any alterations, modifications, improvements, additions, or installations if such action results or would result in a labor dispute or otherwise would materially interfere with Lessor's operation of
the Office Complex. Lessor, by written notice to Lessee given at or

38

---

prior to termination of this Lease, may require Lessee to remove any improvements, additions or installation installed by Lessee in the Premises at Lessee's sole cost and expense, and repair or
restore any damage caused by the installation and removal of such improvements, additions, or installations; provided, however, the only improvements, additions or installations which Lessee shall
remove shall be those specified in such notice. With respect to approval rights granted to Lessor in this Article 8 for other than Major Alterations, Lessor's approval shall be deemed given
following the expiration of thirty (30) days after Lessee delivers to Lessor in writing plans and specifications for the item or items for which Lessor's approval is sought if Lessor has not
sooner disapproved same.

Section 8.2 Freedom From Liens.Lessee shall keep the Premises and the Office Complex free from any liens arising out
of any work performed, material furnished or obligations incurred by Lessee, and shall indemnify, protect, defend and hold Lessor harmless from any liens and encumbrances arising out of any work
performed or material furnished by or at the direction of Lessee. In the event that Lessee shall not, within thirty (30) days following the imposition of any such lien, cause such lien to be
released of record by payment or posting of a proper bond, Lessor shall have, in addition to all other remedies provided herein and by law, the right, but not the obligation, to cause the same to be
released by such means as it shall deem proper, including payment of and/or defense against the claim giving rise to such lien. All such sums paid by Lessor and all expenses incurred by it in
connection therewith, including attorneys' fees and costs, shall be payable as Additional Rent to Lessor by Lessee on demand with interest at the maximum rate per annum then permitted by law accruing
from the date which is five (5) days following Lessee's receipt of written notice that same has been paid or incurred by Lessor until reimbursed to Lessor by Lessee.

Section 8.3 Alterations a Part of the Premises.Any permanent additions to, or alterations of, the Premises, except as
specified in Lessor's notice to Lessee, shall become at once a part of the Premises and belong to Lessor without compensation to Lessee. The foregoing shall not be applicable to removable equipment,
trade fixtures, shelving, filing, computers, telecommunications equipment, cabling, secretarial stations, cubicles, carrels, movable partitions, kitchen equipment, attached modular furniture or
Lessee's personal property, which Lessee shall remove, and upon removal shall repair any damage to the Premises due to such removal.

ARTICLE 9  REPAIRS

Section 9.1 Lessee's Repair Obligations.Lessee shall, during the term of this Lease, at Lessee's expense, keep the
Premises and Office Complex (including, without limitation, all exterior facilities, parking facilities and common areas) in as good order, condition and repair as they were at the time Lessee took
possession of the same, reasonable wear and tear excepted and repairs required of Lessor pursuant to Section 9.4 hereof also excepted. Lessee shall keep the Premises and Office Complex
(including, without limitation, all exterior facilities, parking facilities and common areas) in a neat and sanitary condition and shall not commit any nuisance or waste on the Premises or in, on, or
about the office complex, throw improper substances in the plumbing facilities, or waste any of the utilities furnished by the Lessor. All uninsured damage or injury to the Premises, or to the Office
Complex caused by Lessee moving furniture, fixtures, equipment, or other devices in or out of the Premises or Office Complex or by installation or removal of furniture, fixtures, equipment, devices or
other property of Lessee, its agents, contractors, servants or employees, due to carelessness, omission, neglect, improper conduct, or other cause of Lessee, its servants, employees, agents, visitors,
or licensees, shall be repaired, restored and replaced promptly by Lessee at its sole cost and expense. All repairs, restorations and replacements shall be in quality and class equal to the original
work and shall comply with all requirements of the Lease.

39

---

Section 9.2 Lessor's Inspection.Lessor or its employees, or agents, shall have the right to enter the Premises
following at least twelve (12) hours prior notice thereof to Lessee (except that no prior notice to Lessee shall be required in the event of an emergency) at any reasonable time or times for
the purpose of inspection, cleaning, repairs, altering, or improving the same but nothing contained herein shall be construed as imposing any obligation on Lessor to make any repairs, alterations or
improvements which are the obligation of Lessee; provided, however, that Lessor shall not unreasonably interfere with Lessee's use and occupancy of the Premises.

Section 9.3 Joint Inspection Upon Vacation.Lessee shall give written notice to Lessor at least thirty
(30) days prior to vacating the Premises for the express purpose of arranging a meeting with Lessor for a joint inspection of the Premises. In the event of Lessee's failure to give such notice
and arrange such joint inspection, Lessor's inspection at or after Lessee's vacation of the Premises shall be conclusively deemed correct for purposes of determining Lessee's responsibility for
repairs and restoration hereunder.

Section 9.4 Lessor's Repair Obligations.Lessor shall, during the term of this Lease, at Lessor's expense, keep the
roof and structural components of the Office Complex in first class condition and repair and
in a neat, clean and healthful manner, excluding any damage to the roof or structural components, caused by Lessee, its agents, employees or invitees, which shall be repaired by Lessee, at its sole
cost. All repairs, restorations and replacements shall be performed in good and workmanlike manner and in quality and class equal to the original work and shall comply with all requirements of the
Lease. If Lessor fails to perform any of Lessor's obligations under this paragraph, and if such failure continues for thirty (30) days after written notice thereof is delivered to Lessor
(provided, that, in the event of an emergency or situation where damage to person or property is at risk, no notice shall be required), Lessee may perform such obligation, in which event, Lessor shall
pay to Lessee the reasonable cost incurred by Lessee in performing such obligation within thirty (30) days after demand therefor (with accompanying paid invoices), failing which Lessee shall be
entitled to offset such sums against the Rent becoming due under this Lease, provided any offset shall not exceed twenty percent (20%) of monthly Base Rent until such offset has been fully made. In
the event the expenditure cannot be fully recouped from the next monthly payment of Base Rent as a result of such limitation, Lessee shall be entitled to recover interest with respect to each
subsequent monthly offset from the date of the expenditure to the date of offset at a per annum rate equal to the bank prime rate publicized in theWall Street
Journal, as the same may change from time to time.

Section 9.5 Lessee's Waiver of Claims Against Lessor.Lessor shall not be required to furnish any services or
facilities or to make any repairs or alterations in, about or to the Premises or Office Complex, except as provided inSection 9.4hereof. Tenant
hereby assumes the full and sole responsibility for the condition, operation, repair, replacement, maintenance and management of the Premises and Office Complex, and Tenant hereby waives any rights
created by any law now or hereafter in force to make repairs to the Premises or Office Complex at Landlord's expense, except as provided in Section 9.4hereof.

ARTICLE 10  ASSIGNMENT AND SUBLETTING

Section 10.1 Procedure for Obtaining Lessor's Consent.Lessee shall not, without the prior written consent of Lessor,
(a) transfer, pledge, mortgage or assign this Lease or any interest hereunder; (b) permit any assignment of this Lease by voluntary act, operation of law or otherwise other than through
merger, consolidation or change of form of business organization; or (c) permit the use of the Premises by any parties other than Lessee, its agents and employees; provided, Lessee may sublease
portions of the Premises without the prior written consent of Lessor (but with prompt written notice given to Lessor and a copy of such sublease) so long as Lessee is not in default of this Lease, the

40

---

sublease when combined with all other subleases does not exceed 98,957 square feet, the sublease is made expressly subject to the terms and conditions of this Lease, the use of the subleased premises
is consistent with Section 4.3 hereof and the sublease is approved by Lessor's mortgagee if the sublease is for more than 24,000 square feet of space or if the sublease when combined with other
subleases exceeds 98,957 square feet. Lessee shall seek any required written consent of Lessor or its mortgagee by a written request therefor, setting forth such information as Lessor or its mortgagee
may deem reasonably necessary. Lessee shall, by notice in writing, advise Lessor and its mortgagee of its intention
from, on and after a stated date (which shall not be less than thirty [30] days after date of Lessee's notice), to assign this Lease or to sublet any part of the Premises which
requires the consent of Lessor or its mortgagee for the balance or any part of the term. Lessee's notice shall include all of the terms of the proposed assignment or sublease and shall state the
consideration therefor. With respect to a proposed sublease, Lessee's notice shall state the name and address of the proposed subtenant and a true and complete copy of the proposed sublease together
with current financial statements on the proposed assignee or sublease shall be delivered to Lessor and its mortgagee with Lessee's notice. If Lessor's mortgagee does not timely disapprove of the
proposed sublease as provided in the Subordination, Attornment and Non-Disturbance Agreement (as amended, the "SNDA") between Lessor, Lessee and Lessor's mortgagee then such proposed
sublease shall be deemed approved by Lessor's mortgagee. In the event of any proposed assignment by Lessee, or in the event of any proposed sublease which requires Lessor's consent, Lessor shall have
the right to be exercised by giving written notice to Lessee within thirty (30) days after receipt of Lessee's notice, to recapture the space described in Lessee's notice and such recapture
notice shall, if given, cancel and terminate this Lease with respect to the space therein described as of the date stated in Lessee's notice. If Lessee's notice shall cover all of the Premises, and
Lessor shall have exercised its foregoing recapture right, the term of this Lease shall expire and end on the date stated in Lessee's notice as fully and completely as if that date had been herein
definitely fixed for the expiration of the term. If, however this Lease be canceled with respect to less than the entire Premises, the Base Rent and Additional Rent shall be equitably adjusted by
Lessor with due consideration of the size, location, type and quality of the portion of the Premises so remaining after the "recapture" and such rent shall be reduced accordingly from and after the
termination date for said portion, and this Lease as so amended shall continue thereafter in full force and effect. The rent adjustments provided for herein shall be evidenced by an amendment to Lease
executed by Lessor and Lessee. If this Lease shall be terminated in the manner aforesaid, either as to the entire Premises or only a portion thereof, to such extent the term of this Lease shall end
upon the appropriate effective date of the proposed sublease or assignment as if that date had been originally fixed in this Lease for such expiration, and in the event of a termination affecting less
than the entire Premises, Lessee shall comply with Article 13 ("Surrender of Premises") of this Lease with respect to all or any portion of the Premises affected thereby. Notwithstanding
anything to the contrary in thisArticle 10, any request of Lessee to assign this Lease or any interest hereunder is subject to the approval of
Lessor and Lessor's mortgagee, and the method of submission for approval of a sublease as provided herein and the method of approval or disapproval thereof as provided herein and/or in the SNDA is not
applicable to any request for approval of any assignment of this Lease or any interest hereunder.

Section 10.2 Discharge of Commission.Lessee shall, at its sole cost and expense, discharge in full (a) any
outstanding commission obligation on the part of Lessor with respect to this Lease in the event that all or any portion of this Lease is recaptured pursuant to this Article 10, and (b) any
commission which may be due and owing as a result of any proposed assignment or subletting, whether or not the
subject portion of the Premises is "recaptured" pursuant thereto and rented by Lessor to the proposed tenant or any other tenant.

Section 10.3 Right to Recapture Not Exercised.If Lessor, upon receiving Lessee's notice with respect to any such
space, shall not exercise its right to recapture as aforesaid, Lessor will not

41

---

unreasonably withhold its consent to Lessee's assignment of the Lease or subletting such space to the party identified in Lessee's notice.

Section 10.4 Lessee's Changes Deemed an Assignment.For purposes of the foregoing, any change in the partners of
Lessee, if Lessee is a partnership which results in a transfer of at least fifty percent (50%) or more of the interests in the partnership, or, if Lessee is a corporation, any transfer of at least
fifty percent (50%) of the shares of stock of Lessee by sale, assignment, operation of law or otherwise, shall be deemed to be an assignment within the meaning of this Article 10; provided,
however, that the sale of stock in a public offering for an aggregate price of at least Twenty Million Dollars ($20,000,000.00) shall not be deemed to be an assignment within the meaning of this Article 10.

Section 10.5 Continuing Lessee Liability.Any subletting or assignment hereunder shall not release or discharge Lessee
of or from any liability, whether past, present or future, under this Lease, and Lessee shall continue fully liable thereunder. The subtenant or subtenants or assignee shall agree in a form
satisfactory to Lessor to comply with and be bound by all of the terms, covenants, conditions, provisions and agreements of this Lease to the extent of the space sublet or assigned, and Lessee shall
deliver to Lessor promptly after execution an executed copy of each such sublease or assignment and an agreement of compliance by each such subtenant or assignee. Consent by Lessor to any assignment
of this Lease or to any subletting of the Premises shall not be a waiver of Lessor's rights under this Article 10 as to any subsequent assignment or subletting.

Section 10.6 Void Transfers.Any sale, assignment, mortgage, transfer, or subletting of this Lease which is not in
compliance with the provisions of this Article 10 shall be of no effect and void. Lessor's right to assign its interest in this Lease shall remain unqualified. Lessor may make a reasonable
charge to Lessee for any reasonable attorneys' fees or expenses incident to a review of any documentation related to any proposed assignment or subletting by Lessee which requires the written consent
of Lessor, not to exceed $5,000.00 per request. Notwithstanding anything contained herein to the contrary, Lessee shall be entitled, without otherwise complying with the provisions of this
Article 10, to assign this Lease or sublet the Premises to any parent, affiliate or subsidiary of Lessee, without first obtaining Lessor's consent; provided, Lessee shall remain fully liable
for the obligations of this Lease, and the assignee or sublessee shall assume all obligations of Lessee hereunder.

Section 10.7 Prohibited Transferees.Notwithstanding anything to the contrary in this Lease, Lessee shall not assign
its rights under this Lease (but may sublet a part of the Premises as set forth inSection 10.1above) to a person, firm or corporation which is
(or, immediately prior to such subletting or assignment, was) a tenant or occupant of the building located at 7701 Stemmons Freeway, Dallas, Texas.

Section 10.8 Criteria for Withholding Consent.The consent of Lessor to a transfer may not be unreasonably withheld,
conditioned or delayed, provided that should Lessor withhold its consent for any of the following reasons, which list is not exclusive, such withholding shall be deemed to be reasonable:



42

---



Lessee
agrees that its personal business skills and philosophy were an important inducement to Lessor for entering into this Lease and that Lessor may reasonably object to the transfer
of the Premises to another whose proposed use, while permitted by this Lease, would involve a different, quality, manner or type of business skills than that of Lessee.

the Premises untenantable, and the Premises can reasonably be expected to be made tenantable within two hundred forty (240) days from the date of such event, then Lessor, to the extent of
insurance proceeds available to Lessor, shall repair and restore the Premises and the Office Complex to as near their condition prior to the fire or other casualty as is reasonably possible within
such two hundred forty (240) day period (subject to delays for causes beyond Lessor's reasonable control) and notify Lessee that it will be doing so, such notice to be mailed within thirty
(30) days from the date of such damage or destruction, and this Lease shall remain in full force and effect, but the Rent for the period during which the Premises are untenantable shall be
abated pro rata (based upon the portion of the Premises which is untenantable). Notwithstanding anything to the contrary contained herein, in the event that no insurance proceeds are available, or
insufficient insurance proceeds are available to repair and restore the Premises, Lessee shall be responsible for the costs to repair and restore the Premises to the extent not covered by insurance.
If Lessor is required to repair the Office Complex and/or the Premises as aforesaid, said work shall be undertaken and prosecuted with all due diligence and speed, and shall be completed within two
hundred forty (240) days following the date of such fire or other casualty (subject to force majeure) failing which, Lessee shall be entitled to terminate this Lease in the event that such
repairs are not completed within sixty (60) days after written notice from Lessee that Lessee desires to terminate this Lease because such repairs have not been completed within such two
hundred forty (240) day period.

Section 11.2 Not Tenantable Within 240 Days.If fire or other casualty shall render the whole or any material part of
the Premises untenantable and the Premises cannot reasonably be expected to be made tenantable within two hundred forty (240) days from the date of such event, then either party, by notice in
writing to the other mailed within thirty (30) days from the date of such damage or destruction, may terminate this Lease effective upon the date of the damage or destruction or a date within
thirty (30) days from the date of such notice.

Section 11.3 Office Complex Substantially Damaged.In the event that more than fifty percent (50%) of the value of the
Office Complex is damaged or destroyed by fire or other casualty, and irrespective of whether damage or destruction can be made tenantable within two hundred forty (240) days thereafter, then
at Lessor's or Lessee's option, by written notice to the other, mailed within forty-five (45) days from
the date of such damage or destruction, either party may terminate this Lease effective upon the date of the damage or destruction or a date ninety (90) days after such notice.

Section 11.4 Deductible Payments.If the Premises or the Office Complex is damaged, and such damage is of the type
insured against under the fire and special form property damage insurance maintained hereunder, and if this Lease is not terminated as herein provided, the cost of repairing said damage up to the
amount of the deductible under said insurance policy shall be paid by Lessee within thirty (30) days after written notice to Lessee.

Section 11.5 Lessor's Repair Obligations.If fire or other casualty shall render the whole or any material part of the
Premises untenantable and the Premises cannot reasonably be expected to be made tenantable within two hundred forty (240) days from the date of such event and neither party hereto terminates
this Lease pursuant to its rights herein or in the event that more than fifty percent (50%) of the value of the Office Complex is damaged or destroyed by fire or other casualty, and neither party
terminates this Lease pursuant to its option granted herein, or in the event that fifty percent (50%) or less of the value of the Office Complex is damaged or destroyed by fire or other casualty and
neither the whole nor any material portion of the Premises is rendered untenantable, then Lessor, to the extent of insurance proceeds available to Lessor, shall repair and restore the Premises and the
Office Complex to as near their condition prior to the fire or other casualty as is reasonably possible with all due

44

---

diligence and speed (subject to delays for causes beyond Lessor's reasonable control) and shall be completed within two hundred forty (240) days following the date of such fire or other
casualty (subject to force majeure) failing which, Lessee shall be entitled to terminate this Lease in the event that such repairs are not completed within sixty (60) days after written notice
from Lessee that Lessee desires to terminate this Lease because such repairs have not been completed within such 240 day period. Notwithstanding anything to the contrary contained herein, in
the event that no insurance proceeds are available, or insufficient insurance proceeds are available to repair and restore the Premises, Lessee shall be responsible for the costs to repair and restore
the Premises to the extent not covered by insurance. Rent for the period during which the Premises are untenantable shall be abated pro rata (based upon the portion of the Premises which is
untenantable). In no event shall Lessor be obligated to repair or restore any special equipment or improvements installed by Lessee at Lessee's expense.

Section 11.6 Rent Apportionment.In the event of a termination of this Lease pursuant to this Article 11, Rent
shall be apportioned on a per diem basis and paid to the date of the fire or other casualty.

Section 12.1 Lessee's Termination.If the whole of or any substantial part of the Premises is taken by any public
authority under the power of eminent domain, or taken in any manner for any public or quasi-public use, so as to render (in Lessee's reasonable judgment) the remaining portion of the Premises
unsuitable for the purposes intended hereunder, then the term of this Lease shall cease as of the day possession shall be taken by such public authority and Lessor shall make a pro rata refund of any
prepaid rent. All damages awarded for such taking under the power of eminent domain or any like proceedings shall belong to and be the property of Lessor, Lessee hereby assigning to Lessor its
interest, if any, in said award; provided, however, Lessor shall have no interest in any award made to Lessee for loss of business or goodwill. In the event that fifty percent (50%) or more of the
building area or fifty percent (50%) or more of the value of the Office Complex is taken by public authority under the power of eminent domain, then either party may terminate this Lease by
delivering, within sixty (60) days after possession is taken, written notice thereof to the other party, which termination shall be effective as of the date ninety (90) days after such
termination notice is given.

Section 12.2 Lessee's Participation.Provisions in this Article 12 to the contrary notwithstanding, Lessee
shall have the right to prove in any condemnation proceedings and to receive any separate award which may be made for damages to or condemnation of Lessee's movable trade fixtures and equipment and
for moving expenses; provided, however, Lessee shall in no event have any right to receive any award for its interest in this Lease or for loss of leasehold. Provisions in this Article 12 to
the contrary notwithstanding, in the event of a partial condemnation of the Office Complex or the Premises and this Lease is not terminated, Lessor shall, at Lessee's sole cost and expense (to the
extent that any condemnation award or settlement is insufficient), restore the Premises and Office Complex to a complete architectural unit and the Base Rent provided for herein during the period from
and after the date of delivery of possession pursuant to such proceedings to the termination of this Lease shall be reduced to a sum equal to the product of the Base Rent provided for herein
multiplied by a fraction, the numerator of which is the fair market rent of the Premises after such taking and after same has been restored to a complete architectural unit, and the denominator of
which is the fair market rent of the Premises prior to such taking.

ARTICLE 13  SURRENDER OF PREMISES

Section 13.1 Surrender of Possession.On the last day of the term of this Lease, or on the sooner termination thereof,
Lessee shall peaceably surrender the Premises in good condition and repair

expense, remove all of its property and trade fixtures and equipment from the Premises, and all property not removed shall be deemed abandoned following the expiration of ten (10) days after
termination of this Lease. Lessee hereby appoints Lessor its agent to remove all abandoned property of Lessee from the Premises upon termination of this Lease and to cause its transportation and
storage for Lessee's benefit, all at the sole cost and risk of Lessee and Lessor shall not be liable for damage, theft, misappropriation or loss thereof and Lessor shall not be liable in any manner in
respect thereto. Lessee
shall pay all reasonable costs and expenses of such removal, transportation and storage. Lessee shall leave the Premises in good order, condition and repair, reasonable wear and tear and damage from
fire and other casualty or which is the responsibility of Lessor excepted. Lessee shall reimburse Lessor within thirty (30) days following its receipt of written demand for any expenses
incurred by Lessor with respect to removal, transportation, or storage of abandoned property and with respect to restoring said Premises to the condition required by this Lease. All alterations,
additions and fixtures, other than Lessee's furniture, personal property, trade fixtures and equipment which have been made or installed by either Lessor or Lessee upon the Premises, shall remain the
property of Lessor and shall be surrendered with the Premises as a part thereof. If the Premises are not surrendered at the end of the term or sooner termination thereof, Lessee shall indemnify Lessor
against loss or liability resulting from delay by Lessee in so surrendering the Premises, including, without limitation, claims made by any succeeding tenants founded on such delay and any attorneys'
fees resulting therefrom. Lessee shall promptly surrender all keys for the Premises to Lessor at the place then fixed for the payment of rent and shall inform Lessor of combinations on any vaults,
locks and safes left on the Premises.

Section 13.2 Lessee Retaining Possession.In the event Lessee remains in possession of the Premises after expiration

provisions, conditions and obligations of this Lease insofar as the same can be applicable to a month-to-month tenancy, except that the Base Rent shall be escalated to Lessor's
then current base rent for the Premises according to Lessor's then current rental rate schedule for prospective tenants, but not in excess of 150% of the Base Rent otherwise payable under the Lease.
In the event Lessee remains in possession of the Premises after expiration of this Lease and without the execution of a new lease and without Lessor's written consent, Lessee shall be deemed to be
occupying the Premises without claim of right and Lessee shall pay Lessor for all costs arising out of loss or liability resulting from delay by Lessee in so surrendering the Premises as above
provided and shall pay a charge for each day of occupancy an amount equal to one hundred fifty percent (150%) of the Base Rent and Additional Rent (on a daily basis) payable under this Lease upon
expiration.

46

or without notice or demand and without limiting Lessor in the exercise of any right or remedy which Lessor may have, Lessor shall be entitled to the rights and remedies set forth below.



47

---





48

---



Section 14.3 Written Notice of Termination Required.Lessor shall not be deemed to have terminated this Lease and the
Lessee's right to possession of the leasehold or the liability of Lessee to pay Rent thereafter to accrue or its liability for damages under any of the provisions hereof, unless Lessor shall have
notified Lessee in writing that it has so elected to terminate this Lease. Lessee covenants that the service by Lessor of any notice pursuant to the applicable unlawful detainer statutes of the state
in which the Office Complex is located and the Lessee's surrender of possession pursuant to such notice shall not (unless Lessor elects to the contrary at the time of, or at any time subsequent to the
service of, such notice, and such election be evidenced by a written notice to Lessee) be deemed to be a termination of this Lease or of Lessee's right to possession thereof.

Section 14.4 Remedies Cumulative; No Waiver.All rights, options and remedies of Lessor contained in this Lease shall
be construed and held to be cumulative, and no one of them shall be exclusive of the other, and Lessor shall have the right to pursue any one or all of such remedies or any other remedy or relief
which may be provided by law whether or not stated in this Lease, except as otherwise expressly set forth herein. No waiver by Lessor of a breach of any of the terms, covenants or conditions of this
Lease by Lessee shall be construed or held to be a waiver of any succeeding or preceding breach of the same or any other term, covenant or condition therein contained. No waiver of any default of
Lessee hereunder shall be implied from any omission by Lessor to take any action on account of such default if such default persists or is repeated, and no express waiver shall affect default other
than as specified in said waiver. The consent or approval by Lessor to or of any act by Lessee requiring Lessor's consent or approval shall not be deemed to waive or render unnecessary Lessor's
consent to or approval of any subsequent similar acts by Lessee.

Section 14.5 Legal Costs.The prevailing party in any dispute hereunder shall be entitled to recover, upon demand, for
any reasonable costs or expenses incurred in connection with any breach or default under this Lease, whether or not suit is commenced or judgment entered. Such costs shall include reasonable legal
fees and costs incurred for the negotiation of a settlement, enforcement of rights or otherwise. Furthermore, if any action for breach of or to enforce the provisions of this Lease is commenced, the
court in such action shall award to the party in whose favor a judgment is entered a reasonable sum as attorneys' fees and costs. Such attorneys' fees and costs shall be paid by the losing party in
such action. Lessee shall also indemnify Lessor against and hold Lessor harmless from all

49

---

costs, expenses, demands and liability incurred by Lessor if Lessor becomes or is made a party to any claim or action (a) instituted by Lessee, or by any third party against Lessee;
(b) for foreclosure of any lien for labor or material furnished to or for Lessee or such other person; (c) otherwise arising out of or resulting from any act or transaction of Lessee or
such other person; or (d) necessary to protect Lessor's interest under this Lease in a bankruptcy proceeding, or other proceeding under Title 11 of
the United States Code, as amended. Lessee shall defend Lessor against any such claim or action at Lessee's expense with counsel reasonably acceptable to Lessor or, at Lessor's election, Lessee shall
reimburse Lessor for any legal fees or costs incurred by Lessor in any such claim or action.

In
addition, Lessee shall pay Lessor's reasonable attorneys' fees incurred in connection with Lessee's request for Lessor's consent in connection with any act which Lessee proposed to do
and which requires Lessor's consent.

Section 14.6 Waiver of Damages for Reentry.Lessee hereby waives all claims by Lessor's reentering and taking
possession of the Premises or removing and storing the property of Lessee as permitted under this Lease and will save Lessor harmless from all losses, costs or damages occasioned Lessor thereby. No
such reentry shall be considered or construed to be a forcible entry by Lessor.

ARTICLE 15  SUBORDINATION/ESTOPPEL

Section 15.1 Lease Subordinate.This Lease shall be subject and subordinate to any mortgage, deed of trust or ground
lease now or hereafter placed upon the Premises, the Office Complex, the Property, or any portion thereof by Lessor, its successors or assigns, and to amendments, replacements, renewals and extensions
thereof. Lessee agrees at any time hereafter, within ten (10) days following Lessee's receipt of written demand, to execute and deliver any instruments, releases, or other documents that may be
reasonably required for the purpose of subjecting and subordinating this Lease, as above provided, to the lien of any such mortgage, deed of trust or ground lease. It is agreed, nevertheless, that as
long as Lessee is not in default beyond any applicable curative periods in the payment of Base Rent, Additional Rent, and the payment of other charges to be paid by Lessee under this Lease, and the
performance of all covenants, agreements and conditions to be performed by Lessee under this Lease, then neither Lessee's right to quiet enjoyment under this Lease, nor the right of Lessee to continue
to occupy the Premises and to conduct its business thereon, in accordance with the terms of this Lease as against any lessor, lessee, mortgagee, trustee, or their successors or assigns shall be
interfered with.

Section 15.2 Attornment.The above subordination shall be effective without the necessity of the execution and
delivery of any further instruments on the part of Lessee to effectuate such subordination. Notwithstanding anything hereinabove contained in this Article 15, in the event the holder of any
mortgage, deed of trust or ground lease shall at any time elect to have this Lease constitute a prior and superior lien to its mortgage, deed of trust or ground lease, then, and in such event, upon
any such holder or landlord notifying Lessee to that effect in writing, this Lease shall be deemed prior and superior in lien to such mortgage, deed of trust, ground lease, whether this Lease is dated
prior or subsequent to the date of such mortgage, deed of trust or ground lease and Lessee shall execute such attornment agreement as may be reasonably requested by said holder or landlord.

Section 15.3 Lessee's Notice of Default.Lessee agrees, provided the mortgagee, ground lessor or trust deed holder
under any mortgage, ground lease, deed of trust or other security instrument shall have notified Lessee in writing (by the way of a notice of assignment of lease or otherwise) of its address, Lessee
shall give such mortgagee, ground lessor or trust deed holder or other secured party ("Mortgagee"), simultaneously with delivery of notice to Lessor, by registered or certified mail, a copy of any
such notice of default served upon Lessor. Lessee further agrees that said Mortgagee shall have the right to cure any alleged default during the same period that Lessor has to cure such default.

Lease as modified is in full force and effect and stating the modifications); (b) the dates to which the rent and other charges have been paid; (c) Lessor is not in default in any
provision of this Lease or, if in default, the nature thereof specified in detail; (d) the amount of monthly rental currently payable by Lessee; (e) the amount of any prepaid rent, and
(f) such other matters as may be reasonably requested by Lessor or any mortgagee or prospective purchaser of the Office Complex.

If
Lessee does not deliver such statement to Lessor within such twenty (20) day period, Lessor and any prospective purchaser or encumbrancer of the Premises or the Office Complex
may conclusively presume and rely upon the following facts: (i) that the terms and provisions of this Lease have not been changed except as otherwise represented by Lessor; (ii) that
this Lease has not been canceled or terminated and is in full force and effect, except as otherwise represented by Lessor; (iii) that the current amounts of the Base Rent and Security Deposit
are as represented by Lessor and that any changes made against the Security Deposit are uncontested and valid; (iv) that there have been no subleases or assignments of the Lease;
(v) that not more than one month's Base Rent or other charges have been paid in advance; and (vi) that Lessor is not in default under the Lease. In such event, Lessee shall be estopped
from denying the truth of such facts.

the Commencement Date hereof Lessor shall deliver to Lessee an agreement executed by the holder of any mortgage lien against the Office Complex confirming its agreement not to disturb Lessee's

cured within the applicable cure period, to take such action as may be required to have been taken by Lessor under the Lease, in which event Lessor agrees to pay to Lessee within thirty
(30) days after receipt of written notice from Lessee (with accompanying paid invoices) all reasonable cost and expenses incurred by Lessee in connection therewith, failing which Lessee shall
be entitled to offset such sums against the Rent next becoming due under the Lease; provided, such offset shall not exceed more than twenty percent (20%) of monthly Base Rent payable each month until

part of Lessor are concerned shall be limited to mean and include only the owner or owners of the Office Complex at the time in question, and in the event of any transfer or transfers or conveyances
the then grantor, provided that the grantee expressly assumes the obligations of Lessor hereunder, shall be automatically freed and released from all personal liability accruing from and after the
date of such transfer or conveyance as respects the performance of any covenant or obligation on the part of Lessor contained in this Lease to be performed, it being intended hereby that the covenants
and obligations contained in this Lease on the part of Lessor shall be binding on the Lessor, its successors and assigns, only during and in respect to their respective successive periods of
ownership.

In
the event of a sale or conveyance by Lessor of the Office Complex, the same shall operate to release Lessor from any future liability upon any of the covenants or conditions herein

in and to this
Lease. This Lease shall not be affected by any such sale or conveyance, and Lessee agrees to attorn to the purchaser or grantee, which shall be personally obligated on this Lease only so long as it is

current lease or renewal term, as the case may be. In the event a renewal agreement has not been executed at least one hundred twenty (120) days prior to the expiration date of the current

notification from Lessee of its intent to exercise each renewal option, Lessor shall, within fifteen (15) days thereafter, notify Lessee in writing of the Base Rent for the
applicable renewal term; Lessee shall, within fifteen (15) days following receipt of same, notify Lessor in writing of the acceptance or rejection of the proposed Base Rent. In the event of
rejection by Lessee, Lessee may rescind the exercise of such renewal option by written notice to Lessor within such fifteen (15) day period for acceptance or rejection. If Lessee does not so

| | Re: | Office Lease dated as of November 1, 2001 (the "New Lease"), between EXE Technologies, Inc. ("Lessee") and BLI-8787, Ltd. ("Lessor") for 8777 and 8787 Stemmons Freeway, in Dallas, Texas (the "Premises")
| | --- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Dear
Ms. Hadik:

Lessor
and Lessee previously executed an Office Lease for the Premises dated May 18, 1999, as amended by Amendment No. 1 to Office Lease dated February 22, 2000
(collectively, the "Previous
Lease"). Lessee and Lessor are executing the New Lease as a restatement of the Previous Lease in its entirety, with the prior written approval of Lessor's lenders.

As
a condition to the execution of the New Lease, Lessor and Lessee agree that all claims under the Previous Lease are waived and released, subject to the final reconciliation of the
following matters: (a) refund to Lessee of November rent under the Previous Lease; (b) payment to Lessor of November rent due under the New Lease; (c) refund to Lessee of rent
overpayments, if any, under the Previous Lease; (d) the following repairs shall be completely by Lessorreplace shrubbery around parking garage, repair/replace various window and
entry door deficiencies in Towers I and II, reseal skylights, replace door felts/sweeps and adjust, and replace two (2) spandrel glass windows (the parties agreeing that Lessor is responsible
under the New Lease for the following structural repairs to the parking garageconcrete repair/patching, sealant placement/replacement, deflection repair at broken double "T" connections);
(e) payment to Lessor of prorated additional rent for operating expenses for the first ten months of 2001, under the Previous Lease; (f) reimbursement to Lessor for operating expenses
paid by Lessor in November for which Lessee is responsible under the New Lease; (g) payment to Lessor of prorated additional rent for taxes and insurance for the first ten months of 2001, under
the Previous Lease; and (h) reimbursement to Lessor for taxes and insurance for the last two months of 2001 for which Lessee is responsible under the New Lease. The parties will act in good
faith to complete this final reconciliation as soon after the execution of the New Lease as possible.

Under
the New Lease, the parties agree that Lessor will provide reasonable documentation to Lessee to support all amounts of additional rent to be paid by Lessee. All real estate taxes
and other impositions which Lessee is required to pay as additional rent, may be appealed at Lessee's request and sole expense (and with Lessor's consent which will not be unreasonably withheld,
conditioned or delayed). The appeal will be pursued, at Lessor's election, in Lessor's name and by counsel of its selection reasonably acceptable to Lessee, or in Lessee's name and by counsel of its
selection reasonably acceptable to Lessor. In either case, Lessor and Lessee will reasonably cooperate with each other in the pursuit of the appeal.

Please
evidence your agreement with the terms hereof by executing this letter in the space provided below.
