 THIS EIGHTH SUPPLEMENTAL INDENTURE (this “Eighth Supplemental
Indenture”) is made as of the 10th day of June, 2013,
by and between AFLAC INCORPORATED, a Georgia corporation, as issuer (the “Company”), and THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., a national banking association, as trustee (the “Trustee”): 

WHEREAS, the Company has heretofore entered into a Senior Indenture, dated as of May 21, 2009 (the “Original Indenture”),
with the Trustee; 
 WHEREAS, the Original Indenture is incorporated herein by reference, and the Original Indenture, as
supplemented by this Eighth Supplemental Indenture, is herein called the “Indenture”; 
 WHEREAS, under the Original
Indenture, a new series of senior notes may at any time be established by the Board of Directors of the Company in accordance with the provisions of the Original Indenture and the terms of such series may be described by a supplemental indenture
executed by the Company and the Trustee; 
 WHEREAS, the Company proposes to create under the Indenture a new series of senior
notes; 
 WHEREAS, additional senior notes of other series hereafter established, except as may be limited in the Original
Indenture as at the time supplemented and modified, may be issued from time to time pursuant to the Indenture as at the time supplemented and modified, and all senior notes issued by the Company of any one series need not be issued at the same time
and, unless otherwise so provided, may be reopened for issuances of additional senior notes of such series; and 
 WHEREAS, all
things necessary to authorize the execution and delivery of this Eighth Supplemental Indenture and make it a valid and binding agreement of the Company, in accordance with its terms, have been done. 

 NOW THEREFORE, in consideration of the agreements and obligations set forth herein and for
other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows: 
 ARTICLE I 
 3.625% SENIOR NOTES DUE 2023 

Section 1.01 Establishment. There is hereby established a new series of senior notes to be issued under the Indenture, to be designated as the
Company’s 3.625% Senior Notes due 2023 (the “Senior Notes”). 
 There are to be authenticated and delivered
Senior Notes, initially limited in aggregate principal amount to $700,000,000 and no further Senior Notes shall be authenticated and delivered except as provided by Section 2.8, 2.9, 2.11, 8.5 or 12.3 of the Original Indenture and the terms of
this Eighth Supplemental Indenture; provided, however, that the Company may re-open this series of Senior Notes and the aggregate principal amount of the Senior Notes may be increased in the future, without the consent of the holders of the Senior
Notes, with the same ranking, interest rate, maturity date and other terms and with the same CUSIP and ISIN numbers as the Senior Notes other than with respect to: (i) the date of issuance, (ii) the issue price and (iii) the date from
which interest shall accrue and the amount of interest payable on the first Interest Payment Date following the issuance of any such additional Senior Notes (which terms shall be set forth in a Board Resolution accompanying the Order pursuant to
which any such additional Senior Notes are authenticated). Any such additional Senior Notes and the Senior Notes established pursuant hereto shall be considered collectively as a single class for all purposes of the Indenture. The Senior Notes shall
be issued in fully registered form. 
 The Senior Notes shall be issued in the form of one or more Global Securities (as defined
below) in substantially the form set out in Exhibit A hereto. 
 The form of the Trustee’s Certificate of Authentication
for the Senior Notes shall be substantially in the form set forth in Exhibit B hereto. 
 Each Senior Note shall be dated the
date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for. 

Section 1.02 Definitions. The following defined terms used herein shall, unless the context otherwise requires, have the meanings specified below.
Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Original Indenture. 
 “Global Security” means, with respect to any series of securities, a security authenticated and delivered under the Original Indenture executed by the Company and held by the Trustee as
custodian for the Depositary, all in accordance with the Original Indenture, which shall be registered in the name of the Depositary or its nominee. 

  
 2 

 “Interest Payment Date” means June 15 and December 15 of each year,
commencing on December 15, 2013. 
 “Regular Record Date” means, with respect to each Interest Payment Date, the
close of business on June 1 or December 1 immediately preceding such Interest Payment Date. 
 “Stated
Maturity” means June 15, 2023. 
 Section 1.03 Payment of Principal and Interest. The principal of the Senior Notes shall be
due at Stated Maturity. The unpaid and outstanding principal amount of the Senior Notes, and any overdue installment of interest thereon to the extent permitted by law, shall bear interest at the rate of 3.625% per year until paid or made
available for payment, such interest to accrue from the most recent Interest Payment Date on which interest has been paid or duly provided for or, if no interest has been paid, from June 10, 2013. Interest shall be paid semi-annually in arrears
on each Interest Payment Date, commencing on December 15, 2013, to the Person in whose name the Senior Notes are registered on the Regular Record Date for such Interest Payment Date, provided that interest payable at the Stated Maturity or on a
Redemption Date (as defined below) as provided herein, will be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid or duly provided for will forthwith cease to be payable to the holders on such Regular
Record Date and may be paid as provided in Section 2.7 of the Original Indenture. 
 Payments of interest on the Senior
Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Senior Notes shall be computed and paid on the basis of a 360-day year consisting of twelve 30-day months. In the event that any
date on which interest is payable on the Senior Notes is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of
any such delay), except that, if such next succeeding Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the date the
payment was originally payable. 
 Payment of the principal, premium, if any, and interest due at the Stated Maturity of, or on
a Redemption Date for, the Senior Notes shall be made upon surrender of the Senior Notes at the Corporate Trust Office of the Trustee. The principal of and interest on the Senior Notes shall be paid in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and private debts. Payments of interest (including interest on any Interest Payment Date) will be made, subject to such surrender where applicable, at the option of the Company,
(i) by check mailed to the address of the Person entitled thereto as such address shall appear in the 

  
 3 

 
Security register or (ii) by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least 15 days
prior to the date for payment by the Person entitled thereto. 
 Section 1.04 Denominations. The Senior Notes will be issued only in
denominations of $2,000 and integral multiples of $1,000 in excess thereof. 
 Section 1.05 Global Securities. The Senior Notes will
initially be issued in the form of one or more Global Securities registered in the name of the Depositary (which initially shall be The Depository Trust Company (“DTC”)) or its nominee. Except under the limited circumstances described
below, Senior Notes represented by Global Securities will not be exchangeable for, and will not otherwise be issuable as, Senior Notes in definitive form. The Global Securities described above may not be transferred except by the Depositary to a
nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee. 
 Owners of beneficial interests in such Global Securities will not be considered the holders thereof for any purpose under the Indenture, and no Global Security representing a Senior Note shall be
exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee. The rights of holders of such Global Securities shall be
exercised only through the Depositary. 
 A Global Security shall be exchangeable for Senior Notes registered in the names of
Persons other than the Depositary or its nominee only as provided by Section 2.8(5) of the Original Indenture. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Senior Notes registered in such
names as the Depositary shall direct. 
 Section 1.06 Transfer. No service charge will be made for any registration of transfer or
exchange of Senior Notes, but payment will be required of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith. 
 Section 1.07 Defeasance. The provisions of Sections 10.4 and 10.5 of the Original Indenture will apply to the Senior Notes. 
 Section 1.08 Redemption at the Option of the Company. The Senior Notes will be redeemable, at the sole option of the Company, in whole at any time or in part from time to time (a “Redemption
Date”), at a redemption price (the “Redemption Price”) equal to the greater of (i) 100% of the aggregate principal amount of the Senior Notes to be redeemed and (ii) an amount equal to the sum of the present values of the
remaining scheduled payments for principal of and interest on the Senior Notes to be redeemed, not including any portion of the payments of interest accrued as of such Redemption Date, discounted to such Redemption Date on a semi-annual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 20 basis points, plus, in the case of each of (i) and (ii), accrued and unpaid interest on the principal amount of the Senior Notes to be redeemed to, but
excluding, such Redemption Date.

 “Treasury Rate” means (1) the yield, under the heading which represents the
average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System
and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no
maturity is within three months before or after the remaining life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated
from such yields on a straight line basis, rounding to the nearest month), or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year
equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such
Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date. 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term of the Senior Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable
maturity to the remaining term of the Senior Notes. 
 “Independent Investment Banker” means one of Goldman,
Sachs & Co., Mizuho Securities USA Inc. and Morgan Stanley & Co. LLC and their successors, appointed by the Company or, if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking
institution of national standing appointed by the Company. 
 “Comparable Treasury Price” means with respect to any
Redemption Date for the Senior Notes (1) the average of five Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Company obtains
fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Reference Treasury
Dealer” means each of Goldman, Sachs & Co., Mizuho Securities USA Inc. and Morgan Stanley & Co. LLC and their respective successors and two other primary U.S. government securities dealers (each a “Primary Treasury

Company will substitute therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotations” means,
with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its
principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

Notwithstanding Section 12.2 of the Original Indenture, the notice of redemption with respect to the foregoing redemption need not
set forth the Redemption Price but only the manner of calculation thereof. 
 Section 1.09 Notice to Trustee. The Company shall notify
the Trustee of the Redemption Price with respect to the foregoing redemption promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price. 

Section 1.10 Selection of Senior Notes to be Redeemed; Notice of Redemption. If less than all of the Senior Notes are to be redeemed, the Trustee
shall select, in accordance with the procedures of DTC, the principal amount of such Senior Notes to be redeemed. The Trustee may select Senior Notes and portions of Senior Notes in amounts of $2,000 and whole multiples of $1,000 in excess of
$2,000. 
 ARTICLE II

this Eighth Supplemental Indenture are made by the Company only and not by the Trustee, and the Trustee assumes no responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of this Eighth
Supplemental Indenture or of the Senior Notes. The Trustee shall not be accountable for the use or application by the Company of the Senior Notes or the proceeds thereof. All of the provisions contained in the Original Indenture in respect of the
rights, privileges, immunities, powers and duties of the Trustee shall be applicable in respect of the Senior Notes and of this Eighth Supplemental Indenture as fully and with like effect as if set forth herein in full. 

Section 2.02 Ratification and Incorporation of Original Indenture. As supplemented hereby, the Original Indenture is in all respects ratified and
confirmed, and the Original Indenture and this Eighth Supplemental Indenture shall be read, taken and construed as one and the same instrument. 

  
 6 

 Section 2.03 Executed in Counterparts. This Eighth Supplemental Indenture may be simultaneously
executed in several counterparts, each of which shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument. 
 Section 2.04 New York Law to Govern. This Eighth Supplemental Indenture and each Senior Note shall be deemed to be a contract under the laws of the state of New York, and for all purposes shall be
construed in accordance with the laws of such state, except as may be required by mandatory provisions of law.

quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

Notice of any redemption will be mailed at least 30 days but no more than 60 days before the Redemption Date to each Holder of the Senior
Notes to be redeemed. Notwithstanding Section 12.2 of the Original Indenture, the notice of redemption with respect to the foregoing redemption need not set forth the Redemption Price but only the manner of calculation thereof. 

The Company shall notify the Trustee of the Redemption Price with respect to the foregoing redemption promptly after the calculation
thereof. The Trustee shall not be responsible for calculating said Redemption Price. Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Senior Notes or portions
thereof called for redemption. 
 If less than all of the Senior Notes are to be redeemed, the Trustee shall determine, in
accordance with the procedures of DTC, the principal amount of such Senior Notes to be redeemed. The Trustee may select Senior Notes and portions of Senior Notes in amounts of $2,000 and whole multiples of $1,000 in excess of $2,000. 

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and interest on this Note at the time, place and rate, and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable in the Security register, upon surrender of this Note for registration of
transfer at the office or agency of the Company for such purpose, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company or the Security registrar and duly executed by, the holder hereof or his
attorney duly authorized in writing, and thereupon one or more new Senior Notes, of authorized denominations and of like 

  
 A-7

 
tenor and for the same aggregate principal amount, will be issued to the designated transferee or transferees. No service charge shall be made for any such exchange or registration of transfer,
but the Company will require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this Note for registration of transfer, the Company, the Trustee, any Person authorized by the Company to pay the principal of or any premium or interest on any Senior Note on
behalf of the Company (“Paying Agent”) and the Security registrar may deem and treat the Person in whose name this Note is registered as the absolute owner hereof for all purposes, whether or not this Note be overdue and notwithstanding
any notice of ownership or writing thereon made by anyone other than the Security registrar, and neither the Company nor the Trustee nor any Paying Agent nor the Security registrar shall be affected by notice to the contrary. 

The Senior Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Senior Notes are exchangeable for a like aggregate principal amount of Senior Notes of a different authorized denomination, as requested by the holder
surrendering the same upon surrender of the Senior Note or Senior Notes to be exchanged at the office or agency of the Company. 

No recourse shall be had for payment of the principal of or interest on this Note, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Indenture, against any incorporator, as such or against any past, present or future shareholder, officer or director, as such, of the Company or of any successor, either directly or through the Company or any
successor, under any rule, law statute or constitutional provision, or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released, by the acceptance hereof and as
part of the consideration for the issuance hereof. 
 Unless the certificate of authentication hereon has been executed by the
Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 
 This Note shall be governed by, and construed in accordance with, the internal laws of the state of New York.

 Exhibit 4.1 
 WARRANT AGREEMENT 
 THIS WARRANT AGREEMENT (this “Warrant
Agreement”), dated as of June     , 2013 (the “Issuance Date”), is entered into by and between Authentidate Holding Corp., a Delaware corporation (the “Company”), and Continental Stock Transfer &
Trust Company, a New York corporation (the “Warrant Agent”). 
 WHEREAS, the Company has sold units (the
“Units”), each consisting of one share of common stock, par value $0.001 per share (the “Common Stock”), of the Company and one warrant to purchase one share of Common Stock at an exercise price of $0.95 per share (each, a
“Warrant Share” and, collectively, the “Warrant Shares”) subject to adjustment as described herein (each, a “Warrant” and, collectively, the “Warrants”), pursuant to an Underwriting Agreement between the
Company and J. P. Turner & Co., L.L.C., as the Underwriter, dated June 11, 2013 (the “Underwriting Agreement”); and 
 WHEREAS, both the Common Stock and the Warrants underlying the Units were issued by the Company in a public offering pursuant to an effective shelf registration statement on Form S-3, Registration
No. 333-183093 (the “Registration Statement”) filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”), and a related base prospectus and
prospectus supplement; and 
 WHEREAS, the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant
Agent is willing to so act, in connection with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants; 
 WHEREAS, the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and
immunities of the Company, the Warrant Agent, and the holders of the Warrants; and 
 WHEREAS, all acts and things have been
done and performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided herein, the valid, binding and legal obligations of the Company, and to authorize
the execution and delivery of this Agreement. 
 NOW, THEREFORE, in consideration of the mutual agreements herein contained, the
parties hereto agree as follows: 
 1. Appointment of Warrant Agent. The Company hereby appoints the Warrant Agent to act as agent for
the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. 
 2. Warrants. 
 2.1 Form of Warrant. Each Warrant shall be
(a) issued in registered form only, (b) in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein, and (c) signed by, or bear the facsimile signature of the Chief Executive Officer,
President, Chief 

 
Financial Officer, or the Secretary of the Company. In the event the person whose facsimile signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such
person signed the Warrant before such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance. 
 2.2 Effect of Countersignature. Unless and until countersigned by the Warrant Agent pursuant to this Warrant Agreement, a Warrant shall be invalid and of no effect and may not be exercised by the
holder thereof. 
 2.3 Registration. 
 2.3.1 Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the registration of the original issuance and transfers of the Warrants. Upon the initial
issuance of the Warrants, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. The
Warrants may be represented by definitive Warrant Certificates in physical form or by one or more book-entry warrant certificates (the “Book-Entry Warrant Certificates”) deposited with the Depository Trust Company (the
“Depository”) and registered in the name of Cede & Co., a nominee of the Depository. Ownership of beneficial interests in the Book-Entry Warrant Certificates shall be shown on, and the transfer of such ownership shall be effected
through, records maintained (i) by the Depository or its nominee for each Book-Entry Warrant Certificate; (ii) by institutions that have accounts with the Depository (such institution, with respect to a Warrant in its account, a
“Participant”); or (iii) directly on the book-entry records of the Warrant Agent with respect only to owners of beneficial interests that request such direct registration. If the Depository subsequently ceases to make its book-entry
settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making other arrangements for book-entry settlement within ten (10) days after the Depository ceases to make its book-entry settlement available.
In the event that the Company does not make alternative arrangements for book-entry settlement within ten (10) days or the Warrants are not eligible for, or it is no longer necessary to have the Warrants available in, book-entry form, the
Warrant Agent shall provide written instructions to the Depository to deliver to the Warrant Agent for cancellation each Book-Entry Warrant Certificate, and the Company shall instruct the Warrant Agent to deliver to the Depository definitive Warrant
Certificates in physical form evidencing such Warrants. 
 2.3.2 Registered Holder; Beneficial Owner. Prior to due
presentment for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant shall be registered upon the Warrant Register (the “registered holder”), as the absolute
owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation of ownership or other writing on the warrant certificate made by anyone other than the Company or the Warrant Agent), for the purpose of any exercise
thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. The term “beneficial owner” shall mean any person in whose name ownership of a beneficial interest in the
Warrants evidenced by (a) a Book-Entry Warrant Certificate is recorded in the records maintained by the Depository or its nominee or (b) a definitive Warrant Certificate is recorded in the book-entry records of the Warrant Agent.

  
 2 

 2.3.3 Detachability of Warrants. The securities comprising the Units will be issued
separately and will be separately transferable immediately upon issuance.
 2.3.4 Uncertificated Warrants.
Notwithstanding the foregoing and anything else herein to the contrary, the Warrants may be issued in uncertificated form if so specified by the Company. 
 3. Terms and Exercise of Warrants. 
 3.1 Exercise Price. Each
Warrant shall, when countersigned by the Warrant Agent, entitle the registered holder thereof, subject to the provisions of such Warrant, and, as the case may be, and of this Warrant Agreement, to purchase from the Company the number of shares of
Common Stock stated therein, at the price of $0.95 per whole share, subject to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Exercise Price” as used in this Warrant Agreement
refers to the price per share at which Common Stock may be purchased at the time a Warrant is exercised. The Company, in its sole discretion, may lower the Exercise Price at any time prior to the Expiration Date (as defined below). 

3.2 Duration of Warrants. A Warrant may be exercised only during the period (“Exercise Period”) commencing on the
Issuance Date and terminating at 5:00 p.m., New York City time on June 17, 2018 (the “Expiration Date”). Each Warrant not exercised on or before the Expiration Date shall become void, and all rights thereunder and all rights in
respect thereof under this Agreement shall cease at the close of business on the Expiration Date. The Company, in its sole discretion, may extend the duration of the Warrants by delaying the Expiration Date. 

3.3 Exercise of Warrants. 
 3.3.1 Exercise and Payment. A registered holder may exercise a Warrant by delivering, not later than 5:00 P.M., Eastern time, on any Business Day during the Exercise Period (the “Exercise
Date”) to the Warrant Agent at its corporate trust department (i) the Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Book-Entry Warrant Certificate, the Warrants to be exercised (the
“Book-Entry Warrants”) on the records of the Depository to an account of the Warrant Agent at the Depository designated for such purpose in writing by the Warrant Agent to the Depository from time to time, (ii) an election to
purchase the Shares underlying the Warrants to be exercised (the “Election to Purchase”), properly completed and executed by the registered holder on the reverse of the Warrant Certificate or, in the case of a Book-Entry Warrant
Certificate, properly delivered by the Participant in accordance with the Depository’s procedures, and (iii), except as provided in 3.3.8, the Exercise Price for each Warrant to be exercised in lawful money of the United States of America by
certified or official bank check or by bank wire transfer in immediately available funds.
 If any of (A) the Warrant
Certificate or the Book-Entry Warrants, (B) the Election to Purchase, or (C) the Warrant Price therefor, is received by the Warrant Agent after 5:00 P.M., Eastern time, on the specified Exercise Date, the Warrants will be deemed to be
received and exercised on the Business Day next succeeding the Exercise Date. If the date specified as the Exercise Date is not a Business Day, the Warrants will be deemed to be received and exercised on the next succeeding day that is a Business
Day. If the Warrants are received or deemed to be 

  
 3 

 
received after the Expiration Date, the exercise thereof will be null and void and any funds delivered to the Warrant Agent will be returned to the registered holder or Participant, as the case
may be, as soon as practicable. In no event will interest accrue on funds deposited with the Warrant Agent in respect of an exercise or attempted exercise of Warrants. The validity of any exercise of Warrants will be determined by the Company in its
sole discretion and such determination will be final and binding upon the registered holder and the Warrant Agent. Neither the Company nor the Warrant Agent shall have any obligation to inform a registered holder of the invalidity of any exercise of
Warrants. 
 The Warrant Agent shall deposit all funds received by it in payment of the Warrant Price in the account of the
Company maintained with the Warrant Agent for such purpose and shall advise the Company at the end of each day on which funds for the exercise of the Warrants have been received and the amount so deposited to its account. The Warrant Agent shall
promptly confirm such telephonic advice to the Company in writing.
 3.3.2 Issuance of Certificates. The Warrant Agent
shall, within a reasonable time, advise the Company and the transfer agent and registrar in respect of (a) the Shares issuable upon such exercise as to the number of Warrants exercised in accordance with the terms and conditions of this
Agreement, (b) the instructions of each registered holder or Participant, as the case may be, with respect to delivery of the Warrant Shares issuable upon such exercise, and the delivery of definitive Warrant Certificates, as appropriate,
evidencing the balance, if any, of the Warrants remaining after such exercise, (c) in case of a Book-Entry Warrant Certificate, the notation that shall be made to the records maintained by the Depository, its nominee for each Book-Entry Warrant
Certificate, or a Participant, as appropriate, evidencing the balance, if any, of the Warrants remaining after such exercise and (d) such other information as the Company or such transfer agent and registrar shall reasonably require.

 The Company shall, by 5:00 P.M., Eastern time, on the third Business Day next succeeding the Exercise Date of any Warrant and
the clearance of the funds in payment of the Exercise Price (or upon surrender of the Warrant, or portion thereof, as set forth in Section 3.3.7) (the “Warrant Shares Delivery Date”), execute, issue and deliver to the Warrant
Agent, the Warrant Shares to which such registered holder or Participant, as the case may be, is entitled, in fully registered form, registered in such name or names as may be directed by such registered holder or the Participant, as the case may
be. Upon receipt of such Warrant Shares, the Warrant Agent shall, by 5:00 P.M., Eastern Time, on the third Business Day next succeeding such Exercise Date, transmit such Warrant Shares to or upon the order of the registered holder or Participant, as
the case may be. If any such Warrant shall not have been exercised in full, a new countersigned Warrant for the number of shares as to which such Warrant shall not have been exercised shall be delivered to the registered holder or Participant, as
the case may be. 
 In lieu of delivering physical certificates representing the Warrant Shares issuable upon exercise, provided
the Company’s transfer agent is participating in the Depository’s Fast Automated Securities Transfer program, the Company shall use its reasonable best efforts to cause its transfer agent to electronically transmit the Warrant Shares
issuable upon exercise to the registered holder or the Participant by crediting the account of the registered holder’s prime broker with the Depository or of the Participant through its Deposit Withdrawal Agent Commission system. The time
periods for delivery described in the immediately preceding 

  
 4 

 
paragraph shall apply to the electronic transmittals described herein. If the Warrant Agent fails to comply with the preceding paragraphs in this Section 3.3.2 by the Warrant Shares
Delivery Date, then the registered holder will have the right to rescind its exercise. 
 Notwithstanding the foregoing, the
Company shall not be obligated to deliver any securities pursuant to the exercise of a Warrant unless (a) a registration statement under the Act with respect to the Common Stock issuable upon exercise of such Warrants is effective and a current
prospectus relating to the shares of Common Stock issuable upon exercise of the Warrants is available for delivery to the Warrant holders or (b) in the opinion of counsel to the Company, the exercise of the Warrants is exempt from the
registration requirements of the Act and such securities are qualified for sale or exempt from qualification under applicable securities laws of the states or other jurisdictions in which the registered holder resides. Warrants may not be exercised
by, or securities issued to, any registered holder in any state in which such exercise or issuance would be unlawful. In the event that a registration statement under the Act with respect to the Common Stock underlying the Warrants is not effective
or a current prospectus is not available, or because such exercise would be unlawful with respect to a registered holder in any state, the registered holder shall not be entitled to exercise such Warrants and such Warrants may have no value and
expire worthless. 
 3.3.3 Valid Issuance. All shares of Common Stock issued upon the proper exercise of a Warrant in
conformity with this Warrant Agreement shall be validly issued, fully paid and nonassessable. 
 3.3.4 Date of Issuance.
Each person in whose name any such certificate for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares on the date on which the Warrant was surrendered and payment of the Exercise
Price was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder
of such shares at the close of business on the next succeeding date on which the stock transfer books are open. 
 3.3.5 No
Fractional Exercise. No fractional Warrant Shares shall be issued upon the exercise of any Warrant. As to any fraction of a Warrant Share which the registered holder would otherwise be entitled to purchase upon such exercise, the Company shall,
at its election, either pay a cash adjustment in respect of such fraction in an amount equal to such fraction multiplied by the Exercise Price or round up such fraction to the nearest whole share. If fewer than all of the Warrants evidenced by a
Warrant Certificate are exercised, a new Warrant Certificate for the number of unexercised Warrants remaining shall be executed by the Company and countersigned by the Warrant Agent as provided in Section 2 of this Warrant Agreement, and
delivered to the holder of this Warrant Certificate at the address specified on the books of the Warrant Agent or as otherwise specified by such registered holder. If fewer than all the Warrants evidenced by a Book-Entry Warrant Certificate are
exercised, a notation shall be made to the records maintained by the Depository, its nominee for each Book-Entry Warrant Certificate, or a Participant, as appropriate, evidencing the balance of the Warrants remaining after such exercise. 

3.3.6 No Transfer Taxes. The Company shall not be required to pay any stamp or other tax or governmental charge required to be
paid in connection with any transfer involved 

  
 5 

 
in the issue of the Warrant Shares upon the exercise of Warrants; and in the event that any such transfer is involved, the Company shall not be required to issue or deliver any Warrant Shares
until such tax or other charge shall have been paid or it has been established to the Company’s satisfaction that no such tax or other charge is due. 
 3.3.7 Optional Cashless Exercise. If at any time during the term of this Warrant there is no effective Registration Statement registering, or no current prospectus available for, the issuance or
resale of the Warrant Shares by the registered holder, then this Warrant may also be exercised at such time by means of a “cashless exercise” in which the registered holder shall be entitled to receive a certificate for the number of
Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A), where: 
  

			
	(A)	  	= the VWAP (as defined below) on the Trading Day immediately preceding the date of such election;
		
	(B)	  	= the Exercise Price of this Warrant, as adjusted; and
		
	(X)	  	= the number of Warrant Shares issuable upon exercise of this Warrant in accordance with the terms of this Warrant by means of a cash exercise rather than a cashless
exercise.

 The term “VWAP” means, for any date, the price determined by the first of the following
clauses that applies: (a) if the Common Stock is then listed or quoted on a Trading Market (as defined below), the daily volume weighted average price of the Common Stock for such date (or the nearest preceding date) on the Trading Market on
which the Common Stock is then listed or quoted as reported by Bloomberg L.P. (based on a Trading Day from 9:30 a.m. (New York City time) to 4:02 p.m. (Eastern time), (b) if the OTC Bulletin Board is not a Trading Market, the volume weighted
average price of the Common Stock for such date (or the nearest preceding date) on the OTC Bulletin Board, (c) if the Common Stock is not then listed or quoted for trading on the OTC Bulletin Board and if prices for the Common Stock are then
reported in the “Pink Sheets” published by Pink Sheets, LLC (or a similar organization or agency succeeding to its functions of reporting prices), the most recent bid price per share of the Common Stock so reported, or (d) in all
other cases, the fair market value of a share of Common Stock as determined by an independent appraiser selected in good faith by the Warrant Agent and reasonably acceptable to the Company, the fees and expenses of which shall be paid by the
Company. 
 The term “Trading Market” means any of the following U.S. markets or exchanges on which the Common
Stock is listed or quoted for trading on the date in question: the NYSE, NYSE AMEX, the NASDAQ Capital Market, the NASDAQ Global Market or the NASDAQ Global Select Market (or any successors to any of the foregoing). 

3.3.8 Disputes. In the case of a dispute as to the determination of the Exercise Price or the arithmetic calculation of the
Warrant Shares, the Company shall promptly issue to the registered holder the number of Warrant Shares that are not disputed. 

  
 6 

 3.3.9 Limitations on Exercise. The Warrant Agent shall not effect any exercise of
this Warrant, and a registered holder shall not have the right to exercise any portion of this Warrant to the extent that after giving effect to such issuance after exercise as set forth on the applicable exercise notice, the registered holder
(together with the registered holder’s Affiliates, and any other person or entity acting as a group together with the registered holder or any of the registered holder’s Affiliates), would beneficially own in excess of the Beneficial
Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the registered holder and its Affiliates shall include the number of shares of Common Stock issuable upon
exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (A) exercise of the remaining, non-exercised portion of this Warrant
beneficially owned by the registered holder or any of its Affiliates and (B) exercise or conversion of the unexercised or non-converted portion of any other securities of the Company (including, without limitation, any other equity equivalent
securities) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the registered holder or any of its Affiliates. Except as set forth in the preceding sentence, for purposes of this
Section 3.3.9, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934 and the rules and regulations promulgated thereunder (the “Exchange Act”), it being
acknowledged by the registered holder that the Company is not representing to the registered holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the registered holder is solely responsible for any schedules
required to be filed in accordance therewith. To the extent that the limitation contained in this Section 3.3.9 applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the registered holder
together with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the registered holder, and the submission of an exercise notice shall be deemed to be the registered holder’s determination of
whether this Warrant is exercisable (in relation to other securities owned by the registered holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject the Beneficial Ownership Limitation, and the
Company and the Warrant Agent shall have no obligation to verify or confirm the accuracy of such determination. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of
the Exchange Act. For purposes of this Section 3.3.9, in determining the number of outstanding shares of Common Stock, a registered holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s
most recent periodic or annual report as the case may be, (B) a more recent public announcement by the Company or (C) any other notice by the Company or its transfer agent setting forth the number of shares of Common Stock outstanding.
Upon the written or oral request of a registered holder, the Company shall within three (3) Business Days confirm orally and in writing to the registered holder the number of shares of Common Stock then outstanding. In any case, the number of
outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the registered holder or its Affiliates since the date as of which such number of
outstanding shares of Common Stock was reported. 
 The “Beneficial Ownership Limitation” shall be 4.99% of the
number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of this Warrant. The registered holder, upon not less than sixty one

  
 7 

 
(61) days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section, provided that the Beneficial Ownership Limitation in no event
exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon exercise of this Warrant held by the registered holder and the provisions of this Section 3.3.9
shall continue to apply. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Company. The provisions of this Section 3.3.9 shall be construed, corrected and implemented in a manner so as
to effectuate the intended Beneficial Ownership Limitation herein contained. The limitations contained in this paragraph shall apply to a successor holder of this Warrant. 
 4. Adjustments. 
 4.1 Stock Dividends - Split-Ups. If, after the
date hereof but prior to the Expiration Date, and subject to the provisions of Section 4.6 below, the number of outstanding shares of Common Stock of the Company is increased by a stock dividend payable in shares of Common Stock, or by a
split-up of shares of Common Stock, or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be increased in proportion to
such increase in outstanding shares of Common Stock. 
 4.2 Aggregation of Shares. If, after the date hereof but prior to
the Expiration Date, and subject to the provisions of Section 4.6, the number of outstanding shares of Common Stock of the Company is decreased by a consolidation, combination, reverse stock split or reclassification of shares of Common Stock
or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable on exercise of each Warrant shall be decreased in
proportion to such decrease in outstanding shares of Common Stock. 
 4.3 Adjustments in Exercise Price. Whenever the
number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in Sections 4.1 and 4.2 above, the Exercise Price shall be adjusted (to the nearest cent) by multiplying such Exercise Price immediately prior to
such adjustment by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number
of shares of Common Stock purchasable under the Warrants immediately thereafter. 
 4.4 Replacement of Securities upon
Reorganization, etc. In case of any reclassification or reorganization of the outstanding shares of Common Stock (other than a change covered by Section 4.1 or 4.2 hereof or one that solely affects the par value of such shares of Common
Stock), or, in the case of any merger or consolidation of the Company with or into another corporation (other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification or
reorganization of the outstanding shares of Common Stock), or, in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety or substantially as an entirety, in connection with
which the Company is dissolved, the Warrant holders shall thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the shares of Common Stock of the

  
 8 

 
Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including
cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the Warrant holder would have received if such Warrant holder had exercised his, her or its
Warrant(s) immediately prior to such event; and if any reclassification also results in a change in shares of Common Stock covered by Section 4.1 or 4.2, then such adjustment shall be made pursuant to Sections 4.1, 4.2, 4.3 and this
Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. 

4.5 Notices of Changes in Warrant. Upon every adjustment of the Exercise Price or the number of shares issuable upon exercise of a
Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Exercise Price resulting from such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the
exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3 or 4.4, then, in any such event, the Company
shall give written notice to each Warrant holder, at the last address set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein, shall not affect the
legality or validity of such event. 
 4.6 No Fractional Shares. Notwithstanding any provision contained in this Warrant
Agreement to the contrary, the Company shall not issue fractional shares upon exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such Warrant,
to receive a fractional interest in a share, the Company shall, upon such exercise, round up or down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder. 

4.7 Form of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and
Warrants issued after such adjustment may state the same Exercise Price and the same number of shares as is stated in the Warrants initially issued pursuant to this Warrant Agreement. However, the Company may, at any time, in its sole discretion,
make any change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or
otherwise, may be in the form as so changed. 
 5. Transfer and Exchange of Warrants. 

5.1 Registration of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant in the
Warrant Register, upon surrender of such Warrant for transfer, properly endorsed with signatures properly medallion guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing an equal
aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. The Warrants so cancelled may be delivered by the Warrant Agent to the Company from time to time upon request. 

  
 9 

 5.2 Procedure for Surrender of Warrants. Warrants may be surrendered to the Warrant
Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the registered holder of the Warrants so surrendered, representing an equal
aggregate number of Warrants; provided, however, that except as otherwise provided herein or in any Book-Entry Warrant Certificate, each Book-Entry Warrant Certificate may be transferred only in whole and only to the Depository, to another nominee
of the Depository, to a successor depository, or to a nominee of a successor depository; provided further, however, that in the event that a Warrant surrendered for transfer bears a restrictive legend, the Warrant Agent shall not cancel such Warrant
and issue new Warrants in exchange therefor until the Warrant Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants must also bear a restrictive legend. Upon any such
registration of transfer, the Company shall execute, and the Warrant Agent shall countersign and deliver, in the name of the designated transferee a new Warrant Certificate or Warrant Certificates of any authorized denomination evidencing in the
aggregate a like number of unexercised Warrants. 
 5.3 Fractional Warrants. The Warrant Agent shall not be required to
effect any registration of transfer or exchange which will result in the issuance of a warrant certificate for a fraction of a warrant. 
 5.4 Service Charges. No service charge shall be made for any exchange or registration of transfer of Warrants. 
 5.5 Warrant Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required to be issued
pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, will supply the Warrant Agent with Warrants duly executed on behalf of the Company for such purpose. 

6. Other Provisions Relating to Rights of Holders of Warrants. 
 6.1 No Rights as Stockholder. Except as otherwise specifically provided herein, a registered holder, solely in its capacity as a holder of a Warrant, shall not be entitled to vote or receive
dividends or be deemed the holder of share capital of the Company for any purpose, nor shall anything contained in this Warrant Agreement be construed to confer upon a registered holder, solely in its capacity as the registered holder of a Warrant,
any of the rights of a stockholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of stock, reclassification of stock, consolidation, merger, conveyance or otherwise), receive
notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the registered holder of the Warrant Shares which it is then entitled to receive upon the due exercise of a Warrant. A Warrant does not entitle the
registered holder thereof to any of the rights of a stockholder. 
 6.2 Lost, Stolen, Mutilated, or Destroyed Warrants.
If any Warrant is lost, stolen, mutilated or destroyed, the Company and the Warrant Agent may, on such terms as to indemnity or otherwise as they may in their discretion impose (which terms shall, in the case of a mutilated Warrant, include the
surrender thereof), issue a new Warrant of like denomination, tenor and 

  
 10 

 
date as the Warrant so lost, stolen, mutilated or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not the allegedly lost, stolen,
mutilated or destroyed Warrant shall be at any time enforceable by anyone. 
 6.3 Reservation of Common Stock. The
Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Warrant Agreement.

 7. Concerning the Warrant Agent and Other Matters. 
 7.1 Payment of Taxes. The Company will from time to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery of
shares of Common Stock upon the exercise of Warrants, but the Company shall not be obligated to pay any transfer taxes in respect of the Warrants or such shares. 
 7.2 Resignation, Consolidation, or Merger of Warrant Agent. 
 7.2.1
Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in
writing to the Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to
make such appointment within a period of 30 days after it has been notified in writing of such resignation or incapacity by the Warrant Agent or by the holder of the Warrant (who shall, with such notice, submit his, her or its Warrant for inspection
by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether
appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good standing and having its principal office in the Borough of Manhattan, City and State of New York, and
authorized under such laws to exercise corporate trust powers and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with all the authority, powers, rights, immunities,
duties, and obligations of its predecessor Warrant Agent with like effect as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Warrant Agent
shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent
the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and
obligations. 
 7.2.2 Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the
Company shall give notice thereof to the predecessor Warrant Agent and the transfer agent for the Common Stock not later than the effective date of any such appointment. 

  
 11 

 7.2.3 Merger or Consolidation of Warrant Agent. Any corporation into which the
Warrant Agent may be merged or with which it may be consolidated or any corporation resulting from any merger or consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further
act. 
 7.3 Fees and Expenses of Warrant Agent. 
 7.3.1 Remuneration. The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and will reimburse the Warrant Agent upon demand for all
expenditures that the Warrant Agent may reasonably incur in the execution of its duties hereunder. 
 7.3.2 Further
Assurances. The Company agrees to perform, execute, acknowledge and deliver or cause to be performed, executed, acknowledged and delivered all such further and other acts, instruments and assurances as may reasonably be required by the Warrant
Agent for the carrying out or performing of the provisions of this Warrant Agreement.
 7.4 Liability of Warrant Agent.

 7.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Warrant Agreement the
Warrant Agent shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein
specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the Chief Executive Officer, Chief Financial Officer, President or Chairman of the Board of the Company and delivered to the Warrant Agent. The
Warrant Agent may rely upon such statement for any action taken or suffered in good faith by it pursuant to the provisions of this Agreement. 
 7.4.2 Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct or bad faith. The Company agrees to indemnify the Warrant Agent and save it
harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross negligence,
willful misconduct or bad faith. 
 7.4.3 Exclusions. The Warrant Agent shall have no responsibility with respect to the
validity of this Warrant Agreement or with respect to the validity or execution of any Warrant (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Warrant
Agreement or in any Warrant; nor shall it be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner, method or amount of any such adjustment or the ascertaining of the existence of
facts that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any shares of Common Stock to be issued pursuant to this Warrant Agreement or
any Warrant or as to whether any shares of Common Stock will when issued be valid and fully paid and nonassessable. 

  
 12 

 7.5 Acceptance of Agency. The Warrant Agent hereby accepts the agency established by
this Warrant Agreement and agrees to perform the same upon the terms and conditions herein set forth and, among other things, shall account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the
Company, all moneys received by the Warrant Agent for the purchase of shares of Common Stock through the exercise of Warrants. 
 8.
Miscellaneous Provisions.

benefit of the Company or the Warrant Agent shall bind and inure to the benefit of their respective successors and assigns.

 8.3 Applicable Law. The validity, interpretation and performance of this Warrant
Agreement and of the Warrants shall be governed in all respects by the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The
Company hereby agrees that any action, proceeding or claim against it arising out of or relating in any way to this Warrant Agreement shall be brought and enforced in the courts of the State of New York or the United States District Court for the
Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive. The Company hereby waives any objection to such exclusive jurisdiction and that such courts represent an inconvenient forum. Any such

mailing shall be deemed personal service and shall be legal and binding upon the Company in any action, proceeding or claim. 

8.4 Persons Having Rights under this Agreement. Nothing in this Warrant Agreement expressed and nothing that may be implied from
any of the provisions hereof is intended, or shall be construed, to confer upon, or give to, any person or corporation other than the parties hereto and the registered holders of the Warrants, any right, remedy, or claim under or by reason of this
Warrant Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations, promises, and agreements contained in this Warrant Agreement shall be for the sole and exclusive benefit of the
parties hereto and their successors and assigns and of the registered holders of the Warrants. 
 8.5 Examination of the
Warrant Agreement. A copy of this Warrant Agreement shall be available at all reasonable times at the office of the Warrant Agent in the Borough of Manhattan, City and State of New York, for inspection by the registered holder of any Warrant.
The Warrant Agent may require any such holder to submit his, her or its Warrant for inspection by it. 
 8.6
Counterparts. This Warrant Agreement may be executed in any number of original or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but
one and the same instrument. 
 8.7 Effect of Headings. The section headings herein are for convenience only and are not
part of this Warrant Agreement and shall not affect the interpretation thereof. 
 8.8 Amendments. This Warrant Agreement
may be amended by the parties hereto without the consent of any registered holder: (i) for the purpose of curing any ambiguity, or curing, correcting or supplementing any defective provision contained herein or (ii) adding or changing any
other provisions with respect to matters or questions arising under this Warrant Agreement as the parties may deem necessary or desirable and that the parties deem shall not adversely affect the interest of the registered holders. All other
modifications or amendments, including any amendment to increase the Exercise Price or shorten the Exercise Period, shall 

  
 14 

 
require the written consent of the registered holders of a majority of the then outstanding Warrants. Notwithstanding the foregoing, the Company may lower the Exercise Price or extend the

8.9 Severability. Whenever possible, each provision of this Warrant Agreement shall be interpreted in such manner as to be

 AUTHENTIDATE HOLDING CORP.

VOID AFTER 5:00 P.M., NEW YORK TIME, 
 ON JUNE 17, 2018 
 This certifies that
                     or registered assigns is the registered holder of
                     warrants to purchase certain securities (each a “Warrant”). Each Warrant entitles the holder thereof, subject
to the provisions contained herein and in the Warrant Agreement (as defined below), to purchase from Authentidate Holding Corp., a Delaware corporation (the “Company”),
[                ] shares (collectively, the “Warrant Shares”) of Common Stock, par value $0.001 per share, of the Company (“Common
Stock”), at the Exercise Price set forth below. The price per share at which each Warrant Share may be purchased at the time each Warrant is exercised (the “Exercise Price”) is $0.95 initially, subject to adjustments as set
forth in the Warrant Agreement (as defined below). 
 Capitalized terms used but not defined herein shall have the meaning
ascribed to them in the Warrant Agreement. 
 Subject to the terms of the Warrant Agreement, each Warrant evidenced hereby may
be exercised at any time, as specified herein, on any Business Day (as defined below) occurring during the period (the “Exercise Period”) commencing the date hereof and terminating at 5:00 P.M., New York City time, on June 17,
2018 (the “Expiration Date”). Each Warrant remaining unexercised after 5:00 P.M., New York City time, on the Expiration Date shall become void, and all rights of the holder of this Warrant Certificate evidencing such Warrant shall
cease. 
 The holder of the Warrants represented by this Warrant Certificate may exercise any Warrant evidenced hereby by
delivering, not later than 5:00 P.M., New York time, on any Business Day during the Exercise Period (the “Exercise Date”) to Continental Stock Transfer & Trust Co. (the “Warrant Agent”, which term
includes any successor warrant agent under the Warrant Agreement described below) at its office designated for such purpose at 17 Battery Place, New York, NY 10004, (i) this Warrant Certificate or, in the case of a Book-Entry Warrant
Certificate (as defined in the Warrant Agreement), the Warrants to be exercised (the “Book-Entry Warrants”) as shown on the records of The Depository Trust Company (the 

  
 17 

 
“Depository”) to an account of the Warrant Agent at the Depository designated for such purpose in writing by the Warrant Agent to the Depository, (ii) an election to
purchase (“Election to Purchase”), properly executed by the holder hereof on the reverse of this Warrant Certificate or properly executed by the institution in whose account the Warrant is recorded on the records of the Depository
(the “Participant”), and substantially in the form included on the reverse of this Warrant Certificate and (iii) the Exercise Price for each Warrant to be exercised, and all applicable taxes and charges due in connection
therewith, in lawful money of the United States of America by certified or official bank check or by bank wire transfer in immediately available funds. 
 As used herein, the term “Business Day” means any day other than Saturday, Sunday or other day on which commercial banks in The City of New York are authorized or required by law or
executive order to remain closed. 
 Warrants may be exercised only in whole numbers of Warrants. No fractional Warrant Shares
are to be issued upon the exercise of this Warrant, but rather the number of Warrant Shares to be issued shall be rounded up or down, as applicable, to the nearest whole number. If fewer than all of the Warrants evidenced by this Warrant Certificate
are exercised, a new Warrant Certificate for the number of Warrants remaining unexercised shall be executed by the Company and countersigned by the Warrant Agent as provided in Section 2 of the Warrant Agreement, and delivered to the registered
holder of this Warrant Certificate at the address specified on the books of the Warrant Agent or as otherwise specified by such registered holder. 
 This Warrant Certificate is issued under and in accordance with the Warrant Agreement, dated as of June , 2013 (the “Warrant Agreement”), between the Company and the Warrant Agent and is
subject to the terms and provisions contained in the Warrant Agreement, to all of which terms and provisions the holder of this Warrant Certificate and the beneficial owners of the Warrants represented by this Warrant Certificate consent by
acceptance hereof. Copies of the Warrant Agreement are on file and can be inspected at the above-mentioned office of the Warrant Agent and at the office of the Company at Connell Corporate Center, 300 Connell Drive, Suite 5100, Berkeley Heights, NJ
07922. 
 The Company shall provide to the registered holder prompt written notice of any time that the Company is unable to
issue the Warrant Shares via DTC transfer or otherwise (without restrictive legend), because (A) the Commission has issued a stop order with respect to the Registration Statement, (B) the Commission otherwise has suspended or withdrawn the
effectiveness of the Registration Statement, either temporarily or permanently, (C) the Company has suspended or withdrawn the effectiveness of the Registration Statement, either temporarily or permanently, or (D) otherwise (each a
“Restrictive Legend Event”). To the extent that a Restrictive Legend Event occurs after the registered holder has exercised a Warrant in accordance with the terms of the Warrants but prior to the delivery of the Warrant Shares, the
Company shall, at the election of the registered holder, which shall be given within five (5) days of receipt of notice of the Restrictive Legend Event, either (A) rescind the previously submitted Election to Purchase and the Company shall
return all consideration paid by registered holder for such shares upon such rescission or (B) treat the attempted exercise as a cashless exercise as described in the Warrant Agreement. 

  
 18 

 The Exercise Price and the number of Warrant Shares purchasable upon the exercise of each
Warrant shall be subject to adjustment as provided pursuant to Section 4 of the Warrant Agreement. 
 Upon due presentment
for registration of transfer or exchange of this Warrant Certificate at the office of the Warrant Agent designated for such purpose, the Company shall execute, and the Warrant Agent shall countersign and deliver, as provided in Section 5 of the
Warrant Agreement, in the name of the designated transferee one or more new Warrant Certificates of any authorized denomination evidencing in the aggregate a like number of unexercised Warrants, subject to the limitations provided in the Warrant
Agreement. 
 Neither this Warrant Certificate nor the Warrants evidenced hereby entitles the registered holder thereof to any
of the rights of a shareholder of the Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as shareholders in respect of the
meetings of shareholders or the election of directors of the Company or any other matter. 
 The Warrant Agreement and this
Warrant Certificate may be amended as provided in the Warrant Agreement including, under certain circumstances described therein, without the consent of the holder of this Warrant Certificate or the Warrants evidenced thereby. 

THIS WARRANT CERTIFICATE AND ALL RIGHTS HEREUNDER AND UNDER THE WARRANT AGREEMENT SHALL BE GOVERNED BY AND INTERPRETED AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS FORMED AND TO BE PERFORMED ENTIRELY WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO THE CONFLICTS OF LAW PROVISIONS THEREOF TO THE EXTENT SUCH PRINCIPLES OR RULES WOULD
REQUIRE OR PERMIT THE APPLICATION OF THE LAWS OF ANOTHER JURISDICTION. 
 This Warrant Certificate shall not be entitled to
any benefit under the Warrant Agreement or be valid or obligatory for any purpose, and no Warrant evidenced hereby may be exercised, unless this Warrant Certificate has been countersigned by the manual signature of the Warrant Agent.

 IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed.
