 5 








 SECTION 3. INDEMNIFICATION 

3.1 Indemnification in Third Party
Actions. Subject to the terms and conditions of this Agreement, in the event that the Indemnitee is a party to, is threatened to be made a party to, is a witness or other participant in, or is threatened to be made a witness or
other participant in, or is otherwise involved or threatened to be otherwise involved in any Proceeding by reason of, relating to or otherwise arising in whole or in part out of, an Indemnifiable Event (other than a Proceeding by or in the name of
the Company to procure a judgment in its favor which is addressed in Section 3.2 below), the Company shall indemnify the Indemnitee against all Indemnified Costs actually and reasonably incurred by Indemnitee in connection with such Proceeding,
to the fullest extent permitted by applicable law (whether or not such Proceeding proceeds to a judgment or is settled or is otherwise brought to final disposition) if the Indemnitee acted in good faith and in a manner the Indemnitee reasonably
believed to be in or not opposed to the best interests of the Company and, with respect to any criminal proceeding, had no reason to believe that his or her conduct was unlawful. 

3.2 Indemnification in Proceedings By
or In the Name of the Company. Subject to the terms and conditions of this Agreement, in the event that
the Indemnitee is a party to, is threatened to be made a party to, is a witness or other participant in, or is threatened to be a witness or other participant in, or is otherwise involved or threatened to be otherwise involved in any Proceeding by
or in the name of the Company to procure a judgment in its favor by reason of, relating to or otherwise arising in whole or in part out of, an Indemnifiable Event, the Company shall indemnify the Indemnitee against all Expenses actually and
reasonably incurred by Indemnitee in connection with such Proceeding, to the fullest extent permitted by applicable law (whether or not such Proceeding proceeds to a judgment or is settled or is otherwise brought to final disposition) if the
Indemnitee acted in good faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however that no indemnification against such Expenses shall be made in respect of
any claim, issue or matter in such Proceeding as to which the Indemnitee shall have been adjudged liable to the Company unless and to the extent that a court of competent jurisdiction determines that, despite such judgment, the Indemnitee is
entitled to indemnification hereunder. 
 3.3 Partial Indemnification. If the Indemnitee is
entitled under any provision of this Agreement to indemnification by the Company for some or a portion of, but not the total amount of, the Indemnified Costs, the Company shall nevertheless indemnify the Indemnitee for the portion of the Indemnified
Costs to which the Indemnitee is entitled. 
 3.4 Indemnification Hereunder
Not Exclusive. The indemnification provided by this Agreement is not exclusive of any other rights to which the Indemnitee may be entitled under the Company’s Certificate of Incorporation, its Bylaws, any
agreement, any vote of stockholders or Disinterested Directors, applicable law, or otherwise, both as to action in the Indemnitee’s official capacity and as to action in another capacity on behalf of the Company. 

3.5 Indemnification of Expenses of
Successful Party. Notwithstanding any other provisions of this Agreement, to the extent that the Indemnitee has been successful in defense of any Proceeding or in defense of any claim, issue or matter in a
Proceeding, on the merits or otherwise, including, but not limited to, the dismissal of a Proceeding (or any claim, issue or 

  
 6 








 
matter in a Proceeding) without prejudice, the Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee in connection with the Proceeding, claim, issue
or matter (as the case may be) that is successfully resolved to the fullest extent permitted by applicable law. 
 3.6
Advances of Expenses; Enforcement Proceedings. 

(a) The Indemnitee shall have the right to advancement by the Company, prior to the final disposition of any Proceeding by final adjudication
as to which there are no further rights of appeal and without the need for any Standard of Conduct Determination prior to such advancement, of any and all Expenses actually and reasonably paid or incurred by Indemnitee in connection with such
Proceeding to the fullest extent permitted by applicable law. Subject to the terms of this Agreement and any restrictions of applicable law, the advances to be made will be paid by the Company to the Indemnitee within thirty (30) days following
delivery to the Company of written request therefor from the Indemnitee which is accompanied by substantiating documentation reasonably satisfactory to the Company. Execution and delivery of this Agreement by the Indemnitee constitutes an
undertaking by the Indemnitee to repay any amounts paid, advanced or reimbursed by the Company in respect of Expenses pursuant to this Section 3.6 (“Advanced Expenses”) relating to, arising out of or resulting from, any
Proceeding with respect to which it shall be determined, following final disposition of such Proceeding, that Indemnitee is not entitled to indemnification hereunder. No other form of undertaking shall be required hereunder other than execution of
this Agreement. Advances shall be unsecured and interest free and shall be made without regard to the Indemnitee’s ability to repay the Advanced Expenses. The Company acknowledges the potentially severe damage to Indemnitee should the Company
fail timely to make such advances to Indemnitee. 
 (b) To the fullest extent allowable under applicable law, the Company shall also
indemnify the Indemnitee against, and, if requested by the Indemnitee, advance to the Indemnitee, subject to and in accordance with Section 3.6(a), any Expenses actually and reasonably paid or incurred by Indemnitee in connection with any action,
claim, suit or proceeding brought by Indemnitee to enforce Indemnitee’s right to indemnification or reimbursement (or advancement) of Indemnified Costs under any provision of this Agreement (any such action, claim, suit or proceeding, an
“Enforcement Proceeding”) unless the Delaware Court determines that each of the material claims and/or defenses of the Indemnitee in the Enforcement Proceeding was made in bad faith or was frivolous; provided,
however, that in the event that Indemnitee is ultimately determined not to be entitled to indemnification or reimbursement (or advancement) of the Indemnified Costs that were the subject of the Enforcement Proceeding, then all amounts
advanced to indemnify or reimburse Indemnitee for Expenses incurred in connection with the Enforcement Proceeding shall repaid by the Indemnitee to the Company. 

3.7 Limitations on Indemnification. (a) Notwithstanding anything in this
Agreement to the contrary, no payments pursuant to this Agreement shall be made by the Company to: 
 (i) indemnify, hold
harmless or advance Indemnified Costs to the Indemnitee with respect to any Proceeding (or any claim, issue or matter in a Proceeding) 

  
 7 








 
initiated or brought voluntarily by the Indemnitee (including any Proceeding, or claim, issue or matter in a Proceeding, against the Company or any of its directors, officers, employees or other
indemnitees) and not by way of defense, except for Expenses for which the Company is required to indemnify the Indemnitee in connection with Enforcement Proceedings pursuant to and in accordance with Section 3.6(b); provided, however,
that indemnification or advancement of Indemnified Costs may be provided by the Company with respect to a Proceeding (or any claim, issue or matter in a Proceeding) initiated or brought voluntarily by the Indemnitee and not by way of defense if
(i) the Board has consented to the initiation of such Proceeding (or such claim, issue or matter in a Proceeding) prior to its initiation, or (ii) such indemnification is expressly required to be made by applicable law. 

(ii) indemnify the Indemnitee for any Indemnified Costs sustained in any Proceeding for an accounting of profits made from the
purchase or sale by the Indemnitee of securities of the Company pursuant to the provisions of Section 16(b) of the Exchange Act, the rules and regulations promulgated thereunder and amendments thereto or similar provisions of any federal, state or
local statutory law; 
 (iii) indemnify the Indemnitee for any Indemnified Costs on account of conduct that is established by
a final judgment of a court of competent jurisdiction to constitute (i) willful misconduct by the Indemnitee or a breach of Indemnitee’s duty of loyalty to the Company, (ii) bad faith by the Indemnitee or (iii) fraud or
deliberate dishonesty of the Indemnitee; 
 (iv) indemnify the Indemnitee for any Indemnified Costs in connection with any
Proceeding (or claim, issue or matter in a Proceeding) based upon or attributable to Indemnitee gaining any personal profit or advantage to which Indemnitee is not entitled or for the return by Indemnitee of any remuneration paid to Indemnitee to
which Indemnitee is determined not to be entitled; or 
 (iv) indemnify the Indemnitee under this Agreement if a court of
competent jurisdiction shall finally determine that such payment is not permitted by applicable law. 
 (b) Notwithstanding anything herein
to the contrary, the Company shall not be obligated pursuant to the terms of this Agreement to indemnify or hold harmless Indemnitee in violation of, or to otherwise act in violation of, any undertaking appearing in and required by the rules and
regulations promulgated under the Securities Act, or in any registration statement filed with the SEC under the Securities Act. Indemnitee acknowledges that paragraph (h) of Item 512 of Regulation S-K
currently generally requires the Company to undertake in connection with any registration statement filed under the Securities Act to submit the issue of the enforceability of Indemnitee’s rights under this Agreement in connection with any
liability under the Securities Act on public policy grounds to a court of appropriate jurisdiction and to be governed by any final adjudication of such issue. Indemnitee specifically agrees that any such undertaking shall supersede the provisions of
this Agreement and to be bound by any such undertaking. 
 (c) Indemnitee hereby expressly undertakes and agrees to reimburse the Company
for all Indemnified Costs paid by the Company to or on behalf of Indemnitee in connection with any Proceeding in the event and only to the extent that it is finally determined by a court of competent jurisdiction in a decision from which there is no
further right of appeal that Indemnitee is not entitled to be indemnified by the Company for such Indemnified Costs because such Indemnified Costs relate to an Excluded Claim. 

  
 8 








 SECTION 4. STANDARD OF CONDUCT DETERMINATIONS 

4.1 Standard of Conduct Determination. To the
extent that the provisions of Section 3.5 are inapplicable to any Proceeding, any determination of whether the Indemnitee has satisfied the applicable standard of conduct that is a required condition to indemnification hereunder with respect to
such Proceeding (any such determination, a “Standard of Conduct Determination”) and any determination that Advanced Expenses must be repaid to the Company shall be made as follows: 

(a) if no Change in Control has occurred, such determination shall be made (1) by a majority vote of Disinterested Directors, even if
less than a quorum of the Board, or (2) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum; provided, however, that if there are no such
Disinterested Directors, such determination shall be made by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee. 

(b) if a Change in Control has occurred, such determination shall be made (1) if the Indemnitee so requests in writing, by a majority
vote of Disinterested Directors, though less than a quorum of the Board, or (2) otherwise by Independent Counsel in a written opinion addressed to the Board, a copy of which shall be delivered to Indemnitee. 

4.2 Timing of Standard of Conduct
Determination. The Company shall use its reasonable best efforts to cause any Standard of Conduct Determination required by Section 4.1 to be made as promptly as practicable. If the person or persons designated to make such
Standard of Conduct Determination shall not have made the determination within sixty (60) days after (i) receipt by the Company of a written request from Indemnitee for indemnification pursuant to Section 6 (the date of such receipt,
the “Notification Date”) if the Standard of Conduct Determination is to be made by Disinterested Directors, or (ii) the selection of an Independent Counsel if the Standard of Conduct Determination is to be made by
Independent Counsel, then Indemnitee shall be deemed to have satisfied the applicable standard of conduct, provided that such sixty (60)-day time period may be extended for a reasonable period of time, not to
exceed thirty (30) additional days, if the person or persons making such Standard of Conduct Determination in good faith require such additional time to obtain or evaluate information relating thereto. Notwithstanding anything herein to the
contrary, no determination as to the entitlement of Indemnitee to indemnification under this Agreement shall be required to be made prior to the final disposition of any Proceeding. 

4.3. Presumptions; Defenses. No determination by the Company (including by its directors or
any Independent Counsel) that Indemnitee has not satisfied any applicable standard of conduct shall create a presumption that Indemnitee is not entitled to indemnification 

  
 9 








 
hereunder. Any Standard of Conduct Determination that is adverse to Indemnitee may be challenged by Indemnitee in the Delaware Court. It shall be a defense to any Enforcement Proceeding brought
by Indemnitee (other than an action brought to enforce a claim for Expenses incurred in defending against a Proceeding in advance of its final disposition) that it is not permissible under applicable law for the Company to indemnify Indemnitee for
the amount claimed. In connection with any such Enforcement Action or any related Standard of Conduct Determination under Section 4.1, the burden of proving that Indemnitee is not entitled to indemnification shall be on the Company. For
purposes of this Agreement, the termination of any Proceeding by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that
Indemnitee did not meet any particular standard of conduct or have any particular belief or that a court has determined that indemnification is not permitted by applicable law. 

4.4 Payment. If, in regard to any Indemnified Costs: 

(a) Indemnitee shall be entitled to indemnification pursuant to Section 3.5; 

(b) no Standard of Conduct Determination is legally required as a condition to indemnification of Indemnitee hereunder; or 

(c) Indemnitee has been determined or deemed, pursuant to Section 4.1 or 4.2 above, to have satisfied the applicable Standard of Conduct;

 then, without duplication of any such Indemnified Costs that have been advanced to Indemnitee pursuant to Section 3.6, the Company
shall pay to Indemnitee, within thirty (30) days after the later of (A) written request for such Indemnifiable Costs made by Indemnitee to the Company which is accompanied by substantiating documentation reasonably satisfactory to the
Company, and (B) the earliest date on which the applicable criterion specified in clause (a), (b) or (c) is satisfied, an amount equal to such Indemnified Costs. 

SECTION 5. Selection of Independent Counsel.
If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 4.1 hereof, the Independent Counsel shall be selected by the Board by written notice to Indemnitee. Indemnitee may, within ten
(10) days after such written notice of selection shall have been given to Indemnitee, deliver to the Company a written objection to such selection; provided, however, that such objection may be asserted only on the ground that the
Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in the definition thereof, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and
timely objection, the person so selected shall act as Independent Counsel. If a written objection is timely and properly made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is
withdrawn or the Delaware Court has determined that such objection is without merit. Any Independent Counsel that has been selected by the Board without timely and proper objection from the Indemnitee or with respect to which any timely and proper
objection by the Indemnitee has been withdrawn, is referred to herein as an “Approved Independent Counsel”. If there is no Approved Independent Counsel by 5:00 p.m. eastern time on the date that is twenty
(20) days after 

  
 10 








 
submission by Indemnitee of a written request for indemnification pursuant to Section 6.1 hereof with respect to which a Standard of Conduct Determination is required to be made by
Independent Counsel pursuant to Section 4.1, either the Company or Indemnitee may petition the Delaware Court for resolution of any objection which shall have been made by the Indemnitee to the Board’s selection of Independent Counsel
and/or for the appointment as Independent Counsel of a person selected by the Delaware Court or by such other person as the Delaware Court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed
shall act as Independent Counsel under Section 4.1 hereof. The Company shall pay any and all reasonable fees and expenses incurred by the Independent Counsel in connection with acting pursuant to Section 4.1 hereof, and the Company shall
pay all reasonable fees and expenses incident to the procedures of this Section 5, regardless of the manner in which such Independent Counsel was selected or appointed. 

SECTION 6. INDEMNIFICATION PROCEDURE 

6.1 Notice. Promptly after receipt by the Indemnitee of notice of the commencement of any Proceeding, the Indemnitee
will, if a claim is to be made against the Company under this Agreement, notify the Company of the commencement of the Proceeding and make a request for indemnification hereunder (the date on which such notice and request is delivered to the
Company, the “Notification Date”), which notice and request shall contain a brief description of the Proceeding and include such documentation and information as is reasonably available to Indemnitee and is reasonably
necessary to determine whether and to what extent Indemnitee is entitled to indemnification hereunder. The failure to so notify the Company will not relieve the Company from any liability which the Company may have to the Indemnitee, except to the
extent the Company is materially damaged by the failure of the Indemnitee to so notify the Company. Indemnitee agrees not to make any admission or effect any settlement with respect to any such Proceeding without the consent of the Company. If, as
of the Notification Date, the Company has D&O Insurance in effect, the Company shall give prompt notice of the Proceeding to its insurers in accordance with the procedures set forth in the applicable policies. The Company shall thereafter use
commercially reasonable efforts to cause such insurers to pay, on behalf of Indemnitee, all Indemnifiable Costs relating to such Proceeding in accordance with the terms of such policies. The Company shall provide to the Indemnitee: (i) copies
of all potentially applicable D&O Insurance, (ii) a copy of such notice delivered to the applicable insurers, and (iii) copies of all subsequent correspondence between the Company and such insurers regarding the Proceeding, in each
case substantially concurrently with the delivery or receipt thereof by the Company. 
 6.2 Defense
of Claims. With respect to any Proceeding for which indemnification is requested by Indemnitee under this Agreement, the Company will be entitled to participate in the Proceeding at its own expense and, except
as otherwise provided below or pursuant to the terms of any applicable D&O Insurance, to the extent that it may desire, the Company may, upon written notice to Indemnitee within thirty (30) days after the Notification Date, assume and
control the defense of the Proceeding, with counsel reasonably satisfactory to the Indemnitee. After the Company notifies the Indemnitee of the Company’s election to assume and control the defense of a Proceeding, during the Company’s good
faith active defense of such Proceeding, the Company will not be liable to the Indemnitee under this Agreement for any legal or other expenses subsequently incurred by the Indemnitee in connection with the defense or settlement


  
 11 








 
of the Proceeding, other than reasonable expenses of investigation or as specifically provided below. The Indemnitee shall have the right to employ separate counsel for the Indemnitee in any
Proceeding but the fees and expenses of such counsel incurred after notice from the Company of its assumption of control of the defense of the Proceeding shall be at the expense of the Indemnitee, unless (i) the employment of counsel by the

(b) otherwise adequately provide for the satisfaction of the Company’s obligations under this Agreement in a manner reasonably acceptable to Indemnitee. 

8.2 Separability. Each provision of this Agreement is a separate and distinct agreement and independent of the others, so
that if any provision of this Agreement shall be held to be invalid or unenforceable for any reason, the invalidity or unenforceability shall not affect the validity or enforceability of the other provisions of this Agreement. To the extent
required, any provision of this Agreement may be modified by the Delaware Court to preserve its validity and to provide the Indemnitee with the broadest possible indemnification permitted under applicable law. 

8.3 Savings Clause. If this Agreement or any portion of it is invalidated on any ground by the
Delaware Court, then the Company shall nevertheless indemnify Indemnitee as to Indemnified Costs with respect to any Proceeding to the full extent permitted by any applicable portion of this Agreement that shall not have been invalidated.

to Jurisdiction. This Agreement shall be construed as a whole and in accordance with its fair meaning. Headings are for convenience only and shall not be used in construing meaning. This Agreement shall be
governed and interpreted in accordance with the laws of the State of Delaware applicable to agreements made and to be performed entirely in such State. The Company and the Indemnitee each hereby irrevocably and unconditionally (a) agree that
any action or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court and not in any other state or federal court (other than any appeal from a decision of the Delaware Court), and (b) consent
to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in connection with this Agreement. 

8.5 Amendments; Waivers; Nature of
Rights. No amendment, waiver, modification, termination or cancellation of this Agreement shall be effective unless in writing signed by the party against whom enforcement is sought. No failure or delay in exercising any right will
be deemed a waiver of such right. The indemnification rights afforded to the Indemnitee by this Agreement are contract rights and may not be diminished, eliminated or otherwise affected by amendments to the Company’s Certificate of
Incorporation, its Bylaws or any other agreement, including, without limitation, any D&O Insurance. Indemnitee agrees that neither the stockholders of the Company, nor any director, officer, employee, representative or agent of the Company,
shall be personally liable for the satisfaction of the Company’s obligations under this Agreement and Indemnitee shall look solely to the assets of the Company for satisfaction of any claims hereunder.

capacity by holding such office. The Company agrees that it shall not adopt any amendment to the Company’s Certificate of Incorporation or By-laws in effect on the date hereof the effect of which would be
