Article 3

Scope of Supply Services and Work Orders

     3.1 Scope of Supply Services

Tekmira will provide services for Alnylam in respect of the Manufacture of Product as Bulk Product
or Finished Product, as non-GMP Batches or GMP Batches, and such other services, including without
limitation, project management, Technical Transfer, scale-up and process development, analytical
method development, stability testing, release testing, quality control, quality assurance, Third
Party Management Work, and regulatory support, as may be specified in each Work Order (“Supply
Services”). Subject to the provisions of Article 11, Alnylam agrees to obtain, and Tekmira agrees
to supply, all of Alnylam’s requirements during the Term for Bulk Product and for Finished Product
for non-GMP Batches and other non-clinical studies and for Bulk Product for clinical development,
through the completion of all Phase II Studies of such Product that are initiated prior to the
initiation of the first Phase III Study of such Product, in each case through the provision of the
Supply Services by Tekmira under this Agreement. Alnylam further agrees, in recognition of
Tekmira’s commitments and anticipated scale-up and other efforts hereunder, to pay Tekmira for at
least the Minimum FTE Portion applicable to each Calendar Quarter only during the first three years
of the Term.

     3.2 Contents and Effectiveness of Work Orders

	3.2.1	 	Each request for the Manufacture of a specific Batch will be set forth in a Work Order,
which may also specify Supply Services incidental to or otherwise directly related to the
Manufacture and supply of such Batch.
	 
	3.2.2	 	While a single Work Order may cover the Manufacture of more than one Batch of a particular
Product, no Work Order may cover (i) the Manufacture of Batches of different Products or (ii)
the Manufacture of one or more non-GMP Batches and one or more GMP Batches of the same
Product.
	 
	3.2.3	 	Each request for Supply Services other than the Manufacture of a specific Batch (“Other
Supply Services Work Orders”), such as, for example, scale up and process development
activities, will (except as stated in Section 3.2.1) be set forth in a separate Work Order
that specifically provides for such Supply Services. Either Party may prepare a draft of any
such Other Supply Services Work Order and provide it to the other Party, and, if it does so,
such other Party will accept, reject, or suggest changes to such draft Work Order in writing
within ten (10) Business Days of its receipt of such draft Work Order. No Other Supply
Services Work Order will be effective unless and until it has been agreed to and signed by
authorized representatives of both Parties. Neither Party will be obligated to enter into any
Other Supply Services Work Order, but each Party hereby agrees to be reasonable and to use
good faith in its considerations of draft Other Supply Services Work Orders submitted by the
other Party.

- 10 -

 

	3.2.4	 	Unless otherwise determined in individual situations by the Joint Development and
Manufacturing Committee, Work Orders covering the Manufacture of a non-GMP Batch and related
Supply Services (“non-GMP Batch Work Orders”) will contain or refer to the following elements
as applicable: scope of Supply Services, an estimate of the total Price for all Supply
Services under such Work Order (the “non-GMP Batch Work Order Estimated Price”) (each such
estimate providing details regarding the projected amount of Third Party Management work and
Third Party Costs contained in such estimated Price), Specifications (it being understood that
the Specifications for a non-GMP Batch will be agreed upon by the Joint Development and
Manufacturing Committee using good faith estimates of what is reasonably achievable for such
non-GMP Batch and which Specifications may include “run-and-report” data for which Tekmira
will not be held responsible), date or dates of Alnylam’s delivery of Alnylam Materials and
associated documentation, timeframe for commencement and completion of Supply Services,
deliverables, designation of the additional Applicable Laws and Regulatory Authority(ies) that
will be applicable to the Product to be produced (it being understood that the standard for
Product produced in non-GMP Batches will be based on industry standards and norms agreed to by
the Joint Development and Manufacturing Committee), location of Facilities, reference to
Tekmira Materials and Alnylam Materials, and deviations, if any, from the terms of this
Agreement. Each Party’s representatives on the Joint Development and Manufacturing Committee
shall have the authority to sign, on behalf of their respective Parties, a non-GMP Batch Work
Order, subject to any financial limits to the signing authority of the members of the Joint
Development and Manufacturing Committee based on such Party’s internal controls.
	 
	 	 	In the event the Parties cannot agree upon the content of any non-GMP Batch Work Order or
cannot agree upon a Change Order related to any non-GMP Batch Work Order, then the Joint
Development and Manufacturing Committee shall be authorized to attempt to resolve such
disagreement. If the Joint Development and Manufacturing Committee cannot resolve such
disagreement, the matter shall be resolved in accordance with the provisions of Section
2.6.2.
	 
	3.2.5	 	Work Orders covering the Manufacture of a GMP Batch and related Supply Services (“GMP Batch
Work Orders”) shall contain or refer to the following elements as applicable: scope of Supply
Services, an estimate of the total Price for all Supply Services under such Work Order (the
“GMP Batch Work Order Estimated Price”) (each such estimate providing details regarding the
projected amount of Third Party Management Work and Third Party Costs contained in such
estimated Price), Methods, Specifications, SOPs (and other documentation such as development
or qualification of methods and/or analytics, to the extent designated by the Joint
Development and Manufacturing Committee as relevant), date or dates of Alnylam’s delivery of
Alnylam Materials and its associated documentation, timeframe for commencement and completion
of Supply Services, deliverables, designation of the additional Applicable Laws and Regulatory
Authority(ies) that will be applicable to the Product to be produced, location of Facilities,
reference to Tekmira Materials and Alnylam Materials, and deviations, if any, from the terms
of this Agreement.
	 
	3.2.6	 	With respect to GMP Batch Work Orders, Alnylam will, reasonably and in good faith, prepare a
draft of each such Work Order and provide it to Tekmira for its consideration, and Tekmira
will accept or suggest changes to such draft Work Order in writing within ten (10) Business
Days of Tekmira’s receipt of such draft Work Order. Tekmira shall be reasonable and use good
faith in its considerations of draft GMP Batch Work Orders from Alnylam. No GMP Batch Work
Order will be effective unless and until it has been agreed to and signed by authorized
representatives of both Parties; provided, however, that (i) Tekmira may suggest changes to,
but may not decline to accept, a GMP Batch Work Order to be effected in the

- 11 -

 

	 	 	following two Calendar Quarters for a GMP Batch that was reflected in the most recent GMP
Batch Forecast for such Calendar Quarters and (ii) nothing contained herein shall require
Tekmira to accept any Work Order which contains provisions which are contrary to the
terms of this Agreement. Documents relating to the relevant project, including, without
limitation, Specifications, and any other relevant documentation, will be attachments to
the applicable GMP Batch Work Order and/or incorporated in the Work Order by reference.
	 
	3.2.7	 	Each fully signed or otherwise mutually-approved Work Order will be subject to the terms of
this Agreement and will be incorporated herein and form a part of this Agreement.

     3.3 Quarterly FTE Estimates

At least ten (10) Business Days prior to the first day of each Calendar Quarter, the Joint
Development and Manufacturing Committee will determine, based on good faith input from both Tekmira
and Alnylam, a reasonable estimate of the number of FTEs that will be required to perform the
Supply Services called for in each of the Work Orders that is, or is to be, effective as to that
upcoming Calendar Quarter (each is the “Quarterly FTE Estimate” for that Work Order).

     3.4 Change Orders

	3.4.1	 	Neither Party will make any changes to the Specifications, Methods, procedures, processes,
Materials or Alnylam Equipment used under this Agreement or set forth in a Work Order, without
the other Party’s prior written approval, such approval not to be unreasonably withheld or

“Change Order”).
	 
	3.4.3	 	Change Orders with respect to Other Supply Services Work Orders may be proposed and adopted
from time to time in the same manner as described in Section 3.2.3 for the proposal and
adoption of Other Supply Services Work Orders.
	 
	3.4.4	 	Change Orders with respect to non-GMP Batch Work Orders (“non-GMP Batch Change Orders”),
consistently with Section 3.2.4, may take the form, may be adopted, and shall include the
elements, determined to be appropriate from time to time by the Joint Development and
Manufacturing Committee, subject to any financial limits on the signing authority of the
Parties’ representatives on the Joint Development and Manufacturing Committee based on such
Party’s internal controls.
	 
	3.4.5	 	For each proposed Change Order with respect to GMP Batch Work Order (a “GMP Batch Change
Order”) submitted by Alnylam, Tekmira will, within the longer of (a) four (4) Business Days of
written notice of such Change Order from Alnylam, or (b) such time as may be required for
Tekmira to obtain necessary information from Third Party suppliers with respect to such
proposed Change Order, but not in excess of twelve (12) Business Days, indicate in writing to
Alnylam (i) whether such GMP Batch Change Order is necessary or feasible, (ii) to what extent,
if any, such GMP Batch Change Order alters the time frame, or any other parameters of
Tekmira’s performance of the Supply Services, and (iii) what effect, if any, Tekmira believes
the implementation of such GMP Batch Change Order would have on the Price of the affected
Supply Services, expressed as a revised GMP Batch Work Order Estimated Price for such Work
Order (the “Adjusted GMP Batch Work Order Estimated Price”). For each GMP Batch Change Order
initiated by Tekmira, Tekmira will indicate the information described in clauses (i) through
(iii) above as part of its written notice to Alnylam of the proposed Change Order. If

- 12 -

 

	 	 	Alnylam accepts the terms of such GMP Batch Change Order in writing, then the relevant GMP
Batch Work Order will be deemed amended to reflect those changes set forth in such Change
Order. No GMP Batch Change Order will be effective unless and until it has been agreed to
and signed by authorized representatives of both Parties. Neither Party will be obligated
to enter into any GMP Batch Change Order, but each Party hereby agrees to be reasonable and
to use good faith in its considerations of draft GMP Batch Change Orders submitted by the
other Party; provided, however, that nothing contained herein shall require either Party to
accept any Change Order which contains provisions which are contrary to the terms of this
Agreement.
	 
	3.4.6	 	Each fully signed or otherwise mutually-approved Change Order will be subject to the terms
of this Agreement and will be incorporated herein and form a part of this Agreement.

to the account specified by Tekmira. All undisputed balances remaining unpaid thirty (30) days
after the date due for payment will bear interest at the rate of the greater of one percent (1%)
per month or the prime rate plus 1%, compounded annually.

     4.3 Audit

	4.3.1	 	Access. Upon the written request of Alnylam and not more than once in each Calendar Year,
Tekmira shall permit an independent certified public accounting firm of nationally recognized
standing selected by Alnylam and reasonably acceptable to Tekmira, at Alnylam’s expense except
as set forth below, to have access during normal business hours to such of the records of
Tekmira as may be reasonably necessary to verify the accuracy of the amounts billed to Alnylam
by Tekmira pursuant hereto, including FTEs (including Third Party Management Work), Materials
Costs and Third Party Costs, for any Calendar Year ending not more than thirty-six (36) months
prior to the date of such request, for the sole purpose of verifying the basis and accuracy of
payments made under this Article 4.
	 
	4.3.2	 	Discrepancies; Default Interest. If such accounting firm identifies a discrepancy made
during such period, the appropriate Party shall pay the other Party the amount of the
discrepancy within twenty (20) Business Days of the date Alnylam delivers to Tekmira such

writing. Such written report shall be binding upon the Parties. The fees charged by such
accounting firm shall be paid by Alnylam, unless such discrepancy represents an overpayment by
Alnylam of more than the lesser of [**] or [**] of the total amounts due hereunder in any
Calendar Year, in which case such fees shall be paid by Tekmira. Unless an audit for such
Calendar Year has been commenced upon the expiration of thirty-six (36) months following the
end of such Calendar Year, the calculation of payments payable with respect to such Calendar
Year shall be binding and conclusive upon both Parties, and each Party shall be released from
any further liability or accountability with respect to royalties and other payments for such
Calendar Year.

GMP Batch Forecast of Alnylam’s anticipated requirements for GMP Batch production under this
Agreement, covering the Calendar Quarter in which such GMP Batch Forecast is so delivered and the
following seven (7) Calendar Quarters. Such GMP Batch Forecast shall not constitute a Work Order
for any Supply Services, but the requirements stated in each GMP Batch Forecast for the first two
Calendar

- 15 -

 

Quarters covered by such GMP Batch Forecast shall: (a) constitute Alnylam’s binding commitment to
place GMP Batch Work Orders for Supply Services to produce such volumes for delivery during such
two Calendar Quarters (it being understood that Alnylam will have submitted GMP Batch Work Orders
for the first of such Calendar Quarter during the preceding Calendar Quarter, consistent with
Section 5.2.1); and (b) constitute Tekmira’s binding commitment to provide such Supply Services
under mutually-agreed GMP Batch Work Orders; provided, however, that Tekmira will use its
commercially reasonable efforts to meet Alnylam’s needs.

     5.2 Lead Time for Work Orders

	5.2.1	 	Alnylam will provide Tekmira a draft GMP Batch Work Order with sufficient lead time to
enable both Parties to have clarified the terms of and have duly executed such GMP Batch Work
Order at least ninety (90) days before the first date of Supply Services scheduled under such
GMP Batch Work Order, or such shorter amount of time as the Parties may agree, working through
the Joint Development and Manufacturing Committee or otherwise, it being agreed that both
Parties will exert commercially reasonable efforts to shorten lead times where practicable.
Alnylam will provide Tekmira draft non-GMP Batch Work Orders and Other Supply Services Work
Orders allowing for reasonable lead times deemed to be sufficient by action of the Joint
Development and Manufacturing Committee.
	 
	5.2.2	 	Each Work Order will be governed by the terms of this Agreement and none of the terms or
conditions of either Party’s acknowledgement forms or any other forms will be applicable,
except those specifying the matters set forth in Sections 3.2 or 3.4.
	 
	5.2.3	 	Notwithstanding the foregoing, Alnylam reserves the right, on one (1) week’s prior written
notice to Tekmira, to suspend a Work Order in the event of a Serious Adverse Drug Event as
defined under Applicable Laws or a modification of Alnylam’s Product development schedule. If
such suspension occurs, Alnylam will reimburse Tekmira for any non-cancellable costs incurred
up to and including the date of such suspension and will pay Tekmira for that portion of the
Price that is allocable (on the basis of percentage of completion) to the Supply Services
conducted under the affected Work Order to the date of the suspension, upon presentation of
satisfactory evidence that such Supply Services were conducted, all in accordance with Article
4.

     5.3 Scheduling and Capacity

	5.3.1	 	Alnylam acknowledges that the late delivery of sufficient quantity and quality of any
Alnylam Materials and/or documentation by Alnylam to Tekmira may result in a delay in the
provision of Supply Services. In the event of the late delivery of any Alnylam Materials
and/or documentation for which Tekmira is not responsible, (a) Tekmira will use commercially
reasonable efforts to maintain the schedule set forth in the affected Work Order(s) and will
notify Alnylam of any necessary change to such schedule, and (b) the Parties will enter into a
Change Order to revise such schedule on mutually agreed terms. In no event shall Tekmira’s
entitlement to compensation or status as exclusive manufacturer be prejudiced by Alnylam’s
late delivery of Alnylam Materials and/or documentation.
	 
	5.3.2	 	Tekmira will maintain sufficient capacity in the Facilities to enable it to provide Supply
Services under GMP Batch Work Orders during the first two Calendar Quarters covered by
Alnylam’s most recent GMP Batch Forecast. Tekmira will give Alnylam reasonable prior written
notice of any shutdown of Facilities (that is not a regularly scheduled occurrence of which
Alnylam is already aware) or of any event that may prevent Tekmira from or delay Tekmira in
providing such Supply Services to Alnylam.

     5.4 Post-2011 Annual FTE Estimates

	5.4.1	 	On or before December 1, 2011, the Joint Development and Manufacturing Committee will
determine an estimated number of FTEs (the “Annual FTE Estimate”) anticipated to be required
for Supply Services under this Agreement during 2012, based on the then most-current GMP Batch
Forecast for each of the Calendar Quarters in 2012, and the Parties’ then most-current
available information with respect to other Supply Services (whether with respect to non-GMP
Batches or otherwise) anticipated to be required by Alnylam and to be supplied by Tekmira
during 2012 under this Agreement. For clarity, such estimate is for planning purposes only
and shall not constitute a binding obligation of either Party.
	 
	5.4.2	 	Similarly, the Joint Development and Manufacturing Committee will determine an Annual FTE
Estimate for each subsequent calendar year during the Term, and will do so on or before
December 1 of the preceding year.

prior written consent from, Alnylam or such shorter notice as is otherwise mutually agreed between
the Parties. Such consent will not be unreasonably withheld or delayed (it being understood and
agreed that Alnylam may withhold consent pending satisfactory completion of a quality assurance
audit and/or regulatory impact assessment of the new location or additional facility, as the case
may be). In addition, Alnylam may elect to permit Tekmira to proceed with use of such changed or
additional facility prior to completion of an audit, but such use will be subject to Alnylam’s
right to require Tekmira to cease use of any such facility if such facility does not pass Alnylam’s
audit.

     6.3 Personnel

	6.3.1	 	Unless otherwise set forth in this Article or in a Work Order, Tekmira will furnish all
personnel, Tekmira Material and supervision necessary to perform the Supply Services. Tekmira

Facilities (“Tekmira Equipment”). If certain Tekmira Equipment is not deemed suitable by
Alnylam, Alnylam shall have the option of providing substitute or supplementary equipment
approved by Tekmira (which approval shall not be unreasonably withheld), in which case such
equipment supplied by Alnylam shall be deemed “Alnylam Equipment” for the purposes of this
Agreement.
	 
	6.4.2	 	All Alnylam Equipment placed in Tekmira’s possession will at all times remain the property
of Alnylam, will be visibly marked as the property of Alnylam, and will be used exclusively
for the performance of Supply Services pursuant to this Agreement. Tekmira shall ensure that
such Alnylam Equipment remains free and clear of any liens or encumbrances. Upon termination
of this Agreement or upon Alnylam’s written request, Tekmira will forthwith return to Alnylam
all Alnylam Equipment or permit Alnylam to enter onto Tekmira’s premises to retrieve all
Alnylam Equipment.
	 
	6.4.3	 	Alnylam will be responsible for the cost of the initial calibration of such Alnylam
Equipment upon delivery of same to Tekmira, and the cost of any maintenance, qualification,
and calibration, as applicable, of Alnylam Equipment will be apportioned between the Parties
in Work Orders. Tekmira shall not be required to provide or pay for spare parts for Alnylam
Equipment. To the extent Alnylam provides spare parts for Alnylam Equipment, such spare parts

established by the Joint Development and Manufacturing Committee. Tekmira will also be responsible
for ensuring that all such qualifications and/or validations have been performed in the case of all
other Facilities or equipment, to the extent involved in the Manufacture of any GMP Batch. Tekmira
will also be responsible for ensuring that all such validated processes to the extent involved in
the Manufacture of any GMP Batch are carried out in accordance with their terms.

     6.6 Licenses and Permits

Tekmira will be responsible for obtaining, at its expense, the Facilities and any licenses or
permits and regulatory and government approvals necessary for the operation and use of the
Facilities as pharmaceutical manufacturing facilities generally (i.e., without specific regard to
the Products or the performance of Supply Services by Tekmira under this Agreement). Where any
such licenses, permits or approvals are required specifically for the performance of Supply
Services by Tekmira under this Agreement which would not otherwise be required by Tekmira, the
expense thereof shall be treated as part of Tekmira’s Third Party Costs for purposes of determining
the Price.

shall provide a replacement Batch, which will be treated for purposes of Article 4 as if it
were a new Batch called for under the applicable Work Order, and the aggregate Price for the
Supply Services provided with respect to the failed At-Risk Batch and with respect to such
replacement Batch will equal the sum of the amounts called for under Article 4 for both such
Batches; provided, however, that in the event that [**], then such At-Risk Batch will (a) be
subject to Section 8.4.4., and will be treated as a Disputed Batch which is not an At-Risk
Batch for purposes of Section 8.4.4 and (b) be an At-Risk Batch for all other purposes.
	 
	8.4.4	 	If such independent laboratory finds, or the Parties otherwise agree, that a Disputed Batch
(other than an At-Risk Batch) failed to meet Specifications when delivered to Alnylam or its
designee, whether or not due to Tekmira’s negligence or a breach by Tekmira of its obligations
under this Agreement, and Alnylam makes no use of the Disputed Batch in pre-clinical or
clinical testing, Tekmira shall provide a replacement Batch, and the aggregate Price for the
Supply Services provided with respect to the failed Batch and to be provided with respect to
such replacement Batch shall equal the Price for the failed Batch plus the Materials Cost and
Third Party Costs attributable to the replacement Batch, it being understood and agreed that
Alnylam will supply and bear the costs of all Alnylam Materials to be incorporated into the
replacement Batch and Tekmira will bear the other costs incurred as a result of having to run
such replacement Batch, and, in addition, Tekmira shall, pay the fees and costs incurred in
connection with the testing conducted by the independent laboratory; provided, however, that
Alnylam shall pay the costs of the independent laboratory with respect to the testing of any
non-GMP Batch regardless of the findings of such independent laboratory .
	 
	8.4.5	 	If such independent laboratory finds, or the Parties otherwise agree, that the Disputed
Batch failed to meet Specifications due to handling, events or other causes following delivery
of such Batch to Alnylam or its designee, Tekmira shall provide a replacement Batch, which
will be treated for purposes of Article 4 as if it were a new Batch called for under the
applicable Batch Work Order, and the aggregate Price for the Supply Services provided with
respect to the failed Batch and with respect to such replacement Batch will equal the sum of
the amounts called for under Article 4 for both such Batches.

	 	 	 	GMP Batch price quote is the same or better than the Third Party’s quote, Alnylam
shall continue to obtain its supply of such Bulk Product from Tekmira in accordance
with this Agreement.

	 	 	For purposes of clarity, Tekmira’s obligations to qualify a Back-Up Manufacturer and to
perform Technical Transfer will be performed in a reasonable timeframe that is consistent
with the timeframes established by the Joint Development and Manufacturing Committee for the
product development program for such Product, taking into account the need to qualify a
Back-Up Manufacturer and Manufacture Product for such first Phase III Study sufficiently in
advance of the initiation of such Phase III Study with respect to such Product in order that
Alnylam will have sufficient supplies of such Product for commencement of such Phase III
Study without delay.

	11.1.2	 	Alnylam and Tekmira shall agree from time to time on one or more additional suppliers of
Bulk Product (each a “Back-Up Manufacturer”), such that at all times, there is at least one
primary manufacturer and at least one Back-Up Manufacturer. Initially, if qualified, [**]
shall serve as a Back-Up Manufacturer acceptable to both Parties. Alnylam shall have the
right to propose such Back-Up Manufacturer(s) and Tekmira shall have the right to consent to
such Back-Up Manufacturer(s), which consent shall not be unreasonably withheld or delayed.
[**].
	 
	11.1.3	 	Subject to Section 11.3, Tekmira shall promptly provide Technical Transfer to all such
Back-Up Manufacturer(s) to the extent required to accomplish the timely qualification of such
Back-Up Manufacturer(s). Within thirty (30) days after the Effective Date, Tekmira shall
deliver to Alnylam, for review and approval, a Work Order containing a project overview for
establishing and qualifying [**] as the initial Back-Up Manufacturer. This project overview
will include contract manufacturing organization targets, timelines, equipment requirements,
and both FTE and out-of-pocket expense estimates. As part of the qualification of such Back-Up
Manufacturer, Alnylam shall have the right to have such Back-Up Manufacturer Manufacture
Products in such amounts as may be necessary to ensure successful qualification of such
Back-Up Manufacturer and as may be necessary to maintain such qualification. For clarity,
qualification shall be deemed to have occurred if the Back-Up Manufacturer’s facility is
successfully audited (no critical deficiencies observed) by a Qualified Person (as such term
is defined by the relevant Regulatory Authorities) in the applicable countries within the
European Union. In addition, any manufacturing campaigns in excess of the minimum number of
Batches required to maintain such Back-Up Manufacturer for Bulk Product shall be performed by
Tekmira under Work Orders and this Agreement. In order to monitor Alnylam’s compliance with
this provision, Alnylam will provide Tekmira with an annual forecast and a written report,
certified by an officer of Alnylam, of the quantities of finished dosage form obtained by
Alnylam from all Back-Up Manufacturers.

	 	11.2	 	Methods Transfer

Subject to Section 11.3, Tekmira will provide to each of the Third Parties utilized by Tekmira in
the performance of the Supply Services, and to each Back-Up Manufacturer, the necessary training to
enable each of them to perform the Methods each of them is entrusted or expected to perform.
Tekmira will require each such Third Party and such Back-Up Manufacturer to provide Tekmira with
documentary evidence to confirm their incorporation of each Method into their respective change
control system and their successful performance of the new or revised Method. Such Method
transfers from Tekmira will be completed in accordance with protocols to be established between
Tekmira and each transferee.

	 	11.3	 	Technical Transfer

	11.3.1	 	Alnylam acknowledges and agrees that the transfer of Confidential Information and
Intellectual Property owned or controlled by Tekmira and necessary for the Manufacture of a
specific Product

- 28 -

 

	 	 	 	shall be used by the recipient of such Confidential Information and Intellectual Property
(be it Alnylam or a Back-Up Manufacturer, or otherwise) solely for the purpose of
Manufacturing the specific Product for which the Technical Transfer was conducted. For
avoidance of doubt Alnylam acknowledges and agrees that:

	 	(a)	 	the Confidential Information and Intellectual Property owned or controlled by
Tekmira and necessary for the Manufacture of a specific Product encompassed in any
Technical Transfer by Tekmira can only be used: (i) by the recipient of the Technical
Transfer, (ii) solely for the Manufacture or regulatory approval of the specific
Product which formed the subject of the Technical Transfer and not for any other
product (or Product), and (iii) where Alnylam is the recipient of any such Confidential
Information and Intellectual Property, [**];

	 	(b)	 	the transfer by Tekmira of Tekmira Confidential Information and Tekmira
Intellectual Property for the Manufacture of a specific Product does not grant to the
recipient of such Technical Transfer any right or license of any kind to conduct
further transfer of Tekmira Confidential Information and Tekmira Intellectual Property
to any Person, for any purpose; and

	 	(c)	 	prior to the provision of any Methods under Section 11.2 or of any Technical
Transfer or any other Tekmira Confidential Information and Tekmira Intellectual
Property to any Third Party, including without limitation an alternate supplier, such
Third Party shall be required to execute and deliver to Tekmira the written
agreement(s) of such Third Party to be bound by the foregoing provisions of this
Section 11.3.1 and by Article 14 of this Agreement, explicitly for the benefit of
Tekmira, which agreement(s) must be in form and substance reasonably acceptable to
Tekmira.

	11.3.2	 	Tekmira will perform each Technical Transfer in accordance with Technical Transfer protocols
to be established between Tekmira and each Back-Up Manufacturer, with Alnylam’s approval,
which approval shall not unreasonably withheld or delayed, all of which protocols and other
documentation arising from the performance Technical Transfer activities shall constitute the
Confidential Information of Tekmira.

	 	11.4	 	The Parties agree to negotiate in good faith at the appropriate time Tekmira’s
Manufacture of Alnylam’s requirements of the Bulk Product for Phase III Studies and
commercial sale if Tekmira or its Affiliate is qualified and capable of performing this
Manufacture in the appropriate timeframe; provided, however, that nothing in this Agreement
shall be deemed to be a binding obligation of either Party to enter into such a transaction.
	 
	 	11.5	 	As of the Effective Date, the Manufacturing Plan will terminate and be replaced by Work
Orders under this Supply Agreement.

Article 14

Confidentiality and Intellectual Property

	14.1	 	Non-Use and Non-disclosure of Confidential Information.
	 
	14.1.1	 	Each Party agrees that all Confidential Information of a Party that is disclosed by a Party
to the other Party (a) will not be used by the receiving Party except in connection with the

or an Affiliate of the receiving Party, without the prior written consent of the disclosing
Party. Notwithstanding the foregoing, the receiving Party will be entitled to use and
disclose Confidential Information of the disclosing Party which (i) was known by the receiving
Party or its Affiliates prior to its date of disclosure by the disclosing Party to the
receiving Party as demonstrated by legally admissible evidence available to the receiving
Party or its Affiliates, (ii) either before or after the date of the disclosure such
Confidential Information is lawfully disclosed to the receiving Party or its Affiliates by
sources other than the disclosing Party, (iii) either before or after the date of the

becomes published or otherwise part of the public domain through no fault or omission on the
part of the receiving Party or its Affiliates, (iv) is independently developed by or for the
receiving Party or its

- 33 -

 

	 	 	Affiliates without reference to or in reliance upon the Confidential Information as
demonstrated by legally admissible evidence available to the receiving Party or its
Affiliates, (v) is reasonably necessary to conduct clinical trials or to obtain regulatory
approval of the Products or for the prosecution and maintenance of patent rights, (vi) is
reasonably required in order for a Party to obtain financing or conduct discussions with
partners so long as such Third Party recipients are bound by an obligation of
confidentiality, or (vii) in the reasonable judgment of the disclosing Party is required to
be disclosed by the receiving Party to comply with applicable laws or regulations or legal
process, including without limitation by the rules or regulations of the United States
Securities and Exchange Commission or similar regulatory agency in a country other than the
United States or of any stock exchange or NASDAQ, provided that the receiving Party provides
prior written notice of such disclosure to the disclosing Party and takes reasonable and
lawful actions to avoid or minimize the extent of such disclosure.
	 
	 	 	If a Party is required by judicial or administrative process to disclose Confidential
Information that is subject to the non-disclosure provisions of this Section 14.1.1, such
Party shall promptly inform the other Party of the disclosure that is being sought in order
to provide the other Party an opportunity to challenge or limit the disclosure obligations.
Confidential Information that is disclosed by judicial or administrative process shall
remain otherwise subject to the confidentiality and non-use provisions of this Section
14.1.1, and the Party disclosing Confidential Information pursuant to law or court order
shall take all steps reasonably practical, including without limitation seeking an order of
confidentiality, to ensure the continued confidential treatment of such Confidential
Information. In addition to the foregoing restrictions on public disclosure, if either Party
concludes that a copy of this Agreement must be filed with the United States Securities and
Exchange Commission or similar regulatory agency in a country other than the United States,
such Party shall seek the maximum confidential treatment available under applicable law,
provide the other Party with a copy of this Agreement showing any sections as to which the
Party proposes to request confidential treatment, provide the other Party with an
opportunity to comment on any such proposal and to suggest additional portions of this
Agreement for confidential treatment, and take such Party’s reasonable comments into
consideration before filing this Agreement.
	 
	14.1.2	 	Each Party agrees that it will provide Confidential Information received from the other
Party solely to its employees, consultants and advisors, and the employees, consultants and
advisors of its Affiliates or Back-Up Manufacturers as applicable, who have a legitimate
business need to know and an obligation to maintain in confidence the Confidential Information
of the disclosing Party. The disclosing Party is liable for any breach of the non-disclosure
obligation of its consultants, advisors, Affiliates and Back-Up Manufacturers as applicable.
	 
	14.1.3	 	The Parties each acknowledge and recognizes the mutual interest in protecting business
interests and trade secret information. Consequently, except for disclosures permitted
pursuant to Section 14.1.1 and 14.1.2, either Party, its Affiliates, or their respective
employees or consultants wishing to make a publication or a disclosure to a Third Party
relating to the Product shall deliver to the other Party a copy of the proposed written
publication or an outline of an oral disclosure at least thirty (30) days prior to submission
for publication or presentation. The reviewing Party shall have the right (a) to propose
modifications to the publication or presentation for patent reasons, trade secret reasons or
business reasons, or (b) to request a reasonable delay in publication or presentation in order
to protect patentable information. If the reviewing Party requests a delay, the publishing
Party shall delay submission or presentation for a period of thirty (30) days to enable patent
applications protecting each Party’s rights in such information to be filed. Upon expiration
of such thirty (30) days, the publishing Party shall be free to proceed with the publication
or presentation. If the reviewing Party requests modifications to the publication or

- 34 -

 

	 	 	presentation, the publishing Party shall edit such
publication to prevent disclosure of trade secret or
proprietary business information prior to submission
of the publication or presentation. With respect to
any proposed publications or disclosures by
investigators or academic or non-profit

and ability (after using reasonable efforts) to do
so.

developed in the course of the activities conducted pursuant to this Agreement will be governed by
the terms and conditions of the Restated Tekmira LCA and Restated Protiva CLA.

	14.3	 	Injunctive Relief

Each Party acknowledges the competitive and technical value and the sensitive and confidential
nature of the Confidential Information and agrees that monetary damages alone will be inadequate to
protect the other Party’s interests against any actual or threatened material breach of Section
14.1 of this Agreement. Accordingly, each Party consents to the granting of specific performance
and injunctive or other equitable relief to the other Party in respect of any actual or threatened
breach of Article 11 and Section 14.1 of this Agreement, without proof of actual Damages. These
specific remedies are in addition to any other remedy to which the Parties may be entitled at law
or in equity.

- 35 -

 

	15.2	 	Indemnification by Tekmira
	 
	15.2.1	 	Tekmira agrees to indemnify, defend and hold Alnylam and its directors, officers, employees,
consultants and agents (“Alnylam Indemnities”) harmless from and against any Damages resulting

Party.

	15.4	 	LIMITATION OF LIABILITY

NEITHER PARTY HERETO WILL BE LIABLE FOR SPECIAL, INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES
ARISING OUT OF THIS AGREEMENT OR THE EXERCISE OF ITS RIGHTS HEREUNDER OR THEREUNDER, INCLUDING LOST

CONFIDENTIALITY AND NON-USE OBLIGATIONS IN ARTICLE 14. NOTHING IN THIS SECTION 15.4 IS INTENDED TO
LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY.

	15.5	 	Notice and Opportunity To Defend

Promptly after receipt by a Party hereto of notice of any claim which could give rise to a right to
indemnification pursuant to Sections 15.1 or 15.2, such Party (the “Indemnified Party”) will give
the other Party (the “Indemnifying Party”) written notice describing the claim in reasonable
detail. The failure of an Indemnified Party to give notice in the manner provided herein will not
relieve the Indemnifying Party of its obligations under this Section, except to the extent that
such failure to give notice materially prejudices the Indemnifying Party’s ability to defend such
claim. The Indemnifying Party will have the right, at its option, to compromise or defend, at its
own expense and by its own counsel, any such matter involving the asserted liability of the Party
seeking such indemnification. If the Indemnifying Party will undertake to compromise or defend any
such asserted liability, it will promptly (and in any event not less than ten (10) Business Days
after receipt of the Indemnified Party’s original notice) notify the Indemnified Party in writing
of its intention to do so, and the Indemnified Party agrees to cooperate fully with the
Indemnifying Party and its counsel in the compromise or defence against any

- 36 -

 

such asserted liability. All reasonable costs and expenses incurred in connection with such
co-operation will be borne by the Indemnifying Party. If the Indemnifying Party elects not to
compromise or defend the asserted liability, fails to notify the Indemnified Party of its election
to compromise or defend as herein provided, fails to admit its obligation to indemnify under this
Agreement with respect to the claim, or, if in the reasonable opinion of the Indemnified Party, the
claim could result in the Indemnified Party becoming subject to injunctive relief or relief other
than the payment of money damages that could materially adversely affect the ongoing business of
the Indemnified Party in any manner, the Indemnified Party will have the right, at its option, to
pay, compromise or defend such asserted liability by its own counsel and its reasonable costs and
expenses will be included as part of the indemnification obligation of the Indemnifying Party
hereunder. Notwithstanding the foregoing, neither the Indemnifying Party nor the Indemnified Party
may settle or compromise any claim over the objection of the other; provided however, that consent
to settlement or compromise will not be unreasonably withheld. In any event, the Indemnified Party
and the Indemnifying Party may participate, at their own expense, in the defence of such asserted
liability. If the Indemnifying Party chooses to defend any claim, the Indemnified Party will make
available to the Indemnifying Party any books, records or other documents within its control that

Article 16

General

	16.1	 	Assignment and Subcontracting

The rights and obligations covered hereunder are personal to each Party hereto and for this reason
this Agreement will not be assignable by either part in whole or in part, nor will either Party
subcontract any of its obligations hereunder without the prior written consent of the other Party;
provided however, that the restriction contained herein will in no way limit the rights of either
Party to assign or subcontract to any of its Affiliates, or to a party that acquires, by merger,
sale of assets or otherwise, all or substantially all of the business of such Party to which the
subject matter of this Agreement relates. This Agreement will be binding upon and will enure to
the benefit of the Parties hereto and to any permitted assignee or successor of either Party.
Subject to other provisions of this Section 16.1, if one Party validly assigns or subcontracts any
or all of its obligations hereunder, such assigning Party agrees to remain bound by all of its
responsibilities and obligations hereunder. Any and all assignments of this Agreement or any
interest herein not made in accordance with this Section 16.1 will be void ab initio.

	16.2	 	Amendment

This Agreement may be modified or amended only by written agreement of the Parties hereto.

	16.3	 	Captions

All section titles or captions contained in this Agreement and contained in any exhibit or appendix
referred to herein or annexed to this Agreement are for convenience only, will not be deemed a part
of this Agreement and will not affect the meaning or interpretation of this Agreement.

	16.4	 	Construction

This Agreement will be deemed to have been drafted by both Tekmira and Alnylam after extensive
negotiations and will not be construed against either Party as the draftsperson hereof.

	16.5	 	Counterparts

This Agreement may be executed in any number of counterparts, each of which will be deemed an
original but all of which together will constitute a single instrument.

	16.6	 	Dispute Resolution

     16.6.1 Disputes. The Parties shall negotiate in good faith and use reasonable efforts to
settle any dispute, controversy or claim arising from, or related to, this Agreement or to the
breach hereof (collectively, “Dispute”). In the event that the Executive Officers cannot reach an
agreement regarding a Dispute within thirty (30) days after submission to them for resolution and a
Party wishes to pursue the matter, each such Dispute that is not an “Excluded Claim” shall
be finally resolved by binding arbitration in accordance with the Commercial Arbitration Rules and
Supplementary Procedures for Large Complex Disputes of the American Arbitration Association
(“AAA”) and Section 16.6.2 below, and judgment on the arbitration award may be entered in
any court having jurisdiction thereof. As used in this Section 16.6, the term “Excluded Claim”
shall mean a dispute that concerns (a) the validity or infringement of a patent, trademark or
copyright, or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not
statutory.

     16.6.2 Arbitration. The arbitration shall be conducted by a panel of three (3) persons
experienced in the pharmaceutical business who are independent of both Parties and neutral with
respect to the Dispute presented for arbitration. Within thirty (30) days after initiation of
arbitration, each Party shall select one person to act as arbitrator and the two Party-selected
arbitrators shall select a third arbitrator within thirty (30) days of their appointment. If the
arbitrators selected by the Parties are unable

- 38 -

 

or fail to agree upon the third arbitrator, the third arbitrator shall be appointed by the
AAA. The place of arbitration shall be Chicago, Illinois, USA, and all proceedings and
communications shall be in English. Either Party may apply to the arbitrators for interim
injunctive relief until the arbitration award is rendered or the controversy is otherwise resolved.
Either Party also may, without waiving any remedy under this Agreement, seek from any court having
jurisdiction any injunctive or provisional relief necessary to protect the rights or property of
that Party pending the arbitration award. The arbitrators shall have no authority to award
punitive or any other type of damages not measured by a Party’s compensatory damages. Each Party
shall bear its own costs and expenses and attorneys’ fees, and the Party that does not prevail in
the arbitration proceeding shall pay the arbitrators’ and any administrative fees of arbitration.
Except to the extent necessary to confirm an award or as may be required by law, neither a Party
nor an arbitrator may disclose the existence, content, or results of an arbitration without the
prior written consent of both Parties. In no event shall an arbitration be initiated after the
date when commencement of a legal or equitable proceeding based on the Dispute, controversy or
claim would be barred by the applicable Massachusetts statute of limitations.

	 	(i)	 	The Parties agree that, in the event of a Dispute over the nature or quality of
performance under this Agreement, neither Party may terminate this Agreement until
final resolution of the Dispute through arbitration or other judicial determination.
The Parties further agree that any payments made pursuant to this Agreement pending
resolution of the Dispute shall be refunded promptly if an arbitrator or court
determines that such payments are not due.

	 	(ii)	 	The Parties hereby agree that any disputed performance or suspended
performances pending the resolution of the arbitration that the arbitrator determines
to be required to be performed by a Party must be completed within a reasonable time
period following the final decision of the arbitrator.

	 	(iii)	 	The Parties agree that the decision of the arbitrator shall be the sole,
exclusive and binding remedy between them regarding determination of the matters
presented to the arbitrator.

	16.6.3	 	Judgment upon the award may be entered in any court having jurisdiction, or application may
be made to such court for judicial acceptance of the award and/or an order of enforcement as
the case may be.
	 
	16.6.4	 	Either Party will be free to submit any Dispute relating to an Excluded Claim to any court
having jurisdiction over the Parties and the subject matter of the Dispute and to seek such
relief and remedies as are available in that court.
	 
	16.7	 	Entire Agreement

This Agreement and its appendices constitute the entire agreement between the Parties with respect
to the subject matter hereof and supersede all prior agreements or understandings of the Parties
relating thereto, including without limitation the MSA, but not including (unless otherwise
explicitly stated in this Agreement) the Restated Tekmira LCA or the Restated Protiva CLA.
Sections 5.3(a) and 5.3(b) are hereby stricken from the Restated Tekmira LCA, and 5.3(a) thereof
shall be renumbered to be 5.3 (and the heading of such section shall be “Phase III and Commercial
Supply.”)

	16.8	 	Force Majeure

If either Party is prevented from complying, either totally or in part, with any of the terms or
provisions set forth herein by reason of force majeure, including, by way of example and not of
limitation, fire, flood, explosion, storm, riot, war, rebellion, accidents, acts of God, acts of
governmental agencies or

- 39 -

 

instrumentalities, or any other cause or externally induced casualty beyond its reasonable control,
whether similar to the foregoing contingencies or not, said Party will provide written notice of
same to the other Party. Said notice will be provided within seven (7) days of the occurrence of
such event and will identify the requirements of this Agreement or such of its obligations as may
be affected, and to the extent so affected, said obligations will be suspended during the period of
such disability. The Party prevented from performing hereunder will use commercially reasonable
efforts to remove such disability and will continue performance of the affected obligations
whenever such causes are removed provided that the Party will throughout the period of disability
continue performance of the non-affected obligations. The Party so affected will give to the other
Party a good faith estimate of the continuing effect of the force majeure condition and the
duration of the affected Party’s non-performance. If any raw materials, facility systems or
capacity is used for both the affected Product and any other products or purposes, any necessary
allocation will be made, on a substantially pro rata basis, as between Tekmira’s needs (including
those of any Affiliate of Tekmira), Alnylam’s needs and the needs of any other Party to whom
Tekmira has firm contractual obligations. If the period of any previous actual non-performance of
Tekmira because of Tekmira force majeure conditions plus the anticipated future period of Tekmira
non-performance because of such conditions will exceed an aggregate of one hundred eighty (180)
days within any twenty-four (24) month period, Alnylam may terminate this Agreement by notice to
Tekmira and any orders for Product then outstanding will be deemed cancelled. If the period of any
previous actual non-performance of Alnylam because of Alnylam force majeure conditions plus the
anticipated future period of Alnylam non-performance because of such conditions will exceed an
aggregate of one hundred eighty (180) days within any twenty-four (24) month period, Tekmira may
terminate this Agreement by notice to Alnylam and any orders for Product then outstanding will be
deemed cancelled. When such circumstances as those contemplated herein arise, the Parties will
discuss in good faith, what, if any, modification of the terms set forth herein may be required in
order to arrive at an equitable solution.

	16.9	 	Further Assurances

The Parties will both execute and deliver such further instruments and do such further acts as may
be required to implement the intent of this Agreement.

	16.10	 	Governing Law

This Agreement will be governed and construed in accordance with the laws of the State of Delaware,
U.S.A.; provided that (i) matters of intellectual property law concerning the existence,
validity, ownership, infringement or enforcement of intellectual property shall be determined in
accordance with the national intellectual property laws relevant to the intellectual property in
question, and (ii) the application of the 1980 United Nations Convention on Contracts for the
International Sale of Goods is expressly excluded from this Agreement.

	16.11	 	Independent Contractors

This Agreement will not constitute or give rise to any employer-employee, agency, partnership or
joint venture relationship among or between the Parties, and each Party’s performance hereunder is
that of a separate, independent entity.

	16.12	 	No Implied Rights

Except as otherwise expressly provided in this Agreement between the Parties, nothing in this
Agreement will be deemed or implied to be the grant by one Party to the other of any right, title
or interest in the Product, any Confidential Information, trade mark, trade dress or any other
Intellectual Property or any other proprietary right of the other.

- 40 -

 

	16.13	 	No Joint Venture

Nothing contained herein will be deemed to create any joint venture or partnership between the
Parties hereto, and, except as is expressly set forth herein, neither Party will have any right by
virtue of this Agreement to bind the other Party in any manner whatsoever.

	16.14	 	No Third-Party Rights

No provision of this Agreement will be deemed or construed in any way to result in the creation of
any rights or obligation in any Person not a Party to this Agreement.

	16.15	 	No Waiver; Remedies

No delay on the part of Tekmira or Alnylam in exercising any right, power or privilege hereunder
will operate as a waiver thereof, nor will any waiver on the part of either Tekmira or Alnylam of
any right, power or privilege hereunder operate as a waiver of any other right, power or privilege
hereunder nor will any single or partial exercise of any right, power or privilege hereunder
preclude any other or further exercise thereof or the exercise of any other right, power or
privilege hereunder.

	16.16	 	Notices

All notices or other communications required or permitted to be given hereunder will be in writing
and will be deemed to have been duly given if delivered by hand, prepaid telex, cable, telegram or
facsimile and confirmed in writing, courier service, or mailed first class, postage prepaid, by
registered or certified mail, return receipt requested (mailed notices and notices sent by telex,

provincial or foreign authorities, as determined in good faith by the disclosing Party. Where

or know-how, patentable or otherwise, that are necessary or useful for Kyowa Hakko to perform its
obligations under this Agreement. Such Third Party collaborations shall not conflict with the
terms and conditions of this Agreement. In the event that any such Third Party collaborations are
contemplated in connection with the Development Plan, the JSC shall review, subject to Third Party
confidentiality obligations, such Third Party collaborations in advance of entering into such Third
Party collaborations, and Kyowa Hakko shall notify Alnylam in writing of each such Third Party
collaboration entered into by Kyowa Hakko. Kyowa Hakko shall use good faith efforts to ensure
that, to the extent possible, all such Third Party collaborations shall provide that any and all
data and results, discoveries and inventions, whether patentable or not, arising out of the Third
Party collaboration may be used by Alnylam and its Related Parties and shall include
confidentiality and non-use provisions that are no less stringent than those set forth in Article 8
of this Agreement. In addition, Kyowa Hakko shall use good faith efforts to obtain a right to
sublicense to Alnylam and its Related Parties any intellectual property arising out of the Third
Party collaboration. For clarity, such Third Party collaboration shall not include contract
research or contract manufacturing organizations set forth in Section 2.8.1 or the Sublicensee of
the Licensed Product.

     (b) Alnylam Collaborations. Nothing contained in this Agreement will prevent or
prohibit Alnylam from entering into collaborations with Third Parties that provide technology,
information, data or know-how, patentable or otherwise, that are necessary or useful for Alnylam to
Develop,

16

 

Manufacture, or Commercialize the Licensed Product, Replacement Products or Successor Products
in the Alnylam Territory or otherwise perform its obligations under this Agreement.

     2.9 Replacement Product. Alnylam will promptly notify Kyowa Hakko in writing (a
“Replacement Product Notice”) if, at any time during the Term prior to the First Commercial Sale of
the Lead Product in the Alnylam Territory, Alnylam terminates the Development of the Lead Product
and elects, in its sole discretion, to commence Development of another RSV Product (the
“Replacement Product”) in the Alnylam Territory. Effective upon such notice (a) the Development
Collaboration shall terminate with respect to the Lead Product, but will continue with respect to
the Replacement Product, and the JSC will promptly update the Development Plan accordingly, (b) all
references to the Licensed Product in this Agreement will no longer include the Lead Product but
will instead include the Replacement Product, and (c) Kyowa Hakko’s license rights with regard to
the Lead Product will automatically terminate, unless Alnylam consents in writing to the
continuation of such licenses under this Agreement with respect to the Lead Product (which consent
shall not be unreasonably withheld or delayed). For clarity, this provision may be applied if
Alnylam terminates the Development of a Replacement Product, and commences the Development of a
further Replacement Product.

     2.10 Successor Product Option.

     (a) Alnylam will promptly notify Kyowa Hakko in writing (“Successor Product Notice”) if, at
any time during the Term after the First Commercial Sale of the Licensed Product in the Kyowa Hakko
Territory, Alnylam Initiates the first Phase III Study of an RSV Product other than the Lead
Product or the Replacement Product in the Alnylam Territory (the “Successor Product”). If the
Successor Product could reasonably be expected to be launched in the Kyowa Hakko Territory prior to
the end of the Expiry Period (defined below), then Alnylam hereby grants to Kyowa Hakko an option
to obtain an exclusive license under the Alnylam Technology to Develop and Commercialize the
Successor Product in the Field in the Kyowa Hakko Territory (the “Successor Product Option”).

     (b) The Successor Product Notice will contain (i) the chemical composition of the Successor
Product and (ii) such additional information as Kyowa Hakko may reasonably require in order to
evaluate and decide whether to exercise the Successor Product Option. Kyowa Hakko shall have a
period of [**] days after the date of the Successor Product Notice (“Successor Product Option
Period”) in which to exercise the Successor Product Option by written notice to Alnylam (“Successor
Product Option Notice”). Upon Kyowa Hakko giving a Successor Product Option Notice to Alnylam (the
“Successor Product Option Exercise Date”), the Parties will enter into a definitive license
agreement in accordance with the next sentence for an exclusive license under the Alnylam
Technology to Develop and Commercialize the Successor Product in the Field in the Kyowa Hakko
Territory (the “Successor Product License”) in good faith for a period not to exceed [**] days (or
such other period as the Parties may agree in writing) (“Negotiation Period”). The terms and
conditions of such definitive license agreement will be negotiated in good faith by the Parties,
but will be substantially similar to the terms of this Agreement, except that such definitive
license agreement will not include any terms and conditions relating to any subsequent Successor
Product Option, will include the Parties’ agreement to [**] royalties payable under Alnylam
In-Licenses of delivery technologies, and the financial terms will be based on the following terms:

17

 

	 	(i)	 	If the Successor Product could reasonably be expected to achieve commercial
launch in the Kyowa Hakko Territory within [**] years prior to the later of (x) the
expiration of the Term and (y) the expiration of all grants of marketing exclusivity by
a Regulatory Authority in the Kyowa Hakko Territory (such [**]year period, the “Expiry
Period”), then the financial terms of the Successor Product License will include
milestone fees that do not exceed [**] percent ([**]%) of each of the Development and
sales milestone fees set forth in Sections 7.2(a) and 7.3 of this Agreement;
	 
	 	(ii)	 	If the Successor Product could reasonably be expected to achieve commercial
launch in the Kyowa Hakko Territory prior to the commencement of the Expiry Period,
then [**] upfront, Development or sales milestones shall be payable by Kyowa Hakko to
Alnylam; and
	 
	 	(iii)	 	In any case, Kyowa Hakko shall pay Alnylam Royalties on net sales of such
Successor Product in the Kyowa Hakko Territory calculated as set forth in Section 7.4
of this Agreement.

     (c) If Kyowa Hakko does not deliver a Successor Product Option Notice to Alnylam within the
Successor Product Option Period, or if despite the good faith efforts of each Party, the Parties
fail to execute a definitive agreement for the Successor Product prior to the expiration of the
Negotiation Period, then Alnylam shall be free to Develop, Manufacture and Commercialize the
Successor Product in the Kyowa Hakko Territory, either on its own or with one or more Third
Parties; provided, however, that if the Parties have made a good faith effort but
failed to conclude such negotiations within the Negotiation Period and both Parties reasonably
believe that such negotiations may be successfully completed within a reasonable amount of
additional time, then the Parties may mutually agree to extend the Negotiation Period accordingly;
and provided, further, however, that Alnylam will not, without Kyowa
Hakko’s prior written consent not to be unreasonably withheld or delayed, either on its own or with
one or more Third Parties, launch the Successor Product for commercial sale in the Kyowa Hakko
Territory until the commencement of the Expiry Period.

     3. COLLABORATION MANAGEMENT

     3.1 Joint Steering Committee. The Parties hereby establish a committee to facilitate
the Collaboration as follows:

     3.1.1 Composition of the Joint Steering Committee. The Collaboration shall be

For purposes of clarity, the JSC shall not have the authority to modify the terms of this
Agreement.

     3.2 Appointment of Subcommittees, Project Teams and Collaboration Managers. The JSC
shall be empowered to create such subcommittees of itself and project teams as it may deem
appropriate or necessary. Each such subcommittee and project team shall report to the JSC, which
shall have authority to approve or reject recommendations or actions proposed thereby subject to
the terms of this Agreement. Each Party shall also designate a “Collaboration Manager.” The
Collaboration Managers will be responsible for the day-to-day coordination of the Collaboration and
will serve to facilitate communication between the Parties. Each Party may change its designated
Collaboration Manager from time to time upon written notice to the other Party.

19

 

     3.3 Reports and Minutes. Each Party shall prepare and deliver to the JSC, by no later

achievement by Alnylam of any milestone event set forth in Section 7.2. Each Party will provide
the members of the JSC with written copies of all materials they intend to present at a JSC
meeting. The JSC may also request at any time specific data or information related to Collaboration
activities or that a written report be prepared in advance of any meeting summarizing certain
material data and information arising out of the conduct of the Collaboration activities and the
Party or appropriate committee to whom such request is made shall promptly provide to the other
Party or JSC such report, data or information. A secretary shall be appointed for each meeting and
shall prepare minutes of the meeting, which shall provide a description in reasonable detail of the
discussions held at the meeting and a list of any actions, decisions or determinations approved by
the JSC.

     3.4 Decision-Making. The JSC shall attempt to resolve any and all disputes relating
to the Collaboration by consensus. If the JSC is unable to reach a consensus with respect to a
dispute, then the dispute shall be submitted to escalating levels of Alnylam and Kyowa Hakko senior
management for review. If such dispute cannot be resolved despite escalation, then the Chief
Executive Officers of Alnylam and Kyowa Hakko shall attempt to resolve such dispute. In the event
that the Chief Executive Officers cannot reach an agreement regarding such dispute within [**] days
after submission to them for resolution, then:

     (a) if the dispute is one over which the JSC has authority pursuant to Section 3.1, then Kyowa
Hakko shall have the final decision-making authority; provided, however, that Kyowa
Hakko (x) has no final decision-making authority over the Development or Commercialization of the
Licensed Product in the Alnylam Territory or the Manufacture of the Licensed Product by Alnylam,
(y) may not conduct, sponsor, fund or otherwise support a Clinical Study or Post-Approval Study of
the Licensed Product that would materially and adversely affect the Development or
Commercialization of the Licensed Product in the Alnylam Territory, without Alnylam’s prior written
consent; provided however, that Alnylam will consider in good faith any Clinical
Study design required by the Regulatory Authority in order to obtain Regulatory Approval in Japan
and will work diligently with Kyowa Hakko to identify Clinical Study designs which meet such
requirements in a way that does not materially and adversely affect the Development and
Commercialization of the Licensed Product in the Alnylam Territory, and (z) may not exercise its
final decision-making authority (A) to require Alnylam to use other than Commercially Reasonable
Efforts to perform its obligations under the Collaboration, (B) to require Alnylam to perform any
activities for which it is not responsible under this Agreement, (C) to require Alnylam to take or
fail to take any action that would violate any applicable law, rule or regulation or any agreement
with any Third Party or infringe the intellectual property rights of Third Parties, (D) over any
[**] conducted by Alnylam, or (E) to expand or narrow the responsibilities of the JSC; and

     (b) with respect to all other disputes between the Parties, the dispute resolution provisions
of Section 12.11 shall apply.

     3.5 Voting. With respect to decisions of the JSC, the representatives of each Party
shall have collectively one vote on behalf of such Party. For each meeting of the JSC, at least

representatives of each Party shall constitute a quorum. Action on any matter may be taken at
a meeting, by teleconference, videoconference or by written agreement.

     3.6 Dissolution of JSC. The JSC shall be dissolved upon the First Commercial Sale of
the Licensed Product in the Kyowa Hakko Territory; provided, that after the [**]

     4.2 Joint Commercialization Team. Commencing with the initiation of the first Phase
III Study of the Licensed Product, the Parties will establish a joint commercialization team
(“JCT”) to coordinate the global Commercialization of the Licensed Product. The provisions of
Sections 3.1.1, 3.1.2 and 3.1.3 relating to the operation of the JSC shall also apply to the JCT;

For purposes of clarity, the JCT shall not have the authority to modify the terms of this
Agreement.

     4.3 Regulatory Approvals. Except as may be required for Alnylam to perform its
obligations under this Agreement, Kyowa Hakko (or its Related Parties) shall be the holder of all

     4.5 Advertising and Promotional Materials. Kyowa Hakko will be responsible for the
creation, preparation, production, reproduction and filing with the applicable Regulatory
Authorities, of relevant written sales, promotion and advertising materials relating to the
Licensed Product (“Promotional Materials”) for use in the Kyowa Hakko Territory. All such

circumstances, Kyowa Hakko shall inform Alnylam of such event prior to public disclosure of such
event by Kyowa Hakko. Moreover, subject to the provisions of Section 6.4, Kyowa Hakko shall
prepare and deliver to Alnylam any additional reports required under the Alnylam In-Licenses, in
each case sufficiently in advance to enable Alnylam to comply with its obligations under the
Alnylam In-Licenses. Kyowa Hakko shall also provide such other information to the JCT as Alnylam
may reasonably request and shall keep the JCT reasonably informed of Kyowa Hakko’s
Commercialization activities with respect to the Licensed Product.

     4.7 Sales and Distribution. Each Party and its Related Parties shall be responsible
for booking sales and shall warehouse and distribute the Licensed Product in its own Territory. If
a Party receives any orders for the Product in the other Party’s Territory, it shall refer such
orders to the other Party. Moreover, each Party and its Related Parties shall be solely
responsible for handling all returns of the Product, as well as all aspects of Product order
processing, invoicing and collection, distribution, inventory and receivables, in it own Territory.
With respect to the Licensed Product, Kyowa Hakko may use the services of a Third Party wholesaler
of pharmaceutical products in Japan within its reasonable discretion, and any other Third Party

Kyowa Hakko may distribute in countries in the Kyowa Hakko Territory other than Japan through
Affiliates or Sublicensees of Kyowa Hakko without requiring the consent of Alnylam.

22

 

     4.8 Recalls, Market Withdrawals or Corrective Actions. In the event that any
Regulatory Authority issues or requests a recall or takes a similar action in connection with the
Licensed Product in a Territory, or in the event either Party determines that an event, incident or
circumstance has occurred that may result in the need for a recall or market withdrawal in its own
Territory, the Party notified of such recall or similar action, or the Party that desires such
recall or similar action, shall within [**] hours advise the other Party thereof by telephone or
facsimile. Each Party, in consultation with the other Party, shall decide whether to conduct a
recall in its own Territory and the manner in which any such recall shall be conducted (except in
the case of a government mandated recall, when such Party may act without such advance notice but
shall notify the other Party as soon as possible). Each Party shall bear the expense of any such
recall in its own Territory. Each Party will make available all of its pertinent records that may
be reasonably requested in order to effecting a recall in the other Party’s Territory.

     4.9 Export Monitoring. Each Party and its Related Parties will use Commercially
Reasonable Efforts to monitor and prevent exports of the Licensed Product from its own Territory to
the other Party’s Territory using methods commonly used in the industry for such purpose, and shall
promptly inform the other Party of any such exports of the Licensed Product from its own Territory,
and the actions taken to prevent such exports. Each Party agrees to take any actions reasonably
requested in writing by the other Party that are consistent with applicable law and regulation to
prevent exports of the Licensed Product from its own Territory.

     5. MANUFACTURE AND SUPPLY OF THE LICENSED PRODUCT

     5.1 API Bulk Drug Substance. Alnylam will use Commercially Reasonable Efforts to
Manufacture in accordance with cGMP and supply to Kyowa Hakko API Bulk Drug Substance identical to
the API Bulk Drug Substance Manufactured by Alnylam for use in the Alnylam Territory, in quantities
that are reasonably sufficient for the conduct of Development activities by Kyowa Hakko under the
Development Plan. Kyowa Hakko shall pay Alnylam the Transfer Price for API Bulk Drug Substance
supplied by Alnylam to Kyowa Hakko pursuant to this Section 5.1 within [**] days after receipt of
an invoice therefore. Upon [**] months prior written notice to Alnylam, and subject to any binding
orders for API Bulk Drug Substance made by Kyowa Hakko under the Supply Agreement, Kyowa Hakko may
Manufacture and supply quantities of API Bulk Drug Substance for its own Development activities in
the Kyowa Hakko Territory. Upon receipt of such notice, Alnylam’s obligation to supply API Bulk
Drug Substance to Kyowa Hakko under this Article 5 shall cease (subject to any binding orders for
API Bulk Drug Substance made by Kyowa Hakko under the Supply Agreement). Kyowa Hakko will be
responsible for Manufacturing and supplying API Bulk Drug Substance for Commercial sale in the
Kyowa Hakko Territory.

     5.2 Finished Product. (a) During the Term, Alnylam will use Commercially Reasonable
Efforts to Manufacture in accordance with cGMP and supply to Kyowa Hakko reasonable quantities of
Finished Product, in quantities that are reasonably sufficient for the conduct of Development
activities by Kyowa Hakko under the Development Plan; provided, however, that the
foregoing supply obligation will apply only if the Finished Product for the Kyowa Hakko Territory
is [**] to the Finished Product Manufactured by Alnylam and its Related Parties in the Alnylam
Territory (i.e., [**]). If the Finished Product for the Kyowa Hakko Territory is [**] to the
Finished Product Manufactured by Alnylam and its Related Parties in the Alnylam Territory, then
unless Alnylam agrees in writing to supply such Finished Product, Kyowa Hakko will be responsible
for

23

 

Manufacturing and supplying Finished Product for such purposes in the Kyowa Hakko Territory;
provided, that Alnylam will provide API Bulk Drug Substance in accordance with Section 5.1
hereof. Upon [**] months prior written notice to Alnylam, and subject to any binding orders for
Finished Product made by Kyowa Hakko under the Supply Agreement, Kyowa Hakko may Manufacture and
supply quantities of Finished Product for its own Development activities in the Kyowa Hakko
Territory. Moreover, Kyowa Hakko will be responsible for Manufacturing and supplying Finished
Product for Commercial sale in the Kyowa Hakko Territory and for the final labeling and packaging
of all Finished Product used for Development or Commercialization in the Kyowa Hakko Territory.

     (b) Alnylam will supply Finished Product to Kyowa Hakko at the Transfer Price for such
Finished Product. To the extent not included in Cost of Goods Sold, Kyowa Hakko will reimburse
Alnylam for its internal and out-of-pocket expenses additionally incurred in connection with the
Manufacture of API Bulk Drug Substance and/or Finished Product specifically for the Kyowa Hakko
Territory, including without limitation, process development, process validation, process
improvement, formulation development, product characterization, manufacturing scale-up and recovery
costs, the development of SOPs and QA/QC methods and procedures, the production of qualification
lots, all additional costs incurred in obtaining and maintaining approval for the Manufacture of
such API Bulk Drug Substance and/or Finished Product specifically for the Kyowa Hakko Territory,
and the costs of preparing, submitting, reviewing and developing data and information for the
purpose of a drug master file or for submission to a Regulatory Authority to obtain or retain such
approvals in the Kyowa Hakko Territory.

     5.3 Supply Agreement; Manufacturing Technology Transfer. (a) Within [**] months after
the Effective Date, the Parties will negotiate in good faith and enter into a supply agreement
pursuant to which Alnylam will, subject to the terms of Section 5.2, initially supply API Bulk Drug
Substance and/or Finished Product to Kyowa Hakko (the “Supply Agreement”). The Supply Agreement
will include the terms set forth in Schedule 5.3.

     (b) Until First Commercial Sale of the Licensed Product in the Kyowa Hakko Territory, upon
receipt of Kyowa Hakko’s written notice described in Sections 5.1 or 5.2(a), Alnylam shall provide
Kyowa Hakko promptly with Alnylam Know-How for the Manufacture of the API Bulk Drug Substance
and/or Finished Product, as the case may be, and shall make available its personnel on a reasonable
basis to consult with Kyowa Hakko with respect thereto, all at Kyowa Hakko’s expense (calculated on
a reasonable full-time equivalent personnel and out-of-pocket expenses basis). In such a case, the
Parties will negotiate in good faith and enter into a technical transfer agreement setting forth
the scope of the technical Know-How transfer and the expense reimbursement agreed between the
Parties.

Dollars ($15,000,000).

     7.2 Development Milestone Fees. (a) Kyowa Hakko shall make the non-refundable,
non-creditable milestone payments to Alnylam set forth below no later than [**] days after the
earliest date on which the corresponding milestone event has first been achieved with respect to

event the criteria set forth in Section 7.2(b) are satisfied, in which case milestone fees shall be
paid in accordance with Section 7.2(b).

     (c) Each milestone payment by Kyowa Hakko to Alnylam hereunder shall be payable only once,
regardless of the number of times achieved with respect to the Licensed Product. For clarity,
Kyowa Hakko shall not be obligated to make any payments with respect to milestones achieved by the
Replacement Product for which Kyowa Hakko has already made a milestone payment with respect to the
Lead Product. If any of the foregoing milestones are not achieved, but a subsequent milestone is
achieved, then the milestone payment for the milestone(s) not achieved shall be due and payable to
Alnylam concurrently with the milestone payment for the milestone that has been achieved. For
example, under the milestone schedule set forth in Section 7.2(a), if Kyowa Hakko [**], then Kyowa
Hakko will owe Alnylam an aggregate milestone payment of $[**].

28

 

     7.3 Sales Milestone Fees. Kyowa Hakko shall make the non-refundable, non-creditable
milestone payments to Alnylam set forth below no later than [**] days after the earliest date on
which the corresponding milestone event has first been achieved with respect to the Licensed
Product.

With respect to the foregoing Sales Milestones, payment shall be made only once for each milestone
regardless of the number of times cumulative Net Sales for the Licensed Product in the Kyowa Hakko
Territory reach a particular dollar threshold. If Kyowa Hakko achieves a higher Net Sales
milestone in a Calendar Year without having first achieved a lower Net Sales milestone in any
previous Calendar Year, then the milestone payment(s) for the lower Net Sales milestone(s) shall be
due and payable to Alnylam concurrently with the milestone payment for the higher Net Sales
milestone that has been achieved. For example, if aggregate Net Sales of the Licensed Product in
the Kyowa Hakko Territory are $[**] in the first Calendar Year, and then $[**] in the next Calendar
Year, then Kyowa Hakko will owe Alnylam a milestone payment of $[**] with respect to the second
calendar year [**].

     7.4 Royalties.

     7.4.1 Royalties Payable on the Licensed Product. Subject to the terms and conditions
of this Agreement, Kyowa Hakko shall pay to Alnylam royalties on aggregate Net Sales by Kyowa Hakko
and its Related Parties of the Licensed Product, as follows:

	 	 	 
	 	 	Royalty
	Aggregate Calendar Year	 	(as a percentage of Net
	Net Sales in the Kyowa Hakko Territory	 	Sales)
	$[**]

	 	[**]%
	$[**]

	 	[**]%
	$[**]

	 	[**]%
	Greater than $[**]

	 	[**]%

     Royalties on aggregate Net Sales shall be paid at the rate applicable to the portion of such
aggregate Net Sales within each of the Net Sales levels above during such Calendar Year.

     7.4.2 Royalty Term. Royalties on Net Sales of the Licensed Product at the rates set
forth in Section 7.4.1 shall continue to be payable on a country-by-country basis, until the later
of (a) the expiration of the last Valid Claim of the Alnylam Patent Rights Covering the Manufacture
of the Licensed Product in the country of Manufacture or sale, or the Commercialization of the
Licensed Product in the country of sale, and (b) the tenth (10th) anniversary of the
First Commercial Sale in the

29

 

country of sale (each such period, a “Royalty Term”). Only one royalty shall be due with respect to
the same unit of Licensed Product, and no royalties shall be due upon the sale or other transfer
among Kyowa Hakko or its Related Parties, but in such cases the royalty shall be due and calculated
upon Kyowa Hakko’s or its Related Party’s Net Sales to the first independent Third Party.

     7.4.3 Necessary Third Party IP. Alnylam shall bear (a) one hundred percent (100%) of
any royalties, any upfront fees, milestones or other payments under the Existing Alnylam
In-Licenses, and (b) [**] percent ([**]%) of any royalties, any upfront fees, milestones or other
payments under any Alnylam In-Licenses other than the Existing Alnylam In-Licenses, that are
reasonably allocable to Necessary Third Party IP used by Kyowa Hakko in the Development,
Manufacture or Commercialization of the Licensed Product in the Field in the Kyowa Hakko Territory.
Subject to Kyowa Hakko’s right to offset payments of royalties, upfront fees and milestone payments
pursuant to Section 7.4.4(a), Kyowa Hakko shall bear (i) one hundred percent (100%) of any
royalties, upfront fees, milestones or other payments under the Kyowa Hakko In-Licenses, and (ii)
[**] percent ([**]%) of any royalties, upfront fees, milestones or other payments under any Alnylam
In-Licenses other than the Existing Alnylam In-Licenses, that are reasonably allocable to Necessary
Third Party IP used by Kyowa Hakko in the Development, Manufacture or Commercialization of the
Licensed Product in the Field in the Kyowa Hakko Territory.

     7.4.4 Royalty Adjustments.

     (a) Necessary Third Party IP. Subject to Section 7.4.4(e), the aggregate royalties
payable to Alnylam pursuant to Section 7.4.1 in any period will be reduced by [**] percent ([**]%)
of the amount paid by Kyowa Hakko in royalties and upfront fees and milestone payments in such
period under all Kyowa Hakko In-Licenses of Necessary Third Party IP that are reasonably allocable
to the Development, Manufacture or Commercialization of the Licensed Product in the Field in the
Kyowa Hakko Territory.

     (b) No Alnylam Patent Rights. Subject to Section 7.4.4(e), in the event that there is
no Valid Claim of an Alnylam Patent Right in a country of the Kyowa Hakko Territory on the date of
the First Commercial Sale of the Licensed Product in such country, then in each Calendar Quarter in
which there is no Valid Claim of an Alnylam Patent Right in such country, the royalties payable to
Alnylam in respect of the Licensed Product in such country shall be reduced to [**] percent ([**]%)
of the royalties that would otherwise be payable to Alnylam in such Calendar Quarter with respect
to the Licensed Product in such country pursuant to Section 7.4.1. For clarity, the royalty
adjustment in this Section 7.4.4(b) shall not apply to any country of the Kyowa Hakko Territory in
which there is a Valid Claim of an Alnylam Patent Right on the date of the First Commercial Sale of
the Licensed Product in such country.

     (c) Generic Products. Subject to Section 7.4.4(e), in the event that there is a Valid
Claim of an Alnylam Patent Right in a country of the Kyowa Hakko Territory on the date of the First
Commercial Sale of the Licensed Product in such country, and if, in any Calendar Quarter after [**]
Generic Products (defined below) is launched in such country of the Kyowa Hakko Territory the
market share of all Generic Product(s) in such country is equal to or greater than [**] percent
([**]%) of the amount of aggregate sales of the Licensed Product and all Generic Product(s) in such
country, then the royalties payable by Kyowa Hakko to Alnylam in respect of the Licensed Product in
such country shall be reduced in such Calendar Quarter to [**] percent ([**]%) of the royalties
that would otherwise be payable to Alnylam in such Calendar Quarter with respect to the Licensed
Product in

30

 

such country pursuant to Section 7.4.1. For clarity, the royalty adjustment in this Section
7.4.4(c) shall not apply to any country of the Kyowa Hakko Territory in which there is no Valid
Claim of an Alnylam Patent Right on the date of the First Commercial Sale of the Licensed Product
in such country. “Generic Product” means any pharmaceutical product that contains an active
pharmaceutical ingredient with the exact generic name of the active pharmaceutical ingredient in
the Licensed Product.

     (d) Certain Infringement Claims. Subject to Section 7.4.4(e), the aggregate royalties
payable to Alnylam pursuant to Section 7.4.1 in any period will be reduced by [**] percent ([**]%)
of the amount of Losses paid by Kyowa Hakko to Third Parties arising directly out of Third Party
Infringement Claims based solely on the use of Alnylam Know-How or Alnylam Patent Rights in the
Development or Commercialization of the Licensed Product in, or Manufacture of Licensed Product
for, the Kyowa Hakko Territory and in the Field.

     (e) Cumulative Adjustments. Notwithstanding anything to the contrary herein, under no
circumstances will aggregate royalties due to Alnylam with respect to the Licensed Product in any
country of the Kyowa Hakko Territory in any period be reduced to an amount less than the greater of
(i) [**] percent ([**]%) of the royalties otherwise payable by Kyowa Hakko to Alnylam under Section
7.4.1 in such period with respect to such country and (ii) the aggregate amount of any royalties
payable under the Alnylam In-Licenses that are reasonably allocable to the Commercialization or
Manufacture of the Licensed Product in such country in such period (where such royalties are
calculated by adding [**] to the sum of the applicable royalty rate(s) in the applicable Alnylam
In-Licenses).

     7.4.5 Blended Royalty Rates. The Parties acknowledge and agree that the Patent Rights
and Know-How licensed pursuant to this Agreement justify royalty rates of differing amounts with
respect to the sales of the Licensed Product, which rates could be applied separately to the
Licensed Product involving the exercise of such Patent Rights and/or the incorporation of such
Know-How, and that, if such royalties were calculated separately, royalties relating to Patent
Rights and royalties relating to Know-How would last for different terms. Notwithstanding the
foregoing, the Parties have determined, for reasons of convenience, that blended royalty rates for
the Patent Rights and the Know-How licensed hereunder, as set forth above, will apply during a
single royalty term.

     7.4.6 Reports; Payment of Royalty. During the Term, commencing upon the First
Commercial Sale of the Licensed Product in the Kyowa Hakko Territory, Kyowa Hakko shall furnish to
Alnylam (a) a written report within [**] days of after the end of each Calendar Quarter showing the
estimated quantity of the Licensed Product sold in each country (as measured in grams of active
pharmaceutical ingredient or saleable units of product, as the Parties may agree) and the Net Sales
of the Licensed Product in each country (and any other detail reasonably available through Kyowa
Hakko’s internal sales reporting system) for the previous month, in each case on an unaudited
basis; and (b) a quarterly written report showing the quantity of the Licensed Product sold in each
country (as measured in grams of active pharmaceutical ingredient or saleable units of product, as
the Parties may agree), the gross sales of the Licensed Product in each country, and as applicable,
itemized deductions for the Licensed Product for each country included in the calculation of Net
Sales, the Net Sales in each country of the Licensed Product during the reporting period,
royalties, upfront fees, milestones or other payments payable to Third Parties under all Kyowa
Hakko In-Licenses of Necessary Third Party IP that are reasonably allocable to the Development,
Manufacture or Commercialization of the Licensed Product in the Field in the Kyowa Hakko Territory,
the launch of any Generic Product in each country of the Kyowa Hakko Territory, the market share of
all Generic Products in each country

31

 

of the Kyowa Hakko Territory as a percentage of the aggregate market share of the Licensed
Product and all Generic Products in such country, and the royalties payable under this Agreement.
Quarterly reports shall be due no later than the [**] day following the end of each Calendar
Quarter. In addition, subject to the provisions of Section 6.4, Kyowa Hakko shall prepare and
deliver to Alnylam any additional reports as required under the Alnylam In-Licenses. Royalties
shown to have accrued by each royalty report shall be due and payable on the date such royalty
report is due. Kyowa Hakko and its Related Parties shall keep complete and accurate records in
sufficient detail to enable the royalties and other payments payable hereunder and by Alnylam to
Third Parties under the Alnylam In-Licenses to be determined.

     7.5 Audits.

     7.5.1 Upon the written request of a Party and not more than [**] in each Calendar Year, the
other Party and its Related Parties shall permit an independent certified public accounting firm of
internationally-recognized standing selected by the requesting Party and reasonably acceptable to
the other Party, at the requesting Party’s expense except as set forth below, to have access during
normal business hours to such of the records of the other Party as may be reasonably necessary to
verify the accuracy of the royalty and other reports hereunder for any year ending not more than
[**] years prior to the date of such request for the sole purpose of verifying the basis and
accuracy of payments made under Sections 2.6, 10.3.6, 10.9 and Articles 5 and 7.

     7.5.2 If such accounting firm identifies a discrepancy made during such period, the
appropriate Party shall pay the other Party the amount of the discrepancy, together with
late-payment interest calculated at the rate of [**] percent ([**]%) per month, within [**]
business days of the date the requesting Party delivers to the other Party such accounting firm’s
written report so concluding, or as otherwise agreed by the Parties in writing. Such written
report shall be binding upon the Parties. The fees charged by such accounting firm shall be paid
by the requesting Party, unless such discrepancy represents an underpayment by the other Party of
at least the lesser of [**] U.S. dollars ($[**]) or [**] percent ([**]%) of the total amounts due
hereunder in a Calendar Year, in which case such fees shall be paid by the other Party.

     7.5.3 Subject to the provisions of Section 6.4, Kyowa Hakko shall comply with all applicable
audit requirements in the Alnylam In-Licenses and shall include in each sublicense granted by it
pursuant to this Agreement a provision requiring the Sublicensee to make reports to Alnylam, to
keep and maintain records of sales made pursuant to such sublicense and to grant access to such
records by Alnylam’s independent accountant to the same extent required of Kyowa Hakko under this
Agreement.

     7.5.4 Unless an audit for such year has been commenced upon the expiration of [**] years
following the end of any year, the calculation of royalties, expense reimbursement and other
payments payable with respect to such year shall be binding and conclusive upon both Parties, and
each Party and its Related Parties shall be released from any further liability or accountability
with respect to such royalties or expense reimbursement for such year.

     7.5.5 Each Party shall treat all financial information subject to review under this Section
7.5 or under any sublicense agreement in accordance with the confidentiality and non-use provisions
of this Agreement, and shall cause its accounting firm to enter into an acceptable confidentiality

32

 

agreement with the other Party and/or its Related Parties obligating it to retain all such
information in confidence pursuant to such confidentiality agreement.

     7.6 Payment Exchange Rate. All payments to be made under this Agreement shall be made
in United States dollars and shall be paid by bank wire transfer in immediately available funds to
such bank account in the United States as may be designated in writing by the receiving Party from
time to time. In the case of Net Sales made or expenses incurred by Kyowa Hakko and its Related
Parties, the rate of exchange to be used in computing the amount of currency equivalent in United
States dollars due shall be made at the rate of exchange utilized by such party in its worldwide
accounting system and calculated in accordance with generally accepted accounting principles in the
United States consistently applied, prevailing on the last day of each Calendar Quarter for royalty
payments, and the third to the last business day of the month preceding the month in which such
sales or expenses are recorded for other payments, as the case may be.

     7.7 Income Tax Withholding. Each Party shall use reasonable efforts to minimize tax
withholding on payments made to the other Party. Notwithstanding such efforts, if such Party
concludes that tax withholdings under the applicable laws of any country are required with respect
to payments to the other Party, such Party shall first notify the other Party and provide such
Party with [**] business days to determine whether there are actions such receiving Party can
undertake to avoid such withholding. The paying Party shall refrain from making such payment until
the receiving Party instructs the paying Party that (a) the paying Party intends to take actions
that will obviate the need for such withholding, in which case the paying Party shall make such
payment only after it is instructed to do so by the receiving Party, or (b) the paying Party should
make such payment and withhold the required amount and pay it to the appropriate governmental
authority. In such case, the withholding Party shall promptly provide the other Party with copies
of receipts or other evidence reasonably required and sufficient to allow the other Party to
document such tax withholdings adequately for purposes of claiming foreign tax credits and similar
benefits. The Parties will cooperate reasonably in completing and filing documents required under
the provisions of any applicable tax laws or under any other applicable law, in connection with the
making of any required tax payment or withholding payment, or in connection with any claim to a
refund of or credit for any such payment. The Parties will cooperate to minimize such taxes in
accordance with applicable laws. Notwithstanding the foregoing, Alnylam represents that zero
percent (0%) withholding shall be required in respect of the payments to be paid by Kyowa Hakko to
Alnylam pursuant to Section 7.1, 7.2 and 7.3 hereof, because of the eligibility of Alnylam as a
publicly traded U.S. tax resident for purposes of the U.S.-Japan Income Tax Treaty. Alnylam shall
be solely responsible for its costs incurred in registering under such treaty.

8. CONFIDENTIALITY AND PUBLICATION

     8.1 Nondisclosure Obligation. (a) All Confidential Information disclosed by one Party
to the other Party hereunder shall be maintained in confidence by the receiving Party and shall not
be disclosed to a Third Party or used for any purpose except as set forth herein without the prior
written consent of the disclosing Party, except to the extent that such Confidential Information:

	 	(i)	 	is known by the receiving Party at the time of its receipt, and not through a
prior disclosure by the disclosing Party, as documented by the receiving Party’s
business records;

33

 

	 	(ii)	 	is in the public domain by use and/or publication before its receipt from the
disclosing Party, or thereafter enters the public domain through no fault of the
receiving Party;
	 
	 	(iii)	 	is subsequently disclosed to the receiving Party by a Third Party who may
lawfully do so and is not under an obligation of confidentiality to the disclosing
Party; or
	 
	 	(iv)	 	is developed by the receiving Party independently of Confidential Information
received from the disclosing Party, as documented by the receiving Party’s business
records.

     (b) Notwithstanding the obligations of confidentiality and non-use set forth above and in
Section 8.2 below, a receiving Party may provide Confidential Information disclosed to it, and
disclose the existence and terms of this Agreement as may be reasonably required in order to
perform its obligations and to exploit its rights under this Agreement, and specifically to (i)
Related Parties, and their employees, directors, agents, consultants, advisors and/or other Third
Parties for the performance of its obligations hereunder (or for such entities to determine their
interest in performing such activities) in accordance with this Agreement in each case who are
obligated to keep such Confidential Information confidential; (ii) governmental or other Regulatory
Authorities in order to obtain patents or perform its obligations or exploit its rights under this
Agreement; provided, that such Confidential Information shall be disclosed only to the
extent reasonably necessary to do so, (iii) the extent required by applicable law, including
without limitation by the rules or regulations of the United States Securities and Exchange
Commission or similar regulatory agency in a country other than the United States or of any stock
exchange or listing entity, (iv) any bona fide actual or prospective underwriters, investors,
lenders or other financing sources and any bona fide actual or prospective collaborators or
strategic partners and to consultants and advisors of such Party, in each case who are obligated to
keep such Confidential Information confidential, and (v) to Third Parties to the extent a Party is
required to do so pursuant to the terms of an In-License.

If a Party is required by judicial or administrative process to disclose Confidential Information
that is subject to the non-disclosure provisions of this Section 8.1 or Section 8.2, such Party
shall promptly inform the other Party of the disclosure that is being sought in order to provide
the other Party an opportunity to challenge or limit the disclosure obligations. Confidential
Information that is disclosed by judicial or administrative process shall remain otherwise subject
to the confidentiality and non-use provisions of this Section 8.1 and Section 8.2, and the Party
disclosing Confidential Information pursuant to law or court order shall take all steps reasonably
practical, including without limitation seeking an order of confidentiality, to ensure the
continued confidential treatment of such Confidential Information. In addition to the foregoing
restrictions on public disclosure, if either Party concludes that a copy of this Agreement must be
filed with the United States Securities and Exchange Commission or similar regulatory agency in a
country other than the United States, such Party shall provide the other Party with a copy of this
Agreement showing any sections as to which the Party proposes to request confidential treatment,
will provide the other Party with an opportunity to comment on any such proposal and to suggest
additional portions of the Agreement for confidential treatment, and will take such Party’s
reasonable comments into consideration before filing the Agreement.

     8.2 Publication and Publicity.

     8.2.1 Publication. Kyowa Hakko and Alnylam each acknowledge the other Party’s interest in
publishing the results of the Collaboration. Each Party also recognizes the mutual interest in
obtaining valid patent protection and in protecting business interests and trade secret
information. Consequently, except for disclosures permitted pursuant to Section 8.1 and 8.2.2(b),
either Party, its

34

 

Affiliates, or their respective employees or consultants wishing to make a publication or a
disclosure to a Third Party relating to the Collaboration or the Licensed Product that contains the
Confidential Information of the other Party shall deliver to the other Party a copy of the proposed
written publication or an outline of an oral disclosure at least [**] days prior to submission for
publication or presentation. The reviewing Party shall have the right (a) to propose modifications
to the publication or presentation for patent reasons, trade secret reasons or business reasons, or
(b) to request a reasonable delay in publication or presentation in order to protect patentable
information. If the reviewing Party requests a delay, the publishing Party shall delay submission
or presentation for a period of [**] days to enable patent applications protecting each Party’s
rights in such information to be filed in accordance with Article 10 below. Upon expiration of
such [**] day period, the publishing Party shall be free to proceed with the publication or
presentation. If the reviewing Party requests modifications to the publication or presentation,
the publishing Party shall edit such publication to prevent disclosure of trade secret, patentable
or proprietary business information prior to submission of the publication or presentation. With
respect to any proposed publications or disclosures by investigators or academic or non-profit
collaborators, such materials shall be subject to review under this Section 8.2 to the extent that
Kyowa Hakko or Alnylam, as the case may be, has the right and ability (after using Commercially
Reasonable Efforts to obtain such right and ability) to do so.

     8.2.2 Publicity. (a) Except as set forth in Section 8.1 above and clause (b) below, the terms
of this Agreement may not be disclosed by either Party, and no Party shall use the name, trademark,
trade name or logo of the other Party or its employees in any publicity, news release or disclosure
relating to this Agreement or its subject matter, without the prior express written permission of
the other Party, except as may be required by law or expressly permitted by the terms hereof.

     (b) The initial press release to be issued jointly by the Parties publicizing the execution of
this Agreement shall be as set forth in Schedule 8.2.2. After such initial press release,
neither Party shall issue a press release or public announcement relating to this Agreement without
the prior written approval of the other Party, which approval shall not be unreasonably withheld or
delayed, except that a Party may (i) once a press release or other written statement is approved in
writing by both Parties, make subsequent public disclosure of the information contained in such
press release or other written statement without the further approval of the other Party, and (ii)
issue a press release or public announcement as required, in the reasonable judgment of such Party,
by applicable law, including without limitation by the rules or regulations of the United States
Securities and Exchange Commission or similar regulatory agency in a country other than the United
States or of any stock exchange or listing entity.

     9. REPRESENTATIONS, WARRANTIES AND COVENANTS; INDEMNIFICATION

     9.1 Mutual Representations and Warranties. Each Party represents and warrants to the
other Party that as of the Effective Date of this Agreement:

first eligible
to seek patent term restoration or extension of any such Patent Rights or any SPC related
thereto shall have the right to do so; provided, that if in any country the first Party has
an option to extend the patent term for only one of several patents, the first Party shall consult

a license under this Section 10.9 of this Agreement) for the Licensed Product in its Territory at
its sole discretion, and each Party and its Affiliates shall retain all right, title and interest
in and to its and their respective corporate names and logos.

          (b) Kyowa Hakko will develop and propose, and the JCT shall review and comment on, one or more
Product Trademark(s) for use by Kyowa Hakko and its Related Parties throughout the Kyowa Hakko
Territory. Such Product Trademark(s) considered by the JCT may include the Product Trademark(s)
developed and/or used by Alnylam with respect to the Commercialization of the Licensed Product in
the Alnylam Territory (the “Alnylam Trademarks”). Any Product Trademark(s) (other than the Alnylam
Trademarks) that are used by Kyowa Hakko to promote and sell the Licensed Product in the Kyowa
Hakko Territory are hereinafter referred to as the “Kyowa Hakko Trademarks”. Alnylam (or its
Related Parties, as appropriate) shall own all rights to Alnylam Trademarks, and all goodwill
associated therewith, throughout the Alnylam Territory and the Kyowa Hakko Territory. Kyowa Hakko
(or its Related Parties, as appropriate) shall own all rights to Kyowa Hakko Trademarks and all

Territory, then the following provisions shall apply: Alnylam shall grant Kyowa Hakko an exclusive
license to use such Alnylam Trademarks to Commercialize the Product in the Kyowa Hakko Territory.
Kyowa Hakko agrees that the quality of the Licensed Product and the Manufacture and
Commercialization thereof shall be consistent with the quality standards applied by Alnylam
thereto. In addition, Kyowa Hakko shall comply strictly with Alnylam’s trademark style and
usage standards that Alnylam communicates to Kyowa Hakko from time to time with respect to the
Alnylam Trademarks. Kyowa Hakko shall at its own expense, at the request of Alnylam from time to
time, submit to Alnylam for approval a reasonable number of production samples of the Licensed
Product and related packaging materials. In the event that Alnylam reasonably objects to the
quality of the Licensed Product or the usage of the Alnylam Trademarks Controlled by it in
connection with any sample, it shall give written notice of such objection to Kyowa Hakko within
[**] days of receipt by Alnylam of the sample, specifying the way in which such usage of its
Alnylam Trademarks fails to meet the style, usage or quality standards for the Licensed Product set
forth in the first two sentences

44

 

of this Section 10.9(c), and Kyowa Hakko shall immediately cease
sale and distribution of the Licensed Product. If Kyowa Hakko wishes to continue to distribute and
sell the Licensed Product, it must remedy the failure and submit further samples to Alnylam for
approval.

          (d) If Alnylam Trademarks are used to promote and sell the Licensed Product in the Kyowa Hakko
Territory, then Alnylam will use Commercially Reasonable Efforts to establish, maintain and enforce
such Alnylam Trademarks in the applicable countries of the Kyowa Hakko Territory during the Term.
Kyowa Hakko shall be responsible for one hundred percent (100%) of the costs of such efforts in the
Kyowa Hakko Territory and Kyowa Hakko shall reimburse Alnylam for all such costs incurred by
Alnylam within [**] days after receiving any invoice from Alnylam for such costs. Kyowa Hakko will
use Commercially Reasonable Efforts to establish, maintain and enforce the Kyowa Hakko Trademarks
in the Kyowa Hakko Territory during the Term, at its expense.

          (e) In the event either Party becomes aware of any infringement of any Product Trademark by a
Third Party, such Party shall promptly notify the other Party and the Parties shall consult with
each other and jointly determine the best way to prevent such infringement, including, without
limitation, by the institution of legal proceedings against such Third Party.

     11. TERM AND TERMINATION

     11.1 Term. This Agreement shall be effective as of the Effective Date and, unless
terminated earlier pursuant to Section 11.2 below, this Agreement shall continue in effect on a
country by country basis until expiration of the last Royalty Term to expire under this Agreement
(“Term”). Upon expiration of the Term, all licenses of the Parties under Article 6 then in effect
shall become fully paid-up, perpetual, non-exclusive licenses.

     11.2 Termination Rights.

     11.2.1 Termination for Convenience. Kyowa Hakko shall have the right to terminate
this Agreement at any time after the Effective Date on six (6) months prior written notice to
Alnylam.

     11.2.2 Termination for Cause. This Agreement may be terminated at any time during the
Term:

     (a) upon written notice by either Party if the other Party is in breach of its material
obligations hereunder by causes and reasons within its control and has not cured such breach within
[**] business days in the case of a payment breach, or [**] days in the case of all other
breaches, after notice requesting cure of the breach; or

     (b) by either Party upon the filing or institution of bankruptcy, reorganization, liquidation
or receivership proceedings, or upon an assignment of a substantial portion of the assets for the
benefit of creditors by the other Party; provided, however, that in the event of
any involuntary bankruptcy or receivership proceeding such right to terminate shall only become
effective if the Party consents to the involuntary bankruptcy or receivership or such proceeding is
not dismissed within sixty (60) days after the filing thereof.

45

 

     11.2.3 Challenges of Patent Rights. In the event that Kyowa Hakko or any of its
Related Parties (a) commences or participates in any action or proceeding (including, without
limitation, any patent opposition or re-examination proceeding), or otherwise asserts any claim,
challenging or denying the validity or enforceability of any of the Patent Rights licensed Kyowa
Hakko under this Agreement, or any claim thereof or (b) actively assists any other person or entity
in bringing or prosecuting any action or proceeding (including, without limitation, any patent
opposition or re-examination proceeding) challenging or denying the validity or enforceability of
any of such Patent Rights or any claim thereof, then (i) Kyowa Hakko shall give notice thereof to
Alnylam within [**] days of taking such action and (ii) Alnylam will have the right, in its sole
discretion to give notice to Kyowa Hakko that the licenses and option rights granted to Kyowa Hakko
with respect to all or any portion of the Patent Rights under this Agreement will terminate in [**]
days following such notice (or such longer period as Alnylam may designate in such notice), and,
unless Kyowa Hakko withdraws or causes to be withdrawn all such challenge(s) within such [**]-day
period, such licenses and option rights will so terminate. In the event that Alnylam is not
permitted under applicable law to terminate the licenses and option rights with respect to all the
Patent Rights under this Agreement, then the Parties agree to construe this provision as to permit
Alnylam to terminate the licenses and option rights to that portion of such Patent Rights with
respect to which Alnylam has the legal right to do so.

     11.2.4 Effect of Termination.

     (a) Termination by Alnylam. Without limiting any other legal or equitable remedies
that Alnylam may have, if Alnylam terminates this Agreement in accordance with Sections 11.2.2(a)
or (b), then (i) Kyowa Hakko’s obligations under Section 9.4.1 shall survive for a period of [**]
after the effective date of termination, (ii) the license grant to Alnylam in Section 6.1.4 shall
survive, (iii) Kyowa Hakko shall as promptly as practicable transfer to Alnylam or Alnylam’s
designee (A) possession and ownership of all governmental or regulatory correspondence,
conversation logs, filings and approvals (including all Regulatory Approvals and pricing and
reimbursement approvals) relating to the Development, Manufacture or Commercialization of the
Licensed Product and all Kyowa Hakko Trademarks, (B) copies of all data, reports, records and
materials, and other sales and marketing related information in Kyowa Hakko’s possession or Control
to the extent that such data, reports, records, materials or other information relate to the
Development, Manufacture or Commercialization of the Licensed Product, including without limitation
all non-clinical and clinical data relating to the Licensed Product, and customer lists and
customer contact information and all adverse event data in Kyowa Hakko’s possession or Control;
provided, that (i) Kyowa Hakko shall not be required by this provision to provide any
confidential information to Alnylam and (ii) Kyowa Hakko shall use Commercially Reasonable Efforts
to obtain for Alnylam the right to access all such data, reports, records, materials, and other
sales and marketing related information, and (C) all records and materials
in Kyowa Hakko’s possession or Control containing Confidential Information of Alnylam, (iv)
appoint Alnylam as Kyowa Hakko’s and/or Kyowa Hakko’s Related Parties’ agent for all Licensed
Product-related matters involving Regulatory Authorities in the Kyowa Hakko Territory until all
Regulatory Approvals and other regulatory filings have been transferred to Alnylam or its designee,
(v) if the effective date of termination is after First Commercial Sale, then Kyowa Hakko shall
appoint Alnylam as its exclusive distributor of the Licensed Product in the Kyowa Hakko Territory
and grant Alnylam the right to appoint sub-distributors, until such time as all Regulatory
Approvals in the Kyowa Hakko Territory have been transferred to Alnylam or its designee, (vi) if
Kyowa Hakko or its Related Parties are Manufacturing Finished Product, at Alnylam’s option, supply
the Finished Product to Alnylam in the Kyowa Hakko Territory on terms no less favorable than those
on which Kyowa Hakko supplied the

46

 

Finished Product prior to such termination to its most favored
distributor in the Kyowa Hakko Territory, until such time as all Regulatory Approvals in the Kyowa
Hakko Territory have been transferred to Alnylam or its designee, Alnylam has obtained all
necessary manufacturing approvals and Alnylam has procured or developed its own source of Finished
Product supply, (vii) if Alnylam so requests, Kyowa Hakko shall transfer to Alnylam any Third Party
agreements relating to the Development, Manufacture or Commercialization of the Licensed Product to
which Kyowa Hakko is a party, subject to any required consents of such Third Party, which Kyowa
Hakko shall use Commercially Reasonable Efforts to obtain promptly, and (viii) Kyowa Hakko shall
grant Alnylam an exclusive right and license, with the right to grant sublicenses, under all Kyowa
Hakko Technology to Develop, Manufacture and Commercialize the Licensed Product in the Field. The
license granted pursuant to this Section 11.2.4(a) shall be royalty-free, fully-paid and perpetual.
Kyowa Hakko shall execute all documents and take all such further actions as may be reasonably
requested by Alnylam in order to give effect to the foregoing clauses (i) through (viii).

     (b) Termination by Kyowa Hakko for Convenience. Without limiting any other legal or
equitable remedies that Alnylam may have, if Kyowa Hakko terminates this Agreement in accordance
with Section 11.2.1, then (i) Kyowa Hakko’s obligations under Section 9.4.1 shall survive for a
period of [**] after the effective date of termination, (ii) the provisions of Section
11.2.4(a)(ii)-(vii) shall apply, and (iii) Kyowa Hakko shall grant to Alnylam a non-exclusive right
and license, with the right to grant sublicenses, under all Kyowa Hakko Technology that relates
solely to the Licensed Product, to Develop, Manufacture and Commercialize the Licensed Product in
the Field. The licenses granted pursuant to this Section 11.2.4(b) shall be royalty-free,
fully-paid and perpetual. Kyowa Hakko shall execute all documents and take all such further
actions as may be reasonably requested by Alnylam in order to give effect to the foregoing clauses
(i) through (iii).

     (c) Termination by Kyowa Hakko. Without limiting any other legal or equitable remedies
that Kyowa Hakko may have, if Kyowa Hakko terminates this Agreement in accordance with Section
11.2.2(a) or (b), then the licenses granted to Alnylam under this Agreement shall terminate and the
licenses and option rights granted to Kyowa Hakko under this Agreement shall continue in full force
and effect; provided, that Kyowa Hakko continues to use Commercially Reasonable Efforts to
Develop and Commercialize the Licensed Product, pay all amounts due to Alnylam pursuant to Article
7 that would otherwise be applied to Commercialization of the Licensed Product and comply in all
respects with the requirements of each Alnylam In-License; and provided, further,
that if Kyowa Hakko terminates this Agreement pursuant to Section 11.2.2(a), the royalty dollar
amounts payable to Alnylam pursuant to Section 7.4 shall be reduced by up to [**]%, such amount to
be determined by arbitrators pursuant to Section 12.11.2 if such arbitrators determine that such
remedy is appropriate
(and for purposes of clarity, this reduction shall not apply to the royalty rate but to the
royalty payment determined pursuant to Article 7 hereof) and Kyowa Hakko shall be entitled to
deduct from any royalties payable to Alnylam under Article 7 the amount of any monetary payments
awarded to Kyowa Hakko pursuant to a final decision of the arbitrators pursuant to Section 12.11.2.

     (d) Termination upon Bankruptcy of a Party. If this Agreement is terminated by either
Party (the “Non-Bankrupt Party”) pursuant to Section 11.2.2(b) due to the rejection of this
Agreement by or on behalf of the other Party (the “Bankrupt Party”) under Section 365 of the United
States Bankruptcy Code (the “Code”), all licenses and rights to licenses granted under or pursuant
to this Agreement by the Bankrupt Party to the Non-Bankrupt Party are, and shall otherwise be
deemed to

47

 

be, for purposes of Section 365(n) of the Code, licenses of rights to “intellectual
property” as defined under Section 101(35A) of the Code. The Parties agree that the Non-Bankrupt
Party, as a licensee of such rights under this Agreement, shall retain and may fully exercise all
of its rights and elections under the Code, and that upon commencement of a bankruptcy proceeding
by or against the Bankrupt Party under the Code, the Non-Bankrupt Party shall be entitled to a
complete duplicate of, or complete access to (as the Non-Bankrupt Party deems appropriate), any
such intellectual property and all embodiments of such intellectual property. Such intellectual
property and all embodiments thereof shall be promptly delivered to the Non-Bankrupt Party (i) upon
any such commencement of a bankruptcy proceeding upon written request therefor by the Non-Bankrupt
Party, unless the Bankrupt Party elects to continue to perform all of its obligations under this
Agreement or (ii) if not delivered under (i) above, upon the rejection of this Agreement by or on
behalf of the Bankrupt Party upon written request therefor by the Non-Bankrupt Party. The
foregoing provisions are without prejudice to any rights the Non-Bankrupt Party may have arising
under the Code or other applicable law.

     11.3 Effect of Expiration or Termination; Survival. Expiration or termination of this
Agreement shall not relieve the Parties of any obligation accruing prior to such expiration or
termination. Any expiration or termination of this Agreement shall be without prejudice to the
rights of either Party against the other accrued or accruing under this Agreement prior to
expiration or termination, including without limitation the obligation to pay royalties for the
Licensed Product sold prior to such expiration or termination. The provisions of Articles 8, 10,
12 and Sections 9.5, 9.6, 11.2.4 and 11.3 shall survive any expiration or termination of this
Agreement. Except as set forth in this Article 11, upon termination or expiration of this
Agreement all other rights and obligations of the Parties under this Agreement cease.

     12. MISCELLANEOUS

     12.1 Assignment. Except as provided in this Section 12.1, this Agreement may not be
assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or
transferred, by either Party without the consent of the other Party. However, either Party may,
without the other Party’s consent, assign this Agreement and its rights and obligations hereunder
in whole or in part to an Affiliate or to a party that acquires, by merger, sale of assets or
otherwise, all or substantially all of the business of the assigning Party to which the subject
matter of this Agreement relates. The assigning Party shall remain responsible for the performance
by its assignee of this Agreement or any obligations hereunder so assigned. An assignment to an
Affiliate shall terminate, and all rights so assigned shall revert to the assigning Party, if and
when such Affiliate ceases to be an Affiliate of the assigning Party.

     12.2 Governing Law. This Agreement shall be construed and the respective rights of
the Parties determined in accordance with the substantive laws of the State of New York,
notwithstanding any provisions of New York law governing conflicts of laws to the contrary, and the
patent laws of the relevant jurisdiction without reference to any rules of conflict of laws or
renvoi.

     12.3 Entire Agreement; Amendments. This Agreement contains the entire understanding
of the Parties with respect to the subject matter hereof, and supersedes all previous arrangements
with respect to the subject matter hereof, whether written or oral. This Agreement (including the
Schedules hereto) may be amended, or any term hereof modified, only by a written instrument
duly-executed by authorized representatives of both Parties hereto.

48

 

     12.4 Severability. If any provision hereof should be held invalid, illegal or
unenforceable in any respect in any jurisdiction, the Parties hereto shall substitute, by mutual
consent, valid provisions for such invalid, illegal or unenforceable provisions, which valid
provisions in their economic effect are sufficiently similar to the invalid, illegal or
unenforceable provisions that it can be reasonably assumed that the Parties would have entered into
this Agreement with such valid provisions. In case such valid provisions cannot be agreed upon,
the invalid, illegal or unenforceable of one or several provisions of this Agreement shall not
affect the validity of this Agreement as a whole, unless the invalid, illegal or unenforceable
provisions are of such essential importance to this Agreement that it is to be reasonably assumed
that the Parties would not have entered into this Agreement without the invalid, illegal or
unenforceable provisions.

     12.5 Headings. The captions to the Articles and Sections hereof are not a part of
this Agreement, but are merely for convenience to assist in locating and reading the several
Articles and Sections hereof.

     12.6 Waiver of Rule of Construction. Each Party has had the opportunity to consult
with counsel in connection with the review, drafting and negotiation of this Agreement.
Accordingly, the rule of construction that any ambiguity in this Agreement shall be construed
against the drafting Party shall not apply.

     12.7 No Implied Waivers; Rights Cumulative. No failure on the part of Alnylam or
Kyowa Hakko to exercise, and no delay in exercising, any right, power, remedy or privilege under
this Agreement, or provided by statute or at law or in equity or otherwise, shall impair, prejudice
or constitute a waiver of any such right, power, remedy or privilege or be construed as a waiver of
any breach of this Agreement or as an acquiescence therein, nor shall any single or partial
exercise of any such right, power, remedy or privilege preclude any other or further exercise
thereof or the exercise of any other right, power, remedy or privilege.

     12.8 Notices. All notices which are required or permitted hereunder shall be in
writing and sufficient if delivered personally, sent by facsimile (and promptly confirmed by

     12.9 Compliance with Export Regulations. Neither Party shall export any technology
licensed to it by the other Party under this Agreement except in compliance with U.S. export laws
and regulations.

     12.10 Force Majeure. Neither Party shall be held liable to the other Party nor be
deemed to have defaulted under or breached this Agreement for failure or delay in performing any
obligation under this Agreement to the extent that such failure or delay is caused by or results
from causes beyond the reasonable control of the affected Party, potentially including without
limitation embargoes, war, acts of war (whether war be declared or not), insurrections, riots,
civil commotions, strikes, lockouts or other labor disturbances, fire, floods, or other acts of
God, or acts, omissions or delays in acting by any governmental authority or the other Party. The
affected Party shall notify the other Party of such force majeure circumstances as soon as
reasonably practical, and shall promptly undertake all reasonable efforts necessary to cure such
force majeure circumstances.

     12.11 Dispute Resolution.

     12.11.1 Disputes. The Parties shall negotiate in good faith and use reasonable
efforts to settle any dispute, controversy or claim arising from, or related to, this Agreement or
to the breach hereof (collectively, “Dispute”). In particular, the Chief Executive Officer of
Alnylam and the Executive Officer of Kyowa Hakko shall attempt to resolve all Disputes. In the
event that the Chief Executive Officer and the Executive Officer cannot reach an agreement
regarding a Dispute, and a Party wishes to pursue the matter, each such Dispute that is not an
“Excluded Claim” shall be finally resolved by binding arbitration under the then-current Rules of
Arbitration of the International Chamber of Commerce (“ICC”) by one or more arbitrators appointed
in accordance with the said Rules and Section 12.11.2 below, and judgment on the arbitration award
may be entered in any court
having jurisdiction thereof. As used in this Section 12.11, the term “Excluded Claim” shall
mean a dispute that concerns (a) the validity or infringement of a patent, trademark or copyright,
or (b) any antitrust, anti-monopoly or competition law or regulation, whether or not statutory.

     12.11.2 Arbitration. The arbitration shall be conducted by a panel of three (3)
persons experienced in the pharmaceutical business who are independent of both Parties and neutral
with respect to the Dispute presented for arbitration. Within thirty (30) days after initiation of
arbitration, each Party shall select one person to act as arbitrator and the two Party-selected
arbitrators shall select a third arbitrator within thirty (30) days of their appointment. If the
arbitrators selected by the Parties are unable or fail to agree upon the third arbitrator, the
third arbitrator shall be appointed by the ICC

50

 

International Court of Arbitration. The place of
arbitration shall be San Francisco, California, USA, and all proceedings and communications shall
be in English.

     Either Party may apply to the arbitrators for interim injunctive relief until the arbitration
award is rendered or the controversy is otherwise resolved. Either Party also may, without waiving
any remedy under this Agreement, seek from any court having jurisdiction any injunctive or
provisional relief necessary to protect the rights or property of that Party pending the
arbitration award. The arbitrators shall have no authority to award punitive or any other type of
damages not measured by a Party’s compensatory damages. Each Party shall bear its own costs and
expenses and attorneys’ fees, and the Party that does not prevail in the arbitration proceeding
shall pay the arbitrators’ and any administrative fees of arbitration. Except to the extent
necessary to confirm an award or as may be required by law, neither a Party nor an arbitrator may
disclose the existence, content, or results of an arbitration without the prior written consent of
both Parties. In no event shall an arbitration be initiated after the date when commencement of a
legal or equitable proceeding based on the dispute, controversy or claim would be barred by the
applicable New York statute of limitations.

     (a) The Parties agree that, in the event of a Dispute over the nature or quality of
performance under this Agreement, neither Party may terminate this Agreement until final resolution
of the Dispute through arbitration or other judicial determination, and this Agreement shall be
terminated only if arbitrators determine that the termination of this Agreement is an appropriate
remedy. The Parties further agree that any payments made pursuant to this Agreement pending
resolution of the Dispute shall be refunded promptly if an arbitrator or court determines that such
payments are not due.

     (b) The Parties hereby agree that any disputed performance or suspended performances pending
the resolution of the arbitration that the arbitrators determine to be required to be performed by
a Party must be completed within a reasonable time period following the final decision of the
arbitrator.

     (c) The Parties hereby agree that any monetary payment to be made by a Party pursuant to a
decision of the arbitrators shall be made in United States dollars, free of any tax or other
deduction. The Parties further agree that the decision of the arbitrators shall be the sole,
exclusive and binding remedy between them regarding determination of the matters presented to the
arbitrator.

     12.12 Independent Contractors. It is expressly agreed that Alnylam and Kyowa Hakko
shall be independent contractors and that the relationship between Alnylam and Kyowa Hakko shall
not constitute a partnership, joint venture or agency. Alnylam shall not have the authority to
make any
statements, representations or commitments of any kind, or to take any action, which shall be
binding on Kyowa Hakko, without the prior written consent of Kyowa Hakko, and Kyowa Hakko shall not
have the authority to make any statements, representations or commitments of any kind, or to take
any action, which shall be binding on Alnylam without the prior written consent of Alnylam.

     12.13 Counterparts. The Agreement may be executed in two or more counterparts, each
of which shall be deemed an original, but all of which together shall constitute one and the same
instrument.

51

 

     12.14 Binding Effect; No Third Party Beneficiaries. As of the Effective Date, this
Agreement shall be binding upon and inure to the benefit of the Parties and their respective
permitted successors and permitted assigns. Except as expressly set forth in this Agreement, no
person or entity other than the Parties and their respective Affiliates and permitted assignees
hereunder shall be deemed an intended beneficiary hereunder or have any right to enforce any
obligation of this Agreement.

SUPPLY AGREEMENT TERMS

1. Alnylam shall be responsible for establishing the specifications, including the necessary

Finished Product to be supplied under the Supply Agreement (the “Specifications”).

2. Until the First Commercial Sale of the Licensed Product in the Kyowa Hakko Territory, Alnylam
shall supply (a) API Bulk Drug Substance and Finished Product to Kyowa Hakko for use in Kyowa
Hakko’s Development activities for the Licensed Product in the Kyowa Hakko Territory conducted in

	•	 	Alnylam is prohibited from granting sublicenses under the Patent Rights to develop, make,
have made, use, sell and import Licensed Products for any diagnostic uses other than for
purposes of therapeutic monitoring.
	 
	•	 	Sublicensees are required to perform their sublicense agreement in accordance with the Max
Planck US License Agreement. If Max Planck determines that Alnylam or any of its Sublicencees
has failed to fulfill any of its obligations under Section 4 (Company Diligence Obligations
and Report) of the Max Planck US License Agreement, then Max Planck may treat such failure as
a material breach.
	 
	•	 	If any license granted to Alnylam under the Max Planck US License Agreement is terminated,
any sublicense under such license granted prior to termination of said license will remain in
full force and effect, provided that (i) the Sublicensee is not then in breach
of its sublicense agreement; and (ii) the Sublicensee agrees to be bound to Max Planck as
licensor under the terms and conditions of the sublicense agreement, provided that Max Planck
will have no other obligation than to leave the sublicense granted by Alnylam in place.

63

 

	•	 	Immediately after the signature of each sublicense granted under the Max Planck US License
Agreement, Alnylam is required to provide Max Planck with a copy of the signed sublicense
agreement.

Diligence and Reporting (Sections 4.1 and 4.2; Sections 1 and 3 of Requirement Amendment)

	•	 	Sublicensees are required to use commercially reasonable efforts to develop and to
introduce into the commercial market Licensed Products at the earliest practical date.
	 
	•	 	Sublicensees are required to furnish information to Alnylam for inclusion in its reports to
Max Planck, which reports are due within 30 days after the end of each calendar quarter with
Alnylam’s standard R&D report, on the progress of its efforts during the immediately preceding
calendar quarter to develop and commercialize Licensed Products for each indication and
sub-indication within the Field. The report shall also contain a discussion of intended R&D
efforts for the calendar quarter in which the report is submitted.

Royalty Payment Obligation (Sections 5.2 and 5.3)

	•	 	The following running royalties are payable to Max Planck by Alnylam on Net Sales of
therapeutic and prophylactic Licensed Products by Alnylam and its Sublicensees:

	 	(i)	 	[**]% of the first US$[**] of annual accumulated Net Sales of all Licensed
Products;
	 
	 	(ii)	 	[**]% of annual accumulated Net Sales of all Licensed Products between US$[**]
and US$[**];
	 
	 	(iii)	 	[**]% of annual accumulated Net Sales of all Licensed Products between US$[**]
and US$[**];
	 
	 	(iv)	 	[**]% of annual accumulated Net Sales of all Licensed Products between US$[**]
and US$[**];
	 
	 	(v)	 	[**]% of annual accumulated Net Sales of all Licensed Products between US$[**]
and US$[**]; and
	 
	 	(vi)	 	[**]% of annual accumulated Net Sales of all Licensed Products above US$[**].

	•	 	If the sale of any Licensed Product is covered by more than one of the Patent Rights, multiple royalties shall not be
due. Alnylam or a Sublicensee develops diagnostic Licensed Products, Alnylam will initiate negotiations with Max
Planck at least [**] prior to the intended first commercial sale of each diagnostic Licensed Product. Alnylam and Max
Planck will negotiate in good faith [**] for such
diagnostic Licensed Product.

	 
	•	 	Non-cash consideration will not be accepted by any Sublicensee for Licensed Products without the prior written consent
of Max Planck.

	 
	•	 	If any Sublicensee takes, for objective commercial and/or legal reasons, a license from any third party under any
patent applications or patents that dominate the Patent Rights or is dominated by the Patent Rights in order to
develop, make, use, sell or import any Licensed Product (explicitly excluding, without limitation, any third party
patents and patent applications for formulation, stabilization and delivery), then up to [**]% of any additional
running royalties to be paid to such

64

 

	 	 	third party may be deducted, up to [**]% of the running royalties stated in Section 5.2 of the
Max Planck US License Agreement, from the date such running royalties must be paid to such third
party. However, the running royalties stated in Section 5.2 of the Max Planck US License
Agreement will not be reduced to less than a minimum of [**]% of Net Sales in any case. No
deduction is allowed from running royalties due to Max Planck for any license fees for patents
and patent applications for formulation stabilization and delivery. For avoidance of doubt, if
a Sublicensee takes a license to a third party target, in no event is a deduction allowed on any
license fees for such target from running royalties due to Max Planck under the Max Planck US
License Agreement.

	•	 	If (i) Sublicensees sell a Licensed Product in a country where no Patent Rights are issued
and no patent applications that are part of the Patent Rights are pending that have not been
pending for less than [**] after filing national patent applications in the country in
question, and (ii) such Licensed Product is manufactured in a country where Patent Rights are
issued or patent applications that are part of the Patent Rights are pending that have not
been pending for more than [**] after filing national patent applications in the country in
question, the royalties stated in Section 5.2 of the Max Planck US License Agreement will be
reduced by [**]% for such Licensed Product, until the expiration or abandonment of all issued
patents and filed patent applications within the Patent Rights in the country in which the
Licensed Product is manufactured.

Payments and Reports (Sections 5.4 and 5.5)

	•	 	Within 30 days after the end of each calendar half year, Alnylam is required to deliver a
detailed report to Max Planck for the immediately preceding calendar half year showing at
least (i) the number of Licensed Products sold by Alnylam and its Sublicensees in each
country, (ii) the gross price charged by Alnylam and its Sublicensees for each Licensed
Products in each country, (iii) the calculation of Net Sales, and (iv) the resulting running
royalties due to Max Planck according to those figures. If no running royalties are due to
Max Planck, the report shall so state.

	•	 	Running royalties shall be payable for each calendar half year, and shall be due to Max
Planck within 60 days after the end of each calendar half year.

Bookkeeping and Auditing (Sections 5.6 and 5.7)

	•	 	Sublicensees are obliged to keep complete and accurate books on any reports and payments
due to Max Planck under the Max Planck US License Agreement, which books shall contain
sufficient information to permit Max Planck to confirm the accuracy of any reports and
payments made to Max Planck. Upon Max Planck’s request, Alnylam, or agents appointed by Max
Planck for Alnylam, shall check the books of its Sublicensees for Max Planck, once a year.
This right of auditing by Max Planck shall expire five years after each report or payment has
been made. Alnylam shall have the right to check the books of its Sublicensees according to
Section 5.6. All payments made by Sublicensees under the Max Planck US License Agreement are
nonrefundable and noncreditable against each other.

Prosecution and Enforcement (Article 6)

	•	 	The Owners have the first right to prosecute the Patent Rights. If all Owners wish to
cease prosecution or abandon any of the Patent Rights, Alnylam will have the right to continue

65

 

	 	 	prosecution or maintenance of such Patent Rights in its discretion, in its name and at its
expense. Max Planck will inform and offer Alnylam Europe AG, respectively. If Alnylam does not
accept Max Planck’s offer within 30 days after receiving it, the Owners will be free to cease
prosecution or abandon such Patent Rights.

	•	 	The Owners will have the right, but not the obligation, to prosecute in their own
discretion and at their own expense, all infringements of the Patent Rights. The total cost
of any such sole infringement action will be borne by the Owners, and the Owners will keep any
resulting recovery or damages. In any such infringement suits, Alnylam will, at the Owners’
expense, cooperate in all respects.

	•	 	Alnylam will have the right to join the Owners’ prosecution of any infringements of the
Patent Rights. In any such joint infringement suits, the Owners and Alnylam will cooperate in
all respects. The Owners and Alnylam will agree in good faith on the sharing of the total
cost of any such joint infringement action and the sharing of any recovery or damages derived
therefrom.

	•	 	If the Owners decide not to prosecute infringements of the Patent Rights, neither solely
nor jointly with Alnylam, Max Planck will offer to Alnylam to prosecute any such infringement
in its own discretion and at its own expense. Max Planck will offer Alnylam Europe AG
respectively. The Owners will, at Alnylam’s expense, cooperate. The total cost of any such
sole infringement action will be borne by Alnylam, and Alnylam will keep any resulting
recovery or damages.

Certain Termination Rights (Sections 11.2, 11.3 and 11.5)

	•	 	Alnylam has the right to terminate the Max Planck US License Agreement for any reason upon
at least 6 months’ prior written notice to Max Planck and payment of all amounts due to Max
Planck through the effective date of termination.

	•	 	If Alnylam ceases to carry on its business related to the Max Planck US License Agreement,
Alnylam must inform Max Planck immediately. Alnylam and Max Planck have the right to
terminate the agreement immediately upon written notice to the other.

	•	 	To the extent legally enforceable, if any Sublicensee attacks, or has attacked or supports
an attack through a third party, the validity of any of the Patent Rights, Alnylam will have
the right to terminate the sublicense agreement immediately; upon request of Max Planck,
Alnylam will have the obligation to terminate such sublicense agreement.

Licence Agreement between Cancer Research Technology Ltd. (“CRT”) and Alnylam, dated July
18, 2003 (“CRT Agreement”)

Brief Summary of Technology Covered by License:

CRT granted Alnylam exclusive rights to develop and commercialize RNAi therapeutics under certain
patent rights relating to “Inhibiting Gene Expression with dsRNA”.

Scope of License Grant (Sections 2.1 — 2.3, 2.5)

	•	 	The license granted to Alnylam and its Affiliate(s) is limited to an exclusive, worldwide
license in the Field under the CRT Patent Rights to research, develop, have developed, use,
keep, make, have made, import, have imported, sell, have sold and otherwise dispose or offer
to dispose of Licensed Products. Except as necessary for the development and/or sale of
Licensed Products in the Field, Alnylam does not have rights to make use of the CRT Patent
Rights for any diagnostic application, as research tools or reagents, for target validation,
or for small molecule drug discovery.
	 
	•	 	CRT and Cancer Research UK have the right to use, and CRT has the right to consent to the
use by academic research institutions (including for the sake of clarity those in receipt of
Cancer Research UK funding) of, the CRT Patent Rights in the Field for internal, or in
collaboration with another academic research institution, non-commercial, non-commercially
sponsored research. For the sake of clarity, Cancer Research UK-funded Researchers are
permitted under the CRT Patent Rights to conduct clinical trials of potential dsRNA
therapeutic agents as part of their Cancer Research UK-funded academic research.
	 
	•	 	CRT grants an option to Alnylam and its Affiliates to enter into non-exclusive,
non-sublicenseable and non-assignable licenses under the CRT Patent Rights in the fields of
either or both of [**] and [**] on terms to be agreed in good faith between CRT and Alnylam,
the payment terms in respect of each license which shall be no more than annual payments of
[**] pounds sterling (£[**]) or any (lesser) sum that may be agreed between CRT and a Third
Party licensee after the Commencement Date in the same field (other than a license pursuant to
which, or under the terms of a related agreement, significant resources are provided by the
Third Party in respect of a collaboration in the field).

Restrictions on Sublicensing by Alnylam (Section 2.4)

	•	 	Any Sub-license entered into by Alnylam must be limited to the Field and contain
restrictions in equivalent terms to those set out in Clause 2.1 of the CRT Agreement.
	 
	•	 	Any Sub-license shall terminate automatically on the expiry or termination for whatever
reason of the CRT Agreement. If the CRT Agreement is terminated pursuant to Clause 10 of the
CRT Agreement, CRT has agreed to enter into a direct licensing arrangement with any
Sub-licensee on terms substantially similar to those contained in the CRT Agreement save that
any license granted by CRT to any Sub-licensee shall be consistent with the terms of the
Sub-license granted by Alnylam (or its Affiliate) in relation to field, territory,
exclusivity, rights to sub-license and payment provisions. However, if the CRT Agreement is
terminated by Alnylam pursuant to Clause 10.2 of the CRT Agreement, the foregoing shall apply
save that the granting of such license by

73

 

	 	 	CRT shall be subject to CRT’s consent. Nothing in Clause 2.4 of the CRT Agreement shall confer
upon CRT any obligation to enter into a direct licensing arrangement with the Sub-licensee where
the Sub-licensee is in default of its obligations under the Sub-license. CRT shall not be
expected to take any responsibility for any disputes between Alnylam (or its Affiliate) and its
Sub-licensees relating to the terms of the Sub-license(s) and notwithstanding the foregoing, CRT
shall not be obliged to enter into a direct license with a Sub-licensee in circumstances in
which the Sub-licensee reserves any right to maintain a claim against CRT where such claim was
previously maintained against Alnylam (or its Affiliate).
	 
	•	 	Sublicensees are required to undertake to CRT directly to allow the same access to the
books and records as CRT has to Alnylam’s books and records under the CRT Agreement.
	 
	•	 	Sublicensees are restricted with respect to rights to assign in equivalent terms to those
set out in Clause 15 of the CRT Agreement and any further sublicensing must be subject to the
terms of Clause 2.4 of the CRT Agreement.
	 
	•	 	Alnylam or its Affiliate shall (subject to Alnylam’s and its Affiliate’s right to redact
confidential information not related to CRT’s rights hereunder) provide to CRT in confidence a
copy of each and every Platform Sub-license entered into.

Royalty Payment Obligation (Sections 3.2.1 and 3.3)

	•	 	Royalties of [**]% of Net Sales of Royalty Licensed Products in the Field are payable to
CRT.
	 
	•	 	If at any time prior to or during the period for the payment of royalties under the CRT
Agreement in relation to any particular territory, a Sub-licensee elects in its reasonable
opinion to take a license from a Third Party to any Blocking IP to develop, make, sell, or
otherwise dispose of Licensed Products, the royalties set forth in Clause 3.2.1 shall be
reduced by [**]% of the amount paid to such Third Party to access said Blocking IP. In no
event shall the royalty payable to CRT be reduced below [**]%.

Royalty Reports and Payment (Sections 4.2.1 and 5.1)

	•	 	Royalty payments are required to be made to CRT within 30 days of the end of the Quarter in
which sales of the relevant Licensed Products took place.

Alnylam or its Affiliate or the grant of a Sub-license, Alnylam is required to prepare an
annual statement showing all monies due to CRT under the CRT Agreement for the previous
calendar year, on a country by country basis. The statement shall include the number of units
of each Royalty Licensed Product sold in each country in which sales occurred, and shall be
submitted to CRT within 60 Business Days of March 31st of each year. If CRT gives notice
pursuant to the CRT Agreement that it does not accept the statement, Alnylam shall make
available to an independent accountant all books and records required for the purpose of
certifying such statement.

Books and Records (Section 5.2)

74

 

	•	 	Sub-licensees are required to keep true and accurate records and books of account
containing all data necessary for calculating amounts payable to CRT. Such records and books
of account shall be kept for 5 years following the end of the calendar year to which they
relate, and shall, upon reasonable notice having been given by CRT, be open at all reasonable
times on Business Days for inspection by an independent firm of accountants.

Diligence and Reporting (Article 6)

	•	 	Alnylam shall use reasonable efforts to develop, make, market, sell, and otherwise dispose
of Licensed Products in all therapeutic areas within the Field and market each Licensed
Product in the Field throughout the United States, Europe and Japan.
	 
	•	 	CRT shall provide notice to Alnylam of its knowledge of a willing potential sub-licensee.
Without prejudice to Clause 6.1 of the CRT Agreement, in the event that Alnylam (itself or
through Affiliates or Sub-licensees) declines to develop, make, market, sell or otherwise
dispose of Licensed Products in any therapeutic area or any indication within the cancer
therapeutic area within the Field or any territory within the Territory in the Field, Alnylam
shall (save as hereinafter provided) upon direct approach made by, or receipt of notice from
CRT of a willing potential sublicensee in respect of a Licensed Product that has demonstrated
clinical efficacy be obliged to enter into negotiations in good faith with such Third Party to
enter into a Sub-license in relation to such therapeutic area, indication, or territory. The
preceding provisions of Clause 6.2 of the CRT Agreement shall not apply in respect of any
therapeutic area, indication, or territory in respect of which Alnylam provides to CRT’s
reasonable satisfaction evidence that the conclusion of a Sub-license would:
	 
	•	 	(a) be contrary to sound and reasonable business practice applicable to pharmaceutical
development; or
	 
	•	 	(b) not materially increase the availability of therapeutic products covered by the CRT
Patent Rights.
	 
	•	 	If CRT believes that Alnylam has failed to meet the diligence requirements set forth in
Clause 6 of the CRT Agreement, but Alnylam fails to reestablish diligence within [**] of
receipt of notice from CRT, CRT’s remedy is limited to, at CRT’s discretion, termination of
Alnylam’s license under the CRT Patent Rights in the particular territory or therapeutic area
or, with respect to Clause 6.2 of the CRT Agreement, indication within the cancer therapeutic
area for which Alnylam has failed to meet the diligence requirements. For the sake of
clarity, should Alnylam’s license be terminated in respect of a therapeutic area or territory
pursuant to Clause 6.3 of the CRT Agreement, CRT shall be free to offer such therapeutic area
or territory to a potential licensee.
	 
	•	 	Within 30 days of the end of each Year, Alnylam shall provide CRT with a written report of
the steps taken by Alnylam, its Affiliates and Sub-licensees to comply with the performance
obligations of Clause 6.1 and Clause 6.2 of the CRT Agreement. Alnylam’s annual statement
shall also include a detailed description of therapeutic areas and territories under
development and an overview of Alnylam’s development plans for the forthcoming year (itself or
through Affiliates or Sub-licensees).

75

 

	•	 	If Alnylam intends to undertake a Phase I Clinical Trial of any Licensed Product in the UK,
Alnylam shall, at its option, notify CRT with the particulars of the proposed investigation,
and allow Cancer Research UK the opportunity of conducting or procuring the conduct of the
investigation on behalf of Alnylam or participate in such an investigation, subject to the
agreement of terms acceptable to Alnylam, CRT and Cancer Research UK.

Prosecution and Enforcement (Sections 7.1, 7.2, 7.4 and 7.5)

	•	 	CRT shall or shall procure in consultation with and (except as set forth in Clause 7.2) at
the reasonable expense of Alnylam the filing, prosecution, and maintenance of any patents and
patent applications comprised within the CRT Patent Rights. Alnylam shall bear (except as set
forth in Clause 7.2) the full expense and shall reimburse in full and hold CRT harmless in
respect of any and all reasonable fees, charges, costs, levies or expenses incurred by CRT or
its agents after the Commencement Date in relation to such applications.
	 
	•	 	The reasonable costs of opposition and interference proceedings in relation to the CRT
Patent Rights (together “Challenges”) shall be borne equally by the Parties. In the
event that the total aggregate costs of Challenges in any year exceed $[**], CRT shall be free
to make no further contribution to the costs of Challenges and all further costs incurred
during that year (“Further Challenge Costs”) and, at Alnylam’s option, the future
control of such Challenge(s) shall be borne by Alnylam solely. CRT shall give credit for
[**]% of Further Challenge Costs actually paid by Alnylam against sums due from Alnylam to CRT
pursuant to Clause 3 of the CRT Agreement from that time forward. In the event that one or
more of the CRT Patent Rights are the subject of a declaration of interference by the USPTO as
interfering with claims in a patent or patent application which is owned by or licensed by
Alnylam or its Affiliate, CRT and Alnylam shall negotiate in good faith to reasonably agree on
a mechanism outside the USPTO which simplifies the issues involved in determining priority and
which awards priority to the appropriate party to the interference.
	 
	•	 	In any country where Alnylam elects not to have a patent application included in CRT Patent
Rights filed or to pay expenses associated with filing, prosecuting, interference or
equivalent proceedings, or maintaining a patent application or patent included in CRT Patent
Rights, CRT may file, prosecute, continue with interference or equivalent proceedings, and/or
maintain such patent application or patent at its own expense and for its own exclusive
benefit and Alnylam (and its Affiliates) thereafter shall not be licensed under such patent or
patent application. For the sake of clarity, should Alnylam elect not to continue with
interference or equivalent proceedings and CRT elect to continue with such proceedings,
Alnylam (and its Affiliates) shall cease to be licensed for the patent subject to interference
for that territory.
	 
	•	 	Alnylam shall, at its option and at its own cost, defend and enforce or shall procure the
defense or enforcement of the rights under the CRT Patent Rights. If Alnylam opts not to
defend or enforce the relevant CRT Patent Rights, Alnylam shall grant to CRT (if CRT so
requests) any and all rights that would be necessary for CRT to undertake the enforcement or
defense. If Alnylam is unable to grant such rights, then it shall, at CRT’s request, grant to
CRT the right to conduct such an action in its name. Alnylam shall provide, at CRT’s request
and CRT’s reasonable expense, such reasonable assistance as CRT may reasonably request in any
such proceedings.

76

 

Termination for Patent Challenge (Section 10.5)

	•	 	CRT may terminate the CRT Agreement upon 30 days’ written notice to Alnylam if Alnylam or
its Affiliate commences legal proceedings, with the exception of interference proceedings
declared by the USPTO or any other patent office, contesting the validity of the CRT Patent
Rights; or commences itself, or provides any material assistance to a Third Party in relation
to, legal proceedings contesting the ownership of the CRT Patent Rights. Any actions taken
concerning determination of priority of invention under US patent law between a CRT Patent
Right and claims in a patent or patent application which is owned by or licensed by Alnylam or
its Affiliate shall not be considered a contest of validity or ownership under Clause 10.5 of
the CRT Agreement.

Termination by Alnylam at Will (Section 10.2)

	•	 	Alnylam may terminate the CRT Agreement by written notice to CRT, and the CRT Agreement
will terminate 90 days after receipt by CRT of such notice

Definitions:

“Blocking IP” means any and all Patent Rights (other than that licensed under the CRT Agreement)
which, if claims covering subject matter of such Patent Rights issue, would render the use,
development, manufacture, sale, or other disposal of a Licensed Product unlawful in the absence of
a license to such Patent Rights from a Third Party.

“CRT Patent Rights” means the patent applications referred to in Schedule 1 (entitled “Inhibiting
Gene Expression with dsRNA”) and all Patent Rights deriving priority from them and all Patent
Rights deriving priority from such Patent Rights.

“Field” means the development of RNAi therapeutic products for the treatment of human disease
(including by means of gene therapy).

“Licensed Products” means product or products which, or the process of production of which, or the

STANFORD

Agreement between the Board of Trustees of the Leland Stanford Junior University
(“Stanford”) and Alnylam, dated September 17, 2003 (“Stanford Agreement”)

Brief Summary of Technology Covered by License:

Stanford granted Alnylam co-exclusive rights under an invention relating to “Efficient RNA
Transfection in the Livers of Living Mice” from the laboratory of Mark Kay, and certain patent
rights relating to [**] for the delivery of ex-vivo synthesized siRNA Molecules for research,
development and therapeutic uses.

Limitations on Scope of License (Articles 3 and 4; Sections 6.10, 13.2 and 13.7)

	•	 	The license granted to Alnylam is limited to a worldwide license under the Invention and
Licensed Patents in the Licensed Field of Use to make, have made, use, have used, sell, have
sold, import, and have imported Licensed Product.
	 
	•	 	The license to Alnylam is Co-Exclusive, including the right to sublicense in the Licensed
Field of Use. If the other Co-Licensee discontinues licensing this Field of Use, then the
Field of Use will become exclusive for Alnylam. If the other Co-Licensee discontinues any
other therapeutic license under the Licensed Patents, Stanford will so inform Alnylam and
Alnylam will have the option to obtain an exclusive, worldwide sublicensable license to such
therapeutic field. The terms of any such license will be negotiated in good faith by Stanford
and Alnylam. This option may be exercised by Alnylam by written notice to Stanford at any
time during a period of 90 days after notification by Stanford.
	 
	•	 	Stanford may practice the Invention and use the Technology for its own bona fide research,
including sponsored research and collaborations. Stanford has the right to publish any
information included in the Technology and Licensed Patents.
	 
	•	 	The Stanford Agreement is subject to all of the terms and conditions of Title 25 USC
200-204, including an obligation that Licensed Product sold or produced in the U.S. be
“manufactured substantially in the U.S.” Alnylam will take all reasonable action necessary on
its part as licensee to enable Stanford to satisfy its obligations to the U.S. Government
under Title 35.
	 
	•	 	If Alnylam or its sublicensee(s) is unable or unwilling to serve or develop a potential
market or market territory for which there is a willing sublicensee, Alnylam will, at
Stanford’s request, negotiate in good faith a sublicense under the Licensed Patents, provided
that the same request has been made of the other Co-Exclusive licensee. Bona fide business
concerns of Alnylam will be considered in any good faith negotiations for a sublicense under
the Stanford Agreement and Alnylam will not be required to license/sublicense any other
intellectual property to such sublicensee. If the other Co-Exclusive licensee itself or
through its sublicensees is already developing a product in the market or market territory for
which there is a willing sublicensee, Alnylam will not be required to sublicense to such
party. If any other issue arises in the context of such required sublicensing, Stanford will
discuss and try to resolve such issue with Alnylam in good faith.

80

 

	•	 	Alnylam may grant royalty-free or noncash sublicenses or cross-licenses only if Alnylam
pays all royalties due Stanford from sublicensee’s Net Sales.

Diligence and Reporting (Article 5)

	•	 	Alnylam is required to use all commercially reasonable efforts and diligence to develop,
manufacture, and sell or lease Licensed Product and to diligently develop markets for the
Licensed Product. In particular, Alnylam is required to meet the following milestones, which
will satisfy Alnylam’s diligence obligations: (1) By the end of the year 2005, Alnylam will
select the method of delivery. (2) By the end of the year 2006, Alnylam will optimize the
lead. (3) By the end of the year 2008, Alnylam will conclude preclinical development. If
Alnylam in good faith fails to meet a milestone set forth above, and Alnylam fails to
reestablish diligence within [**], Stanford may terminate the Stanford Agreement. Stanford
may also terminate the Stanford Agreement if Alnylam has not sold Licensed Product for any
[**] period after Alnylam’s first commercial sale of Licensed Product. Efforts of Alnylam’s
sublicensees or Affiliates will be considered efforts of Alnylam.
	 
	•	 	On or before September 30 of each year until Alnylam markets a Licensed Product, Alnylam is
required to make a written annual report covering the preceding year ending June 30, regarding
progress toward commercialization of Licensed Product. The report must include, as a minimum,
information (e.g., summary of work completed, key scientific discoveries, summary of work in
progress, current schedule of anticipated events or milestones and market plans for
introduction of Licensed Product) sufficient to enable Stanford to satisfy reporting
requirements of the U.S. Government, and for Stanford to ascertain progress by Alnylam toward
meeting the diligence requirements of Article 5 of the Stanford Agreement.

Royalty Payment Obligation (Article 6)

	•	 	On each anniversary of the Effective Date, a minimum yearly royalty of $[**] must be paid
to Stanford, which payments are non-refundable but creditable against earned royalties to the
extent provided in Section 6.4.
	 
	•	 	Earned royalties of [**]% of Net Sales for Licensed Product are payable to Stanford,
subject to the following:

	 	(i)	 	Royalty Payments are reduced up to [**]% (from [**]% of Net Sales down to [**]%
of Net Sales) by the amount of royalty paid to access additional intellectual property
necessary in order to sell Licensed Products (“Additional Earned Royalties”).
	 
	 	(ii)	 	Such royalty payments shall be reduced as follows:

	 	(1)	 	[**]% if Additional Earned Royalties are [**]% or less.
	 
	 	(2)	 	[**]% if Additional Earned Royalties are greater than [**]% but
less than [**]%.
	 
	 	(3)	 	[**]% if Additional Earned Royalties are equal to or greater than
[**]% but less than [**]%.

81

 

	 	(4)	 	[**]% if Additional Earned Royalties are equal to or greater than
[**]% but less than [**]%.
	 
	 	(5)	 	[**]% if Additional Earned Royalties are equal to or higher than
[**]%.

	 	(iii)	 	Only one royalty is due on each Licensed Product, regardless of whether its
manufacture, use, importation, or sale is covered by more than one patent or patent
application included in Licensed Patents, and no further royalties will be due for use
of such Licensed Product by Alnylam or its sublicensee’s customers.

	•	 	Creditable payments under the Stanford Agreement will be an offset against each earned
royalty payment which is required to be paid under Section 6.3 until the entire credit is
exhausted.
	 
	•	 	If the Stanford Agreement is not terminated in accordance with other provisions, royalties
must continue to be paid on all Licensed Products that are either sold or produced under the
license granted in Article 3, whether or not such Licensed Products are produced before the
Effective Date or sold after the Licensed Patents have expired.

Restrictions on Sublicensing by Alnylam (Sections 13.1, 13.3-13.5 and 13.7)

	•	 	Alnylam may grant sublicenses in the Co-exclusive Licensed Field of Use during the
Co-Exclusive period (a) only in conjunction with intellectual property under Alnylam’s
control; and (b) only if Alnylam is developing or selling Licensed Products in the
Co-Exclusive Licensed Field of Use.
	 
	•	 	Any sublicense granted by Alnylam under the Stanford Agreement must be subject and
subordinate to the terms and conditions of the Stanford Agreement.
	 
	•	 	Any sublicense will expressly include the provisions of Articles 7 (Royalty Reports,
Payments and Accounting), 8 (Negation of Warranties) and 9 (Indemnity) for the benefit of
Stanford.
	 
	•	 	If a sublicensee desires that its sublicense survive the termination of the Stanford
Agreement, Stanford has agreed that the sublicense will revert to Stanford subject to the
transfer of all obligations, including the payment of royalties specified in the sublicense,
to Stanford or its designee, if the Stanford Agreement is terminated.
	 
	•	 	Alnylam will provide Stanford in confidence a copy of all relevant portions of any
sublicenses granted under the Stanford Agreement.

Restrictions on Further Sublicensing by Sublicensee (Section 13.3)

	•	 	Sublicensees may not further sublicense, except that Sublicensees may further sublicense
rights under Licensed Patents only as needed or implied in the course of distribution or
performance of service as required for the sale to an end user of Licensed Products.

Royalty Reports, Payments, and Accounting (Article 7)

	•	 	Beginning with the first sale of a Licensed Product, Alnylam is required to make written
reports (even if there are no sales) and earned royalty payments within 30 days after the end
of each calendar quarter. The report must be in the form of Appendix B to the
Stanford Agreement and state the number, description, and aggregate Net Sales of Licensed
Product during the completed

82

 

	 	 	calendar quarter, and calculation of earned royalty payment due. With each report, royalty
payments due for the completed calendar quarter must be paid.

	•	 	A written report is due within 90 days after the license expires under Section 3.2 of the
Stanford Agreement. Alnylam is required to continue to make reports after the license has
expired, until all Licensed Product produced have been sold or destroyed. Royalty payments
must also continue to be made, concurrent with the submittal of each post-termination report.
	 
	•	 	Records must be kept and maintained for 3 years showing the manufacture, sale, use, and
other disposition of products sold or otherwise disposed of under the license, including
general-ledger records of cash receipts and expenses, as well as other information sufficient
to determine royalties due, including production records, customers, and serial numbers, and
related information in sufficient detail to enable Alnylam to determine the royalties payable
under the Stanford Agreement.
	 
	•	 	An independent certified public accountant selected by Stanford and acceptable to Alnylam
is permitted to examine such books and records from time to time (but no more than once a
year) to the extent necessary to verify the royalty and termination reports as detailed in the
Stanford Agreement.

Prosecution and Enforcement (Section 6.9; Article 12)

	•	 	Stanford will be responsible for the filing, prosecution and maintenance of the Licensed
Patents. Throughout the term of the Stanford agreement, Alnylam will retain rights to any
claims that have support in the Licensed Patents, whether or not they are in a CIP. If
Stanford elects not to continue to seek or maintain patent prosecution on any Licensed Patent
in any country during the co-exclusive term despite Alnylam’s willingness to pay its share of
the prosecution costs, Alnylam will have the right, at its expense, to procure, maintain and
enforce in any country such Licensed Patent.
	 
	•	 	Stanford, Alnylam and the other Co-Exclusive licensee will meet to discuss any suspected
infringement of any Licensed Patent by a third party during the Co-Exclusive period of the
Stanford Agreement. If the Field-of-Use becomes Exclusive for Alnylam, Stanford and Alnylam
will meet to discuss the matter during the Exclusive period of the Stanford Agreement.
	 
	•	 	If Stanford does not choose to institute suit against said third party within 60 days of
notification, then the suit may be brought in both Alnylam’s and the other Co-Exclusive
licensee’s names, and Stanford’s name if necessary, and Alnylam and Co-Exclusive licensee will
share equally the out-of-pocket costs thereof and any recovery or settlement. In such
situation, Alnylam and the other Co-Exclusive licensee will agree to the manner in which they
exercise control over such action and if either party desires to also be represented by
separate counsel of its own selection, such party will pay the fees for such counsel.
	 
	•	 	If both Stanford and the other Co-Exclusive licensee, or Stanford if there is no other
Co-Exclusive Licensee, choose not to institute suit against said third party within 60 days of
notification, then Alnylam will have the right to institute suit in its own name or if
necessary, in Stanford’s name, to enjoin such infringement. Alnylam will bear the entire cost
of such litigation and will be entitled to

83

 

	 	 	retain the entire amount of any recovery or settlement. However, any recovery in excess of
litigation/settlement costs will be considered Net Sales and Alnylam must pay Stanford royalties
as indicated in Article 6 of the Stanford Agreement.

Negation of Warranties (Article 8)

	•	 	Stanford has represented and warranted to Alnylam that, to the best of Stanford’s OTL
knowledge, Stanford is the sole owner of Stanford Licensed Patents and has the right to enter
into the Stanford Agreement and to grant the rights and licenses set forth therein.
	 
	•	 	Notwithstanding the foregoing, nothing in the Stanford Agreement or any sublicense
agreement shall be construed as:

(i) Stanford’s warranty or representation as to the validity or scope of any Licensed
Patent;

(ii) A warranty or representation that anything made, used, sold, or otherwise disposed of
under any license granted under the Stanford Agreement or any sublicense agreement is or
will be free from infringement of patents, copyrights, and other rights of third parties;

(iii) An obligation to bring suit against third parties for infringement, except as
described in Article 12 of the Stanford Agreement;

(iv) Granting by implication, estoppel, or otherwise any licenses or rights under patents or
other rights of Stanford or other persons other than Licensed Patents, regardless of whether
the patents or other rights are dominant or subordinate to any Licensed Patents; or

(v) An obligation to furnish any technology or technological information.

Except as expressly set forth in the Stanford Agreement, it is acknowledged and agreed that
Stanford makes no representations and extends no warranties of any kind, either express or
implied. There are no express or implied warranties of merchantability or fitness for a
particular purpose, or that Licensed Products will not infringe any patent, copyright,
trademark, or other rights, or any other express or implied warranties.

	•	 	Nothing in the Stanford Agreement or any sublicense agreement grants any sublicensee any
express or implied license or right under or to U.S. Patent 4,656,134 entitled “Amplification
of Eucaryotic Genes” or any patent application corresponding thereto.

Indemnification and Insurance (Article 9)

	•	 	Alnylam is required to indemnify, hold harmless, and defend Stanford and Stanford Hospitals
and Clinics, and their respective trustees, officers, employees, students, and agents against
all claims for death, illness, personal injury, property damage, and improper business
practices arising out of the manufacture, use, sale, or other disposition of Invention,
Licensed Patents, Licensed Products, by Alnylam or any sublicensee, or their customers except
to the extent such claims are due to the gross negligence or willful misconduct of Stanford.
Upon notification to Alnylam in writing of any such claim, Alnylam shall manage and control,
at its own expense, the defense of such claim and its settlement. Alnylam agrees not to settle
any such claim against Stanford without Stanford’s written consent where such settlement would
include any admission of liability on the part of Stanford, where the settlement would impose
any restriction on the conduct by Stanford of any of

84

 

	 	 	its activities, or where the settlement would not include an unconditional release of Stanford
from all liability for claims that are the subject matter of such claim.

	•	 	Subject to Section 9.1, neither Stanford nor Alnylam shall be liable to each other for any
loss profit, expectation, punitive or other indirect, special, consequential, or other damages
whatsoever, in connection with any claim arising out of or related to the Stanford Agreement
whether grounded in tort (including negligence), strict liability, contract, or otherwise.
	 
	•	 	Alnylam shall at all times comply, through insurance or self-insurance, with all statutory
workers’ compensation and employers’ liability requirements covering all employees with
respect to activities performed under the Stanford Agreement.
	 
	•	 	Alnylam shall maintain, during the term of the Stanford Agreement, Comprehensive General
Liability Insurance, including Product Liability Insurance prior to commercialization, with a
reputable and financially secure insurance carrier to cover the activities of Alnylam and its
sublicensees. Upon initiation of human clinical trials of any Licensed Product, such insurance
will provide minimum limits of liability of Five Million Dollars and will include Stanford and
Stanford Hospitals and Clinics, and their respective trustees, directors, officers, employees,
students, and agents as additional insureds. Insurance will be written to cover claims
incurred, discovered, manifested, or made during or after the expiration of the Stanford
Agreement and must be placed with carriers with ratings of at least A- as rated by A.M. Best.
Alnylam will furnish a Certificate of Insurance evidencing primary coverage and additional
insured requirements and requiring thirty (30) days prior written notice of cancellation or
material change to Stanford. Alnylam will advise Stanford, in writing, that it maintains
excess liability coverage (following form) over primary insurance for at least the minimum
limits set forth above. All insurance of Alnylam will be primary coverage; insurance of
Stanford and Stanford Hospitals and Clinics will be excess and noncontributory.

Certain Termination Rights (Section 14.1)

	•	 	Alnylam has the right to terminate the Stanford Agreement by giving Stanford at least 30
days’ prior written notice.

Alnylam and Kyowa Hakko Form Alliance for the Development and Commercialization of ALN-RSV01 in
Asia

-ALN-RSV01, Alnylam’s Lead RNAi Therapeutic, is in Phase II Clinical Development for Treatment of

Respiratory Syncytial Virus (RSV) Infection -

CAMBRIDGE, Mass., USA and TOKYO, Japan, June 19, 2008 — Alnylam Pharmaceuticals, Inc. (Nasdaq:
ALNY) and Kyowa Hakko Kogyo Co., Ltd. (TSE: 4151) today announced that they have formed an
exclusive alliance to develop and commercialize ALN-RSV01, an RNAi therapeutic in Phase II clinical
development by Alnylam for the treatment of respiratory syncytial virus (RSV) infection, in Japan
and other major markets in Asia.

Under the terms of the collaboration, Kyowa Hakko will pay Alnylam $15 million in an upfront cash
payment and up to an additional $78 million in development and sales milestone payments. Upon
commercialization, Alnylam will receive double-digit royalties from Kyowa Hakko based on the sales
of ALN-RSV01 in this territory. The partnership also includes additional RSV-specific RNAi
therapeutic compounds that comprise the ALN-RSV program. Alnylam retains all development and
commercialization rights worldwide excluding Asia.

“We are excited to have formed this new alliance with Kyowa Hakko, a Japanese biotechnology company
with a strong commitment to bringing innovative new drugs to the marketplace,” said John
Maraganore, Ph.D., Chief Executive Officer at Alnylam. “This new collaboration is yet another
example of Alnylam’s commitment to work with leading biotechnology and pharmaceutical companies to
advance RNAi therapeutics to patients on a global basis. This is an important partnership on our
company’s lead clinical program in an important pharmaceutical market and also our third
significant

93

 

alliance formed this year. We will provide an update on our near-term partnership goals and
revised financial guidance at our upcoming second quarter conference call.”

“We have been watching the progress Alnylam has made with their ALN-RSV01 program since last year
and are very excited to partner with this program at this time. We are looking forward to working
with Alnylam, the most scientifically advanced company in the field of RNAi, in the development and
commercialization of ALN-RSV01 in Japan and other major markets in Asia,” said Yuzuru Matsuda,
Ph.D., Chief Executive Officer at Kyowa Hakko. “There is a significant need for novel medicines to
effectively treat patients with RSV, a leading cause of serious infections in both pediatric and
adult patients. We are excited to have the opportunity in delivering the benefit of this novel
medicine to the patients in Asia through the partnership with Alnylam.”

Earlier this year, Alnylam achieved human proof of concept for ALN-RSV01 in the Phase II GEMINI
study, where intranasally administered ALN-RSV01 demonstrated statistically significant anti-viral
efficacy with a 38 percent relative reduction in RSV infection rate and a 95 percent increase in
the number of infection-free subjects as compared with placebo. In addition, Alnylam has initiated
a Phase II clinical trial to assess the safety and tolerability of aerosolized ALN-RSV01 versus
placebo in adult lung transplant patients naturally infected with RSV. As a secondary objective,
this trial will also aim to evaluate the anti-viral activity of ALN-RSV01. The data from this
study, in combination with the previous Phase II GEMINI trial and multiple Phase I trials, will
comprise a comprehensive safety and efficacy data set with which Alnylam expects to further advance
its overall ALN-RSV development program.

About RNA Interference (RNAi )

RNAi (RNA interference) is a revolution in biology, representing a breakthrough in understanding
how genes are turned on and off in cells, and a completely new approach to drug discovery and
development. Its discovery has been heralded as “a major scientific breakthrough that happens once
every decade or so,” and represents one of the most promising and rapidly advancing frontiers in
biology and drug discovery today which was awarded the 2006 Nobel Prize for Physiology or Medicine.
RNAi is a natural process of gene silencing that occurs in organisms ranging from plants to
mammals. By harnessing the natural biological process of RNAi occurring in our cells, the creation
of a major new class of medicines, known as RNAi therapeutics, is on the horizon. RNAi
therapeutics target the cause of diseases by potently silencing specific messenger RNAs (mRNAs),
thereby preventing disease-causing proteins from being made. RNAi therapeutics have the potential
to treat disease and help patients in a fundamentally new way.

About Alnylam Pharmaceuticals

Alnylam is a biopharmaceutical company developing novel therapeutics based on RNA interference, or
RNAi. The company is applying its therapeutic expertise in RNAi to address significant medical
needs, many of which cannot effectively be addressed with small molecules or antibodies, the
current major classes of drugs. Alnylam is leading the translation of RNAi as a new class of
innovative medicines with peer-reviewed research efforts published in the world’s top scientific
journals including Nature, Nature Medicine, and Cell. The company is leveraging these capabilities
to build a broad pipeline of RNAi therapeutics; its most advanced program is in Phase II human
clinical trials for the treatment of respiratory syncytial virus (RSV) infection. In addition, the
company is developing RNAi therapeutics for the treatment of a wide range of disease areas,
including hypercholesterolemia, liver

94

 

cancers, and Huntington’s disease. The company’s leadership position in fundamental patents,
technology, and know-how relating to RNAi has enabled it to form major alliances with leading
companies including Medtronic, Novartis, Biogen Idec, Roche, Takeda, and Kyowa Hakko Kagyo. To
reflect its outlook for key scientific, clinical, and business initiatives, Alnylam has established
“RNAi 2010” which includes the company’s plan to significantly expand the scope of delivery
solutions for RNAi therapeutics, have four or more programs in clinical development, and to form
four or more new major business collaborations, all by the end of 2010. Alnylam is a joint owner
of Regulus Therapeutics LLC, a joint venture focused on the discovery, development, and
commercialization of microRNA therapeutics. Founded in 2002, Alnylam maintains headquarters in
Cambridge, Massachusetts. For more information, visit www.alnylam.com.

          THIS SECOND AMENDMENT AGREEMENT (this “Second Amendment Agreement”) is made as of the
3rd day of June 2010 (the “Second Amendment Effective Date”) by and between:

corporation duly organized and existing under the laws of Japan (hereinafter
referred to as the “Kyowa Hakko”)

          This Second Amendment Agreement amends the License and Collaboration Agreement between Alnylam
and Kyowa Hakko dated June 19, 2008 (the “Agreement”). Capitalized terms used herein and not

          Alnylam and Kyowa Hakko hereby agree to amend the Agreement as follows:

	 	1.	 	Throughout the Agreement, except for Section 1.53 and 3.2, the term “Joint Steering
Committee” will be replaced with the term “Joint Development Committee” and the term “JSC”
will be replaced by the term “JDC”.
	 
	 	2.	 	Section 1.53 of the Agreement is deleted in its entirety
and replaced with the following : “Joint Steering Committee” or “JSC” means the joint steering committee as
more fully described in Section 3.1.5.
	 
	 	3.	 	The first sentence of Section 3.1.1 shall be deleted and replaced by the following
sentence: The Collaboration shall establish a subcommittee of the JSC, called the Joint
Development Committee (the “JDC”) comprised of no less than [**] named representatives of
Kyowa Hakko and no less than [**] named representatives of Alnylam.
	 
	 	4.	 	The last sentence of Section 3.1.3 shall be deleted and replaced by the following
sentences: “Alternatively, the JDC may meet by means of teleconference, videoconference or
other similar communications equipment [**] per Calendar Quarter, but at least [**]
meetings per year shall be conducted in person. Alnylam and Kyowa Hakko have agreed that
representatives of Cubist may be invited as observers to meetings of the JDC, provided,
however, that such representatives of Cubist shall have no voting or decision making
authority in the JDC.”
	 
	 	5.	 	A new Section 3.1.5 would be added containing the following language:

of no less than [**] named representatives of Kyowa Hakko and no less than [**] named

familiarity with the Collaboration. Additional representatives or consultants may
from time to time, by mutual consent of the Parties, be invited to attend JSC

representative of Alnylam. The JSC Chairperson’s responsibilities shall include (a)
scheduling [**] meeting per year, to take place in person; (b) setting agenda for the
meeting with solicited input from other members; (c) confirming and delivering minutes
to the JSC for review and final approval; and (d) conducting effective meetings,
including ensuring that objectives for each meeting are set and achieved.
