 THIS DEED OF INDEMNIFICATION (this “Deed”) is made on [•] 2022 

BETWEEN: 
  

	(1)	 MARIADB PLC, an Irish public limited company with company number 606330 and with its registered office
located at 70 Sir John Rogerson’s Quay, Dublin 2, Ireland (the “Company”). 

 AND 

 

	(2)	 [DIRECTOR/OFFICER/EMPLOYEE] of [address of Director/Officer/Employee] (the
“Indemnitee”). 

 WHEREAS: 
  

	A.	 Highly skilled and competent persons are becoming more reluctant to serve public companies as directors,
officers and / or employees unless they are provided with adequate protection through insurance and indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of such
companies and uncertainties relating to indemnification increase the difficulty of attracting and retaining such persons. 

  

	B.	 The Board (as defined below) has determined that an inability to attract and retain such persons is detrimental
to the best interests of the Company and its shareholders and that the Company should act to assure such persons that there will be increased certainty of such protection. 

 

	C.	 The Company desires to ensure that the Company and its shareholders benefit from the services of highly skilled
and competent persons such as the Indemnitee. 

  

	D.	 It is reasonable, prudent and necessary for the Company to contractually obligate itself to indemnify the
Indemnitee to the Fullest Extent Permitted By Law so that the Indemnitee will serve or continue to serve the Company free from undue concern that the Indemnitee will not be so indemnified. 

 

	E.	 The Indemnitee is willing to serve, continue to serve and take on additional service for or on behalf of the
Company and, as partial consideration for agreeing to do so, the Company has agreed to enter into this Deed with the Indemnitee. 

 NOW

	3	 Indemnity of [Director / Officer / Employee] 

 

	3.1	 Subject to clause 10, the Company shall, to the Fullest Extent Permitted By Law and without prejudice to any
other indemnity to which the Indemnitee may otherwise be entitled, indemnify, defend and hold harmless the Indemnitee against all damages, losses, liabilities, judgments, penalties, fines, amounts paid in settlement, and reasonable Expenses if
lndemnitee was or is a party to or participant in, or is threatened to be made a party to or participant in, any Proceeding, including a Proceeding brought by or in the right of the Company, by reason of the fact or assertion that the Indemnitee
(i) is, or was, serving as a director, officer, employee, agent, or fiduciary of the Company or another Group Company or (ii) is or was serving, at the request of the Company or another Group Company, as a director, officer, employee,
agent, or fiduciary of any other company, corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other Entity or enterprise or by reason of anything done or not done by the Indemnitee in any such
capacity. 

  

	3.2	 Subject to clause 10, if the Indemnitee is entitled under any provision of this Deed to indemnification for
some or a portion of Expenses, damages, losses, liabilities, judgments, penalties, fines and amounts paid in settlement, but not the total amount thereof, the Company shall indemnify, defend and hold harmless the Indemnitee for such portion of the
Expenses, damages, losses, liabilities, judgments, penalties, fines, amounts paid in settlement and any other amounts that the lndemnitee becomes legally obligated to pay in connection with any Proceeding to which the lndemnitee is entitled.

  

	4	 Indemnification for Expenses of a Witness 

Subject to clause 10, to the extent that the Indemnitee is, by reason of the Indemnitee’s Corporate Status, a witness in any Proceeding,
the Indemnitee shall be indemnified by the Company against all Expenses actually and reasonably incurred by the lndemnitee or on the Indemnitee’s behalf in connection therewith. 

 

	5	 Determination of Entitlement to Indemnification 

 

	5.1	 The Indemnitee shall request indemnification pursuant to this Deed by notice in writing to the General Counsel
of the Company or, if not the same person, to the secretary of the Company. The secretary shall, promptly upon receipt of the Indemnitee’s request for indemnification, advise in writing the Board and the Board Designee or such other person or
persons empowered to make the determination as provided in clause 5.2 that the Indemnitee has made such request for indemnification. Subject to clause 10, upon making such request for indemnification, the Indemnitee shall be presumed to be entitled
to indemnification hereunder and the Company shall have the burden of proof in the making of any determination contrary to such presumption. 

  

	5.2	 Upon written request by the Indemnitee for indemnification pursuant to clause 3.1, the entitlement of the
lndemnitee to indemnification pursuant to the terms of this Deed shall be determined in the following circumstances and by the following person or persons who, in each instance, shall be empowered to make such determination: 

 

	 	5.2.1	 if a Change in Control shall not have occurred, 

  
 6 

	 	(a)	 by the Board, by a majority vote of the Disinterested Directors, or by the Board Designee; or

  

	 	(b)	 if such Board vote or the Board Designee determination under clause 5.2.1(a) is not obtainable or, even if
obtainable, if such Disinterested Directors (by majority vote) or the Board Designee so directs, by (i) Independent Counsel in a written opinion to the Board and the Board Designee, a copy of which shall be delivered to the Indemnitee; or
(ii) a majority vote of the shareholders of the Company; and 

  

	 	5.2.2	 if a Change in Control shall have occurred, 

 

	 	(a)	 by Independent Counsel in a written opinion to the Board and the Board Designee, a copy of which shall be
delivered to the Indemnitee; or 

  

	 	(b)	 at the Indemnitee’s sole option, the Indemnitee shall have the right to direct that such determination be
made in the manner provided in clause 5.2.1. 

  

	5.3	 For the purposes of clause 5.2.1(b), Independent Counsel shall be selected by the Board or the Board Designee
and reasonably approved by the lndemnitee and, for the purposes of clause 5.2.2, Independent Counsel shall be reasonably selected by the Indemnitee. Upon failure of the Board or the Board Designee to so select such Independent Counsel or upon
failure of the Indemnitee to so approve, such Independent Counsel shall be selected by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Such determination of entitlement to indemnification
shall be made not later than 60 days after receipt by the Company of a written request for indemnification. Such request shall include documentation or information which is reasonably necessary for such determination and which is reasonably
available to Indemnitee. Subject to clause 10, any reasonable Expenses incurred by the Indemnitee in connection with the Indemnitee’s request for indemnification hereunder shall be borne by the Company irrespective of the outcome of the
determination of the Indemnitee’s entitlement to indemnification. If the person or persons making such determination shall determine that the Indemnitee is entitled to indemnification as to part, but not all, of the application for
indemnification, such persons may, subject to clause 10, reasonably pro rate such partial indemnification among such claims, issues or matters in respect of which indemnification is requested. 

 

	6	 Advancement of Expenses 

Subject to clause 10, all reasonable Expenses incurred by, and advances of disbursements required of, the Indemnitee in connection with any
Proceeding and in connection with the Indemnitee seeking an adjudication or award in arbitration pursuant to this Deed shall, at the request of the Indemnitee, be paid by the Company in advance of the final disposition of any such Proceeding,
adjudication or arbitration as promptly as possible, and in any event within 20 days after the receipt by the Company of a statement or statements from the Indemnitee requesting such advance or advances from time to time. Such statement or
statements shall reasonably evidence the Expenses incurred by, or disbursements required of, the Indemnitee in connection therewith. Notwithstanding any determination as to entitlement to indemnification made pursuant to clauses 5 or 7, the
Indemnitee agrees that it will forthwith (and, in any event, not later than 20 days from the date the Company provides a written demand therefor) repay any advance of funds made by the Company pursuant to this clause 6 in the event of any allegation
of fraud or dishonesty in the relevant Proceeding is proved against the Indemnitee or 

  
 7 

 
if it is otherwise determined under applicable law that the Indemnitee is not entitled to be indemnified. Subject to clause 10, the Company shall have the burden of proof in any determination
under this clause 6. No amounts advanced hereunder shall be deemed an extension of credit by the Company to the Indemnitee. 
  

	7	 Remedies of Indemnitee in Cases of Determination Not to Indemnify or to Advance Expenses or Failure
to Timely Pay  

  

	7.1	 In the event that: (a) a determination is made that the lndemnitee is not entitled to indemnification
hereunder; (b) payment has not been timely made following a determination of entitlement to indemnification pursuant to clause 5; or (c) Expenses or disbursements required of the Indemnitee are not advanced pursuant to clause 6, the
lndemnitee shall be entitled to apply to a court of competent jurisdiction for a determination of the Indemnitee’s entitlement to such indemnification, indemnification payment or advance. 

 

	7.2	 Alternatively to clause 7.1, the lndemnitee, at the Indemnitee’s sole option, may seek an award in
arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association, such award to be made within 60 days following the Indemnitee’s filing of the request for arbitration. The
Company shall not oppose the Indemnitee’s right to seek any such adjudication or award in arbitration or any other claim. 

  

	7.3	 A judicial proceeding or arbitration pursuant to this clause 7 shall be made de novo and the Indemnitee shall
not be prejudiced by reason of a determination otherwise made hereunder (if so made) that the Indemnitee is not entitled to indemnification. If the court or arbitrator shall determine that the Indemnitee is entitled to any indemnification or advance
hereunder, the Company shall pay all reasonable Expenses actually incurred by the Indemnitee in connection with such adjudication or award in arbitration (including, but not limited to, any appellate proceedings) (the “Clause 7
Expenses”), provided however, that the lndemnitee agrees that it will forthwith (and, in any event, not later than 20 days from the date the Company provides a written demand therefor) repay such Clause 7 Expenses in the event that any
allegation of fraud or dishonesty is proved against the Indemnitee in the Proceeding in respect of which the Indemnitee was seeking indemnification or an advance of monies hereunder. 

 

	8	 Other Rights to Indemnification 

 

	8.1	 The indemnification and advancement of reasonable Expenses provided by this Deed shall not be deemed exclusive
of any other right to which the Indemnitee previously, now or in the future may be entitled under any provision of the Company’s memorandum or articles of association, any other agreement (including any agreement between the Indemnitee and any
other Group Company), vote of shareholders of the Company, the Board or Disinterested Directors, provision of law, or otherwise, provided that the Company shall not be obligated under this Deed to make any payment pursuant to this Deed for which
payment has been actually made to or on behalf of the Indemnitee by or on behalf of any of the Group Companies under any insurance policy or other indemnity provision, except in respect of any excess beyond the amount paid under any such insurance
policy or other indemnity provisions. 

  

	8.2	 In the event of any payment under this Deed, the Group Companies shall be subrogated to the extent of such
payment to all of the rights of recovery of the Indemnitee, who shall execute at the request of the Company all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the
Company to bring suit to enforce such rights. 

  
 8 

	9	 Attorneys’ Fees and Other Expenses to Enforce Deed 

In the event that the Indemnitee is subject to or intervenes in any Proceeding in which the validity or enforceability of this Deed is at issue
or seeks an adjudication or award in arbitration to enforce the Indemnitee’s rights under, or to recover damages for breach of, this Deed, the Indemnitee, if the Indemnitee prevails in whole or in part in such action, shall, subject to clause
10, be entitled to recover from the Company and shall be indemnified by the Company against, any actual Expenses reasonably incurred by the Indemnitee; provided that in bringing any action for adjudication or award in arbitration to enforce the
Indemnitee’s rights, the Indemnitee acted in good faith. 
  

	10	 Limitations of Indemnification 

 

	10.1	 Notwithstanding any other terms of this Deed, no provision of this Deed shall indemnify, the Indemnitee
against, or exempt the Indemnitee from, any liability for fraud or dishonesty proved against the Indemnitee. 

  

	10.2	 Notwithstanding any other terms of this Deed, no provision of this Deed shall indemnify the Indemnitee against,
or exempt the Indemnitee from, any liability to the extent such provision would be void under applicable law, including, without limitation, the provisions of section 235 of the Companies Act 2014 (but shall otherwise have effect to the Fullest
Extent Permitted By Law in effect at the relevant time). The Parties acknowledge that, at the date of this Deed, section 235 of the Companies Act renders void any provision, whether contained in the constitution of the Company, in a contract with
the Company (such as this Deed) or otherwise, purporting to exempt a director or other officer of the Company from, or purporting to indemnify a director or other officer of the Company against, any liability which by virtue of any enactment or rule
of law would otherwise attach to the Indemnitee in respect of any negligence, default, breach of duty or breach of trust of which the Indemnitee may be guilty in relation to the Company, provided that, notwithstanding the aforesaid prohibition, the
Company may indemnify a director or other officer against any liability incurred by the Indemnitee: (i) in defending proceedings, whether civil or criminal, in which judgment is given in the Indemnitee’s favour or in which
the Indemnitee is acquitted; or (ii) in connection with any proceedings or an application for relief from liability under section 233 or 234 of the Companies Act in which relief is granted to the Indemnitee by the High Court of
Ireland. 

  

	11	 Liability Insurance 

To the extent the Company maintains an insurance policy or policies providing directors’, officers’ and/or employees’ liability
insurance, the Indemnitee shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of the coverage available for any Company director, officer or employee. 

 

	12	 Duration of Deed 

This Deed shall apply with respect to the lndemnitee’s occupation of any of the position(s) described in clause 3.1 of this Deed prior to
the date of this Deed and with respect to all periods of such service after the date of this Deed, even though the Indemnitee may have ceased to occupy such positions(s). 

  
 9 

	13	 Notice of Proceedings by the Indemnitee 

 

	13.1	 The Indemnitee agrees promptly to notify the Company in writing upon being served with any summons, citation,
subpoena, complaint, indictment, information or other document relating to any Proceeding which may be subject to indemnification hereunder; provided that the failure to so notify the Company will not relieve the Company from any liability it may
have to the lndemnitee except to the extent that such failure materially prejudices the Company’s ability to defend such claim. With respect to any such Proceeding as to which the lndemnitee notifies the Company of the commencement thereof:

  

	 	13.1.1	 the Company will be entitled to participate therein at its own expense; and 

 

	 	13.1.2	 except as otherwise provided below, to the extent that it may wish, the Company jointly with any other
indemnifying party similarly notified will be entitled to assume the defence thereof, with counsel reasonably satisfactory to lndemnitee. After notice from the Company to the lndemnitee of its election so to assume the defence thereof, the Company
will not be liable to lndemnitee under this Deed for any Expenses subsequently incurred by the Indemnitee in connection with the defence thereof other than, subject to clause 10, reasonable costs of investigation or as otherwise provided below. The

 THIS INDEMNIFICATION AGREEMENT (this “Agreement”) is made on [•] 2022

 BETWEEN: 
  

	(1)	 MARIADB USA, INC., a Delaware corporation with its principal place of business at 699 Veterans Blvd.,
Redwood City, CA 94063 (the “Company”). 

 AND 

 

	(2)	 [DIRECTOR/OFFICER/EMPLOYEE] of [address of Director/Officer/Employee] (the
“Indemnitee”). 

 WHEREAS: 
  

	A.	 The Company is a wholly owned subsidiary of MariaDB plc, an Irish public limited company
(“Parent”). 

  

	B.	 The Board (as defined below) believes that it is in the Company’s best interests for Parent to attract and
retain highly skilled and competent directors, officers and employees due to direct and indirect benefits the Company derives or expects to derive from Parent as its wholly owned subsidiary, including access to capital and the ability to compensate
the Company’s employees and other service providers with equity awards exercisable for or settled in Parent’s publicly-traded shares, 

  

	C.	 Highly skilled and competent persons are reluctant to serve public companies as directors, officers and / or
employees unless they are provided with adequate protection through insurance and indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of such companies and
uncertainties relating to indemnification increase the difficulty of attracting and retaining such persons. 

  

	D.	 The Board has determined that Parent’s inability to attract and retain such persons is detrimental to the
best interests of the Company and Parent, as its sole shareholder, and that the Company should act to assure such persons that there will be increased certainty of such protection. 

 

	E.	 The Company desires to ensure that Parent and its shareholders, as well as the Company as a wholly owned
subsidiary of Parent, benefit from the services of highly skilled and competent persons such as the Indemnitee, and has requested that the Indemnitee serve as a [director, officer and / or employee] of Parent. 

 

	F.	 It is reasonable, prudent and necessary for the Company to contractually obligate itself to indemnify the
Indemnitee to the Fullest Extent Permitted By Law so that the Indemnitee will serve or continue to serve Parent free from undue concern that the Indemnitee will not be so indemnified. 

 

	G.	 The Indemnitee is willing to serve, continue to serve and take on additional service for or on behalf of Parent
and, as partial consideration for agreeing to do so, the Company has agreed to enter into this Agreement with the Indemnitee.

other indemnity to which the Indemnitee may otherwise be entitled, indemnify, defend and hold harmless the Indemnitee against all damages, losses, liabilities, judgments, penalties, fines, amounts paid in settlement, and reasonable Expenses if
lndemnitee was or is a party to or participant in, or is threatened to be made a party to or participant in, any Proceeding, by reason of the fact or assertion that the Indemnitee (i) is, or was, serving as a director, officer, employee, agent,
or fiduciary of Parent, the Company or another Group Company or (ii) is or was serving, at the request of the Company or another Group Company, as a director, officer, employee, agent, or fiduciary of any other company, corporation,

	3.2	 Subject to clause 10, if the Indemnitee is entitled under any provision of this Agreement to indemnification
for some or a portion of Expenses, damages, losses, liabilities, judgments, penalties, fines and amounts paid in settlement, but not the total amount thereof, the Company shall indemnify, defend and hold harmless the Indemnitee for such portion of
the Expenses, damages, losses, liabilities, judgments, penalties, fines, amounts paid in settlement and any other amounts that the lndemnitee becomes legally obligated to pay in connection with any Proceeding to which the lndemnitee is entitled.

  

	4	 Indemnification for Expenses of a Witness 

Subject to clause 10, to the extent that the Indemnitee is, by reason of the Indemnitee’s Corporate Status, a witness in any Proceeding,
the Indemnitee shall be indemnified by the Company against all Expenses actually and reasonably incurred by the lndemnitee or on the Indemnitee’s behalf in connection therewith. 

 

	5	 Determination of Entitlement to Indemnification 

 

	5.1	 The Indemnitee shall request indemnification pursuant to this Agreement by notice in writing to the secretary
of the Company. The secretary shall, promptly upon receipt of the Indemnitee’s request for indemnification, advise in writing the Board or such other person or persons empowered to make the determination as provided in clause 5.2 that the
Indemnitee has made such request for indemnification. Subject to clause 10, upon making such request for indemnification, the Indemnitee shall be presumed to be entitled to indemnification hereunder and the Company shall have the burden of proof in
the making of any determination contrary to such presumption. 

  
 6 

	5.2	 Upon written request by the Indemnitee for indemnification pursuant to clause 3.1, the entitlement of the
lndemnitee to indemnification pursuant to the terms of this Agreement shall be determined in the following circumstances and by the following person or persons who, in each instance, shall be empowered to make such determination:

  

	 	5.2.1	 if a Change in Control shall not have occurred, 

 

	 	(a)	 by the Board, by a majority vote of the Disinterested Directors, even though less than a quorum;

  

	 	(b)	 by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even
though less than a quorum; 

  

	 	(c)	 if there are no Disinterested Directors, or if such Disinterested Directors (by majority vote) so direct, by
(i) Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee; or (ii) a majority vote of the shareholders of the Company; and 

 

	 	5.2.2	 if a Change in Control shall have occurred, 

 

	 	(a)	 by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee;
or 

  

	 	(b)	 at the Indemnitee’s sole option, the Indemnitee shall have the right to direct that such determination be
made in the manner provided in clause 5.2.1. 

  

	5.3	 For the purposes of clause 5.2.1(b), Independent Counsel shall be selected by the Board and reasonably approved
by the lndemnitee and, for the purposes of clause 5.2.2, Independent Counsel shall be reasonably selected by the Indemnitee. Upon failure of the Board to so select such Independent Counsel or upon failure of the Indemnitee to so approve, such
Independent Counsel shall be selected by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Such determination of entitlement to indemnification shall be made not later than 60 days after
receipt by the Company of a written request for indemnification. Such request shall include documentation or information which is reasonably necessary for such determination and which is reasonably available to Indemnitee. Subject to clause 10, any
reasonable Expenses incurred by the Indemnitee in connection with the Indemnitee’s request for indemnification hereunder shall be borne by the Company irrespective of the outcome of the determination of the Indemnitee’s entitlement to
indemnification. If the person or persons making such determination shall determine that the Indemnitee is entitled to indemnification as to part, but not all, of the application for indemnification, such persons may, subject to clause 10,
reasonably pro rate such partial indemnification among such claims, issues or matters in respect of which indemnification is requested. 

  
 7 

	6	 Advancement of Expenses 

Subject to clause 10, all reasonable Expenses incurred by, and advances of disbursements required of, the Indemnitee in connection with any
Proceeding and in connection with the Indemnitee seeking an adjudication or award in arbitration pursuant to this Agreement shall, at the request of the Indemnitee, be paid by the Company in advance of the final disposition of any such Proceeding,
adjudication or arbitration as promptly as possible, and in any event within 20 days after the receipt by the Company of a statement or statements from the Indemnitee requesting such advance or advances from time to time. Such statement or
statements shall reasonably evidence the Expenses incurred by, or disbursements required of, the Indemnitee in connection therewith. Notwithstanding any determination as to entitlement to indemnification made pursuant to clauses 5 or 7, the
Indemnitee agrees that it will forthwith (and, in any event, not later than 20 days from the date the Company provides a written demand therefor) repay any advance of funds made by the Company pursuant to this clause 6 if it is ultimately determined
under applicable law that the Indemnitee is not entitled to be indemnified. The parties intend that the foregoing constitute the undertaking required pursuant to Section 145(e) of the Delaware General Corporation Law. Subject to clause 10, the
Company shall have the burden of proof in any determination under this clause 6. No amounts advanced hereunder shall be deemed an extension of credit by the Company to the Indemnitee. 

 

	7	 Remedies of Indemnitee in Cases of Determination Not to Indemnify or to Advance Expenses or Failure
to Timely Pay  

  

	7.1	 In the event that: (a) a determination is made that the lndemnitee is not entitled to indemnification
hereunder; (b) payment has not been timely made following a determination of entitlement to indemnification pursuant to clause 5; or (c) Expenses or disbursements required of the Indemnitee are not advanced pursuant to clause 6, the
lndemnitee shall be entitled to apply to an appropriate court of the State of Delaware for a determination of the Indemnitee’s entitlement to such indemnification, indemnification payment or advance. 

 

	7.2	 Alternatively to clause 7.1, except for an application to be indemnified for any liability arising from a
Proceeding by or in the right of the Company for which the Indemnitee shall have been adjudicated liable (which must be brought in the Court of Chancery of the State of Delaware or the court in which such Proceeding was brought), the lndemnitee, at
the Indemnitee’s sole option, may seek an award in arbitration to be conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association, such award to be made within 60 days following the
Indemnitee’s filing of the request for arbitration. The Company shall not oppose the Indemnitee’s right to seek any such adjudication or award in arbitration or any other claim. 

 

	7.3	 A judicial proceeding or arbitration pursuant to this clause 7 shall be made de novo and the Indemnitee shall
not be prejudiced by reason of a determination otherwise made hereunder (if so made) that the Indemnitee is not entitled to indemnification. If the court or arbitrator shall determine that the Indemnitee is entitled to any indemnification or advance
hereunder, the Company shall pay all reasonable Expenses actually incurred by the Indemnitee in connection with such adjudication or award in arbitration (including, but not limited to, any appellate proceedings) (the “Clause 7
Expenses”), provided however, that the lndemnitee agrees that it will forthwith (and, in any event, not later than 20 days from the date the Company provides a written demand therefor) repay such Clause 7 Expenses in the event that any
allegation of fraud or dishonesty is proved against the Indemnitee in the Proceeding in respect of which the Indemnitee was seeking indemnification or an advance of monies hereunder.

	8	 Other Rights to Indemnification 

 

	8.1	 The indemnification and advancement of reasonable Expenses provided by this Agreement shall not be deemed
exclusive of any other right to which the Indemnitee previously, now or in the future may be entitled under any provision of the Company’s certificate of incorporation, bylaws, any other agreement (including the Parent Deed of Indemnification
or any agreement between the Indemnitee and any other Group Company), vote of shareholders of the Company, the Board or Disinterested Directors, provision of law, or otherwise, provided that the Company shall not be obligated under this Agreement to
make any payment pursuant to this Agreement for which payment has been actually made to or on behalf of the Indemnitee by or on behalf of any of the Group Companies under any insurance policy or other indemnity provision, except in respect of any
excess beyond the amount paid under any such insurance policy or other indemnity provisions. As between Parent and the Company, Parent shall be the indemnitor of first resort (i.e., its obligations to the Indemnitee are primary and the obligations
of the Company to advance Expenses and to provide indemnification for the same Expenses, damages, losses, liabilities, judgments, penalties, fines, and amounts paid in settlement are secondary). To the extent not satisfied by Parent in accordance
with the Parent Indemnification Agreement, the Company shall be required to advance the full amount of Expenses incurred by the Indemnitee and shall be required to indemnify the Indemnitee for the full amount of damages, losses, liabilities,
judgments, penalties, fines, amounts paid in settlement, and reasonable Expenses in settlement as required by (and subject to) the terms of this Agreement, the Company’s certificate of incorporation or bylaws, or any other agreement between the
Company and the Indemnitee, without regard to any rights to indemnification or advancement of Expenses the Indemnitee may have against other Entities (other than Parent). 

 

	8.2	 In the event of any payment under this Agreement, the Group Companies shall be subrogated to the extent of such
payment to all of the rights of recovery of the Indemnitee, who shall execute at the request of the Company all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the
Company to bring suit to enforce such rights. 

  

	9	 Attorneys’ Fees and Other Expenses to Enforce Agreement 

In the event that the Indemnitee is subject to or intervenes in any Proceeding in which the validity or enforceability of this Agreement is at
issue or seeks an adjudication or award in arbitration to enforce the Indemnitee’s rights under, or to recover damages for breach of, this Agreement, the Indemnitee, if the Indemnitee prevails in whole or in part in such action, shall, subject
to clause 10, be entitled to recover from the Company and shall be indemnified by the Company against, any actual Expenses reasonably incurred by the Indemnitee; provided that in bringing any action for adjudication or award in arbitration to
enforce the Indemnitee’s rights, the Indemnitee acted in good faith. 
  

	10	 Limitations of Indemnification 

 

	10.1	 Notwithstanding any other terms of this Agreement, no provision of this Agreement shall indemnify, the
Indemnitee against, or exempt the Indemnitee from, any liability for bad faith, fraud or dishonesty proved against the Indemnitee. 

  
 9 

	10.2	 Notwithstanding any other terms of this Agreement, no provision of this Agreement shall indemnify the
Indemnitee against, or exempt the Indemnitee from, any liability arising in connection with a Proceeding by or in the right of the Company if the Indemnitee is adjudged liable to the Company unless and only to the extent that the Court of Chancery
of the State of Delaware (or the court in which such Proceeding was brought) determines that despite the adjudication of liability but in view of all the circumstances of the case, the Indemnitee is fairly and reasonably entitled to indemnification
for such Expenses that such court shall deem proper. 

  

	11	 Liability Insurance 

To the extent the Company or Parent maintains an insurance policy or policies providing directors’, officers’ and/or employees’
liability insurance, the Indemnitee shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of the coverage available for any Parent director, officer or employee. 

 

	12	 Duration of Agreement 

This Agreement shall apply with respect to the lndemnitee’s occupation of any of the position(s) described in clause 3.1 of this Agreement
prior to the date of this Agreement and with respect to all periods of such service after the date of this Agreement, even though the Indemnitee may have ceased to occupy such positions(s). 

 

	13	 Notice of Proceedings by the Indemnitee 

 

	13.1	 The Indemnitee agrees promptly to notify the Company in writing upon being served with any summons, citation,
subpoena, complaint, indictment, information or other document relating to any Proceeding which may be subject to indemnification hereunder; provided that the failure to so notify the Company will not relieve the Company from any liability it may
have to the lndemnitee except to the extent that such failure materially prejudices the Company’s ability to defend such claim. With respect to any such Proceeding as to which the lndemnitee notifies the Company of the commencement thereof:

  

	 	13.1.1	 the Company will be entitled to participate therein at its own expense; and 

 

	 	13.1.2	 except as otherwise provided below, to the extent that it may wish, the Company jointly with any other
indemnifying party similarly notified will be entitled to assume the defense thereof, with counsel reasonably satisfactory to lndemnitee. After notice from the Company to the lndemnitee of its election so to assume the defense thereof, the Company
will not be liable to lndemnitee under this Agreement for any Expenses subsequently incurred by the Indemnitee in connection with the defense thereof other than, subject to clause 10, reasonable costs of investigation or as otherwise provided below.
The lndemnitee shall have the right to employ the Indemnitee’s own counsel in such Proceeding, but the fees and Expenses of such counsel incurred after notice from the Company of its assumption of the defense thereof shall be at the expense of
Indemnitee and not subject to indemnification hereunder unless (a) the employment of counsel by the Indemnitee has been authorized by the Company; (b) in the reasonable opinion of counsel to the Indemnitee there is or may be a conflict of
interest between the Company and the Indemnitee in the conduct of the defense of such Proceeding; or (c) the Company shall not in fact have employed counsel to assume the defense of such action, in each of which cases, subject to clause 10, the
reasonable Expenses of counsel shall be at the expense of the Company. 

  

	13.2	 Neither the Company nor the Indemnitee shall settle any claim without the prior written consent of the other
(which shall not be unreasonably withheld, conditioned or delayed). 

  
 10 

	14	 Notices 

Any notice required to be given hereunder shall be in writing in the English language and shall be served by sending the same by prepaid
recorded post, facsimile, email or by delivering the same by hand to the address of the Party or Parties in question as set out below (or such other address as such Party or Parties shall notify the other Parties of in accordance with this clause
14). Any notice sent by post as provided in this clause 14 shall be deemed to have been served five Business Days after dispatch and any notice sent by facsimile or email as provided in this clause 14 shall be deemed to have been served at the time
of dispatch and in proving the service of the same it will be sufficient to prove in the case of a letter that such letter was properly stamped, addressed and placed in the post; and in the case of a facsimile or email that such facsimile or email
was duly dispatched to a current facsimile number or email address of the addressee.

	15.1	 Notwithstanding the expiration or termination of this Agreement howsoever arising; such expiration or
termination shall not operate to affect such of the provisions hereof as are expressed or intended to remain in full force and effect. 

  

	15.2	 If any of the clauses, conditions, covenants or restrictions of this Agreement or any agreement or document
emanating from it shall be found to be void but would be valid if some part thereof were deleted or modified, then such clause, condition, covenant or restriction shall apply with such deletion or modification as may be necessary to make it valid
and effective so as to give effect as nearly as possible to the intent manifested by such clause, condition, covenant or restriction. 

  

	15.3	 This Agreement shall be binding upon the Company and its successors and assigns (including any transferee of
all or substantially all of its assets and any successor or resulting company by any Corporate Transaction or otherwise) and shall inure to the benefit of the lndemnitee and the Indemnitee’s spouse, assigns, heirs, estate, devises, executors,
administrators or other legal representatives. 

  

	15.4	 This Agreement constitutes the entire agreement between the Parties relating to the matters covered hereby;
provided that this Agreement shall not supersede any other indemnification agreement between the Indemnitee and the Company or any Group Company (other than the Company) or any indemnification obligation of the Company or any Group Company to the
Indemnitee. 

  
 11 

	15.5	 No provision in this Agreement may be amended unless such amendment is agreed to in writing and signed by the
lndemnitee and by a duly authorized officer of the Company. No waiver by either Party of any breach by the other Party of any condition or provision of this Agreement to be performed by such other Party shall be deemed a waiver of any other
condition or provision hereof (whether similar or dissimilar) nor shall such waiver constitute a continuing waiver. Any waiver must be in writing and signed by the Indemnitee or a duly authorized officer of the Company, as the case may be.

  

	15.6	 This Agreement may be executed in any number of counterparts, including fax and email and by the different
Parties hereto on separate counterparts, each of which when executed and delivered shall constitute an original and all such counterparts together constituting but one and the same Agreement. This Agreement shall become effective and dated on the
date stated at the beginning of it. Transmission of an executed counterpart of this Agreement or the executed signature page of a counterpart of this Agreement by email (in PDF, JPEG or other legible format) shall take effect as delivery of an

or proceedings (“Agreement Proceedings”) which may arise out of or in connection with this Agreement and waive any objection to Agreement Proceedings in the courts of Delaware on the grounds of venue or on the basis that the
Agreement Proceedings have been brought in an inconvenient forum; provided that any matters that are referred to arbitration pursuant to clause 5.3 or 7.2 shall be exclusively determined by such arbitral proceedings which shall be conducted by a
single arbitrator, in the English language and in California, U.S.A. 

  

	15.8	 All payments made by the Company to the lndemnitee hereunder shall be deemed to have been made in the ordinary
course of business of the Company and shall not be deemed to be extraordinary payments. 

  

	15.9	 The Company expressly confirms and agrees that it has entered into this Agreement and assumed the obligations
imposed on it hereby in order to induce the Indemnitee to serve, continue to serve and to take on additional service for or on behalf of the Company, and the Company acknowledges that the Indemnitee is relying upon this Agreement in serving,
continuing to serve and taking on additional service for or on behalf of the Company.
