Form of Neuromed Pharmaceuticals Inc. Indemnification Agreement

 Exhibit 10.55 
 INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement (this “Agreement”) is
entered into as of                     , 2008 by and between Neuromed Pharmaceuticals Inc., a Delaware corporation (the
“Company”), and the director or officer of the Company identified on the signature page hereto (the “Indemnitee”). 
 RECITALS 
 A. The Company and Indemnitee recognize that highly competent persons have become more reluctant to serve
corporations as directors or in other capacities unless they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and
activities on behalf of the corporation. 
 B. The Company and Indemnitee further recognize the substantial increase in corporate litigation
in general, subjecting directors to expensive litigation risks at the same time as the availability and coverage of liability insurance has been severely limited. 
 C. The current protection available to directors and officers may not be adequate under the present circumstances, and directors and officers, including the Indemnitee, may not be willing to continue to serve or be
associated with the Company in such capacities without additional protection for themselves. 
 D. The Company (i) desires to attract
and retain the involvement of highly qualified persons, such as Indemnitee, to serve and be associated with the Company, and (ii) accordingly, wishes to provide for the indemnification and advancement of expenses to the Indemnitee. 

AGREEMENT 
 NOW, THEREFORE, the
Company and the Indemnitee hereby agree as follows: 
 1. Indemnification. 
 (a) Indemnification of Expenses. The Company shall indemnify and hold harmless the Indemnitee to the fullest extent permitted by law if such
Indemnitee was or is or becomes a party to or witness or other participant in, or is threatened to be made a party to or witness or other participant in, any threatened, pending or completed action, suit, proceeding or alternative dispute resolution
mechanism, or any hearing, inquiry or investigation that such Indemnitee in good faith believes might lead to the institution of any such action, suit, proceeding or alternative dispute resolution mechanism, whether civil, criminal, administrative,
investigative or other (hereinafter a “Claim”) by reason of (or arising in part out of) any event or occurrence related to the fact that Indemnitee is or was (or is alleged to be or to have been) a director, officer, employee,
controlling person, fiduciary or other agent or affiliate of the Company, or any subsidiary of the Company, or is or was (or is alleged to be or to have been) serving at the request of the Company as a director, officer, employee, fiduciary or other
agent or affiliate of another corporation, partnership, joint venture, trust or other enterprise, or by reason 

 
of any action or inaction on the part of such Indemnitee while serving or acting (or allegedly serving or acting) in such capacity, including, without
limitation, any such Claim under the Securities Act of 1933, as amended (the “Securities Act”), the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or any other federal or state statutory law or
regulation, or any such Claim, at common law or otherwise, that relates directly or indirectly (i) to the registration, purchase, sale or ownership of any securities of the Company or (ii) to any fiduciary obligation owed with respect to
the Company and its stockholders (hereinafter an “Indemnification Event”), against any and all losses, claims, damages, expenses and liabilities, joint or several, incurred in connection with such Claim (including any investigation,
legal and other expenses incurred in connection with, and any amount paid in settlement of (if such settlement is approved in advance by the Company, which approval shall not be unreasonably withheld) any such Claim) and against any and all expenses
(including reasonable attorneys’ fees and all other costs, expenses and obligations incurred in connection with investigating, defending or participating in (including on appeal), or preparing to defend, be a witness in or participate in, any
action, suit, proceeding, alternative dispute resolution mechanism, hearing, inquiry or investigation related to such Claim), judgments, fines, penalties and amounts paid in settlement (if such settlement is approved in advance by the Company, which
approval shall not be unreasonably withheld) of such Claim and any federal, state, local or foreign taxes imposed on Indemnitee as a result of the actual or deemed receipt of any payments under this Agreement (collectively, hereinafter
“Expenses”), including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses. The Company shall make such payment of Expenses as soon as practicable but in any event no later
than thirty (30) days after written demand by the Indemnitee therefor is presented to the Company. 
 (b) Reviewing Party.
Notwithstanding the foregoing, (i) the obligations of the Company under Section l(a) shall be subject to the condition that the Reviewing Party (as defined in Section 9(e) hereof) shall not have determined (in a written
opinion, in any case in which the Independent Legal Counsel referred to in Section 9(d) hereof is involved) that Indemnitee would not be permitted to be indemnified under applicable law, and (ii) the obligation of the Company to
make an advance payment of Expenses to Indemnitee pursuant to Section 2(a) (an “Expense Advance”) shall be subject to the condition that, if, when and to the extent that a court of competent jurisdiction determines that
Indemnitee would not be permitted to be so indemnified under applicable law, the Company shall be entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the Company if such determination is so made) for all such amounts theretofore
paid. Indemnitee’s obligation to reimburse the Company for any Expense Advance shall be unsecured and no interest shall be charged thereon. If there has not been a Change in Control (as defined in Section 9(c) hereof), the Reviewing
Party shall be selected by the Board of Directors, and if there has been such a Change in Control (other than a Change in Control (i) which has been approved by a majority of the Company’s Board of Directors prior to such Change in Control
or (ii) following which a majority of the Board of Directors of the Company (or the ultimate parent entity thereof) is comprised of directors who were directors of the Company immediately prior to the Change in Control), the Reviewing Party
shall be the Independent Legal Counsel referred to in Section 9(d) hereof subject to the approval of the Indemnitee (which approval shall not be unreasonably withheld). Such counsel, among other things, shall render its written opinion
to the Company and Indemnitee as to whether and to what extent Indemnitee would be permitted to be indemnified under applicable law. The Company agrees to pay the reasonable fees of the Independent Legal Counsel referred to above 

  

 -2- 

 
and to fully indemnify such counsel against any and all expenses (including reasonable attorneys’ fees), claims, liabilities and damages arising out of
or relating to this Agreement or its engagement pursuant hereto. If there has been no determination by the Reviewing Party or if the Reviewing Party determines that Indemnitee substantively would not be permitted to be indemnified in whole or in
part under applicable law, Indemnitee shall have the right to commence litigation seeking an initial determination by the court or challenging any such determination by the Reviewing Party or any aspect thereof, including the legal or factual bases
therefor, and the Company hereby consents to service of process and to appear in any such proceeding. Any determination by the Reviewing Party otherwise shall be conclusive and binding on the Company and Indemnitee. 
 (c) Contribution. If the indemnification provided for in Section 1(a) above for any reason is held by a court of competent
jurisdiction to be unavailable to Indemnitee in respect of any Claims referred to therein, then the Company, in lieu of indemnifying Indemnitee thereunder, shall contribute to the amount paid or payable by Indemnitee as a result of such losses,
claims, damages, expenses or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Indemnitee, or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company and the Indemnitee in connection with the action or inaction which
resulted in such losses, claims, damages, expenses or liabilities, as well as any other relevant equitable considerations. 
 (d) Survival
Regardless of Investigation. The indemnification and contribution provided for in this Section 1 will remain in full force and effect regardless of any investigation made by or on behalf of the Indemnitee or any officer, director,
employee, agent or controlling person of the Indemnitee. 
 (e) Mandatory Payment of Expenses. Notwithstanding any other provision of
this Agreement, to the extent that an Indemnitee has been successful on the merits or otherwise, including, without limitation, the dismissal of an action without prejudice, in the defense of any action, suit, proceeding, inquiry or investigation
referred to in Section (l)(a) hereof or in the defense of any claim, issue or matter therein, such Indemnitee shall be indemnified against all Expenses incurred by such Indemnitee in connection therewith. 
 2. Expenses; Indemnification Procedure. 
 (a) Advancement of Expenses. The Company shall advance all Expenses incurred by any Indemnitee. The advances to be made hereunder shall be paid by the Company to the Indemnitee as soon as practicable but in any event no later than
thirty (30) days after written demand by such Indemnitee therefor to the Company, which written demand shall include reasonable detail and support for the amount of the Expenses to be so advanced. 
 (b) Notice/Cooperation by Indemnitees. Indemnitee shall, as a condition precedent to Indemnitee’s right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any Claim made against Indemnitee for which indemnification will or could be sought under this Agreement. In addition, Indemnitee shall give the Company such information and
cooperation as it may reasonably require and as shall be within Indemnitee’s power. 
  

 -3- 

 (c) No Presumptions; Burden of Proof. For purposes of this Agreement, the termination of any Claim
by judgment, order, settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere, or its equivalent, shall not 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. In addition, neither the failure of the Reviewing Party to have made a determination as to whether an Indemnitee has met any
particular standard of conduct or had any particular belief, nor an actual determination by the Reviewing Party that the Indemnitee has not met such standard of conduct or did not have such belief, prior to the commencement of legal proceedings by
Indemnitee to secure a judicial determination that the Indemnitee should be indemnified under applicable law, shall be a defense to the Indemnitee’s claim or create a presumption that the Indemnitee has not met any particular standard of
conduct or did not have any particular belief. In connection with any determination by the Reviewing Party or otherwise as to whether the Indemnitee is entitled to be indemnified hereunder, the burden of proof shall be on the Company to establish
that the Indemnitee is not so entitled. 
 (d) Notice to Insurers. If, at the time of the receipt by the Company of a notice of a
Claim pursuant to Section 2(b) hereof, the Company has liability insurance in effect which may cover such Claim, the Company shall give prompt notice of the commencement of such Claim to the insurers in accordance with the procedures set
forth in the respective policies. If the Company has not paid such amounts directly, the Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of each Indemnitee, all amounts payable as a result of
such action, suit, proceeding, inquiry or investigation in accordance with the terms of such policies. 
 (e) Selection of Counsel. In
the event the Company shall be obligated hereunder to pay the Expenses of any Claim, the Company shall be entitled to assume the defense of such Claim, with counsel approved by the applicable Indemnitee, which approval shall not be unreasonably
withheld, upon the delivery to such Indemnitee of written notice of its election to do so. After delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to
Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same Claim; provided, however, that (i) Indemnitee shall have the right to employ Indemnitee’s separate counsel in any such
Claim at Indemnitee’s expense and (ii) if (A) the employment of separate counsel by Indemnitee has been previously authorized by the Company, (B) Indemnitee shall have reasonably concluded that there may be a conflict of interest
between the Company and Indemnitee in the conduct of any such defense, or (C) the Company shall not continue to retain such counsel to defend such Claim, then the fees and expenses of Indemnitee’s separate counsel shall be at the expense
of the Company. As long as the Company has otherwise complied with the terms hereof, the Company shall have the right to conduct such defense as it sees fit in its sole discretion, including the right to settle any claim, action or proceeding
against any Indemnitee without the consent of such Indemnitee, provided such settlement includes a full release of the Indemnitee by the claimant from all liabilities or potential liabilities under such Claim. 
  

 -4- 

 3. Additional Indemnification Rights: Nonexclusivity. 
 (a) Scope. The Company hereby agrees to indemnify Indemnitee to the fullest extent permitted by law and in accordance with the terms hereof,
notwithstanding that such indemnification may not be specifically authorized by the Company’s certificate of incorporation, the Company’s bylaws or by statute. In the event of any change after the date of this Agreement in any applicable
law, statute or rule which expands the right of a Delaware corporation to indemnify a member of its Board of Directors or an officer, employee, agent or fiduciary, the Indemnitee shall enjoy by this Agreement the greater benefits afforded by such
change. In the event of any change in any applicable law, statute or rule which narrows the right of a Delaware corporation to indemnify a member of its Board of Directors or an officer, employee, agent or fiduciary, such change, to the extent not
otherwise required by such law, statute or rule to be applied to this Agreement, shall have no effect on this Agreement or the parties’ rights and obligations hereunder except as set forth in Section 8(a) hereof. 
 (b) Nonexclusivity. The indemnification provided by this Agreement shall be in addition to any rights to which Indemnitee may be entitled under
the Company’s certificate of incorporation, its bylaws, any agreement, any vote of stockholders or disinterested directors, the Delaware General Corporation Law, or otherwise. The indemnification provided under this Agreement shall continue for
any action that Indemnitee took or did not take while serving in an indemnified capacity even though Indemnitee may have ceased to serve in such capacity. 
 4. No Duplication of Payments. The Company shall not be liable under this Agreement to make any payment in connection with any Claim made against Indemnitee to the extent Indemnitee has otherwise actually
received payment (under any insurance policy, the Company’s certificate of incorporation, its bylaws or otherwise) of the amounts otherwise indemnifiable hereunder. 
 5. Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for any portion of Expenses incurred in connection with any Claim, but not, however,
for all of the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion of such Expenses to which such Indemnitee is entitled. 
 6. Mutual Acknowledgment. The Company and Indemnitee acknowledge that in certain instances, federal law or applicable public policy may prohibit the Company from indemnifying its directors, controlling persons,
fiduciaries or other agents or affiliates under this Agreement or otherwise. Indemnitee understands, acknowledges and agrees that the Company has undertaken or may be required in the future to undertake with the Securities and Exchange Commission to
submit the question of indemnification to a court in certain circumstances for a determination of the Company’s rights under public policy to indemnify Indemnitee, notwithstanding any provision hereof to the contrary. 
 7. Liability Insurance. The Company shall, from time to time, make a good faith determination as to whether or not it is practicable for the
Company to obtain and maintain a policy or policies with reputable insurance companies covering certain liabilities that may be incurred by its directors, officers, employees, control persons, fiduciaries or other agents and 

  

 -5- 

 
affiliates. Notwithstanding the foregoing, the Company shall have no obligation to obtain or maintain such insurance if the Company determines in good faith
that such insurance is not reasonably available, if the premium costs for such insurance are disproportionate to the amount of coverage provided, if the coverage provide by such insurance is limited by exclusions so as to provide an insufficient
benefit, or if the Indemnitee is covered by similar insurance maintained by a parent or subsidiary of the Company. To the extent the Company maintains liability insurance applicable to directors, officers, employees, control persons, fiduciaries or
other agents and affiliates, such Indemnitee shall be covered by such policies in such a manner as to provide to such Indemnitee the same rights and benefits as are accorded to the most favorably insured of the Company’s directors, if such
Indemnitee is a director, or of the Company’s officers, if such Indemnitee is not a director of the Company but is an officer. 
 8.
Exceptions. Any other provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of this Agreement: 
 (a) Excluded Action or Omissions. To indemnify Indemnitee for any intentional malfeasance by the Indemnitee or any act undertaken by the Indemnitee where the Indemnitee did not in good faith believe the
Indemnitee was acting in the best interests of the Company, or for any other acts, omissions or transactions from which the Indemnitee may not be relieved of liability under applicable law, in each case, as determined by a court of competent
jurisdiction; 
 (b) Claims Initiated by Indemnitee. To indemnify or advance expenses to any Indemnitee with respect to Claims
initiated or brought voluntarily by such Indemnitee and not by way of defense, except (i) with respect to actions or proceedings to establish or enforce a right to indemnity under this Agreement or any other agreement or insurance policy or
under the Company’s certificate of incorporation or bylaws now or hereafter in effect relating to Claims for Indemnification Events, (ii) in specific cases if the Board of Directors has approved the initiation or bringing of such Claim, or
(iii) as otherwise required under the Delaware General Corporation Law, regardless of whether such Indemnitee ultimately is determined to be entitled to such indemnification, advance expense payment or insurance recovery, as the case may be;

 (c) Lack of Good Faith. To indemnify any Indemnitee for any expenses incurred by such Indemnitee with respect to any proceeding
instituted by Indemnitee to enforce or interpret this Agreement, if a court of competent jurisdiction determines that each of the material assertions made by the Indemnitee in such proceeding was not made in good faith or was frivolous; or

 (d) Claims Under Section 16(b). To indemnify Indemnitee for expenses and the payment of profits arising from the purchase and
sale by Indemnitee of securities in violation of Section 16(b) of the Exchange Act or any similar successor statute as determined by a court of competent jurisdiction. 
 9. Construction of Certain Phrases. 
 (a) For purposes of this Agreement, references to the “Company” shall include, in addition to the resulting corporation, any constituent corporation (including any 

  

 -6- 

 
constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to
indemnify its directors, officers, employees, agents, and fiduciaries, so that if Indemnitee is or was a director, officer, employee, agent, control person, or fiduciary of such constituent corporation, or is or was serving at the request of such
constituent corporation as a director, officer, employee, control person, agent or fiduciary or another corporation, partnership, joint venture, employee benefit plan, trust or other enterprise, such Indemnitee shall stand in the same position under
the provisions of this Agreement with respect to the resulting or surviving corporation as such Indemnitee would have with respect to such constituent corporation if its separate existence had continued. 
 (b) For purposes of this Agreement, references to “other enterprises” shall include employee benefit plans; references to
“fines” shall include any excise taxes assessed on any Indemnitee with respect to an employee benefit plan; and references to “serving at the request of the Company” shall include any service as a director, office,
employee, agent or fiduciary of the Company which imposes duties on, or involves services by, such director, officer, employee, agent or fiduciary with respect to an employee benefit plan, its participants or its beneficiaries; and if any Indemnitee
acted in good faith and in a manner such Indemnitee reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan, such Indemnitee shall be deemed to have acted in a manner “not opposed to the
best interests of the Company” as referred to in this Agreement. 
 (c) For purposes of this Agreement a “Change in
Control” shall have the meaning set forth in the Company’s certificate of incorporation. 
 (d) For purposes of this Agreement,
“Independent Legal Counsel” shall mean an attorney or firm of attorneys, selected in accordance with the provisions of Section l(b) hereof, who shall not have otherwise performed services for the Company or any Indemnitee
within the last three years (other than with respect to matters concerning the right of any Indemnitee under this Agreement, or of other indemnitees under similar indemnity agreements). 
 (e) For purposes of this Agreement, a “Reviewing Party” shall mean any appropriate person or body consisting of a member or members of
the Company’s Board of Directors or any other person or body appointed by the Board of Directors who is not a party to the particular Claim for which an Indemnitee is seeking indemnification, or Independent Legal Counsel. 
 (f) For purposes of this Agreement, “Voting Securities” shall mean any securities of the Company that vote generally in the election of
directors. 
 10. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall constitute an
original. 
 11. Binding Effect; Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of and be
enforceable by the parties hereto and their respective successors, assigns, including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business and/or assets of the Company (and the
Company may assign its rights and obligations under this Agreement in connection with any 

  

 -7- 

 
such transaction without the consent of Indemnitee), spouses, heirs, and personal and legal representatives. The Company shall require and cause any
successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all, substantially all, or a substantial part, of the business and/or assets of the Company, by written agreement in form and substance satisfactory to
Indemnitee, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. This Agreement shall continue in effect with respect
to Claims relating to Indemnification Events regardless of whether Indemnitee continues to serve as a director, officer, employee, agent, controlling person, or fiduciary of the Company or of any other enterprise at the Company’s request.

 12. Attorneys’ Fees. In the event that any action is instituted by an Indemnitee under this Agreement or under any liability
insurance policies maintained by the Company to enforce or interpret any of the terms hereof or thereof, Indemnitee shall be entitled to be paid all expenses (including reasonable attorneys’ fees and all other costs, expenses and obligations
incurred in connection with investigating, defending or participating in (including on appeal), or preparing to defend, be a witness in or participate in, any such action) incurred by Indemnitee with respect to such action, regardless of whether
such Indemnitee is ultimately successful in such action, unless, as part of such action, a court of competent jurisdiction determines that each of the material assertions made by Indemnitee as a basis for such action were not made in good faith or
were frivolous. In connection with such action, Indemnitee shall be entitled to the advancement of expenses (including reasonable attorneys’ fees and all other costs, expenses and obligations incurred in connection investigating, defending a
witness in or participating in (including on appeal), or preparing to defend, be a witness in or participate in, any such action) with respect to such action, unless, as a part of such action, a court of competent jurisdiction over such action
determines that each of the material assertions made by such Indemnitee as a basis for such action was not made in good faith or was frivolous. In the event of an action instituted by or in the name of the Company under this Agreement to enforce or
interpret any of the terms of this Agreement, the Indemnitee shall be entitled to be paid all expenses (including reasonable attorneys’ fees and all other costs, expenses and obligations incurred in connection investigating, defending a witness
in or participating in (including on appeal), or preparing to defend, be a witness in or participate in, any such action) incurred by such Indemnitee in defense of such action (including costs and expenses incurred with respect to Indemnitee
counterclaims and cross-claims made in such action), and shall be entitled to the advancement of expenses (including reasonable attorneys’ fees and all other costs, expenses and obligations incurred in connection investigating, defending a
witness in or participating in (including on appeal), or preparing to defend, be a witness in or participate in, any such action) with respect to such action, unless, as a part of such action, a court having jurisdiction over such action determines
that each of such Indemnitee’s material defenses to such action was not made in good faith or was frivolous. 
 13. Notice. All
notices and other communications required or permitted hereunder shall be in writing, shall be effective when given, and shall in any event be deemed to be given (a) five (5) days after deposit with the U.S. Postal Service or other
applicable postal service, if delivered by first class mail, postage prepaid, (b) upon delivery, if delivered by hand, (c) one business day after the business day of deposit with Federal Express or similar overnight courier, freight
prepaid, or (d) one day after the business day of delivery by facsimile transmission, if 

  

 -8- 

 
delivered by facsimile transmission, with copy by first class mail, postage prepaid, and shall be addressed if to Indemnitee, at the Indemnitee address as
set forth beneath Indemnitee signatures to this Agreement and if to the Company at the address of its principal corporate offices (attention: Secretary) or at such other address as such party may designate by ten days’ advance written notice to
the other party hereto. 
 14. Consent to Jurisdiction. The Company and Indemnitee each hereby irrevocably consent to the jurisdiction
of the courts of the State of Delaware for all purposes in connection with any action or proceeding that arises out of or relates to this Agreement and agree that any action instituted under this Agreement shall be commenced, prosecuted and
continued only in the Court of Chancery of the State of Delaware in and for New Castle County, which shall be the exclusive and only proper forum for adjudicating such a claim. 
 15. Severability. The provisions of this Agreement shall be severable in the event that any of the provisions hereof (including any provision
within a single section, paragraph or sentence) are held by a court of competent jurisdiction to be invalid, void or otherwise unenforceable, and the remaining provisions shall remain enforceable to the fullest extent permitted by law. Furthermore,
to the fullest extent possible, the provisions of this Agreement (including, without limitations, each portion of this Agreement containing any provision held to be invalid, void or otherwise unenforceable, that is not itself invalid, void or
unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable. 
 16. Choice of Law. This Agreement shall be governed by and its provisions construed and enforced in accordance with the laws of the State of Delaware, as applied to contracts between Delaware residents, entered into and to be
performed entirely within the State of Delaware, without regard to the conflict of laws principles thereof. 
 17. Subrogation. In the
event of payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee, who shall execute all documents required and shall do all acts that may be necessary to secure such
rights and to enable the Company effectively to bring suit to enforce such rights. 
 18. Amendment and Termination. No amendment,
modification, termination or cancellation of this Agreement shall be effective unless it is in writing signed by the Company and Indemnitee. 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. 
 19. Integration and Entire
Agreement. This Agreement sets forth the entire understanding between the parties hereto and supersedes and merges all previous written and oral negotiations, commitments, understandings and agreements relating to the subject matter hereof
between the parties hereto, including, without limitation, any prior written or oral indemnification agreement between the Indemnitee and the Company. 
 20. Primacy of Indemnification; Subrogation. 
  

 -9- 

 (a) The Company hereby acknowledges that the Indemnitee has certain rights to indemnification and/or
insurance provided by [Name of Fund/Sponsor] and certain of [its][their] affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees that it is the indemnitor of first resort for all amounts payable
hereunder (i.e., its obligations to Indemnitee are primary and those of the Fund Indemnitors are secondary), it shall be liable for the full amount of all amounts payable hereunder (collectively, the “Indemnifiable Amounts”)
to the extent legally permitted and it irrevocably waives any claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the
Fund Indemnitors on behalf of the Indemnitee with respect to any claim for which the Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated
to the extent of such advancement or payment to all of the rights of recovery of the Indemnitee against the Company. The Company and the Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms hereof.

 (b) Except as provided in Section 20(a) above, in the event of any payment of Indemnifiable Amounts under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights of contribution or recovery of the Indemnitee against other persons (other than the Fund Indemnitors), and the Indemnitee shall take, at the request of the Company, all
reasonable action necessary to secure such rights, including the execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

 WHEREAS: 
  

	A.	the Company is a company existing under the laws of the Province of British Columbia; 

  

	B.	the Indemnified Party is an officer and/or director of the Company and is or may become an officer and/or director of another company (an “Affiliate Company”)
either at the request of the Company or at a time when such company is an affiliate of the Company. For the purposes of this Agreement, a company is affiliated with another company if (a) one of them is a subsidiary of the other; (b) both
of them are subsidiaries of the same company; or (c) each of them is controlled by the same person (a company is controlled by a person if that person holds 50% or more of the voting rights attached to all of the outstanding voting securities

 NOW THEREFORE in consideration of the Indemnified Party acting as a director and/or officer of the Company and/or of an Affiliate Company, and for other good and
valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows: 
  

	1.	Agreement to Serve 

  

	1.01	The Indemnified Party agrees to serve or continue to serve as a director or officer of the Company (in the case of an officer of the Company, at the will of the Company or under a

duly elected, appointed or employed and qualified in accordance with the provisions of the Business Corporations Act (British Columbia) (the “Act”) and the Articles of the Company or Affiliate Company as the case may be;
provided, however, that (i) the Indemnified Party may at any time and for any reason resign from such position (subject to any contractual obligations which the Indemnified Party shall have assumed apart from this Agreement), and
(ii) neither the Company nor any Affiliate Company shall have any obligation under this Agreement to continue the Indemnified Party in any such position. 

	2.	Indemnification 

  

	2.01	Subject to subsection 2.03 below and any limitations contained in the Act, the Company covenants and agrees to indemnify and hold harmless the Indemnified Party to the fullest
extent permitted by law, (including but limited to the indemnity under the Act) from and against any and all Losses which the Indemnified Party may reasonably suffer, sustain, incur or be required to pay in respect of any Claim, provided that the
indemnity provided for in this Section 2.01 will only be available if: 

  

	 	(a)	the Indemnified Party was acting honestly and in good faith with a view to the best interests of the Company or Affiliate Company, as the case may be; and 

 

	 	(b)	in the case of an action or proceeding that is not a civil action or proceeding, the Indemnified Party had reasonable grounds for believing that the Indemnified Party’s conduct
in respect of which the action or proceeding in question was brought was lawful. 

 For the purposes of this Agreement,
“proceeding” shall include any civil, criminal, administrative or investigative or other proceeding of any nature or kind in which the Indemnified Party is involved because of the Indemnified Party’s association with the
Company; “Losses” means all costs, charges, expenses, losses, damages, fees (including any legal, professional or advisory fees or disbursements), liabilities, amounts paid to settle or dispose of any Claim or satisfy any judgment,
fines, penalties or liabilities, without limitation, and whether incurred alone or jointly with others, including any amounts which the Indemnified Party may reasonably suffer, sustain, incur or be required to pay in respect of the investigation,
defence, settlement or appeal of or preparation for any Claim or with any action to establish a right to indemnification under this Agreement, and for greater certainty, includes all taxes, interest, penalties and related outlays of the Indemnified
Party arising from any indemnification of the Indemnified Party by the Company pursuant to this Agreement and “Claim” includes any civil, criminal, administrative or investigative or other proceeding of any nature or kind in which
the Indemnified Party is involved because of the Indemnified Party’s association with the Company or an Affiliate Company. 
  

	2.02	Notwithstanding any other provision of this Agreement, the indemnities provided in this Agreement shall apply to the Indemnified Party in respect of facts arising during the time
the Indemnified Party was a director or officer of the Company or of an Affiliate Company of which the Company was then a shareholder and, in respect of such Affiliate Company, the Company had designated the Indemnified Party as its nominee director
or officer. 

  

	2.03	Notwithstanding any other provision herein, but subject to the Act, the Indemnified Party is entitled to an indemnity from the Company in respect of all costs, charges and expenses
reasonably incurred by the Indemnified Party in connection with the defence of any Claim, if the Indemnified Party: 

  

	 	(a)	was not judged by the court or other competent authority to have committed any fault or omitted to do anything that the Indemnified Party ought to have done; and

  

	 	(b)	fulfills the conditions set out in Sections 2.01(a) and (b) above. 

  

	2.04	No indemnification of the Indemnified Party shall be made except to the extent approved by the Court pursuant to the Act or any other statute, if such approval is required pursuant
to such legislation. If such approval is required, the Company shall use all reasonable best efforts to procure such approval. The determination of any action, suit or proceeding by judgment, order, settlement, conviction or otherwise shall not, of
itself, create a presumption that the Indemnified Party did not act honestly and in good faith and in the best interests of the Company or Affiliate Company and, with respect to any action or proceeding that is not a civil action or proceeding, did
not have reasonable grounds to believe that the Indemnified Party’s conduct was lawful. 

  

 -2- 

	2.05	In respect of any action or proceeding by or on behalf of the Company to procure a judgment in its favour against the Indemnified Party, in respect of which the Indemnified Party is
made a party because of the Indemnified Party’s association with the Company, the Company shall make application, at its expense, for the approval of a court of competent jurisdiction to advance monies to the Indemnified Party for costs,
charges and expenses reasonably incurred by the Indemnified Party in connection with such action and to indemnify and save harmless the Indemnified Party for such costs, charges and expenses of such action, provided the Indemnified Party fulfils the
conditions set out in Sections 2.03 and 2.04 above and provided that such indemnification or advance is not prohibited under any applicable statute and provided the Indemnified Party is obligated to repay such funds advanced if the Indemnified Party
ultimately does not fulfil the conditions set out in Sections 2.03 and 2.04 above. 

  

	2.06	No action or proceeding brought or instituted under this Agreement and no recovery pursuant thereto shall be a bar or defence to any further action or proceeding which may be
brought under this Agreement. 

  

	2.07	The provisions of this section 2 shall apply to all actions and proceedings, whether such action or proceeding is in respect of facts arising before or subsequent to the effective
date of this Agreement. 

  

	3.	Payment of Expenses 

  

	3.01	Subject to Section 2.05 of this Agreement, the Company may, at the request of the Indemnified Party, advance to the Indemnified Party sufficient funds, or arrange to pay on
behalf of or reimburse the Indemnified Party for any costs, charges or expenses reasonably incurred by the Indemnified Party in investigating, defending, appealing, preparing for, providing evidence in or instructing and receiving the advice of the
Indemnified Party’s counsel or other professional advisors in regard to any Claim or other matter for which the Indemnified Party may be entitled to an indemnity or reimbursement under this Agreement, and such amounts shall be treated as a
non-interest bearing advance or loan to the Indemnified Party, pending approval of the Company and the Court (if required), to the payment thereof as an indemnity and provided that the Indemnified Party fulfils the conditions set out in Sections
2.01(a) and (b) above. In the event it is ultimately determined by a Court of competent jurisdiction that the Indemnified Party did not fulfill the conditions set out in Sections 2.01 (a) and (b) above, or that the Indemnified Party
was not entitled to be fully so indemnified, such loan or advance, or the appropriate portion thereof shall, upon written notice of such determination being given by the Company to the Indemnified Party detailing the basis for such
determination, be repayable on demand and shall bear interest from the date of such notice at the prime rate prescribed from time to time by the Company’s principal commercial bank. The Company shall not make any payments referred to in this
Section 3.01 unless the Company first receives from the Indemnified Party a written undertaking that, if it is ultimately determined that the payment of expenses is prohibited by the Act, the Indemnified Party will repay the amounts advanced or
reimbursed. 

  

	3.02	In the event that, after the final disposition of an action or proceeding, the Indemnified Party has not been reimbursed or has only been partially reimbursed for expenses actually
and reasonably incurred in respect of an action or proceeding, and the Indemnified Party is wholly successful, on the merits or otherwise, in the outcome of the action or proceeding or is substantially successful on the merits in the outcome of such
action or proceeding, then the Company shall pay to the Indemnified Party an amount equal to the expenses actually and reasonably incurred less the amount, if any, which has been reimbursed. 

  

	4.	Non-Exclusive Indemnification 

  

	4.01	 The indemnification provided by this Agreement shall not exclude any separate rights of indemnification to which the Indemnified Party may otherwise be entitled
under the Articles of the Company, or any valid and lawful agreement, vote of shareholders or disinterested directors or 

  

 -3- 

	 	 
otherwise, both as to action in the Indemnified Party’s official capacity and as to action in another capacity while holding such office, and such
separate rights of indemnification shall continue if the Indemnified Party has ceased to be a director or officer of the Company or Affiliate Company and shall enure to the benefit of the heirs, executors and administrators of the Indemnified Party.

  

	5.	Compliance with the Act 

  

	5.01	To the extent that the terms of this Agreement are contrary to the provisions of the Act, as amended from time to time, or other applicable laws, the terms of this Agreement shall
be deemed to be amended to comply therewith (it being understood that nothing contained herein shall be considered to impose an obligation upon the Company which it is prohibited from complying with by virtue of such legislation).

  

	6.	Notice of Proceedings 

  

	6.01	The Indemnified Party and the Company each agree to give notice to the other in writing as soon as is reasonably practicable after: 

  

	 	(a)	being served with any statement of claim, writ, notice of motion, indictment or other document commencing or continuing any civil, criminal or administrative action or proceeding
naming the Indemnified Party as a party; or 

  

	 	(b)	receiving notice of any such threatened civil, criminal or administrative action or proceeding or alleged wrongdoing against the Indemnified Party, 

 which arises by reason of the Indemnified Party being or having been a director or officer of the Company or Affiliated Company provided, however, that
the failure of the Indemnified Party to give such notice to the Company shall not adversely affect the Indemnified Party’s rights under this Agreement except to the extent that the Company shall have been materially prejudiced as a direct
result of such failure. 
  

	7.	Rights to Retain Other Counsel 

  

	7.01	Upon receipt of notice from the Indemnified Party pursuant to Section 6 above, the Company agrees to promptly retain counsel who shall be reasonably satisfactory to the
Indemnified Party to represent the Indemnified Party in such matter. The Indemnified Party shall have the right to retain other counsel to act on the Indemnified Party’s behalf and the fees and disbursements of such other counsel shall be paid
by the Company if: 

  

	 	(a)	the Indemnified Party and the Company or an Affiliate Company have mutually agreed to the retention of such other counsel; 

  

	 	(b)	the named parties to any such action, claim, demand or proceeding (including any added third, or interpleaded parties) include the Company or an Affiliate Company and the
Indemnified Party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them (including the availability of different defences); or 

  

	 	(c)	the Company has not retained reasonably satisfactory counsel for the Indemnified Party within ten (10) business days of any receipt of notice pursuant to Section 6 above.

  

	8.	Indemnified Party to Cooperate 

  

	8.01	The Indemnified Party agrees to give the Company and any Affiliate Company such information and cooperation as may be reasonably required by same from time to time in respect of all
matters contemplated by this Agreement.

	9.	Notices 

  

	9.01	Any notice, direction, request or other communication required or contemplated by any provision herein will be given in writing and will be given by delivery or faxing same to the
Indemnified Party or the Company, as the case may be, as follows: 

  

	 	(a)	if to the Indemnified Party, at:

change its fax number or address for service from time to time by written notice in accordance with this section. 
 If the Company receives
notice from any other source of any matter which the Indemnified Party would otherwise be obligated hereunder to give notice to the Company, then the Indemnified Party shall be relieved of his obligation hereunder to give notice to the Company,
provided the Company has not suffered any material damage from the failure of the Indemnified Party to give notice as herein required. 
  

	10.	Miscellaneous 

  

	10.01	Each of the covenants and provisions hereof is severable from every other covenant and provision and the invalidity or unenforceability of any one or more covenants and provisions
of this Agreement shall not affect the validity or enforceability of the remaining covenants and provisions hereof. 

  

	10.02	This Agreement shall be binding upon and enure to the benefit of the parties hereto and their respective heirs, administrators, executors, successors and assigns. None of the
parties hereto may assign their rights or obligations under this Agreement without the prior written consent of the other party hereto.

in any bankruptcy, insolvency, receivership or other similar proceeding of creditors. 

  

	10.05	This Agreement constitutes the complete agreement between the parties and with respect to subject matter treated herein and shall not be varied in its terms by oral agreement,
representation or otherwise except an instrument or instruments in writing dated subsequent to the date hereof and executed by the parties, and this Agreement supercedes all prior agreements, memoranda, correspondence, communication, negotiations or
representations, whether oral or written, express or implied, between the parties with respect to the subject matter. For greater certainty, the rights of the Indemnified Party under this Agreement shall not be prejudiced or impaired by permitting
or consenting to any assignment in bankruptcy, receivership, insolvency or any other creditor’s proceedings of or against the Company or by the winding-up or dissolution of the Company. 

  

 -5- 

	10.06	This Agreement was prepared by the solicitors for the Company. The Indemnified Party has been asked to obtain independent legal advice before signing this Agreement and the
Indemnified Party represents, by signing this Agreement that the Indemnified Party has obtained such advice or the Indemnified Party has declined to seek independent legal advice on this Agreement, despite having been given the opportunity to do so.

 IN WITNESS WHEREOF the parties have executed this Agreement.
