Agreement

1. Sale and Purchase.

(a) Forward Purchase Securities.

(i) The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, that number of Class A Shares (the “Forward Purchase Shares”), up to a maximum of 40,000,000 Class A Shares (the “Maximum Shares”), plus that number of warrants (the “Forward Purchase Warrants” and, together with the Forward Purchase Shares, the “Forward Purchase Securities”), up to a maximum of 13,333,333 warrants) (the “Maximum Warrants”), in each case determined as set forth in clause 1(a)(ii), for an aggregate purchase price of $10.00 per unit (the “Forward Purchase Price”) of one Forward Purchase Share and one-third of one Forward Purchase Warrant (each, a “Forward Purchase Unit”), or up to a maximum of $400,000,000 in the aggregate.

(ii) The number of Forward Purchase Units to be issued and sold by the Company and purchased by the Purchaser hereunder shall equal that number which, after payment of the aggregate Forward Purchase Price by the Purchaser, will result in gross proceeds to the Company in an aggregate amount equal to the amount of funds necessary for the Company to consummate the Business Combination and pay related fees and expenses, less amounts available to the Company from the Trust Account (after payment of the deferred underwriting discount and after giving effect to any redemptions of Public Shares) and any other financing source obtained by the Company for such purpose at or prior to the consummation of the Business Combination, plus any additional amounts mutually agreed by the Company and the Purchaser that may be retained by the post-Business Combination company for working capital or other purposes, but in no event shall the number of Forward Purchase Shares or Forward Purchase Warrants purchased hereunder exceed the Maximum Shares or the Maximum Warrants, respectively.

(iii) Each Forward Purchase Warrant will have the same terms as each Private Placement Warrant, and will be subject to the terms and conditions of the Warrant Agreement to be entered into between the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, in connection with the IPO (the “Warrant Agreement”). Each Forward Purchase Warrant will entitle the holder thereof to purchase one Class A Share at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement, and only whole Forward Purchase Warrants will be exercisable. The Forward Purchase Warrants will become exercisable on the later of 30 days after the Business Combination Closing and 12 months from the IPO Closing, and will expire five years after the Business Combination Closing or earlier upon the liquidation of the Company, as described in the Warrant Agreement. The Forward Purchase Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by the Purchaser or its Permitted Transferees (as defined below). If the Forward Purchase Warrants are held by Persons (as defined below) other than the Purchaser or its Permitted Transferees, the Forward Purchase Warrants will have the same terms as the Public Warrants, as set forth in the Warrant Agreement.

(iv) The Company shall require the Purchaser to purchase the Forward Purchase Securities by delivering notice to the Purchaser, at least five (5) Business Days before the Business Combination Closing, specifying the number of Forward Purchase Shares and Forward Purchase Warrants the Purchaser is required to purchase, the date of the Business Combination Closing, the aggregate Forward Purchase Price and instructions for wiring the Forward Purchase Price. The closing of the sale of Forward Purchase Securities (the “Forward Closing”) shall be held on the same date and immediately prior to 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, to be held in escrow until the Forward Closing, the Forward Purchase Price for the Forward Purchase Securities by wire transfer of U.S. dollars in immediately available funds to the account specified by the Company in such notice. Immediately prior to the Forward Closing on the Forward Closing Date, (A) the Forward Purchase Price shall be released from escrow automatically and without further action by the Company or the Purchaser, and (B) upon such release, the Company shall issue the Forward Purchase Securities 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 on 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 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 book entry for the Forward Purchase Securities shall contain a notation, and each certificate (if any) evidencing the Forward Purchase Securities 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. THE SALE, PLEDGE, HYPOTHECATION, OR TRANSFER OF THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN FORWARD PURCHASE AGREEMENT BY AND AMONG THE HOLDER AND THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.”

(b) Authorization. The Purchaser has full power and authority to enter into this Agreement. 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.

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.

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 Securities 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 Securities.

The Purchaser understands that the offer and sale of the Forward Purchase Securities 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 understands that the Forward Purchase Securities are “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Forward Purchase Securities indefinitely unless they are registered with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Forward Purchase Securities, or any Class A Shares for which they may be exercised, for resale, except as provided herein (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 Securities, 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 Securities 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.

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

(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) Adequacy of Financing. At the time of the Forward Closing, the Purchaser will have available to it sufficient funds to satisfy its obligations under this Agreement.

(n) Affiliation of Certain FINRA Members. The Purchaser is neither a person associated nor affiliated with Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, Xxxxxxx, Xxxxx & Co. or, to its actual knowledge, any other member of the Financial Industry Regulatory Authority (“FINRA”) that is participating in the IPO.

(b) Indemnification.

(i) The Company shall, notwithstanding any termination of this Agreement, indemnify, defend and hold harmless the Purchaser (to the extent a seller under the Forward Registration Statement), the officers, directors, agents, partners, members, managers, stockholders, affiliates, employees and investment advisers of the Purchaser, each person who controls the Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), and the officers, directors, partners, members, managers, stockholders, agents, affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (A) any untrue or alleged untrue statement of a material fact contained in the Forward Registration Statement, any prospectus included in the Forward Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (B) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 4, except to the extent, but only to the extent that such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding the Purchaser furnished in writing to the Company by the Purchaser expressly for use therein. The Company shall notify the Purchaser promptly of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 4 of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Registrable Securities by the Company.

(ii) The Purchaser shall, severally and not jointly with any other selling stockholder named in the Forward Registration Statement, indemnify and hold harmless the Company, its directors, officers, agents and employees, each person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or that are based upon any untrue or alleged untrue statement of a material fact contained in the Forward Registration Statement, any prospectus included in the Forward Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent that such untrue statements or omissions are based solely upon information regarding the Purchaser furnished in writing to the Company by the Purchaser expressly for use therein. In no event shall the liability of the Purchaser be greater in amount than the dollar amount of the net proceeds received by the Purchaser upon the sale of the Registrable Securities giving rise to such indemnification obligation.

(c) Transfer. This Agreement and all of the Purchaser’s rights and obligations hereunder (including the Purchaser’s obligation to purchase the Forward Purchase Securities) may be transferred or assigned, at any time and from time to time, in whole or in part, to 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 “Joinder Agreement”), which shall reflect the number of Forward Purchase Shares and Forward Purchase Warrants 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 Joinder Agreement, the number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by the Purchaser hereunder shall be reduced by the total number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by the applicable Transferee pursuant to the applicable Joinder Agreement, which reduction shall be evidenced by the Purchaser and the Company amending Schedule A to this Agreement to reflect each transfer and updating the “Number of Forward Purchase Shares”, “Number of Forward Purchase Warrants”, and “Aggregate Purchase Price for Forward Purchase Securities” on the Purchaser’s signature page hereto to reflect such reduced number of Forward Purchase Securities, 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 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.

(d) Additional Transfers. The Purchaser and the Company hereby covenant and agree that, in the event that any such transfer or assignment is made pursuant to Section 4(c) above:

(i) the Purchaser shall, directly or indirectly, transfer and assign to such Transferee (the “Additional Transfers”) a proportionate number of the Sponsor Founder Shares and Private Placement Warrants (or the obligation to purchase such Private Placement Warrants), in consideration of the payment by such Transferee to the Purchaser of the original purchase price paid by the Purchaser for any such securities;

(ii) the Purchaser and/or the Company, as applicable, shall enter into appropriate documentation with such Transferee to effect the Additional Transfers and, as applicable, any new issuance of any such securities pursuant to such documentation; and

(iii) the Company shall appropriately reflect any such Additional Transfers and issuances on its books and records or direct its transfer agent to reflect any such Additional Transfers and issuances on the books and records of the Company.

5. Additional Agreements and Acknowledgements of the Purchaser.

(a) Sponsor Founder Share Lock-up; Transfer Restrictions. The Purchaser agrees that it shall not Transfer (as defined below) any Sponsor Founder Shares or any Class A Shares into which the Sponsor Founder Shares are convertible until the earlier of (i) one year after the Business Combination Closing or (ii) the date following the Business Combination Closing on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Company’s stockholders having the right to exchange their common stock for cash, securities or other property. Notwithstanding the foregoing, if, subsequent to a Business Combination, the last sale price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Business Combination Closing, the Sponsor Founder Shares (and the Class A Shares into which the Sponsor Founder Shares are convertible) shall be released from the lockup referenced herein. Notwithstanding the first sentence of this Section 5(a), Transfers of the Sponsor Founder Shares (and the Class A Shares into which the Sponsor Founder Shares are convertible) 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 a 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. For purposes of this Section, “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 Securities (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 Securities, whether any such transaction is to be settled by delivery of such Forward Purchase Securities, in cash or otherwise, or (z) public announcement of any intention to effect any transaction specified in clause (x) or (y).

(b) Warrant Lock-up; Transfer Restrictions. The Purchaser agrees that it shall not Transfer any Private Placement Warrants or any Forward Purchase Warrants (or Class A Shares issued or issuable upon the exercise of any such warrants) until 30 days after the completion of a Business Combination, except that Transfers of the Private Placement Warrants and Forward Purchase Warrants are permitted to any Permitted Transferee.

(c) Potential Forfeiture. To the extent that the IPO Option is not exercised in full, the Purchaser shall forfeit to the Company for no consideration, a number of Sponsor Founder Shares in the aggregate equal to the product of 1,500,000 multiplied by a fraction, (i) the numerator of which is 6,000,000 minus the number of Public Units purchased upon the exercise of the IPO Option, and (ii) the denominator of which is 6,000,000. The forfeiture will be adjusted to the extent that the IPO Option is not exercised in full (or the Company increases or decreases the size of the IPO) so that the holders of the Class B Shares immediately prior to the IPO will own an aggregate of 20.0% of the Company’s issued and outstanding common stock immediately after the IPO.

(d) 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.

(e) Redemption and Liquidation. The Purchaser hereby waives, with respect to any Sponsor Founder Shares (including the Class A Shares into which such Sponsor Founder Shares are convertible) held by it, any redemption rights it may have in connection with (i) the consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination and (ii) any stockholder vote to approve an amendment to the Charter to modify the substance or timing of the Company’s obligation to redeem 100% of the Class A Shares sold in the IPO if the Company has not consummated an initial Business Combination within 24 months from the IPO Closing or in the context of a tender offer made by the Company to purchase Class A Shares, it being understood that the Purchaser shall be entitled to redemption and liquidation rights with respect to any Public Shares held by it.

(f) Voting. The Purchaser hereby agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, the Purchaser shall vote any Class B Shares and Class A Shares owned by it in favor of any proposed Business Combination.

(g) No Short Sales. The Purchaser hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any understanding with it, will engage in any Short Sales with respect to securities of the Company prior to the Business Combination Closing. For purposes of this Section, “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign regulated brokers.

(vi) 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

(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 litigation 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. The parties (i) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of New York and to the jurisdiction of the United States District Court for the Southern District of New York for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (ii) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in state courts of New York or the United States District Court for the Southern District of New York, and (iii) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

(k) Waiver of Jury Trial. 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.

(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. Each of the Company and the Purchaser will bear its own costs and expenses incurred in connection with the preparation, execution and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of agents, representatives, financial advisors, legal counsel and accountants.

(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.
