 HARKEN ENERGY CORPORATION 
  
 PURCHASE WARRANT 
  
 WARRANT (“WARRANT”) TO PURCHASE SHARES OF 
 COMMON STOCK, $0.01 PAR VALUE PER SHARE 
  
 This is to certify that, FOR VALUE RECEIVED,
[                                ] (“Warrantholder”), is entitled to
purchase, subject to the provisions of this Warrant, from HARKEN ENERGY CORPORATION, a corporation organized under the laws of Delaware (“Company”), at any time and from time to time after the issuance hereof but not later than 5:00 P.M.,
Eastern time, on the second (2nd) anniversary (“Expiration Date”) of the date on which the Registration
Statement (as defined in the Registration Rights Agreement) covering the resale of the Warrant Shares is declared effective by the SEC,
                     shares (“Warrant Shares”) of Common Stock, $0.01 par value (“Common Stock”), of the Company, at an
exercise price per share equal to $0.57 (the exercise price in effect from time to time hereafter being herein called the “Warrant Price”). The number of Warrant Shares purchasable upon exercise of this Warrant and the Warrant Price shall
be subject to adjustment from time to time as described herein. 
  
 This Warrant has been issued pursuant to the terms of the Purchase Agreement (“Purchase Agreement”) dated on or about the date hereof between the Company and the Warrantholder. Capitalized terms used herein and not defined shall
have the meaning specified in the Purchase Agreement. 
  
 Section
1. Registration. The Company shall maintain books for the transfer and registration of the Warrant. Upon the initial issuance of the Warrant, the Company shall issue and register the Warrant in the name of the Warrantholder. 

 Section 2. Transfers. As provided herein, this Warrant may be transferred only pursuant to a
registration statement filed under the Securities Act of 1933, as amended (“Securities Act”) or an exemption from registration thereunder. Subject to such restrictions, the Company shall transfer this Warrant from time to time, upon the
books to be maintained by the Company for that purpose, upon surrender hereof for transfer properly endorsed or accompanied by appropriate instructions for transfer upon any such transfer, and a new Warrant of like tenor shall be issued to the
transferee and the surrendered Warrant shall be canceled by the Company. 
  
 Section 3. 
  
 (a) Exercise of
Warrant. Subject to the provisions hereof, the Warrantholder may exercise this Warrant in whole or in part at any time and from time to time on and after the issuance hereof upon surrender of the Warrant, together with delivery of the duly
executed Warrant exercise form attached hereto (the “Exercise Agreement”) (which may be by fax), to the Company during normal business hours on any business day at the Company’s principal executive offices (or such other office or
agency of the Company as it may designate by notice to the holder hereof), and upon payment to the Company in cash, by certified or official bank check or by wire transfer for the account of the Company of the Warrant Price for the Warrant Shares
specified in the Exercise Agreement. The Warrant Shares so purchased shall be deemed to be issued to the holder hereof or such holder’s designee, as the record owner of such shares, as of the close of business on the date on which the completed
Exercise Agreement shall have been delivered to the Company (or such later date as may be specified in the Exercise Agreement) (provided that the exercise price therefore shall have been paid within five (5) Trading Days thereafter as a condition
subsequent to such Warrant Shares being deemed issued on such date). Certificates for the Warrant Shares so purchased, representing the aggregate number of shares specified in the Exercise Agreement, shall be delivered to the holder hereof within a
reasonable time, not exceeding five (5) business days, after this Warrant shall have been so exercised. The certificates so delivered shall be in such denominations as may be requested by the holder hereof and shall be registered in the name of such
holder or such other name as shall be designated by such holder. If this Warrant shall have been exercised only in part, then, unless this Warrant has expired, the Company shall (subject to Section 3(b) below), at its expense, at the time of
delivery of such certificates, deliver to the holder a new Warrant representing the number of shares with respect to which this Warrant shall not then have been exercised. . In lieu of delivering physical certificates representing the shares of
Common Stock issuable upon exercise of this Warrant, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon
request of the Warrantholder, the Company shall use commercially reasonable efforts to cause its transfer agent to electronically transmit such shares issuable upon exercise to the Warrantholder (or its designee), by crediting the account of the
Warrantholder’s (or such designee’s) prime broker with DTC through its Deposit Withdrawal Agent Commission system (provided that the same time periods herein as for stock certificates shall apply). 
  
 (b) Book-Entry. Notwithstanding anything to the contrary set forth
herein, upon exercise of any portion of this Warrant in accordance with the terms hereof, the Warrantholder shall not be required to physically surrender this Warrant to the Company unless such holder is purchasing the full amount of Warrant Shares
represented by this Warrant. The Warrantholder 
  

 2 

 and the Company shall maintain records showing the number of Warrant Shares so purchased hereunder and the dates of such
purchases or shall use such other method, reasonably satisfactory to the Warrantholder and the Company, so as not to require physical surrender of this Warrant upon each such exercise. In connection therewith a form of ledger to maintain a record of
such transactions is attached hereto. The Warrantholder and any assignee, by acceptance of this Warrant or a new Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following exercise of any portion of this Warrant,
the number of Warrant Shares which may be purchased upon exercise of this Warrant may be less than the number of Warrant Shares set forth on the face hereof. 
  
 (c) Cashless Exercise. Notwithstanding anything to the contrary contained in Section 3(a), if at any time after one year from the date of issuance
of this Warrant there is no effective Registration Statement registering the resale of the Warrant Shares by the Warrantholder, the Warrantholder shall have the right to pay the aggregate Warrant Price by “Cashless Exercise”. To effect a
Cashless Exercise, the holder shall submit to the Company on the Exercise Agreement written notice of the holder’s intention to do so, including a calculation of the number of shares of Common Stock to be issued upon such exercise in accordance
with the terms hereof. In the event of a Cashless Exercise, in lieu of paying the Warrant Price in cash, the holder shall surrender this Warrant for that number of shares of Common Stock determined by multiplying the number of Warrant Shares to
which it would otherwise be entitled by a fraction, the numerator of which shall be the difference between the then current Fair Market Value per share of the Common Stock and the applicable Warrant Price, and the denominator of which shall be the
then current Fair Market Value per share of the Common Stock. For this purpose, the “Fair Market Value” of the Common Stock shall be the average of the closing sale prices of the Common Stock as reported by the Principal Market for the ten
(10) Trading Days immediately preceding the date of the Exercise Agreement. 
  
 Section 4. Compliance with the Securities Act of 1933. Neither this Warrant nor the Common Stock issued upon exercise hereof nor any other security issued or issuable upon exercise of this Warrant may be
offered or sold except as provided in this Warrant and in conformity with the Securities Act of 1933, as amended, and then only against receipt of an agreement of such person to whom such offer of sale is made to comply with the provisions of this
Section 4 with respect to any resale or other disposition of such security. The Company may cause the legend set forth on the first page of this Warrant to be set forth on each Warrant or similar legend on any security issued or issuable upon
exercise of this Warrant until the Warrant Shares have been registered for resale under the Registration Rights Agreement or until Rule 144 is available, unless counsel for the Company is of the opinion as to any such security that such legend is
unnecessary. 
  
 Section 5. Payment of Taxes. The Company
will pay any documentary stamp taxes attributable to the initial issuance of Warrant Shares issuable upon the exercise of the Warrant; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect
of any transfer involved in the issuance or delivery of any certificates for Warrant Shares in a name other than that of the registered holder of this Warrant in respect of which such shares are issued. The holder shall be responsible for income
taxes due under federal or state law, if any such tax is due. 
  

 3 

 Section 6. Mutilated or Missing Warrants. In case this Warrant shall be mutilated, lost, stolen,
or destroyed, the Company shall issue in exchange and substitution of and upon cancellation of the mutilated Warrant, or in lieu of and substitution for the Warrant lost, stolen or destroyed, a new Warrant of like tenor and for the purchase of a
like number of Warrant Shares, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction of the Warrant, and with respect to a lost, stolen or destroyed Warrant, reasonable indemnity or bond with
respect thereto, if reasonably requested by the Company. 
  
 Section 7. Reservation of Common Stock. The Company hereby represents and warrants that there have been reserved, and the Company shall at all applicable times keep reserved, out of the authorized and unissued Common Stock, a number
of shares sufficient to provide for the exercise of the rights of purchase represented by the Warrant in full (without regard to any restrictions on beneficial ownership contained herein), and the transfer agent for the Common Stock, including every
subsequent transfer agent for the Common Stock or other shares of the Company’s capital stock issuable upon the exercise of any of the right of purchase aforesaid (“Transfer Agent”), shall be irrevocably authorized and directed at all
times to reserve such number of authorized and unissued shares of Common Stock as shall be requisite for such purpose. The Company agrees that all Warrant Shares issued upon exercise of the Warrant in accordance with its terms shall be, at the time
of delivery of the certificates for such Warrant Shares, duly authorized, validly issued, fully paid and non-assessable shares of Common Stock of the Company. 
  

Section 8. Warrant Price. The Warrant Price, subject to adjustment as provided in Section 9, shall, if payment is made in cash or by certified
check, be payable in lawful money of the United States of America. 
  
 Section 9. Adjustments. Subject and pursuant to the provisions of this Section 9, the Warrant Price and number of Warrant Shares subject to this Warrant shall be subject to adjustment from time to time as set forth hereinafter.

  
 (a) If the Company or any of its subsidiaries shall at any
time or from time to time while the Warrant is outstanding, pay a dividend or make a distribution on its capital stock in shares of Common Stock, subdivide its outstanding shares of Common Stock into a greater number of shares or combine its
outstanding shares into a smaller number of shares or issue by reclassification of its outstanding shares of Common Stock any shares of its capital stock (including any such reclassification in connection with a consolidation or merger in which the
Company is the continuing corporation), then the number of Warrant Shares purchasable upon exercise of the Warrant and the Warrant Price in effect immediately prior to the date upon which such change shall become effective, shall be adjusted by the
Company so that the Warrantholder thereafter exercising the Warrant shall be entitled to receive the number of shares of Common Stock or other capital stock which the Warrantholder would have received if the Warrant had been exercised immediately
prior to such event. Such adjustment shall be made successively whenever any event listed above shall occur. 
  
 (b) If any capital reorganization, reclassification of the capital stock of the Company, consolidation or merger of the Company with another corporation,
or sale, transfer or 
  

 4 

 other disposition of all or substantially all of the Company’s assets to another corporation shall be effected,
then, as a condition of such reorganization, reclassification, consolidation, merger, sale, transfer or other disposition, lawful and adequate provision shall be made whereby each Warrantholder shall thereafter have the right to purchase and receive
upon the basis and upon the terms and conditions herein specified and in lieu of the Warrant Shares immediately theretofore issuable upon exercise of the Warrant, such shares of stock, securities or assets as would have been issuable or payable with
respect to or in exchange for a number of Warrant Shares equal to the number of Warrant Shares immediately theretofore issuable upon exercise of the Warrant, had such reorganization, reclassification, consolidation, merger, sale, transfer or other
disposition not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of each Warrantholder to the end that the provisions hereof (including, without limitations, provision for adjustment of
the Warrant Price) shall thereafter be applicable, as nearly equivalent as may be practicable in relation to any shares of stock, securities or properties thereafter deliverable upon the exercise hereof. The Company shall not effect any such
consolidation, merger, sale, transfer or other disposition unless prior to or simultaneously with the consummation thereof the successor corporation (if other than the Company) resulting from such consolidation or merger, or the corporation
purchasing or otherwise acquiring such assets or other appropriate corporation or entity shall assume, by written instrument executed and delivered to the Company, the obligation to deliver to the holder of the Warrant such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such holder may be entitled to purchase and the other obligations under this Warrant. The provisions of this paragraph (b) shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, sales, transfers or other dispositions. 
  
 (c) In case the Company shall fix a record date for the making of a distribution to all holders of Common Stock (including any such distribution made in connection with a consolidation or merger in which the Company
is the continuing corporation) of evidences of indebtedness or assets or subscription rights or warrants, the Warrant Price to be in effect after such record date shall be determined by multiplying the Warrant Price in effect immediately prior to
such record date by a fraction, the numerator of which shall be the total number of shares of Common Stock outstanding multiplied by the Closing Price per share of Common Stock (as defined below), less the fair market value (on a per share basis)
(as determined by the Company’s Board of Directors in good faith) of said assets or evidences of indebtedness so distributed, or of such subscription rights or warrants, and the denominator of which shall be the total number of shares of Common
Stock outstanding multiplied by such Closing Price per share of Common Stock. Such adjustment shall be made successively whenever such a record date is fixed. “Closing Price” of the Common Stock shall be the closing sale price per share of
the Common Stock as reported by the Principal Market on the Trading Day immediately preceding the date on which such value is being determined. 
  
 (d) In the event that the Company or any of its subsidiaries (A) issues or sells any Common Stock or Convertible Securities, or any warrants or other
rights to subscribe for or to purchase or any options for the purchase of Common Stock or (B) directly or indirectly effectively reduces the conversion, exercise or exchange price for any Convertible Securities which are currently outstanding (other
than pursuant to terms existing on the date hereof), at or to an effective Per Share Selling Price (as defined in the Certificate) which is less than the greater of 
  

 5 

 (A) the closing price on the Trading Day next preceding such issue or sale or, in the case of issuances to holders of its
Common Stock, the date fixed for the determination of stockholders entitled to receive such warrants, rights, or options, or (B) the then applicable Warrant Price, then in each such case, the Warrant Price in effect immediately prior to such issue
or sale or record date, as applicable, shall be automatically reduced effective concurrently with such issue or sale to an amount determined by multiplying the Warrant Price then in effect by a fraction, (x) the numerator of which shall be the sum
of (1) the number of shares of Common Stock outstanding immediately prior to such issue or sale, plus (2) the number of shares of Common Stock which the aggregate consideration received by the Company for such additional shares would purchase at
such closing price or Warrant Price, as the case may be, and (y) the denominator of which shall be the number of shares of Common Stock of the Company outstanding immediately after such issue or sale. 
  
 The foregoing provisions of this subsection shall not apply to issuances or
sales of (x) the Securities, (y) Common Stock upon conversion, exercise or exchange of Convertible Securities outstanding on the issuance date hereof in accordance with the terms in effect on such issuance date, or (z) Common Stock or Convertible
Securities under the Company’s duly adopted stock option and bonus plans for employees and directors. For the purposes of the foregoing adjustments, in the case of the issuance of any Convertible Securities, the maximum number of shares of
Common Stock issuable upon exercise, exchange or conversion of such Convertible Securities shall be deemed to be outstanding, provided that no further adjustment shall be made upon the actual issuance of Common Stock upon exercise, exchange or
conversion of such Convertible Securities. For purposes of this Section, if an event occurs that triggers more than one of the above adjustment provisions, then only one adjustment shall be made and the calculation method which yields the greatest
downward adjustment in the Warrant Price shall be used. 
  
 (e) An
adjustment shall become effective immediately after the record date in the case of each dividend or distribution and immediately after the effective date of each other event which requires an adjustment. 
  
 (f) In the event that, as a result of an adjustment made pursuant to Section
9, the holder of this Warrant shall become entitled to receive any shares of capital stock of the Company other than shares of Common Stock, the number of such other shares so receivable upon exercise of this Warrant shall be subject thereafter to
adjustment from time to time in a manner and on terms as nearly equivalent as practicable to the provisions with respect to the Warrant Shares contained in this Warrant. 
  
 (g) In the event of any adjustment in the number of Warrant Shares issuable hereunder upon exercise, the Warrant Price shall
be inversely proportionately increased or decreased, as the case may be, such that the aggregate purchase price for Warrant Shares upon full exercise of this Warrant shall remain the same. Similarly, in the event of any adjustment in the Warrant
Price, the number of Warrant Shares issuable hereunder upon exercise shall be inversely proportionately increased or decreased, as the case may be, such that the aggregate purchase price for Warrant Shares upon full exercise of this Warrant shall
remain the same. 
  

 6 

 Section 10. Fractional Interest. The Company shall not be required to issue fractions of Warrant
Shares upon the exercise of the Warrant. If any fraction of a Warrant Share would, except for the provisions of this Section, be issuable upon the exercise of the Warrant (or specified portions thereof), the Company shall round such calculation to
the nearest whole number and disregard the fraction. 
  
 Section
11. Benefits. Nothing in this Warrant shall be construed to give any person, firm or corporation (other than the Company and the Warrantholder) any legal or equitable right, remedy or claim, it being agreed that this Warrant shall be for the
sole and exclusive benefit of the Company and the Warrantholder. 
  
 Section 12. Notices to Warrantholder. Upon the happening of any event requiring an adjustment of the Warrant Price, the Company shall forthwith give written notice thereof to the Warrantholder at the address appearing in the records
of the Company, stating the adjusted Warrant Price and the adjusted number of Warrant Shares resulting from such event and setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. In the event
of a dispute with respect to any such calculation, the certificate of the Company’s independent certified public accountants shall be conclusive evidence of the correctness of any computation made, absent manifest error. Failure to give such
notice to the Warrantholder or any defect therein shall not affect the legality or validity of the subject adjustment. At the Warrantholder’s request, the Company shall deliver to the Warrantholder as of a requested date a notice specifying the
Warrant Price and the number of Warrant Shares into which this Warrant is exercisable as of such date. 
  
 Section 13. Identity of Transfer Agent. The initial Transfer Agent for the Common Stock is: 
  
 American Stock Transfer & Trust Company 
 59 Maiden Lane, Plaza Level 
 New York, NY 10038 
  
 Forthwith
upon the appointment of any subsequent transfer agent for the Common Stock or other shares of the Company’s capital stock issuable upon the exercise of the rights of purchase represented by the Warrant, the Company will fax to the Warrantholder
a statement setting forth the name and address of such transfer agent. 
  
 Section 14. Notices. Any notice pursuant hereto to be given or made by the Warrantholder to or on the Company shall be sufficiently given or made if delivered personally or by facsimile or if sent by an internationally recognized
courier, addressed as follows:

 or such other address as the Company may specify in writing by notice to the Warrantholder complying as to delivery with
the terms of this Section 14. 
  
 Any notice pursuant hereto to be
given or made by the Company to or on the Warrantholder shall be sufficiently given or made if personally delivered or if sent by an internationally recognized courier service by overnight or two-day service, to the address set forth on the books of
the Company or, as to each of the Company and the Warrantholder, at such other address as shall be designated by such party by written notice to the other party complying as to delivery with the terms of this Section 14. 
  
 All such notices, requests, demands, directions and other communications
shall, when sent by courier, be effective two (2) days after delivery to such courier as provided and addressed as aforesaid. All faxes shall be effective upon receipt. 
  
 Section 15. Registration Rights. The initial holder of this Warrant is entitled to the benefit of certain
registration rights in respect of the Warrant Shares as provided in the Registration Rights Agreement. 
  
 Section 16. Successors. All the covenants and provisions hereof by or for the benefit of the Warrantholder shall bind and inure to the benefit of
its respective successors and assigns hereunder. 
  
 Section 17.
Governing Law. This Warrant shall be deemed to be a contract made under the laws of the State of New York, without giving effect to its conflict of law principles, and for all purposes shall be construed in accordance with the laws of said
State. 
  
 Section 18. 9.9% Limitation. Notwithstanding
anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by the holder upon exercise pursuant to the terms hereof shall not exceed a number that, when added to the total number of shares of Common Stock
deemed beneficially owned by such holder at such time (other than by virtue of the ownership of securities or rights to acquire securities (including the Preferred Shares and Warrant Shares) that have limitations on the holder’s right to
convert, exercise or purchase similar to the limitation set forth herein), together with all shares of Common Stock deemed beneficially owned (other than by virtue of the ownership of securities or rights to acquire securities that have limitations
on the right to convert, exercise or purchase similar to the limitation set forth herein) by the Warrantholder’s “affiliates” at such time (as defined in Rule 144 of the Act) (“Aggregation Parties”) that would be aggregated
for purposes of determining whether a group under Section 13(d) of the Securities Exchange Act of 1934, as amended, exists, would exceed 9.9% of the total issued and outstanding shares of the Common Stock (the “Restricted Ownership
Percentage”). Each holder shall have the right at any time and from time to time to reduce its Restricted Ownership Percentage immediately upon notice to the Company. 
  
 Section 19. Replacement Warrants. The Company agrees that within ten (10) business days after any request from time
to time of the Warrantholder, it shall deliver to such holder a new Warrant in substitution of this Warrant which is identical in all respects except that 
  

 8 

 the then Warrant Price shall be appropriately specified in the Warrant, and the Warrant shall specify the fixed number of
Warrant Shares into which this Warrant is then exercisable. Such changes are intended not as amendments to the Warrant but only as clarification of the foregoing numbers for convenience purposes, and such changes shall not affect any provisions
concerning adjustments to the Warrant Price or number of Warrant Shares contained herein. 
  
 Section 20. Absolute Obligation to Issue Warrant Shares. The Company’s obligations to issue and deliver Warrant Shares in accordance with the terms hereof are absolute and unconditional, irrespective of
any action or inaction by the holder hereof to enforce the same, any waiver or consent with respect to any provision hereof, the recovery of any judgment against any Person or any action to enforce the same, or any setoff, counterclaim, recoupment,
limitation or termination, or any breach or alleged breach by the holder hereof or any other Person of any obligation to the Company or any violation or alleged violation of law by the holder or any other Person, and irrespective of any other
circumstance which might otherwise limit such obligation of the Company to the holder hereof in connection with the issuance of Warrant Shares. The Company will at no time close its shareholder books or records in any manner which interferes with
the timely exercise of this Warrant. 
  
 Section 21.
Assignment, Etc. The Warrantholder may assign or transfer this Warrant to any transferee only with the prior written consent of the Company, which may not be unreasonably withheld or delayed, provided that the Warrantholder may assign or
transfer this Warrant to any of such Warrantholder’s affiliates without the consent of the Company. The Warrantholder shall notify the Company of any such assignment or transfer promptly. This Warrant shall be binding upon the Company and its
successors and shall inure to the benefit of the Warrantholder and its successors and permitted assigns.

above.

 PREFERRED STOCK PURCHASE AGREEMENT 
  
 THIS PREFERRED STOCK PURCHASE AGREEMENT (“Agreement”) is made as of the 7th day of October, 2004 by and among HARKEN ENERGY CORPORATION, a Delaware corporation (the “Company”), and the Purchasers set forth on the
signature page affixed hereto (each a “Purchaser” and collectively the “Purchasers”). 
  
 Recitals 
  
 A. The Company and the Purchasers are executing and delivering this Agreement in reliance upon the exemption from securities registration afforded by the provisions of Regulation D (“Regulation D”), as promulgated by the U.S.
Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended;

amended, and the rules and regulations promulgated thereunder, and applicable state securities laws; and 
  
 In consideration of the mutual promises made herein and for other good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties hereto agree as follows: 
  
 Definitions. In addition to those terms defined above and elsewhere in this Agreement, for the purposes of this Agreement, the following terms shall have the meanings here set forth:

conducted and own its properties. The Company is duly qualified to do business as a foreign corporation and is in good standing in each jurisdiction in which the conduct of its business or its ownership or leasing of property makes such

stockholders necessary for (i) the authorization, execution and delivery of the Agreements, (ii) authorization of the performance of all obligations of the Company hereunder and thereunder, and (iii) the authorization, issuance (or reservation for

and pursuant to the conversion or exercise of outstanding Convertible Securities. All of the issued and outstanding shares of the Company’s capital stock have been duly authorized and validly issued and are fully paid and nonassessable, except
to the extent that the failure of the foregoing to be true and correct would not have a Material Adverse Effect. Other than as set forth in the SEC Filings, no Person is entitled to preemptive or similar statutory or contractual rights with respect
to any securities of the Company. Other than as set forth in the SEC Filings, there are no outstanding warrants, options, convertible securities or other rights, agreements or arrangements of any character under which the Company is or may be

kind among any of the securityholders of the Company relating to the securities of the Company held by them. Other than as set forth in the SEC Filings, the Company has not granted any Person the right to require the Company to register any
securities of the Company under the 1933 Act, whether on a demand basis or in connection with the registration of securities of the Company for its own account or for the account of any other Person.

default under (i) the Company’s Certificate of Incorporation (including any certificates of designation) or the Company’s Bylaws, both as in effect on the date hereof (copies of which have been provided to the Purchasers before the date
hereof), or (ii) except where it would not have a Material Adverse Effect, (A) any statute, rule, regulation or order of any governmental agency or body or any court, domestic or foreign, having jurisdiction over the Company or any of its
properties, or (B) any agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the properties of the Company is subject. Except where it would not have a Material Adverse Effect, the Company (i) is
not in violation of any statute, rule or regulation applicable to the Company or its assets, (ii) is not in violation of any judgment, order or decree applicable to the Company or its assets, and (iii) is not in breach or violation of any agreement,

incomplete. 
  
 Tax Matters. The Company has timely
prepared and filed all tax returns required to have been filed by the Company with all appropriate governmental agencies and timely paid all taxes owed by it, in each case taking into account permitted extensions. The charges, accruals and reserves
on the books of the Company in respect of taxes for all fiscal periods are adequate, and there are no unpaid assessments against the Company nor, to the knowledge of the Company, any basis for the assessment of any additional taxes, penalties or
interest for any fiscal period or audits by any federal, state or local taxing authority. All taxes and other assessments and levies that the Company is required to withhold or to collect for payment have been duly withheld and collected and paid to
the proper governmental entity or third party when due. There are no tax liens or claims pending or threatened against the Company or any of its respective assets or property. There are no outstanding tax sharing agreements or other such
arrangements between the Company and any other corporation or entity. 
  
 Title to Properties and Securities. Except as disclosed in the SEC Filings, the Company has good and marketable title to all real properties and all other properties and assets owned by it, in each case free from liens, encumbrances
and defects that would 
  

 8 

 materially affect the value thereof or materially interfere with the use made or currently planned to be made thereof by
them; and except as disclosed in the SEC Filings, the Company holds any leased real or personal property under valid and enforceable leases with no exceptions that would materially interfere with the use made or currently planned to be made thereof
by them. 
  
 Certificates, Authorities and Permits. The
Company possesses adequate certificates, authorities or permits issued by appropriate governmental agencies or bodies necessary to conduct the business now operated by it and has not received any notice of proceedings relating to the revocation or
modification of any such certificate, authority or permit that, if determined adversely to the Company, would individually or in the aggregate have a Material Adverse Effect. 
  
 No Labor Disputes. No material labor dispute with the employees of the Company exists or, to the knowledge of the
Company, is imminent.

or presently employed by it, and presently contemplated to be operated by it, and the Company has not received any notice of infringement of or conflict with asserted rights of others with respect to any Intellectual Property Rights except as
disclosed in the SEC Filings. None of the Company’s Intellectual Property Rights have expired or terminated, or are expected to expire or terminate within three years from the date of this Agreement, except those the expiration or termination
of which would not cause a Material Adverse Effect. To the Company’s knowledge, the Company’s patents and other Intellectual Property Rights and the present activities of the Company do not infringe any patent, copyright, trademark, trade
name or other proprietary rights of any third party where such infringement may cause a Material Adverse Effect on the Company. There is no claim, action or proceeding being made or brought against, or to the Company’s knowledge, being
threatened against, the Company regarding its Intellectual Property Rights, and the Company is unaware of any facts or circumstances which might give rise to any of the foregoing. The Company has no knowledge of the material infringement of its
Intellectual Property Rights by third parties and has no reason to believe that any of its Intellectual Property Rights is unenforceable, and the Company is unaware of any facts or circumstances which might give rise to any of the foregoing. The

any section hereof and no written information furnished by the Company to the Purchasers or any authorized representative of the Purchasers, pursuant to the Agreements or in connection therewith, contains any untrue statement of a material fact or

 Representations and Warranties of the Purchaser. Each of the Purchasers hereby severally, and not jointly, represents
and warrants to the Company as to itself only that: 
  
 Organization and Existence. The Purchaser is a validly existing corporation, partnership or limited liability company and has all requisite corporate, partnership or limited liability company power and authority to invest in the

 Authorization.

creditors’ rights generally. 
  
 Purchase Entirely for Own
Account. The Securities to be received by the Purchaser hereunder will be acquired for the Purchaser’s own account, not as nominee or agent, and not with a view to the resale or distribution of any part thereof in violation of

received and read the SEC Filings filed via EDGAR at least five days prior to the date hereof. Neither such inquiries nor any other due diligence investigation conducted by the Purchaser shall modify, amend or affect the Purchaser’s right to
rely on the Company’s representations and warranties contained in this Agreement or made pursuant to this Agreement. 
  
 Restricted Securities. The Purchaser understands that the Securities are characterized as “restricted securities” under the U.S. 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, applicable state laws and applicable regulations such securities may be resold without registration under
the 1933 Act only in certain limited circumstances. 
  
 Legends. It is understood that, until registration for resale pursuant to the Registration Rights Agreement or until sales under Rule 144 are permitted, certificates evidencing the Securities may bear one or all of the following
legends or legends substantially similar thereto: 
  
 “THIS
SECURITY HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER ANY STATE SECURITIES LAWS, IN RELIANCE UPON EXEMPTIONS FROM REGISTRATION FOR NON-PUBLIC OFFERINGS. THIS SECURITY MAY NOT BE SOLD OR
TRANSFERRED UNLESS IT IS REGISTERED UNDER THE ACT AND UNDER APPLICABLE STATE SECURITIES LAWS OR UNLESS THERE IS AN AVAILABLE EXEMPTION FROM, OR SUCH SALE OR TRANSFER IS IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES
ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS, AS EVIDENCED BY AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER.” 
  
 If required by the authorities of any state in connection with the issuance of sale of the Securities, the legend required by such state authority.

  

 12 

 Upon registration for resale pursuant to the Registration Rights Agreement, and for so long as (and at
all times as) such Registration Statement remains effective, or upon Rule 144(k) under the 1933 Act becoming available, the Company shall promptly cause certificates evidencing the Underlying Shares and Warrant Shares previously issued to be
replaced with certificates which do not bear such restrictive legends, and all Underlying Shares and Warrant Shares subsequently issued shall not bear such restrictive legends. The Company shall not place any restrictive legend on certificates
evidencing the Underlying Shares and Warrant Shares subsequently issued or impose any stop transfer restriction thereon, unless prior to such Rule 144(k) becoming available the relevant Registration Statement subsequently becomes withdrawn or
otherwise ceases to be effective, provided that any such restrictive legends or stop transfer restrictions shall be removed upon the earlier of such Registration Statement subsequently becoming effective or such Rule 144(k) becoming available.

  
 Accredited Investor. The Purchaser is an
“accredited investor” as defined in Rule 501(a) of Regulation D, as amended, under the 1933 Act. 
  
 No General Solicitation. The Purchaser did not learn of the investment in the Securities as a result of any public advertising or general
solicitation. 
  
 Closing Documents. The parties
acknowledge and agree that part of the inducement for the Purchasers to enter into this Agreement is the Company’s execution and delivery of the Registration Rights Agreement. The parties acknowledge and agree that on or prior to the Closing,
the Registration Rights Agreement will be duly executed and delivered by the parties thereto. 
  
 Covenants and Agreements of the Company. 
  
 19.9% Cap; Rule 144. 
  
 19.9% Cap. In the event that at any time the Company would be obligated to issue an amount of shares upon conversion of, as payment for dividends on, for redemption of, and otherwise pursuant to, the Preferred Shares, or upon
exercise of the Warrants, which, when aggregated with all shares of Common Stock issued to the Purchasers hereunder (including under the Certificate and Warrants and including to other purchasers of Preferred Shares), would constitute a breach of
the Company’s obligations under the rules or regulations of the American Stock Exchange as they apply to the Company, or any other principal securities exchange or market (“Principal Market”) upon which the Common Stock is or becomes
traded (the “Cap Regulations”), the Company shall not be obligated to issue any such shares of Common Stock to the extent such shares are in excess of the maximum permissible amount (“Maximum Common Stock Issuance”) under such
Cap Regulations (“Excess Shares”). Each holder of Preferred Shares shall be entitled to receive the number of Underlying Shares, together with its Warrant Shares under the Warrant held by it, equal to such holder’s pro rata share of
the Maximum Common Stock Issuance (based upon its aggregate Purchase Price under the Purchase Agreement). Once a holder has received its total pro rata share upon conversion 
  

 13 

 of its Preferred Shares and exercise of its Warrants, and if the Company shall not have complied with its obligations to
obtain the stockholder approval described below by the date set forth below, it shall have the right to compel the Company to redeem its remaining Preferred Shares and Warrants as set forth below. If a holder has converted and exercised all of its
Preferred Shares and Warrants, but has not depleted the total number of pro rata shares of the Maximum Common Stock Issuance allocated to it hereunder, its remaining pro rata shares shall be reallocated amongst the other holders still holding
Preferred Shares and Warrants on a pro rata basis. If at any point in time and from time to time (each a “Trigger Date”) the number of shares of Common Stock issued pursuant to conversion of the Preferred Shares and exercise of the
Warrants, together with the number of shares of Common Stock that would then be issuable by the Company upon conversion of all the Preferred Shares and exercise of all the Warrants then outstanding, would exceed the Maximum Common Stock Issuance but
for this Section, then the Company shall, at the Company’s election, either (A) promptly call a shareholders meeting to obtain shareholder approval for the issuance of shares of Common Stock hereunder in excess of the Maximum Common Stock
Issuance, which such shareholder approval shall be obtained within 60 days following the Trigger Date, or (B) purchase from the holders of Preferred Shares and Warrants on a pro rata basis such number of Preferred Shares and number of Warrants which
cannot be converted or exercised due to such Maximum Common Stock Issuance limitation at a redemption price equal to (x) for the Preferred Shares, 100% of such Liquidation Value (as defined in the Certificate), and (y) for the Warrants, the number
of Excess Shares underlying the Warrant multiplied by the positive difference, if any, of the closing sale price on the American Stock Exchange as of the Trigger Date minus the Warrant Price (as defined in the Warrants). Such redemption price shall
be paid within five (5) trading days after a Trigger Date if this clause (B) is elected. The Company shall make such election with three (3) days following the Trigger Date by giving written notice to all holders of Preferred Shares and Warrants. If
the Company fails to timely make such election, or elects clause (A) but then fails to obtain such shareholder approval within 60 days following the Trigger Date, then the Company shall purchase such Preferred Shares and Warrants which cannot be
converted or exercised within five (5) trading days following any such failure. Only shares of Common Stock acquired pursuant to this Agreement (including Underlying Shares and Warrant Shares) will be included in determining whether the limitation
contained herein would be exceeded for purposes of this Section 7.1(a). 
  
 Rule 144. The Company agrees that, for purposes of determining the holding period under Rule 144 of the 1933 Act for Underlying Shares issued upon conversion of the Preferred Shares, the holding period of such Underlying Shares shall
be tacked to the holding period of the Preferred Shares. The Company agrees to make publicly available on a timely basis the information necessary to enable Rule 144 under the 1933 Act to be available for resale.

 Right of the Purchasers to Participate in Future Transactions. For the two-year period commencing
on the Closing Date, The Tail Wind Fund Ltd. and Solomon Strategic Holdings, Inc. will have a right to participate in any sales of any of the Company’s securities in a capital raising transaction on the terms and conditions set forth in this
Section 7.3. During such period, the Company shall give 36 hours advance written notice to such Purchasers prior to any non-public offer or sale of any of the Company’s equity securities or any securities convertible into or exchangeable or
exercisable for such securities in a capital raising transaction by providing to such Purchasers a comprehensive term sheet containing all significant business terms of such a proposed transaction. Such Purchasers shall have the right (pro rata in
accordance with such Purchasers’ purchase price for the Preferred Shares) to participate in such transaction by purchasing in such transaction an amount of the identical securities issued in such transaction equal to up to 15% of the aggregate
amount of such securities issued to such Purchasers and such other investors together for the same consideration and on the same terms and conditions as such third-party sale. If, subsequent to the Company giving notice to such Purchasers hereunder
but prior to each of such Purchasers exercising its rights hereunder, the terms and conditions of the third-party sale are changed from that disclosed in the comprehensive term sheet provided to such Purchaser, the Company shall be required to
provide a new notice to such Purchaser hereunder and such Purchasers shall have the right to exercise their rights to purchase the identical securities in such transaction on such changed terms and conditions as provided hereunder. The rights and
obligations of this Section 7.3 shall in no way diminish the other rights of the Purchasers pursuant to this Section 7. Notwithstanding anything to the contrary contained herein, the number of shares of Common Stock that may be acquired by any
Purchaser pursuant to any capital raising transaction as described in this Section 7.3 shall not exceed a number that, when added to the total number of shares of Common Stock deemed beneficially owned by such Purchaser (other than by virtue of the
ownership of securities or rights to acquire securities that have limitations on the Purchaser’s right to convert, exercise or purchase similar to the limitation set forth herein), together with all shares of Common Stock deemed beneficially
owned by the Purchaser’s “affiliates” (as defined in Rule 144 of the 1933 Act) that would be aggregated for purposes of determining whether a group under Section 13(d) of the 1934 Act, exists, would exceed 9.9% of the total issued and
outstanding shares of the Common Stock. 
  
 Opinion of
Counsel. On or prior to the Closing Date, the Company will deliver to the Purchasers the opinions of legal counsel to the Company substantially in the form and substance attached hereto as Exhibit D. 
  
 Reservation of Common Stock issuable upon Conversion of Preferred Shares
and Exercise of Warrants. The Company hereby agrees at all times to reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of providing for the full conversion of Preferred Shares (including
payment of accrued dividends thereon and redemption thereof) and the exercise of the Warrants, such number of shares of Common Stock as shall from time to time equal the number of shares sufficient to permit the full conversion of Preferred Shares
(including payment of accrued dividends thereon and redemption thereof) in accordance with the terms of the Certificate 
  

 15 

 and to permit the full exercise of the Warrants in accordance with the terms of the Warrants. All calculations pursuant
to this paragraph shall be made without regard to restrictions on beneficial ownership. 
  
 Reports. For so long as the Purchasers beneficially own the Preferred Shares or Warrants, the Company will furnish to the Purchasers the following reports, each of which shall be provided to the Purchasers by
air mail or reputable international courier (within one week of filing with the SEC, in the case of SEC filings), to the extent not filed on and available at that time via EDGAR: 
  
 Quarterly Reports. As soon as available and in any event within 45 days after the end of each fiscal
quarter of the Company, the Company’s quarterly report on Form 10-Q or, in the absence of such report, consolidated balance sheets of the Company as at the end of such period and the related consolidated statements of operations,
stockholders’ equity and cash flows for such period and for the portion of the Company’s fiscal year ended on the last day of such quarter, all in reasonable detail and certified by the Company to have been prepared in accordance with
generally accepted accounting principles, subject to year-end and audit adjustments. 
  
 Annual Reports. As soon as available and in any event within 90 days after the end of each fiscal year of the Company, the
Company’s Form 10-K or, in the absence of a Form 10-K, consolidated balance sheets of the Company as at the end of such fiscal year and the related consolidated statements of earnings, stockholders’ equity and cash flows for such year, all
in reasonable detail and accompanied by the report on such consolidated financial statements of an independent certified public accountant selected by the Company and reasonably satisfactory to the Purchaser. 
  
 Securities Filings. As promptly as practicable and in
any event within five days after the same are issued or filed, copies of (i) all notices, proxy statements, financial statements, reports and documents as the Company shall send or make available generally to its stockholders or to financial
analysts, and (ii) all periodic and special reports, documents and registration statements (other than on Form S-8) which the Company furnishes or files, or, to the extent also delivered to the Company, any officer or director of the Company (in
such person’s capacity as such) furnishes or files with the SEC. 
  
 Other Information. Such other information relating to the Company as from time to time may reasonably be requested by any Purchaser provided the Company produces such information in its ordinary course of
business, and further provided that the Company, solely in its own discretion, determines that such information is not confidential 
  

 16 

 in nature and disclosure to the Purchaser would not be harmful to the Company or violate any rules or
regulations of the SEC or the American Stock Exchange. 
  
 Press Releases. Any press release or other publicity concerning this Agreement or the transactions contemplated by this Agreement shall be submitted to the Purchasers for comment at least two (2) business days prior to issuance,
unless the release is required to be issued within a shorter period of time by law or pursuant to the rules of the American Stock Exchange or another national securities exchange or market. The Company shall issue a press release concerning the fact
and material terms of this Agreement within three business days of the Closing, provided that in lieu thereof the Company may file a Form 8-K concerning the fact and material terms of this Agreement within five business days of the Closing
(attaching such Agreements as applicable). 
  
 No Conflicting
Agreements. The Company will not take any action, enter into any agreement or make any commitment that would conflict or interfere in any material respect with the obligations to the Purchasers under the Agreements. 
  
 Insurance. For so long as any Purchaser beneficially owns any of the
Securities, the Company shall have in full force and effect (a) insurance reasonably believed by the Company to be adequate on all assets and activities, covering property damage and loss of income by fire or other casualty, and (b) insurance
reasonably believed to be adequate protection against all liabilities, claims and risks against which it is customary for companies similarly situated as the Company to insure. 
  
 Compliance with Laws. So long as the Purchasers beneficially own any Securities, the Company will use reasonable
efforts to comply with all applicable laws, rules, regulations, orders and decrees of all governmental authorities, except to the extent non-compliance (in one instance or in the aggregate) would not have a Material Adverse Effect. 
  
 Listing of Underlying Shares and Related Matters. The Company hereby
agrees, promptly following the Closing of the transactions contemplated by this Agreement, to take such action to cause the Underlying Shares and the Warrant Shares to be listed on the American Stock Exchange as promptly as possible but no later
than the effective date of the registration contemplated by the Registration Rights Agreement. The Company further agrees that if the Company applies to have its Common Stock or other securities traded on any other principal stock exchange or
market, it will include in such application the Underlying Shares and Warrant Shares and will take such other action as is necessary to cause such Common Stock to be so listed. For so long as any Preferred Shares remain outstanding, the Company will
take all action necessary to continue the listing and trading of its Common Stock on the AMEX or another Approved Market, and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of
such exchange or market, as applicable, to ensure the continued eligibility for trading of the Underlying Shares and the Warrant Shares thereon. 
  

 17 

 Corporate Existence. So long as any Preferred Shares or Warrants remain outstanding, the Company
shall maintain its corporate existence, except in the event of a merger, consolidation or sale of all or substantially all of the Company’s assets so long as the surviving or successor entity in such transaction (a) assumes the Company’s
obligations hereunder and under the agreements and instruments entered into in connection herewith, regardless of whether or not the Company would have had a sufficient number of shares of Common Stock authorized and available for issuance in order
to fulfill its obligations hereunder and effect the conversion (including payment on) and exercise in full of all Preferred Shares and Warrants outstanding as of the date of such transaction; (b) has no legal, contractual or other restrictions on
its ability to perform the obligations of the Company hereunder and under the agreements and instruments entered into in connection herewith; and (c)(i) is a publicly traded corporation whose common stock and the shares of capital stock issuable
upon conversion and exercise of the Preferred Shares and Warrants are (or would be upon issuance thereof) listed for trading on an Approved Market or (ii) if not such a publicly traded corporation, then the buyer agrees that it will, at the election
of the Purchasers, purchase such Purchasers’ Securities at a price equal to the greater of (a) 120% of the Purchase Price of such Securities or (b) the fair market value of such Securities on an as-converted and as-exercised basis based on the
closing price immediately preceding such transaction or the redemption date, whichever is greater. 
  
 Survival. All representations, warranties, covenants and agreements contained in this Agreement shall be deemed to be representations, warranties,
covenants and agreements as of the date hereof and shall survive the execution and delivery of this Agreement and terminate upon expiration of the applicable statute of limitations. 
  
 Miscellaneous. 
  
 Successors and Assigns. This Agreement may not be assigned by the Company without the prior written consent of the holders of at least 75% of the
outstanding Preferred Shares, which consent may not be unreasonably withheld or delayed. This Agreement may not be assigned by any Purchaser without the prior written consent of the Company, which consent may not be unreasonably withheld or delayed,
except that without the prior written consent of the Company, but after notice duly given, a Purchaser may assign its rights and delegate its duties hereunder in whole or in part to an Affiliate or to any Person to which such Purchaser has
transferred or assigned all or part of its Preferred Shares or Warrants in accordance with the terms of the Certificate and Warrants, provided in each case that such Affiliate, transferee or assignee acknowledges in writing to the Company that the
representations and warranties contained in Section 5 hereof shall apply to such Affiliate, transferee or assignee. The terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and
assigns of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations, or liabilities under or by reason
of this Agreement, except as expressly provided in this Agreement. 
  

 18 

 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one and the same instrument. 
  
 Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

connection herewith, except that the Company shall pay to Tail Wind Advisory and Management Ltd. a non-refundable sum equal to $40,000 as and for legal and due diligence expenses incurred in connection herewith, half of which amount has been
previously paid. The Company shall pay all fees and expenses of any placement agents or finders in connection with the transactions contemplated by this Agreement pursuant to a separate agreement between such parties. 
  
 Amendments and Waivers. Any term of this Agreement may be amended and
the observance of any term of this Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and holders of 75% of the Preferred Shares, provided,
however, that any such amendment or waiver effected in accordance with this paragraph shall be binding upon each holder of any Securities purchased under this Agreement at the time outstanding, each future holder of all such securities, and the
Company. 
  
 Severability. If one or more provisions of
this Agreement are held to be unenforceable under applicable law, such provision shall be excluded from this 
  

 19 

 Agreement and the balance of this Agreement shall be interpreted as if such provision were so excluded and shall be
enforceable in accordance with its terms. 
  
 Entire
Agreement. This Agreement, including the Exhibits and Schedules hereto, and the Registration Rights Agreement, the Certificate and Warrants and other documents contemplated hereby constitute the entire agreement among the parties hereof with
respect to the subject matter 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. 
  
 Further Assurances. The parties shall execute and deliver all such
further instruments and documents and take all such other actions as may reasonably be required to carry out the transactions contemplated hereby and to evidence the fulfillment of the agreements herein contained. 
  
 Applicable Law. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York without regard to principles of conflicts of laws. 
  
 Remedies. 
  
 The Purchasers shall be entitled to specific performance of the Company’s obligations under the Agreements. 
  
 The Company on the one hand, and each Purchaser severally and not jointly on
the other hand, shall indemnify the other and hold it harmless from any loss, cost, expense or fees (including attorneys’ fees and expenses) arising out of any breach of any representation, warranty, covenant or agreement in any of the
Agreements, or arising out of the enforcement of this Section 9.11. 
  
 Jurisdiction. The parties hereby agree that all actions or proceedings arising directly or indirectly from or in connection with this Agreement or the other Agreements shall be litigated only in the Supreme Court of the State of New
York or the United States District Court for the Southern District of New York located in New York County, New York. The parties consent to the jurisdiction and venue of the foregoing courts and consent that any process or notice of motion or other
application to either of said courts or a judge thereof may be served inside or outside the State of New York or the Southern District of New York by registered mail, return receipt requested, directed to the party being served at its address set
forth in this Agreement (and service so made shall be deemed complete three (3) days after the same has been posted as aforesaid) or by personal service or in such other manner as may be permissible under the rules of said courts. The Company and
the Purchasers hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement or the other Agreements. 
  
 1.17. Like Treatment of Purchasers and Holders. Neither the Company nor any of its affiliates shall, directly or indirectly, pay or cause to be
paid any 
  

 20 

 consideration (immediate or contingent), whether by way of interest, fee, payment for the redemption, conversion or
exercise of the Securities, or otherwise, to any Purchaser or holder of Securities, for or as an inducement to, or in connection with the solicitation of, any consent, waiver or amendment of any terms or provisions of the Agreements, unless such
consideration is required to be paid to all Purchasers or holders of Securities bound by such consent, waiver or amendment. The Company shall not, directly or indirectly, redeem any Securities unless such offer of redemption is made pro rata to all
Purchasers and holders of Securities on identical terms. For clarification purposes, this provision constitutes a separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, 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. 
  
 1.18. Actions of Purchasers. The obligations of each Purchaser hereunder and under the documents contemplated hereby are several and not joint with
the obligations of any other Purchaser, and no Purchaser shall in any way be responsible for the performance of the obligations of any other Purchaser under any such document. Nothing contained herein or in any other document contemplated hereby,
and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute any of 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 hereby or thereby. Each Purchaser confirms that it has independently participated in the negotiation of the transaction contemplated hereby
with the advice of its own counsel and advisors. 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 any other document contemplated
hereby, and it shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. Notwithstanding anything herein to the contrary, the actions and obligations of the Purchasers hereunder shall at
all times be considered several and not joint, and the Purchasers are not, under any circumstances, agreeing to act jointly with respect to the Securities or any of their actions or obligations under the Agreements, and shall not constitute a
“group” under the 1934 Act. Each Purchaser acknowledges that no other Purchaser has acted as agent for such Purchaser in connection with making its investment hereunder and that no other Purchaser will be acting as agent of such Purchaser
in connection with monitoring its investment hereunder. 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 Agreements, and it
shall not be necessary for any other Purchaser to be joined as an additional party in any proceeding for such purpose. The Company has elected to provide all Purchasers with the same terms and Agreements for the convenience of the Company and not
because it was required or requested to do so by the Purchasers.
