to Section 4(a)(2) of the Securities Act; 
 WHEREAS, each Purchaser desires to commit to purchase up to the aggregate principal amount
of Notes as set forth on the signature page hereof (such amount, with respect to each Purchaser, its “Commitment Amount”, and the aggregate of all Commitment Amounts for all Purchasers that are parties to this Agreement at any given
time, the “Aggregate Commitment Amount”) and will receive corresponding Warrants on the terms and conditions set forth in this Agreement; and 

WHEREAS, concurrently with the execution of this Agreement, (a) the Company and U.S. Bank National Association (the “Collateral
Agent”) are entering into a Security Agreement, of even date herewith (the “Security Agreement”), and (b) the Collateral Agent and the Purchasers are entering into a Collateral Agency Agreement, of even date herewith
(the “Collateral Agency Agreement”). 
 NOW, THEREFORE, in consideration of the promises and the mutual representations and
covenants hereinafter set forth, the parties hereto do hereby agree as follows: 
  

	I.	OFFERING; SUBSCRIPTION 

 1.1 The Offering. Subject to the terms and conditions of
this Agreement, the Company will offer to sell to persons who qualify as “accredited investors” as defined in Rule 501(a) of Regulation D, pursuant to an exemption provided by Regulation D or pursuant to Section 4(a)(2)
of the Securities Act (the “Offering”), Notes, which will be sold in minimum principal denominations of $250,000 (or such other principal amount determined in the mutual discretion of the Placement Agent and the Company), and in
addition, in order to induce Purchasers to purchase Notes, the Purchasers will receive Warrants to purchase the number of 







 
shares of Common Stock determined in accordance with Section 1.4(c), which will be exercisable for five years from the applicable Closing Date (as defined below) in which the Warrant is
issued, and will otherwise be in the form attached hereto as Exhibit B. The Notes, the Warrants and the shares of Common Stock issuable upon exercise of the Warrants (the “Warrant Shares”) are, individually and
collectively, referred to herein as the “Securities”. 
 1.2 Subscription; Commitment. 

(a) Subject to the terms and conditions of this Agreement, each Purchaser, severally and not jointly, hereby subscribes for and irrevocably
commits to purchase from the Company up to its Commitment Amount of aggregate principal amount of Notes and will receive corresponding Warrants (the “Subscriptions”) and the Company, subject to Section 1.3 below, agrees to sell
such Notes and issue Warrants to the Purchaser. Each Purchaser must complete and return a duly executed, unaltered, and completed Confidential Purchaser Questionnaire in the form of Schedule A attached hereto prior to or concurrently with the
execution of this Agreement. 
 (b) The Company shall have the right, at any time on or before the 60th day after the Initial Closing (as
defined below), to enter into additional Subscriptions with prospective Purchasers approved by the Company and the Placement Agent, until the Aggregate Commitment Amount equals the Maximum Commitment Amount. The Company shall have the right to
accept or reject Subscriptions after the date hereof in its sole discretion. Upon execution and delivery of the relevant signature pages to this Agreement and any other Transaction Documents to which the Purchasers are party, such prospective
Purchasers shall become parties to, and be bound by, this Agreement and the Transaction Documents, without the need for an amendment to any of this Agreement or the other Transaction Documents, and the Aggregate Commitment Amount shall be
automatically increased by the applicable Commitment Amount of each such Purchaser. 
 1.3 Tranches; Closings. The purchase and sale
of Notes and issuance of the Warrants in connection therewith shall take place in one or more tranches (each, a “Tranche”) as determined by the Company pursuant to the terms and conditions of this Agreement. The initial Tranche will
be drawn in two separate closings, the first of which (the “Initial Closing”) shall occur on the date of this Agreement, or on such other date agreed upon by the Company and the Placement Agent (the “Initial Closing
Date”), and the second of which (the “Second Closing”) shall take place on the date that Subscriptions totaling in the aggregate the Maximum Commitment Amount are received (including Subscriptions with respect to which
Notes were purchased and Warrants were issued in the Initial Closing). After the Initial Closing Date and prior to the second anniversary of the Initial Closing Date (the “Draw Termination Date”), the Company may, in its sole and
absolute discretion, schedule one or more subsequent closings for the purchase and sale of Tranches of Notes and having aggregate principal amount of not less than one third (1/3) of the Aggregate Commitment Amount per Tranche, together with
corresponding Warrants (each, a “Subsequent Closing”), until the entire Aggregate Commitment Amount of Notes has been sold. The Company shall schedule a Subsequent Closing by sending a written notice in substantially the form
attached hereto as Exhibit C to the Placement Agent and to each Purchaser (a “Tranche Request”) at least 15 calendar days prior to the date of the Subsequent Closing, or a shorter period otherwise agreed upon by the Company
and the 

  
 2 








 
Placement Agent. The Initial Closing, the Second Closing and each Subsequent Closing are each sometimes referred to herein as a “Closing,” and the date on which each such Closing
occurs is sometimes referred to herein as a “Closing Date.” The Company may in its sole and absolute discretion decide not to schedule any Subsequent Closings and the Company is under no commitment to sell and issue all or any of
the Notes and Warrants available for sale and issuance pursuant to this Agreement after the Initial Closing. 
 1.4 Actions to be Taken
in Connection with the Closing of each Tranche. 
 (a) The parties hereto acknowledge and agree that an aggregate amount of one third
(1/3) of the Aggregate Commitment Amount for Subscriptions received as of the date hereof will be sold and issued in the Initial Closing, and the Placement Agent has notified each Purchaser participating in the Initial Closing prior to the
execution of this Agreement of such Purchaser’s Closing Amount (as defined below) with respect to the Initial Closing. Further, the parties hereto acknowledge and agree that an aggregate amount of one third (1/3) of the Commitment Amounts
for Subscriptions received with respect to Purchasers that did not purchase Notes and receive Warrants in the Initial Closing will be sold and issued to such Purchasers in the Second Closing, and the Placement Agent has notified each such Purchaser
prior to their execution of this Agreement of such Purchaser’s Closing Amount with respect to the Second Closing. Thereafter, promptly after receipt of any Tranche Request for any Subsequent Closing, the Placement Agent will forward the Tranche
Request to each Purchaser. For purposes of this Agreement, (i) “Closing Amount” means, with respect to each Purchaser, the Purchaser’s Pro Rata Share of the Aggregate Purchase Price applicable to such Closing,
(ii) “Aggregate Purchase Price” means the aggregate principal amount of Notes to be purchased by all Purchasers at a Closing, as determined by the Company subject to the terms and conditions of this Agreement, and
(iii) “Pro Rata Share” means, with respect to each Purchaser, the quotient obtained by dividing (A) such Purchaser’s Commitment Amount, by (B) the aggregate Commitment Amounts of all Purchasers hereunder. 

(b) At each Closing, the Company will sell to each Purchaser and each Purchaser will purchase from the Company, a Note having a principal
amount equal to the Purchaser’s Closing Amount for the applicable Tranche, and in connection therewith, will issue each Purchaser a Warrant to purchase a number of shares of Common Stock equal to the product obtained by multiplying the
Applicable Percentage (as defined below) by the quotient obtained by dividing (x) the Purchaser’s Closing Amount applicable to such Tranche, by (y) the Market Value (as defined below) applicable to such Tranche. The Warrants shall
have an exercise price equal to 115% of the Market Value applicable to the Tranche in which they are issued. 
 (c) For purposes of this
Agreement, (i) “Applicable Percentage” means (A) 25% for the first Tranche (which, for the avoidance of doubt, applies to Warrants issued in the Initial Closing and the Second Closing), (B) 25% for the second Tranche,
and (C) 20% for each subsequent Tranche, provided, however, that for any Tranche for which the Company delivers a Tranche Request to the Placement Agent after the date that is 12 months following the Initial Closing Date, the Applicable
Percentage shall be 35%; and (ii) “Market Value” means (A) for Initial Closing, the VWAP of the Common Stock for the five Trading Days immediately preceding the Initial Closing Date, (B) for Second Closing, the VWAP
of the Common Stock for the five Trading Days immediately preceding the date of the Second Closing, 

  
 3 








 
and (C) for each subsequent Tranche, the lesser of (x) the VWAP of the Common Stock for the five Trading Days immediately preceding the Initial Closing Date, and (y) the VWAP of
the Common Stock for the five Trading Days immediately preceding the applicable Closing Date for such Tranche. For purposes of this Agreement, the “VWAP” of the Common Stock for any given period, shall be the volume weighted average
sale price of the Company’s Common Stock for such period, as reported by Bloomberg Financial Markets. For purposes of this Agreement, “Trading Day” means (i) a day on which the Common Stock is listed or quoted and traded
on its Principal Trading Market (other than the OTC Bulletin Board), or (ii) if the Common Stock is not listed on a Trading Market (other than the OTC Bulletin Board), a day on which the Common Stock is traded in the over-the-counter market
(including the OTC Bulletin Board), as reported by the OTC Bulletin Board, or (iii) if the Common Stock is not quoted on any Trading Market, a day on which the Common Stock is quoted in the over-the-counter market as reported by OTC Link LLC
(formerly known as Pink Sheets LLC) (or any similar organization or agency succeeding to its functions of reporting prices); provided, that in the event that the Common Stock is not listed or quoted as set forth in (i), (ii) and
(iii) hereof, then Trading Day shall mean a Business Day (as defined below). “Trading Market” means whichever of the New York Stock Exchange, the NYSE MKT (formerly the American Stock Exchange), the NASDAQ Global Select Market,
the NASDAQ Global Market, the NASDAQ Capital Market or the OTC Bulletin Board on which the Common Stock is listed or quoted for trading on the date in question. “Principal Trading Market” means the Trading Market on which the Common
Stock is primarily listed on and quoted for trading, which, as of the date of this Agreement and the Initial Closing Date, shall be the OTC Bulletin Board. 

(d) Upon compliance with all conditions to the applicable Closing, the institution designated by the Placement Agent, with notice to the
Company, shall release the proceeds of the Closing to the Company, less fees and expenses due to the Placement Agent. 
 1.5 Payment
Mechanics. No later than one Business Day prior to each Closing, each Purchaser will deposit its Closing Amount into escrow with an institution designated by the Placement Agent pursuant to the instructions in the applicable Tranche Request. The
Closing Amount is payable by wire transfer or such other method as determined by the Placement Agent. Purchasers paying by wire transfer should direct such wire transfer to the account specified on the applicable Tranche Request. 

1.6 Delivery of Documents. The documents evidencing the Notes purchased, and the Warrants issued, at the Closing will be delivered by
the Company to the Placement Agent on the applicable Closing Date. 
  

	II.	REPRESENTATIONS, WARRANTIES AND COVENANTS OF PURCHASERS 

 Each Purchaser hereby
represents, warrants and covenants to the Company, severally and not jointly, as follows: 
 2.1 The Purchaser recognizes and acknowledges
that the purchase of the Securities involves a high degree of risk including, but not limited to, the following: (i) an investment in the Company is highly speculative, and only Purchasers who can afford the loss of


  
 4 








 
their entire investment should consider investing in the Company and the Securities; (ii) the Purchaser may not be able to liquidate his/her/its investment; (iii) transferability of the
Securities is extremely limited; (iv) in the event of a disposition of the Securities, the Purchaser could sustain the loss of his/her/its entire investment; and (v) the Company has not paid any dividends on its Common Stock since
inception and does not anticipate the payment of dividends in the foreseeable future. 
 2.2 The Purchaser is an “accredited
investor” as such term is defined in Rule 501(a) of Regulation D as indicated by the Purchaser’s responses to the questions contained in Schedule A hereof, which responses are true and correct as of the date hereof and
shall be true and correct as of each Closing, and the Purchaser is able to bear the economic risk of an investment in the Company for an indefinite period of time. If the Purchaser is a natural person, the Purchaser has reached the age of majority
in the state or other jurisdiction in which the Purchaser resides. 
 2.3(a) The Purchaser hereby acknowledges and represents that
(i) the Purchaser is knowledgeable, sophisticated and has experience in making, and is qualified to make, decisions with respect to investments representing an investment decision like that involved in the purchase of the Securities hereunder
and has prior investment experience, including investment in securities which are non-listed, unregistered and/or not traded on a national securities exchange; (ii) the Purchaser recognizes that the Company’s financial condition has been
and continues to be weak and the Company’s auditors have included explanatory paragraphs in the Company’s audited financial statements for the fiscal year ended 2013 indicating substantial doubt as to the Company’s ability to continue
as a going concern; and (iii) Purchaser recognizes that the market price of the Common Stock of the Company has been and continues to be volatile, and Purchaser has carefully evaluated the risks of an investment in the Securities. 

(b) The Purchaser hereby acknowledges that the Purchaser has read the Offering Materials (as defined below), including the sections titled
“Risk Factors” set forth therein, and understands that (i) an investment in the Securities is a highly speculative investment, and in the event of a liquidation, bankruptcy or insolvency of the Company, it is highly unlikely that the
Company will have sufficient assets to repay all the Notes in full; (ii) the collateral securing the Company’s obligations under the Notes consists primarily of the Company’s intellectual property, the value of which is tied to the
Company as a going concern and such collateral will generate substantially less value to secured creditors in a liquidation than the operating value of the Company; and (iii) delays, costs and expenses incurred in connection with any
enforcement of the Collateral (as defined in the Security Agreement) will further erode the amount of funds available, if any, to repay the holders of Notes. 

2.4 The Purchaser hereby acknowledges that he/she/it has received and carefully reviewed this Agreement and the offering materials provided to
the Purchasers, as amended or supplemented, including all documents attached thereto or incorporated by reference therein (the “Offering Materials”), including the following documents filed by the Company with the Securities and
Exchange Commission (the “SEC” or the “Commission”): Annual Report on Form 10-K for the year ended December 31, 2013, filed March 31, 2014; Amendment No. 1 to Annual Report on Form 10-K/A
for the year end December 31, 2013, filed April 30, 2014;

has been furnished by the Company during the course of this transaction with all information regarding the Company which the Purchaser, its investment advisor, attorney and/or accountant has requested or desired to know or which is otherwise
relevant to an investment decision, has been afforded the opportunity to ask questions of, and receive answers from, duly authorized officers or other representatives of the Company concerning the terms and conditions of the Offering, and has
received any additional information which the Purchaser or its advisors or agents has requested. 
 2.5 (a) The Purchaser has relied solely
upon the information in the Offering Materials or provided by the Company in making the decision to invest in the Securities. The Purchaser is familiar with and understands the terms of the Offering, including the rights to which the Purchaser is
entitled under this Agreement. In evaluating the suitability of an investment in the Company, the Purchaser has not relied upon any representation or other information (whether oral or written) from the Company, or any agent, employee or Affiliate
(as defined below) of the Company other than as set forth in the Offering Materials, in this Agreement or resulting from Purchaser’s own independent investigation. Purchaser understands and acknowledges that nothing in this Agreement, the
Offering Materials or any other materials provided to Purchaser in connection with the Subscription for the Securities constitutes investment, tax or legal advice. To the extent deemed necessary or advisable by Purchaser in his/her/its sole
discretion, the Purchaser has retained, at his/her/its sole expense, and relied upon appropriate professional advice regarding the investment, tax and legal merits and consequences of this Agreement and its purchase of the Securities hereunder. 

(b) The Purchaser is not purchasing the Securities as a result of any advertisement, article, notice or other communication regarding the
Securities published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general advertisement. 

2.6 The Purchaser hereby acknowledges that neither the Offering nor the Offering Materials has been reviewed, recommended or endorsed by the
SEC or any state securities regulatory authority or other governmental body or agency, since the Offering is intended to be exempt from the registration requirements of Section 5 of the Securities Act pursuant to Regulation D or pursuant to
Section 4(a)(2) of the Securities Act. The Purchaser shall not sell or otherwise transfer the Securities unless such transfer is registered under the Securities Act or unless an exemption from such registration is available. The Purchaser
understands that if required by the laws or regulations or any applicable jurisdictions, the Offering contemplated hereby will be submitted to the appropriate authorities of such state(s) for registration or exemption therefrom and the Offering
contemplated hereby will be specifically subject to the receipt of such registration or exemption. 

  
 6 








 2.7 The Purchaser understands and acknowledges that the Securities have not been registered under
the Securities Act in reliance upon a claimed exemption under the provisions of the Securities Act which depends, in part, upon the Purchaser’s investment intention and the truth and accuracy of, and the Purchaser’s compliance with, the
representations, warranties, acknowledgments and covenants of the Purchaser set forth herein. In this connection, the Purchaser hereby represents that the representations, warranties, acknowledgments and covenants of the Purchaser set forth herein
are true and accurate, the Purchaser will comply with the covenants set forth herein, and the Purchaser is purchasing the Securities for the Purchaser’s own account for investment purposes only and not with a view toward the resale or
distribution to others and has no contract, undertaking, agreement or other arrangement to sell, pledge, assign or otherwise transfer the Securities to any other person. The Purchaser, if an entity, also represents that it was not formed for the
purpose of purchasing the Securities. 
 2.8 The Purchaser understands that the Securities will not be registered or available for sale in
the public markets except as specifically provided herein, and Rule 144 promulgated under the Securities Act (“Rule 144”) requires, among other conditions, a six month holding period prior to the resale (and with respect to
Affiliates of the Company, such resales may only be in limited amounts) of securities acquired in a non-public offering without having to satisfy the registration requirements under the Securities Act. The Purchaser understands and hereby
acknowledges that the Company is under no obligation to register any of the Securities under the Securities Act or any state securities or “blue sky” laws or assist the Purchaser in obtaining an exemption from various registration
requirements, other than as set forth in Article VII herein. 
 2.9 The Purchaser consents to the placement of a legend on any Note,
certificate, warrant or other document evidencing the Securities substantially in one of the forms set forth below, that such Securities have not been registered under the Securities Act or any state securities or “blue sky” laws and
setting forth or referring to the restrictions on transferability and sale thereof contained in this Agreement. The Purchaser is aware that the Company will make a notation in its appropriate records and with its transfer agent with respect to the
restrictions on the transferability of the Securities.

REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT, (B) UNLESS IN ACCORDANCE WITH RULE 144 UNDER THE SECURITIES ACT OR (C) UNLESS PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS OR BLUE SKY LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE COMPANY AND ITS TRANSFER AGENT.” 

2.10 The Purchaser hereby represents that the address of the Purchaser furnished by Purchaser on the signature page hereof is the
Purchaser’s principal residence if Purchaser is an individual or its principal business address if it is a corporation or other entity. 

2.11 The Purchaser represents that (i) the Purchaser has full right, power, authority and capacity (corporate, personal, statutory and
otherwise) to execute, deliver, and perform this Agreement and to purchase the Securities and has taken all action necessary to authorize the execution, delivery and performance of this Agreement; and (ii) this Agreement constitutes the legal,
valid and binding obligation of the Purchaser, enforceable against the Purchaser in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting

 2.12 If the Purchaser is a corporation, partnership, limited liability company, trust, employee benefit plan, individual retirement
account, Keogh Plan, or other entity (i) it is authorized and qualified to become a Purchaser and/or securityholder in the Company and the person signing this Agreement on behalf of such entity has been duly authorized by such entity to do so
and (ii) it is duly organized, validly existing and in good standing under the laws of the jurisdiction of its organization. 
 2.13
The Purchaser acknowledges that if he or she is a Registered Representative of a Financial Industry Regulatory Authority (“FINRA”) member firm, he or she must give such firm the notice required by applicable FINRA rules, receipt of
which must be acknowledged in accordance with such rules. 
 2.14 The Purchaser understands, acknowledges and agrees with the Company that,
except as otherwise set forth herein, the Subscription hereunder is irrevocable by the Purchaser, that, except as required by law, the Purchaser is not entitled to cancel, terminate or revoke this Agreement or any agreements of the Purchaser
hereunder and that this Agreement and such other agreements shall survive the death or disability of the Purchaser and shall be binding upon and inure to the benefit of the parties and their heirs, executors, administrators, successors, legal
representatives and permitted assigns. If the Purchaser is more than one person, the obligations of the Purchaser hereunder shall be joint and several and the agreements, representations, warranties and acknowledgments herein contained shall be
deemed to be made by and be binding upon each such person and his/her heirs, executors, administrators, successors, legal representatives and permitted assigns. 

  
 8 








 2.15 The Purchaser understands, acknowledges and agrees with the Company that the Offering is
intended to be exempt from registration under the Securities Act by virtue of Section 4(a)(2) of the Securities Act and/or the provisions of Regulation D thereunder, which is in part dependent upon the truth, completeness and accuracy of
the statements made by the Purchaser. 
 2.16 The Purchaser understands, acknowledges and agrees with the Company that, there can be no
assurance that the Purchaser will be able to sell or dispose of the Securities. It is understood that in order not to jeopardize the Offering’s exempt status under Section 4(a)(2) of the Securities Act and/or Regulation D, in addition to
any other restrictions on transfer set forth herein or in the Warrants, the Company may, at a minimum, require any transferee to fulfill the Purchaser suitability requirements thereunder and make the representations, warranties and covenants of
Purchaser hereunder. 
 2.17 The Purchaser agrees that during the period from the date that Purchaser was first contacted with respect to
the Offering (the “First Date”) through the date that is 30 days following the Draw Termination Date, the Purchaser will not directly or indirectly, through related parties, affiliates or otherwise sell “short” or
“short against the box” (as those terms are generally understood) any equity security of the Company, and from the First Date through the date that is 30 days following the Draw Termination Date, will not take any action, other than any
action such Purchaser is specifically entitled to take under the Transaction Documents (as defined below), the intent or reasonably foreseeable effect of which is to reduce the trading price of the Common Stock. At no time will the Purchaser take
any action with respect to any equity security of the Company which would violate the Securities Act or the rules and regulations promulgated thereunder. 

2.18 If the Purchaser is purchasing the Securities in a fiduciary capacity for another person or entity, including without limitation a
corporation, partnership, trust or any other entity, the Purchaser has been duly authorized and empowered to execute this Agreement and all other subscription documents, and such other person or entity fulfills all the requirements for purchase of
the shares as such requirements are set forth herein, concurs in the purchase of the Securities and agrees to be bound by the obligations, representations, warranties and covenants contained herein. 

2.19 No authorization, approval, consent or license of any person is required to be obtained for the purchase of the Securities by the
Purchaser, other than as have been obtained and are in full force and effect. The execution and delivery of this Agreement does not, and the consummation of the transactions contemplated hereby will not, result in any violation of or constitute a
default under (i) any Purchaser’s charter, by-laws or other organizational documents, as applicable, (ii) any material agreement or other instrument to which the Purchaser is a party or by which the Purchaser or any of its properties
are bound, or (iii), to the best of the Purchaser’s knowledge, any permit, franchise, judgment, order, decree, statute, rule or regulation to which the Purchaser or any of its businesses or properties is subject, except in the case of clauses
(ii) and (iii) above, for such violations or defaults which would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the ability of such Purchaser to perform its obligations hereunder. 

  
 9 








 2.20 The representations, warranties and agreements of the Purchaser contained herein, in the
Confidential Purchaser Questionnaire and in any other writing delivered in connection with the transactions contemplated hereby shall be true and correct in all respects on and as of each Closing Date as if made on and as of such date and shall
survive the execution and delivery of this Agreement and the purchase of the Securities. Purchaser agrees to notify the Company as promptly as possible of any change in any of the foregoing information until such time as the Purchaser has sold all
of its Securities. 
 2.21 The Purchaser hereby covenants with the Company not to make any sale of the Securities under any registration
statement without effectively causing the prospectus delivery requirement under the Securities Act to be satisfied, and further agrees to comply with reasonable requests of the Company or its transfer agent to provide additional information and

each Subsidiary are validly issued and are fully paid, non-assessable and free of preemptive and similar rights. For purposes hereof, “Subsidiary” shall mean, with respect to any Person (as defined below), any other Person of which
more than fifty percent (50%) of the shares of stock or other interests entitled to vote in the election of directors or comparable Persons performing similar functions (excluding shares or other interests entitled to vote only upon the failure

or by which either the Company is bound or obligating the Company to issue, deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any shares of the capital stock of the Company or obligating the
Company to grant, extend or enter into any such option, warrant, call, right, commitment or agreement. There are no preemptive rights or rights of first refusal or similar rights which are binding on the Company permitting any person to subscribe
for or purchase from the Company shares of its capital stock pursuant to any provision of law, the Company’s Certificate of Incorporation as in effect on the applicable Closing Date (the “Certificate of Incorporation”) or the
Company’s By-laws, as in effect on the applicable Closing Date (the “By-laws”) or by agreement or otherwise. Other than as disclosed in the Offering Materials, there are no securities or instruments (including, without
limitation, any warrants or convertible debentures) containing anti-dilution or similar provisions that will be triggered by the issuance of the Securities as described in this Agreement. Except as provided in the Offering Materials, this Agreement,
or in the engagement letter, dated September 17, 2014, between the Company and the Placement Agent (the “Placement Agent Agreement”), no stockholder of the Company has any right to request or require the Company to register the
sale of any shares owned by such stockholder under the Securities Act. The Company has made available to the Purchasers and the Placement Agent true and correct copies of the Company’s Certificate of Incorporation and the Company’s

applicable Transaction Documents, will be duly and validly issued, fully paid and nonassessable, free and clear of all Liens (as defined below) other than Liens specific to any Purchaser and other than restrictions on transfer provided for in the
Transaction Documents or by applicable law. The Warrant Shares when issued in accordance with the terms of the Transaction Documents, will be validly issued, fully paid and nonassessable, free and clear of all Liens (other than Liens specific to any
Purchaser) and shall not be subject to preemptive or similar rights of stockholders. The Company has reserved from its duly authorized capital stock a sufficient number of shares of Common Stock for issuance of the Warrant Shares issuable under the
Warrants issued in the Initial Closing and will reserve a sufficient number of shares of Common Stock for issuance of the Warrant Shares issuable under the Warrants, if any, issued in the Second Closing and any Subsequent Closing prior to such
Second Closing or Subsequent Closing. For purposes hereof, “Liens” shall mean and include security interests, mortgages, liens, pledges, charges, easements, reservations, restrictions, rights of way, servitudes, options, rights of
first refusal, community property interests, equitable interests, restrictions of any kind and all other encumbrances, whether or not relating to the extension of credit or the borrowing of money. 

3.3 Authorization; Enforceability. The Company has all requisite corporate right, power and authority to enter into this Agreement and
the other Transaction Documents and to consummate the transactions contemplated hereby and thereby. All corporate action on the part of the Company, its directors and stockholders necessary for the authorization, execution, delivery and performance
of this Agreement and the other Transaction Documents by the Company, the authorization, sale, issuance and delivery of the Securities contemplated herein and the performance of the Company’s obligations hereunder has been taken (other than

constitute legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to limitations of public policy or general principals of equity (regardless of whether such enforceability is
considered at law or equity). 
 3.4 No Conflict; Governmental and Other Consents; No Violations. 

(a) The execution, delivery and performance by the Company of the Transaction Documents and the consummation by the Company of the
transactions contemplated thereby will not (i) conflict with or result in the violation of any law, statute, rule, regulation, order, writ, injunction, judgment or decree of any court or governmental authority to or by which the Company or any
Subsidiary is bound, (ii) conflict with or violate any provision of the Certificate of Incorporation or By-laws of the Company or any Subsidiary, or (iii) conflict with, or result in a breach or violation of, any of the terms or provisions

reasonably likely to result in a Material Adverse Effect. 
 (b) No consent, approval, authorization or other order of, or any filing or
registration with, any governmental authority or other third-party is required to be made or obtained by the Company or any Subsidiary in connection with the authorization, execution, delivery and performance of this Agreement and the other
Transaction Documents or with the authorization, issue and sale of the Securities, except such filings as may be required to be made with the Commission, FINRA or with any state or foreign blue sky or securities regulatory authority, which filings
will be made on or prior to the Closing or, for those filings which may be made post-Closing, such filings will be made post-Closing within the time period prescribed for such filings. 

(c) Neither the Company nor any of its Subsidiaries (i) is in default under or in violation of (and no event has occurred that has not
been waived that, with notice or lapse of time or both, would result in a default by the Company or any of its Subsidiaries under), nor has the Company or any of its Subsidiaries received written notice of a claim that it is in default under or that
it is in violation of, any agreement (whether or not such default or violation has been waived), (ii) is in violation of any order of any court, arbitrator or governmental body having jurisdiction over the Company or any of its Subsidiaries or
their properties or assets, or (iii) is in violation of, or in receipt of written notice that it is in violation of, any statute, rule or regulation of any governmental authority applicable to the Company or any of its Subsidiaries, except in
each case set forth in clauses (i), (ii) and (iii) as would not, individually or in the aggregate, have or reasonably be expected to result in a Material Adverse Effect. 

3.5 Litigation. Other than as disclosed in the SEC Reports (as defined below), there is no pending or, to the knowledge of the Company,
threatened legal or governmental proceedings to which the Company is a party which is reasonably expected to result in a Material Adverse Effect. Neither the Company, nor any director or officer thereof (in connection with their service to the
Company), is the subject of any action involving a claim of violation of or liability under federal or state securities laws or a claim of breach of fiduciary duty. To the knowledge of the Company, there is not pending or contemplated, any official
investigation by the Commission involving the Company or any current director or officer of the Company in connection with their service to the Company. The Company has not received any stop order or other order suspending the effectiveness of any
currently effective registration statement filed by the Company under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or the Securities Act. 

3.6 SEC Reports; Financial Statements. The Company has filed all reports, schedules, forms, statements and other documents required to
be filed by it under the Securities Act and the Exchange Act, including pursuant to Section 13(a) or 15(d) of the Exchange Act, for the one-year period preceding the date hereof (the foregoing materials, including the exhibits thereto and
documents incorporated by reference therein, being collectively referred to herein as 

  
 13 








 
the “SEC Reports”) on a timely basis or has received a valid extension of such time of filing and has filed any such SEC Reports prior to the expiration of any such extension.
Except to the extent of any subsequent correction filed prior to the date hereof (and a copy of which has been heretofore provided to the Purchasers), as of their respective dates, the SEC Reports complied in all material respects with the
requirements of the Securities Act and the Exchange Act, as applicable, and the rules and regulations of the Commission promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading. The financial statements of the Company included in the SEC Reports,
as subsequently amended and restated (provided such amendments, if any, have been heretofore provided to the Purchasers), complied in all material respects with applicable accounting requirements and the rules and regulations of the Commission with
respect thereto as in effect at the time of filing. Such financial statements have been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis during the periods involved
(“GAAP”), except as may be otherwise specified in such financial statements or the notes thereto and except that unaudited financial statements may not contain all footnotes required by GAAP, and fairly present in all material
respects the financial position of the Company as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of unaudited statements, to normal, immaterial, year-end audit adjustments.

 3.7 Material Changes. Since the date of the latest audited financial statements included within the SEC Reports, except as
disclosed in the SEC Reports, (i) there has been no event, occurrence or development that has had or would reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect, (ii) the Company has not incurred any

Company’s financial statements pursuant to GAAP or required to be disclosed in filings made with the Commission and (C) expenses incurred in connection with the transactions contemplated hereunder, (iii) the Company has not altered
its method of accounting, (iv) the Company has not declared or made any dividend or distribution of cash or other property to its stockholders or purchased, redeemed or made any agreements to purchase or redeem any shares of its capital stock

securities to any officer, director or Affiliate, except pursuant to existing Company stock purchase or stock option plans. Except for the issuance of the Securities contemplated by this Agreement and the transactions contemplated by the Transaction
Documents, no event, liability or development has occurred or exists with respect to the Company or its Subsidiaries or their respective business, properties, prospects, operations or financial condition, that is required to be disclosed by the
Company under applicable federal securities laws at the time this representation is made that has not been publicly disclosed at least one Trading Day prior to the date that this representation is made. 

3.8 Investment Company. The Company is not, and is not an Affiliate of, and immediately after receipt of payment for the Securities,
will not be or be an Affiliate of an “investment company” within the meaning of such term under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder. 

  
 14 








 3.9 Public Utility Holding Company. The Company is not, and after giving effect to the
offering and sale of the Securities and the application of the proceeds thereof as described in the Offering Materials, will not be, a “holding company,” or a “subsidiary company” of a “holding company,” or an
“affiliate” of a “holding company” or of a “subsidiary company” of a “holding company,” within the meaning of the Public Utility Holding Company Act of 1935, as amended. 

3.10 Use of Proceeds. The Company shall use the net proceeds of the Offering for product development and other general corporate
purposes. 
 3.11 Intellectual Property. 

(a) Section 3.11(a) of the Disclosure Schedule sets forth a list of: 

(i) all United States and foreign patents and patent applications, all United States, state and foreign trademarks, service marks and trade
names for which registrations have been issued or applied for that are owned by or to the knowledge of the Company are subject to an obligation of assignment to the Company, in each case as of the date hereof; and 

(ii) all United States and foreign patents and patent applications, all United States, state and foreign trademarks, service marks and trade
names for which registrations have been issued or applied for that are licensed to the Company as of the date hereof. 
 (b) The Company
and/or its Subsidiaries owns or possesses adequate and, to its knowledge, enforceable rights to use all material patents, patent applications, trademarks, service marks, trade names, logos, corporate names, copyrights, trade secrets, processes, mask
works, licenses, inventions, formulations, technology and know-how and other intangible property currently used in the conduct of its business as described in the Offering Materials (the “Proprietary Rights”). The Company and/or its
Subsidiaries have taken commercially reasonable measures to protect all of the Company’s and such Subsidiary’s Proprietary Rights. Except as disclosed in the SEC Reports, neither the Company nor any of its Subsidiaries has received any
notice of, and there are not any facts known to the Company or any Subsidiary which indicate the existence of (i) any infringement or misappropriation by any third party of any of the Proprietary Rights, which infringement or misappropriation
would reasonably be expected to have a Material Adverse Effect, (ii) any claim by a third party contesting the validity of any of the Proprietary Rights, other than claims that would not reasonably be expected to have a Material Adverse Effect
or (iii) any infringement, misappropriation or violation by the Company or any Subsidiary or, to the Company’s knowledge, any of their employees, of any Proprietary Rights of third parties that would be reasonably expected to have a
Material Adverse Effect. To the Company’s knowledge, no infringement, illicit copying, misappropriation or violation of any intellectual property rights of any third party has occurred by the Company or any of its Subsidiaries with respect to
any products currently being sold by the Company or any 

  
 15 








 
Subsidiary or with respect to any products currently under development by the Company or any Subsidiary or with respect to the conduct of the business of the Company or any Subsidiary as
currently conducted. To the Company’s knowledge, no infringement, illicit copying, misappropriation or violation of any intellectual property rights of any third party will occur by the Company or any of its Subsidiaries as a result of the sale
by the Company or any Subsidiary of any products currently under development by the Company should such products receive the applicable regulatory approval for commercial sale. The Company is not aware that any of its employees, including the
employees of its Subsidiaries, are obligated under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that the Company
believes would materially interfere with the use of the employee’s best efforts to promote the interests of the Company and/or its Subsidiaries or that would conflict with the business of the Company and/or its Subsidiaries as currently
conducted. To the Company’s knowledge, neither the execution and delivery of this Agreement, nor the carrying on of the business of the Company and its Subsidiaries by the employees of the Company and its Subsidiaries, nor the conduct of the
business of the Company and its Subsidiaries, as currently conducted, will conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument under which any such
employee is now obligated. 
 3.12 Private Offering. Neither the Company nor, to the Company’s knowledge, any Person acting on
the Company’s behalf has sold, offered to sell or solicited any offer to buy the Securities by means of any form of general solicitation or advertising. Neither the Company, nor, to the Company’s knowledge, any of its Affiliates or any
Person acting on the Company’s behalf has, directly or indirectly, at any time within the past six months, made any offer or sale of any security or solicitation of any offer to buy any security under circumstances that would eliminate the
availability of the exemption from registration under Regulation D under the Securities Act in connection with the offer and sale of the Securities as contemplated hereby. 

3.13 Transactions With Officers and Directors. Except as set forth in the Offering Materials, none of the officers or directors of the
Company is presently a party to any transaction with the Company (other than for services as officers or directors), including any contract, agreement or other arrangement providing for the furnishing of services to or by, providing for rental of
real or personal property to or from, or otherwise requiring payments to or from any officer or director, or to the knowledge of the Company, any entity in which any officer or director has a substantial interest or is an officer, director, trustee
or partner, in each case in excess of $60,000 other than (i) for payment of salary, consulting fees, board or board committee compensation for services rendered, (ii) reimbursement for expenses incurred on behalf of the Company,
(iii) for other employee benefits, including stock option agreements under any stock option plan of the Company, and (iv) the payment of fees to the Placement Agent and the Company’s other obligations pursuant to the Placement Agent
Agreement (it being acknowledged that Timothy McInerney, a director and Chairman of the Board of the Company, is a principal of the Placement Agent and Mr. McInerney is a Purchaser hereunder and is therefore a party to this Agreement and
certain of the other Transaction Documents).

 3.14 Sarbanes-Oxley; Disclosure Controls. The Company is in compliance in all material
respects with all provisions of the Sarbanes-Oxley Act of 2002 which are applicable to it. The Company has established disclosure controls and procedures (as such term is defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) for the
Company and designed such disclosure controls and procedures to ensure that information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the
time periods specified in the Commission’s rules and forms. The Company’s certifying officers have evaluated the effectiveness of the Company’s disclosure controls and procedures as of the end covered by the period for the
Company’s most recently filed periodic report under the Exchange Act (the “Evaluation Date”). The Company disclosed in its most recently filed periodic report under the Exchange Act the conclusions of the certifying officers
about the effectiveness of the disclosure controls and procedures based on their evaluations as of the Evaluation Date. Since the Evaluation Date, there have been no significant changes in the Company’s disclosure controls and procedures. 

3.15 Internal Controls. The Company maintains effective “internal control over financial reporting” (as defined in Rule
13a-15 under the Exchange Act) and a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorizations,
(ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with GAAP and to maintain asset and liability accountability, (iii) access to assets or incurrence of liabilities is permitted only in
accordance with management’s general or specific authorization, and (iv) the recorded accountability for assets and liabilities is compared with the existing assets and liabilities at reasonable intervals and appropriate action is taken
with respect to any differences. Since the end of the Company’s most recent audited fiscal year, there has been no material weakness or significant deficiency in the Company’s internal control over financial reporting (whether or not
remediated) and since such date there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial
reporting. 
 3.16 Certain Fees. Neither the Company nor any of its officers has retained any broker, financial advisor or
consultant, finder, placement agent, investment banker, bank or other Person (collectively, “Intermediary”) with respect to the transactions contemplated by this Agreement other than the Placement Agent, and the Company shall
indemnify and hold harmless the Purchasers from any liability for any compensation to any Intermediary (other than the Placement Agent) engaged by the Company and the fees and expenses of defending against said liability or alleged liability. 

3.17 Private Placement. Assuming the accuracy of the Purchasers’ representations and warranties set forth in Article II and the
responses to the questions on Schedule A hereof, and compliance by the Placement Agent with its obligations, no registration under the Securities Act is required for the offer and sale of the Securities to be delivered at Closing by the
Company to the Purchasers as contemplated hereby. 
 3.18 Exchange Act Registration. The Company’s Common Stock is registered
pursuant to Section 12(g) of the Exchange Act, and the Company has taken no action designed to, or which to its knowledge is likely to have the effect of, terminating the registration of the Common Stock under the Exchange Act nor has the
Company received any notification that the Commission is contemplating terminating such registration. 

  
 17 








 3.19 Reasonably Equivalent Value. The board of directors of the Company has determined
that the terms of the Securities offered hereunder represent the reasonably equivalent value with respect to the sale of the Securities. The Transaction Documents and the transactions contemplated thereby were the result of arms’ length
negotiations among the parties. 
 3.20 Representations Complete. None of the representations or warranties made by the Company in
this Agreement (except as modified by the Offering Materials, the Disclosure Schedules, or the SEC Reports) and none of the statements made by the Company in the Offering Materials contains any untrue statement of a material fact, or omits to state
any material fact necessary in order to make the statements contained herein or therein, in the light of the circumstances under which made, not misleading. No event or circumstance (other than the transactions contemplated by this Agreement) has
occurred or information exists with respect to the Company or its business, properties, prospects, operations or financial condition, which, under applicable federal law, rule or regulation, requires public disclosure or announcement by the Company
but which has not been so publicly announced or disclosed. 
 3.21 Tax Status. Except for matters that would not, individually or in
the aggregate, reasonably be likely to have a Material Adverse Effect, the Company has filed all necessary federal, state and foreign income and franchise tax returns and has paid or accrued all taxes shown as due thereon, and the Company has no
knowledge of a material tax deficiency which has been asserted or threatened against the Company. 
 3.22 Foreign Corrupt Practices.
Neither the Company, nor to the knowledge of the Company, any agent or other person acting on behalf of the Company, has (i) directly or indirectly, used any funds for unlawful contributions, gifts, entertainment or other unlawful expenses
related to foreign or domestic political activity, (ii) made any unlawful payment to foreign or domestic government officials or employees or to any foreign or domestic political parties or campaigns from corporate funds, (iii) failed to
disclose fully any contribution made by the Company (or made by any person acting on its behalf of which the Company is aware) which is in violation of law or (iv) violated in any material respect any provision of the Foreign Corrupt Practices
Act of 1977, as amended. 
 3.23 Disclosure. Except as set forth on Schedule 3.23, the Company confirms that it has not provided, and
to the Company’s knowledge, none of its officers or directors nor any other Person acting on its or their behalf has provided, and it has not authorized the Placement Agent to provide, any Purchaser (other than Timothy McInerney or any of his
Affiliates) or its respective agents or counsel with any information that it believes constitutes material, non-public information except insofar as the existence, provisions and terms of the Transaction Documents and the proposed transactions
hereunder may constitute such information, all of which will be disclosed by the Company in the press release as contemplated by Section 4.2 hereof. The Company understands and confirms that the Purchasers will rely on the foregoing
representations in effecting transactions in securities of the Company. The Company acknowledges and agrees that no Purchaser makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those
specifically set forth in Article 2 hereto.

 3.24 Environmental Matters. To the Company’s knowledge, none of the Company or any of
its Subsidiaries (i) is in violation of any statute, rule, regulation, decision or order of any governmental agency or body or any court, domestic or foreign, relating to the use, disposal or release of hazardous or toxic substances or relating
to the protection or restoration of the environment or human exposure to hazardous or toxic substances (collectively, “Environmental Laws”), (ii) owns or operates any real property contaminated with any substance that is in
violation of any Environmental Laws, (iii) is liable for any off-site disposal or contamination pursuant to any Environmental Laws, or (iv) is subject to any claim relating to any Environmental Laws; which violation, contamination,
liability or claim has had or would be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect; and there is no pending investigation or, to the Company’s knowledge, investigation threatened in writing that might
lead to such a claim. 
 3.25 Employment Matters. (i) no material labor dispute exists or, to the Company’s knowledge, is
imminent with respect to any of the employees of the Company which would have or would reasonably be expected to result in a Material Adverse Effect; (ii) none of the Company’s or any Subsidiary’s employees is a member of a labor
union that relates to such employee’s relationship with the Company, and neither the Company nor any of its Subsidiaries is a party to a collective bargaining agreement, (iii) no executive officer of the Company (as defined in Rule 501(f)
of the Securities Act) has notified the Company or any of its Subsidiaries in writing that such officer intends to leave the Company or any such Subsidiary or otherwise terminate such officer’s employment with the Company or any such
Subsidiary; and (iv) to the Company’s knowledge, no executive officer or key employee, is, or is now expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information
agreement or non-competition agreement, or any other contract or agreement or any restrictive covenant in favor of any third party, and to the Company’s knowledge, the continued employment of each such executive officer or key employee does not
subject the Company or any Subsidiary to any liability with respect to any of the foregoing matters, except, in each case, matters that, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect. The
Company is in compliance with all U.S. federal, state, local and foreign laws and regulations relating to employment and employment practices, terms and conditions of employment and wages and hours, except where the failure to be in compliance would
not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect. 
 3.26 Title to Assets. The
Company and each of its Subsidiaries has good and marketable title to all tangible personal property owned by it that is material to its business, in each case free and clear of all Liens except such as do not materially affect the value of such
property and do not interfere with the use made and proposed to be made of such property by the Company. Any real property and facilities held under lease by the Company and any of its Subsidiaries are, to the Company’s knowledge, held by it
under valid, subsisting and enforceable leases with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and its Subsidiaries. 

3.27 Regulation M Compliance. The Company has not, and to the Company’s knowledge no one acting on its behalf has, (i) taken,
directly or indirectly, any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company 

  
 19 








 
to facilitate the sale or resale of any of the Securities, (ii) sold, bid for, purchased, or, paid any compensation for soliciting purchases of, any of the Securities in violation of
Regulation M under the Exchange Act, or (iii) paid or agreed to pay to any Person any compensation for soliciting another to purchase any other securities of the Company, other than, in the case of clauses (ii) and (iii), it is
acknowledged by the Purchasers that the Company will pay compensation to the Placement Agent in connection with the placement of the Securities. 

3.28 Acknowledgment Regarding Purchasers’ Purchase of Securities. The Company acknowledges and agrees that each of the Purchasers
is acting solely in the capacity of an arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby. The Company further acknowledges that no Purchaser (other than Timothy McInerney,
Chairman of the Board of the Company and a principal of the Placement Agent) is acting as a financial advisor or fiduciary of the Company (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated
thereby and any advice given by any Purchaser or any of their respective representatives or agents (other than Mr. McInerney and the Placement Agent) in connection with the Transaction Documents and the transactions contemplated thereby is
merely incidental to the Purchasers’ purchase of the Securities. The Company further represents to each Purchaser that the Company’s decision to enter into this Agreement and the other Transaction Documents has been based solely on the
independent evaluation of the transactions contemplated hereby by the Company and its representatives. 
 3.29 Insurance. The Company
and each of its Subsidiaries is insured by insurers of recognized financial responsibility against such losses and risks and in such amounts as the Company believes to be prudent and customary in the businesses and locations in which the Company and
the Subsidiaries are engaged. None of the Company or any of its Subsidiaries has received any written notice of cancellation of any such insurance, nor, to the Company’s knowledge, will it or any Subsidiary be unable to renew its existing
insurance coverage as and when such coverage expires or to obtain similar coverage from similar insurers as may be necessary to continue its business without a material increase in cost. 

3.30 Regulatory Permits. The Company and each of its Subsidiaries possesses all certificates, authorizations and permits issued by the
appropriate federal, state, local or foreign regulatory authorities necessary to conduct its business as currently conducted, except as set forth in the SEC Reports, or where the failure to possess such permits, individually or in the aggregate, has
not and would not reasonably be expected to result in a Material Adverse Effect (“Material Permits”), and neither the Company nor any of its Subsidiaries has received any notice of Proceedings relating to the revocation or
modification of any such Material Permits. 
 3.31 Government Licenses. Except as set forth in the SEC Reports, (i) the Company
and its Subsidiaries possess such permits, certificates, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies
or bodies necessary to conduct the business of the Company as described in the SEC Reports, including without limitation, all such approvals, certificates, authorizations and permits required by the United States Food and Drug Administration (the
“FDA”) and/or other federal, state, local or foreign agencies or bodies engaged in the regulation of clinical trials, pharmaceuticals, or biohazardous substances or 

  
 20 








 
materials, except where the failure so to possess would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect; (ii) the Company and each of
its Subsidiaries is in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect;
(iii) all of the Governmental Licenses are valid and in full force and effect, except when the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not, individually or in
the aggregate, have or reasonably be expected to have a Material Adverse Effect; and (iv) neither the Company nor any of its Subsidiaries has received any written notice of proceedings relating to the revocation or modification of any such
Governmental Licenses which, individually or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would have or reasonably be expected to have a Material Adverse Effect. Except as set forth in the SEC Reports, where
required by applicable laws and regulations of the FDA or any foreign regulatory authority, the Company and each of its Subsidiaries has submitted to the FDA or any foreign regulatory authority an Investigational New Drug Application, or similar
application, or amendment or supplement thereto for a clinical trial it has conducted or sponsored or is conducting or sponsoring, except where such failure would not, individually or in the aggregate, have or reasonably be expected to have a
Material Adverse Effect; all such submissions were, to the Company’s knowledge, in material compliance with applicable laws and rules and regulations when submitted and no material deficiencies have been asserted by the FDA or such foreign
regulatory authority with respect to any such submissions, except any deficiencies which could not, individually or in the aggregate, have or reasonably be expected to have a Material Adverse Effect. 

3.32 No “Bad Actor” Disqualification. The Company has exercised reasonable care to determine whether any Issuer Covered
Person (as defined below) is subject to any of the “bad actor” disqualifications described in Rule 506(d)(1)(i) to (viii) under the Act (“Disqualification Events”). To the Company’s knowledge, no Issuer Covered
Person is subject to a Disqualification Event, except for a Disqualification Event covered by Rule 506(d)(2) or (d)(3) under the Act. The Company has complied, to the extent applicable, with any disclosure obligations under Rule 506(e) under the
Act. “Issuer Covered Persons” are certain of those persons specified in Rule 506(d)(1) under the Act, including the Company; any predecessor or affiliated issuer of the Company; any director, executive officer or other officer
participating in the sale of the Notes being issued hereunder; any beneficial owner of 20% or more of the Company’s outstanding voting equity securities, calculated on the basis of voting power; any promoter (as defined in Rule 405 under the

least two trading days prior to such filing. 
 (b) subject to Section 7.7 hereof, use its reasonable best efforts to keep such

of the Registrable Securities included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and 

(v) of the happening of any event that requires the making of any changes in a Registration Statement or the prospectus so that, as of such
date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of the prospectus, in the light of the circumstances under which they
were made) not misleading; 
 (d) make every reasonable effort to avoid the issuance of, or if issued, obtain the withdrawal of any order
suspending the effectiveness of any Registration Statement at the earliest possible time or any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for sale in any jurisdiction, as soon as
reasonably practicable; 
 (e) at each Holder’s written request, furnish to such Holder, without charge, at least one copy of such

conducting an investigation for the purpose of reducing or eliminating such Holder’s exposure to liability under the Securities Act, including the reasonable production of information at the Company’s headquarters; 

(g) prior to any public offering of Registrable Securities pursuant to any Registration Statement, register or qualify or obtain an exemption
for offer and sale under the securities or blue sky laws of such jurisdictions as any such Holders reasonably request in 

  
 28 








 
writing and do any and all other reasonable acts or things reasonably necessary or advisable to enable the offer and sale in such jurisdictions of the Registrable Securities covered by such

service of process in any such jurisdiction; (iii) subject itself to taxation in any such jurisdiction; (iv) provide any undertakings that cause material expense or burden to the Company; or (v) make any change to its organizational

denominations and registered in such names as Holders, the managing underwriter or agent may request at least two (2) business days prior to sales of Registrable Securities pursuant to such Registration Statement, subject to the submission by
Holder to the Company’s transfer agent of the original certificate(s) representing the Registrable Securities to be sold and a separate Holder’s Certificate of Subsequent Sale, in a form reasonably satisfactory to the Company, duly
executed by the Holder and all other documentation reasonably required by the Company and the Company’s transfer agent (all of which must be provided to the Company a reasonable period of time prior to the date such Holder intends to sell such
Registrable Securities); 
 (i) subject to Section 7.7 hereof, upon the occurrence of any event contemplated by Section 7.4(b)(v)
above, the Company shall promptly prepare a post-effective amendment to the Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter promptly delivered to purchasers of the
Registrable Securities included therein, the prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were
made, not misleading; and 
 (j) use its best efforts to comply with all applicable rules and regulations of the Commission, and use its
reasonable best efforts to make generally available to the Holders (which may be satisfied upon filing via EDGAR) not later than 45 days (or 90 days if the fiscal quarter is the fourth fiscal quarter) after the end of its fiscal quarter in which the
first anniversary date of the effective date of any Registration Statement occurs, an earnings statement satisfying the provisions of Section 11(a) of the Securities Act. 

Notwithstanding the foregoing, it shall be a condition precedent to the obligations of the Company to take any action pursuant to paragraphs
(a) through (j) of this Section 7.4, that the Holder shall furnish to the Company such information regarding itself, the Registrable Securities to be sold by the Holder, and the intended method of disposition of such Registrable
Securities as shall be required to effect the registration of the Registrable Securities, all of which information shall be furnished to the Company in writing specifically for use in the Registration Statement. 

  
 29 








 7.5 The Holders shall have no right to take any action to restrain, enjoin or otherwise delay any
registration pursuant to Section 7.2 hereof as a result of any controversy that may arise with respect to the interpretation or implementation of this Agreement. 

7.6 (a) To the extent permitted by law, the Company shall indemnify each Holder and Affiliate of each Holder, and their respective officers,
directors, agents, investment advisors, partners, members and employees, with respect to which any registration, qualification or compliance has been effected pursuant to this Agreement, against all claims, losses, damages and liabilities (or action
in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 7.6(c) below), arising out of or based on any untrue statement (or alleged untrue statement) of a material
fact contained in any Registration Statement or any amendment or supplement thereof, or any Prospectus or any amendment or supplement thereof (including any preliminary prospectus), or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, and will reimburse each Holder and Affiliate of each Holder, and their respective
officers, directors, agents, investment advisors, partners, members and employees, for reasonable legal and other expenses reasonably incurred by such person in connection with investigating or defending any such claim, loss, damage, liability or
action as incurred; provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability or action arises out of, relates to or is based upon (i) an untrue statement or omission made in
reliance upon and in conformity with written information furnished to the Company by or on behalf of such Holder or person controlling such Holder and stated to be specifically for use in preparation of such Registration Statement, Prospectus or any
supplement or amendment thereto, or (ii) the failure of the Holder to comply with the covenants and agreements contained in this Agreement respecting sales of Registrable Securities. 

(b) Each Holder will severally and not jointly, if Registrable Securities held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify the Company, its Subsidiaries, and each of their respective directors, officers and agents and each Affiliate of the foregoing, against all claims, losses, damages, liabilities
and expenses (or actions in respect thereof), including any of the foregoing incurred in settlement of any litigation, commenced or threatened (subject to Section 7.6(c) below), arising out of or based on any untrue statement of a material fact
contained in any Registration Statement or any amendment or supplement thereof, or any Prospectus or any amendment or supplement thereof (including any preliminary prospectus), or based on any omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading, in light of the circumstances in which they were made, in each case to the extent, but only to the extent, that such untrue statement or omission thereof is made in reliance
upon and in conformity with written information furnished to the Company by or on behalf of the Holder specifically for use in preparation of such Registration Statement, Prospectus or any amendment or supplement thereto or is due to the failure of
the Holder to comply with the covenants and agreements contained in the Agreement with respect to the sale of Registrable Securities, and the Holder will reimburse the Company, its directors and officers, and each person controlling the Company for
reasonable legal and any other expenses reasonably incurred in connection with investigating, defending, settling, compromising or paying any such claim, loss, damage, liability, expense or action as incurred. Notwithstanding the foregoing, in no
event shall a Holder be liable for any such claims, losses, damages or liabilities in an amount greater than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such Holder’s
indemnification obligation, except in the event of fraud or intentional misrepresentation. 
  

  
 30 








 (c) Each party entitled to indemnification under this Section 7.6 (the “Indemnified
Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, provided
that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Agreement, unless such failure is materially prejudicial to the Indemnifying Party in defending such
claim or litigation. Subject to provisions hereinafter stated, in case any such action is brought against any Indemnified Party and such Indemnified Party seeks or intends to seek indemnity from an Indemnifying Party, the Indemnifying Party will be
entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof with counsel reasonably satisfactory to such Indemnified Party; provided, however, if the
defendants in any such action include both the Indemnified Party and the Indemnifying Party, and the Indemnifying Party and the Indemnified Party, based upon the advice of such Indemnified Party’s counsel, shall have reasonably concluded that
there may be a conflict of interest between the positions of the Indemnifying Party and the Indemnified Party in conducting the defense of any such action or that there may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the Indemnifying Party, the Indemnified Party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on
behalf of such Indemnified Party or parties. Upon receipt of notice from the Indemnifying Party to such Indemnified Party of its election so to assume the defense of such action and approval by the Indemnified Party of counsel, the Indemnifying
Party will not be liable to such Indemnified Party under this Section 7.6 for any legal or other expenses subsequently incurred by such Indemnified Party in connection with the defense thereof unless (i) the Indemnified Party shall have
employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the Indemnifying Party shall not be liable for the expenses of more than one
separate counsel, which counsel will be disclosed by the Indemnified Parties to the Indemnifying Party), or (ii) the Indemnifying Party shall not have employed counsel reasonably satisfactory to the Indemnified Party to represent the
Indemnified Party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the Indemnifying Party. In no event shall any Indemnifying Party be
liable in respect of any amounts paid in settlement of any action unless the Indemnifying Party shall have approved the terms of such settlement; provided that such approval shall not be unreasonably withheld. 

(d) If the indemnification provided for in this Section 7.6 is held by a court of competent jurisdiction to be unavailable to an
Indemnified Party with respect to any loss, liability, claim, damage or expense referred to therein (other than due to the exemptions to indemnity set forth in Section 7.6(a) above), then the Indemnifying Party, in lieu of indemnifying such
Indemnified Party thereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability, claim, damage or expense in such proportion 

  
 31 








 
as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions or inaccuracies
in the representations and warranties in this Agreement which resulted in such loss, liability, claim, damage or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified
Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact or the inaccurate representation and/or warranty relates to information
supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, in no event shall
a Holder be liable for any such claims, losses, damages or liabilities pursuant to this paragraph 7.6(d) in an amount greater than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise
to such Holder’s indemnification obligation, except in the event of fraud or intentional misrepresentation. 
 7.7(a) Notwithstanding
any other provision of this Agreement, each Holder agrees that, upon receipt of any notice from the Company of the happening of any event requiring the preparation of a supplement or amendment to a prospectus relating to Registrable Securities or
the filing of an appropriate report with the SEC pursuant to the Exchange Act, so that, as thereafter delivered to the Holders, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact required to
be stated therein or necessary to make the statements therein not misleading, each Holder will forthwith discontinue disposition of Registrable Securities pursuant to the Registration Statement contemplated by Section 7.2 until its receipt of
copies of the supplemented or amended prospectus from the Company or confirmation of the filing of such report with the SEC by the Company, any such prospectus to be forwarded promptly to the Purchaser by the Company, and, if so directed by the
Company, each Holder shall deliver to the Company all copies, other than permanent file copies then in such Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. 

(b) Notwithstanding any other provision of this Agreement, each Holder shall suspend, upon request of the Company, any disposition of
Registrable Securities pursuant to the Registration Statement and prospectus contemplated by Section 7.2 during any periods not to exceed 90 days in the aggregate within any one 12 month period when the Company reasonably determines in good
faith that offers and sales pursuant thereto should not be made by reason of the presence of material undisclosed circumstances or developments with respect to which the disclosure that would be required in such a prospectus is premature, would have
an adverse effect on the Company or is otherwise inadvisable. 
 (c) As a condition to the inclusion of its Registrable Securities, each
Holder shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing or as shall be required in connection with any registration, qualification or
compliance referred to in this Article VII. 

  
 32 








 (d) Each Holder hereby covenants with the Company not to make any sale of any Registrable
Securities without effectively causing the prospectus delivery requirements under the Securities Act to be satisfied. 
 (e) Each Holder
acknowledges and agrees that Registrable Securities sold pursuant to any Registration Statement described in this Section are not transferable on the books of the Company unless the stock certificate submitted to the transfer agent evidencing such
Registrable Securities is accompanied by a certificate reasonably satisfactory to the Company to the effect that (i) such Registrable Securities have been sold in accordance with such Registration Statement and (ii) the requirement of
delivering a current prospectus has been satisfied. 
 (f) Each Holder agrees not to take any action with respect to any distribution deemed
to be made pursuant to such Registration Statement which would constitute a violation of Regulation M under the Exchange Act or any other applicable rule, regulation or law. 

(g) At the end of the period during which the Company is obligated to keep the Registration Statement current and effective as described
above, the Holders of Registrable Securities included in the Registration Statement shall discontinue sales of shares pursuant to such Registration Statement upon receipt of notice from the Company of its intention to remove from registration the
shares covered by such Registration Statement which remain unsold, and such Holders shall notify the Company of the number of shares registered which remain unsold immediately upon receipt of such notice from the Company. 

7.8 With a view to making available to the Holders the benefits of certain rules and regulations of the Commission which at any time permit
the sale of the Registrable Securities to the public without registration, the Company shall use its reasonable best efforts to: 
 (a) make
and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, at all times; 
 (b)
file with the Commission in a timely manner all reports and other documents required of the Company under the Exchange Act; and 
 (c) so
long as a Holder owns any unregistered Registrable Securities, furnish to such Holder, upon any reasonable written request, a written statement by the Company as to its compliance with Rule 144 under the Securities Act, and of the Exchange Act, a
copy of the most recent annual or quarterly report of the Company, and such other reports and documents of the Company as such Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any
such securities without registration. 
 7.9 Subject to Section 8.3, the rights to cause the Company to register Registrable Securities
granted to the Holders by the Company under Section 7.2 may be assigned in full by a Holder in connection with a transfer by such Holder of its Registrable Securities, but only if: (i) such transfer may otherwise be effected in accordance
with applicable securities laws; (ii) such Holder gives prior written notice of the proposed transfer to the Company including the name and address of such transferee and a copy of the transfer documents and agreements;


  
 33 








 
(iii) such transferee agrees in writing with the Company to be bound by and to comply with the terms and provisions of this Agreement; (iv) the transferee is an “accredited
investor” as that term is defined in Rule 501 of Regulation D; and (v) such transfer is otherwise in compliance with this Agreement and the applicable Warrants. Except as specifically permitted by this Section 7.9, the rights of a
Holder with respect to Registrable Securities as set forth herein shall not be transferable to any other person, the Company may impose stop transfer orders with respect to any such transfer or attempted transfer, and any such transfer or attempted
transfer shall be null and void. 
 7.10 The Company shall use reasonable best efforts to cause all Registrable Securities covered by a
Registration Statement to be listed on each securities exchange, interdealer quotation system or other market on which similar securities issued by the Company are then listed. 

7.11 With the written consent of the Company and the Holders holding at least a majority of the Registrable Securities that are then
outstanding, any provision of this Article VII may be waived (either generally or in a particular instance, either retroactively or prospectively and either for a specified period of time or indefinitely) or amended and shall be effective against
all Holders. Upon the effectuation of each such waiver or amendment, the Company shall promptly give written notice thereof to the Holders, if any, who have not previously received notice thereof or consented thereto in writing. 

7.12 The Company acknowledges and agrees that irreparable damage would occur in the event that any of the provisions of this Article VII were
not performed in accordance with its specific terms or were otherwise breached and that such damage would not be compensable in money damages and that it would be extremely difficult or impracticable to measure the resultant damages. Accordingly,
except as otherwise specifically set forth herein, any Purchaser shall be entitled to an injunction or injunctions with respect to the provisions of this Article VII and to enforce specifically the terms and provisions hereof, in addition to any
other remedy to which it may be entitled at law or in equity, and the Company expressly waives any defense that a remedy in damages would be adequate and expressly waives any requirement in an action for specific performance for the posting of a
bond by the Purchaser bringing such action. 
 7.13 If at any time during the Registration Period for a particular Registration Statement
there is not an effective Registration Statement covering all of the Registrable Securities and the Company shall determine to prepare and file with the Commission a registration statement relating to an offering for its own account or the account
of others under the Securities Act of any of its equity securities, other than on Form S-4 or Form S-8 (each as promulgated under the Securities Act) or their then equivalents relating to equity securities to be issued solely in connection with any
acquisition of any entity or business or equity securities issuable in connection with stock option or other employee benefit plans, then the Company shall send to each Holder written notice of such determination and, if within ten
(10) business days after receipt of such notice, any such Holder shall so request in writing, the Company shall include in such registration statement all or any part of such Registrable Securities such holder requests to be registered, subject
to customary underwriter cutbacks applicable to all holders of registration rights.

to such modification, amendment or waiver. Any such modification, amendment or waiver shall be limited to its express terms. It is agreed that a waiver by either party of a breach of any provision of this Agreement shall not operate, or be

 8.3 A Purchaser may not assign or transfer any of its rights or
obligations under any of the Transaction Documents without the prior written consent of the Company; provided that, notwithstanding the foregoing, a Purchaser may, without the prior written consent of the Company (a) assign its rights

parties as to the subject matter hereof and merges and supersedes all prior discussions, agreements and understandings of any and every nature among them. 

8.4 Upon the execution and delivery of this Agreement by the Purchaser, this Agreement shall become a binding obligation of the Purchaser with
respect to the purchase of the Securities as herein provided; subject, however, to the right hereby reserved to the Company to revoke a Purchaser’s subscription in accordance with Section 5.4. 

  
 35 








 8.5 NOTWITHSTANDING THE PLACE WHERE THIS AGREEMENT MAY BE EXECUTED BY ANY OF THE PARTIES HERETO,
THE PARTIES EXPRESSLY AGREE THAT ALL THE TERMS AND PROVISIONS HEREOF SHALL BE CONSTRUED IN ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW. IN THE EVENT THAT A JUDICIAL PROCEEDING IS
NECESSARY, THE EXCLUSIVE FORUMS FOR RESOLVING DISPUTES ARISING OUT OF OR RELATING TO THIS AGREEMENT ARE EITHER THE SUPREME COURT OF THE STATE OF NEW YORK IN AND FOR THE COUNTY OF NEW YORK OR THE FEDERAL COURTS FOR SUCH STATE AND COUNTY, AND ALL
RELATED APPELLATE COURTS, THE PARTIES HEREBY IRREVOCABLY CONSENT TO THE JURISDICTION OF SUCH COURTS AND AGREE TO SAID VENUE. EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL
BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. 
 8.6 The holding of
any provision of this Agreement to be invalid or unenforceable by a court of competent jurisdiction shall not affect any other provision of this Agreement, which shall remain in full force and effect. If any provision of this Agreement shall be
declared by a court of competent jurisdiction to be invalid, illegal or incapable of being enforced in whole or in part, such provision shall be interpreted so as to remain enforceable to the maximum extent permissible consistent with applicable law
and the remaining conditions and provisions or portions thereof shall nevertheless remain in full force and effect and enforceable to the extent they are valid, legal and enforceable, and no provisions shall be deemed dependent upon any other
covenant or provision unless so expressed herein. 
 8.7 The parties agree to execute and deliver all such further documents, agreements and
instruments and take such other and further action as may be necessary or appropriate to carry out the purposes and intent of this Agreement. 

8.8 This Agreement may be executed in two or more counterparts each of which shall be deemed an original, but all of which shall together
constitute one and the same instrument. 
 8.9 (a) The Purchasers severally agree not to issue any public statement with respect to the
Purchasers’ investment or proposed investment in the Company or the terms of any agreement or covenant between them and the Company without the Company’s prior written consent, except such disclosures as may be required under applicable
law or under any applicable order, rule or regulation. 
 (b) The Company agrees not to disclose the names, addresses or any other
information about the Purchasers, except as required by law and to satisfy its obligations under Article VII. 
 8.10 Each Purchaser
represents and warrants that it has not engaged, consented to nor authorized any broker, finder or intermediary to act on its behalf, directly or indirectly, as a broker, finder or intermediary in connection with the transactions contemplated by
this Agreement, which, for the avoidance of doubt, does not include the Placement Agent. Each Purchaser hereby severally agrees to indemnify and hold harmless the Company from and against all fees, commissions or other payments owing to any such
person or firm acting on behalf of such Purchaser hereunder.
