A Transfer (a “Permitted Transfer”) to a Permitted Transferee by a Stockholder (such Stockholder, the “Permitted Transferor”) shall be valid only upon execution by such Permitted Transferee of an agreement, reasonably acceptable to the Company, to be bound by and subject to the terms of this Agreement as applicable to the Permitted Transferor. Upon execution and delivery of such agreement, the Permitted Transferee shall be deemed to be party hereto as if such Permitted Transferee were the Permitted Transferor, and such Permitted Transferee’s signature appeared on the signature pages of this Agreement, and the references in this Agreement to the Permitted Transferor shall be deemed to apply to the Permitted Transferee; provided, however, that such Permitted Transfer shall not relieve the Permitted Transferor of obligation or liability under this Agreement. (b) Any purported Transfer in violation of this Section 3 shall be deemed to cause irreparable harm to the other Parties. (c) It is recognized that damages may not be an appropriate remedy for breach of this Section 3 and, accordingly, the Parties hereto acknowledge that, in addition to any other rights and remedies provided for in this Agreement, injunctive or other equitable relief will be the appropriate remedy to deal with any breach of this Section 3. 3.02 Change of Control of Investor; Effect of Being a Competitor. A change of control of a Stockholder’s ultimate parent entity shall not be a Transfer for purposes of Section 3.01; however, in the event that all of the Board, excluding the applicable designee(s), reasonably determines that a Stockholder is, or is beneficially owned by, or otherwise an Affiliate of, a Competitor, such Stockholder shall, promptly following any such determination by the Board, (i) not be entitled to any inspection rights, (ii) be deemed to have waived all inspection and information rights afforded to stockholders under the Delaware General Corporation Law or hereunder and (iii) cause any director or observer designated by such Stockholder to resign; provided, however, that following such resignation, such Stockholder may designate a director pursuant to Section 2.03 hereto who shall be sufficiently independent (as decided by the Board) from such Stockholder as to present a de minimis risk of sharing confidential technical information of the Company (such designee, a “Stockholder Independent Director”). As a condition to the Stockholder Independent Director joining the Board, such Stockholder Independent Director, the Company, and the Stockholder designating such Stockholder Independent Director shall execute a non-disclosure agreement, in a form to be agreed by the Company, the Stockholder Independent Director, and such Stockholder, that shall restrict and limit the Stockholder Independent Director’s ability to share confidential technical information of the Company with such Stockholder. Such restrictions (not including the confidentiality and non-disclosure restrictions) shall terminate upon Transfer of the Stockholder’s shares of Stockholder Shares to a third party approved by the Board. 3.03 Notice of Transfer. If a Stockholder (the “Selling Stockholder”) receives from a third party (the “Third Party”) a bona fide written offer (the “Third Party Offer”) regarding the direct or indirect Transfer of any Stockholder Shares, then the Selling Stockholder shall only accept such Third Party Offer subject to compliance with the provisions of this Section 3. Upon such conditional acceptance, the Selling Stockholder shall deliver notice in writing (“Notice of Transfer”) to the Company and each of the Major Investors irrevocably offering to sell first to the Company, in accordance with Section 3.04, and then to the Major Investors, in accordance with Section 3.05, that certain number of Stockholder Shares that are the subject of the Third Party Offer (the “Transfer Stock”) at the same price and on the same terms and conditions as provided in the Third Party Offer and such offer to sell shall remain open for acceptance for the periods specified in Section 3.04 and Section 3.05. The Selling Stockholder shall deliver, with the Notice of Transfer, a true copy of the Third Party Offer, including a description of the nature of such Transfer, the consideration to be paid, the name and address of the Third Party and, if the Third Party is not an individual, the names of the principal shareholders or holders of interests in such Third Party (if

14 available), officers and directors (or the equivalent) of the Third Party and any other information with respect to the financial capacity of the Third Party in the possession of the Selling Stockholder. Notwithstanding the foregoing, the provisions of this Section 3.03 shall not apply to a Transfer to a Permitted Transferee. 3.04 Company Right of First Refusal. For a period of twenty (20) days following receipt of the Notice of Transfer described in Section 3.03, the Company shall have the right to purchase all or a portion of the Transfer Stock subject to such Notice of Transfer on the same terms and conditions as set forth therein. The Company’s purchase right shall be exercised by written notice signed by an officer of the Company (the “Company Notice”) and delivered to the Selling Stockholder within such twenty (20) day period. The Company shall effect the purchase of the Transfer Stock, including payment of the purchase price, not more than five (5) Business Days after delivery of the Company Notice, and at such time the Selling Stockholder shall deliver to the Company a duly executed transfer signed by the Selling Stockholder and representing the Transfer Stock to be purchased by the Company. The Transfer Stock so purchased shall thereupon be cancelled and cease to be issued and outstanding shares of the Company’s stock. 3.05 Stockholder Right of First Refusal. (a) In the event that the Company does not elect to purchase all of the Transfer Stock available pursuant to its rights under Section 3.04 within the period set forth therein, the Selling Stockholder shall promptly give written notice (the “Second Notice”) to each of the Major Investors (each Major Investor other than the Company being a “ROFR Party”), which shall set forth the number of shares of Transfer Stock not purchased by the Company and which shall include the terms of Notice of Transfer set forth in Section 3.03. Each ROFR Party shall then have the right, exercisable upon written notice to the Selling Stockholder within twenty (20) days after the receipt of the Second Notice, to purchase all or any portion, of its pro rata share of the Transfer Stock subject to the Second Notice and on the same terms and conditions as set forth therein. Except as set forth in Section 3.05(c), the ROFR Parties who so exercise their rights (the “Participating Parties”) shall effect the purchase of the Transfer Stock, including payment of the purchase price, on the same terms and conditions as the Third Party Offer, and at such time the Selling Stockholder shall deliver to the Participating Parties a duly executed certificate representing the Transfer Stock to be purchased by the Participating Parties, each certificate to be properly endorsed for transfer. In the event there are no Participating Parties, the Selling Stockholder may sell the Transfer Stock not purchased by the Company pursuant to Section 3.04 to the Third Party on the terms and conditions as set forth in the Third Party Offer. (b) Each ROFR Party’s pro rata share shall be equal to the product obtained by multiplying (i) the aggregate number of shares of Transfer Stock covered by the Second Notice and (ii) a fraction, the numerator of which is the number of Stockholder Shares issued or other rights to acquire Stockholder Shares held by the Participating Party at the time of the Notice of Transfer, and the denominator of which is the total number of Stockholder Shares issued or other rights to acquire Stockholder Shares at the time of the Notice of Transfer held by all Participating Parties. (c) In the event that not all of the ROFR Parties elect to purchase their pro rata share of the Transfer Stock available pursuant to their rights under Section 3.05(a) within the time period set forth therein, then the Selling Stockholder shall promptly give written notice to each of the Participating Parties (the “Overallotment Notice”), which shall set forth the number of shares of Transfer Stock not purchased by the other ROFR Parties, and shall offer such Participating Parties the right to acquire such unsubscribed shares. Each Participating Party shall have five (5) Business Days after receipt of the Overallotment Notice to deliver a written notice to the Selling Stockholder (the “Participating Parties’ Overallotment Notice”) indicating the number of unsubscribed shares that such Participating Party desires to purchase, and each such Participating Party shall be entitled to purchase such number of unsubscribed shares on the same terms

15 and conditions as set forth in the Second Notice. In the event that the Participating Parties desire, in the aggregate, to purchase in excess of the total number of available unsubscribed shares, then the number of unsubscribed shares that each Participating Party may purchase shall be reduced on a pro rata basis. For purposes of this Section 3.05(c) the denominator described in clause (ii) of Section 3.05(b) above shall be the total number of Stockholder Shares issued or other rights to acquire Stockholder Shares held by the Participating Party at the time of the Notice of Transfer. The Participating Parties shall then effect the purchase of the Transfer Stock, including payment of the purchase price, not more than five (5) Business Days after delivery of the Participating Parties’ Overallotment Notice. 3.06 Security Option. (i) If the Parties (other than the Party at question) make a good faith reasonable determination that the creditworthiness of any other Party (other than the Company) is such that such other Party will be unable to meet its ongoing obligations (which determination must be based on objective circumstances that are materially adverse to such other Party), or (ii) in the event of the liquidation, dissolution or winding-up of any Party (other than the Company) (in each case, an “Affected Party”), then the other Parties shall have the option (the “Triggered Security Option”) to require the Affected Party to grant a first priority security interest in such Affected Party’s Stockholder Shares, securing such Party’s obligations under the Transaction Agreements. Exercise of the Triggered Security Option shall not be subject to the terms of Section 3.01 or Section 3.03 of this Agreement. 4. Prohibited Transfers. 4.01 Call Option Upon Prohibited Transfer. In the event of a prohibited Transfer in violation of Section 3 hereof (a “Prohibited Transaction”), the other Parties shall have the option to purchase from the pledgee, purchaser or transferee of the Transfer Stock transferred in violation of Section 3, the number of shares that such Party would have been entitled to purchase had such Prohibited Transaction been effected in accordance with Section 3 hereof, on the following terms and conditions (with the Company having the first right to exercise such right, followed by the other Parties (other than the Selling Stockholder)): (a) The price per share at which the shares are to be purchased by the other Parties shall be equal to the price per share paid to such Stockholder by the third party purchaser or purchasers of such Transfer Stock that is subject to the Prohibited Transaction; and (b) the Stockholder effecting such Prohibited Transaction shall reimburse the other Parties for any expenses, including legal fees and expenses, incurred in effecting such purchase. 4.02 Voidability of Transfer. Notwithstanding the foregoing, any purported Transfer by a Stockholder of Transfer Stock (or portion thereof) in violation of Section 3 hereof shall be voidable at the option of the holders of a majority of the Transfer Stock not held by the Selling Stockholder if such majority of the Stockholders (other than the Selling Stockholder) do not elect to exercise the call set forth in this Section 4, and the Company agrees it will not effect such Transfer nor will it treat any alleged transferee as the holder of such shares without the written consent of such majority of the Stockholders (other than the Selling Stockholder). 5. Issue of Additional Securities. 5.01 First Offer to Major Investors. Except as provided in Section 5.03, if any Additional Securities are to be issued, the Company shall first offer such Additional Securities to the Major Investors by notice given to them of the Company’s intention to issue Additional Securities, the number of such Additional Securities to be issued and the terms and conditions of such Additional Securities and the terms and conditions of the offer.

16 5.02 Issuance of Additional Securities. Each of the Major Investors shall have the right to purchase the Additional Securities so offered pro rata based upon the number of Stockholder Shares beneficially owned by all such Major Investors at the date notice is given of such offer. Each of the Major Investors shall have 20 days from the date such notice is given to give a notice to the Company of its intention to purchase all or any of the Additional Securities to which it is entitled and shall indicate in such notice the maximum number of Additional Securities which it is willing to purchase (which number may be greater than or less than its pro rata entitlement). If any Major Investor does not accept its pro rata entitlement, such unaccepted Additional Securities shall be deemed to have been offered to the Major Investors, as applicable, who indicated they would accept greater than their pro rata entitlement and each such Major Investor, as applicable, shall be entitled to acquire such unaccepted Additional Securities pro rata based upon the number of Stockholder Shares beneficially owned by all such Major Investors. The transaction of purchase and sale by the Company to the Major Investors, as applicable, shall be completed on the date specified by the Board. Any Additional Securities not accepted by the Major Investors, as applicable, may be issued within two months of such Additional Securities having been first offered to the Major Investors, as applicable, at not less than the price offered to the Major Investors, to such Persons as the Board determines, provided that such persons execute and deliver a joinder agreement to this Agreement substantially in the form attached hereto as Exhibit B (the “Joinder Agreement”). 5.03 Exempt Issuances. The Company shall be entitled to issue Additional Securities without complying with the provisions of Section 5.01, when such Additional Securities are being issued: (a) to any eligible optionees pursuant to the Equity Incentive Plan or other similar arrangements adopted and approved by the Board; (b) upon the exercise of conversion or exchange rights attached to any equity securities of the Company pursuant to the terms of the Equity Incentive Plan or other similar arrangements adopted and approved by the Board; (c) to LanzaTech pursuant to Section 4.01 of the Investment Agreement; (d) to any Lender pursuant to Section 5.01 of the Investment Agreement; and (e) to any Person upon the exercise of any outstanding securities or other instruments that, when issued, were duly authorized and properly issued by the Company. 6. Registration. “Initial Offering” shall mean an approved firmly underwritten initial public offering and/or the listing for trading of the Company’s securities on a recognized stock exchange in the United States of America or on any other recognized stock exchange. For purpose of this Article 6, with respect to a listing for trading of the Company’s securities on a recognized stock exchange in the United States of America, the following provisions will apply (provided that if the Company undertakes an approved Initial Offering outside of the United States of America, the following rights will be modified as and to the extent necessary to comply with the relevant jurisdiction). For purposes of this Section 6, “Registrable Securities” shall mean (i) Common Stock of the Company issuable or issued to the Stockholders, (ii) any Common Stock of the Company issued or issuable (directly or indirectly) upon conversion and/or exercise of any other securities of the Company, acquired by the Investors after the date hereof or (iii) any Common Stock of the Company issued as (or issuable upon the conversion or exercise of any warrant, right or other security which is issued as) a dividend or other distribution with respect to, or in exchange for or in replacement of, such above-described securities in clauses (i)-(iii). Notwithstanding the foregoing, Registrable Securities shall not include any securities (x) for which registration rights have terminated pursuant to Section 6.13 or

17 (y) sold in a private transaction in which the transferor’s rights under Section 5 of this Agreement are not assigned. For purposes of this Article 6, “Registrable Securities then outstanding” shall mean the number of shares determined by adding the number of shares of outstanding Common Stock that are Registrable Securities and the number of shares of Common Stock issuable (directly or indirectly) pursuant to then exercisable and/or convertible securities that are Registrable Securities. 6.01 Demand Registration. (a) Subject to the conditions of this Section 6.01, and following the end of the Company’s lock-up period with the underwriters of the Initial Offering in connection with the Company’s consummation of an Initial Offering (provided that if there are no underwriters or lock-up, this will be triggered upon the consummation of an Initial Offering), if the Company shall receive a written request from any person or group of persons beneficially owning, owning of record or having the right to acquire Registrable Securities that have not been sold to the public or any assignee of record of such Registrable Securities in accordance with Section 6.09 hereof (each, a “Holder”) of 10% of the Registrable Securities then outstanding (the “Initiating Holders”) that the Company file a registration statement on Form S-1 or Form F-1 under the United States Securities Act of 1933, as amended (the “Securities Act”) or another offering document pursuant to any other applicable Laws and regulations (collectively, the “Applicable Listing Laws and Regulations”) covering the registration of at least such number of the Registrable Securities having an anticipated aggregate offering price, net of all underwriting discounts and selling commissions applicable to the sale (“Selling Expenses”), of at least fifteen million dollars (US $15,000,000), then the Company shall, within ten (10) days of the receipt thereof, give written notice of such request to all Holders (the “Demand Notice”), and subject to the limitations of this Section 6.01, (x) as soon as practicable, and in any event within sixty (60) days after the date of such request is given by the Initiating Holders, file a Form S-1 or F-1 registration statement under the Securities Act registering all Registration Securities that the Initiating Holders requested to be registered and any additional Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within twenty (20) days of the date the Demand Notice and (y) effect, as expeditiously as reasonably possible, the registration under the Securities Act or any other Applicable Listing Laws and Regulations of all Registrable Securities that all Holders request to be registered. (b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 6.01 or any request pursuant to Section 6.04 and the Company shall include such information in the written notice referred to in Section 6.01(a) or Section 6.04(a), as applicable. In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Holders of a majority of the Registrable Securities then outstanding held by all Initiating Holders (which underwriter or underwriters shall be reasonably acceptable to the Company). Notwithstanding any other provision of this Section 6.01 or Section 6.04, if the underwriter advises the Company that marketing factors require a limitation of the number of securities to be underwritten (including Registrable Securities) then the Company shall so advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be allocated to the Holders of such Registrable Securities on a pro rata basis based on the number of Registrable Securities held by all such Holders (including the Initiating Holders). For purposes of Section 6.01(c)(i), a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in this Section 6.01(b), fewer than all of the Registrable Securities that Holders have requested to be included in such registration statement are actually included.

18 (c) The Company shall not be required to effect a registration pursuant to this Section 6.01: (i) after the Company has effected two (2) registrations pursuant to this Section 6.01, and such registrations have been declared or ordered effective; provided, that, a registration shall not be counted as “effected” for purposes of this Section 6.01 until such time as the applicable registration statement has been declared effective by the SEC or any other Listing Authority, unless the Initiating Holders withdraw their request for such registration, elect not to pay the registration expenses therefor, and forfeit their right to one demand registration statement, in which case such withdrawn registration statement shall be counted as “effected” for purposes of this Section 6.01; provided, further, that if such withdrawal is made as a result of a material adverse change to the Company, then the Initiating Holders may withdraw their request for registration and such registration will not be counted as “effected” for purposes of this Section 6.01. (ii) during the period starting with the date of filing of, and ending at the end of the Company’s lock-up period with the underwriters of the Initial Offering in connection with the Company’s consummation of an Initial Offering (provided that if there are no underwriters or lock-up, this period will end upon the effectiveness of the registration statement or other offering document pertaining to the Initial Offering); provided that the Company makes reasonable good faith efforts to cause such registration statement or other offering document to become effective; (iii) if within thirty (30) days of receipt of a written request from Initiating Holders pursuant to Section 6.01(a), the Company gives notice to the Holders of the Company’s intention to file a registration statement or other offering document for its Initial Offering within ninety (90) days; provided, however, that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective during such ninety (90) day period; (iv) if the Company shall furnish to Holders requesting a registration statement or other offering document pursuant to this Section 6.01 a certificate signed by the chairperson of the Board stating that in the good faith judgment of the Board, it would be materially detrimental to the Company and its stockholders for such registration statement or other offering document to be effected at such time because it would (i) materially interfere with a significant acquisition, corporate reorganization or other similar transaction involving the company, (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential, or (iii) render the Company unable to comply with requirements under the Securities Act or Exchange Act, in which event the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the Initiating Holders; provided that such right to delay a request shall be exercised by the Company not more than once in any twelve (12) month period and provided that the Company shall not register any other of its shares during such 90-day period; (v) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 or Form F-3 pursuant to a request made pursuant to Section 6.04 below; or (vi) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. 6.02 Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in writing at least ten (10) days prior to the filing or confidential submission of any registration statement

19 under the Securities Act or another offering document pursuant to any other Applicable Listing Laws and Regulations for purposes of a public offering of securities of the Company (including, but not limited to, registration statements or other offering documents relating to the Initial Offering or any secondary offerings of securities of the Company, but excluding (i) a registration statement relating to any employee benefit plan, (ii) with respect to any corporate reorganization or transaction under Rule 145 of the Securities Act, any registration statements related to the issuance or resale of securities issued in such a transaction or (iii) a registration related to stock issued upon conversion of debt securities (together, the “Special Registration Statements”)) and will afford each such Holder an opportunity to include in such registration statement all or part of such Registrable Securities held by such Holder. Each Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by it shall, within fifteen (15) days after the above-described notice from the Company, so notify the Company in writing. Such notice shall state the intended method of disposition of the Registrable Securities by such Holder. If a Holder decides not to include any or all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration statements or other offering document as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein. Additionally, no stockholder of the Company shall be granted piggyback registration rights which would reduce the number of shares includable by the Holders of the Registrable Securities in such registration without the consent of the Holders of a majority of the Registrable Securities then outstanding. 6.03 Underwriting. If the registration statement or other offering document of which the Company gives notice under Section 6.02 is for an underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to include Registrable Securities in a registration pursuant to Section 6.02 shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by the Company. Notwithstanding any other provision of this Agreement, if the underwriter determines in good faith that marketing factors require a limitation of the number of shares to be underwritten, the number of shares that may be included in the underwriting shall be allocated, first, to the Company; second, to the Holders on a pro rata basis based on the total number of Registrable Securities held by the Holders; and third, to any stockholder of the Company (other than a Holder) on a pro rata basis; provided, however, that no such reduction shall reduce the amount of securities of the selling Holders included in the registration below twenty-five percent (25%) of the total amount of securities included in such registration, unless such offering is the Initial Offering and such registration does not include shares of any other selling stockholders, in which event any or all of the Registrable Securities of the Holders may be excluded in accordance with the immediately preceding clause. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written notice to the Company and the underwriter, delivered at least ten (10) Business Days prior to the effective date of the registration statement or other offering document; provided, however, such Holder’s obligation to provide such notice to the Company and the underwriter is conditioned upon the Company and the underwriter providing written notice of the terms of such underwriting to the Holders twelve (12) Business Days prior to the effective date of the registration statement or other offering document. If it is impracticable for such terms to be provided to the Holder twelve (12) Business Days prior to the effective date of the registration statement or other offering document, then the Holder shall have the right to elect to withdraw from such underwriting during the two (2) Business Day period following the provision of such terms in writing to the Holder. Any Registrable Securities excluded or withdrawn from such underwriting as a result of the prior two sentences shall be excluded and withdrawn from the registration. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners, members, retired members and stockholders of such Holder, or the estates and family members of any such partners, retired partners, members, retired members and stockholders and any trusts for the

20 benefit of any of the foregoing person shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence. The Company shall have the right to terminate or withdraw any registration initiated by it under Section 6.02 whether or not any Holder has elected to include securities in such registration, and shall promptly notify any Holder that has elected to include shares in such registration of such termination or withdrawal. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 6 hereof. Such withdrawn registration shall not be counted as “effected” for purposes of Section 6.01(c)(i) or 6.04(c)(iv). 6.04 Form S-3 or Form F-3 Registration. In case the Company shall receive from any Holder or Holders of Registrable Securities a written request or requests that the Company effect a registration on Form S-3 or Form F-3 (or any successor to Form S-3 or Form F-3) or any similar short-form registration statement and any related qualification or compliance (a “Short Form Registration”) with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company will: (a) promptly, and in any event, within ten (10) days of the receipt of such request, give written notice of the proposed registration, and any related qualification or compliance, to all other Holders of Registrable Securities; (b) as soon as practicable, and in any event within forty-five (45) days after the date such request is given by the requesting Holder, file the Short Form Registration requested by such Holders covering all Registrable Securities requested to be included in such registration by any other Holders; (c) as soon as practicable effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 6.04: (i) if no Short Form Registration is available for such offering by the Holders; (ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than five million dollars (US $5,000,000); (iii) if within thirty (30) days of receipt of a written request from any Holder or Holders pursuant to this Section 6.04, the Company gives notice to such Holder or Holders of the Company’s intention to make a public offering within ninety (90) days, other than pursuant to a Special Registration Statement; provided, however, that the Company shall not utilize this right more than once in any twelve (12) month period, and provided further, that the Company shall not register any other of its shares during such 90-day period other than pursuant to a Special Registration Statement; (iv) if the Company shall furnish to the Holders a certificate signed by the chairperson of the Board stating that in the good faith judgment of the Board, it would be materially detrimental to the Company and its stockholders for such Form S-3 or Form F-3 registration to be effected at such time because it would (i) materially interfere with a significant acquisition, corporate reorganization or other similar transaction involving the company, require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential, or (iii) render the

21 Company unable to comply with requirements under the Securities Act or Exchange Act, in which event the Company shall have the right to defer the filing of the Form S-3 or Form F-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Section 6.04; provided that such right to delay a request shall be exercised by the Company not more than once in any twelve (12) month period and provided that the Company shall not register any other of its shares during such 90-day period other than pursuant to a Special Registration Statement; (v) if the Company has, within the twelve (12) month period preceding the date of such request, already effected two (2) registrations on Form S-3 or Form F-3 for the Holders pursuant to this Section 6.04; or (vi) in any particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act or any other Applicable Listing Laws and Regulations; and (d) Subject to the foregoing, the Company shall file a Form S-3 or Form F-3 registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the requests of the Holders. Registrations effected pursuant to this Section 6.04 shall not be counted as demands for registration pursuant to 6.01 or registrations effected pursuant to Section 6.02. 6.05 Expenses of Registration. Except as specifically provided herein, all expenses (other than Selling Expenses) incurred in connection with any registration, qualification or compliance pursuant to Section 6.01, 6.02 or 6.04 herein shall be borne by the Company, including the reasonable fees and disbursement, of one counsel for the selling Holders (the “Registration Expenses”). All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by the holders of the securities so registered pro rata on the basis of the number of shares so registered. The Company shall not, however, be required to pay for expenses of any registration proceeding begun pursuant to Section 6.01 or 6.04, the request of which has been subsequently withdrawn by the Initiating Holders unless (a) the withdrawal is based upon material adverse information concerning the Company of which the Initiating Holders were not aware at the time of such request or (b) the Holders of a majority of Registrable Securities then outstanding agree to deem such registration to have been effected as of the date of such withdrawal for purposes of determining whether the Company shall be obligated pursuant to Section 6.01(c) or 6.04(c)(v), as applicable, to undertake any subsequent registration, in which event such right shall be forfeited by all Holders. If the Holders are required to pay the Registration Expenses, such expenses shall be borne by the holders of securities (including Registrable Securities) requesting such registration in proportion to the number of shares for which registration was requested. If the Company is required to pay the Registration Expenses of a withdrawn offering pursuant to clause (a) above, then such registration shall not be deemed to have been effected for purposes of determining whether the Company shall be obligated pursuant to Section 6.01(c) or 6.04(c)(v), as applicable, to undertake any subsequent registration. 6.06 Obligations of the Company. Whenever required to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: (a) Prepare and file with the SEC or any listing, governmental or exchange authority or other administrative entity (“Listing Authority”) such registration statement or other offering document requested by the Holders with respect to such Registrable Securities and use all reasonable efforts to cause such registration statement or other offering document to promptly become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement or other offering document effective for up to ninety (90) days or, if earlier, until the Holder or

22 Holders have completed the distribution related thereto; provided, however, (i) that at any time, upon written notice to the participating Holders and for a period not to exceed sixty (60) days thereafter (the “Suspension Period”), the Company may delay the filing or effectiveness of any registration statement or other offering document or suspend the use or effectiveness of any registration statement or other offering document (and the Initiating Holders hereby agree not to offer or sell any Registrable Securities pursuant to such registration statement or other offering document during the Suspension Period) if the Company reasonably believes that there is or may be in existence material nonpublic information or events involving the Company, the failure of which to be disclosed in the prospectus included in the registration statement or other offering document could result in a Violation (as defined below) and (ii) in the case of an registration of Registrable Securities on a Short Form Registration that are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such ninety (90) day period shall be extended for up to an additional two hundred and sixty five (265) days, if necessary, to keep the registration statement effective until all such Registrable Securities are sold. In the event that the Company shall exercise its right to delay or suspend the filing or effectiveness of a registration hereunder, the applicable time period during which the registration statement or other offering document is to remain effective shall be extended by a period of time equal to the duration of the Suspension Period. The Company may extend the Suspension Period for an additional consecutive sixty (60) days with the consent of the holders of a majority of the Registrable Securities to be registered under the applicable registration statement or other offering document, which consent shall not be unreasonably withheld, delayed or conditioned. In no event shall any Suspension Period, when taken together with all prior Suspension Periods, exceed 120 days in the aggregate. If so directed by the Company, all Holders proposing to register shares under such registration statement or other offering document shall not offer to sell any Registrable Securities pursuant to such registration statement or other offering document during the period in which the delay or suspension is in effect after receiving notice of such delay or suspension. (b) Prepare and file with the SEC or any Listing Authority such amendments and supplements to such registration statement and the prospectus, if applicable, or other offering document, used in connection with such registration statement or other offering document as may be necessary to comply with the provisions of the Securities Act, Exchange Act or any other Applicable Listing Laws and Regulations in connection with the listing (on an exchange, foreign or domestic, mutually agreeable to the Company and Holders of a majority of the Registrable Securities then outstanding covered by the registration statement) and the disposition of all securities covered by such registration statement or other offering document for the period set forth in subsection (a) above. (c) Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act or any other Applicable Listing Laws and Regulations and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. (d) Use its reasonable efforts to register and qualify the securities covered by such registration statement or other offering document under such other securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act or any other Applicable Listing Laws and Regulations. (e) In the event of any underwritten public offering, enter into and perform its obligations under an underwriting agreement, in usual and customary form, with the managing underwriter(s) of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

23 (f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus, if applicable, relating thereto is required to be delivered under the Securities Act or any other Applicable Listing Laws and Regulations of the happening of any event as a result of which the prospectus, if applicable, or other offering document, included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. The Company will use reasonable efforts to promptly amend or supplement such prospectus in order to cause such prospectus not to include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. (g) Use its reasonable efforts to furnish, on the date that such Registrable Securities are delivered to the underwriters for sale, if such securities are being sold through underwriters, (i) an opinion and negative assurance disclosure letter, dated as of such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and (ii) a letter, dated as of such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering addressed to the underwriters. (h) Use its commercially reasonable efforts to cause all such Registrable Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed. (i) Provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. (j) Promptly make available for inspection by the selling Holders, any managing underwriter(s) participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith. (k) Notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been declared effective or a supplement to any prospectus forming a part of such registration statement has been filed. (l) After such registration statement becomes effective, notify each selling Holder of any request by the SEC that the Company amend or supplement such registration statement or prospectus. (m) Ensure that, at all times after any registration statement covering a public offering of securities of the Company under the Securities Act shall have become effective, its insider trading policy shall provide that the Company’s directors may implement a trading program under Rule 10b5-1 of the Exchange Act.

24 6.07 Delay of Registration; Furnishing Information. (a) No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 6. (b) It shall be a condition precedent to the obligations of the Company to take any action pursuant to Section 6.01, 6.02 or 6.04 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the intended method of disposition of such securities as shall be required to effect the registration of their Registrable Securities. (c) The Company shall have no obligation with respect to any registration requested pursuant to Section 6.01 or Section 6.04 if the number of shares or the anticipated aggregate offering price of the Registrable Securities to be included in the registration does not equal or exceed the number of shares or the anticipated aggregate offering price required to originally trigger the Company’s obligation to initiate such registration as specified in Section 6.01 or Section 6.04, whichever is applicable. 6.08 Indemnification. In the event any Registrable Securities are included in a registration statement or other offering document under Sections 6.01, 6.02 or 6.04: (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers, directors and stockholders of each Holder, any underwriter (as defined in the Securities Act or any other Applicable Listing Laws and Regulations) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act, other federal or state law or any other Applicable Listing Laws and Regulations, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”) by the Company: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or other offering document or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law, any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law or any other Applicable Listing Laws and Regulations, in connection with the offering covered by such registration statement or other offering document; and the Company will reimburse each such Holder, partner, member, officer, director, stockholder, underwriter or controlling person for any legal or other expenses reasonably incurred (as such expenses are incurred) by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided however, that the indemnity agreement contained in this Section 6.08(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, delayed or conditioned, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, member, officer, director, stockholder, underwriter or controlling person of such Holder. (b) To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if

25 any, who controls the Company within the meaning of the Securities Act or any other Applicable Listing Laws and Regulations, any underwriter and any other Holder selling securities under such registration statement or other offering document or any of such other Holder’s partners, directors or officers or any person who controls such Holder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act other federal or state law or any other Applicable Listing Laws and Regulations, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any of the following statements: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration statement or incorporated reference therein, including any preliminary prospectus or final prospectus contained therein or other offering document or any amendments or supplements thereto or (ii) the omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading (collectively, a “Holder Violation”), in each case to the extent (and only to the extent) that such Holder Violation occurs in reliance upon and in conformity with written information furnished by such Holder under an instrument duly executed by such Holder and stated to be specifically for use in connection with such registration; and each such Holder will reimburse any legal or other expenses reasonably incurred (as such expenses are incurred) by the Company or any such director, officer, controlling person, underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such a Holder Violation; provided, however, that the indemnity agreement contained in this Section 6.08(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld, delayed or conditioned; provided further, that in no event shall any indemnity under this Section 6.08 exceed the net proceeds from the offering received by such Holder. (c) Promptly after receipt by an indemnified party under this Section 6.08 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 6.08, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses thereof to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 6.08 to the extent, and only to the extent, prejudicial to its ability to defend such action, but the omission to so deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 6.08. (d) If the indemnification provided for in this Section 6.08 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of indemnifying such indemnified party thereunder, shall to the extent permitted by applicable Law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the Violation(s) or Holder Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the

26 untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission; provided that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the offering received by such Holder. (e) The obligations of the Company and Holders under this Section 6.08 shall survive completion of any offering of Registrable Securities in a registration statement or other offering document and, with respect to liability arising from an offering to which this Section 6.08 would apply that is covered by a registration filed before termination of this Agreement, such termination. No indemnifying party, in the defense of any such claim, action or litigation, shall, except with the consent of each indemnified party, which consent shall not be unreasonably withheld, delayed or conditioned consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim, action or litigation. 6.09 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 6 may be assigned by a Holder to a transferee or assignee of Registrable Securities (for so long as such shares are Registrable Securities immediately prior to the transfer) that (a) is a subsidiary, parent, general partner, limited partner, retired partner, member or retired member of a Holder that is a corporation, partnership or limited liability company, (b) is a Holder’s family member or trust for the benefit of an individual Holder or trust for the benefit of one or more of such Holder’s family members, or (c) is an entity affiliated by common Control (or other related entity) with such Holder provided, however, that (i) the transferor shall, within ten (10) days after such transfer, furnish to the Company written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned and that (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement. 6.10 “Market Stand-Off” Agreement. In the event of a registration by the Company of shares of its Common Stock under the Securities Act, each Holder hereby agrees that such Holder shall not without the prior written consent of the managing underwriter or the Company (as the case may be) sell, transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, any Common Stock (or other securities) of the Company held by such Holder immediately before the effective date of the registration statement for such offering (other than those included in the registration) during a period not to exceed one hundred eighty (180) days following the effective date of the Initial Offering (or such longer period as the underwriters or the Company shall request in order to facilitate compliance with NASD Rule 2711); provided that all officers and directors of the Company and holders of at least one percent (1%) of the Company’s outstanding voting securities (after giving effect to conversion into voting securities of all securities convertible into voting securities) are bound by and have entered into similar agreements and restrictions. The obligations described in this Section 6.10 shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all Holders subject to such agreements, based on the number of shares subject to such agreements. The Holders agree that if the Company undertakes an approved Initial Offering outside the United States of America, the foregoing rights shall be modified to the extent necessary to comply with the relevant jurisdiction. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of said day period.

27 6.11 Agreement to Furnish Information. Each Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter that are consistent with the Holder’s obligations under Section 6.10 or that are reasonably necessary to give further effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, each Holder shall provide, within ten (10) days of such request, such information as may be required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act or another offering document pursuant to any other Applicable Listing Laws and Regulations. The obligations described in Section 6.10 and this Section 6.11 shall not apply to a Special Registration Statement. Each Holder agrees that any transferee of any shares of Registrable Securities shall be bound by Sections 6.10 and 6.11. The underwriters of the Company’s stock are intended third party beneficiaries of Sections 6.10 and 6.11 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. 6.12 Rule 144 Reporting. With a view to making available to the Holders the benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, the Company agrees to use its best efforts to: (a) Make and keep public information available, as those terms are understood and defined in SEC Rule 144 or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration filed by the Company for an offering of its securities to the general public; (b) File with the SEC, in a timely manner, all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request: a written statement by the Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of the Exchange Act (at any time after it has become subject to such reporting requirements); a copy of the most recent annual or quarterly report of the Company filed with the U.S. Securities and Exchange Commission; and such other reports and documents as a Holder may reasonably request in connection with availing itself of any rule or regulation of the SEC allowing it to sell any such securities without registration. 6.13 Termination of Registration Rights. (a) The right of any Holder to request registration or inclusion of Registrable Securities in any registration pursuant to Section 6.01 or Section 6.04 hereof shall terminate upon the earlier of: (i) the date four (4) years following an initial public offering of the Company’s Common Stock; (ii) upon the consummation of a transaction that qualifies as a “Deemed Liquidation Event” (as such term is defined in the Restated Certificate); or (iii) as to any Holder, such time at which all Registrable Securities held by such Holder (and any Affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) can be sold in any three (3) month period without registration in compliance with Rule 144 of the Securities Act. Upon such termination, such shares shall cease to be “Registrable Securities” hereunder for all purposes. (b) The right of any Holder to request registration or inclusion of Registrable Securities in any registration pursuant to Section 6.02 hereof shall terminate on the date that is two (2) years following the date that the right of such Holder to request registration or inclusion of Registrable Securities

28 in a registration pursuant to Section 6.01 or Section 6.04 hereof terminates pursuant to Section 6.13(a)(ii) hereof. 6.14 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of the Requisite Holders (as defined in the Restated Certificate), enter into any agreement with any holder or prospective holder of any securities of the Company that would (i) allow such holder or prospective holder to include such securities in any registration unless, under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent that the inclusion of such securities will not reduce the number of the Registrable Securities of the Holders that are included; or (ii) allow such holder or prospective holder to initiate a demand for registration of any securities held by such holder or prospective holder; provided that this limitation shall not apply to Registrable Securities acquired by any additional Investor that becomes a party to this Agreement in accordance with Section 5.02 and Section 11.12. 6.15 Survival of Covenants. Subject to the limitations provided in this Section 6, the obligations set forth in this Section 6 shall be continuing and survive the termination of this Agreement pursuant to an Initial Offering. 7. Covenants of the Company. 7.01 Delivery of Financial Information and Reporting.

(b) The Company will furnish to each Major Investor: (i) as soon as practicable after the end of each fiscal year of the Company, and in any event within one hundred twenty (120) days thereafter, an audited income statement for such fiscal year, a balance sheet of the Company and statement of stockholder’s equity as of the end of such year, and a statement of cash flows for such year, such year-end financial reports to be in reasonable detail, prepared in accordance with United States generally accepted accounting principles by a certified public accounting firm of national standing.

29 (c) The Company shall not be obligated under this Agreement to provide (a) information that is a Trade Secret if the recipient has not demonstrated to the Company’s reasonable satisfaction that it has procedures in place to prevent the dissemination of such Trade Secret so as to result in the potential loss of such Trade Secret being treated as such or (b) privileged information that, by being so disclosed, would cause the information to not be protected by attorney-client privilege; and provided, further, that any information so disclosed shall be treated as Confidential Information of the Company and treated by such Major Investor as provided in this Agreement. 7.02 Inspection Rights. Each Major Investor shall have the right to visit and inspect any of the properties of the Company or any of its subsidiaries, and to discuss the affairs, finances and accounts of the Company or any of its subsidiaries with its officers, and to review such information as is reasonably requested all at such reasonable times and as often as may be reasonably requested by such Major Investor. 7.03 Directors’ Liability, Indemnification and Insurance; Successor Indemnification. The Company shall obtain and maintain, at its expense, D&O insurance at such levels as are customary and reasonable for a company of its size and industry. If the Company or any of its successors or assignees consolidates with or merges into any other entity and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the obligations of the Company with respect to indemnification of members of the Board as in effect immediately before such transaction, whether such obligations are contained in the Company’s Restated Certificate, or elsewhere, as the case may be. 7.04 Approval Matters. (a) The Company hereby covenants and agrees with each of the Investors that it shall not, without approval of the Board in accordance with Delaware General Corporation Law and the Bylaws of the Company, excluding any Director not entitled to vote thereon: (i) repurchase, redeem or otherwise acquire any equity securities (or securities convertible into or exercisable for equity securities); provided that the foregoing shall not restrict repurchases from current or former employees, directors, consultants or other service providers pursuant to equity agreements upon termination of service or pursuant to contractual rights of first refusal, at cost or fair market value; (ii) adopt or amend any equity compensation plan; (iii) approve, adopt, amend, or deviate from any annual budget or operating plan; provided however, if an annual budget or operating plan for a fiscal year is not approved by the start of that year, the most recently approved plan and budget shall apply, adjusted only for (i) non-discretionary increases, (ii) contractual commitments, and (iii) revenue-driven variable costs; (iv) directly or indirectly, enter into, amend, waive, terminate, or consummate any Related Party Transaction; (v) amend, modify, supplement or terminate the License Agreement; (vi) issue any equity securities of the Company (or rights to acquire equity securities or other capital stock of the Company), other than (A) pursuant to the terms of any equity incentive plans or other similar arrangements adopted and approved by the Board, (B) in connection with

Covenants of the Parties. 8.01 Public Announcements. Following the date hereof, no Party shall cause the publication of any subsequent press release, public announcement or disclosure (such subsequent press release, public

31 announcement or disclosure, a “Subsequent Announcement”) regarding this Agreement or the transactions contemplated hereby without the prior written consent of (i) the Company and (ii) any other Parties named in the Subsequent Announcement (which consent or consents shall not be unreasonably withheld, delayed or conditioned), and the Parties shall cooperate as to the timing and contents of any such Subsequent Announcement, except as may be required by applicable Law or any regulations, policies or rules of any regulatory agency or any stock exchange of competent jurisdiction, in which case the Party required to publish or disseminate the Subsequent Announcement shall, to the extent practicable, allow the Company a reasonable opportunity to comment on such Subsequent Announcement in advance of such publication. Notwithstanding the foregoing, in the event that a Subsequent Announcement that is a press release or other similar public announcement does not name one or more of the Parties, any Party causing the publication of such Subsequent Announcement shall, to the extent practicable, provide advance written notice to any such Parties not mentioned in the Subsequent Announcement, which notice shall contain the text of the Subsequent Announcement. 8.02 Compliance with Applicable Law. The business and operations of the Company and all actions of the Stockholders with respect thereto, shall be conducted in compliance in all material respects with all applicable Laws in the United States and other applicable jurisdictions, including but not limited to Laws relating to the prevention of corruption or bribery, including the U.S. Foreign Corrupt Practices Act of 1977, as amended, and the UK Bribery Act 2010, Laws relating to export, reexport, transfer, and import controls, including those administered by the United States (including by the U.S. Department of Commerce, the U.S. Department of State, or U.S. Customs and Border Protection), the European Union, any EU Member State, or any other relevant Government Authority, the Patriot Act, Laws relating to fair labor practices, Laws relating to environmental health and safety, and other requirements of all Governmental Authorities having jurisdiction over the Company and all rules and regulations of Governmental Authorities applicable to the Company. 8.03 Notice of Certain Events.

(b) Each Party shall use reasonable best efforts to give all notices to, and obtain all consents from, all third parties that are necessary for the consummation of the transactions contemplated under the Transaction Agreements.

32 (c) Notwithstanding the foregoing, nothing in this Section 8.04 shall require, or be construed to require, a Party or its Affiliate to agree to (A) sell, hold, divest, discontinue, or limit any assets, businesses, or interests of such Party or any of its Affiliates; (B) any conditions relating to, or changes or restrictions in, the operations of any such assets, businesses, or interests which, in either case, could reasonably be expected to materially and adversely impact the economic or business benefits to such Party or its Affiliates of the transactions contemplated by the Transaction Agreements; or (C) any material modification or waiver of the terms and conditions of the Transaction Agreements. 8.05 Amendment to Restated Certificate. In the event that (i) the Parties approve any of the following in accordance with the approval requirements set forth in this Agreement and the Restated Certificate: (a) an Approved Sale or (b) an Initial Offering; (ii) a Lender delivers a Conversion Notice and does not revoke such Conversion Notice, in each case pursuant to Section 5.01 of the Investment Agreement; or (iii) the Board approves any transaction, or receives any notice, in each case, that would result in the conversion of Stockholder Shares or Options or Convertible Securities to, or exercise of Options or Convertible Securities for, Common Stock under the terms of the Restated Certificate or an agreement evidencing Options or Convertible Securities, then, the Parties shall, prior to any such event, (1) approve an amendment to the Restated Certificate to increase the number of shares of Common Stock authorized for issuance by the Company such that the Company shall have an amount of Common Stock authorized for issuance sufficient to issue the number of shares of Common Stock the Company would be required to issue to LanzaTech in connection with such Approved Sale or Initial Offering, as applicable, or to each Lender in connection with a Conversion Notice, or to a holder of an Option or Convertible Securities, in each case, as required by the Investment Agreement, or otherwise pursuant to an Option or Convertible Securities and (2) otherwise approve the issuance of such shares of Common Stock to LanzaTech, such Lender, or such Holder. All Stockholders agree to vote or cause to be voted, or consent or cause to consent, all Stockholder Shares owned by such Stockholder, or over which such Stockholder has voting control, as may be required to perform the obligations of this Section 8.05. 8.06 Department of Energy Grants. LanzaTech hereby covenants to the Company to use its commercially reasonable efforts (i) to comply with all requirements of the Department of Energy grants issued in 2016 and 2019 to LanzaTech (the “DOE Grants”) and (ii) to use all such grants in compliance with all applicable Laws and for the development and construction of the Demonstration Facility. 8.07 Compliance with DOE Grants. The Company hereby covenants to LanzaTech that it shall cooperate with LanzaTech to the extent required for LanzaTech to comply with LanzaTech’s obligations under the DOE Grants. 9. Other Agreements Among the Stockholders. 9.01 Additional Cash Investments and Other Fundings. No Stockholder or Investor shall have the right or obligation to make any cash or other investment or provide any loan to the Company without the prior written consent of such Stockholder or Investor, including, but not limited to, any subscription for, purchase of, or any other acquisition of any Stockholder Shares or any other shares or securities issued by the Company (or rights to acquire any of the foregoing), any debt security or stockholder loans, or any guarantees for the benefit of the Company or any Stockholder or Investor. 9.02 Non-Solicitation.

33 (a) From the date hereof until the second anniversary of the termination of this Agreement, Stockholders shall not, and shall not cause or permit any of its Affiliates to, directly or indirectly, hire or solicit for employment or for other services, any person who is or was employed by the Company or any Affiliate, or encourage any such employee to leave such employment, except pursuant to a general solicitation which is not directed specifically to any such employees; provided, that nothing in this Section 9.02(a)(i) shall prevent any Stockholder or its Affiliates from hiring (A) any such employee whose employment has been terminated by the Company or any Affiliate or (B) after one year from the date of termination of employment, any employee whose employment has been terminated by the employee. (b) Each Party acknowledges that the restrictions contained in Section 9.02(a) are reasonable and necessary to protect the legitimate interests of the other Parties and constitute a material inducement to the other Parties to enter into this Agreement and consummate the transactions contemplated hereby. In the event that any covenant contained in Section 9.02(a) should ever be adjudicated to exceed the time, geographic, product, service, or other limitations permitted by applicable Law in any jurisdiction, then any court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, or other limitations permitted by applicable Law. The covenants contained in Section 9.02(a) and each provision thereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction. 9.03 Confidentiality and Non-Use Obligations. (a) Each Stockholder recognizes and acknowledges that: (i) it has been or will be provided access under this Agreement and the other Transaction Agreements to certain Confidential Information of LanzaTech, Company and other Stockholders; (ii) all rights in such Confidential Information shall remain the sole and exclusive property of LanzaTech, Company or the applicable Stockholder, as applicable (subject to the rights of LanzaTech and the Company under the License Agreement and the right of the Investors under any Commercial Offtake Agreement, or the Future Development Rights Agreement); and (iii) the Confidential Information is confidential, proprietary information and includes Trade Secrets that are not generally known or easily accessible. (b) Each Party shall, and shall cause its Representatives to, (i) keep confidential and secret and not reveal to any other Person any Confidential Information of any other Party, (ii) protect, preserve and maintain all Trade Secrets of any other Party, and not disclose or authorize the disclosure of any such Trade Secret to any Person other than pursuant to a written confidentiality agreement, and (iii) at all times protect the confidentiality of such Confidential Information, with such measures and by using at least as much diligence as it accords its own proprietary and confidential information, but in no event shall any Party exercise less than reasonable standard of care. Each Party may only disclose such Confidential Information to its Representatives on a “need to know” basis, subject to (x) any such Representatives to which or to whom it wishes to disclose any such Confidential Information having theretofore entered into confidentiality and non-use restrictions at least as restrictive as those set forth herein and (y) such Party informing each such Representative that such Confidential Information is subject to restrictions on disclosure and usage hereunder. (c) Other than as set forth in the License Agreement, any Commercial Offtake Agreement, or the Future Development Rights Agreement, each Party agrees that it shall not, and shall not permit its Representatives to, use any Confidential Information of another Party for any reason or purpose other than in connection with the Business (on behalf of or through (directly or indirectly) the Company or

34 LanzaTech, as applicable) or as contemplated by any of the Transaction Agreements or performing obligations or exercising or enforcing rights hereunder or thereunder. (d) With respect to Confidential Information that any Party identifies in writing as constituting highly sensitive Trade Secrets of such Party (“Highly Sensitive Trade Secrets”), each Party will take all additional precautions which may be reasonably necessary to preserve such trade secret rights, including the following: (a) each Party will store all copies of the Highly Sensitive Trade Secrets in a locked room or vault or, for electronic copies, encrypted on a secure server, in each case to which only the Parties’ employees that are individually named and approved in writing by the owner of the Highly Sensitive Trade Secrets (“Named Employees”) have access (such approval not to be unreasonably withheld); (b) each Party will ensure that each Named Employee signs a written confidentiality agreement, enforceable by the owner of the Highly Sensitive Trade Secrets as an intended third party beneficiary, specifically describing the Named Employee’s obligations to secure and protect the confidentiality of, and not use for any purpose not authorized hereunder, the Highly Sensitive Trade Secrets; (c) each Party will keep complete and accurate records of each Person who accesses the Highly Sensitive Trade Secrets and for what purpose, and provide such records to the owner of the Highly Sensitive Trade Secrets upon request;. Breach of this Section 9.03 will be automatically deemed to be a material breach of this Agreement and will entitle the owner of the Highly Sensitive Trade Secrets to Injunctive Relief under Section 11.04(c). (e) The confidentiality obligations set forth in this Section 9.03 shall not limit any Party or its Representatives’ right to disclose Confidential Information that such Party is required to disclose under any applicable Laws or pursuant to the regulations, policies or rules of any regulatory agency or any stock exchange of competent jurisdiction (provided that in the event disclosure is required pursuant to this clause by applicable Laws or the regulations, policies or rules of any regulatory agency or any stock exchange, such Person shall, to the extent reasonably possible, (A) provide the Parties from whom or from whose Affiliates such information is obtained with prompt notice of such requirement prior to making any disclosure so that such other Parties or any of their Affiliates may seek an appropriate protective order and (B) provide the minimum disclosure of such Confidential Information as is practicable under the circumstances and use commercially reasonable efforts to obtain confidential treatment of such disclosed information). (f) If a Party becomes aware of an unauthorized use or disclosure of another Party’s Confidential Information in its possession or control, such Party shall promptly notify the owner of the Confidential Information, which may take, at the notifying Party’s expense, all steps which are necessary to recover the Confidential Information disclosed or used in breach of this Agreement and to prevent its subsequent unauthorized use or dissemination, including availing itself of Actions for seizure and Injunctive Relief. (g) The obligations set forth in this Section 9.03 shall be continuing and survive the termination of this Agreement for (i) a period of five years as to the Company, and as to any Stockholder until the fifth (5th) anniversary of such date as such Stockholder ceases to be a stockholder of the Company, or (ii) for Confidential Information that is a Trade Secret, indefinitely (until such Confidential Information no longer meets the definition of Trade Secret under this Agreement). (h) For the avoidance of doubt, this Section 9.03 does not supersede any agreements implementing the Company’s protection protocols with respect to sensitive information in effect between the parties.

35 10. Termination or Dissolution of the Company. 10.01 Termination. This Agreement shall continue in full force and effect from the date hereof through the earliest of the following dates, on which date it shall terminate in its entirety except as provided in Section 10.02: (a) the date of the closing of an Initial Offering or a Deemed Liquidation Event (as defined in the Restated Certificate); or (b) the date as of which the Parties hereto terminate this Agreement by written consent of all of the Parties, in accordance with Section 11.08 herein. 10.02 Effect of Termination. In the event of the termination of this Agreement in accordance with Section 10.01, this Agreement shall forthwith become void and there shall be no liability on the part of any Party hereto except: (a) In the event of a termination upon an Initial Offering, the following Sections and the rights and obligations therein shall survive any such termination of the Agreement, (i) as set forth in Sections 6, 7 and 9, and (ii) Section 10 and Section 11; (b) In the event of a termination upon an Approved Sale or Deemed Liquidation Event, Section 7.03, Section 9.03, Section 10 and Section 11 and the rights and obligations therein, shall survive any such termination of the Agreement; and (c) that nothing herein shall relieve any Party from liability for any liability resulting from any breach of this Agreement prior to such termination. 10.03 Buy-Sell. (a) Notwithstanding anything to the contrary herein, at any time prior to an Initial Offering, each Investor (each, a “Put Option Holder”) shall have a right and option (a “Put Option”) to require the Company to purchase all, but not less than all, of the Common Stock held by such Investor, as applicable (the “Put Option Stock”), at a price per share of $0.0001 (the “Put Option Exercise Price”), upon the occurrence of any of the below: (i) any determination by the Battelle Memorial Institute that is not challenged by the Company, or any final, non-appealable determination by a third-party adjudicator, in each case, of the invalidity of the Licensed IPR or LanzaTech Technology or any material portion thereof; (ii) any termination of the License Agreement or the Battelle Agreement that is not replaced or restated with materially equivalent rights in favor of the Company; (iii) the relevant Investor determining that the Company has engaged in conduct that is either (1) unlawful or (2) in breach of the E&C Policy; or (iv) to the extent that a Regulated Holder (as defined in the Restated Certificate) would be entitled to greater than 33.33% of the Company’s “Total Equity” (as defined in, and calculated pursuant to, § 225.34 of Regulation Y) upon the acquisition of control over equity instruments of the Company (including, but not limited to, the preferred stock and common stock) by such Regulated Holder, notwithstanding anything to the contrary, in lieu of such amount of the Company’s Total Equity in

36 excess of 33.3%, the Regulated Holder shall have the Put Option, to the extent legally permissible, with respect to such amount in excess of 33.33% of the Company’s Total Equity. As used in this provision, an “acquisition of control over equity instruments” means any transaction, conversion or other acquisition event that would fall within the scope of § 225.34(e) of Regulation Y. (b) The Put Option shall be exercisable by a Put Option Holder only by delivery of a written notice to the Company in accordance with Section 11.08 certifying such Put Option Holder’s election to exercise its Put Option and setting forth the number of shares of Put Option Stock held by such Put Option Holder being sold pursuant to such exercise, together with the certificate or certificates representing all of the shares of Put Option Stock held by such Put Option Holder at the time of the exercise of the Put Option (such notice, the “Put Option Notice”). (c) Subject to compliance with Section 10.03(a)-(b), the Company shall pay to each Put Option Holder who has exercised its Put Option the Put Option Exercise Price upon the receipt of a properly executed Put Option Notice. Such payment may be effected in cash or by certified bank check or wire transfer. The Put Option shall be deemed to have been exercised immediately prior to the close of business on the date of receipt of the Put Option Notice. Failure to deliver a Put Option Notice prior to the expiration of the Put Option shall constitute an irrevocable waiver of the Put Option. (d) Notwithstanding any other provision of this Section 10.03, if the Company is unable or not permitted under applicable Law, to pay all or part of the Put Option Exercise Price pursuant to the exercise of the Put Option, the Company shall pay the Put Option Exercise Price and purchase the shares of Put Option Stock subject to the Put Option as soon as the Company is able and the applicable Laws permit the Company to do so. Shares of Put Option Stock for which the Put Option Exercise Price have not been paid in full shall remain issued and outstanding. To the extent a Put Option Holder has exercised the Put Option pursuant to this Section 10.03 but did not receive its Put Option Exercise Price pursuant to this Section 10.03(d), until receipt of the Put Option Exercise Price, such Put Option Holder shall continue to have all rights available to it as an Investor prior to its exercise of the Put Option. 10.04 Winding Up and Liquidation. (a) Upon the dissolution of the Company, its affairs shall be wound up as soon as practicable thereafter by the Stockholders. Except as otherwise provided in subsection (c) of this section, in winding up the Company and liquidating the assets thereof, the Board, or other persons so designated for such purpose, may arrange for the collection and disbursement to each Stockholder of any future receipts from the Company property or other sums to which the Stockholder may be entitled, or may sell the Company’s interest in the Company property to any person, including persons related to a Stockholder, on such terms and for such consideration as shall be consistent with obtaining the fair market value thereof. (b) Upon the dissolution of the Company, the assets, if any, of the Company available for distribution and any net proceeds from the liquidation of any such assets, shall be applied and distributed in the following manner or order, to the extent available: (i) To the payment of or provision for all debts, liabilities, and obligations of the Company to any person, and the expenses of liquidation; and (ii) to the Stockholders in accordance with the Restated Certificate. (c) Upon dissolution, a reasonable time shall be allowed for the orderly liquidation of the assets of the Company and the discharge of liabilities to creditors so as to minimize the losses normally attendant to a liquidation.

(c) Each Party acknowledges and agrees that a breach of this Agreement may give rise to irreparable harm for which monetary damages would not be an adequate remedy. Each Party accordingly agrees that, notwithstanding the provisions of this Section and subject to Section 11.06, each Party shall be entitled to seek to enforce the terms of this Agreement by decree of specific performance or to obtain injunctive relief against any breach or threatened breach of this Agreement in any court of competent jurisdiction (collectively, “Injunctive Relief”).

40 (a) Issuance. Subject to Article 5 and after receipt of the required approvals as set forth in the Restated Certificate, in the event that after the date of this Agreement, the Company enters into an agreement with any person to issue shares of capital stock to such person or issues shares of capital stock to such person (other than options to purchase Class B Common Stock, which shall be subject to the terms and conditions, including restrictions on transfer, set forth in the Equity Incentive Plan), then, the Company shall cause such person, as a condition precedent to the issuance of such shares of capital stock of the Company, to become party to this Agreement by executing a Joinder Agreement, agreeing to be bound by and subject to the terms of this Agreement as a Stockholder and thereafter such person shall be deemed a Stockholder for all purposes under this Agreement. For the avoidance of doubt, the holders of any Class B Common Stock shall be required to execute a Joinder Agreement upon any conversion of the Class B Common Stock into shares of Common Stock. (b) Transfer. Each transferee or assignee of any Stockholder Shares subject to this Agreement shall continue to be subject to the terms hereof, and, as a condition precedent to the Company’s recognition of such Transfer, each transferee or assignee shall agree in writing to be subject to each of the terms of this Agreement by executing and delivering a Joinder Agreement.

This Agreement shall be binding upon and shall inure to the benefit of the Parties and their permitted successors assigns. This Agreement and the rights and obligations hereunder may not be assigned or otherwise transferred (including by merger, consolidation, change of control, or operation of law) by a Party without the written consent of the other Parties; other than to a Permitted Transferee or as otherwise provided in accordance with Section 3. The Company shall not assign this Agreement or any of its rights, benefits or obligations or any portion thereof arising hereunder or relating hereto without the prior written consent of the other Parties. Any such purported assignment without the prior written consent of the Parties shall be null and void. No assignment of any rights or obligations hereunder shall relieve the assigning Party of any such obligations. Upon any assignment permitted under this Agreement, the references in this Agreement to such assigning Party shall also apply to any such assignee unless the context otherwise requires. 11.14 No Third-Party Beneficiaries. This Agreement is for the sole benefit of the Parties and their respective successors and permitted assigns and nothing herein, express, or implied, is intended to or shall confer upon any other person any legal or equitable right, benefit, or remedy of any nature whatsoever. 11.15 Amendment or Waiver. This Agreement may be amended, modified or terminated and the observance of any term hereof may be waived (either generally or in a particular instance and either retroactively or prospectively) only by a written instrument executed by (a) the Company; and (b) each of the Stockholders. 11.16 Relationship of Parties. The relationship of the Parties established by this Agreement is that of independent contractors, and nothing herein shall be construed to constitute the Parties as partners, joint venturers, co-owners, or otherwise as participants in a joint or common undertaking, except as specifically set forth in this Agreement. No Party has any authority to either obligate any other or any of its Affiliates in any respect or hold itself out as having any such authority unless specifically agreed upon by the Parties in advance and in writing.

41 11.17 Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together shall be deemed to be one and the same agreement.

In the event that subsequent to the date of this Agreement any stock or other securities are issued on, or in exchange for, any of the Stockholder Shares by reason of any stock dividend, stock split, combination of shares, reclassification or the like, such shares or securities shall be deemed to be Stockholder Shares for purposes of this Agreement. All references to a number of shares of a series or class of capital stock shall be automatically adjusted to reflect any stock splits, stock combinations, stock dividends, recapitalizations, reorganizations or the like occurring after the date hereof with respect to such series or class, as applicable. 11.19 Conflict. In the event of any conflict between the terms of this Agreement and the Restated Certificate or the Company’s Bylaws, the Parties hereto shall, to the extent permitted by law, promptly approve an amendment to the Restated Certificate of the Company’s Bylaws to conform it to the terms of this Agreement. 11.20 Aggregation of Stock.
