	Warrant Shares:                     	 	Issue Date: June     , 2009

 THIS SERIES 4 COMMON STOCK PURCHASE WARRANT
(the “Warrant”) certifies that, for value received,                      (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 December 1, 2009 (the “Initial Exercise Date”) and on or prior to the close of business on the 181st day following the Initial Exercise Date (the “Termination Date”) but not thereafter, to subscribe for and purchase from Hecla Mining Company,
a Delaware corporation (the “Company”), up to              shares (the “Warrant Shares”) of Common Stock; provided, however, in the event
that there is a Public Information Failure after December 1, 2009, for each Trading Day that such failure occurs the Termination Date shall be extended by one additional Trading Day. 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). 
 Section 1. Definitions. Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in that certain Securities Purchase Agreement (the “Purchase Agreement”), dated June 2, 2009, among the Company and the purchasers signatory thereto.

 Section 2. Exercise. 
 a) Exercise of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, but not as to fractional shares of Common Stock, at any time or times on or after the
Initial Exercise Date and on or before the 

  

 1 

 
Termination Date by delivery to the principal executive office of the Company (or such other office or agency of the Company as it may designate by notice in
writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise Form annexed hereto; and, within 3 Trading Days of the date said Notice of Exercise is
delivered to the Company, the Company shall have received payment of the aggregate Exercise Price of the shares thereby purchased by wire transfer or cashier’s check drawn on a United States bank or, if available, pursuant to the cashless
exercise procedure specified in Section 2(c) below. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company 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 3 Trading Days of the date the final Notice of Exercise is delivered to the Company.
Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant Shares available hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to
the applicable number of Warrant Shares purchased. 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
Form within 2 Business 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 exercise price per share of the Common Stock under this Warrant shall be $3.68, subject to adjustment hereunder (the “Exercise Price”). Notwithstanding anything
herein to the contrary, in no event shall the Exercise Price be adjusted to below the per share par value of the Company’s Common Stock. 
 c) Cashless Exercise. If at any time after the six (6) month anniversary of the date this Warrant was issued to the Holder, there is no effective Registration Statement registering, or no current
prospectus available for, the resale of the Warrant Shares by the Holder, then 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
certificate for the number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: 
  

			
	(A) =	 	the VWAP on the Trading Day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise,” as set forth in the applicable Notice of
Exercise;
		
	(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.

  

 2 

 d) Holder’s Restrictions. 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 other person or entity acting as a group together with the Holder or any of the Holder’s Affiliates), 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 Affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall
exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates and (B) exercise or conversion of the
unexercised or nonconverted portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein
beneficially owned by the Holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this Section 2(d), 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. To the extent that the limitation contained in this Section 2(d) applies, the determination of whether this Warrant is exercisable (in relation to other securities
owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of
whether this Warrant is exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company
shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules
and regulations promulgated thereunder. For purposes of this Section 2(d), 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 report on Form 10-K or Form 10-Q, as applicable, (B) a more recent public announcement by the Company or (C) any other notice by the Company or the Transfer Agent setting forth the number of shares of
Common Stock outstanding. Upon the written or oral request of a Holder, the Company shall within two Trading Days 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 its Affiliates since the date as of which such number of outstanding
shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable
upon exercise of this Warrant. The Holder, upon not less than 

  

 3 

 
61 days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 2(d), provided that
the Beneficial Ownership Limitation in no event exceeds 9.99% 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(d) shall continue to apply. Any such increase will not be effective until the 61st day after such notice is
delivered to the Company. The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(d) to correct this paragraph (or any portion hereof) which may be
defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply
to a successor holder of this Warrant. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of holders of a majority of its Common Stock. 
 e) Mechanics of Exercise. 
 i. Delivery of Certificates Upon Exercise. Certificates for shares purchased hereunder shall be transmitted by the Transfer Agent to the Holder by crediting the account of the Holder’s prime broker with
the Depository Trust Company through its Deposit Withdrawal Agent Commission (“DWAC”) system 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 shares are eligible for resale by the Holder without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the
address specified by the Holder in the Notice of Exercise within 3 Trading Days from the delivery to the Company of the Notice of Exercise Form, surrender of this Warrant (if required), and payment of the aggregate Exercise Price as set forth above
(including by cashless exercise, if permitted)(such date, the “Warrant Share Delivery Date”). This Warrant shall be deemed to have been exercised on the date the Exercise Price is received by the Company. The Warrant Shares shall be
deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such shares for all purposes, as of the date the Warrant has been exercised by payment to the Company
of the Exercise Price (or by cashless exercise, if permitted) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(e)(vi) prior to the issuance of such shares, have been paid. 
 ii. Delivery of New Warrants Upon Exercise. If this Warrant shall have been exercised in part and shall not have expired, the
Company shall, at the request of the Holder and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant Shares, deliver to Holder a new Warrant evidencing 

  

 4 

 
the rights of Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in all other respects be identical with
this Warrant. 
 iii. Rescission Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder a
certificate or the certificates representing the Warrant Shares pursuant to Section 2(e)(i) by the Warrant Share Delivery Date, then the Holder will have the right to rescind such exercise. 
 iv. Compensation for Buy-In on Failure to Timely Deliver Certificates Upon Exercise. In addition to any other rights available to
the Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing the Warrant Shares pursuant to a proper exercise on or before the second Trading Day following the Warrant Share
Delivery Date, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale
by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount by which (x) the Holder’s total purchase
price (including brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Warrant Shares that the Company was required to deliver to the Holder in
connection with the exercise at issue times (2) the price per share at which the sell order giving rise to such purchase obligation was executed, and (B) at the option of the Holder, either reinstate the portion of the Warrant and
equivalent number of Warrant Shares for which such exercise was not honored or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations
hereunder against payment of the Exercise Price. For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale
price giving rise to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts
payable to the Holder in respect of the Buy-In and evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a
decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates representing shares of Common Stock upon exercise of the Warrant as required pursuant to the terms hereof. 

v. No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the
exercise of this 

  

 5 

 
Warrant. As to any fraction of a share which 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. 
 vi. Charges, Taxes and Expenses. Issuance of certificates for 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 certificate, all of which taxes and expenses shall be paid by the Company, and such certificates shall be issued in the name of the Holder or in such name or names
as may be directed by the Holder; provided, however, that in the event certificates for 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 may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto. 
 vii. 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. 
 Section 3. Certain Adjustments. 
 a) Stock Dividends and Splits. If the Company, at any time 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 or by the terms of any preferred stock which is outstanding on the issuance date hereof), (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 record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the
effective date in the case of a subdivision, combination or re-classification. 
 b) [RESERVED]. 
  

 6 

 c) [RESERVED]. 
 d) Fundamental Transaction. If, at any time while this Warrant is outstanding, (i) the Company, 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, (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, (v) the Company, directly or indirectly, in one or more
related transactions consummates a stock or share purchase agreement or other business combination (including, without limitation, a reorganization, recapitalization, spin-off or scheme of arrangement) with another Person whereby such other Person
acquires more than 50% of the outstanding shares of Common Stock (not including any shares of Common Stock held by the other Person or other Persons making or party to, or associated or affiliated with the other Persons making or party to, such
stock or share purchase agreement or other business combination) (each a “Fundamental Transaction”), then, upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant Share that would
have been issuable upon such exercise immediately prior to the occurrence of such Fundamental Transaction (without regard to any limitation in Section 2(d) on the exercise of this Warrant), the number of shares of Common Stock of the successor
or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Fundamental Transaction by a holder of the number of
shares of Common Stock for which this Warrant is exercisable immediately prior to such Fundamental Transaction (without regard to any limitation in Section 2(d) on the exercise of this Warrant). For purposes of any such exercise, the
determination of the Exercise Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one share of Common Stock in such Fundamental Transaction, and the
Company shall apportion the Exercise Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the
securities, cash or property to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Fundamental Transaction.

 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. No adjustment in the number of Warrant
Shares purchasable hereunder shall be required unless such adjustment would require an 

  

 7 

 
increase or decrease of at least 1% in the number of Warrant Shares purchasable upon the exercise of this Warrant, provided, that any adjustments not
required by this Section 3(e) shall be carried forward and taken into account in any subsequent adjustment. 
 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 mail to the Holder 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 (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, of 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 mailed to the Holder at its last address as it shall appear upon the Warrant
Register of the Company, at least 20 calendar days prior to the applicable record or effective date hereinafter specified, or such shorter period of time as the Company reasonably determines is necessary so as not to negatively impact in a material
way the transaction that is the subject of the notice, 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 mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action
required to be specified in such notice. To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of its subsidiaries, the Company shall simultaneously file 

  

 8 

 
such notice with the Commission pursuant to a Current Report on Form 8-K. The Holder is 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. 
 g) Optional Exercise. 
 i. If, at any time after the fifteenth (15th) Trading Day following the date one or more Registration Statements (as defined in the Registration Rights Agreement), which have been declared effective by the Commission
(such date, the “Effective Date”), registers all Registrable Securities (as defined in the Registration Rights Agreement), (i) the VWAP is greater than $7.00 per share (as adjusted for any stock splits, stock dividends,
recapitalizations, combinations, reverse stock splits or other similar events during such period) on each Trading Day during ten (10) consecutive Trading Days (which period shall not begin until after such fifteenth (15th) Trading Day) (an “Optional Exercise Measuring Period”) and (ii) there is no Equity Conditions Failure (unless the Holder has
waived such Equity Conditions Failure), the Company shall have the right to require the Holder to exercise as of the Optional Exercise Date all or any portion of this Warrant not exceeding the amount of the then unexercised number of Warrant Shares
(an “Optional Exercise”) at an exercise price equal to the then applicable Exercise Price. The Company may exercise its right to require exercise of this Warrant under this Section 3(g) by delivering a written notice thereof by
facsimile and overnight courier to all, but not less than all, of the holders of the outstanding and the Company’s transfer agent (the “Optional Exercise Notice” and the date all of the holders received such notice is referred
to as the “Optional Exercise Notice Date”) no later than two (2) Trading Days after the applicable Optional Exercise Measuring Period. The Optional Exercise Notice delivered shall be irrevocable and shall state (A) the
date on which the Optional Exercise shall occur (the “Optional Exercise Date”) which date shall be at least ten (10) Trading Days after the Optional Exercise Notice Date, and (B) the aggregate number of Warrant Shares
which the Company has elected to be subject to Optional Exercise by all of the holders of the outstanding Warrants pursuant to this Section 3(g) (and analogous provisions under the other outstanding Warrants) on the Optional Exercise Date. The
Company may not effect more than one (1) Optional Exercise. Notwithstanding the foregoing, nothing in this subsection shall prevent the Holder from exercising this Warrant, in whole or part, prior to such Optional Exercise Date. 
 ii. Pro Rata Exercise Requirement. If the Company elects to cause an Optional Exercise pursuant to this Section 3(g), then it
must simultaneously take the same action with respect to the other outstanding Warrants. If the Company elects to cause an Optional Exercise pursuant to Section 3(g) (or similar provisions under the outstanding Warrants) with 

  

 9 

 
respect to less than all of the Warrant Shares underlying the Warrants then outstanding, then the Company shall require exercise of the Warrant Shares from
each of the holders of the outstanding Warrants equal to the product of (i) the aggregate number of Warrant Shares which the Company has elected to cause to be exercised pursuant to Section 3(g), multiplied by (ii) a fraction, the
numerator of which is the sum of the aggregate number of Warrant Shares underlying the Warrants issued to such holder pursuant to the Securities Purchase Agreement and the denominator of which is the sum of the aggregate number of Warrant Shares
underlying the Warrants issued to all holders pursuant to the Securities Purchase Agreement (such fraction with respect to each holder is referred to as its “Exercise Allocation Percentage”, and such amount with respect to each
holder is referred to as its “Pro Rata Exercise Amount”). Notwithstanding the foregoing, in the event the Company sends an Optional Exercise Notice and the Holder already exercised any portion of its Warrant prior to the Optional
Exercise Date (such exercised portion with respect to each Holder is referred to as its “Exercised Portion”), such Exercise Portion shall be applied against such Holder’s Pro Rata Exercise Amount and the Holder will only be
required to exercise the difference, if any, between such Holder’s Pro Rata Exercise Amount and such Holder’s Exercised Portion. In the event that the initial holder of any Warrants shall sell or otherwise transfer any of such
holder’s outstanding Warrants, the transferee shall be allocated a pro rata portion of such Holder’s Exercise Allocation Percentage and Pro Rata Exercise Amount. 
 As used herein, (x) “Equity Conditions” means: (i) on each day during the period beginning ten
(10) Trading Days prior to the Optional Exercise Notice Date and ending on and including the Optional Exercise Notice Date (the “Equity Conditions Measuring Period”), the Registration Statement filed pursuant to the
Registration Rights Agreement shall be effective for the resale of all of the Registrable Securities, in accordance with the terms of the Registration Rights Agreement; (ii) on each day during the Equity Conditions Measuring Period, the Common
Stock is designated for quotation on an Eligible Market and shall not have been suspended from trading on such Eligible Market (other than suspensions of not more than three (3) days and occurring prior to the applicable date of determination
due to business announcements by the Company) nor shall proceedings for such delisting or suspension by such Eligible Market have been commenced, threatened or pending either (A) in writing by such Eligible Market or (B) by falling below
the minimum listing maintenance requirements of such Eligible Market; (iii) on each day during the Equity Conditions Measuring Period, the Company shall have delivered Common Stock upon any exercise of the Warrants to the Holders on a timely
basis as set forth in Section 2(d) hereof; (iv) any applicable shares of Common Stock to be issued in connection with the event requiring determination may be issued in full without violating Section 2(d) hereof or the rules or

  

 10 

 
regulations of the applicable Eligible Market; (v) during the Equity Conditions Measuring Period, there shall not have occurred either the public
announcement of a pending, proposed or intended Fundamental Transaction which has not been abandoned, terminated or consummated; and (vi) the Company shall have no knowledge of any fact that would cause the Registration Statement(s) required
pursuant to the Registration Rights Agreement not to be effective and available for the resale of at least all of the Registrable Securities, in accordance with the terms of the Registration Rights Agreement, (y) “Equity Conditions
Failure” means that during the period commencing on the first Trading Day of the Equity Conditions Measuring Period through the Optional Exercise Date, the Equity Conditions have not been satisfied (or waived in writing by the Holder).

 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, and compliance with any applicable laws. 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. The
Warrant, if properly assigned, 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, if permitted by applicable law. All Warrants issued on transfers or exchanges shall be dated the Initial Exercise
Date 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. 
  

 11 

 d) Transfer Restrictions. If, at the time of the surrender of this Warrant in
connection with any transfer of this Warrant, the transfer of this Warrant 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 5.7 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. 
 f) Residual Obligation. In the event of any transfer of this Warrant, the initial Holder hereby guarantees payment of any liability
of the Holder that arises pursuant to Section 3(g) hereof. 
 Section 5. Miscellaneous. 
 a) No Rights as Stockholder Until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a
stockholder of the Company prior to the exercise hereof as set forth in Section 2(e)(i). 
 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, 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 Business Day, then, such action may be taken or such right may be exercised
on the next succeeding Business 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 

  

 12 

 
upon the exercise of any purchase rights under this Warrant. The Company further covenants that its issuance of this Warrant shall constitute full authority
to its officers who are charged with the duty of executing stock certificates to execute and issue the necessary certificates for the Warrant Shares upon the exercise of the 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, 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 (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. 
  

 13 

 g) Nonwaiver and Expenses. 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 Holder’s rights, powers or remedies. Without limiting any other provision of this Warrant or the Purchase Agreement, if the
Company willfully and knowingly fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to Holder such amounts as shall be sufficient to cover any costs and expenses including,
but not limited to, reasonable attorneys’ fees, including those of appellate proceedings, incurred by Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any of its rights, powers or remedies hereunder. 
 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. 
 i) Limitation of Liability. Other
than pursuant to an Optional Exercise in conformity with the requirements of Section 3(g), no provision hereof, in the absence of any affirmative action by Holder to exercise this Warrant to purchase Warrant Shares, and no enumeration herein of
the rights or privileges of Holder, shall give rise to any liability of 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 specific performance of its rights under this Warrant. The Company agrees that monetary damages would 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, if any, this Warrant and the rights and obligations evidenced hereby shall inure to the benefit of and be binding upon the successors of the Company and the successors
and permitted assigns of Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant and shall be enforceable by the Holder or holder of Warrant Shares. 
 l) Amendment. This Warrant (together with all other Warrants of this series) may be modified or amended or the provisions hereof
waived 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. 
  

 14 

 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.

WARRANTIES

lease, as the case may be, and to operate its properties and conduct its business as described in the SEC Reports, and is duly qualified to do business as a foreign corporation and is in good standing under the laws of each jurisdiction which

 8

Purchaser, hereby represents and warrants as of the date hereof and as of the Closing Date to the Company as follows (unless as of a specific date therein): 
 (a) Organization; Authority. Such Purchaser is an entity duly organized, validly existing and in good standing under the laws of
the jurisdiction of its organization with full right, corporate or partnership power and authority to enter into and to consummate the transactions contemplated by the Transaction Documents and otherwise to carry out its obligations hereunder and
thereunder. The execution and delivery of the Transaction Documents and performance by such Purchaser of the transactions contemplated by the Transaction Documents have been duly authorized by all necessary corporate, partnership, limited liability
company or similar action, as applicable, on the part of such Purchaser. Each Transaction Document to which it is a party has been duly executed by such Purchaser, and when delivered by such Purchaser in accordance with the terms hereof, will
constitute the valid and legally binding obligation of such Purchaser, enforceable against it in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium
and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar
as indemnification and contribution provisions may be limited by applicable law. 
 (b) Own Account. Such Purchaser
understands that the Securities are “restricted securities” and have not been registered under the Securities Act or any applicable state securities laws and is acquiring the Securities as principal for its own account and not with a view
to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities law, has no present intention of distributing any of such Securities in violation of the Securities Act or
any applicable state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or regarding the distribution of such Securities in violation of the Securities Act or any applicable state

acquiring the Securities hereunder in the ordinary course of its business. Such Purchaser understands that the Securities are not immediately free tradable and that the Purchaser may be required to hold such Securities for a period of time.

is, and on each date on which it exercises any Warrants, it will be either: (i) an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act or (ii) a “qualified
institutional buyer” as defined in Rule 144A(a) under the Securities Act. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the Exchange Act. 
 (d) Experience of Such Purchaser. Such Purchaser, either alone or together with its representatives, has such knowledge,

and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Securities, and has so evaluated the merits
and risks of such investment. Such Purchaser is able to bear the economic risk of an investment in the Securities and, at the present time, is able to afford a complete loss of such investment.

other communication regarding the Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or, to its knowledge, any other general solicitation or general advertisement.

 (f) Certain Transactions and Confidentiality. Other than consummating the transactions contemplated hereunder, such
Purchaser has not directly or indirectly, nor has any Person acting on behalf of or pursuant to any understanding with such Purchaser, executed any purchases or sales, including Short Sales, of the securities of the Company during the period
commencing as of the time that such Purchaser first received a term sheet (written or oral) as of the Company or any other Person representing the Company setting forth the material terms of the transactions contemplated hereunder and ending
immediately prior to the execution hereof. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Purchaser’s assets and the
portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such 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. Other than to other Persons party to this Agreement, such Purchaser has maintained the confidentiality of all disclosures made
to it in connection with this transaction (including the existence and terms of this transaction). Notwithstanding the foregoing, for avoidance of doubt, nothing contained herein shall constitute a representation or warranty, or preclude any
actions, with respect to the identification of the availability of, or securing of, available shares to borrow in order to effect Short Sales or similar transactions in the future. 
 (g) Certain Fees. Other than the fees payable to the Placement Agent, no brokerage or finder’s fees or commissions are or will

all information, documents and records included in the SEC Reports that Purchaser has deemed necessary in order to make an informed investment decision with respect to an investment in the Securities. Purchaser has had the opportunity to ask
representatives of the Company certain questions and request certain 

  

 19 

 
additional information regarding the terms and conditions of such investment and the finances, operations, business and prospects of the Company and has had
any and all such questions and requests answered to Purchaser’s satisfaction; and that Purchaser understands the risk and other considerations relating to such investment. 
 (i) Due Diligence. Purchaser acknowledges that it has sole responsibility for its own due diligence investigation and its own
investment decision. Purchaser understands that nothing in this Agreement or any other materials presented to such Purchaser in connection with the purchase and sale of the Securities constitutes legal, tax or investment advice. Such 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 Securities.

effect that such transfer does not require registration of such transferred Securities under the Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement and the Registration
Rights Agreement and shall have the rights and obligations of a Purchaser under this Agreement and the Registration Rights Agreement. 
 (b) The Purchasers agree to the imprinting, so long as is required by this Section 4.1, of a legend on any of the Securities in substantially the following form: 
 [NEITHER] THIS SECURITY [NOR THE SECURITIES INTO WHICH THIS SECURITY IS [EXERCISABLE] [CONVERTIBLE]] HAS [NOT] BEEN REGISTERED WITH THE SECURITIES AND
EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD 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 AND, UNLESS SOLD PURSUANT TO RULE 144 OR RULE 144A UNDER SAID ACT, AS 

  

 20 

 
EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. THIS SECURITY
[AND THE SECURITIES ISSUABLE UPON [EXERCISE] [CONVERSION] OF THIS SECURITY] MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT WITH A REGISTERED BROKER-DEALER OR OTHER LOAN WITH A FINANCIAL INSTITUTION THAT IS AN “ACCREDITED
INVESTOR” AS DEFINED IN RULE 501(a) UNDER THE SECURITIES ACT OR OTHER LOAN SECURED BY SUCH SECURITIES. 
 The Company
acknowledges and agrees that a Purchaser may, if done in compliance with all applicable laws and rules, from time to time pledge pursuant to a bona fide margin agreement with a registered broker-dealer or grant a security interest in some or all of
the Securities to a financial institution that is an “accredited investor” as defined in Rule 501(a) under the Securities Act and who agrees to be bound by the provisions of this Agreement and the Registration Rights Agreement and, if
required under the terms of such arrangement, such Purchaser may transfer, if done in compliance with all applicable laws and rules, pledged or secured Securities to the pledgees or secured parties. Such a pledge or transfer would not be subject to
approval of the Company and no legal opinion of legal counsel of the pledgee, secured party or pledgor shall be required in connection therewith. Further, no notice shall be required of such pledge. At the appropriate Purchaser’s expense, the
Company will execute and deliver such reasonable documentation as a pledgee or secured party of Securities may reasonably request in connection with a pledge or transfer of the Securities, including, if the Securities are subject to registration
pursuant to the Registration Rights Agreement, the preparation and filing of any required prospectus supplement under Rule 424(b)(3) under the Securities Act or other applicable provision of the Securities Act to appropriately amend the list of
Selling Stockholders (as defined in the Registration Rights Agreement) thereunder. 
 (c) Certificates evidencing the Shares
and Warrant Shares shall not contain any legend (including the legend set forth in Section 4.1(b) hereof): (i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under
the Securities Act, (ii) following any sale of such Shares or Warrant Shares pursuant to and in compliance with Rule 144 or (iii) if such Shares or Warrant Shares are eligible for sale under Rule 144, without the requirement for the
Company to be in compliance with the current public information required under Rule 144 as to such Shares and Warrant Shares and without volume or manner-of-sale restrictions. The Company shall cause its counsel to issue a legal opinion to the
Transfer Agent promptly after the Effective Date if required by the Transfer Agent to effect the removal of the legend hereunder. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover
the resale of the Warrant Shares, or if such Warrant Shares may be sold under Rule 144 and the Company is then in compliance with the current public information required under Rule 144, or if the Warrant Shares may be sold under Rule 144 without the
requirement for the Company to be in compliance with the current public information required under Rule 144 as to such Warrant Shares and without volume or manner-of-sale restrictions then such Warrant 

  

 21 

 
Shares shall be issued free of all legends. The Company agrees that following the Effective Date or at such time as such legend is no longer required under
this Section 4.1(c), it will, no later than three Trading Days following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Shares and Warrant Shares, as applicable, issued with a restrictive legend
(such third Trading Day, the “Legend Removal Date”), deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any
notation on its records or give instructions to the Transfer Agent that enlarge the restrictions on transfer set forth in this Section 4. Certificates for Shares and Warrant Shares subject to legend removal hereunder shall be transmitted by the
Transfer Agent to the Purchaser by crediting the account of the Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser. 
 (d) In addition to any other rights available to a Purchaser, if the Company fails to cause the Transfer Agent to transmit to such
Purchaser a certificate or the certificates representing the Shares or Warrant Shares without restrictive legend as required by this Section 4.1 on or before the Legend Removal Date (provided that such Purchaser has provided the Company with at
least 1 Trading Day’s prior written notice of such failure to deliver certificates without legends), and if after such date such Purchaser is required by its broker to purchase (in an open market transaction or otherwise) or such
Purchaser’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by such Purchaser of the Shares or Warrant Shares, as the case may be, which such Purchaser anticipated receiving upon such exercise (a
“Buy-In”), then the Company shall (A) pay in cash to such Purchaser the amount by which (x) such Purchaser’s total purchase price (including brokerage commissions, if any) for the shares of Common Stock so purchased
exceeds (y) the amount obtained by multiplying (1) the number of Shares or Warrant Shares, as the case may be, that the Company was required to deliver to such Purchaser in connection with the exercise at issue times (2) the price per
share at which the sell order giving rise to such purchase obligation was executed, and (B) if applicable and at the option of such Purchaser, either reinstate the portion of the Warrant and equivalent number of Warrant Shares for which such
exercise was not honored or deliver to such Purchaser the number of shares of Common Stock that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder against payment of the Exercise Price. For
example, if such Purchaser purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted exercise of shares of Common Stock with an aggregate sale price giving rise to such purchase obligation of
$10,000, under clause (1) of the immediately preceding sentence the Company shall be required to pay such Purchaser $1,000. Such Purchaser shall provide the Company written notice indicating the amounts payable to such Purchaser in respect of
the Buy-In and evidence of the amount of such loss. Nothing herein shall limit a Purchaser’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation, a decree of specific performance
and/or injunctive relief with respect to the Company’s failure to timely deliver certificates without legend as required pursuant to the terms hereof. 
  

 22 

 (e) Each Purchaser, severally and not jointly with the other Purchasers, agrees with the
Company that such Purchaser will pledge, secure, transfer or sell any Securities pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that
if Securities are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein, and acknowledges that the removal of the restrictive legend from certificates representing Securities as
set forth in this Section 4.1 is predicated upon the Company’s reliance upon this understanding. 
 4.2 Furnishing of
Information; Public Information. 
 (a) Until the earliest of the time that (i) no Purchaser owns Securities or
(ii) the Warrant Shares may be sold without registration or the availability of current public information under Rule 144, the Company covenants to timely file (or obtain extensions in respect thereof and file within the applicable grace
period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act even if the Company is not then subject to the reporting requirements of the Exchange Act. As long as any Purchaser owns Securities, if the
Company is not required to file reports pursuant to the Exchange Act, it will prepare and furnish to the Purchasers and make publicly available in accordance with Rule 144(c) such information as is required for the Purchasers to sell the Securities
under Rule 144. The Company further covenants that it will take such further action as any holder of Securities may reasonably request, to the extent required from time to time to enable such Person to sell such Securities without registration under
the Securities Act within the requirements of the exemption provided by Rule 144. 
 (b) At any time during the period commencing from the six (6) month anniversary of the date hereof and ending at such time that all of the Securities may be sold without the requirement for the Company to be in
compliance with Rule 144(c)(1) and otherwise without restriction or limitation pursuant to Rule 144, including, without limitation, Rule 144(i), if the Company shall fail for any reason to satisfy the current public information requirement under
Rule 144(c) (a “Public Information Failure”) then, in addition to such Purchaser’s other available remedies, the Company shall pay to a Purchaser, in cash, as partial liquidated damages and not as a penalty, by reason of any
such delay in or reduction of its ability to sell the Securities, an amount in cash equal to one percent (1.0%) of the aggregate Subscription Amount of such Purchaser’s Securities (not to exceed, in the aggregate, 3.0% of such
Purchaser’s Subscription Amount) plus any amount paid by such Purchaser upon exercise of any of the Warrants on the day of a Public Information Failure and on every thirtieth (30th) day (pro rated for periods totaling less than thirty days) thereafter until the earlier of (a) the date such Public Information Failure is cured and (b) such time
that such public information is no longer required for the Purchasers to transfer the Shares and Warrant Shares pursuant to Rule 144. The payments to which a Purchaser shall be entitled pursuant to this Section 4.2(b) are referred to
herein as “Public Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of (i) the last day of the calendar month during which such Public Information Failure Payments are incurred
and (ii) the third (3rd) Business Day after the event or failure giving rise to the Public Information Failure 

  

 23 

 
Payments is cured. In the event the Company fails to make Public Information Failure Payments in a timely manner, such Public Information Failure
Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. Nothing herein shall limit such Purchaser’s right to pursue actual damages for the Public Information Failure, and such Purchaser
shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief. 
 4.3 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any security (as defined in Section 2 of the Securities Act) that would be
integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities or that would be integrated with the offer or sale of the Securities for purposes of the rules
and regulations of any Trading Market such that it would require shareholder approval prior to the closing of such other transaction unless shareholder approval is obtained before the closing of such subsequent transaction. 
 4.4 Securities Laws Disclosure; Publicity. The Company shall, by 9:30 a.m. (New York City time) on the Trading Day immediately following the date
hereof, issue a press release disclosing the material terms of the transactions contemplated hereby, and within 4 Trading Days of the date hereof file a Current Report on Form 8-K, including the Transaction Documents as exhibits thereto. From and
after the issuance of such press release, the Company shall have publicly disclosed all material, non-public information delivered to any of the Purchasers by the Company or any of its subsidiaries, or any of their respective officers, directors,
employees or agents in connection with the transactions contemplated by the Transaction Documents. The Company and each Purchaser shall consult with each other in issuing any other press releases with respect to the transactions contemplated hereby,
and neither the Company nor any Purchaser shall issue any such press release nor otherwise make any such public statement without the prior consent of the Company, with respect to any press release of any Purchaser, or without the prior consent of
each Purchaser, with respect to any press release of the Company, which consent shall not unreasonably be withheld or delayed, except if such disclosure is required by law or Trading Market regulation, in which case the disclosing party shall
promptly provide the other party with prior notice of such public statement or communication. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with
the Commission or any regulatory agency or Trading Market, without the prior written consent of such Purchaser, except (a) as required by federal securities law in connection with (i) any registration statement contemplated by the
Registration Rights Agreement and (ii) the filing of final Transaction Documents (including signature pages thereto) with the Commission and (b) to the extent such disclosure is required by law or Trading Market regulations, in which case
the Company shall provide the Purchasers with prior notice of such disclosure permitted under this clause (b). 
 4.5 Non-Public
Information. Except with respect to the material terms and conditions of the transactions contemplated by the Transaction Documents, the Company covenants and agrees that neither it, nor any other Person acting on its behalf will provide any
Purchaser or its agents or counsel with any information that the Company believes constitutes material non-public information, unless prior thereto such Purchaser shall have executed a written agreement regarding the confidentiality and use of such
information. The Company understands and confirms that each Purchaser shall be relying on the foregoing covenant in effecting transactions in securities of the Company.

 4.6 RESERVED. 
 4.7 Indemnification of Purchasers. Subject to the provisions of this Section 4.8, the Company will indemnify and hold each Purchaser and its directors, officers, shareholders, members, partners, employees
and agents (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title), each Person who controls such Purchaser (within the meaning of Section 15 of the
Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a
lack of such title or any other title) of such controlling persons (each, a “Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments,
amounts paid in settlements, court costs and reasonable attorneys’ fees and costs of investigation that any such Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties,
covenants or agreements made by the Company in this Agreement or in the other Transaction Documents or (b) any action instituted against a Purchaser in any capacity, or any of them or their respective Affiliates, by any stockholder of the
Company who is not an Affiliate of such Purchaser, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of any Purchaser Party’s representations, warranties or covenants
under the Transaction Documents or any agreements or understandings such Purchaser may have with any such stockholder or any violations by any Purchaser Party of state or federal securities laws or any conduct by any Purchaser Party which
constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify
the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser Party. Any Purchaser Party shall have the right to employ separate counsel in any such
action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that (i) the employment thereof has been specifically authorized by the Company in
writing, (ii) the Company has failed after a reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of such separate counsel, a material conflict on any material
issue between the position of the Company and the position of such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more than one such separate counsel. The Company will not be liable to any
Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably withheld or delayed; or (z) to the extent, but only to the extent
that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such Purchaser Party in this Agreement or in the other Transaction Documents.

 4.8 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 

  

 25 

 
rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares
pursuant to any exercise of the Warrants. 
 4.9 Listing of Common Stock. The Company hereby agrees to use its best efforts to cause
the Shares and Warrant Shares to be approved for listing upon notice of issuance by The New York Stock Exchange as promptly as practicable, but in no later than the close of trading on the Closing Date and shall use best efforts to maintain the
listing and quotation of the Common Stock on a Trading Market. The Company further agrees, if the Company applies to have the Common Stock traded on any other Trading Market, it will then include in such application all of the Shares and Warrant
Shares, and will take such other action as is necessary to cause all of the Shares and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue
the listing and trading of its Common Stock on a Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market. 
 4.10 Equal Treatment of Purchasers. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any
provision of this Agreement (but only to the extent such waiver or modification effects the right of such Purchaser) unless the same consideration is also offered to all of the parties to this Agreement. For clarification purposes, this provision
constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in
concert or as a group with respect to the purchase, disposition or voting of Securities or otherwise. 
 4.11 RESERVED. 
 4.12 Subsequent Equity Sales. 
 (a) From the date hereof until 30 days after the Effective Date, neither the Company nor any Subsidiary shall issue, enter into any agreement to issue or announce the issuance or proposed issuance of any shares of Common Stock or Common
Stock Equivalents, other than Exempt Issuances. 
 (b) Notwithstanding the foregoing, this Section 4.12 shall not apply
in respect of an Exempt Issuance. 
 4.13 Certain Transactions and Confidentiality. Each Purchaser, severally and not jointly with the
other Purchasers, covenants that neither it, nor any Affiliate acting on its behalf or pursuant to any understanding with it will execute any purchases or sales, including Short Sales, of any of the Company’s securities during the period
commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4. Each Purchaser,
severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement are publicly disclosed by the Company pursuant to the initial press release as described in Section 4.4, such
Purchaser will maintain the 

  

 26 

 
confidentiality of the existence and terms of this transaction and the information included in the Transaction Documents and the Disclosure
Schedules. Notwithstanding the foregoing, and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that (i) no Purchaser makes any representation, warranty or covenant hereby
that it will not engage in effecting transactions in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in
Section 4.4, (ii) no Purchaser shall be restricted or prohibited by the terms of this Agreement from effecting any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the
transactions contemplated by this Agreement are first publicly announced pursuant to the initial press release as described in Section 4.4 and (iii) no Purchaser shall have any duty of confidentiality to the Company or its Subsidiaries
after the issuance of the initial press release as described in Section 4.4. Notwithstanding the foregoing, in the case of a Purchaser that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions
of such Purchaser’s assets and the portfolio managers have no direct knowledge of the investment decisions made by the portfolio managers managing other portions of such Purchaser’s assets, the covenant 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. 
 4.14 Form D; Blue Sky Filings. The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The
Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchasers at the Closing under applicable securities or “Blue Sky”
laws of the states of the United States, and shall provide evidence of such actions promptly upon request of any Purchaser. 
 ARTICLE V.

 MISCELLANEOUS 
 5.1
Termination. This Agreement may be terminated by any Purchaser, as to such Purchaser’s obligations hereunder only and without any effect whatsoever on the obligations between the Company and the other Purchasers, by written notice
to the other parties, if the Closing has not been consummated on or before June 9, 2009; provided, however, that no such termination will affect the right of any party to sue for any breach by the other party (or parties).

 5.2 Fees and Expenses. Except as expressly set forth in the Transaction Documents to the contrary, each party shall pay the fees

Shares then outstanding or, in the case of a waiver, by the party against whom enforcement of any such waived provision is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to
be a continuing waiver 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. 
 5.6 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement
and shall not be deemed to limit or affect any of the provisions hereof. 
 5.7 Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of the parties and their successors and permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser (other than by
merger). Any Purchaser may assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Warrants, upon notice to the Company, provided such transferee is an “accredited investor” and
agrees in writing to be bound, with respect to the transferred Warrants, by the provisions of the Transaction Documents that apply to the “Purchasers.” 
 5.8 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 4.8. 
 5.9 Governing Law. All questions
concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and 

  

 28 

 
enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that
all legal proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors,
officers, shareholders, employees or agents) shall be commenced exclusively in the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting
in the City of New York, borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the
Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is improper or
is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof via registered or certified mail or
overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained
herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action or proceeding to enforce any provisions of the Transaction Documents, then the prevailing party in
such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such action or proceeding. 
 5.10 Survival. The representations and warranties contained herein shall survive the Closing and the delivery of the Securities for the applicable
statute of limitations under the Securities Act or the Exchange Act. 
 5.11 Execution. This Agreement may be executed in two or more
counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need
not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or
on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 
 5.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms,
provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an
alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the
remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 
  

 29 

 5.13 Replacement of Securities. If any certificate or instrument evidencing any Securities is
mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument,
but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including
customary bond or indemnity) associated with the issuance of such replacement Securities. 
 5.14 Remedies. In addition to being
entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary
damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agrees to waive and not to assert in any action for specific performance of any such obligation
the defense that a remedy at law would be adequate. 
 5.15 Payment Set Aside. To the extent that the Company makes a payment or
payments to any Purchaser pursuant to any Transaction Document or a Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other person under any law (including, without limitation, any
bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as
if such payment had not been made or such enforcement or setoff had not occurred. 
 5.16 Independent Nature of Purchasers’
Obligations and Rights. The obligations of each Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or
non-performance of the obligations of any other Purchaser under any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by
the Transaction Documents. Each Purchaser shall be entitled to independently protect and enforce its rights including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be
necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in their review and negotiation of the Transaction Documents. For reasons
of administrative convenience only, Purchasers and their respective counsel have chosen to communicate with the Company through WS. WS does not represent all of the Purchasers but only Rodman & Renshaw, LLC, the placement agent for the
transactions contemplated hereby. The Company has elected to provide all Purchasers with the same terms and Transaction Documents for the convenience of the Company and not because it was required or requested to do so by the Purchasers. 

 

 30 

 5.17 Liquidated Damages. The Company’s obligations to pay any partial liquidated damages or
other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or
security pursuant to which such partial liquidated damages or other amounts are due and payable shall have been canceled.
