10. Service Level

10.1. Service Level Agreement. SUMOTEXT provides a Service Level Agreement (“SLA”) of 99.9%, meaning that the SUMOTEXT systems will be available for transmission and reception of messages and Transactions from the Client 99.9% of the time in a given Processing Period, excluding scheduled maintenance. Scheduled maintenance and associated downtime shall not exceed 8 hours on a monthly basis and will always be conducted with at least 24 hours notice to Client.  Every reasonable effort will be made to schedule maintenance during off-peak hours.

10.2 Measurement of SUMOTEXT performance under the SLA is determined by the availability and correct functioning of SUMOTEXT service infrastructure including the software and systems necessary for receiving and correctly routing messages and Transactions, and the associated electrical power, routers, switches, hubs, cabling, HVAC, and server hardware for those systems.  Measurement of SUMOTEXT performance under the SLA does not include the availability or the correct functioning of a) the SMS or internet worldwide infrastructure beyond SUMOTEXT’s control; b) Operator infrastructure; c) Client’s infrastructure including network connectivity, hardware, or software; or d) end user mobile devices.  SUMOTEXT network downtime (“SUMOTEXT Downtime”) exists from the time a Client files a trouble ticket with SUMOTEXT notifying SUMOTEXT that SUMOTEXT systems are unable to receive and correctly route messages and Transactions until the time the SUMOTEXT systems are once again receiving and correctly routing messages and Transactions.  However, if Clients exceeds traffic levels specified in section 9.12 without providing the required notice to SUMOTEXT as required in 9.12, any outages or processing in such traffic periods shall be excluded from the calculation of SUMOTEXT Downtime. Downtime is monitored and measured by SUMOTEXT.  In addition, the Client may open a trouble ticket with SUMOTEXT at any time if transmissions or Transactions are failing.

10.3 SLA Performance Rebates. In the event that SUMOTEXT fails to meet its SLA as specified in 10.1, and such failure is solely attributable to SUMOTEXT, SUMOTEXT will refund such Client ten (10%) percent of the Monthly SUMOTEXT Service Fee, as specified in Section 2 of this Agreement, for each sixty (60) minute interval of SUMOTEXT Downtime below the minimum specified in 10.1 above, up to, and not to exceed 100% of the Client’s Monthly SUMOTEXT Service Fee in any Processing Period.

11. GENERAL

11.1 Confidentiality. Each party (the “Receiving Party”) undertakes to retain in confidence the terms of this Agreement and all other non-public information, technology, materials and know-how of the other party disclosed or acquired by the Receiving Party pursuant to or in connection with this Agreement which is either designated as proprietary and/or confidential or, by the nature of the circumstances surrounding disclosure, ought in good faith to be treated as proprietary and/or confidential (“Confidential Information”); provided that each party may disclose the terms and conditions of this Agreement to its immediate legal and financial consultants in the ordinary course of its business. Notwithstanding anything to the contrary, Client understands and consents that Client metrics and statistics are provided to SUMOTEXT Operators as part of SUMOTEXT’s partnerships to process Transactions with such Operators. Neither party shall use any Confidential Information with respect to which it is the Receiving Party for any purpose other than to carry out the activities contemplated by this Agreement. Each party agrees to use commercially reasonable efforts to protect Confidential Information of the other party, and in any event, to take precautions at least as great as those taken to protect its own confidential information of a similar nature. Each party shall also notify the other promptly in writing in the event such party learns of any unauthorized use or disclosure of any Confidential Information that it has received from the other party, and will cooperate in good faith to remedy such occurrence to the extent reasonably possible. The restrictions set forth in this paragraph shall not apply to any information that: (i) was known by the Receiving Party without obligation of confidentiality prior to disclosure thereof by the other party; (ii) was in or entered the public domain through no fault of the Receiving Party; (iii) is disclosed to the Receiving Party by a third party legally entitled to make such disclosure without violation of any obligation of confidentiality; (iv) is required to be disclosed by applicable laws or regulations (but in such event, only to the extent required to be disclosed); or (v) is independently developed by the Receiving Party without reference to any Confidential Information of the other party. Upon request of the other party, each party shall return to the other all materials, in any medium, which contain or reveal all or any part of any Confidential Information of the other party.  Each party acknowledges that breach of this by such party would result in irreparable harm to the other party, for which money damages would be an insufficient remedy, and therefore that the other party shall be entitled to seek injunctive relief to enforce the provisions of this Section 11.1.

11.2 Representations, Warranties and Covenants. Each party hereby represents, warrants and covenants that: (i) it has the full right, power, legal capacity and authority to enter into this Agreement and to carry out the terms and conditions hereof without causing a conflict with its obligations to third parties; (ii) it owns or has obtained all rights sufficient to fully perform its obligations hereunder; and that the rights granted herein are, free and clear of any lien, mortgage, restriction, encumbrance in favor of any person or entity not a party hereto or known third party claims for infringement of any third party’s Intellectual Property Rights, breach of contract rights or other interest; and  (iii) it shall comply with all applicable laws, rules and regulations in the provision of the Services.

11.3 Warranty; Disclaimer. SUMOTEXT represents and warrants that the Services shall conform, in all material respects, to the applicable documentation provided by SUMOTEXT to Client.

The Services and any other services provided by any Operator, which are provided by means of the Internet, are provided “as is”, “where is” and “when available”. SUMOTEXT is responsible only for providing data transmission to effect certain routing of messages and Transactions from Client to the Aggregator and is not responsible for the Aggregator’s actions and/or ability to effectuate Client’s requests. SUMOTEXT is therefore not responsible for the availability of any Operator, or the availability and/or performance of the Internet. SUMOTEXT is also not responsible for any damages or costs Client suffers or incurs as a result of any instructions given, actions taken or omissions made by Client. IN NO EVENT WILL SUMOTEXT’S LIABILITY ARISING OUT OF THIS AGREEMENT EXCEED THE FEES PAID TO SUMOTEXT BY CLIENT DURING THE THREE (3) MONTH PERIOD IMMEDIATELY PRECEDING THE EVENT WHICH GAVE RISE TO OPPORTUNITY OR PROFITS, COSTS OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICES, OR FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR SPECIAL DAMAGES ARISING OUT OF OR RELATED TO THIS AGREEMENT, UNDER ANY CAUSE OF ACTION OR THEORY OF LIABILITY (INCLUDING NEGLIGENCE), AND WHETHER OR NOT SUMOTEXT HAS ADVISED CLIENT OR ANY THIRD PARTY OF THE POSSIBILITY OF SUCH DAMAGE. THESE LIMITATIONS WILL APPLY NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY. Notwithstanding the above, the limitations set forth above shall be enforceable to the maximum extent allowed by applicable law.

11.5 Indemnification. Client will indemnify, defend and hold harmless SUMOTEXT, its past, present, and future officers, directors, agents and employees, from and against any and all claims, losses, demands, liabilities, damages, penalties, costs and expenses (including reasonable attorneys’ fees), either arising out of or relating to (i) the breach of this Agreement by Client, (ii) the sale or use of any product or Services sold by Client, (iii) claims brought or damages suffered by any Operator, SUMOTEXT, SUMOTEXT’s customers, or prospective customers of SUMOTEXT relating to Client’s or its agents’ misuse and/or abuse of the Services, except to the extent solely caused by SUMOTEXT or (iv) claims brought or damages suffered by any Operator or third-party, or penalties assessed on SUMOTEXT by any Operator as a result of Client’s breach, act, omission or otherwise violation of section 10. 

SUMOTEXT will indemnify, defend and hold harmless Client, its past, present, and future officers, directors, agents and employees, from and against any damages (including reasonable attorney’s fees) arising out of (a) SUMOTEXT’s breach of this Agreement, or (b) a third party claim that the SUMOTEXT software, website, or services infringe a United States patent, copyright or trade secret right of a third party. Client’s sole remedies for a claim of infringement or misappropriation of any intellectual property shall be SUMOTEXT’s replacement of the offending software or services, SUMOTEXT’s obtaining a license for Client’s continued use of the software or services, or SUMOTEXT’s termination of the affected licenses granted hereunder. The indemnification obligations set forth in this Section are contingent upon (a) the indemnified party giving prompt written notice to the indemnifying party of a claim for which the indemnified party is seeking indemnification, (b) the indemnified party allowing the indemnifying party to control the defense and related settlement negotiations for any such claim, and (c) the indemnified party fully assisting and cooperating in the defense so long as the indemnifying party pays the indemnified party’s out-of-pocket expenses.

11.6. Severability. In the event that any provision of this Agreement is unenforceable or invalid such unenforceability or invalidity will not render this Agreement unenforceable or invalid as a whole, and in such event, such provision will be changed and interpreted so as to best accomplish the objectives of such unenforceable or invalid provision within the limits of applicable law or applicable court decisions.

11.7 Notice. Except as otherwise provided for in the Agreement, any notice or demand, with respect to this Agreement shall be in writing and shall be effective on the date received only if it is sent by a courier service that confirms delivery in writing, or if sent by certified or registered mail, postage prepaid, return receipt requested, addressed, if to SUMOTEXT, Inc., then to “Attention Director of Business Operations” at SUMOTEXT, Inc. 2100 Riverdale, Suite 200, Little Rock, AR, 72202 and if to Client, then to the address provided in Section 1 of this Agreement.

11.9 Governing Law and Mediation. This Agreement shall be governed by the laws of the State of Arkansas without reference to its principles of conflicts of laws.  Any claim arising out or relating to this Agreement not resolved by good faith negotiations shall be resolved exclusively by arbitration conducted in Arkansas by a sole arbitrator (“Arbitrator”) in accordance with the rules of the American Arbitration Association (“AAA”) and shall be appointed by agreement of the parties; if the parties fail to agree upon the Arbitrator within thirty (30) days of notice of arbitration provided by either party, the AAA shall appoint the Arbitrator.

Judgment on the award or any other final or interim decision rendered by the Arbitrator may be entered, registered or filed for enforcement in any court having jurisdiction thereof.

11.10 Independent Contractors. Each party hereto is acting as an independent contractor and not as an agent, partner, employer, employee, or joint venture of the other.
