Exhibit 4.2

WARRANT AGENCY AGREEMENT

This Warrant Agency Agreement (“Warrant Agreement”) is made as of August 15, 2022, by and among Athenex, Inc., a Delaware corporation (the “Company”), and Computershare Inc., a Delaware corporation (“Computershare”), and its affiliate Computershare Trust Company, N.A. a federally chartered trust company (collectively with Computershare, the “Warrant Agent”).

WHEREAS, the Company is conducting a public offering of units, each consisting of either (i) one share of common stock, par value $0.001 per share (the “Common Stock”) and one warrant, in substantially the form attached hereto as Exhibit A (the “Warrants”), entitling its holder to purchase one share of Common Stock for each whole warrant (the “Warrant Shares”); or (ii) one pre-funded warrant to purchase one share of Common Stock at an exercise price of $0.001 per share (each, a “Pre-Funded Warrant”) and a Warrant;

WHEREAS, the Company has filed, with the Securities and Exchange Commission (the “SEC”), a registration statement on Form S-3 (Registration No. 333-258185) (as amended, the “Registration Statement”), for the registration, under the Securities Act of 1933, as amended (the “Act”), of Common Stock, the Warrants, the Warrant Shares, the Pre-Funded Warrants, and the shares of Common Stock underlying the Pre-Funded Warrants;

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 Warrants (for the avoidance of doubt, this Warrant Agreement does not cover the issuance registration, transfer, exchange, redemption and exercise of the Pre-Funded Warrants);

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 legally valid and binding obligations of the Company, and to authorize the execution and delivery of this Warrant 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 express terms and conditions set forth in this Warrant Agreement.

2. Warrants.

2.1 Global Warrant. The Warrants, shall be issuable in book entry form (the “Global Warrants” and, each, a “Global Warrant”). All of the Warrants shall initially be represented by one or more Global Warrants, deposited with the Warrant Agent and registered in the name of Cede & Co., a nominee of The Depository Trust Company (the “Depositary”), or as otherwise directed by 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 Global Warrant or (ii) institutions that have accounts with the Depositary (such institution, with respect to

a Warrant in its account, a “Participant”). For purposes of Regulation SHO, a holder whose interest in a Global Warrant is a beneficial interest in certificate(s) representing such Warrant held in book-entry form through the Depositary shall be deemed to have exercised its interest in such Warrant upon instructing its broker that is a Participant to exercise its interest in such Warrant, provided that in each such case payment of the applicable aggregate Exercise Price (other than in the case of a cashless exercise) is received within the earlier of (i) two trading days and (ii) the number of trading days comprising the Standard Settlement Period, in each case following such instruction. As used herein, “Standard Settlement Period” means the standard settlement period, expressed in a number of trading days, on the Company’s primary trading market with respect to the Common Stock as in effect on the date of delivery of the Exercise Notice.

(b) If the Depositary subsequently ceases to make its book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding other arrangements for 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 Global Warrant, and the Company shall instruct the Warrant Agent in writing to deliver to each Holder a Warrant Certificate. The term “Warrant Certificate” means the Warrant Certificate in substantially the form attached as Exhibit A, representing such number of Warrant Shares as is indicated therein, provided that any reference to the delivery of a Warrant Certificate in this Agreement shall include delivery of notice from the Depositary or a Participant of the transfer or exercise of the Warrant in the form of a Global Warrant (as defined below).

(c) A Holder has the right to elect at any time or from time to time a Warrant Exchange (as defined below) pursuant to a Warrant Certificate Request Notice (as defined below). Upon written notice by a Holder to the Warrant Agent for the exchange of some or all of such Holder’s Global Warrants for a Warrant Certificate, evidencing the same number of Warrants, which request shall be in the form attached hereto as Exhibit B (a “Warrant Certificate Request Notice” and the date of delivery of such Warrant Certificate Request Notice by the Holder, the “Warrant Certificate Request Notice Date” and the deemed surrender upon delivery by the Holder of a number of Global Warrants for the same number of Warrants evidenced by a Warrant Certificate, a “Warrant Exchange”), the Warrant Agent shall promptly effect the Warrant Exchange and shall promptly issue and deliver, at the expense of the Company, to the Holder a Warrant Certificate, for such number of Warrants in the name set forth in the Warrant Certificate Request Notice. Such Warrant Certificate, shall be dated the original issue date of the Warrants, shall be executed by manual signature by an authorized signatory of the Company, shall be in the form attached hereto as Exhibit A. In connection with a Warrant Exchange, the Company agrees to deliver, or to direct the Warrant Agent to deliver, the Warrant Certificate, to the Holder within two (2) Business Days of the Warrant Certificate Request Notice pursuant to the delivery instructions in the Warrant Certificate Request Notice (“Warrant Certificate Delivery Date”). The Company covenants and agrees that, upon the date of delivery of the Warrant Certificate Request Notice, the Holder shall be deemed to be the holder of the Warrant Certificate.

2.2. Effect of Countersignature. Unless and until countersigned by the manual or facsimile signature of the Warrant Agent pursuant to this Warrant Agreement, a Certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.

2.3. Registration. The Warrant Agent will keep or cause to be kept, at its office designated for such purposes, books for registration and transfer of the Warrant Certificates issued hereunder. Such books shall show the names and addresses of the respective Holders of the Warrant Certificates, the number of warrants evidenced on the face of each of such Warrant Certificate and the date of each of such Warrant Certificate. The Warrant Agent will create a special account for the issuance of Warrant Certificates.

2.4. Separate Issuance of Warrants. The Common Stock and the Warrants shall be issued separately and shall be transferable separately immediately upon issuance.

2.5. Opinion of Counsel. The Company shall provide an opinion of counsel to the Warrant Agent prior to the issuance of the Warrants to set up a reserve of Warrant Shares. The opinion shall state that all Warrant Shares, as applicable, are:

(a) registered under the Securities Act of 1933, as amended, or are exempt from such registration, and all appropriate state securities law filings have been made with respect to the Warrant Shares; and

(b) validly issued, fully paid and non-assessable.

3. Terms and Exercise of Warrants.

3.1. Warrant Price. Each Warrant shall, when countersigned by the Warrant Agent, entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this Warrant Agreement, to purchase from the Company the number of shares of Common Stock stated therein, at the price of $1.00 per share of Common Stock, 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 Warrant Agreement refers to the price per whole share at which Common Stock may be purchased at the time such Warrant is exercised. The Company, in its sole discretion, may lower the Warrant Price at any time prior to the Termination Date (as defined below); provided, that any such reduction remains in effect for no less than ten (10) Business Days and shall be identical in percentage terms among all of the then outstanding Warrants. The Company shall promptly notify the Warrant Agent of any Warrant Price reduction. As used herein, “Registered Holder” and “Holder” shall include a Registered Holder’s and Holder’s transferees, successors and assigns and shall, if Warrants are held in “street name”, including a Participant or a designee appointed by such Participant.

3.2. Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the Issue Date (as defined in the Warrant Certificate) and terminating at 5:00 p.m., New York City time, on August 15, 2027 (“Termination Date”). With respect to each Warrant not exercised on or before the Termination Date, all rights to exercise the Warrant thereunder and under this Warrant Agreement shall cease at the close of business on the Termination Date. The Company may extend the duration of the Warrants by delaying the Termination Date; provided, however, that the Company will provide notice of not less than twenty (20) days to the Warrant Agent and Registered Holders of such extension and that such extension shall be identical in duration among all of the then outstanding Warrants.

3.3. Exercise of Warrants.

3.3.1. Payment. Subject to the provisions of the Warrant and this Warrant Agreement, a Warrant, when countersigned by the Warrant Agent, may be exercised by the Registered Holder thereof by surrendering at the office of the Warrant Agent, or at the office of its successor as Warrant Agent, at 150 Royall Street, Canton, Massachusetts 02021, (i) the Warrant Certificate evidencing the Warrants to be exercised, to the extent and only to the extent, required pursuant to the Warrant Certificate, or, in the case of the Global Warrant, the Warrants to be exercised shall be exercised as described herein and Section 2 of the Warrant, (ii) the notice of exercise, as set forth in the Warrant Certificate (the “Exercise Notice”), and, in the case of the Global Warrant, properly delivered by the Participant in accordance with the Depository’s procedures, and (iii), unless the cashless exercise

procedure specified in Section 2(c) of the Warrant is specified in the applicable Notice of Exercise (a “Registration Failure Cashless Exercise”), payment in full, in lawful money of the United States, in cash, by wire of same day funds or by certified or bank cashier’s check payable to the order of the Company, the Warrant Price for such number of Warrant Shares totaling whole shares 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 Warrant Shares, and the issuance of the Warrant Shares. Notwithstanding any other provision in this Warrant Agreement, a holder whose interest in a Warrant is a beneficial interest in the Global Warrant held through the Depository (or another established clearing corporation performing similar functions), shall effect exercises by delivering to the Depository (or such other clearing corporation, as applicable) the appropriate instruction form for exercise, complying with the procedures to effect exercise that are required by Depository (or such other clearing corporation, as applicable). Upon receipt of an Exercise Notice for a cashless exercise, the Company will promptly calculate and transmit to the Warrant Agent the number of Warrant Shares issuable in connection with such cashless exercise. The Warrant Agent shall have no duty or obligation to investigate or confirm whether the Company’s determination of the number of Warrant Shares to be issued on such exercise is accurate or correct. The Company hereby acknowledges and agrees that, with respect to a holder whose interest in a Warrant is a beneficial interest in the Global Warrant held through the Depository (or another established clearing corporation performing similar functions), upon delivery of irrevocable instructions to such holder’s Participant to exercise such warrants, that solely for purposes of Regulation SHO that such holder shall be deemed to have exercised such warrants.

3.3.2. Fractional Shares. Notwithstanding any provision to the contrary contained in this Warrant Agreement, the Company shall not be required to issue any fractional shares of Common Stock in connection with the exercise of Warrants for Warrant Shares, and in any case where the Registered Holder would be entitled under the terms of the Warrants to receive a fractional share of Common Stock as a Warrant Share upon the exercise of such Registered Holder’s Warrants, issue or cause to be issued only the largest whole number of aggregate Warrant Shares issuable on such exercise (and such remaining fractional shares will be rounded up to the nearest whole share); provided, that if more than one Warrant Certificate is presented for exercise at the same time by the same Registered Holder, the number of Warrant Shares which shall be issuable upon the exercise thereof shall be computed on the basis of the aggregate number of Warrant Shares issuable on exercise of all such Warrants.

3.3.3. Issuance of Common Stock. As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price, the Warrant Agent shall advise the Company and its transfer agent regarding (i) the number of Warrant Shares issuable upon such exercise in accordance with the terms and conditions of this Warrant Agreement, (ii) the instructions of each Holder or Participant, as they case may be, with respect to delivery of the Warrant Shares issuable upon such exercise, (iii) in case of the Global Warrant, the notation that shall be made to the records maintained by the Depository, its nominee for the Global Warrant, or a Participant, as appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise and (iv) such other information as the Company or such transfer agent and registrar shall reasonably require. Promptly thereafter and within the time period set forth in the Warrants, the Company shall instruct its transfer agent to issue to the Registered Holder of such Warrant the number of full shares of Common Stock to which the Registered Holder is entitled, registered in such

name or names as may be directed by the Registered Holder according to Section 2(d)(i) of the Warrant Certificate. If such Warrant shall not have been exercised or surrendered in full, in case of the Global Warrant, a notation shall be made to the records maintained by the Depository or nominee for the Global Warrant, evidencing the balance, if any, 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 Registered Holder of the Warrant or (b) in the absence of a registration statement under the Act with respect to the Common Stock and a current prospectus relating to the shares of Common Stock, 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; provided that in the case of a cashless exercise, no registration statement under the Act with respect to the Common Stock and no current prospectus relating to the shares of Common Stock, and no opinion of counsel shall be required. Until otherwise advised in writing by the Company, the Warrant Agent shall always be entitled to assume that either clause (a) or clause (b) is in effect and shall incur no liability in making such assumption. 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 a 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. Except as set forth in Section 3(d) of the Warrant Certificate, in no event will the Company be obligated to pay such Registered Holder any cash consideration upon exercise or otherwise “net cash settle” the Warrant.

3.3.4. Valid Issuance. The validity of any exercise of Warrants will be determined by the Company in its reasonable discretion. The Warrant Agent shall notify a holder of any purported invalidity of any exercise of Warrants. All shares of Common Stock issued upon the proper exercise or surrender of a Warrant in conformity with this Warrant Agreement shall be validly issued, fully paid and nonassessable.

3.3.5. Date of Issuance. Each person in whose name any shares of Common Stock is issued shall, for all purposes (other than for purposes of Regulation SHO, which are specified elsewhere in this Agreement), be deemed to have become the holder of record of such shares on the date on which the Warrant was exercised and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate, except that, if the date of such exercise and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the stock transfer books are open (the “Exercise Date”). If a Warrant is exercised after 5:00 P.M., New York time, on the specified Exercise Date, the Warrants will be deemed exercised on the Business Day next succeeding the Exercise Date, subject to clearance of the funds. If the date specified as the Exercise Date is not a Business Day, the Warrants will be deemed to be received and exercised on the next succeeding day that is a Business Day, subject to clearance of the funds. If the Warrants are exercised after the Termination Date, the exercise thereof will be null and void and any funds delivered to the Warrant Agent will be returned to the Registered Holder as soon as practicable.

3.3.6. Cost Basis Information.

(a) In the event of a cash exercise, the Company hereby instructs the Warrant Agent to record cost basis for newly issued shares in a manner to be subsequently communicated by the Company in writing to the Warrant Agent.

(b) In the event of a cashless exercise, the Company shall provide cost basis for shares issued pursuant to a cashless exercise at the time the Company confirms the number of Warrant Shares issuable in connection with the cashless exercise to the Warrant Agent pursuant to Section 3.3.1 hereof.

4. Adjustments; Rights. The Warrant Shares and Warrant Price shall be subject to adjustment as provided for in the Warrant, and the rights of Warrant holders as provided for in the Warrant are incorporated herein by reference and shall be adhered to by the Company and the Warrant Agent. The Company hereby agrees that it will provide the Warrant Agent with reasonable notice of any adjustment events. The Company further agrees that it will provide to the Warrant Agent with any new or amended exercise terms. Whenever the Warrant Shares or Warrant Price or the number of shares of Common Stock issuable upon the exercise of each Warrant is adjusted, the Company shall (a) promptly prepare a certificate setting forth the Warrant Price of each Warrant as so adjusted, and a brief statement of the facts accounting for such adjustment, (b) promptly file with the Warrant Agent and with each transfer agent for the Common Stock a copy of such certificate and (c) instruct the Warrant Agent to send a brief summary thereof to each Holder of a Warrant Certificate. The Warrant Agent shall be fully protected in relying on any such certificate and on any adjustment or statement therein contained and shall have no duty or liability with respect to, and shall not be deemed to have knowledge of any such adjustment or any such event unless and until it shall have received such certificate.

5. Transfer and Exchange of Warrants.

5.1. Transfer of Warrants. The Warrants may be transferred or exchanged separately from shares of Common Stock.

5.2. Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant Certificate into the Warrant Register, upon surrender of such Warrant Certificate for transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer, or properly noticed by the Depository as contemplated by Section 5.3. Upon any such transfer, a new Warrant Certificate, representing an equal aggregate number of Warrant Certificates shall be issued and the old Warrant Certificate shall be cancelled by the Warrant Agent. The Warrant Certificates so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon the Company’s request and at the Company’s expense. A party requesting transfer of Warrant Certificates must provide any evidence of authority that may be required by the Warrant Agent, including but not limited to, a signature guarantee from an eligible guarantor institution participating in a signature guarantee program approved by the Securities Transfer Association.

5.3. Procedure for Surrender of Warrant Certificates. Warrant Certificates may be surrendered to the Warrant Agent, together with a written request for exchange or transfer reasonably acceptable to Warrant Agent, duly executed by the registered holder thereof, or by a duly authorized attorney, and, thereupon, the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrant Certificates so surrendered, representing an equal aggregate number of Warrant Certificates; provided, however, that, except as otherwise provided herein or in the Global Warrant, each interest in the Global Warrant may be transferred

only in whole and only to the Depository, to another nominee of the Depository, to a successor depository, or to a nominee of a successor depository; provided further, that in the event a Warrant Certificate surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant Certificate and issue new Warrant Certificates in exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrant Certificates must also bear a restrictive legend. Notwithstanding anything else in this Section 5.3, in case of the Global Warrant, the holder or Participant shall notify the Depository in accordance with the Depository’s procedures of a requested transfer and the Depository shall provide notice to an account of the Warrant Agent at the Depository designated for such purpose in writing by the Warrant Agent to the Depository from time to time, of a transfer to be recorded in the records maintained by the Depository, its nominee for the Global Warrant, or a Participant, as appropriate, evidencing the balance, if any, of the Warrants remaining after such transfer and the new name in which the transferred interest in the Global Warrant is to be held.

5.4. Fractional 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 for a fraction of a Warrant.

5.5. Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Warrant Agreement, the Warrant Certificates 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. Other Provisions Relating to Rights of Registered Holders of Warrants.

6.1. No Rights as Stockholder. Except as expressly provided in Section 3 of the Warrant, 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.

6.2. Lost, Stolen Mutilated or Destroyed Warrants. If any Warrant Certificate is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may, absent notice to Warrant Agent that such certificates have been acquired by a bona fide purchaser, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall in all cases include posting of a lost security bond by or on behalf of the Registered Holder holding the Warrant Agent and the Company harmless, and in the case of a mutilated Warrant Certificate, include the surrender thereof), issue a new Warrant Certificate of like denomination, tenor and date as the Warrant Certificate so lost, stolen, mutilated or destroyed. Any such new Warrant Certificate shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated or destroyed Warrant Certificate shall be at any time enforceable by anyone.

6.3. Reservation 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 Warrant Agreement.

6.4. Registration of Common Stock. The Company agrees to use its commercially reasonable efforts to maintain the effectiveness of the Registration Statement until the expiration of the Warrants in accordance with the provisions of this Warrant Agreement; provided, however, that

the Company shall not have penalties for failure to deliver Common Stock if a registration statement is not effective or a current prospectus is not on file with the SEC at the time of exercise by the Registered Holder. In addition, to the extent not completed at the time of the initial issuance of the Warrants, the Company agrees to use its reasonable efforts to register such securities under the blue sky laws of the states of residence of the exercising Registered Holders to the extent an exemption under the Act is not available for the exercise of the Warrants. In no event will the Registered Holder of a Warrant be entitled to receive a net-cash settlement or shares of Common Stock or other consideration as of result of the Company’s non-compliance with this Section 6.4.

7. Concerning the Warrant Agent and Other Matters.

7.1. Payment 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 neither the Company nor the Warrant Agent shall be obligated to pay any transfer taxes in respect of the Warrants or such shares. The Warrant Agent shall not register any transfer or issue or deliver any Warrant Certificate(s) or Warrant Shares unless or until the persons requesting the registration or issuance shall have paid to the Warrant Agent for the account of the Company the amount of such tax, if any, or shall have established to the reasonable satisfaction of the Company and the Warrant Agent that such tax, if any, has been paid.

7.2. Resignation, Consolidation, or Merger of Warrant Agent.

7.2.1. Appointment 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 thirty (30) 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 thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the Registered Holder of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then the Registered 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. Any successor Warrant Agent, whether appointed by the Company or by such court, shall be an entity authorized under applicable laws to exercise the powers of a transfer agent and subject to supervision or examination by federal or state authorities. 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.

7.2.2. Notice 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 thirty (30) days before the effective date of any such appointment.

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

7.2.4. Confidentiality. The Warrant Agent and the Company agree that all books, records, information and data pertaining to the business of the other party, including inter alia, personal, non-public Holder information, which are exchanged or received pursuant to the negotiation or the carrying out of this Warrant Agreement including the fees for services set forth in the attached schedule shall remain confidential, and shall not be voluntarily disclosed to any other person, except as may be required by law, including, without limitation, pursuant to subpoenas from state or federal government authorities.

7.3. Fees and Expenses of Warrant Agent.

7.3.1. Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as Warrant Agent hereunder as set forth in the fee schedule mutually agreed upon by the parties 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.

7.3.2. Further 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 Warrant Agreement.

7.4. Liability of Warrant Agent.

7.4.1. Reliance on Company Statement. Whenever, in the performance of its duties under this Warrant 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 or Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon, and be held harmless for such reliance, such statement for any action taken or suffered or omitted to be taken by it in the absence of bad faith pursuant to the provisions of this Warrant Agreement, and shall not be held liable in connection with any delay in receiving such statement.

7.4.2. Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith (each as determined by a final, non-appealable judgment of a court of competent jurisdiction). The Company covenants and agrees to indemnify the Warrant Agent and hold it harmless against any and all liabilities, including judgments, losses, damages, costs, expenses, and reasonable counsel fees, which may be paid, incurred or suffered by or to which it may become subject, arising from or out of, directly or indirectly, any claims or liability resulting from its actions as Warrant Agent

pursuant hereto; provided, that such covenant and agreement does not extend to, and the Warrant Agent shall not be indemnified with respect to, such costs, expenses, losses and damages incurred or suffered by the Warrant Agent as a result of, or arising out of, its gross negligence, willful misconduct or bad faith (each as determined by a final, non-appealable judgment of a court of competent jurisdiction).

7.4.3. Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Warrant 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 Warrant 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 Warrant Agreement or any Warrant or as to whether any shares of Common Stock will when issued be valid and fully paid and nonassessable.

7.4.4. Instructions. From time to time, the Company may provide the Warrant Agent with instructions concerning the services performed by the Warrant Agent hereunder. In addition, at any time the Warrant Agent may apply to any officer of Company for instruction, and may consult with legal counsel for the Warrant Agent or the Company with respect to any matter arising in connection with the services to be performed by the Warrant Agent under this Warrant Agreement. Warrant Agent and its agents and subcontractors shall not be liable and shall be indemnified by Company for any action taken, suffered or omitted to be taken by Warrant Agent in reliance upon any Company instructions or upon the advice or opinion of such counsel. Warrant Agent shall not be held to have notice of any change of authority of any person, until receipt of written notice thereof from Company.

7.4.5. Rights and Duties of Warrant Agent.

(a) The Warrant Agent may consult with legal counsel (who may be legal counsel for the Company), and the advice or opinion of such counsel shall be full and complete authorization and protection to the Warrant Agent as to any action taken, suffered or omitted by it in accordance with such advice or opinion.

(b) The Warrant Agent shall not be liable for or by reason of any of the statements of fact or recitals contained in this Warrant Agreement or in the Warrant Certificates (except its countersignature thereof) or be required to verify the same, and all such statements and recitals are and shall be deemed to have been made by the Company only.

(c) The Warrant Agent shall not be required to take notice or be deemed to have notice of any event or condition hereunder, including any event or condition that may require action by the Warrant Agent, unless the Warrant Agent shall be specifically notified in writing of such event or condition by the Company, and all notices or other instruments required by this Warrant Agreement to be delivered to the Warrant Agent must, in order to be effective, be received by the Warrant Agent as specified in Section 8.2 hereof, and in the absence of such notice so

delivered, the Warrant Agent may conclusively assume no such event or condition exists.

(d) The Warrant Agent and any stockholder, director, officer or employee of the Warrant Agent may buy, sell or deal in any of the Warrants or other securities of the Company or become pecuniarily interested in any transaction in which the Company may be interested, or contract with or lend money to the Company or otherwise act as fully and freely as though it were not Warrant Agent under this Warrant Agreement.
