(ii) Tenant shall provide written notice to Landlord, as to Tenant’s decision to lease or not to lease the Additional Space within five
(5) business days after Landlord’s Notice is received. If Tenant does provide to Landlord notice to lease the Additional Space, Landlord and Tenant will execute a lease amendment adding the Additional Space to the Premises within twenty
(20) days after Landlord’s receipt of Tenant’s notice of intent to lease on all the same terms provided to the Third Party. If Tenant does not provide written notice to Landlord within five (5) business days after receipt of the
Landlord’s Notice, Tenant will have been deemed to have waived its right to lease the Additional Space and Landlord shall be free to enter into a lease with the Third Party. Should all or any portion of the Additional Space become vacant

 (iii) The rights provided to Tenant in this Section are
personal to the Tenant and may not be assigned in connection with an assignment of this Lease, subletting of the Premises or otherwise, except for any Permitted Transferee (as hereinafter defined).

default by Tenant hereunder, Tenant shall, by written notice to Landlord on or prior to February 6, 2011 (time being of the essence), have the right to terminate this Lease and all of its obligations hereunder (as of the date of giving such
notice), and the parties hereto shall have no further obligation to each other hereunder.

hereof will have lapsed. Failure of Tenant to comply strictly with the provisions of this subparagraph will render the rights of Tenant in this subparagraph null and void. The rights granted to Tenant in this subparagraph are personal to Tenant and
will not inure to the benefit of any successor or assign of Tenant, except for any Permitted Transferee.

opinion, constitutes the market rate, or (c) if Tenant does not respond, Tenant shall be deemed to agree. In the event Tenant agrees, then the Base Annual Rent set forth in Landlord’s said notice shall be deemed the market rate. In the
event Tenant disagrees as provided in clause (b) above, the following procedure shall be used in determining the market rate: The parties shall use due diligence to attempt to agree upon the market rate within seven (7) business days
following the foregoing fifteen (15) day period, but, if they do not so agree, then at the request of either party to the other (the “Initial Request”), the parties shall jointly choose a real estate broker (who shall have had at
least ten (10) years experience as a broker in commercial office leasing in the Durham, North Carolina area) and who has not been employed by either party, whose decision shall be final and binding. If the parties do not agree upon such a third
party broker and notify in writing the other thereof within seven (7) business days of the Initial Request, then within six (6) additional business days each party shall choose a real estate broker (having the foregoing credentials) and
notify in writing the other thereof, and the joint decision of such real estate brokers regarding the market rate shall be final and binding (or, failing such notice, or if such choice is made, failing notice to the other within such six
(6) additional business day period, the decision of one such real estate broker timely chosen and noticed shall be final and binding). If the two (2) real estate brokers timely chosen and noticed do not agree within seven (7) business
days of the end of the six (6) business day period mentioned above during which they were chosen, then they shall choose a third such real estate broker (having the foregoing credentials) within five (5) business days, and the decision of
such third real estate broker regarding the market rate shall be final and binding. 
 5.    Rent.
Beginning on the Rent Commencement Date and continuing thereafter throughout the Term, Tenant will pay the Rent in monthly installments in advance, without demand, deduction or offset, in lawful money of the United States commencing on the Rent
Commencement Date, and continuing on the first day of each and every month thereafter until the Termination Date. Rent payments for any fractional calendar month at the end, or the beginning of the term of the Lease, will be prorated. In the event
Tenant fails to pay any installment of Rent hereunder within ten days of the due date of such installment, Tenant will pay to Landlord on demand a late charge in an amount equal to four percent (4%) of such installment. The provision for such late
charge will be in addition to all of Landlord’s other rights and remedies hereunder or at law and will not be construed as liquidated damages or as limiting Landlord’s remedies in any manner. Commencing with the second Lease Year
hereunder, Base Annual Rent will increase on each anniversary of the Rent Commencement Date by the Base Annual Rent Escalation over the Base Annual Rent paid the previous Lease Year. 

  
 11 

 Commencing January 1 of the year following the Commencement Date and continuing
thereafter for each calendar year during the Term, Landlord will present to Tenant Tenant’s Forecast Operating Expenses. Tenant will pay without deduction, offset, or counter claim, and otherwise in the same manner as Base Annual Rent on the
first day of each calendar month during the Term, an amount equal to one twelfth (1/12) of Tenant’s Forecast Operating Expenses as Additional Rent. From time to time during any calendar year, Landlord may revise Tenant’s Forecast Operating
Expense and adjust Tenant’s monthly payments to reflect Landlord’s such revisions. Promptly after the full execution of this Lease (and delivery to Tenant of a copy thereof), Tenant shall pay Landlord the first month’s Rent due
hereunder. 
 Notwithstanding the foregoing, and provided there is no default or event of default hereunder by Tenant, Base Annual Rent (but
not Operating Expenses) shall be abated hereunder for the first five (5) months after the Commencement Date (the “Rent Abatement”). Tenant will be responsible for its Proportionate Share of the Operating Expenses for the Building as
well as its utilities and janitorial services. 
 6.    Operating Expenses. The accounting of the
Operating Expenses will be performed in accordance with Generally Accepted Accounting Principles. For the purpose of calculating the Operating Expenses, no Controllable Expense will increase more than five percent (5%) over the charge paid by Tenant
the previous Lease Year. 
 If the average occupancy rate of the Building Rentable Area will be less than ninety-five percent (95%) during
any calendar year, or if any tenant is separately paying for (or does not require) electricity, janitorial, or other services furnished to its premises, then, for purposes of calculating Operating Expenses, the Operating Expenses for such
period that vary with the level of occupancy of the Building or Project will be increased by the additional costs and expenses that Landlord reasonably estimates would have been incurred if the average occupancy rate had been ninety-five percent
(95%) for such period. In no event will the Project tenants be required to pay, in the aggregate, more than 100% of the actual Operating Expenses of the Building or Project for any calendar year, and Tenant will not be required to pay more than one
hundred percent (100%) of its Proportionate Share of the total increase in Operating Expenses actually incurred for the calendar year, with such actual Operating Expenses to be determined and payments reconciled through the process described above.
At Tenant’s written request, Landlord will provide information sufficient to disclose or quantify adjustments made to each category of Operating Expenses increased pursuant to the provisions of this Section. For the purpose of this Section, the
term “Building” will be deemed to include the roof of the Building and any extensions therefrom, courtyards, sidewalks, landscaping, and all other areas, facilities, improvements, and appurtenances relating to any of the foregoing;
provided, however, that Operating Expenses for the Building will not include Operating Expenses for the Project. 
 Within 120 days after
the end of each calendar year, Landlord will submit to Tenant the Statement showing (i) the actual Tenant’s Proportionate Share of the amount by which Operating Expenses incurred during the preceding calendar year exceed the Tenant’s
Forecast Operating Expenses, (ii) the amount thereof paid by Tenant, and (iii) the balance due or the overpayment. If there is a balance due, Tenant will pay the balance due as Additional Rent within thirty (30) days following receipt
of such Statement. If the Statement indicates an overpayment, then Landlord will credit 

  
 12 

 
the net overpayment toward Tenant’s next estimated payment(s) pursuant to this Section or if at the end of the Term, will refund such excess to Tenant. Tenant or its designated
representative, at its sole expense, will have the right once per calendar year during the Term to audit Landlord’s books and records relating to the Operating Expenses for the immediately preceding calendar year. This audit must take place on
a mutually agreeable date during reasonable business hours at Landlord’s office at the address stated above and only after Tenant has given Landlord at least fourteen (14) calendar days prior written notice of the date and time Tenant
desires to commence such audit. If Tenant elects to audit Landlord’s books and records, Tenant will have the right to perform an audit of the Operating Expenses for the immediately preceding two (2) calendar years, such audit to be
conducted by a reputable accounting firm reasonably approved by Landlord. If any such audit reveals an error by Landlord resulting in an overcharge to Tenant, then Landlord will promptly reimburse Tenant for the amount erroneously charged to
Tenant. Likewise, if any such audit reveals an error resulting in Tenant being undercharged, then Tenant will promptly reimburse Landlord for the amount of such deficiency. If any audit performed by Tenant reveals that the Operating Expenses in
total have been overstated by more than five percent (5%), Landlord will pay and/or reimburse Tenant for the cost of the audit not to exceed Two Thousand, Five Hundred Dollars ($2,500.00). 

7.     Utilities and Services. 

(a)    Landlord shall furnish connections for each utility to the Premises to include electricity, water
and sewer, and telephone as specified in Exhibit C. Landlord shall not be liable in any respect for damages to person, property or otherwise due to the interruption in any utility to the Building, nor be construed as an eviction of Tenant, nor work
an abatement of rent, nor relieve Tenant from fulfillment of any covenant or agreement hereof nor give rise to any right or remedy by Tenant unless caused by the gross negligence or willful misconduct of Landlord. Landlord shall provide conduit and
boxes for phone and data at the Premises. Tenant shall bear the costs and be responsible for pulling cable for phone and data from the Demarcation closet (telephone closet) and providing cabling and jacks. 

(b)    Landlord shall provide the following services to Common Areas of the Building: 

(i)    Common Area Cleaning (M, W, T, F): (Restrooms, Halls, Stairs, Lobby, Elevator and Entrance): 

Clean and restock restrooms on 1st and
2nd floors 
 Clean elevator 

Sweep stairwell and spot mop for spills 

Vacuum carpet 
 Dust mop hard
surface floors and spot mop to remove spills 
 Clean entrance glass doors and sills 

Dust security desk and Lobby furniture; and 

Once Weekly: Dust and damp wipe stairwell railings. 

(ii) Lights on throughout Common Areas throughout the business day and parking lot illuminated every night 

  
 13 

 (iii) Security guard on duty Monday through Friday
8-5 
 (iv) HVAC to condition Common Areas during each business day with override after-hours (HVAC
annual service contracts included in Operating Expenses) 
 (v) Landscaping every 7-10 days with day

 (vi) Fire alarm and controlled access door system monitored 24/7
(contract paid through Operating Expenses) 
 (vii) Elevator preventative maintenance contract and service; and 

(viii) Routine maintenance of common areas including, but not limited to, bulb replacements, door adjustments, HVAC adjustments, plumbing
repairs, etc. 
 8.    Direct Tenant Expenses. Tenant will arrange for the provision of service and shall
pay directly to each service provider all charges for all electricity, gas, and other utilities, janitorial, telephone and internet/data used on or from the Premises, together with any taxes, penalties, surcharges or the like pertaining thereto.

 9.    Security Deposit. Promptly after the full execution of the Lease (with a copy thereof
delivered to Tenant), Tenant will provide Landlord with an amount equal to six (6) months of the Base Annual Rent, Seventy-Three Thousand Eight Hundred Forty-Five and 45/100 dollars ($73,845.45) to be held as Security Deposit. Provided that
Landlord reasonably approves the form and substance of such, Tenant may provide a Letter of Credit in lieu of cash. Any such Letter of Credit shall be irrevocable, unconditional, payable to the order of Landlord, from an issuer reasonably approved
by Landlord, in place for the Term of the Lease and any Renewal Terms hereof, and be for the full amount of the Security Deposit. Landlord will not be required to apply all or any portion of the Security Deposit with respect to any particular
violation or default by Tenant but Landlord may apply all or any portion (as reasonably required to effect a cure) of the Security Deposit to any violation, breach, or default by Tenant hereunder. Landlord will be entitled to hold the Security
Deposit in an account maintained by Landlord for such funds from all tenants of Landlord. Any interest paid on such an account will become a part of the Security Deposit, accrue to the benefit of the Tenant (less any customary bank fees or charges
for maintaining such account), and be delivered to Tenant upon termination of this Lease provided that the Security Deposit and interest thereon have not been applied by Landlord to an event of default hereunder. Tenant will reimburse Landlord for
such portions of the Security Deposit as Landlord will from time to time apply with respect to any violation, breach, or default by Tenant hereunder promptly upon written notice of such application by Landlord. Any portion of the Security Deposit
which has not been appropriated by Landlord in accordance with the provisions hereof will be returned to Tenant within thirty (30) days after the termination of this Lease. 

If Landlord conveys Landlord’s interest under this Lease, the Security Deposit, or any part thereof not previously applied, shall be
released by Landlord to Landlord’s grantee (to the extent not applied to any default by Tenant hereunder), and if so released, Tenant agrees to look solely to such grantee for the proper application and return thereof in accordance with the
Lease provided that Tenant receives written notice of such conveyance. Tenant agrees that Tenant will not assign, and that neither Landlord, nor its successors and assigns, will be bound by any such assignment, encumbrance or pledge, attempted
assignment, attempted pledge, or attempted encumbrance of the Security Deposit. 

  
 14 

 Any mortgagee or ground lessor will not be responsible to Tenant for the return or
application of the Security Deposit, whether or not it succeeds to the position of Landlord hereunder, unless the security deposit will have been received in hand by such mortgagee or ground lessor. 

Any unperformed obligations of Landlord or Tenant under this Section will survive the termination of the Lease, for whatever reason, or any
extension or renewal hereof. 
 Notwithstanding the foregoing and provided there is no default or event of default hereunder by Tenant (or
if Tenant has committed a default or event of default more than one (1) time in any twelve (12) month period, then regardless of whether same has been cured), Landlord shall reduce the Security Deposit by the equivalent of one
(1) month’s Base Annual Rent, Twelve Thousand Three Hundred Seven and 58/100 dollars ($12,307.58) every three (3) months during the Lease Term commencing upon the later of (i) the satisfactory repayment of Tenant’s loan as
reported on Precision BioSciences, Inc. Balance Sheet dated January 8, 2010, or (ii) December 31, 2011, until such time that the equivalent of one (1) month’s Base Annual Rent, Twelve Thousand Three Hundred Seven and 58/100
dollars ($12,307.58), remains as Security Deposit. With the third reduction of the Security Deposit, if paid as aforesaid, Landlord shall remit to Tenant the net interest that has accrued on the Security Deposit. Landlord shall provide Tenant
written notice of any reduction in the Security Deposit and within five (5) business days thereafter, Tenant will be responsible for the re-issuance of an approved Letter of Credit each time that Security
Deposit is eligible for reduction and until Tenant provides a re-issued Letter of Credit, Landlord shall have the right to use and draw upon the currently provided Letter of Credit. 

10.    Maintenance and Repairs. Landlord will maintain all Common Areas and Systems serving
the Common Areas, the roof, downspouts, gutters, foundation, and the exterior walls (and any structural interior walls or other structural elements) of the Building in good repair, reasonable wear and tear excepted. Tenant will repair, replace and
pay for, any damage to the foregoing caused by the negligence or misconduct of Tenant or any Tenant Party, or caused by Tenant’s default hereunder. The term “walls” as used herein will not include windows, glass or plate glass, doors,
special store fronts or office entries. Tenant will promptly give Landlord written notice of defect or need for repairs, after which Landlord will have reasonable opportunity to repair same or cure such defect. Landlord’s liability with respect
to any defects, repairs or maintenance for which Landlord is responsible under any of the provisions of this Lease will be limited to the cost of such repairs or maintenance or the curing of such defect. 

Tenant will at its own cost and expense maintain, repair and replace the entirety of the Premises (except those for which Landlord is
expressly responsible under the terms of this Lease) in as good condition as received (ordinary wear and tear excepted), promptly making all necessary repairs and replacements, including, but not limited to, heating, ventilation, cooling, plumbing,
telecommunications, electrical and any other systems (the “Systems”) within or serving the Premises, lighting fixtures, ballasts and bulbs, windows and window treatments, windows, glass and plate glass, doors, any special office entry,
interior walls, finish work, and floors and floor coverings within or serving the Premises unless any such damage is caused by parties other than Tenant or a Tenant Party. Landlord shall insure that the Systems will be in good working order and
condition upon the Commencement Date. Landlord shall assign to Tenant all warranties that 

  
 15 

 
are legally assignable, and if not assignable, shall cooperate with Tenant to enforce such warranties. Landlord agrees to assign, to the extent legally assignable, any and all manufacturers’
warranties for the Tenant Improvements, directly to the Tenant, which warranties shall include, but not be limited to, warranties for the Systems, which shall be the standard warranties available from the manufacturers. Additionally, Landlord
acknowledges and agrees that any replacements made to any Systems, or any material components thereof (during the last 24 months of the then-existing Lease Term), shall be made by Landlord, and amortized over its useful life, and charged as a
capital expense under the Operating Expense formula. 
 Subject to compliance with any notice and right to cure provisions contained in this
Lease, if Tenant shall fail to fulfill its obligations under this Section, the Landlord may enter upon the area of the Building or the Premises as required to perform the obligations of the Tenant, and will be entitled to reimbursement from the
Tenant for its actual costs and expenses in conducting such obligations. The Tenant will reimburse the Landlord for its actual costs and expense promptly upon demand made by the Landlord. The provisions of this subparagraph will not be interpreted
to obligate the Landlord to perform obligations of the Tenant. 
 Tenant will not damage any demising wall of the Building, or disturb the
integrity and support provided by any demising wall and will, at its sole cost and expense, promptly repair any damage or injury to any demising wall caused by Tenant or any Tenant Party. 

11.    Alterations. Except for the Tenant Improvements, Tenant will not make any alterations, additions or
improvements to the Premises (including, but not limited to, roof and wall penetrations without the prior written consent of Landlord (not to be unreasonably withheld, or delayed). Tenant may, without the consent of Landlord, but at its own cost and
expense and in a good workmanlike manner, erect such shelves, bins, machinery, movable lab benches, equipment, trade fixtures (defined as any fixtures used by Tenant in its specific business and not paid for by Landlord) and other non-structural interior improvements as it may deem advisable, without altering the basic character or structure of the Premises or improvements and without overloading or damaging the Premises or Building, and in
each case complying with all Applicable Laws. Tenant will not make any alterations, additions or improvements to the Premises which will contravene Landlord’s policies insuring against loss or damage by fire or other hazards, including but not
limited to commercial general liability, or which will prevent Landlord from securing such policies in companies reasonably acceptable to Landlord. If any such alterations, additions or improvements cause the rate of fire or other insurance on the
Premises by companies acceptable to Landlord to be increased beyond the minimum rate from time to time applicable to the Premises for permitted uses thereof (as reasonably documented by Landlord), Tenant will pay as Additional Rent the amount of any
such increase promptly upon demand by Landlord. Within thirty (30) days receipt of reasonable documentation from Landlord following the completion of any alteration, addition, or improvement at the Premises by Tenant that requires the prior
consent of Landlord, Landlord will be reimbursed for any reasonable outside consultant or design professional costs actually incurred by Landlord to review any plans or supervise construction work (not to exceed the lesser of $1,500.00 or 5% of
Tenant’s “hard” construction costs). No such reimbursement will be required for any alteration, addition or improvement that does not require the consent of Landlord. 

  
 16 

 Any and all alterations, additions, improvements, partitions and fixtures erected by Tenant
will be the property of Landlord and will remain at the Premises upon termination of the Lease or upon earlier vacating of the Premises. All shelves, bins, machinery, trade fixtures, and other interior
non-structural improvements installed by Tenant will remain the personal property of Tenant and may be removed by Tenant prior to the termination of this Lease provided such removal may be accomplished without
damage to the Premises or Building that cannot be repaired by Tenant as set forth in this subparagraph. Prior to vacating the Premises, Tenant will repair any damage to the Premises or Building as a result of any alteration, addition, improvement,
or repair to the Premises, or the removal of personal property or trade fixtures by Tenant, or any Tenant Party. Should Tenant fail to conduct any such repair within ten (10) days of written notice from Landlord, Landlord may, at its option,
perform same, and Tenant will remit payment to Landlord for the actual cost and expense incurred by Landlord in effecting such repair promptly upon demand. 

Tenant will have no authority, express or implied, to create or place any lien or encumbrance of any kind or nature whatsoever upon, or in any
manner to bind, the interest of Landlord in the Premises or to charge the rentals payable hereunder for any claim in favor of any person dealing with Tenant, including those who may furnish materials or perform labor for any construction or repairs,
and each such claim will affect and each such lien will attach to, if at all, only the leasehold interest granted to Tenant by this instrument. Tenant covenants and agrees that it will pay or cause to be paid all sums legally due and payable by it
on account of any labor performed or materials furnished in connection with any work performed on the Premises at the request of Tenant on which any lien is or can be validly and legally asserted against its leasehold interest in the Premises or the
improvements thereon and that it will save and hold Landlord harmless from any and all loss, cost or expense based on or arising out of asserted claims or liens against the leasehold estate or against the right, title and interest of Landlord in the
Premises or under the terms of this Lease. 
 12.     Assignment and Subletting. Tenant may assign this
Lease in its entirety or sublease all or any portion of the Premises without the consent of Landlord to (i) any entity resulting from a merger or consolidation with Tenant, (ii) any entity succeeding to all or substantially all of the
business and assets of Tenant, or (iii) any company or professional corporation or association affiliated with, owned by, or under common corporate control with Tenant (each a “Permitted Transferee”); provided, however, that the
financial capacity of the Permitted Transferee must be at least equal to that of the Tenant on the date of transfer and the transfer must not be effected by Tenant as a sham transaction or a means to circumvent the intent of this Section or
adversely affect the liability of Tenant hereunder. Except as herein otherwise provided, Tenant may not assign or encumber this Lease or its interest in the Premises arising under this Lease, and may not sublet any part or all of the Premises
without the prior consent of Landlord, which consent Landlord will not unreasonably withhold, or delay. For the purpose of the preceding sentence, the word “assign” will be defined and deemed to include the sale or other transfer of a
controlling percentage (hereafter defined) of capital stock of Tenant other than to an affiliate or subsidiary or the sale of at least fifty-one percent (51%) of the value of the assets of Tenant. The phrase
“controlling percentage” means the ownership of, and the right to vote, stock possessing at least fifty-one percent (51%) of the total combined voting power of all classes of Tenant’s capital
stock issued, outstanding and entitled to vote for the election of directors, or such lesser percentage as is required to provide actual control over the affairs of the corporation. Acceptance of Rent by Landlord after any non-permitted assignment will not constitute approval thereof by Landlord. Notwithstanding any contrary provision contained herein, in no event will any assignment by Tenant of all or any interest in this Lease or
any subletting of all or any part of the Premises result in Tenant being released from its obligations hereunder. 

  
 17 

 In no event will this Lease be assignable by operation of any law except as provided herein,
and Tenant’s rights hereunder may not become, and will not be listed by Tenant as an asset under any bankruptcy, insolvency or reorganization proceedings. Tenant is not, may not become, and will never represent itself to be an agent of
Landlord, and Tenant acknowledges that Landlord’s title is paramount, and that it can do nothing to affect or impair Landlord’s title. 

If this Lease will be assigned or the Premises or any portion thereof sublet by Tenant at a rental that exceeds the rentals to be paid to
Landlord hereunder, then sixty-five percent (65%) of such excess (after reduction for any expenses incurred by Tenant in conjunction with such assignment or subletting) will be due to the Landlord, upon actual receipt by Tenant. 

If Tenant desires to enter into any sublease of all or any portion of the Premises or assign its interest in this Lease, Landlord will have
the option to exclude from the Premises the space proposed to be sublet by Tenant or if an assignment is proposed, the entire Premises. Such exclusion or recapture by Landlord will be effective as of the proposed commencement date of the sublease or
assignment. Landlord may exercise said option by giving Tenant written notice within ten (10) business days after receipt by Landlord of Tenant’s request for consent to the proposed sublease or assignment. If Landlord exercises said
option, Tenant will surrender possession of such space to Landlord on the effective date of exclusion or recapture of such space and neither party hereto will have any future rights or liabilities with respect to said space under this Lease.
Effective as of the date of exclusion of any portion of the Premises covered by this Lease pursuant to this paragraph, (i) the Base Annual Rent will be reduced in the same proportion as the number of square feet of Net Rentable Area contained
in the portion of the Premises so excluded bears to the number of square feet of Net Rentable Area contained in the Premises immediately prior to such exclusion, and (ii) the Net Rentable Area of the Premises will be decreased by the number of
square feet of Net Rentable Area contained in the portion of the Premises so excluded, for all purposes under this Lease. 
 Landlord and
Tenant acknowledge and agree that the foregoing provisions have been freely negotiated by the parties hereto and that Landlord would not have entered into this Lease without Tenant’s consent to the terms of this Section. 

13.        Insurance. Landlord agrees to maintain standard fire and extended
coverage insurance for the Building (including the Tenant Improvements) in an amount not less than the replacement cost, insuring against special causes of loss, including, the perils of fire, and lightning, such coverages and endorsements to be as
defined, provided and limited in the standard bureau forms prescribed by the insurance regulatory authority for the State of North Carolina. Subject to the provisions of this Lease, such insurance will be for the sole benefit of Landlord and under
its sole control. 
 If the Premises should be damaged or destroyed by any peril covered by the insurance to be provided by Landlord
according to this section, Tenant will give prompt written notice thereof to 

  
 18 

 
Landlord. This Lease will not terminate (except as specifically provided herein), and Landlord will, at its sole cost and expense, thereupon proceed with reasonable diligence to rebuild and
repair the Premises to substantially the condition in which they existed prior to such damage, except that Landlord will not be required to rebuild, repair or replace any part of the partitions, fixtures, additions and other improvements which may
have been placed in, on or about the Premises by Tenant (other than the Tenant Improvements). If the Premises are untenantable for the normal conduct of Tenant’s business in whole or in part following such damage, the rent payable hereunder
during the period in which they are untenantable will be reduced proportionately. If such repair work is not completed within one hundred eighty (180) days of such casualty, and provided there is no default or event of default hereunder by
Tenant (or if Tenant has committed a default or event of default more than one (1) time in any twelve (12) month period, then regardless of whether same has been cured), then Tenant shall have the right to terminate this Lease upon written
notice to Landlord (prior to actual completion of said work). 
 Landlord shall maintain contractual and comprehensive general liability
insurance, including public liability and property damage, with a minimum combined single limit of liability of two million dollars ($2,000,000.00) for personal injuries or deaths of persons occurring in or about the Building and Premises. 

Notwithstanding anything herein to the contrary, in the event the holder of any indebtedness secured by a mortgage or deed of trust covering
the Premises requires that the insurance proceeds be applied to such indebtedness, and Landlord is unable to rebuild as confirmed by Landlord in writing to Tenant, then either Landlord or Tenant will have the right to terminate this Lease by
delivering written notice of termination to the other party within fifteen (15) days after such requirement is made by any such holder, whereupon all rights and obligations hereunder thereafter accruing will cease and terminate. 

Each of Landlord and Tenant hereby waives all rights to recover against each other or against any other tenant or occupant of the Building, or
against the officers, directors, shareholders, partners, joint venturers, employees, agents, customers, invitees, or business visitors of each other or of any other tenant or occupant of the Building, for any loss or damage arising from any cause
covered by any insurance required to be carried by each of them pursuant to this Lease, or any other insurance actually carried by either of them. Landlord and Tenant will cause their respective insurers to issue waiver of subrogation rights
endorsements to all policies of insurance carried in connection with the Building or the Premises or the contents of either of them, and any cost for the issuance of such endorsements will be borne by the original insured under such policies. 

The obligation of Landlord in this Section to repair and restore the Premises and the Building as provided herein, does not include an
obligation of Landlord to repair the fixtures, equipment, or personal property of Tenant, which Tenant will insure for its benefit, and Tenant will have the obligation to repair and restore in the event of a casualty or other loss. 

The period of time within which repair and restoration of the Premises must be completed will be extended due to delays occasioned by Force
Majeure. 

  
 19 

 Tenant will procure and maintain, at its expense, (i) special form property insurance
insuring against special causes of loss covering Tenant’s personal property, equipment, trade fixtures and any improvements performed by Tenant (specifically excluding the Tenant Improvements) in the Premises; and (ii) a policy or policies
of commercial general liability insurance applying to Tenant’s operations and use of the Premises, providing a minimum limit of $1,000,000.00 per occurrence and $2,000,000.00 in the aggregate, naming Landlord and Landlord’s property
manager as additional insureds. Tenant will maintain the foregoing insurance coverages in effect commencing on the earlier to occur of the Commencement Date and the date Tenant takes possession of the Premises, and continuing to the end of the Lease
Term. 
 The insurance requirements set forth in this Section are independent of the waiver, indemnification, and other obligations under
this Lease and will not be construed or interpreted in any way to restrict, limit or modify the waiver, indemnification and other obligations or to in any way limit any party’s liability under this Lease. In addition to the requirements set
forth in this section, (i) the insurance required of Tenant under this Lease must be issued by an insurance company with a rating of no less than A-VIII in the current Best’s Insurance Guide or that
is otherwise reasonably acceptable to Landlord, and (ii) the company issuing the coverage must be authorized to conduct the business of insurance in the state in which the Building is located; (iii) the insurance must be primary insurance
for all claims thereunder and provide that any liability insurance carried by Landlord, Landlord’s property manager, and Landlord’s lenders is strictly excess, secondary, and noncontributing with any insurance carried by Tenant;
(iv) Tenant must insure that its insurance company shall endeavor to provide at least thirty (30) days prior written notice of cancellation or non-renewal of a policy to Landlord and Landlord’s
lenders; and (v) Tenant shall provide Landlord a copy of any notice of cancellation or non-renewal of a policy immediately upon receipt by Tenant. Tenant will deliver to Landlord a legally enforceable
certificate of insurance on all policies procured by Tenant in compliance with Tenant’s obligations under this Lease on or before the date Tenant first occupies any portion of the Premises, at least ten (10) days before the
expiration date of any policy and upon the renewal of any policy. Landlord will have the right to approve all deductibles and self-insured retentions under Tenant’s policies, which approval will not be unreasonably withheld, or delayed.

 14.    Condemnation. If the whole or any substantial portion of the Premises should be taken for any
public or quasi-public use under governmental law, ordinance, or regulation, or by right of eminent domain, or by private purchase in lieu thereof, and the taking would prevent or materially interfere with the use of the Premises by Tenant for the
purposes provided herein as mutually and reasonably determined by Landlord and Tenant, each party hereto will have the right to terminate this Lease by notice to the other party hereto within forty-five (45) days after the date of such taking
and the Rent will be abated during the unexpired portion of this Lease, effective when the physical taking of the Premises will occur. If this Lease is not terminated in accordance with the foregoing, this Lease will remain in full force and effect
as to the portion of the Premises remaining, except that the Rent will be reduced in the proportion that the taken floor area of the Premises bears to the total floor area of the Premises as reasonably determined by Landlord. 

If a portion of the Premises will be taken for any public or quasi-public use under any governmental law, ordinance or regulation, or by right
of eminent domain, or by private purchase in lieu thereof, and there is no material interference with the use by Tenant of the Premises as reasonably determined, this Lease will remain in full force and effect as to the portion of the Premises
remaining, except that the Rent will be reduced in the proportion that the taken floor area of the Premises bears to the total floor area of the Premises. 

  
 20 

 In the event of any such taking or private purchase in lieu thereof, Landlord will be
entitled to receive and retain all awards as may be awarded in any condemnation proceedings with Tenant hereby expressly waiving all claim thereto other than those specifically awarded Tenant for a taking of Tenant’s personal property, loss of
business and moving expenses. 
 15.    Default. The following events will be deemed to be events of
default by Tenant under this Lease: 
 (a) Tenant will fail to pay any installment of the Rent herein reserved, or payment with respect to
taxes hereunder, or any other payment or reimbursement to Landlord required herein, within five (5) days of when due; provided, however, on one occasion during each calendar year of the term of this Lease, it shall not be an event of default
hereunder if Tenant makes full payment within five (5) days after receipt of written notice from Landlord. 
 (b) Tenant will become
insolvent, or will make a transfer in fraud of creditors, or will make an assignment for the benefit of creditors. 
 (c) Tenant will file a
petition under any section or chapter of the Bankruptcy Reform Act, as amended or under any similar law or statute of the United States or any state thereof; or Tenant will be adjudged bankrupt or insolvent in proceedings filed against Tenant
thereunder. 
 (d) A receiver or trustee will be appointed for all or substantially all of the assets of Tenant. 

(e) Tenant will desert or vacate all or a portion of the Premises, and cease paying Rent at the Premises. 

(f) Tenant will fail to yield up immediate possession of the Premises to Landlord upon termination of this Lease. 

(g) Tenant will fail to comply with any term, provision or covenant of this Lease (other than the provisions of subparagraphs (a), (b), (c),
(d), (e) and (f) of this Section 15), and will not cure such failure within thirty (30) days after written notice thereof to Tenant or such additional period of time as will be reasonably granted by Landlord if Tenant is acting in
good faith and with diligence to complete such cure. 
 Upon the occurrence of any event of default in the preceding section hereof,
Landlord will have the option to pursue any remedy at law or in equity, including, but not limited to, one or more of the following remedies without any separate notice or demand whatsoever: 

(a) Terminate this Lease, in which event Tenant will immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord
may, without prejudice to any other remedy which it may have for possession or arrearage in Rent, enter upon and take possession of the Premises and expel and remove Tenant and any other person who may be occupying the Premises or any part thereof,
by any legal means necessary without being liable for prosecution or any claim of damages therefore; secure the Premises against unauthorized entry; and Tenant agrees to pay to Landlord on demand the amount of all loss and damage which Landlord may
suffer by reason of such termination, whether through inability to relet the Premises on satisfactory terms or otherwise. 

  
 21 

 (b) Enter upon and take possession of the Premises and expel or remove Tenant and any other
person who may be occupying such Premises or any part thereof, by any legal means necessary without being liable for prosecution and receive the Rent thereof; secure the Premises against unauthorized entry; store any property located on the Premises
at the expense of the owner thereof and Tenant agrees to pay to Landlord on demand any deficiency that may arise by reason of such reletting. In the event Landlord is successful in reletting the Premises at a rental in excess of that agreed to be
paid by Tenant pursuant to the terms of this Lease, Landlord and Tenant each mutually agree that Tenant will not be entitled, under any circumstances, to such excess rental, and Tenant does hereby specifically waive any claim to such excess rental.

 (c) Enter upon the Premises, by any legal means necessary without being liable for prosecution or any claim for damages therefore, secure
the Premises against unauthorized entry, remove all property of Tenant from the Premises and store it at the cost and expense of Tenant, and do whatever Tenant is obligated to do under the terms of this Lease; and Tenant agrees to reimburse Landlord
on demand for any expenses which Landlord may incur in thus effecting compliance with Tenant’s obligations under this Lease, and Tenant further agrees that Landlord will not be liable for any damages resulting to Tenant from such action,
whether caused by the negligence of Landlord or otherwise. 
 (d) Subject to the obligation of Landlord to mitigate its damages under
Applicable Law, accelerate and demand the payment of all Rent and other charges due and payable hereunder over the term of this Lease to an amount equal to the aggregate sum which at the time of such termination represents the excess, if any, of the
present value of the aggregate Rent which would have been payable after the termination date had this Lease not been terminated, including, without limitation, the amount projected by Landlord as Rent for the remainder of the Lease Term, over the
then present value of the then aggregate fair rent value of the Premises for the balance of the Lease Term, such present worth to be computed in each case on the basis of the lesser of: (i) the rate on a United States Treasury bill with a
maturity date equal to the termination date of the Lease, or (ii) five percent (5%) per annum discount from the respective dates upon which such Rent would have been payable hereunder had this Lease not been terminated. 

Landlord’s failure to perform or observe any of its Lease obligations after a period of thirty (30) days or the additional time, if
any, that is reasonably necessary to promptly and diligently cure the failure after receiving written notice from Tenant is a Landlord Default. The notice shall reasonably detail the nature and extent of the failure and identify the Lease
provision(s) containing the obligation(s). If Landlord commits a Landlord Default, Tenant may pursue any remedies given in this Lease or under Applicable Law. 

Pursuit of any of the foregoing remedies will not preclude pursuit of any of the other remedies herein provided or any other remedies provided
by law or equity, nor will pursuit of any remedy herein provided constitute a forfeiture or waiver of any Rent due to Landlord hereunder or of any damages accruing to Landlord by reason of the violation of any of the terms, provisions and covenants
herein contained. No act or thing done by Landlord or its agents during the term hereby granted will be deemed a termination of this Lease or an acceptance of the surrender of the Premises, and no agreement to terminate this Lease or accept a
surrender 

  
 22 

 
of the Premises will be valid unless in writing signed by Landlord. No waiver by Landlord or Tenant of any violation or breach of any of the terms, provisions and covenants herein contained will
be deemed or construed to constitute a waiver of any other violation or breach of any of the terms, provisions and covenants herein contained. Landlord’s acceptance of the payment of rental or other payments hereunder after the occurrence of an
event of default will not be construed as a waiver of such default, unless Landlord so notifies Tenant in writing, and no receipt of money by Landlord from Tenant after the termination of this Lease or after service of any notice or after the
commencement of any suit or after final judgment for possession of the Premises will reinstate, continue or extend the term of this Lease or affect any such termination, notice, suit or judgment, unless Landlord so notifies Tenant in writing.
Forbearance by Landlord or Tenant to enforce one or more of the remedies herein provided upon an event of default will not be deemed or construed to constitute waiver of such default or of said party’s right to enforce any such remedies with
respect to such default or any subsequent default. 
 Notwithstanding any provision contained in this Lease to the contrary, should either
party institute any legal proceeding against the other for breach of any provision herein contained and prevail in such action, such other party shall reimburse the prevailing party for the expenses of such prevailing party, including, without
limitation, its reasonable attorneys’ fees actually incurred at standard and reasonable billing rates. 

16.    Holding Over and Termination. Tenant will upon the termination of this Lease by lapse of time or
otherwise, yield up immediate possession to Landlord without the requirement of notice by Landlord to Tenant of the termination of this Lease, nor any grace or cure period should Tenant fail to yield up immediate possession to Landlord. Unless the
parties hereto will otherwise agree in writing, if Landlord agrees in writing that Tenant may hold over after the expiration or termination of this Lease, the hold over tenancy will be subject to termination by Landlord at any time upon thirty
(30) days advance written notice, or by Tenant at any time upon not less than thirty (30) days advance written notice, and all of the other terms and provisions of this Lease will be applicable during that period, except that Tenant will
pay Landlord from time to time upon demand, as rental for the period of any hold over, an amount equal to one and one-half (1-1/2) the Base Annual Rent plus Additional
Rent in effect on the Termination Date, computed on a daily basis for each day of the hold over period. No holding over by Tenant, whether with or without consent of Landlord, will operate to extend this Lease except as otherwise expressly provided.
The preceding provisions of this Section 16 will not be construed as Landlord’s consent for Tenant to hold over. 
 Upon the
termination of this Lease for whatever reason, Tenant will quit and immediately surrender the Premises to Landlord, broom clean, in as good order and condition as received with all repairs and maintenance required by Tenant hereunder having been
performed, ordinary wear and tear excepted, and Tenant will remove its personal property from the Premises in accordance with this Lease. Should any of the personal property or trade fixtures of Tenant remain upon the Premises after the Termination
Date, all such property will be deemed abandoned by Tenant, and Landlord may remove same at the cost and expense of Tenant with no liability to Tenant therefore, and Tenant hereby releases Landlord from all liability therefore. 

  
 23 

 17.    Compliance with Laws. The Premises will be used
only for the Permitted Use. Landlord acknowledges that Tenant will be using the Premises as a laboratory for a biotechnology company and is aware that with respect to such usage, Tenant may bring a
pre-approved list of Hazardous Materials onto the Premises. Tenant will conduct no activity that will result in the discharge of harmful gases, effluents or other wastes or toxic substances beyond the Premises
or in violation of Applicable Laws. Outside storage, including, without limitation, trucks and other vehicles, is prohibited without Landlord’s prior written consent. Tenant will at its sole cost and expense obtain any and all licenses and
permits necessary for its use of the Premises. Tenant will promptly comply with all governmental orders and directives for the correction, prevention, and abatement of nuisances connected with or arising from Tenant’s use of the Premises, all
at Tenant’s sole expense. During the Term, Landlord shall comply with all Applicable Laws regarding the Premises and Building, except to the extent Tenant must comply under this Section 17. Except as to
pre-existing defects, violations or conditions, Tenant shall comply with all Applicable Laws: (i) regarding the physical condition of the Premises, but only to the extent the Applicable Laws pertain to
the particular manner in which Tenant uses the Premises; or (ii) that do not relate to the physical condition of the Premises but relate to the lawful use of the Premises and with which only the occupant can comply, such as laws governing
maximum occupancy, workplace smoking, and illegal business operations, such as gambling. Tenant will not permit any objectionable or unpleasant odors, smoke, dust, gas, noise or vibrations to emanate from the Premises, nor take any other action
which would constitute a nuisance, disturb or endanger any other tenants of the Building, or unreasonably interfere with the quiet enjoyment by any tenant of the Building. Without Landlord’s prior written consent (not to be unreasonably
withheld, or delayed), Tenant will not receive, store or otherwise handle any product, material or merchandise which is explosive, inflammable, combustible, corrosive, caustic or poisonous (except as provided herein). Tenant will not permit the
Premises to be used for any purpose or in any manner (including, without limitation, any method of storage) which would render the insurance thereon void or the insurance risk more hazardous or cause the State Board of Insurance or other insurance
authority to disallow any sprinkler credits. Tenant will give notice to Landlord promptly upon the known occurrence of any accident in the Premises or upon Tenant’s discovery of any defects thereon or in any fixtures or equipment located
therein or upon the occurrence of any emergency in the Premises, Building, or Project. Tenant will be permitted to use and store at the Premises in compliance with Hazardous Material Laws and the provisions hereof commercially reasonable quantities
of (i) generally available standard office and janitorial supplies that may contain chemicals categorized as Hazardous Material, and (ii) such other substances that are required in the ordinary course of Tenant’s business conducted on
the Premises. Tenant, at its expense, in its use of the Premises and in making any alterations, renovations, or modifications of the Premises will comply with all Applicable Laws relating to the use, condition and occupancy of the Premises. 

Tenant agrees that it will not release, discharge, place, hold, or dispose of any Hazardous Material on, under or at the Premises, in the
Building, or on the Land, and that it will not use the Premises, the Building, the Land, or any other portion thereof as a site for the treatment, storage (except in accordance with this Section 17), or disposal (whether permanent or temporary)
of any Hazardous Material. Tenant further agrees that it will not cause or allow any asbestos to be incorporated into any improvements or alterations which Tenant makes or causes to be made to the Premises, or the Building. 

  
 24 

 Tenant hereby agrees to indemnify, defend (with counsel reasonably approved by Landlord) and
hold harmless Landlord of from and against any and all losses, liabilities, damages, injuries, costs, expenses and claims of any and every kind whatsoever (including without limitation, court costs and attorneys’ fees at all tribunal levels)
which at any time and from time to time may be paid, incurred or suffered by, or asserted against Landlord for, with respect to, or as a direct or indirect result of any breach or default by Tenant of the provisions of this Section 17. The
provisions of and undertakings and indemnification set forth in this Section will survive the termination or expiration of this Lease, for any reason, and will continue to be the liability, obligation and indemnification of Tenant, binding upon
Tenant forever. The provisions of the preceding sentence will govern and control over any inconsistent provision of this Lease. 
 Tenant
will provide Landlord with a list of any and all Hazardous Materials released, discharged, placed, held, or disposed of on the Premises, and certification to Landlord of compliance by Tenant with all Applicable Laws, concurrently with the execution
of this Lease which shall be attached hereto and made a part as Exhibit G, and thereafter, within ten (10) business days of a request therefore by Landlord (which Landlord shall not request more than four times in any calendar year). 

Landlord hereby represents and warrants, to the best of Landlord’s actual knowledge, that no Hazardous Materials exist on, under, in or
about the Premises as of the Commencement Date except as disclosed in the Phase I Environmental Site Assessment obtained by Landlord for the Building (the “Report”). Tenant shall have the right to review the Report at the offices of
Landlord upon written notice to the Landlord. Landlord shall indemnify, defend and hold harmless Tenant from and against any and all Claims which at any time and from time to time may be paid, incurred or suffered by or assessed against Tenant as a
direct or indirect result of the presence of any Hazardous Materials in, on or under the Premises, Building or Project prior to the Commencement Date or after the termination of this Lease so long as such presence was not due to an act or omission
of Tenant or a Tenant Party. 
 18.    Inspection. Landlord and Landlord’s agents and representatives
will have the right to enter and inspect the Premises at any reasonable time during business hours, for the purpose of ascertaining the condition of the Premises, in order to make such repairs as may be required or permitted to be made by Landlord
to the Building or any adjacent space, under the terms of this Lease, or in order to show the Premises to any prospective purchaser or lender; provided that (i) except in the case of an emergency, Landlord has given Tenant a written or verbal
notice of the intent to enter at least two (2) business days in advance of the entry, (ii) such entry and any related inspection or repairs do not unreasonably interfere with Tenant’s business operations, (iii) Landlord complies
with Tenant’s reasonable security measures and protocols which are detailed on Exhibit F (as Tenant shall be entitled to reasonably update), attached hereto, and Tenant provides Landlord protective gear, and (iv) Landlord is accompanied by
a representative of Tenant at all times, except in an emergency. During the period that is six (6) months prior to the end of the term hereof (and subject to the same access caveats listed above),

  
 25 

 
Landlord and Landlord’s agents and representatives will have the right to enter the Premises at any reasonable time during business hours for the purpose of showing the Premises to any
prospective tenant and will have the right to erect on the Premises a suitable sign indicating the Premises are available. Tenant will schedule with Landlord (at Landlord’s request) at least sixty (60) days prior to vacating the Premises a
time mutually agreeable to the parties hereto for a joint inspection of the Premises prior to vacating. In the event of Tenant’s failure to reasonably arrange such joint inspection, Landlord’s inspection at or after Tenant’s vacating
the Premises will be conclusively deemed correct for purposes of determining Tenant’s responsibilities for repairs and restoration. 

19.    Tenant Property. Upon reasonable request, so long as Tenant is not in default under this Lease,
Landlord agrees to execute, within twenty (20) days following written request, any commercially reasonable document reflecting the subordination of any such Landlord’s interest to Tenant’s lender(s) and in such event Tenant shall pay
Landlord’s reasonable and actual “out-of-pocket” costs therefore. 

20.    [INTENTIONALLY DELETED.] 

21.    Rules and Regulations. Tenant, at its expense, will comply with the Rules and Regulations of the
Building attached hereto and made a part hereof as Exhibit E, as reasonably modified by Landlord from time to time and such other Rules and Regulations adopted by Landlord during the Lease Term and Tenant will use all commercially reasonable
efforts to cause all Tenant Parties to do so. Provided, however, that (a) such rules and regulations do not increase the Rent payable hereunder; (b) such rules and regulations do not unreasonably and materially interfere with Tenant’s
conduct of its business or Tenant’s use and enjoyment of the Premises for the Permitted Use; (c) Landlord provides reasonable advance written notice thereof; and (d) such rules and regulations are uniformly enforced in a non-discriminatory manner. All such additions or changes to Rules and Regulations will be sent by Landlord to Tenant in writing and shall become effective ten (10) days thereafter. In the event of a conflict
between the rules and regulations and the terms of this Lease, the terms of this Lease will control. 

22.    Assignments by Landlord. Landlord will have the right to transfer and assign, in whole
or in part, all its rights and obligations hereunder and in the Building and Project, and in such event and upon its transferee’s assumption of Landlord’s obligations thereafter accruing hereunder, no further liability or obligation will
thereafter accrue against Landlord hereunder (provided that any such successor in interest expressly assumes the obligations of Landlord hereunder, in writing). Upon request by Landlord, Tenant agrees to execute a certificate certifying such facts
as Landlord may reasonably require in connection with any such assignment by Landlord. This paragraph shall not affect Landlord’s liability for matters arising prior to the transfer of the Building including the Security Deposit. 

23.    Quiet Enjoyment. Landlord represents and warrants that it has full right and authority to enter into
this Lease and that Tenant, upon paying the rental herein set forth and performing its other covenants and agreements herein set forth, will peaceably and quietly have, hold and enjoy the Premises for the term hereof without hindrance or molestation
from Landlord or any other lawful claimant to ownership or possession of the Premises, subject to the terms and provisions of this Lease. 

  
 26 

 24.    Liability. Tenant specifically agrees to look
solely to Landlord’s (or its successors’) interest in the Building (including rental income and insurance/condemnation proceeds) for the recovery of any judgment (or other judicial decree) from Landlord. Landlord (or if Landlord is a
limited liability company, its members, or if Landlord is a corporation, its directors, officers or any successors in interest) shall never be personally liable for any such judgment. In no event shall Landlord be liable under this Lease for any
consequential or punitive damages except to the extent caused by the gross negligence or willful misconduct of Landlord. This exculpation of liability to be absolute and without exception whatsoever. 

Landlord will not be liable to Tenant or any Tenant Party, or to any other person whomsoever, for any damage to property on or about the
Premises belonging to Tenant or any other person, due to any cause whatsoever, unless caused by the gross negligence or willful or intentional misconduct of Landlord. 

Tenant hereby covenants and agrees that it will at all times indemnify, defend (with counsel reasonably approved by Landlord) and hold safe
and harmless Landlord (including, without limitation, its trustees and beneficiaries if Landlord is a trust), and the Landlord Parties from any loss, liability, claims, suits, costs, expenses, including without limitation reasonable attorney’s
fees and damages, both real and alleged, incurred by Landlord or a Landlord Party arising out of or resulting from the negligence or misconduct of Tenant, a breach by Tenant of any provision of this Lease, or the conduct by Tenant of its business in
the Building. 
 Landlord hereby covenants and agrees that it will at all times indemnify, defend (with counsel reasonably approved by
Tenant) and hold safe and harmless Tenant, and the Tenant Parties from any loss, liability, claims, suits, costs, expenses, including without limitation reasonable attorney’s fees and damages, both real and alleged, incurred by Tenant or a
Tenant Party arising out of or resulting from the operation by Landlord of the Building, the negligence or misconduct of Landlord, or a breach by Landlord of any provision of this Lease. 

25.    Mortgages. Tenant accepts this Lease subject and subordinate to any mortgage(s) and/or deed(s) of
trust now or at any time hereafter constituting a lien or charge upon the Premises or the improvements situated thereon; provided, however, that if the mortgagee, trustee, or holder of any such mortgage or deed of trust elects to have Tenant’s
interest in this Lease superior to any such instrument, then by notice to Tenant from such mortgagee, trustee or holder, this Lease will be deemed superior to such lien, whether this Lease was executed before or after said mortgage or deed of trust.
Tenant will at any time hereafter on demand execute and provide to Landlord within ten (10) business days of a request therefore, any commercially reasonable instruments, releases or other documents which may be reasonably required by any
mortgagee or trustee for the purpose of further subjecting and subordinating this Lease to the lien of any such mortgage or deed to trust in form and substance as reasonably required by such mortgagee or trustee. Notwithstanding the foregoing, it
shall be a condition precedent to any subordination that Tenant be provided with a written non-disturbance agreement in the form stipulated by Landlord’s lender (provided that: (i) Tenant shall be
entitled to request of 

  
 27 

 
Landlord’s lender commercially reasonable revisions to said form at its cost which costs include payment of any attorneys’ fees charged to Landlord by Landlord’s lender (as
reasonably documented by Landlord); and (ii) said form provides that, if the holder of any mortgage or deed of trust shall take title to the Premises through foreclosure or deed in lieu of foreclosure or otherwise, Tenant shall be allowed to
continue in possession of the Premises as provided in this Lease so long as Tenant is not in default, beyond any applicable cure period). 

26.     Signs. Tenant will not be permitted any signage visible from outside of its Premises which has not
been approved in writing in advance by Landlord in its reasonable discretion. The cost of or related to any approved signage will be entirely at Tenant’s own expense, and all such signage shall be removed by Tenant, at its cost at the end of
the term and any damage due to such removal repaired by Tenant prior to vacating the Premises. Landlord shall provide at its expense signage on the entry door to the Premises, and signage on the directory for the Building. Landlord shall provide
Tenant its exterior signage criteria prior to the execution of this Lease. 

27.        Keys and Locks. Landlord, at its expense, shall provide Tenant with
forty (40) card keys for access to the Building. Landlord acknowledges that Tenant shall have the right to install its own access control system to the Premises and Tenant shall furnish and provide Landlord with duplicate keys and/or access
cards, as applicable, to ensure that Landlord and its representatives can gain access to the Premises when permitted by the terms of this Lease. Upon termination of this Lease, Tenant shall surrender to Landlord all keys to the Premises and give to
Landlord the combination of all locks for safes, safe cabinets and vault doors, if any, remaining in the Premises. 

28.    Brokers. Landlord acknowledges that Cassidy Turley (and its successors and assigns) is acting
as the sole agent for Tenant in this transaction and shall be paid a brokerage fee by Landlord pursuant to a separate agreement with Landlord. Tenant confirms that no broker other than Cassidy Turley is assisting Tenant in this matter. Landlord
confirms that no broker is assisting Landlord in this matter. Landlord and Tenant covenant to pay, hold harmless and indemnify the other from and against any and all costs, expenses or liability for any compensation, commissions and charges claimed
by any other broker or agent, with respect to the transactions contemplated hereby or the negotiation thereof and arising by virtue of the acts of the indemnifying party. 

29.    Notices. Each provision of this instrument or of any Applicable Law with reference to the sending,
mailing, or delivery of any notice by either party, or with reference to the making of any payment by Tenant to Landlord will be deemed to be complied with when and if the following steps are taken: 

(a)    All Rent and other payments required to be made by Tenant to Landlord hereunder will be payable to
Landlord at the address below or at such other address as Landlord may specify from time to time by written notice delivered in accordance herewith. Tenant’s obligations to pay Rent and any other amounts to Landlord under the terms of this
Lease will not be deemed satisfied until such Rent and other amounts have been actually received by Landlord. 

  
 28 

 (b)     Any notice or document required or permitted to
be delivered hereunder will be deemed to be delivered upon actual receipt or refusal thereof, and shall be: (i) sent by standard, commercial overnight delivery service, such as Federal Express, or (ii) sent by Certified or Registered Mail,
return receipt requested, postage prepaid, and addressed to the parties hereto at the respective addresses set out below, or at other such addresses as they have heretofore specified by written notice delivered in accordance therewith.

(a)    Words of any gender used in this Lease will be held and construed to include any other gender, and words in the
singular number will be held to include the plural, unless the context otherwise requires. 
 (b)    The terms,
provisions and covenants and conditions contained in this Lease will 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 herein expressly provided. Landlord will have the right to assign any of its rights and obligations under this Lease. Each party agrees to furnish to the other, promptly upon demand, a resolution, or other appropriate documentation
evidencing the due authorization of such party to enter into this Lease. 

  
 29 

 (c)    The captions inserted in this Lease are for convenience only and
in no way define, limit or otherwise describe the scope or intent of this Lease, or any provision hereof, or in any way affect the interpretation of this Lease. 

(d)    Tenant agrees from time to time, within ten (10) business days after request of Landlord, to deliver to
Landlord, or Landlord’s designee, an estoppel certificate stating, to the extent true and to Tenant’s actual knowledge, that this Lease is in full force and effect, the date to which Rent has been paid, the unexpired term of this Lease and
such other matters pertaining to this Lease as may be reasonably requested by Landlord. It is understood and agreed that Tenant’s obligation to furnish such estoppel certificates in a timely fashion is a material inducement for Landlord’s
execution of this Lease. 
 (e)    This Lease may not be altered, changed or amended except by an instrument in writing
signed by both parties hereto. 
 (f)    All obligations of Landlord and Tenant hereunder not fully performed as of the
expiration or earlier termination of the term of this Lease will survive the expiration or earlier termination of the term hereof, including, without limitation, all payment obligations concerning the condition of the Premises and all obligations of
Tenant as provided in Section 5 hereof. 
 (g)    In the case of a foreclosure or deed in lieu of foreclosure on a
mortgage or deed of trust existing prior to the date of this Lease, in the event of a transfer by Landlord of its interest in the Premises, Landlord will be released from all obligations and liabilities under the terms of this Lease arising
subsequent to the date of such transfer. In the event a transferee will agree to assume the obligations and liabilities of Landlord under the Lease prior to the date of the transfer, Landlord will be released from all obligations and liabilities
under the Lease. 
 (h)    If any clause or provision of this Lease is illegal, invalid or unenforceable under present or
future laws effective during the term of this Lease, then and in that event, it is the intention of the parties hereto that the remainder of this Lease will not be affected thereby, and it is also the intention of the parties to this Lease that in
lieu of each clause or provision of this Lease that is illegal, invalid or unenforceable, there be added as a part of this Lease a clause or provision as similar in terms to such illegal, invalid or unenforceable clause or provision as may be
possible and be legal, valid and enforceable. 
 (i)    Because the Premises are on the open market and are presently
being shown, this Lease will be treated as an offer with the Premises being subject to prior lease and such offer subject to the withdrawal or non-acceptance by Landlord or to other use of the Premises without
notice, and this Lease will not be valid or binding unless and until accepted by Landlord in writing and a fully executed copy delivered to both parties hereto. 

(j)    All references in this Lease to “the date hereof” or similar references will be deemed to refer to the
last date, in point of time, on which all parties hereto have executed this Lease. 
 (k)    Time is of the essence of
this Lease. 
 (l)    Landlord will not be in default in the performance of any of Landlord’s obligations hereunder
unless and until Landlord will have failed to perform such duties or obligations within thirty (30) days (or such additional time as is reasonably required to correct any such default) after written notice by Tenant to Landlord properly
specifying wherein Landlord has failed to perform any such duty or obligation. In cases where there is an imminent threat of harm to person or property at the Premises, or if Tenant cannot conduct its business at the Premises, Landlord shall effect
a cure within a reasonable period of time using all reasonable efforts. Should a cure be required and Landlord fail to effect a cure within ten (10) business days after the date after receipt by Landlord from Tenant of written notice with
respect to such 

  
 30 

 
default, Tenant shall have the right to effect such cure. Except as expressly provided in this Lease to the contrary, Landlord will have no liability for any incidental or consequential damages
of Tenant, or anyone claiming by, through or under Tenant, for any reason whatsoever. 
 (m)    This Lease does not
create the relationship of partner or joint venturer between Landlord and Tenant. 
 (n)    The laws of the State of
North Carolina will govern the interpretation, the validity, performance and enforcement of this Lease. 
 (o)    (i) If
Tenant is a corporation, the undersigned officer of Tenant does hereby warrant and certify to Landlord that Tenant is a corporation in good standing and duly organized under the laws of the State of North Carolina, or if chartered in a state other
than the State of North Carolina, is a corporation in good standing and duly organized under the laws of such state and is authorized to do business in the State of North Carolina. The undersigned officer of Tenant hereby further warrants and
certifies to Landlord that such officer is authorized and empowered to bind the corporation to the terms of this Lease by such officer’s signature hereto; (ii) If Tenant is a general or limited partnership, the undersigned general partner
of Tenant does hereby warrant and certify to Landlord that Tenant is a general partnership or limited partnership, as the case may be, validly existing under the laws of the State of North Carolina, or if formed in a state other than the State of
North Carolina, is a general partnership or limited partnership validly existing under the laws of such state and is authorized to do business in the State of North Carolina. The undersigned general partner of Tenant hereby further warrants and
certifies to Landlord that such general partner is authorized and empowered to bind Tenant to the terms of this Lease by such general partner’s signature hereto. (iii) Landlord confirms that those persons signing below on its behalf are
duly authorized to do so. 
 (p)    The provisions of any Exhibits referenced herein, whether or not attached hereto, are
incorporated herein by reference and made a part of this Lease. 
 (q)    Although the printed provisions of this Lease
were drafted by Landlord, such fact will not cause this Lease to be construed either for or against Landlord or Tenant. 

(r)    This Lease may not be recorded. Upon the request and at the expense of Tenant, Landlord will execute a memorandum of
this Lease suitable for recording which will omit the financial terms herein but which will identify the Premises, the Parties, and the term of this Lease. Upon the expiration of this Lease, a recorded memorandum of this Lease may be canceled of
record by a document executed by Landlord, or its successor in interest for such purpose. 
 (s)    Tenant will provide
to Landlord within ninety (90) days of the close of its fiscal year, and thereafter within ten (10 business days of the reasonable request of Landlord, but no more than once per calendar year except during any default or event of default by
Tenant when this limitation shall not apply, financial statements of Tenant (consisting of summarized profit and loss statement, balance sheet, and cash flow statement) certified by the chief financial officer of Tenant. 

(t)    No remedy conferred herein is intended to be exclusive of any other remedy and each and every remedy will be
cumulative and will be in addition to every other remedy given hereunder or thereunder or now or hereafter existing at law or in equity or by statute or otherwise. 

(u) [INTENTIONALLY DELETED.] 
 (v)
Tenant, its employees, and invitees shall have access to the Premises twenty-four (24) hours a day, seven (7) days a week. 

  
 31 

 (w)    The provisions of this Lease and any information regarding
Landlord, including its construction process, and the materials and standards used, will be maintained confidential by Tenant, its agents, employees, officers, and legal and tax advisors. 

(x)    Tenant shall be responsible for all ad valorem taxes on its personal property and on the value of the leasehold
improvements to the extent that such improvements do not constitute fixtures, or additions or improvements to real property (as reasonably documented by Landlord). Tenant, within thirty (30) days of receipt of an invoice, shall also pay to
Landlord all sales or use taxes or excise taxes imposed or levied by the State of North Carolina or any other governmental body or agency, if any, against any rent or any other charge or payment required hereunder to be made by Tenant to Landlord.

 (y) This Lease does not grant any rights to light, view or air over adjacent property, and any diminution or shutting off of light, view

 EXHIBIT D 

WORK LETTER 
 This Exhibit D sets forth
the rights and obligations of Landlord and Tenant with respect to the construction of the improvements to the Premises as described on the Plans (“Tenant Improvements”). This Exhibit contemplates that the following work will be performed,
as further described herein, all subject to the prior review and approval by Landlord: (i) preparation of a space plan by the Architect; (ii) final design and engineering and preparation of plans, specifications, and working drawings by
the Architect (collectively, the “Plans”); (iii) preparation by the general contractor of Landlord (the “General Contractor”) of an estimate of the cost of the Tenant Improvements; (iv) submission to, and approval of Plans
by, appropriate governmental authorities; and (v) construction and installation of the Tenant Improvements by the Landlord pursuant to the Plans on or prior to the Commencement Date, subject to Force Majeure and any Tenant Delay. 

1.    Allowance/Payment of Construction Costs. 

(a)    Landlord shall construct the Tenant Improvements in accordance with a milestone schedule (the “Schedule”),
a copy of which shall be provided to Tenant for Tenant’s reasonable approval prior to commencement of construction of the Tenant Improvements. Landlord and Tenant shall prepare and mutually and reasonably approve a budget (the
“Budget”) for the costs to construct the Tenant Improvements (the “Construction Costs”) which shall be attached hereto as Exhibit D-3. The Budget does not include any amounts for furniture, fixtures (other than lighting),
equipment, voice/data systems, or personal property of Tenant, which items will be paid for by Tenant separately at its expense. The Budget includes a Construction Contingency which shall be 5% of the Construction Costs. Any unspent Construction
Contingency will accrue to the Tenant. Change Orders (as hereinafter defined) shall be funded from increases in the Contract (as hereinafter defined). Landlord agrees to fund a portion of the Construction Costs through the provision of the Tenant
Improvement Allowance. The Tenant Improvement Allowance shall be used for items specifically outlined in the Budget and mutually agreed upon by both Landlord and Tenant. The Tenant Improvement Allowance shall be used only for construction, design,
and management costs related to fixed improvements to the Building that are part of the Tenant Improvements. The Tenant Improvement Allowance may not be used to offset any Rent payments owed to Landlord by Tenant. Any costs incurred due to a Tenant
Delay shall be charged against the Tenant Improvement Allowance; provided, however, Tenant shall be given two (2) days’ notice and opportunity to cure any Tenant Delay (including payment by Tenant of any costs associated with such cure
such as higher shipping charges) before any costs are charged against the Tenant Improvement Allowance. Landlord and Tenant acknowledge and agree that the Construction Costs will be in excess of the Tenant Improvement Allowance, and all costs for
the Tenant Improvements in excess of the Tenant Improvement Allowance shall be borne by Tenant. Therefore, Tenant has agreed to place into an escrow account maintained with Landlord (the “Escrow Account”) an amount equal to the
Construction Costs as specified in the Budget minus the Tenant Improvement Allowance (the “Tenant Improvement Overage”). Landlord shall 

  
 38 

 
establish the Escrow Account as a separate, interest bearing account in an FDIC insured institution. set forth below, Landlord shall have the authority to make periodic deductions from the Escrow
Account as payment for the Construction Costs and the Escrow Account shall be funded in full by Tenant prior to Landlord’s issuance of a Notice to Proceed to the General Contractor. Failure by Tenant to deposit the Tenant Improvement Overage
into the Escrow Account within five (5) business days after a request from Landlord hereunder shall be a Tenant Delay and a default in payment hereunder. Tenant shall receive all interest that accrues under the Escrow Account. 

(b) The Tenant Improvement Allowance and Tenant Improvement Overage shall be disbursed by Landlord upon satisfaction of the following
conditions precedent: (i) Landlord shall have received applications for payment certified by the Architect, accompanied by evidence of the portion of the Tenant Improvements that have been completed per the Plans, invoices and paid receipts for
all such work completed, and copies of executed lien waivers from those persons providing such work; and (ii) all information and documentation provided to Landlord must be in form and substance reasonably approved by Landlord. Upon
Tenant’s request, Landlord shall provide Tenant an opportunity to review such information and documentation. 

(c)    Provided the aforesaid conditions are met, Landlord shall pay the Construction Costs at monthly intervals based upon
design and construction billing cycles. Each monthly payment of the Construction Costs shall be paid as follows: fifty percent (50%) of such payment shall be paid from the Tenant Improvement Allowance and the remaining fifty percent (50%) of such
payment shall be paid from the Tenant Improvement Overage through the Escrow Account. Within thirty (30) days after the Commencement Date, Landlord shall prepare and submit to Tenant a final statement that illustrates the total cost to
construct the Tenant Improvements and the amount paid from and remaining with respect to each of the Tenant Improvement Overage as held in the Escrow Account, and the Tenant Improvement Allowance. If such statement indicates that Landlord has paid
less than the total amount of the Tenant Improvement Allowance, then Landlord shall pay Tenant an amount equal to the Tenant Improvement Allowance minus the total amount previously paid by Landlord within ten (10) days of the date of such
statement. If such statement reflects that the amount deposited into Escrow Account by Tenant as the Tenant Improvement Overage was greater than the amount required to be paid by Tenant, then Tenant shall be entitled to a prompt refund of any such
amounts. 
 (d)    Unless otherwise specified in the Plans, materials used for the Tenant Improvements at the Building
shall be good quality, new, and customary for the type of upfit contemplated in this Lease and in facilities comparable to the Building and readily available in the market where the Building is located, all as reasonably determined by Landlord. 

(e)    During construction of the Tenant Improvements, Landlord shall provide weekly written progress reports to Tenant
necessary for Tenant to review work schedules, costs, expenses and construction issues regarding the construction of the Tenant Improvements. The parties will hold periodic meetings, at mutually agreed upon times and locations, to discuss the
progress of the construction of the Tenant Improvements. The General Contractor will provide an updated Budget, Schedule, and RFI log every two weeks during construction of the Tenant Improvements. The General Contractor and Landlord reserve the
right to cure self imposed delays in the Schedule. 

  
 39 

 (f)    Should a default or event of default occur by Tenant hereunder
prior to the Commencement Date, Landlord shall have the right to cease all construction of the Tenant Improvements, and pursue all of its rights and remedies hereunder, or available at law or in equity for any such default or event of default. 

2.    Space Planning, Design and Working Drawings. Tenant shall engage Integrated Design (the “Architect”) to
prepare the Plans. After execution of this Lease, Tenant may seek reimbursement from the Tenant Improvement Allowance for fees paid to the Architect. The Architect’s fees shall be paid from the Tenant Improvement Allowance by Landlord upon
receipt and approval by Landlord of invoices and lien waivers for work performed. Belk Architecture or another architect with historic tax credit expertise (the “Landlord’s Architect”) shall review the Plans to insure compliance with
the requirements of State and Federal law for historic tax credits and all the costs for such review shall be borne by Landlord. If the Landlord’s Architect identifies any changes that must be made to the Plans solely for the purposes of
complying with requirements for historic tax credits, the costs of designing and constructing such changes shall be borne by Landlord provided there has been no material deviation from the Plans attached as Exhibit
D-1. Tenant shall review and respond to any request for approval of the draft plans or final Plans (by U.S. Mail, facsimile, or email) within five (5) business days after a request from either the
Architect or Landlord. Any modifications of the Plans sought by Tenant shall be reviewed and subject to the approval of Landlord prior to the modification of the Plans. All communication by Tenant to Landlord with respect to the Tenant Improvements
shall be in writing. Tenant shall designate an Authorized Representative to work with Landlord with respect to the Tenant Improvements, and Landlord shall not be obligated to respond to any instructions, approvals, changes, or other communications
from anyone claiming to act on Tenant’s behalf other than Tenant’s Authorized Representative. Review and approval by Landlord of the Plans shall not be construed as any statement by Landlord as to the compliance of the Plans with
Applicable Laws. 
 3.    Construction of Tenant Improvements. Landlord shall obtain all state and local
licenses, permits and approvals (whether governmental or non-governmental) required to construct the Tenant Improvements and for Tenant’s occupancy of the Premises. Landlord shall provide access to the
General Contractor for Construction of the Tenant Improvements and to the extent such access requires entry through space occupied by other tenants, Landlord shall provide for such access at its sole cost and expense. The Landlord shall engage,
subject to Tenant’s reasonable approval, a general contractor to construct the Tenant Improvements (the “General Contractor”). The General Contractor shall construct and install the Tenant Improvements in accordance with the
Plans which expense shall be deducted from the Tenant Improvement Allowance. The Tenant Improvements shall be delivered via Associated General Contractors (AGC) Guaranteed Maximum Price Contract (the “Contract”) with Liquidated Damages of
$500.00 per day for each day of delay in achieving in substantial completion beyond the date specified in the Contract, which date shall be no later than October 1, 2010, and a payment and performance bond. Any Liquidated Damages (less cost of
collection) paid to Landlord shall accrue to the Tenant; provided, however, any paid Liquidated Damages for any Tenant Delay shall accrue to Landlord. The General Contractor shall obtain at least three (3) bids for all major trade work at the
Premises. Landlord will work with the General Contractor to complete the Tenant Improvements by the Commencement Date. All contracts with vendors and subcontractors for construction of the Tenant Improvements will be negotiated by the General
Contractor. All work performed in 

  
 40 

 
connection with the construction of the Premises shall be performed in a good and workmanlike manner, in accordance with all Applicable Laws and the final approved Plans. If materials are not
readily available, require quick ship charges, or require substitution, the Tenant will be given notice and the opportunity to select alternate materials. Landlord shall insure that the Architect conducts a periodic review (a minimum of once every
two weeks) of the progress of construction to ensure compliance with the Plans. Tenant may from time to time request in writing changes to the Plans (a “Change Order”), subject to Landlord’s consent, which shall not be unreasonably
withheld. Landlord shall cause Contractor to provide an estimate of any change in the Construction Cost and/or Schedule. Tenant shall have the right to elect whether or not to proceed with the Change Order within five (5) business days after
receipt of such estimate. Upon such approval by Tenant, or confirmation by Landlord that the Change Order will not result in any change in cost and/or Schedule, Landlord shall implement the Change Order as part of the Tenant Improvements. 

Tenant acknowledges that the following items may result in changes to the Budget and/or Schedule: 

(i)    Municipal or other governmental inspectors require changes to the Premises such as code compliance changes. In such
event, Landlord will notify Tenant of the required changes, but the increased cost of such changes, if any, and any delay associated with such changes shall be the responsibility of Tenant. 

(ii)     Change Orders approved by Tenant. Any increased costs and delays due to such approved Change Orders shall be the
responsibility of Tenant. Any delays caused by such approved Change Orders shall not delay the Commencement Date of the Lease. Landlord shall not charge Tenant any administrative fees in respect of any Change Orders. Tenant shall have five
(5) business days to review and approve all Change Orders and any additional review time by Tenant shall be a Tenant Delay. 

(iii)    If materials are not readily available, require quick ship charges, or require substitution, provided Landlord
shall identify any such materials within ten (10) days of final approval of the Plans, and in any such case, Tenant will be given notice and the opportunity to select alternate materials. 

(iv)    Any Tenant Delay. 

4.    Repairs and Corrections. Landlord shall require of the General Contractor and any subcontractor constructing the
Tenant Improvements no less than a one year express repair and/or replacement warranty covering such work. All manufacturers’ and builders’ warranties with respect to the Tenant Improvements shall be assigned to Tenant to the extent
possible and necessary to assist Tenant in effecting any of Tenant’s repair obligations under the Lease without recourse to Landlord. Landlord agrees to enforce for the benefit of Tenant any warranties or guarantees issued in connection with
construction of the Tenant Improvements. Tenant shall repair or correct any defective work or materials installed by Tenant or any contractor other than the General Contractor (except subcontractors engaged by the General Contractor), or any work or
materials that prove defective as a result of any act or omission of Tenant or any Tenant Party, provided that selection of materials by Tenant is not such an act or omission, and provided further that work and materials done or installed by the
General Contractor or its vendors and subcontractors is not such an act or omission. For purposes of this Section, Landlord will not be considered to be Tenant’s agent, invitee, licensee, subtenant, customer, client, or guest.

Landlord believes that substantial completion of the Tenant Improvements has been achieved. Promptly following delivery of such notice, Tenant’s Representative and Landlord’s Representative shall jointly inspect the Tenant Improvements,
and, Landlord and Tenant shall mutually and reasonably prepare a punchlist of items remaining with respect to the Tenant Improvements that require repair or completion (the “Punchlist”). Pursuant to its Contract with Landlord, General
Contractor shall make all repairs and completions noted on the Punchlist with respect to the Tenant Improvements within forty-five (45) days (extended for Force Majeure and any Tenant Delay) after receipt of the Punchlist, with any Liquidated
Damages paid by the General Contractor for a delay in completion of the Punchlist accruing to the benefit of Tenant. Landlord acknowledges and represents that the Contract will include liquidated damages for delays in final completion (including

 FIRST AMENDMENT TO THE LEASE AGREEMENT 

THIS FIRST AMENDMENT TO LEASE AGREEMENT (the “Amendment”) is made and entered into as of the 19th day of August, 2011 by and between VENABLE TENANT, LLC, a North Carolina limited liability company (the “Landlord”), and PRECISION BIOSCIENCES, INC., a Delaware Corporation (the
“Tenant”). 
 WITNESSETH: 

WHEREAS, pursuant to that certain Lease Agreement dated April 5, 2010 by and between Landlord and Tenant (the “Lease”),
Tenant leased certain premises located in the Dibrell A Warehouse Building at 302 East Pettigrew Street, Durham, North Carolina (the “Building”) and consisting of approximately 8,274 rentable square feet, as more particularly described in
the Lease (the “Premises”); and 
 WHEREAS, the parties desire to modify the Lease as provided herein. 

NOW, THEREFORE, in consideration of cash in hand paid and the promises and the provisions contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, Landlord and Tenant hereby agree to amend and modify the Lease as follows: 

1.    Roof Access. 

(a)    Tenant has requested and Landlord has agreed that Tenant, its agents, employees, and independent contractors (all of
the foregoing, together with Tenant shall be referred to herein collectively, as the “Tenant Parties” or each as a “Tenant Party”) may have access to the roof of the Building (the “Roof”) provided that Tenant complies
with the following terms and conditions: 
 (i)    Tenant shall maintain insurance against loss or damage to person
(including death) or property due to any act or omission of any Tenant Party in connection with the access of the Roof and conduct of work thereon; 

(ii)    The sole purpose for access by a Tenant Party to the Roof is the repair, maintenance and replacement of HVAC units,
and/or generators owned by Tenant and located on the Roof; 
 (iii)    To the extent caused by a Tenant Party’s
access to the Roof or conduct of work thereon, Tenant shall promptly repair any damage to the Roof, or any property of Landlord or of any other tenant of the Building located thereon caused by Tenant Party. Landlord reserves the right to make said
repairs, at the sole expense of the Tenant, if Tenant repairs do not occur in a timely fashion or in the event other Tenants of the building are negatively impacted as a result of the repair timing and Tenant shall remit payment to the Landlord of
its actual and reasonable costs incurred in effecting any such repairs within ten business days after demand made by Landlord and documentation of Landlord’s costs provided to Tenant therefore; 

 (iv)    Landlord shall have the right to limit access by Tenant to the
Roof in the event of an emergency or other circumstance that requires such limitation; 
 (v)    No act or omission by a
Tenant Party shall result in penetration of the membrane of the Roof; and 
 (vi)    Tenant shall comply with all
Applicable Laws (as defined in the Lease) in connection with its access to the Roof and conduct of work thereon. 

(b)    Notwithstanding any provision of this Amendment to the contrary, if any Tenant Party shall fail to comply with the
terms and conditions stated herein, Landlord may terminate the right of Tenant to access the Roof upon ten (10) days prior written notice to Tenant specifying the reason for such termination. 

(c)    Tenant acknowledges on behalf of each Tenant Party that there are no walls, railings, barriers, or other structures
on the edges of the Roof (defined as the “Roof Condition”), and understands the potential danger and risk associated with its entry thereon, and Tenant acknowledges that Tenant is not aware of any obligation Landlord has to modify the Roof
Condition existing as of this date. 
 (d)    Landlord shall not be liable and Tenant hereby remises, releases and
forever discharges Landlord, and its owners, directors, members, shareholders, members, managers, affiliates, partners, officers, insurers, agents (including, but not limited to, the property manager of Landlord, Scientific Properties, LLC),
accountants, employees, attorneys, and assigns of and from any and all claims resulting from a Tenant Party’s breach of the terms of this Amendment. Tenant shall indemnify, defend and hold Landlord harmless from and against any and all loss,
liability, damages (including, but not limited to personal injury, death, or property damage), costs, expenses, and attorneys’ fees incurred by Landlord arising from (i) any breach by a Tenant Party of this Amendment; or (ii) any
entry by a Tenant Party upon the Roof, unless any such loss, liability, damages (including, but not limited to, personal injury, death or property damage) is due to a breach by Landlord of this Amendment. 

2.    Acknowledgement. Landlord acknowledges and agrees that nothing in this Amendment shall limit Landlord’s
obligation to maintain and repair the Roof and the Building pursuant to Sections 7 and 10 of the Lease for any maintenance and/or repairs not resulting from damage by a Tenant Party. 

3.    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. 

4.    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. 

  
 51 

 5.    Authority of Parties. Each party hereto hereby certifies
that it is authorized to enter into this Amendment, and that those persons signing below on its behalf are authorized to do so. 

6.    Full Force and Effect. Except as modified hereby, the Lease is hereby reaffirmed, unmodified and in full
force and effect. 
 7.    Governing Law. This Amendment shall be governed by and construed in accordance with
the laws of the State of North Carolina. 
 8.    Mutual Acknowledgment of
Non-Existence of Claims. Except as provided herein, 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.

 SECOND AMENDMENT TO THE LEASE AGREEMENT 

THIS SECOND AMENDMENT TO THE LEASE AGREEMENT (the “Amendment”) is made and entered into as of July 13, 2015 by and
between VENABLE TENANT, LLC, a North Carolina limited liability company (the “Landlord”), and PRECISION BIOSCIENCES, INC., a Delaware corporation (the “Tenant”). 

WITNESSETH: 
 WHEREAS, pursuant
to that certain Lease Agreement dated April 5, 2010, as amended by that certain First Amendment to Lease Agreement dated August 19, 2011, by and between Landlord and Tenant, Tenant leased certain premises known as Suite 100 in the Dibrell
A Building at 302 East Pettigrew Street, Durham, NC (the Lease Agreement and all amendments thereto shall be referred to herein collectively as the “Lease”); and 

WHEREAS, Tenant has requested and Landlord has agreed to modify the Lease as provided herein. 

NOW, THEREFORE, in consideration of cash in hand paid and the promises and the provisions contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, Landlord and Tenant hereby agree as follows: 

1.    Definition of Terms. All capitalized terms contained herein and not otherwise defined shall be defined as
provided in the Lease. 
  

	2.	 Term. 

(a) The term of the Lease currently expires on February 28, 2016. Landlord has agreed to extend the term of the Lease for a period of
sixty-five (65) months (the “Extended Term”) for a revised Termination Date of July 31, 2021. 
 (b) During the
Extended Term, the Premises shall be leased by Tenant “as is” except as expressly provided herein, and subject to Landlord’s continuing Lease obligations (such as repair and maintenance). 

3.    Premises. 

(a) Tenant has requested and Landlord has agreed to an expansion of the Premises (collectively, the “Expansion Space”) to
include the addition of (i) approximately 8,427 rentable square feet on the second floor of the Building known as Suite 200, and (ii) approximately 2,863 rentable square feet known as Suite 30 in the building known as the Receiving Room. A
floor plan of the Expansion Space is attached hereto and made a part hereof as Exhibit A. 
 (b) The term of the Lease for the
Expansion Space shall commence upon the date that the Expansion Space is substantially complete (as evidenced by a certificate of occupancy issued by the City of Durham and certification of substantial completion by the Architect), which it is
estimated shall occur on September 1, 2015 (the “Expansion Commencement Date”), and shall terminate on the revised Termination Date. On the Expansion Commencement Date, the term

 
“Premises” under the Lease shall include the Expansion Premises, and the term “Building” shall be deemed to include the Receiving Room Building. Notwithstanding the foregoing,
upon Tenant’s request and within a reasonable timeframe thereafter, Landlord shall advise Tenant if a portion of the Expansion Space (the “Early Portion”) may be occupied by Tenant before the entirety of the Expansion Space is
completed and Tenant shall advise Landlord if it desires to occupy the Early Portion. Early occupancy of the Early Portion shall not trigger the Expansion Commencement Date or the Expansion Rent Abatement (as defined herein) and for such occupancy,
Tenant shall pay an equitable portion of the Base Rent based upon the then current rate for the Premises, and any other charges for the Early Portion (including increased charges for Operating Expenses based upon the increased Tenant’s
Proportionate Share), with Landlord and Tenant negotiating reasonably and in good faith to determine such charges based on the square footage of the Early Portion and the number of days Tenant occupies the Early Portion for the conduct of its
business prior to the actual Expansion Commencement Date at which time, Tenant shall pay the Base Rent set forth in the Landlord’s Notice (as defined herein). 

(c) Effective upon the Expansion Commencement Date, Tenant’s Proportionate Share of the Dibrell A Warehouse Building shall be
32.32431 percent, Tenant’s Proportionate Share of the Receiving Room / Prizery Building shall be 8.41119 percent, and Tenant’s Proportionate Share of the Project shall be 22.82741 percent. 

4.    Upfit of Expansion Space. Landlord shall provide an allowance to Tenant for its use in the upfit of the
Expansion Space in an amount of up to $250,000 (the “Upfit Allowance”). The Upfit Allowance may be used by Tenant for permitting, construction, architectural and engineering costs, including, costs for cable and information
technology. The manner in which Upfit Allowance is to be provided and details of construction of the upfit for the Expansion Space shall proceed per the terms of the Work Letter attached hereto and made a part hereof as Exhibit B. 

5.    Base Rent. 

(a) Commencing upon the Expansion Commencement Date, Base Rent shall be due and payable for the portion of the Premises located in the
(i) Dibrell Building of approximately 16,539 rentable square feet (Suites A-100 and A-200) at the rate of $18.50 per rentable square feet, triple-net, with a Base Annual Rent Escalation of 2.75 percent each Lease Year, and (ii) Receiving Room Building (Suite RR-30) of approximately 2,863 rentable square
feet at the rate of $21.25 per rentable square feet, full service, with a Base Annual Rent Escalation of 2.75 percent each Lease Year. 

(b) Provided there is no event of default under the Lease then in effect, commencing with the Expansion Commencement Date, Base Rent under the
Lease shall be abated for a period of five months (the “Expansion Rent Abatement”). 
 6.    Base
Year. The Base Year for the purposes of calculating Additional Rent attributable to increases in Operating Expenses for the Receiving Room, Suite 30 shall be 2016. 

7.    Operating Expenses. During the Extended Term, Tenant shall continue to pay Tenant’s Proportionate Share
of Operating Expenses as provided in the Lease, and amended hereby 

  
 2 

 
for the portion of the Expansion Space located in the Dibrell Building. During 2015 and the Base Year of 2016, Tenant will not pay for Operating Expenses attributable to Suite RR-30, as the Base Rent for the Receiving Room space is a full-service rate with a 2016 base stop. In subsequent Lease Years, , Tenant will be charged for increases in Operating Expenses attributable to Suite RR-30 over and above the Base Year 2016. 
 8.    Direct Tenant Expenses.
Tenant will arrange for the provision of service and shall pay directly to each service provider all charges as follows: 
 a. Suites A-100 and A-200: all electricity, gas, and other utilities; janitorial, telephone and internet/data used on or from the Premises together with any taxes, penalties,
surcharges, or the like pertaining thereto 
 b. Suite RR-30: all telephone and internet/data used on
or from the Premises together with any taxes, penalties, surcharges, or the like pertaining thereto 
 9.    Security
Deposit. Section 9 of the Lease is hereby deleted and the following new Section 9 inserted in lieu thereof: 
 Promptly upon
the full execution of this Amendment (with delivery of a copy thereof to Tenant), Tenant shall deposit the amount required to increase the Security Deposit under the Lease to $123,269.08, four months Base Rent for the Premises on the Expansion
Commencement Date. Provided there is no default or event of default by Tenant under the Lease, the Security Deposit shall be reduced to (i) three months Base Rent on the first anniversary of the Expansion Commencement Date, and (ii) one
month Base Rent on the second anniversary of the Expansion Commencement Date. Landlord will not be required to apply all or any portion of the Security Deposit with respect to any particular violation or default by Tenant but Landlord may apply all
or any portion (as reasonably required to effect a cure) of the Security Deposit to any violation, breach, or default by Tenant hereunder. Landlord will be entitled to hold the Security Deposit in an account maintained by Landlord for such funds
from all tenants of Landlord. Any interest paid on such an account will become a part of the Security Deposit, accrue to the benefit of the Tenant (less any customary bank fees or charges for maintaining such account), and be delivered to Tenant
upon termination of this Lease provided that the Security Deposit and interest thereon have not been applied by Landlord to an event of default hereunder. Tenant will reimburse Landlord for such portions of the Security Deposit as Landlord will from
time to time apply with respect to any violation, breach, or default by Tenant hereunder promptly upon written notice of such application by Landlord. Any portion of the Security Deposit which has not been appropriated by Landlord in accordance with
the provisions hereof will be returned to Tenant within thirty (30) days after the termination of this Lease. 
 If Landlord conveys
Landlord’s interest under this Lease, the Security Deposit, or any part thereof not previously applied, shall be released by Landlord to Landlord’s grantee (to the extent not applied to any default by Tenant hereunder), and if so released,
Tenant agrees to look solely to such grantee for the proper application and return thereof in accordance with the Lease provided that Tenant receives written notice of such conveyance. Tenant agrees that Tenant will not assign, and that neither
Landlord, nor its successors and assigns, will be bound by any such assignment, encumbrance or pledge, attempted assignment, attempted pledge, or attempted encumbrance of the Security Deposit. 

  
 3 

 Any mortgagee or ground lessor will not be responsible to Tenant for the return or
application of the Security Deposit, whether or not it succeeds to the position of Landlord hereunder, unless the security deposit will have been received in hand by such mortgagee or ground lessor. 

Any unperformed obligations of Landlord or Tenant under this Section will survive the termination of the Lease, for whatever reason, or any
extension or renewal hereof. 
 10.    Right of Refusal.    Landlord hereby grants to Tenant
a one-time right of first refusal to lease space in the Project (the “Refusal Space”) under the terms and conditions as provided below: 

(i) So long as there is no default (beyond any applicable grace and/or cure period) or event of default by Tenant under the Lease, Landlord
will notify Tenant when it has all or a portion of the Refusal Space offered for lease to a third party (the “Third Party”) and the terms and conditions upon which Landlord is willing to lease such space (“Landlord’s
Notice”) . 
 (ii) Tenant shall provide written notice to Landlord, as to Tenant’s decision to lease or not to lease the
Refusal Space within ten (10) business days after Landlord’s Notice is received. If Tenant does provide to Landlord notice to lease the Refusal Space, Landlord and Tenant will negotiate in good faith to agree upon an amendment to the Lease
to add the Refusal Space within ten (10) business days after Landlord’s receipt of Tenant’s notice of intent to lease on all the same terms provided to the Third-Party. If Tenant does not provide written notice to Landlord within ten
(10) business days after receipt of the Landlord’s Notice, Tenant will have been deemed to have waived its right to lease the Refusal Space and Landlord shall be free to enter into a lease with the Third Party (upon substantially the same
terms and conditions listed in Landlord’s Notice), and Tenant shall have no further rights with respect to that particular Refusal Space within the Project. 

Once Landlord has offered a specific portion of the Refusal Space to Tenant, and Tenant has not leased such specific portion under the terms
and conditions provided in this Section, Tenant shall have no further right to such specific portion; provided, however, the balance of the Refusal Space that has not been offered to Tenant under this section remains subject to Tenant’s Right
of First Refusal provided herein. 
 The rights provided to Tenant in this Section (i) are subject to the
pre-existing rights of other tenants of the Building as described on Exhibit C, attached hereto and made a part hereof, and (ii) shall not inure to the benefit of any subtenant of all or a
portion of the Premises. 
 11.    Option to Extend. Tenant shall have the option to extend the term of the Lease
for one period of five Lease Years (the “Renewal Term”) provided that Tenant shall give written notice to Landlord of its desire to exercise its right to the Renewal Term at least one hundred and eighty days prior to the end of the
then current term; failing which the rights of Tenant under this Section shall be null and void and of no further force and effect. During the Renewal Term, the terms of the Lease shall continue in full force and effect, including, that Base Rent
shall continue to increase by the Base Rent Escalation. During the Renewal Term, the Premises shall be leased by Tenant “as is,” subject to Landlord’s continuing Lease obligations (such as repair and maintenance). 

  
 4 

 12.    Parking. With its lease of the Expansion Space, Tenant
shall have the non-exclusive right to the use of up to forty-five (45) parking spaces at the Project. 

13.    Keys to Premises. Tenant shall be provided one key and/or fob for each of its employees (now or hereafter
employed) for use at the Premises. Landlord shall have the right to charge a reasonable fee for replacement of any lost key or fob. 

14.    Brokerage. Tenant and Landlord each warrants and represents to the other that it has had no dealings with
any real estate broker or agent in connection with this Lease other than DTZ, the “Tenant Broker,” and Landlord agrees to pay a fee to the Tenant Broker pursuant to separate written agreement. Tenant and Landlord each covenants to pay,
hold harmless, and indemnify the other from and against any and all costs, expenses, liabilities (including reasonable attorneys’ fees), causes of action, claims or suits in connection with any compensation, commission, fee, or charges claimed
by any other real estate broker or agent with respect to this Lease or the negotiation thereof, arising out of any act of said party. 

15.    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. 

16.    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. 

17.    Authority of Parties. Each party hereto hereby certifies that it is authorized to enter into this Amendment,
and that those persons signing below on its behalf are authorized to do so. 
 18.    Full Force and Effect.
Except as modified hereby, the Lease remains unmodified and in full force and effect. 
 19.    Governing Law.
This Amendment shall be governed by and construed in accordance with the laws of the State of North Carolina. 

20.    Mutual Acknowledgment of Non-Existence of Claims. Except as provided
herein, 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. 
 21.    Effective Date. The provisions of this Amendment shall be effective as of the day and year
first written above. 
 22.    Rights of Tenant. Tenant shall have no options to renew or extend the term of the
Lease, rights to expand the Premises or rights of refusal except as expressly provided in this Amendment.

 EXHIBIT B 

WORK LETTER 
 This Exhibit B sets
forth the rights and obligations of Landlord and Tenant with respect to the construction of the improvements to the Expansion Space Premises as described on the Plans (“Tenant Improvements”). This Exhibit contemplates that the following
work will be performed, as further described herein, all subject to the prior review and approval by Landlord: (i) preparation of a space plan by the Architect; (ii) final design and engineering and preparation of plans, specifications,
and working drawings by the Architect (collectively, the “Plans”); (iii) preparation by the general contractor of Landlord (the “General Contractor”) of an estimate of the cost of the Tenant Improvements; (iv) submission to,
and approval of Plans by, appropriate governmental authorities; and (v) construction and installation of the Tenant Improvements pursuant to the Plans on or prior to the Commencement Date, subject to Force Majeure and any Tenant Delay. 

1.    Allowance/Payment of Construction Costs. 

(a)    Landlord and Tenant shall mutually-approve and select a General Contractor to construct the Tenant Improvements in
accordance with a milestone schedule (the “Schedule”), a copy of which shall be reasonably approved by Landlord and Tenant prior to commencement of construction of the Tenant Improvements. Landlord acknowledges and agrees that
Clancy & Theys is deemed approved as a potential Contractor, should Tenant so choose. Landlord and Tenant shall prepare and mutually and reasonably approve a budget (the “Budget”) for the costs to construct the Tenant Improvements
(the “Construction Costs”). The Budget will not include any amounts for furniture, fixtures (other than lighting), equipment, or personal property of Tenant, which items will be paid for by Tenant separately at its expense. The Budget
shall include a Construction Contingency which shall be 5% of the Construction Costs. Any unspent Construction Contingency will accrue to the Tenant. Change Orders (as hereinafter defined) shall be funded from increases in the Contract (as
hereinafter defined). Landlord agrees to fund a portion of the Construction Costs through the provision of the Upfit Allowance of $250,000. The Upfit Allowance shall be used for items specifically outlined in the Budget and mutually agreed upon by
both Landlord and Tenant. The Upfit Allowance shall be used only for construction, design, and management costs related to fixed improvements to the Building that are part of the Tenant Improvements. The Upfit Allowance may not be used to offset any
Rent payments owed to Landlord by Tenant. Any costs incurred due to a Tenant Delay shall be charged against the Upfit Allowance; provided, however, Tenant shall be given two (2) days’ notice and opportunity to cure any Tenant Delay
(including payment by Tenant of any costs associated with such cure such as higher shipping charges) before any costs are charged against the Upfit Allowance. Landlord and Tenant acknowledge and agree that the Construction Costs will be in excess of
the Upfit Allowance, and all costs for the Tenant Improvements in excess of the Upfit Allowance shall be borne by Tenant. Therefore, Tenant has agreed to place into an escrow account maintained with Landlord (the “Escrow Account”) an
amount equal to the Construction Costs as specified in the Budget minus the Upfit Allowance (the “Tenant Improvement Overage”). Landlord shall establish the Escrow Account as a separate, interest bearing account in an FDIC insured
institution. set forth below, Landlord shall have the authority to make periodic deductions from the Escrow Account as payment for the Construction Costs and the Escrow Account shall be funded in full by Tenant

prior to Landlord’s issuance of a Notice to Proceed to the General Contractor. Failure by Tenant to deposit the Tenant Improvement Overage into the Escrow Account within five
(5) business days after a request from Landlord hereunder shall be a Tenant Delay and a default in payment hereunder. Tenant shall receive all interest that accrues under the Escrow Account. 

(b)    The Upfit Allowance and Tenant Improvement Overage shall be disbursed by Landlord upon satisfaction of the following
conditions precedent: (i) Landlord shall have received applications for payment certified by the Architect, accompanied by evidence of the portion of the Tenant Improvements that have been completed per the Plans, invoices and paid receipts for
all such work completed, and copies of executed lien waivers from those persons providing such work; and (ii) all information and documentation provided to Landlord must be in form and substance reasonably approved by Landlord. Upon
Tenant’s request, Landlord shall provide Tenant an opportunity to review such information and documentation. 

(c)    Provided the aforesaid conditions are met, Landlord shall pay the Construction Costs at monthly intervals based upon
design and construction billing cycles. Each monthly payment of the Construction Costs shall be paid as follows: fifty percent (50%) of such payment shall be paid from the Upfit Allowance and the remaining fifty percent (50%) of such payment shall
be paid from the Tenant Improvement Overage through the Escrow Account. Within thirty (30) days after the Commencement Date, Landlord shall prepare and submit to Tenant a final statement that illustrates the total cost to construct the Tenant
Improvements and the amount paid from and remaining with respect to each of the Tenant Improvement Overage as held in the Escrow Account, and the Upfit Allowance. If such statement indicates that Landlord has paid less than the total amount of the
Upfit Allowance, then Landlord shall pay Tenant an amount equal to the Upfit Allowance minus the total amount previously paid by Landlord within ten (10) days of the date of such statement. If such statement reflects that the amount deposited
into Escrow Account by Tenant as the Tenant Improvement Overage was greater than the amount required to be paid by Tenant, then Tenant shall be entitled to a prompt refund of any such amounts. 

(d)    Unless otherwise specified in the Plans, materials used for the Tenant Improvements at the Building shall be good
quality, new, and customary for the type of upfit contemplated in this Lease and in facilities comparable to the Building and readily available in the market where the Building is located, all as reasonably determined by Landlord. 

(e)    During construction of the Tenant Improvements, Landlord and Tenant or their agents shall, on a weekly basis review
work schedules, costs, expenses and construction issues regarding the construction of the Tenant Improvements. The parties will hold periodic meetings, at mutually agreed upon times and locations, to discuss the progress of the construction of the
Tenant Improvements. The General Contractor will provide an updated Budget, Schedule, and RFI log every two weeks during construction of the Tenant Improvements. The General Contractor and Landlord reserve the right to cure self imposed delays in
the Schedule. 
 (f)    Should a default or event of default occur by Tenant hereunder prior to the Commencement Date,
Landlord shall have the right to cease all construction of the Tenant Improvements, and pursue all of its rights and remedies hereunder, or available at law or in equity for any such default or event of default. 

  
 9 

 2.    Space Planning, Design and Working Drawings. Tenant shall
engage Integrated Design (the “Architect”) to prepare the Plans. Tenant may include fees previously paid to the Architect in the approved Budget. Any Architect’s fees reimbursed to Tenant from the Upfit Allowance shall be paid from
the Upfit Allowance by Landlord upon receipt and approval by Landlord of invoices and lien waivers for work performed. If the Architect used by Tenant is not qualified with respect to compliance of the Plans with historic tax credit laws, statutes
and regulations, Belk Architecture or another architect with historic tax credit expertise shall review the Plans to insure compliance with the requirements of State and Federal law for historic tax credits and all the costs for such review shall be
borne by Landlord. Tenant shall review and respond to any request for approval of the draft plans or final Plans (by U.S. Mail, facsimile, or email) within five (5) business days after a request from either the Architect or Landlord. Any
modifications of the Plans sought by Tenant shall be reviewed and subject to the approval of Landlord prior to the modification of the Plans. All communication by Tenant to Landlord with respect to the Tenant Improvements shall be in writing. Tenant
shall designate an Authorized Representative to work with Landlord with respect to the Tenant Improvements, and Landlord shall not be obligated to respond to any instructions, approvals, changes, or other communications from anyone claiming to act
on Tenant’s behalf other than Tenant’s Authorized Representative. Review and approval by Landlord of the Plans shall not be construed as any statement by Landlord as to the compliance of the Plans with Applicable Laws.

 3.    Construction of Tenant Improvements. Landlord shall, via the General Contractor, obtain all state and
local licenses, permits and approvals (whether governmental or non-governmental) required to construct the Tenant Improvements and for Tenant’s occupancy of the Expansion Space. Landlord shall provide
access to the General Contractor for Construction of the Tenant Improvements and to the extent such access requires entry through space occupied by other tenants, Landlord shall provide for such access at its sole cost and expense. The Landlord
shall engage, subject to Tenant’s reasonable approval, a general contractor to construct the Tenant Improvements (the “General Contractor”). The General Contractor shall construct and install the Tenant Improvements in accordance with
the Plans which expense shall be deducted from the Upfit Allowance. The Tenant Improvements shall be delivered via Associated General Contractors (AGC) Guaranteed Maximum Price Contract (the “Contract”) with Liquidated Damages of $500.00
per day, and a payment and performance bond. Any Liquidated Damages (less cost of collection) paid to Landlord shall accrue to the Tenant; provided, however, any paid Liquidated Damages for any Tenant Delay shall accrue to Landlord. The General
Contractor shall obtain at least three (3) bids for all major trade work at the Expansion Space. Landlord will work with the General Contractor to complete the Tenant Improvements by the Commencement Date. All contracts with vendors and
subcontractors for construction of the Tenant Improvements will be negotiated by the General Contractor. All work performed in connection with the construction of the Expansion Space shall be performed in a good and workmanlike manner, in accordance
with all Applicable Laws and the final approved Plans. If materials are not readily available, require quick ship charges, or require substitution, the Tenant will be given notice and the opportunity to select alternate materials. Landlord shall
insure that the Architect conducts a periodic review (a minimum of once every two weeks) of the progress of construction to ensure compliance with the Plans. Tenant may from time to time request in writing changes to the Plans (a “Change
Order”), subject to Landlord’s consent, which shall not be unreasonably withheld. Landlord shall cause 

  
 10 

 
Contractor to provide an estimate of any change in the Construction Cost and/or Schedule. Tenant shall have the right to elect whether or not to proceed with the Change Order within five
(5) business days after receipt of such estimate. Upon such approval by Tenant, or confirmation by Landlord that the Change Order will not result in any change in cost and/or Schedule, Landlord shall implement the Change Order as part of the
Tenant Improvements. Landlord acknowledges that Tenant may hire the General Contractor and/or any subcontractors to perform other work items (in accordance with the terms and conditions of the Lease) within the original Premises concurrently with
the Tenant Improvements, provided such work does not require changes to the Schedule. 
 Tenant acknowledges that the following items may result in changes
to the Budget and/or Schedule: 
 (i)    Municipal or other governmental inspectors require changes to the Expansion
Space such as code compliance changes. In such event, Landlord will notify Tenant of the required changes, but the increased cost of such changes, if any, and any delay associated with such changes shall be the responsibility of Tenant. 

(ii)     Change Orders approved by Tenant. Any increased costs and delays due to such approved Change Orders shall be the
responsibility of Tenant. Any delays caused by such approved Change Orders shall not delay the Commencement Date of the Lease. Landlord shall not charge Tenant any administrative fees in respect of any Change Orders. Tenant shall have five
(5) business days to review and approve all Change Orders and any additional review time by Tenant shall be a Tenant Delay. 

(iii)    If materials are not readily available, require quick ship charges, or require substitution, provided Landlord
shall identify any such materials within ten (10) days of final approval of the Plans, and in any such case, Tenant will be given notice and the opportunity to select alternate materials. 

(iv)    Any Tenant Delay. 

4.    Repairs and Corrections. Landlord shall require of the General Contractor and any subcontractor constructing
the Tenant Improvements no less than a one year express repair and/or replacement warranty covering such work. All manufacturers’ and builders’ warranties with respect to the Tenant Improvements shall be assigned to Tenant to the extent
possible and necessary to assist Tenant in effecting any of Tenant’s repair obligations under the Lease without recourse to Landlord. Landlord agrees to enforce for the benefit of Tenant any warranties or guarantees issued in connection with
construction of the Tenant Improvements. Tenant shall repair or correct any defective work or materials installed by Tenant or any contractor other than the General Contractor (except subcontractors engaged by the General Contractor), or any work or
materials that prove defective as a result of any act or omission of Tenant or any Tenant Party, provided that selection of materials by Tenant is not such an act or omission, and provided further that work and materials done or installed by the
General Contractor or its vendors and subcontractors is not such an act or omission. For purposes of this Section, Landlord will not be considered to be Tenant’s agent, invitee, licensee, subtenant, customer, client, or guest. 

  
 11 

 5.    Punchlist. Landlord shall provide Tenant with written
notice when Landlord believes that substantial completion of the Tenant Improvements has been achieved. Promptly following delivery of such notice, Tenant’s Representative and Landlord’s Representative shall jointly inspect the Tenant
Improvements, and, Landlord and Tenant shall mutually and reasonably prepare a punchlist of items remaining with respect to the Tenant Improvements that require repair or completion (the “Punchlist”). Pursuant to its contract with
Landlord, General Contractor shall make all repairs and completions noted on the Punchlist with respect to the Tenant Improvements within forty-five (45) days (extended for Force Majeure and any Tenant Delay) after receipt of the Punchlist with
any Liquidated Damages paid by the General Contractor for a delay in completion of the Punchlist accruing to the benefit of Tenant.

 FOURTH AMENDMENT TO LEASE AGREEMENT 

THIS FOURTH AMENDMENT TO LEASE AGREEMENT (this “Amendment”) is made as of the
30th day of September, 2016 by and between VENABLE CENTER, LLC, a North Carolina limited liability company (“Landlord”), and PRECISION BIOSCIENCES, INC., a Delaware
corporation (“Tenant”), with respect to the following recitals: 
 (a)    Landlord is the current owner of a
group of interconnected buildings situated at 302 East Pettigrew Street, Durham, North Carolina known collectively as “Venable Center” (the “Project”), which comprises Dibrell A (“Dibrell A”), Dibrell B (“Dibrell
B”), the Receiving Room (the “Receiving Room”) and the Prizery (the “Prizery”). The first and second floors of the Prizery are shown in more detail on Exhibit B attached hereto and incorporated herein by
reference. 
 (b)    Pursuant to that certain Lease Agreement dated April 5, 2010, as modified by a First Amendment
to Lease Agreement dated August 19, 2011 and by a Second Amendment to the Lease Agreement dated July 13, 2015 (the “Second Amendment”) and by a Third Amendment to the Lease Agreement dated January 12, 2016 (collectively, the
“Lease”), Landlord (as successor to Venable Tenant LLC) leases to Tenant certain office space in the Project (the “Current Premises”) consisting of approximately 16,701 square feet of rentable area in Dibrell A (Suite A-100 = 8,274 RSF; Suite A-200 = 8,427 RSF, collectively referred to herein as the “Current DA Premises”) and 2,863 square feet of rentable area in the Receiving
Room (referred to herein as the “Current RR Premises”), as more particularly described in the Lease; 

(c)    The term of the Lease is currently scheduled to expire July 31, 2021. 

(d)    Landlord and Tenant have agreed to extend the term of the Lease, to add certain space to the premises demised under
the Lease, and to make certain other modifications to the Lease as set forth hereinbelow; 
 (e)    All capitalized terms
used in this Amendment that are not otherwise defined herein shall have the meanings ascribed to such terms in the Lease. 
 NOW, THEREFORE,
in consideration of the mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows: 

1.    The Term of the Lease is hereby extended through July 31, 2024 (the “Expiration Date”). 

 2.    Effective as of the respective Expansion Dates set forth below,
Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, the following additional premises in the Project, as outlined on Exhibit A attached hereto: 

(a)    approximately 11,621 Rentable Square Feet (“RSF”) located in the Receiving Room (the
“RR Expansion Premises”). The Expansion Date for the RR Expansion Premises shall be the 150th day following the date that Landlord delivers possession of the RR Expansion Premises to
Tenant (in good and tenantable condition, broom clean, with all systems serving same in good working order), which delivery date is anticipated to be September 15, 2016 (resulting in an anticipated Expansion Date of February 15, 2017);

 (b)    approximately 7,494 RSF located on the 2nd
floor of the Prizery (the “PR Second Floor Expansion Premises”), as shown on Exhibit B. Tenant acknowledges that certain portions of the PR Second Floor Expansion Premises are currently vacant and other portions of the PR
Second Floor Expansion Premises are currently occupied by various tenants. Landlord shall deliver possession of each portion of the PR Second Floor Expansion Premises to Tenant as such portion of the PR Second Floor Expansion Premises is vacant and
available to be delivered to Tenant (but, so long as Tenant does not commence the conduct of business in any portion of the PR Second Floor Expansion Premises, such partial delivery shall not trigger commencement of the term with respect to the
same, nor commencement of the Base Rent “clock,” as Tenant will be unable to commence its construction activities until the full floor is delivered in accordance with this Amendment; however, if Tenant commences the conduct of business in
any portion of the PR Second Floor Expansion Premises, then the term will commence with respect to all portions of the PR Second Floor Expansion Premises that have been delivered to Tenant). Landlord agrees to endeavor in good faith to terminate or
relocate the existing tenants of the PR Second Floor Expansion Premises, so as to deliver possession of each portion of the PR Second Floor Expansion Premises to Tenant as promptly as practicable. The Expansion Date with respect to the entire PR
Second Floor Expansion Premises (unless occurring sooner with respect to portions of the PR Second Floor Expansion Premises pursuant to the foregoing provisions of this Section 2(b)) shall be the thirtieth (30th) day following the date that possession of the entire PR Second Floor Expansion Premises is delivered to Tenant (in good and tenantable condition, broom clean, with all systems serving same in good
working order); 
 (c)    approximately 7,416 RSF on the first floor of Dibrell B (the “DB First
Floor Expansion Premises”). Tenant acknowledges that the DB First Floor Expansion Premises is currently occupied by a tenant whose lease term expires June 30, 2019, but that such current tenant may be induced to vacate the DB First Floor
Expansion Premises sooner than such scheduled lease expiration date. Tenant will take possession of the DB First Floor Expansion Premises as soon as such space is vacant and available. The Expansion Date for the DB First Floor Expansion Premises
shall be the 90th day following the date that Landlord delivers possession of the DB First Floor Expansion Premises to Tenant (in good and tenantable condition, broom clean, with all systems
serving same in good working order). Rent shall be paid on the same terms (on a per square foot basis) as the RR Expansion Premises; 

(d)    approximately 7,416 RSF on the second floor of Dibrell B (the “DB Second Floor Expansion
Premises”). Tenant acknowledges that the DB Second Floor Expansion Premises is currently occupied by a tenant whose lease term expires June 30, 2019. 

  
 2 

 
Landlord will use best efforts to cause the current tenant of the DB Second Floor Expansion Premises to vacate such space as soon as possible; provided that Landlord shall not be obligated to
offer such current tenant any payment or other economic inducement to vacate such space prior to the expiration of such current tenant’s lease term. Tenant will take possession of the DB Second Floor Expansion Premises as soon as such space is
vacant and available. The Expansion Date for the DB Second Floor Expansion Premises shall be the 30th day following the date that Landlord delivers possession of the DB Second Floor Expansion
Premises to Tenant (in good and tenantable condition, broom clean, with all systems serving same in good working order). Rent shall be paid on the same terms (on a per square foot basis) as the PR Second Floor Expansion Premises; 

3.    Base Rent with respect to each Expansion Premises shall be as set forth in the following tables:

 *Base Rent with respect to the DB First Floor Expansion Premises and the DB Second Floor Expansion Premises
shall commence to accrue only as of the respective Expansion Dates applicable to each of such spaces. From and after the respective Expansion Date applicable to each of such spaces, Base Rent shall be payable in the amounts set forth in the
foregoing tables (and any rental amounts shown in the foregoing tables as being in effect during the periods preceding such Expansion Dates shall be relevant only for the purpose of determining the applicable escalated rental amounts due from and
after such Expansion Dates). The purpose of measuring the periods in the foregoing tables from the Expansion Dates applicable to the RR Expansion Premises and the PR Second Floor Expansion Premises is so that the Base Rent per rentable square foot
in effect from time-to-time with respect to the DB First Floor Expansion Premises will be the same as the Base Rent per rentable square foot

in effect with respect to the RR Expansion Premises, and the Base Rent per rentable square foot in effect from
time-to-time with respect to the DB Second Floor Expansion Premises will be the same as the Base Rent per rentable square foot in effect with respect to the PR Second
Floor Expansion Premises. 
 Notwithstanding anything in the foregoing to the contrary, provided no Event of Default then exists under the Lease, Landlord
agrees to grant Tenant an abatement of the Base Rent due with respect to each of the Expansion Premises, in an amount as set forth herein. With respect to the RR Expansion Premises and the PR Second Floor Expansion Premises, the rental abatement
shall be five (5) monthly installments of the Base Rent. With respect to each Expansion Premises having an Expansion Date later than February 1, 2017 (other than the RR Expansion Premises and the PR Second Floor Expansion Premises), the
rental abatement shall be the product of (i) five (5) monthly installments of the Base Rent multiplied by (ii) a fraction, the numerator of which is the number of full calendar months remaining in the Term of this Lease as of the Expansion
Date applicable to such Expansion Premises and the denominator of which is eighty-nine (89). Such abatement shall be applied to the monthly installments of Base Rent that would otherwise be due for the months commencing with January 2018; provided
that, with respect to any Expansion Premises whose Expansion Date occurs later than January 1, 2018, the abatement period shall be the first full and partial calendar months following the Expansion Date applicable to such Expansion Premises.

 4.    Effective as of the Expansion Date for the RR Expansion Premises (which date is referred to herein as the
“RR Adjustment Date”), the Base Rent with respect to the Current RR Premises shall be converted to a “triple-net” rental rate, and Tenant shall pay, with respect to the Current RR Premises,
its Proportionate Share of all Operating Expenses from and after the Expansion Date for the RR Expansion Premises. Effective as of the RR Adjustment Date, the Base Rent with respect to the Current RR Premises shall be as set forth in the following
table:

 6.    Tenant’s Proportionate Share of Operating Expenses with respect to the
respective Expansion Premises is as follows: 
  

					
	Expansion Premises	  	Tenant’s Proportionate
Share of the Building	 	Tenant’s Proportionate
Share of the Project

	 DB Second Floor Expansion Premises
	  	50.00000%	 	8.62655%

 The Base Rent stated above with respect to the RR Expansion Premises and the DB First Floor Expansion Premises is a “triple-net” rental rate, and Tenant shall pay, with respect to each such Expansion Premises, its Proportionate Share of all Operating Expenses from and after the Expansion Date applicable to each such
Expansion Premises. The Base Rent stated above with respect to the PR Second Floor Expansion Premises and the DB Second Floor Expansion Premises is a “full-service” rental rate, and Tenant shall pay, with respect to each such Expansion
Premises, from and after January 1, 2018, its Proportionate Share of increases in Operating Expenses over the Operating Expenses incurred in calendar year 2017.

 7.    Landlord hereby agrees to grant Tenant an allowance
(“Improvements Allowance”) with respect to each Expansion Premises. The Improvements Allowance granted with respect to each Expansion Premises shall be calculated by reference to the Base Improvements Allowance per Rentable Square Foot
(“Base Amount”) set forth in the following table: 
  

			
	Expansion Premises	  	Base Improvements Allowance
per Rentable Square Foot
		
	 RR Expansion Premises
	  	$45.00
		
	 PR Second Floor Expansion Premises
	  	$25.00
		
	 DB First Floor Expansion Premises
	  	$45.00
		
	 DB Second Floor Expansion Premises
	  	$25.00

 For the RR Expansion Premises and the PR Second Floor Expansion Premises, the Improvements Allowance shall be the Base Amount
set forth in the foregoing table. For each Expansion Premises having an Expansion Date later than February 1, 2017 (other than the RR Expansion Premises and the PR Second Floor Expansion Premises), the Improvements Allowance shall be the
product of (i) the Base Amount set forth in the foregoing table multiplied by (ii) a fraction, the numerator of which is the number of full calendar months remaining in the Term of this Lease as of the Expansion Date applicable to such
Expansion Premises and the denominator of which is eighty-nine (89). 
 The Improvements Allowances shall be applied toward the cost of the design and
construction of any alterations Tenant desires to perform in the Expansion Premises in conjunction with Tenant’s initial occupancy of such Expansion Premises. Any portion of the Improvements Allowances may be applied to pay the fees of the
architect and engineers and any project manager employed by Tenant with respect to such alterations, as well as any permit costs and fees. 
 The cost of
Tenant’s alterations in each of the Expansion Premises shall be paid first out of the applicable Improvements Allowance until the Improvements Allowance is exhausted. Tenant shall deliver to Landlord, no more frequently than once per month,
invoices for work performed hereunder together with any other supporting documentation reasonably requested by Landlord. Provided no Event of Default then exists under the Lease, the Improvements Allowance (or portions thereof) shall be disbursed to
Tenant within thirty (30) days following Tenant’s submission to Landlord of paid invoices for work related to alterations performed by Tenant in the Expansion Premises, accompanied by waivers of liens executed by all contractors employed
by Tenant for the performance of such work. If the cost of Tenant’s alterations in the Expansion Premises exceeds the amount of the applicable Improvements Allowance, the excess shall be paid by Tenant after the Improvements Allowance is fully
exhausted. Notwithstanding the foregoing, the Improvements Allowance associated with any particular Expansion Premises may 

  
 7 

 
be utilized by Tenant in the Expansion Premises with which it is associated and/or in any other Expansion Premises that is delivered to Tenant either concurrently with or following the delivery
date of the Expansion Premises with which such Improvements Allowance is associated. Tenant may also submit invoices for an existing or completed Expansion Premises project when a new Improvements Allowance becomes available. 

Any portion of the Improvements Allowance that has not been utilized by the date that is twelve (12) months following the last Expansion Date applicable
to any of the Expansion Premises (as referenced in Section 2 of this Amendment) shall revert to Landlord. 
 In no event may any portion of the
Improvements Allowances may be utilized with respect to alterations or refurbishment performed in the Current Premises. 

8.    Landlord hereby agrees to grant Tenant an allowance in the amount of $97,820.00 (the “Refurbishment
Allowance”), to be applied toward the cost of performing alterations and refurbishment in the Current Premises. Any portion of the Refurbishment Allowances may be applied to pay the fees of the architect and engineers and any project manager
employed by Tenant with respect to such alterations, as well as any permit costs and fees. Provided no Event of Default then exists under the Lease, the Refurbishment Allowance (or portions thereof) shall be disbursed to Tenant within thirty
(30) days following Tenant’s submission to Landlord of paid invoices for alterations or refurbishment performed by Tenant in the Current Premises after the date of this Amendment, accompanied by waivers of liens executed by all contractors
employed by Tenant for the performance of such work (to the extent reasonably required). Requisitions shall be submitted by Tenant no more frequently than once per month. If the cost of Tenant’s alterations and refurbishment in the Current
Premises exceeds the amount of the Refurbishment Allowance, the excess shall be paid by Tenant after the Refurbishment Allowance is exhausted. Additionally, Tenant may elect to apply any unexpended Refurbishment Allowance toward work in any
Expansion Premises, on the same terms and conditions as listed in Section 7 above. 
 9.    Landlord acknowledges
that, following delivery of the RR Expansion Premises to Tenant, Tenant will be the exclusive user of the “private shipping and receiving area” of the loading dock in the Receiving Room, as shown on the attached Exhibit A
(the “S&R Area”), except as specifically provided herein. Landlord shall reasonably cooperate with Tenant to facilitate Tenant’s use of the loading dock as the primary user thereof; and Tenant agrees to afford Landlord and other
tenants of the Receiving Room reasonable access to and use of such loading dock, provided that such access and use does not materially impair Tenant’s use of such facility. Landlord agrees that it will use best efforts to give Tenant not less
than twenty-four (24) hours’ prior notice (which need not be in writing) to access and to use the loading dock so that Tenant can appropriately coordinate (clearance of space and security of items in the space). Tenant, at Tenant’s
sole cost, shall relocate the existing mailboxes in the loading dock to a mutually-agreeable location outside the S&R Area, and shall provide a means of access to the IT cabinet that does not require access through the S&R Area, such work to
be subject to Landlord’s reasonable prior approval. 

  
 8 

 10.    Tenant shall have the right, at Tenant’s expense and for its
own use, to purchase, install, maintain and operate at the Project an emergency power generator (the “Generator”) and a fuel tank (the “Tank”) for the Generator, subject to the following terms and conditions: 

(a)    The Generator and Tank and associated wiring shall be installed by contractors reasonably pre-approved by Landlord, in a good and workmanlike manner and in accordance with the reasonable directions of Landlord relative thereto. Tenant and/or its contractors shall provide all appropriate insurance for
such installation. Tenant shall deliver to Landlord detailed plans and specifications for the Generator and the Tank (including the proposed location of the Generator and the Tank) and a copy of Tenant’s contract for installing the Generator
and the Tank, which plans and specifications and contract and the location of the Generator and Tank shall be subject to Landlord’s reasonable approval. If deemed desirable by Landlord, Tenant shall cause the space within which the Generator
and Tank are located to be screened in a manner that is reasonably acceptable to Landlord. 
 (b) Tenant shall pay all costs of design,
installation, operation, utilization, replacement, maintenance and removal of the Generator and the Tank, including (without limitation) the cost of any piping needed to connect the Generator and the Tank. Any damage to the Project or other property
of Landlord or any other tenant resulting from the installation or maintenance of the Generator and Tank shall be promptly repaired at Tenant’s sole cost and expense. 

(c) Tenant covenants that it will not use its Generator or the Tank in a manner that will unreasonably interfere with Landlord’s and/or
any current or future tenant’s use of the Project. 
 (d) Tenant shall be responsible for procuring all licenses and permits required
for the installation, use or operation of the Generator and the Tank. 
 (e) The Generator and Tank shall be designed, constructed,
installed, maintained and operated in strict compliance with all applicable environmental laws. 
 (f) Landlord shall have no liability for
any damage to, or caused by, the Generator and Tank. Tenant hereby indemnifies and agrees to hold Landlord harmless from any loss or damage which Landlord may sustain in connection with the Generator and Tank, including all liabilities, costs or
expenses of any kind or nature incurred in connection with any claim or proceeding brought thereon and the defense thereof. 

(g)    Tenant is hereby granted nonexclusive easements and licenses for (i) use of any shafts required to install the
electrical wiring for the Generator; and (ii) access to the Generator and the Tank at all reasonable times and in emergencies. The Generator shall be connected to the Premises by electrical wiring, the installation of which shall be performed
by Tenant’s contractor, at Tenant’s sole expense. 
 (h)    At Landlord’s request, the Generator and Tank
and associated wiring and piping and any screening surrounding the Generator and Tank installed by Tenant hereunder shall be removed by Tenant, by contractors reasonably pre-approved by Landlord, in a good and
workmanlike manner, upon the expiration or earlier termination of the Lease, at Tenant’s sole cost and expense. 

  
 9 

 11.    The parking rights granted to Tenant under the Lease shall
increase proportionately upon the Expansion Date applicable to each Expansion Premises. 
 12.    This Amendment and all
provisions contained herein are contingent upon an executed lease termination agreement between Landlord and the existing tenant (“Roivant”) for the PR Second Floor Expansion Premises, providing that the PR Second Floor Expansion Premises
shall be surrendered to Landlord on or before January 1, 2017 (the “PR Termination Agreement”). If Landlord does not enter into said PR Termination Agreement within fifteen (15) days of the date of full execution of this
Amendment, then Tenant shall be entitled to terminate this Amendment (and all of its obligations hereunder) by written notice delivered to Landlord within thirty (30) days following the date of full execution of this Amendment (unless Landlord
has entered into the PR Termination Agreement prior to Tenant’s delivery of its termination notice, in which event this Amendment shall remain in force and effect). 

13.    The Right of Refusal granted to Tenant pursuant to Paragraph 10 of the Second Amendment shall remain in force and
effect during the Term of the Lease as extended by this Amendment. 
 14.    Except to the extent any of such suites are
sooner leased by Tenant pursuant to its Right of First Refusal, Landlord and Tenant hereby agree to the following “must-take” expansion provisions with respect to Suites 110, 120, 130, and 140 of the Prizery, as shown on Exhibit
B: 
 (a)    Landlord shall deliver Suite 130 and Suite 140, comprising approximately 3,162 rentable square feet
(“PR First Floor Expansion Premises A”) to Tenant on or around September 1, 2017 (the PR First Floor Expansion Premises A Target Date”). Landlord will use commercially reasonable efforts to meet the PR First Floor Expansion Premises A
Target Date. In the event Landlord is unable to deliver possession of the PR First Floor Expansion Premises A to Tenant on the PR First Floor Expansion Premises A Target Date due to an existing tenant’s failure to vacate such space or any other
cause beyond Landlord’s reasonable control, Landlord shall have no liability to Tenant, and Tenant’s obligation to lease the PR First Floor Expansion Premises A shall not be nullified, provided Landlord shall use commercially reasonable
efforts to deliver possession of the PR First Floor Expansion Premises A to Tenant as soon as possible following the PR First Floor Expansion Premises A Target Date. The Expansion Date for the PR First Floor Expansion Premises A shall be the 30th day following the date that Landlord delivers possession of PR First Floor Expansion Premises A to Tenant (in good and tenantable condition, broom clean, with all systems serving same in good
working order). Rent shall be paid on the same terms (on a per square foot basis) as the PR Second Floor Expansion Premises, and Tenant shall receive the same Improvement Allowance as the PR Second Floor Expansion Premises, on a per square foot
basis, and prorated in accordance with Section 7 of this Amendment. 
 (b)    Landlord shall deliver Suite 110 and
Suite 120, comprising approximately 2,722 rentable square feet (“PR First Floor Expansion Premises B”) to Tenant on or around November 1, 2018 (the “PR First Floor Expansion Premises B Target Date”). Landlord will use
commercially reasonable efforts to meet the PR First Floor Expansion Premises B Target Date. In the event Landlord is unable to deliver possession of the PR First Floor Expansion Premises B to Tenant on the PR First Floor Expansion Premises B Target
Date due to an existing tenant’s failure to vacate such space or any other cause beyond Landlord’s reasonable control, Landlord 

  
 10 

 
shall have no liability to Tenant, and Tenant’s obligation to lease the PR First Floor Expansion Premises B shall not be nullified, provided Landlord shall use commercially reasonable
efforts to deliver possession of the PR First Floor Expansion Premises B to Tenant as soon as possible following the PR First Floor Expansion Premises B Target Date. The Expansion Date for the PR First Floor Expansion Premises B shall be the 30th day following the date that Landlord delivers possession of PR First Floor Expansion Premises B to Tenant (in good and tenantable condition, broom clean, with all systems serving same in good
working order). Rent shall be paid on the same terms (on a per square foot basis) as the PR Second Floor Expansion Premises, and Tenant shall receive the same Improvement Allowance as the PR Second Floor Expansion Premises, on a per square foot
basis, and prorated in accordance with Section 7 of this Amendment. Following the addition of PR First Floor Expansion Premises B to the Premises, Landlord agrees that Tenant may add the previously shared “common space” to its secured
area, and Landlord and Tenant will mutually, in good faith, enter into a Lease amendment to document same. 

(c)    Notwithstanding anything in Paragraph 14(b) above, Tenant acknowledges that the current tenant of Suite 110 has the
option to renew the term of its lease for an additional period of three (3) years. In the event the current tenant of Suite 110 timely exercises its renewal option, Landlord shall so notify Tenant in writing (the “Suite 110 Notice”)
within fifteen (15) business days of Landlord’s receipt of same. In the event Landlord does not deliver the Suite 110 Notice to Tenant within fifteen (15) business days of the current tenant’s renewal deadline (which renewal
deadline Landlord represents, for the purposes of this Amendment, to be April 30, 2018), Landlord shall be conclusively deemed to have represented that the current Suite 110 tenant no longer has any valid right to renew, and Landlord shall
initiate work promptly and diligently to meet the PR First Floor Expansion Premises B Target Date. Within thirty (30) days following Tenant’s receipt of the Suite 110 Notice, Tenant may elect, by written notice to Landlord, to delete Suite
110 from the expansion space that is subject to the provisions of this Paragraph 14, in which event Landlord shall have no obligation to deliver possession of Suite 110 to Tenant at any time and Tenant shall have no obligation to lease Suite 110
from Landlord at any time. In the event Tenant does not timely exercise its right to delete Suite 110 from the expansion space under this Paragraph 14, then the delivery date for Suite 110 shall be extended to be the last day of the current
tenant’s three-year renewal term. Tenant’s right pursuant to Paragraph 14(b) above to convert common space into secured area shall be inapplicable unless and until Suite 110 (as well as the remainder of PR First Floor Expansion Premises B)
becomes part of the Premises demised to Tenant. 
 15.    The Option to Extend granted to Tenant pursuant to Paragraph
11 of the Second Amendment shall remain in force and effect and shall be applicable to the period immediately following the Term of the Lease as extended by this Amendment. 

16.    Landlord and Tenant each warrant to the other that in connection with this Amendment neither has employed or dealt
with any broker, agent or finder, other than CBRE-Raleigh, LLC and Cushman & Wakefield (the “Brokers”). Landlord acknowledges that it shall pay any commission or fee due to the Brokers, pursuant to a separate written agreement.
Each party shall indemnify and hold the other harmless from and against any claim for brokerage or other commissions asserted by any broker, agent or finder employed by the indemnifying party or with whom the indemnifying party has dealt, other than
the Brokers.

 IN WITNESS WHEREOF, Landlord and Tenant have executed and delivered this Amendment as of the
day and year first above written.

 FIFTH AMENDMENT TO LEASE AGREEMENT 

THIS FIFTH AMENDMENT TO LEASE AGREEMENT (this “Amendment”) is made as of the
24th day of January, 2018 by and between VENABLE CENTER, LLC, a North Carolina limited liability company (“Landlord”), and PRECISION BIOSCIENCES, INC., a Delaware
corporation (“Tenant”), with respect to the following recitals: 
  

	 	(a)	 Landlord is the current owner of a group of interconnected buildings situated at 302 East Pettigrew Street,
Durham, North Carolina known collectively as “Venable Center” (the “Project”), of which one of the buildings is known as the Prizery (the “Prizery”) and one of the buildings is known as Dibrell C (“Dibrell
C”). 

  

	 	(b)	 Pursuant to that certain Lease Agreement dated April 5, 2010, as modified by a First Amendment to Lease
Agreement dated August 19, 2011 and by a Second Amendment to the Lease Agreement dated July 13, 2015 (the “Second Amendment”) and by a Third Amendment to the Lease Agreement dated January 12, 2016, and by a Fourth Amendment
to the Lease Agreement dated September 30, 2016 (collectively, the “Lease”), Landlord (as successor to Venable Tenant LLC) leases to Tenant certain office space in the Project (the “Current Premises”), as more particularly
described in the Lease; 

  

	 	(c)	 Landlord and Tenant have agreed to add certain space to the premises demised under the Lease, and to make
certain other modifications to the Lease as set forth hereinbelow; 

  

	 	(d)	 All capitalized terms used in this Amendment that are not otherwise defined herein shall have the meanings
ascribed to such terms in the Lease. 

 NOW, THEREFORE, in consideration of the mutual covenants contained herein, and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows: 

1.    Effective as of a date to be selected by Landlord and falling between May 1, 2018 and May 15, 2018 (the
“Third Floor Expansion Date”), Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, Suite 300 (6,358 rsf), Suite 330 (546 rsf) and Suite 340 (202 rsf) in the Prizery (collectively, the “Third Floor Expansion
Premises”), as outlined on Exhibit A attached hereto. 

 2.    Base Rent with respect to the Third Floor Expansion Premises shall
commence to be payable on the date which is three (3) months following the Third Floor Expansion Date (the “TFEP Rent Date”), and shall thereafter be as follows: 

 

					
	Period	  	 Annual Base Rent per

Rentable Square Foot (FS)
	  	Monthly Rent
			
	TFEP Rent Date – 2/28/19	  	$25.69	  	$15,212.76*
	3/1/19 – 2/29/20	  	$26.39	  	$15,627.28
	3/1/20 – 2/28/21	  	$27.12	  	$16,059.56

	3/1/21 – 2/28/22	  	$27.87	  	$16,503.68
	3/1/22 – 2/28/23	  	$28.63	  	$16,953.73
	3/1/23 – 2/29/24	  	$29.42	  	$17,421.54
	3/1/24 – 7/31/24	  	$30.23	  	$17,901.20
			
		  		  	*prorated for any
 partial month

 Notwithstanding anything in the foregoing to the contrary, provided no Event of Default then exists under the Lease, Landlord
agrees to grant Tenant an abatement of the Base Rent due with respect to the Third Floor Expansion Premises, in an amount equal to $63,065.73. Such abatement shall be applied to the first monthly installments of Base Rent that would otherwise be due
for the Third Floor Expansion Premises. 
 3.    Tenant’s Proportionate Share of Operating Expenses with respect to
the Third Floor Expansion Premises is 20.92770% of the Prizery and 8.25647% of the Project. Tenant shall pay, with respect to the Third Floor Expansion Premises, from and after the thirtieth
(30th) day following the Third Floor Expansion Date, its Proportionate Share of increases in Operating Expenses over the Operating Expenses incurred in calendar year 2017. 

4.    Landlord hereby agrees to grant Tenant an allowance (“Third Floor Improvements Allowance”) with respect to
the Third Floor Expansion Premises in the amount of $151,701.12. The Third Floor Improvements Allowance shall be applied toward the cost of the design and construction of any alterations Tenant desires to perform in the Third Floor Expansion
Premises in conjunction with Tenant’s initial occupancy of such Third Floor Expansion Premises. Any portion of the Third Floor Improvements Allowance may be applied to pay the fees of the architect and engineers and any construction
supervision, contractors’ overhead and profit charges, along with fees for any project manager employed by Tenant with respect to such alterations, as well as any licensing and permitting costs and fees. 

The cost of Tenant’s alterations in the Third Floor Expansion Premises shall be paid first out of the Third Floor Improvements Allowance
until the Third Floor Improvements Allowance is exhausted. Tenant shall deliver to Landlord, no more frequently than once per month, invoices for work performed hereunder together with any other supporting documentation reasonably requested by
Landlord. Provided no Event of Default then exists under the Lease, the Third Floor Improvements Allowance (or portions thereof) shall be disbursed to Tenant within thirty (30) days following Tenant’s submission to Landlord of paid
invoices for work related to alterations performed by Tenant in the Third Floor Expansion Premises, accompanied by waivers of liens executed by all contractors employed by Tenant for the performance of such work. If the cost of Tenant’s
alterations in the Third Floor Expansion Premises exceeds the amount of the Third Floor Improvements Allowance, the excess shall be paid by Tenant after the Third Floor Improvements Allowance is fully exhausted. 

  
 2 

 Any portion of the Third Floor Improvements Allowance that has not been utilized by the date
that is twelve (12) months following the Third Floor Expansion Date shall revert to Landlord. 
 5.    The parking
rights granted to Tenant under the Lease shall increase proportionately upon the Third Floor Expansion Date. 

6.    Effective as of the “Dibrell Expansion Date” (as defined below), Landlord hereby leases to Tenant, and
Tenant hereby leases from Landlord, approximately 2,848 rentable square feet of space in the Dibrell C building (collectively, the “Dibrell Expansion Premises”), as outlined on Exhibit B attached hereto. In the event the final BOMA
calculation of the rentable area of the Dibrell Expansion Premises discloses that the rentable area of such space is less than 2,848 rentable square feet, the Monthly Rent set forth in Paragraph 7 below and Tenant’s Proportionate Share of
Operating Expenses with respect to the Dibrell Expansion Premises set forth in Paragraph 8 below shall be reduced pro rata. The “Dibrell Expansion Date” shall be the date following the date that the current tenant of a portion of the
Dibrell Expansion Premises, One Cow Standing, LLC, vacates the space occupied by such tenant, so that the space may be delivered by Landlord to Tenant. The Dibrell Expansion Date is anticipated to occur on April 1, 2020, but Landlord shall have
no liability to Tenant and this Amendment shall not be rendered void or voidable in the event Landlord is unable to deliver possession of the Dibrell Expansion Premises to Tenant by the anticipated Dibrell Expansion Date because the current tenant
fails to vacate by such date (despite Landlord’s commercially reasonable efforts to achieve same). In the event the current tenant vacates the Dibrell Expansion Premises prior to the anticipated Dibrell Expansion Date (such vacancy Landlord
shall use commercially reasonable efforts to notify Tenant of at least thirty (30) days in advance), the Dibrell Expansion Date shall be the 90th day following the date that Landlord delivers
possession of the Dibrell Expansion Premises to Tenant (in good and tenantable condition, broom clean, with all systems serving same in good working order). Landlord and Tenant agree to reasonably document (via
e-mail or otherwise in writing) the Dibrell Expansion Date, for the avoidance of confusion or misunderstanding. 

7.    Base Rent with respect to the Dibrell Expansion Premises shall commence to be payable on the date which is three
months following the Dibrell Expansion Date, and shall thereafter be as follows: 
  

					
	Period	  	 Annual Base Rent per

Rentable Square Foot (NNN)
	  	Monthly Rent
			
	4/1/20 – 3/31/21	  	$20.88	  	$4,955.52
	4/1/21 – 3/31/22	  	$21.46	  	$5,093.17
	4/1/22 – 3/31/23	  	$22.05	  	$5,233.20
	4/1/23 – 3/31/24	  	$22.65	  	$5,375.60
	4/1/24 – 7/31/24	  	$23.28	  	$5,525.12

 The foregoing rent schedule presumes that the Dibrell Expansion Date will be no earlier than April 1, 2020. In the event
the Dibrell Expansion Date occurs earlier than April 1, 2020, then (i) Annual 

  
 3 

 
Base Rent for any period falling between April 1, 2018 and March 31, 2019 for which rent is payable with respect to the Dibrell Expansion Premises shall be calculated based upon an
annual rate of $19.78 per rentable square foot, and (ii) Annual Base Rent for any period falling between April 1, 2019 and March 31, 2020 for which rent is payable with respect to the Dibrell Expansion Premises shall be calculated
based upon an annual rate of $20.32 per rentable square foot. 
 Notwithstanding anything in the foregoing to the contrary, provided no Event of Default
then exists under the Lease, Landlord agrees to grant Tenant an abatement of the Base Rent due with respect to the Dibrell Expansion Premises, in an amount equal to the product of (i) five (5) monthly installments of the Base Rent initially
applicable to the Dibrell Expansion Premises multiplied by (ii) a fraction, the numerator of which is the number of full calendar months remaining in the Term of the Lease as of the Dibrell Expansion Date and the denominator of which is
eighty-nine (89). Such abatement shall be applied to the first monthly installments of Base Rent that would otherwise be due for the Dibrell Expansion Premises. 

8.    Tenant’s Proportionate Share of Operating Expenses with respect to the Dibrell Expansion Premises is 14.19% of
Dibrell C and 3.30909% of the Project. Tenant shall pay, with respect to the Dibrell Expansion Premises, from and after the thirtieth (30th) day following the Dibrell Expansion Date, its
Proportionate Share of increases in Operating Expenses over the Operating Expenses incurred in calendar year 2017. 

9.    Landlord hereby agrees to grant Tenant an allowance (“Dibrell Improvements Allowance”) with respect to the
Dibrell Expansion Premises in an amount (per rentable square foot in the Dibrell Expansion Premises) equal to the product of (i) $45.00 multiplied by (ii) a fraction, the numerator of which is the number of full calendar months remaining in the
Term of this Lease as of the Dibrell Expansion Date and the denominator of which is eighty-nine (89). The Improvements Allowance shall be applied toward the cost of the design and construction of any alterations Tenant desires to perform in the
Dibrell Expansion Premises in conjunction with Tenant’s initial occupancy of such Dibrell Expansion Premises. Any portion of the Dibrell Improvements Allowance may be applied to pay the fees of the architect and engineers and any construction
supervision, contractors’ overhead and profit charges, along with fees for any project manager employed by Tenant with respect to such alterations, as well as any licensing and permitting costs and fees. 

The cost of Tenant’s alterations in the Dibrell Expansion Premises shall be paid first out of the Dibrell Improvements Allowance until
the Dibrell Improvements Allowance is exhausted. Tenant shall deliver to Landlord, no more frequently than once per month, invoices for work performed hereunder together with any other supporting documentation reasonably requested by Landlord.
Provided no Event of Default then exists under the Lease, the Dibrell Improvements Allowance (or portions thereof) shall be disbursed to Tenant within thirty (30) days following Tenant’s submission to Landlord of paid invoices for work
related to alterations performed by Tenant in the Dibrell Expansion Premises, accompanied by waivers of liens executed by all contractors employed by Tenant for the performance of such work. If the cost of Tenant’s alterations in the Dibrell
Expansion Premises exceeds the amount of the Dibrell Improvements Allowance, the excess shall be paid by Tenant after the Dibrell Improvements Allowance is fully exhausted. 

  
 4 

 Any portion of the Dibrell Improvements Allowance that has not been utilized by the date
that is twelve (12) months following the Dibrell Expansion Date shall revert to Landlord. 
 10.    The parking

THIS SIXTH AMENDMENT TO LEASE AGREEMENT (this “Amendment”) is made as of the 06 day of August, 2018 by and between VC
OWNER, LLC, a North Carolina limited liability company (“Landlord”), and PRECISION BIOSCIENCES, INC., a Delaware corporation (“Tenant”), with respect to the following recitals: 

A.    Pursuant to that certain Lease Agreement dated April 5, 2010, as modified by a First Amendment to Lease
Agreement dated August 19, 2011, and by a Second Amendment to Lease Agreement dated July 13, 2015, and by a Third Amendment to Lease Agreement dated January 12, 2016, and by a Fourth Amendment to Lease Agreement dated
September 30, 2016, and by a Fifth Amendment to Lease Agreement dated January 24, 2018 (collectively, the “Lease”), Landlord (as successor to Venable Tenant LLC) leases to Tenant certain office space in the group of

B.    Landlord and Tenant have agreed to add certain space to the premises demised under the Lease, and to make certain
other modifications to the Lease as set forth hereinbelow; 
 C.    All capitalized terms used in this Amendment that
are not otherwise defined herein shall have the meanings ascribed to such terms in the Lease. 
 NOW, THEREFORE, in consideration of the
mutual covenants contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows: 

1.    Landlord hereby leases to Tenant, and Tenant hereby leases from Landlord, approximately 1,626 rentable square feet
of space known as Suite C-185 (the “Suite C-185 Premises”) in the Dibrell Building (the “Building”) in the Project, as outlined on Exhibit A attached
hereto. The Term of the Lease with respect to the Suite C-185 Premises shall commence as of September 1, 2018, and shall be coterminous with the Term applicable to the remainder of the Premises. From and
after September 1, 2018, the Suite C-185 Premises shall constitute a portion of the “Premises” for all purposes under the Lease. Landlord shall have no liability to Tenant in the event Landlord
is unable to deliver possession of the Suite C-185 Premises to Tenant on September 1, 2018 due to the holding over by the prior tenant thereof or due to any other matter beyond Landlord’s reasonable
control; however, in such event, rent with respect to the Suite C-185 Premises will not begin to accrue until the first business day after Landlord is able to deliver possession of the Suite C-185 Premises to Tenant, broom clean and free of any prior tenancy. 
 2.    From and
after September 1, 2018, Tenant shall pay monthly Base Rent with respect to the Suite C-185 Premises in the amount of $3,929.50 per month, which amount shall escalate by 3.0% per annum on
September 1, 2019 and each September 1st thereafter. Notwithstanding the foregoing, provided Tenant is not then in default under the Lease beyond any applicable notice and cure period,
Landlord agrees to abate the first four (4) monthly installments of Base Rent with respect to the Suite C-185 Premises (only). 
  

 3.    Commencing on January 1, 2019, Tenant shall pay Additional
Rent with respect to the Suite C-185 Premises pursuant to Section 6 of the Lease. With respect to the Suite C-185 Premises (only), Tenant’s Proportionate Share
shall be 3.14714% for the Building and 1.89723% for the Project, and Tenant shall pay its Proportionate Share of increases in Operating Expenses over the Operating Expenses incurred in calendar year 2018. 

4.    Tenant shall accept the Suite C-185 Premises in their “as is”
condition (subject to Landlord’s continuing repair and maintenance obligations, as outlined in Section 10 of the Lease (as may be amended)), and Landlord shall have no obligation to make any alterations or improvements thereto whatsoever.
Any alterations that Tenant desires to make in the Suite C-185 Premises shall be subject to all the terms and conditions set forth in Section 11 of the Lease. Landlord hereby agrees to grant Tenant an
allowance (the “Granted Allowance”) in the amount of $32,520.00, to be applied toward the cost (including architectural and engineering fees) of alterations performed by Tenant in the Suite C-185
Premises. The Granted Allowance will be disbursed to Tenant within thirty (30) days following Tenant’s submission to Landlord of paid invoices with respect to such alterations, together with lien releases from Tenant’s contractor(s)
and any other supporting documentation reasonably required by Landlord. Any portion of the Granted Allowance that has not been applied (or contracted to be applied) in the manner set forth above by March 1, 2019 shall revert to Landlord, and
Tenant shall have no further rights with respect thereto. 
 5.    Concurrently with its execution of this Amendment,
Tenant shall deliver to Landlord the sum of $3,929.50, which shall be added to Tenant’s existing Security Deposit, and which combined sum shall continue to be held by Landlord throughout the Term pursuant to the provisions of Section 9 of
the Lease. 
 6.    Landlord and Tenant each warrant to the other that in connection with this Amendment neither has
employed or dealt with any broker, agent or finder, other than CBRE-Raleigh, LLC and Cushman & Wakefield (the “Brokers”). Landlord acknowledges that it shall pay any commission or fee due to the Brokers, pursuant to a separate
written agreement. Each party shall indemnify and hold the other harmless from and against any claim for brokerage or other commissions asserted by any broker, agent or finder employed by the indemnifying party or with whom the indemnifying party
has dealt, other than the Brokers. 
 7.    This Amendment and all provisions contained herein are contingent upon an
executed lease termination agreement between Landlord and the existing tenant (“RS&H, Inc.”) for the Suite C-185 Premises, providing that the Suite C-185
Premises shall be surrendered to Landlord on or before August 31, 2018 (the “RS&H Termination Agreement”). If Landlord does not enter into said RS&H Termination Agreement within fifteen (15) days of the date of full
execution of this Amendment, then Tenant shall be entitled to terminate this Amendment (and all of its obligations hereunder) by written notice delivered to Landlord within thirty (30) days following the date of full execution of this Amendment
(unless Landlord has entered into the RS&H Termination Agreement prior to Tenant’s delivery of its termination notice, in which event this Amendment shall remain in force and effect).

 8.    As modified by this Amendment, the Lease continues in full force
and effect. 
 IN WITNESS WHEREOF, Landlord and Tenant have executed and delivered this Amendment as of the day and year first above

THIS AMENDED AND RESTATED SEVENTH AMENDMENT TO LEASE AGREEMENT (this “Amendment”) is made as of the
             day of February, 2019 (the “Effective Date”) by and between VC OWNER, LLC, a Delaware limited liability company (“Landlord”), and
PRECISION BIOSCIENCES, INC., a Delaware corporation (“Tenant”), with respect to the following recitals: 

A.    Pursuant to that certain Lease Agreement dated April 5, 2010, as modified by a First Amendment to Lease
Agreement dated August 19, 2011, and by a Second Amendment to Lease Agreement dated July 13, 2015, and by a Third Amendment to Lease Agreement dated January 12, 2016, and by a Fourth Amendment to Lease Agreement dated

and by a Seventh Amendment to Lease Agreement (the “Seventh Amendment”) dated November 14, 2018 (collectively, the “Lease”), Landlord (as successor to Venable Tenant LLC) leases to Tenant certain office space
in the group of interconnected buildings situated at 302 East Pettigrew Street, Durham, North Carolina known collectively as “Venable Center” (the “Project”), as more particularly described in the Lease; 

B.    Landlord and Tenant have agreed to add certain space to the premises demised under the Lease, to amend, restate,
supersede, and replace that certain Seventh Amendment, and to make certain other modifications to the Lease as set forth hereinbelow; and 

C.    All capitalized terms used in this Amendment that are not otherwise defined herein shall have the meanings ascribed
to such terms in the Lease. 
 NOW, THEREFORE, in consideration of the mutual covenants contained herein, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, Landlord and Tenant agree as follows: 

1.    Premises. Subject to Section 7 of this Amendment, Landlord hereby leases to
Tenant, and Tenant hereby leases from Landlord, (i) approximately 7,416 rentable square feet of space known as Suite WB100 (the “Suite WB100 Premises”) in Dibrell B, which is located within the Dibrell Building (the
“Building”) in the Project, as outlined on Exhibit A-1 attached hereto and incorporated herein and (ii) approximately 7,416 rentable square feet of space known as Suite WB200 (the
“Suite WB200 Premises”, together with the Suite WB100 Premises, collectively, the “Premises”) in the Building in the Project, as outlined on Exhibit A-2 attached hereto
and incorporated herein. The Term of the Lease with respect to the Suite WB100 Premises shall commence as of March 1, 2019 (the “Suite WB100 Premises Seventh Amendment Commencement Date”) and shall be coterminous with the Term
applicable to the remainder of the Premises. The Term of the Lease with respect to the Suite WB200 Premises shall commence as of May 1, 2019 (the “Suite WB200 Premises Seventh Amendment Commencement Date”, together with the
Suite WB100 Premises Seventh Amendment Commencement Date, collectively, the “Seventh Amendment Commencement Date”) and shall be coterminous with the Term applicable to the remainder of the Premises. From and after the Suite WB100
Premises Seventh Amendment Commencement Date and the Suite WB200 Premises Seventh Amendment Commencement Date, respectively, the Suite WB100 Premises and the Suite WB200 Premises, respectively, shall constitute a portion of the “Premises”
for all purposes under the Lease. Landlord shall have no liability to Tenant in the event Landlord is unable to deliver possession of the Suite WB100 Premises and the Suite WB200 Premises to Tenant on the Suite WB100 Premises Seventh Amendment
Commencement Date and the Suite WB200 Premises Seventh Amendment Commencement Date, respectively, due to the holding over by the prior tenants thereof or due to any other matter beyond Landlord’s reasonable control (and further provided that
Landlord shall use commercially reasonable efforts to enforce its rights under the existing lease agreements as modified by the Amended and Restated Lease 

 
Termination Agreement, as hereinafter defined); however, in such event, Base Rent with respect to the Suite WB100 Premises and the Suite WB200 Premises, respectively, will not begin to accrue
until the first business day after Landlord is able to deliver possession of the Suite WB100 Premises and the Suite WB200 Premises to Tenant, broom clean and free of any prior tenancy. 

As of the Effective Date, the Suite WB100 Premises and the Suite WB200 Premises are occupied collectively by Hutson Law Office, P.A.

For purposes of
clarity, as of the Seventh Amendment Commencement Date, the suites designated as of the Effective Date as Suite B-140 and Suite B-260 shall no longer have such
designations and such premises shall be reconfigured and thereafter be known as Suite WB100 Premises and Suite WB200 Premises. Additionally, for purposes of clarity, Suite WB100 Premises is referred to in the Fourth Amendment as DB First Floor
Expansion Premises and Suite WB200 Premises is referred to in the Fourth Amendment as DB Second Floor Expansion Premises.

4.    Tenant Improvements. Subject to this Section 4, Tenant shall accept the

the architect and engineers and any construction supervision, contractors’ overhead and profit charges, along with fees for any project manager employed by Tenant with respect to such alterations, as well as any licensing and permitting costs
and fees; provided, the Suite WB100 Granted Allowance may only be used for the Suite WB100 Premises and the Suite WB200 Granted Allowance may only be used for the Suite WB200 Premises. 

The cost of Tenant’s alterations in the Suite WB100 Premises shall be paid first out the Suite WB100 Granted Allowance until the Suite
WB100 Granted Allowance is exhausted (at which time Tenant shall be fully responsible for the cost of any further alterations), and the cost of Tenant’s alteration in the Suite WB200 Premises shall be paid first out the Suite WB200 Granted
Allowance until the Suite WB200 Allowance is exhausted (at which time Tenant shall be fully responsible for the cost of any further alterations). Provided no Event of Default then exists under the Lease, the Granted Allowance (or portions thereof)
shall be disbursed to Tenant within thirty (30) days following Tenant’s submission to Landlord of paid invoices for work related to alterations performed by Tenant in the Suite WB100 Premises and Suite WB200 Premises, accompanied by
waivers of liens executed by all contractors employed by Tenant for the performance of such work. If the cost of Tenant’s alterations in the Suite WB100 Premises or the Suite WB200 Premises exceeds the amount of the Suite WB100 Granted
Allowance or the Suite WB200 Granted Allowance, the excess shall be paid by Tenant after the Suite WB100 Granted Allowance or the Suite WB200 Granted Allowance is fully exhausted. Any portion of the (i) Suite WB100 Granted Allowance that has

 5.    Security Deposit. Concurrently with its execution of
this Amendment, Tenant shall deliver the sum of $28,434.18 to Landlord as an additional portion of the Security Deposit, and accordingly the Security Deposit shall be increased by $28,434.18, which shall be held by Landlord throughout the Term
pursuant to the provisions of Section 9 of the Lease. 
 6.    Brokers. Landlord
and Tenant each warrant to the other that in connection with this Amendment neither has employed or dealt with any broker, agent or finder, other than CBRE -Raleigh, LLC (the “Landlord’s Broker”) and Cushman &
Wakefield (the “Tenant’s Broker”, together with Landlord’s Broker, collectively, “Brokers”). Landlord acknowledges that it shall pay any commission or fee due to the Landlord’s Broker, pursuant to a
separate written agreement. Landlord’s Broker shall pay any commission or fee due to Tenant’s Broker, pursuant to a separate written agreement. Each party shall indemnify and hold the other harmless from and against any claim for brokerage

7.    Contingency. This Amendment and all provisions contained herein are contingent upon (i) an
executed amended and restated lease termination agreement between Landlord and Hutson Law for the premises that Hutson Law leases from Landlord (the “Amended and Restated Hutson Law Lease Termination Agreement”) and (ii) an
executed amended and restated lease termination agreement between Landlord and Chapter 13 for the premises that Chapter 13 leases from Landlord (the “Amended and Restated Chapter 13 Lease Termination Agreement”, together with the

 Exhibit 10.10 

 

PRECISION BIOSCIENCES, INC. 

2019 INCENTIVE AWARD PLAN 

ARTICLE I. 
 PURPOSE

 The Plan’s purpose is to enhance the Company’s ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing these individuals with equity ownership opportunities. Capitalized terms used in the Plan are defined in Article XI. 

ARTICLE II. 
 ELIGIBILITY

 Service Providers are eligible to be granted Awards under the Plan, subject to the limitations described herein. 

ARTICLE III. 

ADMINISTRATION AND DELEGATION 

3.1 Administration. The Plan is administered by the Administrator. The Administrator has authority to determine which Service Providers
receive Awards, grant Awards and set Award terms and conditions, subject to the conditions and limitations in the Plan. The Administrator also has the authority to take all actions and make all determinations under the Plan, to interpret the Plan
and Award Agreements and to adopt, amend and repeal Plan administrative rules, guidelines and practices as it deems advisable. The Administrator may correct defects and ambiguities, supply omissions and reconcile inconsistencies in the Plan or any
Award as it deems necessary or appropriate to administer the Plan and any Awards. The Administrator’s determinations under the Plan are in its sole discretion and will be final and binding on all persons having or claiming any interest in the
Plan or any Award. 
 3.2 Appointment of Committees. To the extent Applicable Laws permit, the Board may delegate any or all of its
powers under the Plan to one or more Committees or officers of the Company or any of its Subsidiaries. The Board may abolish any Committee or re-vest in itself any previously delegated authority at any time.

 ARTICLE IV. 
 STOCK
AVAILABLE FOR AWARDS 
 4.1 Number of Shares. Subject to adjustment under Article VIII and the terms of this
Article IV, Awards may be made under the Plan covering up to the Overall Share Limit. As of the Plan’s effective date under Section 10.3, the Company will cease granting awards under the Prior Plans; however, Prior Plan Awards will
remain subject to the terms of the applicable Prior Plan. Shares issued under the Plan may consist of authorized but unissued Shares, Shares purchased on the open market or treasury Shares. 

4.2 Share Recycling. If all or any part of an Award or Prior Plan Award expires, lapses or is terminated, exchanged for cash,
surrendered, repurchased, canceled without having been fully exercised or forfeited, in any case, in a manner that results in the Company acquiring Shares covered by the Award or Prior Plan Award at a price not greater than the price (as adjusted to
reflect any Equity Restructuring) paid by the Participant for such Shares or not issuing any Shares covered by the Award or Prior Plan 

 
Award, the unused Shares covered by the Award or Prior Plan Award will, as applicable, become or again be available for Award grants under the Plan. Further, Shares delivered (either by actual
delivery or attestation) to the Company by a Participant to satisfy the applicable exercise or purchase price of an Award or Prior Plan Award and/or to satisfy any applicable tax withholding obligation (including Shares retained by the Company from
the Award or Prior Plan Award being exercised or purchased and/or creating the tax obligation) will, as applicable, become or again be available for Award grants under the Plan. The payment of Dividend Equivalents in cash in conjunction with any
outstanding Awards or Prior Plan Awards shall not count against the Overall Share Limit. 
 4.3 Incentive Stock Option Limitations.
Notwithstanding anything to the contrary herein, no more than 5,000,000 Shares may be issued pursuant to the exercise of Incentive Stock Options. 

4.4 Substitute Awards. In connection with an entity’s merger or consolidation with the Company or the Company’s acquisition of
an entity’s property or stock, the Administrator may grant Awards in substitution for any options or other stock or stock-based awards granted before such merger or consolidation by such entity or its affiliate. Substitute Awards may be granted
on such terms as the Administrator deems appropriate, notwithstanding limitations on Awards in the Plan. Substitute Awards will not count against the Overall Share Limit (nor shall Shares subject to a Substitute Award be added to the Shares
available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute Incentive Stock Options will count against the maximum number of Shares that may be issued pursuant to the exercise of Incentive Stock
Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a pre-existing plan
approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent
appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or
combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not be added to the Shares available for Awards under the Plan as provided above);
provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and
shall only be made to individuals who were not Employees or Directors prior to such acquisition or combination. 
 4.5 Non-Employee Director Compensation. Notwithstanding any provision to the contrary in the Plan, the Administrator may establish compensation for non-employee Directors from
time to time, subject to the limitations in the Plan. The Administrator will from time to time determine the terms, conditions and amounts of all such non-employee Director compensation in its discretion and
pursuant to the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, provided that the sum of any cash compensation, or other compensation, and the value
(determined as of the grant date in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, or any successor thereto) of Awards granted to a non-employee Director as
compensation for services as a non-employee Director during any fiscal year of the Company may not exceed $750,000. The Administrator may make exceptions to this limit for individual non-employee Directors in extraordinary circumstances, as the Administrator may determine in its discretion, provided that the non-employee Director receiving such additional
compensation may not participate in the decision to award such compensation or in other contemporaneous compensation decisions involving non-employee Directors.

 ARTICLE V. 

STOCK OPTIONS AND STOCK APPRECIATION RIGHTS 

5.1 General. The Administrator may grant Options or Stock Appreciation Rights to Service Providers subject to the limitations in the
Plan, including any limitations in the Plan that apply to Incentive Stock Options. The Administrator will determine the number of Shares covered by each Option and Stock Appreciation Right, the exercise price of each Option and Stock Appreciation
Right and the conditions and limitations applicable to the exercise of each Option and Stock Appreciation Right. A Stock Appreciation Right will entitle the Participant (or other person entitled to exercise the Stock Appreciation Right) to receive
from the Company upon exercise of the exercisable portion of the Stock Appreciation Right an amount determined by multiplying the excess, if any, of the Fair Market Value of one Share on the date of exercise over the exercise price per Share of the
Stock Appreciation Right by the number of Shares with respect to which the Stock Appreciation Right is exercised, subject to any limitations of the Plan or that the Administrator may impose and payable in cash, Shares valued at Fair Market Value or
a combination of the two as the Administrator may determine or provide in the Award Agreement. 
 5.2 Exercise Price. The
Administrator will establish each Option’s and Stock Appreciation Right’s exercise price and specify the exercise price in the Award Agreement. The exercise price will not be less than 100% of the Fair Market Value on the grant date of the
Option or Stock Appreciation Right. 
 5.3 Duration. Each Option or Stock Appreciation Right will be exercisable at such times and as
specified in the Award Agreement, provided that the term of an Option or Stock Appreciation Right will not exceed ten years. Notwithstanding the foregoing, if the Participant, prior to the end of the term of an Option or Stock Appreciation Right,
violates the non-competition, non-solicitation, confidentiality or other similar restrictive covenant provisions of any employment contract, confidentiality and
nondisclosure agreement or other agreement between the Participant and the Company or any of its Subsidiaries, the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the
Participant shall terminate immediately upon such violation, unless the Company otherwise determines. In addition, if, prior to the end of the term of an Option or Stock Appreciation Right, the Participant is given notice by the Company or any of
its Subsidiaries of the Participant’s Termination of Service by the Company or any of its Subsidiaries for Cause, and the effective date of such Termination of Service is subsequent to the date of the delivery of such notice, the right of the
Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant shall be suspended from the time of the delivery of such notice until the earlier of (i) such time as it is
determined or otherwise agreed that the Participant’s service as a Service Provider will not be terminated for Cause as provided in such notice or (ii) the effective date of the Participant’s Termination of Service by the Company or
any of its Subsidiaries for Cause (in which case the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant will terminate immediately upon the effective date of
such termination of Service). 
 5.4 Exercise. Options and Stock Appreciation Rights may be exercised by delivering to the Company a
written notice of exercise, in a form the Administrator approves (which may be electronic), signed by the person authorized to exercise the Option or Stock Appreciation Right, together with, as applicable, payment in full (i) as specified in
Section 5.5 for the number of Shares for which the Award is exercised and (ii) as specified in Section 9.5 for any applicable taxes. Unless the Administrator otherwise determines, an Option or Stock Appreciation Right may not be
exercised for a fraction of a Share. 

  
 3 

 5.5 Payment Upon Exercise. Subject to Section 10.8, any Company insider trading
policy (including blackout periods) and Applicable Laws, the exercise price of an Option must be paid by: 
 (a) cash, wire transfer of
immediately available funds or by check payable to the order of the Company, provided that the Company may limit the use of one of the foregoing payment forms if one or more of the payment forms below is permitted; 

(b) if there is a public market for Shares at the time of exercise, unless the Company otherwise determines, (A) delivery (including
telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to pay the exercise price, or (B) the
Participant’s delivery to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to pay the exercise price; provided that such
amount is paid to the Company at such time as may be required by the Administrator; 
 (c) to the extent permitted by the Administrator,
delivery (either by actual delivery or attestation) of Shares owned by the Participant valued at their Fair Market Value; 
 (d) to the
extent permitted by the Administrator, surrendering Shares then issuable upon the Option’s exercise valued at their Fair Market Value on the exercise date; 

(e) to the extent permitted by the Administrator, delivery of a promissory note or any other property that the Administrator determines is good
and valuable consideration; or 
 (f) to the extent permitted by the Company, any combination of the above payment forms approved by the
Administrator. 
 ARTICLE VI. 

RESTRICTED STOCK; RESTRICTED STOCK UNITS 

6.1 General. The Administrator may grant Restricted Stock, or the right to purchase Restricted Stock, to any Service Provider, subject
to the Company’s right to repurchase all or part of such shares at their issue price or other stated or formula price from the Participant (or to require forfeiture of such shares) if conditions the Administrator specifies in the Award
Agreement are not satisfied before the end of the applicable restriction period or periods that the Administrator establishes for such Award. In addition, the Administrator may grant to Service Providers Restricted Stock Units, which may be subject
to vesting and forfeiture conditions during the applicable restriction period or periods, as set forth in an Award Agreement. The Administrator will determine and set forth in the Award Agreement the terms and conditions for each Restricted Stock
and Restricted Stock Unit Award, subject to the conditions and limitations contained in the Plan. 
 6.2 Restricted Stock. 

(a) Dividends. Participants holding shares of Restricted Stock will be entitled to all ordinary cash dividends paid with respect to such
Shares, unless the Administrator provides otherwise in the Award Agreement. In addition, unless the Administrator provides otherwise, if any dividends or distributions are paid in Shares, or consist of a dividend or distribution to holders of Common
Stock of property other than an ordinary cash dividend, the Shares or other property will be subject to the same restrictions on transferability and forfeitability as the shares of Restricted Stock with respect to which they were paid. 

(b) Stock Certificates. The Company may require that the Participant deposit in escrow with the Company (or its designee) any stock
certificates issued in respect of shares of Restricted Stock, together with a stock power endorsed in blank. 

  
 4 

 6.3 Restricted Stock Units. 

(a) Settlement. The Administrator may provide that settlement of Restricted Stock Units will occur upon or as soon as reasonably
practicable after the Restricted Stock Units vest or will instead be deferred, on a mandatory basis or at the Participant’s election, in a manner intended to comply with Section 409A. 

(b) Stockholder Rights. A Participant will have no rights of a stockholder with respect to Shares subject to any Restricted Stock Unit
unless and until the Shares are delivered in settlement of the Restricted Stock Unit. 
 (c) Dividend Equivalents. If the
Administrator provides, a grant of Restricted Stock Units may provide a Participant with the right to receive Dividend Equivalents. Dividend Equivalents may be paid currently or credited to an account for the Participant, settled in cash or Shares
and subject to the same restrictions on transferability and forfeitability as the Restricted Stock Units with respect to which the Dividend Equivalents are granted and subject to other terms and conditions as set forth in the Award Agreement. 

ARTICLE VII. 
 OTHER
STOCK OR CASH BASED AWARDS 
 Other Stock or Cash Based Awards may be granted to Participants, including Awards entitling Participants
to receive Shares to be delivered in the future and including annual or other periodic or long-term cash bonus awards (whether based on specified Performance Criteria or otherwise), in each case subject to any conditions and limitations in the Plan.
Such Other Stock or Cash Based Awards will also be available as a payment form in the settlement of other Awards, as standalone payments and as payment in lieu of compensation to which a Participant is otherwise entitled. Other Stock or Cash Based
Awards may be paid in Shares, cash or other property, as the Administrator determines. Subject to the provisions of the Plan, the Administrator will determine the terms and conditions of each Other Stock or Cash Based Award, including any purchase
price, performance goal (which may be based on the Performance Criteria), transfer restrictions, and vesting conditions, which will be set forth in the applicable Award Agreement. 

ARTICLE VIII. 

ADJUSTMENTS FOR CHANGES IN COMMON STOCK 

AND CERTAIN OTHER EVENTS 

8.1 Equity Restructuring(a) . In connection with any Equity Restructuring, notwithstanding anything to the contrary in this
Article VIII, the Administrator will equitably adjust each outstanding Award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of securities subject to each outstanding Award and/or the
Award’s exercise price or grant price (if applicable), granting new Awards to Participants, and making a cash payment to Participants. The adjustments provided under this Section 8.1 will be nondiscretionary and final and binding on the
affected Participant and the Company; provided that the Administrator will determine whether an adjustment is equitable. 
 8.2 Corporate
Transactions. In the event of any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation, repurchase, recapitalization,
liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Common Stock or other securities of the Company, Change in Control, issuance of warrants or
other 

  
 5 

 
rights to purchase Common Stock or other securities of the Company, other similar corporate transaction or event, other unusual or nonrecurring transaction or event affecting the Company or its
financial statements or any change in any Applicable Laws or accounting principles, the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such
transaction or event (except that action to give effect to a change in Applicable Law or accounting principles may be made within a reasonable period of time after such change) and either automatically or upon the Participant’s request, is
hereby authorized to take any one or more of the following actions whenever the Administrator determines that such action is appropriate in order to (x) prevent dilution or enlargement of the benefits or potential benefits intended by the
Company to be made available under the Plan or with respect to any Award granted or issued under the Plan, (y) to facilitate such transaction or event or (z) give effect to such changes in Applicable Laws or accounting principles: 

(a) To provide for the cancellation of any such Award in exchange for either an amount of cash or other property with a value equal to the
amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights under the vested portion of such Award, as applicable; provided that, if the amount that could
have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights, in any case, is equal to or less than zero, then the Award may be terminated without payment; 

(b) To provide that such Award shall vest and, to the extent applicable, be exercisable as to all shares covered thereby, notwithstanding
anything to the contrary in the Plan or the provisions of such Award; 
 (c) To provide that such Award be assumed by the successor or
survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of
shares and/or applicable exercise or purchase price, in all cases, as determined by the Administrator; 
 (d) To make adjustments in the
number and type of shares of Common Stock (or other securities or property) subject to outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of the limitations in
Article IV hereof on the maximum number and kind of shares which may be issued) and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards; 

(e) To replace such Award with other rights or property selected by the Administrator; and/or 

(f) To provide that the Award will terminate and cannot vest, be exercised or become payable after the applicable event. 

8.3 Administrative Stand Still. In the event of any pending stock dividend, stock split, combination or exchange of shares, merger,
consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other extraordinary transaction or change affecting the Shares or the share price of Common Stock, including any Equity Restructuring or
any securities offering or other similar transaction, for administrative convenience, the Administrator may refuse to permit the exercise of any Award for up to sixty days before or after such transaction. 

  
 6 

 8.4 General. Except as expressly provided in the Plan or the Administrator’s
action under the Plan, no Participant will have any rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number of Shares of any class or dissolution, liquidation, merger, or
consolidation of the Company or other corporation. Except as expressly provided with respect to an Equity Restructuring under Section 8.1 above or the Administrator’s action under the Plan, no issuance by the Company of Shares of any
class, or securities convertible into Shares of any class, will affect, and no adjustment will be made regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the Plan, any Award Agreements
and the Awards granted hereunder will not affect or restrict in any way the Company’s right or power to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its
business, (ii) any merger, consolidation dissolution or liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including securities with rights superior to those of the Shares or securities
convertible into or exchangeable for Shares. The Administrator may treat Participants and Awards (or portions thereof) differently under this Article VIII. 

ARTICLE IX. 
 GENERAL
PROVISIONS APPLICABLE TO AWARDS 
 9.1 Transferability. Except as the Administrator may determine or provide in an Award
Agreement or otherwise for Awards other than Incentive Stock Options, Awards may not be sold, assigned, transferred, pledged or otherwise encumbered, either voluntarily or by operation of law, except by will or the laws of descent and distribution,
or, subject to the Administrator’s consent, pursuant to a domestic relations order, and, during the life of the Participant, will be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, will
include references to a Participant’s authorized transferee that the Administrator specifically approves. 
 9.2 Documentation.
Each Award will be evidenced in an Award Agreement, which may be written or electronic, as the Administrator determines. Each Award may contain terms and conditions in addition to those set forth in the Plan. 

9.3 Discretion. Except as the Plan otherwise provides, each Award may be made alone or in addition or in relation to any other Award.
The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or Awards (or portions thereof) uniformly. 

9.4 Termination of Status. The Administrator will determine how the disability, death, retirement, authorized leave of absence or any
other change or purported change in a Participant’s Service Provider status affects an Award and the extent to which, and the period during which, the Participant, the Participant’s legal representative, conservator, guardian or Designated
Beneficiary may exercise rights under the Award, if applicable. 
 9.5 Withholding. Each Participant must pay the Company, or make
provision satisfactory to the Administrator for payment of, any taxes required by law to be withheld in connection with such Participant’s Awards by the date of the event creating the tax liability. The Company may deduct an amount sufficient
to satisfy such tax obligations based on the applicable statutory withholding rates (or such other rate as may be determined by the Company after considering any accounting consequences or costs) from any payment of any kind otherwise due to a
Participant. Subject to Section 10.8 and any Company insider trading policy (including blackout periods), Participants may satisfy such tax obligations (i) in cash, by wire transfer of immediately available funds, by check made payable to
the order of the Company, provided that the Company may limit the use of the foregoing payment forms if one or more of the payment forms below is permitted, (ii) to the extent permitted by the Administrator, in whole or in part by delivery of
Shares, including Shares retained from the Award creating the tax obligation, valued at their Fair Market Value, (iii) if there is a public market for Shares at the time the tax obligations are satisfied, unless the Company otherwise
determines, (A) delivery (including 

  
 7 

 
telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to deliver promptly to the Company sufficient funds to
satisfy the tax obligations, or (B) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly to the Company cash or a check sufficient to
satisfy the tax withholding; provided that such amount is paid to the Company at such time as may be required by the Administrator, or (iv) to the extent permitted by the Company, any combination of the foregoing payment forms approved by the
Administrator. If any tax withholding obligation will be satisfied under clause (ii) of the immediately preceding sentence by the Company’s retention of Shares from the Award creating the tax obligation and there is a public market for
Shares at the time the tax obligation is satisfied, the Company may elect to instruct any brokerage firm determined acceptable to the Company for such purpose to sell on the applicable Participant’s behalf some or all of the Shares retained and
to remit the proceeds of the sale to the Company or its designee, and each Participant’s acceptance of an Award under the Plan will constitute the Participant’s authorization to the Company and instruction and authorization to such
brokerage firm to complete the transactions described in this sentence. 
 9.6 Amendment of Award; Repricing. The Administrator may
amend, modify or terminate any outstanding Award, including by substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive Stock Option to a
Non-Qualified Stock Option. The Participant’s consent to such action will be required unless (i) the action, taking into account any related action, does not materially and adversely affect the
Participant’s rights under the Award, or (ii) the change is permitted under Article VIII or pursuant to Section 10.6. Notwithstanding the foregoing or anything in the Plan to the contrary, the Administrator may not except
pursuant to Article VIII, without the approval of the stockholders of the Company, reduce the exercise price per share of outstanding Options or Stock Appreciation Rights or cancel outstanding Options or Stock Appreciation Rights in exchange
for cash, other Awards or Options or Stock Appreciation Rights with an exercise price per share that is less than the exercise price per share of the original Options or Stock Appreciation Rights. 

9.7 Conditions on Delivery of Stock. The Company will not be obligated to deliver any Shares under the Plan or remove restrictions from
Shares previously delivered under the Plan until (i) all Award conditions have been met or removed to the Company’s satisfaction, (ii) as determined by the Company, all other legal matters regarding the issuance and delivery of such
Shares have been satisfied, including any applicable securities laws and stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or agreements as the
Administrator deems necessary or appropriate to satisfy any Applicable Laws. The Company’s inability to obtain authority from any regulatory body having jurisdiction, which the Administrator determines is necessary to the lawful issuance and
sale of any securities, will relieve the Company of any liability for failing to issue or sell such Shares as to which such requisite authority has not been obtained. 

9.8 Acceleration. The Administrator may at any time provide that any Award will become immediately vested and fully or partially
exercisable, free of some or all restrictions or conditions, or otherwise fully or partially realizable. 
 9.9 Additional Terms of
Incentive Stock Options. The Administrator may grant Incentive Stock Options only to employees of the Company, any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of the Code,
respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code. If an Incentive Stock Option is granted to a Greater Than 10% Stockholder, the exercise price will not be less than 110% of
the Fair Market Value on the Option’s grant date, and the term of the Option will not exceed five years. All Incentive Stock Options will be subject to and construed consistently with Section 422 of the Code. By accepting an Incentive
Stock Option, the Participant agrees to give prompt notice to the Company of 

  
 8 

 
dispositions or other transfers (other than in connection with a Change in Control) of Shares acquired under the Option made within (i) two years from the grant date of the Option or
(ii) one year after the transfer of such Shares to the Participant, specifying the date of the disposition or other transfer and the amount the Participant realized, in cash, other property, assumption of indebtedness or other consideration, in
such disposition or other transfer. Neither the Company nor the Administrator will be liable to a Participant, or any other party, if an Incentive Stock Option fails or ceases to qualify as an “incentive stock option” under
Section 422 of the Code. Any Incentive Stock Option or portion thereof that fails to qualify as an “incentive stock option” under Section 422 of the Code for any reason, including becoming exercisable with respect to Shares
having a fair market value exceeding the $100,000 limitation under Treasury Regulation Section 1.422-4, will be a Non-Qualified Stock Option. 

ARTICLE X. 

MISCELLANEOUS 
 10.1 No
Right to Employment or Other Status. No person will have any claim or right to be granted an Award, and the grant of an Award will not be construed as giving a Participant the right to continued employment or any other relationship with the
Company. The Company expressly reserves the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan or any Award, except as expressly provided in an Award Agreement.

 10.2 No Rights as Stockholder; Certificates. Subject to the Award Agreement, no Participant or Designated Beneficiary will have any
rights as a stockholder with respect to any Shares to be distributed under an Award until becoming the record holder of such Shares. Notwithstanding any other provision of the Plan, unless the Administrator otherwise determines or Applicable Laws
require, the Company will not be required to deliver to any Participant certificates evidencing Shares issued in connection with any Award and instead such Shares may be recorded in the books of the Company (or, as applicable, its transfer agent or
stock plan administrator). The Company may place legends on stock certificates issued under the Plan that the Administrator deems necessary or appropriate to comply with Applicable Laws. 

10.3 Effective Date and Term of Plan. Unless earlier terminated by the Board, the Plan will become effective on the day prior to the
Public Trading Date and will remain in effect until the tenth anniversary of the earlier of (i) the date the Board adopted the Plan or (ii) the date the Company’s stockholders approved the Plan, but Awards previously granted may
extend beyond that date in accordance with the Plan. If the Plan is not approved by the Company’s stockholders, the Plan will not become effective, no Awards will be granted under the Plan and the Prior Plans will continue in full force and
effect in accordance with their terms. 
 10.4 Amendment of Plan. The Administrator may amend, suspend or terminate the Plan at any
time; provided that no amendment, other than an increase to the Overall Share Limit, may materially and adversely affect any Award outstanding at the time of such amendment without the affected Participant’s consent. No Awards may be granted
under the Plan during any suspension period or after Plan termination. Awards outstanding at the time of any Plan suspension or termination will continue to be governed by the Plan and the Award Agreement, as in effect before such suspension or
termination. The Board will obtain stockholder approval of any Plan amendment to the extent necessary to comply with Applicable Laws. 
 10.5
Provisions for Foreign Participants. The Administrator may modify Awards granted to Participants who are foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in
laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters. 

  
 9 

 10.6 Section 409A. 

(a) General. The Company intends that all Awards be structured to comply with, or be exempt from, Section 409A, such that no
adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Participant’s consent, amend this Plan or Awards,
adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any such actions intended to
(A) exempt this Plan or any Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an Award’s grant date.
The Company makes no representations or warranties as to an Award’s tax treatment under Section 409A or otherwise. The Company will have no obligation under this Section 10.6 or otherwise to avoid the taxes, penalties or interest
under Section 409A with respect to any Award and will have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant “nonqualified deferred
compensation” subject to taxes, penalties or interest under Section 409A. 
 (b) Separation from Service. If an Award
constitutes “nonqualified deferred compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s Service Provider relationship will, to the extent necessary to avoid taxes under
Section 409A, be made only upon the Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the
Participant’s Service Provider relationship. For purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms means a
“separation from service.” 
 (c) Payments to Specified Employees. Notwithstanding any contrary provision in the Plan or any
Award Agreement, any payment(s) of “nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A and as the Administrator determines) due to his or her
“separation from service” will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for the six-month period immediately following such “separation
from service” (or, if earlier, until the specified employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following such six-month period or as soon
as administratively practicable thereafter (without interest). Any payments of “nonqualified deferred compensation” under such Award payable more than six months following the Participant’s “separation from service” will be
paid at the time or times the payments are otherwise scheduled to be made. 
 10.7 Limitations on Liability. Notwithstanding any other
provisions of the Plan, no individual acting as a director, officer, other employee or agent of the Company or any Subsidiary will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss,
liability, or expense incurred in connection with the Plan or any Award, and such individual will not be personally liable with respect to the Plan because of any contract or other instrument executed in his or her capacity as an Administrator,
director, officer, other employee or agent of the Company or any Subsidiary. The Company will indemnify and hold harmless each director, officer, other employee and agent of the Company or any Subsidiary that has been or will be granted or delegated
any duty or power relating to the Plan’s administration or interpretation, against any cost or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval)
arising from any act or omission concerning this Plan unless arising from such person’s own fraud or bad faith. 

  
 10 

 10.8 Lock-Up Period. The Company may, at the
request of any underwriter representative or otherwise, in connection with registering the offering of any Company securities under the Securities Act, prohibit Participants from, directly or indirectly, selling or otherwise transferring any Shares
or other Company securities during a period of up to one hundred eighty days following the effective date of a Company registration statement filed under the Securities Act, or such longer period as determined by the underwriter. 

10.9 Data Privacy. As a condition for receiving any Award, each Participant explicitly and unambiguously consents to the collection, use
and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its Subsidiaries and affiliates exclusively for implementing, administering and managing the Participant’s participation in
the Plan. The Company and its Subsidiaries and affiliates may hold certain personal information about a Participant, including the Participant’s name, address and telephone number; birthdate; social security, insurance number or other
identification number; salary; nationality; job title(s); any Shares held in the Company or its Subsidiaries and affiliates; and Award details, to implement, manage and administer the Plan and Awards (the “Data”). The Company
and its Subsidiaries and affiliates may transfer the Data amongst themselves as necessary to implement, administer and manage a Participant’s participation in the Plan, and the Company and its Subsidiaries and affiliates may transfer the Data
to third parties assisting the Company with Plan implementation, administration and management. These recipients may be located in the Participant’s country, or elsewhere, and the Participant’s country may have different data privacy laws
and protections than the recipients’ country. By accepting an Award, each Participant authorizes such recipients to receive, possess, use, retain and transfer the Data, in electronic or other form, to implement, administer and manage the
Participant’s participation in the Plan, including any required Data transfer to a broker or other third party with whom the Company or the Participant may elect to deposit any Shares. The Data related to a Participant will be held only as long
as necessary to implement, administer, and manage the Participant’s participation in the Plan. A Participant may, at any time, view the Data that the Company holds regarding such Participant, request additional information about the storage and
processing of the Data regarding such Participant, recommend any necessary corrections to the Data regarding the Participant or refuse or withdraw the consents in this Section 10.9 in writing, without cost, by contacting the local human
resources representative. The Company may cancel Participant’s ability to participate in the Plan and, in the Administrator’s discretion, the Participant may forfeit any outstanding Awards if the Participant refuses or withdraws the
consents in this Section 10.9. For more information on the consequences of refusing or withdrawing consent, Participants may contact their local human resources representative. 

10.10 Severability. If any portion of the Plan or any action taken under it is held illegal or invalid for any reason, the illegality or
invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be null and void. 

10.11 Governing Documents. If any contradiction occurs between the Plan and any Award Agreement or other written agreement between a
Participant and the Company (or any Subsidiary) that the Administrator has approved, the Plan will govern, unless it is expressly specified in such Award Agreement or other written document that a specific provision of the Plan will not apply. 

10.12 Governing Law. The Plan and all Awards will be governed by and interpreted in accordance with the laws of the State of Delaware,
disregarding any state’s choice-of-law principles requiring the application of a jurisdiction’s laws other than the State of Delaware. 

  
 11 

 10.13 Claw-back Provisions. All Awards (including any proceeds, gains or other
economic benefit the Participant actually or constructively receives upon receipt or exercise of any Award or the receipt or resale of any Shares underlying the Award) will be subject to any Company claw-back policy, including any claw-back policy
adopted to comply with Applicable Laws (including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder) as set forth in such claw-back policy or the Award Agreement. 

10.14 Titles and Headings. The titles and headings in the Plan are for convenience of reference only and, if any conflict, the
Plan’s text, rather than such titles or headings, will control. 
 10.15 Conformity to Securities Laws. Participant acknowledges
that the Plan is intended to conform to the extent necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws. To the extent Applicable Laws
permit, the Plan and all Award Agreements will be deemed amended as necessary to conform to Applicable Laws. 
 10.16 Relationship to
Other Benefits. No payment under the Plan will be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except as
expressly provided in writing in such other plan or an agreement thereunder. 
 10.17 Broker-Assisted Sales. In the event of a
broker-assisted sale of Shares in connection with the payment of amounts owed by a Participant under or with respect to the Plan or Awards, including amounts to be paid under the final sentence of Section 9.5: (a) any Shares to be sold through
the broker-assisted sale will be sold on the day the payment first becomes due, or as soon thereafter as practicable; (b) such Shares may be sold as part of a block trade with other Participants in the Plan in which all participants receive an
average price; (c) the applicable Participant will be responsible for all broker’s fees and other costs of sale, and by accepting an Award, each Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages,
or expenses relating to any such sale; (d) to the extent the Company or its designee receives proceeds of such sale that exceed the amount owed, the Company will pay such excess in cash to the applicable Participant as soon as reasonably
practicable; (e) the Company and its designees are under no obligation to arrange for such sale at any particular price; and (f) in the event the proceeds of such sale are insufficient to satisfy the Participant’s applicable
obligation, the Participant may be required to pay immediately upon demand to the Company or its designee an amount in cash sufficient to satisfy any remaining portion of the Participant’s obligation.
