Capitalized terms used in this Participation Agreement and not otherwise defined herein shall have the meanings ascribed to them in the Plan. The Company considers the severance benefits offered under the Plan to be an important part of our overall executive compensation program and consistent with competitive market practice. We believe that providing appropriate severance benefits helps to attract and retain highly qualified executives by providing income continuity in the event of an involuntary termination of employment. These arrangements also allow the Company Group to protect its interests through corresponding confidentiality, non-solicitation, noncompetition and other restrictive covenants. In order to be eligible to receive the severance benefits set forth in the Plan, you must execute the Restrictive Covenant Agreement attached hereto as Appendix A. You are hereby notified in accordance with the Defend Trade Secrets Act of 2016 that you will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (a) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. You are further notified that if you file a lawsuit for retaliation by the Company for reporting a suspected violation of law, you may disclose the Company’s trade secrets to your attorney and use the trade secret information in the court proceeding if you: (a) file any document containing the trade secret under seal; and (b) do not disclose the trade secret, except pursuant to court order. By accepting this Participation Agreement, you hereby acknowledge, agree and confirm that: 1. You have received a copy of the Plan and have read, understand and are familiar with the terms and provisions of the Plan; 2. Except as provided below, the Plan supersedes and replaces the severance provisions of any existing severance arrangement (or other agreement providing for severance benefits), whether written or unwritten, to which you are a party (each, a “Prior Severance Agreement”) including, for the avoidance of doubt, the severance provisions set forth in the Contract of Employment, dated as of July 11, 2025, by and between you and VWR International Ltd. Notwithstanding the foregoing, the Plan shall not supersede the terms of any equity award agreements that include more favorable vesting treatment of awards upon a Termination of Employment. You agree that each Prior Severance Agreement is hereby rendered null and void and no longer in effect. You further agree that in no circumstances Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
A-2 are you or will you be eligible to receive severance benefits of any kind under a Prior Severance Agreement; 3. The employment relationship between yourself and the Company (or any Group Company that employs you) is an “at-will” relationship; 4. In order to obtain certain of the severance benefits provided for in the Plan, you will be required to execute, deliver, and not thereafter revoke, a Separation and Release Agreement, which will contain, among other things, certain restrictive covenants to which you will be subject; 5. Disputes and disagreements regarding your right to severance benefits under the Plan are governed by a claims procedure set forth in Section 9 of the Plan, which you must follow; and 6. The Company has the unilateral right, in its sole discretion, to offset the payment of benefits to you under the Plan against amounts due from you under the Company’s clawback/recoupment policy as in effect from time to time and against any other amounts that you owe to the Company Group. You acknowledge that: (a) the Plan confers significant legal rights and obligations; (b) the Company has encouraged you to consult with legal and financial advisors as appropriate; and (c) you have had adequate time to consult with such advisors before executing this Participant Agreement.

Employee acknowledges and agrees that Avantor will suffer immediate and irreparable harm and that money damages will not be adequate to compensate Avantor or to preserve the status quo. Therefore, Employee hereby consents to the issuance of a temporary restraining order and other injunctive relief necessary to enforce this Agreement. (B) The duration of any injunction will be increased in an amount equal to any period of time during which Employee failed to comply with the covenants contained in this Agreement. (C) In any proceeding alleging breach of this Agreement, Avantor and Employee each will have the right to engage in deposition and document discovery, and Avantor will have the right to conduct forensic examination(s) of any computers and/or electronic devices in Employee’s possession or control, if Avantor reasonably believes such devices contain Confidential Information or other Avantor property. In connection with any application for injunctive relief to enforce this Agreement (including without limitation any application for temporary and/or Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
Appendix A-9 preliminary injunctive relief), the foregoing discovery will be conducted on an expedited basis, including expedited document and deposition discovery. Section 1.9 Notice of Agreement Employee will tell any prospective new employer, partner in a business venture, investors, and/or any entity seeking to engage Employee’s services, prior to accepting employment, engagement as a consultant or contractor, or engaging in a business venture, that this Agreement exists, and further, Employee will provide a true and correct copy of this Agreement to any such individual or entity prior to accepting any such employment or entering into any such engagement or business venture. Further, Employee authorizes Avantor to provide a copy of this Agreement to any such entity(ies) or individual(s). Section 1.10 Modification & Severability; Other Restrictive Covenants If any section, provision, paragraph, phrase, word, and/or line (collectively “Provision”) of this Agreement is held to be unenforceable, then this Agreement will be deemed amended to the extent necessary to render the otherwise unenforceable Provision, and the rest of the Agreement, valid and enforceable. If a court declines to amend this Agreement as provided herein, the invalidity or unenforceability of any Provision of this Agreement will not affect the validity or enforceability of the remaining Provisions, which will be enforced as if the offending Provision had not been included in this Agreement. If one or more post-employment restrictive covenants in this Agreement are found unenforceable (despite, and after application of, any applicable right to reformation that could add or renew enforceability), then any provision(s) of any prior agreement between the parties that would provide for restriction(s) on the same or substantially similar post-employment conduct of Employee will not be considered superseded and will remain in effect, to the extent enforceable. Therefore, on a going forward basis, this Agreement will be read in conjunction with all prior and future agreements, to the extent enforceable, on the same subject matter so as to afford Avantor the broadest protections allowed under applicable law. 2. Additional Terms Section 2.1 Cooperation Employee will cooperate fully with Avantor and Avantor’s legal counsel in connection with any action, proceeding, or dispute arising out of matters with which Employee was directly or indirectly involved while serving as an employee of Avantor, its predecessors, subsidiaries, or affiliates. This cooperation will include, but will not be limited to, meeting with, and providing information to, Avantor and its legal counsel, maintaining the confidentiality of any past or future privileged communications with Avantor’s legal counsel (outside and in-house), and being available to testify truthfully by affidavit, in depositions, or in any other forum on behalf of Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
Appendix A-10 Avantor. Avantor agrees to reimburse Employee for any reasonable and necessary out- of-pocket costs associated with Employee’s cooperation. Section 2.2 Choice of Law, Jurisdiction, Venue, and Attorneys’ Fees (A) This Agreement will be governed by, construed, interpreted, and its validity determined under the law of the State of Employee’s last assigned work location for Avantor, without regard to such jurisdiction’s conflicts of laws principles. Such law will govern regardless of the venue in which a dispute may be adjudicated. (B) Unless Employee has an agreement with Avantor to arbitrate employment-related disputes, the exclusive and mandatory venue for adjudicating any disputes under this Agreement will be the federal court or state court having original jurisdiction for Employee’s last assigned work location for Avantor. Employee and Avantor hereby consent to jurisdiction in such court for such purpose, and Employee consents to service of process by mail in respect of any such suit, action or proceeding. If Employee has an agreement with Avantor to arbitrate employment- related disputes, any disputes relating to this Agreement will be resolved through arbitration pursuant to the arbitration agreement between Employee and Avantor. (C) Notwithstanding the foregoing, Employee and Avantor agree that any application for temporary restraining order and/or temporary or preliminary injunctive relief shall be adjudicated exclusively in the court of competent jurisdiction as set forth in Section 2.2(B) above, even if Employee and Avantor are parties to an arbitration agreement that otherwise includes disputes under this Agreement. Employee agrees that the injunctive relief to which Employee consents hereinabove, under the circumstances addressed in this section, shall be granted by a court of competent jurisdiction pending arbitration on the merits in order to preserve the status quo and/or prevent irreparable harm pending such arbitration. (D) In any legal proceeding to enforce this Agreement, the prevailing party will be entitled to reimbursement of its actual costs and expenses, including without limitation reasonable attorneys’ fees, costs, and disbursements. Section 2.3 Binding Effect and Assignability This Agreement will be binding upon and inure to the benefit of the parties hereto and their respective heirs, personal representatives, successors, assigns, affiliated entities, and any party- in-interest. Should Avantor be acquired by, merge with, or otherwise combine with another corporation or business entity, the surviving entity will have all rights to enforce the terms of this Agreement as if it were Avantor itself enforcing the Agreement. This Agreement may be enforced against Employee by any Avantor affiliate, without the need for any formal assignment of this Agreement. Employee may not assign this Agreement. Section 2.4 No Waiver of Rights; Amendment; Other Agreements Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
Appendix A-11 A waiver by Avantor of the breach of any of the provisions of this Agreement by Employee will not be deemed a waiver of any subsequent breach, nor will recourse to any remedy hereunder be deemed a waiver of any other or further relief or remedy provided for herein. No waiver will be effective unless made in writing and signed by an officer of Avantor. This Agreement can only be amended or modified in a writing signed by both parties. Any subsequent change(s) in Employee’s position, duties, salary, compensation, or benefits will not affect the validity or scope of this Agreement. This Agreement does not supersede or replace any prior agreements between the parties, including but not limited to any prior agreements that provide for restriction(s) on post- employment conduct. Any and all such prior Agreements remain in full force and effect, according to their terms, and to the extent enforceable under applicable law. Section 2.5 Electronic Signatures and Counterparts This Agreement may be executed via electronic signature or acceptance and in any number of counterparts (including facsimile counterparts or counterparts delivered by electronic transmission), each of which will be an original, and all of which together will constitute one instrument. Section 2.6 At-Will Employment This Agreement shall not constitute a contract for employment for any specific period of time. Either Avantor or Employee is free to terminate the employment relationship “at will” at any time, with or without cause, to the fullest extent permitted by law.

Exhibit B – Personal Services, Confidentiality, and Inventions Agreement See Attached Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
B-1 AVANTOR, INC. PERSONAL SERVICES, CONFIDENTIALITY, AND INVENTIONS AGREEMENT THIS Personal Services, Confidentiality, and Inventions Agreement (this “Agreement”) is between Avantor, Inc., presently headquartered at Radnor Corporate Center, Building One, Suite 200, 100 Matsonford Road, Radnor, PA 19087 (with its various affiliates, “Avantor” or the “Company”) and Emmanuel Ligner (“Executive” or “I”) who is employed by Avantor. Avantor’s sound business policy requires that its trade secrets, technical and non-technical know-how, business knowledge, plans, systems, business methods, business records and customer relations be protected and not utilized by any person or firm who competes or wants to compete with Avantor. The parties wish to evidence the terms of the employment relationship between them and particularly to set forth certain restrictions which shall apply to Executive in the event of termination of his/her employment with Avantor. In consideration of and as part of the terms of employment by Avantor, it is agreed as follows: 1. Compensation and Benefits. Executive shall be entitled to receive a salary, annual bonus, and other monetary compensation, which shall be established by Avantor at the inception of employment and may be periodically thereafter adjusted for increase. Executive shall also be entitled to participate in various Company employee benefit plans (for example, health insurance, retirement, and the like), in accordance with the participation requirements of said plans, and nothing contained herein shall confer benefit eligibility which is in any manner inconsistent with the terms of the benefit plans. 2. Executive’s General Obligations; Conflicts of Interest. During my employment with Avantor, I agree to devote substantially all my working time during normal business hours to Avantor. During my employment with Avantor, I agree to use my best efforts to perform the duties associated with my position and title with Avantor as Avantor may direct, not to engage in any other business or activity the nature of which shall be determined by Avantor to be competitive with Avantor, its suppliers or its customers and to comply with any Conflict-of-Interest Policy of Avantor. I acknowledge and agree that I will not serve on the Board of Directors of any other companies during my employment with Avantor without first obtaining prior written approval from Avantor’s Chief Executive Officer, or in absence of such, from the Board of Directors of Avantor in its discretion. I further agree to conform to all Company policies, practices, and procedures, to the extent such policies, practices and procedures have been provided to me in writing, as well as lawful directions of Avantor and/or its affiliates as to performance of services for Avantor, to the extent that the same are consistent with my position and title with Avantor. 3. No Existing Restrictive Agreements. Subject to Section 11, I represent that I am not a party to any contract limiting my present or future right to work for Avantor or to perform such activities as shall be required from time to time by Avantor. 4. Prior Employer Information. I agree that I will not use improperly or disclose any confidential or proprietary information or trade secrets of my former or current employers, principals, partners, co-venturers, customers, or suppliers, or the vendors or customers of such persons or entities, and Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
B-2 I will not violate any nondisclosure or proprietary rights agreement I might have signed in connection with any such employer, person or entity. 5. Non-Disclosure of Information. I recognize that, in the performance of my duties with Avantor, Confidential Information belonging to Avantor will come into my possession, including, without limitation, information regarding business methods, plans, systems, customer lists and customer relations, vendor lists and vendor relations, cost and pricing information, distribution and logistical information, and other information relating to the business of Avantor that is not known to the general public. I recognize that the business of Avantor is materially dependent upon the relationship between Avantor and its customers who are serviced by its associates and that Avantor has and will entrust me with Confidential Information that must remain the property of Avantor. As used in this Agreement, “Confidential Information” shall mean the trade secrets, technical and non-technical know-how, technical and business knowledge and information, plans and systems, business methods, customer lists and customer relations of Avantor, including but not limited to research, development, manufacturing, purchasing, accounting, data processing, engineering, marketing, merchandising, selling and invoicing, which information is acquired from or through Avantor during the course of my employment by Avantor. “Confidential Information” shall not include any information that is or becomes publicly known or that enters the public domain other than as a result of my breach of my obligations under this Agreement or any other agreement between me and Avantor. I agree that I will not at any time hereafter disclose Confidential Information to third parties or use Confidential Information for any purpose other than to further Avantor’s business, except as is required by law, any court of competent jurisdiction or any governmental agency or authority or recognized subpoena power. Notwithstanding the above, nothing in this Agreement shall prohibit or impede, or is intended to prohibit or impede, Executive from communicating, cooperating, participating in an investigation, or filing a complaint with any U.S. Federal, State or local governmental or law enforcement branch, agency or entity (collectively, a “Governmental Entity”) with respect to possible violations of any U.S. Federal, State or local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation, provided that in each case such communications and disclosures are consistent with applicable law. No provision in this Agreement prohibits Executive disclosing this Agreement to any Governmental Entity, and Executive may do so without disclosure to Avantor. Avantor may not retaliate against Executive for any of these activities, and nothing in this Agreement would require Executive to waive any monetary award or other payment that they might become entitled to from any Governmental Entity. Nothing contained in this Agreement prohibits or prevents Executive from, or places limitations or restrictions on Executive or is intended to prohibit or prevent Executive from, or place limitations or restrictions on Executive: (i) filing a charge with or participating, testifying or assisting in any investigation, hearing, whistleblowing proceeding or other proceeding before any government agency (e.g., Equal Employment Opportunity Commission (“EEOC”), National Labor Relations Board, the Securities and Exchange Commission (“SEC”)), including communicating directly with the SEC staff about possible securities law violations; (ii) making truthful statements or disclosures about alleged unlawful employment practices, retaliation, wage and hour violations or workplace discrimination, harassment, sexual harassment or assault, or any other law that is enforced by the EEOC or similar state agency; or (iii) making any disclosure or statement that an employer may not contractually Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
B-3 prohibit an employee from making under applicable law, including under Section 7 of the National Labor Relations Act or any other applicable state law. I understand and acknowledge that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in confidence to a Federal, State, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. I understand and acknowledge further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Except as provided in this paragraph or under applicable law, under no circumstance am I authorized to disclose any information covered by Avantor’s attorney-client privilege or attorney work product, or trade secrets, without prior written consent of Avantor. 6. Assignment of Inventions. I will make prompt and full disclosure to Avantor, will hold in trust for the sole benefit of Avantor, and will assign, exclusively to Avantor, all my right, title, and interest in and to any and all inventions, discoveries, designs, developments, improvements, copyrightable material, and trade secrets (collectively herein “Inventions”) that I, solely or jointly, may conceive, develop, or reduce to practice during the period of time I am in the employ of Avantor. I hereby waive and quitclaim to Avantor any and all claims of any nature whatsoever that I now or hereafter may have for infringement of any patent resulting from any patent applications for any Inventions so assigned to Avantor. My obligation to assign shall not apply to any Inventions about which I can prove that: (a) it was developed entirely on my own time; and (b) no equipment, supplies, facility, services, or trade secret information of Avantor were used in its development; and (c) it does not relate (i) directly to the business of Avantor or (ii) to the actual or demonstrably anticipated research or development of Avantor; and (d) it does not result from any work performed by me for Avantor. 7. Excluded and Licensed Inventions. I have attached hereto a list describing all Inventions belonging to me and made by me prior to my employment with Avantor that I wish to have excluded from this Agreement. If no such list is attached, I represent that there are no such Inventions. If in the course of my employment at Avantor, I incorporate into a Company product, process, or machine, an Invention owned by me or in which I have an interest, Avantor is hereby granted and shall have an exclusive royalty-free, irrevocable, worldwide license to make, have made, use, and sell that Invention without restriction as to the extent of my ownership or interest. 8. Application for Copyrights and Patents. I will execute any proper oath or verify any proper document in connection with carrying out the terms of this Agreement. If, because of my mental or physical condition or for any other reason whatsoever, Avantor is unable to secure my signature Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
B-4 to apply for or to pursue any application for any United States or foreign patent or copyright covering Inventions assigned to Avantor as stated above, I hereby irrevocably designate and appoint Avantor and its duly authorized officers and agents as my agent and attorney in fact, to act for me and in my behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of U.S. and foreign patents and copyrights thereon with the same legal force and effect as if executed by me. I will testify at Avantor’s request in any interference, litigation, or other legal proceeding that may arise during or after my employment and my reasonable expenses associated with said testimony will be paid by Avantor. 9. Third Party Information. I recognize that Avantor has received and will receive confidential or proprietary information from third parties subject to a duty on Avantor’s part to maintain the confidentiality of such information and to use it only for certain limited purposes. This information shall be deemed not to include any information that is or becomes publicly known or that enters the public domain other than as a result of my breach of my obligations under this Agreement or any other agreement between me and Avantor. During the term of my employment and thereafter I will not disclose nor use such information for the benefit of anyone other than Avantor or such third party, or in any manner inconsistent with any agreement between Avantor and such third party of which I am made aware, except as is required by law, any court of competent jurisdiction or any governmental agency or authority or recognized subpoena power. 10. Termination. I acknowledge that this Agreement shall not constitute a contract for employment for any specific period of time, and that either Avantor or I am free to terminate employment, “at will,” at any time, with or without cause. I agree that upon termination of my employment, for any or no reason, I will promptly return to Avantor all records of Confidential Information, including copies in my possession, and all other physical properties issued to me as an employee, in a reasonable state of function or repair. I will also so return any keys, pass cards, identification cards or other property belonging to Avantor. Returning all Company property is a condition of receiving severance benefits, if any. 11. Executive Assurances. I acknowledge that I am party to non-competition and non-solicitation obligations with a third party that may or may not be enforceable under applicable law. I have acted lawfully and appropriately in all respects with regard to the transition from employment at my former employer to my contemplated employment with Avantor and will comply with the terms of these non-competition and non-solicitation obligations without regard to whether or not they would be deemed enforceable if they were challenged. I have not and will not take, use, or in any way misappropriate any third party confidential or proprietary information. 12. Non-Waiver. The failure by Avantor to enforce any of the provisions hereof upon any default by me at a particular time or under certain circumstances shall not be treated as a permanent waiver of such provisions and shall not prevent subsequent enforcement of such provisions upon default by either party. 13. Irreparable Harm. I agree that any proven breach of this Agreement by me would cause irreparable harm to Avantor for which monetary damages could not adequately compensate. If Avantor proves a breach, irreparable harm shall be presumed, and I expressly waive any bonding Docusign Envelope ID: CD6B38EB-1D66-4597-9ED5-74890B0E5A16
B-5 requirement as a prerequisite to Avantor obtaining injunctive relief. Avantor can also seek damages and attorneys’ fees. 14. Assignability of This Agreement. The services contracted for between Avantor and me in this Agreement are personal, and therefore I may not assign this Agreement to any other person or entity. This Agreement may, however, be assigned by Avantor to a successor to the business of Avantor or to an affiliate of Avantor. 15. Severability. It is the intention of the parties that this Agreement shall be enforceable to the fullest extent permitted by local, State, and/or Federal law in the jurisdiction in which performance of this Agreement occurs, or in which performance of this Agreement is sought to be enforced. In the event that a court of competent jurisdiction determines that one or more provisions of this Agreement are not enforceable under the provisions of the jurisdiction in which performance occurs or enforcement is sought, such a determination shall not affect the enforceability of the remainder of this Agreement. 16. Other Agreements. This Agreement, together with the Letter Agreement, including the Annex attached thereto, dated April 10, 2026, between me and Avantor (the “Letter Agreement”), set forth the sole and entire agreement between the parties hereto, and supersedes and replaces any and all prior agreements, whether oral, written, or implied, entered into by me and Avantor, pertaining to my employment, the terms, conditions, and responsibilities thereof, and/or any other subject matter contained in this Agreement or the Letter Agreement. This Agreement and the Letter Agreement, including the Annex, shall be considered together as one agreement.

Furthermore, I understand that nothing in this Agreement shall prohibit or impede me, or is intended to prohibit or impede me, from communicating, cooperating, participating in an investigation or filing a complaint with any U.S. Federal, State or local governmental or law enforcement branch, agency or entity (collectively, a “Governmental Entity”) with respect to possible violations of any U.S. Federal, State or local law or regulation, or otherwise making disclosures to any Governmental Entity, in each case, that are protected under the whistleblower provisions of any such law or regulation, provided that in each case such communications and disclosures are consistent with applicable law. No provision in this General Release prohibits me disclosing this General Release to any Governmental Entity, and I may do so without disclosure to the Company. The Company may not retaliate against me for any of these activities, and nothing in this General Release would require me to waive any monetary award or other payment that I might become entitled to from any Governmental Entity. Nothing contained in this General Release prohibits or prevents me from, or places limitations or restrictions on me or is intended to prohibit or prevent me from, or place limitations or restrictions on me: (i) filing a charge with or participating, testifying or assisting in any investigation, hearing, whistleblowing proceeding or other proceeding before any government agency (e.g., Equal Employment Opportunity Commission (EEOC), National Labor Relations Board, the SEC), including communicating directly with the SEC staff about possible securities law violations; (ii) making truthful statements or disclosures about alleged unlawful employment practices, retaliation, wage and hour violations or workplace discrimination, harassment, sexual harassment or assault, or any other law that is enforced by the EEOC or similar state agency; or (iii) making any disclosure or statement that an employer may not contractually prohibit an employee from making under applicable law, including under Section 7 of the National Labor Relations Act or any other applicable state law. I understand and acknowledge that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that is made (i) in confidence to a Federal, State, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. I understand and acknowledge further that an individual who files a lawsuit for retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual files any document containing the trade secret under seal; and does not disclose the trade secret, except pursuant to court order. Except as provided in this paragraph or under applicable law, under no circumstance am I authorized to disclose any information covered by the Company’s attorney-client privilege or attorney work product, or trade secrets, without prior written consent of the Company. 9.
