3.            Method of Exercise.

3.1            Cash Exercise. Prior to the receipt of Stockholder Approval (as defined in Section 17), the right to purchase Shares under this Warrant shall not be exercisable. Following the receipt of Stockholder Approval, the right to purchase Shares under this Warrant shall be exercised by the Holder, in whole or in part, by the surrender of this Warrant (with the notice of exercise form attached hereto as Exhibit A duly executed (the “Exercise Notice”)) at the principal office of the Company, and by the payment to the Company, by certified, cashier’s or other check acceptable to the Company or by wire transfer to an account designated by the Company, of an amount equal to the aggregate Exercise Price for the Shares being purchased. A cash exercise, shall not be effective unless and until the Company has received payment in full of the aggregate Exercise Price for the Shares being purchased; if such payment is not received, any purported notice of exercise shall be deemed void and of no force or effect.

3.2            Net Issue Exercise. In lieu of exercising this Warrant, the Holder may elect to receive Shares equal to the value of this Warrant (or the portion thereof being canceled) by surrender of this Warrant at the principal office of the Company together with notice of such election, in which event the Company shall issue to the Holder a number of Shares computed using the following formula:

Where: X = the number of the Shares to be issued to the Holder.

Y = the number of the Shares purchasable under this Warrant.

A = the fair market value of one Share on the date of determination.

B = the per share Exercise Price (as adjusted to the date of such calculation).

3.3            Automatic Cashless Exercise. To the extent that there has not been an exercise by the Holder pursuant to Section 3.1 hereof, any portion of the Warrant that remains exercisable but unexercised shall be exercised automatically upon the Expiration Date (including upon a Liquidation Event) pursuant to the mechanics described in Section 3.2.

3.4            Fair Market Value. For purposes of Section 3.2 hereof, the per share fair market value of the Shares shall mean: (i) if the Common Stock remains publicly traded, the per share fair market value of the Shares shall be the average of the closing prices of the Common Stock on the principal exchange on which the Common Stock is listed (i.e. the New York Stock Exchange (“NYSE”)) or if the Common Stock is not so listed, as quoted on the Over-the-Counter Bulletin Board, in each case for the fifteen trading days ending five trading days prior to the date of determination of fair market value; (ii) if the Common Stock is not so publicly traded, the per share fair market value of the Shares shall be such fair market value as is determined jointly by the Board (acting in good faith) and the Holder; provided, that if the Board and the Holder are unable to agree on the fair market value per share of the Common Stock within a reasonable period of time (not to exceed fifteen days from the Company's receipt of the Exercise Notice), such fair market value shall be determined by a nationally recognized investment banking, accounting, or valuation firm jointly selected by the Board and the Holder acting in good faith. The determination of such firm shall be final and conclusive, and the fees and expenses of such valuation firm shall be borne by the Company. In determining per share fair market value of the Shares in accordance with the foregoing clause (ii), an orderly sale transaction between a willing buyer and a willing seller shall be assumed, using valuation techniques then prevailing in the securities industry without regard to the lack of liquidity of the Shares due to any restrictions (contractual or otherwise) applicable thereto or any discount for minority interests and assuming full disclosure of all relevant information and a reasonable period of time for effectuating such sale and assuming the sale of all of the issued and outstanding Shares (including fractional interests) calculated on a fully diluted basis to include the conversion or exchange of all securities then outstanding that are convertible into or exchangeable for Shares and the exercise of all rights and warrants then outstanding and exercisable to purchase shares of Common Stock or securities convertible into or exchangeable for shares of Common Stock; provided, that such assumption shall not include those securities, rights, and warrants (a) owned or held by or for the account of the Company or any of its subsidiaries, or (b) convertible or exchangeable into Common Stock where the conversion, exchange, or exercise price per share is greater than the per share Fair Market Value of the Shares.

4.            Treatment of Warrant Upon a Liquidation Event. Without limitation to Holder’s right to elect, in its sole discretion, to exercise (including net issue exercise) the Warrant at any time during the Exercise Period and without limitation to any other provision contained herein, in the event of a Liquidation Event, either (a) Holder shall affirmatively exercise this Warrant in full with respect to all remaining Shares for which the Warrant is then exercisable and such exercise will be deemed effective immediately prior to the consummation of such Liquidation Event or (b) if Holder affirmatively elects not to exercise the Warrant, this Warrant will expire upon the consummation of such Liquidation Event; provided, however, should Holder not affirmatively elect option (a) or (b), then the Warrant will automatically convert in full with respect to all remaining Shares for which the Warrant is then exercisable and such conversion will be deemed effective immediately prior to the consummation of such Liquidation Event with payment owed on the full exercise price on a cashless basis pursuant to Section 3.2 hereof. The Company shall provide Holder with written notice of the foregoing (together with such information as Holder may reasonably request in connection with such contemplated Liquidation Event giving rise to such notice), which is to be delivered to Holder not less than ten (10) days prior to the closing or occurrence, as applicable, of the proposed Liquidation Event. For the avoidance of doubt, the occurrence of a Liquidation Event is not required for the Holder to exercise this Warrant.

5.            Certificates for Shares. As soon as practicable upon the exercise of this Warrant (and in any event within three (3) business days), the Company shall issue the Holder (i) a certificate (or book-entry entitlement) for the number of Shares so purchased and, (ii) if such exercise is in part, a new warrant (dated the date hereof) of like tenor representing the remaining number of Shares purchasable under this Warrant. Holder shall be deemed to own and have all of the rights associated with any Shares or other securities or property to which it is entitled pursuant to this Warrant upon the exercise of the Warrant in accordance with Section 3 hereof.

6.            Replacement of Warrants. On receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant and in the case of loss, theft or destruction, on delivery of an indemnity agreement reasonably satisfactory in form and amount to the Company or, in the case of mutilation on surrender and cancellation of this Warrant, the Company shall promptly execute and deliver, in lieu of this Warrant, a new warrant of like tenor.

7.            Issuance of Shares. The Company covenants that the Shares, when issued pursuant to the exercise of this Warrant, will be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges with respect to the issuance thereof.

8.            Adjustment of Exercise Price and Number of Shares. The number of and kind of securities purchasable upon exercise of this Warrant and the Exercise Price shall be subject to adjustment from time to time as follows:

8.1            Merger, Consolidation or Sale of Assets. If at any time there shall be a merger or a consolidation of the Company with or into another entity when the Company is not the surviving entity, or a sale of all or substantially all of the assets of the Company in one or a series of related transactions, then, as part of such merger, consolidation, sale of assets or similar transaction, lawful provision shall be made so that the Holder shall thereafter be entitled to receive upon exercise of this Warrant, during the period specified herein and upon payment of the aggregate Exercise Price then in effect, the number of shares of stock or other securities or property (including cash) of the successor entity resulting from such merger, consolidation, sale or similar transaction, to which the Holder as the holder of Shares deliverable upon exercise of this Warrant would have been entitled in such merger, consolidation, sale or similar transaction, if this Warrant had been exercised immediately before such merger, consolidation, sale or similar transaction. In any such case, appropriate adjustment shall be made in the application of the provisions of this Warrant with respect to the rights and interests of the Holder after the merger, consolidation, sale or similar transaction. This provision shall apply to successive mergers or consolidations.

8.2            Reclassification, Recapitalization, etc. Upon any reclassification, exchange, substitution, or other event that results in a change of the number and/or class of the securities issuable upon exercise of this Warrant (other than a Liquidation Event which is subject to the provisions of Section 4), Holder shall be entitled to receive, upon exercise of this Warrant the number and kind of securities and property that Holder would have received for the Shares if this Warrant had been exercised immediately before such reclassification, exchange, substitution or other event. The Company or its successor shall promptly issue to Holder an amendment to this Warrant setting forth the number and kind of such new securities or other property issuable upon exercise of this Warrant as a result of such reclassification, exchange, substitution or other event that results in a change of the number and/or class of securities issuable upon exercise of this Warrant. The amendment to this Warrant shall provide for adjustments which shall be as nearly equivalent as may be practicable to the adjustments provided for in this Section 8 including, without limitation, adjustments to the Exercise Price and to the number of securities or property issuable upon exercise of the new Warrant. The provisions of this Section 8 shall similarly apply to successive reclassifications, exchanges, substitutions or other events.

8.3            Split, Subdivision or Combination of Shares. If the Company, at any time while this Warrant remains outstanding and unexpired, shall split, subdivide or combine the securities as to which purchase rights under this Warrant exist, the Exercise Price shall be proportionately decreased in the case of a split or subdivision or proportionately increased in the case of a combination.

8.4            Common Stock Dividends. If the Company, at any time while this Warrant is outstanding and unexpired, pays a dividend with respect to Common Stock payable in Shares, or makes any other distribution with respect to Common Stock payable in Shares, then the Exercise Price shall be adjusted, from and after the date of determination of the stockholders entitled to receive such dividend or distribution, to that price determined by multiplying the Exercise Price in effect immediately prior to such date of determination by a fraction (i) the numerator of which shall be the total number of shares of Common Stock outstanding immediately prior to such dividend or distribution, and (ii) the denominator of which shall be the total number of shares of Common Stock outstanding immediately after such dividend or distribution.

8.5            Other Dividends. In case the Company, at any time, pays a dividend or makes a distribution on its Common Stock (other than a dividend or distribution in Shares), the Holder shall receive the cash, other securities or property which the Holder would have been entitled to receive if the Holder had exercised this Warrant immediately prior to the record date for the determination of stockholders entitled to receive such dividend or distribution. The amount of any such other securities and property which the Holder shall thereafter be entitled to receive upon the exercise of this Warrant shall be subject to adjustment from time to time, in a manner and on terms as nearly equivalent as practicable to those contained herein with respect to the Common Stock of the Company. The provisions of this Section 8.7 shall similarly apply to successive dividends or distributions of the character specified above.

8.6            Adjustment of Number of Shares. Whenever an adjustment is made in the Exercise Price pursuant to any of Sections 8.1 through 8.5 hereof, the total number of Shares acquired upon exercise of this Warrant shall also be adjusted, to the nearest whole share of Common Stock, to the product obtained by multiplying the number of Shares purchasable immediately prior to such adjustment in the Exercise Price by a fraction (i) the numerator of which shall be the Exercise Price immediately prior to such adjustment, and (ii) the denominator of which shall be the Exercise Price immediately after such adjustment.

8.7            Other Adjustment Events. If any event occurs of the type contemplated by the provisions of this Section 8 but not expressly provided for by such provisions, then the Board will make an appropriate adjustment in the Exercise Price and the number of Shares so as to achieve the intended result of the Warrant; provided, that no such adjustment pursuant to this Section 8.7 will increase the Exercise Price or decrease the number of Shares as otherwise determined pursuant to this Section 8.

8.8            Notice of Adjustments; Other Notices. Whenever the Exercise Price or number or type of securities issuable hereunder shall be adjusted pursuant to any provision of this Section 8, the Company shall issue and provide to the Holder, subject to the following sentence, prior written notice setting forth, in reasonable detail, the event requiring the adjustment, the amount of the adjustment, the method by which such adjustment was calculated and the Exercise Price and number of Shares purchasable hereunder after giving effect to such adjustment. In addition, so long as this Warrant shall be outstanding, (i) if the Company shall declare any dividend or make any distribution upon the Common Stock or (ii) if any capital reorganization of the Company, reclassification of the capital stock of the Company, consolidation or merger of the Company with or into another entity, sale, lease or transfer of all or substantially all of the property and assets of the Company, or voluntary or involuntary dissolution, liquidation or winding up of the Company shall be effected, where such aforementioned events are not within the Liquidation Event, then in each such case, the Company shall cause to be mailed to the Holder, at least fifteen (15) days prior to the date specified in (x) or (y) below, as the case may be, a notice containing a brief description of the proposed action and stating the date on which (x) a record is to be taken for the purpose of such dividend or distribution, or (y) such reclassification, reorganization, consolidation, merger, conveyance, lease, dissolution, liquidation or winding up is to take place and the date, if any is to be fixed, as of which the holders of Common Stock or other securities shall receive cash or other property deliverable upon such reclassification, reorganization, consolidation, merger, conveyance, dissolution, liquidation or winding up.

9.            Reservation of Stock. The Company agrees during the term the rights under this Warrant are exercisable to reserve and keep available from its authorized and unissued shares of Common Stock for the purpose of effecting the delivery upon exercise of this Warrant such number of validly issued, fully paid and nonassessable Shares as shall from time to time be deliverable upon the exercise of this Warrant.

10.            No Fractional Shares or Scrip. No fractional shares or scrip representing fractional Shares shall be issued upon the exercise of this Warrant, but in lieu of such fractional Shares the Company shall make a cash payment therefor on the basis of the Exercise Price then in effect.

11.            Representations and Warranties of the Company. The Company represents and warrants to the Holder as follows:

11.1            the execution, delivery and performance of this Warrant and the Registration Rights Agreement and the consummation of the transactions contemplated hereby (other than the Stockholder Approval contemplated by Section 17 that has not been obtained as of the date hereof) have been duly and validly authorized by all necessary corporate action on the part of the Company and its stockholders, and no consent of any other person is required to be obtained as a prerequisite to the validity, enforceability and full performance of this Warrant and the transactions contemplated hereby. The Company has, at any time, the full legal right, power and authority to execute and deliver this Warrant and the Registration Rights Agreement and to perform its obligations hereunder and thereunder.

11.2            all Shares that may be issued upon the exercise of this Warrant shall, upon issuance, be duly authorized, validly issued, fully paid and non-assessable, and free of any liens and encumbrances except for restrictions on transfer provided for herein or applicable federal and state securities laws. The Company covenants that it shall reserve and keep available out of its authorized and unissued capital stock such number of shares of Common Stock and other securities as will be sufficient to permit the exercise in full of this Warrant.

11.3            the Company is not a party to or otherwise subject to any contract or agreement that restricts or otherwise affects its right to execute and deliver this Warrant and the Registration Rights Agreement or to perform its obligations hereunder and thereunder (including the issuance of Shares), except where all necessary consents or waivers have been obtained. Neither the execution, delivery nor performance of this Warrant (including the issuance of Shares) will (i) conflict with, result in a breach of the terms, conditions or provisions of, (ii) constitute a default under, result in any violation of, result in the creation of any lien upon any properties of the Company under, or (iii) require any consent, approval or other action by or notice to or filing with any court or governmental body pursuant to the Company’s certificate of incorporation or bylaws relating to, any award of any arbitrator or any agreement, instrument or law to which the Company is subject or by which it is bound.

11.4            subject to Section 17, 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 Company in connection with the consummation of the transactions contemplated by this Warrant, except for such filings described herein pursuant to applicable securities laws, which have been made or will be made in a timely manner.

11.5            the execution, delivery and performance of this Warrant and the Registration Rights Agreement and the consummation of the transactions contemplated by this Warrant and the Registration Rights Agreement will not result in any such violation or be in conflict with or constitute, with or without the passage of time and giving of notice, either (i) a default under any such provision, instrument, judgment, order, writ, decree, contract or agreement; or (ii) an event which results in the creation of any lien, charge or encumbrance upon any assets of the Company or the suspension, revocation, forfeiture, or nonrenewal of any material permit or license applicable to the Company.

11.6            the Company shall take all such actions as may be necessary to ensure that all such Shares are issued without violation by the Company of any applicable law or governmental regulation or any requirements of the NYSE or any domestic securities exchange upon which shares of Common Stock or other securities constituting the Shares may be listed at the time of such exercise.

12.            Representations and Warranties by the Holder. The Holder represents and warrants to the Company as follows:

12.1            Own Account. This Warrant and the Shares issuable upon exercise hereof are being acquired for its own account, for investment and not with a view to the public resale or distribution within the meaning of the Securities Act and the Holder has no present intention, and upon exercise will have no intention, of selling or engaging in any public distribution of the same except pursuant to a registration or exemption. Holder also represents that the Holder has not been formed for the specific purpose of acquiring this Warrant or the Shares.

12.2            Disclosure of Information. The Holder has received or has had full access to all the information it considers necessary or appropriate to make an informed investment decision with respect to the acquisition of this Warrant and the Shares. The Holder further has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of this Warrant and the Shares and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to verify any information furnished to the Holder or to which the Holder has access. Notwithstanding the foregoing, the Company shall provide written notice to the Holder reasonably in advance of the occurrence of any Liquidation Events; provided, that such notice shall be treated as Confidential Information of the Company and may not be disclosed by Holder except to its legal and financial advisors who agree to maintain the confidentiality of such information.

12.3            Investment Experience. The Holder understands that the exercise of this Warrant and the purchase of the Shares involve substantial risk. The Holder acknowledges that the Holder can bear the economic risk of such Holder’s investment in this Warrant and the Shares and has such knowledge and experience in financial or business matters that the Holder is capable of evaluating the merits and risks of its investment in this Warrant and the Shares and/or has a preexisting personal or business relationship with the Company and certain of its officers, directors or controlling persons of a nature and duration that enables the Holder to be aware of the character, business acumen and financial circumstances of such persons.

12.4            Accredited Investor Status. The Holder is an “accredited investor” within the meaning of Regulation D promulgated under the Securities Act.

12.5            The Securities Act. The Holder understands that this Warrant and the Shares issuable upon exercise hereof have not been registered under the Securities Act in reliance upon a specific exemption therefrom, which exemption depends upon, among other things, the bona fide nature of the Holder’s investment intent as expressed herein. The Holder understands that this Warrant and the Shares issued upon any exercise hereof must be held indefinitely unless subsequently registered under the Securities Act and qualified under applicable state securities laws, or unless exemptions from such registration and qualification are otherwise available. The Holder further understands that settlement of this Warrant is to be made in Shares and, for the elimination of doubt, the fact that the Shares delivered on exercise of this Warrant will not be registered under the Securities Act will not in any way require the Company to settle this Warrant otherwise than in Shares.

13.            Rule 144 Compliance; Legend Removal.

13.1            If the Holder proposes to sell the Shares issuable upon the exercise of this Warrant in compliance with Rule 144 promulgated by the Securities and Exchange Commission (the “SEC”), then, upon the Holder’s reasonable request to the Company, the Company shall use commercially reasonable efforts to assist with the transaction, including furnishing to the Holder, to the extent accurate, a written statement confirming the Company’s compliance with the filing requirements of the SEC as set forth in such Rule 144, as may be amended from time to time.

13.2            Subject to receipt from the Holder by the Company of customary representations and other documentation reasonably acceptable to the Company and the Company’s transfer agent in connection therewith, and upon the Holder’s reasonable request, the Company shall use commercially reasonable efforts to remove any legend from the book entry position or certificate evidencing such Holder’s Shares and the Company will, as soon as practicable, if required by the Company’s transfer agent, cause an opinion of the Company’s counsel to be provided, in a form reasonably acceptable to the Company’s transfer agent, to the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act following the earliest of such time as: (i) such Shares have been sold pursuant to Rule 144 or (ii) such Shares are eligible for resale under Rule 144(b)(1) or any successor provision without the requirement for the Company to be in compliance with the current public information requirement under Rule 144 and without volume or manner-of-sale restrictions applicable to the sale or transfer of such Shares.

14.            Legends. This Warrant and the Shares (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) shall be imprinted with a legend in substantially the following form:

15.            Warrants Transferability. At any time and from time to time prior to the Expiration Date, the Holder may, pursuant to this Section 15, Section 16 and subject to the transfer restrictions set forth in the Registration Rights Agreement, sell, assign or transfer this Warrant and the Warrant Shares in whole or in part to (i) any Affiliate of the Holder, or (ii) any person that is not an Affiliate of the Holder (each such person, a “Third Party Transferee”) that is acquiring Warrants representing at least one-sixth (1/6^th) of the total Warrant Shares issuable upon exercise of this Warrant as of the original issuance date in such transfer; provided, that (A) no Third Party Transferee shall be, or shall be an Affiliate of, a developer, designer or manufacturer of vertical take-off and landing aircraft (a “VTOL OEM”), (B) any portion of this Warrant shall not be transferred more than three (3) times without the Company’s prior written consent, which such consent shall not be unreasonably withheld, (C) any such transfer shall be subject to compliance with applicable securities laws and the requirement that such transferee agrees in writing to be bound by the terms of this Warrant and the Registration Rights Agreement (including, for the avoidance of doubt, the transfer restrictions applicable to Third Party Transferees set forth in clauses (A) and (B) above), and (D) Holder shall give the Company written notice of any such transfer, identifying the transferee and the number of Warrants being transferred, promptly following the consummation of such transfer. The Company agrees that it shall use commercially reasonable efforts to promptly assist the Holder in making any such transfer in compliance with any applicable federal and state securities laws, including, without limitation, taking the actions described in Section 13 mutatis mutandis as such actions apply to the Warrant; provided, that in any such transfer, the transferee shall agree to be bound by the terms of this Warrant as if an original holder hereof.

16.            Compliance with Securities Laws on Transfer. This Warrant and the Shares issuable upon exercise of this Warrant (and the securities issuable, directly or indirectly, upon conversion of the Shares, if any) may not be transferred or assigned in whole or in part without compliance with applicable federal and state securities laws by the transferor and the transferee (including, without limitation, the delivery of investment representation letters and legal opinions reasonably satisfactory to the Company, as reasonably requested by the Company). The Company shall not require Holder to provide an opinion of counsel if the transfer is to any Affiliate of the Holder; provided, that any such transferee is an “accredited investor” as defined in Regulation D promulgated under the Securities Act.

17.            Compliance with NYSE Listing Rule Requirements; Beneficial Ownership Cap; Regulatory Approvals. Notwithstanding anything to the contrary in this Warrant:

17.1            Beneficial Ownership Cap. Unless the Holder has expressly waived the restrictions set forth in this this Section 17.1, the Company shall not issue, and the Holder shall not be entitled to receive, any Shares under this Warrant to the extent that, after giving effect to such issuance and exercise, the Holder (together with its Affiliates and any other persons whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act or applicable stock exchange rules) would (i) beneficially own a number of shares of Common Stock equal to or exceeding 19.9% of the then-issued and outstanding shares of Common Stock, or (ii) be entitled to vote or direct the voting of a number of shares equal to or exceeding 19.9% of the combined voting power of all then-issued and outstanding securities of the Company entitled to vote generally in the election of directors. Unless the Holder has expressly waived the restrictions set forth in this this Section 17.1, any purported exercise of this Warrant in violation of this Section 17.1 shall be null and void to the extent of such excess.

17.2            Stockholder Approval. As used in this Warrant, “Stockholder Approval” means the approval of the Company’s stockholders under Section 312.03 of the NYSE Listed Company Manual to permit the issuance of Shares upon exercise of this Warrant, if and when such approval is obtained. The Company shall seek Stockholder Approval pursuant to the terms and conditions set forth in the Side Letter until such Stockholder Approval is obtained.

17.3            Regulatory Approvals. The right to purchase Shares under this Warrant shall not be exercisable, and the Company shall not issue any Shares upon exercise of this Warrant, unless and until: (a) all filings, notifications, clearances, approvals, consents, or authorizations required under any applicable Antitrust Laws (as defined in the Purchase Agreement) shall have been made, obtained, deemed approved, or waived, as applicable, in each case with respect to the issuance of Shares upon exercise of this Warrant (the “Warrant Regulatory Approvals”); and (b) no Governmental Order (as defined in the Purchase Agreement) shall have been adopted, promulgated, or entered by any Governmental Authority that is in effect and that prohibits or restrains the issuance of Shares upon exercise of this Warrant. For the avoidance of doubt, the conditions set forth in this Section 17.3 shall apply in addition to, and not in lieu of, the Stockholder Approval requirement and the limitations on beneficial ownership set forth in Sections 17.1 and 17.2, respectively.

17.4            Regulatory Approval Efforts. In connection with the exercise or anticipated exercise of this Warrant, each of the Company and the Holder shall (a) as promptly as practicable following the delivery of any Exercise Notice, or at such earlier time as either party determines that Warrant Regulatory Approvals may be required, make all filings, notifications, and submissions required to be made under any applicable Antitrust Laws in connection with the issuance of Shares upon exercise of this Warrant and (b) use reasonable best efforts to obtain the Warrant Regulatory Approvals as promptly as practicable, in each case in accordance with, and subject to the terms and conditions set forth in, Section 6.6 of the Purchase Agreement.

18.            Notices. All notices hereunder shall be effective when given, and shall be deemed to be given upon receipt or, if earlier, (a) five (5) days after deposit with the U.S. Postal Service or other applicable postal service, if delivered by first class mail, postage prepaid, (b) upon delivery, if delivered by hand, (c) one business day after the business day of deposit with Federal Express or similar overnight courier, freight prepaid or (d) one business day after email transmission, and shall be addressed at such address as the Holder or the Company (as applicable) shall have furnished in writing.

Tasman Drive, San Jose, CA 95134, Attention: General Counsel, email: [***], with a copy to the Company’s counsel at Fenwick & West LLP, 801 California Street, Mountain View, CA 94041, Attention: Patrick Grilli, email: [***].

19.            Governing Law, Jurisdiction, Waiver of Jury Trial. This Warrant shall be governed by, and construed in accordance with, the laws of the State of Delaware applicable to contracts executed in and to be performed in that State. All legal actions and proceedings arising out of or relating to this Warrant shall be heard and determined exclusively in any Delaware Chancery Court; provided, that if jurisdiction is not then available in the Delaware Chancery Court, then any such legal action may be brought in any federal court located in the State of Delaware or any other Delaware state court. The parties hereto hereby (a) irrevocably submit to the exclusive jurisdiction of the aforesaid courts for themselves and with respect to their respective properties for the purpose of any action arising out of or relating to this Warrant brought by any party hereto, and (b) agree not to commence any action relating thereto except in the courts described above in Delaware, other than actions in any court of competent jurisdiction to enforce any judgment, decree or award rendered by any such court in Delaware as described herein. Each of the parties further agrees that notice as provided herein shall constitute sufficient service of process and the parties further waive any argument that such service is insufficient. Each of the parties hereby irrevocably and unconditionally waives, and agrees not to assert, by way of motion or as a defense, counterclaim or otherwise, in any action arising from this Warrant or the Shares, (a) any claim that it is not personally subject to the jurisdiction of the courts in Delaware as described herein for any reason, (b) that it or its property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment or otherwise) and (c) that (i) the action in any such court is brought in an inconvenient forum, (ii) the venue of such action is improper or (iii) this Warrant, or the subject matter hereof, may not be enforced in or by such courts. ANY RIGHT TO TRIAL BY JURY WITH RESPECT TO ANY CLAIM OR ACTION ARISING OUT OF THIS WARRANT IS HEREBY WAIVED.

20.            Equitable Relief. Each of the Company and the Holder acknowledges that a breach or threatened breach by such party of any of its obligations under this Warrant would give rise to irreparable harm to the other party hereto for which monetary damages would not be an adequate remedy and hereby agrees that in the event of a breach or a threatened breach by such party of any such obligations, the other party hereto shall, in addition to any and all other rights and remedies that may be available to it in respect of such breach, be entitled to equitable relief, including a temporary restraining order, an injunction, specific performance, and any other relief that may be available from a court of competent jurisdiction without having to prove the inadequacy of money damages.

21.            Cumulative Remedies. All rights and remedies of each party under this Warrant and under the Side Letter are cumulative and in addition to, and not in lieu of, any other rights and remedies available to such party at law, in equity, by contract, or otherwise.

22.            Amendments and Waivers. No modification of or amendment to this Warrant will be effective unless in a writing signed by all of the parties hereto. No waiver by the Company or the Holder of any of the provisions hereof shall be effective unless explicitly set forth in writing and signed by the party so waiving. Waiver by the Holder of a breach of any provision of this Warrant will not operate as a waiver of any other or subsequent breach.

23.            No Impairment. The Company shall not, by amendment of its Certificate of Incorporation or through a reorganization, transfer of assets, consolidation, merger, dissolution, issue, or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed under this Warrant by the Company, but shall at all times in good faith assist in carrying out of all the provisions of this Warrant and in taking all such action as may be necessary or appropriate to protect the Holder’s rights under this Warrant against impairment.

24.            Counterparts. The Warrant may be executed in one or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. Pdf copies of signature pages shall be binding originals.
