If you are a prospective seller or landlord (owner) or a prospective buyer or tenant (buyer), you should know that the broker who lists the property for sale or lease is the owner’s agent. A broker who acts as a subagent represents the owner in cooperation with the listing broker. A broker who acts as a buyer’s agent represents the buyer. A broker may act as an intermediary between the parties if the parties consent in writing. A broker can assist you in locating a property, preparing a contract or lease, or obtaining financing without representing you. A broker is obligated by law to treat you honestly. IF THE BROKER REPRESENTS THE OWNER: The broker becomes the owner’s agent by entering into an agreement with the owner, usually through a written listing agreement, or by agreeing to act as a subagent by accepting an offer of sub agency from the listing broker. A subagent may work in a different real estate office. A listing broker or subagent can assist the buyer but does not represent the buyer and must place the interests of the owner first. The buyer should not tell the owner’s agent anything the buyer would not want the owner to know because an owner’s agent must disclose to the owner any material information known to the agent. IF THE BROKER REPRESENTS THE BUYER: The broker becomes the buyer’s agent by entering into an agreement to represent the buyer, usually through a written buyer representation agreement. A buyer’s agent can assist the owner but does not represent the owner and must place the interests of the buyer first. The owner should not tell a buyer’s agent anything the owner would not want the buyer to know because a buyer’s agent must disclose to the buyer any material information known to the agent. IF THE BROKER ACTS AS AN INTERMEDIARY: A broker may act as an intermediary between the parties if the broker complies with The Texas Real Estate License Act. The broker must obtain the written consent of each party to the transaction to act as an intermediary. The written consent must state who will pay the broker and, in conspicuous bold or underlined print, set forth the broker’s obligations as an intermediary. The broker is required to treat each party honestly and fairly and to comply with The Texas Real Estate License Act. A broker who acts as an intermediary in a transaction: (1) shall treat all parties honestly; (2) may not disclose that the owner will accept a price less than the asking price unless authorized in writing to do so by the owner; (3) may not disclose that the buyer will pay a price greater than the price submitted in a written offer unless authorized in writing to do so by the buyer; and (4) may not disclose any confidential information or any information that a party specifically instructs the broker in writing not to disclose unless authorized in writing to disclose the information or required to do so by The Texas Real Estate License Act or a court order or if the information materially relates to the condition of the property. With the parties’ consent, a broker acting as an intermediary between the parties may appoint a person who is licensed under The Texas Real Estate License Act and associated with the broker to communicate with and carry out instructions of one party and another person who is licensed under that Act and associated with the broker to communicate with and carry out instructions of the other party. If you choose to have a broker represent you, you should enter into a written agreement with the broker that clearly establishes the broker’s obligations and your obligations. The agreement should state how and by whom the broker will be paid. You have the right to choose the type of representation, if any, you wish to receive. Your payment of a fee to a broker does not necessarily establish that the broker represents you. If you have any questions regarding the duties and responsibilities of the broker, you should resolve those questions before proceeding. TENANT REPRESENTATION Tenant certifies that (broker) represents Tenant in the negotiation and/or site selection of commercial space for lease. Check if none . 11 BPMC.Lease Form.TX.March 2013 Tenant Initials

TENANT (signature and title) Elizabeth Hernandez TENANT (print name) 5/27/2016 Date City of Houston Smoking Ordinance Report Created by Linda Figler Reviewed & Revised by CKC/JKR DocuSign Envelope ID: 5257293A - 0C66 - 43A8 - 8383 - 494EAD469556 DocuSign Envelope ID: C29C8842 - B009 - 4317 - AE1B - 431CB200117A TENANT NOTIFICATION The City of Houston recently passed an amendment to the existing City Smoking Ordinance. In order to comply with the ordinance, the Landlord is responsible for notifying you, our valued tenant, about what this means for you. Here is a synopsis of what the ordinance requires. Effective November 26, 2002: Smoking is not allowed within 25 feet of any building entrance, interior or exterior. Smoking is not allowed in the building. This includes inside of the individual tenant suites and any of the tenant offices. An exception to the City Ordinance occurs if the following ventilation requirements are met: The “exception area”, or other exempt areas within a building, must have either a) a completely separate ventilation system from the building system, or b) a system that provides an air exchange at least every 15 minutes, and exhausts all exchanged air through ductwork directly to the exterior of the building. The exhausted air cannot be drawn into any occupied non - smoking area of the building. The ventilation system must be designed so that the air pressure where smoking is allowed is neutral to any adjacent occupied non - smoking area. The cost to install any such “exception area” is solely at the tenant’s expense. The amended ordinance also requires that each employer must adopt, implement and maintain a written employee smoking policy. The policy must accommodate the preference of non - smoking employees to work in a smoke free environment. A written copy of the policy must be provided to your employees within three weeks of the adoption of the policy. A written copy of the policy must be provided to all new employees at the inception of their employment. The ordinance is enforced by the City of Houston, Department of Health & Human Services Bureau of Occupational Health. Concerns or complaints should be directed to that office. We anticipate and appreciate your cooperation in complying with the new ordinance. 12 BPMC.Lease Form.TX.March 2013 Tenant Initials

C Tenant Representation Letter Information about Brokerage Services Before working with a real estate broker, you should know that the duties of a broker depend on whom the broker represents. If you are a prospective seller or landlord (owner) or a prospective buyer or tenant (buyer), you should know that the broker who lists the property for sale or lease is the owner’s agent. A broker who acts as a subagent represents the owner in cooperation with the listing broker. A broker who acts as a buyer’s agent represents the buyer. A broker may act as an intermediary between the parties if the parties consent in writing. A broker can assist you in locating a property, preparing a contract or lease, or obtaining financing without representing you. A broker is obligated by law to treat you honestly. IF THE BROKER REPRESENTS THE OWNER: The broker becomes the owner’s agent by entering into an agreement with the owner, usually through a written listing agreement, or by agreeing to act as a subagent by accepting an offer of sub agency from the listing broker . A subagent may work in a different real estate office . A listing broker or subagent can assist the buyer but does not represent the buyer and must place the interests of the owner first . The buyer should not tell the owner’s agent anything the buyer would not want the owner to know because an owner’s agent must disclose to the owner any material information known to the agent . IF THE BROKER REPRESENTS THE BUYER: The broker becomes the buyer’s agent by entering into an agreement to represent the buyer, usually through a written buyer representation agreement. A buyer’s agent can assist the owner but does not represent the owner and must place the interests of the buyer first. The owner should not tell a buyer’s agent anything the owner would not want the buyer to know because a buyer’s agent must disclose to the buyer any material information known to the agent. IF THE BROKER ACTS AS AN INTERMEDIARY: A broker may act as an intermediary between the parties if the broker complies with The Texas Real Estate License Act. The broker must obtain the written consent of each party to the transaction to act as an intermediary. The written consent must state who will pay the broker and, in conspicuous bold or underlined print, set forth the broker’s obligations as an intermediary. The broker is required to treat each party honestly and fairly and to comply with The Texas Real Estate License Act. A broker who acts as an intermediary in a transaction: (1) shall treat all parties honestly; (2) may not disclose that the owner will accept a price less than the asking price unless authorized in writing to do so by the owner; (3) may not disclose that the buyer will pay a price greater than the price submitted in a written offer unless authorized in writing to do so by the buyer; and (4) may not disclose any confidential information or any information that a party specifically instructs the broker in writing not to disclose unless authorized in writing to disclose the information or required to do so by The Texas Real Estate License Act or a court order or if the information materially relates to the condition of the property. With the parties’ consent, a broker acting as an intermediary between the parties may appoint a person who is licensed under The Texas Real Estate License Act and associated with the broker to communicate with and carry out instructions of one party and another person who is licensed under that Act and associated with the broker to communicate with and carry out instructions of the other party. If you choose to have a broker represent you, you should enter into a written agreement with the broker that clearly establishes the broker’s obligations and your obligations. The agreement should state how and by whom the broker will be paid. You have the right to choose the type of representation, if any, you wish to receive. Your payment of a fee to a broker does not necessarily establish that the broker represents you. If you have any questions regarding the duties and responsibilities of the broker, you should resolve those questions before proceeding.
