Re: Initial Public Offering

Ladies and Gentlemen:

This letter (“Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into, or proposed to be entered into, by and among INSU Acquisition Corp. III, a Delaware corporation (the “Company”), and Cantor Fitzgerald & Co. and Wells Fargo Securities, LLC, as the representatives of the underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Offering”), of up to 25,070,000 of the Company’s units (the “Units”), each comprised of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Common Stock”), and one third of one warrant, each whole warrant exercisable for one share of Common Stock (each, a “Warrant”). The Units sold in the Offering will be registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”). The Company expects that the Units will be listed for trading on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph 16 hereof.

The Insiders signatory hereto hereby agree with the Company as follows:

1. Each Insider agrees that, if the Company seeks stockholder approval of (a) a proposed initial Business Combination or (b) a proposed amendment to the Company’s amended and restated certificate of incorporation (as may be amended from time to time, the “Charter”) to modify the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete its initial Business Combination within 24 months from the completion of the Offering, then in connection with such proposed initial Business Combination or amendment to the Charter, such person shall vote, as applicable, all Founder Shares, Placement Shares and any shares acquired by such person in the Offering or in the secondary public market in favor of such proposed initial Business Combination or such amendment to the Charter, as applicable.

2. (a) Each Insider hereby agrees that, if the Company fails to consummate a Business Combination within 24 months from the consummation of the Offering, such person 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 ten business days thereafter, redeem the Offering Shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including any amounts representing interest earned on the Trust Account, less interest previously released to, or reserved for use by, the Company in an amount up to $100,000 to pay dissolution expenses and less any other interest released to, or reserved for use by, the Company to pay franchise and income taxes, divided by the number of Offering Shares then outstanding, which redemption will completely extinguish the holder’s rights as a stockholder with respect to his, her or its Offering Shares (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 (the “Board”), dissolve and liquidate, subject in the case of clauses (ii) and (iii) to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law.

(b) Each Insider agrees to not propose any amendment to the Charter that would affect the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not consummate a Business Combination within 24 months from the completion of the Offering, unless the Company provides the holders of Offering Shares with the opportunity to redeem their Offering Shares 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, including any amounts representing interest earned on the Trust Account, less any interest released to, or reserved for use by, the Company to pay franchise and income taxes, divided by the number of then outstanding Offering Shares.

(c) Each Insider acknowledges and agrees that Founder Shares or Placement Shares held by him, her or it are not entitled to, and have no right, interest or claim of any kind in or to, any monies held in the Trust Account or distributed as a result of any liquidation of the Trust Account.

(d) Each Insider waives, with respect to any Founder Shares or Placement Shares held by such undersigned party, any redemption rights he, she or it may have (i) in connection with the consummation of an initial Business Combination, (ii) if the Company fails to consummate its initial Business Combination or liquidates within 24 months from the completion of the Offering or (iii) if the Company seeks an amendment to its Charter that would affect the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares as described above. If any of the Insiders should acquire Offering Shares in or after the Offering, each Insider hereby waives with respect to such Offering Shares held by such undersigned party any redemption rights such party may have in connection with the consummation of a Business Combination or a stockholder vote to amend the Charter to modify the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete its initial Business Combination within 24 months from the completion of the Offering; provided, however, that the Insiders will be entitled to redemption rights with respect to such Offering Shares held by them if the Company fails to consummate a Business Combination or liquidates within 24 months from completion of the Offering.

3. (a) To the extent that the Underwriters do not exercise in full their over-allotment option to purchase an additional 3,270,000 Units (as described in the Prospectus), the Initial Holders shall return to the Company for cancellation, at no cost, an aggregate number of Founder Shares determined by multiplying 1,090,000 by a fraction: (i) the numerator of which is 3,270,000 minus the number of shares of the Common Stock purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 3,270,000. The Initial Holders further agree that, if the Company effects a stock split, stock dividend, reverse stock split, contribution back to capital or otherwise in connection with any increase or decrease in the size of the Offering, to the extent that the Underwriters do not exercise their over-allotment option in full, the aggregate number of shares that the Initial Holders will be required to return to the Company as set forth in the immediately preceding sentence shall be adjusted so that the Founder Shares held by the Initial Holders and their Permitted Transferees represent 25% of the Company’s issued and outstanding shares of Common Stock immediately following such forfeiture. The number of Founder Shares to be returned by each Initial Holder, if any, pursuant to this Section 3(a) shall be determined on a pro-rata basis based on the percentage of outstanding Founder Shares held by each Initial Holder at the time of such forfeiture.

(b) Subject to paragraph 3(d), the Founder Shares owned by the Insiders shall not be transferable or salable (x)(a) with respect to 25% of such shares, until consummation of a Business Combination, (b) with respect to 25% of such shares, when the closing price of the Common Stock exceeds $12.00 for any 20 trading days within a 30-trading day period following the consummation of a Business Combination, (c) with respect to 25% of such shares, when the closing price of the Common Stock exceeds $13.50 for any 20 trading days within a 30-trading day period following the consummation of a Business Combination, and (d) with respect to 25% of such shares, when the closing price of the Common Stock exceeds $17.00 for any 20 trading days within a 30-trading day period following the consummation of a Business Combination or earlier, in any case, if, following a Business Combination (y) the Company completes a liquidation, merger, stock exchange 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 (such applicable period being the “Founder Lock-Up Period”). During the Founder Lock-Up Period, the Insiders shall not, except as described in the Prospectus, (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, or 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, and the rules and regulations of the Commission promulgated thereunder (the “Exchange Act”), with respect to the Founder Shares then subject to the Founder Lock-Up Period, (II) 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 of the Founder Shares then subject to the Founder Lock-Up Period, whether any such transaction is to be settled by delivery of the Common Stock or such other securities, in cash or otherwise, or (III) publicly announce any intention to effect any transaction specified in clause (b)(I) or (b)(II).

(c) Until 30 days after the consummation of the initial Business Combination (“Placement Unit Lock-Up Period”), the Sponsor shall not, except as described in the Prospectus, (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, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to the Placement Units, Placement Shares, Placement Warrants, or shares of Common Stock underlying the Placement Warrants, (ii) 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 of the Placement Units, Placement Shares, Placement Warrants, or shares of Common Stock underlying the Placement Warrants, whether any such transaction is to be settled by delivery of the Common Stock or such other securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (c)(i) or (c)(ii).

(d) Notwithstanding the provisions contained in paragraphs 3(b) and 3(c) hereof, any Insider may transfer, as applicable, the Founder Shares and/or Placement Units, Placement Shares, Placement Warrants, or shares of Common Stock underlying the Placement Warrants (1) in connection with an initial Business Combination with the consent of the Company to any third party that agrees in writing to be bound by the provisions of this agreement applicable to Insiders (other than paragraph 1 and the second sentence of paragraph 2(d)); and (2) (a) to the Company’s officers, the Company’s directors, the Initial Holders, or other Insiders, (b) to an affiliate or immediate family member of any of the Company’s officers and directors, Initial Holders, or other Insiders, (c) to any member, officer or director of the Sponsor, or any immediate family member, partner, affiliate or employee of a member of the Sponsor, (d) by gift to any Permitted Transferee under any of the immediately preceding subsections (a) through (c), a trust, the beneficiaries of which are one or more Permitted Transferees under any of the immediately preceding subsections (a) through (c), or a charitable organization, (e) by virtue of laws of descent and distribution upon death of any of the Company’s officers, the Company’s directors, the Initial Holders, or members of the Sponsor, (f) pursuant to a qualified domestic relations order, (g) in the event of the Company’s liquidation prior to consummation of its initial Business Combination, (h) by virtue of the laws of Delaware, the Sponsor’s limited liability company agreement upon dissolution of the Sponsor, (i) subsequent to the Company’s consummation of its initial Business Combination, in the event of a liquidation, merger, stock exchange 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, (j) subsequent to the Company’s consummation of its initial Business Combination, in the event of a consolidation, merger or other similar transaction in which the Company is the surviving entity that results in the directors and officers of the Company ceasing to comprise a majority of the Board (in the case of directors) or management (in the case of officers) of the surviving entity or (k) through private sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the consummation of the Company’s initial Business Combination at prices no greater than the price at which the Founder Shares, Placement Shares or Placement Warrants were originally purchased (each, a “Permitted Transferee”); provided, however, that, in the case of subclauses (a) through (f), (h) and (k), these transferees enter into a written agreement with the Company agreeing to be bound by the transfer restrictions set forth herein. For the avoidance of doubt, for the purposes of this Agreement, a managed account managed by the same investment manager of any member of the Sponsor shall be deemed an affiliate of such member.

(e) Further, each Insider agrees that after the Founder Lock-Up Period or the Placement Unit Lock-Up Period, as applicable, has elapsed, the Founder Shares and/or Placement Units, Placement Shares, Placement Warrants, or shares of Common Stock underlying the Placement Warrants owned by such Insider shall only be transferable or saleable pursuant to a sale registered under the Securities Act or pursuant to an available exemption from registration under the Securities Act. The Company and each Insider acknowledges that pursuant to that certain registration rights agreement to be entered into among the Company and certain security holders of the Company, parties to the agreement may request that a registration statement relating to the Founder Shares and/or Placement Units, Placement Shares, Placement Warrants, or shares of Common Stock underlying the Placement Warrants be filed by the Company with the Commission prior to the end of the Founder Lock-Up Period or the Placement Unit Lock-Up Period, as the case may be; provided, however, that such registration statement does not become effective prior to the end of the Founder Lock-Up Period or the Placement Unit Lock-Up Period, as applicable.

(f) Subject to the limitations described herein, each Insider shall retain all of such Insider’s rights as a security holder during, as applicable, the Founder Lock-Up Period and/or Placement Unit Lock-Up Period including, without limitation, the right to vote, as the case may be, the Founder Shares and/or Placement Shares.

(g) During the Founder Lock-Up Period and Placement Unit Lock-Up Period, all dividends payable in cash with respect to such securities shall be paid, as applicable, to each security holder, but all dividends payable in Common Stock or other non-cash property shall become subject to the applicable lock-up period as described herein and shall only be released from such lock-up in accordance with the provisions of this paragraph 3.

4. Without limiting the provisions of paragraph 3(d) hereof, during the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, each of the undersigned shall not (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, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act with respect to any Units, Placement Units, shares of Common Stock, Warrants, Placement Shares, Placement Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by an undersigned party, (ii) 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, Placement Units, shares of Common Stock, Warrants, Placement Shares, Placement Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by the undersigned, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii); provided, however, that the restrictions of this Section 4 shall not apply to any distributions by the Sponsor to its members of Units, Placement Units, shares of Common Stock, Warrants, Placement Shares, Placement Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock.

5. (a) In the event of the liquidation of the Trust Account without the consummation of a Business Combination, the Sponsor (the “Indemnitor”) 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, or any claim whatsoever) 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 (a “Target”) as described in the Prospectus; provided, however, that such indemnification of the Company by the Indemnitor shall apply only to the extent necessary to ensure that such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below $10.00 (regardless of whether or not the Underwriters exercise any portion of their overallotment option) per Offering Share and only if such third party or Target has not executed an agreement waiving claims against any and all rights to seek access to the Trust Account, regardless of whether such agreement is enforceable. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Indemnitor shall not be responsible for any liability as a result of any such third party claims. Notwithstanding any of the foregoing, indemnification of the Company by the Indemnitor pursuant to this paragraph 5 shall not apply as to any claims arising from the Company’s obligation pursuant to the Underwriting Agreement to indemnify the Underwriters.

(b) If the Company is liquidated within 24 months following completion of the Offering, to the extent that interest income on the balance of the Trust Account (net of any taxes payable) released to the Company in an amount up to $100,000 to pay dissolution expenses and any other interest released to, or reserved for use by, the Company to pay franchise and income taxes and loans from the Sponsor (each as described in the Prospectus) are insufficient to fund the costs and expenses of liquidation, the Indemnitor agrees to pay the balance of the amount necessary to complete the liquidation of the Company. 

6. The Company agrees that the Company will not engage any third party to render services, agree to purchase any products from such third party, or enter into any discussion or any acquisition agreement with a Target unless (i) such third party or Target has agreed to execute a waiver against any right, title, interest or claim of any kind in or to any monies held in the Trust Account or any proceeds from the Trust Account, that is acceptable to the Board or (ii) the Board and Sponsor have each consented in writing to dispense with such waiver with respect to such services, product, discussions or acquisition agreement, in each case with the written consent of the Indemnitor as part of the consent of the Board. In addition the Company shall endeavor, together with the officers and directors of any acquisition target for its initial Business Combination, to obtain waivers of claims to the monies held in the Trust Account from creditors of such acquisition target (which, for the avoidance of doubt, shall include creditors existing prior to the initial Business Combination as well as after completion of the initial Business Combination).

7. In order to minimize potential conflicts of interest that may arise from multiple corporate affiliations, each officer and director of the Company who is signatory to this Agreement agrees that until the earliest of the Company’s initial Business Combination, liquidation or the time at which such person ceases to be an officer or director of the Company, such person shall present to the Company for its consideration, prior to presentation to any other entity, any suitable Business Combination opportunities of which such person (or companies or entities which such person manages or controls) becomes aware, subject to any current or future fiduciary or contractual obligations of such person that such person discloses to the Company.

8. Each officer and director signatory hereto represents and warrants that the biographical information furnished to the Company by him or her is true and accurate in all material respects and does not omit any material information with respect to such person’s background. Each of the answers of such person to the items in questionnaires furnished to the Company by such officer and director is true and accurate in all material respects.

9. Each of the undersigned represents and warrants that her, she or it:

(a) is not subject to or a respondent in any legal action for any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction;

(b) has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities, and the undersigned is not currently a defendant in any such criminal proceeding; and

(c) has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked.

10. Each Insider agrees that he, she or it shall receive no finder’s fees, consulting fees or other similar compensation from the Company prior to, or for any services they render in order to effectuate, the consummation of the initial Business Combination, other than the following:

(a) repayment of loans made to the Company by the Sponsor or its affiliate prior to completion of the Offering in connection with organizational expenses and the preparation, filing and consummation of the Offering;

(b) payments to the Sponsor or its affiliate of a total of $20,000 per month for office space, administrative and shared personnel support services, pursuant to an Administrative Services Agreement;

(c) repayment of loans, if any, and on such terms as to be determined by the Company from time to time, made by the Sponsor or one of its affiliates to finance transaction costs in connection with an intended initial Business Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used by the Company to repay such loaned amounts. Up to $1,500,000 of such loans may be convertible into units at a price of $10.00 per unit at the option of the lender. Such units would be identical to the Placement Units;

(d) at the closing of an initial Business Combination, a customary advisory fee to an affiliate of the Sponsor, in an amount that constitutes a market standard advisory fee for comparable transactions and services provided; and

(e) reimbursement for any out-of-pocket expenses related to identifying, investigating and consummating an initial Business Combination, provided that no proceeds of the Offering placed in the Trust Account may be applied to the payment of such expenses prior to the consummation of an initial Business Combination.

Each of the undersigned agrees that neither the Underwriters nor their agents shall be violating such undersigned party’s right of privacy by requesting and obtaining the Information in accordance with this Section 12.

13. Each of the undersigned acknowledges and agrees that the Company will not consummate any initial Business Combination that involves a company which is affiliated with such undersigned party unless the Company obtains an opinion from an independent investment banking firm that is a member of the Financial Industry Regulatory Authority that the Business Combination is fair to the Company’s stockholders from a financial perspective.

14. Each officer and director signatory hereto represents and warrants that he or she has full right and power, without violating any agreement to which such person is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and to serve as an officer of the Company or as a director on the Board, as applicable, and hereby consents to being named in the Prospectus as an officer and/or as a director of the Company, as applicable.

Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, at any time and from time to time on or after the date the Company consummates the Business Combination, the Holders of a majority-in-interest of the then outstanding number of Registrable Securities held by the Sponsor, officers or directors of the Company or their affiliates, or the transferees of the foregoing (the “Demanding Holders”), may make a written demand for Registration under the Securities Act of all or part of their Registrable Securities, which written demand shall describe the amount and type of securities to be included in such Registration and the intended method(s) of distribution thereof (such written demand a “Demand Registration”). The Company shall, within ten (10) days of the Company’s receipt of the Demand Registration, notify, in writing, all other Holders of Registrable Securities of such demand, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in a Registration pursuant to a Demand Registration (each such Holder that includes all or a portion of such Holder’s Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company, in writing, within five (5) Business Days after the receipt by the Holder of the notice from the Company. Upon receipt by the Company of any such written notification from a Requesting Holder(s) to the Company, such Requesting Holder(s) shall be entitled to have their Registrable Securities included in a Registration pursuant to a Demand Registration and the Company shall, not more than forty five (45) days after the Company’s receipt of the Demand Registration, file a Registration Statement on Form S-1 or any similar long-form registration statement that may be available at that time (“Form S-1”) with respect to all Registrable Securities requested by the Demanding Holders and Requesting Holders pursuant to such the Demand Registration, and shall use its reasonable best efforts to cause such Registration Statement to be declared effective by the Commission as soon as practicable thereafter; provided, however, that the Company may use a Registration Statement on Form S-3 or any successor form thereto if the Company would qualify to use such form within 30 days after the date on which the initial demand request is given and the Company shall not be required to file such Registration Statement until it is so qualified. Under no circumstances shall the Company be obligated to effect more than an aggregate of three (3) Registrations pursuant to a Demand Registration under this subsection 2.1.1 with respect to any or all Registrable Securities; provided, however, that a Registration shall not be counted for such purposes unless a Registration Statement has become effective and all of the Registrable Securities requested by the Requesting Holders to be registered on behalf of the Requesting Holders in such Demand Registration have been sold in accordance with Section 3.1 of this Agreement.

2.1.2 Effective Registration. Notwithstanding the provisions of subsection 2.1.1 above or any other part of this Agreement, a Registration pursuant to a Demand Registration shall not count as a Registration unless and until (i) the Registration Statement filed with the Commission with respect to a Registration pursuant to a Demand Registration has been declared effective by the Commission and (ii) the Company has complied with all of its obligations under this Agreement with respect thereto; provided, however, that if after such Registration Statement has been declared effective, an offering of Registrable Securities in a Registration pursuant to a Demand Registration is subsequently interfered with by any stop order or injunction of the Commission, federal or state court or any other governmental agency the Registration Statement with respect to such Registration shall be deemed not to have been declared effective, unless and until, (x) such stop order or injunction is removed, rescinded or otherwise terminated, and (y) a majority-in-interest of the Demanding Holders initiating such Demand Registration thereafter affirmatively elect to continue with such Registration and accordingly notify the Company in writing, but in no event later than five (5) days, of such election; and, provided, further, that the Company shall not be obligated or required to file another Registration Statement until the Registration Statement that has been previously filed with respect to a Registration pursuant to a Demand Registration becomes effective or is subsequently terminated.

2.1.3 Underwritten Offering. Subject to the provisions of subsection 2.1.4 and Section 2.4 hereof, if a majority-in-interest of the Demanding Holders so advise the Company as part of their Demand Registration that the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Offering, then the right of such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such Registration shall be conditioned upon such Holder’s participation in such Underwritten Offering and the inclusion of such Holder’s Registrable Securities in such Underwritten Offering to the extent provided herein. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.1.3 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by a majority-in-interest of the Demanding Holders initiating the Demand Registration.

2.1.4 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Registration pursuant to a Demand Registration, in good faith, advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Holders and the Requesting Holders (if any) desire to sell, taken together with all other shares of Common Stock or other equity securities that the Company desires to sell and the shares of Common Stock, if any, as to which a Registration has been requested pursuant to separate written contractual piggy-back registration rights held by any other stockholders who desire to sell, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, as follows: (i) first, the Registrable Securities of the Demanding Holders and the Requesting Holders (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Holder and Requesting Holder (if any) has requested be included in such Underwritten Registration and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders have collectively requested be included in such Underwritten Registration (such proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Securities; (ii) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (i), the shares of Common Stock or other equity securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Securities; (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Registrable Securities of Holders (Pro Rata, based on the respective number of Registrable Securities that each Holder has so requested) exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1 hereof, which can be sold without exceeding the Maximum Number of Securities; and (iv) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i), (ii) and (iii), the shares of Common Stock or other equity securities of other persons or entities that the Company is obligated to register in a Registration pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities.

Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Registration pursuant to a Demand Registration prior to its withdrawal under this subsection 2.1.5.

2.2 Piggy-back Registration.

2.2.1 Piggy-back Rights. If, at any time on or after the date the Company consummates a Business Combination, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, pursuant to Section 2.1 hereof), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer, as part of a merger, consolidation or similar transaction or for an offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company, or (iv) for a dividend reinvestment plan, then the Company shall give written notice of such proposed filing to all of the Holders of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Holders of Registrable Securities the opportunity to register the sale of such number of Registrable Securities as such Holders may request in writing within five (5) Business Days after receipt of such written notice (such Registration a “Piggy-back Registration”). The Company shall, in good faith, cause such Registrable Securities to be included in such Piggy-back Registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed Underwritten Offering to permit the Registrable Securities requested by the Holders pursuant to this subsection 2.2.1 to be included in a Piggy-back Registration on the same terms and conditions as any similar securities of the Company included in such Registration and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All such Holders proposing to distribute their Registrable Securities through an Underwritten Offering under this subsection 2.2.1 shall enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering by the Company. The Company may postpone or withdraw the filing or the effectiveness of a Piggyback Registration at any time in its sole discretion.

2.2.2 Reduction of Piggy-back Registration. If the managing Underwriter or Underwriters in an Underwritten Registration that is to be a Piggy-back Registration, in good faith, advises the Company and the Holders of Registrable Securities participating in the Piggy-back Registration in writing that the dollar amount or number of the shares of Common Stock that the Company desires to sell, taken together with (i) the shares of Common Stock, if any, as to which Registration has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Holders of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2.1 hereof, and (iii) the shares of Common Stock, if any, as to which Registration has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(a) If the Registration is undertaken for the Company’s account, the Company shall include in any such Registration (A) first, the shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1 hereof, Pro Rata, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock, if any, as to which Registration has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities; and

(b) If the Registration is pursuant to a request by persons or entities other than the Holders of Registrable Securities, then the Company shall include in any such Registration (A) first, the shares of Common Stock or other equity securities, if any, of such requesting persons or entities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Holders exercising their rights to register their Registrable Securities pursuant to subsection 2.2.1, Pro Rata, which can be sold without exceeding the Maximum Number of Securities (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other equity securities that the Company desires to sell which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities.

2.2.3 Piggy-back Registration Withdrawal. Any Holder of Registrable Securities shall have the right to withdraw from a Piggy-back Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggy-back Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggy-back Registration. The Company (in its sole discretion or as the result of a request for withdrawal by persons pursuant to separate written contractual obligations) may postpone or withdraw the filing or effectiveness of a Piggy-back Registration. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with the Piggy-back Registration prior to its withdrawal under this subsection 2.2.3.

2.2.4 Unlimited Piggy-back Registration Rights. For purposes of clarity, any Registration effected pursuant to Section 2.2 hereof shall not be counted as a Registration pursuant to a Demand Registration effected under Section 2.1 hereof; provided, however, that the rights to demand a Piggy-back Registration under this Section 2.2 shall terminate on the second anniversary of the consummation of the Business Combination.

2.3 Registrations on Form S-3. Provided that the Company has qualified for the use of a Registration Statement on Form S-3 or any successor form thereto, any Holder of Registrable Securities may, at any time, and from time to time, request in writing that the Company, pursuant to Rule 415 under the Securities Act (or any successor rule promulgated thereafter by the Commission), register the resale of any or all of their Registrable Securities on Form S-3 or any similar short-form Registration Statement that may be available at such time (“Form S-3”); provided, however, that the Company shall not be obligated to effect such request through an Underwritten Offering. Within ten (10) days of the Company’s receipt of a written request from a Holder or Holders of Registrable Securities for a Registration on Form S-3, the Company shall promptly give written notice of the proposed Registration on Form S-3 to all other Holders of Registrable Securities, and each Holder of Registrable Securities who thereafter wishes to include all or a portion of such Holder’s Registrable Securities in such Registration on Form S-3 shall so notify the Company, in writing, within five (5) days after the receipt by the Holder of the notice from the Company. As soon as practicable thereafter, but not more than thirty (30) days after the Company’s initial receipt of such written request for a Registration on Form S-3, the Company shall file a Registration Statement on Form S-3 with respect to the Registrable Securities of such Holder(s) as are specified in such written request, together with all or such portion of Registrable Securities of any other Holder or Holders joining in such request as are specified in the written notification given by such Holder or Holders, and shall use its reasonable best efforts to cause such Registration Statement to be declared effective by the Commission as soon as practicable thereafter; provided, however, that the Company shall not be obligated to effect any such Registration pursuant to Section 2.3 hereof if (i) a Form S-3 is not available for such offering; or (ii) the Holders of Registrable Securities, together with the Holders of any other equity securities of the Company entitled to inclusion in such Registration, propose to sell the Registrable Securities and such other equity securities (if any) at any aggregate price to the public of less than $10,000,000. The rights to demand Registration on Form S-3 under this Section 2.3 shall terminate on the third anniversary of the Business Combination.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (plus local counsel) for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement 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 or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Holder of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Holder’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Holder under this subsection 4.1.5 shall be limited to the amount of the net proceeds received by such Holder in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in subsections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this subsection 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this subsection 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this subsection 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

5.2 Assignment; No Third Party Beneficiaries.

5.2.1 This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part. Prior to the expiration of the Founder Lock-up Period or Placement Unit Lock-up Period, as the case may be, no Holder may assign or delegate his, her or its rights, duties or obligations under this Agreement in whole or in part. Notwithstanding the above, as it applies to the Registrable Securities, the Holder may transfer such securities during the respective lock-up period to any Permitted Transferee (as such term is defined in that certain Warrant Agreement between the Company and Continental Stock Transfer & Trust Company) but only if such Permitted Transferee agrees to become bound by the transfer restrictions set forth in this Agreement, the Letter Agreement and, if applicable, the Placement Unit Subscription Agreements.

5.2.2 Except as set forth in subsection 5.2.1 hereof, this Agreement and the rights, duties and obligations of the Holders of Registrable Securities hereunder may be assigned or delegated by such Holder of Registrable Securities in conjunction with and to the extent of any transfer of Registrable Securities by any such Holder.

5.2.5 No assignment by any party hereto of such party’s rights, duties and obligations hereunder shall be binding upon or obligate the Company unless and until the Company shall have received (i) written notice of such assignment as provided in Section 5.1 hereof and (ii) the written agreement of the assignee, in a form reasonably satisfactory to the Company, to be bound by the terms and provisions of this Agreement (which may be accomplished by an addendum or certificate of joinder to this Agreement). Any transfer or assignment made other than as provided in this Section 5.2 shall be null and void.

5.3 Counterparts. This Agreement may be executed in multiple counterparts (including facsimile or PDF counterparts), each of which shall be deemed an original, and all of which together shall constitute the same instrument, but only one of which need be produced.

5.4 Governing Law; Venue. THE PARTIES EXPRESSLY AGREE THAT THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED UNDER THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICT OF LAW PROVISIONS OF SUCH JURISDICTION. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in the federal courts of the United States or the courts of the State of New York in each case located in the city of New York, and each party irrevocably submits to the exclusive jurisdiction of such courts in any such suit, action or proceeding.

5.5 Amendments and Modifications. Upon the written consent of the Company and the Holders of at least a majority in interest of the then outstanding Registrable Securities, compliance with any of the provisions, covenants and conditions set forth in this Agreement may be waived, or any of such provisions, covenants or conditions may be amended or modified; provided, however, that notwithstanding the foregoing, any amendment hereto or waiver hereof that adversely affects one Holder, solely in its capacity as a holder of the shares of capital stock of the Company, in a manner that is materially different from the other Holders (in such capacity) shall require the consent of the Holder so affected. No course of dealing between any Holder or the Company and any other party hereto or any failure or delay on the part of a Holder or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Holder or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

5.6 Other Registration Rights. The Company represents and warrants that no person, other than a Holder of Registrable Securities, has any right to require the Company to register any securities of the Company for sale or to include such securities of the Company in any Registration filed by the Company for the sale of securities for its own account or for the account of any other person.

5.7 Termination. This Agreement shall terminate upon the earlier of (i) the fifth anniversary of the date of this Agreement or (ii) the date as of which (A) all of the Registrable Securities have either been sold pursuant to a Registration Statement or cease to be Registrable Securities (but in no event prior to the applicable period referred to in Section 4(3) of the Securities Act and Rule 174 thereunder) or (B) the Holders of all Registrable Securities are permitted to sell the Registrable Securities under Rule 144 (or any similar provision) under the Securities Act without limitation on the amount of securities sold or the manner of sale. The provisions of Section 3.5 and Article IV shall survive any termination.

[SIGNATURE PAGES FOLLOW]

IN WITNESS WHEREOF, the undersigned have caused this Agreement to be executed as of the date first written above.

[Registration Rights Agreement]

Exhibit 10.4

UNIT SUBSCRIPTION AGREEMENT

This UNIT SUBSCRIPTION AGREEMENT (this “Agreement”) is made as of the 17th day of December, 2020, by and between INSU Acquisition Corp. III, a Delaware corporation (the “Company”), having its principal place of business at 2929 Arch Street, Suite 1703, Philadelphia, PA 19104, and Insurance Acquisition Sponsor III, LLC (the “Subscriber”).

WHEREAS, the Company desires to sell on a private placement basis (the “Offering”) an aggregate of 575,000 units (“Units”) of the Company, each Unit comprised of one share of Class A common stock of the Company, par value $0.0001 per share (“Common Stock”), and one third of one warrant to purchase one share of Common Stock (“Warrant”), for a purchase price of $5,750,000, or $10.00 per Unit. The shares of Common Stock underlying the Warrants are hereinafter referred to as the “Warrant Shares.” The shares of Common Stock underlying the Units (excluding the Warrant Shares) are hereinafter referred to as the “Placement Shares.” The Warrants underlying the Units are hereinafter referred to as the “Placement Warrants.” The Units, Placement Shares, Placement Warrants and Warrant Shares, collectively, are hereinafter referred to as the “Securities.” Placement Warrants may be exercised only to the extent that, when aggregated with other Placement Warrants being exercised, the exercise is for a whole share or whole shares; no fractional shares shall be issuable. The exercise price for any Warrant Share shall be $11.50. Subject to the foregoing, the Placement Warrants are exercisable during the period commencing on the later of (i) twelve (12) months from the date of the completion of the Company’s initial public offering of units (the “IPO”) and (ii) 30 days following the consummation of the Company’s initial business combination (the “Business Combination”), as such term is defined in the registration statement filed in connection with the IPO, as amended at the time it becomes effective (the “Registration Statement”), and expiring on the fifth anniversary of the consummation of the Business Combination; and

WHEREAS, Subscriber wishes to purchase the number of Units set forth on Schedule A hereto and the Company wishes to accept such subscription from Subscriber.

NOW, THEREFORE, in consideration of the premises and the mutual covenants hereinafter set forth and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and the Subscriber hereby agree as follows:

1.1 Purchase and Issuance of the Units. Upon the terms and subject to the conditions of this Agreement, Subscriber hereby agrees to purchase from the Company, and the Company hereby agrees to sell to \Subscriber, on the Closing Date (as defined below), 575,000 Units for a purchase price of $5,750,000 (the “Purchase Price”).

1.2 Delivery of the Purchase Price. Upon execution of this Agreement, the Company is bound to fulfill its obligations hereunder and Subscriber hereby irrevocably commits to deliver either directly into a trust account (the “Trust Account”) held at JP Morgan Chase Bank, N.A. or any other financial institution chosen by the Company, with Continental Stock Transfer & Trust Company acting as trustee (“Continental”), or into an escrow account maintained by Ledgewood P.C. (“Ledgewood”), counsel for the Company, the Purchase Price in immediately available funds by wire transfer or such other form of payment as shall be acceptable to the Trustee, in its sole and absolute discretion, one (1) business day prior to the effective date of the Registration Statement.

1.3 Closing. The closing of the Offering (the “Closing”), shall take place at the offices of Ledgewood, simultaneously with the closing of the IPO on or before December 31, 2020 (the “Closing Date”). On the Closing Date, if Subscriber has delivered the Purchase Price to Ledgewood as described in Section 1.2 above, Ledgewood shall wire the purchase price to Continental for deposit in the Trust Account.

1.4 Termination. This Agreement and each of the obligations of the undersigned shall be null and void and without effect if the Closing does not occur prior to December 31, 2020.

Subscriber represents and warrants to the Company that:

2.1 No Government Recommendation or Approval. Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the Company or the Offering of the Securities.

2.2 Accredited Investor. Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that the sale contemplated hereby is being made in reliance, among other things, on a private placement exemption to “accredited investors” under the Securities Act and similar exemptions under state law.

2.3 Intent. Subscriber is purchasing the Securities solely for investment purposes, for Subscriber’s own account (and/or for the account or benefit of its members or affiliates, as permitted, pursuant to the terms of an agreement (the “Letter Agreement”) to be entered into with respect to the Securities between, among others, Subscriber and the Company, as described in the Registration Statement), and not with a view to the distribution thereof and Subscriber has no present arrangement to sell the Securities to or through any person or entity except as may be permitted under the Letter Agreement. Subscriber shall not engage in hedging transactions with regard to the Securities unless in compliance with the Securities Act.

2.4 Restrictions on Transfer. Subscriber acknowledges and understands the Units are being offered in a transaction not involving a public offering in the United States within the meaning of the Securities Act. The Securities have not been registered under the Securities Act and, if in the future Subscriber decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other jurisdiction. Notwithstanding the foregoing, Subscriber acknowledges and understands the Securities are subject to transfer restrictions as described in Section 8 hereof. Subscriber agrees that, if any transfer of its Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company with respect to such transfer. Absent registration or another available exemption from registration, Subscriber agrees it will not transfer the Securities (unless otherwise permitted pursuant to the Letter Agreement, as described in the Registration Statement). Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to Subscriber for the resale of the Securities until the one year anniversary following consummation of the Business Combination, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions.

2.5 Sophisticated Investor.

(i) Subscriber’s manager and members are individually accredited investors and are sophisticated in financial matters and able to evaluate the risks and benefits of the investment in the Securities.

(ii) Subscriber is aware that an investment in the Securities is highly speculative and subject to substantial risks because, among other things, (a) the Securities are subject to transfer restrictions and have not been registered under the Securities Act and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available and (b) Subscriber has waived its redemption rights with respect to the Securities as set forth in Section 5 hereof, and the Securities held by Subscriber are not entitled to, and have no right, interest or claim to any monies held in the Trust Account, and accordingly Subscriber may suffer a loss of a portion or all of its investment in the Securities. Subscriber is able to bear the economic risk of its investment in the Securities for an indefinite period of time.

2.6 Independent Investigation. Subscriber, in making the decision to purchase the Units, has relied upon an independent investigation of the Company and has not relied upon any information or representations made by any third parties or upon any oral or written representations or assurances from the Company, its officers, directors or employees or any other representatives or agents of the Company, other than as set forth in this Agreement. Subscriber is familiar with the business, operations and financial condition of the Company and has had an opportunity to ask questions of, and receive answers from the Company’s officers and directors concerning the Company and the terms and conditions of the Offering and has had full access to such other information concerning the Company as Subscriber has requested. Subscriber confirms that all documents that it has requested have been made available and that Subscriber has been supplied with all of the additional information concerning this investment which Subscriber has requested.

2.7 Organization and Authority. Subscriber is duly organized, validly existing and in good standing under the laws of the State of Delaware and it possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

2.8 Authority. This Agreement has been validly authorized, executed and delivered by Subscriber and is a valid and binding agreement enforceable in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization, or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by equitable principles of general application and except as enforcement of rights to indemnity and contribution may be limited by federal and state securities laws or principles of public policy.

2.9 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) Subscriber’s charter documents, (ii) any agreement or instrument to which Subscriber is a party or (iii) any law, statute, rule or regulation to which Subscriber is subject, or any agreement, order, judgment or decree to which Subscriber is subject.

2.10 No Legal Advice from Company. Subscriber acknowledges it has had the opportunity to review this Agreement and the transactions contemplated by this Agreement and the other agreements entered into between the parties hereto with Subscriber’s own legal counsel and investment and tax advisors. Except for any statements or representations of the Company made in this Agreement and the other agreements entered into between the parties hereto, Subscriber is relying solely on such review, counsel and advisors and not on any statements or representations of the Company or any of its representatives or agents for legal, tax or investment advice with respect to this investment, the transactions contemplated by this Agreement or the securities laws of any jurisdiction.

2.11 Reliance on Representations and Warranties. Subscriber understands the Units are being offered and sold to Subscriber in reliance on exemptions from the registration requirements under the Securities Act, and analogous provisions in the laws and regulations of various states, and that the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of Subscriber set forth in this Agreement in order to determine the applicability of such provisions.

2.12 No General Solicitation. Subscriber is not subscribing for the Units as a result of or subsequent to any general solicitation or general advertising, including but not limited to any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media or broadcast over television or radio, or presented at any seminar or meeting or in a registration statement with respect to the IPO filed with the Securities and Exchange Commission (“SEC”).

2.13 Legend. Subscriber acknowledges and agrees the certificates evidencing each of the Securities shall bear a restrictive legend (the “Legend”), in form and substance substantially as set forth in Section 4 hereof.

The Company represents and warrants to, and agrees with, Subscriber that:

3.1 Valid Issuance of Capital Stock. The total number of shares of all classes of capital stock which the Company has authority to issue is 70,000,000 shares of Common Stock and 1,000,000 shares of preferred stock, $0.0001 par value per share (“Preferred Stock”). As of the date hereof, the Company has issued and outstanding 8,548,333 shares of Class B common stock, par value $0.0001 per share (of which up to 1,090,000 shares are subject to forfeiture) and no shares of Preferred Stock. All of the issued shares of capital stock of the Company have been duly authorized, validly issued, and are fully paid and non-assessable.

3.2 Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement (as defined in Section 8.1), as the case may be, each of the Units, Placement Shares, Placement Warrants and the Warrant Shares will be duly and validly issued, fully paid and non-assessable. On the date of issuance of the Units, the Warrant Shares shall have been reserved for issuance. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the Warrant Agreement, as the case may be, Subscriber will have or receive good title to the Units, Placement Shares and Placement Warrants, free and clear of all liens, claims and encumbrances of any kind resulting from actions of, or any failure to act by, the Company, other than (i) transfer restrictions hereunder and pursuant to the Letter Agreement and (ii) transfer restrictions under federal and state securities laws.

3.3 Organization and Qualification. The Company is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware and has the requisite corporate power to own its properties and assets and to carry on its business as now being conducted.

3.4 Authorization; Enforcement. (i) The Company has the requisite corporate power and authority to enter into and perform its obligations under this Agreement and to issue the Securities in accordance with the terms hereof, (ii) the execution, delivery and performance of this Agreement by the Company and the consummation by it of the transactions contemplated hereby have been duly authorized by all necessary corporate action, and no further consent or authorization of the Company or its Board of Directors or stockholders is required, and (iii) this Agreement constitutes a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance, moratorium, reorganization, or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by equitable principles of general application and except as enforcement of rights to indemnity and contribution may be limited by federal and state securities laws or principles of public policy.

3.5 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Company of the transactions contemplated hereby do not (i) result in a violation of the Company’s certificate of incorporation or by-laws, (ii) conflict with, or constitute a default under any agreement or instrument to which the Company is a party or by which it is bound or (iii) violate any law statute, rule or regulation to which the Company is subject or any agreement, order, judgment or decree to which the Company is subject. Other than any SEC or state securities filings which may be required to be made by the Company subsequent to the Closing, and any registration statement which may be filed pursuant thereto, the Company is not required under federal, state or local law, rule or regulation to obtain any consent, authorization or order of, or make any filing or registration with, any court or governmental agency or self-regulatory entity in order for it to perform any of its obligations under this Agreement or issue the Units, Placement Shares, Placement Warrants or the Warrant Shares in accordance with the terms hereof.

4.1 Legend. The Company will issue the Units, Placement Shares and Placement Warrants, and, when issued, the Warrant Shares, purchased by Subscriber in the name of Subscriber. The Securities will bear the following Legend and appropriate “stop transfer” instructions:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY STATE SECURITIES LAWS AND NEITHER THESE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL FOR THIS CORPORATION, IS AVAILABLE.”

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER PURSUANT TO A LETTER AGREEMENT AMONG INSU ACQUISITION CORP. III AND THE OTHER PARTIES THERETO AND MAY ONLY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF DURING THE TERM THEREOF PURSUANT TO THE TERMS SET FORTH IN THE LETTER AGREEMENT.”

4.2 Subscriber’s Compliance. Nothing in this Section 4 shall affect in any way Subscriber’s obligations and agreements to comply with all applicable securities laws upon resale of the Securities.

4.3 Company’s Refusal to Register Transfer of the Securities. The Company shall refuse to register any transfer of the Securities if, in the sole judgment of the Company, such purported transfer would not be made (i) pursuant to an effective registration statement filed under the Securities Act, or (ii) pursuant to an available exemption from the registration requirements of the Securities Act and applicable state securities laws and (iii) in compliance herewith and with the Letter Agreement.

4.4 Registration Rights. Subscriber will be entitled to certain registration rights which will be governed by a registration rights agreement (“Registration Rights Agreement”) to be entered into between, among others, Subscriber and the Company, on or prior to the effective date of the Registration Statement.

In connection with the Securities purchased pursuant to this Agreement, Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions with respect to the Securities in connection with (i) the exercise of redemption rights in connection with the Company’s consummation of the Business Combination, or (ii) upon the Company’s redemption of shares of Common Stock upon the Company’s failure to consummate the Business Combination within 24 months from the completion of the IPO or the liquidation of the Company prior to the expiration of such 24 month period. In the event any Subscriber purchases shares of Common Stock in the IPO or in the aftermarket (“Public Shares”), Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions with respect to any Public Shares in connection with the exercise of redemption rights in connection with the Company’s consummation of the Business Combination. For the avoidance of doubt, Subscriber shall be eligible to redeem any Public Shares upon the same terms offered to all other purchasers of Common Stock in the IPO in the event the Company fails to consummate the Business Combination, or liquidates, within 24 months from the completion of the IPO.

6.1 Failure to Consummate Business Combination. The Placement Warrants shall be terminated upon the dissolution of the Company or in the event that the Company does not consummate the Business Combination within 24 months from the completion of the IPO.

6.2 Termination of Rights as Holder. If the Placement Warrants are terminated in accordance with Section 6.1, then after such time, Subscriber (or successor in interest) shall no longer have any rights as holders of such Placement Warrants and the Company shall take such action as is appropriate to cancel such Placement Warrants. Subscriber hereby irrevocably grants the Company a limited power of attorney for the purpose of effectuating the foregoing and agrees to take any and all measures reasonably requested by the Company necessary to effect the foregoing.

7.1 Subscriber understands and acknowledges an exemption from the registration requirements of the Securities Act requires there be no general solicitation of purchasers of the Units. In this regard, if the IPO were deemed to be a general solicitation with respect to the Units, the offer and sale of such Units may not be exempt from registration and, if not, the Subscriber may have a right to rescind their purchases of the Units. In order to facilitate the completion of the Offering and in order to protect the Company, its stockholders and the amounts in the Trust Account from claims that may adversely affect the Company or the interests of its stockholders, Subscriber hereby agrees to waive, to the maximum extent permitted by applicable law, any claims, right to sue or rights in law or arbitration, as the case may be, to seek rescission of its purchase of the Units. Subscriber acknowledges and agrees this waiver is being made in order to induce the Company to sell the Units to Subscriber. Subscriber agrees the foregoing waiver of rescission rights shall apply to any and all known or unknown actions, causes of action, suits, claims or proceedings (collectively, “Claims”) and related losses, costs, penalties, fees, liabilities and damages, whether compensatory, consequential or exemplary, and expenses in connection therewith, including reasonable attorneys’ and expert witness fees and disbursements and all other expenses reasonably incurred in investigating, preparing or defending against any Claims, whether pending or threatened, in connection with any present or future actual or asserted right to rescind the purchase of the Units hereunder or relating to the purchase of the Units and the transactions contemplated hereby.

7.2 Subscriber agrees not to seek recourse against the Trust Account for any reason whatsoever in connection with its purchase of the Units or any Claim that may arise now or in the future.

7.3 Subscriber acknowledges and agrees that the stockholders of the Company are and shall be third-party beneficiaries of this Section 7.

7.4 Subscriber agrees that, to the extent any waiver of rights under this Section 7 is ineffective as a matter of law, Subscriber has offered such waiver for the benefit of the Company as an equitable right that shall survive any statutory disqualification or bar that applies to a legal right. Subscriber acknowledges the receipt and sufficiency of consideration received from the Company hereunder in this regard.

The Units and their component parts are substantially identical to the units to be offered in the IPO except that: (i) the Units and their component parts will be subject to transfer restrictions, except in limited circumstances, until 30 days following the consummation of the Business Combination, (ii) the Placement Warrants will be non-redeemable so long as they are held by a Subscriber (or any of its permitted transferees), and will be exercisable on a “cashless” basis if held by Subscriber or its permitted transferees and (iii) the Units and their component parts are being purchased pursuant to an exemption from the registration requirements of the Securities Act and will become freely tradable only after they are registered or an exemption from registration is available, and the restrictions described above in clause (i) have expired.

This Agreement shall be governed by and construed in accordance with the laws of the State of New York for agreements made and to be wholly performed within such state. The parties hereto hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby.

10.1 Assignment. Neither this Agreement nor any rights hereunder may be assigned by any party to any other person other than by a Subscriber to a person agreeing to be bound by the terms hereof, including the waiver contained in Section 7 hereof.

10.2 Entire Agreement. This Agreement sets forth the entire agreement and understanding between the parties as to the subject matter hereof and merges and supersedes all prior discussions, agreements and understandings of any and every nature among them.

10.3 Amendment. Except as expressly provided in this Agreement, neither this Agreement nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument signed by the party against whom enforcement of any such amendment, waiver, discharge or termination is sought.
