REPRESENTATIONS AND WARRANTIES 

3.1 Representations and Warranties of the Company. The Company hereby represents and warrants to the Purchasers as follows: 

(a) Organization and Qualification. The Company is a corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware and has the requisite legal authority to own and use its properties and assets and to carry on its business as currently conducted. The Company is duly qualified to do business and is in good standing as a foreign
corporation or other entity in each jurisdiction in which the nature of the business conducted or property owned by the Company makes such qualification necessary, except where the failure to be so qualified or in good standing, as the case may be,
would not, individually or in the aggregate, have, or reasonably be expected to result in, a Material Adverse Effect (defined below). For purposes of this Agreement, “Material Adverse Effect” means (i) a material adverse
effect on the results of operations, assets, business or financial condition of the Company and its Subsidiaries, taken as a whole on a consolidated basis, or (ii) material and adverse impairment of the Company’s ability to perform its
obligations under this Agreement, provided that none of the following alone shall be deemed, in and of itself, to constitute a Material Adverse Effect: (A) a change in the market price or trading volume of the shares of Common Stock of the
Company or (B) changes in general economic conditions or changes affecting the industry in which the Company operates generally (as opposed to Company-specific changes) so long as such changes do not have a disproportionate effect on the
Company and its Subsidiaries, taken as a whole. 
 (b) Authorization; Enforcement. The Company has the requisite corporate
authority to enter into this Agreement and to carry out its obligations hereunder. The execution and delivery of this Agreement and the certificates representing the Notes and Warrants have been duly authorized by all necessary corporate action
on the part of the Company. This Agreement has been duly executed and delivered by the Company and constitutes, and the certificates representing the Notes and Warrants, when executed and delivered in accordance with the terms hereof, will
constitute, a valid and binding obligation of the Company enforceable against the Company in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization or other laws of general application
relating to or affecting the enforcement of creditors’ rights generally; (ii) the effect of rules of law governing the availability of specific performance and other equitable remedies; and (iii) insofar as indemnification and
contribution provisions may be limited by applicable law. 

  
 5 

 (c) Required Approvals; No Conflicts. Subject to the Required Approvals, the
execution and delivery by the Company of this Agreement and the certificates representing the Notes and Warrants, and the performance by the Company of its obligations hereunder and thereunder, do not and will not (i) conflict with or violate
any provision of the Company’s certificate of incorporation, bylaws or other organizational or charter documents, (ii) conflict with, or constitute a default under (or an event that, with notice or lapse of time or both, would become a
default under), or give to others any rights of termination, amendment, acceleration or cancellation under (with or without notice, lapse of time or both), any agreement, credit facility, debt or other instrument evidencing a debt of the Company or
other understanding to which the Company is a party, or by which any of its properties or assets is bound, except to the extent that such conflict or default or termination, amendment, acceleration or cancellation right would not reasonably be
expected to have a Material Adverse Effect, or (iii) result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company is subject, or by
which any of its properties or assets is bound, except to the extent that such violation would not reasonably be expected to have a Material Adverse Effect. The Company is not required to obtain any consent, waiver, authorization or order of, give
any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other Person in connection with the execution, delivery and performance by the Company of the Transaction Agreements,
other than: (i) the filings required pursuant to Section 4.1 of this Agreement and (ii) the Required Approvals. 
 (d)
Due Issuance. The Notes and the Warrants are duly authorized and, when issued and paid for in accordance with the applicable Transaction Agreements, the Notes and the Warrants will constitute legal, valid and binding obligations of the
Company. The Warrant Shares, when issued in accordance with the terms of the Warrants, will be validly issued, fully paid and non-assessable, free and clear of all Liens imposed by the Company other than restrictions on transfer provided for in the
Transaction Agreements. 
 (e) Property. The Company does not own any real property. The Company and its subsidiaries have good and
marketable title to all properties and assets described in the SEC Reports as owned by it, in each case free and clear of all Liens, except such as (i) are described in the SEC Reports or (ii) 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 and its subsidiaries. Any real property and buildings held under lease by the Company and its subsidiaries are held by them under valid,
subsisting and enforceable leases with such exceptions as do not interfere with the use made and proposed to be made of such property and buildings by the Company and its subsidiaries. 

(f) Capitalization. The capitalization of the Company is as set forth in the Company’s SEC Reports and as set forth in this
paragraph. The Company has not issued any capital stock since its most recently filed report under the Exchange Act, other than (i) pursuant to the exercise of stock options or vesting of restricted stock units granted under the Company’s
equity compensation plans, (ii) the issuance of shares of Common Stock or restricted stock units to employees, directors or other eligible persons pursuant to the Company’s equity compensation plans, (iii) pursuant to the conversion
and/or exercise of Common Stock Equivalents outstanding as of the date hereof, and pursuant to the terms and conditions for the payment of dividends pursuant to the Certificate of Designations, Preferences and Rights and Number of Shares of Series D
Convertible Preferred Stock. Except as disclosed in the SEC Reports or as a result of the purchase and sale of the Securities, there are no outstanding options, warrants, scrip rights to subscribe to, calls or commitments of any character whatsoever
relating to, or securities, rights or obligations convertible into or exercisable or exchangeable for, or giving any Person any right to subscribe for or acquire any shares of Common Stock or Common Stock Equivalents, or binding written contracts by
which the Company or any Subsidiary is bound to issue additional shares of Common Stock or Common Stock Equivalents other than (x) such equity and/or debt securities of the 

  
 6 

 
Company as may be issued in a transaction with the holder of a promissory note in the aggregate principal amount of $950,000 and (y) a maximum of 900,000 common stock purchase warrants
issuable to a consultant pursuant to a services agreement. The issuance and sale of the Securities will not obligate the Company to issue shares of Common Stock or other securities to any Person (other than the Purchaser) and will not result in a
right of any holder of Company securities to adjust the exercise, conversion, exchange or reset price under any of such securities. All of the outstanding shares of capital stock of the Company are duly authorized, validly issued, fully paid and
non-assessable, have been issued in compliance with all federal and state securities laws, and none of such outstanding shares was issued in violation of any preemptive rights or similar rights to subscribe for or purchase securities. 

(g) SEC Reports; Financial Statements. The Company has filed all SEC Reports required to be filed by it under the Exchange Act for the
two years preceding the date hereof (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. As of their
respective dates, the SEC Reports filed for the two years preceding the date hereof have complied in all material respects with the requirements of the Exchange Act and the rules and regulations promulgated thereunder, and none of such 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 the light of the circumstances under which they were made, not
misleading. The financial statements of the Company, together with the related schedules and the notes thereto, included or incorporated by reference in the SEC Reports comply in all material respects with applicable accounting requirements and the
applicable requirements of the Securities Act and Exchange Act as in effect at the time of filing. Such financial statements have been prepared in accordance with 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 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. 

(h) Material Liabilities and Indebtedness. Since the date of the latest financial statements included in the SEC Reports, except as

expected to result in, individually or in the aggregate, a Material Adverse Effect.

business, except where failure to do so could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The term “Intellectual Property” as used herein means all patents, patent applications,

that could, in the aggregate, reasonably be expected to have a Material Adverse Effect. Except as may be contemplated by the immediately preceding sentence, the Company has no knowledge of any proposed liability for any tax to be imposed upon the

rules and regulations of the Commission thereunder; and (iii) neither the Company nor any other Person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with the terms and
conditions of any exemption thereunder. Further, the Company may place a stop transfer order on its transfer books against the Warrant Shares if such is required in the reasonable opinion of counsel to the Company pursuant to applicable securities
laws. Subject to the restrictions in the Warrant, such stop order will be removed, and further transfer of such shares of Common Stock will be permitted, upon an effective registration of the Warrant Shares or the receipt by the Company of an
opinion of counsel satisfactory to the Company that such further transfer may be effected pursuant to an applicable exemption from registration. 

(e) Own Account. Such Purchaser understands that the Securities have not been registered under the Securities Act or any applicable
state securities law and is acquiring the Securities as principal for its own account and not with a view to or for distributing or reselling such Securities or any part thereof in violation of the Securities Act or any applicable state securities
law, has no present intention of distributing any of such Securities in violation of the Securities Act or any applicable state securities law and has no direct or indirect arrangement or understandings with any other persons to distribute or
regarding the distribution of such Securities in violation of the Securities Act or any 

  
 10 

 
applicable state securities law (this representation and warranty not limiting such Purchaser’s right to sell the Securities pursuant to the Registration Statement or otherwise in compliance
with applicable federal and state securities laws). Such Purchaser is acquiring the Securities hereunder in the ordinary course of its business. 

(f) Reliance on Representations. Such Purchaser understands that the Notes and Warrants are being offered and sold to it in reliance
on specific exemptions from the registration requirements of United States federal and state securities laws and that the Company is relying in part upon the truth and accuracy of, and such Purchaser’s compliance with, the representations,
warranties, agreements, acknowledgments and understandings of such Purchaser set forth herein and in the applicable schedules and exhibits in order to determine the availability of such exemptions and the eligibility of such Purchaser to acquire the
Notes and Warrants The Purchaser undertakes to immediately notify the Company of any change in any statement or other information relating to the Purchaser set forth in such applicable schedules and exhibits which takes place prior to the applicable
Closing time. No Person has made any written or oral representations to the Purchaser that (i) any Person will resell or repurchase the Notes or Warrants, (ii) that any Person will refund all or any part of the Purchase Price, or
(iii) as to the future price or value of the shares of Common Stock of the Company. 
 (g) Purchaser Status. On the date
such Purchaser was offered the Notes and Warrants and on the date hereof and on each date on which it exercises any Warrants, such Purchaser is and will be either an “accredited investor” as defined in Rule 501(a) promulgated
under Regulation D of the Securities Act or a “qualified institutional buyer” as defined in Rule 144A(a) under the Securities Act. Such Purchaser is not required to be registered as a broker-dealer under Section 15 of the
Exchange Act. The Purchaser has properly completed, executed and delivered to the Company the applicable “accredited investor” certificate set forth in the annexes hereto and the information contained therein is true and correct. If
Purchaser is a trust, it either (i) owns total assets in excess of $5,000,000, was not formed for the specific purpose of acquiring the Securities offered hereby and its investment decisions are directed by a person who has such knowledge and
experience in financial and business matters that it is capable of evaluating the merits and risk of the trust’s investments; (ii) is a revocable trust which may be amended or revoked at any time by the grantors thereof and all of the
grantors are accredited investors and such grantors have separately indicated the basis on which they are accredited investors; or (iii) is a bank as defined in Section 3(a)(2) of the Securities Act, a savings and loan association or other
institution as defined in Section 3(a)(5) of the Securities Act and is acting in a fiduciary capacity on behalf of a trust account. 

(h) Absence of Certain Events. Neither the Purchaser nor any director, executive officer, other member or officer of the Purchaser
participating in the transactions contemplated by this Agreement, any beneficial owner of 20% of more of the Purchaser’s outstanding voting equity securities, calculated on the basis of voting power, nor any promoter (as that term is defined in
Rule 405 under the Securities Act) connected with the Purchaser in any capacity at the time of sale (each a “Purchaser Covered Person”) is subject to any of the “Bad Actor” disqualifications described in Rule 506(d)(1)(i)
to (viii) under the Securities Act (a “Disqualification Event”), except for a Disqualification Event covered by Rule 506(d)(2) or (3) (provided that the foregoing exception shall not be available hereunder with respect to
Rule 506(d)(2)(iv) for any Disqualification Event of which the Company did not know as a result of the Purchaser’s failure to disclose such Disqualification Event to the Company as otherwise required by this Section 3.2). Such Purchaser
has exercised reasonable care to determine (i) the identity of each person that is a Purchaser Covered Person and (ii) whether any Purchaser Covered Person is subject to a Disqualification Event. 

(i) Experience of Purchaser. There are risks associated with the purchase of and investment in the Notes and Warrants and the
Purchaser, either alone or together with his, her or its 

  
 11 

 
representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of entering into this Agreement and
making his, her or its Purchase Price and the merits and risks of the prospective investment in the Notes and Warrants and such Purchaser has so evaluated such merits and risks. Such Purchaser understands that he, she or it must bear the
economic risk of an investment in the Notes and Warrants indefinitely and is able to bear such risk and to afford a complete loss of such investment. 

(j) Access to Information. Such Purchaser acknowledges that he, she or it has had the opportunity to review the SEC Reports and
has reviewed such SEC Reports as it has, in its discretion, chosen and has been afforded (i) the opportunity to ask such questions as he, she or it has deemed necessary of, and to receive answers from, representatives of the Company concerning
the terms and conditions of this Agreement and the merits and risks of the prospective investment in the Notes and Warrants, (ii) access to information about the Company and its Subsidiaries and their respective financial condition, results of
operations, business, properties, management and prospects sufficient to enable him, her or it to evaluate the terms and conditions of this Agreement and the merits and risks of the prospective investment in the Notes and Warrants and (iii) the
opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed decision. Such Purchaser and its advisors, if any, in acquiring the Notes and
Warrants, have relied solely on their independent investigation of the Company and have been afforded the opportunity to ask questions of the Company. Such Purchaser understands that its investment in the Notes and Warrants involves a high degree of
risk. Such Purchaser has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Notes and Warrants. Purchaser participated in the drafting and
negotiation of, has carefully read and is familiar with this Agreement. Purchaser acknowledges that he has received no representations or warranties from the Company, its affiliates, employees, agents or attorneys in making his decision to enter
into this Agreement, other than as set forth herein. 
 (k) Certain Information. The Purchaser acknowledges that the fact of this
transaction, and certain other material financial and business matters that have not been publically disclosed, constitute material non-public information of the Company. Any use of this information by you, or any other person to whom you have
communicated such information, for any purpose other than your consideration of an investment in the Company, may be a criminal offense and subject you to criminal and civil liability. 

(l) No Governmental Review. Each Purchaser understands that no United States federal or state agency, or any other government or
governmental agency has reviewed or passed on or made, or will pass on or make, any recommendation or endorsement of the Notes and Warrants or the fairness or suitability of the prospective investment in the Notes and Warrants 

(m) No Legal, Tax or Investment Advice. Each Purchaser understands that nothing in this Agreement or any other materials
presented by or on behalf of the Company to him, her or it in connection with this Agreement and the transactions contemplated herein, including the prospective investment in the Notes, constitutes legal, tax or investment advice. Each
Purchaser has consulted such legal, tax and investment advisors as he, she or it, in his, her or its sole discretion, has deemed necessary or appropriate in the circumstances. The Purchaser is not relying on the Company or its counsel in this
regard. 
 The Company acknowledges and agrees that the Purchaser does not make or has not made any representations or warranties with
respect to the transactions contemplated hereby other than those specifically set forth in this Section 3.2.

contemplated hereby and including the form of this Agreement as an exhibit thereto. The Company and the Purchasers shall consult with each other in issuing any press releases with respect to the transactions contemplated hereby, and neither the
Company nor the Purchasers shall issue any such press release without the prior consent of the Company, with respect to any press release of any of the Purchasers, or without the prior consent of the Purchasers holding a majority of the Notes, with

such public statement or communication.

 4.3 Transfer Restrictions. 

(a) The Securities may only be disposed of in compliance with state and federal securities laws. In connection with any transfer of
Securities other than pursuant to an effective registration statement or Rule 144, to the Company or to an Affiliate of a Purchaser, the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the
transferor and reasonably acceptable to the Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the
Securities Act. As a condition of transfer, any such transferee shall agree in writing to be bound by the terms of this Agreement. The Purchasers agree to the imprinting, so long as is required by this Section 4.3, of a legend on any of the
Securities substantially in the following form: 
 [NEITHER] THIS SECURITY [NOR THE SECURITIES INTO WHICH THIS SECURITY IS [EXERCISABLE]
[CONVERTIBLE]] HAS [NOT] BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF
THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE TRANSFEROR TO SUCH EFFECT, THE SUBSTANCE OF WHICH SHALL BE REASONABLY ACCEPTABLE TO THE COMPANY. 

4.4 Certain Transactions and Confidentiality. Each Purchaser covenants that neither it nor any Affiliate acting on its behalf or
pursuant to any understanding with it will execute any purchases or sales, including short sales, as defined in Rule 200 of Regulation SHO under the Exchange Act (“Short Sales”), of any of the Company’s securities during the
period commencing with the execution of this Agreement and ending at such time that the transactions contemplated by this Agreement are first publicly announced pursuant to Section 4.1. Each Purchaser covenants that until such time
as the transactions contemplated by this Agreement are publicly disclosed by the Company, such Purchaser will maintain the confidentiality of the existence and terms of this transaction. Notwithstanding the foregoing

  
 13 

 
and notwithstanding anything contained in this Agreement to the contrary, the Company expressly acknowledges and agrees that unless a Purchaser possesses material, non-public information with
respect to the Company, has entered into a confidentiality agreement with the Company, or otherwise is restricted in its trading activities with respect to the Company’s Securities, (i) no Purchaser makes any representation, warranty or
covenant hereby that it will not engage in effecting transactions in any securities of the Company after the time that the transactions contemplated by this Agreement are first publicly announced; (ii) no Purchaser shall be restricted or
prohibited from effecting any transactions in any securities of the Company in accordance with applicable securities laws from and after the time that the transactions contemplated by this Agreement are first publicly announced; and (iii) no
Purchaser shall have any duty of confidentiality to the Company or its Subsidiaries relating to this Agreement after the initial disclosure of the transactions contemplated by this Agreement.

and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the
Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide evidence of such actions promptly upon request of any Purchaser.

whatsoever on the obligations between the Company and the other Purchasers, or (b) by the Company (except for any breach by it or failure to perform or satisfy any closing condition applicable to it), by written notice to the other parties;

5.2 Confidentiality. Each Purchaser acknowledges that due to certain of the covenants contained herein or in the other Transaction
Agreements, from time to time the Purchasers may come into possession of confidential information of the Company, including material, non-public information relating to the Company. The Purchasers hereby agree that (i) they shall keep all such
information strictly confidential, applying, at a minimum, the same degree of care as it does to protect its own confidential information of a similar nature; (ii) shall only use such information in connection with the transactions contemplated
by this Agreement; and (iii) shall not disclose any of such information other than: (a) to the Purchaser’s employees, representatives, directors, attorneys, auditors, or Affiliates who are advised of the confidential nature of such

case of waiver by or on behalf of all of the Purchasers, such written instrument shall be signed by Purchasers representing a Majority in Interest; and provided, further that that any amendment that would (i) reduce the principal amount of any
Note, (ii) reduce the percentage in aggregate principal amount of Notes outstanding necessary to modify or amend the Notes; or (iii) modify this Section 5.4 shall, in each case, require the approval of each Purchaser to which such
amendment shall apply. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other
provision, condition or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right.

respect to the subject matter hereof and supersede all prior agreements and understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such agreements and exhibits. At or after each

governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning the interpretations,
enforcement and defense of the transactions contemplated by this Agreement (whether brought against a party hereto or its respective Affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in the state and
federal courts sitting in the City of New York, Borough of Manhattan. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan for the adjudication of
any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject
to the jurisdiction of any such court, that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably waives personal service of process and consents to process being served in any
such suit, action or proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service
shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law. If either party shall commence an action or
proceeding to enforce any provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable attorneys’ fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such action or proceeding.

all rights provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under this Agreement. The parties agree that monetary damages may not be adequate

counterparts (including by facsimile or e-mail transmission), all of which when taken together shall be considered one and the same agreement. In the event that any signature is delivered by facsimile transmission or e-mail attachment, such
signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or e-mail-attached signature page were an original thereof. 

5.13 Survival; Severability. All covenants and other agreements set forth in this Agreement shall survive the applicable
Closing for the respective periods set forth therein and if no such period is specified until the maturity date of the Notes. If any provision of this Agreement is held to be invalid or unenforceable in any respect, the validity and enforceability
of the remaining terms and provisions of this Agreement shall not in any way be affected or impaired thereby and the parties will attempt to agree upon a valid and enforceable provision that is a reasonable substitute therefor, and upon so agreeing,
shall incorporate such substitute provision in this Agreement. 

  
 16 

 5.14 Interpretation. The parties agree that each of them and/or their respective counsel
has reviewed and had an opportunity to revise this Agreement and, therefore, the normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not be employed in the interpretation of this
Agreement or any amendments hereto. In addition, each and every reference to share prices and shares of capital stock in this Agreement shall be subject to adjustment for reverse and forward stock splits, stock dividends, stock combinations and
other similar transactions of the Common Stock that occur after the date of this Agreement. The word “including”, whenever used in this Agreement, shall be deemed to be followed by the phrase “without limitation”. 

5.15 Replacement of Securities. If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the
Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction. The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the
issuance of such replacement Securities. 
 5.16 Independent Nature of Purchasers’ Obligations and Rights. The obligations of
each Purchaser under any Transaction Agreement are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser
under any Transaction Agreement. Nothing contained herein or in any other Transaction Agreement, and no action taken by any Purchaser pursuant hereto or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint
venture or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Agreements. Each Purchaser shall be
entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Agreements, and it shall not be necessary for any other Purchaser to be joined as an
additional party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Agreements. 

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

Authentidate Holding Corp.

dated as of May 29, 2015 

This Amendment No. 2 to the Securities Purchase Agreement and Registration Rights Agreement is effective as of the 25th day of September, 2015 (the “Second Amendment Agreement”), and is made by and among Authentidate Holding Corp., a Delaware corporation (the “Company”) and those persons and
entities executing the signature pages to this Second Amendment Agreement (the “Purchasers”). 
 W I T N E S S E T H: 

WHEREAS, the Company, the Purchasers and certain other entities are parties to that certain Securities Purchase Agreement, dated as of
May 29, 2015 (the “Purchase Agreement”) and that certain Registration Rights Agreement dated as of May 29, 2015 (“RRA”) ; 

WHEREAS, the Purchasers and other signatories to the Purchase Agreement have purchased an aggregate principal amount of $900,000 of Securities
(as defined in the Purchase Agreement) pursuant to the Purchase Agreement; and 
 WHEREAS, the Purchasers and certain of the signatories to
the Purchase Agreement and RRA have entered into that certain Amendment No. 1 to the Purchase Agreement and RRA dated as of July 7, 2015 and executed July 30, 2015; and 

WHEREAS, Section 5.6 of the Purchase Agreement provides that the Purchase Agreement may be amended upon the written consent of the
Company and the Purchasers holding a Majority in Interest (as defined therein) of the Debentures and Warrants issued pursuant to the Purchase Agreement; 

WHEREAS, Section 6(c) of the RRA provides that the RRA may be amended upon the written consent of the Company and the Holders (as defined
in the RRA) of 51% or more of the Registrable Securities (as defined in the RRA); and 
 WHEREAS, in connection with the consummation of the
transactions contemplated in the Purchase Agreement, the Company and Purchasers desire to amend the Purchase Agreement and the RRA as provided for herein; 

NOW, THEREFORE, in consideration of the premises and of the mutual covenants, agreements, representations and warranties herein contained, the
parties hereto do hereby agree as follows: 
 1. Definitions. As used herein, terms not otherwise defined in this Second Amendment
Agreement shall have the meaning ascribed to such terms as set forth in the Purchase Agreement or the RRA, as the case may be. 

  
 1 

 2. Amendments. 

(a) Section 4.13 of the Purchase Agreement is hereby amended and restated in its entirety to read as follows: 

4.13 Shareholder Approval. Solely in the event that the Company determines that it is required in order to permit the full conversion
of the Debentures (including in connection with the payment of interest thereon) or the full exercise of the Warrants issued pursuant to this Agreement into shares of Common Stock in accordance with applicable listing rules of the Principal Market
(the “Shareholder Approval”), the Company shall hold a special meeting of shareholders (which may also be at the annual meeting of shareholders) as soon as reasonably practicable, but in no event later than January 31, 2016,
for the purpose of obtaining Shareholder Approval, with the recommendation of the Company’s Board of Directors that such proposal be approved, and the Company shall solicit proxies from its shareholders in connection therewith in the same
manner as all other management proposals in such proxy statement and all management-appointed proxyholders shall vote their proxies in favor of such proposal. If the Company does not obtain Shareholder Approval at the first special meeting, the
Company shall call a meeting every three months thereafter to seek Shareholder Approval until the earlier of the date Shareholder Approval is obtained or the Debentures are no longer outstanding. Each Purchaser further agrees that it shall not be
entitled to vote the shares of Common Stock of the Company issuable to it pursuant to the terms of this Agreement, including pursuant to the conversion of the Debentures or exercise of any Warrants, at any meeting of the Company’s stockholders
convened to vote on a proposal to enable the Company to issue the Underlying Shares in excess of 19.99% of the issued and outstanding Common Stock of the Company. 

(b) Section 4.19 of the Purchase Agreement is hereby amended by adding the following text at the end thereof: 

“Notwithstanding the foregoing, however, the provisions of Section 4.19 shall not apply to any change in the Chief Executive Officer
of the Company that is made in connection with any mergers, acquisitions or other transaction resulting in a change in control of the Company, which are approved by a majority of the disinterested directors of the Company.” 

(c) The definition of Filing Date in the RRA is hereby amended and restated in its entirety to read as follows: 

“Filing Date” means, (i) with respect to the Initial Registration Statement required hereunder, February 17, 2016;
and, (ii) with respect to any additional Registration Statements which may be required pursuant to Section 2(c) or Section 3(c), the earliest practical date on which the Company is permitted by SEC Guidance to file such additional
Registration Statement related to the Registrable Securities. 
 3. Effect. Except as modified by this Second Amendment Agreement,
all other terms and conditions of the Purchase Agreement and the RRA (each as previously amended to date) remain in full force and effect. As of the effective date of this Second Amendment Agreement, (i) the applicable portions of this Second
Amendment Agreement shall be a part of the Purchase Agreement and RRA, as the case may be, each as previously amended and amended hereby, and (ii) each reference in the Purchase Agreement and the RRA or any of the Transaction Documents to
“the Purchase Agreement” or “the Registration Rights Agreement”, shall mean and be a reference to the Purchase Agreement and the RRA, as the case may be, each as previously amended and as amended hereby. 

  
 2 

 4. Miscellaneous. 

(a) This Second Amendment Agreement shall be governed by and construed in accordance with the laws of the state of New York without reference
to principles of conflicts of law. 
 (b) Headings used herein are for convenience of reference only and shall not affect the meaning
of this Second Amendment Agreement. This Second Amendment Agreement may be executed in any number of counterparts, and by the parties hereto on separate counterparts, each of which shall be an original and all of which taken together shall
constitute one and the same agreement. Executed counterparts may be delivered via facsimile or other means of electronic transmission. 

(c) Each Purchaser executing this Second Amendment Agreement hereby represents that it is the owner of the Debentures and Warrants issued to
it pursuant to the Purchase Agreement and that neither such Debentures nor such Warrants have been assigned, pledged or otherwise transferred. Each Purchaser agrees that this Second Amendment Agreement shall be affixed by it to the Purchase
Agreement and the RRA and become a part thereof. 
 (d) This Second Amendment Agreement contains the entire agreement and understanding of
the parties with respect to its subject matter and supersedes all prior arrangements and understandings between the parties, written or oral, with respect to its subject matter. This Second Amendment Agreement may not be amended or modified except
in writing signed by each of the parties to this Second Amendment Agreement. The observance of any term of this Second Amendment Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) by the
party or parties waiving compliance. The failure of any party at any time or times to require performance of any provision hereof shall in no manner affect the rights at a later time to enforce the same. No waivers of or exceptions to any term,
condition, or provision of this Second Amendment Agreement, in any one or more instances, shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition, or provision. This Second Amendment Agreement shall be
binding upon and shall inure to the benefit of and be binding upon all parties to the Purchase Agreement and the RRA and their respective successors and assigns.
