 THIS SEVERANCE
AGREEMENT (this “Agreement”) is made and entered into by and between Rubicon Technology, Inc., a Delaware corporation (the “Company”) and Hap R. Hewes (“Executive”) as of September 8, 2005 (the “Effective
Date”). 
 WHEREAS, it is in the best interests of the Company and the Company’s stockholders to assure Executive’s continued
dedication to the Company; and 
 WHEREAS, it is in the best interests of the Company and the Company’s stockholders to retain
Executive’s dedication by providing Executive with compensation and benefits arrangements in the event of certain terminations of Executive’s employment, as more fully provided herein; 
 NOW, THEREFORE, in consideration of and reliance upon the foregoing and the covenants contained in this Agreement, and other good and valuable
consideration, the receipt and sufficiency of which is hereby acknowledged, the Company and Executive agree as follows: 
 1. DEFINITIONS 

1.1 “Cause” shall mean any of the following: (i) Executive’s commission of a willful act (including, without limitation, a
dishonest or fraudulent act) or a grossly negligent act, or the willful or grossly negligent omission to act by Executive, which is intended to cause, causes or is reasonably likely to cause material harm to the Company or any of its subsidiaries
(including harm to the business reputation of the Company or any of its subsidiaries); (ii) Executive’s commission or conviction of, or plea of nolo contendere to, any felony or any crime or offense involving dishonesty or fraud or
that is significantly injurious to the Company or any of its subsidiaries (including harm to the business reputation of the Company or any of its subsidiaries); (iii) Executive’s breach of any material term or covenant of any agreement
with the Company or any of its subsidiaries that, if capable of being cured, remains uncured for thirty (30) days following written notice of such breach from the Company to Executive (unless such agreement provides for a longer cure period in
which case such longer cure period shall apply); (iv) Executive’s willful neglect of or continued failure to substantially perform, in any material respect, his or her duties (as assigned to Executive from time to time) or obligations
(including a violation of policy) to the Company or any of its subsidiaries, which neglect or failure continues for thirty (30) days following written notice thereof from the Company to Executive; or (v) Executive’s use or abuse of
illegal drugs or other controlled substances at any time or Executive being under the influence of alcohol or being affected by the use of alcohol during any time period in which he or she is required to perform his or her duties and obligations to
the Company. 
 1.2 “Good Reason” shall mean any one of the following events, without Executive’s written consent:

 Confidential 
 duties or responsibilities; (ii) a breach by the Company of any material term or covenant of any agreement with Executive that, if capable of being cured, remains uncured for thirty (30) days following written notice of such
breach from Executive to the Company (unless such agreement provides for a longer cure period in which case such longer cure period shall apply); (iii) a requirement that Executive be based at any office or location that is more than
seventy-five (75) miles from the Executive’s principal office location; or (iv) a failure by any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all or substantially all of the business or
assets of the Company to assume expressly and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession had taken place. Executive must provide the Company
written notice of any claim of Good Reason within ninety (90) days after the occurrence of any action/inaction giving rise to such claim, and the Company or its Affiliate will have thirty (30) days to cure such claim (or such longer period
as may be provided under clause (ii) of the immediately preceding sentence). 
 2. TERMINATIONS OF EMPLOYMENT TRIGGERING SEVERANCE BENEFITS

 2.1 Subject to Section 2.2, and provided that Executive has executed a full and complete release of the Company and its
subsidiaries (and their related parties) from any and all claims, in a form prepared by the Company, the Company will provide Executive with the benefits set forth in Section 3 if Executive’s employment is terminated for the following
reasons (“Qualifying Terminations”): (i) by the Company without Cause at any time; or (ii) by Executive for Good Reason at any time. 
 2.2 In no event will benefits be payable to Executive under this Agreement in the event of termination due to Executive’s death, disability, retirement, termination by the Company for Cause, or voluntary
termination by Executive without Good Reason. 
 3. TERMINATION BENEFITS. 
 3.1 Subject to the conditions set forth in Section 2, the following benefits shall be paid or provided to Executive in the event Executive’s
employment is terminated and the termination is a Qualifying Termination: 
 (a) Cash Severance. The Company shall pay
to Executive six months’ of Executive’s annualized base salary in effect at the Qualifying Termination, payable in accordance with the Company’s standard payroll practices over the six month period following the date of the Qualifying
Termination. 
 (b) Health Benefits. To the extent permissible under applicable law, the Company shall continue to
provide coverage to Executive (and to Executive’s spouse and dependents who are covered as of date of the Qualifying Termination) under the health benefit plans the Company maintains for active employees following Executive’s Qualifying
Termination, at the same cost to Executive and under the same terms applicable to active employees (and their dependents), for a period of twelve months after Executive’s Qualifying Termination. Notwithstanding the foregoing, if Executive
becomes employed with another employer during such twelve month period and is eligible to receive substantially comparable health benefits from such employer, the 
  

					
	 RUBICON TECHNOLOGY, INC.
	  	-2-	  	SEVERANCE AGREEMENT

 Confidential 
 obligation of the Company to provide the benefits described in this Section 3.1(b) shall cease. Executive hereby authorizes the Company to make appropriate deductions from the severance payable hereunder for the
Executive’s cost portion with respect to such continued health benefits. 
 (c) Option Expirations and Vesting.
The period during which Executive is permitted to exercise any vested portions of each option award under the Rubicon Technology, Inc. 2001 Equity Plan, as heretofore or hereafter amended, or any similar or successor plan, held by Executive on the
date of the Qualifying Termination, shall be extended until the second anniversary of the date of the Qualifying Termination or any earlier expiration of the term of such option. Additionally, if any portion of an option is subject to vesting and
more than one-half of the then current vesting period has elapsed on the date of the Qualifying Termination, then with respect to that portion of the option, the vesting of such award shall be accelerated as if the Qualifying Termination had
occurred on the last day of the option vesting period during which the Qualifying Termination had occurred (such that, by way of example, if the date of a Qualifying Termination occurs during the second half of the second year of an option that
vests over four one-year periods, the vesting of such option shall be accelerated as if the Qualifying Termination had occurred on the last day of the second year of vesting, but if the Qualifying Termination occurs during the first month of the
second year of such option, then the vesting shall not be accelerated). 
 (d) Performance Bonus. The Company shall pay
to Executive a bonus equal to two times the “Minimum Bonus” (as such term is used in the Rubicon Technology, Inc. 2005 Performance Bonus Plan) that Executive would otherwise be entitled to under such plan but for the Qualifying
Termination. The foregoing amount shall be payable at the same time and in the same manner as bonuses are payable under the Rubicon Technology, Inc. 2005 Performance Bonus Plan. 
 3.2 Taxation and Withholding. The Company does not make any representations or warranties with respect to, and has no responsibility or liability
for, the personal tax consequences of this Agreement to Executive. The Company may make such provisions and take such steps as it may deem necessary or appropriate for the withholding of any taxes that the Company is required by any law or
regulation of any governmental authority, whether federal, state or local, domestic or foreign, to withhold in connection with this Agreement. 
 3.4 Executive’s Death. If Executive dies before the completion of any payments or benefits required under the Section 3, the Company will make or continue payments and benefits to Executive’s surviving spouse, if any,
or Executive’s estate in accordance with this Section. 
 4. MISCELLANEOUS 
 4.1 Employment Status. Nothing herein shall be deemed to create any term of employment, it being expressly understood and agreed between the
parties that Executive’s employment is at will and that either party may terminate such employment at any time. 
 4.2 Governing
Law. All provisions of this Agreement will be construed and governed by Illinois law without regard to its choice of law principles or the laws of any other 
  

					
	 RUBICON TECHNOLOGY, INC.
	  	-3-	  	SEVERANCE AGREEMENT

 Confidential 
 jurisdiction. Any suit, claim or other legal proceeding arising out of or relating to Executive’s employment, his or her termination from employment, or this Agreement shall be brought exclusively in the federal or state courts located
in Cook County, Illinois, and Executive and the Company hereby submit to personal jurisdiction in the State of Illinois and to venue in such courts. Notwithstanding the foregoing, the Company may seek and obtain injunctive relief against Executive
in any court having jurisdiction over Executive. 
 4.3 Severability. Every provision of this Agreement is intended to be severable.
If any provision or portion of a provision is illegal or invalid, then the remainder of this Agreement shall not be affected. Moreover, any provision of this Agreement which is determined to be unreasonable, arbitrary or against public policy shall
be modified as necessary so that it is not unreasonable, arbitrary or against public policy while maximizing the intent of the parties. 
 4.4 Entire Agreement. This Agreement constitutes the entire understanding of the parties with respect to payment of any severance benefits superseding all prior agreements, understandings, negotiations and discussions between them,
whether written or oral (including any portions of any employment agreements relating to the payment of any severance benefits) and as of the Effective Date, there are no other understandings, representations, warranties or commitments with respect
to payment of any severance benefits. 
 4.5 Successors and Assigns. This Agreement may not be assigned by Executive. This Agreement
shall be binding upon and inure to the benefit of all successors and assigns (whether by operation of law or otherwise) of the Company. 
 4.6 Amendment. This Agreement may only be amended or terminated by mutual written agreement between the Company and Executive. No modification, amendment or waiver of this Agreement or consent to any departure by Executive from any
of the terms or conditions thereof, shall be effective unless in writing and signed by the Chairman of the Board. 
 4.7 Counterparts.
The parties may execute this Agreement in one or more counterparts, all of which together shall constitute but one Agreement. 
 IN WITNESS
WHEREOF, each party has executed this Severance Agreement or caused this Severance Agreement to be duly executed as of the Effective Date.

 EXECUTIVE EMPLOYMENT AGREEMENT 
 THIS EXECUTIVE EMPLOYMENT AGREEMENT
(“Agreement”) is made and entered into as of July 30, 2007 (the “Effective Date”), by and between Rubicon Technology, Inc., a Delaware corporation (the “Company”), and William F. Weissman, a
resident of the State of Illinois (the “CFO”). 
 PRELIMINARY STATEMENTS 
 The Company is in the business of providing material science solutions of sapphire and other advanced technology materials for the Opto-electrics
Semiconductor Fabrication, Optical and Laser and Telecommunications Marketplaces (“Company’s Business”); provided, however, the term shall be deemed amended to reflect any actual change in the Company’s
Business after the date hereof but prior to the day following the date on which CFO shall cease to be employed by the Company (as reflected in the minutes of the Board of Directors of the Company prior to the Termination Date (as defined below) or
the Resignation Date (as defined below), as applicable). 
 The CFO has been employed on a part-time basis for approximately two
(2) months prior to the date hereof and will be employed by the Company and, as a result of such employment, has and will become acquainted with the affairs of the Company and its personnel, services, products, and business practices and
relationships and other Confidential Information (as defined in Section 5 below). This Agreement is entered into for, among other things, the protection of the Company’s business relationships, goodwill and going business value and
the prevention of the unauthorized use or disclosure of any Confidential Information by the CFO. 
 AGREEMENT 
 In consideration of the premises and the mutual promises and covenants contained in this Agreement and other good and valuable consideration, the receipt
and sufficiency of which is hereby acknowledged, the parties hereto agree as follows: 
 Section 1. Employment and Duties.

 (a) Employment Duties. Throughout the Employment Term (as defined in Section 2 below), the CFO shall
serve as Chief Financial Officer of the Company, and shall report to the Chief Executive Officer (“CEO”). Throughout the Employment Term, the CFO shall: (i) devote his working hours, on a full-time basis, to his duties and
responsibilities to the Company; (ii) faithfully and loyally serve the Company; (iii) comply in all material respects with all lawful directions and instructions given to him by the CEO and the Board of Directors of the Company (the
“Board”); and (iv) use his best efforts to promote and serve the interests of the Company. The CFO shall comply in all material respects with all applicable laws, rules and regulations relating to the performance of the
CFO’s duties and responsibilities hereunder. 
 (b) Exclusive Employment. Throughout the Employment Term, the CFO
shall not render his services, directly or indirectly, to any person or entity other than the 

  

 -1- 

 
Company without the prior consent of the Board, which may be withheld or granted by the Board in its sole discretion. The CFO shall not engage in any
activity which would materially interfere with the faithful and timely performance of his duties under this Agreement; provided, however, the CFO may, subject to the prior consent of the Board, which shall not be unreasonably withheld,
serve as a director of any other company, so long as such service does not unreasonably and materially interfere with the timely performance of the CFO’s duties under this Agreement. 
 Section 2. Employment Term. The CFO’s employment with the Company, pursuant to this Agreement, shall commence on July 30,
2007 and shall continue thereafter until June 30, 2008 (the “Initial Term”), unless otherwise terminated as provided herein. The Initial Term shall be automatically extended on a year-to-year basis thereafter (a
“Renewal Term”), unless a notice of non-renewal is given in writing by either party to the other party not less than sixty (60) days prior to the end of the Initial Term or any Renewal Term, as applicable. The CFO’s
employment by the Company shall be subject to termination at any time during or at the end of the Initial Term or any Renewal Term as provided in Section 4. As used herein, “Employment Term” shall mean the actual period
of time during which the CFO is employed by the Company under the terms and conditions of this Agreement. 
 Section 3.
Compensation and Other Benefits. During the Employment Term, the Company shall pay and provide the following compensation and other benefits to the CFO as full compensation for all services rendered by the CFO to the Company: 

(a) Annual Salary. In exchange for the CFO’s performance under the terms of this Agreement, the annual salary shall be Two
Hundred Thousand Dollars ($200,000) (the “Annual Salary”). The Annual Salary shall be paid in accordance with the then-prevailing payroll practices of the Company, less applicable taxes, payroll deductions and withholdings required
by law. The Company agrees that the Board shall review the Annual Salary on an annual basis and make appropriate adjustments thereto from time to time; provided that the Annual Salary shall not be reduced below $200,000 without the CFO’s
consent. 
 (b) Bonuses. The CFO shall be eligible to receive, at the sole discretion of the Board and the
Board-appointed Compensation Committee, an annual discretionary bonus from the Company of 25% of the Annual Salary; provided that, in the discretion of the Company, the bonus may be more or less than such targeted amount. This bonus shall be subject
to applicable taxes, payroll deductions and withholdings required by law. 
 (c) Stock Options. The CFO has previously
been granted, under the Rubicon Technology, Inc. 2001 Equity Plan (the “Plan”), a non-qualified option to purchase 200,000 common shares, par value $0.001 per share, of the Company (“Common Shares”) at a purchase
price of sixty-five cents ($.65) per share, which shall vest over four (4) years at 25% per year, provided that, upon consummation of the Company’s IPO or a Change of Control, such options shall automatically become fully vested and
exercisable, provided, however, that the CFO executes and delivers to the Company a complete release agreement in form and substance reasonably acceptable to the Company. In addition, the CFO is hereby granted, under the Plan, a
non-qualified option 

  

 -2- 

 
to purchase 2,474,531 Common Shares at a purchase price per Common Share of sixty-five cents ($.65), which shall vest in four (4) equal amounts on the
first day of August of each of the next four (4) calendar years; provided that, if the CFO’s employment is terminated by the Company without Cause (as hereafter defined) or by the CFO for Good Reason (as hereafter defined) these options
shall immediately be fully vested. Except as is expressly provided above, each of the options granted to the CFO shall be subject to the Plan and to the terms of the Company’s standard Option Agreement which shall be executed and delivered by
the parties promptly upon the execution hereof. All numbers of shares and “per share” amounts in this paragraph are subject to equitable adjustment to reflect any stock splits, combinations or recapitalization affecting the Common Shares,
including the Company’s proposed 1 for 13 reverse stock split on the Common Shares. 
 (d) Management Incentive
Plan. The CFO will be entitled to participate in the Company’s Management Incentive Plan (the “Incentive Plan”), but participation shall be subject to all of the terms and conditions of the Incentive Plan applicable to all
management of the Company, including all waiting periods, eligibility requirements, exclusions and other similar conditions or limitations. Under the Incentive Plan, the CFO shall be entitled to receive one-half of one percent (.5%) of the Sales
Proceeds, as defined therein, which allocation may be increased as provided in the Incentive Plan from time to time. 
 (e)
Employee Benefit Plans. The CFO shall be eligible to participate in all employee benefit plans offered by the Company, but participation shall be subject to all of the terms and conditions of such plans applicable to all such employees,
including all waiting periods, eligibility requirements, contributions, exclusions and other similar conditions or limitations. 
 (f) Vacation Leave. The CFO shall be entitled to twenty-one (21) calendar days of vacation leave per calendar year, prorated for any portion of a calendar year this Agreement is in effect, to be taken at such times as mutually
agreed upon by the Board and the CFO. The CFO shall accrue and receive full compensation and benefits during his vacation leave periods. Unused vacation time shall not entitle the CFO to any additional compensation. 
 (g) Other Expenses. The Company shall reimburse the CFO for all reasonable and ordinary out-of-pocket business expenses incurred by
the CFO in the scope of his employment hereunder. The CFO shall submit itemized expense reports in order to obtain reimbursement of expenses and shall submit with such expense reports such records and logs as may be required by the relevant taxing
authorities for the substantiation of each such business expense as a deduction on the Company’s income tax returns. 
 Section 4. Termination of Employment. The CFO’s employment with the Company shall be subject to termination as follows: 
 (a) Termination for Cause. The Company may immediately terminate the CFO for Cause (as defined below) by giving written notice to the CFO. In the event of a 

  

 -3- 

 
termination for Cause, the CFO shall be entitled to payment of that portion of any of CFO’s Annual Salary that the CFO earned through and including the
Termination Date, at the rate of the Annual Salary in effect at that time, and any bonus declared prior to the Termination Date that remains unpaid, subject to any offset or recoupment rights of the Company and any other rights or remedies
applicable to any breach of this Agreement by the CFO prior to the Termination Date. Except as provided herein or required by applicable law, the CFO shall not be entitled to any other compensation or benefits. Termination for
“Cause” shall mean termination by the Board of the CFO’s employment with the Company, after a good faith determination by the Board at a meeting called and held for that purpose, or in a written consent to resolutions signed by
all members of the Board, and after reasonable notice to the CFO, that the CFO: 
 (i) has willfully engaged in misconduct
materially and adversely affecting the Company; 
 (ii) engaged in theft, fraud, embezzlement or similar behavior; 

(iii) has been indicted or convicted of a felony; or 
 (iv) has willfully continued, after a correction period, to fail to substantially perform the material duties of CFO’s position with
the Company (other than failure resulting from incapacity due to physical or mental illness). The correction period shall last not less than ten (10) days after the Company provides CFO with written notice of CFO’s failure to substantially
perform CFO’s material duties. 
 (b) Termination Without Cause. The Company may, in its sole discretion,
terminate the CFO without Cause, by providing written notice to the CFO (the “Termination Notice”) at least thirty (30) calendar days prior to the Termination Date. In the event of a termination without Cause, the CFO shall be
entitled to: (i) payment of that portion of any CFO’s Annual Salary that the CFO earned through and including the Termination Date, at the rate of the Annual Salary in effect at that time; (ii) any bonus declared prior to the
Termination Date that remains unpaid; (iii) payment of that portion of CFO’s Annual Salary, at the rate of the Annual Salary in effect at that time, commencing on the Termination Date and continuing for the six-month period thereafter; and
(iv) accelerated vesting of the Option pursuant to Section 3(c); provided, however, that the CFO executes and delivers to the Company a complete release agreement in form and substance reasonably acceptable to the
Company. In addition, the Company shall be obligated to continue any health and welfare benefits provided to the Executive under Section 3(e) throughout the period commencing on the Termination Date and continuing for a six-month period
thereafter. Except as provided herein or required by applicable law, the CFO shall not be entitled to any other compensation or benefits. With respect to Section 4(b)(iii) above, such payments shall be paid in accordance with the
then-prevailing payroll practices of the Company, less applicable taxes, payroll deductions and withholdings required by law. 
  

 -4- 

 (c) Termination Without Cause Post-IPO After Change in Control. In the event that
the Company, at any time after an IPO and within one (1) year after a Change in Control, terminates the CFO without Cause (as defined below), the CFO shall be entitled to a lump sum payment within thirty (30) days of termination equal to
six (6) months of the CFO’s base pay, less applicable taxes, payroll deductions and withholdings required by law, provided, however, that the CFO executes and delivers to the Company a complete release agreement in form and
substance reasonably acceptable to the Company. Notwithstanding the preceding sentence, if the independent accountants acting as auditors for the Company on the date of the Change in Control determine that such single payment, together with other
compensation received by the CFO, would constitute “excess parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended, and regulations thereunder, the single payment to the CFO shall be
reduced to the maximum amount which may be paid without such payments in the aggregate constituting “excess parachute payments”. 
 (d) Resignation. The CFO may resign from his employment with the Company at any time by providing written notice to the Company thirty (30) calendar days prior to the Resignation Date. In the event of
resignation, the CFO shall be entitled to payment of that portion of the CFO’s Annual Salary that the CFO earned through and including the Resignation Date, at the rate of the Annual Salary in effect at that time, and any bonus declared by the
Board prior to the Resignation Date that remains unpaid. Except as provided herein (including, without limitation, in Section 4(d)) or required by applicable law, the CFO shall not be entitled to any other compensation or benefits.

 (e) Resignation for Good Reason. Notwithstanding Section 4(c), the CFO may terminate his employment by
the Company for Good Reason (as defined below) by providing written notice thereof to the Company (the “Resignation Notice”) at least thirty (30) days prior to the Resignation Date, which notice shall set forth in reasonable
detail the nature of the facts and circumstances which constitute Good Reason and Company shall have thirty (30) days after receipt of the Resignation Notice to cure in all material respects the facts and circumstances which constitute Good
Reason. In the event of a termination for Good Reason, the CFO shall be entitled to: (i) payment of that portion of the CFO’s Annual Salary that the CFO earned through and including the Resignation Date, at the rate of the Annual Salary in
effect at that time; (ii) any bonus declared prior to the Resignation Date that remains unpaid; (iii) payment of that portion of CFO’s Annual Salary, at the rate of the Annual Salary in effect at that time, commencing on the
Resignation Date and continuing for the six-month period thereafter; and (iv) accelerated vesting of the Option pursuant to Section 3(c); provided, however, that the CFO executes and delivers to the Company a complete
release agreement in form and substance reasonably acceptable to the Company. In addition, the Company shall be obligated to continue any health and welfare benefits provided to the Executive under Section 3(e) throughout the period
commencing on the Termination Date and continuing for a six-month period thereafter. Except as provided herein or required by applicable law, the CFO shall not be entitled to any other compensation or benefits. With respect to
Section 4(d)(iii) above, such payments shall be paid in accordance with the then-prevailing payroll practices of the Company, less applicable taxes, payroll deductions and withholdings required by law. For purposes of this Agreement,
“Good Reason” means 

  

 -5- 

 
the resignation of the CFO’s employment by the Company by the CFO, because of (A) any reduction in the CFO’s Annual Salary then in effect in a
manner that is not permitted under Section 3(a) hereof, (B) a substantial diminution in the duties, responsibilities or titles of the CFO, but only if uncured in accordance with the foregoing provisions hereof, or (C) being
required by the Board to relocate (for a period longer than six (6) consecutive months) greater than 100 miles from the Chicago, Illinois metropolitan area in order to maintain employment with the Company pursuant to this Agreement. 

(f) Death. If the CFO dies, his employment with the Company shall automatically terminate on the date of his death. The
CFO’s estate or personal representative shall be entitled to receive that portion of the Annual Salary that the CFO earned through and including the date of the CFO’s death, at the rate of the Annual Salary in effect at that time, and any
bonus declared prior to the date of the CFO’s death that remains unpaid. Except as provided herein or required by applicable law, neither the CFO’s estate nor his personal representative shall be entitled to any other compensation or
benefits. 
 (g) Disability. The CFO shall be deemed “Permanently Disabled” when he has suffered any
medically determinable physical or mental illness, injury or infirmity that prevents the CFO from performing his responsibilities under this Agreement and which disability has lasted or that the Board in good faith has determined can be expected to
last for a continuous period of not less than 120 calendar days. The Board has the discretion to determine whether the CFO is disabled and that determination shall be binding and conclusive on the CFO (and any guardians or representatives for him).
If the CFO becomes Permanently Disabled, the Company may terminate the CFO’s employment with the Company as a result of the Permanent Disability by providing written notice to the CFO thirty (30) calendar days prior to the Termination
Date, or the CFO may resign from his employment with the Company by providing written notice to the Company thirty (30) calendar days prior to the Resignation Date. If the CFO resigns from employment with the Company as a result of a Permanent
Disability or the Company terminates the CFO’s employment as a result of a Permanent Disability, the CFO shall be entitled to receive that portion of the Annual Salary, at the rate in effect when he became Permanently Disabled, that he earned
through and including the Termination Date or Resignation Date, as applicable, less any amounts the CFO is entitled to receive under any disability insurance policy maintained by the Company, and any bonus declared prior to the Termination
Date or Resignation Date, as applicable, that remains unpaid. Except as provided herein or required by applicable law, the CFO shall not be entitled to any other compensation or benefits. 
 Section 5. Confidentiality. For purposes of this Section 5, the term “Company” shall include, in addition
to the Company, its affiliates, subsidiaries and any of their respective predecessors, successors and assigns. 
 (a)
Confidential Information. As used in this Agreement, “Confidential Information” means any and all confidential, proprietary or other information, whether or not originated by the CFO or the Company, which is in any way
related to the past or present Company’s Business and is either designated as confidential or not generally 

  

 -6- 

 
known by or available to the public. Confidential Information includes, but is not limited to (whether or not reduced to writing or designated as
confidential) (i) information regarding the Company’s existing and potential customers and vendors; (ii) any contracts (including the existence and contents thereof and parties thereto) to which the Company is a party or is bound;
(iii) information regarding products and services being purchased or leased by or provided to the Company; (iv) information received by the Company from third parties under an obligation of confidentiality, restricted disclosure or
restricted use; (v) personnel and financial information of the Company; (vi) information with respect to the Company’s products, services, facilities, business methods, systems, trade secrets, technical know-how, and other
intellectual property; (vii) marketing and developmental plans and techniques, price and cost data, forecasts and forecast assumptions, and potential strategies of the Company; and (viii) any other information relating to the Company which
was obtained by the CFO in connection with his employment by the Company, whether before, on or after the Effective Date. 
 (b) Non-Disclosure and Non-Use of Confidential Information. The CFO acknowledges that the Confidential Information of the Company is a valuable, unique asset of the Company and the CFO’s unauthorized use or disclosure thereof
could cause irreparable harm to the Company for which no remedy at law could be adequate. Accordingly, the CFO agrees that he shall hold all Confidential Information of the Company in strict confidence and solely for the benefit of the Company, and
that, except as necessary in the course of CFO’s duties as an employee of the Company, he shall not, directly or indirectly, disclose or use or authorize any third party to disclose or use any Confidential Information. The CFO shall follow all
the Company policies and procedures to protect all Confidential Information and take any additional precautions necessary to preserve and protect the use or disclosure of any Confidential Information at all times. 
 (c) Ownership of Confidential Information. The CFO acknowledges and agrees that all Confidential Information is and shall remain
the exclusive property of the Company, whether or not prepared in whole or in part by the CFO and whether or not disclosed to or entrusted to the custody of the CFO. Upon the termination or resignation of his employment by the Company, or at any
other time at the request of the Company, the CFO shall promptly deliver to the Company all documents, tapes, disks, or other storage media and any other materials, and all copies thereof in whatever form, in the possession of the CFO pertaining to
the Company’s Business, including, but not limited to, any containing Confidential Information. 
 (d) Public
Information. Notwithstanding anything contained in this Agreement to the contrary, information which is generally available or accessible to the public shall be deemed Confidential Information of the Company if such information was retrieved,
gathered, assembled or maintained by the Company in such a manner not available to the public or for a purpose beneficial to the Company. From time to time, the Company may, for its own benefit, choose to place certain Confidential Information or
records of the Company in the public domain. Notwithstanding anything contained in this Agreement to the contrary, the fact that such Confidential Information may be made available to the public in a limited form and under limited circumstances does
not change 

  

 -7- 

 
the confidential and proprietary nature of such information, and does not release the CFO from his duties with respect to such Confidential Information as
set forth in this Agreement. 
 (e) Survival. The CFO’s obligations set forth in this Section 5, and
the Company’s rights and remedies with respect hereto, shall indefinitely survive the termination of this Agreement and the CFO’s employment by the Company, regardless of the reason therefor. 
 Section 6. Restrictive Covenants. For purposes of this Section 6, the term “Company” shall include, in
addition to the Company, its affiliates, subsidiaries and any of their respective predecessors, successors and assigns. 
 (a)

fair and reasonable in all respects to protect the legitimate interests of the Company and that these restrictions are designed for the reasonable protection of Company’s Business. 
 (b) Remedies. The CFO recognizes that any breach of this Agreement shall cause irreparable injury to the Company, inadequately

restraining order, preliminary injunction, or permanent injunction, in each case without notice or bond, against CFO to enforce this Agreement. The Company shall not be required to demonstrate actual injury or damage to obtain injunctive relief from
the courts. To the extent that any damages are calculable resulting from the breach of this Agreement, the Company shall also be entitled to recover damages, including, but not limited to, any lost profits of the Company and/or its affiliates or
subsidiaries. For purposes of this Agreement, lost profits of the Company shall be deemed to include all gross revenues resulting from any activity of the CFO in violation of this Agreement and all such revenues shall be held in trust for the
benefit of the Company. Any recovery of damages by the Company shall be in addition to and not in lieu of the injunctive relief to which the Company is entitled. In no event will a damage recovery be considered a penalty in liquidated damages. In
addition, in any action at law or in equity arising out of this Agreement, the prevailing party shall be entitled to recover, in addition to any damages caused by a breach of this Agreement, all costs and expenses, including, but not limited to,
reasonable attorneys’ fees, expenses, and court costs incurred by such party in connection with such action or proceeding. Without limiting the Company’s rights under this Section 7(b) or any other remedies of the Company, if a
court of competent jurisdiction determines that the CFO breached any

of the provisions of Sections 5 or 6, the Company will have the right to cease making any payments or providing any benefits otherwise due to
the CFO under the terms and conditions of this Agreement. 
 (c) Claims by the CFO. The CFO acknowledges and agrees
that any claim or cause of action by the CFO against the Company shall not constitute a defense to the enforcement of the restrictions and covenants set forth in this Agreement and shall not be used to prohibit injunctive relief.

 (a) By the CFO. The CFO shall not assign, transfer or delegate this Agreement or any right, duty, obligation, or interest under
this Agreement without the Company’s prior written consent; provided, however, that nothing shall preclude the CFO from designating beneficiaries to receive compensation or benefits, if any, payable under this Agreement upon his death.

 (b) By the Company. The Company shall not assign, transfer or delegate this Agreement or any right, duty, obligation
or intent under this Agreement without the CFO’s prior written consent; provided, however, that the Company may assign this Agreement and all of its rights and obligations hereunder to any person who or entity that shall acquire all or
substantially all of the assets and properties of the Company in a bona fide sale transaction.

Notice, or the actual date the CFO terminates employment with the Company as the result of a resignation as provided in whichever occurs earlier.

employment. 
 Section 11. Severability. If a court of competent jurisdiction makes a final determination that any term or
provision of this Agreement is invalid or unenforceable, and all rights to appeal the determination have been exhausted or the period of time during which any appeal of the determination may be perfected has been exhausted, the remaining terms and
provisions shall be unimpaired and the invalid or unenforceable term or provision shall be deemed replaced by a term or provision that is valid and enforceable and that most closely approximates the intention of the parties with respect to the
invalid or unenforceable term or provision, as evidenced by the remaining valid and enforceable terms and conditions of this Agreement. 
 Section 12. Amendment. This Agreement may not be modified, amended, or waived in any manner except by a written instrument signed by both parties to this Agreement.

be construed as a waiver of any other provision of this Agreement (whether or not similar), or a continuing waiver or a waiver of any subsequent breach by a party of a provision of this Agreement. Performance by any of the parties of any act not
required of it under the terms and conditions of this Agreement shall not constitute a waiver of the limitations on its obligations under this Agreement, and no performance shall estop that party from asserting those limitations as to any further or
future performance of its obligations.

enforced in accordance with the laws of the State of Illinois, without regard to principles of conflict of laws of such State.
