(a) Except as expressly otherwise provided herein, this Lease is intended to be, and shall be construed as, a gross lease, whereby under all circumstances and conditions (whether now or hereafter existing or within the contemplation of the parties), Landlord shall be solely responsible for and shall pay any and all expenses, costs, liabilities, taxes, obligations and charges whatsoever which shall arise or be incurred, or shall become due, during or in respect of the Term, in respect of or in connection with the Premises or the ownership, leasing, operation, management, maintenance, repair, use, occupancy, or any other aspect thereof, or any portion thereof. Notwithstanding the foregoing or anything else herein to the contrary, Tenant shall be responsible for payment of all utilities, including water, gas, electric and telephone service delivered to the Premises.

(b) The parties intend that the obligations of Tenant hereunder shall be separate and independent covenants and agreements and shall continue unaffected unless such obligations shall have been modified or terminated pursuant to an express provision of this Lease.

5. Permitted Use. The Premises shall be used for a sand transloading and storage facility and for no other purpose. Tenant agrees not to use or permit the use of the Premises for any purpose which is illegal, dangerous to life, limb or property or which, in Landlord’s sole judgment, creates a nuisance or which would increase the cost of insurance coverage with respect to the Premises. Tenant will conduct its business and control its agents, servants, employees, customers, licensees, and invitees in such a manner as not to interfere with, annoy or disturb other tenants, if any, or Landlord in the management of the Premises and the Land. Tenant will maintain the Premises in a clean and healthful condition, and comply with all laws, ordinances, orders, rules and regulations of any governmental entity with reference to the use, condition, configuration or occupancy of the Premises.

6. Compliance with Laws. Etc. Tenant covenants throughout the Term and any extended term of this Lease, at the sole cost and expense of Tenant, to comply promptly with all laws, ordinances, orders, rules, regulations and requirements of all federal, state and municipal governments and appropriate departments, commissions, boards and officers thereof (“Legal Requirements”), and the orders, rules and regulations of any applicable board of insurance

underwriters, or any other body exercising similar functions, foreseen or unforeseen, extraordinary as well as ordinary, which may be applicable to any aspect of the Premises (or to any adjoining public sidewalks and curbs) or to the use or the manner of use of the Premises, or to the restoration, repairing, replacing or rebuilding of the Premises provided for in this Lease, or in respect of any changes or alterations made by Tenant to the improvements, or any other aspect of the Premises and with the requirements of all insurance required hereunder to be maintained by Tenant.

7. Liens. Tenant shall not suffer or permit any mechanic’s, materialmen’s, vendor’s, supplier’s, laborer’s, or other similar liens (collectively, “Mechanic’s Liens”) to be filed against the Premises, or any part thereof, by reason of work, labor, services or materials supplied at the request of Tenant or any officer, director, employee or agent of Tenant. If any such mechanic’s lien shall at any time be filed against the Premises, or any part thereof, Tenant shall, within thirty (30) days after notice of the filing thereof, cause the same to be discharged of record by payment, deposit, bond, order of a court of competent jurisdiction or otherwise. If Tenant shall fail to cause such lien to be discharged within such thirty (30) day period, then, in addition to any other right or remedy of Landlord, Landlord may, but shall not be obligated to, discharge the same either by paying the amount claimed to be due (if bonding or deposit proceedings are insufficient to protect the material interests of Landlord) or by procuring the discharge of such lien by deposit or by bonding proceedings, and in any such event Landlord shall be entitled to reimbursement from Tenant upon demand.

(a) Tenant shall be liable for all taxes levied against personal property and trade fixtures placed by Tenant in the Premises. If any such taxes are levied against Landlord or Landlord’s property and if Landlord elects to pay the same or if the assessed value of Landlord’s property is increased by inclusion of personal property and trade fixtures placed by Tenant in the Premises and Landlord elects to pay the taxes based on such increase, Tenant shall pay to Landlord upon demand that part of such taxes for which Tenant is primarily liable hereunder.

(b) Tenant may, at its sole cost and expense, in its own name, dispute and contest any impositions by appropriate proceedings diligently conducted in good faith, but only after Tenant has deposited with Landlord the amount so contested and unpaid, which shall be held by Landlord without obligation of interest until the termination of the proceedings, at which time the amount(s) deposited shall be applied by Landlord toward the payment of the items held valid (plus any court costs, interest, penalties and other liabilities associated with the proceedings), and any excess shall be returned to Tenant. Tenant further agrees to pay to Landlord upon demand all court costs, interest, penalties and other liabilities relating to such proceedings. Tenant hereby indemnifies and agrees to hold harmless Landlord from and against any cost, damage or expense (including attorneys’ fees) in connection with any such proceedings.

9. Maintenance and Repair. Tenant shall, at its sole cost and expense, maintain the Premises, including, but not limited to the track, silos and other infrastructure and equipment, in a good and serviceable state of repair and condition, reasonable evidence of which has been provided to Landlord. Landlord will not be responsible to make any other foreseen or unforeseen, or ordinary or extraordinary changes or repairs which may be required to keep the

Premises in good (or any other) repair and condition; or in compliance with any applicable laws except as may otherwise be expressly provided herein. Except as expressly provided herein, Landlord shall not be required to maintain, repair or rebuild the improvements on the Premises or maintain the Premises. If Landlord does not perform the repairs, maintenance and replacements required pursuant to this Lease within thirty (30) days after receipt of written notice from Tenant; provided, however, that if any such repairs cannot be reasonably performed with said thirty (30) day period by the exercise of due diligence by Landlord, then the same shall not give rise to Tenant’s right to perform such repairs hereunder if within said thirty (30) day period Landlord commences the performance of such repairs and diligently prosecutes the same to completion, then Tenant shall have the right, but not the duty, to do said repairs, maintenance and replacements on behalf of Landlord and Tenant may offset the cost thereof, plus ten (10%) percent for overhead, against the Rent.

No assignment or subletting shall release Tenant from its obligations hereunder; and Tenant shall in any event be obligated to pay to Landlord as additional rent hereunder any consideration received by Tenant from any such assignment, sublease or other disposition which exceeds the Base Rent payable by Tenant hereunder for the equivalent time period and portion of the Premises and the costs to Tenant of completing such transaction.

(a) If, at any time during the Term of this Lease, there shall be a taking of twenty-five percent (25%) or more of the Land in condemnation proceedings or by any right of eminent domain (other than the taking by eminent domain for occupancy for a limited period), then at the option of Tenant, this Lease shall terminate on the date of such taking and the Base Rent and other charges payable by Tenant hereunder shall be apportioned and paid to the date of such taking.

Landlord shall have the right, at all reasonable times during the normal business hours of Tenant with prior notice to Tenant, to enter the Premises for the following reasons: general inspection; determining Tenant’s use of the Premises, determining if an Event of Default under this Lease has occurred; showing the Premises to a perspective purchaser or tenant; or remedying any failure by Tenant to perform its covenants hereunder.

23. Waiver of Subrogation. Anything in this Lease to the contrary notwithstanding, Landlord and Tenant hereby waive and release each other of and from any and all rights of recovery, claim, action or cause of action, against each other, their agents, officers and employees, for any loss or damage that may occur to the Premises or to improvements or personal property thereon, by reason of fire or the elements regardless of cause or origin, including negligence of Landlord or Tenant or their agents, officers and employees, to the extent such loss or damage is compensated out of insurance proceeds. Because this paragraph will preclude the assignment of any claim mentioned in it by way of subrogation or otherwise to an insurance company or any other person, each party to this Lease agrees immediately to give to each insurance company which has issued or will issue to such party policies of insurance covering all risk of physical loss, written notice of the terms of the mutual waivers contained in this paragraph, and to have the insurance policies properly endorsed, if necessary, to prevent the invalidation of the insurance coverages by reason of the mutual waivers contained in this paragraph.

24. Quiet Enjoyment. Upon payment of the required rents and performance of the terms, covenants and agreements contained in this Lease, Tenant shall peaceably and quietly have, hold and enjoy the Premises during the Term.

25. Holding Over. In the event of holding over by Tenant after the expiration or termination of this Lease, the hold over shall be as a tenant-at-will and all of the terms and provisions of this Lease shall be applicable during that period, except that Tenant shall pay Landlord rental for the period of such hold over an amount equal to 120% of the Rent which would have been payable by Tenant had the hold over period been a part of the original Term of this Lease. The Rent payable during this hold over period shall be payable to Landlord on demand. No holding over by Tenant, whether with or without the consent of Landlord, shall operate to extend this Lease except as otherwise expressly provided.

26. Surrender. Upon the expiration or termination of the Term of this Lease, Tenant shall surrender the Premises to Landlord. Tenant shall remove from the Premises on or prior to such expiration or termination all non-fixture personal property situated thereon which is not owned by Landlord. Property not so removed shall, at Landlord’s option, become the property of Landlord, and if subsequently disposed of by Landlord the proceeds of such disposition shall become the property of Landlord, and Landlord may cause such property to be removed from the Premises and disposed of, but the cost of any such removal and disposition and of repairing any damage caused by such removal shall be borne by Tenant.

27. Indemnification. Tenant shall pay, and shall protect, indemnify and save harmless Landlord, its officers, directors, employees, agents and representatives from and against, all liabilities, losses, damages, costs, expenses (including reasonable attorneys’ fees and expenses), causes of action, suits, claims, demands or judgments of any nature arising from or relating to the actions or inactions of Tenant, its agents, employees, contractors or invitees as follows: (a) injury to or death of any person, or damage to or loss of property, on the Premises or on adjoining sidewalks, streets or ways, or otherwise connected with the use, condition or occupancy of the Premises, (b) any breach by Tenant of any of its obligations under this Lease, (c) any contest referred to in Section 8, (d) any damage or injury to Landlord or any other property or any person on the Premises, (e) any damage or injury to the Premises or Landlord by reason of any act or thing done by Tenant (or any of the foregoing related parties) or any condition on the Premises, (f) any other action or inaction of Tenant relating to the Premises, or (g) any other matters which arise during the Term in respect of the Premises, in the case of any of the foregoing, except if such matter arises due to the negligence or willful misconduct of Landlord, its agents, employees, contractors or invitees. The provisions of this Section 27 shall survive the expiration or sooner termination of this Lease.

28. Landlord’s Liability. Notwithstanding anything in this Lease to the contrary, Tenant hereby agrees that the liability of Landlord hereunder in the event of a claim against Landlord shall extend only to Landlord’s interest in the Premises. Except to such extent, no recourse whatsoever shall be had under this Lease against (a) Landlord, or any incorporator or any stockholder, officer, director, employee or agent of Landlord or any predecessor or successor corporation, (b) any legal representative, heir, successor or assign of any thereof, or (c) any assets of Landlord other than its interest in the Premises. Tenant shall not sue to recover damages for a default by Landlord hereunder until after first providing Landlord with at least thirty (30) days prior written notice of the basis thereof and the opportunity to cure same within such thirty (30) day period.

29. Notices. All notices, demands, designations, certificates, requests, offers, consents, approvals and other instruments given pursuant to this Lease shall be given by personal delivery (provided a signed receipt therefor is obtained), overnight courier service or prepaid registered or certified mail, as follows:

or to such other person or address as either party shall specify by written notice to the other party. All notices hereunder shall be deemed given when received.

(a) This Lease shall be subordinate to any first lien deed of trust, mortgage, or other security instrument (a “Mortgage”), or any ground lease, master lease, or primary lease (a “Primary Lease”), that now or hereafter covers all or any part of the Premises (the mortgagee under any Mortgage or the lessor under any Primary Lease is referred to herein as “Landlord’s Mortgagee”), and Tenant shall within three (3) days after receiving a request from Landlord or Landlord’s Mortgagee, execute such agreements confirming such subordination as such party may reasonably request.

(b) Tenant shall attorn to any party succeeding to Landlord’s interest in the Premises, whether by purchase, foreclosure, deed in lieu of foreclosure, power of sale, termination of lease, or otherwise, upon such party’s request, and shall within three (3) days after receiving such party’s request shall execute such agreements confirming such attornment as such party may reasonably request.

(c) Tenant shall not seek to enforce any remedy it may have for any default on the part of the Landlord without first giving written notice by certified mail, return receipt requested, specifying the default in reasonable detail, to any Landlord’s Mortgagee whose address has been given to Tenant, and affording such Landlord’s Mortgagee a reasonable opportunity to perform Landlord’s obligations hereunder.

31. Estoppel Certificates. Tenant or Landlord will, from time to time, upon fifteen (15) days’ prior written notice from the other party, execute, acknowledge and deliver to the other party a certificate stating that this Lease is unmodified and in full force and effect (or, if there have been modifications, that this Lease is in full force and effect as modified, and setting forth such modifications) and the dates to which the Rent, additional rent and other sums payable hereunder have been paid, and either stating that, to the knowledge of the signer of such certificate, no default exists hereunder or specifying each such default of which the signer has knowledge and the steps being taken to remedy same. Any such certificate may be relied upon by the parties hereto and any prospective mortgagee or purchaser of the Premises.

32. Severability. Each provision hereof shall be separate and independent and the breach of any such provision by Landlord shall not discharge or relieve Tenant from its obligations to perform each and every covenant to be performed by Tenant hereunder. If any provision hereof or the application thereof to any person or circumstance shall to any extent be invalid or unenforceable, the remaining provisions hereof, or the application of such provision to persons or circumstances other than those as to which it is invalid or unenforceable, shall not be affected thereby, and each provision hereof shall be valid and shall be enforceable to the maximum extent permitted by law.

33. Successors and Assigns. All provisions contained in this Lease shall be binding upon, inure to the benefit of and be enforceable by, the respective legal representatives, successors and assigns of Landlord and Tenant to the same extent as if each such legal representative, successor and assign were named as a party hereto.

34. Amendments. This Lease may not be changed, modified or discharged except by a writing signed by Landlord and Tenant.

35. Governing Law. This Lease shall be governed by the laws of the State of Texas.

36. Entire Agreement. Except as otherwise provided in this Lease: no oral statement or prior written matter relating to the subject matter of this Lease shall have any force or effect, and all such statements and matters shall merge herein and be superseded hereby; and Tenant agrees that it is not relying on any representations or agreements other than those contained in this Lease, if any.

37. Counterparts. This Lease may be executed in any number of counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

(a) In the event that the Premises shall be damaged or destroyed by fire or other casualty insurable under the standard fire and extended coverage insurance, then, provided at least eighteen (18) months remain within the Term and provided that, in the opinion of Landlord’s architect, the Premises can be restored to usability within 120 days, Landlord shall proceed with reasonable diligence at its sole cost and expense to rebuild and repair the Premises. If the improvements shall be damaged or destroyed by uninsurable casualty, if, in the opinion of Landlord’s architect, the Premises cannot be restored to usability within 120 days, or if less than eighteen (18) months remain within the Term, then this Lease shall terminate effective of the date of such casualty unless Landlord shall give Tenant written notice within 60 days after the date of the casualty that Landlord undertakes to rebuild and repair the Premises. Except as otherwise agreed in writing by Tenant, Tenant may terminate this Lease in the event that the Premises are not actually restored to usability within 120 days after the occurrence of such casualty.

(b) Landlord’s obligation to rebuild and repair hereunder shall in any event shall be limited to restoring the improvements to substantially the condition in which they existed prior to the casualty, and Tenant agrees that promptly after completion of such work by Landlord it will proceed with reasonable diligence at its own cost and expense to rebuild, repair and restore its signs, fixtures, equipment and other items installed by Tenant. Rent shall abate for any period of time the Premises are substantially unusable by Tenant by reason of such casualty.

40. Signage. Tenant shall, during the Term of this Lease, have the right to maintain signs at the Premises advertising Tenant’s business; provided that such signage shall conform in all respects to the rules and regulations imposed by the City of Dilley, Texas.

IN WITNESS WHEREOF, Landlord and Tenant have caused this Lease to be duly executed and delivered as of the date first above written.
