Exhibit 4.2

WARRANT AGREEMENT

THIS WARRANT AGREEMENT (this “Agreement”), dated as of May 15, 2023, is entered into by and between NextNav Inc., a Delaware corporation (the “Company”), and Continental Stock Transfer & Trust Company, a New York corporation (the “Warrant Agent”). Certain terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Warrants (defined below).

WHEREAS, the Company has issued warrants to purchase shares of common stock, par value $0.0001 (“Common Stock”) of the Company (the “Warrants”) to certain purchasers;

WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of the Warran ts;

WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the holders of the Warrants; and

WHEREAS, all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.

NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows:

1.Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement.

2.Warrants.

2.1Form of Warrant. Each Warrant shall be issued in registered form only, and, if a physical certificate is issued, shall be in substantially the form agreed to between the Company and the Warrant Agent, the provisions of which are incorporated herein, and signed by, or bear the facsimile signature of, the Chairman of the Board, the President, Chief Executive Officer, Chief Financial Offer, Secretary or other principal officer of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. To the extent any provisions of this Agreement conflict with the provisions of the Warrant, the provisions of the Warrant shall prevail.

2.2Effect of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant certificate shall be invalid and of no effect and may not be exercised by the holder thereof.

2.3Registration.

2.3.1Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of the original issuance and transfers of the Warrants. Upon the initial issuance of the Warrants, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. The Warrants shall initially be represented by one or more book-entry certificates deposited with the Warrant Agent. As soon as practicable after execution of this Agreement, the Warrants shall be represented by one or more book-entry certificates (each, a “Book-Entry Warrant Certificate”) deposited with The Depository Trust Company (the “Depositary”) and registered in the name of Cede & Co., a nominee of the Depositary. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained by (i) the Depositary or its nominee for each Book-Entry Warrant Certificate, or (ii) institutions that have accounts with the Depositary (each such institution, with respect to a Warrant in its account, a “Participant”). For the avoidance of doubt, until such time as the Warrants are deposited with the Depositary, the Warrants shall be represented by one or more book-entry certificates deposited with the Warrant Agent.

If the Depositary subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for the book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical form evidencing such Warrants (“Definitive Warrant Certificate”). Such Definitive Warrant Certificate shall be in a form agreed to between the Company and the Warrant Agent.

2.3.2Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (the “registered holder”), as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on a Definitive Warrant Certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

3.Terms and Exercise of Warrants.

3.1Warrant Price. Each Warrant shall entitle the registered holder thereof, subject to the provisions of such Warrant, as the case may be, and of this Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $ per whole share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement refers to the price per share at which Common Stock may be purchased at the time a Warrant is exercised. The Company, in its sole discretion, may lower the Warrant Price at any time prior to the Expiration Date (as defined below).

3.2Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on or after July 8, 2023 and terminating at 5:00 p.m., New York City time on the earlier to occur of (x) July 1, 2027 or (y) the date fixed for redemption of the Warrants as provided in Section 6 of this Agreement (the “Expiration Date”). Except with respect to the right to receive the Redemption Price (as set forth in Section 6 hereunder), each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at the close of business on the Expiration Date. The Company, in its sole discretion, may extend the duration of the Warrants by delaying the Expiration Date.

3.3Exercise of Warrants.

3.3.1 Payment. Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the registered holder thereof by delivering to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Book-Entry Warrant Certificate, the Warrants to be exercised on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purpose in writing by the Warrant Agent to the Depositary from time to time, (ii) an election to purchase (“Election to Purchase”) shares of Common Stock pursuant to the exercise of a Warrant, properly completed and executed by the registered holder on the reverse of the Definitive Warrant Certificate or, in the case of a Book-Entry Warrant Certificate, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii) payment in full of the Warrant Price for each full share of Common Stock as to which the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock and the issuance of such shares of Common Stock, by certified check payable to the order of the Warrant Agent or by wire transfer.

3.3.2 Issuance of Shares of Common Stock on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price or upon surrender of the Warrant (or portion thereof) as set forth in Section 3.3.1(b), the Company shall issue to the registered holder of such Warrant a book-entry position or certificate or certificates, as applicable, representing the number of full shares of Common Stock to which he, she or it is entitled, registered in such name or names as may be directed by him, her or it, and, if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for the number of shares of Common Stock as to which such Warrant shall not have been exercised. If fewer than all the Warrants evidenced by a Book-Entry Warrant Certificate are exercised, a notation shall be made to the records maintained by the Warrant Agent, the Depositary, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise. Notwithstanding the foregoing, the Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant unless (a) a registration statement under the Act with respect to the Common Stock issuable upon exercise of such Warrants is effective and a current prospectus relating to the shares of Common Stock issuable upon exercise of the Warrants is available for delivery to the Warrant holders or (b) in the opinion of counsel to the Company, the exercise of the Warrants is exempt from the registration requirements of the Act and such securities are qualified for sale or exempt from qualification under applicable securities laws of the states or other jurisdictions in which the registered holder resides. Warrants may not be exercised by, or securities issued to, any registered holder in any state in which such exercise or issuance would be unlawful. In the event that a registration statement under the Act with respect to the Common Stock underlying the Warrants is not effective or a current prospectus is not available, or because such exercise would be unlawful with respect to a registered holder in any state, the registered holder shall not be entitled to exercise such Warrants and such Warrants may have no value and expire worthless. In no event will the Company be required to “net cash settle” the warrant exercise.

3.3.1Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

3.3.2Date of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares of Common Stock on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company or book-entry system of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of business on the next succeeding date on which the stock transfer books or book-entry system are open.

4.Adjustments.

4.1Stock Dividends - Split-Ups. If, after the date hereof, and subject to the provisions of Section 4.6 below, the number of outstanding shares of Common Stock is increased by a stock dividend payable in shares of Common Stock, or by a split-up of shares of Common Stock, or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to such increase in outstanding shares of Common Stock.

4.2Aggregation of Shares. If, after the date hereof, and subject to the provisions of Section 4.6, the number of outstanding shares of Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in proportion to such decrease in outstanding shares of Common Stock.

4.3Adjustments in Exercise Price. Whenever the number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in Sections 4.1 and 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

4.4Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change covered by Section 4.1 or 4.2 hereof or one that solely affects the par value of such shares of Common Stock), or, in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or reorganization of the outstanding shares of Common Stock), or, in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety, in connection with which the Company is dissolved, the Warrant holders shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the Warrant holder would have received if such Warrant holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any reclassification also results in a change in shares of Common Stock covered by Section 4.1 or 4.2, then such adjustment shall be made pursuant to Sections 4.1, 4.2, 4.3 and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers.

4.5Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of shares of Common Stock issuable upon exercise of a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the number of shares of Common Stock purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, then, in any such event, the Company shall give written notice to each Warrant holder, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the legality or validity of such event.

4.6No Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional shares of Common Stock upon exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round up or down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder.

4.7Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant Price and the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this Agreement. However, the Company may, at any time, in its sole discretion, make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the form as so changed.

5.Transfer and Exchange of Warrants.

5.1Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant in the Warrant Register, upon surrender of such Warrant for transfer, in the case of a certificated Warrant, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled may be delivered by the Warrant Agent to the Company from time to time upon request.

5.2Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the registered holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except as otherwise provided herein or in any Book-Entry Warrant Certificate or Definitive Warrant Certificate, each Book-Entry Warrant Certificate and Definitive Warrant Certificate may be transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor depositary, or to a nominee of a successor depositary, provided further, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer is exempt from registration under the Act and indicating whether the new Warrants must also bear a restrictive legend.

5.3Fractional Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which will result in the issuance of a warrant certificate or book-entry position for a fraction of a warrant.

5.4Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.

5.5Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose.

6.Redemption.

6.1Redemption. As provided in the Warrants, the Company shall have the right to redeem (an “Optional Redemption”) for cash the applicable Pro Rata Portion of each Warrant on each of May 1, 2025 (the “First Redemption Date”), September 1, 2025 (the “Second Redemption Date”) and December 1, 2025 (the “Third Redemption Date” and each of the foregoing, a “Redemption Date”), in each case, at a redemption price of $0.01 per share of underlying Common Stock comprising such applicable Pro Rata Portion (the “Redemption Price”) if, on the applicable Redemption Trigger Date, (i) a Funding Shortfall exists and (ii) the average of the VWAP prices for each of the thirty (30) consecutive Trading Days ending on and including the Trading Day immediately preceding such Redemption Trigger Date equals or exceeds 130% of the then-applicable Exercise Price. The “Redemption Trigger Date” applicable to the First Redemption Date is April 1, 2025; the Second Redemption Date is August 1, 2025; and the Third Redemption Date is November 1, 2025.

6.2Notice of Optional Redemption. In the event the Company exercises its Optional Redemption right to redeem the applicable Pro Rata Portion of the Warrants, it shall deliver or cause to be delivered by email to each registered holder at its last email or other address as it shall appear upon the Warrant Register a notice of such Optional Redemption (a “Redemption Notice”) in the form prescribed by the Warrant not more than five (5) days after the applicable Redemption Trigger Date. Notwithstanding the delivery of any Redemption Notice, such registered holder shall continue to have the right to exercise any portion the Warrant in accordance with its terms. If and to the extent that the registered holder exercises the Warrant after delivery of a Redemption Notice and prior to the close of business on the Trading Day immediately preceding the applicable Redemption Date, the appliable Pro Rata Portion of the Warrant redeemable by the Company pursuant to such Redemption Notice shall be reduced by the portion of this Warrant so exercised by the registered holder.

6.3Optional Redemption Limitations. With respect to each Redemption Date, the aggregate number of shares of unexercised underlying Common Stock redeemable by the Company under the Warrants outstanding on the corresponding Redemption Trigger Date pursuant to an Optional Redemption, if any, shall equal the applicable Warrant Value divided by the Exercise Price (the “Redeemable Portion”).

7.Other Provisions Relating to Rights of Holders of Warrants.

7.1No Rights as Stockholder. A Warrant does not entitle the registered holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as stockholders in respect of the meetings of stockholders or the election of directors of the Company or any other matter.

7.2Lost, Stolen, Mutilated, or Destroyed Warrants. If a physical certificate representing any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor and date as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant shall be at any time enforceable by anyone.

7.3Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

7.4Registration of Common Stock. The Company agrees that within the timeframe provided in the registration rights agreement between the Company and the holders of the Warrants, it shall use its best efforts to file with the Securities and Exchange Commission a registration statement for the registration under the Securities Act of 1933, as amended (the “Act”) of, among other securities, the Warrants and the shares of Common Stock issuable upon exercise of the Warrants (the “Registration Statement”), and it shall take such action as is necessary to qualify for sale, in those states in which the Warrants were initially offered by the Company, the Common Stock issuable upon exercise of the Warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such Registration Statement until the expiration of the Warrants in accordance with the provisions of this Agreement. In no event will the registered holder of a Warrant be entitled to receive a “net cash settlement” in lieu of physical settlement in shares of Common Stock, regardless of whether the Company complies with this Section 7.4.

7.5Limitation on Monetary Damages. In no event shall the registered holder of a Warrant be entitled to receive monetary damages for failure to settle any Warrant exercise if the Common Stock issuable upon exercise of the Warrants has not been registered with the Securities and Exchange Commission pursuant to an effective registration statement or if a current prospectus is not available for delivery by the Warrant Agent, provided the Company has fulfilled its obligations under Section 7.4 to use its best efforts to effect the registration under the Act of the Common Stock issuable upon exercise of the Warrants.

8.Concerning the Warrant Agent and Other Matters.

8.1Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of shares of Common Stock upon the exercise of Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares.

8.2Resignation, Consolidation, or Merger of Warrant Agent.

8.2.1Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

8.2.2Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the transfer agent for the Common Stock not later than the effective date of any such appointment.

8.2.3Merger or Consolidation of Warrant Agent. Any corporation into which the Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further act.

8.3Fees and Expenses of Warrant Agent.

8.3.1Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and will reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder.

8.3.2Further Assurances. The Company agrees to perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions of this Agreement.

8.4Liability of Warrant Agent.

8.4.1Reliance on Company Statement. Whenever in the performance of its duties under this Agreement the Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer, President, Executive Vice President, Secretary or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement.

8.4.2Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct or bad faith.

8.4.3Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant; nor shall it be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common Stock will when issued be valid and fully paid and nonassessable.

8.5Acceptance of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and, among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all moneys received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of Warrants.

9.Miscellaneous Provisions.

9.3Applicable Law. The validity, interpretation and performance of this Agreement and of the Warrants shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive.

9.4Persons Having Rights under this Agreement. Nothing in this Agreement expressed and nothing that may be implied from any of the provisions hereof is intended, or shall be construed, to confer upon, or give to, any person or corporation other than the parties hereto and the registered holders of the Warrants, any right, remedy, or claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations, promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors and assigns and of the registered holders of the Warrants.

9.5Examination of the Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the Warrant Agent in the Borough of Manhattan, City and State of New York, for inspection by the registered holder of any Warrant. The Warrant Agent may require any such holder to submit his, her or its Warrant for inspection by it.

9.6Counterparts. This Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

9.7Effect of Headings. The section headings herein are for convenience only and are not part of this Agreement and shall not affect the interpretation thereof.

This Agreement may be amended by the parties hereto without the consent of any registered holder for the purpose of curing any ambiguity, or correcting any mistake, including to conform the provisions of this Agreement to the description of the terms of the Warrants and this Agreement in the Registration Statement or curing, correcting or supplementing any defective provision contained herein or adding or changing any other provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable and that the parties deem shall not adversely affect the interest of the registered holders. All other modifications or amendments, including any amendment to increase the Warrant Price or shorten the Exercise Period, shall require the written consent of the registered holders of a majority of the then outstanding Warrants.
