 Sales between Astellas and its Affiliates and sublicensees shall be disregarded for purposes of
calculating Net Sales except if such purchaser is a distributor, pharmacy or end user. 
 If a Collaboration Product either (i) is sold
in the form of a combination product containing both a Compound and one or more Active Ingredient(s) as separate molecular entity(ies) that are not Compounds; or (ii) is sold in a form that contains (or is sold bundled with) a delivery device
therefor (in either case ((i) or (ii)), a “Combination Product”), the Net Sales of such Collaboration Product for the purpose of calculating royalties and sales-based milestones owed under this Agreement for sales of such
Collaboration Product, shall be determined as follows: first, Astellas shall determine the actual Net Sales of such Combination Product (using the above provisions) and then such amount shall be multiplied by the fraction A/(A+B), where A is the
invoice price of such Collaboration Product, if sold separately, and B is the total invoice price of other Active Ingredient or delivery device in such Combination Product if sold separately. If any other Active Ingredient or delivery device in such
Combination Product is not sold separately, Net Sales shall be calculated by multiplying actual Net Sales of such Combination Product by a fraction A/C where A is the invoice price of such Collaboration Product if sold separately, and C is the
invoice price of such Combination Product. If neither such Collaboration Product nor any other Active Ingredient (or delivery device) in such Combination Product is sold separately, the adjustment to Net Sales shall be determined by the Parties in
good faith to reasonably reflect the fair market value of the contribution of such Collaboration Product in such Combination Product to the total fair market value of such Combination Product. 

With respect to any sale of any Collaboration Product in a given country for any substantive consideration other than monetary consideration
on arm’s length terms (which has the effect of reducing the invoiced amount below what it would have been in the absence of such non-monetary consideration), for purposes of calculating the Net Sales, such Collaboration Product shall be deemed
to be sold exclusively for cash at the average Net Sales price charged to Third Parties for cash sales of such Collaboration Product in such country during the applicable reporting period (or if there were only de minimis cash sales in such
country, at the fair market value as determined in good faith based on pricing in comparable markets). Notwithstanding the foregoing, Net Sales shall not include amounts (whether actually existing or deemed to exist for purposes of calculation) for
Collaboration Products distributed for use in clinical trials. 
 Net Sales shall be calculated on an accrual basis, in a manner consistent
with Astellas’ accounting policies for external reporting purposes, as consistently applied, in accordance with IFRS. To the extent any accrued amounts used in the calculation of Net Sales are estimates, such estimates shall be trued-up in
accordance with Astellas’ accounting policies for external reporting purposes, as consistently applied, and Net Sales and related payments under this Agreement shall be reconciled as appropriate.

(d) Basis for Royalty. This Section 11.7 is intended to provide for payments to Cytokinetics equal to the percentages of Net Sales
set forth in this Section 11.7 for the duration of the Royalty Term. In establishing this payment structure, the Parties recognize, and Astellas acknowledges, the substantial value of the various actions and investments undertaken by
Cytokinetics prior to the Effective Date and that Cytokinetics will undertake under this Agreement, and that the value of the Cytokinetics Technology licensed to Astellas hereunder resides substantially in Cytokinetics Know-How. As a result, the
Parties attribute such value to Cytokinetics’ leading proprietary knowledge in the subject matter, including trade secrets, preclinical and clinical data pertaining to the Compounds and Collaboration Products, and regulatory filings made by
Cytokinetics prior to the Effective Date, in each case created or generated by Cytokinetics through the expenditure of significant resources and as a result of Cytokinetics’ unique innovative capabilities. The Parties agree that because
Cytokinetics is not separately compensated under this Agreement for such additional benefits, the royalties set forth above are appropriate for the duration of the Royalty Term. The Parties have agreed to the payment structure set forth herein as a
convenient and fair mechanism for both Parties in order to compensate Cytokinetics for these additional benefits as part of the overall consideration for Cytokinetics to enter into this Agreement. 

(e) Royalty Reports and Payment. Within [*] days after each calendar quarter, commencing with the calendar quarter during which the
First Commercial Sale of the first Collaboration Product is made anywhere in the world, Astellas shall provide Cytokinetics with a report that contains the following information for the applicable calendar quarter, on a Collaboration
Product-by-Collaboration Product and country-by-country basis: (i) the amount of gross sales of the Collaboration Products, (ii) an itemized calculation of Net Sales showing deductions provided for in the definition of “Net
Sales”, (iii) a calculation of the royalty payment due on such sales, including [*] in accordance with Section [*] and (iv) the exchange rate for such country. Within [*] days after each calendar quarter, Astellas shall pay in Dollars
all royalties due to Cytokinetics with respect to Net Sales by Astellas, its Affiliates and their respective sublicensees for such calendar quarter.

be able to utilize as a tax credit any amounts withheld or deducted by such paying Party, such other Party shall immediately so notify and, upon such notice, with respect to the amount in
question, such paying Party will be released from the obligation to increase the amount pursuant to this Section 11.11. Such other Party shall provide such paying Party any tax forms that may be reasonably necessary in order for such paying
Party to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty, to the extent legally able to do so. Such other Party shall use reasonable efforts to provide any such tax forms to such paying Party in
advance of the due date. Each Party shall provide the other with reasonable assistance (i) to enable the recovery, as permitted by Law, of withholding taxes or similar obligations resulting from payments made under this Agreement and
(ii) in connection with any audit by any tax authority relating to this Agreement. In the event the paying Party increased the amount of its payment to the other Party to account for any withholding tax, and such other Party later utilizes any
such amount withheld by such paying Party to achieve any tax saving for the benefit of such other Party in the form of a tax deduction, such other Party shall notify such paying Party in writing of the amount of such tax saving and such paying Party
shall have the right to credit such amount of tax saving against its future payment obligations to such other Party. 
 11.12 Records and
Audit Rights. Each Party shall maintain complete and accurate records in sufficient detail to permit the other Party to confirm the accuracy of the amount of Research Plan Costs, Development Costs, [*] to be reimbursed, achievement of sales
milestones, royalty payments and other amounts payable under this Agreement. Upon reasonable prior notice, such records shall be open during regular business hours for a period of [*] years from the creation of individual records for examination by
an independent certified public accountant selected by the auditing Party and reasonably acceptable to the audited Party for the sole purpose of verifying for the auditing Party the accuracy of the financial reports furnished by the audited Party
pursuant to this Agreement or of any payments made, or required to be made, by or to the audited Party pursuant to this Agreement. Such audits not occur more often than once each calendar year. Such auditor shall not disclose the audited
Party’s Confidential Information to the auditing Party, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by the audited Party or the amount of payments to or by the audited Party under
this Agreement. Any amounts shown to be owed but unpaid shall be paid within [*] days after the accountant’s report, plus interest (as set forth in Section 11.10) from the original due date. The auditing Party shall bear the full costs of
such audit unless such audit reveals an overpayment to, or an underpayment by, the audited Party that resulted from a discrepancy in the financial report provided by the audited Party for the audited period, which underpayment or overpayment was
more than [*] of the amount set forth in such report, in which case the audited Party shall reimburse the auditing Party for the costs for such audit. If any such overpayment exceeds such [*] amount, then the auditing Party will refund such amount
to the audited Party within [*] days after the accountant’s report. On the other hand, if any such overpayment does not exceed such [*] amount, the auditing Party shall have the right to credit the amount of such overpayment against its future
payment obligations to the audited Party, provided that such future payments are expected.

 CYTOKINETICS AND ASTELLAS ANNOUNCE EXPANSION OF COLLABORATION 

FOR DEVELOPMENT OF CK-2127107 IN SPINAL MUSCULAR ATROPHY 

AND OTHER NEUROMUSCULAR INDICATIONS 

Cytokinetics Expects to Receive Over $75 Million in Committed Capital and Reimbursements For Planned Activities 

Companies Plan to Initiate Phase II Clinical Trial in 2015 

South San Francisco, CA, and Tokyo, December 23, 2014 – Cytokinetics, Incorporated (NASDAQ:CYTK) and Astellas Pharma Inc.
(Tokyo Stock Exchange: 4503, “Astellas”) announced today an amendment to their collaboration agreement focused on the research, development and commercialization of skeletal muscle activators. The companies have been jointly conducting
research and development activities with the objective to advance novel skeletal sarcomere targeted therapies for diseases and medical conditions associated with muscle weakness in non-neuromuscular indications. The collaboration has been expanded
to enable development of CK-2127107, a fast skeletal troponin activator, in Spinal Muscular Atrophy (SMA) and potentially other neuromuscular indications. As the companies have agreed, Cytokinetics will conduct a Phase II clinical trial of
CK-2127107 in patients with SMA, which is planned to begin in 2015. Cytokinetics and Astellas will jointly develop and may jointly commercialize CK-2127107 and other fast skeletal troponin activators in neuromuscular indications. The companies have
extended their joint research program focused on the discovery of additional skeletal sarcomere activators through 2016. 
 Upon execution of the amended
agreement, Cytokinetics will receive $55 million from Astellas comprising $30 million as an upfront license fee, $10 million paid for Astellas’ purchase of Cytokinetics’ common stock and $15 million in a milestone payment in connection
with the decision made by Astellas to advance CK-2127107 into Phase II clinical development. In addition, Cytokinetics expects to receive potentially over $20 million payable by Astellas to reimburse Cytokinetics for planned research and development
expenses over the next 2 years. Under the amended agreement, Cytokinetics is eligible to receive over $600 million in pre-commercialization and commercialization milestone payments, of which over $100 million is payable for CK-2127107 in each of SMA
and other neuromuscular indications. The agreed terms also provide for escalating royalties to Cytokinetics with increased sales. Cytokinetics retains the option to co-fund the development of CK-2127107 in SMA and other neuromuscular indications in
exchange for increased milestone payments and royalties and, if Cytokinetics exercises its co-promotion option, Astellas will reimburse Cytokinetics for certain expenses associated with its promotion activities. 

“We are pleased to expand our collaboration with Astellas to enable the joint pursuit of CK-2127107 in SMA and other potential neuromuscular indications
as well as the indications which were the initial focus of our collaboration,” stated Robert I. Blum, Cytokinetics’ President and Chief Executive Officer. “We are impressed with Astellas’ strategic vision for skeletal muscle
activators and look forward to increasing the scope of our activities to prioritize the treatment of neuromuscular diseases that may benefit from our novel mechanism approach to increased muscle function and time to muscle fatigue.” 

“We are excited to expand our collaboration with Cytokinetics and to advance this drug candidate into Phase II,” stated Yoshihiko Hatanaka,
Astellas’ President and Chief Executive Officer. “We are encouraged by the result of the completed Phase I studies for CK-2127107 and are hopeful for the future of this new frontier of muscle biology. The expansion of our alliance is a
testament to our productive collaboration together and illustrates the broad potential that we envision for this program.” 
 Expanded Scope of
Collaboration 
 Cytokinetics and Astellas entered into collaboration in 2013. Cytokinetics exclusively licensed to Astellas the rights to co-develop and
commercialize CK-2127107, a fast skeletal troponin activator drug candidate, for potential application in non-neuromuscular indications under the collaboration agreement. In accordance with the initial scope of the collaboration, Cytokinetics
completed Phase I clinical development activities and other Phase II readiness activities. In connection with the 








 Cytokinetics’ and Astellas’ Announcement Regarding Expansion of Skeletal Muscle Activator
Collaboration 
 Page 2 
  

 
expanded collaboration, the companies have agreed to advance CK-2127107 into Phase II clinical development initially in SMA. The development program may include other neuromuscular indications as
the companies may agree in the future. In connection with the expanded collaboration, Cytokinetics and Astellas have also agreed to extend their joint research program through 2016. Under the amended collaboration, Astellas has exclusive rights to
co-develop and commercialize CK-2127107 and other fast skeletal troponin activators in non-neuromuscular indications and certain neuromuscular indications (including SMA) and other novel mechanism skeletal muscle activators in all indications,
subject to certain Cytokinetics’ development and commercialization rights; Cytokinetics may co-promote and conduct certain commercial activities in North America and Europe under agreed scenarios. Outside the collaboration, Cytokinetics may
continue to independently develop tirasemtiv, a fast skeletal troponin activator that recently completed a Phase II clinical trials program for the potential treatment of amyotrophic lateral sclerosis (ALS), in ALS and other neuromuscular
indications subject to certain agreed limitations.

 About CK-2127107 

Skeletal muscle contractility is driven by the sarcomere, the fundamental unit of skeletal muscle contraction. It is a highly ordered cytoskeletal structure
composed of several key proteins. Skeletal muscle myosin is the cytoskeletal motor protein that converts chemical energy into mechanical force through its interaction with actin. A set of regulatory proteins, which includes tropomyosin and several
types of troponin, make the actin-myosin interaction dependent on changes in intracellular calcium levels. CK-2127107, a novel skeletal muscle activator arising from Cytokinetics’ skeletal muscle contractility program, slows the rate of calcium
release from the regulatory troponin complex of fast skeletal muscle fibers, which sensitizes the sarcomere to calcium, leading to an increase in skeletal muscle contractility. CK-2127107 has demonstrated pharmacological activity that may lead to
new therapeutic options for diseases associated with muscle weakness and fatigue. In non-clinical models of Spinal Muscular Atrophy, a skeletal muscle activator has demonstrated increases in skeletal submaximal muscle force in response to neuronal
input and delays in the onset and reductions in the degree of muscle fatigue. CK-2127107 has been the subject of five completed Phase I clinical trials in healthy volunteers, which evaluated safety, tolerability, bioavailability, pharmacokinetics
and pharmacodynamics. 
 About Spinal Muscular Atrophy 

Spinal Muscular Atrophy (SMA) is a severe neuromuscular disease that occurs in 1 in every 6,000 to 10,000 live births each year and is one of the most common
fatal genetic disorders. Spinal muscular atrophy manifests in various degrees of severity as progressive muscle weakness resulting in respiratory and mobility impairment. There are four types of SMA, named for time of the initial onset of muscle
weakness and related symptoms: Type I (Infantile), Type II (Intermediate), Type III (Juvenile) and Type IV (Adult onset). Life expectancy and disease severity varies by type of SMA from Type I, who have the worst prognosis and a life expectancy of
no more than 2 years from birth, to the Type IV, who have a normal life span but with gradual weakness in the proximal muscles of the extremities resulting in mobility issues. Few treatment options exist for these patients, resulting in a high unmet
need for new therapeutic options to address symptoms and modify disease progression. 
 About Cytokinetics 

Cytokinetics is a clinical-stage biopharmaceutical company focused on the discovery and development of novel small molecule therapeutics that modulate muscle
function for the potential treatment of serious diseases and other medical conditions. Cytokinetics currently has three compounds in clinical development: omecamtiv mecarbil in Phase II for acute and chronic heart failure, tirasemtiv
in Phase II for ALS and CK-2127107 progressing to Phase II in SMA. All of the company’s drug candidates have arisen from Cytokinetics’ muscle biology focused research activities and are directed towards the cytoskeleton. The cytoskeleton
is a complex biological infrastructure that plays a fundamental role within every human cell. Additional information about Cytokinetics can be obtained at http://www.cytokinetics.com.
