2.	SCOPEOF WORK

2.1 Scope of Agreement. As a master form of contract, this Agreement allows the parties to contract for multiple Projects through the issuance of multiple Work Orders (as discussed in Section 2.2 below), without having to re-negotiate the basic terms and conditions contained herein.

2.2 Performance of Services. The specific Services to be performed by BaySide and the protocols to be provided by Ventyx for each project under this Agreement (each, a “Project”) will be specified separately in writing on terms and in a form acceptable to the parties (each such writing, a “Work Order”). Each Work Order will be signed by both parties and will set forth, upon terms mutually agreeable to the parties, the specific Services to be performed by BaySide, the time line and schedule for the performance of such Services and the compensation to be paid by Ventyx to BaySide for the provision of such Services, as well as any other relevant terms and conditions. If a Project includes the development of specific Work Product, the specifications of such Work Product will be set forth in the relevant Work Order. Each Work Order will be subject to the terms and conditions of this Agreement, in addition to the specific details set forth in such Work Order. To the extent any terms or provisions of a Work Order conflict with the terms or provisions of this Agreement, the terms and provisions of this Agreement will control. The parties will attach a copy of each Work Order to Exhibit A of this Agreement and each such Work Order will be incorporated herein by reference. Any changes to such Work Order will be in writing, executed by each party, attached to the original Work Order and incorporated therein and attached hereto.

2.3 Compliance with Work Orders and Law. BaySide agrees to perform the Services set forth in each Work Order in a competent and professional manner and in strict accordance with the terms and conditions contained in this Agreement and such Work Order. BaySide will perform its obligations hereunder in conformance with all applicable federal, state and local statutes, rules and regulations and, if applicable, accepted standards of good laboratory practice (GLP), good clinical practice (GCP) and/or current good manufacturing practice (cGMP).

2.4 Ventyx’s Approval of Subcontractors. BaySide will not subcontract any of the Services under any Work Order without first obtaining Ventyx’s prior written consent. BaySide will at all times be responsible for the compliance of its permitted subcontractors with the terms and conditions of this Agreement and the applicable Work Order.

2.5 Results. All data generated by BaySide or its employees, agents, consultants, Ventyx-approved subcontractors or other representatives in the course of conducting a Project, whether in written, graphic or electronic form or contained in any computer database in any computer readable form (collectively, the “Results”), will be owned solely by Ventyx. BaySide will record, or cause to be recorded, all Results in a timely, accurate and complete manner. All

Results collected will be delivered to Ventyx by BaySide in a timely manner throughout the performance of the Project, and in no event later than ten (10) working days after the date of completion or termination of such Project or later than ten (10) working days after the date on which Ventyx otherwise requests delivery of the Results. Ventyx will have the right to review, publish, disclose and use any Results as Ventyx, in its sole discretion, deems appropriate, including, without limitation, in submission to any U.S. or foreign regulatory authority. Any copyrightable work created in connection with the performance of a Project and contained in or relating to the Results will be considered a work made for hire, whether published or unpublished, and all rights therein will be the property of Ventyx as author and owner of copyright in such work. For purposes of clarification, this section will apply to each Project individually.

2.6 Materials. Ventyx may provide to BaySide certain materials necessary for performance of a Project as specified in the applicable Work Order, which may include, without limitation, Ventyx Product (collectively, “Materials”), in amounts sufficient for the conduct of the Project. All such Materials will remain the sole property of Ventyx, will be used only in furtherance of the Services in accordance with this Agreement and each Work Order, will not be used or delivered to or for the benefit of any third party without the prior written consent of Ventyx, and will be used in compliance with all applicable laws, rules and regulations. The Materials supplied by Ventyx under this Agreement must be used with prudence and appropriate caution in any experimental work because not all of their characteristics may be known. Except as expressly set forth herein, THE MATERIALS ARE PROVIDED “AS IS” AND WITHOUT ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, INCLUDING, WITHOUT LIMITATION, ANY IMPLIED WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR ANY PARTICULAR PURPOSE OR ANY WARRANTY THAT THE USE OF THE MATERIALS WILL NOT INFRINGE OR VIOLATE ANY PATENT OR OTHER PROPRIETARY RIGHTS OF ANY THIRD PARTY.

3.	PAYMENT

BaySide will provide to Ventyx for each Work Order one or more invoices (to be delivered at intervals agreed upon in such Work Order), summarizing the Services performed during such specific period of time under such Work Order and the fees and costs therefor. BaySide will invoice Ventyx for all amounts due in United States Dollars. Ventyx will pay all undisputed amounts within thirty (30) days after receipt of a proper invoice and reasonable supporting documentation for such invoice.

4.2 Visits by Ventyx. Representatives of Ventyx may visit and/or meet with BaySide or Ventyx-approved subcontractors at reasonable times and with reasonable frequency during normal business hours to observe the progress of each Project and review Project records. BaySide will assist Ventyx in scheduling such visits.

4.3 Record-Keeping. BaySide will maintain records of documents, information, data and materials used or generated in performance of the Services (including, without limitation, Work Product and Intellectual Property) in a professional manner so as to permit Ventyx to review such records in accordance with this Section 4.3 without disclosing to Ventyx any third party confidential or proprietary information. Designated representatives of Ventyx will, upon reasonable notice to BaySide, have access to and will be permitted to review all such records. BaySide will provide to Ventyx upon request a copy of all such records. Following expiration or termination of this Agreement, BaySide will (a) continue to make such records available to Ventyx for a period of five (5) years from the date of such termination, or (b) upon Ventyx’s prior written request, transfer ownership of such records to Ventyx. After expiration of such retention period, BaySide will either transfer such records to Ventyx or destroy such records as determined by Ventyx in its sole discretion. This Section 4.3 is subject to any provision of the applicable Work Order providing for BaySide to deliver any such records to Ventyx.

5.	OWNERSHIP OF INTELLECTUAL PROPERTY

BaySide understands and agrees that the underlying rights to the intellectual property and materials that are the subject of each Work Order, including, without limitation, all intellectual property rights in Ventyx Products, are owned solely by Ventyx. Neither BaySide nor any Ventyx- approved subcontractor will acquire any rights of any kind whatsoever with respect to Ventyx Products as a result of conducting a particular Project. All rights to Work Product generated in the performance of work conducted under this Agreement by BaySide’s employees, agents, consultants, subcontractors or other representatives, either solely or jointly with employees, agents, consultants or other representatives of Ventyx, including all patent and other intellectual property rights therein (the “Intellectual Property”), will be owned solely by Ventyx.

BaySide will promptly disclose to Ventyx any such Work Product arising under this Agreement. Ventyx may, in its sole discretion, file and prosecute in its own name and at its own expense, patent applications on any patentable inventions within the Work Product. Upon the request of Ventyx, and at the sole expense of Ventyx, BaySide will assist Ventyx in the preparation, filing and prosecution of such patent applications and will execute and deliver any and all instruments necessary to effectuate the ownership of such patent applications and to enable Ventyx to file and prosecute such patent applications in any country.
