of termination (subject to the attainment of any applicable performance goals).

representative of the Company except to the extent permitted under Employee Protections (as set forth in Section 7(e)(iv) of this Agreement)

Executive shall use Executive’s best efforts to consult with the Company prior to responding to any such order or subpoena, and

except as authorized in performance of Executive’s duties hereunder, Executive shall not use or disclose any confidential or proprietary

trade secrets, customer lists, drawings, designs, marketing plans, management organization information (including, but not limited to,

the boards of directors of the Company Group, or to the management of the Company Group), operating policies or manuals, business plans,

(b) Non-Competition.

(i) Executive represents that Executive has provided to the Company all copies of any non-competition or other agreements and

related documents that in any way pertain to Executive’s ability to seek employment as of this date. Executive represents that

Executive has the legal right to accept and perform the position with the Company herein without restriction, other than restrictions

pertaining to the confidentiality of former employers’ proprietary information; and (ii) During the period beginning

on the date hereof and ending twelve months after the termination of Executive’s employment with the Company (the “Restriction

battery systems, applications in commercial and industrial, micro grid, telecom, military, renewables, and residential markets, and the

provision of services related thereto.

of Employees. During the Restriction Period, Executive shall not, directly or indirectly, for Executive’s own account or for

the account of any other natural person, partnership, limited liability company, association, corporation, company, trust, business trust,

governmental authority or other entity (each, a “Person”) in any jurisdiction in which the Company has commenced or has documented

plans, as of the termination of Executive’s employment with the Company, to commence operations during the Employment Period, (i)

solicit for employment, employ or otherwise interfere with the relationship of the Company Group with any natural person throughout the

world who is or was employed by or otherwise engaged to perform services for the Company Group at any time (a) during the Employment

Period, or (b) during the twelve month period immediately preceding the commencement of such Restriction Period, in each case, other

than any such solicitation or employment on behalf of or at the request of the Company Group during the Employment Period; or (ii) induce

any employee of the Company Group to engage in any activity which Executive is prohibited from engaging in under any of this Section

8 or to terminate such employee’s employment with the Company.

(d) Non-Solicitation

account or for the account of any other Person, in any jurisdiction in which the Company Group has commenced or has made plans to commence

operations, solicit, interfere with, or otherwise attempt to establish any business relationship of a nature that is competitive with

the Business or relationship of the Company Group with any Person throughout the world which is or was a customer, client, distributor,

supplier or vendor of the Business of the Company Group at any time during the Employment Period (in the case of such prohibited activity

occurring during such time) or during the twelve month period preceding the commencement of such Restriction Period (in the case of such

prohibited activity occurring during the Restriction Period but after the date of Executive’s termination of employment with the

Company), other than any such activity on behalf of or at the request of the Company Group during the Employment Period.

(e) Works

for Hire.

(i) Generally.

Executive agrees that the Company shall own all right, title and interest (including, but not limited to, patent rights, copyrights,

trade secret rights and other rights throughout the world) in any inventions, works of authorship, ideas or information made or conceived

or reduced to practice, in whole or in part, by Executive (either alone or with others) during the Employment Period (collectively “Developments”);

provided, however, that the Company shall not own Developments for which no equipment, supplies, facility, trade secret information or

Confidential Information of the Company was used and which were developed entirely on Executive’s time, and (A) which do not relate

(I) to the business of the Company Group or (II) to the actual or demonstrably anticipated research or development of the Company Group,

and (B) which do not result from any work performed by Executive for the Company.

(ii) Disclosure;

Assignment. Subject to Section (e)(i), Executive will promptly and fully disclose to the Company, or any persons designated by it,

any and all Developments made or conceived or reduced to practice or learned by Executive, either alone or jointly with others during

the Employment Period. Executive hereby assigns all right, title and interest in and to any and all of these Developments to the Company.

Executive shall further assist the Company, at the Company’s expense, to further evidence, record, and perfect such assignments,

and to perfect, obtain, maintain, enforce, and defend any rights specified to be so owned or assigned. Executive hereby irrevocably designates

and appoints the Company and its agents as attorneys-in-fact to act for and on Executive’s behalf to execute and file any document

and to do all other lawfully permitted acts to further the purposes of the foregoing with the same legal force and effect as if executed

by Executive.

(iii) Copyright

Act; Moral Rights. In addition, and not in contravention of this Section (e)(i) or Section (e)(ii), Executive acknowledges that all

original works of authorship which are made by Executive (solely or jointly with others) within the scope of employment and which are

protectable by copyright are “works made for hire,” as that term is defined in the United States Copyright Act (17 USC §101).

To the extent allowed by law, this Section (e) includes all rights of paternity, integrity, disclosure and withdrawal and any other rights

that may be known as or referred to as “moral rights” (collectively, “Moral Rights”). To the extent Executive

retains any such Moral Rights under applicable law, Executive hereby waives such Moral Rights and consents to any action consistent with

the terms of this Agreement with respect to such Moral Rights, in each case, to the full extent of such applicable law. Executive will

confirm any such waivers and consents from time to time as requested by the Company.

(iv) Employee

Protections.

(A) Executive

has the right under U.S. federal law to certain protections for cooperating with or reporting legal violations to the Securities Exchange

Commission (the “SEC”) and/or its Office of the Whistleblower, as well as certain other governmental entities and self-regulatory

organizations. As such, nothing in this Agreement or otherwise (including any confidentiality provision) is intended to prohibit Executive

from disclosing this Agreement to, or cooperating with or reporting violations to, the SEC or any other such governmental agency or entity

or self-regulatory organization (each, a “Governmental Authority”), and Executive may do so without notifying the Company.

No member of the Company Group may retaliate against Executive for any of these activities (including reporting internally to the Company

Group or to any Governmental Authority), and nothing in this Agreement or otherwise would require Executive to waive any monetary award

or other payment that Executive might become entitled to from the SEC or any other Governmental Authority.

(B) Section

1833(b) of Title 18 of the United States Code states “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 (i) is made (a) in confidence to a Federal, State, or local government

official, either directly or indirectly, or to an attorney and (b) solely for the purposes of reporting or investigating a suspended

violation of law or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under

seal.” Accordingly, the Company and Executive have the right to disclose trade secrets in confidence to Federal, State, and local

government officials, or to an attorney, for the sole purpose of reporting or investigating a suspected violation of law. The Company

and Executive also have the right to disclose trade secrets in a document filed in a lawsuit or other proceeding, but only if the filing

is made under seal and protected from public disclosure. Nothing in this Agreement is intended to conflict with Section 1833(b) of Title

18 of the United States Code or create liability for disclosures of trade secrets that are expressly allowed by Section 1833(b) of Title

18 of the United States Code (Section 7(e)(iv)(A) and (B) are hereby collectively referred to as “Employee Protections”).

(f) Non-Disparagement.

Executive agrees that Executive shall neither, directly or indirectly, engage in any conduct or make any statement (including through

social media) disparaging or criticizing in any way the Company Group, or any of their personnel, nor engage in any other conduct or

make any other statement that could be reasonably expected to impair the goodwill of the Company Group, or the reputation of the Company

Group, in each case, except to the extent permitted by Employee Protections set forth in this Agreement. This paragraph does

not restrict or impede Executive from exercising protected rights to the extent that such rights cannot be waived by agreement or from

complying with applicable law or regulation or a valid order of a court of competent jurisdiction or an authorized government agency,

provided that such compliance does not exceed what is required by the law, regulation, or order, and provided further that Executive

promptly provides written notice of any such order to the Company.

Executive shall promptly deliver to the Company or destroy (if requested by the Company) (i) all property of the Company Group

then in Executive’s possession; and (ii) all documents and data of any nature and in whatever medium of the Company Group, and

Executive shall not take with Executive any such property, documents or data or any reproduction thereof, or any documents containing

or pertaining to any Confidential Information.

(h) Confidentiality

of Agreement; Governmental Agency Exception. The parties to this Agreement agree not to disclose its terms to any Person, other than

their attorneys, accountants, financial advisors or, in Executive’s case, members of Executive’s immediate family or, in

the Company’s case, for any reasonable purpose that is reasonably related to its business operations; provided, that this Section

(h) shall not be construed to prohibit any disclosure required by law or in any proceeding to enforce the terms and conditions of this

Agreement. Notwithstanding anything to the contrary contained in this Agreement, this Agreement does not limit Executive’s ability

to communicate with any government agency or otherwise in accordance with Employee Protections as set forth in this Agreement. This Agreement

does not limit Executive’s right to receive an award for information provided to any government agencies.

party may reasonably request from time to time, to effectuate the provisions and purpose of this Agreement.

(i) Section

409A.

(i) The

parties intend that any amounts payable hereunder comply with or are exempt from Section 409A (“Section 409A”) of

the Internal Revenue Code of 1986, as amended (the “Code”) (including under Treasury Regulation §§ 1.409A-1(b)(4)

(“short-term deferrals”) and (b)(9) (“separation pay plans,” including the exceptions under subparagraph (iii)

and subparagraph (v)(D)) and other applicable provisions of Treasury Regulation §§ 1.409A-1 through A-6). For purposes of Section

409A, each of the payments that may be made under this Agreement shall be deemed to be a separate payment for purposes of Section 409A.

This Agreement shall be administered, interpreted, and construed in a manner that does not result in the imposition of additional taxes,

penalties, or interest under Section 409A. The Company and may make amendments to the Agreement, as are necessary or desirable to avoid

the imposition of taxes, penalties, or interest under Section 409A. Neither the Company nor Executive shall have the right to accelerate

or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A. With

respect to the time of payments of any amounts under the Agreement that are “deferred compensation” subject to Section 409A,

references in the Agreement to “termination of employment” (and substantially similar phrases) shall mean “separation

from service” within the meaning of Section 409A. For the avoidance of doubt, it is intended that any expense reimbursement made

to Executive hereunder shall be exempt from Section 409A. Notwithstanding the foregoing, if any expense reimbursement made hereunder

shall be determined to be “deferred compensation” within the meaning of Section 409A, then (a) the amount of the indemnification

payment or expense reimbursement during one taxable year shall not affect the amount of the expense reimbursement during any other taxable

year, (b) the expense reimbursement shall be made on or before the last day of Executive’s taxable year following the year

in which the expense was incurred and (c) the right to expense reimbursement hereunder shall not be subject to liquidation or

exchange for another benefit.

(ii) In

the event that Executive is a “specified employee” (as described in Section 409A), and any payment or benefit payable pursuant

to this Agreement constitutes deferred compensation subject to the six-month delay requirement described in Section 409A(2)(b), then

no such payment or benefit shall be made before six months after Executive’s “separation from service” (as described

in Section 409A) (or, if earlier, the date of the Executive’s death). Any payment or benefit delayed by reason of the prior sentence

shall be paid out or provided in a single lump sum at the end of such required delay period in order to catch up to the original payment

schedule.

(iii) The

parties hereto intend that the Severance payments up to two times the dollar limit in effect under Section 401(a)(17) of the Code for

the year in which Executive’s “separation from service” (as described in Section 409A) occurs shall be exempt from

Section 409A to the extent permitted under Treasury Regulation Section 1.409A-1(b)(9)(iii) (the “two- times/two-year” exemption).

In determining which installments of Severance are taken into account in applying the two-times/two-year exemption, any other exemptions

from Section 409A (including, the short-term deferral exception, if applicable) shall be taken into account first and the immediately

following installments shall then be applied toward the two-times/two-year exception (up to the applicable dollar limit). Neither

the Company, its affiliates nor any other person makes any representation that any or all of the payments contemplated the Agreement

shall be exempt from or comply with Section 409A or makes any undertaking to preclude Section 409A from applying to any such payment.

Notwithstanding anything to the contrary in the Agreement, neither the Company, its Affiliates, nor any person acting on behalf thereof,

shall be liable to Executive or to any other person by reason of any acceleration of income, or any additional tax, asserted by reason

of the failure of the Agreement or any payment or benefit thereunder to satisfy the requirements of Section 409A.

(j) Section

280G.

(i) Notwithstanding

anything to the contrary contained in this Agreement or otherwise, to the extent that any payment, distribution or acceleration of vesting

to or for the benefit of Executive by the Company (within the meaning of Section 280G of the Code and the regulations thereunder), whether

paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the “Total Payments”),

is or will be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then the Total Payments

shall be reduced (but not below zero) to the Safe Harbor Amount (as defined below) if and to the extent that a reduction in the Total

Payments would result in Executive retaining a larger amount, on an after-tax basis (taking into account federal, state and local income

and employment taxes and the Excise Tax), than if Executive received the entire amount of such Total Payments in accordance with their

existing terms (taking into account federal, state, and local income and employment taxes and the Excise Tax). For purposes of this Agreement,

the term “Safe Harbor Amount” means the largest portion of the Total Payments that would result in no portion of the Total

Payments being subject to the Excise Tax. To effectuate the foregoing, the Company shall reduce or eliminate the Total Payments by first

reducing or eliminating the portion of the Total Payments which are payable in cash and then by reducing or eliminating non-cash payments,

in each case, starting with the payments to be made farthest in time from the Determination (as defined below).

(ii) The

determination of whether the Total Payments shall be reduced as provided in Section 10(j)(i) and the amount of such reduction shall be

made at the Company’s expense by an accounting firm selected by Company from among the 10 largest accounting firms in the United

States or by qualified independent tax counsel (the “Determining Party”); Such Determining Party shall provide its determination

(the “Determination”), together with detailed supporting calculations and documentation to the Company and Executive, within

10 business days of the termination of Executive’s employment or at such other time determined by the Company.

(iii) If,

notwithstanding any reduction described in this Section (j)(iii), the Internal Revenue Service (“IRS”) determines that Executive

is liable for the Excise Tax as a result of the receipt of any of the Total Payments or otherwise, then Executive shall be obligated

to pay back to the Company, within 30 calendar days after a final IRS determination or in the event that Executive challenges the final

IRS determination, a final judicial determination, a portion of the Total Payments equal to the “Repayment Amount”. The “Repayment

Amount” with respect to the payment of benefits shall be the smallest such amount, if any, as shall be required to be paid to the

Company so that Executive’s net after-tax proceeds with respect to the Total Payments (after taking into account the payment of

the Excise Tax and all other applicable taxes imposed on the Payment) shall be maximized. The Repayment Amount shall be zero if a Repayment

Amount of more than zero would not result in Executive’s net after-tax proceeds with respect to the Total Payments being maximized.

If the Excise Tax is not eliminated pursuant to this Section 10 (j)(iii), Executive shall pay the Excise Tax.

(iv) Notwithstanding

any other provision of this Section 10(j), if (i) there is a reduction in the Total Payments as described in this Section 10(j), (ii)

the IRS later determines that Executive is liable for the Excise Tax, the payment of which would result in the maximization of Executive’s

net after-tax proceeds (calculated as if Executive’s benefits had not previously been reduced), and (iii) Executive pays the Excise

Tax, then the Company shall pay to Executive those payments or benefits which were reduced pursuant to this Section 10(j) as soon as

administratively possible after Executive pays the Excise Tax (but not later than March 15 following the calendar year of the IRS determination)

so that Executive’s net after-tax proceeds with respect to the Total Payments are maximized.

(v) If,

following a reduction of the Total Payments pursuant to Section 10(j)(i), the Determining Party or a court of competent jurisdiction

determines that the Total Payments were reduced to a greater extent than required under Section 10(j), then the Company shall as soon

as administratively possible (but not later than by March 15 following the calendar year of such determination) pay the amount of such

excess reduction to or for the benefit of Executive, together with interest at the applicable federal rate (as defined in Section 7872(f)(2)(A)

of the Code), from the date the amount would have otherwise been paid to Executive until the payment date.

(vi) To

the extent requested by Executive, the Company shall cooperate with Executive in good faith in valuing, and the Determining Party shall

take into account the value of, services provided or to be provided by Executive (including, without limitation, Executive’s agreeing

to refrain from performing services pursuant to a covenant not to compete or similar covenant, before, on or after the date of a change

in ownership or control of the Company (within the meaning of Q&A-2(b) of the final regulations under Section 280G of the Code),

such that payments in respect of such services may be considered reasonable compensation within the meaning of Q&A-9 and Q&A-40

to Q&A-44 of the final regulations under Section 280G of the Code and/or exempt from the definition of the term “parachute

payment” within the meaning of Q&A-2(a) of the final regulations under Section 280G of the Code in accordance with Q&A-5(a)

of the final regulations under Section 280G of the Code.

(k) Counterparts.

This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which together shall constitute

one and the same instrument. The parties hereto agree to accept a signed facsimile copy or “PDF” of this Agreement as a fully

binding original.

(l) Headings.

hereof or to affect the meaning or interpretation hereof.

or any unasserted claims against Company to anyone. By this Agreement, Employee does not waive any entitlement to any vested benefit,

including Employee’s entitlement to life insurance under any applicable Company policies. However, by this Agreement, Employee

(i) the

existence and terms of this Agreement; and

(ii) the

claims which were or could have been asserted, either expressly or by implication, by Employee in any action against Company.

(b) These

matters are to be held in strict confidence by Employee. Employee agrees that all the above-described matters shall be kept confidential

and shall not be discussed, disclosed or otherwise revealed to any person or entity, in either general or specific terms except:

(i) to a member of Employee’s immediate family, attorney or tax advisor; (ii) with the prior written consent of Company;

(ii) pursuant to an order of a court or an order or request by a governmental body or agency having jurisdiction to issue such order

or request, in which event Employee shall make every reasonable effort to notify Company prior to any such disclosure. To the extent

that Employee provides details to anyone as permitted in paragraph (b)(i), Employee will advise any person of the obligation to keep

the terms of this Agreement strictly confidential. Additionally, no provision in this Agreement prohibits or restricts Employee

(or Employee’s attorney) from engaging in legally protected activity (such as for example engaging in concerted or protected activity

pertaining to the terms and conditions of employment) or initiating communications directly with, or responding to any inquiry from,

or providing testimony before, any self-regulatory organization or state or federal regulatory authority regarding this Agreement, the

underlying facts or circumstances or any matters related to Employee’s employment with Company. This Agreement does not require

Employee to contact Company regarding the subject matter of any such communications before engaging in such communications. Employee

may also make disclosures of information made confidential by this Agreement for accounting purposes, tax purposes, securing government

benefits, or to Employee’s lawyer or accountant, and nothing herein prohibits Employee from disclosing any information or from

making any statements as permitted or required by applicable law, including information with respect to a sexual assault dispute or sexual

harassment dispute, or regarding sexual misconduct. No provision in this Agreement has the purpose or shall have the effect of concealing

details relating to any claim of discrimination, retaliation, or harassment.

8. Affirmations:

To the extent Employee may be classified as nonexempt, is later deemed nonexempt, or later claims Employee should have been classified

as nonexempt, Employee affirms that Employee has reported all hours worked as of the date of this agreement and has been paid and/or

has received all leave (paid or unpaid), compensation, regular wages, bonuses, commissions, vacation pay, shares, stock options and/or

benefits to which Employee may be entitled and that no other leave (paid or unpaid), compensation, wages, bonuses, commissions and/or

benefits are due to Employee. Employee furthermore affirms that Employee has no known workplace injuries or occupational diseases and

has been provided and/or has not been denied any leave requested, allowed, or provided for under the Family and Medical Leave Act, and/or

any other federal, state, or local leave law. Employee further affirms Employee has not complained of and is not aware of any fraudulent

activity or any act(s) which would form the basis of a claim of fraudulent or illegal activity of Company.

9. No

Admission of Liability: This Agreement shall not in any way be construed as an admission by Company that it has acted wrongfully

with respect to Employee or any other person or employee, or that Employee has any rights whatsoever against Company. Company specifically

disclaims any liability to or wrongful acts against Employee. It is fully understood and agreed that each Party shall pay that Party’s

own attorney’s fees and costs pertaining to the resolution of this matter.

10. Return

Agreement, by the Termination Date or upon earlier request by Company, Employee agrees to return to Company prior to the payment of any

consideration under this Agreement, all documents, tangible things and/or all other items Employee has received or obtained from Company

and/or property of Company including computer, mobile phone, keys, security cards, equipment, documents, supplies, customer lists, customer

information, and confidential documents. Employee further covenants and agrees that Employee shall not directly or indirectly access,

interfere with, tamper with, alter, damage, or destroy Company’s property, including electronic files, or any part thereof. The

obligations under this Section are subject to Employee’s legally protected rights to communicate with government bodies and agencies

and to engage in legally protected activity. If Employee fails to return any Company property, Company may in its sole discretion make

written demand for its return and/or may take legal action to require return/payment. As allowed by applicable law, in the event Employee

fails to return all Company property upon two written demands, Employee will be deemed to have agreed that Company property belongs to

Company and that Employee is refusing to return Company property. Accordingly, Employee expressly agrees that a presumption shall be

created that (1) Employee is required to return Company property; and (2) the applicable sums are due and owing. The demands shall be

deemed received if sent to Employee’s last known address in Company’s payroll system, otherwise delivered to Employee’s

actual address and/or actually received by Employee.

11. Knowing

and Voluntary Release:

(a) Employee

further states that Employee has carefully read this Agreement and knows and understands its contents and that Employee executes it as

Employee’s own free act and deed and enters into the Agreement knowingly and voluntarily.

(b) Employee

acknowledges and agrees that Employee has been given the opportunity to consider this Agreement for a period of twenty-one (21) days,

has been advised to review this Agreement with Employee’s counsel, and has seven (7) days after signing this Agreement to revoke

the portions of it relating to the release of claims for age discrimination under the Age Discrimination in Employment Act and the Older

Workers’ Benefit Protection Act. Such revocation must be made in writing and sent to Company’s Chief Legal Officer, Michael

Silberman (msilberman@eose.com). If Employee signs this Agreement prior to the end of any consideration period described herein, Employee

specifically acknowledges that Employee does so knowingly and voluntarily.

consideration that Employee is eligible to receive under this Agreement will not be paid until the expiration of all applicable revocation

periods and/or rescission periods set forth herein. All applicable revocation and/or rescission periods set forth herein will run concurrently,

subject to applicable law.

12. Disparaging

Statements: Subject to the Employee Protections as set forth in the Employment Agreement, Employee agrees not to make any disparaging

statements concerning the Company.

13. Non-Waiver:

No failure or delay by any Party in exercising any right, power or privilege under this Agreement shall constitute a waiver of such right,

power or privilege, nor shall any single or partial exercise of such right, power or privilege preclude any other or further exercise

ATTACHMENT A

TO SEPARATION AGREEMENT AND GENERAL RELEASE

Dispute Resolution

Procedures

1. Mediation:

(a) If

a dispute arises within the scope of this Agreement that was not resolved through consultation with Company’s Human Resources,

the Parties shall first submit the dispute or controversy to non-binding mediation in accordance with the following procedure: Either

Employee or Company can initiate the dispute resolution process by submitting a written request to mediate to the other Party. Requests

to Company should be addressed to the attention of Company’s Legal Department. The mediation shall be held before a qualified neutral

mediator, and the mediation shall take place in the metropolitan area of the division or office to which the Employee was assigned at

the time of the dispute. The Parties shall jointly designate a mediator. Within fifteen (15) business days of receipt of the initiating

Party’s written request for mediation, the Parties shall exchange a written list of each Party’s proposed mediators and shall

make a good faith effort to agree on a mutually acceptable mediator. If the Parties cannot agree on a mediator within thirty (30) business

days of the date of the written request for mediation, the mediation will be administered by the American Arbitration Association ("AAA"),

and AAA will designate a qualified mediator. The Employment Arbitration Rules and Mediation Procedures can be found at www.adr.org.

(b) To

initiate mediation proceedings with the AAA in circumstances where the Parties cannot agree on a mediator, the Party initiating the mediation

request shall first notify the other Party in writing that no agreement can be reached on mediator selection, and then both Parties shall

submit a “Request for Mediation Form” to the AAA. (Online forms are available at www.adr.org). The designated mediator

shall have experience and expertise in the subject matter of the dispute. Company and the Employee are obligated to make a good faith

effort to resolve the issue through mediation, and to participate in the mediation session to its conclusion. The Parties are entitled

to a full day mediation session under this Agreement; however, the Parties may jointly agree to a half-day mediation session. Mediation

sessions are to be conducted with as little formality and technicality as possible. The Parties shall equally share the costs of mediation,

unless the Parties agree otherwise, and each Party shall bear its/his/her own attorneys’ fees and costs in connection with the

mediation of any disputes under this Agreement. To ensure that mediation is held in a non-prejudicial manner and to encourage candid

discourse among the Parties, all information disclosed in the course of mediation is to remain confidential.

2. Binding

Arbitration:

(a) If

the dispute is not resolved through mediation, Employee and Company agree to resolve the dispute exclusively by binding arbitration under

the Federal Arbitration Act (“FAA”) and this Agreement. Preliminary injunctive relief and other provisional remedies

in aid of arbitration may be sought by either the Employee or Company in a court of competent jurisdiction under applicable law, but

the arbitrator alone may award permanent injunctive relief. All proceedings shall be confidential as allowed by law.

(b) Employee

acknowledges and agrees that proceeding under this Agreement is the exclusive remedy for all disputes arising from or related to his/her

employment with or separation from Company, as well as any disputes related to this Agreement. In addition, both Employee and Company

agree to waive all rights to a civil court action regarding any disputes within the scope of this Agreement. This means that only the

arbitrator, and not a judge or jury, will decide the dispute.

under this Agreement will be governed by the Federal Arbitration Act, 9 U.S.C. § 1 et seq., and resolved by a neutral arbitrator

in a binding arbitration administered by the AAA under the arbitration-related portion of the AAA's Employment Arbitration Rules and

Mediation Procedures (the "Arbitration Rules"), in effect on November 1, 2009, including indigency determination procedures.

The Arbitration Rules are available at http://www.adr.org. In the case of a conflict between the AAA Rules and this Agreement, this Agreement

shall control.

(d) The

interpretation and enforcement of this dispute resolution agreement shall be governed exclusively by the Federal Arbitration Act. Employee

understands and agrees that this Agreement applies to all claims arising from or related to his/her employment, except claims filed under

workers' compensation and unemployment insurance statutes and administrative charges filed under the National Labor Relations Act, Title

VII, or other governmental agency charges, although civil complaints arising from such charges are still subject to this Agreement and

must be submitted to confidential binding arbitration in accordance with the terms of this Agreement. As noted above, if Employee would

otherwise be legally required to exhaust administrative remedies and/or any other prerequisites before bringing suit on any claim in

court, Employee must exhaust his/her administrative remedies and/or satisfy any other legally required prerequisites before making a

demand for arbitration of any such claims. All statutes of limitation that would be applied if the applicable dispute was filed in court

of competent jurisdiction shall apply to disputes under this Procedure. In the event a court orders the Parties to arbitration and/or

any other form of ADR under this Procedure in a case where the suit was initially filed within the applicable statute of limitations

and within other applicable jurisdictional deadlines, the Party seeking affirmative relief in the case must make the required filings

with AAA within 45 days of the date of the court order, or the case shall be dismissed with prejudice. Any case not submitted to Arbitration

or filed in court within the applicable statute of limitations or other applicable jurisdictional deadline shall be subject to dismissal

in accordance with applicable law. This provision is not intended to constitute a waiver of the obligations of the Parties to submit

disputes in accordance with this policy, but as a time limit for cases not otherwise time-barred to be submitted to arbitration.

(e) Unless

otherwise agreed by the Parties, arbitration shall take place in the city in which the Division office of the division or corporate office

or equivalent to which the Employee was assigned is located. Employee will pay AAA's filing fee for disputes arising under "employer-promulgated

plans" under the Arbitration Rules and bear his/her own attorney's fees and costs of preparing the case, unless the arbitrator

awards such fees and costs. The arbitrator is empowered to award attorneys’ fees and costs to either Party based on applicable

law. Company will pay the remaining part of the filing fee, AAA's administrative fees for such disputes, and the fees and expenses of

the arbitrator and it will provide or pay for the hearing facilities. Employee acknowledges that Company's payment of such fees shall

in no way affect the neutrality of the arbitrator and will stipulate to same prior to the commencement of the arbitration.

(f) In

rendering an award, the arbitrator shall determine the rights and obligations of the Parties according to applicable law and the arbitrator's

decision shall also be governed by applicable law, as though the matter were before a court of law.

(g) Employee

understands that, notwithstanding anything to the contrary in the AAA Arbitration Rules, and in consideration for the relaxed standards

of evidence and speed of arbitration proceedings, Employee and Company agree to arbitrate any claims individually and further agree there

shall be no class actions, collective actions, multi-plaintiff arbitrations, or class arbitrations of any claims within the scope of

this Agreement. The arbitrator shall not have power to treat any claim as a class, collective, multi-plaintiff, or consolidated claim.

This means that arbitration may only proceed on an individual basis.

(h) Employee

further understands that, notwithstanding anything to the contrary in the AAA Arbitration Rules, Employee and Company agree that formal

discovery in any arbitration proceeding shall be limited to four (4) depositions per side; fifteen (15) interrogatories per side; and

requests for production of documents/things shall be limited to thirty (30) document categories per side. Provided, however, that the

arbitrator shall have the power to increase the number of depositions, document requests, and interrogatories upon a showing of good

cause and substantial need and that the requested discovery is not duplicative or cumulative and cannot be obtained by less-intrusive,

less-burdensome, and less-expensive means. Documents and information that are equally available to each Party, such as information available

in the public domain, may not be requested through discovery.

(i) Employee

and Company further agree that a Party may serve on the opposing Party an offer to settle, compromise and/or allow judgment on specified

terms, in accordance with the requirements of any state or local law or rule providing for offers of settlement, compromise and/or judgment

that exist in the geographic location of the arbitration proceeding. And any such offers shall be governed by applicable state or local

law. If there is no applicable state or local law in effect concerning offers of settlement, compromise, and/or judgment in the geographic

location of the arbitration proceedings, the Parties are entitled to make an offer of judgment in accordance with the requirements of

Rule 68 of the Federal Rules of Civil Procedure. If the opposing Party serves timely written notice accepting the offer, either Party

may then file the offer and notice of acceptance, plus proof of service, with the arbitrator. The arbitrator must then enter a written

arbitration award confirming judgment in accordance with the terms specified in the accepted offer. An unaccepted offer is considered

withdrawn, but it does not preclude a later offer. The impact of an unsuccessful offer will be determined by the Arbitrator in accordance

with applicable law.

(j) Either

Party may file dispositive motions of the kind allowed by the Federal Rules of Civil Procedure, and the arbitrator shall timely rule

on such motions in accordance with applicable law.

(k) Any

arbitration award shall be accompanied by a written statement containing a summary of the issues in controversy, a description of the

award, and an explanation of the essential findings and conclusions. Such decision shall be final, conclusive, and binding on the Parties

to the arbitration. The decision of the arbitrator shall be made within thirty (30) days following the close of the hearing. Employee

and Company agree the award shall be enforceable by any state or federal court of competent jurisdiction within the state in which the

Employee works or worked for Company at the time the dispute arose.

(l) If

any part of this arbitration procedure is in conflict with any applicable law, the law shall govern, and that part of this arbitration

procedure shall be reformed and construed to the maximum extent possible in conformance with the applicable law. The arbitration procedure

shall remain otherwise unaffected and enforceable. This Agreement is not intended to interfere with or restrict protected concerted activities

pursuant to the National Labor Relations Act.
