	 	 8.2.3.
	  Maintenance Payments. In order to maintain the license rights granted by Collaborator to Amgen pursuant to
Sections 3.3 (Licensed Collaborator Patents) and 3.4 (Licensed Collaborator Know-How), Amgen shall be required to make maintenance fee payments as set forth in the table below. Should Amgen fail to make any such payment when due, Collaborator shall
have the right to terminate the licenses granted to Amgen pursuant to such Sections 3.3 (Licensed Collaborator Patents) and 3.4 (Licensed Collaborator Know-How) by thirty (30) days written notice to Amgen, as Collaborator’s sole and
exclusive remedy with respect to such failure to pay. Such termination shall be automatically effective as of the thirty-first (31st) day following
Amgen’s receipt of such notice unless Amgen has cured by making the required payment within such thirty (30) day period, in which case such termination notice shall be of no force or effect. As of the effective date of termination of
Amgen’s licenses pursuant to such Sections 3.3 (Licensed Collaborator Patents) and 3.4 (Licensed Collaborator Know-How), Amgen’s payment obligations pursuant to this Section 8.2 (License Payments by Amgen) shall terminate.

Collaborator’s grants of license to Amgen pursuant to Sections 3.3 (Licensed Collaborator Patents) and 3.4 (Licensed Collaborator Know-How), which licenses are perpetual and irrevocable (except as set forth in Section 8.2.3 (Maintenance
Payments)) and which survive any termination of this Agreement. The payment obligations of this Section 8.2 (Amgen Payments) shall therefore likewise survive any such termination or expiration of this Agreement (without prejudice to
Collaborator’s termination rights pursuant to Section 8.2.3 (Maintenance Payments); and without prejudice to the last sentence of Section 8.2.3 (Maintenance Payments)).

	8.3.	Royalty Payments. 

  

	 	8.3.1.	 Collaborator Payments to Amgen. Collaborator shall pay Amgen the following royalty amounts with respect to annual Collaborator Net Sales during the Term:


  

				
	 Annual Net Sales Amount
	  	Royalty
Percentage	 
	 That portion of aggregate annual Collaborator Net Sales (across all indications) less than $[*]
	  	[	*]%
	 That portion of aggregate annual Collaborator Net Sales (across all indications) equal to or in excess of $[*]
	  	[	*]%

  

	 	 8.3.2.
	  Calculation of Royalty Tiers. A fiscal year beginning on April 1st and ending on March 31st shall be used for the purposes of calculating annual
Collaborator Net Sales in the determination of royalty amounts payable pursuant to Section 8.3.1 (Collaborator Payments to Amgen). 


  

	 	8.3.3.	 Amgen Payments to Collaborator. Amgen shall pay Collaborator [*]% of Amgen Net Sales during the Term as royalty amounts. 

  

	 	8.3.4.	 No Royalty on Amgen Sales Outside Territory. For the avoidance of doubt, no royalty and, except as expressly provided in Section 8.2.2 (Milestone Payments), no
other payments shall be owed by Amgen to Collaborator with respect to development, receipt of any Regulatory Approval, or sales of Dmab by or on the account of Amgen, its Affiliates or licensees outside the Territory for any indication.


  

	8.4.	Appropriate Measure of Value. Each of the Parties acknowledges that the value provided by the other hereunder is comprised of many related items, including
intellectual property of various types, access to development and commercial expertise, clinical data and other financial and non-financial consideration and that the royalties set forth in Section 8.3 (Royalty Payments) are intended to capture
such value as an aggregate. Therefore the increase, decrease or lapse of any particular items or rights shall not affect the amount of such royalty, and the Parties agree that both the amount and duration of the royalties set forth in this Section
are reasonable. 

  

	8.5.	Calculation of Net Sales. In calculating Net Sales: 

  

	 	8.5.1.	 Free Products. Any disposal of Dmab at no charge for, or use of Dmab without charge in, clinical or preclinical trials, given as free samples, or distributed at no
charge to patients unable to purchase the same shall not be included in Net Sales. 

  

	 	8.5.2.	  Bundled Products. Where Dmab is sold in a Bundle, then for the purposes of calculating the Net Sales under this Agreement, such Dmab shall be deemed to
be sold for an amount equal to (X÷Y) × Z, where: X is the average sales price during the applicable reporting period generally achieved for Dmab in the Territory; Y is the sum of the average sales price during the applicable reporting
period generally achieved in the Territory, when sold alone, by each pharmaceutical product included in the Bundle; and Z equals the price at which the Bundle was actually sold. In the event that Dmab or one or more of the 



  

 Page 34 of 65 









	 	 
other pharmaceutical products in the Bundle are not sold separately, the Parties shall confer in good faith to determine an equitable fair market price to
apply to such bundled Dmab. 


  

	8.6.	Reports. Beginning with the Calendar Quarter after the First Commercial Sale of Dmab in the Territory and thereafter for each Calendar Quarter in which royalties are payable
until the expiration of the Payor Party’s obligation to pay royalties hereunder, royalty payments and reports of the sale of Dmab for each Calendar Quarter will be calculated and delivered by the Payor Party to the Payee Party under this
Agreement within forty-five (45) days of the end of each such Calendar Quarter. In addition, such reports for the first Calendar Quarter of each Calendar Year shall be delivered by the Payor Party to the Payee Party within five
(5) business days of the end of such Calendar Quarter using the best estimate of the Payor Party, with a final report (and the accompanying royalty payments) sent no later than forty-five (45) days of the end of such Calendar Quarter. Each
payment of royalties will be accompanied by a report of Net Sales of Dmab stating: (a) Net Sales of Dmab by or on behalf of the Payor Party during the applicable Calendar Quarter (detailed with gross invoiced amounts, deductions and Net Sales);
and (b) a calculation of the royalty payment due from the Payor Party hereunder for such Calendar Quarter. Any reports which contain currency conversions shall provide the details and background information used to calculate such conversions.


  

	8.7.	No Wrongful Reductions. The Payor Party shall not attempt to reduce compensation rightly due to the Payee Party hereunder by shifting compensation otherwise payable to the
Payor Party from a Third Party with respect to Dmab to another product or service for which no royalties are payable by it hereunder. 

  

	8.8.	Development Cost Sharing. In addition to the other payments referenced herein, Collaborator shall pay to Amgen a share of Amgen Development Costs including those for the
third Calendar Quarter of 2007 and thereafter: 

  

	 	8.8.1.	 Amounts. Collaborator’s share of Amgen Development Costs shall be as set forth in the below table, subject in each case to the maximum amounts described in
Section 8.8.2 (Maximum Payments): 

  

				
	 Calendar Year
	  	Collaborator Share	 
	 2007-2009
	  	[	*]%
	 2010 and thereafter
	  	[	*]%

  

	 	8.8.2.	  Maximum Payments. Notwithstanding the foregoing, Collaborator’s payment obligations pursuant to this Section 8.8 (Development Cost Sharing)
shall be subject to a maximum payment as set forth below for each Calendar Year (each, an “Annual Maximum”). In addition, total, aggregate amounts payable by Collaborator pursuant to this Section 8.8 (Development Cost Sharing)
shall not exceed $[*] (the “Aggregate Maximum”). In the event the amount otherwise payable in a Calendar Quarter (“Q1; Q2; Q3 or Q4”, as appropriate) would exceed: [*] (the “Quarterly
Maximum”) then Collaborator shall pay only such Quarterly Maximum. Since there will be only two quarterly payments by Collaborator in 2007 (due to the Effective Date of this Agreement occurring 



  

 Page 35 of 65 









	 	 
during Q3 of 2007), the Quarterly Maximum for Q3 of 2007 shall be [*] of the Annual Maximum for 2007, and the Quarterly Maximum for Q4 of 2007 shall be the
Annual Maximum for 2007 less the amount paid by Collaborator pursuant to this section for Q3 of 2007. No [*] the Annual Maximum for a particular Calendar Year nor [*] the Quarterly Maximum for a particular Calendar Quarter shall [*]. No amounts in
excess of the Aggregate Maximum shall be payable by Collaborator pursuant to this Section 8.8 (Development Cost Sharing).

	 	8.8.3.	 Reports. Within thirty (30) days of the end of each Calendar Quarter, Amgen shall provide Collaborator with a report specifying in reasonable detail the Amgen
Development Costs incurred or paid by Amgen in such Calendar Quarter, as well as any other costs for which Amgen is entitled reimbursement hereunder (such as those incurred pursuant to Section 4.18 (Transition in Oncology Development)). In
addition, for the first Calendar Quarter of each Calendar Year Amgen shall provide Collaborator a non-binding estimate of Collaborator’s share of Amgen Development Costs, as well as any other costs for which Amgen is entitled reimbursement
hereunder (such as those incurred pursuant to Section 4.18 (Transition in Oncology Development)) for such Calendar Quarter within five (5) business days of the end of such Calendar Quarter. Amgen Development Costs may be attributed by
Amgen to either the Calendar Quarter in which they are paid or incurred, but no amount shall be attributed to more than one Calendar Quarter. 

  

	 	8.8.4.	 Payments. Collaborator shall pay Amgen its share of Amgen Development Costs in accordance with Section 8.10 (Payment Method) within thirty (30) days of
receiving Amgen’s report pursuant to Section 8.8.3 (Reports). For the avoidance of doubt, except as expressly set forth in Section 15.3.3 (Development Cost Share), Collaborator’s payment obligation with respect to Amgen
Development Costs shall remain in effect until the Aggregate Maximum has been paid in full. 

  

	 	8.8.5.	 Example. The Development Costs Example Schedule sets forth an example of the calculation of Collaborator’s share of Amgen Development Costs.


  

	8.9.	No Other Compensation. Other than as explicitly set forth (and as applicable) in this Agreement, neither Party shall be obligated to pay any additional fees, milestone
payments, royalties or other payments of any kind to the other under this Agreement. 

  

	8.10.	 Payment Method. All payments made hereunder between the Parties shall be made in U.S. Dollars except as set forth in Section 8.13 (Blocked Currency).
The Payor Party shall pay all sums due hereunder by check, wire transfer, or electronic funds transfer 



  

 Page 36 of 65 









	 	 
(EFT) in immediately available funds. Each Party will promptly notify the other Party of the appropriate account information to facilitate any such payments.
Regardless of the amounts of any royalties or other payments due under this Agreement or any other agreement between the Parties or their Affiliates, all amounts payable under this Agreement shall be paid in full (subject to Section 8.15
(Withholding) and Section 8.16 (VAT)). 


  

	8.11.	Change in Accounting Periods. From time to time, either Party may change its company-wide (or Territory-wide) accounting and financial reporting practices from Calendar
Quarters and Calendar Years to fiscal quarters and fiscal years or vice versa. If a Party notifies the other of a change in its accounting and financial reporting practices from Calendar Quarters and Calendar Years to fiscal quarters and fiscal
years or vice versa, then thereafter, beginning with the period specified in the notice, the payment, reporting and other obligations of such Party hereunder related to Calendar Quarters and Calendar Years shall be deemed satisfied by compliance
therewith in accordance with the new reporting periods (fiscal reporting periods or calendar reporting periods, as the case may be) instead of the previously utilized reporting periods. The Parties shall cooperate in good faith to minimize any
disruption caused by any such change. Notwithstanding the foregoing, any change in Collaborator’s accounting periods shall not affect the timing or amount of Collaborator’s payment obligations pursuant to Section 8.8 (Development Cost
Sharing). 

  

	8.12.	Audits. The Payor Party shall keep complete and accurate records pertaining to the development and sale of Dmab in the Territory in sufficient detail to permit the Payee
Party to confirm the accuracy of all payments due hereunder, and such records shall be open (in such form as may be available or reasonably requested by a certified public accountant in accordance with this Section 8.12 (Audits)) to inspection
for [*] following the end of the period to which they pertain. The Payee Party shall have the right, at its own expense, to have an independent, certified public accountant, selected by such Payee Party review the records of the Payor Party upon
reasonable notice (which shall be no less than thirty (30) days prior written notice) and during regular business hours. Upon request, the accountant shall execute a confidentiality agreement reasonably required by the Payor Party. The report
of such accountant shall be made available to both Parties simultaneously, promptly upon its completion. The Payee Party’s audit rights with respect to any Calendar Year shall expire [*] after the end of such year and the books and records for
any particular Calendar Year shall only be subject to one (1) audit. Should the inspection lead to the discovery of a discrepancy to the Payee Party’s detriment, then the Payor Party shall pay to the Payee Party the amount of the
discrepancy plus interest accrued at the Contract Interest Rate, compounded daily from the day the relevant payment(s) were due. Should the inspection lead to the discovery of a discrepancy to the Payor Party’s detriment, then the Payee Party
shall pay to the Payor Party the amount of the discrepancy without interest. The Payee Party shall pay the full cost of the inspection unless the discrepancy is to the Payee Party’s detriment and is greater than [*] percent ([*]%) of the amount
actually paid for the audited period, in which case the Payor Party shall pay the cost of such inspection. 

  

	8.13.	 Blocked Currency. If at any time legal restrictions in the Territory prevent the prompt remittance of any payments with respect to sales therein, the Payor
Party shall have the 



  

 Page 37 of 65 









	 	 
right and option to make such payments by depositing the amount thereof in local currency to the Payee Party’s account in a bank or depository in the
Territory. 


  

	8.14.	Taxes. All Taxes levied on account of a payment made by a Payor Party to a Payee Party pursuant to this Agreement will be the responsibility of and paid by the Payee Party or
shall be subject to the withholding and remittance provisions of Section 8.15 (Withholding). 

  

	8.15.	Withholding. In the event that Laws require a Payor Party to withhold Taxes with respect to any payment to be made by such Party to the Payee Party pursuant to this
Agreement, the Payor Party will withhold such Taxes from the amount due and furnish the Payee Party with proof of payment of such Taxes. The Payor Party will provide reasonable assistance to the Payee Party in its efforts to claim an exemption of
Taxes, obtain a refund of Taxes withheld, or obtain a credit with respect to such Taxes paid. In order for the Payee Party to secure an exemption from, or a reduction in, any withholding of Taxes, the Payee Party shall provide to the Payor Party
such forms as reasonably required for each type of payment to be made pursuant to the Agreement for which an exemption from, or a reduction in, any withholding of Taxes is claimed. Each Party shall provide the other any cooperation reasonably
requested to minimize any withholding obligation (e.g., by providing the necessary tax forms upon request). 

  

	8.16.	VAT. All payments due a Payee Party from a Payor Party pursuant to this Agreement shall be paid exclusive of any VAT (which, if applicable, shall be payable by the Payor
Party upon receipt of a valid VAT invoice). 

  

	8.17.	Late Payment. Any payments or portions thereof due hereunder which are not paid when due shall bear interest at the Contract Interest Rate, compounded daily, calculated on
the number of days such payment is delinquent. This Section 8.17 (Late Payment) shall in no way limit any other remedies available to either Party. 

  

	8.18.	Third Party Royalties. Except as expressly set forth in Sections 8.15 (Withholding) and 8.16 (VAT), neither Party shall have the right to make any deduction from amounts
otherwise payable pursuant to this Agreement on account of any royalty or other amount payable to any Third Party. 

  

	9.	SETTLEMENT OF PATENT DISPUTES 

  

	9.1.	 Settlement. The Parties hereby intend that this Agreement fully and finally dispose, compromise and settle any and all patent disputes between Collaborator
and its Affiliates, and its and their successors and assigns, and Amgen and its Affiliates, and its and their successors and assigns, with respect to the Settled Patents. [*] In consideration of this settlement, the Parties hereby agree as follows:
Collaborator covenants that neither it, its Affiliates nor sublicensees, nor its or their successors or assigns will [*] the Territory. Collaborator, for itself, its Affiliates and each of its and their successors and assigns, hereby [*] the
Territory. Amgen covenants that neither it, its Affiliates nor sublicensees, nor any of its or their successors or assigns will initiate or file, or request, assist or cause any Third Party to [*] the Territory. Amgen, for itself, its Affiliates and
each of its and their successors and assigns, hereby [*] the Territory. The foregoing [*] in this Section 9.1 (Settlement) are subject to the Parties’ respective rights to control preparation, filing (including filing for correction of
claims or specifications), 



  

 Page 38 of 65 









	 	 
prosecution, maintenance, defense (including responses to patent office communications, office actions, oppositions, interferences and challenges) and
enforcement of the Settled Patents as specified in Article 10 (Intellectual Property) (following expiration or termination of this Agreement, as may be modified by the provisions of Article 15 (Term and Termination)), and the exercise of a
Party’s rights in accordance with Article 10 (Intellectual Property) (as may be so modified following expiration or termination of this Agreement) shall not be deemed a breach of the [*] under this Section 9.1 (Settlement).



  

	10.	INTELLECTUAL PROPERTY 

  

	10.1.	Ownership. Except to the extent expressly specified to the contrary in this Agreement: (i) each Party shall retain and own all right, title, and interest in and to all
patent rights, trade secrets, proprietary rights and other intellectual property rights conceived or created solely by such Party; (ii) the Parties shall jointly own all right, title, and interest in and to all patent rights, trade secrets,
proprietary rights and other intellectual property rights conceived or created jointly by the Parties and, subject to the provisions of this Agreement (including those licenses granted pursuant to Article 3 (Grant of License)), neither Party shall
have any duty to account or obtain the consent of the other Party (such consent deemed given hereunder) in order to exploit or license such intellectual property rights; and (iii) inventorship and authorship of any invention or work of
authorship conceived or created by either Party, or jointly by the Parties, shall follow the rules of the U.S. Patent and Trademark Office and the Laws of the United States (without reference to any conflict of law principles).


  

	10.2.	Transition and Cooperation. 

  

	 	10.2.1.	 Transition. [*] The Parties shall cooperate to promptly transition such documents, filings and other information, execute all agreements, certificates, instruments and
documents, and take such other actions, in each case as necessary or reasonably requested by the other Party to effectuate such transition of control consistent with this Article 10 (Intellectual Property). 

  

	 	10.2.2.	 Cooperation. Each Party shall provide the Party in control [*] and the controlling Party shall reimburse the assisting Party’s reasonable, documented out-of-pocket
expenses incurred in connection therewith. Without limiting the foregoing, if reasonably necessary for standing or to satisfy other requirements to file, pursue or maintain an action in accordance with this Article 10 (Intellectual Property), a
non-controlling Party will join such action at the controlling Party’s request, and the controlling Party shall reimburse the non-controlling Party’s reasonable, documented out-of-pocket expenses incurred in connection therewith. Each
Party shall, upon the request of the other Party, execute all agreements, certificates, instruments and documents necessary to enable the requesting Party to evidence, register, protect or perfect its rights hereunder, including short-form licenses
and other documents necessary to register its licenses with the United States Patent and Trademark Office, and corresponding offices in other countries.

	10.3.	 Prosecution and Maintenance. 

  

	 	10.3.1.	In Territory. 

  

	 	10.3.1.1.	 Collaborator [*] Prosecution. Collaborator shall control, itself or through outside counsel reasonably acceptable to the Parties and directed by Collaborator,
the preparation, filing (including filing for correction of claims or specifications), prosecution, maintenance and defense (including responses to patent office communications, any office actions, oppositions, interferences and challenges (whether
before a patent authority or judicial body) related thereto) in the Territory [*] at Collaborator’s expense, as well as preparation and filing for any patent term extensions or similar protections therefor.[*] 

  

	 	10.3.1.2.	 Amgen [*] Prosecution. [*] Amgen may, upon written notice to Collaborator and at Amgen’s sole cost, control the preparation, filing (including filing for
correction of claims or specifications), prosecution, maintenance and defense (including responses to patent office communications, any office actions, oppositions, interferences and challenges related thereto) of such item within the Territory
Patents and Trademarks thereafter in accordance with this Section 10.3.1.2 (Amgen [*] Prosecution) (any item so assumed, an “Amgen Assumed Item”). Amgen shall control, itself or through outside counsel reasonably acceptable to
the Parties and directed by Amgen, the preparation, filing (including filing for correction of claims or specifications), prosecution, maintenance and defense (including responses to patent office communications, any office actions, oppositions,
interferences and challenges related thereto) of Amgen Assumed Items in the Territory, at Amgen’s expense, as well as preparation and filing for any patent term extensions or similar protections therefor.[*]. 

  

	 	10.3.2.	 Outside Territory. Amgen shall control and be solely responsible for the preparation, filing (including filing for correction of claims or specifications),
prosecution, maintenance, defense (including responses to patent office communications, any office actions, oppositions, interferences and challenges (whether before a patent authority or judicial body) related thereto) and all other actions with
respect to its patent rights, trademark rights and other intellectual property outside the Territory, at its sole cost and expense. Amgen shall control and be solely responsible for the preparation, filing (including filing for correction of claims
or specifications), prosecution, maintenance, defense (including responses to patent office communications, any office actions, oppositions, interferences and challenges (whether before a patent authority or judicial body) related thereto) and all
other actions with respect to [*]. 

  

	10.4.	  Defense and Settlement of Third Party Claims. If a Third Party asserts that a patent right or other right owned by it is infringed by the manufacture,
use, sale or importation [*] by a Party (the “Defending Party”), the Defending Party shall have the sole right to defend against any such assertions at its sole cost. If such Third Party asserts that a patent right or other right
owned by it is infringed by the manufacture, use, sale or 



  

 Page 40 of 65 









	 	 
importation [*] by both of the Parties, then the Parties shall meet and confer, and both Parties shall have the sole right to defend against any such
assertions with respect to its activities at their respective sole cost. The other Party shall assist the Defending Party and cooperate in any such litigation at the Defending Party’s request, and the Defending Party shall reimburse such other
Party any reasonable, documented, out-of-pocket costs incurred in connection therewith. Subject to such control, the other Party may join any defense and settlement pursuant to this Section 10.4 (Defense and Settlement of Third Party Claims),
with its own counsel at its sole cost. Regardless of which Party is the Defending Party (or if both Parties are a Defending Party), the Defending Party shall seek and reasonably consider the other Party’s comments before determining the
strategy for such matter. Without limiting the foregoing, the Defending Party shall keep the other Party advised of all material communications, actual and prospective filings or submissions regarding such action, and shall provide the other Party
copies of and an opportunity to review and comment on any such communications, filings and submissions. [*] The Defending Party shall not settle or consent to the entry of any judgment in any enforcement action hereunder without the other
Party’s prior written consent, not to be unreasonably withheld or delayed. Each Party shall keep the other reasonably informed of all claims and actions governed by this Section 10.4 (Defense and Settlement of Third Party Claims).



  

	10.5.	Enforcement. 

  

	 	10.5.1.	 In Territory. Each Party shall promptly notify the other Party in writing if it reasonably believes that any [*] are infringed or misappropriated by a Third Party in
the Territory. 

  

	 	10.5.1.1.	 Collaborator [*] Enforcement. [*] 

  

	 	10.5.1.2.	 Amgen [*] Enforcement. [*] 

  

	 	10.5.2.	 Outside Territory. [*] 

  

	10.6.	Allocation of Recoveries. All Recoveries shall first be applied to reimbursement of the unreimbursed legal fees and expenses reasonably incurred by the Parties in the action
from which such Recovery was received on a pro rata basis. Any Recoveries that are left over after such reimbursement shall be allocated between the Parties [*] percent ([*]%) to Collaborator and [*] percent ([*]%) to Amgen. Amgen shall have the
sole right to retain any and all recoveries with respect to the enforcement of any Amgen intellectual property or proprietary right, Licensed Collaborator Patents, Licensed Collaborator Know-How or Joint Patents outside the Territory. After any
termination or expiration of this Agreement, Amgen shall have the right to retain one hundred percent (100%) of any Recoveries left over after reimbursement of costs. 

  

	10.7.	 Patent Term Extensions. Each Party shall provide reasonable assistance to the other Party (Amgen to Collaborator with respect to Licensed Amgen Patents and
Collaborator to Amgen with respect to Licensed Collaborator Patents) in connection with obtaining SPCs to Licensed Amgen Patents and Licensed Collaborator Patents consistent with the rights of the other Party to control such matters as specified in
Section 10.3 (Prosecution and Maintenance). To the extent reasonably and legally required in order to obtain any such SPC in a particular country, each Party shall make available to the 



  

 Page 41 of 65 









	 	 
other a copy of the necessary documentation to enable such other Party to use the same for the purpose of obtaining the SPC in such country.



  

	10.8.	Employee Agreements. Prior to beginning work relating to any aspect of the subject matter of this Agreement and/or being given access to Licensed Amgen Know-How or Licensed
Collaborator Know-How or Confidential Information of the other Party, each employee, consultant or agent of Collaborator or Amgen, respectively, shall have signed or shall be bound to a non-disclosure and invention assignment agreement pursuant to
which each such person shall agree to comply with all of the obligations of Collaborator or Amgen, as appropriate, substantially including: (i) promptly reporting any Information, as appropriate; (ii) assigning to Collaborator or
Amgen, as appropriate, all of his or her right, title and interest in and to any such Information; (iii) cooperating in the preparation, filing, prosecution, maintenance, enforcement and defense of any intellectual property rights;
(iv) performing all acts and signing, executing, acknowledging and delivering any and all papers, documents and instruments required for effecting the obligations and purposes of this Agreement; and (v) abiding by the obligations of
confidentiality and non-use set forth in this Agreement. It is understood and agreed that any such non-disclosure and invention assignment agreement need not be specific to this Agreement, and that the operation of a collective employment policy
sufficient to achieve the intent of the foregoing shall be sufficient to satisfy such obligation. Each Party shall be responsible for any compensation and any other payments due to its own inventors of any patent right. 

  

	10.9.	Patent Marking. Dmab marketed and sold by Collaborator hereunder shall be marked with appropriate patent numbers or indicia of Licensed Amgen Patents, to the extent permitted
by Law in the Territory. Dmab marketed and sold by Amgen hereunder in the Territory shall be marked with appropriate patent numbers or indicia of Licensed Collaborator Patents, to the extent permitted by Law in the Territory.


  

	11.	CONFIDENTIALITY AND PUBLICATIONS 

  

	11.1.	Confidentiality; Exceptions. Except to the extent expressly authorized by this Agreement or otherwise agreed in writing, the Parties agree that, during the Term and for [*]
([*]) years thereafter, the receiving Party shall keep confidential and shall not publish or otherwise disclose or use for any purpose other than as provided for in this Agreement any confidential and proprietary information and materials furnished
to it by the other Party pursuant to this Agreement (collectively, “Confidential Information”). Collaborator shall have no right to and shall not utilize any Confidential Information of Amgen for activities outside the Territory
(including, with respect to the research, development or commercialization of any Competing Product outside the Territory). For clarity, Confidential Information of a Party shall include, without limitation, all information and materials disclosed
by such Party or its designee that (i) is marked as “Confidential,” “Proprietary” or with similar designation at the time of disclosure or (ii) by its nature can reasonably be expected to be considered Confidential
Information by the recipient. Information disclosed orally shall not be required to be identified as such to be considered Confidential Information. Notwithstanding the foregoing, Confidential Information shall not include any information to the
extent that it can be established by written documentation by the receiving Party that such information: 

  

	 	11.1.1.	was already known to the receiving Party, other than under an obligation of confidentiality (except to the extent such obligation has expired or an exception is applicable under the
relevant agreement pursuant to which such obligation was established), at the time of disclosure; 

  

 Page 42 of 65 









	 	11.1.2.	 was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party; 

  

	 	11.1.3.	 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; 

  

	 	11.1.4.	 was independently developed by the receiving Party as demonstrated by documented evidence prepared contemporaneously with such independent development; or


  

	 	11.1.5.	 was disclosed to the receiving Party, other than under an obligation of confidentiality (except to the extent such obligation has expired or an exception is applicable under
the relevant agreement pursuant to which such obligation was established), by a Third Party who had no obligation to the disclosing Party not to disclose such information to others. 

  

	11.2.	Authorized Disclosure. Except as expressly provided otherwise in this Agreement, each Party may use and disclose Confidential Information of the other Party solely as
follows: (i) under appropriate confidentiality provisions substantially equivalent to those in this Agreement: (a) in connection with the performance of its obligations or as reasonably necessary or useful in the exercise of its
rights under this Agreement, including the right to grant licenses or sublicenses as permitted hereunder, and (b) to the extent such disclosure is reasonably necessary or useful in conducting development under this Agreement; (ii) to the

	14.	INDEMNIFICATION 

  

	14.1.	 Indemnity. Subject to the remainder of this Article 14 (Indemnification), Collaborator shall defend, indemnify, and hold harmless Amgen, its Affiliates, and
their respective directors, officers, employees and agents (collectively, “Amgen Indemnitees”), at Collaborator’s cost and expense, from and against any and all liabilities, losses, costs, damages, fees or expenses (including
reasonable legal expenses and attorneys’ fees incurred by any Amgen Indemnitees until such time as Collaborator has acknowledged and assumed its indemnification obligation hereunder with respect to a claim) paid to a Third Party (collectively,
“Losses”) arising out of any claim, action, lawsuit, or other proceeding (collectively, “Claims”) brought against any Amgen Indemnitee by a Third Party to the extent such Losses result from (i) the negligence
or willful misconduct of Collaborator, or its Affiliates or agents, (ii) a breach by Collaborator of this Agreement, (iii) a violation of Law by Collaborator, or its Affiliates or agents, or (iv) Collaborator’s, its

 Page 47 of 65

(y) a violation of Law by Amgen, or its Affiliates or agents, or (z) Amgen’s, its Affiliate’s or its licensee’s (other than Collaborator, its Affiliates or its licensees) development or commercialization of Dmab, but

	14.2.	 Claim for Indemnification. Whenever any Claim or Loss shall arise for which a Collaborator Indemnitee or an Amgen Indemnitee (the “Indemnified Party”)
may seek indemnification under this Article 14 (Indemnification), the Indemnified Party shall promptly notify the other Party (the “Indemnifying Party”) of the Claim or Loss and, when known, the facts constituting the basis for the
Claim; provided, however, that the failure by an Indemnified Party to give such notice or to otherwise meet its obligations under this Section 14.2 (Claim for Indemnification) shall not relieve the Indemnifying Party of its indemnification
obligation under this Agreement except and only to the extent that the Indemnifying Party is actually prejudiced as a result of such failure. The Indemnifying Party shall have exclusive control of the defense and settlement of all Claims for which
it is responsible for indemnification and shall promptly assume defense thereof at its own expense. The Indemnified Party shall not settle or compromise any Claim by a Third Party for which it is entitled to indemnification without the prior written
consent of the Indemnifying Party, unless the Indemnifying Party is in breach of its obligation to defend hereunder. In no event shall the Indemnifying Party settle any Claim without the prior written consent of the other Party if such settlement
does not include a complete release from liability on such Claim or if such settlement would involve undertaking an obligation other than the payment of money, would bind or impair the other Party, or includes any admission of wrongdoing or that any
intellectual property or proprietary right of the other Party is invalid or unenforceable. The Indemnified Party shall reasonably cooperate with the Indemnifying Party at the Indemnifying Party’s expense and shall make available to the
Indemnifying Party reasonably requested information under the control of the Indemnified Party, which information shall be subject to Article 11 (Confidentiality and Publications).

 News Release 
 AMGEN AND DAIICHI SANKYO ANNOUNCE 
 AGREEMENT FOR DENOSUMAB IN JAPAN

 Amgen Grants Daiichi Sankyo Exclusive Rights to Develop and 
 Commercialize Denosumab in Japan 
 FOR IMMEDIATE RELEASE 
 THOUSAND OAKS, Calif. (July 11, 2007) and TOKYO (July 12, 2007) – Amgen (NASDAQ:AMGN) and Daiichi Sankyo Company, Limited (TSE:4568) today announced a collaboration
and license agreement for the development and commercialization of denosumab in Japan. Denosumab is a fully human monoclonal antibody that targets RANK Ligand (an essential mediator of cells that break down bone) and is being investigated for its
potential to treat and prevent a broad range of bone loss conditions including osteoporosis and bone metastases. 
 Under the terms of the agreement, Amgen
has granted Daiichi Sankyo exclusive rights to develop and commercialize denosumab in Japan in post-menopausal osteoporosis and oncology with the potential for additional indications. As part of the agreement, Amgen will receive exclusive worldwide
rights to certain Daiichi Sankyo intellectual property to the extent applicable to denosumab. 









 The financial terms include an upfront payment to Amgen of $20 million. In addition, Daiichi Sankyo will assume all
development costs for denosumab in Japan and will pay approximately $150 million of expected worldwide development costs for denosumab through 2009. In consideration of its intellectual property, Daiichi Sankyo is also eligible to receive milestone
payments dependent on the approval of denosumab in the European Union or Japan, in two indications. In connection with its activities under the collaboration and license agreement, Daiichi Sankyo will pay royalties on annual net sales of denosumab
in Japan in amounts commensurate with a major late stage product for the Japan market. 
 “Daiichi Sankyo is an ideal partner for denosumab,” said
Kevin Sharer, Chairman and CEO of Amgen. “Daiichi Sankyo is uniquely positioned to bring this potential therapy to patients with a wide spectrum of bone-related diseases in Japan.” 
 “Daiichi Sankyo is thrilled to partner with a world leader in biotechnology to gain access to this important antibody product,” said Takashi Shoda, President
and CEO of Daiichi Sankyo. “We believe that denosumab has the potential to be a first-in-class, leading product in Japan for multiple indications within Daiichi Sankyo’s therapeutic areas of focus. Denosumab’s potential applicability
in oncology makes it an important part of the foundation for our growing oncology business.” Daiichi Sankyo has a full range of commercial capabilities, including in the primary care and hospital settings, a track record of successful large,
first-in-class product launches and the financial strength to ensure appropriate investment in the product. 
 About Denosumab 
 Denosumab is a fully human monoclonal antibody that targets RANK Ligand and is being investigated for its potential to prevent and treat a broad range of bone loss
conditions including osteoporosis, bone metastases, treatment-induced bone loss, multiple myeloma and bone erosions in rheumatoid arthritis. Denosumab is the first late-stage investigational therapy that specifically inhibits RANK Ligand, an
essential mediator of the cells that break down bone.

 Forward-Looking Statement: Amgen 
 This news release contains forward-looking statements that involve significant risks and uncertainties, including those discussed below and others that can be found in
our Form 10-K for the year ended Dec. 31, 2006, and in our periodic reports on Form 10-Q and Form 8-K. Amgen is providing this information as of the date of this news release and does not undertake any obligation to update any forward-looking
statements contained in this document as a result of new information, future events or otherwise. 
 No forward-looking statement can be guaranteed and
actual results may differ materially from those we project. The Company’s results may be affected by our ability to successfully market both new and existing products domestically and internationally, clinical and regulatory developments
(domestic or foreign) involving current and future products, sales growth of recently launched products, competition from other products (domestic or foreign), difficulties or delays in manufacturing our products. In addition, sales of our products
are affected by reimbursement policies imposed by third-party payors, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international
trends toward managed care and health care cost containment as well as U.S. legislation affecting pharmaceutical pricing and reimbursement. Government and others’ regulations and reimbursement policies may affect the development, usage and
pricing of our products. Furthermore, our research, testing, pricing, marketing and other operations are subject to extensive regulation by domestic and foreign government regulatory authorities. We or others could identify safety, side effects or
manufacturing problems with our products after they are on the market. Our business may be impacted by government investigations, litigation and products liability claims. Further, while we routinely obtain patents for our products and technology,
the protection offered by our patents and patent applications may be challenged, invalidated or circumvented by our competitors. We depend on third parties for a significant portion of our manufacturing capacity for the supply of certain of our
current and future products and limits on supply may constrain sales of certain of our current products and product candidate development. In addition, we compete with other companies with respect to some of our marketed products as well as for the
discovery and development of new products. Discovery or identification of new product candidates cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate
will be successful and become a commercial product. Further, some raw materials, medical devices and component parts for our products are supplied by sole third-party suppliers.
