HumanCo Acquisition Corp. P.O. Box 90608 Austin, TX 78709 Re: Initial Public Offering Ladies and Gentlemen:

1.

The Sponsor, HumanCo SPV, CAVU and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within 24 months from the closing of the Public Offering, or such later period approved by the Company’s stockholders in accordance with the Company’s amended and restated certificate of incorporation (the “Charter”), the Sponsor, HumanCo SPV, CAVU and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than 10 Business Days thereafter, subject to lawfully available funds therefor, redeem 100% of the Common Stock sold as part of the Units in the Public Offering (the “Offering Shares”) and the Common Stock sold as part of the CAVU Units (the “CAVU Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account (as defined below), including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares and CAVU Shares, which redemption will completely extinguish all Public Stockholders’ and holders of CAVU Shares’ rights as stockholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor, HumanCo SPV, CAVU and each Insider agrees not to propose any amendment to the Charter to (a) modify the substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or the Company’s obligation to redeem 100% of the Offering Shares and CAVU Shares if the Company does not complete a Business Combination within the time period set forth in the Charter or (b) with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides Public Stockholders with the opportunity to redeem their shares of Common Stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account (excluding any amounts then on deposit in the Trust Account that are allocable to the CAVU Shares), including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable and excluding any interest earned on the funds held in the Trust Account that are allocable to the CAVU Shares) and not previously released to the Company to pay its franchise and income taxes, divided by the number of then outstanding Offering Shares.

2.

The undersigned acknowledges and agrees that prior to entering into a definitive agreement for a Business Combination or subsequent transaction with a target business that is affiliated with the undersigned or any other Insiders of the Company or their affiliates, such transaction must be approved by a majority of the Company’s disinterested independent directors and the Company, or a committee of independent directors, must, to the extent required by applicable law or based upon the direction of the Company’s board of directors or a committee thereof, obtain an opinion from an independent investment banking firm or another entity that commonly renders valuation opinions that such Business Combination or transaction is fair to the Company from a financial point of view.

3.

During the period commencing on the date of the Underwriting Agreement and ending 180 days after such date, the Sponsor, HumanCo SPV, CAVU and each Insider shall not, without the prior written consent of the Underwriter, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, any Units, CAVU Units, shares of Common Stock, Founder Shares, Warrants, Private Placement Warrants, CAVU Warrants or any securities convertible into, or exercisable or exchangeable for, shares of Common Stock owned by it, him or her, (ii) establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, with respect to any Units, CAVU Units, shares of Common Stock, Founder Shares, Warrants, Private Placement Warrants, CAVU Warrants or any securities convertible into, or exercisable or exchangeable for, shares of Common Stock (but excluding Units and shares of Common Stock purchased in the Public Offering or thereafter) owned by it, him or her, (iii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Units, CAVU Units, shares of Common Stock, Founder Shares, Warrants, Private Placement Warrants, CAVU Warrants or any securities convertible into, or exercisable or exchangeable for, shares of Common Stock owned by it, him or her, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iv) publicly announce any intention to effect any transaction specified in clause (i) , (ii) or (iii). The provisions of this paragraph will not apply if the release or waiver is effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

4.

In the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business Combination within the time period set forth in the Charter, the Sponsor (the “Indemnitor”), which for purposes of clarification shall not extend to any shareholders, members or managers of the Sponsor, or any of the other undersigned, agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company or (ii) any prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or Business Combination agreement (a “Target”); provided, however, that such indemnification of the Company by the Indemnitor (x) shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Offering Share and CAVU Share and (ii) the actual amount per Offering Share and CAVU Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Offering Share and CAVU Share is then held in the Trust Account due to reductions in the value of the trust assets, less interest earned on the funds in the Trust Account which may be withdrawn to pay franchise and income taxes, (y) shall not apply to any claims by a third party or a Target which executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) and (z) shall not apply to any claims under the Company’s indemnity of the Underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Indemnitor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

5.

To the extent that the Underwriter does not exercise its over-allotment option to purchase up to an additional 3,375,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus) in full, the Sponsor agrees to forfeit, at no cost, a number of Founder Shares in the aggregate equal to 843,750 multiplied by a fraction (i) the numerator of which is 3,375,000 minus the number of Units purchased by the Underwriter upon the exercise of its over-allotment option, and (ii) the denominator of which is 3,375,000.  For clarity, the forfeiture shall yield the result that the Initial Stockholders will own an aggregate of 20% of the Company’s issued and outstanding shares of Capital Stock after the Public Offering (excluding the CAVU shares and assuming that the Initial Stockholders do not purchase any Units in the Public Offering).

6.

The Sponsor, HumanCo SPV, CAVU and each Insider hereby agrees and acknowledges that: (i) the Underwriter and the Company would be irreparably injured in the event of a breach by such Sponsor, HumanCo SPV, CAVU or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 6, 7(a), 7(b) and, solely as to each D&O Insider, 8, as applicable, of this Letter Agreement, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

7.

(a)          The Sponsor, HumanCo SPV, CAVU and each Insider agrees that it, he or she shall not Transfer any Founder Shares or CAVU Shares (or shares of Common Stock issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial Business Combination or (B) subsequent to the Company’s initial Business Combination, (x) if the last reported sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property (the “Founder Shares Lock-up Period”).

(b)          The Sponsor, HumanCo SPV, CAVU and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants or CAVU Warrants (or shares of Common Stock issued or issuable upon the exercise thereof) until 30 days after the completion of the Company’s initial Business Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).

(c)          Notwithstanding the provisions set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, CAVU Shares, Private Placement Warrants, CAVU Warrants and shares of Common Stock issued or issuable upon the exercise or conversion thereof and, with respect to the Founder Shares, Private Placement Warrants and shares of Common Stock issued or issuable upon the exercise or conversion thereof, that are held by the Sponsor, HumanCo SPV, CAVU, any Insider or any of their permitted transferees (that have complied with this paragraph 7(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, the Sponsor, any members of the Sponsor, any affiliates of the Sponsor or CAVU, or any affiliates of such members and funds and accounts advised by such members or any limited partners of any such funds that are invested in the Sponsor or the limited partners of CAVU; (b) in the case of an individual, by gift to a member of such individual’s immediate family or to a trust, the beneficiary of which is a member of such individual’s immediate family, an affiliate of such individual or to a charitable organization; (c) in the case of an individual, by virtue of the laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with the consummation of an initial Business Combination at prices no greater than the price at which the Founder Shares, CAVU Shares, Private Placement Warrants, CAVU Warrants or shares of Common Stock were originally purchased; (f) to an entity that is an affiliate of the holder; (g) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (h) by virtue of the laws of the State of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; (i) in the event of the Company’s liquidation, merger, capital stock exchange, reorganization or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property subsequent to the completion of an initial Business Combination; or (j) to the Company for no value for cancellation in connection with the consummation of the initial Business Combination; provided, however, that, in the case of clauses (a) through (f) or (h), these permitted transferees must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in this paragraph 7(c) and the other restrictions contained in this Letter Agreement.

8.
