(a)Responsibilities of the Client

1)The Client shall cooperate with Provider in connection with the performance of the Services, including, without limitation, providing Provider with reasonable facilities and timely access to data, information and personnel of Client. The Client shall be responsible for the performance of its personnel and third parties retained by the Client, for the timeliness, accuracy and completeness of

all data and information (including all financial information and statements) provided to Provider by or on behalf of Client and for the implementation of any Advice provided as part of the Services. Provider may use and rely on information and data furnished by the Client or others without verification. The performance of the Services is dependent upon the timely performance of the Client’s responsibilities under the Contract and timely decisions and approvals of the Client in connection with the Services. Provider shall be entitled to rely on all decisions and approvals of the Client.

2)The Client shall be solely responsible for, among other things: (A) making all management decisions and performing all management functions (even if relying solely on Advice provided under the Services), (B) designating one or more individuals who possess suitable skill, knowledge, and/or experience, preferably within senior management to oversee and/or approve the Services, (C) evaluating the adequacy and results of the Services, (D) accepting responsibility for implementing the results of the Services, and (E) establishing and maintaining internal controls, including, without limitation, monitoring ongoing activities. The provisions in the preceding sentence are not intended to and do not alter, modify or change in any manner the duties and obligations of Provider as agreed to and set forth in this Contract. With respect to the data and information provided by the Client to Provider for the performance of the Services, Provider is entitled to assume that the Client has all rights required to provide such data and information.

(b)Responsibilities of Provider

(i)Any Services provided by or on behalf of Provider will be based upon regulations (including regulations under the Securities and Exchange Commission) and generally accepted accounting principles in the United States (“GAAP”) in effect at the time the Services are provided. Subsequent changes in or to the foregoing (for which Provider shall have no responsibility to advise the Client) may result in the Services provided by or on behalf of Provider being rendered invalid.

(ii)Except as specifically agreed to in writing, Provider shall not assume any responsibility for any financial reporting with respect to the Services. Provider shall have no responsibility to address any legal matters or questions of law.

(iii)In formulating any Advice as part of the Services, Provider may discuss ideas with the Client orally or show the Client drafts of such Advice. To the extent that the content of drafts or oral Advice are

expected to be finalized and confirmed to the Client in writing, such confirmed Advice shall supersede any previous drafts or oral Advice. Provider shall not be responsible if the Client or others choose to rely on, act or refrain from acting on the basis of any drafts or oral Advice.

(iv)Provider will use its reasonable endeavors, acting in a commercially appropriate manner, to carry out the Services in accordance with any timetable specified in the Contract. However, it is agreed that any dates specified in the Contract for the performance of any part of the Services, including delivery of any Advice, are estimated dates for planning purposes only. Provider will notify the Client promptly if it expects or encounters any significant delays which will materially affect achievement of any timetable for delivery of the Services.

(v)Unless expressly agreed otherwise in writing, each item of Advice will be deemed accepted (and the Services or relevant part completed) when such Advice has been delivered in its final form and no material objection to the Advice or its content is notified by the Client to Provider in writing within 10 days of delivery or when first use of the Advice is made by or on behalf of the Client, whichever occurs first.

(vi)For the performance of the Engagement, Provider is obliged to comply with applicable regulations and its own internal policies of Anti Money Laundering and Financing of Terrorism, for which it may require to the Client information and documentation.

2.2Provider’s invoices are due and payable by the Client within 30 days of presentation.

The Client shall be responsible for all taxes, such as VAT, sales and use tax, gross receipts tax, withholding tax, and any similar tax, imposed on or in connection with the Services, other than Provider’s income and property taxes. It is intended that the provisions of this Contract comply with Section 409A of the Internal Revenue Code, and applicable administrative guidance and regulations (“Section 409A”), and all provisions of this Contract shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes and penalties under Section 409A and that all reimbursements provided under this Contract shall be made or provided in accordance with Section 409A. Notwithstanding the foregoing, Client makes no representations or warranties and shall have no responsibility regarding the tax implications of the compensation and benefits to be paid to Provider under this Contract, including under Section 409A.

(c)Upon termination of the Contract for any reason, the Client will compensate Provider in accordance with the terms of the Contract for the Services performed and expenses incurred up to the effective date of termination.

(d)Termination of any part of the Contract (including a specific SOW) shall not affect the remainder of the Contract (including other relevant SOWs included in the Contract).

(a)To the extent that, in connection with the Contract, Provider comes into possession of any information related to the Services, trade secrets or other proprietary information relating to the Client which is either designated by the disclosing party as

confidential or is by its nature clearly confidential (“Confidential Information”), Provider shall not disclose such Confidential Information to any third party unless directed to by the Client or unless required by law, regulation, judicial or administrative process, or in accordance with applicable professional standards, or in connection with potential or actual mediation, arbitration or litigation.

(i)is or becomes publicly available (including, without limitation, any information filed with any governmental agency and available to the public) other than as the result of the default of Provider,

(ii)becomes available to Provider on a non-confidential basis from a source other than the Client which Provider reasonably believes is not prohibited from disclosing such Confidential Information to Provider by an obligation of confidentiality to the Client,

(iii)is known by Provider prior to its receipt from the Client without any obligation of confidentiality, or

(iv)is developed by Provider independently of the Confidential Information disclosed by the Client.

(c)The Client shall not disclose to any third party any Advice without the express written consent of Provider, except

(v)disclosure may be made to the extent mandatory laws, applicable regulations, rules and professional obligations prohibit limitations on disclosure, structure associated with the Services or transactions described in the Contract and the Client acknowledges that none of its other advisers has imposed or will impose restrictions or limitations with such tax treatment or tax structure,

(vi)to the extent legislation or regulations of any jurisdiction provide for the reporting of such Advice, and

(vii)to Client’s auditors in their capacity as such.

(d)All Services are intended only for the benefit of the Client identified in the Contract. The mere receipt of any Advice (or any information derived therefrom) by any other persons is not intended to create any duty of care, professional relationship or any present or future liability of any kind between those persons and Provider.

(a)Neither party may assign or otherwise transfer the Contract. Neither party will directly or indirectly agree to assign or transfer to a third party any Claim against the other party arising out of the Contract.

(a)Except as instructed otherwise in writing, Provider and the Client are authorized to use properly addressed, email (including emails exchanged via internet media) and voicemail communication for both sensitive and non-sensitive documents and other communications concerning the Contract, as well as other means of communication used or accepted by the other.

(b)It is recognized that the internet is inherently insecure and that data can become corrupted, communications are not always delivered promptly (or at all) and that other methods of communication may be appropriate. Electronic communications are also prone to contamination by viruses. Each party will be responsible for protecting its own systems and interests and, to the fullest extent permitted by law, will not be responsible to the other on any basis (contract, tort, including without limitation negligence, or otherwise) for any loss, damage or omission in any way arising from the use of the internet or from access by Provider to networks, applications, electronic data or other systems of the Client Group.

(a)Nothing in the Contract will prevent or restrict Provider, from providing services to other clients (including services which are the same or similar to the Services) or using or sharing for any purpose any knowledge, experience or skills used in, gained or arising from performing the Services subject to the obligations of confidentiality set out in Paragraph 10 unless those other clients’ interests are in competition with the Client. Also, to the extent that Provider possesses information obtained under an obligation of confidentiality to another client or other third party, Provider is not obliged to disclose it to any member of the Client, or use it for the benefit of the Client, however relevant it may be to the Services.

(a)Provider and the Client each agree not, directly or indirectly, to solicit, employ or engage any personnel of the other party who within one year of such action has been involved directly with the provision of the Services or otherwise directly connected with the Contract, except where an individual responds directly to a general recruitment campaign.

(a)Provider may retain copies of documents and files provided by the Client in connection with the Services for the purposes of compliance with professional standards and internal retention policies. However, use of such information retained for these purposes is, in all cases, subject to the

obligations of confidentiality set out in Paragraph 10.

(a)Neither the Provider nor the Client shall use the other’s trademarks, service marks and/or branding in external publicity material without such other party’s prior written consent. However, as a credential of its professional experience and for commercial purposes, the Provider may use the Client’s trademarks and may refer to the names of the Client in presentation materials solely as a reference to Client being a recipient of Services.

(a)Provider understands that the Client may be subject to laws that prohibit bribery and/or providing anything of value to government officials with the intent to influence that person’s actions in respect of the Client. Provider may be subject to similar laws and codes of professional conduct and has its own internal policies and procedures which prohibit illegal or unethical behaviors. In providing the Services, Provider undertakes not to offer, promise or give financial or other advantage to another person with the intention of inducing a person to perform improperly or to reward improper behavior for the benefit of the Client, in each case, in violation of applicable law.

(b)Likewise, Client and Provider commit to comply with all applicable laws and regulations, including anticorruption and anti-bribery rules, and to act with ethical and professional behavior, avoiding any practice that could be a violation of the anticorruption and anti-bribery laws or regulations in any country where this Agreement will be performed.

(c)Annexes A and B to this Contract are incorporated by reference into this Contract as if set forth fully herein.

(a)Nothing discussed prior to execution of the Contract induced, nor forms part of, the Contract except to the extent repeated in the Contract. The Contract supersedes any previous agreement, understanding or communication, written or oral, relating to its subject matter. No variation to the Contract shall be effective unless it is documented in writing and signed by authorized representatives of both parties, provided, however, that the scope of the Services may be changed by agreement of the parties in writing, including by e-mail. If Provider has already started work (e.g., by gathering information, project planning or giving initial advice) at the request of the Client then the Client agrees that the Contract is effective from the start of such work.

(a)Any provisions of the Contract which either expressly or by their nature extend beyond the expiration or termination of the Contract shall survive such expiration or termination.

(b)If any provision of the Contract is found by a court of competent jurisdiction or other competent authorities to be unenforceable, in whole or in part, such provision or the affected part shall not affect the other provisions but such unenforceable provision shall be deemed modified to the extent necessary to render it enforceable, preserving to the fullest extent permissible the intent of the parties set forth herein. Each of the provisions of the Contract shall apply to the fullest extent of the law, whether in contract, statute, tort (including without limitation negligence), or otherwise, notwithstanding the failure of the essential purpose of any remedy. Any references herein to the term “including” shall be deemed to be followed by “without limitation”.

(a)This Contract, and all matters relating to it, (including non-contractual obligations) shall be governed by, and construed in accordance with, the laws of the State of Nevada. Any action or proceeding arising out of or relating to this Contract or the Services shall be brought and maintained exclusively in the State of Nevada. The parties hereby expressly and irrevocably (i) submit to the exclusive jurisdiction of such courts for the purposes of any such action or proceeding and (ii) waive, to the fullest extent permitted by law, any defense of inconvenient forum to the venue and maintenance of such action in any such courts. Nothing in this Paragraph will prevent either party, at any time before or after the dispute resolution procedures are invoked, from commencing legal proceedings to protect any intellectual property rights, trade secrets or confidential information or to preserve any legal right or remedy.

(a)The parties agree to attempt in good faith to resolve any dispute or claim arising out of or in connection with the Contract promptly through negotiations between senior management. Nothing in this Paragraph prevents either party, at any time before or after the dispute resolution procedures are invoked, from commencing legal proceedings to protect any intellectual property rights, trade secrets or confidential information or to preserve any legal right or remedy.

(a)Where there are current or future laws or regulations in any jurisdiction that require disclosure relevant to the Services, the Provider will also comply with those disclosure requirements, to the extent that it is legally obliged to do so.
