 ARTICLE VII 

INDEMNIFICATION 
 7.1
Indemnification by AWI. Except as otherwise specifically set forth in this Agreement, to the fullest extent permitted by Law, AWI shall, and shall cause the other members of the AWI Group (including any sublicensee) to indemnify, defend and
hold harmless AFI, each member of the AFI Group and each of their respective past, present and future directors, officers, employees and agents, in each case, in their respective capacities as such, and each of the heirs, executors, successors and
assigns of any of the foregoing (collectively, the “AFI Indemnitees”), from and against any and all Liabilities of the AFI Indemnitees relating to, arising out of or resulting from, directly or indirectly, any of the following items
(without duplication): 
 (a) any Liabilities to the extent such Liabilities arise out of any Third-Party Claim relating to, arising out of
or resulting from, directly or indirectly, use of the Marks by, under or through AWI or its Affiliates or sublicensees (including with respect to the manufacture, marketing, offering, use, issuance, sale or performance of any Licensee Products and
Services); or 
 (b) any breach by AWI or any other member of the AWI Group (including any sublicensee) of this Agreement. 

7.2 Indemnification by AFI. Except as otherwise specifically set forth in this Agreement, to the fullest extent permitted by Law, AFI
shall, and shall cause the other members of the AFI Group (other than AWI and its sublicensees) to, indemnify, defend and hold harmless AWI, each member of the AWI Group and each of their respective past, present and future directors, officers,
employees or agents, in each case in their respective capacities as such, and each of the heirs, executors, successors and assigns of any of the foregoing (collectively, the “AWI Indemnitees”), from and against any and all
Liabilities of the AWI Indemnitees relating to, arising out of or resulting from, directly or indirectly, any of the following items (without duplication): 

(a) any Liabilities to the extent such Liabilities arise out of any Third-Party Claim relating to, arising out of or resulting from, directly
or indirectly, use of the Marks by, under or through AFI or its Affiliates or sublicensees (other than AWI and its sublicensees) (including with respect to the manufacture, marketing, offering, use, issuance, sale or performance of any Licensor
Products and Services); or 
 (b) any breach by AFI or any other member of the AFI Group (other than AWI and its sublicensees) of this
Agreement. 
 7.3 Indemnification Obligations Net of Insurance Proceeds and Other Amounts. 

(a) The Parties intend that the indemnification, contribution or reimbursement with respect to any Liability pursuant to this Article
VII shall be net of Insurance Proceeds and other amounts actually recovered (net of any out-of-pocket costs or expenses incurred in the collection thereof, including increased premiums) from any Person by or on behalf of the

  
 9 

 
Indemnitee in respect of any indemnifiable Liability. Accordingly, the amount which either Party (an “Indemnifying Party”) is required to pay to any Person entitled to
indemnification, contribution or reimbursement hereunder (an “Indemnitee”) will be reduced by any Insurance Proceeds and other amounts actually recovered (net of any out-of-pocket costs or expenses incurred in the collection
thereof, including increased premiums) from any Person by or on behalf of the Indemnitee in respect of the related Liability. If an Indemnitee receives an indemnification, contribution or reimbursement payment (an “Indemnity
Payment”) required by this Agreement from an Indemnifying Party in respect of any Liability and subsequently receives Insurance Proceeds or any other amounts in respect of the related Liability, then the Indemnitee will pay to the
Indemnifying Party an amount equal to the excess of the Indemnity Payment received over the amount of the Indemnity Payment that would have been due if the Insurance Proceeds or such other amounts (net of any out-of-pocket costs or expenses incurred
in the collection thereof, including increased premiums) had been received, realized or recovered before the Indemnity Payment was made. 

(b) The Parties agree that an insurer that would otherwise be obligated to pay any claim shall not be relieved of the responsibility with
respect thereto or, solely by virtue of any provision contained in this Agreement, have any subrogation rights with respect thereto, it being understood that no insurer or any other Third Party shall be entitled to a “windfall” (i.e., a
benefit they would not be entitled to receive in the absence of the indemnification provisions) by virtue of the indemnification, contribution and reimbursement provisions hereof. Each Party shall, and shall cause the members of such Party’s
Group to, use commercially reasonable efforts (taking into account the probability of success on the merits and the cost of expending such efforts, including attorneys’ fees and expenses) to collect or recover any Insurance Proceeds that may be
collectible or recoverable respecting the Liabilities for which indemnification, contribution or reimbursement may be available under this Article VII. Notwithstanding the foregoing, an Indemnifying Party may not delay making any
indemnification payment required under the terms of this Agreement, or otherwise satisfying any indemnification obligation, pending the outcome of any Action to collect or recover Insurance Proceeds, and an Indemnitee need not attempt to collect any
Insurance Proceeds prior to making a claim for indemnification, contribution or reimbursement, or receiving any Indemnity Payment otherwise owed to it under this Agreement. 

7.4 Procedures for Indemnification of Third-Party Claims. 

(a) Notice of Claims. If, at or following the Effective Date, an Indemnitee shall receive notice or otherwise learn of the assertion by
a Person (including any Governmental Authority) that is not a member of the AWI Group or the AFI Group (or their respective sublicensees) of any claim or of the commencement by any such Person of any Action (collectively, a “Third-Party
Claim”) with respect to which an Indemnifying Party may be obligated to provide indemnification to such Indemnitee pursuant to Section 7.1 or 7.2, or any other Section of this Agreement, such Indemnitee shall give such
Indemnifying Party written notice thereof as soon as practicable, but in any event within fourteen (14) days (or sooner if the nature of the Third-Party Claim so requires) after becoming aware of such Third-Party Claim. Any such notice shall
describe the Third-Party Claim in reasonable detail, including the facts and circumstances giving rise to such claim for indemnification, and include copies of all notices and documents (including court papers) received by the Indemnitee relating to
the Third-Party Claim. 

  
 10 

 
Notwithstanding the foregoing, the failure of an Indemnitee to provide notice in accordance with this Section 7.4(a) shall not relieve an Indemnifying Party of its indemnification
obligations under this Agreement, except to the extent to which the Indemnifying Party is actually prejudiced in some material respect by the Indemnitee’s failure to provide notice in accordance with this Section 7.4(a). 

(b) Control of Defense. An Indemnifying Party may elect to defend (and seek to settle or compromise), at its own expense and with its
own counsel, any Third-Party Claim; provided that, prior to the Indemnifying Party assuming and controlling defense of such Third-Party Claim, it shall first confirm to the Indemnitee in writing that, assuming the facts presented to the
Indemnifying Party by the Indemnitee being true, the Indemnifying Party shall indemnify the Indemnitee for any such Liabilities to the extent resulting from, or arising out of, such Third-Party Claim. Notwithstanding the foregoing, if the
Indemnifying Party assumes such defense and, in the course of defending such Third-Party Claim, (i) the Indemnifying Party discovers that the facts presented at the time the Indemnifying Party acknowledged its indemnification obligation in
respect of such Third-Party Claim were not true in all material respects and (ii) such untruth provides a reasonable basis for asserting that the Indemnifying Party does not have an indemnification obligation in respect of such Third-Party
Claim, then (A) the Indemnifying Party shall not be bound by such acknowledgment, (B) the Indemnifying Party shall promptly thereafter provide the Indemnitee written notice of its assertion that it does not have an indemnification
obligation in respect of such Third-Party Claim and (C) the Indemnitee shall have the right to assume the defense of such Third-Party Claim. Within thirty (30) days after the receipt of a notice from an Indemnitee in accordance with
Section 7.4(a) (or sooner, if the nature of the Third-Party Claim so requires), the Indemnifying Party shall provide written notice to the Indemnitee indicating whether the Indemnifying Party shall assume responsibility for defending the
Third-Party Claim. If an Indemnifying Party elects not to assume responsibility for defending any Third-Party Claim or fails to notify an Indemnitee of its election within thirty (30) days after receipt of the notice from an Indemnitee as
provided in Section 7.4(a), then the Indemnitee that is the subject of such Third-Party Claim shall be entitled to continue to conduct and control the defense of such Third-Party Claim. 

(c) Allocation of Defense Costs. If an Indemnifying Party has elected to assume the defense of a Third-Party Claim, then such
Indemnifying Party shall be solely liable for all fees and expenses incurred by it in connection with the defense of such Third-Party Claim and shall not be entitled to seek any indemnification, contribution or reimbursement from the Indemnitee for
any such fees or expenses incurred by the Indemnifying Party during the course of the defense of such Third-Party Claim by such Indemnifying Party, regardless of any subsequent decision by the Indemnifying Party to reject or otherwise abandon its
assumption of such defense. If an Indemnifying Party elects not to assume responsibility for defending any Third-Party Claim or fails to notify an Indemnitee of its election within thirty (30) days after receipt of a notice from an Indemnitee
as provided in Section 7.4(a), and the Indemnitee conducts and controls the defense of such Third-Party Claim and the Indemnifying Party has an indemnification obligation with respect to such Third-Party Claim, then the Indemnifying
Party shall be liable for all reasonable fees and expenses incurred by the Indemnitee in connection with the defense of such Third-Party Claim. 

  
 11 

 (d) Right to Monitor and Participate. An Indemnitee that does not conduct and control the
defense of any Third-Party Claim, or an Indemnifying Party that has failed to elect to defend any Third-Party Claim as contemplated hereby, nevertheless shall have the right to employ separate counsel (including local counsel as necessary) of its
own choosing to monitor and participate in (but not control) the defense of any Third-Party Claim for which it is a potential Indemnitee or Indemnifying Party, but the fees and expenses of such counsel shall be at the expense of such Indemnitee or
Indemnifying Party, as the case may be, and the provisions of Section 7.4(c) shall not apply to such fees and expenses. Notwithstanding the foregoing, such Party shall cooperate with the Party entitled to conduct and control the defense
of such Third-Party Claim in such defense and make available to the controlling Party, at the non-controlling Party’s expense, all witnesses, information and materials in such Party’s possession or under such Party’s control relating
thereto as are reasonably required by the controlling Party. In addition to the foregoing, if any Indemnitee shall in good faith determine that such Indemnitee and the Indemnifying Party have actual or potential differing defenses or conflicts of
interest between them that make joint representation inappropriate, then the Indemnitee shall have the right to employ separate counsel (including local counsel as necessary) and to participate in (but not control) the defense, compromise, or
settlement thereof, and the Indemnifying Party shall bear the reasonable fees and expenses of such counsel for all Indemnitees. 
 (e) No
Settlement. Neither Party may settle or compromise any Third-Party Claim for which either Party is seeking to be indemnified hereunder without the prior written consent of the other Party, which consent may not be unreasonably withheld, unless
such settlement or compromise is solely for monetary damages, does not involve any finding or determination of wrongdoing or violation of Law by the other Party and provides for a full, unconditional and irrevocable release of the other Party from
all Liability in connection with the Third-Party Claim. 
 (f) Tax Matters Agreement Governs. The above provisions of this
Section 7.4 do not apply to Taxes (as defined in the Separation Agreement) (Taxes being governed by the Tax Matters Agreement). In the case of any conflict between this Agreement and the Tax Matters Agreement in relation to any matters
addressed by the Tax Matters Agreement, the Tax Matters Agreement shall prevail.

has a material adverse impact on the business or reputation, taken as a whole, of the non-breaching Party, and the breaching Party fails to cure such breach or, if such breach is not reasonably curable during such time period, fails to implement
steps reasonably intended to cure or remedy such breach within sixty (60) days’ written notice from the non-breaching Party, this Agreement may be terminated upon written notice by the non-breaching Party. 

(iii) Licensee shall have the right at any time to terminate this Agreement upon written notice to Licensor. 

8.2 Effect of Termination. 

(a) Upon expiration or earlier termination of this Agreement, the Licensee shall and shall cause each of its sublicensees to, within one
(1) year of termination or by or upon the date of expiration, cease any and all use of the Marks and any mark confusingly similar thereto. 

8.3 Rights and Remedies. The rights and remedies of Licensor set forth in this Article VIII are in addition to all other rights
and remedies available at law or equity. 
 ARTICLE IX 

CONFIDENTIALITY 
 9.1
Confidentiality. Each of Licensor and Licensee, on behalf of itself and each member of its respective Group, agrees to hold, and to cause its respective Representatives to hold, in strict confidence, with at least the same degree of care that
applies to AWI’s confidential and proprietary information pursuant to policies in effect as of the Effective Date, all confidential and proprietary information concerning the other Party or any member of the other Party’s Group or their
respective businesses that may be in its possession as of the Effective Date or is furnished by any such other Party or any member of such Party’s Group or their respective Representatives at any time pursuant to this Agreement, and shall not
use any such confidential and proprietary information other than for such purposes as shall be expressly permitted hereunder, except, in each case, to the extent that such confidential and proprietary information has been (i) in the public
domain or generally available to the public, other than as a result of a disclosure by such Party or any member of such Party’s Group or any of their respective Representatives in violation of this Agreement, (ii) later lawfully acquired
from other sources by such Party (or any member of such Party’s Group) which sources are not themselves bound by a confidentiality obligation or other contractual, legal or fiduciary obligation of confidentiality with respect to such
confidential and proprietary information, or (iii) independently developed or generated without reference to or use of any proprietary or confidential information of the other Party or any member of such Party’s Group. 

9.2 Protective Arrangements. In the event that a Party or any member of its Group either determines on the advice of its counsel that
it is required to disclose any information pursuant to applicable Law or receives any request or demand under lawful process or from any 

  
 13 

 
Governmental Authority to disclose or provide information of the other Party (or any member of the other Party’s Group) that is subject to the confidentiality provisions hereof, such Party
shall notify the other Party (to the extent legally permitted) as promptly as practicable under the circumstances prior to disclosing or providing such information and shall cooperate, at the expense of the other Party, in seeking any appropriate
protective order requested by the other Party. In the event that such other Party fails to receive such appropriate protective order in a timely manner and the Party receiving the request or demand reasonably determines that its failure to disclose
or provide such information shall actually prejudice the Party receiving the request or demand, then the Party that received such request or demand may thereafter disclose or provide information to the extent required by such Law (as so advised by
its counsel) or by lawful process or such Governmental Authority, and the disclosing Party shall promptly provide the other Party with a copy of the information so disclosed, in the same form and format so disclosed, together with a list of all
Persons to whom such information was disclosed, in each case to the extent legally permitted. 
 ARTICLE X 

MISCELLANEOUS 
 10.1
Counterparts; Entire Agreement; Corporate Power. 
 (a) This Agreement may be executed in one or more counterparts, all of which
shall be considered one and the same agreement, and shall become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Party. 

(b) This Agreement and the Exhibits, Schedules and appendices hereto, and the Separation Agreement, contain the entire agreement between the
Parties with respect to the subject matter hereof, supersede all previous agreements, negotiations, discussions, writings, understandings, commitments and conversations with respect to such subject matter, and there are no agreements or
understandings between the Parties other than those set forth or referred to herein or therein. In the case of any conflict between this Agreement and the Separation Agreement in relation to any matters addressed by this Agreement, the Separation
Agreement shall prevail. 
 (c) AWI represents on behalf of itself and each other member of the AWI Group, and AFI represents on behalf of
itself and each other member of the AFI Group, as follows: 
 (i) each such Person has the requisite corporate or other power
and authority and has taken all corporate or other action necessary in order to execute, deliver and perform this Agreement to which it is a party and to consummate the transactions contemplated hereby and thereby; and 

(ii) this Agreement to which it is a party has been duly executed and delivered by it and constitutes a valid and binding

 (d) Each Party acknowledges that this Agreement may be executed by facsimile, stamp or mechanical
signature, and that delivery of an executed counterpart of a signature page to this Agreement (whether executed by manual, stamp or mechanical signature) by facsimile or by email in portable document format (PDF) shall be effective as delivery of
such executed counterpart of this Agreement. Each Party expressly adopts and confirms each such facsimile, stamp or mechanical signature (regardless of whether delivered in person, by mail, by courier, by facsimile or by email in portable document
format (PDF)) made in its respective name as if it were a manual signature delivered in person, agrees that it will not assert that any such signature or delivery is not adequate to bind such Party to the same extent as if it were signed manually
and delivered in person and agrees that, at the reasonable request of the other Party at any time, it will as promptly as reasonably practicable cause this Agreement to be manually executed (any such execution to be as of the date of the initial
date thereof) and delivered in person, by mail or by courier. 
 10.2 Governing Law. This Agreement (and any claims or disputes
arising out of or related hereto or to the transactions contemplated hereby or to the inducement of any party to enter herein , whether for breach of contract, tortious conduct or otherwise and whether predicated on common law, statute or otherwise)
shall be governed by and construed and interpreted in accordance with the Laws of the State of Delaware irrespective of the choice of laws principles of the State of Delaware including all matters of validity, construction, effect, enforceability,
performance and remedies. 
 10.3 Dispute Resolution. 

(a) Good Faith Negotiation. Any dispute, controversy or claim arising out of or relating to this Agreement (a
“Dispute”), shall initially be referred to the Transition Committee (as defined in the Separation Agreement, and for so long as such Transition Committee exists) for resolution. If the Transition Committee (as defined in the
Separation Agreement) is unable to resolve such Dispute within thirty (30) days (or if such Transition Committee no longer exists), then either Party may provide written notice thereof to the other Party (the “Initial Notice”),
and the Parties shall thereafter attempt in good faith to negotiate a resolution of the Dispute. The negotiations shall be conducted by executives who hold, at a minimum, the title of vice president and who have authority to settle the Dispute. All
such negotiations shall be confidential and shall be treated as compromise and settlement negotiations for purposes of applicable rules of evidence. 

(b) In the event that a Dispute has not been resolved within sixty (60) days after receipt by a Party of an Initial Notice, or within
such longer period as the Parties may agree to in writing, then each Party hereby agrees and consents to be subject to the jurisdiction of the Court of Chancery of the State of Delaware in and for New Castle County, or if the Court of Chancery lacks
jurisdiction over such dispute, in any state or federal court having jurisdiction over the matter situated in New Castle County, Delaware, to resolve any such unresolved Dispute in any suit, action or proceeding seeking to enforce any provision of,
or based on any other matter arising out of or in connection with, this Agreement or the transactions contemplated hereby. Each Party hereby irrevocably consents to the service of any and all process in any such suit, action or proceeding by the
delivery of such process to such Party at the address and in the manner provided in Section 10.7 hereof. Each of the Parties hereto 

  
 15 

 
irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in the Court of
Chancery of the State of Delaware in and for New Castle County, or if the Court of Chancery lacks jurisdiction over such dispute, in any state or federal court having jurisdiction over the matter situated in New Castle County, Delaware, and hereby
further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court has been brought in an inconvenient forum. 

(c) EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND
DIFFICULT ISSUES, AND THEREFORE EACH PARTY HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT, OR THE
BREACH, TERMINATION OR VALIDITY OF THIS AGREEMENT, OR THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR
OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH SUCH PARTY MAKES THIS WAIVER
VOLUNTARILY AND (iv) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10.3(c). 

(d) Notwithstanding the foregoing provisions of this Section 10.3, a Party may seek preliminary provisional or injunctive judicial
relief with respect to a Dispute without first complying with the procedures set forth in Section 10.3(a) if such action is reasonably necessary to avoid irreparable damage. 

(e) Unless otherwise agreed in writing, the Parties shall, and shall cause their respective members of their Group to, continue to honor all
commitments under this Agreement to the extent required by this Agreement during the course of dispute resolution pursuant to the provisions of this Section 10.3, unless such commitments are the specific subject of the Dispute at issue.

 10.4 Assignability. This Agreement shall be binding upon and inure to the benefit of the Parties and their respective successors
and permitted assigns; provided, however, that neither Party may assign its rights or delegate its obligations under this Agreement without the express prior written consent of the other Party hereto. Notwithstanding the foregoing, no
such consent shall be required for the assignment of a Party’s rights and obligations under this Agreement in whole (i.e., the assignment of a Party’s rights and obligations under this Agreement all at the same time) in connection with a
change of control of a Party so long as the resulting, surviving or transferee Person assumes all the obligations of the relevant party thereto by operation of Law or pursuant to an agreement in form and substance reasonably satisfactory to the
other Party. Nothing herein is intended to, or shall be construed to, prohibit either Party or any member of its Group from being party to or undertaking a change of control. 

  
 16 

 10.5 Third-Party Beneficiaries. Except for the indemnification rights under this Agreement
of any AWI Indemnitee or AFI Indemnitee in their respective capacities as such, and as set forth in Article VII (a) the provisions of this Agreement are solely for the benefit of the Parties and are not intended to confer upon any Person
except the Parties any rights or remedies hereunder, and (b) there are no third-party beneficiaries of this Agreement and this Agreement shall not provide any third person with any remedy, claim, Liability, reimbursement, claim of action or
other right in excess of those existing without reference to this Agreement. 
 10.6 Recovery of Fees. In the event that any Action
is instituted or commenced by either Party hereto against the other Party as a result of a Dispute, the Party that substantially prevails in such Action as determined by a final, nonappealable judgment of an arbitration or court shall be entitled to
recover its reasonable attorneys’ fees and other costs incurred in such Action from the non-prevailing party. 
 10.7 Notices.

 (a) All notices, requests, claims, demands or other communications under this Agreement shall be in writing and shall be given or made
(and shall be deemed to have been duly given or made upon receipt) by delivery in person, by electronic mail (for which a confirmation email is obtained), or sent by overnight courier (providing proof of delivery) to the respective Parties at the
following addresses (or at such other address for a Party as shall be specified in a notice given in accordance with this Section 10.7):

 A Party may, by notice to the other Party, change the address to which such notices are to be given. 

10.8 Force Majeure. No Party shall be deemed in default of this Agreement for any delay or failure to fulfill any obligation (other
than a payment obligation) hereunder or thereunder so long as and to the extent to which any delay or failure in the fulfillment of such obligation is prevented, frustrated, hindered or delayed as a consequence of circumstances of Force Majeure (as
defined in the Separation Agreement). In the event of any such excused delay, the time for performance of such obligations (other than a payment obligation) shall be extended for a period equal to the time lost by reason of the delay. A Party
claiming the benefit of this provision shall, as soon as reasonably practicable after the occurrence of any such event, (a) provide written notice to the other Party of the nature and extent of any such Force Majeure condition; and (b) use
commercially reasonable efforts to remove any such causes and resume performance under this Agreement, as soon as reasonably practicable. 

  
 18 

 10.9 Headings. The article, section and paragraph headings contained in this Agreement are
for reference purposes only and shall not affect in any way the meaning or interpretation of this Agreement. 
 10.10 Waivers of
Default. Waiver by a Party of any default by the other Party of any provision of this Agreement shall not be deemed a waiver by the waiving Party of any subsequent or other default, nor shall it prejudice the rights of the other Party. No
failure or delay by a Party in exercising any right, power or privilege under this Agreement shall operate as a waiver thereof, nor shall a single or partial exercise thereof prejudice any other or further exercise thereof or the exercise of any
other right, power or privilege. 
 10.11 Specific Performance. Subject to the provisions of Section 10.3, in the event
of any actual or threatened default in, or breach of, any of the terms, conditions and provisions of this Agreement, the Party who is thereby aggrieved shall have the right to specific performance and injunctive or other equitable relief in respect
of its or their rights under this Agreement, in addition to any and all other rights and remedies at law or in equity, and all such rights and remedies shall be cumulative. The Parties agree that the remedies at law for any breach or threatened
breach, including monetary damages, are inadequate compensation for any loss and that any defense in any action for specific performance that a remedy at law would be adequate is waived. Any requirements for the securing or posting of any bond with
such remedy are waived by each of the Parties. 
 10.12 Amendments. No provisions of this Agreement shall be deemed waived, amended,
supplemented or modified by a Party, unless such waiver, amendment, supplement or modification is in writing and signed by the authorized representative of the Party against whom it is sought to enforce such waiver, amendment, supplement or
modification. 
 10.13 Interpretation. In this Agreement (a) words in the singular shall be deemed to include the plural and
vice versa and words of one gender shall be deemed to include the other genders as the context requires, (b) the terms “hereof,” “herein,” and “herewith” and words of similar import shall, unless otherwise stated,
be construed to refer to this Agreement as a whole (including all of the Schedules, Exhibits and Appendices hereto and thereto) and not to any particular provision of this Agreement, (c) Article, Section, Schedule, Exhibit and Appendix
references are to the Articles, Sections, Schedules, Exhibits and Appendices to this Agreement unless otherwise specified, (d) unless otherwise stated, all references to any agreement shall be deemed to include the exhibits, schedules and
annexes to such agreement, (e) the word “including” and words of similar import when used in this Agreement shall mean “including, without limitation,” unless otherwise specified, (f) the word “or” shall not
be exclusive, (g) unless otherwise specified in a particular case, the word “days” refers to calendar days, (h) references to “business day” shall mean any day other than a Saturday, a Sunday or a day on which banking
institutions are generally authorized or required by law to close in the United States or Lancaster, Pennsylvania, (i) references herein to this Agreement or any other agreement contemplated herein shall be deemed to refer to this Agreement or
such other agreement as of the date on which it is executed and as it may be amended, modified or supplemented thereafter, 

  
 19 

 
unless otherwise specified, and (j) unless expressly stated to the contrary in this Agreement, all references to “the date hereof,” “the date of this Agreement,”
“hereby” and “hereupon” and words of similar import shall all be references to the Effective Date. 
 10.14
Limitations of Liability. Notwithstanding anything in this Agreement to the contrary, neither AFI or any member of the AFI Group, on the one hand, nor AWI or any member of the AWI Group, on the other hand, shall be liable under this Agreement
to the other for any indirect, punitive, exemplary, remote, speculative or similar damages in excess of compensatory damages of the other arising in connection with the transactions contemplated hereby (other than any such Liability with respect to
a Third-Party Claim). 
 10.15 Performance. AWI will cause to be performed, and hereby guarantees the performance of, all actions,
agreements and obligations set forth in this Agreement to be performed by any member of the AWI Group. AFI will cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth in this Agreement to
be performed by any member of the AFI Group. Each Party (including its permitted successors and assigns) further agrees that it will (a) give timely notice of the terms, conditions and continuing obligations contained in this Agreement to all
of the other members of its Group and (b) cause all of the other members of its Group not to take any action or fail to take any such action inconsistent with such Party’s obligations under this Agreement. 

10.16 Mutual Drafting. This Agreement shall be deemed to be the joint work product of the Parties and any rule of construction that a
document shall be interpreted or construed against a drafter of such document shall not be applicable.

 AGREEMENT OF LEASE 

This AGREEMENT OF LEASE, dated as of April 1, 2016 (this “Lease”), between Armstrong World Industries, Inc., a
Pennsylvania corporation, having an address at 2500 Columbia Avenue, Building 5, Lancaster, PA 17603, party of the first part (hereinafter referred to as “Landlord”), and Armstrong Flooring, Inc., a Delaware corporation, having an
address at 2500 Columbia Avenue, Building 701, Lancaster, PA 17603, party of the second part (hereinafter referred to as “Tenant”). 

RECITALS 
 WHEREAS, pursuant to
that certain Separation and Distribution Agreement, dated as of April 1, 2016 (the “Separation and Distribution Agreement”), by and between Landlord and Tenant, Landlord desires to lease the Premises (as hereinafter defined) to
Tenant and Tenant desires to lease the Premises from Landlord upon the terms set forth in this Lease. 
 NOW, THEREFORE, for good and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties agree as follows: 
 ARTICLE 1 

PREMISES; TERM 
 1.1
Landlord hereby leases to Tenant and Tenant hereby hires from Landlord, upon and subject to the terms, covenants, provisions and conditions of this Lease, the following premises located within the Campus (as hereinafter defined) consisting of
(i) the entire Buildings (as hereinafter defined) identified on Exhibit A-1 attached hereto and made a part hereof and (ii) portions of certain Buildings identified on Exhibit A-2 and made a part hereof, in each case,
together with all Premises FF&E (as defined below) located thereon (collectively the “Premises”, and together with the land and all other improvements thereon, the “Property”). Subject to the terms of this
Lease, Tenant shall have the non-exclusive right to use, in common with Landlord and other tenants and each of their agents, guests and invitees, (i) the parking areas, exterior plazas, entrances, roadways and walkways located within the Campus
and (ii) the common areas of the Buildings described on Exhibit B attached hereto, including, without limitation, the stairways, hallways, restrooms, lobbies, patios, elevators, corridors, the meeting rooms, the fitness center, the
cafeteria, the auditorium, the loading docks and the product display areas located therein (collectively, the “Common Areas”). 

1.2 The term (the “Term”) of this Lease shall commence on the date hereof (the “Commencement Date”), and end
on the date (as the same may be extended pursuant to the terms hereof, the “Expiration Date”) which is the last day of the month preceding the month in which occurs the fifth
(5th) anniversary of the Commencement Date (the “Initial Expiration Date”) or until such Term shall sooner cease and terminate as herein provided. Tenant shall have the
option (the “6th Year Renewal Option”) to extend the Term until the sixth (6th) anniversary of the Commencement Date, which option shall be exercised upon delivery of written
notice to Landlord on or prior to the fourth (4th) anniversary of the Commencement Date. After the 6th Year Renewal Option is exercised,
the Term shall thereafter automatically renew for successive 

 
one (1) year periods (each a “Renewal Term”), unless either Landlord or Tenant delivers written notice of non-renewal to the other party on or before (i) with respect
to the first Renewal Term, twelve (12) months prior to Initial Expiration Date and (ii) with respect to any subsequent Renewal Term, eighteen (18) months prior to the expiration of the then current Renewal Term. This Lease, if and as
so extended during the Renewal Term, shall be upon the same terms and conditions as contained in this Lease, except for the Term. 
 ARTICLE
2 
 OCCUPANCY 
 2.1
Tenant agrees to use and occupy the Premises and the Licensed Space (as defined below) in a manner that is consistent with the uses made of the Premises during the twelve (12) month period immediately prior to the Commencement Date (each a
“Permitted Use” and collectively, the “Permitted Uses”) and for no other purpose whatsoever. For the avoidance of doubt, the parties agree and acknowledge that the testing of products on the existing flooring
manufacturing pilot line located within the Premises and/or the Licensed Space in connection with the research and development components of Tenant’s business shall be a Permitted Use hereunder, but in no event shall finished production
manufacturing be permitted on any portion of the Premises or the Licensed Space. 
 2.2 Tenant will not make or permit to be made any use of
the Premises, the Common Areas, the Licensed Space or any part thereof (i) which would violate any of the covenants, agreements, terms, provisions and conditions of this Lease, (ii) which would violate the provisions of any service
agreements relating to the Premises or the Licensed Space in a manner inconsistent with past practices at the Premises and Licensed Space, (iii) which is forbidden by Legal Requirements (as hereinafter defined), (iv) which may be dangerous
to life, limb, or property, (v) which may invalidate or increase the premium cost of any policy of insurance carried on the Campus or concerning its operation, (vi) which will suffer or permit the Premises, the Common Areas, the Licensed
Space or any part thereof to be used in any manner, or anything to be brought into or kept therein, which, in the reasonable judgment of Landlord, shall in any way impair or tend to impair the character, reputation or appearance of the Campus, or
(vii) which would impair or interfere, other than to a de minimis extent, or tend to impair or interfere, other than to a de minimis extent, with any of the services performed by Landlord for the Campus or which will interfere
with or disturb other tenants or users. Landlord makes no representation as to the condition of the Premises, the Common Areas or the Licensed Space except as otherwise expressly provided in this Lease, and Tenant agrees to accept the same subject
to violations whether or not of record. Tenant will not at any time use or occupy the Premises, the Common Areas or the Licensed Space or permit same to be used or occupied in violation of the certificate of occupancy for the applicable Building in
which such Premises, Common Areas or Licensed Space is located. Landlord agrees that it will not amend the current certificate of occupancy to preclude the use of the Premises for the Permitted Use applicable thereto.

Term, Tenant shall pay minimum annual rent (the “Minimum Rent”) of $5,622,900.00 per annum, together with all other sums of money as shall become due and payable by Tenant under this Lease (hereinafter called “additional
rent” or “Additional Rent”) which Tenant agrees to pay in lawful money of the United States of America which shall be legal tender in payment of all debts and dues, public and private, at the time of payment, in equal
monthly installments in advance on the first day of each month during said term, at the office of Landlord or such other place as Landlord may designate in writing, without any set off or deduction whatsoever, except that Tenant shall pay the first
monthly installment(s) on the execution hereof. The Minimum Rent and Additional Rent are collectively referred to herein as the “rent”. 

3.2 If the payment of Minimum Rent hereunder shall commence on any day other than the first day of a calendar month, then the Minimum Rent for
such calendar month shall be prorated on a per diem basis, and any excess amount paid on the execution of this Lease shall be credited to the Minimum Rent for the next calendar month. 

3.3 In the event Landlord leases all or any portion of the space identified on Exhibit C attached hereto to a third party (a
“Third Party Lease”) Tenant shall be entitled to a credit against the Minimum Rent and Additional Rent payable by Tenant hereunder by an amount equal to Tenant’s Proportionate Share of any Net Third Party Rents actually
received by Landlord, as shown on Landlord’s Operating Statement in accordance with the terms set forth in Section 5.3(c). For purposes of this Section 3.3, the term “Net Third Party Rents” shall mean
all rents, additional charges or other consideration payable under a Third Party Lease which are in excess of any brokerage commissions, tenant allowances, free rent, landlord alterations, reimbursements, reasonable attorney’s fees and other
costs and expenses incurred by Landlord in connection with such Third Party Lease amortized over the term of such Third Party Lease. In no event shall unforfeited security deposits be considered Net Third Party Rents.

Definitions as used herein: 
 (a) “Taxes” shall mean (1) the amount finally determined to be legally payable, by

nonrecurring as well as recurring, special or extraordinary as well as ordinary, foreseen and unforeseen, and each and every installment thereof, which shall be levied, assessed or imposed, or become due and payable or become liens upon, or arise in

Landlord in contesting the assessment of the Campus for real estate tax purposes or in otherwise contesting the amount of any of the real estate taxes or other governmental charges described above. If, due to a change in the method of taxation, a
new or additional tax, however designated, shall be levied against Landlord, and/or the Campus, in addition to or in substitution, in whole or in part, for any tax which would otherwise constitute “Taxes”, or in lieu of additional Taxes,

excise, excess profits, occupancy or rent, gift, estate, foreign ownership or control, payroll or stamp tax of Landlord or any superior party (except as expressly set forth in the preceding sentence), (ii) any other tax, assessment, charge or

July 1, 2015 and ending on June 30, 2016. 
 (c) “Tenant’s Proportionate Share” shall mean forty-seven
percent (47%). 
 (d) “Tax Year” shall mean each period of twelve months, commencing on the first day of July, in which
occurs any part of the Term or such other period as may hereafter be adopted as the fiscal year for real estate tax purposes in Lancaster, Pennsylvania. 

(e) “Landlord’s Tax Statement” shall mean an annual statement setting forth the amount payable by Tenant for a specified
Tax Year pursuant to this Article 5. 
 (f) “Base Operating Expenses” shall mean Operating Expenses for the 2015
calendar year. Attached hereto as Schedule 5.1 for informational purposes only is a statement setting forth the major line item expenses included in Landlord’s calculation of the Base Operating Expenses which Tenant has reviewed and
approved. 
 5.2 Payments – Tax Escalations. 

(a) If Taxes payable in any Tax Year shall exceed the Tax Base, Tenant shall pay as Additional Rent a sum (hereinafter referred to as
“Tenant’s Tax Payment”) equal to Tenant’s Proportionate Share of the amount by which the Taxes for such Tax Year exceed the Tax Base in accordance with the terms of this Section 5.2. 

(b) At any time before or after the commencement of any Tax Year, Landlord may furnish to Tenant a statement (the “Estimated Tax
Statement”) of Landlord’s reasonable estimate of Tenant’s Tax Payment for such Tax Year (the “Tenant’s Estimated Tax Payment”). The Estimated Tax Statement shall be accompanied by a copy of the tax statement
or bill for the Taxes or all components thereof. If Landlord delivers to Tenant an Estimated Tax Statement with respect to any such Tax Year, subject to the terms of Section 5.2(c), Tenant shall pay to Landlord, as Additional Rent, on
account of Tenant’s Tax Payment due hereunder for such Tax Year (or prorated portion thereof) on the date which is the later to occur of (a) thirty (30) days after receipt of Landlord’s Estimated Tax Statement, or
(b) fifteen (15) days prior to the date on which the applicable Taxes or any component thereof or any installments thereof, are due to the applicable taxing authority (such earlier date, the “Tax Due Date”). 

(c) If during any Tax Year the last-issued Estimated Tax Statement for such Tax Year is inaccurate in any respect, Landlord shall promptly
issue a revised Estimated Tax Statement. If there shall be any increase in Taxes for any Tax Year as indicated on a revised Estimated Tax Statement, Tenant shall pay to Landlord the amount shown on the revised Estimated Tax Statement on or before
the applicable Tax Due Date. Subject to the provisions of the last sentence of this Section 5.2(c), if there shall be any decrease in Taxes for any Tax Year as indicated on a revised Estimated Tax Statement, such that Tenant shall have
overpaid Tenant’s Tax Payment for the Tax Year in question, then (1) if such decrease will give rise to a credit issued by the taxing authority against future Taxes, Landlord shall credit Tenant’s

  
 5 

 
Proportionate Share of the amount of such credit, as and when received by Landlord, against the next subsequent payments of rent until such credit is fully applied, or (2) if such decrease
will give rise to a cash refund from the taxing authority to Landlord, Landlord shall refund to Tenant within thirty (30) days after receipt of such refund by Landlord, the amount of such overpayment on the revised Estimated Tax Statement for
such Tax Year. If, at the time Landlord receives any such credit or refund, Tenant is then in monetary default or material non-monetary default under this Lease, in each case, beyond the expiration of any applicable notice and/or cure period,
Landlord may offset the amount of such credit or refund payable to Tenant against amounts properly due and owing by Tenant to Landlord. 

(d) Landlord shall within sixty (60) days after the end of such Tax Year issue a statement of Taxes for such Tax Year, including a
computation of Tenant’s Tax Payment for such Tax Year (a “Tax Statement”). If Tenant shall have overpaid Taxes or any component thereof for any Tax Year, Landlord, at its option, shall, subject to the last sentence of
Section 5.2(c) hereof, either refund the amount overpaid to Tenant together with delivery of the Tax Statement or allow Tenant a credit against the next subsequent payments of Rent in the amount of Tenant’s overpayment of Taxes. If Tenant
shall have underpaid Taxes for any Tax Year, Tenant shall pay to Landlord an amount equal to the amount of such underpayment of Tenant’s Tax Payment with respect to such Tax Year within thirty (30) days after receipt of the applicable Tax
Statement. 
 (e) If the Tax Year shall be changed during the Term, any Taxes for such fiscal year, a part of which is included within a
particular Tax Year and a part of which is not so included, shall be equitably apportioned. 
 (f) If the Tax Base is reduced as a result of
a certiorari proceeding or otherwise, the Taxes as so reduced shall for all purposes be deemed to be the Taxes comprising the Tax Base and Landlord shall give notice thereof to Tenant but such reduction shall not increase any Tenant’s Tax
Payment previously paid by Tenant for any period prior to the effective date of the reduction of the Tax Base as aforesaid. 
 (g) Only
Landlord shall be eligible to institute tax reduction or other proceedings to reduce the assessed valuation of the Campus. If Landlord shall receive a refund or credit of Taxes for any Tax Year subsequent to the date of the Tax Statement for such
Tax Year but subject to the last sentence of Section 5.2(c), Landlord shall either pay to Tenant, or, at Landlord’s election, credit against the next due payments under this Section 5.2 an amount equal to Tenant’s
Proportionate Share of the refund, but such amount shall not exceed Tenant’s Tax Payment paid for such Tax Year. Provided Tenant is not then in default beyond the expiration of any applicable notice and/or cure period, any credit or refund due
Tenant at the expiration or sooner termination of the Term of this Lease shall be paid to Tenant within thirty (30) days after the expiration or sooner termination of this Lease. Nothing herein shall obligate Landlord to file any application or
institute any proceeding seeking a reduction in Taxes or assessed valuation. 
 5.3 Payments – Operating Expenses. 

(a) “Operating Expenses” shall mean the aggregate of all costs and expenses (including taxes (other than Taxes)) paid or
incurred by or on behalf of Landlord (whether 

  
 6

of accounting and shall, include, without limitation, but subject to the limitations set forth herein, the following expenses:

payroll taxes, workers’ compensation, and uniforms for such persons; 
 (ii) payments under service contracts with
independent contractors for operating (including, without limitation, providing security services), maintaining, repairing, or cleaning the Campus or any portion thereof or any fixtures or equipment therein and any payments associated with the

 (iii) except
to the extent directly billed to Tenant, all costs or charges for steam, electricity water and heating, ventilation and air-conditioning service (“HVAC”) furnished to the Campus and/or used in the operation of the Campus, including
any taxes on any such utilities; 
 (iv) all costs and expenses for repairs, replacements, capital expenditures and capital
improvements which are reasonable and necessary (determined by the Landlord in good faith and consistent with past practices) for the continued operation of the Campus, except that in the case of capital expenditures and capital improvements,
Operating Expenses shall only include the amortized cost thereof based on their useful life and a discount rate equal to the Interest Rate at the time of Landlord having incurred said expenditure; 

(v) cost of lobby decoration, and painting and decoration of non-tenant areas within the Campus; 

(vi) cost of snow removal and landscaping in and about the Campus;

of any mortgage on the Campus or any portion thereof, reasonable attorneys’ fees and disbursements, auditing and other professional fees and expenses, association dues and other ordinary and customary financial expenses incurred in connection
with the operation of the Campus;

 (ix) rental payments made for equipment used in the operation and maintenance of
the Campus; 
 (x) the cost of governmental licenses and permits, or renewals thereof, necessary for the operation of the
Campus; and 
 (xi) all other reasonable and necessary expenses paid in connection with the operation, maintenance, repair
and cleaning of the Campus which are properly chargeable against income. 
 The following costs and expenses shall be excluded from Operating

	 	(1)	Taxes; 

  

	 	(2)	debt service, amortization of principal and penalties or refinancing costs; 

  

	 	(3)	leasing costs and expenses, including brokerage commissions and similar fees;

	 	(9)	 any expenses which are not paid or incurred solely in respect of the Campus but rather in respect of the Campus and other property owned by Landlord
or its affiliates, except that notwithstanding the foregoing, with respect to any expenses attributable in part to the Campus and in part to other property owned or managed by 

  
 8 

	 	
Landlord or its affiliates (including salaries, fringe benefits and other compensation of personnel below the grade of building manager who provide services to both the Campus and other
properties) Operating Expenses shall include only such portion thereof as are apportioned by Landlord to the Campus on a fair and equitable basis; 

  

	 	(10)	costs incurred with respect to a sale or transfer of all or any portion of the Campus or any interest therein or in any person of whatever tier owning an interest therein;

	 	(13)	any damages and attorneys’ fees and disbursements and other costs in connection with any judgment, settlement or arbitration award resulting from any tort liability of Landlord. 

(b) For each calendar year during the term of this Lease, Tenant shall pay to Landlord as Additional Rent for the Premises, in accordance with
the terms of this Section 5.3, an amount (“Tenant’s Operating Expense Payment”) equal to Tenant’s Proportionate Share of the amount by which Operating Expenses for such calendar year exceed Base Operating
Expenses (such excess being referred to herein as the “Operating Excess”). 
 (c) Following the end of each calendar year,
Landlord shall furnish to Tenant a written statement (“Landlord’s Operating Statement”) in reasonable detail covering the calendar year just expired showing: (A) with respect to the Operating Expenses, (i) the
Operating Expenses for such calendar year, (ii) the amount of Tenant’s Proportionate Share of the Operating Excess for such year, (iii) payments, if any, made by Tenant with respect to the Operating Excess, and (iv) the Monthly
Operating Expense Payment Amount (as defined below) for the calendar year immediately following the calendar year that just expired and (B) if there are any Third Party Leases in effect during the calendar year just expired, (i) the Net
Third Party Rents actually received during such calendar year, and (ii) the Minimum Rent and Additional Rent payments, if any, made by Tenant for such year. Landlord shall use reasonable efforts to deliver to Tenant Landlord’s Operating
Statement within one hundred twenty (120) days following the expiration of the applicable calendar year without being obligated to incur any commercially unreasonable costs in connection therewith, it being agreed that Landlord shall have no
liability to Tenant if Landlord fails for any reason to deliver to Tenant any Landlord’s Operating Statement prior to such date for any reason. 

(d) On account of its obligations in respect of Operating Expenses, Tenant shall pay to Landlord, monthly, in advance, together with each
monthly installment of Minimum 

  
 9 

 
Rent, an amount (the “Monthly Operating Expense Payment Amount”) equal to one-twelfth (1/12th) of Tenant’s Proportionate Share of the Operating Excess for the preceding
lease year excluding any extraordinary Operating Expenses incurred during the preceding calendar year that Landlord does not reasonably anticipate will be incurred during the then-current lease year; provided however, that in no event shall the
foregoing limit Tenant’s obligation to make any payments to Landlord under Section 5.3(e) in the event Landlord subsequently incurs such extraordinary Operating Expenses during the applicable calendar year. Landlord’s
determination of the Monthly Operating Expense Payment Amount for the applicable year shall be reflected in Landlord’s Operating Statement. 

(e) In the event Landlord furnishes Landlord’s Operating Statement subsequent to the commencement of the applicable calendar year, then
(a) until the first day of the month following the month in which Landlord’s Operating Statement is furnished to Tenant, Tenant shall continue to pay to Landlord on the first day of each month an amount equal to the Monthly Operating
Expense Payment Amount as reflected on the most recent Landlord’s Operating Statement delivered to Tenant, (b) after such Landlord Operating Statement is furnished to Tenant or together therewith, Landlord shall give notice to Tenant
stating whether the installments of Tenant’s Operating Expense Payment previously made for such calendar year pursuant to clause (a) of this sentence were greater or less than the installments of Tenant’s Operating Expense Payment to
be made for such calendar year in accordance with such Landlord Operating Statement, and (1) if there shall be a deficiency, Tenant shall pay the amount thereof within thirty (30) days after demand therefor or (2) subject to the
provisions of the last sentence of Section 5.3(f), if there shall have been an overpayment, Landlord shall, at Landlord’s option, pay to Tenant together with such notice, or credit against the next subsequent payments of rent,
the amount thereof. The Monthly Operating Expense Payment Amount reflected on Landlord’s Operating Statement for the applicable calendar year may be adjusted by Landlord once a year to account for any increases in Operating Expenses that
Landlord actually incurs during such calendar year and which were not reasonably anticipatable based on Landlord’s past practices if such increases result in a variance of ten percent (10%) or more in Operating Expenses required to be paid
by Landlord, by furnishing to Tenant a written statement explaining the basis for the revision together with Landlord’s reasonable estimate of the revised Monthly Operating Expense Payment Amount. 

(f) If Landlord’s Operating Statement shall indicate any overpayment or deficiency, then Landlord or Tenant, as the case may be, shall
pay the same to the party entitled to the same within thirty (30) days after delivery of Landlord’s Operating Statement or, in the case of sums payable to Tenant, at Landlord’s option and subject to the terms of this
Section 5.3(f), Tenant shall be granted a credit for the amount of the overpayment made by Tenant, to be applied against the next due payments of rent. If, at the time Tenant becomes entitled to any refund or credit of rent, Tenant is
then in monetary default or material non-monetary default under this Lease, in each case, beyond the expiration of any applicable notice and/or cure period, Landlord may offset the amount of such credit or refund payable to Tenant against amounts
properly due and owing by Tenant to Landlord. Provided Tenant is not then in default beyond the expiration of any applicable notice and/or grace period, any credit or refund due Tenant at the expiration or sooner termination of the Term of this
Lease shall be paid to Tenant within thirty (30) days after the expiration or sooner termination of this Lease. 

  
 10 

 5.4 In the event that the date of the expiration or other termination of this Lease shall be a
day other than the last day of a Tax Year or a calendar year, then, in such event, in applying the provisions of this Article 5 with respect to any Tax Year (for the purpose of calculating Tenant’s share of Taxes) or calendar year (for
the purpose of calculating Tenant’s share of Operating Expenses), appropriate pro rata adjustments in the escalation due hereunder shall be made to reflect the occurrence of such event on a basis consistent with the principles underlying the
provisions of this Article 5 taking into consideration that the expiration date of this Lease occurred during a partial lease year. 

5.5 In no event shall the Minimum Rent ever be reduced by operation of this Article 5. Landlord’s failure to render a
Landlord’s Tax Statement with respect to any Tax Year or a Landlord’s Operating Statement with respect to any calendar year, respectively, shall not prejudice Landlord’s right to thereafter render a Landlord’s Tax Statement or
Landlord’s Operating Statement with respect thereto or with respect to any subsequent Tax Year or calendar year provided that such Landlord’s Tax Statement or Landlord’s Operating Statement, as applicable, shall have been given to
Tenant within two (2) years after the expiration of the Tax Year or calendar year in question, as applicable. 
 5.6 Each of
Landlord’s Tax Statements and Landlord’s Operating Statements shall be conclusive and binding upon Tenant unless (i) pending the determination of such dispute by agreement or otherwise, Tenant shall pay additional rent in accordance
with the applicable Landlord’s Tax Statement and/or Landlord’s Operating Statement, as the case may be, without prejudice to Tenant’s position, and (ii) within one hundred twenty (120) days after receipt of such
Landlord’s Tax Statement and/or Landlord’s Operating Statement, Tenant shall notify Landlord in writing that it disputes the correctness thereof, which notice shall specify the particular respects in which the disputed Statement is
inaccurate to the extent known. Tenant shall have the right, during reasonable business hours and upon not less than ten (10) business days’ prior written notice to Landlord, to examine Landlord’s books and records with respect to any
Landlord’s Tax Statement or Landlord’s Operating Statement, provided that (a) such examination is commenced within one hundred twenty (120) days and concluded within one hundred eighty (180) days following the rendition of
the statement in question, (b) such examination may only be conducted by: (i) a certified public accountant or other qualified professional who is a member of an independent certified public accounting firm or other qualified professional
services firm having at least twenty-five (25) professionals or (ii) an employee of Tenant, who, in each instance, is not (and whose firm is not) being compensated by Tenant or any other person or entity, in whole or in part, on a
contingency basis and is not and has not during the Term been affiliated with, a shareholder, an officer, director, partner or employee of Landlord, and (c) upon Landlord’s request, Tenant and such accounting or other firm or employee of
Tenant deliver a confidentiality agreement to Landlord with respect to such dispute and such examination in form and substance reasonably satisfactory to Landlord. In connection with any examination by Tenant of Landlord’s books and records,
Tenant agrees to treat, and to instruct its employees, accountants and agents reviewing such records to treat, all information as confidential and not disclose it to any other person except as may be required by law or in connection with any dispute
with Landlord under this Lease relating thereto. Each party shall be responsible for its own fees in connection with such dispute. If Landlord and Tenant are unable to resolve a dispute regarding Landlord’s Tax Statement or Landlord’s
Operating Statement and provided that the amount that Tenant claims is due is substantially 

  
 11 

 
different from the amount Landlord claims is due, Tenant shall send a notice to Landlord, within one hundred twenty (120) days after the date on which the records are made available to
Tenant in connection with the disagreement in question indicating that Tenant desires to have such disagreement determined by an Arbiter (as hereinafter defined) and setting forth the name of an individual proposed by Tenant to serve as Arbiter. If
Landlord does not agree with Tenant’s selection of an Arbiter, Landlord and Tenant shall attempt to agree on another individual to serve as Arbiter, and if Landlord and Tenant shall be unable to agree upon the designation of the Arbiter within
thirty (30) days after Landlord’s receipt of Tenant’s notice requesting the appointment of an Arbiter, then either party shall have the right to request the American Arbitration Association (or any organization which is the successor
thereto) to designate an Arbiter. The “Arbiter” shall be a certified public accountant who is a member of an independent certified public accounting firm having at least twenty-five (25) accounting professionals. The
Arbiter’s determination, made in accordance with this Section 5.6, shall be conclusive and binding upon the parties; it being understood that if the amount Tenant claims is due is not substantially different from the amount Landlord
claims is due, then Tenant shall have no right to protest such amount and shall pay the amount that Landlord claims is due to the extent not theretofore paid. If the determination of the Arbiter shall substantially confirm the determination of
Landlord, then Tenant shall pay the cost of the Arbiter. If the Arbiter shall substantially confirm the determination of Tenant, then Landlord shall pay the cost of the Arbiter. In all other events, the cost of the Arbiter shall be borne equally by
Landlord and Tenant. In rendering such determination such Arbiter shall not add to, subtract from or otherwise modify the provisions of this Lease. Pending the resolution of any contest pursuant to this Section 5.6, and as a condition to
Tenant’s right to prosecute such contest (but without prejudice to Tenant’s position), Tenant shall pay all sums required to be paid in accordance with Landlord’s Operating Statement or Landlord’s Tax Statement in question. The
term “substantially different”, as used in this Section 5.6, shall mean a variance of five percent (5%) or more of the amount required to be paid by Tenant pursuant to Landlord’s Operating Statement or Landlord’s
Tax Statement in question and the term “substantially confirm”, as used in this Section 5.6, shall mean a variance of less than five percent (5%) of the amount required to be paid by Tenant pursuant to Landlord’s
Operating Statement or Landlord’s Tax Statement in question. 
 5.7 Landlord’s and Tenant’s obligations under this Article
5 shall survive the expiration or earlier termination of the term of this Lease. 
 ARTICLE 6 

LATE PAYMENT CHARGE 
 6.1
If Tenant shall fail to make any payment of Minimum Rent or Additional Rent for more than five (5) days after the same is due and payable, Tenant shall pay a late payment charge of $.05 for each $1.00 which remains unpaid to compensate Landlord
for additional expenses in processing such late payment. In addition, if Tenant fails to pay any Minimum Rent or Additional Rent when due, Tenant shall pay interest thereon from the date due until the date paid at an annual rate equal to the Prime
Rate plus one percent (1%) per annum but not in excess of the maximum amount permitted by law to be charged to Tenant, and such interest shall be deemed to be Additional Rent hereunder. 

6.2 If any check of Tenant shall be returned for insufficient funds, there shall be an additional charge to Tenant of $150.00 and, thereafter,
at the request of Landlord, Tenant shall make all payments required hereunder by certified or official bank check only. 

  
 12 

 ARTICLE 7 

ALTERATIONS 
 7.1 Tenant
shall make no alterations, installations, additions or improvements (collectively, “Alterations”) in or to the Premises or the Licensed Space of any nature without Landlord’s prior consent, which consent shall not be
unreasonably withheld, conditioned or delayed; provided, however, that with respect to Alterations which are structural in nature or which would adversely affect (i) a Building’s base mechanical, electrical, fire protection, plumbing, HVAC
systems or structure, (ii) the use by Landlord or any tenant of their respective premises, or (iii) Landlord’s insurance rates as determined by Landlord’s property insurance carrier, then Landlord may withhold, condition or delay
its consent in its sole and absolute discretion. Any Alterations to be performed by Tenant may only be performed by using contractors or mechanics from Landlord’s approved list of contractors or such other reputable contractors or mechanics as
Landlord shall approve (which approval shall not be unreasonably withheld, conditioned or delayed), it being agreed, however, that Tenant must use Landlord’s designated contractor for any Alterations relating to fire safety or structural
changes. Tenant agrees that all Alterations shall be performed by Tenant in accordance with all applicable Legal Requirements (including, without limitation, the Americans with Disabilities Act of 1990 and all regulations issued thereunder) and the
Campus policies then in effect. Tenant agrees to use a reputable engineer and architect licensed in the Commonwealth of Pennsylvania approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed) for the preparation
of all construction documents and drawings pertaining to any Alterations and to file all plans with and obtain all required permits from appropriate governmental authorities. Notwithstanding the foregoing, prior to the commencement of any
Alteration, Tenant shall provide Landlord’s designated engineer any construction documents or drawings prepared by or on behalf of Tenant in connection with any Alteration that affects a Building’s base mechanical, electrical, fire
protection, plumbing, HVAC systems or structure, recognizing that the integrity of the Building’s systems shall be maintained through such review by the Building engineer. Tenant’s architect shall file all required architectural drawings
and obtain all necessary permits at Tenant’s cost. Upon receipt thereof, Tenant shall promptly submit to Landlord, copies of all approved plans, permits, applications, final approvals and sign-offs. 

7.2 Notwithstanding anything to the contrary contained in this Article 7, Landlord’s consent shall not be required with respect to
(i) decorative alterations such as painting, wall coverings and floor coverings (“Decorative Alterations”) or (ii) non-structural Alterations by Tenant which (a) shall be located wholly within the Premises,
(b) shall not affect the structural integrity of the Building or the operation of the HVAC, plumbing, electrical, or water and sewer systems of the Building, (c) are not visible from outside of the Premises, and (d) do not cost more
than $50,000 for any single Alteration, provided, in each instance that (1) such Alterations shall otherwise be performed in accordance with all of the terms and conditions of this Lease, (2) Tenant gives Landlord at least ten
(10) days’ prior notice of such work and, for informational purposes, the plans and specifications therefor but only to the extent the same would be 

  
 13 

 
customarily prepared or be required to be prepared in order to obtain any necessary permits, (3) such Alteration shall be performed in a good and workmanlike manner, (4) Tenant is not
in default or default under this Lease beyond the expiration of any applicable notice and/or cure period, and (5) such Alterations do not adversely affect Landlord’s insurance rates as determined by Landlord’s property insurance
carrier. 
 7.3 Except for the Excluded FF&E (as hereinafter defined), trade fixtures that are installed by or on behalf of Tenant at
Tenant’s sole cost and expense during the Term, and moveable furniture and equipment purchased by Tenant at its sole cost and expense (collectively, “Tenant’s Property”), all fixtures and all paneling, partitions, railings
and like installations, installed in the Premises and Licensed Space at any time (whether prior to or during the applicable term thereof), either by Tenant or by Landlord on Tenant’s behalf, shall, upon installation, become the property of
Landlord and, subject to the provisions of Section 7.5, Article 36 and Article 40 below, shall remain upon and be surrendered with the Premises or the Licensed Space, as applicable. Nothing in this Article 7 shall be
construed to give Landlord title to or to prevent Tenant’s removal of Tenant’s Property, but upon removal of any such items of Tenant’s Property from the Premises or upon removal of other installations as may be required pursuant to
the terms hereof, Tenant shall promptly and at its expense, and repair any damage to the Premises or the Building due to such removal. All property permitted or required to be removed by Tenant at the end of the term remaining in the Premises after
Tenant’s removal shall be deemed abandoned and may, at the election of Landlord, either be retained as Landlord’s property or may be removed from the Premises by Landlord at Tenant’s expense. 

7.4 Tenant shall, before making any Alterations, at its expense, obtain all permits, approvals and certificates required by any governmental
or quasi-governmental bodies and (upon completion) certificates of final approval thereof and shall deliver promptly duplicates of all such permits, approvals and certificates to Landlord. If any mechanic’s lien is filed against the Premises or
any Building for work claimed to have been performed by or on behalf of Tenant (but not by Landlord) or for materials claimed to have been furnished to Tenant (but not by Landlord), it shall be discharged by Tenant within thirty (30) days after
Tenant receives notice thereof (from whatever source), at Tenant’s expense, by filing the bond required by law or payment or otherwise. If Tenant fails to discharge such lien within such thirty (30) day period, then Landlord shall have the
right to discharge same (by filing the bond required by law or by payment in full of the mechanic’s lien or otherwise) and Landlord’s costs and expense in obtaining such discharge shall be repaid in full by Tenant to Landlord as additional
rent within twenty (20) days after demand therefor. 
 7.5 As to any Alteration allowed to be made by Tenant pursuant to this Lease,
Tenant shall not be required to remove such Alterations at or prior to the expiration or earlier termination of this Lease unless (i) at the time Landlord approves the plans and specifications for any such proposed Alterations, Landlord
specifically designates those items it reserves the right to require Tenant to remove at the end of the Term or (ii) Landlord, by notice to Tenant no later than sixty (60) days prior to the stated Expiration Date, directs Tenant to remove
such items from the Premises, in which event, the same shall be removed from the Premises by Tenant prior to the expiration of this Lease at Tenant’s sole cost and expense, and Tenant shall, at its sole cost and expense, restore the Premises
with respect thereto to the same condition as that which existed on the Commencement Date, reasonable wear and tear excepted. 

  
 14 

 7.6 Tenant agrees that with respect to the performance of any Alterations in the Premises, Tenant
shall pay to Landlord, as additional rent hereunder, promptly upon being billed therefor, Landlord’s reasonable out-of-pocket and other expenses including, without limitation, the fees of any architect, engineer or expeditor employed or hired
by Landlord, indirect costs, costs of field supervision and coordination incurred by Landlord; it being agreed that Tenant shall not be obligated to pay any such indirect costs or costs of field supervision and coordination in connection with
Tenant’s Initial Work. 
 7.7 (a) Before proceeding with any Alteration estimated to cost in excess of $50,000.00 (other than
Decorative Alterations), Tenant shall furnish to Landlord one of the following: (i) a cash deposit or (ii) a performance bond and a labor and materials payment bond (issued by a corporate surety licensed to do business in Pennsylvania
reasonably satisfactory to Landlord), (iii) an irrevocable, unconditional, negotiable letter of credit, issued by and drawn on a bank or trust company which is a member of the Clearing House in a form reasonably satisfactory to Landlord; each
in an amount equal to one hundred twenty-five (125%) percent of the estimated cost of the Alteration or (iv) such other security as Landlord may be reasonably acceptable to Landlord. 

(b) Upon (i) the completion of the Alteration in accordance with the terms of this Article 7 and (ii) the submission to
Landlord of proof evidencing the payment in full for said Alteration including, but not limited to, delivery of a waivers of mechanic liens, the security deposited under Section 7.7(a) with Landlord (or the balance of the proceeds
thereof, if Tenant has furnished cash or a letter of credit and if Landlord has drawn on the same) shall be returned to Tenant. 
 (c) Upon
Tenant’s failure to properly perform, complete and fully pay for the said Alteration, as reasonably determined by Landlord, Landlord shall be entitled to draw on the security deposited under Section 7.7(a) to the extent it deems
necessary to complete any incomplete Alteration or otherwise hazardous condition, to effect any necessary restoration and/or protection of the Premises or the Property and to apply such funds to the payment or satisfaction of any costs, damages or
expenses in connection with the foregoing and/or Tenant’s obligations under this Article 7 and this Lease relating to Alterations and repairs, including the satisfaction of any mechanic’s lien. 

7.8 All Alterations shall be performed by Tenant in compliance with all applicable requirements of insurance bodies and with Legal
Requirements and the same shall be diligently performed in a good and workmanlike manner. 
 7.9 Tenant agrees that Tenant will not at any
time during the term hereof, either directly or indirectly, use any contractors and/or labor and/or materials if the use of such contractors and/or labor and/or materials would or will create any difficulty with other contractors and/or labor
engaged by Tenant or Landlord or others in the performance of any work at a Building or any part thereof. 
 7.10 Tenant shall cause each
contractor to carry personal injury and property damage and general liability insurance for any occurrence in or about the applicable Building in a combined single limit of not less than $2,000,000. Before commencing any work or delivering

  
 15 

 
material to the applicable Building, each such contractor shall deliver certificates evidencing such insurance to Landlord and naming Landlord as an insured party under the policy. Each
contractor performing work at the applicable Building shall also carry workmen’s compensation insurance in statutory limits covering all persons employed in connection with the work for death or injury. Notwithstanding the foregoing, the
obligation for a contractor to carry the insurance under this Section 7.10 shall be waived by Landlord to the extent such Alteration constitutes a Decorative Alteration and such waiver is consistent with past practice in Landlord’s
reasonable determination. 
 7.11 Tenant and all contractors shall comply promptly with the procedures and regulations reasonably prescribed
by Landlord for the use of the freight elevators and the other Common Areas; it being that the foregoing is not intended to imply that Tenant or its contractors have the right to use any such areas if the same is prohibited by any other provisions
of this Lease. 
 7.12 No approval or deemed approval of any plans or specifications by Landlord or consent by Landlord allowing Tenant to
make any improvements (including Tenant’s Initial Work) or any inspection of improvements made by or for Landlord shall in any way be deemed to be an agreement by Landlord that the contemplated improvements comply with any Legal Requirements or
insurance requirements or the certificate of occupancy for the applicable Building nor shall it be deemed to be a waiver by Landlord of the compliance by Tenant of any provision of this Lease. 

7.13 Provided Tenant is not in default hereunder beyond the expiration of any applicable notice and/or cure period, Landlord shall promptly
after Tenant’s request, at no out of pocket cost, expense or liability to Landlord, cooperate with and assist Tenant in all reasonable respects in attempting to procure all permits and approvals that may be required for the performance of any
approved or otherwise permissible Alterations to be performed by Tenant provided that any applications and other documents comply in all respects with all Legal Requirements and the applicable provisions of this Lease; provided, however, as to any
such request, the subject matter thereof and/or the work contemplated thereby shall not constitute (or, if effectuated by Tenant, would not constitute) a breach by Tenant of any of its obligations under this Lease. Nothing contained in this Lease
shall be deemed or construed as a representation, warranty, or guaranty of any nature whatsoever, that any such permit, approval, certificate, or application, plans or other document is, or will be made, available to Tenant (or approved) by the
applicable governmental authority notwithstanding the cooperation of Landlord as set forth above or in any other provision of this Lease.

not be liable in any way to Tenant for any failure or defect in the supply or character of electric energy, or other utilities furnished to the Premises or the Licensed Space. Any additional risers, feeders, or other equipment proper or necessary to
supply Tenant’s electrical requirements with respect to the Premises, upon written request of Tenant, will be installed by Landlord at the sole cost and expense of Tenant, if, in Landlord’s reasonable judgment, the same will not cause or
create a hazardous condition or entail excessive or unreasonable alterations, repairs or expense or interfere with or disturb Landlord or any other tenants or cause permanent damage or injury to any Building. 

(b) If required under applicable Legal Requirements and subject to the terms of Section 8.9, Landlord shall be permitted to
terminate the furnishing of electrical energy, upon at least thirty (30) days’ notice (provided that such longer notice as is reasonably feasible under the circumstances shall be given) to Tenant unless a shorter period of notice is

beyond the control of 

  
 19

 ARTICLE 9 

 REQUIREMENTS OF LAW, FIRE INSURANCE, FLOOR LOAD 

9.1 Prior to the commencement of the Term, if Tenant is then in possession or otherwise given access to the Premises or the Licensed Space and
at all times thereafter during the applicable term thereof, Tenant, at Tenant’s sole cost and expense, shall promptly comply with all present and future Legal Requirements, whether or not arising out of Tenant’s use or manner of use
thereof, or, with respect to the Buildings or Licensed Space, if arising out of Tenant’s particular use or manner of use of the Premises, the Licensed Space or the Buildings. Nothing herein shall require Tenant to make structural repairs or
alterations under this Article 9 unless (i) the use of the Premises, the Licensed Space or the method of operation therein violated any such Legal Requirements or orders, rules, regulations or requirements with respect thereto, or
(ii) the same relate or are otherwise necessary as a result of any Alterations. Tenant may, after securing Landlord to Landlord’s reasonable satisfaction against all damages, interest, penalties and expenses, including, but not limited to,
reasonable attorneys’ fees and disbursements, by cash deposit or by surety bond in an amount and in a company reasonably satisfactory to Landlord, contest and appeal any such Legal Requirements, orders, rules, regulations or requirements
provided same is done with all reasonable promptness and provided such appeal shall not subject Landlord to any civil liability, prosecution for a criminal offense or constitute a default under any lease or mortgage under which Landlord may be
obligated, or cause the Premises, the Licensed Space or any part thereof to be condemned or vacated. Tenant shall not do or permit any act or thing to be done in or to the Premises or the Licensed Space which is contrary to Legal Requirements, or
which will invalidate or be in conflict with public liability, fire or other policies of insurance at any time carried by or for the benefit of Landlord with respect to the Premises, the Licensed Space or the Buildings, or which shall or might
subject Landlord to any liability or responsibility to any person or for property damage, nor shall Tenant keep anything in the Premises or the Licensed Space except as now or hereafter permitted by the Fire Department or other authority having
jurisdiction, and then only in such manner and such quantity so as not to increase the rate for fire insurance applicable to the Building, nor use the Premises or the Licensed Space in a manner which will increase the insurance rate for the Campus,
any Building or any property located therein over that in effect prior to the commencement of Tenant’s occupancy. Tenant shall pay all costs, expenses, fines, penalties, or damages, which may be imposed upon Landlord by reason of Tenant’s
failure to comply with the provisions of this Article 9. Tenant shall not place a load upon any floor of the Premises or Licensed Space 

  
 20 

 
exceeding the floor load per square foot area which it was designed to carry and which is allowed by law. Landlord reserves the right to prescribe the weight and position of all safes, business
machines and mechanical equipment. Such installation shall be placed and maintained by Tenant, at Tenant’s expense, in settings sufficient, in Landlord’s reasonable judgment, to absorb and prevent vibration, noise and annoyance. 

9.2 Subject to the terms of this Lease including, without limitation, Section 5.3 hereof, Landlord shall be responsible at its own
cost and expense to comply with (or cause to be complied with) all Legal Requirements applicable to the Buildings which are not the obligation of Tenant hereunder; provided, however, that Landlord shall not have any liability to Tenant for
any failure to comply with the foregoing obligation unless Landlord’s failure to comply with a particular Legal Requirement adversely affects (more than to a de minimis extent) Tenant’s use and enjoyment of the Premises and access
thereto. 
 ARTICLE 10  

SUBORDINATION 
 10.1 The
rights of Tenant under this Lease shall be and are subject and subordinate at all times to all ground leases, and/or underlying leases, if any, now or hereafter in force against the Property, and to each and every mortgage that may now or hereafter
be placed by Landlord on its interest in the Property, and to all increases, renewals, modifications, consolidations, replacements and extensions thereof. This Article 10 is self-operative and no further instrument of subordination shall be
required. In confirmation of such subordination Tenant shall promptly execute such further instruments as may be reasonably requested by Landlord. Tenant hereby irrevocably appoints Landlord as attorney-in-fact for Tenant with full power and
authority to execute and deliver in the name of Tenant any such instrument or instruments if Tenant fails to execute the same within ten (10) business days after request. To the extent not so provided by applicable Legal Requirements, in the
event of the enforcement by such mortgagee or lessor of the remedies provided for by Legal Requirements or by the mortgage or lease, if such mortgagee or lessor or any successors or assigns of such mortgagee or lessor shall, at its or their sole
option, succeed to the interest of Landlord under this Lease, whether through possessory or foreclosure action or a deed in lieu of foreclosure or otherwise, and this Lease shall not be terminated or affected by such foreclosure or any such
proceedings, Tenant, at the election of such mortgagee or lessor or its successors or assigns, shall attorn to and recognize such mortgagee or lessor (or its successors or assigns) as its landlord upon the terms, covenants, conditions and agreements
contained in this Lease to the same extent and in the same manner as if this Lease was a direct lease between such mortgagee or lessor (or its successors or assigns) and Tenant, except that such mortgagee or lessor (or its successors or assigns),
whether or not it shall have succeeded to the interest of Landlord under this Lease, shall not (i) have any liability for refusal or failure to perform or complete any work required to be performed by Landlord under this Lease to prepare the
Premises for occupancy in accordance with the provisions of this Lease or otherwise, (ii) be liable for any act, omission or default of any prior landlord under this Lease except for a default continuing after any such succession, (iii) be
subject to any offsets, claims or defenses which shall have heretofore accrued to Tenant against any prior landlord under this Lease, (iv) be bound by any rent or additional rent which Tenant might have paid to any prior landlord for more than
one (1) month in advance, (v) be liable for the return of any security deposit unless 

  
 21 

 
such security shall actually be received by such superior mortgagee or superior lessor and/or (vi) be bound by any cancellation, abridgement, surrender, modification or amendment of this
Lease, without the prior written consent of such mortgagee or lessor or such successor in interest. Upon request by said successor in interest, Tenant shall execute and deliver an instrument or instruments confirming such attornment. 

ARTICLE 11

performed. In case any action or proceeding is brought against Tenant by reason of any such claim, Landlord, upon notice from Tenant will, at Landlord’s expense, resist or defend such action or proceeding by counsel approved by Tenant in
writing, such approval not to be unreasonably withheld or delayed (it being agreed that counsel to Landlord’s insurance carrier is acceptable). In connection with such indemnity, (a) Tenant shall endeavor to promptly notify Landlord of the
relevant claim or action (it being agreed that the timing of said notice shall not be a condition to the effectiveness of the foregoing indemnity), (b) Tenant shall reasonably cooperate with Landlord in Landlord’s defense of such claim or
action, provided that Tenant shall not incur any expense thereby, (c) prior to Tenant’s settlement of any such claim or action, Tenant shall request Landlord’s consent thereto, such consent not to be unreasonably withheld, conditioned

claims, costs and expenses including reasonable attorneys’ fees and disbursements, paid, suffered or incurred by Landlord Party in connection with, relating to, arising out of or resulting from, directly or indirectly, any of the following
items (without duplication): (i) any breach by Tenant, Tenant’s agents, contractors, employees, invitees, guests or licensees, of any covenant or condition of this Lease on Tenant’s part to be performed; (ii) the gross negligence
or willful misconduct of Tenant, any Tenant Party and any of Tenant’s agents, contractors, employees, invitees, guests or licensees or any other person or entity claiming by, through or under Tenant; (iii) the use or occupancy of the
Premises, the Licensed Space and/or the Common Areas by Tenant, any Tenant Party or any person or entity claiming by, through or under Tenant; (iv) any acts, omissions or gross negligence of Tenant, any Tenant Affiliate or any such person or

condition created by Tenant, any Tenant Affiliate or any such person or entity, or the contractors, agents, employees, invitees or licensees of Tenant or any such person or entity, in or about the Property, the Licensed Space or the Common Areas.
Tenant shall pay to Landlord as Additional Rent, within twenty (20) days following rendition by Landlord to Tenant of bills or statements therefor, sums equal to all losses, costs, liabilities, claims, damages, fines, penalties and expenses
referred to in this Section 11.2. Tenant’s liability under this Lease extends to the acts and omissions of any subtenant, and any agent, contractor, employee, invitee or licensee of any subtenant or any person or entity claiming by,

promptly notify Tenant of the relevant claim or action (it being agreed that the timing of said notice shall not be a condition to the effectiveness of the foregoing indemnity), (b) Landlord shall reasonably cooperate with Tenant in
Tenant’s defense of such claim or action, provided that Landlord shall not incur any expense thereby, (c) prior to Landlord’s settlement of any such claim or action, Landlord shall request Tenant’s consent thereto, such consent
not to be unreasonably withheld, conditioned or delayed and (d) if Tenant shall request that Landlord settle such claim or action, and Tenant shall deliver to Landlord the necessary funds to do so (together with all other amounts due or payable
to Landlord in connection with this indemnity), Landlord shall accede to such request in any case where the only relief being sought by the claimant or plaintiff in any proposed settlement is monetary damages and Landlord and parties related to
Landlord are absolutely and unconditionally released in connection therewith. 
 11.3 Tenant shall look only to Landlord’s estate and
interest in the Buildings (or the net proceeds of any sale thereof) for the satisfaction of Tenant’s remedies or for the collection of a judgment (or other judicial process) requiring the payment of money by Landlord in the event of any default
by or liability of Landlord under this Lease, and no other property or assets of 

  
 23 

 
Landlord and no property of any officer, member, employee, director, shareholder, partner or principal of Landlord shall be subject to levy, execution or other enforcement procedure for the
satisfaction of Tenant’s remedies under or with respect to this Lease, the relationship of Landlord and Tenant hereunder or Tenant’s use or occupancy of the Premises or the Licensed Space.

with any matter arising from or relating to this Lease for any consequential, special or indirect damages.

attributable to such damage, to repair or cause to be repaired such damage to the Premises but only to the extent not a part of any Alterations or otherwise not the responsibility of Tenant under this Lease to construct, install, repair, replace
and/or maintain. All repairs to the Premises required by reason of such fire or other casualty that are not the responsibility of Landlord hereunder shall be performed by Tenant, at its sole cost and expense, promptly and with due diligence unless
this Lease shall have been terminated pursuant to this Article 12, in which event Tenant need not make such repairs. Except as provided in Section 12.8, the Minimum Rent and the Additional Rent payable under Article 5 shall
be equitably abated to the extent that the Premises shall have been rendered untenantable, such abatement to be from the date of such damage to the date the repairs required hereinabove to be performed by Landlord shall have been substantially
completed; provided, however, should Tenant reoccupy a portion of the Premises for the conduct of Tenant’s business prior to the date such repair work shall have been substantially completed, the Minimum Rent and the Additional Rent payable
under Article 5 allocable to such reoccupied portion of the Premises, based upon the proportion which the occupied portion of the Premises bears to the total area of the Premises, shall be payable by Tenant from the date of such occupancy.

 12.3 If the Premises are rendered wholly unusable or if a substantial part (i.e., more than seventy-five percent (75%)) of
the Premises shall be damaged, either Landlord or Tenant may elect to terminate this Lease by notice to the other party given within ninety (90) days after such fire or casualty specifying a date for the expiration of this Lease, which date
shall not be more than sixty (60) days after the giving of such notice, and upon the date specified in such notice the term of this Lease shall expire as fully and completely as if such date were the date set forth above for the expiration of
this Lease and Tenant shall forthwith quit, surrender and vacate 

  
 24 

 
the Premises without prejudice however, to Landlord’s rights and remedies against Tenant under the provisions hereof in effect prior to such termination, and any rent owing shall be paid up
to the date of such casualty and, provided Tenant is not otherwise in default hereunder beyond the expiration of any applicable notice and/or cure period, any payments of rent made by Tenant which were on account of any period subsequent to such
date shall be returned to Tenant. 
 12.4 Notwithstanding anything herein to the contrary, if the Premises are totally or substantially
damaged (or rendered unusable for the ordinary conduct of Tenant’s business) by a fire or other casualty at any time during the Term and provided this Lease is not terminated by Landlord or Tenant as provided in this Article 12, if
either (i) Landlord shall not have commenced repairs as provided in Section 12.2 within sixty (60) days after Landlord’s collection of insurance proceeds or (ii) Landlord has not completed the making of the repairs
required by it to be made under Section 12.2 within twelve (12) months from the date of such fire or other casualty, with such additional time after such date, as shall equal the aggregate period Landlord may have been delayed in
doing so by force majeure or adjustment of insurance, as applicable, Tenant, within twenty (20) days after the date on which such applicable time period expires, may serve notice on Landlord of its intention to terminate this Lease, and if
within said twenty (20) day period, Landlord shall not have so commenced repairs or substantially completed the making of such required repairs, as the case may be, this Lease shall terminate on the expiration of such twenty (20) day
period as if such termination date were the Expiration Date and Tenant shall forthwith quit, surrender and vacate the Premises without prejudice, however, to each party’s rights and remedies against the other under the provisions hereof in
effect prior to such termination, and any rent owing shall be paid up to the date of such casualty and, provided that Tenant is not otherwise in default hereunder beyond the expiration of any applicable notice and/or cure period, any payments of
rent made by Tenant which were on account of any period subsequent to such date shall be returned to Tenant. 
 12.5 Unless Landlord shall
serve a termination notice as provided for herein or this Lease is terminated by Tenant pursuant to Section 12.3 or Section 12.4, Tenant shall cooperate with Landlord’s restoration obligations by removing from the
Premises as promptly as reasonably possible, all of Tenant’s salvageable inventory and movable equipment, furniture, and other property. 

12.6 Nothing contained hereinabove shall relieve Tenant from liability that may exist as a result of damage from fire or other casualty.
Notwithstanding the foregoing, each party shall look first to any insurance in its favor before making any claim against the other party for recovery for loss or damage resulting from fire or other casualty, and, except as provided in
Section 12.8, to the extent that such insurance is in force and collectible and to the extent permitted by law, Landlord and Tenant each hereby releases and waives all right of recovery against the other or any one claiming through or
under each of them by way of subrogation or otherwise. The foregoing release and waiver shall be in force only if both releasors’ insurance policies contain a clause providing that such a release or waiver shall not invalidate the insurance and
also, provided that such a policy can be obtained without additional premiums. 
 12.7 Tenant acknowledges that Landlord will not carry
insurance on Tenant’s furniture, furnishings and other personal property or any Alterations installed by or on behalf of Tenant and agrees that Landlord will not be obligated to repair any damage thereto or replace the same

  
 25 

 
and unless this Lease is terminated as provided in this Article 12, Tenant shall promptly repair, restore and/or replace the same regardless if the insurance proceeds therefor are
sufficient for the same. 
 12.8 Notwithstanding any of the foregoing provisions of this Article 12, if and to the extent by reason
of some wrongful act on the part of Tenant or any of its employees, agents, contractors, subcontractors, licensees or concessionaires after the occurrence of a casualty which wrongful act is not cured prior to the expiration of any applicable notice
and/or cure period, either (i) Landlord shall be unable to collect all of the insurance proceeds (including rent insurance proceeds) applicable to damage or destruction of the Premises or any Building by fire or other casualty or (ii) the
Premises or any Building shall be damaged or destroyed or rendered completely or partially untenantable on account of fire or other casualty, then, without prejudice to any other remedy which may be available against Tenant, (a) the abatement
of rent provided for in this Article 12 shall not be effective to the extent of the uncollected insurance proceeds and (b) Landlord shall have no obligation to make any repairs whatsoever to the portions of the Premises required to be
repaired by Landlord under Section 12.2 hereof. 
 ARTICLE 13  

EMINENT DOMAIN 
 If the
whole or any material part of the Premises shall be acquired or condemned by eminent domain for any public or quasi-public use or purpose, then and in that event, the term of this Lease shall cease and terminate from the date of title vesting in
such proceeding and Tenant shall have no claim for the value of any unexpired term of this Lease. Tenant acknowledges that Landlord shall be entitled to receive the entire compensation or award therefor. Notwithstanding the foregoing, Tenant may
make a separate claim in any eminent domain proceeding (affecting all or any portion of the Premises) solely for the then value of Tenant’s property and/or for any moving expenses incurred by Tenant in connection therewith, provided that such
award shall not result in a reduction of the award made to Landlord in connection therewith. If only a non-material part of the Premises shall be acquired or condemned by eminent domain as aforesaid and this Lease shall not be terminated, this Lease
and the term of this Lease shall continue in full force and effect, provided, however, that from and after the date of the vesting of title, the Minimum Rent and Additional Rent shall be equitably reduced to include only that portion of the Premises
that was not acquired or condemned by eminent domain. 
 ARTICLE 14  

ASSIGNMENT, SUBLETTING, ETC. 

14.1 Tenant expressly agrees that neither this Lease nor any part hereof, shall, by operation of law or otherwise, be assigned, mortgaged,
pledged, encumbered or otherwise transferred (a “Transfer”) by Tenant, Tenant’s legal representatives or successors in interest and neither the Premises, nor any part thereof, nor any Tenant’s property shall be encumbered
in any manner by reason of any act or omission on the part of Tenant or anyone claiming under or through Tenant, or shall be sublet or be used, occupied or utilized for concession or desk space 

  
 26 

 
or for mailing privileges by anyone other than Tenant, without the prior consent of Landlord in each instance except as otherwise expressly provided in this Article 14. For purposes of
this Article 14, (i) the issuance of interests in Tenant (whether stock, partnership interests, interests in a limited liability company or otherwise) to any person or group of related persons, whether in a single transaction or a series
of related or unrelated transactions, in such quantities that after such issuance control of Tenant or the ability effectively to control or direct the business decisions of Tenant, directly or indirectly, shall have changed, shall be deemed an
assignment of this Lease, as the case may be, (ii) a Transfer of more than 50% in beneficial interest of Tenant (whether stock, partnership interests, interests in a limited liability company or otherwise) by any party or parties in interest
whether in a single transaction or a series of related or unrelated transactions shall be deemed an assignment of this Lease, (iii) a take-over agreement shall be deemed an assignment of this Lease and (iv) any person or legal
representative of Tenant, to whom Tenant’s interest under this Lease passes by operation of law, or otherwise, shall be bound by the provisions of this Article 14. Any assignment (or deemed assignment), sublease (or deemed sublease),
license, concession, mortgage, pledge, encumbrance or transfer by Tenant in contravention of this Article 14 shall be void. Notwithstanding the foregoing, if Tenant is a corporation whose stock is publicly traded on a nationally recognized
stock exchange (including, without limitation, an initial public offering), then the issuance of stock or one or more transfers of stock or other beneficial interest in Tenant (whether or not more than 50% of the stock or other beneficial interest
in Tenant is so transferred other than to those deemed “insiders” within the meaning of the Securities Exchange Act of 1934, as amended) which is effected through “over-the-counter market” or through any recognized stock exchange
shall not constitute an assignment hereunder. 
 14.2 If this Lease be assigned, or if the Premises or any part thereof be underlet or
occupied by anybody other than Tenant, whether or not in violation of this Article 14, Landlord may, after default by Tenant, collect rent from the assignee, under-tenant or occupant, and apply the net amount collected to the rent herein
reserved, but no such assignment, underletting, occupancy or collection shall be deemed a waiver of this covenant, or the acceptance of the assignee, under-tenant or occupant as tenant, or a release of Tenant from the further performance by Tenant
of covenants on the part of Tenant herein contained. The consent by Landlord to an assignment or underletting shall not in any way be construed to relieve Tenant from obtaining the express consent in writing of Landlord to any further assignment or
underletting except to the extent such consent is not required under the express terms of this Article 14. 
 14.3 In connection with
any request for consent to an assignment of this Lease or the subletting of the Premises in whole or in part, Tenant shall provide Landlord with all information reasonably requested by Landlord, including but not limited to, financial reports with
respect to such proposed assignee or subtenant. 
 14.4 (a) No assignment or sublease shall be valid, and no assignee or subtenant shall
take possession of the Premises until an executed counterpart of such assignment or sublease has been delivered to Landlord, which sublease or assignment agreement, as applicable, shall be in form reasonably satisfactory to Landlord and shall comply
with the applicable provisions of this Article 14. 

  
 27 

 (b) Each sublease shall expressly provide that it is subject and subordinate to this Lease and to
the matters to which this Lease is or shall be subordinate, and that, in the event of any termination, re-entry, or dispossess by Landlord under this Lease, Landlord may, at its option, take over all of the right, title and interest of Tenant as
sublandlord under such sublease, and such subtenant shall, at Landlord’s option, attorn to Landlord pursuant to the then executory provisions of such sublease, except that Landlord shall not (i) be liable for any previous act or omission
of Tenant under such sublease, (ii) be subject to any offset, not expressly provided in such sublease, that theretofore accrued to such subtenant against Tenant or (iii) be bound by any previous modification of such sublease not approved
in writing by Landlord or by any prepayment of more than one month’s minimum rent or any additional rent then due. 
 (c) Any
assignment or transfer shall be made only if, and shall not be effective until, the assignee shall execute, acknowledge and deliver to Landlord an agreement, in form and substance reasonably satisfactory to Landlord, whereby the assignee shall
assume all of the obligations of this Lease on the part of Tenant to be performed or observed. 
 14.5 Notwithstanding any provision to the
contrary contained herein, Tenant may, without obtaining Landlord’s consent (but subject to compliance with the requirements of this Section 14.5), (i) assign or transfer this Lease to a corporation or other entity into which
Tenant shall be merged or consolidated (a “successor entity”) or an entity which acquires all or substantially all of the assets, stock, or other equity interest of Tenant (an “acquiring entity”) or (ii) sublet the entire
Premises to an entity which controls, is controlled by, or is under common control with Tenant (a “related entity”), provided that in all such cases: (a) Tenant shall not be in default hereunder beyond the expiration of any applicable
notice and/or cure period at the time of such assignment, transfer or sublease; (b) the principal purpose of such transfer or acquisition is not the acquisition of Tenant’s interest in this Lease and is not made to circumvent the
provisions of this Article 14; (c) in the case of an assignment to a successor entity or acquiring entity, reasonably satisfactory proof has been delivered to Landlord demonstrating that such successor entity or acquiring entity has a
net worth immediately following such merger or acquisition computed in accordance with generally accepted accounting principles at least equal to the net worth of Tenant herein named on the date of this Lease; (d) in the case of a subletting to
a related entity, the rights granted to Tenant and such related entity pursuant to this Section 14.5 shall be for only so long as such person or entity shall remain a related entity and at such time as such person or entity shall no
longer be a related entity the rights accorded to Tenant by this Section 14.5 shall not apply and Tenant shall promptly comply with all of the terms and conditions of this Article 14, and (e) in the event of an assignment,
there shall have been delivered to Landlord, at least ten (10) days after the effective date of such assignment, an instrument in form and substance reasonably satisfactory to Landlord, duly executed by the assignee, in which such assignee
assumes (as of the effective date of such assignment) observance of and performance of, and agrees to be bound by, all of the terms, covenants and conditions of this Lease on Tenant’s part to be performed. 

14.6 Notwithstanding any provision to the contrary contained herein, Tenant may, without obtaining Landlord’s consent (but subject to
compliance with the requirements of this Section 14.6) enter into desk sharing arrangements (each, a “Desk Sharing Arrangement”), provided that in all such cases: (a) Tenant shall not be in default hereunder beyond
the expiration of any applicable notice and/or cure period at the time of such Desk Sharing 

  
 28 

 
Arrangement; (b) such arrangement shall be subject and subordinate to the terms of this Lease; (c) such arrangement will terminate automatically upon a default by Tenant occurring and
continuing beyond any applicable notice and cure period under this Lease; (d) the party under the Desk Sharing Arrangement shall use the Premises in conformity with all applicable provisions of this Lease; (e) in no event shall the use of
any portion of the Premises by any entity under any Desk Sharing Arrangement create or be deemed to create any right, title or interest in or to the Premises for such entity; (f) the portion(s) of the Premises occupied by such party(ies) and
the portion of the Premises occupied by Tenant shall not be, and shall not be required by law to be, separated by demising walls so as to create separate entrances from the elevator landing or public corridors; (g) the aggregate space covered
by all Desk Sharing Arrangements shall not be more than fifteen percent (15%) of the rentable square footage of the Premises, in the aggregate; and (h) no such arrangement shall be deemed to release Tenant from any of its obligations and
liabilities hereunder. 
 14.7 In no event shall any assignment or subletting (including any assignment not requiring Landlord’s
consent hereunder) release or relieve Tenant from its obligations fully to perform all of the terms, covenants and conditions of this Lease on Tenant’s part to be performed. 

14.8 Tenant shall reimburse Landlord (whether or not the proposed transaction is consummated), within ten (10) days after demand, for all
reasonable costs incurred by Landlord in connection with any assignment (whether or not Landlord’s consent is required therefor) or sublease, including the costs of making investigations as to the acceptability of the proposed assignee or
subtenant (or whether such proposed assignee or subtenant satisfies the conditions set forth in this Article 14) and reasonable attorney’s fees and disbursements incurred in connection with the granting or reviewing of any matters
reasonably related to any such assignment, subletting or other transfer. 
 ARTICLE 15  

ACCESS TO PREMISES 
 15.1
Subject to the provisions of Section 15.2, Landlord or Landlord’s agents shall have the right (but shall not be obligated) to enter the Premises and the Licensed Space in any emergency at any time, and, at other reasonable times,
upon reasonable prior notice to Tenant, to examine the same, to confirm Tenant’s compliance with the terms and provisions of this Lease, and/or to make such repairs, replacements and improvements as Landlord may perform pursuant to the terms of
Section 8.1, or which Landlord may deem necessary or reasonably desirable to the Premises, the Licensed Space or to any other portion of the Building or which Landlord may elect to perform following Tenant’s failure to make repairs
or perform any work which Tenant is obligated to perform under this Lease (after the expiration of any applicable notice and/or cure period), or for the purpose of complying with Legal Requirements or other directions of governmental authorities.
Landlord shall repair, at Landlord’s expense, any actual damage caused by Landlord during the course of such work and/or entry into the Premises, and shall restore the Premises as nearly as reasonably practicable to the condition existing prior
to such installation but in no event shall Landlord be obligated to employ overtime labor or to incur any extraordinary expenses in connection therewith. Tenant shall permit Landlord to erect, use and

  
 29 

 
maintain ducts, pipes and conduits in and through the Premises and the Licensed Space and to erect new pipes and conduits therein, provided, however, that (i) to the extent reasonably
possible (without the expenditure of any extraordinary expense), any such ducts, pipes or conduits installed in or through any portion of the Premises where there is no drop ceiling shall either be concealed behind, beneath or within partitioning,
columns, ceilings or floors located in the Premises, or completely furred at points immediately adjacent to partitioning, columns, ceilings or floors located in the Premises, (ii) the installation of any such pipes, ducts, or conduits, when
completed, shall not reduce the usable area of the Premises beyond a de minimis amount and (iii) Landlord shall repair any damage caused by Landlord to the Premises as a result of any such installations. Landlord may, during the progress
of any work in the Premises and the Licensed Space, take all necessary materials and equipment into the Premises and the Licensed Space, as applicable, without the same constituting an eviction nor shall Tenant be entitled to any abatement of rent
while such work is in progress nor to any damages by reason of loss or interruption of business or otherwise. Throughout the term hereof but subject to the provisions of Section 15.2, Landlord shall have the right to enter the Premises
at reasonable hours, upon reasonable prior notice to Tenant, for the purpose of showing the same to (i) prospective purchasers or mortgagees of the Building or (ii) to any other persons to the extent such showing relates to sustainable
design efforts, improvements, and/or initiatives at the Campus. During the last year of the Term, Landlord shall have the right to enter the Premises at reasonable hours, upon reasonable prior notice to Tenant, for the purpose of showing the same to
prospective tenants. If Tenant is not present to open and permit an entry into the Premises or the Licensed Space, Landlord or Landlord’s agents may enter the same whenever such entry may be necessary or permissible by master key or forcibly
(in the event of any emergency) and provided reasonable care is exercised to safeguard Tenant’s property and such entry shall not render Landlord or its agents liable therefor, nor in any event shall the obligations of Tenant hereunder be
affected except that Landlord shall promptly repair any damage caused by Landlord as a result thereof. Landlord shall have the right at any time (including, without limitation, in connection with any repairs, replacements and improvements that
Landlord may perform pursuant to the terms of Section 8.1(a) hereof), without the same constituting an eviction and without incurring liability to Tenant therefor to change the arrangement, design and/or location of public entrances,
storefronts, passageways, doors, doorways, corridors, elevators, stairs, toilets, or other public parts of any Building and to change the name, number or designation by which a Building may be known, provided that any such change does not diminish
Tenant’s means of access to the Premises beyond a de minimis extent. In connection with any access under this Article 15, Landlord agrees to use commercially reasonable efforts to minimize interference with Tenant’s use and
occupancy of the Premises; provided that in no event shall Landlord be required to utilize overtime or premium pay labor or incur any extraordinary costs in connection therewith. 

15.2 Tenant shall have the right to reasonably designate, by written notice to Landlord, certain areas of the Premises (including any area
containing a safe, financial information or information relating to Tenant’s product research and development) as secure areas (each, a “Secure Area”). Tenant shall have the right to have a representative accompany Landlord
(and persons authorized by Landlord) during any entry into the Secure Area (except in an emergency), which representative Tenant agrees to make available upon Landlord’s reasonable request. Landlord agrees to keep all information obtained by it
during any entry into a Secure Area confidential and shall use commercially reasonable efforts to comply and cause its employees 

  
 30 

 
and contractors to comply with any controls instituted by Tenant to prevent the disclosure of confidential information contained in any Secure Area. In furtherance of the foregoing, upon
Tenant’s request, Landlord shall and shall cause any of its contractors seeking to access any portion of the Secure Area to execute and deliver a confidentiality agreement in form and substance reasonable acceptable to Tenant and the party
intending to access such Secure Area. 
 ARTICLE 16  

VAULT, VAULT SPACE, AREA 

No vaults, vault space or area, whether or not enclosed or covered, not within the property line of the Buildings is leased hereunder,
anything contained in or indicated on any sketch, blue print or plan or anything contained elsewhere in this Lease to the contrary notwithstanding. Landlord makes no representation as to the location of the property line of the Buildings. All vaults
and vault space and all such areas not within the property line of the Buildings, which Tenant may be permitted to use and/or occupy, is to be used and/or occupied under a revocable license, and if any such license be revoked, or if the amount of
such space or area be diminished or required by any federal, state or municipal authority or public utility, Landlord shall not be subject to any liability nor shall Tenant be entitled to any compensation or diminution or abatement of rent, nor
shall such revocation, diminution or requisition be deemed constructive or actual eviction. Any tax, fee or charge of municipal authorities for such vault or area shall be paid by Tenant. 

ARTICLE 17  
 BANKRUPTCY

 17.1 Neither Tenant’s interest in this Lease, nor any estate hereby created in Tenant nor any interest herein or therein, shall
pass to any debtor-in-possession, trustee, or receiver or assignee for the benefit of creditors or otherwise by operation of law except as may specifically be provided pursuant to the provisions of the Bankruptcy Code, 11 U.S.C.§ 101 et seq.
(the “Bankruptcy Code”). If this Lease is assigned to any person or entity pursuant to the Bankruptcy Code, any and all consideration payable or otherwise to be delivered in connection with such assignment shall be paid or delivered
to Landlord, shall be and remain the exclusive property of Landlord and shall not constitute property of Tenant or of the estate of Tenant within the meaning of the Bankruptcy Code. Any and all monies and other consideration constituting
Landlord’s property under the preceding sentence not paid or delivered to Landlord shall be held in trust for the benefit of Landlord and be promptly paid to or turned over to Landlord. 

17.2 Anything elsewhere in this Lease to the contrary notwithstanding, this Lease may be cancelled by Landlord by the sending of a notice to
Tenant within a reasonable time after the happening of any one or more of the following events: (i) the commencement of a case in bankruptcy or under the laws of any state naming Tenant as the debtor; which case shall not have been dismissed
within ninety (90) days after the institution thereof, or (ii) the making by Tenant of an assignment or any other arrangement for the benefit of creditors under any state statute. Neither Tenant nor any person claiming through or under
Tenant, or by reason of any statute or order of court, shall thereafter be entitled to possession of the Premises but shall forthwith quit 

  
 31 

 
and surrender the Premises. If this Lease shall be assigned in accordance with its terms, the provisions of this Article 17 shall be applicable only to the party then owning Tenant’s
interest in this Lease. 
 17.3 It is stipulated and agreed that in the event of the termination of this Lease pursuant to
Section 17.2 hereof, Landlord shall forthwith, notwithstanding any other provisions of this Lease to the contrary, be entitled to recover from Tenant as and for liquidated damages an amount equal to the difference between the rent
reserved hereunder for the unexpired portion of the term demised for the same period. In the computation of such damages the difference between any installment of rent becoming due hereunder after the date of termination and the fair and reasonable
rental value of the Premises for the period for which such installment was payable shall be discounted to the date of termination at the rate of four percent (4%) per annum. If such premises or any part thereof shall be re-let by Landlord for
the unexpired term of this Lease, or any part thereof, before presentation of proof of such liquidated damages to any court, commission or tribunal, the amount of rent reserved upon such re-letting shall be deemed to be the fair and reasonable
rental value for the part or the whole of the Premises so re-let during the term of the re-letting. Nothing herein contained shall limit or prejudice the right of Landlord to prove for and obtain as liquidated damages by reason of such termination,
an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, such damages are to be proved, whether or not such amount be greater, equal to, or less than the amount of the
difference referred to above. 
 ARTICLE 18  

DEFAULT 
 18.1 If Tenant
defaults in fulfilling any of the covenants of this Lease other than the covenants for the payment of Minimum Rent or additional rent; or if the Premises are abandoned; or if any execution or attachment shall be issued against Tenant or any of
Tenant’s property whereupon the Premises shall be taken or occupied by someone other than Tenant without Landlord’s express consent; then, in any one or more of such events, upon Landlord serving a thirty (30) days’ notice upon
Tenant specifying the nature of said default and upon the expiration of said thirty (30) days, if Tenant shall have failed to comply with or remedy such default, or if the said default or omission complained of shall be of a nature that the
same cannot be completely cured or remedied within said thirty (30) day period, and if Tenant shall not have diligently commenced curing such default within such applicable period, and shall not thereafter, to the extent permitted, with
reasonable diligence and in good faith proceed to remedy or cure such default, then Landlord may serve a three (3) business days’ notice of cancellation of this Lease upon Tenant and upon the expiration of said three (3) business
days, this Lease and the term hereunder shall end and expire as fully and completely as if the expiration of such three (3) business day period were the day herein definitely fixed for the end and expiration of this Lease and the term thereof
and Tenant shall then quit and surrender the Premises to Landlord but Tenant shall remain liable as hereinafter provided. 
 18.2 If the
notice provided for in Section 18.1 hereof shall have been given, and the term shall expire as aforesaid; or if Tenant shall make default in the payment of the Minimum Rent reserved herein or any item of additional rent herein mentioned
or any part of either or in 

  
 32 

 
making any other payment herein required and such default shall not be cured within five (5) days after the delivery of notice from Landlord to Tenant with respect thereto; then and in any
of such events Landlord may without further notice, re-enter the Premises either by force (but only to the extent permitted under applicable Legal Requirements) or otherwise, and dispossess Tenant by summary proceedings or otherwise, and the legal
representative of Tenant or other occupant of demised premises and remove their effects and hold the Premises as if this Lease had not been made, and Tenant hereby waives the service of notice of intention to re-enter or to institute legal
proceedings to that end. If Tenant shall make default hereunder prior to the date fixed as the commencement of any renewal or extension of this Lease, Landlord may cancel and terminate such renewal or extension agreement by notice. The words
“re-enter” and “re-entry” as used in this Lease are not restricted to their technical legal meaning. 
 ARTICLE 19 

 REMEDIES OF LANDLORD AND WAIVER OF REDEMPTION 

19.1 In case of any such default beyond the expiration of any applicable notice and/or cure period, re-entry, expiration and/or dispossess by
summary proceedings or otherwise, (i) the rent shall become due thereupon and be paid up to the time of such re-entry, dispossess and/or expiration, together with such expenses as Landlord may incur for attorneys’ fees and disbursements,
brokerage, and/or putting the Premises in good order, or for preparing the same for re-rental; (ii) Landlord may (but without any obligation to do so) re-let the Premises or any part or parts thereof, either in the name of Landlord or
otherwise, for a term or terms, which may at Landlord’s option be less than or exceed the period which would otherwise have constituted the balance of the term of this Lease and may grant concessions or free rent or charge a higher rental than
that in this Lease, and/or (iii) Tenant or the legal representatives of Tenant shall also pay Landlord as liquidated damages for the failure of Tenant to observe and perform said Tenant’s covenants herein contained, any deficiency between
the rent hereby reserved and/or covenanted to be paid and the net amount, if any, of the rents collected on account of the lease or leases of the Premises for each month of the period which would otherwise have constituted the balance of the Term of
this Lease. The failure of Landlord to re-let the Premises or any part or parts thereof shall not release or affect Tenant’s liability for damages. In computing such liquidated damages there shall be added to the said deficiency such expenses
as Landlord may incur in connection with re-letting, such as legal expenses, attorneys’ fees and disbursements, brokerage, advertising and for keeping the Premises in good order or for preparing the same for re-letting. Any such liquidated
damages shall be paid in monthly installments by Tenant on the rent day specified in this Lease and any suit brought to collect the amount of the deficiency for any month shall not prejudice in any way the rights of Landlord to collect the
deficiency for any subsequent month by a similar proceeding. Landlord, in putting the Premises in good order or preparing the same for re-rental may, at Landlord’s option, make such alterations, repairs, replacements, and/or decorations in the
Premises as Landlord, in Landlord’s sole judgment, considers advisable and necessary for the purpose of re-letting the Premises, and the making of such alterations, repairs, replacements, and/or decorations shall not operate or be construed to
release Tenant from liability hereunder as aforesaid. Landlord shall in no event be liable in any way whatsoever for failure to re-let the Premises, or in the event that the Premises are re-let, for failure to collect the rent thereof under such
re-letting, and in no event shall Tenant be entitled to receive any excess, if any, of such net rent collected over the sums payable by Tenant. Landlord 

  
 33 

 
shall have the right of injunction and the right to invoke any remedy allowed at law or in equity as if re-entry, summary proceedings and other remedies were not herein provided for. Mention in
this Lease of any particular remedy shall not preclude Landlord from any other remedy in law or in equity. Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant being
evicted or dispossessed for any cause, or in the event of Landlord obtaining possession of demised premises, by reason of the violation by Tenant of any of the covenants and conditions of this Lease, or otherwise. 

19.2 In the event this Lease is terminated pursuant to the provisions of Article 18 herein, then in addition to the remedies Landlord
may have pursuant to Section 19.1 herein, Landlord may elect, at its option, to recover from Tenant, all damages it may incur by reason of such breach, including the cost of recovering the Premises and reasonable attorneys’ fees and
expenses and shall be entitled to recover as and for liquidated damages, and not as a penalty, an amount equal to the difference between (1) the Minimum Rent, Additional Rent and charges equivalent to rent payable hereunder for the remainder of
the stated Term and (2) the reasonable rental value of the Premises for the remainder of the stated term, both discounted at the rate of four (4%) percent per annum to present worth, all of which shall be immediately due and payable by
Tenant. In determining the rental value of the Premises for such period, the rental realized by any reletting, if such reletting be accomplished by Landlord within a reasonable period of time after the termination of this Lease, shall be deemed
prima facie to be the rental value. Landlord shall not be liable in any way whatsoever for its failure or refusal to relet the Premises or any part thereof, or if the Premises are so relet, for its failure to collect the rent under
such reletting, and no refusal or failure to relet or failure to collect rent shall affect Tenant’s liability for damages or otherwise hereunder. Nothing herein contained shall limit or prejudice the right of Landlord to prove and obtain as
liquidated damages by reason of such termination an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, such damages are to be proved, whether or not such amount be
greater, equal to, or less than the amounts referred to herein.

Tenant shall default in the observance or performance of any term or covenant on Tenant’s part to be observed or performed under or by virtue of any of the terms or provisions in any Article of this Lease and such default shall continue after
the expiration of any applicable notice and/or cure period, then, unless otherwise provided elsewhere in this Lease, Landlord may immediately or at any time thereafter and without notice perform the obligation of Tenant thereunder, and if Landlord,
in connection therewith or in connection with any default by Tenant in the covenant to pay rent hereunder, makes any expenditures or incurs any obligations for the payment of money, including but not limited to reasonable attorneys’ fees and
disbursements, in instituting, prosecuting or defending any action or proceeding, such sums so paid or obligations incurred with interest and costs shall be deemed to be additional rent hereunder and shall be paid by Tenant to Landlord within ten
(10) days of rendition of any bill or statement to Tenant therefore, and if the Term shall have expired at the time of making of such expenditures or incurring of such obligations, such sums shall be recoverable by Landlord as damages.

 ARTICLE 21  

NO REPRESENTATIONS BY LANDLORD 

Neither Landlord nor Landlord’s agents have made any representations or promises with respect to the physical condition of the Building,
the Land, the Premises or the Licensed Space, the rents, leases, expenses of operation or any other matter or thing affecting or related to the Premises or the Licensed Space except as herein expressly set forth and no rights, easements or licenses
are acquired by Tenant by implication or otherwise except as expressly set forth in the provisions of this Lease. Tenant has inspected the Buildings, the Premises and the Licensed Space and is thoroughly acquainted with their condition, and agrees
to take the same “as is”. All understandings and agreements heretofore made between the parties hereto are merged in this Lease, which alone fully and completely expresses the agreement between Landlord and Tenant and any executory
agreement hereafter made shall be ineffective to change, modify, discharge or effect an abandonment of it in whole or in part, unless such executory agreement is in writing and signed by the party against whom enforcement of the change,
modification, discharge or abandonment is sought. 
 ARTICLE 22  

END OF TERM 
 Upon the
expiration or other termination of the term of this Lease, Tenant shall quit and surrender to Landlord the Premises, broom clean, vacant, in good order and condition, ordinary wear excepted, together with the Premises FF&E in good order and
condition subject to ordinary wear, and Tenant shall perform any restoration obligation imposed upon Tenant pursuant to the terms hereof, including, without limitation, Article 7 and Article 36 and remove all of its personal property.
Tenant’s obligation to observe or perform this covenant shall survive the expiration or other termination of this Lease. If the last day of the term of this Lease or any renewal thereof, falls on Sunday, this Lease shall expire at noon on the
preceding Saturday unless it be a legal holiday in which case it shall expire on the preceding business day. 
 ARTICLE 23  

QUIET ENJOYMENT 
 Landlord
covenants and agrees with Tenant that upon Tenant paying the Minimum Rent and additional rent and observing and performing all the terms, covenants and conditions, on Tenant’s part to be observed and performed, Tenant may peaceably and quietly
enjoy the Premises hereby demised, subject, nevertheless, to the terms and conditions of this Lease including, but not limited to, Article 29 hereof and to the ground leases, underlying leases and mortgages hereinbefore mentioned. 

  
 35 

 ARTICLE 24  

NO WAIVER 
 The failure of
Landlord or Tenant to seek redress for violation of, or to insist upon the strict performance of any covenant or condition of this Lease shall not prevent a subsequent act which would have originally constituted a violation from having all the force
and effect of an original violation. The receipt by Landlord, or the payment by Tenant, of rent with knowledge of the breach of any covenant of this Lease shall not be deemed a waiver of such breach and no provision of this Lease shall be deemed to
have been waived by Landlord or Tenant unless such waiver be in writing signed by the party to be charged with such waiver. No payment by Tenant or receipt by Landlord of a lesser amount than the monthly rent herein stipulated shall be deemed to be
other than on account of the earliest stipulated rent, nor shall any endorsement or statement of any check or any letter accompanying any check or payment as rent be deemed an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord’s right to recover the balance of such rent or pursue any other remedy in this Lease provided. No act or thing done by Landlord or Landlord’s agents during the term hereby demised shall be deemed an acceptance
of a surrender of the Premises and no agreement to accept such surrender shall be valid unless in writing signed by Landlord. No employee of Landlord or Landlord’s agent shall have any power to accept the keys of the Premises prior to the
termination of this Lease and the delivery of keys to any such agent or employee shall not operate as a termination of this Lease or a surrender of the Premises. 

ARTICLE 25  
 DISPUTE
RESOLUTION; WAIVER OF TRIAL BY JURY 
 25.1 Any dispute, controversy or claim arising out of or relating to this Lease (a
“Dispute”), shall initially be referred to the Transition Committee (as defined in the Separation and Distribution Agreement) for resolution. If the Transition Committee is unable to resolve such Dispute within thirty
(30) days, then either party may provide written notice thereof to the other party (the “Initial Notice”), and the parties shall thereafter attempt in good faith to negotiate a resolution of the Dispute. The negotiations shall
be conducted by executives who hold, at a minimum, the title of vice president and who have authority to settle the Dispute. All such negotiations shall be confidential and shall be treated as compromise and settlement negotiations for purposes of
applicable rules of evidence. 
 25.2 In the event that a Dispute has not been resolved within sixty (60) days after receipt by a party
of an Initial Notice, or within such longer period as the Parties may agree to in writing, then each party hereby agrees and consents to be subject to the jurisdiction of the Court of Common Pleas of the Commonwealth of Pennsylvania in and for
Lancaster County, or if the Court of Common Pleas lacks jurisdiction over such dispute, in any state or federal court having jurisdiction over the matter situated in Lancaster County, Pennsylvania, to resolve any such unresolved Dispute in any suit,
action or proceeding seeking to enforce any provision of, or based on any other matter arising out of or in connection with, this Lease. Each of the parties hereto irrevocably and unconditionally waives any objection to the laying of venue of any
action, suit or proceeding arising out of this Agreement or the transactions contemplated hereby in the 

  
 36 

 
Court of Common Pleas of the Commonwealth of Pennsylvania in and for Lancaster County, or if the Court of Common Pleas lacks jurisdiction over such dispute, in any state or federal court having
jurisdiction over the matter situated in Lancaster County, Pennsylvania, and hereby further irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such action, suit or proceeding brought in any such court
has been brought in an inconvenient forum. Notwithstanding this Article 25, Landlord may seek injunctive relief from the Court of Common Pleas of the Commonwealth of Pennsylvania in and for Lancaster County (or if the Court of Common Pleas
lacks jurisdiction over such dispute, in any state or federal court having jurisdiction over the matter situated in Lancaster County, Pennsylvania) at any time after a breach by Tenant of any of its obligations under Section 2.2 of this
Lease. 
 25.3 It is mutually agreed by and between Landlord and Tenant that the respective parties hereto shall and they hereby do waive
trial by jury in any action, proceeding (except for personal injury or property damage) on any matters whatsoever arising out of or in any way connected with this Lease, the relationship of Landlord and Tenant, Tenant’s use of or occupancy of
the Premises or the Licensed Space, and any emergency statutory or any other statutory remedy. It is further mutually agreed that in the event Landlord commences any summary proceeding for possession of the Premises, Tenant will not interpose any
counterclaim of whatever nature or description in any such proceeding (except such compulsory or mandatory counterclaims that would be waived if not raised in such proceeding). 

ARTICLE 26  
 INABILITY
TO PERFORM 
 This Lease and the obligation of Tenant to pay rent hereunder and perform all of the other covenants and agreements
hereunder on part of Tenant to be performed shall in no way be affected, impaired or excused because Landlord is unable to perform any of its obligations under this Lease or to supply or is delayed in supplying any service expressly or impliedly to
be supplied or is unable to make, or is delayed in making any repair, additions, alterations or decorations or is unable to supply or is delayed from so doing by reason of strike or labor troubles or any cause whatsoever including, but not limited
to, government preemption in connection with a national emergency or by reason of any rule, order or regulation of any department or subdivision thereof of any government agency or by reason of the conditions of supply and demand which have been or
are affected by war or other emergency.

CAPTIONS 
 The captions
are inserted only as a matter of convenience and for reference and in no way define, limit or describe the scope of this Lease nor the intent of any provision hereof. 

  
 37 

 ARTICLE 28  

ADJACENT EXCAVATION – SHORING 

If an excavation shall be made upon land adjacent to the Premises, or shall be authorized to be made, Tenant shall afford to the person
causing or authorized to cause such excavation, license to enter upon the Premises for the purpose of doing such work as said person shall deem necessary to preserve the wall or the Buildings from injury or damage and to support the same by proper
foundations without any claim for damages or indemnity against Landlord, or diminution or abatement of rent. 
 ARTICLE 29  

COMPLIANCE 
 Tenant and
Tenant’s servants, employees, agents, visitors, and licensees shall use the Premises, the Licensed Space and the Common Areas in a manner that is generally consistent with Landlord’s past practices (including Landlord’s past practices
with respect to environmental, health and safety practices) unless otherwise agreed to by Landlord in writing. Nothing in this Lease contained shall be construed to impose upon Landlord any duty or obligation to enforce the terms, covenants or
conditions in any other lease, as against any other tenant and Landlord shall not be liable to Tenant for violation of the same by any other tenant, its servants, employees, agents, visitors or licensees. 

ARTICLE 30  
 SUCCESSORS
AND ASSIGNS 
 The covenants, conditions and agreements contained in this Lease shall bind and inure to the benefit of Landlord and
Tenant and their respective heirs, distributees, executors, administrators, successors, and except as otherwise expressly provided in this Lease, their assigns. 

ARTICLE 31  
 INSURANCE

 31.1 Tenant covenants and agrees to obtain on or before the Commencement Date and to keep in force during the Term (i) “all
risk” property insurance covering all present and future property of Tenant, furniture and/or furnishings and any Alterations installed by or on behalf of Tenant, to a limit of not less than the full replacement value thereof, such insurance to
include a replacement cost endorsement, and (ii) a commercial general liability insurance policy protecting against any liability whatsoever, occasioned by any occurrence on or about the Premises or any appurtenances thereto with limits of
liability thereunder of not less than the amount of $5,000,000 per occurrence for bodily or personal injury (including death) and in the amount of $1,000,000 in respect of property damage. The insurance policies required hereunder shall be written
by insurance companies authorized to do business in the Commonwealth of Pennsylvania 

  
 38 

 
and with AM Best Rating of A- or better and shall be in such limits as Landlord may reasonably require. All insurance required hereunder shall name Tenant as the insured and shall also name as
additional insureds Landlord and such other parties as Landlord shall reasonably designate as additional insureds. The insurance required hereby may be carried under a blanket policy covering the Premises and other locations of Tenant, if any. Prior
to the time such insurance is first required to be carried by Tenant and thereafter, no later than ten (10) days of renewal thereof, Tenant agrees to deliver to Landlord either a duplicate original of the aforesaid policies or a certificate
evidencing such insurance, except that the property insurance referred to above, however, must be evidenced by delivery by Tenant to Landlord of the ACORD Form 27, Evidence of Property Insurance Form or its equivalent. Said certificates (including
ACORD Form 27 or its equivalent) shall contain an endorsement that such insurance may not be cancelled except upon at least thirty (30) days’ prior notice to all insureds thereunder. Tenant’s failure to provide and keep in force
the aforementioned insurance shall be regarded as a material default hereunder entitling Landlord to exercise any or all of the remedies as provided in this Lease in the event of Tenant’s default. 

31.2 Landlord at its expense shall maintain throughout the term (with customary deductibles) (a) all-risk insurance against loss or
damage by fire or other casualty, in an amount equal to one hundred percent (100%) of the replacement value of the Buildings and (b) a policy of commercial general liability insurance in an amount of $5,000,000 per occurrence for bodily or
personal injury (including death). 
 ARTICLE 32 

BROKERAGE 
 Tenant and
Landlord covenant, represent and warrant that neither party has had any dealings or communications with any broker or agent in connection with the consummation of this Lease, and Tenant and Landlord covenant and agree to hold harmless and indemnify
the other party and its officers, directors, employees and members from and against any and all cost, expense (including reasonable attorneys’ fees and disbursements) and liability arising out of any inaccuracy or alleged inaccuracy of the
above representation. 
 ARTICLE 33 

ESTOPPEL CERTIFICATE 

33.1 Tenant shall, at any time and from time to time, as requested by Landlord, upon fifteen (15) days’ prior notice, execute and
deliver to Landlord a statement setting forth the Commencement Date, the Expiration Date, the Minimum Rent and Additional Rent and certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the
same is in full force as modified and stating the modifications), the dates to which the Minimum Rent and Additional Rent have been paid, whether or not, to the best knowledge of Tenant, Landlord is in default in performance of any of its
obligations under this Lease, and, if so, specifying each such default of which Tenant may have knowledge, and whether there exist any offsets or defenses against enforcement of any of the terms of this Lease upon the part of Tenant to be performed,
and, if so, specifying the same, and any other information Landlord may reasonably request, it being intended that any such statement delivered pursuant hereto may be relied upon by others with whom Landlord may be dealing. 

  
 39 

 33.2 Landlord shall, at any time and from time to time, as reasonably requested by Tenant, upon
ten (10) days’ prior notice, execute and deliver to Tenant a statement certifying that this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force as modified and stating the
modifications), the dates to which the Minimum Rent and Additional Rent have been paid, the amount of Tenant’s security deposit then being held by Landlord, whether or not, to the best knowledge of Landlord, Tenant is in default in performance
of any of its obligations under this Lease, and, if so, specifying each such default of which Landlord may have knowledge. 
 ARTICLE 34 

 HOLDING OVER 

34.1 Tenant acknowledges that possession of the entire Premises must be surrendered to Landlord at the expiration or sooner termination of the
term hereof. The parties recognize and agree that the damage to Landlord resulting from any failure by Tenant timely to surrender possession of the entire Premises as aforesaid will be substantial, will exceed the amount of annual Minimum Rent and
additional rent theretofore payable hereunder, and will be impossible to measure accurately. Tenant therefore agrees that if possession of the entire Premises is not surrendered to Landlord upon the expiration or sooner termination of the term of
this Lease, then notwithstanding anything to the contrary contained in this Lease, Tenant shall pay to Landlord for each month and for each portion of any month during which Tenant holds over in the Premises after the expiration or sooner
termination of the term hereof, for use and occupancy, Minimum Rent at (i) 150% of the final monthly rate of the then current Term specified in Article 3 for the first thirty (30) days that Tenant thus remains in possession,
(ii) 200% thereafter, together with all Additional Rent payable hereunder (and Landlord may accept such amounts without in any way waiving its rights to require Tenant to vacate the Premises) and, in addition thereto, if such holdover shall
continue for more than five (5) business days, Tenant shall pay Landlord for all damages sustained by reason of Tenant’s retention of possession beyond five (5) business days after the expiration or earlier termination of this Lease,
but in no event shall Tenant be liable to Landlord for any indirect, special, punitive or consequential damages. 
 34.2 If Tenant remains
in possession of the Premises, or any part thereof, after the expiration or earlier termination of the term of this Lease, such holding over shall, at the election of Landlord expressed in a notice to Tenant and not otherwise, constitute a tenancy
from month-to-month. The provisions of this Article 34 do not imply any right in Tenant to remain in the Premises after the termination of this Lease, or exclude Landlord’s right of re-entry or any other right or remedy hereunder or at
law which Landlord may have against a holdover tenant. 

  
 40

 ARTICLE 36  

EXISTING FF&E 
 All of
the furniture, fixtures and equipment located in the Premises and the Licensed Space as of the Commencement Date (collectively, the “Premises FF&E”) shall remain the property of Landlord. For the avoidance of doubt, the
equipment located in the Premises and the Licensed Space and identified on Exhibit E attached hereto (the “Excluded FF&E,” and together with the Premises FF&E, collectively, the “Existing FF&E”)
is the sole property of the Tenant and does not constitute part of the property being leased to Tenant hereunder; it being agreed and acknowledged that all of Landlord’s right, title and interest in and to the Excluded FF&E have been
conveyed to Tenant pursuant to and subject to the terms of the Separation and Distribution Agreement. Notwithstanding the foregoing, the Premises FF&E shall not include any testing, manufacturing, laboratory, operating or other equipment
currently use primarily by Tenant in connection with the AFI Business (as defined in the Separation and Distribution Agreement). Landlord makes no representation or warranty with respect to the Existing FF&E. Landlord shall have no obligation or
liability to repair, replace or maintain the Existing FF&E. Tenant, at Tenant’s sole cost and expense, shall maintain the Existing FF&E in good working order and condition subject to reasonable wear and tear and shall have the right to
replace the Existing FF&E or otherwise install such other furniture, fixtures and equipment in the Premises or the Licensed Space in accordance with the terms set forth in Article 7 and Article 40, as applicable. At or prior to the
expiration or earlier termination of this Lease, Tenant shall remove all Excluded FF&E from the Premises and shall restore, at Tenant’s sole cost and expense, the Premises in a manner reasonably satisfactory to Landlord. All Excluded
FF&E remaining in the Premises following the expiration or earlier termination of this Lease shall be deemed abandoned and may, at the election of Landlord, either be retained as Landlord’s property or may be removed from the Premises by
Landlord at Tenant’s expense. 
 ARTICLE 37  

CERTAIN RIGHTS RESERVED TO LANDLORD 

37.1 Landlord reserves the following rights: 

(a) Subject to the terms of Article 39, to install, affix and maintain all signs, awnings, scaffolding, sidewalk bridges and canopies

Landlord shall have no liability to Tenant, 

  
 42 

 
nor shall Tenant be entitled to terminate this Lease, to claim an actual or constructive eviction in whole or in part, or be entitled to any abatement or diminution of rent payable by Tenant
under this Lease or to any relief from any of its obligations under this Lease if by reason of strike or labor trouble or any other similar cause beyond the reasonable control of Landlord (including, but not limited to, acts of war, emergency,
casualty, terrorism, bioterrorism, or governmental preemption in connection with a national emergency) (A) there is (i) a lack of access to any Building, the Premises, the Licensed Space or the Common Areas (which shall include without
limitation the lack of access to the Buildings, the Premises, the Licensed Space or the Common Areas when it or they are structurally sound but inaccessible due to evacuation of the surrounding area or damage to nearby structures or public areas);
(ii) reduced air quality or other contaminants in the Buildings, the Licensed Space or the Common Areas that would adversely affect the Building or its occupants, including without limitation the presence of biological or other airborne agents
within the Building, the Licensed Space or the Premises; (iii) disruption of mail and deliveries to the Building or the Premises; (iv) disruption of telephone and/or other communications services to the Buildings, the Premises or the

 ARTICLE 38 
 HAZARDOUS
MATERIALS 
 38.1 Tenant hereby represents, warrants and covenants that it shall not install, cause or permit any Hazardous Materials to
be placed or stored in or about the Premises or the Licensed Space in violation of any applicable environmental or other Legal Requirements; provided, that nothing herein shall prevent Tenant’s use of such reasonable amounts of Hazardous
Materials customarily used in the ordinary course of operation of Tenant’s business in the Premises in accordance with this Lease if such use is for such ordinary course of such operation or in connection with Alterations provided that, in
either case, such use is in accordance with all Legal Requirements applicable to the Building or the Premises or any part thereof, and Tenant’s observance of all provisions of this Lease. For the avoidance of doubt, Tenant shall promptly notify
the Landlord’s Director of Facilities if: (i) Tenant intends to change how it currently stores any Hazardous Material such that additional modifications or special treatment (including, without limitation, the installation of sprinklers or
secondary containment) will be required at that portion of the Premises or the Licensed Space at which the Hazardous Material is present, (ii) Tenant intends to change any laboratory or pilot line equipment such that an environmental permit
review by the Pennsylvania Department of Environmental Protection will be reasonably required, or (iii) there are any new instances of generating or storing any Hazardous Material; provided, however, that the foregoing shall not apply to small
amounts of Hazardous Materials customarily used by Tenant in a laboratory and in accordance with all Legal Requirements applicable to the Building or the Premises or any part thereof. Tenant shall indemnify and hold Landlord harmless from and
against any claims, demands, losses, liabilities, penalties and damages arising out of, or in any way connected with the installation, placement, storage or release of Hazardous Materials used or installed by Tenant, Tenant’s employees,
contractors or agents upon the Premises or the Licensed Space in violation of the terms of this Lease. If Tenant, or its employees, contractors or agents install, use, store or place Hazardous Materials in

  
 43 

 
the Premises or the Licensed Space, Tenant shall be obligated to remove and dispose of said Hazardous Materials in compliance with all Legal Requirements. This covenant shall survive the
expiration or earlier termination of this Lease. 
 38.2 As used herein, the term “Hazardous Materials” shall be any
petroleum product, asbestos product, or any other material, substance or waste that is now, or hereafter during the Term, recognized as being hazardous or dangerous to health or the environment by any federal, state or local agency having
jurisdiction over the Building (including, without limitation, any material, substance or waste that has been classified as hazardous under 29 CFR § 1910.1200). 

ARTICLE 39 
 SIGNAGE 

The parties acknowledge that there is limited space available in the Campus for the installation of signage. The parties will cooperate in
good faith to develop a fair and equitable approach to signage (including, without limitation, the location, size, design, materials and installation of such signage) that takes into account the needs of Landlord, Tenant and any other existing and
future tenants at the Campus, the space occupied by each of the respective parties, the expectations of the surrounding community, and applicable Legal Requirements. Tenant shall, at its sole cost and expense, remove any signage installed by or on
behalf of Tenant on or before the expiration or earlier termination of this Lease and shall repair any damage caused by said removal.

Landlord’s sole discretion. 
 (b) Notwithstanding anything to the contrary contained herein, the term of the license
granted herein shall commence on the Commencement Date and shall expire on the earlier of (A) (i) with respect to the Building 5A Licensed Space and the Building 4 Licensed Space, the date that is one (1) year from the date that
Landlord delivers written notice to Tenant of its desire to use, lease or otherwise occupy all or any portion of the Building 5A Licensed Space or the Building 4 Licensed Space, as applicable (the “Equipment License Expiration
Date”) and (ii) with respect to the Building 701 Licensed Space, the earlier of (x) date that is ninety (90) days from the date 

  
 44 

 
that Landlord delivers written notice (the “Termination Notice”) to Tenant of its desire to use, lease or otherwise occupy all or any portion of the Building 701 Licensed Space
or (y) the Initial Expiration Date (the “701 License Expiration Date,” and together with the Equipment License Expiration Date, the “Building Licensed Space Expiration Date”) or (B) that date the term of
the Lease shall cease and terminate as herein provided. 
 (c) In the event Landlord delivers a Termination Notice to Tenant
which requires Tenant to vacate the Building 701 Licensed Space prior to the Initial Expiration Date and Tenant is not then in default beyond the expiration of any applicable notice and/or cure period, Landlord shall upgrade (the “Building
123 Upgrade”) the portion of the Premises located within Buildings 1, 2 and 3 with such furniture, fixtures and equipment as are necessary to accommodate the relocation of Tenant’s employees from the Building 701 Licensed Space to
Buildings 1, 2 and 3, provided that the costs in connection with such Building 123 Upgrade shall not exceed $600,000 in the aggregate. The parties hereby agree and acknowledge that the costs incurred by Landlord in connection with the Building 123
Upgrade (which shall not exceed $600,000 in the aggregate) shall be treated as Operating Expenses pursuant to and in accordance with Section 5.3(a)(iv). 

(d) Tenant shall remove Tenant’s Property within the applicable Building Licensed Space upon the applicable Building
Licensed Space Expiration Date or earlier termination of the Lease and repair any damage to the Building Licensed Space or other portions of the applicable building caused by the removal thereof, all at Tenant’s sole cost and expense. In the
event Tenant’s Property remains in the Building Licensed Space following the applicable Building Licensed Space Expiration Date or earlier termination of the Lease, the same shall be deemed abandoned and may, at the election of Landlord, either
be retained as Landlord’s property or may be removed from the applicable Licensed Space by Landlord at Tenant’s expense. 
 40.2
Data Center Licensed Space 
 (a) Landlord hereby grants to Tenant an exclusive license, subject to and in accordance with
the provisions of this Section 40.2 and upon and subject to all of the other terms of this Lease, to use the space designated on Exhibit G attached hereto (the “Data Center Licensed Space”; and together with the
Building Licensed Space, the “Licensed Space”) solely for equipment storage, data center and telecommunication uses that comply with the terms hereof. 

(b) Tenant hereby agrees and acknowledges that the individuals set forth on Schedule 40.2(b) attached hereto (the
“Designated Tenant Representatives”) are the sole representatives of Tenant that are permitted to access the Data Center Licensed Space at any time, provided that Tenant shall have the right to update the list of Designated Tenant
Representatives from time to time by delivering written notice thereof to Landlord, but in no event shall the total number of Designated Tenant Representatives exceed twenty (20) persons at any one time. Landlord shall have the right to have a
representative accompany any of the Designated Tenant Representatives during any entry into the Data Center Licensed Space. Tenant shall cause the Designated Tenant Representatives to 

  
 45 

 
keep all information obtained during any entry into the Data Center Licensed Space confidential and shall comply with and cause the Designated Tenant Representatives to comply with any controls
instituted by Landlord to prevent the disclosure of confidential information contained in the Data Center Licensed Space. In furtherance of the foregoing, upon Landlord’s request, each of Tenant and the Designated Tenant Representatives shall
execute and deliver a confidentiality agreement in form and substance reasonably acceptable to Landlord and Tenant. 
 (c)
Tenant shall not make any Alterations to the Data Center Licensed Space without Landlord’s prior written consent, which consent may be withheld in Landlord’s sole discretion. Notwithstanding the foregoing, Tenant shall be permitted to
install additional equipment in the Data Center Licensed Space or replace existing equipment in the Date Center Licensed Space, provided that (i) the power consumed following such installation (taking into account all other installations) is
not more than twenty percent (20%) of the power consumed the previous year, (ii) Tenant delivers to Landlord at least 180 days prior written notice of such installation, (iii) Tenant otherwise complies with the terms and conditions
set forth in Article 7 which terms and conditions shall apply to Alterations to the Data Center Licensed Space with the same force and effect, and (iv) the costs of such installation shall be borne solely by Tenant except to the extent
Landlord determines, in its reasonable discretion, that such installation benefits both Landlord and Tenant, in which case such installation shall be performed by Landlord and the cost thereof shall be treated as an Operating Expense. 

(d) At or prior to the expiration or earlier termination of this Lease, Tenant shall remove Tenant’s Property from the
Data Center Licensed Space and shall restore, at Tenant’s sole cost and expense, the Data Center Licensed Space in a manner reasonably satisfactory to Landlord. All Tenant’s Property remaining in the Data Center Licensed Space following
the expiration or earlier termination of this Lease shall be deemed abandoned and may, at the election of Landlord, either be retained as Landlord’s property or may be removed from the Data Center Licensed Space by Landlord at Tenant’s
expense. 
 40.3 Tenant acknowledges that neither Landlord nor Landlord’s agents has made any representations nor promises with respect
to the fitness or suitability of the Licensed Space for any purposes intended by Tenant therefor. Tenant shall not look to Landlord to supply or provide any security, material, services, repairs, alterations or property whatsoever in connection with
the Licensed Space except as expressly set forth in Article 8. Subject to Section 8.1 hereof, Tenant shall, throughout the term of the applicable Licensed Space, take good care of the Licensed Space and the fixtures and equipment
therein, and at Tenant’s sole cost and expense, make all repairs thereto as and when needed to preserve them in good working order and condition, reasonable wear and tear, obsolescence and damage from the elements, fire or other casualty,
excepted. Without limiting the terms of Section 15.1, Landlord shall have the right to enter the Licensed Space at reasonable hours, upon reasonable prior notice to Tenant, for the purpose of showing the same to (i) prospective
purchasers, mortgagees and tenants or (ii) any other persons to the extent such showing relates to sustainable design efforts, improvements, and/or initiatives at the Campus.

 40.4 Tenant shall secure, and keep in full force and effect, such supplementary insurance with
respect to the Licensed Space as Landlord may reasonably require from time to time. The rights granted in respect of the Licensed Space are given in connection with, and as part of the rights created under, this Lease and are not separately
transferable or assignable. This Article 40 does not, and shall not be deemed to, constitute a lease or a conveyance of the Licensed Space by Landlord to Tenant or to confer upon Tenant any right, title, estate or interest in the Licensed
Space. This Article 40 grants to Tenant only a personal privilege to occupy the Licensed Space and maintain and use the equipment therein on the terms and conditions set forth herein. 

ARTICLE 41 
 MISCELLANEOUS

 41.1 If any of the provisions of this Lease, or the application thereof to any person or circumstances, shall, to any extent, be
invalid or unenforceable, the remainder of this Lease, or the application of such provision or provisions to persons or circumstances other than those as to whom or which it is held invalid or unenforceable, shall not be affected thereby, and every
provision of this Lease shall be valid and enforceable to the fullest extent permitted by law. 
 41.2 This Lease shall be governed in all
respects by the laws of the Commonwealth of Pennsylvania without giving effort to the principles of conflicts of law. 
 41.3 If, in
connection with obtaining financing for the Buildings, a bank, insurance company or other lending institution shall request reasonable modifications to this Lease as a condition to such financing, Tenant will not unreasonably withhold its consent
thereto, provided that such modifications do not materially and adversely affect Tenant’s rights or obligations hereunder. 
 41.4
Wherever it is specifically provided in this Lease that a party’s consent is not to be unreasonably withheld, a response to a request for such consent shall also not be unreasonably conditioned or delayed. If either Landlord or Tenant considers
that the other has unreasonably withheld or delayed a consent (where such standard is applicable), it shall so notify the other party within thirty (30) days after receipt of notice of denial of the requested consent or, in case notice of
denial is not received within ten (10) days after making its request for the consent, within ten (10) days thereafter. Tenant hereby waives any claim against Landlord which it may have based upon any assertion that Landlord has
unreasonably withheld or unreasonably delayed any consent required hereunder, and Tenant agrees that its sole remedy shall be an action or proceeding to enforce any such provision or for specific performance, injunction or declaratory judgment. In
the event of such a determination, the requested consent shall be deemed to have been granted; however, Landlord shall have no liability to Tenant for its refusal or failure to give such consent. The sole remedy for Landlord’s unreasonably
withholding or delaying of consent shall be as provided in this Section 41.4. Notwithstanding anything to the contrary provided in this Lease, in any instance where the consent of a ground lessor and/or a mortgagee is required, Landlord
shall not be required to give its consent until and unless such ground lessor and/or mortgagee has given its consent. Landlord agrees to seek such consent if Landlord would otherwise consent in such instance. 

  
 47 

 41.5 The person(s) executing this Lease on behalf of Tenant and Landlord hereby represent and
warrant that they have been duly authorized to execute this Lease for and on behalf of their respective parties. 
 41.6 The listing of any
name other than that of Tenant, whether on the doors of the Premises, on the Building directory, if any, or otherwise, shall not operate to vest any right or interest in this Lease or in the Premises, nor shall it be deemed to be the consent of
Landlord to any assignment or transfer of this Lease, to any sublease of the Premises, or to the use or occupancy thereof by others. 
 41.7
In the event that Landlord or Tenant places the enforcement of this Lease or the collection of any Minimum Rent or additional rent due, or to become due hereunder, or recovery of the possession of the Premises, in the hands of an attorney, or files
suit upon the same, Landlord shall recover its reasonable attorneys’ fees, disbursements and court costs from Tenant in connection with such matter. The provisions of this Section 41.7 shall survive the expiration or earlier
termination of this Lease. 
 41.8 Landlord and Tenant understand, agree, and acknowledge that (i) this Lease has been freely
negotiated by both parties and (ii) in any controversy, dispute, or contest over the meaning, interpretation, validity, or enforceability of this Lease or any of its terms or conditions, there shall be no inference, presumption, or conclusion
drawn whatsoever against either party by virtue of that party having drafted this Lease or any portion thereof. 
 41.9 Tenant represents
and warrants to Landlord that (a) Tenant and each person or entity directly or indirectly owning an interest in Tenant is (1) not currently identified on the Specially Designated Nationals and Blocked Persons List maintained by the Office
of Foreign Assets Control of the Department of the Treasury (“OFAC”) and/or on any other similar list maintained by OFAC pursuant to any authorizing statute, executive order or regulation (collectively, the “List”),
and (2) not a person or entity with whom a citizen of the United States is prohibited to engage in transactions by any trade embargo, economic sanction, or other prohibition of United States law, regulation, or Executive Order of the President
of the United States, (b) none of the funds or other assets of Tenant constitute property of, or are beneficially owned, directly or indirectly, by, any Embargoed Person, (c) no Embargoed Person has any interest of any nature whatsoever in
Tenant (whether directly or indirectly), (d) none of the funds of Tenant have been derived from any unlawful activity with the result that the investment in Tenant is prohibited by law or that this Lease is in violation of law, and
(e) Tenant has implemented procedures, and will consistently apply those procedures, to ensure the foregoing representations and warranties remain true and correct at all times. The term “Embargoed Person” means any person,
entity or government subject to trade restrictions under U.S. law, including but not limited to, the International Emergency Economic Powers Act, 50 U.S.C. §1701 et seq., The Trading with the Enemy Act, 50 U.S.C. App. 1 et seq., and any
Executive Orders or regulations promulgated thereunder with the result that the investment in Tenant is prohibited by law or Tenant is in violation of law. 

(a) Tenant covenants and agrees (i) to comply with all Legal Requirements relating to money laundering, anti-terrorism, trade embargos
and economic sanctions, now or hereafter in effect, (ii) to immediately notify Landlord in writing if any of the representations, 

  
 48 

 
warranties or covenants set forth in this Section 41.9 are no longer true or have been breached or if Tenant has a reasonable basis to believe that they may no longer be true or have
been breached, (iii) not to use funds from any “Prohibited Person” (as such term is defined in the September 24, 2001 Executive Order Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or
Support Terrorism) to make any payment due to Landlord under this Lease and (iv) at the request of Landlord, to provide such information as may be reasonably requested by Landlord to determine Tenant’s compliance with the terms hereof.

 (b) Tenant hereby acknowledges and agrees that Tenant’s inclusion on the List at any time during this Lease Term shall be a material
default of this Lease. Notwithstanding anything to the contrary contained herein, including but not limited to Tenant’s rights under Section 14.8, Tenant shall not permit the Premises or any portion thereof to be used or occupied by
any person or entity on the List or by any Embargoed Person (on a permanent, temporary or transient basis), and any such use or occupancy of the Premises by any such person or entity shall be a material default of this Lease. 

41.10 Landlord hereby represents and warrants to Tenant that, on the date hereof, Landlord is primarily engaged in the design and
manufacturing of ceiling systems. Tenant hereby represents and warrants to Landlord that, on the date hereof, Tenant is primarily engaged in the design and manufacturing of flooring systems. In the event that either Landlord or Tenant intends on
entering into a merger, consolidation, acquisition or other transaction (each a “Corporate Transaction”) that would result in either party expanding into the production, manufacturing, design or sale of any product other than as
represented herein, then (i) Landlord or Tenant, as applicable, shall notify the other party in writing no less than ten (10) days prior to the effective date of the proposed Corporate Transaction and (ii) the parties shall discuss in
good faith whether any changes or modifications should be made with respect to Tenant’s access to and/or usage of the Common Areas under this Lease to ensure that adequate controls are in place to protect the respective interests of Landlord
and Tenant, including, without limitation, any controls relating to security and confidentiality. 
 41.11 This Lease may be executed in
several counterparts, each of which counterparts shall be deemed an original instrument and all of which together shall constitute a single agreement. Any signature page to any counterpart may be detached from such counterpart without impairing the
legal effect of the signatures thereon and thereafter attached to another counterpart identical thereto except having attached to it additional signature pages. 

[end of agreement; signatures follow on the next page]
