RECITALS

WHEREAS, the Company wishes to engage FPC for various consulting services based on the terms set forth herein; and

WHEREAS, FPC is in the business of providing, and wishes to provide, such services.

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and the mutual promises and covenants contained herein, the parties agree as follows:

1.1       Services. FPC shall perform, or cause to be performed, the following operational consulting services (the “Services”) for the Company or its Affiliates, which may include the following, without limitation.

“Affiliate” of an entity means any other entity (whether domestic or foreign) which, directly or indirectly, controls, is controlled by or is under common control with such entity, where control means the ability to direct the affairs of an entity through ownership of voting interest, contract rights or otherwise.

1.2       Changes in Scope or Additional Services. Company may request that FPC perform additional services for Company. Within a reasonable period (not to exceed fifteen (15) business days) after receiving such a request from Company, FPC shall prepare and submit a written proposal that: (i) defines and describes how FPC would fulfill or satisfy such request, and describes any additional services to be provided by FPC in reasonable detail; (ii) sets forth pricing and specifications anticipated by FPC in connection with fulfilling such request; and (iii) sets forth any other information FPC considers appropriate for inclusion. No additional services shall be binding upon Company or FPC unless executed and delivered by an authorized signatory of such party. A “business day” means any week day other than a day designated as a holiday.

1.3       Personnel. FPC shall staff its project team with qualified professionals. FPC shall maintain staffing levels as necessary to properly perform FPC’s obligations under this Agreement. FPC may utilize subcontractors in the performance of the Services; however, if Company determines that the performance or conduct of any subcontractor is unsatisfactory, Company may notify FPC of its determination in writing, indicating the reasons therefor, in which event FPC shall promptly take all necessary actions to remedy the performance or conduct of such subcontractor and, if so requested by the Company, to replace such subcontractor.

2

1.4       Project Management. The Company and FPC shall consult with each other with regard to project management and decision making related to the Services.

2.1       Total Fee. The total consideration payable to FPC in consideration of the Services to be performed under this Agreement is $500,000 (the “Service Fee”). Company shall reimburse FPC for reasonable out of pocket expenses incurred by FPC in providing Services including, without limitation, costs of travel.

2.2       Invoicing and Payment. FPC shall invoice the Company on May 15, 2016 for 50% of the Service Fee and August 15, 2016 for 50% of the Service Fee. FPC shall invoice the Company quarterly in arrears for expense reimbursements permitted hereunder. Each expense reimbursement invoice rendered by FPC shall include a reasonably detailed summary of the expenses reflected therein. The Company shall promptly pay each invoice issued by FPC hereunder within fifteen (15) calendar days after its receipt.

2.3       Discretionary Refund. Prior to the end of the Term, FPC may, in its sole discretion, refund a portion of fees received hereunder to the Company. Such refund is intended to ensure FPC’s aggregate revenue meets the costs associated with providing services.

2.4       Taxes. The Company shall pay any and all applicable taxes, however designated, incurred as a result of or otherwise in connection with this Agreement or the Services, excluding taxes based upon or measured by the net income of FPC.

3.     Work Product and Proprietary Materials. All work product and general knowledge owned by FPC or created or acquired thereafter (collectively, “FPC Work Product”), shall continue to be owned exclusively by FPC and Company shall not have any rights thereto except as provided herein. To the extent any FPC Work Product is used or embodied in the performance of the Services or otherwise delivered to Company hereunder, FPC grants Company and its Affiliates a worldwide, perpetual, non- transferable, royalty-free license to use such FPC Work Product for Company’s internal purposes during the Term of this Agreement.

4.1       Protection of Confidential Information. During the Term and except as permitted herein, neither party shall disclose to any non-Affiliated third party, and each party shall keep strictly confidential, all Confidential Information of the other party. Each party receiving any such Confidential Information of the other (a “Receiving Party”) may, however, disclose any portion of the Confidential Information of the other party (the “Disclosing Party”) to such officers, directors, partners, principals, employees, affiliates (but only to the extent such affiliates receive confidential information), advisors (including legal advisors, consultants, accountants and financial advisors), and authorized independent contractors or agents (collectively, “Representatives”) of the Receiving Party as are engaged to assist in providing the Services contemplated by this Agreement and have a need to know such portion, provided that Representatives: (i) are directed to treat such Confidential Information confidentially and not to use such Confidential Information other than as permitted by hereby, and (ii) are subject to a fiduciary, contractual or other duty to maintain the confidentiality thereof. The Receiving Party shall be responsible for any improper use or disclosure of any of the Disclosing Party’s Confidential Information by any of the Receiving Party’s Representatives.

4.2       Definition. “Confidential Information” means information, whether provided or retained in writing, verbally, by electronic or other data transmission or in any other form or media whatsoever or obtained through on-site visits at Company or FPC facilities that is confidential, proprietary or otherwise not generally available to the public including, without limitation, trade secrets, marketing and sales information, product information, technical information and technology, Company and FPC information, information about trade techniques and other processes and procedures, financial information and business information, plans and prospects.

4.3       Exceptions. The obligations of this Article 4 shall not apply to: (i) any Confidential Information for a period longer than it is legally permissible to restrict disclosure of that item of Confidential Information; or (ii) any Confidential Information that the Receiving Party can demonstrate was:

4.4       Required Disclosure. Either party may disclose Confidential Information of the other to the extent required by law or by order of a court or governmental agency; provided, however, that, except to the extent prohibited by law or pursuant to an ordinary course examination by a regulator, bank examiner or self-regulatory organization, not specifically directed at the Disclosing Party or the Confidential Information, the Receiving Party shall give the Disclosing Party (as the owner of such Confidential Information) prompt notice, and shall use its reasonable efforts to cooperate with the Disclosing Party (at its cost), if the Disclosing Party wishes to obtain a protective order or otherwise protect its rights and interests in and to such Confidential Information and the confidentiality thereof.

5.3       Limitation of Liability. Neither FPC nor its Representatives shall be liable to the Company or any of its Affiliates for any loss, liability, damage or expense arising out of or in connection with the performance of Services contemplated by this Agreement, unless such loss, liability, damage or expense shall be proven to result directly from gross negligence or willful misconduct on the part of FPC or its Representatives acting within the scope of such person’s employment or authority. Except as FPC may otherwise agree in writing after the date hereof (i) FPC and its Representatives shall have the right to, and shall have no duty (contractual or otherwise) not to, directly or indirectly do business with any client or customer of any of the Company or any of its Affiliates, (ii) neither FPC nor its Representatives shall be liable to the Company or any of its Affiliates for breach of any duty (contractual or otherwise) by reason of any such activities of or of such person’s participation therein, and (iii) in the event that FPC or its Representatives acquire knowledge of a potential transaction or matter that may be a corporate opportunity for the Company or any of its Affiliates, on the one hand, and FPC or its Representatives, on the other hand, or any other person, FPC and its Representatives shall have no duty (contractual or otherwise) to communicate or present such corporate opportunity to the Company or any of its Affiliates and, notwithstanding any provision of this Agreement to the contrary, shall not be liable to the Company or any of its Affiliates for breach of any duty (contractual or otherwise) by reasons of the fact that the FPC or its Representatives directly or

5

indirectly pursues or acquires such opportunity for itself, directs such opportunity to another person, or does not present such opportunity to the Company or any of its Affiliates. In no event will any of the parties hereto be liable to any other party hereto for any indirect, special, incidental or consequential damages, including lost profits or savings, whether or not such damages are foreseeable, or in respect of any liabilities relating to any third party claims (whether based in contract, tort or otherwise) other than the Claims (as defined in Section 7) relating to the Services to be provided hereunder.

6.1       Dispute Resolution Procedure. Any dispute between the parties as to either the interpretation of any provision of this Agreement or the performance by FPC or Company hereunder shall be resolved as specified in this Section 6.1.

a.     Upon the written request of either party, each of the parties shall appoint a designated representative who, in the case of Company, shall be a Vice President (or more senior corporate officer), to meet for the purpose of endeavoring to resolve such dispute.

b.     Such representatives shall discuss the problem and negotiate in good faith in an effort to resolve the dispute promptly and without the necessity of any formal proceeding relating thereto.

c.     If any dispute arises between the parties, and the disputed matter has not been resolved by the designated representatives within fifteen (15) business days after such dispute has come to their attention, or such longer period as agreed to in writing by the parties, each party shall, subject to Section 9.8, have the right to commence any legal proceeding as permitted by law.

6.2       Agreements in Writing. No agreement achieved under this dispute resolution process shall be binding on either party unless set forth in a writing executed by the parties hereto.

6.3       No Termination or Suspension of Services. Notwithstanding anything to the contrary contained herein, and even if any dispute arises between the parties, in no event shall FPC interrupt or delay the provision of Services to the Company, or perform any other action that prevents, slows down, or reduces in any way the provision of Services or the Company’s ability to conduct its business, unless: (i) authority to do so is granted by the Company in writing or conferred by a court of competent jurisdiction; or (ii) this Agreement has been terminated pursuant to Article 8 (and then FPC may take any such action only if and to the extent permitted thereby).

6.4       Injunctive relief. Neither party shall be obligated to follow the procedures set forth in Section 6.1 in order to seek injunctive relief for violations of Article 3 or Article 4.

7.     Indemnification. The Company shall defend, indemnify and hold harmless FPC and its Representatives (collectively, the “Indemnitees”) from and against any and all loss, liability, damage or expenses arising from any claim by any person with respect to, or in any way related to, the performance of Services contemplated by this Agreement (including attorneys’ fees) (collectively, “Claims”) resulting from any act or omission of any of the Indemnitees, other than for Claims which have been proven to be the direct result of gross negligence or willful misconduct by an Indemnitee. The Company shall defend at its own cost and expense any and all suits or actions (just or unjust) which may be brought against the Company or any of its Affiliates or any of the Indemnitees or in which any of the Indemnitees may be impleaded with others upon any Claims, or upon any matter, directly or indirectly, related to or arising out of this Agreement or the performance hereof by any of the Indemnitees, except that if such damage shall be proven to be the direct result of gross negligence or willful misconduct by an Indemnitee, then FPC shall reimburse the Company for the costs of defense and other costs incurred by the Company.
