 EXHIBIT 10.1 

Cabot Corporation 

Summary of Non-Employee Directors Compensation 

The cash compensation payable to Cabot’s non-employee directors consists of separate annual cash retainers for serving on the Board and on each
Committee on which a director serves, and an annual cash retainer for serving as non-Executive Chairman of the Board or as a Committee chair. Following a review of the competitiveness of Cabot’s director compensation practices, on July 8,
2010, upon the recommendation of the Governance and Nominating Committee of the Board of Directors, Cabot’s Board of Directors approved an increase, effective July 1, 2010, from $31,000 to $65,000 in the annual cash retainer payable to
each non-employee Director for his or her service on the Board. No other changes were made in the cash compensation package. With this change, the annual cash compensation payable to Cabot’s non-employees consists of the following payments:

  

	 	•	 	 An annual retainer of $65,000 for service on the Board of Directors 

 

	 	•	 	 An annual retainer of $21,000 for service on the Audit Committee 

 

	 	•	 	 An annual retainer of $7,000 for service on each of the Compensation, Safety, Health and Environmental Affairs, or Governance and Nominating Committees

  

	 	•	 	 An annual retainer of $110,000 for service as Non-Executive Chairman of the Board of Directors 

 

	 	•	 	 An annual retainer of $40,000 for service as Chair of the Audit Committee 

 

	 	•	 	 An annual retainer of $10,000 for service as Chair of the Compensation, Safety, Health and Environmental Affairs, or Governance and Nominating
Committees 

 In addition to the cash compensation described above, under Cabot’s Non-Employee Directors’ Stock
Compensation Plan (the “Directors’ Stock Plan”), each non-employee director receives shares of Cabot common stock as a portion of his or her compensation for services performed in the calendar year. On July 7, 2010, the
Governance and Nominating Committee of the Board of Directors authorized, for calendar year 2011, the issuance to each non-employee director of the number of whole shares of Cabot common stock having, on the date of grant, a market value as close as
possible to $75,000 for services to be performed in the calendar year.Severance Plan and Summary Plan Description

GENERAL SEVERANCE BENEFIT 

2.1 Severance Benefit. Except as otherwise provided in this Section 2.1 or as set forth in an individual employment
agreement or change in control agreement with an Eligible Employee that specifically supersedes such Eligible Employee’s rights to benefits pursuant to this Plan, the Plan supersedes all prior practices, policies, procedures and plans relating

 ARTICLE III 

SEVERANCE BENEFITS 

3.1 Cash Severance Benefits. 

(a) Tenured Employees. An Eligible Employee that has been employed by the Company or an affiliate of the Company for a
continuous period of two or more years following the Eligible Employee’s initial hire date (a “Tenured” Employee) shall be eligible to receive a severance payment from the Company upon the Eligible Employee’s
incurrence of a Qualifying Termination Event as follows: 
 (i) Tenured Tier 3 Employees. In the event a Tenured Tier 3
Employee incurs a Qualifying Termination Event, then the Tenured Tier 3 Employee will be entitled to receive a severance payment equal to 75% of the Eligible Employee’s Annual Compensation. For example, if the Tenured Tier 3 Employee’s
Annual Base Salary is $100,000, and his Pro-Rata Annual Bonus was $25,000, the severance payment would equal $93,750 (.75 x ($100,000 + $25,000)). 

(ii) Tenured Tier 2 Employees. In the event a Tenured Tier 2 Employee incurs a Qualifying Termination Event, then the Tenured
Tier 2 Employee will be entitled to receive a severance payment equal to equal to 150% of the Eligible Employee’s Annual Compensation. For example, if Tenured Tier 2 Employee’s Annual Base Salary is $100,000, and his Pro-Rata Annual Bonus
was $25,000, the severance payment would equal $187,500 (1.5 x ($100,000 + $25,000)). 
 (iii) Tenured Tier 1 Employees.
In the event a Tenured Tier 1 Employee incurs a Qualifying Termination Event, then the Tenured Tier 1 Employee will be entitled to receive a severance payment equal to equal to 200% of the Eligible Employee’s Annual Compensation. For example,
if Tenured Tier 1 Employee’s Annual Base Salary is $100,000, and his Pro-Rata Annual Bonus was $25,000, the severance payment would equal $250,000 (2.0 x ($100,000 + $25,000)). 

(b) New Employees. An Eligible Employee that has been employed by the Company or an affiliate of the Company for a
continuous period of less than two years following the Eligible Employee’s initial hire date (a “New” Employee) will be eligible to receive a pro-rata severance payment from the Company upon the New Employee’s
incurrence of a Qualifying Termination Event. The pro-rata severance payment shall be calculated based upon the payments described in Section 3.1(a)(i) – (iii) above, multiplied by (x/y). For purposes of this Section 3.1(b),
“x” shall mean the number of days the New Employee has been employed by the Company or an affiliate of the Company, and “y” shall mean 730. For example, an Eligible Employee hired on January 1, 2010 incurs a Qualifying
Termination Event on September 30, 2011. If the New Employee is also a Tier 3 Employee with the same Annual Compensation as the Tier 3 Employee in Section 3.1(a)(i), and has been employed by the Company continuously from his hire date to
his Termination of Employment, the New Employee’s pro-rata severance payment would be calculated as follows: 
 (.75 x
($100,000 + $25,000)) x (638/730) = $81,935 
  

 5 

 (c) Intermittent Employees. An Eligible Employee that has provided services as
an Eligible Employee to the Company or an affiliate of the Company for intermittent periods of time, regardless of the aggregate time period the Eligible Employee has provided services to the Company or an affiliate of the Company (an
“Intermittent” Employee), will be eligible to receive a pro-rata severance payment from the Company upon the Intermittent Employee’s incurrence of a Qualifying Termination Event. The pro-rata severance payment shall be
calculated based upon the payments described in Section 3.1(a)(i) – (iii) above, multiplied by (x/y). For purposes of this Section 3.1(c), “x” shall be the number of days the Intermittent Employee has been employed by
the Company or an affiliate of the Company during any continuous two year period for which “x” would be deemed to be the highest, and “y” shall be 730. For example, an Intermittent Employee has been employed by the Company during
the following dates (i) January 1, 2010 to June 30, 2010; (ii) January 1, 2011 to November 30, 2012; and (iii) July 1, 2013 to September 30, 2014. The Intermittent Employee incurs a Qualifying Termination
Event on September 30, 2014. If the Intermittent Employee is also a Tier 3 Employee with the same Annual Compensation as the Tier 3 Employee in Section 3.1(a)(i), the Intermittent Employee’s pro-rata severance payment would be
calculated as follows: 
 (.75 x ($100,000 + $25,000)) x (699/730) = $89,769 

The number for “x” in this example was taken from the period of time the Eligible Employee was employed between January 1, 2011 and
November 30, 2012, as it was the largest number of days which were worked in any continuous two year period. 
 (d)
Termination of Employment without a Qualifying Termination Event. In the event that an Eligible Employee incurs a Termination of Employment that is not a Qualifying Termination Event, the Eligible Employee shall not be entitled to any
cash severance benefits pursuant to this Plan. 
 (e) Pro-Rata Annual Bonus. In addition to the payment to be made
under Section 3.1(a)-(d) above, an Eligible Employee, upon an incurrence of a Qualifying Termination Event, shall receive the following additional payment equal to: 

(i) Tenured Employee. For a Tenured Employee, such Tenured Employee shall receive his or her Pro-Rata Annual Bonus attributable
to the year in which the Qualifying Termination Event occurs; 
 (ii) New Employee. For a New Employee, such New
Employee shall receive an amount equal to his or her Pro-Rata Annual Bonus attributable to the year in which the Qualifying Termination Event occurs multiplied by (x/y) where, for purposes of this subsection (ii), “x” shall mean the number
of days the New Employee has been employed by the Company or an affiliate of the Company, and “y” shall mean 730; and 
  

 6 

 (iii) Intermittent Employees. For Intermittent Employees, such Intermittent Employee
shall receive an amount equal to Pro-Rata Annual Bonus attributable to the year in which the Qualifying Termination Event occurs multiplied by (x/y) where, for purposes of this subsection (iii), “x” shall be the number of days the
Intermittent Employee has been employed by the Company or an affiliate of the Company during any continuous two year period for which “x” would be deemed to be the highest, and “y” shall be 730. 

3.2 Accrued or Vested Benefits. In the event that an Eligible Employee’s employment with the Company or its successor
is terminated due to the occurrence of a Qualifying Termination Event, the Company shall pay to such Eligible Employee a lump sum cash amount equal to the sum of (A) the Eligible Employee’s accrued and unpaid salary as of his date of
termination plus (B) reimbursement for all expenses reasonably and necessarily incurred by the Eligible Employee (in accordance with Company policy) prior to termination in connection with the business of the Company plus
(C) any accrued vacation pay, to the extent not theretofore paid plus (D) any amounts vested, but unpaid, prior to termination for annual cash performance awards (or equivalent award for annual performance) plus
(E) payments for any other benefits which have vested or accrued prior to such Eligible Employee’s Termination of Employment. This amount shall be paid within ten (10) days of the Eligible Employee’s Termination of Employment, or
pursuant to the time set forth in the applicable plan document from which any vested benefits shall be paid, as applicable. 

3.3 Form and Timing of Cash Severance Benefit. Subject to the restrictions set forth in Section 3.6 below, cash
severance benefits payable pursuant to Section 3.1 shall be paid on a once-monthly basis in substantially equal increments. The first installment payment shall be made on the 60th day following the Eligible Employee’s Termination of
Employment, and thereafter monthly payments will continue in accordance with the Company’s normal payroll practices until the completion of the Eligible Employee’s applicable Severance Period. In the event that any monthly severance
payments that should have been made to the Eligible Employee, but, due to the delay in payments pursuant to the Release Period (as defined in Section 3.6 below), were not paid to the Eligible Employee, such payments will be aggregated, without
interest, and payable in a lump sum along with the first installment payment scheduled for the 60th day following the Eligible Employee’s Termination of Employment; provided, however, that no payments due to any Eligible Employee under this
Plan shall be made following the 24-month period immediately following the Eligible Employee’s Termination of Employment. 

3.4 Continued Medical Benefits. In the event an Eligible Employee incurs a Qualifying Termination Event, the Company shall
reimburse the Eligible Employee an amount equal to the aggregate applicable monthly premiums required for the Eligible Employee (and the Eligible Employee’s dependents, if applicable) to continue Eligible Employee’s group health care
coverage for a period of time equal to the applicable Severance Period for the Eligible Employee, under the applicable provisions of the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), provided that Eligible
Employee elects to continue and remains eligible for these benefits under COBRA. Subject to the restrictions set forth in Section 3.6 below, the Company shall pay the Eligible Employee the amount required under this Section 3.4 on a
monthly basis beginning on the 60th day following the Eligible Employee’s Termination of Employment. In the event that any payments that should have been made to the Eligible Employee, but, due to the delay in payments pursuant to the Release
Period (as defined in Section 3.6 below), were not paid to the Eligible Employee, such payments will be aggregated, without interest, and payable in a lump sum along with the first monthly payment scheduled for the 60th day following the
Eligible Employee’s Termination of Employment 
  

 7 

 3.5 Awards Under Equity Plans. Unless specifically excluded from the Plan
under the award agreement, notwithstanding anything to the contrary in any applicable award agreement under the Equity Plans or other plan or arrangement maintained or sponsored by the Company, in the event that an Eligible Employee incurs a
Qualifying Termination Event, the Eligible Employee’s outstanding awards under the Equity Plans or other plan or arrangement maintained or sponsored by the Company will receive the following treatment: 

(a) All unvested stock option awards granted pursuant to the 1995 Plan, the 2004 Plan or the 2010 Plan shall be immediately forfeited
without further payment to the Eligible Employee. 
 (b) All vested but unexercised stock option awards granted pursuant to the
1995 Plan shall remain exercisable by the Eligible Employee for a period of three months following the Eligible Employee’s Termination of Employment. 

(c) All vested but unexercised stock option awards granted pursuant to the 2004 Plan or the 2010 Plan shall remain exercisable by the
Eligible Employee for a period of six months following the Eligible Employee’s Termination of Employment. 
 (d) All
unvested restricted stock awards granted pursuant to the Equity Plans shall be immediately forfeited without further payment to the Eligible Employee. 

(e) Any unvested annual performance awards granted pursuant to the Equity Plans shall be immediately forfeited without further payment to
the Eligible Employee. 
 (f) All other awards under the Equity Plans shall be immediately forfeited without further payment to
the Eligible Employee 
 3.6 Release and Other Restrictions. 

(a) Agreements. Notwithstanding any other provision in the Plan to the contrary, as consideration for receiving cash
severance benefits under the Plan pursuant to Sections 3.1 and 3.4, each Eligible Employee who is otherwise entitled to receive such benefits must execute a release, along with certain protection of confidential information requirements,
non-competition and non-solicitation restrictions as reasonably required by the Plan Administrator, in the form and pursuant to the procedures reasonably established by the Plan Administrator. For purposes of this Plan, the general form of release
and the restrictive covenants (protection of confidential information, non-competition and non-solicitation) to be executed by an Eligible Employee prior to receiving any cash severance benefits pursuant to this Plan shall be substantially in the
form as the provisions attached hereto as Exhibit D (the “Release Agreement”). Cash severance benefits shall be conditioned upon the execution, non-revocation, and delivery of a Release Agreement by Eligible Employee
within 60 days of the date of Eligible Employee’s Termination of Employment (the “Release Period”). Notwithstanding the form and timing of payments noted within the Sections 3.1 or 3.4 above, in the event that the
Company has not received a properly executed Release Agreement by the Eligible Employee during the Release Period, or the revocation period during which Eligible Employee is entitled to revoke such Release Agreement has not expired during such
Release Period, the Eligible Employee shall not be entitled to receive any payments or benefits pursuant to this Plan. The Company shall deliver the final form of the Release Agreement for Eligible Employee’s consideration within the three day
period immediately following the Eligible Employee’s Termination of Employment in order to ensure that the Eligible Employee has adequate time to complete each of the Eligible Employee’s requirements set forth herein. 

 

 8 

 (b) Violation of Agreements. If an Eligible Employee fails to properly execute
and not revoke the Release Agreement during the Release Period, or the Eligible Employee chooses not to sign such an agreement for any reason, the Eligible Employee shall not be entitled to cash severance benefits under Sections 3.1 and 3.4 of the
Plan. If at any time during the Eligible Employee’s Severance Period, the Plan Administrator determines that the Eligible Employee is in violation of his Release Agreement, all benefit or payment obligations of the Company under Sections 3.1
and 3.4 of the Plan shall immediately cease. The Plan Administrator, in its sole discretion, shall determine whether the Eligible Employee’s applicable violation of the Release Agreement may be cured, and the severance benefits reinstated.

 3.7 Section 409A of the Code. Notwithstanding any provision of this Plan to the contrary, if the Eligible
Employee is considered a “specified employee” upon his Termination from Employment under such procedures as established by the Company in accordance with the Nonqualified Deferred Compensation Rules, any portion of a cash or benefit
distribution made upon such a Termination from Employment that would cause the acceleration of, or an addition to, any taxes pursuant to the Nonqualified Deferred Compensation Rules may not commence earlier than six months after the date of such
Termination from Employment; any payments or benefits that would be exempt from the Nonqualified Deferred Compensation Rules shall be paid in accordance with the original schedules noted in this Article III above. Therefore, in the event this
Section 3.6 is applicable to the Eligible Employee, any distribution which would cause the acceleration of, or an addition to, any taxes pursuant to the Nonqualified Deferred Compensation Rules that would otherwise have been paid to the
Eligible Employee within the first six months following the Termination from Employment shall be accumulated and paid to the Eligible Employee in a lump sum on the first day of the seventh month following the Termination from Employment. All
subsequent distributions, if any, shall be paid in the manner otherwise specified herein. 
 ARTICLE IV 

GENERAL PROVISIONS 

4.1 Funding and Cost of Plan. The severance benefits provided herein shall be unfunded and shall be provided from the
Company’s general assets. The cost of providing severance benefits under the Plan shall be borne by the Company.

denial of severance benefit claims, and review of claims denials. The Plan Administrator has absolute discretion in the exercise of its powers and responsibilities. To the extent the Plan Administrator delegates its responsibilities and powers as
Plan Administrator, the Plan Administrator shall, without limiting any rights that the delegate may have under the Company’s charter or bylaws, applicable law or otherwise, indemnify and hold harmless each such delegate (and any other
individual acting on such delegate’s behalf) against any and all expenses and liabilities arising out of such person’s administrative functions or fiduciary responsibilities, excepting only expenses and liabilities arising out of the
delegate’s own gross negligence or willful misconduct; expenses against which such delegate shall be indemnified hereunder include without limitation the amounts of any settlement, judgment, attorneys’ fees, costs of court, and any other
related charges reasonably incurred in connection with a claim, proceeding, settlement, or other action under the Plan. 
 4.4

May 4, 2010 and terminate December 31, 2010. 
 4.5 Amendment and Termination. Notwithstanding any
provision of any other communication, either oral or written, made by the Company, by the Plan Administrator, or by any other individual or entity to Eligible Employees, to any service provider, or to any other individual or entity, the Plan
Administrator reserves the absolute and unconditional right to amend the Plan from time to time on behalf of the Company, including the right to reduce or eliminate benefits provided pursuant to the provisions of the Plan as such provisions
currently exist or may hereafter exist, and the right to amend prospectively or retroactively; provided, however, the Plan may not be amended to decrease benefits payable or to be provided to an Eligible Employee following that Eligible
Employee’s Qualifying Termination Event. All amendments to the Plan shall be in writing and executed by a duly authorized representative of the Plan Administrator, and any oral statements or representations made by the Company, by the Plan
Administrator, or any other individual or entity that alter, modify, amend, or are inconsistent with the written terms of the Plan shall be invalid and unenforceable and may not be relied upon by any Eligible Employee, Employee, beneficiary, service
provider, or other individual or entity. 
 4.6 Successors. Any successor to the Company shall assume the
Company’s obligations under the Plan. The failure of any successor to assume the Plan or any termination or amendment of the Plan that does not comply with the provisions of Section 4.5 shall be deemed to be a Qualifying Termination Event
for all Eligible Employees. 
 4.7 Claims Procedure and Review. Claims for severance benefits under the Plan shall
be made to the Plan Administrator. If a claim for severance benefits is wholly or partially denied, the Plan Administrator shall, within a reasonable period of time but no later than 90 days after receipt of the claim (or 180 days after receipt of
the claim if special circumstances require an extension of time for processing the claim), notify the claimant of the denial. Such notice shall (a) be in writing, (b) be written in a manner calculated to be understood by the claimant,
(c) contain the specific reason or reasons for denial of the claim, (d) refer specifically to the pertinent Plan provisions upon which the denial is based, (e) describe any additional material or information necessary for the claimant
to perfect the claim (and explain why such material or information is necessary), and (f) describe the Plan’s claim review procedures and time limits applicable to such procedures, including a statement of the claimant’s right to
bring a civil action under section 502(a) of the ERISA, following an adverse benefit determination on review. Within 60 days of the receipt by the claimant of this notice, the claimant may file a written appeal with the Plan Administrator. In
connection with the appeal, the claimant may review Plan documents and may submit written issues and comments. The Plan Administrator shall deliver to the claimant a written decision on the appeal promptly, but not later than 60 days after the
receipt of the claimant’s appeal (or 120 days after receipt of the claimant’s appeal if there are special circumstances which require an extension of time for processing). Such decision shall (i) be in writing, (ii) be written in

 4.8 Not Contract of Employment. The adoption and maintenance of the Plan shall
not be deemed to be a contract of employment between the Company and any person, to be consideration for the employment of any person, or to have any impact whatsoever on the at-will employment relationship between the Company and the Eligible
Employees. Nothing in the Plan shall be deemed to give any person the right to be retained in the employ of the Company or to restrict the right of the Company to discharge any person at any time. Nothing in the Plan shall be deemed to give the
Company the right to require any person to remain in the employ of the Company or to restrict any person’s right to terminate employment at any time. 

4.9 Governing Law. This Plan shall be interpreted under the laws of the State of Delaware except to the extent preempted by
federal law. 
 4.10 Gender; Number. Wherever appropriate herein, the masculine, neuter, and feminine genders
shall be deemed to include each other, and the plural shall be deemed to include the singular and vice versa. 
 4.11
Offer to Rehire. Notwithstanding any Plan provisions to the contrary, any installment severance benefits payable to a person under Sections 3.1 and 3.4 of the Plan shall terminate if and when the person is offered re-employment with
the Company, or its subsidiaries or affiliates and: 
 (a) Eligible Employee’s authority, duties or responsibilities with
the Company (or any affiliate of Company or any successor thereof) are materially consistent with Eligible Employee’s prior position with the Company (or any affiliate of Company or any successor thereof) and the nature or status of Eligible
Employee’s responsibilities or the conditions of Eligible Employee’s employment are materially consistent with those of the Eligible Employee in effect immediately prior to the Eligible Employee’s Termination of Employment;

  

 11 

 (b) Eligible Employee’s annualized cash and benefits compensation opportunity, which
shall include Eligible Employee’s base compensation, Eligible Employee’s annual target bonus opportunity and Eligible Employee’s aggregate employee benefits, shall be materially the same as in effect immediately prior to Eligible
Employee’s Termination of Employment; and 
 (c) the Eligible Employee’s office or location which would not increase
his daily commute distance by more than 50 miles (one-way) from the location at which the Eligible Employee normally performed Eligible Employee’s services immediately prior to the Termination of Employment, except for travel reasonably
required in the performance of the Eligible Employee’s responsibilities or the Eligible Employee being required to travel away from the his office in the course of discharging the his responsibilities or duties hereunder significantly more (in
terms of either consecutive days or aggregate days in any calendar year) than was required of the Eligible Employee prior to the Termination of Employment. 

4.12 Overpayment. If, due to mistake or any other reason, a person receives severance benefits under this Plan in excess of
what the Plan provides, that person shall repay the overpayment to the Company in a lump sum within 30 days of notice of the amount of overpayment. If that person fails to so repay the overpayment, then without limiting any other remedies available
to the Company, the Company may deduct the amount of the overpayment from any other amounts which become payable to that person under the Plan or otherwise. 

4.13 Headings. The headings of the Articles and Sections are included solely for convenience. If the headings and the text
of the Plan conflict, the text shall control. All references to Articles and Sections are to the Plan unless otherwise indicated. 

4.14 Severability. If any provision of the Plan is held to be illegal or invalid for any reason, that holding shall not
affect the remaining provisions of the Plan. Instead, the Plan shall be construed and enforced as if such illegal or invalid provision had not been contained herein. 

4.15 Mitigation. An Eligible Employee will not be required to mitigate the amount of any payment required hereunder.

 4.16 Withholding. The Company may withhold from any amounts payable under the Plan any federal, state or local
taxes as the Company is required to withhold pursuant to any law or government regulation or ruling. 
 4.17 Benefits are
Not Insured. The Plan is a severance plan. The Pension Benefits Guaranty Corporation under Title IV of ERISA does not insure benefits under this Plan. 
  

 12 

 4.18 ERISA Rights. 

As a participant in the Plan, Eligible Employees are entitled to certain rights and protections under ERISA, which provides that all Plan
participants shall be entitled to: 
 (a) Examine without charge, at the Plan Administrator’s office and at other specified
locations such as worksites, all Plan documents, and copies of all documents filed by the Plan with the U.S. Department of Labor, such as detailed annual reports. 

(b) Obtain copies of all Plan documents and other Plan information upon written request to the Plan Administrator. The Plan Administrator
may make a reasonable charge for the copies. 
 (c) To the extent applicable, receive a summary of the Plan’s annual
financial report. The Plan Administrator is required by law to furnish each participant with a copy of this summary annual report. 

In addition to creating rights for Plan participants, ERISA imposes obligations upon the people who are responsible for the operation of
employee benefit plans. The people who operate the Plan, called “fiduciaries” of the Plan, have a duty to do so prudently and in the interest of Eligible Employees and beneficiaries. No one, including the Company, may fire an Eligible
Employee or otherwise discriminate against the Eligible Employee in any way to prevent the Eligible Employee from obtaining benefits or exercising his or her rights under ERISA. 

If a claim for a severance benefit is denied in whole or in part, an Eligible Employee has the right to know why this was done, to obtain
copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules. 

Under ERISA, there are steps an Eligible Employee can take to enforce the above rights. For instance, if an Eligible Employee requests
materials from the Plan Administrator and does not receive them within 30 days, the Eligible Employee may file suit in a federal court. In such a case, the court may require the Plan Administrator to provide the materials and pay the Eligible
Employee up to $110 a day until the Eligible Employee receives the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. If an Eligible Employee’s claim for severance benefits is denied
or ignored, in whole or in part, the Eligible Employee may file suit in a state or federal court. If an Eligible Employee is discriminated against for asserting his or her rights, the Eligible Employee may seek assistance from the U.S. Department of
Labor, or file suit in a federal court. The court will decide who should pay court costs and legal fees. If the Eligible Employee is successful, the court may order the person sued by the Eligible Employee to pay the costs and fees. If the Eligible
Employee loses, the court may order the Eligible Employee to pay the costs and fees (for example, if it finds that the Eligible Employee’s claim is frivolous). 

If an Eligible Employee has any questions about this Plan, the Eligible Employee should contact the Plan Administrator. If an Eligible
Employee has any questions about this statement or about his or her rights under ERISA, or if an Eligible Employee needs assistance in obtaining documents from the Plan Administrator, he or she should contact the nearest office of the Employee
Benefits Security Administration, U.S. Department of Labor, listed in the telephone directory or the Division of Technical Assistance and Inquiries, Employee Benefits Security Administration, U.S. Department of Labor, 200 Constitution Avenue N.W.,
Washington D.C. 20210. An Eligible Employee may also obtain certain publications about his or her rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

against the Released Parties. Employee further acknowledges that Employee has carefully read this Release and understands its final and binding effect, has had a reasonable amount of time to consider it, has been advised to seek, and has had the

Agreement (or their successors)(“MetroPCS Competitors”); provided, however, that Employee may consult with, or provide services or assistance to, an entity or person set forth on Schedule 1 to this Agreement (or their
successors) other than as an employee, officer, or director of such entity or person so long as such services or assistance does not involve, and will not result in, the use or disclosure of Confidential Information. 

 

 D-2 

 (b) If Employee materially breaches Section 5(a), the parties agree that it would be

shall be entitled to cease providing any future cash severance benefits pursuant to Sections 3.1 and 3.4 of the Plan. 
 (c)
Employee may terminate his obligations under Section 5(a) at any time upon prior written notice to the Company and the Company shall be entitled to immediately cease providing the cash severance benefits to Employee pursuant to Sections 3.1 and

	6.	Certain Covenants by the Employee 

(a) Protection of Confidential Information. The Employee acknowledges that in the course of his employment with the Company,
the Employee has obtained confidential, proprietary and/or trade secret information of the Company, relating to, among other things, (i) programs, strategies, information or materials related to the business, services, manner of operation and
activities of the Company, (ii) customers, suppliers, dealers, distributors, clients or prospects of the Company, (iii) computer hardware or software used in the course of the Company business, (iv) marketing strategies or other
activities of the Company from or on behalf of any of its clients, (v) business plans, business strategies, and employee names and information, (vi) trade secrets, patent applications, and other intellectual property of the Company, and
(vii) customer proprietary network information and personal information of directors, officers, employees, customers, agents, suppliers or contractors (hereinafter collectively referred to as “Confidential
Information”); provided, however, that, for purposes of this Agreement, the term Confidential Information shall not include any information that (i) was publicly known at the time of disclosure to Employee,
(ii) becomes publicly known or available thereafter other than by any means in violation of this Agreement or any other duty owed to the Company or any of its Affiliates by any person or entity; or (iii) is lawfully disclosed to Employee
by a third party. The Employee recognizes that such Confidential Information has been developed by the Company at great expense; is a valuable, special and unique asset of the Company which it uses in its business to obtain competitive advantage
over its competitors; is and shall be proprietary to the Company; is and shall remain the exclusive property of the Company; is not to be transmitted to any other person, entity or thing; and, is not to be used by Employee except in the course of
carrying our Employee’s duties and responsibilities of employment with the Company or its Affiliates. Accordingly, as a material inducement to the Company to enter into this Agreement with the Employee and in partial consideration for the
compensation payable hereunder to the Employee, the Employee hereby: 
 (i) warrants and represents that he has not disclosed,
copied, disseminated, shared or transmitted any Confidential Information to any person, firm, corporation or entity for any reason or purpose whatsoever, except in the course of carrying out the Employee’s duties and responsibilities of
employment with the Company or its Affiliates; 
  

 D-3 

 (ii) agrees to not disclose, copy, disseminate, share or transmit any Confidential
Information in the future using the same degree of care Employee uses for his own confidential information of similar importance, but in no event less than a reasonable standard of care; 

(iii) agrees not to make use of any Confidential Information for his own purposes or for the benefit of any person, firm, corporation or
other entity, except that, in the course of carrying out the Employee’s duties and responsibilities of employment, the Employee may use Confidential Information for the benefit of any Affiliate of the Company; 

(iv) warrants and represents that all Confidential Information in his possession, custody or control that is or was a property of the
Company has been or shall be returned to the Company by or on the date of the Employee’s termination; and 
 (v) agrees
that he will not reveal, or cause to be revealed, this Agreement or its terms to any third party (other than the Employee’s attorney, tax advisor, or spouse), except as required by law. 

The Employee’s covenants in this Section 6(a) of this Agreement are in addition to, and do not supercede, the Employee’s obligations under
any confidentiality, invention or trade secret agreements executed by the Employee, or any laws protecting the Company’s Confidential Information and, unless a longer period of time is required under applicable law, Employee’s obligations
under this Section 6(a) shall terminate two (2) years after a Change in Control. 
 (b)
Non-Solicitation. For a period commencing on the Termination Event and terminating at the end of the Severance Period, Employee shall not, either on Employee’s own account or jointly with or as a manager, agent, employee,
consultant, general partner, joint venture, majority owner or controlling shareholder or otherwise on behalf of any other person, firm or corporation, directly or indirectly solicit for employment any person who is an employee or officer of the
Company or its Affiliates and successors at the time of solicitation; provided, however, that a general advertisement to which an employee or officer of the Company, its Affiliates of their successors responds shall in no event be
deemed to result in a breach of this Section 6(b). 
 (c) Breach of Covenants. The Employee acknowledges that
the restrictions contained in Sections 6(a) and 6(b) of this Agreement correctly set forth the understanding of the parties at the time this Agreement is entered into, are reasonable and necessary to protect the legitimate interests of the Company.
The Employee also acknowledges that any breach of Sections 6(a) and 6(b) of this Agreement will cause substantial injury to the Company for which money damages will not be an adequate remedy. In the event of any such breach, the Company shall be
entitled, in addition to any other remedy, to seek a preliminary or permanent injunctive relief without the requirement to post a bond. If any court having jurisdiction shall find that any part of the restrictions set forth in this Agreement are
unreasonable in any respect, it is the intent of the parties that the restrictions set forth herein shall not be terminated, but that this Agreement shall remain in full force and effect to the extent (as to time periods and other relevant factors)
that the court shall find reasonable.

	7.	Applicable Law 

 This
Release shall be construed and interpreted pursuant to the laws of the State of Delaware without regard to its choice of law rules. 
  

	8.	Severability

with the clear intention that the validity and enforceability of the remaining parts, terms and provisions shall not be affected thereby. If any part, term, or provision is so found invalid, void or unenforceable, the applicability of any such part,
