4           Confidentiality of

review under Section 6.3 shall be deemed the Proprietary Information of
Sublicensee.

Sublicensee pursuant to this Agreement shall, if overdue, bear interest at the
rate equal to two percent (2%) over the prime rate as quoted by Citibank NA and
not to exceed ten percent (10%) per annum until paid.  The payment of
such interest shall not preclude Sublicensor from exercising any other rights it
may have because any payment is overdue.

which consent shall not be unreasonably withheld or delayed, and provide to
Sublicensor in a timely manner i) summaries of meetings held with Panion, Dr.
Hsu or GloboAsia, as the case may be, without the presence of Sublicensor’s
employees or representatives, and ii) copies of relevant
documents exchanged with Panion, Dr. Hsu or GloboAsia, as the case may
be, without being copied to Sublicensor.  Sublicensor shall
obtain from Panion, Dr. Hsu and GloboAsia the authority in the Sublicense
Territory for Sublicensee to prosecute or to cause the prosecution of the patent
applications that are enumerated in Exhibit 1 of this Agreement, to obtain
patents thereon and to maintain patents, including any correction trials and
invalidation trials,  included in the Patent Rights in effect during

shall not be unreasonably withheld or delayed by
Sublicensor.  Sublicensee shall be solely responsible for said
prosecution of the patent applications that are enumerated in Exhibit 1 of this
Agreement, to obtain patents thereon and to maintain patents, including any

Sublicensee’s right as a primary licensee in the Sublicense Territory until said
registration of “Senyo
Jisshiken.”  Sublicensee shall keep Sublicensor advised of the
status of all patent applications and patents relating to the Patent Rights by
providing Sublicensor with copies of such patent applications and patents and
copies of all patent office correspondence relating thereto including any office

license rights and its obligations under this Agreement, with respect to such
patent applications and patents in the Sublicense Territory shall terminate,
without affecting its license rights and other obligations to pay with respect
to any other patent applications or patents included in the Patent
Rights.  After the Effective Date of this Agreement, in the event
Exhibit 1 of the Panion License Agreement is amended to add additional patents
related to the Compound (“Additional Patents”), the parties shall amend Exhibit

Sublicensee shall own all right, title and interest in and to Improvements
invented solely by Sublicensee’s employees or contractors and Sublicensor shall
own all right, title and interest in and to Improvements invented solely by
Sublicensor’s employees or contractors.  Patent applications and

Agreement, i) in the Sublicense Territory, to such extent as granted to
Sublicensee under Section 3.1 Sublicensee shall have the liberty to freely
practice Improvements, or license to any third party in connection with a
sublicense to sell Products, provided that such sublicensees agree to share any
Improvements with Sublicensor and Sublicensee, and ii) outside the Sublicense
Territory, the Sublicensor shall have the liberty to freely practice
Improvements, or license to any third party in connection with a sublicense to
sell Products, provided that such sublicensees agree to share any Improvements
with Sublicensor and Sublicensee.  In the event of a termination of

absence of a breach by Sublicensor, then Sublicensor’s rights under this Section
8.2 related to Improvements shall survive but Sublicensee’s rights shall be
terminated and Sublicensor shall have a perpetual, exclusive, royalty-free,
sublicensable license for the purpose of commercialization of Product to
any patented Improvements solely or jointly invented by
Sublicensee.  If this Agreement is terminated by Sublicensee for
breach by Sublicensor, then Sublicensor may continue to have the rights set
forth herein to non-patented Improvements outside the Sublicense
Territory without any consideration therefor and shall have the option
to acquire a license for the use outside the Sublicense Territory of patented
Improvements that were solely invented by Sublicensee at a royalty rate of
****** of net sales of the relevant products which, but for the license, would
infringe a valid patent owned by Sublicensee.  Upon expiration of this
Agreement, Sublicensor may continue to have the rights set forth herein to
non-patented and jointly-invented Improvements outside the Sublicense
Territory without any consideration therefor and shall have the option
to acquire an exclusive, except as to Sublicensee, license for the use outside
the Sublicense Territory of patented Improvements which were solely
invented by Sublicensee at a royalty rate of ****** of net sales of the relevant
products which, but for the license, would infringe a valid patent owned by
Sublicensee.   The formula for calculating net sales for
Sublicensor’s products under this Section 8.2(a) shall be consistent with the
provisions of Section 1.10 of this Agreement.

(b)           During
the term of this Agreement, for patent applications and patents relating to
Improvements invented solely by Sublicensor, the provisions of Section 8.1 shall
apply.




(c)           Following
expiration or termination of this Agreement, Sublicensor shall be solely
responsible, at its sole discretion and expense, for preparing, filing,
prosecuting and maintaining in such countries where it deems appropriate, patent
applications and patents relating to Improvements invented solely by Sublicensor
and for conducting interference, re-examination, reissue and opposition
proceedings relating to such patent applications and patents.




(d)           During
the term of this Agreement, Sublicensee shall be responsible, in its sole
discretion, for preparing, filing, prosecuting and maintaining in the Sublicense
Territory, patent applications and patents relating to Improvements invented
solely by Sublicensee or jointly by Sublicensee and Sublicensor.  In
case of Improvements invented jointly by Sublicensee and Sublicensor, the costs
necessary for preparation, filing, prosecution and maintenance of the
Improvements shall be equally borne by Sublicensor and
Sublicensee.  Notwithstanding the foregoing, if Sublicensee elects
(after consultation with Sublicensor) not to prosecute, or to discontinue the
prosecution of any patent applications concerning joint Improvements, or to
discontinue the maintenance of any patents or patent applications concerning
joint Improvements, then (i) Sublicensor shall have the right to assume the full
responsibility for the prosecution of such patent applications or the
maintenance of such patents and patent applications at its own cost and expense,
(ii) Sublicensee shall assign its interest in such patents and patent
applications to Sublicensor, and (iii) such patents and patent applications
shall no longer be subject to this Agreement.

(e)           Following
expiration or termination of this Agreement, Sublicensee shall be solely
responsible, in its sole discretion and expense, for preparing, filing,
prosecuting and maintaining in such countries where it deems appropriate, patent
applications and patents relating to Improvements invented solely by Sublicensee
and for conducting interference, re-examination, reissue and opposition
proceedings relating to such patent applications and patents.




(f)           Following
expiration or termination of this Agreement, the parties shall be jointly
responsible for preparing, filing, prosecuting and maintaining in such countries
where the parties jointly agree, patent applications and patents relating to
Improvements jointly invented by the parties and for conducting interference,
re-examination, reissue and opposition proceedings relating to such patent
applications and patents. The parties shall jointly bear all costs relating

9.  INFRINGEMENT





9.1           Infringement by a Third
Party.  In the event that either party becomes aware that a Compound
or a Product being made, used or sold by a Third Party infringes the Patent
Rights licensed hereunder, such party shall promptly advise the other party of
all known facts and circumstances relating thereto. To the extent of their
respective ability under Japanese law, Panion (on behalf of itself and Dr. Hsu)
and Sublicensor shall have the first and second right, respectively, to enforce
at its sole expense the Patent Rights licensed under this Agreement against
infringement by Third Parties.  Sublicensee shall reasonably cooperate
in any such enforcement and, if necessary, join as a party therein, at the
expense of Sublicensor.  Sublicensor shall have the right to retain
****** of the proceeds of any such enforcement
action.   Notwithstanding the foregoing, Sublicensee shall have
the right to enforce against infringement by Third Parties of the Patent Rights
licensed hereunder, in the event that neither Panion (on behalf of itself and
Dr. Hsu) nor Sublicensor exercise its right.  Sublicensor shall make
all necessary arrangements with Panion, Dr. Hsu and GloboAsia for Sublicensee to
take actions against infringement by Third Parties of the Patent Rights licensed
hereunder.





9.2           Infringement by
Sublicensee.   In the event that it is determined by any
court of competent jurisdiction that the import, manufacture, use or sale of any
Product or Compound by Sublicensee or its sublicensees in accordance with the
terms and conditions of this Agreement infringes, or Sublicensee and Sublicensor
reasonably determine and agree that the import, manufacture, use or sale of such
Product or Compound is likely to infringe, a Third Party patent or related
intellectual property right in the Sublicense Territory, Sublicensee shall in
consultation with Sublicensor use its reasonable best efforts to: (i) procure at
Sublicensor’s expense a license from such Third Party
authorizing Sublicensee to continue to import, manufacture, use or sell
such Product or Compound; or (ii) modify such Product or Compound or its
manufacture so as to render it non-infringing.




27




9.3          In
the event that neither of the foregoing alternatives is reasonably available or
commercially feasible, Sublicensee may at its option (i) either cease the
import, manufacture, use and sale of such Product or Compound for so long as and
to the extent that such activities are infringing the relevant Third Party
patents, in which case the obligation of Sublicensee hereunder to pay royalties
shall also cease, or (ii) terminate the rights and licenses granted in the
Sublicense Territory in which the infringement of Third Party patents has
occurred or is likely to occur, in which case the obligation of Sublicensee
hereunder to pay royalties shall also terminate in the Sublicense
Territory.  With regard to damages caused to Sublicensee by a Third
Party patent or related intellectual property right for which Sublicensor would
otherwise have been solely responsible for payment of royalties under Section
5.5, Section 14.2 will apply.

15.1        Treatment of Proprietary
Information.  Except as otherwise provided in this Article 15,
during the term of this Agreement and for a period of five (5) years following
expiration or termination thereof, a party (the “Receiving Party”) will retain
in confidence and use only for purposes of this Agreement Proprietary
Information supplied by or on behalf of the other party (the “Disclosing
Party”).  For purposes of this Article 15, all such Proprietary
Information which a Receiving Party is obligated to retain in confidence shall
be disclosed in written form and marked “Confidential” or with similar
designation, or if originally disclosed visually or orally, reduced to such
written form within thirty (30) days of such original disclosure.


15.2        Right to
Disclose.  To the extent it is reasonably necessary or
appropriate to fulfill its obligations or exercise its rights under this
Agreement or any rights which survive termination or expiration hereof, a
Receiving Party may disclose Proprietary Information to its Affiliates,
Sublicensees, consultants, agents, outside contractors and clinical
investigators (collectively the “Representatives”) on condition that such
Representatives agree (i) to keep the Proprietary Information confidential for
at
least the same time periods and to the same extent as such party is required to
keep the Proprietary Information confidential and (ii) to use the Proprietary
Information only for such purposes as the Receiving Party is entitled to use the
Proprietary Information.  Each party warrants that each of its
Representatives to whom any Proprietary Information is disclosed shall
previously have been informed of the confidential nature of the Proprietary
Information and shall have agreed to be bound by the terms and conditions of
confidentiality as set forth in this Agreement.  The Receiving Party
shall ensure that the Proprietary Information provided by the Disclosing
Party shall not be used or disclosed by such Representatives except as permitted
by this Agreement.  The Receiving Party shall stand responsible for
any breach by its Representatives of the confidentiality provisions set forth in
this Agreement.


15.3        Release From
Restrictions.  The obligation not to disclose Proprietary
Information shall not apply to any part of such Proprietary Information
which:


(i) is or
becomes patented, published or otherwise part of the public domain other than by
the unauthorized acts of the Receiving Party or its Affiliates or Sublicensees
in contravention of this Agreement; or


(ii) is
disclosed to the Receiving Party by a Third Party which did not obtain such
Proprietary Information directly or indirectly from the Disclosing Party;
or


41





(iii)
prior to disclosure under this Agreement, was already in the possession of the
Receiving Party as evidenced by its written records, provided such Proprietary
Information was not obtained, directly or indirectly, from the Disclosing Party;
or


(iv) is
developed by the Receiving Party independent of Proprietary Information received
from the Disclosing Party as evidenced by its written records.




15.4        Public
Domain.  For the purpose of this Agreement, specific
information disclosed as part of the Proprietary Information shall not be deemed
to be in the public domain or in the prior possession of the Receiving Party
merely because it is embraced by more general information in the public domain
or by more general information in the prior possession of the Receiving
Party.




15.5        Ownership of Proprietary
Information. Except as otherwise agreed to hereunder, all Proprietary
Information disclosed by the Disclosing Party shall remain the property of the
Disclosing Party.  In cases where return of Proprietary Information is
requested according to Article 16 hereunder, upon the written request of the
Disclosing Party (i) all tangible Proprietary Information provided by the
Disclosing Party (including, but not limited to all copies thereof) except for
Proprietary Information consisting of analyses, studies and other documents
prepared by or for the benefit of the Receiving Party shall be promptly returned
to the Disclosing Party, and (ii) all portions of such analyses, studies and
other documents not prepared by or for the benefit of the Receiving Party
(including all copies thereof and all unused samples of materials provided by
the Disclosing Party) which are within the definition of Proprietary Information
shall be destroyed, and the Receiving Party shall certify such destruction in
writing to the Disclosing Party.  Notwithstanding the foregoing, the
Receiving Party may retain one copy of the Proprietary Information of the
Disclosing Party in its legal department for the sole purpose of determining its
obligations hereunder.


42


15.6    
    Legal Disclosure. The
Receiving Party may disclose the Proprietary Information of the Disclosing Party
to the extent reasonably necessary in prosecuting or defending litigation,
complying with applicable laws, governmental regulations or court order, or
otherwise submitting required information to tax or other governmental
authorities.  If the Receiving Party intends to so disclose any such
Proprietary Information, the Receiving Party shall provide the Disclosing Party
prompt prior notice of such fact so that the Disclosing Party may seek to obtain
a protective order or other appropriate remedy concerning any disclosure of such
Proprietary Information.  The Receiving Party will reasonably
cooperate with the Disclosing Party in connection with the Disclosing Party’s
efforts to obtain any such order or other remedy.  If any such order
or other remedy does not fully preclude the disclosure of such Proprietary
Information, the Receiving Party will make such disclosure only to the extent
that such disclosure is legally required and will use its reasonable efforts to
have confidential treatment accorded to the disclosed Proprietary
Information.




15.7        
No
Title.  Except as otherwise expressly set forth in this
Agreement, nothing herein shall be construed as giving the Receiving Party any
right, title and interest in and to the Proprietary Information of the
Disclosing Party.

Permitted
Disclosures.

Party.

      Territory;


(ii)
            upon
      expiration or termination by either party for any reason, the rights and
      obligations under Articles 2, 6, 10, 14, 15, 16, 19 and 26 and the
      applicable provisions of Section 8.
2;


(iii)
            expiration
      or termination of this Agreement shall not relieve either party of any
      obligations which accrued to that party prior to such expiration or
      termination for any reason;


(iv)
            any
      cause of action or remedy for breach shall survive the expiration or
      termination of this Agreement.

      Sublicensee.


16.2.1     Termination Without
Cause.  Sublicensee may terminate this Agreement without cause
at any time upon at least sixty (60) days prior written notice to Sublicensor if

written notice to Sublicensor if termination occurs following receipt of
marketing authorization for the Product in the Sublicense
Territory.


16.2.2     Termination for
Breach.  Sublicensee may terminate this Agreement upon or after

16.2.3     Termination for
Insolvency.  Sublicensee may terminate this Agreement in its

amalgamation.


16.3         Termination by
Sublicensor.   Sublicensor may terminate this Agreement in
its entirety for cause at any time upon at least sixty (60) days prior written
notice to Sublicensee upon the occurrence of any of the following:

if such breach is not cured within such sixty (60) day period; or


(b) upon
or after the bankruptcy, insolvency, dissolution or winding up of Sublicensee
other than for the purpose of reconstruction or amalgamation.


For the
avoidance of doubt, a failure to make a payment otherwise owed under Article 4
or Article 5 that remains uncured for at least sixty (60) days following written
notice shall be deemed a material breach.  Furthermore, Sublicensor
agrees that it will not voluntarily terminate the Panion License Agreement (or
allow such agreement to be terminated by Panion), unless Sublicensor maintains
its license for the Sublicense Territory on terms and conditions no less
favorable to Sublicensee as in this Agreement or makes arrangements for

and Sublicensee Know-How in connection with Sublicensor’s effort to market
Products in the Sublicense Territory or to license to such Third Party the right
to manufacture and sell a Product in the Sublicense Territory.

within six (6) months thereafter, subject to fulfillment of the royalty
obligations relating thereto.


16.6        Change of

Bankruptcy.  All rights and licenses granted under or pursuant
to this Agreement by Sublicensor are, and shall otherwise be deemed to be, for
purposes of Section 365(n) of the U.S. Bankruptcy Code, licenses of rights to

Code.  The Parties agree that Sublicensee, as sublicensee of such
rights under this Agreement, shall retain and may fully exercise all of its
rights and elections under the U.S. Bankruptcy Code.  The Parties
further agree that, in the event of the commencement of a bankruptcy proceeding
by or against Sublicensor under the U.S. Bankruptcy Code that is not dismissed
within sixty (60) days of the first date of filing, Sublicensor hereby grants to
Sublicensee, subject to Sublicensee’s obligations under Section 365(n), a right
of access and to obtain possession of and to benefit from each of the following
embodiments to the extent related to Sublicensee’s exercise of its license
rights to the Compounds and Products in the Sublicense Territory in accordance

if not delivered under clause (a), following the rejection of this Agreement by
Sublicensor upon Sublicensee’s reasonable written request
therefor.  Recognizing that the embodiments described above may be
useful or necessary to Sublicensor in connection with its continued operation of
its business, and that a Third Party may also have a right of access to such
embodiment under Section 365(n) of the Bankruptcy Code or applicable
non-bankruptcy law, where there is a fixed or limited quantity of any tangible
item of such embodiment described above, Sublicensee shall be entitled to a pro
rata portion thereof.
