with respect to the sale of such Registrable Securities is declared effective by the Commission under the Securities Act and such Registrable Securities have been disposed of by the Holder in accordance with such effective Registration Statement,
(ii) such Registrable Securities have been previously sold in accordance with Rule 144, or (iii) such securities become eligible for resale without volume or manner-of-sale restrictions and without current public information pursuant to

“SEC Guidance” means (i) any publicly-available written or oral guidance of the Commission staff, or any comments,

 2. Required Registration. 

(a) On or prior to each Filing Date, the Company shall prepare and file with the Commission a Registration Statement covering the resale of
all of the Registrable Securities that are not then registered on an effective Registration Statement for an offering to be made on a continuous basis pursuant to Rule 415. The number of Registrable Securities that the Company will include in the
Initial Registration Statement shall cover the Initial Required Registration Amount, which is 125% of the sum of (i) the maximum number of shares of Common Stock issuable upon conversion of the Debentures at the initial conversion price thereof
and (ii) the maximum number of shares of Common Stock issuable upon exercise of the Warrants, and all subject to adjustment as provided in Section 2(c). Each Registration Statement filed hereunder shall be on Form S-3 (except if the
Company is not then eligible to register for resale the Registrable Securities on Form S-3, in which case such registration shall be on another appropriate form in accordance herewith, subject to the provisions of Section 2(e)) and shall
contain (unless otherwise directed by at least a Majority in Interest of the Holders) substantially the “Plan of Distribution” attached hereto as Annex A. Subject to the terms of this Agreement, the Company shall use its
commercially reasonable efforts to cause a Registration Statement filed under this Agreement (including, without limitation, under Section 3(c)) to be declared effective under the Securities Act as promptly as possible after the filing thereof,
but in any event no later than the applicable Effectiveness Date, and shall use its commercially reasonable efforts to keep such Registration Statement continuously effective under the Securities Act until the earlier of (i) the date that all
Registrable Securities covered by such Registration Statement no longer constitute Registrable Securities or (ii) the two year anniversary of the date of this Agreement (the “Effectiveness Period”). The Company shall
telephonically request effectiveness of a Registration Statement as of 5:00 p.m. Eastern Time on a Trading Day. The Company shall promptly notify the Holders via facsimile or by e-mail of the effectiveness of a Registration Statement on the same
Trading Day that the Company telephonically confirms effectiveness with the Commission, which shall be the date requested for effectiveness of such Registration Statement. The Company shall, by 9:30 a.m. Eastern Time on the Trading Day after the
effective date of such Registration Statement, file a final Prospectus with the Commission as required by Rule 424. 
 (b) Notwithstanding
the registration obligations set forth in Section 2(a), if the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a
single registration statement, the Company agrees to promptly inform each of the Holders thereof and use its commercially reasonable efforts to file amendments to the Initial Registration Statement as required by the Commission, covering the maximum
number of Registrable Securities permitted to be registered by the Commission, on Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering, subject to the provisions of Section 2(e); with
respect to filing on Form S-3 or other appropriate form; provided, however, that prior to filing such amendment, the Company shall be obligated to use diligent efforts to advocate with the Commission for the registration of all of the
Registrable Securities in accordance with the SEC Guidance, including without limitation, Compliance and Disclosure Interpretation 612.09. 

  
 3 








 (c) Notwithstanding any other provision of this Agreement, if the Commission or any SEC Guidance
sets forth a limitation on the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for
the registration of all or a greater portion of Registrable Securities), unless otherwise (i) directed in writing by a Holder as to its Registrable Securities, or (ii) directed by the Commission as to the limitations or restrictions that
it would require, the number of Registrable Securities to be registered on such Registration Statement will be reduced as follows: 
  

	 	a.	First, the Company shall reduce or eliminate any securities to be included by any Person other than a Holder; 

  

	 	b.	Second, the Company shall reduce or eliminate Registrable Securities contemplated by clause (c) of the definition of Registrable Securities (applied, in the case that only some such Registrable Securities may be
registered, to the Holders on a pro rata basis based on the total number of such unregistered Registrable Securities held by such Holders); and 

  

	 	c.	Third, the Company shall reduce Registrable Securities represented by Warrant Shares (applied, in the case that only some such Registrable Securities may be registered, to the Holders on a pro rata basis based on the
total number of such unregistered Registrable Securities held by such Holders); and 

  

	 	d.	Fourth, the Company shall reduce Registrable Securities represented by Conversion Shares (applied, in the case that some Conversion Shares may be registered, to the Holders on a pro rata basis based on the total number
of unregistered Conversion Shares held by such Holders). 

 In the event of a cutback hereunder, the Company shall give the
Holder at least five (5) Trading Days prior written notice along with the calculations as to such Holder’s allotment. In the event the Company amends the Initial Registration Statement in accordance with the foregoing, or determines to
file an additional Registration Statement, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general,
one or more Registration Statements on Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Initial Registration Statement, as amended, as a result of any cutback of
Registrable Securities of the Holders or any Registrable Securities not included in the Initial Registration Statement. In any additional Registration Statement filed because of a cutback in the number of Registrable Securities included in the
Initial Registration Statement, all holders of shares of Common Stock included in such additional Registration Statement shall be subject to any additional cutbacks that may be required by the Commission on a pro rata basis. 

(d) If: (i) the Initial Registration Statement is not filed on or prior to its Filing Date, or (ii) the Company fails to file with
the Commission a request for acceleration of a Registration Statement in accordance with Rule 461 promulgated by the Commission pursuant to the Securities Act, within five Trading Days of the date that the Company is notified (orally or in writing,
whichever is earlier) by the Commission that such Registration Statement will not be “reviewed” or will not be subject to further review, or (iii) a Registration Statement registering for resale all of the Initial Required
Registration Amount is not declared effective by the Commission by the Effectiveness Date of the Initial Registration Statement, or (iv) after the effective date of a Registration Statement, the Holders are not permitted to utilize the
Prospectus therein to resell such Registrable Securities, for more than thirty (30) consecutive calendar days or more than an aggregate of sixty (60) calendar days (which need not be consecutive


  
 4 








 
calendar days) during any 12-month period (any such failure or breach being referred to as an “Event”, and for purposes of clauses (i) and (iii), the date on which such
Event occurs, and for purpose of clause (ii) the date on which such five (5) Trading Day period is exceeded, and for purpose of clause (iv) the date on which such thirty (30) or sixty (60) calendar day period, as applicable,
is exceeded being referred to as “Event Date”), then, in addition to any other rights the Holders may have hereunder or under applicable law, on each such Event Date and on each monthly anniversary of each such Event Date (if the
applicable Event shall not have been cured by such date) until the applicable Event is cured, the Company shall pay to each Holder an amount in cash, as partial liquidated damages and not as a penalty, equal to the product of (1) the product of
(A) 1.0% multiplied by (B) the quotient of (I) the number of such Holder’s Registrable Securities that are not then covered by a Registration Statement that is then effective and available for use by such Holder divided by (II)
the total number of such Holder’s Registrable Securities multiplied by (2) the aggregate purchase price paid for such Holder’s Registrable Securities pursuant to the Purchase Agreement; provided, however, that, in the
event that none of such Holder’s Registrable Securities are then covered by a Registration Statement that is effective and available for use by such Holder, the quotient of (I) divided by (II) in this clause (1)(B)(X) herein shall be
deemed to equal 1. 
 The parties agree that the maximum aggregate liquidated damages payable to a Holder under this Agreement shall be 6%
of the aggregate Subscription Amount paid by such Holder pursuant to the Purchase Agreement with respect to any Registrable Securities related to the Debentures and the Warrants. The partial liquidated damages pursuant to the terms hereof shall
apply on a daily pro rata basis for any portion of a month prior to the cure of an Event. Furthermore, if an Event occurs (or is continuing) on a date more than six months after the Holder acquired the Registrable Securities (and thus the six month
holding period under Rule 144(d) has elapsed), liquidated damages shall be paid only with respect to that portion of the Holder’s Registrable Securities that cannot then be immediately resold in reliance on Rule 144.Further, amounts payable as
liquidated damages to each Holder hereunder with respect to each share of Registrable Securities shall cease when the Purchaser no longer holds such shares of Registrable Securities. No Event shall be deemed to occur or continue if such Registration
Event is caused by delays which are solely attributable to (i) the failure of a Holder to timely advise the Company of any information regarding such Holder for inclusion in the Registration Statement, but any such failure shall apply only to
that particular Holder, or (ii) the resolution of comments from the Commission pertaining to the Holders. 
 For the purposes of
clarity, it is hereby agreed that no liquidated damages shall accrue or be due in the event that the Prospectus included in any Registration Statement contemplated by this Registration Rights Agreement is suspended or otherwise unavailable for up to
the (i) 30 consecutive day period or (ii) 45 days in total during any twelve month period, as provided for above (such 30 consecutive and 45 total day periods may be referred to herein as an “Allowed Delay”). 

(e) No liquidated damages shall accrue as to any Registrable Securities that are subject to a cut- back pursuant to Section 2(c)
(“Cut Back Shares”) until such date as the Company is able to effect the registration of such Cut Back Shares in accordance with any restrictions required by the Commission. From and after the date that such restrictions are
terminated, all of the provisions of this Section 2 (including the liquidated damages provisions) shall again be applicable to such Cut Back Shares; provided, however, that the Filing Date and Effectiveness Date for the Registration Statement
including such Cut Back Shares shall be based on the termination date of such restrictions. 
 (f) If Form S-3 is not available for the
registration of the resale of Registrable Securities hereunder, the Company shall (i) register the resale of the Registrable Securities on another appropriate form and (ii) undertake to register the Registrable Securities on Form S-3 as
soon as such form is available, if at all, during the Effectiveness Period; provided that the Company shall only be required to 

  
 5 








 
maintain the effectiveness of the Registration Statement then in effect until the earlier of (A) such time as a Registration Statement on Form S-3 covering the Registrable Securities has
been declared effective by the Commission or (B) the expiration of the Effectiveness Period. 
 3. Registration Procedures. 

(A) Company Obligations. In connection with the Company’s registration obligations hereunder, the Company shall: 

(a) Not less than five (5) Trading Days prior to the filing of each Registration Statement and not less than two (2) Trading Days
prior to the filing of any related Prospectus or any amendment or supplement thereto (including any document that would be incorporated or deemed to be incorporated therein by reference), the Company shall (i) furnish to each Holder copies of
all such documents proposed to be filed, which documents (other than those incorporated or deemed to be incorporated by reference) will be subject to the review of such Holders, and (ii) cause its officers and directors, counsel and independent
registered public accountants to respond to such inquiries as shall be necessary, in the reasonable opinion of respective counsel to each Holder, to conduct a reasonable investigation within the meaning of the Securities Act. Notwithstanding the
above, the Company shall not be obligated to provide the Holders advance copies of any universal shelf registration statement registering securities in addition to those required hereunder, or any Prospectus prepared thereto. The Company shall not
file a Registration Statement or any such Prospectus or any amendments or supplements thereto to which the Holders of a majority of the Registrable Securities shall reasonably object in good faith, provided that, the Company is notified of such
objection in writing no later than three (3) Trading Days after the Holders have been so furnished copies of a Registration Statement or one (1) Trading Day after the Holders have been so furnished copies of any related Prospectus or
amendments or supplements thereto. 
 (b) (i) Prepare and file with the Commission such amendments, including post-effective
amendments, to a Registration Statement and the Prospectus used in connection therewith as may be necessary to keep a Registration Statement continuously effective as to the applicable Registrable Securities for the Effectiveness Period and prepare
and file with the Commission such additional Registration Statements in order to register for resale under the Securities Act all of the Registrable Securities, (ii) cause the related Prospectus to be amended or supplemented by any required
Prospectus supplement (subject to the terms of this Agreement), and, as so supplemented or amended, to be filed pursuant to Rule 424, (iii) respond as promptly as reasonably possible to any comments received from the Commission with respect to
a Registration Statement or any amendment thereto, and (iv) comply in all material respects with the applicable provisions of the Securities Act and the Exchange Act with respect to the disposition of all Registrable Securities covered by a
Registration Statement during the applicable period in accordance (subject to the terms of this Agreement) with the intended methods of disposition by the Holders thereof set forth in such Registration Statement as so amended or in such Prospectus
as so supplemented. 
 (c) If during the Effectiveness Period, the number of Registrable Securities at any time exceeds 100% of the number
of shares of Common Stock then registered in a Registration Statement, then the Company shall file as soon as reasonably practicable, but in any case prior to the applicable Filing Date (which date shall be subject to any applicable SEC Guidance or
limitation required by the Commission), an additional Registration Statement covering the resale by the Holders of not less than the number of such Registrable Securities. 

(d) Notify the Holders of Registrable Securities to be sold (which notice shall, pursuant to clauses (iii) through (vi) hereof, be
accompanied by an instruction to suspend the use of the Prospectus until the requisite changes have been made) as promptly as reasonably possible (i)(A) when a Prospectus 

  
 6 








 
or any Prospectus supplement or post-effective amendment to a Registration Statement has been filed, (B) when the Commission notifies the Company whether there will be a “review”
of such Registration Statement, and (C) with respect to a Registration Statement or any post-effective amendment, when the same has become effective, (ii) of any request by the Commission or any other federal or state governmental
authority for amendments or supplements to a Registration Statement or Prospectus or for additional information, in each case, after the such Registration Statement has been declared effective, (iii) of the issuance by the Commission or any
other federal or state governmental authority of any stop order suspending the effectiveness of a Registration Statement covering any or all of the Registrable Securities or the initiation of any Proceedings for that purpose, (iv) of the
receipt by the Company of any notification with respect to the suspension of the qualification or exemption from qualification of any of the Registrable Securities for sale in any jurisdiction, or the initiation or threatening of any Proceeding for
such purpose, (v) of the occurrence of any event or passage of time that makes the financial statements included in a Registration Statement ineligible for inclusion therein or any statement made in a Registration Statement or Prospectus or any
document incorporated or deemed to be incorporated therein by reference untrue in any material respect or that requires any revisions to a Registration Statement, Prospectus or other documents so that, in the case of a Registration Statement or the
Prospectus, as the case may be, it will not contain any 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, in light of the circumstances under which they
were made, not misleading, and (vi) of the occurrence or existence of any pending corporate development with respect to the Company that the Company believes may be material and that, in the determination of the Company, makes it not in the
best interest of the Company to allow continued availability of a Registration Statement or Prospectus, provided, however, in no event shall any such notice contain any information which would constitute material, non-public
information regarding the Company or any of its Subsidiaries. 
 (e) Use its commercially reasonable efforts to avoid the issuance of, or,
if issued, obtain the withdrawal of (i) any order stopping or suspending the effectiveness of a Registration Statement, or (ii) any suspension of the qualification (or exemption from qualification) of any of the Registrable Securities for
sale in any jurisdiction, at the earliest practicable moment. 
 (f) Furnish to each Holder, without charge, at least one conformed copy of
each such Registration Statement and each amendment thereto, including financial statements and schedules, all documents incorporated or deemed to be incorporated therein by reference to the extent requested by such Person, and all exhibits to the
extent requested by such Person (including those previously furnished or incorporated by reference) promptly after the filing of such documents with the Commission; provided, that any such item which is available on the EDGAR system (or successor
thereto) need not be furnished. 
 (g) The Company shall provide reasonable cooperation with any broker-dealer through which a Holder
proposes to resell its Registrable Securities in effecting a filing with the FINRA Corporate Financing Department pursuant to FINRA Rule 5110, as requested by any such Holder. 

(h) Prior to any resale of Registrable Securities by a Holder, use its commercially reasonable efforts to register or qualify or cooperate
with the selling Holders in connection with the registration or qualification (or exemption from the Registration or qualification) of such Registrable Securities for the resale by the Holder under the securities or Blue Sky laws of such
jurisdictions within the United States as any Holder reasonably requests in writing, to keep each registration or qualification (or exemption therefrom) effective during the Effectiveness Period and to do any and all other acts or things reasonably
necessary to enable the disposition in such jurisdictions of the Registrable Securities covered by each Registration Statement; provided, that, the Company shall not be required to qualify generally to do business in any jurisdiction where it is not
then so qualified, subject the Company to any material tax in any such jurisdiction where it is not then so subject or file a general consent to service of process in any such jurisdiction. 

  
 7 








 (i) If requested by a Holder, cooperate with such Holder to facilitate the timely preparation and
delivery of certificates representing Registrable Securities to be delivered to a transferee pursuant to a Registration Statement, which certificates shall be free, to the extent permitted by the Purchase Agreement, of all restrictive legends, and
to enable such Registrable Securities to be in such denominations and registered in such names as any such Holder may request. 
 (j) Upon
the occurrence of any event contemplated by clause (v) or (vi) of Section 3(A)(d), as promptly as reasonably possible under the circumstances taking into account the Company’s good faith assessment of any adverse consequences to
the Company and its stockholders of the premature disclosure of such event, prepare a supplement or amendment, including a post-effective amendment, to a Registration Statement or a supplement to the related Prospectus or any document incorporated
or deemed to be incorporated therein by reference, and file any other required document so that, as thereafter delivered, neither a Registration Statement nor such Prospectus will contain an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Holders in accordance with clauses (iii) through
(vi) of Section 3(A)(d) above to suspend the use of any Prospectus until the requisite changes to such Prospectus have been made, then the Holders shall suspend use of such Prospectus. The Company will use its commercially reasonable
efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. 
 (k) Comply with all applicable rules and
regulations of the Commission. 
 (l) The Company may require each selling Holder to furnish to the Company a certified statement as to the
number of shares of Common Stock beneficially owned by such Holder and, if required by the Commission, the natural persons thereof that have voting and dispositive control over the shares. During any periods that the Company is unable to meet its
obligations hereunder with respect to the registration of the Registrable Securities solely because any Holder fails to furnish such information within three Trading Days of the Company’s request, any liquidated damages that are accruing at
such time shall be tolled and any Event that may otherwise occur solely because of such delay shall be suspended until such information is delivered to the Company. 

B. Obligations of the Holders. 

(a) Each Holder agrees to furnish to the Company a completed questionnaire in the form attached to this Agreement as Annex B (a
“Selling Stockholder Questionnaire”) on a date that is not less than ten (10) days prior to the Filing Date or by the end of the fourth (4th) Trading Day following the
date on which such Holder receives draft materials in accordance with this Section. Each Holder shall furnish in writing to the Company such additional information regarding itself, the Registrable Securities held by it and the intended method of
disposition of the Registrable Securities held by it, as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in connection with such registration as the Company may reasonably
request. A Holder shall provide such information to the Company at least two (2) Business Days prior to the first anticipated filing date of such Registration Statement if such Holder elects to have any of the Registrable Securities included in
the Registration Statement. The Company shall not be required to include the Registrable Securities of a Holder in a Registration Statement and shall not be required to pay any liquidated or other damages hereunder to such Holder who fails to
furnish to the Company a fully completed selling holder questionnaire at least two Business Days prior to the Filing Date. 

  
 8 








 (b) Each Holder agrees to cooperate with the Company as reasonably requested by the Company in
connection with the preparation and filing of a Registration Statement hereunder, unless such Holder has notified the Company in writing of its election to exclude all of its Registrable Securities from such Registration Statement. 

(c) Each Holder covenants and agrees that it will comply with the prospectus delivery requirements of the Securities Act as applicable to it
(unless an exemption therefrom is available) in connection with sales of Registrable Securities pursuant to a Registration Statement. 
 (d)
Each Holder agrees that, upon receipt of any notice from the Company of either (i) the commencement of an Allowed Delay or (ii) the happening of an event pursuant to Section 3(A)(d)(iii) – (vi) hereof, such Holder will
immediately discontinue disposition of Registrable Securities pursuant to the Registration Statement covering such Registrable Securities, until it is advised in writing (the “Advice”) by the Company that the use of the applicable
Prospectus (as it may have been supplemented or amended) may be resumed. The Company will use its commercially reasonable efforts to ensure that the use of the Prospectus may be resumed as promptly as is practicable. 

4. Registration Expenses. All fees and expenses incident to the performance of or compliance with, this Agreement by the Company shall
be borne by the Company whether or not any Registrable Securities are sold pursuant to a Registration Statement. The fees and expenses referred to in the foregoing sentence shall include, without limitation, (i) all registration and filing fees
(including, without limitation, fees and expenses of the Company’s counsel and independent registered public accountants) (A) with respect to filings made with the Commission, (B) with respect to filings required to be made with any
Trading Market on which the Common Stock is then listed for trading, and (C) in compliance with applicable state securities or Blue Sky laws reasonably agreed to by the Company in writing (including, without limitation, fees and disbursements
of counsel for the Company in connection with Blue Sky qualifications or exemptions of the Registrable Securities), (ii) printing expenses (including, without limitation, expenses of printing certificates for Registrable Securities),
(iii) messenger, telephone and delivery expenses of the Company, (iv) fees and disbursements of counsel for the Company, (v) Securities Act liability insurance, if the Company so desires such insurance, and (vi) fees and expenses of
all other Persons retained by the Company in connection with the consummation of the transactions contemplated by this Agreement. In no event shall the Company be responsible for any broker or similar commissions of any Holder or, except to the
extent provided for in the Transaction Documents, any legal fees or other costs of the Holders. 
 5. Indemnification. 

(a) Indemnification by the Company. The Company shall, notwithstanding any termination of this Agreement, indemnify and hold harmless
each Holder, the officers, directors, members, partners, agents, brokers (including brokers who offer and sell Registrable Securities as principal as a result of a pledge or any failure to perform under a margin call of Common Stock), investment
advisors and employees of the Company, each Person who controls any such Holder (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, members, stockholders, partners,
agents, investment advisors and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable
attorneys’ fees) and expenses (collectively, “Losses”), as incurred, arising out of or relating to (1) any untrue or alleged untrue statement of a material fact contained in a Registration Statement, any Prospectus or any
form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements
therein (in the case of any Prospectus or supplement thereto, in light of the circumstances 

  
 9 








 
under which they were made) not misleading or (2) any violation or alleged violation by the Company of the Securities Act, the Exchange Act or any state securities law, or any rule or
regulation thereunder, in connection with the performance of its obligations under this Agreement, except to the extent, but only to the extent, that (i) such untrue statements or omissions are based solely upon information regarding such
Holder furnished in writing to the Company by such Holder expressly for use therein, or to the extent that such information relates to such Holder or such Holder’s proposed method of distribution of Registrable Securities and was reviewed and
expressly approved in writing by such Holder expressly for use in a Registration Statement, such Prospectus or in any amendment or supplement thereto (it being understood that the Holder has approved Annex A hereto for this purpose) or (ii) in
the case of an occurrence of an event of the type specified in Section 3(d)(iii)-(vi), the use by such Holder of an outdated, defective or otherwise unavailable Prospectus after the Company has notified such Holder in writing that the
Prospectus is outdated, defective or otherwise unavailable for use by such Holder and prior to the receipt by such Holder of the Advice contemplated in Section 3(B)(d). The Company shall notify the Holders promptly of the institution, threat or
assertion of any Proceeding arising from or in connection with the transactions contemplated by this Agreement of which the Company is aware. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf
of such indemnified person and shall survive the transfer of any Registrable Securities by any of the Holders in accordance with Section 6(e). 

(b) Indemnification by Holders. Each Holder shall, severally and not jointly, indemnify and hold harmless the Company, its directors,
officers, agents and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling Persons,
to the fullest extent permitted by applicable law, from and against all Losses, as incurred, to the extent arising out of or based solely upon: (x) such Holder’s failure to comply with any applicable prospectus delivery requirements of the
Securities Act through no fault of the Company or (y) any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any Prospectus, or in any amendment or supplement thereto or in any preliminary prospectus,
or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any Prospectus or supplement thereto, in light of the circumstances under
which they were made) not misleading (i) to the extent, but only to the extent, that such untrue statement or omission is contained in any information so furnished in writing by such Holder to the Company expressly for inclusion in such
Registration Statement or such Prospectus or (ii) to the extent, but only to the extent, that such information relates to such Holder’s proposed method of distribution of Registrable Securities and was reviewed and expressly approved in
writing by such Holder expressly for use in a Registration Statement (it being understood that the Holder has approved Annex A hereto for this purpose), such Prospectus or in any amendment or supplement thereto or (iii) in the case of an
occurrence of an event of the type specified in Section 3(d)(iii)-(vi), to the extent, but only to the extent, related to the use by such Holder of an outdated, defective or otherwise unavailable Prospectus after the Company has notified such
Holder in writing that the Prospectus is outdated, defective or otherwise unavailable for use by such Holder and prior to the receipt by such Holder of the Advice contemplated in Section 3(B)(d). In no event shall the liability of any selling
Holder under this Section 5(b) be greater in amount than the dollar amount of the net proceeds received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation, except in the case of fraud or
willful misconduct by such Holder. 
 (c) Conduct of Indemnification Proceedings. If any Proceeding shall be brought or asserted
against any Person entitled to indemnity hereunder (an “Indemnified Party”), such Indemnified Party shall promptly notify the Person from whom indemnity is sought (the “Indemnifying Party”) in writing, and the
Indemnifying Party shall have the right to assume the defense thereof, including the employment of counsel reasonably satisfactory to the Indemnified Party and the payment of all reasonable fees and expenses incurred in connection with defense
thereof; provided, that, the failure of any Indemnified Party 

  
 10 








 
to give such notice shall not relieve the Indemnifying Party of its obligations or liabilities pursuant to this Agreement, except (and only) to the extent that it shall be finally determined by a
court of competent jurisdiction (which determination is not subject to appeal or further review) that such failure shall have materially and adversely prejudiced the Indemnifying Party. An Indemnified Party shall have the right to employ separate
counsel in any such Proceeding and to participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Indemnified Party or Parties unless: (1) the Indemnifying Party has agreed in writing to pay
such fees and expenses, (2) the Indemnifying Party shall have failed promptly to assume the defense of such Proceeding and to employ counsel reasonably satisfactory to such Indemnified Party in any such Proceeding, or (3) the named parties
to any such Proceeding (including any impleaded parties) include both such Indemnified Party and the Indemnifying Party, and counsel to the Indemnified Party shall reasonably believe that a material conflict of interest is likely to exist if the
same counsel were to represent such Indemnified Party and the Indemnifying Party (in which case, if such Indemnified Party notifies the Indemnifying Party in writing that it elects to employ separate counsel at the expense of the Indemnifying Party,
the Indemnifying Party shall not have the right to assume the defense thereof and the reasonable fees and expenses of no more than one separate counsel shall be at the expense of the Indemnifying Party). The Indemnifying Party shall not be liable
for any settlement of any such Proceeding effected without its written consent. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any pending Proceeding in respect of which any
Indemnified Party is a party, unless such settlement includes an unconditional release of such Indemnified Party from all liability on claims that are the subject matter of such Proceeding. Subject to the terms of this Agreement, all reasonable fees
and expenses of the Indemnified Party (including reasonable fees and expenses to the extent incurred in connection with investigating or preparing to defend such Proceeding in a manner not inconsistent with this Section) shall be paid to the
Indemnified Party, as incurred, within thirty (30) calendar days of written notice thereof to the Indemnifying Party; provided, that, the Indemnified Party shall promptly reimburse the Indemnifying Party for that portion of such fees and
expenses applicable to such actions for which such Indemnified Party is finally determined by a court of competent jurisdiction (which determination is not subject to appeal or further review) not to be entitled to indemnification hereunder. 

(d) Contribution. If the indemnification under Section 5(a) or 5(b) is unavailable to an Indemnified Party or insufficient to hold
an Indemnified Party harmless for any Losses, then each Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party, in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party and
Indemnified Party in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of such Indemnifying Party and Indemnified Party shall be determined by
reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission of a material fact, has been taken or made by, or relates to information supplied
by, such Indemnifying Party or Indemnified Party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action, statement or omission. The amount paid or payable by a party as a result of
any Losses shall be deemed to include, subject to the limitations set forth in this Agreement, any reasonable attorneys’ or other fees or expenses incurred by such party in connection with any Proceeding to the extent such party would have been
indemnified for such fees or expenses if the indemnification provided for in this Section was available to such party in accordance with its terms. The parties hereto agree that it would not be just and equitable if contribution pursuant to this
Section 5(d) were determined by pro rata allocation or by any other method of allocation that does not take into account the equitable considerations referred to in the immediately preceding paragraph. Notwithstanding the provisions of this
Section 5(d), no Holder shall be required to contribute pursuant to this Section 5(d), in the aggregate, any amount in excess of the amount by which the net proceeds actually received by such Holder from the sale of the Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. 

  
 11 








 (e) The indemnity and contribution agreements contained in this Section are in addition to any
liability that the Indemnifying Parties may have to the Indemnified Parties. 
 6. Miscellaneous. 

(a) Remedies. In the event of a breach by the Company or by a Holder of any of their respective obligations under this Agreement, each
Holder or the Company, as the case may be, in addition to being entitled to exercise all rights granted by law and under this Agreement, including recovery of damages, shall be entitled to specific performance of its rights under this Agreement.
Each of the Company and each Holder agrees that monetary damages would not provide adequate compensation for any losses incurred by reason of a breach by it of any of the provisions of this Agreement and hereby further agrees that, in the event of
any action for specific performance in respect of such breach, it shall not assert or shall waive the defense that a remedy at law would be adequate. 

(b) Piggy-Back Registrations. If, at any time during the Effectiveness Period, 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 the Company’s stock option or other employee benefit plans, then the Company shall deliver to each Holder a written notice of such determination and, if within fifteen days after the date of the delivery
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. 

(c) Amendments and Waivers. The provisions of this Agreement, including the provisions of this sentence, may not be amended, modified
or supplemented, and waivers or consents to departures from the provisions hereof may not be given, unless the same shall be in writing and signed by the Company and the Holders of 51% or more of the then outstanding Registrable Securities (for
purposes of clarification, this includes any Registrable Securities issuable upon exercise or conversion of any Security). If a Registration Statement does not register all of the Registrable Securities pursuant to a waiver or amendment done in
compliance with the previous sentence, then the number of Registrable Securities to be registered for each Holder shall be reduced pro rata among all Holders and each Holder shall have the right to designate which of its Registrable Securities shall
be omitted from such Registration Statement. Notwithstanding the foregoing, a waiver or consent to depart from the provisions hereof with respect to a matter that relates exclusively to the rights of a Holder or some Holders and that does not
directly or indirectly affect the rights of other Holders may be given only by such Holder or Holders of all of the Registrable Securities to which such waiver or consent relates; provided, however, that the provisions of this sentence
may not be amended, modified, or supplemented except in accordance with the provisions of the first sentence of this Section 6(c). No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any
provision of this Agreement unless the same consideration also is offered to all of the parties to this Agreement. 
 (d) Notices.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be delivered as set forth in the Purchase Agreement. 

  
 12 








 (e) Successors and Assigns. This Agreement shall inure to the benefit of and be binding
upon the successors and permitted assigns of each of the parties and shall inure to the benefit of each Holder. The Company may not assign (except by merger) its rights or obligations hereunder without the prior written consent of all of the Holders
of the then outstanding Registrable Securities. Each Holder may assign their respective rights hereunder in the manner and to the Persons as permitted under the Purchase Agreement. 

(f) Prior Registration Rights. Each Holder of Registrable Securities hereby acknowledges that the Company has previously entered into
agreements granting registration rights with respect to currently outstanding shares of convertible preferred stock and other common stock purchase warrants, which have not yet been satisfied and that the holders of such other securities may elect
to include such shares of common stock issuable upon conversion or exercise of such securities in the Registration Statement(s) required to be filed hereunder. However, if, in the opinion of counsel for the Lead Investor, the inclusion of such
shares by other holders of the Company could reasonably be prohibited by the Commission pursuant to Rule 415 and/or related SEC Guidance, the Company will, upon the reasonable request by the Lead Investor, request such holder to refrain from
including such person’s registrable securities in the Registration Statement(s) filed pursuant to this Agreement. 
 (g) Execution
and Counterparts. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and
delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such
signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 

(h) Governing Law. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be
determined in accordance with the provisions of the Purchase Agreement. 
 (i) Cumulative Remedies. The remedies provided herein are
cumulative and not exclusive of any other remedies provided by law. 
 (j) Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and
shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such
term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed the remaining terms, provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable. 
 (k) Headings. The headings in this Agreement are for convenience only,
do not constitute a part of the Agreement and shall not be deemed to limit or affect any of the provisions hereof. 
 (l) Independent
Nature of Holders’ Obligations and Rights. The obligations of each Holder hereunder are several and not joint with the obligations of any other Holder hereunder, and no Holder shall be responsible in any way for the performance of the
obligations of any other Holder hereunder. Nothing contained herein or in any other agreement or document delivered at any closing, and no action 

  
 13 








 
taken by any Holder pursuant hereto or thereto, shall be deemed to constitute the Holders as a partnership, an association, a joint venture or any other kind of group or entity, or create a
presumption that the Holders are in any way acting in concert or as a group or entity with respect to such obligations or the transactions contemplated by this Agreement or any other matters, and the Company acknowledges that the Holders are not
acting in concert or as a group, and the Company shall not asset any such claim, with respect to such obligations or transactions. Each Holder shall be entitled to protect and enforce its rights, including without limitation the rights arising out
of this Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such purpose. The use of a single agreement with respect to the obligations of the Company contained was solely in the
control of the Company, not the action or decision of any Holder, and was done solely for the convenience of the Company and not because it was required or requested to do so by any Holder.

 Annex A 

Plan of Distribution 

Each Selling Stockholder (the “Selling Stockholders”) of the securities and any of their pledgees, assignees and
successors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal Trading Market or any other stock exchange, market or trading facility on which the securities are traded or in private transactions.
These sales may be at fixed or negotiated prices. A Selling Stockholder may use any one or more of the following methods when selling securities: 
  

	 	•	 	ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers; 

  

	 	•	 	block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction; 


 

	 	•	 	purchases by a broker-dealer as principal and resales by the broker-dealer for its account; 

  

	 	•	 	an exchange distribution in accordance with the rules of the applicable exchange; 

  

	 	•	 	privately negotiated transactions; 

  

	 	•	 	settlement of short sales; 

  

	 	•	 	in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security; 


 

	 	•	 	through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise; 

  

	 	•	 	a combination of any such methods of sale; or 

  

	 	•	 	any other method permitted pursuant to applicable law. 

 The Selling Stockholders may also sell
securities under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus. 

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive
commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case
of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2440. 

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with
broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to
close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions
or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell
pursuant to this prospectus (as supplemented or amended to reflect such transaction). 

  
 17 








 The Selling Stockholders and any broker-dealers or agents that are involved in selling the
securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities
purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. Each Selling Stockholder has informed the Company that it does not have any written or oral agreement or understanding, directly or indirectly,
with any person to distribute the securities. 
 The Company is required to pay certain fees and expenses incurred by the Company incident
to the registration of the securities. The Company has agreed to indemnify the Selling Stockholders against certain losses, claims, damages and liabilities, including liabilities under the Securities Act. 

Because Selling Stockholders may be deemed to be “underwriters” within the meaning of the Securities Act, they will be subject to
the prospectus delivery requirements of the Securities Act including Rule 172 thereunder. In addition, any securities covered by this prospectus which qualify for sale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather
than under this prospectus. The Selling Stockholders have advised us that there is no underwriter or coordinating broker acting in connection with the proposed sale of the resale securities by the Selling Stockholders. 

We agreed to keep this prospectus effective until the earlier of (i) the date on which the securities may be resold by the Selling
Stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for the Company to be in compliance with the current public information under Rule 144 under the
Securities Act or any other rule of similar effect or (ii) all of the securities have been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale securities will be sold only
through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale securities covered hereby may not be sold unless they have been registered or qualified for sale in the
applicable state or an exemption from the registration or qualification requirement is available and is complied with. 
 Under applicable
rules and regulations under the Exchange Act, any person engaged in the distribution of the resale securities may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined
in Regulation M, prior to the commencement of the distribution. In addition, the Selling Stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the
timing of purchases and sales of securities of the common stock by the Selling Stockholders or any other person. We will make copies of this prospectus available to the Selling Stockholders and have informed them of the need to deliver a copy of
this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

 Annex B 

AUTHENTIDATE HOLDING CORP. 

Selling Stockholder Notice and Questionnaire 

The undersigned beneficial owner of common stock (the “Registrable Securities”) of Authentidate Holding Corp., a Delaware
corporation (the “Company”), understands that the Company has filed or intends to file with the Securities and Exchange Commission (the “Commission”) a registration statement (the “Registration

you had no agreements or understandings, directly or indirectly, with any person to distribute the Registrable Securities?

	 	Note: 	If “no” to Section 3(d), the Commission’s staff has indicated that you should be identified as an underwriter in the Registration Statement. 


4. Beneficial Ownership of Securities of the Company Owned by the Selling Stockholder. 

Please state the number of securities of the Company beneficially owned by the Selling Stockholder, regardless of the time acquired or the
source from which derived. 
  

	 	(a)	Number of shares of Common Stock beneficially owned: 

  

			
		  	  


  

	 	(b)	Number of shares of Common Stock beneficially owned to be registered pursuant to the Registration Statement (if not the same as 4(a) above): 


 

			
		  	  


 “Beneficial ownership” of a security means a person’s ability, directly or indirectly through
any contract, arrangement, understanding, relationship or otherwise, to exercise alone or together with others: 
  

	 	•	 	voting power, which includes the power to vote, or to direct the voting of, a security; or 

  

	 	•	 	investment power, which includes the power to dispose, or to direct the disposition, of a security. 


This term also includes having the right to acquire beneficial ownership of a security within 60 days, including any right to acquire the
security through the exercise of any option, warrant or right, through the conversion of a security, pursuant to the power to revoke a trust, discretionary account or similar arrangement or pursuant to the automatic termination of a trust,
discretionary account or similar arrangement. 
 The above definition of beneficial ownership is very broad and may include, for example, securities held in
the name of another person, such as any relative living in your home, custodians, brokers, or pledgees for your account, or any partnership, trust estate or closely-held corporation in which you have an interest or are an officer or director. You
are also the beneficial owner of securities if you, directly or indirectly, create or use a trust, proxy, power of attorney, pooling arrangement or any other contract, arrangement or device with the purpose or effect of divesting yourself of
beneficial ownership of such securities or preventing the vesting of such beneficial ownership. 
 5. Voting and Investment Power (to be completed only
if the Selling Stockholder is not a natural person): 
  

	 	(a)	Please name each person or persons who have voting or investment power over the Common Stock beneficially owned by the Selling Stockholder. As described in Question 4 above, please note that for purposes of answering
this Question 5: 


  
 20 









	 	(1)	Voting power includes the power to vote, or to direct the voting of, such security; and 

  

	 	(2)	Investment power includes the power to dispose, or to direct the disposition, of such security. 

  

	
	  

	
	  

	
	  


  

	 	(b)	For each person named above in this Question 5, please state the number of shares of Common Stock beneficially owned by the Selling Stockholder in which that person has sole voting power, shared voting power, sole
investment power and/or shared investment power. 

  

			
	 	  	Number of
	 Beneficial Ownership
	  	Shares
	 Total number of shares as to which the person has sole voting power
	  	
	 Total number of shares as to which the person has shared voting power
	  	
	 Total number of shares as to which the person has sole investment power
	  	
	 Total number of shares as to which the person has shared investment power
	  	

 If necessary, use the blank page attached hereto as Exhibit B. 

 

	 	(c)	Do you have any reason to believe that the ownership of the Common Stock of the registered holder identified in response to Question 1 above should be aggregated with the ownership of any other registered holder of the
Common Stock, for purposes of describing the beneficial ownership of those shares of Common Stock in the Registration Statement? Ownership could be aggregated where there is a relationship that, as a factual matter, confers on a person a significant
ability to affect how voting power or investment power over the shares will be exercised.
