 3. Additional Space Improvements. 
 (a) Landlord shall provide Tenant with a tenant improvement allowance for the construction of the tenant improvements to the Additional Space in the
amount of Seventy-Three Thousand Two Hundred Dollars ($73,200.00) (the “Additional Space Improvement Allowance”). The Additional Space Improvement Allowance shall be applied toward construction, engineering, professional,
telecommunication, design, project management, plan review, permits, architecture, voice and data cabling and other costs and expenses associated with the Additional Space Improvements (as hereinafter defined) to the Additional Space and shall be
paid by Landlord upon the receipt of proper documentation from Tenant that such work has been done. Landlord shall be responsible for the payment of all costs and expense associated with improvements to the Additional Space up to the Additional
Space Improvement Allowance, whether such improvements are performed by Landlord, Duke Construction Limited Partnership, any other subsidiary or affiliate of Landlord, Tenant or any other person or entity, and Tenant shall have no responsibility
therefor. Any cost or expense incurred by Landlord and approved by Tenant in connection with the Additional Space Improvements to the Additional Space in excess of the Additional Space Improvement Allowance (the “Excess”) shall be borne by
Tenant and shall be paid by Tenant to Landlord within thirty (30) days of Tenant’s receipt of an invoice from Landlord providing sufficient detail and documentation for such costs and expenses. Failure by Tenant to pay any portion of the
Excess as aforesaid is an event of default hereunder. 
 (b) Following the date of
this Amendment, Tenant will work with a space planner to develop a space plan for the Additional Space that is reasonably acceptable to Landlord (the “Space Plan”). Within thirty (30) days after Landlord’s receipt of
the Space Plan, Tenant shall prepare and submit to Landlord a set of plans and specifications and/or construction drawings (the “Plans and Specifications”) prepared by an architect reasonably acceptable to Landlord covering all work to be
performed by Landlord in constructing the leasehold improvements to the Additional Space in accordance with the Space Plan (the “Additional Space Improvements”). Landlord shall participate in the design meetings with Tenant’s
architect to maintain Landlord’s building standard and to provide preconstruction cost estimating. Landlord shall have ten (10) days after receipt of the Plans and Specifications in which to review the Plans and Specifications and to give
Tenant written notice of Landlord’s approval of the Plans and Specifications or its requested changes to the Plans and Specifications. Tenant shall have no right to request any leasehold improvements or any changes to the Plans and
Specifications that would materially alter the Additional Space, the exterior appearance or basic nature of the Building, or the Building systems. If Landlord fails to approve or request changes to the Plans and Specifications within ten
(10) days after its receipt of the Plans and Specifications, then Landlord shall be deemed to have approved the Plans and Specifications and the same shall thereupon be final. If Landlord requests any changes to the Plans and Specifications,
Tenant shall make those changes which are reasonably requested by Landlord and shall within ten (10) business days of its receipt of such request submit the revised portion of the Plans and Specifications to Landlord. Landlord may not
thereafter disapprove the revised portions of the Plans and Specifications unless Tenant has unreasonably failed to incorporate reasonable comments of Landlord and, subject to the foregoing, the Plans and Specifications, as modified by said
revisions, shall be deemed to be final upon the submission of said revisions to Landlord. Landlord shall at all times in its review of the Plans and Specifications, and of any revisions thereto, act reasonably and in good faith. Landlord agrees to
confirm Landlord’s consent to the Plans and Specifications in writing within three (3) business days following Tenant’s written request therefor. 

 (c) Following Landlord’s approval (or deemed approval) of the Plans and Specifications, Landlord
shall solicit competitive bids from at least three (3) subcontractors for each major trade. Landlord shall provide Tenant with Landlord’s form for prequalifying subcontractors, attached hereto as Exhibit A and incorporated herein,
and its current list of approved subcontractors for each major trade, attached hereto as Exhibit B and incorporated herein. Tenant shall have the right to provide Landlord with a proposed subcontractor for each major trade which may or may
not be on Landlord’s approved list, and provided such subcontractor meets with Landlord’s reasonable approval, such subcontractor shall have the right to enter a bid. Upon Tenant’s request, Landlord shall also obtain a description of
the base warranty and any extended warranty terms relating to any equipment, machinery, trade fixtures or other personal property to be installed in connection with the Additional Space Improvements. Landlord and Tenant shall review the bids and
warranties, if applicable, jointly and Tenant shall select one subcontractor for each item bid. Promptly following the selection of a subcontractor for each major trade, Landlord shall deliver to Tenant a statement of the cost to construct and
install all of the Additional Space Improvements (the “Cost Statement”). Tenant acknowledges and agrees that (i) the cost to construct and install the Additional Space Improvements shall include a six percent (6%) fee plus
(A) Landlord’s actual overhead expenses associated with the Additional Space Improvements that includes preconstruction and project management, administrative support, telephones, utilities, etc., and (B) Landlord’s actual cost
of general conditions associated with the Additional Space Improvements that include, but are not limited to, permits, onsite supervision, temporary utilities, temporary facilities and project cleanup, (such overhead and general conditions shall not
exceed eight percent (8%) of the total construction costs for the Additional Space Improvements), and (ii) said fee, overhead and general conditions shall be included in the Cost Statement and applied against the Additional Space
Improvement Allowance (as hereinafter defined). Tenant agrees to acknowledge the Cost Statement in writing within five (5) business days following Landlord’s written request therefor. 
 (d) Landlord shall provide Tenant with a proposed schedule for the construction and installation of the Additional Space Improvements that is reasonably
acceptable to Tenant and shall perform the construction in accordance with such schedule and the Plans and Specifications, subject to extensions for Force Majeure Delays and Tenant Delays (as hereinafter defined). Landlord shall notify Tenant of any
material changes to said schedule as a result of such Force Majeure Delays and Tenant Delays. In the event the Additional Space Improvements are not Substantially Completed (as hereafter defined) in accordance with the schedule as extended by Force
Majeure Delays and Tenant Delays, Tenant shall receive one day of rent abatement for each day of delay until the Additional Space Improvements are Substantially Completed. Tenant agrees to coordinate with Landlord regarding the installation of
Tenant’s phone and data wiring and any other trade related fixtures that will need to be installed in the Additional Space prior to Substantial Completion. In addition, if and to the extent permitted by applicable laws, rules and ordinances,
Tenant shall have the right to enter the Additional Space for fifteen (15) days prior to the anticipated date for Substantial Completion (as such date may be modified from time to time) in order to install fixtures and otherwise prepare the
Additional Space for occupancy. During any entry prior to the Substantial Completion of the Additional Space Improvements (i) Tenant shall not interfere with Landlord’s completion of the Additional Space Improvements, and (ii) Tenant
shall cause its personnel and contractors to comply with the terms and conditions of Landlord’s rules of conduct (which Landlord agrees to furnish to Tenant upon request). 
 (e) Tenant shall have the right to request changes to the Plans and Specifications at any time by way of written change order (each, a “Change
Order”, and collectively, “Change Orders”). Provided such Change Order is reasonably acceptable to Landlord, Landlord shall prepare and submit promptly to Tenant a memorandum setting forth the impact on cost and 

 
schedule resulting from said Change Order (the “Change Order Memorandum of Agreement”). Tenant shall, within five (5) business days following
Tenant’s receipt of the Change Order Memorandum of Agreement, either (i) execute and return the Change Order Memorandum of Agreement to Landlord, in which case the Cost Statement shall be deemed modified automatically to take into account
said Change Order, (ii) retract its request for the Change Order or (iii) amend its proposed Change Order, in which case Landlord shall prepare a new Change Order Memorandum of Agreement and Tenant shall respond as provided herein.

 (f) For purposes of this Amendment “Substantial Completion” (or any grammatical variation thereof) shall mean completion of
construction of the Additional Space Improvements, subject only to punchlist items to be identified by Landlord and Tenant in a joint inspection of the Additional Space prior to Tenant’s occupancy, the completion of which will not materially
affect Tenant’s use and occupancy of, or ability to obtain an occupancy permit for the Additional Space which completion and punchlist items shall be evidenced by a writing signed by Tenant by Tenant and Landlord (Tenant acknowledging, however,
that even if Landlord has Substantially Completed the Additional Space Improvements, Landlord may not be able to obtain an occupancy permit for the Additional Space because of the need for completion of all or a portion of improvements being
installed in the Additional Space directly by Tenant). “Tenant Delay” shall mean any delay in the completion of the Additional Space Improvements to the extent attributable to Tenant, including, without limitation, (i) Tenant’s
failure to meet any time deadlines specified herein, (ii) the performance of any other work in the Additional Space by any person, firm or corporation employed by or on behalf of Tenant, or any failure to complete or delay in completion of such
work, and (iii) any other act or omission of Tenant. “Force Majeure Delay” shall mean any delay in the performance of any obligation by a party hereunder when such delay is occasioned by causes beyond its control due to act of God,
adverse weather, fire, earthquake, flood, explosion, war, invasion, insurrection, riot, mob violence, sabotage, vandalism, failure of transportation, strikes, lockouts, litigation, condemnation, requisition, governmental restrictions including
inability or delay in obtaining governmental consents, inspections or permits, laws or orders of governmental, civil, military or naval authorities, or any other cause outside a party’s control, whether similar or dissimilar to the foregoing.

 (g) Landlord hereby warrants the Additional Space Improvements for a period of one (1) year following the date of Substantial
Completion. Landlord agrees to assign any and all manufacturers’ warranties or extended warranties, if obtained, directly to the Tenant, which warranties shall include, but not be limited to, the standard warranties available from the
manufacturers, and if not assignable, shall cooperate with Tenant to enforce such warranties. 
 (h) Notwithstanding anything herein to the
contrary, Tenant must use the Additional Space Improvement Allowance by October 1, 2007, or Tenant shall have no further right to use the Additional Space Improvement Allowance. 
 (i) All shelves, bins, machinery and other trade fixtures installed in connection with any Additional Space Improvements to the Additional Space may be
removed by Tenant in accordance with the provisions of Paragraph 5 of the Lease. 

 4. Parking. Tenant shall be entitled to four (4) parking spaces for every 1,000 rentable
square feet of the Premises in the parking areas established for the Building. All such parking spaces shall be on a first-come, first served basis. 
 5. Alterations. Paragraph 5 of the Lease is hereby amended to provide that Tenant shall have the right to perform interior alterations to the Additional Space pursuant to Paragraph 5 of the Lease. Prior to
Tenant’s undertaking of any such alterations to the Additional Space, Tenant shall submit to Landlord for review and approval a set of plans detailing such alterations. Landlord shall designate at the time of such review whether such
alterations must be removed at the termination of the Lease. 
 6. Generator. Tenant shall have the right to remove the existing
generator serving the Premises; provided, however, that Tenant shall, at its cost and expense, repair any damage to the Premises caused by the removal of such generator and shall restore the Premises to the condition existing as of the Expansion
Date, reasonable wear and tear excepted. 
 7. Effective Date. The provisions of this Amendment shall be and become effective as of
the date and year first above written. 
 8. Severability. In the event any term, covenant or condition of this Amendment, the Lease,
or any amendments thereto shall to any extent be invalid or unenforceable, the remainder shall not be affected thereby and each term, covenant or condition shall be valid and enforceable to the full extent permitted by law. 
 9. Successors and Assigns. This Amendment shall apply to, inure to the benefit of, and be binding upon the parties hereto and upon their
respective heirs, legal representatives, successors and permitted assigns, except as otherwise provided herein. 
 10. Authority of
Tenant. Tenant certifies to Landlord that it is authorized to enter into this Amendment, and that those persons signing below on its behalf are authorized to do so, and shall promptly upon the request of Landlord provide a resolution to this
effect. 
 11. Interpretation. Although the printed provisions of this Amendment were drafted by Landlord, such fact shall not cause
this Amendment to be construed either for or against Landlord or Tenant. All capitalized terms, not otherwise defined, shall be defined as provided in the Lease. 
 12. Full Force and Effect. Except as modified hereby, the Lease remains unmodified and in full force and effect. 
 13. Governing Law. This Amendment shall be governed by and construed in accordance with the laws of the State of North Carolina. 

 14. Mutual Acknowledgment of Non-Existence of Claims. Landlord and Tenant acknowledge and agree
that as of the day hereof there are no known claims by either party against the other party hereto arising from the relationship as Landlord and Tenant, respectively, pursuant to the Lease, as amended. 
 15. Confidentiality. Except as otherwise required by law to be disclosed by Tenant the terms and provisions of the Lease, and this Amendment are
strictly confidential, are to be shared by Tenant only with its accountant, employees, and attorneys, and each of those parties shall be advised of the confidential nature of the lease, and this Amendment.

 WITNESSETH: 
 WHEREAS, pursuant to a Lease Agreement dated June 26, 1998 by and between Landlord and
Tenant, as amended by that certain First Lease Amendment to Lease Agreement dated October 28, 1998, and as amended by that certain Second Amendment to Lease Agreement dated October 1, 2002, and as further amended by that certain Third

good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by Landlord and Tenant, Landlord and Tenant amend the Agreement as follows: 
 1. Premises and Term. 
 (a) Premises.
Effective September 1, 2005 (the “Expansion Date”), subparagraph (a) of Article 1 of the Lease is hereby amended to provide that Tenant shall lease the Original Premises and the 150 Additional Space which together
shall consist of 83,719 rentable square feet of space and which space shall hereinafter collectively be referred to as the “Premises”. 
 (b) Term. Subparagraph (a) of Article 1 of the Lease is hereby modified to reflect
that the term of the 150 Additional Space shall commence on the Expansion Date, and shall expire on November 8, 2013 (the “Expansion Term”) which shall be coterminous with the existing Lease Term. 

 2. Base Rent, Operating Expenses and Security Deposit.

	 	“(a)	Base Rent, Additional Rent and operating expenses for the Original Premises shall continue to be due and payable as provided in the Lease. Base Rent for the Original Premises shall

 On November 8, 2008,
Tenant’s Base Rent for the entire Premises shall be adjusted to the then current Market Rent (as defined in the Lease) and taking into account the readjustment of the operating expenses as set out in Paragraph 2(b) of the Second Amendment;
provided, however, that in no event shall the Base Rent per square foot, as adjusted, be less than Tenant’s then current rent.” 
 (b) Operating Expenses. Tenant shall not be charged Operating Expenses on the 150 Additional Space for the period beginning September 1, 2005 through and including November 15, 2005; provided, however, that if any such

shall be 70.3% and shall be calculated consistently with the provision of paragraph 2(b)(ii) of the Lease. 
 3. 150 Additional Space
Improvements. 
 (a) Landlord shall provide Tenant with a tenant improvement allowance for the construction of the tenant improvements to
the 150 Additional Space in the amount of Twelve and 00/100 Dollars ($12.00) per rentable square foot of the 150 Additional Space (the “150 Additional Space Improvement Allowance”). The 150 Additional Space Improvement Allowance shall be
applied toward construction, engineering, professional, telecommunication, design, project management, plan review, permits, architecture, voice and data cabling and other costs and expenses associated with the 150 Additional Space Improvements (as
hereinafter defined) to the 150 Additional Space and shall be paid by Landlord upon the receipt of proper documentation from Tenant that such work has been done. Landlord shall be responsible for the payment of all costs and expense associated with
improvements to the 150 Additional Space up to the 150 Additional Space Improvement Allowance. Any cost or expense incurred by Landlord and approved by Tenant in connection with the 150 Additional Space Improvements to the 150 Additional Space in
excess of the 150 Additional Space Improvement Allowance (the “Excess”) shall be borne by Tenant and shall be paid by Tenant to Landlord within thirty (30) days of Tenant’s receipt of an invoice from Landlord providing sufficient
detail and documentation for such costs and expenses. Failure by Tenant to pay any portion of the Excess as aforesaid is an event of default hereunder. If the tenant has not used the 150 Additional Space Improvement Allowance within the first year
of the Effective Date or the 150 Additional Space Improvement Allowance exceeds the Cost Statement (as hereinafter defined) (taking into account any increases or decreases resulting from any Change Orders), such savings shall be the property of
Tenant. 

 (b) Following the date of this Amendment, Tenant
will work with a space planner to develop a space plan for the 150 Additional Space that is reasonably acceptable to Landlord (the “Space Plan”). Within thirty (30) days after Landlord’s receipt of the Space Plan,
Tenant shall prepare and submit to Landlord a set of plans and specifications and/or construction drawings (the “Plans and Specifications”) prepared by an architect reasonably acceptable to Landlord covering all work to be performed by
Landlord in constructing the leasehold improvements to the 150 Additional Space in accordance with the Space Plan (the “150 Additional Space Improvements”). Landlord shall participate in the design meetings with Tenant’s
architect to maintain Landlord’s building standard and to provide preconstruction cost estimating. Landlord shall have ten (10) days after receipt of the Plans and Specifications in which to review the Plans and Specifications and to give
Tenant written notice of Landlord’s approval of the Plans and Specifications or its requested changes to the Plans and Specifications. Tenant shall have no right to request any leasehold improvements or any changes to the Plans and
Specifications that would materially alter the 150 Additional Space, the exterior appearance or basic nature of the Building, or the Building systems. If Landlord fails to approve or request changes to the Plans and Specifications within ten
(10) days after its receipt of the Plans and Specifications, then Landlord shall be deemed to have approved the Plans and Specifications and the same shall thereupon be final. If Landlord requests any changes to the Plans and Specifications,
Tenant shall make those changes which are reasonably requested by Landlord and shall within ten (10) business days of its receipt of such request submit the revised portion of the Plans and Specifications to Landlord. Landlord may not
thereafter disapprove the revised portions of the Plans and Specifications unless Tenant has unreasonably failed to incorporate reasonable comments of Landlord and, subject to the foregoing, the Plans and Specifications, as modified by said
revisions, shall be deemed to be final upon the submission of said revisions to Landlord. Landlord shall at all times in its review of the Plans and Specifications, and of any revisions thereto, act reasonably and in good faith. Landlord agrees to
confirm Landlord’s consent to the Plans and Specifications in writing within three (3) business days following Tenant’s written request therefor. 
 (c) Following Landlord’s approval (or deemed approval) of the Plans and Specifications, Landlord shall solicit competitive bids from at least three (3) subcontractors for each major trade. Landlord shall
provide Tenant with Landlord’s form for prequalifying subcontractors, attached hereto as Exhibit A and incorporated herein, and its current list of approved subcontractors for each major trade, attached hereto as Exhibit B and
incorporated herein. Tenant shall have the right to provide Landlord with a proposed subcontractor for each major trade which may or may not be on Landlord’s approved list, and provided such subcontractor meets with Landlord’s reasonable
approval, such subcontractor shall have the right to enter a bid. Landlord shall also obtain a description of the base warranty and any extended warranty terms relating to any equipment, machinery, trade fixtures or other personal property to be
installed in connection with the 150 Additional Space Improvements. Landlord and Tenant shall review the bids and warranties, if applicable, jointly and Tenant shall select one subcontractor for each item bid. Promptly following the selection of a
subcontractor for each major trade, Landlord shall deliver to Tenant a statement of the cost to construct and install all of the 150 Additional Space Improvements (the “Cost Statement”). Tenant acknowledges and agrees that (i) the
cost to construct and install the 150 Additional Space Improvements shall include a six percent (6%) fee plus (A) Landlord’s actual overhead expenses associated with the 150 Additional Space Improvements that includes preconstruction
and project management, administrative support, telephones, utilities, etc., and (B) Landlord’s actual cost of general conditions associated with the 150 Additional Space Improvements that include, but are not limited to, permits, onsite
supervision, temporary utilities, temporary facilities and project 

 
cleanup, (such overhead and general conditions shall not exceed eight percent (8%) of the total construction costs for the 150 Additional Space
Improvements), and (ii) said fee, overhead and general conditions shall be included in the Cost Statement and applied against the 150 Additional Space Improvement Allowance (as hereinafter defined). Tenant agrees to acknowledge the Cost
Statement in writing within ten (10) business days following Landlord’s written request therefor. 
 (d) Landlord shall provide
Tenant with a proposed schedule for the construction and installation of the 150 Additional Space Improvements that is reasonably acceptable to Tenant and shall perform the construction in accordance with such schedule and the Plans and
Specifications, subject to extensions for Force Majeure Delays and Tenant Delays (as hereinafter defined). Landlord shall notify Tenant of any material changes to said schedule as a result of such Force Majeure Delays and Tenant Delays. In the event
the 150 Additional Space Improvements are not Substantially Completed (as hereafter defined) in accordance with the schedule as extended by Force Majeure Delays and Tenant Delays, Tenant shall receive one day of rent abatement for each day of delay
until the 150 Additional Space Improvements are Substantially Completed. Tenant agrees to coordinate with Landlord regarding the installation of Tenant’s phone and data wiring and any other trade related fixtures that will need to be installed
in the 150 Additional Space prior to Substantial Completion. In addition, if and to the extent permitted by applicable laws, rules and ordinances, Tenant shall have the right to enter the 150 Additional Space for fifteen (15) days prior to the
anticipated date for Substantial Completion (as such date may be modified from time to time) in order to install fixtures and otherwise prepare the 150 Additional Space for occupancy. During any entry prior to the Substantial Completion of the 150
Additional Space Improvements (i) Tenant shall not interfere with Landlord’s completion of the 150 Additional Space Improvements, and (ii) Tenant shall cause its personnel and contractors to comply with the terms and conditions of
Landlord’s rules of conduct (which Landlord agrees to furnish to Tenant upon request). 
 (e) Tenant shall have the right to request
changes to the Plans and Specifications at any time by way of written change order (each, a “Change Order”, and collectively, “Change Orders”). Provided such Change Order is reasonably acceptable to Landlord, Landlord shall
prepare and submit promptly to Tenant a memorandum setting forth the impact on cost and schedule resulting from said Change Order (the “Change Order Memorandum of Agreement”). Tenant shall, within five (5) business days following
Tenant’s receipt of the Change Order Memorandum of Agreement, either (i) execute and return the Change Order Memorandum of Agreement to Landlord, in which case the Cost Statement shall be deemed modified automatically to take into account
said Change Order, (ii) retract its request for the Change Order or (iii) amend its proposed Change Order, in which case Landlord shall prepare a new Change Order Memorandum of Agreement and Tenant shall respond as provided herein.

 (f) For purposes of this Amendment “Substantial Completion”
(or any grammatical variation thereof) shall mean completion of construction of the 150 Additional Space Improvements, subject only to punchlist items to be identified by Landlord and Tenant in a joint inspection of the 150 Additional Space prior to
Tenant’s occupancy, the completion of which will not materially affect Tenant’s use and occupancy of, or ability to obtain an occupancy permit for the 150 Additional Space which completion and punchlist items shall be evidenced by a
writing signed by Tenant and Landlord (Tenant acknowledging, however, that even if Landlord has Substantially Completed the 150 Additional Space Improvements, Landlord may not be able to obtain an occupancy permit for the 150 Additional Space
because of the need for completion of all or a portion of improvements being installed in the 150 Additional Space directly by Tenant). “Tenant Delay” shall mean any delay in the completion of the 150 Additional Space Improvements to the
extent attributable to Tenant, including, without limitation, (i) Tenant’s failure to meet any time deadlines specified herein, (ii) the 

 
performance of any other work in the 150 Additional Space by any person, firm or corporation employed by or on behalf of Tenant, or any failure to complete
or delay in completion of such work, and (iii) any other act or omission of Tenant. “Force Majeure Delay” shall mean any delay in the performance of any obligation by a party hereunder when such delay is occasioned by causes beyond
its control due to act of God, adverse weather, fire, earthquake, flood, explosion, war, invasion, insurrection, riot, mob violence, sabotage, vandalism, failure of transportation, strikes, lockouts, litigation, condemnation, requisition,
governmental restrictions including inability or delay in obtaining governmental consents, inspections or permits, laws or orders of governmental, civil, military or naval authorities, or any other cause outside a party’s control, whether
similar or dissimilar to the foregoing. 
 (g) Landlord hereby warrants the 150 Additional Space Improvements for a period of one
(1) year following the date of Substantial Completion of the 150 Additional Space Improvements performed by Landlord. Landlord agrees to assign any and all manufacturers’ warranties or extended warranties, if obtained, directly to the
Tenant, which warranties shall include, but not be limited to, the standard warranties available from the manufacturers, and if not assignable, shall cooperate with Tenant to enforce such warranties. 
 (h) All shelves, bins, machinery and other trade fixtures installed in connection with any 150 Additional Space Improvements to the 150 Additional Space
may be removed by Tenant in accordance with the provisions of Paragraph 5 of the Lease. 
 4. Alterations. Paragraph 5 of the Lease is
hereby amended to provide that Tenant shall have the right to perform interior alterations to the 150 Additional Space pursuant to Paragraph 5 of the Lease. Prior to Tenant’s undertaking of any such alterations to the 150 Additional Space,
Tenant shall submit to Landlord for review and approval a set of plans detailing such alterations. Landlord shall designate at the time of such review whether such alterations must be removed at the termination of the Lease. 
 5. Effective Date. The provisions of this Amendment shall be and become effective as of the date and year first above written. 
 6. Severability. In the event any term, covenant or condition of this Amendment, the Lease, or any amendments thereto shall to any extent be
invalid or unenforceable, the remainder shall not be affected thereby and each term, covenant or condition shall be valid and enforceable to the full extent permitted by law. 
 7. Successors and Assigns. This Amendment shall apply to, inure to the benefit of, and be binding upon the parties hereto and upon their
respective heirs, legal representatives, successors and permitted assigns, except as otherwise provided herein. 
 8. Authority of
Tenant. Tenant certifies to Landlord that it is authorized to enter into this Amendment, and that those persons signing below on its behalf are authorized to do so, and shall promptly upon the request of Landlord provide a resolution to this
effect. 
 9. Interpretation. Although the printed provisions of this Amendment were drafted by Landlord, such fact shall not cause
this Amendment to be construed either for or against Landlord or Tenant. All capitalized terms, not otherwise defined, shall be defined as provided in the Lease. 

 10. Full Force and Effect. Except as modified hereby, the Lease remains unmodified and in full
force and effect. 
 11. Governing Law. This Amendment shall be governed by and construed in accordance with the laws of the State of
North Carolina. 
 12. Mutual Acknowledgment of Non-Existence of Claims. Landlord and Tenant acknowledge and agree that as of the day
hereof there are no known claims by either party against the other party hereto arising from the relationship as Landlord and Tenant, respectively, pursuant to the Lease, as amended. 
 13. Confidentiality. Except as otherwise required by law to be disclosed by Tenant the terms and provisions of the Lease, and this Amendment are
strictly confidential, are to be shared by Tenant only with its accountant, employees, and attorneys, and each of those parties shall be advised of the confidential nature of the lease, and this Amendment.
