Credit) in the amount requested by Landlord (but in no event shall the amount be in excess of Six Hundred Thousand and No/100 Dollars [$600,000.00]) payable to Landlord in the event that Tenant is in default of the Lease as hereby amended,
after the applicable cure period, if any. The Second Letter of Credit shall be issued by a bank approved by Landlord, automatically renew annually, and be in form and content acceptable to Landlord. Landlord and Tenant hereby agree that,

statement for each of the first three calendar years during the Lease term, and (i) if the 2001 statement confirms that Tenants net
income for 2001 meets or exceeds the amount shown on Exhibit C, (ii) if the audited financial statements in 2002 and 2003 confirm that Tenants net income meets or exceeds the previous years, and (iii) if Tenant is not then, and has not
previously been in default under any of the terms of the Lease after the applicable cure period, if any, then Tenants future obligation to renew and provide Landlord with the Original Letter of Credit and the Second Letter of Credit shall,
upon Tenants written request, be waived by the Landlord. Should any of the aforesaid annual financial statements fail to confirm the aforesaid net income requirement, then Tenants obligation to renew and provide Landlord with the
Original Letter of Credit and the Second Letter of Credit shall continue until Tenant has, in three separate years, earned annual net income that meets or exceeds that amount shown for 2001 in Exhibit C, whereupon, subject to (iii) above,
Landlords waiver of such obligation shall occur upon Tenants written request.



8. Tenant represents and warrants that it has not had dealings with any real estate broker, finder or other person, with respect to this Amendment and the Expansion Space in any manner. Tenant shall
indemnify and hold Landlord harmless from any and all damages resulting from any current or future claims that may be asserted against Landlord by any broker, finder or other person, claiming to have dealt with Tenant in connection with this
Amendment and the Expansion Space. The provisions of this paragraph shall survive the termination of this Amendment and the Lease.



9. Except as amended herein, Landlord and Tenant acknowledge and agree that all other terms, conditions and provisions of the Lease not
otherwise inconsistent herewith shall apply to the Expansion Space and the original Premises and otherwise remain in full force and effect. Unless otherwise herein amended, all defined terms from the Lease used herein shall have the same meanings as
used in the Lease.



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

which, in Landlords reasonable opinion, will delay completion of the Premises or the Building. All changes and additions affixed to the

##### Table of Contents



notice of observed defects.
Landlords obligations under this Paragraph shall be deemed to have been performed when Tenant commences to occupy any portion of the Premises for the Permitted Uses except for items which are incomplete or do not conform with the requirements
of this Paragraph and as to which Tenant shall in either case have given written notice to Landlord prior to such commencement. If Tenant has not commenced to occupy the Premises within thirty (30) days after they are deemed ready for occupancy as
provided in this Paragraph, a certificate of completion by Landlords licensed architect or registered engineer shall be conclusive evidence that Landlord has performed all such obligations except for items stated in such certificate to be
incomplete or not in conformity with such requirements.



5. USE. The Premises shall be used solely for the purposes set forth in Paragraph 1.1 of this Lease, but not for any other purpose without Landlords prior written consent. Tenant shall never make any use of the Premises
which is in violation of any governmental laws, rules or regulations, whether now existing or hereafter enacted, or which use is not permitted, or otherwise prohibited, by any restrictive covenants which apply to the Premises. Nor may Tenant make
any use which may or shall constitute a nuisance or trespass, or which increases the fire insurance premiums, or makes such insurance unavailable to Landlord on the Building. In the event of an increase in Landlords fire insurance premiums
which specifically result from Tenants use or occupancy of the Premises, Tenant shall pay Landlord, on demand, the amount of such increase, and failure to do so shall be a default hereunder.



6. RENT. All rent payable by Tenant shall be paid at the address set forth in Paragraph 1.1, shall be without previous demand or notice therefor by Landlord, and paid without set off or deduction. The initial monthly Fixed
Rent payment as set forth in Paragraph 1.1, shall be payable upon the execution hereof and thereafter shall be payable in advance on or before the first day of each calendar month during the Initial Lease Term of this Lease, unless the Initial Lease
Term commences on a day other than the first day of a calendar month, in which event Fixed Rent shall be prorated on a per diem basis at the stated rate for the remainder of the month. In addition to such remedies as may be provided under the
Default provisions of this Lease, Landlord shall be entitled to a late charge of five percent (5%) of the amount of each monthly rent payment not received by the fifth day of the month for which due, and a charge of the lower of the highest lawful
bad check fee or five percent (5%) of the amount of such check given by Tenant when such check is not paid when first presented to the bank on which it is drawn for payment. Additionally, any amount payable to Landlord by Tenant under this Lease,
not paid within five (5) days after its due date in

##### Table of Contents

accordance with the terms of this Lease shall bear interest from such due date until paid in full at the lesser of the highest rate permitted
by applicable law or fifteen percent (15%) per year.



7. ADDITIONAL RENT.



(a)
For each twelve month period following the preceding twelve full months of this Lease, Tenant shall pay as Additional Rent an amount calculated in accordance with the provisions of this Paragraph 7(c), and as otherwise provided herein. Tenant shall
further pay as Additional Rent any sales or use tax that may in the future be imposed on rents collected by Landlord. If any such sales or use tax shall be imposed upon Landlord, and Landlord shall be prohibited by applicable law from collecting the
amount of such tax from Tenant as Additional Rent, then Landlord, upon ninety (90) days prior written notice to Tenant, may terminate this Lease.



(b) Tenants Proportionate Share of Landlords Base Operating Expenses relating to the Building and the Project shall be
calculated by dividing the total rentable square footage of the Premises by the total rentable square footage of the Building and the Project respectively. As of the date hereof, the Tenants Proportionate Share of Landlords Base
Operating Expenses relating to the Building and the Project is as stated in Paragraph 1.1. Landlord may equitably increase or decrease Tenants Proportionate Share of the Project and/or Premises based on the physical size of the Premises, the
Building and/or the Project changing.



(c) Annual
Operating Expense Adjustments. If in any calendar year during the Initial Lease Term hereof, the Landlords Operating Expenses (as defined herein) exceed the Landlords Base Operating Expenses (such excess being hereafter referred to as
the Operating Expense Differential), then as Additional Rent for that year, Tenant shall pay to Landlord, within the time period set forth herein, the Tenants Proportionate Share of the Operating Expense Differential.



Statements showing the actual Landlords Operating
Expenses, and the Tenants proportionate share thereof (hereinafter referred to as the Statement of Actual Adjustment), shall be delivered by Landlord to Tenant after the end of each calendar year in which Additional Rent is paid or
due by Tenant under provisions hereof. Within fifteen (15) days after written notice by Landlord to Tenant of such Statement of Actual Adjustment, Tenant shall pay to Landlord the amount of any Additional Rent shown as being due and unpaid thereon.



Commencing with the first month of the second
full calendar year of the Initial Lease Term, and each and every calendar year thereafter, there shall be added to Tenants monthly payments an amount to cover Tenants Proportionate Share of the Operating Expense Differential for the year
in progress as reasonably estimated by Landlord. Said monthly payments (as estimated by Landlord) shall be paid by Tenant. Should the Statement of Actual Adjustment show the Tenant had paid to



12



---

##### Table of Contents

Landlord an amount that exceeded Tenants Proportionate Share of the actual Landlord Operating Expenses and Tenant is not in default
hereunder or has cured any such default, Landlord shall adjust Tenants rental payments if any credit is shown to be due Tenant, except at the end of the Initial Lease Term at which time should Tenant not renew and vacate any credit due Tenant
shall be refunded by Landlord within thirty (30) days thereafter.



If the final months of this Lease should be less than a full twelve (12) month term, the amount shown as due by Tenant on the Statement of Actual Adjustment shall reflect a proration based on the proportion that the number
of days this Lease was in effect during such lease year bears to 360. Landlords right to recover its Operating Expenses Differential shall survive the termination of this Lease.



If in the twelve-month period preceding the computation of each Operating Expense Differential, the occupancy
of the net rentable area of the Building averages less than ninety-five percent (95%), then it is agreed that the Landlords Operating Expenses will be adjusted for such year so that such Operating Expenses shall be computed as though the net
rentable area of the Building has been ninety-five percent (95%) occupied for such calendar year. All such expense categories will be accounted for and reported on an accrual basis.



The term Landlords Operating Expenses shall include all costs of operation, maintenance,
repair, and management of (i) the Building, (ii) the Project, and (iii) the personal property used in conjunction therewith all as determined by standard accounting practices.



The definition of Landlords Operating Expenses includes, but not by way of limitation, the
following: real estate taxes on the Building; ground rents; if any, installments and interest on assessments for public betterment or public improvements; expenses of any proceedings for abatement of taxes and assessments; premiums for insurance;
reasonable compensation and all fringe benefits, workers compensation insurance premiums and payroll taxes paid by Landlord to, for or with respect to all persons engaged in the operating, maintaining, or cleaning of the Building, provided

equipment (including rental); cost of maintenance, cleaning, and repairs, cost of snowplowing or removal, or both, and care of landscaping; payments to the independent contractors under service contracts for cleaning, operating, managing,
maintaining and repairing the Building (which payments may be to affiliates of Landlord provided the same are at rates consistent with local market practices and with the type of occupancy and the services rendered); reasonable pro rata rental costs
associated with providing the managing

agent space for an office in the office park of which the Building is a part; the Buildings pro rata share (as reasonably determined by
the Landlord) of the cost of operating, maintaining and repairing the common areas and facilities (such as, but not limited to, snowplowing, landscaping, common area and street lighting, security and management); if the Building is located, either
in whole or in part, on a lot which is ground leased, the Buildings pro rata share of all fixed or additional rents or charges payable with respect to such ground lease; and all other necessary expenses paid in connection with the operation,
cleaning, management, maintenance and repair of the Building and Project, or either, and properly chargeable against new income, it being agreed that if Landlord installs a new or replacement capital item for the purpose of reducing Landlords
Operating Expenses, the cost thereof as amortized by Landlord with interest on the unamortized amount shall be included in Landlords Operating Expenses. The Statement of Actual Adjustment shall show the average number of square feet of the
Building which were vacant for the preceding lease year or fraction thereof.



The definition of Landlords Operating Expenses shall exclude, but not by way of limitation, depreciation on the Building in which the Premises are situated or equipment therein,

8. SERVICES BY LANDLORD. Provided that Tenant is not then in default, Landlord shall cause to be furnished to the Premises, in common with other tenants, during normal operating hours as stated in the Rules and Regulations

accommodate such modification safely. If heat generating machines or equipment shall be used in the Premises by Tenant which affect the temperature as normally maintained by the heating and air conditioning system, Landlord shall have the right to

in the Premises to be either cancelled or released pursuant to NCGS 44A-16 within thirty (30) days after such lien has been filed. On termination of this Lease, or vacation of the Premises by Tenant, Tenant shall restore the Premises at
Tenants sole expense to the same condition as existed at the commencement of the Initial Lease Term, ordinary wear and tear and damage by insured casualty only excepted. Landlord, however, may elect to require Tenant to leave alterations made
by Tenant unless at the time of such alterations Landlord agreed in writing they could be removed upon expiration of this Lease.

Except for repairs and replacements that Tenant must make under this Paragraph, Landlord
shall pay for and make all other necessary repairs and replacements to the Premises, the common areas and the Building (including Building fixtures and equipment).



Landlord shall make the repairs and replacements required to maintain the Building in a condition comparable
to other comparable office buildings in the same geographical area. This maintenance shall include, but not be limited to, the roof, foundation, exterior walls, interior structural walls, all structural components, and all systems, such as
mechanical, electrical, HVAC, and plumbing. Repairs or replacements required under this Paragraph shall be made within a reasonable time (depending on the nature of the repair or replacement needed) after receiving notice or having actual knowledge
of the need for such repair or replacement.



Notwithstanding anything to the contrary set forth above in this Paragraph, if Tenant does not perform its maintenance obligations in a timely manner as set forth in this Lease, commencing the same within five (5) days of receipt of
notice from Landlord specifying the work needed and thereafter diligently and continuously pursuing to completion all unfulfilled maintenance obligations, Landlord shall have the right, but not the obligation, to perform such maintenance, and any
amounts so expended by Landlord shall be paid by Tenant to Landlord within thirty (30) days after demand, with interest at the lower of the maximum rate allowed by law or 15% per annum, from the date of expenditure through the date paid.



10. DAMAGES TO PREMISES. If the Premises shall be partially damaged by fire or other casualty insured under Landlords insurance policies, and if Landlords lender(s) shall permit insurance proceeds paid as a result
thereof to be so used, then upon Landlords receipt of the insurance proceeds, Landlord shall, except as otherwise provided herein, promptly repair and restore the same as hereinafter defined (exclusive of trade fixtures, equipment,
furnishings, decorations, signs, and contents); limited, however, to the extent of the insurance proceeds actually received by Landlord. If by reason of such occurrence: (a) the Premises are rendered wholly untenantable; or (b) the Premises are
damaged in whole or in part as a result of a risk which is not covered by Landlords insurance policies; or (c) Landlords lender does not permit a sufficient amount of the insurance proceeds to be used for restoration purposes; or (d) the
Premises are damaged in whole or in part during the last year of the Initial Lease Term; or (e) the Building containing the Premises is damaged (whether or not the Premises are damaged) to an extent of fifty percent (50%) or more of the fair market
value thereof, Landlord may elect either to repair the damage as aforesaid within one hundred twenty (120) days of damage, or to cancel this Lease by written notice of cancellation given to Tenant within sixty (60) days after the date of such
occurrence, and thereupon this Lease

shall terminate. Tenant shall vacate and surrender the Premises to Landlord within thirty (30) days after receipt of such notice of
termination. In addition, Tenant may also terminate this Lease by written notice given to Landlord at any time between the one hundred twenty-first (121st) and one hundred fiftieth (150th) day after the occurrence of any such casualty, if Landlord
has failed to restore the damaged portions of the Building (including the Premises) within one hundred twenty (120) days of such casualty. However, if Landlord is prevented by strike, act of God, unavailability of materials, weather, Tenant induced
delays or other cause beyond its reasonable control, from completing the restoration within said one hundred twenty (120) day period, then Landlord shall have an additional period beyond said one hundred twenty (120) days, equal to the period
Landlord is delayed by causes beyond its reasonable control, in which to restore the damaged areas of the Building; and Tenant may not elect to terminate this Lease until said additional period required for completion has expired with the Building
not having been substantially restored. In such case, Tenants termination period shall begin to run upon the expiration of Landlords additional period for restoration set forth in the preceding sentence. Upon the termination of this
Lease as aforesaid, Tenants liability for all rent and other charges reserved hereunder shall cease as of the effective date of the termination of this Lease, subject, however, to the provisions for the prior abatement of Rent hereinafter set
forth.



Unless this Lease is terminated as
aforesaid, this Lease shall remain in full force and effect, and Tenant shall promptly repair, restore, or replace Tenants improvements, trade fixtures, decorations, signs, and contents in the Premises in a manner and to a condition
substantially equal to that existing prior to their damage or destruction, and the proceeds of all insurance carried by Tenant on said property shall be held in trust by Tenant for the purposes of such repair, restoration, or replacement.



If, by reason of such fire or other casualty,
the Premises are rendered wholly untenantable, all rent and other charges payable by Tenant shall be fully abated, or if only partially damaged, such Rent and other charges shall be abated proportionately as to that portion of the Premises rendered
untenantable, in either event (unless the Lease is terminated, as aforesaid) from the date of such casualty until fifteen (15) days after notice by Landlord to Tenant that the Premises have been substantially repaired and restored, or until Tenant
resumes or can resume its normal business operations in the Premises, whichever shall first occur. Tenant shall continue the operation of Tenants business in the Premises or any part thereof not so damaged during any such period to the extent
reasonably practicable from the standpoint of prudent business management, except for such abatement of Rent and other charges as hereinabove set forth. However, if such damages or other



18

##### Table of Contents

casualty were caused by the gross negligence or other wrongful conduct of Tenant or of Tenants subtenants, licensees, contractors, or
invitees, or their respective agents or employees, there shall be no abatement of Rent or other charges. Except for the abatement of the Rent and other charges hereinabove set forth, Tenant shall not be entitled to, and hereby waives, all claims
against Landlord for any compensation or damage for loss of use of the whole or any part of the Premises and/or for any inconvenience or annoyance occasioned by any such damage, destruction, repair, or restoration.



As used in this Paragraph, restoration,
restored, substantially restored, or substantially repaired and restored shall be deemed to mean the Premises have been put in substantially the same quality and condition as existed immediately prior to such
damage or destruction, is habitable for Tenants intended use, and is evidenced by the issuance of a certificate of occupancy by the appropriate governmental authority.



11. ASSIGNMENT - SUBLEASE. Tenant may not assign or encumber this Lease or its interest in the Premises or any part thereof arising under this Lease, and may not sublet any part or all of the Premises without the prior written
consent of Landlord, which consent shall not be unreasonably withheld and provided that any proposed subtenant or assignee qualifies as a Permitted Tenant (as hereinafter defined). It shall not be deemed unreasonable for Landlord to withhold its
consent under the following conditions:



(i) The
assignee or sublessee does not have a net worth calculated according to generally accepted accounting principles at least equal to the greater of the net worth of Tenant immediately prior to such assignment or sublease or the net worth of the Tenant
at the time it executed the Lease;



(ii) The
intended use of the Premises by the assignee or sublessee is not reasonably satisfactory to Landlord;



(iii) The intended use of the Premises by the assignee or sublessee would materially increase the pedestrian or vehicular traffic to the
Premises or the Project;



(iv) Occupancy of the
Premises by the assignee or sublessee would, in Landlords opinion, violate any agreement binding upon Landlord or the Project with regard to the identity of tenants, usage in the Project, or similar matters;



(v) The identity or business reputation of the assignee or
sublessee will, in good faith judgment of Landlord, tend to damage the goodwill or reputation of the Project;



(vi) The assignment or sublet is to another tenant in the Project and is at rates which are below those charged by Landlord for comparable
space in the Project;



(vii) In the case of a
sublease, the subtenant has not acknowledged that the Lease controls over any inconsistent provision in the sublease; or



19

##### Table of Contents



(viii) The
proposed assignee or sublessee is a government entity.



Any
assignment or sublease to which Landlord may consent (one consent not being any basis that Landlord should consent grant any further consent) shall not relieve Tenant of any of its obligations hereunder.



Because of obligations imposed upon Landlord under that
certain Office Building Ground Lease Agreement dated as of January 1, 1998 (the Ground Lease) with The Board of Trustees of the Endowment Fund of North Carolina State University (the Ground Lessor) Tenant acknowledges and
accepts that as a condition of any sublease or assignment, the business of such subtenant or assignee must at all times and in some way be connected or associated with the University such that said subtenant or assignee would be qualified to lease
space directly from North Carolina State University (the University) in accordance with the Universitys policies for leasing to tenants on Centennial Campus (a Permitted Tenant). In the event of a dispute concerning the
qualifications of a subtenant or assignee, the question will be presented to the Universitys Vice Chancellor for Research, Outreach, Extension and Economic Development for a decision. Should the subtenant or assignee be dissatisfied with the
decision of the Vice Chancellor, the subtenant or assignee shall have the right to submit the question to the Chancellor of the University, whose decision shall be final. Notwithstanding the foregoing, the Ground Lessor has agreed that: (a) it will
not deny Permitted Tenant status to any applicant for such status for reasons other than failure to meet the criteria generally applicable to other prospective tenants within Centennial Campus; and (b) any applicant for Permitted Tenant status
which, at the time of such application, is already a tenant in good standing in Centennial Campus shall be granted Permitted Tenant status automatically.



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



If this Lease shall 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, attributable to the Premises or portion
thereof so assigned or sublet, then one-half of any such excess, after deducting the costs of assignment or subletting incurred by Tenant (e.g., upfitting expense, commissions, legal costs, etc.), shall be paid over to Landlord by Tenant, and
refusal of Tenant to so agree shall be grounds based on which Landlord may withhold its consent to any sublease or assignment.

12. TENANTS COMPLIANCE-INSURANCE REQUIREMENTS. Tenant shall comply with all applicable laws, ordinances and regulations affecting the Premises, now existing or hereafter adopted, including general rules and regulations
for tenants (a copy of the present rules are attached as Exhibit C) as may be developed from time to time by Landlord and either delivered to Tenant or posted on the Premises. Landlord agrees that its rules and regulations will be enforced in
a non-discriminatory manner as to all tenants.



Throughout the Initial Lease Term of this Lease, Tenant at its sole cost and expense shall keep or cause to be kept for the mutual benefit of Landlord, Landlords managing agent (presently Craig Davis Properties, Inc.) and
Tenant public liability and property damage insurance with combined single limit coverage of at least $1,000,000.00 (with appropriate cross-liability endorsements so showing). Such policies shall insure against all liability of Tenant, Tenants
authorized representatives, and anyone for whom Tenant is responsible, arising out of and in connection with Tenants use of the Premises, and shall insure Tenants performance of the indemnity provisions contained herein. Tenant shall
also have adequate business interruption insurance and insure its personal property and fixtures located in the Premises and any improvements made by Tenant for their full insurable value, and Tenant shall neither have, nor make, any claim against
Landlord for any loss or damage to the same, regardless of the cause thereof.



Prior to taking possession of the Premises, and thereafter at least thirty (30) business days prior to the renewal dates thereof, Tenant shall deliver to Landlord copies of original policies, or
satisfactory certificates thereof, and a receipt showing payment of the next years premium. All such policies shall be non-assessable and shall contain language that: (A) any loss shall be payable notwithstanding any act or negligence of
Landlord or Tenant that might otherwise result in forfeiture of the insurance, (B) the policies are primary and non-contributing with any insurance that Landlord may carry, and (C) the policies cannot be cancelled or changed except after thirty (30)
days prior written notice to Landlord.



Anything in this Lease to the contrary notwithstanding, Landlord hereby releases and waives unto Tenant (including all partners, stockholders, members, managers, officers, directors, employees and agents thereof), its successors and
assigns, and Tenant hereby releases and waives unto Landlord (including all partners, stockholders, members, managers, officers, directors, employees and agents thereof), its successors and assigns, all rights to claim damages for any injury, loss,
cost or damage to persons or to the Premises or any other casualty, as long as the amount of such injury, loss, cost or damage has been paid either to Landlord, Tenant, or any other person, firm or corporation, under the terms of any fire, extended
coverage, public liability or other policy of insurance, to the extent



21



---

##### Table of Contents

such releases or waivers are permitted under applicable law. All policies of insurance carried or maintained pursuant to this Lease shall
contain, or be endorsed to contain, a provision whereby the insurer waives all rights of subrogation against either Tenant or Landlord.



Subject to the terms of the preceding paragraph, Tenant shall indemnify and hold Landlord harmless from and against any and all claims
arising out of (a) Tenants use of the Premises or any part thereof, (b) any activity, work, or other thing done, permitted or suffered by Tenant in or about the Premises or the Building, or any part thereof, (c) any breach or default by Tenant
in the performance of any of its obligations under this Lease, or (d) any act or negligence of Tenant, or any partner, shareholder, member, manager, officer, agent, employee, contractor, servant, invitee or guest of Tenant; and in each case from and
against any and all damages, losses, liabilities, lawsuits, costs and expenses (including attorneys fees at all tribunal levels) arising in connection with any such claim or claims as described in (a) through (d) above, or any action brought
thereon, except for Landlords gross negligence or willful misconduct. If such action shall be brought against Landlord, Tenant upon notice from Landlord shall defend the same through counsel selected by Tenants insurer, or other counsel,
which counsel in either case must be reasonably acceptable to Landlord. Tenant assumes all risk of damage or loss to its property or injury or death to persons in, on, or about the Premises, from all causes except those for which the law imposes
liability on Landlord, regardless of any attempted waiver thereof, and Tenant hereby waives such claims in respect thereof against Landlord, except for Landlords gross negligence or willful misconduct. The provisions of this paragraph shall
survive the termination of this Lease.



Landlord
shall keep the Building, including but not limited to the improvements per the Complete Plans, insured against damage and destruction by fire, extended coverage peril, vandalism, and other perils in the amount of the full replacement value of the
Building, as the value may exist from time to time.



Each party shall keep its personal property and trade fixtures in the Premises and Building insured with all risks insurance covering one hundred (100) percent of the replacement cost of the property and fixtures. Tenant
shall also keep any post-occupancy improvements made to the Premises at Tenants request following occupancy insured to the same degree as Tenants personal property. The amounts of insurance coverage required by this Lease are subject to
review at the end of each three-year period following the Term Commencement Date. At each review, if necessary to maintain the same level of coverage that existed on the Term Commencement Date, the amounts of coverage shall be increased to the
lesser of: (i) the amounts of coverage carried by prudent landlords and tenants of comparable first class office buildings in the Wake, Durham and Orange



22



---

##### Table of Contents

County, North Carolina area; or (ii) twenty-five (25) percent higher than the previous insurance amounts.



Tenants insurance policies required by this Lease shall:
(i) be issued by insurance companies licensed to do business in the state of North Carolina with general policyholders ratings of at least A- and a financial size category of at least VIII in the most current Bests Key Rating
Guide available on the Term Commencement Date (if the Bests ratings are changed or discontinued, the parties shall agree to an equivalent method of rating insurance companies); (ii) name the nonprocuring party and Landlords
managing agent as additional insureds as their interest may appear; (iii) provide that the insurance not be canceled or materially changed in the scope or amount of coverage unless thirty (30) days advance notice is given to the nonprocuring
party; (iv) be primary policiesnot as contributing with, or in excess of, the coverage that the other party may carry; (v) provide that any loss shall be payable notwithstanding any act or negligence of Landlord or Tenant which might result in
a forfeiture thereunder of such insurance or the amount of proceeds payable; (vi) have deductibles not greater than $1,000.00; and (vii) be maintained during the entire Initial Lease Term and any extension or renewal thereof.



By the Term Commencement Date and upon each renewal of its
insurance policies, each party shall give certificates of insurance to the other party. The certificate shall specify amounts, types of coverage, the waiver of subrogation, and the insurance criteria listed in this paragraph. The policies shall be
renewed or replaced and maintained by the party responsible for that policy. If either party fails to give the required certificate within thirty (30) days after notice of demand for it, the other party may obtain and pay for that insurance and be
entitled to receive immediate reimbursement from the party required to have the insurance.



13. SUBORDINATION-ATTORNMENT - LANDLORD FINANCING. Tenant agrees that this Lease will be either subordinate or superior to any mortgage heretofore or hereafter executed by Landlord covering the Premises, depending on the
requirements of such mortgagee. Tenant, within ten (10) days of request to do so from Landlord or its mortgagee, will execute an agreement making this Lease superior or subordinate and containing such other covenants on Tenants part as
Landlords mortgagee may reasonably request. Tenant will agree to attorn to said mortgagee provided the mortgagee agrees not to disturb Tenants possession hereunder so long as Tenant is in compliance with this Lease. Landlord consents to
Tenants execution of Landlords mortgagees subordination, attornment and non-disturbance agreement, and to be bound by the provisions thereof. Further, Tenant agrees to execute within ten (10) days of request therefor, and as often
as requested, estoppel certificates confirming any factual matter requested therein which is



23

##### Table of Contents

true and is within Tenants knowledge regarding this Lease, the Premises, or Tenants use thereof, including, but not limited to,
date of occupancy, termination date of this Lease, the amount of rent due and date to which rent is paid, whether or not Tenant has any defense or offsets to the enforcement of this Lease or the rent payable hereunder or knowledge of any default or
breach by Landlord, and that this Lease is in full force and effect except as to any modifications or amendments, copies of which Tenant shall attach to such estoppel certificate. Tenants obligation to furnish each estoppel certificate in a
timely fashion is a material inducement for Landlords execution of this Lease and Tenants failure to timely furnish said estoppel will constitute an event of default under this Lease. No cure or grace period provided in this Lease shall
apply to Tenants obligations to timely deliver an estoppel certificate.



Tenant agrees to give any mortgagee of Landlord which has provided a non-disturbance agreement to Tenant, notice of, and a reasonable opportunity to cure (which shall in no event be less than thirty
(30) days after written notice thereof delivered to mortgagee as herein provided) any Landlord default hereunder; and Tenant agrees to accept such cure if effected by such mortgagee. No termination of this Lease by Tenant shall be effective until
such notice has been given and unless such cure period has expired without such default having been cured. Further Tenant agrees to permit such mortgagee (or other purchaser at any foreclosure sale), and its successors and assigns, on acquiring
Landlords interest in the Premises and the Lease, to become substitute Landlord hereunder, with liability only for such Landlord obligations as accrue after Landlords interest is so acquired.



14. SIGNS. Tenant may not erect, install or display any sign or advertising material upon the Building exterior, the exterior of the Premises, or the exterior walls thereof, or in any window therein, without the prior written
consent of Landlord, excluding suite entry and monument signage hereby approved by Landlord. Landlord shall furnish, install and maintain a Building directory at a location in or near the lobby listing the name of Tenant and the room number of
Tenants entrance.



15. ACCESS TO PREMISES. Landlord shall have the right, either itself or through its authorized agents, to enter the Premises at all reasonable times for inspection to show prospective tenants within one hundred eighty
(180) days of the termination date hereof, as extended by an exercised option, to allow inspection by mortgagees, and to make such repairs, alterations or changes as Landlord deems necessary, with reasonable advance notice where possible. Tenant,
its agents, employees, invitees, and guests, shall have the right of ingress and egress to common and public



24

##### Table of Contents

areas of the Building, provided Landlord by reasonable regulation may control such access for the comfort, convenience, safety and protection
of all tenants in the Building.



16. DEFAULT. If Tenant: (A) fails to pay within five (5) days of its due date any rent or other sums which Tenant is obligated to pay as provided herein; or (B) breaches any other agreement, covenant or obligation
herein set forth and within fifteen (15) days after notice thereof fails to commence to cure such breach, or diligently prosecute to complete cure such breach after commencing cure; or (C) files (or has filed against it) any petition or action for
relief under any creditors law (including bankruptcy, reorganization, or similar actions), either in state or federal court; or (D) becomes insolvent, makes any transfer in fraud of creditors, has a receiver appointed for its assets, or makes
an assignment for benefit of creditors, then Tenant shall be in default hereunder, and, in addition to any other lawful right or remedy which it may have, Landlord, without notice to Tenant, may do any one or more of the following: (i) terminate
this Lease; or (ii) repossess the Premises, and with or without terminating, relet the same at such amount as Landlord deems reasonable, and if the amount is less than Tenants rent, Tenant shall immediately pay the difference on demand to
Landlord, but if in excess of Tenants rent and other monetary obligations hereunder, the entire amount shall belong to Landlord free of any claim of Tenant thereof. All expenses of Landlord in repairing, restoring or altering the Premises for
reletting, together with leasing fees and all other expenses in seeking and obtaining a new tenant, shall be charged to and become a liability of Tenant. Landlords actual attorneys fees in pursuing any of the foregoing remedies, or in
collecting any rents due by Tenant, shall be paid by Tenant.



Tenant further agrees that Landlord may obtain an order for summary ejectment from any court of competent jurisdiction without prejudice to Landlords rights to otherwise collect rents from Tenant.



All rights and remedies of Landlord are cumulative, and the
exercise of any one shall not be an election excluding Landlord at any other time from exercise of a different or inconsistent remedy. No exercise by Landlord of any right or remedy granted herein shall constitute or effect a termination of this
Lease unless Landlord shall so elect by written notice delivered to Tenant.



No waiver by Landlord of any covenant or condition shall be deemed to imply or constitute a further waiver of the same at a later time, and acceptance of rent by Landlord, even with knowledge of a
default by Tenant, shall not constitute a waiver of such default.



17. PROPERTY OF TENANT. Tenant shall timely pay any and all taxes levied or assessed against or upon Tenants equipment, fixtures, furniture, leasehold improvements, and personal property located in the Premises.
Tenant, if not in default hereunder, and prior to the



25



---

##### Table of Contents

expiration date of this Lease, may remove all fixtures and equipment which it has placed in the Premises, provided Tenant repairs all damages
caused by such removal. If Tenant does not remove its property from the Premises upon termination (for whatever cause) of this Lease, such property shall be deemed abandoned by Tenant, and Landlord may dispose of the same in whatever manner Landlord
may elect, with no obligation to account to Tenant for same.



18. EMINENT DOMAIN. If all of the Premises, or such part thereof as will make the same unusable for the purposes contemplated by this Lease, be taken under the power of eminent domain (or a conveyance in lieu thereof),
then this Lease shall terminate as of the date possession is taken by the condemnor, and rent shall be adjusted between Landlord and Tenant as of such date. If only a portion of the Premises are taken and Tenant can continue use of the remainder for
the intended use of Tenant and its invitees, then this Lease will not terminate, but rent shall abate in a just and proportionate amount to the loss of use occasioned by the taking. Tenant shall have no right or claim to any part of any award made
to or received by Landlord for any taking and no right or claim for any alleged value of the unexpired portion of this Lease; provided, however, that Tenant shall not be prevented from making a claim against the condemning party (but not against
Landlord) for any moving expenses, loss of profits, or taking of Tenants personal property (other than its leasehold estate) to which Tenant may be entitled.



19. QUIET ENJOYMENT. If Tenant promptly and punctually complies with each of its obligations hereunder, it shall peacefully have and enjoy the possession of the Premises during the Initial Lease Term or any renewal
thereof, provided that no action of Landlord or other tenants in working in other space in the Building, or in repairing or restoring the Premises, shall be deemed a breach of this covenant, or give to Tenant any right to modify this Lease either as
to term, rent payable, or other obligations to be performed.



20. SECURITY DEPOSIT. Landlord shall retain the Security Deposit as security for the performance by Tenant of each of its obligations hereunder. If Tenant fails at any time to perform its obligations, Landlord may at
its option apply said deposit, or so much thereof as is required, to cure Tenants default, but if prior to the termination of this Lease Landlord depletes said deposit in whole or in part, Tenant shall immediately restore the amount so used by
Landlord. This deposit shall not bear interest and unless Landlord uses the same to cure a default of Tenant, or to restore the Premises to the condition that Tenant is required to leave them at the conclusion of the term, Landlord shall within
thirty (30) days of the termination of this Lease refund to Tenant so much of the deposit as it continues to hold.

21. NOTICES. All notices which may or are required to be given under this Lease shall be in writing and may be delivered in either of the following ways: by personal service; by certified, registered or express United
States mail, postage prepaid, return receipt requested; by overnight courier services such as Federal Express; or by facsimile transmission with receipt confirmation, and addressed or sent to the party to be notified at the applicable address set
forth in Paragraph 1.1 hereof, or to such other address (or facsimile number) as a party may specify by notice duly given. Notices given in the foregoing manner shall be effective (except as provided in the next succeeding paragraph) when personally
delivered, if mailed on the earlier of the date actually received or three business days after deposited in the United States mail, the next business day if sent by overnight courier, and the date the facsimile transmission is received on a business
day, if before noon, otherwise on the next succeeding business day.



Notice of a change of address or facsimile number shall be given in writing to the other party as provided above, but shall not be effective until ten (10) days after receipt. Notices may be given on behalf of any party by
such partys legal counsel.



22. HOLDING OVER. If Tenant shall hold over after the expiration of the Initial Lease Term or other termination of this Lease, such holding over shall not be deemed to be a renewal of this Lease but shall be deemed to
create a tenancy-at-sufferance and by such holding over Tenant shall be deemed to have agreed to be bound by all of the terms and conditions of this Lease, except those as to the term hereof, and during such tenancy-at-sufferance, Tenant shall pay
to Landlord (A) Fixed Rent at the rate equal to two hundred percent (200%) of that provided for in Paragraph 1.1 (as such rental amount may have been increased in accordance with Paragraph 7 or otherwise), and (B) any and all operating expenses or
other forms of additional rent payable under the terms of this Lease. The increased rental during such holding over is intended to partially compensate Landlord for losses, damages and expenses, including frustrating and delaying Landlords
ability to secure a replacement tenant.



23. BROKERS COMMISSIONS. Tenant represents and warrants that it has not had dealings with any real estate broker, finder or other person, with respect to this Lease in any manner, except for the Tenants
Broker, if any, identified in Paragraph 1.1 hereof. Landlord shall pay any commissions or fees that are payable to said Broker and the Landlords Broker with respect to this Lease pursuant to separate agreements that it has with one or both of
them. Tenant shall indemnify and hold Landlord harmless from any and all damages resulting from any current or future claims that may be asserted against Landlord by any other broker, finder or other person, claiming to have

dealt with Tenant in connection with this Lease. The provisions of this paragraph shall survive the termination of this Lease.



24. ENVIRONMENTAL COMPLIANCE.



(A) Tenant shall not cause or permit any Hazardous Material (as hereinafter defined) to be used, stored, generated or disposed of on or in the Premises by Tenant, Tenants agents, subtenants, employees, contractors or invitees,
except in conformity with all applicable legal requirements. If Hazardous Materials are used, stored, generated or disposed of on or in the Premises, except as permitted above, or if the Premises become contaminated in any manner for which Tenant is
legally liable, Tenant shall indemnify and hold harmless the Landlord from any and all claims, damages, fines, judgments, penalties, costs, liabilities or losses arising during or after the Initial Lease Term and arising as a result of such
contamination by Tenant. This indemnification includes, without limitation, any and all costs incurred due to any investigation of the site or any cleanup, removal or restoration mandated by a federal, state or local agency or political subdivision.
Without limitation of the foregoing, if Tenant causes or permits the presence of any Hazardous Materials on the Premises in violation of any applicable legal requirements, and such results in contamination, Tenant shall promptly, at its sole
expense, take any and all necessary actions to return the Premises to the condition existing prior to the presence of any such Hazardous Materials on the Premises. Tenant shall first obtain Landlords approval for any such remedial action.



(B) Landlord warrants and represents that, to
its best knowledge, no use, storage, treatment or transportation of Hazardous Materials has occurred in or on the Premises prior to the date hereof in violation of any applicable federal, state and local laws, regulations and ordinances. Landlord
additionally warrants and represents that, to its best knowledge, no release, leak, discharge, spill, disposal or emission of Hazardous Materials has occurred in, on or under the Premises, and that the Premises are free of Hazardous Materials as of
the date hereof. Tenant shall have the right within thirty (30) days after the execution of this Lease to conduct an environmental examination of the Premises and if such examination shall reveal any Hazardous Materials, Landlord shall have the
right to remediate such Hazardous Materials at its own expense or to refuse to do so and if Landlord shall refuse to remediate such Hazardous Materials, Tenant shall have the right to terminate this Lease and have any rent paid refunded to Tenant.
Landlord shall indemnify and hold harmless the Tenant from any and all claims, damages, fines, judgments, penalties, costs, liabilities or losses arising prior to, during or after the Initial Lease Term and arising as a result of such contamination
by Landlord. This indemnification includes, without limitation, any and all costs

##### Table of Contents

incurred due to any investigation of the site or any cleanup, removal or restoration mandated by a federal, state or local agency or
political subdivision.



(C) Tenant shall not
cause or permit any Hazardous Material to be brought upon, kept, or used in or about the Premises, or the Building and related Improvements by Tenant, its subtenants, agents, employees, contractors, or invitees, except for such Hazardous Material as
is necessary for the operation of the Premises for the uses permitted under this Lease. Any Hazardous Material permitted on the Premises as provided under this subparagraph (C) and all containers therefor, shall be used, kept, stored, transported or
disposed of in a manner that complies with all federal, state, and local laws and regulations applicable to such Hazardous Material.



(D) Tenant shall not cause or permit any discharge, spill, leak, emit, dispose of, or permit to be discharged, spilled, leaked, emitted,
or disposed of any material on, at, or in the Leased Premises or the Building or into the atmosphere, ground, sewer system, or any body of water, contrary to any applicable legal requirements by Tenant, its subtenants, agents, employees, contractors
or invitees if that material (including without limitation materials which may be so determined by any governmental authority or so designated by notice from the Landlord to the Tenant) does or may pollute or contaminate the same, or may adversely

the office park where the Building is located before the Term Commencement Date or at any time during the term or any extension of this Lease. Insofar as reasonably possible, the Substitute Premises shall have a comparable square foot area and a
configuration substantially similar to the Premises. Landlord shall give Tenant at least sixty (60) days written notice of its intention to relocate Tenant to the Substitute Premises. This notice will be accompanied by a floor plan of the Substitute
Premises. After such notice, Tenant shall have ten (10) days within which to agree with Landlord on the proposed new space and unless such



30



---

##### Table of Contents

agreement is reached within such period of time, this Lease may be terminated by Landlord at the end of the sixty (60) day period of time
following the aforesaid notice. Landlord agrees to construct or alter, at its own expense, the Substitute Premises as expeditiously as possible so that they are in substantially the same condition that the Premises were in immediately prior to the
relocation. Landlord shall have the right to reuse the fixtures, improvements, and alterations used in the Premises. Tenant agrees to occupy the Substitute Premises as soon as the Landlords work is substantially completed and a certificate of
occupancy is issued for the Substitute Premises. Landlord shall pay Tenants reasonable cost of moving Tenants furnishings, trade fixtures, and inventory to the Substitute Premises.



Except as provided herein, Tenant agrees that all of the
obligations of this Lease, including the payment of rent, will continue despite Tenants relocation to the Substitute Premises. Upon substantial completion of the Substitute Premises, this Lease will apply to the Substitute Premises as if the
Substitute Premises had been the space originally described in the Lease. Landlord shall use all reasonable efforts to minimize any period when the Premises shall be closed to the public as a result of the relocation.



26. MISCELLANEOUS. Headings of paragraphs are for convenience only and shall not be considered in construing the meaning of the contents of such paragraph. The invalidity of any portion of this Lease shall not have any
effect on the balance hereof. Should either party institute any legal proceedings against the other party for breach of any provision herein contained, and prevail in such action, the losing (guilty) party shall in addition be liable for the costs
and expenses of the prevailing party, including its reasonable attorneys fees (at all tribunal levels). This Lease shall be binding upon the respective parties hereto, and upon their heirs, executors, successors and assigns. This Lease
supersedes and cancels all prior negotiations between the parties, and no changes shall be effective unless in writing signed by the party affected by such change. Time is of the essence as to the performance of Tenants obligations under this
Lease. Landlord reserves the right to promulgate (and change from time to time) reasonable regulations it deems appropriate for the common use and benefit of all tenants, with which regulations Tenant shall comply. Landlord may sell the Premises or
the Building without affecting the obligations of Tenant hereunder; upon the sale of the Premises or the Building, Landlord shall be relieved of all responsibility for the Premises and shall be released from any liability thereafter accruing under
this Lease. If any security deposit or prepaid rent has been paid by Tenant, Landlord may transfer the security deposit or prepaid rent to Landlords successor. Tenant agrees to attorn to any successor to Landlord. This Lease may not be
recorded, but a memorandum of this Lease may be recorded by either party, and



31

##### Table of Contents

either party agrees on request of the other party to execute a memorandum hereof for recording purposes. The singular shall include the
plural, and the masculine, feminine or neuter includes the other. If Landlord, or its employees, officer, directors, members, managers, stockholders or partners are ordered to pay Tenant a money judgment because of Landlords default under this
Lease, said money judgment may only be enforced against and satisfied out of: (i) Landlords interest in the Building in which the Premises are located including the rental income and proceeds from sale; and (ii) any insurance or condemnation
proceeds received because of damage or condemnation to, or of, said Building that are available for use by Landlord. No other assets of Landlord or said other parties exculpated by the preceding sentence shall be liable for, or subject to, any such
money judgment. In the event of a conflict between this Lease and the Ground Lease, the terms and conditions of the Ground Lease shall control. If Tenant is a corporation, trust, limited liability company or general or limited partnership, Tenant,
and each individual executing this Lease on behalf of such entity, represent and warrant to Landlord that such individual is duly authorized to execute and deliver this Lease on behalf of said entity. This Lease and the rights and obligations of the
parties hereto shall be interpreted, construed and enforced in accordance with the laws of the State of North Carolina.
