royalties within sixty (60) days after the end of each such calendar quarter.
Such royalties shall be calculated on the basis of Net Revenue in the local
currency of each country, and converted into U.S. Dollars and paid in U.S.
Dollars on the basis of the average currency exchange rate for the applicable
calendar quarter quoted by Tokyo Mitsubishi Bank (or its successor) for currency
exchange in excess of one million U.S. dollars ($1,000,000).

5.5 Manner of Payment. Remittance of payments under this Article 5 will
be made by means of wire or electronic transfer to the receiving Party's account
in a bank to be designated by such Party in writing.

5.6 Reports. All amounts payable under this Agreement shall be
accompanied by a report listing the gross selling price of each Collaboration
Product sold during such period on a product-by-product and country-by-country
basis, and the calculation of Net Revenue based on such sales, including all
other information necessary to determine the appropriate amount of such royalty
payments, and any additional information or reports required under the
Agreement.

5.7 Records and Audit. For a period of three (3) years after the royalty
period to which the records relate, each Party shall keep complete and accurate
records pertaining to the sale or other disposition of the Collaboration
Products commercialized by it, in sufficient detail to permit the other Party to
confirm the accuracy of all payments due hereunder. A Party entitled to
payments hereunder shall have the right to cause an independent, certified
public accountant reasonably acceptable to the other Party (and who has executed
a confidentiality agreement with the Party to be audited) to audit such records
to confirm the Net Revenue and royalty payments; provided, however, that such
auditor shall not disclose the audited Party's confidential information to the
other Party, except to the extent such disclosure is necessary to verify the
amount of royalties and other payments due under this Agreement. In no event
may such accountant disclose the names of specific customers, price lists, or
the prices charged to specific customers. A copy of any report provided by such
accountant shall be provided to the audited Party at the time that it is
provided to the auditing Party. Such audits may be exercised once a year,
within three (3) years after the royalty period to which such records relate,
upon a mutually acceptable date(s) and upon not less than thirty (30) days
advance notice, and shall be conducted during normal business hours. Any
amounts shown to be owing by such audits shall be paid immediately with interest
in the amount of one percent (1%) per month (or the maximum amount permitted by
law, if less) from the date first owed until paid. The auditing Party shall
bear the full cost of such audit unless such audit discloses that royalties
actually paid by the audited Party are more than five percent (5%) less from the
amount of royalties and/or other payments actually owed. In such case, the
audited Party shall bear the full cost of such audit. The terms of this Section
5.7 shall survive any termination or expiration of this Agreement for a period
of two (2) years.

5.8 Withholding of Taxes. All turnover, income and other taxes levied on
account of the royalties and other payments accruing or made to a Party under
this Agreement shall be paid by such Party. If provision is made in law or
regulation for withholding of taxes of any type, levies or other charges with
respect to any royalty or other amounts payable under this Agreement by a Party
to the other Party, then such paying Party shall be entitled to deduct such tax,
levy or charge from the royalty or other payment to be made by such Party and
pay such tax, levy or charge to the proper taxing authority. A receipt of
payment of the tax, levy or charge secured shall be promptly delivered to the
other Party, together with copies of all pertinent communications from or with
such governmental authorities with respect thereto. Such paying Party agrees to
cooperate with the other Party in any effort in claiming any exemption from such
deductions or withholdings under any double taxation or similar agreement or
treaty from time to time in force and in minimizing the amount required to be so
withheld or deducted, such cooperation to consist of providing receipts of
payment of such withheld tax or other documents reasonably available to the
paying Party.

(b) was generally available to the public or otherwise part of the
public domain at the time of its disclosure to the receiving Party;

(c) became generally available to the public or otherwise part of
the public domain after its disclosure and other than through any act or
omission of the receiving Party in breach of this Agreement; or

(d) was disclosed to the receiving Party, other than under an
obligation of confidentiality, by a Third Party who had no obligation to the
disclosing Party not to disclose such information to others.

6.3 Authorized Disclosure. Each Party may disclose the other's
Confidential Information to the extent such disclosure is reasonably necessary
in filing or prosecuting patent applications, prosecuting or defending
litigation, complying with applicable governmental regulations or conducting
preclinical or clinical trials, provided that if a Party is required by law or
regulation to make any such disclosure of the other Party's Confidential
Information it will except where impracticable for necessary disclosures, for
example in the event of medical emergency, give reasonable advance notice to the
other Party of such disclosure requirement and, except to the extent
inappropriate in the case of patent applications, will use its best efforts to

Dendreon's suggestions, regarding the prosecution of such Patents. Upon Kirin's
reasonable request and at its sole expense, Dendreon will make Reasonable
Efforts to assist Kirin in the filing of any Collaboration Patent. As soon as
practical subsequent to filing, Kirin will provide Dendreon with an English
language translation of any filing. In addition, Kirin will copy Dendreon with
any official action and Kirin submissions in such Patents, including an English
translation summary thereof. If Kirin fails to file, prosecute, issue or
maintain a particular Collaboration Patent in the Dendreon Territory within
sixty (60) days of receipt of a request from Dendreon that Kirin take such
action, Dendreon shall have the right to file, prosecute, issue or maintain such
Collaboration Patent in the Dendreon Territory.

a Party having the right to enforce a Collaboration Patent pursuant to this
Section 7.3 fails to bring an action or proceeding against a suspected infringer
within a period of ninety (90) days after having knowledge of such infringement
in the Field, the other Party shall have the right to bring and control an
action against such infringer by counsel of its own choice. If one Party brings
any such action or proceeding, the other Party agrees to be joined as a Party
plaintiff if necessary to prosecute the action and to give the first Party
reasonable assistance and authority to file and prosecute the suit. The Party
controlling a suit hereunder shall, at the other Party's expense, retain any and
all recovery from such suit. The Party controlling a suit hereunder shall not
settle or consent to an adverse judgment in any such action which would have a
material adverse effect on the rights or interests of the other Party without
the prior express written consent of the other Party.

7.4 Third Party Patent Rights. Except as otherwise provided in this
Agreement or the Commercialization Agreement, neither Party makes any warranty
with respect to the validity, perfection or dominance of any Collaboration
Patent or other proprietary right or with respect to the absence of rights of
Third Parties which may be infringed by the manufacture or sale of any
Collaboration Product.

7.5 Third Party Claims in the Kirin Territory. If a Third Party asserts

any Collaboration Product in the Kirin Territory, Kirin will be solely
responsible for defending against any such assertions at its cost and expense.
Each Party will give prompt written notice to the other of any such

claim. Dendreon will assist in the defense of any such claim as reasonably
requested by Kirin, at Kirin's expense, and may retain separate counsel at its
own expense. Prior to settling any such claim, Kirin shall consider in good
faith any rights and interests of Dendreon that may be adversely affected by
such settlement and shall use good faith efforts to minimize such affect.

be solely responsible for defending against any such assertions at its cost and
expense. Each Party will give prompt written notice to the other of any such
claim. Kirin will assist in the defense of any such claim as reasonably
requested by Dendreon, at Dendreon's expense, and may retain separate counsel at
its own expense. Prior to settling any such claim, Dendreon shall consider in
good faith any rights and interests of Kirin that may be adversely affected by
such settlement and shall use good faith efforts to minimize such affect.

7.7 Third Party Royalties. In the event that a Party is required to
obtain a license under a Third Party patent that covers or claims the
manufacture, use or sale of a Collaboration Product in order to practice a
Collaboration Patent to sell such Collaboration Product as permitted in this
Agreement, then provided that such Party shall disclose the relevant portions of
such license under such Third Party patent to the other Party in English and, if
any, the extent of any alleged infringement, such Party shall be entitled to
deduct [ * ] of any royalties owing to such Third Party based on the sale of
such Collaboration Products under such license from amounts owing to the other
Party, subject to a maximum royalty reduction of [ * ] of the amounts that
otherwise would be owed by such Party under this Agreement.
