Dear John:

SFN Professional Services LLC d/b/a Tatum (“Tatum,” “we,” “us” or “our”) is pleased that Goodman Networks (“Company,” “you” or “your”) has selected us to provide you with outsourced interim services. The services (the “Services”) and fees will be more particularly described on the Schedule attached hereto and will be provided by the individual resource (the “Tatum Resource”) identified on such Schedule. Schedules for additional or different Tatum Resources may be added from time to time upon the mutual written agreement of the parties. In addition, upon the request of the Company and the execution of an additional Schedule to this agreement, Tatum will provide search Services to the Company, all as more particularly described on such Schedule.

Engagement. The Tatum Resource will be one of Tatum’s professionals, and we will be solely responsible for determining the conditions, terms and payment of compensation and benefits for the Tatum Resource. You will be solely responsible for providing the Tatum Resource day-to-day guidance, supervision, direction, assistance and other information necessary for the successful and timely completion of the Services. Tatum will have no oversight, control, or authority over the Tatum Resource with respect to the Services. The Company acknowledges that it is solely responsible for the sufficiency of the Services for its purposes. The Company will designate a management-level individual to be responsible for overseeing the Services, and the Tatum Resource will report directly to such individual with respect to the provision of the Services. Unless the Tatum Resource is acting as an executive officer of the Company and is authorized by the Company to make such decision, the Company will not permit or require the Tatum Resource to be the ultimate decision making authority for any material decision relating to your business, including, without limitation, any proposed merger, acquisition, recapitalization, financial strategy or restructuring.

Fees and Expenses. You will pay us the fees set forth on the applicable Schedule. In addition to our standard professional service fees, we will charge an administrative fee equal to 6% of our professional service fees to cover otherwise unbilled items difficult to estimate such as telephone charges, computer use, in-house copying, facsimiles, and other internal services. In addition, you will reimburse Tatum directly for all travel and out-of-pocket expenses incurred in connection with this agreement (including any Schedules).

Payment Terms. Payments to Tatum should be made upon receipt of invoice by electronic transfer in accordance with the instructions set forth below or such alternative instructions as provided by us from time to time. Any amounts not paid when due may be subject to a periodic service charge equal to the lesser of 1.5% per month and the maximum amount allowed under applicable law, until such amounts are paid in full, including assessed service charges. In lieu of terminating this agreement, we may suspend the provision of any Services if amounts owed are not paid in accordance with the terms of this agreement.

Hiring the Tatum Resource Outside of a Tatum Agreement. If, at any time during the time frame in which a Tatum Resource is providing Services to the Company and for a period of 12-months thereafter, other than in connection with this agreement or another Tatum agreement, the Company or any of its subsidiaries or affiliates employs such Tatum Resource, or engages such Tatum Resource as an independent contractor, the Company will pay Tatum a placement fee in an amount equal to 30% of the Annualized Compensation (as defined below). “Annualized Compensation” is defined as salary, incentive, signing and other bonuses, equity compensation, and any other compensation that may be earned by the Tatum Resource during the first 12 months of service with the Company (or its subsidiary or affiliate) regardless of when or if such compensation is actually paid. The placement fee shall be due upon the commencement of the Tatum Resource’s employment or engagement with the Company (or its subsidiary or affiliate).

Warranties and Disclaimers. We disclaim all representations and warranties, whether express, implied or statutory, including, but not limited to any warranties of quality, performance, merchantability, or fitness of use or purpose. Without limiting the foregoing, we make no representation or warranty with respect to the Tatum Resource or the Services provided hereunder, and we will not be responsible for any action taken by you in following or declining to follow any of the Tatum Resource’s advice or recommendations. The Services provided by Tatum and the Tatum Resource hereunder are for the sole benefit of the Company and not any unnamed third parties. The Services will not constitute an audit, review, opinion, or compilation, or any other type of financial statement reporting or attestation engagement that is subject to the rules of the AICPA or other similar state or national professional bodies or laws and will not result in an opinion or any form of assurance on internal controls.

Limitation of Liability; Indemnity.

(a) Tatum’s liability in any and all categories and for any and all causes arising under this agreement, whether based in contract, tort, negligence, strict liability or otherwise, will, in the aggregate, not exceed the actual fees paid by you to us over the previous two months’ of the agreement with respect to the Tatum Resource from whom the liability arises. In no event will we be liable for incidental, consequential, punitive, indirect or special damages, including, without limitation, interruption or loss of business, profit or goodwill. As a condition for recovery of any liability, you must assert any claim against us within three months after discovery or 60 days after the termination or expiration of the applicable Schedule under which the liability arises, whichever is earlier.

(b) You agree to indemnify us and the Tatum Resource to the full extent permitted by law for any losses, costs, damages, and expenses (including reasonable attorneys’ fees), as they are incurred, in connection with any cause of action, suit, or other proceeding arising in connection with the Tatum Resource’s services to you.

Insurance. To the extent the Company has directors’ and officers’ liability insurance in effect, the Company will provide such insurance coverage for any Tatum Resource serving as an officer or executive of the Company under this agreement at no additional cost to the Tatum Resource, along with written evidence to Tatum or the Tatum Resource that the Tatum Resource is covered by such insurance. Furthermore, the Company will maintain such insurance coverage with respect to occurrences arising during the term of this agreement for at least three years following the termination or expiration of the applicable Schedule or will purchase a directors’ and officers’ extended reporting period or “tail” policy to cover the Tatum Resource for such three year period.

Change in Company Circumstances. In the event that the Company’s financial condition or liquidity significantly deteriorates or the Company enters into discussions with restructuring or bankruptcy advisors, Tatum and the Company will review the current fee structure and payment terms under this agreement (including any Schedule) and agree on appropriate modifications. In addition, Tatum and the Company will discuss the need for additional Tatum resources with specialized skills in working with companies undergoing significant debt and equity restructuring, and as needed, Tatum resources with experience helping companies seeking or operating under bankruptcy protection. The agreed upon additional resources will be engaged under terms and fees commensurate to the expertise and services to be provided. In the event that Tatum and the Company cannot agree on appropriate modifications to this agreement (including any Schedule) or the need for additional Tatum resources, Tatum, or the Company may immediately terminate this agreement or any Schedule upon notice to the Company.

Governing Law. Arbitration and Witness Fees.

(a) This agreement will be governed by and construed in accordance with the laws of the State of Texas, without regard to conflicts of laws provisions.

(b) If the parties are unable to resolve any dispute arising out of or in connection with this agreement, the parties agree and stipulate that any such disputes will be settled by binding arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association (“AAA”). The arbitration will be conducted in the Dallas, Texas office of the AAA by a single arbitrator selected by the parties according to the rules of the AAA, and the decision of the arbitrator will be final and binding on both parties. In the event that the parties fail to agree on the selection of the arbitrator within 30 days after either party’s request for arbitration under this Section, the arbitrator will be chosen by the AAA. The arbitrator may in his or her discretion order documentary discovery but will not allow depositions without a showing of compelling need. The arbitrator will render his or her decision within 90 days after the call for arbitration. Judgment on the award of the arbitrator may be entered in and enforced by any court of competent jurisdiction. The arbitrator will have no authority to award damages in excess or in contravention of this agreement and may not amend or disregard any provision of this agreement, including this section. Notwithstanding the foregoing, either party may seek appropriate injunctive relief from any court of competent jurisdiction, and Tatum may pursue payment of any unpaid amounts due under this agreement through any court of competent jurisdiction.

(c) In the event any professional of Tatum (including, without limitation, any Tatum Resource) is requested or authorized by you or is required by government regulation, subpoena, or other legal process to produce documents or appear as witnesses in connection with any action, suit or other proceeding initiated by a third party against you or by you against a third party, you will, so long as Tatum is not a party to the proceeding in which the information is sought, reimburse Tatum for its professional’s time (based on customary rates) and expenses, as well as the fees and expenses of its counsel, incurred in responding to such requests. This provision is in addition to and not in lieu of any indemnification obligations the Company may have under this agreement.

Miscellaneous.

(a) This agreement together with all Schedules constitutes the entire agreement between the parties with regard to the subject matter hereof and supersedes any and all agreements, whether oral or written, between the parties with respect to its subject matter. No amendment or modification to this agreement will be valid unless in writing and signed by both parties.

(b) If any portion of this agreement is found to be invalid or unenforceable, such provision will be deemed severable from the remainder of this agreement and will not cause the invalidity or unenforceability of the remainder of this agreement, except to the extent that the severed provision deprives either party of a substantial portion of its bargain.

(c) Neither party will be deemed to have waived any rights or remedies accruing under this agreement unless such waiver is in writing and signed by the party electing to waive the right or remedy. The waiver by any party of a breach or violation of any provision of this agreement will not operate or be construed as a waiver of any subsequent breach of such provision or any other provision of this agreement.

(d) Neither party will be liable for any delay or failure to perform under this agreement (other than with respect to payment obligations) to the extent such delay or failure is a result of an act of God, war, earthquake, civil disobedience, court order, labor dispute, or other cause beyond such party’s reasonable control.

(e) You may not assign your rights or obligations under this agreement without the express written consent of Tatum. Nothing in this agreement will confer any rights upon any person or entity other than the parties hereto and their respective successors and permitted assigns and the Tatum Resources.

(f) The expiration or termination of this agreement or any Schedule will not destroy or diminish the binding force and effect of any of the provisions of this agreement or any Schedule that expressly, or by reasonable implication, come into or continue in effect on or after such expiration or termination, including, without limitation, provisions relating to payment of fees and expenses (including witness fees and expenses and liquidated damage fees), governing law, arbitration, limitation of liability and indemnity.

(g) You agree to reimburse Tatum for all costs and expenses (including, without limitation, reasonable attorneys’ fees, court costs and arbitration fees) incurred by Tatum in enforcing collection of any monies due under this agreement.

(h) You agree to allow us to use the Company’s logo and name on Tatum’s website and other marketing materials for the sole purpose of identifying the Company as a client of Tatum. Tatum will not use the Company’s logo or name in any press release or general circulation advertisement without the Company’s prior written consent.
