 Exhibit 10.1 

FORM OF INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (“Agreement”) is made as of this
             day of             , 20     by and between Rubicon Technology, Inc., a Delaware corporation (the
“Company”), and the undersigned officer of the Company (“Indemnitee”). 
 WHEREAS, the Company and Indemnitee recognize
the increasing difficulty in obtaining directors’ and officers’ liability insurance, the significant increases in the cost of such insurance and the general reductions in the coverage of such insurance; 

WHEREAS, the Company and Indemnitee further recognize the substantial increase in corporate litigation in general, subjecting officers,
directors and employees to expensive litigation risks at the same time as the availability and coverage of liability insurance has been severely limited; and 

WHEREAS, the Company desires to attract and retain the services of highly qualified individuals such as Indemnitee to serve as officers,
directors or employees of the Company or any subsidiary and to indemnify such officers, directors and employees so as to provide them with the maximum protection permitted by law. 

NOW THEREFORE, in consideration for Indemnitee’s services as a director or officer of the Company or any subsidiary, the Company and
Indemnitee hereby agree as follows: 
 1. Indemnification. 

(a) Third Party Proceedings. The Company shall indemnify Indemnitee if Indemnitee is or was a party or is threatened to be made a party
to, or is otherwise involved (including involvement as a witness) in, any threatened, pending or completed action, suit, proceeding or any alternative dispute resolution mechanism, whether civil, criminal, administrative or investigative (other than
an action by or in the right of the Company) by reason of the fact that Indemnitee is or was a director or officer of the Company or any subsidiary of the Company, by reason of any action or inaction on the part of Indemnitee while a director or
officer of the Company or any subsidiary of the Company or by reason of the fact that Indemnitee, while serving as a director or officer of the Company or any subsidiary of the Company, is or was serving at the request of the Company or any
subsidiary of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement
actually and reasonably incurred by Indemnitee in connection with such action, suit or proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or any
subsidiary of the Company and, with respect to any criminal action or proceeding, had no reasonable cause to believe Indemnitee’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement or
conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best
interests of the Company or any subsidiary of the Company and, with respect to any criminal action or proceeding, had reasonable cause to believe that Indemnitee’s conduct was unlawful. 







 (b) Proceedings by or in the Right of the Company. The Company shall indemnify Indemnitee
if Indemnitee was or is a party or is threatened to be made a party to, or is otherwise involved (including involvement as a witness) in, any threatened, pending or completed action or suit by or in the right of the Company or any subsidiary of the
Company to procure a judgment in its favor by reason of the fact that Indemnitee is or was a director or officer of the Company or any subsidiary of the Company, by reason of any action or inaction on the part of Indemnitee while a director or
officer of the Company or any subsidiary of the Company or by reason of the fact that Indemnitee, while serving as a director or officer of the Company or any subsidiary of the Company, is or was serving at the request of the Company or any
subsidiary of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) and, to the fullest extent permitted by law, amounts
paid in settlement actually and reasonably incurred by Indemnitee in connection with the defense or settlement of such action or suit if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the
best interests of the Company or any subsidiary of the Company, except that no indemnification shall be made in respect of any claim, issue or matter as to which Indemnitee shall have been adjudged to be liable to the Company or any subsidiary of
the Company unless and only to the extent that the Court of Chancery of the State of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the
circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery of the State of Delaware or such other court shall deem proper. 

(c) Mandatory Payment of Expenses. To the extent that Indemnitee has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in subsections (a) and (b) of this Section 1, or in defense of any claim, issue or matter therein, Indemnitee shall be indemnified against expenses (including attorneys’ fees) actually and
reasonably incurred by Indemnitee in connection therewith. 
 2. Agreement to Serve. In consideration of the protection afforded by
this Agreement, if Indemnitee is a director of the Company, he or she agrees to serve at least for the six months after the effective date of this Agreement as a director and not to resign voluntarily during such period without the written consent
of a majority of the Board of Directors of the Company. If Indemnitee is an officer of the Company or any subsidiary of the Company not serving under an employment contract, he or she agrees to serve in such capacity at least for the balance of the
current fiscal year of the Company or such subsidiary of the Company and not to resign voluntarily during such period without the written consent of a majority of the Board of Directors of the Company. Following the applicable period set forth
above, Indemnitee agrees to continue to serve in such capacity at the will of the Company or any subsidiary of the Company (or under separate agreement, if such agreement exists) so long as he or she is duly appointed or elected and qualified in
accordance with the applicable provisions of the Bylaws of the Company or such subsidiary of the Company or until such time as he or she tenders his or her resignation in writing. Nothing contained in this Agreement is intended to create in
Indemnitee any right to continued employment.

 3. Expenses; Indemnification Procedure. 

(a) Advancement of Expenses. The Company shall advance all expenses incurred by Indemnitee in connection with the investigation,
defense, settlement or appeal of any civil or criminal action, suit or proceeding referenced in Section 1(a) or (b) (but not amounts actually paid in settlement of any such action, suit or proceeding). Indemnitee hereby undertakes to repay
such amounts advanced (without interest) only if, and to the extent that, it shall ultimately be determined that Indemnitee is not entitled to be indemnified by the Company as authorized hereby. 

(b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a condition precedent to his or her right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any claim made against Indemnitee for which indemnification will or could be sought under this Agreement. Notice to the Company shall be directed to the President of the Company
at the address shown on the signature page of this Agreement (or such other address as the Company shall designate in writing to Indemnitee). Notice shall be deemed received three (3) business days after the date postmarked if sent by domestic
certified or registered mail, properly addressed; or five (5) business days if sent by airmail to a country outside of North America; otherwise notice shall be deemed received when such notice shall actually be received by the Company. In
addition, Indemnitee shall give the Company such information and cooperation as it may reasonably require and as shall be within Indemnitee’s power. 

(c) Procedure. Any indemnification and advances provided for in Section 1 and this Section 3 shall be made no later than
thirty (30) days (or, in the case of an advance of expenses, twenty (20) days) after receipt of the written request of Indemnitee. Indemnitee may request indemnification at any time following the final disposition of a proceeding. If a
claim under this Agreement, under any statute or under any provision of the Company’s Certificate of Incorporation or Bylaws providing for indemnification is not paid in full by the Company within thirty (30) days (or, in the case of an
advance of expenses, twenty (20) days) after a written request for payment thereof has first been received by the Company, Indemnitee may, but need not, at anytime thereafter, bring an action against the Company to recover the unpaid amount of
the claim and, subject to Section 15 of this Agreement, Indemnitee shall also be entitled to be paid for the expenses (including attorneys’ fees) of bringing such action. If a determination by the Company that the director or officer is
entitled to indemnification pursuant to Section 1 is required, and the Company fails to respond within sixty (60) days to a written request for indemnity, the Company shall be deemed to have approved the request. It shall be a defense to
any such action (other than an action brought to enforce a claim for expenses incurred in connection with any action, suit or proceeding in advance of its final disposition) that Indemnitee has not met the standards of conduct which make it
permissible under applicable law for the Company to indemnify Indemnitee for the amount claimed. However, Indemnitee shall be entitled to receive interim payments of expenses pursuant to Section 3(a) unless and until such defense may be finally
adjudicated by court order or judgment from which no further right of appeal exists. It is the parties’ intention that if the Company contests Indemnitee’s right to indemnification, the question of Indemnitee’s right to
indemnification shall be for the court to decide, and neither the failure of the Company (including its Board of Directors, any committee or subgroup of the Board of Directors, independent legal counsel or its stockholders) to have made a
determination that indemnification of Indemnitee is proper in the circumstances because Indemnitee has met the applicable standard of conduct required by applicable law, nor an actual determination by the Company (including its Board of Directors,
any committee or subgroup of the Board of Directors, independent legal counsel or its stockholders) that Indemnitee has not met such applicable standard of conduct, shall be a defense to Indemnitee’s action for indemnification or create a
presumption that Indemnitee has or has not met the applicable standard of conduct. 

  
 -3- 








 (d) Notice to Insurers. If, at the time of the receipt of a notice of a claim pursuant to
Section 3(b), the Company has directors and officers liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective
policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies. 

(e) Selection of Counsel. In the event the Company shall be obligated under Section 3(a) to advance the expenses of any proceeding
against Indemnitee, the Company, if appropriate, shall be entitled to assume the defense of such proceeding, with counsel approved by Indemnitee, upon the delivery to Indemnitee of written notice of its election and approval of counsel by
Indemnitee. After the delivery of such notice, approval of such counsel by Indemnitee and retention of such counsel by the Company, the Company shall not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred by
Indemnitee with respect to the same proceeding, except as provided below. The Indemnitee shall have the right to employ his or her own counsel in any such proceeding at Indemnitee’s expense unless: (i) the employment of counsel by
Indemnitee has been previously authorized by the Company, (ii) Indemnitee shall have reasonably concluded that there may be a material conflict of interest between the Company and Indemnitee in the conduct of any such defense or (iii) the
Company shall not, in fact, have employed counsel to assume the defense of such proceeding, in each of which case the fees and expenses of Indemnitee’s counsel shall be at the expense of the Company. 

4. Additional Indemnification Rights; Nonexclusivity. 

(a) Scope. Notwithstanding any other provision of this Agreement, the Company hereby agrees to indemnify Indemnitee to the fullest
extent permitted by law, notwithstanding that such indemnification is not specifically authorized by the other provisions of this Agreement, by the Company’s Certificate of Incorporation or Bylaws or by statute. In the event of any change after
the date of this Agreement in any applicable law, statute or rule which expands the right of a Delaware corporation to indemnify a member of its board of directors or an officer or employee of the Company or any subsidiary of the Company, such
changes shall be, ipso facto, within the purview of Indemnitee’s rights and the Company’s obligations under this Agreement. In the event of any change in any applicable law, statute or rule which narrows the right of a Delaware corporation
to indemnify a member of its board of directors or an officer or employee of the Company or any subsidiary of the Company, such changes, to the extent not otherwise required by such law, statute or rule to be applied to this Agreement, shall have no
effect on this Agreement or the parties’ rights and obligations hereunder. 

  
 -4- 








 (b) Nonexclusivity. The indemnification provided by this Agreement shall not be deemed
exclusive of any rights to which Indemnitee may be entitled under the Company’s Certificate of Incorporation or Bylaws, any agreement, any vote of stockholders or disinterested directors, the General Corporation Law of the State of Delaware
(the “DGCL”) or otherwise, both as to action in Indemnitee’s official capacity and as to action in another capacity while holding such office. The indemnification provided under this Agreement shall continue as to Indemnitee for any
action taken or not taken while serving in an indemnified capacity even though he or she may have ceased to serve in such capacity at the time of any action, suit or other covered proceeding. 

5. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some
or a portion of the expenses, judgments, fines or penalties actually or reasonably incurred by him or her in the investigation, defense, appeal or settlement of any civil or criminal action, suit or proceeding, but not, however, for the total amount
thereof, the Company shall nevertheless indemnify Indemnitee for the portion of such expenses, judgments, fines or penalties to which Indemnitee is entitled. 

6. Contribution. To provide for just and equitable contribution when the indemnification provided for herein is held by a court of
competent jurisdiction to be unavailable to Indemnitee in whole or in part, it is agreed that, in such event, the Company shall, to the fullest extent permitted by law, contribute to the payment of Indemnitee’s losses with respect to any
proceeding, in an amount that is just and equitable in the circumstances; provided, that, without limiting the generality of the foregoing, such contribution shall not be required where such holding by the court is due to any limitation on
indemnification set forth in Section 11 (other than Section 11(f)). 
 7. Primacy of Indemnification. The Company hereby
acknowledges that Indemnitee may have certain rights to indemnification, advancement of expenses and/or insurance provided by one or more Indemnitee-related entities (as defined below), including, but not limited to, an umbrella policy
(collectively, the “Secondary Indemnification Sources”) which Indemnitee and the Secondary Indemnification Sources intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the
Company’s acknowledgement and agreement to the foregoing being a material condition to Indemnitee’s willingness to serve on the Board of Directors. The Company hereby agrees (i) that it is the indemnitor of first resort (i.e.,
its obligations to Indemnitee are primary and any obligation of the Secondary Indemnification Sources to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that the
Company shall be required to advance the full amount of expenses incurred by Indemnitee and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent permitted by the laws of the
State of Delaware and as required by the terms of this Agreement and the Certificate of Incorporation or Bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the
Secondary Indemnification Sources, and, (iii) that the Company irrevocably waives, relinquishes and releases the Secondary Indemnification Sources from any and all claims against the Secondary Indemnification Sources for contribution,
subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Secondary Indemnification Sources on behalf of Indemnitee with respect to any claim for which Indemnitee has sought
indemnification from the Company shall affect the foregoing and the Secondary Indemnification Sources shall have a right of contribution and/or be subrogated to the extent of such advancement or payment to all of the rights of recovery of Indemnitee
against the Company. The Company and Indemnitee agree that the Secondary Indemnification Sources are express third party beneficiaries of the terms of this Section 7. 

  
 -5- 








 The term “Indemnitee-related entities” means any corporation, limited liability
company, partnership, joint venture, trust, employee benefit plan or other enterprise (other than the Company or any other corporation, limited liability company, partnership, joint venture, trust, employee benefit plan or other enterprise for which
Indemnitee has agreed, on behalf of the Company or at the Company’s request, to serve as a director, officer, employee or agent and which service is covered by the indemnity described in this Agreement) from whom an Indemnitee may be entitled
to indemnification or advancement of expenses. 
 8. Mutual Acknowledgement. Both the Company and Indemnitee acknowledge that in
certain instances Federal law or applicable public policy may prohibit the Company from indemnifying its directors, officers and employees under this Agreement or otherwise. Indemnitee understands and acknowledges that the Company has undertaken or
may be required in the future to undertake with the Securities and Exchange Commission to submit the question of indemnification to a court in certain circumstances for a determination of the Company’s right under public policy to indemnify
Indemnitee. 
 9. Directors and Officers Liability Insurance. The Company shall, from time to time, make a good faith determination
whether or not it is practicable for the Company to obtain and maintain a policy or policies of insurance with reputable insurance companies providing the directors, officers and employees of the Company or any subsidiary of the Company with
coverage for losses from wrongful acts or to ensure the Company’s performance of its indemnification obligations under this Agreement. Among other considerations, the Company will weigh the costs of obtaining such insurance coverage against the
protection afforded by such coverage. In all policies of directors’ and officers’ liability insurance, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee the same rights and benefits as are accorded to the
most favorably insured of the Company’s directors, if Indemnitee is a director; or the most favorably insured of the Company’s officers, if Indemnitee is not a director of the Company but is an officer of the Company or any subsidiary of
the Company. Notwithstanding the foregoing, and subject to the Change in Control provisions of Section 24, the Company shall have no obligation to obtain or maintain such insurance if the Company determines in good faith that such insurance is
not reasonably available, if the premium costs for such insurance are disproportionate to the amount of coverage provided, if the coverage provided by such insurance is limited by exclusions so as to provide an insufficient benefit or if Indemnitee
is covered by similar insurance maintained by a subsidiary or parent of the Company. 

  
 -6- 








 10. Severability. Nothing in this Agreement is intended to require or shall be construed
as requiring the Company to do or fail to do any act in violation of applicable law. The Company’s inability, pursuant to court order, to perform its obligations under this Agreement shall not constitute a breach of this Agreement. The
provisions of this Agreement shall be severable as provided in this Section 10. If this Agreement or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify
Indemnitee to the fullest extent permitted by any applicable portion of this Agreement that shall not have been invalidated, and the balance of this Agreement not so invalidated shall be enforceable in accordance with its terms. 

11. Exceptions. Any other provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement: 
 (a) to indemnify or advance expenses to Indemnitee with respect to proceedings or claims initiated or brought voluntarily
by Indemnitee and not by way of defense, except with respect to proceedings brought to establish or enforce a right to indemnification under this Agreement or any other statute or law or otherwise as required under Section 145 of the DGCL, but
such indemnification or advancement of expenses may be provided by the Company in specific cases if the Board of Directors has approved the initiation or bringing of such suit; or 

(b) except as otherwise provided in Section 15, to indemnify Indemnitee for any expenses incurred by Indemnitee with respect to any
proceeding instituted by Indemnitee to enforce or interpret this Agreement; or 
 (c) to indemnify Indemnitee for expenses or liabilities of
any type whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or penalties, and amounts paid in settlement) which have been paid directly to Indemnitee by an insurance carrier under a policy of directors and officers
liability insurance maintained by the Company, its parent or any of its subsidiaries or under any statute, indemnity provisions, vote or otherwise; or 

(d) for any reimbursement of the Company by such person of any bonus or other incentive-based or equity-based compensation or of any profits
realized by such person from the sale of securities of the Company, as required in each case under the Securities Exchange Act of 1934, as amended, or any similar successor statute (the “Exchange Act”) (including any such reimbursements
that arise from an accounting restatement of the Company pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by such person
of securities in violation of Section 306 of the Sarbanes-Oxley Act), if such person is held liable therefor (including pursuant to any settlement arrangements); or 

(e) to indemnify Indemnitee for an accounting or disgorgement of profits pursuant to Section 16(b) of the Exchange Act, or similar
provisions of federal, state or local statutory law or common law, if such person is held liable therefor (including pursuant to any settlement arrangements); or 

(f) to indemnify Indemnitee if prohibited by applicable law. 

  
 -7- 








 12. Construction of Certain Terms and Phrases. 

(a) For purposes of this Agreement, references to the “Company” shall not include any constituent corporation absorbed in a
consolidation or merger with the Company. 
 (b) For purposes of this Agreement, references to “other enterprises” shall include
employee benefit plans; and references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer,
employee or agent with respect to an employee benefit plan or its participants or beneficiaries; and if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in the interest of the participants and beneficiaries of an
employee benefit plan, Indemnitee shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this Agreement. 

(c) For purposes of this Agreement, a “change in control of the Company” shall be deemed to have occurred if after the effective
date: (i) as the result of, or in connection with, any cash tender or exchange offer, merger or other business combination, sale of all or substantially all of the assets or contested election, or any combination of the foregoing transactions,
less than a majority of the combined voting power of the then-outstanding securities of the Company or any successor corporation or entity entitled to vote generally in the election of the directors of the Company or such other corporation or entity
after such transaction is held in the aggregate by the holders of the securities of the Company entitled to vote generally in the election of directors of the Company immediately prior to such transaction; (ii) any person or entity, including a
“group” (as defined in Section 13(d)(3) of the Exchange Act), other than the Company, any wholly-owned subsidiary of the Company, any employee benefit plan of the Company or any subsidiary of the Company, becomes the beneficial owner
(as defined in Rule 13d-3 under the Exchange Act) of securities of the Company having 50% or more of the combined voting power of the then-outstanding securities of the Company that may be cast for the election of directors of the Company (other
than as a result of an issuance of securities initiated by the Company in the ordinary course of business); (iii) during any period of two consecutive years, individuals who at the beginning of any such period constitute the directors of the
Company cease for any reason to constitute at least a majority thereof unless the election, or the nomination for election by the stockholders of the Company, of each new director of the Company during such period was approved by a vote of at least
two-thirds of such directors of the Company then still in office who were directors of the Company at the beginning of any such period; or (iv) the stockholders of the Company approve a plan of complete liquidation of the Company. 

13. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall constitute an original. 

14. Successors and Assigns. This Agreement shall be binding upon the Company and its successors and assigns and shall inure to the
benefit of Indemnitee and Indemnitee’s estate, heirs, legal representatives and assigns. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all or
a substantial part of the business and/or assets of the Company, by written agreement in form and substance satisfactory to Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the
Company would be required to perform if no such succession had taken place. 

  
 -8- 








 15. Attorneys’ Fees. In the event that any action is instituted by Indemnitee under
this Agreement to enforce or interpret any of the terms hereof, Indemnitee shall be entitled to be paid all court costs and expenses, including reasonable attorneys’ fees, incurred by Indemnitee with respect to such action, to the maximum
extent permitted by the laws of the State of Delaware. In the event of an action instituted by or in the name of the Company under this Agreement or to enforce or interpret any of the terms of this Agreement, Indemnitee shall be entitled to be paid
all court costs and expenses, including attorneys’ fees, incurred by Indemnitee in defense of such action (including with respect to Indemnitee’s counterclaims and cross-claims made in such action), to the maximum extent permitted by the
laws of the State of Delaware. 
 16. Notice. Except as provided in Section 3(b), all notices, requests, demands and other
communications under this Agreement shall be in writing and shall be deemed duly given (i) if delivered by hand and receipted for by the party addressee, on the date of such receipt, or (ii) if mailed by domestic certified or registered
mail with postage prepaid, on the third business day after the date postmarked. Addresses for notice to either party are as shown on the signature page of this Agreement, or as subsequently modified by written notice. 

17. Consent to Jurisdiction. The Company and Indemnitee each hereby irrevocably consent to the jurisdiction of the courts of the State
of Delaware for all purposes in connection with any action or proceeding which arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be brought only in the state courts of the State of Delaware.

 18. Choice of Law. This Agreement shall be governed by and its provisions construed in accordance with the laws of the State of
Delaware, as applied to contracts between Delaware residents entered into and to be performed entirely within Delaware without regard to the conflict of law principles thereof. 

19. Period of Limitations. No legal action shall be brought and no cause of action shall be asserted by or in the right of the Company
against Indemnitee, Indemnitee’s estate, spouse, heirs, executors or personal or legal representatives after the expiration of two years from the date of accrual of such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal action within such two-year period; provided, however, that if any shorter period of limitations is otherwise applicable to any such cause of action, such shorter
period shall govern. 
 20. Subrogation. In the event of payment under this Agreement, the Company shall be subrogated to the extent
of such payment to all of the rights of recovery of Indemnitee, who shall execute all documents required and shall do all acts that may be necessary to secure such rights and to enable the Company effectively to bring suit to enforce such rights.

 21. Retroactivity. This Agreement shall be deemed to have been in effect during all periods that Indemnitee was a director,
officer or employee of the Company, regardless of the date of this Agreement. 

  
 -9- 








 22. Amendment and Termination. No amendment, modification, termination or cancellation of
this Agreement shall be effective unless it is in writing signed by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not
similar), nor shall such waiver constitute a continuing waiver. 
 23. Integration and Entire Agreement. Subject to the provisions of
Section 4, this Agreement sets forth the entire understanding between the parties hereto and supersedes and merges all previous written and oral negotiations, commitments, understandings and agreements relating to the subject matter hereof
between the parties hereto. 
 24. Change in Control. Notwithstanding any provision of this Agreement to the contrary, following the
occurrence of a change in control of the Company: 
 (a) all determinations with respect to Indemnitee’s entitlement to indemnification
and advancement of expenses shall, if requested by Indemnitee, be made by independent legal counsel selected by Indemnitee and reasonably acceptable to the Company, the determination of which shall be provided in writing to the Company and
Indemnitee; 
 (b) Indemnitee shall be entitled to control the defense of any action, suit, proceeding or other matter with counsel of its
own choosing reasonably acceptable to the Company, the reasonable fees and expenses of which shall be paid by the Company promptly as incurred; provided that the Company shall not be liable for any settlement of any such action, suit, proceeding or
other matter by Indemnitee effected without the Company’s written consent, which consent shall not be unreasonably withheld, delayed or conditioned; 

(c) the Company shall, for a period of six years after the date of the change in control, maintain in effect with reputable insurers a policy
or policies of directors and officers liability insurance substantially equivalent (in terms of policy terms and levels of coverage) to the policy or policies maintained by the Company as of the date of the change in control with respect to claims
arising from or relating to actions or omissions, or alleged actions or omissions, occurring on or prior to the date of the change in control; and 

(d) the Company shall, for a period of six years after the date of the change in control, maintain in effect the provisions in its Certificate
of Incorporation and Bylaws providing for exculpation of director, officer and employee liability and indemnification to the fullest extent permitted from time to time under the laws of the State of Delaware, which provisions shall not be amended
except as required by applicable law or to make changes permitted by applicable law that would enlarge the scope of the Indemnitee’s indemnification rights hereunder.
