EXECUTIVE EMPLOYMENT AGREEMENT

Exhibit 10.2

THIS Executive Employment Agreement (“Agreement”) is made and entered into as of February 18, 2015 (the “Effective Date”), by and between Rubicon Technology, Inc., a Delaware corporation (the “Company”), and Xxxxxx X. Xxxxxx, a resident of the State of Illinois (the “Executive”).

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 Executive 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).

As a result of Executive’s previous employment as the Company’s Vice President – Finance, among other positions, and her current employment as the Company’s Chief Financial Officer (“CFO”) and Secretary, the Executive is well 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 Executive.

Capitalized terms used herein, but not otherwise defined, shall have the meanings ascribed to such terms in the Company’s 2007 Stock Incentive Plan, as amended (the “Plan”).

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 Executive shall serve as the CFO and Secretary of the Company, and shall report to the President and Chief Executive Officer of the Company (the “CEO”).

lawful directions and instructions given to her by the CEO and the Board of Directors (the “Board”); and (iv) use her best efforts to promote and serve the interests of the Company. The Executive shall comply in all material respects with all applicable laws, rules and regulations relating to the performance of the Executive’s duties and responsibilities hereunder.

(b) Exclusive Employment. Throughout the Employment Term, the Executive shall not render her services, directly or indirectly, to any person or entity other than the Company without the prior consent of the Board, which may be withheld or granted by the Board in its sole discretion. The Executive shall not engage in any activity which would materially interfere with the faithful and timely performance of her duties under this Agreement; provided, however, the Executive 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 Executive’s duties under this Agreement.

Section 2. Employment Term. The Executive’s employment as the Chief Financial Officer and Secretary commenced on December 9, 2014 and shall continue thereafter unless and until her employment is terminated pursuant to the terms of this Agreement. As used herein, “Employment Term” shall mean the actual period of time during which the Executive 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 Executive as full compensation for all services rendered by the Executive to the Company:

(a) Annual Salary. The Executive’s annual salary shall be Two Hundred Thousand Dollars ($200,000.00) (the “Annual Salary”), which shall be retroactive to January 1, 2015. 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 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 Executive’s prior written consent.

(b) Bonuses.

(i) In 2015, the Executive shall be eligible to receive a bonus of Sixty Thousand Dollars ($60,000.00) based upon the achievement of certain objectives and criteria mutually agreed upon by the Board and the Executive (the “Cash Bonus”).

The Cash Bonus, if achieved by Executive, will be paid no later than March 31, 2016, and shall be subject to applicable taxes, payroll deductions, and withholdings required by law. For years after 2015, the Board shall review the Executive’s eligibility for similar bonuses based upon the achievement of certain objectives and criteria mutually agreed upon by the Board and the Executive.

(i) Nonstatutory Stock Options. On December 1, 2015, the Company shall grant Executive Nonstatutory Stock Options under the Plan. The number of Options so granted shall reflect the number of whole Options nearest the target value of One Hundred Thousand Dollars ($100,000.00), determined using the Fair Market Value per Share as determined under the Plan as of the date of grant. The grant of such Nonstatutory Stock Options shall be evidenced by an Option Agreement which shall set forth the 10-year term of the Option, the exercise price, the applicable four year ratable vesting period (with immediate, accelerated full vesting upon a Change in Control), a 12-month period of exercise of the Options following the death of the Executive and all other conditions for the vesting or exercise of such Nonstatutory Stock Options.

The number of Restricted Stock Units so granted shall reflect the number of whole Shares nearest the target value of Fifty Thousand Dollars ($50,000.00), determined using the Fair Market Value per Share as determined under the Plan as of the date of grant. The grant of such Restricted Stock Units shall be evidenced by an Award Agreement which shall set forth the vesting conditions for the award, including, but not limited to, the applicable performance period, the performance metrics and any continued service required for the vesting of the Award. The Compensation Committee of the Board shall approve such performance metrics no later than March 31, 2015. The Award shall become fully vested upon a Change in Control.

(d) Employee Benefit Plans. The Executive 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.

The Executive shall be entitled to accrue twenty (20) vacation days per calendar year, which vacation days shall accrue proportionately throughout the year based on completed months of service. Any unused vacation days shall not be carried forward from one calendar year to the next. For purposes of this Agreement, the term “Termination Vacation Pay” shall mean, at the time of a termination of the Executive’s employment hereunder, the payment due to the Executive at the rate of the Annual Salary in effect at that time, on a daily basis, multiplied by the number of earned and unused vacation days for the then-current calendar year for the period between January 1 of such year and the Termination Date.

-3-

(f) Other Expenses. The Company shall reimburse the Executive for all reasonable and ordinary out-of-pocket business expenses incurred by the Executive in the scope of her employment hereunder. The Executive 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 Executive’s employment with the Company shall be subject to termination as follows:

(a) Termination for Cause. The Company may immediately terminate the Executive for Cause (as defined below) by giving written notice to the Executive. In the event of a termination for Cause, the Executive shall be entitled to payment of (i) that portion of any of Executive’s Annual Salary that the Executive earned through and including the Termination Date, at the rate of the Annual Salary in effect at that time, (ii) any Termination Vacation Pay, and (iii) any bonus earned 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 Executive prior to the Termination Date. Except as provided herein or required by applicable law, the Executive shall not be entitled to any other compensation or benefits. Termination for “Cause” shall mean termination by the Board of the Executive’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 Executive, that the Executive:

(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 Executive’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 Executive with written notice of Executive’s failure to substantially perform Executive’s material duties.

(b) Termination Without Cause. The Company may, in its sole discretion, terminate the Executive without Cause, by providing written notice to the Executive (the “Termination Notice”) at least thirty (30) calendar days prior to the Termination Date. In the event of a termination without Cause, the Executive shall be entitled to: (i) payment of that portion of any Executive’s Annual Salary that the Executive earned through and

-4-

including the Termination Date, at the rate of the Annual Salary in effect at that time; (ii) any Termination Vacation Pay; (iii) any bonus earned prior to the Termination Date that remains unpaid; (iv) payment of Executive’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 (6) month period thereafter; (v) immediate vesting of any Options granted pursuant to Section 3(c)(i) and immediate vesting of any Restricted Stock Units granted pursuant to Section 3(c)(ii); and (vi) immediate vesting of any other Options granted by the Company to the Executive; provided, however, that the Executive 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(d) throughout the period commencing on the Termination Date and continuing for a six (6) month period thereafter. Except as provided herein or required by applicable law, the Executive shall not be entitled to any other compensation or benefits. With respect to Section 4(b)(iv) 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.

(c) Resignation. The Executive may resign from her 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 Executive shall be entitled to payment of that portion of the Executive’s Annual Salary that the Executive earned through and including the Resignation Date, at the rate of the Annual Salary in effect at that time, any Termination Vacation Pay and any bonus earned 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 Executive shall not be entitled to any other compensation or benefits.

(d) Resignation for Good Reason. Notwithstanding Section 4(c), the Executive may terminate her 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” (as defined below) 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 Executive shall be entitled to: (i) payment of that portion of the Executive’s Annual Salary that the Executive earned through and including the Resignation Date, at the rate of the Annual Salary in effect at that time; (ii) any Termination Vacation Pay; (iii) any bonus earned prior to the Resignation Date that remains unpaid; (iv) payment of Executive’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 (6) month period thereafter; (v) immediate vesting of any Options granted pursuant to Section 3(c)(i) and immediate vesting of any Restricted Stock Units granted pursuant to Section 3(c)(ii); and (vi) immediate vesting of any other Options granted by the Company to the Executive; provided, however, that the Executive 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

-5-

obligated to continue any health and welfare benefits provided to the Executive under Section 3(d) throughout the period commencing on the Termination Date and continuing for a six (6) month period thereafter. Except as provided herein or required by applicable law, the Executive shall not be entitled to any other compensation or benefits. With respect to Section 4(d)(iv) 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 the resignation of the Executive’s employment by the Company by the Executive, because of (A) any reduction in the Executive’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 Executive, 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.

(e) Termination Subsequent To A Change In Control. Notwithstanding anything to the contrary herein, in the event that the Company, at any time within two (2) years after a Change in Control, terminates the Executive without Cause or the Executive resigns with Good Reason, the Executive shall be entitled to the payments and benefits set forth in Section 4(b) or 4(d), as the case may be, except that, in lieu of the payment pursuant to Section 4(b)(iv) and 4(d)(iv), the Company shall pay to the Executive a lump sum payment within thirty (30) days of the Termination Date or Resignation Date, as applicable. The lump sum payment shall be equal to fifty (50) percent of the Executive’s Annual Salary at the time of the Termination Date or Resignation Date, as the case may be, less all applicable taxes, payroll deductions and withholdings required by law. In addition, any unvested options under any then-existing Option Agreement shall immediately be fully vested and exercisable by the Executive.

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 Executive, 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 Executive shall be reduced to the maximum amount which may be paid without such payments in the aggregate constituting “excess parachute payments,” provided that such amount shall not be reduced below the payment as set forth in Section 4(b)(iv) or 4(d)(iv) as referenced above.

(f) Death. If the Executive dies, her employment with the Company and this Agreement shall automatically terminate on the date of her death. The Executive’s estate or personal representative shall be entitled to receive that portion of the Annual Salary that the Executive earned through and including the date of the Executive’s death, at the rate of the Annual Salary in effect at that time, any Termination Vacation Pay and any bonus earned prior to the date of the Executive’s death that remains unpaid. Except as provided herein or required by applicable law, neither the Executive’s estate nor her personal representative shall be entitled to any other compensation or benefits.

-6-

(g) Disability. The Executive shall be deemed “Permanently Disabled” when she has suffered any medically determinable physical or mental illness, injury or infirmity that prevents the Executive from performing her 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 Executive is disabled and that determination shall be binding and conclusive on the Executive (and any guardians or representatives for her). If the Executive becomes Permanently Disabled, the Company may terminate the Executive’s employment with the Company as a result of the Permanent Disability by providing written notice to the Executive thirty (30) calendar days prior to the Termination Date, or the Executive may resign from her employment with the Company by providing written notice to the Company thirty (30) calendar days prior to the Resignation Date. If the Executive resigns from employment with the Company as a result of a Permanent Disability or the Company terminates the Executive’s employment as a result of a Permanent Disability, the Executive shall be entitled to receive that portion of the Annual Salary, at the rate in effect when she became Permanently Disabled, that she earned through and including the Termination Date or Resignation Date, as applicable, less any amounts the Executive is entitled to receive under any disability insurance policy maintained by the Company, any Termination Vacation Pay and any bonus earned prior to the Termination Date or Resignation Date, as applicable, that remains unpaid. Except as provided herein or required by applicable law, the Executive shall not be entitled to any other compensation or benefits.

(h) Savings Clause. This paragraph 4(h) shall apply for so long as the Executive is a “specified employee” for purposes of Section 409A of the Code. The determination of whether the Executive is a “specified employee” shall be made in accordance with the policy of the Company or, if none, under the default rules in Section 1.409A-1(i) of the Treasury Regulations. Any amount otherwise payable to the Executive on account of the Executive’s separation from service as defined in Section 1.409A-1(h) of the Treasury Regulations that exceeds the limit provided in Section 1.409A-1(b)(9)(iii) of the Treasury Regulations shall not be paid before the date which is six (6) months and a day after the date of the Executive’s separation from service (or, if earlier, the date of the Executive’s death). Upon the expiration of the six-month deferral period referred to in the preceding sentence or the Executive’s death, all payments deferred pursuant to the preceding sentence shall be paid to the Executive (or the Executive’s estate in the event of the Executives death) in a lump sum.

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 Executive or the Company, which is in any way related to the past

-7-

or present Company’s Business and is either designated as confidential or not generally 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 Executive in connection with her employment by the Company, whether before, on or after the Effective Date.

(b) Non-Disclosure and Non-Use of Confidential Information. The Executive acknowledges that the Confidential Information of the Company is a valuable, unique asset of the Company and the Executive’s unauthorized use or disclosure thereof could cause irreparable harm to the Company for which no remedy at law could be adequate. Accordingly, the Executive agrees that she 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 Executive’s duties as an employee of the Company, she shall not, directly or indirectly, disclose or use or authorize any third party to disclose or use any Confidential Information. The Executive 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 Executive 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 Executive and whether or not disclosed to or entrusted to the custody of the Executive. Upon the termination or resignation of her employment by the Company, or at any other time at the request of the Company, the Executive 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 Executive 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

-8-

available to the public in a limited form and under limited circumstances does not change the confidential and proprietary nature of such information, and does not release the Executive from her duties with respect to such Confidential Information as set forth in this Agreement.

(e) Survival. The Executive’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 Executive’s employment by the Company, regardless of the reason therefor.

Section 7. Assignment of Inventions. Any and all inventions, improvements, discoveries, designs, works of authorship, concepts or ideas, or expressions thereof, whether or not subject to patents, copyrights, trademarks or service xxxx protections, and whether or not reduced to practice, that are conceived or developed by the Executive while employed with the Company and which relate to or result from the actual or anticipated business, work, research or investigation of the Company (collectively, “Inventions”), shall be the sole and exclusive property of the Company. The Executive shall do all things reasonably requested by the Company to assign to and vest in the Company the entire right, title and interest to any such Inventions and to obtain full protection therefor. Notwithstanding the foregoing, the provisions of this Agreement do not apply to an Invention for which no equipment, supplies, facility, or Confidential Information of the Company was used and which was developed entirely on the Executive’s own time, unless (a) the Invention relates (i) to Company’s Business, or (ii) to the Company’s actual or demonstrably anticipated research or development, or (b) the Invention results from any work performed by the Executive for the Company.

(a) Reasonableness. The Executive has carefully considered the nature, extent and duration of the restrictions and obligations contained in this Agreement, including, without limitation, the geographical coverage contained in Section 6 and the time periods contained in Section 5 and Section 6, and acknowledges and agrees that such restrictions are 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 Executive recognizes that any breach of this Agreement shall cause irreparable injury to the Company, inadequately compensable in monetary damages. Accordingly, in addition to any other legal or equitable remedies that may be available to the Company, the Executive agrees that the Company shall be able to seek and obtain injunctive relief in the form of a temporary restraining order, preliminary injunction, or permanent injunction, in each case without notice or bond, against Executive 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 Executive 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

-11-

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 Executive 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 Executive under the terms and conditions of this Agreement.

(c) Claims by the Executive. The Executive acknowledges and agrees that any claim or cause of action by the Executive 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.

Section 9. Nonassignability, Binding Agreement.

(a) By the Executive. The Executive 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 Executive from designating beneficiaries to receive compensation or benefits, if any, payable under this Agreement upon her 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 Executive’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.

(c) Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties, any successors or assigns of the Company and the Executive’s heirs and the personal representative(s) or executor(s) of the Executive’s estate.

Section 10. Definitions. The following capitalized terms shall have, throughout this Agreement, the following meanings:

(a) “Resignation Date” shall mean the date specified in the Resignation Notice, or the actual date the Executive terminates employment with the Company as the result of a resignation as provided in whichever occurs earlier.

(b) “Termination Date” shall mean the actual date the Executive ceases to be employed with the Company as a result of action taken by the Company, and not as a result of Executive’s resignation from employment.

Section 11. Judicial Modification and Severability. Executive agrees that if a court of competent jurisdiction should determine that any phrase or provision in this Agreement is invalid or unenforceable as written for any reason, the court shall modify and enforce any such phrase or provision to the maximum extent reasonably necessary to protect the Company’s legitimate business interests, so long as the modification does not render the phrase or provision

-12-

more restrictive with regard to Executive than originally drafted. Executive further agrees that if such modification of a phrase or provision that is invalid or unenforceable as written is legally impossible, the Court shall sever any such phrase or provision from this Agreement, and that the enforceability of all other provisions of this Agreement shall not be affected, but shall otherwise remain in full force and effect.
