 CABOT OIL & GAS CORPORATION SAVINGS INVESTMENT PLAN 
  
 (As Amended and Restated Effective January 1, 2001) 
  
 Recitals 
  
 Cabot Oil and Gas Corporation, a Delaware corporation (the “Company”), adopted the Cabot Corporation Profit
Sharing and Savings Plan and its related trust for the benefit of its eligible employees and the eligible employees of certain of its subsidiaries who might adopt said Plan, effective October 1, 1976 (the “1976 Plan”). 
  
 Effective January 1, 1991, the Board of Directors of the Company
authorized the establishment of the Cabot Oil and Gas Corporation Savings Investment Plan (the “Prior Plan”) to replace the 1976 Plan, and each Company employee’s accounts in the 1976 Plan and the Cabot Corporation Employee Stock
Ownership Plan were transferred to the Prior Plan at such time. The Prior Plan was subsequently amended by the First through Eleventh Amendments thereto. 
  
 Effective January 1, 2001, the Board of Directors of the Company authorized the amendment and restatement of the Prior Plan in the form set forth
herein (the “Plan”) to incorporate the prior amendments, to incorporate changes required by certain legislative acts, and to make certain other changes. There shall be no termination and no gap or lapse in time or effect between the Prior
Plan as in effect on December 31, 2000, and this Plan. 
  
 The Plan and the Trust, which is intended to form a part of the Plan, are intended to meet the requirements of Sections 401(a), 401(k) and 501(a) of the Internal Revenue Code of 1986, and the Employee Retirement Income Security
Act of 1974, as either may be amended from time to time. 
  
 The
provisions of this Plan shall apply to a Member who terminates Service on or after January 1, 2001. The rights and benefits, if any, of a former employee shall be determined in accordance with the provisions of the Prior Plan in effect on the
date his employment terminated. 
  
 NOW, THEREFORE, Cabot Oil and
Gas Corporation hereby amends, restates in its entirety, and continues the Cabot Oil & Gas Corporation Savings Investment Plan, effective January 1, 2001, a profit-sharing plan within the meaning of Code Section 401(a)(27), as
follows: 
  

 1 

 ARTICLE I 
  
 DEFINITIONS 
  
 As used in this Plan, the following words and phrases shall have the following meanings unless the context clearly requires a different meaning:

  
 1.1 Account: Collectively, the accounts maintained for
each Member pursuant to Section 5.1, and shall include accounts provided for in the Profit Sharing Plan. 
  
 1.2 Affiliate: A corporation or other trade or business that is not an Employer under this Plan but which together with the Company is “under
common control” within the meaning of Section 414(b) or (c), as modified by Section 415(h) of the Code; any organization (whether or not incorporated) which, together with the Company, is a member of an “affiliated service
group” within the meaning of Section 414(m) of the Code; and any other entity required to be aggregated with the Company pursuant to regulations under Section 414(o) of the Code. 
  
 1.3 After-Tax Contribution Account: The separate account maintained
for a Member to record his After-Tax Contributions to the Plan and adjustments relating thereto. 
  
 1.4 After-Tax Contributions: The amount contributed by a Member pursuant to Section 4.1B. 
  
 1.5 Authorized Leave of Absence: Any absence authorized by the
Employer or Affiliate under the Employer’s or Affiliate’s standard personnel practices provided that all persons under similar circumstances must be treated alike in the granting of such Authorized Leaves of Absence and provided further
that the Member returns within the period of authorized absence. 
  
 1.6 Beneficiary: A Member’s spouse, or such other natural person or persons, or the trustee of an inter vivos trust for the benefit of natural persons, entitled to benefits hereunder following a Member’s death. 

 
 1.7 Board of Directors: The Board of Directors of the Company.

  
 1.8 Code: The Internal Revenue Code of 1986, as now in
effect or hereafter amended. 
  
 1.9 Committee: The
Administrative Committee appointed by the Company to act as administrator of the Plan and to perform the duties described in Article II. 
  
 1.10 Company: Cabot Oil and Gas Corporation, a Delaware corporation, its predecessors and successors. 
  
 1.11 Compensation: The total non-deferred remuneration actually paid
to a Member by the Employer for personal services rendered as an Employee, as reported on the Member’s Federal Income Tax Withholding Statement (Form W-2 or its subsequent equivalent) during the 
  

 2 

 
applicable Plan Year and any amounts by which a Member’s normal remuneration is reduced pursuant to a voluntary salary reduction plan qualified under
Section 125 of the Code, a qualified transportation fringe under Section 132(f) of the Code or a cash-or-deferred plan qualified under Section 401(k) of the Code, including salary, wages, overtime payments, and annual, discretionary
and sign-on bonuses, but excluding any amounts contributed by or on behalf of an Employer to this Plan or any other employee benefit plan sponsored by the Company, non-deductible moving expenses, disability pay (both short-term and long-term), any
income arising from the exercise of a stock option or from the receipt of a restricted stock award, reimbursements, expense allowances, severance pay (whether periodic or in a lump sum), taxable fringe benefits, waiver benefits, deductible payments
under Section 105(h) of the Code, taxable group-term life insurance benefits, and retention and relocation bonuses. The Compensation of a Member as reflected on the books and records of the Employer shall be conclusive. 
  
 Notwithstanding anything herein to the contrary, in no event shall the
Compensation taken into account under the Plan for any Employee exceed $170,000 or such other dollar amount as may be prescribed by the Commissioner for increases in the cost of living in accordance with Section 401(a)(17)(B) of the Code. The
cost-of-living adjustment in effect for a calendar year applies to any period, not exceeding 12 months, over which Compensation is determined (determination period) beginning in such calendar year. If a determination period consists of fewer than 12
months, the Compensation limit will be multiplied by a fraction, the numerator of which is the number of months in the determination period, and the denominator of which is 12. If Compensation for any prior determination period is taken into account
in determining an Employee’s benefits accruing in the current Plan Year, the Compensation for that prior determination period is subject to the Compensation limit in effect for that prior determination period. 
  
 1.12 Contribution: Any amount contributed to the Trust Fund pursuant
to the provisions of this Plan, by an Employer or by a Member out of his Compensation. Contributions by the Employer shall sometimes be referred to as “Employer Contributions” and “Pre-Tax Contributions,” as specified under
Sections 4.1 and 4.2 hereof. 
  
 1.13 ERISA: Public
Law No. 93-406, the Employee Retirement Income Security Act of 1974, as amended from time to time. 
  
 1.14 Effective Date: January 1, 1991, the date as of which the provisions of the Prior Plan first became effective. 
  
 1.15 Employee: Any person who, on or after the Effective Date, is
receiving remuneration for personal services (or would be receiving such remuneration except for an authorized leave of absence) as an employee of an Employer or who is a Leased Employee. 
  
 1.16 Employer: The Company, its successors, and any eligible organization which shall adopt this Plan pursuant to the
provisions of Article X, and the successors, if any, to such organization. 
  

 3 

 1.17 Employer Contribution Account: The account maintained for a Member to record his share of the
Contributions of his Employer and adjustments relating thereto. 
  
 1.18 Employment Year: The twelve consecutive month period determined from the Employee’s first performance of an Hour of Service and subsequent twelve-month periods beginning on the first anniversary of such Employee’s
performance of such Hour of Service; provided, however, that in the case of any Employee who incurs a Break In Service, upon such Employee’s re-employment his Employment Year shall be deemed to commence on the date he first performs an Hour of
Service after such Break In Service. 
  
 1.19 Entry Date:
The first day of each calendar month and any such other date as determined by the Committee, communicated to the Employees and applied in a uniform and non-discriminatory manner thereafter. 
  
 1.20 ESOP: The Cabot Corporation Employee Stock Ownership Plan, as
effective December 31, 1990. 
  
 1.21 ESOP Account:
The account maintained for a Member who participated in the ESOP to record his contributions transferred from the ESOP to this Plan and adjustments relating thereto. Effective October 16, 2000, a Member shall be eligible to transfer the assets
held in the Member’s ESOP Account to other Investment Funds provided under the Plan or to borrow assets from such account as provided under Section 6.5 of the Plan. 
  
 1.22 Forfeiture: The portion of a Member’s Employer Contribution Account which is forfeited because of
termination of Service before full vesting pursuant to Section 7.4 and which occurs on the earlier of (a) the distribution of the entire vested portion of the Member’s Account or (b) the last day of the Plan Year in which the
Member incurs five (5) consecutive one-year Breaks In Service. 
  
 1.23 Hour(s) of Service: An Hour of Service is each hour during an applicable computation period for which an Employee is directly or indirectly paid, or entitled to payment, by an Employer or an Affiliate for the performance of
duties or for any period of Authorized Leave of Absence. Moreover, an Hour of Service is each hour, not in excess of forty hours per week, during any period of unpaid Authorized Leave of Absence with an Employer or an Affiliate. Such Hours of
Service shall be credited to the Employee for the computation period in which such duties were performed or in which such Authorized Leave of Absence occurred. An Hour of Service also includes each hour, not credited above, for which back pay,
irrespective of mitigation of damages, has been either awarded or agreed to by an Employer or an Affiliate. These Hours of Service shall be credited to the Employee for the computation period to which the award or agreement pertains rather than the
computation period in which the award, agreement or payment is made. In determining an Employee’s total Hours of Service during a computation period, a fraction of an hour shall be deemed a full Hour of Service. 
  
 Instead of counting and crediting actual hours worked, for purposes of
determining the number of Hours of Service to be credited to an Employee, an Employee may be credited with 190 Hours of Service for each calendar month during which he has earned one 

  

 4 

 
Hour of Service. For purposes of determining the number of Hours of Service to be credited for reasons other than the performance of duties and for purposes
of determining to which computation period Hours of Service earned under any provision of this Plan are to be credited, the provisions of Department of Labor Regulation Section 2520.200(b)-2(b) and (c) are hereby incorporated by reference
as if fully set forth herein. 
  
 Hours of Service will be
credited for employment with other members of an affiliated service group (under Code Section 414(m)), a controlled group of corporations (under Code Section 414(b)), or a group of trades or businesses under common control (under Code
Section 414(c)), of which the Company is a member. However, Hours of Service shall not be credited for employment with such an affiliated service group, a controlled group, or a group of trades or businesses prior to its becoming a member of or
after its cessation of membership in the Company’s affiliated service group, controlled group, or group of trades or businesses. Hours of Service will be credited for any individual considered an employee under Code Section 414(n).

  
 1.24 Income of the Trust Fund: The net gain or loss of
the Trust Fund from investments, as reflected by interest payments, dividends, realized and unrealized gains and losses on securities and other investment transactions and expenses paid from the Trust Fund. 
  
 1.25 Investment Fund(s): Any of the investment funds comprising the
Trust Fund, as described in Section 9.2.

Employee or Member to complete and file with the Committee an application for a benefit and all other forms approved by the Committee, and to furnish all pertinent information requested by the Committee. The Committee may rely on such information so
furnished it, including the Employee’s or Member’s current mailing address. 
  
 2.10 Committee Liability: Except to the extent that such liability is created by ERISA, no member of the Committee shall be liable for any act or omission of any other member of the Committee, nor for any act
or omission on his own part except for his own gross negligence or wilful misconduct, nor for the exercise of any power or discretion in the performance of any duty assumed by him hereunder. The Company shall indemnify and hold harmless each member
of the Committee from any and all claims, losses, damages, expenses (including counsel fees approved by the Committee), and liabilities (including any amounts paid in settlement with the Committee’s approval but excluding any excise tax
assessed against any member or members of the Committee pursuant to the provisions of Section 4975 of the Code) arising from any act or omission of such member in connection with duties and responsibilities under the Plan, except when the same
is judicially determined to be due to the gross negligence or wilful misconduct of such member. 
  

 10 

 2.11 Statements: As soon as practicable after each Valuation Date, the Committee shall prepare and
deliver to each Member a written statement showing as of that Valuation Date:

 (b) The amount of Employer Contributions allocated to his Employer Contribution Account and the amount of his Contributions for the Plan

 (c) The
adjustments to his Account to reflect his share of income and expenses of the Trust Fund and appreciation or depreciation in Trust Fund assets during the Plan Year ending on such Valuation Date;

 (e) Such information as the

2.12 Annual Audit: If required by ERISA, the Committee shall engage, on behalf of all Members, an independent Certified Public Accountant who
shall conduct an annual examination of any financial statements of this Plan and Trust and of other books and records of this Plan and Trust as the Certified Public Accountant may deem necessary to enable him to form and provide a written opinion as
to whether the financial statements and related schedules required to be filed with the Department of Labor or furnished to each Member are presented fairly and in conformity with generally accepted accounting principles applied on a basis
consistent with that of the preceding Plan Year. If, however, the statements required to be submitted as part of the reports to the Department of Labor are prepared by a bank or similar institution or insurance carrier regulated and supervised and
subject to periodic examination by a state or federal agency and if such statements are certified by the preparer as accurate and if such statements are, in fact, made a part of the annual report to the Department of Labor and no such audit is
required by ERISA, then the audit required by the foregoing provisions of this Section shall be optional with the Committee. 
  
 2.13 Funding Policy: The Committee shall, at a meeting duly called for such purpose, establish a funding policy and method consistent with the
objectives of the Plan and the requirements of Title I of ERISA. The Committee shall meet at least annually to review such funding policy and method. In establishing and reviewing such funding policy and method, the Committee shall endeavor to
determine the Plan’s short-term and long-term objectives and financial needs, taking into account the need for liquidity to pay benefits and the need for investment growth. All actions of the Committee taken pursuant to this Section and the
reasons therefor shall be recorded in the minutes of meetings of the Committee and shall be communicated to the Trustee, any Investment Manager who may be managing a portion or all of the Trust Fund in accordance with the provisions of the Trust
Agreement, and to the Board of Directors. 
  

 11

the members of the Committee, the Committee may (i) allocate among any of the members of the Committee any of the responsibilities of the Committee under the Plan and Trust Agreement and/or (ii) designate any person, firm or corporation
that is not a member of the Committee to carry out any of the responsibilities of the Committee under the Plan and/or Trust Agreement. Any such allocation or designation shall be made pursuant to a written instrument executed by a majority of the
members of the Committee. 
  
 2.15 Presenting Claims for

so, the amount thereof and shall notify the claimant of its findings. Benefits under the Plan will be paid only if the Committee decides in its discretion that the applicant is entitled to them. 
  
 If a claim is wholly or partially denied, the Committee shall so notify the
claimant within ninety (90) days after receipt of the claim by the Committee, unless special circumstances require an extension of time for processing the claim. If such an extension of time for processing is required, written notice of the

 If notice of denial is not furnished, and if the claim is not granted within the period of
time set forth above, the claim shall be deemed denied for purposes of proceeding to the review stage described in Section 2.16. 
  
 2.16 Claims Review Procedure: If an application filed by a Member or Beneficiary under Section 2.15 above shall result in a denial by the
Committee of the benefit applied for, either in whole or in part, such applicant shall have the right, to be exercised by written application filed with the Committee within sixty (60) days after receipt of notice of the denial of his
application or, if no such notice has been given, within sixty (60) days after the application is deemed denied under Section 8.4, to request the review of his application and of his entitlement to the benefit applied for. Such request for
review may contain such additional information and comments as the applicant may wish to present. Within sixty (60) days after receipt of any such request for review, the Committee shall reconsider the application for the benefit in light of
such additional information and comments as the applicant may have presented, and if the applicant shall have so requested, shall afford the applicant or his designated representative a hearing before the Committee. The Committee shall also permit
the applicant or his designated representative to review pertinent documents in its possession, including copies of the Plan document and information provided by the Company relating to the applicant’s entitlement to such benefit. The Committee
shall make a final determination with respect to the applicant’s application for review as soon as practicable, and in any event not later than sixty (60) days after receipt of the aforesaid request for review, except that under special
circumstances, such as the necessity for holding a hearing, such sixty-day period may be extended to the extent necessary, but in no event beyond the expiration of one hundred twenty (120) days after receipt by the Committee of such request for
review. If such an extension of time for review is required because of special circumstances, written notice of the extension shall be furnished to the applicant prior to the commencement of the extension. Notice of such final determination of the
Committee shall be furnished to the applicant in writing, in a manner calculated to be understood by him, and shall set forth the specific reasons for the decision and specific references to the pertinent provisions of the Plan upon which the

 ARTICLE III 
  
 PARTICIPATION AND SERVICE 
  
 3.1 Eligibility for Participation: An Employee participating under the Prior Plan immediately preceding January 1, 2001 shall continue to
participate in accordance with the provisions of this Plan. Each other Employee shall be eligible to commence participation in this Plan on the Entry Date coincident with or next following his commencement of Service, provided he is otherwise
eligible hereunder. An Employee who does not participate in the Plan when he first becomes eligible may commence participation on any Entry Date thereafter, provided he is otherwise eligible hereunder. 
  
 Notwithstanding anything to the contrary in this Plan, the following
Employees shall not be eligible to participate in the Plan: (i) Leased Employees, (ii) employees covered by a collective bargaining agreement between employee representatives and the Employer, if there is evidence that retirement benefits
were the subject of good faith bargaining between such employee representatives and the Employer and such collective bargaining agreement does not expressly provide for coverage of such employees hereunder, (iii) persons who are non-resident
aliens and who receive no earned income (within the meaning of Code Section 911) from the Employer which constitutes income from sources within the United States (within the meaning of Code Section 861), and (iv) persons who are
utility employees (as herein defined). For purposes of this Plan, a utility employee is an employee who is hired in a utility position. A utility position is (i) a position which is expected by the respective Employer or Affiliate to be of
limited duration or (ii) for a particular project upon the conclusion of which the employee is expected by the respective Employer or Affiliate to be terminated. 
  
 3.2 Notification of Eligible Employees: The Committee, which shall be the sole judge of the eligibility of an
Employee to participate under the Plan, shall notify each Employee of his initial eligibility to participate in the Plan.

 (a) Absence due to accident or sickness so long as the person is continued on the employment rolls of the
Employer or Affiliate and remains eligible to return to work upon his recovery; 
  

 13 

 (b) Absence due to membership in the service of the Armed Forces of the United States
(but if such absence is not pursuant to orders issued by the Armed Forces of the United States, only if with the consent of the Employer or Affiliate) but only if, and then only to the extent that, applicable federal law requires such military
service to be counted as Service hereunder and only if the person has complied with all prerequisites of such federal law; and 
  
 (c) Absence due to an authorized leave of absence granted by the Employer or Affiliate for any other purpose approved by the Board of
Directors in accordance with established practices of the Employer or Affiliate, consistently applied in a non-discriminatory manner in order that all employees under similar circumstances shall be treated alike, provided that each such person
shall, immediately upon the expiration of such leave, apply for reinstatement in the employment of the Employer or Affiliate. 
  
 3.5 Break In Service: For purposes of the Plan, a “Break In Service” shall mean a Plan Year within which a Member completes less than 501
Hours of Service. Solely for purposes of determining whether a Member has a Break In Service for eligibility or vesting purposes an individual who is absent from work for maternity or paternity reasons shall receive credit for the Hours of Service
which would have otherwise been credited to such an individual but for such absence, or in any case in which such hours cannot be determined, eight hours of service per day of such absence. For purposes of this paragraph, an absence from work for
maternity or paternity reasons means an absence (a) by reason of the pregnancy of the individual, (b) by reason of the birth of a child of the individual, (c) by reason of the placement of a child with the individual in connection
with the adoption of such child by such individual, or (d) for purposes of caring for such child for a period beginning immediately following such birth or placement. The Hours of Service credited under this paragraph shall be credited
(i) in the computation period in which the absence begins if the crediting is necessary to prevent a Break In Service in that period or (ii) in all other cases, in the following computation period. No more than 501 Hours of Service shall
be credited for any single such absence. 
  
 3.6 Participation
and Vesting Service Upon Re-employment Before a Break In Service: Upon the re-employment before a Break In Service of any person who had previously been employed by an Employer or Affiliate on or after the Effective Date, the following rules
shall apply. If the re-employed person was not a Member during his prior period of Service, he shall be eligible to commence participation in the Plan on the first Entry Date after his re-employment upon meeting the requirements of Section 3.1.
If the re-employed person was a Member in the Plan during his prior period of Service, he shall be entitled to recommence participation as of the date of his re-employment if eligible under Section 3.1. All years of Vesting Service attributable
to a re-employed person’s prior period of Service shall be reinstated as of the date of his re-employment for purposes of Section 7.4. 
  
 3.7 Participation and Vesting Service Upon Re-employment After a Break In Service: Upon the re-employment after a Break In Service of any person
who had previously been employed by an Employer or Affiliate on or after the Effective Date, the following rules shall apply in determining his eligibility for participation and his Vesting Service: 
  

 14 

 (a) Participation: If an Employee (whether or not previously a Member) is rehired
after cancellation of pre-break Service as determined in accordance with subparagraph (b) below, he must meet the requirements of Section 3.1 for participation in the Plan as if he were a new Employee. If an Employee is rehired prior to
cancellation of his pre-break Service as determined in accordance with subparagraph (b) below, he shall be eligible to commence or recommence participation as of the date of his re-employment, if he previously was a Member and he meets the
requirements under Section 3.1, or on the first Entry Date after his re-employment as of which he has completed the requirements of Section 3.1. 
  
 (b) Vesting Service: If the re-employed person was a Member whose prior Service terminated without entitlement to a distribution
from his Employer Contribution Account under Article VII, any Vesting Service attributable to his prior period of employment shall be reinstated as of the date of his recommencement of participation only if the number of consecutive one-year
Breaks In Service is less than the greater of five (5) or the aggregate number of his years of pre-break Vesting Service. If the re-employed person was a Member whose prior Service terminated with entitlement to a distribution from his Employer
Contribution Account under Article VII, all years of Vesting Service attributable to his prior period of employment shall be reinstated upon his recommencing participation in the Plan. 
  
 3.8 Vesting Service: An Employee shall be credited with one and only
one year of Vesting Service for each Plan Year in which such Employee completes at least 1,000 Hours of Service for an Employer or Affiliate. An Employee will not be credited with a year of Vesting Service with respect to a Plan Year if the Employee
completes less than 1,000 Hours of Service for the Employer or an Affiliate during such Plan Year. An Employee’s service with Cabot Corporation prior to the Effective Date shall count as Vesting Service under this Plan to the extent and in the
same manner as computed under the Profit Sharing Plan. 
  
 3.9
Transferred Members: If a Member is transferred to an Affiliate, or to an employment classification with an Employer which is not covered by this Plan, his participation shall be suspended until he is subsequently re-employed by an Employer
in an employment classification covered by the Plan; provided, however, that during such suspension period (i) such Member shall be credited with Service in accordance with Section 3.4, (ii) he shall not be entitled or required to
make Savings Contributions under Section 4.1, (iii) his Employer Contribution Account shall receive no Employer Contribution except to the extent provided in Section 4.2, and (iv) his Account shall continue to share
proportionately in Income of the Trust Fund as provided in Section 5.2. If an individual is transferred from an employment classification with an Employer that is not covered by the Plan to an employment classification that is so covered, or
from an Affiliate to an employment classification with an Employer that is so covered, his period of Service prior to the date of transfer shall be considered for purposes of determining his eligibility to become a Member under Section 3.1 and
for purposes of vesting under Section 7.4.

this Plan to the contrary, contributions, benefits and service credit with respect to qualified military service will be provided in accordance with Section 414(u) of the Code.

 ARTICLE IV 
  
 CONTRIBUTIONS AND FORFEITURES 
  
 4.1 Savings Contributions: Each Member may designate up to fifteen percent (15%) of his Compensation as Pre-Tax and/or After-Tax Contributions
as described herein. 
  
 A. Pre-Tax Contributions: Each
Member who elects to make Pre-Tax Contributions for a Plan Year shall initially elect to defer a portion of his Compensation in whole percentages of not less than one percent (1%) and not more than fifteen percent (15%) (to the nearest
whole dollar) of his Compensation; provided, however, that Pre-Tax Contributions and After-Tax Contributions under this Section 4.1 shall not total, in the aggregate, more than fifteen percent (15%) (to the nearest whole dollar) of the
Member’s Compensation. Such deferred percentage shall be applied against a Member’s Compensation as such Compensation becomes payable. Each such election shall continue in effect during subsequent Plan Years unless the Member notifies the
Committee, in writing and in such form and manner prescribed by the Committee, of his election to change or discontinue his Pre-Tax Contribution. A Member may change the percentage of his Compensation designated by him as his Pre-Tax Contribution,
but not retroactively and not more frequently than four (4) times each Plan Year. A Member’s Pre-Tax Contributions shall not exceed a maximum of $10,500 as adjusted by the Secretary of the Treasury to account for cost-of-living increases.
In the event a Member’s Pre-Tax Contributions exceed the applicable $10,500 limit, or in the event the Member submits a written claim to the Committee, at the time and in the manner prescribed by the Committee, specifying an amount of Pre-Tax
Contributions that will exceed the applicable limit of Section 402(g) of the Code when added to amounts deferred by the Member in other plans or arrangements, such excess (the “Excess Deferrals”), plus any income and minus any loss
attributable thereto, shall be returned to the Member by April 15 of the following year. Such income shall include the allocable gain or loss for (i) the Plan Year in which the Excess Deferral occurred and (ii) the period from the end
of that Plan Year to the date of distribution. The amount of any Excess Deferrals to be distributed to a Member for a taxable year shall be reduced by excess Pre-Tax Contributions previously distributed pursuant to Article XIV for the Plan Year
beginning in such taxable year. The income or loss attributable to the Member’s Excess Deferral for the Plan Year shall be determined by multiplying the income or loss attributable to the Member’s Pre-Tax Contribution Account balance for
the Plan Year (or relevant portion thereof) by a fraction, the numerator of which is the Excess Deferral and the denominator of which is the Member’s total Pre-Tax Contribution Account balance as of the Valuation Date next preceding the date of
return of the Excess Deferral. Unless the Committee elects otherwise, the income or loss attributable to the Member’s Excess Deferral for the period between the end of the Plan Year and the date of distribution shall be determined using the
safe-harbor method set forth in Treasury Regulations to Section 402(g) of the Code, and shall be equal to ten percent (10%) of the allocable income or loss for the Plan Year, calculated as set forth immediately above, multiplied by the
number of calendar months that have elapsed since the end of the Plan Year. For these purposes, distribution of an Excess Deferral on or before the fifteenth (15th) day of a calendar month shall be treated as having been made on the last day of
the preceding month, and a distribution made thereafter shall be treated as having been made on the first day of the next month. Any Excess Deferrals which have not been returned to the Member by April 15 of the following year shall be 

  

 17 

 
treated as Annual Additions under Article XII of the Plan. Each Member’s Pre-Tax Contribution shall be contributed to the Trust Fund by the Employer. A
Member shall always be fully vested in and have a non-forfeitable right to his Pre-Tax Contributions. 
  
 B. After-Tax Contributions: Any Member regardless of whether he has elected to defer any whole percentage of his Compensation in the form of a
Pre-Tax Contribution to the Plan may elect to make an After-Tax Contribution of up to fifteen percent (15%) (to the nearest whole dollar) of his Compensation; provided, however, that Pre-Tax Contributions and After-Tax Contributions under this
Section 4.1 shall not total, in the aggregate, more than fifteen percent (15%) (to the nearest whole dollar) of the Member’s Compensation. Such a deferred percentage shall be applied against a Member’s Compensation as such
Compensation becomes payable. Any After-Tax Contribution election shall be made pursuant to the provisions of Section 3.3, and shall continue in effect during subsequent Plan Years unless the Member notifies the Committee, in writing and in
such form and manner prescribed by the Committee, of his election to change or discontinue his After-Tax Contribution. A Member may change the percentage of his Compensation designated by him as his After-Tax Contribution; provided, however, that he
may not change his Pre-Tax and After-Tax Contribution elections in the aggregate more than four (4) times each Plan Year and that such changes shall not be retroactive. A Member shall always be fully vested in and have a non-forfeitable right
to his After-Tax Contributions. 
  
 4.2 Employer
Contributions: Each Employer shall make an Employer Contribution to the Trust Fund for a Plan Year on behalf of its Members in an amount equal to one hundred percent (100%) of such Member’s Basic Savings Contributions for the Plan
Year. “Basic Savings Contributions” means each Member’s first six percent (6%) of Pre-Tax Contributions. An Employer Contribution shall be deemed to be made on account of a Plan Year if (i) the Employer claims such amount as
a deduction on its federal income tax return for such Plan Year or (ii) the Employer designates such amount in writing to the Trustee as payment on account of such Plan Year. All Employer Contributions shall be paid to the Trustee, and payment
shall be made not later than the time prescribed by law for filing the federal income tax return of the Employer, including any extension which has been granted for the filing of such tax return. The Trustee shall hold all such Employer
Contributions subject to the provisions of this Plan and Trust, and no part of such Contributions shall be used for, or diverted to, any other purpose. The foregoing not withstanding, with respect to a Member who defers his Compensation at a rate of
6% or more and who, prior to the end of the Plan Year, ceases his contributions because of the limits imposed by Code Section 402(g), Employer Contributions to his Employer Contribution Account shall be made each pay period for such Plan Year
in such an amount that the aggregate of such contributions for such Plan Year is equal to the amount provided by the Employer pursuant to this Section. 
  
 In the case of the reinstatement of any amounts forfeited pursuant to the unclaimed benefit provisions of Section 11.10, the Employer shall also
contribute, within a reasonable time after a claim is filed under Section 11.10, an amount sufficient to reinstate such amount. All such “Employer Minimum Contributions” shall be transmitted to the Trustee as soon as practicable after
such contributions are made. 
  

 18 

 4.3 Employer Contributions and Pre-Tax Contributions to be Tax Deductible: Employer Contributions
and Pre-Tax Contributions shall not be made in excess of the amount deductible under applicable federal law now or hereafter in effect limiting the allowable deduction for contributions to profit-sharing plans. The Employer Contributions and Pre-Tax
Contributions to this Plan, when taken together with all other contributions made by the Employer to other qualified retirement plans, shall not exceed the maximum amount deductible under Section 404 of the Code. 
  
 4.4 Suspension of Contributions: Any Member may, by written direction
to his Employer, suspend his Pre-Tax Contributions and/or After-Tax Contributions at any time by giving at least twenty-one (21) days’ notice. In the case of any suspension of Pre-Tax Contributions and/or After-Tax Contributions, the
Employer Contributions will automatically cease. Pre-Tax Contributions and/or After-Tax Contributions which are not made during a period of suspension shall not be made up retroactively. 
  
 4.5 Delivery to Trustee: Each Employer shall, not less frequently than monthly, pay the Contributions to the Trustee.

  
 4.6 Application of Funds: The Trustee shall hold or
apply the Contributions so received by it subject to the provisions of the Plan; and no part thereof (except as otherwise provided in the Trust Agreement) shall be used for any purpose other than the exclusive use of the Members or their
Beneficiaries. 
  
 4.7 Rollover Amounts: Any Member may
file with the Committee a written request that the Trustee accept a Rollover Amount from such Member. The Committee, in its sole and absolute discretion, shall determine whether such Member shall be permitted to contribute a Rollover Amount to the
Trust Fund. The Committee shall develop such procedures and may require such information from the Employee or Member desiring to make such a transfer as it deems necessary or desirable to determine that the proposed transfer will meet the
requirements of this Section. Upon approval by the Committee, the amount transferred shall be deposited in the Trust Fund and shall be credited to a separate Rollover Account. Such account shall at all times be one hundred percent (100%) vested
in the Employee or Member and shall share in the Income of the Trust Fund in accordance with Section 5.2. Upon termination of employment, the total amount of the Rollover Account shall be distributed in accordance with Article VIII.

  
 Upon such a transfer by an Employee who is otherwise eligible
to participate in the Plan but who has not yet completed the participation requirements of Section 3.1, his Rollover Account shall represent his sole interest in the Plan until he becomes a Member. In all respects, the Rollover Account shall be
treated as a regular account under this Plan and shall be subject to the investment directions of the Member and the change thereof as otherwise permitted herein. 
  
 4.8 Disposition of Forfeitures: If a Member terminates Service without being entitled to receive a distribution from
his Employer Contribution Account, he shall be deemed to have received a distribution from that Account as of the date of his termination of Service. Upon termination of Service, a Member’s Forfeiture (as defined in Section 1.21), if any,
shall first be 
  

 19 

 
credited to the Employer Contribution Account of a re-employed Member for whom a reinstatement of prior Forfeitures is required pursuant to Section 7.4
hereof, and second shall be applied toward the Account of a former Member pursuant to the unclaimed benefit provisions of Section 11.10 hereof. To the extent that Forfeitures for any Plan Year exceed the amounts required to reinstate the
Accounts noted above, they will be applied against the next succeeding Employer Contribution. 
  
 4.9 Contributions Generally Irrevocable: All Employer contributions to the Trust Fund shall be irrevocable and shall be used to pay benefits or to pay expenses of the Plan and Trust Fund; provided, however,
that upon the Employer’s request, a contribution which was made by a mistake of fact or conditioned upon initial qualification of the Plan and Trust Fund under Sections 401(a) and 501(a) of the Code, or upon the deductibility of the
contribution under Section 404 of the Code, shall be returned to the Employer within one (1) year after the payment of the contribution, the denial of initial qualification or the disallowance of the deduction (to the extent disallowed),
whichever is applicable. 
  

 20 

 ARTICLE V 
  
 MEMBER ACCOUNTS 
  
 5.1 Individual Accounts: The Committee shall create and maintain adequate records to disclose the interest in the Trust Fund and in its component
Investment Funds of each Member, former Member and Beneficiary. Such records shall be in the form of individual accounts and credits and charges shall be made to such accounts in the manner herein described. A Member may have up to nine
(9) separate accounts, including but not limited to, an Employer Contribution Account, a Pre-Tax Contribution Account, an After-Tax Contribution Account, a Profit Sharing Plan Account, an ESOP Account and a Rollover Account. Any Member who
transfers from one Employer to another Employer, or who is simultaneously employed by two or more Employers, may have individual accounts with each such Employer. The maintenance of individual Accounts is only for accounting purposes, and a
segregation of the assets of the Trust Fund to each Account shall not be required. Distribution and withdrawals made from an Account shall be charged to the Account as of the date paid. 
  
 5.2 Account Adjustments: The Accounts of Members, former Members and Beneficiaries shall be adjusted each Plan Year
in accordance with the following: 
  
 (a)
Income of the Trust Fund: Each Valuation Date, the Trustee shall value the Trust Fund at its then market value to determine the amount of Income of the Trust Fund. The Income of the Trust Fund since the preceding Valuation Date (including the
appreciation or depreciation in value of the assets of the Investment Fund) shall be allocated to the Accounts of Members in proportion to the balances in such Accounts on the preceding Valuation Date, but after first reducing each such Account
balance by any distribution from such Account since the preceding Valuation Date and increasing such Account balance by any Contributions and loan payments since the preceding Valuation Date. 
  
 (b) Savings Contributions: As of each Valuation Date
during the Plan Year, the Trustee shall allocate to each respective Member’s Pre-Tax Contribution Account his Pre-Tax Contributions to the Plan made since the preceding Valuation Date. As of each Valuation Date during the Plan Year, the Trustee
shall also allocate to each respective Member’s After-Tax Contribution Account his After-Tax Contributions made since the preceding Valuation Date. 
  
 (c) Employer Contributions: No less frequently than the Annual Valuation Date and more frequently as may be specified by the
Committee, the Employer Contribution for such Plan Year shall be allocated among its Members during such Plan Year or partial Plan Year in the ratio that each Member’s unwithdrawn Basic Savings Contributions for the Plan Year or partial Plan
Year bears to the total unwithdrawn Basic Savings Contributions of all such Members for the Plan Year or partial Plan Year. 
  

 21 

 (d) Forfeitures: Forfeitures which have become available for reallocation during
such Plan Year shall be applied pursuant to Section 4.8. 
  
 (e) Employer Minimum Contributions: Employer Minimum Contributions shall be used solely to reinstate Accounts in accordance with Section 7.4 and to restore Accounts pursuant to Section 11.10 whenever
the Forfeitures available for such reinstatement or restoration are insufficient. 
  
 5.3 Recognition of Different Investment Funds: As provided in Article IX, Investment Funds shall be established and each Member shall direct, within the limitations set forth in Sections 9.3 and 9.4, what
portion of the balance in his Accounts on a pro rata basis, if any, shall be deposited in each Investment Fund. Consequently, when appropriate, a Member shall have an Employer Contribution Account, Pre-Tax Contribution Account, After-Tax
Contribution Account, Profit Sharing Plan Account and Rollover Account in each such Investment Fund and the allocations described in Section 5.2 shall be adjusted in such manner as is appropriate to recognize the existence of the Investment
Funds. Because Members have a choice of Investment Funds, any reference in this Plan to an Employer Contribution Account, Pre-Tax Contribution Account, After-Tax Contribution Account, Profit Sharing Plan Account or Rollover Account shall be deemed
to mean and include all accounts of a like nature which are maintained for the Member under each Investment Fund. 
  
 5.4 Valuation of Trust Fund: A valuation of the Trust Fund shall be made as of each Valuation Date and on any other date during the Plan Year that
the Committee deems a valuation to be advisable. Any such interim valuation shall be exercised on a uniform and non-discriminatory basis. For the purposes of each valuation, the assets of each Investment Fund shall be valued at the respective
current market values, and the amount of any obligations for which the Investment Fund may be liable, as shown on the books of the Trustee, shall be deducted from the total value of the assets. For the purposes of maintenance of books of account in
respect of properties comprising the Trust Fund, and of making any such valuation, the Trustee shall account for the transactions of the Trust Fund on a modified cash basis. The current market value shall, for the purposes hereof, be determined as
follows: 
  
 (a) Where the properties are
securities which are listed on a securities exchange, or which are actively traded over the counter, the value shall be the last recorded bid and asked prices, whichever shall be the later. In the event transactions regarding such property are
recorded over more than one such exchange, the Trustee may select the exchange to be used for purposes hereof. Recorded information regarding any such securities published in The Wall Street Journal or any other publication deemed appropriate
may be relied upon by the Trustee. If no transactions involving any such securities have been recorded within ten (10) days prior to the particular Valuation Date, such securities shall be valued as provided in paragraph (b) below.

  
 (b) Where paragraph (a) hereof shall be
inapplicable in the valuation of any properties, the Trustee shall obtain from at least two (2) qualified persons an opinion as to the value of such properties as of the close of business on the particular Valuation Date. The average of such
estimates shall be used.

 ARTICLE VI 
  
 WITHDRAWALS AND LOANS 
  
 6.1 Withdrawals from Profit Sharing Plan Account: Each Member with a Profit Sharing Plan Account shall be entitled to withdraw such amounts that
were transferred to this Plan. The following withdrawals are permitted only from a Member’s Profit Sharing Plan Account: 
  
 A. Voluntary Withdrawals: Each Member of the Plan, upon giving written notice to the Committee (in such form and in such manner as prescribed by
the Committee) shall be entitled to withdraw from his Profit Sharing Plan Account (valued as of the Valuation Date preceding the actual date of the withdrawal) any amount, not to exceed the balance of such Account, as of such date. Voluntary
withdrawals shall be limited to two such withdrawals per year and further limited to only one such withdrawal in any given three-month period. Voluntary withdrawals shall be deducted from a Member’s Profit Sharing Plan Account in the following
order: 
  
 4. Profit Sharing Plan after-tax
contributions made before January 1, 1987. 
  
 5. Profit Sharing Plan after-tax contributions including investment earnings made after December 31, 1986. 
  
 6. Profit Sharing Plan investment earnings on after-tax contributions made before January 1, 1987. 
  
 7. Profit Sharing Plan vested employer contributions
including investment earnings. 
  
 Notwithstanding any of the foregoing, the
vested portion of employer contributions may only be withdrawn from the Profit Sharing Plan Account 24 months after such amounts were contributed to the Profit Sharing Plan. 
  
 B. Hardship Withdrawals: The following hardship withdrawals shall be allowed: 
  
 1. A Member may make a hardship withdrawal from his Profit
Sharing Plan Account if the Member has already made two voluntary withdrawals or if three (3) months have not elapsed since the previous voluntary withdrawal. 
  
 2. A Member may at any time file with the Committee an appropriate written request for a hardship withdrawal
of an amount from the pre-tax contribution account in his Profit Sharing Plan Account. Notwithstanding the foregoing, a Member may not withdraw any Income of the Trust Fund allocated to his pre-tax contribution account in his Profit Sharing Plan
Account on or after January 1, 1989. The approval or disapproval of such request shall be made 

  

 23 

 
within the sole discretion of the Committee except that the Committee shall not approve any such request for a withdrawal unless it has been presented a
certification by the Member that he is facing a hardship creating an immediate and substantial financial need and that the resources necessary to satisfy that financial need are not reasonably available from other sources of the Member. A Member
must first withdraw any available amount credited to the after-tax account and the vested portion of his employer contribution account in his Profit Sharing Plan Account in order to be permitted to make a hardship withdrawal from the pre-tax
contribution account in his Profit Sharing Plan Account, and must also have taken all distributions and loans otherwise available under this Plan and all employee plans maintained by the Member’s Employer. The amount of the hardship withdrawal
shall be limited to that amount which the Committee determines to be required to meet the immediate financial need created by the hardship. The hardship withdrawal shall be made in cash as soon as practicable after the Member submits the hardship
request and the dollar amount withdrawn shall be determined by reference to the value of the pre-tax contribution account in his Profit Sharing Plan Account as of the Valuation Date immediately preceding the date of withdrawal. A Member who receives
such a hardship withdrawal shall be prohibited from making Pre-Tax Contributions under the Plan or pre-tax contributions under any other cash or deferred arrangement for the twelve (12) consecutive months following the date of distribution and
in addition, the dollar limitation on the Pre-Tax Contributions described in Section 4.1 shall be reduced in the year following the hardship withdrawal by the amount of Pre-Tax Contributions made by the Member in the Plan Year during which the
withdrawal was made. The following standards (or such other standards as may be acceptable under Treasury Regulations issued pursuant to Section 401(k) of the Code) shall be applied on a uniform and non-discriminatory basis in determining the
existence of such a hardship: 
  
 (a) A financial
need shall be considered immediate if it must be satisfied in substantial part within a period of twelve (12) months from the date on which the Member certifies his eligibility for a hardship withdrawal. A financial need shall be considered
substantial if it exceeds ten percent (10%) of the Member’s annual Compensation. 
  
 (b) Subject to the provisions of Section 6.1(a) above, a distribution will be deemed by the Committee to be on account of an
immediate and substantial financial need if it results from: 
  
 (i) medical expenses incurred by the Member, or the Member’s spouse or dependents (as defined in Section 152 of the Code), 
  
 (ii) purchase (excluding mortgage payments) of a principal residence for the Member, 
  

 24 

 (iii) payment for tuition for the next semester or quarter of post-secondary education
for the Member or the Member’s spouse, children or dependents, or 
  
 (iv) the need to prevent the eviction of the Member from his principal residence or foreclosure on the mortgage of the Member’s principal residence. 
  
 6.2 Withdrawals of Amounts From After-Tax Contribution Account: Each Member of the Plan, upon giving written notice
to the Committee (in such form and in such manner as prescribed by the Committee), may elect to withdraw from his After-Tax Contribution Account those contributions which are made on or after January 1, 1991. The minimum amount of such
withdrawal shall be $500. If a withdrawal is made to a Member before he attains age 59- 1/2, the Member shall be
advised by the Committee that in addition to taxes payable on investment earnings, an income tax may be imposed equal to ten percent (10%) of the amount so received which is included in his gross income for such taxable year. 

 
 6.3 Withdrawals of Amounts From Pre-Tax Account: A Member may
not withdraw any amount from his Pre-Tax Account, except a Member who has attained age 59- 1/2 may elect,
by giving sixty (60) days’ written notice to the Committee (or within any other period of time as prescribed by the Committee) and by following such other rules and procedures as may be prescribed from time to time by the Committee on a
uniform and non-discriminatory basis, to withdraw the entire amount or any portion of his Pre-Tax Contribution Account. 
  
 6.4 Withdrawals from Employer Contribution, ESOP and Rollover Accounts: A Member may not withdraw any amount from his Employer Contribution,
ESOP or Rollover Accounts. 
  
 6.5 Loans to Members: Except
as provided below, the availability of loans are limited to Members who are Employees (hereinafter “Borrowers”), who may make application to the Committee to borrow from the Accounts maintained by or for the Borrower in the Trust Fund.
Additionally, in order for the exemption set forth in 29 C.F.R. 2550.408b-1 to apply to the Plan, a Borrower may also include, but only to the extent not resulting in discrimination prohibited by Section 401(a)(4) of the Code, any other Member
or Beneficiary who is a “party in interest” with respect to the Plan within the meaning of ERISA Section 3(14). It is within the sole discretion of the Committee whether or not to permit such a loan. Loans shall be granted in a
uniform and non-discriminatory manner on terms and conditions determined by the Committee which shall not result in more favorable treatment of highly compensated employees and shall be set forth in written procedures promulgated by the Committee in
accordance with applicable governmental regulations. All such loans shall also be subject to the following terms and conditions: 
  
 (a) The amount of the loan, when added to the amount of any outstanding loan or loans to the Borrower from any other plan of the Employer
or an Affiliate which is qualified under Section 401(a) of the Code, shall not exceed the lesser of (i) $50,000, reduced by the excess, if any, of the highest outstanding 

  

 25 

 
balance of loans from all such plans during the one-year period ending on the day before the date on which such loan was made over the outstanding balance of
loans from the Plan on the date on which such loan was made or (ii) fifty percent (50%) of the present value of the Borrower’s vested Account balance under the Plan. In no event shall a loan of less than $1,000 be made to a Borrower.
A Borrower may not have more than one (1) loan outstanding at a time under this Plan, and a Borrower will be limited to a maximum of one (1) loan per year from this Plan. 
  
 (b) The loan shall be for a term not to exceed five (5) years, and shall be evidenced by a note signed
by the Borrower. The loan shall be payable in periodic installments and shall bear interest at a reasonable rate which shall be determined by the Committee on a uniform and consistent basis and set forth in the procedures in accordance with
applicable governmental regulations. Payments by a Borrower who is an Employee will be made by means of payroll deduction from the Borrower’s compensation. If a Borrower is not receiving compensation from the Employer, the loan repayment shall
be made in accordance with the terms and procedures established by the Committee. A Borrower may repay an outstanding loan in full at any time. 
  
 (c) In the event an installment payment is not paid within seven (7) days following the monthly due date, the Committee shall give
written notice to the Borrower sent to his last known address. If such installment payment is not made within thirty (30) days thereafter, the Committee shall proceed with foreclosure in order to collect the full remaining loan balance or shall
make such other arrangements with the Borrower as the Committee deems appropriate. Foreclosure need not be effected until occurrence of a distributable event under the terms of the Plan and no rights against the Borrower or the security shall be
deemed waived by the Plan as a result of such delay. 
  
 (d) The unpaid balance of the loan, together with interest thereon, shall become due and payable upon the date of distribution of the Account and the Trustee shall first satisfy the indebtedness from the amount payable to the Borrower or to
the Borrower’s Beneficiary before making any payments to the Borrower or to the Borrower’s Beneficiary. 
  
 (e) Any loan to a Borrower under the Plan shall be adequately secured. Such security may include a pledge of a portion of the
Borrower’s right, title and interest in the Trust Fund which shall not exceed fifty percent (50%) of the present value of the Borrower’s vested Account balance under the Plan as determined immediately after the loan is extended. Such
pledge shall be evidenced by the execution of a promissory note by the Borrower which shall grant the security interest and provide that, in the event of any default by the Borrower on a loan repayment, the Committee shall be authorized to take any
and all appropriate lawful actions necessary to enforce collection of the unpaid loan. 
  
 (f) A request by a Borrower for a loan shall be made in writing to the Committee and shall specify the amount of the loan. If a
Borrower’s request for a loan is approved by the Committee, the Committee shall furnish the Trustee with written instructions directing the Trustee to make the loan in a lump-sum payment of cash to the Borrower. The cash for such payment shall
be obtained by redeeming proportionately as of the date of payment the Investment Fund or Investment Funds, or portions thereof, that are credited to the particular Account of such Borrower. 
  
 (g) A loan to a Borrower shall be considered an investment
of the separate Account(s) of the Borrower from which the loan is made. All loan repayments shall be credited pro rata to such separate Account(s) and reinvested exclusively in shares of one or more of the Investment Funds in accordance with the
Borrower’s most recent investment direction made in accordance with Section 9.3.

 MEMBERS’ BENEFITS 
  
 7.1 Retirement of Members on or after Retirement Date: Any Member who terminates his Service on or after his Retirement Date shall have a fully

 7.2 Disability of Members: If the Committee shall find and advise the
Trustee that Service of a Member has been terminated because of Total and Permanent Disability, which in the judgment of the Committee, based upon advice of competent physicians of their selection, will prevent such Member from resuming his Service
with an Employer, such Member shall become entitled to receive the entire amount of his Account. The “entire amount” in such Member’s Account shall include any Savings Contributions, Rollover Amounts, amounts in the Profit Sharing
Plan Account, ESOP Account and Employer Contributions to be made as of the Valuation Date preceding his termination of Service. Payment of benefits due under this Section shall be made in accordance with Section 8.1.

with Section 8.1. 
  
 In addition, any amounts forfeited from
the prior Employer Contribution Account of such Member upon his earlier termination of Service shall be reinstated to his new Employer Contribution Account. Upon the re-employment of any individual who had previously been a Member and who has
incurred five consecutive Breaks In Service, such re-employed individual shall not be entitled to a reinstatement of any Forfeiture incurred by reason of his prior termination of employment. 
  
 If a distribution is made at a time when a Member is not fully vested in his
Employer Contribution Account balance, and if the Member is re-employed prior to a Forfeiture of the balance of his Employer Contribution Account, the Member’s non-forfeitable portion of the balance of the undistributed Employer Contribution
Account shall be reinstated to his new Employer Account (as provided in Section 4.8) within a reasonable time after repayment by the Member of the amount of his previous distribution, if any. 
  
 Notwithstanding anything herein to the contrary, if a Member
(i) terminates Service prior to having completed five years of Vesting Service; (ii) meets the eligibility requirements for a severance plan approved by the Chief Executive Officer of the Company and the Committee and listed on Appendix A
attached hereto; and (iii) if required by the applicable severance plan, signs a waiver and release, such Member shall be entitled to receive the entire amount credited to such Member’s Employer Contribution Account. 
  
 7.5 Valuation Dates Determinative of Member’s Rights: The amount
to which a Member is entitled upon his retirement, disability, death or other termination of Service shall be valued as of the Valuation Date determined as follows: 
  
 (a) In the case of any Member whose Service is terminated due to his retirement on or after his Retirement
Date, disability or death, the amount to which such Member or his Beneficiary is entitled upon such termination of Service shall be determined as of the last Valuation Date preceding his termination of Service. 
  
 (b) In the case of any Member whose Service is terminated
for any reason other than retirement on or after his Retirement Date, disability or death, the amount to which such Member is entitled upon such termination of Service shall be valued as of the last Valuation Date preceding the Distribution Date as
defined in Section 8.1. 
  
 7.6 Vesting for Certain

 ARTICLE VIII 
  
 PAYMENT OF BENEFITS 
  
 8.1 Payment of Benefits: Upon a Member’s entitlement to payment of benefits under Section 7.1, 7.2 or 7.4, he shall file with the
Committee his written election on such forms or forms, and subject to such conditions, as the Committee shall provide. Such benefit may be made in two distributions, the first such distribution consisting of the entire amount in such Member’s
Account as of the Valuation Date preceding his termination of Service plus any Pre-Tax or After-Tax Contributions made by the Member subsequent to such Valuation Date, and the second distribution consisting of the Employer Contribution allocated to
such Member’s Account as of the Valuation Date of the Plan Year in which such Member terminated Service. The Committee shall direct the Trustee to distribute the Member’s benefits according to the Member’s election. 
  
 The day following the date of the Member’s termination of Service is the
earliest date that payment of his benefits may commence and is herein referred to as such Member’s “Distribution Date.” Payment of a Member’s benefits shall be made or commence as soon as practicable after his Distribution Date,
subject to the Member’s election to defer receipt thereof, but in any event must be made or commence prior to the expiration of 60 days after the Valuation Date of the Plan Year within which such Member’s Retirement Date occurs or the
date of his death, if earlier. A member who withholds consent to an immediate distribution may at any time, subsequently elect, in the form and manner prescribed by the Committee, to receive payment of benefits. If a benefit distribution under the
Plan is made to a Member before he attains age 59- 1/2, the Member shall be advised by the Committee that an
additional income tax may be imposed equal to ten percent (10%) of the portion of the amount so received which is included in his gross income for such taxable year and which is attributable to benefits accrued while he was a Member. Members
who terminate Service after attainment of age fifty-five (55) shall be notified of their exemption from said additional tax. 
  
 The amount which a Member, former Member or Beneficiary is entitled to receive at any time and from time to time shall be paid in cash as a lump sum,
except amounts payable to or on behalf of Members who have shares of Cabot Corporation stock or shares of Cabot Oil and Gas Corporation stock in their Profit Sharing Plan Account or their ESOP Account may have their stock balance paid in cash or as
stock certificates adjusted to reflect commission fees. The Profit Sharing Plan Account and the ESOP Account shall retain the payment options provided under the Profit Sharing Plan and the ESOP. 
  
 If the amount to which a terminated Member is entitled is not more than
$5,000, such amount shall be paid to the Member as soon as practicable after his Distribution Date; if such amount is in excess of $5,000, the distribution shall be made only if the Member so consents. If such consent is withheld, distribution of
the amount to which the terminated Member is entitled shall be made to such Member within 60 days after the end of the Plan Year in which occurs the earlier of the Member’s death or his Retirement Date. If a Member’s termination of Service
occurs after his Retirement Date, distribution shall be made within 60 days after the end of the Plan Year in which termination occurs. If a Member dies before 

  

 29 

 
distribution of his interest commences, the Member’s entire interest will be distributed no later than five years after the Member’s death. If
distribution has commenced before the Member’s death, any remaining amount in the Member’s Account shall be distributed at least as rapidly as under the method of distribution being used as of the date of the Member’s death.

  
 Notwithstanding anything herein to the contrary, if a
distribution is one to which Code Sections 401(a)(11) and 417 do not apply, such distribution may commence less than 30 days after the notice required under Section 1.411(a)-11(c) of the Income Tax Regulations is given, provided that
(a) the Committee clearly informs the Member that the Member has a right to a period of at least 30 days after receiving the notice to consider the decision of whether or not to elect a distribution (and, if applicable, a particular
distribution option), and (b) the Member, after receiving the notice, affirmatively elects a distribution. If a distribution is one to which Sections 401(a)(11) and 417 of the Code does apply, the Member may elect, with the consent of the
Member’s spouse to waive any requirement that the written explanation required under Code Section 417 be provided at least 30 days before the annuity starting date (or to waive the 30-day requirement with respect to an explanation provided
after the annuity starting date) if the distribution commences more than 7 days after such explanation is provided. 
  
 8.2 Distribution Upon Death: In the event of the death of any Member, the amount in his Account shall be distributable as follows: 
  
 (a) A Member shall file with the Committee a written
designation, in the form prescribed by the Committee, of the Beneficiary or Beneficiaries to receive the amount in his Account upon his death, and the Member may at any time change or cancel any such designation by filing a written request in the
form prescribed by the Committee. No such designation of Beneficiary shall be effective if the Member has a spouse, unless the spouse is designated as the Beneficiary or unless the spouse consents to the designation of another person as Beneficiary
or the absence of the spouse’s consent is permitted herein. The Member’s spouse may waive the right to be the Member’s sole Beneficiary and consent to the Beneficiary designation made by the Member. The waiver must (i) be in
writing; (ii) designate a specific alternate Beneficiary and a form of benefit which may not be changed without spousal consent (or must expressly permit designation by the Member without further consent of the spouse); (iii) acknowledge
the effect of the waiver; and (iv) be witnessed by a Plan representative or a notary public. The spouse’s consent to a Beneficiary designation shall not be required if it is established to the satisfaction of the Committee that such
written consent may not be obtained because there is no spouse or the spouse cannot be located. Any consent under this Section 8.2(a) will be valid only with respect to the spouse who signs the consent. Additionally, a revocation of a prior
spousal consent may be made by a Member without the consent of the spouse at any time before the distribution of the benefit under the Plan. The number of revocations shall not be limited. 
  
 (b) In the event of the death of any Member, the entire
amount in the Account of such Member shall be distributed to the Member’s spouse, or if there 

  

 30 

 
is no spouse, or the spouse has consented pursuant to Section 8.2(a), then to the Beneficiary designated by him as provided in the preceding
paragraph (a); or, in the absence of an effective designation or if no designated Beneficiary survives the Member, then to the duly appointed and qualified executor or administrator of the Member’s estate; or, if no administration of the
estate of such decedent is necessary, then to the Beneficiary entitled thereto under the last will and testament of such deceased Member; or, if such decedent left no will, to the legal heirs of such decedent determined in accordance with the laws
of intestate succession of the state of the decedent’s domicile. 
  
 (c) If the Committee shall be in doubt as to the right of any Beneficiary designated by a deceased Member to take the interest of such decedent, the Committee may direct the Trustee to distribute the amount in the
Account in question to the estate of such Member, in which event the Trustee, the Employer, the Committee, and any other person in any manner connected with the Plan, shall have no further liability in respect of the assets. 
  
 8.3 Required Minimum Distributions: Except as provided below, if a
Member is employed by the Company on the April 1 following the calendar year in which the Member attains age 70- 1/2 such Member may choose to commence distribution of any benefits to which the Member is entitled either on the April 1 of the calendar year following the calendar year in which (i) the Member attains age 70- 1/2 or (ii) the Member retires from the Company. Notwithstanding any provision of the Plan to the contrary, any
benefits to which a member who is a 5% owner of the Company is entitled shall commence not later than April 1 of the calendar year following the calendar year in which the Member attains age 70- 1/2, whether or not his employment has terminated in such year. Such distribution shall be at least equal to the required minimum distributions under
Section 401(a)(9) of the Code and the regulations thereunder. With respect to distributions under the Plan made for calendar years beginning on or after January 1, 2001, the Plan will apply the minimum distribution requirements of
Section 401(a)(9) of the Code in accordance with the regulations under Section 401(a)(9) that were proposed on January 17, 2001, notwithstanding any provision of the Plan to the contrary. This amendment shall continue in effect until
the end of the last calendar year beginning before the effective date of final regulations under Section 401(a)(9) or such other date as may be specified in guidance published by the Internal Revenue Service. 
  
 8.4 Disputed Benefits: If any dispute still exists between a Member or
a Beneficiary and the Committee after a review of the claim or in the event any uncertainty shall develop as to the person to whom payment of any benefit hereunder shall be made, the Trustee may withhold the payment of all or any part of the
benefits payable hereunder to the Member or Beneficiary until such dispute has been resolved by a court of competent jurisdiction or settled by the parties involved. 
  
 8.5 Member’s Right to Transfer Eligible Rollover Distribution: 
  
 A. Rule: Notwithstanding any provision of the Plan to the contrary
that would otherwise limit a distributee’s election under this Section, a distributee may elect, at the 

  

 31 

 
time and in the manner prescribed by the plan administrator, to have any portion of an eligible rollover distribution paid directly to an eligible retirement
plan specified by the distributee in a direct rollover. 
  
 B.
Definitions: 
  
 (a) Eligible Rollover
Distribution: An eligible rollover distribution is any distribution of all or any portion of the balance to the credit of the distributee, except that an eligible rollover distribution does not include: any distribution that is one of a
series of substantially equal periodic payments (not less frequently than annually) made for the life (or life expectancy) of the distributee or the joint lives (or joint life expectancies) of the distributee and the distributee’s designated
beneficiary, or for a specified period of ten (10) years or more; any distribution to the extent such distribution is required under Section 401(a)(9) of the Code; any hardship withdrawal described in Section 401(k)(2)(B)(i)(IV) of
the Code; and the portion of any distribution that is not includable in gross income (determined without regard to the exclusion for net unrealized appreciation with respect to employer securities). 
  
 (b) Eligible Retirement Plan: An eligible
retirement plan is an individual retirement account described in Section 408(a) of the Code, an individual retirement annuity described in Section 408(b) of the Code, an annuity plan described in Section 403(a) of the Code, or a
qualified trust described in Section 401(a) of the Code, that accepts the distributee’s eligible rollover distribution. However, in the case of an eligible rollover distribution to the surviving spouse, an eligible retirement plan is an
individual retirement account or individual retirement annuity. 
  
 (c) Distributee: A distributee includes an Employee or former Employee. In addition, the Employee’s or former Employee’s surviving spouse and the Employee’s or former Employee’s spouse
or former spouse who is the alternate payee under a qualified domestic relations order, as defined in Section 414(p) of the Code, are distributees with regard to the interest of the spouse or former spouse. 
  
 (d) Direct Rollover: A direct rollover is a
payment by the Plan to the eligible retirement plan specified by the distributee.

provisions of Section 9.2, and, not by way of limitation, the provisions of the Trust Agreement, the Trustee may invest a portion of the Trust Fund in common stock of the Company, or in any other “qualifying employer security” within
the meaning of Section 407(d)(5) of ERISA.

Investment Funds pursuant to the directions of the Members given in accordance with the provisions of Sections 9.3 and 9.4 as certified to the Trustee by the Committee. Except as otherwise provided herein, interest, dividends and other income
and all profits and gains produced by each such Investment Fund shall be paid into such Investment Fund, and such interest, dividends and other income or profits and gains, without distinction between principal and income, may be invested and
reinvested but only in the property hereinabove specified for the particular Investment Fund. Notwithstanding any provision in this Section to the contrary, the Committee may direct the Trustee (i) to invest Savings or Employer Contributions in
short-term fixed income investments which are acceptable to the Trustee or in the suspense account to be maintained in each Investment Fund during the period from the date of any such Contribution until the next Valuation Date or (ii) to invest
all or any portion of the Trust Fund attributable to any terminated or retired Member or attributable to any Member who is expected to retire or to terminate his Service within one (1) year, in one or more fixed income investments which are
acceptable to the Trustee. The fixed income investments authorized by this Section shall include, but not be limited to, certificates of deposit, savings accounts, or U.S. Treasury bills or notes. 
  
 9.3 Investment Directions of Members: Each Member may, in a form and
manner prescribed by the Committee, direct that the total of the Contributions allocable to his Pre-Tax and After-Tax Contribution Accounts, Employer Contribution Account, Profit Sharing Plan Account and Rollover Account, if any, and the earnings
and accretions thereon, be invested in such percentages (in increments of ten percent (10%) of the total of all Accounts) as he may designate among the Investment Funds. In the event a Member fails to direct the manner of investing his
Accounts as provided herein, his Accounts shall be invested only in the Money Market Fund. 
  
 9.4 Change of Investment Directions: Each Member may, in the manner prescribed by the Committee and subject to any restrictions or conditions which may be established by the Committee, authorize the transfer of
existing account balances twelve (12) times each Plan Year 
  

 33 

 
among the available Investment Funds (in ten percent (10%) increments). Notwithstanding the foregoing, a Member may authorize the transfer of his
existing account balances to the Money Market Fund at any time, in a manner prescribed by the Committee and subject to the Committee’s consent and any other restrictions or conditions which may be established by the Committee. 
  
 Each Member may, in a form and manner prescribed by the Committee and subject
to any restrictions or conditions which may be established by the Committee, direct that the investment of his future Pre-Tax Contributions, After-Tax Contributions and Employer Contributions be changed from one Investment Fund to another.

  
 9.5 Benefits Paid Solely from Trust Fund: All of the
benefits provided to be paid under Article VIII shall be paid by the Trustee out of the Trust Fund to be administered under such Trust Agreement. No Fiduciary shall be responsible or liable in any manner for payment of any such benefits, and
all Members hereunder shall look solely to such Trust Fund and to the adequacy thereof for the payment of any such benefits of any nature or kind which may at any time be payable hereunder. 
  
 9.6 Committee Directions to Trustee: The Trustee shall make only such
distributions and payments out of the Trust Fund as may be directed by the Committee. The Trustee shall not be required to determine or make any investigation to determine the identity or mailing address of any person entitled to any distributions

 ARTICLE X 
  
 ADOPTION OF PLAN BY OTHER ORGANIZATIONS; 
 SEPARATION OF THE TRUST FUND; AMENDMENT 
 AND TERMINATION OF THE PLAN;  
 DISCONTINUANCE OF CONTRIBUTIONS TO THE TRUST FUND 
  
 10.1 Adoptive Instrument: Any corporation or other organization with employees, now in existence or hereafter formed or acquired which is not
already an Employer under this Plan and which is otherwise legally eligible, may, with the approval of the Company by action of the Board of Directors, adopt and become an Employer under this Plan by executing and delivering to the Company and the
Trustee an adoptive instrument specifying the classification of its Employees who are to be eligible to participate in the Plan and by agreeing to be bound as an Employer by all the terms of the Plan with respect to its eligible Employees. The
adoptive instrument may contain such changes and variations in the terms of the Plan as may be acceptable to the Company. Any such approved organizations which shall adopt this Plan shall designate the Company as its agent to act for it in all
transactions affecting the administration of the Plan and shall designate the Committee to act for such Employer and its Members in the same manner in which the Committee may act for the Company and its Members hereunder. The adoptive instrument
shall specify the effective date of such adoption of the Plan and shall become, as to such adopting Employer and its Employees, a part of this Plan. Such Employer shall also forthwith obtain a favorable determination letter from the appropriate
District Director of the Internal Revenue with respect to its participation in the Plan. The Company may, in its absolute discretion, terminate an adopting Employer’s participation at any time when in its judgment such adopting Employer fails
or refuses to discharge its obligations under the Plan. Unless otherwise specifically provided, in the event a corporation or organization that has adopted the Plan ceases to be an Affiliate of the Company its participation in the Plan shall
terminate. 
  
 10.2 Separation of the Trust Fund: A
separation of the Trust Fund as to the interest therein of the Members of any particular Employer may be made by an Employer at any time. In such event, the Trustee shall set apart that portion of the Trust Fund which shall be allocated to such
Members pursuant to a valuation and allocation of the Trust Fund made in accordance with the procedures set forth in Sections 5.2 and 5.4, but as of the date when such separation of the Trust Fund shall be effective. Such portion may in the
Trustee’s discretion be set apart in cash or in kind out of the properties of the Trust Fund. That portion of the Trust Fund so set apart shall continue to be held by the Trustee as though such Employer had entered into the Trust Agreement as a
separate trust agreement with the Trustee. Such Employer may in such event designate a new trustee of its selection to act as trustee under such separate trust agreement. Such Employer shall thereupon be deemed to have adopted the Plan as its own
separate plan, and shall subsequently have all such powers of amendment or modification of such plan as are reserved herein to the Company. 
  
 10.3 Voluntary Separation: If any Employer shall desire to separate its interest in the Trust Fund, it may request such a separation in a notice in
writing to the Company and the Trustee. Such separation shall then be made as of any specified date after service of such notice, and such separation shall be accomplished in the manner set forth in Section 10.2. 
  

 35 

 10.4 Amendment of the Plan: The Company shall have the right to amend or modify this Plan and
(with the consent of the Trustee) the Trust Agreement at any time and from time to time to any extent that it may deem advisable. Any such amendment or modification shall be set out in an instrument in writing duly authorized by the Board of
Directors and executed by the Company. No such amendment or modification shall, however, increase the duties or responsibilities of the Trustee without its consent thereto in writing, or have the effect of transferring to or vesting in any Employer
any interest or ownership in any properties of the Trust Fund, or of permitting the same to be used for or diverted to purposes other than for the exclusive benefit of the Members and their Beneficiaries. No such amendment shall decrease the Account
of any Member or shall decrease any Member’s vested interest in his Account. Notwithstanding anything herein to the contrary, the Plan or the Trust Agreement may be amended in such manner as may be required at any time to make it conform to the
requirements of the Internal Revenue Code or of any United States statutes with respect to employees’ trusts, or of any amendment thereto, or of any regulations or rulings issued pursuant thereto, and no such amendment shall be considered
prejudicial to any then existing rights of any Member or his Beneficiary under the Plan. 
  
 10.5 Acceptance or Rejection of Amendment by Employers: The Company shall promptly deliver to each other Employer any amendment to this Plan or the Trust Agreement. Each such Employer will be deemed to have
consented to such amendment unless it notifies the Company and the Trustee in writing within thirty (30) days after receipt of the amendment that it does not consent thereto, and requests a separation of its interest in the Trust Fund in
accordance with the provisions of Section 10.2, as of the first day of the month following such written notification to the Company and the Trustee. 
  
 10.6 Termination of the Plan: In accordance with the procedures set forth in this Section 10.6, the Company or any other Employer may effect a
termination of the Plan as to such particular Employer under the following circumstances: 
  
 (a) The Plan may be terminated by the delivery to the Trustee of an instrument in writing approved and authorized by the board of
directors of such Employer. In such event, termination of the Plan shall be effective as of any subsequent date specified in such instrument. 
  
 (b) Except as otherwise provided in Section 10.10, the Plan shall terminate effective at the expiration of sixty (60) days
following the merger into another corporation or dissolution of any Employer, or following any final legal adjudication of any Employer as a bankrupt or an insolvent, unless within such time a successor organization approved by the Company shall
deliver to the Trustee a written instrument certifying that such organization (i) has become the Employer of more than fifty percent (50%) of those Employees of such Employer who are then Members under this Plan and (ii) has adopted
the Plan as to its Employees. In any such event the interest in the Plan of any Member whose employment may not be continued by the successor shall be fully vested as of the date of termination of his Service, and shall be payable in cash or in kind
within six (6) months from the date of termination of his Service. 
  

 36 

 10.7 Liquidation and Distribution of Trust Fund Upon Termination: In the event a complete
termination of the Plan in respect of any Employer shall occur, a separation of the Trust Fund in respect of the affected Members of such Employer shall be made as of the effective date of such termination of the Plan in accordance with the
procedure set forth in Section 10.2. Following separation of the Trust Fund in respect of the Members of any Employer as to whom the Plan has been terminated, the assets and properties of the Trust Fund, so set apart, shall be reduced to cash
as soon as may be expeditious under the circumstances. Any administrative costs or expenses incurred incident to the final liquidation of such separate trust funds shall be paid by the Employer, except that in the case of bankruptcy or insolvency of
such Employer any such costs shall be charged against the Trust Fund. Following such partial reduction of such Trust Fund to cash, the Accounts of the Members shall then be valued as provided in Sections 5.2 and 5.4 and shall be fully vested,
whereupon each such Member shall become entitled to receive the entire amount in his Account in cash as directed by the Committee. The terminating Employer shall promptly advise the appropriate District Director of Internal Revenue of such complete
or partial termination and shall direct the Trustee to delay the final distribution to its affected Members until the District Director shall advise in writing that such termination does not adversely affect the previously qualified status of the
Plan or the exemption from tax of the Trust under Section 401(a) or 501(a) of the Code. 
  
 10.8 Effect of Termination or Discontinuance of Contributions: If any Employer shall terminate the Plan as to its Employees, then all amounts credited to the Accounts of the Members of such Employer with
respect to whom the Plan has terminated shall become fully vested and non-forfeitable. If any Employer shall completely discontinue its Contributions to the Trust Fund or suspend its Contributions to the Trust Fund under such circumstances as to
constitute a complete discontinuance of Contributions within the meaning of Section 1.401-6(c) of the regulations under the Code, then all amounts credited to the Accounts of the Members of such Employer shall become fully vested and
non-forfeitable, and throughout any such period of discontinuance of Contributions by an Employer all other provisions of the Plan shall continue in full force and effect with respect to such Employer other than the provisions for Contributions by
such Employer. 
  
 10.9 Merger of Plan with Another Plan:
In the event of any merger or consolidation of the Plan with, or transfer in whole or in part of the assets and liabilities of the Trust Fund to another trust fund held under, any other plan of deferred compensation maintained or to be established
for the benefit of all or some of the Members of this Plan, the assets of the Trust Fund applicable to such Members shall be transferred to the other trust fund only if: 
  
 (a) Each Member would (if either this Plan or the other plan then terminated) receive a benefit immediately
after the merger, consolidation or transfer which is equal to or greater than the benefit he would have been entitled to receive immediately before the merger, consolidation or transfer (if this Plan had then terminated); 
  

 37 

 (b) Resolutions of the board of directors of the Employer under this Plan, or of any new
or successor employer of the affected Members, shall authorize such transfer of assets, and, in the case of the new or successor employer of the affected Members, its resolutions shall include an assumption of liabilities with respect to such
Members’ inclusion in the new employer’s plan; and 
  
 (c) Such other plan and trust are qualified under Sections 401(a) and 501(a) of the Code. 
  
 10.10 Consolidation or Merger with Another Employer: Notwithstanding any provision of this Article X to the contrary, upon the consolidation
or merger of two or more Employers under this Plan with each other, the surviving Employer or organization shall automatically succeed to all the rights and duties under the Plan and Trust of the Employers involved, and their shares of the Trust
Fund shall, subject to the provisions of Section 10.9, be merged and thereafter be allocable to the surviving Employer or organization for its Employees and their Beneficiaries. 
  

 38 

 ARTICLE XI 
  
 MISCELLANEOUS PROVISIONS 
  
 11.1 Terms of Employment: The adoption and maintenance of the provisions of this Plan shall not be deemed to constitute a contract between any
Employer and Employee, or to be a consideration for, or an inducement or condition of, the employment of any person. Nothing herein contained shall be deemed to give to any Employee the right to be retained in the employ of an Employer or to
interfere with the right of an Employer to discharge an Employee at any time, nor shall it be deemed to give to an Employer the right to require any Employee to remain in its employ, nor shall it interfere with any Employee’s right to terminate
his employment at any time. 
  
 11.2 Controlling Law:
Subject to the provisions of ERISA, this Plan shall be construed, regulated and administered under the laws of the State of Texas. 
  
 11.3 Invalidity of Particular Provisions: In the event any provision of this Plan shall be held illegal or invalid for any reason, said illegality
or invalidity shall not affect the remaining provisions of this Plan but shall be fully severable, and this Plan shall be construed and enforced as if said illegal or invalid provisions had never been inserted herein. 
  
 11.4 Non-Alienation of Benefits: Except as otherwise provided below
and with respect to certain judgments and settlements pursuant to Section 401(a)(13) of the Code, no benefit which shall be payable out of the Trust Fund to any person (including a Member or Beneficiary) shall be subject in any manner to
anticipation, alienation, sale, transfer, assignment, pledge, encumbrance or charge, and any attempt to anticipate, alienate, sell, transfer, assign, pledge, encumber or charge the same shall be void; and no such benefit shall in any manner be
liable for, or subject to, the death, contracts, liabilities, engagements or torts of any person, and the same shall not be recognized by the Trustee, except to the extent as may be required by law. 
  
 This provision shall not apply to a “qualified domestic relations
order” defined in Code Section 414(p), and those other domestic relations orders permitted to be so treated by the Administrator under the provisions of the Retirement Equity Act of 1984. To the extent provided under a “qualified
domestic relations order,” a former spouse of a Member shall be treated as the spouse or surviving spouse for all purposes of the Plan. If the Committee receives a qualified domestic relations order with respect to a Member, the Committee may
authorize the immediate distribution of the amount assigned to the Member’s former spouse, to the extent permitted by law, from the Member’s Accounts. 
  

11.5 Payments in Satisfaction of Claims of Members: Any payment or distribution to any Member or his legal representative or any Beneficiary in
accordance with the provisions of this Plan shall be in full satisfaction of all claims under the Plan against the Trust Fund, the Trustee and the Employer. The Trustee may require that any distributee execute and deliver to the Trustee a receipt
and a full and complete release as a condition precedent to any payment or distribution under the Plan. 
  

 39 

 11.6 Payments Due Minors and Incompetents: If the Committee determines that any person to whom a
payment is due hereunder is a minor or is incompetent by reason of physical or mental disability, the Committee shall have the power to cause the payments becoming due such person to be made to another for the benefit of such minor or incompetent,
without the Committee or the Trustee being responsible to see to the application of such payment. To the extent permitted by ERISA, payments made pursuant to such power shall operate as a complete discharge of the Committee, the Trustee and the
Employer. 
  
 11.7 Impossibility of Diversion of Trust
Fund: Notwithstanding any provision herein to the contrary, no part of the corpus or the income of the Trust Fund shall ever be used for or diverted to purposes other than for the exclusive benefit of the Member or their Beneficiaries or for the
payment of expenses of the Plan. No part of the Trust Fund shall ever directly or indirectly revert to any Employer. 
  
 11.8 Evidence Furnished Conclusive: The Employer, the Committee and any person involved in the administration of the Plan or management of the
Trust Fund shall be entitled to rely upon any certification, statement, or representation made or evidence furnished by a Member or Beneficiary with respect to facts required to be determined under any of the provisions of the Plan, and shall not be
liable on account of the payment of any monies or the doing of any act or failure to act in reliance thereon. Any such certification, statement, representation, or evidence, upon being duly made or furnished, shall be conclusively binding upon such
Member or Beneficiary but not upon the Employer, the Member or any other person involved in the administration of the Plan or management of the Trust Fund. Nothing herein contained shall be construed to prevent any of such parties from contesting
any such certification, statement, representation, or evidence or to relieve the Member or Beneficiary from the duty of submitting satisfactory proof of such fact. 
  
 11.9 Copy Available to Members: A copy of the Plan, and of any and all future amendments thereto, shall be provided
to the Committee and shall be available to Members and, in the event of the death of a Member, to his Beneficiary, for inspection at the offices of his Employer during the regular office hours of the Employer. 
  
 11.10 Unclaimed Benefits: If at, after or during the time when a
benefit hereunder is payable to any Member, Beneficiary or other distributee, the Committee, upon request of the Trustee, or at its own instance, shall mail by registered or certified mail to such Member, Beneficiary or other distributee at his last
known address a written demand for his then address or for satisfactory evidence of his continued life, or both, and if such Member, Beneficiary or distributee shall fail to furnish the same to the Committee within two (2) years from the
mailing of such demand, then the Committee may, in its sole discretion, determine that such Member, Beneficiary or other distributee has forfeited his right to such benefit and may declare such benefit, or any unpaid portion thereof, terminated as
if the death of the distributee (with no surviving Beneficiary) had occurred on the date of the last payment made thereon, or on the date such Member, Beneficiary or distributee first became entitled to receive benefit payments, whichever is later;
provided, however, that such forfeited benefit shall be reinstated if a claim for the same is made by the Member, Beneficiary or other distributee at any time thereafter. Such reinstatement shall be made out of the funds otherwise available for
allocation as Forfeitures for the Plan Year during which such claim was filed with the Committee (as provided in Section 4.8); and, if Forfeitures for the Plan Year are insufficient to reinstate such amounts, the Employer shall make the
Employer Minimum Contribution required under Section 4.2 hereof. 
  
 11.11 Headings for Convenience Only: The headings and subheadings herein are inserted for convenience of reference only and are not to be used in construing this instrument or any provision thereof.

 ARTICLE XII 
  
 LIMITATION ON BENEFITS 
  
 Notwithstanding any provision of this Plan to the contrary, the total Annual Additions made to the Account of a Member for any Plan Year shall be subject
to the following limitations: 
  
 I. Single Defined
Contribution Plan 
  
 1. If an Employer does
not maintain any other qualified plan, the amount of Annual Additions which may be allocated under this Plan on a Member’s behalf for a Limitation Year shall not exceed the lesser of the Maximum Permissible Amount or any other limitation
contained in this Plan. 
  
 2. Prior to the
determination of the Member’s actual Compensation for a Limitation Year, the Maximum Permissible Amount may be determined on the basis of the Member’s estimated annual Compensation for such Limitation Year. Such estimated annual
Compensation shall be determined on a reasonable basis and shall be uniformly determined for all Members similarly situated. Any Employer contributions (including allocation of forfeitures) based on estimated annual Compensation shall be reduced by
any Excess Amounts carried over from prior years. 
  
 3. As soon as is administratively feasible after the end of the Limitation Year, the Maximum Permissible Amount for such Limitation Year shall be determined on the basis of the Member’s actual Compensation for such Limitation Year.

  
 4. If there is an Excess Amount with respect
to a Member for the Limitation Year, any non-deductible voluntary employee contributions, to the extent they would reduce the Excess Amount, will be returned to the Member. Then, Excess Amounts will be treated as a Forfeiture and shall be applied as
a credit to subsequent Employer Contributions or reallocated to other Members to the extent such allocations do not exceed the Maximum Permissible Amount all as provided in Section 12(III)(4). Any Excess Amounts that cannot be allocated will be
held in a suspense account. All amounts in the suspense account must be allocated and reallocated to the Member’s accounts (subject to the limitations of Section 415) in succeeding Limitation Years before any Employer contribution and
non-deductible Employee contribution which would constitute Annual Additions may be made to the Plan. 
  
 If a suspense account is in existence at any time during the Limitation Year pursuant to this Section, it will not participate in the allocation of the
Trust’s investment gains and losses. 
  

 41 

 II. Two or More Defined Contribution Plans 
  
 1. If, in addition to this Plan, the Employer maintains any
other qualified defined contribution plan, the amount of Annual Additions which may be allocated under this Plan on a Member’s behalf for a Limitation Year, shall not exceed the lesser of: 
  
 A. the Maximum Permissible Amount, reduced by the sum of any
Annual Additions allocated to the Member’s accounts for the same Limitation Year under such other defined contribution plan or plans; or 
  
 B. any other limitation contained in this Plan. 
  

2. Prior to the determination of the Member’s actual Compensation for the Limitation Year, the amount referred to in
Section 1(A) above, may be determined on the basis of the Member’s estimated annual Compensation for such Limitation Year. Such estimated annual Compensation shall be determined on a reasonable basis and shall be uniformly determined for
all Members similarly situated. Any Employer contribution (including allocation of forfeitures) based on estimated annual Compensation shall be reduced by any Excess Amounts carried over from prior years. 
  
 3. As soon as is administratively feasible after the end of
the Limitation Year, the amounts referred to in Section 1(A) above shall be determined on the basis of the Member’s actual Compensation for such Limitation Year. 
  
 4. If a Member’s Annual Additions under this Plan and all such other defined contribution plans result
in an Excess Amount, such Excess Amount shall be deemed to consist of the amounts last allocated. 
  
 5. If an Excess Amount was allocated to a Member on an allocation date of this Plan which coincides with an allocation date of another
plan, the Excess Amount attributed to this Plan will be the product of: 
  
 A. the total Excess Amount allocated as of such date (including any amount which would have been allocated but for the limitations of Section 415 of the Code); times 
  
 B. the ratio of (1) the amount allocated to the Member
as of such date under this Plan, divided by (2) the total amount allocated as of such date under all qualified defined contribution plans (determined without regard to the limitations of Section 415 of the Code). 
  
 6. Any Excess Amounts attributed to this Plan shall be
disposed of as provided in Section 12(I)(4). 
  

 42 

 III. Definitions 
  
 1. Employer: The Company and any other Employer that adopts this Plan. In the case of a group of
employers which constitutes a controlled group of corporations (as defined in Code Section 414(b) as modified by Section 415(h)) or which constitutes trades and businesses (whether or not incorporated) which are under common control (as
defined in Code Section 414(c) as modified by Section 415(h)) or an affiliated service group (as defined in Code Section 414(m)), all such employers shall be considered a single Employer for purposes of applying the limitations of
these sections. 
  
 2. Excess Amount: The
excess of the Member’s Annual Additions for the Limitation Year over the Maximum Permissible Amount. 
  
 3. Limitation Year: The Plan Year. 
  
 4. Maximum Permissible Amount: For a Limitation Year, the Maximum Permissible Amount with respect to any Member shall be the lesser
of: 
  
 A. $35,000 as adjusted by the Secretary
of the Treasury or his delegate, or 
  
 B. 25% of
the Member’s Compensation for the Limitation Year. 
  
 5. Compensation: For purposes of determining compliance with the limitations of Code Section 415, Compensation shall mean a Member’s earned income, wages, salaries, fees for professional services and
other amounts received for personal services actually rendered in the course of employment with an Employer maintaining the Plan, including, but not limited to, commissions paid salesmen, compensation for services based on a percentage of profits,
commissions on insurance premiums, tips and bonuses and excluding the following: 
  
 (a) Employer contributions to a plan of a deferred compensation to the extent contributions are not included in gross income of the
Employee for the taxable year in which contributed, or on behalf of an employee to a simplified employee pension plan to the extent such contributions are deductible under Code Section 219(b)(2), and any distributions from a plan of deferred
compensation whether or not includable in the gross income of the Employee when distributed (however, any amounts received by an Employee pursuant to an unfunded non-qualified plan may be considered as compensation in the year such amounts are
included in the gross income of the Employee); 
  

 43 

 (b) amounts realized from the exercise of a non-qualified stock option, or when
restricted stock (or property) held by an employee becomes freely transferable or is no longer subject to a substantial risk of forfeiture; 
  
 (c) amounts realized from the sale, exchange or other disposition of stock acquired under a qualified stock option; and 
  
 (d) other amounts which receive special tax benefits, or
contributions made by an Employer (whether or not under a salary reduction agreement) towards the purchase of an annuity contract described in Code Section 403(b) (whether or not the contributions are excludable from the gross income of the
Employee). 
  
 For purposes of applying the limitations in this
Article, amounts included as compensation are those actually paid or made available to a Member within the Limitation Year. For Limitation Years beginning after December 31, 1994, Compensation shall be limited to $170,000 (unless adjusted in
the same manner as permitted under Code Section 415(d)). Notwithstanding anything to the contrary in this definition, Compensation shall include any and all items which may be included in Compensation under Code Section 415(c)(3),
including (i) any elective deferral (as defined in Code Section 402(g)(3) and (ii) any amount which is contributed or deferred by the Employer at the election of the Employee and which is not includible in the gross income of the
Employee by reason of Code Section 125, 132(f)(4) or 457. 
  
 6. Average Compensation: The average Compensation during a Member’s high three (3) years of service, which period is the three (3) consecutive calendar years (or, the actual number of consecutive
years of employment for those employees who are employed for less than three (3) consecutive years with the Employer) during which the Employee had the greatest aggregate Compensation from the Employer. 
  
 7. Annual Benefit: A benefit payable annually in the
form of a straight life annuity (with no ancillary benefits) under a plan to which Employees do not contribute and under which no rollover contributions are made. 
  
 8. Annual Additions: With respect to each Limitation Year, the total of the Employer Contributions,
Pre-Tax Contributions, After-Tax Contributions, Forfeitures, and amounts described in Code Sections 415(l) and 419A(d)(2) which are allocated to a Member’s Account. 
  

 44 

 ARTICLE XIII 
  
 TOP-HEAVY PLAN REQUIREMENTS 
  
 13.1 General Rule: For any Plan Year for which this Plan is a Top-Heavy Plan, as defined in Section 13.7, despite any other provisions of this
Plan to the contrary, this Plan shall be subject to the provisions of this Article XIII. 
  
 13.2 Vesting Provisions: Each Member who has completed an Hour of Service after the Plan becomes top-heavy and while the Plan is top-heavy and who has completed the Vesting Service specified in the following
table shall be vested in his account under this Plan at least as rapidly as is provided in the following schedule: 
  

				
	 Vesting Service

	  	Vested
Percentage

	 
	 Less than 2 years
	  	0	%
	 2 but less than 3 years
	  	20	%
	 3 but less than 4 years
	  	40	%
	 4 but less than 5 years
	  	60	%
	 5 but less than 6 years
	  	80	%
	 6 years or more
	  	100	%

  
 If an account becomes vested by reason
of the application of the preceding schedule, it may not thereafter be forfeited by reason of re-employment after retirement pursuant to a suspension of benefits provision, by reason of withdrawal of any mandatory employee contributions to which
employer contributions were keyed, or for any other reason. If the Plan subsequently ceases to be top-heavy, the preceding schedule shall continue to apply with respect to any Member who had at least three (3) years of service (as defined in
Treasury Regulation Section 1.411(a)-8T(b)(3)) as of the close of the last year that the Plan was top-heavy. For all other Members, the vested percentage provided in the preceding schedule prior to the date the Plan ceases to be top-heavy shall
not be reduced. 
  
 13.3 Minimum Contribution Provisions:
Each Member who (i) is a Non-Key Employee, as defined in Section 13.7 and (ii) is employed on the last day of the Plan Year will be entitled to have contributions and forfeitures allocated to his account of not less than three percent
(3%) (the “Minimum Contribution Percentage”) of the Member’s Compensation. This minimum allocation shall be provided without taking Pre-Tax Contributions into account. A Non-Key Employee may not fail to receive a Minimum
Contribution Percentage because of a failure to receive a specified minimum amount of compensation or a failure to make mandatory employee or elective contributions. This Minimum Contribution Percentage will be reduced for any Plan Year to the
percentage at which contributions (including Forfeitures) are made or are required to be made under the Plan for the Plan Year for the Key Employee for whom such percentage is the highest for such Plan Year. For this purpose, the percentage with
respect to a Key Employee will be determined by dividing the contributions (including Forfeitures) made for such Key Employee by his total compensation (as defined in Section 415 of the Code) not in excess of $200,000 for the Plan Year.

  

 45 

 Such amount will be adjusted in the same manner as the amount set forth in Section 13.4 below.

  
 Contributions considered under the first paragraph of this
Section 13.3 will include Employer contributions under this Plan and under all other defined contribution plans required to be included in an Aggregation Group (as defined in Section 13.7 below), but will not include Employer contributions
under any plan required to be included in such aggregation group if the plan enables a defined benefit plan required to be included in such group to meet the requirements of the Code prohibiting discrimination as to contributions in favor of
employees who are officers, shareholders or the highly compensated or prescribing the minimum participation standards. If the highest rate allocated to a Key Employee for a year in which the Plan is top-heavy is less then three percent (3%), amounts
contributed as a result of a salary reduction agreement must be included in determining contributions made on behalf of Key Employees. 
  
 Contributions considered under this Section will not include any contributions under the Social Security Act or any other federal or state law.

  
 13.4 Limitation on Compensation: The annual
compensation of a Member taken into account under this Article XIII and under Section 1.11 for purposes of computing benefits under this Plan shall not exceed $200,000. Such amount shall be adjusted automatically for each Plan Year to the
amount prescribed by the Secretary of the Treasury or his delegate pursuant to regulations for the calendar year in which such Plan Year commences. 
  
 13.5 Coordination with Other Plans: If another defined benefit plan maintained by a Considered Company provides contributions or benefits on behalf
of a Member in this Plan, such other plan shall be treated as a part of this Plan pursuant to applicable principles prescribed by U.S. Treasury Regulations or applicable IRS rulings (such as Revenue Ruling 81-202 or any successor ruling) to
determine whether this Plan satisfies the requirements of Sections 13.3 and 13.4 and to avoid inappropriate omissions or inappropriate duplication of minimum contributions. The determination shall be made by the Committee upon the advice of
counsel. In the event a Member is covered by a defined benefit plan which is top-heavy pursuant to Section 416 of the Code, a comparability analysis (as prescribed by Revenue Ruling 81-202 or any successor ruling) shall be performed in
order to establish that the plans are providing benefits at least equal to the defined benefit minimum. 
  
 13.6 Distributions to Certain Key Employees: Notwithstanding any other provision of this Plan to the contrary, the entire interest in this Plan of
each Member who is a five-percent owner (as described in Section 416(i)(1)(A) of the Code determined with respect to the Plan Year ending in the calendar year in which such individual attains age 70- 1/2) shall be distributed to such Member not later than the first day of April following the calendar year in which such individual attains age 70- 1/2. 
  
 13.7 Determination of Top-Heavy Status: The Plan will be a Top-Heavy Plan for any Plan Year if, as of the Determination Date, the aggregate of the
accounts under the Plan (determined as of the Valuation Date) for Members (including former Members) who are Key 
  

 46 

 
Employees exceeds sixty percent (60%) of the aggregate of the accounts of all Members, excluding former Key Employees, or if this Plan is required to be
in an Aggregation Group, any such Plan Year in which such Group is a Top-Heavy Group. In determining Top-Heavy status, if an individual has not performed one hour of service for any Considered Company at any time during the five-year period ending
on the Determination Date, any accrued benefit for such individual and the aggregate accounts of such individual shall not be taken into account. 
  
 For purposes of this Section, the capitalized words have the following meanings: 
  
 (a) “Aggregation Group” means the group of plans, if any, that includes both the group of plans
required to be aggregated and the group of plans permitted to be aggregated. The group of plans required to be aggregated (the “required aggregation group”) includes: 
  
 (i) Each plan of a Considered Company in which a Key Employee is a participant, including collectively
bargained plans, and 
  
 (ii) Each other plan,
including collectively bargained plans, of a Considered Company which enables a plan in which a Key Employee is a participant to meet the requirements of the Code, prohibiting discrimination as to contributions or benefits in favor of employees who
are officers, shareholders, or the highly compensated or prescribing minimum participation standards. 
  
 The group of plans that are permitted to be aggregated (the “permissive aggregation group”) includes the required aggregation group plus one or
more plans of a Considered Company that is not part of the required aggregation group and that the Considered Company certifies as a plan within the permissive aggregation group. Such plan or plans may be added to the permissive aggregation group
only if, after the addition, the aggregation group as a whole continues not to discriminate as to contributions or benefits in favor of officers, shareholders, or the highly compensated and to meet the minimum participation standards under the
Internal Revenue Code of 1986, as amended. 
  
 (b) “Determination Date” means for any Plan Year the last day of the immediately preceding Plan Year. However, for the first Plan Year of this Plan, Determination Date means the last day of that Plan Year. 
  
 (c) “Key Employee” means any Employee or former
Employee under this Plan who, at any time during the Plan Year in question or during any of the four preceding Plan Years, is or was one of the following: 
  
 (i) An officer of a Considered Company having an annual compensation greater than fifty percent (50%) of the amount in effect under
Section 415(b)(1)(A) of the Code for any such Plan Year. Whether an individual is an officer shall be determined by the Considered Company on the basis of all the facts and circumstances, such as an 

  

 47 

 
individual’s authority, duties, and term of office, not on the mere fact that the individual has the title of an officer. For any such Plan Year,
officers considered to be Key Employees will be no more than the fewer of: 
  
 (A) Fifty (50) Employees; or 
  
 (B) Ten percent (10%) of the Employees or, if greater than ten percent (10%), three (3) Employees. 
  
 For this purpose, the highest paid officers shall be selected. 
  

(ii) One of the ten (10) Employees owning (or considered as owning, within the meaning of the constructive ownership rules of
Section 416(i)(1)(B) of the Code) the largest interests in the Considered Company. An Employee who has some ownership interest is considered to be one (1) of the top ten (10) owners unless at least ten (10) other employees own a
greater interest than that Employee. However, an Employee will not be considered a top ten (10) owner for a Plan Year if the Employee earns less than the maximum dollar limitation on annual additions to a participant’s account in a defined
contribution plan under the Code, as in effect for the calendar year in which the Determination Date falls. 
  
 (iii) Any person who owns (or is considered as owning, within the meaning of the constructive ownership rules of Section 416(i)(1)(B)
of the Code) more than five percent (5%) of the outstanding stock of a Considered Company or stock possessing more than five percent (5%) of the combined voting power of all stock of the Considered Company. 
  
 (iv) Any person who has an annual compensation from the
Considered Company of more than One Hundred Fifty Thousand Dollars ($150,000) and who owns (or is considered as owning within the meaning of the constructive ownership rules of Section 416(i)(1)(B) of the Code) more than one percent
(1%) of the outstanding stock of the Considered Company or stock possessing more than one percent (1%) of the total combined voting power of all stock of the Considered Company. For purposes of this subsection, compensation means all items
includable as compensation for purposes of applying the limitations on annual additions to a Member’s account in a defined contribution plan and the maximum benefit payable under a defined benefit plan under the Code. 
  
 For purposes of this subsection (c), a Beneficiary of a Key Employee shall
be treated as a Key Employee. For purposes of parts (iii) and (iv), each Considered Company is treated separately in determining ownership percentages; but all such Considered Companies shall be considered a single employer in determining the
amount of compensation. 
  

 48 

 (d) “Non-Key Employee” means any employee (and any Beneficiary of an employee)
who is not a Key Employee. 
  
 (e)
“Top-Heavy Group” means the Aggregation Group, if as of the applicable Determination Date, the sum of the present value of the cumulative accrued benefits for Key Employees under all defined benefit plans included in the Aggregation Group
plus the aggregate of the accounts of Key Employees under all defined contribution plans included in the Aggregation Group exceeds sixty percent (60%) of the sum of the present value of the cumulative accrued benefits for all employees,
excluding former Key Employees as provided in paragraph (i) below, under all such defined benefit plans plus the aggregate accounts for all employees, excluding former Key Employees as provided in paragraph (i) below, under all such
defined contribution plans. In determining Top-Heavy status, if an individual has not performed one hour of service for any Considered Company at any time during the five-year period ending on the Determination Date, any accrued benefit for such
individual and the aggregate accounts of such individual shall not be taken into account. If the Aggregation Group that is a Top-Heavy Group is a required aggregation group, each plan in the group will be a Top-Heavy Plan. If the Aggregation Group
that is a Top-Heavy Group is a permissive aggregation group, only those plans that are part of the required aggregation group will be treated as Top-Heavy Plans. If the Aggregation Group is not a Top-Heavy Group, no plan within such group will be a
Top-Heavy Plan. 
  
 In determining whether this Plan constitutes
a Top-Heavy Plan, the Committee (or its agent) will make the following adjustments: 
  
 (f) When more than one plan is aggregated, the Committee shall determine separately for each plan as of each plan’s Determination
Date the present value of the accrued benefits (for this purpose using the actuarial assumptions set forth in the applicable plan or account balance). The results shall then be aggregated by adding the results of each plan as of the Determination
Dates for such plans that fall within the same calendar year. 
  
 (g) In determining the present value of the cumulative accrued benefit (for this purpose using the actuarial assumptions set forth in the applicable pension plan) or the amount of the account of any employee, such
present value or account will include the amount in dollar value of the aggregate distributions made to such employee under the applicable plan during the five-year period ending on the Determination Date unless reflected in the value of the accrued
benefit or account balance as of the most recent Valuation Date. The amounts will include distributions to employees representing the entire amount credited to their accounts under the applicable plan. 
  

 49 

 (h) Further, in making such determination, such present value or such account shall
include any rollover contribution (or similar transfer), as follows: 
  
 (i) If the rollover contribution (or similar transfer) is initiated by the employee and made to or from a plan maintained by another Considered Company, the plan providing the distribution shall include such
distribution in the present value of such account; the plan accepting the distribution shall not include such distribution in the present value of such account unless the plan accepted it before December 31, 1983. 
  
 (ii) If the rollover contribution (or similar transfer) is
not initiated by the employee or made from a plan maintained by another Considered Company, the plan accepting the distribution shall include such distribution in the present value of such account, whether the plan accepted the distribution before
or after December 31, 1983; the plan making the distribution shall not include the distribution in the present value of such account. 
  
 (i) In any case where an individual is a Non-Key Employee with respect to an applicable plan but was a Key Employee with respect to such
plan for any prior Plan Year, any accrued benefit and any account of such employee shall be altogether disregarded. For this purpose, to the extent that a Key Employee is deemed to be a Key Employee if he or she met the definition of Key Employee
within any of the four preceding Plan Years, this provision shall apply following the end of such period of time. 
  
 (j) “Valuation Date” means for purposes for determining the present value of an accrued benefit as of the Determination Date the
date determined as of the most recent valuation date which is within a twelve-month period ending on the Determination Date. For the first plan year of a plan, the accrued benefit for a current employee shall be determined either (i) as if the
individual terminated service as of the Determination Date or (ii) as if the individual terminated service as of the valuation date, but taking into account the estimated accrued benefit as of the Determination Date. The Valuation Date shall be
determined in accordance with the principles set forth in Q.&A. T-25 of Treasury Regulations Section 1.416-1. 
  
 (k) For purposes of this Article XIII, “Compensation” shall have the meaning given to it in Section 12(III)(5).

  

 50 

 ARTICLE XIV 
  
 TESTING OF CONTRIBUTIONS 
  
 14.1 Definitions: For purposes of this Article XIV, the capitalized words have the following meanings: 
  
 A. “After-Tax Contributions” shall mean those contributions
defined in Section 1.4. 
  
 B. “Compensation” shall
mean the Employee’s total Compensation for services rendered to an Employer during the Plan Year and, unless the Committee elects otherwise, the Employee’s Pre-Tax Contributions for the Plan Year and any amounts not currently included in
the Employee’s gross income by reason of the application of Section 125 or 132(f)(4) of the Code. 
  
 C. “Employer Contributions” shall mean the amounts contributed to the Trust Fund by the Employer pursuant to Section 4.2. 
  
 D. “Highly Compensated Employee” shall mean any Employee and any
employee of an Affiliate who is a highly compensated employee under Section 414(q) of the Code, including any Employee and any employee of an Affiliate who: 
  
 (i) was a 5% owner during the current Plan year or prior Plan Year; or 
  
 (ii) received Compensation during the Plan Year (as defined
in Section 12(III)(5) in excess of $85,000 or such other dollar amount as may be prescribed by the Secretary of the Treasury or his delegate and, if elected by the Employer, was in the ‘top-paid group’ (the top 20% of payroll) for the
Plan Year, excluding Employees described in Code Section 414(p)(8). 
  
 In determining an Employee’s status as a Highly Compensated Employee within the meaning of Section 414(q), the entities set forth in Treasury Regulation Section 1.414(q)-1T Q&A-6(a)(1) through
(4) must be taken into account as a single employer. 
  
 A
former Employee shall be treated as a Highly Compensated Employee if (1) such former Employee was a Highly Compensated Employee when such Employee separated from Service, or (2) such former Employee was a Highly Compensated Employee in
Service at any time after attaining age 55. 
  
 E. “Pre-Tax
Contributions” shall mean the amounts contributed to the Trust Fund out of a Member’s Compensation pursuant to Section 4.1(A). 
  

 51 

 14.2 Actual Deferral Percentage: The Actual Deferral Percentage for a specified group of Employees
for a Plan Year shall be the average of the ratios (calculated separately for each Employee in such group) of: 
  
 (a) The amount of Pre-Tax Contributions actually paid to the Plan on behalf of each such Employee for such Plan Year which relate to
Compensation that either would have been received by the Employee in such Plan Year (but for the deferral election) or are attributable to services performed by the Employee in the Plan Year and would have been received by the Employee within two
and one-half (2- 1/2) months after the close of the Plan Year (but for the deferral election), over

  
 (b) The Employee’s Compensation
for such Plan Year. 
  
 The individual ratios and Actual Deferral Percentages
shall be calculated to the nearest one-hundredth (1/100) of one percent (1%) of an Employee’s Compensation. 
  
 14.3 Actual Deferral Percentage Limits: The Actual Deferral Percentage for the eligible Highly Compensated Employees for any Plan Year shall not
exceed the greater of (a) or (b), as follows: 
  
 (a) The Actual Deferral Percentage of Compensation for the eligible non-Highly Compensated Employees times 1.25, or 
  
 (b) The lesser of (i) the Actual Deferral Percentage of Compensation for the eligible non-Highly Compensated Employees times 2.0 or
(ii) the Actual Deferral Percentage of Compensation for the eligible non-Highly Compensated Employees plus two (2) percentage points or such lesser amount as the Secretary of the Treasury shall prescribe to prevent the multiple use of this
alternative limitation with respect to any Highly Compensated Employee. 
  
 The Actual Deferral Percentage for any Highly Compensated Employee who is eligible to have deferred contributions allocated to his account under one or more plans described in Section 401(k) of the Code that are maintained by an
Employer or an Affiliate in addition to this Plan shall be determined as if all such contributions were made to this Plan. For purposes of determining whether the Actual Deferral Percentage limits of Section 14.3 are satisfied, all Pre-Tax
Contributions that are made under two or more plans that are aggregated for purposes of Code Section 401(a)(4) or 410(b) (other than Code Section 410(b)(2)(A)(ii)) are to be treated as made under a single plan and if two or more plans are
permissively aggregated for purposes of Code Section 401(k) the aggregated plans must also satisfy Code Sections 401(a)(4) and 410(b) as though they were a single plan. 
  
 14.4 Reduction of Pre-Tax Contribution Rates by Leveling Method: If on the basis of the Pre-Tax Contribution rates
elected by Members for any Plan Year, the Committee determines, in its sole discretion, that neither of the tests contained in (a) or (b) of Section 14.3 will be satisfied, the Committee may reduce the Pre-Tax Contribution rate of any
Member who is among the eligible Highly Compensated Employees to the extent necessary to reduce the overall 
  

 52 

 
Actual Deferral Percentage for eligible Highly Compensated Employees to a level which will satisfy either (a) or (b) of Section 14.3. The
reductions in Pre-Tax Contribution rates shall be made in a manner so that the Actual Deferral Percentage of the affected Members who elected the highest Actual Deferral Percentage shall be first lowered to the level of the affected Members who
elected the next to the highest Actual Deferral Percentage. If further overall reductions are required to achieve compliance with (a) or (b) of Section 14.3, both of the above-described groups of Members will be lowered to the level
of Members with the next highest Actual Deferral Percentage, and so on, until sufficient total reductions in Pre-Tax Contribution rates have occurred to achieve compliance with (a) or (b) of Section 14.3. 
  
 14.5 Increase in Pre-Tax Contribution Rates: If a Member’s
Pre-Tax Contribution rate is reduced below the level necessary to satisfy either (a) or (b) of Section 14.3 for the Plan Year, such Member may be eligible to increase his Pre-Tax Contribution rate for the remainder of the Plan Year to
a level not in excess of that level which will satisfy the greater of (a) or (b) of Section 14.3. Such an increase in the Pre-Tax Contribution rate shall be made by Members on a uniform and non-discriminatory basis, pursuant to such
rules and procedures as the Committee may prescribe. 
  
 14.6
Excess Pre-Tax Contributions: As soon as possible following the end of the Plan Year, the Committee shall determine whether either of the tests contained in Section 14.3 were satisfied as of the end of the Plan Year, and any excess
Pre-Tax Contributions, plus any income and minus any loss attributable thereto, of those Participants who are among the Highly Compensated Employees shall be distributed to such Participants in the manner provided below based on the amount of
Pre-Tax Contributions. In addition, the Employer Contribution made with respect to such excess Pre-Tax Contributions shall be forfeited and applied to reduce future Employer Contributions otherwise required under Section 4.2. Such income shall
include the allocable gain or loss for the Plan Year only. 
  
 The
amount of any excess Pre-Tax Contributions to be distributed to a Participant shall be reduced by Excess Deferrals previously distributed to him pursuant to Section 4.1 for the taxable year ending in the same Plan Year. All excess Pre-Tax
Contributions shall be returned to the Participants no later than the last day of the following Plan Year. The excess Pre-Tax Contributions, if any, of each Participant who is among the Highly Compensated Employees shall be determined by computing
the maximum Actual Deferral Percentage which each such Participant may defer under (a) or (b) of Section 14.3 and then reducing the Actual Deferral Percentage of some or all of such Participants through the distribution of such excess
Pre-Tax Contributions, on the basis of the amount of Pre-Tax Contributions of such Participants, as necessary to reduce the overall Actual Deferral Percentage for eligible Participants who are among the Highly Compensated Employees to a level which
satisfies either (a) or (b) of Section 14.3, according to the following procedures: 
  
 (a) the Pre-Tax Contributions of the Highly Compensated Employee or Employees with the highest dollar amount of Pre-Tax Contributions
shall be reduced to equal the dollar amount of the Pre-Tax Contributions of the Highly Compensated Employee or Employees with the next highest dollar amount of Pre-Tax Contributions; 
  

 53 

 (b) the reduction amount determined in clause (a) shall be distributed to the Highly
Compensated Employee or Employees who had the highest dollar amount of Pre-Tax Contributions prior to such reduction; and 
  
 (c) the procedures in clause (a) and (b) shall be repeated until the total excess Pre-Tax Contributions are distributed and
compliance is achieved with (a) or (b) of Section 14.3. 
  
 If these distributions are made, the Actual Deferral Percentage is treated as meeting the nondiscrimination test of Section 401(k)(3) of the Code regardless of whether the Actual Deferral Percentage, if recalculated after
distributions, would satisfy Section 401(k)(3) of the Code. The above procedures are used for purposes of recharacterizing excess Pre-Tax Contributions under Section 401(k)(8)(A)(ii) of the Code. For purposes of Section 401(m)(9) of
the Code, if a corrective distribution of excess Pre-Tax Contributions has been made, or a recharacterization has occurred, the Actual Deferral Percentage for Highly Compensated Employees is deemed to be the largest amount permitted under
Section 401(k)(3) of the Code. 
  
 The income or loss
attributable to the Participant’s excess Pre-Tax Contributions for the Plan Year shall be determined by multiplying the income or loss attributable to the Participant’s Pre-Tax Contribution Account balance for the Plan Year by a fraction,
the numerator of which is the excess Pre-Tax Contribution and the denominator of which is the Participant’s total Pre-Tax Contribution Account balance. Excess Pre-Tax Contributions shall be treated as Annual Additions under
Section 12(III)(8) of the Plan. 
  
 14.7 Contribution
Percentage: The Contribution Percentage for a specified group of Employees for a Plan Year shall be the average of the ratios (calculated separately for each Employee in such group) of: 
  
 (a) The total of the After-Tax Contributions and Employer
Contributions (the “Aggregate Contributions”) paid under the Plan on behalf of each Employee for such Plan Year which are made on account of the Employee’s Pre-Tax Contributions for the Plan Year, are allocated to the Employee’s
Employer Contribution Account and After-Tax Contribution Account during such Plan Year and are paid to the Trust no later than the end of the next following Plan Year, to 
  
 (b) The Employee’s Compensation for such Plan Year. 
  
 To the extent permitted by the Code and applicable regulations, the Employer may elect to
take into account, in computing the Contribution Percentage, pre-tax contributions made under this Plan or any other plan of the Employer. A Member’s Contribution Percentage shall be determined after determining the Member’s Excess
Deferrals, if any, pursuant to Section 4.1, and after determining the Member’s excess Pre-Tax Contributions pursuant to Section 14.6. 
  
 14.8 Contribution Percentage Limits: The Contribution Percentage for the eligible Employees for any Plan Year who are Highly Compensated Employees
shall not exceed the greater of (a) or (b), as follows: 
  
 (a) The Contribution Percentage for the eligible Employees who are not Highly Compensated Employees times 1.25, or 
  

 54 

 (b) The lesser of (i) the Contribution Percentage for the eligible Employees who are
not Highly Compensated Employees times 2.0 or (ii) the Contribution Percentage for the eligible Employees who are not Highly Compensated Employees plus two (2) percentage points or such lesser amount as the Secretary of the Treasury shall
prescribe to prevent the multiple use of this alternative limitation with respect to any Highly Compensated Employee. 
  
 The Contribution Percentage for any Highly Compensated Employee for any Plan Year who is eligible to have matching employer contributions made on his
behalf or to make after-tax contributions under one or more plans described in Section 401(a) of the Code that are maintained by an Employer or an Affiliate in addition to this Plan shall be determined as if all such contributions were made to
this Plan. 
  
 In the event that this Plan must be combined with
one or more other plans in order to satisfy the requirements of Code Section 410(b), then the Contribution Percentage shall be determined as if all such plans were a single plan. 
  
 14.9 Treatment of Excess Aggregate Contributions: If neither of the tests described above in Section 14.8 are
satisfied with respect to either Aggregate Contributions, the excess Aggregate Contributions, plus any income and minus any loss attributable thereto, shall be forfeited or, if not forfeitable, shall be distributed no later than the last day of the
Plan Year following the Plan Year in which such excess Aggregate Contributions were made. Such income shall include the allocable gain or loss for the Plan Year only. The income or loss attributable to the Participant’s excess Aggregate
Contributions for the Plan Year shall be determined by multiplying the income or loss attributable to the Participant’s Account for the Plan Year by a fraction, the numerator of which is the excess Aggregate Contribution, and the denominator of
which is the Participant’s total Account balance. Excess Aggregate Contributions shall be treated as Annual Additions under Section 12(III)(8) of the Plan. 
  
 The excess Aggregate Contributions, if any, of each Participant who is among the Highly Compensated Employees shall be
determined by computing the maximum Contribution Percentage under (a) or (b) of Section 14.8 and then reducing the Contribution Percentage of some or all of such Participants whose Contribution Percentage exceeds the maximum through
the distribution or forfeiture of the excess Aggregate Contributions, on the basis of the amount of such excess contributions attributable to such Participants, as necessary to reduce the overall Contribution Percentage for eligible Participants who
are among the Highly Compensated Employees to a level which satisfies either (a) or (b) of Section 14.8, according to the following procedures: 
  

(a) the Aggregate Contributions (as applicable) of the Highly Compensated Employee or Employees with the highest dollar amount of such
contributions shall be reduced to equal the dollar amount of the Aggregate Contributions of the Highly Compensated Employee or Employees with the next highest dollar amount of such contributions; 
  

 55 

 (b) the reduction amount determined in clause (a) shall be forfeited by or, if not
forfeitable, distributed to the Highly Compensated Employee or Employees who had the highest dollar amount of Aggregate Contributions prior to such reduction; and 
  
 (c) the procedures in clause (a) and (b) shall be repeated until the total excess Aggregate
Contributions are forfeited and/or distributed and compliance is achieved with (a) or (b) of Section 14.8. 
  
 If these forfeitures and/or distributions are made, the Contribution Percentage is treated as meeting the nondiscrimination test of Section 401(m)(2)
of the Code regardless of whether the Contribution Percentage, if recalculated after such forfeitures and/or distributions would satisfy Section 401(m)(2) of the Code. For purposes of Section 401(m)(9) of the Code, if a corrective
distribution of excess Aggregate Contributions has been made, the Contribution Percentage for Highly Compensated Employees is deemed to be the largest amount under Section 401(m)(2) of the Code. 
  
 For each Participant who is a Highly Compensated Employee, the amount of
excess Aggregate Contributions is equal to the total Employer Contributions and After-Tax Contributions on behalf of the Participant (determined prior to the application of this paragraph) minus the amount determined by multiplying the
Participant’s actual contribution ratio (determined after application of this paragraph) by his Compensation used in determining such ratio. The individual ratios and Contribution Percentages shall be calculated to the nearest 1/100 of 1% of
the Employee’s Compensation, as such term is used in paragraph (b) of Section 14.8. 
  
 14.10 Application of Participation and Discrimination Standards: The Plan will use the actual deferral percentage and the actual contribution
percentage for Members who are Highly Compensated Employees and non-highly compensated employees for the current Plan Year.

 58First Amendment to Savings Investment Plan

 Exhibit 10.20(a) 
  
 CABOT OIL & GAS CORPORATION 
 SAVINGS INVESTMENT PLAN 
  
 (As Amended and Restated Effective January 1, 2001) 
  
 First Amendment 
  
 Cabot Oil & Gas
Corporation, a Delaware corporation (the “Company”), having established the Cabot Oil & Gas Corporation Savings Investment Plan, as amended and restated January 1, 2001 (the “Plan”), and having reserved the right
under Section 10.4 thereof to amend the Plan, does hereby amend the Plan, to make certain law changes, including those which reflect certain provisions of the Economic Growth and Tax Relief Reconciliation Act of 2001 (“EGTRRA”). This
Amendment is intended as good faith compliance with the requirements of EGTRRA and is to be construed in accordance with EGTRRA and guidance issued thereunder. This Amendment shall supersede the provisions of the Plan to the extent those provisions
are inconsistent with the provisions of this Amendment. Except as otherwise provided, this Amendment shall be effective as of January 1, 2002. 
  
 1. The definition of “Compensation” in Section 1.11 of the Plan is hereby amended by adding the following sentence to the end thereof:

  
 “Effective as of January 1, 2002, Compensation
taken into account under the Plan for any Member during a Plan Year beginning on or after January 1, 2002 shall not exceed $200,000 (or such other amount provided under Section 401(a)(17) of the Code), as adjusted for cost-of-living
increases in accordance with Section 401(a)(17)(B) of the Code.” 
  
 2. The definition of “Rollover Amount” in Section 1.37 of the Plan is hereby amended by adding the following paragraph to the end thereof: 
  
 “Effective January 1, 2002, “Rollover Amount” may also include a transfer of assets made on or after
January 1, 2002, from the following types of plans: (i) a qualified plan described in 403(a) of the Code, including employee after-tax contributions; (ii) a qualified plan described in Section 403(b) of the Code, including
employee after-tax contributions; and (iii) an eligible plan under Section 457(b) of the Code which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state or political subdivision of a
state. The Plan will also accept a transfer of assets made on or after January 1, 2002, from the portion of a distribution from an individual retirement account or annuity described in Section 408(a) or 408(b) of the Code that is eligible
to be rolled over and would otherwise be includible in gross income. Notwithstanding the forgoing, no transfer of assets will be accepted if, upon acceptance of such transfer, the Plan would thereafter be required to provide for distributions in the
form of life annuities.”

 3. Section 2.15 of the Plan is hereby amended in its entirety to read as follows: 
  
 “2.15 Presenting Claims for Benefits: A ‘Claims
Administrator’ shall be appointed by the Committee or, absent such appointment, shall be the Company’s director of benefits, with such Claims Administrator authorized by the Committee to conduct the initial review and render a decision as
provided in this Section for all claims for benefits under the Plan. The Committee shall establish administrative processes and safeguards to ensure that benefit determinations made pursuant to this Section 2.15 are made in accordance with the
Plan and have been made and applied consistently to similarly situated claimants. Any Participant, Beneficiary of any deceased Participant, or the authorized representative of such claimant (collectively, the “Applicant”) may submit
written application to the Claim Administrator for the payment of any benefit asserted to be due him under the Plan. Such application shall set forth the nature of the claim and such other information as the Claim Administrator may reasonably
request. Promptly upon the receipt of any application required by this Section, the Claim Administrator shall determine whether or not the Participant or Beneficiary involved is entitled to a benefit hereunder and, if so, the amount thereof and
shall notify the Applicant of its findings. 
  
 (a) Non-Disability Claims. Except as provided in Section 2.15(b) below, if a claim is wholly or partially denied, the Claim Administrator shall so notify the Applicant within ninety (90) days after receipt of the
application by the Claims Administrator, unless special circumstances require an extension of time for processing the application. If such an extension of time for processing is required, written notice of the extension shall be furnished to the
Applicant prior to the end of the initial ninety (90) day period. In no event shall such extension exceed a period of ninety (90) days from the end of such initial period. The extension notice shall indicate the special circumstances
requiring an extension of time and the date by which the Claim Administrator expects to render its final decision. Notice of the Claim Administrator’s decision to deny a claim in whole or in part shall be set forth in a manner calculated to be
understood by the Applicant and shall contain the following: 
  
 (i) the specific reason or reasons for the denial, 
  
 (ii) specific reference to the pertinent Plan provisions on which the denial is based, 
  
 (iii) a description of any additional material or
information necessary for the Applicant to perfect the claim and an explanation of why such material or information is necessary, 
  
 (iv) an explanation of the claims review procedure, including applicable time limits, as set forth in Section 2.16 hereof, and

  

 2 

 (v) a statement of the claimant’s right to bring a civil suit under
Section 502(a) of ERISA following a denial on subsequent review. 
  
 (b) Disability Claims. If a claim for benefits based upon a Participant’s disability is wholly or partially denied, the Claim Administrator shall so notify the Applicant within forty-five (45) days
after receipt of the application by the Claims Administrator, unless special circumstances require an extension of time for processing the application. If such an extension of time for processing is required, the time for processing may be extended
for up to 30 days, if the Claim Administrator determines that the extension is necessary due to matters beyond the control of the Claim Administrator or the Plan and notifies the Applicant, before the expiration of the initial 45-day period, of the
circumstances requiring the extension of time and the date by which the claim decision is expected to be made. If, before the end of this 30-day extension period, the Claim Administrator determines that, due to matters beyond the control of the
Claim Administrator or the Plan, a decision cannot be rendered within that initial 30-day extension period, an additional 30-day extension may apply if the Applicant is given a notice satisfying the requirements set forth above for the first 30-day
extension. Any notice of extension must specifically explain the standards on which entitlement to a benefit is based, the unresolved issues that prevent a decision on the claim, and the additional information needed to resolve those issues. The
Applicant will be given at least 45 days in which to provide the specified information. In the event that the extension is a result of an Applicant’s failure to submit information necessary to decide a claim, the period in which the
determination must be made will be tolled from the date on which the notification of the extension is sent to the Applicant until the date the Applicant responds to the request for additional information. 
  
 Notice of the Claims Administrator’s decision to deny a
claim in whole or in part shall be set forth in a manner calculated to be understood by the Applicant and must contain the information described in clauses (i) through (v) of Section 2.15(a). Additionally, the notice of denial must
include: 
  
 (i) If any internal rule or
guideline was relied on in denying the claim, either the specific rule or guideline, or a statement that such a rule or guideline was relied on in denying the claim and that a copy of that rule or guideline will be provided to the Applicant free of
charge on request; and 
  
 (ii) If the claim
denial is based on an exclusion or limit related to medical necessity or experimental treatment, either an explanation of the scientific or clinical judgment for the determination as applied to the involved claimant’s circumstances, or a
statement that such an explanation will be provided to the Applicant free of charge upon request.”

 4. Section 2.16 of the Plan is hereby amended in its entirety to read as follows: 
  
 “2.16 Claims Review Procedure: Upon the Claims
Administrator’s denial, in whole or in part of a benefit applied for under Section 2.15, an Applicant shall have the right by written to appeal such denial as set forth in this Section 2.16. Benefits under the Plan will only be paid
if the Committee decides in its discretion that the claimant involved is entitled to them. The Committee shall establish administrative processes and safeguards to ensure that benefit determinations made pursuant to this Section 2.16 are made
in accordance with the Plan and have been made and applied consistently to similarly situated claimants. Except as may be otherwise required by law, the decision of the Committee on review of the claim denial shall be binding on all parties when the
Applicant has exhausted the claims procedure under this Section 2.16. 
  
 (a) Non-Disability Claims – General Rules. If an application filed by the Applicant under Section 2.15(a) above shall result in a denial by the Claim Administrator of the benefit applied for, either
in whole or in part, such Applicant shall have the right, to be exercised by written request filed with the Committee within sixty (60) days after receipt of notice of the denial of the application for a review of the application and of the
entitlement to the benefit for which the Applicant applied. Such request for review may contain such additional information and comments as the Applicant may wish to present. 
  
 The Committee shall reconsider the application in light of such additional information and comments as the
Applicant may have presented, and if the Applicant shall have so requested, shall afford the Applicant or his designated representative a hearing before the Committee. Upon request, the Committee shall provide, free of charge, the Applicant or his
designated representative with copies of all “relevant documents” (within the meaning of Department of Labor regulation Section 2560.503-1(m)(8)) (“Relevant Documents”) in its possession, including copies of the Plan
document and information provided by the Company relating to the Applicant’s entitlement to such benefit. 
  
 The Committee shall render a decision and notify the Applicant of the Committee’s determination on review no later than 60 days
after receipt of the Applicant’s request for review, unless the Committee determines that special circumstances (such as the need to hold a hearing) require an extension of time for processing the claim. If the Committee determines an extension
of time for processing is required, written notice of the extension shall be furnished to the Applicant prior to the termination of the initial 60-day period. In no event, shall such extension exceed a period of 60 days from the end of the
initial period. The extension notice shall indicate the special circumstance requiring an extension of time and the date by which the Committee expects to render the determination on review. In the event that the extension is a result of an
Applicant’s failure to submit information necessary to decide a claim, the period in which the determination must be made will be tolled from the date on which the notification of the extension is sent to the Applicant until the date the
Applicant responds to the request for additional information. 
  

 4 

 Notice of the Committee’s final decision shall be furnished to the Applicant in
writing, in a manner calculated to be understood by him, and if the Applicant’s claim on review is denied in whole or in part, the notice shall set forth: 
  

(i) the specific reason or reasons for the denial; and 
  
 (ii) specific reference(s) to the pertinent plan provision(s) on which the denial is based; and 

 
 (iii) the Applicant’s right to receive upon request,
free of charge, reasonable access to, and copies of, all Relevant Documents, records and other information to his claim; and 
  
 (iv) the claimant’s right to bring a civil action under Section 502(a) of ERISA. 
  
 (b) Non-Disability Claims – Special Rules.
Notwithstanding any other provision of Section 2.16(a), in the event that the Committee holds regularly scheduled meetings at least quarterly, the provisions of this Section 2.16(b) will apply and control, to the extent that this
Section 2.16(b) is inconsistent with the provisions of Section 2.16(a). Specifically, in the event that the Committee holds regularly scheduled meetings at least quarterly, the Committee shall render a determination on review of a
non-disability claim no later than the date of the Committee meeting next following receipt of the request for review, except that (i) a decision may be rendered no later than the second following Committee meeting if the request is received
within 30 days of the first meeting and (ii) under special circumstances which require an extension of time for rendering a decision (including but not limited to the need to hold a hearing), the decision may be rendered not later than the date
of the third Committee meeting following the receipt of the request for review. If such an extension of time for review is required because of special circumstances, written notice of the extension shall be furnished to the Applicant prior to the
commencement of the extension. In the event that the extension is a result of an Applicant’s failure to submit information necessary to decide a claim, the period in which the determination must be made will be tolled from the date on which the
notification of the extension is sent to the Applicant until the date the Applicant responds to the request for additional information. 
  
 Additionally, no later than five (5) days after the Committee has reached a final determination on review under this
Section 2.16(b), notice of the Committee’s final decision shall be furnished to the Applicant in writing, in the manner descried in Section 2.16(a). 
  

 5 

 (c) Disability Claims. If an application filed by an Applicant under
Section 2.15(b) above shall result in a denial by the Claims Administrator of the disability based benefit applied for, either in whole or in part, such Applicant shall have the right, to be exercised by written request filed with the Committee
within one-hundred and eighty (180) days after receipt of notice of the denial of the application, for a review of the application and of the entitlement to the benefit for which the Applicant applied. Such request for review may contain such
additional information and comments as the Applicant may wish to present. 
  
 The Committee shall reconsider the application in light of such additional information and comments as the Applicant may have presented, and if the Applicant shall have so requested, shall afford the Applicant or his
designated representative a hearing before the Committee. Upon request, the Committee shall provide, free of charge, the Applicant or his designated representative with copies of all Relevant Documents in its possession, including copies of the Plan
document and information provided by the Company relating to the involved claimant’s entitlement to such benefit. Additionally, the following requirements shall be imposed upon the Committee in reconsidering an Applicant’s request:

  
 (i) The Committee’s review will not give
deference to the original claim denial, and the review will not be made by the person who made the original claim denial, or a subordinate of that person; 
  
 (ii) In deciding an appeal of any claim denial that is based in any way on a medical judgment, the Committee will consult with a health
care professional who has appropriate training and experience in the field of medicine involved in the medical judgment; 
  
 (iii) The health care professional consulted by the Committee will not be an individual who was consulted in connection with the original
claim denial or a subordinate of any such individual; and 
  
 (iv) The Applicant will be provided the identification of medical or vocational experts whose advice was obtained on behalf of the Plan in connection with the claim denial, even if the advice was not relied upon in
making the claim denial. 
  
 The Committee shall
render a decision and notify the Applicant of the Committee’s determination on review within a reasonable period of time, but not later than 45 days after receipt of the Applicant’s request for review, unless the Committee determines
that special circumstances (such as the need to hold a hearing) require an extension of time for processing the claim. If the Committee determines an extension of time for processing is required, written notice of the extension shall be furnished to
the Applicant prior to the termination of the initial 

  

 6 

 
45-day period. In no event, shall such extension exceed a period of 45 days from the end of the initial period. The extension notice shall indicate the
special circumstance requiring an extension of time and the date by which the Committee expects to render the determination on review. In the event that the extension is a result of an Applicant’s failure to submit information necessary to
decide a claim, the period in which the determination must be made will be tolled from the date on which the notification of the extension is sent to the Applicant until the date the Applicant responds to the request for additional information.

  
 Notice of the Committee’s final decision
shall be furnished to the Applicant in writing, in a manner calculated to be understood by him, and if the Applicant’s claim on review is denied in whole or in part, the notice shall contain the information described in clauses (i) through
(iv) of Section 2.16(a). Additionally, the notice of denial shall include: 
  
 (i) If any internal rule or guideline was relied on in denying the claim on appeal, either the specific rule or guideline, or a statement
that such a rule or guideline was relied on in denying the claim and that a copy of that rule or guideline will be provided to the Applicant free of charge on request; and 
  
 (ii) If the claim denial on appeal is based on an exclusion or limit like medical necessity or experimental
treatment, either an explanation of the scientific or clinical judgment for the determination as applied to the involved claimant’s circumstances, or a statement that such an explanation will be provided to the Applicant free of charge upon
request.” 
  
 5. Section 4.1 of the Plan is hereby
amended by deleting the phrase “fifteen percent (15%)” in each place it appears in Section 4.1 and replacing each such occurrence with the phrase “twenty-five percent (25%)”. 
  
 6. Section 4.1(A) of the Plan is hereby amended by adding the following
sentence to the end thereof: 
  
 “For Plan Years beginning
on or after January 1, 2002, a Member’s Pre-Tax Contributions per Plan Year under this Plan and all other plans, contracts or arrangements of the Employer shall not exceed a maximum dollar limitation provided under Section 402(g) of
the Code, as adjusted by the Secretary of the Treasury or his delegate for cost-of-living increases pursuant to Section 402(g) of the Code, except to the extent permitted under Section 4.1(C) of the Plan with respect to Catch-Up
Contributions, as defined therein.” 
  
 7. Effective
July 1, 2002, Section 4.1 of the Plan is hereby amended by adding the following subsection 4.1(C) to the Plan, to read in its entirety as follows: 
  
 “C. Catch-Up Contributions: Effective July 1, 2002, each Member who may elect to make Pre-Tax Contributions under Section 4.1(A) of
this Plan and 

  

 7 

 
who has attained age 50 before the close of the Plan Year shall be eligible to elect to make ‘catch-up contributions’ in accordance with, and
subject to the limitations of, of Section 414(v) of the Code (‘Catch-Up Contributions’), in the form and manner prescribed by the Committee. Such Catch-Up Contributions shall not be taken into account for purposes of the provisions of
the Plan implementing the required limitations of Sections 402(g) and 415 of the Code. Additionally, such Catch-Up Contributions shall not participate in, or be considered in determining, the amount of Employer Contributions under Section 4.2
of the Plan. The Plan shall not be treated as failing to satisfy the provisions of the Plan implementing the requirements of Sections 401(k)(3), 401(k)(11), 401(k)(12), 410(b), or 416 of the Code, as applicable, by reason of the making of such
Catch-Up Contributions.” 
  
 8. Section 7.4 of the Plan
is hereby amended by adding the following sentence to the end thereof: 
  
 “Effective January 1, 2002, subject to the other provisions of this Section 7.4 and this Plan, a termination of Service for purposes of this Section 7.4 shall include a Member’s
“severance from employment” under Section 401(k)(2)(B)(i)(I) of the Code, occurring on or after January 1, 2002.” 
  
 9. The third paragraph of Section 8.1 of the Plan is hereby amended by adding the following sentence to the end thereof: 
  
 “As of April 1, 2003 or, if later, the
ninety-first day following delivery of notice to Members describing the elimination from this Plan of payment options as provided under the Profit Sharing Plan and the ESOP, such payment options shall be eliminated under this Plan for distributions
to any Member whose Distribution Date is on or after said date.” 
  
 10. The first sentence of the fourth paragraph of Section 8.1 of the Plan is hereby amended in its entirety to read as follows: 
  
 “If the amount to which a terminated Member is entitled is not more than $5,000, including the balance of such Member’s Rollover
Account, such amount shall be paid to the Member as soon as practicable after his Distribution Date; if such amount is in excess of $5,000, the distribution shall be made only if the Member so consents.” 
  
 11. Section 8.5(B)(a) of the Plan is hereby amended by adding the
following paragraph to the end thereof: 
  
 “Effective January 1, 2002, any amount that is distributed on account of hardship shall not be an eligible rollover distribution and the distributee may not elect to have any portion of such a distribution paid directly to an
eligible retirement plan. Additionally, effective January 1, 2002, a portion of a distribution shall not fail to be an eligible rollover distribution merely because the portion consists of after-tax employee contributions which are not
includible in 

  

 8 

 
gross income. However, such portion may be transferred only to an individual retirement account or annuity described in Section 408(a) or (b) of
the Code, or to a qualified defined contribution plan described in Section 401(a) or 403(a) of the Code that agrees to separately account for amounts so transferred, including separately accounting for the portion of such distribution which is
includible in gross income and the portion of such distribution which is not so includible.” 
  
 12. Section 8.5(B)(b) of the Plan is hereby amended in its entirety to read as follows: 
  
 “(b) Eligible Retirement Plan: An eligible retirement plan is
(i) an individual retirement account described in Section 408(a) of the Code, (ii) an individual retirement annuity described in Section 408(b) of the Code, (iii) an annuity plan described in Section 403(a) of the Code,
(iv) an annuity contract described in Section 403(b) of the Code, (v) an eligible plan under Section 457(b) of the Code which is maintained by a state, political subdivision of a state, or any agency or instrumentality of a state
or political subdivision of a state and which agrees to separately account for amounts transferred into such plan from this Plan, or (vi) a qualified trust described in Section 401(a) of the Code, that accepts the distributee’s
eligible rollover distribution. However, prior to January 1, 2002, in the case of an eligible rollover distribution to a surviving spouse, an eligible retirement plan is an individual retirement account or individual retirement annuity.”

  
 13. The definition of “Maximum Permissible Amount”
in Section 12(III)(4) of the Plan is hereby amended in its entirety to read as follows: 
  
 “4. Maximum Permissible Amount: Except to the extent permitted under Section 4.1(C) of the Plan with respect to
Catch-Up Contributions and Section 414(v) of the Code, if applicable, for a Limitation Year, the Maximum Permissible Amount with respect to any Member shall be the lesser of: 
  
 A. $40,000, as adjusted by the Secretary of the Treasury or his delegate pursuant to Code
Section 415(d); or 
  
 B. 100% of the
Member’s compensation, within the meaning of Section 415(c)(3) of the Code, for the Limitation Year. The compensation limit referred to in this clause (B) shall not apply to any contribution for medical benefits after separation from
service (within the meaning of Section 401(h) or Section 419A(f)(2) of the Code) which is otherwise treated as an Annual Addition. 
  
 The foregoing notwithstanding, the Maximum Permissible Amount shall not include contributions related to qualified military service under
Section 3.12 of the Plan.” 
  

 9 

 14. The definition of “Compensation” in Section 12(III)(5) of the Plan is hereby amended
by adding the following sentence to the end thereof: 
  
 “The foregoing notwithstanding, for purposes of applying the limitations in this Article for Limitation Years beginning on or after January 1, 2002, Compensation shall be limited to $200,000 (or such other amount provided under
Section 401(a)(17) of the Code), as adjusted for cost-of-living increases in accordance with Section 401(a)(17)(B) of the Code.” 
  
 15. Section 13(III)(8) of the Plan is hereby amended in its entirety to read as follows: 
  
 “8. Annual Additions: With respect to each Limitation Year, the
total of the Employer Contributions, Pre-Tax Contributions, After-Tax Contributions. Forfeitures, and amounts described in Code Sections 415(l) and 419A(d)(2) which are allocated to a Member’s Account; excluding, however, any Catch-Up
Contributions permitted under Section 4.1(C) of the Plan.” 
  
 16. The last sentence in the first paragraph of Section 13.3 of the Plan is hereby amended to read as follows: 
  
 “For this purpose, the percentage with respect to a Key Employee will be determined by dividing the contributions (including Forfeitures) made for
such Key Employee by his total compensation (as defined in Section 415 of the Code) not in excess of $200,000 (or such other amount provided under Code Section 401(a)(17)) for the Plan Year.” 
  
 17. The first sentence in Section 13.4 of the Plan is hereby amended to
read as follows: 
  
 “The annual compensation of a Member
taken into account under this Article XIII and under Section 1.11 for purposes of computing benefits under this Plan will not exceed $200,000 (or such other amount provided under Section 401(a)(17) of the Code), as adjusted by the
Secretary of the Treasury or his delegate for cost-of-living increases in accordance with Section 401(a)(17)(B) of the Code.” 
  
 18. Article XIII of the Plan is hereby amended by adding the following new Section 13.8 to the end thereof: 
  
 “13.8. Modification of Top-Heavy Rules: 
  
 (a) Effective Date. This Section shall apply for purposes of
determining whether the Plan is a top-heavy plan under Section 416(g) of the Code for Plan Years beginning after December 31, 2001, and whether the Plan satisfies the minimum benefits requirements of Section 416(c) of the Code for
such years, and, as applicable, amends this Article XIII of the Plan. 
  

 10 

 (b) Determination of Top-Heavy Status. 
  
 1. ‘Key Employee’ means any Employee or former Employee
(including any deceased Employee) who at any time during the Plan Year that includes the Determination Date was an officer of a Considered Company having annual compensation greater than $130,000 (as adjusted under Section 416(i)(1) of the Code
for Plan Years beginning after December 31, 2002), a 5-percent owner of a Considered Company, or a 1-percent owner of a Considered Company having annual compensation of more than $150,000. For this purpose, annual compensation means
compensation within the meaning of Section 415(c)(3) of the Code. The determination of who is a Key Employee will be made in accordance with Section 416(i)(1) of the Code and the applicable regulations and other guidance of general
applicability issued thereunder. 
  
 2. This subparagraph
(2) shall apply for purposes of determining the present values of accrued benefits and the amounts of account balances of Employees as of the Determination Date. 
  
 (A) Distributions during year ending on the Determination Date. The present values of accrued benefits and the
amounts of account balances of an Employee as of the Determination Date shall be increased by the distributions made with respect to the Employee under the Plan and any plan aggregated with the Plan under Section 416(g)(2) of the Code during
the 1-year period ending on the Determination Date. The preceding sentence shall also apply to distributions under a terminated plan which, had it not been terminated, would have been aggregated with the Plan under Section 416(g)(2)(A)(i) of
the Code. In the case of a distribution made for a reason other than separation from service, death, or disability, this provision shall be applied by substituting ‘5-year period’ for ‘1-year period.’ 
  
 (B) Employees not performing services during the year ending on the
Determination Date. The accrued benefits and accounts of any individual who has not performed services for a Considered Company during the 1-year period ending on the Determination Date shall not be taken into account. 
  
 (c) Minimum Benefits. Employer matching contributions shall be taken
into account for purposes of satisfying the minimum contribution requirements of Section 416(c)(2) of the Code and the Plan. The preceding sentence shall apply with respect to matching contributions under the Plan or, if the Plan provides that
the minimum contribution requirement shall be met in another plan, such other plan. Employer 

  

 11 

 
matching contributions that are used to satisfy the minimum contribution requirements shall be treated as matching contributions for purposes of the actual
contribution percentage test and other requirements of Section 401(m) of the Code.” 
  
 19. Article XIV of the Plan is hereby amended by adding the following new Section 14.11 to the end thereof: 
  
 “14.11. Multiple Use Test. The multiple use test described in Treasury Regulation Section 1.401(m)- 2 shall not apply for Plan Years
beginning after December 31, 2001.” 
  
 IN WITNESS
WHEREOF, the Company has caused this Amendment to be executed by its duly authorized officer this      day of
                    , 2002, but effective as specified herein.
