Section 1.02. Leased Premises. Landlord hereby leases to Tenant and Tenant
leases from Landlord, under the terms and conditions herein, the Leased Premises.

ARTICLE 2 - TERM AND POSSESSION

Section 2.01. Term. The term of this Lease (Lease Term) shall be for the period of time set forth in
Section 1.01F hereof and shall commence on the Commencement Date set forth in Section 1.01G hereof.

Section 2.02. Construction of Tenant Improvements.

(a) Tenant Improvements. Tenant has personally
inspected the Leased Premises and except as otherwise set forth in Section 7.02 hereof, accepts the same AS IS without representation or warranty by Landlord of any kind and with the understanding that Landlord shall
have no responsibility with respect thereto except to construct in a good and workmanlike manner the tenant finish improvements set forth in the scope of work (the Scope of Work) attached hereto as Exhibit B and made a part
hereof (the Tenant Improvements), which improvements shall be constructed at the shared expense of Landlord and Tenant as indicated on Exhibit B attached hereto and as follows: (i) Tenant shall contribute Seven
Hundred Ninety Seven Thousand Two Hundred Seventy Nine and 11/100 Dollars (797,279.11) (Tenants Contribution) towards the cost of the Tenant Improvements described in the Scope of Work attached hereto as Exhibit
B, which Tenants Contribution shall be paid to Landlord as follows: (A) one-half of the Tenants Contribution shall be paid by Tenant to Landlord within five (5) days following the mutual execution of this Lease by Landlord
and Tenant, and (B) following Substantial Completion of the Tenant Improvements, Tenant shall pay to Landlord the balance of Tenants Contribution within ten (10) days of Landlords written request therefore and prior to
Tenants occupancy of the Leased Premises; and (ii) all costs in excess of the Tenants Contribution associated with construction of the Tenant Improvements described in the Scope of Work attached hereto as Exhibit B shall be
paid by Landlord. Tenant acknowledges and agrees that (i) the cost to construct and install the Tenant Improvements shall include a fee payable to the projects construction manager or general contractor, (ii) that such construction
manager or general contractor may be a subsidiary, affiliate or employees of Landlord, and (iii) said fee shall be included in the Tenants Contribution. Tenants failure to deliver the payments required in this paragraph shall
entitle Landlord to stop the construction and installation of the Tenant Improvements until such payment is received, and any resulting delay shall constitute a Tenant Delay (as hereinafter defined) hereunder. In addition, all delinquent payments
shall accrue interest at 15% per annum.

(b) Plans and Specifications. Within ten (10) days after the date of execution of
this Lease by Landlord and Tenant, Landlord shall prepare and submit to Tenant a set of plans and specifications and/or construction drawings (the Plans and Specifications) covering all work to be performed by Landlord in
constructing the leasehold improvements to the Leased Premises, which shall be based on the



---

Scope of Work attached as Exhibit B hereto. Tenant shall have three (3) business days after receipt of the
Plans and Specifications in which to review the Plans and Specifications and to give Landlord written notice of Tenants approval of the Plans and Specifications or its requested changes to the Plans and Specifications. Tenant shall have no
right to request any leasehold improvements or any changes to the Plans and Specifications which would materially alter the Leased Premises, the exterior appearance or basic nature of the Building, or the Building systems. If Tenant fails to approve
or request changes to the Plans and Specifications within three (3) business days after its receipt of the Plans and Specifications, then Tenant shall be deemed to have approved the Plans and Specifications and the same shall thereupon be
final. If Tenant requests any changes to the Plans and Specifications, Landlord shall make those changes which are reasonably requested by Tenant and shall within three (3) business days of its receipt of such request submit the revised portion
of the Plans and Specifications to Tenant. Tenant may not thereafter disapprove the revised portions of the Plans and Specifications unless Landlord has unreasonably failed to incorporate reasonable comments of Tenant and, subject to the foregoing,
the Plans and Specifications, as modified by said revisions, shall be deemed to be final upon the submission of said revisions to Tenant. Tenant shall at all times in its review of the Plans and Specifications, and of any revisions thereto, act
reasonably and in good faith. Without limiting the foregoing, Tenant agrees to confirm Tenants consent to the Plans and Specifications in writing within three (3) business days following Landlords written request therefor.

(c) Schedule. Landlord shall provide Tenant with a proposed schedule for the construction and installation of the Tenant
Improvements, a preliminary copy of which is attached hereto as Exhibit B-1, and shall notify Tenant of any material changes to said schedule. Tenant agrees to coordinate with Landlord regarding the installation of Tenants phone and
data wiring and any other trade related fixtures that will need to be installed in the Leased Premises prior to Substantial Completion of the Tenant Improvements. In addition, if and to the extent permitted by applicable laws, rules and ordinances,
Tenant shall have the right to enter the Leased Premises for twenty (20) days prior to the anticipated date for Substantial Completion of the Tenant Improvements (as such date may be modified from time to time) in order to install fixtures
(such as racking) and otherwise prepare the Leased Premises for occupancy (which right shall expressly exclude making any structural modifications). During any entry prior to the date of Substantial Completion of the Tenant Improvements
(i) Tenant shall comply with all terms and conditions of this Lease other than the obligation to pay rent, (ii) Tenant shall not interfere with Landlords completion of the Tenant Improvements, (iii) Tenant shall cause its
personnel and contractors to comply with the terms and conditions of Landlords rules of conduct, as attached hereto as Exhibit B-2 and incorporated herein by reference, and (iv) Tenant shall not begin operation of its business.
Tenant acknowledges that Tenant shall be responsible for obtaining all applicable permits and inspections relating to any such entry by Tenant.

(d) Change Orders. Tenant shall have the right to request changes to the Scope of Work or the Plans and Specifications at any time by way of written change order (each, a Change Order, and collectively,
Change Orders). Provided such Change Order is reasonably acceptable to Landlord, Landlord shall prepare and submit promptly to Tenant a memorandum setting forth the impact on cost and schedule resulting from said Change Order (the
Change Order Memorandum of Agreement). Tenant shall, within three (3) days following Tenants receipt of the Change Order Memorandum of Agreement, either (i) execute and return the Change Order Memorandum of
Agreement to Landlord, or (ii) retract its request for the Change Order. At Landlords option, Tenant shall pay to Landlord (or Landlords designee), within ten (10) days following Landlords request and prior to
Tenants occupancy of the Leased Premises, any increase in the cost to construct and install the Tenant Improvements resulting from the Change Order, as set forth in the Change Order Memorandum of Agreement. Landlord shall not be obligated to
commence any work set forth in a Change Order until such time as Tenant has delivered to Landlord the Change Order Memorandum of Agreement executed by Tenant and, if applicable, Tenant has paid Landlord in full for said Change Order.

(e) Substantial Completion. For purposes of this Lease Substantial Completion (or any grammatical variation thereof)
shall mean (A) completion of construction of the Tenant Improvements in accordance with applicable law and in substantial accordance with the Plans and Specifications, subject only to punchlist items to be identified by Landlord and Tenant in a
joint inspection of the Leased Premises prior to Tenants occupancy, the completion of which will not materially affect Tenants use and occupancy of the Leased Premises, and (B) Landlords receipt of all necessary governmental
approvals and inspections which are Landlords responsibility to obtain and which are necessary in order for Tenant to occupy the Leased Premises, subject to the following parenthetical (Tenant acknowledging, however, that even if Landlord has
Substantially Completed the Tenant Improvements, Landlord may not be able to obtain an occupancy permit for the Leased Premises because of the need for completion of all or a portion of improvements being installed in the Leased Premises directly by
Tenant). For purposes of this Lease, Tenant Delay shall mean any delay in the completion of the Tenant Improvements attributable to Tenant, including, without limitation, (A) Tenants failure to meet any time deadlines
specified herein, (B) Change Orders, (C) Tenants requirements for special work or materials, finishes or



---

installations other than Building standard and Landlord noting such to Tenant in writing, (D) the performance of any
other work in the Leased Premises by any person, firm or corporation employed by or on behalf of Tenant, or any failure to complete or delay in completion of such work, and (E) any other act or omission of Tenant.

(f) Commencement Date. Notwithstanding anything to the contrary contained in Section 2.01 above, if Substantial Completion of the
Tenant Improvements is delayed beyond the Target Commencement Date as a result of Tenant Delay, then, for purposes of determining the Commencement Date, Substantial Completion of the Tenant Improvements shall be deemed to have occurred on the date
that Substantial Completion of the Tenant Improvements would have occurred but for such Tenant Delay. Without limiting the foregoing, Landlord shall use commercially reasonable speed and diligence to Substantially Complete the Tenant Improvements on
or before the Target Commencement Date. Promptly following the Commencement Date, Tenant shall execute Landlords Letter of Understanding in substantially the form attached hereto as Exhibit C and made a part hereof, acknowledging
(x) the Commencement Date of this Lease, and (y) except for any punchlist items related to the Tenant Improvements, that Tenant has accepted the Leased Premises. If Tenant takes possession of and occupies the Leased Premises, Tenant shall
be deemed to have accepted the Leased Premises and that the condition of the Leased Premises and the Building was at the time satisfactory and in conformity with the provisions of this Lease in all respects, subject to any punchlist items related to
the Tenant Improvements.

Section 2.03. Surrender of the Leased Premises. Upon the expiration or earlier termination of
this Lease, Tenant shall immediately surrender the Leased Premises to Landlord in broom-clean condition, in good condition and repair, ordinary wear and tear and casualty loss and condemnation covered by Articles 9 and 10 excepted, and in
accordance with the surrender conditions listed on the Exhibit D attached hereto. Tenant shall also remove its personal property, trade fixtures, wiring and cabling (including above ceiling) installed by Tenant, to the extent required by law
or regulation or to the extent required by Landlord in its reasonable discretion, and any of Tenants alterations approved by Landlord and designated for such removal by Landlord at the time of Landlords approval or any other of
Tenants alterations not approved by Landlord which Landlord may require in its reasonable discretion be removed. Tenant shall promptly repair any damage caused by such removal, and restore the Leased Premises to the condition existing prior to
the installation of such items, ordinary wear and tear and casualty loss and condemnation covered by Articles 9 and 10 excepted. Unless otherwise agreed in writing by Landlord, at Landlords option, Tenant shall be required to remove any
unique Tenant Improvements installed as a result of Tenants specific use of the Leased Premises. If Tenant fails to do so, Landlord may restore the Leased Premises to such condition at Tenants expense, Landlord may cause all of said
property to be removed at Tenants expense, and Tenant hereby agrees to pay all the costs and expenses thereby reasonably incurred. Unless otherwise agreed in writing by Landlord, all Tenant property which is not removed within ten
(10) days following Landlords written demand therefor shall be conclusively deemed to have been abandoned by Tenant, and Landlord shall be entitled to dispose of such property at Tenants cost without thereby incurring any liability
to Tenant. Notwithstanding anything in this Lease to the contrary, Landlord agrees that Tenant shall not be required to remove any of the Tenant Improvements constructed by Landlord pursuant to Section 2.02 of this Lease unless otherwise
noted on the Plans and Specifications. The provisions of this Section 2.03 shall survive the expiration or other termination of this Lease.

Section 2.04. Holding Over. If Tenant retains possession of the Leased Premises after the expiration or earlier termination of this Lease, Tenant shall become a tenant from month to month at 150% of
the Monthly Rental Installment then in effect at the expiration or earlier termination of this Lease, and otherwise upon the terms, covenants and conditions herein specified, so far as applicable. Acceptance by Landlord of rent after such expiration
or earlier termination shall not result in a renewal of this Lease, and Tenant shall vacate and surrender the Leased Premises to Landlord upon Tenant being given thirty (30) days prior written notice from Landlord to vacate whether or not
said notice is given on the rent paying date. This Section 2.04 shall in no way constitute a consent by Landlord to any holding over by Tenant upon the expiration or earlier termination of this Lease, nor limit Landlords remedies
in such event.

ARTICLE 3 - RENT

Section 3.01. Base Rent. Tenant shall pay to Landlord the Minimum Annual Rent in the Monthly Rental Installments, in advance, without demand, and without abatement, deduction or offset,
beginning on the Commencement Date and on or before the first day of each and every calendar month thereafter during the Lease Term. The Monthly Rental Installment for partial calendar months shall be prorated. In addition to the Security Deposit
payable by Tenant under the terms of Section 1.01H and Article 4 hereof, upon delivery of this Lease Agreement to Landlord, Tenant shall deposit with Landlord, an amount equal to Eighty Two Thousand Five Hundred Thirty Five and
95/100 Dollars ($82,535.95), which amount is to be applied toward the first months Monthly Rental Installment and Additional Rent.



---

Section 3.02. Additional Rent.

(a) Any amount required to be paid by Tenant hereunder (in addition to Minimum Annual Rent) and any charges or expenses incurred by Landlord on behalf of
Tenant under the terms of this Lease shall be considered Additional Rent payable in the same manner and upon the same terms and conditions as the Minimum Annual Rent reserved hereunder except as set forth herein to the contrary.
Any failure on the part of Tenant to pay such Additional Rent when and as the same shall become due shall entitle Landlord to the remedies available to it for non-payment of Minimum Annual Rent.

(b) In addition to the Minimum Annual Rent Tenant shall pay to Landlord for each calendar year during the Lease Term, as Additional Rent, Tenants
Proportionate Share of all costs and expenses incurred by Landlord during the Lease Term for Real Estate Taxes (as hereinafter defined), Insurance Premiums (as hereinafter defined), and Operating Expenses (as hereinafter defined) for the Building
and common areas (collectivelyCommon Area Charges).

(c) For purposes of this Lease, Operating
Expenses shall mean all of Landlords expenses for operation, repair, replacement and maintenance to keep the Building and common areas in good order, condition and repair, including, but not limited to, management fees or
administrative fees; utilities; insurance deductibles (except as otherwise set forth hereinbelow); stormwater discharge fees; license, permit, inspection and other fees; fees and assessments imposed by any covenants or owners association;
access patrols; and maintenance, repair and replacement (except as otherwise set forth hereinbelow) of the driveways, parking areas (including snow removal), exterior lighting, landscaped areas, walkways, curbs, drainage strips, storm conveyance
systems, sewer lines, exterior walls, foundation, structural frame, roof and gutters. The cost of any Operating Expenses which are of a capital nature, unless such costs are incurred to decrease the Operating Expenses of the Building or the common
areas, and if included, such cost shall be amortized over the useful life of such improvement (in accordance with generally accepted accounting principles or GAAP), and only the amortized portion shall be included in Operating Expenses.
Notwithstanding anything to the contrary contained in this Lease, Operating Expenses do not include the following costs: (1) depreciation; (2) debt service under mortgages or ground rent under ground leases, costs of restoration to the
extent of net insurance proceeds received by Landlord with respect thereto: (3) Intentionally Omitted; (4) for costs and expenses incurred in connection with leasing space in the Building to Tenant, including, without limitation, marketing
costs, leasing commissions and the costs of any inducements provided to Tenant, including but not limited to tenant finish allowances, costs incurred for materials and labor in connection with the installation of tenant improvements, rent
allowances, lease takeover costs, payment of moving costs and other similar costs and expenses; (5) for legal expenses in connection with this Lease; (6) for overtime or other expenses of Landlord in curing defaults of Landlord or
performing work expressly provided in this Lease to be borne at Landlords expense; (7) for federal income taxes, inheritance, estate, gift, franchise, corporation, net profits or similar taxes assessed against or imposed on or measured by
the income of Landlord from the operation of the Building; (8) for fees for professional services including legal, architectural, engineering, accounting and appraisal that are not directly related to the management, operation, repair and
maintenance of the Building; (9) incurred by Landlord to the extent that Landlord receives reimbursement for such costs from any source other than Tenant (including, but not limited to, insurance); (10) for real estate commissions,
attorneys fees and other costs and expenses incurred in connection with negotiations with purchasers or potential purchasers of the Building; (11) for rentals and other related expenses incurred in leasing air conditioning systems,
elevators or other equipment or machinery ordinarily considered to be of a capital nature, if such machinery or equipment would constitute a capital expenditure if purchased by Landlord; (12) for advertising and promotional expenditures;
(13) for penalties or fines incurred by Landlord due to a violation by Landlord of any legal requirements; (14) for salary, benefits and commissions of Landlords officers, management supervisors and leasing agents; (15) for
expenses related to Landlords compliance with environmental and/or disabilities laws, except to the extent such compliance is required due to the acts of Tenant, Tenants agents, employees, contractors or invitees or such compliance is
required because of amendments, changes or additions to any such laws, which amendment(s), changes or additions became effective after the date this Lease is signed and are required due to Tenants particular use or operations in the Leased
Premises (16) necessitated by or resulting from the negligence of Landlord, its agents, officers, or employees or Landlords breach of its obligations under this Lease; (17) replacement costs for the foundation, exterior walls,
structural frame, and roof of the Building, or (18) insurance deductibles for claims arising out of the negligence or willful misconduct of Landlord, its employees, agents or contractors.

(d) For purposes of this Lease, Insurance Premiums shall include insurance premiums for insurance coverage on the Building or common
areas and shall include all fire and extended coverage



---

insurance on the Building and all liability insurance coverage on the common areas of the Building, and the grounds,
sidewalks, driveways and parking areas related thereto, together with such other insurance coverages, including, but not limited to, rent interruption insurance, as are from time to time obtained by Landlord.

(e) For purposes of this Lease, Real Estate Taxes shall include any form of real estate tax or assessment or service payments in lieu
thereof, and any license fee, commercial rental tax, improvement bond or other similar charge or tax (other than inheritance, personal income or estate taxes, or any penalties imposed as a result of the late payment of Real Estate Taxes by Landlord)
imposed upon the Building or common areas (or against Landlords business of leasing the Building) by any authority having the power to so charge or tax, together with costs and expenses of contesting the validity or amount of Real Estate Taxes
which at Landlords option may be calculated as if such contesting work had been performed on a contingent fee basis (whether charged by Landlords counsel or representative; provided, however, that said fees are reasonably comparable to
the fees charged for similar services by others not affiliated with Landlord, but in no event shall fees exceed thirty-three percent (33%) of the good faith estimated tax savings). Additionally, Tenant shall pay, prior to delinquency, all taxes
assessed against and levied upon trade fixtures, furnishings, equipment and all personal property of Tenant contained in the Leased Premises. Landlord shall pay all Real Estate Taxes imposed upon the Building or common areas.

Section 3.03. Payment of Additional Rent. Landlord shall estimate in good faith the total amount of Additional Rent to be paid by
Tenant during each calendar year of the Lease Term, pro-rated for any partial years. Landlords estimate of the amount of Additional Rent for the calendar year 2004 is $1.34 per rentable square foot of the Leased Premises. Tenant acknowledges
that said amount is only an estimate and agrees to reimburse Landlord for the actual amount of Additional Rent payable by Tenant under the Lease in accordance with this Section 3.03. Commencing on the Commencement Date, Tenant shall pay
to Landlord each month, at the same time the Monthly Rental Installment is due, an amount equal to one-twelfth (1/12) of the estimated Additional Rent for such year. Within one hundred twenty (120) days after the end of each calendar year,
Landlord shall submit to Tenant a reasonably itemized statement of the actual amount of Additional Rent for such calendar year and within thirty (30) days after receipt of such statement, Tenant shall pay any deficiency between the actual
amount owed and the estimates paid during such calendar year. In the event of overpayment, Landlord shall credit the amount of such overpayment toward the next installments of Minimum Rent.

Tenant, at its sole cost and expense, shall have the right (to be exercised by giving written notice to Landlord within thirty (30) days after
receipt of Landlords statement) to audit and/or inspect Landlords books and records pertaining only to items affecting Operating Expenses for such previous calendar year. Such audit and/or inspection must be conducted during
Landlords normal business hours (and only after Tenant gives Landlord fifteen (15) days prior written notice) and commenced and concluded by no later than ninety (90) days after Tenants receipt of Landlords statement; and
provided further that such audit and/or inspection does not unreasonably interfere with the conduct of Landlords business. Tenant shall deliver to Landlord a copy of the results of such audit within five (5) days of its receipt by Tenant.
If Landlord and Tenant agree that Landlords calculation of Tenants share of Operating Expenses for the inspected calendar year was incorrect, the parties shall enter into a written agreement confirming such error and then, and only then,
Tenant shall be entitled to a credit against future Minimum Annual Rent for said overpayment (or a refund of any overpayment if the Lease Term has expired) or Tenant shall pay to Landlord the amount of any underpayment, as the case may be. If the
results of the audit indicate errors showing an overpayment of Operating Expenses by Tenant of more than five percent (5%) of the annual Operating Expenses, then Landlord shall pay for the cost and expense of Tenants independent
professionals, if any, conducting such audit, not to exceed Three Thousand and No/100 Dollars ($3,000.00), or if the results of the audit indicate no errors or an error which equals or is less than five percent (5%), the audit shall be at the
expense of Tenant. If Landlord spends more than eight (8) hours to accommodate Tenants right to audit hereunder, Tenant shall also pay to Landlord as Additional Rent Two Hundred Dollars ($200.00) per hour for each hour that Tenants
audit takes of Landlords property managers or asset managers time, provided such audit discloses no error or an error which equals or is less than five percent (5%) of the annual Additional Rent amount. All of the information
obtained through Tenants inspection with respect to financial matters (including, without limitation, costs, expenses and income) and any other matters pertaining to Landlord, the Leased Premises, the Building and/or the Park as well as any
compromise, settlement or adjustment reached between Landlord and Tenant relative to the results of the inspection shall be held in strict confidence by Tenant and its officers, agents, and employees; and Tenant shall cause its independent
professionals and any of its officers, agents or employees to be similarly bound. The obligations of Tenant in the preceding sentence shall survive the expiration or earlier termination of the Lease. Tenant may conduct such review by its own staff
or consultants or may use a qualified independent certified public accountant designated by Tenant to aid Tenant in conducting the audit; provided that in no event shall Tenant use any contingent fee-based auditor or consultant.

Section 3.04. Late Charges. Tenant acknowledges that Landlord shall incur certain
additional unanticipated administrative and legal costs and expenses if Tenant fails to timely pay any payment required hereunder. Therefore, in addition to the other remedies available to Landlord hereunder or at law, if any payment required to be
paid by Tenant to Landlord hereunder shall become overdue by more than five (5) days, such unpaid amount shall bear interest from the due date thereof to the date of payment at the prime rate (as reported in the Wall Street Journal) of
interest (the Prime Rate) plus six percent (6%) per annum.

Section 3.05. Nature of Rent. Landlord and
Tenant agree that any base rent, percentage rent, if any, and all additional rent paid to Landlord under this Lease (collectively referred to in this Section 3.05 as Rent) shall qualify as rents from real
property within the meaning of Section 512(b)(3) of the Internal Revenue Code of 1986, as amended (the Code) and the U.S. Department of Treasury Regulations promulgated thereunder (the Regulations). In the
event that Landlord, in its sole discretion, determines that there is any risk that all or part of any Rent shall not qualify as rents from real property for the purposes of Section 512(b)(3) of the Code and the Regulations promulgated
thereunder, Tenant agrees (i) to cooperate with Landlord to restructure this Lease so as to cause all Rent to qualify as rents from real property, and (ii) to permit an assignment of this Lease, provided, however, that any adjustments
required pursuant to this paragraph shall be made so as to produce the equivalent Rent (in economic terms) payable prior to such adjustment.

ARTICLE 4 - SECURITY DEPOSIT

Tenant, upon execution of this Lease, shall deposit with Landlord the Security Deposit
as security for the performance by Tenant of all of Tenants obligations contained in this Lease. In the event of a default by Tenant Landlord may apply all or any part of the Security Deposit to cure all or any part of such default; provided,
however, that any such application by Landlord shall not be deemed to be an election of remedies by Landlord or viewed as liquidated damages. Tenant agrees to promptly, upon demand, deposit such additional sum with Landlord as may be required to
maintain the full amount of the Security Deposit. All sums held by Landlord pursuant to this Article 4 shall be without interest. At the end of the Lease Term, provided that there is then no uncured default, Landlord shall return the Security
Deposit to Tenant.

ARTICLE 5 - USE

(iii) comply with any protective covenants applicable to the Park which are in effect and as may hereafter be adopted and promulgated, and (iv) comply with and obey all reasonable directions of the Landlord, as well as any rules and

overload the floors of the Leased Premises. All damage to the floor structure or foundation of the Building due to improper positioning or storage of items or materials shall be repaired by Landlord at the sole expense of Tenant, who shall reimburse
Landlord immediately therefor upon demand. Tenant shall not use the Leased Premises, or allow the Leased Premises to be used, for any purpose or in any manner which would invalidate any policy of insurance now or hereafter carried on the Building or
increase the rate of premiums payable on any such insurance policy unless Tenant reimburses Landlord as Additional Rent for any increase in premiums charged. On or before the Commencement Date, Tenant shall take possession of, and, thereafter,
continuously occupy the Leased Premises during the term of this Lease, and operate thereon the normal business operations of Tenant.

repairs within a reasonable time after Landlord notifies Tenant in writing of the necessity of such repairs, provided, however, that any repairs made by Landlord shall be at Tenants expense, except as provided in Section 7.02
hereof and further provided that Landlord shall incur no liability to Tenant for such entry, nor shall such entry constitute an eviction of Tenant or a termination of this Lease, or entitle Tenant to any abatement of rent therefor.

ARTICLE 6 - UTILITIES AND SERVICES

Tenant shall obtain in its own name and pay directly to the appropriate supplier the cost of all utilities and services serving the Leased Premises. Landlord shall not be liable in damages or otherwise for any failure or interruption of any

preventive maintenance contract shall meet or exceed Landlords standard maintenance criteria, and shall provide for the inspection and maintenance of the heating, ventilating and air conditioning system on not less than a semi-annual basis. In
the event Tenant fails to maintain the Leased Premises as required herein or fails to commence repairs (reasonably requested by Landlord in writing) within thirty (30) days after such request, or fails diligently to proceed thereafter to
complete such repairs, Landlord shall have the right in order to preserve the Leased Premises or portion thereof, and/or the appearance thereof, to make such repairs or have a contractor make such repairs and charge Tenant for the cost thereof as
additional rent, together with interest at the rate of twelve percent (12%) per annum from the date of making such payments. Landlord shall provide Tenant with a key to the fire pump serving the Building and shall have direct access to such

the results of any such tests shall be promptly provided to Landlord. Tenant shall indemnify, defend and hold harmless Landlord, its agents, employees and contractors from and against any and all claims, demands, penalties, costs, liabilities,

arising in connection with Tenants access or use of the fire pump serving the Building, except to the extent caused by the negligence or willful misconduct of Landlord or its agents or contractors. Notwithstanding the foregoing, nothing

(a) Tenant shall not permit alterations in or to the Leased Premises unless and until the plans and the contractor have been approved by Landlord in
writing. As a condition of such approval, Landlord may require Tenant to remove the alterations and restore the Leased Premises upon termination of this Lease; otherwise, all such alterations shall at Landlords option become a part of the
realty and the property of Landlord, and shall not be removed by Tenant. Tenant shall ensure that all alterations shall be made in accordance with all applicable laws, regulations and building codes, in a good and workmanlike manner and of quality
equal to or better than the original construction of the Building and that its contractors comply with the terms and conditions of Landlords building standards (which Landlord agrees to furnish to Tenant upon request therefor). Upon completion
of the work, Tenant shall provide lien waivers from the subcontractors or a final affidavit of lien waiver from the general contractor, and such lien waiver shall be in a form acceptable to Landlord. No person shall be entitled to any lien derived
through or under Tenant for any labor or material furnished to the Leased Premises, and nothing in this Lease shall be construed to constitute a consent by Landlord to the creation of any lien. If any lien is filed against the Leased Premises for
work claimed to have been done for or material claimed to have been furnished to Tenant, Tenant shall cause such lien to be discharged of record within thirty (30) days after filing. Tenant shall indemnify Landlord from all costs, losses,
expenses and attorneys fees in connection with any construction or alteration done by or for Tenant and any related lien.

during the Lease Term or upon Tenants surrender of the Leased Premises, and Tenant may remove the Personal Property from the Building or the Leased Premises at any time at Tenants sole cost and expense. Upon the termination of the Lease,
Tenant shall remove its Personal Property, shall promptly repair any damage caused by the installation or removal of the Personal Property and shall restore the Leased Premises and the Building to the condition existing prior to the installation of

good faith efforts to notify Tenant within sixty (60) days after such damage as to the amount of time Landlord reasonably estimates it will take to restore the Building and/or Leased Premises and if the Lease is not terminated as hereinafter

11



---

(30) days written notice to the other party, terminate this Lease with respect to matters thereafter accruing.

for the Permitted Use, , Tenant may terminate this Lease by giving written notice to Landlord on or before the date that actual possession thereof is so taken. All damages awarded shall belong to Landlord; provided, however, that Tenant may make a

to a third party that is already a tenant in the Building or the Park). Subject to Section 11.02 below, any change in control of Tenant resulting from a merger, consolidation, stock transfer or asset sale shall be considered an
assignment or transfer that requires Landlords prior written consent. In the event of any assignment or subletting, Tenant shall remain primarily liable hereunder, and any extension, expansion, rights of first offer, rights of first refusal or
other options granted to Tenant under this Lease shall be rendered void and of no further force or effect. The acceptance of rent from any other person shall not be deemed to be a waiver of any of the provisions of this Lease or to be a consent to
the assignment of this Lease or the subletting of the Leased Premises. Any assignment or sublease consented to by Landlord shall not relieve Tenant (or its assignee) from obtaining Landlords consent to any subsequent assignment or sublease of
the Leased Premises. Without in any way limiting Landlords right to refuse to consent to any assignment or subletting of this Lease, Landlord shall be deemed to have reasonably withheld its consent to a proposed assignment or sublease of the
Leased Premises if in Landlords reasonable opinion (i) the Leased Premises are or may be in any way adversely affected; (ii) the business reputation of the proposed assignee or subtenant is unacceptable; (iii) the financial
worth of the proposed assignee or subtenant is insufficient to meet the obligations hereunder; or (iv) the prospective assignee or subtenant is a current tenant of the Park. In the event that Tenant sublets the Leased Premises or any part
thereof, or assigns this Lease, and at any time receives rent and/or other consideration which exceeds that which Tenant would at that time be obligated to pay to Landlord, Tenant shall pay to Landlord, as Additional Rent, fifty percent
(50%) of such excess in such rent as such rent is received by Tenant and fifty percent (50%) of any other consideration received by Tenant from such assignee or subtenant. Tenant agrees to pay Landlord Five Hundred and No/100 Dollars
($500.00) upon demand by Landlord, to reimburse Landlord for reasonable accounting and attorneys fees incurred in conjunction with the processing and documentation of any such requested assignment, subletting (requiring consent) or any other
hypothecation of this Lease or Tenants interest in and to the Leased Premises.

Section 11.02. Permitted Transfer.
Notwithstanding anything to the contrary contained in Section 11.01 above, Tenant shall have the right, without Landlords consent, but upon ten (10) days prior notice to Landlord, to (i) sublet all or part of the Leased
Premises to any related corporation or other entity which controls Tenant, is controlled by Tenant or is under common control with Tenant (Tenant Affiliate); (ii) assign all or any part of this Lease to any Tenant Affiliate or to a
successor entity into which or with which Tenant is merged or consolidated or which acquires substantially all of Tenants assets in property; or (iii) effectuate any public offering of Tenants stock on any stock exchange or in the
NASDAQ over the counter market, provided that in the event of a transfer pursuant to clause (ii), the net worth after any such transaction is not less than the net worth of Tenant as of the date hereof and provided further that such successor entity
assumes all of the obligations and liabilities of Tenant under this Lease (any such entity hereinafter referred to as a Permitted Transferee). For the purpose hereof control shall mean ownership of not less than fifty percent
(50%) of all voting stock or legal and equitable interest in such corporation or entity. Any such transfer shall not relieve Tenant of its obligations under this Lease.



---

ARTICLE 12 - TRANSFERS BY LANDLORD

Section 12.01. Sale of the Building. In the event of a sale or transfer of such interest (except a mortgage or other transfer as
security for a debt), the Landlord named herein, or in the case of a subsequent transfer, the transferor shall, after the date of such transfer, be automatically released from all personal liability for the performance or observance of
any term, condition, covenant or obligation required to be performed or observed by Landlord hereunder, and the transferee shall be deemed to have assumed all of such terms, conditions, covenants and obligations.

Section 12.02. Estoppel Certificate. Within ten (10) days following receipt of a written request from Landlord, Tenant shall
execute and deliver to Landlord, an estoppel certificate in such form as Landlord may reasonably request certifying (i) that this Lease is in full force and effect and unmodified or stating the nature of any modification, (ii) the date to
which rent has been paid, (iii) that there are not, to Tenants knowledge, any uncured defaults or specifying such defaults if any are claimed, and (iv) any other matters or state of facts reasonably required respecting the Lease.
Such estoppel may be relied upon by Landlord and by any purchaser or mortgagee of the Building.

Section 12.03.
Subordination. This Lease is and shall be expressly subject and subordinate at all times to the lien of any present or future mortgage or deed of trust encumbering fee title to the Leased Premises. If any such mortgage or deed of trust be
foreclosed, upon request of the mortgagee or beneficiary, as the case may be, Tenant will attorn to the purchaser at the foreclosure sale. The foregoing provisions are declared to be self-operative and no further instruments shall be required to
effect such subordination and/or attornment; provided, however, that subordination of this Lease to any present or future mortgage or trust deed shall be conditioned upon the mortgagee, beneficiary, or purchaser at foreclosure, as the case may be
agreeing that Tenants occupancy of the Leased Premises and other rights under this Lease shall not be disturbed by reason of the foreclosure of such mortgage or trust deed, as the case may be, so long as Tenant is not in default under this
Lease; and further provided that Tenant agrees upon request by any such mortgagee, beneficiary, or purchaser at foreclosure, as the case may be, to execute such non-disturbance, subordination and/or attornment instruments as may be reasonably
required by such person to confirm such non-disturbance subordination and/or attornment.

Landlord warrants that as of the date of this
Lease, there is no financing affecting the Building. If at any time after the date of this Lease, Landlord places financing on the Building, Landlord agrees that it shall use commercially reasonable efforts, upon written request by Tenant and at
Tenants sole expense, to provide Tenant with a commercially reasonable non-disturbance, subordination and attornment agreement in favor of Tenant from any ground lessors, mortgage holders or lien holders then in existence, in a form reasonably
satisfactory to Tenant and Tenants lender.

ARTICLE 13 - DEFAULT AND REMEDY

Section 13.01. Default. The occurrence of any of the following shall be a Default:

(a) Tenant fails to pay any Monthly Rental Installment or Additional Rent required herein when it is due, and such failure shall continue for a period of
five (5) days after written notice from Landlord to Tenant that such payment was due; provided, however, that Landlord shall not be obligated to provide written notice of such failure more than two (2) times in any consecutive 12-month
period, and the failure of Tenant to pay any third or subsequent installment of Base Rent or any other payment required herein within five (5) days of when due in any consecutive 12-month period shall constitute an Event of Default by Tenant
under this Lease without the requirement of notice or opportunity to cure; provided, however, that any such notice shall be in lieu of, and not in addition to, any notice required under applicable law.

(b) Tenant fails to perform or observe any other term, condition, covenant or obligation required under this Lease for a period of thirty (30) days
after notice thereof from Landlord; provided, however, that if the nature of Tenants default is such that more than thirty (30) days are reasonably required to cure, then such default shall be deemed to have been cured if Tenant commences

(c) Tenant shall assign or sublet all or a portion of the Leased Premises in contravention of the provisions of Article 11 of this Lease.

Section 13.02. Remedies. Upon the occurrence of any Default, Landlord shall have the following rights and remedies, in addition to
those allowed by law or in equity, any one or more of which may be exercised without further notice to Tenant:

(a) Landlord may terminate
this Lease as of the date of such Default, and thereafter (i) neither Tenant nor any person claiming under or through Tenant shall be entitled to possession of the Leased Premises, and Tenant shall immediately surrender the Leased Premises to
Landlord; and (ii) Landlord may re-enter the Leased Premises and dispossess Tenant and any other occupants of the Leased Premises by any lawful means and may remove their effects, without prejudice to any other remedy which Landlord may have.
Upon the termination of this Lease, Landlord may declare the present value (discounted at the Prime Rate) of all rent which would have been due under this Lease for the balance of the Lease Term in excess of the present value of any net amounts
which Tenant establishes Landlord can reasonably expect to recover by reletting the Leased Premises for such period, taking into consideration the availability of acceptable tenants and other market conditions affecting leasing to be immediately due
and payable, whereupon Tenant shall be obligated to pay the same to Landlord, together with all loss or damage which Landlord may sustain by reason of Tenants Default (Default Damages), which shall include without limitation
expenses of preparing the Leased Premises for re-letting, demolition, repairs, tenant finish improvements, brokers commissions and attorneys fees, it being expressly understood and agreed that the liabilities and remedies specified in
this subsection (a) shall survive the termination of this Lease. In addition to the Default Damages, Landlord shall be entitled to any amounts or damages payable by Tenant to Landlord and accruing prior to the date of termination, which for all
purposes shall include, but not be limited to, accrued rent and interest thereon, late charges and interest thereon the unamortized cost of Tenants improvements, brokers fees and commissions, attorneys fees, any moving allowances
and any other costs incurred by Landlord in connection with making or executing this Lease. Nothing contained in this Lease shall limit or prejudice the right of Landlord to prove for and obtain in proceedings for bankruptcy or insolvency by reason
of the termination of this Lease, an amount equal to the maximum allowed by any statute or rule of law in effect at the time when, and governing the proceedings in which, the damages are to be proved, whether the amount be greater, equal to, or less
than the amount of the loss or damages referred to above.

(b) Landlord may, without terminating this Lease, terminate Tenants right
to possession of the Leased Premises as of the date of Tenants Default, and re-enter the Leased Premises and thereafter (i) neither Tenant nor any person claiming under or through Tenant shall be entitled to possession of the Leased
Premises, and Tenant shall immediately surrender the Leased Premises to Landlord; and (ii) Landlord may re-enter the Leased Premises and dispossess Tenant and any other occupants of the Leased Premises by any lawful means and may remove their
effects, without prejudice to any other remedy which Landlord may have. Thereafter, Landlord may, but shall not be obligated to, re-let all or any part of the Leased Premises as the agent of Tenant for a term different from that which would
otherwise have constituted the balance of the Lease Term and for rent and on terms and conditions different from those contained herein, whereupon Tenant shall be obligated to pay to Landlord as liquidated damages the difference between the rent
provided for herein and that provided for in any lease covering a subsequent re-letting of the Leased Premises, for the period that would otherwise have constituted the balance of the Lease Term, together with all Default Damages. Neither the filing
of a dispossessory proceeding nor an eviction of personalty in the Leased Premises shall be deemed to terminate the Lease.

(c) Landlord
may, without judicial process enter upon the Leased Premises, by force if necessary, without having any civil or criminal liability therefor (including specifically any liability or duty under Section 93.002 of the Texas Property Code which is
superseded by this Paragraph 13.02), 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 effecting compliance with Tenants
obligations under this Lease plus an administrative fee equal to ten percent (10%) of the amount of such reimbursement. Tenant further agrees that Landlord shall not be liable for any damages resulting to Tenant from such action, whether caused
by the negligence of Landlord or otherwise.

(d) Any repossession of or re-entering on the Leased Premises by Landlord under this Article
shall be without liability or responsibility for damages to Tenant. No repossession of or re-entering upon the Leased Premises or any part thereof pursuant to this Lease or otherwise and no reletting of the Leased Premises or any part thereof
pursuant to this Lease shall relieve Tenant or any guarantor of its liabilities and obligations hereunder, all of which shall survive such repossession or re-entering. In the event of any such repossession of or re-entering upon the Leased Premises
or any part thereof by reason of the occurrence of an event of Default, Tenant will continue to pay to Landlord Rent required to be paid by Tenant.



---

(e) No right or remedy herein conferred upon or reserved to Landlord is intended to be exclusive of any
other right or remedy, and each and every right and remedy shall be cumulative and in addition to any other right or remedy given hereunder or now or hereafter existing at law or in equity or by statute. In addition to the other remedies provided in
this Lease, Landlord shall be entitled, to the extent permitted by applicable law, to injunctive relief in case of the violation, or attempted or threatened violation, of any of the covenants, agreements, conditions or provisions of this Lease, or
to a decree compelling performance of any of the covenants, agreements, conditions or provisions of this Lease, or to any other remedy allowed to Landlord at law or in equity.

(f) If Landlord repossesses the Leased Premises pursuant to the authority herein granted or provided at law or in equity, then Landlord shall have the
right to remove and store all of the furniture, fixtures and equipment at the Leased Premises, including that which is owned by or leased to Tenant at all times prior to any foreclosure thereon by Landlord or repossession thereof by any Landlord
thereof or third party having a superior lien thereon. Landlord also shall have the right to relinquish possession of all or any portion of such furniture, fixtures, equipment and other property to any person (a Claimant) who
presents to Landlord a copy of any instrument represented by Claimant to have been executed by Tenant (or any predecessor of Tenant) granting Claimant the right under various circumstances to take possession of such furniture, fixtures, equipment or
other property, without the necessity on the part of Landlord to inquire into the authenticity or legality of said instrument. The rights of Landlord herein stated shall be in addition to any and all other rights that Landlord has or may hereafter
have at law or in equity; and Tenant stipulates and agrees that the rights herein granted Landlord are commercially reasonable.

(g) No
agreement to accept a surrender of the Leased Premises and no act or omission by Landlord or Landlords agent during the term shall constitute an acceptance or surrender of the Leased Premises unless made in writing and signed by Landlord. No
reentry or taking possession of the Leased Premises by Landlord shall constitute an election by Landlord to terminate this Lease unless a written notice of such intention is given to Tenant.

(h) TENANT HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED UNDER APPLICABLE LAW, ANY DUTY ON THE PART OF LANDLORD TO RELET THE LEASED PREMISES OR
OTHERWISE MITIGATE ANY LOSS OR DAMAGE ARISING FROM ANY DEFAULT OF TENANT.

Section 13.03. Landlords Default and
Tenants Remedies. Landlord shall be in default if it fails to perform any term, condition, covenant or obligation required under this Lease for a period of thirty (30) days after written notice thereof from Tenant to Landlord;
provided, however, that if the term, condition, covenant or obligation to be performed by Landlord is such that it cannot reasonably be performed within thirty (30) days, such default shall be deemed to have been cured if Landlord commences
such performance within said thirty-day period and thereafter diligently undertakes to complete the same within a reasonable time. Upon the occurrence of any such default, Tenant may sue for injunctive relief or to recover damages for any loss
directly resulting from the breach, but Tenant shall not be entitled to terminate this Lease or withhold, offset or abate any sums due hereunder.

As to Landlords maintenance and repair obligations hereunder, if Landlord has not cured or commenced to cure a maintenance or repair default set forth in said notice from Tenant within said 30-day period, Tenant may undertake all
reasonable action to cure Landlords failure of performance. In the event of an emergency where the safety of Tenants employees is threatened or emergency measures are necessary to preserve Tenants property or the Leased Premises,
Tenant shall be entitled to make any repairs which are necessary after having first given Landlord reasonable notice under the circumstances of the necessity for such repair.If Tenant elects to cure said default, Tenant shall, prior to
commencement of said work, provide to Landlord a specific description of the work to be performed by Tenant and the name of Tenants contractor. Any materials used shall be of equal or better quality than currently exists in the Building and
Tenants contractor shall be adequately insured and of good reputation. Landlord agrees to reimburse Tenant on demand for all reasonable, third party out-of-pocket expenses incurred by Tenant in connection therewith, provided that Tenant
delivers to Landlord adequate bills or other supporting evidence substantiating said cost. If Landlord does not reimburse Tenant within thirty (30) days of receipt of an invoice therefor, Tenant may sue for injunctive relief but Tenant shall
not be entitled to terminate this Lease or withhold, offset or abate any sums due hereunder except pursuant to an order from a court of competent jurisdiction; provided however, that pending the outcome of such suit, Tenant may tender to the court
rather than to Landlord rent payments thereafter coming due under this Lease up to the amount claimed by Tenant to be owed to Tenant from Landlord.



---

Section 13.04. Limitation of Landlords Liability. If Landlord shall fail to
perform any term, condition, covenant or obligation required to be performed by it under this Lease and if Tenant shall, as a consequence thereof, recover a money judgment against Landlord, Tenant agrees that it shall look solely to Landlords
right, title and interest in and to the Building for the collection of such judgment; and Tenant further agrees that no other assets of Landlord shall be subject to levy, execution or other process for the satisfaction of Tenants judgment.

Section 13.05. Nonwaiver of Defaults. Neither partys failure or delay in exercising any of its rights or remedies
or other provisions of this Lease shall constitute a waiver thereof or affect its right thereafter to exercise or enforce such right or remedy or other provision. No waiver of any default shall be deemed to be a waiver of any other default.
Landlords receipt of less than the full rent due shall not be construed to be other than a payment on account of rent then due, nor shall any statement on Tenants check or any letter accompanying Tenants check be deemed an accord
and satisfaction. No act or omission by Landlord or its employees or agents during the Lease Term shall be deemed an acceptance of a surrender of the Leased Premises, and no agreement to accept such a surrender shall be valid unless in writing and
signed by Landlord.

Section 13.06. Attorneys Fees. If either party defaults in the performance or observance of
any of the terms, conditions, covenants or obligations contained in this Lease and the non-defaulting party obtains a judgment against the defaulting party, then the defaulting party agrees to reimburse the non-defaulting party for reasonable
attorneys fees incurred in connection therewith.

Section 16.19. Contingency. Landlord and Tenant acknowledge that as of the date of
this Lease, Trillium Industries, Inc. (Trillium) is currently occupying a portion of the Leased Premises consisting of approximately 114,105 square feet (the Trillium Premises) pursuant to that certain Lease
Agreement dated February 29, 2000 between Landlord and Trillium. Landlord hereby represents that as of the date of this Lease, Landlord and Trillium have entered into a termination agreement covering the Trillium Premises, pursuant to which
Trillium is required to vacate all portions of the Trillium Premises except for the office area consisting of approximately 12,000 square feet (the Initial Surrender Space) on December 28, 2003 (the First Surrender
Date) and the remaining portion of the Trillium Premises (the Office Space) on December 28, 2003 (the Second Surrender Date).

accordance with the terms of this Lease. Upon delivery of Landlords Notice to Tenant in accordance with the terms of this Lease, Tenants right to terminate as set forth herein shall be deemed to be of no further force and effect.

Term, (ii) the creditworthiness of Tenant is then acceptable to Landlord, and (iii) Tenant originally named herein or a Tenant Affiliate or Permitted Transferee remains in possession of the Leased Premises, and (iii) any combination
of Tenant, a Tenant Affiliate or Permitted Transferee has been continuously operating in the entire Leased Premises for the term immediately preceding the Extension Term (defined below), Tenant shall have the option to extend the Term for one

applicable to the Leased Premises during the initial term of the Lease shall not apply to the Extension Term, and (ii) the Minimum Annual Rent for the Extension Term shall be adjusted as set forth hereinbelow (the Rent
Adjustment).Tenant shall exercise such option by delivering to Landlord, no later than Two Hundred Seventy (270) days prior to the expiration of the Lease Term, written notice of Tenants desire to extend the Lease Term
(Tenants Notice). Unless Landlord otherwise agrees in writing, Tenants failure to timely exercise such option shall waive it. Landlord shall notify Tenant of the amount of the Rent Adjustment no later than thirty
(30) days after receipt of Tenants Notice. Tenant shall have thirty (30) days following its receipt of Landlords notice to notify Landlord in writing that Tenant objects to the Rent Adjustment and therefore that Tenant retracts
