Offer Letter, dated July 12, 2023 between the Company and R. Brent Jones

/s/ R. Brent Jones

Noncompetition, Non-solicitation and non-disparagement. You acknowledge that in the course of your employment with Avantor or any of its Subsidiaries or Affiliates you will become familiar with Avantor’s and its Subsidiaries’ and Affiliates’ trade secrets and with other confidential information concerning Avantor and such Subsidiaries and Affiliates and that your services will be of special, unique, and extraordinary value to Avantor and such Subsidiaries and Affiliates. Therefore, you agree that:

Noncompetition. During the Employment Period and for a period of twelve (12) months thereafter, you shall not directly or indirectly, anywhere in the world, own, manage, control, participate in, consult with, render services for or enter into employment with any business that competes with the business that Avantor or any of its Subsidiaries or Affiliates is engaged in at the time of your Separation (the “Business”). Nothing herein shall prohibit you from being a passive owner of not more than 2% of the outstanding stock of any class of a corporation that is publicly traded, so long as you have no active participation in the business of such corporation.

Non-solicitation. During the Employment Period and for a period of twenty-four (24) months thereafter, you shall not directly or indirectly (i) induce or attempt to induce any employee of Avantor or any of its Subsidiaries or Affiliates to leave the employ of Avantor or any such Subsidiary or Affiliate, or in any way interfere with the relationship between Avantor or any of its Subsidiaries or Affiliates and any employee thereof, (ii) hire any person who was an employee of Avantor or any of its Subsidiaries or Affiliates within one hundred eighty (180) days after your date of separation, (iii) induce or attempt to induce any customer, supplier, licensee or other business relation of Avantor or any of its Subsidiaries or Affiliates to cease doing business with Avantor or such Subsidiary or Affiliate or in any way interfere with the relationship between any such customer, supplier, licensee or business relation and Avantor or any of its Subsidiaries or Affiliates or (iv) directly or indirectly acquire or attempt to acquire an interest in any business relating to the Business and with which Avantor or any of its Subsidiaries or Affiliates has entertained discussions relating to the acquisition of such business by Avantor or any of its Subsidiaries or Affiliates in the twelve month (12) period immediately preceding your date of separation.

Non-disparagement. During the Employment Period and at any time thereafter, you shall not disparage Avantor or any of its Subsidiaries or Affiliates or any officer, employee, director, shareholder or member of Avantor Subsidiaries or Affiliates.

Enforcement. If, at the time of enforcement of Section 1(b)1 or 1(b)2, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree that the maximum duration, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum duration, scope and area permitted by law. Because your services are unique and because you have access to confidential information, the parties hereto agree that money damages would be an inadequate remedy for any breach of Section 1(b) of this Annex 1. Therefore, in the event a breach or threatened breach of Section 1(b) of this Annex 1, Avantor or any of its Subsidiaries or Affiliates or their successors or assigns may, in addition to other rights and remedies existing in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief in order to enforce, or prevent any violations of, the provisions hereof (without posting a bond or other security).

Additional Acknowledgments. You acknowledge that the provisions of Sections 1(b)1 and 1(b)2 are in consideration of: (i) employment with Avantor or its Subsidiaries or Affiliates and (ii) additional good and valuable consideration, including the payment of salary and bonus, as set forth in this Offer Letter. In addition, you agree and acknowledge that the restrictions contained in Sections 1(b)1 and 1(b)2 do not preclude you from earning a livelihood, nor do they unreasonably impose limitations on your ability to earn a living. In addition, you acknowledge (A) that the business of Avantor and its Subsidiaries and Affiliates will be conducted throughout the world, (B) notwithstanding the state of incorporation or principal office of Avantor or any of its Subsidiaries or Affiliates, or any of their respective executives or employees (including you), it is expected that Avantor and its Subsidiaries and Affiliates will have business activities and have valuable business relationships within its industry throughout the world, and (C) as part of your responsibilities, you will be traveling throughout the world in furtherance of Avantor’s or any of its Subsidiaries’ or Affiliates’ business and relationships. You agree and acknowledge that the potential harm to Avantor and any of its Subsidiaries and Affiliates of the non-enforcement of Sections 1(b)1 and 1(b)2 outweighs any potential harm to you of its enforcement by injunction or otherwise. You acknowledge that you have carefully read Section 1(b) of this Annex 1 and have given careful consideration to the restraints imposed upon you by Section 1(b) of this Annex 1 and are in full accord as to their necessity for the reasonable and proper protection of confidential and proprietary information of Avantor and any of its Subsidiaries and Affiliates now existing or to be developed in the future. You expressly acknowledge and agree that each and every restraint imposed by Section 1(b) of this Annex 1 is reasonable with respect to subject matter, time period and geographical area.

Definitions.

Miscellaneous.

Applicable Law. Section 1(b) of this Annex 1 shall be governed by, and construed in accordance with, the laws of the Commonwealth of Pennsylvania, without giving effect to any choice of law or conflict of law rules or provisions (whether of the Commonwealth of Pennsylvania or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the Commonwealth of Pennsylvania.

Consent to Jurisdiction. You hereby irrevocably submit to the nonexclusive jurisdiction of the United States District Court for the Eastern District of Pennsylvania and the state courts of the Commonwealth of Pennsylvania for the purposes of any suit, action or other proceeding arising out of Section 1(b) of this Annex 1 or any transaction contemplated hereby. You further agree that service of any process, summons, notice or document by certified or registered mail to your address as listed above or such other address or to the attention of such other person as you have specified by prior written notice to Avantor shall be effective service of process in any action, suit or proceeding in the Commonwealth of Pennsylvania with respect to any matters to which you have submitted to jurisdiction as set forth above in the immediately preceding sentence. You irrevocably and unconditionally waive any objection to the laying of venue of any action, suit or proceeding arising out of Section 1(b) of this Annex 1 or the transactions contemplated hereby in the United States District Court for the Eastern District of Pennsylvania or the state courts of the Commonwealth of Pennsylvania and hereby irrevocably and unconditionally waive and agree not to plead or claim in any such court that any such action, suit or proceeding brought in such court has been brought in an inconvenient forum.

Additional Agreements. The provisions of this Annex 1 are in addition to, and do not supersede, the provisions of the Personal Services, Confidentiality, and Inventions Agreement between you and Avantor.

MUTUAL WAIVER OF JURY TRIAL. BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, EACH PARTY TO THIS OFFER LETTER (INCLUDING AVANTOR) HEREBY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES HERETO, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE, ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS OFFER LETTERT, THE TRANSACTIONS CONTEMPLATED HEREBY AND/OR THE RELATIONSHIPS ESTABLISHED AMONG THE PARTIES HEREUNDER.

I understand that any payments or benefits paid or granted to me under the “Severance and Restrictive Covenants” annex of the Offer Letter represent, in part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive the payments and benefits specified in the “Severance and Restrictive Covenants” annex of the Offer Letter unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter or breach this General Release. I also acknowledge and represent that I have received all payments and benefits that I am entitled to receive (as of the date hereof) by virtue of any employment by the Company.

Except as provided in paragraph 4 below and except for the provisions of the Offer Letter which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts; or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies, practices or procedures of the Company; or any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively referred to herein as the “Claims”).

I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by paragraph 2 above.

I agree that this General Release does not waive or release any rights or claims that I may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release. I acknowledge and agree that my separation from employment with the Company in compliance with the terms of the Offer Letter shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967).

In signing this General Release, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of the Offer Letter. I further agree that in the event I should bring a Claim seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General Release shall serve as a complete defense to such Claims. I further agree that I am not aware of any pending claim of the type described in paragraph 2 as of the execution of this General Release.

I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct.

I agree that this General Release and the Offer Letter are confidential and agree not to disclose any information regarding the terms of this General Release or this Offer Letter, except to my immediate family and any tax, legal or other counsel I have consulted regarding the meaning or effect hereof or as required by law, and I will instruct each of the foregoing not to disclose the same to anyone. Notwithstanding anything herein to the contrary, each of the parties (and each affiliate and person acting on behalf of any such party) agree that each party (and each employee, representative, and other agent of such party) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of this transaction contemplated in the Offer Letter and all materials of any kind (including opinions or other tax analyses) that are provided to such party or such person relating to such tax treatment and tax structure, except to the extent necessary to comply with any applicable federal or state securities laws. This authorization is not intended to permit disclosure of any other information including (without limitation) (i) any portion of any materials to the extent not related to the tax treatment or tax structure of this transaction, (ii) the identities of participants or potential participants in the Offer Letter, (iii) any financial information (except to the extent such information is related to the tax treatment or tax structure of this transaction), or (iv) any other term or detail not relevant to the tax treatment or the tax structure of this transaction.

Any non-disclosure provision in this General Release does not prohibit or restrict me (or my attorney) from responding to any inquiry about this General Release or its underlying facts and circumstances by the Securities and Exchange Commission (SEC), the National Association of Securities Dealers, Inc. (NASD), any other self-regulatory organization or governmental entity. Furthermore, nothing in this Offer Letter shall prohibit or impede you from communicating, cooperating 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. You 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. You 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 are you 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.

Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Offer Letter after the date hereof.

Whenever possible, each provision of this General Release shall be interpreted in, such manner as to be effective and valid under applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.
