Change in Control Agreement

 EXHIBIT 10.1 
 AGREEMENT 
 THIS AGREEMENT is made as of the 13th day of March, 2006 by and between Armstrong World Industries, Inc., a Pennsylvania corporation (the “Company”), and Donald A. McCunniff (the
“Executive”). 
 WHEREAS, the Board considers it essential to the best interests of the Company to foster the continued employment of key
management personnel; and 
 WHEREAS, the Board recognizes that, as is the case with many publicly held corporations, the possibility of a Change in Control
exists and that such possibility, and the uncertainty and questions which it may raise among management, may result in the departure or distraction of management personnel to the detriment of the Company; and 
 WHEREAS, the Board has determined that appropriate steps should be taken to reinforce and encourage the continued attention and dedication of members of the
Company’s management, including the Executive, to their assigned duties without distraction in the face of potentially disturbing circumstances arising from the possibility of a Change in Control; 
 NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the Company and the Executive hereby agree as follows: 
 1. Defined Terms. The definitions of capitalized terms used in this Agreement are provided in the last Section hereof. 
 2. Term of Agreement. This Agreement shall commence on the date hereof and shall continue in effect through September 30, 2008; provided,
however, that commencing on October 1, 2006 and each October 1 thereafter, the term of this Agreement shall automatically be extended for one additional year unless, not later than June 30 of that year, the Company or the
Executive shall have given notice not to extend this Agreement or a Change in Control shall have occurred prior to such October 1; and further provided, however, that if a Change in Control shall have occurred during the
term of this Agreement, this Agreement shall continue in effect for a period of not less than thirty-six (36) months beyond the month in which such Change in Control occurred. 
 3. Company’s Covenants Summarized. In order to induce the Executive to remain in the employ of the Company and in consideration of the Executive’s covenants set forth in Section 4 hereof, the
Company agrees, under the conditions described herein, to pay the Executive the Severance Payments and the other payments and benefits described herein. Except as provided in Section 10.1 hereof, no amount or benefit shall be payable under this
Agreement unless there shall have been (or, under the terms of 

  

 - 1 - 

 
the second sentence of Section 6.1 hereof, there shall be deemed to have been) a termination of the Executive’s employment with the Company
following a Change in Control and during the term of this Agreement. This Agreement shall not be construed as creating an express or implied contract of employment and, except as otherwise agreed in writing between the Executive and the Company, the
Executive shall not have any right to be retained in the employ of the Company. 
 4. The Executive’s Covenants. The Executive agrees that,
subject to the terms and conditions of this Agreement, in the event of a Potential Change in Control during the term of this Agreement, the Executive will remain in the employ of the Company until the earliest of (i) a date which is six
(6) months after the date of such Potential Change in Control, (ii) the date of a Change in Control, (iii) the date of termination by the Executive of the Executive’s employment for Good Reason or by reason of death or
Disability, or (iv) the termination by the Company of the Executive’s employment for any reason. 
 5. Compensation Other Than Severance
Payments. 
 5.1. Following a Change in Control and during the term of this Agreement, during any period that the Executive fails to perform the
Executive’s full-time duties with the Company as a result of incapacity due to physical or mental illness, the Company shall pay the Executive’s full salary to the Executive at the rate in effect at the commencement of any such period,
together with all compensation and benefits payable to the Executive under the terms of any compensation or benefit plan, program or arrangement maintained by the Company during such period, until the Executive’s employment is terminated by the
Company for Disability. 
 5.2. If the Executive’s employment shall be terminated for any reason following a Change in Control and during the term of
this Agreement, the Company shall pay the Executive’s full salary to the Executive through the Date of Termination at the rate in effect immediately prior to the Change in Control or at the time the Notice of Termination is given, whichever is
greater, together with all compensation and benefits to which the Executive is entitled in respect of all periods preceding the Date of Termination under the terms of the Company’s compensation and benefit plans, programs or arrangements.

 5.3. If the Executive’s employment shall be terminated for any reason following a Change in Control and during the term of this Agreement, the
Company shall pay to the Executive the Executive’s normal post-termination compensation and benefits as such payments become due. Such post-termination compensation and benefits shall be determined under, and paid in accordance with, the
Company’s retirement, insurance and other compensation or benefit plans, programs and arrangements as in effect immediately prior to the Change in Control or, if more favorable to the Executive, as in effect immediately prior to the Date of
Termination.

 6. Severance Payments. 
 6.1. The Company shall pay the Executive the payments described in this Section 6.1 (the “Severance Payments”) upon the termination of the Executive’s employment following a Change in Control and during the term of this
Agreement, in addition to any payments and benefits to which the Executive is entitled under Section 5 and 8 hereof, unless such termination is (i) by the Company for Cause, (ii) by reason of death or Disability, or (iii) by the
Executive without Good Reason. For purposes of this Agreement, the Executive’s employment shall be deemed to have been terminated by the Company without Cause or by the Executive with Good Reason following a Change in Control if (i) the
Executive’s employment is terminated without Cause prior to a Change in Control which actually occurs during the term of this Agreement and such termination was at the request or direction of a Person who has entered into an agreement with the
Company the consummation of which would constitute a Change in Control, (ii) the Executive terminates his employment with Good Reason prior to a Change in Control which actually occurs during the term of this Agreement and the circumstance or
event which constitutes Good Reason occurs at the request or direction of such Person, (iii) the Executive’s employment is terminated by the Company without Cause or by the Executive for Good Reason prior to a Change in Control and the
Executive reasonably demonstrates that such termination is otherwise in connection with or in anticipation of a Change in Control which actually occurs during the term of this Agreement; provided that any termination of the Executive’s
employment by the Company without Cause or by the Executive for Good Reason within the six (6) month period immediately preceding a Change in Control which actually occurs during the term of this Agreement shall be presumed to be a termination
by the Company without Cause or by the Executive for Good Reason following a Change in Control, or (iv) the Executive’s employment is terminated without Cause after a Potential Change in Control of the type described in paragraph
(I) of the definition of “Potential Change in Control”. 
 (A) In lieu of any further salary payments to the Executive for
periods subsequent to the Date of Termination and in lieu of any severance benefit otherwise payable to the Executive, the Company shall pay to the Executive a lump sum severance payment, in cash, equal to three (3) times the sum of
(i) the higher of the Executive’s annual base salary in effect immediately prior to the occurrence of the event or circumstance upon which the Notice of Termination is based or the Executive’s annual base salary in effect immediately
prior to the Change in Control (the “Change in Control Salary”), and (ii) the higher of the highest annual bonus earned by the Executive pursuant to any annual bonus or incentive plan maintained by the Company in respect of the three
(3) years immediately preceding that year in which the Date of Termination occurs or the highest annual bonus so earned in respect of the three (3) years immediately preceding that in which the Change in Control occurs (the “Change in
Control Bonus”). If the Executive’s termination occurs prior to December 31, 2007, the Executive’s Change in Control Bonus shall be the highest of his current and any previous target annualized incentive award and any actual
award received. 
  

 - 3 - 

 (B) Notwithstanding any provision of any annual incentive plan to the contrary, the Company shall pay to
the Executive a lump sum amount, in cash, equal to a pro rata portion to the Date of Termination of the value of the target incentive award under such plan for the then uncompleted period under such plan, calculated by multiplying the
Executive’s target award by the fraction obtained by dividing the number of full months and any fractional portion of a month during such performance award period through the Date of Termination by the total number of months contained in such
performance award period. 
 (C) For the thirty-six (36) month period immediately following the Date of Termination, the Company shall
arrange to provide the Executive (which includes the Executive’s eligible dependents for purposes of this paragraph (C)) with life, disability, accident and health insurance benefits substantially similar to those which the Executive was
receiving immediately prior to the Notice of Termination (without giving effect to any amendment to such benefits made subsequent to the earlier of a Potential Change in Control or a Change in Control which amendment adversely affects in any manner
the Executive’s entitlement to or the amount of such benefits); provided, however, that, unless the Executive consents to a different method, such health insurance benefits shall be provided through a third-party insurer. Benefits
otherwise receivable by the Executive pursuant to this Section 6.1(C) shall be reduced to the extent comparable benefits (including continued coverage for any preexisting medical condition of any person covered by the benefits provided to the
Executive and his eligible dependents immediately prior to the Notice of Termination) are actually received by or made available to the Executive by a subsequent employer without cost during the thirty-six (36) month period following the
Executive’s termination of employment (and any such benefits actually received by or made available to the Executive shall be reported to the Company by the Executive). 
 (D) If the Executive would have become entitled to benefits under the Company’s post-retirement health care or life insurance plans (as in effect
immediately prior to a Potential Change in Control, the Change in Control or the Date of Termination, whichever is most favorable to the Executive) had the Executive’s employment terminated at any time during the period of thirty-six
(36) months after the Date of Termination, the Company shall provide such post-retirement health care or life insurance benefits to the Executive (subject to any employee contributions required under the terms of such plans at the level in
effect immediately prior to the Change in Control or the Date of Termination, whichever is more favorable to the Executive) commencing on the later of (i) the date that such coverage would have first become available or (ii) the date that
benefits described in subsection (C) of this Section 6.1 terminate. 
 (E) The Company will pay the Executive, at a daily salary
rate calculated from the higher of the Executive’s annual base salary in effect immediately prior to the occurrence of the event or circumstance upon which the Notice of Termination is 

  

 - 4 - 

 
based or the Executive’s annual base salary in effect immediately prior to the Change in Control, an amount equal to all unused vacation days which
would have been earned had the Executive continued employment through December 31 of the year in which the Date of Termination occurs. 
 (F) The Company shall pay the reasonable fees and expenses of a full service nationally recognized executive outplacement firm until the earlier of the date the Executive secures new employment or the date which is thirty-six
(36) months following the Executive’s Date of Termination; provided, that in no event shall the aggregate amount of such payment be greater than 20% of the Executive’s Change in Control Salary. 
 6.2. (A) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Company
to or for the benefit of the Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise) (a “Payment”) would be subject to the excise tax imposed by Section 4999 of the Code
or any interest or penalties are incurred by the Executive with respect to the excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the “Excise Tax”), then the Executive
shall be entitled to receive an additional payment (a “Gross-Up Payment”) in an amount such that after payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including, without
limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed on the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments.

 (B) Subject to the provisions of Section 6.2(C), all determinations required to be made under this Section 6.2, including whether
and when a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall be made by a qualified accounting firm designated by the Company (the “Accounting Firm”) which shall provide detailed supporting calculations both to
the Company and the Executive within fifteen (15) business days after there has been a Payment, or such earlier time as requested by the Company. In the event that the Accounting Firm is serving as accountant or auditor for the individual,
entity or group effecting the Change in Control, the Company shall appoint another qualified accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees
and expenses of the Accounting Firm shall be borne solely by the Company. Any Gross-Up Payment, as determined pursuant to this Section 6, shall be paid by the Company to the Executive within five days of the receipt of the Accounting
Firm’s determination. Any determination by the Accounting Firm shall be binding upon the Company and the Executive. As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial 

  

 - 5 - 

 
determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been made by the Company that should have been made
(“Underpayment”), consistent with the calculations required to be made hereunder. In the event that the Company exhausts its remedies pursuant to Section 6.2(C) and the Executive thereafter is required to make a payment of any Excise
Tax, the Accounting Firm shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to or for the benefit of the Executive. 
 (C) The Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the
Company of a Gross-Up Payment or Underpayment. Such notification shall be given as soon as practicable but no later than ten (10) business days after the Executive is informed in writing of such claim and shall apprise the Company of the nature
of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which the Executive gives such notice to the Company (or such shorter
period ending on the date any payment of taxes with respect to such claim is due). If the Company notifies the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall: 
 (i) give the Company any information reasonably requested by the Company relating to such claim; 
 (ii) take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without
limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company; 
 (iii) cooperate
with the Company in good faith in order effectively to contest such claim; and 
 (iv) permit the Company to participate in any proceedings
relating to such claim; 
 provided, however, that the Company shall bear and pay directly all costs and expenses (including additional
interest and penalties) incurred in connection with such contest and shall indemnify and hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result
of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 6.2(C), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue
or forego any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct the Executive to pay the tax claimed and sue for a refund or contest
the claim in any permissible manner, and the Executive agrees to prosecute such contest to a 

  

 - 6 - 

 
determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine;
provided, however, that if the Company directs the Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to the Executive, on an interest-free basis, and shall indemnify and hold the
Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further
provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore,
the Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment or Underpayment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue
raised by the Internal Revenue Service or any other taxing authority. 
 (D) If, after the receipt by the Executive of an amount advanced by
the Company pursuant to Section 6.2(C), the Executive becomes entitled to receive any refund with respect to such claim, the Executive shall (subject to the Company’s complying with the requirements of Section 6.2(C)) promptly pay to
the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Executive of an amount advanced by the Company pursuant to Section 6.2(C), a determination
is made that the Executive shall not be entitled to any refund with respect to such claim and the Company does not notify the Executive in writing of its intent to contest such denial of refund prior to the expiration of 30 days after such
determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of Gross-Up Payment required to be paid. 
 6.3. The payments provided for in subsections (A), (B) and (E) of Section 6.1 hereof shall be made not later than the thirtieth (30th) day following
the Date of Termination; provided, however, that if the amounts of such payments cannot be finally determined on or before such day, the Company shall pay to the Executive on such day an estimate, as determined in good faith by
the Executive of the minimum amount of such payments to which the Executive is clearly entitled and shall pay the remainder of such payments (together with interest at 120% of the rate provided in Section 1274(b)(2)(B) of the Code) as
soon as the amount thereof can be determined but in no event later than the ninetieth (90th) day after the Date of Termination; provided, however, that in the event the Executive becomes entitled to Severance Payments pursuant to the
second sentence of Section 6.1 (except for a termination occurring with respect to clause (iv) of such sentence, which shall be paid as set forth above) such payments shall be due and payable within thirty (30) days following the
actual Change in Control that triggered the Severance Payments. In the event that the amount of the estimated payments 

  

 - 7 - 

 
exceeds the amount subsequently determined to have been due, such excess shall constitute a loan by the Company to the Executive, payable on the fifth
(5th) business day after demand by the Company (together with interest at 120% of the rate provided in Section 1274(b)(2)(B) of the Code). In the event the Company should fail to pay when due the amounts described in subsections (A),
(B) and (E) of Section 6.1 hereof, the Executive shall also be entitled to receive from the Company an amount representing interest on any unpaid or untimely paid amounts from the due date, as determined under this Section 6.3
(without regard to any extension of the Date of Termination pursuant to Section 7.3 hereof), to the date of payment at a rate equal to 120% of the rate provided in Section 1274(b)(2)(B) of the Code. 
 6.4. The Company also shall pay to the Executive all legal fees and expenses incurred by the Executive in disputing in good faith any issue hereunder relating to the
termination of the Executive’s employment, in seeking in good faith to obtain or enforce any benefit or right provided by this Agreement or in connection with any tax audit or proceeding to the extent attributable to the application of
Section 4999 of the Code to any payment or benefit provided hereunder. Such payments shall be made within five (5) business days after delivery of the Executive’s written requests for payment accompanied with such evidence of fees and
expenses incurred as the Company reasonably may require. 
 7. Termination Procedures and Compensation During Dispute. 
 7.1. Notice of Termination. After a Potential Change in Control or, if there is no Potential Change in Control, after a Change in Control and during the term of
this Agreement, any purported termination of the Executive’s employment (other than by reason of death) shall be communicated by written Notice of Termination from one party hereto to the other party hereto in accordance with Section 11
hereof. 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 and shall set forth in reasonable detail the facts and
circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated. Further, a Notice of Termination for Cause is required to include a copy of a resolution duly adopted by the affirmative
vote of not less than three-quarters (3/4) of the entire membership of the Board at a meeting of the Board which was called and held for the purpose of considering such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive’s counsel, to be heard before the Board) finding that, in the good-faith opinion of the Board, the Executive was guilty of conduct set forth in clause (i) or (ii) of the definition of
Cause herein, and specifying the particulars thereof in detail. 
 7.2. Date of Termination. “Date of Termination,” with respect to any
purported termination of the Executive’s employment after a Change in Control and during the term of this Agreement, shall mean (i) if the Executive’s employment is terminated for Disability, thirty (30) days after Notice of
Termination is given (provided that the Executive shall not have returned to the full-time performance of the Executive’s duties 

  

 - 8 - 

 
during such thirty (30) day period), and (ii) if the Executive’s employment is terminated for any other reason, the date specified in the
Notice of Termination (which, in the case of a termination by the Company, shall not be less than thirty (30) days (except in the case of a termination for Cause) and, in the case of a termination by the Executive, shall not be less than
fifteen (15) days nor more than sixty (60) days, respectively, from the date such Notice of Termination is given). 
 7.3. Dispute Concerning
Termination. If within fifteen (15) days after any Notice of Termination is given, or, if later, prior to the Date of Termination (as determined without regard to this Section 7.3), the party receiving such Notice of Termination
notifies the other party that a dispute exists concerning the termination, the Date of Termination shall be extended until the date on which the dispute is finally resolved, either by mutual written agreement of the parties or by a final judgment,
order or decree of an arbitrator or a court of competent jurisdiction (which is not appealable or with respect to which the time for appeal therefrom has expired and no appeal has been perfected); provided, however, that the Date of
Termination shall be extended by a notice of dispute given by the Executive only if such notice is given in good faith and the Executive pursues the resolution of such dispute with reasonable diligence. 
 7.4. Compensation During Dispute. If a purported termination occurs following a Change in Control and during the term of this Agreement and the Date of
Termination is extended in accordance with Section 7.3 hereof, the Company shall continue to pay the Executive the full compensation in effect when the notice giving rise to the dispute was given (including, but not limited to, salary) and
continue the Executive as a participant in all compensation, benefit and insurance plans in which the Executive was participating when the notice giving rise to the dispute was given, until the Date of Termination, as determined in accordance with
Section 7.3 hereof. Amounts paid under this Section 7.4 are in addition to all other amounts due under this Agreement and shall not be offset against or reduce any other amounts due under this Agreement. 
 8. Acceleration of Certain Stock-Based Benefits. 
 (A) Upon the
occurrence of a Change in Control, all unvested options with respect to the Company’s stock held by the Executive shall vest and become immediately exercisable and will be exercisable for a period ending on the later of (i) the fifth
anniversary of such Change in Control or (ii) the last date that such option would otherwise be exercisable under the terms of the option agreement or the plan pursuant to which such option was granted; provided, that in no event shall any
option be exercisable after the expiration of the original term of the option. 
 (B) Upon the occurrence of a Change in Control, all unearned performance
restricted shares held by the Executive under the Company’s Stock Plan shall be deemed to have been earned to the maximum extent permitted under the Stock Plan for any performance period not then completed and all earned but unvested
performance restricted shares, including those deemed to be earned pursuant to this sentence, and all 

  

 - 9 - 

 
unvested restricted stock awards shall immediately vest and the restrictions on all shares subject to restriction shall lapse. 
 (C) For purposes of the Stock Plan and any stock option plan pursuant to which any stock options, performance restricted shares or restricted stock awards have been
issued, this Agreement, which has been approved by the Management Development and Compensation Committee of the Board, shall constitute an amendment of the agreement or other instruments pursuant to which such stock options, performance restricted
shares and restricted stock awards were issued in accordance with the terms of such plans. Notwithstanding the foregoing, in the event that this Section 8(C) is determined for any reason to be inconsistent with the terms of any plan pursuant to
which such stock options, performance restricted shares and restricted stock awards were issued, the terms of this Agreement shall supersede the terms of such plan. 
 9. No Mitigation. The Company agrees that, if the Executive’s employment with the Company terminates during the term of this Agreement, the Executive is not required to seek other employment or to attempt
in any way to reduce any amounts payable to the Executive by the Company pursuant to Section 6 hereof or Section 7.4 hereof. Further, the amount of any payment or benefit provided for in this Agreement (other than Section 6.1(C)
hereof) shall not be reduced by any compensation earned by the Executive as the result of employment by another employer, by retirement benefits, by offset against any amount claimed to be owed by the Executive to the Company, or otherwise.

 10. Successors; Binding Agreement. 
 10.1. In addition
to any obligations imposed by law upon any successor to the Company, 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 expressly assume 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. Failure of the Company to obtain such assumption
and agreement prior to the effectiveness of any such succession shall be a breach of this Agreement and shall entitle the Executive to compensation from the Company in the same amount and on the same terms as the Executive would be entitled to
hereunder if the Executive were to terminate the Executive’s employment for Good Reason after a Change in Control, except that, for purposes of implementing the foregoing, the date on which any such succession becomes effective shall be deemed
the Date of Termination. 
 10.2. This Agreement shall inure to the benefit of and be enforceable by the Executive’s personal or legal representatives,
executors, administrators, successors, heirs, distributees, devisees and legatees. If the Executive shall die while any amount would still be payable to the Executive hereunder (other than amounts which, by their terms, terminate upon the death of
the Executive) if the Executive had continued to live, all such amounts, unless otherwise provided herein, shall be paid in accordance with the 

  

 - 10 - 

 
terms of this Agreement to the executors, personal representatives or administrators of the Executive’s estate. 
 11. Notices. For the purpose of this Agreement, notices and all other communications provided for in the Agreement shall be in writing and shall be deemed to have
been duly given when delivered or mailed by United States registered mail, return receipt requested, postage prepaid, addressed, if to the Executive, to the address shown for the Executive in the personnel records of the Company and, if to the
Company, to the address set forth below, or to such other address as either party may have furnished to the other in writing in accordance herewith, except that notice of change of address shall be effective only upon actual receipt: 
  

			
	 To the Company:
	  	Armstrong World Industries, Inc.
		  	2500 Columbia Avenue
		  	Lancaster, Pennsylvania 17603
		  	Attention: General Counsel

 12. Miscellaneous. No provision of this Agreement may be modified, waived or discharged unless such waiver,
modification or discharge is agreed to in writing and signed by the Executive and such officer as may be specifically designated by the Board. No waiver by either party hereto at any time of any breach by the other party hereto of, or of any lack 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. This Agreement supersedes
any other agreements or representations, oral or otherwise, express or implied, with respect to the subject matter hereof which have been made by either party. The validity, interpretation, construction and performance of this Agreement shall be
governed by the laws of the Commonwealth of Pennsylvania. All references to sections of the Exchange Act or the Code shall be deemed also to refer to any successor provisions to such sections. Any payments provided for hereunder shall be paid net of
any applicable withholding required under federal, state or local law and any additional withholding to which the Executive has agreed. The obligations of the Company and the Executive under Sections 6 and 7 hereof shall survive the expiration of
the term of this Agreement. If the Executive elects not to enter into this Agreement, he will continue to be eligible for such change in control benefits as may be provided at the time of his termination under the Company’s plans. The Executive
agrees that this Agreement replaces the severance benefits to which he may otherwise be entitled to under such plans, the Executive’s employment agreement and the Company’s Severance Pay Plan for salaried employees. The Company agrees that
it will not argue in any form for any purpose that this Agreement constitutes an “employee benefit plan” within the meaning of Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended. 
  

 - 11 - 

 13. 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. 
 14. Counterparts. This Agreement may be
executed in several counterparts, each of which shall be deemed to be an original but all of which together will constitute one and the same instrument. 
 15. Settlement of Disputes; Arbitration. All claims by the Executive for benefits under this Agreement shall be directed in writing to and determined by the Committee, which shall give full consideration to the evidentiary standards
set forth in this Agreement. Any denial by the Committee of a claim for benefits under this Agreement shall be delivered to the Executive in writing and shall set forth the specific reasons for the denial and the specific provisions of this
Agreement relied upon. The Committee shall afford a reasonable opportunity to the Executive for a review of the decision denying a claim and shall further allow the Executive to appeal to the Committee a decision of the Committee within sixty
(60) days after notification by the Committee that the Executive’s claim has been denied. Any further dispute or controversy arising under or in connection with this Agreement shall be settled exclusively by arbitration in Allegheny
County, Pennsylvania in accordance with the rules of the American Arbitration Association then in effect; provided, however, that the evidentiary standards set forth in this Agreement shall apply. Judgment may be entered on the
arbitrator’s award in any court having jurisdiction. Notwithstanding any provision of this Agreement to the contrary, the Executive shall be entitled to seek specific performance of the Executive’s right to be paid until the Date of
Termination during the pendency of any dispute or controversy arising under or in connection with this Agreement. 
 16. Definitions. For purposes of
this Agreement, the following terms shall have the meanings indicated below: 
 (A) “Accounting Firm” shall have the meaning stated
in Section 6.2(B) hereof. 
 (B) “Beneficial Owner” shall have the meaning set forth in Rule 13d-3 under the Exchange Act.

 (C) “Board” shall mean the Board of Directors of the Company. 
 (D) “Cause” for termination by the Company of the Executive’s employment shall mean (i) the deliberate and continued failure by the
Executive to devote substantially all the Executive’s business time and best efforts to the performance of the Executive’s duties after a demand for substantial performance is delivered to the Executive by the Board which specifically
identifies the manner in which the Executive has not substantially performed such duties; (ii) the deliberate engaging by the Executive in gross misconduct which is demonstrably and materially injurious to the Company, monetarily or otherwise,
including but not limited to fraud or embezzlement by the Executive; or (iii) the Executive’s 

  

 - 12 - 

 
conviction (or entering into a plea bargain admitting guilt) of any felony. For the purposes of this Agreement, no act, or failure to act, on the part of the
Executive shall be considered “deliberate” unless done, or omitted to be done, by the Executive not in good faith and without reasonable belief that such action or omission was in the best interests of the Company. In the event of a
dispute concerning the application of this provision, no claim by the Company that Cause exists shall be given effect unless the Company establishes to the Committee by clear and convincing evidence that Cause exists.

“Chapter 11 case”), the Company is no longer a wholly-owned subsidiary of AHI and the event occurs after such emergence. For purposes of the proceeding clause (ii), the terms “Potential Change in Control”, “Beneficial
Owner”, “Board”, “Committee”, and “Stock Plan” used in this Agreement shall be construed with respect to AHI. Notwithstanding anything to the contrary herein, the Company’s emergence from the Chapter 11 case

of securities of the Company (not including in the securities beneficially owned by such Person any securities acquired directly from the Company or its affiliates) representing 20% or more of either the then outstanding shares of common stock of
the Company or the combined voting power of the Company’s then outstanding securities, excluding any Person who becomes such a Beneficial Owner in connection with a transaction described in clause (i) of paragraph (III) below (During the
period prior to the entry of an order confirming a plan of reorganization in the Company’s Chapter 11 Case, an event described under this Section 16 (E) (I) will not constitute a Change in Control); or 
 (II) the following individuals cease for any reason to constitute a majority of the number of directors then serving: individuals who, on the date hereof,
constitute the Board and any new director (other than a director whose initial assumption of office is in connection with an actual or threatened election contest, including but not limited to a consent solicitation, relating to the election of
directors of the Company) whose appointment or election by the Board or nomination for election by the Company’s shareholders was approved by a vote of at least two-thirds (2/3) of the directors then still in office who either were
directors on the date hereof or whose appointment, election or nomination for election was previously so approved; or 
 (III) there is
consummated a merger or consolidation of the Company (including a triangular merger to which the Company is a party) with any

other corporation other than (i) a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to
such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or any parent thereof) at least 66 2/3% of the combined voting power of the voting securities
of the Company or such surviving entity or any parent thereof outstanding immediately after such merger or consolidation, or (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in
which no Person is or becomes the Beneficial Owner, directly or indirectly, of securities of the Company (not including in the securities Beneficially Owned by such Person any securities acquired directly from the Company or its subsidiaries)
representing 20% or more of either the then outstanding shares of common stock of the Company or the combined voting power of the Company’s then outstanding securities; or 
 (IV) the shareholders of the Company approve a plan of complete liquidation or dissolution of the Company or there is consummated an agreement for the
sale or disposition by the Company of all or substantially all of the Company’s assets, other than a sale or disposition by the Company of all or substantially all of the Company’s assets to an entity, at least 75% of the combined voting
power of the voting securities of which are owned by shareholders of the Company in substantially the same proportions as their ownership of the Company immediately prior to such sale. Notwithstanding the foregoing, no “Change in Control”
shall be deemed to have occurred if there is consummated any transaction or series of integrated transactions immediately following which the record holders of the common stock of the Company immediately prior to such transaction or series of
transactions continue to have substantially the same proportionate ownership in an entity which owns all or substantially all of the assets of the Company immediately following such transaction or series of transactions.

arrangement (embodied in an ongoing substitute or alternative plan) has been made with respect to such plan, or the failure by the Company to continue the Executive’s participation therein (or in such substitute or alternative plan) on a basis
not materially less favorable, both in terms of the amount or timing of payment of benefits provided and the level of the Executive’s participation relative to other participants, as existed immediately prior to the Change in Control;

under any of the Company’s pension, savings, life insurance, medical, health and accident, or disability plans in which the Executive was participating immediately prior to the Change in Control, the taking of any action by the Company which
would directly or indirectly materially reduce any of such benefits or deprive the Executive of any material fringe benefit enjoyed by the Executive at the time of the Change in Control, or the failure by the Company to provide the Executive with
the number of paid vacation days to which the Executive is entitled on the basis of years of service with the Company in accordance with the Company’s normal vacation policy in effect at the time of the Change in Control; or

 - 16 - 

 The Executive’s right to terminate the Executive’s employment for Good Reason shall not be
affected by the Executive’s incapacity due to physical or mental illness. The Executive’s continued employment shall not constitute consent to, or a waiver of rights with respect to, any act or failure to act constituting Good Reason

 - 18 -Indemnification Agreement

 Exhibit 10.2 
 INDEMNIFICATION AGREEMENT 
 FOR 
 DIRECTORS, OFFICERS, AND EXECUTIVES OF ARMSTRONG WORLD INDUSTRIES, INC. 
 This
Agreement is made as of the 13th day of March, 2006, by and between Armstrong World Industries, Inc., a Pennsylvania
corporation (the “Corporation”) and Donald A. McCunniff (the “Indemnitee”). 
 WHEREAS, it is essential to the
Corporation that it retain and attract as directors, officers, and executive employees the most capable persons available; and 
 WHEREAS,
Indemnitee is an officer, executive employee and/or a member of the Board of Directors of the Corporation and, at the Corporation’s request, may also become an executive officer of one or more of the Corporation’s executive committees and
affiliated companies, and in those capacities is performing a valuable service for the Corporation, and 
 WHEREAS, the Corporation maintains
one or more policies of Directors and Officers Liability Insurance (“D & O Insurance”) covering certain liabilities which may be incurred by directors, officers, executive employees, and others in their performance of services for
or on behalf of the Corporation; and 
 WHEREAS, there is concern over the continued adequacy and reliability of available D & O
Insurance protection; and 
 WHEREAS, for those directors and officers covered by the Corporation’s bylaw (the “Bylaw”) that
provides for indemnification by the Corporation, the Corporation wishes to expand upon and spell out the terms and procedures by which the provisions of the Bylaw are to be implemented; and 
 WHEREAS, in recognition of Indemnitee’s need for substantial protection against personal liability in order to induce and retain Indemnitee’s
service to the Corporation, the increasing difficulty in obtaining satisfactory D & O Insurance coverage, and in part to provide Indemnitee with specific contractual assurance that the protection promised by the Bylaw will be available to
Indemnitee (regardless of, among other things, any amendment to or revocation of the bylaws or any change in the composition of the Corporation’s Board of Directors or acquisition transaction relating to the Corporation), the Corporation wishes
to provide in this Agreement for the indemnification of and the advancing of expenses to Indemnitee to the fullest extent (whether partial or complete) permitted by law and as set forth in this Agreement, and, to the extent insurance is maintained,
for the continued coverage of Indemnitee under the Corporation’s D & O Insurance policies. 

 NOW, THEREFORE, in consideration of the premises and of Indemnitee agreeing to serve or continuing to
serve in any capacity described in Section 1(a) below, and intending to be legally bound hereby, the parties hereto agree as follows: 
  

	1.	Indemnity of Indemnitee.  

 (a) The
Corporation shall hold harmless and indemnify the Indemnitee against any and all reasonable expenses, including attorneys’ fees, and any and all liability and loss, including judgments, fines, ERISA excise taxes or penalties and amounts paid or
to be paid in settlement, incurred or paid by Indemnitee, in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter “a proceeding”) and whether
or not by or in the right of the Corporation or otherwise, to which the Indemnitee is, was or at any time becomes a party, or is threatened to be made a party or is involved (as a witness or otherwise) by reason of the fact that Indemnitee is or was
a member, director, officer or executive employee of the Corporation or any affiliate or is or was serving on behalf, as a representative or at the request of the Corporation as director, officer, trustee, advisor or representative of another
corporation, partnership, joint venture, trust, foundation or other entity or enterprise, including service with respect to an employee benefit plan, whether the basis of such proceeding is alleged conduct in an official capacity or in any other
capacity while serving as a director, officer, trustee, advisor or representative, unless the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness;
provided, however, that the Corporation shall indemnify the Indemnitee in connection with a proceeding (or part thereof) initiated by the Indemnitee (other than a proceeding to enforce the Indemnitee’s rights to indemnification under this
Agreement or otherwise) prior to a Change of Control, as defined in Section 2(e), only if such proceeding (or part thereof) was authorized by the Board of Directors of the Corporation. 
 (b) Subject to the foregoing limitation concerning certain proceedings initiated by the Indemnitee prior to a Change of Control, the Corporation shall
pay the expenses (including attorneys’ fees) incurred by Indemnitee in connection with any proceeding in advance of the final disposition thereof promptly after receipt by the Corporation of a request therefor stating in reasonable detail the
expenses incurred or to be incurred. 
 (c) If a claim under paragraph (a) or (b) of this Section is not paid in full by the
Corporation within forty-five days after a written claim has been received by the Corporation, the Indemnitee may, at any time thereafter, bring suit against the Corporation to recover the unpaid amount of the claim. The burden of 

  

 2 

 
proving that indemnification or advances are not appropriate shall be on the Corporation. The Indemnitee shall also be entitled to be paid the expenses of
prosecuting such claim to the extent he or she is successful in whole or in part on the merits or otherwise in establishing his or her right to indemnification or to the advancement of expenses. The Corporation shall pay such fees and expenses in
advance of the final disposition of such action on the terms and conditions set forth in Section 1(b). 
  

	2.	Maintenance of Insurance and Funding. 

 (a)
The Corporation represents that as of the present date, it has in force and effect one or more policies of D & O Insurance (the “Insurance Policies”) with total aggregate limits in an amount deemed prudent by the Board of Directors of
the Corporation. Subject only to the provisions of Section 2(b) hereof, the Corporation agrees that, so long as Indemnitee shall continue to serve as a director, officer, or executive employee of the Corporation or in any other capacity
referred to in Section 1(a) hereof, and thereafter so long as Indemnitee shall be subject to any possible claim or threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative, by reason of the fact that
Indemnitee served in any such capacity, except as indicated in (b) below, the Corporation shall purchase and maintain in effect for the benefit of Indemnitee a binding and enforceable policy or policies of D & O Insurance providing coverage
at least comparable to that provided pursuant to the Insurance Policies. 
 (b) The Corporation shall not be required to maintain said policy
or policies of D & O Insurance in effect if, in the reasonable business judgment of the then directors of the Corporation (i) the premium cost for such insurance is substantially disproportionate to the amount of coverage, (ii) the
coverage provided by such insurance is so limited by exclusions that there is insufficient benefit from such insurance or (iii) said insurance is not otherwise reasonably available; provided however, that in the event those directors make such
a judgment, the Corporation shall purchase and maintain in force a policy or policies of D & O Insurance in the amount and with such coverage as such directors determine to be reasonably available. Notwithstanding the general provisions of this
Section 2(b), following a Change of Control, any decision not to maintain any policy or policies of D & O Insurance or to reduce the amount or coverage under any such policy or policies shall be effective only if there are
“disinterested directors” (as defined in Section 2(e) hereof) on the Board of the Corporation, and shall require the concurrence of a majority of such “disinterested directors.” 
 (c) If and to the extent the Corporation, acting under Section 2(b), does not purchase and maintain in effect the policy or policies of D & O
Insurance described in Section 2(a), the Corporation shall indemnify 

  

 3 

 
and hold harmless the Indemnitee to the full extent of the coverage which would otherwise have been provided by such policies. The rights of the Indemnitee
hereunder shall be in addition to all other rights of Indemnitee under the remaining provisions of this Agreement. 
 (d) In the event of a
Potential Change of Control or if and to the extent the Corporation is not required to maintain in effect the policy or policies of D & O Insurance described in Section 2(a) pursuant to the provisions of Section 2(b), the Corporation
shall, upon written request by Indemnitee, create a Trust for the benefit of Indemnitee and, from time to time, upon written request by Indemnitee, shall fund such Trust in an amount sufficient to pay any and all expenses, including attorneys’
fees, and any and all liability and loss, including judgments, fines, ERISA excise taxes or penalties and amounts paid, to be paid or reasonably incurred by Indemnitee or on his or her behalf for which the Indemnitee is entitled to indemnification
or with respect to which indemnification is claimed, reasonably anticipated or proposed to be paid in accordance with the terms of this Agreement or otherwise; provided that in no event shall more than $100,000 in excess of claimed, actual and
reasonably anticipated liabilities and expenses, including attorneys’ fees, be required to be deposited in any Trust created hereunder. The amounts to be deposited in the Trust pursuant to the foregoing funding obligation shall be determined by
the Reviewing Person whose determination shall be final and conclusive. The Reviewing Person shall have no liability to the Indemnitee for his or her decisions hereunder. The terms of the Trust shall provide that upon a Change of Control
(i) the Trust shall not be revoked or the principal thereof invaded, without the written consent of the Indemnitee, (ii) the Trust shall advance, within two business days of a request by the Indemnitee, any and all expenses, including
attorneys’ fees, to the Indemnitee (and the Indemnitee hereby agrees to reimburse the Trust under the circumstances under which the Indemnitee would be required to reimburse the Trustee under Section 5 of this Agreement), (iii) the
Trust shall continue to be funded by the Corporation in accordance with the funding obligation set forth above, (iv) the Trustee shall promptly pay to the Indemnitee, within two business days of a request by the Indemnitee, all amounts for
which the Indemnitee shall be entitled to indemnification pursuant to this Agreement or otherwise, and (v) all unexpended funds in such Trust shall revert to the Corporation upon a final determination by the Reviewing Party or a court of
competent jurisdiction, as the case may be, that the Indemnitee has been fully indemnified under the terms of this Agreement. The Trustee shall be a bank, trust company, law firm or other individual or entity chosen by the Indemnitee and reasonably
acceptable to the Corporation. 
  

 4 

 (e) For the purposes of this Agreement: 
 (i) a “Change of Control” shall occur if and when (A) any person acquires “beneficial ownership” of more than 28%
of the then outstanding “voting stock” of the Corporation and within five years thereafter, “disinterested directors” no longer constitute at least a majority of its entire Board of Directors or (B) there shall occur a
“business combination” with an “interested shareholder” not approved by a majority of the “disinterested directors.” Any person’s acquisition of voting stock in connection with the Corporation’s emergence from
Chapter 11 shall not constitute a Change of Control for purposes of this Agreement. 
 (ii) a “Potential Change of
Control” shall occur if (A) the Corporation enters into an agreement or arrangement, the consummation of which would result in the occurrence of a Change of Control; (B) any person publicly announces a tender offer or comparable
action which if consummated would constitute a Change of Control; (C) any person (other than a trustee or other fiduciary holding securities under an employee benefit plan of the Corporation acting in such capacity or a corporation owned,
directly or indirectly, by the shareholders of the Corporation in substantially the same proportions as their ownership of stock of the Corporation), who is or becomes the beneficial owner, directly or indirectly, of securities of the Parent
representing 10% or more of the combined voting stock increases his or her beneficial ownership of such securities by 5% or more; or (D) the Board of the Corporation adopts a resolution to the effect that, for the purposes of this Agreement, a
Potential Change of Control has occurred. 
 (iii) a “Reviewing Person” means any appropriate person or body
consisting of a member or members of the Corporation’s Board of Directors or any other person or body appointed by that Board which, following a Change of Control, shall require the concurrence of a majority of the “disinterested
directors” or shall be independent legal counsel approved and accepted by the Indemnitee who is not a party to the particular claim for which Indemnitee is seeking indemnification. 
 For purposes of this subsection, the terms “person,” “beneficial owner,” “voting stock,” “disinterested
director,” “business combination,” and “interested shareholder” shall have the meaning given to them in Article 7 of the Corporation’s Articles of Incorporation as most recently amended prior to this date. 

 

 5 

	3.	Continuation of Indemnity. 

 All agreements
and obligations of the Corporation contained in this Agreement shall continue during the period the Indemnitee is a director, officer or executive employee of the Corporation or serves in any other capacity referred to in Section 1(a) hereof,
and shall continue thereafter so long as the Indemnitee shall be subject to any possible claim or threatened, pending or completed action, suit or proceeding, whether civil, criminal or investigative, by reason of the fact that the Indemnitee served
in any such capacity. 
  

	4.	Notification and Defense of Claim. 

 As soon
as practicable after receipt by the Indemnitee of actual knowledge of any action, suit or proceeding, the Indemnitee will notify the Corporation thereof, if a claim in respect thereof may be or is being made by the Indemnitee against the Corporation
under this Agreement. The Indemnitee has no duty to notify the Corporation as to any matter that the Corporation has separate notice of. With respect to any such action, suit or proceeding: 
 (a) The Corporation will be entitled to participate therein at its own expense; and 
 (b) Except as otherwise provided below, the Corporation may assume the defense thereof, with counsel reasonably satisfactory to the Indemnitee. After the
Corporation notifies the Indemnitee of its election to so assume the defense, the Corporation will not be liable to the Indemnitee under this Agreement for any legal or other expenses subsequently incurred by the Indemnitee in connection with the
defense, other than reasonable costs of investigation, including an investigation in connection with determining whether there exists a conflict of interest of the type described in (ii) of this paragraph, or as otherwise provided in this
paragraph. The Indemnitee shall have the right to employ his or her counsel in such action, suit or proceeding, but the fees and expenses of such counsel incurred after the Corporation notifies the Indemnitee of its assumption of the defense shall
be at the expense of the Indemnitee unless (i) the Corporation authorizes the Indemnitee’s engagement of such counsel which, following a “Change of Control,” shall be effective if authorized by either the Corporation’s
General Counsel, its Board of Directors, or a majority of the “disinterested directors” (which terms are defined in Section 2(e)), although constituting less than a quorum or majority of a quorum of the directors then in office;
(ii) the Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Corporation and the Indemnitee in the conduct of the defense or (iii) the Corporation shall not have engaged counsel to assume the
defense of such action, in each of which cases the fees and expenses of counsel shall be at the expense of 

  

 6 

 
the Corporation. The Corporation shall not be entitled to assume the defense of any action, suit or proceeding brought by or on behalf of the Corporation or
as to which the Indemnitee shall have made the conclusion described in (ii) of this paragraph. 
 (c) The Corporation shall not be
obligated to indemnify the Indemnitee under this Agreement for any amounts paid in settlement of any action or claim effected without its written consent. The Corporation shall not settle any action or claim in any manner which would impose any
penalty limitation on the Indemnitee without the Indemnitee’s written consent. Neither the Corporation nor the Indemnitee shall unreasonably withhold their consent to any proposed settlement. 
  

	5.	Undertaking to Repay Expenses. 

 In the event
it shall be finally determined that the Indemnitee is not entitled under this Agreement or otherwise to be indemnified for liabilities and/or expenses paid by the Corporation, the Indemnitee shall repay to the Corporation such amount of the
liability and/or expenses, or the appropriate portion thereof, so paid or advanced to which the Indemnitee was not entitled. 
  

	6.	Notice. 

 Any notice to the Corporation shall
be directed to Armstrong World Industries, Inc., 2500 Columbia Avenue, Lancaster, Pennsylvania 17603, Attention: Secretary (or such other address as the Corporation shall designate in writing to the Indemnitee). 
  

	7.	Enforcement. 

 In the event the Indemnitee is
required to bring any action to enforce rights or to collect monies due under this Agreement, the Corporation shall pay to the Indemnitee the fees and expenses incurred by the Indemnitee in bringing and pursuing such action to the extent the
Indemnitee is successful, in whole or in part, on the merits or otherwise, in such action. The Corporation shall pay such fees and expenses in advance of the final disposition of such action on the terms and conditions set forth herein. 

 

	8.	Severability. 

 If any provision or
provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: 
 (a) the validity, legality
and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid,
illegal or unenforceable) shall not in any way be affected or impaired thereby; and 
  

 7 

 (b) to the fullest extent possible, the provisions of this Agreement (including, without limitation, each
portion of any Section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the
provision held invalid, illegal or unenforceable. 
  

	9.	Indemnification Under this Agreement Not Exclusive. 

 The indemnification provided by this Agreement shall not be deemed exclusive of any other rights to which the Indemnitee may be entitled under law, the Articles of Incorporation of the Corporation or its bylaws, any other agreement, any
vote of stockholders or directors, or otherwise. 
  

	10.	Miscellaneous. 

 (a) This Agreement shall be
interpreted and enforced in accordance with the laws of the Commonwealth of Pennsylvania. 
 (b) This Agreement shall be binding upon the
Indemnitee and the Corporation, and their respective successors and assigns, and shall inure to the benefit of the Indemnitee, his or her heirs, executors, personal representatives and assigns and to the benefit of the Corporation and its successors
and assigns. If the Corporation shall merge or consolidate with another corporation or shall sell, lease, transfer or otherwise dispose of all or substantially all of its assets to one or more persons or groups (in one transaction or series of
transactions), (i) the Corporation shall cause the successor in the merger or consolidation or one or more transferee(s) of assets that constitute at least a majority of the assets and earning power transferred pursuant to the transfer of the
assets, by agreement in form and substance satisfactory to the Indemnitee, to expressly assume all of the Corporation’s obligations under and agree to perform this Agreement, and (ii) the term “Corporation” whenever used in this
Agreement shall mean and include any such successor or transferee. 
 (c) No amendment, modification, termination or cancellation of this
Agreement shall be effective unless in writing signed by both of the parties hereto. 
 IN WITNESS WHEREOF, the parties have executed this Agreement
as of the date written above.
