Agreement

1. Sale and Purchase.

(a) Forward Purchase Shares.

(i) Subject to Sections 1(a)(ii), (iii), and (iv) hereof, the Company shall issue and sell to the Purchaser or Purchasers, determined as set forth in Section 1(a)(ii)(B) hereof, and the Purchaser or Purchasers shall purchase from the Company, up to an aggregate maximum of 7,500,000 Forward Purchase Shares (the “Maximum Shares”), for a purchase price of $10.00 per Forward Purchase Share (the “Forward Purchase Price”), or up to a maximum of $75,000,000 in the aggregate.

(ii) The number of Forward Purchase Shares to be issued and sold by the Company and purchased by each Purchaser hereunder shall be determined as follows:

(A) As soon as reasonably practicable, but in no event less than fifteen (15) Business Days prior to the Company’s entry into the Definitive Agreement, the Company shall provide the Advisor with notice (the “Initial Company Notice”) of the number of Forward Purchase Shares desired to be issued and sold by the Company pursuant to this Agreement. Such number of Forward Purchase Shares shall be determined by the Company, in its sole discretion, based on, but not limited to, the Cash Requirements and the Available Cash; provided, however, that such number shall in no event exceed the Maximum Shares. Following delivery of the Initial Company Notice, the Company shall provide the Advisor with such other information as the Advisor (or any applicable Transferee pursuant to Section 6(b) hereof) may reasonably request so that the Advisor may appropriately determine the allocation of the Forward Purchase Shares pursuant to Section 1(a)(ii)(C) hereof.

(B) Subject to Section 1(a)(ii)(C) hereof, within ten (10) Business Days after receipt of the Initial Company Notice, the Advisor shall (i) allocate to one or more Clients or, in lieu of allocating to a Client, assign to one or more third parties (together with the Clients, the “Purchasers” and individually, a “Purchaser”), in whole or in part, the obligation to purchase the Forward Purchase Shares set forth in the Initial Company Notice and (ii) provide the Company with notice (the “Initial Purchaser Notice”) of the identity of each Purchaser and the number of Forward Purchase Shares it has allocated or assigned to each Purchaser pursuant to this Agreement, if any, which shall not exceed the Maximum Shares. Upon such allocation or assignment:

1. such Purchaser shall execute a signature page to this Agreement, substantially in the form attached as Exhibit A hereto (a “Purchaser Joinder”), which shall reflect the number of Forward Purchase Shares to be purchased by such Purchaser and shall constitute the binding obligation of such Purchaser to purchase such Forward Purchase Shares, subject to the terms and conditions of this Agreement, and, upon such execution, such Purchaser shall have all the rights and obligations of a Purchaser hereunder with respect to such Forward Purchase Shares and shall make all of the representations, warranties, covenants and agreements of a Purchaser hereunder, and references herein to the “Purchaser” shall be deemed to refer to such Purchaser and to its Forward Purchase Shares; provided, that any representations, warranties, covenants and agreements of such Purchaser and any other Purchaser shall be several and not joint and shall be made as to such Purchaser or any other Purchaser, as applicable, as to itself only; provided, further, that notwithstanding anything to the contrary contained herein, to the extent the Company proposes to obtain alternative financing to fund the initial Business Combination in the form of an offering of New Equity Securities (“Alternative Financing”) and a Purchaser participates in such Alternative Financing pursuant to Section 5 hereof, the aggregate commitment hereunder shall be reduced by the amount of such Purchaser’s participation in such Alternative Financing; and

2. upon a Purchaser’s execution and delivery of a Purchaser Joinder, the number of Forward Purchase Shares to be purchased by such Purchaser hereunder shall be reflected in Schedule A to this Agreement. For the avoidance of doubt, this Agreement need not be amended and restated in its entirety, but only Schedule A need be completed by each of the Purchaser and the Company upon the occurrence of any such allocation of the Forward Purchase Shares.

(C) Notwithstanding the foregoing, the Advisor shall only be obligated to allocate the purchase of some or all of the number of Forward Purchase Shares set forth in the Initial Company Notice to any Client if and only if: (i) the initial Business Combination is proposed to be consummated with a company engaged in a business that is within the investment objectives of such Client; and (ii) the initial Business Combination, including the target assets or business, and the terms of the initial Business Combination, are reasonably acceptable to such Client, as determined by the Advisor in its sole discretion (it being understood that the Advisor may consider many of the same criteria as the Company will consider, but will also consider whether the investment is an appropriate investment for such Client, including whether the investment complies with any guidelines, restrictions or conflicts of interest provisions applicable to such Client), and if not all of the Forward Purchase Shares set forth in the Initial Company Notice are allocated to Clients, the Advisor may, but shall not be obligated to, assign the obligation to purchase such Forward Purchase Shares to one or more third parties. The Company acknowledges that this Agreement is neither a commitment nor an obligation of any Client to purchase any Forward Purchase Shares, unless otherwise expressly agreed in writing by such Client by execution and delivery of a Purchaser Joinder.

(iii) At least two (2) Business Days before the Business Combination Closing, the Company shall provide each Purchaser with an updated notice (the “Final Company Notice”) including:

(A) its determination of the number of Forward Purchase Shares that it desires each Purchaser to purchase pursuant to this Agreement;

(B) the anticipated date of the Business Combination Closing; and

(iv) At least one (1) Business Day before the Business Combination Closing, each Purchaser shall provide the Company with an updated notice (the “Final Purchaser Notice”) of the number of Forward Purchase Shares it will be obligated to purchase pursuant to this Agreement, with no further notification or confirmation necessary from the Company, which number shall not be less than the lesser of (A) the number of Forward Purchase Shares that such Purchaser was obligated to purchase pursuant to such Purchaser’s Purchaser Joinder and (B) the number of Forward Purchase Shares that the Company desires the Purchaser to purchase as specified in the Final Company Notice.

(v) The closing of the sale of Forward Purchase Shares (the “Forward Closing”) shall be held on the same date and concurrently with the Business Combination Closing (such date being referred to as the “Forward Closing Date”). At least one (1) Business Day prior to the Forward Closing Date, the Purchaser shall deliver to the Company the aggregate Forward Purchase Price for the Forward Purchase Shares by wire transfer of U.S. dollars in immediately available funds to the account specified by the Company in such notice to be held in escrow until the Forward Closing. Immediately prior to the Forward Closing on the Forward Closing Date, (i) the aggregate Forward Purchase Price shall be released from escrow automatically and without further action by the Company or the Purchaser, and (ii) upon such release, the Company shall issue the Forward Purchase Shares to the Purchaser in book-entry form, free and clear of any liens or other restrictions whatsoever (other than those arising under state or federal securities laws), registered in the name of the Purchaser (or its nominee in accordance with its delivery instructions), or to a custodian designated by the Purchaser, as applicable. In the event the Business Combination Closing does not occur within five (5) Business Days of the date scheduled for closing, the Forward Closing shall not occur and the Company shall promptly (but not later than one (1) Business Day thereafter) return the aggregate Forward Purchase Price to the Purchaser. For purposes of this Agreement, “Business Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close in the City of New York, New York.

(b) Legends. Each register and book entry for the Forward Purchase Shares shall contain a notation, and each certificate (if any) evidencing the Forward Purchase Shares shall be stamped or otherwise imprinted with a legend, in substantially the following form:

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.

This Agreement, when executed and delivered by the Purchaser, will constitute the valid and legally binding obligation of the Purchaser, enforceable against the Purchaser in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies, or (iii) to the extent the indemnification provisions contained in the Registration Rights (as defined below) may be limited by applicable federal or state securities laws.

(c) Governmental Consents and Filings. No consent, approval, order or authorization of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Purchaser in connection with the consummation of the transactions contemplated by this Agreement.

(d) Compliance with Other Instruments. The execution, delivery and performance by the Purchaser of this Agreement and the consummation by the Purchaser of the transactions contemplated by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents, (ii) of any instrument, judgment, order, writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement, contract or purchase order to which it is a party or by which it is bound or (v) of any provision of federal or state statute, rule or regulation applicable to the Purchaser, in each case (other than clause (i)), which would have a material adverse effect on the Purchaser or its ability to consummate the transactions contemplated by this Agreement.

(e) Purchase Entirely for Own Account. This Agreement is made with the Purchaser in reliance upon the Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Forward Purchase Shares to be acquired by the Purchaser will be acquired for investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof in violation of any state or federal securities laws, and that the Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same in violation of law. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any of the Forward Purchase Shares.

(g) Restricted Securities. The Purchaser understands that the offer and sale of the Forward Purchase Shares to the Purchaser has not been, and will not be, registered under the Securities Act of 1933, as amended (the “Securities Act”), by reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed herein.

The Purchaser acknowledges that the Company has no obligation to register or qualify the Forward Purchase Shares, or any Class A Shares into which the Forward Purchase Shares may be converted or exercised, for resale, except for the Registration Rights. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Forward Purchase Shares, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is under no obligation and may not be able to satisfy. The Purchaser acknowledges that the Company filed the Registration Statement for its proposed IPO. The Purchaser understands that the offering of the Forward Purchase Shares is not, and is not intended to be, part of the IPO, and that the Purchaser will not be able to rely on the protection of Section 11 of the Securities Act with respect to the Forward Purchase Shares.

(h) No Public Market. The Purchaser understands that no public market now exists for the Forward Purchase Shares, and that the Company has made no assurances that a public market will ever exist for the Forward Purchase Shares.

(l) Residence. The Purchaser’s principal place of business is the office or offices located at the address of the Purchaser set forth on the signature page hereof.

(m) Non-Public Information. The Purchaser acknowledges its obligations under applicable securities laws with respect to the treatment of non-public information relating to the Company.

5. Right of First Offer. Subject to the terms and conditions of this Section 5, if, in connection with or prior to the Business Combination Closing, the Company proposes to issue any equity securities, or securities convertible into, exchangeable or exercisable for equity securities, other than the Public Units (and their component Public Shares and Public Warrants) and the Excluded Securities (as defined below) (“New Equity Securities”), or offer or seek commitments for any New Equity Securities to backstop any such capital raise, the Company shall first make an offer of the New Equity Securities to the Advisors on behalf of their respective Clients or other Purchasers in accordance with the following provisions of this Section 5:

(a) Offer Notice.

(i) The Company shall give written notice (the “Offering Notice”) to the Advisors stating its bona fide intention to offer the New Equity Securities and specifying the number of New Equity Securities and the material terms and conditions, including the price, pursuant to which the Company proposes to offer the New Equity Securities and the applicable pro rata share of such New Equity Securities offered to each of the Advisors pursuant to such Offering Notice, which shall be 50% of such New Equity Securities.

(ii) The Offering Notice shall constitute the Company’s offer to sell the New Equity Securities to Clients managed by the Advisors or other Purchasers, which offer shall be irrevocable for a period of ten (10) Business Days (the “ROFO Notice Period”).

(b) Exercise of Right of First Offer.

(i) Upon receipt of the Offering Notice, the Advisors shall have until the end of the ROFO Notice Period to accept the Company’s offer to purchase, in whole or in part, its pro rata share of the New Equity Securities by delivering a written notice (a “ROFO Notice”) to the Company stating that it accepts, on behalf of one or more specified Clients or other Purchasers, the Company’s offer to purchase such New Equity Securities on the terms specified in the Offering Notice and in the amounts specified in the ROFO Notice. Any ROFO Notice signed by the Clients or other Purchasers named therein and so delivered shall be binding upon delivery and irrevocable by such Clients or other Purchasers.

(ii) If one of the Advisors does not deliver a ROFO Notice during the ROFO Notice Period accepting all of the New Equity Securities offered to it, it shall be deemed to have waived on behalf of its Clients or other Purchasers all rights to purchase the New Equity Securities offered pursuant to the Offering Notice under this Section 5 that were not included in the ROFO Notice (the “Waived New Equity Securities”). Thereafter, to the extent the other Advisor has delivered a ROFO Notice to the Company during the ROFO Notice Period accepting the Company’s initial offer to purchase all of the New Equity Securities offered to it, the Company shall, within five (5) Business Days after the expiration of the ROFO Notice Period, give an Offering Notice to such Advisor, informing it that it has the right to increase the number of New Equity Securities that it accepted pursuant to the initial ROFO Notice by up to the number of Waived New Equity Securities. Such Advisor shall then have two (2) Business Days (the “Subsequent Offering Period”) in which to accept such second offer, by giving notice of acceptance (the “Subsequent ROFO Notice”) to the Company prior to the expiration of the Subsequent Offering Period, as to portion of the Waived New Equity Securities it accepts for purchase on behalf of one or more specified Clients or other Purchasers.

(iii) If the Subsequent Offer Notice is not delivered to the Company prior to the expiration of the Subsequent Offering Period accepting for purchase all of the Waived New Equity Securities, the applicable Advisor shall be deemed to have waived on behalf of its Clients and other Purchasers all rights to purchase such Waived New Equity Securities in such second offer by the Company that it did not accept for purchase. The Company shall thereafter be free to sell or enter into an agreement to sell the unaccepted portion of such Waived New Equity Securities to any third party without any further obligation to the Advisors pursuant to this Section 5 within the ninety (90) day period thereafter (and with respect to an agreement to sell, consummate such sale at any time thereafter) on terms and conditions not more favorable to the third party than those set forth in any Offering Notice. If the Company does not sell or enter into an agreement to sell the unaccepted portion of the New Equity Securities within such period, the rights provided hereunder shall be deemed to be revived and the New Equity Securities shall not be offered to any third party unless first re-offered to the Advisors in accordance with this Section 5.

(c) Excluded Securities. For purposes hereof, the term “Excluded Securities” means Class B Shares (and Class A Shares for which such Class B Shares are convertible) issued to the Sponsor prior to the IPO, private placement warrants issued by the Company in connection with the IPO for $1.50 per warrant for an aggregate of $9,700,000 (or $10,855,000 if the underwriters’ over-allotment option is exercised in full) and which have the same exercise price as the Warrants (“Private Placement Warrants”) issued pursuant to a private placement agreement by and among the Company and the parties thereto (the “Private Placement Warrant Agreement”), working capital loans to the Company to finance transaction costs in connection with an intended initial Business Combination to the extent they may be convertible at the option of the lender into warrants of the post- initial Business Combination entity (“Working Capital Loans”)), warrants issued upon the conversion of Working Capital Loans, any securities issued by the Company as consideration to any seller in the initial Business Combination and any Class A Shares issued pursuant to this Agreement or the Other Forward Contract.

(d) Additional Private Placements. Notwithstanding anything to the contrary contained herein, prior to the IPO, the Company will not issue or agree to issue any securities (other than Forward Purchase Shares contemplated by this Agreement, the Other Forward Contract, the Private Placement Warrants and the Public Units) without the Advisors’ prior written consent.

6. Registration Rights; Transfer

(a) Registration Rights. Each Purchaser shall be granted registration rights by the Company with respect to the Forward Purchase Shares pursuant to the registration rights agreement (the “Registration Rights Agreement”) to be entered into by the Company in connection with its IPO, a form of which has been filed with the registration statement relating to the Company’s IPO (the “Registration Rights”). Upon a Purchaser’s entry into a Purchaser Joinder, such Purchaser shall execute a joinder to the Registration Rights Agreement.

(b) Transfer. This Agreement and all of the Purchaser’s rights and obligations hereunder (including the Purchaser’s obligation to purchase the Forward Purchase Shares) may be transferred or assigned, at any time and from time to time, in whole or in part, to a Forward Contract Party or one or more third parties (each such transferee, a “Transferee”). Upon any such assignment:

(i) the applicable Transferee shall execute a signature page to this Agreement, substantially in the form of the Purchaser’s signature page hereto (the “Transferee Joinder Agreement”), which shall reflect the number of Forward Purchase Shares to be purchased by such Transferee (the “Transferee Securities”), and, upon such execution, such Transferee shall have all the same rights and obligations of the Purchaser hereunder with respect to the Transferee Securities, and references herein to the “Purchaser” shall be deemed to refer to and include any such Transferee with respect to such Transferee and to its Transferee Securities; provided, that any representations, warranties, covenants and agreements of the Purchaser and any such Transferee shall be several and not joint and shall be made as to the Purchaser or any such Transferee, as applicable, as to itself only; and

(ii) upon a Transferee’s execution and delivery of a Transferee Joinder Agreement, the number of Forward Purchase Shares to be purchased by the Purchaser hereunder shall be reduced by the total number of Forward Purchase Shares to be purchased by the applicable Transferee pursuant to the applicable Transferee Joinder Agreement, which reduction shall be evidenced by the Purchaser and the Company amending Schedule A and Schedule B to this Agreement to reflect each transfer and updating the “Number of Forward Purchase Shares” and “Aggregate Purchase Price for Forward Purchase Shares” on the Purchaser’s signature page hereto to reflect such reduced number of Forward Purchase Shares, and the Purchaser shall be fully and unconditionally released from its obligation to purchase such Transferee Securities hereunder. For the avoidance of doubt, this Agreement need not be amended and restated in its entirety, but only Schedule A and Schedule B and the Purchaser’s signature page hereto need be so amended and updated and executed by each of the Purchaser and the Company upon the occurrence of any such transfer of Transferee Securities.

7. Additional Agreements, Acknowledgements and Waivers of the Purchaser.

(a) Lock-up; Transfer Restrictions. The Purchaser agrees that it shall not Transfer any Forward Purchase Shares until 30 days after the completion of the initial Business Combination. Notwithstanding the foregoing, Transfers of the Forward Purchase Shares are permitted (any such transferees, the “Permitted Transferees”): (A) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Purchaser, or any affiliates of the Purchaser; (B) in the case of an individual, by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of individual’s immediate family or an affiliate of such person, or to a charitable organization; (C) in the case of an individual, by virtue of 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 a Business Combination at prices no greater than the price at which the securities were originally purchased; (F) in the event of the Company’s liquidation prior to the completion of a Business Combination; (G) 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 Class A Shares for cash, securities or other property subsequent to the completion of the initial Business Combination; (H) as a distribution to limited partners, members or stockholders of the Purchaser; (I) to the Purchaser’s affiliates, to any investment fund or other entity controlled or managed by the Purchaser or any of its affiliates, or to any investment manager or investment advisor of the Purchaser or an affiliate of any such investment manager or investment advisor; (J) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (A) through (I) above; (K) to the Purchaser or any Transferee hereunder; (L) by virtue of the laws of the Purchaser’s jurisdiction of formation or its organizational documents upon dissolution of the Purchaser; and (M) pursuant to an order of a court or regulatory agency; provided, however, that in the case of clauses (A) through (E) and (H) through (L), these Permitted Transferees must enter into a written agreement agreeing to be bound by these transfer restrictions. “Transfer” shall mean the (x) sale or assignment of, offer to sell, contract or agreement to sell, hypothecation, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position (within the meaning of Section 16 of the Exchange Act, and the rules and regulations of the SEC promulgated thereunder) with respect to, any of the Forward Purchase Shares (excluding any pledges in the ordinary course of business for bona fide financing purposes or as part of prime brokerage arrangements), (y) entry 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 Forward Purchase Shares, whether any such transaction is to be settled by delivery of such Forward Purchase Shares, in cash or otherwise, or (z) public announcement of any intention to effect any transaction specified in clause (x) or (y).

(b) Trust Account.

(i) The Purchaser hereby acknowledges that it is aware that the Company will establish the Trust Account for the benefit of its public stockholders upon the IPO Closing. The Purchaser, for itself and its affiliates, hereby agrees that it has no right, title, interest or claim of any kind in or to any monies held in the Trust Account, or any other asset of the Company as a result of any liquidation of the Company, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it.

(ii) The Purchaser hereby agrees that it shall have no right of set-off or any right, title, interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it. In the event the Purchaser has any Claim against the Company under this Agreement, the Purchaser shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the property or any monies in the Trust Account, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it.

8. Nasdaq Listing. The Company will use commercially reasonable efforts to effect the listing of the Units, Class A Shares and Public Warrants on The Nasdaq Capital Market (“Nasdaq”) (or another national securities exchange) at the time of the Business Combination Closing.

(iv) The representations and warranties of the Company set forth in Section 4 of this Agreement shall have been true and correct as of the date hereof and shall be true and correct as of the Forward Closing Date, as applicable, with the same effect as though such representations and warranties had been made on and as of such date (other than any such representation or warranty that is made by its terms as of a specified date, which shall be true and correct as of such specified date), except where the failure to be so true and correct would not have a material adverse effect on the Company or its ability to consummate the transactions contemplated by this Agreement;

(v) The Company shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Company at or prior to the Forward Closing; and

(iii) The Purchaser shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions required by this Agreement to be performed, satisfied or complied with by the Purchaser at or prior to the Forward Closing; and

(iv) No order, writ, judgment, injunction, decree, determination, or award shall have been entered by or with any governmental, regulatory, or administrative authority or any court, tribunal, or judicial, or arbitral body, and no other legal restraint or prohibition shall be in effect, preventing the purchase by the Purchaser of the Forward Purchase Shares.

10. Termination. This Agreement may be terminated at any time prior to the Forward Closing:

(a) by mutual written consent of the Company and the Purchaser;

(b) automatically

(i) if the IPO is not consummated on or prior to twelve months from the date of this Agreement; or

(ii) if a Business Combination is not consummated within 24 months from the closing of the IPO, or such later date as may be approved by the Company’s stockholders.

In the event of any termination of this Agreement pursuant to this Section 10, the Forward Purchase Price (and interest thereon, if any), if previously paid with respect to any Forward Purchase Shares, and all Purchaser’s funds paid in connection herewith shall be promptly returned to the Purchaser, and thereafter this Agreement shall forthwith become null and void and have no effect, without any liability on the part of the Purchaser or the Company and their respective directors, officers, employees, partners, managers, members, or stockholders and all rights and obligations of each party shall cease; provided, however, that nothing contained in this Section 10 shall relieve either party from liabilities or damages arising out of any fraud or willful breach by such party of any of its representations, warranties, covenants or agreements contained in this Agreement.

(f) Assignments. Except as otherwise specifically provided herein, no party hereto may assign either this Agreement or any of its rights, interests, or obligations hereunder without the prior written approval of the other party.

(g) Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument.

(h) Headings. The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

(i) Governing Law. This Agreement, the entire relationship of the parties hereto, and any dispute between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of New York, without giving effect to its choice of laws principles.

(j) Jurisdiction.

(l) Amendments. This Agreement may not be amended, modified or waived as to any particular provision except with the prior written consent of the Company and the Purchaser.

(m) Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided, that if any provision of this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a governmental authority, arbitrator, or mediator not to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.

(n) Expenses.

(o) Construction. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.

(p) Waiver. No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent occurrence.

(q) Specific Performance. The Purchaser agrees that irreparable damage may occur in the event any provision of this Agreement was not performed by the Purchaser in accordance with the terms hereof and that the Company shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or equity.
