Form of Indemnification Agreement for Officers and Directors



 Exhibit 10.5 
 INDEMNIFICATION AGREEMENT 
 This Indemnification Agreement (this
“Agreement”), dated as of             , 20    , is made by and between Luca Technologies Inc., a Delaware corporation (the
“Company”), and                             , a director and/or officer of the
Company (the “Indemnitee”). 
 RECITALS 

A. The Company is aware that competent and experienced persons are increasingly reluctant to serve as directors or officers of
corporations unless they are protected by comprehensive liability insurance and/or indemnification, due to increased exposure to litigation costs and risks resulting from their service to such corporations, and because the exposure frequently bears
no reasonable relationship to the compensation of such directors and officers; 
 B. Based on their experience as business
managers, the Board of Directors of the Company (the “Board”) has concluded that, to retain and attract talented and experienced individuals to serve as officers and directors of the Company, and to encourage such individuals
to take the business risks necessary for the success of the Company, it is necessary for the Company contractually to indemnify officers and directors and to assume for itself maximum liability for expenses and damages in connection with claims
against such officers and directors in connection with their service to the Company; 
 C. Section 145 of the General
Corporation Law of Delaware, under which the Company is organized (the “Law”), empowers the Company to indemnify by agreement its officers, directors, employees and agents, and persons who serve, at the request of the
Company, as directors, officers, employees or agents of other corporations or enterprises, and expressly provides that the indemnification provided by the Law is not exclusive; and 

D. The Company desires and has requested the Indemnitee to serve or continue to serve as a director and/or officer of the Company free
from undue concern for claims for damages arising out of or related to such services to the Company. 
 NOW, THEREFORE,
the parties hereto, intending to be legally bound, hereby agree as follows: 
 1. Definitions. 

1.1 Agent. For the purposes of this Agreement, “agent” of the Company means any person who is or was
a director or officer of the Company or a subsidiary of the Company; or is or was serving at the request of the Company or a subsidiary of the Company as a director or officer of another foreign or domestic corporation, partnership, joint venture,
trust or other enterprise or an affiliate of the Company; or was a director or officer of a foreign or domestic corporation or limited liability company which was a predecessor corporation or limited liability company of the Company or was a
director or officer of another enterprise or affiliate of the Company at the request of such predecessor corporation or limited liability company. The term “enterprise” includes any employee benefit plan of the Company, its
subsidiaries, affiliates and predecessor corporations or limited liability companies. 







 1.2 Expenses. For purposes of this Agreement,
“expenses” includes all direct and indirect costs of any type or nature whatsoever (including, without limitation, all attorneys’ fees and related disbursements and other out-of-pocket costs) actually and reasonably
incurred by the Indemnitee in connection with the investigation, defense or appeal of a proceeding to which the Indemnitee is made a party by reason of the fact that he is or was an agent of the Company or establishing or enforcing a right to
indemnification or advancement of expenses under this Agreement. 
 1.3 Proceeding. For the purposes of this
Agreement, “proceeding” means any threatened, pending or completed action, suit or other proceeding, whether civil, criminal, administrative, investigative or any other type whatsoever. 

1.4 Subsidiary. For purposes of this Agreement, “subsidiary” means any corporation, limited
liability company or other entity of which more than fifty percent (50%) of the outstanding voting securities is owned directly or indirectly by the Company, by the Company and one or more of its subsidiaries or by one or more of the
Company’s subsidiaries. 
 2. Agreement to Serve. The Indemnitee agrees to serve and/or continue to
serve as an agent of the Company, at the will of the Company (or under separate agreement, if such agreement exists), in the capacity the Indemnitee currently serves as an agent of the Company, faithfully and to the best of his ability, so long as
he or she is duly appointed or elected and qualified in accordance with the applicable provisions of the charter documents of the Company or any subsidiary of the Company; provided, however, that the Indemnitee may at any time and for
any reason resign from such position (subject to any contractual obligation that the Indemnitee may have assumed apart from this Agreement), and the Company or any subsidiary shall have no obligation under this Agreement to continue the Indemnitee
in any such position. 
 3. Directors’ and Officers’ Insurance. The Company shall, to the extent
that the Board determines it to be economically reasonable, maintain a policy of directors’ and officers’ liability insurance (“D&O Insurance”), on such terms and conditions as may be approved by the Board.

 4. Mandatory Indemnification. Subject to Section 9 below, the Company shall indemnify the
Indemnitee: 
 4.1 Third Party Actions. If the Indemnitee is a person who was or is a party or is threatened to be
made a party to any proceeding (other than a proceeding by or in the right of the Company) by reason of the fact that he is or was an agent of the Company, or by reason of anything done or not done by him in any such capacity, against any and all
expenses and liabilities of any type whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) actually and reasonably incurred by him in connection with the investigation, defense,
settlement or appeal of such proceeding if he acted in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the Company and, with respect to any criminal action or proceeding, had no reasonable cause
to believe his conduct was unlawful; and 

  
 2 








 4.2 Derivative Actions. If the Indemnitee is a person who was or is a party or
is threatened to be made a party to any proceeding by or in the right of the Company to procure a judgment in its favor by reason of the fact that he is or was an agent of the Company, or by reason of anything done or not done by him in any such
capacity, against any amounts paid in settlement of any such proceeding and all expenses actually and reasonably incurred by him in connection with the investigation, defense, settlement or appeal of such proceeding if he acted in good faith and in
a manner he reasonably believed to be in, or not opposed to, the best interests of the Company; except that no indemnification under this subsection shall be made in respect of any claim, issue or matter in such proceeding as to which such
person shall have been finally adjudged to be liable to the Company by a court of competent jurisdiction due to willful misconduct of a culpable nature in the performance of his duty to the Company, unless and only to the extent that the Court of
Chancery or the court in which such proceeding was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for
such amounts which the Court of Chancery or such other court shall deem proper; and 
 4.3 Exception for Amounts Covered
by Insurance. Notwithstanding the foregoing, the Company shall not be obligated to indemnify the Indemnitee for expenses or liabilities of any type whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or penalties
and amounts paid in settlement) to the extent such have been paid directly to the Indemnitee by D&O Insurance. 
 5.
Partial Indemnification and Contribution. 
 5.1 Partial Indemnification. If the Indemnitee is
entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any expenses or liabilities of any type whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or penalties and
amounts paid in settlement) incurred by him or her in the investigation, defense, settlement or appeal of a proceeding but is not entitled, however, to indemnification for all of the total amount thereof, the Company shall indemnify the Indemnitee
for the portion thereof to which the Indemnitee is entitled. 
 5.2 Contribution. If the Indemnitee is not
entitled to the indemnification provided in Section 4 for any reason other than the statutory limitations set forth in the Law, then in respect of any threatened, pending or completed proceeding in which the Company is jointly liable with the
Indemnitee (or would be if joined in such proceeding), the Company shall contribute to the amount of expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by
the Indemnitee in such proportion as is appropriate to reflect (i) the relative benefits received by the Company on the one hand and the Indemnitee on the other hand from the transaction from which such proceeding arose and (ii) the
relative fault of the Company on the one hand and of the Indemnitee on the other hand in connection with the events which resulted in such expenses, judgments, fines or settlement amounts, as well as any other relevant equitable considerations. The
relative fault of the Company on the one hand and of the Indemnitee on the other hand shall be determined by reference to, among other things, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent
the circumstances resulting in such expenses, judgments, fines or settlement amounts. The Company agrees that it would not be just 

  
 3 








 
and equitable if contribution pursuant to this Section 5 were determined by pro rata allocation or any other method of allocation that does not take account of the foregoing equitable
considerations. 
 6. Mandatory Advancement of Expenses. 

6.1 Advancement. Subject to Section 9 below and except as prohibited by law, the Company shall advance all expenses
actually and reasonably incurred by the Indemnitee in connection with the investigation, defense, settlement or appeal of any proceeding to which the Indemnitee is a party or is threatened to be made a party by reason of the fact that the Indemnitee
is or was an agent of the Company or by reason of anything done or not done by him in any such capacity. The Indemnitee hereby undertakes to promptly repay such amounts advanced only if, and to the extent that, it shall ultimately be determined that
the Indemnitee is not entitled to be indemnified by the Company under the provisions of this Agreement, the Certificate of Incorporation or Bylaws of the Company, the Law or otherwise. The advances to be made hereunder shall be paid by the Company
to the Indemnitee within thirty (30) days following delivery of a written request therefor by the Indemnitee to the Company accompanied by reasonable supporting documentation of the expenses incurred by the Indemnitee. 

6.2 Exception. Notwithstanding the foregoing provisions of this Section 6, the Company shall not be obligated to
advance any expenses to the Indemnitee arising from a lawsuit filed directly by the Company against the Indemnitee if an absolute majority of the members of the Board reasonably determines in good faith, within thirty (30) days of the
Indemnitee’s request to be advanced expenses, that the facts known to them at the time such determination is made demonstrate clearly and convincingly that the Indemnitee acted in bad faith. If such a determination is made, the Indemnitee may
have such decision reviewed by another forum, in the manner set forth in Sections 8.3, 8.4 and 8.5 hereof, with all references therein to “indemnification” being deemed to refer to “advancement of expenses,” and the burden
of proof shall be on the Company to demonstrate clearly and convincingly that, based on the facts known at the time, the Indemnitee acted in bad faith. The Company may not avail itself of this Section 6.2 as to a given lawsuit if, at any time
after the occurrence of the activities or omissions that are the primary focus of the lawsuit, the Company has undergone a change in control. For this purpose, a change in control shall mean a given person or group of affiliated persons or groups
increasing their beneficial ownership interest in the Company by at least twenty (20) percentage points without advance Board approval. 
 7. Notice and Other Indemnification Procedures. 
 7.1
Promptly after receipt by the Indemnitee of notice of the commencement of or the threat of commencement of any proceeding, the Indemnitee shall, if the Indemnitee believes that indemnification with respect thereto may be sought from the Company
under this Agreement, notify the Company of the commencement or threat of commencement thereof. 
 7.2 If, at the time of
the receipt of a notice of the commencement of a proceeding pursuant to Section 7.1 hereof, the Company has D&O 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 shall 

  
 4 








 
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 D&O Insurance policies. 
 7.3 In the event the Company shall be obligated to advance the expenses for any
proceeding against the Indemnitee, the Company, if appropriate, shall be entitled to assume the defense of such proceeding, with counsel approved by the Indemnitee (which approval shall not be unreasonably withheld), upon the delivery to the
Indemnitee of written notice of its election to do so. After delivery of such notice, approval of such counsel by the Indemnitee and the retention of such counsel by the Company, the Company will not be liable to the Indemnitee under this Agreement
for any fees of counsel subsequently incurred by the Indemnitee with respect to the same proceeding, provided that: (a) the Indemnitee shall have the right to employ his or her own counsel in any such proceeding at the Indemnitee’s
expense; (b) the Indemnitee shall have the right to employ his or her own counsel in connection with any such proceeding, at the expense of the Company, if such counsel serves in a review, observer, advice and counseling capacity and does not
otherwise materially control or participate in the defense of such proceeding; and (c) if (i) the employment of counsel by the Indemnitee has been previously authorized by the Company, (ii) the Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and the Indemnitee in the conduct of any such defense or (iii) the Company shall not, in fact, have employed counsel to assume the defense of such proceeding, then the fees
and expenses of the Indemnitee’s counsel shall be at the expense of the Company. 
 8. Determination of Right
to Indemnification. 
 8.1 To the extent the Indemnitee has been successful on the merits or otherwise in defense
of any proceeding referred to in Section 4.1 or 4.2 of this Agreement or in the defense of any claim, issue or matter described therein, the Company shall indemnify the Indemnitee against expenses actually and reasonably incurred by him or her
in connection with the investigation, defense or appeal of such proceeding, or such claim, issue or matter, as the case may be. 

8.2 In the event that Section 8.1 is inapplicable, or does not apply to the entire proceeding, the Company shall nonetheless
indemnify the Indemnitee unless the Company shall prove by clear and convincing evidence to a forum listed in Section 8.3 below that the Indemnitee has not met the applicable standard of conduct required to entitle the Indemnitee to such
indemnification. 
 8.3 The Indemnitee shall be entitled to select the forum in which the validity of the Company’s
claim under Section 8.2 hereof that the Indemnitee is not entitled to indemnification will be heard from among the following, except that the Indemnitee can select a forum consisting of the stockholders of the Company only with the
approval of a quorum of the Board consisting of directors who are not parties to the proceeding for which indemnification is being sought: 
 (a) A quorum of the Board consisting of directors who are not parties to the proceeding for which indemnification is being sought; 

  
 5 








 (b) The stockholders of the Company; 

(c) Legal counsel mutually agreed upon by the Indemnitee and the Board, which counsel shall make such determination in a written
opinion; 
 (d) A panel of three arbitrators, one of whom is selected by the Company, another of whom is selected by the
Indemnitee and the last of whom is selected by the first two arbitrators so selected; or 
 (e) The Court of Chancery of
Delaware. 
 8.4 As soon as practicable, and in no event later than thirty (30) days after the forum has been
selected pursuant to Section 8.3 above, the Company shall, at its own expense, submit to the selected forum its claim that the Indemnitee is not entitled to indemnification, and the Company shall act in the utmost good faith to assure the
Indemnitee a complete opportunity to defend against such claim. 
 8.5 If the forum selected in accordance with
Section 8.3 hereof is not a court, then after the final decision of such forum is rendered, the Company or the Indemnitee shall have the right to apply to the Court of Chancery of Delaware, for the purpose of appealing the decision of such
forum, provided that such right is executed within sixty (60) days after the final decision of such forum is rendered. If the forum selected in accordance with Section 8.3 hereof is a court, then the rights of the Company or the
Indemnitee to appeal any decision of such court shall be governed by the applicable laws and rules governing appeals of the decision of such court. 
 8.6 Notwithstanding any other provision in this Agreement to the contrary, the Company shall indemnify the Indemnitee against all expenses incurred by the Indemnitee in connection with any hearing
or proceeding under this Section 8 involving the Indemnitee and against all expenses incurred by the Indemnitee in connection with any other proceeding between the Company and the Indemnitee involving the interpretation or enforcement of the
rights of the Indemnitee under this Agreement unless a court of competent jurisdiction finds that each of the material claims and/or defenses of the Indemnitee in any such proceeding was frivolous or not made in good faith. 

9. Exceptions. Any other provision herein to the contrary notwithstanding, the Company shall not be obligated
pursuant to the terms of this Agreement: 
 9.1 Claims Initiated by Indemnitee. To indemnify or advance expenses
to the Indemnitee with respect to proceedings or claims initiated or brought voluntarily by the Indemnitee and not by way of defense, except with respect to proceedings specifically authorized by the Board or brought to establish or enforce a
right to indemnification and/or advancement of expenses arising under this Agreement, the charter documents of the Company or any subsidiary or any statute or law or otherwise, but such indemnification or advancement of expenses may be provided by
the Company in specific cases if the Board finds it to be appropriate; or 

  
 6 








 9.2 Unauthorized Settlements. To indemnify the Indemnitee hereunder for any
amounts paid in settlement of a proceeding unless the Company consents in advance in writing to such settlement, which consent shall not be unreasonably withheld; or 
 9.3 Securities Law Actions. To indemnify the Indemnitee on account of any suit in which judgment is rendered against the Indemnitee for an accounting of profits made from the purchase or
sale by the Indemnitee of securities of the Company pursuant to the provisions of Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto or similar provisions of any federal, state or local statutory law; or 

9.4 Unlawful Indemnification. To indemnify the Indemnitee if a final decision by a court having jurisdiction in the matter
shall determine that such indemnification is not lawful. In this respect, the Company and the Indemnitee have been advised that the Securities and Exchange Commission takes the position that indemnification for liabilities arising under the federal
securities laws is against public policy and is, therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication. 
 10. Non-Exclusivity. The provisions for indemnification and advancement of expenses set forth in this Agreement shall not be deemed exclusive of any other rights which the Indemnitee
may have under any provision of law, the Company’s Certificate of Incorporation or Bylaws, the vote of the Company’s stockholders or disinterested directors, other agreements or otherwise, both as to action in the Indemnitee’s
official capacity and to action in another capacity while occupying his position as an agent of the Company, and the Indemnitee’s rights hereunder shall continue after the Indemnitee has ceased acting as an agent of the Company and shall inure
to the benefit of the heirs, executors and administrators of the Indemnitee. 
 11. General Provisions.

 11.1 Interpretation of Agreement. It is understood that the parties hereto intend this Agreement to be
interpreted and enforced so as to provide indemnification and advancement of expenses to the Indemnitee to the fullest extent now or hereafter permitted by law, except as expressly limited herein. 

11.2 Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable
for any reason whatsoever, then: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, all portions of any paragraphs of this Agreement containing any such provision held to
be invalid, illegal or unenforceable that are not themselves invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Agreement (including, without
limitation, all portions of any paragraphs of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable and to give effect to Section 11.1 hereof. 
 11.3
Modification and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No 

  
 7 








 
waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provision hereof (whether or not similar), nor shall such waiver constitute a
continuing waiver. 
 11.4 Subrogation. In the event of full payment under this Agreement, the Company shall be
subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee, who shall execute all documents required and shall do all acts that may be necessary or desirable to secure such rights and to enable the Company
effectively to bring suit to enforce such rights. 
 11.5 Counterparts. This Agreement may be executed in one or
more counterparts, which shall together constitute one agreement. 
 11.6 Successors and Assigns. The terms of

 11.8 Governing Law. This Agreement shall be governed exclusively by and construed according to the laws of the
State of Delaware, without giving effect to that body of laws pertaining to conflict of laws. 
 11.9 Consent to
Jurisdiction. The Company and the 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. 
 11.10 Attorneys’ Fees. In the event Indemnitee is required to bring any action to enforce
rights under this Agreement (including, without limitation, the expenses of any Proceeding described in Section 1.3) the Indemnitee shall be entitled to all reasonable fees and expenses in bringing and pursuing such action, unless a court of
competent jurisdiction finds each of the material claims of the Indemnitee in any such action was frivolous and not made in good faith.
