 Exhibit 10.21 

Nutanix, Inc. 
 Change of
Control and Severance Policy 
 This Change of Control and Severance Policy (the “Policy”) is designed to provide certain protections
to a select group of key employees of Nutanix, Inc. (“Nutanix” or the “Company”) or any of its subsidiaries in connection with a change of control of Nutanix or in connection with the involuntary termination of
their employment under the circumstances described in this Policy. The Policy is designed to be an “employee welfare benefit plan” (as defined in Section 3(1) of the Employee Retirement Income Security Act of 1974, as amended
(“ERISA”)), and this document is both the formal plan document and the required summary plan description for the Policy. 
 Eligible
Employee: An individual is only eligible for protection under this Policy if he or she is an Eligible Employee and complies with its terms (including any terms in the employee’s Participation Agreement (as defined below)). To be an
“Eligible Employee,” an employee must (a) have been designated by the Compensation Committee of the Board (the “Compensation Committee”) as eligible to participate in the Policy and (b) have executed a participation
agreement in the form attached hereto as Exhibit A (a “Participation Agreement”).
 Policy Benefits: An Eligible Employee
will be eligible to receive the payments and benefits set forth in this Policy and his or her Participation Agreement if his or her employment with Nutanix or any of its subsidiaries terminates as a result of a Qualified Termination. All
benefits under this Policy payable on a Qualified Termination will be subject to the Eligible Employee’s compliance with the Release Requirement and any timing modifications required to avoid adverse taxation under Section 409A.

Equity Vesting: On a Qualified Termination, the applicable percentage (set forth in an Eligible Employee’s Participation Agreement) of the
then-unvested time-based shares subject to each of the Eligible Employee’s then-outstanding equity awards will immediately vest and, in the case of options and stock appreciation rights, will become exercisable (for avoidance of doubt, no more
than 100% of the shares subject to the outstanding portion of an equity award may vest and become exercisable under this provision). Acceleration under this Policy will not apply to any equity awards subject to outstanding performance-based
vesting. For clarity, if an equity award was subject to a threshold performance-based vesting schedule and a time-based vesting schedule after the performance objective was achieved, then such an equity award would be (i) a time-based vesting
award on or after the performance objective was achieved and eligible for acceleration under this Policy and (ii) a performance-based vesting award prior to the performance objective being achieved and therefore ineligible for acceleration under
this Policy. Further, any award with outstanding performance-based vesting that by its terms converts to a time-based vesting award upon a change of control transaction will not be eligible for any acceleration under this Policy. Any
restricted stock units, restricted stock and/or similar full value awards that vest under this paragraph will be settled on the 61st day following the Eligible Employee’s Qualified
Termination. 
 Salary Severance: On a Qualified Termination, an Eligible Employee will be eligible to receive salary severance payment(s) equal to
the applicable percentage (set forth in his or her Participation Agreement) of his or her Base Salary. The Eligible Employee’s salary severance payment(s) will be paid in cash at the time(s) specified in his or her Participation
Agreement.
 Bonus Severance: On a Qualified Termination, an Eligible Employee will be eligible to receive bonus severance payment(s) with respect to
his or her annual bonus in the amount set forth in 

 
his or her Participation Agreement. The Eligible Employee’s bonus severance payment(s) will be paid in cash at the time(s) specified in his or her Participation Agreement.

COBRA Payment: Upon a Qualified Termination, if an Eligible Employee makes a valid election under COBRA to continue his or her health coverage, the
Company will pay or reimburse the Eligible Employee for the cost of such continuation coverage for the Eligible Employee and any eligible dependents that were covered under the Company’s health care plans immediately prior to the date of his or
her eligible termination until the earliest of (a) the end of the applicable period set forth in the Eligible Employee’s Participation Agreement, (b) the date upon which the Eligible Employee and/or the Eligible Employee’s eligible
dependents become covered under similar plans or (c) the date upon which the Eligible Employee ceases to be eligible for coverage under COBRA (the “COBRA Coverage”).

Death of Eligible Employee: If the Eligible Employee dies before all payments or benefits he or she is entitled to receive under this Policy have been
paid, such unpaid amounts will be paid to his or her designated beneficiary, if living, or otherwise to his or her personal representative in a lump-sum payment as soon as possible following his or her death. 

Recoupment: If the Company discovers after the Eligible Employee’s receipt of payments or benefits under this Policy that grounds for the
termination of the Eligible Employee’s employment for Cause existed, then the Eligible Employee will not receive any further payments or benefits under this Policy and, to the extent permitted under applicable laws, will be required to repay to
the Company any payments or benefits he or she received under the Policy (or any financial gain derived from such payments or benefits). 

Release: The Eligible Employee’s receipt of any payments or benefits upon his or her Qualified Termination under this Policy is subject to
the Eligible Employee signing and not revoking the Company’s then-standard separation agreement and release of claims (which may include an agreement not to disparage the Company, non-solicit provisions, and other standard terms and conditions)
(the “Release” and such requirement, the “Release Requirement”), which must become effective and irrevocable no later than the 60th day following the Eligible Employee’s Qualified Termination (the
“Release Deadline”). If the Release does not become effective and irrevocable by the Release Deadline, the Eligible Employee will forfeit any right to payments or benefits under this Policy. In no event will payments or
benefits under the Policy be paid or provided until the Release actually becomes effective and irrevocable. Notwithstanding any other payment schedule set forth in this Policy or the Eligible Employee’s Participation Agreement, none of the
payments and benefits payable upon such Eligible Employee’s Qualified Termination under this Policy will be paid or otherwise provided prior to the 60th day following the Eligible Employee’s Qualified Termination. Except as otherwise
set forth in an Eligible Employee’s Participation Agreement or to the extent that payments are delayed under the paragraph below entitled “Section 409A,” on the first regular payroll pay day following the 60th day following the
Eligible Employee’s Qualified Termination, the Company will pay or provide the Eligible Employee the payments and benefits that the Eligible Employee would otherwise have received under this Policy on or prior to such date, with the balance of
such payments and benefits being paid or provided as originally scheduled. 
 Section 409A: The Company intends that all payments and benefits
provided under this Policy or otherwise are exempt from, or comply with, the requirements of Section 409A of the Code and any guidance promulgated thereunder (collectively, “Section 409A”) so that none of the payments or benefits
will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted in accordance with this intent. No payment or benefits to be paid to an Eligible Employee, if any, under this Policy or otherwise,
when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A (together, the “Deferred Payments”) will be paid or

  
 2 

 
otherwise provided until such Eligible Employee has a “separation from service” within the meaning of Section 409A. If, at the time of the Eligible Employee’s termination of
employment, the Eligible Employee is a “specified employee” within the meaning of Section 409A, then the payment of the Deferred Payments will be delayed to the extent necessary to avoid the imposition of the additional tax imposed under
Section 409A, which generally means that the Eligible Employee will receive payment on the first payroll date that occurs on or after the date that is 6 months and 1 day following his or her termination of employment. The Company reserves the
right to amend the Policy as it deems necessary or advisable, in its sole discretion and without the consent of any Eligible Employee or any other individual, to comply with any provision required to avoid the imposition of the additional tax
imposed under Section 409A or to otherwise avoid income recognition under Section 409A prior to the actual payment of any benefits or imposition of any additional tax. Each payment, installment, and benefit payable under this Policy
is intended to constitute a separate payment for purposes of U.S. Treasury Regulation Section 1.409A-2(b)(2). In no event will the Company reimburse any Eligible Employee for any taxes that may be imposed on him or her as a result of
Section 409A.
 Parachute Payments: 

Reduction of Severance Benefits. Notwithstanding anything set forth herein to the contrary, if any payment or benefit that
an Eligible Employee would receive from the Company or any other party whether in connection with the provisions herein or otherwise (the “Payment”) would (a) constitute a “parachute payment” within the meaning of
Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (b) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then
such Payment will be equal to the Best Results Amount. The “Best Results Amount” will be either (x) the full amount of such Payment or (y) such lesser amount as would result in no portion of the Payment being subject to
the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local employment taxes, income taxes and the Excise Tax, results in the Eligible Employee’s receipt, on an after-tax basis, of the greater
amount notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting parachute payments is necessary so that the Payment equals the Best Results Amount, reduction will
occur in the following order: reduction of cash payments; cancellation of accelerated vesting of stock awards; reduction of employee benefits. In the event that acceleration of vesting of stock award compensation is to be reduced, such
acceleration of vesting will be cancelled in the reverse order of the date of grant of the Eligible Employee’s equity awards unless the Eligible Employee elects in writing a different order for cancellation. The Eligible Employee will be
solely responsible for the payment of all personal tax liability that is incurred as a result of the payments and benefits received under this Policy, and the Eligible Employee will not be reimbursed by the Company for any such payments. 

Determination of Excise Tax Liability. The Company will select a professional services firm to make all of the
determinations required to be made under these paragraphs relating to parachute payments. The Company will request that firm provide detailed supporting calculations both to the Company and the Eligible Employee prior to the date on which the
event that triggers the Payment occurs if administratively feasible, or subsequent to such date if events occur that result in parachute payments to the Eligible Employee at that time. For purposes of making the calculations required under
these paragraphs relating to parachute payments, the firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith determinations concerning the application of the Code. The

  
 3 

 
Company and the Eligible Employee will furnish to the firm such information and documents as the firm may reasonably request in order to make a determination under these paragraphs relating to
parachute payments. The Company will bear all costs the firm may reasonably incur in connection with any calculations contemplated by these paragraphs relating to parachute payments. Any such determination by the firm will be binding upon
the Company and the Eligible Employee, and the Company will have no liability to the Eligible Employee for the determinations of the firm. 

Administration: The Policy will be administered by the Compensation Committee or its delegate (in each case, an
“Administrator”). The Administrator will have full discretion to administer and interpret the Policy. Any decision made or other action taken by the Administrator with respect to the Policy and any interpretation by the
Administrator of any term or condition of the Policy, or any related document, will be conclusive and binding on all persons and be given the maximum possible deference allowed by law. The Administrator is the “plan administrator” of
the Policy for purposes of ERISA and will be subject to the fiduciary standards of ERISA when acting in such capacity.
 Attorneys Fees: The
Company and each Eligible Employee will bear their own attorneys’ fees incurred in connection with any disputes between them. 
 Exclusive
Benefits: Except as may be set forth in an Eligible Employee’s Participation Agreement, this Policy is intended to be the only agreement between the Eligible Employee and the Company regarding any change of control payments or benefits
to be paid to the Eligible Employee on account of a termination of employment related to a Change of Control. Accordingly, by executing a Participation Agreement, an Eligible Employee hereby forfeits and waives any rights to any change of
control and/or any other double-trigger change of control benefits set forth in any employment agreement, offer letter, and/or equity award agreement, except as set forth in this Policy and in the Eligible Employee’s Participation Agreement.

 Tax Withholding: All payments and benefits under this Policy will be paid less applicable withholding taxes. The Company is authorized to
withhold from any payments or benefits all federal, state, local and/or foreign taxes required to be withheld therefrom and any other required payroll deductions. The Company will not pay any Eligible Employee’s taxes arising from or
relating to any payments or benefits under this Policy. 
 Amendment or Termination: The Board or the Compensation Committee may amend or terminate
the Policy at any time, without advance notice to any Eligible Employee or other individual and without regard to the effect of the amendment or termination on any Eligible Employee or on any other individual. Notwithstanding the preceding, no
amendment or termination of the Policy will be made if such amendment or reduction would reduce the benefits provided hereunder or impair an Eligible Employee’s eligibility under the Policy (unless the affected Eligible Employee consents to
such amendment or termination), except that any amendment or termination that impacts the Equity Vesting with respect to future equity awards requires notice in writing 3 months prior to the effective date of the amendment or termination and does
not require an Eligible Employee’s consent. Any action to amend or terminate the Policy will be taken in a non-fiduciary capacity. 
 Claims
Procedure: Any Eligible Employee who believes he or she is entitled to any payment under the Policy may submit a claim in writing to the Administrator. If the claim is denied (in full or in part), the claimant will be provided a
written notice explaining the specific reasons for the denial and referring to the provisions of the Policy on which the denial is based. The notice will also describe any additional information needed to support the claim and the Policy’s
procedures for appealing the denial. The denial notice will be provided within 90 days after the claim is received. If special circumstances require an extension of time (up to 90 days), written

  
 4 

 
notice of the extension will be given within the initial 90-day period. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which
the Administrator expects to render its decision on the claim. 
 Appeal Procedure: If the claimant’s claim is denied, the claimant (or his or
her authorized representative) may apply in writing to the Administrator for a review of the decision denying the claim. Review must be requested within 60 days following the date the claimant received the written notice of their claim denial
or else the claimant loses the right to review. The claimant (or representative) then has the right to review and obtain copies of all documents and other information relevant to the claim, upon request and at no charge, and to submit issues
and comments in writing. The Administrator will provide written notice of the decision on review within 60 days after it receives a review request. If additional time (up to 60 days) is needed to review the request, the claimant
(or representative) will be given written notice of the reason for the delay. This notice of extension will indicate the special circumstances requiring the extension of time and the date by which the Administrator expects to render its
decision. If the claim is denied (in full or in part), the claimant will be provided a written notice explaining the specific reasons for the denial and referring to the provisions of the Policy on which the denial is based. The notice
will also include a statement that the claimant will be provided, upon request and free of charge, reasonable access to, and copies of, all documents and other information relevant to the claim and a statement regarding the claimant’s right to
bring an action under Section 502(a) of ERISA. 
 Successors: Any successor to the Company of all or substantially all of the Company’s business
and/or assets (whether direct or indirect and whether by purchase, merger, consolidation, liquidation or other transaction) will assume the obligations under the Policy and agree expressly to perform the obligations under the Policy in the same
manner and to the same extent as the Company would be required to perform such obligations in the absence of a succession. For all purposes under the Policy, the term “Company” will include any successor to the Company’s business
and/or assets which becomes bound by the terms of the Policy by operation of law, or otherwise. 
 Applicable Law: The provisions of the Policy will
be construed, administered, and enforced in accordance with ERISA and, to the extent applicable, the internal substantive laws of the state of California (but not its conflict of laws provisions). 

Definitions: Unless otherwise defined in an Eligible Employee’s Participation Agreement, the following terms will have the following meanings
for purposes of this Policy and the Eligible Employee’s Participation Agreement: 
 “Base Salary” means the Eligible
Employee’s annual base salary as in effect immediately prior to his or her Qualified Termination (or if the termination is due to a resignation for Good Reason based on a material reduction in base salary, then the Eligible Employee’s
annual base salary in effect immediately prior to such reduction) or, if greater, at the level in effect immediately prior to the Change of Control.

“Board” means the Board of Directors of the Company. 

“Cause” means: 
  

	 	(i)	Eligible Employee’s willful failure to perform his or her duties and responsibilities to the Company or Eligible Employee’s violation of any written Company policy; 

  
 5 

	 	(ii)	Eligible Employee’s commission of any act of fraud, embezzlement, dishonesty or any other willful misconduct that has caused or is reasonably expected to result in injury to the Company; 

 

	 	(iii)	Eligible Employee’s unauthorized use or disclosure of any proprietary information or trade secrets of the Company or any other party to whom the Participant owes an obligation of nondisclosure as a result of his or
her relationship with the Company; or 

  

	 	(iv)	Eligible Employee’s material breach of any of his or her obligations under any written agreement or covenant with the Company. 

The determination as to whether Eligible Employee’s employment has been terminated for Cause shall be made in good faith by the Company
and shall be final and binding on the Eligible Employee. The foregoing definition does not in any way limit the Company’s ability to terminate an Eligible Employee’s employment relationship at any time, and the term “Company”
will be interpreted to include any subsidiary, parent, affiliate, or any successor thereto, if appropriate. 
 “Change of
Control” means the occurrence of any of the following events: 
  

	 	(i)	change in the ownership of the Company which occurs on the date that any one person, or more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together
with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the Company; provided, however, that for purposes of this subsection, the acquisition of additional stock by any one Person, who
is considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will not be considered a Change of Control. Further, if the stockholders of the Company immediately before such change in ownership continue to
retain immediately after the change in ownership, in substantially the same proportions as their ownership of shares of the Company’s voting stock immediately prior to the change in ownership, direct or indirect beneficial ownership of fifty
percent (50%) or more of the total voting power of the stock of the Company or of the ultimate parent entity of the Company, such event shall not be considered a Change of Control under this subsection (i). For this purpose, indirect beneficial
ownership shall include, without limitation, an interest resulting from ownership of the voting securities of one or more corporations or other business entities which own the Company, as the case may be, either directly or through one or more
subsidiary corporations or other business entities; or 

  

	 	(ii)	A change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during any twelve (12) month period by directors whose appointment or election is not
endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this subsection (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control
of the Company by the same Person will not be considered a Change of Control; or 

  

	 	(iii)	 A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that any
Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross fair market value equal to or more than fifty percent
(50%) of the total gross fair 

  
 6 

	 	
market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection (iii), the following will not
constitute a change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company
to: (1) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of the total value or voting power of which is owned, directly or
indirectly, by the Company, (3) a Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least fifty percent (50%) of the total
value or voting power of which is owned, directly or indirectly, by a Person described in this subsection (iii)(B)(3). For purposes of this subsection (iii), gross fair market value means the value of the assets of the Company, or the value of the
assets being disposed of, determined without regard to any liabilities associated with such assets. 

 For purposes of this
definition, persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 

Notwithstanding the foregoing, a transaction will not be a Change of Control unless the transaction qualifies as a change in control event
within the meaning of Section 409A (as defined below). 
 Further and for the avoidance of doubt, a transaction will not constitute a Change
of Control if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the
Company’s securities immediately before such transaction. 
 “Change of Control Period” will mean the period beginning
3 months prior to a Change of Control and ending 12 months following a Change of Control. 
 “COBRA” means the Consolidated
Omnibus Budget Reconciliation Act of 1985, as amended. 
 “Code” means the Internal Revenue Code of 1986, as amended. 

“Disability” means the total and permanent disability as defined in Section 22(e)(3) of the Code unless the Company maintains
a long-term disability plan at the time of the Eligible Employee’s termination, in which case, the determination of disability under such plan also will be considered “Disability” for purposes of this Policy. 

“Exchange Act” means the Securities and Exchange Act of 1934, as amended. 

“Good Reason” means the Eligible Employee’s termination of his or her employment in accordance with the next sentence
after the occurrence of one or more of the following events without the Eligible Employee’s express written consent: 
  

	 	(i)	a material reduction of the Eligible Employee’s duties, authorities, or responsibilities relative to the Eligible Employee’s duties, authorities, or responsibilities in effect immediately prior to such
reduction; 

  
 7 

	 	(ii)	a material reduction by the Company in the Eligible Employee’s rate of annual base salary; provided, however, that, a reduction of annual base salary that also applies to substantially all other similarly situated
employees of the Company will not constitute “Good Reason”; 

  

	 	(iii)	a material change in the geographic location of the Eligible Employee’s primary work facility or location; provided, that a relocation of less than 35 miles from the Eligible Employee’s then present location
will not be considered a material change in geographic location; or 

  

	 	(iv)	the failure of the Company to obtain from any successor or transferee of the Company an express written and unconditional assumption of the Company’s obligations to the Eligible Employee under this
Policy.

 In order for the Eligible Employee’s termination of his or her employment to be for Good Reason, the Eligible
Employee must not terminate employment with the Company without first providing the Company with written notice of the acts or omissions constituting the grounds for “Good Reason” within 90 days of the initial existence of the grounds for
“Good Reason” and a cure period of 30 days following the date of written notice (the “Cure Period”), such grounds must not have been cured during such time, and the Eligible Employee must terminate his or her employment
within 30 days following the Cure Period. 
 “Qualified Termination” means a termination of the Eligible Employee’s
employment either (A) by the Company other than for Cause, death, or Disability or (B) by the Eligible Employee for Good Reason, in either case, during the Change of Control Period.

 Statement of ERISA Rights: 

Eligible Employees have certain rights and protections under ERISA: 

They may examine (without charge) all Policy documents, including any amendments and copies of all documents filed with the U.S. Department of
Labor, such as the Policy’s annual report (Internal Revenue Service Form 5500). These documents are available for review in the Company’s Human Resources Department. 

They may obtain copies of all Policy documents and other Policy information upon written request to the Plan Administrator. A reasonable
charge may be made for such copies. 
 In addition to creating rights for Eligible Employees, ERISA imposes duties upon the people who are
responsible for the operation of the Policy. The people who operate the Policy (called “fiduciaries”) have a duty to do so prudently and in the interests of Eligible Employees. No one, including the Company or any other person,
may fire or otherwise discriminate against an Eligible Employee in any way to prevent them from obtaining a benefit under the Policy or exercising rights under ERISA. If an Eligible Employee’s claim for a severance benefit is denied, in
whole or in part, they must receive a written explanation of the reason for the denial. An Eligible Employee has the right to have the denial of their claim reviewed. (The claim review procedure is explained above.) 

Under ERISA, there are steps Eligible Employees can take to enforce the above rights. For instance, if an Eligible Employee requests
materials and does not receive them within 30 days, they may file suit in a federal court. In such a case, the court may require the Administrator to provide the materials and to pay the Eligible Employee up to $110 a day until they
receive the materials, unless the materials were not sent because of reasons beyond the control of the Plan Administrator. If an Eligible Employee has a claim which is denied or ignored, in whole or in part, he or she may file suit in a state
or federal court. If it should happen that an Eligible Employee is discriminated against for asserting their rights, he or she may seek assistance from the U.S. Department of Labor, or may file suit in a federal court. 

In any case, the court will decide who will pay court costs and legal fees. If the Eligible Employee is successful, the court may order
the person sued to pay these costs and fees. If the Eligible Employee loses, the court may order the Eligible Employee to pay these costs and fees, for example, if it finds that the claim is frivolous. 

If an Eligible Employee has any questions regarding the Policy, please contact the Plan Administrator. If an Eligible Employee has any
questions about this statement or about their rights under ERISA, they may contact the nearest area office of the Employee Benefits Security Administration (formerly the Pension and Welfare Benefits Administration), U.S. Department of Labor, listed
in the telephone directory, or the Division of Technical Assistance and Inquiries, Employee Benefits Security 

  
 9 

 
Administration, U.S. Department of Labor, 200 Constitution Avenue, N.W. Washington, D.C. 20210. An Eligible Employee may also obtain certain publications about their rights and
responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

 TIER 1 ELIGIBLE EMPLOYEE 

EXHIBIT A 
 Change
of Control and Severance Policy 
 Participation Agreement 

This Participation Agreement (“Agreement”) is made and entered into by and between [NAME] on the one hand, and Nutanix, Inc.
(the “Company”) on the other. 
 You have been designated as eligible to participate in the Policy, a copy of which is
attached hereto, under which you are eligible to receive the following payments and benefits upon a Qualified Termination, subject to the terms and conditions of the Policy. 

Qualified Termination 
 If you incur a
Qualified Termination, you will be entitled to the following benefits, subject to your compliance with the Policy: 
  

	 	•	 	Equity Vesting: Your equity vesting benefit will be 100%. For clarity, no accelerated vesting will apply to performance-based shares. 

 

	 	•	 	Salary Severance: Your percentage of Base Salary will be 100%, payable in a lump-sum on the first regular payroll pay day following the Release Deadline (subject to any delay required by Section 409A).

  

	 	•	 	Bonus Severance: You will receive a lump-sum payment equal to 100% of your target annual bonus as in effect for the fiscal year in which your Qualified Termination occurs. Amount will be payable on the first
regular payroll pay day following the Release Deadline subject to any delay required by Section 409A). 

  

	 	•	 	COBRA Payment: The Company shall pay or reimburse you for your COBRA continuation coverage for up to 12 months. 

Other Provisions 
 You agree that the
Policy and the Agreement constitute the entire agreement of the parties hereto and supersede in their entirety all prior representations, understandings, undertakings or agreements (whether oral or written and whether expressed or implied) of the
parties, and will specifically supersede any change of control provisions (including termination of employment related to a change of control) of any offer letter, employment agreement, or equity award agreement entered into between you and the
Company. 
 Further, Participant agrees that any awards with outstanding performance-based vesting that convert to time-based vesting shares
upon a change of control by their terms (including, but not limited to, any performance-based Xi restricted stock units granted April 27, 2016) will not be subject to any accelerated Equity Vesting under the Policy and this Agreement. 

This Agreement may be executed in counterparts, each of which will be deemed an original, but all of which together will constitute one and
the same instrument.

businesses or operations as currently conducted, except such licenses, permits, certificates, registrations, approvals, consents
and authorizations the failure of which to obtain would not have a material adverse effect on the business, properties, operations,
financial condition or results of operations of the Company, and the Company has not received any notice of proceedings relating
to the revocation, modification or suspension of any Permits and, to the Company’s Knowledge, there exists no circumstance
which would lead it to believe that such proceedings are reasonably likely.

 

5.12.Insurance.
 The Company maintains insurance of the type and in the amount reasonably adequate for its business, including, but not
limited to, insurance covering all real and personal property owned or leased by the Company against theft, damage, destruction,
acts of vandalism and all other risks customarily insured against by similarly situated companies, all of which insurance is in
full force and effect.

 

5.13.Changes.
Since the Company filed its Form 10-Q on August 11 2016, (i) there has not been any Company development that has not otherwise
been publicly disclosed that would have or could reasonably be expected to have a material adverse effect on the business, properties,
financial condition or operating results of the Company, as such business is presently conducted, (ii) the Company has not, to
the extent material to the Company, incurred any debts, obligations or liabilities, absolute, accrued or contingent, whether due

mortgaged, pledged or subjected to lien, charge, security interest or other encumbrance any of its assets, tangible or intangible,
(iv) the Company has not, to the extent material to the Company, waived any debt owed to the Company or its subsidiaries, (v)
the Company has not, to the extent material to the Company, satisfied or discharged any lien, claim, or encumbrance or paid any
obligation other than in the ordinary course of business, (vi) the Company has not, to the extent material to the Company, declared
or paid any dividends, (vii) the Company has not, to the extent material to the Company, entered into any transaction other than
in the usual and ordinary course of business, (viii) the Company has not entered into or terminated or contemplated entering into
or terminating any contract filed as an exhibit to the Company’s SEC Reports (defined below), and (ix) there has not been
any change in the assets, liabilities, financial condition or operating results of the Company from that reflected in the consolidated

5.14.Reports
and Financial Statements; Internal Controls.

 

(a)
Prior to the execution hereof, the Company has delivered to the Purchaser true and complete copies of the Company’s most
recently filed Form 10-K and the Proxy Statement in connection with the Company’s 2016 Annual Meeting of Stockholders and
all Forms 10-Q and 8-K filed by the Company with the SEC after January 1, 2016, in each case without exhibits thereto (the “SEC
Reports”). As of their respective filing dates, the SEC Reports were prepared in all material respects in accordance
with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the SEC
thereunder applicable to such SEC Reports. The SEC Reports, as they may be updated by any supplement or amendment to an SEC Report,
do not contain any untrue statements of a material fact and do not omit to state a material fact necessary to make the statements
therein, in light of the circumstances under which they were made, not misleading. The audited consolidated financial statements
and unaudited interim financial statements of the Company included in the SEC Reports (i) complied as to form in all material
respects with the published rules and regulations of the SEC with respect thereto, (ii) were prepared in accordance with United
States generally accepted accounting principles (“GAAP”) applied on a consistent basis (except as may be indicated
therein or in the notes thereto), and (iii) fairly present, in all material respects, the financial position of the Company as
at the dates thereof and the results of its operations and cash flows for the periods then ended subject, in the case of the unaudited
interim financial statements, to normal year-end adjustments and any other adjustments described in such financial statements.
The Company has not had any material disagreement with any of its auditors regarding accounting matters or policies during any
of its past three full years or during the current fiscal year-to-date which disagreements would require disclosure to the Company’s
Board of Directors. The books and records of the Company have been, and are being maintained in all material respects in accordance
with applicable legal and accounting requirements and the consolidated financial statements contained in the Company SEC Reports
are consistent with such books and records.

 

(b)
The Company has established and maintains, adheres to and enforces a system of internal accounting and disclosure controls which
are effective in providing assurance regarding the reliability of financial reporting and the preparation of financial statements
in accordance with GAAP (including the consolidated financial statements contained in the Company SEC Reports), including policies
and procedures that (i) require the maintenance of records that in reasonable detail accurately and fairly reflect in all material
respects the transactions and dispositions of the assets of the Company, (ii) provide assurance that transactions are recorded
as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the
Company and its subsidiaries are being made only in accordance with appropriate authorizations of management and the Board of
Directors of the Company and (iii) provide assurance regarding prevention or timely detection of unauthorized acquisition, use
or disposition of the material assets of the Company.

 

5.15.Legal
Proceedings. There are no actions, suits, proceedings, arbitrations or investigations pending or, to the Company’s Knowledge,
threatened against the Company that would be required to be disclosed on a Form 10-K or Form 10-Q pursuant to Item 103 of Regulation
S-K of the Exchange Act that are not so disclosed.

6.Representations,
Warranties and Covenants of the Purchaser.The Purchaser represents and warrants to the Company as follows:

 

6.1.Authorization.
The Purchaser is duly organized, validly existing and in good standing in the jurisdiction of its organization and has all requisite
legal and corporate or other power and capacity and has taken all requisite corporate or other action to execute and deliver the
Agreement, to purchase the Shares to be purchased by it and to carry out and perform all of its obligations under the Agreement.
This Agreement has been duly authorized, executed and delivered and constitutes the legal, valid and binding obligation of the
Purchaser, enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, moratorium,
reorganization or other similar laws affecting the enforcement of creditors’ rights generally and as to limitations on the
enforcement of the remedy of specific performance and other equitable remedies. The person signing on behalf of the Purchaser
has the authority to execute this Agreement on behalf of the Purchaser.

 

6.2.Investor
Status. The Purchaser is an “accredited investor” as defined in Rule 501 of Regulation D promulgated under the
Securities Act. The Purchaser acknowledges receiving and reviewing the documents, including the documents filed with the SEC included
as exhibits thereto. The Purchaser is aware of the Company’s business affairs and financial condition and has had access
to and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares.
The Purchaser has such business and financial experience as is required to give it the capacity to utilize the information received,
to evaluate the risks involved in purchasing the Shares, to make an informed decision about purchasing the Shares and to protect
its own interests in connection with the purchase of the Shares and is able to bear the risks of an investment in the Shares.
The Purchaser is not itself a “broker” or a “dealer” as defined in the Exchange Act and is not an “affiliate”
of the Company as defined in Rule 405 promulgated under the Securities Act.

 

6.3.Investment
Intent. The Purchaser is purchasing the Shares for its own account as principal, for investment purposes only and not with
a present view to or for resale, distribution or fractionalization thereof, in whole or in part, within the meaning of the Securities
Act. The Purchaser understands that its acquisition of the Shares has not been registered under the Securities Act or registered
or qualified under any state securities or “blue sky” laws in reliance on specific exemptions therefrom, which exemptions
may depend upon, among other things, the bona fide nature of the Purchaser’s investment intent as expressed herein. The
Purchaser has, in connection with its decision to purchase the number of Shares set forth in this Agreement, relied solely upon
the representations and warranties of the Company contained herein. The Purchaser will not, directly or indirectly, offer, sell,
pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any
of the Shares, except in compliance with the Securities Act and the rules and regulations promulgated thereunder and under this
Agreement.

 

    	 	9	 

     

    

 

6.4.Registration
or Exemption Requirements. The Purchaser further acknowledges and understands that the Shares may not be resold or otherwise
transferred except in a transaction registered under the Securities Act or unless an exemption from such registration is available.
The Purchaser is able to bear the economic risk of holding the Shares for an indefinite period of time and can afford a complete
loss of its investment. The Purchaser understands that until the Shares have been registered for resale by the Company in compliance
with applicable securities laws, the certificates evidencing the Shares will be imprinted with a legend pursuant to Section 6.5
or otherwise that prohibits the transfer of the Shares, unless (i) such transaction is registered or such registration is not
required or (ii) if the transfer is pursuant to an exemption from registration, an opinion of counsel reasonably satisfactory
to the Company is obtained to the effect that the transaction is not required to be registered or is so exempt.

 

6.5.Legend.
Until and unless the Shares are registered under the Securities Act and any applicable state securities or “blue sky”
laws and regulations, and as permitted by law, each certificate representing the Shares shall bear substantially the following
legend as applicable (in addition to any legends required under applicable state securities or “blue sky” laws):

 

THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE SECURITIES OR BLUE SKY LAWS OF
ANY STATE. SUCH SECURITIES MAY NOT BE SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED WITHOUT SUCH REGISTRATION, EXCEPT UPON
DELIVERY TO THE COMPANY OF SUCH EVIDENCE AS MAY BE SATISFACTORY TO COUNSEL FOR THE COMPANY TO THE EFFECT THAT ANY SUCH TRANSFER
SHALL NOT BE IN VIOLATION OF THE SECURITIES ACT OF 1933 OR APPLICABLE STATE SECURITIES OR BLUE SKY LAWS OR ANY RULE OR REGULATION
PROMULGATED THEREUNDER.

 

6.6.No
Legal, Tax or Investment Advice. The Purchaser understands that nothing in this Agreement or any other materials presented
to the Purchaser in connection with the purchase and sale of the Shares constitutes legal, tax or investment advice. The Purchaser
has consulted, at its own expense, such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary
or appropriate in connection with its purchase of the Shares.

 

6.7.Compliance
with Other Instruments. The execution and delivery of this Agreement, the purchase of the Shares and the performance by the
Purchaser of all other obligations of the Purchaser contemplated hereby will not (i) violate any law, rule, regulation, judgment,
order or decree applicable to the Purchaser or (ii) require Purchaser to obtain any consent, approval, authorization or order
of, or filing with, any court or governmental agency or body. The Purchaser is not subject to any restriction which would prohibit
it from entering into or performing its obligations under this Agreement, except for such restrictions which would not, individually
or in the aggregate, have a material adverse effect on the ability of the Purchaser to perform its obligations under this Agreement.

7.Rule
144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC that may at any time
permit the sale of the Shares to the public without registration, the Company agrees to:

 

(a)make
and keep “Current Public Information” available, as such term defined in Rule 144 under the Securities Act
(“Rule 144”);

 

(b)use
commercially reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company
under the Securities Act and the Exchange Act; and

 

(c)furnish
to the Purchaser promptly upon request a written statement by the Company as to its compliance with the reporting requirements
of such Rule 144 and of the Securities Act and the Exchange Act, a copy of the most recent annual or quarterly report of the Company,

8.Registration
Rights.

 

8.1.Resale
Registration Request.

 

(a)The
Purchaser shall have the right by delivering a notice to the Company (a “Demand Notice”) to require the Company to
file a registration statement covering the resale of the Shares sold at the Closing (the “Registrable Shares”)
with the SEC on a registration statement in accordance with the provisions of the Securities Act (a “Demand Registration”).
The Demand Notice shall specify the number of Registrable Shares to be registered and the intended methods of disposition thereof.
Following receipt of a Demand Notice, the Company shall use commercially reasonable efforts to effect such registration by filing
a registration statement (the “Initial Registration Statement”) within 30 days thereafter, to the extent necessary
to permit the disposition (in accordance with the intended methods thereof as specified in the Demand Notice) of the Registrable
Shares so to be registered. The Company shall use commercially reasonable efforts to have the registration statement for any such
Demand Registration declared effective by the SEC as soon as practicable but in no event later than 60 days thereafter (or 120
days, in the case that the Company is notified orally or in writing, whichever is earlier, by the SEC that such registration statement
will be subject to full review by the SEC) (the “Effectiveness Date”). The offering of the Registrable Shares
pursuant to a registration statement shall be made on a delayed or continuous basis pursuant to Rule 415, or if Rule 415 is not
available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable Shares as the
Purchaser has specified in the Demand Notice. The Initial Registration Statement shall be on Form S-3 (except if the Company is
ineligible to register for resale the Registrable Shares on Form S-3, in which case such registration shall be on another appropriate
form). The Purchaser and its counsel shall have a reasonable opportunity to review and comment upon the Initial Registration Statement
and any amendment or supplement to such Initial Registration Statement and any related prospectus prior to its filing with the
SEC, and the Company shall give due consideration to all such reasonable comments. The Purchaser shall furnish all information
reasonably requested by the Company for inclusion therein.

 

    	 	11	 

     

    

 

(b)No
Demand Registration shall be deemed to have occurred for purposes of this Section 8.1 if the Initial Registration Statement (A)
does not become effective, (B) is not maintained effective for the period required pursuant to this Section 8, or (C) the offering
of the Registrable Shares pursuant to such registration statement is or becomes subject to a stop order, injunction or similar
order or requirement of the SEC during such period, in which case the holders of Registrable Shares shall be entitled to an additional
Demand Registration, as the case may be, in lieu thereof.

 

(c)In
the event the SEC informs the Company that all of the Registrable Shares cannot, as a result of the application of Rule 415, be
registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform the
Purchaser thereof, (ii) use commercially reasonable efforts to file amendments to the Initial Registration Statement as required
by the SEC and/or (iii) withdraw the Initial Registration Statement and file a new registration statement (a “New Registration
Statement”), in either case covering the maximum number of Registrable Shares permitted to be registered by the SEC,
on Form S-3 or, if the Company is ineligible to register for resale the Registrable Shares on Form S-3, such other form available
to register for resale the Registrable Shares as a secondary offering; provided, however, that prior to filing such amendment
or New Registration Statement, the Company shall be obligated to use commercially reasonable efforts to advocate with the SEC
for the registration of all of the Registrable Shares. In the event the Company amends the Initial Registration Statement or files
a New Registration Statement, as the case may be, under clauses (ii) or (iii) above, the Company will use commercially reasonable
efforts to file with the SEC, as promptly as allowed by the SEC, one or more registration statements on Form S-3 or, if the Company
is ineligible to register for resale the Registrable Shares on Form S-3, such other form available to register for resale those
Registrable Shares that were not registered for resale on the Initial Registration Statement, as amended or the New Registration
Statement (the “Remainder Registration Statements”).

 

Notwithstanding
any other provision of this Agreement and subject to the payment of damages in Section 8.3., if the SEC limits the number of Registrable
Shares permitted to be registered on a particular registration statement (and notwithstanding that the Company used diligent efforts
to advocate with the SEC for the registration of all or a greater number of Registrable Shares), any required cutback of Registrable
Shares shall be applied pro rata among the holders of Registrable Shares in accordance with the number of such Registrable Shares
sought to be included in such registration statement by reference to the aggregate amount of all Registrable Shares.

 

    	 	12	 

     

    

 

(d)The
Company shall be required to maintain the effectiveness of the Initial Registration Statement until the earlier of the time (A)
at which all Registrable Shares included in such registration statement may be sold without restriction (including without limitation,
with respect to “affiliate” status) and without the need for current public information required by Rule 144, as applicable
or (B) that all Registrable Shares included in such registration statement actually have been sold. In the event that all Registrable
Shares may be sold without restriction under Rule 144 as described above, and as a pre-condition to termination of the Company’s
obligation to maintain a registration statement for such securities, the Company shall have (a) instructed its transfer agent
to remove all restrictive legend or electronic equivalent reflected on the Registrable Shares and (b) provided to the holders
of the Registrable Shares written acknowledgement from the Company’s transfer agent that (i) no conditions exist to the
removal of all restrictive legends or electronic equivalent and (ii) it will remove the restrictive legends immediately upon request
of the holders of Registrable Shares and, if certificated, presentation of the certificates representing the Registrable Shares.

 

(e)The
Company shall not be required to effect a Demand Registration after such time as (A) all of the Registrable Shares may be sold
without restriction under Rule 144 (including without limitation, with respect to “affiliate” status) and without
the need for current public information required by Rule 144, as applicable, and (B) the Company has provided to the holders of
the Registrable Shares written acknowledgement from the Company’s transfer agent that (i) no conditions exist to the removal
of all restrictive legends or electronic equivalent and (ii) it will remove the restrictive legends or electronic equivalent reflected
on the Registrable Shares immediately upon request of the holders of Registrable Shares and, if certificated, presentation of
the certificates representing the Registrable Shares.

 

8.2.All
expenses incurred by the Company in complying with Section 8.1. hereof, including, without limitation, all registration, qualification
and filing gees, printing expenses, escrow fees, fees and expenses of counsel for the Company, blue sky fees and expenses and
the expense of any special audits incident to or required by any such registration (but excluding the fees of legal counsel for
any Purchaser or holder of Registrable Shares) shall be borne by the Company. All selling commissions applicable to the sale of
Registrable Shares and all fees and expenses of legal counsel for any Purchaser or holder of Registrable Shares related to the
registration and sale of the Registrable Shares shall be borne by the Purchaser or holder of Registrable Shares incurring such
commissions, fees or expenses.

 

8.3.The
Company further agrees that, in the event that the Initial Registration Statement or the New Registration Statement, as applicable,
has not been declared effective by the SEC by the Effectiveness Date (a “Registration Default”), for all or
part of any thirty-day (30) period (a “Penalty Period”) during which the Registration Default remains uncured
(which initial thirty-day period shall commence on the fifth (5th) business day after the date of such Registration
Default if such Registration Default has not been cured by such date), the Company shall pay to the Purchaser one percent (1%)
of the Purchaser’s aggregate purchase price of its Shares for each Penalty Period during which the Registration Default
remains uncured; provided, however, that if the Purchaser fails to provide the Company with any information that is required to
be provided in such registration statement with respect to the Purchaser as set forth herein, then the commencement of the Penalty
Period described above shall be extended until two (2) business days following the date of receipt by the Company of such required
information; and provided, further, that in no event shall the Company be required hereunder to pay to the Purchaser pursuant
to this Agreement more than 1% of the Purchaser’s aggregate purchase price of its securities in any Penalty Period and in
no event shall the Company be required hereunder to pay to the Purchaser pursuant to this Agreement an aggregate amount that exceeds
6.0% of the aggregate Sale Proceeds paid by the Purchaser for the Purchaser’s Shares. The Company shall deliver said cash
payment to the Purchaser by the fifth (5th) business day after the end of such Penalty Period. If the Company fails
to pay said cash payment to the Purchaser in full by the fifth (5th) business day after the end of such Penalty Period,
the Company will pay interest thereon at a rate of 10% per annum (or such lesser maximum amount that is permitted to be paid by
applicable law) to the Purchaser, accruing daily from the date such liquidated damages are due until such amounts, plus all such
interest thereon, are paid in full.

 

    	 	13	 

     

    

 

8.4.In
the case of the registration, qualification, exemption or compliance effected by the Company pursuant to this Agreement, the Company
shall, upon reasonable request, inform the Purchaser as to the status of such registration, qualification, exemption and compliance.
At its expense the Company shall:

 

(a)except
for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a registration statement,
use its commercially reasonable efforts to keep such registration, and any qualification, exemption or compliance under state
securities laws which the Company determines to obtain, continuously effective with respect to the Purchaser, and to keep the
applicable registration statement free of any material misstatements or omissions, until the later of (a) three (3) years from
the Closing Date and (b) the date by which all the Shares may be sold without restriction under Rule 144, including, without limitation,
any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144. The period of time during which
the Company is required hereunder to keep a registration statement effective is referred to herein as the “Registration
Period.”

 

(b)advise
the Purchaser within five (5) business days:

 

(i)when
a registration statement or any amendment thereto has been filed with the SEC and when such registration statement or any post-effective
amendment thereto has become effective;

 

(ii)of
any request by the SEC for amendments or supplements to any registration statement or the prospectus included therein or for additional
information;

 

(iii)of
the issuance by the SEC of any stop order suspending the effectiveness of any registration statement or the initiation of any
proceedings for such purpose;

 

(iv)of
the receipt by the Company of any notification with respect to the suspension of the qualification of the Registrable Shares included
therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

 

(v)subject
to the provisions this Agreement, of the occurrence of any event that requires the making of any changes in any registration statement
or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required
to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances
under which they were made) not misleading;

 

    	 	14	 

     

    

 

(c)use
its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any registration statement
as soon as reasonably practicable;

 

(d)if
the Purchaser so requests in writing, promptly furnish to the Purchaser, without charge, at least one copy of each registration
statement and each post-effective amendment thereto, including financial statements and schedules, and, if explicitly requested,
all exhibits in the form filed with the SEC;

 

(e)during
the Registration Period, promptly deliver to the Purchaser, without charge, as many copies of each prospectus included in a registration
statement and any amendment or supplement thereto as the Purchaser may reasonably request in writing; and the Company consents
to the use, consistent with the provisions hereof, of the prospectus or any amendment or supplement thereto by the Purchaser of
Registrable Shares in connection with the offering and sale of the Registrable Shares covered by a prospectus or any amendment
or supplement thereto;

 

(f)during

(or similar form), (B) its definitive proxy statement with respect to its annual meeting of stockholders, (C) each of its quarterly
reports to its stockholders, and, if not included in substance in its quarterly reports to stockholders, its quarterly report
on Form 10-Q (or similar form), and (D) a copy of each full registration statement (the foregoing, in each case, excluding exhibits);
and (ii) if explicitly requested, all exhibits excluded by the parenthetical to the immediately preceding clause (D);

 

(g)prior
to any public offering of Registrable Shares pursuant to any registration statement, promptly take such actions as may be necessary
to register or qualify or obtain an exemption for offer and sale under the securities or blue sky laws of such United States jurisdictions
as the Purchaser reasonably request in writing, provided that the Company shall not for any such purpose be required to qualify
generally to transact business as a foreign corporation in any jurisdiction where it is not so qualified or to consent to general
service of process in any such jurisdiction, and do any and all other acts or things reasonably necessary or advisable to enable
the offer and sale in such jurisdictions of the Registrable Shares covered by any such registration statement;

 

(h)upon
the occurrence of any event contemplated by Section 8.4.(b)(v) above, except for such times as the Company is permitted hereunder
to suspend the use of a prospectus forming part of a registration statement, the Company shall use its commercially reasonable
efforts to prepare a post-effective amendment to such registration statement or a supplement to the related prospectus, or file
any other required document so that, as thereafter delivered to purchasers of the Registrable Shares included therein, such prospectus

(k)use
its commercially reasonable efforts to take all other steps necessary to effect the registration of the Registrable Shares contemplated
hereby and to enable the Purchaser to sell Registrable Shares under Rule 144.

 

8.5.The
Purchaser shall have no right to take any action to restrain, enjoin or otherwise delay any registration pursuant to Section 8.1.
hereof as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement.

 

8.6.
Indemnification.

 

(a)To
the extent permitted by law, the Company shall indemnify the Purchaser and each person controlling the Purchaser within the meaning
of Section 15 of the Securities Act, with respect to which any registration that has been effected pursuant to this Agreement,
against all claims, losses, damages and liabilities (or action in respect thereof), including any of the foregoing incurred in
settlement of any litigation, commenced or threatened (subject to subsection (c) below), arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus, any amendment
or supplement thereof, or other document incident to any such registration, qualification or compliance or based on any omission
(or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein
not misleading, in light of the circumstances in which they were made, or any violation by the Company of any rule or regulation
promulgated by the Securities Act applicable to the Company and relating to any action or inaction required of the Company in
connection with any such registration, qualification or compliance, and will reimburse the Purchaser and each person controlling
the Purchaser, for reasonable legal and other out-of-pocket expenses reasonably incurred in connection with investigating or defending
any such claim, loss, damage, liability or action as incurred; provided that the Company will not be liable in any such case to
the extent that any untrue statement or omission or allegation thereof is made in reliance upon and in conformity with written
information furnished to the Company by or on behalf of the Purchaser for use in preparation of any registration statement, prospectus,
amendment or supplement; provided however, that the Company will not be liable in any such case where the claim, loss, damage
or liability arises out of or is related to the failure of the Purchaser to comply with the covenants and agreements contained
in this Agreement respecting sales of Registrable Shares, and except that the foregoing indemnity agreement is subject to the
condition that, insofar as it relates to any such untrue statement or alleged untrue statement or omission or alleged omission
made in any preliminary prospectus but eliminated or remedied in the amended prospectus on file with the SEC at the time any registration
statement becomes effective or in an amended prospectus filed with the SEC pursuant to Rule 424(b) which meets the requirements
of Section 10(a) of the Securities Act (each, a “Final Prospectus”), such indemnity shall not inure to the
benefit of the Purchaser or any such controlling person, if a copy of a Final Prospectus furnished by the Company to the Purchaser
for delivery was not furnished to the person or entity asserting the loss, liability, claim or damage at or prior to the time
such furnishing is required by the Securities Act and a Final Prospectus would have cured the defect giving rise to such loss,
liability, claim or damage.

 

    	 	16	 

     

    

 

(b)The
Purchaser will severally, and not jointly, indemnify the Company, each of its directors and officers, and each person who controls
the Company within the meaning of Section 15 of the Securities Act, against all claims, losses, damages and liabilities (or actions
in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject
to subsection (c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained
in any registration statement, prospectus, or any amendment or supplement thereof, incident to any such registration, or based
on any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, in light of the circumstances in which they were made, and will reimburse the Company, such
directors and officers, and each person controlling the Company for reasonable legal and any other expenses reasonably incurred
in connection with investigating or defending any such claim, loss, damage, liability or action as incurred, in each case to the
extent, but only to the extent, that such untrue statement or omission or allegation thereof is made in reliance upon and in conformity
with written information furnished to the Company by or on behalf of the Purchaser for use in preparation of any registration
statement, prospectus, amendment or supplement; provided that the indemnity shall not apply to the extent that such claim, loss,
damage or liability results from the fact that a current copy of a prospectus was not made available to the person or entity asserting
the loss, liability, claim or damage at or prior to the time such furnishing is required by the Securities Act and a Final Prospectus
would have cured the defect giving rise to such loss, claim, damage or liability. Notwithstanding the foregoing, the Purchaser’s
aggregate liability pursuant to this subsection (ii) and subsection (iv) shall be limited to the net amount received by the Purchaser
from the sale of the Registrable Shares.

 

(c)Each
party entitled to indemnification under this Section 8.6. (the “Indemnified Party”) shall give notice to the
party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at its expense)
to assume the defense of any such claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party,
who shall conduct the defense of such claim or litigation, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld, conditioned or delayed), and the Indemnified Party may participate in such defense at such Indemnified
Party’s expense, and provided further that the failure of any Indemnified Party to give notice as provided herein shall
not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the
Indemnifying Party in defending such claim or litigation. An Indemnifying Party shall not be liable for any settlement of an action
or claim effected without its written consent (which consent will not be unreasonably withheld, conditioned or delayed). No Indemnifying
Party, in its defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry
of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant
or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation.

(d)If
the indemnification provided for in this Section 8.6. is held by a court of competent jurisdiction to be unavailable to an Indemnified
Party with respect to any loss, liability, claim, damage or expense referred to therein, then the Indemnifying Party, in lieu
of indemnifying such Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as
a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault
of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions
which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative
fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied
by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information
and opportunity to correct or prevent such statement or omission.

 

8.7.Purchaser
Obligations.

 

(a)The
Purchaser agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of
a supplement or amendment to a prospectus relating to Registrable Shares so that, as thereafter delivered to the Purchaser, such
prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein not misleading, the Purchaser will forthwith discontinue disposition of Registrable
Shares pursuant to a registration statement and prospectus contemplated by Section 8.1. until its receipt of copies of the supplemented
or amended prospectus from the Company and, if so directed by the Company, the Purchaser shall deliver to the Company all copies,
other than permanent file copies then in the Purchaser’s possession, of the prospectus covering such Registrable Shares
current at the time of receipt of such notice.

 

(b)
The Purchaser shall suspend, upon request of the Company, any disposition of Registrable Shares pursuant to any registration statement
and prospectus contemplated by Section 8.1. during the occurrence or existence of any pending corporate development with respect
to the Company that the Board of Directors of the Company believes in good faith may be material and that, in the determination
of the Board of Directors of the Company, makes it not in the best interest of the Company to allow continued availability of
a registration statement or prospectus.

 

    	 	18	 

     

    

 

(c)
As a condition to the inclusion of its Registrable Shares, the Purchaser shall furnish to the Company such information regarding
the Purchaser and the distribution proposed by the Purchaser as the Company may reasonably request in writing, including completing
a registration statement questionnaire in the form provided by the Company, or as shall be required in connection with any registration
referred to in this Section 8.

 

(d)
The Purchaser hereby covenants with the Company (i) not to make any sale of the Registrable Shares without effectively causing
the prospectus delivery requirements under the Securities Act to be satisfied, and (ii) if such Registrable Shares are to be sold
by any method or in any transaction other than on a national securities exchange or in the over-the-counter market, in privately
negotiated transactions, or in a combination of such methods, to notify the Company at least three (3) business days prior to
the date on which the Purchaser first offers to sell any such Registrable Shares.

 

(e)The
Purchaser agrees not to take any action with respect to any distribution deemed to be made pursuant to a registration statement
which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law.

 

(f)At
the end of the Registration Period the Purchaser shall discontinue sales of shares pursuant to any registration statement upon
receipt of notice from the Company of its intention to remove from registration the shares covered by any such registration statement
which remain unsold, and the Purchaser shall notify the Company of the number of shares registered which remain unsold immediately
upon receipt of such notice from the Company.

 

8.8.The
rights to cause the Company to register Registrable Shares granted to the Purchaser by the Company under Section 8.1. may be assigned
by the Purchaser in connection with a transfer by the Purchaser of all or a portion of its Registrable Shares, provided, however,
that such transfer must be made at least ten (10) days prior to the Filing Date and that (i) such transfer may otherwise be effected
in accordance with applicable securities laws; (ii) the Purchaser gives prior written notice to the Company at least ten (10)
days prior to the Filing Date; and (iii) such transferee agrees to comply with the terms and provisions of this Agreement, and
such transfer is otherwise in compliance with this Agreement. Except as specifically permitted by this Section 8.8., the rights
of the Purchaser with respect to Registrable Shares as set out herein shall not be transferable to any other Person, and any attempted
transfer shall cause all rights of the Purchaser therein to be forfeited.

 

8.9.The
rights of the Purchaser under any provision of this Article VIII may be waived (either generally or in a particular instance,
either retroactively or prospectively and either for a specified period of time or indefinitely) or amended by an instrument in
writing signed by the Purchaser.

12.3.Binding
Effect; Assignment. This Agreement shall be binding upon and inure to the benefit of the Company and the Purchaser and their
