 Exhibit 10.4 

ADMINISTRATIVE SERVICES AGREEMENT 

THIS ADMINISTRATIVE SERVICES AGREEMENT (this “Agreement”) is made as of November 1, 2012 (the “Effective
Date”), by and between Akebia Therapeutics, Inc. (“Akebia”) and Aerpio Therapeutics, Inc. (“Aerpio”). 

WHEREAS, Akebia wishes to enter into this Agreement to obtain from Aerpio certain services on an interim basis as set forth in this
Agreement; and 
 WHEREAS, Aerpio wishes to enter into this Agreement to provide Akebia certain services on an interim basis
as set forth in this Agreement. 
 NOW, THEREFORE, in consideration of the above recitals and the mutual covenants hereinafter
set forth, and for other good and valuable consideration, the receipt and sufficiency of which the parties hereby acknowledge, Akebia and Aerpio hereby agree as follows: 

1. Definitions. As used here, each of the following capitalized terms shall have the following meanings ascribed to it: 

1.1. “Contribution Agreement” shall mean the Asset Contribution Agreement, dated as of December 22, 2011, by and
between Akebia and Aerpio, as it may be amended, restated supplemented or otherwise modified from time to time. 
 1.2. An
“Event of Default” shall occur when a party breaches any material term or condition of this Agreement and such party fails to cure such breach within ten (10) days after receiving written notice of such breach from the other
party. A breach of a material term shall mean (a) a failure to perform any of the Services in the manner set forth herein or (b) a failure to pay any undisputed amount under this Agreement. 

1.3. “Services” shall mean the services and arrangements described on Exhibit A attached hereto. 

2. Administrative Services. 
 2.1.
Services. Subject to, and in accordance with, the terms and conditions of this Agreement, Aerpio will provide the Services, or cause the Services to be provided, to Akebia at the location from which such Service is currently provided (unless
agreed to in writing by the other party, which consent shall not be unreasonably withheld or delayed), for the corresponding time period and at the corresponding fee or cost that is specified on Exhibit A opposite each Service (pro rated for
partial months, if applicable). Where an administrative plan is specified on Exhibit A for a particular Service, Aerpio shall perform its respective tasks as specified in such administrative plan. 

        2.2. Additional Services. In the event that Akebia determines that there are additional services that
Aerpio has historically provided to Akebia’s business relating to its product AKB-6548 which, for clarity, shall not include any business relating to Aerpio’s products AKB-4924, AKB-9089 and AKB-9778, (the “Akebia Business”) that
are not included in the Services, Akebia may request Aerpio to provide such services, and Aerpio and Akebia shall negotiate in 

 
good faith to add such services to the Services on the terms and conditions set forth in this Agreement. Exhibit A shall be appropriately modified to reflect such additions. For the
avoidance of doubt, in the event such additional services are requested, the cost for such services shall be consistent with the historical cost of providing such services internally. 

2.3. Service Levels. The Services shall be provided in a timely, professional and workmanlike manner and in a manner consistent and with
the same degree of care and skill, in all material respects, with the service provider’s practices with respect to the provision of the same or similar services prior to the date hereof, except to the extent otherwise specified on Exhibit
A. Each party shall undertake to provide the Services in accordance with all applicable Laws and permits applicable at the location in which the Services are rendered. 

2.4. Access. The parties acknowledge that in the course of providing certain Services, personnel of one party may need access to the
facilities and/or equipment owned or leased by the other party. Each party shall provide such personnel of the other party with such access as is reasonably required to provide such Services hereunder. 

2.5. IT Systems. Each of the parties hereby grants to the other party a non-exclusive, non-transferable license to use the
network of voice and data equipment and all hardware, software and other equipment used by such party on their own account or under any licenses (to the extent permitted under such licenses) (the “IT Systems”). Such license is
granted for the Term (as defined below) of this Agreement for the sole purpose of enabling the parties to use and obtain the benefit of the Services. 

Each of the parties reserves the right to limit, eliminate, suspend or terminate access to all or any portion of such party’s IT Systems
following notice to the other party to the extent such party determines, in its sole and absolute discretion, that the other party or any representative, agent, affiliate or employee of the other party is engaging in any activity or conduct on or in
connection with such IT Systems that presents a threat of harm, injury or damage to such party or any of its employees, agents, representatives or customers or that is beyond the scope of the purpose for which the license described in this
Section 2.5 is granted; provided, however, that prior notice shall not be required to be given if such a delay may cause irreparable damage to such party. Such party shall restore access immediately upon receipt of reasonable evidence from the
other party that any such activity or conduct has been terminated. In no event shall such party be liable to the other party or any representative, agent, affiliate or employee of the other party for any action taken to limit, eliminate, suspend or
terminate access to all or any portion of such IT Systems in accordance with the foregoing sentence. 
 3. Fees; Invoice and Payment. 

3.1. Fees. In consideration of the rendering of Services hereunder, the parties hereto agree to pay the fees and charges associated with
each Service as specified in Exhibit A (prorated for partial months, if applicable). 
         3.2. Invoice and
Payment. On a monthly basis, Aerpio shall submit an invoice to the Akebia for the corresponding fees and charges specified in Exhibit A, and, if such Exhibit A specifies that expenses are to also be charged for particular Services,
any associated expenses, 

  
 2 

 
for the Services provided in the prior calendar month. Such invoices shall be accompanied by written documentation itemized with sufficient detail to support the invoiced amounts. The invoices
shall be paid, less any amounts subject to a bona fide dispute, no later than thirty (30) days following the date the applicable invoice is received. All amounts not paid within such time period (and not subject to a bona fide dispute) shall
accrue interest at the rate of one and one-half percent (1.5%) per month (or the highest interest rate allowed by law, if lower) until such amounts are paid in full. If a party brings suit or retains an attorney to collect any monies due
hereunder, and such party is successful in such action, then it shall be entitled to recover, in addition to any other remedy, reimbursement for its actual and reasonable attorney fees, court costs and other related expenses incurred in connection
therewith from the other party. 
 3.3. Miscellaneous Third-Party Charges. To the extent one party uses the other party’s account
numbers or other arrangements, such party shall use diligent efforts to cease using such account numbers and other arrangements. In the event any goods or services ordered by or provided to one party are billed to the other party, such other party
shall submit an invoice to such party for such amount, accompanied by written documentation itemized with sufficient detail to support the invoiced amount. Such party shall pay such invoiced amount in accordance with the payment terms specified in
Section 3.2 above. 
 4. Cooperation and Assistance. 

4.1. Financial and Accounting Information. During the Term, and for seven (7) years thereafter, each party shall, upon written
request by the other party, provide to the requesting party reasonable access during normal working hours and under the supervision of the party providing such access, to such financial and accounting information of such party as is reasonably
required for the requesting party to respond to any audit (or similar action) conducted by a governmental entity, or to perform its tax filings and reports, end of the month, end of fiscal quarter and end of fiscal year financial closing process,
and to prepare the related financial statements and accounting reports, or to revise any financial statements and accounting reports for any prior periods. Prior to the provision of any such access, any outside auditor or similar person engaged by
the requesting party must agree to be bound by standard confidentiality obligations, and all information disclosed to the requesting party or its auditor or similar person in connection with such requests shall be considered confidential information
and treated as such. 
 4.2. Cooperation. The parties acknowledge and agree that the parties will act in good faith and reasonably
cooperate with one another during the Term (each at its own expense, except as otherwise specified herein or on Exhibit A). To the extent that the parties share certain Services during the Term as described on Exhibit A, the parties
shall act in a reasonable manner with respect to the sharing of such Services. However, subject to Sections 2.3 and 2.6, nothing herein shall obligate either to provide any Services involving a level of service that is greater than the level of
service historically provided with respect to such Services. 
 5. Term; Termination of Services or Agreement. 

  
 3 

 5.1. Term. The term of this Agreement shall commence on the Effective Date and, unless
earlier terminated by mutual written agreement of the parties or as otherwise provided in accordance with the terms of this Section 5, shall continue until such time as Akebia has not requested any Services of Aerpio for more than ninety
(90) days (the “Term”), provided that the Term shall not extend for more than ninety (90) days after all or substantially all the business of either party is acquired by a third party (by sale, merger, securities
acquisition or other means). The Term may be extended by the parties in writing either in whole or with respect to one or more of the Services; provided, however, that in the latter case, such extension will apply only to the Services for which the
Agreement was extended. The parties will be deemed to have extended this Agreement with respect to a specific Service if additional Services are added to Exhibit A pursuant to Section 2.2 that are contemplated to be provided beyond the
Term. Each Service specified herein may be terminated earlier (on a Service by Service basis) by mutual agreement of the parties in accordance with the provisions of this Section 5. Upon any termination of a Service described herein, Akebia
shall no longer be obligated to pay Aerpio the fees attributable to a canceled Service following the effective termination date of such Service(s); provided that Akebia fully pays any and all fees, charges or other similar payment due and
accrued in connection with Service(s) provided up to and including the effective termination date. If an element of a Service is terminated pursuant to this Section 5.1, the parties shall negotiate in good faith to determine a reduction in the
fees reflecting such terminated element. 
 5.2. Termination for Breach. Each party shall have the right to terminate this Agreement,
in part (by terminating one or more Services) or in its entirety, upon an Event of Default by the other party. 
 5.3. Survival. The
provisions of Sections 2.3, 3, 4, 5, 6, 7, 8, 9 and 11 shall survive any termination or the expiration of this Agreement. 
 6. Intellectual
Property. 
         6.1. This Agreement and the performance of this Agreement will not affect the ownership of
any intellectual property rights allocated in the Contribution Agreement or the Ancillary Agreements (as defined in the Contribution Agreement). Subject to the foregoing sentence, all works of authorship, designs, inventions, improvements,
technology, developments, discoveries and trade secrets conceived, made, or discovered by Aerpio during the period when the Services are provided, whether solely or in collaboration with others, that relate solely to the Akebia Business
(collectively, “Inventions” and each individually, an “Invention”) will be the sole property of Akebia. In addition, Inventions that constitute copyrightable subject matter will be considered “works for hire” as that
term is defined in the United States Copyright Act. To the extent that ownership of the Inventions does not by operation of law or by operation of agreement automatically vest in Akebia, Aerpio will assign (or cause to be assigned) and does hereby
assign fully to Akebia, all right, title and interest in and to the Inventions, including any and all related intellectual property rights residing therein. If in the course of performing the Services, Aerpio incorporates into any Invention any
other work of authorship, invention, improvement, or proprietary information, or other materials owned by Aerpio or in which Aerpio has an interest, Aerpio will grant and does now grant to Akebia a nonexclusive, royalty-free, perpetual, irrevocable,
worldwide license to reproduce, manufacture, modify, create derivative 

  
 4 

 
works thereof, distribute, use, import; and otherwise exploit the material as part of or in connection with the Invention. If Aerpio’s unavailability or any other factor prevents Akebia from
pursuing or applying for any United States or foreign registrations or applications covering the Inventions and any related intellectual property rights residing therein assigned to Akebia, then Aerpio irrevocably designates and appoints Akebia, as
Aerpio’s agent and attorney in fact. Accordingly, Akebia may act for and in Aerpio’s behalf and stead to execute and file any applications and to do all other lawfully permitted acts to further the prosecution and issuance of the
registrations and applications with the same legal force and effect as if executed by Aerpio. 
 7. Relationship between the Parties. The
relationship between the parties established under this Agreement is that of independent contractors and neither party is, or should be considered to be, an employee, agent, partner, or joint venture of the other. Except as set forth in any other
agreement entered into on the date hereof in connection with the Contribution Agreement, each party shall be solely responsible for any employment-related taxes, insurance premiums or other employment benefits with respect to its personnel who
perform Services under this Agreement. 
 8. Limitation of Liability; Waivers; Indemnification. 

8.1. Aerpio hereby irrevocably waives and agrees not to assert, by way of motion, defense or otherwise, any non-competition and
non-solicitation claims against any individual set forth on Exhibit A as of the date hereof that later becomes an employee of Akebia; provided, however, that such waiver does not compromise any rights Aerpio may have against such individual
with respect to confidentiality and assignment of intellectual property rights. 
 8.2. Aerpio hereby acknowledges that certain Aerpio
employees have direct agreements with Akebia, and Aerpio hereby waives any conflict that may be created by such direct agreements with any obligation such employee may have to Aerpio (including, without limitation, from any agreement between such
employee and Aerpio, including, for example, any agreement concerning any confidentiality, non-compete, non-solicit or assignment obligations), so that this Agreement and those direct agreements take priority over any such obligations. 

8.3. EXCEPT WITH RESPECT TO AMOUNTS PAYABLE ARISING OUT OF CLAIMS RELATING TO BREACH OF CONFIDENTIALITY OR BASED UPON WILLFUL, MALICIOUS,
ILLEGAL OR GROSSLY NEGLIGENT CONDUCT OF THE LIABLE PARTY, IN NO EVENT WILL EITHER PARTY BE LIABLE FOR ANY INCIDENTAL, INDIRECT, SPECIAL OR CONSEQUENTIAL DAMAGES INCLUDING, WITHOUT LIMITATION, LOSS OF USE, REVENUES, PROFITS OR SAVINGS, EVEN IF SUCH
PARTY KNEW OR SHOULD HAVE KNOWN OF THE POSSIBILITY OF SUCH DAMAGES. 

  
 5 

 9. Proprietary Information. Each party will maintain as confidential all non-public
information relating to the other party, its affiliates or any third party that is obtained by a party in connection with the performance of the Services. Said information will only be used for a permitted purpose hereunder. Each party will use
reasonable efforts to safeguard the confidentiality of such proprietary information furnished by the disclosing party. The following shall not be considered proprietary information: (a) information that is now in the public domain or
subsequently enters the public domain through no fault of the receiving party, (b) information that is presently known or becomes known to the receiving party from its own independent sources, (c) information that the receiving party
receives from any third party not under any obligation to keep such information confidential, and (d) information that is required to be disclosed by law. 

10. Project Managers: Escalation. Akebia and Aerpio will each assign one person to act as that party’s project manager for the
activities under this Agreement. Such project managers shall (i) represent and act for their respective party for matters hereunder, (ii) receive and provide all communications between the parties relating to operational matters arising
hereunder, and (iii) meet and/or confer on a regular basis (at mutually agreed times and locations) to review the activities under this Agreement and to discuss the status and progress of such activities. All disputes or issues arising
hereunder shall be referred to the project managers for resolution. In the event any such dispute or issue is not resolved in a timely manner, such matter shall be referred to senior management representatives, with appropriate decision making
authority, from each party for prompt resolution of the matter. 
 11. Miscellaneous. 

11.1. Disputes. In the case of any disputes under this Agreement, the parties shall first attempt in good faith to resolve their dispute
informally using the procedures described in Section 10. In the event the parties are unable to resolve such dispute using such procedures, any party may avail itself of any remedies available to it, whether at law or in equity, including
recourse to any appropriate state or federal court in the state. 
 11.2. Further Assurances. Each party shall execute such documents
and other papers and take such further actions as may be reasonably required or desirable to carry out the provisions hereof and the transactions contemplated hereby. 

11.3. Headings. Titles and headings to sections and subsections herein are inserted for convenience of reference only and are not
intended to be a part of or to affect the meaning or interpretation of this Agreement. 
 11.4. Expenses. Except as otherwise provided
herein, each party will pay all costs and expenses incident to its negotiation and preparation of this Agreement and to its performance and compliance with all agreements and conditions contained herein on its part to be performed or complied with.

         11.5. Assignment. Neither party shall, without the prior written consent of the other party, assign
or otherwise transfer, by operation of law or otherwise, this Agreement or the rights and obligations hereunder, and any attempt to assign or otherwise transfer this Agreement or the 

  
 6 

 
rights or obligations hereunder other than in accordance with the provisions of this section shall be void and of no effect, provided that, without such consent, (i) either party may assign
this Agreement to an affiliate of such party, and (ii) either party may sell all or substantially all the business of such party (by sale, merger, securities acquisition or other means) to a third party and may elect to retain this Agreement or
assign this Agreement to the acquirer of such business. Subject to the foregoing, this Agreement will bind and inure to the benefit of the parties, their respective successors and permitted assigns. 

11.6. Notices. All notices, demands or consents required or permitted under this Agreement shall be given in the manner specified in
Section 6.1 of the Contribution Agreement. 
 11.7. Entire Agreement. This Agreement (including any exhibits) and that
certain Amended and Restated Services Agreement, by and between Akebia and Aerpio, dated as of August 27, 2012 (the “Aerpio Services Agreement”), constitute the entire agreement and understanding between the parties,
superseding and replacing any and all prior agreements, communications, and understandings (both written and oral) regarding the subject matter hereof. This Agreement will be understood and interpreted in connection with the Aerpio Services
Agreement, and nothing in this Agreement will be deemed to modify, extend or limit the obligations and requirements under the Aerpio Services Agreement. 

11.8. Amendment; Waiver. No term or provision of this Agreement may be amended or supplemented except by a writing signed by each of
Akebia and Aerpio clearly stating the parties’ intention to amend or supplement this Agreement. No term or provision of this Agreement may be waived other than by a writing signed by the party to be bound by such waiver. No waiver by a party of
any breach of this Agreement will be deemed to constitute a waiver of any other breach or any succeeding breach. At either party’s request, the other party will consider in good faith and act upon those reasonable requests made by such first
party to amend the terms of this Agreement, or any other agreements between the parties or involving the transfer of assets between the parties, to facilitate a licensing transaction, collaboration or sale of all or substantially all of the business
of such first party (by sale, merger, securities acquisition or other means) with a third party. 
 11.9. No Third Party
Beneficiaries. Nothing expressed or implied in this Agreement is intended, or shall be construed, to confer upon or to give any person, firm or corporation, other than the parties hereto, any rights or remedies under or by reason of this
Agreement. 
 11.10. Execution in Counterparts. For the convenience of the parties, this Agreement may be executed in counterparts,
each of which shall be deemed an original but all of which together shall constitute one and the same instrument. The parties agree that the delivery of this Agreement may be effected by means of an exchange by facsimile, PDF or other electronic
methods. 
 11.11. Force Majeure. Except with respect to payment obligations, no party hereto will be deemed in default if its
performance or obligations hereunder are delayed or become impractical by reason of any act of God, war, fire, earthquake, labor dispute, civil commotion, epidemic, act of government or governmental agency or officers, or any other cause beyond such
party’s control; provided that the delayed party promptly notifies the other party of such force majeure event and uses all commercially reasonable efforts to resume performance as soon as possible. 

  
 7 

 11.12. Governing Law. This Agreement shall be governed by and construed in accordance with
the laws of the State of Delaware, without regard to its conflict of laws provisions. 
 11.13. Severability. If any provision of this
Agreement is for any reason and to any extent deemed to be invalid or unenforceable, then such provision shall not be voided but rather shall be enforced to the maximum extent then permissible under then applicable law and so as to reasonably effect
the intent of the parties hereto, and the remainder of this Agreement will remain in full force and effect. 
 11.14. Remedies
Non-exclusive. Except as otherwise set forth herein, any remedy provided for in this Agreement is deemed cumulative with, and not exclusive of, any other remedy provided for in this Agreement or otherwise available at law or in equity. The
exercise by a party of any remedy shall not preclude the exercise by such party of any other remedy. 
 11.15. Specific Performance.
The parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by them in accordance with the terms hereof and that each party shall be entitled to seek specific performance of the
terms hereof, in addition to any other remedy at law or equity.

 Exhibit 10.5 

AKEBIA THERAPEUTICS, INC. 

AMENDED AND RESTATED 2008 EQUITY INCENTIVE PLAN 

ARTICLE I 

ESTABLISHMENT AND TERM 

Section 1.01. Establishment; Definitions. This Plan was originally adopted by the Board effective April 4, 2008, and by the
stockholders of the Corporation effective April 4, 2008. This Plan was adopted in this amended and restated form by the Board effective July 28, 2009, and by the stockholders of the Corporation effective July 28, 2009. All capitalized
terms used herein are defined herein or in Appendix A attached hereto. 
 Section 1.02. Term. The Board may suspend or
terminate the Plan at any time. Unless sooner terminated, the Plan shall terminate on April 3, 2018, which shall be within ten (10) years from the date the Plan is adopted by the Board or approved by the stockholders of the Corporation,
whichever is earlier. No Equity Awards may be granted under the Plan while the Plan is suspended or after it is terminated. Suspension or termination of the Plan shall not impair rights and obligations under any Equity Award granted while the Plan
is in effect, except with the consent of the person to whom the Equity Award was granted. 
 ARTICLE II 

STRUCTURE AND PURPOSE 

Section 2.01. Section 2.01 Structure of Plan. The Equity Awards issued under the Plan shall be either, in the discretion of
the Board, (a) Options granted pursuant to Article VI hereof, including Incentive Stock Options and Non-statutory Stock Options, or (b) Stock bonuses or restricted Stock awards granted pursuant to Article VII hereof. All Options shall be
designated as Incentive Stock Options or Non-statutory Stock Options at the time of grant. 
 Section 2.02. Purpose. The
purpose of the Plan is to promote the interests of the Corporation by aligning the interests of selected eligible persons under the Plan with the interests of the stockholders of the Corporation and by providing to such persons an opportunity to
obtain the benefits from ownership of the Corporation’s Stock through the granting to such persons of Equity Awards. The Corporation, through the use of the Plan, seeks to attract and retain the services of Employees, Directors and Consultants,
and to provide additional incentives for such persons apart from the provisions of their employment agreements or other arrangements with the Corporation or its Affiliates. 

ARTICLE III 

ADMINISTRATION 

Section 3.01. Board; Delegation to Committee. The Board shall administer the Plan unless and until the Board delegates
administration to a Committee. The Board may delegate administration of the Plan to a Committee composed of two or more members of the Board,  

 
composed solely of Outside Directors or composed, if applicable law permits, of one or more officers of the Corporation. If administration is delegated to a Committee, the Committee shall have,
in administering the Plan, all of the powers that were possessed by the Board prior to such delegation, subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board. If
administration is delegated to a Committee, all references in this Plan to the Board shall thereafter be to the Committee. The Board may abolish the Committee at any time and revest in the Board the administration of the Plan. 

Section 3.02. Administration. The Board shall have the power, consistent with the express provisions of the Plan: 

To determine from time to time which of the eligible persons under the Plan shall be granted Equity Awards; 

To determine whether an Equity Award shall be an Incentive Stock Option, a Non-statutory Stock Option, a Stock bonus, a restricted Stock award
or a combination of the foregoing; 
 To approve forms of Equity Award Agreements for use under the Plan; 

To determine the number of shares of Stock to be covered by each Equity Award granted hereunder; 

To determine how and when each Equity Award shall be granted, the provisions of each Equity Award granted (including, but not limited to,
provisions setting forth or relating to exercise price, vesting schedule, vesting acceleration, forfeiture and rights of repurchase), and to provide for any and all other terms and conditions in an Equity Award which are not expressly prohibited by
the Plan; 
 To construe and interpret the Plan and Equity Awards granted under it, and to establish, amend and revoke rules and regulations
for the administration of such Plan and Equity Awards; 
 To correct any defect, omission or inconsistency in the Plan or in any Equity
Award Agreement, in a manner and to the extent it shall deem necessary or expedient to make the Plan fully effective; 
 To amend the Plan
or an Equity Award as provided in Article XI; and 
 Generally, to exercise such powers and to perform such acts as the Board deems
necessary or expedient to promote the best interests of the Corporation that are not in conflict with the provisions of the Plan. 
 Any determination by
the Board with respect to the matters referred to above shall be final and conclusive. 

  
 -2- 

 ARTICLE IV 

ELIGIBILITY 

Section 4.01. Persons Eligible for Equity Awards. Incentive Stock Options may be granted only to Employees who meet the definition
of “employee” under Section 3401(c) of the Code on the date of grant. Equity Awards other than Incentive Stock Options may be granted only to Employees, Directors or Consultants. The extent to which any such
person shall be entitled to be granted Equity Awards pursuant to the Plan shall be determined in the sole and absolute discretion of the Board. Eligibility to participate does not confer upon any Employee any right to be granted Equity Awards and
the acceptance of any Equity Award by an Employee is voluntary. 
 Section 4.02. Other Limitations. If any
payment or right accruing to an individual under this Plan (without the application of this Section 4.02), either alone or together with other payments or rights accruing to such individual from the Corporation or an Affiliate of the
Corporation (“TOTAL PAYMENTS”), would constitute a “parachute payment” (as defined in Section 280G of the Code), such payment or right shall be reduced to the largest amount or greatest right that will result in no
portion of the amount payable or right accruing under this Plan being subject to an excise tax under Section 4999 of the Code or being disallowed as a deduction under Section 280G of the Code, provided that the foregoing shall not apply to
the extent provided otherwise in an Equity Award Agreement or in the event the affected individual is party to an agreement with the Corporation or an Affiliate of the Corporation that explicitly provides for an alternate treatment of payments or
rights that would constitute “parachute payments.” The determination of whether any reduction in the rights or payments under this Plan is to apply shall be made by the Board in good faith after consultation with the affected
individual, and such determination shall be conclusive and binding on such affected individual. The affected individual shall cooperate in good faith with the Board in making such determination and providing the necessary information for this
purpose. The foregoing provisions of this Section 4.02 shall apply with respect to any person only if, after reduction for any applicable Federal excise tax imposed by Section 4999 of the Code and Federal income tax imposed by the Code,
the Total Payments accruing to such person would be less than the amount of the Total Payments as reduced, if applicable, under the foregoing provisions of this Section 4.02 and after reduction for any applicable Federal income tax imposed by
the Code. 
 ARTICLE V 

SHARES SUBJECT TO THE PLAN 

Section 5.01. Subject to the provisions of Article VIII relating to adjustments upon changes in Stock, no more than 12,667,667
shares of Stock may be issued pursuant to Equity Awards. The number of shares of Stock reserved for issuance under this Plan may be increased from time to time as permitted by law. If any Equity Award shall for any reason expire, be cancelled, be
forfeited or otherwise terminate, in whole or in part, without having been exercised in full, or if shares of Stock are not delivered because an Equity Award is settled in cash or because such shares of Stock are used to satisfy an applicable tax
withholding obligation, in whole or in part, or if shares of Stock which originally underlay an Equity Award are  

  
 -3- 

 
repurchased or otherwise reacquired by the Corporation, the Stock not acquired or delivered or reacquired (as the case may be) under such Equity Award by the holder thereof shall revert to and
again become available for issuance under the Plan. The Stock subject to the Plan may be unissued shares or reacquired shares, bought on the market or otherwise. 

ARTICLE VI 
 TERMS OF
OPTIONS 
 Section 6.01. Form of Option. Subject to the provisions of the Plan, each Option shall be in such form and shall
contain such terms and conditions as the Board shall determine. The provisions of separate Options need not be identical. 

Section 6.02. Term. No Option shall be exercisable after the expiration of ten (10) years from the date it was granted.

 Section 6.03. Exercise Price. The exercise price of each Incentive Stock Option shall be not less than one hundred
percent (100%) of the Fair Market Value of the Stock subject to the Option on the date the Option is granted. The exercise price of each Non-statutory Stock Option shall be the exercise price determined by the Board. Notwithstanding the
foregoing, an Option (whether an Incentive Stock Option or a Non-statutory Stock Option) may be granted with an exercise price lower than that otherwise provided in this Section 6.03 if such Option is granted pursuant to an assumption or
substitution for another option in a manner satisfying the provisions of Section 424(a) and Section 409A of the Code. 

Section 6.04. Exercise of Options. Subject to the provisions of Section 6.07, an Optionee may at any time prior to the
expiration or termination of an Option elect to purchase all or a portion of the Stock subject to such Option which such holder is then entitled to purchase by delivering to the Corporation a completed Stock Purchase Agreement specifying the number
of shares of Stock the Participant desires to purchase. An Option may be exercised for whole shares of Stock only. The Stock Purchase Agreement shall be accompanied by payment of the applicable exercise price for Stock being acquired. Subject to the
provisions of the Equity Award Agreement, the Corporation shall cause to be delivered to the holder a certificate for the shares of Stock so purchased. If the number of shares so purchased is less than the number of shares of Stock subject to the

 Section 6.07. Vesting. Subject to the provisions of the Plan, the Board, in its
discretion, shall determine at the time of grant the time when an Option vests, becomes exercisable and shall expire, and such determinations shall be set forth in the applicable Equity Award Agreement. An Option may be subject to such other terms
and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Board may deem appropriate, and the Board may provide for early exercise of unvested Options (with the Stock received therefor
being itself subject to vesting) if expressly set forth in an Equity Award Agreement. Unless otherwise approved by the Board and set forth in writing by an authorized officer of the Corporation, an Option shall cease vesting upon the Optionee’s
Termination, regardless of whether or not the Optionee was given requisite notice of Termination of such Optionee’s employment by the Corporation or by any Affiliate of the Corporation. 

Section 6.08. Termination of Employment or Relationship as a Director or Consultant. An Option will expire immediately upon the
Optionee’s Termination for Cause. Unless otherwise provided in the Equity Award Agreement relating to an Option, in the event of an Optionee’s Termination (for reasons other than Cause, the Optionee’s death or the Optionee’s
Disability), the Optionee may exercise the Option to the extent of the shares in respect of which such Option is exercisable on the date notice of Termination is given to the Optionee by the Corporation or any Affiliate of the Corporation at any
time beginning on such date and ending on the earlier of (a) the date one (1) month after such notice of Termination is delivered to the Optionee, or (b) the expiration of the term of the Option as set forth in the Equity Award
Agreement. The time period for the exercise of such Options applies regardless of the sufficiency or the length of notice of Termination given by the Corporation or any Affiliate of the Corporation to the Optionee. 

Section 6.09. Disability of Optionee. Unless otherwise provided in the Equity Award Agreement relating to an Option, in the event
of a Termination as a result of the Optionee’s Disability, the Optionee may exercise the Option to the extent of the Shares in respect of which such Option is exercisable on the date notice of Termination is given to the Optionee by the
Corporation or any Affiliate of the Corporation at any time beginning on such date and ending on the earlier of (a) the date twelve (12) months after such notice of Termination is delivered to the Optionee, or (b) the expiration of
the term of the Option as set forth in the Equity Award Agreement. 
 Section 6.10. Death of Optionee. Unless otherwise
provided in the Equity Award Agreement relating to an Option, in the event of a Termination as a result of the Optionee’s death, the Optionee’s estate or a person who acquired the right to exercise the Option by bequest or inheritance may
exercise the Option to the extent of the Shares in respect of which such Option is exercisable on the date of death at any time beginning on such date and ending on the earlier of (a) the date twelve (12) months after the date of death, or
(b) the expiration of the term of the Option as set forth in the Equity Award Agreement.

 Section 6.11. Incentive Stock Option Limitations. The following limitations shall
apply to a grant of an Incentive Stock Option: 
 If, at the time of the grant of an Incentive Stock Option, the Optionee owns (or is
deemed to own pursuant to Section 424(d) of the Code) equity securities possessing more than ten percent (10%) of the total combined voting power of all classes of equity securities of the Corporation or of any of its Affiliates, the
exercise price of such Incentive Stock Option shall be at least one hundred and ten percent (110%) of the Fair Market Value of such Stock on the date of grant and the Incentive Stock Option shall terminate on the date that is within five
(5) years after the date of grant. 
 If the aggregate Fair Market Value (determined as of the time the Incentive Stock Option with
respect to such Stock is granted) of Stock with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any calendar year (under all plans of the Corporation and its Affiliates) exceeds one hundred thousand
dollars ($100,000), the Options or portions thereof that exceed such limit shall be treated as Non-statutory Stock Options. 

Section 6.12. Cancellation and Regrant. The Board shall have the authority to effect, at any time and from time to time,
(a) the repricing of any outstanding Options under the Plan, or (b) with the consent of the affected holders of Options, the cancellation of any outstanding Options under the Plan and the grant in substitution therefor of new Options under
the Plan covering the same or different numbers of shares of Stock and having an exercise price per share as determined by the Board. 

Section 6.13. Qualification of Incentive Stock Options. Anything in the Plan to the contrary notwithstanding, no term of the Plan
relating to Incentive Stock Options shall be interpreted, amended or altered, nor shall any discretion or authority granted under the Plan be exercised, so as to disqualify the Plan under Section 422 of the Code or, without the consent of the
Optionee affected, to disqualify any Incentive Stock Option under Section 422 of the Code.

Section 7.02. Purchase Price. The purchase price, if any, for any Stock granted as a Stock bonus or restricted Stock award shall
be such amount as the Board shall determine and designate in the Equity Award Agreement. Notwithstanding the foregoing, the Board may determine that eligible participants in the Plan may be awarded Stock in consideration for past services rendered
to the Corporation or an Affiliate thereof or for the benefit of the Corporation or an Affiliate thereof. Upon the award of any Stock bonus or restricted Stock award and the payment of any purchase price, if applicable, the holder of such Stock
bonus or restricted Stock award shall deliver to the Corporation a completed Stock Purchase Agreement. 
 Section 7.03.
Transferability. Unless otherwise provided in the Equity Award Agreement and subject to the provisions of any applicable buy-sell or similar agreements, Stock awarded or purchased pursuant to this Article VII shall not be transferable except by
will or by the laws of descent and distribution, or except in connection with a Corporate Transaction, until such time as any vesting restrictions and/or repurchase rights thereon shall lapse. 

  
 -6- 

 Section 7.04. Payment. Unless otherwise provided in the applicable Equity Award
Agreement, the purchase price, if any, of Stock acquired pursuant to a Stock bonus or restricted Stock award shall be paid in cash (by check) or, in the discretion of the Board, by promissory note (with terms determined by it in its discretion prior

 Section 7.05. Vesting. Subject to the provisions of the Plan, the
Board, in its discretion, shall determine whether shares of Stock sold or awarded under Article VII of the Plan shall be subject to vesting or to repurchase by the Corporation, and the time or times when such vesting restrictions and/or repurchase
rights shall lapse, and such determinations shall be set forth in the applicable Equity Award Agreement. An Equity Award may be subject to such other terms and conditions on the time or times when it may vest (which may be based on performance or
other criteria) as the Board may deem appropriate if expressly set forth in an Equity Award Agreement. Unless otherwise approved by the Board and set forth in writing by an authorized officer of the Corporation, a Stock bonus or restricted Stock
award shall cease vesting upon the holder’s Termination, and (if applicable) the right to acquire any Stock purchasable thereunder which has not been purchased by such time shall terminate, regardless of whether or not the holder was given
requisite notice of Termination of such holder’s employment by the Corporation or by any Affiliate of the Corporation. 

ARTICLE VIII 

ADJUSTMENTS UPON CHANGES IN STOCK; CORPORATE TRANSACTIONS 

Section 8.01. Change in Stock. If any change is made in the Stock subject to the Plan, through a merger, consolidation,
reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving
the receipt of consideration by the Corporation (other than a Corporate Transaction), the Plan will be appropriately adjusted in the class(es) and maximum number of shares subject to the Plan pursuant to Article V, and the outstanding Equity Awards
will be appropriately adjusted (to the extent not previously exercised by the holders thereof) in the class(es) and number of shares subject thereto and in the exercise price of such outstanding Equity Awards. If as a result of such event, a holder
of an Equity Award would become entitled to a fractional share of Stock or other security, such holder shall have the right to purchase only the next lowest whole number of shares of Stock or other security and no payment or other adjustment will be
made with respect to the fractional interest so disregarded. The Board shall make such adjustments at the time of the change in the Stock, whether or not specifically provided for in any outstanding Equity Award. The Board’s determination shall
be final, binding and conclusive. Notwithstanding the foregoing, any such adjustment shall be made only if and to the extent that such adjustment would not cause any Equity Award intended to qualify as an Incentive Stock Option to fail to so
qualify. 

  
 -7- 

 Section 8.02. Corporate Transaction. Unless the surviving corporation (or a parent or
subsidiary of such corporation) in the Corporate Transaction assumes this Plan or such Equity Award or issues a substitute therefor or unless the Board provides in substitution for any outstanding Equity Award such alternative consideration as it,
in good faith, may determine to be equitable in the circumstances, including cash, or unless otherwise provided in the Equity Award Agreement pursuant to which such Equity Award was originally granted, and subject to the provisions of
Section 10.01, the following shall apply in the event of a Corporate Transaction: 
 If such Equity Award is an Option, then it
shall terminate upon the effective date of the Corporate Transaction to the extent not exercised prior thereto. 
 If such Equity Award is a
Stock bonus or restricted Stock award, then (i) the vested portion thereof shall survive the Corporate Transaction and shall be subject to the terms and conditions of such Corporate Transaction (including, but not limited to, any terms and
conditions applicable to the sale, exchange, conversion or other disposition of such Stock bonus or Restricted Stock award in such Corporation Transaction), and (ii) the unvested portion thereof shall terminate upon the effective date of the
Corporate Transaction (provided that in connection with the consummation of such Corporate Transaction, the Corporation shall pay the holder thereof an amount equal to the purchase price (if any) originally paid by such holder for the Stock bonus or
Restricted Stock award so terminated). 
 (c) No Equity Award may be made after the effective date of the Corporate Transaction.

authorized but unissued Stock the number of shares of Stock issuable pursuant to outstanding Equity Awards.

Regulatory Authority. The Corporation shall seek to obtain from each regulatory commission or agency having jurisdiction over the Plan such authority as may be required to make an Equity Award and to issue and sell shares of Stock upon the
exercise of outstanding Equity Awards, provided that this undertaking shall not require the Corporation to register under the Securities Act or under any applicable state securities laws either the Plan, any Equity Award or any Stock issued or
issuable pursuant to any such Equity Award. If, after reasonable efforts, the Corporation is unable to obtain from any such regulatory commission or agency the authority for the lawful grant of any such Equity Award or the lawful issuance and sale
of Stock under the Plan, then, as the case may be, the Equity Award so granted shall be nullified or the Corporation shall be relieved from any liability for failure to issue and sell Stock upon exercise of such Equity Awards unless and until such
authority is obtained.

deemed to be the holder of, or to have any of the rights of a holder with respect to, any Stock subject to such Equity Award unless and until such person has satisfied all requirements for vesting or exercise of the Equity Award pursuant to its
terms and the amount due in payment for Stock to be issued pursuant to such Equity Award Agreement, if any, has been paid in full to the Corporation.

Award any right to act or to continue acting as a Director or Consultant, (c) affect the right of the Corporation or any Affiliate to terminate the employment of any Employee with or without Cause, (d) affect the right of the

and experience in financial and business matters, (c) that he or she is capable of evaluating, alone or together with a purchaser representative, the merits and risks of exercising the Equity Award,

advice of counsel to the Corporation, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the
transfer of the Stock. Notwithstanding anything to the contrary contained in this Plan or an Equity Award Agreement, no Stock shall be issued to a person pursuant to an Equity Award unless such shares of Stock are then registered under the
Securities Act and registered or qualified under all applicable state securities laws, or if such shares are not then so registered or qualified, the Corporation has determined that such issuance would be exempt from the registration requirements of
