On behalf of AC Lordi, we appreciate the opportunity to provide you with professional services. This Engagement Letter governs the relationship between the parties. Each engagement we perform for you will be embodied in a separate Addendum to this Engagement Letter.

1.Term. This Engagement Letter is effective as of the date stated above, and continues until terminated by either party upon 30 days prior written notice to the other party. The provisions of Paragraphs 4, 6, 7, 10, 11, 12, 13, 14, 17 and 18 will survive any termination of this Engagement Letter.

2.Consulting Services. We will provide accounting, internal audit, or business advisory services to you as described in the Addendum # 10 attached and subsequent addenda entered into between us, which we refer to in this Engagement Letter as our “services.”

3.Addenda; Conflicts. Each Addendum must i) be set forth in a written document signed by both parties, ii) list specific services to be provided, and iii) specify rates for service providers, to be valid. Each Addendum will be subject to this Engagement Letter. If there is a conflict between any Addendum and this Engagement Letter, the Addendum will prevail.

4.Ownership. Upon full payment to us, you will own any Work Product, subject to any restrictions set forth in this Engagement Letter or any Addendum, and Work Product is a work for hire made by us for you. We retain all ownership rights to the Know-How and to the extent Know-How is incorporated in the Work Product, we grant you a limited, non-transferable, paid-up, license to use the Know-How in your business to the same extent you may use the Work Product.

5.Independent Contractor. In performing our services under this Engagement Letter, we are an independent contractor. No employer-employee, partnership, joint-venture, or agency relationship exists between us and you. Within any parameters set forth in the Addendum, we retain the discretion to determine how, when and where to perform the services, how to staff them, and what methods to use. We acknowledge that we shall be solely responsible for any national or local income taxes or national or local self-employment taxes arising with respect to the amounts payable hereunder and that we have no supranational, national or local law workers’ compensation rights with respect to the services provided herein. We acknowledge that you shall not provide to us workers’ compensation, disability insurance, Social Security or unemployment compensation coverage nor any other statutory benefit generally granted to your employees. We shall comply at our expense with all applicable provisions of workers’ compensation laws, unemployment compensation laws, federal Social Security law, the Fair Labor Standards Act, federal, state and local income tax laws, and all other applicable federal, state and local laws, regulations and codes relating to terms and conditions of employment required to be fulfilled by employers or independent contractors.

6.Confidentiality. Each party agrees that during and after the term of this Engagement Letter it will keep confidential and will not use or disclose to any third party any confidential or proprietary information learned by such party or disclosed to such party in connection with this Engagement Letter or the services contemplated hereby, except for use or disclosure necessary to perform services under this Engagement Letter. Unless expressly stated in an Addendum, you acknowledge that our services will not involve our storage, transmission, or processing of any personally identifiable information or personal health information. This Paragraph 6 is complementary to and does not supersede any confidentiality or nondisclosure agreement already in force between the parties. You and we acknowledge U.S. federal law (18 U.S.C. § 1833(b)) states that an individual shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret that-(A) is made-(i) in confidence to a Federal, State, or local government official, either directly or indirectly, or to an attorney; and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal.  You and we acknowledge that law further states that an individual who files a lawsuit for retaliation for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual-(A) files any document containing the trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order. For the avoidance of doubt, nothing in this Engagement Letter is intended to, nor shall be construed to, conflict with 18 U.S.C. § 1833(b).

7.Fees and Expenses. Invoices will be based on rates set forth in Addendum and hours worked by our consultants. You will pay applicable out-of-pocket travel-related expenses.

a.Payment. We will invoice you monthly. You will pay us within 30 days of receipt of invoices.

b.Past due amounts. For past due amounts, we may add a 1% monthly service charge on your unpaid balance.

c.Collection fees. We may add the cost of reasonable collection or legal fees and expenses required to collect on your unpaid balance.

d.Additional Fees. We may charge additional fees as mutually agreed if events beyond our control (including your acts or omissions) affect our ability to perform the services as originally planned or if you ask us to perform additional tasks.

e.Termination Charges. If you terminate the services without cause before completion of an Addendum, you will pay us for our work performed to the effective date of termination at the applicable rates, and reimburse us for any incremental wind-down costs we may incur on account of such early termination, such as severance or similar costs with respect to personnel and mitigating our costs connected with commitments we entered into in order to perform the services.

f.Subpoenas, etc. If either party (the “Subpoenaed Party”) is required by subpoena, applicable law, investigation or other legal process or government action to produce information or personnel as witnesses with respect to the services or this Engagement Letter the other party will reimburse the Subpoenaed Party for any professional time and expenses (including reasonable external and internal legal costs) incurred to respond to the demand or request, unless the Subpoenaed Party is a party to the proceeding or the subject of the investigation.

g.Taxes. All fees, charges and other amounts payable to us hereunder exclude any sales, use, excise, value added or other applicable taxes, tariffs or duties. Payment of any taxes is your responsibility, except taxes based on our net income or our employment relationships.

h.No Benefits. Subject to Section 22, in performing our services under this Engagement Letter, we acknowledge and agree that none of our service providers are eligible for any of your company’s employee benefits (including without limitation any stock options, stock purchases, equity award, deferred compensation, pension, thrift, profit sharing, employee stock ownership, group life insurance, medical coverage, disability insurance, education, or other retirement or employee benefits), and, to the extent one of our service providers would be eligible for such employee benefits but for the express terms of this Engagement Letter, we hereby expressly decline to participate.

8.Cooperation. You will cooperate with us in our performing services for you, including assigning a qualified person to oversee your part of the project, providing us with reasonable facilities and timely access to your data, information and personnel, and any specific resources or cooperation set forth in the Addendum. You are responsible for your employees’ and agents’ performance, and for the accuracy and completeness of all data and information you provide to us.

9.Warranties. We represent and warrant that our services will be performed in good faith in a professional and workmanlike manner with professional diligence and skill appropriate to our industry and responsibility. We further represent and warrant that we are not under any pre-existing obligation in conflict or in any way inconsistent with the provisions of this Engagement Letter. We represent and warrant that our performance of all of the terms of this Engagement Letter will not breach any agreement to keep in confidence proprietary information that we have acquired in confidence or in trust prior to this Engagement Letter. We make no other representations or warranties.

10.Work Product. Any Work Product is for your internal use only, which includes use by your agents, representatives, and affiliates, subject to any restrictions set forth in this Engagement Letter or any Addendum. Any Work Product will reflect our observations as of the date of issuance. We do not intend and are not obliged to update, revise, or amend the Work Product, but reserve the right to do so.

11.Disclaimers. Our services are not intended to be an audit, examination, attestation, special report, or agreed-upon procedures engagement, as those services are defined in the American Institute of Certified Public Accountants (AICPA) literature applicable to such engagements conducted by independent auditors. Accordingly, our services will not result in the issuance of a written communication to third parties by us or other form of assurance with respect to your internal control system over financial reporting or otherwise, or your compliance with laws, regulations or other matters. You may not rely on any draft Work Product we may provide, and no third party may rely on our Work Product at all without our express written permission. You agree not to include our Work Product in any filing with the Securities Exchange Commission or any other body, unless otherwise provided in an Addendum. We will not perform any management functions, make management decisions, or perform in a capacity equivalent to that of your employees, except as a necessary incident of our services set forth in an Addendum. Further, we give no guaranty of results that may be achieved by you through our services. We will rely on the information you make available, without independent evaluation or verification, unless such evaluation or verification is an express part of our services according to the applicable Addendum. You represent and warrant that nothing you provide to us will infringe the intellectual property, trade secret, or other rights of third parties. Our services may include observations or recommendations, but all decisions in connection with the implementation of such observations and recommendations are your sole responsibility. Any use you may make of our Know-How is “as-is.” We do

not make any representation as to sufficiency of your compliance procedures, unless evaluation of such procedures is an express part of our services according to the applicable Addendum, nor are we providing any legal advice.

12.Limitation of Liability. Neither party will be liable to the other party or to a third party for any indirect, incidental, special, punitive, exemplary, or consequential damages, costs, expenses, or losses, including but not limited to damages based on lost revenues, lost profits, or lost business opportunities. We shall not be in the aggregate liable for any reason for a total amount in excess of the fees we receive under the Addendum governing the services which gave rise to the liability. These dollar limitations on our liability in the preceding sentence will not apply to the extent you incur losses and damages on account of our own gross negligence, fraud or other willful misconduct.
