1.1Term of Employment. Executive’s employment under this Agreement shall commence on October 1, 2020 (the “Start Date”) and continue until the third annual anniversary of such date, unless terminated earlier pursuant to Article III herein (the “Initial Employment Term”). The Employment Term shall be extended automatically for successive one-year periods unless, at least 60 days prior to expiration of the Employment Term, either party gives written notice to the other party that he/it does not wish to renew the Agreement (such one year extension(s) and the Initial Employment Term to be, collectively, the “Employment Term”). Delivery of a notice of non-renewal of the Agreement by either the Executive or the Company will not be considered a resignation or termination under this Agreement.

1.2Position and Duties. During the Employment Term, Executive shall hold the position of Senior Vice President – Chief Human Resources and Administrative Officer, and shall report to the Company’s Chief Executive Officer. Executive shall perform such duties and responsibilities as are consistent with a senior executive of the Company and those duties as may be assigned to Executive by the Chief Executive Officer from time to time. Executive shall devote Executive’s full business time, attention, skill and energy to the business and affairs of the Company, and shall use Executive’s reasonable best efforts to perform such responsibilities in a diligent, loyal, and businesslike manner so as to advance the best interests of the Company. Executive shall act in conformity with Company’s written and oral policies and within the limits, budgets and business plans set by the Company, and shall adhere to all rules and regulations in effect from time to time relating to the conduct of employees of the Company. Executive’s office will be at the principal corporate offices of the Corporation, and Executive will be expected to conduct his activities from such office other than when traveling on behalf of the Company. Notwithstanding the foregoing, Executive shall be permitted to devote a reasonable amount of time and effort to civic and charitable organizations and managing personal investments; but only to the extent that such activities, individually or as a whole, do not materially interfere with the execution of Executive’s duties hereunder, or otherwise violate any provision of this Agreement. Executive shall not become involved in the management of any corporation, partnership or other entity, including serving on the board of directors of any publicly traded company, without the written consent of the Corporation’s Board of Directors (the “Board”).

1.3Service on Board. The Company may require Executive to serve without additional compensation as a member of the Board or as an officer or director of any of the Corporation’s subsidiaries.

Executive will be eligible to participate in any annual performance bonus plans and long-term incentive plans established or maintained by the Company for certain senior managers including, but not limited to, the Annual Bonus Plan, 2017 Long-Term Incentive Plan or such similar or successor plans as the Company may establish. Such bonus will be paid in accordance with the Company’s standard practice, but in any event no later than 2.5 months after the end of the calendar year in which Executive earns such bonus.

The Company reserves the right to modify, suspend or discontinue any and all of the plans, practices, policies and programs at any time without recourse by Executive, so long as Company takes such action generally with respect to other similarly situated employees of the Company.

2.5Vacation/Paid Time Off. Executive will be entitled to twenty-two days of paid vacation per calendar year, subject to the Company’s vacation policy in effect from time to time. The Company may, at its discretion, increase (but not decrease) Executive’s vacation entitlement.

ARTICLE III

TERMINATION OF EMPLOYMENT

3.1Voluntary Resignation. Executive may terminate his employment for any reason by giving the Company 30 days’ prior written notice of a voluntary resignation date (“Resignation Date”). Upon receiving Executive’s notice of intent to resign, the Company may require that Executive cease performing services for the Company at any time before the Resignation Date, so long as the Company continues Executive’s Base Salary under Section 2.1 and employee benefits under Section 2.4 through the Resignation Date. Except as otherwise provided under law or the terms of any employee benefit plans in which Executive participates, Executive shall not be entitled to receive any compensation or benefits from the Company after the Resignation Date.

3.2Termination By Company With Cause. The Company may terminate Executive’s employment for Cause (as defined below) by giving written notice to Executive designating an immediate or future termination date. In the event of a termination for Cause, the Company shall pay Executive his

2

Base Salary under Section 2.1 and employee benefits under Section 2.4 through the termination date. Except as otherwise provided under law or the terms of any employee benefit plans in which Executive participates, Executive shall not be entitled to receive any compensation or benefits from the Company after the termination date.

For purposes of this Agreement, “Cause” means:

(a)A material breach by Executive of this Agreement;

(b)Executive commits an act constituting a felony or engages in unethical or immoral conduct that, in the reasonable judgment of the Board, could injure the integrity, character or reputation of the Company;

(c)The conviction, plea of no contest or nolo contendere, deferred adjudication or un- adjudicated probation of Executive for any felony or any crime involving moral turpitude; or

(d)Executive’s failure or refusal to carry out, or comply with, in any material respect, any lawful directive of the Chief Executive Officer (or Executive’s direct supervisor at the time) consistent with the terms of the Agreement, and with the Company’s written plans and policies, which is not remedied within 30 days after Executive’s receipt of written notice from the Company.

3.3Termination By Company Without Cause. The Company may terminate Executive’s employment without Cause by giving written notice to Executive designating an immediate or future termination date. Executive’s voluntary resignation of employment due to a material diminution of Executive’s authority, reporting line, duties or responsibilities shall be treated as a termination by Company without Cause; provided that, (a) such voluntary resignation occurs within 65 days following the initial occurrence of such diminution, (b) Executive provided written notice of such diminution to the Board and the Chief Executive Officer within 30 days of such diminution, and (c) the Company failed to cure such diminution within 30 days of receipt of such written notice from Executive.

In the event of a termination without Cause, Executive shall receive from the Company his Base Salary under Section 2.1 and employee benefits under Section 2.4 through the termination date, and shall be eligible to receive the benefits described in Sections 3.3(a) and (b), below (collectively, “Severance Pay”), subject to the requirements set forth in Section 3.6 and Section 3.7. The period over which the amounts in Section 3.3(a) are payable is referred to as the “Severance Period.”

(a)If Executive is terminated without Cause, the Company will provide the following compensation and benefits to Executive:

(i)A payment equal to 12 months of Executive’s then current Base Salary, less applicable withholdings. This amount will be paid in equal installments on each regularly scheduled payroll pay date during the 12 month period that begins on the Termination Date, subject to Section 3.6.

(ii)The pro rata portion of the target annual bonus and the Supplemental Savings Plan benefits earned through the Termination Date. Such amounts will be paid when all other Company executives receive such payments, but in no event later than March 15 of the year following the Termination Date.

(iii)Provided that timely elects continuation of group health plan coverage under the Consolidated Omnibus Budget Reconciliation Act of 1986, as amended (“COBRA”), the Company will provide a COBRA premium subsidy through the Severance Period (“COBRA Premium

3

Subsidy”). During the Severance Period, Executive will be required to pay only the unsubsidized portion of the COBRA premium (i.e., the full monthly COBRA premium minus the monthly COBRA Premium Subsidy). To qualify Executive for the COBRA Premium Subsidy, Employee must timely pay the applicable unsubsidized COBRA premiums required to maintain coverage for Executive and any eligible dependents under COBRA. It is understood and agreed that the period of time during which Executive is eligible for the COBRA Premium Subsidy shall run concurrent with and be credited toward the continuation coverage period to which Executive would be entitled pursuant to COBRA. Notwithstanding the foregoing, Executive understands and agrees that the Company's obligation to provide the COBRA Premium Subsidy shall cease on the earliest of (i) the end of the Severance Period, (ii) the date on which Executive becomes eligible for group health coverage offered by another employer or (iii) the date on which Executive otherwise ceases to be eligible for COBRA. Executive further understands and agrees that all other provisions of Executive’s (and Executive’s covered eligible dependents’) COBRA coverage (including, without limitation, any applicable co-payments, deductibles and other out-of-pocket expenses) will be in accordance with the applicable plan in effect for similarly situated active employees, as applicable. Executive also understands and agrees that the amount of the COBRA Premium Subsidy may be included in Executive’s taxable income and subject to applicable tax withholdings and required deductions from any severance payments. After the Severance Period expires, Executive will be required to timely pay the full monthly COBRA premium to continue COBRA coverage for any additional COBRA coverage period for which Employee or Employee’s eligible dependents are eligible.

(iv)During the twelve (12) month period immediately following the Termination Date, the Company shall treat Employee as if he/she were a continuing employee for purposes of applying the age and vesting provisions of unvested performance or non-performance based equity awards, measured from the date of Employee’s termination of employment. For the avoidance of doubt, the vesting and delivery of any such awards that are earned by Employee as a result of such continued vesting credit shall occur at the normally scheduled vesting date as specified in the underlying equity award agreement.

(v)The Company will pay for and provide to Executive outplacement services with an outplacement firm of Executive’s choosing, provided that the Company shall not be responsible to pay for such services to the extent such services (aa) exceed $15,000 or (bb) are provided more than one year following the Release Effective Date (as defined below).

(b)Not Used.

Except as otherwise provided under law or the terms of any employee benefit plans in which Executive participates, Executive shall not be entitled to receive any additional compensation or benefits from the Company after the termination date. All Severance Pay paid to Executive will be subject to the terms of the Company’s policy for recovering overpayments of incentive compensation in certain circumstances, including a restatement of reported financial or operating results, fraud or misconduct, in effect from time to time.

3.4Change in Control. If, contemporaneous with or within twelve months after a Change in Control (as defined below), the Company terminates Executive’s employment other than for Cause, Executive will be eligible to receive, in lieu of those payments provided under Section 3.3, as  applicable: (a) one and one-quarter (1¼) times Executive’s then current Base Salary; and (b) an amount equal to Executive’s target annual bonus for the year that includes the Termination Date (together, the “Change in Control Payment”), subject to the requirements set forth in Section 3.6. The Change in Control Payment will be made in a lump sum cash payment as soon as practicable, but in no event more than 10 days after

4

the Release Effective Date (as defined below) (on or after the date of the Change in Control). Executive shall also receive full, accelerated vesting credit, on the date of the Release Effective Date (as defined below), for any outstanding unvested equity awards (excluding performance-based equity awards, for which vesting credit may be awarded at the sole discretion of the Corporation’s Compensation Committee), consistent with and subject to the limitations of Section 3.7. In addition, Executive will be eligible for the continued health plan coverage described in Section 3.3(a)(ii).

For purposes of this Agreement, a “Change in Control” of the Corporation will be deemed to occur as of the first day that any one or more of the following conditions is satisfied:

(i)The “beneficial ownership” (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of securities representing 30% or more of the combined voting power of the then outstanding voting securities of the Corporation entitled to vote generally in the election of directors (the “Corporation Voting Securities”) is accumulated, held or acquired by a Person (as defined in Section 3(a)(9) of the Exchange Act, as modified, and used in Sections 13(d) and 14(d) thereof) (other than the Corporation, any trustee or other fiduciary holding securities under an employee benefit plan of the Corporation, holders of capital stock of the Corporation as of the date hereof or an affiliate thereof, any corporation owned, directly or indirectly, by the Corporation’s stockholders in substantially the same proportions as their ownership of stock of the Corporation); provided, however that any acquisition from the Corporation or any acquisition pursuant to a transaction that complies with clauses (A), (B) and (C) of subparagraph (iii) of this paragraph will not be a Change in Control under this subparagraph (i), and provided further, that immediately prior to such accumulation, holding or acquisition, such Person was not a direct or indirect beneficial owner of 25% or more of the Corporation Voting Securities; or

(ii)Within any twelve (12) month period that includes or is after the Start Date, individuals who constitute the Board (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board; provided, however, that any individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Corporation’s stockholders, was approved by a vote of at least a majority of the directors then comprising the Incumbent Board will be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board; or

(iii)Consummation by the Corporation of a reorganization, merger or consolidation, or sale or other disposition of all or substantially all of the assets of the Corporation or the acquisition of assets or stock of another entity (a “Business Combination”), in each case, unless immediately following such Business Combination: (A) more than 60% of the combined voting power of then outstanding voting securities entitled to vote generally in the election of directors of (x) the corporation resulting from such Business Combination (the “Surviving Corporation”), or (y) if applicable, a corporation that as a result of such transaction owns the Corporation or all or substantially all of the Corporation’s assets either directly or through one or more subsidiaries (the ‘‘Parent Corporation”), is represented, directly or indirectly by Corporation Voting Securities outstanding immediately prior to such Business Combination (or, if applicable, is represented by shares into which such Corporation Voting Securities were converted pursuant to such Business Combination), and such voting power among the holders thereof is in substantially the same proportions as their ownership, immediately prior to such Business Combination, of the Corporation Voting Securities; (B) no Person (excluding any employee benefit plan (or related trust) of the Corporation or such corporation resulting from such Business Combination) beneficially owns, directly or indirectly, 20% or more of the combined voting power of the then outstanding voting securities eligible to elect directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) except to the extent that such ownership of the Corporation existed prior to the Business Combination; and (C) at

5

least a majority of the members of the board of directors of the Parent Corporation (or, if there is no Parent Corporation, the Surviving Corporation) were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such Business Combination; or

(iv)Approval by the Corporation’s stockholders of a complete liquidation or dissolution of the Corporation.

However, in no event will a Change in Control be deemed to have occurred with respect to Executive if Executive is part of a purchasing group that consummates the Change in Control transaction. Executive will be deemed “part of a purchasing group” for purposes of the preceding sentence if Executive is an equity participant in the purchasing company or group (except: (a) passive ownership of less than two percent of the stock of the purchasing company; or (b) ownership of equity participation in the purchasing company or group that is otherwise not significant, as determined prior to the Change in Control by a majority of the nonemployee continuing Directors; provided that, for purposes of the foregoing, participation as a management investor in such purchasing company will not be deemed to be within the exceptions provided for in (a) and (b)).

Notwithstanding anything to contrary, a Change in Control will have occurred only if such change in ownership constitutes a change in control under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations and other guidance in effect thereunder (“Section 409A”).

3.5.Non-Renewal. For the avoidance of doubt, either party’s provision of written notice to the other party of intent not to renew this Agreement pursuant to Section 1.1, above, shall not be deemed a termination without Cause under Section 3.3, and in such a case, Executive shall be entitled to receive no compensation or benefits from the Company after Executive’s termination date except as otherwise provided in this paragraph, under law, or the terms of any employee benefit plans in which Executive participates. Notwithstanding the foregoing, in the event the Company elects not to renew the Agreement and Executive is terminated without Cause (to include a qualifying voluntary resignation due to material diminution of Employee’s authority duties or responsibilities, as set forth in Section 3.3) within twelve (12) months immediately following the end of the Employment Term, as defined in this Agreement, then during the remaining period of vesting, Company shall treat Employee as if he/she were a continuing employee for purposes of applying the age and vesting provisions of all unvested performance or non-performance based equity awards, measured from the date of Employee’s termination of employment, subject to the requirements set forth in Section 3.6. For the avoidance of doubt, the vesting and delivery of any such awards that are earned by Employee as a result of such continued vesting credit shall occur at the normally scheduled vesting date as specified in the underlying equity award agreement.

3.6Execution of Separation Agreement. As a condition to receiving the Severance Pay or the Change in Control Payment set forth in Section 3.3 or Section 3.4, respectively, Executive must execute and return to the Company, and not revoke any part of, a separation agreement containing a general release and waiver of claims against the Company and its respective officers, directors, stockholders, employees and affiliates with respect to Executive’s employment, and other customary terms, in a form and substance reasonably acceptable to the Company.  The Company shall deliver to Executive such release within ten (10) days following Executive’s termination of employment and Executive shall deliver an original, signed release to the Company within twenty-one (21) days of receipt thereof (or such longer period as may be required by applicable law to constitute an effective release of all claims, but no longer than 45 days after the after receipt of the same from the Company) (the “Release Deadline”). Notwithstanding anything in this Agreement to the contrary, no payments pursuant to Section 3.3 or Section 3.4 shall be made prior to the date that both (a) Executive has delivered an original, signed release to the Company and (b) the revocability period (if any) has elapsed without Employee having exercised Employee’s revocation rights (the “Release Effective Date”). Any payments that would otherwise be made during the first sixty (60)

6

days following Executive’s termination of employment will be made on the 65th day following Employee’s termination of employment. If Executive does not deliver an original, signed release to the Company by the Release Deadline, (i) Executive’s rights shall be limited to those made available to Executive under Section 3.1 above, and (ii) the Company shall have no obligation to pay or provide to Executive any amount or benefits described in Section 3.3 or Section 3.4, or any other monies on account of the termination of Executive’s employment.  Any obligation of the Company to provide the Severance Pay shall cease: (A) upon Executive’s death; (B) if Executive materially breached or breaches Executive’s contractual obligations to the Company, including those set forth in Article IV or Article V herein, or in the release agreement; or (C) if, after Executive’s termination, the Company discovers facts and circumstances that would have justified a termination for Cause.

3.7Section 409A. While the parties acknowledge that any payments and benefits provided under Article III of this Agreement are intended to be exempt from Section 409A, to the extent (a) further guidance or interpretation is issued by the IRS after the date of this Agreement which would indicate that the payments do not qualify for such exemption or the amount of payments due under Article III increases in a manner to cause certain payments to exceed the limitation available for exempt separation payment and (b) Executive is a “specified employee” within the meaning of Code Section 409A(a)(2)(B)(i) upon the date of Executive’s termination of employment, such payments or benefits which are not exempt and would otherwise be payable to Executive prior to the date that is six (6) months following the date of such termination of employment shall be delayed and instead shall be paid to Executive on the first regular payroll date that occurs after the six (6) month anniversary of such date of termination. For purposes of Section 409A, each installment of Severance Pay under Article III shall be treated as a right to a separate payment.

3.8Excess Parachute Payments. Notwithstanding any provision of this Agreement to the contrary, if any amount or benefit to be paid or provided under this Agreement would be an “Excess Parachute Payment” within the meaning of Code Section 280G but for the application of this sentence, then the payments and benefits to be paid or provided under this Agreement will be reduced to the minimum extent necessary (but in no event to less than zero) so that no portion of any such payment or benefit, as so reduced, constitutes an Excess Parachute Payment; provided, however, that the foregoing reduction will be made only if and to the extent that such reduction would result in an increase in the aggregate payment and benefits to be provided to Executive, determined on an after-tax basis (taking into account the excise tax imposed pursuant to Code Section 4999, any tax imposed by any comparable provision of state law, and any applicable federal, state and local income and employment taxes).

The fact that Executive’s right to payments or benefits may be reduced by reason of the limitations contained in this Section 3.8 will not of itself limit or otherwise affect any other rights of Executive other than pursuant to this Agreement. In the event that any payment or benefit intended to be provided under this Agreement is required to be reduced pursuant to this Section 3.8, the reduction shall be made in the following order: (a) first reducing, if any, those payments or benefits which have a higher Parachute Value than actual present value, (b) then, to the extent necessary, reducing cash payments or benefits; and (c) then, to the extent necessary, reducing those payments or benefits having the next highest ratio of Parachute Value to actual present value of such payments or benefits as of the date of the change of control (as defined under Code Section 280G). For purposes of this Section 3.8, present value shall be determined in accordance with Section 280G(d)(4) of the Code. For purposes of this Section 3.8, the “Parachute Value” of a payment or benefit means the present value as of the date of the change of control of the portion of such payment that constitutes a “parachute payment” under Section 280G(b)(2) of the Code, as valued in accordance with Section 280G of the Code any interpretive guidance thereunder.

3.9Removal from any Boards and Positions. If Executive’s employment is terminated for any reason under this Agreement, Executive will, immediately upon Executive’s termination of

7

employment, be deemed to have resigned from (a) if a member, the Board as well as the board of directors of any GLDD Entity (as defined below) or any other board to which Executive has been appointed or nominated by or on behalf of the Company, (b) any position with the Company or any GLDD Entity, including, but not limited to, as an officer of the Company or any GLDD Entity, and (c) any fiduciary positions with respect to the Company’s benefit plans. In addition, and as a condition to receiving the Severance Pay described in Section 3.3 or the Change in Control Payment described in Section 3.4, Executive shall take any and all necessary steps to effectuate Executive’s resignation from such positions.

ARTICLE IV

EXCLUSIVITY OF SERVICES AND RESTRICTIVE COVENANTS

4.1Confidential Information. Executive acknowledges and agrees that the Confidential Information (as defined below) of the Company and its subsidiaries and any other entity related to the Company (each, a “GLDD Entity”) that Executive obtained during the course of Executive’s employment by the Company is the property of the Company or such other GLDD Entity. Executive will never, directly or indirectly, disclose, publish or use any Confidential Information of which Executive has become aware, whether or not such information was developed by Executive. All duties and obligations set forth in this Agreement regarding Confidential Information shall be in addition to those which exist under the Illinois Trade Secrets Act and at common law.

As used in this Agreement, “Confidential Information” means information that is not generally known to the public and that was or is used, developed or obtained by the Company or any other GLDD Entity, in connection with its businesses, including but not limited to:

i. products or services, unannounced products or services, product or service development information (or other proprietary product or service information);

ii. fees, costs, bids and pricing structures and quotations or proposals given to agents, customers, sureties, suppliers, or prospective customers, agents, sureties or suppliers, or received from any such person or entity;

iii. accounting or financial records;

iv. strategic business plans;

v. information system applications or strategies;

vi. customer and vendor lists and employee lists and directories;

vii. marketing plans, bidding strategies and processes, and negotiation strategies, whether past, current, or future;

viii. accounting and business methods;

ix. legal advice and/or attorney work product;

x. trade secrets and other proprietary information;

xi. information, analysis or strategies regarding acquisitions, mergers, other business combinations, divestitures, recapitalizations, or new ventures; and

8

xii. nonpublic information that was acquired by Executive concerning the requirements and specifications of the Company’s or any other GLDD Entity’s agents, vendors, contractors, customers, or potential customers.

Notwithstanding anything to the contrary, Confidential Information does not include any information that: (a) is publicly disclosed by law or pursuant to, and to the extent required by, an order of a court of competent jurisdiction or governmental agency; (b) becomes publicly available through no fault of Executive; or (c) has been published in a form generally available to the public before Executive proposes to disclose, publish, or use such information.

4.2Noncompetition. During the Employment Term and for the twelve (12) month period immediately following the termination of Executive’s employment with the Company for any reason (the “Restricted Period”), Executive will not, on behalf of himself or any other entity, have an ownership interest in or become employed or engaged by, or otherwise participate in or render services to, any business or enterprise (including, without limitation, any division, group or franchise of a larger organization) within the Geographical Area (as defined below) that engages in any dredging, land reclamation or any other business engaged in by the Company; provided, however, that this restriction shall not prohibit Executive from passive beneficial ownership of less than three percent of any class of securities of a publicly-held corporation whose stock is traded on a U.S. national securities exchange or traded in the over-the-counter market. For the purpose of this provision, “Geographical Area” means any continent where the Company has conducted operations during the eighteen (18) month period immediately preceding the Termination Date. Notwithstanding anything in this Article IV to the contrary, Executive may, at any time during the Restricted Period, provide written notice to the Company that (i) describes a particular business or employment opportunity that Executive is interested in pursuing or in which Executive may wish to engage, and (ii) request that the Company agree that the opportunity so described would not violate this Section 4.2. Within a reasonable time, the Company will send Executive a written response, indicating whether or not the Company consents to Executive engaging in the opportunity described in Executive’s notice.

4.3Non-Solicitation. During the Restricted Period, Executive shall not (other than in furtherance of Executive’s legitimate job duties on behalf of Company), directly or indirectly, on Executive’s own behalf or for any other person or entity: (a) solicit for employment, hire or engage, or attempt to solicit for employment, hire or engage, any person who is or was employed by the Company within the six (6) month period prior to the solicitation, hire or engagement, or (b) otherwise interfere with the relationship between any such person and the Company.

4.4Non-Interference with Business Relationships. During the Restricted Period, Executive shall not (other than in furtherance of Executive’s legitimate job duties on behalf of the Company), directly or indirectly, on Executive’s own behalf or for any other person or entity: (a) solicit, for a purpose related to a competitive activity (i.e., an activity prohibited by Section 4.2), any customer, vendor or agent of the Company that was doing business with the Company during the six month period prior to the solicitation; or (b) induce, or attempt to induce, any customer, vendor or agent of the Company to reduce or cease doing business with the Company, or otherwise interfere with the relationship between such entity and the Company.

4.5Equitable Modification. If any court of competent jurisdiction shall deem any provision in this Article IV too restrictive, the other provisions shall stand, and the court shall modify the unduly restrictive provision to the point of greatest restriction permissible by law.

4.6Remedies. Executive acknowledges that the agreements and covenants contained in this Article IV are essential to protect the Company and its business and are a condition precedent to entering into this Agreement. Should Executive breach any covenants in this Article IV, then among other remedies,

9

the duration of the covenant shall be extended by the period of any such breach. Executive agrees that irreparable harm would result from Executive’s breach or threat to breach any provision of this Article IV, and that monetary damages alone would not provide adequate relief to the Company for the harm incurred. Executive agrees that in addition to money damages, the Company shall be entitled to seek and obtain temporary, preliminary, and permanent injunctive relief restraining Executive from committing or continuing any breach without being required to post a bond. Without limiting the foregoing, upon a breach by Executive of any provision of this Article IV, any outstanding Severance Pay shall cease and be forfeited, and Executive shall immediately reimburse the Company for any Severance Pay previously paid.

ARTICLE V

5.1Return of Company Materials. No later than three (3) business days following the termination of Executive’s employment for any reason, Executive shall return to the Company all Company property that is then in Executive’s possession, custody or control, including, without limitation, all keys, access cards, credit cards, computer hardware and software, documents, records, policies, marketing information, design information, specifications and plans, data base information and lists, and any other property or information that Executive has or had relating to the Company (whether those materials are in paper or computer-stored form), and including but not limited to any documents containing, summarizing, or describing any Confidential Information. Executive shall be entitled to retain Executive’s cellular telephone and cellular telephone number.

The Company shall reimburse Employee for all reasonable out-of-pocket expenses incurred by Employee in fulfilling Employee’s obligations under this Section 5.2. The Company will make any such reimbursement within 30 days of the date Employee provides the Company with documentary evidence of such expense consistent with the policies of the Company. Notwithstanding anything to the contrary, any such reimbursement shall be administered so as to comply with Treasury Regulation Section 1.409A-3(i)(1)(iv).
