CABOT OIL & GAS CORPORATION SAVINGS INVESTMENT PLAN 

(As Amended and Restated Effective January 1, 2009) 
 First Amendment 
 WHEREAS, effective January 1, 1991, Cabot
Oil & Gas Corporation (the “Company”) established the Cabot Oil & Gas Corporation Savings Investment Plan and has amended and restated the Plan on several occasions since that date, most recently as of January 1,
2009 (the “Plan”); and 
 WHEREAS, the Company desires to amend the Plan to provide for discretionary profit sharing
contributions, to authorize the Plan to accept a direct rollover to a Member’s account of any eligible distribution to such Member from the Cabot Oil & Gas Corporation Pension Plan, to remove the Cabot Corporation Common Stock Fund and
to make certain changes required by the Heroes Earnings Assistance and Relief Tax Act of 2008; 
 NOW, THEREFORE, having
reserved the right to amend the Plan pursuant to Section 10.4 thereof, the Company hereby amends the Plan, effective, unless otherwise provided below, as of October 1, 2010, as follows: 

1. Section 1.21 of the Plan is hereby amended, in its entirety, to read as follows: 

“1.21 Employer Contribution Account: The account maintained for a Member to record his share of the
Contributions of his Employer and adjustments relating thereto. This account shall include the following sub-accounts, to the extent applicable: (a) the Matching Contribution Sub-Account, which shall reflect Matching Contributions made on the
Member’s behalf; and (b) the Discretionary Profit Sharing Contribution Sub-Account, which shall reflect Discretionary Profit Sharing Contributions made on the Member’s behalf.” 

2. Section 1.43 of the Plan is hereby amended, in its entirety, as follows: 

“1.43 Rollover Account: The separate sub-account established and maintained on behalf of a Member or
Beneficiary to reflect his interest in the Trust Fund 

  
 1 

 
attributable to Rollover Contributions. The Committee, in its sole discretion, may choose to establish such sub-accounts within a Member’s or Beneficiary’s Rollover Account as the
Committee deems appropriate.” 
 3. Section 1.44 of the Plan is hereby amended, in its entirety, to read as follows:

 “1.44 Rollover Contribution: Any amount contributed to the Plan by an Employee or Member pursuant
to Section 4.9.” 
 4. Effective January 1, 2010, or such earlier date as is specified below, Section 3.12
of the Plan is hereby amended, in its entirety, to read as follows: 
 “3.12. Qualified Military
Service: 
 (a) Notwithstanding any provision of this Plan to the contrary, contributions, benefits and
service credit with respect to Qualified Military Service, as such term is defined in Section 414(u)(5) of the Code, will be provided in accordance with Section 414(u) of the Code. Specifically, as required by Section 414(u)(8) of the
Code, the Member will be treated as not having incurred a Break in Service because of his period of Qualified Military Service, the Member’s Qualified Military Service will be treated as Service under the Plan, and the Member will be permitted
to make up any contributions he would have otherwise been eligible to make during the period of Qualified Military Service. 
 (b) If a Member’s death occurs on or after January 1, 2007, while performing Qualified Military Service, then, provided such Member was entitled to reemployment rights with respect to the
Employer under Code Section 414(u) as of the date of his death, the Member’s Beneficiary or Beneficiaries shall be entitled to any benefits (other than benefit accruals relating to the period of Qualified Military Service) that would be
provided under the Plan if the Member had resumed and then terminated his Service on account of death, in compliance with Code Section 401(a)(37) and the Treasury regulations and guidance issued by the Internal Revenue Service thereunder.

 (c) If an individual is paid remuneration by an Employer after December 31, 2008 that constitutes a
“differential wage payment” within the meaning of Code 

  
 2 

 
Section 3401(h)(2), then (i) such individual shall be treated as an Employee of the Employer making the payment, (ii) the differential wage payment shall be treated as Compensation
solely for purposes of Section 12.1(c) of the Plan. 
 (d) No Member or Beneficiary shall be entitled to any
continued benefit accruals or employer contributions under Code Section 414(u)(9) (as enacted under section 104(b) of the Heroes Earnings Assistance and Relief Act of 2008) by reason of incurring a death or disability during a period of
Qualified Military Service.” 
 5. Section 4.4 of the Plan is hereby amended, in its entirety, to read as follows:

 “4.4 Employer Contributions: Employer Contributions may be made in the form of Matching
Contributions and/or Discretionary Profit Sharing Contributions, each as defined below. Employer Contributions 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. 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. 

(a) Matching 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 (‘Matching Contribution’). ‘Basic Savings Contributions’ means each Member’s
first six percent (6%) of Pre-Tax Contributions. After the close of each Plan Year, the applicable Employer shall make an additional Employer Contribution for each Member who is an active Member on the last day of such Plan Year in an amount
equal to the difference, if any, between (1) 100% of the first 6% of the Member’s Pre-Tax Contributions (but not Catch-up Contributions) for the Plan Year and (2) the sum of the Employer Matching Contributions made for such Members
for all payroll periods during the Plan Year. 

  
 3 

 (b) Discretionary Profit Sharing Contributions. For each Plan Year,
the Board of Directors, in its sole and absolute discretion, may direct an Employer to make an Employer Contribution on behalf of each Member who is actively employed by such Employer during such Plan Year in an amount designated by the Board of
Directors (‘Discretionary Profit Sharing Contribution’). Notwithstanding the foregoing, the Board of Directors is not required to authorize a Discretionary Profit Sharing Contribution for a Plan Year.” 

6. Section 4.7 of the Plan is hereby amended, in its entirety, to read as follows: 

“4.7 Delivery to Trustee. Each Employer shall transmit Contributions to the Trustee as soon as practicable,
but in any event no later than the date required by law; provided, however, that all Employer Contributions shall be transmitted to the Trustee no 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.” 
 7. Section 4.9 of the Plan is
hereby amended, in its entirety, to read as follows: 
 “4.9 Rollover Contributions: Notwithstanding
any other provision of the Plan, subject to the terms and conditions set forth in this Section, the Trustee shall be authorized to accept a rollover of an Eligible Rollover Distribution, as defined in Section 8.5, on behalf of or from a person
who is (or who will be entitled under Section 3.1 to become) a Member in the Plan, from an Eligible Retirement Plan, as defined in Section 8.5. Such a transferred distribution is referred to herein as a ‘Rollover Contribution.’

 The acceptance of Rollover Contributions under this Section shall be subject to the following conditions:

 (a) No Rollover Contribution shall be in an amount less than $500; 

(b) Rollover Contributions shall be in cash only; 

(c) No Rollover Contribution may be transferred to the Plan without the prior approval of the Committee. The Committee
shall develop such procedures and may require such information from an Employee desiring to make such 

  
 4 

 
a transfer as it deems necessary or desirable. The Committee may act in its sole discretion in determining whether to accept the transfer, and shall act in a uniform, non-discriminatory manner in
this regard; 
 (d) Upon approval by the Committee, a Rollover Contribution shall be paid to the Trustee to be
held in the Trust Fund; 
 (e) A separate Rollover Account shall be established and maintained for each Employee
who has made a Rollover Contribution. A Rollover Account shall be invested in the Investment Funds and/or the Company Stock Fund as elected by the Employee, in the form and manner prescribed by the Committee, when the Rollover Contributions are
received by the Trust Fund, and thereafter the Employee may change his investments in accordance with Section 9.4 of the Plan. The Employee’s interest in his Rollover Account shall be fully vested and non-forfeitable. If an Employee who is
otherwise eligible to participate in the Plan but who has not yet begun participation under Section 3.1 of the Plan makes a Rollover Contribution to the Plan, his Rollover Account shall represent his sole interest in the Plan until he becomes a
Member; 
 (f) The Committee shall be entitled to rely on the representation of the Employee that the Rollover
Contribution is an eligible rollover distribution. If, however, it is determined that a transfer received from or on behalf of an Employee failed to qualify as an eligible rollover distribution within the meaning of Code Section 402(c)(4), then
the balance in the Employee’s Rollover Account attributable to the ineligible transfer shall, along with any earnings thereon, as soon as is administratively practicable, be: 

(1) segregated from all other Plan assets; 

(2) treated as a non-qualified trust established by and for the benefit of the Member; and 

(3) distributed to the Employee. 

Such an ineligible transfer shall be deemed never to have been a part of the Plan or Trust; and 

  
 5 

 (g) The Plan shall accept a direct Rollover Contribution from the Cabot
Oil & Gas Corporation Pension Plan by any Member (or Employee eligible to become a Member) who, as of the date of such Rollover Contribution, has an Account balance in the Plan, and such amount shall be maintained in a Rollover Account
maintained on behalf of the Member.” 
 8. Section 5.2(c) of the Plan is hereby amended, in its entirety, to
read as follows: 
 “(c) Employer Contributions. No less frequently than once each Plan Year and more
frequently as may be specified by the Committee, the Employer Contributions for such Plan Year shall be allocated among its Members during such Plan Year or partial Plan Year, as follows: 

(1) Matching Contributions. Matching Contributions shall be allocated to the Member’s Matching Contribution
Sub-Account in the ratio that each Member’s unwithdrawn Basic Savings Contributions (as defined in Section 4.4) for the applicable 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. 
 (2) Discretionary Profit Sharing Contributions.
Discretionary Profit Sharing Contributions received in the Trust Fund for a Plan Year, if any, shall be allocated on each Allocation Date to the Discretionary Profit Sharing Contribution Sub-Account of each eligible Member in the ratio that the
Member’s Considered Compensation for the applicable Allocation Period bears to the aggregate Considered Compensation of all Members for such Allocation Period. For purposes of this Section 5.2(c)(2), (i) ‘Allocation Date’
means the date on which an allocation of Discretionary Profit Sharing Contributions; (ii) ‘Allocation Period’ shall mean the period commencing on the date next following the previous Allocation Date and ending on the current
Allocation Date; and (iii) ‘Considered Compensation’ shall mean a Member’s Compensation for the applicable Allocation Period; For the Plan Year ending December 31, 2010, a Member’s Considered Compensation shall not

  
 6 

 
include Compensation attributable to services performed prior to October 1, 2010 and no Allocation Date shall be deemed to have occurred prior to October 1, 2010.” 

9. Section 6.5 of the Plan is hereby amended, in its entirety, to read as follows: 

“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 other than the Discretionary Profit Sharing Sub-Account and the portion of the
Rollover Account attributable to rollovers from the Cabot Oil & Gas Corporation Pension Plan (the “Loan Eligible Account”). 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 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 Loan Eligible 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 

  
 7 

 
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 any portion of the Loan Eligible 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 Loan Eligible 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 

  
 8 

 
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 Loan
Eligible Account of such Borrower. 
 (g) A loan to a Borrower shall be considered an investment of the separate
Loan Eligible Account(s) of the Borrower from which the loan is made. All loan repayments shall be credited pro rata to such separate Loan Eligible 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.” 
 10. The fourth
paragraph of Section 8.1 of the Plan is hereby amended to read as follows: 
 “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 Oil & 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.” 
 11. Section 9.2 of the Plan is hereby amended, in its entirety, to read as follows: 
 “9.2 Investment Funds: The Trustee shall divide the Trust Fund into the Cabot Oil & Gas Corporation Stock Fund and such additional Investment Funds which shall be selected and
reviewed from time to time by the Committee. Effective September 30, 2010, the Cabot 

  
 9 

 
Corporation Common Stock Fund shall no longer be offered pursuant to the Plan. 
 Contributions shall be paid into the 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.” 

IN WITNESS WHEREOF, the Company, acting by and through its duly authorized officer, has caused this Amendment to be executed as of the
10th day of September 2010, to become effective as of the dates set forth above.

5. TERMINATION OF PARTICIPANT’S EMPLOYMENT. 
 5.1. Additional Allocation. Notwithstanding any other provision of the Plan to the contrary, a Participant shall be entitled to receive an Allocation for the Plan Year in which his employment with

reason” or reasonably equivalent term as defined in his Employment Agreement;

 (f) incurring
a total and permanent disability, which shall be deemed to occur if a Participant is eligible to receive benefits under the terms of the long-term disability program maintained by the Participating Company that employs the Participant. 

This Allocation for the relevant Plan Year in which the Participant’s termination occurs shall equal the Participant’s
Compensation for such Plan Year (including any severance amount, if applicable) multiplied by his Allocation Percentage, less his PSSP Supplemental Contribution. 
 5.2. Crediting of Additional Allocation. Upon the occurrence of any one (but only one) of the events of termination described in Section 5.1, the Account of the affected Participant shall be
credited with the additional Allocation immediately. For purposes of the calculation of the additional Allocation amount, in the event of any occurrences described in Section 5.1(a) through (c) above, all severance payments (regardless of
when paid and actually received by the Participant), shall be included in Compensation for the Plan Year in which the actual termination of employment occurs. 
 5.3. Non-Duplication of Benefits. Upon the occurrence of more than one event described in Section 5.1, the affected Participant shall be credited with only one additional Allocation, based on
the event that occurs first.

any reason not specified in Section 5.1 or for no reason, he shall be entitled to payment of the notional balance in his Account at the time of such termination as provided in Section 6 herein, without any Allocation to his Account for the
Plan Year in which his employment is terminated.

6.1 Time of Payment. Payment to a Participant (or his beneficiary) of the notional amount credited to his Account shall be made as
soon as practicable

following termination of his employment for any reason (“Date of Termination”) and, except as provided below, in all events within thirty (30) days following the Participant’s
Date of Termination; provided, however, notwithstanding the foregoing, a payment to a Participant may, in the discretion of the Compensation Committee, be made later than thirty (30) days following the Participant’s Date of Termination, at
anytime during the calendar year that includes the Participant’s Date of Termination (or, if later, by the
15th day of the third calendar month following the
Participant’s Date of Termination) and, in such event, shall be based on the number of Phantom Units credited to the Participant’s Account at the time of payment and shall be deemed for purposes of Section 409A of the Internal Revenue
Code to have been made on the Participant’s Date of Termination. For purposes of the Plan, a Participant shall be considered to have terminated employment when he incurs a “separation from service” within the meaning of
Section 409A of the Internal Revenue Code and the applicable administrative guidance issue thereunder. Notwithstanding anything in the Plan to the contrary, in no event shall a payment to a Participant be made prior to his “separation from
service”. 
 6.2. Form of Payment; Common Units. Except for any payment of an Account payable in January, 2011
(which shall be paid in cash, subject to applicable withholding) payment shall be in Common Units (subject to applicable withholding). The Partnership shall file and register this Plan on Form S-8 with the SEC prior to any payment of Common Units,
such that all Common Units issued to a Participant (or his beneficiary) pursuant to this Plan be freely tradable under the Securities Act, subject only to the volume limitations set forth in Rule 144(k) promulgated under the Securities Act as may be
applicable to former affiliates of the Partnership. The Partnership shall maintain a current prospectus, if required, under Form S-8 until such Participant either has sold or may sell all of his Common Units without restriction as to the volume of
trading under Rule 144(e). For any payment hereunder, the Company shall cause the Partnership to issue the number of Common Units equivalent to the notional number of Phantom Units held in the Participant’s Account. 

6.3. [Deleted] 

6.4. Death. Any benefits due under this Plan to a Participant upon his death shall be paid to the Participant’s beneficiary.
A Participant may designate a beneficiary (which may be other than a natural person) to receive all benefits which may be payable at the Participant’s death by completing the form furnished by the Plan Administrator. A Participant may change
the beneficiary designation at any time without notice to any beneficiary, but such change shall not be effective until it is received by the Plan Administrator. If a Participant fails to file a proper beneficiary designation form with the Plan
Administrator, or if the designated beneficiary predeceases the Participant, any benefits which may be payable upon the Participant’s death shall be paid in a single sum to the Participant’s surviving spouse, if any, or otherwise to the
Participant’s estate. Payment due under this 

  
 7 

 
Section 6.4 shall be made as soon as practicable following the Participant’s death and in no event later than (a) the end of the calendar year of the Participant’s death or
(b) 2 1/2 months following the date of the
Participant’s death, whichever is later. 
 7. AMENDMENT AND TERMINATION. 

7.1. Right to Amend/Terminate. The Compensation Committee reserves the right to amend the Plan and to terminate the Plan at any
time; provided, however, that no amendment or termination shall have the affect, directly or indirectly, of modifying or reducing a Participant’s benefits, or any rights to benefits, that have accrued as of the date of the amendment or
termination, without the written consent of the Participant. 
 8. ADMINISTRATION OF PLAN. 

8.1. Administration. The Plan Administrator may delegate responsibility for the day-to-day administration and operation of the Plan
to the Compensation Committee and to employees of the Company or any Participating Company. The Plan Administrator (or the entity or individual to which administrative authority has been delegated) shall have the authority to interpret and construe
any and all provisions of the Plan. Any determination made by the Plan Administrator (or the entity or individual to which administrative authority has been delegated) shall be final and conclusive. 

8.2. Indemnification. Neither any Participating Company, nor the Board of Directors, or any member of any committee thereof, of
any Participating Company, nor any employee of any Participating Company shall be liable for any act, omission, interpretation, construction or determination made in connection with the Plan in good faith; and the members of the Board of Directors,
and the employees, of any Participating Company shall be entitled to indemnification and reimbursement by the Company to the maximum extent permitted by law in respect of any claim, loss, damage or expense (including counsel’s fees) arising
from their acts, omission and conduct in their official capacity with respect to the Plan. 
 8.3. Exempt Plan. All
notional credits of Phantom Units to any Participant’s Account as provided under the terms of this Plan, and any issuance of Common Units to a Participant (or his beneficiary) under this Plan upon his termination of employment with a
Participating Company, are intended to be transactions which are exempt from the provisions of Section 16(b) of the Exchange Act, as provided under Rule 16b-3(d)(1) promulgated under the Exchange Act. 

9. GENERAL PROVISIONS. 

9.1. Unfunded Benefit. Benefits payable under the Plan to any person shall be paid directly by the Participating Company which
employs such Participant. If a Participant is employed by more than one Participating Company, benefits shall be 

  
 8 

 
paid by the Participating Company that receives the greatest share of the Participant’s services. Nothing contained in this Plan, and no action taken pursuant to the provisions of this Plan,
shall create or be construed to create a trust or separate fund of any kind, or a fiduciary relationship between any Participating Company and any Employee, any beneficiary or any other person. Any funds representing amounts credited to a
Participant’s Account hereunder shall at all times remain the property of the Participating Company which employs such Participant, and such funds shall continue to be a part of the general funds of such Participating Company. To the extent
that any person acquires a right to receive payments under this Plan from a Participating Company, such right shall be no greater than the right of an unsecured general creditor of such Participating Company. 

9.2. Non-Guarantee of Employment. Nothing contained in this Plan shall be construed as a contract of employment between a
Participating Company and a Participant, and nothing in this Plan shall confer upon any Participant any right to continued employment with a Participating Company, or to interfere with the right of a Participating Company to discharge a Participant,
with or without cause. 
 9.3. Interests Not Transferable. Except as to withholding of any tax under the laws of the
United States or any state or locality, no benefits under the Plan shall be subject in any manner to alienation, sale, transfer, assignment, pledge, attachment or other legal process, or encumbrance of any kind, and any attempt to do so shall be
void. 
 9.4. Facility of Payment. Any amounts payable hereunder to any person under legal disability or who, in the
judgment of the Plan Administrator, is unable to properly manage his financial affairs, may be paid to the legal representative of such person, or may be applied for the benefit of such person in any manner which the Plan Administrator may select,
and the Plan Administrator and each Participating Company shall be relieved of any further liability for payment of such amounts. 
 9.5. Tax Withholding. A Participating Company shall deduct or “net” from any payments otherwise due under this Plan to a Participant (or beneficiary) such number of Common Units equaling
in value the amount required by law to be withheld for purposes of federal, state or local taxes. 
 9.6. Gender and
Number. Words in the masculine gender shall include the feminine gender, the plural shall include the singular and the singular shall include the plural. 
 9.7. Controlling Law. To the extent not superseded by federal law, the law of the State of New York shall be controlling in all matters relating to the Plan.

 4. I understand that the notional value of a Phantom Unit credited to my Account under the Plan will fluctuate with the Fair
Market Value of a Common Unit, and I am prepared and can afford to lose the entire value of the notional cash balance of my Account under the Plan. 
 5. I hereby further consent to the amendments to and restatement of the Plan by the Board of Directors of the Company made at its meeting on December 14, 2000.
