TRANSITION AGREEMENT
THIS TRANSITION AGREEMENT (this Agreement) is entered into as of the 30th day of May, 2025, by and between Cabot Corporation (Cabot or the Company) and Hobart C. Kalkstein (Kalkstein).
WHEREAS, in connection with his anticipated retirement from Cabot, Kalkstein has provided Cabot his resignation as Cabots Executive Vice President, effective June 15, 2025 (the Transition Date).

In addition, Kalksteins rights and obligations under Cabots benefit plans, including but not limited to the Deferred Compensation Plan, the Supplemental 401(k) Plan, and the Supplemental Cash Balance Plan shall be governed by the terms of such plans. During the Transition Period, Kalkstein will perform such duties as a full-time employee as may be assigned to him from time to time by the President and Chief Executive Officer of the Company or his designee, including but not limited to assisting with an orderly transition of his duties and responsibilities to the Senior Vice President, and President, Reinforcement Materials Segment, meeting with advisors and other constituents of the Company to facilitate this transition and providing advice to the Company based on his knowledge of the Company and its business. Kalkstein agrees to continue to devote his best professional efforts to the Company, and to abide by all Company policies and procedures as in effect from time to time. Provided that Kalkstein complies in full with his obligations hereunder, it is expected that the Retirement Date will be January 5, 2026; and unless Kalksteins employment with the Company terminates before such date, Kalkstein will retire from Cabot as of such date and no longer be an employee of the Company.
2. Consideration. In consideration of Kalksteins acceptance of this Agreement and subject to Kalkstein meeting in full his obligations hereunder, including his obligation to execute, without subsequently revoking, a post-employment general release and waiver of claims in the form attached hereto as Exhibit A (the Release of Claims) on or after the Retirement Date (and within the time period prescribed therein), and the non-competition and non-solicitation agreement in the form attached hereto as Exhibit B (the Non-Competition and Non-Solicitation Agreement), the Company agrees that the period of time during which Kalkstein shall be able to exercise any vested options to purchase Cabot common stock held by Kalkstein at the Retirement Date shall be the earlier of (i) 36 months from the Retirement Date and (ii) the original expiration date of such options. The table below sets forth the vested and unvested stock options Kalkstein holds as of the date hereof, and specifies the options scheduled to vest in accordance with their terms on November 8, 10 and 11, as applicable, the exercise periods of which vested options would be extended in accordance with the terms and conditions of this Agreement.

For the avoidance of doubt, this list shall be updated on the Retirement Date to reflect any option exercises from and after the date hereof through and including the Retirement Date.
If Kalkstein does not timely execute the Release of Claims, or if the Release of Claims does not become effective in accordance with its terms, or if Kalkstein does not timely execute the Non-Competition and Non-Solicitation Agreement, or if the Company terminates Kalksteins employment for Cause prior to January 5, 2026, the exercise period of Kalksteins vested options shall be as set forth in the relevant stock option award agreements. The extended exercise period of the vested options shall only become effective on the expiration of the seven-day period provided for in the Release of Claims, and only if the revocation rights contained therein are not timely exercised by Kalkstein, and following Mr. Kalksteins execution and delivery of the Non-Competition and Non-Solicitation Agreement.
Except as specifically modified by the preceding sentence, any such exercise of vested stock options by Kalkstein shall be in accordance with the terms of the Amended and Restated 2017 Long-Term Incentive Plan, as applicable, and the terms of the award agreements under which such stock options were granted.
Kalkstein understands and agrees that his rights and obligations with respect to any shares of stock, stock units or stock options granted to him by Cabot which are vested on or as of the Retirement Date shall be governed by the applicable equity plan under which they were granted and any agreements or other requirements applicable to those shares, stock units or options.

Award Grant Date | Time Based Stock Units | Performance Based Stock Units Granted | Stock Options | |||
Nov. 10, 2023 | 4,435 | 6,650 (consisting of 3,200 banked PSUs and 3,450 PSUs at target) | 5,616 options with exercise price of $74.40 | |||
Nov. 8, 2024 | 3,130 | 3,652 (grant at target) | 6,539 options with exercise price of $114.99 |
-2-
Kalkstein further understands and agrees that if Kalkstein terminates his employment with the Company for any reason prior to November 8, 10, or 11, 2025, as the case may be, or the Company terminates Kalksteins employment for Cause prior to any such date, the following long-term incentive grants, to the extent they remain unvested, will also be forfeited by Kalkstein on the date of such termination of employment with no consideration due to Kalkstein pursuant to the terms of such awards:
Award Grant Date | Time Based Stock Units | Performance Based Stock Units Granted | Stock Options | |||
Nov. 11, 2022 | 4,265 | 4,202 (consisting of 2,543 banked PSUs and 1,659 PSUs at target) | 5,594 options with exercise price of $73.84 | |||
Nov. 10, 2023 | 4,435 | 6,650 (consisting of 3,200 banked PSUs and 3,450 PSUs at target) | 9,828 options with exercise price of $74.40 | |||
Nov. 8, 2024 | 3,130 | 3,652 (grant at target) | 9,341 options with exercise price of $114.99 |
To the extent Kalkstein is in possession of any stock unit and/or stock option award certificates for any shares of stock and/or stock options granted to Kalkstein which will not be vested on or as of the Retirement Date, Kalkstein further agrees to return, no later than the Retirement Date, all such certificates in his possession.
3. Annual STI Bonus. Kalkstein shall be entitled to receive his 2025 short-term incentive bonus, based on Cabots actual performance for the full fiscal year and Kalksteins individual performance as assessed by Cabots President and Chief Executive Officer, and paid at the same time the 2025 STI bonuses are paid to participants in the STI program; provided however, if Kalkstein terminates his employment with the Company prior to September 30, 2025, or if the Company terminates Kalksteins employment for Cause prior to the payment of such bonus, Kalkstein shall not be entitled to such STI bonus.
For purposes of this Agreement, Cause, as determined by the Company in its good faith, reasonable judgment, shall mean only (i) Kalksteins material breach of this Agreement or any material written policy of the Company or its Affiliates, which material breach, if susceptible to cure, remains uncured fourteen (14) days after the Company has provided written notice to Kalkstein specifying in reasonable detail the nature of the alleged breach or (ii) Kalksteins commission of a felony or other crime involving moral turpitude. For purposes of this Agreement, Affiliates means all persons and entities directly or indirectly controlling, controlled by or under common control with the Company, where control may be by management authority, equity interest or otherwise.

4. Non-Competition, Non-Solicitation. To protect the Confidential Information (as defined below), customer goodwill and other legitimate business interests of Cabot (including, for purposes of this paragraph 4, Cabot, its Affiliates and its subsidiaries), Kalkstein agrees to execute and deliver to the Company the Non-competition and Non-solicitation Agreement (Exhibit B) on or after the Retirement Date. In exchange for the compensation and benefits provided to Kalkstein under this Agreement and as consideration for the promises Kalkstein makes to the Company under the Non-Competition and Non-Solicitation Agreement, and as provided in Kalksteins employment agreement with the Company dated January 7, 2005 (the Employee Agreement), during the period of non-competition and non-solicitation under the Non-Competition and Non-Solicitation Agreement, the Company shall continue to pay Kalkstein compensation in the form of bi-weekly payments at the rate of one-half of the base salary of wage being paid to Kalkstein at the Retirement Date for as long as such non-competition and non-solicitation obligations under the Non-Competition and Non-Solicitation Agreement remain in effect. This Agreement and the Non-Competition and Non-Solicitation Agreement supersede any post-employment non-competition and non-solicitation covenants set forth in the Employee Agreement.
5. Confidential Information.
(A) Kalkstein agrees that he will continue to keep confidential and protect Confidential Information, as defined herein, and that he will not, directly or indirectly, disclose it to others or use it for any purpose. As used in this Agreement, Confidential Information means:
(i) any and all information of Cabot (including, for purposes of this paragraph 5, Cabot, its Affiliates and its subsidiaries) of a confidential and/or proprietary nature, including, but not limited to: technology; inventions (whether or not patentable); trade secrets; samples; compositions; techniques and equipment; methods; manufacturing processes and processing conditions; engineering data; drawings; specifications; formulae; plant design and layout; products and product applications; development plans and new business opportunities; experimental work; commercial and developmental operations; the identities and requirements of customers and prospective customers; customer lists; suppliers and supplier lists; the identities of other individuals or third parties with whom Cabot has or with which Cabot is seeking to develop a business relationship and the nature and details of any such relationship or potential relationship; software and networks; business, marketing and any other plans and strategies; sales, pricing, raw materials and cost information; financial information; compensation, benefits and related incentives; and any other information relating to Cabot and its businesses beyond confidential and/or proprietary customer, supplier or business partner communications as set forth in (ii below to the extent that such information has not been published or is not publicly available; and,

-4-
Confidential Information does not include information that (a) is or becomes known publicly through no fault of Kalksteins; (b) Kalkstein has learned from a third party who Kalkstein believes in good faith and upon reasonable inquiry is entitled to disclose it; (c) is already known to Kalkstein before disclosure by the Company (provided that the information is not subject to another confidentiality agreement with or other contractual, legal or fiduciary obligation to the Company); or (d) is independently developed by Kalkstein without the use of or reference to the Confidential Information. Further, Confidential Information does not include information lawfully acquired, as a non-management employee, about wages, hours or terms and conditions of employment if used by Kalkstein for purposes protected by Section 7 of the National Labor Relations Act, such as joining or forming a union, engaging in collective bargaining, or engaging in other concerted activity for Kalksteins mutual aid or protection.
(B) Nothing in this Agreement prohibits Kalkstein from reporting an event that Kalkstein reasonably and in good faith believes is a violation of law to the relevant law-enforcement agency (such as the Securities and Exchange Commission, Equal Employment Opportunity Commission, or Department of Labor), or from cooperating in an investigation conducted by such a government agency. Kalkstein is hereby provided notice that under the 2016 Defend Trade Secrets Act (DTSA): (i) no individual (consultant, contractor or employee) will be held criminally or civilly liable under Federal or State trade secret law for the disclosure of a trade secret (as defined in the Economic Espionage Act) that: (a) is made in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and made solely for the purpose of reporting or investigating a suspected violation of law; or, (b) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal so that it is not made public; and, (ii) an individual (consultant, contractor or employee) who pursues a lawsuit for retaliation by an employer for reporting a suspected violation of the 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 as permitted by court order. Nothing in this Agreement or in any other Company agreement, policy, directive, or representation prohibits or impedes Kalkstein, or any employee or former employee of the Company, from communicating directly with the SEC under the protection of SEC Rule 21F-17. If Kalkstein has initiated communication with the SEC relating to a possible securities law or rule violation, nothing in this Agreement prohibits or impedes Kalksteins ability to continue to communicate directly with the SEC or requires Kalkstein to first seek consent, written or oral, from the Company before doing so. Further, nothing in this Agreement prohibits or impedes Kalkstein from testifying in any SEC proceeding or, if eligible under applicable law, interferes with Kalksteins right, if any, to receive an award from the government for information provided to the SEC.
6. Proprietary Rights. Kalkstein hereby agrees that all inventions, discoveries and improvements conceived or made by Kalkstein during his employment with Cabot (including, for purposes of this paragraph 6, Cabot, its Affiliates and its subsidiaries) that (i) relate to the business or activities of Cabot or (ii) were or are conceived or developed by Kalkstein during normal working hours or using Cabots facilities, belong to Cabot, whether or not reduced to writing or practice during Kalksteins employment with Cabot. Kalkstein hereby assigns to Cabot or its nominee all Kalksteins rights and interest in any
-5-
such inventions, discoveries and improvements and agrees to keep protected the interest of Cabot or its nominee in any such inventions, discoveries and improvements. Kalkstein is also assigning to Cabot or its nominee all copyrights and reproduction rights to any material prepared by Kalkstein during his employment with Cabot that (i) relate to the business activities of Cabot or (ii) were or are conceived or developed by Kalkstein during normal working hours or using Cabots facilities. To the extent that Kalkstein cannot assign and transfer any of the foregoing rights or interest, then Kalkstein hereby grants Cabot an irrevocable, worldwide, fully paid-up, royalty-free, exclusive license, with the right to sublicense through multiple tiers, to make, use, sell, improve, reproduce, distribute, perform, display, transmit, manipulate in any manner, create derivative works based upon, and otherwise exploit or utilize in any manner the aforesaid inventions, discoveries, improvements and materials. If within the twelve-month period following the Retirement Date, Kalkstein discloses to anyone or files a patent application with respect to any invention, discovery or improvement relating to any subject matter with which Kalksteins work for Cabot was concerned, such invention, discovery or improvement shall be presumed to have been made by Kalkstein during his employment with Cabot unless Kalkstein can provide clear and convincing evidence to the contrary.
7. Employment Agreement. Notwithstanding the foregoing, Kalkstein acknowledges that he continues to be bound by his obligations under the Employee Agreement to the extent such obligations are in addition to the obligations and matters set forth herein.
Except as otherwise stated herein, this Agreement does not modify or supersede any obligations that Kalkstein has to Cabot by law or otherwise.
8. Termination. This Agreement may be terminated by Cabot immediately for Cause. Notwithstanding anything in this Agreement to the contrary, the Company shall have the right to require that Kalkstein repay or forfeit, as applicable, his STI bonus or long-term incentive awards previously paid or provided to Kalkstein hereunder at any time if the Company determines, reasonably and in good faith, that Kalkstein has breached any of the terms and conditions of this Agreement or the Employee Agreement, or pursuant to the terms and conditions set forth in any applicable clawback policy of the Company, but any such termination of benefits shall not relieve Kalkstein of his obligations and undertakings under this Agreement. Other than with respect to any clawback, any Company determination made under this paragraph shall be subject to judicial review.
9. Acknowledgement, Severability. Kalkstein acknowledges that he has carefully read and considered all the terms and conditions of this Agreement, including the restraints imposed upon him pursuant to paragraphs 4, 5 and 6. Kalkstein understands and agrees that these restraints are necessary for the reasonable and proper protection of the legitimate business interests of Cabot (including, for purposes of this paragraph 9, Cabot, its Affiliates and its subsidiaries), and that a breach by Kalkstein of any one of these restraints would cause irreparable harm and damage to Cabot. Kalkstein further acknowledges that damages would not be an adequate remedy for a breach or threatened breach by Kalkstein of any one of the covenants referenced in paragraphs 4, 5 and 6 and under the Non-Competition and Non-Solicitation Agreement. Kalkstein therefore agrees that Cabot shall be entitled to the enforcement of this Agreement by injunction, specific performance or other equitable relief, without need of posting a bond and without prejudice to any other rights and remedies that Cabot may have under this Agreement or under applicable law. Kalkstein further agrees that in the event that any provision of this Agreement or under the Non-Competition and Non-Solicitation Agreement shall be determined by any court of competent jurisdiction to be unenforceable by reason of its being extended over too great a time, too large a geographic area or too great a range of activities, such provision shall be deemed to be
-6-
modified to permit its enforcement to the maximum extent permitted by law. In the event of any breach, or alleged or threatened breach, of this Agreement, Kalkstein hereby consents and submits to the jurisdiction of the federal and state courts in and of the Commonwealth of Massachusetts, and this Agreement shall be governed by and interpreted in accordance with the laws of the Commonwealth of Massachusetts, without regard to the conflict of laws principles thereof.
10. Reliance, Entire Agreement. Kalkstein hereby represents and acknowledges that in executing this Agreement, he does not rely and has not relied upon any representation or statement (other than the express terms of this Agreement) made by Cabot or by any agents, representatives or attorneys of Cabot with regard to the subject matter, basis or effect of this Agreement. This Agreement (including Exhibit A and Exhibit B) constitutes the entire agreement between Kalkstein and Cabot and replaces all prior and contemporaneous agreements, communications and understandings, whether written or oral, with respect to Kalksteins employment at Cabot and its termination and all related matters, except as otherwise specifically provided herein.
11. Amendment. This Agreement may not be modified, altered or changed except upon express written consent of both parties wherein specific reference is made to this Agreement.
12. Return of Company Property. In signing this Agreement, Kalkstein represents and warrants that, by the Retirement Date, Kalkstein will have returned to the Company any and all non-public documents, materials and information (whether in hardcopy, on electronic media or otherwise) related to Company business (whether present or otherwise) and all keys, access cards, credit cards, computer hardware and software, telephones and telephone-related equipment and all other property of the Company or any of its Affiliates in Kalksteins possession or control. Cabot may decide to allow Kalkstein to keep his computer and or phone should they have no residual useful value for Cabot and only if they are wiped clean of all Company information. Further, Kalkstein represents and warrants that he will not retain any copy of any non-public Company documents, materials or information (whether in hardcopy, on electronic media or otherwise). Recognizing that Kalksteins employment with the Company will end on the Retirement Date, Kalkstein agrees that he will not, for any purpose, attempt to access or use any Company computer or computer network or system, including without limitation its electronic mail system after the Retirement Date. Further, Kalkstein acknowledges that he will disclose to the Company all passwords necessary or desirable to enable the Company to access all information which he has password-protected on any of its computer equipment or on its computer network or system.
