All deductions in clauses (a) through (g) above will be fairly and equitably allocated between such Collaboration Product and other products of CStone and its Affiliates and Sublicensees such that such Collaboration Product does not bear a disproportionate portion of such deductions.  Calculations of Net Sales will be consistently applied across all products of Seller and will be consistent between periods.

Transfers or sales between CStone and its Affiliates and Sublicensees will be disregarded for purposes of calculating Net Sales, except if such purchaser is an end user.

In the event of any sale of a Blueprint/CStone Combination that is not an Amalgamated Product (i.e., both the Blueprint Product and the CStone Product that comprise the Blueprint/CStone Combination are available for sale separately, each as a monotherapy), the Net Sales from such Blueprint/CStone Combination for the purposes of determining payments hereunder based on Net Sales of such Blueprint/CStone Combination will be the sales of the applicable Blueprint Product during the applicable reporting period.

If a Collaboration Product is sold as part of an Amalgamated Product (including any Blueprint/CStone Combination or Blueprint Combination Product), then the Net Sales of the Collaboration Product will be calculated for each applicable reporting period by multiplying the Net Sales (as determined without reference to this paragraph) of the Amalgamated Product by the fraction, A/(A+B), where A is the average gross selling price in the applicable region of the Blueprint Product when sold separately in finished form, and B is the average gross selling price in the applicable region of the Other Components included in the Amalgamated Product when sold separately in finished form, in each case for the most recent period in which sales of both occurred.

If the Collaboration Product is sold as part of an Amalgamated Product and is sold separately in finished form, but the Other Components included in the Amalgamated Product are not sold separately in finished form, then the Net Sales of the Collaboration Product will be determined by multiplying the Net Sales of the Amalgamated Product by the fraction A/C where: A is the average gross selling price in the applicable region of the Collaboration Product contained in such Amalgamated Product when sold separately, and C is the average gross selling price in the applicable region of the Amalgamated Product.  If the Collaboration Product is sold as part of an Amalgamated Product and is not sold separately in finished form, but the Other Components included in the Amalgamated Product are sold separately in finished form, then the Net Sales of the Collaboration Product will be determined by multiplying the Net Sales of the Amalgamated Product by the fraction C-B/C where: B is the average gross selling price of the Other Component included in such Amalgamated Product when sold separately, and C is the average gross selling price of the Amalgamated Product.

If Net Sales of the Collaboration Product when included in an Amalgamated Product cannot be determined using the methods above (as neither the Collaboration Product nor the Other Components are sold separately), then the average gross selling prices in the above described equation in the applicable region in the Territory will be replaced with the Parties’ agreed estimate of the fair market value of the products for which no such sales exist in such region.  At least [***] prior to the First Commercial Sale of any Amalgamated Product in a region in the Territory, CStone will propose such good faith estimate to Blueprint, and Blueprint will [***] consider such proposal, and the Parties will seek to reach agreement on such allocation.  If the Parties are unable to reach such agreement within [***] after CStone provides such proposal, then the issue will be resolved in accordance with Section Article 16 (Dispute Resolution).

3.7         Resolution of JSC Disputes.

3.7.1      Referral to Executive Officers.  If a Party makes an election under Section 3.6.3 (Decisions of the JSC) to refer a matter on which the JSC cannot reach a consensus decision for resolution by the Executive Officers, then the JSC will submit in writing the respective positions of the Parties to their respective Executive Officers.  The Executive Officers will [***] resolve any such matter so referred to them [***], and any final decision that the Executive Officers agree to in writing will be conclusive and binding on the Parties.

3.7.2      Final Decision-Making Authority.  If the Executive Officers are unable to reach agreement on any such matter referred to them [***] after such matter is so referred (or such longer period as the Executive Officers may agree upon), then:

(a)         No Change; Status Quo.  Neither Party will have final decision-making authority (i) over the allocation to CStone of any Development activities set forth in the Global Development Plan to be conducted by CStone outside of the Territory, (ii) over the following Territory-specific Development activities that are to be conducted by CStone under a Global Development Plan in the Territory: selection of Clinical Trial sites, principal investigators, CROs in the Territory, and compliance with any requirements of a Regulatory Authority to the extent necessary to obtain Regulatory Approval in the Territory from such Regulatory Authority, (iii) to require CStone to serve as the Territory Sponsor or regulatory agent of any Global Clinical Trial for a Collaboration Product for a New Indication, (iv) as to whether to conduct further Development of the BLU-554/CStone Checkpoint Combination or the BLU-554/Other Checkpoint Combination as a first line therapy for the HCC Indication under BLU-554 Scenario 1 or BLU-554 Scenario 2, respectively, (v) as to whether to approve any Combination Regimen that includes a Proposed Additional Blueprint/CStone Combination (or any other Combination Regimen that includes the CStone Checkpoint Antibody other than the BLU-554/CStone Checkpoint Combination) as a Blueprint/CStone Combination under this Agreement, (vi) over the Manufacturing Technology Transfer Plan or the scope of Manufacturing activities that will be conducted by CStone, (vii) over the Development of Companion Diagnostics by CStone for use in connection with the Commercialization of any Collaboration Product in the Territory, (viii) over whether to extend the period during which Blueprint will supply to CStone any [***] Blueprint Products beyond [***] for such Blueprint Product, (ix) over any brand strategy for a Collaboration Product that is specific to the Territory (or any region therein) and that is inconsistent with the Global Brand Strategy for such Collaboration Product, (x) over any changes to then-current FTE Rates for a Party, (xii) as to whether to approve any Subcontractor as a Preapproved Subcontractor for purposes of this Agreement, or (xii) the CStone New Indication Share with respect to a New Indication for a Collaboration Product, and all such matters set forth in the foregoing clauses ((i) through (xii)) must be decided by unanimous agreement of the Parties in order to take any action or adopt any change from the then-current status quo.

(b)         CStone Decisions.  CStone will have final decision-making authority with respect to the Manufacture of a Blueprint Product in the Territory [***] for such Blueprint Product (but not with respect to determining the scope of the Manufacturing activities for any Blueprint Product that will be conducted by CStone, which changes in scope must be agreed unanimously).  In addition, if the JSC is unable to reach agreement as to whether to conduct further Development of the BLU-

554/CStone Checkpoint Combination or the BLU-554/Other Checkpoint Combination as a first line therapy for the HCC Indication under BLU-554 Scenario 1 or BLU-554 Scenario 2, respectively, then CStone will have final decision-making authority over whether to conduct, as a Territory-Specific Clinical Trial in the Territory, the Pivotal Trial for the BLU-554/CStone Checkpoint Combination as a first line therapy for the HCC Indication pursuant to BLU-554 Scenario 3, and if CStone elects to conduct such Pivotal Trial as a Territory-Specific Clinical Trial, then CStone will be solely responsible for the conduct of such trial at its cost and expense.  CStone will also have final decision-making authority to create a Product Mark for a Collaboration Product for use in the Territory that deviates from Blueprint’s Global Brand Elements if the JSC is unable to agree as to whether a Product Mark is appropriate for the Territory due to linguistic reasons or market research showing that such Product Mark is not appropriate for use in the Territory. Lastly, CStone will have the final decision-making authority with respect to any Territory-specific activities related to the Development (including regulatory strategy), performance of Medical Affairs, or Commercialization of the Blueprint Compounds and the Collaboration Products in the Territory, including any Territory-Specific Clinical Trials for a Collaboration Product or the initial Territory-Specific Development Plan and updates thereto (but not any Global Brand Strategy or Development activities in the Territory under any Global Development Plan); provided that:

(i)          CStone’s decision is, in each case, consistent with its obligations under this Agreement, including its obligations to use Commercially Reasonable Efforts to Develop and Commercialize the Blueprint Compounds and the Collaboration Products set forth under Section 5.1 (Development Diligence and Responsibilities) and Section 9.1 (Commercialization Diligence Obligations); and

(ii)         CStone will not be permitted to exercise its final decision-making authority to make any decision that would reasonably be expected to: (A) result in a material quality, safety, toxicity, or side effect concern with respect to a Blueprint Compound or Collaboration Product; (B) materially adversely affect the continued Development, performance of Medical Affairs, or Commercialization of the Blueprint Compounds or the Collaboration Products outside of the Territory; (C) be inconsistent with Blueprint’s Global Brand Strategy for any Collaboration Product; or (D) cause Blueprint to be in violation of Applicable Law as the Territory Sponsor or as the owner and holder of Regulatory Submissions, Regulatory Approvals, or any Reimbursement Approvals, as applicable, for the Collaboration Products in the Territory.

(c)         Blueprint Decisions.

(i)          Blueprint will have final decision-making authority with respect to Manufacturing of a Collaboration Product at all times prior to [***] for the applicable Blueprint Product (or the Blueprint Product included in any Combination Regimen, if applicable), and thereafter with respect to the Manufacture of the Active Ingredients in any Blueprint Product [***].

(ii)         If the JSC is unable to reach agreement as to whether to conduct further Development of the Blueprint/CStone Checkpoint Combination or a BLU-554/Other Checkpoint Combination as a first line therapy for the HCC Indication under either BLU-554 Scenario 1 or BLU-554 Scenario 2, respectively, then Blueprint will have final decision-making authority as to whether to conduct, as a Global Clinical Trial, the Pivotal Trial for a BLU-554/Other Checkpoint Combination as a first line therapy for the HCC Indication pursuant to BLU-554 Scenario 3, and if Blueprint elects to conduct such Pivotal Trial as a Global Clinical Trial, then the Parties will be responsible for the costs and expenses of such trial in accordance with Section 5.4.6 (Scenario 3 Election).

(iii)       If the JSC is unable to reach agreement as to whether to conduct the BLU-554/Other Checkpoint Combination POC Trial pursuant to the applicable Global Development Plan or as to which Party will be responsible for conducting such trial, then Blueprint will have the right to exercise final decision-making authority to determine whether to conduct such trial, and if Blueprint determines to conduct such trial, then Blueprint will be responsible for conducting the BLU-554/Other Checkpoint Combination POC Trial.

(iv)        Blueprint will have final decision-making authority with respect to any Development outside of the Territory and Medical Affairs activities outside of the Territory and Blueprint will have final decision-making authority with respect to any Development inside of the Territory that (A), subject to Section 3.7.2(a) (No Change; Status Quo), is included in a Global Development Plan for a Collaboration Product, (B) in Blueprint’s reasonable belief will materially adversely affect a global non-clinical or preclinical study, Clinical Trial, or other Development of a Blueprint Compound, Blueprint Product, or Blueprint Combination Product outside of the Territory, (C) is proposed in any New Development Proposal, or (D) in Blueprint’s reasonable belief may adversely affect Blueprint’s compliance with obligations under Applicable Law as the Territory Sponsor or as the owner and holder of Regulatory Submissions, Regulatory Approvals, Reimbursement Approvals, or other approvals or authorizations applicable to the Exploitation of Collaboration Products in the Territory, as applicable, for one or more Collaboration Products in the Territory.

3.7.3      Limitations on Decision-Making.  Notwithstanding anything to the contrary set forth in this Agreement, without the other Party’s prior written consent, no decision of the JSC or a Party’s Executive Officer (in the exercise of a Party’s final decision‑making authority on any such matters), in each case, may (a) result in a [***] in the other Party’s obligations, costs, or expenses under this Agreement, or any Global Development Plan or Territory-Specific Development Plan (including any budget set forth in a Global Development Plan or a Territory-Specific Development Plan), unless, in each case, such actions are necessary for Blueprint to comply with Applicable Law as the Territory Sponsor or as the owner and holder of any Regulatory Submission, Regulatory Approval, or Reimbursement Approval, as applicable, for a Collaboration Product in the Territory, (b) take or decline to take any action that would [***] result in a violation of any Applicable Law, the requirements of any Regulatory Authority, or any agreement with any Third Party (including any agreement

pursuant to which Blueprint Controls any Blueprint Technology or CStone Controls any CStone Product Technology or CStone General Collaboration Technology) or would [***] result in the infringement or misappropriation of intellectual property rights of any Third Party, (c) impose any obligation on either Party that would be in violation of such Party’s written standard operating procedures, written business policies, or written compliance policies or procedures, or (d) conflict with this Agreement, any Clinical Supply Agreement, any Commercial Supply Agreement, any Safety Agreement, or any other agreement between the Parties related to the subject matter set forth herein.

3.8         Discontinuation of JSC.  The JSC will continue to exist until the first to occur of (a) the Parties agreeing to disband the JSC, or (b) Blueprint providing written notice to CStone of its intention to disband and no longer participate in the JSC.  Once the JSC is disbanded, the JSC will have no further obligations under this Agreement and, thereafter, the Alliance Managers will be the points of contact for the exchange of information between the Parties under this Agreement and any references in this Agreement to decisions of the JSC will automatically become references to decisions by and between the Parties in writing, subject to the other terms of this Agreement and consistent with the terms of Section 3.7.2 (Final Decision-Making Authority).

Article 6

REGULATORY

6.1         Regulatory Strategy; Combination Regimens Including BLU-554.  The JPT will discuss and develop a regulatory strategy for each Collaboration Product and will submit the same to the JSC to review, discuss, and determine whether to approve.  Without limiting the generality of the foregoing, the JPT will discuss and develop, and submit the same to the JSC to review, discuss, and determine whether to approve, a regulatory strategy for receipt of approval from the CNDA with respect to the conduct of (a) the BLU-554/CStone Checkpoint Combination POC Trial [***], and (b) if the JSC approves the conduct thereof, the BLU-554/Other Checkpoint Combination POC Trial, [***].  In addition, if the JSC approves the further Development of the BLU-554/CStone Checkpoint Combination or the BLU-554/Other Checkpoint Combination beyond the applicable BLU-554 Combination POC Trials (including any BLU-554 Combination Pivotal Trial), then the JPT will discuss any changes to the applicable JSC-approved regulatory strategy required for such

further Development and submit the same to the JSC to review, discuss, and determine whether to approve.  From time to time the JPT may update the regulatory strategy for any Collaboration Product and submit the same to the JSC to review, discuss, and determine whether to approve.  Once approved by the JSC, each update to a regulatory strategy for such a Collaboration Product will become effective and supersede the then-current regulatory strategy for such Collaboration Product.

6.2         CStone’s Responsibilities.

6.2.1      Obtaining and Maintaining Regulatory Approvals.  Each Party will keep the other Party informed of regulatory developments related to the Collaboration Products in each region in the Territory and will promptly notify the other Party in writing of any decision by any Regulatory Authority in the Territory regarding any Collaboration Product.

(a)         In the PRC. Prior to [***] CStone or one of its Affiliates will be responsible for undertaking all regulatory activities and interactions with Regulatory Authorities in the PRC for such Blueprint Product (and any Combination Regimen of which such Blueprint Product is a part) in Blueprint’s name as the express and authorized regulatory agent of record for Blueprint in the Territory and will take such actions on behalf of and for the benefit of Blueprint in the PRC in accordance with the applicable regulatory strategy approved by the JSC (including performing any and all regulatory activities assigned to CStone in this Agreement or by the JSC during the Term in connection with the Development or Commercialization of a Collaboration Product in the Territory). Following (i) [***] and (ii) [***], CStone or one of its Affiliates will be responsible for all regulatory activities and interactions with Regulatory Authorities in the PRC leading up to and including obtaining (to the extent not already obtained) and thereafter maintaining, Local Manufacturing Approvals, Regulatory Approvals, and any Reimbursement Approvals, as applicable, for such locally-Manufactured Blueprint Product (and any Combination Regimen of which such locally-Manufactured Blueprint Product is a part) in the PRC in CStone’s or its Affiliate’s own name in accordance with the applicable regulatory strategy approved by the JSC.  Prior to undertaking any such activities and interactions relating to obtaining and maintaining Local Manufacturing Approvals, Regulatory Approvals, or Reimbursement Approvals for any Collaboration Product in the PRC, whether prior to or after [***] for the applicable Blueprint Product, CStone will submit a reasonably detailed plan for undertaking the same to the JSC for review and discussion.  Following [***] for a Blueprint Product, CStone or one of its Affiliates will continue to be responsible for all regulatory activities and interactions with Regulatory Authorities in the PRC with respect to any imported version of such Blueprint Product (and any Combination Regimen of which such imported Blueprint Product is a part) as the express and authorized regulatory agent of record for Blueprint in the PRC and will continue to take such actions with respect to the imported Blueprint Product on behalf of and for the benefit of Blueprint in the PRC in accordance with the applicable regulatory strategy approved by the JSC. For clarity, if [***] does not occur for a Blueprint Product because the applicable Manufacturing Technology Transfer Plan approved by the JSC for such Blueprint Product does not contemplate the transfer of Manufacturing activities to CStone sufficient for CStone to obtain all applicable Regulatory Approvals required to market and sell a locally-Manufactured version of such Blueprint Product in the PRC in the name of CStone or its Affiliate, then CStone or one of its Affiliates will continue to act

as Blueprint’s regulatory agent of record in the Territory with respect to such Blueprint Product (and any Combination Regimen of which such Blueprint Product is a part), in each case, as set forth in this Section 6.2.1 (Obtaining and Maintaining Regulatory Approvals), and neither CStone nor any of its Affiliates will be obligated to obtain Regulatory Approval for such Blueprint Product in the PRC in the name of CStone or any of its Affiliates.

(b)         Obtaining and Maintaining Regulatory Approvals outside the PRC. CStone will be responsible for all regulatory activities leading up to and including obtaining, and thereafter maintaining, Regulatory Approvals and any Reimbursement Approvals in all regions of the Territory other than the PRC in its own name or in the name of its Affiliate, Sublicensee, or Third Party Distributor.

6.2.2      Consultation with CNDA. Following receipt of the IND for each Collaboration Product, if the Parties determine to pursue any Development of the applicable Collaboration Product that is not included in the scope of the protocols submitted with the initial IND (e.g., to add the performance of Clinical Trials for any Combination Regimen), then at Blueprint’s reasonable request CStone will request a consultation meeting with the CNDA to discuss such additional Development in advance of implementing such additional or revised Clinical Trial protocols.

6.2.3      Review of Regulatory Submissions.  CStone will provide to Blueprint for review and comment drafts of all Regulatory Submissions in the Territory for the Collaboration Products, other than the pre-IND meeting request referred to in Section 5.1.4(a) (BLU-554 Monotherapy Clinical Trials).  CStone will incorporate any comments received from Blueprint on such Regulatory Submissions where required under Applicable Law and will consider [***] and incorporate [***] any other comments received from Blueprint on such Regulatory Submissions.  In addition, each Party will notify the other Party of any Regulatory Submissions for the Collaboration Products and any comments or other correspondences related thereto submitted to or received from any Regulatory Authority in the Territory and will provide the other Party with copies thereof as soon as reasonably practicable, but in all events within [***] after submission or receipt thereof (or such longer time period as may be necessary to obtain translations thereof).  If any such Regulatory Submission, comment, or correspondence is not in English, then CStone will also provide Blueprint with a certified English translation as soon as practicable after receipt of such Regulatory Submission, comment, or correspondence[***].  Blueprint will have the right to review and comment on all such Regulatory Submissions, and CStone will [***] and incorporate such comments [***].

6.2.4      Notice of Meetings.  Each Party will provide the other Party with notice of any meeting or discussion with any Regulatory Authority in the Territory related to any Collaboration Product no later than [***] after receiving notice thereof [***].  CStone will lead any such meeting or discussion and Blueprint or its designee will have the right, but not the obligation, to attend and participate in any such meeting or discussion unless prohibited or restricted by Applicable Law or Regulatory Authority, provided that to the extent such meeting or discussion relates solely to any locally-Manufactured version of Blueprint Products after [***] for such Blueprint Product, Blueprint or its designee will have the right to [***] such meeting or discussion.  At CStone’s request, Blueprint will reasonably cooperate with CStone in preparing for any such meeting or discussion.  If Blueprint elects not to attend such meeting or discussion, then CStone will provide to Blueprint a written summary thereof in English promptly following such meeting or discussion.  For clarity,

the terms of this Section 6.2.4 (Notice of Meetings) do not apply to any meeting or discussion relating solely to any CStone Product.

10.12.4 Returns.  All transfer, documentary, sales, use, stamp, registration, and other such Taxes, and any conveyance fees, recording charges, and other fees and charges (including any penalties and interest) incurred in connection with consummation of the transactions contemplated hereby, if any, will be borne and paid by the Paying Party.  The Paying Party will prepare and timely file all tax returns required to be filed in respect of any such Taxes.  The Parties will reasonably cooperate in accordance with Applicable Law to minimize transfer Taxes in connection with this Agreement.

the Prosecuting Party, assume the Patent Prosecution of such Patent Right in the applicable territory.  In such event, (i) the other Party will become the Prosecuting Party with respect to such Joint Collaboration Patent Rights in the applicable territory, (ii) the other Party will be continue to be responsible for [***] of the out-of-pocket costs incurred by the Prosecuting Party as set forth under Section 14.3.3(a) (Blueprint/CStone Combination Technology), and (iii) the other Party (that is no longer the Prosecuting Party) will retain the rights to review and consult set forth in Section 14.3.3(b) (Review and Consult).

14.3.4    Cooperation.  Each Party will provide the other Party all reasonable assistance and cooperation in the Patent Prosecution efforts under this Section 14.3 (Patent Prosecution), including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution.

14.4       Patent Enforcement.

14.4.1    Notice.  Each Party will notify the other within [***] of becoming aware of any alleged or threatened infringement by a Third Party of any of the (a) Blueprint Patent Rights in the Territory, (b) CStone General Collaboration Patent Rights in the Territory, or (c) Blueprint/CStone Combination Patent Rights or other Joint Collaboration Patent Rights in the Territory, and, in each case, any related declaratory judgment or equivalent action alleging the invalidity, unenforceability, or non-infringement of such Patent Rights (collectively “Product Infringement”).  Each Party will also notify the other within [***] of becoming aware of any alleged or threatened infringement by a Third Party of any CStone General Collaboration Patent Right that adversely affects or is expected to adversely affect any Collaboration Product outside of the Territory, including any related declaratory judgment or equivalent action alleging the invalidity, unenforceability or non-infringement of any such Patent Rights (an “Ex-Territory Infringement”).  For clarity, Product Infringement and Ex-Territory Infringement each exclude any adversarial Patent Prosecution proceedings.

14.4.2    Enforcement Rights.

(a)         First Right; Step-In.

(i)          Blueprint First Right.  Blueprint will have the first right to bring and control any legal action to enforce Blueprint Patent Rights and Joint Collaboration Patent Rights other than the Blueprint/CStone Combination Patent Rights against any Product Infringement in the Territory as it reasonably determines appropriate, and Blueprint will consider [***] the interests of CStone in such enforcement of the Blueprint Patent Rights and such Joint Collaboration Patent Rights.

(ii)         CStone First Right.  CStone will have the first right to bring and control any legal action to enforce the Blueprint/CStone Combination Patent Rights against any Product Infringement in the Territory as it reasonably determines appropriate, and CStone will consider [***] the interests of Blueprint in such enforcement of the Blueprint/CStone Combination Patent Rights.  The Party with the first right to bring and control any legal action to enforce the Blueprint Patent Rights, Blueprint/CStone

Combination Patent Rights, or other Joint Collaboration Patent Rights, as applicable, will be referred to herein as the “Controlling Party.”

(iii)       Step-In Rights.  If the Controlling Party or its designee fails to abate such Product Infringement in the Territory or to file an action to abate such Product Infringement in the Territory within [***] after a written request from the other Party to do so, or if the Controlling Party discontinues the prosecution of any such action after filing without abating such infringement, then, in either case, the other Party will have the right to enforce the applicable Patent Rights against such Product Infringement in the Territory as it reasonably determines appropriate provided that (A) the Controlling Party does not provide reasonable rationale for not doing so or continuing to do so (including a substantive concern regarding counter-claims by the infringing Third Party), and (B) the other Party will not enter into any settlement admitting the invalidity of, or otherwise impairing, of any such Patent Rights without the prior written consent of the Controlling Party.

(iv)        CStone’s Patent Rights.  CStone will have the sole right to bring and control any legal action to enforce CStone General Collaboration Patent Rights and CStone Product Patent Rights against any Product Infringement in the Territory at its own expense as it reasonably determines appropriate.  CStone will not have the right to enforce any Blueprint Patent Rights, Blueprint/CStone Combination Patent Rights, or other Joint Collaboration Patent Rights outside of the Territory.  Notwithstanding the foregoing, CStone will have the sole right and authority to enforce Patent Rights Controlled by CStone or its Affiliates that Cover a CStone Product (other than a Blueprint/CStone Combination) inside and outside of the Territory.

(b)         Control of Ex-Territory Infringements.  CStone will have the first right to bring and control any legal action that it reasonably determines appropriate to enforce any CStone General Collaboration Patent Rights against any Ex-Territory Infringement outside of the Territory at its own expense, and CStone will consider [***] the interests of Blueprint in such enforcement of the CStone General Collaboration Patent Rights.  If CStone or its designee fails to abate such Ex-Territory Infringement outside of the Territory or to file an action to abate such Ex-Territory Infringement outside of the Territory within [***] after a written request from Blueprint to do so, or if CStone discontinues the prosecution of any such action after filing without abating such infringement, then, in either case, Blueprint will have the right to enforce such CStone General Collaboration Patent Rights against such Ex-Territory Infringement outside of the Territory as it reasonably determines appropriate provided that (i) CStone does not provide reasonable rationale for not doing so or continuing to do so (including a substantive concern regarding counter-claims by the infringing Third Party), and (ii) Blueprint will not enter into any settlement admitting the invalidity of, or otherwise impairing, any CStone General Collaboration Patent Rights without the prior written consent of CStone.

14.4.3    Cooperation.  At the request of the Party bringing an action related to a Product Infringement or Ex-Territory Infringement, the other Party will provide reasonable

assistance in connection therewith, including by executing reasonably appropriate documents, cooperating in discovery, and joining as a party to the action if required by Applicable Law to pursue such action.

14.4.4    Recoveries.  Any recoveries resulting from an enforcement action relating to a claim of Product Infringement in the Territory or Ex-Territory Infringement outside of the Territory will be first applied against payment of each Party’s costs and expenses in connection therewith.  Any such recoveries in excess of such costs and expenses will be split as follows: (a) [***] will be paid to the Party initiating such suit, action or proceeding and (b) [***] will be paid to the non-initiating Party.

14.4.5    Continuing Infringement.  With respect to any continuing Product Infringement of the Blueprint Patent Rights or the Joint Collaboration Patent Rights (other than Blueprint/CStone Combination Patent Rights) in a region in the Territory, if (a) Blueprint or its designee fails to abate such infringement or file an action to abate such infringement within [***] after receiving CStone’s written request pursuant to Section 14.4.2(a) (First Right; Step-In), or if Blueprint discontinues the prosecution of any such action after filing without abating such infringement, and (b) CStone notifies Blueprint that it wishes to exercise its right to enforce the applicable Patent Rights against such Product Infringement pursuant to Section 14.4.2(a) (First Right; Step-In), and Blueprint provides notice to CStone that Blueprint has a reasonable rationale for denying such exercise in accordance with Section 14.4.2(a)(i) (Blueprint First Right) (which notice must be provided to CStone within [***] from the date of CStone’s notice to Blueprint pursuant to Section 14.4.2(a) (First Right; Step-In)), then, from the date of such notice from Blueprint pursuant to Section 14.4.2(a)(i) (Blueprint First Right) until such time as such Product Infringement is abated such Patent Right will cease to be a Royalty Patent Right for purposes of this Agreement.

14.5       Infringement of Third Party Rights.

14.5.1    Notice.  If any Collaboration Product used or sold by CStone or its Affiliates or Sublicensees becomes the subject of a Third Party’s claim or assertion of infringement of a Patent Right or other rights in the Territory that are owned or controlled by such Third Party, then CStone will promptly notify Blueprint within [***] after receipt of such claim or assertion and will include in such notice a copy of any summons or complaint (or the equivalent thereof) received regarding the foregoing.  Thereafter, the Parties will promptly meet to consider the claim or assertion and the appropriate course of action and may, if appropriate, agree on and enter into a “common interest agreement” wherein the Parties agree to their shared, mutual interest in the outcome of such potential dispute.  The Parties will assert and not waive the joint defense privilege with respect to any communications between the Parties in connection with the defense of such claim or assertion.

14.5.2    Defense.  CStone will be solely responsible for the defense of any such infringement claims brought against CStone, at CStone’s cost and expense; provided that CStone will not agree to any settlement, consent to judgment, or other voluntary final disposition in connection with such defense action without Blueprint’s prior written consent if such settlement, consent to judgment, or other voluntary final disposition would (a) result in the admission of any liability or fault on behalf of Blueprint, (b) result in or impose any payment obligations upon Blueprint, or (c) subject Blueprint to an injunction or otherwise limit Blueprint’s ability to take any actions or refrain from taking any actions under this Agreement or with respect to any Blueprint Compound or Blueprint Product.  CStone will

keep Blueprint informed on the status of such defense action, and Blueprint will have the right, but not the obligation, to participate and be separately represented in such defense action at its sole option and at its own expense.

14.6       Patents Licensed from Third Parties.  Each Party’s rights under this Article 14 (Intellectual Property) with respect to the Patent Prosecution and enforcement of any Blueprint Patent Right that is in-licensed by Blueprint from a Third Party will be subject to the rights of such Third party to prosecute, enforce, and defend such Patent Right.

14.7       Patent Listings.  With respect to patent listings in any patent listing system established by any applicable Regulatory Authority in a region in the Territory during the Term that is similar to the FDA Orange Book, for issued patents for any Collaboration Product, the Parties will agree which patents to list in such patent listing (a) prior to the submission of the first and any subsequent MAA for such Collaboration Product in such region to such applicable Regulatory Authority, and (b) within [***] after the receipt of the first and any subsequent Regulatory Approval in such region for such Collaboration Product from such Regulatory Authority.

14.8       Patent Term Extensions.  With respect to any system for extending the term of Patent Rights in the Territory established by any applicable Regulatory Authority in any region in the Territory during the Term that is similar to the patent term extension system in the U.S., CStone will be solely responsible for making all decisions regarding patent term extensions in the Territory, including supplementary protection certificates and any other extensions that are now or become available in the future, that are applicable to Blueprint Patent Rights or Joint Collaboration Patent Rights licensed hereunder and that become available directly as a result of the Regulatory Approval of a Collaboration Product in the Territory; provided that CStone will consult with Blueprint with respect to such decisions and implement the reasonable comments and concerns of Blueprint.

14.9       Product Trademarks.

14.9.1    Global Brand Elements.  CStone acknowledges that Blueprint may decide to develop and adopt certain distinctive colors, logos, images, symbols, and trademarks to be used in connection with the Commercialization of each Collaboration Product on a global basis (such branding elements, collectively, the “Global Brand Elements”).  Blueprint will and hereby does grant CStone the exclusive right to use such Global Brand Elements in connection with the Commercialization of each Collaboration Product in the Territory.

14.9.2    Product Marks in the Territory.  CStone will have the right to brand the Collaboration Products in the Territory using trademarks, logos, and trade names that it determines appropriate for such Collaboration Products, which may vary by region or within a region, and that are consistent with Blueprint’s Global Brand Elements (the “Product Marks”); provided,  however, a Product Mark may deviate from Blueprint’s Global Brand Elements if (a) the JSC determines such Product Mark is not appropriate for the Territory due to linguistic reasons or market research showing that such Product Mark is not appropriate, or (b) in CStone’s reasonable discretion if a Governmental Authority rejects or refuses such Product Mark for use in the Territory.  CStone will provide Blueprint with a reasonable opportunity to review and provide comments on each proposed Product Mark, and CStone will consider [***] and incorporate [***] Blueprint’s comments before selecting any Product Mark.  CStone will not use any trademarks of Blueprint (including Blueprint’s corporate name) or any trademark confusingly similar thereto without Blueprint’s prior written consent.

14.9.3    Ownership.  Blueprint will be the sole and exclusive owner of all Product Marks and Global Brand Elements, including all trademark registrations and applications therefor and all goodwill associated therewith. To the extent CStone acquires any rights, title, or interests in or to any Product Mark or Global Brand Element (including any trademark registration or application therefore or goodwill associated with any Product Mark), CStone will, and hereby does, assign the same to Blueprint.  Blueprint will and hereby does grant CStone the exclusive right to use such Product Marks in connection with the Commercialization of the applicable Collaboration Product in the Territory.  CStone will register and maintain the Product Marks in the Territory that it determines reasonably necessary in Blueprint’s name, at CStone’s cost and expense.

14.9.4    Use.  CStone agrees that it and its Affiliates and Sublicensees will Commercialize each of the Collaboration Products in the Territory in a manner consistent with the Global Brand Elements and will: (a) ensure that all Collaboration Products that are sold bearing the Product Marks and Global Brand Elements are of a high quality consistent with industry standards for global pharmaceutical and biologic therapeutic products; (b) ensure that each use of the Global Brand Elements and Product Marks by CStone and its Affiliates and Sublicensees is accompanied by an acknowledgement that such Global Brand Elements and Product Marks are owned by Blueprint; (c) not use such Global Brand Elements or Product Marks in a way that might materially prejudice their distinctiveness or validity or the goodwill of Blueprint therein and includes the trademark registration symbol ® or ™ as appropriate; (d) not use any trademarks or trade names so resembling any of such Global Brand Elements or Product Marks as to be likely to cause confusion or deception; and (e) place and display the Global Brand Elements and the Product Marks on and in connection with the Collaboration Products in a way that acknowledges Blueprint’s role in discovering the Collaboration Products and that such Collaboration Product is under license from Blueprint.  To the extent permitted by Applicable Law, CStone will include the words (a) “Discovered by Blueprint Medicines Corporation” on all packaging and labeling for any Collaboration Product that is not a Blueprint/CStone Combination and in relevant scientific, medical, and other Collaboration Product-related communications to the extent such communications address the Development or Commercialization of such a Collaboration Product (that is not a Blueprint/CStone Combination), and (b) “Discovered in Collaboration by Blueprint Medicines Corporation and CStone Pharmaceuticals” on all packaging and labeling for any Blueprint/CStone Combination (to the extent feasible, for example, if the CStone Product and the Blueprint Product are co-packaged) and in relevant scientific, medical, and other Blueprint/CStone Combination-related communications to the extent such communications address the Development or Commercialization of a Blueprint/CStone Combination, in each case ((a) and (b)), or such other similar text provided by Blueprint and reasonably acceptable to CStone.

14.10     Patent Marking.  CStone will mark all Collaboration Products in accordance with the applicable patent marking laws, and will require all of its Affiliates and Sublicensees to do the same.  To the extent permitted by Applicable Law, CStone will indicate on the product packaging, advertisement and promotional materials that such Collaboration Product is in-licensed from Blueprint.

Article 15

TERM AND TERMINATION

15.1       Term.  This Agreement will be effective as of the Effective Date, and will continue, on a Collaboration Product-by-Collaboration Product and region-by-region basis, in effect until the expiration of the Royalty Term applicable to such Collaboration Product and such region (the

“Term”).  On a Collaboration Product-by-Collaboration Product and region-by-region basis, upon the natural expiration of this Agreement as contemplated in this Section 15.1 (Term), (a) the license granted to CStone under Section 2.1.1 (In the Territory) will become fully paid-up, perpetual and irrevocable, (b) the license granted to CStone under Section 2.1.2(b) (Outside the Territory) will convert to a worldwide license and will survive as a fully paid-up, perpetual, and irrevocable license, in each case ((a) and (b)), so long as at such time CStone has paid to Blueprint all amounts due under this Agreement in accordance with the terms hereof and is not at such time in breach of any obligation under this Agreement; and (c) the license granted to Blueprint under Section 2.3.2 (Outside the Territory) will convert to a worldwide license and will survive as a fully paid-up, perpetual, and irrevocable license.

15.2       Termination.

15.2.1    Termination by CStone for Convenience.  CStone may terminate this Agreement in its entirety or with respect to one or more Blueprint Products and all Collaboration Products that are Combination Regimens that include such Blueprint Product, in each case, by providing a written notice of termination to Blueprint after the first anniversary of the Effective Date that includes an effective date of termination [***]; provided,  however, CStone may terminate this Agreement with respect to a particular Collaboration Product at any time after the Effective Date by providing a written notice of termination to Blueprint [***].

15.2.2    Termination for Material Breach.

(a)         Notice and Cure Period.  If either Party believes in good faith that the other is in material breach of its material obligations hereunder, then the non-breaching Party may deliver notice of such breach to the other Party stating the cause and proposed remedy (“Breach Notification”).  For any breach arising from a failure to make a payment set forth in this Agreement, the allegedly breaching Party will have [***] from the receipt of the applicable Breach Notice to dispute or cure such breach.  If the Party receiving notice of breach fails to cure, or fails to dispute, that breach within the applicable period set forth above, then the Party originally delivering the Breach Notification may terminate this Agreement effective on written notice of termination to the other Party.  For all breaches other than a failure to make a payment as set forth in this Agreement, the allegedly breaching Party will have [***] from the date of the Breach Notification to dispute or cure such breach, provided that if such breach is not reasonably capable of cure within such [***] period, but is capable of cure within [***] from the date of such Breach Notification, then the breaching Party may submit, within [***] of such Breach Notification, a reasonable cure plan to remedy such breach as soon as possible and in any event prior to the end of such [***] period that is reasonably acceptable to the non-breaching Party, and, upon such submission, the [***] cure period will be automatically extended for so long as the breaching Party continues to use reasonable efforts to cure such breach in accordance with the cure plan, but for no more than [***].  [***]

(b)         Disputed Breaches.  If the allegedly breaching Party disputes in good faith the existence, materiality, or cure of the applicable material breach and provides written notice of such dispute to the other Party within the applicable period set forth above, then the matter will be addressed under the dispute resolution provisions in Article 16 (Dispute Resolution), and the termination will not become

effective unless and until it has been determined under Article 16 (Dispute Resolution) that the allegedly breaching Party is in material breach of any of its material obligations under this Agreement and has failed to cure the same.  During the pendency of such a dispute, all of the terms of this Agreement will remain in effect and the Parties will continue to perform all of their respective obligations hereunder.  The Parties stipulate and agree that a material breach of CStone’s diligence obligations set forth under Section 5.1 (Development Diligence and Responsibilities) or Section 9.1 (Commercialization Diligence Obligations), or of CStone’s payment obligations set forth under Article 10 (Payments), will be considered a material breach of a material obligation under this Agreement for purposes of this Section 15.2.2 (Termination for Material Breach).

15.2.3    Termination for Patent Challenge.  Except to the extent unenforceable under the Applicable Law, Blueprint may terminate this Agreement by providing written notice of termination to CStone if CStone or its Affiliates or Sublicensees (individually or in association with any Person) contests or assists a Third Party in contesting the scope, validity, or enforceability of any Blueprint Patent Right or Joint Collaboration Patent Right anywhere in the world in any court, tribunal, arbitration proceeding, or other proceeding, including the U.S. Patent and Trademark Office and the U.S. International Trade Commission (a “Patent Challenge”).  In the event of such a Patent Challenge, Blueprint will provide prompt written notice of such Patent Challenge to CStone, which notice must be provided [***] after the first filing of the petition to commence such proceeding, and Blueprint may terminate this Agreement by providing written notice of such termination to CStone within [***] after the conclusion of such Patent Challenge proceeding. If, based on the advice of counsel, Blueprint reasonably believes that termination of this Agreement pursuant to this Section 15.2.3 (Termination for Patent Challenge) is not an available remedy under Applicable Law, then [***].  Notwithstanding the foregoing, Blueprint will not have a right to terminate this Agreement [***] pursuant to this Section 15.2.3 (Termination for Patent Challenge) (a) with respect to any claim that Blueprint first asserts against CStone or any of its Affiliates or Sublicensees where the Patent Challenge is made by CStone or its Affiliates or Sublicensees in defense of such assertion by Blueprint, or (b) if such Patent Challenge was brought by a Sublicensee of CStone and CStone has terminated the sublicense agreement with such Sublicensee (or if CStone has provided such Sublicensee with written notice of such termination and is enforcing such termination) within [***] following Blueprint’s notice of such Patent Challenge.  To be effective, any notice of termination or notice of election to increase payments in lieu of termination pursuant to this Section 15.2.3 (Termination for Patent Challenge) must be provided to CStone in accordance with the time periods set forth under this Section 15.2.3 (Termination for Patent Challenge).  As used herein, a Patent Challenge includes: (i) filing an action under 28 U.S.C. §§ 2201-2202 seeking a declaration of invalidity or unenforceability of any such Patent Right; (ii) filing, or joining in, a petition under 35 U.S.C. § 311 to institute inter partes review of any such Patent Right; (iii) filing, or joining in, a petition under 35 U.S.C. § 321 to institute post-grant review of any such Patent Right or any portion thereof; (iv) filing or commencing any opposition, nullity, or similar proceedings challenging the validity of any such Patent Right in any country or region; or (v) any foreign equivalent of clauses (i), (ii), (iii), or (iv).

15.2.4    Cessation of Development and Commercialization.  If CStone and its Affiliates do not conduct any material Development or Commercialization activities with respect to one or more Collaboration Products [***]and such suspension of activity is not: (a) [***], (b)

[***] (c) [***], or (d) [***], then Blueprint may, at its election, terminate this Agreement with respect to the applicable Collaboration Product upon [***] prior written notice to CStone and such Collaboration Product (and the corresponding Blueprint Compound) will be a Terminated Product for purposes of this Agreement.  Notwithstanding the foregoing, if Blueprint gives a notice of termination to CStone pursuant to this Section 15.2.4 (Cessation of Development or Commercialization), and CStone provides notice during such [***] period that it disputes the basis for termination pursuant to this Section 15.2.4 (Cessation of Development or Commercialization), then this Agreement will not terminate unless and until an arbitrator issues a final award pursuant to Section 16.3 (Arbitration) upholding such basis for termination.

15.2.5    Termination for Insolvency.  Each Party will have the right to terminate this Agreement upon delivery of written notice to the other Party if (a) such other Party files in any court or agency pursuant to any statute or regulation of any jurisdiction a petition in bankruptcy or insolvency or for reorganization or similar arrangement for the benefit of creditors or for the appointment of a receiver or trustee of such other Party or its assets, (b) such other Party is served with an involuntary petition against it in any insolvency proceeding and such involuntary petition has not been stayed or dismissed within [***] of its filing, or (c) such other Party makes an assignment of substantially all of its assets for the benefit of its creditors.

15.2.6    Full Force and Effect During Notice Period.  This Agreement will remain in full force and effect until the expiration of the applicable termination notice period.  For clarity, if CStone or any of its Affiliates or Sublicensees achieve any Milestone Event during the termination notice period, then the corresponding Milestone Payment is accrued and CStone will remain responsible for the payment of such Milestone Payment even if the due date of such Milestone Payment occur after the effective date of the termination.

15.3       Effect of Termination.  Upon the termination of this Agreement:

15.3.1    Licenses.  As of the effective date of termination of this Agreement with respect to a Terminated Product, except for the license granted to CStone under Section 2.1.2(b) (and any sublicenses granted under such rights), all licenses and all other rights granted by Blueprint to CStone under the Blueprint Technology for such Terminated Product will terminate and all sublicenses granted by CStone pursuant to Section 2.2 (Sublicensing and Subcontractors) with respect to such Terminated Product will also terminate; provided,  however, that at the request of any Sublicensee who is in good standing under and not in breach of its applicable sublicense agreement, Blueprint will enter into good faith negotiations with any such Sublicensee with respect to potentially entering into a direct license agreement with such Sublicensee.  Each Party will retain its joint ownership interests in the Joint Collaboration Technology.  In addition, upon the termination of this Agreement with respect to one or more Terminated Products that are Blueprint Products or Blueprint Combination Products Blueprint will have, and CStone hereby grants to Blueprint, effective upon such termination, a worldwide, exclusive, fully-paid, royalty-free, perpetual, irrevocable, and sublicenseable (through multiple tiers) license under the CStone General Collaboration Technology, CStone Product Collaboration Technology, CStone’s interests in the Joint Collaboration Technology and any CStone Identified Rights Controlled by CStone as of the effective date of such termination, in each case, to Exploit such Terminated Products that are Blueprint Products or Blueprint Combination Products (as applicable).  In addition, CStone will assign to Blueprint any Third Party IP Agreement pursuant to which CStone then Controls any CStone Identified Rights, if

permitted under such Third Party IP Agreement (and will use reasonable efforts to seek any consent required from the applicable Third Party in connection with such an assignment). If such Third Party IP Agreement cannot be assigned to Blueprint, then upon Blueprint’s reasonable request, CStone will maintain such Third Party IP Agreement and Blueprint will pay to CStone [***] of all payments due to the applicable Third Party under any such Third Party IP Agreement in consideration of the sublicense to Blueprint and Blueprint’s Exploitation of such CStone Identified Rights. If CStone is unable to sublicense any CStone Identified Rights to Blueprint pursuant to this Section 15.3.1 (Effect of Termination; Licenses) without the consent of the Third Party, then CStone undertakes, on request from Blueprint, to use reasonable efforts to procure such licenses with respect to the applicable Terminated Product that is a Blueprint Product or Blueprint Combination Product on behalf of Blueprint to the extent that it is able to do so, and Blueprint will pay such fees and agree to be bound by the terms agreed between CStone and the Third Party licensor.

15.3.2    Appointment as Exclusive Distributor.  If CStone is Commercializing any Terminated Product in any region in the Territory as of the effective date of termination of this Agreement with respect to such Terminated Product, then, at Blueprint’s election (in its sole discretion) on a region-by-region basis in the Territory, until such time as all Regulatory Approvals with respect to such Terminated Product in such region have been assigned and transferred to Blueprint, either (a) CStone will appoint Blueprint or its designee as its exclusive distributor of such Terminated Product in such region and grant Blueprint or its designee the right to appoint sub-distributors, to the extent not prohibited by any written agreement between CStone or any of its Affiliates and a Third Party; provided that Blueprint will purchase any and all salable inventory of the Terminated Product held by CStone or its Affiliates as of the effective date of termination with respect to such Terminated Product at a price equal to [***], or (b) CStone will have the continued right to sell the Terminated Product in such region from its inventory; provided, however, that CStone’s obligations under this Agreement with respect to all such Terminated Product that CStone sells, including the obligation to remit Royalty Payments to Blueprint hereunder, will continue in full force and effect during such period.

15.3.3    Regulatory Submissions and Regulatory Approvals.  To the extent requested by Blueprint following the date that a Party provides notice of termination of this Agreement with respect to a Terminated Product, CStone will and hereby does, and will cause its Affiliates and Sublicensees to, (a) [***], assign and transfer to Blueprint or its designee all of CStone’s rights, title, and interests in and to all Regulatory Submissions and Regulatory Approvals for such Terminated Product then owned or Controlled by CStone or any of its Affiliates or Sublicensees, and (b) to the extent assignment pursuant to clause (a) is delayed or is not permitted by the applicable Regulatory Authority, permit Blueprint to cross-reference and rely upon any Regulatory Submissions and Regulatory Approvals filed by CStone with respect to such Terminated Product.  CStone will take all steps necessary to transfer ownership of all such assigned Regulatory Submissions and Regulatory Approvals to Blueprint, including submitting to each applicable Regulatory Authority a letter or other necessary documentation (with a copy to Blueprint) notifying such Regulatory Authority of the transfer of such ownership of each Regulatory Submission and Regulatory Approval.  In addition, upon Blueprint’s written request, CStone will, at its cost and expense (unless this Agreement is terminated by CStone pursuant to Section 15.2.2 (Termination for Material Breach) or Section 15.2.5 (Termination for Insolvency), in which case Blueprint will bear all such costs and expenses), provide to Blueprint copies of all material related documentation, including

material non-clinical, preclinical, and clinical data that are held by or reasonably available to CStone or its Affiliates or Sublicensees.  The Parties will discuss and establish appropriate arrangements with respect to safety data exchange, provided that Blueprint will assume all safety and safety database activities with respect to any Terminated Product no later than [***] after the effective date of termination of this Agreement with respect to such Terminated Product.

15.3.4    Assignment and Disclosure.  To the extent requested by Blueprint following the date that a Party provides notice of termination of this Agreement with respect to a Terminated Product, CStone will promptly upon request (and in any event within [***]):

(a)         assign and transfer to Blueprint or its designee all of CStone’s rights, title, and interests in and to all clinical trial agreements, manufacturing and supply agreements, and distribution agreements (to the extent assignable and not cancelled), confidentiality and other agreements, data and other Know-How  (including commercial information) in CStone’s Control, in each case, relating to such Terminated Product and that are necessary or useful for the Exploitation of such Terminated Product;

(b)         disclose to Blueprint or its designee all documents, records, and materials related to such Terminated Product that are controlled by CStone or that CStone is able to obtain using reasonable efforts, and that embody the foregoing; and

(c)         assign and transfer to Blueprint or its designee all of CStone’s rights, title, and interests in and to any promotional materials, training materials, medical education materials, packaging and labeling, and all other literature or other information related to such Terminated Product and copyrights and any registrations for the foregoing.

Unless this Agreement is terminated by CStone pursuant to Section 15.2.2 (Termination for Material Breach) or Section 15.2.5 (Termination for Insolvency), the costs and expenses associated with the assignments set forth in this Section 15.3.4 (Assignment and Disclosure) will be borne by CStone.  To the extent that any agreement or other asset described in this Section 15.3.4 (Assignment and Disclosure) is not assignable by CStone, then such agreement or other asset will not be assigned, and upon the request of Blueprint, CStone will take such steps as may be necessary to allow Blueprint to obtain and to enjoy the benefits of such agreement or other asset, without additional payment therefor, in the form of a license or other right to the extent CStone has the right and ability to do so.  For clarity, Blueprint will have the right to request that CStone take any or all of the foregoing actions in whole or in part, or with respect to all or any portion of the assets set forth in this Section 15.3.4 (Assignment and Disclosure).
