Exhibit 10.1

 Exhibit 10.1 
 AMENDED AND RESTATED 
 MANAGEMENT CONTINUITY AGREEMENT 

This Amended and Restated Management Continuity Agreement, dated as of December 7, 2012 (“Agreement”), amends and restates
the Management Continuity Agreement, dated as of July 17, 2012 (the “Initial Agreement”), between Union First Market Bankshares Corporation, a Virginia corporation (the “Company”), and Robert M. Gorman (the
“Executive”). 
 This Amended Agreement amends Section 5(c) of the Initial Agreement to remove the ability of the
Executive to terminate his employment during the Window Period (as defined therein) without any reason and still be entitled to receive the severance and other benefits under Section 6(a). 

1. Purpose 
 The Company recognizes that the possibility of a Change in Control exists and the uncertainty and questions that it may raise among management may result in the departure or distraction of management
personnel to the detriment of the Company and its shareholders. Accordingly, the purpose of this Agreement is to encourage the Executive to continue employment with the Company and/or its affiliates or successors in interest by merger or acquisition
after a Change in Control by providing reasonable employment security to the Executive and to recognize the prior service of the Executive in the event of a termination of employment under certain circumstances after a Change in Control. 

2. Term of the Agreement 
 This Agreement will be effective on December 7, 2012 and will expire on December 31, 2014; provided that on January 1, 2015 and on each January 1st thereafter (each such January 1st is referred to as the “Renewal Date”), this Agreement will
be automatically extended for an additional calendar year. This Agreement will not, however, be extended if the Company gives written notice of such non-renewal to the Executive no later than September 30th before the Renewal Date (the original and any extended term of this
Agreement is referred to as the “Change in Control Period”). 
 3. Employment After a Change in Control

 If a Change in Control of the Company (as defined in Section 12) occurs during the Change in Control Period and the
Executive is employed by the Company on the date the Change in Control occurs (the “Change in Control Date”), the Company will continue to employ the Executive in accordance with the terms and conditions of this Agreement for the period
beginning on the Change in Control Date and ending on the third anniversary of such date (the “Employment Period”). If a Change in Control occurs on account of a series of transactions, the Change in Control Date is the date of the last of
such transactions. 

 4. Terms of Employment 

(a) Position and Duties. During the Employment Period, (i) the Executive’s position, authority, duties and
responsibilities will be commensurate in all material respects with the most significant of those held, exercised and assigned to Executive by the Company at any time during the 90-day period immediately preceding the Change in Control Date and
(ii) the Executive’s services will be performed at the location where the Executive was employed immediately preceding the Change in Control Date or any office that is the headquarters of the Company and is less than 35 miles from such
location. 
 (b) Compensation. 
 (i) Base Salary. During the Employment Period, the Executive will receive an annual base salary (the “Annual Base Salary”) at least equal to the base salary paid or payable to the
Executive by the Company and its affiliated companies for the twelve-month period immediately preceding the Change of Control Date. During the Employment Period, the Annual Base Salary will be reviewed at least annually and will be increased at any
time and from time to time as will be substantially consistent with increases in base salary generally awarded in the ordinary course of business to other peer executives of the Company and its affiliated companies. Any increase in the Annual Base
Salary will not serve to limit or reduce any other obligation to the Executive under this Agreement. The Annual Base Salary will not be reduced after any such increase, and the term Annual Base Salary as used in this Agreement will refer to the
Annual Base Salary as so increased. The term “affiliated companies” includes any company controlled by, controlling or under common control with the Company. 

(ii) Annual Bonus. In addition to the Annual Base Salary, the Executive will be awarded for each year ending during
the Employment Period and for which the Executive is employed on the last day of the year an annual bonus (the “Annual Bonus”) in cash at least equal to the average annual bonus paid or payable, including by reason of any deferral, for the
two years immediately preceding the year in which the Change in Control Date occurs. Each such Annual Bonus will be paid no later than two and one-half months after the end of the year for which the Annual Bonus is awarded. 

(iii) Incentive, Savings and Retirement Plans. During the Employment Period, the Executive will be entitled to
participate in all incentive (including stock incentive), savings and retirement, insurance plans, policies and programs applicable generally to other peer executives of the Company and its affiliated companies, but in no event will such plans,
policies and programs provide the Executive with incentive opportunities, savings opportunities and retirement benefit opportunities, in each case, less favorable, in the aggregate, than those provided by the Company and its affiliated companies for
the Executive under such plans, policies and programs as in effect at any time during the six months immediately preceding the Change in Control Date. 

  
 2 

 (iv) Welfare Benefit Plans. During the Employment Period, the
Executive and/or the Executive’s family, as the case may be, will be eligible for participation in and will receive all benefits under welfare benefit plans, policies and programs provided by the Company and its affiliated companies to the
extent applicable generally to other peer executives of the Company and its affiliated companies, but in no event will such plans, policies and programs provide the Executive with benefits that are less favorable, in the aggregate, than the most
favorable of such plans, policies and programs in effect at any time during the six months immediately preceding the Change in Control Date. 
 (v) Fringe Benefits. During the Employment Period, the Executive will be entitled to fringe benefits in accordance with the most favorable plans, policies and programs of the Company and its
affiliated companies in effect for the Executive at any time during the six months immediately preceding the Change in Control Date or, if more favorable to the Executive, as in effect generally from time to time after the Change in Control Date
with respect to other peer executives of the Company and its affiliated companies. 
 (vi) Paid Time Off.
During the Employment Period, the Executive will be entitled to paid time off in accordance with the most favorable plans, policies and programs of the Company and its affiliated companies in effect for the Executive at any time during the six
months immediately preceding the Change in Control Date or, if more favorable to the Executive, as in effect generally from time to time after the Change in Control Date with respect to other peer executives of the Company and its affiliated
companies. 
 5. Termination of Employment Following a Change in Control 

(a) Death or Disability. The Executive’s employment will terminate automatically upon the Executive’s death during the
Employment Period. If the Company determines in good faith that the Disability of the Executive has occurred during the Employment Period, it may terminate the Executive’s employment. For purposes of this Agreement, “Disability” means
the Executive’s inability to perform the essential functions of his position with the Company on a full time basis for 180 consecutive days or a total of at least 240 days in any twelve month period as a result of the Executive’s
incapacity due to physical or mental illness (as determined by an independent physician selected by the Board of the Company). 

(b) Cause. The Company may terminate the Executive’s employment during the Employment Period for Cause. For purposes of this
Agreement, “Cause” means (i) gross incompetence, gross negligence, willful misconduct in office or breach of a material fiduciary duty owed to the Company or any affiliated company; (ii) conviction of or entering of a guilty plea
or a plea of no contest with respect to a felony or a crime of moral turpitude or 

  
 3 

 
commission of an act of embezzlement or fraud against the Company or any affiliated company; (iii) any material breach by the Executive of a material term of this Agreement, including,
without limitation, material failure to perform a substantial portion of his duties and responsibilities hereunder; or (iv) deliberate dishonesty of the Executive with respect to the Company or any affiliated company. 

(c) Good Reason. The Executive’s employment may be terminated during the Employment Period by the Executive for Good Reason.
For purposes of this Agreement, “Good Reason” means: 
 (i) a material reduction in the
Executive’s duties or authority; 
 (ii) a failure by the Company to comply with any of the provisions of
Section 4(b); 
 (iii) the Company’s requiring the Executive to be based at any office or location
other than that described in Section 4(a) (ii); 
 (iv) the failure by the Company to comply with and
satisfy Section 7(b); or 
 (v) the Company fails to honor any term or provision of this Agreement;

 Notwithstanding the above, Good Reason shall not include an isolated, insubstantial and/or inadvertent action not taken in bad faith by the
Company and which is remedied by the Company within a reasonable time after receipt of notice thereof if given by the Executive. 
 (d) Notice of Termination. Any termination during the Employment Period by the Company or by the Executive for Good Reason shall be communicated by written Notice of Termination to the other party
hereto. For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon. 

(e) Date of Termination. “Date of Termination” means (i) if the Executive’s employment is terminated by the
Company for Cause, or by the Executive for Good Reason, the date of receipt of the Notice of Termination or any later date specified therein, as the case may be, (ii) if the Executive’s employment is terminated by the Company other than
for Cause or Disability, the date specified in the Notice of Termination (which shall not be less than 30 nor more than 60 days from the date such Notice of Termination is given), and (iii) if the Executive’s employment is terminated for
Disability, 30 days after Notice of Termination is given, provided that the Executive shall not have returned to the full-time performance of his duties during such 30-day period. 

  
 4 

 6. Compensation Upon Termination 

(a) Termination Without Cause or for Good Reason. The Executive will be entitled to the following benefits if, during the
Employment Period, the Company terminates his employment without Cause or the Executive terminates his employment with the Company or any affiliated company for Good Reason. 

(i) Accrued Obligations. The Accrued Obligations are the sum of: (1) the Executive’s Annual Base Salary
through the Date of Termination at the rate in effect just prior to the time a Notice of Termination is given; (2) the amount, if any, of any incentive or bonus compensation theretofore earned which has not yet been paid; (3) the product
of the Annual Bonus paid or payable, including by reason of deferral, for the most recently completed year and a fraction, the numerator of which is the number of days in the current year through the Date of Termination and the denominator of which
is 365; and (4) any benefits or awards (including both the cash and stock components) which pursuant to the terms of any plans, policies or programs have been earned or become payable, but which have not yet been paid to the Executive (but not
including amounts that previously had been deferred at the Executive’s request, which amounts will be paid in accordance with the Executive’s existing directions). The Accrued Obligations will be paid to the Executive in a lump sum cash
payment within ten days after the Date of Termination; 
 (ii) Salary Continuance
Benefit. The Salary Continuance Benefit is an amount equal to 2.0 times the Executive’s Final Compensation. For purposes of this Agreement, “Final Compensation” means the Annual Base Salary in effect at the Date of Termination,
plus the highest Annual Bonus paid or payable for the two most recently completed years and any amount contributed by the Executive during the most recently completed year pursuant to a salary reduction agreement or any other program that provides
for pre-tax salary reductions or compensation deferrals. The Salary Continuance Benefit will be paid to the Executive in a lump sum cash payment not later than the 45th day following the Date of Termination; 

(iii) Welfare Continuance Benefit. For 24 months following the Date of Termination, the Executive and his
dependents will continue to be covered under all health and dental plans, disability plans, life insurance plans and all other welfare benefit plans (as defined in Section 3(1) of ERISA) (“Welfare Plans”) in which the Executive or his
dependents were participating immediately prior to the Date of Termination (the “Welfare Continuance Benefit”). The Company will pay all or a portion of the cost of the Welfare Continuance Benefit for the Executive and his dependents under
the Welfare Plans on the same basis as applicable, from time to time, to active employees covered under the Welfare Plans and the Executive will pay any additional costs. If participation in any one or more of the Welfare Plans included in the
Welfare Continuance Benefit is not possible under the terms of the Welfare Plan or any provision of law would create an adverse tax effect for the Executive or the Company due to such participation, the Company will provide substantially identical
benefits directly or through an insurance arrangement. The Welfare 

  
 5 

 
Continuance Benefit as to any Welfare Plan will cease if and when the Executive has obtained coverage under one or more welfare benefit plans of a subsequent employer that provides for equal or
greater benefits to the Executive and his dependents with respect to the specific type of benefit. The Executive or his dependents will become eligible for COBRA continuation coverage as of the date the Welfare Continuance Benefit ceases for all
health and dental benefits. 
 (b) Death. If the Executive dies during the Employment Period, this Agreement will
terminate without any further obligation on the part of the Company under this Agreement, other than for (i) payment of the Accrued Obligations and six months of the Executive’s Base Salary (which shall be paid to the Executive’s
beneficiary designated in writing or his estate, as applicable, in a lump sum cash payment within 30 days of the date of death); (ii) the timely payment or provision of the Welfare Continuance Benefit to the Executive’s spouse and other
dependents for 24 months following the date of death; and (iii) the timely payment of all death and retirement benefits pursuant to the terms of any plan, policy or arrangement of the Company and its affiliated companies. 

(c) Disability. If the Executive’s employment is terminated because of the Executive’s Disability during the Employment
Period, this Agreement will terminate without any further obligation on the part of the Company under this Agreement, other than for (i) payment of the Accrued Obligations and six months of the Executive’s Base Salary (which shall be paid
to the Executive in a lump sum cash payment within 30 days of the Date of Termination; (ii) the timely payment or provision of the Welfare Continuance Benefit for 24 months following the Date of Termination; and (iii) the timely payment of
all disability and retirement benefits pursuant to the terms of any plan, policy or arrangement of the Company and its affiliated companies. 
 (d) Cause; Other than for Good Reason. If the Executive’s employment is terminated for Cause during the Employment Period, this Agreement will terminate without further obligation to the
Executive other than the payment to the Executive of the Annual Base Salary through the Date of Termination, plus the amount of any compensation previously deferred by the Executive. If the Executive terminates employment during the Employment
Period, excluding a termination for Good Reason, this Agreement will terminate without further obligation to the Executive other than for the Accrued Obligations (which will be paid in a lump sum in cash within 30 days of the Date of Termination)
and any other benefits to which the Executive may be entitled pursuant to the terms of any plan, program or arrangement of the Company and its affiliated companies. 
 (e) Maximum Benefit. No amounts will be payable and no benefits will be provided under this Agreement to the extent that such payments or benefits, together with other payments or benefits under
other plans, agreements or arrangements, would make the Executive liable for the payment of an excise tax under Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”), or any successor provision. The amounts
otherwise payable and the benefits otherwise to be provided under this Agreement shall be reduced in a manner determined by the Company (by the minimum possible amount) that is consistent with the requirements of Section 409A of the Code until
no 

  
 6 

 
amount payable to the Executive will be subject to such excise tax. All calculations and determinations under this Section 6(e) shall be made by an independent accounting firm or independent
tax counsel appointed by the Company (the “Tax Advisor”) whose determinations shall be conclusive and binding on the Company and the Executive for all purposes. The Tax Advisor may rely on reasonable, good faith assumptions and
approximations concerning the application of Section 280G and Section 4999 of the Code. The Company shall bear all costs of the Tax Advisor. 
 7. Binding Agreement; Successors 
 (a) This Agreement will be binding upon
and inure to the benefit of the Executive (and his personal representative), the Company and any successor organization or organizations which shall succeed to substantially all of the business and property of the Company, whether by means of
merger, consolidation, acquisition of all or substantially of all of the assets of the Company or otherwise, including by operation of law. 
 (b) The Company will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of the Company to assume
expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. 
 (c) For purposes of this Agreement, the term “Company” includes any subsidiaries of the Company and any corporation or other entity which is the surviving or continuing entity in respect of any
merger, consolidation or form of business combination in which the Company ceases to exist; provided, however, that for purposes of determining whether a Change in Control has occurred herein, the term “Company” refers to Union First
Market Bankshares Corporation or its successors. 
 8. Fees and Expenses; Mitigation 

(a) The Company will pay or reimburse the Executive for all costs and expenses, including without limitation court costs and reasonable
attorneys’ fees, incurred by the Executive (i) in contesting or disputing any termination of the Executive’s employment or (ii) in seeking to obtain or enforce any right or benefit provided by this Agreement, in each case
provided the Executive is the prevailing party in a proceeding brought in a court of competent jurisdiction. The Company shall reimburse the foregoing costs on a current basis after the Executive submits a claim for reimbursement with the proper
documentation of the costs and expenses, provided that no expense will be reimbursed after the end of the year following the year in which the expense is incurred. 
 (b) The Executive shall not be required to mitigate the amount of any payment the Company becomes obligated to make to the Executive in connection with this Agreement, by seeking other employment or
otherwise. Except as specifically provided above with respect to the Welfare Continuance Benefit, the amount of any payment provided for in Section 6 shall not be reduced, offset or subject to recovery by the Company by reason of any
compensation earned by the Executive as the result of employment by another employer after the Date of Termination, or otherwise. 

  
 7 

 9. No Employment Contract 

Nothing in this Agreement will be construed as creating an employment contract between the Executive and the Company prior to Change in
Control. 
 10. Continuance of Welfare Benefits Upon Death 

If the Executive dies while receiving a Welfare Continuation Benefit, the Executive’s spouse and other dependents will continue to be
covered under all applicable Welfare Plans during the remainder of the 24-month coverage period. The Executive’s spouse and other dependents will become eligible for COBRA continuation coverage for health and dental benefits at the end of such
24-month period. 
 11. Notice 
 Any notices and other communications provided for by this Agreement will be sufficient if in writing and delivered in person, or sent by registered or certified mail, postage prepaid (in which case notice
will be deemed to have been given on the third day after mailing), or by overnight delivery by a reliable overnight courier service (in which case notice will be deemed to have been given on the day after delivery to such courier service). Notices
to the Company shall be directed to the Secretary of the Company, with a copy directed to the Chairman of the Board of the Company. Notices to the Executive shall be directed to his last known address. 

12. Definition of a Change in Control 
 No benefits shall be payable hereunder unless there shall have been a Change in Control of the Company as set forth below. For purposes of this Agreement, a “Change in Control” means:

 (a) The acquisition by any Person of beneficial ownership of 20% or more of the then outstanding shares of common stock of
the Company, provided that an acquisition directly from the Company (excluding an acquisition by virtue of the exercise of a conversion privilege) shall not constitute a Change in Control; 

(b) Individuals who constitute the Board on the date of this Agreement (the “Incumbent Board”) cease to constitute a majority
of the Board, provided that any director whose nomination was approved by a vote of at least two-thirds of the directors then comprising the Incumbent Board will be considered a member of the Incumbent Board, but excluding any such individual whose
initial assumption of office is in connection with an actual or threatened election contest relating to the election of the directors of the Company; 

  
 8 

 (c) Approval by the shareholders of the Company of a reorganization, merger, share exchange
or consolidation (a “Reorganization”), provided that shareholder approval of a Reorganization will not constitute a Change in Control if, upon consummation of the Reorganization, each of the following conditions is satisfied: 

(i) more than 50% of the then outstanding shares of common stock of the corporation resulting from the Reorganization is
beneficially owned by all or substantially all of the former shareholders of the Company in substantially the same proportions as their ownership existed in the Company immediately prior to the Reorganization; 

(ii) no Person beneficially owns 20% or more of either (1) the then outstanding shares of common stock of the
corporation resulting from the transaction or (2) the combined voting power of the then outstanding voting securities of such corporation entitled to vote generally in the election of directors; and 

(iii) at least a majority of the members of the board of directors of the corporation resulting from the Reorganization
were members of the Incumbent Board at the time of the execution of the initial agreement providing for the Reorganization. 

(d) Approval by the shareholders of the Company of a complete liquidation or dissolution of the Company, or of the sale or other
disposition of all or substantially all of the assets of the Company. 
 (e) For purposes of this Agreement, “Person”
means any individual, entity or group (within the meaning of Section 13(d)(3) of the Securities Exchange Act of 1934 (the “Exchange Act”), other than any employee benefit plan (or related trust) sponsored or maintained by the Company
or any affiliated company, and “beneficial ownership” has the meaning given the term in Rule 13d-3 under the Exchange Act. 
 13. Confidentiality 
 The Executive will hold in a fiduciary capacity for
the benefit of the Company all secret or confidential information, knowledge or data relating to the Company or any of its affiliated companies and their respective businesses, which was obtained by the Executive during the Executive’s
employment by the Company or any of its affiliated companies and which will not be or become public knowledge. After termination of the Executive’s employment with the Company, the Executive will not, without the prior written consent of the
Company or except as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than the Company and those designated by it. In no event shall an asserted violation of the
provisions of this Section 13 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under this Agreement. 

  
 9 

 14. Miscellaneous 

No provision of this Agreement may be amended, modified, waived or discharged unless such amendment, modification, waiver or discharge is
agreed to in a writing signed by the Executive and the Chairman of the Board, Chief Executive Officer, or President of the Company. This Agreement replaces and supersedes the Initial Agreement, which is hereby terminated and is without any further
legal force or effect. No waiver by either party hereto at any time of any breach by the other party hereto of, or of compliance with, any condition or provision of this Agreement to be performed by such other party shall be deemed a waiver of
similar or dissimilar provisions or conditions at the same or at any prior or subsequent time. No agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by either party that are
not expressly set forth in this Agreement. 
 15. Governing Law 

The validity, interpretation, construction and performance of this Agreement shall be governed by the laws of the Commonwealth of Virginia
without reference to its conflicts of laws principles. 
 16. Validity 

The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other
provision of this Agreement, which shall remain in full force and effect. 
 17. Deferred Compensation Omnibus Provision.

 (a) It is intended that payments and benefits under this Agreement that are considered to be deferred compensation subject to
Section 409A of the Code shall be provided and paid in a manner, and at such time and in such form, as complies with the applicable requirements of Section 409A of the Code to avoid the unfavorable tax consequences provided for therein for
non-compliance. Notwithstanding any other provision of this Agreement, the Company’s Compensation Committee or Board of Directors is authorized to amend this Agreement, to amend or void any election made by the Executive under this Agreement
and/or to delay the payment of any monies and/or provision of any benefits in such manner as may be determined by it to be necessary or appropriate to comply with Section 409A of the Code. For purposes of this Agreement, all rights to payments
and benefits hereunder shall be treated as rights to receive a series of separate payments and benefits to the fullest extent allowed by Section 409A of the Code. 
 (b) If the Executive is deemed on the date of separation of service with the Company to be a “specified employee,” as defined in Section 409A(a)(2)(B) of the Code, then payment of any
amount or provision of any benefit under this Agreement that is considered deferred compensation subject to Section 409A of the Code shall not be made or provided prior to the earlier of (A) the expiration of the six-month period measured
from the date of separation of service or (B) the date of death (the “409A Deferral Period”). 

  
 10 

 (c) In the case of benefits that are subject to Section 409A of the Code, the Executive
may pay the cost of benefit coverage, and thereby obtain benefits, during the 409A Deferral Period and then be reimbursed by the Company when the 409A Deferral Period ends. On the first day after the end of the 409A Deferral Period, all payments
delayed pursuant to this Section 17 (whether they would have otherwise been payable in a single lump sum or in installments in the absence of such deferral) shall be paid or reimbursed to the Executive in a lump sum, and any remaining payments
and benefits due under this Agreement shall be paid or provided as originally scheduled. 
 (d) “Termination of
employment” shall have the same meaning as “separation of service,” as that phrase is defined in Section 409A of the Code (taking into account all rules and presumptions provided for in the Section 409A regulations).

 18. Clawback. The Executive agrees that any incentive based compensation or award that he receives, or has received,
from the Company or its Affiliates under this Agreement or otherwise, will be subject to clawback by the Company as may be required by applicable law or stock exchange listing requirement and on such basis as the Board of Directors of the Company
determines, but in no event with a look-back period of more than three years, unless required by applicable law or stock exchange listing requirement.

 Execution Version 
 SECOND AMENDMENT TO REVOLVING CREDIT
AGREEMENT 
 THIS SECOND AMENDMENT TO REVOLVING CREDIT AGREEMENT (this “Amendment”), is
made and entered into as of December 7, 2012, by and among ATMOS ENERGY CORPORATION, a Texas and Virginia corporation (the “Borrower”), the several banks and other financial institutions from time to time party hereto
(collectively, the “Lenders”) and THE ROYAL BANK OF SCOTLAND PLC, in its capacity as Administrative Agent for the Lenders (the “Administrative Agent”). 

W I T N E S S E T H: 
 WHEREAS, the Borrower, the Lenders and the Administrative Agent are parties to a certain Revolving Credit Agreement, dated as of May 2, 2011 (as amended, restated, supplemented or otherwise modified
from time to time, the “Credit Agreement”; capitalized terms used herein and not otherwise defined shall have the meanings assigned to such terms in the Credit Agreement), pursuant to which the Lenders have made certain
financial accommodations available to the Borrower; 
 WHEREAS, the Borrower has notified the Administrative Agent and each of
the Lenders that the Borrower proposes to increase the Aggregate Commitment Amount under the Credit Agreement by the amount of $200,000,000 which increase shall be made without using the existing $250,000,000 uncommitted incremental facility set
forth in Section 2.21 of the Credit Agreement; 
 WHEREAS, certain Lenders have agreed to increase their Commitments, and
certain other banks, financial institutions and lenders (the “New Lenders”) have agreed to join the Credit Agreement and to provide additional Commitments, all as requested by the Borrower and the Credit Agreement will
continue to contemplate an up to $250,000,000 uncommitted incremental facility set forth in Section 2.21 of the Revolving Credit Agreement that may be used in addition to the incremental Commitments provided below; 

WHEREAS, the Borrower has also requested that the Lenders and the Administrative Agent amend certain provisions of the Credit Agreement,

New Lenders are several and not joint commitments and obligations of such Lender. Immediately after giving effect to this Amendment, the outstanding Borrowings shall be reallocated ratably based upon the Commitments as set forth on Schedule
II. Each of the parties hereto acknowledges and agrees that the foregoing increase in the Commitments is independent of Section 2.21 of the Credit Agreement, and the Borrower retains the right to further increase the Commitments by up to
$250,000,000 after the Second Amendment Date on the terms set forth in Section 2.21 of the Credit Agreement.

counterparts, each of which shall be deemed an original and all of which, taken together, shall be deemed to constitute one and the same instrument. Delivery of an executed counterpart of this Amendment by facsimile transmission or by electronic
mail in pdf form shall be as effective as delivery of a manually executed counterpart hereof. 
 11. Binding
Nature. This Amendment shall be binding upon and inure to the benefit of the parties hereto, their respective successors, successors-in-titles, and assigns. 
 12. Entire Understanding. This Amendment sets forth the entire understanding of the parties with respect to the matters set forth herein, and shall supersede any prior negotiations or
