Loan and Security Agreement

 Exhibit 10.1 
 AMENDED AND RESTATED LOAN AND SECURITY AGREEMENT 
 THIS AMENDED AND
RESTATED LOAN AND SECURITY AGREEMENT (this “Agreement”) is dated as of December 29, 2011 (the “Effective Date”) between SILICON VALLEY BANK, a California corporation (“Bank”), and LUCA
TECHNOLOGIES INC., a Delaware corporation (“Borrower”). Borrower and Lender are parties to a Loan and Security Agreement dated as of April 30, 2008 (the “Original Agreement”) pursuant to which Bank made
certain advances (the “Term Loan”) to Borrower, which Borrower is repaying. Borrower has requested additional Credit Extensions from Bank. This Agreement amends and restates the terms of the Original Agreement to confirm
Borrower’s repayment of the Term Loan and to provide for those Credit Extensions. The parties agree as follows: 
  

	1.	ACCOUNTING AND OTHER TERMS 

Accounting terms not defined in this Agreement shall be construed following GAAP. Calculations and determinations must be made following
GAAP. Capitalized terms not otherwise defined in this Agreement shall have the meanings set forth in Section 13. All other terms contained in this Agreement, unless otherwise indicated, shall have the meaning provided by the Code to the extent
such terms are defined therein. 
  

	2.	LOAN AND TERMS OF PAYMENT 

2.1 Promise to Pay. Borrower hereby unconditionally promises to pay Bank the outstanding principal amount of all Credit Extensions
and accrued and unpaid interest thereon as and when due in accordance with this Agreement. 
 2.1.1 Term Loan. Borrower
confirms that, as of the Effective Date, the outstanding principal balance of the Term Loan made under the Original Agreement is $$416,666.77. Borrower shall continue to make equal principal payments of $83,333.33, plus, subject to
Section 2.2(b), accrued interest at a fixed rate equal to 4.0% per annum, on account of the Term Loan on the last day of each month (or the last Business Day in a month in which there are fewer than 30 days) through April 30, 2012, on
which date the entire unpaid principal balance of the Term Loan and all accrued but unpaid interest shall be due and payable. 

2.1.2 Credit Extensions under the Revolving Line. 
 (a) Availability. Subject to the terms of this Agreement, Bank shall issue or have issued Letters of Credit denominated in Dollars in an aggregate amount of up to the Availability Amount and
shall honor drawings under the Letters of Credit issued hereunder. The aggregate amount utilized for the issuance of Letters of Credit shall at all times reduce the amount otherwise available for Letters of Credit or Advances under the Revolving
Line. This is a revolving facility, pursuant to which Borrower may request Letters of Credit and Advances from time to time, for so long as the aggregate Letters of Credit and Advances do not exceed the Availability Amount. Except to reimburse Bank
for any draws made in respect of Letters of Credit pursuant to Section 2.1.2(c), Borrower may not request any Advances under this Agreement. 
 (b) Letter of Credit Terms. All Letters of Credit shall be in form and substance acceptable to Bank in its sole discretion and shall be subject to the terms and conditions of Bank’s
standard Application and Letter of Credit Agreement (the “Letter of Credit Application”). Borrower shall execute any further documentation in connection with the Letters of Credit as Bank may reasonably request. Borrower further
agrees to be bound by the regulations and interpretations of the issuer of any Letters of Credit guarantied by Bank and opened for Borrower’s account or by Bank’s interpretations of any Letter of Credit issued by Bank for Borrower’s
account, and Borrower understands and agrees that Bank shall not be liable for any error, negligence, or mistake, whether of omission or commission, in following Borrower’s instructions or those contained in the Letters of Credit or any
modifications, amendments, or supplements thereto. If any provisions of any Letter of Credit Application or other documentation executed by Borrower at Bank’s request in connection with a Letter of Credit conflict with any provisions of this
Agreement, the provisions of this Agreement shall govern and control. 
 (c) Reimbursement. Upon any draw on a
Letter of Credit, Borrower shall immediately reimburse Bank in immediately available funds for the amount of such draw. Any amount not reimbursed within 

 
one (1) Business Day following receipt by Borrower of such notice from Bank shall be deemed an Advance by Bank to Borrower equal to the amount of such draw. Bank may make Advances under this
Agreement based on instructions from a Responsible Officer or his or her designee or without instructions if the Advances are necessary to meet Obligations relating to Letters of Credit issued hereunder that have become due. Amounts borrowed under
this Section 2.1.2 may be repaid and, prior to the Revolving Line Maturity Date, reborrowed, subject to the applicable terms and conditions precedent herein. 
 (d) Termination; Repayment. The Revolving Line terminates on the Revolving Line Maturity Date, on which date the principal amount of all Advances, the unpaid interest thereon, and all other
Obligations relating to the Revolving Line shall be immediately due and payable. Not less than one Business Day before the Revolving Line Maturity Date, Borrower shall provide to Bank cash collateral in an amount equal to 105% of the face amount of
all Letters of Credit then outstanding and remaining undrawn plus all interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its good faith business judgment), to secure all of the Obligations relating to
such Letters of Credit. If Borrower has not secured to Bank’s satisfaction (acting reasonably) Bank’s obligations with respect to any Letters of Credit outstanding on the Revolving Line Maturity Date, then, effective as of such date, the
balance in any deposit accounts held by Bank and the certificates of deposit or time deposit accounts issued by Bank in Borrower’s name (and any interest paid thereon or proceeds thereof, including any amounts payable upon the maturity or
liquidation of such certificates or accounts), shall automatically secure such obligations to the extent of the then continuing or outstanding and undrawn Letters of Credit. Borrower authorizes Bank to hold such balances in pledge and to decline to
honor any drafts thereon or any requests by Borrower or any other Person to pay or otherwise transfer any part of such balances for so long as the Letters of Credit are outstanding. Upon termination of Bank’s obligations with respect to Letters
of Credit outstanding on the Revolving Line Maturity Date, any excess cash collateral provided to Bank or otherwise held by Bank under this Section 2.1.2(d) will promptly be returned to Borrower. 

2.2 Payment of Interest on the Credit Extensions. 
 (a) Interest Rate. Subject to Section 2.2(b), the outstanding principal amount of the Advances shall accrue interest at a floating rate per annum equal to the greater of (i) four
percent (4.0%) or (ii) three quarters of one percent (0.75%) above the Prime Rate, which interest shall be payable monthly in accordance with Section 2.3(f) below. Interest on the outstanding principal balance of the Term Loan is
addressed in Section 2.1.1. 
 (b) Default Rate. Immediately upon the occurrence and during the continuance
of an Event of Default, Obligations shall bear interest at a rate per annum which is five percentage points above the rate effective immediately before the Event of Default (the “Default Rate”). Payment or acceptance of the
increased interest rate provided in this Section 2.2(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Bank. 

(c) Adjustment to Interest Rate. Changes to the interest rate of any Credit Extension other than the Term Loan shall be
effective on the effective date of any change to the Prime Rate and to the extent of any such change. 
 (d) 360-Day
Year. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed. 

(e) Debit of Accounts. Bank may debit any of Borrower’s deposit accounts, including the Designated
Deposit Account (but excluding deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such), for principal
and interest payments or any other amounts Borrower owes Bank under the Loan Documents when due. Bank agrees to notify Borrower promptly after any such debit, provided that the failure to give such notice shall not affect the validity of such
debit. These debits shall not constitute a set-offPayments. Unless otherwise provided, interest is payable in arrears monthly on the first calendar day of each month following the Effective Date. Payments of principal and/or interest received
after 12:00 p.m. Pacific time are considered received at the opening of business on the next Business Day. When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as
applicable, shall continue to accrue. 

  
 -2-

 2.3 Fees. Borrower shall pay to Bank: 

(a) Commitment Fee. None. 
 (b) Letter of Credit Fee. A fee equal to 2.0% of the face amount of each Letter of Credit (not in any case less than $500), such fee to be payable on the date of issuance of the Letter of
Credit and each anniversary date of such issuance for so long as such Letter of Credit is outstanding, which fee is nonrefundable. 
 (c) Bank Expenses. All Bank Expenses (including reasonable attorneys’ fees and expenses) incurred through and after the Effective Date, upon written request by Bank which shall be paid
within 30 days of the written request. 
  

	3.	CONDITIONS OF LOANS

 (d) Borrower shall have delivered duly executed original signatures to the completed Borrowing Resolutions for Borrower; 
 (e) Bank shall have received certified copies, dated as of a recent date, of financing statement searches, as Bank shall request, accompanied by written evidence (including any UCC termination

 (a)
the representations and warranties in Section 5 shall be true in all material respects on the Funding Date of each Credit Extension; provided, however, that such materiality qualifier shall not be applicable to any representations and
warranties that already are qualified or modified by materiality in the text thereof; and provided, further that those representations and warranties expressly referring to a specific date shall be true in all material respects as of such date, and
no Default or Event of Default shall have occurred and be continuing or result from the Credit Extension. Each Credit Extension is Borrower’s representation and warranty on that date that the representations and warranties in Section 5 are

 -3-

 3.3 Covenant to Deliver.

 Borrower agrees to deliver to Bank each item required to be delivered to Bank under this Agreement as a condition to any
Credit Extension. Borrower expressly agrees that the extension of a Credit Extension prior to the receipt by Bank of any such item shall not constitute a waiver by Bank of Borrower’s obligation to deliver such item, and any such extension in
the absence of a required item shall be in Bank’s sole discretion. 
  

	4.	CREATION OF SECURITY INTEREST 

 4.1 Grant of Security Interest. To secure the payment and performance in full of all of the Obligations, Borrower grants Bank a continuing security interest in, and pledges to Bank, all of
Borrower’s right, title and interest in, to and under the Collateral, wherever located, whether now owned or hereafter acquired or arising, and all proceeds and products thereof. Borrower represents, warrants, and covenants that the security
interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral (subject only to Permitted Liens that may have superior priority to Bank’s Lien under this Agreement). If Borrower
shall acquire a commercial tort claim, Borrower shall promptly notify Bank in a writing signed by Borrower of the general details thereof and, if requested by Bank, grant to Bank in such writing a security interest therein and in the proceeds
thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to Bank. 

Borrower acknowledges that it has entered, and/or may enter, into Bank Services Agreements with Bank. Regardless of the terms of any Bank
Services Agreement, any amounts Borrower owes Bank thereunder shall be deemed to be Obligations hereunder, and satisfaction of such Obligations shall be secured by the security interest in the Collateral granted herein until such security interest
is terminated or released as provided in this Agreement. 
 If this Agreement is terminated, Bank’s Lien in the Collateral
shall continue until the Obligations (other than inchoate indemnity obligations) are satisfied in full, and at such time, Bank shall, at Borrower’s sole cost and expense, terminate its security interest in the Collateral and all rights therein
shall revert to Borrower. Notwithstanding the foregoing, in the event (x) all Obligations (other than inchoate indemnity obligations), except Obligations with respect to Bank Services and Obligations with respect to outstanding and undrawn
Letters of Credit, are satisfied in full, and (y) this Agreement is terminated, Bank shall terminate the security interest granted herein upon Borrower providing (I) cash collateral for outstanding and undrawn Letters of Credit that
satisfies the requirements of Section 2.1.2(d) and (II) cash collateral acceptable to Bank in its good faith business judgment for Bank Services, if any. Upon any termination of Bank’s Lien in the Collateral under this Section 4.1,
Bank shall, at Borrower’s sole cost and expense, deliver such documents and make such filings as Borrower shall reasonably request to evidence such termination. 
 4.2 Priority of Security Interest. Borrower represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected
security interest in the Collateral (subject only to Permitted Liens that may have superior priority to Bank’s Lien under this Agreement). If Borrower shall acquire a commercial tort claim, Borrower shall promptly notify Bank in a writing
signed by Borrower of the general details thereof and grant to Bank in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory
to Bank. 
 4.3 Authorization to File Financing Statements. Borrower authorizes Bank to file financing statements with
all appropriate jurisdictions to perfect or protect Bank’s interest or rights hereunder. 
  

	5.	REPRESENTATIONS AND WARRANTIES 

 Except as disclosed in the Perfection Certificate, Borrower represents and warrants as follows: 

  
 -4-

 5.1 Due Organization and Authorization. Borrower is duly existing and in good
standing in its jurisdiction of formation and is qualified and licensed to do business and is in good standing in any jurisdiction in which the conduct of its business or its ownership of property requires that it be qualified except where the
failure to do so could not reasonably be expected to have a material adverse effect on Borrower’s business. In connection with this Agreement, Borrower has delivered to Bank a completed certificate entitled “Perfection Certificate”.
Borrower represents and warrants to Bank that, as of the Effective Date: (a) Borrower’s exact legal name is that indicated on the Perfection Certificate and on the signature page hereof; (b) Borrower is an organization of the type and
is organized in the jurisdiction set forth in the Perfection Certificate; (c) the Perfection Certificate accurately sets forth Borrower’s organizational identification number or accurately states that Borrower has none; (d) the
Perfection Certificate accurately sets forth Borrower’s place of business, or, if more than one, its chief executive office as well as Borrower’s mailing address (if different than its chief executive office); (e) Borrower (and each
of its predecessors) has not, in the five (5) years preceding the Effective Date, changed its state of formation, organizational structure or type, or any organizational number assigned by its jurisdiction (unless included on the Perfection
Certificate); and (f) all other information set forth on the Perfection Certificate pertaining to Borrower and each of its Subsidiaries is accurate and complete in all material respects. If Borrower is not now a Registered Organization but
later becomes one, Borrower shall promptly notify Bank of such occurrence and provide Bank with Borrower’s organizational identification number. 
 The execution, delivery and performance by Borrower of the Loan Documents and the Warrant have been duly authorized by all requisite corporate action, and do not conflict with Borrower’s
organizational documents, nor constitute an event of default under any material agreement by which Borrower is bound. Borrower is not in default under any agreement to which it is a party or by which it is bound in which the default could have a
material adverse effect on Borrower’s business. 
 5.2 Collateral. Borrower has good title to, or has sufficient
rights by license or otherwise in, and the power to grant a security interest in each item of the Collateral upon which it purports to grant a Lien hereunder, free and clear of any and all Liens except Permitted Liens. Borrower has no deposit
accounts other than the deposit accounts with Bank, the deposit accounts, if any, described in the Perfection Certificate delivered to Bank in connection herewith, or of which Borrower has given Bank notice (such notice shall be deemed to
automatically update the disclosure regarding Deposit Accounts in the Perfection Certificate) and taken such actions as are necessary to give Bank a perfected security interest therein. 

The Collateral is not in the possession of any third party bailee (such as a warehouse) except as otherwise provided in the Perfection
Certificate or as Borrower has given notice pursuant to Section 7.2 (such notice shall be deemed to automatically update such disclosure in the Perfection Certificate). None of the material components of the Collateral shall be maintained at
locations other than as provided in the Perfection Certificate, as Borrower has given Bank notice pursuant to Section 7.2 (such notice shall be deemed to automatically update such disclosure in the Perfection Certificate). In the event that
Borrower, after the date hereof, intends to store or otherwise deliver any material portion of the Collateral to a bailee, then Borrower will first receive the written consent of Bank and such bailee must execute and deliver a bailee agreement in
form and substance satisfactory to Bank in its sole discretion. 
 5.3 Accounts Receivable. For any Accounts, all
statements made and all unpaid balances appearing in all invoices, instruments and other documents evidencing such Accounts are and shall be true and correct in all material respects and all such invoices, instruments and other documents, and all of
Borrower’s Books are genuine and in all material respects what they purport to be. All sales and other transactions underlying or giving rise to each Account shall comply in all material respects with all applicable laws and governmental rules
and regulations. To the best of Borrower’s knowledge, all signatures and endorsements on all documents, instruments, and agreements relating to all Accounts are genuine, and all such documents, instruments and agreements are legally enforceable
in accordance with their terms. 
 5.4 Litigation. Except as disclosed to Bank pursuant to Section 6.2, there are no
actions or proceedings pending or, to the knowledge of the Responsible Officers, threatened in writing by or against Borrower or any of its Subsidiaries which could reasonably be expected to result in liability of more than One Hundred Thousand
Dollars ($100,000). 
 5.5 No Material Deviation in Financial Statements. The consolidated financial statements for
Borrower and any of its Subsidiaries delivered to Bank fairly present in all material respects Borrower’s 

  
 -5-

 
consolidated financial condition and Borrower’s consolidated results of operations as of the dates, and for the periods, indicated therein, subject in the case of the unaudited financial
statements to normal year-end audit adjustments and matters that would be disclosed in footnotes thereto. As of the Effective Date, there has not been any material deterioration in Borrower’s consolidated financial condition since the date of
the most recent financial statements submitted to Bank. 
 5.6 Solvency. The fair salable value of Borrower’s assets
(including goodwill minus disposition costs) exceeds the fair value of its liabilities; Borrower is not left with unreasonably small capital after the transactions in this Agreement; and Borrower is able to pay its debts (including trade debts) as
they mature. 
 5.7 Regulatory Compliance. Borrower is not an “investment company” or a company
“controlled” by an “investment company” under the Investment Company Act. Borrower is not engaged as one of its important activities in extending credit for margin stock (under Regulations T and U of the Federal Reserve Board of
Governors). Borrower is in compliance in all material respects with the Federal Fair Labor Standards Act. Borrower is not in violation of any laws, ordinances or rules, the violation of which could reasonably be expected to have a material adverse
effect on its business. None of Borrower’s or any of its Subsidiaries’ properties or assets has been used by Borrower or any Subsidiary or, to the best of Borrower’s knowledge, by previous Persons, in disposing, producing, storing,
treating, or transporting any hazardous substance other than legally. Borrower and each of its Subsidiaries have obtained all consents, approvals and authorizations of, made all declarations or filings with, and given all notices to, all government
authorities that are necessary to continue its business as currently conducted, except, where failure to do so could not reasonably, in each such case, be expected to result in a material adverse effect on the Borrower’s business. 

5.8 Subsidiaries; Investments. Borrower does not own any stock, partnership interest or other equity securities except for
Permitted Investments. As of the Effective Date, Patriot and Patriot Energy Gathering LLC are the only Subsidiaries of Borrower. 
 5.9 Tax Returns and Payments; Pension Contributions. Borrower has timely filed all required material tax returns and reports, and Borrower has timely paid all material foreign, federal, state and
local taxes, assessments, deposits and contributions owed by Borrower. Borrower may defer payment of any contested taxes, provided that Borrower (a) in good faith contests its obligation to pay the taxes by appropriate proceedings promptly and
diligently instituted and conducted and (b) with respect to contested amounts in excess of One Hundred Thousand Dollars ($100,000), notifies Bank in writing of the commencement of, and any material development in, the proceedings and posts
bonds or takes any other steps required to prevent the governmental authority levying such contested taxes from obtaining a Lien upon any of the Collateral that is other than a “Permitted Lien”. Except as disclosed to Bank in writing,
Borrower is unaware of any claims or adjustments proposed for any of Borrower’s prior tax years which could result in additional taxes becoming due and payable by Borrower. Borrower has paid all amounts necessary to fund all present pension,
profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not permitted partial or complete termination of, or permitted the occurrence of any other event with
respect to, any such plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 

5.10 Use of Proceeds. Borrower shall use the proceeds of the Credit Extensions solely as working capital and to fund its general
business requirements and not for personal, family, household or agricultural purposes. 
 5.11 Full Disclosure. No
written representation, warranty or other statement of Borrower in any certificate or written statement given to Bank, as of the date such representations, warranties, or other statements were made, taken together with all such written certificates
and written statements given to Bank, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained in the certificates or statements not misleading (it being recognized by Bank that
the projections and forecasts provided by Borrower in good faith and based upon reasonable assumptions are not viewed as facts and that actual results during the period or periods covered by such projections and forecasts may differ from the
projected or forecasted results). 

  
 -6-

	6.	AFFIRMATIVE COVENANTS 

 So
long as any Obligation shall remain unpaid (other than inchoate indemnity obligations) or Bank shall have any commitment to make Credit Extensions hereunder (it being understood and agreed, however, that, notwithstanding the foregoing,
Borrower’s obligations under this Section 6 shall terminate upon termination of this Agreement), Borrower shall do all of the following: 
 6.1 Government Compliance. Except as permitted by Section 7.3, maintain its and all its Subsidiaries’ legal existence and good standing in their respective jurisdictions of formation and
maintain qualification in each jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on Borrower’s business or operations. Borrower shall comply, and have each Subsidiary comply, with all
laws, ordinances and regulations to which it is subject, noncompliance with which could have a material adverse effect on Borrower’s business. 
 6.2 Financial Statements, Reports, Certificates. 
 (a) Deliver to
Bank: (i) as soon as available, but no later than thirty five (35) days after the last day of each month(commencing with the month ending December 31, 2011), a company prepared consolidated balance sheet, income statement, and

threatened in writing against Borrower or any of its Subsidiaries that could reasonably be expected to result in damages or costs to Borrower or any of its Subsidiaries of One Hundred Thousand Dollars ($100,000) or more; (vi) prompt notice of
an event that materially and adversely affects the value of the intellectual property that is material to the business of Borrower; (vii) annual financial projections commensurate with those provided to the Borrower’s venture capital

any indebtedness outside the ordinary course of business; and (ix) other financial information reasonably requested by Bank.

and marketable condition, free from material defects. Returns and allowances between Borrower and its Account Debtors shall follow Borrower’s customary practices. Borrower must promptly notify Bank of all returns, recoveries, disputes and

 6.4 Taxes; Pensions. Make, and cause each of
its Subsidiaries to make, timely payment of all material foreign, federal, state, and local taxes or assessments (other than taxes and assessments which Borrower is contesting pursuant to the terms of Section 5.9 hereof) and shall deliver to
Bank, on demand, appropriate certificates attesting to such payments, and pay all amounts necessary to fund all present pension, profit sharing and deferred compensation plans in accordance with their terms. 

6.5 Insurance. Keep its business and the Collateral insured for risks and in amounts standard for companies in Borrower’s
industry and location and as Bank may reasonably request. Insurance policies shall be in a form, with companies, and in amounts that are reasonably satisfactory to Bank. All property policies shall have a lender’s loss payable endorsement
showing Bank as an additional loss payee and waive subrogation against Bank, and all liability policies shall show, or have endorsements showing, Bank as an additional insured. All policies (or

  
 -7-

 
the loss payable and additional insured endorsements) shall provide that the insurer must give Bank at least twenty (20) days notice before canceling, amending, or declining to renew its
policy. At Bank’s request, Borrower shall deliver certified copies of policies and evidence of all premium payments. Proceeds payable under any casualty policy shall be payable to Borrower for repair or replacement of the damaged or destroyed
property so long as no Event of Default is outstanding; provided, however, that if an Event of Default is outstanding, at Bank’s option, such proceeds may be payable to Bank on account of the Obligations. If Borrower fails to obtain insurance
as required under this Section 6.5 or to pay any amount or furnish any required proof of payment to third persons and Bank, Bank may, after reasonable prior written notice to Borrower, make all or part of such payment or obtain such insurance
policies required in this Section 6.5, and take any action under the policies Bank reasonably deems prudent.

Borrower’s business to be abandoned, forfeited or dedicated to the public without Bank’s written consent except where Borrower in the exercise of its business judgment deems it in its best interest to do so. 

6.9 Litigation Cooperation. From the date hereof and continuing through the termination of this Agreement, make available to Bank,
without expense to Bank, on reasonable prior notice and at reasonable times and intervals, Borrower and its officers, employees and agents and Borrower’s books and records, to the extent that Bank may deem them reasonably necessary to prosecute

employees or agents, be required to provide any information or documentation subject to attorney-client privilege, work product doctrine or other applicable legal privileges, unless access to the same is granted by court order. 

6.10 Patriot.

 -8-

 (c) Borrower shall not permit Patriot to conduct business other than the acquisition,
divestiture, restoration, production and development of oil and gas wells and any other businesses reasonably related or ancillary thereto. 
 6.11 Further Assurances. Borrower shall execute any further instruments and take further action as Bank reasonably requests to perfect or continue Bank’s Lien in the Collateral or to effect
the purposes of this Agreement. 
  

	7.	NEGATIVE COVENANTS 

 So
long as any Obligation shall remain unpaid (other than inchoate indemnity obligations) or Bank shall have any commitment to make Credit Extensions hereunder (it being understood and agreed, however, that, notwithstanding the foregoing,
Borrower’s obligations under this Section 7 shall terminate upon termination of this Agreement), Borrower shall not do any of the following without Bank’s prior written consent: 

7.1 Dispositions. Convey, sell, lease, transfer or otherwise dispose of (collectively, “Transfer”), or permit any
of its Restricted Subsidiaries to Transfer, all or any part of the Collateral or any other part of Borrower’s or such Restricted Subsidiary’s property, except for Transfers (a) of Inventory, use of cash, or liquidation or sale of cash

 7.2 Changes in Business, Management, Control, or Business
Locations. (a) Engage in or permit any of its Restricted Subsidiaries to engage in any business other than the businesses currently engaged in by Borrower and such Restricted Subsidiary, as applicable, or reasonably related or ancillary

connection with such liquidation or dissolution); or (c) (i) have a change in Chief Executive Officer or Chief Financial Officer unless Borrower has provided Bank notice or (ii) enter into any transaction or series of related
transactions in which the stockholders of Borrower immediately prior to the first such transaction own less than 49% of the voting stock of Borrower immediately after giving effect to such transaction or related series of such transactions (other
than by the sale of Borrower’s equity securities in a public offering. Borrower shall not, without prior written notice to Bank (such notice shall be deemed to update such disclosure in the Perfection Certificate): (1) add any new

(3) change its organizational structure or type, (4) change its legal name, or (5) change any organizational number (if any) assigned by its jurisdiction of organization. 

7.3 Mergers or Acquisitions. Merge or consolidate, or permit any of its Restricted Subsidiaries to merge or consolidate, with any
other Person, or acquire, or permit any of its Restricted Subsidiaries to acquire, all or substantially all of the capital stock or property of another Person other than Permitted Investments. A Restricted Subsidiary may merge or consolidate into
another Restricted Subsidiary or into Borrower. 
 7.4 Indebtedness. Create, incur, assume, or be liable for any
Indebtedness, or permit any Restricted Subsidiary to do so, other than Permitted Indebtedness. 
 7.5 Encumbrance.

so, except for Permitted Liens, and, except as otherwise provided or contemplated in the Loan Documents, permit any Collateral not to be subject to the first priority security interest granted herein. 

  
 -9-

 7.6 Maintenance of Collateral Accounts. Maintain any Collateral Account except
pursuant to the terms of Section 6.6.(b) hereof. 
 7.7 Distributions; Investments. (a) Directly or indirectly

from former employees, directors or consultants of Borrower under the terms of applicable repurchase agreements, provided that the aggregate cash consideration paid by Borrower in connection with such repurchases shall not exceed Fifty Thousand
Dollars ($50,000) in the aggregate in any fiscal year, provided that no Event of Default has occurred, is continuing or would exist after giving effect to the repurchases. 
 7.8 Transactions with Affiliates. Directly or indirectly enter into or permit to exist any material transaction with any Affiliate of Borrower, except for (a) transactions expressly permitted
by, and subject to the terms of, this Agreement and the other Loan Documents, (b) compensation and employment arrangements with employees, officers and directors in the ordinary course of business, (c) agreements entered into among the
Company and all or certain of its stockholders in connection with preferred stock or other bona fide equity transactions, including but not limited to the Rights Agreement and Stockholders Agreement, and (d) other transactions that are in the
ordinary course of Borrower’s business, upon fair and reasonable terms that are no less favorable to Borrower than would be obtained in an arm’s length transaction with a non-affiliated Person. 

7.9 Subordinated Debt. (a) Make or permit any payment on any Subordinated Debt, except under the terms of the subordination,
intercreditor, or other similar agreement to which such Subordinated Debt is subject, or (b) amend any provision in any document relating to the Subordinated Debt which would adversely affect the subordination thereof to Obligations owed to
Bank except as permitted under the terms of the subordination, intercreditor, or other similar agreement to which such Subordinated Debt is subject. 
 7.10 Compliance. Become an “investment company” or a company controlled by an “investment company”, under the Investment Company Act of 1940 or undertake as one of its important
activities extending credit to purchase or carry margin stock (as defined in Regulation U of the Board of Governors of the Federal Reserve System), or use the proceeds of any Credit Extension for that purpose; fail to meet the minimum funding
requirements of ERISA , permit a Reportable Event or Prohibited Transaction, as defined in ERISA, to occur; fail to comply with the Federal Fair Labor Standards Act or violate any other law or regulation, or permit any of its Subsidiaries to do so,

the occurrence of any other event with respect to, any present pension, profit sharing and deferred compensation plan which could reasonably be expected to result in any liability of Borrower, including any liability to the Pension Benefit Guaranty
Corporation or its successors or any other governmental agency. 
  

	8.	EVENTS OF DEFAULT 

 Any
one of the following shall constitute an event of default (an “Event of Default”) under this Agreement: 

8.1 Payment Default. Borrower fails to (a) make any payment of principal or interest on any Credit Extension on its due date,
or (b) pay any other Obligations within three (3) Business Days after such Obligations are due and payable. During the cure period, the failure to cure the payment default is not an Event of Default (but no Credit Extension will be made
during the cure period); 
 8.2 Covenant Default. 

(a) Borrower fails to perform any obligation in Sections 6.2 or 6.6 or violates any covenant in Section 7; or 

  
 -10-

 (b) Borrower fails to perform, keep, or observe any other term, provision, condition,
covenant or agreement contained in this Agreement, any Loan Documents, and as to any default (other than those specified elsewhere in this Section 8) under such other term, provision, condition, covenant or agreement that can be cured, has
failed to cure the default within twenty (20) days after Borrower receives written notice thereof from Bank or, if earlier, within twenty (20) days after Borrower reasonably should have known of such default or non-performance; provided,
however, that if the default cannot by its nature be cured within the twenty (20) day period or cannot after diligent attempts by Borrower be cured within such twenty (20) day period, and such default is likely to be cured within a
reasonable time, then Borrower shall have an additional period (which shall not in any case exceed thirty (30) days) to attempt to cure such default, and within such reasonable time period the failure to cure the default shall not be deemed an
Event of Default (but no Credit Extensions shall be made during such cure period). Grace periods provided under this section shall not apply to any other covenants set forth in subsection (a) above; 

8.3 Material Adverse Change. A Material Adverse Change occurs; 

8.4 Attachment. (a) Any material portion of Borrower’s assets is attached, seized, levied on, or comes into possession
of a trustee or receiver and the attachment, seizure or levy is not removed, rescinded or discharged within ten (10) days; (b) the service of process upon Bank seeking to attach, by trustee or similar process, any funds of Borrower or of
any Restricted Subsidiary on deposit with Bank that is not rescinded or dismissed within ten (10) days; (c) Borrower is enjoined, restrained, or prevented by court order from conducting a material part of its business; (d) a judgment
or other claim in excess of One Hundred Thousand Dollars ($100,000) becomes a Lien on any of Borrower’s assets and such lien or encumbrance has not been released or removed within ten (10) days of attaching; or (e) a notice of lien,
levy, or assessment is filed against any of Borrower’s assets by any government agency and not paid within thirty (30) days after Borrower receives notice. These are not Events of Default if stayed or if a bond is posted pending contest by
Borrower (but no Credit Extensions shall be made during the cure period); 
 8.5 Insolvency. Borrower is unable to pay
its debts (including trade debts) as they become due; (b) Borrower begins an Insolvency Proceeding; or (c) an Insolvency Proceeding is begun against Borrower and not dismissed or stayed within forty-five (45) days (but no Credit
Extensions shall be made while of any of the conditions described in clause (a) exist and/or until any Insolvency Proceeding is dismissed); 
 8.6 Other Agreements. There is a default in any agreement to which Borrower is a party with a third party or parties relating to any Indebtedness (other than the Obligations or unsecured
Indebtedness to trade creditors incurred in the ordinary course of business) in the outstanding principal amount in excess of One Hundred Thousand Dollars ($100,000) in the aggregate, which default is not waived or cured within any applicable grace
or cure period and results in a right by such third party or parties, whether or not exercised, to accelerate the maturity of such Indebtedness; 
 8.7 Judgments. A judgment or judgments for the payment of money in an amount, individually or in the aggregate, of at least One Hundred Thousand Dollars ($100,000) (not covered by independent
third-party insurance) shall be rendered against Borrower and shall remain unsatisfied and unstayed for a period of thirty (30) days after the entry thereof (provided that no Credit Extensions will be made prior to the satisfaction or stay of
such judgment); 
 8.8 Misrepresentations. Borrower or any Person acting for Borrower makes any representation, warranty,
or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Bank or to induce Bank to enter this Agreement or any Loan Document, and such representation, warranty, or other statement is incorrect in any
material respect when made; or 
 8.9 Subordinated Debt. A default or breach occurs under any agreement between Borrower
and any creditor of Borrower that signed a subordination, intercreditor, or other similar agreement with Bank, or any creditor that has signed such an agreement with Bank breaches any material terms of such agreement, and in each such case, the
default or breach is not waived or cured within any applicable grace or cure period. 

  
 -11-

	9.	BANK’S RIGHTS AND REMEDIES 

 9.1 Rights and Remedies. While an Event of Default occurs and continues Bank may, without notice or demand, do any or all of the following: 

(a) declare all Obligations immediately due and payable (but if an Event of Default described in Section 8.5 occurs all
Obligations are immediately due and payable without any action by Bank); 
 (b) stop advancing money or extending credit
for Borrower’s benefit under this Agreement or under any other agreement between Borrower and Bank; 
 (c) for any
Letters of Credit, demand that Borrower (i) deposit cash with Bank in an amount equal to 105% of the aggregate face amount of all outstanding Letters of Credit remaining undrawn (plus all interest, fees, and costs due or to become due in
connection therewith (as estimated by Bank in its good faith business judgment)), to secure all of the Obligations relating to such Letters of Credit, as collateral security for the repayment of any future drawings under such Letters of Credit, and
Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all letter of credit fees scheduled to be paid or payable over the remaining term of any such Letters of Credit; 

(d) settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Bank reasonably
considers advisable, notify any Person owing Borrower money of Bank’s security interest in such funds, and verify the amount of such account; 
 (e) make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the Collateral. Borrower shall assemble the Collateral if Bank
requests and make it available at a place or places designated by Bank which are reasonably convenient to Bank and Borrower. Bank may enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and
pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest (other than Permitted Liens that may have superior priority to Bank’s Lien under this Agreement) and pay all expenses incurred in
connection therewith. Borrower grants Bank a license to enter and occupy any of its premises, without charge, to exercise any of Bank’s rights or remedies (provided, that such license shall only be granted with respect to premises that are not
owned by Borrower to the extent such license does not violate or breach the lease or other agreement pursuant to which Borrower has a right to use and occupy such premises); 
 (f) apply to the Obligations any (i) balances and deposits of Borrower it holds, or (ii) any amount held by Bank owing to or for the credit or the account of Borrower (Bank agrees to
notify Borrower promptly after any such application, provided that the failure to give such notice shall not affect the validity of such application); 
 (g) ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, advertise for sale, and sell the Collateral. Except to the extent that such use, assignment, license or sublicense is
expressly prohibited under a license agreement and would result in a breach under such agreement for which such agreement would reasonably be expected to be terminated by such licensor, upon the occurrence of such an Event of Default and the
exercise of its rights under this Section 9.1(g), Bank is hereby granted a non-exclusive, royalty-free license or other right to use, without charge and solely pursuant to this Section 9.1, Borrower’s labels, patents, copyrights, mask
works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as it pertains to the Collateral, solely as necessary in completing production of, advertising for sale, and
selling any Collateral and, solely in connection with Bank’s exercise of its rights under this Section, Borrower’s rights under all licenses and all franchise agreements inure to Bank’s benefit; 

(h) place a “hold” on any account maintained with Bank (excluding accounts exclusively used for payroll, payroll taxes
and other employee wage and benefit payments to or for the benefit of Borrower’s employees and identified to Bank by Borrower as such) and/or deliver a notice of exclusive control, any entitlement order, or other directions or instructions
pursuant to any Control Agreement or similar agreements providing control of any Collateral; and 

  
 -12-

 (i) exercise all rights and remedies available to Bank under the Loan Documents or at
law or equity, including all remedies provided under the Code (including disposal of the Collateral pursuant to the terms thereof). 
 9.2 Power of Attorney. Borrower hereby irrevocably appoints Bank as its lawful attorney-in-fact, exercisable only upon the occurrence and during the continuance of an Event of Default, to:
(a) endorse Borrower’s name on any checks or other forms of payment or security that may come into Bank’s possession; (b) sign Borrower’s name on any invoice or bill of lading for any Account or drafts against Account
Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Bank determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies;
(e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; (f) transfer the
Collateral into the name of Bank or a third party as the Code permits; and (g) sign Borrower’s name on any documents necessary to perfect or continue the perfection of any security interest. Bank’s foregoing appointment as
Borrower’s attorney in fact, and all of Bank’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations) have been fully repaid and performed and Bank’s obligation
to provide Credit Extensions terminates or the earlier termination of this Agreement. 
 9.3 Accounts Verification;
Collection. During the existence of an Event of Default, Bank may notify any Person owing Borrower money of Bank’s security interest in such funds and verify the amount of such account. During the existence of an Event of Default, any
amounts received by Borrower shall be held in trust by Borrower for Bank, and, if requested by Bank, Borrower shall immediately deliver such receipts to Bank in the form received from the Account Debtor, with proper endorsements for deposit.

 9.4 Protective Payments. If Borrower fails to obtain the insurance called for by Section 6.5 or fails to pay any
premium thereon or fails to pay any other amount which Borrower is obligated to pay under this Agreement or any other Loan Document, Bank may, after reasonable written notice to Borrower, obtain such insurance or make such payment. All amounts so
paid by Bank are Bank Expenses, shall be due and payable within five (5) Business Days following demand, and, to the extent not paid when due, shall bear interest at the then highest applicable rate hereinabove provided, and shall be secured by
the Collateral. No payments by Bank are deemed an agreement to make similar payments in the future or Bank’s waiver of any Event of Default. 
 9.5 Application of Payments and Proceeds. Unless an Event of Default has occurred and is continuing, Bank shall apply any funds in its possession, whether from Borrower account balances, payments,
or proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, first, to Bank Expenses, including without limitation, the reasonable costs, expenses, liabilities, obligations and attorneys’ fees
incurred by Bank in the exercise of its rights under this Agreement; second, to the interest due upon any of the Obligations; and third, to the principal of the Obligations and any applicable fees and other charges, in such order as Bank shall
determine in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If an Event of Default has occurred and is continuing, Bank may apply any
funds in its possession, whether from Borrower account balances, payments, proceeds realized as the result of any collection of Accounts or other disposition of the Collateral, or otherwise, to the Obligations in such order as Bank shall determine
in its sole discretion. Any surplus shall be paid to Borrower or other Persons legally entitled thereto; Borrower shall remain liable to Bank for any deficiency. If Bank, in its good faith business judgment, directly or indirectly enters into a
deferred payment or other credit transaction with any purchaser at any sale of Collateral in connection with exercise of Bank’s rights and remedies during the continuance of an Event of Default, Bank shall have the option, exercisable at any
time, of either reducing the Obligations by the principal amount of the purchase price or deferring the reduction of the Obligations until the actual receipt by Bank of cash therefor. 

9.6 Bank’s Liability for Collateral. So long as Bank complies with reasonable banking practices and the Code regarding the
safekeeping of the Collateral in the possession or under the control of Bank, Bank shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the
value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person. Borrower bears all risk of loss, damage or destruction of the Collateral. 

  
 -13-

 9.7 No Waiver; Remedies Cumulative. Bank’s failure, at any time or times, to
require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Bank thereafter to demand strict performance and compliance herewith or therewith. No waiver
hereunder shall be effective unless signed by Bank and then is only effective for the specific instance and purpose for which it is given. Bank’s rights and remedies under this Agreement and the other Loan Documents are cumulative. Bank has all
rights and remedies provided under the Code, by law, or in equity. Bank’s exercise of one right or remedy is not an election, and Bank’s waiver of any Event of Default is not a continuing waiver. Bank’s delay in exercising any remedy
is not a waiver, election, or acquiescence. 
 9.8 Demand Waiver. Except as expressly provided for herein or in any other
Loan Document, Borrower waives demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments,
chattel paper, and guarantees held by Bank on which Borrower is liable. 
  

	10.	NOTICES

	11.	CHOICE OF LAW, VENUE, JURY TRIAL WAIVER AND JUDICIAL REFERENCE 

 California law governs the Loan Documents without regard to principles of conflicts of law. Borrower and Bank each submit to the exclusive jurisdiction of the State and Federal courts in Santa Clara
County, California; provided, however, that nothing in this Agreement shall be deemed to operate to preclude Bank from bringing suit or taking other legal action in any other jurisdiction to realize on the Collateral or any other security for the
Obligations, or to enforce a judgment or other court order in favor of Bank. Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it
may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court. Borrower hereby waives personal service of the
summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in Section 10
of this Agreement and that service so made shall be deemed completed upon the earlier to occur of Borrower’s actual receipt thereof or three (3) days after deposit in the U.S. mails, proper postage prepaid. 

  
 -14-

 TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER AND BANK EACH WAIVE THEIR
RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS. THIS WAIVER IS A MATERIAL
INDUCEMENT FOR BOTH PARTIES TO ENTER INTO THIS AGREEMENT. EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL. 
 WITHOUT
INTENDING IN ANY WAY TO LIMIT THE PARTIES’ AGREEMENT TO WAIVE THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY, if the above waiver of the right to a trial by jury is not enforceable, the parties hereto agree that any and all disputes or controversies
of any nature between them arising at any time shall be decided by a reference to a private judge, mutually selected by the parties (or, if they cannot agree, by the Presiding Judge of the Santa Clara County, California Superior Court) appointed in
accordance with California Code of Civil Procedure Section 638 (or pursuant to comparable provisions of federal law if the dispute falls within the exclusive jurisdiction of the federal courts), sitting without a jury, in Santa Clara County,
California; and the parties hereby submit to the jurisdiction of such court. The reference proceedings shall be conducted pursuant to and in accordance with the provisions of California Code of Civil Procedure §§ 638 through 645.1,
inclusive. The private judge shall have the power, among others, to grant provisional relief, including without limitation, entering temporary restraining orders, issuing preliminary and permanent injunctions and appointing receivers. All such
proceedings shall be closed to the public and confidential and all records relating thereto shall be permanently sealed. If during the course of any dispute, a party desires to seek provisional relief, but a judge has not been appointed at that
point pursuant to the judicial reference procedures, then such party may apply to the Santa Clara County, California Superior Court for such relief. The proceeding before the private judge shall be conducted in the same manner as it would be before
a court under the rules of evidence applicable to judicial proceedings. The parties shall be entitled to discovery which shall be conducted in the same manner as it would be before a court under the rules of discovery applicable to judicial
proceedings. The private judge shall oversee discovery and may enforce all discovery rules and order applicable to judicial proceedings in the same manner as a trial court judge. The parties agree that the selected or appointed private judge shall
have the power to decide all issues in the action or proceeding, whether of fact or of law, and shall report a statement of decision thereon pursuant to the California Code of Civil Procedure § 644(a). Nothing in this paragraph shall limit the
right of any party at any time to exercise self-help remedies, foreclose against collateral, or obtain provisional remedies. The private judge shall also determine all issues relating to the applicability, interpretation, and enforceability of this
paragraph. 
  

	12.	GENERAL PROVISIONS 

12.1 Successors and Assigns. This Agreement binds and is for the benefit of the successors and permitted assigns of each party.
Borrower may not assign this Agreement or any rights or obligations under it without Bank’s prior written consent (which may be granted or withheld in Bank’s discretion). Bank has the right, without the consent of or notice to Borrower, to
sell, transfer, negotiate, or grant participation in all or any part of, or any interest in, Bank’s obligations, rights, and benefits under this Agreement and the other Loan Documents. 

12.2 Indemnification. Borrower agrees to indemnify, defend and hold Bank and its directors, officers, employees, agents,
attorneys, or any other Person affiliated with or representing Bank harmless against: (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with the transactions
contemplated by the Loan Documents; and (b) all losses or Bank Expenses incurred, or paid by Bank from, following, or arising from transactions between Bank and Borrower (including reasonable attorneys’ fees and expenses), except for
Claims and/or losses directly caused by Bank’s gross negligence or willful misconduct. 
 12.3 Time of Essence. Time
is of the essence for the performance of all Obligations in this Agreement. 
 12.4 Severability of Provisions. Each
provision of this Agreement is severable from every other provision in determining the enforceability of any provision. 

12.5 Amendments in Writing; Integration. All amendments to this Agreement must be in writing signed by both Bank and Borrower.
This Agreement and the Loan Documents amend and restate the terms of the Original Agreement, without novation, and represent the entire agreement about this subject matter and supersede 

  
 -15-

 
prior negotiations or agreements. All prior agreements, understandings, representations, warranties, and negotiations between the parties about the subject matter of this Agreement and the Loan
Documents merge into this Agreement and the Loan Documents. 
 12.6 Counterparts. This Agreement may be executed in any
number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, are an original, and all taken together, constitute one Agreement. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy or electronic copy shall be effective as delivery of a manually executed counterpart of this Agreement. 

12.7 Survival. All covenants, representations and warranties made in this Agreement continue in full force until this Agreement
has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations, Obligations with respect to Bank Services, and any other obligations which, by their terms, are to survive the termination of this Agreement) have
been paid in full and satisfied. Without limiting the foregoing, except as otherwise provided in Section 4.1, the grant of security interest by Borrower in Section 4.1 shall survive until the termination of all Bank Services Agreements.
The obligation of Borrower in Section 12.2 to indemnify Bank, and Bank’s obligations under Section 12.8 (Confidentiality) shall survive until the statute of limitations with respect to such claim or cause of action shall have run.

 12.8 Confidentiality. In handling any confidential information, Bank and all employees and agents of Bank shall
exercise the same degree of care that it exercises for its own proprietary information, but disclosure of information may be made: (a) to Bank’s Subsidiaries or Affiliates in connection with their present or prospective business relations
with Borrower (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such information and instructed to keep such information confidential in accordance with this Section 12.8);
(b) to prospective transferees or purchasers of any interest in the Credit Extensions (provided that they have entered into a comparable confidentiality agreement in favor of Borrower to which Borrower is a party or pursuant to which Borrower
and its Subsidiaries are third party beneficiaries); (c) as required by law, regulation, subpoena, or other order; (d) to Bank’s regulators or as otherwise required in connection with Bank’s examination or audit; and (e) as
Bank considers appropriate in exercising remedies under this Agreement at any time during the existence of an Event of Default. Confidential information does not include information that either: (i) is in the public domain or in Bank’s
possession when disclosed to Bank, or becomes part of the public domain after disclosure to Bank through no fault of Bank; or (ii) is disclosed to Bank by a third party on a non-confidential basis other than as a result of this
Section 12.8, if Bank does not know that the third party is prohibited from disclosing the information. Should Bank be required to disclose any such information by virtue of a subpoena or similar process by any court, tribunal, or agency
pursuant to items (c), (d) or (e) above, then Bank shall use commercially reasonable efforts to promptly notify Borrower thereof so as to allow Borrower, at its sole cost and expense, to seek a protective order or to take any other
appropriate action to protect its rights. 
 12.9 Attorneys’ Fees, Costs and Expenses. In any action or proceeding
between Borrower and Bank arising out of or relating to the Loan Documents, the prevailing party shall be entitled to recover its reasonable attorneys’ fees and other costs and expenses incurred, in addition to any other relief to which it may
be entitled. 
 12.10 Additional Covenants of Bank in connection with Patriot Financing. In the event that Patriot
obtains financing from one or more banks, financial institutions or other lending entities (collectively, the “Patriot Lenders”), then Bank agrees, if requested by the Patriot Lenders or any agent acting on their behalf: (a) to

 Matt Micheli

 Cheyenne, WY 82007 

Matt, 
 I am very pleased
to offer you the position of Corporate Counsel for Luca Technologies Inc. (the “Company”) at the rate of $17,500.00 a month. Your employment will begin January 10th, 2011 and be located at the Company’s offices in Golden, Colorado. Additionally, you will be eligible for the
employee benefit programs generally available to employees of the Company, including twenty-six (26) days of Personal Time Off (“PTO”) in accordance with the Company’s PTO policy. In addition, subject to approval by the
Company’s Board of Directors, the Company will grant you an option to purchase 75,000 shares of the Company’s Common Stock, vesting over four years (18,750 shares vesting after the first year and then monthly vesting thereafter), at an
exercise price equal to the fair market value of the Company’s Common Stock on the date of grant. 
 Additionally, the Company will either
(a) provide you with a housing allowance of $1,000 per month or (b) reimburse your actual hotel costs for the month associated with overnight accommodations approved by the Company, whichever you prefer, for the period of time (not to
exceed six months) prior to your permanent relocation, and the Company will reimburse you for up to $10,000 in relocation expenses for your move from Cheyenne to the Denver area. 
 Finally, the Company agrees to pay you 90 days of severance for an “Involuntary Termination”, as that term is defined in the Company’s Third Amended and Restated 2007 Equity Incentive Plan
(unless another severance arrangement is agreed to by you and the Company subsequent to your employment date) after you have signed (and not revoked) the Company’s standard Severance Agreement and General Release and Waiver of Claims.

 Please be advised that nothing in this offer letter, or any other policy, practice, procedure or benefit constitutes an express or implied
contract, guarantee, promise, or covenant of employment. The employment relationship at the Company is at-will, meaning you and the Company may terminate this relationship at any time without notice, cause, or disciplinary procedures. This offer of
employment is conditioned upon your successful completion of a drug screen, Background check, verification of your eligibility to work in the United States and your signing the “Employee Proprietary Information and Inventions Agreement”
and the “Acknowledgement of Receipt” relating to the Company’s Employee Policy Guide. 
 By your signature below, you acknowledge
that this offer letter, the “Employee Proprietary Information and Inventions Agreement” and the “Acknowledgement of Receipt” constitute the full understanding between you and the Company regarding your terms and conditions of

 
employment, and that you agree to devote your full-time business activities to the Company. There are no promises, terms, conditions, or obligations other than those contained herein, and this
offer letter supersedes and replaces all previous communication, representations, verbal or written, between the parties. The terms of this offer may only be changed by written agreement, although the Company may from time to time, in its sole
discretion, adjust the salaries and benefits paid to you and its other employees, as well as reporting relationships, job titles and responsibilities, and other Company policies. 
 Please review this letter and, if it is acceptable, sign and return it to me indicating that you agree to the terms of this offer. We look forward to hearing from you. 

If I may be of assistance to you, please contact me directly at (303) 597-8218. 
 Sincerely,
