THE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS.

PRE-FUNDED COMMON STOCK PURCHASE WARRANT NEKTAR THERAPEUTICS

THIS PRE-FUNDED COMMON STOCK PURCHASE WARRANT (the “Warrant”) certifies that, for value received, TCG Crossover Fund II, L.P., or its registered assigns (the “Holder”) is entitled, upon the terms and subject to the limitations on exercise and the conditions hereinafter set forth, at any time on or after the Issue Date set forth above (the “Initial Exercise Date”), to subscribe for and purchase from Nektar Therapeutics, a Delaware corporation (the “Company”), up to 25,000,000 shares (as subject to adjustment hereunder, the “Warrant Shares”) of common stock, par value $0.0001 per share, of the Company (the “Common Stock”). The purchase price of one share of Common Stock under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).

This Warrant is issued pursuant to that certain Securities Purchase Agreement, dated March [ ], 2024, by and among the Company and the Purchaser identified therein (the “Purchase Agreement”). This Warrant and all new warrants, if any, issued by the Company pursuant to Section 4 hereof are referred to herein, collectively, as the “Warrants.”

Section 1. Definitions; Purchase Agreement. Capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Purchase Agreement. For the avoidance of doubt, whenever this Warrant references terms of, or provisions being in accordance with provisions of, the Purchase Agreement, such terms and provisions of the Purchase Agreement shall be deemed incorporated into this Warrant and to be part hereof as though set forth herein.

Section 2. Exercise.

(a) Exercise of Warrant. This Warrant may be exercised, in whole or in part, at any time or times on or after the Initial Exercise Date by delivery to the Company of a duly executed PDF copy submitted by e-mail (or e-mail attachment) of the Notice of

Exercise in the form annexed hereto (the “Notice of Exercise”). Within two (2) Trading Days following the date of exercise, the Holder shall deliver the aggregate Exercise Price for the Warrant Shares specified in the applicable Notice of Exercise by wire transfer or cashier’s check drawn on a United States bank, unless the cashless exercise procedure referenced in Section 2(c) below is specified in the applicable Notice of Exercise. No ink-original Notice of Exercise shall be required, nor shall any medallion guarantee (or other type of guarantee or notarization) of any Notice of Exercise be required. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company to effect an exercise hereunder until the Holder has purchased all of the Warrant Shares available hereunder and the Warrant has been exercised in full, in which case, the Holder shall surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date on which the final Notice of Exercise is delivered to the Company. (It is understood and agreed that to surrender this Warrant to the Company for any purpose under this Warrant, the Holder only needs to e-mail to the Company e-mail address provided in Section 5(h) an electronic copy of the Warrant and state such Holder’s intent to surrender the Warrant.) Partial exercise of this Warrant shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the number of Warrant Shares set forth in the applicable Notice of Exercise. The Holder and the Company shall maintain records showing the number of Warrant Shares purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise within one (1) Trading Day of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

(b) Exercise Price. The aggregate exercise price of this Warrant, except for a nominal exercise price of $0.0001 per Warrant Share, was pre-funded to the Company on or prior to the Initial Exercise Date and, consequently, no additional consideration (other than the nominal exercise price of $0.0001 per Warrant Share) shall be required to be paid by the Holder to any Person to effect any exercise of this Warrant. The Holder shall not be entitled to the return or refund of all, or any portion, of such pre-paid aggregate exercise price under any circumstance or for any reason whatsoever. The remaining unpaid exercise price per share of Common Stock under this Warrant shall be $0.0001, subject to adjustment hereunder (the “Exercise Price”).

(c) Cashless Exercise. Notwithstanding anything contained herein to the contrary, this Warrant may also be exercised, in whole or in part, at such time by means of a “cashless exercise” in which the Holder shall be entitled to receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where:

(A) = as applicable: (i) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise if such Notice of Exercise is (1) both executed and delivered pursuant to Section 2(a) hereof on a day that is not a Trading Day or (2) both executed and delivered pursuant to Section 2(a) hereof on a Trading Day prior to the opening of “regular trading hours” (as defined in Rule 600(b) of Regulation NMS promulgated under the federal securities laws) on such Trading Day, (ii)

at the option of the Holder, either (y) the VWAP on the Trading Day immediately preceding the date of the applicable Notice of Exercise or (z) the Bid Price of the Common Stock on the principal Trading Market as reported by Bloomberg L.P. as of the time of the Holder’s execution of the applicable Notice of Exercise if such Notice of Exercise is executed during “regular trading hours” on a Trading Day and is delivered within two (2) hours thereafter (including until two (2) hours after the close of “regular trading hours” on a Trading Day) pursuant to Section 2(a) hereof or (iii) the VWAP on the date of the applicable Notice of Exercise if the date of such Notice of Exercise is a Trading Day and such Notice of Exercise is both executed and delivered pursuant to Section 2(a) hereof after the close of “regular trading hours” on such Trading Day;

(B) = the Exercise Price of this Warrant, as adjusted hereunder; and

(X) = the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash exercise rather than a cashless exercise.

If Warrant Shares are issued in such a cashless exercise, the parties acknowledge and agree that in accordance with Section 3(a)(9) of the Securities Act, the Warrant Shares shall take on the characteristics of the Warrants being exercised, and the holding period of the Warrant Shares being issued may be tacked on to the holding period of this Warrant. The Company agrees not to take any position contrary to this Section 2(c).

“Bid Price” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the bid price of the Common Stock for the time in question (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on the Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holders of a majority in interest of the Warrants then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

“VWAP” means, for any date, the price determined by the first of the following clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market, the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (New York City time)), (b) if OTCQB or OTCQX is not a Trading Market, the volume weighted average price of the Common Stock for such date (or the nearest preceding date) on OTCQB or OTCQX

as applicable, (c) if the Common Stock is not then listed or quoted for trading on OTCQB or OTCQX and if prices for the Common Stock are then reported on the Pink Open Market (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Holders of a majority in interest of the Warrants then outstanding and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the Company.

(d) Mechanics of Exercise.

i Delivery of Warrant Shares Upon Exercise. The Company shall cause the Warrant Shares purchased hereunder to be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s or its designee’s balance account with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A) there is an effective registration statement permitting the issuance of the Warrant Shares to or resale of the Warrant Shares by the Holder or (B) the Warrant Shares are eligible for resale by the Holder without volume or manner- of-sale limitations pursuant to Rule 144 (assuming cashless exercise of the Warrants), and otherwise by physical delivery of a certificate (or evidence of issuance of the Warrant Shares in book entry with the Transfer Agent), registered in the Company’s share register in the name of the Holder or its designee, for the number of Warrant Shares to which the Holder is entitled pursuant to such exercise to the address specified by the Holder in the Notice of Exercise (or, in the case of book entry issuance of Warrant Shares, evidence of such issuance to the email address specified in such Notice of Exercise) by the date that is the earliest of (i) two (2) Trading Days after the delivery to the Company of the Notice of Exercise, and (ii) one (1) Trading Day after delivery of the aggregate Exercise Price to the Company (provided that the foregoing clause (ii) shall not apply in the case of cashless exercise) (such date, the “Warrant Share Delivery Date”). Upon delivery of the Notice of Exercise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with respect to which this Warrant has been exercised, irrespective of the date of delivery of the Warrant Shares, provided that payment of the aggregate Exercise Price (other than in the case of a cashless exercise) is received within two (2) Trading Days following delivery of the Notice of Exercise. The Company agrees to maintain a transfer agent that is a participant in the FAST program so long as this Warrant remains outstanding and exercisable.

ii Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical to this Warrant.

iii Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise by delivering written notice (including by email) to the Company at any time prior to the delivery of the Warrant Shares.

iv No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant. As to any fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price or round up to the next whole share.

v Charges, Taxes and Expenses. Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense in respect of the issuance of such Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder in the Notice of Exercise; provided, however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by the Assignment Form attached hereto duly executed by the Holder and the Company shall have the right to require, as a condition thereto, the prior or contemporaneous payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. The Company shall pay all Transfer Agent fees required for same-day processing of any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares, in each case, if applicable.

vi Closing of Books. The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to the terms hereof.

(e) Beneficial Ownership Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this Warrant, pursuant to Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, the Holder (together with the Holder’s Affiliates, and any Person acting as a group together with such Holder or any of such Holder’s Affiliates (including such group itself), any other Person who is a beneficial owner of Common Stock beneficially owned by the Holder or any of its Affiliates and any other Person whose beneficial ownership would or could be aggregated with the Holder and the foregoing Persons, collectively, the “Attribution Parties”), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its Attribution Parties shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made plus any shares of Common Stock then held whether issued following exercise of the Warrant or otherwise acquired, but shall exclude the number of shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Attribution Parties and (ii) exercise or conversion of the unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Warrant) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its Attribution Parties. Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules

required to be filed in accordance therewith. For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company or (C) a more recent written notice by the Company or the Transfer Agent setting forth the number of shares of Common Stock outstanding. Upon the written request of a Holder, the Company shall within one (1) Trading Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or Attribution Parties since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 9.99% of the number of shares of the Common Stock outstanding (for purposes of the denominator, immediately after giving effect to the issuance of shares of Common Stock to be issued upon the applicable exercise of this Warrant). The Holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(e), provided that the Beneficial Ownership Limitation in no event exceeds 19.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the Holder and the provisions of this Section 2(e) shall continue to apply. Any increase in the Beneficial Ownership Limitation will not be effective until the 61st day after such notice is delivered to the Company. Any purported delivery to the Holder or the Attribution Parties of a number of shares of Common Stock or any other security upon exercise of any Warrant shall be void and have no effect to the extent, but only to the extent, that before or after such delivery, the Holder and the Attribution Parties would have beneficial ownership of Common Stock or any other such class in excess of the Beneficial Ownership Limitation. The limitations contained in this paragraph may not be waived and shall apply to a successor holder of this Warrant.

Section 3. Certain Adjustments.

(a) Stock Dividends and Splits. If the Company, at any time on or after the date of the Purchase Agreement and while this Warrant is outstanding: (i) pays a stock dividend or otherwise makes a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock (which, for avoidance of doubt, shall not include any shares of Common Stock issued by the Company upon exercise of this Warrant), (ii) subdivides outstanding shares of Common Stock into a larger number of shares, (iii) combines (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares or (iv) issues by reclassification of shares of the Common Stock any shares of capital stock of the Company, then in each case the Exercise Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding immediately before such event and of which the denominator shall be the number of shares of Common Stock outstanding immediately after such event, and the number of shares issuable upon exercise of this Warrant shall be proportionately adjusted such that the aggregate Exercise Price of this Warrant shall remain unchanged. Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the effective date of the dividend, distribution, subdivision, combination or re-classification.

(b) Subsequent Rights Offerings. In addition to any adjustments pursuant to Section 3(a) above, if at any time the Company grants, issues or sells any Common Stock Equivalents or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of shares of Common Stock (the “Purchase Rights”), then the Holder will be entitled to acquire, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date on which a record is taken for the grant, issuance or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that, to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Purchase Right to such extent (or beneficial ownership of such shares of Common Stock as a result of such Purchase Right to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation).

(c) Pro Rata Distributions. During such time as this Warrant is outstanding, if the Company shall declare or make any dividend or other distribution of its assets (or rights to acquire its assets) to holders of shares of Common Stock, by way of return of capital or otherwise (including, without limitation, any distribution of cash, stock or other securities, property or options by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (a “Distribution”), at any time after the issuance of this Warrant, then, in each such case, the Holder shall be entitled to participate in such Distribution to the same extent that the Holder would have participated therein if the Holder had held the number of shares of Common Stock acquirable upon complete exercise of this Warrant (without regard to any limitations on exercise hereof, including without limitation, the Beneficial Ownership Limitation) immediately before the date of which a record is taken for such Distribution, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the participation in such Distribution (provided, however, that, to the extent that the Holder’s right to participate in any such Distribution would result in the Holder exceeding the Beneficial Ownership Limitation, then the Holder shall not be entitled to participate in such Distribution to such extent (or in the beneficial ownership of any shares of Common Stock as a result of such Distribution to such extent) and the portion of such Distribution shall be held in abeyance for the benefit of the Holder until such time, if ever, as its right thereto would not result in the Holder exceeding the Beneficial Ownership Limitation). To the extent that this Warrant has not been partially or completely exercised at the time of such Distribution, such portion of the Distribution shall be held in abeyance for the benefit of the Holder until the Holder has exercised this Warrant.

(d) Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company (including without limitation through a Subsidiary), directly or indirectly, in one or more related transactions effects any merger or consolidation of the Company with or into another Person, (ii) the Company directly or indirectly, effects any sale, lease, license, assignment, transfer, conveyance or other disposition of all or substantially all of its assets in one or a series of related transactions, (iii) any, direct or indirect, purchase offer, tender offer or exchange offer

(whether by the Company or another Person) is completed pursuant to which holders of Common Stock are permitted to sell, tender or exchange their shares for other securities, cash or property and has been accepted for shares representing more than 50% of the outstanding Common Stock or more than 50% of the voting power of the common equity of the Company, (iv) the Company, directly or indirectly, in one or more related transactions effects any reclassification, reorganization or recapitalization of the Common Stock or any compulsory share exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property, or (v) the Company, directly or indirectly, in one or more related transactions (other than one or more bona fide financing transactions) consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off, merger or scheme of arrangement) with another Person or group of Persons whereby such other Person or group acquires more than 50% of the outstanding shares of Common Stock or more than 50% of the voting power of the common equity of the Company (“group” status being determined in accordance with Section 13(d) of the Exchange Act) (each a “Fundamental Transaction”), to the extent any portion to this Warrant remains unexercised, then following such Fundamental Transaction the Holder shall have the right to receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as the Holder would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein (the “Alternate Consideration”). If the Company undertakes a Fundamental Transaction in which the Company is not the surviving entity and the Alternate Consideration includes securities of another Person, then the Company shall provide that, prior to or simultaneously with the consummation of such Fundamental Transaction, any successor to the Company, surviving entity or other Person (including any purchaser of assets of the Company) shall assume the obligation to deliver to the Holder such Alternate Consideration as the Holder is entitled to receive in accordance with the foregoing provisions, and to assume the other obligations under this Warrant. The provisions of this paragraph (d) shall similarly apply to subsequent transactions analogous of a Fundamental Transaction type.

(e) Calculations. All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 3, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock (excluding treasury shares, if any) issued and outstanding.

(f) Notice to Holder.

i Adjustment to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly deliver to the Holder by email a notice setting forth the Exercise Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

ii Notice to Allow Exercise by Holder. If during the term in which the Warrant may be exercised (A) the Company shall declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting

to all holders of the Common Stock rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other securities, cash or property, or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be delivered by email to the Holder at its last email address as it shall appear upon the Warrant Register of the Company, at least 10 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification, consolidation, merger, sale, transfer or share exchange; provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice. The Holder shall remain entitled to exercise this Warrant during the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

Section 4. Transfer of Warrant.

(a) Transferability. Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof and to the provisions of Section 4.1 of the Purchase Agreement, this Warrant and all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company, unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this Warrant to the Company within three (3) Trading Days of the date on which the Holder delivers a duly executed Assignment Form to the Company assigning this Warrant in full. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

(b) New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the initial issuance date of this Warrant and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

(c) Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other purposes, absent actual notice to the contrary.

(d) Transfer Restrictions. If, in connection with the transfer of this Warrant, the transfer shall not be either (i) registered pursuant to an effective registration statement under the Securities Act and under applicable state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the Holder or transferee of this Warrant, as the case may be, comply with the provisions of Section 4.1 of the Purchase Agreement.

(e) Representation by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise hereof, will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities law, except pursuant to sales registered or exempted under the Securities Act.

Section 5. Miscellaneous.

(a) No Rights as Stockholder Until Exercise; No Settlement in Cash. This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3. Without limiting any rights of a Holder to receive Warrant Shares in a “cashless exercise” pursuant to Section 2(c) or to receive cash payments pursuant to Section 2(d)(iv) and Section 2(d)(v) herein, in no event shall the Company be required to net cash settle an exercise of this Warrant.

(b) Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation, in lieu of such Warrant or stock certificate.

(c) Saturdays, Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or granted herein shall not be a Trading Day, then, such action may be taken or such right may be exercised on the next succeeding Trading Day.

(d) Authorized Shares. The Company covenants that, during the period the Warrant is outstanding, it will reserve from its authorized and unissued Common Stock a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant. The Company will take all such reasonable action as may be necessary to assure that such Warrant Shares may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock may be listed. The Company covenants that all Warrant Shares which may be issued upon the exercise of the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its certificate of incorporation or through any 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 of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality of the foregoing, the Company will, so long as any of the Warrants are outstanding, (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all such action as may be necessary or appropriate in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares upon the exercise of this Warrant and (iii) use commercially reasonable efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.

Before taking any action which would result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public regulatory body or bodies having jurisdiction thereof.

(e) Jurisdiction. All questions concerning the construction, validity, enforcement and interpretation of this Warrant shall be determined in accordance with the provisions of the Purchase Agreement.

(f) Restrictions. The Holder acknowledges that the Warrant Shares acquired upon the exercise of this Warrant, if not registered and the Holder does not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.

(g) Nonwaiver. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder shall operate as a waiver of such right or otherwise prejudice the Holder’s rights, powers or remedies.

(h) Notices. Any notice, request or other document required or permitted to be given or delivered to the Holder by the Company shall be delivered in accordance with the notice provisions of the Purchase Agreement. Any notice, request or other document required or permitted to be given or delivered to the Company by the Holder shall be delivered via email to [***].

(i) Limitation of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by creditors of the Company.

(j) Remedies. The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to seek specific performance of its rights under this Warrant. The Company agrees that monetary damages may not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert the defense in any action for specific performance that a remedy at law would be adequate.

(k) Successors and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares.

(l) Amendment; Waiver. The provisions of the Warrants may be modified or amended, or the provisions hereof waived only with the written consent of the Company and the Holder.

(m) Severability. Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Warrant.

(n) Headings. The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of this Warrant.

4.1 Organization and Standing; Subsidiaries. The Company has been duly incorporated or organized and is validly existing and in good standing under the laws of Delaware or other jurisdiction of incorporation or organization, has full corporate or other power and authority necessary to own or lease its properties and conduct its business as presently conducted, and is duly qualified as a foreign corporation and in good standing in all jurisdictions in which the character of the property owned or leased or the nature of the business transacted by it makes qualification necessary, except where the failure to be so qualified would not have a Material Adverse Effect. The Company has no material subsidiaries.

4.2 Corporate Power; Authorization. The Company has all requisite corporate power and authority, and the Company and its Board of Directors have taken all requisite corporate action, to authorize, execute and deliver this Agreement and the Pre-Funded Warrant, to consummate the transactions contemplated herein and therein, including to sell, issue and deliver the Securities to the Purchaser, and to carry out and perform all of the Company’s obligations hereunder and thereunder. This Agreement has been duly authorized, executed and delivered by the Company and constitutes the legal, valid and binding obligation of the Company, enforceable against the Company in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting the enforcement of creditors’ rights generally and (ii) as limited by equitable principles generally, including any specific performance.

4.3 Issuance and Delivery of the Securities. The Pre-Funded Warrant has been duly authorized by the Company and when executed and delivered by the Company will be a valid and binding agreement of the Company, enforceable against the Company in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles. The issuance and delivery of the Pre-Funded Warrant is not subject to preemptive, co-sale, right of first refusal or any other similar rights of the stockholders of the Company or any other Person or any liens, encumbrances or restrictions, other than encumbrances under applicable securities laws. The Warrant Shares have been duly authorized and reserved for issuance and, when issued and delivered upon valid exercise of the Pre-Funded Warrant in accordance therewith, will be validly issued, fully paid and nonassessable, and not subject to preemptive, co-sale, right of first refusal or any other similar rights of the stockholders of the Company or any other Person or any liens, encumbrances or restrictions, other than encumbrances under applicable securities laws or the Pre-Funded Warrant. Assuming the accuracy of the representations made by the Purchaser in Section 5, the offer and issuance by the Company of the Securities is exempt from registration under the Securities Act of 1933, as amended (the “Securities Act”).

5

4.4 SEC Documents; Financial Statements; Independent Accountants. The Company is not an “ineligible issuer” (as defined in Rule 405 promulgated under the Securities Act). The Company is subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and has filed or furnished or will file or furnish in a timely manner all reports, schedules, forms, statements and other documents that the Company was or is required to file with the Commission under either the Securities Act or the Exchange Act, for the one year preceding the date hereof (the foregoing documents (together with any documents filed by the Company under the Securities Act or Exchange Act, whether or not required), and in each case including all exhibits and schedules thereto and documents incorporated by reference therein and including all registration statements and prospectuses filed with the Commission, but excluding any information for which the Company has received confidential treatment from the Commission, being collectively referred to herein as the “SEC Documents”). As of their respective filing or furnishing dates (or, if amended prior to the date of this Agreement, when amended), all SEC Documents (including any audited or unaudited financial statements and any notes thereto or schedules included therein) complied in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the Commission promulgated thereunder. None of the SEC Documents as of their respective filing or furnishing dates contained any untrue statement of material fact or omitted to state a material fact required to be stated therein or necessary to make the statements made therein, in light of the circumstances under which they were made, not misleading. There are no material outstanding or unresolved comments in comment letters from the staff of the Division of Corporation Finance of the Commission with respect to any SEC Documents. The Company meets all requirements for the use of Form S-3 under the Securities Act. The financial statements (including the notes thereto) of the Company set forth in the SEC Documents (the “Financial Statements”) comply in all material respects with applicable accounting requirements and with the published rules and regulations of the Commission with respect thereto. The Financial Statements have been prepared in accordance with GAAP consistently applied during the periods involved and fairly present the financial position of the Company at the dates thereof and the results of its operations and cash flows for the periods then ended (subject, in the case of unaudited statements, to normal recurring adjustments). Except as set forth in the Financial Statements filed prior to the date hereof, the Company has not incurred any liabilities, contingent or otherwise, except those incurred in the ordinary course of business, consistent (as to amount and nature) with past practices since the date of such Financial Statements, none of which, individually or in the aggregate, have had or would reasonably be expected to have a Material Adverse Effect. The accountants who certified the Financial Statements are independent public accountants as required by the Securities Act and the Exchange Act and the regulations thereunder and the Public Company Accounting Oversight Board.

4.5 Capitalization. The authorized capital stock of the Company consists of 300,000,000 shares of Common Stock and 10,000,000 shares of preferred stock. As set forth in the SEC Documents as of the date set forth therein, all of the Company’s outstanding shares of capital stock have been duly authorized and validly issued and are fully paid and nonassessable, have been issued in compliance with all federal and state securities laws, and were not issued in violation of or subject to any preemptive right or other rights to subscribe for or purchase securities.

Other than the Common Stock, there are

6

no other shares of any other class or series of capital stock of the Company issued or outstanding. The Company’s Certificate of Incorporation, as amended and as in effect on the date hereof (the “Certificate of Incorporation”), and the Company’s Bylaws, as amended and as in effect on the date hereof (the “Bylaws”), are included in the SEC Documents, and the Company shall not amend or otherwise modify the Certificate of Incorporation or Bylaws prior to the Closing. Except as disclosed in the SEC Documents, there are no voting agreements, buy-sell agreements, option or right of first purchase agreements or other agreements of any kind among the Company and any of the security holders of the Company relating to the securities of the Company held by them.

There are no legal, governmental or regulatory actions, suits, investigations, charges, claims, complaints, audits, inquiries or other proceedings pending or, to the Knowledge of the Company, threatened against the Company or any of its subsidiaries, before or by any court, regulatory body or administrative agency or any other governmental agency or body, domestic or foreign, which actions, suits or proceedings, individually or in the aggregate, could reasonably be expected to (a) challenge this Agreement or prohibit or delay the transactions contemplated herein or (b) have a Material Adverse Effect. Neither the Company nor any of its subsidiaries, is a party to or subject to the provisions of any injunction, judgment, decree or order of any court, regulatory body, administrative agency or other governmental agency or body that might have a Material Adverse Effect.

4.8 No Default or Consents. Neither the Company nor any of its subsidiaries, is in violation or default under its organizational documents. Neither the execution, delivery or performance of this Agreement or the Pre-Funded Warrant by the Company nor the consummation of any of the transactions contemplated hereby or thereby (including the issuance, sale and delivery by the Company of the Securities) will: (i) give rise to a right to terminate or accelerate the due date of any payment due under, or conflict with or result in the breach of any term or provision of, or constitute a default (or an event which with notice or lapse of time or both would constitute a default) under, or require any consent or waiver under, or result in the execution or imposition of any lien, charge or encumbrance upon any properties or assets of the Company or any subsidiary pursuant to the terms of, any indenture, mortgage, deed of trust or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which either or them or any of their respective properties or businesses are bound, or any franchise, license, permit, judgment, decree, order, statute, rule or regulation (including federal and state securities laws and regulations and the rules and regulations, assuming the correctness of the representations and warranties made by the Purchaser herein, of any self-regulatory organization to which the Company or any of its subsidiaries or their securities are subject) applicable to the Company, or (ii) violate or conflict with any provision of the Certificate of Incorporation or the Bylaws, except in the case of clause (i) as would not cause, either individually or in the aggregate, a Material Adverse Effect, and except for such consents or waivers which have already been obtained and are in full force and effect.

Since September 30, 2023, except as specifically disclosed in the SEC Documents, there have been no events, occurrences or developments that have had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect.

4.11 No Integrated Offering. None of the Company or any of its Affiliates, or any Person acting on its or their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of any of the Securities under the Securities Act or cause this offering of the Securities to be integrated with prior offerings by the Company for purposes of the Securities Act or any applicable stockholder approval provisions, including under the rules and regulations of the Trading Market.

4.12 Sarbanes-Oxley Act.

To the Knowledge of the Company, all material licenses or other material agreements under which the Company is granted rights to Intellectual Property Rights, if any, are in full force and effect and there is no material default by any other party thereto.

To the Knowledge of the Company, no event has occurred that, with notice or lapse of time or both, would constitute such a breach or default pursuant to any Material Contract by the Company, or, to the Knowledge of the Company, any other party thereto, and, as of the date of this Agreement, the Company has not received written notice of the foregoing or from the counterparty to any Material Contract (or, to the Knowledge of the Company, any of such counterparty’s Affiliates) regarding an intent to terminate, cancel, or modify any Material Contract (whether as a result of a change of control or otherwise).

The descriptions of the Studies contained in the SEC Documents are accurate in all material respects; to the Knowledge of the Company, there are no other preclinical studies and clinical trials, the results of which are inconsistent with or would call into question the results described in the SEC Documents in any material respect when viewed in the context in which such results are described and the stage of development of the Company’s product candidates; and neither the Company nor any of its subsidiaries has received any written notice or correspondence from the FDA or any other Regulatory Authority or institutional review board exercising comparable authority requiring or threatening the termination, suspension, or clinical hold of Studies, where such termination, suspension or clinical hold would reasonably be expected to have a Material Adverse Effect, and to the Knowledge of the Company, there are no reasonable grounds for the same.

4.18 Taxes. The Company and its subsidiaries have filed on a timely basis (giving effect to extensions) all required federal, state and foreign income and franchise tax returns (except where the failure to file would not, singly or in the aggregate, reasonably be expected to have a Material Adverse Effect on the Company and its subsidiaries) and have timely paid or accrued all taxes shown as due thereon (except for cases in which the failure to file or pay would not reasonably be expected to, singly or in the aggregate, have a Material Adverse Effect on the Company and its Subsidiaries, or, except as currently being contested in good faith and for which reserves required by U.S. GAAP have been created in the financial statements of the Company), including interest and penalties, and, to the Knowledge of the Company, there is no tax deficiency that has been or might be asserted or threatened against it or them that could have a Material Adverse Effect. All tax liabilities accrued through the date hereof have been adequately provided for on the books of the Company. There are no liens for material taxes upon the assets of the Company or any of its subsidiaries other than for current taxes not yet due and payable or for taxes that are being contested in good faith by appropriate proceedings and for which adequate reserves in accordance with GAAP has been made in the Company’s most recent financial statements included in the SEC Documents.

To the Knowledge of the Company, since the end of the Company’s most recent audited fiscal year, there has been no material weakness in the design or operation of the Company’s internal control over financial reporting (whether or not remediated) which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information.

No executive officer of the Company (as defined in Rule 501(f) promulgated under the Securities Act) has notified the Company that such officer intends to leave the Company or otherwise terminate such officer’s employment with the Company. To the Knowledge of the Company, no executive officer of the Company is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other agreement or any restrictive covenant involving or otherwise affecting such executive officer’s relationship with the Company, and the continued employment of each such executive officer does not subject the Company to any material liability with respect to any of the foregoing matters.

4.26 ERISA. The Company and its subsidiaries are in compliance in all material respects with all presently applicable provisions of the Employee Retirement Income Security Act of 1974, as amended, including the regulations and published interpretations thereunder (“ERISA”); no “reportable event” (as defined in ERISA) has occurred with respect to any “pension plan” (as defined in ERISA) for which the Company or any subsidiary would have any material liability; neither the Company nor any of its subsidiaries has not incurred or expects to incur material liability under (a) Title IV of ERISA with respect to termination of, or withdrawal from, any “pension plan” or (b) Sections 412 or 4971 of the Internal Revenue Code of 1986, as amended, including the regulations and published interpretations thereunder (the “Code”); and each “Pension Plan” for which the Company or any of its subsidiaries would have liability that is intended to be qualified under Section 401(a) of the Code is so qualified in all material respects and to the Knowledge of the Company, nothing has occurred, whether by action or by failure to act, which would cause the loss of such qualification.

4.28 Trading Market Compliance. Except as disclosed in the SEC Documents, the Company has not, in the previous twelve (12) months, received, nor is there any reasonable basis for, (i) written notice from the Trading Market that the Company is not in compliance with the listing or maintenance requirements of the Trading Market that would result in immediate delisting or (ii) any notification, Staff Delisting Determination, or Public Reprimand Letter (as such terms are defined in applicable listing rules of the Trading Market) that requires a public announcement by the Company of any noncompliance or deficiency with respect to such listing or maintenance requirements. Except as disclosed in the SEC Documents, the Company is in compliance with all listing and maintenance requirements of the Trading Market on the date hereof.

SECTION 5. REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PURCHASER.

The Purchaser represents and warrants to and covenants with the Company that:

5.1 Risk. The Purchaser, taking into account the personnel and resources it can practically bring to bear on the purchase of the Securities contemplated hereby, is knowledgeable, sophisticated and experienced in making, and is qualified to make, decisions with respect to investments in securities presenting an investment decision like that involved in the purchase of the Securities, including investments in securities issued by the Company, and has requested, received, reviewed and considered all information the Purchaser deems relevant (including the SEC Documents) in making an informed decision to purchase the Securities. The Purchaser (a) has conducted its own investigation of the Company and the Securities, (b) has had access to, and an adequate opportunity to review, financial and other information as it deems necessary to make its decision to purchase the Securities, (c) has been offered the opportunity to ask questions of the Company and received answers thereto, including on the financial information, as it deemed necessary in connection with its decision to purchase the Securities, and (d) has made its own assessment and has satisfied itself concerning the relevant tax and other economic considerations relevant to its investment in the Securities. The Purchaser has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of its prospective investment in the Securities; and has the ability to bear the economic risks of its prospective investment in the Securities and can afford the complete loss of such investment.

5.2 Purchase for Investment. The Purchaser is acquiring the Securities pursuant to this Agreement for its own account for investment only and with no present intention of distributing any of such Securities or any arrangement or understanding with any other Persons regarding the distribution of such Securities, except in compliance with Section 5.4.

5.3 Reliance. The Purchaser understands that the Securities are being offered and sold to it in reliance upon specific exemptions from the registration requirements of the Securities Act, the rules and regulations thereunder, and state securities laws and that the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the representations, warranties, agreements, acknowledgments and understandings of the Purchaser set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire the Securities. If any of the representations and warranties made by the Purchaser herein are no longer accurate in all material respects prior to Closing, the Purchaser shall promptly notify the Company. If the Purchaser is acquiring the Securities as a fiduciary or agent for one or more investor accounts, it represents that it has sole investment discretion with respect to each such account and it has full power to make the foregoing representations, acknowledgements and agreements on behalf of such account.

5.4 Compliance with the Securities Act. The Purchaser will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to buy, purchase or otherwise acquire or take a pledge of) any of the securities purchased hereunder except in compliance with the Securities Act, applicable blue sky laws, and the rules and regulations promulgated thereunder.

14

5.5 Accredited Investor. The Purchaser is (a) a qualified purchaser (as defined in Section 2(a)(51)(A) of the Investment Company Act of 1940, as amended), (b) a qualified institutional buyer (as defined in Rule 144A of the Securities Act), and/or (c) an accredited investor as described in Rule 501(a)(1), (2), (3) or (7) of the Securities Act. Accordingly, the Purchaser understands that the offering of the Securities meets the exemptions from filing under Financial Industry Regulatory Authority (“FINRA”) Rule 5123(b)(1)(B), (C) or (J).

5.6 Power and Authority. The Purchaser has all requisite corporate power, and has taken all requisite corporate action, to authorize, execute and deliver this Agreement and each of the other agreements and instruments contemplated herein to which the Purchaser is a party, to consummate the transactions contemplated herein and therein and to carry out and perform all of the Purchaser’s obligations hereunder and thereunder. Upon the execution and delivery of this Agreement, this Agreement shall constitute a valid and binding obligation of the Purchaser, enforceable in accordance with its terms, except (i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws relating to or affecting the enforcement of creditors’ rights generally and (ii) as limited by equitable principles generally, including any specific performance.

5.7 Broker Dealer. The Purchaser is not a broker or dealer registered pursuant to Section 15 of the Exchange Act.

5.8 Sophisticated Investor. The Purchaser (a) acknowledges that it is a sophisticated investor engaged in the business of assessing and assuming investment risks with respect to securities, including securities such as the Pre-Funded Warrant and Warrant Shares, and further acknowledges that the Company is entering into this Agreement in reliance on this acknowledgment, (b) is an institutional account as defined in FINRA Rule 4512(c), (c) is a sophisticated investor, experienced in investing in private equity transactions and capable of evaluating investment risks independently, both in general and with regard to all transactions and investment strategies involving a security or securities, and (d) has exercised independent judgment in evaluating our participation in the purchase of the Securities.

5.9 Other Securities Transactions. The Purchaser has not, either directly or indirectly through an Affiliate, agent or representative of the Company, engaged in any transaction in the securities of the Company other than with respect to the transactions contemplated herein, since the time that the Purchaser was first contacted by the Company or any other Person regarding the transactions contemplated hereby until the date hereof, except as set forth in filings made with the Commission pursuant to the Exchange Act. Notwithstanding the foregoing, (a) in the case of the Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of the Purchaser’s assets, the representation set forth above shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Securities covered by this Agreement and (b) in the case of the Purchaser that is affiliated with other funds or investment vehicles or whose investment advisor or sub-advisor that routinely acts on behalf of or pursuant to an understanding with the Purchaser is also an investment advisor or sub-advisor to other funds or investment vehicles, the representation set forth above shall only apply with respect to the personnel of such other funds or investment vehicles or such investment advisor or sub-advisor who had knowledge of the transactions contemplated hereby and not with respect to any personnel who have been effectively walled off by appropriate information barriers.

5.10 Independent Advice. The Purchaser understands that nothing in this Agreement or any other materials presented to the Purchaser by or on behalf of the Company in connection with the purchase and sale of the Securities constitutes legal, tax or investment advice. The Purchaser has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate in connection with its purchase of the Securities.

15

5.11 Legends. The Purchaser understands that, until such time as the Securities may be sold pursuant to an effective registration statement or Rule 144 under the Securities Act (“Rule 144”) (or any other applicable exemption from the registration requirements under the Securities Act), any certificates representing the Securities, whether maintained in a book entry system or otherwise, will bear one or more legends in substantially the following form and substance:

“THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), OR ANY OTHER APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, HYPOTHECATED OR OTHERWISE DISPOSED OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO A TRANSACTION WHICH IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION, IN EACH CASE IN ACCORDANCE WITH ALL APPLICABLE SECURITIES LAWS, AND, IN THE CASE OF A TRANSACTION EXEMPT FROM, OR NOT SUBJECT TO, SUCH REGISTRATION, THE HOLDER WILL NOTIFY ANY SUBSEQUENT PURCHASER OF THE SECURITIES EVIDENCED BY THIS CERTIFICATE FROM IT OF SUCH RESALE RESTRICTIONS.”

In addition, any stock certificates, whether maintained in a book entry system or otherwise, representing the Securities may contain any legend required by the blue sky laws of any state to the extent such laws are applicable to the sale of such Securities hereunder. The Company shall promptly help facilitate the removal of such legend as soon as it is legally permitted to do so under Rule 144, or to facilitate any transfer of the Securities under Rule 144 that may be requested by the Purchaser, but shall not be obligated to incur any material, noncustomary costs or expenses in taking such actions other than as set forth herein.

5.12 Restricted Securities. The Purchaser understands that the Securities are characterized as “restricted securities” under the federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and that under such laws and applicable regulations such Securities may be resold without registration under the Securities Act only in certain limited circumstances. Accordingly, the Purchaser represents that it is familiar with Rule 144 of the Securities Act, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

5.13 Beneficial Ownership. The purchase by the Purchaser of the Securities issuable to it at the Closing will not result in the Purchaser (individually or together with any other Person with whom the Purchaser has identified, or will have identified, itself as part of a “group” in a public filing made with the Commission involving the Company’s securities, where such aggregation would be made according to Section 13(d) of the Exchange Act) acquiring, or obtaining the right to acquire, in excess of 19.999% of the outstanding shares of Common Stock or the voting power of the Company on a post-transaction basis that assumes that such Closing shall have occurred. The Purchaser does not presently intend to, alone or together with others, make a public filing with the Commission to disclose that it has (or that it together with such other Persons have) acquired, or obtained the right to acquire, as a result of such Closing (when added to any other securities of the Company that it or they then own or have the right to acquire), in excess of 19.999% of the outstanding shares of Common Stock or the voting power of the Company on a post-transaction basis that assumes that each Closing shall have occurred (including assuming the effectiveness of any “blocker” or similar limitations on beneficial ownership contained in the applicable documentation for the Securities).

16

SECTION 6. REGISTRATION OF THE SECURITIES AND COMPLIANCE WITH THE SECURITIES ACT.

6.1 Registration Procedures and Expenses.

(a) Secondary Registration Statement. The Company shall prepare and file, on or before the date that is ninety (90) days after the Closing (the “Filing Deadline”), with the Commission a Registration Statement on Form S-3 (except if the Company is not then eligible to use Form S-3, in which case such registration shall be on Form S-1) to register for resale the Warrant Shares (together with any shares of capital stock issued or issuable, from time to time, upon any reclassification, share combination, share subdivision, stock split, share dividend or similar transaction or event or otherwise as a distribution on, in exchange for or with respect to any of the foregoing, in each case held at the relevant time by the Purchaser, the “Registrable Securities”), as appropriate (the “Secondary Registration Statement”), relating to and providing for the resale of the Warrant Shares by the Purchaser on a continuous basis pursuant to Rule 415 under the Securities Act or, if Rule 415 is not available for offers and sales of the Registrable Securities, by such other means of distribution of Registrable Securities as the Purchaser may reasonably specify. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the Registrable Securities on the Secondary Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Registrable Securities (and notwithstanding that the Company used diligent efforts to advocate with the staff of the Commission for the registration of all or a greater portion of the Registrable Securities), the Secondary Registration Statement shall register for resale such number of Registrable Securities that is equal to the maximum number of Registrable Securities as is permitted by the Commission. In such event, the number of Registrable Securities for which resale is to be registered for each selling shareholder named in the Secondary Registration Statement shall be reduced pro rata among all such selling shareholders and as promptly as practicable after being permitted to register additional Registrable Securities under Rule 415 under the Securities Act, the Company amend the Secondary Registration Statement or file one or more new registration statement(s) (such amendment or new registration statement, a “Remainder Registration Statement”) to register such additional Registrable Securities not included in the Secondary Registration Statement and cause such Remainder Registration Statement to become effective as promptly as practicable after the filing thereof, but in any event no later than thirty (30) calendar days after the filing of such Remainder Registration Statement (the “Remainder Effectiveness Deadline”); provided, that the Remainder Effectiveness Deadline shall be extended to sixty (60) calendar days after the filing of such Remainder Registration Statement if the SEC notifies the Company that it will “review” such Remainder Registration Statement; provided, further, notwithstanding the foregoing, that the Company shall use reasonable best efforts to have such Remainder Registration Statement declared effective within five (5) business days after the date the Company is notified orally or in writing (whichever is earlier) by the Commission that such Remainder Registration Statement will not be reviewed or will not be subject to further review. Any failure by the Company to file the Secondary Registration Statement by the Filing Deadline or to effect the Secondary Registration Statement by the Effectiveness Deadline or the Remainder Registration Statement by the Remainder Effectiveness Deadline shall not otherwise relieve the Company of its obligations to file or effect the Secondary Registration Statement or Remainder Registration Statement set forth in this Section 6.1(a).

(b) The Company shall use its reasonable best efforts, subject to receipt of necessary information from the Purchaser, to cause the Commission to declare a Secondary Registration Statement covering the Warrant Shares effective as soon as practicable after the date of the filing thereof and in any event no later than the earlier of (i) thirty (30) days after such filing and (ii) the fifth (5th) Business Day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Secondary Registration Statement will not be reviewed or will not be subject to further review (in either case, such date, the “Effectiveness Deadline”); provided, that the Effectiveness Deadline shall be extended to sixty (60) calendar days after the filing of such Secondary Registration Statement if the SEC notifies the Company that it will “review” such Secondary Registration Statement.

17

(c) The Company shall promptly prepare and file with the Commission such amendments and supplements to the Secondary Registration Statement and the prospectus used in connection therewith as may be necessary to keep the Secondary Registration Statement effective until the earliest of (i) such time as all of the Warrant Shares purchased by the Purchaser pursuant to the terms of this Agreement have been sold pursuant to the Secondary Registration Statement, or (ii) such time as the Warrant Shares become eligible for resale by non-Affiliates without any volume limitations or other restrictions pursuant to Rule 144(b)(1)(i) or any other rule of similar effect.

(d) Upon notification by the Commission that the Secondary Registration Statement will not be reviewed or is not subject to further review by the Commission, the Company shall within five (5) Business Days following the date of such notification request acceleration of such Secondary Registration Statement (with the requested effectiveness date to be not more than two Business Days later).

(e) The Company shall furnish to the Purchaser with respect to the Warrant Shares registered under any Secondary Registration Statement (and to each underwriter, if any, of such Warrant Shares) such number of copies of prospectuses and such other documents as the Purchaser may reasonably request, in order to facilitate the public sale or other disposition of all or any of the Warrant Shares by the Purchaser.

(f) The Company shall bear all expenses in connection with the procedures in paragraphs (a) through (e) of this Section 6.1 and the registration of the Warrant Shares pursuant to the Secondary Registration Statement, other than fees and expenses, if any, of counsel or other advisers to the Purchaser or underwriting discounts, brokerage fees and commissions incurred by the Purchaser, if any in connection with the offering of the Warrant Shares pursuant to the Secondary Registration Statement.

(g) In order to enable the Purchaser to sell the Warrant Shares under Rule 144, the Company shall use its reasonable best efforts to comply with the requirements of Rule 144, including without limitation, use its reasonable best efforts to comply with the requirements of Rule 144(c)(1) with respect to public information about the Company and to timely file all reports required to be filed by the Company under the Exchange Act.

(h) The Company shall provide the Purchaser a reasonable opportunity to review and comment on all disclosures regarding the Purchaser and any plan of distribution proposed by them in connection with the preparation of any Secondary Registration Statement not less than five (5) Business Days prior to the filing of such Secondary Registration Statement. Notwithstanding anything to the contrary contained herein, in no event shall the Company be permitted to name the Purchaser or Affiliate of the Purchaser as an “underwriter” without the prior written consent of the Purchaser; provided, that if the Commission requires that the Purchaser be identified as a statutory underwriter in either the Secondary Registration Statement or a Remainder Registration Statement, the Purchaser will have the option, in its sole and absolute discretion, to either (i) have the opportunity to withdraw from the Secondary Registration Statement or Remainder Registration Statement, as the case may be, upon its prompt written request to the Company or (ii) be included as such in the Secondary Registration Statement or Remainder Registration Statement, as the case may be.

6.2 Restrictions on Transfer. The Purchaser agrees that it will not effect any disposition of the Securities that would constitute a sale within the meaning of the Securities Act or pursuant to any applicable state securities laws, unless and until (1) there is then in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement or (2) such disposition is otherwise permitted by law, including pursuant to the procedures set forth in Rule 144 or any other applicable exemption from the registration requirements under the Securities Act.

6.3 Indemnification. For the purpose of this Section 6.3: (i) the term “Purchaser/Affiliate” shall mean any affiliate of the Purchaser, including, without limitation, any general partner or managing member of the Purchaser, any investment adviser of the Purchaser, or any transferee who is an affiliate of the Purchaser, and any person who controls the Purchaser or any affiliate of the Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act; and (ii) the term “Registration Statement” shall include any preliminary prospectus, final prospectus (the “Prospectus”), free writing prospectus, exhibit, supplement or amendment included in or relating to, and any document incorporated by reference in, the Secondary Registration Statement referred to in Section 6.1.

(a) The Company agrees to indemnify and hold harmless the Purchaser and the Purchaser/Affiliate, against any losses, claims, damages, liabilities or expenses, joint or several, that the Purchaser or Purchaser/Affiliate incurs, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of the Company, such consent not to be unreasonably withheld or delayed), insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) (i) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, including the Prospectus, financial statements and schedules, and all other documents filed as a part thereof or incorporated by reference therein, as amended at the time of effectiveness of the Registration Statement, including any information deemed to be a part thereof as of the time of effectiveness pursuant to paragraph (b) of Rule 430A under the Securities Act, or pursuant to Rules 430B, 430C or 434 under the Securities Act, or the Prospectus, in the form first filed with the Commission pursuant to Rule 424(b) under the Securities Act, or filed as part of the Registration Statement at the time of effectiveness if no Rule 424(b) filing is required or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state in any of them a material fact required to be stated therein or necessary to make the statements in the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in light of the circumstances under which they were made, (ii) any violation or alleged violation by the Company or its agents of the Securities Act, the Exchange Act, or any other federal or state securities law or any rule or regulation thereunder, in connection with the performance or non-performance of its obligations under this Agreement or any action or inaction required of the Company in connection with any registration or (iii) arise out of or are based in whole or in part on any inaccuracy in the representations or warranties of the Company contained in this Agreement, breach of any covenant of the Company contained in this Agreement or any failure of the Company to perform its other obligations hereunder or under law, and will promptly reimburse the Purchaser and the Purchaser/Affiliate for any legal and other out-of-pocket expenses as such expenses are reasonably incurred and documented by the Purchaser or the Purchaser/Affiliate in connection with investigating, defending or preparing to defend, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that the Company will not be liable for amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of the Company, which consent shall not be unreasonably withheld, conditioned, or delayed, and the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein, or (ii) the inaccuracy of any representation or warranty made by the Purchaser herein, (iii) any statement or omission in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Purchaser prior to the pertinent sale or sales by the Purchaser.

19

(b) The Purchaser will indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages, liabilities or expenses that the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person reasonably incurs, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, but only if such settlement is effected with the written consent of the Purchaser, such consent not to be unreasonably withheld or delayed) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements in the Registration Statement or any amendment or supplement thereto not misleading or in the Prospectus or any amendment or supplement thereto not misleading in the light of the circumstances under which they were made, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use therein; and will reimburse the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person for any legal and other expense reasonably incurred by the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action; provided, however, that (i) the Purchaser’s aggregate liability under this Section 6 shall not exceed the amount of net proceeds received by the Purchaser on the sale of the Registrable Securities pursuant to the Registration Statement giving rise to such indemnification obligation, and (ii) the Purchaser will not be liable for amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the written consent of the Purchaser.

(c) Promptly after receipt by an indemnified party under this Section 6.3 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 6.3 promptly notify the indemnifying party in writing thereof, but the omission to notify the indemnifying party will not relieve it from any liability that it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 6.3 to the extent it is not prejudiced as a result of such failure. In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party, and the indemnifying party and the indemnified party shall have reasonably concluded, based on an opinion of counsel reasonably satisfactory to the indemnifying party, that there may be a conflict of interest between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 6.3 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless (i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not

20

be liable for the expenses of more than one separate counsel, reasonably satisfactory to such indemnifying party, representing all of the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. In no event shall any indemnifying party be liable in respect of any amounts paid in settlement of any action unless the indemnifying party shall have approved in writing the terms of such settlement; provided that such approval shall not be unreasonably withheld or delayed. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of or consent to the entry of any judgment in any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnification could have been sought hereunder by such indemnified party, unless such settlement or judgment (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding, (y) imposes no liability or obligation on the indemnified person and (z) does not include any admission of fault, culpability, wrongdoing or malfeasance by or on behalf of the indemnified person. The indemnifying party shall notify the indemnified party promptly of the institution, threat or assertion of any proceeding in connection with, arising out of, as a result of, relating to or based upon the transactions contemplated by this Agreement of which the indemnifying party is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such indemnified party and shall survive the transfer of any of the Securities by any of the Purchaser as permitted by this Agreement. Subject to the terms of this Agreement, all reasonable and documented fees and expenses of the indemnified party (including reasonable and documented fees and expenses to the extent incurred in connection with investigating or preparing to defend such proceeding in a manner not inconsistent with this Section 6.3) shall be paid to such indemnified party, as incurred, within ten (10) Business Days of written notice thereof to the indemnifying party, provided that the indemnified party shall promptly reimburse the indemnifying party for that portion of such fees and expenses applicable to such actions for which such indemnified party is finally judicially determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) not to be entitled to indemnification hereunder.

(d) If the indemnification provided for in this Section 6.3 is required by its terms but is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party under paragraphs (a), (b) or (c) of this Section 6.3 in respect to any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to herein (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Purchaser from the private placement of Securities hereunder or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but the relative fault of the Company and the Purchaser in connection with the statements or omissions or inaccuracies in the representations and warranties in this Agreement and/or the Registration Statement that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Purchaser on the other shall be deemed to be in the same proportion as the amount paid by the Purchaser to the Company pursuant to this Agreement for the Securities purchased by the Purchaser that were sold pursuant to the Registration Statement bears to the difference (the “Difference”) between the amount the Purchaser paid for the Securities that were sold pursuant to the Registration Statement and the amount received by the Purchaser from such sale. The relative fault of the Company on the one hand and the Purchaser on the other shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or alleged omission to state a material fact or the inaccurate or the alleged inaccurate representation and/or warranty relates to information supplied by the Company or by the Purchaser and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or

21

payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in paragraph (c) of this Section 6.3, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in paragraph (c) of this Section 6.3 with respect to the notice of the threat or commencement of any threat or action shall apply if a claim for contribution is to be made under this paragraph (d); provided, however, that no additional notice shall be required with respect to any threat or action for which notice has been given under paragraph (c) for purposes of indemnification. The Company and the Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 6.3 were determined solely by pro rata allocation (even if the Purchaser were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this paragraph. Notwithstanding the provisions of this Section 6.3, (i) no Purchaser shall be required to contribute any amount in excess of the amount by which the Difference exceeds the amount of any damages that the Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission and (ii) the Purchaser’s aggregate liability under this Section 6.3 shall not exceed the amount of net proceeds received by the Purchaser on the sale of the Registrable Securities pursuant to the Registration Statement giving rise to such indemnification or contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

6.4 Information Available. The Company, upon the reasonable request of the Purchaser, shall make available for inspection by the Purchaser, any deemed underwriter participating in any disposition pursuant to the Secondary Registration Statement and any attorney, accountant or other agent retained by the Purchaser or any deemed underwriter, all financial and other records, pertinent corporate documents and properties of the Company.

6.5 Delay in Filing or Effectiveness of Secondary Registration Statement. If a Secondary Registration Statement covering the Warrant Shares is not filed on or prior to the Filing Deadline or is not declared effective by the Commission on or prior to the Effectiveness Deadline, then for each day following the Filing Deadline or Effectiveness Deadline, as applicable, until but excluding the date the Company files or the Commission declares the Secondary Registration Statement effective, as the case may be, the Company shall, for each such day, pay the Purchaser with respect to any such failure, as liquidated damages and not as a penalty, an amount per thirty (30)-day period equal to 1.0% of the purchase price paid by the Purchaser for its Shares and Warrant Shares pursuant to this Agreement (calculated on a daily pro rata basis for any portion of such thirty (30)-day period prior to the cure of such failure); and for any such thirty (30)-day period (or earlier period if such failure is cured prior to thirty (30) days), such payment shall be made no later than three (3) Business Days following such thirty (30)-day period (or earlier period if such failure is cured prior to thirty (30) days). Notwithstanding the foregoing provisions, in no event shall the amount of Liquidated Damages payable by the Company to the Purchaser pursuant to this Section 6.5 exceed, in the aggregate, five percent (5.0%) of the aggregate purchase price paid by the Purchaser pursuant to this Agreement. Such payments shall be made to the Purchaser in cash.

SECTION 7. NO BROKER’S FEE.

Each of the Company and the Purchaser (on a several but not joint basis) hereby represents that no broker, investment banker, financial advisor or other individual, corporation, general or limited partnership, limited liability company, firm, joint venture, association, enterprise, joint securities company, trust, unincorporated organization or other entity is entitled to any broker’s, finder’s, financial advisor’s or other similar fee or commission in connection with the transactions contemplated by this Agreement. Each party hereto further agrees to indemnify each other party for any claims, losses or expenses incurred by such other party as a result of the representation in this Section 7 being untrue.

22

SECTION 8. COVENANTS.

8.1 Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D of the Securities Act. The Company will take such action as the Company shall reasonably determine is necessary in order to obtain an exemption from, or to qualify the Securities for, sale to the Purchaser at the Closing pursuant to this Agreement under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon the written request of the Purchaser.

8.2 Transfer Taxes. On the Closing Date, all stock transfer or other taxes (other than income taxes) that are required to be paid in connection with the issuance, sale and delivery of the Securities to the Purchaser hereunder will be fully paid or provided for by the Company and all laws imposing such taxes will have been fully complied with and the Purchaser and its Affiliates shall have no obligation therefor.

8.3 Listing of Common Stock. The Company shall promptly secure the listing of the Warrant Shares upon the Trading Market and each other national securities exchange and automated quotation system that requires an application by the Company for listing, if any, upon which shares of Common Stock are then listed (subject to official notice of issuance) and shall maintain such listing, so long as any other shares of Common Stock shall be so listed. The Company shall use its reasonable best efforts to maintain the Common Stock’s listing on the Trading Market. The Company shall pay all fees and expenses in connection with satisfying its obligations under this Section 8.3.

8.4 Reservation of Common Stock. As of the date hereof, the Company has reserved and the Company shall continue to reserve and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue the Warrant Shares that are issuable upon the exercise of the Pre-Funded Warrant.

8.5 [Reserved].

8.6 Adjustments in Share Numbers and Prices. In the event of any stock split, subdivision, dividend or distribution payable in shares of Common Stock (or other securities or rights convertible into, or entitling the holder thereof to receive directly or indirectly shares of Common Stock), combination or other similar recapitalization or event occurring after the date hereof and prior to the Closing, each reference this Agreement to a number of shares or a price per share shall be deemed to be amended to appropriately account for such event.

8.7 Legend Removal. The Company shall, at its sole expense, upon appropriate notice from the Purchaser stating that Registrable Securities have been sold pursuant to an effective Secondary Registration Statement, under Rule 144, or any other exemption from the registration requirements under the Securities Act, within two (2) Trading Days of such notice, cause its transfer agent to timely prepare and deliver certificates or book-entry shares representing the Warrant Shares to be delivered to a transferee pursuant to such sale, which certificates or book-entry shares shall be free of any restrictive legends and in such denominations and registered in such names as the Purchaser may request. Further, the Company shall, at its sole expense, cause its legal counsel or other counsel satisfactory to the transfer agent to provide opinions as may reasonably be required by the transfer agent in connection with the removal of legends, subject to the requirements under the Securities Act and the rules and regulations promulgated thereunder. The Purchaser may request that the Company remove, and the Company agrees to authorize the removal of, any legend from such Securities, following the delivery by the Purchaser to the Company or the Company’s transfer agent of either a legended certificate representing such Securities or, if the Securities are issued in book-entry form, a written request for legend removal: (i) following any sale of such Securities pursuant to

23

Rule 144 or any other applicable exemption from the registration requirements under the Securities Act, (ii) if such Securities are eligible for sale under Rule 144(b)(1), or (iii) following the time that the Secondary Registration Statement is declared effective. If a legend removal request is made pursuant to the foregoing, the Company will, no later than two (2) Trading Days following the delivery by the Purchaser to the Company or the Company’s transfer agent of a legended certificate representing such Securities (or a request for legend removal, in the case of Securities issued in book-entry form), deliver or cause to be delivered to the Purchaser a certificate representing such Securities that is free from all restrictive legends or an equivalent book-entry position, as requested by the Purchaser. Certificates for Securities free from all restrictive legends may be transmitted by the Company’s transfer agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company (“DTC”) as directed by the Purchaser. The Company warrants that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in this Agreement. If the Purchaser effects a transfer of the Securities in accordance with Section 5.11, the Company shall permit the transfer and shall promptly instruct its transfer agent to issue one or more certificates or credit shares to the applicable balance accounts at DTC in such name and in such denominations as specified by the Purchaser to effect such transfer. The Purchaser hereby agrees that the removal of the restrictive legend pursuant to this Section 8.7 is predicated upon the Company’s reliance that the Purchaser will sell any such Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and the Purchaser shall deliver a certificate reasonably satisfactory to the Company to the foregoing effect. Prior to the Company and its transfer agent agreeing to a form of representation letter to be given in connection with any legend removal opinion, the Company shall allow each Purchaser to review such form and shall cooperate, reasonably and in good faith, and accept reasonable comments thereto from the Purchasers.

10.1 Waivers and Amendments. Neither this Agreement nor any provision hereof may be changed, waived, discharged, terminated, modified or amended except upon the written consent of the Company and the Purchaser. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing wavier in the future or a waiver of any subsequent default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. The failure of any party at any time to require another party’s performance of any obligation under this Agreement shall not affect the right subsequently to require performance of that obligation.

10.2 Headings; Interpretation. The headings of the various sections of this Agreement have been inserted for convenience of reference only and shall not be deemed to be part of this Agreement. The terms “hereof,” “herein,” “hereby” and derivative or similar words refer to this Agreement as a whole and not to any particular provision of this Agreement. Except when used together with the word “either” or otherwise for the purpose of identifying mutually exclusive alternatives, the term “or” has the inclusive meaning represented by the phrase “and/or.” All references in this Agreement to “dollars” or “$” shall mean United States dollars. Except where the context otherwise requires, wherever used the singular shall include the plural, the plural the singular, the use of any gender shall be applicable to all genders. The term “including” or “includes” means “including without limitation” or “includes without limitation.”

10.3 Severability. In case any provision contained in this Agreement should be invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby.

10.4 Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Securities. The agreements and covenants contained herein shall survive for the applicable statute of limitations.

10.5 Governing Law; Jurisdiction. This Agreement shall be governed by and interpreted in accordance with the substantive laws of the State of New York, without regard to its or any other jurisdiction’s choice of law rules. Any and all disputes arising out of, concerning, or related to this Agreement, or to the interpretation, performance, breach or termination thereof shall be referred to and resolved by the federal courts located in New York, New York or, to the extent no such court does not have subject matter jurisdiction, the state courts of the State of New York located in New York, New York (the

25

“Specified Courts”). Each of the parties hereto irrevocably and unconditionally submits to the exclusive jurisdiction of the Specified Courts, waives any objection to the laying of venue of any suit, action or proceeding brought in such courts and waives any claim that any such suit, action or proceeding brought in any such court has been brought in an inconvenient forum. EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, THE OTHER TRANSACTION DOCUMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT CLAIMS, TORT CLAIMS (INCLUDING NEGLIGENCE), BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL.

10.6 Counterparts. This Agreement may be executed in counterparts, each of which shall constitute an original, but all of which, when taken together, shall constitute but one instrument, and shall become effective when one or more counterparts have been signed by each party hereto and delivered to the other party. Signatures to this Agreement transmitted by facsimile, by email in “portable document format” (“.pdf”), or by any other electronic means intended to preserve the original graphic and pictorial appearance of this Agreement shall have the same effect as physical delivery of the paper document bearing original signature.

10.7 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto. The Purchaser may not assign this Agreement or any rights or obligations hereunder, in whole or in part, without the prior written consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed; provided, however, that the Purchaser may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to a third party acquiring some or all of the Securities in a transaction complying with applicable securities laws without the prior written consent of the Company, provided such assignee agrees in writing to be bound by the provisions hereof that apply to the Purchaser. The Company may not assign this Agreement or any rights or obligations hereunder, in whole or in part, without the prior written consent of the Purchaser. Without limiting the generality of the foregoing, in the event that the Company is a party to a merger, consolidation, share exchange or similar business combination transaction in which the Common Stock is converted into the equity securities of another Person, from and after the effective time of such transaction, such Person shall, by virtue of such transaction, be deemed to have assumed the obligations of the Company hereunder, the term “Company” shall be deemed to refer to such Person and the term “Pre-Funded Warrant”, or “Warrant Shares” shall be deemed to refer to the securities received by the Purchaser in exchange therefor in connection with such transaction. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective permitted successors and assigns any rights, remedies, obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.

10.8 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 6.3 and this Section 10.8.

26

10.9 Entire Agreement. This Agreement and the other documents and instruments delivered pursuant hereto or thereto, including the exhibits and schedules hereto or thereto, constitute the full and entire understanding and agreement between the parties hereto with regard to the subjects hereof and thereof and supersede all prior agreements and understandings, both oral and written, between the parties with respect to the subject matter hereof and thereof, provided, that any confidentiality agreement that the Company and the Purchaser may have entered into in contemplation of potentially entering into this Agreement, shall survive in accordance with its terms and provisions.

10.10 Payment of Fees and Expenses. Except as otherwise provided herein or in the other documents or instruments contemplated hereby, each of the Company and the Purchaser shall bear its own expenses and legal fees incurred on its behalf with respect to this Agreement and the transactions contemplated hereby.

10.11 Further Actions. Each party hereto agrees to execute, acknowledge, and deliver such further instruments, and to do all such other acts, as may be reasonably necessary or appropriate in order to carry out the purposes and intent of this Agreement.

10.12 Securities Law Disclosure. By no later than 9:00 A.M., New York City time, on the Trading Day immediately following the Effective Date (provided that, if this Agreement is executed between midnight and 9:00 A.M., New York City time on any Trading Day, no later than 9:01 A.M. on the Effective Date), the Company shall issue a press release and/or file a Current Report on Form 8-K with the Commission (the “Disclosure Document”) disclosing all material terms of the transactions contemplated by this Agreement; provided, that the Purchaser shall be given a reasonable opportunity to review and comment on the disclosure contained in the Disclosure Document prior to issuance or filing). In addition, unless it has already done so by filing the Disclosure Document, on or before the fourth (4^th) Business Day following the Effective Date, the Company shall file a Current Report on Form 8-K with the Commission disclosing all material terms of the transactions contemplated by this Agreement. From and after the issuance of the Disclosure Document, no Purchaser shall be in possession of any material non-public information received from the Company or from any other representative of the Company in connection with the transactions contemplated by this Agreement. Except for the Disclosure Document and the Current Report on Form 8-K contemplated by this Section 10.12, all public announcements regarding this Agreement shall be issued only in accordance with Section 10.14.

10.13 Termination. This Agreement (i) shall be terminated at any time prior to Closing automatically if the Closing has not been consummated on or prior to the fifth Business Day from the Effective Date, or (ii) may be terminated by the Purchaser if any of the conditions set forth in Section 3.2(a) or Section 3.2(b) shall have become incapable of fulfillment, and shall not have been waived by the Purchaser, provided, however, that no such termination will affect the right of any party to sue for any breach by the other party (or parties), and, upon such termination pursuant to this Section 10.14, any purchase price wired to the Company by the Purchaser shall be promptly returned to the Purchaser, but in no event later than the first Trading Day following such termination.

10.14 Public Announcement. The Company shall not publicly disclose the name of the Purchaser, or include the name of the Purchaser or an Affiliate of the Purchaser without the prior written consent of the Purchaser (i) in any press release or marketing materials or (ii) in any filing with the Commission or any regulatory agency or Trading Market, except as required by U.S. federal securities law (A) in connection with any Secondary Registration Statement contemplated by this Agreement and (B) to the extent such disclosure is required by law, request of the Commission’s staff or Trading Market regulations, in which case the Company shall provide the Purchaser with prior written notice of and an opportunity to review such disclosure permitted under this subclause (ii).
