This SERIES B PREFERRED STOCK PURCHASE AGREEMENT (this “Agreement”), dated March 25, 2013, is entered into by and among Heat Biologics, Inc., a Delaware corporation (the “Company”), and the several undersigned purchasers (individually, a “Purchaser” and collectively, the “Purchasers”). Certain capitalized terms used herein are defined in Section 6.19 of this Agreement.

RECITALS

The Company wishes to issue and sell to the Purchasers up to an aggregate of: (a) 1,891,404 shares (the “Series B-1 Shares”) of the Company’s authorized but unissued shares of Series B-1 Preferred Stock, par value $0.0001 per share; (b) 433,130 shares (the “Series B-2 Shares”, and together, with the Series B-1 Shares to be sold hereunder, the “Preferred Shares”) of the Company’s authorized but unissued shares of Series B-2 Preferred Stock, par value $0.0001 per share (the Series B-1 Shares and the Series B-2 Shares, together, are sometimes hereinafter referred to as the “Series B Preferred Stock”); and (c) 216,565 warrants exercisable into Series B-1 Shares (the “Warrants”).

The Purchasers, severally and not jointly, wish to purchase the Preferred Shares on the terms and subject to the conditions set forth in this Agreement.

AGREEMENT

NOW, THEREFORE, in consideration of the premises, the respective representations, warranties and agreements set forth in this Agreement, and other good and valuable consideration the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the parties hereby agree as follows:

ARTICLE I.

THE PREFERRED SHARES

Section 1.1

COMMITMENTS TO PURCHASE; PURCHASE PRICE; ISSUANCE, SALE AND DELIVERY OF PREFERRED SHARES; EFFECT OF FAILURE TO HONOR COMMITMENTS. Each Purchaser hereby commits and agrees to purchase from the Company the total number of Preferred Shares set forth opposite the name of such Purchaser under the heading “Number of Preferred Shares to be Purchased” on the form of Schedule 1 hereto (the “Purchase Commitment”), in one or more tranches upon fulfillment of the terms set forth in Section 1.3 of this Agreement. Each Purchaser shall complete a Schedule 1 and submit such completed Schedule 1 to the Company along with such Purchaser’s signature page to this Agreement. Once a Purchaser has delivered a completed Schedule 1 to the Company, such Purchaser shall not be entitled to amend or modify the terms of such Schedule 1. Within twenty (20) calendar days following the Initial Closing (defined below) the Company shall deliver a completed Schedule 1 showing all of the Purchasers’ commitments to Purchase Series B-1 Preferred and Series B-2 Preferred as of such date. The Purchase Commitment made by each Purchaser shall specify the number and dollar value of Series B-1 Shares and the number and dollar value of Series B-2 Shares to be purchased by such Purchaser. The purchase price per Series B-1 Share shall be TWO DOLLARS AND SIXTY-SEVEN CENTS ($2.67) per Series B-1 Share, and the purchase price per Series B-2 Share shall be FIVE DOLLARS AND NO CENTS ($5.00) per Series B-2 Share. Not less than thirty percent (30%) of the total aggregate dollar amount of each Purchaser’s Purchase Commitment must be allocated to the purchase of Series B-2 Shares (the “Minimum Series B-2 Threshold”), provided that, each Purchaser shall have the option, but not the obligation, to allocate a greater relative proportion, up to one hundred percent (100%) of such Purchaser’s Purchase Commitment, toward the purchase of Series B-2 Shares. The number of Series B-2 Shares committed to be purchased by each Purchaser hereunder shall hereinafter be referred to as the “B-2 Commitment” of each such

Purchaser, and such Purchaser’s B-2 Commitment may not be changed after the first sale of Preferred Shares occurring hereunder. For every two (2) Series B-2 Shares that a Purchaser commits to purchase pursuant to such Purchaser’s B-2 Commitment, the Company will issue one (1) Warrant exercisable into one (1) Series B-1 Share. At the Initial Closing (as defined in Section 1.3 hereof), on the terms and subject to the conditions of this Agreement, the Company shall issue and sell to each Purchaser, and each Purchaser shall, severally and not jointly, purchase from the Company, that number of Series B-1 Shares set forth opposite the name of such Purchaser under the heading “Number of Preferred Shares to be Purchased” on such Purchaser’s completed Schedule 1. The purchase and sale of the Series B-2 Shares, and the issuance of the Warrants, shall occur at the Second Closing (as defined in Section 1.3 hereof) and shall be held within five (5) business days of receipt by each such Purchaser of notification by the Company that the Company has received a $16,750,000 tranche of funding from XXXX. In the event that a Purchaser who purchases Series B-1 Shares does not purchase all of its respective B-2 Commitment in the Second Closing (a “Defaulting Purchaser”), then: (a) such Defaulting Purchaser shall not be entitled to purchase any Series B-2 Shares in the Second Closing, and all Series B-2 Shares comprising such Defaulting Purchaser’s B-2 Commitment shall be considered “Forfeited B-2 Shares” hereunder, and (b) (i) all Warrants allocated to such Defaulting Purchaser and (ii) a number of Series B-1 Shares previously purchased by such Defaulting Purchaser having an aggregate value equal to such Defaulting Purchaser’s B-2 Commitment (assuming a per share value of $2.67 for Series B-1 Shares and a per share value of $5.00 for Series B-2 Shares) shall be automatically forfeited without payment on the Second Closing and returned to the Company (the “Forfeited B-1 Shares and Warrants”). As an example of the foregoing, if a Purchaser committed to invest $1,000,000 to purchase Preferred Shares, allocating seventy percent (70%) of such amount ($700,000) to the purchase of Series B-1 Shares, and the remaining thirty percent (30%) of such amount ($300,000) to the purchase of Series B-2 Shares (thereby meeting the Minimum Series B-2 Threshold requirement), and subsequently paid $700,000 to acquire Series B-1 Shares at the Initial Closing, but thereafter failed to purchase all of such Purchaser’s B-2 Commitment at the Second Closing, then in such event, such Purchaser would forfeit all of such Purchaser’s right to acquire Warrants at the Second Closing, along with a number of Series B-1 Shares equal in value to such Purchaser’s B-2 Commitment of $300,000 assuming a price per share for Series B-1 Shares of $2.67, or 112,359.55 Series B-1 Shares (computed as $300,000 divided by $2.67). As a consequence, all such Warrants and B-1 Shares would become “Forfeited B-1 Shares and Warrants”; all Series B-2 Shares that such Purchaser had originally committed to purchase would become “Forfeited B-2 Shares”; and such investor would become a “Defaulting Purchaser” as such terms are defined above. Each Purchaser who purchased its respective B-2 Commitment on the Second Closing (each, a “Non-Defaulting Purchaser”) will be entitled to purchase its B-2 Proportionate Share (defined below) of each Defaulting Purchaser’s Forfeited B-2 Shares. Within five (5) calendar days following the Second Closing, the Company shall provide written notice to each Non-Defaulting Purchaser of any Forfeited B-2 Shares available for purchase. Within five (5) calendar days following delivery of such notice, each Non-Defaulting Purchaser desiring to purchase any of the Forfeited B-2 Shares (a “Participating Shortfall Purchaser”) must deliver written notice to the Company stating the maximum number of Forfeited B-2 Shares that such Participating Shortfall Purchaser desires to purchase, including the number of Forfeited B-2 Shares that such Participating Shortfall Purchaser would purchase if one or more other Non-Defaulting Purchaser does not elect to purchase the full amount of its respective B-2 Proportionate Share of such Forfeited B-2 Shares (the “Shortfall Funding”). The parties will agree to consummate the Shortfall Funding and the purchase and sale of the Forfeited B-2 Shares within thirty (30) calendar days after the Second Closing Date (the “Default Purchase Period”). In the event of an oversubscription for Forfeited B-2 Shares, such oversubscribed-to Forfeited B-2 Shares shall be allocated to each respective Participating Shortfall Purchaser that offered to purchase oversubscribed-to Forfeited B-2 Shares on a pro rata basis in proportion to a fraction equal to the total number of Series B Preferred Stock owned by each such Participating Shortfall Purchaser immediately following the Second Closing (but without taking into account any Shortfall Funding by such Purchaser), over the total number of shares of Series B Preferred Stock held by all of the Participating Shortfall Purchasers that agreed to purchase oversubscribed-to

Forfeited B-2 Shares immediately following the Second Closing (but without taking into account any Shortfall Funding by all Participating Shortfall Purchasers and, in each case, excluding any Series B-1 Shares issuable upon exercise of the Warrants) (each, a “B-2 Proportionate Share”). Promptly following the expiration of the Default Purchase Period, all Forfeited B-1 Shares and Warrants shall be transferred to the Participating Shortfall Purchasers, without additional payment, in proportion to their respective B-1 Proportionate Share (defined below) multiplied by the total number of Forfeited B-1 Shares and Warrants. The “B-1 Proportionate Share” of a Participating Shortfall Purchaser, solely for purposes of determining the allocation of Forfeited B-1 Shares and Warrants, shall be computed as a quotient of a fraction, the numerator of which is the total dollar amount invested by such Participating Shortfall Purchaser as of the expiration of the Default Purchase Period to purchase Forfeited B-2 Shares and as a result of such Participating Shortfall Purchaser’s participation in the Shortfall Funding, and the denominator of which is the total combined dollar value of all of the unsatisfied B-2 Commitments as of the Second Closing. For the avoidance of doubt, the sale and issuance of Preferred Shares in connection with the Shortfall Funding shall not be deemed to constitute an “Additional Closing” as defined hereunder but shall be deemed to be a part of the Second Closing (as defined below).

Section 1.2

ISSUANCE, SALE AND DELIVERY OF ADDITIONAL PREFERRED SHARES. Following the Second Closing, provided that a majority in interest of the then holders of Series B Preferred Stock approve of the sale of any Additional Shares (as defined in Section 1.4 hereof) in their sole discretion, at each Additional Closing (as defined in Section 1.4 hereof), on the terms and subject to the conditions of this Agreement, the Company shall sell to each Additional Purchaser (as defined in Section 1.4 hereof), and each Additional Purchaser shall, severally and not jointly, purchase from the Company, a percentage of the number of Additional Shares set forth opposite the name of such Additional Purchaser under the heading “Number of Preferred Shares to be Purchased” on each Purchaser’s completed Schedule 1.

Section 1.3

CLOSINGS. The Initial Closing, Second Closing and Additional Closings shall take place at such locations, dates and times as may be agreed upon between the Company and the Purchasers (such closings being called, respectively, the “Initial Closing”, the “Second Closing” and the “Additional Closing” (each, a “Closing” and, collectively, the “Closings”) and such date and time being called, as appropriate, the “Initial Closing Date”, the “Second Closing Date” or the “Additional Closing Date”) (each, a “Closing Date” and, collectively, the “Closing Dates”)). At each of the Initial Closing, Second Closing and Additional Closing, the Company shall issue and deliver to each Purchaser a stock certificate or certificates in definitive form, registered in the name of such Purchaser representing the number of the applicable series of Preferred Shares being purchased by such Purchaser pursuant to the terms hereof at the Initial, Second or Additional Closing, as applicable. At the Second Closing, the Company shall issue and deliver the Warrants to the Purchasers. The Second Closing must occur on or before the first anniversary of the First Closing, or such other date agreed upon by the holders of not less than a majority in interest of the outstanding shares of Series B-1 Preferred issued upon the First Closing (the “Majority Series B-1”). The Majority Series B-1 may waive, in its sole discretion, the XXXX funding requirement as a condition to the Second Closing. In the event that the Second Closing does not occur, then any Warrants issued in connection with commitments to purchase Series B-2 Preferred made at the First Closing shall be automatically terminated. As payment in full for the Preferred Shares being purchased by it under this Agreement, and against delivery of the stock certificate or certificates therefor as aforesaid, on the Initial Closing Date, Second Closing Date or Additional Closing Date, each Purchaser shall pay to the Company, by wire transfer to the Company as set forth in Schedule 1.3 hereto or by such other method as may be reasonably acceptable to the Company, immediately available funds in the amount equal to the product of (i) in the case of the purchase of Series B-1 Preferred Shares at the Initial Closing, (a) $2.67 and (b) the number of Series B-1 Preferred Shares being purchased by such Purchaser at the Initial Closing; and (ii) in the case of the purchase of Series B-2 Preferred Shares at the Second Closing or any Additional Closing, (x) $5.00 and (y) the number of Series B-2 Preferred Shares being purchased by such Purchaser at such Second Closing or Additional Closing. Such amounts shall be paid to the account of the Company as shall have been designated in writing a reasonable time in advance to the Purchaser by the Company.

Section 1.4

ADDITIONAL CLOSINGS.

(a)

At any time and from time to time following the Second Closing Date, but on or prior to one hundred eighty (180) calendar days following the Second Closing Date, the Company may sell up to an additional 500,000 Series B-2 Shares (such shares being referred to as the “Additional Shares”) to such Persons (individually, an “Additional Purchaser,” and collectively, the “Additional Purchasers”), on the same terms and at the same purchase price per share as under the Second Closing (i.e., Five Dollars ($5.00) per Series B-2 Share); provided that a majority in interest of the then holders of Series B Preferred Stock so approve of the sale of any Additional Shares in their sole discretion. For the avoidance of doubt, no Warrants shall be issued to any Additional Purchasers in any Additional Closing. All such sales shall be made subject to the terms and conditions set forth in this Agreement, and in reliance on the representations and warranties set forth in this Agreement. At each Additional Closing, the Company shall issue and deliver to each Additional Purchaser a stock certificate or certificates in definitive form, registered in the name of such Additional Purchaser, representing the number of Additional Shares being purchased by it at such Additional Closing. As payment in full for the Additional Shares being purchased by it under this Agreement, and against delivery of the stock certificate or certificates therefor as aforesaid, on the Additional Closing Date, each Additional Purchaser shall pay to the Company by wire transfer as set forth in Schedule 1.3 hereto or by such other method as may be reasonably acceptable to the Company in immediately available funds such amount as shall be equal to the product of the number of Series B-2 Shares being sold at such closing and $5.00. Such amounts shall be paid to the account of the Company as shall have been designated in writing a reasonable time in advance to the Additional Purchasers by the Company.

(b)

In connection with the sale of Additional Shares to Additional Purchasers, each such Additional Purchaser shall execute and deliver a counterpart signature page to this Agreement and a completed Schedule 1 for such Additional Purchaser which shall indicate that such Additional Purchaser is then only purchasing Series B-2 Shares. In addition, each such Additional Purchaser shall execute a form of joinder to each of the other Transaction Documents (as such term is defined in Section 6.19 hereof). Following each such Additional Closing, the Company shall provide to any Purchaser who requests it an updated copy of Schedule 1. Upon the sale of Additional Shares, any Additional Purchaser shall be deemed a “Purchaser” for all purposes hereunder, and such additional shares shall be deemed “Series B-2 Shares” for all purposes hereunder.

Section 1.5

ACCEPTANCE OF PURCHASE COMMITMENTS. The Purchasers acknowledge and agree that the purchase and sale of Preferred Shares hereunder is made subject to the condition that the Company shall have the right to accept a Purchaser’s Purchaser Commitment and offer to purchase Preferred Shares, in full or in part, or the Company may reject any such Purchaser’s Purchaser Commitment and offer to purchase Preferred Shares, and the Company shall have no obligation to accept any Purchase Commitment or offer to purchase Preferred Shares in the order received or at all. If any Purchaser Commitment or offer to purchase Preferred Shares is rejected, in whole or in part, the Company will return promptly to the Purchaser the unaccepted funds previously delivered to the Company, if any, and this Agreement shall only be effective as between the Company and the Purchaser to the extent that such Purchaser’s Purchaser Commitment is partially accepted. If the Company accepts Purchaser’s offer to purchase Preferred Shares in part, the Purchaser’s Purchaser Commitment hereunder and the number of Preferred Shares issued to Subscriber will be adjusted accordingly. Notwithstanding the foregoing, the Company may not reject part of a Purchaser’s Purchaser Commitment in such a manner as to change the relative ratio of Series B-1 Shares and Series B-2 Shares to be purchased by such Purchaser from the ratio set forth in such Purchaser’s Schedule 1.

ARTICLE II.

Section 2.5

AUTHORIZED CAPITAL STOCK.

(a)

The Company’s authorized capital stock consists of 8,212,500 shares of Preferred Stock, par value $0.0001 per share (the “Preferred Stock”), of which 112,500 shares have been designated Series 1 Preferred Stock; 2,000,000 shares have been designated Series A Preferred Stock; 4,100,000 shares have been designated Series B-1 Preferred Stock; 2,000,000 shares have been designated Series B-2 Preferred Stock and 50,000,000 shares of Common Stock. Immediately prior to the Initial Closing, 4,219,781 shares of Common Stock, 112,500 shares of Series 1 Preferred Stock and [1,863,128] shares of Series A Preferred Stock will be validly issued and outstanding and will be fully paid and nonassessable. In addition, immediately prior to the applicable Closing, not more than 114,908 shares of Common Stock will be reserved for issuance upon conversion of Series 1 Preferred Stock, not more than 1,863,128 shares of Common Stock will be reserved for issuance upon conversion of Series A Preferred Stock and not more than 1,489,564 shares of Common Stock will be reserved for issuance upon exercise of outstanding options, warrants or other securities exchangeable for or convertible into Common Stock. The stockholders of record and holders of subscriptions, warrants, options, convertible securities, and other rights (contingent or other) to purchase or otherwise acquire equity securities of the Company, and the number of shares of Common Stock and the number of such subscriptions, warrants, options, convertible securities, and other such rights held by each are as set forth in Schedule 2.5 hereto. The designations, powers, preferences, rights, qualifications, limitations and restrictions in respect of each class and series of the Company’s authorized capital stock are as set forth in the Charter, and all such designations, powers, preferences, rights, qualifications, limitations and restrictions are valid, binding and enforceable and in accordance with all applicable laws. Except as set forth in Schedule 2.5 hereto: (i) no Person owns of record or is known to the Company to beneficially own any share of the Company’s capital stock, (ii) no subscription, warrant, option, convertible security, or other right (contingent or other) to purchase or otherwise acquire equity securities of the Company is authorized or outstanding and (iii) there is no commitment by the Company to issue shares, subscriptions, warrants, options, convertible or exchangeable securities, or other such rights or to distribute to holders of any of its equity securities any evidence of indebtedness or asset, other than the Warrants to be issued hereunder.

Except as set forth in Schedule 2.5 hereto or as may be provided under

the terms of the Warrants to be issued hereunder, no stock plan, stock purchase, stock option or other agreement or understanding between the Company and any holder of any equity securities of the Company or rights to purchase equity securities of the Company provides for acceleration or other changes in the vesting provisions or other terms of such securities, as the result of any merger, sale of stock or assets, change in control or other similar transaction by the Company.

The Conversion Shares (assuming that all of the Preferred Shares are issued at the Closing other than the additional 2,500,000 shares that may be issued if a majority in interest of the then holders of Series B Preferred Stock so approve in their sole discretion) shall constitute, at the time of the Initial Closing, not less than 23% of the Company’s outstanding capital stock, calculated on a Fully-Diluted Basis (as defined in Section 6.19 hereof). All of the outstanding securities of the Company were issued in compliance with all applicable federal and state securities laws.

Consummation of the transactions contemplated by this Agreement and the other Transaction Documents or by any other agreement, understanding or commitment (contingent or otherwise) to which the Company is a party or by which it is otherwise bound will not have the effect of limiting the Company’s ability to use any such net operating losses in full to offset such taxable income. The Company has withheld or collected from each payment made to each of its employees, the amount of all taxes (including, but not limited to, federal income taxes, Federal Insurance Contribution Act taxes and Federal Unemployment Tax Act taxes) required to be withheld or collected therefrom, and has paid the same to the proper tax receiving officers or authorized depositories.

All contributions required to be made under the terms of any Benefit Plan have been timely made or have been reflected on the Financial Statements.

REGISTRATION RIGHTS. Except as set forth in Schedule 2.30 and except for the rights granted under the Investors Rights Agreement, no Person has demand or other rights to cause the Company to file any registration statement under the Securities Act relating to any securities of the Company or any right to participate in any such registration statement, including, without limitation, piggyback registration rights.

Section 2.31

Section 2.32

NON-DISCLOSURE, NON-SOLICITATION AND PROPRIETARY INFORMATION AND INVENTIONS AGREEMENT. Each employee, officer, director, consultant, advisor, agent and representative of the Company has entered into and executed a Employee Non-Disclosure, Non-Solicitation and Proprietary Information and Inventions Agreement or Non-Employee Non-Disclosure, Non-Solicitation and Proprietary Information and Inventions Agreement, as the case may be, substantially in the forms of Exhibit B (collectively, the “Non-Disclosure, Non-Solicitation and Proprietary Information and Inventions Agreement”), or an employment or consulting agreement containing substantially similar terms, and such agreements are in full force and effect. The Company has previously made available to Purchasers’ counsel copies of forms of all material invention assignment and confidentiality agreements or employment or consulting agreements used by the Company that contain terms similar to the Non-Disclosure, Non-Solicitation and Proprietary Information and Inventions Agreement. The Company has no Knowledge that any of its employees, officers, directors, consultants, advisors, agents and representatives is in violation of such agreements, and the Company will use its best efforts to prevent any such violation. In addition, to the Company’s Knowledge, no current or former employee, officer, director, consultant, advisor, agent, or representative of the Company has excluded works or inventions made prior to his or her employment or consulting relationship with the Company from his or her assignment of inventions pursuant to his or her Non-Disclosure, Non-Solicitation and Proprietary Information and Inventions Agreement.

Section 2.33

DISCLOSURE. The Company has disclosed to the Purchasers all facts material to the Company’s business, operations, assets, liabilities, prospects, properties, condition (financial or otherwise) and results of operations. Neither this Agreement, any Schedule or Exhibit to this Agreement, the Business Plan of the Company, dated March 12, 2013, as delivered to the Purchasers, (the “Business Plan”), nor any other statements, documents or certificates made or delivered in connection herewith or therewith contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained herein and therein not misleading in light of the circumstances under which such statements were made. None of the statements, documents, certificates or other items prepared or supplied by the Company with respect to the transactions contemplated hereby contains an untrue statement of a material fact or omits to state a material fact necessary to make the statements contained therein not misleading in light of the circumstances under which such statements were made. There is no fact that the Company has not disclosed to the Purchasers and their counsel in writing and of which the Company is aware which has resulted in, or could result in, a Material Adverse Change. The financial projections and other estimates contained in the Business Plan were prepared by the Company based on the Company’s experience in the industry and on assumptions of fact and opinion as to future events which the Company, at the date of the issuance of the Business Plan, believed to be reasonable and which the Company currently believes are reasonable. As of the date hereof, no facts have come to the Company’s attention that would, in its opinion, require the Company to revise or amplify the assumptions underlying such projections and other estimates or the conclusions derived therefrom.

The Company shall also pay all stamp and other taxes and duties levied in connection with the issuance of the Preferred Shares or, upon conversion thereof, the Conversion Shares, or the Series B-1 Shares issuable upon exercise of the Warrants.

Section 6.2

SURVIVAL OF AGREEMENTS. All covenants, agreements, representations and warranties made in any of the Transaction Documents or any certificate or instrument delivered to the Purchasers pursuant to or in connection with any of the Transaction Documents shall survive the execution and delivery of all of the Transaction Documents, the issuance, sale and delivery of the Preferred Shares, the issuance and delivery of the Conversion Shares, and the issuance and delivery of the Warrants and all statements contained in any certificate or other instrument delivered by the Company hereunder or thereunder or in connection herewith or therewith shall be deemed to constitute representations and warranties made by the Company.

Section 6.3

ENTIRE AGREEMENT. This Agreement, together with the Schedules hereto and any certificates, documents, instruments and writings that are delivered pursuant hereto, constitutes the entire agreement and understanding of the parties in respect of the subject matter hereof and supersedes all prior understandings, agreements or representations by or among the parties, written or oral, to the extent they relate in any way to the subject matter hereof. There are no third party beneficiaries having rights under or with respect to this Agreement.

Section 6.4

ASSIGNMENT; BINDING EFFECT. No party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other parties; provided, however, that without the consent of any other party hereto the rights of a Purchaser hereunder are assignable (a) to an affiliate of such Purchaser, or (b) to any other Purchaser or (b) to an assignee or transferee who acquires at least 100,000 shares, as adjusted for stock dividend, stock splits, combinations, recapitalizations and similar events, of the Preferred Shares purchased by a Purchaser. All of the terms, agreements, covenants, representations, warranties and conditions of this Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties and their respective successors and permitted assigns, whether so expressed or not. Without limiting the generality of the foregoing, all representations, covenants and agreements benefiting the Purchasers, their respective successors and permitted assigns shall inure to their benefit whether such Persons are holding Preferred Shares, Conversion Shares, or Warrants (and Series B-1 Shares issuable upon exercise thereof) as the case may be. Nothing in this Agreement shall create or be deemed to create any third-party beneficiary rights in any Person not a party to this Agreement except as provided below. Whether or not any express assignment has been made, the provisions of this Agreement which are for the benefit of any Purchaser as a purchaser or holder of Preferred Shares (or any securities pursuant to which such Preferred Shares may be converted or exercised into) are also for the benefit of and enforceable by any subsequent holder of such Preferred Shares who acquires at least 100,000 shares, as adjusted for stock dividend, stock splits, combinations, recapitalizations and similar events, to the same extent they would have been enforceable by such Purchaser. Upon any permitted assignment, the references in this Agreement to such Purchaser shall also apply to any such assignee unless the context otherwise requires.

Section 6.7

HEADINGS. The article and section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation of this Agreement.

Section 6.8

GOVERNING LAW. This Agreement will be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to any choice of law principles.

Section 6.9

AMENDMENTS. This Agreement may not be amended or modified without the written consent of the Company and the holders of at least 66 2/3% of the outstanding shares of Common Stock issued or issuable upon conversion of the Preferred Shares.

Section 6.10

EXTENSIONS; WAIVERS. Any party may, for itself only, (a) extend the time for the performance of any of the obligations of any other party under this Agreement, (b) waive any inaccuracies in the representations and warranties of any other party contained herein or in any document delivered pursuant hereto and (c) waive compliance with any of the agreements or conditions for the benefit of such party contained herein. Any such extension or waiver will be valid only if set forth in a writing signed by the party to be bound thereby. No waiver by any party of any default, misrepresentation or breach of warranty or covenant hereunder, whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent such occurrence. Neither the failure nor any delay on the part of any party to exercise any right or remedy under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right or remedy preclude any other or further exercise of the same or of any other right or remedy.

Section 6.11

SEVERABILITY. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party or to any circumstance, is judicially determined not to be enforceable in accordance with its terms, the parties agree that the court judicially making such determination may modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words or phrases, and in its modified form, such provision will then be enforceable and will be enforced.

Section 6.12

COUNTERPARTS; EFFECTIVENESS. This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. This Agreement will become effective when one or more counterparts have been signed by each of the parties and delivered to the other parties. For purposes of determining whether a party has signed this Agreement or any document contemplated hereby or any amendment or waiver hereof, only a handwritten original signature on a paper document or a facsimile copy of such a handwritten original signature shall constitute a signature, notwithstanding any law relating to or enabling the creation, execution or delivery of any contract or signature by electronic means.

Section 6.13

CONSTRUCTION. This Agreement has been freely and fairly negotiated among the parties. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring any party because of the authorship of any provision of this Agreement. Any reference to any law will be deemed also to refer to such law as amended and all rules and regulations promulgated thereunder, unless the context requires otherwise. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties intend that each representation, warranty, and covenant contained herein will have independent significance. If any party has breached any covenant contained herein in any respect, the fact that there exists another covenant relating to the same subject matter (regardless of the relative levels of specificity) which the party has not breached will not detract from or mitigate the fact that the party is in breach of the first covenant. Time is of the essence in the performance of this Agreement.

Section 6.14

ATTORNEYS’ FEES. If any dispute among any parties arises in connection with this Agreement, the prevailing party in the resolution of such dispute in any action or proceeding will be entitled to an order awarding full recovery of reasonable attorneys’ fees and expenses, costs and expenses (including experts’ fees and expenses and the costs of enforcing this Section 6.15) incurred in connection therewith, including court costs, from the non-prevailing party.

Section 6.15

BROKERAGE. Each party hereto will indemnify and hold harmless the others against and in respect of any claim for brokerage or other commissions relative to this Agreement or to the transactions contemplated hereby, based in any way on agreements, arrangements or understandings made or claimed to have been made by such party with any third party.

Section 6.16

ADJUSTMENTS FOR STOCK SPLITS, ETC. Wherever in this Agreement there is a reference to a specific number of shares of the Company’s capital stock of any class or series, then, upon the occurrence of any subdivision, combination or stock dividend of such class or series of stock, the specific number of shares so referenced in this Agreement will automatically be proportionally adjusted to reflect the effect of such subdivision, combination or stock dividend on the outstanding shares of such class or series of stock.

Section 6.17

AGGREGATION OF STOCK. All shares of Common Stock owned or acquired by any Purchaser or its Affiliated entities or persons (assuming full conversion, exchange and exercise of all convertible, exchangeable and exercisable securities into Common Stock) shall be aggregated together for the purpose of determining the availability of any right under this Agreement.

Section 6.18

EXCULPATION AMONG PURCHASERS.
