 RUBICON TECHNOLOGY, INC. 

 2001 EQUITY PLAN 
 STOCK OPTION AGREEMENT 
 1. Grant of Option. 
 (a) The Administrator of the Company hereby grants to the optionee (the “Optionee”) named in the Notice of Stock Option Grant (the “Notice”) to which this Stock Option Agreement (the “Option
Agreement”) is attached an option (the “Option”) to purchase the number of shares, as set forth in such Notice, at the exercise price per share set forth in the Notice (the “Exercise Price”), subject to the terms and
conditions of the Plan, which is incorporated herein by reference. Subject to provisions of the Plan stating otherwise, in the event of a conflict between the terms and conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail. 
 (b) This Option is not intended to qualify as an Incentive Stock Option under
Section 422 of the Code unless it is so designated in the Notice as an Incentive Stock Option. However, if this Option is designated to be an Incentive Stock Option, to the extent that it exceeds the limit set forth in Section 422(d) of
the Code, it shall be treated as a Non-qualified Stock Option. 
 2. Exercise of Option. 
 (a) Right to Exercise. Subject to Sections 2(c), 2(d), and 2(e) below, this Option is exercisable during its term in accordance with the
Vesting Schedule set out in the Notice and the applicable provisions of the Plan and this Option Agreement. 
 (b) Method of Exercise.
The Option is exercisable by delivery of an exercise notice, in the form attached as Exhibit A (the “Exercise Notice”), which shall state the election to exercise the Option, the number of Shares in respect of which the Option is
being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan. The Exercise Notice shall be completed by the Optionee, or personal
representative of the Optionee as provided in the Plan, and delivered to an officer of the Company. The Exercise Notice shall be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares. The Option shall be deemed to be
exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by such aggregate Exercise Price. 
 (c)
Compliance with Law. No Shares shall be issued pursuant to the exercise of this Option unless such issuance and exercise complies with Applicable Laws. Assuming such compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to such Exercised Shares. 
 (d) Merger, Reorganization or
Sale. In the event of any merger, consolidation, or similar reorganization of the Company with any other entity pursuant to which the holders of Shares surrender Shares (or the Shares are deemed converted) in exchange for other shares of capital
stock or securities of the Company or another entity or the sale of substantially all of the assets of the Company, if the Option is not assumed or an equivalent option or right is not substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation, then the Optionee shall fully vest in and have the right to exercise the Option as to all of the Optioned Stock, including Shares as to which it would not otherwise be vested or exercisable. If the Option
becomes fully 
  

					
	RUBICON TECHNOLOGY, INC.	  	-1-	  	STOCK OPTION AGREEMENT

 
vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Optionee in
writing or electronically that the Option shall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and the Option shall terminate upon the expiration of such period. For the purposes of this
Section 2(d), the determination of whether the Option has been assumed or substituted shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. 
 (e) Death or Disability. Upon the death or Disability of Optionee, all Shares subject to the Option shall immediately vest, and the Option shall
become immediately exercisable with respect to all Shares subject to the Option in accordance with this Option Agreement and the Plan. 
 (f)
Restrictions on Voting. Until the occurrence of an underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under the Securities Act, Optioned Stock will be voted by the
Chairman of the Board of the Company, pursuant to an irrevocable proxy in the form attached hereto as Exhibit B (the “Proxy”). As a condition precedent to the exercise of the Option, Optionee shall agree to be bound by the terms and
conditions of the Proxy and shall deliver an executed version of the Proxy with the executed Exercise Notice. The Proxy shall be binding upon the estate, heirs, successors and assigns of the Optionee. 
 3. Method of Payment. 
 Payment of the aggregate
Exercise Price shall be by any of the following, or a combination thereof, at the election of the Optionee: 
 (a) cash; or 
 (b) certified check; or 
 (c) such other
consideration as permitted by the Administrator in its sole discretion. 
 4. Non-Transferability of Option. 
 This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime
of Optionee only by the Optionee. The terms of the Plan and this Option Agreement shall be binding upon the executors, administrators, heirs, successors and assigns of the Optionee. 
 5. Term of Option. 
 This Option may be exercised only within the term set out in the Notice of Grant,
and may be exercised during such term only in accordance with the Plan and the terms of this Option Agreement. 
 6. Other Restrictions. 

(a) Stockholders’ Agreement. As a condition precedent to the exercise of the Option, Optionee shall agree to be bound by the terms and
conditions of that certain Amended and Restated Stockholder’s Agreement, dated as of June 28, 2005, by and between the Company and the Stockholders of the Company (as defined therein) (the “Stockholders’ Agreement”).
Optionee shall, upon exercise of the Option, deliver an executed version of the Adoption of Stockholders’ Agreement, attached hereto as Exhibit C, to the Company. Optionee agrees to be bound by the Stockholders’ Agreement as an
Other Stockholder (as defined therein). 
 (b) Repurchase Option. In addition to the restrictions within the Stockholder’s
Agreement, in the event that Optionee ceases to be a Service Provider, whether voluntarily or involuntarily, due to death, Disability or otherwise, the Company may purchase from Optionee or Optionee’s estate, heirs, beneficiaries,
representatives or successors in interest (the “Successors”), until the later of (i) one (1) year after the date the Optionee ceases to be a Service Provider of the Company, or (ii) one (1) year after the exercise by
the Optionee or the Successors of any vested portion of the Option, all, or any portion of, Optionee’s Optioned Stock, at a price equal to the fair market value of such Optioned Stock as of the purchase date as determined by the Company’s
Board in its sole and absolute discretion to the extent permitted by the Stockholders’ Agreement in accordance with Section 2.5 of the Stockholders’ Agreement. 
 7. Restrictions on Transfer. 
 (a) Securities Law Restrictions. Regardless of whether the
offering and sale of Shares under the Plan have been registered under the Securities Act or have been registered or qualified under the securities laws of any 

  

					
	RUBICON TECHNOLOGY, INC.	  	-2-	  	STOCK OPTION AGREEMENT

 
state, the Company at its discretion may impose restrictions upon the sale, pledge or other transfer of such Shares (including the placement of appropriate
legends on stock certificates or the imposition of stop-transfer instructions) if, in the judgment of the Company, such restrictions are necessary or desirable in order to achieve compliance with the Securities Act, the securities laws of any state
or any other law. 
 (b) Market Stand-Off. In connection with any underwritten public offering by the Company of its equity securities
pursuant to an effective registration statement filed under the Securities Act, including the Company’s initial public offering, the Optionee shall not directly or indirectly without the prior written consent of the Company or its underwriters
(i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of, lend or otherwise dispose of or transfer any Shares or any
securities convertible into or exchangeable or exercisable for such Common Stock, whether now owned or hereafter acquired by the Optionee or with respect to which the Optionee has or hereafter acquires the power of disposition or file any
registration statement under the Securities Act with respect to any of the foregoing or (ii) enter into any swap or any other agreement or any transaction that transfers, in whole or in part, directly or indirectly, the economic consequence of
ownership of such Common Stock or any securities convertible into or exchangeable or exercisable for such Common Stock, whether any such swap or transaction is to be settled by delivery of such Common Stock or other securities in cash or otherwise
or (iii) agree to engage in any of the foregoing transactions. Such restriction, or other substantially similar restriction requested by the underwriters (in either case, the “Market Stand-Off”) shall be in effect for such period of
time following the date of the final prospectus for the offering as may be requested by the Company or such underwriters. In the event of the declaration of a stock dividend, a spin-off, a stock split, an adjustment in conversion ratio, a
recapitalization or a similar transaction affecting the Company’s outstanding securities without receipt of consideration, any new, substituted or additional securities which are by reason of such transaction distributed with respect to any
Shares subject to the Market Stand-Off, or into which such Shares thereby become convertible, shall immediately be subject to the Market Stand-Off. In order to enforce the Market Stand-Off, the Company may impose stop-transfer instructions with
respect to the Shares acquired under this Option Agreement until the end of the applicable stand-off period. The Company’s underwriters shall be beneficiaries of the agreement set forth in this Section 7(b). This Section 7(b) shall
not apply to Shares registered in the public offering under the Securities Act, and the Optionee shall be subject to this Section 7(b) only if the directors and officers of the Company are subject to similar arrangements. The Optionee agrees to
evidence the Market Stand-Off by execution of a written lock-up letter addressed to such underwriters if and to the extent and in such form as may be requested by such underwriters. 
 (c) Investment Intent at Grant. The Optionee represents and agrees that the Shares to be acquired upon exercising this Option will be acquired for
investment, and not with a view to the sale or distribution thereof. 
 (d) Investment Intent at Exercise. In the event that the sale
of Shares under the Plan is not registered under the Securities Act but an exemption is available which requires an investment representation or other representation, the Optionee shall represent and agree at the time of exercise that the Shares
being acquired upon exercising this Option are being acquired for investment, and not with a view to the sale or distribution thereof, and shall make such other representations as are deemed necessary or appropriate by the Company and its counsel.

 (e) Securities Legend. All certificates evidencing Shares purchased under this Option Agreement in an unregistered transaction
shall bear the following legend (and such other restrictive legends as are required or deemed advisable under the provisions of any applicable law):

COMPANY, THAT THE PROPOSED DISPOSITION MAY BE EFFECTED IN COMPLIANCE WITH APPLICABLE SECURITIES LAWS WITHOUT REGISTRATION. ADDITIONAL RESTRICTIONS ON TRANSFER ARE SET FORTH HEREIN.

 (h) Removal of Legends. If, in the opinion of the Company and its counsel, any legend placed on a stock certificate representing Shares sold under this Option Agreement is no longer required, the holder of such certificate shall be
entitled to exchange such certificate for a certificate representing the same number of Shares but without such legend. 
 (i)
Administration. Any determination by the Company and its counsel in connection with any of the matters set forth in this Section 7 shall be conclusive and binding on the Optionee and all other persons.

interest except by means of a writing signed by the Company and Optionee. This Option Agreement is governed by the internal substantive laws, but not the choice of law rules, of the State of Illinois. 
 9. NO PROMISE OR GUARANTEE OF CONTINUED SERVICE. OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE OPTION PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED

TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL NOT INTERFERE

having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by an Optionee to
have Shares withheld for this purpose shall be made in such form and under such conditions as the Committee may deem necessary or advisable; 

  

	 	(k)	to authorize any person to execute on behalf of the Company any instrument required to effect the grant of an Award previously granted by the Committee;

	6.2	Designation As Either An Incentive Stock Option or As A Nonstatutory Stock Option; $100,000 Limitation. Each Option shall be designated in the Option Agreement as either an

the Optionee during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds One Hundred Thousand Dollars ($100,000), such Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6.2,

	6.3	Option Term. The term of each Option shall be ten (10) years from the date of grant or such shorter term as may be provided in the Option Agreement. In the case of an

Subsidiary, the term of the Incentive Stock Option shall be five (5) years from the date of grant or such shorter term as may be provided in the Option Agreement.

	 	(1)	granted to an Employee who, at the time the Incentive Stock Option is granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock
of the Company or any Parent or Subsidiary, the per Share exercise price shall be no less than one hundred ten percent (110%) of the Fair Market Value per Share on the Date of Grant. 

  

	 	(2)	granted to any Employee other than an Employee described in paragraph (1) immediately above, the per Share exercise price shall be no less than one hundred percent
(100%) of the Fair Market Value per Share on the Date of Grant. 

  

	 	(b)	In the case of a Nonstatutory Stock Option, the per Share exercise price shall be determined by the Committee; provided, however, that the per Share exercise price shall not be less
than one hundred percent (100%) of the Fair Market Value per Share on the Date of Grant. 

  

	6.5	Waiting Period and Exercise Dates. At the time an Option is granted, the Committee shall fix the period within which the Option may be exercised and shall determine any
conditions which must be satisfied before the Option may be exercised.

	 	(c)	other Shares which (1) in the case of Shares acquired upon exercise of an Option, have been owned by the Optionee for more than six (6) months on the date of surrender,

	 	(d)	consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan to the extent permitted by Applicable Laws;

	 	(g)	such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws. 

 In the case of an Incentive Stock Option, the Committee shall determine the acceptable form of consideration at the time of grant. 
  

	6.7	Procedure for Exercise; Rights as a Shareholder. Any Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under
such conditions as determined by the Committee and set forth in the Option Agreement. Unless the Committee provides otherwise, vesting of any Option granted hereunder shall be tolled during any unpaid leave of absence. An Option may not be exercised
for a fraction of a Share. 

  

	 	(a)	An Option shall be deemed exercised when the Company receives: (i) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled
to exercise the Option, (ii) the Irrevocable Proxy, duly executed, in the form attached hereto as Exhibit A if the Option is exercised prior to the Company’s Initial Public Offering, (iii) full payment for the Shares with respect to
which the Option is exercised, and (iv) any other written representations, covenants, and undertakings that the Company may prescribe in the Option Agreement. Full payment may consist of any consideration and method of payment authorized by the
Committee and permitted by the Option Agreement and the Plan. Shares issued upon exercise of an Option shall be issued in the name of the Optionee or, if requested by the Optionee, in the name of the Optionee and his or her spouse. Until the Shares
are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned
Stock, notwithstanding the exercise of the Option. The Company shall issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment will be made for a dividend or other right for which the record date is prior to the
date the Shares are issued, except as provided in Article 13 of the Plan. 

  

	 	(b)	Exercising an Option in any manner shall decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Shares as
to which the Option is exercised. 

  

	 	(c)	The Committee may suspend the right to exercise a Stock Option at any time when the Committee determines that allowing the exercise and issuance of Stock would violate any federal
or state securities or other laws. The Committee may provide that any time periods to exercise the Stock Option are extended during a period of suspension. 

  

					
	RUBICON TECHNOLOGY, INC.	  	-13-	  	2007 STOCK INCENTIVE PLAN

	6.8	Notification under Code Section 83(b). If the Optionee, in connection with the exercise of any Option, makes the election permitted under Code Section 83(b) to
include in such Optionee’s gross income in the year of transfer the amounts specified in Code Section 83(b), then such Optionee shall notify the Company of such election within ten (10) days of filing the notice of the election with
the Internal Revenue Service, in addition to any filing and notification required pursuant to regulations issued under Code Section 83(b). The Committee may, in connection with the grant of an Option or at any time thereafter prior to such an
election being made, prohibit an Optionee from making the election described above. 

  

	6.9	Buyout Provisions. The Committee may at any time offer to buy out for a payment in cash or Shares an Option previously granted based on such terms and conditions as the
Committee shall establish and communicate to the Optionee at the time that such offer is made. 

  

	6.10	Modifications Generally Prohibited. Once granted, no Modification shall be made in respect to any Option if such Modification would result in the Option constituting a
deferral of compensation or having an additional deferral feature within the meaning of applicable Treasury Regulations under Code Section 409A. 

  

	6.11	Non-Transferability of Options. An Option that is an Incentive Stock Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any
manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. Unless determined otherwise by the Committee, a Nonstatutory Stock Option may not be sold, pledged,
assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee. If the Committee grants a Nonstatutory Stock Option that is
transferable, the Option Agreement for such Nonstatutory Stock Option shall contain such additional terms and conditions governing the Option’s transferability as the Committee deems appropriate. 

  

	6.12	Termination of Service Provider For Cause. If a Service Provider is terminated for Cause, any unexercised Option shall terminate effective immediately upon such termination.

  

	6.13	Disability of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee’s Disability, the Optionee may exercise his or her Option within such
period of time as is specified in the Option Agreement to the extent the Option is vested and exercisable on the date of termination (but in no event later than the expiration of the term of such Option as set forth in the Option Agreement);
provided, however, that the time specified in the Option Agreement shall not be less than six (6) months. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for twelve (12) months following the
Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after termination, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 

  

	6.14	Death of Optionee. If an Optionee dies while a Service Provider, the Option may be exercised within such period of time as is specified in the Option Agreement (but
in no event later than the expiration of the term of such Option as set forth in the Notice of Grant), by the Optionee’s estate or by a person who acquires the right to exercise the Option by bequest or inheritance, but only to the extent that
the Option is vested and exercisable on the date of death; provided, however, that the time specified in the Option Agreement shall not be less than six (6) months. In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for six (6) months following the Optionee’s death. If, at the time of death, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall immediately revert to
the Plan. The Option may be exercised by the executor or administrator of the Optionee’s estate or, if none, by the person(s) entitled to exercise the Option under the Optionee’s will or the laws of descent or distribution. If the Option
is not so exercised within the time specified herein, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan.

	6.15	For Any Other Reason. If an Optionee ceases to be a Service Provider, other than for Cause or upon the Optionee’s death or Disability, the Optionee may exercise his or
her Option within such period of time as is specified in the Option Agreement to the extent that the Option is vested and exercisable on the date of termination (but in no event later than the expiration of the term of such Option as set forth in
the Option Agreement); provided, however, that the time specified in the Option Agreement shall not be less than thirty (30) days. In the absence of a specified time in the Option Agreement, the Option shall remain exercisable for three
(3) months following the Optionee’s termination. If, on the date of termination, the Optionee is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option shall revert to the Plan. If, after
termination, the Optionee does not exercise his or her Option within the time specified by the Committee, the Option shall terminate, and the Shares covered by such Option shall revert to the Plan. 

 ARTICLE 7 
 Stock Appreciation Rights

  

	7.1	Generally. Subject to the limitations of the Plan, the Committee may grant Stock Appreciation Rights to Service Providers. Stock Appreciation Rights may be granted in

	7.2	Stock Appreciation Rights Not Granted In Connection With Options. The following provisions apply to all Stock Appreciation Rights that are not granted in connection with
Options: 

  

	 	(a)	Described. A Stock Appreciation Right shall entitle the Awardee, upon exercise of all or any part of the Stock Appreciation Right, to receive in exchange from the Company an
amount equal to the excess of (x) the Fair Market Value on the date of exercise of the Shares covered by the surrendered Stock Appreciation Right over (y) the Fair Market Value of the Shares on the Date of Grant of the Stock Appreciation
Right. The Committee may not revise or amend a Stock Appreciation Right to reduce the Fair Market Value of the Stock Appreciation Right on the Date of Grant, except as provided in Article 13 of the Plan. 

  

	 	(b)	Term. The term of each Stock Appreciation Right shall be ten (10) years from the Date of Grant or such shorter term as may be provided in the Award Agreement. No Stock
Appreciation Right may be exercised after the expiration of its term.

exercised and shall determine any conditions which must be satisfied before the Stock Appreciation Right may be exercised. A Stock Appreciation Right may only be exercised at a time when the Fair Market Value of the Shares covered by the Stock
Appreciation Right exceeds the Fair Market Value of the Shares on the Date of Grant of the Stock Appreciation Right. 

  

	 	(d)	Exercise. Any Stock Appreciation Right granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such conditions as determined by
the Committee and set forth in the Award Agreement. Unless the Committee provides otherwise, vesting of any Stock Appreciation Right granted hereunder shall be tolled during any unpaid leave of absence. A Stock Appreciation Right may not be

	 	(e)	Effect of Exercise Upon Available Shares. Exercising a Stock Appreciation Right in any manner shall decrease the number of Shares thereafter available, both for purposes of
the Plan and for sale under the Stock Appreciation Right, by the number of Shares as to which the Stock Appreciation Right is exercised. 

  

	 	(f)	Notification under Code Section 83(b). If the Awardee, in connection with the exercise of any Stock Appreciation Right, makes the election permitted under Code
Section 83(b) to include in such Awardee’s gross income in the year of transfer the amounts specified in Code Section 83(b), then such Awardee shall notify the Company of such election within ten (10) days of filing the notice of
the election with the Internal Revenue Service, in addition to any filing and notification required pursuant to regulations issued under Code Section 83(b). The Committee may, in connection with the grant of a Stock Appreciation Right or at any
time thereafter prior to such an election being made, prohibit an Awardee from making the election described above.

transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Awardee, only by the Awardee. If the Committee grants a Stock Appreciation Right that is
transferable, the Award Agreement for such Stock Appreciation Right shall contain such additional terms and conditions governing the Stock Appreciation Right’s transferability as the Committee deems appropriate. 

  

	 	(i)	Termination of Service Provider For Cause. If a Service Provider is terminated for Cause, any unexercised Stock Appreciation Right shall terminate effective immediately upon
such termination. 

  

	 	(j)	Disability of Awardee. If an Awardee ceases to be a Service Provider as a result of the Awardee’s Disability, the Awardee may exercise his or her Stock Appreciation
Right within such period of time as is specified in the Award Agreement to the extent the Stock Appreciation Right is vested and exercisable on the date of termination (but in no event later than the expiration of the term of such Stock Appreciation
Right as set forth in the Award Agreement); provided, however, that the time specified in the Award Agreement shall not be less than six (6) months. In the absence of a specified time in the Award Agreement, the Stock Appreciation Right shall
remain exercisable for twelve (12) months following the Awardee’s termination. If, on the date of termination, the Awardee is not vested as to his or her entire Stock Appreciation Right, the Shares covered by the unvested portion of the
Stock Appreciation Right shall revert to the Plan. If, after termination, the Awardee does not exercise his or her Stock Appreciation Right within the time specified herein, the Stock Appreciation Right shall terminate, and the Shares covered by
such Stock Appreciation Right shall revert to the Plan.

the Stock Appreciation Right is vested and exercisable on the date of death; provided, however, that the time specified in the Award Agreement shall not be
less than six (6) months. In the absence of a specified time in the Award Agreement, the Stock Appreciation Right shall remain exercisable for six (6) months following the Awardee’s death. If, at the time of death, the Awardee is not
vested as to his or her entire Stock Appreciation Right, the Shares covered by the unvested portion of the Stock Appreciation Right shall immediately revert to the Plan. The Stock Appreciation Right may be exercised by the executor or administrator
of the Awardee’s estate or, if none, by the person(s) entitled to exercise the Stock Appreciation Right under the Awardee’s will or the laws of descent or distribution. If the Stock Appreciation Right is not so exercised within the time
specified herein, the Stock Appreciation Right shall terminate, and the Shares covered by such Stock Appreciation Right shall revert to the Plan. 

  

	 	(l)	For Any Other Reason. If an Awardee ceases to be a Service Provider, other than for Cause or upon the Awardee’s death or Disability, the Awardee may exercise his or her
Stock Appreciation Right within such period of time as is specified in the Award Agreement to the extent that the Stock Appreciation Right is vested and exercisable on the date of termination (but in no event later than the expiration of the term of
such Stock Appreciation Right as set forth in the Award Agreement); provided, however, that the time specified in the Award Agreement shall not be less than thirty (30) days. In the absence of a specified time in the Award Agreement, the Stock
Appreciation Right shall remain exercisable for three (3) months following the Awardee’s termination. If, on the date of termination, the Awardee is not vested as to his or her entire Stock Appreciation Right, the Shares covered by the

terminate, and the Shares covered by such Stock Appreciation Right shall revert to the Plan. 

  

	7.3	Stock Appreciation Rights Granted In Connection With Options. The following provisions apply to all Stock Appreciation Rights that are granted in connection with Options:

  

	 	(a)	A Stock Appreciation Right granted in connection with an Option must be granted on the same Date of Grant as the Option to which it relates. 

  

	 	(b)	A Stock Appreciation Right granted in connection with an Option shall entitle the Awardee, upon exercise of all or any part of the Stock Appreciation Right, to surrender to the
Company unexercised that portion of the underlying Option relating to the same number of Shares as is covered by the Stock Appreciation Right (or the portion of the Stock Appreciation Right so exercised) and to receive in exchange from the Company
an amount equal to the excess of (x) the Fair Market Value on the date of exercise of the Shares covered by the surrendered portion of the underlying Option over (y) the exercise price of the Shares covered by the surrendered portion of
the underlying Option. 

  

	 	(c)	Upon the exercise of a Stock Appreciation Right and surrender of the related portion of the underlying Option, the Option, to the extent surrendered, shall not thereafter be
exercisable. 

  

	 	(d)	Subject to any further conditions upon exercise imposed by the Committee, a Stock Appreciation Right shall be exercisable only to the extent that the related Option is exercisable
and a Stock Appreciation Right shall lapse or be forfeited no later than the date on which the related Option lapses or is forfeited. 

  

					
	RUBICON TECHNOLOGY, INC.	  	-17-	  	2007 STOCK INCENTIVE PLAN

	 	(e)	A Stock Appreciation Right shall terminate and shall no longer be exercisable upon the exercise of the related Option. 

  

	 	(f)	The Stock Appreciation Right is only transferable when the related Options are otherwise transferable. 

  

	 	(g)	A Stock Appreciation Right may only be exercised at a time when the Fair Market Value of the Shares covered by the Stock Appreciation Right exceeds the exercise price of the Shares
covered by the underlying Option. 

  

	7.4	Form of Payment. The manner in which the Company’s obligation arising upon the exercise of a Stock Appreciation Right shall be paid shall be determined by the Committee
and shall be set forth in the Award Agreement. The Award Agreement may provide for payment in (i) Shares, (ii) cash, (iii) a fixed combination of Shares or cash, or (iv) the Committee may reserve the right to determine the manner
of payment at the time the Stock Appreciation Right is exercised. Shares of Common Stock issued upon the exercise of a Stock Appreciation Right shall be valued at their Fair Market Value on the date of exercise. Any Shares issued upon exercise of a
Stock Appreciation Right shall be issued in the name of the Awardee or, if requested by the Awardee, in the name of the Awardee and his or her spouse. Until Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a
duly authorized transfer agent of the Company), in payment of a Stock Appreciation Right, no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Stock Appreciation Right, notwithstanding the
exercise of the Stock Appreciation Right. The Company shall issue (or cause to be issued) Shares that are to be issued in payment of a Stock Appreciation Right promptly after the Stock Appreciation Right is exercised. No adjustment will be made for
a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Article 13 of the Plan. 

  

	7.5	Procedure for Exercise; Rights As a Shareholder. A Stock Appreciation Right shall be deemed exercised when the Company receives a written or electronic notice of exercise (in
accordance with the Award Agreement) from the person entitled to exercise the Stock Appreciation Right. In addition, if the Stock Appreciation Right provides for the delivery of Shares in settlement of the Company’s obligation under the Stock
Appreciation Right, prior to the delivery of Shares, the Company must also receive from the person entitled to exercise the Stock Appreciation Right: (i) the Irrevocable Proxy, duly executed, in the form attached hereto as Exhibit A if the
Stock Appreciation Right is exercised prior to the Company’s Initial Public Offering and (ii) any other written representations, covenants, and undertakings that the Company may prescribe in the Award Agreement. 

 

	7.6	Modifications Generally Prohibited. Once granted, no Modification shall be made in respect to any Stock Appreciation Right if such Modification would result in the Stock
Appreciation Right constituting a deferral of compensation or having an additional deferral feature within the meaning of applicable Treasury Regulations under Code Section 409A.

Internal Revenue Service, in addition to any filing and notification required pursuant to regulations issued under Code Section 83(b). The Committee may, in connection with the grant of Restricted Stock or at any time thereafter prior to such

such Award (the “Restriction Period”), the Awardee shall not be permitted to sell, assign, transfer, pledge or otherwise encumber shares of Restricted Stock. The Committee may provide for the lapse of such restrictions in installments or
otherwise and may accelerate or waive such restrictions, in whole or in part, in each case based on period of service, performance of the Awardee or of the Company for which the Awardee is employed or such other factors or criteria as the Committee
may determine. 

  

	 8.8
	 Rights as a Shareholder. Except as otherwise provided in this Plan, the applicable Restricted Stock Agreement,
and the Irrevocable Proxy, the Awardee shall have, with respect to the Shares of Restricted Stock, all of the rights of a stockholder of the Company holding the class or series of stock that is the subject of the Restricted Stock, including, if
applicable, the right to vote the Shares and the right to receive any cash dividends. Absent a provision regarding the disposition of dividends in the applicable Restricted Stock Agreement, any dividend payable with respect to Restricted Stock shall
be paid to the Service Provider no later than the end of the calendar year in which the same dividends on Shares are paid to the shareholders of such Shares generally, or if later, the 15th day of the third month following the date on which the same dividends on Shares are paid to the Shares’ shareholders.

termination shall be forfeited effective immediately upon such termination.

right to receive a Share of Common Stock or the Fair Market Value in cash of a Share of Common Stock, in the future, at such time and contingent upon such terms as the Committee shall establish. 

  

	9.2	Administration. Restricted Stock Units may be granted either alone or in addition to other Awards granted under the Plan. The Committee shall determine the Service Providers
to whom, and the time(s) at which grants of Restricted Stock Units will be made, the number of Restricted Stock Units to be awarded to any Service Provider, the time(s) within which, and the conditions under which such Restricted Stock Unit may be

	9.3	Terms and Conditions. The Committee shall establish as to each grant of Restricted Stock Units the terms and conditions upon which such Restricted Units shall become vested.
The Committee may base the vesting of Restricted Stock Units upon (i) the continued employment or service of the Awardee, (ii) the achievement of performance objectives, or (iii) a combination thereof. The Committee may provide for
the vesting of Restricted Stock Units in installments or otherwise and may accelerate or waive such restrictions, in whole or in part, in each case based on period of service, performance of the Awardee or of the Company for which the Awardee is
employed or such other factors or criteria as the Committee may determine. 

  

	9.4	Dividend Equivalents. If (and only if) expressly authorized in the applicable Award Agreement, in the event that the Company pays any cash or other dividend or makes any
other distribution in respect of the Common Stock, a Service Provider will be credited with an additional number of Restricted Stock Units (including fractions thereof) determined by dividing (i) the amount of cash, or the value (as determined
by the Committee) of any securities or other property, paid or distributed in respect of a Share by (ii) the Fair Market Value of a Share for the date of such payment or distribution, and multiplying the result of such division by
(iii) the number of Restricted Stock Units that were credited to a Service Provider immediately prior to the date of the dividend or other distribution. Credits shall be made effective as of the date of the dividend or other distribution in
respect of the Common Stock to the bookkeeping account to which the Service Provider’s Restricted Stock Units are credited. Dividends credited to a Service Provider shall be subject to the same restrictions and shall be distributed at the same
time and in the same manner as the Restricted Stock Units to which they relate.

shareholder of the Company until the Shares are actually issued to the Service Provider pursuant to the terms of the applicable Award Agreement. The Shares may be issued without consideration. 

  

	9.7	Termination for Cause. If a Service Provider is terminated for Cause, any Restricted Stock Units previously granted to the Service Provider that have not been settled by the
delivery of cash or Shares shall be forfeited effective immediately upon such termination. 

  

	9.8	Termination Other Than for Cause. Except as otherwise provided in the applicable Award Agreement or as determined by the Committee, if a Service Provider ceases to be a
Service Provider other than for Cause, any Restricted Stock Units previously granted to the Service Provider that remain unvested as of the date of cessation shall be forfeited immediately upon such cessation. 

  

	9.9	Form of Payment. The manner in which the Company shall settle its obligation (if any) arising out of the grant of a grant of Restricted Stock Units shall be determined by the
Committee and shall be set forth in the Award Agreement. The Award Agreement may provide for payment in (i) Shares, (ii) cash, (iii) a fixed combination of Shares or cash, or (iv) the Committee may reserve the right to determine
the manner of payment at the time that the Restricted Stock Units are settled.

amount of compensation paid to the Awardee, and (ii) as provided in the Award Agreement for any other purpose. 

  

	 	(b)	In addition, if the Award Agreement for a grant of Restricted Stock Units provides for the delivery of Shares in settlement of the Company’s obligation under the Award, prior
to the delivery of any Shares, the Company must also receive from the Awardee (i) the Irrevocable Proxy, duly executed, in the form attached hereto as Exhibit A, if the Shares are to be delivered to the Awardee prior to the Company’s
Initial Public Offering, and (ii) any other written representations, covenants, and undertakings that the Company may prescribe in the Award Agreement. 

  

	 	(c)	Any Shares issued upon settlement of Restricted Stock Units shall be issued in the name of the Awardee or, if requested by the Awardee, in the name of the Awardee and his or her
spouse. Until Shares are actually issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), in settlement of Restricted Stock Units, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Award. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Article 13 of the Plan.

Until Shares are actually issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), in settlement of a Performance Award grant, no right to vote or receive dividends or any
other rights as a shareholder shall exist with respect to the Award. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Article 13 of the Plan.

 ARTICLE 11 
 Bonus Shares 
  

	11.1	Generally. Subject to the limitations of the Plan, the Committee may grant Bonus Shares to any Service Provider, in such amount and upon such terms, at any time and from time
to time as the Committee in its sole discretion shall determine. 

  

	11.2	Awards and Certificates. Prior to the delivery of any Shares to the Awardee in payment of a grant of Bonus Shares, the Company must receive from the Awardee (i) the
Irrevocable Proxy, duly executed, in the form attached hereto as Exhibit A, if the Shares are to be delivered to the Awardee prior to the Company’s Initial Public Offering, and (ii) any other written representations, covenants, and
undertakings that the Company may prescribe in the Award Agreement. Any Shares issued with respect to a grant of Bonus Shares shall be issued in the name of the Awardee or, if requested by the Awardee, in the name of the Awardee and his or her
spouse. Until Shares are actually issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall
exist with respect to the Award. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Article 13 of the Plan. 

  

	11.3	Non-Transferability. Until actually delivered to the Awardee, Bonus Shares may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner.

 ARTICLE 12 
 Designation of Awards as Performance-Based Compensation 
 The Committee may designate an Award of Restricted Stock, Restricted Stock Units, or
Performance Awards as intended to qualify as “performance based compensation” within the meaning of Code Section 162(m). 
  

	12.1	Any Award of Restricted Stock, Restricted Stock Units, or any Performance Award that is intended to qualify as performance-based compensation shall be, to the extent required by
Code Section 162(m), either (i) conditioned upon the attainment of one or more Performance Factors, or (ii) granted based upon the achievement of one or more Performance Factors. 

  

	12.2	Any Award of Restricted Stock, Restricted Stock Units, or any Performance Award that is intended to qualify as performance-based compensation shall also be subject to the following:

  

	 	(a)	No later than ninety (90) days following the commencement of each performance period (or such other time as may be required or permitted by Code Section 162(m)), the
Committee 

  

					
	RUBICON TECHNOLOGY, INC.	  	-23-	  	2007 STOCK INCENTIVE PLAN

	 	 
shall, in writing, (1) grant a target number of Shares or units, (2) select the performance goal or goals applicable to the performance period and
(3) specify the relationship between performance goals and the number of Shares or units that may be earned by an Awardee for such Performance Period. 

  

	 	(b)	Following the completion of each Performance Period, the Committee shall certify in writing whether the applicable performance objectives have been achieved and the number of units
or Shares, if any, earned by an Awardee for such Performance Period. 

  

	 	(c)	In determining the number of units or Shares earned by an Awardee for a given Performance Period, subject to any applicable Award Agreement, the Committee shall have the right to
reduce (but not increase) the amount earned at a given level of performance to take into account additional factors that the Committee may deem relevant to the assessment of individual or corporate performance for the Performance Period.

 ARTICLE 13 
 Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale 
  

	13.1	Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of Shares covered by each outstanding Award, and the number of Shares
which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been returned to the Plan as well as the price per Share covered by each outstanding Option and the base amount per Share of each
Stock Appreciation Right, shall be proportionately adjusted for any increase or decrease in the number of issued Shares resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Share, or any other
increase or decrease in the number of issued Shares effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without
receipt of consideration”; provided, however, that with respect to Incentive Stock Options, no such adjustment shall be authorized to the extent that such adjustment would cause the Plan to violate Code Section 422(b)(1); provided further,
that with respect to Options and Stock Appreciation Rights, no such adjustment shall be authorized to the extent such adjustment would cause the Options and Stock Appreciation Rights to become “deferred compensation” subject to Code
Section 409A. Such adjustment shall be made by the Committee, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to an Award. 

 ARTICLE 14 
 Cancellation and Rescission
of Awards 
  

	14.1	Cancellation of Awards. Unless the Award Agreement specifies otherwise, the Committee may cancel, rescind, suspend, withhold, or otherwise limit or restrict any unexercised
(in the case of Options or Stock Appreciation Rights), unvested, or unpaid Award at any time if the Awardee is not in compliance with all applicable provisions of the Award Agreement and the Plan, or if the Awardee has engaged in any Adverse
Conduct. 

  

	14.2	Certification of Compliance May Be Required. Upon exercise, payment or delivery pursuant to an Award, the Committee may require the Awardee to certify, in a manner acceptable
to the Company, that the Awardee is in compliance with the terms and conditions of the Plan. 

  

					
	RUBICON TECHNOLOGY, INC.	  	-24-	  	2007 STOCK INCENTIVE PLAN

	14.3	Rescission of Awards. Unless the Award Agreement specifies otherwise, for a period of two (2) years following the exercise, payment or delivery of an Award (the
“Rescission Period”), the Committee may rescind any such exercise, payment, or delivery of the Award upon its determination that the Awardee has engaged in Adverse Conduct prior to the delivery of the Award or during the Rescission Period.
In the event of any such rescission, the Awardee shall pay to the Company the amount of any gain realized or payment received as a result of the rescinded exercise, payment or delivery, in such manner and on such terms and conditions as may be
required. 

 ARTICLE 15 
 Change in Control Provisions 
  

	15.1	In the event of a merger or Change in Control, each outstanding Award will be treated as the Committee determines, including, without limitation, that each Award be assumed or an
equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Committee will not be required to treat all Awards similarly in the transaction. 

  

	15.2	In the event that the successor corporation does not assume or substitute for the Award, the Awardee will fully vest in and have the right to exercise all of his or her outstanding
Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with
performance-based vesting, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is
not assumed or substituted in the event of a Change in Control, the Committee will notify the Awardee in writing or electronically that the Option or Stock Appreciation Right will be fully vested and exercisable for a period of time determined by
the Committee in its sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 

  

	15.3	For the purposes of this Article 15, an Award will be considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share
subject to the Award immediately prior to the Change in Control, the consideration (whether stock, cash, or other securities or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the
transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control is not
solely common stock of the successor corporation or its Parent, the Committee may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of an Option or Stock Appreciation Right or upon the
payout of a Restricted Stock Unit, or Performance Award, for each Share subject to such Award (or in the case of an Award settled in cash, the number of implied shares determined by dividing the value of the Award by the per share consideration
received by holders of Common Stock in the Change in Control), to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the Change in
Control. 

  

	15.4	Notwithstanding anything in this Article 15 to the contrary, an Award that vests, is earned or paid-out upon the satisfaction of one or more performance goals will not be considered
assumed if the Company or its successor modifies any of such performance goals without the Awardee’s consent; provided, however, a modification to such performance goals only to reflect the successor corporation’s post-Change in Control
corporate structure will not be deemed to invalidate an otherwise valid Award assumption.

 ARTICLE 16 
 Amendment and Termination of the Plan 
  

	16.1	Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan. 

  

	16.2	Shareholder Approval. The Company shall obtain shareholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

  

	16.3	Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Awardee, unless
mutually agreed otherwise between the Awardee and the Committee, which agreement must be in writing and signed by the Awardee and the Company. Termination of the Plan shall not affect the Committee’s ability to exercise the powers granted to it
hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

 ARTICLE 17 

Conditions Upon Issuance of Shares 
  

	17.1	Legal Compliance. Shares shall not be issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares shall comply
with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance. Under no circumstances shall the Company be obligated to effect or maintain any registration under the Securities Act or
other similar Applicable Laws. 

  

	17.2	Investment Representations. As a condition to the exercise of an Award, the Company may require the person exercising such Award to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required. 

  

	17.3	Restrictions on Share Transferability. 

  

	 	(a)	Generally. The Committee may include in the Award Agreement such restrictions on any Shares acquired pursuant to the exercise or vesting of an Award as it may deem advisable,
including restrictions under applicable federal securities laws. 

  

	 	(b)	Market Standoff. In the event of an underwritten public offering by the Company of its equity securities pursuant to an effective resignation statement filed under the
Securities Act, including the Company’s Initial Public Offering, no person may sell, make any short sale of, loan, hypothecate, pledge, grant any option for the purchase of, or otherwise dispose of or transfer for value or otherwise agree to
engage in any of the foregoing transactions with respect to any Shares issued pursuant to an Award granted under the Plan without the prior written consent of the Company or its underwriters. Such limitations shall be in effect for such period of
time as may be requested by the Company or such underwriters; provided, however, that in no event shall such period exceed two hundred fourteen (214) days following the effective date of the registration statement. The limitations of this
Section 17.3(b) shall in all events terminate two years after the effective date of the Company’s Initial Public Offering. 

  

					
	RUBICON TECHNOLOGY, INC.	  	-26-	  	2007 STOCK INCENTIVE PLAN

	 	(1)	In the event of any stock split, stock dividend, recapitalization, combination of Shares, exchange of Shares or other change affecting the Company’s outstanding Common Stock
effected as a class without the Company’s receipt of consideration, any new, substituted or additional securities distributed with respect to the purchased Shares shall be immediately subject to the provisions of this Section 17.3(b), to
the same extent the purchased Shares are at such time covered by such provisions. 

  

	 	(2)	In order to enforce the limitations of this Section 17.3(b), the Company may impose stop-transfer instructions with respect to the purchased shares until the end of the
applicable stand off period. 

 ARTICLE 18 
 Additional Provisions 
  

	18.1	Term of Plan. Subject to Section 18.6 of the Plan, the Plan shall become effective upon its adoption by the Board. It shall continue in effect for a term of ten
(10) years unless terminated earlier under Article 16 of the Plan. 

  

	18.2	Unfunded Status of Plan. It is intended that the Plan shall constitute an “unfunded” plan for incentive and deferred compensation. The Committee may authorize the
creation of trusts or other arrangements to meet the obligations created under the Plan to deliver stock or make payments; provided, however, that the existence of such trusts or other arrangements is consistent with the “unfunded” status
of the Plan. 

  

	18.3	No Right to Continue As A Service Provider. Neither the Plan nor any Award shall confer upon an Awardee any right with respect to continuing the Awardee’s relationship
as a Service Provider with the Company, nor shall they interfere in any way with the Awardee’s right or the Company’s right to terminate such relationship at any time, with or without Cause. 

  

	18.4	Inability to Obtain Authority. The inability or failure of the Company to obtain authority from any regulatory body having jurisdiction (including, without limitation,
effectiveness of a registration statement under the Securities Act), which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in
respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained. 

  

	18.5	Reservation of Shares. The Company, during the term of this Plan, will at all times reserve and keep available such number of Shares as shall be sufficient to
satisfy the requirements of the Plan. 

  

	18.6	Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company within twelve (12) months after the date the Plan is adopted. Such
shareholder approval shall be obtained in the manner and to the degree required under Applicable Laws. If such shareholder approval is not obtained, all Awards granted under the Plan shall be cancelled. 

  

	18.7	No Right to Participation. No Employee, Director or Consultant shall have the right to be selected to receive an Award, or, having been so selected, to be selected to receive
a future Award. 

  

	18.8	Successors. All obligations of the Company under the Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of
such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise of all or substantially all of the business or assets of the Company. 

  

					
	RUBICON TECHNOLOGY, INC.	  	-27-	  	2007 STOCK INCENTIVE PLAN

	18.9   	Severability. If any part of the Plan is declared by any court or governmental authority to be unlawful or invalid, such unlawfulness or invalidity shall not invalidate any
other part of the Plan. Any Section or part of a Section so declared to be unlawful or invalid shall, if possible, be construed in a manner which will give effect to the terms of such Section or part of a Section to the fullest extent possible while
remaining lawful and valid. 

  

	18.10 	Designation of Beneficiary. The Committee may establish procedures allowing an Awardee to designate a beneficiary or beneficiaries to exercise any Award or receive any
payment under any Award payable on or after the Awardee’s death. 

  

	18.11 	Governing Law. The Plan shall be construed in accordance with and governed by the laws of the State of Illinois. 

  

	18.12 	Code Section 409A. To the extend that any Award shall constitute “deferred compensation” subject to Code Section 409A, such Award shall be administered in
accordance with the requirements of Code section 409A(a)(2)(A)(i), which prohibits the distribution of compensation subject to Code section 409A to a “specified employee” of a publicly traded company any earlier than six months after the
date of separation of service in the case of a distribution by reason of a separation of service.

 IRREVOCABLE PROXY 
 The undersigned
hereby revokes any previous proxies and irrevocably appoints the Chairman of the Board of Directors of Rubicon Technology, Inc. (the “Company”), and his successor or successors (the “Proxyholder”), pursuant to the Rubicon

hereafter acquired by the undersigned (collectively, the “Proxy Shares”), to execute written consents to corporate action, and to represent and otherwise act for the undersigned on any and all matters with the same force and effect as if
the undersigned were personally present at such meeting or were executing such consent.
