3.1. Extension Term. The Tenant shall have the right to extend the Initial Term for up to two (2) additional five (5) year periods (each, an “Extension Term”; the Initial Term and all exercised Extension Terms being collectively referred to as the “Term”) following the expiration of the Initial Term or the first Extension Term by providing the Landlord with written notice of the exercise of such right no more than eighteen (18) months and no less than six (6) months prior to the expiration of the Initial Term or first Extension Term, as applicable. In the event the Tenant does not exercise its right to the Extension Term, then this Lease shall expire effective as of the expiration date of the Initial Term or the first Extension Term, as applicable.

3.2. Terms and Conditions. All terms and conditions in this Lease shall remain in force and effect during the Term unless otherwise specified herein or agreed to in writing between the Landlord and the Tenant.

4.1. Tenant Requested Improvements. Any and all Tenant Requested Improvements shall be requested in writing by the Tenant and, subject to the Landlord’s approval in writing of the making of such proposed Tenant Requested Improvements shall be completed (i) under the supervision of Landlord at the Tenant’s own cost and expense, (ii) by the Landlord or (iii) by a third party contractor identified by the Tenant after soliciting bids, and approved by Landlord in writing.

4.2. Reimbursement. Any and all amounts expended for the Tenant Requested Improvements by Landlord plus a Construction Development Fee to be agreed upon and attached to this Lease as Schedule 4.2 prior to construction by the Tenant and the Landlord in an amount relative to the type of the Tenant Requested Improvements, will be collected as Additional Rent as provided in Paragraph 5.2 hereof.

5. RENT. In exchange for the leasehold rights and interests in and to the Property granted to the Tenant under this Lease, the Tenant agrees to pay to the Landlord the following amounts:

5.1. Base Rent. The monthly Base Rent due from Tenant shall be $5,750, which is an amount equal to ten percent (10%) of the total Landlord Improvement Costs as of the Effective Date divided by twelve (12).

5.2 Additional Rent. Additional Rent will be charged to the Tenant for Tenant Requested Improvements that Landlord agrees to fund on all monthly invoices after completion of such Tenant Requested Improvement in an amount that is equal to the sum of the total out-of-pocket expense paid by the Landlord directly attributable to such Tenant Requested Improvements divided by the remaining months left in the Initial Term or Extension Term of this Lease, as the case may be, at the time of completion of the Tenant Requested Improvement.

5.3. CPI Rent Escalation. At the beginning of each Lease Year, the Rent payable by Tenant shall be increased in an amount equal to the product of the Rent times a number equal to the percentage increase in the CPI over a 12 month period, calculated by using the most recently published CPI and the CPI published 12 months earlier.

The Tenant shall have one hundred eighty (180) days after receipt of each invoice to deliver written notice to Landlord, in order to audit, at the Tenant’s expense, Landlord’s records related to the expenses associated with Tenant Requested Improvements causing an increase in Additional Rent for said invoice. Under no circumstances does the Tenant’s right to review records relieve the Tenant from its obligation to make timely payment as required hereunder.

5.6. Payment. Any and all amounts charged as Rent shall be due and payable in advance on the first day of each calendar month. Other than the obligation to timely remit payments, no delay by the Landlord in providing the monthly invoice called for hereunder shall relieve the Tenant from its obligations hereunder. Payment of the Rent shall be made to the Landlord at 14301 Caliber Drive, Suite 300, Oklahoma City, Oklahoma 73134, or such other place as the Landlord may designate in writing. All payments of Rent shall be made without deduction, set· off, discount or abatement in lawful money of the United States.

The Tenant shall obtain any and all necessary permits for any such authorized alterations prior to commencing the same. Upon completion, the same shall be inspected, as appropriate or as required, by the appropriate officials. Any deficiencies and/or violations identified or noted by such officials shall be repaired, replaced and/or remedied by the Tenant at the Tenant’s sole expense and in the time frame required by such official related to such deficiency or violation or otherwise within a reasonable time frame. Any and all Permanent Fixtures and other alterations made to the Property shall remain the sole property of the Landlord upon the expiration or termination of this Lease, and the Tenant shall not be entitled to reimbursement or offset for the same. The Tenant shall have the right to remove Tenant’s Property within thirty (30) days after the end of the Term or the termination of the Tenant’s right to use or possess the Property, provided all other conditions of the Lease have been satisfied. Any damage caused as a result of removal of Tenant’s Property may be repaired by the Landlord at the Tenant’s sole expense. All of Tenant’s Property not removed by Tenant within thirty (30) days shall be deemed abandoned and become property of the Landlord; however, the Landlord shall retain the right to remove any of Tenant’s Property that is abandoned and charge Tenant for costs of removal and/or repair. In the event that any liens or other encumbrances are filed against the Property related to or arising from any such permitted alteration, the Tenant shall be solely obligated and responsible for, and shall pay all costs including attorney’s fees and costs, associated with the immediate removal of such lien or encumbrance.

affiliated and subsidiary companies and entities, and their respective directors, officers, agents and employees as additional insureds.

15.3. The Tenant shall furnish the Landlord with certificates of insurance in form and substance satisfactory to the Landlord evidencing insurance coverage and provisions provided for in this Lease. Failure of the Tenant to furnish such evidence of insurance coverage shall not be considered a waiver by the Landlord of the Tenant’s obligation to provide such insurance and such evidence. All insurance certificates shall include the following statement unless the Landlord approves alternative language:

“Caliber Wyoming Properties LLC, and its parent, affiliated or subsidiary companies and entities and their respective directors, officers, agents and employees are named as additional insured on all above policies (except Worker’s Compensation) and waiver of subrogation in favor of Caliber Wyoming Properties LLC, and each its parent, affiliated or subsidiary companies and entities, and their respective directors, officers, agents and employees applies as required by written contract. No less than thirty (30) days prior written notice shall be given Caliber Wyoming Properties LLC in the event of material alternation to or cancellation of the coverage evidenced by all above policies (except Worker’s Compensation).”

16. ASSIGNMENT. Except as set forth below and except for an assignment to a Permitted Transferee after notice to the Landlord fifteen (15) days prior to the assignment, the Tenant shall not sell, pledge or otherwise encumber or grant a lien upon or against the Property or any interest in this Lease, and the Tenant shall not sublease all of the Property or assign any of its rights, or delegate any of its duties, obligations or responsibilities, under this Lease without the Landlord’s prior written consent, which consent may be withheld, conditioned or delayed at the Landlord’s sole discretion. Consent by the Landlord to any assignment or sublease shall not be deemed to be a consent to any subsequent assignment or sublease. Any encumbrances, assignment, sublease or transfer without the prior written consent of the Landlord, whether voluntarily, by operation of law or otherwise, are void. The Tenant agrees that the Landlord may assign, sell or encumber all of this Lease and the payments hereunder, and upon written notice, the Tenant shall pay to such assignee all Rent and other sums due under or to become due under this Lease. Should the Tenant desire to assign this Lease or sublease the Property the Tenant shall give the Landlord written notice no later than fifteen (15) days in advance of the proposed effective date of the proposed assignment or sublease, specifying: (a) the name, current address, and business of the proposed Permitted Transferee, assignee, or sublessee, (b) the amount and location of the space within the Property proposed to be subleased, if applicable, (c) the proposed effective date and duration of the assignment or sublease, (d) the proposed rent and all consideration to be paid

-7-

to the Tenant by such assignee or sublessee, and (e) a financial statement, business resume and other information as the Landlord may reasonably request to evaluate the proposed Permitted Transferee, assignee, or sublessee. The Landlord shall have thirty (30) days following receipt of such notice and other information requested by the Landlord to elect one of the following options: (i) refuse to allow assignment or sublease if in the reasonable exercise of Landlord’s judgment it determines that (a) the financial condition and general reputation of the proposed Permitted Transferee, assignee, or subtenant are not consistent with the extent of the obligation undertaken by the proposed assignment or sublease; or (b) the proposed business to be conducted in the Demised Premises is not appropriate for the Property, will cause unreasonable wear to the Property, or is prohibited by applicable law; or (ii) to terminate this Lease as to the space so affected as of the proposed effective date set forth in the Tenant’s notice, in which event the Tenant shall be relieved of all further obligations hereunder as to such space and all other provisions of this Lease which expressly survive the termination hereof; or (iii) to permit Tenant to assign or sublease such space; provided however, if the Landlord provides the Tenant with notice of the exercise of the Landlord’s right to terminate all or any portion of this Lease pursuant to this Section, the Tenant may withdraw its request to assign this Lease or sublease the Property, as applicable, by providing notice prior to the effective date of the termination and this Lease shall continue as though the Tenant never requested to assign the Lease or sublease all or a portion of the Property, as applicable. The Tenant shall deliver to the Landlord copies of all documents executed in connection with any permitted assignment or subletting, which documents shall be in form and substance reasonably satisfactory to the Landlord and which shall require any Permitted Transferee, assignee, or sublessee to assume performance of all terms of this Lease to be performed by the Tenant or any subtenant to comply with all the terms of this Lease to be performed by the Tenant. In no event shall an approved assignment or sublease relieve the Tenant from its obligation to fully perform all the terms, conditions, and covenants of this Lease. If this Lease shall be assigned, or if the Property be sublet or occupied by any person or persons other than Tenant, Landlord may, after default by Tenant, collect rent from the assignee, subtenant, or occupant, and apply the net amount collected to the rent herein reserved, but no assignment, subletting, occupancy, or collection of rent shall be deemed a waiver of the covenants in this Section, nor shall it be deemed acceptance of the assignee, subtenant, or occupant as a tenant, or a release of Tenant from the full performance by Tenant of all the terms, conditions, and covenants of this Lease.

17. SUBORDINATION. This Lease shall be subject and subordinate to any mortgage, deed of trust, deed to secure deed, security interested granted by Landlord, or similar encumbrance (a “Mortgage”) presently existing or hereafter arising upon any of the Property and to any renewal, extension or refinancing thereof, and the Tenant agrees that any holder of such Mortgage shall have the right at any time to subordinate such Mortgage to this Lease on such terms and subject to such conditions as the holder of such Mortgage may deem appropriate in its discretion. The provisions of the foregoing sentence shall be self-operative and no further instrument of subordination shall be required; provided, however the Tenant agrees within twenty (20) days after demand to execute and deliver any instrument subordinating this Lease or attorning to the holder of any such Mortgage as the Landlord may request. As a condition to the subordination contemplated by this Section, the Landlord shall use reasonable efforts to obtain from the holder of any Mortgage affecting the Property an agreement, in writing, for itself, its successors and assigns, that the rights of the Tenant under the Lease shall not be terminated, and the possession of the Property by the Tenant shall not be disturbed by any holder of any Mortgage or by any

-8-

proceeding on the debt which any such Mortgage secures, or by any person, firm or corporation whose rights were acquired as a result of such proceeding or by virtue of a right or power contained in any such Mortgage or the debt secured thereby and that any sale at foreclosure will be subject to this Lease, so long as the Tenant performs its obligations hereunder in accordance with the terms hereof. If the Property is subject to a Mortgage as of the date of this Lease, the Landlord shall use reasonable efforts to provide the Tenant with the agreement contemplated by the forgoing sentence from the holder of such Mortgage within sixty (60) days from the date of this Lease.

18. ESTOPPEL. Each party agrees to execute and deliver to the other party a certificate or statement certifying that (i) this Lease is unmodified and in full force and effect (or if there have been modifications, that the same is in full force and effect as so modified), (ii) the expiration date of this Lease, (iii) the dates to which Rent and other charges payable under this Lease have been paid, (iv) the Tenant has accepted possession of the Property and that any improvements required by the terms of this Lease to be made by the Landlord have been completed to the satisfaction of the Tenant, (v) no Rent has been paid more than thirty (30) days in advance of its due date, (vi) to the delivering party’s knowledge, the requesting party is not in default hereunder (or if not in default, the nature of such alleged default), and (vii) such other matters as the Landlord or any holder of a Mortgage shall reasonably require.

19. DESTRUCTION OR DAMAGE. In the event of partial or total destruction of the Property or improvements by fire or other casualty, the Landlord shall, as promptly as practicable, repair, reconstruct or replace the portions of the Property or the improvements destroyed in a good and workmanlike manner so as to provide for the continuation of the Tenant’s use of the Property for the permitted use, subject to the provisions hereof. During the period of repairs or restoration, this Lease shall continue in full force and effect and there shall be no abatement of Rent. If (i) the Property or improvements are so extensively destroyed by fire or other casualty so as to render the Property unsuitable for the Tenant’s use of the Property in the same manner as the Tenant’s use of the Property at the time of such fire or other casualty, and (ii) the Landlord’s contractor has notified Landlord that it estimates that the period of time required to repair, reconstruct or replace the portions of the Property or improvements destroyed, so as to provide for the continuation of the Tenant’s use in the same manner as the Tenant’s use of the Property at the time of such fire or other casualty, shall exceed one hundred eighty (180) days, then the Tenant may terminate this Lease by turning over any and all insurance proceeds related to the Property to Landlord and giving written notice to the Landlord within ninety (90) days after the date of such destruction. In the event of termination pursuant to this Section, this Lease shall terminate as of, and Rent shall be appropriately apportioned through and abated from and after, the first rental payment date occurring after the delivery of the notice of termination. If the Tenant has the option to terminate this Lease pursuant to this Section but elects not to so terminate, there shall be no abatement of Rent, and the Landlord shall, as promptly as practicable, repair, reconstruct or replace the portions of the Property or the improvements destroyed in a good and workmanlike manner so as to provide for the continuation of the Tenant’s use of the Property for the permitted use.

20. EMINENT DOMAIN. If the whole of the Property is lawfully taken by condemnation or in any other manner for any public or quasi-public purpose, this Lease shall terminate as of the earlier of the date title vests or the date possession is given, and Rent shall be prorated to such date. If less than the whole of the Property or the improvements is so taken so as to render the

-9-

balance of the Property unsuitable for use by the Tenant in the same manner as Tenant’s use of the Property at the time of such taking, then Landlord shall have the right to improve the balance of the Property in such a manner that will permit the Tenant to use the Property in the same manner as Tenant’s use of the Property at the time of the taking. Such improvements shall include the replacement or construction of any improvements (in size, use and scope) lost as a result of the taking. Landlord’s obligation shall be limited to the consideration it receives as a result of the taking. In the event Landlord elects not to or is unable to improve the Property to permit the Tenant to use the Property in the same manner as Tenant’s use of the Property as of the taking, Landlord shall notify Tenant of such election or inability within fifteen (15) days of such taking and Tenant shall have ninety (90) days from such notice to terminate this Lease. Rent shall be prorated to the date of such termination. If this Lease continues in force upon such partial taking, the Rent shall be equitably adjusted according to the remaining area of the Property and the use thereof by Tenant.

21. MAINTENANCE AND REPAIRS. The Tenant shall be solely obligated and responsible for: (i) maintaining, normal wear and tear excepted, and repairing, any and all parts of the Property, including without limitation the roof of any and all structures located at the Property and all heating, air conditioning and ventilation service to any structures located at the Property (subject to Tenant’s right to avail itself of any manufacturer’s or contractor’s warranties on the HVAC); (ii) preventing and exterminating pests in and around the Property; (iii) maintaining any and all landscaping in and around the Property; and (iv) keeping the parking lot, sidewalks and entryways free and clear of all debris, snow and ice.

22. NO WARRANTIES. The Landlord makes no express or implied warranty of any kind whatsoever with respect to the Property, including, but not limited to, any warranty relating to the habitability of the Property.

23. SIGNS. The Tenant shall have the right, at the Tenant’s sole cost and expense, to install, erect and maintain upon the Property any signs as the Tenant may from time to time deem necessary or appropriate; provided, that any and all signs and installation shall comply with any and all applicable ordinances, rules, regulations and laws and shall not permanently damage or injure the Property. Upon the expiration or termination of the Lease, the Tenant shall cause, at the Tenant’s sole cost and expense, all such signs to be immediately removed. If a sign is not immediately removed upon the expiration or termination of the Lease, the sign shall become the sole property of the Landlord, and the sign will, at the Landlord’s option, be removed and disposed of by the Landlord. In the event a sign is removed by the Landlord, the Tenant shall be solely obligated and responsible for, and shall promptly reimburse the Landlord for, the cost of the removal and disposal of any sign.

24. EVENTS OF DEFAULT. The occurrence of any of the following shall be an Event of Default under this Lease: (i) the Tenant’s failure to pay the Rent or any other amount to be paid by the Tenant to the Landlord under this Lease within ten (10) days after the receipt of notice from the Landlord of delinquency; (ii) the Landlord or the Tenant fails to cure any material breach, default or failure to perform (except for payments of any amounts due to the Landlord under this Lease) any of the terms, conditions, covenants or agreements in this Lease within thirty (30) days after the breaching party receives written notice of such breach, default or failure, said cure period to be extended to sixty (60) days if the breaching party provides

-10-

evidence that it is using reasonable diligence to cure the default; (iii) the Tenant abandons, deserts or vacates the Property for more than ninety (90) days within any twelve (12) month period; or (iv) the Tenant becomes insolvent. For purposes of this Lease, a party shall be considered insolvent if the party: (i) applies for or consents to the appointment of a receiver, trustee or liquidator of its assets or properties; (ii) admits in writing its inability to pay debts as the same mature or become due; (iii) makes a general assignment for the benefit of creditors; (iv) has any material part of its assets or properties placed in the hands of a receiver, trustee or other officer or representative of a court or of creditors; (v) is adjudged bankrupt or institutes any voluntary proceeding in insolvency or bankruptcy or for readjustment, extension or composition of debts or for any other relief of debtors; or (vi) has any involuntary proceeding instituted against the party in insolvency or for readjustment, extension, or composition of debts, which proceeding is not dismissed within sixty (60) days after the filing of the commencement of the same; or (vii) has an entry by any court of a final non-appealable judgment against the party for damages in excess of $100,000.00 which the party does not pay within sixty (60) days [we discussed this last time, I am technically ok with this as the section it actually shortens their total time to cure if they are using reasonable diligence] or the institution of any levy, attachment, garnishment or charging order against the party for similar damages. If a party is adjudged bankrupt, or a trustee in bankruptcy is appointed for a party, the Landlord and the Tenant, to the extent permitted by law, agree and covenant to request that the trustee in bankruptcy determine within sixty (60) days thereafter whether to assume or to reject this Lease.

25. REMEDIES. Upon the occurrence of any Event of Default, the non-breaching party shall be entitled to all rights and remedies allowed by law or equity. In addition, the Landlord and the Tenant shall have the following rights and remedies, which may be pursued successively or cumulatively as the Landlord or the Tenant may elect without any notices or demands (which notices and demands are hereby waived) as a prerequisite to the exercise of any of its rights or remedies under this Lease, other than those notices and demands specifically required under this Lease.

25.1. Re-enter Property. The Landlord may re-enter the Property and cure any default of the Tenant, and upon demand, the Tenant shall immediately reimburse the Landlord for any and all costs and expenses incurred by the Landlord in curing any such default.

25.2. Terminate Lease. The Landlord may terminate this Lease by giving written notice to the Tenant. This Lease shall terminate as of the date stated in such notice, and the Tenant shall have no further rights, duties, obligations or responsibilities under this Lease, except accrued payment obligations and those expressly provided to survive the expiration or termination of this Lease.

25.3. Terminate Right to Use.

-11-

Rent accrued and unpaid for the period up to and including such termination date and all other amounts due to the Landlord including, but not limited to, any and all costs and expenses, court costs and attorneys’ fees incurred by the Landlord as a result of or connected with the Event of Default and in the enforcement of its rights and remedies under this Lease. Any termination of the Tenant’s right to use and possess the Property shall not release the Tenant, in whole or in part, from the Tenant’s duties, obligation and responsibilities under this Lease including, but not limited to, the payment of Rent and other amounts that may become due under this Lease for the remainder of the Term.

25.3.1. Reletting. The Landlord may relet all or any part of the Property for such time and upon such terms as the Landlord may determine.

25.3.2. Excess from Reletting. Any excess amount shall operate only as an offsetting credit against the amount of Rent due and owing as the same becomes due and payable, and the use of such offset shall not give, or be deemed to give, the Tenant any right, title or interest in or to such excess. No actions Landlord under this Section shall be construed as an eviction (constructive or otherwise) of the Tenant or as an election by the Landlord to terminate this Lease or shall operate to release the Tenant in whole or in part from any of the Tenant’s duties, obligations or responsibilities under this Lease. The Landlord may, at any time and from time to time, sue and recover judgment for any deficiencies remaining after the application of the proceeds of any such reletting.

25.4. Enforce Lease. The Landlord or the Tenant may enforce the provisions of this Lease and may enforce and protect their respective rights under this Lease by a suit or suits in equity or at law for the specific performance of any covenant or agreement contained in this Lease, or for the enforcement of any other appropriate legal or equitable remedy, including recovery of all moneys due or to become due from a party to the other.

25.5. Property Removed.

Neither party may unreasonably withhold its consent to the selection of a mediator, and the parties shall share the costs of the mediation equally.

The Landlord and the Tenant hereby waive any right to a trial by jury in a lawsuit involving any claim or controversy arising out of this Lease. The use of alternative dispute resolution shall not be construed under the doctrines of laches, waiver or estoppel to affect adversely the rights of either party.
