(a)[ * ];

(b)[ * ];

(c)[ * ];

(d)[ * ]; and

(e)[ * ].

If a single item falls into more than one of the categories set forth in clauses (a)-(e) above, such item may not be deducted more than once.

Sales among Cytokinetics, its Affiliates, licensees, and sublicensees shall be disregarded for purposes of calculating Net Sales except if such purchaser is a distributor, pharmacy or end user. Net Sales also exclude any sale or transfer of any FSRA Product in early access or named patient programs.

If a Reldesemtiv Product either (i) is sold in the form of a combination product containing both the applicable FSRA and one or more Active Ingredient(s) as separate molecular entity(ies) that are not such FSRA; 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 Reldesemtiv Product”), the Net Sales of such Reldesemtiv Product for the purpose of calculating royalties owed under this Agreement for sales of such Reldesemtiv Product, shall be determined as follows: first, the actual Net Sales of such Combination Reldesemtiv Product shall be determined by Cytokinetics using the above provisions, and then such amount shall be multiplied by the fraction A/(A+B), where A is the invoice price of the Reldesemtiv Product that contains only such FSRA, if sold separately, and B is the total invoice price of other Active Ingredient or delivery device in such Combination Reldesemtiv Product if sold separately. If any other Active Ingredient or delivery device in such Combination Reldesemtiv Product is not sold separately, Net Sales shall be calculated by multiplying actual Net Sales of such Combination Reldesemtiv Product by a fraction A/C where A is the invoice price of the Reldesemtiv Product that contains only such FSRA if sold separately, and C is the invoice price of such Combination Reldesemtiv Product. If neither such Reldesemtiv Product that contains only such FSRA nor any other Active Ingredient (or delivery device) in such Combination Reldesemtiv 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 the applicable FSRA in such Combination Reldesemtiv Product to the total fair market value of such Combination Reldesemtiv Product.

With respect to any sale of any Reldesemtiv 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 Reldesemtiv 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 Reldesemtiv 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 Reldesemtiv Product distributed for use in clinical trials.

Net Sales shall be calculated on an accrual basis, in a manner consistent with Cytokinetics’ accounting policies for external reporting purposes, as consistently applied, in accordance with GAAP. To the extent any accrued amounts used in the calculation of Net Sales are estimates, such estimates shall be trued-up in accordance with Cytokinetics’ accounting policies for external reporting purposes, as consistently applied, and Net Sales and related payments under this Agreement shall be reconciled as appropriate.

1.45“Patent Rights” means all patents and patent applications (which shall be deemed to include certificates of invention and applications for certificates of invention), including all divisionals, continuations, substitutions, continuations-in-part, re-examinations, reissues,

Within [ * ] days after the end of each calendar quarter in which Cytokinetics has incurred any Shared Development Cost for CY 5031, Cytokinetics shall submit to Astellas a reasonably detailed reconciliation report setting forth the accounting for, and an invoice for thirty-three percent (33%) of, the actual Shared Development Cost for CY 5031incurred by or on account of Cytokinetics in such calendar quarter and any credits or deficits from the corresponding Shared Development Advance Invoice previously provided for such quarter (the “Shared Development True Up Report”). If the estimated Shared Development Cost paid by Astellas pursuant to Section 5.1(b)(i) above for such calendar quarter is less than thirty-three percent (33%) of Cytokinetics’ actual Shared Development Cost for such quarter, then Astellas shall pay the deficit to Cytokinetics as described in this Section 5.1(b)(ii). If the estimated Shared Development Cost paid by Astellas pursuant to Section 5.1(b)(i) above for such prior calendar quarter is more than thirty-three percent (33%) of Cytokinetics’ actual Shared Development Cost for such calendar quarter, the excess shall be credited toward the Shared Development Advance Invoice for the next calendar quarter (except where such invoice is the final such invoice to be provided by Cytokinetics, in which case the excess shall be refunded by Cytokinetics to Astellas within [ * ] days after the delivery of such invoice).

(iii)Timing of Payment. For ease of administration, Astellas shall pay Cytokinetics a single payment reflecting the amount due under the Shared Development Advance Invoice for the current calendar quarter plus any deficits (or less any credits) reflected in the Shared Development True Up Report for the prior calendar quarter within the later of (i) [ * ] days of Astellas’ receipt of such Shared Development Advance Invoice, or (ii) [ * ] days of Astellas’ receipt of such Shared Development True Up Report.

(c)Cap on Astellas’ Obligation. Astellas’ obligation to share the Shared Development Cost shall cease once the total amount paid by Astellas under this Section 5.1 reaches twelve million Dollars ($12,000,000). Cytokinetics shall be solely responsible for the cost of CY 5031 after such cap has been reached (if any).

5.2Royalty Payment from Cytokinetics to Astellas.

(a)Royalty Rate.

(b)Tax Cooperation. The Parties agree to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of royalties and other payments made by a Party to the other Party under this Agreement. To the extent such paying Party is required to deduct and withhold taxes on any payment to the other Party, such paying Party shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner, and the sum payable to such other Party shall be increased to the extent necessary to ensure that such other Party receives a sum equal to the sum which it would have received had there been no such withholding tax. Notwithstanding the foregoing, if the paying Party is obliged to pay withholding taxes and the other Party reasonably foresees that it will 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 5.6. 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.

Such audits shall not occur more often than once each calendar year. Such auditor shall not disclose Cytokinetics’ Confidential Information to Astellas, except to the extent such disclosure is necessary to verify the accuracy of the financial reports furnished by Cytokinetics or the amount of payments 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 5.5) from the original due date. Astellas shall bear the full costs of such audit unless such audit reveals an overpayment to, or an underpayment by, Cytokinetics that resulted from a

discrepancy in the financial report provided by Cytokinetics for the audited period, which underpayment or overpayment was more than [ * ] of the amount set forth in such report, in which case Cytokinetics shall reimburse Astellas for the costs for such audit. If any such overpayment exceeds such [ * ] amount, then Astellas shall refund such amount to Cytokinetics within [ * ] days after the accountant’s report. On the other hand, if any such overpayment does not exceed such [ * ] amount, Astellas shall have the right to credit the amount of such overpayment against its future payment obligations to Cytokinetics, provided that such future payments are expected.
