applicable), (b) the sublicense is subject and subordinate to the terms and conditions of this Agreement, (c) the sublicense cannot be further sublicensed and (d) the sublicense shall terminate upon termination or expiration of this Agreement as provided in Article X. Copies of all sublicense agreements shall be provided to ARCA within fifteen (15) days of execution thereof. LabCorp hereby assumes responsibility for the performance of all obligations so imposed on its sublicensees by this Agreement and will itself pay and account to ARCA for all payments and reports due under this Agreement which may accrue by reason of the operations of each sublicense, as if it were LabCorp’s own commercial activity.

2.7 Right of First Refusal for Canada. During the term of this Agreement, ARCA shall provide LabCorp with written notice prior to the first occasion that ARCA solicits any interest in, makes any offers for, or engages in any negotiations with any other Persons with respect to, any rights to make, have made, perform, use, sell, offer for sale, or import Diagnostic Tests (in the form of a Homebrew Assay, IVD Product or IVD Kit) in Canada for use in the Field. Upon LabCorp’s receipt of such notice and for a period of ninety (90) days thereafter, ARCA agrees to have good faith, exclusive negotiations with LabCorp regarding a possible license or other transfer of such rights to LabCorp with respect to Canada (under terms no less favorable than those set forth in this Agreement), unless LabCorp notifies ARCA that it is not interested in such rights. If no agreement is entered into between ARCA and LabCorp during this ninety (90) day period, ARCA shall be permitted to negotiate with Third Parties and enter into agreement(s) with Third Parties relating to such rights in Canada with terms that are no less favorable to ARCA than those offered to LabCorp. However, ARCA shall not negotiate or enter into agreement(s) with Third Parties with terms that are less favorable to ARCA than those offered to LabCorp, unless ARCA first offers such terms to LabCorp in writing and allows LabCorp a period of thirty (30) days after receipt of such terms to accept or reject such terms.

2.8 Rights of LabCorp Affiliates under CardioDx Agreement. The LabCorp Affiliates listed on Exhibit A hereto shall be included within the sublicense granted under Section 2.1 subject to the approval of CardioDx.

ARTICLE IV

DEVELOPMENT PHASE

4.1 Scope. LabCorp shall commence and diligently pursue the development of the Commercial Platform, as more particularly set forth in this Article IV, and use commercially reasonable efforts to: 1) legally market the Commercial Platform within a time period thereafter to be agreed upon by the Parties, but in any case by the time the Drug Product is first available for commercial sale in the Territory; and 2) obtain Regulatory Approval of the Commercial Platform by the date of first commercial sale of the Drug Product or as soon as reasonably practical thereafter. LabCorp will have executive and financial responsibility for development of the Commercial Platform. The Parties will cooperate in an effort to obtain Regulatory Approval as described below.

Development, Commercialization and Licensing Agreement-Confidential-Page 10

4.2 Development of Commercial Platform. LabCorp will be responsible for using commercially reasonable efforts to design and develop the Commercial Platform. The Parties anticipate that the Commercial Platform will utilize the least-intrusive procedure that is practical and commercially reasonable, such as a blood-based and/or buccal swab procedure. LabCorp will use commercially reasonable efforts to obtain Regulatory Approval of the Commercial Platform (i.e., as an IVD Product) prior to the first commercial sale of the Drug Product in the Territory, but the Parties acknowledge that the Commercial Platform may be available commercially only in the form of a Homebrew Assay, that has not received Regulatory Approval, by the time of first commercial sale. The Parties anticipate initially seeking Regulatory Approval of the Commercial Platform as a centralized, laboratory procedure, and later as an IVD Kit that can be performed in a de-centralized fashion by LabCorp or by Third Parties, as discussed below. The Parties will use reasonable commercial efforts to obtain a Regulatory Approval of the Commercial Platform that will permit (among other things) ARCA and LabCorp to market the usefulness of the Diagnostic Tests in determining the appropriateness of, and the clinical outcomes expected from use of the Drug Product, and to reference the Commercial Platform in the labeling of the Drug Product. ARCA will consult with LabCorp, as needed, in order to facilitate the development of the Commercial Platform. The Commercial Platform, and any amendments or modifications thereto, will be subject to ARCA’s commercially reasonable approval.

4.3 Regulatory Plan. ARCA, in consultation with LabCorp, will develop a regulatory plan (the “Regulatory Plan”). The purpose of the Regulatory Plan is to provide the Parties with an outline of the overall strategy and timelines, and identifying documentation necessary to obtain, Regulatory Approval of the Drug Product and the Commercial Platform, and the degree to which the Regulatory Approval of the Commercial Platform will be integrated with that of the Drug Product. The development, approval, commercialization and promotion of the Drug Product shall be the sole responsibility of ARCA. The Parties acknowledge that, based on the guidance of Regulatory Authorities, Regulatory Approval of the Drug Product and the Commercial Platform may be sought through submissions to Regulatory Authorities under a single application, whether as a Combination Product or through some other combination of use as may be permitted or required by Regulatory Authorities, or under separate applications. To the extent that Regulatory Approval of the Drug Product and the Commercial Platform are sought through separate applications, consistent with the guidance of Regulatory Authorities, LabCorp and ARCA agree to develop the Regulatory Plan to support each other’s separate submissions; provided, that the final content of the Plan shall remain within ARCA’s control and discretion, and further provided that those portions of the Regulatory Plan concerning the Diagnostic Tests and the design and development of the Commercial Platform (including the IVD Product and the IVD Kit), and any amendments or modifications thereto, will be subject to LabCorp’s commercially reasonable approval. The marketing of the Homebrew Assay, if made available, shall be solely the responsibility of LabCorp and shall not be inconsistent with the Regulatory Plan for the commercialization of the IVD Product and IVD Kit. The Regulatory Plan will be completed within one hundred twenty (120) days of the date hereof and will clearly indicate:

(a) Whether Regulatory Approval will be sought in the United States for the Drug Product and the Commercial Platform under a single application or under separate applications;

Development, Commercialization and Licensing Agreement-Confidential-Page 11

(b) Alternative strategies for obtaining Regulatory Approval of the Drug Product and the Commercial Platform, as may be reasonable;

(c) The [ * ] (where applicable), estimated timelines, duties and parties responsible for each stage of seeking Regulatory Approval for the Drug Product and the Commercial Platform, including the timing of each submission required to obtain Regulatory Approval;

(d) Proposed labeling for the Drug Product and the Commercial Platform;

(e) Procedures for providing documentation to each Parry of written or oral communications to or from Regulatory Authorities related to Regulatory Approval of the Drug Product and the Commercial Platform; and

(f) The projected date for commercial launch in the Territory of the Drug Product and the Commercial Platform.

4.4 Regulatory Approval; Assistance with Regulatory Submissions

(a) If Regulatory Approval of the Drug Product and the Commercial Platform is initially sought under one application, whether as a Combination Product or through some other combination of use as may be permitted or required by Regulatory Authorities, ARCA will have primary responsibility for the preparation and submission of the single application to Regulatory Authorities.

(c) ARCA’s obligations and responsibilities under this Agreement will be performed in a competent manner in conformance with the standard of care usually and reasonably expected in the performance of such activities, and in compliance with all applicable, federal, state and local laws, rules and regulations, as interpreted and enforced by Regulatory Authorities. Notwithstanding anything in this Agreement, ARCA shall not have any obligation or responsibility to perform any activity that is contrary to applicable federal, state and local laws, rules and regulations, as interpreted and enforced by Regulatory Authorities, including the guidance of Regulatory Authorities with respect to the legal marketing of the Commercial Platform.

(d) ARCA provided a ROFN Notice (as defined in Section 3.1(b) of the CardioDx Agreement) to CardioDx, CardioDx provided a Notice of Interest (as defined Section 3.1(c) of the CardioDx Agreement), and ARCA and CardioDx did not enter into a letter of intent or definitive agreement within the Negotiation Period (as defined Section 3.1(c) of the CardioDx Agreement), which expired prior to the Effective Date of this Agreement. Accordingly, the Right of First Negotiation (as defined in Section 3.1(a) of the CardioDx Agreement) has terminated and CardioDx has no further rights under Section 3.1 of the CardioDx Agreement.

11.1 LabCorp Indemnification. LabCorp hereby agrees to save, defend, and hold ARCA and its agents and employees harmless from and against any and all suits, claims, actions, demands, liabilities, expenses and/or loss, including reasonable legal expense and attorneys’ fees (“Losses”) resulting from: [ * ].

11.2 ARCA Indemnification. ARCA hereby agrees to save, defend, and hold LabCorp and its agents and employees harmless from and against any and all Losses resulting from: (i) breach by ARCA or its Affiliates in the performance of its obligations under this Agreement (except in the case where exclusive remedies are specified for such breach); (ii) negligence or willful misconduct on the part of ARCA or its Affiliates; (iii) the manufacture, use, handling, storage, sale, distribution, or other disposition of the Drug Product by ARCA, its Affiliates, agents, or sublicensees; and (iv) claims that the development, manufacture, performance, use, sale or importation of the Diagnostic Tests interferes with or infringes any intellectual property rights owned or possessed by any Third Party, but only to the extent LabCorp is not indemnified against such claims under the LabCorp CardioDx Agreement (if applicable), and only to the extent such claims are based on intellectual property rights licensed hereunder.

11.3 Indemnification Procedures. A Party (the “Indemnitee”) which intends to claim indemnification under this Section shall notify the other Party (the “Indemnitor”) within a reasonable time in writing of any action, claim or liability in respect of which the Indemnitee believes it is entitled to claim indemnification, provided that the failure to give timely notice to the Indemnitor shall not release the Indemnitor from any liability to the Indemnitee to the extent the Indemnitor is not prejudiced thereby.

The Party not assuming the defense of any such claim shall render all reasonable assistance to the Party assuming such defense upon request, and all reasonable out-of-pocket costs of such assistance shall be for the account of the Indemnitor. No such claim shall be settled other than by the Party defending the same, and then only with the consent of the other Party which shall not be unreasonably withheld; provided that the Indemnitee shall have no obligation to consent to any settlement of any such action or claim which imposes on the Indemnitee any liability or obligation which cannot be assumed and performed in full by the Indemnitor, and the Indemnitee shall have no right to withhold its consent to any settlement of any such action or claim if the settlement involves only the payment of money by the Indemnitor or its insurer.

Within ten (10) days following the Hearing, the Panel will present its decision (“Decision”) in writing, acting with the concurrence of at least two Arbitrators, which will choose the resolution requested by one of the Parties (or if the Panel desires, offers a resolution other than either resolution requested by the Parties), together with a statement in reasonable detail of the reasons therefor.

12.4 Fees and Costs of the Arbitration. Each Party shall bear its own costs of the Arbitration (including any Referee Hearing), but will share equally for payment of the fees and costs of the Panel and of any Referee.

12.5 Waivers or Alterations to the Dispute Resolution Procedure. The Parties may mutually agree in writing to waive or alter aspects of these Arbitration provisions in any Arbitration.
