 Exhibit 10.4 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of
[            ], 2019 between Baudax Bio, Inc., a Pennsylvania corporation (the “Company”), and [            ]
(“Indemnitee”). 
 RECITALS 

WHEREAS, the Company’s Board of Directors (the “Board”) has determined that the increased difficulty in attracting and
retaining directors is detrimental to the best interests of the Company’s shareholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses on
behalf of, directors to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; and 

WHEREAS, this Agreement is intended to clarify Indemnitee’s entitlement to the maximum indemnity afforded directors under the
Pennsylvania Business Corporation Law (the “PBCL”) and is a supplement to and in furtherance of the provisions calling for indemnification of directors contained in the bylaws or articles of incorporation of the Company
(collectively and as amended from time to time, the “Charter Documents”) and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder;

 WHEREAS, Indemnitee does not regard the protection available under the Company’s Charter Documents and insurance as adequate in the
present circumstances, and Indemnitee is not willing to serve or continue to serve as a director without adequate protection, and the Company desires Indemnitee to serve in such capacity. 

AGREEMENT 
 NOW,
THEREFORE, in consideration of Indemnitee’s agreement to serve, and to continue his or her service, as a director after the date hereof, the parties hereto agree as follows. 

1.    Indemnity of Indemnitee. The Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest
extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof: 

(a)    Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the
rights of indemnification provided in this Section 1(a) if, by reason of his or her Corporate Status (as hereinafter defined), Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as
hereinafter defined) other than a Proceeding by or in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and
amounts paid in settlement actually and reasonably incurred by the Indemnitee, or on his or her behalf, in connection with such Proceeding or any claim, issue or matter therein, 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 reasonable cause to believe the Indemnitee’s conduct was unlawful. 












 (b)    Proceedings by or in the Right of the Company. Indemnitee
shall be entitled to the rights of indemnification provided in this Section 1(b) if, by reason of his or her Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding
brought by or in the right of the Company. Pursuant to this Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in
connection with such Proceeding 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, if applicable law so provides, no
indemnification against such Expenses shall be made in respect of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that a court of competent
jurisdiction of the Commonwealth of Pennsylvania shall determine that such indemnification may be made. 

(c)    Indemnification for Expenses of a Party Who is Wholly or Partly Successful. Notwithstanding any other
provision of this Agreement, to the extent that Indemnitee is, by reason of his or her Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, Indemnitee shall be indemnified to the maximum extent permitted by
law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful,
on the merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf
in connection with each successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to
be a successful result as to such claim, issue or matter. 
 2.    Additional Indemnity. In addition to, and
without regard to any limitations on, the indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties,
fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on his or her behalf if, by reason of his Corporate Status, Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (including a
Proceeding by or in the right of the Company), including, without limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations
pursuant to this Agreement shall be that the Company shall not be obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to
be unlawful. 
 3.    Contribution. 

(a)    Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any
Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or
proceeding without requiring Indemnitee to contribute to such payment, and the Company hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any action, suit or
proceeding in which the 

  
 -2- 













 
Company is jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims asserted against
Indemnitee. 
 (b)    Without diminishing or impairing the obligations of the Company set forth in
Section 3(a), if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined
in such Proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in proportion to the relative benefits received by the
Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, from the
transaction or events from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary to conform to law, be further adjusted by reference to the
relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the
other hand, in connection with the transaction or events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which applicable law may require to be considered. The relative fault of
the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one hand, and Indemnitee, on the other hand, shall
be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary or secondary and the degree to which their conduct is
active or passive. 
 (c)    The Company hereby agrees to fully indemnify and hold Indemnitee harmless from any claims
of contribution which may be brought by officers, directors or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 

(d)    To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is
unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in
settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect
(i) the relative benefits received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault of the Company (and its directors, officers, employees and
agents) and Indemnitee in connection with such event(s) and/or transaction(s). 
 4.    Indemnification for Expenses
of a Witness. Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his or her Corporate Status, a witness, or is made (or asked to) respond to discovery requests, in any Proceeding to which
Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

  
 -3- 













 5.    Advancement of Expenses. Notwithstanding any other
provision of this Agreement, the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after the receipt by the
Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred
by Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that Indemnitee is not entitled to be indemnified against such
Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. 

6.    Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this
Agreement to secure for Indemnitee rights of indemnity that are as favorable as may be permitted under the PBCL and public policy of the Commonwealth of Pennsylvania. Accordingly, the parties agree that the following procedures and presumptions
shall apply in the event of any question as to whether Indemnitee is entitled to indemnification under this Agreement: 

(a)    To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including
therein or therewith 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. The Secretary of the Company shall,
promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of Indemnitee to provide such a request to the Company, or to provide
such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless and only to the extent such failure actually and materially prejudices the interests of the Company. 

(b)    Upon written request by Indemnitee for indemnification pursuant to the first sentence of
Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board: (i) by a
majority vote of the Disinterested Directors (as defined in Section 13 below), even though less than a quorum; (ii) by a committee of Disinterested Directors designated by a majority vote of the Disinterested
Directors, even though less than a quorum; (iii) by Independent Counsel (as defined in Section 13 below) in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee, if (A) there are no
Disinterested Directors or if the Disinterested Directors so direct, or (B) a Change of Control (as hereinafter defined) shall have occurred and Indemnitee so requests; or (iv) if so directed by the Board, by the shareholders of the
Company. 
 (c)    If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant
to Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board, but shall only be an Independent Counsel
to which Indemnitee does not properly object in accordance with the subsequent provisions of this Section 6(c); provided, however, that if a Change of Control shall have occurred, Indemnitee shall select such Independent
Counsel, but only an Independent Counsel to which the Board does not properly object in accordance with the subsequent provisions of this Section 6(c). Within ten (10) days after such written notice of selection shall
have been given, the non-selecting party shall deliver to the selecting party, 

  
 -4- 













 
as the case may be, 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 Section 13 of this Agreement, 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 made and substantiated, the Independent Counsel selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that
such objection is without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to Section 6(a) hereof, no Independent Counsel shall have been selected and
not objected to, either the Company or Indemnitee may petition any court of competent jurisdiction in the Commonwealth of Pennsylvania for resolution of any objection which shall have been made to the selection of Independent Counsel and/or for the
appointment as Independent Counsel of a person selected by the court or by such other person as the 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 6(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to
Section 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this Section 6(c), regardless of the manner in which such Independent Counsel was
selected or appointed. 
 (d)    For purposes of this Section 6, “Change of
Control” means a change in control of the Company of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A promulgated under the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), whether or not the corporation is then subject to such reporting requirement; provided that, without limitation, such a change in control shall be deemed to have occurred if (i) any “person” (as such
term is used in Sections 13(d) and 14(d) of the Exchange Act) is or becomes the “beneficial owner” (as defined in Rule l3d-3 under the Exchange Act), directly or indirectly, of securities of the
Company representing twenty-five percent (25%) or more of the combined voting power of the Company’s then outstanding securities without the prior approval of at least a majority of the members of the Board in office immediately prior to such
acquisition (other than any person (together with its affiliates) who is the beneficial owner of twenty-five percent (25%) or more of the combined voting power of the Company’s outstanding securities as of the date here); and (ii) the
Company is a party to a merger, consolidation, sale of assets or other reorganization, or a proxy contest, as a consequence of which members of the Board in office immediately prior to such transaction or event constitute less than a majority of the
Board thereafter. 
 (e)    In making a determination with respect to entitlement to indemnification hereunder, the
person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear
and convincing evidence. Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is proper in
the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or independent legal counsel) that Indemnitee has not met such applicable standard of conduct,
shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

  
 -5- 













 (f)    Indemnitee shall be deemed to have acted in good faith if
Indemnitee’s action is based on the records or books of account of the Enterprise (as defined in Section 13 below), including financial statements, or on information supplied to Indemnitee by the officers of the
Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert
selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to
indemnification under this Agreement. Whether or not the foregoing provisions of this Section 6(f) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner
Indemnitee reasonably believed to be in or not opposed to the best interests of the Company. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(g)    If the person, persons or entity empowered or selected under Section 6 to determine
whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall be deemed to
have been made and Indemnitee shall be entitled to such indemnification absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in
connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law; provided, however, that such sixty (60)-day period may be extended for a reasonable
time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification in good faith requires such additional time to obtain or evaluate documentation and/or
information relating thereto; and provided, further, that the foregoing provisions of this Section 6(g) shall not apply if the determination of entitlement to indemnification is to be made by the shareholders pursuant to
Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board or the Disinterested Directors, if appropriate, resolve to submit
such determination to the shareholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat, or (B) a special meeting of shareholders is
called within fifteen (15) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is made thereat. 

(h)    Indemnitee shall cooperate with the person, persons or entity making such determination with respect to
Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and which is
reasonably available to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board or shareholder of the Company shall act reasonably and in good faith in making a determination regarding the
Indemnitee’s entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination
shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

  
 -6- 













 (i)    The Company acknowledges that a settlement or other disposition
short of final judgment may be successful if it permits a party to avoid expense, delay, distraction, disruption and uncertainty. In the event that any Proceeding to which Indemnitee is a party is resolved in any manner other than by adverse
judgment against Indemnitee (including, without limitation, settlement of such Proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action,
suit or proceeding. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 

(j)    The termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or
conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did
not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was
unlawful. 
 7.    Remedies of Indemnitee. 

(a)    In the event that (i) a determination is made pursuant to Section 6 of this Agreement
that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to
indemnification is made pursuant to Section 6(b) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to
this Agreement within ten (10) days after receipt by the Company of a written request therefor or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled to
indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the Commonwealth of Pennsylvania, or in
any other court of competent jurisdiction of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within one hundred eighty (180) days following the date on which Indemnitee
first has the right to commence such proceeding pursuant to this Section 7(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication. 

(b)    In the event that a determination shall have been made pursuant to Section 6(b) of this
Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial on the merits and Indemnitee shall not be
prejudiced by reason of the adverse determination under Section 6(b). 
 (c)    If a
determination shall have been made pursuant to Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to
this Section 7, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the
application for indemnification, or (ii) a prohibition of such indemnification under applicable law. 
 (d)    In
the event that Indemnitee, pursuant to this Section 7, seeks a judicial adjudication of Indemnitee’s rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and
officers’ liability insurance policies maintained by the 

  
 -7- 













 
Company, the Company shall pay on Indemnitee’s behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 13 of this
Agreement) actually and reasonably incurred by Indemnitee in such judicial adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery. 

(e)    The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this
Section 7 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. The Company
shall indemnify Indemnitee against any and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to
Indemnitee, which are incurred by Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance
policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

(f)    Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification
under this Agreement shall be required to be made prior to the final disposition of the Proceeding 
 8.    Non-Exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation. 

(a)    The rights of indemnification as provided by this Agreement shall not be deemed exclusive of any other rights to
which Indemnitee may at any time be entitled under applicable law, the Charter Documents, any agreement, a vote of shareholders, a resolution of directors or otherwise, of the Company. No amendment, alteration or repeal of this Agreement or of any
provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his or her Corporate Status prior to such amendment, alteration or repeal. To the extent that a
change in the PBCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Charter Documents and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and
remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy.

 (b)    To the extent that the Company maintains an insurance policy or policies providing liability insurance for
directors, officers, employees, or agents or fiduciaries of the Company or of any other Enterprise that such person serves at the request of the Company, 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 director, officer, employee, agent or fiduciary under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has directors’
and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies. The Company 

  
 -8- 













 
shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms
of such policies. 
 (c)    In the event of any payment under this Agreement, the Company shall be subrogated to the
extent of such payment to all of the rights of recovery of Indemnitee, and the Indemnitee shall execute 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. 
 (d)    The Company shall not be liable under this Agreement to make any
payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise. 

(e)    The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the
request of the Company as a director, officer, employee or agent of any other Enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such other Enterprise (the “Primary
Indemnitor”). Any indemnification or advancement of Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other Enterprise shall only be in excess of, and shall be
secondary to, the indemnification or advancement of Expenses available from the applicable Primary Indemnitor(s) and any applicable insurance policies. 

9.    Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not
be obligated under this Agreement to make any indemnity in connection with any claim made against Indemnitee: 

(a)    for which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity
provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision; 

(b)    for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of
the Company within the meaning of Section 16(b) of the Exchange Act, or similar provisions of state statutory law or common law; or 

(c)    except with respect to a Proceeding relating to enforcement of, or to indemnity under, this Agreement, the Charter
Documents, the PBCL or any insurance policy relating to Indemnitee’s Corporate Status, in connection with any Proceeding (or any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated
by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board authorized the Proceeding (or any part of any Proceeding) prior to its initiation or (ii) the Company provides the
indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law; provided that this prohibition shall not apply to a counterclaim, cross-claim or third party claim brought in any Proceeding. 

10.    Duration of Agreement. All agreements and obligations of the Company contained herein shall continue during
the period Indemnitee is a director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of the 

  
 -9- 













 
Company or another Enterprise) and for a period of ten (10) years thereafter, and shall continue thereafter so long as Indemnitee shall be subject to any Proceeding (or any proceeding
commenced under Section 7 hereof) by reason of Indemnitee’s Corporate Status, whether or not Indemnitee is acting or serving in any such capacity at the time any liability or expense is incurred for which
indemnification can be provided under this Agreement and regardless of any subsequent amendment to the Charter Documents, the PBCL or any other agreement relating to indemnification of Indemnitee. This Agreement shall be binding upon and inure to
the benefit of and be enforceable by the parties hereto and their respective successors (including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the
Company), assigns, spouses, heirs, executors and personal and legal representatives. 
 11.    Security. To the
extent requested by Indemnitee and approved by the Board, the Company may at any time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other
collateral. Any such security, once provided to Indemnitee, may not be revoked or released without the prior written consent of the Indemnitee. 

12.    Enforcement. 

(a)    The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations
imposed on it hereby in order to induce Indemnitee to serve as a director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director of the Company. 

(b)    This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter
hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 

13.    Definitions. For purposes of this Agreement: 

(a)    “Corporate Status” describes the status of a person who is or was a director, officer, employee,
agent or fiduciary of the Company or of any other Enterprise that such person is or was serving at the express written request of the Company. 

(b)    “Disinterested Director” means a director of the Company who is not and was not a party to the
Proceeding in respect of which indemnification is sought by Indemnitee. 
 (c)    “Enterprise” shall
mean the Company and any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that Indemnitee is or was serving at the express written request of the Company as a director, officer, employee, agent or
fiduciary. 
 (d)    “Expenses” shall include all reasonable attorneys’ fees, retainers, court
costs, transcript costs, fees of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and all other disbursements or expenses of the types customarily incurred in
connection with prosecuting, defending, preparing to prosecute or defend, investigating, participating, or being or preparing to be a witness in a Proceeding, or responding to, or objecting to, a request to provide discovery in any

Proceeding. Expenses also shall include Expenses incurred in connection with any appeal resulting from any Proceeding and any federal, state, local or foreign taxes imposed on the Indemnitee as a
result of the actual or deemed receipt of any payments under this Agreement, including without limitation the premium, security for, and other costs relating to any cost bond, supersede as bond, or other appeal bond or its equivalent. Expenses,
however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee. 

(e)    “Independent Counsel” means a law firm, or a member of a law firm, that is experienced in matters
of corporation law and neither presently is, nor in the past five years has been, retained to represent: (i) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under
this Agreement, or of other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent
Counsel” shall not include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s
rights under this Agreement. The Company agrees to pay the reasonable fees of the Independent Counsel referred to above and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to
this Agreement or its engagement pursuant hereto. 
 (f)    “Proceeding” includes any threatened,
pending or completed action, suit, arbitration, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or any other actual, threatened or completed proceeding, whether brought by or in the right of the Company or
otherwise and whether civil, criminal, administrative or investigative, in which Indemnitee was, is or will be involved as a party or otherwise, by reason of the fact that Indemnitee is or was a director of the Company, by reason of any action taken
by Indemnitee or of any inaction on Indemnitee’s part while acting as a director of the Company, or by reason of the fact that Indemnitee is or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of
another Enterprise; in each case whether or not Indemnitee is acting or serving in any such capacity at the time any liability or expense is incurred for which indemnification can be provided under this Agreement; including one pending on or before
the date of this Agreement, but excluding one initiated by an Indemnitee pursuant to Section 7 of this Agreement to enforce his rights under this Agreement. 

14.    Severability. The invalidity or unenforceability of any provision hereof shall in no way affect the validity
or enforceability of any other provision. Further, the invalidity or unenforceability of any provision hereof as to Indemnitee shall in no way affect the validity or enforceability of any provision hereof as to the other. Without limiting the
generality of the foregoing, this Agreement is intended to confer upon Indemnitee indemnification rights to the fullest extent permitted by applicable laws. In the event any provision hereof conflicts with any applicable law, such provision shall be
deemed modified, consistent with the aforementioned intent, to the extent necessary to resolve such conflict. 

15.    Modification and Waiver. No supplement, modification, termination or amendment of this Agreement shall be
binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions hereof (whether or not similar) nor shall such waiver
constitute a continuing waiver.

 16.    Notice By Indemnitee. Indemnitee agrees promptly to notify
the Company in writing upon being served with or otherwise receiving any summons, citation, subpoena, complaint, indictment, information or other document relating to any Proceeding or matter which may be subject to indemnification covered
hereunder. The failure to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise unless and only to the extent that such failure or delay actually materially prejudices
the Company. 
 17.    Notices. All notices and other communications given or made pursuant to this Agreement
shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by confirmed electronic mail or facsimile if sent during normal business hours of the recipient, and if not so
